Findings Of Fact The Petitioner is the owner of Lot 22 at Hatch Bend Upon Suwannee, a subdivision platted and recorded in 1979. Lot 22 lies at river mile 59 of the Suwannee River, as determined by the Suwannee River Water Management District. The Petitioner purchased the property for a site to construct a residence for his retirement. He desires an OSDS to serve a small dwelling which he proposes to construct on the site of approximately 1,000 square feet. The lot is two acres in size. The subject lot is high, level and well drained. In depth, it extends approximately 600 feet from the shoreline of the Suwannee River, upon which it has approximately 150 feet of river frontage. The lot is not subject to frequent flooding, however, as established by a registered land surveyor, the grade elevation of the lot is approximately 19.7 feet above mean sea level ("MSL"), with a benchmark elevation of 20.20 feet at the highest point. The ten-year flood elevation for river mile 59 was established, through information derived from the records of the Suwannee River Water Management District, and in evidence, to be 24 feet above MSL. Thus, the surface of the property involved and the septic tank system installation site lies beneath the ten-year flood elevation. The property, in other particulars, appears to comply with the statute and rules governing requirements for the grant of OSDS permits. That is, the water table level was shown to be more than 72 inches below the surface of the property, which is more than adequate in terms of separation of the proposed drainfield trenches from the ground water table. The soil lying beneath the property is "fine sand", which is a limited soil of an appropriate type for the successful functioning of an OSDS. Based upon mottling found in the soil, the water table during wet seasons is estimated to be at 72 inches below the surface, again, a more than adequate separation between the water table during wet seasons and the bottom of the proposed drainfield trenches. Thus, the subject site is amenable to the installation of an OSDS, but for the fact of its elevation beneath the required ten-year flood elevation. In terms of establishing entitlement to a variance from the subject rule concerning the prohibition of installation of drainfield trenches which will be subject to flooding based upon the ten-year flood elevation, the Petitioner offered no real concrete evidence. The Petitioner merely testified that it was a hardship for him not to be able to construct his proposed retirement home on the property because of the inability to obtain an OSDS permit; however, he did not establish that there were no reasonable alternatives to the normal OSDS proposed and applied for, as for instance, a mounded system so that the drain fields could be installed above the ten-year flood elevation or some other alternative sewage disposal and treatment system. Thus, the Petitioner did not establish that no reasonable alternative exists but to install the normal OSDS, nor did the Petitioner establish that installation of such a system beneath the natural grade would pose no threat to the public's health or the health of the Petitioner. The Petitioner did not establish that such a system would not pose an adverse impact on surface and ground waters in and in the vicinity of the proposed installation site. Thus, no entitlement to a variance from the permitting requirements in the statute and rules cited below was established. The Respondent takes the position that the variance and the permit application should be denied because the proposed installation site lies below the ten-year flood elevation, and, as the Respondent interprets the Governor's Executive Order No. 90-14, issued on January 17, 1990, which adopted Suwannee River Task Force Report Recommendation NO. 36 by reference, the variance request and the permit application should be denied because that Executive Order and the Report Recommendation it incorporates, in essence, calls for the prohibition of any installation of such systems below the ten-year flood elevation based upon a presumption that such would adversely affect public health and the ground and surface waters. The Respondent takes the position that it cannot discretionarily grant variances in such a situation because of the Executive Order.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that the application of Vernon Merritt for an OSDS permit and for a variance from the above-discussed permitting requirements, be denied.

The Issue The issue to be determined in this proceeding concerns whether the applicant has provided reasonable assurances that the proposed bridge project will meet the requirements of Chapter 403, Florida Statutes, and the various provisions contained in Title 17, Florida Administrative Code, so that a dredge and fill permit should be issued. More specifically, the issues concern whether the various water quality standards embodied in Title 17 of the Code and Section 403.918(1), Florida Statutes, will be complied with and whether the public interest standards in Section 403.918(2), Florida Statutes, will be met in the sense that the project can be assured not to be contrary to those standards.
Findings Of Fact Taylor County, through its duly-elected representative body, the Taylor County Commission, has filed an application seeking authority, by the grant of a "dredge and fill permit", to place fill material and to perform construction of a bridge across an unnamed canal in Taylor County, Florida, in the vicinity of Keaton Beach. The proposed bridge would connect Balboa Road and Marina Road on Pine Island in the community of Keaton Beach. Pine Island is an elongated strip of land separated from the Taylor County mainland by water and lying generally in a north/south direction. It is an artificial island created by dredge spoil from dredging activities by which certain canals were constructed during the decade of the 1950's. It is bounded on the west by what is known as "Main Canal", on the north by an unnamed canal, and on the east by what is known as "Back Canal". South of Pine Island is an inlet of the Gulf of Mexico. The canals involved in this proceeding, named above, are Class III waters of the State of Florida. Marina Road runs down the center of Pine Island. Lots to the west of Marina Road abut Main Canal and lots to the east of that road abut the Back Canal. Pine Island has been platted into approximately 110 lots. There were 47 homes and two (2) trailers on Pine Island at the time of the hearing. Only 17 full-time residents live there. Keaton Beach Road, also known as County Road 361, runs in a north/south direction generally and relatively parallel to Marina Road on land lying across Main Canal from Pine Island. In the past, Pine Island Drive connected Keaton Beach Road and Marina Road. It traversed Main Canal over what was known as the "humpback bridge", a wooden structure. The bridge ultimately became decayed and hazardous so that it was removed by the County in 1983. East of Pine Island, forming a continuation of Pine Island Drive, is a limerock road. This road presently provides the only vehicular or pedestrian access to Pine Island. It crosses the Back Canal over a culverted-fill area, making a 90 degree turn to the north and runs north along Back Canal. It then turns in an easterly direction until it meets Balboa Road. The property to the east of the center line of Back Canal and to the east of Balboa Road belongs to Dr. William Kohler. Other than the one-half of the culverted-fill area that lies west of the center line of Back Canal, the limerock road is on Dr. Kohler's land. In 1974, Taylor County was concerned about the use of the humpback bridge by school buses. It asked Dr. Kohler to grant it an easement over the limerock road for use by school buses. That limerock road passes over portions of Lots 44 and 45. Although Lots 44 and 45, east of Balboa Road, were not included in the written easement, Dr. Kohler has allowed use of the limerock road that passes over portions of Lots 44 and 45 since that time. Balboa Road presently terminates in a cul-de-sac at the edge of the unnamed canal that bounds the north end of Pine Island. On Pine Island, Marina Road is paved at the present time past the front of and to the northern property boundary of Lot 13, Petitioner Brumbley's residence lot. At that point, Marina Road ends at the south side of an unnamed dirt road. Between the north side of that unnamed dirt road and the unnamed canal lie Lots 2-6. The proposed Balboa bridge will start at the end of Balboa Road, cross the unnamed canal, cross a portion of Lot 2 and 3 on Pine Island, and tie into the existing grade at the "T" intersection where Marina Road deadends into the unnamed dirt road. The unnamed canal runs approximately east and west at the location of the proposed bridge. The bridge would be constructed on top of revetted fill material that will be placed to the north and south of a 15-foot wide span over the middle of the unnamed canal. The bridge construction shall be according to the Florida Department of Transportation specifications for road and bridge construction. The bridge will have a DOT approved guard rail on each side. No water quality violations will result from the proposed project. Turbidity violations may occur on a temporary basis during construction and so turbidity screens and silt barriers will be installed by the applicant to prevent such turbidity from migrating away from the site itself. A condition on the grant of the proposed permit has already been agreed to by the Respondent parties which will require turbidity and erosion-control devices prior to any excavation or placement of fill material. Specific condition eight also requires that these control devices remain in place until the fill has been vegetatively stabilized after construction is over. The proposed project will have a positive impact on public safety and welfare by providing proper and appropriate access to Pine Island by a more stable, safe roadway to which the bridge will be connected. During periods of high water, the present limerock access road floods, limiting emergency access to the Island. On one occasion, an injured person had to be carried down the limerock road to meet an ambulance at another location because the ambulance was unable to traverse the flooded limerock road. It is Dr. Kohler's intention to terminate use of the limerock road by members of the public since it is on his property. When that occurs, there will be no access to Pine Island unless the proposed bridge is built. The present limerock access road can be dangerous and slippery when wet, and persons using the limerock road often travel "dangerously fast", as testified to by Petitioner, Doris D. Brumbley. The 90-degree turn of the limerock road has no guardrails. The proposed project will, to a minimal, temporary degree, adversely impact fish or wildlife and their habitats, marine productivity and the current condition and relative value of functions being performed by the area affected by the proposed bridge. The canal system was originally excavated out of the salt marsh. Being man-made structures, their sides have slumped somewhat and have established a small, littoral zone where vegetation grows. Mud flats at the bottom of the canal bank allow the growth of oysters. The fill area associated with the proposed bridge, however, will have a surface area and volume comparable to the culverted fill that will be removed at the point where the road presently crosses Back Canal. When the culverted-fill area or plug across Back Canal is removed, the lost vegetation and oysters will become re- established at that location, offsetting the loss that will occur at the location of the bridge. Various marine species will also become established on and benefit from the shelter of the bridge and its structure, as well. The project will not cause harmful erosion or shoaling. The banks that will result from the removal of the culverted fill and the sides of the filled areas associated with the bridge will be protected from erosion with vegetation and revetments. The proposed project will enhance the flow of water in Back Canal and will improve navigation and flushing. Water flow through the existing culvert is presently considerably restricted when compared to the water flow beneath the proposed Balboa bridge area. The existing culvert is not at the bottom of the filled area. Therefore, at low water, most of the culvert is exposed, precluding the culvert from functioning at maximum capacity to aid in flushing with the water quality benefits caused by flushing being thus retarded. The lack of water flow has caused a portion of Back Canal, south of the culverted-fill area, to fill up with sediment. At low tide, parts of the Back Canal are without water. The increased flow that will result from removal of the fill plug and culvert where the road presently crosses Back Canal will allow property owners along Back Canal to navigate their boats out into the Gulf of Mexico, thus improving the recreational value of Back Canal and the navigation in the canal system. There are no similar fill projects planned for or expected in the Keaton Beach area. All three Petitioners are concerned that storm water runoff from the proposed bridge will flood their property, however. At the present time, the road in front of the Petitioners' lots is paved, with the pavement ending at the northernmost end of the Brumbley property. Since the Petitioners' lots already receive roadway runoff from the existing paved road, any increase in runoff to their lots would have to come from storm water flowing along the length of the road from the proposed project. The road which is to cross the proposed bridge will be composed of a 20-foot wide strip of asphalt, with 5-foot shoulders on each side. The slope from the crown of the road to the outer edge of the pavement will be one-quarter inch per one foot. The shoulders will have a slope of one-half inch per foot. Thus, rain water will flow off the sides of the road and down the shoulders, rather than down the length of the road towards the Petitioners' lots. Moreover, no additional water should be directed to the Petitioners' lots since the proposed road extension between the end of the bridge and the Petitioners' lots would be flattened. Water flowing off the bridge due to gravity will be shed toward the revetment which extends down to the canal, rather than towards the Petitioners' property. Storm water impacts will be addressed again by the Suwannee River Water Management District. A storm water permit application has been submitted to the Suwannee River Water Management District and is required before the proposed project construction can start. In that storm water permit application, the applicant acknowledged its obligation and responsibility to obtain all required permitting before construction starts. The draft permit reinforces this at specific condition six: "This permit does not constitute any approval of the storm water management system which must be obtained separately from the appropriate agency." All of the Petitioners are concerned about the increase in vehicular traffic which would pass in front of their lots and the Brumbley's particularly are concerned that light from headlights of increased traffic will be cast upon and into their house at night. It is clear that traffic passing the Petitioners' lots will increase due to the proposed project. It is equally clear from the angle of the bridge shown on Joint Exhibit 2 and the elevations of the bridge, shown on Joint Exhibit 3, that light from the headlights of vehicles approaching Pine Island after dark will illuminate, at least momentarily, portions of the Brumbley home.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that the application of the Taylor County Commission for the dredge and fill permit at issue, as described in the above Findings of Fact and Conclusions of Law, be granted on the terms and conditions set forth in the Department's draft permit, in evidence as Joint Exhibit 7.

Findings Of Fact The Petitioner is a political subdivision of the State of Florida. Respondent, State of Florida, Department of Environmental Regulation, is an agency of the State of Florida charged with carrying out the mandates of Chapter 403, Florida Statutes, and the rules contained in the Florida Administrative Code promulgated thereunder. Respondent, MRT, is a real estate investment trust organized under the laws of the State of Maryland and authorized to do business in Florida. Royal Oaks Development Corporation is a Florida corporation, a wholly-owned subsidiary of Maryland Realty Trust. MRT is developing a parcel of land in Sections 33 and 34, T-2-N, R-1-E, Leon County, Florida, and Section 4, T-1-N, R-1-E, Leon County, Florida, of which approximately 60 acres has already been developed as Royal Oaks Unit No. 1, a recorded subdivision pursuant to Chapter 177, Florida Statutes. The balance of the 120 acres is yet to be developed, and is the subject of this proceeding. The specific activity for which the application for dredge and fill permit was submitted consists of improvements to a drainage-way running from the south boundary of the MRT property to a pond designated in the application as "Pond II", together with a drawndown structure, referred to as "S-15". Following submittal of the permit application, DER notified MRT of the receipt of the application and advised that both a permit under Chapter 403, Florida Statutes and a license for stormwater discharge under Rule 17-4.248, Florida Administrative Code, would be required. Following review by the Department, during which MRT was notified that the application in its original form would not be received favorably, MRT, on August 21, 1980, revised its application and based on such revisions, the Department, on October 10, 1980, notified MRT of its intent to issue the permit and license sought. As indicated in the Intent to Issue, DER has asserted jurisdiction over the dredge and fill activities in question contending that they are contemplated to either be in or connected to "waters of the State". Specifically, the Department's Intent to Issue states as follows: The Department has permitting jurisdiction under Chapter 403, Florida Statutes, Section 17-4.28, Florida Administrative Code, and Public Law 92-500 over dredge and fill activities conducted in or connected to certain waters of the State. The specific pond in question and the pond to which it is connected constitute waters of the State over which the Department has dredge and fill permitting jurisdiction as defined in Section 17-4.28, Florida Administrative Code. The project is not exempt from permitting procedures. Pond II is approximately four acres in size and consists of a western lobe of approximately one acre. Pond II is connected to the north to a waterbody known as Pond III/Foxcroft Lake". The vegetation in the south portion of Pond III is typical of fresh water vegetation that grows in submerged or wet areas. The vegetation in an existing well-defined channel between Pond II and the proposed location of structure S-15 is also comprised of water-tolerant species. Sagittaria subulata was observed in the channel in the area proposed for location of S-15. This plant species cannot tolerate dry conditions, indicating that water is present in the channel under most conditions. Further, no upland or pioneer species were observed in the channel, which also is indicative of the fact that the channel usually contains water. Water flows from Pond II to Pond III approximately 90 percent of the time. The base flow in the channel is approximately 2 cubic feet per second. Based on the storage capacity of Pond II, it is probable that flow occurs out of Pond II into Pond III under most conditions. Although 88.0 feet mean seal level is the design normal pond elevation expected after construction of S-15, the present observable elevation of Pond II appears to be between 89.94 and 90.09 mean sea level. Observations of the types of vegetation surrounding Pond II supports the conclusion that the existing normal level of Pond II is approximately 90.0 mean sea level. Pond III is a waterbody of approximately four acres in size and is a portion of the continuation of a larger 10 acre body of water referred to in this proceeding as "Foxcroft Lake". Pond III was the subject of a prior Department dredge and fill permit in which it was determined that Pond III constituted waters of the State subject to the dredge and fill jurisdiction of the Department. Pond III/Foxcroft Lake is a lake owned by more than one person, of approximately 14 acres of surface area and a maximum average depth of approximately 3 feet. Pond III/Foxcroft Lake discharges to and is connected directly to a waterbody known as Long Pond. Long Pond in turn is eventually connected to and discharges into Lake Lafayette. Without any mechanisms designed to treat the pollutants expected to be generated by the proposed project, the development by MRT of its 120 acres of property could reasonably be expected to have a significant adverse impact on the waters of Pond II, Pond III and Foxcroft Lake. Scientific studies demonstrate that potential pollutants generated from developments - single family, multi-family and commercial - have a significant impact on receiving waters if not treated before discharged. The project as presently designed will correct an existing source of pollution by removing sediment which is entering Pond II from the south from Shannon Forest Subdivision. This sediment has been deposited in the drainage- way between Shannon Forest and Pond II and is damaging and severely stressing biota in the drainage-way. This sediment has filled a portion of Pond II and could be expected to eventually discharge into Pond III/Foxcroft Lake. The pre-development rate of flow off the project site as it presently exists is approximately 600 cubic ft. per second. The project as proposed will reduce the rate of flow by 50 percent, to approximately 300 cfs. The project incorporates five mechanisms or abatement controls to treat contaminants customarily contained in stormwater: a grassed conveyance system; retention of natural vegetated areas; energy dissipators; sediment traps; and added storage. Grassed conveyance systems treat stormwater by the assimulation by plant communities of dissolved pollutants, such as nutrients, and the deposition of suspended pollutants that have absorbed to the sediment particles. Approximately 50 percent of the conveyance system in the Phase II development will be grassed swales and re-vegetated ditches. As many swales as possible will be used to convey the stormwater from the discharge at the street outfalls to the ponds. The main drainage ditch through the property will also be grassed. Natural vegetated areas to be left around the existing ponds will treat stormwater by assimilation and filtration in the same manner as the grassed swales and ditches. A one-acre parcel of wetlands is to be left between the southern most portion of the drainage-way and Pond II as described in MRT Exhibit No. 8 and in the revised permit application of August 21, 1980. The vegetation downstream of Pond II between the pond and control structure S-15 will also be left intact. Virtually all the vegetation bordering Pond II and Pond III will be left in place. Five energy dissipaters are to be constructed upstream of Pond II. These structures are designed to reduce the existing sedimentation and erosion problems by reducing the energy gradient and allowing the deposition of sediment, upon which absorbed pollutants have attached, into the accompanying sediment traps. Sediment traps are also to be constructed upstream of Pond II. Sediment traps treat stormwater by reducing the velocity gradient. Sediment and the pollutants absorbed to the sediment will drop out due to insufficient velocity. Storage will be increased in Pond II by the construction of control structure S-15 and by the planned excavation of Pond II. Added storage has a beneficial effect on water quality in that it allows additional sediment particles to settle out, allows additional time for the vegetation on the edge of the ponds to assimilate dissolved pollutants such as nutrients, and reduces the peak discharge velocity. The project is in the public interest in that it will alleviate an existing stormwater problem. In terms of probable efficiency, physical needs and costs, the project represents the best available treatment alternative. Based on existing technology, the system designed for this project is the most effective system within reasonable costs. The effectiveness of the stormwater treatment system depends on the presence of vegetation and will require less maintenance and attendant costs. There does not presently appear to be any local government effort to implement stormwater controls to address this problem or source. Petitioner submitted no evidence of such local government efforts. The system proposed by MRT will mitigate not only the effects of the discharge generated by the proposed development of the 120 acres of property owned by MRT, but will also mitigate the effects of an existing source of stormwater pollution. The system, as designed, is sufficient to afford the Department reasonable assurance that stormwater quality standards will not be violated. The parties stipulated that, should the requested permit and license be issued, they should incorporate the following additional condition: Roads and drainage facilities are to be owned and maintained by Leon County. All paving and drainage shall be done in accordance with the County's standards, details and specifications. In addition, MRT has instituted civil litigation against Leon County concerning the property involved in this proceeding. One of the allegations of MRT's complaint is that Leon County has, through the action amounting to inverse condemnation, acquired a drainage easement over the property for which MRT is now seeking the dredge and fill and stormwater permits. The plans submitted to DER by MRT with its application contain the following: When the construction plans for Phase III of the Royal Oaks development are prepared, these plans shall be submitted to the Department for evaluation for compliance with the original stormwater review.
Findings Of Fact Background Petitioner, David E. Musselman, is the owner of Lot 23, Block 22, Cudjoe Gardens Eighth Addition, Cudjoe Key, Monroe County, Florida. The lot measures 127 feet along its front and rear property line, 135 feet along its side property lines and, similar to adjacent lots, its rear property line abuts an artificially created waterway. Currently, most of petitioner's lot enjoys an elevation of six feet; however, from the edge of the waterway landward a distance of approximately 20 feet [to what has been referred to as the "toe of the existing slope" in these proceedings] the surface consists of exposed caprock at an elevation of approximately four inches above mean high water. It is petitioner's desire to construct a single family residence upon such lot and, incident to such construction, to erect a seawall along the edge of the waterway such that the elevation at the waterway will be increased by two feet, and to backfill from the seawall to his home. Such backfilling would require the deposition of approximately 3,540 square feet of fill within the Department's jurisdiction, which was shown to extend from the edge of the waterway to the toe of the existing slope, and would raise the elevation in such area two feet above existing grade. On December 16, 1991, petitioner filed an application with respondent, Department of Environmental Regulation (Department), for an exemption from the Department's wetland permitting requirements. If approved, such exemption would allow petitioner to construct the vertical seawall along the waterway, and backfill from the seawall to his proposed home. By notice of agency action dated February 14, 1992, the Department proposed to deny petitioner's application predicated on its conclusion that his proposal did not meet the exemption criteria established by Rule 17- 312.050(1)(g), Florida Administrative Code. Petitioner filed a timely protest to contest the Department's conclusion. The exemption Pertinent to this case, Rule 17-312.050(1)(g), Florida Administrative Code, exempts from permitting the following activities: (g) Construction of seawalls or riprap, including only that backfilling needed to level the land behind the seawalls or riprap, in artificially created waterways where such construction will not violate existing water quality standards, impede navigation or adversely affect flood control. An artificially created waterway shall be defined as a body of water that has been totally dredged or excavated and which does not overlap natural surface waters of the state. For the purpose of this exemption, artificially created waterways shall also include existing residential canal systems . . . . At hearing, the parties stipulated that the waterway which abuts the rear property line of petitioner's lot is an artificially created waterway, as well as an existing residential canal, and that the proposed project will not violate existing water quality standards, impede navigation, or adversely affect flood control. Notwithstanding, the Department contends that petitioner's application should be denied because no need has been demonstrated that would support the construction of the seawall along the edge of the waterway, as opposed to locating it further inland, and therefore the amount of backfill, with its attendant loss of wetlands, is excessive. For the reasons set forth in the conclusions of law, the Department's position is untenable as a matter of law. 1/
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the Department enter a final order approving petitioner's application for an exemption to construct a seawall, and to backfill from such seawall to his proposed home, as applied for. DONE AND ENTERED in Tallahassee, Leon County, Florida, this 4th day of June 1992. WILLIAM J. KENDRICK Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 4th day of June 1992.
Findings Of Fact On November 1, 1982, Respondent Janson filed a Joint Application for a dredge and fill permit from Respondent, Department of Environmental Regulation, and from the Department of the Army Corps of Engineers. The project described in that application involved the construction of an approximately 1,000-square- foot, pile-supported residence, landward of the mean high water line but within the landward extent of Robinson Creek in St. Johns County, Florida. The proposed project also involved the placement of approximately 35 cubic yards of fill and a 30-foot culvert within a small (approximately 4-foot), tidally- influenced roadside ditch for driveway access and parking. The original application sought permission to place part of a concrete driveway and tool shed within the landward extent of Robinson Creek. The project is to be constructed on Lot 47, J.A. Lew Subdivision. Respondent Janson owns Lot 47, as well as Lots 45 and 46, which lots are north of and adjoining Lot 47 and also adjoining Robinson Creek. The next adjoining property owner to the north is the City of St. Augustine, Florida, which presumably owns the street. The adjoining property owner to the south of Lot 47 is Virginia P. Melichar. Neither Melichar nor the City objected to the Department's approval of the dredge and fill permit application. In support of his application, Janson retained the services of a registered surveyor and civil engineer, who performed a survey on Lot 47 to determine the location of the mean high water line with reference to the proposed project. That expert determined the location of the mean high water line to be at elevation 2.4 feet. Accordingly, all work contemplated by the dredge and fill permit is upland from the mean high water line. T.J. Deuerling, an environmental specialist for Respondent, Department of Environmental Regulation, visited the project site on December 13, 1982 and on December 30, 1982 in order to prepare the Department's Biological and Water Quality Assessment. As a result of those site visits, Deuerling recommended to Respondent Janson that he modify his permit application by moving the concrete slab and tool shed from the marsh area onto the uplands. Janson did so revise his application. In spite of the name of the permit being sought by Respondent Janson, the project involves no dredging. However, the culvert and its attendant fill would be placed in the man-made roadside ditch. That ditch constitutes a very weak transitional marsh. Although the culvert will eliminate some vegetation within that ditch, the effect of the elimination will be insignificant on water quality. The pilings for the pile-supported residence will also eliminate a small area of marsh. The anticipated shading caused by the pile-supported residence may impact somewhat on the vegetation in a small area below the residence; however, due to the fact that the floor of the house will be eight feet above the ground, light will still be able to penetrate. Therefore, the vegetation below the pile-supported residence will continue to act as a filter for pollutants. Janson has mitigated the small loss in wetlands by modifying his project so as to remove the concrete slab and tool shed from the marsh area to the uplands. Due to the project's small size, no storm water impact can be expected. Additionally, no evidence was introduced to show a violation of any water quality standard as a result of the proposed project. On March 16, 1983, Respondent, Department of Environmental Regulation, executed its Intent to Issue the dredge and fill permit in accordance with the revised application and subject to the conditions that: (1) turbidity curtains be employed in the ditch during the placement of fill over the culvert to contain any turbidity generated, and (2) construction on the uplands be confined to periods of normal water level conditions. On July 5, 1983, the Department of the Army Corps of Engineers issued its Permit and Notice of Authorization. The essence of the testimony presented by the Petitioners, including that of the employees of the St. Johns River Water Management District, who testified in opposition to the proposed project, is that even though Janson's proposed project would not impact water quality in a way that was either significant or measurable (although no one even suggested any specific water quality standard that might be violated), approval of Janson's permit might set a precedent for other projects which might then have a cumulative impact in some unspecified way at some unspecified location. No evidence was offered to show that Respondent, Department of Environmental Regulation's review of permit applications is other than site specific. Further, no evidence was introduced to show any proposed project anywhere having any impact with which Janson's project could be cumulative. Petitioners Sandquist and Shuler live in the neighborhood of the proposed project, perhaps as close as two blocks away.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered dismissing with prejudice the petition filed herein as to each individual Petitioner and issuing a dredge and fill permit to Respondent Janson in accordance with his revised application. DONE and RECOMMENDED this 13th day of January, 1984, in Tallahassee, Leon County, Florida. LINDA M.

The Issue The issues to be determined in this proceeding are: whether the challengers have standing; and (2) whether Proposed Rule 40E-8.221(2) is an invalid exercise of delegated legislative authority.
Findings Of Fact Based on the parties' stipulations and the evidence adduced at the final hearing, the following findings of fact are made: The Parties The District is a government entity existing and operating pursuant to chapter 373, Florida Statutes, as a multi- purpose water management district. The District has the power and duty to adopt MFLs consistent with the provisions of part I of chapter 373. Sanibel is a barrier island sanctuary in Lee County and a duly-formed municipality with a population of more than 6,000. Sanibel is situated at the mouth of the Caloosahatchee River, within the Caloosahatchee's greater estuarine area. Sanibel is known primarily for its natural beauty, including clear blue waters, shell beaches, world-class sport fisheries, and wildlife refuges. That is why tourists come from around the globe to visit Sanibel, and why Sanibel's residents move and remain there. Sanibel actively participated in the rulemaking process for the Proposed Rule from its inception. Sanibel submitted two technical comment letters to the District during the development of the Proposed Rule. Sanibel's natural resources director, James Evans, attended numerous public and technical meetings associated with the development of the Proposed Rule, speaking on the record at each of the public meetings prior to the adoption hearing by the District's governing board. The Town, located on Estero Island in Lee County, is also a barrier island community and duly-formed municipality with a population of more than 6,000. The Town is situated just south of the mouth of the Caloosahatchee River and on the southeastern edge of the Caloosahatchee River's greater estuarine area. The Town is known primarily for its natural beauty, including clear blue waters, shell beaches, world-class sport fisheries, and wildlife refuges. Cape Coral is a duly-formed municipality in Lee County and is the largest city between Tampa and Miami, with a population in excess of 150,000. Cape Coral is bordered on the south by the Caloosahatchee River and has over 400 miles of navigable canals and waterways, all of which are within the Caloosahatchee River's greater estuarine area. In addition, Cape Coral has an assigned load reduction allocation under the Basin Management Action Plan (BMAP) for the Caloosahatchee River Estuary (CRE) due to it being designated as impaired for dissolved oxygen and nutrients. Maintaining sufficient flow in the Caloosahatchee River would have a direct impact on Cape Coral's ability to meet its assigned load reduction allocation. In addition to living on or near the water, a substantial number of the residents of Sanibel, Cape Coral, and the Town engage in water-based recreational activities such as swimming, fishing, boating, kayaking, paddle boarding, bird watching, and nature observation in and around the Caloosahatchee River's greater estuarine area. Fort Myers is a duly-formed municipality in Lee County and has a population of approximately 80,000. Fort Myers is bordered by the CRE throughout its entire jurisdictional boundary. Fort Myers owns and maintains a yacht basin (Ft. Myers Yacht Basin), which includes a mooring field and an anchorage field in the Caloosahatchee River. Fort Myers presented testimony that commercial crabbing and recreational fishing have declined and that it has suffered economic harm due to water quality issues. Fort Myers owns the submerged land in the Caloosahatchee River from Marker 39 to Marker 58, and islands in the river. One such island will be used as a park for recreational activities such as canoeing, kayaking, and hiking for visitors to enjoy the Caloosahatchee River. Fort Myers also owns and operates piers and a public boat ramp within the Caloosahatchee River. Fort Myers' dock master has observed declines in seagrasses in the Caloosahatchee River during his 19-year career working at the Ft. Myers Yacht Basin. Fort Myers has adopted a Harbor Management Plan for the management of its mooring and anchorage fields in the Caloosahatchee River. Fort Myers has also been assigned a load reduction allocation under the BMAP for the CRE, and is responsible for a certain amount of pollution reduction over time. Bonita Springs is a municipality of more than 50,000 in Lee County. The borders of Bonita Springs include portions of Estero Bay, which, along with San Carlos Bay and the Caloosahatchee River, is part of the greater Lower Charlotte Harbor Estuary. Bonita Springs includes wildlife refuges, such as the Estero Bay Aquatic Preserve and Lovers Key State Park and Recreation Area. While Bonita Springs' strategic priorities include environmental protection and water quality, it does not have environmental staff or test water quality. Bonita Springs participates in Estero Bay Management and the Charlotte Harbor National Estuary Program (CHNEP). Bonita Springs provides financial assistance to the Caloosahatchee Citizen Sea Grass Gardening Project. Concerns regarding harm to the CRE and tape grasses are shared by a significant number of residents in Bonita Springs and Estero, including injury to the quality of life and recreational uses such as swimming, boating, and kayaking in the waterways. Estero is a municipality of more than 30,000 in Lee County. Estero borders the eastern portion of Estero Bay. Estero includes wildlife refuges, such as Estero Bay Aquatic Preserve and Koreshan State Park. While Estero has environmental policies, it does not have environmental staff or test water quality. Estero makes financial contributions to CHNEP. Estero is concerned that the Proposed Rule will affect its water quality, which could affect its residents' quality of life. Estero believes it could be harmed by poor water quality because its residents are portable retirees who can move away, or tourists who can choose not to visit. Captiva Island is situated at the mouth of the Caloosahatchee River, within the Caloosahatchee's greater estuarine area. CCP is a Florida not-for-profit corporation representing property owners, businesses, and the community of Captiva Island. Captiva Island is part of unincorporated Lee County and is located north of Sanibel. CCP has 200 financial contributors comprised of property owners, businesses, and residents on Captiva Island. CCP's mission includes protection of clean off-shore water, diverse and healthy marine life, and robust native vegetation along with the protection of mangrove fringe and water quality. CCP works with Lee County on provisions of the County's comprehensive plan, which include the quality of adjacent waters. CCP relied on the expertise of James Evans, the director of natural resources for Sanibel, and on the Sanibel- Captiva Conservation Foundation (SCCF). CCP was advised that the Proposed Rule was not sufficient to protect the environment and Vallisneria americana (Vallisneria) or tape grass during the dry season. Caloosahatchee River and Estuary The watershed of the Caloosahatchee River covers approximately 861,058 acres. The watershed consists of four sub-watersheds, three of which are upstream of the S-79 structure. The Tidal Caloosahatchee Basin sub-watershed (estuarine system) is downstream of the S-79 structure. The S-79 structure captures all the upstream discharges of fresh water that go into the estuarine system through the S-79 structure. Major tidal tributaries of the Tidal Caloosahatchee Basin are the Orange River and Telegraph Creek, which drain into the upper estuary downstream of the S-79 structure. Fresh water inflows from these and other tributaries also contribute fresh water into the estuarine system. The Caloosahatchee River was originally a natural watercourse running from its origin at Lake Flirt to San Carlos Bay. It is currently defined as the "surface waters that flow through the S-79 structure, combined with tributary contributions below S-79 that collectively flow southwest to San Carlos Bay." Fla. Admin. Code. R. 40E-8.021(2). Man-made alterations to the Caloosahatchee River began as early as 1884, but major alterations began in the 1930s with the authorization and construction of the C-43 Canal. The C-43 Canal runs 41.6 miles from Lake Okeechobee at Moore Haven, i.e., from the S-77 structure, to Olga, i.e., the S-79 structure. The C-43 Canal serves as a conveyance feature to drain water from the three sub-watersheds located upstream of the S-79 structure and convey regulatory discharges of water from Lake Okeechobee. In 1957, the United States Army Corps of Engineers (USACOE) prepared a report focused on drainage, flood control, and navigation needs of the Caloosahatchee River Basin, and one recommendation was construction of the S-79 structure. The key objectives of the S-79 structure were to eliminate undesirable salinity in the lower Caloosahatchee River, prevent the rapid depletion of water supplies, and raise the prevailing dry weather water table levels. The S-79 structure was constructed in 1965. It is a lock and dam structure that is also known as the Franklin Lock and Dam. The S-79 structure captures all upstream fresh water discharges that go into the CRE. The S-79 structure demarcates the head of the CRE, which extends 26 miles downstream to Shell Point, where it empties into San Carlos Bay in the southern portion of the greater Lower Charlotte Harbor Estuary. Most of this surface water flow takes a southerly route, flowing to the Gulf of Mexico under the Sanibel Causeway that crosses San Carlos Bay. When fresh water inflows are high, tidal action pushes some of this water back up into Matlacha Pass and Pine Island Sound. Additionally, some water exits to the south and flows into Estero Bay through Matanzas Pass. Salinity exhibits a strong gradient in the CRE. Changes in the watershed upstream of the S-79 structure have profoundly influenced the delivery of fresh water to the CRE. Runoff is now more variable with higher wet season flows and lower dry season discharges. Large volumes of fresh water during the wet season can flush salt water from the tidally-influenced sections of the water body, resulting in low salinity conditions throughout most of the CRE. In contrast, fresh water inflow at the S-79 structure can stop entirely during the dry season, especially during significant drought events. This results in saline intrusion that can extend upstream to the S-79 structure. Fluctuations of this magnitude at the head and mouth of the system cause mortality of organisms at both ends of the salinity gradient. Downstream of the S-79 structure, the CRE was significantly altered by multiple dredging activities, including the removal of extensive shoals and oyster bars. Seven automobile bridges, a railroad trestle, and the Sanibel Causeway were built between the 1880s and 1960s. A large canal network was built along the northern shoreline of the CRE in Cape Coral. To provide navigational access from the canal network to deeper water, multiple access channels were dredged within the CRE. Alterations to the delivery of fresh water combined with structural changes to the tidally-influenced sections of the water body have had lasting ecological consequences. These include the loss of extensive shoals and oyster bars, loss of a flourishing bay scallop fishery, and significant decline in seagrass cover in deeper areas. MFLs An MFL is the limit at which further withdrawals would be significantly harmful to the water resources or ecology of the area. The District's rules define significant harm as the "temporary loss of water resource functions, which results from a change in surface or ground water hydrology, that takes more than two years to recover, but which is considered less severe than serious harm." Fla. Admin. Code R. 40E-8.021(31). The rule further specifies that a water body's specific water resource functions addressed by an MFL are defined in the MFL technical support document. Id. MFLs are calculated using the best information available. The regulatory agency is required to consider changes and structural alterations to watersheds, and the constraints such changes or alterations placed on the hydrology of an affected watershed. Certain waterbodies may not serve their historical hydrologic functions and recovery of these waterbodies to historical hydrologic conditions may not be economically or technically feasible. Accordingly, the regulatory agencies may determine that setting an MFL for such a water body based on its historical condition is not appropriate. Caloosahatchee MFL For the CRE, MFL criteria were designed to protect the estuary from significant harm due to insufficient fresh water inflows and were not guidelines for restoration of estuarine functions to conditions that existed in the past. The MFL criteria consider three aspects of the flow in terms of potential significant harm to the estuary: (1) the magnitude of the flow or the volume of fresh water entering the estuary; (2) the duration of time that flows can be below the recommended level before causing significant harm; and (3) the return frequency, or the number of times the MFL can be violated over a number of years before it results in significant harm, recognizing that natural climatic variability will be expected to cause fresh water inflows to fall below recommended levels at some natural frequency. The CRE MFL initially adopted in 2001 was primarily based on the salinity tolerance of one valued ecosystem component (VEC). The VEC was Vallisneria americana or tape grass, a fresh water aquatic plant that tolerates low levels of salinity. A major assumption of this approach was that flow and salinity conditions that protect Vallisneria would also protect other key organisms in the estuary. The 2001 CRE MFL was based on a regression model for estimating the relationship between surface salinity measured at the Ft. Myers monitoring station located in the Ft. Myers Yacht Basin and discharge at the S-79 structure. Although the District monitors surface and bottom salinity at multiple stations in the CRE, the Ft. Myers monitoring station is located centrally in the CRE and at the historical downstream extent of the Vallisneria habitat. The Ft. Myers monitoring station also has the most comprehensive period of record of monitoring data available. The fixed data sondes that monitor surface and bottom salinity are located at 20 percent and 80 percent of total river depth measured at mean low water. The data sondes continuously measure temperature and specific conductivity and, depending on the manufacturer, contains programs that calculate salinity. Those calculations are based on standards recognized and used worldwide by estuarine, marine, and oceanographic scientists.1/ The regression model only implicitly included inflows from the Tidal Caloosahatchee Basin sub-watershed downstream of the S-79 structure. To address this, during the 2003 re-evaluation, a linear reservoir model of Tidal Caloosahatchee Basin inflows was developed. The regression model results showed that a total inflow from S-79 plus the Tidal Caloosahatchee Basin of about 500 cubic feet per second (cfs) was required to produce a salinity of 10 at the Ft. Myers monitoring station. Thus, the 2001 CRE MFL of 300 cfs measured at the S-79 structure would produce a salinity of 10 at the Ft. Myers monitoring station only with additional inflow from the downstream Tidal Caloosahatchee Basin sub- watershed. However, that additional inflow estimate was highly uncertain. The conclusion was that actual flow measurements over a period of time were needed in order to perform more robust calibrations for the new models that were being developed. The Re-evaluation The District's re-evaluation effort began in 2010 after the Conservancy of Southwest Florida filed a petition requesting review of the Caloosahatchee MFL. At the time, the governing board denied the petition but directed staff to undertake additional research and monitoring to ensure a future revision would be supported by the best information available. The first step was to review the September 2000 Final Peer Review Report (PRR) for the initial adoption. The 2000 PRR identified several items the District should consider, including a hydrodynamic salinity model, a numerical population model for Vallisneria, quantification of habitat value for Vallisneria, and documentation of the effects of minimum flows on downstream estuarine biota. The 2000 PRR documented concerns that the current MFL was based solely on the salinity tolerance of Vallisneria and recommended using multiple indicator species. To address those recommendations, the District conducted studies to evaluate multiple ecological indicators, such as zooplankton, aquatic vegetation, oysters, benthic communities, and blue crabs, in the Caloosahatchee from the S-79 structure to beyond Shell Point. In addition, the District collected flow data from the Tidal Caloosahatchee Basin sub-watershed for at least five years to develop watershed, flow, and hydrodynamic models that could properly simulate inflows and salinity responses. When the initial research was complete in 2016, the District published the Draft Science Document containing 11 component studies. In September 2016, the District held a two- day Science Symposium to present the 11 component studies and gather public comment. In response to public comment, the District performed additional evaluations, modeling, and updated the component studies to produce a Draft Technical Document. A Peer Review Panel reviewed the Draft Technical Document, which included the Draft Science Document. The Peer Review Panel has over 150 years of combined relevant scientific experience. The Peer Review Panel toured the CRE by air and water. The District also held a Peer Review Session to engage the public and obtain feedback. The Peer Review Panel's 2017 report (PRP report) stated that the District had "crafted a well-executed and well- documented set of field and laboratory studies and modeling effort" to re-evaluate the CRE MFL. The PRP report supported the 11 component studies, the modeling, the evaluations, and the initial proposed rule language. The Final Technical Document published in January 2018 incorporated five different models and additional science, examining the entire watershed and the criteria itself. The Final Science Document was Appendix A to the Final Technical Document and contained the scientific research and analysis that was done for the 11 component studies, the modeling, and the additional scientific analyses performed in response to public and stakeholder input. The District initiated rule development in December 2017. Rule development workshops were held in February and June 2018 and a stakeholder technical meeting was held in May 2018. The District validated the comments after each workshop and meeting, and revised the proposed rule language. The District published its Notice of Proposed Rule on July 23, 2018.2/ At its September 13, 2018, meeting, the District's governing board held a public hearing on the Proposed Rule. The mayors of Sanibel, Cape Coral, and the Town publicly commented at the hearing. After considering public comments, the governing board adopted the Proposed Rule. The District documented and responded to each public comment, memorializing the information in the Final Technical Document. Later, after the rule workshops and May 2018 technical meeting, the District prepared and presented all of the updated information, including public comment, at the September 2018 adoption hearing. Thus, the District's re-evaluation process was open and transparent. The Re-evaluated Caloosahatchee MFL The science supporting the re-evaluation involved a comprehensive assessment of the effects of diminished dry season fresh water inflows on the CRE. The dry season was chosen for two reasons. First, because it is well-established that the upstream migration of salt combined with reduced fresh water inflow alters the health and productivity of estuarine habitats. Second, because the dry seasons are the times when the current MFL criteria are likely to be exceeded or violated. The 11 component studies targeted specific concerns regarding physical and ecological characteristics. Together they offered a holistic understanding of the negative effects of diminished fresh water inflow on estuarine ecology. The re-evaluated MFL criteria were developed using a resource-based approach. The approach combined the VEC approach and the habitat overlap concept. The habitat overlap approach is based on the idea that estuaries serve a nursery function and salinity determines the distribution of species within an estuary, including distribution during different life stages. The combined approach studied the minimum flow requirements of the various indicator species in terms of magnitude, duration, and return frequency, resulting in the following three aspects of the flow: (1) for magnitude, a 30-day moving average flow of 400 cfs measured at the S-79 structure; for duration, an MFL exceedance occurs during a 365-day period when the 30-day moving average flow at S-79 is below 400 cfs and the 30-day moving average salinity exceeds 10 at the Ft. Myers salinity monitoring station; and (3) for return frequency, an MFL violation occurs when an exceedance occurs more than once in a five-year period. The magnitude component is based on the salinity requirements of Vallisneria, along with results from the 11 studies modeling salinity and considering the salinity requirements of the other VECs. The duration component is based mainly on the estimates of rate of loss of Vallisneria shoots when salinity rises above 10 and the recovery rate of the shoots when salinities fall back below 10. Return frequency was determined based on long-term rainfall records rather than flow measurements from the S-79 structure, which the PRP report felt was well justified. In addition to the component studies, the re-evaluated MFL criteria and existing recovery strategy were evaluated using a suite of hydrologic and ecological models simulating long-term fresh water inflow to the CRE associated with varying management options, the resulting salinity in the CRE, and the ecological response of indicator species that are sensitive to low fresh water inflows. Five models were utilized. Three models simulated fresh water inflows to the CRE: two for S-79 flows; and one for Tidal Caloosahatchee Basin sub-watershed flows. The other two models were a three-dimensional hydrodynamic salinity model and a Vallisneria model. Tidal Caloosahatchee Basin sub-watershed has a number of tributaries that drain fresh water into the CRE. The flow at several of the tributaries was monitored for a five-year period. The measured flow was used to calibrate a watershed model and conduct a long-term simulation. The results showed an average fresh water inflow for all seasons of approximately 430 cfs. The average fresh water inflow during the dry season was 245 cfs while the wet season average fresh water inflow was 613 cfs. Fresh water inflow from the Tidal Caloosahatchee Basin sub- watershed was approximately 20 percent of total fresh water inflow to the CRE while 80 percent was released through the S-79 structure. Petitioners' and Intervenors' Objections 400 cfs Is Too Low Sanibel relied on a memorandum prepared by Dr. David Tomasko (Tomasko report) concerning his company's review of the January 2018 Final Technical Document supporting the Proposed Rule. The Tomasko report, dated October 23, 2018, was in the form of a "technical memorandum" outlining "preliminary findings." The Tomasko report was admitted as a joint exhibit; however, Dr. Tomasko did not testify at the final hearing. The Tomasko report is hearsay that was not used to supplement or explain competent direct evidence. Although hearsay is admissible in this proceeding, it cannot be the sole basis for a finding of fact.3/ See § 120.57(1)(c), Fla. Stat. The District's expert witnesses, who testified at the final hearing, explained that ten of the 11 component studies identified average indicator flows at S-79 ranging from 237 to 545 cfs with standard deviations ranging from plus or minus 57 to plus or minus 774 cfs.4/ The District's experts performed three different evaluations of those flow results. They identified the mean of all the means, calculated the median of the means, and performed a probability density function. The flow results for each of the three evaluations were 381 cfs, 400 cfs, and 365 cfs, with standard deviations that ranged from plus or minus 277 cfs to plus or minus 706 cfs. The District's experts testified that the three flow results are indistinguishable from a statistical point of view. The District chose 400 cfs because it was the highest flow result, and, therefore, the most protective of the three. The Petitioners and Intervenors failed to present evidence that showed any deficiencies in the District's component studies, hydrologic, hydrodynamic, or statistical modeling, or analysis of compliance data. The preponderance of the evidence established that the District used the best available science to calculate the MFL criteria. The District did not act arbitrarily or capriciously when it chose 400 cfs as the magnitude component of the MFL criteria. Inclusion of Salinity in the MFL Criteria The preponderance of the evidence also established that Vallisneria continues to be a particularly useful indicator of environmental conditions in the CRE. It supports essential ecological goods and services, is sensitive to salinity fluctuations at the ecosystem scale, and has value to a variety of stakeholders. The location of Vallisneria habitat in the upper CRE and its negative response to increased salinity made it an excellent candidate as an ecological indicator for fresh water inflow. A combination of field monitoring, mesocosm studies, and modeling results allowed the application of Vallisneria responses as a platform to quantify the effects of high salinity duration in the upper CRE. Component Study Eight reviewed the development and initial application of a simulation model for Vallisneria in the CRE. The Vallisneria model was used to evaluate the salinity conditions that led to net annual mortality, or, in other words, the duration of high salinity exposure that led to decreased Vallisneria shoots versus the duration of low salinity conditions required for recovery. Component Study Seven included an analysis of the relationship between the number of consecutive days where salinity at the Ft. Myers monitoring station was greater than 10 and the percentage of initial Vallisneria shoots remaining at the end of each high salinity period. To further evaluate the duration element associated with the MFL criteria, the field monitoring data contained in Component Study Seven was evaluated with the mesocosm and modeling results. All three sources were analyzed similarly to derive a combined curve showing high salinity exposure duration that is significantly harmful to Vallisneria. The model also provided information that was used to quantify the duration of low salinity conditions required for Vallisneria to recover a relative fraction of shoots after high salinity exposure. Merging the exposure and recovery evaluations facilitated a determination of the unfavorable salinity duration that could significantly harm Vallisneria habitat. With significant harm defined as the environmental harm from which two years are required to recover, the determination was that Vallisneria should experience no more than 55 consecutive days of salinity greater than 10. However, stakeholders expressed concerns regarding the percentage loss of Vallisneria habitat after 55 days of high salinity exposure. In response, the District conducted further analysis of modeling results and revised the duration component to accept the stakeholder recommendation, now expressed in the Proposed Rule, of a 30-day moving average salinity greater than 10. The Petitioners and Intervenors argued that by expressing the MFL as a "flow plus salinity component" the Proposed Rule enlarges, modifies, or contravenes the specific provisions of law implemented. However, the duration component is part of compliance and represents the duration of time that flows can be below the recommended level before causing significant harm to the indicator species Vallisneria. The MFL in the Proposed Rule is a 30-day moving average flow of 400 cfs measured at the S-79 structure. Flow is both measured and operationally controlled at the S-79 structure. However, as previously found, there are other sources of fresh water entering the CRE downstream of the S-79 structure. The District does not control and cannot control these downstream sources, which modeling reveals contribute approximately 20 percent of total fresh water inflow to the CRE. By including salinity, the District can account for fresh water inflows coming from the tidal basin when there are low or no flows at S-79 since the significant harm threshold in the CRE is directly related to salinity tolerance of the indicator species Vallisneria. The District's experts also testified that salinity can be used as a flow component because it is not affected by chemical or biological processes and is an indicator of how much fresh water is entering the system.5/ Salinity is included in the duration component of the MFL criteria and is an exceedance criterion because the science established that the salinity gradient is crucial to the overall health of the CRE. Including salinity in the duration component of the MFL criteria achieves the purpose of the statutory mandate to set MFLs that are designed to avoid significant harm to the water resources and ecology of the area. No Unit of Measurement for Salinity The Petitioners and Intervenors argued that the Proposed Rule is vague because the language does not contain any units for salinity. The UNESCO calculation is the standard equation used by the estuarine and marine science community to convert specific conductivity and temperature data to salinity. The District's experts testified that the UNESCO calculation reports salinity as a ratio, which is a dimensionless number and has no units. The District uses the UNESCO calculation and performs the conversion in a spreadsheet that it maintains. In some instances, certain brands of data sondes are programmed to perform the calculation and provide the salinity number. The preponderance of the evidence established that use of the practical salinity unit (PSU) is not technically correct. PSU is a misnomer, a pseudo-unit equivalent to a unitless salinity number. The Petitioners' and Intervenors' expert witness, Dr. Anthony Janicki, conceded there is no difference between reporting salinity as unitless or as PSU. And although technically incorrect, he suggested that placing the word "practical" or putting "PSU" in the Proposed Rule would reduce confusion and vagueness. However, since the preponderance of the evidence established that use of PSU is not technically correct, the use of a pseudo-unit would actually cause confusion instead of reduce confusion. The Petitioners and Intervenors also argued that the Proposed Rule is vague because the language does not state that the method of measuring salinity is specific conductivity, or that the equation used to convert specific conductivity and temperature data to salinity is the standard developed by UNESCO. The Petitioners and Intervenors essentially argued that members of the public and those who may be regulated by the Proposed Rule are left to guess about the method or methods used to measure salinity. Because the Proposed Rule identifies and locates by latitude and longitude coordinates the Ft. Myers salinity monitoring station as the location where salinity would be measured for compliance, the Proposed Rule language is not vague. The Proposed Rule is not vague because it does not describe the data sondes, what parameters are measured by the data sondes, and how those parameters are converted to a salinity number. Salinity Monitoring Location and Mean Low Water The Petitioners and Intervenors argued that the Proposed Rule is vague for failing to define the phrase "20% of the total river depth at mean low water," and is arbitrary or capricious for failing to include more than one salinity monitoring station. Total river depth or the water column depth is a standardized measurement that is made from the surface down to the bottom of the river bed. Mean low water is commonly understood in the oceanographic and coastal sciences community as the average of all low tides over the time period defined as the national tidal datum epic. The District's expert witness, Dr. Cassondra Armstrong, testified that mean low water can be determined by using two documents prepared by the National Oceanographic and Atmospheric Administration (NOAA), i.e., the NOAA tide charts and glossary. The District's expert witnesses testified that "20% of the total river depth at mean low water" is the location of the data sonde at the Ft. Myers monitoring station that measures surface salinity. This is also the depth at which Vallisneria is located in the CRE. Since, the Proposed Rule language simply identifies the location of the existing data sonde at the Ft. Myers salinity monitoring station, the language is not vague. The preponderance of the evidence established that the Ft. Myers salinity monitoring station has two salinity data sondes, the one at 20 percent of the total river depth and the other at 80 percent. The data sonde at 20 percent of the total river depth was identified in the Proposed Rule for the following reasons. First, this is the depth where Vallisneria grows and is representative of the salinity exposure for Vallisneria. Second, it guarantees the data sonde is always submerged and able to record data. Third, it has the most comprehensive period of record of monitoring data available. As previously found, Vallisneria continues to be a particularly useful indicator of environmental conditions in the CRE. The location of Vallisneria habitat in the upper CRE and its negative response to increased salinity made it an excellent candidate as an ecological indicator for fresh water inflow. Because the preponderance of the evidence established that Vallisneria continues to be a particularly useful indicator of environmental conditions in the CRE, the choice of the Ft. Myers monitoring station is not arbitrary or capricious. Water Resource Functions vs. Environmental Values The District's MFL rule specifies that a water body's specific water resource functions addressed by an MFL are defined in the MFL technical support document. See Fla. Admin. Code R. 40E-8.021(31). The Final Technical Document identified the relevant water resource functions of the CRE as fish and wildlife habitats, estuarine resources, water supply, recreation, navigation, and flood control. The Petitioners and Intervenors argued that the environmental values listed in Florida Administrative Code Chapter 62-40, also known as the Water Resource Implementation Rule, were not adequately addressed in the Final Technical Document. A proposed rule challenge is not the proper forum to determine whether a proposed rule is consistent with the Water Resource Implementation Rule. Such a determination is within the exclusive jurisdiction of the Department of Environmental Protection under section 373.114(2), Florida Statutes. Consistency of the District's Proposed Rule with the Water Resource Implementation Rule of the Department of Environmental Protection is not a basis in this proceeding for a finding that the Proposed Rule is an invalid exercise of delegated legislative authority. Other Issues The Petitioners and Intervenors raised other issues during the hearing, although not specifically argued in their proposed final order. Since those issues were identified as disputed issues in the Joint Pre-hearing Stipulation, they are addressed below. 1. Elimination of Single-day Exceedance Criterion During the rulemaking process, Sanibel and SCCF sent the District a letter requesting justification for eliminating the single-day exceedance salinity criterion in the current rule. The District staff evaluated the available Caloosahatchee River MFL compliance record, dating back to when the MFL was adopted in September 2001. The District maintains a historical record of MFL monitoring data and reviewed it to determine if the single-day exceedance salinity criterion was exceeded before the 30-day moving average criterion. The compliance record showed five exceedance events of the single-day salinity criterion have occurred. However, the compliance record also showed that the 30- day moving average salinity criterion had already been exceeded before the five events occurred. In other words, the single-day criterion was never exceeded before the 30-day moving average criterion. Based on this evaluation, the District eliminated the single-day exceedance salinity criterion because it did not provide any additional resource protection. The District's decision was not arbitrary or capricious. 2. Not Using the Latest Model Evaluation of recommended MFL criteria and a recovery strategy for the CRE were greatly aided by integration of a suite of hydrologic and ecological models simulating (1) long-term fresh water inflow associated with varying management options, (2) the resulting salinity in the estuary, and (3) ecological response of indicator species that are sensitive to low fresh water inflows. Five models were specifically utilized, including three models for simulations of fresh water inflows to the CRE, a three-dimensional hydrodynamic salinity model, and a Vallisneria model. The three models simulating fresh water inflows included (1) the South Florida Water Management Model (SFWMM) to simulate fresh water discharges at S-79, which includes regional operations of Lake Okeechobee and incorporates Caloosahatchee River irrigation demands; (2) the C-43 Reservoir Model, which uses the SFWMM-simulated daily S-79 flow as input and simulates the management benefit of the C-43 Reservoir; and (3) the Watershed (WaSh) Model to simulate tidal tributary inflow from the Tidal Caloosahatchee Basin sub-watershed. The Caloosahatchee Hydrodynamic/Salinity Model was based on the Curvilinear Hydrodynamic Three-dimensional Model (CH3D) modeling framework with the functionality of simulating the spatial salinity structure across the entire estuary. The Vallisneria Model took the CH3D modeled salinity as input to simulate Vallisneria growth at critical locations in the estuary. The District did review the more recent Environmental Fluid Dynamic Code (EFDC) model developed for the Caloosahatchee Total Maximum Daily Load (TMDL) and being used by the Department of Environmental Protection. The District's expert witness, Dr. Detong Sun, testified that until 2014, the hydrodynamic part of the EFDC model was not working well. He testified that in 2016, the District still had concerns and suggested the use of the District's continuous monitoring data from seven locations across the CRE rather than grab samples for model calibration. Dr. Sun's opinion was that the EFDC model has improved in recent years, but was still behind the CH3D model in terms of performance. The District's expert witness, Dr. Amanda Kahn, testified that the water quality component of the EFDC model was not appropriate for this re-evaluation because the MFL is about water quantity, not water quality. The water quality component of the EFDC model addresses nutrient loadings, not minimum flows. Dr. Kahn also testified that in setting MFL criteria for the CRE, salinity was not a water quality component. Salinity was used as a water quantity component because it does not change with biological processes and can be a measure of how much fresh water is coming into the system. Based on a preponderance of the evidence, the District's decision not to use the EFDC model was not arbitrary or capricious. 3. Seasonality The Petitioners and Intervenors argued that the District is required to set an MFL that varies by season. For the CRE, the District set MFL criteria that protect the system from low flow that would occur in either the wet or dry season. As previously found, the re-evaluation studies focused on the dry season for two reasons: first, because it is well-established that the upstream migration of salt combined with reduced fresh water inflow alters the health and productivity of estuarine habitats; and second, because the dry seasons are the times when the current MFL criteria are likely to be exceeded or violated. The MFL statute states that "when appropriate, [MFLs] may be calculated to reflect seasonal variations." § 373.042(1)(b), Fla. Stat. The preponderance of the evidence showed that for the CRE, it was not necessary to set an MFL that varied by season. Improper Purpose The Petitioners, Sanibel, Cape Coral, and the Town, did not participate in this proceeding primarily to harass or to cause unnecessary delay or for frivolous purpose or to needlessly increase the cost of litigation. The Petitioners did not participate in this proceeding for an improper purpose. The Intervenors, Fort Myers, Estero, Bonita Springs, and CCP, did not participate in this proceeding primarily to harass or to cause unnecessary delay or for frivolous purpose or to needlessly increase the cost of litigation. The Intervenors did not participate in this proceeding for an improper purpose.
Findings Of Fact Upon a consideration of the oral and documentary evidence adduced at the hearing in this cause, the following pertinent facts are found: 1/ By application number 25793, the applicant seeks a permit to construct and operate a proposed surface water management system to serve a 2,541 acre project within the St. Johns River Basin in Indian River County. The proposed system will consist of a perimeter dike, a central canal with interior laterals and four discharge pumps. The applicant will be discharging into the St. Johns Marsh and seeks a discharge capacity of 139,000 GPM. Three of the discharge pumps are to be located at the southeast corner of the property and a two-way 25,000 GPM pump is to be located at the intersection of the central canal and the western boundary of the property. By application number 25794, the applicant seeks a permit for the use of surface and artesian water for the irrigation of the same 2,541 acres of pasture and truck crops. The applicant requests to withdraw surface water from the St. Johns Marsh by means of a two-way 25,000 GPM pump located at the intersection of the central canal and the western property boundary and to withdraw water from the Floridan aquifer by means of eight eight-inch artesian wells. The amount requested is 5,294 acre-feet per year with a maximum monthly pumpage of 1.47 billion gallons. A staff report of the Central and Southern Florida Flood Control District (FCD) concluded that the major problem with the permit applications is the impact on water quality of the receiving bodies of water and that nutrients and other pollutants will be introduced into runoff waters discharged into the St. Johns Marsh, which is the source of the public water supply for South Brevard County. The staff therefore recommended that the applicant institute a water quality and quantity monitoring program to monitor discharges to the Marsh. The staff further recommended that the applicant not be allowed to discharge from the western property boundary nor irrigate from the ditch on the western property boundary. It was recommended that the two-way 25,000 GPM pump be installed adjacent to the other pumps located at the southeast corner of the property. More specifically, the staff found that if a permit were to be issued pursuant to application number 25793, it should be subject to the conditions that: the allowable discharge capacity to be 104,000 GPM, with discharges to be east to the St. Johns Marsh by means of one 44,000 GPM pump, one 35,000 GPM pump and one 25,000 PM two-way pump to be located at the southeast corner of the property; the applicant notify the FCD prior to any excavation of materials from land lying east of the east property boundary and, if such excavation is done, a discontinuous borrow ditch be created by either leaving 25 foot portions of undisturbed marsh or by placing 25 foot earthen plugs at approximately 500 foot intervals (this was later modified at the hearing to 1,000 foot intervals); and the applicant submit monthly reports of total daily discharges and water quality, the samples to be taken at the southeast corner of the property. With regard to application number 25794, the staff recommended that if such permit were to be issued, it be subject to the following conditions: for the use of surface water, an annual allocation of 2329.3 acre- feet per year and for the use of artesian water, an annual allocation of 2518.5 acre-feet per year, with a maximum monthly pumpage from all sources of 355.3 million gallons; no withdrawal of surface water from the St. Johns Marsh when the water level in Blue Cypress Lake drops to 22.0' msl.; surface water to be withdrawn by means of a 25,000 GPM two-way pump located at the property's southeast corner; artesian waters to be withdrawn by eight eight-inch wells with effective and operative controls placed thereon and analyses of water samples from the water discharge of each the submission of monthly reports of total monthly pumpages and total monthly flows; and permit for the withdrawal of surface and artesian water to expire on January 15, 1979. At the hearing, the applicant agreed to the recommended conditions placed upon the permits by the staff report with the exception of: the amount of the allowable discharge (staff recommending 104,000 GPM as opposed to a desired 139,000 GPM); the location of the 25,000 GPM two-way pump (staff recommending southeast corner as opposed to a proposed site on the western boundary of the property); the expiration date of January 15, 1979. The Environmental Protection Bureau of the Florida Game and Fresh Water Commission requested the FCD to delay issuance of permits for all projects in the Upper St. Johns River basin until a comprehensive water management plan for the area is formulated. Read into the record was a resolution adopted by the Commission on May 16, 1975, recommending that "the further destruction of the marsh be curtailed and a plan be formulated for the return of the diverted waters as a management tool for restoration of fish and wildlife resources." On behalf of the Florida Audubon Society, Mr. Charles Lee contended that, because of this resolution and request of the Game and Fresh Water Fish Commission and that agency's constitutional status, the FCD is precluded from issuing the subject permits. Intervenors and members of the general public who were opposed to the issuance of the instant permits expressed the following concerns: the low water quality and quantity of the St. Johns River and its marshes; the decline in hunting and fishing because of agricultural activities in the St. Johns River valley; the loss of marsh land due to agricultural activity; the lack of a basic water management program for the area; the lack of remedial measures should degradation of the water occur; and the lack of an expiration date for the surface water management system permit.
Recommendation Based upon the findings of fact and conclusions of law recited above, it is the recommendation of the hearing officer that application numbers 25793 and 25794 be granted, subject to those special conditions set forth in the Staff Report as modified by the following: In paragraph number 3 on page 14 of the Staff Report, substitute the words "1,000 foot intervals" for "500 foot intervals;" Add as paragraphs 6 on page 15, paragraph 6 on page 16 and paragraph 7 on page 18 the following: "Should the data in the monthly reports submitted by the applicant indicate the occurrence of a degradation of the waters utilized, the applicant will be required to remedy the situation causing the de- gradation." Add as paragraph 7 on page 15 the following: "7. This permit shall expire on January 15, 1979." Respectfully submitted and entered this 25th of March, 1976, in Tallahassee, Florida. DIANE D.

The Issue Whether the applicants own the property in question? Whether the project would comply with the criteria of the South Florida Water Management District contained in Basis of Review for Surface Water Management Systems, specifically Sections 3.1.3 and 3.2? Whether flood protection would be inadequate or septic tanks unsuitable or whether the public health and safety would be compromised or the ultimate purchasers be deprived of usage of the property due to inundation in violation of Chapter 373, Florida Statutes (1981), or Rule 40E-4.301(1), Florida Administrative Code?
Findings Of Fact Ms. Williamson and Messrs. Leggett and Collins hold in fee simple a triangular 117.24-acre parcel in Okeechobee County as tenants in common under a warranty deed executed in their favor by one W. C. Sherman. They propose to develop the property as a trailer park (complete with airstrip) large enough to accommodate 109 trailers. To this end, soil would be dug up from the center of the property and used to raise the elevation of the surrounding land above the 100-year floodplain. (T. 47) The applicants have a dredging permit from the Department of Environmental Regulation authorizing them to excavate 629,889 cubic yards. They are proposing to dig to a depth of 76 feet below ground. This would create an 18-acre body of water ("Poe's Lake") which would overflow a V-notched weir into a county canal. The county canal would take the water to C- 38, one of the large canals to which the Kissimmee River has been relegated, at a point about 18 miles upstream from Lake Okeechobee. Runoff would wash over residential lots and roadways; the site would be graded to assure drainage into Poe's Lake. The minimum road crest elevation would be 30 feet NGVD ("[a]round twenty-nine feet" T.52), as compared to the control elevation for surface waters of 28.5 feet NGVD. WATER QUALITY The developers plan septic tanks for wastewater treatment. At the close of all the evidence, counsel for the applicants stated that sanitary sewers could be installed instead. Respondents' Proposed Recommended Order, p. With all the housing units in use, at least 10,900 gallons of effluent would seep into the ground from the tanks daily. There would be some evapotranspiration, but all the chemicals dissolved in the effluent would eventually end up in the groundwater. During the dry season, septic tank effluent would cause mounding of the groundwater and some groundwater movement toward, and eventual seepage into, Poe's Lake. The eventual result would be eutrophication and the growth of algae or macrophytes on the surface of Poe's Lake. This would cause dissolved oxygen violations in Poe's Lake. Discharges from the lake would inevitably occur, aggravating the situation in C-38, which already experiences dissolved oxygen levels below 5.0 milligrams per liter in the rainy summer months. Some fraction of the nutrients in the effluent from the septic tanks would ultimately reach Lake Okeechobee itself. The sheer depth of the excavation would create another water quality problem. Under the anaerobic conditions that would obtain at the bottom of Poe's Lake, bacteria acting on naturally occurring sulfates would produce hydrogen sulfide, ammonia and various other reduced organic nitrogen compounds. These substances are toxic to human beings and would, in some indeterminate quantity, enter the groundwater from Poe's Lake. This would affect the taste and perhaps the potability of water from any well nearby. It would be "possible to design a better system where there would be nutrient removal and a greatly reduced probability of violation of the dissolved oxygen criterion and obviation of the potential for ground water contamination." (T. 200) Installation of a baffle on the weir would serve to prevent buoyant debris from entering surface waters of the state. BASIS OF REVIEW Official recognition was taken of the "Basis of Review for Surface Water Management Permit Applications Within the South Florid Water Management District," parts of which all parties agree pertain in the present proceedings. Among the criteria stated in this document are: 3.1.3 Waste and Wastewater Service - Potable water and wastewater facilities must be identified. The Applicant for a Surface Water Management Permit must provide information on how these services are to be provided. If wastewater disposal is accomplished on-site, additional information will normally be requested regarding separation of waste and storm systems. 3.2.1.4 Flood protection - Building floors shall be above the 100 year flood elevations, as determined from the most appropriate information, including Federal Flood Insurance Rate Maps. Both tidal flooding and the 100 year, 3 day storm event shall be considered in determining elevations. b. Commercial and industrial projects to be subdivided for sale are required to have installed by the permittee, as a minimum, the required water quality system for one inch of runoff detention or one half inch of runoff retention from the total developed site. State standards - Projects shall be designed so that discharges will meet State water quality standards, as set forth in Chapter 17-3, Retention/detention criteria - Retention and/or detention in the overall system, including swales, lakes, canals, greenways, etc., shall be provided for one of the three following criteria or equivalent combinations thereof . . . Wet detention volume shall be provided for the first inch of runoff from the developed project, or the total runoff from a 3-year, 1-hour rainfall event, 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. 3.2.4.1 Discharge structures should include gratings for safety and maintenance purposes. The use of trash collection screens is desirable. Discharge structures shall include a "baffle" system to encourage discharge from the center of the water column rather than the top or bottom. 3.2.4.4.2 b. Control elevations should be no higher than 2 feet below the minimum road centerline elevation in the area served by the control device in order to protect the road subgrade. Simply detaining runoff before discharging it offsite will not insure that the water quality standards set forth in Chapter 17-3 will be met. Whether the standards are met depends on, among other things, the composition of the runoff. FWF'S INTEREST Among the purposes of the FWF, as stated in its charter, Shall be to further advance the cause of conservation in environmental protection, to perpetuate and conserve fish and wildlife, oil, water, clean air, other resources of the State and so manage the use of all natural resources, that this generation and posterity will receive the maximum benefit from the same. (T. 248-9) Four or five thousand Floridians belong to FWF. FWF members "make use" (T. 250) of the waters of Lake Okeechobee, the Kissimmee River and specifically of the waters in C-38. PROPOSED FINDINGS CONSIDERED The applicants and FWF filed post hearing memoranda and proposed recommended orders including proposed findings of fact which have been considered in preparation of the foregoing findings of fact. They have been adopted, in substance, for the most part. To the extent they have been rejected, they have been deemed unsupported by the weight of the evidence, immaterial, cumulative or subordinate.
Recommendation Upon consideration of the foregoing, it is RECOMMENDED: That SFWMD deny the pending application for surface water management permit.

Findings Of Fact By application filed on September 9, 1980, Respondent/Applicant, John H. Land Builders, Inc., sought a permit from Respondent, Department of Environmental Regulation (DER), to conduct dredge and fill activities in an approximate one acre area located in the southeast corner of a proposed housing development in Section 10, Township 29 South, Range 19 East, in Hillsborough County, Florida. A copy of this permit application may be found as DER Composite Exhibit B. Specifically, Land sought to excavate 4,100 cubic yards of material (muck) and to backfill the area with 14,400 cubic yards of granular material from adjacent uplands to allow for development of a street and building lots in an unnamed wetland. A permit from DER is required because the project involves a wetland that is contiguous with a ditch that connects to the Palm River, all of which constitute waters of the State that are subject to dredge and fill permitting requirements. The plans have been reviewed by other state and local authorities in the Hillsborough County area, and no adverse comments have been received. After the installation is completed, the elevation of the land will be raised, and will permit five homesites to be built on the land as well as the construction of an access road to the property from an adjacent street. The installation in question is but a small part of a larger proposed housing development known as Timberlake Subdivision that will ultimately involve more than 300 homesites. However, no further dredge and fill activities under DER jurisdiction will be undertaken. The proposal of Respondent/Applicant was received by the Department and certain timely additional requests were made from the Department to the Applicant to provide information necessary to evaluate the request for permit. Applicant subsequently furnished the required information, and it may be found in DER Exhibit C. The Department performed a field inspection and review of the dredge and fill site, including the surrounding areas, to assess the impact of water quality caused by proposed dredging and filling activities in wetlands areas. It concluded that the Applicant had affirmatively provided reasonable assurance to the Department that the short-term and long-term effects of the activity would not result in violations of the water quality criteria, standards, requirements and provisions of Chapter 17-3, Florida Administrative Code. A copy of the permit application appraisal may be found in DER Exhibit A. On January 21, 1981, DER issued its Intent to Issue a dredge and fill/water quality certification with certain conditions therein, including the requirement that future development be dependent upon separate stormwater review by the Department (DER Exhibit D). On October 20, 1980, Applicant filed a Notice of Stormwater Discharge with the Department's Southwest District Office in Tampa (DER Composite Exhibits B & F). Thereafter, the Department conducted a field inspection and review of the proposed housing development and surrounding areas to determine whether the proposed stormwater discharge would have a significant impact on water quality. Based upon the results of that inspection, which concluded that the proposed discharge would not have a significant impact on the waters of this State, the Department issued Applicant a stormwater exemption on November 7, 1980. The project site is located in an unnamed wetlands area. It is weedy and has a dense cover of primrose willow (Ludwigia peruviana), willow (Salix caroliniana), cattail (Typha sp.), red maple (Ace rubrum) and is overgrown with grapes vines (Vitus rotendifolia). It lies just to the north of a series of fish farms owned by Petitioner, Penisular Fisheries, Inc. Other commercial industries and single family dwellings are found south of the proposed activities. To the west and northwest lie marshlands, two old borrow pits, and Interstate Highway 4. Water runoff from the dredge and fill area will flow to the storm drainage system in the proposed street, and from there to a designated retention pond. Because there will be minor contaminants in the runoff, the water will be retained for treatment for a period of five days, which exceeds the 100 hour retention period required by DER. After treatment, the runoff will flow into a well-defined county drainage ditch west of 58th Street, travel down the ditch which lies adjacent to the fish ponds, and then meander into the existing marshland. Water runoff from the remainder of the project (excluding the dredge and fill area) will drain into the two existing borrow pit lakes which lie close to Interstate Highway 4. The designated retention pond will be located west of the project and has a controlled spill-off elevation. It will provide sufficient treatment to and cleaning of the water to insure that no violation of water quality standards will occur. A stormwater system to be constructed by Applicant will actually reduce the volume of water runoff now occurring. Reasonable assurances have been given that the short-term and long-term effects of the proposed activity will not result in violations of the water quality criteria, standards, requirements and provisions of the Florida Administrative Code. Based upon Use location of the point of discharge of Land's proposed stormwater discharge, the volume and frequency of discharge for which the proposed facilities are designed, and the anticipated constituents of discharge, the proposal will not have a significant impact on the water quality of the waters of this State. Accordingly, the exemption from stormwater licensing requirements was properly issued by the Department. Water quality violations which were alleged to have existed in a ditch on property adjoining the properties of Land and Petitioners were the subject of a notice of violation issued to the owners of that property. However, no notice of violation was ever issued to Land. Further, the ditch is not a part of the installation proposed by Applicant for issuance of the dredge and fill permit. Petitioners' concern is that Applicant has not given reasonable assurance that water quality standards would not be violated by the stormwater discharge and that downstream waters might be contaminated by urban runoff from the project. In reaching that conclusion, Petitioners' expert relied on a review of certain materials submitted to him by Petitioner's counsel. He did not visit the project site, nor had he reviewed drainage plans or construction drawings for drainage improvements contemplated by the notice of stormwater discharge filed by Land.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that Respondent Department of Environmental Regulation grant the requested dredge and fill permit/water quality certification to Respondent/Applicant John H. Land Builders, Inc. It is further RECOMMENDED that the Respondent Department of Environmental Regulation enter a final order confirming the stormwater exemption issued by the Department to Respondent/Applicant on November 7, 1980. DONE and ENTERED this 27th day of April, 1981, in Tallahassee, Florida. DONALD R. ALEXANDER Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 27th day of April, 1981.
Findings Of Fact The Respondent Harper Brothers, Inc., operates a farming and limestone mining operation in Lee County, Florida. It has filed a surface water management permit application for a project to be operated as an adjunct to the mining operation at Green Meadows Mine owned by Harper Brothers. The Respondent Harper Brothers retained consultants in the general fields of engineering, hydrology, surface water management and hydraulics to assist in the formulation of a surface water management plan for the development and operation of their mining site. As a culmination of this effort, Respondent Harper Brothers filed its application for a surface water management system, and permit therefor, with the district. The SFWMD (District), upon receiving applications for surface water management systems and related permits evaluates water quantity, quality and various environmental concerns related to water resources mandated by Chapter 373, Florida Statutes, Chapter 40E, Florida Administrative Code and Chapter 17-3, Florida Administrative Code. Such an application must meet district criteria contained in the statutes and rules in order for the surface water management permit to be issued. The district's staff makes a recommendation to its governing board for approval or denial of such permits, and often with related conditions attached. In the instant case, after review of the various water quality and environmental criteria, the recommendation of the governing board of the agency was for approval of the permit with certain conditions. THE PROJECT The project which is the subject matter of this proceeding is a rock mining operation for the mining of limestone in Lee County, Florida. The application is for the construction and operation of a surface water management system to serve a 405-acre mining operation which, in essence, involves the management of the water produced by "de-watering," or pumping-out of the active rock pit, through use of a retention area, dykes, pumps, culverts and a weir structure; with a view toward keeping the water pumped from the pit (dewatering water), and stormwaters which fall on the site, contained in a retention area which has been designed to retain all the dewatering discharge. The only water discharge envisioned off the site represents the volume of stormwater which falls thereon. The stormwater which would be discharged off the site is that water which actually falls as rain onto the retention area as well as stormwater that is pumped into the retention area from the pit through the use of the two existing dewatering pumps. During excavation of the rock pit, water is discharged from the pit into the on-site retention area through use of these two pumps. An existing weir structure allows some water from the retention area to flow through a ditch to a small lake on the Respondent Harper Brothers' property. Water from the lake is used at the rock mine and some existing farmland of Harper Brothers is supplied irrigation water from it. At present, some farmland is supplied irrigation water through a pump from the retention area and some receives irrigation from the mine pit itself through another pump. The remaining water discharged from the mine pit is held in the retention area where it infiltrates into the ground. The retention area will be surrounded by 3.5-foot high by 12-foot wide dykes. Along the south side of the retention area a double dyke system is proposed. The outer dyke will also be utilized as a road and varies from three to four feet in height with a top width of 36 feet, which will be paved. Stormwater discharged from the retention area would flow through an outfall structure located at a crest elevation of 26.75 feet, National Geodetic Vertical Datum (NGVD). The controlled elevation in the retention area is 26.3 feet NGVD which is maintained by a 3.83-foot wide "bleeder notch." Discharge from this structure would then be routed westward between double dykes under the Harper Brothers' "north-south road" down a swale on the north side of its entrance road to "no-name" slough, the ultimate "receiving waters." It was established by expert witness Missimer, for Respondent Harper Brothers, that the dewatering discharge which would be held in the retention area will infiltrate into the ground at a rate of approximately 43,000 gallons per day per acre per a one-foot elevation in water level. The rate of infiltration in the ground is directly proportional to the "head" increase so that for a two-foot water level with the resulting increased pressure or "head," the infiltration rate would be 86,000 gallons per day per acre. Based on the presently permitted maximum monthly withdrawal rate, at a point of equilibrium would be reached at a water depth in the retention area of 1.3 feet, whereby the rate of water pumped into the retention area equals the rate of infiltration into the ground without considering additionally any evaporation into the atmosphere. Thus, the bleeder notch would be set at the above elevation so that all dewatering discharges from the mine (which may contain rock and other sediments) are effectively retained on site. PRE-DEVELOPMENT VS. POST-DEVELOPMENT DISCHARGES The SF design criteria contained in Chapter 40E, Florida Administrative Code, the applicability of which is not in dispute in this proceeding, provides that the volume of stormwater discharged from such a project cannot exceed the volume of such discharges from the same surface area in its pre-development condition. The development referred to in this instance is, of course, the development of the mine and the related retention area and other water management installations or "improvements." Expert witnesses Glaubitz and Serra testifying for the Respondent Harper Brothers and SFWMD established that the quantity of pre-development discharge from the subject site or surface area, was calculated based upon a "design storm event." This means that the pre-development discharge from the Harper Brothers' mine site was calculated, based upon reviews of the watershed boundary, the slope, the vegetation types, and the hydrologic length of the watershed in the geographical area, as well as through the use of aerial photography and U.S. Geological Survey maps, to show the amounts of surface and stormwaters discharged from this site, or its pre-development surface area, during a 25-year, 3-day duration storm event, meaning a storm lasting for a duration of three days of rain of a severity that has been experienced, according to meteorological records, an average of once in 25 years in the subject geographical area. Based upon these calculations of pre-development discharge rate or volume during a 25-year, 3-day storm event, the pre- development discharge from the Harper Brothers' mine site was calculated to be a volume of 10 cubic feet of water per second (cfs). "Post-development discharge" is the rate of discharge taking into account the same 25-year, 3-day storm event, which is allowed to discharge off the project site after development is completed. The calculation of post- development discharge was computed by taking into account such factors as soil storage capability, stage discharge and calculation of the amount of retention or detention of storm water required on the site. Thus, the calculated post- development discharge of stormwater from the site as it is proposed to be designed, is nine cubic feet per second during such a 25-year, 3-day severe storm, which capability is designed into the proposed project. Thus, the post- development discharge of stormwater off the project site does not exceed, and in fact is less than, the pre-development discharge of stormwater from the site. Included within the calculations by these two experts, concerning post-development volume of stormwater to be discharged, is an analysis of the quantity of water to be retained in the retention area of the proposed project. The discharge from the retention area is controlled by the above-mentioned weir and bleeder notch. The retention area proposed by the applicant is to be used both for discharge of dewatering water from the mine pit (under the previously issued industrial water permit) as well as for retention of stormwater. This weir and bleeder notch is designed to be at an elevation which only allows discharge of a volume of water representing the volume of stormwater entering the retention area over a given period of time, and not the dewatering water from the site, which may contain rock, dust in suspension, and other sediments. The previous permit granted to the applicant, as well as the permit sought in this proceeding, would require (as all parties agree) that the dewatering volume of water, representing the water pumped from the mine pit, will totally remain on the site. The project as designed is reasonably assured to be capable of retaining all such dewatering mine pit water on-site. One critical factor considered in determining the design and site for the retention area (155 acres) and in setting the bleeder notch elevation for discharge of stormwater volume, is the infiltration rate from the retention area into the ground beneath it. The Respondent Harper Brothers established (through these uncontradicted expert witnesses) that the infiltration rate is 43,000 gallons per day per acre of the retention area for a one-foot elevation of water in that retention area. One of the factors computed into the infiltration rate calculation is the "transmissivity rate." The transmissivity rate is 200,000 gallons per day per foot in the shallow or surface aquifer at the project site. Petitioner's expert, Mr. Bruns, conceded that if that rate is correct, as it was established to be, that the post-development volume of discharge leaving the project site would not exceed the pre-development volume of discharge, if the maximum pumpage rate into the retention area from the pit did not exceed 8.5 million gallons per day, and it is so found. Parenthetically, it should be noted that the Petitioner presented no testimony of its own concerning infiltration rates or transmissivity rates. Neither did the Petitioner's expert Mr. Bruns make any calculations of quantity of discharge from the site in either a pre-development condition or post-development condition, nor was a water management or hydrologic study of the drainage basin (approximately 6 square miles) made by Petitioner's expert witness, to assist in analyzing quantity of discharge. Under certain hypothetical conditions it would be possible for dewatering discharge water from the mine, as a volume of water, to be discharged, commingled with stormwater discharge, from the retention area. Thomas Missimer, testifying as an expert witness in the fields of hydrology and water quality for Harper Brothers, was uncontradicted. His studies and calculatiops in evidence established that, with regard to the infiltration rate downward into the soil under the retention area, and the amount of water pumped into the retention area, that equilibrium is reached when pumping into the retention area reaches 8.5 million gallons per day. That is, approximately 8.5 million gallons per day infiltrate downward into the soil and thus leave the retention area and thus an 8.5 million gallon pumpage rate per day would result in a static water level in the retention area, aside from evaporation. If the Respondent pumped in excess of this figure, which might be possible under its present mine dewatering industrial use permit, then the pumpage figure might exceed the equilibrium figure and cause the volume of water discharged off the site to exceed that volume which only represents stormwater. Accordingly, the parties stipulated that the maximum daily pumpage rate of 8.5 million gallons per day would be included as a condition in the permit, if it were issued to the Respondent, such that, based upon the uncontradicted infiltration data, that the limitation to a maximum pumpage rate into the retention area of 8.5 million gallons per day from the mine pit, would be permissible. In view of this stipulation, Petitioner withdrew its contention that the post-development volume of discharge water leaving the site would exceed the pre-development volume of discharge. It was thus shown that at the maximum pumpage rate of 8.5 million gallons per day no mine dewatering discharge (as a volume of water) will leave the retention area. NON-ALTERATION OF HISTORICAL DRAINAGE PATTERNS The Petitioners also contend that the supposed alteration of historical drainage patterns by this development at the site will cause additional flooding to the Petitioner's access road to their property (residence and nursery) by the road known as Mallard Lane. In that connection, the historic pattern of stormwater discharge off the project site or its geographical area, is figured into the analysis of pre-development water volume discharge versus post-development discharge. This project, like others of its type, is mandated by the rules at issue to not alter the pre-development patterns of water discharge off the site area so as to adversely affect the property and landowners off the site. Although the pre-development discharge is generally observed and calculated by looking at a site before the development involved in a permit application takes place, in the instant case, Harper Brothers, Inc., by the authority of its previously issued dewatering and industrial water use permit had already initiated its mining operation and so pre-development conditions as they relate to this permit were not directly, physically observable. Accordingly, a hydrologic study of the drainage basin in which this project is located was performed, and, in conjunction with the use of aerial photography and U.S.G.S. quadrangle maps, the perimeter of the basin was determined and an analysis of the historical pattern of flow in the drainage basin was done. The general flow of water in the drainage basin historically is from northeast to southwest, with an ultimate discharge into the "no-name" slough, a "cypress head" or slough which generally flows in a westerly and southwesterly direction from the area immediately adjacent to the project site. Internally within this drainage basin, some old pre-development north/south dykes have blocked some of the westerly flow which historically existed at the site, thereby causing some of the water to flow in a northwesterly direction until it reaches the northern end of the north/south dykes, thence returning to the generally southwesterly drainage pattern, ultimately ending up in the slough system. A small area of farm fields was located north of the east/west access road to the site, and southerly of an existing east/west line of farm dykes, and may have drained in a southerly direction before development. There is currently no information and no evidence of record concerning how this farm field area was drained. The drainage from this area now, however, is insignificant and is calculated at approximately one cubic foot per second as a maximum rate. As the calculated post-development discharge from this project site is approximately 9 cubic feet per second, even if it be assumed that the drainage from the old farm field should be added to the post-development discharge rate from the project site itself, such an addition would only equal and not exceed the historic, pre-development discharge rate of ten cubic feet per second. The flows in a southerly direction are currently blocked by the east/west access road to the Harper Brothers' site, used by Harper Brothers. In a predevelopment condition however, the same situation existed since the southerly flow was similarly blocked by farm dykes which existed in the pre- development condition. The proposed facility is designed to have stormwater which falls on the entire project site to be pumped into the retention area. The volume of stormwater permitted to be discharged will discharge from the retention area via the above-mentioned outfall structure and will be routed westward through the double-dyke system down a drainage swale on the north side of the entrance road, and ultimately into the no-name slough. Thus, the historic drainage pattern of the basin from the northeast to the southwest will not be significantly altered by the project as designed and proposed. The project generally preserves this historic drainage pattern by discharging the drainage within the basin into the "no-name" slough as occurred in the pre-development condition which, when the above-described pre-development and post-development discharge rates are compared reveals that there will be no adverse alteration in terms of either a dearth of or excess of water supply to this natural slough system. The Petitioner's access road, North Mallard Lane, running from north to south, accessing Petitioner's property west of the project site, is indeed subject to inundation, but was subject to such inundation in the pre-development condition of the project site. This is because the slough crosses this access road. Since the post-development condition does not alter the historic patterns of drainage to any significant degree, and does not represent an alteration in the volume of discharge from the project site area over that in the historic, pre-development condition, no additional flooding to the Petitioner's access road will be caused as a result of the project installation and operation. The flooding being caused to the Petitioner's access road, indeed was shown to be related in part to culverts of insufficient size installed by Lee County, so that water tends to stand on the road surface as opposed to draining under and away from it. NON-ALTERATION OF THE pH OF RECEIVING WATERS It is undisputed that the subject project, like all such projects, under the permitting authority of SFWMD, must meet state water quality criteria contained in Chapter 17-3, Florida Administrative Code. The design of such a surface water management system must include "best management practices" (BMP's) in order to satisfy the district's design criteria. BMP's are techniques which are incorporated into the design of such a system to enhance water quality such as the use of swales, retention ponds, and gravity structures. Given that the project will utilize a retention area, grassed swales and other well accepted water management structures, the design was shown to comport with "best management practices." Water quality measurements for the only water quality parameter in dispute, that of pH, were taken on the project site using standard, accepted scientific methods and U.S. Geological Survey Water Quality Standard sampling techniques. The tests revealed a pH in the retention area itself of 7.91 pH units. The pH in the pit area was 7.8 pH units and in the off-site water in the slough, the pH was 7.3 units. The water discharge from the retention area would be a combination of stormwater (rain water) which is approximately 6 pH units in the geographical area involved, and the retention area water at approximately 7.8 pH units. The precise pH of this discharge water would depend on the quantities of water from each source, but was shown to be almost neutral or approximately at a pH of 7. Thus, the discharge from the retention area of the commingled dewatering and stormwater, if such occurs, will not alter the receiving waters one full pH unit. Upon issuance of the permit, the applicant will still have to comply on a continuing basis with the water quality parameters of Chapter 17-3, Florida Administrative Code, and the staff of SFWMD will continue water quality monitoring after the permit is issued. There has thus been no showing that commingling of dewatering water and stormwater in the retention area and the discharge of such commingled waters to the receiving waters of "no-name" slough would affect the pH of that receiving water in a manner to exceed existing, permissible pH parameters and adversely affect water quality. Expert witness Serra testifying for the district as well as for Harper Brothers, has studied similar mining operations. Such operations, utilizing similar water management procedures, have not caused any water quality violations related to discharges of commingled dewatering and stormwater, including no violations of the pH parameters. Finally, near the conclusion of the proceeding, Petitioner, in effect, abandoned its dispute regarding the issue of compliance with the pH water quality parameter.
Recommendation Having considered the foregoing Findings of Fact and Conclusions of Law, the candor and demeanor of the witnesses, the evidence of record and the pleadings and arguments of the parties, it is, therefore RECOMMENDED: That a Final Order be entered by the South Florida Water Management District authorizing issuance of a surface water management permit to the applicant herein for the proposed surface water management system, imposing upon the applicants the limiting and special conditions enumerated in the district staff report depicted in Exhibit 2 and incorporated by reference herein, and additionally, those two special conditions set forth immediately above.
