The Issue The issue is whether Respondent Win-Suncoast, Ltd., is entitled to an individual environmental resource permit to construct a surface water management system to serve a proposed shopping center.
Findings Of Fact On April 25, 2006, Applicant filed with District an application for an individual ERP to construct a surface water management system on a parcel located in south Pasco County on the north side of State Road 54, about 1000 feet east of the right-of-way of the Suncoast Parkway. The proposed surface water management system would serve the commercial development of the now-vacant, 36.7-acre parcel. State Road 54 runs from State Road 19 near New Port Richey to Interstate 75; at the Suncoast Parkway, State Road 54 is six lanes wide. The Suncoast Parkway is a limited-access toll road that runs from Memorial Parkway in Tampa to U.S. Route 98 north of Brooksville. The subject parcel is about one mile north of Hillsborough County, four miles east of the terminus of Gunn Highway at State Road 54, and five miles west of State Road The vicinity of this intersection is experiencing rapid commercial development and escalating land values, mostly since the completion of the Suncoast Parkway in 2001. Three parcels adjoin the subject parcel. Immediately north of the subject parcel is the Ashley Glen parcel, which consists of 266.36 acres. Immediately west of the subject parcel and the Ashley Glen parcel is the parcel owned by Petitioner. Petitioner's parcel has about 700 feet of frontage on State Road 54 and runs the length of the western borders of the subject parcel and the Ashley Glen parcel. The northern border of Petitioner's parcel and the Ashley Glen parcel is an abandoned railroad grade. Immediately east of the subject parcel is a DOT-owned parcel, which serves as floodplain mitigation, probably in connection with the Suncoast Parkway or State Road 54. Petitioner challenged the issuance of an ERP in two administrative cases involving the Ashley Glen parcel. In the Blanco I final order, which is dated January 25, 2005, the District denied an ERP for a surface water management system to serve the development of a residential subdivision of over 400 lots. The ERP was denied due to the applicant's failure to conduct an appropriate wildlife survey and to account for the effect of a newly excavated 37-acre borrow pit/pond on a large forested wetland partly occupying a large area on the north end of Petitioner's property. After the developer submitted a revised application, Petitioner challenged the ERP that District proposed to issue. After an administrative hearing, District granted an ERP in the Blanco II final order, which is dated May 30, 2006. Significant differences in the second application were that the applicant had reduced the maximum depth of the borrow pit/pond from 25 feet to 12 feet, under most circumstances, and that the applicant had obtained an appropriate wildlife survey. The subject parcel is about 1.5 miles south of a large tract proposed for acquisition by District and known as the Masaryktown Canal area. This tract would join the smaller Starkey tract, which is also owned by District, with another somewhat smaller publicly owned tract to place much of central Pasco County, from Hillsborough County to Hernando County, in public ownership. Water from the subject parcel drains north toward central Pasco County and then into the Anclote River. The record is in conflict as to the drainage basin in which the subject parcel is located. According to BOR Appendix 6, which is dated May 2, 2006, the subject parcel is in the southern end of the Upper Coastal Drainage basin, which is a vast basin that stretches down the Gulf coast from north of Crystal River to the southern tip of Pinellas County. At points, this basin is not wide, such as at the southern tip of Pinellas County, where, just a few miles inland, the Tampa Bay Drainage basin begins. At other places, the Upper Coastal Drainage basin extends considerably inland, such as at the Pasco County--Hernando County line, where the basin extends about 25 miles east from the Gulf coast, ending only five miles west of the Withlacoochee River. According to District Exhibit 5, which is the District Land Acquisition Priorities Map issued in December 2004, the subject parcel is in the Tampa Bay/Anclote River Watershed. On this map, a large, unnamed watershed, corresponding roughly to the Upper Coastal Drainage basin in BOR Appendix 6, runs to the north of the subject parcel's watershed. At the hearing, District explained that the boundaries shown on District Exhibit 5 identify political subdivisions. The "basins," which are marked in green letters, appear to be political subdivisions, judging from their straight lines, which suggest political, not natural, boundaries. However, the "watersheds," which are marked in larger blue letters, are actual drainage basins. Applicant's ecologist initially believed that the subject parcel was in the Hillsborough watershed. Also, the basin map shown on the District website, District depicts the subject parcel's basin (here named the "Pinellas--Anclote River Basin") as that south of the large basin (here named the "Coastal Basin") encompassing almost the entire coast within the northern area of District's jurisdiction1. Factually, the stronger evidence places the subject parcel in a basin to the south of the large coastal basin described in the preceding paragraphs. However, for the reasons discussed in the Conclusions of Law, the basin depicted in BOR Appendix 6 governs. Although not yet constructed, an important feature of the subject parcel is a road to be known as Ashley Glen Road. This road will nearly bisect the property and will run north from State Road 54 through the Ashley Glen parcel. The road is likely to be developed because it has already been permitted, is subject to a co-developers' agreement, and has already been dedicated to Pasco County. The developer in Blanco I and Blanco II has since sold the Ashley Glen parcel to another developer, which has substantially changed the original plan of development. The new developer has obtained a Development of Regional Impact approval for the development of 1.8 million square feet of office, 450,000 square feet of retail, and 900 multifamily units. However, the new development will incorporate Ashley Glen Road. (For ease of reference, this recommended order continues to use the name, "Ashley Glen" to refer to the parcel, development, and road, although new names may attach to each.) At present, the subject parcel conveys stormwater from south to north. Running along the eastern edge of the parcel is a 20-foot-wide ditch that receives water, by way of a culvert under State Road 54, from the extensive wetland system known as the Hogan wetland, which lies to the south of State Road 54. The ditch was dredged (or re-dredged) about 50 years ago. From south to north, the ditch runs straight in a north-northwesterly direction to about midpoint on the subject parcel, at which point the ditch turns due north and runs in nearly a straight line into and along the eastern part of the Ashley Glen parcel to the north. The northern part of the Ashley Glen parcel widens in an easterly direction, so the ditch bisects this part of the Ashley Glen parcel, prior to turning to the northwest for a short run to the railroad grade. There are two wetlands presently on the subject parcel. In the southeast corner is an isolated wetland known as Wetland B12, which has been described above. The ERP approved in Blanco II authorizes the filling of this entire wetland, whose eastern third would be occupied by Ashley Glen Road. The Blanco II final order determines that Wetland B12 is a "low-quality, small (0.58 acres), isolated, forested wetland that has been impacted by livestock grazing and the intrusion of exotic species." (Recommended Order, paragraph 11.) The Ashley Glen developer originally intended to create on its property an 18-acre littoral shelf to mitigate wetland losses, including the loss of Wetland B12. However, the sale of the Ashley Glen parcel and adoption of a new development plan have delayed the creation of the littoral shelf. Applicant has thus proposed new mitigation in the form of a mitigation bank credit for the impact to Wetland B12. By this means, Applicant seeks permission to fill the wetland and proceed with development without waiting for the new Ashley Glen developer to create the mitigation for Wetland B12. Although the already-permitted loss of Wetland B12 is not an issue in this case, the mitigation for its loss is an issue. Because Applicant is proposing new mitigation for the loss of Wetland B12, it is necessary to determine whether Applicant, using the methodology adopted by District, has provided reasonable assurance that the functional gain from the proposed mitigation for Wetland B12 offsets the functional loss from its filling. The other wetland on the subject parcel is Wetland C12, which is a nine-acre contiguous wetland. The final order resulting from Blanco II authorizes no impact to Wetland C12, so its loss and the mitigation for the loss are issues in this case. The subject application proposes no impact to 4.5 acres of Wetland C12, permanent loss of 3.1 acres, and temporary loss of 1.4 acres (due to the realignment of part of the ditch, which is within Wetland C12). The part of Wetland C12 proposed to be destroyed is its southernmost one-third, which lies in the southern half of the subject parcel, immediately west of the west bank of the realigned ditch. Wetland C12 forms part of the conveyance, from south to north, of water from the Hogan wetland to the railroad grade at the northern boundary of the Ashley Glen parcel. Stormwater then accumulates against the railroad grade, runs west along the grade, backs up to contribute hydration to the large forested wetland at the northwest corner of the Ashley Glen parcel and the north half of Petitioner's parcel, and passes under the railroad grade by way of three culverts near the northwest corner of the Ashley Glen parcel. Wetland C12 has been disturbed by agricultural activities, mostly by the formation of the ditch. There is some testimony concerning a stream at this location, but the record does not support such a characterization. Based on the present record, prior to any disturbance, it is equally possible that water was conveyed by a stream, a slough, or sheetflow. For these reasons, the record does not permit a finding that the ditch is a restorable stream. Wetland C12 has little buffer from surrounding land cover and agricultural uses. According to Petitioner's testimony, which is credited, the dredging (or re-dredging) 50 years ago was the work of a nearby landowner who owned a dragline and used it to alleviate flooding near the Hogan wetland, presumably by deepening and widening the ditch. The hydrology of Wetland C12 has been altered, so that nuisance exotics and upland species are present at locations within the wetland, presumably including the portions of the banks hosting large spoil piles from past dredging. No listed species use Wetland C12, and its potential as habitat corridor is limited due to the extensive residential development that has taken place immediately to the west of Wetland C12, the extensive residential and commercial development taking place to the east of Wetland C12, and the barriers posed by the Suncoast Parkway and 280-foot right-of-way of State Road 54. Applicant has presented to District a plan to construct nine freestanding buildings with surface parking on the subject parcel. The plan is to construct, from north to south on the west side of Ashley Glen Road, a retail space of 5000 square feet and 75 parking spaces on 1.17 acres, a strip of nine retail spaces of 10,500 square feet and 61 parking spaces on 2.02 acres, a fast-food restaurant of 3800 square feet and 40 parking spaces on 1.02 acres, a convenience/retail store of 6000 square feet and 44 parking spaces on 1.66 acres, a fast-food restaurant of 3000 square feet and 44 parking spaces on 1.22 acres, and a bank of 4300 square feet and 38 parking spaces on 0.95 acres. On the east side of Ashley Glen Road, the plan is to construct, from south to north, a restaurant of 4700 square feet and 67 parking spaces on 1.19 acres, a bank of 4120 square feet and 43 parking spaces on 1.16 acres, and a supermarket complex. The supermarket complex comprises a supermarket, an attached strip identified as "Retail B," a restaurant abutting Retail B, an attached strip identified as "Retail C," and a restaurant abutting Retail C. The supermarket building is 237 feet by 205 feet and houses a 46,755 square-foot grocery store, and 1876 square-foot liquor store, and 1125 square-foot vestibule; the supermarket building is served by 243 spaces. Retail B comprises six retail spaces of 6500 square feet and 33 parking spaces; the restaurant is 3000 square feet and is allocated 34 parking spaces. Retail C comprises four retail spaces of 5600 square feet and 28 spaces; the restaurant is 3600 square feet and is allocated 40 parking spaces. The previously described bank and restaurant on the east side of Ashley Glen Road front State Road 54. Behind the drive-through lanes of the bank and parking of the restaurant are nearly all of the parking allocated to the supermarket complex. The supermarket faces State Road 54, although it is about 500 feet from the road and is located in the middle of the eastern half of the subject parcel. The liquor store is incorporated into the southwest corner of the supermarket building, which has a truck dock at the northwest corner. Running in a north-south direction, Retail B runs along the entire west side of the supermarket building. A strip of 40 parking spaces separates Retail B from Ashley Glen Road. Retail C is oriented perpendicular to Retail B and extends, in an east-west direction, off the southeast corner of the supermarket building. Wetland C12 would be occupied by the footprint of the eastern half to two-thirds of the supermarket building, half of the parking in front of the supermarket, half of Retail Strip C, and almost half of the restaurant fronting State Road 54 on the east side of Ashley Glen Road. In terms of area, the footprint of the supermarket and parking occupies about two-thirds of the 3.1 acres of Wetland C12 proposed to be permanently lost. Several components make up the proposed surface water management system, in addition to the rooftops and paving described above. Applicant proposes to realign a portion of the ditch running within Wetland C12, so that the southern half of the ditch will run on the extreme eastern edge of the subject parcel. For a short distance, two-thirds of the width of the proposed ditch is located off the subject parcel and on the parcel owned by DOT to the east. Applicant proposes to triple the width of the ditch to 60 feet and deepen it so that its bottom would be 20 feet wide. Applicant proposes impervious surface for the vast majority of the entire southern two-thirds of the parcel. A stormwater collector system would collect water and convey it north under Ashley Glen Road to the northwest corner of the subject parcel. The water would enter a 3.92-acre pond to be excavated at a depth to hold stormwater for 14 days from the design storm event, which is a 100-year, five-day storm. During this period, contaminants would be removed by evaporation, settlement, and skimming. A littoral shelf abutting the pond on the west will also permit the vegetative uptake of contaminants. Applicant has incorporated wet detention using the conservation design method, a design approved by District for improved stormwater treatment when compared to other wet-detention treatment designs. From the littoral shelf, stormwater will pass through an outflow structure and enter Mitigation Area B, which will be a created 1.4-acre cypress wetland at the very northwest corner of the subject parcel. Applicant will apply wetland topsoil from the dredged portions of Wetland C12 to Mitigation Area B to encourage the growth of wetland species. Stormwater will sheetflow through Mitigation Area B, which will enhance water quality treatment. Although District calculates mitigation credit for an area only up to the seasonal high water line, Applicant proposes, not merely to sod the slope ending at the seasonal high water line, as is the common practice, but instead to plant this area with native species, such as pines, palmettos, and wax myrtles. From Mitigation Area B, stormwater flows, by way of a culvert under Ashley Glen Road, to Mitigation Area A, which will be a created 2.5-acre cypress wetland directly across Ashley Glen Road from Mitigation Area A. Applicant will apply wetland topsoil to Mitigation Area A and plant native species on the upland slopes of the created wetland, which will also treat sheetflow prior to its passing east into the adjacent, undisturbed portion of Wetland C12. The vice-president of the managing partner of Applicant testified in the case. He has 20 years' experience in commercial construction sales and retail development. He has developed seven shopping centers anchored by a grocery store (Anchored Centers) and six shopping centers without a grocery- store anchor (Unanchored Centers). The corporate managing partner has developed 43 Anchored Centers and is developing five more. The site-selection process requires analysis of land costs, construction costs, prevailing market rents, outparcel values, zoning, title, environmental issues, and geotechnical issues. Analysis of the locational factors are especially important. These include traffic, residential development, and demographics. The intersection of the Suncoast Parkway and State Road 54 is ideal for the development of an Anchored Center. In the past seven years, 10,000 residential units have been developed in the State Road 54 corridor between State Road 41 and the Suncoast Parkway. The southeast quadrant of this intersection is being developed with mixed uses, including office and retail. A large parcel immediately east of the DOT parcel and Ashley Glen parcel is being developed with commercial uses. The southwest quadrant is being developed with a Super Target. Older residential areas exist to the east and southeast of the subject parcel. Applicant entered a contract to purchase the subject parcel in August 2002 and closed on the purchase in November 2003. It has a contract with Sweetbay Supermarket for the grocery store. The appeal of the Anchored Center is in the synergy between the anchor--the supermarket--and the outparcels. The proposed Anchored Center would be a one-stop destination for the consumer seeking the goods and services associated with a supermarket, bank, restaurant, and allied retail and may thus shorten or reduce the number of motor-vehicle trips. Raw land in the vicinity of the intersection of the Suncoast Parkway and State Road 54 has been appreciating at a monthly rate of about three percent during the past four or five years. Parcels in Anchored Centers command a considerable premium over similar parcels in Unanchored Centers, and substantially different business risks attach to each kind of development. One of the differences between the Anchored Center and Unanchored Center is the former's requirement of additional parking. Given this requirement, there was no design modification that would accommodate a shopping center and parking without destroying wetlands. Although Sweetbay Supermarket has a template for a smaller building than the one proposed on the subject site, the smaller building is typically reserved for urban settings, and nothing in the record suggests that even the smaller building, with surface parking, would spare the wetlands completely. In its site-planning exercises, Applicant tried to reduce wetland impacts by moving the supermarket to different locations on the subject parcel. The supermarket will not fit on the west side of Ashley Glen Road. On the east side, Applicant moved it as far west as it could to avoid as much wetland impact as possible given the location of the supermarket at the midpoint of the east side of the subject parcel. The present location represents the best accommodation of the Wetland C12 and the commercial development, at its proposed intensity, that Applicant could find after 8-10 reconfigurations of the site improvements. Given the shape of the subject parcel and Wetland C12, the proposed midpoint location impacts Wetland C12 less than any other location, except right at the northeast corner of the intersection of Ashley Glen Road and State Road 54. However, obvious marketing problems arise with this location. Sweetbay Supermarket understandably desires the supermarket to face State Road 54 to attract business. If the supermarket were located at the northeast corner of these two roads, there would be no parking in the front, requiring the customers to enter from the back, or the back of the supermarket would face State Road 54. In designing the site, Applicant reduced some retail space and associated parking to reduce wetland impacts. At the present midpoint location, the elimination of Retail B and Retail C would permit Applicant to move the building to the west, but this would only slightly reduce the wetland impacts because substantial wetland impacts would occur to the south under the footprint of the parking. Similarly, a parking garage would permit Applicant to avoid those substantial wetland impacts, but not the smaller, but still significant, area of wetland impacts under the footprint of the east side of the supermarket building and Retail C. Of course, Applicant could combine these two modifications--elimination of Retail B and Retail C with the relocation of the supermarket building to the west and the construction of an elevated parking garage on the western half of the proposed footprint of the parking area in front of the supermarket building. Applicant contends that these modifications are not economically practicable. Undoubtedly, parking garages are not typically associated with nonurban development. The vice-president of the managing partner admitted that he had not priced such structures, but estimated that each space in a parking deck would cost 10 times more than each space at grade. With somewhat more authority, he also testified that the loss of any more retail space would leave the development economically unfeasible. Sweetbay Supermarket's declared and presumed preferences also play a role in evaluating this substantial design modification. Sweetbay Supermarket prefers retail on both sides of the supermarket, and, given its need for visibility from State Road 54, it may be presumed not to favor the presence of a multi-story parking garage between its grocery store and State Road 54. Again, placing the parking garage behind the supermarket would gain visibility, but raise the prospect of the back of the supermarket facing State Road 54 or the customers entering the store from the back. These are all plainly unacceptable prospects, without regard to Applicant's notions of economic feasibility or return on investment. Similar considerations apply to the possible realignments of the ditch. In its present alignment, the ditch would be occupied by the footprint of the west half of Retail C, the northeast corner of the supermarket building, as well as parking and paved roadway associated with the supermarket and the restaurant fronting State Road 54 on the east side of Ashley Glen Road. Because the ditch does not extend nearly as far to the west as does Wetland C12, it would be possible to preserve the present ditch by eliminating Retail B and Retail C and shifting the supermarket building to the west with the "extra" parking gained by the elimination of the two retail strips probably offsetting the lost parking in front of the supermarket. But this is a lot to ask to preserve a conveyance that, on this record, does not rise above the homely level of a ditch with its attendant functional limitations, especially when the new ditch will probably relieve existing flooding around the Hogan wetland. Applicant's ecologist applied the Uniform Mitigation Assessment Method (UMAM) to assess Wetlands B12 and C12 and the mitigation areas. UMAM and its applicability to this case are discussed in the Conclusions of Law. Generally, UMAM provides a methodology to determine the functional loss of permanent and temporary wetland impacts and the functional gain of mitigation and ensure that the latter equal or exceed the former. For Wetland B12, Applicant's ecologist determined that its functional value, based on location and landscape support, was 5 out of 10 points due to the isolated nature of the wetland in a pasture, adjacent to a tree farm and absent any buffer. Invasives and exotics are in the adjacent community. Based on water environment, the ecologist scored Wetland B12 with 7 out of 10 points due to the presence of distinct water indicators, although the wetland appears to be dependent on rainfall and had suffered degradation from cattle. Based on community structure, the ecologist scored Wetland B12 with 6 out of 10 points due to its normal appearance for a cypress dome, but evident lack of natural recruitment, presence of nuisance exotics such as primrose willow and Brazilian pepper, and severe degradation from cattle and other agricultural uses. The ecologist's assessment of the permanent impact to 3.1 acres of Wetland C12 and temporary impact to 1.4 acres of the ditch within Wetland C12 followed the same approach, except that the temporary impact to the ditch required an additional step in the process. Applicant's ecologist scored the impacted area of Wetland C12, including the 1.4-acre ditch, with an average functional value of 6.67, based on scores of 7 for location and landscape support, 6 for water environment, and 7 for community structure. The location and landscape support are adversely impacted by the reduced complexity of surrounding uplands, but facilitated by the undeveloped state of the immediate vicinity that would allow use by small- to medium- sized wildlife. The ecologist noted the hydrological connection served by the ditch/wetland network and the narrow riparian corridor provided by this arrangement. The function of the water environment is heightened by the fact that most of the water environment is intact, but suffers from adverse impacts to the hydrology and water quality from the construction of the ditch and conversion of surrounding land cover to pasture and roadway. The community structure is facilitated by the presence of canopy vegetation of cypress, pop ash, and laurel oak, but adversely impacted by the presence of Brazilian pepper in the subcanopy. The additional step required in the analysis of the temporary impacts to 1.4 acres is the projected functional value of the relocated ditch. As compared to the present ditch, the re-created ditch scored one less point in location and landscape support due to the further reduction in adjacent uplands and resulting inhibition on use by medium-size wildlife that currently use the site, one less point in water environment due to some changes in microclimate, nutrient assimilation, and flow characteristics that may adversely affect current wildlife composition, and four fewer points in community structure due to removal of the canopy, subcanopy, and groundcover with the associated seed banks and vegetative growth that could recruit similar species to match existing composition and structure. Based on the foregoing, the ecologist concluded that the permanent functional loss to Wetland B12 was 0.35 units, the permanent functional loss to the 3.1 acres of Wetland C12 was 2.07 units, and the temporary functional loss to the 1.4 acres of Wetland C12/the ditch was 0.28 units, resulting in permanent functional losses of 2.42 units and temporary functional losses of 0.28 units, for a total functional loss of 2.70 units. For onsite mitigation of these functional losses, Applicant proposes Mitigation Areas A and B. Mitigation Area B, which is the 1.4-acre forested wetland to be created on the west side of Ashley Glen Road, received a score of zero in its present undeveloped state, and scores of 4 for location and landscape support, 7 for water environment, and 6 for community structure after it is created. The relatively low score for location and landscape recognizes the limited connectivity (through culverts) to other existing and proposed wetlands, although the lack of barriers for use by birds and aquatic species is a functional advantage. The relatively high score for water environment reflects the hydrological interdependence of Mitigation Area B with the stormwater collection system and created wetlands and the relative reliability of these sources of hydration. The score for community structure reflects the increases in microtopography resulting from the design of high and low wetland areas and the planting of species to create three vegetative strata within the created wetland. The ecologist assigned a time lag factor of 2.73 for this created wetland. Derived from Florida Administrative Code Rule 62-345.600(1)(d), this time lag factor correlates to a time lag of 36-40 years to establish the mitigative functions for which the mitigation site is given credit. The ecologist assigned a risk factor of 2 for this created wetland. Derived from Florida Administrative Code Rule 62-345.600(2), this risk factor correlates to a moderate risk of failure of attaining the functions predicted for the mitigation site. Applying the risk and time lag factors to Mitigation Area B, the ecologist calculated a functional gain of 0.15 units for this 1.4-acre mitigation site. The ecologist used the same methodology for Mitigation Area A, which is the 2.5-acre created wetland across Ashley Glen Road from Mitigation Area B. The ecologist assigned this created wetland a 6 for location and landscape support, a 7 for water environment, and a 7 for community structure. This wetland scored 2 points higher than Mitigation Area B for location and landscape support because it is not isolated by the road and culverts from the unimpacted area of Wetland C12 and offers more upland buffer for small wetland-dependent species. Mitigation Area A scored 1 point higher for community structure due to the likelihood of natural recruitment of seeds from the adjacent unimpacted wetland. For water environment, Mitigation Area A and Mitigation Area B received the same score due to their common characteristics. The ecologist applied the same time lag factor to Mitigation Area A as he did to Mitigation Area B. However, the risk factor was one increment less than moderate, probably due to the hydrological advantages that Mitigation Area A enjoys over Mitigation B due to its pre-existing hydric soils and proximity to the unimpacted wetlands of Wetland C12. Applying the risk and time lag factors to Mitigation Area A, the ecologist calculated a functional gain of 0.35 units for this 2.5-acre site. Applicant's ecologist then calculated the functional gain from the enhancement of the 1.4-acre Wetland C12/ditch. He found an increase of 0.13, as compared to the current value, based on a relatively strong score for the enhanced location and landscape support, average score for the enhanced water environment, and relatively weak score for the enhanced community structure. The enhanced system enjoys functional advantages from the planting of three strata of vegetation along the ditch and emergents in the channel. The ecologist applied a time lag factor of 2.18 (meaning 26-30 years) and a moderate risk factor of 2.0 to obtain a final score of 0.03 acres for this enhancement mitigation. The functional gains and losses for the onsite wetland impacts and mitigation, as determined by Applicant's ecologist, are supported by the record, and his analysis of these losses and gains from the onsite creation and enhancement mitigation is accurate. Next, Applicant purchased a conservation easement as offsite mitigation. This easement is on what is known as the Marr Parcel. The Marr Parcel is a 67.49-acre parcel that sits almost in the middle of a large publicly owned area that runs nearly 30 miles along the coast, from Weeki Wachee to the south to Crystal River to the north. Situated in the north-central part of this large area is the District-owned Chassahowitzka River and Coastal Swamps tract (Chassahowitzka Tract). The Marr Parcel is at the southern end of the Chassahowitzka Tract, about four miles from the Gulf of Mexico. The Marr Parcel is about 33 miles from the subject parcel. The Marr Parcel is in the large coastal basin that, according to BOR Appendix 6, includes the subject parcel and, according to District Exhibit 5, is the basin to the north of the basin that includes the subject parcel. At the end of Zebra Finch Road, the Marr Parcel is surrounded by pristine forested wetland habitat that forms part of an important travel corridor for numerous species, including the Florida black bear. This is a sustainable population of Florida black bears, so this habitat is of critical importance. The forested habitat is a combination of cypress and mixed hardwoods. The larger publicly owned area enveloping the Marr Parcel includes almost every significant habitat present in Florida. Other parcels preserved by similar means are directly north of the Marr Parcel. Applicant's ecologist raised the Marr Parcel's score by 1 point for location and landscape support and 1 point for community structure, as a result of the purchase of the conservation easement. The parcel's score for water environment was unchanged by the purchase of the conservation easement. Taking the modest gain from the purchase of the conservation easement, the ecologist applied the preservation adjustment factor of 0.60 to reduce this gain further and then applied a time lag factor of 1.0, indicative of a time lag of one year or less, and a risk factor of 1.25, indicative of the smallest incremental risk above no risk, to determine a functional gain of 2.16 units for the preservation mitigation involving the Marr Parcel. Petitioner contends that development of the Marr Parcel was unlikely, even without the conservation easement purchased by Applicant. Without detailed analysis of site characteristics and regulatory controls applicable to the Marr Parcel, it is impossible to evaluate this contention, except to note that the ecologist took very little credit for the transaction. The smallest credit is one point in all three categories; the ecologist took two points. The functional gain for this preservation mitigation, as determined by Applicant's ecologist, is supported by the record, and his analysis of this gain from the offsite preservation mitigation is accurate, provided District clarifies the ERP, which describes the Marr Parcel in detail, to require that Applicant purchase the conservation easement in the Marr Parcel as part of the required mitigation. Lastly, Applicant turned to the Upper Coastal Mitigation Bank (UCMB) to purchase 0.4 acres of forested- wetlands credit. This mitigation bank, which is administered by Earth Balance, pertains to property (UCMB Tract) that is just north of the Chassahowitzka Tract, immediately south of Homosassa Springs. A few months prior to the hearing, District permitted the UCMB for 47.64 functional gain units, for the purpose of providing mitigation bank credits to ERP applicants. District has approved UCMB for freshwater forested wetlands credits, among other types of credits. The UCMB Tract is about seven miles north of the Marr Parcel and, thus, about 40 miles north of the subject parcel. The UCMB Tract is in the large coastal basin that, according to BOR Appendix 6, includes the subject parcel and, according to District Exhibit 5, is the basin to the north of the basin that includes the subject parcel. Based on the foregoing, Applicant realized a functional gain of 0.52 units from the onsite creation and enhancement mitigation, 2.16 units from the offsite preservation mitigation from the Marr Parcel, and 0.40 units from the purchase of units from UCMB, for a total functional gain of 3.09 units. Pursuant to UMAM, the 2.70 functional loss units are exceeded by the 3.09 functional gain units, so Applicant has provided adequate mitigation. Applicant provided reasonable assurance that the proposed activity will not cause adverse impacts to the storage and conveyance capacity of surface waters. As noted above, Applicant proposes to expand the conveyance capacity of the ditch by substantially widening and deepening it, which will probably alleviate some of the longstanding flooding around the Hogan wetland. With respect to Petitioner's parcel, Applicant will place a liner on the west side of the pond, so as to prevent adverse impacts to Petitioner's parcel from base flow. Applicant will add a swale along the west side of the subject parcel to prevent adverse impacts to Petitioner's parcel from stormwater flow. The engineer's analysis in particular does not reveal flooding at the northwest corner of the Ashley Glen parcel, from where Petitioner's wetlands draw hydration. No testimony revealed whether Applicant's engineer performed pre- and post-development analysis of flows at the point at which the re-created ditch leaves the subject parcel at the DOT floodplain-mitigation site. Nothing in the record suggests that the proposed activities will cause flooding of this site, and DOT will likely perform its own analysis prior to granting Applicant a sufficient interest to dredge part of the realigned, enlarged ditch on DOT property. The proposed activities will fill 8.48 acre-feet of floodplain, but mitigate this loss with 10.02 acre-feet of excavation. Considered with the increased capacity of the drainage ditch, Applicant proposes to increase flood storage. Applicant has provided reasonable assurance that the proposed activities will not adversely impact water quality. The water-treatment components of the proposed surface water management system have been described above. Applicant provided reasonable assurance that the proposed activities will not adversely impact the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters. Some minor loss of use by small- and medium-size wildlife may be expected from the loss of 3.1 acres of Wetland C12, but the presence of State Road 54 and imminent development of the Ashley Glen parcel mean that Wetland C12 can provide no meaningful travel corridor. Degraded adjacent uplands further reduce the value of Wetland C12 as habitat for such wildlife. The created pond will provide habitat for certain birds, and the offsite mitigation will provide functional gain in terms of wildlife habitat. Changes in fish habitat from the relocation of part of the ditch and dredging of the ditch are also negligible, based on limited utilization of the present ditch and enhanced utilization potential of the new ditch in terms of a more suitable bank, which will be protected from erosion by matting, and the addition of appropriate vegetation, including emergents in the channel. For the reasons set forth above, Applicant has provided reasonable assurance that the proposed activities will not cause adverse secondary impacts to the water resources. Although the post-development wetlands are unbuffered, the secondary impacts of construction are addressed by the usual construction devices of turbidity curtains and hay bales, and the secondary impacts of the ultimate use of the Anchored Center are adequately addressed by the by the subject surface water management system, especially with respect to water quality treatment. District's senior environmental scientist disclaimed the existence of post-development secondary impacts, evidently reasoning that Wetlands B12 and C12 had already been impacted. As discussed in the Conclusions of Law, the secondary impacts are the activities closely linked to the construction of the project. In this case, the project is the surface water management system to serve the development of the Anchored Center, and the obvious secondary impact is motor vehicle traffic on the subject parcel. However, the water-quality analysis addresses this secondary impact. Subject to one exception, Applicant has provided reasonable assurance that the proposed surface water management system will perform effectively and will function as proposed and that an entity with the requisite financial, legal, and administrative capabilities will conduct the proposed activities. The exception is that District may not issue the ERP until Applicant obtains from DOT a legal instrument, in recordable form, granting Applicant and its assigns all rights necessary to construct, maintain, and operate the portion of the realigned ditch that will be located in the DOT floodplain mitigation parcel. Based on the Conclusions of Law, which necessitate the acceptance of the basin depictions in BOR Appendix 6, Applicant has provided reasonable assurance that the proposed activities will not cause adverse cumulative impacts upon wetlands and other surface waters. However, if the subject parcel were in the basin to the south of the large coastal basin, Applicant has not provided reasonable assurance that the proposed activities will not cause adverse cumulative impacts because it has not undertaken any cumulative-impact analysis. Based on the foregoing and subject to the two conditions stated above, Applicant has provided reasonable assurance that the proposed activities in, on, or over wetlands or other surface waters are not contrary to the public interest.
Recommendation It is RECOMMENDED that the Southwest Florida Water Management District issue to Win-Suncoast, Ltd., the environmental resource permit, subject to the two conditions identified above. DONE AND ENTERED this 14th day of February, 2008, in Tallahassee, Leon County, Florida. S ROBERT E. MEALE Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 14th day of February, 2008.
The Issue The issues are whether IMC Phosphates Company is entitled to an environmental resource permit for phosphate mining and reclamation on the Ona-Ft. Green extension tract, approval of its conceptual reclamation plan for the Ona-Ft. Green extension tract, and modification of its existing wetland resource permit for the Ft. Green Mine to reconfigure clay settling areas, relocate mitigation wetlands, and extend the reclamation schedule.
Findings Of Fact Parties, Phosphate Mining, and Physiography Respondent IMC Phosphates Company, a Delaware general partnership authorized to do business in Florida (IMC), has applied to Respondent Department of Environmental Protection (DEP, which shall include predecessor agencies) for an environmental resource permit (ERP) to mine phosphate rock at the Ona-Ft. Green extension tract (OFG), approval of a conceptual reclamation plan (CRP) to reclaim the mined land at OFG, and modification of a previously issued wetland resource permit (WRP) to relocate and shrink clay-settling areas (CSAs), relocate mitigation wetlands, and extend the reclamation schedule at the Ft. Green Mine, which is an existing mine that is immediately west and north of OFG. Except for the submerged bottom of Horse Creek, which is sovereign submerged land, IMC owns all of the land on which OFG will be located, except for a 1.8-acre parcel owned by Valerie Roberts in Section 16, which is described below with the other sections forming OFG. IMC is negotiating with Ms. Roberts to purchase her land, and she has authorized IMC to pursue mining permits for the entire parcel, including her land. IMC Global, Inc., owns 80 percent of IMC. IMC Phosphates MP Inc., a Delaware corporation, is the managing general partner of IMC. As a successor to International Mining and Chemical Corporation, IMC has been in business for over 100 years. IMC is the largest producer of phosphate in the world. References in this Recommended Order to phosphate mining companies include all forms of business organizations. At present, IMC is operating four phosphate mines in Florida. The largest is the Four Corners Mine, which extends into Hillsborough, Polk, Manatee, and Hardee counties and three river basins. IMC also operates the Hopewell Mine in Hillsborough County, the Kingsford Mine in Hillsborough and Polk counties, and the Ft. Green Mine. Petitioner Charlotte County is located south of Sarasota and DeSoto counties and west of Glades County. The majority of Charlotte Harbor lies within Charlotte County. Charlotte Harbor is a tidal estuary at the mouths of the Peace and Myakka rivers. An Outstanding Florida Water and an Aquatic Preserve, Charlotte Harbor provides critical habitat for a variety of species. Charlotte Harbor is now an estuary of national significance under the U.S. National Estuary Program. Directly or indirectly, Charlotte Harbor supports 124,000 jobs and generates $6.8 billion in sales annually. To protect this unique natural resource, Charlotte County has adopted a local government comprehensive plan directing residential densities away from Charlotte Harbor. Charlotte County has also expended over $100 million in sanitary sewer capital expenditures for, among other things, the protection of Charlotte Harbor, such as by replacing private residential septic tanks with central sewer. Charlotte County's opposition to phosphate mining and reclamation in the Peace River basin is based on concerns about reduced river flows, reduced abundance and diversity of fish species, the loss of wetlands and first-order streams, and degraded water quality. Petitioner Peace River/Manasota Regional Water Supply Authority (Authority) is an agency authorized by Section 373.196(2), Florida Statutes, and created by interlocal agreement among Charlotte, Sarasota, DeSoto, and Manatee counties. The purpose of the Authority is to supply potable water to several suppliers in southwest Florida. Relying exclusively on the Peace River as its source of raw water, the Authority withdraws water from the Peace River two miles downstream of the point that Horse Creek empties into the Peace River. This point is about midway between Arcadia and Charlotte Harbor. As discussed below, the Authority's permit to withdraw water from the Peace River is dependent upon flows at a point upstream of the confluence of Horse Creek and the Peace River. The Authority's current water use permit expires in 2016. From its water treatment plant, which is located near the withdrawal point, the Authority pumps finished water to Charlotte, Sarasota, and DeSoto counties and the City of North Port. Approximately 250,000 persons rely on these suppliers, and, thus, the Authority, for their potable water. At present, the Authority is obligated to supply 18 million gallons per day (mgd), but anticipates demand to increase to 32 mgd by 2015. Petitioner Sarasota County (Sarasota County) owns and operates a water utility system, which currently supplies 24 mgd of potable water to 125,000 persons. Sarasota County obtains potable water from its wellfields, Manatee County, and the Authority, from which it may take up to 3.6 mgd. By 2017, Sarasota County plans to take 13.7 mgd of potable water from the Authority, partly to offset anticipated reductions in the amount of potable water presently being supplied by Manatee County. By 2017, the Authority will supply over half of Sarasota County's potable water. Sarasota County also shares Charlotte County's concerns about the overall environmental integrity of Charlotte Harbor, a small part of which is in Sarasota County. Intervenor Lee County (Lee County) is immediately south of Charlotte County. Nearly half of Charlotte Harbor lies within Lee County. Tourism produced an estimated $1.8 billion to Lee County's economy in 2002. Tourists are attracted to Lee County in part due to the high quality of Charlotte Harbor and its unique chain of barrier islands, passes, sounds, and bays that are integral to local fishing and boating. Lee County shares Charlotte County's concerns about the overall environmental integrity of Charlotte Harbor. Lee County is concerned about, among other things, degraded water quality from the discharge of turbid water, increased pollutant loads to the Peace River and Charlotte Harbor, adversely affected freshwater flows in the Peace River, and the consequences of the phosphate mining industry's inability to restore secondary tributaries, which provide base flow and environmental benefits to Charlotte Harbor. Petitioner Alan R. Behrens (Behrens) resides in Wimauma, Florida, which is in Hillsborough County. He has owned two five-acre tracts along Horse Creek since 1985 and owns a 2.5-acre lot in DeSoto County that fronts Horse Creek for 100-200 feet. The Horse Creek property is 10-15 miles downstream from OFG. Behrens has canoed the entire main stem of Horse Creek from the Peace River to OFG. On May 9, 2004, Behrens canoed up Stream 4w, which is a tributary of Horse Creek on OFG and is described in detail below. Behrens is a founder of Petitioner DeSoto Citizens Against Pollution, Inc. (DCAP), which was incorporated in 1990 as a Florida not-for-profit corporation and has operated in that status continuously since that time. DCAP's purpose is to protect fish, wildlife, and air and water resources; promote public health and safety; increase public awareness of potential environmental hazards; and discourage activities that may be adverse to public health or the environment. DCAP has 52 members, of whom 27 reside in Hardee County, 23 reside in DeSoto County, and two reside in Sarasota County. A substantial number of DCAP's members use Horse Creek for swimming, boating, canoeing, and fossil hunting. At least nine DCAP members own property abutting Horse Creek. Behrens and many DCAP members use wells on their property for potable water. Behrens and DCAP members are concerned that the clay- settling areas described below will increase flooding, the project will adverse affect the timing and volume of the flow and degrade the water quality of Horse Creek, the project will destroy wildlife habitat that--even if reclaimed--will be lost for many years, and the project will cause spills that will destroy fish and wildlife and adversely affect the ability of Behrens and DCAP to enjoy Horse Creek. OFG is in northwest Hardee County, about one-half mile east of the Manatee County line. OFG is about six miles south- southeast of the Four Corners, where Hardee, Manatee, Polk, and Hillsborough counties meet. OFG is about 35 miles east of Bradenton, 12 miles west of Wauchula, several miles south of State Road 62, and 2000 feet north of State Road 64. OFG represents the southernmost extent of phosphate mining in the Peace River basin to date. A nonrenewable resource for which no synthetic substitutes exist, phosphate is an essential nutrient and a major component of manufactured fertilizer. Less important uses of phosphate are for animal feed, soft drinks, and cosmetics. Mining phosphate rock and processing it into phosphoric acid or phosphorus make possible high-yield agriculture, which, by producing more food crop on less land, may reduce worldwide pressure to convert native habitat to improved agricultural land uses. Phosphate is available in limited quantities. Three- quarters of the recoverable phosphate rock in the United States is found in Florida, mostly in discrete deposits ranging from north-central Florida to Charlotte Harbor. Ten to fifteen million years ago, when peninsular Florida was submerged marine bottom, dead marine organisms accumulated as bone and shell on the ocean floor. These accumulations formed the Bone Valley Formation, which, as the seas withdrew and the peninsula emerged, occupies the lower part of the surficial aquifer at the site of OFG. Briefly, the main elements of the proposed activities in these cases, roughly in the order in which they will take place, are relocating wildlife; constructing a ditch and berm system around the area to be mined; removing topsoil from certain donor areas; removing the overburden and depositing it in rows of spoil within the mine cut; removing the underlying phosphate matrix and slurrying it to a nearby beneficiation plant at the Ft. Green Mine for processing to separate the phosphate rock from the sand and clay tailings; slurrying the clay tailings from the beneficiation plant to two CSAs at the southern end of the Ft. Green Mine; slurrying the sand tailings from the beneficiation plant back to the mine cut to backfill the excavation; applying topsoil to certain areas or green manuring areas for which topsoil is unavailable; applying muck to certain areas; contouring the reclaimed land to replicate pre-mining topography; analyzing the post-reclamation hydrology; reclaiming wetlands, streams, and uplands on the reclaimed landscape of OFG; maintaining and monitoring the reclaimed wetlands, streams, and uplands until DEP releases IMC from its ongoing reclamation obligations; correcting any problems in reclaimed areas; and removing the ditch and berm system and reconnecting the reclaimed mined area to the areas adjoining it. In the Findings of Fact, this Recommended Order uses "reclaim" to describe the process by which, post-mining, IMC and its reclamation scientists will construct wetlands, other surface waters, and wetlands at OFG. Likewise, in the Findings of Fact, this Recommended Order uses reclamation and mitigation interchangeably. In the Conclusions of Law, this Recommended Order discusses distinctions in these terms. IMC plans to use multiple draglines to dig a series of long, linear trenches in the mined areas of OFG. Each dragline will first remove overburden and place it in piles parallel to the trench being excavated. After removing the overburden, each dragline will remove the phosphate matrix, which consists of phosphate rock, sand, and clay, and deposit it in shallow depressions. Adding water from the mine recirculation system to the phosphate matrix, IMC will slurry the phosphate matrix to the Ft. Green beneficiation plant, which is about 12 miles from OFG. At the beneficiation plant, the phosphate rock will be separated from the sand and clay tailings, again using water from the mine recirculation system. After recovering the phosphate rock, IMC will slurry the sand tailings, which do not retain water, from the Ft. Green beneficiation plant to OFG for backfilling into the mined trenches with the overburden. Not used in the reclamation at OFG, the clay tailings, which retain water for an extensive period of time, will be slurried to the CSAs O-1 and O-2 on the Ft. Green Mine. CSAs O- 1 and O-2 are the subject of the WRP, which is discussed below. The volume of the clay leaving the beneficiation plant is greater than the clay in situ, pre-mining, because the slurrying process has saturated the clay. The CSAs provide a place to store the saturated clay while it drains and decreases in volume. The clay-settling process takes a long time, extended by IMC's intention to fill the CSAs by stages to make the most efficient use of the areas designated for the settling of clay. By stage-filling the CSAs, IMC will initially install the clay to a considerable height, using an embankment of approximately 50-60 feet. The water that separates from the clay will then drain across the sloped CSA until it enters the mine recirculation system for reuse. The remaining clay will dry and consolidate. After refilling each CSA approximately three times over about ten years, IMC will allow the clay to settle and consolidate a final time. When the clay has consolidated sufficiently to support agricultural equipment, IMC will regrade the area, reduce the side slopes, and remove the embankments, leaving the CSAs at a finished elevation 20-25 feet above the surrounding grade. Given the ongoing nature of IMC's phosphate mining operations, it is likely that some sand and clay tailings from OFG will go elsewhere, rather than return to the OFG mine cuts and CSAs O-1 and O-2, and that some sand and clay tailings from non-OFG mining operations will go to the OFG mine cuts and CSAs O-1 and O-2. However, these facts are irrelevant to the issues raised in these cases, except for consideration of IMC's sand- tailings budget, which is discussed below. Phosphate mining and reclamation practices have changed dramatically in the past 40 years. Although mining operations and reclamation practices are discussed below in detail, one development in mining and one development in reclamation bear emphasis due to the resulting reductions in water losses to the drainage basin. As explained below, mining operations are dependent upon large volumes of water, which flow through the mine recirculation system. Before 1963, phosphate mining pumped roughly 3000 gallons of water for each ton of mined phosphate rock. By the mid-1970s through 1990, the industry had reduced its groundwater consumption to 1500 gallons per ton of mined rock. From 1991 to 1999, the industry again reduced its groundwater consumption from 1200 gallons per ton to 650 gallons per ton, partly by achieving a 97 percent rate of water- recycling in the mine recirculation system. During roughly the same period, phosphate reclamation activities have expanded considerably. Prior to July 1, 1975, reclamation of mined land was voluntary, encouraged only by the availability of state funds to offset reclamation costs. Today, post-mining reclamation is required by law. As a consequence, post-mining reclamation 30 years ago was relatively modest in scope and intensity. One important development in reclamation practices is the phosphate mining industry's transition from early reclamation techniques that relied on relatively inexpensive contouring of the overburden that remained in the mine cuts following the extraction of the phosphate ore. These reclamation practices--aptly called Land-and-Lakes reclamation-- yielded post-reclamation excavations, such as reclaimed lakes or deep marshes, that, compared to pre-mining conditions, retained considerable volumes of surface water. The resulting increase in surface water area, compared to pre-mining surface water area, meant substantial loss of water from the drainage basin due to increased evapotranspiration. More recent reclamation practices, such as those proposed for OFG, feature more extensive backfilling of the mine cuts with tailings to restore pre-mining topography. The result is that less water is lost to evapotranspiration by retention in newly created lakes and deep marshes and more is timely held and passed by the natural drainage conveyances through detention, attenuation, runoff, and base flow--eventually entering the main basin river in volumes, rates, and times (relative to storm events) comparable to pre-mining conditions. Located near the western divide of the Peace River basin, OFG is near a topographical high point marking the divides among five drainage basins. From north to south, the four other basins are drained by the Alafia River, Little Manatee River, Manatee River, and Myakka River. OFG is located toward the bottom of an escarpment where the Polk Uplands descends into the DeSoto Plain. OFG is located almost entirely within a portion of the Horse Creek basin or sub-basin within the Peace River basin. This Recommended Order shall refer to the drainage basins that form the larger Peace River basin as sub-basins. A small portion of the western edge of OFG is within the West Fork Horse Creek (West Fork) sub-basin, and a small portion of the eastern edge of OFG is within the Brushy Creek sub-basin. OFG is toward the upper end of the Horse Creek sub-basin. The West Fork and Brushy Creek sub-basins within OFG contain no streams or stream segments and only, between them, about a half dozen wetlands of one-half acre in size or greater. Obviously, as separate sub-basins, these two areas on OFG are relatively far from Horse Creek. West Fork joins Horse Creek a couple of hundred feet south of OFG and just north of State Road 64. Brushy Creek joins Horse Creek six miles southeast of OFG. Horse Creek joins the Peace River at Ft. Ogden, about 40 miles south of OFG and 15 miles northeast of the mouth of the Peace River at Charlotte Harbor. The Peace River basin comprises about 2350 square miles and extends from its headwater lakes in north Polk County to Charlotte Harbor. By comparison, the Horse Creek sub-basin comprises about 241 square miles, or roughly ten percent of the Peace River basin. At Charlotte Harbor, the average flow of the Peace River is about 1700 cubic feet per second (cfs). By comparison, Horse Creek, at its confluence with the Peace River, flows at an average rate of about 170 cfs--again ten percent of the average rate of flow of the Peace River. West Fork, at its confluence with Horse Creek, flows at an average rate of about 10 cfs. The largest tributary on OFG flows at an average rate of about 0.75 cfs. Forming a little south of Four Corners, Horse Creek is one of five major tributaries of the Peace River. An ecological backbone of this region of Florida, Horse Creek is the only long-term, reliable flowing water system between the Manatee River on the west and Peace River on the east. OFG occupies the upper reaches of Horse Creek. Horse Creek is in good condition, notwithstanding 100 years of nearby cattle ranching. Most of Horse Creek is Class III waters, although a segment near the Peace River is Class I waters. Horse Creek is a moderately incised stream at OFG, especially over its southern two-thirds running through the mine site. Over the little more than three miles that Horse Creek flows through OFG, the streambed drops from nearly 120 feet National Geodetic Vertical Datum (NGVD) at the north end to about 75 feet NGVD at the south end. Within OFG, the valley that Horse Creek occupies is also relatively well-defined. The northern half of the streambed of Horse Creek within OFG is mostly around 100 feet NGVD. The highest adjacent elevations on OFG are about 120 feet NGVD. At least partly for this reason, most of the tributary streams, except in the flat northern portion of OFG, are also well-incised. OFG extends about 4 1/2 miles north to south, and ranges from 2/3 to 2 1/2 miles from east to west, for a total area of about 6 1/2 square miles. Lying entirely within Township 34 South, Range 23 East, OFG, from its northernmost border, occupies three sections, which are, from north to south: Sections 4, 9, and 16. Immediately west of the southern half of Section 9, OFG occupies most of the southern half of Section 8. Immediately west of Section 16, OFG occupies Section 17, as well as, immediately south of Section 17, all of Section 20 and most of the northern half of Section 29. OFG also extends to parts of four other sections: Sections 10 and 15 east of Sections 9 and 16, respectively, and Sections 18 and 19, west of Sections 17 and 20, respectively. The existing surface waters and nearly all of the existing wetlands are on the two columns of sections running north and south: on the east, Sections 4, 9, and 16 and, on the west, Sections 17, 20, the south part of Section 8, and the north part of Section 29. The northernmost extent of OFG, which consists of Section 4 and the north half of Section 9, is known as the Panhandle. Horse Creek enters OFG at the southwest corner of the Panhandle, at a point midway along the west border of Section 9. The stream flows south through the approximate center of OFG for about 1 1/2 miles until it leaves OFG for a very short distance at the southwest corner of Section 16, as it crosses a corner of property owned by the Carlton-Smith family (Carlton cutout). Horse Creek re-enters OFG at the northeast corner of Section 20 and runs just inside the eastern border of Section 20 and the portion of Section 29 within OFG. Horse Creek leaves OFG near the midpoint of the east border of Section 29. Numerous tributary streams enter Horse Creek within OFG, from the east and west sides of the creek. IMC and DEP have assigned to each of these streams or stream segments a number, followed by a letter to indicate if the stream or stream segment enters Horse Creek from the east or west. To the west of Horse Creek, proceeding from south to north, the streams are 0w, 1w, 2w, 3w, 4w, 5w, 6w, 7w, 8w, and 9w. To the east of Horse Creek, proceeding from south to north, the streams are 12e, 11e, 10e, 5e, 9e, 4e, 8e, 7e, 6e, 2e, 3e, and the Stream 1e series, consisting of Streams (sometimes referred to as stream segments) 1ee, 1ed, 1ec, 1eb, and 1ef. All of the streams join Horse Creek on OFG except Stream 2e, which joins Horse Creek a few hundred feet upstream of the point at which Horse Creek enters OFG, and Stream 7w, which empties into a backwater swamp (G185/G186) that, in turn, empties into either Horse Creek or the lower end of Stream 6w immediately before it empties into Horse Creek. The alphanumeric designation of the backwater swamp in the preceding paragraph is based on the Map F-2 series, which assign such a designation to each existing wetland community and then identifies the wetland community. For example, the backwater swamp consists of a wet prairie (G185) surrounded by a mixed wetland hardwoods (G186). If a wetland consists of more than one wetland community, this Recommended Order will refer to it either as a wetland complex with its lowest-numbered wetland community--here, wetland complex G185--or the combination of wetland communities--here, G185/G186. Reclaimed wetlands are identified by Figure 13A5-1, which assigns each wetland an alphanumeric designation and identifies its community. The letter indicates if the reclaimed wetland is east ("E") or west ("W") of Horse Creek. Table 13A5-1 2AI identifies each reclaimed wetland by its alphanumeric designation, community, acreage, and status as connected, isolated, or isolated and ephemeral. Table 13A5-1 2AI identifies 110 wetlands to be reclaimed. The largest wetland is E003, which is a 23.8-acre mixed wetland hardwoods that constitutes the riparian wetland of the Stream 1e series. The next largest is W003, which is a 20.7-acre wet prairie at the headwaters of Stream 9w. Only three other reclaimed wetlands will be at least ten acres: E018, an 11.3-acre wet prairie fringe on the east side of Section 4; E020, an 11.5-acre freshwater marsh at the center of E018; and W039, an 11.2-acre bay swamp at the headwater of Stream 1w. Thirteen reclaimed wetlands are at least five acres, but less than ten acres, and 30 reclaimed wetlands are less than one acre. Table 13A5-1 2AI identifies 44 reclaimed ephemeral wetlands totaling 101 acres. Reclaimed uplands are identified by Map I-2. Although the scales of Map I-2 (one inch equals about 820.5 feet) and the Map F-2 series (one inch equals about 833.3 feet) are larger than the scales of nearly all of the other maps and figures in these cases, acreages derived from these maps for uplands and existing wetlands are very rough approximations and do not approach in accuracy the acreages derived from Table 13A5-1 2AI for reclaimed wetlands. These maps and figures omit one stream segment to be reclaimed. IMC and DEP restricted the designation scheme to streams and stream segments that had once been natural systems, thus excluding artificially created waterways, such as those created by agricultural ditches cut into swales to drain upslope wetlands and uplands. During the hearing, older aerial photographs revealed that, under this scheme, the parties had omitted one stream segment, which they designated Stream 3e?. Stream 3e? is northeast of Stream 3e, from which it is separated by a wetland (G133/G134/G135/G136). Besides the streams, two other areas within OFG require early identification due to their prominence in these cases. The northerly area is the Heart-Shaped Wetland (G138/G139/G140/G141/G143/G143A), which is the large wetland in Section 4 into which the Streams 1e series and Stream 3e empty. The other area of heightened importance is in the center of OFG in Sections 17 and 16 and is called the East Lobe, Central Lobe, and West Lobe or, collectively, the Lobes. Dominated by large bayhead headwaters (West Lobe--G197; Central Lobe--G179; East Lobe--G178), the Lobes and the streams connecting them to Horse Creek are entirely within the no-mine area. The West and Central Lobes connect to the west bank of Horse Creek by Streams 6w and 8w, respectively. The East Lobe connects to the east bank of Horse Creek by Stream 9e. The no-mine areas of the West and East Lobes are much larger than the no-mine area of the Central Lobe, and the East Lobe contains a large area of uplands extending east of, and supporting, the large bayhead. Most OFG wetlands are connected or contiguous, and many of these wetlands are riparian wetlands within the 100-year floodplain of Horse Creek or a floodplain of one of the tributaries of Horse Creek. (As used in this Recommended Order, the floodplain of Horse Creek runs roughly parallel to the banks of Horse Creek and excludes any portion of the floodplain more directly associated with Horse Creek's tributaries or their connected wetlands.) All or nearly all of the isolated wetlands on OFG are ephemeral and permanent, except in very low rainfall periods. The scale of mining is large. The phosphate matrix, which contains the phosphate rock, is overlaid by a layer of sand and clay overburden, which, with topsoil, is projected to range from 20-40 feet, averaging 27 feet, in thickness. The phosphate matrix is projected to range from 25-35 feet, averaging closer to 25 feet, in thickness, although as much as four feet of the matrix may consist of interburden, such as sand, clay, limerock, or gravelly materials. Thus, mining will remove, on average, 52 feet of the earth's surface. In no area will mining extend deeper than the top of the limey clay bed, which is the confining layer dividing the surficial aquifer from the intermediate aquifer, of which the limey clay bed is a part. (Technically, the matrix is part of the confining layer, but it provides so little confinement that it is easier to consider it part of the surficial aquifer. A consequence of this fact is that the removal of the matrix does not increase the rate of deep recharge, at least where the matrix is replaced with cast overburden.) At OFG, the thickness of the surficial aquifer varies from 65-70 feet at the basin divide to 50 feet or less at the riparian wetlands and averages 55 feet. Beneath the intermediate aquifer, which is about 300 feet thick at OFG, lies the Floridan Aquifer. IMC projects OFG to yield 24 million tons of phosphate rock, 26 million tons of clay tailings, and 68 million tons of sand tailings. IMC projects that the no-mine areas, which are discussed below, will result in five million tons of phosphate rock reserves remaining in the ground post-mining. The scale of the environmental impact of mining is correspondingly large. Mining removes all flora and fauna, all the topography, soils, and upper geology, in the path of the electric dragline, which, as long as a football field (including one end zone), removes the uplands, wetlands, streams, and soils covering the matrix. At the depths at which mining will take place, IMC will be removing the entire surficial aquifer. Applications, ERP, CRP Approval, and WRP Modification Preliminary Matters These cases involve permits and an approval of the phosphate mining and reclamation processes. These cases do not involve the processes by which IMC transforms phosphate into end products, mostly fertilizer. With one exception, these cases do not involve the processes by which IMC separates the phosphate ore from the sand and clay (i.e., the beneficiation process). (The exception is that IMC is seeking to extend by ten years the life of the Ft. Green beneficiation plant to separate the phosphate from the matrix slurried from OFG.) These other post- mining processes, which are separately permitted, are not directly involved in these cases because IMC will slurry the phosphate matrix mined from OFG to the existing Ft. Green beneficiation plant, which is already permitted and operating. Even though the WRP modification will authorize the relocating of already-permitted CSAs at the Ft. Green Mine, the WRP modification will not authorize the design or construction of the embankments that retain the water within these CSAs while they are essentially clay ponds. DEP will separately permit the construction and operation of CSAs O-1 and O-2. Application and Proposed Agency Action On April 24, 2000, IMC filed a Consolidated Development Application for an ERP to mine phosphate from the proposed 20,675-acre Ona Mine, approval of the CRP for the Ona Mine following the completion of mining, and modification to the existing WRP for the Ft. Green Mine to install three CSAs in the area of the Ft. Green Mine immediately west of the Ona Mine and extend the life of the Ft. Green beneficiation plant by ten years to process the matrix from the Ona Mine. On January 17, 2003, DEP issued an Intent to Issue an ERP and proposed approval of the CRP. Petitioners in several of the above-styled cases challenged this proposed agency action, and the parties embarked upon an energetic prehearing process of preparation, including extensive discovery and prehearing telephone conferences with the Administrative Law Judge, in anticipation of a final hearing in the fall of 2003. IMC and DEP entered into a Team Permitting Agreement, pursuant to 1996 legislation creating the concept of Ecosystem Management. The Team Permitting Agreement incorporates the concept of "net ecosystem benefit," but, on its face, is not binding on IMC. The obvious purpose of the Team Permitting Agreement was to induce the permitting agencies (i.e., DEP, Florida Fish and Wildlife Conservation Commission (FWC), Southwest Florida Water Management District (SWFWMD), two regional planning councils, the Florida Department of Community Affairs, the Florida Department of Transportation (DOT), Hardee County, DeSoto County, and the U.S. Army Corps of Engineers) to use a common development application and coordinate, to the greatest practical extent, their respective reviews of the proposed activities of IMC. Three weeks prior to the start of the final hearing, on September 15, 2003, DEP issued the Final Order in Charlotte County et al. v. IMC Phosphates Company and Department of Environmental Protection, 2003 WL 21801924, 4 ER FALR 42 (Altman Final Order). The Altman Final Order denies IMC's application for a WRP/ERP and disapproves IMC's proposed CRP for the Altman tract, which is a short distance northwest of OFG. Although the final and recommended orders are detailed and complex, the Altman Final Order essentially concludes that IMC's CRP was inconsistent with applicable law because its basic reclamation concept was "to replace an existing system of high-quality wetlands . . . with a deep freshwater marsh." On the same date of the Altman Final Order, DEP Deputy Secretary Allan Bedwell ordered DEP's Bureau of Mine Reclamation (BMR) to re-examine IMC's application for an ERP and request for approval of the CRP for the Ona Mine to assure consistency between the proposed agency action approving the ERP, CRP, and WRP modification and the Altman Final Order. The Bedwell memorandum specifically directs BMR to verify IMC's classification and characterization of the extent and quality of wetlands on the site; verify that IMC's proposed reclamation activities, including its proposed control of nuisance or exotic species, "maintain or improve the water quality and function" of the biological systems present at the site prior to mining; and verify that IMC meets the financial assurance requirements of law. The memorandum concludes by directing BMR to modify any proposed agency action, if necessary. By memorandum dated January 5, 2004, Richard Cantrell and Janet Llewellyn, Deputy Directors of DEP's Division of Water Management Resources, responded to the memorandum from Deputy Secretary Bedwell. With respect to IMC's classification and characterization of wetlands, the January 5 memorandum states that DEP staff had conducted additional review of available aerial photographs, reviewed field notes from previous field inspections, conducted new field inspections, and received comments from IMC and Charlotte County. To describe better onsite habitats and communities, DEP staff had also revised the DOT Florida Land Use, Cover, and Forms Classification System (FLUCFCS) for use at OFG. The FLUCFCS codes are a three-digit numbering system to classify and identify individual vegetative communities or land uses. With respect to the ability of the proposed reclamation to maintain or improve the water quality and function of biological systems, the January 5 memorandum states that Deputy Directors Cantrell and Llewellyn had recommended to IMC that it consider phasing the mining on Ona, so that it could apply its experience in reclaiming OFG to the remainder of the original Ona Mine; preserving additional onsite natural stream channels and proposing more detailed reclamation plans for mined streams; preserving additional onsite bay-dominated wetland systems; providing additional assurances that upgradient sand/scrub areas will continue to support hydrologically, through seepage, preserved and restored bayheads; providing a plan to control nuisance and exotic species in the uplands, which, if infested, would degrade adjacent wetlands post-mining; and providing assurances that groundwater flows to Horse Creek and its preserved tributaries will be maintained during mining and post-reclamation. With respect to financial responsibility, the January 5 memorandum states that Deputy Directors Cantrell and Llewellyn had advised IMC that it must provide its financial responsibility for the mitigation of all wetlands authorized to be mined, rather than providing its financial responsibility on a phased basis, as it had previously proposed. On January 30, 2004, IMC filed a voluminous amendment to the Consolidated Development Application in a package known as the January submittal. The most evident change made by the January submittal is the reduction of the Ona Mine to OFG, which was the westernmost one-fifth of the original Ona Mine. The introduction to the January submittal highlights the changes that IMC made to the original application. The introduction explains that IMC has employed a revised mapping protocol to ensure that all waters of the State, including wetlands delineated by Florida Administrative Code Rule 62-340.300 and other surface waters delineated by Florida Administrative Code Rule 62-340.600, are classified as wetlands or water, pursuant to the modified FLUCFCS codes. Rejecting the nomenclature of the January 5 memorandum regarding the phasing of mining at the Ona site, the introduction to the January submittal identifies OFG as a 4197- acre, "free-standing" mining tract, not in any way "coupled to or dependent on the development of the remainder of the Ona Tract," from which it was taken. The introduction explains that "free-standing" means that OFG is a "complete mining, reclamation, and mitigation proposal" and that the OFG ERP will be "for a single-phase project." The introduction to the January submittal notes that IMC has enlarged the no-mine area to include "nearly all of the natural stream channel tributaries to Horse Creek present in the portions of the Parcel that have not been converted to improved pasture." The amendments thus avoid disturbing four additional natural stream segments. The introduction explains that IMC considered a series of factors in determining whether to mine a stream segment: "stream segments length, the existing land cover adjacent to the stream and its watershed, the complexity of the channel geometry[,] and historical agricultural impacts." The introduction adds that IMC has added a "state-of-the-art" stream restoration plan for mined natural streams. The introduction to the January submittal states that IMC responded in two ways to the suggestions about bay swamps in the January 5 memorandum. First, IMC modified the conventional mapping protocol for bay swamps. Rather than require that the canopy of the subject community be dominated by loblolly bay, sweetbay, red bay, and swamp bay trees, as prescribed by the FLUCFCS codes, IMC designated as bayheads "depressional, seepage-driven forested headwater wetlands, surrounded, at least in part, by moderately to well drained upland soils, with a defined outlet connection to waterways such that the 'bay head' soils are perennially moist but infrequently inundated." This new mapping protocol did not require the presence of bay trees in the canopy. Second, IMC enlarged the no-mine areas to avoid disturbing all but nine percent of existing bay swamps at OFG, totaling less than ten acres. IMC based its mine/no-mine decisions for particular bayheads on analysis of the hydrological, water quality, and relative functional value provided by these communities to fish and wildlife. The introduction concludes that IMC has also developed detailed plans to mitigate for the few mined bayheads. The introduction to the January submittal states that IMC has added new protections for the sand/scrub areas upgradient from, and providing seepage into, the bayheads in the West and East Lobes. First, IMC will avoid mining certain of these areas, presumably adjacent to the East Lobe. Second, IMC will employ special mining techniques and schedules to reclaim these upland areas quickly and effectively. Additionally, the introduction notes that IMC is proposing to: align the dragline "cut patterns" such that the spoil piles will be aligned with the groundwater seepage path where feasible or, where not feasible, to grade the spoil piles prior to backfilling the mine voids with sand so as not to impede post- reclamation groundwater flow; accelerate the sand backfilling schedule of the mined voids adjacent to avoided "bay heads" to one year following mining disturbance; and create a reclaimed stratigraphy that results in post-reclamation seasonal high and normal water table elevations and hydraulic conductivities in the seepage slopes that will provide the hydrologic support required to sustain these communities. As explained in a later section of the introduction to the January submittal, "stratigraphy" refers to the soil layers or horizons, which are described in detail below. The introduction states: "The majority of the overburden will be placed at depths below the surface soil horizons. As a result, the surface soils will either be comprised of translocated surface soils or a loose mixture of 'green manure organics,' overburden, and sand that both resembles the native soils and provides a suitable growing medium for the targeted vegetative communities." The introduction adds that, at final grade, sand tailings will always overlie overburden by at least 15 inches. The introduction asserts that the overburden underlying the backfilled sand tailings will be "comprised of and have properties which are similar to B horizons (subsoils) and C horizons (substratums) of native Florida soils." The introduction to the January submittal identifies a Habitat Management Plan (also known as the Site Habitat Management Plan) that, with the Conservation Easement and Easement Management Plan discussed below, will guide the revegetation of upland natural systems, control nuisance and exotic species in uplands, and manage all potential listed species that may be present, whether or not observed, in areas to be mined. The introduction also mentions habitat enhancements "to relocate Florida mice" and to manage gopher tortoises. The introduction concludes with IMC's undertaking to ensure that exotic/nuisance cover does not exceed ten percent in all reclaimed wetlands and to provide a 300-foot buffer around wetlands where cogongrass--a highly invasive nuisance exotic described in more detail below--will not exceed five percent coverage. The introduction to the January submittal notes that the proposed activities will maintain groundwater flows to Horse Creek and tributaries in the no-mine areas during mining and post-reclamation. The introduction again mentions IMC's commitment, where feasible, to align spoil piles with groundwater flow and, where not feasible, grade spoil piles before backfilling so as to add a thicker band of sand to these areas. The introduction also cites the ditch and berm system as a means to maintain groundwater seepage during mining. The introduction to the January submittal states that IMC will meet its financial-responsibility requirements for the entire cost of wetland-mitigation at OFG. The January submittal contains a discussion of community-mapping protocol. IMC's methodology for mapping bay swamps is discussed above. The most common vegetative communities and land uses are described in the following paragraphs. Improved pasture is actively grazed pasture dominated by cultivated pasture grasses, such as bahiagrass, but may support native grasses. Improved pasture may contain sporadic shrubs and trees. Pine flatwoods occupy flat topography on relatively poorly drained, acidic soils low in nutrients. The overstory is discontinuous with areas of dense, species-rich undergrowth or groundcover. Longleaf pine and slash pine predominate. Pine flatwoods require frequent fires, which are carried by grasses, and the pines' thick bark helps prevent fire damage to the trees. At one time, about three-quarters of Florida was covered by pine flatwoods. Palmetto prairies typically represent the undergrowth of pine flatwoods. Once the trees are removed, such as by timbering, the resulting community is a palmetto prairie, which is characterized by an often-dense cover of saw palmettos with no or scattered pines or oaks. Occupying dry, sandy, well-drained sites, sand live oak communities feature a predominance of sand live oaks and often succeed in relatively well-drained pine flatwoods after the removal of the pines, conversion to palmetto prairie, and suppression of fire. Sand live oak may also occupy xeric oak communities. Moister soils may support live oak communities, which also may succeed pine flatwoods after the removal of the pines, conversion to palmetto prairie, and suppression of fire. Hardwood-conifer mixed is a blend of hardwoods and pines with trees of both categories forming one-third to two- thirds of the cover. Hardwoods are often laurel oak and live oak, and pines are often slash pine, longleaf pine, and sand pine. The midstory is typically occupied by younger individuals of the overstory communities and wax myrtle. If sufficient light reaches the ground, groundcover may exist. Temperate hardwoods are often a forested uplands transition to a wetland. Temperate hardwoods are usually dominated by laurel oak, but other canopy species may include cabbage palm, slash pine, live oak, and water oak. Mixed hardwoods is a similar community, except that water oak is predominant in the canopy. Two of the three most prevalent forested wetlands on OFG are bay swamps, which have been discussed, and hydric oak forest, which, because of their location in the Horse Creek floodplain, will not be mined. At DEP's request, IMC remapped some of the floodplain that was uplands (and already in the no- mine area) to hydric oak forest. The other prevalent forested wetlands on OFG is mixed wetland hardwoods, which consists of a variety of hardwood species, such as the canopy species of red maple, laurel oak, live oak, sweetbay, and American elm. Slash pines may occur, but may not constitute more than one-third of the canopy. Suitable shrubs include primrose willow, wax myrtle, and buttonbush. Ferns are often present as groundcover. Often immediately downgradient of bay swamps, mixed wetland hardwoods are typically in the hydric floodplains of small streams. Transitioning between uplands, such as palmetto prairies, and the wetter soils hosting bay swamps and mixed wetland hardwoods, wetland forested mixed communities (also known as wetland mixed hardwood-coniferous) often occupy wet prairies from which fire has been suppressed for at least 20 years and, as such, "are largely or entirely an artifact of land use practices during the past sixty years or so that have allowed the conversion of wet prairies . . . to this cover type." The canopy of wetland forested mixed is slash pine, laurel oaks, live oaks, and other hardwoods that tolerate or prefer wetter soils. Wet prairies are a dense, species-rich herbaceous wetland, usually dominated by grasses. Wet prairies occupy soil that is frequently wet, but only briefly and shallowly inundated. Similar to freshwater marshes, but with shorter hydroperiods, wet prairies often fringe marshes, and their border will shift in accordance with rainfall levels over several years. Freshwater marshes consist predominantly of emergent aquatic herbs growing in shallow ponds or sloughs. Typical marsh herbs include pickerelweed, maidencane, and beakrushes. Hydroperiod and water depth drive the presence of species in different locations within a freshwater marsh. Marshes may be isolated or may occupy a slough in which their water flow is unidirectional. Heavily grazed or drained marshes may suffer dominance of primrose willow. Abundant softweed may indicate ditching, and soft rush, which cattle avoid, may indicate heavy grazing. Shrub marshes succeed stillwater freshwater marshes from which fire has been excluded. Shrub marshes form after agricultural ditching or culverted fill-road building. Common shrub species include buttonbush, southern willow, and primrose willow. Hydric trees, such as red maple and swamp tupelo, may occupy the edges of shrub marshes. IMC supplemented the January submittal with submittals dated February 26 and 27, 2004. Collectively, these are known as the February submittal. The February submittal is much less- extensive than the January submittal, although it includes substantive changes. After examining the January and February submittals, on February 27, 2004, DEP issued a Revised Notice of Intent to Issue an ERP for OFG, approved a revised CRP for OFG, and issued a revised WRP modification for the Ft. Green Mine, which now authorizes two CSAs--O-1 and O-2--that have the effect of relocating the previously approved CSAs farther away from Horse Creek and reducing their size due to the reduced scale of OFG as compared to the original Ona Mine; reconfiguring certain mitigation wetlands, necessitated by the relocation of CSAs O-1 and O-2, with a net addition of 2.7 acres of herbaceous wetland area; and changing the reclamation schedule to conform to the already-approved CRP for the Ft. Green Mine. IMC supplemented the January and February submittals with submittals dated March 30, April 18, and April 21, 2004. These submittals, which are known as the Composite submittal, are much less-extensive than the February submittal. DEP expressly incorporated the February submittal into the ERP, CRP approval, and WRP modification dated February 27, 2004. DEP has impliedly incorporated the changes in the Composite submittal into the ERP, CRP approval, and WRP modification. Thus, this Recommended Order uses the latest version of these documents when discussing the relevant permit or approval. The March 30, 2004, submittal updates the following maps, figures, and tables: Map F-2 (to correct legend), Map I-2 (to correct the post-reclamation vegetation in the vicinity of Streams 3e, 1w, 2w, 3w, and 4w), Figures 13A5-1 and 13B-8 (to reflect changes to Map I-2), Tables 12A1-1 and 13A1-1 (revised land uses in several stream locations), and Tables 13A5-1, 345A-1, and 26O-1 (to reflect above changes). The March 30, 2004, submittal also includes the Draft Study Plan for Burrowing Owls and Amphibians and revised Tables A and B for the Financial Responsibility section of the ERP. No material revisions are included in the submittals after March 30, 2004. Submittals after March 30, 2004, include financial responsibility forms, including a draft escrow agreement, and updated information on the temporary wetland crossing at the point that Stream 2e forms at the downstream end of the Heart-Shaped Wetland. The last item, dated April 20, 2004, is a revision of Figure 13B-8, but solely for the purpose of showing that the Heart-Shaped Wetland remains connected to Stream 2e, despite the temporary presence of a crossing. This is the last revision to the CDA prior to the commencement of the hearing. During the hearing, IMC submitted modifications of the mining and reclamation activities, and DEP agreed to all of these modifications. During the hearing, DEP proposed modifications of the mining and reclamation activities, and IMC agreed to all of these modifications. These modifications, such as identifying the annual hydroperiod of bay swamps as 8-11 months and the final changes to post-reclamation topography, are identified in this Recommended Order and incorporated into all references to the ERP or CRP approval. In general, the ERP addresses wetlands, surface waters, and species dependent upon either, and the CRP addresses uplands and species dependent exclusively upon uplands. Later sections of the Recommended Order will discuss the ERP, the CRP approval, and the WRP modification. All of the maps, figures, and tables incorporated into the ERP, CRP approval, or WRP modification are contained in the CDA. Overview of Mined Areas, No-Mine Areas, and Reclaimed Areas The ERP permits IMC to mine 3477 acres and requires IMC to reclaim 3477 acres. The ERP recognizes that IMC will not mine 721 acres, which is about 17 percent of the 4197-acre site. (Most acreage figures are rounded-off in this Recommended Order, so totals may not always appear accurate.) Although various exhibits and witnesses sometimes refer to the no-mine area as the preserved area, this label is true only insofar as IMC will "preserve" the area from mining. However, post-reclamation, the area is not preserved. After the property reverts to the Carlton-Smith family, it will return to its historical agricultural uses, subject to a Conservation Easement that is discussed below. Table 12A1-1 is the Mine Wide Land Use Analysis. Table 12A1-1 identifies, by acreage, each use or community presently at OFG, such acreage proposed to be mined, and such acreage proposed to be reclaimed. When not listed separately, this Recommended Order combines all non-forested wetlands, including mostly herbaceous wetlands and shrub marshes, into the category of herbaceous wetlands. Shrub marshes presently account for only 4.7 acres at OFG and will account for only 10.3 acres, post-reclamation. Ignoring 35 acres that presently are barren or in transportation or urban uses, the present uses or communities of OFG are agricultural (2146 acres), upland forests (904 acres), rangeland (510 acres), forested wetlands (380 acres), herbaceous wetlands (208 acres), and open water (15 acres). Nearly all of the existing agricultural uses are improved pasture (1942 acres); the only other use of significance is 165 acres of citrus. Well over half of the area to be mined is agricultural. Over half of the area to be mined is improved pasture (1776 acres, or about 51 percent of the mined area). Adding the citrus groves, woodland pasture, and insignificant other agricultural uses to the area to be mined, the total of agricultural uses to be mined is 1976 acres, or 57 percent of the mined area. The two most prevalent upland forest communities presently at OFG are sand live oak and pine flatwoods; the next largest community, hardwood-conifer mixed, accounts for about half of the size of sand live oak or pine flatwoods. These upland forests contribute about one-fifth of the area to be mined (731 acres, or 21 percent of the mined area). Cumulatively, then, agricultural land and upland forests constitute 78 percent of the mined area. For all practical purposes, all of the rangeland presently at OFG is palmetto prairie. This unimproved rangeland contributes a little less to the mining area that do upland forests; mining will consume 475 acres of rangeland, which is 14 percent of the mined area. Cumulatively, then, agricultural land, upland forests, and native rangeland will constitute 92 percent of the mined area. The addition of the remaining upland uses--25 acres of roads, 5 acres of barren spoil areas, and one acre of residential--results in a total of 3213 acres, or still 92 percent, of the 3477 acres to be mined. This leaves eight percent of the mined area, or 264 acres, as wetlands and other surface waters. As noted above, the wetlands are divided into forested and herbaceous wetlands. Forested wetlands will contribute 82 acres, or about two percent, of the mined area. Nearly all of the forested wetlands presently at OFG are divided almost equally among mixed wetland hardwoods, hydric oak forests, and bay swamps. Bay swamps total 104 acres. In terms of the forested wetlands present at OFG, mining will consume mostly mixed wetland hardwoods, of which 43 acres, or 36 percent of those present at OFG, will be mined. Mining will eliminate only nine acres, or nine percent, of bay swamps and six acres, or six percent, or hydric oak forests. Mining will eliminate a large percentage-- 67 percent--of hydric pine flatwoods present at OFG, but this is 12 acres of the 18 existing acres of this wetland forest community. Herbaceous wetlands will contribute 168 acres, or about five percent, of the mined area. Nearly all of the herbaceous wetland communities are wet prairies (108 acres) and freshwater marshes (81 acres). Mining will eliminate 95 acres, or 88 percent, of the wet prairie present at OFG, and 67 acres, or 83 percent, of the freshwater marshes present at OFG. IMC will mine 13.5 acres of open water, which consists primarily of cattle ponds and ditches. The only natural water habitat is natural streams, which total 2.2 acres. IMC will mine 0.9 acres of natural streams. Also incorporated into the ERP, Table 13A1-5, provides another measure of the impact of mining upon natural streams. According to Table 13A1-5, IMC will mine 2.8 acres of the 25.6 acres of natural streams. As noted in Table 13A1-5, reclamation of streams, which is discussed in detail below, is based on length, not acreage, and, under the circumstances, a linear measure is superior to an areal measure. Table 12A1-1 also provides the acreage of reclaimed community that IMC will construct. These habitats or uses are listed in the order of the size of the area to be reclaimed, starting with the largest. For agriculture, IMC will reclaim 1769 acres after mining 1976 acres. Adding the 170 acres of agriculture in the no-mine area, agricultural uses will total, post-reclamation, 1939 acres. For upland forest, IMC will reclaim 1055 acres after mining 731 acres. Adding the 173 acres of upland forest in the no-mine area, upland forest habitat will total, post- reclamation, 1227 acres. For rangeland, IMC will reclaim 323 acres after mining 475 acres. Adding the 35 acres of rangeland in the no- mine area, rangeland will total, post-reclamation, 358 acres. For herbaceous wetlands, IMC will reclaim 217 acres after mining 168 acres. Adding the 39 acres of herbaceous wetlands in the no-mine area, herbaceous wetlands will total, post-reclamation, 256 acres. For forested wetlands, IMC will reclaim 106 acres after mining 82 acres. Adding the 298 acres of forested wetlands in the no-mine area, forested wetlands will total, post-reclamation, 404 acres. ERP ERP Specific Condition 3 requires IMC to provide to DEP for its approval the form of financial responsibility that IMC chooses to use to secure performance of its mitigation costs. IMC may not work in any wetland or surface water until DEP has approved the method by which IMC has demonstrated financial responsibility. DEP shall release the security for each individual wetland that has been released by BMR, pursuant to Specific Condition 17. The escrow agreement is a two-party contract between IMC and J.P. Morgan Trust Company, as escrow agent. The escrow agreement acknowledges that IMC will transfer cash or securities to the escrow agent in the stated amount, representing IMC's obligations to perform ERP mitigation plus the ten percent add- on noted in the Conclusions of Law. If IMC fails to comply with the ERP or Section 3.3.7 of the SWFWMD Basis of Review, the escrow agent is authorized to make payments to DEP, upon receipt of DEP's written certification of IMC's default. The escrow agreement may be amended only by an instrument signed by IMC, DEP, and the escrow agent. ERP Specific Condition 3 requires IMC to calculate the amount of the security based on Table B, which is the Wetland Mitigation Financial Summary. Table B lists each forested and wetland community from Table 12A1-1, the acreage for each community, and the unit costs per acre of mitigation. The acreage figures are the acreage figures on Table 12A1-1. The unit costs per acre are as follows with the FLUCFCS codes in parentheses: herbaceous (641, 643)--$7304; forested bay wetland (611)--$11,692; other forested wetland (613, 617, 619, 630)--$11,347; shrub (646)--$8780; hydric palmetto prairie (648)--$9231; and (hydric) pine flatwoods (625)--$10,568. Table B also shows 10,141 feet of streams to be reclaimed at a cost per foot of $37, stream macroinvertebrate sampling at a total cost of $48,100, and water quality/quantity monitoring at a cost of $293,000. Adding the costs of wetland and stream reclamation, sampling, and monitoring, plus ten percent, Table B calculates the mitigation liability of IMC as $3,865,569. IMC has agreed to increase this amount for the reclamation of Stream 3e?. ERP Specific Condition 4 requires IMC to submit to BMR annual narrative reports, including the actual or projected start date, a description of the work completed since the last annual report, a description of the work anticipated for the next year, and the results of any pre-mining surveys of wildlife and endangered or threatened species conducted during the preceding year. The reports must describe any problems encountered and solutions implemented. ERP Specific Condition 5 requires IMC to submit to BMR annual hydrology reports. Relative to initial planting, IMC shall submit to BMR vegetative statistic reports in year 1, year 2, year 3, year 5, and every two years after year 5, IMC must submit to BMR vegetation statistic reports. ERP Specific Condition 6 addresses water quality in wetlands or other surface waters adjacent to, or downstream of, any site preparation, mining, or reclamation activities. Specific Condition 6.a requires, prior to any clearing or mining, IMC to sever the areas to be disturbed from adjacent wetlands. IMC severs or isolates the mining area when it constructs the ditch and berm adjacent to, but upland of, the adjacent wetlands not to be mined. Figure 14E-1 portrays the elements of the ditch and berm system as all outside of the no-mine area (or OFG property line, where applicable). In the illustration, from the mine cut toward the no-mine area (or OFG property line), IMC will construct the ditch, the 15-foot wide berm, the monitoring wells, and the silt fence. ERP Specific Condition 6.b requires the ditch and berm system to remain in place until IMC has completed mining and reclamation, monitoring indicates that no violation of "State Water Quality Standards" are expected, and DEP has determined that "the restored wetlands are adequately stabilized and sufficiently acclimated to ambient hydrological conditions." DEP's decision to allow the removal of the ditch and berm system shall be based on a site inspection and water quality monitoring data. Upon removal of the ditch and berm system, the area that had been within the ditch and berm system shall be restored to grade and revegetated according to the methods and criteria set forth in Specific Condition 14. ERP Specific Condition 6.c requires IMC to use best management practices for turbidity and erosion control to prevent siltation and turbid discharges in excess of State water quality standards, under Chapter 62-302, Florida Administrative Code. Specific Condition 6.d requires IMC daily to inspect and maintain its turbidity-control devices. If the berm impounds water above grade, IMC must daily visually inspect the integrity and stability of the embankment. ERP Specific Condition 7 requires that IMC implement a baseline monitoring program for surface water and groundwater and continue the program through the end of the mine life. The data from this program shall be included in the annual narrative reports described in Specific Condition 4. The locations of the sampling sites are depicted on Map D-4. ERP Specific Condition 7.a identifies three monitoring stations, which are in Horse Creek just upstream of the stream's entrance onto OFG (and possibly just upstream of the offsite confluence of Stream 2e with Horse Creek), in Horse Creek at State Road 64, and in West Fork a short distance upstream of its confluence with Horse Creek. Before and during mining, IMC must monthly monitor 18 parameters, including temperature, pH, dissolved oxygen, total suspended solids, conductivity, turbidity, color, total phosphorous, ammonia, nitrate/nitrite, and chlorophyll a. During mining, IMC must semi-annually monitor 11 additional parameters, including alkalinity, biological oxygen demand, chloride, and iron. ERP Specific Condition 7.b identifies one monitoring station, which is at the junction of Stream 6w and Horse Creek. Before and during mining, IMC must monthly monitor ten parameters, including temperature, pH, dissolved oxygen, total suspended solids, conductivity, and color. During mining operations, IMC must semi-annually monitor the same 11 additional parameters described in Specific Condition 7.a. ERP Specific Condition 7.c identifies two clusters of monitoring wells, one located near the offsite confluence of Stream 2e with Horse Creek and one located near the collecting station on West Fork near its junction with Horse Creek. During mining operations, IMC must semi-annually monitor 23 parameters, including pH, temperature, conductivity, alkalinity, total phosphorous, color, turbidity, chloride, iron, and nitrate/nitrite. ERP Specific Condition 8 requires IMC immediately to cease all work contributing to turbidity violations of "State Water Quality Standards established pursuant to Chapter 62-302, F.A.C." Specific Condition 8 requires IMC to stabilize all exposed soils contributing to the violation, modify work procedures that were responsible for the violation, repair existing turbidity-control devices, and install more such devices. Specific Condition 8 requires IMC to notify BMR within 24 hours of the detection of any turbidity violation. ERP Specific Condition 9 requires IMC to report all unauthorized releases or spills of wastewater or stormwater in excess of 1000 gallons per incident to BMR, as soon as practicable, but not later than 24 hours after detection. ERP Specific Condition 10 addresses water levels and flows in wetlands and other surface waters adjacent to, and downstream of, any site preparation, mining, and reclamation activities. Prior to any clearing or mining activities adjacent to no-mine wetlands and other surface waters, Specific Condition 10.a requires IMC to install monitoring wells and staff gauges and commence monitoring water levels, as required by ERP Monitoring Required, which is a part of the ERP that is discussed below. IMC shall monitor water levels in each of the no-mine streams at the point that it intercepts the 100-year floodplain of Horse Creek. ERP Specific Condition 10.a provides: During mining, recharge ditches adjacent to no-mine areas shall be charged with water or recharge wells shall be installed to maintain base flows and/or minimize stress to the vegetation in the preservation areas. Water levels in the recharge ditches shall be maintained at levels sufficient to support the normal seasonal water level fluctuations in the wetlands as determined from the baseline monitoring included in Table MR-1. Under ERP Specific Condition 10.a, prior to any clearing or mine activities, IMC must install monitoring wells and staff gauges and monitor water levels, as specified in the ERP Monitoring Required. IMC must daily monitor water levels in each of the no-mine streams at the point of its interception with the 100-year floodplain of Horse Creek. During mining, IMC shall charge recharge ditches with water or install recharge wells to maintain base flows and minimize stress to vegetation in no-mine areas. IMC must maintain water levels in the recharge ditches at levels sufficient to support the normal seasonal water level fluctuations in the wetlands, as determined from the baseline monitoring included in Table MR-1, which is described below. IMC must daily check the water levels in the recharge ditches, record this information in logs, and make these logs available to BMR during its quarterly inspections. IMC shall monthly inspect the water levels in adjacent no-mine wetlands and notify BMR in writing if these wetlands show signs of stress. If adjacent no-mine wetlands become stressed, upon DEP's approval, IMC will take additional actions, such as altering mining and reclamation procedures, modifying the recharge ditch, providing additional sources of water, and conducting additional monitoring. During the hearing, IMC hydrologist and engineer Dr. John Garlanger testified: "[IMC] will install a recharge well system along the preserved areas." (Tr., p. 2800) The parties treated recharge wells as a part of the ditch and berm system, both at the hearing and in their proposed recommended orders (DEP, paragraph 75; Charlotte County, paragraph 575; and IMC, paragraph 339.) However, Specific Condition 10.a imposes no such obligation upon IMC, nor does any other provision in the ERP or the CDA. The above-quoted provision of Specific Condition 10.a identifies recharge wells as an alternative. The other option in Specific Condition 10.a is to charge the ditches with water. This condition is confusing because it poses, as alternative requirements, one option of a specific effect--i.e., recharged ditches--and the other option of a means of achieving that effect--i.e., recharge wells. The objective is sufficient water in the ditch. The means of charging the ditch would appear to be limited to direct rainfall, pumping water from the mine cuts, diverting water from the mine recirculation system, or pumping water from the intermediate or Floridan aquifer through recharge wells; at least the first two of these charging options are already incorporated into the OFG ditch and berm system. Confirming that recharge wells are optional is Figure 14E-1, which labels the recharge well depicted at the bottom of the ditch as "Alternate--Recharge Well." Figure 14E-1 illustrates a pump forcing the water from the bottom of the deeper mine cut to the bottom of the recharge ditch. (Figure 14E-1 also illustrates that--in order, running from the mine cut toward the no-mine area (or OFG property line)--the ditch, the 15-foot wide berm, the monitoring wells, and the silt fence will all be located outside of the no-mine area (or within OFG).) ERP Specific Condition 10.b prohibits reductions in downstream flows from the project area that will cause water quality violations in Horse Creek or the degradation of natural systems. IMC shall monitor surface water levels continuously at the above-described points at State Road 64 and West Fork and monthly near the above-described junction of Stream 2e and Horse Creek. IMC shall monitor monthly at the above-described clusters of monitoring well locations and at piezometers located across Section 9 from the no-mine area into the uplands to the east, in the West Lobe and the adjacent uplands to the west, in the East Lobe and the adjacent uplands to the east, and in Horse Creek about one-quarter mile from the southern border of OFG. IMC shall daily monitor rainfalls at a rain gauge near the junction of Stream 2e and Horse Creek. IMC shall report the results of the monitoring in the reports required in Specific Condition 4. ERP Specific Condition 11 requires IMC to obtain authorization from FWC before relocating gopher tortoises or disturbing their burrows. ERP Specific Condition 11 also requires IMC to relocate gopher frogs and other commensals to FWC-approved sites before clearing. At the time of the hearing, FWC had not yet approved IMC's plan to relocate gopher tortoises, but this approval was expected shortly. ERP Specific Condition 12 requires IMC to complete mining, filling, and reclamation activities generally in accordance with the schedule stated in this condition. Specific Condition 12.a prohibits IMC from commencing severance or site preparation more than six months prior to mining, except as approved by DEP for directly transferring topsoil or muck to a contoured mitigation site. IMC must complete final grading, including muck placement, not later than 18 months after the completion of mining operations, which include the backfilling of sand tailings. IMC must conduct its hydrological assessment in the first year after contouring. ERP Specific Condition 12.a provides a timetable for work in wetlands and other surface waters. IMC may not commence severance or site preparation more than six months prior to mining. IMC shall complete final grading, including muck placement, not more than 18 months after the completion of mining operations, including backfilling with sand tailings. IMC shall complete Phase A planting, which is of species that tolerate a wide range of water levels, not more than six months after final grading or 12 months after muck placement. IMC shall conduct the hydrological assessment in the initial year after coutouring. IMC shall complete Phase B planting, which is of species that tolerate a narrower range of water levels, within 12 months after the hydrological assessment and Phase C planting, which is shade-adapted groundcover and shrubs, as well as additional trees and shrubs required to meet the density requirements of ERP Specific Condition 21 [sic; probably should be ERP Specific Condition 16], at least two years prior to release of forested wetlands. ERP Specific Condition 12.b provides that IMC shall clear, contour, revegetate, and reconnect wetlands and watersheds as shown in Tables 3AI-6A and 3AI-10A, Maps H-1, H-9, and I-6, and Figures 13B-8, 13A5-1, and CL-1. Table 3AI-6A lists each reclaimed wetland by number, the last year in which it will be disturbed, the last year in which it will be mined, the year in which grading will be completed, the year in which revegetation will be completed, and the number of years between mining or disturbance and reclamation and revegetation. The span of years between mining or disturbance and reclamation ranges from three (two wetlands) to eight (six wetlands). Table 3AI-10A is the Reclamation Schedule Summary. The table identifies four reclamation units in the Horse Creek sub-basin, one reclamation unit in the West Fork sub-basin, and one reclamation unit in the Brushy Creek sub-basin. For each reclamation unit, Table 3AI-10A shows the period of mining, period of mine operations, period for contouring, and period for revegetation. These years are relative: mining runs four years, mine operations run seven or eight years (starting one year after mining starts), contouring runs seven or eight years (starting within one year of the end of mining), and revegetation runs five or six years (starting one year after the start of contouring). Map H-1 is the Mine Plan. Map H-1 assumes four draglines will operate in OFG for five years of active mining. IMC's tentative plan is first to mine the west side of OFG, which is nearer the Ft. Green Mine at which the draglines are presumably deployed at present, and then to mine adjacent mining blocks. For instance, IMC would mine the northwest corner of Section 4 in Year 1, the southwest corner of Section 4 in Year 2, the northeast corner of Section 4 in Year 3, and the southeast corner of Section 4 in Year 4 before removing the dragline south of Section 4 to mine an unmined area in Year 5. Map H-1 depicts the ditch and berm system running continuously along the edge of the no-mine area from the north end of OFG, south along the no-mine borders that trace the east and west edges of the 100-year floodplain of Horse Creek, to their southern termini. On the east floodplain, the ditch and berm system turns east at the northwest corner of Section 21, near the Carlton cutout, runs to the easternmost extent of OFG, turns north to the northeast corner of Section 4, and runs to the northwest corner of Section 4, where the ditch and berm system ends. On the west floodplain, the ditch and berm system runs to the southernmost extent of OFG near its confluence with West Fork, turns west and north, as it traces the border of OFG along Sections 29, 20, and 19, where it ends at a point about one-quarter mile from the northern boundary of Section 19. For the areas closest to the no-mine area, Map H-1 also depicts the direction of the mine cuts and, inferentially, the spoil piles. These cuts and piles are generally perpendicular to the direction of Horse Creek. Figure 2AI-24 displays the locations of the six reclamation units identified in Table 3AI-10A. The West Fork and Brushy Creek reclamation units occupy the sub-basins bearing their names, so they are at the western and eastern edges, respectively, of OFG. The HC(1) reclamation unit is almost all of Section 4. According to Table 3AI-10A, IMC will mine this reclamation unit from 2006-09, contour it from 2009-15, and revegetate it from 2010-15. Combining the information from Map H-1 for the Stream 1e series, all of it but Stream 1ee, which is the most-downstream stream, will be mined in the first year of the sequence, and Stream 1ee will be mined in the second year. However, Stream 1ee will be disrupted longer because a 200 foot- wide dragline access corridor runs across it, just upstream of the Heart-Shaped Wetland, as shown on Map H-1 and Figure RAI 514-1. Map H-9 is the Tailing Fill Schedule. The tailings are the sand tailings; the clay tailings, which are called waste clays, are deposited in the CSAs. Sand tailings are backfilled into mine cuts starting in year 3, and the process is completed in year 7. Map H-9 reproduces the blocks shown on Map H-1, except for one change in Section 20, and adds two years to each block. An explanatory note on Map H-9 states that IMC will backfill and grade the upland areas immediately west of the West Lobe and east of the East Lobe with sand tailings within one year of mining. Map I-6 is the Post-Reclamation Streams. This Recommended Order addresses streams in detail below. As already noted, at the hearing, DEP identified Stream 3e? as another stream eligible for restoration under the eligibility criterion used in these cases, and IMC has agreed to restore this stream and add it to Map I-6. Figure 13B-8 is the Post-Reclamation Connection Status of the reclaimed wetlands. A map, Figure 13B-8 depicts connected wetlands, isolated wetlands, isolated wetlands that are ephemeral, and cattle ponds. Figure 13A5-1 is the Identification of Created Wetlands. Also a map, Figure 13A5-1 assigns numbers to each reclaimed wetland and identifies the habitat to be reclaimed. These two figures provide a good basis for comparing the reclaimed wetlands to the existing wetlands by type, location, size, and proximity to streams. These two figures confirm the removal of cattle ponds to points considerable distances from Horse Creek, streams, riparian wetlands, or even most isolated wetlands. Thirteen cattle ponds totaling 7.6 acres will be reclaimed on OFG. Generally, these cattle ponds are located as far away as possible from the 100-year floodplain of Horse Creek. Except for the cattle ponds and three connected reclaimed wetlands that drain to the West Fork or Brushy Creek, all of the connected reclaimed wetlands will be connected to Horse Creek, usually by streams, but in several cases directly to the 100-year floodplain of Horse Creek. Connected reclaimed wetlands include the headwater and intermittent wetlands of the Stream 1e series (E003/E006/E007/E008/E009/E013/E015/E016), the headwater wetlands of Stream 3e (E022/E023/E024), and the headwater wetlands of Stream 3e? (E018/E019/E020). The decision at the hearing to reclaim Stream 3e? is not reflected on Figure 13A5-1 or 13B-8, which depicts as isolated the large wetland to the northeast of the headwater wetland of Stream 3e. The Stream 1e series reclaimed wetlands complex totals 44.9 acres. The Stream 1e series existing wetlands complex covers a smaller area, perhaps 10 fewer acres. However, the reclaimed wetlands will be somewhat simpler. IMC will reclaim one freshwater marsh (E006) where five presently exist (G108, G115, G125, G126, and G129). IMC will replace two gum swamps (G123 and G121) and two wetland forested mixed (G102 and G132) with the predominant mixed wetland hardwoods (E003). IMC will replace one of the freshwater marshes with hydric oak forest. Just west of the riparian corridor, IMC will replace a wet prairie (G119) with a little hydric flatwoods (G119A) with another freshwater marsh (E014) and will mine a small wet prairie (G028) to the east of the corridor and not replace it with any wetland. On the plus side, IMC will add two very small bayheads (E008--0.7 acres and E013--0.7 acres) to the west side of the corridor and will relocate and expand a large hydric flatwoods (G107) that is beside a small unreclaimed community--a hydric woodland pasture (G105). The reclamation of the headwater of Stream 3e better re-creates the existing wetlands, in size and type of community. The only change is the conversion of a shrub marsh (G134) in the center of the wetland to a freshwater marsh (E023), essentially enlarging the freshwater marsh (G135) presently in the center of this wetland. The size of the existing and reclaimed wetlands associated with the riparian corridor of Stream 3e and its headwater wetland appear to be the same. The reclamation of the headwater of Stream 3e? provides a more complicated complex of wetland communities than presently exists at that location. The ditch (G019) will be replaced with a natural stream, whose riparian corridor is not depicted due to the fact that IMC agreed to reclaim Stream 3e? at the hearing; however, the reclaimed wetland corridor undoubtedly will be more functional than the present ditch. Presently, the headwater wetland is a large freshwater marsh (G016) fringed by mixed wetland hardwoods (G014) and a wet prairie (G105). A cattle pond (G017) is in the wet prairie, and another cattle pond is at the point where Stream 3e? forms. The north side of this wetland is heavily ditched. The reclaimed headwater wetland, which will be about the same size as the present wetland, will consist of an interior shrub marsh (E019) and freshwater marsh (E020) and a wet prairie fringe (E018). A replacement cattle pond (E026) is moved farther away from the headwater wetland. Reclamation around the Heart-Shaped Wetland results in a more complicated array of wetlands than presently exists. Three ephemeral wet prairies (E021, E026, and E031) will be reclaimed north and west of the Heart-Shaped Wetland and Stream 2e where no wetland exists presently. An isolated freshwater marsh (E034) will be reclaimed south of the Heart-Shaped Wetland where no wetland exists today. Two ephemeral wet prairies (E026 and E037) totaling 4.5 acres will be reclaimed south and east of Stream 2e, close to the no-mine area surrounding Streams 6e and 7e, again where no wetland exists presently. However, IMC will not reclaim a hydric flatwoods (G157) connected to the south border of the headwater wetland of Stream 8e. Reclamation will relocate the headwater wet prairie of Stream 9w closer to Horse Creek. Mining two wet prairies (G047 and G048) and reclaiming them with a single wet prairie of at least the same size (W003--20.7 acres), IMC will also reclaim the downstream portion of Stream 9w with a mixed wetland hardwoods and add a gum swamp (W005--2.4 acres) at the end of Stream 9w, as it enters the no-mine corridor of Horse Creek. IMC will also reclaim an ephemeral wet prairie (W002) just north of the reclaimed segment of Stream 9w. Across Horse Creek from its junction with Stream 9w, IMC will mine the eastern half of a roughly five-acre bayhead (G166), reclaiming the mined part of the bayhead with a mixed wetland hardwoods (E048--6.0 acres). However, where no wetlands presently exist, IMC will reclaim an ephemeral wet prairie (E044) and a larger wetland consisting of a freshwater marsh (E047--9.0 acres) fringed by an ephemeral wet prairie (E046--7.1 acres). In RAI-173 in the CDA, IMC explains that no-mine lines initially ran through some wetlands due to the limited level of detail available in the small scale maps used at the time. IMC representatives have discussed each such bifurcation with DEP biologist Christine Keenan, and IMC made adjustments that satisfied DEP, obviously not eliminating all of the bifurcated wetlands. Alluding to the impracticability of eliminating all bifurcated wetlands, IMC notes in its response to the request for additional information: "A small feature protruding into a mining area is one of the more difficult features to effectively mine around. It requires significant extra distance of ditch and berm systems, which both increases costs and results in greater losses of phosphate ore recovery." Subject to two exceptions, the southernmost extent of reclaimed ephemeral wetlands will be close to the Lobes, especially the West and Central Lobes. Eight such wetlands (W021, W015, W017/W018, W019/W020, W012, W013, W016 and W011) will be west of Horse Creek, and three such wetlands will be east of Horse Creek (E057, E061, and E053). (Although the headwater wetland of Stream 7w, W012 is depicted as ephemeral in Figure 13B-8.) Most of these wetlands will be wet prairies. Three of these reclaimed ephemeral wetlands appear to be in the location of existing wetlands (G093/G094, G091/G092, and G090), and the existing wetlands are freshwater marshes fringed with wet prairies, except that the smallest, G090, is a wet prairie. The last reclaimed wetland on the east side of Horse Creek is just north of the Carlton cutout. In reclaiming Stream 5e, IMC will reclaim a small bayhead (E063--1.3 acres) in the middle of the stream's OFG segment. This replaces a wet prairie/hydric oak forest (G204/G205) in the same location and of the same size. On the other side of Horse Creek and to the south of Stream 5e, IMC will reclaim the headwater wetlands of Streams 5w, 4w, 3w, and 2w. The headwater wetland of Stream 5w is a long freshwater marsh (G210) with a small shrub marsh (G207) that drains an elaborate array of agricultural ditches to the west. These ditches shifted some of the drainage that historically entered Stream 4w into Stream 5w. Reclaiming the stream with a wider wetland forested mixed corridor, as it will do for Streams 4w, 3w, and 2w, IMC will expand the headwater wetland by reclaiming a long freshwater marsh (W024--7.9 acres) fringed on its upgradient side by a small wet prairie (W023--2.2 acres). IMC will also remove a cattle pond (G209) presently abutting the center of the freshwater marsh. IMC will reclaim an ephemeral wet prairie (W026) between Streams 5w and 4w, relatively close to the Horse Creek floodplain. Except for a very small ephemeral wet prairie just west of the headwater wetland of Stream 4w and an ephemeral, largely mixed wetland hardwoods reclaimed in the West Fork sub- basin (W041/W042/W043), W026 is the southernmost reclaimed ephemeral wetland on OFG. The pattern of the reclamation of Streams 4w, 3w, and 2w is otherwise identical: each reclaimed stream, in a reclaimed wetland forested mixed corridor, will receive water from reclaimed freshwater marshes of 3.5 to 5.1 acres in size. Presently, Stream 4w has no headwater marsh, instead receiving water from the elaborate ditching scheme described in connection with Stream 5w. Streams 3w and 2w presently receive water from small headwater wetlands, although Stream 2w also receives water from an agricultural ditch. The last major reclamation on the west side of Horse Creek relates to Stream 1w. Alone of all the streams, Stream 1w is an agricultural ditch throughout its length, except for a short segment just upstream from the no-mine area. However, alone of all the streams at OFG, Stream 1w drains a primarily seepage-supported wetland. This well-defined headwater wetland complex comprises, from upstream to downstream, a cattle pond (G505), freshwater marsh (G506), mixed wetland hardwoods (G507), bay swamp (G513), wetland forested mixed (G512), wet prairie (G514), hydric oak forest (G511), and ditch (G512A). Reclaimed, this headwater will be the largest reclaimed bay swamp (W0399-1.2 acres). In addition to the two small bay swamps in the wetland corridor of Stream 1e series, the small bay swamp in Stream 5e, and the Stream 1w headwater bay swamp, the only other bay swamp to be reclaimed on OFG will be a part of a wetland (W037/W036) that will be in the center of Section 19 and drain into the West Fork. The bay swamp component of this wetland will be 4.4 acres and will replace a similarly sized wetland (H008/H009/H009A) with a smaller bay swamp core. Map CL-1 is the Reclamation Schedule. This map identifies the year in which specific areas within OFG will be reclaimed. With two exceptions, Map CL-1 tracks Map H-9, which is the Tailing Fill Schedule, by identifying the same blocks and adding two years to each of them. One exception may be due to the February 19, 2004, and February 26, 2004, revisions of Map H-9. The latter revision changed the year of backfilling part of northwestern Section 20 from year 7 to year 5. Map CL-1 tracks the older version of Map H-9 and provides for reclamation of this area within Section 20 for year 9, not year 7. This means that part of the northwestern Section 20 would remain backfilled, but not revegetated, for four years. This may be an oversight in Map CL-1 because it was last revised January 22, 2004. The other exception concerns the uplands immediately east of the East Lobe. Map H-9 provides for sand tailings for the northern half of this area in year 6 and for the southern half of this area in year 5, but Map CL-1 provides for both areas to be reclaimed in year 7, so the southern half would remain backfilled, but not revegetated, for two years. This may be intentional, as ERP Specific Condition 12.d requires that IMC backfill and contour the two areas upslope of the bayheads in the West and East Lobes within one year after the completion of mining, but nothing in the ERP requires expedited revegetation of these upland areas. ERP Specific Condition 12.b requires IMC to include mining and reclamation schedule updates in the annual reclamation report that it files, pursuant to Chapter 62C-16, Florida Administrative Code. Specific Condition 12.b warns that "significant changes" to these schedules may require a permit modification. ERP Specific Condition 12.c states, in its entirety: "Mine cuts shall be oriented in the direction of ground water flow, generally perpendicular to Horse Creek as shown on Map H-1." The introduction to the January submittal, witnesses, and parties agree that IMC is required to orient the spoil piles in the direction of groundwater only to the extent practicable, so the unconditional language of ERP Special Condition 12.c is inadvertent. ERP Specific Condition 12.d provides that sand tailings placement and final contouring shall be completed within one year after the completion of mining, as shown on Map H-9, in the two areas upslope from the unmined bayheads (G178 and G197), which are in the East and West Lobes. ERP Specific Condition 13 addresses the construction, removal, and revegetation of the pipeline corridor shown on Figure RAI 514-1. This figure depicts a narrow "Mine Access Corridor (Pipelines, Road, Powerlines)" passing at the point that Stream 2e forms at the downgradient end of the Heart-Shaped Wetland. Specific Condition 13 contains seven subsections governing the pipeline corridor to minimize its impact on the wetlands and other surface waters that it crosses. Figure RAI 514-1 also depicts a 200-foot wide "Dragline Walkpath Corridor" that crosses Stream 1ee and Stream 3e within 100 feet of the Heart-Shaped Wetland. No conditions attach to the construction, operation, removal, and reclamation of this area because, unlike the pipeline corridor as it crosses Stream 2e, all of this portion of the dragline corridor will be mined. ERP Specific Condition 14 states that IMC shall restore as mitigation 322 acres of wetlands, as shown in Maps I-1, I-2, I-3, and I-6; Figure 13A5-1; and the post-reclamation cross-sections. Map I-1 is the Post Reclamation Topo. IMC updated this map with several limited changes at the end of the hearing, and DEP accepted the new Map I-1. Comparing Map I-1 with Map C-1, which is the Existing Topography, the post-mining topography substantially replicates the pre-mining topography, although Table 26M-1 reveals a lowering of some of the highest pre-mining elevations, including the highest elevation by eight feet. Maps I-2 and I-3 are, respectively, Post Reclamation Vegetation and Post Reclamation Soils. As noted above, Specific Condition 14 references these maps, but only in connection with the restoration of 322 acres of wetlands. Maps I-2 and I-3 cover all of OFG, so they cover wetlands and other surface waters, which are properly the subject of an ERP, and uplands, which are properly the subject of a CRP approval. Naturally, the ERP does not incorporate the all of Maps I-2 and I-3 because they include all of the uplands. Unfortunately, as discussed in the next section, the CRP approval likewise fails to obligate IMC to reclaim the uplands in accordance with Map I-2 and the upland soils in accordance with Map I-3. This omission is inadvertent, so the Recommended Order will assume that IMC will reclaim the uplands as depicted in Map I-2 and the upland soils as depicted in Map I-3. Although the upland portions of Maps I-2 and I-3 should be discussed in the next section, they will be discussed in this section because the CRP approval fails to incorporate them and discussing both maps in one place allows for a more coherent presentation. Map I-2 is the Post Reclamation Vegetation. Map I-2 depicts the post-reclamation upland and wetland vegetation on OFG. This map reveals wide edges of roughly one-quarter to one- half mile of reclaimed improved pasture on the east and west edges of OFG. The core of OFG is Horse Creek and its 100-year floodplain, which are always within, but do not always define, the no-mine area. Between the no-mine area and the reclaimed improved pasture are the reclaimed wetlands described above and larger area of reclaimed uplands described below. Map I-2 and Map F-1, which is Pre Mining Vegetation, allow a comparison, by community, location, and area, of reclaimed uplands with existing uplands. In broad overview, IMC will reclaim everything in Section 4 outside the Heart-Shaped Wetland, which is the northernmost extent of the no-mine area, and Stream 2e. From the point that Horse Creek enters OFG, IMC will reclaim a broad area between the no-mine area and reclaimed improved pasture, south to the Carlton cutout. From this point, reclamation will be limited to the west side of Horse Creek, and the area between the no-mine area and reclaimed improved pasture will narrow progressively for the remaining 1 1/2 miles that Horse Creek runs in OFG. The width of the core, or no-mine area, is generally about 750 feet, but widens considerably at different points. Where Horse Creek enters OFG, the no-mine area is approximately 1750 feet wide, but narrows south of Stream 8e to about 750 feet. From the Central Lobe to the East Lobe, the no-mine area expands to nearly 4000 feet across. Except for another expansion at the West Lobe, the width of the no-mine area south of the Lobes remains at about 750 feet until Horse Creek exits OFG. The riparian wetlands of Horse Creek, which are within the no-mine area, are mixed wetland hardwoods for the first mile that Horse Creek flows in OFG and hydric oak forest for the remainder of Horse Creek's passage through OFG. The width of the non-pasture uplands adjacent to the no-mine area also varies. In describing the width of these upland areas between the no-mine area and the reclaimed improved pasture, this Recommended Order will include the reclaimed wetlands described above. These wetland areas are small, except for the headwater wet prairie of Stream 9w, the headwater freshwater marshes of Streams 5w, 4w, 3w, and 2w, and a few isolated wetlands. On both sides of Stream 2e, IMC will reclaim a band of hardwood conifer mixed of about one-half mile in width. At present, this area is occupied by a smaller area of hardwood conifer mixed and nearly a one-half mile wide band of pine flatwoods or, to the south, pine flatwoods and sand live oak. East of Streams 6e, 7e, and 8e, IMC will reclaim a band 1500-3000 feet wide of hardwood conifer mixed, shrub and brushland, and sand live oak, between the no-mine area and the reclaimed improved pasture. This replaces a broader area of pine flatwoods, sand live oak, palmetto prairie, and xeric oak. From Stream 8e south, IMC will reclaim uplands on both sides of Horse Creek. At this point, the reclaimed area between the no-mine area and the reclaimed improved pastures measures about 1750 feet wide on the west of Horse Creek and about 2000 feet wide on the east of Horse Creek. Including the no-mine area in the center, these reclaimed areas average about one-mile wide south to the Lobes. From Stream 8e south to the East Lobe, IMC will reclaim largely hardwood conifer mixed. This replaces a large citrus grove, a larger area of improved pasture, and three smaller areas of palmetto prairie. On the west side of Horse Creek, the vegetation is more varied, both at present and as reclaimed. North of Stream 9w, IMC will reclaim a large palmetto prairie, a sizeable area of sand live oak, and a small area of temperate hardwood. South of Stream 9w, IMC will reclaim a large area of hardwood conifer mixed, areas of pine flatwoods, sand live oak, and palmetto prairie, and a small area of temperate hardwood. The uplands surrounding Stream 9w presently consist of improved pasture along the downstream half of the conveyance and palmetto prairie and sand live oak along and near its upstream reach. South of Stream 9w are a large area of improved pasture, pine flatwoods, and sand live oak and two smaller areas of palmetto prairie. The combination of no-mine area and reclaimed area, exclusive of reclaimed improved pasture, attains its greatest width--about 10,000 feet--from the western edge of the West Lobe to the eastern edge of the East Lobe, although this includes a 1000-foot strip of improved pasture between the bayhead in the East Lobe and sand live oak east of the bayhead. This area narrows to less than 6000 feet, just north of the Carlton cutout. South of this point, at which the reclaimed upland habitat will be found only on the west side of Horse Creek, the total width of the no-mine area and reclaimed area east of the reclaimed improved pasture tapers down from a little over 3000 feet to less than 1500 feet at the south end of OFG. Map I-2 also discloses the communities or habitats that will exist, post-reclamation, on OFG. These communities or habitats include those that will be in the no-mine area and those that will be reclaimed. At present, the West Lobe is mostly bayhead, wet prairie, and wetland forested mixed with smaller areas of hydric woodland pasture and shrub marsh. The West Lobe also includes upland communities of palmetto prairie, temperate hardwoods, and pine flatwoods. A large wet prairie extends from the northwest corner of the West Lobe. IMC will reclaim this wet prairie as improved pasture with a small strip of hardwood-conifer mixed. To the west of the West Lobe is a small strip of improved pasture and a large area of hardwood-conifer mixed. IMC will reclaim the improved pasture with hardwood-conifer mixed and sand live oak and most of the hardwood-conifer mixed with sand live oak. The areas surrounding the no-mine area associated with Stream 6w are currently improved pasture; IMC will reclaim these areas as hardwood-conifer mixed. The Central Lobe is mostly bayhead with small areas of wetland forested mixed and wet prairie. Palmetto prairie is also within the Central Lobe, nearer to Horse Creek. IMC will reclaim the areas around the Central Lobe and Stream 7w with hardwood-conifer mixed and some palmetto prairie. At present, the Central Lobe and Stream 7w are surrounded by palmetto prairie and some pine flatwoods with an area of sand live oak to the northwest of the Central Lobe. Unlike the no-mine areas forming the West and Central Lobes, which incorporate insubstantial areas of uplands, the no- mine area forming the East Lobe, like the no-mine area around Streams 6e, 7e, and 8e, incorporates a substantial area of uplands. Upgradient of the large bayhead forming the western half of the East Lobe is the 1000-foot strip of improved pasture, and upgradient of the pasture is a large sand live oak area. IMC will mine the eastern half of this sand live oak area and reclaim it as xeric oak. IMC will mine a small wet prairie presently at the southern tip of the bayhead in the East Lobe and reclaim the area as hardwood-conifer mixed. From the East Lobe south to the Carlton cutout, the reclaimed uplands will consist of a long area of temperate hardwoods abutting the no-mine area and a wider area of hardwood-conifer mixed abutting the temperate hardwoods. This area is presently improved pasture. On the west side of Horse Creek, south of the Carlton cutout, the area outside the no-mine area is presently improved pasture, except for a large palmetto prairie around and south of the headwater wetland of Stream 1w. Between the no-mine area and reclaimed improved pasture, IMC will reclaim palmetto prairie and a small area of hardwood-conifer mixed between the headwater wetlands of Streams 5w and 3w. Map I-3 is the Post Reclamation Soils. The legend classifies the soils by "[moderately well-drained]--greater than 30"; "[poorly drained]--greater than 30"; "[poorly drained]-- less than 30"; "[poorly drained]--stream"; "[very poorly drained]--muck"; and "[very poorly drained--mineral depression]." The references to "30" are the thicknesses, in inches, of sand tailings over overburden. Maps E-1 and E-2 are, respectively, Detailed Existing Soils and General Existing Soils. Comparisons between these two maps, on the one hand, and Map I-3, on the other hand, reveal specifics of the soil-reclamation process. The most distinctive feature of soils present at OFG is the thin band of Felda Fine Sand, Frequently Flooded, that runs down the center of OFG. As always, this reinforces the most distinctive feature of OFG--Horse Creek. However, the Felda Fine Sand extends beyond the Horse Creek floodplains to Stream 2e, the Stream 1e series, and the headwater wetland of Stream 5w. All of these soils are in the no-mine area except at the Stream 1e series and headwater wetland of Stream 5w. A closely related soil underlies the floodplain of the lower end of Stream 6w, which is also in the no-mine area. These are the only locations on OFG with these soils. The Felda Fine Sand is a "poorly drained soil having layers of loamy and/or spodic materials underlying sandy surfaces at least 20 inches thick on streams terraces and floodplains." Exclusive of the loamy or spodic materials, Map I-3 shows that IMC will reclaim the drainage characteristics of this type of soil at the Stream 1e series, but not at the headwater wetland of Stream 5w. IMC will also reclaim this type of soil at Streams 9w, 5w, 4w, 3w, 2w, and 1w. Another distinctive soil, pre-mining, is "moderately well to excessively drained soils having layers of loamy and/or spodic materials underlying sandy surfaces greater than 30 inches thick on gentle upland slopes and rises." Except for a couple of areas at the eastern end of the East Lobe, these soils presently are all outside of the no-mine area. IMC will reclaim these soils, generally in the areas previously described as sand live oak or xeric oak, as well as in a long band along the southern border of the slough associated with Stream 9w and a large area on the west sides of Sections 29 and 20. These areas correspond reasonably well in area and location to the existing soils with the same drainage characteristics. The two most poorly drained soils, pre-mining, are "very poorly drained to poorly drained mineral soils in depressions" and "very poorly drained soils with organic surfaces on low gradient seepage slopes." The latter are exclusively mucky soils, and the former range from mucky fine sand to fine sand. Most of the mucky soils are in the no-mine area, such as in each of the Lobes and along Streams 6e and 7e. IMC will not reclaim with similar soils the three areas with these mucky soils that are outside the no-mine area. The mucky fine soils are more widely distributed outside the no-mine area. The only significant areas of fine mucky sand presently at OFG underlie the Heart-Shaped Wetland, the headwater wetland of Stream 8e, and parts of the West Lobe. IMC will reclaim these mucky fine soils generally in accordance with their present areas and locations. The most significant reductions in area are from the slough of Stream 9w and the northeast corner of Section 4. Except for another category of poorly drained soil and four small areas of a somewhat poorly drained soil--all within the no-mine area--the remaining soil is "poorly drained soils having layers of loamy and/or spodic materials underlying sandy surfaces predominantly greater than 30 inches thick primarily on gently sloping uplands." The reclaimed counterpart of this poorly drained soil occupies the largest part of OFG, post-reclamation. This represents a substantial expansion of coverage of this type of soil, mostly at the expense of "poorly drained soils having layers of loamy and/or spodic materials underlying sand surfaces less than 30 inches thick primarily on gently sloping uplands." Map I-6 is the Post Reclamation Streams. These are addressed below. Figure 13A5-1 is the Identification of Created Wetlands. These wetlands have already been discussed. ERP Specific Condition 14 states that IMC shall reclaim wetlands in accordance with the schedule contained in Table 3AI-6A, which has been discussed. Specific Condition 14 lists various requirements applicable to the wetlands that IMC will create. ERP Specific Condition 14.a requires IMC to remove "suitable topsoil" prior to mining wetlands. IMC must time the clearing of topsoil donor sites and reclaiming of other sites so that it optimizes the opportunities for the direct transfer of topsoil, without any intervening storage time. If IMC must remove wetland topsoil more than six months before it will be spread at a reclamation site, IMC must store the topsoil in such a way as to minimize oxidation and colonization by nuisance species. Specific Condition 14.a encourages IMC to relocate any endangered or threatened plant species to appropriate mitigation sites. ERP Specific Condition 14.b requires IMC to grade reclaimed forested wetland areas after backfilling them with sand tailings and/or overburden and cap them with "several inches of wetland topsoil." IMC shall use direct transfer of topsoil and live materials, such as stumps, shrubs, and small trees, where feasible. However, Specific Condition 14.b states in boldface: "All reclaimed bay swamps shall receive several inches of muck directly transferred from forested wetlands approved for mining." Specific Condition 14.b provides that wetland topsoil should be reasonably free of nuisance and exotic plant species before application to wetland mitigation areas. ERP Specific Condition 14.c requires IMC to grade reclaimed herbaceous and shrub marsh wetland areas after backfilling them with sand tailings and/or overburden and cap them with "several inches of wetland topsoil when available." Specific Condition 14.c provides that wetland topsoil should be reasonably free of nuisance and exotic plant species before application to wetland mitigation areas. ERP Specific Condition 14.d requires IMC to design marshes and wet prairies "to maintain the diversity of community types that existed prior to mining in order to support a wide range of wildlife species including birds, reptiles, and amphibians." Specific Condition 14.d requires IMC to reclaim marshes and wet prairies with variations in hydroperiod and slope "to provide the greatest diversity of available habitat," with marsh hydroperiods ranging from ephemeral through permanently flooded. Specifying a range of slope values, Specific Condition 14.d adds that most marshes shall have slopes gradual enough to support wide transition zones with a diversity of vegetation. ERP Specific Condition 14.d provides that IMC shall construct ephemeral marshes and wet prairies as identified in Figure 13B-8, which, discussed above, addresses the status of individual wetlands as connected, isolated, or isolated and ephemeral. Although not incorporated into the ERP, Table 13A1-4 indicates that IMC will mine 27 of the 29 ephemeral wetlands or 22 of the 27 acres of ephemeral wetlands, but will reclaim 44 ephemeral wetlands totaling 101 acres, as indicated on Table 13A5-1 2AI discussed above. ERP Specific Condition 14.e provides that at least half of all herbaceous and shrub marshes shall be rim mulched with several inches of wet prairie, pine flatwoods, or palmetto prairie topsoil, and IMC shall use direct transfer, where feasible. ERP Specific Condition 14.f requires IMC to use "several inches" of wet prairie, hydric pine flatwoods, or hydric palmetto prairie topsoil for all wet prairie and hydric palmetto prairie areas, and IMC shall use direct transfer, where feasible. However, instead of topsoiling, IMC may use "[o]ther innovative methods" that are likely to produce the same diversity of wet prairie forbs and grasses. ERP Specific Condition 14.g requires IMC to construct, in forested wetlands, hummocks several inches above the wet-season high water line. The hummocks shall be 8-12 feet long and 3-6 feet wide. To increase habitat heterogeneity, IMC shall place brushpiles, logs, and tree stumps in the reclaimed area, which it shall roughly grade in some areas. ERP Specific Condition 14.h requires IMC to construct streams in accordance with the Stream Restoration Plan. Specific Condition 14.h also requires IMC to employ an experienced stream restoration scientist, subject to BMR approval, to provide project oversight and conduct regular inspections during construction and planting. First appearing in the January submittal, the Stream Restoration Plan is a design document that specifies, in detail, the physical characteristics of each reclaimed stream. For each reclaimed stream or stream segment, the Stream Restoration Plan provides detailed information of physical structure; channel planform or shape; hydrologic characteristics in terms of such factors as storage, conveyance, and attenuation; geomorphic characteristics such as the substrate and floodplain soil types and the effects of flows upon these materials; vegetation along the stream corridor, including the addition of snags and debris dams to re-create natural microhabitats; construction supervision; and monitoring. The Stream Restoration Plan focuses upon the design of the basin, reach, and microhabitat of each reclaimed stream. For microhabitat, the Stream Restoration Plan promises that: the ecology of most of the reaches is expected to be improved through reclamation. For all reaches except 1e and 3e (which are wholly situated in generally native land cover), the forested riparian zone will be substantially increased since improved pasture adjacent to the stream channels will [be] replaced with forested canopy. Acknowledging the importance of small headwater streams to the overall integrity of a large watershed, the Stream Restoration Plan recognizes the hydrological and biological functions of the tributaries and their riparian wetlands--namely, flood conveyance, attenuation, and storage and aquatic and wetland habitat. Among other things, the Stream Restoration Plan repeatedly stresses the importance of achieving "rapid closure of the riparian canopies." In addition to providing habitat, a riparian canopy reduces solar heating of the stream, thus lowering the water temperature and minimizing weedy vegetation on the stream banks. Among the effects of lowering the water temperature is lowering the amount of water lost to evaporation. The installation of trees along and sometimes within the reclaimed channels will facilitate the rapid development of root systems to stabilize the substrate and provide submerged root structure, which is an important microhabitat for macroinvertebrates and fish. Mature trees in the floodplain also provide additional attenuation. In addition to serving as a design document to govern the reclamation of mined streams on OFG, the Stream Restoration Plan is also a descriptive document, detailing the relevant characteristics of the streams presently at OFG. The Stream Restoration Plan uses several classifications that are useful in analyzing streams and their functions. These classifications include the Rosgen classification of stream shape (the Rosgen classification of bottom sediment is irrelevant because all existing and reclaimed streams at OFG have sandy bottoms), the Strahler convention of stream orders, the duration of flow, and the channel morphology. The Rosgen classification of stream shape divides the streams at OFG into type E and type C. Type E streams are well- incised and hydraulically efficient; their width-to-depth ratios are less than 12:1. Shallower and wider than type E streams, as these values relate to each other, type C streams at OFG are often associated with small wetland riparian zones and depressions, which are absent from type E streams at OFG. The Strahler convention classifies streams based on their relative location in the upstream order of conveyances with the most-upstream streams classified as first-order streams. Except for Stream 2e and the Stream 1e series downstream of Streams 1eb and 1ef, all of the tributary streams on OFG are first-order streams, meaning essentially that they are the most upstream channelized conveyance receiving runoff or groundwater flow. Streams 2e, 1ec, 1ed, and 1ee are second- order streams, meaning that they receive flow from at least two first-order streams. In terms of flow, perennial streams receive groundwater flow throughout the year in most years, ephemeral streams flow sporadically in response to rain and typically lack groundwater inputs, and intermittent streams flow during the wet season in response to groundwater and rain inputs and during the dry season sporadically in response to rain inputs only. Most, if not all, of the tributary streams on OFG are intermittent. However, almost all of the streams cease to flow due to low rainfall and overflow their banks due to very high rainfall. Even Horse Creek dried up at State Road 64 during the low-rain conditions in 2000. In terms of morphology, all streams at OFG are either in uninterrupted channels or interrupted channels. Interrupted channels mean that the stream passes through flow-through marshes and swamps. Describing the existing streams in a slightly larger setting, the Stream Restoration Plan divides them into three groups, based on channel morphology and the vegetation and land uses adjacent to the channel. First, Streams 3e and 1e series are "surrounded by native habitat used for low-intensity cattle grazing. These are type C streams with a more diffuse riparian canopy and associated wetlands along the stream channel." Second, the portions of Streams 5e, 1w, 2w, 3w, 4w, 5w, 7w, and 9w within the floodplain forest of Horse Creek are type E streams with oaks and palmettos along, and often crowding, the channel. Third, the portions of the same eight streams that are outside of the floodplain forest of Horse Creek are type E streams, devoid of riparian vegetation and degraded by agricultural land uses, such as improved pasture and cattle grazing. The Stream Restoration Plan describes the Stream 1e series as follows: Reach 1e provides drainage for a series of interconnected flow-through wetlands punctuated by five relatively short stream segments. The segments represent a total of some 2,039 linear feet of channel. They have shallow, sandy banks with little vegetation in the stream channel. A wide riparian canopy of slash pine, laurel oak, dahoon holly and wax myrtle is present along most of this reach. The palmetto edge of the floodplain varies in width, but is generally more than 100 feet from either bank, suggesting frequent inundation. The channel substrate is sandy except where near a swamp, where it becomes increasingly more organic. Each flow-through wetland occurs in shallow depressions which overflow into C-type channels that are typically several hundred feet long. Key components of this conveyance type include the lip elevation at which wetland flow enters the channel and the elevation at which the streams dissipate their discharge to the downstream flow- through wetland. Most of the stream segments in this conveyance system appear to be in good geomorphic condition. Most of these channels typically have wetland and/or upland hardwood trees in the riparian zone with little understory. The Stream Restoration Plan reports that the channel of Stream 3e is in good geomorphic condition. The upper part of the channel flows through a scattered open canopy of trees with herbaceous cover in the riparian zone. The lower part of the channel mostly flows through treeless banks lined with palmettos. The channel has vegetation in it where it is exposed to sunlight. In other respects, Stream 3e is like Stream 1e series, except that the channel is uninterrupted and shorter. The length of Stream 3e is 611-630 feet. Stream 1eb is 486 feet, Stream 1ef is 223 feet, Stream 1ec is 315 feet, Stream 1ed is 283 feet, and Stream 1ee is 732 feet. The 2039-foot length of the Stream 1e series is exclusive of the system's headwater and flow-through wetlands. The Stream 1e series has the most linear feet of any tributary stream on OFG. In addition to the Stream 1e series and Stream 3e, the only other stream on the east side of Horse Creek to be mined is Stream 5e, which is an agriculturally disturbed stream with a narrow riparian canopy. The Stream Restoration Plan states that the lower portion of Stream 5e, which is within OFG, is in better condition than the upper portion, which is frequented by cattle and leads to a cattle pond and agriculturally altered wetland. However, in contrast to the Stream 1e series and Streams 6e, 7e, and 8e, Stream 5e is isolated in a vast monocommunity of improved pasture. The streams on the west side of Horse Creek have all been impacted by agricultural practices, mostly cattle ranching, ditching streams, sloughs, and other wetlands, and excavating cattle ponds in wetlands. The only streams entirely in the no- mine area on the west side of Horse Creek are Streams 8w and 6w, which are part of the Central and West Lobes, respectively. Relative to their surrounding communities, the streams on the west side of Horse Creek fall into three groups. Streams 6w and 8w are integrated into diverse communities of uplands and wetlands. Like Stream 5e, Streams 5w, 4w, 3w, and 2w are lonely departures from the monocommunity of improved pasture and, thus, attractors of thirsty or hot cattle. All of these streams have been impacted, to varying degrees, by ditching, which, with cattle disturbances, has led to unstable banks and erosion. Functionally, Streams 9w, 7w, and 1w are between these two groups. As a stream, Stream 9w is surrounded by improved pasture; however, it drains a large wet prairie surrounded by large areas of palmetto prairie to the south and west and sand live oak to the north and east. Prior to agricultural disturbance, Stream 9w was much higher functioning, at least with respect to flood conveyance, attenuation, and storage. At one time, this stream led upgradient to a long slough. After the slough was ditched to hasten drainage, the channel of Stream 9w suffered from excessive hydraulic forces, resulting in bank instability and a curious channel formation that fits the type E stream, even though the valley slope is consistent with other type C streams at OFG. Stream 9w is the second-shortest stream on OFG at 472 feet. Draining the smallest area of all tributaries on OFG (30 acres), Stream 7w lies between a large palmetto prairie to the north and improved pasture to the south. Stream 7w is the shortest stream on OFG at 456 feet. Stream 7w's upper section is characterized by unstable banks vegetated by pasture grasses. Stream 1w runs from Horse Creek through improved pasture, but enters a large palmetto prairie before draining a wetland that includes a relatively small bayhead. The upper half and extreme lower portions are in good condition with appropriate vegetation, but the channel is eroded in areas where it runs through pasture. IMC will reclaim the headwater wetland of Stream 1w with a large bayhead. ERP Specific Condition 14.i requires IMC to survey the final contours of each mitigation wetland to the precision of a one-foot contour. Within 60 days of final grading, IMC shall submit to BMR, for its approval, a topographic map and representative cross sections for each wetland and extending at least 200 feet into the adjacent uplands. IMC must also submit surveyed profiles and cross sections for all reclaimed streams. All topographic maps must meet the minimum technical standards of Chapter 472, Florida Statutes. ERP Specific Condition 14.j states that IMC shall assess the hydrology of the modeled wetlands through the installation of monitoring wells and staff gauges at mutually agreed-upon sites in these reclaimed wetlands. For at least two years after the final contouring of each wetland, IMC shall monitor the hydrology for the parameters listed in Table MR-2, which is described below. IMC shall submit the analysis to BMR within 30 days of its completion. If BMR does not approve the hydrology, IMC shall have 60 days to submit a remedial plan. ERP Specific Condition 14.k requires that freshwater marsh and ephemeral marsh vegetation shall develop from direct placement of donor topsoil or planting of herbaceous marsh species in the densities and numbers specified in the Freshwater Marsh and Wet Prairie/Ephemeral Marsh planting tables, so as to meet the requirements of ERP Specific Condition 16. Both tables require plantings on three-foot centers, or 4840 plants per acre, and specify suitable water levels for each species. The Freshwater Marsh planting table lists 22 approved species, and the Wet Prairie/Ephemeral Marsh planting table lists 35 approved species. ERP Specific Condition 14.l requires IMC to plant the uplands surrounding wet prairies with collected native grass seed, such as creeping bluestem, sand cordgrass, blue maidencane, bluestem, lovegrass, and eastern gamma grass, to prevent invasion by non-native or range grasses. ERP Specific Condition 14.m provides that IMC shall develop shrub marsh vegetation by directly placing donor topsoil at the location of the reclaimed shrub marsh and planting herbaceous and shrub marsh species in the densities and numbers specified in the Shrub Marsh planting table, so as to meet the requirements of ERP Specific Condition 16. The Shrub Marsh planting table requires IMC to plant herbaceous species on three-foot centers, or 4840 plants per acre, and shrub species at an average density of 900 plants per acre. The planting table lists 18 approved species and requires IMC to plant at least five different shrub species. The planting table also specifies suitable water levels. ERP Specific Condition 14.n provides that IMC shall plant forested wetlands in the densities, species richness, and dominance specified in the Bay swamp/Gumswamp/Hydric Oak Forest/Wet Pine Flatwoods/Mixed Wetland Hardwood/Mixed Forest Swamp, "as appropriate for each community type" to meet the requirements of ERP Specific Condition 16. IMC shall plant appropriate species based on the design elevations, hydrology monitoring, and mitigation goals. ERP Specific Condition 14.o provides that IMC shall plant shade-tolerant herbaceous species after establishing suitable shade, by year 7, in hardwood swamps, mixed forest swamps, and bay and gum swamps. Specific Condition 14.o states: "At least 5 of the species listed in the Tables in n above and others like goldenclub . . . and swamp lily . . . shall be planted." The items listed in Specific Condition 14.n, however, are communities, not species. ERP Specific Condition 15 requires IMC to implement a monitoring and maintenance program to promote the survivorship and growth of desirable species in all mitigation areas. ERP Specific Condition 15.a requires IMC to conduct "quarterly or semi-annual" inspections of wetlands for nuisance and exotic species. IMC shall control these species by herbicide, fire, hydrological, or mechanical means "to limit cover of nuisance species to less than ten (10) percent and to remove exotic species when present in each created wetland." IMC must annually use manual or chemical treatment of nuisance and exotic species when their cover in any area of at least one acre is greater than ten percent or any exotic species are present. IMC must use manual or chemical treatment if cogongrass covers more than five percent within 300 feet of any reclaimed wetland. ERP Specific Condition 15.b allows IMC to control water levels with outflow control structures and pumps, as needed to enhance the survivorship and growth of sensitive taxa. However, IMC must remove all water management structures at least two years prior to requesting release. ERP Specific Condition 15.c requires IMC to make supplemental tree and shrub plantings, pursuant to Specific Condition 14, when tree/shrub densities fall below those required in ERP Specific Condition 16. Specific Condition 15.d requires IMC to make supplemental herbaceous plantings, pursuant to ERP Specific Condition 14, when cover by a "diversity of non- nuisance, non-exotic wetland species as listed in Chapter 62-340.450, F.A.C.," falls below that required in ERP Specific Condition 16. ERP Specific Condition 16 provides the conditions for DEP to release IMC of further obligation for reclaimed wetlands. DEP shall release the 105 acres of reclaimed forested wetlands and 217 acres of herbaceous wetlands when IMC has constructed them in accordance with the ERP requirements; IMC has not intervened, for two consecutive years (absent BMR approval), by irrigating, dewatering, or replanting desirable vegetation; and the remaining requirements of ERP Specific Condition 16 have been met. IMC must indicate in its annual narrative, which is required by Specific Condition 5, the start date for the non- intervention period. ERP Specific Condition 16.A requires that the water quality meet Class III standards, as described in Florida Administrative Code Chapter 62-302. ERP Specific Condition 16.B addresses water quantity. ERP Specific Condition 16.B.1 requires each created wetland to have hydroperiods and inundation depths sufficient to support wetland vegetation and within the range of conditions occurring in the reference wetlands of the same community for the same period, based on the monitoring data developed in accordance with ERP Specific Condition 14.j. Tributary wetlands must have seasonal flow patterns similar to specified reference wetlands for the same period. ERP Specific Condition 16.B.2 states that IMC modeled 24 representative reclaimed wetlands that IMC has modeled during the application process to predict subsurface conditions after excavation and backfilling. Figure 13-3 depicts these modeled wetlands, which are within 13 wetland complexes, and the proposed transects. All of the modeling transects are aligned east-west, which is the direction of groundflow. As discussed in detail below, the primary hydrological model used by Dr. Garlanger requires an input for the length of the upland in terms of the distance from the basin divide to the riparian wetland. Therefore, the transects probably must run in the direction of groundwater flow. Absent an ability to model the hydroperiod and inundation depth of a wetland across a sand tailings valley and cast overburden plateau--i.e., in a north-south direction-- multiple east-west transects in wetlands with long north-south dimensions would better reveal whether the wetland design were adequately accounting for the alternating pattern of sand tailings valleys and cast overburden plateaus. For all the areas for which Map H-1 provides probable orientations of spoil piles--basically, for present purposes, everywhere but Section 4--the spoil piles are oriented in the same alignment as the transects, so the transects will not cross the sand tailing valleys/cast overburden peaks. In other words, each of the transects will run along the portion of each wetland for which the relative depths of sand tailings and cast overburden remain constant, avoiding the potentially more problematic situation of alternating rows of sand tailing valley and cast overburden peak. As noted below, the north-south dimension of W039 assures that one cast overburden spoil pile and part of another will underlie W039. The north-south dimensions of W003 and E046/E047 also are long enough to guarantee significant alterations in geology. ERP Specific Condition 16.B.2 requires that, prior to the construction of the modeled 24 wetlands, IMC shall reassess and, if necessary, modify their design. The modifications shall be based on the targeted hydroperiods and inundation depths set forth in Table 1, which is described below, and updated analysis from an "integrated surface and ground water model that has been calibrated to actual field conditions at the location of the wetland to be constructed." Lastly, ERP Specific Condition 16.B.2 requires IMC to use a similarly calibrated model to design the other reclaimed wetland, so that they achieve the targeted hydroperiods and inundation depths set forth in Table 1. For the 24 modeled wetlands, Table 1 identifies eight types of wetland community, prescribes hydroperiods and inundation depths for each wetland habitat, and projects a hydroperiod for each of the 24 modeled wetlands. As amended at the hearing for bay swamp hydroperiods, the hydroperiods and inundation depths for the wetland communities are: bay swamps-- 8-11 months with inundation depths of 0-6 inches; gum swamps-- 3-12 months with inundation depths of 0-12 inches; mixed wetland hardwoods and wetland forested mix--3-9 months with inundation depths of 0-6 inches; hydric pine flatwoods--1.5-4.5 months with inundation depths of 0-6 inches; freshwater marshes--7-12 months with inundation depths of 6-30 inches; wet prairies--2-8 months with inundation depths of 0-6 inches; and shrub marshes--7-12 months with inundation depths of 6-24 inches. The 24 reclaimed wetlands to be modeled include three bay swamps: W039, which is the headwater wetland of Stream 1w; E008, which is a small part of the wetland into which Streams 1eb and 1ef drain; and E063, which is a small bay swamp in the middle of Stream 5e. The only other bay swamps to be reclaimed are E007, which is a small part of the wetland into which Stream 1ec drains, and W036, which is in the center of Section 19 and drains offsite into West Fork. The only other modeled wetlands that are part of the riparian wetlands of Stream 1e series are E007 and E009, which are near E008 and are the only hydric pine flatwoods to be modeled. The only other hydric pine flatwoods to be reclaimed is E015, which is also part of the riparian wetlands of Stream 1e series. Other modeled wetlands of particular importance are W003, which will be a large wet prairie wetland serving as the headwater wetland of Stream 9w; W031, which will be the freshwater marsh serving as the headwater wetland of Stream 3w; E018, E046, and E057, which are wet prairie fringes; E018, E042, E046, and E057, which are ephemeral wetlands (E042 is the only modeled ephemeral wet prairie that is not a fringe wetland); and all of the connected wetlands of Streams 3e and 3e?: E024, which is a wetland forested mix that is the riparian wetland along Stream 3e; E023, which is a freshwater marsh immediately upstream of E024; E022, which is a mixed wetland hardwoods joining the upstream side of E023; E018, which is a wet prairie fringing the headwater wetland of Stream 3e?; E019, which is a shrub marsh (the only modeled shrub marsh) fringed by E018; and E020, which is a freshwater marsh joining E019 and also fringed by E018. ERP Specific Condition 16.B.3 states the IMC shall monitor the 24 modeled wetlands, as prescribed by ERP Monitoring Required Section D and Table MR-2, which are discussed below. ERP Specific Condition 16.B.4 requires that the ephemeral wetlands shall remain inundated no more than eight months per year during a normal water year, which is between the 20th and 80th percentiles of historical record in terms of total rainfall and major storm occurrence. ERP Specific Conditions 16.C.1 and 2 apply to all mitigation areas within the scope of the ERP. Specific Condition 16.C.1 requires that non-nuisance, non-exotic wetland species listed in Florida Administrative Code Rule 62-340.450 cover at least 80 percent of the groundcover or attain the range of values documented in specific reference wetlands of the target community. Desirable groundcover plant species must be reproducing naturally. ERP Specific Condition 16.C.2 provides that nuisance vegetation species, such as cattail, primrose willow, and climbing hemp vine, shall cover less than 10 percent of the total wetland area. Invasive exotic species, such as melaleuca, Chinese tallow, and Brazilian pepper, shall not be considered as an acceptable component of the vegetative community. For herbaceous marshes, ERP Specific Condition 16.C requires that native species typical of the reference marshes dominate the cover and that they be distributed in zonation patterns similar to reference marshes. Species richness and dominance regimes shall be within the range of values documented within the reference marshes. For wet prairies, ERP Specific Condition 16.C requires that native species typical of the reference wet prairies dominate the cover. Species richness and dominance regimes shall be within the range of values documented within the reference wet prairies. Range grasses, such as bahiagrass and Bermuda grass, shall cover, in total, less than 10 percent of the wet prairie. For shrub marshes, ERP Specific Condition 16.C requires that native species typical of the reference shrub marshes dominate the cover. Carolina willow and wax myrtle shall cover, in total, less than 30 percent of the marsh. For all forested wetlands, ERP Specific Condition provides that the forested canopy shall have an average of at least 400 live trees per acre that are at least 12 feet tall, except for cabbage palms, which shall have a leaf, including the stalk, that is at least three feet long. In the alternative, the forested canopy shall meet or exceed the range of canopy and sub-canopy tree densities in specified reference wetlands. No area greater than an acre shall have less than 200 trees per acre. Hydric pine flatwoods shall average 50 trees per acre. For all forested wetlands, ERP Specific Condition provides that the shrub layer shall average at least 100 shrubs per acre or shall meet or exceed the range of shrub densities in specified reference wetlands. Early successional species, such as Carolina willow, saltbush, and wax myrtle, do not count in meeting this density requirement, but the monitoring reports shall include such species. Hydric pine flatwoods shall have an average density of 350 shrubs per acre, and the primary species shall be typical of hydric pine flatwoods, such as saw palmetto, gallberry, and fetterbush. For all forested wetlands, ERP Specific Condition states that the canopy and shrub strata shall each have the species richness values and dominance regimes within the range of values in specified reference wetlands/floodplains of the target community. Canopy and shrub measurements are limited to those indigenous species that will contribute to the appropriate strata of the mature forested wetlands/floodplains. Up to half of the trees and shrubs in the upper transitional zone may consist of appropriate upland and facultative species, as found in specified reference wetlands. Desirable canopy and shrub species shall be reproducing naturally. For all forested wetlands, ERP Specific Condition provides that herbaceous vegetation shall have the species richness values and dominance regimes within the range of values in specified reference wetlands/floodplains of the target community. In making this evaluation, DEP shall consider the relative age of the mitigation site, as compared to specified reference wetlands. ERP Specific Condition 16.D.1 requires that all stream banks be stable, subject to normal erosion and deposition zones, as evidenced by the conformance of the stream with the applicable Rosgen type C or E, as described in the appropriate reference streams. ERP Specific Condition 16.D.2 requires that the physical characteristics of the reclaimed stream conform to its design. ERP Specific Condition 16.D.3 requires that tree roots, log jams, snags, and other instream structure shall be present at desirable intervals along the reclaimed stream. ERP Specific Condition 16.D.4 provides that species diversity and richness of the macroinvertebrate community shall be within the range of values documented in the reference streams or reported values of similar streams systems in central Florida. Also, all functional feeding guilds of macroinvertebrates found in the reference streams shall be present in the reclaimed streams. In the alternative, IMC may show that the reclaimed stream has met the minimum thresholds for the "good" classification in DEP's Stream Condition Index for macroinvertebrates and habitat quality. ERP Specific Condition 16.E provides that, throughout OFG, at least 105 acres of reclaimed forested wetlands and 217 acres of reclaimed herbaceous wetlands shall be determined to be wetlands or other surface waters. IMC shall achieve the minimum acreage for each wetland, as indicated on Map I-2 and associated figures and tables. However, IMC may make minor changes in the size, shape, or location of individual reclaimed wetlands, subject to BMR's approval. ERP Specific Condition 17 provides that DEP shall release IMC from further obligation regarding mitigation when ERP Specific Condition 16 has been met. IMC initiates the release procedure by notifying DEP that IMC believes the mitigation is ready for release, but this notice may not be earlier than two years after the completion of mitigation. DEP must respond within 120 days. ERP Specific Condition 17.d provides: "[DEP] may release the mitigation wetlands based on a visual evaluation, notwithstanding that all the requirements of Specific Condition 16 have not been met." ERP Specific Condition 18 applies to the surface water management system. The system must conform to the plans, specifications, and performance criteria approved by the ERP. ERP Specific Condition 19 requires IMC clearly to identify all no-mine areas in the field within two years of the issuance of the ERP. ERP Specific Condition 20 states that BMR will review the ERP at the end of the first five-year term after its issuance and at the end of each succeeding five-year term, if any. The purpose of the review is to determine compliance with general and specific conditions, including monitoring requirements. BMR staff shall quarterly inspect the mine for compliance with these requirements. ERP Specific Condition 21 requires IMC to provide a phased Conservation Easement, in favor of DEP, on 525 acres of OFG, as depicted on Figure F-6. Figure F-6 shows two easement areas. Phase A, which is 372 acres, corresponds to the 100-year floodplain of Horse Creek. Phase A is in the no-mine area. Phase B, which is 153 acres, is a wider band running along both banks of the northernmost 1 1/2 miles of Horse Creek and mostly on only the west bank for the southernmost 2 miles of Horse Creek. Phase B consists of part of the reclaimed area. The corridor covered by both phases of the Conservation Easement is generally not wider than 1000 feet and thus does not capture all of the non-improved pasture upland communities reclaimed on either side of Horse Creek and described above. IMC is required to grant the Conservation Easement on the Phase A lands within six months of the issuance of the ERP. IMC is required to grant the Conservation Easement on the Phase B lands within six months of the release by DEP of IMC from further obligations regarding reclamation and mitigation. ERP Specific Condition 21 incorporates the Conservation Easement and Easement Management Plan. The Conservation Easement implicitly acknowledges the fact that IMC is contractually obligated to convey OFG back to the Carlton- Smith family, after IMC has been released from further obligations regarding reclamation and mitigation. Thus, post- mining, OFG will return to its historic agricultural uses-- mostly, cattle ranching. The restrictions and encumbrances included in the Conservation Easement are designed to provide some protection to the wetlands, streams, and uplands within the Phase A and Phase B areas. Granted to the Board of Trustees of the Internal Improvement Trust Fund of the State of Florida, for which DEP serves as an agent, the Conservation Easement allows IMC and its successors, including the Carlton-Smith family, to use the encumbered property for cattle ranching, but only to the extent consistent with "sustainable native range management practices." These sustainable native range management practices require, among other things, the natural renewal of the grazing capacity of the land by allowing native grasses and other native forage species to regenerate. The Easement Management Plan contemplates prescribed burns of portions of the corridor. The Conservation Easement also allows IMC and its successors, upon obtaining the necessary permits, to construct a commodious 200-foot wide accessway across the encumbered property for a road, pipelines, draglines, and/or utilities. ERP Specific Condition 22 requires IMC to enhance 80 acres of existing pastureland within several areas of the Horse Creek floodplain, as indicated on Figure F-5, which is Habitat Enhancements. Most of the depicted enhancement areas are on OFG, but two of them are a short distance from OFG. ERP Specific Condition 22 requires IMC to plant 100 longleaf pines and/or oaks per acre within several sites, covering 80 acres of existing pastureland, adjacent to the 100-year floodplain of Horse Creek. Most of the sites are on the west bank of Horse Creek, mostly south of the Lobes, but a couple of sites are on the east bank in the vicinity of the East Lobe. ERP Specific Condition 23 requires that IMC plant these areas within one year of the issuance of the ERP and that the overall survival rate be at least 80 percent, as of the time of the release of the last mitigation parcel. ERP Specific Condition 23 requires IMC to enhance existing xeric and scrub habitats within areas designated as ACI (Area of Conservation Interest)-2, ACI-4, and ACI-6, as depicted on Figure F-5. Specific Condition 23 states that IMC shall enhance the wildlife habitat of these areas by performing controlled burns, cutting overgrown trees, planting desirable species, and controlling nuisance and exotic species. Specific Condition 23 obligates IMC to complete these enhancements within three years of the issuance of the ERP. ACI-2 is about 1 1/2 miles west-southwest of the southern end of OFG, between State Road 64 and the West Fork. ACI-2 consists of about 60 acres of overgrown xeric habitat, featuring 40 acres of sand scrub, predominantly sand live oak. Gopher tortoises occupy ACI-2 at a density of about 1.6 reptiles per acre. Florida mice occupy ACI-2 at a density of 0.4 rodents per acre, meaning that only 15-25 Florida mice may occupy ACI-2. By fence-posting overgrown sand pine and sand live oak and conducting a prescribed burn, IMC will reduce the heavy canopy existing on ACI-2 and enhance the suitability of ACI-2 for gopher tortoises and Florida mice. IMC will also apply herbicides to nuisance exotic species, such as bahiagrass, after which IMC will direct seed the flatwoods on the site with suitable vegetative species. Following this work, IMC may relocate Florida mice from OFG to ACI-2, upon approval from the FWC. ACI-6 is about one mile east of the southern end of OFG. ACI-6 consists of about 421 acres of a mixture of open land and overgrown oak scrub. Gopher tortoises occupy ACI-6 at densities ranging from 0.7 to 1.8 animals per acre. After fence-posting overgrown oaks and sand pine, conducting prescribed burns, installing fencing to exclude cattle and feral hogs, applying herbicide to kill exotic species, and direct seeding appropriate vegetation, IMC may relocate Florida mice from OFG to ACI-6, upon approval from FWC. ACI-4 consists of about 82 acres at the eastern end of the East Lobe and is within the no-mine area. The western end of ACI-4 slopes to the west through a bahia pasture before it enters a large bay swamp at the western end of the East Lobe. This area has been impacted by partial clearing and the depositing of animal carcasses--the latter practice yielding the name assigned to this area, the "boneyard" scrub. ACI-4 is dominated by mature scrub oaks. Gopher tortoises occupy ACI-4 at the rate of 0.85 terrestrial turtles per acre, and gopher frogs frequent the mouths of tortoise burrows at the site, although no signs of Florida mice exist. After conducting enhancement activities similar to those to be conducted on the other ACIs, IMC intends to create and maintain more suitable habitat for Florida mice. Specific Condition 23 states that IMC shall enhance 25 acres of pasture on ACI-4 by planting 100 longleaf pines and/or oak trees, and IMC shall manage these areas to achieve an overall survival rate of 80 percent through release of the final reclamation parcel. ERP Specific Condition 24 notes that IMC has committed to initiate the management and evaluation of amphibians, including the Florida gopher frog, and shall adhere to the management plans outlined in the IMC Minewide Gopher Tortoise and Burrow Conceptual Management Plan that FWC has examined, but not yet approved. IMC shall expend at least $30,000 to compare amphibian use of reclaimed and unmined wetlands. IMC shall include progress reports as to this study with its annual narrative reports required under Specific Condition 4. ERP Specific Condition 25 incorporates Tables 2AI-1 and 2AI-2 to provide assurance that IMC has sufficient sand tailings for the timely reclamation of wetlands contemplated in the ERP. Table 2AI-1 is the IMC Overall Sand Balance. Table 2AI-2 is the [OFG] Sand Balance. Table 2AI-1 shows the sand tailings production of IMC's Four Corners and Ft. Green mines from 2004-2014 and assumes an initial mining year of 2006 for OFG. For each of these 11 years, Four Corners produces 27,000,000 tons of sand tailings. For the first seven of these years, Ft. Green produces 17,000,000 tons of sand tailings. During these 11 years, IMC needs anywhere from 13,300,000 to 54,900,000 tons of sand tailings to meet all of its reclamation obligations. The closest that IMC will come to exhausting its sand tailings stockpile will be in year 6 of the OFG mining operation (2011, if OFG mining starts in 2006). For this and the following year, the sand tailings stockpile will total 300,000 tons. By this time, IMC's requirements for sand tailings begin to taper off, so that, by the final year on the schedule (2014), the sand tailings stockpile increases to 20,600,000 tons. Table 2AI-2 shows that IMC can meet its reclamation obligations for the Ft. Green Mine and OFG without using any stockpiled sand tailings. The next section of the ERP is Monitoring Required. The designations for this section start with a letter. As its name suggests, ERP Monitoring Required describes the monitoring program. The presence of monitoring does not imply the presence of standards or criteria applicable to what is monitored or the presence of a remedy or sanction for noncompliance with any standard or criterion. The existence of this section of the ERP does not mean that other sections of the ERP may impose monitoring requirements, applicable standards and criteria, and remedies or sanctions for noncompliance. ERP Monitoring Required A.1 requires IMC to submit annual narrative reports to BMR detailing the progress of the restoration program identified in ERP Specific Condition 4. As required in ERP Specific Condition 5, IMC shall submit to BMR hydrology reports annually and vegetation reports annually for the first three years and every other year thereafter, until release. At least 60 days prior to sampling, ERP Monitoring Required A.2 requires IMC to submit, for agency approval, vegetation, hydrology, and macroinvertebrate monitoring plans detailing sampling techniques and locations. ERP Monitoring Required A.3 requires IMC to include in its annual hydrology reports the daily rainfall amounts for the Ft. Green and OFG gauges shown on Map D-4. ERP Monitoring Required A.4 states that, if BMR determines that restoration efforts are not trending toward achievement of the release conditions set forth in ERP Specific Condition 16, IMC shall have 30 days from notification to submit proposed corrective actions. IMC shall implement corrective actions within 90 days of their approval. ERP Monitoring Required B states that data compiled in the CDA will be the primary source of reference wetland information. IMC shall then collect additional stage and hydroperiod data from the modeled wetlands. Within one year of the issuance of the ERP, IMC shall submit to BMR, for approval, a proposed sampling plan, including locations, frequencies, and vegetation, hydrology, and macroinvertebrate sampling methods. ERP Monitoring Required B provides that IMC shall select several wetlands of each community and submit them to BMR for approval. It appears that this process has already been completed, and DEP should updated ERP Monitoring Required B by incorporating into the ERP Figure RF-1, which, although not presently incorporated into the ERP, identifies 26 reference wetlands on OFG and nine reference wetlands on the original Ona Mine to the east of OFG. These reference wetlands include the most important components of the Lobes, the Heart-Shaped Wetland, Stream 2e's riparian wetlands, several wetlands in the Stream 1e series, the headwater wetland of Stream 3e, isolated wetlands south and east of the headwater wetland of Stream 3e, parts of the headwater wetland of Stream 1w, and the riparian and headwater wetlands of Stream 8e. As noted below, the riparian and headwater wetlands of Stream 8e, which are selected as reference wetlands, are moderate functioning, but the riparian and headwater wetlands of Stream 7e, which are not selected as reference wetlands, are high and very high functioning. ERP Monitoring Required C is Compliance Monitoring. Monitoring Required C.1 provides that IMC shall submit water quality data with the annual narrative reports submitted pursuant to ERP Specific Condition 7. All monitoring reports must include specified information, such as the dates of sampling and analysis and a map showing sampling locations. ERP Monitoring Required C.2 states that IMC shall submit hydrology data with its annual narrative reports. ERP Monitoring Required C.3 states that IMC shall monitor water levels in wetlands in no-mine areas in accordance with Table MR-1, which is described below. ERP Monitoring Required C.4 notes that IMC shall measure and report surface water flows in accordance with ERP Specific Condition 10. IMC must include in its reports to BMR all U.S. Geologic Service data collected at State Road 64 and State Road 72, which is south of State Road 64, and rainfall data collected by the U.S. Geologic Service, Southwest Florida Water Management District, and IMC. The annual hydrographs for Horse Creek at State Road 64 and State Road 72 "should" be similar. IMC must obtain and report hydrological data from 30 days after the issuance of the ERP until three years after the hydrological reconnection of the last reclaimed area upstream of a water level monitoring location. Within 60 days of the receipt of such data, BMR shall notify IMC of any changes to mining or reclamation that are necessary, and IMC shall have 60 days to respond to this notice. ERP Monitoring Required C.5 grants IMC a 50-meter temporary mixing zone adjacent to construction and in waters of the state; provided, however, this mixing zone is in effect only during the construction of the pipeline crossing just downstream of the Heart-Shaped Wetland. IMC must halt construction if monitoring reveals that turbidity at the site is more than 29 NTUs above upstream locations. ERP Monitoring Required C.6 states: "Compliance Monitoring Summary--See Table MR-1." Table MR-1 is discussed below, in connection with Table MR-2. ERP Monitoring Required D is Release Criteria Monitoring. Applying to vegetation, Monitoring Required D.1 provides that IMC shall conduct all monitoring of herbaceous vegetation during or immediately after the summer growing season. Monitoring Required D.1 requires the reports to include a description of collection methods and location maps. IMC must report data separately for individual wetlands. IMC must report separate density and cover information for trees, shrubs, and groundcover, as well as information about any supplemental planting. Applying to water quantity, ERP Monitoring Required D.2 provides that IMC shall submit water quantity data with its annual narrative reports, as required in ERP Specific Condition 4. IMC shall collect onsite daily rainfall data at OFG. ERP Monitoring Required D.3 requires: "Soils, macroinvertebrates and stream channel integrity/morphology shall be monitored as described in Table MR-2." ERP Monitoring Required D.4 states: "Release Monitoring Criteria Summary--See Table MR-2." Tables MR-1 and MR-2 refer to the monitoring required for compliance and release, respectively. The identification of these tables as "summaries" and the vague references to them in ERP Monitoring Required C.6 and D.4 suggest that the tables do not contain any performance standards and may imply that, except for the asterisked notes in Table MR-1, they summarize all of the performance standards and criteria contained in the ERP. If summaries, the tables should not introduce new elements, but they do just that with respect to the methods, sampling schemes, and frequency of monitoring. For water quantity monitoring, for instance, Table MR-2's promise of weekly readings of monitoring wells and piezometers for part of the year conflicts with the monthly reading required in ERP Specific Condition 10.b. If summaries of performance standards and criteria, the tables should capture all of the compliance and release criteria, but they do not. For water quality, for example, Table MR-2, which is limited to five parameters, potentially conflicts with ERP Specific Condition 16.A's broad assurance of compliance with Class III water quality standards, which encompass a broad range of parameters, including iron. For water quantity, Table MR-2 also omits the enforceable streamflow criteria of ERP Specific Condition 10.b. For soil, Table MR-2 includes one parameter--litter accumulation--for which no corresponding criterion exists and includes substrate-- for which important criteria exist as to the depths of sand tailings, topsoil, green manure, and muck--but omits any release criteria. Addressing two of the most important parts of the ERP--monitoring and performance criteria--these tables must be interpreted as subordinate to the remainder of the ERP, so that if they conflict with another ERP provision, the other ERP provision controls, but if they add a requirement not elsewhere found in the ERP, the requirement applies to the proposed activities. Table MR-1 is the Compliance Monitoring Criteria Summary. Table MR-1 identifies two monitoring parameters: water quality and water quantity. Asterisked notes state that the Table MR-1 requirements for water quality are in addition to those set forth in Specific Condition 7, which are discussed above, and the Table MR-1 requirements for water quantity are in addition to those set forth in Specific Condition 10.b, which are discussed above. For water quality, Table MR-1 addresses only turbidity. The compliance criterion is the Class III standard. The "proposed methods" are for IMC to monitor water, at mid- depth, 50 meters upstream and downstream from the point of severance and reconnection of each wetland. The frequency of monitoring is daily during severance or reconnection or during pipeline corridor construction or removal. The duration of monitoring is at least one wet season prior to mining, during mining, and through contouring. For water quantity, Table MR-1 addresses water levels, flow, hydrographs, soil moisture, and plant stress. The compliance criteria are soils sufficiently moist to support wetland vegetation and prevent oxidation and water levels in recharge ditches sufficient to simulate normal seasonal fluctuations of water in adjacent wetlands and other surface waters. The "proposed methods" are for IMC to install staff gauges, monitoring wells, piezometers, and flow meters in recharge ditches and wetlands in the no-mine area and at the point that the 100-year floodplain of Horse Creek intercepts the unmined portions of Streams 2e, 6e, 7e, 8e, 9e, 6w, and 8w. The frequency of monitoring is to check rainfall and recharge ditches daily, staff gauges in streams "continuously," and monitoring wells and piezometers weekly. The duration of monitoring is at least one wet season prior to mining, during mining, and through contouring. Table MR-2 is the Release Monitoring Criteria Summary. Table MR-2 identifies five monitoring parameters: water quality, water quantity, stream channel integrity and morphology, soils, and vegetation. For water quality, Table MR-2 addresses dissolved oxygen, turbidity, temperature, pH, conductivity, and, for all streams, all of the parameters in ERP Specific Condition 7.a. The compliance criteria are Class III standards. The locations are at or near the connection of wetlands in the no-mine area and at or near vegetative transects in streams and representative wetlands. The frequency is monthly from May to October prior to the reconnection to wetlands in the no-mine area and monthly from May through October of the year prior to the release request. The duration of monitoring is at least two years after the completion of contouring. For water quantity, Table MR-2 addresses water levels, flow, hydroperiod, rainfall, and hydrographs. The release criteria are values within the range of values documented in specified reference wetlands for each community type and, for hydroperiods and water levels, within the range of values predicted by modeling. The "proposed methods" are the same instruments identified for water quantity in Table MR-1. The locations for sampling are at or near the connection to wetlands in the no-mine area and at representative locations, including the deepest depths, of several representative wetlands of each community type. The frequency of monitoring is to check rainfall daily, staff gauges in streams "continuously," monitoring wells and piezometers weekly from May through October and monthly from November through April, and flow at sufficiently frequent intervals to generate rating curves for the streams. The duration of monitoring is at least two years after the completion of contouring. For stream channel integrity and morphology, Table MR-2 addresses channel stability and erosion, channel sinuosity channel profile, and cross sections. The release criteria are: "Stable channel and banks, no significant erosion, or bank undercutting, stream morphology within the range of values appropriate for the designed stream type (Rosgen C or E)." The location of sampling is over the entire channel length and representative cross sections. The frequency of monitoring for channel stability and erosion is after "significant" rain events for at least the first two years after contouring. The frequency of monitoring for channel sinuosity, channel profiles, and cross sections is years 2, 5, and 10. For soils, Table MR-2 addresses substrate description, litter accumulation, and compaction, but lists no release criteria. For vegetation, Table MR-2 addresses the species list and percent cover, FLUCFCS Level III map, percent bare ground and open water, nuisance species cover, upland species cover, tree density, shrub density, tree height, tree breast height diameter starting in year 5, and fruit and seedlings (starting in year 7). The release criteria are 400 trees per acre that are 12 feet tall, 100 shrubs per acre, species richness and diversity within the range of reference forested and herbaceous wetlands, 80 percent groundcover, and less than ten percent nuisance species. The location of sampling is randomly selected sites along several transects across each wetland, and the frequency of monitoring is years 1, 2, 3, 5, and every other year through the year prior to release. For macroinvertebrates, Table MR-2 addresses the number and identity of each taxon, diversity, functional feeding guilds, and the DEP Stream Condition Index. The release criteria are: "Species diversity, richness within range of reference wetlands, all functional feeding guilds or qualify as 'good' or better in the SCI." The location of sampling is in at least one representative 100-meter reach in each stream, and the frequency is at least twice yearly for at least the year prior to the release request for a stream. CRP The introductory CRP narrative describes IMC's plans to reclaim uplands, but does not impose any obligations upon IMC. Instead, the narrative introduces the reclamation project and summarizes the provisions of the general and specific conditions of the CRP. The failure to incorporate Map I-2, whose wetlands were incorporated by the ERP, and Map I-3 is material. CRP General Conditions 8, 9, and 10, discussed below, impose upon IMC certain requirements when reclaiming certain communities, but do not themselves impose the requirement of reclaiming these communities. The same is true for CRP Specific Condition 8. The only subcondition mentioning Map I-2 is Specific Condition 8.c, which alludes to Map I-2 while imposing upon IMC the reclamation technique of backfilling at least 15 inches of sand tailings upon those areas to be reclaimed as temperate hardwoods, live oak, and hardwood-conifer mixed. If this indirect reference imposes upon IMC the obligation of reclaiming these three upland forests pursuant to their depiction on Map I- 2, it is odd that Specific Conditions 8.a and 8.b fail even to mention Map I-2 in their discussion of the sand tailing and topsoil requirements for reclaimed pine flatwoods and sand live oak and xeric oak, especially when these three upland forest communities account for over 400 acres of reclaimed uplands, according to Table 12A1-1, which is also not incorporated into the CRP. The narrative portion of the CRP states that IMC's reclamation plan is to create 1769 acres of pasture, 50 acres of herbaceous, shrub, and mixed rangeland, 273 acres of palmetto prairie, 194 acres of pine flatwoods, 33 acres of xeric oak, 43 acres of temperate hardwood forest, 39 acres of live oak forest, 196 acres of sand live oak forest, and 550 acres of hardwood- conifer mixed forest. The CRP notes that most of the communities in the no-mine area, enhanced areas, and reclaimed communities will form part of a "larger mosaic of diverse upland and wetland habitat associated with Horse Creek and will serve as important wildlife corridors." The failure of the CRP approval to incorporate Map I-2 is an oversight. In the introduction to the January submittal, IMC proposed to reclaim the uplands, by community and area, as enumerated in Table 12A1-1, and, by community and location, as depicted on Map I-2. The failure to incorporate Map I-3 is probably an oversight, based on the second CRP narrative quoted below. The CRP narrative states that IMC has developed a Habitat Management Plan (HMP), which includes detailed pre- mining wildlife surveys and relocation programs. The narrative states that IMC will relocate, disturb the habitat of, and reclaim habitat for Florida mice, gopher tortoises, gopher frogs, and other commensals, pursuant to approvals from FWC. The narrative reports that IMC's Indigo Snake Management Plan has already received approval from the required agencies. Also, IMC will spend at least $30,000 to fund research on the potential of relocating burrowing owls onto reclaimed landscapes and at least $30,000 to analyze amphibian use of natural and reclaimed wetlands. However, the ERP and CRP approval incorporate only parts of the HMP. The CRP narrative adds: In addition to wetlands, a significant portion of the reclamation plan will focus on wildlife habitat through the creation of a diversity of upland habitat types adjacent to the Horse Creek corridor. This will provide a contiguous corridor averaging half a mile wide. IMC has committed to reclaim significant areas of pine flatwoods, palmetto prairie, sand live oak, and other upland habitats well beyond what is required by existing reclamation rules. This will be accomplished mainly through topsoiling and planting of a diversity of native species including shrubs and groundcover species. The use of exotic forage grasses will be minimized and native grass species will be emphasized in the groundcover of reclaimed upland habitat areas. A diversity of shrubs will also be planted in reclaimed upland forest areas. In addition, most of the mitigation wetlands will be created with diverse upland habitats surrounding them, resulting in enhanced wildlife and water quality functions. The CRP narrative addresses reclaimed soils: Special emphasis has also been placed on improving post reclamation soils. . . . Emphasis has been placed on restoring soils to more closely mimic native soils and existing soil horizons by making greater use of native topsoil and incorporating a greater percentage of sand at the surface. Green manure will be incorporated into surface soils where native topsoil is not used. In most cases, existing overburden spoil piles will be graded down and then capped with several feet of sand tailings. The thickness of the sand layer will be determined based on the targeted reclaimed land use with some wetlands requiring additional overburden to restore appropriate hydrology. The CRP narrative acknowledges that IMC has developed an Integrated Site Habitat Management Plan that includes plans for the reclamation of uplands, control of nuisance and exotic species in uplands, and management of all listed species. The CRP narrative asserts that IMC will reclaim and manage over 1378 acres of uplands, such as by removing cogongrass and maintaining it to less than 10 percent coverage, except less than 5 percent coverage within 300 feet of wetlands. The CRP narrative mentions that IMC has "volunteered" the Conservation Easement and Easement Management Plan to encumber not less than 525 acres associated with Horse Creek. CRP General Condition 7 states: "[IMC] is encouraged to implement the Integrated Habitat Network (IHN) concept (where possible) when establishing reclaimed upland and wetland forested areas." As overlaid on OFG, the IHN, which is developed by DEP, is depicted in Figure 12-5. The IHN covers almost all of the no-mine area; the floodplains and headwater wetlands of the Stream 1e series, Stream 3e, and Stream 3e?; much of the non-pasture reclaimed uplands; and a large area of reclaimed improved pasture south and west of the reclaimed sand live oak area immediately west of the West Lobe. The backbone of the IHN is the network of rivers and streams, with their floodplains, that provide multifunctional habitat for wildlife. As noted in the introduction to the January submittal, the HMP helps implement the portion of the IHN located at OFG. Although only selectively incorporated into the ERP and CRP approval, the HMP describes IMC's overall plan for reclaiming OFG. The stated goal of the HMP is "to maintain or improve the biological functions of the wetlands and uplands . . . as an integrated component of the mining and reclamation plans." The HMP adds: "By preserving and managing the highest quality habitats on [OFG], these reserves will serve as source populations to recolonize the remainder of the site following completion of reclamation." Overall, the reclamation plan and HMP try to restore a functional interrelationship of uplands, wetlands, and surface water to replace the reduced functions that result from the agricultural alterations to uplands, wetlands, and most of the surface water, leaving large areas of a patchwork fragmentation of habitats. The HMP covers habitat management prior to land clearing, species-specific management techniques immediately prior to land clearing, species-specific management techniques during mining, habitat management in no-mine areas, reclamation goals for habitat, reclaimed habitat management after release, and, in the second part of the HMP, specific actions for each listed wildlife and plant species. Prior to land clearing, IMC will engage in little active habitat management, apart from surveys, as the Carlton- Smith family continues its agricultural uses of the land, which it is entitled to do under its contract with IMC. Immediately prior to land clearing, IMC will relocate each species, after obtaining the necessary permits, either by capture or, for the more mobile species, controlled burns or directional clearing to encourage wildlife migration into an adjoining refuge area. For listed bird species, IMC will protect their nesting areas or restrict land clearing to non-nesting season. During mining, aquatic- and wetland-dependent species will continue to have access to Horse Creek and its riparian wetlands, which are never isolated by the ditch and berm system. The only permitted direct disturbance of the no-mine area is outside Horse Creek's direct floodplain. During mining, the vast water recirculation system will provide incidental, temporary habitat for many aquatic- or wetland-dependent species. The second part of the HMP identifies management techniques for specific listed species of vertebrates. The HMP states that no listed plants exist on OFG. The HMP addresses 15 listed species observed on OFG and nine listed species that could potentially use OFG. The HMP mistakenly lists the Florida panther in the latter category, rather than the former category, but the error is harmless given the limited use of OFG by the Florida panther and the apparent lack of a breeding population north of the Caloosahatchee River. The following paragraphs describe the HMP's treatment of several listed species using OFG. Noting that the American alligator, which is a species of special concern, occupies freshwater habitats throughout Florida, plenty of such habitats exist around the mining areas, and the alligator is mobile, IMC expects that the American alligator will move out of the way of mining activities, so no management measures will be used for alligators. Presumably well-served by former Land-and-Lakes reclamation and an opportunistic inhabitant of deep wetland reclamation, alligator management is of no importance in these cases. The HMP reports two possible observations on OFG of the Florida panther, which is an endangered species. There is no doubt about one of these observations. On the other hand, there is no doubt that OFG is far from prime panther habitat. Thus, IMC will check for panther signs during pre-clearing surveys and anticipates that the unmined floodplains that are part of the IHM will maintain suitable habitat--presumably, for travel. IMC has already mapped the distribution on OFG of the gopher tortoise, which prefers well-drained, sandy soils characteristic of xeric and mesic habitats. IMC has already prepared a management plan for gopher tortoises, which are a species of special concern, and, upon DEP approval, will engage in several measures to reduce mortality due to mining activities, including, upon receipt of an FWC permit, relocating gopher tortoises, as well as other commensal species found in or near the tortoises' burrows, to appropriate locations, including one or more of the above-described ACIs. The Sherman's fox squirrel, which is a species of special concern, prefers sandhill communities and woodland pastures, and many of these squirrels use suitable areas of OFG. They are mobile, and, during mining operations, they will move to the no-mine areas adjacent to Horse Creek. Prior to land clearing, IMC will survey each area, and, if it finds active nests, these areas will be avoided until the young squirrels have left the nests, pursuant to FWC requirements. The Florida Mouse, which is a species of special concern, inhabits sand pine scrub and other xeric communities and is a commensal of the gopher tortoise. Prior to land clearing of suitable Florida Mouse habitat, IMC will conduct live-trapping. If any such mice are captured, IMC will relocate them to a suitable relocation site, such as to ACI-2, ACI-4, or ACI-6 or to xeric or pine flatwoods/dry prairie habitat that will be reclaimed on OFG. IMC will employ similar procedures for the Florida gopher frog, which is another commensal of the gopher tortoise. A species of special concern, the Florida gopher frog will also be the subject, with other amphibians, of research regarding use of reclaimed habitats and funded by IMC with at least $30,000. The Audubon's crested caracara, which is a threatened species, prefers dry prairie with scattered marshes and improved pasture. They typically nest in cabbage palms or live oak trees. Observers have seen a pair of caracaras on OFG, but attempts to locate a nest onsite have been unsuccessful. Prior to clearing cabbage palms, IMC will again survey the area for nests. If IMC finds a nest onsite or within 1500 feet of OFG, it will develop an FWC-approved management plan. The post- reclamation palmetto prairie and pine flatwoods are good caracara habitat. One of the few listed species whose habitat needs have been well-served by agricultural conversions to improved pasture, the burrowing owl occupies numerous areas on OFG. IMC intends to schedule land clearing in areas with active burrows during non-nesting season, but, if this is impossible, IMC will attempt to empty the burrow prior to clearing the land. Additionally, IMC will spend at least $30,000 to fund research to improve the technology to relocate onto reclaimed land burrowing owls, which are a species of special concern. Although IMC found on OFG no nests of sandhill cranes, which are threatened, or little blue herons, which are a species of special concern, sandhill cranes nest in reclaimed wetlands on the Ft. Green Mine, and IMC expects sandhill cranes to nest in the reclaimed wetlands at OFG. Prior to mining, IMC will survey marshes for sandhill crane and little blue heron nests, and, if it finds any, it will disturb those areas in non- nesting season. Wood storks, which are endangered, use OFG for foraging, but IMC found no evidence of wood stork rookeries on or nearby OFG. The nearest known active rookery is 22 miles from OFG. Prior to landclearing during wood stork nesting season, IMC will survey each wetland with the potential to support stork nesting sites. If IMC finds any nests, it will follow the latest guidelines from FWC or U.S. Fish and Wildlife Service for protecting the site. For the white ibis, snowy egret, and tricolored heron, which are species of special concern, IMC will survey those wetlands that are suitable nesting site prior to landclearing. If any active nests are found, IMC will schedule landclearing during non-nesting season. CRP General Condition 8 provides that groundcover in all upland forests shall include one or more of the following native plants: fruit-bearing shrubs, low-growing legumes, native grasses, and sedges. CRP General Condition 9 provides that IMC shall use native grasses and shrubs when reclaiming grasslands and shrub and brushlands. CRP General Condition 10 provides that IMC shall incorporate clumps of trees in reclaimed improved pasture so that each ten acres has "some trees." CRP General Condition 11 states that IMC shall make "every effort" to control nuisance and exotic species within the mine. CRP Specific Condition 1 is ERP Specific Condition CRP Specific Condition 2 is ERP Specific Condition 23. CRP Specific Condition 3 is ERP Specific Condition 11. CRP Specific Condition 4 is for IMC to obtain authorization from the FWC to trap and relocate Florida mice. Specific Condition 4 requires the trapping and relocation of Florida mice prior to clearing areas inhabited by them. CRP Specific Condition 5 requires IMC to make "every effort" to relocate listed plant species to suitable reclamation sites when such species are encountered prior to or during land clearing. CRP Specific Condition 6 is ERP Specific Condition 12.c. CRP Specific Condition 7 is ERP Specific Condition 12.d. CRP Specific Condition 8.a provides: Areas designated as pine flatwoods . . . and palmetto prairie shall be reclaimed by placing a minimum layer of fifteen (15) inches of sand tailings over the overburden and topsoiling with three (3) to six (6) inches of direct transferred or stockpiled native topsoils from pine flatwoods or palmetto prairie areas as that topsoil is available and feasible to move. Feasible means of good quality, relatively free of nuisance/exotics species, and within 1.5 miles of the receiver site. If topsoil is not available or feasible to move, a green manure crop will be seeded and disked in after it has matured before applying a flatwoods or palmetto prairie native ground cover seed mix to this site. In flatwoods, longleaf pine . . . or slash pine . . . shall be planted in the appropriate areas to achieve densities between 25 and 75 trees per acre. In flatwoods and palmetto prairie, shrubs typical of central Florida flatwoods and palmetto prairies will be recruited from the topsoiling, planting, and/or seeding to achieve a minimum average density of 300 shrubs per acre. The total vegetation covered by hydric flatwoods will be greater than 80 percent, in mesic flatwoods and palmetto prairies will be greater than 60 percent, and in scrubby flatwoods, greater than 40 percent. CRP Specific Condition 8.b provides: Areas designated as sand live oak or xeric oak scrub . . . shall be reclaimed by placing several feet of sand tailings over the overburden and topsoiling with three (3) to six (6) inches of direct transferred or stockpiled native topsoil from scrubby flatwoods or scrub areas. Feasible means of good quality, relatively free of nuisance/exotics species, and within 1.5 miles of the receiver site. If topsoil is not available or feasible to move, a green manure crop will be seeded and disked in after it has matured before applying a scrubby flatwoods or scrubby native ground cover seed mix to this site. Trees and shrubs typical of central Florida scrubs will be recruited from the topsoil, planted, and/or seeded to achieve a minimum density of 600 plants per acre. Vegetative cover in these areas will be greater than 40 percent. CRP Specific Condition 8.c provides: Other upland forest areas, including [temperate hardwoods, live oak, and hardwood-conifer mixed], shall be reclaimed, as illustrated by Map I-2, by placing a minimum layer of fifteen (15) inches of sand tailings over the overburden, capping the area with approximately three (3) inches of overburden and disking the surface to reduce compaction of the upper soil layer prior to revegetation. Other uplands shall be revegetated with a native ground cover, planted with trees to achieve a density of 200 plants per acre, and planted with shrubs to achieve a density of 200 shrubs per acre. CRP Specific Condition 8.d provides that IMC shall incorporate native grass species into the groundcover of all reclaimed uplands. CRP Specific Condition 8.e allows IMC to use bahia grass, Bermuda grass, and exotic grass species as groundcover in native habitats only in "limited amounts" needed for "initial stabilization in areas highly prone to erosion." When using these grasses, IMC must maintain them to prevent their proliferation. CRP Specific Condition 9 is ERP Specific Condition CRP Specific Condition 10 is ERP Specific Condition 21. CRP Specific Condition 11 resembles ERP Specific Condition 11, but requires more of IMC. CRP Specific Condition 11 states that IMC "has committed" to initiate the management and evaluation of amphibians, including the Florida gopher frog, and shall adhere to the provisions of the IMC Minewide Gopher Tortoise and Burrow Conceptual Management Plan. IMC shall pay at least $30,000 to conduct a study of amphibian use of reclaimed and unmined wetlands. IMC shall report its progress in the annual narrative reports that it must file, pursuant to Florida Administrative Code Rule 62C-16.0091. CRP Specific Condition 12 contains similar provisions for the burrowing owl. Related to ERP Specific Condition 15.a, CRP Specific Condition 13 requires IMC to make "every effort" to control cogongrass by eradicating it prior to mining, removing it after it colonizes spoil piles during mining, inspecting donor topsoil sites to prevent infestation by it, and regularly treating it on reclaimed sites to maintain coverage below 10 percent, or 5 percent within 300 feet of any reclaimed wetland. WRP The WRP at issue is for the Ft. Green Mine, not OFG. The basic purpose of the WRP is to permit IMC to dispose of the clay tailings extracted from OFG in CSAs O-1 and O-2, which are located at the southern end of the Ft. Green Mine. In an unchallenged action, DEP, on March 20, 2001, approved a requested modification of the CRP approval for the Ft. Green Mine to permit the changes sought in these cases for the Ft. Green Mine WRP. Thus, the WRP modification sought in these cases is merely a conforming modification. Normally, a WRP/ERP would take precedence over a CRP approval because mining may not start without a WRP/ERP, but may start without a CRP approval. In the unusual situation at the Ft. Green Mine, where the mining has been completed, the analysis of the WRP modification is limited to, primarily, the sufficiency of the changes in mitigation to offset the already- completed mining and, secondarily, the relevant impacts of the mitigation itself. DEP issued the WRP on May 1, 1995. This permit allowed IMC to mine 524.6 acres of wetlands at the Ft. Green Mine. On February 3, 1997, DEP issued an ERP to allow IMC to disturb 1.39 acres of surface water for a utility corridor. Following the receipt of a request by IMC for a major modification of the WRP to permit the mining of 7.6 acres of wetlands, DEP consolidated this request, the utility-corridor ERP, and the original WRP into a new WRP issued July 28, 1999. After a modification to the new WRP in 2000 that is irrelevant to the present cases and other irrelevant permitting activity, IMC has requested the modification that is at issue in these cases. Because this WRP modification follows the completion of mining and the near-completion of backfilling of sand tailings into the mine cuts, a denial would not spare the wetlands and other surface waters from the impacts of mining. Rather, a denial would leave the Ft. Green Mine with greater impacts and less mitigation. In simplest terms, a denial would harm the water resources of the District. Strengthening the already-approved mitigation and diminishing the impacts of the already-approved CSAs, this WRP modification will authorize IMC to reduce the size of the two CSAs (O-1 and O-2) in the southern end of the Ft. Green Mine and relocate them farther from Horse Creek; to relocate several reclaimed wetlands in the vicinity of CSAs O-1 and O-2 and expand their area by 2.7 acres with minor changes to some sub- basin boundaries; and to modify the reclamation schedule to conform to a modification already approved without challenge for the Ft. Green Mine CRP. The record demonstrates that the reduction in size and relocation of the CSAs away from Horse Creek will reduce the hydrological and biological impacts from those already permitted. The record demonstrates that the expansion of the area of reclaimed wetlands will add mitigation to offset the hydrological and biological impacts from already-completed mining activities. The record demonstrates that the relocation of the reclaimed wetlands and modification of the reclamation schedule will not affect the impacts or mitigation. Other Mitigation/Reclamation Projects Introduction The formation of wetlands vegetation, according to IMC biologist Dr. Andre Clewell, is a function of topography, hydrology, soils, and physical environment--to which should be added time. The formation of soils, according to Charlotte County soil expert Lewis Carter, is a function of parent material, time, relief, vegetation, and climate. Hydrology is dependent upon, among other things, topography, soils, geology, vegetation, and climate. Successful reclamation must thus account for the complex interdependency of the dynamic processes involving vegetation, soil, and hydrology. Although actual reclamation follows a clear order-- geology, soils, contouring, and planting--the order of the design process is not so clear. Presumably, in designing a reclamation plan, the biologist, soil scientist, and hydrologist would each prefer to have the final--as in last and authoritative--word. In general, the comparison of older mitigation sites to newer mitigation sites requires caution due to two factors, which somewhat counterbalance each other. The vegetation of the older sites has had longer to establish itself. The importance of this factor varies based on the type of vegetation. Groundcover establishes more quickly than shrubs, and shrubs establish more quickly than trees, but groundcover that requires protection from the tree canopy may not be able to colonize an area until the trees are well-established. Soils take a longer time to recover, generally longer than the timeframes involved in phosphate mining reclamation in Florida. The soils present in Hardee County took 5000 to 10,000 years to form. The A horizon, or topsoil layer, at OFG formed over 300-500 years. However, if the soil and hydrology are suitable at a reclaimed site, an A horizon may start to reform in as little as 10 years, but, even under ideal conditions, it will take several hundred years to reform to the extent and condition in existence prior to mining. The mucky soils underlying bay swamps form at the rate of about one inch per 1000 years. Offsetting the advantage of age for vegetation and soils, the older reclamation sites may suffer from less advanced designs and construction techniques. Newer sites benefit from advances in science and technology that have enabled phosphate mining companies to design and implement reclamation projects that more successfully replace the functions of the natural systems and communities lost to mining. Some of these advances have resulted in dramatic, sudden improvements in reclamation. The assessment of past reclamation projects must account, not only for the age of each project, but also the willingness of the phosphate mining company at the time to employ the then-available science and technology. The ratio of the cost of reclamation to projected revenues depends on the variables of specific mitigation expenses, mining expenses, and the value of the phosphate rock. These economic factors operate against the backdrop of a dynamic regulatory environment. In these cases, for example, IMC's willingness to reduce its mining impacts and expand its mitigation was a direct result of the Altman Final Order and DEP's decision to revisit its earlier decision to permit the Ona Mine. Uplands The uplands at OFG are more amenable to successful reclamation than the wetlands or streams at OFG. Uplands provide crucial functions. Certain uplands, such as those that provide seepage to wetlands or prime recharge to deep aquifers, provide hydrological functions as complex as the hydrological functions of many wetlands. Certain uplands provide irreplaceable habitat. Certain uplands vegetation is as vulnerable to climactic or anthropogenic disturbance as any wetlands vegetation. However, for the most part, the functions of uplands are not as complex or important as the functions of wetlands and other surface waters, when examined from the perspective of the water resources of the District, and these functions are more easily reclaimed. Over 77 percent of OFG and over 90 percent of the uplands at OFG are agricultural (2146 acres) or pine flatwoods, palmetto prairie, or sand live oak (1120 acres). (As noted above, palmetto prairie and sand live oak share many attributes of pine flatwoods, which they often succeed.) In terms of function, tolerance to ranges of hydrology and soils, and robustness of post-reclamation vegetation, these 3266 acres of uplands communities will be easier to reclaim than all of the proposed streams and wetlands, except for deep marshes, although pine flatwoods and palmetto prairies present the greatest difficulties in uplands reclamation due to their soil and hydrological requirements, including access to the post- reclamation water table. Impacts to uplands include the disappearance--even temporarily--of critical habitat for listed species, the susceptibility of uplands to post-disturbance nuisance exotics, and, for upland forested communities, the relatively long period required for restoration of the canopy. However, these impacts can be offset in most cases. Management plans can mitigate the temporary or permanent loss of specific upland habitat, depending on the availability of habitat and the robustness and abundance of the species requiring the habitat. Absent the presence of rare uplands habitat and/or rare species requiring the habitat, a greater problem with uplands reclamation is controlling nuisance exotics. Various grass species, including Bahia, Bermuda, torpedo, centipede, Natal, and cogon, impede progress in the development of a healthy uplands community. One of the world's ten worst weeds, cogongrass is limited to uplands, although it may extend into the higher parts of wet prairies and drier areas within forested wetlands. Although nuisance and exotic species may invade undisturbed areas, the removal of existing upland vegetation exacerbates the problem by removing native competitors and stimulating unwanted germination. However, ongoing maintenance, through a combination of herbicides, manual removal, and fire, controls the nuisance exotics long enough that the native vegetation can colonize the disturbed area. Upland forested communities require protection from grazing and mowing to permit their establishment. Canopy development takes years for any upland forested community and, for slower-growing xeric systems, at least a decade. The timely restoration of an appropriate fire regime is also important for the health of many upland communities. Not surprisingly, the record demonstrates the successful reclamation of uplands at several mitigation sites. In recent years, reclamation scientists have restored uplands structure of uplands by restoring the understory and midstory. Uplands restoration has improved with the introduction of new, more effective reclamation techniques, such as topsoiling and seeding. Until 1987, for instance, restoration biologists did not know that wiregrass--a key component of the understory of pine flatwoods--produced seeds. This knowledge has assisted in the reclamation of a proper understory of pine flatwoods. The favorable prognosis of uplands reclamation means that extensive areas of OFG uplands may be mined. Their functions will be substantially replaced, in a reasonable period of time, upon the establishment of the reclaimed upland community, although the destruction of xeric communities means their absence for relatively long periods of time and the destruction of uplands providing seepage support to wetlands requires the close-tolerance hydrology and soils associated with the most difficult wetlands reclamation. Approved in 1989 and amended in 1994, constructed by 1986, and released in 1994, Best of the West (NP-SWB(1D)) was targeted for 15-18 acres of xeric habitat. Best of the West was constructed on sand tailings overlaying overburden, although this site exhibits some stunted vegetative growth where the sand tailings may not be very thick and the roots of trees may have encountered the hardened overburden. FWC assisted the phosphate mining company in designing the reclamation plan for this site, which has resulted in the successful reclamation of 10 acres of xeric habitat. The CDA provides some background on Best of the West. The West Noralyn Xeric Scrub Reclamation (N-5), which was constructed by 1986, contained "mulched overburden plots" and 60 acres of unmined scrub. Containing a total of 462 acres of reclaimed and unmined land, Noralyn was the first attempt to create a large-scale xeric community. About 120 acres of Noralyn received 12 inches of donor topsoil from a comparable xeric community. Due to a lack of representation in the donor site, supplemental plantings of longleaf pine, sand pine, and rosemary followed. The overall project has been "moderately successful," but the 18 acres that yielded "exceptional results" were dubbed "Best of the West." Best of the West thus illustrates a recurrent feature of much reclamation activity, in which successful projects are actually small parts of the original project area, the rest of which is substantially less successful. The CDA states that, in January 2000, IMC initiated a land management program for Noralyn that includes herbicide applications and prescribed burns. After herbicide was applied to kill cogongrass, IMC conducted the first burn in March 2001. Noralyn is now being managed for four to five families of Florida scrub jays, a listed species. Four Eastern Indigo snakes, 225 gopher tortoises, numerous gopher frogs, and 119 Florida mice have been relocated to Noralyn. Approved in 1988, constructed in 1991, and released in 1992, Hardee Lakes topsoil (FG-PC(1A)) has a 7.9-acre uplands component that was topsoiled with one inch over overburden. Despite receiving no maintenance, the site displays few weeds or nuisance exotics, although cogongrass has invaded the site. The reclaimed site displays saw palmetto, gallberry clumps, creeping bluestem grass, and, in topsoiled areas, flowering milkwood. The site includes an ecotone between pine flatwoods and a wet prairie, which developed due to the appropriate slope and soil. The CDA identifies two one-acre demonstration projects with Hardee Lakes topsoil. The Ft. Green-Hardee Lakes Pine Flatwoods Project, a topsoiled site, has achieved a lower ratio of saw palmetto to pines than is presently typically of fire-suppressed communities and is more typical of historic Florida pine flatwoods. The Ft. Green-Hardee Lakes Palmetto Prairie Site, also topsoiled, has been successfully revegetated with saw palmettos and other appropriate species. An interesting uplands reclamation site, for its different use of soils, is the Bald Mountain complex (KC-LB(2) and LB(4)), which is a 180-acre site. In a reclamation project approved in 1989 and 1996, constructed in 1993, and released in 1994 and 2002, IMC backfilled the Bald Mountain site with sand tailings down to 40 feet, capped the sand tailings with six inches of overburden, and then mixed the soils. Nearby, Little Bald Mountain received only sand tailings. Scrub were planted on both locations, but Bald Mountain also received sandhill plantings. Bald Mountain contains suitable sandhill species, such as sandhill buckwheat, although natal grass has been a problem. Natal grass is an invasive grass that colonizes quickly and often requires manual removal. Little Bald Mountain contains appropriate understory grasses, including short-leaved rosemary, an endangered species; Gopher apple, an important wildlife food; and Ashe's [savory] mint, a listed species. The rosemary and mint are reseeding themselves. The site also contains several large palmettos that were started from seed. Approved in 1996, constructed in 2000, and not yet released, Ft. Green/Horse Creek Xeric (FG-HC(3 & 5)) is a 99-acre uplands site reclaimed as xeric oak. IMC backfilled at least six feet of sand tailings over the overburden and then added topsoil over the sand. Already, this site, which is in the nearby Ft. Green Mine, has developed all levels of structure in the appropriate ecosystem, although, according to the CDA, it received irrigation "frequently" from an irrigation system at the start of the project. The site includes denser vegetation, such as shrub palmetto, grasses, and forbs. The direct transfer of topsoil has added species diversity, such as a Florida spruce and a listed orchid. The site also contains a small number of longleaf pines. IMC has hand-removed natal grass at this site, but has lately been using a new selective herbicide. According to the CDA, though, the presence of invasive exotics throughout the site is limited to 0.4 percent. One of the best upland reclamation sites is MU 15E Topsoil (FCL-LMR(6)), which was approved and constructed in 2002 and has not been released. This is a 30-acre topsoiled site in which IMC transferred topsoil carefully: if topsoil was taken from a depression on the donor site, the topsoil was placed in a depression in the receiving site. This site already displays a rich diverse plant palette with hardly any weedy or exotic species. In this site, palmetto and wet prairies slope down to a flatwoods marsh. This site also contains a reclaimed ephemeral wet prairie--possibly the only known ephemeral wet prairie ever reclaimed after phosphate mining. With modest efforts regarding soils and possibly more strenuous efforts regarding nuisance exotics, the reclamation of uplands is relatively easily attained, provided the sites can be protected for the longer timeframes necessary to establish upland forests and especially upland xeric communities and an appropriately shallow water table is reclaimed for pine flatwoods and palmetto prairies. Wetlands Wetlands reclamation is generally more difficult than uplands reclamation. Successful wetlands reclamation typically requires better command of post-reclamation topography, hydrology, soils, and physical environment. Material deviations in these parameters reduce, or eliminate, many wetlands functions, such as floodplain communication, nutrient sequestration, floodwater attenuation, ecotone transitions, and habitat diversification. The loss of such functions may result in immediate problems with water quality, water quantity, and habitat. Given the greater difficulty in successful wetlands reclamation, experience in wetlands reclamation is, not surprisingly, more mixed than the generally favorable experience in uplands reclamation. The greater difficulty in, and more guarded prognosis of, wetlands reclamation, as compared to uplands reclamation, means that the disturbance of wetlands demands closer analysis of the functions of the wetlands proposed to be mined, the functions of the wetlands proposed to be reclaimed, and the reclaimed soils, hydrology, topography, and physical environment on which the reclamation scientists will rely in reclaiming wetlands functions. The most important factor in wetlands reclamation is hydrology. Wetlands with less rigorous hydrological needs, especially if they also tolerate deeper water over longer periods of time, reclaim much more easily than wetlands with more precise hydrological needs, especially if they require shallower water over shorter periods of time. The phosphate mining industry has repeatedly reclaimed marshes and cypress swamps that are inundated deeply and for extended periods of time, but has had a much harder time reclaiming shallower wetlands requiring shorter hydroperiods or shallower water levels. The two most difficult wetlands of this type to reclaim are bay swamps and wet prairies. Among herbaceous wetlands, deep marshes are the easiest to reclaim. Often a target of Land-and-Lakes reclamation, deep marshes also are the result of reclamation projects that failed to create targeted shallower wetlands. Charlotte County ecologist Kevin Irwin noted that deep marshes are easier to reclaim than forested wetlands, for which the post-reclamation hydrology must be more precise. Similarly, a freshwater marsh, which tolerates 6-30 inches of water from 7-12 months annually, is easier to reclaim that a wet prairie, which tolerates 0-6 inches of water from 2-8 months annually. Among forested wetlands, bayheads or bay swamps, as defined in these cases as seepage forested wetlands, are harder to reclaim than mixed wetland hardwoods, as IMC biologist Dr. Douglas Durbin testified--likely, again, due to the requirement of more precise post-reclamation hydrology. Accordingly, the parties do not dispute the ability of the phosphate mining industry to reclaim deep marsh habitat, including freshwater marshes and shrub marshes, as well as deep swamps--principally cypress swamps. Like wet prairies, which sometimes fringe deep marshes, deep marshes provide habitat, supply food, attenuate floodwaters, and improve water quality. Deep marshes may host large numbers of different plant species. However, like lakes, deep marshes remove larger amounts of water from the watershed, as compared to shallower wetlands with shorter hydroperiods, due to evapotranspiration. The reclamation projects known as Morrow Swamp, Ag East, 8.4-acre Wetland, and 84(5) trace a short history of the reclamation of deep-marsh habitat. Permitted in 1980, constructed in 1982, and released in 1984, 150-acre Morrow Swamp represents a prototype, second- generation wetlands reclamation project. According to the CDA, Morrow Swamp is from an era in which reclamation did not attempt to restore topography: "This ecosystem included the reclamation of 150 acres of wetland (freshwater marsh, hardwood swamp, and open water) and 216 acres of contiguous uplands. The reclamation site was originally pine flatwoods and rangeland before it was mined in 1978 and 1979." Designed and built before reclamation scientists concentrated on soils, the hydrological connection between Morrow Swamp and Payne Creek, into which Morrow Swamp releases water, is a concrete structure in a berm that leads to a swale that empties into Payne Creek. Morrow Swamp reveals one obvious shortcoming of mechanical outflow devices, at least if they depend on ongoing maintenance, because vegetation and sedimentation in the infrequently maintained outflow device have blocked the flow of water and contributed to water levels deeper than designed. The reclamation scientists pushed the row-plantings of trees in Morrow Swamp in an effort to understand the relationship of vegetation and hydroperiod. In doing so, they killed thousands of trees, such as the cypress trees that Authority ecologist, Brian Winchester, found that grew to 6-8 inches in diameter and suddenly died. This tree mortality was likely due to problems with water depths and hydroperiods, as suggested by the healthier cypress trees lining the shallower fringe of the marsh. Morrow Swamp operates as a basin with a perched water table atop compacted, relatively impermeable overburden. Beneath the dry overburden is moist soil, so there is no groundwater connection between the marsh and the surficial aquifer. According to Mr. Carter, sand is 15 times more permeable than overburden. Morrow Swamp presents numerous shortcomings, but not to alligators, who find ample food and habitat in and about the deep marsh. More importantly, the emergent-zone vegetation within Morrow Swamp is sequestering nutrients and thus providing water-quality functions. Unfortunately, the deeper water supports only floating vegetation, which is much less efficient at sequestering nutrients, and less diverse than the shallower emergent vegetation, so the excessive depths of Morrow Swamp limit its water-quality functions. Although short of a model wetlands reclamation project, Morrow Swamp was an important milestone in the development of wetlands reclamation techniques and clearly functions as a deep shrub marsh today. Permitted in 1985, constructed in 1986, and released in 2002, 214-acre Ag East (PC-SP(1C)) was built on the knowledge acquired from Morrow Swamp. At Ag East, which is just northeast of Morrow Swamp, the reclamation scientists, planting a large variety of trees, focused on water levels and hydroperiods. The reclamation scientists engineered a wetland system with less open water than Morrow Swamp. They also inoculated the surface with a layer of organic mulch material 2-4 inches thick. However, the design of Ag East again incorporated mechanical devices to control water levels. A weir at one corner of Ag East contains boards; by removing or adding boards, reclamation scientists could control the water depths behind the weir. The deep marsh within Ag East is excessively deep with an excessively long hydroperiod. In certain respects, Ag East has functioned better than Morrow Swamp, although there is some question as to vegetative mix establishing the site and the associated functions that the vegetation will provide. Again, though, Ag East features a functioning deep marsh. One clear shortcoming of Ag East was the failure to create appropriate upland habitat, such as pine flatwoods, around the wetlands, so that wetland species could find appropriate uplands habitat for breeding, nesting, or feeding. The CDA notes the availability of quarterly water quality monitoring data, over a five-year period, for pH, dissolved oxygen, conductance, and total phosphorus, among other parameters, but the results are not contained in this record. Permitted in 1983, constructed by 1986, and released in 1995, 8.4-Acre Wetland (FG-83(1)), which was targeted for 8.4 acres of wetland forested mixed, represents an early use of topsoil, which was a good seed source for herbaceous species and helped increase the effective depth of overburden. As noted above, shallower overburden discourages tree growth past a certain stage. However, 8.4-Acre Wetland also uses a water- control weir to control water depths on the reclaimed wetland. Despite its smaller size than Morrow Swamp or Ag East, 8.4-Acre Wetland was a more ambitious project hydrologically, as it attempted to replace a seepage wetland with a seepage wetland that would receive water from the surrounding uplands. Unlike Morrow Swamp and Ag East, 8.4-Acre Wetland was designed to reclaim only forested wetlands, not forested wetlands and marsh wetlands. Unfortunately, 8.4-Acre Wetland did not re-create a seepage wetland due to excessively deep water and excessively long hydroperiods. Emphasizing instead the creation of microtopography, the reclamation scientists added sand-tailings hummocks within the deeper marsh, effectively lowering the water table under the mound, and planted wetland herbaceous and forested species that could not tolerate the wetter conditions around the hummock. The evidence is conflicting as to the success of these hummock plantings, but the idea was sound. Parts of 8.4-Acre Wetland are at least half infested with cattails, and sizeable areas within 8.4-Acre Wetland are reclaimed marsh, not swamp--despite the attempt of the reclamation scientists to reclaim forested wetlands only. Permitted in 1985, constructed by 1987, and released in 1998, 84(5) (FG-84(5)) was targeted for 17.1 acres of wetland forested mixed and 2.3 acres of freshwater marsh. This site is notable for its soil characteristics. After two soil borings, Mr. Carter could not find a water table in the first 80 inches beneath the surface. However, he found an A horizon, but the CDA notes that this site received 18 inches of donor topsoil. Even more recent reclamation projects have tended to yield deep marshes. Permitted in 1997, constructed in 2002, and not yet released, 198-acre P-20 (FG-HC(9)) exists behind the berm that remains from the ditch and berm system that existed during mining. The sole outlet of the marsh is a discharge pipe, which, presently clogged with vegetation, appears to be contributing to excessively high water depths and excessively long hydroperiods, resulting in an abrupt transition from marsh to uplands without the zonal wetlands associated with natural transitions from marsh to uplands. Water in the marsh spreads into the surrounding uplands, which are planted with upland trees. The berm also prevents natural communication between the marsh and the floodplain of Horse Creek, which is a short distance to the west of P-20. In the reclamation projects described above, more often than not, the reclamation scientists reclaimed deep marshes while targeting shallower wetland systems or at least shallower marshes or swamps. By the mid-1980s, wetlands reclamation scientists were addressing more closely hydrology, vegetation, topsoil, and surrounding upland design, and DEP was imposing post-reclamation monitoring requirements on the phosphate mining companies. One common feature of most of these deep-marsh reclamations is their reliance upon artificial drainage outlets. Inadequate or nonexistent maintenance of these outlets causes excessive water depths for excessive periods. Additionally, reliance on artificial drainage outlets betrays the choice not to attempt more sophisticated design and more precise contouring of the post-reclamation landscape. Improvements in the design and execution of contouring could produce relief from the deep- marsh tendencies of reclamation practices in at least three ways: by flattening the slopes of the edges of the marshes to encourage the formation of more emergent vegetation and wet prairie fringes; introducing a more irregular microtopography in the submerged bottom, including hummocks, to develop greater habitat diversity; and engineering and grading more closely the topographical outlets of marshes, instead of relying on manmade drainage devices that required more maintenance than they received, to better reproduce pre-mining drainage features and access effectively the reclaimed water table. After 8.4-Acre Wetland, reclamation scientists produced, in addition to the P-20s, other marshes with better fringes, so as to support wet prairie fringes, but the most, and evidently only, successful example of shallow-wetland reclamation over an extensive area is PC-SP(2D) (SP-2D). Permitted in 1988, constructed in 1992, and released in 1998 (wetlands), SP(2D) comprises 97 acres of forested and herbaceous wetlands. According to Mr. Winchester, SP-2D exhibits a more natural hydroperiod than the other reclaimed wetlands that he studied. Mr. Winchester visited SP-2D during the dry season, and the shallow wetland was appropriately dry, even though other reclaimed wetlands at the time were inappropriately wet. Mr. Winchester also found less than ten percent coverage by exotic vegetation. Wet prairie fringes deeper marsh at SP-2D, rather than forming larger areas of isolated or connected wet prairie, but this wetland achieves extensive shallow-water areas. According to Authority ecologist Charles Courtney, the marsh of SP-2D appears fairly healthy and contains appropriate vegetation. SP-2D contains sawgrass and forbs, including maidencane and duck potato. Crayfish occupy the wet prairie fringe and are eaten by white ibis and otter. The marsh zonation found at SP-2D is partly a result of appropriate soil reclamation. Mr. Carter found good communication between the shallow marsh at SP(2D) and the surficial aquifer. In the wet season, Mr. Carter found the water table at eight inches above grade, demonstrating that the dry conditions found by Mr. Winchester during the dry season did not extend inappropriately into the wet season. Mr. Carter determined that the first four inches of the wetland is mulched topsoil overlying at least four feet of sand tailings. The subsurface soils were appropriately saturated. Permitted in 2002, constructed in 2003, and not yet released, 1.3-acre FCL-NRM(1) (Regional Tract O, ACOE #362) also contains wet prairie vegetation, but the value of this site, for present purposes, is limited by two factors: its age and its use of a technique not proposed for OFG. Regional Tract O, ACOE #362, is a new site that showcases the success--one year after planting--of the technique of cutting wet prairie sod at a donor site and laying it at the recipient site. Sod-cutting is a good technique, earlier used at Morrow Swamp, but is more expensive than the topsoil transfer proposed for OFG. The reclamation of forested wetlands has improved in recent years. To some extent, the history of forested-wetlands reclamation tracks the path of herbaceous-wetlands reclamation: deeper water for longer periods followed by instances of shallower water for shorter periods. Early in the forested-wetlands reclamation process, reclamation scientists and phosphate mining companies favored cypress trees due to their tolerance of a wider range of water depths and hydroperiods than other wetland trees. However, cypress trees do not occur naturally in the forested wetlands being mined in this part of Florida. Over time, reclamation scientists deemphasized the number of species of wetland trees and emphasized instead species that corresponded to those in comparable forested wetlands. Herbaceous and forested wetlands present different reclamation challenges due to the time each type of wetland requires for revegetation. An herbaceous wetland takes 1-2 years to revegetate, but a forested wetland may take 1-2 decades to gain "really good structure," as Dr. Clewell testified. In addition to taking longer to establish than herbaceous wetlands, forested wetlands require two stages of plantings because the groundcover cannot be added until 4-5 years after planting the trees, so that the trees provide sufficient cover for the appropriate groundcover to grow. The hydrological requirements of different forested wetlands vary. IMC will be reclaiming mostly mixed wetland hardwoods (44 acres), bay swamps and wetland forested mix (each 18 acres), and hydric pine flatwoods (15 acres). All of these communities require water depths equal to those required by wet prairies. Hydric pine flatwoods have a very short hydroperiod-- shorter even than the wet prairie. Bay swamps have a long hydroperiod, comparable to that of the freshwater marsh. And mixed wetland hardwoods and wetland forested mix have hydroperiods roughly equal to that of the wet prairie. The dryness required by mixed wetland hardwoods, wetland forested mix, and especially hydric pine flatwoods make them difficult to reclaim. At first glance, the longer hydroperiod of the bay swamp would seem to make it easier to reclaim, among forested wetlands, but two factors make the bay swamp the most difficult of forested wetlands to reclaim. First, as defined in these cases, the bay swamp provides a critical seepage function, which is hard to create because of its reliance on a precise reclamation of topography, hydrology, and soils, at least with respect to the soil-drainage characteristics. Second, the mucky soils of the bay swamps are difficult to reclaim, given their slow rate of formation, as noted above. Thus, even without the requirement of the dominance of bay trees within the bay swamp, as defined in these cases, bay swamps are very difficult to reclaim, as reclamation experience bears out. An early reclaimed forested wetland is 4.9-acre Bay Swamp (BF-1), which was created on land that had been cleared, but at least large portions of it were never mined, so, except possibly for a disturbed A horizon, the pre-mining soils and site hydrology were intact. Permitted under a predecessor program in 1979, constructed by 1980, and released in 1982, Bay Swamp earned restrained praise from the Authority as, with Dogleg Branch, one of the two highest-functioning reclamation sites. This praise is quickly conditioned with the warning that Bay Swamp did not reclaim as a bay swamp, but as another type of forested wetland, albeit a relatively high functioning one. For all these reasons, Bay Swamp is of limited relevance in evaluating the success of forested wetlands reclamation projects. However, in commenting upon Bay Swamp, the CDA offers some insight into the evolution of reclamation design standards and objectives and the optimism of reclamation scientists when it notes the difficulty of establishing loblolly bay-dominated swamps, "apparent[ly because they require] perennially moist, or wet, soil that is not inundated. Heretofore, these moisture conditions have not been specified as an objective in reclamation design. If these moisture conditions were targeted for reclamation, loblolly bay swamp creation would likely become routine." Another candidate for a reclaimed bay swamp is Lake Branch Crossing (BF-ASP(2A)). Permitted in 1993 and modified in 1997, constructed in 1996, and not yet released, 13.4-acre Lake Branch Crossing contains numerous sweet bays, loblolly bays, and black gums. However, this site was replanted with 4000 trees in mid-2002, and over one-quarter of these trees are displaying signs of stress, so they may not survive. Lake Branch Crossing is bound by a berm with culverts, which may not share a common elevation. Lake Branch Crossing is another excessively deep wetland with an excessively long hydroperiod. Although Lake Branch Crossing exhibits some seepage, it derives its water from a nearby CSA with a much-higher elevation and thus does not compare to the seepage systems to be reclaimed at OFG. The final candidate for a reclaimed bay swamp is Hardee Lakes (FG-PC(1A)), which is a 76-acre wetland forested mixed at the top of the Payne Creek floodplain. Permitted in 1989 and modified in 1994, constructed by 1991, and released in 2000, Hardee Lakes (which is not Hardee Lakes topsoil--the uplands site described above) contains a narrow seepage slope between the berm along the edge of a reclaimed lake and the natural Payne Creek floodplain. Although Hardee Lakes contains some bay trees and operates as a seepage wetland, the setting is inapt for present purposes, given the narrow slope descending from the nearby reclaimed lake, which provides the water for the seepage system. Like Lake Branch Crossing, Hardee Lakes presents an unrealistically easy exercise in the reclamation of a seepage slope and is therefore irrelevant to these cases. At OFG, broader seepage slopes will receive much of their water from upgradient groundwater that is not derived from a lake or other surface water, so the reclamation scientists must reclaim more accurately the topography, hydrology, and soils, again, at least with respect to soil-drainage characteristics. Reclamation scientists monitored Hardee Lakes following reclamation. Besides the seepage slope described in the preceding paragraph, Hardee Lakes contains shallower wetlands, including productive wet prairie and mixed wetland hardwoods that are growing without the need of hummocks, but these areas appear to be more isolated than extensive. As IMC restoration ecologist John Kiefer noted, shallow swamps are better than deep swamps. Again, the tendency toward deeper reclaimed systems, even recently, has plagued reclaimed forested wetlands, such as Lake Branch Crossing, as it has plagued reclaimed herbaceous wetlands. Permitted in 1992 and modified in 1998, constructed in 2002, and not yet released, North Bradley (KC-HP(3) and PD-HP(1B)) was reclaimed for 12 acres of wetland hardwood forest, 21 acres of wetland conifer forest, and 87 acres of herbaceous marsh. North Bradley suffers from poor communication with its water table, as evidenced by Mr. Carter's discovery of a perched water table under the marshes and an excessively deep water table, at 48 inches, under the forested wetlands, as compared to a water table at 40 inches under the uplands. Although the marsh is present, the forested wetland is largely absent. The SP(2D) of forested reclamation projects is Dogleg Branch (L-SP(12A)). The 19.8-acre wetland component of Dogleg was targeted exclusively for wetland hardwood forest. Another 83 acres of Dogleg was reclaimed as upland hardwood forests. Permitted in 1983, constructed by 1984, and released in 1991 (uplands) and 1996 (wetlands), Dogleg's hydrology is better, as one reclaimed area reveals seepage from a mesic area sheetflowing into the stream channel, which was also reclaimed and is discussed in the following section. Due to its proximity to the reclaimed wetlands, this mesic area was probably part of the reclaimed uplands. According to the CDA, Dogleg received transfers of its own mulch and received several phases of tree plantings over several years. The CDA notes that Dogleg was the first forested wetland mitigation project under Florida's dredge and fill rules. Trees were established in part by the transplanting of rooted tree stumps. Forest herbs and shrubs and mature cabbage palms were transplanted from nearby donor sites. Despite these and other efforts, according to the CDA, "design flaws attributable to a lack of prior restoration experience required costly mid-course corrections." Due to high tree mortality, trees had to be replanted over 11 years. The CDA concludes that the problem was a depressed water table due to nearby ongoing mining operations--if Dogleg had a ditch and berm system, it certainly did not have recharge wells. Following mining, according to the July 1995 semi-annual report, over 30 acres of mine pits immediately east and north of the unmined headwaters of Dogleg were filled with sand tailings, which then released "[c]onsiderable in-bank storage of ground water from this sand[, which] has seeped ever since through Dogleg Preserve and into the replacement stream." Prior to the cessation of mining, though, Dogleg suffered dehydration. According to the CDA, due to the drawdown, the topsoil dried out, and the overburden, on which the topsoil had been placed, hardened in the dry season, retarding root extension. The actual soil conditions are described in greatest detail in the July 1995 semi-annual report, which states that 12 inches of topsoil overlaid the "overburden fill," which was "clayey sand." Repeated and persistent replanting of trees, seedlings, and saplings eventually succeeded in establishing an appropriate wetland forest, which, given the prevalence of hardwoods, would constitute the successful reclamation of a mixed wetland hardwoods community, given the negligible representation of cypress trees and other conifers at the site. As reclaimed, Dogleg hosts 24 different species of wetland trees, including all that occur on OFG. Dogleg's forested wetlands are functioning well, although the reclaimed uplands have a major cogongrass infestation. Permitted in 1985, constructed by 1987, and released in 1998, 19.4-acre FG-84(5) (84(5)) was targeted almost entirely for wetland forested mixed, and small areas within 84(5) have achieved this objective. However, reclamation scientists planted so many cypress trees that their dominance today precludes the application of the wetland forested mixed label to the overall wetland. Nonetheless, 84(5) is a relatively high- functioning forested wetland community today. Engineered to contain hummocks, 84(5) also featured the use of transferred topsoil overlying cast overburden to a depth of at least six feet. Despite the presence of the topsoil layer, the proximity of the cast overburden to the surface, without an intervening sand layer, may have discouraged the formation of an appropriate water table. Although drawing on a lake, 84(5) displayed, in one soil boring during the middle of the wet season, no water table--not even a perched one--through the first 80 inches below grade. A small strip of saturated soil existed at the surface, but the highly compacted and impermeable overburden prevented communication between the wetland and the surficial aquifer. The slopes of 84(5) are also excessively steep. Substantial efforts are required to reclaim the shallow herbaceous wetlands and forested wetlands to be reclaimed at OFG. Deeper marshes and swamps require less effort to reclaim, although they develop more often than targeted when the reclamation scientists overshoot the mark as to hydrology. For shallow wetland systems, which are more important to reclaim, the failures far outnumber the successes, even today, so considerable caution is required in mining high-functioning shallow wetland systems and considerable effort is required in their reclamation. No bay swamps have been reclaimed, except under atypical conditions. Streams The successful reclamation of streams has also proven elusive to reclamation scientists and the phosphate mining industry. Although only one reclamation of a high-functioning, extensive shallow herbaceous wetland exists, fringe and small- scale shallow wetlands have been reclaimed. The difference between the reclamation of shallow herbaceous wetlands and streams is that reclamation scientists have benefited from 25 years of trial and error in engineering shallow wetlands. No similar history exists in the engineering of streams. Only nine stream-reclamation sites are identified in these cases, and, as DEP contends, only one of these sites is successful: Dogleg Branch. And even Dogleg Branch fails to access its floodplain properly and probably never will. The biggest difference between shallow wetlands reclamation and stream reclamation is that, until OFG, the phosphate mining industry has not intensively designed stream-reclamation projects, so IMC and its reclamation scientists have little experience on which to draw. A wetlands-reclamation practice, as found in a Florida Institute of Phosphate Research study described by Mr. Irwin, has been to reclaim wetlands downslope from their pre-mining location. Concentrating reclaimed wetlands downslope facilitates the re-creation of supporting hydrology. For OFG, IMC proposes to relocate wetlands downslope--probably to good effect, given the reversion of OFG to cattle ranching, post- reclamation. However, an adverse aspect of this practice has been the mining of upslope, lower-order tributaries and their replacement with downslope deeper marshes. Although difficult to quantify, this and similar reclamation practices have resulted in the destruction, by phosphate mining, of many lower- order streams and their permanent loss to the watershed and ecosystem. When attempting to reclaim streams, rather than convert them to downslope marshes, the phosphate mining industry and reclamation scientists have enjoyed little success. Two reasons likely explain this poor record: the complexity of the functions of a lower-order stream system, including its riparian wetlands and floodplain, and an excessive reliance on the ability of streams, post-reclamation, to self-organize. The importance inherent in the stream, its riparian wetlands, and its floodplain, as a functional unit, is reflected in the decision of IMC to extend the no-mine area to Horse Creek and its 100-year floodplain. Dr. Durbin accurately observes that IMC and its 100-year floodplain are, respectively, the first and second most important natural resources present at OFG. Horse Creek's tributaries and their floodplains are important for many of the same reasons. Relying upon reclaimed systems to self-organize is an essential element of effective reclamation. Natural and anthropogenic forces shape all of the natural systems present at OFG, and these forces will shape the reclaimed systems. Good reclamation engineering accounts for the dynamic nature of these reclaimed systems by establishing initial conditions, such as natural outfalls instead of weirs and culverts, that can evolve productively in response to the forces to which they are subject and eventually become high functioning, self-sustaining ecosystems. On the continuum between intensively engineered reclamation projects and reclamation projects that rely on self- organization, stream-reclamation projects in the phosphate mining industry have so heavily emphasized the latter approach over the former that they may be said to have reclaimed streams incidentally. That is, reclamation scientists have reclaimed streams by contouring valleys so that the erosive process of flowing water would form a stream channel over time: often, a long time. At DEP's urging after the issuance of the Altman Final Order, IMC has introduced a much more intensively engineered stream-reclamation effort in its Stream Restoration Plan. The main problem in assessing the likelihood of the success of the highly engineered Stream Restoration Plan is its novelty. On the one hand, the incidental reclamation of streams typically has been so slow in restoring functions that a more intensively engineered plan could generate quick gains, at least in the replacement of the functions of low-functioning stream systems, such as those that have been substantially altered by agricultural uses. On the other hand, the Stream Restoration Plan has little success--and no engineered success--on which to build, and misdesigned elements could take longer to correct than the undesigned elements in an incidentally reclaimed stream. Thus, when the uncertainties of successful stream reclamation are combined with the complex functions of lower-order tributaries, their riparian wetlands, and their floodplains, the higher- functioning streams at OFG are less attractive candidates for mining and reclamation than even the shallow wetlands discussed above. Horse Creek's tributaries are not necessarily low- functioning due to their status as intermittently flowing, lower-order streams. Even intermittently flowing, lower-order streams, such as all of the tributaries of Horse Creek, restrict the erosion of sediment into higher-order streams, uptake nutrients, maintain appropriate pH levels, and provide useful habitat for macrobenthic communities, macroinvertebrates, amphibians, and small fish. Intermittently flowing lower-order streams attenuate floodwaters by diverting floodwaters into the streams' floodplains, thus reducing peak flows, extending the duration that floodwater is detained upstream, and increasing groundwater recharge and, thus, streamflow. Intermittently flowing lower-order streams also supply energy for higher-order streams and the organisms associated with these stream systems, as organic material from vegetation, algae, and fungi in the lower-order streams eventually is flushed downstream to serve as food sources to downstream organisms. The functions of streams, including intermittently flowing lower-order streams, become even more complex and difficult to replace when considered in relation to the functions of the riparian forested wetlands associated with many lower-order streams, such as the Stream 1e series. The riparian forested wetlands provide additional attenuation of floodwaters, as the trees impede the flow of floodwater more than would ground-hugging herbaceous vegetation. Mature trees lining the stream provide a canopy that can cool the waters in the warmer months (thus reducing water loss to evaporation), provide downstream food in the form of leaf litter in the seasonal loss of leaves, shield interior water and habitats from the effects of wind, provide habitat for feeding and hiding for wildlife, and protect the channel from the impact of cattle (thus reducing the damage from the production of waste and turbidity and destruction of the channel and vegetation). The riparian forested wetlands are important in the sequestration of nutrients. If accompanied by flow-through wetland systems, such as those present in the Stream 1e series, riparian forested wetlands display a complex interrelationship between the roots and soils that contributes to improved water quality, among other things. The riparian forested wetlands also provide microhabitats whose detail and design would defy the restoration efforts of even the most dedicated of stream- restoration specialists, of whom IMC's stream-restoration scientist, John Kiefer, is one. For some of the stream-restoration projects, DEP explicitly permitted or approved the reclamation of a stream. For other such projects, DEP, at best, implicitly permitted or approved the reclamation of a stream. Four of the projects are tributaries to the South Prong Alafia River and are in close proximity to each other. From upstream to downstream, they are Dogleg Branch, whose forested wetland component has been discussed above; Lizard Branch (IMC-L-SP(10)); Jamerson Junior (IMC-L-CFB(1)); and Hall's Branch (BP-L-SPA(1)). Hall's Branch is about 4-5 miles upstream from the confluence of the South Prong Alafia River and North Prong Alafia River. All four of these reclaimed streams are now part of the Alafia River State Park. As noted above, Dogleg, a 19.8-acre wetland hardwood forest and 83-acre upland hardwood forest, was constructed in 1984 and is the oldest of these four reclamation sites adjoining the South Prong Alafia River. Next oldest is Hall's Branch, which was permitted as a 3.8-acre wetland hardwood forest in 1982, constructed by 1985, and released in 1996. Next oldest is Jamerson Junior, which was permitted as a 4.3-acre wetland forested mixed in 1984, constructed in 1986, and released in 1996. Ten years younger than the others is Lizard Branch, which was permitted in 1983 and modified in 1991, constructed in 1994, and released in 1996; some question exists as to its target community, but it was probably a swamp. The reclaimed stream at Dogleg Branch is part of a second-order stream, although the CDA reports that Dogleg Branch was a first-order stream. Pre-mining, Dogleg Branch and Lizard Branch joined prior to emptying into South Prong Alafia River. Portions of the record suggest that the reclaimed stream lies between unmined stream segments upstream and downstream, although one exhibit, cited below, implies that the mining captured the point at which the stream started. The CDA and the July 1995 semi-annual report state that the headwaters of Dogleg were unmined or preserved. The CDA adds, with more detail than the other sources, that the headwater and first 600 feet of the stream were unmined, and the next 1000 feet, down to the forested riparian corridor of South Prong Alafia River, was mined. Due to its detail, the CDA version is credited, as is the July 1995 semi-annual report: the headwaters of Dogleg Branch are unmined. The July 1995 semi-annual report states that the stream-reclamation component of Dogleg Branch required persistence, as did its forested wetlands component. In 1987, one year after the filling of the mine cuts with sand tailings, as described above, it was necessary to cut a new channel, because the gradient of the old reclaimed channel was too shallow and forced water to back up in the unmined headwaters. Reflective of the age of the reclaimed stream, the understory vegetative species associated with Dogleg Branch are more successional, having replaced the lower-functioning pioneer vegetative species that first predominated after reclamation. As a stream-reclamation project, Dogleg Branch has achieved close to the same success that it has achieved as a reclaimed wetlands forest or that SP(2D) has achieved as an extensive herbaceous shallow water wetland. The slope of Dogleg Branch's reclaimed channel is steeper than the slopes of its unmined channels, and the reclaimed segment, which functions well vertically within the banks of the channel, does not access its floodplain properly, largely due to its entrenched nature. Due to the entrenchment underway, it is unlikely that the reclaimed segment of Dogleg Branch will ever communicate with its floodplain, as its unmined segments do. Entrenchment is a measure of channel incision-- specifically, the width of the floodprone area, at a water level at twice bankfull, divided by the bankfull width. Entrenchment may cause excessive erosion, which may result in adverse downstream conditions, such as turbidity and lost habitat. Proceeding perpendicular to the flow of the water, entrenchment extends the channel into the riparian wetlands or uplands alongside the stream, dewatering any nearby wetlands and disturbing the local hydrology. Especially if entrenchment is associated with head-cutting, which operates up the streambed, the resulting erosion deepens the channel sufficiently that the water in major storm events can no longer enter its floodplain, but rushes instead downstream. Although the failure of Dogleg Branch to access its floodplain would not affect macroinvertebrates, which do not use the floodplains, the failure of the reclaimed stream to access its floodplain harms fish, which cannot access the floodplain during high water levels to forage, spawn, and escape predators or high water volumes, and reduces valuable aquatic-upland ecotones. This failure also reduces the ability of the stream to attenuate floodwaters. By chance, Charlotte County's stream- restoration expert Frederick Koonce visited Dogleg Branch shortly after a June 2003 storm event and saw the water from the stream enter the floodplains adjacent to the unmined segments of Dogleg Branch, but not the reclaimed segment. The less-rigorous approach of incidental stream restoration, at least in the mid-1990s, is evident the summer 1994 semi-annual report on Dogleg Branch, in which Dr. Clewell provides a detailed discussion of the biological aspects of the reclamation of this site. Implying that the incidental stream element of the Dogleg reclamation project may be nine years younger than provided in the parties' stipulation, Dr. Clewell writes: The temporary land use area was abandoned and reclaimed during the autumn of 1993. The perimeter canal was filled and the access road removed between Dogleg marsh and the unmined tip of original Dogleg Branch. Within a few days of a site inspection on December 2, 1993, final grading and revegetation had been completed, and water was discharging from Dogleg marsh into unmined Dogleg Branch for the first time ever. The water was free of turbidity. The entire connection had been sodded with bahiagrass turf. Dogleg Branch enjoys good water quality. On the two days that Charlotte County water quality scientist William Dunson tested its waters, in October 2003 and March 2004, the reclaimed Dogleg Branch had dissolved oxygen of 6.8 and 8.6 mg/l, iron of 325 and 212 ug/l, manganese of 41 and 22 ug/l, and aluminum of 160 and 132 ug/l. The Class III water standard for dissolved oxygen is 5 mg/l, except that daily and seasonal fluctuations above 5 mg/l must be maintained. The Class III water standard for iron is no more than 1.0 mg/l (or 1000 ug/l). There are no Class III water standards for manganese and aluminum. Dogleg Branch also passed chronic toxicity testing for reproductivity and malformation. However, Dogleg Branch is distinguishable from at least one of the OFG streams. Dogleg Branch is a much less complex restoration project because reclamation scientists did not need to re-create headwaters, the first 600 feet of stream downstream of the headwaters, or flow-through wetlands. Also, the mined segment of Dogleg was much shorter than the mined segment of the Stream 1e series: 1000 feet versus 2039 feet for the Stream 1e series. Betraying an emphasis on forested wetlands to the exclusion of streams, Dr. Clewell places Hall's Branch a close second to Dogleg among stream-reclamation projects. However, DEP properly did not add a second stream to its list of successful stream-reclamation projects. Reclaimed Hall's Branch is not close to performing the functions of reclaimed Dogleg Branch, and, because of the large gap between Dogleg and all of the other reclaimed streams, it is irrelevant which of them occupies second place. The most visible shortcoming of the reclaimed stream at Hall's Branch is its color. Parts of the water in the reclaimed stream within Hall's Branch are highly discolored with iron flocculent leaching from the surrounding mesic forest and shrub communities. Mr. Dunson's water quality tests in reclaimed Hall's Branch, in October 2003 and March 2004, revealed iron levels of 117,000 ug/l and 4025 ug/l, which are 117 times and 4 times the Class III water standard. Dissolved oxygen was also well below Class III standards at 1.5 mg/l and 2.1 mg/l. Manganese was 1880 ug/l and 392 ug/l, and aluminum was 226 ug/l and 35 ug/l. Like Dogleg Branch, Hall's Branch also passed chronic toxicity tests for reproductivity and malformation. The hydrological connection between the surficial aquifer and the reclaimed stream at Hall's Branch is probably interrupted. Mr. Carter, who did not visit Dogleg Branch, inspected Hall's Branch and found the water table 12 inches below the surface. A soil sample reveals overburden with a layer of topsoil. The CDA seems to indicate that part of Hall's Branch was backfilled with sand tailings of an unspecified depth and part of it was merely contoured overburden--a pattern suggestive of that planned for OFG. The CDA states that trees were planted in mulched areas. The reclaimed forest is dominated by cypress, not the targeted wetland hardwoods. Jamerson Junior is a 4.3-acre reclamation site permitted as a wetland forested mixed community in 1984, constructed by late 1985, and released in early 1996. Part of the reclaimed stream is a second-order stream. Like Hall's Branch, Jamerson Junior also shows signs of orange-colored water leaching in to the stream from the nearby mesic zone. However, the water quality in Jamerson Junior is closer to the water quality in Dogleg Branch than Hall's Branch. Mr. Dunson's iron readings, in October 2003 and March 2004, were 583 ug/l and 195 ug/l, which are within Class III standards. Dissolved oxygen was slightly higher than at Dogleg Branch: 7.0 mg/l and 8.0 mg/l. Manganese was 136 ug/l and 21 ug/l, and aluminum was 391 ug/l and 101 ug/l. However, Jamerson Junior failed chronic toxicity testing for reproductivity, but passed for malformation. This is the only stream that IMC also tested for toxicity, and IMC obtained similar results, according to Dr. Durbin. Soil samples reveal a highly variable soil structure underlying Jamerson Junior. Subsequent reclamation work on the stream required the addition of material to change the elevation of the stream bed and possibly to change the drainage characteristics of the original backfilled material. On the day that Mr. Carter visited Jamerson Junior on August 14, 2003, he found the stream flowing. During the wet season, the water table should normally be expressed in the stream. Presenting a more interrupted relationship between the surficial aquifer and the stream than at Hall's Branch, Jamerson Junior displays no connection between the stream bed and water table, at least to a depth of 40 inches. A soil boring revealed water immediately underneath the stream bed, but, at about 15 inches beneath the bottom of the bed, the soil dried to moist; at 40 inches, Mr. Carter found the water table under the stream. Likewise, the Jamerson Junior channel was poorly integrated with the surrounding wetlands and uplands. At the banks of the stream, Mr. Carter did not find the water table within 80 inches of the surface, which is additional evidence of a discontinuity between the water table and the stream. Much of the reclaimed forested areas are mesic, not hydric. The reclaimed floodplains are narrower than the floodplains in the unmined adjacent area, and the slope of the reclaimed channel is steeper than the slope of the unmined channel. The reclaimed uplands are infested with cogongrass, although less than is present at Dogleg. Lizard Branch is a 6-acre reclamation site permitted as a swamp community in 1983 and modified in 1991, constructed by 1994, and released in 1996. Few of the planted gums and maples are surviving. The uplands surrounding the reclaimed area are infested with cogongrass, which has penetrated the shallower wetlands. Lizard Branch is one of the lowest- functioning forested wetlands. Lizard Branch joins Jamerson Junior as one of only two of six reclaimed stream sites to fail chronic toxicity testing for reproduction, although it passed for malformation. Lizard Branch had the highest two dissolved oxygen readings of all six sites tested by Mr. Dunson: 12.6 mg/l and 7.1 mg/l. Its iron levels were 547 ug/l and 352 ug/l. Manganese was second lowest, behind only Dogleg Branch, at 71 ug/l and 30 ug/l. Aluminum was second highest at 445 ug/l and 45 ug/l. Lizard Branch is an interesting, recent reclamation site for several reasons. Lizard Branch represents a relatively recent instance of the destruction of a stream without its re- creation and either the failure of the incidental reclamation of a stream or the subsequent permission by DEP to allow the permanent elimination of the stream. Mr. Winchester testified that he could not even find a stream at Lizard Branch. Charlotte County ichthyologist Thomas Fraser treated Lizard Branch as a stream, but grouped it with marshes in his analysis, apparently due to the lack of channel formation. The fact is that, despite any effort to reclaim a stream, little, if any, stream structure is present at Lizard Branch. However, a stream once flowed over the reclaimed portion of Lizard Branch. In the summer 1994 semi-annual report, Dr. Clewell notes that Brewster Phosphate received a dredge and fill permit in 1983 to dredge and fill the "headwaters of two streams, Dogleg Branch and Lizard Branch" in connection with the mining at Lonesome Mine. Dr. Clewell adds: The permit was issued with the stipulation that the streams and their attendant riverine forest would be restored on adjacent physically reclaimed lands, concomitant with mining. The permit further stipulated that restoration would be monitored and that semi-annual reports documenting progress in vegetational restoration would be submitted to [DEP.] In the report, Dr. Clewell notes that reporting on Lizard Branch has been "discontinued" and DEP issued a new permit in 1991. The 1991 permit modification is not part of this record, but the result was the elimination of a stream, or at least any signs of a stream ten years after construction. Three of the remaining reclaimed-stream projects were built at about the same time as Lizard Branch project. For only one of these projects did the reclamation scientists explicitly target a stream. Permitted in 1985 and subject to a consent order in 1996, constructed in 1991-92 and 1995, and not yet released, 9.6-acre Tadpole Wetland (H-SPA(1)) was targeted to be about one-third wetland forested mix and two-thirds freshwater marsh. Much cogongrass has infested Tadpole, whose stream enters the Alafia River floodplain and leads to a ditch that runs the remainder of the distance to a point close to the Alafia River. Tadpole's water passed chronic toxicity testing for reproductivity and malformation. However, its water violated Class III standards for dissolved oxygen, with readings of 2.8 mg/l and 2.1 mg/l, and for iron, with readings of 11,300 ug/l and 1100 ug/l. Manganese levels were 166 ug/l and 20 ug/l, and aluminum levels were 660 ug/l--the single highest reading among the four reclaimed streams tested--and 95 ug/l. Permitted in 1985, constructed by 1996, and not yet released, Pickle Wetland (H-SPA(1)) is a 34-acre site, 0.8 acres of which was to be reclaimed as stream. A deep marsh that requires treatment of its nuisance exotics, such as cattails and primrose willow, Pickle is just northeast of Tadpole and a few miles north of Morrow Swamp and Ag East. Pickle's stream is surrounded by uplands. Pickle is the only reclaimed stream of six tested to fail chronic toxicity testing for malformation, although it passed for reproductivity. Pickle has the lowest dissolved oxygen of the six reclaimed streams tested by Mr. Dunson: 0.8 mg/l and 1.2 mg/l. Its iron levels violated Class III standards in October 2003, with a level of 4230 ug/l, but passed in March 2004, with a level of 786 ug/l. Manganese was 127 ug/l and 72 ug/l, and aluminum was 107 ug/l and less than 5 ug/l. Permitted in 1991, constructed in 1995, and not yet released, Trib A ((BF-ASP(2A)) is a 120-acre site to be reclaimed as a wetland forested mix, but it includes a slough that empties into an unmined channel with streamflow. To the extent that a reclaimed stream channel is discernible on Trib A, nine years after the completion of its reclamation, the channel is much more steeply sloped than the adjacent unmined channel-- steeper than the two percent slope, beyond which sandy stream bottoms begin to erode. Not surprisingly, the reclaimed channel has begun to head cut and entrench. In an adjacent unmined area, a stream exists within a floodplain with a very flat slope. In the mined area, the reclaimed floodplain is steeper, suggestive of impeded communication between the reclaimed stream and its floodplain. The groundwater communication at Trib A is almost as interrupted as it was at Jamerson Junior. At Trib A, the uppermost 20 inches of soil was saturated, at the time of Mr. Carter's site inspection. Beneath a moist soil layer, the water table occurred at 40-50 inches deep. Parts of Trib A were topsoiled, but the next layer down was originally from an area below the C horizon. However, the soil-formation process is underway. Permitted in 1995, constructed by 1998, and not yet released, 17.6-acre File 20-2B and 70-3 Dinosaur Wetland (FG- GSB(7)) was reclaimed as a freshwater marsh. Dinosaur is due south of Morrow Swamp and is a headwater wetland. The site is still undergoing treatment for cattails. The record describes little, if anything, about the status of this stream. The last two stream-reclamation reclamations were built at least five years after the last pair. Again, DEP and the phosphate mining company identified a stream as a target for only one of the projects. Permitted in 1989, 1992, and 1998, constructed in 1999, and not yet released, South Bradley (KC-HP(1A) is a 171- acre site, 1.7 acres of which was to be reclaimed as stream. South Bradley is just north of Pickle. The channel is steeply incised and deep at points. The channel runs through forested and unforested areas. Charlotte County ichthyologist Thomas Fraser found iron flocculent in South Bradley and no fish within this area of the reclaimed stream, but three species of fish in a nearby area. Permitted in 1999, constructed by 2003, and not yet released, MU R Wetland H (KC-HB(1)) is a 4.8-acre site to be reclaimed as wetland hardwood forest. Monitoring has not yet begun for this site. Although a tailwater system receiving water from a ditch running to a lake, rather than a natural stream, the channel that has formed in MU R Wetland H does not join the existing downstream channel; the two channels are offset by 75-100 feet. Also, the reclaimed floodplain of MU R Wetland H is more steeply sloped than the floodplain of the adjacent unmined area. The slope of the reclaimed channel is steeper than the slope of the unmined channel, and, due to poor design parameters, the new channel is headcutting into the floodplain, which does not appear to be communicating appropriately with the stream. Combining a more steeply sloped reclaimed floodplain with a headcutting reclaimed stream means, among other things, substantially less communication between the stream and its floodplain. The hydrology of MU Wetland H appears to have been ineffectively reclaimed. In the forested wetland a short distance from the stream, the soil remained unsaturated until 80 inches deep. Closer to the stream, the soil was saturated at a depth of 18-20 inches, but the underlying overburden remained dry to a depth of 70 inches, indicating again a failure to reclaim the water table at appropriate depths. As with all of the almost countless reclamation sites on which the parties' expert witnesses copiously opined, MU R Wetland H is not well-developed in the record in terms of pre- mining conditions, design elements, construction techniques, and post-reclamation conditions. However, the dislocated stream that has formed within this reclaimed wetland stream reinforces the principle that even incidental stream reclamation requires some engineering. The excessive reliance upon a contoured valley to self-organize into a stream, as noted above, has impeded the progress of the science of stream restoration, as applied to mined land in Florida. This factor is unique to streams and does not apply to uplands and wetlands. However, another factor has impeded progress in reclaiming successful systems--whether uplands, wetlands, or streams. This factor is undue emphasis on the identity of post-reclamation vegetation, as compared to pre- mining or reference vegetation, at the expense of function. Charlotte County and the Authority stressed the process of the identification of vegetative species, at the expense of undertaking complex functional analysis and attempting to situate reclaimed systems in the process of energy consumption and production. In part, their cases relied on showing that past reclamation projects, as well as that proposed for OFG, do not replicate pre-mining or reference-site vegetation. An undue emphasis on species identity suffers from two major flaws. First, as Dr. Clewell and Ms. Keenan testified, reclaimed sites undergo stages of colonization, and, during early stages, less-desirable species, such as Carolina willow and wax myrtle, may predominate at more-desirable canopy-forming species succeed them. Ms. Keenan added that the life expectancy of Carolina willow, in this part of Florida, is about 25 years, and no reclaimed site older than 15 years is dominated by Carolina willow. Second, any measure of species identity risks the elevation of replication over function, as DEP has already recognized. A criterion of replication, for example, discredits a reclaimed site with a lower species-identity score because it has been colonized by a greater share of more-desirable species than occupy the reference site. DEP has wisely discontinued the practice of assessing reclamation success in partial reliance upon the Morisita's Index. This index measures the identity of species between two sites or the same site pre-mining and post-reclamation, as a criterion of successful wetlands reclamation. In a similar vein, DEP has recently recognized that vegetative analysis cannot preemption functional analysis, especially as to streams. This recognition is evidenced by a report entitled, "Riparian Wetland Mitigation: Development of Assessment Methods, Success Criteria and Mitigation Guidelines," which was managed by Ms. Keenan, revised May 10, 2001, and filed with the U.S. Environmental Protection Agency Grants Management Office (Riparian Wetland Mitigation). Riparian Wetland Mitigation notes the unsatisfactory history of stream reclamation projects with their emphasis on vegetation to the exclusion of stream hydrology and geomorphology. Riparian Wetland Mitigation states: The more recent methods [of stream restoration] recognize that streams are not simply water conveyance structures, but are complex systems dependent on a variety of hydrological, morphological, and biological characteristics. It is now recognized that in order to successfully restore or create a stream, hydrology, geology and morphology must be considered in the design. Noting the increasing extent to which the phosphate mining industry is applying for permits to mine more and larger stream systems and reclaim them on mined land, Riparian Wetland Mitigation frankly admits: The success criteria included in permits issued by the Department for these newly created streams have been based primarily on vegetational characteristics as is typical of most permits requiring wetland mitigation. However, vegetation alone is a poor indicator of stream function and community health. The results of regular permit compliance inspections of existing stream mitigation projects . . . have suggested that for several projects, although existing riparian vegetation was meeting or trending toward meeting permit requirements, problems existed with site hydrology and habitat quality of the stream channel itself. DEP thus adopted a rapid bioassessment method known as BioRecon, which tests macroinvertebrates, and added two other components: habitat assessment and physical/chemical characterization. DEP then performed "BioRecon, habitat assessment, and physical/chemical sampling" on eight reclaimed streams. Of the eight sites sampled, "only one passed the BioRecon and Habitat Assessment." (It is unclear whether Riparian Wetland Mitigation intends to imply that this site-- obviously, Dogleg Branch--also passed the physical/chemical composition, but it probably did.) DEP then tested smaller, unmined streams and confirmed that they, too, could pass BioRecon and Habitat Assessment. Riparian Wetland Mitigation states that DEP will collect data from comparable unmined streams and attempt to relate geomorphological, hydrological, and biological data to develop more refined criteria by which to assess proposed stream-reclamation projects. When DEP issues these criteria, the likelihood of success of a specific stream-reclamation project will be easier to assess. Until then, the assessment of a specific stream-reclamation project remains more difficult, in the context of past reclamation projects that have reduced or even eliminated important functions of streams. Although DEP's new guidelines for stream restoration will mark a transition from a predominantly vegetative to a multi-variable analysis of stream function, even a predominantly vegetative analysis of stream function is superior to IMC's analysis of streams predominantly from the perspective of flood control, as set forth in the CDA prior to the Altman Final Order. In a remarkably candid admission of the difficulty of reclaiming the many functions of unaltered stream systems, including their riparian wetlands and floodplains, IMC, in its response to RAI-102 in the CDA, states: Although it is impossible in a reasonable amount of time to expect to restore the functionality of the creek systems and associated uplands which historically occurred on the One site and are proposed for mining, it is reasonable to conclude that the reclamation plan restores the primary functions of the watershed[:] i.e. the capture, storage, distribution, and release of precipitation. IMC's subsequent discussion in RAI-102 emphasizes the efficacy of mitigation, from a biological perspective, but only as to stream systems whose pre-mining condition is substantially altered. For relatively unaltered systems, IMC's message remains that the reclamation of functions, besides water quantity, within a reasonable period of time is "impossible." Summary of Findings on Past Mitigation/Reclamation Any attempt at assessing past reclamation projects is impeded by the general lack of data presently available, for each reclamation site, describing pre-mining hydrological, topographical, soil, and geological conditions; the functions of pre-mining communities; reclamation techniques; post-reclamation hydrological, topographical, soil, and geological conditions; and the functions, as they have evolved over time, of reclaimed communities. For post-reclamation water tables, the auger and shovel work of one or two men substitutes for several years of weekly piezometer readings in the wet season and monthly piezometer readings in the dry season--correlated to daily rainfall data collected at the same site. For post-reclamation water quality, a few preliminary toxicity and a few dozen water quality readings--some under less than optimal conditions-- substitute for systematic water-quality testing of a broad range of parameters, again over years. For post-reclamation soils, one soil scientists finds an A horizon and concludes substantial formation has taken place within 10 years; another finds an A horizon--never the same one at the same place--and concludes topsoil transfer; and both are probably correct. Absent better data, reliable analysis is difficult because a wide variety of factors may have contributed to the successes of SP(2D) and Dogleg and the failures of too many other sites to list. Even so, a few facts emerge. IMC can reclaim extensive areas of uplands, deep marshes, and cypress swamps, although difficulties remain with each of these types of reclamation projects. With greater difficulty, IMC can reclaim pine flatwoods and palmetto prairies. With even greater difficulty, IMC can also reclaim forested wetlands, except bay swamps. Far more difficult to reclaim than the communities mentioned in the preceding paragraph are extensive shallow wetlands, seepage bayheads, and streams. Any finding of present ability to reclaim these systems must uneasily account for the numerous failures littering the landscape, the failure ever to reclaim successfully a bayhead as bay swamps typically occur in the landscape, and the unsettling fact that nearly all reclamation successes of shallow wetlands are small patches-- almost always far smaller than designed. Any finding of present ability to reclaim these systems must rely heavily on SP(2D) and Dogleg Branch and the design of the current reclamation plan. The probability of the successful reclamation of any community, but especially extensive shallow wetlands, seepage bayheads, and streams, requires careful analysis of each community proposed to be mined and each community proposed to be reclaimed. For each such community, it is necessary to assess its ultimate functions of consuming and producing energy within a robust, sustainable ecosystem. Additional Features of OFG, Mining, and Reclamation Introduction The preceding sections detail the ERP, CRP approval, and WRP modification and other mitigation sites involving the reclamation of uplands, wetlands, and streams. This section adds information concerning OFG in its pre-mining condition, the proposed mining operations, and the proposed reclamation. OFG IMC adequately mapped the vegetative communities at OFG. As Doreen Donovan, IMC's wetlands biologist testified, trained persons using the FLUCFCS system of classifying vegetative communities tend to fall into one of two categories: lumpers or splitters. Scale dictates FLUCFCS code in many cases. Where one biologist may designate a larger, more varied area with one code, another biologist may designate the same area with several codes. The purpose of FLUCFCS coding dictates the scale. Subordinating vegetative-identity analysis to functional analysis undermines the arguments of Charlotte County and the Authority for an unrealistic level of precision in this exercise. The discrepancies in vegetative mapping noted by Mr. Erwin were insignificant. Many were the product of scaling differences, as noted in the preceding paragraph. Some were the product of distinctions without much, or any, difference, given the context and extent of the proposed activities. For present purposes, absent demonstrated differences in wildlife utilization, groundwater movement, or soil, distinctions between, for example, xeric oak and sand live oak on ten acres are essentially irrelevant. In total area, as compared to the 4197 acres of OFG, the claimed discrepancies did not rise to the level of noteworthy. As for the wetlands at OFG, DEP's acknowledged expert in wetlands identification, Deputy Director Cantrell, personally visited OFG and confirmed the accuracy of the wetlands determinations made three years earlier in December 2000 when DEP issued a Binding Wetland Jurisdictional Determination, which remains valid through December 2005. Deputy Director Cantrell noted minor omissions that might total a couple of acres, but these are insignificant, again given the scale of the proposed activity. The sole material flaw in IMC's mapping of OFG is in the omission of floodplains of the tributaries from Map C-3, although Dr. Garlanger's hydrological analysis, described below, adequately considered the storage and conveyance characteristics of these floodplains. Proper analysis of the tributaries' functions, besides flood control, and proposals to reclaim them is impeded by IMC's failure to depict graphically the 2.3-, 25-, and 100-year floodplains. The record suggests that BMR may have waived any requirement for maps of the floodplains except for those of Horse Creek, but the record does not suggest that, if BMR actually waived this requirement, it thus insulated the CDA from scrutiny with respect to all the information that would have been contained in floodplain maps or assured IMC of favorable analysis of this missing information. Charlotte County hydrologist John Loper prepared floodplain maps, which are Charlotte County Exhibits 1762 (mean annual floodplain), 1763 (25-year floodplain), and 1764 (100- year floodplain). These are credited as accurate depictions of the floodplains of the tributaries of Horse Creek. Mr. Loper's maps reveal little difference between the 25- and 100-year floodplains over much of OFG, including the Panhandle. The two floodplains of Stream 3e are slightly different, but the two floodplains of the Stream 1e series are less noticeably different. Focusing on the 25-year floodplain, the only wide, lengthy floodplain outside of the no-mine area is the floodplain along the Stream 1e series, which is the widest band of floodplain outside the no-mine area. At places, the floodplain of the Stream 1e series is as wide as the corresponding floodplain of Horse Creek. Even at its narrowest, which is along Stream 1ee, the floodplain of the Stream 1e series is as wide as that of Stream 2e and wider than that of Stream 3e. No 25-year floodplain runs along ditched Stream 3e?. The only other portions of the 25-year floodplain contiguous to the floodplain of Horse Creek, but outside the no-mine area, are the large wet prairie at the head of Stream 9w, the large wet prairie at the head of Stream 5w, and the headwater wetlands of Streams 1w-4w. As already noted and discussed in more detail below, all of these wetland systems, including the headwaters of Streams 1w and 3e, are lower-functioning than the wetland system associated with the Stream 1e series. As noted above, over half of the area to be mined is agricultural and another quarter of the area to be mined is uplands consisting largely of sand live oak, pine flatwoods, and palmetto prairie. Accordingly, OFG is characterized by native flatwoods soils, which exhibit high infiltration rates, but restricted percolation due to underlying hardpan or loamy horizons. About one-fifth of the soils at OFG are xeric soils. The wet season water table in the wetter areas will be 0-2 feet below grade and in the uplands over 3 feet below grade. Nothing in the record suggests that IMC will have much difficulty in reclaiming agricultural land or sand live oak communities. Nothing in the record suggests that any of the sand live oak that will be mined is atypically valuable habitat. As noted above, the pine flatwoods and palmetto prairie are more difficult to reclaim, but the pine flatwoods and palmetto prairie at OFG are not atypical instances of these common upland habitats. Some of these communities have been stressed by the lack of fire, so that hardwoods, such as oaks, have become sufficiently established as to resist thinning by fire. Lack of fire has also resulted in overgrown vegetation in more xeric areas. Among forested wetlands, IMC will mine 43 acres of mixed wetland hardwoods, 12 acres of hydric pine flatwoods, 9 acres of bay swamps, and 6 acres of hydric oak forests. Among herbaceous wetlands, IMC will mine 95 acres of wet prairie and 67 acres of freshwater marsh. Map F-3 depicts these wetlands with color-coding for ranges of wetlands values, under the Wetland Rapid Assessment Procedure (WRAP), which is used by the U.S. Army Corps of Engineers. Following a weeklong investigation of wetlands at the Ona Mine, as well as other IMC mines in the vicinity, the U.S. Army Corps of Engineers expressly approved revisions to WRAP to accommodate local conditions at OFG. DEP used a different assessment procedure, but WRAP remains useful for general indications of wetlands function. The WRAP scoring scale runs from 0-1, with 1.0 a perfect score. For ease of reading, the following sections shall identify wetlands scoring below 0.31 as very low functioning, wetlands scoring from 0.31 to 0.5 as low functioning, wetlands scoring from 0.51 to 0.7 as moderate functioning, wetlands scoring from 0.71-0.8 as high functioning, wetlands scoring from 0.81-0.9 as very high functioning, and wetlands scoring from 0.91-1.0 as the highest functioning. The asymmetry of the labeling scheme is to allow differentiation among the wetlands in the highest three categories, which, at OFG, are disproportionately represented, as compared to the lowest three categories. The purpose of these descriptors is only to differentiate relative values. As already discussed, the Map F-2 series identifies existing wetlands alphanumerically and by community, and Map I-2 similarly identifies all post-reclamation communities. In contrast to all reclaimed wetlands, which, as already noted, start with an "E" or "W," all existing wetlands start with a "G" or "H." The ease with which freshwater marshes are reclaimed obviates the necessity of extensively analyzing the condition of marshes presently at OFG, absent evidence of atypical habitat value. In general, the wetland corridor of Horse Creek, as defined by the no-mine area, ranges in quality from very high functioning in Section 29, which is the southernmost end of Horse Creek in OFG, to high functioning north of Section 29. However, narrow fringes of this corridor north of Section 29 are low functioning. Starting from the south, in Section 29, three wetlands are outside of the no-mine area: H031/H032/H033/H034, the G005 wetland complex, and a fringe of the wetlands running adjacent to Horse Creek--the western edges of G262, G266, and G259A are outside of the no-mine area. H031 is the largest part of the H031 complex and is mixed wetland hardwoods. H032 is a small freshwater marsh, and H033 is a hydric oak forest of the same size. H034 is a slightly larger wet prairie. H033 is low functioning. The remainder are high functioning. IMC will reclaim the same communities, as an ephemeral wetland complex. Pre-mining and post-reclamation, this wetland drains into West Fork Horse Creek. Considerably larger than H031, the G505 wetland complex is the headwater wetland of Stream 1w. G512 is the largest component of the G505 wetland complex and is wetland forested mixed. G513 is the next largest component and is a bay swamp. G514 is a fringe wet prairie. Slightly larger than G514, G511 is hydric oak forest. G507 is mixed wetland hardwoods, G506 is a small freshwater marsh, and G505 is a cattle pond. The mixed wetland hardwoods and fringe wet prairie are very high functioning, the bay swamp is high functioning, and the remaining wetlands are moderate functioning. IMC will reclaim the G505 wetland complex as a single bay swamp. G262 and G266 are wet prairie and hydric rangeland, respectively. G259A is mixed wetland hardwoods. The wet prairie and hydric rangeland are moderate functioning, and the mixed wetland hardwoods is very high functioning. IMC will reclaim these wetlands as wet prairie. Section 20 contains the headwater wetlands of Streams 2w, 3w, 4w, and 5w. These are mostly marshes, and they are all low to moderate functioning. These systems have been heavily impacted by agricultural uses. IMC will reclaim these as headwater systems, mostly marshes. IMC will also create one small and one medium ephemeral wet prairie near the headwater wetland of Stream 4w. Section 19, which drains to West Fork Horse Creek, contains three wet prairies (H002, H005, and H006) and a complex consisting of a bayhead (H009A) surrounded by a mixed wetland hardwoods (H009), which is fringed by a small wet prairie (H008). These wetlands are all low to moderate functioning. IMC will reclaim the H008 complex with a bay swamp buffered by a temperate hardwood, and it will restore a cattle pond at the site of the H002 complex. The reclaimed bay swamp will drain to West Fork Horse Creek. Section 18 contains a very low functioning, small wet prairie (H056), which is the only wetland in one of the three lowest ranges of WRAP scores outside of the wetland corridor of Horse Creek. Section 18 also contains a small part of a large wetland that is mostly in Section 17. The latter wetland is addressed in the discussion of wetlands in Section 17. Section 17 contains the West and Central Lobes. The entire Central Lobe is in the no-mine area, but a large wet prairie (G188) abuts the wetlands in the no-mine area of the West Lobe. IMC will reclaim this wet prairie, which is low functioning, as improved pasture, with a strip of hardwood conifer mixed. Several wetlands unassociated with the West and Central Lobes are outside the no-mine area, but on either side of Stream 6w, which leads to the West Lobe. G183, which is the headwater wetland of Stream 7w, is a freshwater marsh, which is moderate functioning. IMC will not reclaim the existing portion of Stream 7w upstream of the no-mine area, so the connected headwater marsh will be reclaimed as an ephemeral wet prairie. South of Stream 7w is a group of four small wetlands: G089, G090, G091/G092, and G093/G094. G089 and G090 are very small wet prairies. G091 and G093 are freshwater marshes, and G092 and G094 are wet prairie fringes. G090 is low functioning, and G089 and G091 are moderate functioning. G093 is very high functioning, and G094 is high functioning. Even the maps on the February submittal CD are unclear, but it appears that G089 and G090 will be reclaimed as ephemeral wet prairies. IMC will reclaim G091 as a small freshwater marsh fringed by a large mixed wetland hardwood and G093 as a large freshwater marsh fringed on the east by a small mixed wetland hardwood. The last version of Figure 13B-8 depicts the small freshwater marsh as isolated, but the large freshwater marsh as ephemeral. IMC will also create two small ephemeral wet prairies due south of the West Lobe and one small ephemeral wet prairie just east of the north end of the West Lobe. About one mile west of Horse Creek is a large wet prairie surrounding a smaller freshwater marsh that has been ditched for agricultural purposes. Part of this wet prairie extends into Section 18. The portion of this system in Section 18 is low functioning; the rest of it is moderate functioning. IMC will reclaim this entire area as improved pasture, except for replacing a single cattle pond. Section 16 spans Horse Creek, but mostly covers an area east of the stream, including the East Lobe. The only wetland outside the no-mine area on the west side of Horse Creek is G076/G077, a freshwater marsh fringed by a wet prairie. This small wetland is moderate functioning, and IMC will reclaim it as an ephemeral wet prairie. East of Horse Creek lies Stream 5e and its flow- through wetland, G204/G205. Predominantly a wet prairie, G204 is low functioning. IMC will reclaim it as a bay swamp. A small fringe wet prairie (G177) lies at the south end of the East Lobe, outside of the no-mine area, but it is low functioning, and IMC will reclaim it as hardwood-conifer mixed. A mixed wetland hardwood (G096), which is moderate functioning, fringed by a wet prairie (G097), which is low functioning, lie just north of where the no-mine area of the East Lobe joins the main no-mine area along Horse Creek. IMC will reclaim this wetland as a freshwater marsh fringed on the east by a wet prairie, and this wetland will be connected to the wetlands of the Horse Creek corridor. A freshwater marsh (G058) lies outside the no-mine area just north of the northeast tip of the East Lobe. This wetland is moderate functioning. IMC will reclaim this site as improved pasture, but will create a small ephemeral wet prairie just to the west of G058 and a larger freshwater marsh to the west of the created wet prairie. Section 8 contains two large areas of wet prairie (G048 and G047) at the head of Stream 9w. These wet prairies are moderate functioning, as are a couple of small wet prairies in Section 8 at the western boundary of OFG. IMC will reclaim these areas mostly as improved pasture, although it will create a large, connected wet prairie over the southeastern part of G048, but extending farther to the south and east. This reclaimed wet prairie will form the headwater wetland of reclaimed Stream 9w, which, as already mentioned, will be shortened from its current length. The only other wetland in Section 8 and outside the no-mine area is a freshwater marsh (G052). This marsh is high functioning. IMC will reclaim this site with a marsh and wet prairie. Like Section 16, Section 9 spans both sides of Horse Creek. On the west side of Horse Creek is mixed wetland hardwoods (G055) fringed by hydric woodland pasture (G054). The mixed wetland hardwoods is high functioning, and the hydric woodland pasture is moderate functioning. IMC will reclaim this site with a gum swamp fringed by temperate hardwoods upland. On the east side of Horse Creek, a small wet prairie (G167) is outside the no-mine area. This very high functioning wet prairie is connected to a large bay swamp (G166) to the north. The bay swamp, which is high functioning, lies partly within and partly outside the no-mine area and is connected to the wetland corridor of Horse Creek. Although high functioning, G166 is overdrained by a tile drain system that drains the citrus grove immediately upland and east of G166. Two mixed wetland hardwoods, which are outside the no-mine area, fringe the bay swamp; they are high functioning. IMC will reclaim a gum swamp for the wet prairie and all mixed wetland hardwoods for the east side of the bay swamp. Just north of the bay swamp that straddles the no- mine boundary is a much smaller bay swamp (G163) fringed by mixed wetland hardwoods (G164) that also straddle the no-mine boundary. Also connected to the wetland corridor of Horse Creek, these wetlands are very high functioning, and IMC will reclaim them with pine flatwoods. Between these two bay swamps straddling the no-mine boundary and the headwater wetland of Stream 8e is a small wet prairie (G041), which is moderate functioning and outside the no-mine area. IMC will reclaim this site with another ephemeral wet prairie. At the southern tip of the headwater wetland of Stream 8e is hydric flatwoods (G157), which is moderate functioning. IMC will reclaim this connected wetland with sand pine flatwoods. A smaller hydric woodland pasture (G154) also connects to another section of hydric flatwoods, which is in the no-mine area between the headwater wetlands of Streams 8e and 7e. The hydric woodland pasture is moderate functioning, and IMC will replace it with hardwood-conifer mixed, although IMC will reclaim a somewhat larger area of mixed wetland hardwoods just north of the present site of the hydric woodland pasture, where no wetland presently exists. The remaining wetlands outside the no-mine area in Section 9 are six isolated wet prairies. They are small wetlands, except for G039/G040, which is a wet prairie fringing a cattle pond, and G039, which is at the eastern boundary of OFG. However, they are all high functioning, even the wet prairie fringing the cattle pond. In this general area, IMC reclaims three ephemeral wet prairies, much closer to the no- mine area than the sites of the six isolated wet prairies, and a small freshwater marsh fringed by a community that is not listed in the legend in Map I-2. Interestingly, IMC also reclaims a large area of shrub and brushland and larger area of sand live oak, again closer to the no-mine area than the sites of some of the six isolated wet prairies. The remainder of the area will be reclaimed as improved pasture. Section 4 contains no-mine area in its southeast corner: Stream 2e and the Heart-Shaped Wetland. Almost all of the wetlands outside the no-mine area in Section 4 are in the top three scoring categories of functioning. Of the six wetlands complexes on OFG that are, in whole or in part, highest functioning, four of them are in Section 4. The two highest functioning wetlands outside Section 4 are in the no-mine area, and one of the highest functioning wetlands in Section 4 is in the Heart-Shaped Wetland. Three of the highest functioning wetlands are thus to be mined. Outside of Section 4, there are 14 wetlands or wetlands complexes outside the no-mine area that are in the second- and third-highest scoring categories. These are the mixed wetland hardwoods (H031) in Section 29; a small piece of mixed wetland hardwoods (G259A) straddling the no-mine boundary in Section 29; the bay swamp and mixed wetland hardwoods to the north in the headwater wetland of Stream 1w, which straddles Sections 29 and 20; the freshwater marsh partly fringed by wet prairie (G093) south of Stream 6w in Section 17; the freshwater marsh (G052) connected to Stream 9w and straddling Sections 17 and 8; the mixed wetland hardwoods flow-through wetland (G055) in Stream 9w and straddling Sections 8 and 9; the two bisected bay swamps (G166 and G163) and their mixed wetland hardwoods fringes in Section 9; and the six isolated wet prairies in the northeast corner of Section 9. In Section 4, there are only nine wetlands or wetlands complexes outside the no-mine area that are not in the second- or third-highest scoring categories, and all but two of them--a very small wet prairie fringe (G006) and half of a larger hydric woodland pasture (G105)--are at least moderate functioning. The wetlands in Section 4 fall into three categories: connected to the Stream 1e series, connected to Streams 3e and 3e?, and isolated. The long connected wetland of Stream 1e is mixed wetland hardwoods (G110). This wetland is high functioning, except for the headwater wetland of Stream 1ef, which is highest functioning. A narrow strip of wetland forested mixed (G132) runs along Stream 1ee. This wetland is moderate functioning. Proceeding from south to north, upstream the Stream 1e series, a freshwater marsh (G129) immediately upstream of Stream 1ee is high functioning, as is a smaller freshwater marsh (G125) immediately upstream of Stream 1ed. Two gum swamps (G123 and G121) in the flow-through wetland at the head of Stream 1ed are very high functioning, as is a freshwater marsh (G126) in the same wetland complex. Just downstream of Stream 1ef is a small freshwater marsh (G115) that is high functioning. Part of the mixed wetland hardwoods abutting this marsh to the east is very high functioning. Just upstream of Stream 1eb is the largest wetland complex of the Stream 1e series wetlands system. The largest communities forming this complex are hydric flatwoods (G107) and mixed wetland hardwoods (G110). The mixed wetland hardwoods envelope a small freshwater marsh (G108) and are fringed on the north by a strip of wetland forested mixed (G102). At the northernmost end of this complex is hydric woodland pasture. All of these communities are high functioning except the hydric woodland pasture, which is moderate functioning, and the hydric flatwoods and half of the marsh, which are very high functioning. Working back downstream, IMC will reclaim the mixed wetland hardwoods of the stream corridor, neglecting to replace the complexity provided by the three of the four flow-through marshes (G108, G125, and G129), the larger headwater marsh (G126), and the two gum swamps. IMC will also neglect to replace even the wetland function of the large hydric flatwoods (G107) and smaller hydric woodland pasture, as these sites are reclaimed as upland communities: pine flatwoods and temperate hardwoods, respectively. However, IMC will add complexity by adding a small marsh abutting the temperate hardwoods, two small bay swamps along the west side of the upper end of the Stream 1e series, a band of hydric flatwoods on both sides of part of the upper stream and a thicker area of hydric flatwoods east of Stream 1ed, a moderately sized area of hydric palmetto prairie within the thicker area of hydric flatwoods, and a thickened wetland corridor--mixed wetland hardwood--along Stream 1ee. The long connected wetland of Stream 3e (G137), which is wetland forested mixed, connects to a headwater or flow- through wetland, whose southern component (G136) is also wetland forested mixed. These wetlands are moderate functioning. The remainder of the wetland upstream of Stream 3e is marsh (G135), wet prairie (G134), and mixed wetland hardwoods (G133); they are all high functioning. The narrow wetland corridor of Stream 3e? is high functioning. The headwater wetland of Stream 3e? is a freshwater marsh (G016) fringed on the south by wet prairie (G015) and the north by mixed wetland hardwoods (G014). The mixed wetland hardwoods is moderate functioning; the marsh and wet prairie are high functioning. Working downstream along Streams 3e and 3e?, IMC will reclaim a large freshwater marsh/shrub marsh complex, fringed by wet prairie, at the site of the large headwater wetland of Stream 3e?. In place of the ditch, where IMC will restore Stream 3e?, IMC will probably reclaim mixed wetland hardwoods. (At present, Map I-2 shows improved pasture, but that was before IMC agreed to reclaim Stream 3e?.) IMC will reclaim the wetland complex between Stream 3e? and 3e with the same vegetative communities, except that it will eliminate some of the present system's complexity by replacing the wet prairie with freshwater marsh. Although Map I-2 inadvertently omits any reclaimed wetland community along Stream 3e, Figure 13A5-1 shows reclaimed wetland forested mixed. There are four isolated wetlands in the vicinity of Stream 1e series. At the northern boundary of OFG is a small wet prairie (G027), which is high functioning. Just west of Stream 1ec is a small hydric flatwoods (G118), which is moderate functioning. Just south of this hydric flatwoods is a larger wet prairie (G119) with a small area of hydric flatwoods (G119A), which are both high functioning. Just east of Stream 1ec is a small wet prairie (G028), which is high functioning, even though it is ditched. IMC will reclaim the high-functioning wet prairie (G027) with a freshwater marsh, the small, moderate-functioning hydric flatwoods (G118) with hydric flatwoods and possibly part of one of the bay swamps, the high-functioning wet prairie/hydric flatwoods (G119) with rangeland abutting a freshwater marsh, and the small, high functioning wet prairie (G028) also with the upland community of rangeland. There are four isolated wetlands south and east of Streams 3e and 3e?. The two largest are freshwater marshes (G024 and G021) fringed by wet prairies (G023 and G022, respectively). These are all highest functioning, except that G023 is high functioning. The two smaller wetlands are wet prairies (G025 and G026), which are both very high functioning. IMC will reclaim all four of these wetlands at their present sites with the same communities, except that IMC will replace one very high functioning wet prairie (G026) with improved pasture. North of the headwater wetland of Stream 3e? are five isolated wetlands. The largest is a large freshwater marsh (G004) at the northeast corner of OFG. A wet prairie (G005) fringes the southern edge of this wetland complex, which is ditched. The marsh is high functioning, but the wet prairie is moderate functioning. Two smaller ditched marshes (G008 and G010) lie southwest of this large complex; they are moderate functioning. A small mixed wetland hardwoods (G007) fringed by a narrow wet prairie (G006), which are north of the two marshes, are moderate and low functioning, respectively. The final isolated wetland is a freshwater marsh (G012) fringed by wet prairie (G011) and connected by ditch to the G014 wetland complex. The marsh is high functioning, and the wet prairie fringe is moderate functioning. IMC will reclaim improved pasture at the sites of four of these five wetlands. At the site of the large freshwater marsh (G004), IMC will reclaim a freshwater marsh, which will be fringed by wetland forested mixed. The wetland forested mixed will be fringed by hydric oak forest, which will be fringed by palmetto prairie. IMC will mine 10,566 linear feet of streams, reclaiming 10,919 linear feet. The current condition of these streams has already been adequately addressed, largely by Mr. Kiefer's assessment in the Stream Reclamation Plan, described above. All the tributaries are Class III waters, although, as Deputy Director Cantrell testified, they might not meet all Class III water standards. In fact, it is unlikely, given the level of agricultural alteration, for these tributaries, both within and without the no-mine area, to meet all Class III standards. As Deputy Director Cantrell testified, the unditched streams are the Stream 1e series, Stream 3e, and Stream 5e, although upstream of OFG, Stream 5e and its headwater wetlands have suffered extensive agricultural impacts. With the exception of the Stream 1e series and probably Stream 3e, elevated levels of turbidity and nutrients and reduced levels of dissolved oxygen are to be expected in the water of the tributaries on OFG due to the extensive ensuing erosion and low- flowing characteristics of these streams. Mining Ditch and Berm System Six months prior to the commencement of mining of each block, IMC will construct a ditch and berm system between the block and the adjoining no-mine area. The ditch and berm system captures the stormwater runoff that would otherwise leave the mine site and releases the groundwater that would otherwise remain at the mine site. The phosphate mining industry began using ditch and berm systems during mining in the late 1980s and early 1990s. IMC has designed the ditch and berm system to capture the water from the 25-year, 24-hour storm event with several feet of freeboard. For storms not in excess of the design storm, the ditch, which runs between the berm and the mine cut, will carry water around the perimeter of the mining block. During periods of high rainfall, IMC will pump the water in the ditch into the mine recirculation system to prevent unintended discharges. When the mine recirculation system reaches its capacity, it releases excess water into Horse Creek upstream of OFG at two outfalls that have already received National Pollutant Discharge Elimination System (NPDES) permits for use with the Ft. Green beneficiation plant. Maintained during all phases of mining operations, ditch and berm systems have effectively protected water quality during mining operations. The only indication in this record of a breach of a ditch and berm system has been one designed to meet older, more relaxed standards. The other function of the ditch and berm system is to dewater the mine site and restore the water table to nearby wetlands in the no-mine area. The removal of the water from the surficial aquifer at the mine cut effectively lowers the water table by, typically, 52 feet, which is the average depth of the excavation at OFG. Lowering the water table in the mine cut by any sizeable amount creates a powerful gradient, which draws more water from the unmined, adjacent surficial aquifer to fill the void of the removed water. Unchecked, this process would fill the mine cut with water so as to prevent mining operations and empty nearby wetlands of water so as to deprive them of their normal water levels and hydroperiods. To prevent these diversions of the unmined surficial aquifer from taking place, pumps send the groundwater entering the mine cut into the mine recirculation system and ditch. To maintain adequate groundwater flow from the ditch into unmined wetlands, the ditch must maintain adequate water levels. While constructing the ditch and berm system, IMC will construct monitoring wells between the ditch and the wetland or surface water, which will indicate when groundwater flows are less than the pre-mining flows, for which IMC will have already collected the data. Varying permeabilities of adjacent soils or inadequate maintenance of the ditch may cause the system to fail to maintain the proper hydration of nearby unmined wetlands. Due to failures of its ditch and berm system, IMC has several times dewatered nearby wetlands. Recent failures occurred at the East Fork Manatee River in November or December 1999, the North Fork of the Manatee River in March 2000, and two more recent failures at the Ft. Green Mine. To maintain the ditch and berm system, an inspector will daily drive a vehicle along the top of the berm to check the berm and the water level in ditch. However, recharge wells are also necessary to ensure that the ditch and berm system prevents the dehydration of unmined wetlands is recharge wells. Recharge wells would reduce the frequency and extent of wetland drawdowns. Strategically located throughout the length of the ditch, recharge wells would be drilled into the bottom of the ditch to the intermediate or Floridan aquifer. By this means, recharge wells actively maintain appropriate water levels in the ditches and prevent drawdowns. IMC has several alternative sources for the water for these recharge wells: the water pumped from the surficial aquifer during the dewatering of the mine, the groundwater that has returned to areas already backfilled with sand tailings, or the water from the mine recirculation system, provided it is filtered. Notwithstanding testimony to the contrary, neither the CRP approval nor the ERP requires IMC to install recharge wells. These documents fail to impose upon IMC any specific action, if the monitoring wells reveal reduced or eliminated groundwater flows into the wetlands and surface waters. Both documents acknowledge the possibility that IMC may need to install recharge wells to recharge the ditch. In his testimony, Dr. Garlanger recommended the installation of floats on the top of each recharge well to allow the inspector visually checking the ditch and berm readily to check each recharge well at the same time. Clearly, the presence of floats atop recharge wells would allow early identification and repair of malfunctioning recharge wells, prior to the loss of water from the ditch and the dehydration of nearby unmined wetlands. 2. Mine Recirculation System In addition to recycling the water used in mining operations, the mine recirculation system draws on sources deeper than the surficial aquifer, as well as rain. Water leaves the mine recirculation system through evapotranspiration and surface runoff. When water leaves the system as runoff, during or after major storm events, it does so through NPDES outfalls, and the high water volumes associated with the storm generally assure that any contaminants in the discharged water are sufficiently diluted. 3. Sand Tailings Budget For OFG, IMC has presented a reasonable sand tailings budget. Dr. Garlanger, whose expertise in geotechnical matters finds no match on the opposing side, has opined that the supply is ample. Charlotte County and the Authority have challenged the adequacy of the sand tailings budget. In part, Charlotte County and the Authority base their challenge to the sand tailings budget in part on an earlier comment by Dr. Garlanger concerning changing volumes of sand tailings, but he adequately explained that their reliance was misplaced. As noted above, the sand tailings budget at OFG requires sand from the Four Corners and Ft. Green mines. Conjuring up images of a sand Ponzi scheme, Charlotte County and the Authority seem to argue, in part, that there are not enough sand tailings, and DEP has allowed phosphate mining companies that have run out of nearby sand to substitute a Land-and-Lakes reclamation for the more sand-intensive reclamation that had originally been permitted and approved. OFG is early enough in the post Land-and-Lakes reclamation era that, if sand tailings from post-reclamation excavations are being moved around, OFG will get them. The obligation imposed upon IMC to obtain sand tailings backfill is not contingent upon feasibility; IMC must backfill the mine cuts with sand. The possibility that DEP would allow OFG to abandon one of the central tenets of this reclamation project by substituting Land-and-Lakes reclamation for topographic replication is inconceivable. Reclamation BMR Reclamation Guidelines BMR program administrator James (Bud) Cates supervises reclamation by the phosphate mining industry. Mr. Cates and Janine L. Callahan, also of BMR, prepared a document entitled, "Guidelines for the Reclamation, Management, and Disposition of Lands within the Southern Phosphate District of Florida" (Reclamation Guidelines). The document is dated August 2002. Although it is marked, "draft," Reclamation Guidelines is a revision of the first draft, which was prepared in 1993. The Administrative Law Judge commends the authors and DEP for the close attention to detail that has resisted finalization for nine years, but it would be imprudent to disregard the second draft while awaiting the next novennial revision, especially when DEP offered it as an exhibit (DEP Exhibit 37). Consistent with an emphasis on functional analysis and the creation of vegetative, hydrologic, and soils conditions that facilitate self-organization, Reclamation Guidelines defines "reclamation" as: the attempt to identify and replace those components/parameters of a community, resulting in the creation of a functional natural community analog. Emphasis is placed on the creation of functional soil, hydrology, and floral precursors that serve as the basis for food-web development. Because of the ecological need for fully functional communities, analogs are typically designed on a whole habitat basis rather than being designed around the specific needs of one or two species. These analogs are designed to incorporate a maximum initial diversity potential, based upon the premise that with proper management, the initial input will yield, over time, maximum ultimate diversity. Reclamation plans for and the activities used to create these replacement communities will be guided by existing knowledge of earthmoving, soils, hydrology, vegetation, general ecology, and wildlife management. Data in every applicable field should be constantly collected and used to increase knowledge and improve the results of the reclamation of natural community analogs. Focusing on specific reclamation techniques for soils, Reclamation Guidelines adds: The use of Topsoil/Vegetative Inoculum (T/VI) is extremely important to the introduction of organic matter, soil microbes, mycorrhizae, and plant propagules. These factors are critical to the creation of a living soil precursor. The T/VI is also the best known source of plant propagules that will provide the diversity inherent in a given community. Therefore, to the extent of material availability and economic feasibility, T/VI is recommended for use in the replacement of natural community analogs. The goal should be a three to six inch average depth with a minimum depth of no less than one inch over the base of sand, overburden, or sand/overburden mixture. Where T/VI availability problems occur, an artificially created topsoil precursor may be used in combination with all available T/VI or as a replacement for T/VI. Topsoil precursor may be created by incorporating a mixture of overburden, clay, and organics (hay mulch, wood chips, manure, green manure, or combinations thereof). All artificially created topsoil precursors should contain an organic portion and should be treated with microbial and mycorrhizal inoculum. For Sandhill, which has the least burdensome requirements among the three habitats most analogous to sand live oak (sand pine scrub, xeric oak scrub, and sandhill), Reclamation Guidelines notes that the objective is to concentrate a "deep layer of well-drained sands around/upon a topographic high to prove an area of rapid, positive infiltration and positive down-gradient seepage." The reclaimed sandhill habitat is adapted to excessively drained sands and requires "substantial depth to water table (although not as excessive or deep as scrub)." For soils, Reclamation Guidelines offers two options: six to eight feet of sand tailings covered with a layer of T/VI from a suitable donor scrub or eight to ten feet of sand tailings covered with a minimum four inch layer of artificially created topsoil precursor. For sand pine scrub and xeric oak scrub, the soil requirements are the same, except that the first option is for sand tailings eight to ten feet deep, not six to eight feet deep. As already noted, CRP Specific Condition 8.b requires IMC to reclaim sand live oak and xeric oak scrub with "several feet" of sand tailings and three to six inches of topsoiling from donor scrub or, if topsoiling is not feasible, the seeding and disking of a green manure crop. (Although omitted, the feasibility condition presumably qualifies the topsoiling requirement because Specific Condition 8.b defines "feasible.") For Pine Flatwoods and Dry Prairie, Reclamation Guidelines notes that the objective is to locate these communities on moderately to poorly drained soils, so that the depth to the water table is moderate to shallow. Most vegetation of these two communities is adapted to predominantly sand soils. For soils, Reclamation Guidelines offers two options: two to four feet of sand tailings covered with a layer of T/VI from a suitable donor flatwoods/dry prairie area or two to four feet of sand tailings covered with a minimum four inch layer of artificially created topsoil precursor. As already noted, CRP Specific Condition 8.a requires IMC to reclaim pine flatwoods and dry prairie with a minimum of 15 inches of sand tailings and three to six inches of transferred or stockpiled topsoil, if feasible, or, if not, the seeding and disking of a green manure crop. For Wetland Mixed Forest, Reclamation Guidelines notes that this community will occupy the outer limit of the floodplain down to the stream channel and the forested edge of deeper marshes. Likely to receive runoff from major storm events, Wetland Mixed Forest should be designed to contain and slow runoff while maintaining sufficient water for wetland viability. For soils, Reclamation Guidelines offers three options: decompacted overburden to a depth below the dry season water table overlying by a layer of T/VI from an appropriate donor site, two to three feet of sand tailings under a layer of T/VI, or either overburden or two to three feet of sand tailings covered by a minimum of four inches of artificially created topsoil precursor. As already noted, ERP Specific Condition 14.b requires IMC to reclaim all forested wetlands by backfilling with sand tailings or overburden to an unspecified depth under "several inches of wetland topsoil," if feasible. However, for bay swamps, Specific Condition 14.b adds in boldface: "All reclaimed bay swamps shall receive several inches of muck directly transferred from forested wetland approved for mining." Reclamation Guidelines treats Bay Swamp (and Cypress Swamp) separately from other forested wetlands. Noting that Bay Swamps are in areas of significant surficial seepage or high average groundwater elevation, Reclamation Guidelines states that Bay Swamps require sufficient seepage to remain saturated or a deep organic profile at and below the average water table elevation. For soils, Reclamation Guidelines states: "Bay swamps require the placement of one to three feet of organic muck as a depressed lens. The muck should be obtained from a suitable donor wetland." For Non-Forested Wetland, which includes wet prairies and freshwater marshes, Reclamation Guidelines is of value more to identify why the phosphate mining industry and DEP have overseen the routine reclamation of deeper wetlands, but not shallower wetlands. Treating these two very different communities under the same category, Reclamation Guidelines states: "All of the sub-categories may be constructed on overburden, with the exception of sand pond." Although the overburden option for reclaimed forested wetlands seems a stretch, given repeated problems of mature tree growth into overburden relatively close to grade, the overburden option for reclaimed wet prairie, other than fringing deeper marshes when properly sloped, can no longer merit serious consideration, given only one successful, extensive shallow-wetland reclamation site--SP(2D), whose reclaimed soil is four inches of mulched topsoil overlying four feet of sand tailings. However, consistent with its Reclamation Guidelines, DEP did not differentiate between wet prairies and deep marshes in the soil-reclamation requirements contained in the ERP. ERP Specific Condition 14.c allows backfilling with sand tailings or overburden and requires only "several inches of wetlands topsoils when available." Tellingly, Reclamation Guidelines divides aquatic systems into two categories: shallow (less than six feet deep) and deep. Shallow systems comprise swamps, marshes, sloughs, and ponds, but not streams. Nowhere does Reclamation Guidelines explicitly address the reclamation of streams. Comparing the soil-reclamation requirements that DEP has imposed on IMC in the CRP approval and ERP to the soil- reclamation specifications stated in BMR's Reclamation Guidelines, material discrepancies emerge as to the depth of sand tailings underlying four upland communities. If IMC transfers topsoil, sand live oak communities require at least six feet of sand tailings, not "several" feet; if IMC uses green manure, sand live oak communities require at least eight feet of sand tailings. Regardless whether topsoiled or green manured, xeric oak scrub communities require at least eight feet of sand tailings, not "several" feet. Regardless whether topsoiled or green manured, pine flatwoods and palmetto prairie require at least two feet of sand tailings, not 15 inches. There is a material discrepancy between the ERP and Reclamation Guidelines as to bay swamps. Reclamation Guidelines specifies one to three feet of organic muck for reclaimed Bay Swamps. ERP Specific Condition 14.b requires only "several inches of muck." Given the poor record reclaiming bay swamps, DEP, in forming this condition, is not relying on any experience-based knowledge that it has acquired, or, if it is, it did not add this information to the present record. There is no discrepancy as to wet prairies, but this is clearly due to a shortcoming in Reclamation Guidelines, at least as to non-fringe wet prairies. Under Reclamation Guidelines, wet prairies, at best, will continue to reclaim only as fringes, and only then if the edges of deeper wetlands have shallow slopes. Given the otherwise-uniform failure to reclaim extensive shallow wetlands, the actual soil regime at SP(2D) of four feet of sand tailings under four inches of topsoil must set the minimum soil criteria for wet prairie. 2. Geology and Soils For purposes of this Recommended Order, soils occur predominantly in the first two meters of the earth's surface. Below that depth, geologic characteristics predominate, so this Recommended Order refers to these deeper structures as geology. Post-reclamation, all of the soil and the top 45-50 feet of the geology are a product of IMC's reclamation activities. The post-reclamation geologic characteristics follow from the mining process, which deposits overburden within the mine cut in two locations. Most of the overburden is deposited in spoil piles within the cut. Some of the overburden is piled against the sides of the mine cut to reduce the seepage of water from the surrounding surficial aquifer into the cut. Both types of overburden are sometimes called "cast overburden." At OFG, prior to backfilling, the creation of cast overburden spoil piles will either leave alternating bands of sand tailings valleys and cast overburden spoil piles, each 330 feet wide, or each 165 feet wide; the record is not entirely clear on this point. The scenario with the greater hydrological impact is that each valley and the base of each spoil pile is 330 feet wide, but, even under this scenario, relatively little backfilled area would have less than five feet of sand tailings. If each sand tailings valley is 330 feet and each cast overburden spoil pile is also 330 feet at its base, the profile of each cast overburden spoil pile would appear to be a two- dimensional pyramid with its top cut off just below midpoint along its two slopes. The sides of the spoil piles of cast overburden are not perpendicular to the surface, but are sloped at about 1.5:1, according to Dr. Garlanger. Rounding off the depth of the mine cut to 50 feet, this 33-degree slope would travel 50 feet vertically at the point at which it had traveled 75 feet horizontally. Matching this slope with another on the other side of the spoil pile, 150 feet of the 330-foot wide overburden spoil pile would be consumed by the sloped sides, and 180 feet would be a plateau, at a constant elevation of 50 feet above the bottom of the mine pit. Adding 7.5 feet on either side of the plateau gains a depth of 5 feet, so the width of overburden under less than five feet of sand tailings would be 195 feet. Under the less-favorable scenario, for a 660-foot wide band of reclaimed geology, without regard to topsoil additions, the sand tailings, for the above-described 660-foot slice, will be at least 10 feet deep for a distance of 450 feet, or 68 percent of the reclaimed area, and will be at least 5 feet deep for a distance of 475 feet, or 72 percent of the reclaimed area. Adding the U-turns at the end of the rows would add only a little more area to the 28 percent of the reclaimed area with an overburden plateau within five feet of the surface. If the cast overburden spoil piles fill only half of each 330-foot wide cut, then the overburden plateaus would be much narrower. Each sand valley of 165 feet would abut a 33-degree slope that would again run 75 feet horizontal while climbing 50 feet vertical. Two of these slopes would consume 150 feet horizontal, leaving an overburden plateau of only 15 feet, leaving much less land with an overburden plateau within five feet of the surface. The shaping of the overburden that precedes the backfilling, the backfilling of sand tailings, and the transfer of topsoil are aided by substantial technological improvements in earthmoving equipment in recent years. Most importantly, earthmoving equipment has incorporated global positioning systems, so that they can now grade material to a tolerance of two centimeters, as compared to tolerances of six inches and one foot not long ago. This achievement permits the reclamation scientists to supervise backfilling more closely so as to replicate the design topography, which is a necessary, although not sufficient, condition of successful establishment of targeted hydroperiods and inundation levels. IMC soil scientist Joseph Schuster and Mr. Carter both presented detailed, well-documented testimony and are both competent soil scientists. They start from the same point, which is that pedogenesis, or soil formation, is a function of five factors: parent material, relief, climate, vegetation, and time. From there, they travel separate paths in their analysis and conclusions concerning the soil aspects of IMC's reclamation plan. In the successful reclamation of soils, Mr. Schuster highlights the creation of appropriate drainage characteristics, and Mr. Carter highlights the creation of appropriate soil horizons, although both experts acknowledge the importance of both these factors, and others, in soil formation and function. Their reasoning seemed mostly to be a question of differing emphases, although their conclusions were mutually exclusive. As already noted, the A horizon is the topsoil layer. (A mucky wetland may have an O horizon.) There is some variability among horizons--for example, the C horizon, which is described below, may occur immediately beneath the A horizon, especially in sandy material. But, for this part of Florida, typically, the E horizon forms under the A horizon. The E horizon is a leaching zone, through which rainwater transmits substances from the A horizon down to the B horizon, which is the accumulation zone beneath the E horizon. Florida typically has two types of B horizons: the Bh (or spodic) horizon, which is composed of loamy or spodic materials, and the Bt (or argyllic) horizon, which is composed of clayey materials. The spodic horizon is a mineral soil horizon containing aluminum and organic carbon, and possibly iron, which formed in a much colder climate, probably at least 10,000 years ago. Spodic horizons typically occur in the top two feet of the soil profile. Although spodic horizons may occur as deep as 40 feet, they occur at OFG within 20 inches of the surface, sometimes within only 10 inches. Beneath the B horizons is the C horizon, which is the parent material for pedogenesis. For the most part, Mr. Schuster's emphasis on reclaiming appropriate drainage is credited as the single most important factor in reclamation, and his seven drainage categories are ample for guiding the reclamation of the drainage characteristics of soils. More reclamation failures may necessitate the implementation of one of Mr. Carter's suggestions to carefully restore the soil horizons within the top two meters of the mine cut, as it is backfilled, or to use more clayey soils, such as those from drained CSAs, to add more nutrient-retaining capacity to the B and C horizons than nutrient-poor sand tailings provide. Mr. Carter's soil cores from reclamation sites, which reveal overburden close to the surface, presented stark contrasts to soil cores of native soils in the area, although drainage concerns outweigh pedogenic concerns. Mr. Carter correctly points out that, from a soils perspective, pre-mining overburden is not post-reclamation overburden. From a mining perspective, what lies above the unmined phosphate ore is overburden, and what lies in the ground, post-reclamation, is also overburden, which, to a certain depth, is dominated by characteristics of the B horizon and underlying C horizon. However, in a 52-foot deep phosphate mine, as opposed to typical road construction, which Mr. Schuster unpersuasively offered as a comparable, the overburden is ultimately dominated by geologic material from below the C horizon. From a soils perspective, what lies in the unmined ground are soil horizons that took many years to form, and what lies in the ground, post- reclamation, is nothing but an admixture of former soil horizons and geologic material that normally resides a little deeper in the earth's crust. As Mr. Carter notes, the result, post- reclamation, is less like soil and more like unconsolidated soil material with little horizonization even several years after reclamation, and, if an overburden layer is present close to the surface, it typically is tightly compacted. Soil horizons are not an incidental or random characteristic of undisturbed soils; soil horizons are an important component in the formation and functioning of soil. Mr. Schuster himself disclaims reliance upon overburden epipedons--which are organically influenced horizons typically above the B horizon--in the restoration of native ecosystems, although he does not object to the presence of such epipedons in agricultural restoration. If sand were displaced by overburden in the area of the E horizon, the E horizon will be unable to contribute to the formation of the B horizon, as it must, especially after the comprehensive disturbance of all soil horizons contemplated at OFG. Mr. Schuster's disclaimer bodes ill for the ERP provisions allowing overburden as an alternative to sand tailings for forested and herbaceous wetlands. However, Mr. Schuster's disdain for cast overburden near the surface is well-founded. His emphasis on drainage over soil horizons, including even overburden epipedons, may find support at Dogleg, which, according to the CDA, suffered the loss of its 12-inch topsoil layer due to oxidization and was left with overburden of a "clayey sand" texture that may have been more permeable than typical, less permeable overburden. This loss appears to have taken place over sufficient time that other conditions may have commenced to form an A horizon. However, when adjacent mining ended and the water table re-established itself, the reclaimed trees began to survive. Mr. Schuster accounts for the importance of pedogenesis, in addition to drainage characteristics, by identifying the topsoil/green manure, sand, and overburden as analogs of soil horizons. Certainly, the topsoil/green manure is a functional analog, and its thickness is not much of a variable. Sand tailings provide an appropriate texture for an A horizon. But the variability of the depths of sand tailings limits the force of Mr. Schuster's argument for functional analogs. For all wetland communities, overburden may occur at depths of only several inches, and, for pine flatwoods and palmetto prairies, overburden may occur at depths of 15 inches. Or sand tailings may be over 50 feet deep, atop a clay confining layer, not overburden. Setting aside the problem with the variability of depths of sand tailings, it is possible to treat sand tailings as a functional E horizon, through which materials will leach from the A horizon and into the B horizon, which is the zone of accumulation. However difficult it may be to cast the sand tailings in the role of a B horizon, it is impossible to cast them in the role of a C horizon. Ignoring the considerable amount of geologic material contained in cast overburden and possible textural issues, Mr. Schuster plausibly offers overburden as good B and C horizon material because of its higher clay or spodic content. Thus, the apparent impairment of pedogenesis may not be as extensive as first appears, provided overburden remains below the A and E horizons. Still, mining and reclamation, at least as designed for OFG, mean the loss of some soil functions for extensive periods of time, but proper reclamation of drainage characteristics and hydrology sufficiently mitigate these losses of function. Even Mr. Schuster's emphasis on drainage is not unconditional, as he relies on the application of topsoil or the implementation of a green-manure process to provide an immediate A horizon and accelerate the process by which the A horizon continues to form. Endorsed by Mr. Carter as a good idea to increase organic material and loosen the structure of the topsoil, green manure is the process by which a quick-growing cover crop is planted on the finished surface, post-reclamation. The crop is then disked into the soil to provide a quick infusion of nitrogen and organic matter. This approach has not previously been used in reclamation following phosphate mining, but it has been used in other applications and is effective. Post-reclamation, fire too will pump nutrients into the A horizon. Herbaceous wetlands, with their shallower roots, ought to be adequately served by Mr. Schuster's focus on the drainage characteristics of reclaimed soils. Forested wetlands present a different challenge due to their deeper root systems. Past reclamation of forested wetlands has experienced tree loss after several years of growth, possibly indicative of a problem with root development beyond a certain depth. Perhaps the roots cannot penetrate the overburden or cannot find the necessary nourishment, after penetrating the overburden; however, it is at least as likely, given the record of reclamation, that the mitigation site suffered from a poorly reclaimed water table, so that, for example, the water table was too high for too long, perched, or even too low for too long. Given the repeated problems with establishing appropriate water tables, post-reclamation, this factor looms as a likely explanation for tree die-off. However, Mr. Schuster's emphasis on drainage characteristics over pedogenic conditions carries more weight as to herbaceous wetlands and xeric habitats, where sandy soils predominate to relative great depths, and somewhat less weight as to forested wetlands. Mr. Schuster's emphasis on drainage over pedogenesis carries even less weight as to pine flatwoods and palmetto prairies, which are less tolerant to the disturbance of the spodic horizon in reclaimed soils. Obviously, overburden presents different textures and drainage characteristics than do native flatwoods soils. However, pine flatwoods and palmetto prairies are more dependent upon higher water tables than more xeric upland communities, so, again, past problems in reclaiming these upland communities again likely involve the failure to create an appropriate water table, post-reclamation. Differences between Mr. Schuster and Mr. Carter were harder to reconcile regarding the role of pH in soil. Mr. Schuster and Mr. Carter reached different results in field tests of soil pH. However, Mr. Schuster's testimony is credited that most ecosystems tolerate a wide range of pH, and the most important soil characteristic remains its drainage characteristics. Hydrology Introduction Removing and replacing the topography, soils, and geology, including the surficial aquifer, to a depth of 52 feet, under nearly 3500 acres of land necessitates hydrological analysis. Hydrological analysis is necessary to support three sets of projections: the streamflows of Horse Creek, downstream of OFG, during mining and after reclamation; hydroperiods and inundation depths of reclaimed wetlands, as the wetlands created in the reclaimed topography and soils fill and empty with water based on inputs and outputs from runoff and groundwater, inputs from rainfall, and outputs from evapotranspiration; and peak discharges from OFG, during mining and after reclamation. All hydrological analysis must account for the water budget, which balances the inputs and outputs of water. The elements of the water budget are rainfall, runoff, percolation (or infiltration), evapotranspiration, deep recharge (the recharge of the deeper aquifers), and groundwater outflow. Rainfall is the most important factor because it is the sole means by which water enters the system. Equal to the total of the outputs, annual rainfall is a large number, typically measuring in this part of Florida in excess of 50 inches. Rainfall is also a variable number in two respects. It varies from year to year. For the Peace River basin, annual rainfall from 1933 to 2002 has ranged from 35.89 inches to 74.5 inches with an average of 52.4 inches. However, rainfall in the Peace River basin has varied over eras. From 1933 to 1962, average annual rainfall was 55.48 inches. From 1962 to 2002, average annual rainfall was 51.02 inches. For the Peace River basin, the average annual rainfall has decreased about 4 1/2 inches in the past four decades when compared to the preceding three decades. Especially over shorter time intervals, rainfall also varies considerably from location to location within a relatively small area. Subject to these variabilities, especially the distance of the rainfall gauge to the location for which the water budget is constructed, rainfall is easily measured by rainfall gauges. Measurement means straightforward collection of data without elaborate modeling, calculation, or simulation. After rainfall, the most important element in the water budget is evapotranspiration, which is the combined effect of evaporation of water from soil, plant surfaces, wetlands, and open water and transpiration of water through vegetative processes. In this part of Florida, evapotranspiration releases about 75 percent of the rainfall back into the atmosphere, which, by convention, counts as a loss to the system. Unlike rainfall, evapotranspiration typically cannot be measured, except that the maximum evaporation, which is a pan containing water in the direct sun, is subject to direct measurement. Hydrologists have measured evapotranspiration from irrigated golf courses at 58-62 inches annually, and Dr. Garlanger has measured evapotranspiration from reclaimed CSAs at 39-41 inches annually, although both of these measurements may have been somewhat indirect. However, hydrologists widely recognize ranges of evapotranspiration for this part of Florida for different land uses. Annual rates of evapotranspiration for open water is 49-1 inches, for riparian wetlands is 47-49 inches, and for isolated wetlands is 43-44 inches. The annual evapotranspiration for pine flatwoods is 37-39 inches and for xeric uplands is 34-36 inches. Impervious surface, such as pavement or a roof, produces only 8-10 inches annually--absent weeds, all evaporation. In addition to land use, the amount of water available controls the amount of evapotranspiration. Elevations of the water table will affect evapotranspiration. Thus, hydrologists often measure potential and actual evapotranspiration. Anthropogenic impacts may increase or decrease evapotranspiration. Net additions of impervious surface, such as parking lots, roads, and rooftops, increase runoff and decrease evapotranspiration. Net additions of open water, such as lakes, ponds, and streams, decrease runoff and increase evapotranspiration. At the other end of the spectrum, deep recharge removes very little water at OFG. Even during mining, when the impacts would be greatest due to high withdrawals, the increase to deep recharge is 30-60 gallons per minute--insignificant as compared to the average recharge rate in the Peace River basin of 190,000 gallons per minute. In fact, according to RAI-192 in the CDA, rainfall, not deepwell water, is the primary source of water for the mine recirculation system. Deep recharge is typically one inch annually, although Charlotte County hydrologist Phillip Davis, in one of his scenarios, claimed that 2.5 inches of water annually would enter the intermediate aquifer from the surficial aquifer. This range of values for deep recharge is within the specified ranges for most types of evapotranspiration. Deep recharge cannot be directly measured. The record does not suggest much variability in deep recharge, which is controlled by the elevation of the water table and potentiometric surface of the Florida Aquifer, in undisturbed geologic systems in this part of Florida. Although the replacement of part of the confining layer between the surficial and intermediate aquifers could affect deep recharge, the potential impact at OFG appears to be very small due to the permeability of the matrix layer and impermeability of the clay bed beneath it. However, historic anthropogenic disturbances may have increased deep recharge. All groundwater withdrawals induce recharge, at least of the surficial aquifer. Withdrawals from the deeper aquifers, such as those taken by the phosphate mining industry prior to expanded recycling, could have caused increased rates of deep recharge, depending on the confining layers above the Floridan Aquifer within the area influenced by the withdrawals. To the extent that the effect of these deep withdrawals extended to the surficial aquifer, evapotranspiration and streamflow would have been reduced. Groundwater outflow has been measured in this area by Bill Lewelling of the U.S. Geologic Service. (Mr. Lewelling seems to have measured groundwater outflow indirectly by measuring chloride concentrations at different locations.) He found a range of 1.7-17.9 inches annually with an average of 9.2 inches annually. An important component of groundwater outflow, infiltration depends on soil type and antecedent saturation, so it is variable in terms of location and climate. However, it appears to vary within a relatively narrow range at OFG, pre- mining. One combination of water-budget elements that may be measured easily is streamflow, which, as noted above, is a combination of the runoff and groundwater outflow reaching the stream. Streamflow equals rainfall minus evapotranspiration minus deep recharge minus the change in uplands storage. For the purposes of Dr. Garlanger's analysis, uplands are everything, including wetlands, above riparian wetlands, and riparian wetlands are the area adjacent to a stream channel that remain perennially wet and are typically within the 25-year floodplain. Streamflow is not variable like rainfall as to location because the river or stream is fixed and so is the location of the gauge, but streamflow is highly variable as to volume, even from year to year. For Horse Creek at State Road 64, for example, annual streamflow from 1977 to 2001 has averaged 9.7 inches, but has ranged from one inch to 17 inches. For the Peace River at Arcadia, annual streamflow from 1950-1962 was 13.25 inches or 1334 cfs. From 1963 to 2002, average streamflow at the same location was 8.78 inches or 884 cfs. The SWFWMD has not yet set minimum flows and levels for the Peace River, but is presently in the process of setting these values. In these cases, streamflow is most often calculated to compare a model's output in streamflow to measured values for the same period of time, to determine streamflow for locations without a streamflow gauge, or to determine streamflow for locations with a streamflow gauge, but after changes in land use, such as the construction of a ditch and berm system or post-mining reclamation. Another combination of water-budget elements that can be measured, although with more difficulty than streamflow, is the water table. Most water table data are fairly recent, dating from the early 1990s. Mr. Davis testified that the water table data available for OFG were the most limited that he had ever encountered. Varying daily, the water table is the top of the surficial aquifer. The elevation of a non-perched water table, at any given time, is ultimately driven by all of the elements of the water budget, but is immediately reflective of surficial aquifer inputs and outputs and hydraulic conductivity. Hydraulic conductivity is the ability of a porous medium to transmit a specific fluid under a unit hydraulic gradient, so it is highly dependent on the physical properties of the medium through which the fluid is transmitted. Although hydraulic conductivity exists in the horizontal and vertical planes, this Recommended Order considers only horizontal hydraulic conductivity. Hydraulic conductivity is an important hydrological factor that can be measured, at least horizontally, although with difficulty. Hydraulic conductivity varies by location due to the variations in permeability of the geological structure through which the groundwater is passing. The hydraulic conductivity of sand tailings is about 38 feet per day, and the hydraulic conductivity of cast overburden is about one foot per day. Native soils are typically somewhere in between these two extremes. In one area, the matrix, pre-mining, had a permeability of 5-15 feet per day. IMC's assurances concerning streamflow, wetlands hydroperiod and inundation depths, and peak discharges must be assessed against three different backdrops. At one extreme, at least based on the present record, phosphate mining and reclamation, as distinguished from other phases of phosphate processing, have not caused adverse flooding; the sole example of flooding from a failed ditch and berm system--designed to meet more relaxed standards--occurred at the Kingsford Mine on January 1, 2003, and no serious environmental damage occurred. At the other extreme, reclamation after phosphate mining has routinely failed to reclaim targeted hydroperiods and inundation depths for shallower wetlands and many forested wetlands. In between these two extremes, although closer, at least recently, to the industry's flooding experience, is streamflow. Historic impacts to the Peace River are considered below, but an example of the minimal impact on streamflow of recent mining is found in the last 15 years' mining of the upper reaches Horse Creek. During this period, the streamflow of Horse Creek at State Road 64 has remained unchanged. The record does not support Mr. Davis's suggestion that high volumes of groundwater pumping and high volumes of NPDES discharges artificially added streamflow during this period. Resolution of the hydrological evidence in these cases requires close examination of the testimony of Dr. Garlanger, who addressed all three areas for IMC; Mr. Davis, who addressed streamflow and wetland hydroperiods and inundation depths for Charlotte County; and Mr. Loper, who addressed peak discharges for Charlotte County. All three of these witnesses are highly competent and patiently and thoroughly explained their hydrological analyses. Mr. Loper proved adept at finding flaws in IMC's analyses of peak discharges. Dr. Garlanger and his staff several times refined their work, even during the hearing, to incorporate Mr. Loper's findings. Differences remained between Mr. Loper and Dr. Garlanger, and, although it is possible that Mr. Loper is correct on these remaining points, Dr. Garlanger successfully discounted the importance of Mr. Loper's objections in projecting peak discharges. Examining the evidence in the backdrop of a record almost devoid of failures that have resulted in flooding, it proved impossible not to credit Dr. Garlanger's assurances about peak discharges. Mr. Davis was less successful in finding flaws in IMC's analysis of streamflow, or at least in finding material flaws. As detailed below, his theory attributing to phosphate mining a greater share of historic reductions in the streamflow of the Peace River seems less likely than Dr. Garlanger's theory attributing a lesser share of these historic reductions to phosphate mining. Mr. Davis substituted an integrated simulation model for Dr. Garlanger's uplands model and spreadsheet. The advantages of Mr. Davis's model emerged to a greater extent in simulating wetlands hydroperiods and inundation depths, not in simulating streamflows. This is discussed in detail below. The conflict between Mr. Davis and Dr. Garlanger over the ability to reclaim targeted hydroperiods and inundation depths has proved very difficult to resolve. Dr. Garlanger has vast experience in the phosphate mining industry and thus a clear advantage in projecting, as he has since 1974 at several hundreds of projects, peak discharges and streamflow. But this experience is no advantage as to projecting wetland hydroperiods and inundation depths. Dr. Garlanger did not state that he has projected hydroperiods and inundation depths for 30 years at several hundreds of projects. If he has done so, he has contributed to the numerous failures, described above, of reclaiming shallow wetlands. More likely, the phosphate mining industry has infrequently targeted shallow wetlands for reclamation, so Dr. Garlanger does not have extensive experience in creating the necessary hydroperiods and inundation depths for shallow wetlands. The reclamation of specific hydroperiods and inundation depths for shallow wetlands is likely a fairly recent development, perhaps due to the relaxed restoration expectations of earlier eras or the inability of earthmoving equipment to execute fine specifications in finished topography. In the CDA discussion of Bay Swamp, noted above, the author admits that reclamation historically has not attempted to reclaim the kind of interface necessary between shallow wetlands and the water table to support bay swamps. The parties' understandable, but unrealistic, pursuit of findings that all previous shallow-wetland reclamations of any size have failed or succeeded may have discouraged testimony candidly analyzing what hydrologists have learned from the limited successes and the many failures. Especially unfortunate is the omission of any discussion of the success of Dogleg, where, according to the CDA material, persistent replanting of trees over many years in soils with prominent, but perhaps atypically permeable, cast overburden profiles eventually succeeded, after the completion of nearby mining allowed the water table to reestablish itself. The record does not even indicate if Dogleg mining took place behind a ditch and berm system, nor does it adequately describe the texture of the overburden on which the topsoil rested. In addition to different levels of confidence attaching to the demonstrated ability of the phosphate mining industry to avoid adverse flooding and significant reductions in streamflow, on the one hand, and the routine inability of the phosphate mining industry to re-create the hydroperiods and inundation depths required for shallow wetlands, another point of differentiation exists between Dr. Garlanger's streamflow projections and his hydroperiod and inundation depth projections. Although he uses the same uplands model and similar wetlands models for both tasks, certain characteristics of his relatively simple modeling do not work as well in projecting hydroperiods and inundation depths as they do in projecting streamflows. Accurate projections of streamflow, at a discrete point downstream of the 4197 acres constituting OFG, are amenable to averaging, smoothing out input values, and substituting assumed values for calculated values. Accurate projections of hydroperiods and inundation depths require precise analysis of reclaimed wetlands--few over 10 acres, most less than a couple of acres--distributed over the 3477 acres of OFG to be mined. For each wetland, precision means daily accuracy to within a few inches of elevation of topography and water table and no more than a few feet of hydraulic conductivity. Streamflow projections, which have worked in the recent past, will continue to work, whether each projection within an area is accurate or any errors within an analyzed area offset errors in other areas, so that, notwithstanding flow discharge curves, small discrepancies in projected streamflow average out over longer periods of time. Hydroperiod and inundation depth projections, which may have been attempted, if at all, only rarely in the past, must be accurate over very small areas for very specific time intervals. Also, streamflow projections are less sensitive to misallocations between runoff and groundwater flow than are projections of shallow wetland hydroperiod and inundation depth. The record suggests that reclaiming short wetland hydroperiods and shallow inundation depths places new and more difficult demands upon the phosphate mining industry and its reclamation scientists. Although long accustomed to producing projects that did not flood and at least recently accustomed to producing projects that did not reduce streamflow, the phosphate mining industry and its reclamation scientists are only now acclimating to newer regulatory expectations that they produce projects that reliably reclaim shallow wetlands by re-creating functional relationships between these wetland systems and surface runoff and groundwater flow. Streamflow Streamflow in Horse Creek downstream of OFG and the Peace River is reduced during mining because the ditch and berm system captures all of the runoff, at least up to the capacity of the ditch and berm system. The ditch and berm system is designed to handle the 25-year, 24-hour storm event, although additional, unspecified freeboard is built into the system. The capacity of the ditch and berm system may be exceeded by more intense storms or perhaps even lesser storms, unless the 25-year storm design accounts for antecedent water levels, which may be higher in systems with recharge wells than in systems without the recharge wells. In any event in which the capacity of the ditch and berm system is exceeded, IMC pumps the water through the mine recirculation system and releases it through one of two NPDES outfalls upstream at Horse Creek. Because the ditch and berm system captures all of the runoff, under normal conditions, the reduction in streamflow after reclamation is generally less than the reduction in streamflow during mining. The removal of the ditch and berm system allows runoff again to contribute to streamflow. To analyze the impacts upon streamflow, Dr. Garlanger first performed a simplified water budget analysis at three locations: Horse Creek at State Road 72 (near Arcadia), the Peace River at Ft. Ogden (where the Authority withdraws its raw water--downstream of the confluence of Horse Creek and the Peace River), and the point at which the Peace River empties into Charlotte Harbor. Although Dr. Garlanger used uplands exclusively for this simplified exercise in constructing a conceptual water budget, adding the riparian wetlands would not substantially change the result because the wetlands runoff and evapotranspiration would be higher, but the wetlands groundwater outflow would be lower. Either way, Dr. Garlanger's analysis, which is sometimes called an analytic model, was merely a prelude to more sophisticated modeling. For his during-mining analysis, Dr. Garlanger assumed that the ditch and berm system would capture all the runoff from the 5.4 square miles of the Horse Creek sub-basin behind the ditch and berm system. In sequential mining, the ditch and berm system would not capture all of the 5.4 square miles at once. But, assuming the worst-case scenario, Dr. Garlanger assumed the capture of the runoff from entire sub-basin for a period of 25 years. Initially, Dr. Garlanger also assumed that the ditch and berm system would likewise not release any base flow. This is an unrealistic scenario because, as noted above, one of the two purposes of the ditch and berm system is to permit base flow into wetlands and streams. Later, Dr. Garlanger alternatively assumed that the ditch and berm system would release all of the base flow. If the ditch and berm system is equipped with recharge wells, it is reasonable to expect that the system will release all of the base flow. Calculating that the Horse Creek sub-basin upstream of State Road 64 is 39.5 square miles, Dr. Garlanger divided the average streamflow of 29.1 cfs at State Road 64 by the area of the sub-basin and determined that each square mile contributed 0.74 cfs of streamflow. Multiplying this number by the 5.4 miles captured by the ditch and berm system, Dr. Garlanger determined that, during mining, the ditch and berm system would reduce streamflow by 4 cfs, if it removed all base flow (and runoff). This very worst-case scenario would generate the following reductions in streamflow: in Horse Creek at State Road 72, 2.3 percent; in the Peace River at Ft. Ogden, 0.3 percent; and in the Peace River at Charlotte Harbor, 0.2 percent. Dr. Garlanger then calculated the reduction in streamflow in the probable scenario in which the ditch and berm system, with recharge wells, operates properly and releases the base flow, while still retaining all the runoff. Relying principally upon Mr. Lewelling's report on groundwater outflow in various locations within the Horse Creek sub-basin, Dr. Garlanger calculated that the capture rate would decrease from 0.74 cfs per square mile to 0.28 cfs per square mile. Applying a capture rate of 0.28 cfs per square mile times 5.4 miles, the reduction in streamflow, during mining, is more realistically 1.5 cfs. This means that, under the simplified analytic model, the ditch and berm system would reduce streamflow in Horse Creek at State Road 72 by less than one percent, in the Peace River at Ft. Ogden by .13 percent, and in the Peace River at Charlotte Harbor by .09 percent. These figures would represent the same reduction in streamflow caused by a decrease in average annual rainfall of 0.01 inches. Although, as discussed below, Dr. Garlanger also undertook more sophisticated modeling of streamflow during mining, this is a good point at which to address three of Mr. Davis's objections to Dr. Garlanger's during-mining analysis because these objections are more conceptual in nature and are not directed to Dr. Garlanger's model. Mr. Davis contended that the unmined wetlands would become dehydrated because: 1) the ditch and berm system would deprive them of surface flow or runoff from the areas behind the ditch and berm system; 2) the ditch and berm system would deprive them of adequate base flow or groundwater; and 3) water in the ditch would be lost to evapotranspiration. These objections are more applicable to a ditch and berm system without recharge wells. If the only source of water to rehydrate the wetlands is the groundwater running into the mine and rainfall directly on the area behind the berm, the loss of runoff into the area behind the berm and the loss of water to increased evaporation would require additional analysis to assure that adequate water remained to recharge the downstream wetlands through groundwater inputs. However, the recharge wells add additional water, probably from the deeper aquifers, so that adequate water can be supplied the downstream wetlands through groundwater inputs. To the extent that intercepted surface flow reduces water levels in the unmined wetlands, IMC can offset this loss by pumping more water into the ditch and increasing groundwater inputs into these wetlands. Mr. Davis's additional objection about additional evapotranspiration from the riparian wetlands assumes the condition that he claims will not occur--adequate hydration of the riparian wetlands--so it is impossible to credit this concern. Dr. Garlanger next analyzed streamflow by applying a simulation model. More sophisticated than the analytic model discussed in the preceding paragraphs, the uplands portion of this modeling also aided Dr. Garlanger's analysis of the hydroperiods and inundation depths of the wetlands in the no- mine area and the reclaimed wetlands, which are discussed in the next subsection. Dr. Garlanger's simulation model calculates site-specific groundwater outflows based on day-to-day hydrological conditions. Unlike the analytic model, which examined the effect on streamflow only during mining, the simulation model determines streamflow contributions from OFG without any mining disturbance for a 25-year period into the future, during mining, and after reclamation for the same 25- year period used in the no-mining analysis. The modeling proceeded in two stages. First, Dr. Garlanger modeled uplands. Then, inserting the groundwater and runoff outputs from the uplands model into a streamflow model, Dr. Garlanger modeled the riparian system to determine its contributions to streamflow at a point just downstream of OFG. Thus, rainfall is the only addition of water into the uplands system, but rainfall, groundwater outflow from the uplands into the riparian wetlands, and runoff from the uplands into the riparian wetlands are the additions of water into the riparian system. The uplands model is the Hydrological Evaluation of Landfill Performance (HELP) model. Developed for use in analyzing groundwater movement in landfills, HELP generally calculates groundwater outflow based on the hydraulic conductivity of the surficial aquifer divided by the square of the distance from the riparian wetland to the basin divide. In 2001, Dr. Garlanger modified the HELP model (HELPm). The modification multiplies the output from HELP by the square of the maximum height of the water table above the confining layer at the basin divide minus the square of the minimum height of the water table above the confining layer at the riparian wetlands. The only variable in HELPm is the maximum height of the water table above the confining layer; all other values, including those set forth above for HELP, are fixed. The modification improved the HELP model by allowing Dr. Garlanger, among other things, to reduce the extent to which the model is constrained by enabling him to input more realistic hydraulic conductivities. Using HELP, unmodified, Dr. Garlanger had had to input unrealistically high values for hydraulic conductivity. Hydraulic conductivity is either measured in the field or assumed. To simulate OFG without any mining for 25 years into the future, Dr. Garlanger had to obtain an input for hydraulic conductivity. Based on collected data from near the Panhandle as to daily fluctuations in the water table over a two-year period and sub-surface soil composition, as well as other information, Dr. Garlanger determined an average weighted hydraulic conductivity for OFG, pre-mining, of 19 feet per day with a low of 10 feet per day. Dr. Garlanger settled on an initial average weighted hydraulic conductivity of 15 feet per day for the surficial aquifer, but also identified a low-end average of 10 feet per day. As noted above, the contribution of an area of land to streamflow is dependent upon rainfall, evapotranspiration, deep recharge, and the change in storage, which is driven by the elevation of the water table (i.e., the top of the surficial aquifer) as it changes from day to day. Focusing on the vertical components of the water budget, HELPm calculates daily changes in storage, based on water table levels, so as to permit projections of runoff and groundwater outflow from the uplands. For rainfall, Dr. Garlanger relied upon the records of the Wauchula gauge, which is about 10 miles northeast from OFG. Rainfall data for this gauge go back to 1933, although to supplement some missing months, Dr. Garlanger relied on the Ft. Green gauge, which is closer to OFG, but does not go as far back as the Wauchula gauge. To supplement this information on the volume of rainfall, Dr. Garlanger added inputs on the frequency and rate of rainfall. For this calculation, Dr. Garlanger only used rainfall data for the period from 1978 to 2002 because the U.S. Geologic Service has collected streamflow data for Horse Creek at State Road 64 only as far back as 1978. Similar streamflow data for Horse Creek downstream at State Road 72 and for the Peace River go further back. Dr. Garlanger selected this timeframe so he could compare the model output of predicted streamflow to actual streamflow. HELPm calculates evapotranspiration, typically the largest source of water loss, on a daily basis. Dr. Garlanger calibrated evapotranspiration in his simulation by comparing HELPm calculations against average annual values for evapotranspiration for riparian wetlands, uplands, and wetlands in uplands, so as to permit the calculation of an average value of evapotranspiration for the Horse Creek basin above State Road Calibration is the process by which a hydrologist modifies the data inputs to the model based on measured data in order to produce a better match between observed and predicted data. Using generally accepted evapotranspiration values and the standard water-budget formula, Dr. Garlanger calculated average annual evapotranspiration for the Horse Creek basin above State Road 64 of 40.3 inches. He determined the following annual average evapotranspiration rates: riparian wetlands-- 47.5 inches; depressional wetlands--44 inches; seepage wetlands- -47.5 inches; well-drained uplands--34.5 inches; and other uplands--39 inches. Using this information, Dr. Garlanger then found the appropriate average annual evapotranspiration for the OFG uplands that he was modeling, and he reran the model five or six times until it produced outputs for uplands evapotranspiration consistent with this value. For uplands runoff, Dr. Garlanger turned to a well- recognized methodology for estimating the storage available in the uppermost foot of soil, as infiltration is an important factor in determining runoff. For groundwater outflow, Dr. Garlanger uses the one available equation, which is derived from Darcy's Law. Dr. Garlanger then ran his model for the no-mining, during-mining, and after-reclamation options, and he validated the model. In validation, the hydrologist confirms the model's outputs to measured data. In these exercises, Dr. Garlanger compared the predicted groundwater outflows with the empirical values published by Mr. Lewelling and predicted groundwater levels with those measured by IMC near the Panhandle. Dr. Garlanger ran the model with hydraulic conductivities of 10-15 feet per day and drainage times of 5-12 days. He eventually settled on an average hydraulic conductivity of 10 feet per day and an average drainage time of 12 days. Using these values, Dr. Garlanger validated his output by projecting streamflow from the entire 39.5-square mile area upstream of State Road 64, for which data exist. He found that the model produced a reasonable prediction of the flow duration curve. Dr. Garlanger then validated the output by comparing predicted and measured cumulative streamflow from 1978 through 1987, during which time mining in the Horse Creek basin was insignificant. He found a very good matchup between actual data and his model's predictions. Validating the output for average daily and average annual streamflow against actual data, Dr. Garlanger again found that the model performed acceptably. Dr. Garlanger then was prepared to model the 5.4 square-mile area for impact on Horse Creek streamflow at State Road 64 for 25 years without mining, during mining, and for 25 years after reclamation. For during-mining conditions, Dr. Garlanger assumed that the ditch and berm system would capture all of the runoff and none of the groundwater. For post-reclamation conditions, Dr. Garlanger assumed that the cast overburden spoil piles would be parallel to the flow of groundwater or, where that is not practicable, that the top of the spoil piles would be shaved by progressive amounts, ranging from five feet at the groundwater (or basin) divide progressively to 15 feet at the riparian wetland. This is vital to his calculations because of the vast difference in hydraulic conductivity of cast overburden spoil piles as compared to sand tailings. When oriented perpendicular to groundwater flow and unshaved, these spoil piles would act as underground dams, blocking the flow of groundwater. Dr. Garlanger modeled streamflow, in Horse Creek at State Road 64, which is just downstream of the confluence of Horse Creek and West Fork Horse Creek, under two scenarios: hydraulic conductivity of ten feet per day and drainage time of 12 days and hydraulic conductivity of fifteen feet per day and drainage time of five days. For post-reclamation hydraulic conductivity, Dr. Garlanger used 12 feet per day. With the higher streamflow reductions resulting from the lower hydraulic conductivities, Dr. Garlanger projected streamflow reductions, during mining, from 1.07-2.41 cfs and, after reclamation, from 0.10-0.14 cfs. These are average annual values. Generating a flow duration curve for Horse Creek at State Road 64 and using the more adverse data from the lower hydraulic conductivity value, Dr. Garlanger found a slight decrease, during mining, in flow during low-flow conditions, reflecting the mining of the Panhandle tributaries that contributed to groundwater outflow. Generating a stage duration curve, to depict the elevation of the water in the stream during the low-flow condition, Dr. Garlanger demonstrated that the difference is about three inches. After reclamation, as compared to pre-mining conditions, Dr. Garlanger determined that the average flow is decreased by 0.1 cfs, probably due to increased evapotranspiration from the additional reclaimed wetlands. This generates no discernible difference in the two flow duration curves for Horse Creek at State Road 64. Dr. Garlanger thus reasonably concluded that mining would not adversely affect the flow of Horse Creek at State Road 64 or dehydrate wetlands in the no-mine area. He concluded that, after reclamation, the impact would be de minimis as a decrease of 0.1 cfs is beyond the ability to measure flows. Farther downstream, at State Road 72, which is downstream of the confluence of Brushy Creek and Horse Creek, Dr. Garlanger calculated projected streamflow reductions, during mining, from 1.2-2.8 cfs and, after reclamation, from 0.12-0.16 cfs, which are too small to measure. Likewise, there are no discernible differences in the flow duration curves at State Road 72. Downstream of the confluence of Horse Creek and the Peace River, at Ft. Ogden, Dr. Garlanger calculated that the reduction in streamflow caused by mining at OFG would be equivalent to the reduction caused by a decrease of 0.01 inches of rainfall in the Peace River basin. Mr. Davis voiced many objections to Dr. Garlanger's streamflow calculations based on his reliance on HELPm. These objections are addressed at the end of the next section. Mr. Davis also voiced objections to Dr. Garlanger's calculations based on his understatement of the impact of phosphate mining on streamflow. As already noted, Dr. Garlanger made the better case on this issue. Distinguishing between the two rainfall eras in the Peace River basin--1933-1962 and 1969-1998--Dr. Garlanger reported that the measured average streamflow of the Peace River in the latter era was about 4.33 inches lower than the average streamflow of the Peace River in the former era. Finding that decreased average rainfall reduced streamflow by 3.75 inches per year, Dr. Garlanger calculates that the remaining 0.58 inches per year reduction in streamflow was largely due to an increase in deep recharge from 3.37 inches annually in the earlier era to 6.3 inches annually in the latter era. Anthropogenic changes in the Peace River basin have had opposing effects on streamflow. Urbanization, which causes increases in impervious surface, have increased runoff at the expense of evapotranspiration, thus increasing streamflow-- although certain demands of urbanization, such as groundwater pumping for potable water and industrial uses, will increase deep recharge, thus decreasing streamflow. Groundwater withdrawals by agriculture, industrial, utilities, and phosphate mining, net of the returns of these waters, have increased deep recharge, which, as just noted, decreases streamflow. Historically, phosphate mining's profligate use of deep groundwater also released much of the water back to streamflow, although the industry's historic predilection for Land-and-Lakes reclamation increased evapotranspiration and thus reduced streamflow. Converting inches of streamflow to cfs, Dr. Garlanger makes a good case that the streamflow of the Peace River is down about 500 cfs, mostly due to reduced rainfall amounts. About 50 cfs of that reduction is due to anthropogenic effects, and 5-15 cfs of man-caused reductions in the streamflow of the Peace River are due to phosphate mining. By contrast, Mr. Davis unconvincingly attributed a three-inch reduction in streamflow at the South Prong Alafia River to phosphate mining. This reduction in streamflow may be explained by Mr. Davis's failure to apply a lower and more reasonable streamflow assumption, absent mining; a lower and more likely rainfall amount; and a higher and more likely evapotranspiration rate. Wetland Hydroperiods and Inundation Depths 694. In making his groundwater calculations, Dr. Garlanger attempted to predict the behavior of the surficial aquifer, post-reclamation, and the ability of runoff and the water table to support the hydroperiods and inundation depths of the wetlands in the no-mine area and reclaimed wetlands. For this phase of his hydrological work, Dr. Garlanger again used the HELPm for the uplands and a long-term simulation model for the depressional wetlands in the uplands. The long-term simulation model is very similar to the streamflow model used for the riparian-wetland component of the streamflow modeling. Notwithstanding the replacement of the present geology with its more limited vertical permeability with wide bands of sand tailings down to the clay confining layer, Dr. Garlanger believes that deep recharge will remain unchanged by mining and reclamation because groundwater levels will return to their pre-mining elevations. To analyze the ability of the post-reclamation water table to support the reclaimed wetlands, Dr. Garlanger took 12 wetland cross-sections and projected fluctuations in water table and hydroperiod. These are presumably the 13 wetland complexes identified in Figure 13-3, described above. Dr. Garlanger testified about one modeled reclaimed wetland in detail--a freshwater marsh fringed by a wet prairie. This is E046/E047, which is a combined 16.1-acre wetland that is upgradient from E048, which is six-acre mixed wetland hardwoods that will replace the east half of a bay swamp (G166) and mixed wetland hardwoods fringes (G166B and G166C). Dr. Garlanger performs an iterative process based on a post-reclamation topographic map that starts with substantially pre-mining topography. Identifying the HELPm inputs, Dr. Garlanger takes the length of the upland to the riparian system and the assumed hydraulic conductivity based on the relative depths of sand tailings and cast overburden, and he then runs HELPm to determine the daily upland runoff and groundwater outflow. Dr. Garlanger then calculates the maximum height of the water table above the confining layer at any point downgradient from the basin divide to the riparian wetland. To input hydraulic conductivity, Dr. Garlanger testified that he obtains a value "based on the spoil piles and the depth that the spoil pile will be cut down to adjacent to the preserved area." (Tr, p. 2993) Applying the output to a wetlands model that is similar to the streamflow model, Dr. Garlanger then engages in an iterative process in which he adjusts and readjusts the post- reclamation topography to produce the proper elevation of the bottom of each modeled wetland for the hydroperiod that is stipulated for the vegetative community to be created in that location. Besides changing the bottom slope of each seepage wetland, the major adjustments for each wetland are narrowing its outlet or lowering its bottom elevation to extend its hydroperiod and deepen its inundation depth or broadening its outlet or raising its bottom elevation to shorten its hydroperiod and make its bottom elevation more shallow. Dr. Garlanger modeled the iterative process by continuing it late into the hearing, as he and IMC surveyor, Ted Smith, produced a "final" post-reclamation topographic map at the end of the hearing. Actually, even this map is not final, as Dr. Garlanger testified that he and Mr. Smith will produce the final topographic map, for wetlands, after the area is mined, photographed, backfilled, and graded, at which time they will know the location and direction of the cast overburden spoil piles. Dr. Garlanger will then use a calibrated model to account for actual in situ conditions. Due to the flatness of OFG, it is possible, even at this late stage, to regrade the sand tailings, if necessary for hydrological purposes. Monitoring wells will produce substantial data on the hydraulic conductivity of the no-mine area, as well as the hydroperiods of existing wetlands and the frequency with which seepage wetlands release water. Dr. Garlanger and IMC employees will also measure the hydraulic conductivity of the sand tailings and overburden in the reclaimed areas, also to assist their preparation of the final topographic map. As noted above, ERP Specific Condition 16.B.2 requires IMC to model 24 reclaimed wetlands to demonstrate successful water table re-creation and hydroperiod and inundation depth reclamation. Dr. Garlanger applied his models to confirm that, for each of the 24 modeled wetlands, the design topography and hydrology would produce the targeted hydroperiod and inundation depth. Mr. Davis modeled three reclaimed bay swamps. Bay swamps are the hardest wetlands for which to reclaim an appropriate water table due to their long hydroperiod, shallow inundation depths, and seepage characteristics. As noted above, no successful reclamation of bay swamps has ever taken place, except under circumstances inapplicable to OFG. The three reclaimed bay swamps are: E008, a 0.7-acre bay swamp abutting the west side of the Stream 1e series; E063, a 1.3-acre flow-through bay swamp in Stream 5e; and W039, an 11.2-acre bayhead from which Stream 1w will flow. W039 is a very large reclaimed wetland. After the 20.7-acre wet prairie (W003) to be reclaimed at the headwaters of Stream 9w and the 23.8-acre mixed wetland hardwoods (E003) lining the Stream 1e series, W039 is the largest reclaimed wetland at OFG, along with E018/E020, which are the isolated wet prairie fringe and freshwater marsh on the east side of Section 4. Mr. Davis testified as a witness in surrebuttal, which was necessitated by a late change by IMC in post- reclamation topography for these three bay swamps. Mr. Davis implied that he understood these three bay swamps better than he did the other reclaimed wetland systems. The fact is that he did understand these three reclaimed bay swamps better than he did any other reclaimed wetlands. Prior to testifying, at the order of the Administrative Law Judge, Mr. Davis and Dr. Garlanger conferred so that Mr. Davis, in preparing to respond to the "final" post-reclamation topography, would clarify any uncertainty about how Dr. Garlanger was modeling these wetlands and projecting their hydroperiods and inundation depths. Mr. Davis identified Dr. Garlanger's topographical changes to these three bay swamps. For E008, Dr. Garlanger lowered the west end of the wetland by 0.5 feet, extended a 114-foot contour up the channel, just east of an existing 115- foot contour, and possibly adjusted the slope. For E063, Dr. Garlanger lowered the bottom elevation by one foot, so that it can now store 0.3 feet of water, given its overflow popoff elevation. And for W039, Dr. Garlanger removed a slope and flattened the bottom, so that it can store 0.3 feet of water. From Dr. Garlanger's spreadsheets, Mr. Davis found the values for runoff, groundwater, and rainfall entering each wetland. Mr. Davis found that E008 received only 10 percent of its water from runoff, more of its water from rainfall, but most of its water from groundwater inflow. Noting that E008 abuts a reclaimed xeric area, Mr. Davis recalled a 6:1 ratio of groundwater inflow to runoff inflow. Mr. Davis explained that E008 loses most of its water to runoff. Mr. Davis found that the groundwater input for this wetland was consistent with the testimony of biologists, such as Deputy Director Cantrell, that bay swamps are primarily groundwater-driven systems, but questioned the absence of groundwater outflow to the adjacent, down-gradient riparian wetland (E003). For E063, however, Mr. Davis found that inputs from runoff, a more important source of water for this wetland, were about the same as inputs from groundwater. Although he did not testify to this fact, E063 is an unusual reclaimed bay swamp because it is the only one that will serve as a flow-through wetland, situated, as it is, in the middle of Stream 5e. This would seem to explain the larger role of surface water inputs than is typical of bay swamps adjacent to uplands. For W039, Mr. Davis found a small percentage of surface water and larger percentages of groundwater and rainfall as water sources for this wetland. Rainfall inputs would be greater due to the large area of the wetland, according to Mr. Davis. As a headwater wetland abutting uplands, W039 would be expected to have a higher input ratio, than E063, of water from groundwater versus runoff. Mr. Davis noted that W039 lost about half of its water to evapotranspiration, which would also make sense given its large surface area, and half to runoff, which would make sense given its status as a headwater wetland for Stream 1w. Mr. Davis then ran his MIKE SHE model to predict the hydroperiod for each wetland. This model is described in more detail at the end of this subsection. In simulating the hydrology of the reclaimed OFG, Mr. Davis assumed that the overburden spoil piles would be parallel to the direction of groundwater flow and eliminated any differential depressional storage, but he continued to assume two inches of depressional storage. (These assumptions are also discussed in connection with the MIKE SHE model.) Mr. Davis found that the 11.2-acre W039 will have a perfect hydroperiod. Its inundation hydroperiod will range from 8.6 months to 11.0 months, from bottom to top. Its saturation hydroperiod, which is water measured to a depth of 0.5 foot below the bottom of the wetland, will range from 8.8 months to 11.1 months, from bottom to top. Mr. Davis found that the 1.3-acre E063 will have a hydroperiod of 11.9 months, which is 0.9 months too long. Mr. Davis found that the 0.7-acre E008 will have a hydroperiod of 2.7 months for inundation and 4.6 months for saturation, which is about four months too short. 714. Crediting Mr. Davis's testimony, IMC's successful reclamation of an 11.2-acre bay swamp, dependent upon upland surface water and groundwater inputs, would be an unprecedented success. As discussed below, Mr. Davis's depressional assumption is not credited, so the hydroperiod of E063 would be shorter than the 11.9 months that he has calculated. Also, this reclaimed system will be a seepage system that would not permit the build-up of much standing water, so, even crediting Mr. Davis's calculations, Dr. Garlanger has achieved the proper hydrology for its reclamation too. It is more difficult to resolve the conflict in simulated hydroperiods for E008. E008 is a more complicated wetland to model because it is part of a reclaimed complex consisting of nine reclaimed wetlands. No other wetland complex to be reclaimed at OFG approaches this number of different communities in a single complex. Except for E018, which, although 30.7 acres, is a much simpler wetland system because it is an isolated complex of three wetlands, no other wetland complex to be reclaimed at OFG comes close to the area of the Stream 1e series' wetlands complex, which totals 35.1 acres, or over 10 percent of the wetlands to be reclaimed at OFG. Mr. Davis's unjustified depressional assumption generates excessively wet conditions, but, for E008, he found its hydroperiod to be too short by at least 3.4 months. And, of course, E008 is the difficult-to-reclaim bay swamp. The two models invite comparisons at this point. Mr. Davis's model, MIKE SHE, enjoys wide usage for calculating streamflows, hydroperiods, and inundation depths, as it has been used in these cases. MIKE SHE has been used successfully in large-scale settings. On the other hand, HELP was designed for calculating water levels in landfills. For calculating the uplands component of streamflow and hydroperiod, HELPm is used by Dr. Garlanger alone. The author of HELP's routine for lateral drainage and the subroutine for unsaturated vertical flow, Bruce McEnroe, pointed out that this model could accommodate only a regular, homogenous drainage layer, as would be found in a landfill, and could not accommodate the irregular, heterogeneous aquifer layer, which Dr. Garlanger was modeling. Mr. McEnroe also explained that the downstream boundary condition of HELP, which is free drainage, does not resemble the actual downstream boundary condition, in which groundwater cannot typically drain freely, and this limitation applies equally to the pre-mining and post-reclamation scenarios. Mr. McEnroe also found a mathematical error, but Dr. Garlanger later showed that it would alter results inconsequentially. Complaining about Dr. Garlanger's failure to provide comment lines in his source code, where he modified HELP, Mr. McEnroe emphasized that the model, as modified and used by Dr. Garlanger, really was no longer the HELP model. Counterposed to Mr. McEnroe's testimony was the testimony of Mark Ross, an associate professor of civil and environmental engineering at the University of South Florida College of Engineering. Professor Ross has 20 years' experience in hydrological modeling and has worked with the Florida Institute of Phosphate Research model that Mr. Davis helped develop, but which no longer is supported or in much use. Professor Ross conducted a peer review of the HELPm model, spending 20-30 hours in the process, exclusive of time spent discussing the model with Dr. Garlanger. Professor Ross endorsed Dr. Garlanger's use of a single value of .75 for evapotranspiration in riparian wetlands and his use of a weighted hydraulic conductivity. Professor Ross acknowledged that more complex models were available, but correctly opined that the simplest model was best if it could accommodate all of the available data. Although the emphasis in his testimony was on streamflow, Professor Ross addressed wetlands and their hydroperiods sufficiently to assure that his opinion of the sufficiency of the HELPm model covered both tasks. The interplay between the complexity of the model and availability of data emerged more clearly with the testimony of Authority hydrologist Henrik Sorensen, who developed code for the MIKE SHE model. Successful applications of this model range from the Danube River to Kuala Lampur to South Florida. The Danube River project was the construction of a dam, and hydrologists ran MIKE SHE to project the impact of the diverted streamflow on riparian wetlands. The Kuala Lampur project was the construction of a new city, and hydrologists ran MIKE SHE to project the impact of vastly changing land uses on the water level in the peat wetlands. South Florida projects have included a number of analyses of wetlands impacts of proposed activities. At Lake Tohopekaliga, hydrologists used MIKE SHE to project the effects on the water table and nearby wetlands of a 6-7 foot drawdown of the lake to remove muck. Unlike HELPm, MIKE SHE is an integrated model, meaning that all of its components are contained in a single model. Significant for present purposes, MIKE SHE integrates surface water and groundwater analysis in a single model, so as to facilitate the modeling of the interaction between a stream and surficial aquifer. This is especially important for simulating interactions between the surface and shallow water tables. MIKE SHE is a physically based model, meaning that it is based on equations derived from the laws of nature. In using HELPm and the spreadsheet models for streamflow and hydroperiod, Dr. Garlanger of course relies on laws of nature, but also relies on conceptualizations to link equation-driven outputs. As Mr. Sorensen explained, MIKE SHE is based on differential equations, so that it is dynamic as to time and space, but Dr. Garlanger's models are based on analytic equations, so they are limited to state-to-state solutions. The conceptualizations that link outputs and essentially integrate Dr. Garlanger's pairs of models are only as good as the conceptualizer, who, in the case of Dr. Garlanger, is very good, but conceptualizations can become so pervasive that the model loses its reliability and adds little or nothing to a conceptual exercise using an analytic model. Unlike MIKE SHE, HELPm is a lump-parameter model, which necessitates the input of average hydraulic conductivities, evapotranspiration rates, and leaf area indexes over relatively large areas and, in the case of evapotranspiration rates, sometimes at the expense of their calculation. Constraining a model, by inputting, rather than calculating, values to force results within an expected range, may resemble validation, but when the inputs become unrealistic, as Dr. Garlanger's hydraulic conductivity values were before he modified HELP, the model's credibility is impaired, not enhanced, by the process. Conceptualizations can eventually constrain modeled simulations so as to undermine confidence in the model's outputs. Unlike HELPm, MIKE SHE is spatially distributed, so that different land use types may be distributed throughout the model. HELPm may input different land uses for different basins, but MIKE SHE allows the user to input different land uses for different cells, each of the user's choice as to size. As noted by Mr. McEnroe, HELP was developed to simulate a shallow system running to a drain, and it remains well-suited for this task. In tracking the water table, HELPm assumes a constant thickness of the drainage layer, which reflects the design of landfills, not natural systems. As IMC contends, the post-reclamation geology will be far simpler than the pre-mining geology at OFG, but even the post-reclamation hydrology is far more complex than that of a landfill. With a 35:1 ratio of hydraulic conductivities, the surficial aquifer must negotiate the 330-foot wide valleys of sand tailings separated from 180-foot wide plateaus by 33-degree overburden slopes. Overburden peaks would have been simpler than overburden plateaus because the effective depth of sand tailings would have been at least five feet over nearly all of the mined area; as already noted, these overburden plateaus mean that, exclusive of shavings and toppings, overburden at less than five feet finished depth occupies about 28 percent of the surface of the mined area. This geology is much more complicated than the uniform geology of a landfill, especially when trying to project the surface water and groundwater inputs and outputs of shallow wetlands and streams, some of which will span several phases of this unusual geology. Unlike HELPm, MIKE SHE is used for its designed purpose when used for projecting streamflow and wetlands hydroperiods and inundation depths. It is widely used, peer- reviewed and supported with two or three updates annually. Mr. Sorensen made an interesting point when he opined that HELPm does a good job with average flows. This explains HELPm's reliability in calculating streamflows. Notwithstanding the calculation of peak discharge curves, accurate streamflow calculations--at least in this part of Florida--tolerate calculations based on average conditions and approximations much better than do accurate calculations of hydroperiod and inundation depths, especially concerning shallow wetlands in wetland complexes. MIKE SHE is not without its shortcomings, at least as applied in these cases. For his MIKE SHE simulation, Mr. Davis did not simulate first- and second-order streams, perched groundwater flow (i.e., interflow), or shallow concentrated overland flow, and, despite the model's sophistication, he still had to perform conceptualizations, such as of drainage. Mr. Davis's first two post-reclamation runs, prior to his final run of the three bay swamps, suffered from faulty assumptions. First, he assumed depressions and differential depressions based on a settling that Dr. Garlanger, with geotechnical engineering experience that Mr. Davis lacks, testified convincingly would not occur. Second, Mr. Davis assumed that the spoil piles would be oriented perpendicular to the direction of groundwater flow. Mr. Davis likely knew that IMC had agreed on December 23, 2003, to orient the mine cuts parallel to the direction of groundwater flow, to the extent practicable. Mr. Davis modeled the perpendicular scenario presumably due to the vagueness of the assurance, set forth only in the introduction to the January submittal, and thus unenforceable, that IMC would grade or shave the tops of overburden plateaus of spoil piles running perpendicular to groundflow. When performing his modeling, Mr. Davis could not have known of Dr. Garlanger's recommendation, as contained in a letter dated April 29, 2004--less than two weeks prior to the start of the final hearing--that IMC shave 5-15 feet off any perpendicular cast overburden spoil piles or that IMC would accept Dr. Garlanger's recommendation during the final hearing. As agreed to by IMC during the hearing, it will bulldoze any spoil piles oriented perpendicular to the direction of groundwater flow from 5-15 feet: the cut would allow five feet of sand tailings nearest the groundwater divide and would progressively deepen to allow 15 feet of sand tailings nearest the stream. For an average width of overburden of 195 feet with five feet thickness of sand tailings, which is the width calculated above under the less-favorable hydrological scenario with regard to the bases of the sand tailings valleys and cast overburden plateaus, Dr. Garlanger calculated a hydraulic conductivity of seven feet per day. Mr. Davis assumed that IMC would not be able to orient the spoil piles parallel to groundwater flow, but nothing indicates that the proper orientation of these piles will be impracticable over significant areas of land. If a turn of the dragline near Horse Creek leaves a relatively short area of spoil perpendicular to groundwater flow and if IMC will shave this area as it does rows, shaving the pile down 15 feet would substantially improve water table/shallow wetland interaction over the portion of the mined area that is left with an overburden plateau. Conceptualizing the contingency of a spoil pile blocking groundwater flow close to Horse Creek, such as from the U-turn of the dragline at the end of a row, the bulldozing of that spoil pile down to an effective 15-foot depth would leave a depth of at least 15 feet of sand tailings running 1095 feet, as measured alongside of Horse Creek out to a point at which the spoil piles would again run parallel to groundwater flow. If all of the spoil piles turned at Horse Creek and assuming that IMC will cut down the cast overburden piled against the sides of the mine cuts, for the distance equal to the distance between the edge of the no-mine area to the start of the curve, sand tailings would be at least 15 feet deep. The real problem with MIKE SHE, as applied at OFG, is its sophistication. Mr. Sorensen admitted that he had not reviewed the data available for this part of Florida, but claimed that he knew, based on his work in South Florida, that sufficient data existed to run the MIKE SHE model. This is highly unlikely. In addition to Mr. Davis's observation about the lack of data, the record reveals a slimmer universe of data than Mr. Sorensen imagined to exist. Measured values for the hydraulic conductivity of pre-mined or post-reclaimed areas are largely unavailable. For specific reclamation sites, little data exist of pre-mining and post-reclamation soil textures, water tables, and wetland hydroperiods and stage elevations. By volume, the two most critical inputs are rainfall and evapotranspiration, which must be calculated or assumed because, for practical purposes, it cannot be directly measured. A major determinant of evapotranspiration is the water table elevation. The critical inputs of rainfall and water table elevations illustrate the shortcomings of the data for these cases. Rainfall records in the general area cover a long period of time, except that collection points are usually far enough away from the site to be analyzed as to raise the probability of significant daily fluctuations, which average out over time. MIKE SHE inputs rainfall spatially and hourly while HELPm inputs a single daily value. Without regard to any particular application, MIKE SHE is the superior model on this point, but its superiority is wasted when the data of hourly rainfall for individual cells are unavailable and values, often based on much longer intervals at much greater distances, must be interpolated. Records for most surficial aquifer monitoring wells in the area date back only to the early 1990s and are fairly spotty as to locations. MIKE SHE inputs spatially distributed groundwater elevations, while HELPm inputs a single value. If, as Mr. Davis testified, multiple inputs of water table elevations, for which direct OFG data are unavailable, must rely on a hydrologist's knowledge of surficial aquifer responses, MIKE SHE would share the same tendency of HELPm--at least for this variable--of relying on external guidance to produce its output. By contrast, the scientists studying the Danube River had lacked the resources for many years to do much more than collect data, so the data for the Danube MIKE SHE simulation was much richer than the data available at OFG. In such data-rich environments, MIKE SHE is the superior model for wetland hydroperiods and inundation depths. The question in these cases is whether, given the limitations of the OFG data and HELPm in simulating hydroperiods and inundation depths, IMC has still provided reasonable assurance of the reclamation of functional hydroperiods and inundation depths for reclaimed wetlands. IMC's case as to reclaimed hydroperiods and inundation depths is undermined by certain aspects of the use of HELPm in these cases. The scientific method, which lends confidence to analysis-driven conclusions to the extent that others can reproduce the analytic process, is poorly served by computer code that is modified without notation and modeling results that no one can reproduce due to the repeated intervention of the modeler, applying his touch and feel to the simulation. Only at the end of nearly eight weeks of hearing and a conference between Dr. Garlanger and Mr. Davis could Mr. Davis finally gain sufficient understanding of Dr. Garlanger's modeling process to make a meaningful comparison between his conclusions and Dr. Garlanger's conclusions for the hydroperiods and inundation depths of three wetlands. When applied to project streamflow, with its relative amenability to average inputs, and when applied to projecting the hydroperiods and inundation depths of deeper and more isolated wetlands, HELPm, as used by Dr. Garlanger, who, as an experienced and highly competent hydrologist, can adjust and re- adjust inputs and outputs, produces reasonable assurance. However, Mr. Davis's analysis of Dr. Garlanger's work and other factors preclude a finding that Dr. Garlanger has provided reasonable assurance that IMC will reclaim a functional hydroperiod and inundation depths for E008. The finding in the preceding paragraph implies no similar rejection of Dr. Garlanger's modeling of the other wetlands. Most of the modeled reclaimed wetlands are isolated and do not present the challenge of simulating complex interactions among them, where an error in modeling an upgradient wetland will cause an error in modeling a downgradient wetland. A couple of the modeled reclaimed wetlands are headwater wetlands, which Dr. Garlanger has demonstrated his ability to model in W039. Outside of the Stream 1e series, the only wetlands similar in location to E008, as attached to a riparian system, will be E040, E048, E054 complex, and W044, of which only E048 is to be modeled. Mr. Davis also addressed E048 in surrebuttal. A wetland forested mixed, E048 will replace a high-functioning bay swamp abutting, or a part of, the riparian wetlands of Horse Creek. Mr. Davis admitted that he could agree with Dr. Garlanger's analysis of inputs into E048 from isolated reclaimed wetlands upgradient of E048, so that he could agree with Dr. Garlanger's projected hydroperiod for this reclaimed wetland. However, Mr. Davis explained that E008 is located in the flatter Panhandle, but that E048, as well as the other reclaimed wetlands listed in the preceding paragraph, are located in areas characterized by steeper grades and more xeric conditions, which support Dr. Garlanger's emphasis on groundwater inputs over surface water inputs. Peak Discharges During mining, the ditch and berm system prevents adverse flooding. If it operates as intended, the ditch and berm system delays the release of runoff from OFG by re-routing it through one of the NPDES outfalls. This decreases peak discharge downstream of OFG. Presumably, IMC will operate the recharge wells in anticipation of storm events--allowing the water levels to lower in advance of storms and maintaining higher water levels in advance of drier periods--so as not to raise the possibility of flooding by way of accelerated discharges through the NPDES outfalls. Failure of the ditch and berm system is highly improbable. The sole failure reported in this record did not involve a system as engineered as the one proposed for OFG, according to Dr. Garlanger. Another possible source of flooding during mining arises from the designed blockage of flow from unmined areas. IMC plans a single, elevated pipeline crossing across Stream 2e, and Dr. Garlanger explained that the design of the culvert, as part of this temporary crossing, will not result in adverse flooding during mining. Similar design work by Dr. Garlanger will be necessitated, if DEP issues a Final Order incorporating the recommendation below that the Stream 1e series and its 25-year floodplain also be placed in the no-mine area. The riparian wetlands for the Stream 1e series are narrowest along Stream 1ee, so this may be the location that DEP determines for the dragline walkpath corridor, if DEP determines that IMC may maintain a dragline crossing anywhere along the Stream 1e series. The sole issue, during mining, involving peak discharges is a legal question, which is whether IMC's ditch and berm system has the capacity to accommodate the design storm. As noted below, the design storm is the 25-year storm, if the ditch and berm system is an open drainage system, and the design storm is the 100-year storm, if the ditch and berm system is a closed drainage system. The capacity of the proposed ditch and berm system is designed to accommodate the 25-year storm, but not the 100-year storm. The facts necessary to determine if the ditch and berm system is open or closed are set forth above. In its Final Order, DEP must characterize a system that is closed in the sense of the availability of a passive discharge outfall, but open in the sense that, with the intervention of pumps--assuming the availability of electricity during a major storm or alternative sources of power--excessive volumes of water may be moved to an NPDES outfall. This is a minor issue because, even if DEP determines that the ditch and berm is a closed system, IMC may easily heighten the berm as necessary to accommodate the 100-year storm. Post-reclamation, many of the changes that IMC will make to OFG will reduce peak discharges. The agricultural alterations that ditched and drained wetlands accelerated drainage and increased peak discharges downstream, as compared to pre-existing natural drainage rates and peak discharge volumes. The removal of these ditches, the net addition of 24 acres of forested wetlands and 48 acres of herbaceous wetlands, the addition of sinuosity and in-stream structure to the reclaimed streams, and the redesigning of the banks of the reclaimed streams so as to permit communication between the reclaimed streams and their floodplains will attenuate floodwaters, slow the rate of runoff, increase temporary storage, and ultimately reduce peak discharges from their present values. Dr. Garlanger modeled peak discharges using the Channel Hydrologic Analysis Networking (CHAN) model, which is a widely accepted model to simulate peak discharges. As already noted, Mr. Loper found several inconsistencies and flaws in earlier modeling, but Dr. Garlanger, undeterred, re-ran the CHAN simulations, incorporating Mr. Loper's findings, as Dr. Garlanger deemed necessary. The bottom line is that, post-reclamation, very small increases in peak discharges will occur at the Carlton cutout and would occur at some property immediately downstream of the point at which Horse Creek leaves OFG. The owners of the Carlton cutout consented to the very minor flooding of their pasture land, and IMC, of course, has no objection to the very minor flooding of its downstream property. Even absent these consents, the very limited extent and frequency of flooding, given the prevailing agricultural uses in the area, could not be characterized as adverse. Among the points raised by Mr. Loper was the absence of mapping of any floodplain besides the 100-year floodplain of Horse Creek. The omission of other floodplains is of environmental or biological importance, but not direct hydrological importance. If for no other reason than that IMC will replicate pre-mining topography, especially at the lower elevations, there will be no loss of floodplain storage. 4. Water Quality Water quality violations characterize past efforts to reclaim streams, other than Dogleg Branch, but the good water quality at Dogleg Branch means that the phosphate mining industry can reclaim streams and maintain water quality, post- reclamation. The intensive engineering in IMC's Stream Restoration Plan raises the prospect of successfully reclaimed water quality, especially among the simpler, more altered stream systems to be reclaimed. There is little doubt that, during mining, few impacts to water quality take place. The ditch and berm systems in place during the upstream mining in the Horse Creek sub-basin have permitted no degradation of water quality. Given the present condition of most of the tributaries and extensive agricultural alterations of most of OFG, successful reclamation may be expected to result in certain changes to water quality, among already-altered tributaries, at least once the reclaimed communities have established themselves. Successful reclamation of these streams and their channels should lower turbidity, by replacing their incised, unstable stream channels and banks with stable channels and banks. The addition of riffles and structure to the stream bed should raise dissolved oxygen levels in these streams. Excluding cattle from these streams, by placing cattle ponds away from Horse Creek and vegetatively screening Horse Creek and the tributaries, should lower adverse impacts, such as turbidity, due to cattle damage to the banks, and nutrient loading, due to cattle waste discharges. Phosphorus is sometimes temporarily higher after mining, but this may be merely a trophic surge. Water temperature will cool with the addition of forested riparian wetlands, once the canopy develops, where none presently exists. However, none of these effects can be anticipated with the reclamation of the relatively pristine Stream 1e series. Other reclamation activities may also be anticipated to improve water quality. These activities include adding net wetlands area, replacing low-functioning wetlands with wetlands with the potential to achieve high-functioning levels, concentrating wetlands more around streams, adding supportive uplands, and otherwise increasing storage and slowing runoff. These activities will raise the level of natural filtration, compared to the natural filtration presently performed at OFG. Wildlife Management and Habitat The wildlife management plans are reasonable accommodations of wildlife that presently use OFG, based on the frequency of the usage by each species and the degree of protection afforded certain species. It is important that IMC update wildlife utilization information for the period that elapses between the site visits and the commencement of mining; wildlife usage by some species, especially the Audubon crested caracara, was discovered shortly before the hearing and, if later found to be more intense, will require more intensive wildlife management plans. Likewise, DEP will need confirmation of FWC's approval of IMC's gopher tortoise relocation plan. Always of especial concern is the Florida panther. Obviously, the accommodations necessary for one or two male Florida panthers visiting OFG are far less intensive than those necessary if a breeding pair had established themselves at the site. Ms. Keenan testified that the ERP/CRP approval should have incorporated the entire Habitat Management Plan. Although the ERP and CRP approval would be strengthened by the incorporation of the Habitat Management Plan, and DEP may elect to do so in its Final Order, the provisions actually incorporated adequately address wildlife management concerns. The evidence fails to establish that OFG, which has been logged over the years, presently supports red cockaded woodpeckers. Clearly, as is the case with the Audubon's crested caracara, IMC is committed to develop, prior to mining, appropriate management plans that meet the needs of whatever species are found using OFG between the hearing and the start of mining. In general, the reclamation of OFG will improve the value of the area for wildlife habitat. The concentration of reclaimed wetlands reduces induced edge by 36 miles. Induced edges artificially increase predation and decrease the function of the upland/wetland interface for those aquatic- or wetland- dependent species that rely on adjacent uplands during parts of their life cycle. The increased breadth of the riparian wetlands, which has been detailed above, also improves wildlife utilization and habitat values by discourage cattle from using the streams and adjacent wetlands. IMC's reclamation plan slightly increases the area of cattle ponds and locates them farther away from sensitive wetlands and streams. IMC's reclamation plan also serves the often- overlooked needs of amphibians. The creation of isolated and ephemeral wetlands, which will not receive floodwaters from Horse Creek or its tributaries in most storm events, will enable these amphibians to develop sustainable populations and flourish. At present, two factors have led to artificially high levels of predation of these amphibians by small fish. Ditching of formerly isolated wetlands and the proximity of still- isolated wetlands to tributaries and their connected wetlands-- so as to allow runoff to connect the two systems during storm events--allow small fish to enter the habitat of the amphibians and prey upon them at artificially high rates. Mitigation/Reclamation--Financial Responsibility IMC has never defaulted on any of its reclamation or mitigation responsibilities. Its mitigation cost estimates are ample to cover the listed expenses of the proposed wetlands mitigation, with two exceptions. For reasons set forth in the Conclusions of Law, IMC is not required to post financial security at this time for any CRP reclamation, such as the reclamation of uplands not relied upon by aquatic- and wetlands- dependent species, that is not also ERP mitigation. However, the listed expenses omit two important items of ERP mitigation. First, the listed expenses omit Dr. Garlanger's fees for final engineering work on wetlands hydroperiods and inundation depths after backfilling has been completed. This is an expense covered under reclamation, as well as mitigation, pursuant to Chapter 378, Part III, and Chapter 373, Part IV, Florida Statutes, respectively. Second, the listed expenses omit the cost of acquiring sand tailings, transporting them to the mine cut, and contouring them. For the reasons discussed in the Conclusions of Law, the cost of obtaining and transporting the sand tailings is not required under reclamation, pursuant to Chapter 378, Part III, Florida Statutes, but is required under mitigation under Chapter 373, Part IV, Florida Statutes. Charlotte County contends that the cost of obtaining, transporting, and contouring sand tailings is $35,588 per acre, according to Mr. Irwin. This represents $10,588 per acre, as Mr. Irwin's "best guesstimate" for earthmoving, which seems to include the stripping and preserving of the A and B horizons, and $25,000 per acre for the shaping of wetland reclamation units. This testimony includes items for which financial security is not required, such as preserving the A and B horizons, and excludes the third-party cost of acquiring sufficient sand tailings to backfill the OFG mine cuts to the post-reclamation topography and transporting these sand tailings to OFG. The record supplies no information on these costs.

The Issue The issue in this case is whether, and under what conditions, the Respondent, St. Johns River Water Management District (District), should grant Environmental Resource Permit (ERP) No. 40-109-81153-1 authorizing Respondents, Jay and Linda Ginn (Ginns or Applicants), to construct a 136-unit single-family residential development with associated surface water management system.
Findings Of Fact The Parties and Proposed Project Respondent, the District, is a special taxing district created by Chapter 373, Florida Statutes, charged with the duty to prevent harm to the water resources of the District, and to administer and enforce the cited statutes and Florida Administrative Code Rules promulgated by the District under the authority of those statutes. (Unless otherwise stated, all Florida Statutes refer to the 2003 codification, and all Florida Administrative Code Rules refer to the current codification.) Respondents, Jay and Linda Ginn, are the owners of 47 acres of land located just west of the City of St. Augustine in St. Johns County, Florida. They are seeking ERP Permit No. 40- 109-81153-1 from the District to construct a 136-acre residential community and associated surface water management facilities on the property, to be known as Ravenswood Forest. The 47-acre project site is predominantly uplands, with a large (10.98-acre) wetland (Wetland 1) located on the eastern boundary and completely separating the uplands on the project site from adjacent properties to the east. While the central portion of the site is mostly a sand pine vegetated community, and the western portion is largely a pine flatwood community, there are six other smaller wetlands scattered within the upland areas lying west of Wetland 1, each numbered separately, 2 through 7. The site is currently undeveloped except for some cleared areas that are used as dirt road trails and a borrow pit or pond excavated in the central part of the site. This clearing and excavation was accomplished in the 1980’s for a project that was never completed. The project site is bordered on the north by Ravenswood Drive. On the east lies an existing residential development probably constructed in the 1970’s; to the west of the project site is a power-line easement; and to the south is a Time Warner cable facility. The land elevations at the project site are generally higher on the west and slope off to Wetland 1 on the east. Under current conditions, water generally drains from west to east into Wetland 1. Some water from the site, as well as some water entering the site from off-site properties to the west, flows into the existing pond or borrow pit located in the central portion of the site. Under extreme rainfall conditions, the borrow pit/pond can reach a stage that allows it to overflow and discharge into Wetland 1. Some off-site water also enters Wetland 1 at its north end. Water that originates from properties to the west of the Ravenswood site is conveyed through ditches to the roadside ditch that runs along the south side of Ravenswood Drive. Water in this roadside ditch ultimately enters Wetland 1 at its north end and flows south. Once in Wetland 1, water moves north to south. Water leaves the part of Wetland 1 that is located on the Ravenswood site and continues to flow south through ditches and culverts ultimately to the San Sebastian River. The Wetland 1 system is contiguous with wetlands located on property owned by Petitioner, Marilyn McMulkin. Mrs. McMulkin lives on Hibiscus Street to the east of the project. Mrs. McMulkin is disabled and enjoys observing wildlife from her home. Mrs. McMulkin has observed woodstorks, kites, deer, cardinals, birds, otter, indigo snake, flying squirrels, gopher tortoises, and (more recently) bald eagles on her property or around the neighborhood. Mrs. McMulkin informed the District of the presence of the bald eagle in 2002, but it was not discovered until November of 2003 that there was an eagle nest on the Ginns property in Wetland 1. Petitioner, Diane Mills, owns a house and property on Hibiscus Street to the east of the Project. The proposed stormwater discharge for the Project is to a wetland system that is contiguous with a wetland system that is in close proximity to Mrs. Mills' property. Petitioners' property is not located in a flood plain identified by FEMA. Nevertheless, Petitioners' property experiences flooding. At times, the flooding has come through Mrs. McMulkin's house and exited out the front door. The flood water, which can be 18-24 inches high in some places on Mrs. McMulkin's property, comes across her backyard, goes through or around her house, enters Hibiscus Street and turns north. The flooding started in the late 1980's and comes from the north and west, from the Ginns' property. The flooding started after Mr. Clyatt Powell, a previous co-owner of the Ravenswood property, started clearing and creating fill roads on the property using dirt excavated from the property. The flooding now occurs every year and has increased in duration and frequency; the flooding gets worse after the rain stops and hours pass. The evidence, including Petitioners' Exhibit 1, indicated that there are numerous other possible reasons, besides activities on the Ginns' property in the late 1980's, for the onset and exacerbation of Petitioners' flooding problems, including: failure to properly maintain existing drainage facilities; other development in the area; and failure to improve drainage facilities as development proceeds. The parties have stipulated that Petitioners have standing to object to ERP Permit No. 40-109-81153-1. Project Description As indicated, water that originates west of the project site currently enters the project site in two ways: (1) it moves across the western project boundary; and (2) it travels north to a ditch located on the south side of Ravenswood Drive and is conveyed to Wetland 1. The offsite water that moves across the western project boundary comes from a 16-acre area identified as Basin C (called Basin 4 post-development). The offsite water that moves north to the ditch and enters Wetland 1 comes from a 106.87-acre area identified as Basin D (called Basin 5 post-development). The project’s stormwater conveyance and treatment facilities include two connected wet detention ponds with an outfall to a wetland on the eastern portion of the project site. Stormwater from most of the project site will be conveyed to a pond, or detention area (DA) DA-1, which will be located near (and partially coinciding with the location of) the existing pond or borrow pit. The water elevation in DA-1 will be controlled at a level of 26 feet. Water from DA-1 will spill over through a control structure into a pipe that will convey the spill-over to DA-2. In addition to the spill-over from DA-1, offsite water that currently enters the project site across the western boundary will be conveyed to a wetland area at the southwest corner of the project site. At that point, some of the water will be taken into DA-2 through an inlet structure. The water elevation in DA-2 will be controlled at level 21. Water from DA-2 will be released by a control structure to a spreader swale in Wetland 1. While some of the water conveyed to the wetland area at the southwest corner of the project site will enter DA-2, as described, some will discharge over an irregular weir (a low area that holds water until it stages up and flows out) and move around the southern boundary of the project site and flow east into Wetland 1. Wetland 1 is a 10.98-acre onsite portion of a larger offsite wetland area extending to the south and east (which includes the wetlands on Mrs. McMulkin's property). For purposes of an Overall Watershed Study performed by the Ginns' engineering consultant, the combined onsite and offsite wetlands was designated Node 98 (pre-development) and Node 99 (post- development). From those areas, water drains south to ditches and culverts and eventually to the San Sebastian River. Best management practices will be used during project construction to address erosion and sediment control. Such measures will include silt fences around the construction site, hay bales in ditches and inlets, and maintenance of construction equipment to prevent release of pollutants, and may include staked sod on banks and turbidity barriers, if needed. In addition, the District's TSR imposed permit conditions that require erosion and sediment control measures to be implemented. The District's TSR also imposed a permit condition that requires District approval of a dewatering plan within 30 days of permit issuance and prior to construction. The Ginns intend to retain the dewatering from construction on the project site. Wetland Impacts Onsite Wetlands Wetland 1 is a 10.98-acre mixed-forested wetland system. Its overall condition is good. It has a variety of vegetative strata, a mature canopy, dense understory and groundcover, open water areas, and permanent water of varying levels over the course of a year. These attributes allow for species diversity. Although surrounded by development, the wetland is a good source for a variety of species to forage, breed, nest, and roost. In terms of vegetation, the wetland is not unique to northeast Florida, but in November 2003 an eagle nest was discovered in it. A second wetland area onsite (Wetland 2) is a 0.29-acre coniferous depression located near the western boundary of the site. The overall value of the functions provided by Wetland 2 is minimal or low. It has a fairly sparse pine canopy and scattered ferns provide for little refuge and nesting. Water does stand in it, but not for extended periods of time, which does not allow for breeding of most amphibians. The vegetation and inundation do not foster lower trophic animals. For that reason, although the semi-open canopy would be conducive to use by woodstorks, birds and small mammals do not forage there. A third wetland area onsite (Wetland 3) is a 0.28-acre mixed-forested wetland on the northern portion of the site. The quality of Wetland 3 is low. A 24-inch culvert drains the area into a 600-foot long drainage ditch along the south side of Ravenswood Drive leading to Wetland 1. As a result, its hydroperiod is reduced and, although it has a healthy pine and cypress canopy, it also has invasive Chinese tallow and upland species, along with some maple. The mature canopy and its proximity to Ravenswood Drive would allow for nesting, but no use of the wetland by listed species has been observed. In order to return Wetland 3 to being productive, its hydroperiod would have to be restored by eliminating the connection to the Ravenswood Drive ditch. A fourth wetland area onsite (Wetland 4) is a 0.01- acre portion of a mixed-forested wetland on the western boundary of the site that extends offsite to the west. Its value is poor because: a power line easement runs through it; it has been used as a trail road, so it is void of vegetation; and it is such a small fringe of an offsite wetland that it does not provide much habitat value. A fifth wetland area onsite (Wetland 5) is a 0.01-acre portion of the same offsite mixed-forested wetland that Wetland 4 is part of. Wetland 5 has a cleared trail road through its upland fringe. Wetland 5 has moderate value. It is vegetated except on its upland side (although its vegetation is not unique to northeast Florida), has a nice canopy, and provides fish and wildlife value (although not as much as the interior of the offsite wetland). A sixth wetland area onsite (Wetland 6) is a 0.28-acre wetland located in the western portion of the site. It is a depression with a coniferous-dominated canopy with some bays and a sparse understory of ferns and cord grass that is of moderate value overall. It does not connect with any other wetlands by standing or flowing water and is not unique. It has water in it sufficient to allow breeding, so there would be foraging in it. Although not discovered by the Ginns' consultants initially, a great blue heron has been observed utilizing the wetland. No listed species have been observed using it. Wetland 6 could be good gopher frog habitat due to its isolation near uplands and its intermittent inundation, limiting predation by fish. In addition, four gopher tortoise burrows have been identified in uplands on the project site, and gopher frogs use gopher tortoise burrows. The gopher frog is not a listed species; the gopher tortoise is listed by the State of Florida as a species of special concern but is not aquatic or wetland-dependent. Woodstorks are listed as endangered. Although no woodstorks were observed using Wetland 6, they rely on isolated wetlands drying down to concentrate fish and prey in the isolated wetlands. With its semi-open canopy, Wetland 6 could be used by woodstorks, which have a wingspan similar to great blue herons, which were seen using Wetland 6. However, Wetland would not provide a significant food source for wading birds such as woodstorks. The other surface water area onsite (Wetland 7) is the existing 0.97-acre pond or borrow pit in the southwest portion of the project site. The pond is man-made with a narrow littoral shelf dominated by torpedo grass; levels appears to fluctuate as groundwater does; and it is not unique. It connects to Wetland 1 during seasonal high water. It has some fish, but the steep slope to its littoral shelf minimizes the shelf's value for fish, tadpoles, and larvae stage for amphibians because fish can forage easily on the shelf. The Ginns propose to fill Wetlands 2, 3, 4, and 6; to not impact Wetland 5; and to fill a 0.45-acre portion of Wetland and dredge the remaining part into DA-1. Also, 0.18 acre of Wetland 1 (0.03 acre is offsite) will be temporarily disturbed during installation of the utility lines to provide service to the project. Individually and cumulatively, the wetlands that are less than 0.5-acre--Wetlands 3, 6, 2, 4, and 5--are low quality and not more than minimal value to fish and wildlife except for Wetland 5, because it is a viable part of an offsite wetland with value. While the Ginns have sought a permit to fill Wetland 4, they actually do not intend to fill it. Instead, they will simply treat the wetland as filled for the purpose of avoiding a County requirement of providing a wetland buffer and setback, which would inhibit the development of three lots. Offsite Wetlands The proposed project would not be expected to have an impact on offsite wetlands. Neither DA-1 nor DA-2, especially with the special conditions imposed by the District, will draw down offsite wetlands. The seasonal high water (SHW) table in the area of DA- 1 is estimated at elevation 26 to 29. With a SHW table of 26, DA-1 will not influence groundwater. Even with a SHW table of 29, DA-1 will not influence the groundwater beyond the project's western boundary. DA-1 will not adversely affect offsite wetlands. A MODFLOW model was run to demonstrate the influence of DA-1 on nearby wetlands assuming that DA-1 would be controlled at elevation 21, that the groundwater elevation was 29, and that no cutoff wall or liner would be present. The model results demonstrated that the influence of DA-1 on groundwater would barely extend offsite. The current proposed elevation for DA-1 is 26, which is higher than the elevation used in the model and which would result in less influence on groundwater. The seasonal high water table in the area of DA-2 is 28.5 to 29.5. A cutoff wall is proposed to be installed around the western portion of DA-2 to prevent it from drawing down the water levels in the adjacent wetlands such that the wetlands would be adversely affected. The vertical cutoff wall will be constructed of clay and will extend from the land surface down to an existing horizontal layer of relatively impermeable soil called hardpan. The cutoff wall tied into the hardpan would act as a barrier to vertical and horizontal groundwater flow, essentially severing the flow. A MODFLOW model demonstrated that DA-2 with the cutoff wall will not draw down the adjacent wetlands. The blow counts shown on the boring logs and the permeability rates of soils at the proposed location of DA-2 indicate the presence of hardpan. The hardpan is present in the area of DA-2 at approximately 10 to 15 feet below the land surface. The thickness of the hardpan layer is at least 5 feet. The Ginns measured the permeability of hardpan in various locations on the project site. The cutoff wall design is based on tying into a hardpan layer with a permeability of 0.052 feet per day. Because permeability may vary across the project site, the District recommended a permit condition that would require a professional engineer to test for the presence and permeability of the hardpan along the length of the cutoff wall. If the hardpan is not continuous, or if its permeability is higher than 0.052 feet per day, then a liner will be required to be installed instead of a cutoff wall. The liner would be installed under the western third of DA-2, west of a north-south line connecting the easterly ends of the cutoff wall. (The location of the liner is indicated in yellow on Applicants' Exhibit 5B, sheet 8, and is described in District Exhibit 10.) The liner would be 2 feet thick and constructed of clay with a permeability of no more than 1 x 10-6 centimeters per second. A liner on a portion of the bottom of pond DA-2 will horizontally sever a portion of the pond bottom from the groundwater to negate the influence of DA-2 on groundwater in the area. A clay liner would function to prevent adverse drawdown impacts to adjacent wetlands. The project, with either a cutoff wall or a clay liner, will not result in a drawdown of the groundwater table such that adjacent wetlands would be adversely affected. Reduction and Elimination of Impacts The Ginns evaluated practicable design alternatives for eliminating the temporary impact to 0.18-acre of Wetland 1. The analysis indicated that routing the proposed utility services around the project site was possible but would require a lift station that would cost approximately $80,000 to $100,000. The impact avoided is a temporary impact; it is likely that the area to be impacted can be successfully reestablished and restored; and preservation of Wetland 1 is proposed to address lag-time for reestablishment. It was determined by the Ginns and District staff that the costs of avoidance outweigh the environmental benefits of avoidance. Petitioners put on evidence to question the validity of the Wetland 1 reduction/elimination analysis. First, Mr. Mills, who has experience installing sewer/water pipes, testified to his belief that a lift station would cost only approximately $50,000 to $60,000. He also pointed out that using a lift station and forced main method would make it approximately a third less expensive per linear foot to install the pipe line itself. This is because a gravity sewer, which would be required if a lift station and forced main is not used, must be laid at precise grades, making it is more difficult and costly to lay. However, Mr. Mills acknowledged that, due to the relatively narrow width of the right-of-way along Ravenswood Drive, it would be necessary to obtain a waiver of the usual requirement to separate the sewer and water lines by at least 10 feet. He thought that a five-foot separation waiver would be possible for his proposed alternative route if the "horizontal" separation was at least 18 inches. (It is not clear what Mr. Mills meant by "horizontal.") In addition, he did not analyze how the per-linear-foot cost savings from use of the lift station and forced main sewer would compare to the additional cost of the lift station, even if it is just $50,000 to $60,000, as he thinks. However, it would appear that his proposed alternative route is approximately three times as long as the route proposed by the Ginns, so that the total cost of laying the sewer pipeline itself would be approximately equal under either proposal. Mr. Mills's testimony also suggested that the Ginns did not account for the possible disturbance to the Ravenswood eagles if an emergency repair to the water/sewer is necessary during nesting season. While this is a possibility, it is speculative. There is no reason to think such emergency repairs will be necessary, at least during the approximately 20-year life expectancy of the water/sewer line. Practicable design modifications to avoid filling Wetland 4 also were evaluated. Not filling Wetland 4 would trigger St. Johns County wetland setback requirements that would eliminate three building lots, at a cost of $4,684 per lot. Meanwhile, the impacted wetland is small and of poor quality, and the filling of Wetland 4 can be offset by proposed mitigation. As a result, the costs of avoidance outweigh the environmental benefits of avoidance. Relying on ERP-A.H. 12.2.2.1 the Ginns did not perform reduction/elimination analyses for Wetlands 2 and 6, and the District did not require them. As explained in testimony, the District interprets ERP-A.H. 12.2.1.1 to require a reduction/elimination analysis only when a project will result in adverse impacts such that it does not meet the requirements of ERP-A.H. 12.2.2 through 12.2.3.7 and 12.2.5 through 12.3.8. But ERP-A.H. 12.2.2.1 does not require compliance with those sections for regulated activities in isolated wetlands less than one-half acre in size except in circumstances not applicable to this case: if they are used by threatened or endangered species; if they are located in an area of critical state concern; if they are connected at seasonal high water level to other wetlands; and if they are "more than minimal value," singularly or cumulatively, to fish and wildlife. See ERP-A.H. 12.2.2.1(a) through (d). Under the District's interpretation of ERP-A.H. 12.2.1.1, since ERP-A.H. 12.2.2.1 does not require compliance with the very sections that determine whether a reduction/elimination analysis is necessary under ERP-A.H. 12.2.1.1, such an analysis is not required for Wetlands 2 and 6. Relying on ERP-A.H. 12.2.1.2, a., the Ginns did not perform reduction/elimination analyses for Wetlands 3 and 7, and the District did not require them, because the functions provided by Wetlands 3 and 7 are "low" and the proposed mitigation to offset the impacts to these wetlands provides greater long-term value. Petitioners' environmental expert opined that an reduction/elimination analysis should have been performed for all of the wetlands on the project site, even if isolated and less than half an acre size, because all of the wetlands on the project site have ecological value. For example, small and isolated wetlands can be have value for amphibians, including the gopher frog. But his position does not square with the ERP- A.H., as reasonably interpreted by the District. Specifically, the tests are "more than minimal value" under ERP-A.H. 12.2.2.1(d) and "low value" under ERP-A.H. 12.2.1.2, a. Secondary Impacts The impacts to the wetlands and other surface waters are not expected to result in adverse secondary impacts to the water resources, including endangered or threatened listed species or their habitats. In accordance with ERP-A.H. 12.2.7(a), the design incorporates upland preserved buffers with minimum widths of 15 feet and an average width of 25 feet around the wetlands that will not be impacted. Sediment and erosion control measures will assure that the construction will not have an adverse secondary impact on water quality. The proposed development will be served by central water and sewer provided by the City of St. Augustine, eliminating a potential for secondary impacts to water quality from residential septic tanks or septic drainfields. In order to provide additional measures to avoid secondary impacts to Wetland 1, which is the location of the bald eagles’ nest, the Applicants proposed additional protections in a Bald Eagle Management Plan (BEMP) (App. Ex. 14). Under the terms of the BEMP, all land clearing, infrastructure installation, and exterior construction on homes located within in the primary zone (a distance within 750 feet of the nest tree) is restricted to the non-nesting season (generally May 15 through September 30). In the secondary zone (area between 750 feet and 1500 feet from the nest tree), exterior construction, infrastructure installation, and land clearing may take place during the nesting season with appropriate monitoring as described in the BEMP. Proposed Mitigation The Ginns have proposed mitigation for the purpose of offsetting adverse impacts to wetland functions. They have proposed to provide mitigation for: the 0.18-acre temporary impact to Wetland 1 during installation of a water/sewer line extending from existing City of St. Augustine service to the east (at Theodore Street); the impacts to Wetlands 3, 4 and 7; and the secondary impacts to the offsite portion of Wetland 4. The Ginns propose to grade the 0.18-acre temporary impact area in Wetland 1 to pre-construction elevations, plant 72 trees, and monitor annually for 5 years to document success. Although the easement is 30 feet in width, work will be confined to 20 feet where vegetation will be cleared, the top 1 foot of soil removed and stored for replacing, the trench excavated, the utility lines installed, the trench refilled, the top foot replaced, the area replanted with native vegetation, and re- vegetation monitored. To facilitate success, the historic water regime and historic seed source will give the re-vegetation effort a jump-start. The Ginns propose to restore and enhance a 0.12-acre portion of Wetland 1 that has been degraded by a trail road. They will grade the area to match the elevations of adjacent wetland, plant 48 trees, and monitor annually for 5 years to document success. This is proposed to offset the impacts to Wetland 4. The proposed grading, replanting, and monitoring will allow the area to be enhanced causing an environmental benefit. The Ginns propose to preserve 10.58 acres of wetlands and 3.99 acres of uplands in Wetland 1, 1 acre of upland buffers adjacent to Wetlands 1 and 5, and the 0.01 acre wetland in Wetland 5. The upland buffer will be a minimum of 15 feet wide with an average of 25 feet wide for Wetland 1 and 25 feet wide for Wetland 5. A conservation easement will be conveyed to the District to preserve Wetlands 1 and 5, the upland buffers, and the wetland restoration and enhancement areas. The preservation of wetlands provides mitigation value because it provides perpetual protection by ensuring that development will not occur in those areas, as well as preventing activities that are unregulated from occurring there. This will allow the conserved lands to mature and provide more forage and habitat for the wildlife that would utilize those areas. Mitigation for Wetlands 2 and 6 was not provided because they are isolated wetlands less than 0.5-acre in size that are not used by threatened or endangered species; are not located in an area of critical state concern; are not connected at seasonal high water level to other wetlands; and are not more than minimal value, singularly or cumulatively, to fish and wildlife. As previously referenced in the explanation of why no reduction/elimination analysis was required for these wetlands, ERP-A.H. 12.2.2.1(d) does not require compliance with under ERP- A.H. 12.3 through 12.3.8 (mitigation requirements) for regulated activities in isolated wetlands less than one-half acre in size except in circumstances found not to be present in this case. See Finding 44, supra. The cost of the proposed mitigation will be approximately $15,000. Operation and Maintenance A non-profit corporation that is a homeowners association (HOA) will be responsible for the operation, maintenance, and repair of the surface water management system. An HOA is a typical operation and maintenance entity for a subdivision and is an acceptable entity under District rules. See ERP-A.H. 7.1.1(e) and 7.1.2; Fla. Admin. Code R. 40C- 42.027(3) and (4). The Articles of Incorporation for the HOA and the Declaration of Covenants, Conditions, and Restrictions contain the language required by District rules. Water Quantity To address water quantity criteria, the Applicants' engineers ran a model (AdICPR, Version 1.4) to compare the peak rate discharge from the project in the pre-project state versus the peak rate discharge after the project is put in place. The pre-project data input into the model were defined by those conditions that existed in 1985 or 1986, prior to the partial work that was conducted, but not completed, on the site in the late 1980's. The project’s 1985/1986 site condition included a feature called Depression A that attenuated some onsite as well as offsite stormwater. Because of work that was done on the project site after 1985/1986 (i.e., the excavation of the borrow pit and road-clearing activities in the late 1980's), the peak rate of discharge for the 1985/1986 project site condition was lower than the peak rate of discharge for today’s project site condition. (Flooding at Mrs. McMulkin's house began after the work was performed on the project site in the late 1980's.) Because this partial work conducted in the late 1980's increased peak rate discharge from the site, by taking the pre-project conditions back to the time prior to that work, the peak rate of discharge in the 1985-86 pre-project condition was lower than it would be under today's conditions. The model results indicated that for the 25-year, 24- hour storm event, the pre-project peak rate discharge is 61.44 cubic feet per second (cfs). The post-project peak rate discharge is 28.16 cfs. Because the completed project reduces the pre-project peak rate discharges, the project will not cause any adverse flooding impacts off the property downstream. A similar analysis of the peak rate discharges under pre-project conditions that exist today (rather than in 1986) was compared to peak rate discharges for the post-project conditions. This analysis also showed post-project peak rate discharges to be less than the peak rate discharges from the site using today’s conditions as pre-project conditions. As further support to demonstrate that the project would not cause additional flooding downstream, a second modeling analysis was conducted, which is referred to as the Ravenswood Overall Watershed Model (OWM). The Applicants' engineer identified water flowing into the system from the entire watershed basin, including the project site under both the pre- and post-project conditions. The water regime was evaluated to determine what effect the proposed project will have on the overall peak rate discharges, the overall staging, and the duration of the staging within the basin that ultimately receives the water from the overall watershed. This receiving basin area was defined as the "wetland node" (Node 98 pre- project, and Node 99 post-project). As previously stated, the area within this "wetland node" includes more than just the portion of Wetland 1 that is located on the Ravenswood site. It also includes the areas to the south and east of the on-site Wetland 1 (including properties owned by the Petitioners) and extends down to an east-west ditch located just north of Josiah Street. The project’s surface water management system will not discharge to a landlocked basin. The project is not located in a floodway or floodplain. The project is not located downstream of a point on a watercourse where the drainage is five square miles or more. The project is impounding water only for temporary storage purposes. Based on testimony from their experts, Petitioners contend that reasonable assurances have not been given as to water quantity criteria due to various alleged problems regarding the modeling performed by the Ginns' engineer. Tailwater Elevations First, they raise what they call "the tailwater problem." According to Petitioners, the Ginns' modeling was flawed because it did not use a 19.27-foot SHW elevation in Wetland 1 as the tailwater elevation. The 19.27-foot SHW was identified by the Ginns' biologist in the Wetland 1 near the location of the proposed utility line crossing the wetland and was used as the pre-development tailwater in the analysis of the project site. The post-development tailwater condition was different because constructing the project would change the discharge point, and "tailwater" refers to the water elevation at the final discharge of the stormwater management system. (SW- A.H., Section 9.7) The post-development tailwater was 21 feet, which reflects the elevation of the top of the spreader swale that will be constructed, and it rose to 21.3 feet at peak flow over that berm. For the OWM, the final discharge point of the system being modeled was the east-west ditch located just north of Josiah Street, where the tailwater elevation was approximately 18.1 feet, not the 19.27 feet SHW mark to the north in Wetland 1. The tailwater condition used in the modeling was correct. Petitioners also mention in their PRO that "the Applicants' analysis shows that, at certain times after the 25 year, 24 hour storm event, in the post development state, Wetland 1 will have higher staging than in the predevelopment state." But those stages are after peak flows have occurred and are below flood stages. This is not an expected result of post- development peak-flow attenuation. Watershed Criticism The second major criticism Petitioners level at the Applicants' modeling is that parts of the applicable watershed basins were omitted. These include basins to the west of the project site, as well as basins to the north of the site, which Petitioners lumped into the so-called "tailwater problem." Petitioners sought to show that the basins identified by the Ginns as draining onto the project site from the west were undersized, thus underestimating the amount of offsite water flowing onto the project site. With respect to Basin C, Petitioners' witness testified that the basin should be 60 acres instead of 30 acres in size, and that consequently more water would flow into pond DA-2 and thus reduce the residence time of the permanent pool volume. In fact, Basin C is 16 acres in size, not 30 acres. The water from Basin C moves onto the project site over the western project boundary. A portion of the water from Basin C will be directed to pond DA-2 through an inlet structure, and the rest will move over an irregular weir and around the project site. With respect to Basin D, Petitioners' witness testified that the basin should encompass an additional 20 acres to the west and north. West of Basin D, there are ditches routing water flow away from the watershed, so it is unclear how water from an additional 20 acres would enter the watershed. The western boundary of the OWM is consistent with the western boundaries delineated in two studies performed for St. Johns County. Petitioners' witness testified that all of the water from the western offsite basins currently travels across the project site's western boundary, and that in post-development all of that water will enter pond DA-2 through the inlet structure. In fact, currently only the water from Basin C flows across the project site's western boundary. Post-development, only a portion of water from Basin C will enter pond DA-2. Currently and post-development, the water in Basin D travels north to a ditch south of Ravenswood Drive and discharges into Wetland 1. Petitioners also sought to show that a 50-acre area north of the project site should have been included in the OWM. Petitioners' witness testified that there is a "strong possibility" that the northern area drains into the project site by means of overtopping Ravenswood Drive. The witness' estimate of 50 acres was based on review of topographical maps; the witness has not seen water flowing over Ravenswood Drive. The Ginns' engineer testified that the area north of Ravenswood Drive does not enter the project site, based on his review of two reports prepared by different engineering firms for St. Johns County, conversations with one of those engineering firms, conversations with the St. Johns County engineer, reviews of aerials and contour maps, and site observations. Based on site observations, the area north of the project site drains north and then east. One report prepared for St. Johns County did not include the northern area in the watershed, and the other report included an area to the north consisting of 12 acres. The Ginns' engineer added the 12-acre area to the OWM and assumed the existence of an unobstructed culvert through which this additional water could enter Wetland 1, but the model results showed no effect of the project on stages or duration in the wetland. Even if a 50-acre area were included in the OWM, the result would be an increase in both pre-development and post- development peak rates of discharge. So long as the post- development peak rate of discharge is lower than the pre- development peak rate of discharge, then the conveyance system downstream will experience a rate of water flow that is the same or lower than before the project, and the project will not cause adverse flooding impacts offsite. Petitioners' witness did not have any documents to support his version of the delineations of Basins C and D and the area north of Ravenswood Drive. Time of Concentration Time of concentration (TC) is the time that it takes a drop of water to travel from the hydraulically most distant point in a watershed. Petitioners sought to show that the TC used for Basin C was incorrect. Part of Petitioners' rationale is related to their criticism of the watersheds used in the Ginns' modeling. Petitioners' witness testified that the TC was too low because the distance traveled in Basin C should be longer because Basin C should be larger. The appropriateness of the Basin C delineation already has been addressed. See Finding 71, supra. Petitioners' witness also testified that the TC used for the post-development analysis was too high because water will travel faster after development. However, the project will not develop Basins C and D, and thus using the same TC in pre- development and post-development is appropriate. The project will develop Basins A and B (called Basins 1, 2, and 3 post- development), and the post-development TC for those basins were, in fact, lower than those used in the pre-development analysis. Groundwater Infiltration in DA-2 One witness for Petitioners opined that groundwater would move up through the bottom of DA-2 as a result of upwelling (also referred to as infiltration or seepage), such that 1,941 gallons per day (gpd) would enter DA-2. That witness agreed that if a liner were installed in a portion of DA-2, the liner would reduce upwelling in a portion of the pond. Another witness for Petitioners opined that 200 gpd of groundwater would enter the eastern part and 20,000 gpd would enter the western part of DA-2. Although that witness stated that upwelling of 200 gpd is not a significant input and that upwelling of 20,000 gpd is a significant input, he had not performed calculations to determine the significance. Even if more than 20,000 gpd of groundwater entered DA-2, DA-2 will provide sufficient permanent pool residence time without any change to the currently designed permanent pool size or the orifice size. Although part of one system, even if DA-2 is considered separate from DA-1, DA-2 is designed to provide an additional permanent pool volume of 6.57 acre-feet (in addition to the 20.5 acre/feet provided by DA-1). This 6.57 acre-feet provided by DA-2, is more than the 4.889 acre-feet of permanent pool volume that would be necessary to achieve a 21-day residence time for the 24+ acres that discharge directly into DA-2, as well as background seepage into DA-2 at a rate of 0.0403 cfs, which is more upwelling than estimated by Petitioners' two witnesses. There is adequate permanent pool volume in DA-2 to accommodate the entire flow from Basin C and for water entering through the pond bottom and pond sides and provide at least 21 days of residence time. Water Quality Criteria Presumptive Water Quality The stormwater system proposed by the Ginns is designed in accordance with Florida Administrative Code Rules 40C-42.024, 40C-42.025, and 40C-42.026(4). Wet detention ponds must be designed for a permanent pool residence time of 14 days with a littoral zone, or for a residence time of 21 days without a littoral zone, which is the case for this project. See Fla. Admin. Code R. 40C-42.026(4)(c) and (d). DA-1 and DA-2 contain sufficient permanent pool volume to provide a residence time of 31.5 days, which is the amount of time required for projects that discharge to Class II Outstanding Florida Waters, even though the receiving waterbody for this project is classified as Class III Waters. See Fla. Admin. Code R. 40C-42.026(4)(k)1. Best management practices will be used during project construction to address erosion and sediment control. Such measures will include silt fences around the construction site, hay bales in ditches and inlets, and maintenance of construction equipment to prevent release of pollutants, and may include staked sod on banks and turbidity barriers if needed. In addition, the District proposed permit conditions that require erosion and sediment control measures to be implemented. (Dist. Ex. 1, pp. 8-9, #4; Dist. Ex. 2, p. 1, ##3, 4, and 5, and p. 6, #10). ERP/MSSW/Stormwater Special Conditions incorporated into the proposed permit require that all wetland areas or water bodies outside the specific limits of construction must be protected from erosion, siltation, scouring or excess turbidity, and dewatering. (Dist. Ex. 2). The District also proposed a permit condition that requires District approval of a dewatering plan for construction, including DA-1 and DA-2, within 30 days of permit issuance and prior to construction. The Ginns intend to retain the dewatering from construction on the project site. As previously described, Petitioners' engineering witness sought to show that DA-2 will not provide the required permanent pool residence time because Basin C should be 60 acres in size. Petitioners' environmental witness also expressed concern about the capacity of the ponds to provide the water quality treatment required to meet the presumptive water quality criteria in the rules, but those concerns were based on information he obtained from Petitioners' engineering witness. Those issues already have been addressed. See Findings 77-78, supra. Groundwater Contamination Besides those issues, Petitioners raised the issue that groundwater contamination from a former landfill nearby and from some onsite sludge and trash disposal could be drawn into the proposed stormwater management system and cause water quality violations in the receiving waters. If groundwater is contaminated, the surface water management system could allow groundwater to become surface water in proposed DA-1. St. Johns County operated a landfill from the mid-1950s to 1977 in an area northwest of the project site. The landfill accepted household and industrial waste, which was buried in groundwater, which in turn could greatly enhance the creation of leachate and impacted water. Groundwater flows from west to east in the vicinity of the landfill and the project site but there was conflicting evidence as to a minor portion of the property. The Ginns' witness testified that if the landfill extended far enough south, a small part of the project site could be downgradient from the landfill. But there was no evidence that the landfill extended that far south. Petitioners' witness testified that the groundwater flow varies on the south side of the landfill so that groundwater might flow southeast toward the site. Even if Petitioners' witness is correct, the surface water management system was designed, as Petitioners' other witness agreed, so that DA-1 would have minimal influence on groundwater near the pond. In 1989, sewage sludge and garbage were placed in a pit in the central part of the project site, north of the existing pond, which also is the area for proposed DA-1; and at various times refuse--including a couple of batteries, a few sealed buckets, and concrete--has been placed on the surface of the site. In 1989, to determine the amount of sewage and garbage on the project site, the St. Johns County Health Department chose several locations evidencing recent excavation south of Ravenswood Drive, had the areas re-excavated, and found one bag of garbage and debris such as tree stumps and palmettos. In 2001, an empty 55-gallon drum was on the site; there was no evidence what it once contained or what it contained when deposited onsite, if anything. In addition, trespassers dumped solid waste on the property from time to time. Petitioners' witness searched the site with a magnetometer and found nothing significant. On the same day, another of Petitioners’ witnesses sampled with an auger but the auger did not bore for core or any other type sample; it merely measured groundwater level. In 1985, 1999, and 2000, groundwater offsite of the project near the landfill was sampled at various times and places by various consultants to determine whether groundwater was being contaminated by the landfill. The groundwater sampling did not detect any violations of water quality standards. Consultants for the Ginns twice sampled groundwater beneath the project site and also modeled contaminant migration. The first time, in 2001, they used three wells to sample the site in the northwest for potential impacts to the property from the landfill. The second time, they sampled the site through cluster wells in the northwest, middle, and south. (Each cluster well samples in a shallow and in a deeper location.) The well locations were closest to the offsite landfill and within an area where refuse may have been buried in the north- central part of the site. Due to natural processes since 1989, no sewage sludge deposited onsite then would be expected to remain on the surface or be found in the groundwater. The evidence was that the sewage sludge and garbage were excavated. Although samples taken near the center of the property contained substances that are water quality parameters, they were not found in sufficient concentration to be water quality violations. There is an iron stain in the sand north of the existing pond in the area where pond DA-1 is to be located. Based on dissolved oxygen levels in the groundwater, Petitioners' witness suggested that the stain is due to buried sewage, but the oxygen levels are not in violation of water quality standards and, while toward the low end of not being a violation, the levels could be due to natural causes. No evidence was presented establishing that the presence of the iron stain will lead to a violation of water quality standards. Petitioners' witness, Mr. Boyes, testified that iron was a health concern. But iron itself is a secondary drinking water standard, which is not a health-based standard but pertains to odor and appearance of drinking water. See § 403.852(12) and (13), Fla. Stat. Petitioners argued that the Phase I study was defective because historical activity on the project site was not adequately addressed. But the Phase I study was only part of the evidence considered during this de novo hearing. Following up on the Phase I study, the 2001 sampling analyzed for 68 volatile organics and 72 semi-volatile organics, which would have picked up solvents, some pesticides, petroleum hydrocarbons, and polynuclear aromatic hydrocarbons--the full range of semi-volatile and volatile organics. The sampling in August 2003 occurred because some of the semi-volatile parameters sampled earlier needed to be more precisely measured, and it was a much broader analysis that included 63 semi-volatiles, 73 volatile organic compounds, 23 polynuclear aromatic hydrocarbons, 25 organic phosphate pesticides, 13 chlorinated herbicides, 13 metals, and ammonia and phosphorus. The parameters for which sampling and analyses were done included parameters that were representative of contaminants in landfills that would have now spread to the project site. They also would have detected any contamination due to historical activity on the project site. Yet groundwater testing demonstrated that existing groundwater at the project site meets state water quality standards. Based on the lack of contaminants found in these samples taken from groundwater at the project site 50 years after the landfill began operation, the logical conclusion is that either groundwater does not flow from the landfill toward the project site or that the groundwater moving away from the landfill is not contaminated. Groundwater that may enter the stormwater ponds will not contain contaminants that will exceed surface water quality standards or groundwater quality standards. Taken together, the evidence was adequate to give reasonable assurances that groundwater entering the stormwater ponds will not contain contaminants that exceed surface water quality standards or groundwater quality standards and that water quality violations would not occur from contaminated water groundwater drawn into the proposed stormwater management system, whether from the old landfill or from onsite waste disposal. The greater weight of the evidence was that there are no violations of water quality standards in groundwater beneath the project site and that nothing has happened on the site that would cause violations to occur in the future. Contrary to Petitioners' suggestion, a permit condition requiring continued monitoring for onsite contamination is not warranted. J. Fish and Wildlife Except for the bald eagle nest, all issues regarding fish and wildlife, listed species, and their habitat as they relate to ERP-A.H. 12.2.2 through 12.2.2.4 already have been addressed. When the Ginns were made aware in November 2003 that there was an eagle nest in Wetland 1, they retained the services of Tony Steffer, an eagle expert with over 25 years of experience working specifically with eagles and eagle management issues, including extensive hands-on experience with eagles and the conduct of field studies, aerial surveys, and behavioral observations as well as numerous research projects on the bald eagle. Mr. Steffer visited the Ravenswood site on numerous occasions since the discovery of the nest, made observations, and was integral in the drafting of the Ravenswood BEMP. It is Mr. Steffer’s opinion that the proposed project, with the implementation of the BEMP, will not adversely affect the eagles. This opinion was based on Mr. Steffer's extensive knowledge and experience with eagle behavior and human interactions. In addition, Mr. Steffer considered the physical characteristics of the Ravenswood site and the nest tree, the dense vegetation in Wetland 1 surrounding the nest site, and the existing surrounding land uses, including the existing residential community that lies a distance of about 310 feet from the nest site, the existing roadways and associated traffic, and the school (with attendant playground noise) that is to north of the site. In Mr. Steffer's opinion, the eagles are deriving their security from the buffering effects provided by the surrounding wetland. He observed that the nesting and incubating eagles were not disturbed when he set up his scope at about 300-320 feet from the tree. The BEMP requires that Wetland 1, and the upland islands located within it, be preserved and limits the work associated with the water/sewer line to the non-nesting season. With the BEMP implemented, Mr. Steffer expressed confidence that the Ravenswood eagles would be able to tolerate the proposed activities allowed under the BEMP. The Ravenswood project plans and the BEMP were reviewed by the U.S. Fish and Wildlife Service (USFWS). The USFWS analyzed information in their files relating to projects which proposed activities within the primary zone of an eagle nest and reported abandoned nests. None of the reported abandoned nests could be attributed to human activities in and around the nest tree. Based on the project plans, the terms of the BEMP, and this analysis, the USFWS concluded that the Ravenswood project "is not likely to adversely affect" the bald eagles at the Ravenswood site. According to the coordination procedures agreed to and employed by the USFWS and the Florida Fish and Wildlife Conservation Commission (FFWCC), the USFWS takes the lead in reviewing bald eagle issues associated with development projects. In accordance with these procedures, for the Ravenswood project, the USFWS coordinated their review and their draft comments with the FFWCC. The FFWCC concurred with the USFWS’s position that the project, with the implementation of the BEMP, will not adversely affect the Ravenswood eagles or their nest. This position by both agencies is consistent with the expert testimony of Mr. Don Palmer, which was based on his 29 years of experience with the USFWS in bald eagle and human interactions. Petitioners and their witnesses raised several valid concerns regarding the continued viability of the Ravenswood eagle nest during and after implementation of the proposed project. One concern expressed was that parts of the Habitat Management Guidelines for the Bald Eagle in the Southeast Region (Eagle Management Guidelines) seem inconsistent with the proposed project. For example, the Eagle Management Guidelines state: "The emphasis [of the guidelines] is to avoid or minimize detrimental human-related impacts on bald eagles, particularly during the nesting season." They also state that the primary zone, which in this case is the area within a 750 foot radius of the nest tree, is "the most critical area and must be maintained to promote acceptable conditions for eagles." They recommend no residential development within the primary zone "at any time." (Emphasis in original.) They also recommend no major activities such as land clearing and construction in the secondary zone during the nesting season because "[e]ven intermittent use or activities [of that kind] of short duration during nesting are likely to constitute disturbance." But the eagle experts explained that the Eagle Management Guidelines have not been updated since 1987, and it has been learned since then that eagles can tolerate more disturbance than was thought at that time. Another concern was that the Ravenswood eagles may have chosen the nest site in Wetland 1 not only for its insulation from existing development to the north and east but also for the relatively sparse development to the west. Along those lines, it was not clear from the evidence that the eagles are used to flying over developed land to forage on the San Sebastian River and its estuaries to the east, as the eagle experts seemed to believe. Mr. Mills testified that eagles have been seen foraging around stocked fish ponds to the west, which also could be the source of catfish bones found beneath the Ravenswood nest. But it is believed that the confident testimony of the eagle experts must be accepted and credited notwithstanding Petitioners' unspecific concerns along these lines. Finally, Petitioners expressed concern about the effectiveness of the monitoring during the nesting required under the BEMP. Some of Petitioners' witnesses related less-than-perfect experiences with eagle monitoring, including malfeasance (monitors sleeping instead of monitoring), unresponsive developers (ignoring monitors' requests to stop work because of signs of eagle disturbance, or delaying work stoppage), and indications that some eagle monitors may lack independence from the hiring developer (giving rise, in a worst case, to the question whether an illegal conspiracy exists between them to ignore signs of disturbance when no independent observer is around). Notwithstanding these concerns, Petitioners' witnesses conceded that eagle monitoring can be and is sometimes effective. If Mr. Steffer is retained as the eagle monitor for this project, or to recruit and train eagle monitors to work under his supervision, there is no reason to think that eagle monitoring in this case will not be conducted in good faith and effectively. Even if the Ginns do not retain Mr. Steffer for those purposes, the evidence did not suggest a valid reason to assume that the Ginns' proposed eagle monitoring will not be conducted in good faith and effectively. K. Other 40C-4.301 Criteria – 40C-4.301(1)(g)-(k) 40C-4.301.301(1)(g) - No minimum surface or groundwater levels or surface water flows have been established pursuant to Florida Administrative Code Rules Chapter 40C-8 in the area of the project. 40C-4.301.301(1)(h) - There are no works of the District in the area of the project. 40C-4.301.301(1)(i) - The proposed wet detention system is typical and is based on accepted engineering practices. Wet detention systems are one of the most easily maintained stormwater management systems and require very little maintenance, just periodically checking the outfall structure for clogging. 40C-4.301.301(1)(j) - The Ginns own the property where the project is located free from mortgages and liens. As previously indicated, they will establish an operation and maintenance entity. The cost of mitigation is less than $25,000 so that financial responsibility for mitigation was not required to be established. (Costs associated with the proposed BEMP are not included as part of the Ginns' mitigation proposal.) 40C-4.301.301(1)(k) - The project is not located in a basin subject to special criteria. Public Interest Test in 40C-4.302 The seven-factor public interest test is a balancing test. The test applies to the parts of the project that are in, on, or over wetlands, and those parts must not be contrary to the public interest unless they are located in, on, or over an Outstanding Florida Water (OFW) or significantly degrade an OFW, in which case the project must be clearly in the public interest. No part of the project is located within an OFW. Balancing the public interest test factors, the project will not be contrary to the public interest. 40C-4.302(1)(a)1. - The project will not adversely affect the public health, safety, or welfare or the property of others because the surface water management system is designed in accordance with District criteria, the post-development peak rate of discharge is less than the pre-development peak rate of discharge, and the project will not cause flooding to offsite properties. 40C-4.302(1)(a)2. - Mitigation will offset any adverse impacts of the project to the conservation of fish and wildlife or their habitats, and the BEMP is designed to prevent adverse effects on the Ravenswood eagles. Although active gopher tortoise burrows were observed on the site, the impacts to these burrows are addressed by the FFWCC’s incidental take permit. The mitigation that is required as part of that permit will adequately offset the impacts to this species. 40C-4.302(1)(a)3. - The project will not adversely affect navigation or cause harmful shoaling. The project will not adversely affect the flow of water or cause harmful erosion. The project's design includes erosion and sediment control measures. The project's design minimizes flow velocities by including flat slopes for pipes. The stormwater will be discharged through an upsized pipe, which will reduce the velocity of the water. The stormwater will discharge into a spreader swale (also called a velocity attenuation pond), which will further reduce the velocity and will prevent erosion in Wetland 1. The other findings of fact relevant to this criterion are in the section entitled "Water Quantity." See Findings 61-67, supra. 40C-4.302(1)(a)4. – Development of the project will not adversely affect the legal recreational use of the project site. (Illegal use by trespassers should not be considered under this criterion.) There also will not be any adverse impact on recreational use in the vicinity of the project site. Wetlands 1 and 5 may provide benefit to marine productivity by supplying detritus to the marine habitat, and these wetlands will remain. 40C-4.302(1)(a)5. - The project will be of a permanent nature except for the temporary impacts to Wetland 1. Mitigation will offset the temporary adverse impacts. 40C-4.302(1)(a)6. - The District found no archeological or historical resources on the site, and the District received information from the Division of Historical Resources indicating there would be no adverse impacts from this project to significant historical or archeological resources. 40C-4.302(1)(a)7. - Considering the mitigation proposal, and the proposed BEMP, there will be no adverse effects on the current condition and relative value of functions being performed by areas affected by the proposed project. The proposed project is no worse than neutral measured against any one of these criteria, individually. For that reason, it must be determined that, on balance, consideration these factors indicates that the project is not contrary to the public interest. Other 40C-4.302 Criteria The proposed mitigation is located within the same drainage basin as the project and offsets the adverse impacts so the project would not cause an unacceptable cumulative impact. The project is not located in or near Class II waters. The project does not contain seawalls and is not located in an estuary or lagoon. The District reviewed a dredge and fill violation that occurred on the project site and was handled by the Department of Environmental Regulation (DER) in 1989. The Ginns owned the property with others in 1989. Although they did not conduct the activity that caused the violation, they took responsibility for resolving the matter in a timely manner through entry of a Consent Order. The evidence was that they complied with the terms of the Consent Order. Applicants' Exhibit 30K was a letter from DER dated February 13, 1991, verifying compliance based on a site inspection. Inexplicably, the file reference number did not match the number on the Consent Order. But Mr. Ginn testified that he has heard nothing since concerning the matter either from DER, or its successor agency (the Department of Environmental Protection), or from the District. The evidence was that the Ginns have not violated any rules described in Florida Administrative Code Rule 40C- 4.302(2). There also was no evidence of any other DER or DEP violations after 1989.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the St. Johns River Water Management District enter a final order issuing to Jay and Linda Ginn ERP number 40-109-81153-1, subject to the conditions set forth in District Exhibits 1, 2, and 10. DONE AND ENTERED this 16th day of April, 2004, in Tallahassee, Leon County, Florida. S J. LAWRENCE JOHNSTON Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 16th day of April, 2004.
The Issue The issue to be determined is whether the applicants, William Guererro and Christina Bang, a/k/a Christina Guerrero (Applicants), are entitled to issuance of a Consolidated Environmental Resource Permit and State Lands Approvals for various structures on the Applicants’ property at 58458 Overseas Highway, Marathon, Florida.
Findings Of Fact The Parties Petitioners Bernard Spinrad and Marian Spinrad are the owners of adjoining parcels of property with the addresses of 58418 and 58420 Overseas Highway, Marathon, Florida. They acquired the property in December 2001. They recently completed construction of two residential structures on the properties. The structure at 58418 Overseas Highway is currently listed for sale. The structure at 58420 Overseas Highway is a vacation rental property. Neither structure is Petitioners’ permanent residence. The DEP is the state agency with the power and duty to regulate activities in waters of the state pursuant to chapter 373, Florida Statutes. The DEP also serves as staff to the Board of Trustees of the Internal Improvement Trust Fund (“Board of Trustees”) to review and act on activities on state sovereignty submerged lands under chapter 253. The Applicants, are the owners of adjoining parcels of property with the address of 58478 Overseas Highway, Marathon, Florida (the Property). They purchased the Property in June 2010. The structures that are the subject of the Permit are to be constructed near or waterward of the shoreline of the Property. The Property The Property is located on Grassy Key, an island in the middle Florida Keys, within limits of the city of Marathon, Monroe County, Florida. U.S. Highway 1 passes through Grassy Key. The Property -- as is that of Petitioners -- is situated between U.S. Highway 1 and the open waters of the Atlantic Ocean. In the early part of the 20th century, a portion of Grassy Key was platted as the Crains Subdivision. The properties owned by Applicants and Petitioners are within the Crains Subdivision. During the periods of time directly relevant hereto, the Property has been owned by Burgess Levine, who owned the property during the period prior to the October 2006, landfall of Hurricane Wilma until June 2010, and by Applicants, who have owned the Property since June, 2010. Grassy Key Grassy Key is three-miles long, and has 6800 feet of beaches, none of which are designated as critically eroded. The island fronts the Atlantic Ocean to the east, and the more protected waters of Florida Bay to the west. The waters along the Atlantic Ocean shoreline of Grassy Key in the area at issue are shallow, with an extremely flat bottom having a very gradual slope of approximately 1 to 30, meaning there is a one foot vertical change over 30 horizontal feet. The mean tide range at the Property is about 1.7 feet. Under normal conditions, the stretch of Grassy Key at issue is fairly characterized as a zero-wave energy shoreline. Waves break well offshore and there is negligible wave energy propagating beyond that point. What shoreline energy exists is produced by small tide currents and wind-shear on the water surface that moves water along the shoreline. The direction of the water movement is dependent on tides and wind direction, with the predominant direction being from north to south. Erosive and other significant changes to the shoreline of Grassy Key, including that stretch fronting the Property, are event driven, meaning when there is a coastal storm that causes a rise in the water level, substantially higher than the astronomical tide, waves can propagate onto the shoreline of Grassy Key. The wind and waves can come from virtually any direction depending on the storm. A storm of greater intensity will create higher energy-wave conditions. Although storm conditions may only occur over 1 to 3 percent of a given year, with the rest of the year having zero-wave energy, on average the coastline may be considered to be of moderate-wave energy. The beach sediment along the Grassy Key shoreline in all areas pertinent hereto consists of calcareous material, made up of the breakdown of corals and coralling algae, with a significant fraction of other detrital marine material. The upper beaches of Grassy Key, including that on the Property, generally consist of coarse, calcareous sand with a small fraction of calcareous silt-size particles. The inter-tidal areas along Grassy Key consist of predominantly fine calcareous sand, with a greater fraction of calcareous silt. Extending out into the nearshore area all along Grassy Key, including that fronting the properties owned by Petitioners and Applicants, the sediment becomes a very fine calcareous sand, with a greater fraction of the material being calcareous silts and clays, and with a substantial amount of organic mud of a marine origin, classified as Islamorada muck. Since at least the 1970s, one wading in the nearshore waters along Grassy Key could expect to sink into the surface muck to a depth of anywhere from six inches to two feet. The depth of muck becomes less as one moves further out and approaches the offshore Thalassia beds. Although some areas offer more resistance than others, it is routine to experience difficulty in walking and wading along the coast of Grassy Key because of the high percentage of clays and silts in the substrate. The band of muck narrows as one proceeds towards the northern stretches of Grassy Key, until one reaches the furthest areas to the northeast where the nearshore transitions to exposed rock and hard bottom. The surface muck that exists in the nearshore waters of Grassy Key, having a sizable component of decaying organic material, gives off an odor of hydrogen sulfide when disturbed that some find to be unpleasant. The odor is a naturally- occurring condition of the sediment, and is common in mucky areas all around the southern coasts of Florida. The suggestion that the shoreline in the vicinity of the Petitioners’ property, and that of Applicants, was a naturally occurring white, sandy beach is contrary to the greater weight of the evidence. To the extent the shoreline at Petitioners’ property may have been temporarily altered by the overwash from Hurricane Wilma as discussed herein, Petitioners’ own post-Wilma man-made efforts at beach stabilization, or the redistribution of sediments occasioned by Hurricanes Isaac and Sandy in 2012, the evidence demonstrates the “mucky” condition described herein to be more consistent with the natural and long-standing conditions of Grassy Key. Thus, as Grassy Key exists in the present time, one may expect to encounter six inches to two feet of loose muck anywhere along the nearshore area. Close to shore of Grassy Key are scattered beds of Halodule, a species of seagrass that tends to emerge and grow in shallow waters. The growth of Halodule is influenced by the nature of the sediments, the salinity temperature, and clarity of the water. Storm events have a significant effect on its growth. Given its transient nature, Halodule may vary in any given area from nonexistent, to spotty, to well-established beds. As one moves further offshore, the Halodule transitions to large, continuous beds of Thalassia. Thalassia grows in deeper water, and is common to a depth of about 12 feet. Being deeper and less affected by storm energy, the line of the Thalassia beds off of Grassy Key has not substantially changed over time. As wind and waves come across the grass beds, and as tides ebb and flow, grass blades are cropped. The amount of grass varies seasonally to a degree. The cropped and dislodged seagrasses, along with other organic material entrained therein, are naturally carried by the tides and wind and stranded along the shoreline. The stranded material is known as wrack, and the line of stranded material is known as the wrack line. Grassy Key is well known for the large seagrass wracks that pile up on the shoreline. A wrack line is a normal and natural occurrence in marine environments like that of Grassy Key, and can be a good indicator of the upper edge of the water action at a particular time. The cropping and dislodging of seagrass is accentuated during major or minor storm events. During Hurricane Rita in 2005, a very large seagrass wrack was blown onto the shoreline of Grassy Key. It was subsequently blown back out to sea by the overwash from Hurricane Wilma. The decomposition of the seagrass and other organic materials creates a significant odor that is not uncommon. That odor of decomposing material is well-recognized as being associated with Grassy Key. Areas along the shoreline of Grassy Key have been used by sea turtles for nesting. However, the nature of the substrate in the area of the Property is not optimal for nesting. Generally, sea turtles require a nesting site with 15 to 20 inches of sand above the water table so as to allow them to dig a suitably deep and dry cavity for their eggs. The natural substrate along the section of Grassy Key at issue is coarser and more difficult to dig into, and does not have the depth of sand for the best chance of a successful nest. Despite the nature of the substrate, Petitioner testified as to her observation of turtle nests along her property in each year from 2006 through 2010. Since the SW Groin, the Mid-bulkhead, and the NE Groin were all in existence and functioning during that period, with work to the SW Groin having been completed by 2008, the preponderance of the evidence demonstrates that those structures have no effect on the success or failure of sea turtles to nest along the property. To the extent nesting has been disrupted since 2011, the most logical inference that can be drawn from the evidence is that such disruption is the result of the Mid-Jetty Extension, which is slated for removal under the terms of the Permit. The preponderance of the evidence demonstrates that the structures and activities authorized by the Permit will have no adverse effect on sea turtles. Hurricane Wilma In October, 2005, Grassy Key was pounded by Hurricane Wilma. The storm passed to the north, and created a substantial storm surge that moved from west to east across Grassy Key. The storm surge created a “ridge and runnel” effect on the Atlantic facing shoreline, with the channelization of the storm tide flow creating erosion and gullies on upland shore-adjacent properties. The storm surge and flooding across Grassy Key caused substantial wash-outs of sand; transported a large volume of sandy, upland sediments into the nearshore waters of the Atlantic Ocean; and created washover “fans” of material along the shoreline of Grassy Key. The effects of the Hurricane Wilma storm surge manifested just north of the Property, became substantial at the Property, and continued south down the shoreline for a considerable distance. At the Property, sand was pushed from 50 to 100 feet waterward from the existing shoreline, and a substantial runout was created running parallel and north of the SW Jetty. The sand pushed into the water buried everything in its path, including seagrasses. In short, the post-Wilma shoreline from the Property south along Grassy Key was left in a completely disrupted state. The nearshore waters fronting the properties owned by Petitioners and Applicants were affected by the deposition of sandy, upland sediments, which temporarily created areas of substantially harder-packed sediment. Over time, as the shoreline equilibrated and the sandy sediment distributed through a broader area, more typical shoreline conditions returned. The photographic evidence demonstrates that the Mid- bulkhead and the SW jetty structures were impacted by the Hurricane Wilma storm surge. In addition, the sandy area between the mid-bulkhead and the SW jetty was pushed seaward from its previous location. The scars from Hurricane Wilma remain evident through the most recent aerial photographs received in evidence. It is visually apparent that seagrass, though reappearing in patches, has not reestablished in the nearshore areas along the affected shoreline of Grassy Key -- including the areas in front of the Property and the property owned by Petitioners -- to the extent that it existed prior to the storm. Post-Wilma Activities When Hurricane Wilma hit, the Property was owned by Burgess Lea Levine. Not long after Hurricane Wilma, Ms. Levine shored up the SW Jetty, and performed work in the “beach” area between the mid-bulkhead and the SW jetty. The photographic evidence also supports a finding that the rock outline of the Mid-jetty was reestablished to its pre-Wilma configuration. The repairs to the SW Jetty resulted in a structure that is virtually indistinguishable in size and shape to the SW Jetty as it presently exists. The wrack line at the beach area after it was “worked” following the passage of Wilma, shows the area in which work was done to be generally consistent with -- though slightly seaward of -- the 2005 post-Wilma shoreline. In 2008, Ms. Levine applied for a series of exemptions and for consent of use for state-owned lands for “shoreline repair, replace earthen ramp with a concrete ramp, repair wood deck, replace mooring piles & maintenance dredge existing channel w/in Atlantic Ocean.” On September 19, 2008, the DEP issued a regulatory authorization and proprietary submerged land approval. The Rights of Affected Parties that accompanied the September 19, 2008, notice provided that “[t]his letter acknowledges that the proposed activity is exempt from ERP permitting requirements” and that “this determination shall expire after one year.” The notice of Rights of Affected Parties did not apply to the proprietary authorization. At some time after issuance of the regulatory authorization, Ms. Burgess initiated additional work to repair the SW Jetty. The photographic evidence, which is persuasive, indicates that the work on the SW Jetty, including the concrete cap, was complete by the end of 2008. When Applicants purchased the Property, the determination of exemption issued in 2008 had, by application of the notice of Rights of Affected Parties, expired. Shortly after the Applicants purchased the property, they had the existing family home demolished. Applicants intend to construct a winter vacation home for their personal use on the property. 2012 Storms In August and October 2012, Grassy Key was subject to event-driven conditions as a result of the passage of Hurricanes Isaac and Sandy. Those storms redistributed large areas of sediments that had been moved offshore by the effects of Hurricane Wilma. The Proposed Permit The February 20, 2013, Permit provides that the structures described herein do not require the issuance of an Environmental Resource Permit, subject to the criteria and conditions in Florida Administrative Code Rule 40E-4.051. The Permit provides that the boat ramp is eligible to use the general permit in Florida Administrative Code Rule 62-330.417, the repair and replacement of the dock is exempt pursuant to section 403.813(1)(b), Florida Statutes, the maintenance dredging of the Channel is exempt pursuant to section 403.813(1)(f), and that the repair and replacement of the NW Jetty, the SW Jetty, and the Mid-bulkhead are exempt because the structures are “historic in nature and pre-dates Department regulations.” In addition to the regulatory authorizations, the Permit granted proprietary authorization by Letter of Consent for the dock pursuant to Florida Administrative Code Rule 18- 21.005(1)(c)4., and for the Channel, the NW Jetty, the SW Jetty, and the Mid-bulkhead pursuant to rule 18-21.005(1)(c)7. The Permit established the mean high-water line as that existing in 1974 and depicted on the “Richmond Survey.” Proprietary authorization for the boat ramp was determined to be unnecessary due to its location above the mean high-water line. Finally, proprietary authorization for the “Sandy Area” or beach between the Mid-bulkhead and SW Jetty was granted by Letter of Consent pursuant to rule 18-21.005(1). On September 20, 2013, the DEP filed a Notice of Additional Grounds for Exemption Determination, in which it found each of the structures subject to the regulatory review to “have only minimal or insignificant individual or cumulative adverse impacts on water resources” and to thus be exempt from the need to obtain an Environmental Resource Permit pursuant to section 373.406(6), Florida Statutes. On December 12, 2013, Applicants filed a Notice of Filing Proposed Changes to the Pending Agency Action in which they agreed to certain additional conditions, and which referenced the October 1, 2013, repeal of rule 40E-4.051, and its replacement by the “Statewide ERP rules.” For purposes of this de novo proceeding, the proposed Permit at issue includes the February 20, 2013, Permit; the September 20, 2013, Notice of Additional Grounds for Exemption Determination; and the December 12, 2013, Notice of Filing Proposed Changes to the Pending Agency Action. The Proposed Structures Groins There has been some confusion relating to the names of the structures that are subject to the proposed Permit. Two of the structures are referred to as jetties, the NE Jetty and the SW Jetty, and the middle structure is referred to as the Mid- bulkhead. A jetty is a navigation structure that is constructed at a barrier inlet. Its purpose is to stabilize the inlet and prevent shoaling by “jetting” current and wave-driven sand further offshore, such that the offshore bar is moved into deep enough water to allow navigation in and out of the tidal inlet, and allowing the tidal current between the ocean and the receiving body of water to keep the inlet scoured and open. There are 48 jetties on the open coast of Florida, none of which are in the Florida Keys. A groin is a structure designed for shore protection purposes. A groin is typically aligned perpendicular to the shoreline, or “shore normal.” The structures identified in the Permit as the NE Jetty and the SW Jetty are clearly groins, and not jetties. The mid-bulkhead is a groin, generally for shore confinement, with a channel-facing bulkhead. For purposes of continuity, the structures will be identified by the names given them in the Permit. Since there is negligible wave energy along the shoreline normal conditions, the groins have little or no day- to-day effect on longshore transport. Under storm conditions, the structures affect longshore transport, as evidenced by accretional “fillets,” and function as shoreline protection and confinement structures. The rock groins provide shelter, habitat and structure for corals, sponges, lobster, and fish in the area. The preponderance of the evidence demonstrates that the groins authorized by the Permit will have no adverse effect on fish and wildlife resources. NE Jetty The NE Jetty was originally constructed in the early 1960s, likely concurrent with the dredging of the navigational channel. The quality of the aerial photographs of the period make it difficult to tell if the NE Jetty was a loosely-placed rock embankment or a more well-designed and constructed structure. However, the fillet of sand accreted to the north of the Channel demonstrates that the jetty was in existence and functioning as a shore-protection structure. By the 1970s, the NE Jetty had become overwhelmed by longshore sediment transport from the northeast. Sediment overtopped the NE Jetty and filled in the landward reaches of the Channel. At that point, ability of the NE Jetty to perform as a shore protection structure was compromised to the point that it could no longer hold the shoreline out of the basin or the landward portion of the Channel. The Mid-bulkhead became the dominant structural control over the shoreline and started to accrete the shoreline to the northeast. At some time between 1977 and 1981, the Channel was maintenance dredged pursuant to a permit issued by the Department of Environmental Regulation, DEP’s predecessor agency. The NE Jetty appeared on the plans for the maintenance dredging. Thus, the most reasonable inference that can be drawn from the evidence is that the NE Jetty was repaired and restored in conjunction with the approved maintenance dredging. By 1981, the NE Jetty had been restored as the dominant shore protection structure north of the Channel, and a fillet of accreted material had been reestablished. The aerial photographs from that period are not sufficiently distinct to determine the precise size, shape, and configuration of the NE Jetty at that time. However, there is no evidence of additional work having been performed on the NE Jetty between 1981 and 1985. By 1985, the NE Jetty existed in substantially the size, shape, and configuration as it existed at the time of Hurricane Wilma. Between 1981 and the 2005 arrival of Hurricane Wilma, the evidence is convincing that the NE Jetty was holding up the shoreline to the northeast and preventing sediment from filling in the upper reaches of the Channel. Although the evidence suggests that the NE Jetty had, by 2005, begun to show its age, the continuous presence of an accretional fillet demonstrates that it continued to serve its function as a shore-protection structure. Although the NE Jetty suffered damage from Hurricane Wilma, it continued to perform its shoreline protection function. Aerial photographs taken in 2009 and 2011 show a relatively distinct structure with a well-defined accretional fillet. Thus, the greater weight of the evidence demonstrates that, at the time of its repair in May 2011, the NE Jetty was a functional groin. The NE Jetty, as repaired in 2011, is of substantially the same size, shape, and location as the structure depicted in aerial photographs taken in 1985, 2009, and early 2011. Although the elevation of the structure was increased over its pre-repair elevation, the increase was that reasonably necessary to prevent the function of the structure from being compromised by the effects of age and weather. The work performed on the NE Jetty, consisting of new rock laid on top of the existing rock, constituted repair and maintenance of the existing structure. Since 2005, and at the present time, the shoreline north of the NE Jetty has reached a state of equilibrium and stability, and is not expected to change significantly from its current condition. The preponderance of the competent, substantial evidence demonstrates that the effect of the NE Jetty on the shoreline and water resources of Grassy Key in the vicinity of the properties owned by Applicants and Petitioners is minimal and insignificant. The sand and sediment accreted to the north of the NE Jetty since 1981 is in the range of 250 square feet. SW Jetty The aerial photographs from 19647/ demonstrate that some form of structure then existed at the location of the current SW Jetty. The structure is indistinct due to what appears to be sidecast material from a small channel in front of the property to the immediate south of the Property. By 1971, the SW Jetty had become more distinct. From that time forward, the SW Jetty, and its accompanying fillet of accreted material, appears in roughly the size and shape of the structure as it appeared immediately prior to the arrival of Hurricane Wilma. The SW Jetty was heavily impacted by Hurricane Wilma. The overwash from the storm created a substantial runout alongside the SW Jetty, and the post-storm aerials suggest that the jetty boulders were undermined and shifted from their more uniform 2003 appearance. Immediately after Hurricane Wilma, the owner of the Property commenced restoration and repair activities. As part of the activities, the SW Jetty was repaired with the addition of boulders, which were often three feet and every now and then as much as four feet across. The boulders, being irregularly shaped, could not be stacked like Legos®, so the repairs were not neatly within the precise pre-Wilma footprint. However, the repaired SW Jetty was substantially in the length and location as existed prior to Hurricane Wilma, though it may have had a slightly wider cross-section. By 2007, the work on the SW Jetty was complete, and it had assumed its present appearance with the addition of a concrete cap. Its appearance -- i.e. length, width, and location -- in 2007 and 2008 was not dissimilar from its appearance in 2003. As repaired, the SW Jetty effectively constitutes the same structure that it has been since its initial construction. From a coastal engineering perspective, the work that was performed on the SW Jetty, consisting generally of new rock laid on top of the existing rock, constituted repair and maintenance of the existing structure. Dr. Lin testified that between 1974 and 2011, the area to the southwest of the southwest jetty was “about equalized,” though it was “accreting a little bit.” Thus, the effect of the SW Jetty on the shoreline of Grassy Key in the vicinity of the properties owned by Applicants and Petitioners from 1974 to 2011 was minimal and insignificant. Dr. Lin testified that, since 2011, the same area had eroded. The only substantive shoreline change that logically accounts for that subsequent erosion is the Mid-bulkhead extension, which is slated for removal under the terms of the proposed Permit. Petitioner testified that she observed no adverse effects from activities on the Property until after February 2011.8/ Since work on the SW Jetty was complete by no later than 2008, Petitioner’s testimony supports a finding that the SW Jetty has had no measurable effect on the water resources in the vicinity of the properties owned by Applicants and Petitioners. The preponderance of the competent, substantial evidence demonstrates that the effect of the SW Jetty on the shoreline and water resources of Grassy Key in the vicinity of the properties owned by Applicants and Petitioners is minimal and insignificant. Mid-bulkhead The structure of the Mid-bulkhead first appeared as part of the sidecast material from the excavation of the navigation channel in 1964. It coalesced into a defined but smaller and more rudimentary structure in the 1971-1972 time period. At that time, it was acting as the predominant shore protection structure due to the overtopping of the NE Jetty with sediment, which also filled in the landward reaches of the Channel. By 1981, after the maintenance dredging of the Channel, the Mid-bulkhead had assumed substantially the size, shape, and location that it has currently. The Mid-bulkhead has a navigation function of protecting the landward extent of the Channel from the collapse of adjacent sand and sediment, and a shore protection and compartmentalization function. Those functions have been consistent since 1981. The Mid-bulkhead appears to have been subjected to the overwash of sand and sediment from Hurricane Wilma, though it maintained its shape and form. The outline of the Mid-bulkhead appears to be more well-defined after the initial post-Wilma repairs. In any event, the configuration and size of the Mid-bulkhead is substantially the same as it had been since 1981. At some point, the interior section of the Mid- bulkhead was topped with soil that is inconsistent with that naturally occurring in the area. That fill was confined, and brought the Mid-bulkhead to a more even grade with the rock outline, but could have had no measurable effect on the shoreline and water resources of Grassy Key in the vicinity of the properties owned by Applicants and Petitioners. The preponderance of the competent, substantial evidence demonstrates that the effect of the Mid-bulkhead is minimal and insignificant. Channel In 1961, the Department of the Army authorized dredging of a navigation channel at the Property. The approved channel was to be 700 feet long, 30 feet wide, and to a depth of five feet below mean low water. The Florida Trustees of the Internal Improvement Fund issued a letter of no objection. By 1964, the Channel that is the subject of this proceeding had been dredged, though not to the 700-foot length approved. Rather, the Channel was dredged to a length of approximately 290 feet. Much, if not all of the dredge spoil was sidecast, creating a rock structure alongside the Channel. Measurements taken during the course of this proceeding demonstrate that the initial dredging resulted in near vertical side slopes, which shows that the bailing of the bedrock was accomplished to the limits. The width of the Channel is from 28 feet to 32 feet wide, which is within an acceptable tolerance of the 30-foot approved width. In 1976, the then-owner of the Property sought a permit from the DEP’s predecessor, the Department of Environmental Regulation, to maintenance dredge the Channel to a dimension of 290 feet long and 30 feet wide, to a depth of minus 8-feet mean high water, and to construct a new rock jetty to extend 230 feet waterward from the existing terminus of the NE Jetty. Given the mean tide range of 1.7 feet at the Property, the depth of the proposed dredging would have been minus 6.3 feet mean low water, or 1.3 feet deeper than originally approved. The permit drawings depict the existing NE Jetty, the Channel boundary, the outline of the Mid-bulkhead, and the sidecast rock structure alongside the southern side of the Channel. The permit was denied. In 1977, the owner of the property reapplied for a permit to maintenance dredge the Channel to a dimension of 290 feet long and 30 feet wide, and to a depth of minus 4.0 feet below mean low water nearshore to minus 6 feet below mean low water at the waterward end. The proposal to construct an extension of the NE Jetty was deleted. The permit was issued, and a severance fee for the dredged material was paid based on a projected 700 cubic yards of material removed. The permit drawings and photographs depict the existing NE Jetty, the nearshore Channel boundary, and the general outline of the Mid- bulkhead. By 1981, aerial photographs demonstrate that the maintenance dredging of the Channel was complete, the NE Jetty was in place and functioning to protect the shoreline as evidenced by the accretional fillet, and the Mid-bulkhead had assumed its approximate current shape and configuration. Although the Channel has varied in depth over the years since the maintenance dredging and Hurricane Wilma, the greater weight of the evidence, including photographic evidence, indicates that the Channel was well-defined and remained navigable during that period. The Channel is an open-water exposed channel. Water in the Channel mixes due to direct tidal flow and the sheet flow of water due to shear wind stress. As water passes over the Channel, it sets up gyre, which is a mixing process. The open- water exposed Channel is subject to a high degree of mixing, even on normal waveless conditions, because of the wind transport of water and the tidal transport of water. The Channel is not a semi-enclosed basin. A semi- enclosed basin does not receive the direct forcing functions that an open-water channel receives. A semi-enclosed basin has no direct connection to open waters, but is connected to open waters by a narrower opening. Although a semi-enclosed basin exchanges water via every tidal cycle, the flushing process is one of slow mixing, in which a little bit of water is added to and withdrawn from the larger basin through the narrow opening during each tidal cycle. In such a case, a flushing analysis may be necessary to determine how much time and how many tidal cycles it may take to effect a complete exchange of the water in the semi-enclosed basin, and thus, for example, to dilute a pollutant to an acceptable level. A flushing analysis is not needed in this case because the Channel is an open-water, openly-exposed location subject to a high degree of mixing under normal day-to-day tidal processes. There is no greater basin connected by a restricting connection as with a semi-enclosed basin. Rather, the Channel has direct exposure to the tides, along with wind shear stress moving the water. The evidence in this case is substantial and persuasive, because the Channel is highly exposed to the open water and the tides, and a well-mixed and well-flushed aquatic system, that a flushing analysis is neither required nor necessary. Dock The dock made its first obvious appearance in 1981. It appears in a consistent shape and appearance through 2011. Aerial photographs taken in 2012, after the maintenance dredging of the Channel was conducted, show the dock had been removed. At the time of the hearing, the Applicants had installed new pilings and vent boards for the replacement dock, but the decking had not been installed. Work to complete the replacement of the dock was halted due to the pendency of the litigation challenging the structures. The proposed dock is less than 500 square feet. It is proposed for non-commercial, recreational activities. It is the sole dock proposed on the Property. The proposed dock will not impede the flow of water or create a navigational hazard. Boat Ramp Since the issuance of the 2008 approval, the boat ramp site was graded and stabilized in limerock material. The concrete ramp was not completed due to the pendency of the litigation challenging the structures. However, Applicants propose to pave the ramp with concrete. Based on Mr. Clark’s observations during his site visits, the boat ramp is landward of the mean high waterline depicted on the survey. The preponderance of the evidence demonstrates that the proposed boat ramp will provide access to the Channel, which provides a minimum navigational access of two feet below mean low water to the ramp. Applicants have agreed to install depth indicators at the ramp to identify the controlling depths of the navigational access. The work on the ramp involves no seagrass beds or coral communities. The ramp as proposed will require no more than 100 cubic yards of dredging. The total width of the ramp is to be 20 feet and the ramp surface will be no wider than 12 feet. Beach Area The area between the SW Jetty and the Mid-bulkhead is an accreted beach-type area that has been confined and protected by the Mid-bulkhead and the SW Jetty. The shoreline landward of the mean high water line, from the dry beach and to the upland, is somewhat steeper than adjacent unprotected shorelines, which is indicative of the grooming of the upper beach sediment and the stability of the shoreline between the Mid-bulkhead and the SW Jetty. As a result of the Hurricane Wilma storm surge, a substantial amount of sediment was swept across the Property and into the Atlantic waters. The beach area was inundated with sand and sediment from the overwash, which appears to have moved the shoreline well waterward of its previous position. Along the northern side of the SW Jetty, a substantial channelized gully was created. The configuration of the shoreline post-Wilma suggests that efforts were made by the then-owner of the Property to fill in the gully on the northern side of the SW Jetty, and to groom and restore the shoreline by redistributing sand and sediment on the Property. It is typical, and allowable under DEP emergency final orders, for affected property owners to redistribute overwashed deposits and place them back within the beach system. In that regard, the DEP encourages the redistribution of clean beach sand back onto the beach. The then-owners of the Property were not alone in taking steps to address the effects of Hurricane Wilma on their adjacent shorelines. The photographic evidence demonstrates that Petitioners engaged in similar restorative activities, which included bringing in material purchased from a contractor to fill in a gully created on their property by the overwash. Observation of representative soil samples from the beach area demonstrate that the soils are consistent with those in the upper beach areas found throughout the area. The only areas of inconsistent soils were found in the interior of the rock structure of the Mid-bulkhead, which contained a four to six-inch layer of soil with a different consistency and darker brown color, and small area of similar soil directly adjacent thereto and well above the mean high water line. The greater weight of the competent, substantial, and credible evidence demonstrates that there was no substantial amount of “fill” from off-site placed on or adjacent to the beach area. Rather, the nature, appearance, and composition of the soils suggests that the temporary increase in the size of the beach area after Hurricane Wilma was the result of grooming and redistribution of sand and sediment pushed onto the Property and into the nearshore waters by the Hurricane Wilma storm surge. In the years since Hurricane Wilma, the influence of normal tidal and weather-driven events has returned the beach area between the mid-bulkhead and the SW jetty to roughly the configuration that existed prior to the passage of Wilma, though it remains somewhat waterward of its pre-Wilma location.

The Issue Whether the Southwest Florida Water Management District should issue the Individual Environmental Resource Permit (the "Individual ERP," the "ERP" or the "Permit") applied for by Entryway Developers, LLC ("Entryway")? The ERP was preliminarily issued by the District as Draft Permit No. 43024788.000 (the "Draft Permit"). If it becomes final, it will allow Entryway's successor in interest, Westfield Homes of Florida ("Westfield") both to construct a new surface water management system in service of a proposed subdivision, known as Ashley Glen, in southern Pasco County, and to conduct dredge and fill activities on site.
Findings Of Fact The Parties The Petitioner in this proceeding is Dr. Octavio Blanco. A veterinarian, citizen of Florida and a resident of Pasco County, he holds a property interest (described below) in property immediately adjacent to Ashley Glen. One of the three Co-Respondents, the Southwest Florida Water Management District (the "District" or "SWFWMD") is a public entity created by Chapter 61-691, Laws of Florida. It exists and operates under Chapter 373, Florida Statutes (the "Florida Water Resources Act of 1972" or the "Act"). The District is the administrative agency charged with the responsibility to conserve, protect, manage and control the water resources within its geographic boundaries. It does so through administration and enforcement of the Act and the rules promulgated to implement the Act in Chapter 40D, Florida Administrative Code. Entryway, the second of the three Co-Respondents, is a limited liability company and the original applicant for the Permit. Westfield, the third of the Co-Respondents, is a Florida general partnership and the current owner of the Ashley Glen Project. If the Permit is issued by way of a final order, Westfield will be the permit-holder. An application for an Individual ERP must be signed by the owner of the property or the owner's authorized agent. If signed by an agent, a letter of authority must be submitted by the owner. See Fla. Admin. Code R. 40D-4.101(2). Westfield was not the owner of the property on the site of the Project at the time of the filing of the application. Entryway was the owner. Westfield filed with DOAH a letter of authority received from Entryway.2 The letter authorized Westfield to sign the Individual ERP application. Ashley Glen and the Blanco Property "Ashley Glen-Villages 2-5" ("Ashley Glen" or as it is referred to in the Draft Permit, the "Project") is a 266.36-acre residential subdivision planned to be divided into more than 400 lots. Located in southern Pasco County, the subdivision is on the north side of State Road 54, approximately three miles west of US 41 and less than 1000 feet east of the Suncoast Parkway. To the north, Ashley Glen is bounded along an abandoned railroad right-of-way. The right-of-way extends beyond the northwest and northeast corners of the property in both easterly and westerly directions. There are 72.69 acres of surface waters and wetlands on the Ashley Glen site. Among the 19 isolated and contiguous wetlands on the property is a portion of a Cypress-forested wetland system (the "Cypress-forested Wetland"). The Cypress-forested Wetland was described at hearing by one of Westfield's experts as "a large wetland" (tr. 41) that is typical of the area. As with similar wetland systems throughout the state, the Cypress-forested Wetland undergoes "seasonal drawdowns and dry-outs, and in the wet season . . . flood[s] out to the edges and even beyond in certain storm events." (Tr. 43). The portion of the Cypress-forested Wetland that is on the Ashley Glen site is identified by the Permit as "Wetland A3." Wetland A3 is 29.94 acres. The entire Cypress-forested Wetland system south of the railroad bed of which Wetland A3 is a part is at least twice as large. Most of the remainder of the Cypress Wetland south of the railroad right-of-way is on the Blanco Property. It appears from exhibits used during the hearing that the Cypress Wetland originally extended north of where the railroad right-of-way now lies in its abandoned state. The connection was indicated also in the testimony of Mr. Courtney (Westfield's "wetlands" and "ERP" expert3) when he stated that there was potential for contiguity with systems to the north. Aerial photographs used at hearing indicated that the Cypress- forested wetland system was, indeed, part of the contiguous wetland system to the north of the railroad bed. The contiguity between the Cypress-forested Wetland and the system to the north was confirmed by Dr. Baca, Petitioner's wetland ecologist, on the basis of on-site examinations. Dr. Baca believes the Cypress-forested Wetland to be part of a much larger system that extends northward and to the west and that is contiguous with the Gulf of Mexico. He determined that despite the establishment of the railroad bed, the Cypress-forested Wetland remains connected to the contiguous wetland system to the north by way of pipes under and through the bed. Drainage on the Ashley Glen site is primarily from south to north with significant contribution from a drainage basin to the east. Drainage from the south is channelized by a ditch that runs nearly the length of the property from Wetland C12 at the southeastern tip to Wetland A3 near the site's northern boundary. Drainage from the eastern basin toward Wetland A3 is intercepted by the ditch. The result is that the drainage from the east is captured before it reaches Wetland A3 and drainage from the south bypasses Wetland A3 to be discharged northward at the railroad bed so that all of the drainage is "short-circuited by [the] ditch to the actual discharge location of [Wetland] A3." (Tr. 41). The discharge location from Wetland A3 was more precisely described at hearing by Mr. Courtney as "the confluence of [Wetland] A3 and the railroad bed where [the ditch] discharges off-site flows and [the] easterly to westerly flows into pipes that go under [the] old railroad bed " (Tr. 40-41). This testimony supports Dr. Baca's confirmation of the connection between the Cypress-forested Wetland and the contiguous wetland system north of the railroad bed. To the west of the ditch and the Ashley Glen site is the Blanco property. It has been held by Dr. Blanco's family for a period spanning six decades. Its boundaries roughly form an elongated narrow rectangle. From the eastern and western ends of 400 feet of frontage on State Road 54 (the southern boundary of the Blanco Property) the eastern and western boundaries run parallel of each other approximately 8000 feet to the north where the northernmost boundary of the Blanco Property meets the abandoned railroad right-of-way. The majority of the northern half of the Blanco Property is in the Cypress-forested Wetland. In addition to the drainage from the south and the east received prior to the digging of the ditch, the wetland receives drainage from the west which traverses the property between the Blanco Property and the Suncoast Parkway. With the exception of one acre on which sits the house in which Dr. Blanco's mother lives, the Blanco Property is presently the subject of a Land Trust Agreement. Through this unrecorded instrument, dated December 19, 1996, Dr. Blanco has an ownership interest in the property. Dr. Blanco's concern for the property pre-dates his ownership interest conferred by the trust agreement. He lived on the property from the age of three until he left for college. During that time, he "constantly" (tr. 374) observed many species of wildlife in the Cypress-forested Wetland, as he explained at hearing: Starting with mammals, I observed many deer, foxes, coons, coyotes, squirrels, ground squirrels, fox squirrels. And then numerous bird species . . . from the sandhill cranes to various storks and herons and egrets and . . . [m]ostly aquatic birds . . . many hawks [and] an occasional eagle [as well]. A lot of animals, such as frogs and snails. The apple snails particularly I've noticed. I've always admired them and the way they lay their eggs up on the water line. So, I've noticed them for years out there [along with] [m]any snakes [and], alligators. Id. Over the years, Dr. Blanco has observed changes, especially among the wading birds and the aquatic species: You see less and less of them. The periods where there's consistent water to support their life has grown shorter as time goes by. And this time of year where there's water, the life is pretty abundant. But then, in recent years, I've noticed that the time period seems to be getting shorter and shorter. And then . . . when I go out there, I use all my senses, not just my eyes, and the place just sounds different when it's full of life versus when it's, essentially, dried up. (Tr. 374-375). Just as in any typical cypress-forested wetland, during wet periods, the cypress trees in the Cypress-forested Wetland "will be inundated and the ground will be saturated to the edge of the uplands." (Tr. 45). During these times, the majority of the storms that deliver rain are considered small, that is, rainstorms of below half an inch. Much bigger storms, of course, also contribute to the water that stands in the wetland from time to time. "By the same token, in droughts or dry seasons, the water levels . . . typically drop to at or below the ground level." (Tr. 46). The dry periods, if part of the natural cycles between hydro-periods, contribute to the health of the system. For example, during dry periods nutrients are oxidized, one of the functions of a wetland. In 2002, the Cypress-forested Wetland was dried out from mid-March at the end of the dry season until the end of July, a period of drought. The dry season and the occasional drought contribute, of course, to a lowering of the water table below the surface of the wetland. But the water table may also be lowered by the pumping of water from wellfields in the area, one to the northwest of the site, another to the southeast. That pumping is monitored by the District. The District takes action to minimize damage from any lowering of the water table caused by pumping water from the wellfields. Apple snails have been recently observed in the Cypress-forested Wetland. "Apple snails are unique in that they're the sole food of the snail kite, an endangered species." (Vol. III, p. 61). There are snags and dead trees in the Cypress-forested Wetland as well. Used by many birds and mammals, they provide particularly good habitat for woodpeckers. The Cypress-forested Wetland is not a pristine wetland. The establishment of the railroad bed had an impact. In its abandoned state, the railroad bed continues to have an influence on its discharge to the north. The Suncoast Parkway "might have had some impact." (Tr. 53). Cattle grazing on both the Blanco Property and the Ashley Glen site has had an impact on the herbaceous ground cover layer and on the wetland's water quality although it is unlikely that the cows grazed in the Cypress-forested Wetland. ("Generally, [cows] don't graze on . . . wetland plants, because they're either bitter tasting or [have] poor textures . . . .") (Vol. III, p. 58). The well- fields in the area have had historic impacts mitigated, as mentioned, through implementation of an area-wide hydrology restoration plan by SWFWMD. The most significant impact to the Cypress-forested Wetland resulted from the combination of the construction of State Road 54 and the ditch's channelization of stormwater runoff migrating through the center of the Ashley Glen site. Had the property not been ditched, the stormwater runoff and any other migrating water would have been conveyed by sheet flow into the Cypress-forested Wetland. Despite the varied impacts over the years, the Cypress-forested wetland remains ratable today "as a mid to higher level quality wetland for the area." (Tr. 43). The Draft Permit Application for the permit was submitted on February 7, 2003. After eight formal submittals of information in response to questions by the District, a Draft Permit was issued on December 16, 2003. The Draft Permit lists the "Project Name as Ashley Glen - Villages 2-5" and otherwise refers to Ashley Glen as the "Project." The Permit allows the Project to fill 43.75 acre-feet of the 100-year flood plain on the Ashley Glen site. At the same time, the Permit allows 51.98 acre-feet of excavation on- site. Project construction will result in the filling of 1.61 acres of forested and non-forested wetlands and secondary impacts to at least one of the isolated wetlands. The permit speaks to secondary impacts to another of the wetlands and surface waters on-site and finds that there are none: "[O]ne isolated wetland, 0.37 acre in size, and 2.81 acres of surface waters will be impacted, however, since these areas provide no significant habitat functions, no habitat mitigation will be required." District Ex. 5, pgs. 3-4. The mitigation for the impacts that require mitigation, in the District's view, includes creation of 2.89 acres of wetlands and preservation of 65.32 acres of wetlands. The Permit also authorizes the construction of a new surface water management system (the "SWM System") to serve Ashley Glen. The Surface Water Management System The SWM System consists of six wet detention ponds, four isolated wetland treatment systems, an attenuation pond, and an associated conveyance and discharge structure. The wet detention ponds and the isolated wetland treatment systems were designed in accordance with Section 5.2 of the District's Basis of Review. Westfield Ex. 6 depicts the "generalities of the [SWS] [S]ystem in [Ashley Glen's] built environment." (Tr. 56). Key pipe areas are shown in white on the exhibit. For example, the existing ditch is re-located slightly to the east; the exhibit shows in white where water is piped from the northern terminus of the new, re-located ditch into Pond P11. This piped water will consist of drainage from the south that is now conveyed by the existing ditch and drainage from the east that passes through Wetland W2 and Wetland W1. In keeping with the historical drainage pattern that preceded the existence of the ditch, drainage from the basin on the eastern part of the property that passes through Wetland F4, Wetland E4, and Wetland D5 will also be discharged westward into P11 to be discharged at a point toward the southernmost part of Wetland A3, the wetland's headwaters. The discharge from P11 was described by Mr. Courtney at hearing: The discharge of P11 was placed up in the headwaters of A3 [where] . . . the [existing] ditch short-circuited the discharge of . . . waters to the discharge point of A3. [An SWM System] . . . control structure is placed at the headwaters of A3, a much better situation for A3, given that the quantities and quality of water is going to be the same or better, because water is now going to be reintroduced to the headwaters of A3 as opposed to short- circuiting it. (Tr. 57). Mr. Courtney estimated that one-fourth to one-half of the surface water flows on the property coming from the south and the east were routed unnaturally by the ditch to Wetland A3's discharge point at the railroad right-of-way at the northernmost point of the wetland. The project re-routes these waters to a point near the headwaters of Wetland A3 (in its southernmost part). Surficial flow, therefore, that had by- passed Wetland A3 because of ditching will be routed by the SWM System to the headwaters of Wetland A3 after treatment and attenuation provided that the attenuation pond reaches a high enough elevation. Any water discharged to Wetland A3 from the attenuation pond will flow in a northerly direction (the historical flow pattern) through the wetland to the point of discharge at the railroad bed. Provided that the restored flow is of good quality, restoration of the hydrology is a benefit to the system. On this point, Dr. Baca agreed with Mr. Courtney. The Cypress-forested Wetland on the Blanco Property and the wetland system that extends north of the railroad bed "are dependent upon the treatment, the care and the protection afforded the wetland on the Ashley Glen property." (Vol. III, pg. 60). Wetlands B8 and D3, surrounded by developed lots, are served by detention ponds. Internal drainage from the lots is collected from street systems. Pop-off from the systems goes either directly to a detention pond and then a wetland or to a sump and then to a wetland. After treatment, the drainage is conveyed to Pond P11. Pond P10, a relatively small detention pond, is situated at the headwaters of Wetland A3. The pond treats runoff and flows into Wetland A3. Pond P11, although not a stormwater detention pond and for which the applicant receives no treatment credit, is nonetheless "a good backup treatment mechanism for stormwater that is meeting state water quality standards as discharged from all of the drainage systems in the uplands." (Tr. 59). Through the attenuation process, moreover, it will perform some treatment that meets or exceeds the minimal requirements of ERP permitting. After attenuation and whenever the pond reaches a certain elevation, waters are discharged into Wetland A3. A major point of focus of Dr. Blanco's case is the excavation of the attenuation pond and its interaction with Wetland A3. The attenuation pond is designated in the Draft Permit as Pond P11 ("P11"). P11 If excavated according to present plans, P11 will be 25 feet deep at its deepest point (less than one percent of the pond). "[T]he deepest areas run along the corridor that goes between [Wetlands] B6 and D5." (Tr. 166). The shallowest areas of P11 are along the western edge of the pond where a shelf will be constructed. The surface area of the pond will take up approximately 40 acres. (See endnote 4). The Respondents refers to P11 as a "100 year flood plain compensation area." (Tr. 116). The Permit's "Water Quantity/Quality list of ponds denominates P11's "treatment type" as "[a]ttenuation" which would make it an attenuation pond. Dr. Blanco prefers to call P11 a borrow pit asserting that one reason for its excavation is to obtain fill for the development. Dr. Blanco's labeling of P11 as a borrow pit appears to be correct since the District referred to it as a borrow pit and since significant dredging on site is allowed by the Draft Permit. Whether Dr. Blanco's and the District's nomenclature for P11 is accurate or not, there is no dispute that P11 is part of the stormwater management system. The Draft Permit ascribes to it the function of attenuation: the process by which flow is slowed that allows compounds to be reduced in concentration over time. It is a significant component of the SWM System. Conveyance of water of sufficient quality that has undergone attenuation from the pond into a point near the headwaters of Wetland A3, moreover, poses the potential to improve the wetland's hydrology. Dr. Blanco asserts that fill needed by the Project could be obtained off-site. In other words, P11 does not need to be excavated to obtain the fill. But obtaining fill material is not the only purpose of P11 since it also provides retention and attenuation functions. Dr. Blanco's main concern with P11, however, is not its status as a borrow pit. His concern is based on three of its characteristics, the latter two of which relate to its nature as a borrow pit: 1) its placement, excavated directly adjacent to Wetland A-3; 2) its depth, at its deepest point, 25 feet; and 3) its size; close to 40 acres in open surface area.4 Due to sheer size of P11's open surface area, significant volumes of water in P11 will be lost routinely to evapo-transpiration. When the water level in P11 is below the water level in Wetland A3, moreover, the pond will draw water out of the Cypress-forested Wetland. Whenever the water is below its control elevation, it will take a considerable volume of water to raise it to the elevation appropriate to protect Wetland A3 and the rest of the Cypress-forested Wetland. Reaching the control elevation will occur only when all available storage has been filled and contributions of water (from rainfall, stormwater run-off, or by way of conveyance through the SWM System or otherwise) exceed loss through evaporation and seepage, downward and lateral. The parties disagree as to whether the applicant has provided the assurances necessary to justify issuance of the Permit. The most contentious point is about the effect P11 will have on Wetland A3 and the extended Cypress-forested Wetland. Westfield (with the support and concurrence of the District) bases its case for assurances, in the main, on a type of computer modeling. Dr. Blanco, on the other hand, presented testimony that criticized the computer modeling that was done in this case in support of the application. That computer modeling is known as "Interconnected Pond Routing" or "ICPR." ICPR Interconnected Pond Routing ("ICPR") is a type of hydrological computer model that takes into account surface water flows. It does not take into account groundwater flows, downward or lateral seepage or the lowering of the water table by well-field pumping. It models the surface water hydrology of a site as it might be affected, for example, by detention basins and channel pipes. It models pre-design of a site to be developed and then post-design of a site prior to actual development to provide comparative analysis. It is also a predictive tool. As with any predictive tool, its accuracy can only be definitively determined by observation and collection of data after-the-fact, in this case, after development. ICPR modeling is used in particular for stormwater and surface water management systems. For that reason, it was used by Westfield to support the ERP application in this case. Before ICPR modeling of the Ashley Glen site and the surrounding area was conducted, topographic information was collected by survey. The results of the survey and the modeling that followed resulted in several of the exhibits used by Westfield at hearing. For example, the topographic information and ICPR were used to produce a post-development map (Westfield Exhibit 12). In addition to sub-basins reflected in Westfield Exhibit 11 that relate to the hydrology of the site the map shows two pods (a "Southern Pod" and a "Northern Pod") of development. Approximately 400 feet of the Southern Pod will abut Wetland A3 on the pod's western edge. The location of the Southern Pod will necessitate re-location of the existing ditch. The Northern Pod, in contrast, will be separated from Wetland A3 by both P11 and the proposed road. The Northern Pod, the larger of the two proposed pods of development, is farther from Wetland A3 although it is separated from Wetland C2 solely by the proposed road. The sub-basins on Westfield Ex. 12 are reflected in Westfield Ex. 11, the result of pre-design modeling that revealed three off-site basins composed of 218, 544 and 908 acres. Each sub-basin corresponds to a detention pond designed to assist in enhancing the site's post-development hydrology. The modeling was also used to introduce P11, Westfield's proposed 100-year flood compensation area that would act as a detention pond for attenuation. Each sub-basin used in the modeling exercises covers an area for which there is information relative to size, curve number and time of concentration, all of which was entered into the modeling. Kyle Cyr, a registered P.E. in the State of Florida, and an expert in ICPR and stormwater modeling, described at hearing what happened next: The input is then directed towards a node, which we call the wetlands of the node or detention ponds. And then each node is interlinked by either channels, pipes or weirs, swells, drop structures. * * * [W]e check the models for pre and post to make sure there's no adverse impacts to off- site properties. No additional flows are allowed to leave the site. * * * We end up with flows, staging elevations for each node. . . . [The result is] [a] drainage report. [The] drainage report has a pre- and post- analysis in it. * * * [The] drainage report [is used] to design the site, to design the elevations and grading of the roads and [then] the lot and culvert sizes. (Tr. 147, 148). The drainage report and the information with regard to the design was then submitted by Westfield to the District together with a "pond wetland hydrology interaction report" and modeling with regard to "several minor storm events, a one-inch, a two-inch and a mean-annual event run . . . like a normal rainfall in the area." (Tr. 150). Various hydrographs for storm events were prepared by Westfield. In general, storm events should assist the hydrology of Wetland A3. The SWM System poses the potential that in storm events, P11 will discharge water to Wetland A3. The discharge pre-supposes that P11 will be at an appropriate elevation to allow the discharge with the addition of the surface water conveyed by the system into the pond. Hydrographs of the time versus inflow into Wetland A3 for pre-development and post-development conditions for the storm events were prepared by Westfield. For the one-inch storm and the mean-annual events, provided the pond is at an appropriate elevation prior to the storm (a proviso applicable to all of the hydrograph information), it is reasonably expected that there will be slight increases in peak flow after the development than before. For the two-inch storm, it is reasonably expected that there will be a slight drop in peak flow. None of the changes should have a negative effect on Wetland A3 so long as P11 maintains appropriate water elevations so that water has not been drawn out of the wetland that would have sustained the wetland had P11 not been excavated.5 Hydrographs that depict expected volume over a 72-hour time frame were also prepared based on the same storm events. During the applicable time frame for two-inch and mean-annual events, it is reasonably expected that there will be a slight increase in the volume of water entering Wetland A3 after development. As the result of a one-inch storm event, it is reasonable to expect there to be a slight decrease in volume over the 72 hours. None of the changes are expected to have a negative effect on Wetland A3, again, provided that appropriate water elevations are maintained in P11. Finally, hydrographs were prepared for time-versus- inflow for 25-year and 100-year storm events both pre- development and post-development. The modeling showed that, after development, "[a]djacent properties will not experience the higher flood level [that] they have in the past." (Tr. 156). The decrease is due to the holding back of water in detention ponds after development that will flow off at a slower rate than under pre-development conditions. The hydrographs show the difference in water flowing onto the site and Wetland A3 after the development under typical conditions in comparison to before development is slight. Water levels in Wetland A3 at times of typical storm events, after development, therefore will not be affected in any meaningful way by the SWM System so long as P11's water level is maintained at an appropriate elevation. In accordance with Section 4.2 of the District's Basis of Review, the SWM System is designed so that "[o]ff-site discharge is limited to amounts that will not cause adverse off- site impacts." Section 4.2 of the Basis of Review. See District Ex. 4, CHAPTER FOUR, pg. 1. The allowable discharges from the Project were established as a pre-development peak discharge rate from a 25-year, 24-hour storm. The modeling showed that the post-development discharge rates do not exceed the pre-development peak discharge rate. The ICPR modeling did not consider the outfall from Wetland A3 that occurs at the abandoned railroad right-of-way on the northern end of Wetland A3. As explained by Mr. Cyr, "Wetland A3 is . . . [a] boundary condition. That's where our model stops." (Tr. 198). The structure at the outfall at the northern end of Wetland A3 consists of three 42-inch pipes. Had the outfall been considered, Mr. Cyr testified, it would have had no effect on the results of the modeling. The understanding of the effect on the hydrology of the site provided by ICPR modeling conducted by Mr. Cyr, the drainage report and the other aspects of the information (such as the hydrographs and the design and information related to water quality) gathered and produced by Westfield support the District in its decision to issue the Permit. But there is a criticism of the modeling. It was presented by Dr. Blanco's witness: Mr. Vecchioli, an expert in hydrology as it relates to groundwater. The Site's Hydrogeology The area in which Ashley Glen, the Blanco Property and the Cypress-forested Wetland sit was described by John Vecchioli, a licensed geologist in Florida and an expert in hydrogeology, as: a low-lying plain of limited altitude . . . underlain by some 20 to 50 feet of . . . fine to very fine sand, sometimes silty, sometimes containing a clay layer or two. And then beneath that blanket of sand is . . . the upper Floridan [A]quifer, . . . a thick deposit of limestone, which also constitutes the primary source of drinking water for the area. (Tr. 93). Connected with the surface waters of the area so that the aquifer and the surface waters function as a single system, the Floridan Aquifer in Pasco County is known as a "leaky- confined aquifer." Id. Its "leaky-confined" nature means that: [The Floridan is] not firmly capped by thick layers of clay, but rather by sand deposits that although . . . more pervious than the layers of clay, still impede the exchange of water between the two systems. Id. The source of the water in the upper Florida Aquifer is mainly rainfall because the Aquifer "intercept[s] waters from the surface." (Vol. III, Tr. 95). Much of the water in the upper Floridan is recharged, "very young water . . . indicating that it has a good connection with the surface." Id. The interaction between the surface water and ground water was shown by a study that "showed . . . 93% of the water derived from . . . public supply wells [was] primarily from capture of water from the surface environment." (Vol. III, Tr. 94). Furthermore, "[t]here's some 133 million gallons per day pumped from a combination of wellfields in [the] area [of Ashley Glen and the Blanco Property]." Id. The documented adverse impacts of the pumping in the area has been limited to "drying up the surface, capturing water from streams, pulling down . . . wetlands." Id. The interaction between the surface waters and groundwater in and around Ashley Glen leads to Mr. Vecchioli's opinion that the effects of the SWM System on groundwater, and in particular the effect of Pond P11, "is a very important aspect . . . almost totally ignored [by Westfield and the District.]" Id. In other words, ICPR, because it does not account for effects on groundwater, is a flawed model for determining the impact on all water resources in the area. It did not consider "downward leakage as a means for water to escape from the pond [P11]." (Vol. III, p. 96). The omission is critical because the Floridan aquifer system has a potentiometric surface that's some 10 to 20 feet lower than the water table or surface environment most times during the year. The meaning of this was explained at hearing by Mr. Vecchioli: [T]here's a downward gradient where water will flow from the land surface in the vicinity of Pond 11 [Pll] down into the Floridan. When [Westfield's consultants] did the evaluation of the wetland-pond interaction, they ignored this. They essentially said that because we don't intend to penetrate the confining layer, which SWFWMD does not want done, that there won't be any leakage out of the pond vertically. This is not correct . . . . [I]n creating the pond . . . 25 feet or roughly half of the confining bed, or a greater amount, [will be removed], so this makes it much easier for water to move from the water table at land surface down into the Floridan . . . . Id. The failure to account for downward leakage or "vertical seepage" is significant. "[I]t . . . creates the uncertainty as to whether P11 is going to receive enough water to stay saturated to the top for much of the year." (Vol. III, Tr. 96- 97). If the water level in P11 does not stay at the control elevation, "there will be a downward gradient that prevails from the adjacent wetland [Wetland A3] into the pond and part of this will leak out into the Floridan aquifer, in addition to additional water lost by evaporation from the open surface of the pond. [This] . . . will create a deficiency in storage for the pond." (Vol. III, Tr. 97). Furthermore, with the removal of the sand during excavation and the replacement of it with water, "the material the water [that is contributing to seepage] has to move through is less, so you have much less energy lost to frictional forces." (Vol. III, Tr. 115). The result is that vertical seepage will be more likely to occur after the pond is excavated than before. In other words, it will be much easier for water to move from the surface into the Floridan. The seepage, moreover poses difficulties in maintaining elevation in P11. Evaporation from the pond will be greater than evaporation from the wetland. If water in the pond is not at the appropriate elevation, water will be drawn from Wetland A3. The wetland will be drier than under natural conditions. Mr. Vecchioli stopped short of predicting that downward leakage would damage the wetland; he stated only that damage would occur if P11 functions as he thought it "might." (Vol. III, Tr. 106). In essence, Mr. Vecchioli's opinion does not stand as a projection of certainty that the wetland will be damaged. Instead, it presents a factor that was not considered by Westfield in its analysis and by the District in its review. The District counters Mr. Vecchioli's opinion with the fact that the depth of the excavation is in compliance with the District's Basis of Review and that it will not remove what SWFWMD considers to be a "primary retarding material or section," that is, a layer of clay. But it will remove much of the sand. Sand, while it inhibits downward seepage from the surface into the aquifer, is nonetheless not impermeable; it is not an aquitard. Seepage, therefore, will occur despite compliance with the Basis of Review (as explained, below) with regard to depth of excavation and aquitards. Depths of Excavation and Aquitards Subsection 6.4.1.b of the Basis of Review addresses depths of excavation: 6.4.1 Dimensional Criteria (as measured at or from the control elevation). * * * b. Depth - The detention or retention area shall not be excavated to a depth that breaches an aquitard such that it would allow for lesser quality water to pass, either way, between the two systems. In those geographical areas of the District where there is not an aquitard present, the depth of the pond shall not be excavated to within two (2) feet of the underlying limestone which is part of a drinking water aquifer. District Ex. 4, CHAPTER SIX, Pg. 2 The term "aquitard" is not a term that appears in the "Explanation of Terms" section of the Basis of Review. See District Ex. 4, Section 1.7, CHAPTER ONE, pgs. 2-6. The District does not consider sand to be an aquitard. Clay, on the other hand, is an aquitard. As explained by Mr. Ritter at hearing, the term aquitard is "defined as a somewhat impermeable layer that if you were to cut through that, that would be considered a breach." (Vol. III, Tr. 128). If the District were to consider sand an aquitard, there is nowhere in the District that a pond could be excavated in compliance with subsection 6.4.1.b of the Basis of Review. The Ashley Glen proposal for the excavation of Pond P11 to a depth of 25 feet complies with the Basis of Review. The depth of excavation of the pond does not come within two feet of the underlying limestone. Nor does it breach a clay layer or any other aquitard. Compliance with the "depth of excavation" and "aquitard" provisions of the Basis of Review does not cure the problem with the placement of Pond P11: adjacent to Wetland A3. The problem was addressed (although not resolved) by a post- Draft Permit correction that showed more water reaching Wetland A3 by way of the SWM System than had been shown in the original modeling. Post-Draft Permit Correction The modeling described at hearing included a correction after the issuance of the Draft Permit. The correction was made because of "an additional off-site contributing area east of the project that was not considered in the original flood study prepared by the [applicant's] consultant . . . ." (Tr. 222). The model was updated to incorporate the additional contributions that had not been considered prior to the issuance of the Draft Permit. After the additional data was introduced, the modeling suggested changes that Westfield made to its proposal. On the north end of the Project, a conveyance channel had to be enlarged. Additional culverts were proposed beneath the proposed roadway to reduce flood impacts from the additional flows entering from the east that had been overlooked. Further evaluation by the District ensued in the wake of the additional modeling. Ultimately, in the process that preceded the final administrative hearing, the application was determined by the District to "still me[e]t the conditions for issuance and [staff, therefore] recommended approval." Id. In other words, this additional water would not cause too much water to flow into Wetland A3 and cause adverse impacts from flooding. The additional data demonstrates that there will be more water flowing through the SWM System and into Wetland A3 then originally projected but not too much so as to cause adverse flooding impacts. The additional water, however, does not cure the problem that Pond P11 poses for Wetland A3 as explained by Mr. Vecchioli due to the wetland's location, depth and open surface area. Location, Depth and Open Surface Area In the final analysis, while there may be nothing out of compliance technically with the depth of P11 and the size of its open surface area, when these factors are combined with the location of P11, adjacent to Wetland A3, there is a problem: the potential for adverse impact to Wetland A3 and the extended Cypress-forested Wetland of which it is a part. Seepage and evaporation will make it difficult to maintain the water levels in P11 necessary for the pond to discharge into the wetland. Furthermore, when the water table is down, whether due to drought, pumping activities in the region or for some other reason, and P11 is not at an appropriate elevation, it will draw water out of Wetland A3. Seepage and evaporation have the potential to exacerbate the drawdown. Seepage promoted by the presence of Pond P11 was not taken into account in the modeling done for the project. Without consideration of all the factors material to the site that should enter an appropriate calculation, there is not reasonable assurance that Wetland A3 and the Cypress-forested Wetland will not suffer adverse impacts from the SWM System. Monitoring Water Quantity Section 3.2.2.4(c) of the Basis of Review states: Whenever portions of a system could have the effect of altering water levels in wetlands or other surface waters, applicants shall be required to monitor the wetlands or other surface waters to demonstrate that such alteration has not resulted in adverse impacts, or to calibrate the system to prevent adverse impacts. Monitoring parameters, methods, schedules, and reporting requirements shall be specified in permit conditions. District Ex. 4, Chapter Three, P. 6. The District determined that the routing analysis and volume calculations with regard to the hydrology on-site and the hydrology of the wetlands provided by Westfield show that there will not be significant or frequent negative changes in wetland hydrology on site. The District concluded, therefore, there is no necessity to require monitoring of wetland water levels in the Permit. The District's determination, based as it is on the ICPR modeling provided by Westfield, does not withstand the criticism by Mr. Vecchioli. If the District, in the face of the evidence of record and Mr. Vecchioli's criticism, nonetheless decides that reasonable assurances have been made by Westfield, the District should require monitoring pursuant to the subsection 3.2.2.4(c) of the Basin of Review; without doubt, the excavation of Pond P11 adjacent to Wetland A3 has at least the potential to affect water levels in the wetland system. Water Quality The depth of P11 poses some dangers to water quality. Generally, the deeper a Florida lake, the more anoxic and "the more likely you have . . . nutrients such as phosphorus, binding up in the [waterbody] and then being released later" (vol. III, p. 64) to affect the waterbodies negatively. Wetlands surrounding P11, acting like "sponges" would provide treatment that removes nutrients and locks up chemicals to reduce their toxicity would improve water quality. But the District's rules do not require biological treatment for nutrients as part of the design of a surface water system. Given its nature as an attenuation pond, P11 will act like a secondary sediment sump. This aspect of P11 contributes no treatment credit to the application, as mentioned earlier, but any water entering Wetland A3 from P11 will have been treated by an SWM System so as to meet the District's requirements. Other measures will improve water quality on- site. One of such measures, for example, is that cattle on-site will be removed. Other measures related to water quality were examined by District staff. As he testified on behalf of the District, Mr. Sauskojus "checked to see whether or not . . . erosion control was located between any construction in the wetlands and/or buffers provided." (Tr. 288). He also checked to see that structures through which stormwater flowed into wetlands were equipped with skimmers. The inquiries led him to conclude as an expert in environmental resource permitting that water quality would not be adversely affected by the SWM System. Monitoring of water quality by the District may be done after the Permit has been finally issued and the SWM System is constructed. The District so provides in the Basis of Review. Section 5.13 of the District's Basis of Review states: Staff reports and permits for projects not requiring monitoring at the time of permit issuance will include a statement that water quality monitoring will be required in the future if necessary to ensure that state water quality standards are being met. This should not be construed as an indication that the District is contemplating the implementation of a program of intensive water quality monitoring by all permittees. District Ex. 4, Chapter Five, P. 6. Assurances Other than ICPR P11's Shelf Westfield proposes creation of a shelf along the western boundary of P11. It is approximately 150 feet wide with a slope of "a hundred to one . . . a flat area . . . right around the seasonal high elevation of [the] pond." (Tr. 158). Just as it does not claim treatment credit for P11, Westfield does not claim treatment credit for the shelf. There will not be any planting on the shelf; nor is it designed to serve as a littoral zone. A "shelf is . . . in some cases the final location for . . . the filtration [and] the protection for the wetland[;] . . . it acts as a wetland buffer for the mature forested wetland." (Vol. III, p. 59). But the shelf to be provided by Westfield is "just . . . a secondary shelf to help the interaction between the wetland and the pond." (Tr. 159). Without vegetation, the shelf provided will be of insignificant benefit. Dewatering During Construction To prevent dewatering of Wetland A3 during construction, a dewatering plan must be provided the District before excavation of P11 begins. The Permit contains a general condition that if the contractor "decides to use dewatering" (tr. 223) of a wetland, the District must be notified so that an assessment of adverse effects on the wetland can be made.6 Wetland Impacts: Avoidance, Minimization and Mitigation Direct impacts to wetlands include excavation or filling: events that entail physical construction in the wetland. The Project proposes direct wetland impacts to 1.61 acres of wetlands and 2.81 acres of surface waters or wet ditches. With regard to impacts, an applicant must first attempt to avoid them. If that fails, the applicant must minimize the impact. Finally, the applicant must propose mitigation for impacts. Direct Impacts to Wetlands In addition to the secondary impacts caused by the Project's upland activities to the many wetlands on-site that are buffered or that were not buffered and that have to be offset by mitigation, Wetland B12, a wetland little more than one-half acre in size, will receive both direct and secondary impacts. The direct impact is caused by the proposed road. The direct impact is unavoidable because of road alignment required by the Department of Transportation, "a human health and safety issue [that relates] to State Road 54." (Tr. 64). The direct impact to Wetland B12 takes up .15 acres, leaving .43 acres of the wetland without direct impact. (At the same time, Wetland B9 is avoided by the curve in the proposed road and the road is aligned to avoid direct impact to Wetlands B6 and D5.) Wetland B12 is exempt from fish and wildlife review because it "is not connected by a ditch or overland flow to a larger than half-acre wetland at seasonal high " (Tr. 283). The value of Wetland B12, as an isolated wetland, is not as high as the value of Wetland A3. It has also suffered de-watering and encroachment by exotic species. Wetland C12, just down the proposed road from Wetland B12, will incur direct impact to 0.05 acres. The remainder of the wetland on site, 1.80 acres will be preserved under a conservation easement. Wetland B4 is a small, herbaceous wetland. In the middle of what is now cow pasture slated for excavation if the Project is approved, Wetland B4 will suffer permanent destruction by the creation of Pond P11. The direct impact will cover 0.75 of an acre, the size of the wetland as it now exits. Wetland C4, 0.60 acres in size, will also be permanently destroyed by the establishment of several lots in the Northern Pod of development and excavation of P4, a wet detention pond. The justification offered by Westfield for the permanent destruction of these two relatively small isolated wetlands is economic. Saving them would cost $215,000. Mitigation of the Direct Impacts The project preserves wetlands on site with conservation easements. If the wetland is a good candidate for wetland stormwater treatment, the project attempts to augment its hydrology. The direct impacts of Westfield's planned activities are proposed to be mitigated by the construction of 2.89 acres of non-forested wetlands and by the preservation of 65.32 acres of wetlands on site. Section 3.3.2 in the Basis of Review provides: Subsections 3.3.2[.1] through 3.3.2.2 [of the Basis of Review] establish ratios for the acreage of mitigation required compared to the acreage which is adversely impacted by regulated activity. District Ex. 4, CHAPTER THREE, P. 21. When preservation of wetland and other surface waters is the vehicle of mitigation, it also provides: The ratio guideline for wetland and other surface water preservation will be 10:1 to 60:1 (acreage wetlands and other surface waters preserved to acreage impacted). District Ex. 4, CHAPTER THREE, P. 24. The ratio of wetlands and other surface waters proposed for preservation (65.32 acres) to wetlands proposed to be permanently destroyed (1.61 acres) by Westfield is more than 40 to 1, well within the guideline. The wetland area to be created is designated as Wetland B2. Adjacent to two wetland systems, Wetland A3 and Wetland C2, and lying between them, Wetland B2 will also serve as a wetland habitat wildlife corridor. The 2.89 acres of created non-forested wetlands that will constitute Wetland B2 offset 1.36 of non-forested impact, a ratio of 2.13 to 1. The ratio is within the guidelines for created wetlands in Section 3.3.2.1.1. of the Basis of Review. In the District's view, the applicant's wetland mitigation proposal provides the District with reasonable assurances that impacts to wetland functions will be offset. Put slightly differently by Mr.Sauskojus, in the view of District staff, "weighing the proposed direct impacts, the secondary impacts and the mitigation provided, . . . there will not be adverse impacts on site or offsite . . . ." (Tr. 293). Since downward and lateral seepage from Pond P11 was not taken into account, however, the mitigation plan offered by Westfield is not designed to offset any impacts from the seepage to Wetland A3 and the Cypress-forested Wetland. These impacts are secondary impacts. Secondary Impacts A secondary impact is an impact that follows a direct impact to a water resource. An example of a secondary impact is boat traffic increase because of the installation of a boat ramp or a marina that poses an increased threat of collision with manatees. The construction of the boat ramp or the marina would entail direct impacts to the water resource. The increased boat traffic would constitute impacts secondary to the construction of the ramp or marina. A way to minimize secondary impacts is through buffers. Just as the Cypress-forested Wetland should be buffered from development, so should the isolated wetlands on-site. Isolated wetlands are important for several reasons. They accept the brunt of the discharges from the developed uplands and so are responsible for filtering nutrients, pesticides and chemicals from stormwater and other run off. They also are spots where wildlife congregate. Birds, in particular, will be under siege from the cats that inevitably accompany development. Buffers, particularly vegetated buffers, assist in protection of wetlands whether contiguous or isolated. Section 3.3.7 of the Basis of Review provides: Secondary impacts to habitat functions of wetlands associated with upland activities will not be considered adverse if buffers, with a minimum width of 15' and an average width of 25' are provided abutting those wetlands that will remain under the permitted design, unless additional measures are needed for protection of wetlands used by listed species for nesting, denning, or critically important feeding habitat. District Ex. 4, CHAPTER THREE, Pg. 16. The upland activities of the Project have an average 25-foot buffer. For the bulk of the Project, the buffer is at least 15 feet, a minimum buffer that is normally required. Close to the headwaters of Wetland A3, however, the Southern Pod of development does not have a buffer that is equal to or more than 15 feet. In this area and other areas where there are less than 15 feet of buffer (such as around isolated Wetlands B8 and D3), the Project calls for a double silt fence, that is, a two- rowed fence to hold back silt. The silt fence will protect the wetland from damage during grading of the lots and construction of the residences. But it will not protect the wetland from secondary impacts caused by upland activities after the Project is developed. The buffers are made up of bahaia grass primarily. The import of the buffer's composition was explained at hearing by David Sauskojus, a District employee: If a buffer is made up of pasture grass, it is definitely much less effective relative to protecting habitat functions than . . . an undisturbed upland. . . . [I]n this case, . . . in the past before they made it pasture, [the undisturbed upland would have] consisted of palmettos, bryonia, bushes, [and] shrubs, that would have provided some kind of habitat value to the wetland itself. (Tr. 282). Despite the low quality of the composition of the buffers, the additional width of buffers in other areas that allow the average of the buffers to exceed 25 feet was reasonable assurance in the view of District personnel that the encroachment of development closer than 15 feet in certain areas would not have secondary habitat impacts to Wetland A3. Because of this "offset," the District did not request the applicant to mitigate for the encroachments into the minimum 15 feet of buffer normally required. Cumulative Impacts Section 3.2.8.1 of the Basis of Review provides: Cumulative impacts are considered unacceptable when the proposed system, considered in conjunction with the past, present, and future activities as described in 3.2.8 would then result in a violation of state water quality standards as set forth in subsection 3.1.1(c) or significant adverse impacts to functions of wetlands or other surface waters identified in subsection 3.2.2 within the same drainage basin when considering the basin as a whole. District Ex. 4, CHAPTER THREE, P. 19. The Project will not cause unacceptable cumulative impacts on the wetlands and other surface waters on site. Fish, Wildlife and Listed Species Under the Basin of Review, when a party applies for an ERP, "[g]enerally, wildlife surveys will not be required." District Ex. 4, Basin of Review, Section 3.2.2, CHAPTER THREE, page 4. The Basin of Review details when a wildlife survey is required: The need for a wildlife survey will depend upon the likelihood that the site is used by listed species, considering site characteristics and the range and habitat needs of such species, and whether the proposed system will impact that use such that criteria in subsection 3.2.2 through 3.2.2.3 and subsection 3.2.7 will not be met. Survey methodologies employed to inventory the site must provide reasonable assurance regarding the presence or absence of the subject listed species. Id. It is apparent from the record that District staff initially believed that a wildlife survey was needed. The file of record contains a document prepared by District staff entitled "Project Information Review List," (the "First Request for Additional Information" or "1st RAI"). Dated March 7, 2003, it refers to the Application's receipt one month earlier. Under the heading "SITE INFORMATION," the following appears: Has any current wildlife survey been performed on site? In particular, what recent observations have been made of wildlife usage within Wetlands B4, C4 and B12? The submitted wildlife survey not only is almost three years old, but it represents a preliminary effort. (emphasis supplied), Westfield Ex. 19, File of Record,(1st Volume), p. 104. The staff request for additional information continues with recommendations not only to cure the outdated nature of the survey but also for the methodology that should be used: Id. Staff would recommend, for the above three wetlands, that a survey be performed which is consistent with Florida Fish and Wildlife Conservation Commission's methodology, documented within; Standardized State Listed Animal Species Survey Procedures for FDOT Projects by Jim Beaver, revised in 1996, and Wildlife Methodology Guidelines by Mike Alan, 1988. Reference Rules 40D-4.101(1)(c) and (e) and 40D-4.301, F.A.C. and Section 3.2.2, Basis of Review (B.O.R.). The file of record reflects a response to the 1st RAI. With regard to the question as to whether a current wildlife survey has been performed, the criticism of the submitted survey and the recommended methodology to be used in a subsequent survey, Westfield's ERP consultant, King Engineering Associates, Inc., ("King") responds: Site conditions have not changed since King conducted the original preliminary listed species survey. During more recent site visits, King staff have not observed any additional listed species, or evidence of their breeding/nesting activity on the subject property. Onsite wetlands B4 and C4 are essentially shallow, wet depressional areas in the pasture. While these herbaceous wetlands could potentially provide occasional foraging habitat for wading birds, they do not represent suitable habitat for breeding/nesting of any listed species. Wetland B12, a forested wetland, likewise does not represent suitable habitat for breeding/nesting of listed species, and no listed species have been documented in this wetland. As a follow-up effort to King's preliminary listed species survey, and following recommendations made in that report, King has performed additional wildlife surveys. Specifically, a Southeastern Kestrel Survey and Gopher Tortoise Burrow Survey were conducted by King. The results of these follow-up surveys, which were included with Attachment 7 of the original submittal, revealed that neither of these two listed species is currently present on, or breeding/denning on, the subject property. Westfield Ex. 19, File of Record, (1st Volume), p. 123. On May 7, 2003, the District responded by letter to the additional information provided by King with a second Request for Additional Information (the "2nd RAI"). The letter states, "[y]our permit application still lacks some of the components necessary for us to complete our review; the enclosed checklist describes the missing information." District Ex. 19, File of Record, (1st Volume), p. 184). The checklist attached, under the heading "SITE INFORMATION" states: The response to Request for Additional Information (RAI) Comment No. 3, regarding wildlife surveys, does not give the District reasonable assurance that threatened or endangered species do not use the wetlands proposed to be impacted. Many changes have taken place in the vicinity of the project since King performed the preliminary survey three years ago. The construction of the Suncoast Parkway and several nearby residential developments have re-shaped habitat availability within this area. The District strongly recommends performing a wildlife survey to evaluate the usage by threatened or endangered species of Wetlands B4, C4 and B12. The survey should be performed using the previously noted Florida Fish and Wildlife Conservation Commission (FFWCC) methodology. Additionally, when/if the survey is performed, please provide details regarding the actual survey, including but not limited to, dates, times of day, location and methods used. Westfield Ex. 19, File of Record (1st Volume), p. 185. On June 20, 2003, King responded in writing to the 2nd RAI. With regard to the strong recommendation of a wildlife survey that uses the FFWCC methodology, King wrote: The applicant is confident based on the results of the existing Preliminary Listed Species survey and the extended amount of property contact time by field scientists and District staff in the intervening months when hydro-period, wetlands delineation, and permit application work were on-going, that no wetland dependent species are present. Westfield Ex. 19, File of Record, (1st Volume), p. 198. In addition to the time spent on the preliminary survey, the response lists 64 hours of time when the site was visited for purposes of "[w]etland delineation, wetland delineation & [h]ydro-periods," "h]ydro-periods," "[h]ydro-period [r]eview with SWFWMD," "[f]ollow-up Gopher Tortoise/Kestrel [s]urvey" and "[f]ield [v]isit with ACOE staff." Id. On July 18, 2003, a third RAI ("3rd RAI") was issued by staff. Satisfied with the June 20, 2003, response with regard to the earlier inquiries about a wildlife survey, the 3rd RAI makes no reference to the earlier requests with regard to site information or the need for wildlife survey. Dr. Baca, Dr. Blanco's wetlands ecologist, criticized the wetland information provided by Westfield along the same lines as did District staff in the documents in the file of record. For example, Dr. Baca testified with regard to endangered species that a survey should be conducted over several seasons. A great deal of time must be spent studying the particular habitat and looking for particular organisms. "It cannot be an aside to other work . . . with wetlands or soil studies . . . [i]t has to be a focus of [a wildlife survey]." (Vol. III, tr. 33). A survey for endangered or threatened species requires time and focus precisely because of the nature of listed species; in Dr. Baca's words, "they're not around very much and sometimes they're not around very long." (Vol. III, tr. 32). Time of day that a survey is conducted, moreover, has an impact on the likelihood that wildlife will be found on site. As Dr. Baca testified, Most of the time, you'll find more wildlife on-site around the hours of dusk and dawn . . . Other times, especially during cold weather, wildlife will come out during the hottest part of the day, which is around noon . . . [a]ll of these add to the amount of time that would be required to do a proper study. (Vol. III, Tr. 33). There is no evidence of record as to time of day of the visits used by Westfield for credit toward wildlife observation. Finally, it is apparent that the on-site visits following the preliminary species survey three years prior to the submission of the application did not employ the methodology recommended by the District: the FWWCC methodology. Perhaps an equivalent methodology could be employed, but there is no evidence of an attempt to conduct a survey with an acceptable methodology, either that of FWWCC or an equivalent. The District's acceptance of the Kestrel Survey may have been appropriate.7 But the hours spent visiting the site for wetland delineation and purposes other than to survey wildlife were not shown to have employed the FWWCC methodology or its equivalent and do not supplant the need for a wildlife survey that employs an appropriate methodology. The Mitigation Plan When the impacts of a project that requires an ERP permit are such that an applicant is unable to meet the criteria for approval (the "public interest test"), the applicant may propose or accept measures that mitigate the adverse impacts of the regulated activity so that the Project in its entirety can be demonstrated to be "not contrary to the public interest." In other words, "[t]he mitigation must offset the adverse effects caused by the regulated activity." § 373.414(1)(b), Fla. Stat. It is "the responsibility of the applicant to choose the form of mitigation." Id. As explained by the testimony, all of the mitigation proposed by Westfield is on-site.8 The Respondents' Joint Proposed Recommended Order addresses mitigation for the adverse impacts caused by the Project. The proposed findings that relate to mitigation are summed up in paragraph 16 of the proposed order: 16. The mitigation for the project is appropriate and adequately compens[]ates for the unavoidable direct and secondary wetland impacts from the Project. Respondents' Joint Proposed Recommended Order, p. 6. In support of this finding, the proposed order cites to the File of Record, Westfield Ex. 19, testimony from Mr. Courtney at Tr. 66-76 and 120-121 and testimony from Mr. Sauskojus at Tr. 284-286. Mr. Sauskojus' testimony explains how the mitigation plan adequately mitigates for the direct impacts to wetlands on site. But that explanation does not demonstrate mitigation for all of the potential impacts. No effort was offered for how the plan was designed to mitigate for the impact of draw-down from Wetland A3 caused by low elevation of Pond P11 due to seepage, for example, because seepage was not accounted for in the ICPR modeling. Mr. Courtney's testimony is no different with regard to the same critical omission. Westfield, quite simply, did not take into account, as Mr. Vecchioli testified, the effect of seepage in the information it provided the District. Nor was the mitigation plan designed to mitigate for secondary impacts that might have been indicated by a wildlife survey since an appropriate wildlife survey was not conducted. At bottom, Westfield did not provide reasonable assurances as required by the statutes and rules; it omitted an adequate wildlife survey from the submission of information to the District and it failed to account for seepage from Pond P11 and its effect on Wetland A3 and the Cypress-forested Wetland. Its mitigation plan does not make up for Westfield's failure to demonstrate that the Project is otherwise "not contrary to the public interest."
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Individual Environmental Resource Permit sought by Entryway and Westfield be DENIED. DONE AND ENTERED this 17th day of December, 2004, in Tallahassee, Leon County, Florida. S DAVID M. MALONEY Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 17th day of December, 2004.
The Issue This case involves a third-party challenge to South Florida Water Management District's (District's) proposed issuance of Amended Environmental Resource Permit number 43- 01438-P (ERP) for conceptual approval for a surface water management (SWM) system to serve 80.71 acres of residential development known as The Gables at Stuart and 1.42 acres of the entrance road easement. The issue to be decided by the ALJ is whether The Gables at Stuart (The Gables) provided reasonable assurances that the proposed development will not be harmful to the water resources of the District, and will comply with the water quantity, environmental and water quality criteria of the District's ERP regulations set forth in Part IV of Chapter 373, Florida Statutes, in Florida Administrative Code Chapter 40E-4, and in the Basis of Review for ERP Applications (BOR) (collectively referred to as the ERP criteria).1
Findings Of Fact The Parties and Proposed Project The Gables project site is located within the jurisdictional boundaries of the District in Martin County, Section 20, Township 37 South, Range 41 E, bordered to the north by Jensen Beach Boulevard and a 18.64-acre tract of commercial property that was previously included in the proposed project. To the west and partially to the south is the Pineapple Plantation residential development, and to the east is the Pinecrest Lakes residential development. The Petitioner resides in the Pineapple Plantation development which borders the Gables site. The Gables project site contains 29.54 acres of wetlands; 26.86 of these will be preserved onsite. Additionally, the project will include a conservation easement encompassing 32.7 acres which covers both wetlands and uplands. Development on the site will cover only 28.04 acres; the remaining acreage which is not under a conservation easement will nonetheless be preserved. Wetlands 1, 2, 3, and 4, which are the larger, higher quality wetlands on the site, will be entirely preserved, except for a 0.11 acre area in the southeast corner of wetland 1, where a berm will be constructed. All direct wetland impacts will result from construction of the multi-family housing and its access road on the northern portion of the site. These wetlands are in a more degraded condition than are the wetlands to the south, which are being preserved. The site includes the alignment of the proposed “Green River Parkway” for which Martin County has submitted a permit application. Although this area and the area to the east of it will be preserved by the Gables, no mitigation credit is given by the District. In fact, portions of wetlands 5 and 6 that are east of the proposed alignment have been considered by the District as secondarily impacted due to the fragmentation and size reduction expected to result from construction of the Parkway even though they are not impacted by the Gables project itself. The site is characterized by pine flatwoods and wet prairies typical of those found along the upper edges of the Savannas in Martin and St. Lucie Counties. The Gables project site is undeveloped but has been hydrologically altered in some areas by offsite conditions. In particular, a large ditch on the west side of the Pinecrest Lakes property adjacent to the eastern boundary of the subject property presently exerts adverse hydrologic affects, as does the entire Pinecrest Lakes development. There is an existing culvert outfall across Jensen Beach Boulevard in the northwest corner of the 18.64-acre commercial property to the north. Runoff from a portion of Jensen Beach Boulevard and undeveloped portions of the West Jensen project are conveyed into the commercial property by this culvert. This runoff then flows easterly and south within the commercial property and, ultimately, under an existing unpaved road used to access two Martin County Utility potable wells located in the eastern project area. The previously referenced north-to-south ditch located along the western edge of the adjacent Pinecrest Lakes project directs this flow southerly into the Pinecrest Lakes Phase I SWM system. A ridge traversing the northern portion of the Gables project site from west to east prevents appreciable volumes of this off-site discharge from reaching wetlands south of this ridge. In general, wetlands found over the southwestern one- half of the Gables project site are in very good condition, displaying healthy and appropriate vegetation and water levels. The northeast one-half was observed to have significantly less standing water when inspected, and vegetation appeared to be transitioning to less water-tolerant species such as slash pines. The southern portion of the Gables project site consists largely of wetlands. Wetlands designated as Wetlands 4 and 7B extend off-site westerly into the neighboring Pineapple Plantation development. The northernmost 18.64 acre commercial portion of the July 2003 Gables project site has been removed. The commercial portion will require a separate permit prior to any development on that parcel. The Gables has proposed an exfiltration trench to provide runoff from its multi-family section, which is on the northern portion of the site, with dry pre-treatment equal to one-half inch over the area prior to discharge into the master SWM system. An exfiltration trench consists of buried perforated piping surrounded by gravel which allows runoff to be filtered and treated before exiting the system. The southernmost area of the Gables development is to consist of single-family residential development located in an upland peninsula in the central western portion of the overall Gables project site. This area will be surrounded by a retaining wall. Runoff from the lots and the access road within the single-family area will be directed to the wet detention lakes of the master SWM system. The master SWM system water quality and storm attenuation facilities include 2.415 acres of wet detention pond to be located in the central eastern project site area, as well as dry detention areas, swales and the exfiltration trench located within the project. Discharge from the master SWM system is into the adjacent Pinecrest Lakes development within a previously established drainage easement. The revised conceptual design for the Gables project site continues to re-route the existing historical off-site discharge from West Jensen and Jensen Beach Boulevard southward to the on-site wetlands through a dedicated culvert conveyance that will commence at the northern boundary of the revised Gables project site area. Conveyance through the formerly included commercial tract will be through existing wetlands. The master SWM system conceptual design will continue to utilize a cascading wetland system, cascading from west to east in accordance with the natural hydrology of the site, with final connection into the master SWM wet detention pond. As the Gables application is for a conceptual permit only, final construction details are not required to be presented at this time, and modifications are to be expected when the applicant files an application for a construction permit. Conditions For Issuance In order to obtain an ERP, an applicant must satisfy the conditions for issuance set forth in Rules 40E-4.301 and 40E-4.302. The Conditions for Issuance primarily focus on: a) water quantity, b) wetland environmental values, and c) water quality. Water Quantity Under Rule 40D-4.301(1), an applicant must provide reasonable assurance that the construction, alteration, operation, maintenance, removal, or abandonment of a surface water management system: will not cause adverse water quantity impacts to receiving waters and adjacent lands; will not cause adverse flooding to on- site or off-site property will not cause adverse impacts to existing surface water storage and conveyance capabilities. The Applicant has demonstrated through hydrological analysis, which takes into consideration the systems on the surrounding properties, the hydrologic inflow from the north, from the West Jensen project, that the proposed project will not cause flooding to on-site or off-site property. Petitioner alleged that the proposal to install a berm around wetland 7 on the Gables property would cause flooding into Pineapple Plantation. But the evidence was that Pineapple Plantation’s SWM system, as permitted, was intended to contain the runoff within the boundaries of Pineapple Plantation’s property, including the small portion of wetland 7 that straddles the property line between Pineapple Plantation and The Gables. To accomplish this, permission was obtained from Mr. Gibson to install a berm on his property. However, the berm was never installed. The Gables now proposes to install the berm that was supposed to have been there since Pineapple Plantation was permitted. The proposed berm would be established at an elevation sufficient to control runoff produced by a 25-year rainfall event and maintain the previously-established hydrologic divide. For these reasons, installation of the proposed berm, which is necessary to make The Gables' proposed SWM system function properly, will not cause adverse flooding to the Pineapple Plantation. For various other reasons, Petitioner also alleged that The Gables project will lower wetland water levels in Pineapple Plantation, as well as on the Gables property, having adverse impacts on the quality of those wetlands. Petitioner did not present any expert opinion to support his allegations. Instead, he primarily pointed out what he termed "anomalies" in the permit file during cross-examination of expert witnesses for The Gables and the District. In most instances, the expert witnesses explained that Petitioner was mistaken. In every instance where Petitioner had detected an actual "anomaly," the experts explained that they were insignificant for purposes of the permitting criteria. The Gables provided reasonable assurances that it will not cause adverse impacts to existing surface water storage and conveyance capabilities through the determination of appropriate wetland control elevations which are based on wet season water levels. Petitioner raised a question regarding aquifer recharge, which is a consideration under Section 6.10(e) of the BOR, which requires the project to be designed to "preserve site ground water recharge characteristics." The project is designed so that water tables are preserved or even raised. It is also designed to preserve the significant wetland features of the site. There are large areas of contiguous areas of wetland and upland habitat which can function as groundwater recharge. The exfiltration trenches make runoff also available to the aquifer for storage. The lakes are not lined, so the water in the lake can leak out. Based on volumetric calculations, the site will have more water post-development than predevelopment. The types of regional investigations of aquifer recharge capabilities and impacts cited by Petitioner were relevant to consideration of groundwater withdrawal issues, not surface water management design. In conclusion, The Gables provided reasonable assurances that it would comply with the District rules pertaining to water quantity and flood control pursuant to Rule 40E-4.301(1)(a),(b), and (c) and the BOR. Value Of Functions Of Wetlands Rule 40E-4.301(1)(d) requires an applicant to provide reasonable assurances to demonstrate that its proposed project will not adversely impact the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters. The wetlands generally located on the north side of the Gables project site are in a more degraded condition than the wetlands to the south. Wetlands generally located over the southerly extent of the site are adequately hydrated and possess high-quality vegetation associations consisting of St. John's wort, maidencane, yellow-eyed grass, and beak rush. This habitat lends itself to utilization by a variety of wading birds, raptors, snakes, and small mammals such as raccoons, bobcats, armadillos, opossums, and feral pigs. In contrast, Wetlands 5, 6, and 7 on the north side exhibit slight-to-significant hydrologic and vegetation changes due to the adjacent Jensen Beach Boulevard and Pinecrest Lakes development to the north and east, respectively. The Gables is proposing both wetland and upland preservation. A mosaic of uplands and wetlands together enhances the value of both and provides a good habitat for wildlife. Mixing upland preservation mixture with wetland preservation increases the value of the wetlands because uplands support wetland habitat, and the “ecotone” at the edge of the upland and wetlands provides the most valuable part of the habitat. The value of preserving this area outweighs potential preservation of the less valuable wetlands to the north, which will be impacted by the multi-family portion of the project. The Gables has provided reasonable assurances to demonstrate that the value of functions provided by wetlands and other surface waters will not be adversely affected. Water Quality Rule 40E-4.301(1)(e) requires an applicant to provide reasonable assurances that the proposed project will not adversely affect the quality of receiving waters such that state water quality standards will not be violated. Section 5.2.1 of the BOR requires that retention, detention, or both retention and detention be provided in the overall system in one of the following three ways or equivalent combinations thereof: Wet detention volume shall be provided for the first inch of runoff from the developed project, or the total runoff of 2.5 inches times the percentage of imperviousness, whichever is greater. Dry detention volume shall be provided equal to 75 percent of the above amounts computed for wet detention. Retention volume shall be provided equal to 50 percent of the above amounts computed for wet detention. Retention volume included in flood protection calculations requires a guarantee of long term operation and maintenance of system bleed-down ability. The Gables has proposed an exfiltration trench system for the multi-family parcel and a lake system to handle runoff from the overflow and from the single-family portion of the project. With these facilities in place, runoff from the proposed development will be treated before any stormwater is discharged off site. Calculations were performed to ensure that the project is engineered to meet these criteria. Petitioner suggested that the project may require more exfiltration trench than in the current plans, due to compaction of the soil from construction activities, which may affect permeability. However, Petitioner presented no evidence to support this suggestion. The expert witness for the Gables explained that compaction usually affects the top two feet of the soil profile, whereas the exfiltration trenches are designed to be 4-5 feet below the ground surface and probably will function as expected. In any event, when a construction permit is sought, final testing will be performed and additional trench will be installed if necessary. The project will accommodate double the amount of exfiltration trenching in the conceptual plan. The Gables has provided reasonable assurances to demonstrate that the project will not adversely affect the quality of receiving waters such that State water quality standards will not be violated. Reduction And Elimination Section 4.2.1 BOR requires that practicable design modifications be explored to reduce or eliminate adverse impacts to wetlands and maximize functions provided by wetlands on the project site. The applicant explored all practicable alternatives in order to reduce or eliminate wetlands impact. In 2000, the Applicant proposed approximately 7.5 acres of wetland impact. In 2001, the Applicant submitted a plan to the District that preserved part of Wetland 5 and impacted the remainder of Wetland 5 by dredging a lake. The current application proposes preserving more of Wetland 5 and three smaller lakes, rather than a single lake, which has the effect of further decreasing wetland impacts The site plan was also modified to address flowage from north of Jensen Beach Boulevard to the south, thereby reducing secondary impacts to all the wetlands that are now being preserved. In addition, a retaining wall has been added around much of the development to offset secondary impacts, and additional buffers have been put in place. Finally, as noted above, the preservation of a large tract of mixed upland and wetlands is more beneficial than preservation of a small amount of degraded wetlands. Conceivably, wetland impacts could be further reduced or eliminated by further decreasing the amount of development. But given the present layout of the proposed site plan, a further reduction would not be considered practicable. Therefore, The Gables has adequately applied the reduction and elimination criteria as required by the BOR and the District's regulations. Secondary Impacts Secondary impacts are indirect impacts that are reasonably expected to occur as a result of development. Rule 40E-4.301(1)(f) and Section 4.1.1(f) of the BOR require an applicant to provide reasonable assurances that the proposed activities will not cause adverse secondary impacts to the water resources. The District conducted a secondary impact analysis and assessed secondary impacts to wetlands 5, 6, and 7. A small portion of wetland 1, which extends off-site, was also assessed as a secondary impact because approximately half an acre of it is cut off by a proposed berm. Pursuant to Subsection 4.2.7(a) of the BOR, a 25- foot buffer is required around a wetland to prevent secondary impacts. Except for the small portion of wetland 1 discussed above, wetlands 1, 2, 3, and 4 will not be secondarily impacted because each wetland has at least a 25-foot buffer and, in some cases, a retaining wall. Mitigation An applicant is required to mitigate for secondary impacts as well as for direct wetlands impacts.3 The Gables is providing a conservation easement in favor of the District to include 18.26 acres of high-quality uplands and 20.8 acres of high-quality wetlands, though mitigation credit is being allowed by the District for only 5.79 acres of the upland portion. The value and importance of a conservation easement is that it provides reasonable assurances that a resource will not be developed in the future. Inclusion of uplands in a conservation easement is particularly valuable because development of uplands ordinarily would be more likely, and because combining wetlands and uplands in a conservation easement has the effect of enhancing the value of the wetlands by encouraging their use by wildlife. Under Section 373.414, Florida Statutes, the Uniform Mitigation Assessment Method (UMAM), which is implemented through Rule Chapter 62-345, wetland impacts from the proposed project will result in 2.63 units of functional loss, while proposed mitigation will provide 2.87 units of functional gain. This UMAM analysis demonstrates that the proposed mitigation offsets wetland impacts. Petitioner questioned whether The Gables and the District properly applied Rule 62-345.600(3)(c) in determining the amount of required mitigation. Specifically, Petitioner contended that, since The Gables is not using a mitigation bank or a regional offsite mitigation area as mitigation, the acreage of mitigation required to offset wetland impacts was to be calculated by dividing functional loss (FL) by relative functional gain (RFG). However, Petitioner did not explain what the result would be if this calculation were made. Meanwhile, the expert witnesses for both the District and The Gables interpreted the language of the Rule to provide that one divides FL by RFG to determine acres of mitigation required only when one discrete area is being impacted and another discrete area is serving as mitigation, which is not the case here. According to the experts, the second sentence of subparagraph (3)(c) explains that, when there is more than one impact or mitigation assessment area, total functional loss and total RFG for each assessment area is determined by summation of the FL and RFG for each assessment area. While the language of the Rule is confusing, the expert testimony is credited and accepted as providing a logical and correct interpretation. The BOR specifically provides in Section 4.3.1.2 that mitigation is best accomplished on-site or in close proximity to the area being impacted. In this case, all of the mitigation proposed is onsite.4 Section 4.2.2 of the BOR provides that as part of the District's assessment of impacts of regulated activities upon fish and wildlife and their habitats, the District will provide notice of ERP applications to the Florida Game and Freshwater Fish Commission (now the Fish and Wildlife Commission, or FWC) for its review and comment. The FWC did not comment on the Gables at Stuart application. The U.S. Fish and Wildlife Service wrote a letter to the U.S. Army Corps of Engineers in 2003, stating that it did not object to the applicant’s wetland impacts and proposed mitigation plan for the proposed project. The Gables provided reasonable assurances that mitigation will offset all impacts to wetlands. Petitioner's Extrapolation from Well Permitting Concerns Petitioner's testimony at final hearing revealed his challenge was motivated by his belief that, because the District has denied applications for permits to withdraw substantial amounts of groundwater in the region, in part due to potential impacts on surficial aquifer and wetlands, it does not make sense to allow any impacts to wetlands in SWM permitting. However, SWM permitting is governed by the criteria discussed above, not the criteria of consumptive use permitting. In addition, the potential impacts of massive consumptive use of groundwater cannot be compared to wetland impacts of the Gables proposal. Finally, as indicated, The Gables has established water table elevations for resulting wetland systems based on the existing condition of those wetlands. In some places, The Gables has proposed to raise water levels to benefit the wetlands and raise the water table above what it has been historically, primarily along the eastern boundary of the property in the Pinecrest Lakes subdivision. This has the effect of maintaining if not raising groundwater levels.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the South Florida Water Management District enter a final order issuing to The Gables ERP number 43-01438-P, to expire in two years, subject to the conditions set forth in the Amended Staff Report. DONE AND ENTERED this 16th day of March, 2006, in Tallahassee, Leon County, Florida. S J. LAWRENCE JOHNSTON Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 16th day of March, 2006.
The Issue The issue is whether Respondent Crestwood Lakes Associates provided reasonable assurance that a modification to a conceptual surface water management permit complies with the permit criteria contained in statutes and rules.
Findings Of Fact Background This case involves a 900-acre parcel in the Loxahatchee Slough, west of the Florida Turnpike in Palm Beach County (County). Although the property occupies part of a slough, all of the wetlands in this case are isolated wetlands. Respondent Crestwood Lakes Associates (Applicant) owns the south 503 acres, Petitioner owns the north 287 acres, and the Village of Royal Palm Beach (Village) owns the remaining 115 acres, which abut the southwest boundary of the north parcel. The acreages do not total 900 acres because the numbers are approximate. The 900-acre parcel is generally bounded on the south by Okeechobee Boulevard and the north and east by the M-1 canal. The west boundary of the south part of the parcel adjoins a residential development known as Loxahatchee Groves, and the 115-acre parcel adjoins a County-owned preserve of at least 600 acres. Applicant’s land is undeveloped except for some landclearing. Petitioner’s land is partly developed, mostly in the south next to the boundary with Applicant’s land. The Village's 115 acres are a preserve, divided equally between wetlands and uplands. On February 11, 1988, Respondent South Florida Water Management District (District) issued surface water management (SWM) permit No. 50-00618-S-02 to Royal Palm Homes, Inc. for conceptual approval of a SWM system serving a residential development on the 900-acre parcel (1988 Permit). References to the Original Developer shall include Royal Palm Homes, Inc., its agents, lenders, and assigns, except for Petitioner and Applicant. The permitted development, which was known as the Royal Palm Homes PUD, comprises single-family and multifamily residences, wetland preserve areas, two 18-hole golf courses, and a park area. On August 3, 1994, Applicant filed SWM application number 940803-6 to modify the 1988 Permit to show the change in ownership and obtain conceptual approval of a modification to the permitted SWM system. The application was not complete when the new Environmental Resource Permit (ERP) rules replaced the old Management and Storage of Surface Water (MSSW) permit rules. On May 24, 1996, the District transmitted the staff report, which proposed the issuance of a permit modification. On June 13, 1996, the District approved the issuance of the proposed permit modification. On the same date, Petitioner filed its petition challenging the proposed agency action. Permits The first relevant SWM permit for the 900-acre parcel involved a larger parcel that includes the 900-acre parcel. On September 14, 1978, the District issued a two-page permit authorizing the “construction of a water management system serving 2073 acres of residential lands by waterways discharging into canal C-51.” This 1978 permit, which is identified as number 50-00618-S, contains a special condition calling for a minimum finished floor elevation of 18.0 feet National Geodetic Vertical Datum (NGVD). The next permit is the 1988 Permit, which is a substantial modification to the 1978 permit. The 1988 Permit covers only the previously described 900 acres and, as modified, currently remains in effect. The 1988 Permit requires the preservation of two large wetlands in the north parcel, just north of the 115-acre preserve; one wetland is about 30 acres and the other is about ten acres. The 1988 Permit requires the preservation of no other wetlands in the north parcel, but, in addition to the wetlands in the 115-acre preserve, the 1988 Permit requires the preservation of several much smaller wetlands in the south parcel. The staff report for the 1988 Permit divides into three basins the drainage area for the 900-acre parcel: a north basin of 98.9 acres, a central basin of 525.7 acres, and a south basin of 270.8 acres. The staff report states that basin runoff will pass through a system of inlets and culverts into a series of interconnected lakes, from which, through control structures, the runoff will pass into the M-1 canal and eventually into the C-51 canal. The staff report notes that the control elevations will be 17.25 feet NGVD for the north basin, 17.55 feet NGVD for the central basin, and 17.75 feet NGVD for the south basin. Under the discussion of environmental impacts, the staff report observes that the 1978 permit proposed for protection only 30 acres of wetlands among the 281 acres of isolated wetlands on the site. The staff report notes that “extensive” melaleuca invasion has taken place since the 1978 permit and only 160 acres of wetlands remain in “relatively good” condition, with much of this subject to melaleuca encroachment. Due to the “extensive seed source” and “seasonal drying of the wetlands,” the staff report predicts eventual melaleuca dominance of the “entire site.” The staff report asserts that the proposed development plan includes the protection of about 100 acres of the “best quality wetlands,” plus eight acres of wetlands created in conjunction with the golf courses and 15 acres of wetlands created as littoral zones in conjunction with the lakes to be constructed. The staff report calls a program “to eradicate all melaleuca from the site” “[t]he major environmental feature” of the proposed development plan. But this major environmental feature of the 1988 Permit is presently in jeopardy. One major component of the present case is that, following the conveyances of the three parcels by the Original Developer, the District has evidently concluded that no one is responsible to perform certain obligations under the 1988 Permit and no remedies are available for the nonperformance of these obligations. It appears that these conclusions are largely driven by the vagueness of the plan to eradicate the melaleuca. This plan is called the "Melaleuca Eradication Plan." The Melaleuca Eradication Plan is incorporated into the 1988 Permit. The Melaleuca Eradication Plan, which is dated December 11, 1987, recounts that the Original Developer and regulatory bodies agreed that the melaleuca should be “eradicated and a program for this should be developed and included as a part of the permit application.” The plan states that the eradication plan will cover the entire 900- acre site with the Original Developer performing the “initial . . . program” on the entire site, including the 115-acre preserve to be deeded to the Village. The Melaleuca Eradication Plan calls for the Original Developer to create a bonded authority to conduct the “ten-year melaleuca eradication program.” The program is phased to coincide with the projected 10-year buildout of the 3000-unit parcel. The Melaleuca Eradication Plan describes in detail the three phases of the program and exactly how the Original Developer will proceed to remove the melaleuca and restore wetlands by planting native wetland species in disturbed areas. The plan promises a yearly inspection followed by hand-removal of any seedlings discovered on the site. This last phase will terminate ten years after commencement of the first phase. A “Wetlands Monitoring/Maintenance Program” is also incorporated into the 1988 Permit. The Wetlands Monitoring/Maintenance Program, which is dated December 8, 1987, states that Dr. Dwight Goforth performed a wetlands survey of the 900-acre site in 1985 and divided wetlands into three categories based on their quality. The Wetlands Monitoring/Maintenance promises the preservation of 112.71 acres of wetlands comprising 98.81 acres of “large wetlands totally preserved” and nine wetlands totaling 13.9 acres that will be “partially preserved.” Also, the program will create golf course wetlands of 6.93 acres and littoral-zone wetlands around the lakes of 15 acres. Thus, the program summarizes, the “total wetland acreage preserved, enhanced and created will [be] 134.64 acres.” The Wetlands Monitoring/Maintenance Program describes a three-year monitoring program using transects to assist in the vegetative mapping of the site. The program also promises semiannual observations of birds, small rodents, and larger mammals using the wetlands and adjacent preserved uplands, as well as semiannual sampling for fish, macroinvertebrates, and amphibians. The Wetlands Monitoring/Maintenance Program outlines a plan to remove melaleuca and control algae buildup in the lakes. The program promises to contain algae through the use of “biological controls” and, when needed, hand-raking. The program also assures that the Original Developer will use a “conservative fertilization program” for the golf course and landscaped areas to reduce eutrophication in the created lakes. On February 18, 1988, the District issued its conceptual approval of the 1988 Permit. Among the special conditions of the 1988 Permit are Special Condition 15, which requires wetland monitoring and maintenance in accordance with the Wetlands Monitoring/Maintenance Program, and Special Condition 16, which requires melaleuca removal in accordance with the Melaleuca Eradication Plan. Also, Special Condition 17 requires low berms around protected or created wetlands, including littoral zones, to protect against sheetflow runoff from the golf course or other areas of intense development. The references in the preceding paragraphs to the responsibilities of the "Original Developer" imply greater clarity than is present in the Melaleuca Eradication Plan or Wetlands Monitoring/Maintenance Program. The passive voice predominates in both these documents, so it is sometimes difficult to determine on whom a particular responsibility falls. The Melaleuca Eradication Plan states clearly that "[the Original Developer] will conduct the initial melaleuca eradication on the entire site including the dedicated park area [i.e., the 115 acres]." The next sentence of the plan contemplates the conveyance of the 115 acres to the County. But, after these clear provisions, the Melaleuca Eradication Plan lapses into the passive voice almost invariably. The next two sentences read, "A bonded authority will be created to conduct the ten-year melaleuca eradication program" and "The eradication program will be carried out through a bonded agreement with the [Original] Developer to remove the melaleuca . . .." Alluding to the several phases of melaleuca eradication, the plan states only "[t]he eradication program will be completed in stages " Only two other sentences establishing responsibility for melaleuca eradication identify the responsible party. The end of the plan states that the "bonded authority responsible for initial eradication clearance will likewise provide a yearly inspection." One of the final sentences of the plan adds: "the bonding authority's crew will hand remove entire seedlings found on site." The Wetlands Monitoring/Maintenance Program is similar except that it does not once name the entity responsible for the monitoring and maintenance duties or hiring the firm or individual to conduct the actual work. The two special conditions incorporating these two documents likewise are in the passive voice, implying only that the responsibility belongs to the Original Developer. Given the vagueness of the melaleuca-eradication and wetlands-maintenance documents, it is not surprising that they fail entirely to address the issue whether these responsibilities run with the land, remain the responsibility of the Original Developer, or, for the eradication of melaleuca, remain the duty of the "bonded authority," if the Original Developer ever created such an entity, which appears highly doubtful. The documents likewise do not disclose the penalties for noncompliance. On June 16, 1988, the District issued a modification to the 1988 Permit for the construction and operation of a 110.9-acre residential development in Phase I, which occupies the central basin. On October 1, 1988, the United States Army Corps of Engineers (Army Corps) issued the Original Developer a permit to destroy 164 acres of wetlands on the 900-acre parcel. Special conditions of the 1988 Army Corps permit require the preservation of "115 acres of high quality wetlands," the creation of 18 acres of wetlands and 15 acres of littoral shelf, and the implementation of a "Melaleuca Eradication Program," which is the same program as is incorporated in the 1988 Permit. The 1988 Army Corps permit contains an attachment dated October 24, 1987. This attachment identifies the protected wetlands as the two large wetlands in the north parcel totaling about 40 acres, 58 acres in the 115-acre preserve, and 53.5 acres in the south parcel. The 1988 Army Corps permit protects several wetlands in the south parcel, including wetland numbers 14 (3.04 acres), 16 (1.6 acres), 23 (0.53 acres), 30 (2.6 acres), 44 (0.8 acres), 29 (1.08 acres), and 46 (3.0 acres). These wetlands, which total 12.65 acres, are seven of the nine wetlands partially preserved in the 1988 Permit, although some of the acreages vary from those preserved in the 1988 Permit. Unlike the District's permits (except for the subject proposed permit modification), the 1988 Army Corps permit addresses conveyances by the developer. The 1988 Army Corps permit states: "If you sell the property associated with this permit, you must obtain the signature of the new owner in the space provided and forward a copy of the permit to this office to validate the transfer of this authorization." Below the signature line of the 1988 Army Corps permit is language stating: When the structures or work authorized by this permit are still in existence at the time the property is transferred, the terms and conditions of this permit will continue to be binding on the new owner(s) of the property. To validate the transfer of this permit and the associated liabilities associated with compliance with its terms and conditions, have the transferee sign and date below. On March 1, 1989, the Original Developer conveyed the 115-acre preserve to the Village, which later leased the preserve to the County. The Original Developer had not eradicated the melaleuca at the time of the conveyance, nor has anyone since done so. On August 17, 1990, water elevations in the wetlands in Phase I reached 19.4 feet NGVD, washing out construction pads, roads, and in-ground utilities. On September 7, 1990, the District issued a stop-work request because the SWM system was not working as required. On September 28, 1990, the District approved interim measures to preserve the wetland hydroperiod and allow for wetland overflow. These measures include berming the residential areas in Phase I/Plat I adjacent to wetlands. On June 13, 1991, the District approved additional modifications to the 1988 Permit and the construction and operations permit for Phase I and issued a conceptual approval for works in the north and central basins. The revisions to the conceptual approval include adding two control structures to the north wetland that connect to the water management system in the north basin and adding a berm around the smaller of the two preserved wetlands in the north parcel. The construction approval was for a perimeter berm along the south wetland and park areas. On June 24, 1992, the District issued a staff report recommending issuance of another modification of the 1988 Permit for the conceptual approval of a SWM system to serve the 900-acre parcel and approval of construction and operation of a SWM system to isolate and control the existing onsite wetlands and revise the control structure for the central basin. The staff report explains that this modification proposes berming the wetlands to the 100-year, three-day peak elevation. The staff report notes that the wetlands basin consists of 295.18 acres of wetlands, including 155.85 acres of “wetlands/uplands.” The staff report notes that the north basin contains 107.41 acres of “good quality wet prairie wetlands” with “minimal” melaleuca encroachment. The staff report restates that the purpose of the modification is to berm all of the wetlands and uplands not planned for development. Special Condition 19 requires the Original Developer to dedicate as conservation and common areas in deed restrictions the “wetland preservation/mitigation areas, upland buffer zones, and/or upland preservation areas," so that these areas are the “perpetual responsibility” of a named property owners’ association. Special Condition 22 states that “a wetland monitoring and maintenance program” and “a melaleuca eradication program” “shall be implemented,” but the condition does not expressly state by whom. Special Condition 22 requires that the work implementing these programs conform to these “approved environmental programs as outlined in the [1988 Permit].” Special Condition 25 provides that, on submittal of an application for construction approval in the south basin (Phase II), the "permittee shall submit a detailed wetland construction mitigation, monitoring and maintenance plan.” In evaluating the plan for approval, the District shall apply the “environmental criteria in effect at the time of construction permit application.” Although the approval of the District is not attached to the staff report, the District approved the June 24, 1992, staff report and proposed permit. The 1992 permit modification did not address the issue of who was responsible for melaleuca eradication after the sale of the property. On November 10, 1993, the staff report accompanying another request for a permit modification restates the special conditions of earlier permit modifications. Special Condition 23 restates the requirement that a melaleuca eradication program “shall be implemented,” again not stating by whom. Special Condition 23 now requires the completion of the melaleuca eradication program by February 25, 1994. The omission of a referenced exhibit to the permit from the exhibit filed in this case prevents a determination that this is the same as the Melaleuca Eradication Plan incorporated in the 1988 Permit and restated in the 1992 modification, although it probably is. In any event, Special Condition 23 concludes in another sentence lacking a stated or implied subject: “Maintenance of the preserved wetlands and berm planting areas shall be conducted in perpetuity to ensure that the conservation areas are maintained free from exotic vegetation (Brazilian pepper, Australian pine and melaleuca) . . ..” Although the record does not contain the written approval of the District to the staff report, the District approved the staff report dated November 10, 1993. On November 12, 1993, the Original Developer conveyed by special warranty deed the north to Petitioner. The deed is subject only to "easements, declarations, restrictions and reservations of record . . .." The record does not provide recording information for the deed. The Original Developer probably conveyed the south parcel to Applicant in the same fashion and at the same approximate time. Almost five months later, on March 29, 1994, the Army Corps issued another permit for the 900-acre parcel. Although the Original Developer had conveyed at least the north parcel, the Army Corps issued the 1994 permit to the Original Developer. The 1994 Army Corps permit authorizes the destruction of 158 acres. The general conditions governing transfers are the same as those in the 1988 Army Corps permit. The special conditions of the 1994 Army Corps permit require the permittee to preserve and enhance only 110 acres of high quality wetlands, instead of preserving 115 acres of such wetlands, as was required in the 1988 Army Corps permit. The 1994 Army Corps permit drops the requirement of creating eight acres of wetlands and 15 acres of littoral zone, as was required in the 1988 Army Corps permit, but requires the preservation of what appears to be the 39.5-acre preserve that is proposed by Applicant in the subject permit modification, as described below. Special Condition 3 of the 1994 Army Corps permit adds that all preserved areas "will be maintained in perpetuity free of Melaleuca. The permittee agrees to develop a bonded Melaleuca eradication program for the entire 906 acres. Copies of the bonded agreement will be provided to this office for approval before development can commence." The next permit activity affecting the 900-acre parcel is the subject application filed by Applicant on August 3, 1994, for its 503-acre parcel. On May 24, 1996, the District issued a staff report for conceptual approval of a SWM system proposed by Applicant for its 503-acre parcel. On June 13, 1996, the District issued an addendum to the staff report that contains another special condition that is not especially relevant to this case. In the background section, the staff report mentions the flooding of Phase I of the north parcel and states that the District had “assumed the adjacent wetlands would flow away from the development.” The staff report outlines the modifications implemented to eliminate the flooding; these modifications include connecting the M-1 canal, through inlets, with several wetlands located in the north and central basins. According to the staff report, Petitioner’s north parcel, which totals 287.34 acres, includes the Phase I/Plat 1 area, north basin, and part of central basin south of Phase I. Describing Applicant’s proposal, the staff report states that a preserve of 39.5 acres will be located in the northwest corner of the south parcel, adjoining the east boundary of the 115-acre parcel. The staff report states that the 39.5-acre preserve will sheetflow through cuts in the berm to wetlands in the 115-acre preserve. The 115-acre preserve is connected to the SWM system permitted on November 10, 1993, to eliminate flooding from these wetlands, whose control elevation is 19 feet NGVD. The staff report describes the south parcel as “dominated by flatwood habitat,” within which are stands of Australian pine and other exotic plant species that have recently been spreading across the site. The onsite wetlands are 4.93 acres of wet prairies, 18.4 acres of pond cypress strands, 1.56 acres of isolated marsh, 3.5 acres of cypress mixed with pine flatwood, and 163.91 acres of melaleuca. The staff report finds that only the 4.93 acres of wet prairies and 18.4 acres of cypress are in good condition, but melaleuca has become established in many of the wet prairies. The 1.56 acres of freshwater marshes and 163.91 acres of melaleuca are in poor condition. The 3.5 acres of cypress mixed with pine flatwoods are in fair condition. As for listed species, the staff report mentions only the possibility that herons might forage onsite during periods of standing water. Summarizing the impact of the proposed project on wetlands preservation, the staff report endorses the hydrologic reconnection of the 39.5-acre wetland/upland site with the 115-acre wetland. The staff report notes that water levels in the 115-acre preserve, which has been bermed to 21 feet NGVD, have stabilized at 19 feet NGVD. The staff report asserts that the “proposed wetland impacts (183.54 acres) were previously permitted under the conceptual permit application” for the original 1988 Permit. The staff report adds that this modification is to “change a portion of the original mitigation requirements . . . and includes impacts to a 6.78 acre wetland area that was previously permitted to be preserved.” But the staff report does not recommend the preservation of this wetland “[d]ue to the reduced hydrology and proximity to the proposed upland development” and the mitigation and compensation provided by the 39.5-acre preservation area. The staff report states that 8.76 acres of the 39.5- acre preserve are wetlands, and the remainder are uplands. As for the 8.76 acres of wetlands, the staff report lists 0.67 acres of mixed cypress and pine flatwoods, 4.93 acres of wet prairies, and 3.16 acres of cypress. Applicant would also restore 4.95 acres of pine flatwoods. As for the 183.54 acres of wetlands to be destroyed, the staff report lists 2.83 acres of mixed cypress and pine flatwoods in fair condition, 15.24 acres of cypress in fair condition, 1.56 acres of freshwater marshes in poor condition, and 163.91 acres of melaleuca in poor condition. Addressing the mitigation and monitoring elements of the current proposal, the staff report states that the modification would eliminate the creation of 15 acres of littoral wetlands around SWM lakes and 7.99 acres of marshes in golf courses in return for the creation of the 39.5-acre preservation area. The staff report assures that Applicant will perpetually manage and maintain the 115-acre preserve. Conceding that the 1988 Permit also required long-term maintenance of the 115-acre parcel, the staff report notes that the initial eradication effort was never completed. The staff report mentions an “access agreement” giving Applicant the authority to enter the 115-acre preserve for mitigation and monitoring, but “anticipat[es]” that Applicant will submit an application for another permit modification, on behalf of the two governmental entities, so that Applicant can “assume future maintenance responsibilities for this area.” As is clarified by the maintenance and monitoring plan, which is part of the proposed permit, Applicant's expectation is that the County and Village, not Applicant, will assume future maintenance responsibilities for the 115-acre preserve. The staff report concludes that the District should issue the permit subject to various conditions. Special Condition 1 is that the minimum building floor elevation is 20 feet NGVD. Special Condition 16 requires the implementation of a wetland mitigation program and requires Applicant to create 4.95 acres of marsh; restore 3.16 acres of cypress, 4.93 acres of marsh, and 0.67 acres of mixed forest; and protect 25.79 acres of uplands. Special Condition 17 sets performance criteria for the mitigation areas in terms of percentage and length of survival of vegetation. Special Condition 17 supplies completion dates for monitoring reports. Special Condition 21 addresses listed species. Noting that listed species have been seen onsite or the site contains suitable habitat for such species, Special Condition 21 requires Applicant to coordinate with the Florida Game and Fresh Water Fish Commission or the U. S. Fish and Wildlife Service for guidance, recommendations, or permits to avoid impacts to such species. The monitoring and maintenance plan does not address direct and contingent liabilities for maintenance and generally is a poor candidate for enforcement. In addition to the vagueness of the passive voice, the plan is, at times, simply unreadable, as, for example, when it concludes boldly, but enigmatically: The site as a whole is evolving hydrologic trends which permits successional seres development toward communities with shorter hydroperiods and ultimately, toward more upland transitional and/or exotic species dominance of historically wetland habitats. Long-term prospectives infer that successional deflection has become a severe detriment for natural environmental control to alter the present scenario. Active management coupled with graduated balanced in hydrologic restoration and created habitat elements will become the processes engineered to obtain an infusion of probabilities fashioned to inscribe a regenerative adaptation to the present site condition while fostering in situ processes, to optimize derived functions, for the maintenance of both habitat and wildlife over the long-term existence of the Preserve. (Sic.) Water Quality Impacts Petitioner does not contend in its proposed recommended order that the proposed project fails to meet applicable requirements regarding water quality. Applicant has provided reasonable assurance that the proposed permit modification would not violate State water quality standards. Flooding Petitioner contends in its proposed recommended order that the proposed permit modification would not meet applicable requirements regarding water quantity and flooding. However, Applicant has provided reasonable assurance that the project would not violate these requirements. There are several aspects to a SWM system. Undeveloped land stores and conveys rainfall through soil and surface storage. An artificial SWM system alters the undeveloped land’s storage capacity by the addition of a storage and drainage system, such as, in this case, conveying water through the soil into storm drains and then to lakes to store surface runoff prior to release, through an outfall structure, into a receiving body of water--in this case, the M-1 canal. The SWM system hastens the conveyance of stormwater runoff offsite. The control elevation of a SWM system is the height at which water in the lakes will flow through the outfall structure into the receiving body of water. Except during the dry season, the control elevation tends to establish not only the water level of the SWM lakes, but also of the nearby water table. The hastening of drainage offsite with the establishment of control elevations produce the drawdown effect of SWM systems. As to flooding, the basic underlying dispute between Petitioner and Respondents is whether to use the pre- or post- development depth to water table. In determining whether an applicant has provided reasonable assurance as to the impact of a proposed development on wetlands, one would project the effect of any post-development drawdown on the wetlands themselves and their functions and inhabitants. It would be illogical not to do the same in determining whether an applicant has provided reasonable assurance as to the impact of a proposed development on flooding. Pre-development, the average depth to water table on Applicant’s property is as little as two feet. Post- development, the average depth to water table on Applicant’s property will be five feet, which is the difference between the control elevation of 14 feet NGVD and ground elevation of 19 feet NGVD. Petitioner’s evidence concerning flooding is flawed because its expert witness based his calculations on an average depth to water table of two feet on Applicant’s property. He did not adjust for the considerable drawdown effect of the SWM system. The District table allows for no more than four feet between the water table and ground, so there is an added margin of safety in the ensuing flooding calculations. Another important factor in the flooding calculations is the soil type in terms of permeability. The District properly characterized the prevailing soils as flatwoods, and the soils onsite are in the category of “good drainage.” Applicant’s suggestion that flooding calculations use the post-development soils is rejected. Post-development depths to water table are used because they can be calculated to predict post-development conditions accurately. Applicant produced no proof that it would replace such massive amounts of soil from the site with more permeable soils so as to justify reclassifying the soil type. The District's flooding calculations probably overstate the risk of flooding in the three-day, 100-year design storm because they ignore lake bank storage, which is the additional amount of water that a lake can store in its sloped banks above the typical water elevation. The District could have relied on the effect of lake bank storage for additional assurance that the proposed project will not result in flooding. The proposed project contains a large number of long, narrow lakes, which will thus have a relatively high percentage of lake banks to lake area. Additionally, the District has raised the minimum floor elevation at this site by two feet over 18 years. Whatever other effects may follow from this trend, the higher floor elevation offers additional protection to onsite improvements. The flooding of Petitioner’s property seven years ago understandably is a matter of concern to Petitioner. Applicant proposes to change the configuration of drainage basins, but the District has adequately addressed the drainage issue, and this is not the first time in the 20-year permitting history of this property that the District has approved a reconfiguration of basins. Also, in the 1988 Permit, the District incorrectly projected the direction of runoff under certain conditions. However, the flooding was partly due to inadequate road- drainage facilities. Following the flooding, the Original Developer enlarged these features and bermed the flooding wetlands, so as to eliminate the flooding of developed areas due to design storm events. On balance, Applicant has proved that the proposed permit modification would not adversely affect flooding or water quantity. Environmental Impacts A. Wetlands Petitioner contends in its proposed recommended order that the proposed permit modification would not meet applicable requirements regarding environmental impacts to wetlands. Applicant has failed to provide reasonable assurance that the proposed work would not violate these requirements. There are two major deficiencies in the District's analysis of wetland impacts and mitigation or compensation. First, the proposed permit modification includes mitigation or compensation in the form of melaleuca removal. But prior permits have already required the same work, no one has ever done the work, and the District does not know if these permit requirements are still enforceable. Second, the proposed permit modification ignores 13.9 acres of preserved wetlands in the 1988 Permit, allowing their destruction without mitigation or compensation. The permitting process requires the District to balance the impacts of development and mitigation or compensation on the natural resources under the District's jurisdiction. Balancing these impacts in issuing the 1988 Permit, the District required the complete eradication of melaleuca in return for permitting the residential, institutional, and recreational development proposed by the Original Developer. District staff, not the Original Developer or Petitioner, called the Melaleuca Eradication Plan “the major environmental feature” of the development plan approved by the 1988 Permit. The major environmental feature of the 1988 Permit clearly justified significant development impacts on natural resources. To justify additional development impacts on natural resources, the District now proposes to count again another developer’s promise to eradicate the melaleuca. The District claims that the term of the original melaleuca protection plan was only ten years, not perpetual as is presently proposed. However, the District's claim ignores Special Condition 23 in the 1993 permit modification. This condition set a deadline of February 25, 1994, for the eradication of melaleuca and made perpetual the requirement that one or more of the potentially responsible parties--the Original Developer, Petitioner, Applicant, the bonded authority, the property owners' association, or transferees-- maintain the wetlands free of melaleuca and other exotics. Unfortunately, this “major environmental feature” of the 1988 Permit, as well as subsequent permit modifications, was so poorly drafted as to leave potentially responsible parties unsure of their legal obligations. The District tacitly suggests that it cannot enforce the obligations imposed by the 1988 Permits and later modifications for the eradication of melaleuca. But there is presently no reason for the District to resort again to permitting without first reviewing carefully its enforcement options. The District should first determine whether anyone will voluntarily assume these obligations. As a business consideration, Petitioner may choose to eradicate the melaleuca from the north parcel and 115-acre preserve to prevent Applicant from providing this service and claiming that it should receive compensation credit against additional environmental impacts permitted by a modification of the 1988 Permit. Maybe the County or Village has already budgeted funds for this work. If no party offers to perform the necessary work, the District must next determine its legal rights and the legal obligations of these parties. Depending on the results of this research, the District may need to consider litigation and the cessation of the issuance of construction and operation permits on the 900-acre parcel or either the north or south parcel. At this point, the District should discuss joint litigation or permit revocation with the Army Corps, whose 1994 permit requires the permittee to develop a bonded melaleuca-eradication program and apparently imposes on the permittee the responsibility to maintain all preserved areas free of melaleuca. Only after having exhausted these options may the District legitimately conclude that melaleuca eradication on any part of the 900 acres represents fair compensation for the development impacts on jurisdictional natural resources. The second major problem as to wetlands impacts concerns the calculation of wetlands acreages to be destroyed by the proposed permit. The 1988 Permit expressly incorporates the Wetlands Monitoring/Maintenance Program. This program, as an operative part of the 1988 Permit, represents that the developer will “partially preserve. . .” nine wetlands totaling 13.9 acres. The partial preservation of wetlands does not mean that a five-acre wetland will remain a five-acre wetland, except that its function will be impaired. Partial preservation means that, for instance, two acres of a five- acre wetland will be preserved. It is impossible for the District to have required mitigation to offset the destruction of these 13.9 acres of wetlands because the District denies that the 1988 Permit required the partial preservation of these nine wetlands. As noted below, neither the District nor Applicant can identify all of the wetlands that make up the 13.9 acres. Rather than account for these wetlands that were to have been partially preserved, the District instead contends that this undertaking by the Original Developer was ineffective or nonbinding because it was overriden by contrary statements in the staff report. Not so. The specific provisions delineating the preserved wetlands area in the Wetlands Monitoring/Maintenance Program, which was prepared by the Original Developer, override more general statements contained in the staff report accompanying the permit. There is not necessarily a conflict between the staff report and the Wetlands Monitoring/Maintenance Program. The staff report states that the plan “includes the protection of approximately 100 acres of the best quality wetlands,” together with the creation of eight acres of golf course wetlands and 15 acres of lake littoral zones. The plan “includes” these wetlands among those preserved or created; the word suggests that the list is not exhaustive, but only illustrative. Alternatively, if the list were exhaustive, the preservation of “approximately” 100 acres reasonably encompasses the 112.71 acres of partially or totally preserved wetlands cited in the Wetlands Monitoring/Maintenance Program. More to the point, on October 26, 1987, Donald Wisdom, the engineer handling the 1988 Permit, prepared a memorandum for the file stating that the total acreage of wetlands to be preserved or created was 134.45. This figure represents an insignificant deviation of 0.19 acres from the total listed in the Wetlands Monitoring/Maintenance Program, which was dated six weeks later, on December 8, 1987. In the October 26 memorandum, Mr. Wisdom describes the preserved wetlands as 111.46 acres of A- and B-quality wetlands. This is 1.25 acres less than the acreage in the Wetlands Monitoring/Maintenance Program. These small discrepancies were eliminated by November 18, 1987, when Mr. Wisdom wrote a memorandum noting that the program called for the total preservation of 98.81 acres and partial preservation of 13.9 acres. Adding the created wetlands, the new total for preserved or created wetlands was 134.64 acres. A month later, a District employee wrote a memorandum to the file, expressing his “main concern” that the proposed development would protect only 99 acres of wetlands. It is unclear why the employee mentioned only the 98.81 acres slated for preservation. Perhaps he was confused or mistaken. But the misgivings of a single employee do not constitute the rejection by the District of a developer's proposal to preserve nearly 14 acres of high-quality wetlands. The staff report for the 1988 Permit notes that the 900-acre site contained about 281 acres of wetlands. If the 1988 Permit required the preservation, as an entire wetland or part of a larger wetland, of 112 acres of wetlands, then the 1988 Permit allowed the destruction of 169 acres, which is consistent with the 164 and 158 acres allowed to be destroyed by the 1988 and 1994 Army Corps permits. However, by the 1996 permit modification, the staff report refers, without explanation or justification, to the permitted destruction of 183.54 acres of wetlands--evidently adding the 13.9 acres to the 169 acres previously permitted to be destroyed. Tab 13 of the Wisdom bluebook identifies the nine wetlands constituting the 13.9 acres, which are entirely in Applicant's south parcel. Except for three, all of these wetlands were characterized as A-quality, meaning that they are in good to excellent condition and “have not been stressed significantly from the biological viewpoint.” B-quality wetlands are in disturbed condition and “are in various stages of biological stress caused primarily by a lowered water table and/or melaleuca invasion.” C-quality wetlands are highly disturbed and “are substantially degraded biologically.” The 13.9 acres of wetlands comprise wetland numbers 23 (0.5 acres), 46 (0.4 acres), 44 (0.6 acres), 37 (0.4 acres), 29 (1.1 acres), 20 [sometimes misreported as 21] (3.9 acres), 30 (2.6 acres), 16 (1.5 acres), and 14 (2.9 acres). Wetland numbers 46 and 29 are B-quality, and wetland number 20 is C-quality. The wetlands shown in District Exhibit 4 and Applicant Exhibit 3 inaccurately portray the wetlands constituting the missing 13.9 acres. A internal memorandum to the file notwithstanding, the District predicated the 1988 Permit in part on the preservation of 112.71 acres of functioning wetlands, including the 13.9 acres that the District now disclaims. The mitigation and compensation required of Applicant in the present case ignored the destruction of these wetlands. The District's analysis of mitigation and compensation in this case was fatally flawed by these two deficiencies. But more deficiencies exist in the District's analysis of wetland impacts. The District relied on faulty data in reviewing Applicant's request for a permit modification. Undercounting the extent of wetlands by at least 21 acres and their condition by an indeterminable amount, Applicant presented to the District a materially inaccurate picture of the wetland resources on the south parcel. Despite disclaimers to the contrary, the District relied on this inaccurate data in reviewing Applicant's request for a permit modification. There are possible problems with 39.5-acre preserve offered by Applicant. This parcel contains less than nine acres of wetlands, including two wetlands that Applicant may already be required to preserve under the 1994 Army Corps permit. At the same time, Applicant's proposal may include the destruction of a third wetland that is to be preserved under the 1994 Army Corps permit. The best rendering in the record of the 1994 Army Corps permit may be Applicant Exhibit 4, which shows eight large wetland areas to be “preserved/enhanced/created.” Two of these are the 10- and 30-acre wetlands on Petitioner’s property, which were preserved in the 1988 Permit. Three of the eight wetlands are in the 115-acre preserve; these were also preserved in the 1988 Permit. The remaining three wetlands to be preserved, enhanced, or created under the 1994 Army Corps permit are in the north end of Applicant’s property. It is difficult to estimate acreage given the scale of the drawing, but the two westerly wetlands are about 4-5 acres each and the easterly wetland is 3-3.5 acres. Subtracting the total preserved acreage of 110 from the acreage identified in the preceding paragraph, the total acreage of these remaining three wetlands is about 12. The two westerly wetlands are in the 39.5-acre preserve that Applicant offers as mitigation in the present case. According to Applicant Exhibit 6, the easterly wetland, or at least the most valuable part of it--the center--is slated for destruction if the District grants the subject permit modification. The proposed destruction of the third wetland is a matter of greater interest to the Army Corps than to the District, but the offer to preserve the other two wetlands really does not provide anything in return for the permitted development impacts because these two wetlands are already preserved under the 1994 Army Corps permit. As the District and Applicant contend, golf course marshes and littoral zones are typically of little environmental importance. Although the 1988 Permit addresses some of these problems, although without supplying any performance standards, golf courses themselves are often conduits of fertilizers and pesticides into the groundwater and nearby surface water. The District and Applicant justifiably question the value of the golf courses approved in the 1988 Permit as wildlife corridors. It is unclear what wildlife would use the corridor, which is surrounded by residential development and bounded by Okeechobee Boulevard. Other factors also militate in favor of Applicant's proposal. But, as the record presently stands, there is no way to find that Applicant has provided reasonable assurance that the proposed development and related mitigation and compensation, as described in the subject permit modification, meet the applicable criteria. The District substantially undervalued the environmental impacts of the proposed modification while substantially overvaluing the environmental impacts of Applicant's proposed contributions in the form of mitigation and compensation. To find adequate assurance as to wetland impacts in these circumstances, where the District did not perform an informed balancing of various impacts in a large-scale development, would permit the District to transform the unavoidably imprecise task of balancing wetland impacts into an act of pure, unreviewable discretion. Listed Species The only relevant listed species onsite is the gopher tortoise, which is a species of special concern. Gopher tortoises use the site to an undetermined extent. Applicant's suggestion that someone brought the tortoises to the site is rejected as improbable. However, due to the resolution of the wetlands issue, it is unnecessary to determine whether Applicant provided reasonable assurance as to the value of functions provided to wildlife and listed species by wetlands. Procedural Issues A. Standing Petitioner has standing due most obviously to flooding considerations. Additionally, the SWM system permitted in 1988 is for the entire 900-acre parcel, of which Petitioner’s parcel is a part. Applicability of ERP Rules The proposed permit modification would substantially affect water resources. The proposed permit modification would substantially increase the adverse effect on water resources. Requirement to Delineate Wetlands Due to the resolution of the wetlands issue, it is unnecessary to determine whether Applicant met applicable requirements concerning the delineation of wetlands. Improper Purpose Petitioner did not challenge the proposed permit modification for an improper purpose. Relevant Provisions of Basis of Review The District revised its Basis of Review after the adoption of ERP rules. Although the order concludes that the District should have applied the ERP rules, and thus the ERP Basis of Review, the order shall discuss both versions of the Basis of Review because the District ignored numerous provisions of both documents in approving Applicant's request for a permit modification. Section 4.6 MSSW Basis of Review requires the District to consider "actual impact" to the site by "considering the existing natural system as altered by the proposed project[,]" including "positive and negative environmental impacts." Section 4.6 requires the District to "balance" these impacts "to achieve a reasonable degree of protection for significant environmental features consistent with the overall protection of the water resources of the District." The proposed permit modification fails to comply with several provisions of Appendix 7 of the MSSW Basis of Review, such as Sections 4.2 requiring a detailed description of the isolated wetlands to be destroyed; 5.1.1(d) favoring the protection of isolated wetlands over their destruction, mitigation, and compensation, which are considered "only when there are no feasible project design alternatives"; and 5.1.6 prohibiting the alteration of water tables so as to affect adversely isolated wetlands. The proposed permit modification also violates various provisions of the ERP Basis of Review. Section 4.0 of the ERP Basis of Review sets the goal of permitting to be "no net loss in wetland . . . functions." Sections 4.2 and following generally require balancing. Section 4.2.1 predicates District approval on a showing that the SWM system does not cause a "net adverse impact on wetland functions . . . which is not offset by mitigation." The ERP provisions first require that the District "explore" with an applicant the minimization of impacts prior to considering mitigation. Section 4.2.2.4(c) specifically imposes monitoring requirements for SWM systems that "could have the effect of altering water levels in wetlands." Sections 4.3.2.2 and following discuss mitigation ratios under the ERP Basis of Review. If the District can explicate a policy to count as mitigation wetlands acreage already preserved under Army Corps permits, the ratios in this case might warrant further consideration, assuming Applicant resubmits an application for permit modification. But it would be premature to consider the ratios on the present record for several reasons. The District has not proved such a policy. If such a policy counts such wetland acreage, on the theory that the District protects function and the Army Corps protects merely the wetland, the record is insufficiently developed as to the functions of the wetlands proposed for protection, as well as the functions of the 13.9 acres of wetlands proposed for destruction. Also, the District has not sufficiently explored project minimization, as is now required under the ERP Basis of Review.
Recommendation It is RECOMMENDED that the District enter a final order denying Applicant's request for a permit modification. ENTERED in Tallahassee, Florida, on June 13, 1997. ROBERT E.

The Issue The issue in this case is whether the South Florida Water Management District (SFWMD) should grant the application of Daniel Borislow, LLC, for an after-the-fact Environmental Resource Permit (ERP) and issue ERP 50-09272-P.
Findings Of Fact In 2007, Borislow bought 6.2 acres of land near the corner of Congress Avenue and Summit Boulevard in West Palm Beach. Borislow proceeded to create a soccer field on the property. The project required the addition of fill, the grading and leveling of the field and a shellrock driveway/parking area, and the installation of sod, an irrigation system, an exfiltration trench for water quality treatment, and lighting. Later in 2007, Borislow's activities came to the attention of SFWMD, which cited Borislow for conducting activities requiring an ERP without applying for and obtaining one. To resolve the enforcement action, Borislow agreed to apply for an after-the-fact ERP. Initially, SFWMD estimated primarily from aerial photography that 0.71 acres of wetlands were filled and impacted. During the permitting process, SFWMD's estimate of direct wetland impacts was reduced to 0.50 acres, and the mitigation required for direct and secondary2 wetland impacts was determined using the Wetland Rapid Assessment Procedure (WRAP).3 It was determined that Borislow's purchase of 0.2 of a freshwater herbaceous wetland credit in the Loxahatchee Mitigation Bank would offset the project's wetland impacts. SFWMD staff determined that all ERP criteria were met.4 Spots stipulated that there are no water quality issues, that no wetland-dependent endangered or threatened species of special concern have been observed at or in the area of the project site, and that the potential use of the site by such species is minimal.5 Spots contends: SFWMD underestimated the extent of impacted wetlands (and, therefore, the amount of mitigation did not offset the wetland impacts); reasonable assurance was not given that the project will not flood the Spots property to the north, in violation of permitting criteria in Florida Administrative Code6 Chapter 40E-4 and SFWMD's Basis of Review for ERPs (BOR); and reasonable assurance was not given that water storage and conveyance capabilities would not be adversely impacted, in violation of the permitting criteria in Rule Chapter 40E-4 and the C-51 basin compensating water storage requirements of Rule Chapter 40E-41, Part III. In normal permitting, existing wetlands are delineated in accordance with Rule Chapter 62-340. In this after-the-fact permit application, former wetlands had to be estimated. Spots reasonably contends that Borislow should not benefit from having filled wetlands without an ERP. But the evidence proved that the former wetlands on the Borislow property were properly estimated. Contrary to the contention of Spots, the wetlands were not estimated on the basis of a single aerial photograph. There were numerous aerial photographs over several years, which the experts could interpret and use to make a reasonable estimate of the extent of the former wetlands on the site. Ironically, while criticizing SFWMD's alleged reliance on a single aerial photograph to determine the extent of the former wetlands, Spots relied on a single aerial photograph to claim that the former wetlands on the Borislow property were deep and larger than 0.5. acres. The photograph appeared to show standing water only on the Borislow property, but it is possible that standing water on the Spots property was obscured by vegetation. In addition, it is impossible to determine the depth of the water from the aerial photograph, and there was no evidence as to the rainfall preceding the aerial photograph. Spots provided no other evidence to support its claim that more mitigation is needed to offset the wetland impacts. On the issue of flooding the Spots property, the evidence was clear that, contrary to the drawings in the ERP, the highest elevations in the northwest corner of the Borislow property are several feet south of the Borislow/Spots property line,7 and several feet higher than the elevation at the property line,8 causing surface water to flow down this slope from the Borislow property onto the Spots property. The evidence proved that no such "back-flow" existed in that location before the project. This "back-flow" can be prevented from crossing the property line by placing a swale or railroad tie or some other similar vertical retaining wall near or on the property line. Borislow has agreed to an additional ERP condition that this be done. The Borislow property is in sub-basin 30 of the C-51 basin. Spots and its engineering expert criticized the engineering calculations used by the experts for Borislow and SFWMD to provide reasonable assurance that the project did not result in a net decrease in water storage capacity in the basin. Spots contended that the calculations incorporated pre- development elevations taken from a 2005 aerial photograph. However, the more persuasive evidence was that the elevations used in the calculations actually came from survey information on surrounding properties, including the Spots property and Summit Boulevard, plus the control elevation in nearby Lake Worth Drainage District L-5 Canal. Elevations for the former wetlands on the Borislow property were assumed to be 10 feet NGVD9 based on the actual elevations of the existing wetlands on the Spots property. The testimony of the experts for Borislow and SFWMD as to the source of the elevations used in the calculations is accepted. The engineering calculations developed by Borislow's expert and accepted by SFWMD indicated a net increase in water storage capacity as a result of grading and leveling the property.10 The calculations compared pre-development and post- development storage capacity between the water table11 and the 100-year storm elevation, which was calculated to be 14.1 feet NGVD. The evidence did not adequately explain how grading and leveling the Borislow property would increase water storage; it would seem that no change in water storage would result. The engineering calculations assumed that no fill was deposited on the property. However, the evidence was that 150 to 300 truckloads of fill, each with 17 to 18 cubic yards, for a total of 2,625 to 5,250 cubic yards, were delivered to and placed on the property. If 300 truckloads were used, this would represent as much as an acre-foot of fill.12 Although the fill would have some water storage capacity, adding that much fill to the property logically would result in a net decrease in water storage capacity in the C-51 basin. This loss was not quantified, or compensated.13 Borislow testified that the fill was used to construct a 13-foot high, 330-foot long, 30-foot wide berm along the western perimeter of the property and another large berm along the northern and southern perimeters of the soccer field.14 But other evidence does not support Borislow's testimony. According to the drawings in the ERP, there are a total of 370 feet of berms, which are required to be a minimum of six inches high to maintain elevation 13.4 feet NGVD to contain the peak stage of a 10-year, 3-day design storm.15 Based on the ground level photographs in evidence, the berms do not appear to be anywhere near 13 feet high or 30 feet wide. In any event, the evidence does not prove that the fill deposited on the property was higher than 14.1 feet NGVD. Regardless of the exact dimension of the berms, it appears that the fill was deposited in a way that would result in a net decrease in water storage capacity in the C-51 basin. SFWMD seems to suggest in its PRO that the fill should be disregarded because there were no records to confirm the dates it was delivered, or the amounts delivered, and because it might have been delivered to an adjacent property.16 But the burden of proof was on Borislow. See Conclusion of Law 16, infra. There was no evidence to prove that Borislow had the fill deposited on an adjacent property. It is more likely that the fill was deposited on the Borislow property in large part to fill the former wetland, which probably was lower than 10 feet NGVD. Spots also charged that Borislow's project essentially obstructs the previous flow of surface water from the wetlands on the Spots property into the wetlands on the Borislow property, such that surface water now backs up on the Spots property. This appears to be true. Since it appears that the wetlands on the Borislow property were lower than the wetlands on the Spots property, grading and leveling would have that effect; adding fill would exacerbate the effect. Spots also argued that the evidence did not provide reasonable assurance on the ability of Borislow's system to recover from a 10-year, three-day storm event, so as to be able to again retain the surface water runoff from a successive storm of that magnitude and duration 12 days later. But the persuasive evidence was to the contrary, primarily due to the major drainage features in the vicinity--namely, the C-51 and the L-5 canals.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that SFWMD deny Borislow's after-the-fact ERP. DONE AND ENTERED this 10th day of August, 2010, in Tallahassee, Leon County, Florida. S J. LAWRENCE JOHNSTON Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 10th day of August, 2010.
The Issue Whether Respondent Neal Colley should be issued a permit to fill certain wetlands located within the regulatory jurisdiction of the Department of Environmental Regulation.
Findings Of Fact The Department of Environmental Regulation is the agency with regulatory jurisdiction over the subject matter of this case, pursuant to Chapter 403, Part VIII, Florida Statutes, and related administrative rules. On or about October 19, 1989, Neal Colley (hereinafter "Colley") filed his Permit Application No. 571717171 with the Department of Environmental Regulation (hereinafter "DER") seeking a permit to fill wetlands located within the regulatory jurisdiction of the Department. Colley's application was related to a residential development identified as the Deer Point subdivision located in Gulf Breeze, Florida. As proposed in the application, the subdivision would contain 0.91 acres of fill in jurisdictional wetlands, 31 buildable lots and a 31 slip marina. The site of the development is adjacent to Pensacola Bay and Santa Rosa Sound, Class III waters. In February, 1990, Colley modified the application by deleting the proposed marina. Colley also proposed to fill on an additional 14 lots, bringing the total of jurisdictional wetlands fill to 2.8 acres. On July 6, 1990, subsequent to review of the application, the DER published notice of it's intent to deny Colley's application. The DER based the action on Colley's failure to provide reasonable assurances that the project would not result in significant wetlands habitat loss and water quality degradation. Colley filed a request for administrative hearing challenging the intent to deny the application. 1/ Thereafter, Colley and the DER discussed several amendments to the application directed at meeting the DER's objections to the original application. On or about August 20, 1990, Colley modified the proposed development by reducing the total number of lots to 31 and reducing the fill required. Colley further agreed to other conditions designed to otherwise mitigate the apparent adverse impacts of the project. In determining the acceptability of a mitigation proposal, the DER weighs the proposal and assigns "credit" for the mitigation proposal which provides a quantifiable method of evaluating a mitigation proposal. For example assignment of a 1 to 1 ratio indicates that there must be one acre of "mitigation" for every one acre of fill. In this case, the combined mitigation credit would allow the filling of 2.16 acres of fill. In his mitigation proposal, Colley reduced the amount of fill for which permission is sought to 2.14 acres in jurisdictional wetlands. This is the minimum which will provide Colley with an economically acceptable number of buildable lots. As onsite mitigation, Colley agreed to convey 29.2 acres of high quality wetlands adjacent to the existing public "Shoreline Park" to the City of Gulf Breeze for preservation as an additional public park. Of the 29 acres, 9 are jurisdictional wetlands which the DER assigned a mitigation ratio of 70 to The remaining 20 wetlands acres were assigned a mitigation ratio of 50 to 1. The application of the mitigation ratios to the 29 acres results in credit of .50 acres of fill. Colley also agreed to offsite mitigation in the form of preservation of 46 acres of high quality jurisdictional wetlands at Innerarity Island, to be conveyed by Colley to the University of West Florida. The DER assigned a mitigation ratio of 100 to 1, resulting in a credit of .46 acres of fill. Colley further agreed to onsite creation of 1.47 acres of marsh. The marsh creation plan provides for scraping down the land surface between two existing wetlands areas and planting the scraped surface with wetlands vegetation consistent with the vegetation found in the existing wetlands. Based upon the location of the wetlands creation and the availability of suitable vegetation for transplantation, there is a substantial likelihood that the created wetlands will function successfully. The DER assigned a mitigation ratio of 1.25 to 1, resulting in a credit of 1.2 acres of fill. The DER staff, both locally and in Tallahassee, reviewed the amended project and determined that the proposal, as amended, was acceptable under the DER's standards. The DER gave notice of it's intent to issue the permit for the amended project proposal. The greater weight of evidence establishes that the amended project will not violate water quality standards. In the short term construction phase, the permit requires sequencing of construction and use of hay bales and other turbidity screens to prevent discharge of runoff into the adjacent wetlands. In the longer term, post-construction phase, the project utilizes a system of retaining walls and buffer swales which are designed to prevent direct discharge of stormwater into the wetlands areas. The project permit requires utilization of best management practices and design standards which should operate to prevent violation of water quality standards. The greater weight of evidence establishes that the amended Colley project is not contrary to public interest. The preservation of a total of 75 acres of high quality wetlands by conveyances to the City of Gulf Breeze and the University of West Florida eliminates further development pressure in the parcels, and is clearly in the public interest. The evidence fails to establish that the project will adversely affect the public health, safety, or welfare or the property of others. There is no evidence that the project will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitat or that the project will adversely affect the fishing or recreational values or marine productivity in the vicinity of the project. The biological impacts of the amended project are minimal. There is no evidence that endangered or threatened species habitat in the area. There was anecdotal testimony related to adverse impacts on fishing allegedly resulting from other development. However, the evidence is insufficient to establish that this project will adversely affect fishing. There is sporadic water exchange between the surrounding bays and the interior wetlands, likely caused by periods of high rainfall which result in outflows of water from the wetlands into the bays. Water flowing from the bays to the wetlands may occur on occasion, however, water salinity samples taken immediately prior to the hearing showed, at most, minimal salinity in the wetlands. The types of vegetation and marine organisms within the wetlands are more common to fresh water areas than to salt water marsh. There is no evidence that the project will adversely affect navigation or the flow of water or cause harmful erosion or shoaling. The permanent nature of the project and the wetlands preservation conveyances provide a public benefit and are in accordance with the mitigation criteria. The existing wetlands to be preserved are acknowledged to be of high quality. Considering the site and existing vegetation adjacent to the location of the proposed 1.47 acres of created wetlands, the probability for success of the created wetlands area is substantial. It is highly likely that the created wetlands will provide the same conditions and functional values as the impacted wetlands. There is no evidence that the project will adversely affect or will enhance significant historical and archaeological resources. The evidence establishes that the adverse impacts which led to the DER's original determination not to permit the project, are either eliminated by the modification of the project or are offset by the mitigation plan which is part of the modified project. As to the cumulative impacts of the project, the onsite preservation proposal results in providing permanent protection for a 29 acre wetlands parcel which could otherwise be permitted for development. Outside this project, including the 29 acre wetlands mitigation area, there are few undeveloped lots remaining in the Deer Point area which contain jurisdictional wetlands. Prior to development on these lots, permits would be required. The lots would be required, on a case-by-case basis, to meet dredge and fill standards, and could be required to mitigate adverse impacts if such exist. The evidence establishes that the Colley project adequately mitigates any cumulative impact directly or indirectly related to this project. At hearing, the Petitioner failed to testify or otherwise offer evidence that would support a finding that Petitioner is substantially affected by the DER's proposed issuance of the permit for Colley's Deer Point Subdivision.
Recommendation Based on the foregoing, it is hereby recommended that the Department of Environmental Regulation enter a Final Order dismissing the petition of Linda L. Young and granting permit number 571717171 to Neal Colley. RECOMMENDED this 10th day of May, 1991, in Tallahassee, Florida. WILLIAM F. QUATTLEBAUM Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 10th day of May, 1991.
Findings Of Fact The Intervenors filed an Application for Dredge and Fill Permit with the Department of Environmental Regulation. The Department entered a notice of its intent to issue a permit. Petitioner requested a formal administrative hearing. The Department forwarded the matter to the Division of Administrative Hearings, where it was given Case No. 82-3155. A Recommended Order which includes Findings of Fact and Conclusions of Law has been entered in Case No. 82-3155. The Findings of Fact and Conclusions of Law set out in the Recommended Order are hereby incorporated into this Final Order and constitute a part of this Final Order. The Petitioner is an association of home owners within a residential development known as "Caloosa." Intervenors are seeking to develop an industrial park on land adjacent to the Caloosa development. Surface and ground waters from the proposed industrial park would drain toward Caloosa. Prior to the Department's entry of the notice of intent to issue a permit to Intervenors, the Department's personnel evaluated the application in free-form proceedings. An environmental specialist who works with the Department as a permit processor proposed to deny the application on account of the fact that Intervenors proposed to fill approximately 70 acres of wetlands, 24 of which were within the Department's permitting authority under Rule 17-4.28, Florida Administrative Code. The administrator of the Department's Dredge and Fill Permitting Section came to the conclusion that denial of the application could not be justified. He felt that the wetlands to be filled served only marginally to preserve water quality in the area. The Intervenors had proposed to artificially create wetland areas in order to compensate for the loss of filled wetland areas. The program administrator suggested to the permit processor that they negotiate to get the Intervenors to create additional artificial wetlands in order to mitigate against any possible adverse effect from the loss of natural wetland areas. These negotiations occurred, and the Intervenors agreed to increase artificially created wetland areas. The Department of Environmental Regulation does not have a rule which provides that its personnel can engage in negotiations respecting a permit application. Negotiations are, however, an inherent part of a permitting process. The Department does not have any written or unwritten policy whereby it accepts such mitigating factors as artificially created wetlands as justifying the filling of natural wetlands. It does not appear that the Department has any rule or nonrule policy concerning mitigation or trade-offs, and it does not appear that the Department has ever had such a rule or policy. The Department does not have a policy of accepting concessions, trade-offs, or mitigating factors so as to allow an applicant to violate the Department's water quality standards. Since there has been a permitting process, such factors as artificially created wetlands have been considered by the Department in determining whether an application meets the Department's criteria for issuance of a permit. The Department's policy is to consider whether an applicant has provided reasonable assurance that the short-term and long-term effects of proposed activities will not result in violations of water quality standards, as required under Rule 17- 4.28(3), Florida Administrative Code. If an applicant has proposed to construct artificial wetlands, the Department would logically consider it in making determinations about granting the permit. There is no evidence in the record of this proceeding from which it could be concluded that the Department has any unpromulgated "mitigation" policy which has the effect of a rule.
