Findings Of Fact Based on the testimony of the witnesses and their demeanor while testifying, the documentary evidence introduced, the proposed findings of facts and recommended orders filed by the parties' counsel, and the arguments and citations of authority cited therein, the following relevant facts are found. 1/ This action concerns a parcel of land owned by Ronald E. Dowdy and his wife, Mary Ellen Dowdy, located at 7630 Lake Marsha Drive, Orlando, Florida. The Department does not claim, other than regulatory authority, ownership to the land in question. On March 15, 1978, Petitioner submitted to the Department a dredging and fill permit application, file No. 48-8093-4E., to deposit 200 cubic yards of fill material waterward of the line of ordinary high water, adjacent to Petitioner's upland property on Lake Marsha. The area proposed to be filled measured 150 feet along the shoreline, 55 feet between the line of ordinary high water and ordinary low water, and 12 inches deep. (Petitioner's Exhibit 2; D.E.R. Exhibit 9.) On June 15, 1978, the Department gave notice of its intent to deny Petitioner's permit application, stating with particularity the specific ground on which the denial was based and allowing Petitioner fourteen (14) days in which to petition for a hearing on the denial. Within thirty (30) days of the filing of the petitioner's application, he was advised that clearance and/or approval was necessary from the Department of Natural Resources. A Final Order denying application for permit was issued June 23, 1978. Petitioner did not file a petition pursuant to Chapter 120, Florida Statutes, seeking review of either the intent to deny letter or the Final Order until January 15, 1979. The Department waived the time requirement for filing the petition. On or about August 3, 1978, Petitioner caused to be deposited large quantities of fill in excess of the 200 cubic yards applied for along approximately 380 feet of shoreline between the line of ordinary high water and ordinary low water adjacent to his upland property. (Petitioner's Exhibit 2 and D.E.R. Exhibits 1 and 2.) Although Petitioner did not obtain a permit from the Department prior to commencement of the fill work described above, Orange County issued a permit (see Petitioner's Exhibit 2) which specified that the Department permit would have to be obtained prior to commencement of the fill work. The county permitted the Petitioner to fill an area along 150 feet of shoreline while the petitioner filled the entire length of the shoreline, i.e., 380 feet. As of the hearing date, Petitioner had not filed an application for a permit from either the county or the Department for the excess fill. Prior to the time that the Petitioner undertook the filling project, he met with employees of the Department who advised that a permit would be necessary prior to commencing the fill work. Department employees suggested that the State would look favorably on a reduced fill project of somewhere between 50 to 75 feet along the lake shoreline. (D.E.R. Exhibit 8.) The bulk of the fill area as completed, lies below the ordinary high water line of Lake Marsha, i.e., below the elevation line of 127 feet. (Petitioner's Exhibit 2.) Mr. Robert Day, a pollution control specialist employed by the Department as an enforcement investigator, observed the filling activity as it was taking place from the movement of fill by bulldozer to the sodding of the newly created fill area. (D.E.R. Exhibits 1 and 2.) Upon discovery of the Petitioner's filling activity without a permit, the Department attempted to notify him of the violation by means of a warning notice sent by U.S. Mail, certified, return receipt requested, which Petitioner did not claim. The Department thereafter sent Petitioner a telegram which resulted in a meeting in the Department's office in Orlando. (D.E.R. Exhibits 3, 4 and 5.) Richard Hoffman, district conservationist with the U.S. Department of Agriculture, Soil Conservation Service, was qualified as an expert in the collection and identification of soil core samples. Mr. Hoffman testified at length on a series of core samples taken on the Dowdy property confirming the fact that the Petitioner had placed fill on vegetated muck and that all but one of the core samples were below the high water line. (Petitioner's Exhibit 2 and D.E.R. Exhibit 7.) James Morgan, an environmental specialist of the Department, was qualified as an expert witness in the processing and appraisal of dredge and fill permit applications and their impact on water quality and wetlands ecology. Mr. Morgan advised the Petitioner on February 14, 1978, several months before the actual filling activity, that it was necessary to obtain a permit from the Department pursuant to Chapter 17-4, Florida Administrative Cede. Again, on March 16, 1978, at a meeting with Petitioner, Mr. Morgan advised the Petitioner of the necessity to obtain a permit before any filling was done. Additionally, he advised and suggested to Petitioner that with respect to his proposed activity, the Department would look favorably upon a modified application requiring a fill area of 50 to 75 feet of the lake's shoreline. Upon receipt of Petitioner's application, Mr. Morgan conducted a permit application appraisal (D.E.R. Exhibit 9) and found that the area proposed to be filled contained deep muck deposits and was dominated by the vegetation, maidencane, with a lesser abundance of arrowhead, pickeral weed and pennywort. The dominant species was maidencane, which along with arrowhead and pickeral weed, are species found in the vegetative index for submerged lands as set forth in Section 17-4.02(17), Florida Administrative Code. (See D.E.R. Exhibits 9 and 10.) Approximately 50 percent of the shoreline of Lake Marsha has been developed with the consequent elimination of marsh and wetland vegetation fringes of the lake. The aquatic vegetation found on the Dowdy property prior to filling performed functions of assimilating nutrients and filling deleterious substances from the waters of Lake Marsha and provided wildlife habitat. This assimilation process enabled and assisted the shoreline plants ability to absorb water containing dissolved pollutant substances which are utilized for plant food. The aquatic vegetation also filters suspended solids from the lake water. This assimilation and filtration process helps preserve water quality in a fresh water lake by both filtering runoff from the upland and cleansing the water of substances found in the water body itself. (D.E.R. Exhibit 9.) This process is commonly referred to as the "kidney effect". The fill which has been placed in the submerged land aquatic community will, as testified by the Department's witnesses, totally eliminate portions of the kidney of Lake Marsha and has been replaced with sod which carries the potential for causing further pollution of the waters of Lake Marsha. Testimony reveals that the fill will increase the nutrient load in the lake and dramatically decrease its ability to cope with the increased load. It is predicted by the Department's witnesses that the impact of the fill on the water quality of the lake will be significant as a substantial portion of the lake's littoral zone has been substantially eliminated. This, according to witness Morgan, can lead to the eutrophication of Lake Marsha end a resultant lower equilibrium based on poor water quality. (D.E.R. Exhibit 11.) According to Morgan, the parameters which are expected to be violated by the fill and the resultant elimination of a submerged land aquatic plant community include phosphorous and nitrogen which are classified as nutrients under Section 17-3.061(2)(i), Florida Administrative Code, and turbidity, under Section 17-3.061(2)(g) Florida Administrative Code. (D.E.R. Exhibit 9, part 2.) Testimony reveals that a correlation exists between the degree of shoreline development of Central Florida lakes and the water quality of such lakes. This correlation is direct and reveals that the greater the degree of shoreline development, the greater the reduction of the lake's ability to compensate for nutrient load going into the lake and, thus, lower water quality. (Testimony of Morgan and Hulbert, T.R. pp 138-139; 177-180.) Witness Morgan testified that by restoration of the Petitioner's fill site to its original contours and elevation, the aquatic vegetation which once thrived on the site will reestablish itself and the consequent restoration of the lake's "kidney effect". James Hulbert, a Department District Biologist qualified as an expert in the area of water pollution biology and wetlands ecology, confirmed witness Morgan's testimony regarding the impact of water quality based on Petitioner's filling, the value of the wetland vegetational community which was, according to him, destroyed by the filling, including protection of uplands and its role as a source of food and shelter for the lake's aquatic life. Witness Hulbert also confirmed the testimony of witness Morgan to the effect that a direct correlation exists between the degree of shoreline development in central Florida lakes and the lowering of water quality in such lakes. Witness Hulbert testified further that submerged lands such as the ones filled by Petitioner assimilate nutrients for preserving fisheries of fresh water lakes. Mr. Hulbert also testified that dissolved oxygen levels are expected to be degraded with severe fluctuations which would result in the dissolved oxygen levels of as low as 0.0, below the standards of Chapter 17-3, Florida Administrative Code. This increased nutrient load will, according to Mr. Hulbert, result in proliferation of such existing exotic plant species such as hydrilla and water hyacinths, and an acceleration of the lake's eutrophication. Mr. Hulbert summarized the long- range impact of the fill as both measurable and substantial and concluded that the degradation process will be steady and gradual. Robert Bell, a real estate appraiser licensed in the State of Florida as a broker, indicates that there are other valuable uses of Petitioner's property other than filling the entire shoreline. Such uses, according to Bell, include the construction of a boardwalk, a deck, gazebo, a boat house, and even partial filling of the shoreline area for access to the water. The Department incurred expenses and costs in preparation of this proceeding for purposes of tracing, controlling, and abating the pollution sources created by the Petitioner's dredge and fill activities in the amount of $201.88. (D.E.R. Exhibits 14 and 15.)
Recommendation Based on the foregoing findings of fact and conclusions of law, it is hereby
Findings Of Fact Lake Powell Improvement Corporation is a consortium of interested owners of land comprising the majority of the Lake Powell shoreline. Camp Helen Company, one of its members, owns lake property which was formerly operated as a recreational facility for associates of Avondale Mills. Camp Helen Company now holds the property for the possibility of future development. George Jeter is one of approximately 76 persons who sent a form letter to the Department of Environmental Regulation (DER) in opposition to the designation of Lake Powell/Phillips Inlet as an Outstanding Florida Water (OFW). The rule-making proceeding to designate Lake Powell/Phillips Inlet an OFW was initiated with a petition filed on June 11, 1987, by the St. Andrews Bay Resource Management Association, a private citizens' organization formed in 1986 to help protect wildlife and resources in the St. Andrews Bay area. A public workshop was conducted by DER on September 6, 1990, in Panama City, Florida. Approximately 70 persons attended the workshop, including Bay County residents, Walton County residents, Lake Powell area property owners and representatives from various organizations. Craig Crockard, Vice President of Lake Powell Improvement Corporation, opposed the designation based on alleged degradation of property values and tax base, negative impact on growth and increase in road maintenance costs. Agency staff encouraged workshop participants and members of the public to submit information, including economic information, that would aid in the decision-making process. Only general and speculative information was received, with the exception of a response from the Department of Transportation that costs of future construction and expansion of the Phillips Inlet bridge, part of four-laning Highway 98, would be increased by $1.5 million as a result of the OFW regulations. DER sent a letter to Craig Crockard, received on April 2, 1991, requesting specifics as to the property owners' development plans and estimated economic impacts by April 5th. Crockard responded that the deadline was too short and that it was obvious that the decision had already been made. At no time, up to and including the hearing before the Environmental Regulation Commission (ERC), did Petitioners or other opponents provide information as to specific economic impacts of the proposed designation. The proposed rule would add the following area to rule 17- 302.700(9)(i), F.A.C. specifying special waters under the OFW designation: Special Waters * * * Lake Powell, Phillips Inlet, and all tributaries to Lake Powell as bounded by the following described line: Begin at the Northwest corner of Section 26, Township 2 South, Range 18 West; thence East to the Northwest corner of Section 29, Township 2 South, Range 17 West; thence South to the Northwest corner of the SW 1/4 of Section 29, Township 2 South, Range 17 West; thence East to the West line of Section 27, Township 2 South, Range 17 West, thence South to the mean high water line of the Gulf of Mexico; thence meander Northwest along the mean high water line to the West line of Section 35, Township 2 South, Range 18 West; thence North to the point of beginning ( - - 91). * * * In making its determination to recommend OFW designation for Lake Powell to the ERC, the Department compared Lake Powell to other water bodies. Lake Powell was found to be exceptionally ecologically and recreationally significant in terms of size, water quality and recreational usage. The Department makes its determination as to whether the proposed water body is exceptional by making direct comparisons to features of other water bodies, and by relying on the professional judgements of others familiar with the particular class of water bodies. Lake Powell has been compared by professionals familiar with other water bodies in the area and in their opinion it has exceptional value as an ecosystem. The Department relied on professional judgement of this type as well as its own findings when making the determination that Lake Powell was exceptional. Lake Powell is located in Bay and Walton Counties in Northwest Florida adjacent to the Gulf of Mexico. Its total surface area of 737 acres makes it the largest by far of any of a series of similar lakes in the area. Seven small streams provide fresh water to the lake; periodically Phillips Inlet, connecting the lake to the Gulf of Mexico, opens or closes. When the inlet is open, the lake becomes estuarine in nature. Most of the shoreline of Lake Powell is still undeveloped and the lake is significant in that it has experienced only minimal adverse impact from human activity. There are no permitted point source discharges to Lake Powell. It is basin-shaped, with a shallow shell, steep sandy slopes, and a flat bottom ranging from approximately 10 to 20 feet deep. Silty, high organic sediments in the water are amenable to degradation and are uniquely sensitive to pollution. Restricted flushing and the opportunity for development growth in the area add to that sensitivity. Lake Powell is a Class III waterbody. Water quality in the lake is good, and meets Class III standards; some parameters are as good as Class II standards. The low dissolved oxygen level in the lake is a result of natural conditions, is not a result of pollution, and is therefore not a violation of the Class III standard for dissolved oxygen. Lake Powell is one of the lakes in the state that is part of the water quality sampling effort known as Lake Watch. A benefit of OFW designation to this effort will be that Lake Powell, absent degradation, can serve as a control lake to compare other Lake Watch lakes throughout the State. At least 170 species of birds, (trust resources of the US Fish and Wildlife Service), have been observed and are dependent on Lake Powell. Unusual species include the piping plover (federally and state designated threatened), snowy plover (state designated threatened), least tern (state designated threatened), and bald eagle (federally designated endangered and state designated threatened). These species have a direct dependence on Lake Powell for habitat, feeding, or nesting areas. They are dependent on non-trust species such as small fishes which could be impacted by chemicals introduced to the lake. Edwin James Kepner, a biologist for the National Marine Fisheries Service, has identified three new species of nematodes which so far have been uniquely found in Lake Powell. Although nematode species are among the most abundant on earth (97,000 individuals may be found in a single rotting apple), they are a highly significant part of an ecological system and must be understood and studied for any understanding of marine communities. The lake supports a diversity of animals. At least 87 species of macrobenthic invertebrates and 67 species of fin fish inhabit the lake, a diversity based on the system's intermittent connection to the Gulf and the lake's relatively pristine condition compared to other lakes. One would expect to find even more diversity, 3 to 4 times more species, if better and more accurate sampling methods were employed. Lake Powell presents a unique nursery area, since most large predator fishes do not have access to it. The lake presently supports a variety of recreational activities, including canoeing, sailing, windsurfing, water-skiing, fishing, crabbing and picnicking. This recreational use has increased during the last five years. Lake Powell is ranked 36th out of 361 lakes statewide in a 1982 study of recreational usage. In terms of potential to the public for recreational usage, Lake Powell has three public access points to the lake, and a possible fourth. Public access is gained by a Bay County public park and by way of Gulf View Drive, which is owned by Bay County and used to launch boats. There is a public dock in Walton County which is also used extensively. The fourth access is currently the subject of an inquiry by the Bay County Audubon Society. The unusual quality of recreational experience lies in the pristine nature of the lake and the fact that it is located not far from the Miracle Strip in Panama City Beach. The ERC Commissioners, who were taken on a tour of the lake, were able to contrast the two areas and found that Lake Powell had unusual recreational value. Lake Powell provides an exceptional educational opportunity, and with its many different types of habitat it is a compact, manageable educational laboratory. As compared to the St. Andrews Bay System it would be much easier to collect samples, obtain information on biotic communities and generally conduct research on the effectiveness of regulatory programs, due to the manageable size of the lake. The proposed amendment to Rule 17-302.700(9)(i), F.A.C., to designate Lake Powell as an OFW would potentially affect future Department permit applicants by requiring they provide the Department with reasonable assurances that the proposed project is clearly in the public interest and that the proposed project would not lower existing ambient water quality standards (Rule 17-4.242, F.A.C.); by requiring that direct stormwater discharges into the lake include an additional 50% treatment level (Rule 17-25.025(9), F.A.C.); and by reducing the exemption for private residential docks from 1000 square feet to 500 square feet (Rule 17-4.04(9)(c), F.A.C.). These requirements will result in increased costs to permit applicants, although the costs cannot be calculated at this time since there are no such projects firmly proposed to the Department. The primary beneficial effect of the proposed rule would be the protection of future water quality based on existing ambient water quality standards at time of OFW designation. Pursuant to Section 120.54(2), F.S., an Economic Impact Statement (EIS) was prepared by the Department. Section 120.54(2)(b), F.S., requires the statement to include: * * * An estimate of the cost to the agency of the implementation of the proposed action, including the estimated amount of paperwork; An estimate of the cost or the economic benefit to all persons directly affected by the proposed action; An estimate of the impact of the proposed action on competition and the open market for employment, if applicable; A detailed statement of the data and method used in making each of the above estimates; and An analysis of the impact on small business as defined in the Florida Small and Minority Business Assistance Act of 1985. Additionally, Rule 17-302.700(4)(e) provides: An economic impact analysis consistent with Chapter 120, shall be prepared which provides a general analysis of the impact on growth and development including such factors as impacts on planned or potential industrial, agricultural, or other development or expansion. It is undisputed that the EIS properly addressed the costs of implementation to the Department. The EIS identified the kind of Department permit applicant that would potentially be affected by the rule amendment, and what kinds of developmental impacts could be expected by operation of other Department rules. The EIS did not identify any specific costs that would be attributable to the rule, as the Department was unaware of any specific development plans for the lake that would be subject to the Department rules. Existing development activities are grandfathered and would not be affected by the more stringent requirements. The Department stated in its EIS that the overall costs imposed on future development due to the proposed OFW designation would depend on both the nature of the development and its impact on the ambient water quality of the lake. Since the type and nature of future development in the area is uncertain, an estimate of the potential aggregate costs associated with the proposed OFW designation could not be made at the time the EIS was prepared. The EIS properly addressed the costs of the proposed rule to the parties, based upon the facts as known to the Department. The benefits to the public of the rule were stated to be largely environmental, as a result of protection of future ambient water quality standards in the lake. The EIS cited an economic benefit to land owners around the lake in the form of enhanced property values due to water quality protections of the OFW designation, water quality being an important variable in determining property values of waterfront property. That property values would be enhanced is based on the DER economist's study of another state's experience and experience with OFW designation in other Florida counties. The EIS properly addresses the benefits of the rule. The EIS states that there will be no significant effect on competition as a result of the proposed OFW designation; Petitioners have not presented any evidence to the contrary. The EIS adequately addresses the rule's effect on competition. The EIS states that the proposed OFW designation is not expected to create any significant adverse disproportionate impacts on small businesses, as required by Section 120.54(2)(b)5., F.S. As Petitioners have not introduced any evidence to the contrary, the EIS adequately addresses this issue. The EIS states that appropriate economic analysis techniques were employed preparing the EIS. Petitioners participated in the rulemaking process; they attended the Panama City workshop when economic information was solicited; they submitted written comments, none of which provided specific economic information; and they participated in the ERC hearing but offered no evidence to the Commission regarding economic impacts of the rule. The type of information they suggest that the Department should consider was not submitted by them, or anyone else, during the rulemaking process or this hearing. The evidence shows that the Department considered all comments submitted throughout the rulemaking process in making the recommendation of OFW designation to the ERC. The EIS properly explains the data and methodology used in its preparation, and this data and methodology was adequate to estimate the economic impacts of the rule. In January 1991, the Bay County Board of County Commissioners amended the County's comprehensive plan to provide special protection for Lake Powell. These provisions include more stringent requirements for stormwater retention and detention, an objective to maintain Lake Powell's water quality at its present level, restriction on use of household septic tanks, designation of a low-density residential zone, and prohibition of point source discharges which would lower existing water quality. (Joint Exhibit #1, Appendix D) Both parties have invoked the plan amendments for their own purpose. Petitioners argue that the plan amendments provide the same or greater protection than the proposed OFW designation and that the designation is not needed. This argument ignores the fact that at least 10% of the lake lies within Walton County, outside Bay County's jurisdiction. DER did not require Bay County to amend its plan and could not require it to maintain the new Lake Powell protections indefinitely. The OFW designation does not detract from or conflict with the local government's commendable initiative, but rather augments it. Respondent, DER, addresses the plan in its modified EIS where it discusses the contention by the Department of Transportation (DOT) that OFW designation will add $1.5 million in costs to widen a road at the Phillips Inlet bridge. DER's economist concedes that designation will result in additional costs and has discussed that in the EIS. Because he has not received back-up data from DOT he is unable to confirm that the cost will be as much as DOT asserts. He also attributes the increase to the new stormwater requirements of the Bay County comprehensive plan, and concludes the additional costs due to OFW designation might be zero. (Joint Exhibit #2, p. 7) Even if misplaced, the attribution of costs does not invalidate the EIS or the proposed designation. The EIS generally describes potential costs and provides a basis to weigh the environmental, social and economic costs against the environmental, social and economic benefits. In summary, the facts above support the ERC's finding that the waters selected for designation are of exceptional recreational or ecological significance and the benefits of designation outweigh its costs.
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.

Findings Of Fact Mr. Cutter has resided in Taylor County, Florida since 1974. His home is approximately 8,000 feet southwest of the Fenholloway River on the north side of Courtney Grade Road. DEP is responsible for administrating the Water Quality Assurance Trust Fund. DEP's responsibilities include the undertaking of water supply restoration projects in appropriate circumstances. In administering this trust fund, DEP determines whether specific ground water supplies are contaminated. This determination generally requires DEP to evaluate whether a given water supply meets primary drinking water quality standards. A primary drinking water standard is a regulatory criterion adopted by the state pursuant to delegated federal authority. Such a standard refers to a certain maximum level for a given contaminant which, if exceeded, represents a health risk. If DEP finds that a primary drinking water standard is violated, it performs a cost analysis to determine the appropriate means of restoring or replacing a water supply source. In the late 1980's, DHRS received complaints from Taylor County residents that water from their private wells looked, smelled, and tasted bad. DHRS asked DEP to investigate those complaints. DEP's initial investigation of ground water quality did not reveal a public health threat. Nevertheless, DEP decided to proceed on the assumption that industrial effluent in the Fenholloway River could represent a public health threat. DEP first considered the potential of conducting chemical analysis of ground water to detect the presence of chemical markers that would indicate the presence of water from the Fenholloway River. In order to do this, DEP would have to isolate a chemical compound from the industrial effluent in the Fenholloway River that would serve as a "marker" for contaminated effluent. DEP attempted to determine the influence of the Fenholloway River using a test measuring non-purgeable total organic halides, or NPTOX, as a chemical marker. DEP's projections relying upon NPTOX as an indicator for river water proved to be unreliable. DEP correctly rejected the use of NPTOX as a chemical marker because it occurs naturally and does not provide a clear indication as to whether river water influences ground water. Moreover, DEP identified laboratory quality assurance problems for tests using this chemical. DEP's scientists do not know of any practical chemical marker that can identify mill effluent in river water. Research is emerging which may identify a chemical test which will reveal the presence of effluents from kraft paper mills. However, the academic community has not yet validated their use. After the shortcomings of chemical analysis became evident, DEP decided to conduct a ground water study to reach conservative findings regarding the extent to which water from the Fenholloway River could potentially impact ground water supplies in a worst case scenario. DHRS agreed to certify that it would be in the interest of public health to connect homes to a public water system if DEP could identify a corridor where river water influenced ground water. As a result of the ground water study, DEP prepared and adopted the 1995 report titled "Delineation of Ground and Surface Water Areas Potentially Impacted by an Industrial Discharge to the Fenholloway River of Taylor County, Florida" (1995 Report). The 1995 Report identified a conservative potentially impacted corridor within which water from the Fenholloway River might interact with ground water in the adjoining aquifers as well as the potential impact of river flood waters on ground water. Buckeye is a softwood kraft pulp specialty mill that has been in operation in Taylor County since 1954. It discharges treated effluent into the Fenholloway River in accordance with permits from DEP. The mill discharges effluent upstream of U.S. 19 Bridge. This discharge creates a mounding effect, i.e. an artificial high level within the river. Because the river downstream of the discharge point is maintained at an artificially high level during drought conditions, a "mound" of water forms where the water level in the aquifer connects to the river. During a dry season, this discharge will be maintained, but the aquifer on both sides of the river will continue to drop due to a lack of recharge from rainfall. The river generally runs from east to west through Taylor County. It starts in the San Pedro Bay at 100 feet above sea level and ends at the Gulf of Mexico at sea level. Ground water (subsurface water) moves from higher to lower elevations of the water table. Elevations (contours) of equal ground water levels can be mapped just as elevations of land surfaces are mapped. Ground water contour lines (sometimes called equipotential lines) depict points of equal ground water elevation. Direction of ground water flow is always at right angles to the contour lines. Ground water is a dynamic system impacted by rainfall, which adds water to the system, and discharge points, which take water from the system. Water is constantly entering (recharging) or leaving (discharging) the aquifer, which causes the ground water levels to be continually changing. The Floridian aquifer system underlies all of Florida, including the study area of the 1995 Report. The aquifer at issue here is unconfined from San Pedro Bay to the coast. Potentiometric (aquifer water level) elevations of the Floridian aquifer in the study area of 1995 Report show that ground water moves southwesterly. The dominant direction of the ground water flow in this area is parallel to the river. Under normal conditions, with normal rainfall, the river is a focal point for ground water discharge. In this situation, rain recharges the shallow aquifer so that the water level elevations in the aquifer are higher than the water level elevations of the river. Consequently, ground water moves into the river, making it a "gaining stream." In periods of drought when the rainfall is deficient, the recharge is deficient and the water level in the aquifer can decline to points that are lower than the elevation of the water level in the river. In that instance, water can leave the river. If water migrates from the river into the ground water, the river is called a "losing stream." When water leaves the river and migrates outward, it will be influenced by the dominant regional flow that is parallel to the river and downstream. River water can migrate outward a limited distance before it becomes influenced by the regional flow and migrates back to the river. Migration back to the river occurs when water level elevations in the aquifer are higher than they are in the river and the river becomes a "gaining stream." The purpose of the 1995 Report was to define a potential corridor of river influence, using the worst case scenarios in all hydrogeologic conditions. It relied primarily on potentiometric (aquifer water level) studies, as opposed to a chemical analysis of ground water quality. DEP's report relied on differences in water elevations in the river and ground waters. The 1995 Report also relied upon United States Geological Survey (U.S.G.S.)/ U.S. Department of Housing and Urban Development flood prone area maps to delineate the extent of river water flooding on surrounding land surfaces. The area of the study was from east of the mill to County Road 356 in the west, including U.S. 98 to the north and Courtney Grade Road to the south. DEP has not discriminated against certain residents of Taylor County by not extending the geographic boundaries of the study area. The study did not end at Golf Course Road. In order to prepare the MODFLOW model which ultimately led to the MODPATH model, DEP installed additional monitor wells to the west of Golf Course Road. These additional wells provided DEP with ample water level data to perform the models. The monitor wells were more concentrated near the discharge point of Buckeye's mill. However, there were greater fluctuations in water levels in that area. DEP's decision to limit the study to the area depicted in the report was based on technical and policy considerations. Water levels in the areas to the west of the study do not fluctuate very much. Additionally, the influence of the tide from the Gulf of Mexico decreases the impact of river water on ground water south and southwest of the study area. The population in these areas was relatively low. Because the population of Taylor County is dispersed, it is not cost-effective or feasible for DEP to consider the extension of water lines beyond the boundaries of the study area. Mr. Cutter lacks standing to claim that the study did not extend far enough to the west. The western portion of the river beyond the limit of the study could not adversely impact ground water supplying the well on Mr. Cutter's property. DEP collected sufficient data and made an appropriate analysis of the total area depicted in the 1995 Report. The 1995 Report did not use water quality data as a primary or sole indicator of effluent extent. However, it did consider some supplemental chemical concentrations to evaluate water quality. These concentrations were always at or below normal background levels and therefore were consistent with the conclusions in the report. DEP used three techniques to determine the furthest lateral distance that river water could potentially migrate into ground water in the adjoining aquifers. Two techniques (cross-section model and steady-state ground water model) were used to determine the extent of migration during the worst case dry season scenario. The third technique (flood season map) was used to determine the extent of influence on ground water during the worst case river flooding scenario. The cross-section technique used to model the worst case dry season scenario relied upon historical data from the driest period on record (using data from Suwannee River Water Management District, U.S.G.S. and Buckeye monitoring wells), which was April 2, 1989. Using this data, DEP prepared a potentiometric map. A computer program interprets data from a contour map and, given horizontal and vertical axes at given points, produces cross-sections. The cross-sections are made at various angles of the river to determine "stagnation" points," i.e. points where the ground water gradient between the aquifer and the river is zero. DEP staff connected the stagnation points revealed by the cross- section method and transposed them onto a potentiometric map for May 25, 1994 (a dry period where sufficient data was available). This process allowed DEP to define the total area where the river would impact the aquifer during the dry season. The results of the cross-section technique showed that the migration of river water into ground water occurs during dry seasons almost entirely on the north side of the river. It confirmed the analyses of the MODFLOW and MODPATH models discussed below. DEP used a steady-state simulation flow mode as one of the three study techniques in the 1995 Report; it was based on the worst case dry season scenario of April 25, 1989. This model allowed computer tracking of simulated particles (representing river water) in a portion of the 17-mile (north-south) by 20-mile (east-west) grid used in the model. The computer model shows how simulated particles during the worst case dry season conditions: (1) enter the aquifer when the river is higher than the ground water; (2) move away from the river when the river elevation is higher than water level elevations in the adjacent aquifer; (3) reach a "stagnation point" where the elevation of river water that has entered the aquifer is equal to that of the unaffected portion of the aquifer; and (4) subsequently flow parallel with the river and eventually back to the river. The objective of the steady-state ground water flow model (MODFLOW) is to incorporate the best available data so that calibration of model parameters can be accomplished by using measured ground water heads for a specific "snap shot" in time. Once an acceptable calibration of the model is obtained by minimizing the residuals of modeled versus measured heads, then the water budget is decreased by a recharge package so that the model heads closely reflect an observed "worst case" dry season head distribution. After an acceptable dry season head match is obtained, a particle tracking program (MODPATH) is used to delineate effluent migration from the river-to-aquifer and from the aquifer-to- river. U.S.G.S. developed MODFLOW which is a reliable numerical ground water model. DEP used MODFLOW to simulate water levels and to depict hydraulic conditions in the subject area. In the instant case, DEP first examined available data such as water levels, rainfall, and hydraulic conductivity, to develop a conceptual model. The conceptual model determines the size of the model and presents a hypothesis regarding how the area of interest will operate. The development of the conceptual model includes the determination of boundary conditions. Boundary conditions are mathematical instructions which the modeler uses to simplify the model. They reflect the conditions at the geographical limits of the model. DEP used "no-flow" boundary conditions for the north, east and south boundaries. These conditions represent areas where water outside the boundaries flows away from the model. DEP used a "constant head" boundary condition for the western boundary of the model, i.e. a determination that the ground water level does not fluctuate substantially in that area. In developing the conceptual model, DEP also considered relative recharge throughout the area, relative hydraulic conductivity, and drainage conditions. "Calibration" refers to a process where a modeler adjusts factors within the model to minimize the difference between measured water levels and simulated water levels. DEP initially calibrated the MODFLOW model to simulate hydrologic conditions on May 11, 1994. Next, DEP calibrated the MODFLOW model to simulate hydrologic conditions on April 25, 1989 which represents a worst case scenario for a dry season in the study area. U.S.G.S. also developed MODPATH. It is a computer model which uses MODFLOW head (water level) data to simulate the direction of ground water flow. The software simulates where a particle of water would flow based on head data provided by the MODFLOW model. In this case, the MODPATH model yielded a conservative projection of areas where ground water could be impacted by water from the Fenholloway River in a worst case dry season scenario. DEP used a flood season map to delineate the worst case flood season scenario. Historical data indicates that the worst surface river flood on record was Hurricane Dora on September 10 - 13, 1964. DEP used a U.S.G.S. flood prone area map to show the extent of river flooding during Hurricane Dora. DEP conservatively assumed that river flood waters could affect the ground water in the area flooded by the river during this storm. The flood prone map shows areas of inundation flooding from the river and areas of drainage flooding experienced during Hurricane Dora in 1964. The term inundation flooding refers to water that has been in the river which is transported to a certain distance as it floods out of the river banks. The term drainage flooding refers to rainfall which accumulates in a depressed area. Drainage flooding is influenced by the intensity and duration of rainfall and the slope of the depressed area. Since 1955 the U.S.G.S has compiled river water level data in the subject area. Hurricane Dora represents a conservative worst case scenario for a wet season or flood because the water levels resulting from that storm were higher than the levels at any other time in recorded history. Areas outside of the delineated corridor may be flooded from time to time. However, they represent isolated wetlands which are not connected to the Fenholloway River. Therefore, there is no need to include them in the corridor of potentially impacted areas. The corridor in DEP's 1995 Report includes: (a) the entire river flood plain inundated by Hurricane Dora during the worst case flood scenario; (b) the potential extent of river influence during the worst case dry season scenario; and (c) all areas where simulated particles in the steady-state simulation flow computer model computer model migrated from river to ground water, including areas of very low potential. DEP based the computer modeling in the 1995 Report on reliable data from historical records and from the network of monitoring wells in the study area. DEP had sufficient data from the monitoring wells to develop valid ground water elevation maps in the study area for the computer modeling. U.S.G.S. topographic maps are reliable as to elevation numbers. They are commonly relied upon by geologist to determine the direction of surface water flow. U.S.G.S. flood prone area maps depict areas that are impacted by river inundation and are commonly relied upon by geologists. DEP geologists reasonably relied upon the U.S.G.S. flood prone area map of the river. U.S.G.S. river elevation recording station data (from bridges at U.S. 27, U.S. 19 and Route 356 near Hampton Springs) are commonly relied upon by geologist. DEP used proper methods to determine how river water moves during flood conditions. DEP properly excluded from consideration areas that were flooded during Hurricane Dora by local rainfall as opposed to river water. The corridor identified by the 1995 Report correctly reflects a conservative depiction of an area where the river water could influence the ground water in the worst case dry season scenarios, both actual and simulated; it also conservatively depicts the area where the river water could influence surface and ground waters in the worst case flood scenario. The 1995 Report appropriately concluded that there was no potential for areas beyond the defined corridor to be impacted by the industrial waste discharged into the river. Mr. Cutter's property is located within the study area of the 1995 Report but outside the corridor delineated in the report. His property is about one mile from the edge of the 1964 worst case scenario river flood plain. It is situated close to monitoring well number PM02. State agencies have tested Mr. Cutter's well water on several occasions. They have never found any violations of drinking water standards or any exceedances of health advisory levels. Based on the steady-state simulated computer model, river water will not impact Mr. Cutter's property during a dry season worst case scenario. During dry seasons, it is not possible for river water to migrate 8000 feet to Mr. Cutter's land because ground water in the shallow aquifer on the south side of the river is moving from higher to lower elevations toward the river. Consequently, there is no potential for Mr. Cutter's land to be affected by river water during a dry season. River water did not effect Mr. Cutter's property during the 1964 worst case flood scenario, as revealed by the recorded extent of river flooding and the elevation of his land. During Hurricane Dora, the flood elevation of the river was 25 feet above sea level at the nearest point to Mr. Cutter's land which is at least 27-28 feet above sea level. The differences in these elevations makes it impossible for river water to Mr. Cutter's land during the worst case flood scenario. During the 1984 storm, Mr. Cutter's land was about 7-8 feet higher than the recorded maximum river flood waters. The greater weight of the evidence indicates that any flooding on Mr. Cutter's land at that time was the result of drainage or rainfall flooding and not the result of inundation from the Fenholloway River. In the 1994 storm, Mr. Cutter drove from Waldo Springs near the river to his home through less than 18 inches of water. The water was deep enough to reach the floorboard of his vehicle. Mr. Cutter acknowledges that if the topographic maps relied upon by DEP are correct, he would have driven through five feet of water in order for flood water from the river to have reached his land. He stated that the water at his house or in the area between his house and the river was not five feet deep. There are isolated sloughs in the area of Mr. Cutter's land. However, there are no sloughs that continuously extend from the river to Mr. Cutter's property. Therefore, flood water from the river cannot reach Mr. Cutter's land by running through sloughs. Natural conditions, including the decay of organic matter, can cause surface and ground water discoloration. If a well is located near a slough or wetlands, percolation from the slough or wetlands can result in brown well water. There is no persuasive evidence that the discoloration of Mr. Cutter's well water is the result of contaminated river water. The high ground water elevations between Waldo Springs and Mr. Cutter's property act as a barrier to any ground water movement to the southwest in the direction of Mr. Cutter's property. One resident witness testified that his well was contaminated by ethyl dibromide (EDB), a pesticide with no link to river water or kraft pulp mill effluent. EDB is a nematicide commonly used in crops such as citrus and soybeans. It is also used in turf management for golf courses and landscaping projects. Buckeye's mill in Foley, Florida produces fluff wood pulp that is used in products like diapers. It also produces special dissolving wood pulps that are used by the filter industry (including air and oil filters) and the filament industry (including rayon clothing and specialty rayon products used in tire cords). In the kraft pulp mill process, the mill withdraws about 47-50 million gallons per day (MGD) of ground water from the wellfield and discharges about 50 MGD of treated effluent from an aeration pond into the river. The mill has a sewer system that captures the effluent from the manufacturing process. It also has about 150 acres of aerated treatment lagoons. During the time that DEP was studying the issue that resulted in the 1995 Report, Buckeye spent about $2 million providing free bottled water to Taylor County residents and paying the City of Perry to run water lines to homes of people who complained about their well water. Buckeye has a monitoring network of wells around the mill. It maintains liners under its lagoons. Buckeye's interest in this proceeding is: (a) to ensure that it can continue to discharge under its permits from DEP; and (b) to support the 1995 Report of DEP even though Buckeye takes the position that the corridor in that report should be narrower. Buckeye has provided a sufficient basis to support its status as intervenor.

Findings Of Fact The Petitioner, Bocilla Waterways, Inc., is a corporate entity formed for the purpose of pursuing the subject project and installing the proposed channel. Randall Craig Noden, secretary- treasurer of that corporation, and a director of it, is a realtor who sells and develops property on Don Pedro Island, in the vicinity of the proposed project. He and other officers and directors of the Petitioner corporation have an interest in property on some, but not all, upland areas adjacent to Bocilla Lagoon, Old Bocilla Pass and Kettle Harbor, the water bodies germane to this proceeding. The Respondent, State of Florida, Department of Environmental Regulation, is a state agency charged with regulating dredge and fill projects in state waters and navigable waters pursuant to Chapters 253 and 403, Florida Statutes, and Rule Chapters 17-3 and 17-4, Florida Administrative Code. The Intervenor, Environmental Confederation of Southwest Florida (ECOSWF), is an incorporated, not-for-profit organization whose membership includes numerous environmentally concerned public interest organizations or associations located throughout southwest Florida. Members of the Intervenor use Old Bocilla Pass, Kettle Harbor, Bocilla Lagoon and Lemon Bay, an adjacent contiguous water body, for boating, swimming, fishing (both recreational and commercial), and collecting shellfish. Some of the membership of the Intervenor live in the immediate area of the proposed project. Project Description The Petitioner submitted a dredge and fill permit application to the Respondent, DER, proposing excavation of an access channel through the uplands of Don Pedro Island and adjacent transitional and submerged lands. The channel would be 100 feet wide, 450 feet long and dredged to a depth of -5.0 feet mean low water, with 2:1 side slopes grading to 3:1 at approximately +0.5 feet NGVD. The channel below mean high water would be 70 feet wide' and 670 feet long to a depth of -5.0 feet mean low water, with 2:1 side slopes. A rip-rap strip five feet wide would be placed in the littoral zone on either side of the channel. As originally proposed, the channel excavation would be performed by dragline and clamshell with spoil placed upon uplands for disposal. The excavation would progress from the west side of the project to the east, with plugs remaining at the eastern terminus of the channel until it stabilizes and the rip- rap is placed along the excavated channel. A turbidity curtain is proposed to be used to maintain water quality above state standards regarding turbidity. The applicant originally proposed to transplant seagrasses, displaced in the excavation process, back into the bottom of the excavated channel. Earthen slopes above mean high water would be vegetated in order to achieve stabilization. Some of these proposals were modified after negotiations with DER staff, such that the seagrass transplanting portion of the project would be accomplished in surrounding areas of the water bottom of Bocilla Lagoon and Kettle Harbor, specifically, bare areas and otherwise degrassed, vegetated flats. The applicant also proposes to install navigation aides in Bocilla Lagoon and Kettle Harbor in order to help maintain boat traffic in the channel, and to facilitate ingress and egress through the proposed channel. Don Pedro Island is a barrier island lying off the coast of Charlotte County, Florida. The only access to the island is by boat or helicopter. Bocilla proposes to excavate the proposed channel in order to, in part, provide better navigational access to Bocilla Lagoon which lies within Don Pedro Island. There is presently a navigational channel in the Bocilla Lagoon through what is called "Old Bocilla Pass," located at the north end of Bocilla Lagoon and communicating with Lemon Bay. Bocilla contends that the channel is somewhat tortuous and subject to shoaling, with concomitant grassbed damage by boat propellers, and that thus, a better navigational access in the form of a shorter, deeper, more direct channel from the southern end of Bocilla Lagoon to Kettle Harbor is required. The project would involve the removal of approximately .18 acres of mangroves (red and black mangroves) and .187 acres of seagrasses. Bocilla has proposed to mitigate the damage involved in the mangrove and seagrass removal by replanting mangroves, on three foot centers, along both sides of the proposed channel, and replanting or transplanting seagrasses in bare areas of Kettle Harbor, near the proposed project. Description of Pertinent State Waters Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass are designated as Class II, navigable waters of the state and are designated for shellfish propagation or harvesting. Shellfish, including clams and oysters, occur in Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass. As demonstrated by Intervenor's witnesses Wade, Cole and Wysocki, shellfish are harvestable and harvested in Bocilla Lagoon and Kettle Harbor at the present time. Bocilla Lagoon, Kettle Harbor and Old Bocilla Pass have also been conditionally approved by DNR for shellfish harvesting. DNR approves or prohibits waters for shellfish harvesting, and as a matter of policy generally prohibits shellfish harvesting in manmade "dead-end" canals. A "conditionally approved" water body, such as those involved herein, is an area approved for shellfish harvesting, but one which is more likely to be affected by pollution events. Thus, they are monitored more closely by DNR. Such events as additional residential development in an area, resulting in more septic tank sewage discharge, on-board toilet discharges from boats or the installation of a water and sewer treatment plant, can result in DNR temporarily or permanently closing a conditionally approved area to shellfish harvesting. Natural phenomenon such as the influx of red tide is also a factor which is considered by DNR in electing to classify a shellfish harvesting area as conditionally approved, and in electing to prohibit shellfish harvesting in an area. It was established through testimony of witnesses Feinstein and Setchfield of DER that long-standing DER policy provides that when DNR conditionally approves waters as being shellfish harvestable, that means they are "approved" for all shellfish harvesting purposes, but simply subjected to closer monitoring and with an increased likelihood of closure due to immediate pollution events. Therefore, the prohibition in Rule 17- 4.28(8)(a), Florida Administrative Code, prohibits issuance of dredge and fill permits in areas approved for shellfish harvesting or "conditionally" approved, since there is no difference in the "shellfish harvestable" nature of the waters until a closure occurs, which may simply occur sooner in conditionally approved waters. Bocilla Lagoon and Kettle Harbor are both naturally- formed water bodies, although some dredging has been allowed to occur in them in the past. They are not manmade, "dead-end" canals. Neither water body has the physical or biological characteristics of a "typical dead-end canal". Both are quite high quality habitats for the natural flora and fauna occurring in the marine environment in that area, and thus the general policy of DNR established by witnesses Cantrell, Fry, Feinstein and Sperling which prohibits shellfish harvesting in manmade, dead-end canals, does not apply to Bocilla Lagoon and Kettle Harbor. The water quality in both bodies of water is good and within DER standards generally. At times however, the water quality in Kettle Harbor suffers from a failure to meet DER dissolved oxygen standards contained in Chapter 17-3, Florida Administrative Code. Indeed, the water quality in Bocilla Lagoon is generally somewhat better than the water quality in Kettle Harbor. Environmental Impacts The project as currently proposed would result in the removal of approximately .18 acres of mangroves and .18 acres of seagrasses. Seagrasses and mangroves are important in providing areas of cover, food, and habitat for various estuarine species. Seagrasses serve to stabilize marine soils resulting in a decrease of suspended solids in contiguous waters with resulting decrease in turbidity in those waters. The loss of seagrasses can result in de- stabilization of the bottom sediment, such that suspended solids or turbidity increases in involved waters, which can result in decreased light penetration to the vegetated bottoms. Decreased light penetration, if of a sufficient degree, can result in the further loss of seagrasses and other bottom flora, causing in turn, increased turbidity and further decreased light penetration, with progressively destructive results to seagrass beds and other marine flora and fauna, with a substantial detrimental effect on the marine biological community in general. Mangroves serve as biological filters, trapping sediments, heavy metals, nutrients and other pollutants, uptaking them through their roots and converting them to usable plant food and thus filtering such harmful elements from state waters and rendering them into environmentally harmless substances. The removal of the mangroves at the proposed channel site will result in a loss of their beneficial effects. These beneficial effects will be absent for a greater period of time than it takes to merely plant replacement mangrove plants, since mature trees will be removed and mangrove seedlings will be replanted in their stead. Maturation of mangroves at this location would take in excess of three years, thus replacement of the beneficial filtering effects of the removed mangroves will take in excess of three years, to which time must be added the time which lapses between the original mangrove removal and the replanting of the seedlings, which would start the maturation period. Bocilla proposes to mitigate the removal of the mangroves by that replanting, as well as to transplant seagrasses removed from the channel site to other nearby areas currently bare of seagrass. Seagrass replanting is not a well-established practice. Compared to mangrove replanting, there is less experience, less information and a lower success ratio historically. Of the hundreds of dredge and fill projects occurring and approved throughout Florida, only three have involved replanting of removed seagrasses. Two of the projects involved the Port of Miami in Dade County and the "New Pass site" in Sarasota County. In both of these cases, seagrass replanting cannot be termed successful. The Port of Miami project resulted in a final survival rate of only twelve per cent of ,the grasses replanted. The New Pass project thus far has resulted in a survival rate of only 39 per cent of the seagrasses replanted, after only nine months. The Petitioner proposes that the replanting be accomplished by Mangrove Systems, Inc. That firm is headed by Robin Lewis, who oversaw the seagrass replanting project at the New Pass area in Sarasota. The location and method of replanting seagrasses at New Pass, as to water depth, type of bottom, type of grass and planting method, was generally similar to that proposed for the Bocilla project. That is, it would be accomplished by "plug planting," of "bald" spots at generally the same latitude and similar water depth. The survival rate at the end of six months at the New Pass project was 73 per cent. The survival rate at the end of nine months was 39 per cent. Mangrove Systems, Inc. and Mr. Lewis acknowledges that it is difficult to attribute the decrease in survival rates and grass shoot densities to any one cause, but that predation and a shift in sediments due to the vagaries of water currents, were probably the chief causes for the decrease in seagrass survival. Mangrove Systems, Inc. and the Petitioner propose a guarantee whereby Mangrove Systems, Inc. would replant more seagrasses, if needed, if a low survival rate occurs, which it defines to mean less than a 70 to 80 per cent survival rate after one or two years. There is no guarantee concerning the survival rate after a second planting, however. It was not established when the survival rate will be measured, in determining whether a 70 to 80 per cent survival is being achieved. In this connection, the central Florida coast where the Bocilla project is proposed, is not as conducive to seagrass growth as other more tropical marine areas, such as in the Florida Keys. In the area of the proposed project, seagrasses do not generally produce a great deal of seed and tend not to grow back very readily, once they are destroyed. Seagrasses in the Florida Keys tend to have, in comparison, much greater seed production and for this and other reasons, tend to reproduce themselves more readily once destroyed. They tend to be more amenable to transplanting in the Florida Keys marine environment. Mangrove Systems, Inc. has conducted a seagrass replanting project in the Florida Keys, however. One-third of the seagrasses planted in that project have not survived after two years. In short, the likelihood of seagrass survival has been insufficiently tested in the geographical area and latitude and in similar soils, water depths and temperatures as those involved in the instant case, such that reasonable assurance of adequate seagrass survival with the replanting project proposed will occur. Hydrographics and Maintenance Dredging The evidence is uncontradicted that the opening of the proposed channel would increase circulation in the southern end of Bocilla Lagoon. Increased circulation tends to have good effects in that it reduces stratification in water bodies. Stratification is a condition which occurs when the deeper waters of a given water body do not interchange with surface waters, but rather stratify or become characterized by layers of differing levels of dissolved oxygen, temperature, pH, etc. Typically, lower levels of a stratified body of water are characterized by low levels of dissolved oxygen. The present water quality of Bocilla Lagoon however, is not characterized by statification in any significant degree. It is very similar in water quality, in terms of dissolved oxygen, temperature, pH and other Chapter 17-3 water criteria, to that water quality of the nearby intra-coastal waterway into which the channel into and through Kettle Harbor would open. The intra-coastal waterway is agreed to be a well- circulated body of water, meeting all current State water quality standards. Accordingly, the opening of the channel and the increased circulation it may cause in the southern end of Bocilla Lagoon would have minimal, positive benefits. The change in circulation and in water current patterns and velocities caused by the opening of the direct, shorter channel from lower Bocilla Lagoon and Kettle Harbor may, negatively affect the present seagrass growth in seagrass beds in Kettle Harbor and Bocilla Lagoon in the vicinity of each end of the proposed channel, due in part to increased current velocities that would result from tidal exchange through the shorter, straight channel which would be opened. The expert witnesses in the area of hydrographics disagreed on the effect of the proposed channel on water circulation in the northern end of Bocilla Lagoon and Old Bocilla Pass, which is the north channel opening into northern Bocilla Lagoon. Witness Sperling for the Department opined that a major reduction in flows through Old Bocilla Pass channel would occur. Witness Tackney for the Petitioner acknowledged there would be some reduction in flow, and witness Olsen opined that a reduction in flow would occur, but there could also be an increase in circulation. Both witnesses Tackney and Olsen, in opining that a flow-through, enhanced circulation and flushing system may result from installing the channel, based that opinion to a significant degree, on their belief on the effects of wind on forcing water through the Pass and Bocilla Lagoon. No wind data or records were adduced however, to show the likely effects of wind on creating the Petitioner's desired "flow-through" system. Witness Sperling disagreed as to the significance of this flow-through effect, but there was no disagreement among the hydrographic experts that reduced flows through Old Bocilla Pass, which all acknowledged can occur to one degree or another, can result in increased sedimentation in Old Bocilla Pass, which can result in turn, in the need for increased maintenance dredging in Bocilla Lagoon and Old Bocilla Pass in the future. Maintenance dredging in Old Bocilla Pass may have to be increased if the proposed channel is constructed. The proposed channel itself will likely have to be periodically maintenance dredged as well. Maintenance dredging can cause environmental problems. Dredging activities result in the loss of marine habitat and the destabilization of marine sediments, with resulting increased turbidity and reduced photic effects, with concomitant detrimental effects on seagrasses and other bottom flora and fauna. Increased turbidity resulting from dredging and destabilization of sediments can directly adversely affect shellfish, including clams and oysters. Dredging impacts and siltation can negatively affect seagrass growth and water quality by increasing turbidity resulting in reduced photosynthesis in seagrass, by smothering the seagrass directly and by silting fauna and vegetation in adjacent productive grassbeds. Persons other than the officers and directors of Bocilla Waterways, Inc. own property and have riparian rights on the Old Bocilla Pass channel. These persons have in the past, and have the right in the future, to use Old Bocilla Pass for navigational purposes and could elect to maintenance dredge Old Bocilla Pass as they have in the past. If the proposed channel is constructed, there is obviously a more direct access and shorter water route between the waters of Bocilla Lagoon and Kettle Harbor. Water quality at times in Kettle Harbor has been worse than that in Bocilla Lagoon, especially in terms of low dissolved oxygen. If poorer water quality exists in Kettle Harbor due to low dissolved oxygen, an influx of red tide or some other cause, the construction of the proposed channel would increase the chance, by the more direct connection and increased flow in the southern end of Bocilla Lagoon, to contaminate the water of Bocilla Lagoon. The Public Interest Public opposition was expressed at the hearing, including that of ECOSWF, the Intervenor, some of whose members include people who live in the area of the proposed channel and use the involved waters. Local fishermen who harvest shellfish and finfish in Bocilla-Lagoon and Kettle Harbor, and use Old Bocilla Pass for navigation between Lemon Bay and Bocilla Lagoon, oppose the project, some of whom are members of the organized Fishermen of Florida, an association of approximately 25,000 members. Residents of Bocilla Lagoon and the immediate area, who habitually navigate Old Bocilla Pass, including local fishermen, have had little trouble navigating Old Bocilla Pass because they are familiar with the channel. Although the Petitioner alleges that the new channel is needed in part for the safety of people living on Bocilla Lagoon to assure quick access to the mainland in case of medical emergencies, the members of the public living on Bocilla Lagoon, (with one exception) and on surrounding areas of the island, do not wish such increased access for medical purposes. The island is presently reached from the mainland by either watercraft or helicopter. Formerly, there was a bridge connecting the island with the mainland which has since been destroyed, and not rebuilt. The residents living on Bocilla Lagoon, either full- time or part-time, buy their homes and choose to live there with knowledge of the present mode of access through Old Bocilla Pass, which is also the means they would achieve access to the mainland in case of medical emergencies or, alternatively, by helicopter transport or by transport over island roads to the ferry landing, with access to the mainland by ferry. The residents, in general, desire to maintain the isolation of life on the island as it presently exists and do not desire enhanced access between the island and the mainland, since part of the charm of having homes and living on the island is its isolation from the more populous mainland. Other than the testimony of Petitioner's witnesses, there was no testimony presented expressing any public need for the proposed channel, as for instance from public officials having knowledge of any medical or public health need for enhanced access to Bocilla Lagoon and the island. The proposed project is contrary to the public interest due to its adverse effects on seagrasses, shellfish, and water quality as delineated above. The adverse effects on seagrasses would result from the dredging itself and the destruction of a portion of the extant seagrass beds, and the resultant likelihood of poor survival rates in the attempted transplanting of seagrass as a replacement for that destroyed by the channel dredging. The proposed project is not in the public interest of those people with riparian rights on Old Bocilla Lagoon and northern Bocilla Lagoon, as there is substantial likelihood the proposed project will reduce flows through Old Bocilla Pass' channel with the resultant increased settling out of sediment and thus increased shoaling of that channel, which would concomitantly increase the need for maintenance dredging in Old Bocilla Lagoon and channel. Additional maintenance dredging and the possible negative effects of such additional dredging on marine, flora and fauna in Bocilla Lagoon and Old Bocilla Pass constitute an additional burden on these riparian owners, the bearing of which is not in their interest. The proposed project is also contrary to the public interest in that the proposed channel is deeper, wider and more direct as an entry into Bocilla Lagoon from Kettle Harbor and Lemon Bay, and would thus allow larger, deeper draft boats to enter Bocilla Lagoon with concomitant increased pollution from oils, greases and possible discharge of onboard sewage, which could have adverse environmental impacts on water quality in Bocilla Lagoon, as well as Kettle Harbor. The use of deeper draft, larger boats with larger propellers and more powerful engines could also result in damage to adjacent grassbeds in the vicinity of either ends of the proposed channel, either through direct propeller contact or through prop wash, when such boats are navigated in areas minimally deep enough to accommodate their draft. Since the installation of the proposed channel would result in a deeper, more readily used access to Bocilla Lagoon by larger boats with the remaining original channel usable also, at least for a time, there is a-substantial likelihood of increased residential development on riparian property around Bocilla Lagoon. This could have the result of reducing water quality in the lagoon, or potentially so, through septic tank leachate, stormwater runoff and other adverse environmental effects, such that the water in the lagoon traditionally approved for shellfish harvesting may be prohibited in the future.
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 a Final Order be entered by the Department of Environmental Regulation denying both the variance application and the permit application sought by Bocilla Waterways, Inc.

The Issue Whether the activities conducted on respondent's property required a dredge/fill permit and whether respondent violated the conditions of the permit issued on February 15, 1985.
Findings Of Fact Respondent is the record holder of a parcel of land located within Section 35, Township 45, South, Range 21 East, in Lee County, Florida. Respondent's property is contiguous to Pine Island Sound, a Class II, Outstanding Florida Water. Maureen Powers, an Environmental Specialist with the Department initially inspected respondent's property on May 23, 1984, after the Department received an anonymous complaint that someone was clearing away mangroves on the property. Ms. Powers-discovered that an earthen-fill road had been constructed on the property, and a portion of the road, 24' x 43'; was located within the landward extent of the state's waters. The determination that the portion of the road was within the Department's jurisdiction was based on the dominance of black and white mangroves. There had been recent mangrove cutting in the area, and a pile of vegetative debris, the result of the cutting, had been placed in the jurisdictional wetlands contiguous to Pine Island Sound. On June 1, 1984, Ms. Powers met with respondent in Langley Adair's office to discuss the violations observed on May 23, 1984, and to discuss the resolution of these violations. Respondent agreed to remove all of the earthen fill and vegetative debris that he had deposited within the jurisdictional wetlands. He agreed to refrain from any further work within the jurisdictional area prior to receiving a permit from the department. He also agreed to open up a flow channel in the berm along Pine Island Sound to restore circulation to the area. On July 11, 1984, Ms. Powers conducted an on-site inspection and discovered that the vegetative debris and the fill material had not been removed. Further, it was apparent that respondent's proposed home site, outlined by string and stakes, was submerged and directly connected by water to Pine Island Sound. The water standing on the property covered a portion of the fill area. On August 8, 1984, another inspection was performed, and it was discovered that respondent still had not removed the fill materials. The condition of the property was essentially the same as it had been on July 11, 1984. By letter dated August 20, 1984, respondent was again notified of the violations and reminded that he had agreed on June 1, 1984, to remove the vegetative and earthen fill. Respondent was informed that he needed to remove the fill materials within 30 days of receipt of the letter in order to avoid further enforcement action. On September 5, 1984, Ms. Powers again inspected the property and found that the proposed homesite and a portion of the fill were still submerged, that the water connected directly with Pine Island Sound and the fill materials had not been removed. Also apparent was a flume of milky white water which originated at the toe of the fill and continued into Pine Island Sound. Water samples were taken which revealed that the erosion of the unauthorized fill was resulting in a violation of state surface water quality criteria, specifically, turbidity1 greater than 29 Nephelometric Turbidity Units above natural background. The background sample, taken upstream from the site of the discharge, had a value of 5.2 turbidity units. The water sample taken two feet from the toe of the fill had a value of 69 turbidity units, and the sample from Pine Island Sound waterward of the mangrove fringe had a value of 46 turbidity units. On October 9, 1984, a letter was sent to respondent which pointed out that the earthen and vegetative fill had not been removed and notifying respondent that erosion of the earthen fill into the waters of Pine Island Sound had resulted in violation of surface water quality criteria. Respondent was requested to immediately cease and desist from all unauthorized. activity under the Department's jurisdiction. To clarify the situation, original photos of the site were sent with the letter which showed the earthen fill, the vegetative debris, and the turbid water leaving the site. A diagram of the site was also included to show the location fill materials that were to have been removed. On October 25, 1984, Ms. Powers met with Mr. Decker at the site. Ms. Powers showed respondent the earthen fill and vegetative debris that should have been removed. Ms. Powers noted that the waterward 23' x 24' section of the earthen fill had become heavily colonized by black mangrove seedings and, therefore, excepted that portion of the fill from the removal requirement so that the seedlings would not be disturbed. Mr. Decker stated that he would remove the unauthorized fill within two weeks. Meanwhile, apparently in September, respondent had submitted a permit application. Mr. Beaver was the field inspector assigned by DER to evaluate the application and make a recommendation on the feasibility of the project to the dredge and fill supervisor. On October 8, 1984, Mr. Beaver performed the field inspection at the site, and on October 23, 1984, issued his permit application appraisal recommending that the application be denied. Mr. Beaver recommended that the project be reconsidered for a permit if, among other things, the house site were removed from the landward extent of the state waters and located in the uplands, the septic tank were removed from the low lying portions of the site, and previously cut areas were allowed to regrow in native vegetation. On November 15, 1984, Mr. Beaver met with Mr. Decker and Mr. Cantrell, the district supervisor of dredge and fill, to discuss the project. Mr. Cantrell asked how the project could be modified so that Mr. Decker could have his house in the location where he wanted it. Mr. Beaver suggested a stilt, elevated house with a small fill pad that would allow access to the entrance of the house. The house would have to be elevated -enough so that revegetation of wetland plants could occur underneath the house structure and water flow could be maintained. On November 19, 1984, Ms. Powers and Mr. Beaver met Mr. Decker at the property. Ms. Powers and Mr. Beaver staked the DER jurisdiction line and marked the proposed location of Mr. Decker's boardwalk. Mr. Decker asked about placing wood chip mulch on the wetlands on his property in order to beautify the area. Mr. Decker was informed that wood chip mulch was considered vegetative fill and would require modification of his permit application. Subsequent to the meeting of November 15 and the on- site inspection of November 19, Mr. Decker modified his project. However, wood chip mulch was not mentioned. On December 7, 1984, Mr. Beaver recommended that the application be approved subject to specified conditions, which were ultimately incorporated into the permit. On December 11, 1984, Ms. Powers inspected the site and discovered that a large pile of wood chips had been placed on the northeast end of the fill road waterward of the jurisdiction line. The vegetative debris and earthen fill that had previously been on the project had not been removed. Respondent was notified of the violations by a Cease and Desist letter dated January 4, 1985. The letter pointed out that respondent had been told specifically that wood chip mulch was considered vegetative fill and that dredge/fill permit would be required prior to the placement of any fill material. On February 5, 1984, respondent met with DER, officials to discuss the violations. Mr. Decker stated that the fill had been removed as requested. The Department informed Mr. Decker that an inspection would be performed and, if the fill had not been removed, the Department would pursue formal enforcement action. On February 7, 1985, the site was inspected none of the fill material had been removed. A subsequent inspection on February 20, 1985, revealed that the wood chips had been spread throughout the jurisdictional wetlands. On February 15, 1985, respondent received a permit to fill and to construct a dock and boardwalk. The specific conditions of the permit include the following: 2. A 20' x 16' - 4" fill pad shall be the only fill placed waterward of the jurisdictional line. This fill pad will be composed of clean sand and have the banks stabilized by a riprap revetment with a slope not greater than 2H:1V. * * * The house and all associated structures shall be built upon stilts with concrete footings and/or wooden pilings. On-site turbidity control devices shall be installed and properly maintained to localize turbidity impacts to the construction area. * * * All vegetative debris, trash and spoil material resulting from concrete footing placement shall be removed from the landward extent of State Waters as defined by the jurisdiction line staked by the DER. Upon completion of construction, non- filled areas beneath the stilt house and associated structures shall be returned to original grade if they were altered by construction. Wetland vegetation shall be planted in the previously cleared area and mangroves removed by construction activities shall be replaced on a 2 for 1 basis with 80% survival over a three year period. * * * 11. The project shall comply with applicable State Water Quality Standards, namely: 17-3.051 - Minimum Criteria for All Waters at All Times and All Places. 17-3.061 - Surface Waters: General Criteria 17-3.111 - Criteria - Class II Waters Shellfish Propagation or Harvesting, Surface Waters General Conditions 2 and 5 of the permit provide: 2. This permit is valid only for the specific processes and operation applied for and indicated in the approved drawings or exhibits. Any unauthorized deviation from the approved drawings, exhibits, specifications, or conditions of this permit may constitute grounds for 81' filled area was located within the landward extent of the state waters. 19. Respondent has violated several conditions of the permit issued February 15, 1985. Specific Condition #2 provided that the 20' x 16' fill pad would be "the only fill placed waterward of the jurisdictional line." Instead, respondent filled an area approximately 78' x 81' to an average height of about 2\', totaling approximately 585 cubic yards of fill. The fill was non-native fill brought onto the site. The permit did not authorize fill for a septic tank in the revocation and enforcement action by the department. 5. This permit does not relieve the permittee from liability for harm or injury to human health or welfare, animal, plant or aquatic life or property and penalties therefor caused by the construction or operation of this permitted source, nor does it allow the permittee to cause pollution in contravention of Florida Statutes and department rules, unless specifically authorized by an order from the department. On March 19, 1985, an inspection of the property revealed that Mr. Decker had totally ignored the conditions of his permit. Rather than a fill pad of 20' x 16', respondent had filled an area approximately 78' x 81'.2 The fill was unstabilized, and no turbidity control devices were in place. Fill material had been used to construct a earthen berm across a natural flow channel, blocking the flow of water onto the property. Further, the vegetative debris resulting from the construction of the boardwalk had been deposited in the mangrove wetlands. On March 22, 1985, a Notice of Violation and. Orders for Corrective Action was sent to the respondent. Respondent received the notice on or about March 26, 1985. The landward extent of the state waters on respondent's property, the area in which a DER permit is required for dredging and filing, was determined by the presence of red mangroves (Rhizophora mangle), black mangroves (Avicennia germinans), and saltwort (Basis maritime) as the dominant species. The jurisdiction line was originally staked on November 19, 1984, and was reestablished on April 23, 1985, from remaining landmarks, due to the original markers being removed. The 78' x81' filled area was located within the landward extent of the state waters. Respondent has violated several conditions of the permit issued February 15, 1985. Specific Condition #2 provided that the 20' x 16' fill pad would be "the only fill placed waterward of the jurisdictional line." Instead, respondent filled an area approximately 78' x 81' to an average height of about 21/2', totaling approximately 585 cubic yards of fill. The fill was non-native fill brought onto the site. The permit did not authorize fill for a septic tank in the jurisdictional wetlands, but respondent placed a septic tank and drainfield in that area.3 By filling an area several times the size of the area authorized, respondent has seriously violated the conditions of the permit. A fill area of the size that now exists eliminates the habitat and water quality functions that the area historically performed. Respondent has violated Specific Condition #4, which required that the house and associated structures be built on stilts. The purpose of such a requirement is to preserve undisturbed the existing substrate, which constitutes the base of the food chain, and to allow for a free flow of water across the site, which is essential to the health of the mangrove system. Respondent not only filled an area larger than his proposed house, he poured a solid, continuous, concrete foundation on top of the fill, which would prevent the flow of water should the water rise high enough to come onto the filled area.4 By filling the area, destroying the substrate, and preventing the flow of water into the area, respondent has violated Specific Condition #4 of the permit. Respondent violated Specific Condition #5 of his permit in that respondent failed to install any turbidity control devices. Turbidity control devices of some sort are necessary in a fill area such as the one in this case. Turbidity screens or staked hay bales could have been used. Respondent also violated Specific Condition #8. Construction debris and vegetative debris were located throughout the area. Although respondent technically has not violated Specific Condition #9, in that it requires acts to be performed "upon completion of construction", respondent has made compliance with that provision an impossibility because he has filled the "non- filled areas beneath the stilt house" and therefore there are no "non-filled areas" to return to original grade. Respondent has never requested that his permit conditions and requirements be modified. By his actions, respondent has repeatedly shown a complete disregard for the requirements of the law, and he has totally ignored the conditions set forth in the permit. Mr. Decker was not qualified as an expert and I did not find him to be a credible witness. The reasonable costs and expenses incurred by the Department in relation to the enforcement aspects of this action are $866.17. These costs and expenses were incurred by the Department in its effort to control and abate pollutants and to restore the waters and property of the state to their former condition.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the respondent's permit, number 360902245, be revoked that the respondent be ordered to make payment to the Department in the amount of $866.17 for costs and expenses incurred by the state and that the following corrective action be ordered: Respondent shall within thirty (30) days, remove all unauthorized fill material placed within the area of Department jurisdiction. Prior to initiating the fill removal respondent shall arrange for Department personnel to stake the area to be restored. All areas shall be restored to the elevation and soil conditions which existed prior to the placement of fill material. Respondent shall take all necessary precautions to ensure that state water quality standards are not violated during the restoration work. Respondent shall not disturb adjacent areas within the jurisdiction of the Department unless approved by the Department in writing. DONE and ENTERED this a 24th day of January, 1986, in Tallahassee, Leon County, Florida. DIANE A. GRUBBS 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 24th day of January, 1986.
The Issue The issue to be determined is whether Consumptive Use Permit No. 2-083-91926-3, and Environmental Resource Permit No. IND-083-130588-4 should be issued as proposed in the respective proposed agency actions issued by the St. Johns River Water Management District.
Findings Of Fact The Parties Sierra Club, Inc., is a national organization, the mission of which is to explore, enjoy, and advocate for the environment. A substantial number of Sierra Club’s 28,000 Florida members utilize the Silver River, Silver Springs, the Ocklawaha River, and the St. Johns River for water-based recreational activities, which uses include kayaking, swimming, fishing, boating, canoeing, nature photography, and bird watching. St. Johns Riverkeeper, Inc., is one of 280 members of the worldwide Waterkeepers Alliance. Its mission is to protect, restore, and promote healthy waters of the St. Johns River, its tributaries, springs, and wetlands -- including Silver Springs, the Silver River, and the Ocklawaha River -- through citizen- based advocacy. A substantial number of St. Johns Riverkeeper’s more than 1,000 members use and enjoy the St. Johns River, the Silver River, Silver Springs, and the Ocklawaha River for boating, fishing, wildlife observation, and other water-based recreational activities. Karen Ahlers is a native of Putnam County, Florida, and lives approximately 15 miles from the Applicant’s property on which the permitted uses will be conducted. Ms. Ahlers currently uses the Ocklawaha River for canoeing, kayaking, and swimming, and enjoys birding and nature photography on and around the Silver River. Over the years, Ms. Ahlers has advocated for the restoration and protection of the Ocklawaha River, as an individual and as a past-president of the Putnam County Environmental Council. Jeri Baldwin lives on a parcel of property in the northeast corner of Marion County, approximately one mile from the Applicant’s property on which the permitted uses will be conducted. Ms. Baldwin, who was raised in the area, and whose family and she used the resources extensively in earlier years, currently uses the Ocklawaha River for boating. Florida Defenders of the Environment (FDE) is a Florida corporation, the mission of which is to conserve and protect and restore Florida's natural resources and to conduct environmental education projects. A substantial number of FDE’s 186 members, of which 29 reside in Marion County, Florida, use and enjoy Silver Springs, the Silver River, and the Ocklawaha Aquatic Preserve, and their associated watersheds in their educational and outreach activities, as well as for various recreational activities including boating, fishing, wildlife observation, and other water-based recreational activities. Sleepy Creek Lands, LLC (Sleepy Creek or Applicant), is an entity registered with the Florida Department of State to do business in the state of Florida. Sleepy Creek owns approximately 21,000 acres of land in Marion County, Florida, which includes the East Tract and the North Tract on which the activities authorized by the permits are proposed. St. Johns River Water Management District (SJRWMD or District) is a water-management district created by section 373.069(1). It has the responsibility to conserve, protect, manage, and control the water resources within its geographic boundaries. See § 373.069(2)(a), Fla. Stat. The Consumptive Use Permit The CUP is a modification and consolidation of two existing CUP permits, CUP No. 2-083-3011-7 and CUP No. 2-083- 91926-2, which authorize the withdrawal of 1.46 mgd from wells located on the East Tract. Although the existing CUP permits authorize an allocation of 1.46 mgd, actual use has historically been far less, and rarely exceeded 0.3 mgd. The proposed CUP modification will convert the authorized use of water from irrigation of 1,010 acres of sod grass on the East Tract, to supplemental irrigation of improved pasture for grass and other forage crops (approximately 97 percent of the proposed withdrawals) and cattle watering (approximately three percent of the proposed withdrawals) on the North Tract and the East Tract. An additional very small amount will be used in conjunction with the application of agricultural chemicals. CUP No. 2-083-3011-7 is due to expire in 2021. CUP No. 2-083-91926-2 is due to expire in 2024. In addition to the consolidation of the withdrawals into a single permit, the proposed agency action would extend the term of the consolidated permit to 20 years from issuance, with the submission of a compliance report due 10 years from issuance. Sleepy Creek calculated a water demand of 2.569 mgd for the production of grasses and forage crops necessary to meet the needs for grass-fed beef production, based on the expected demand in a 2-in-10 drought year. That calculation is consistent with that established in CUP Applicant’s Handbook (CUP A.H.) section 12.5.1. The calculated amount exceeds the authorized average allocation of 1.46 mgd. Mr. Jenkins testified as to the District’s understanding that the requested amount would be sufficient, since the proposed use was a “scaleable-type project,” with adjustments to cattle numbers made as necessary to meet the availability of feed. Regardless of demand, the proposed permit establishes the enforceable withdrawal limits applicable to the property. With regard to the East Tract, the proposed agency action reduces the existing 1.46 mgd allocation for that tract to a maximum allocation of 0.464 mgd, and authorizes the irrigation of 611 acres of pasture grass using existing extraction wells and six existing pivots. With regard to the North Tract, the proposed agency action authorizes the irrigation of 1,620 acres of pasture and forage grain crops using 15 center pivot systems. Extraction wells to serve the North Tract pivots will be constructed on the North Tract. The proposed North Tract withdrawal wells are further from Silver Springs than the current withdrawal locations. The proposed CUP allows Sleepy Creek to apply the allocated water as it believes to be appropriate to the management of the cattle operation. Although the East Tract is limited to a maximum of 0.464 mgd, there is no limitation on the North Tract. Thus, Sleepy Creek could choose to apply all of the 1.46 mgd on the North Tract. For that reason, the analysis of impacts from the irrigation of the North Tract has generally been based on the full 1.46 mgd allocation being drawn from and applied to the North Tract. The Environmental Resource Permit As initially proposed, the CUP had no elements that would require issuance of an ERP. However, in order to control the potential for increased runoff and nutrient loading resulting from the irrigation of the pastures, Sleepy Creek proposes to construct a stormwater management system to capture runoff from the irrigated pastures, consisting of a series of vegetated upland buffers, retention berms and redistribution swales between the pastures and downgradient wetland features. Because the retention berm and swale system triggered the permitting thresholds in rule 62-330.020(2)(d) (“a total project area of more than one acre”) and rule 62-330.020(2)(e) (“a capability of impounding more than 40 acre-feet of water”), Sleepy Creek was required to obtain an Environmental Resource Permit for its construction. Regional Geologic Features To the west of the North Tract is a geologic feature known as the Ocala Uplift or Ocala Platform, in which the limestone that comprises the Floridan aquifer system exists at or very near the land surface. Karst features, including subterranean conduits and voids that can manifest at the land surface as sinkholes, are common in the Ocala Uplift due in large part to the lack of consolidated or confining material overlaying the limestone. Water falling on the surface of such areas tends to infiltrate rapidly through the soil into the Floridan aquifer, occasionally through direct connections such as sinkholes. The lack of confinement in the Ocala Uplift results in few if any surface-water features such as wetlands, creeks, and streams. As one moves east from the Ocala Uplift, a geologic feature known as the Cody Escarpment becomes more prominent. In the Cody Escarpment, the limestone becomes increasingly overlain by sands, shell, silt, clays, and other less permeable sediments of the Hawthorn Group. The North Tract and the East Tract lie to the east of the point at which the Cody Escarpment becomes apparent. As a result, water tends to flow overland to wetlands and other surface water features. The Property The North and East Tracts are located in northern Marion County near the community of Fort McCoy. East Tract Topography and Historic Use The East Tract is located in the Daisy Creek Basin, and includes the headwaters of a small creek that drains directly to the Ocklawaha River. The historic use of the East Tract has been as a cleared 1,010-acre sod farm. The production of sod included irrigation, fertilization, and pest control. Little change in the topography, use, and appearance of the property will be apparent as a result of the permits at issue, but for the addition of grazing cattle. The current CUPs that are subject to modification in this proceeding authorize groundwater withdrawals for irrigation of the East Tract at the rate of 1.46 mgd. Since the proposed agency action has the result of reducing the maximum withdrawal from wells on the East Tract to 0.464 mgd, thus proportionately reducing the proposed impacts, there was little evidence offered to counter Sleepy Creek’s prima facie case that reasonable assurance was provided that the proposed East Tract groundwater withdrawal allocation will meet applicable CUP standards. There are no stormwater management structures to be constructed on the East Tract. Therefore, the ERP permit discussed herein is not applicable to the East Tract. North Tract Topography and Historic Use The North Tract has a generally flat topography, with elevations ranging from 45 feet to 75 feet above sea level. The land elevation is highest at the center of the North Tract, with the land sloping towards the Ocklawaha River to the east, and to several large wet prairie systems to the west. Surface water features on the North Tract include isolated, prairie, and slough-type wetlands on approximately 28 percent of the North Tract, and a network of creeks, streams, and ditches, including the headwaters of Mill Creek, a contributing tributary of the Ocklawaha River. A seasonal high groundwater elevation on the North Tract is estimated at 6 to 14 inches below ground surface. The existence of defined creeks and surface water features supports a finding that the North Tract is underlain by a relatively impermeable confining layer that impedes the flow of water from the surface and the shallow surficial aquifer to the upper Floridan and lower Floridan aquifers. If there was no confining unit, water going onto the surface of the property, either in the form of rain or irrigation water, would percolate unimpeded to the lower aquifers. Areas in the Ocala Uplift to the west of the North Tract, where the confining layer is thinner and discontiguous, contain few streams or runoff features. Historically, the North Tract was used for timber production, with limited pasture and crop lands. At the time the 7,207-acre North Tract was purchased by Sleepy Creek, land use consisted of 4,061 acres of planted pine, 1,998 acres of wetlands, 750 acres of improved pasture, 286 acres of crops, 78 acres of non-forested uplands, 20 acres of native forest, 10 acres of open water, and 4 acres of roads and facilities. Prior to the submission of the CUP and ERP applications, much of the planted pine was harvested, and the land converted to improved pasture. Areas converted to improved pasture include those proposed for irrigation, which have been developed in the circular configuration necessary for future use with center irrigation pivots. As a result of the harvesting of planted pine, and the conversion of about 345 acres of cropland and non-forested uplands to pasture and incidental uses, total acreage in pasture on the North Tract increased from 750 acres to 3,938 acres. Other improvements were constructed on the North Tract, including the cattle processing facility. Aerial photographs suggest that the conversion of the North Tract to improved pasture and infrastructure to support a cattle ranch is substantially complete. The act of converting the North Tract from a property dominated by planted pine to one dominated by improved pasture, and the change in use of the East Tract from sod farm to pasture, were agricultural activities that did not require a permit from the District. As such, there is no impropriety in considering the actual, legal use of the property in its current configuration as the existing use for which baseline conditions are to be measured. Petitioners argue that the baseline conditions should be measured against the use of the property as planted pine plantation, and that Sleepy Creek should not be allowed to “cattle-up” before submitting its permit applications, thereby allowing the baseline to be established as a higher impact use. However, the applicable rules and statutes provide no retrospective time-period for establishing the nature of a parcel of property other than that lawfully existing when the application is made. See West Coast Reg’l Water Supply Auth. v. SW Fla. Water Mgmt. Dist., Case No. 95-1520 et seq., ¶ 301 (Fla. DOAH May 29, 1997; SFWMD ) (“The baseline against which projected impacts conditions [sic] are those conditions, including previously permitted adverse impacts, which existed at the time of the filing of the renewal applications.”). The evidence and testimony in this case focused on the effects of the water allocation on the Floridan aquifer, Silver Springs, and the Silver River, and on the effects of the irrigation on water and nutrient transport from the properties. It was not directed at establishing a violation of chapter 373, the rules of the SJRWMD, or the CUP Applicant’s Handbook with regard to the use and management of the agriculturally-exempt unirrigated pastures, nor did it do so. Soil Types Soils are subject to classifications developed by the Soil Conservation Service based on their hydrologic characteristics, and are grouped into Group A, Group B, Group C, or Group D. Factors applied to determine the appropriate hydrologic soil group on a site-specific basis include depth to seasonal high saturation, the permeability rate of the most restrictive layer within a certain depth, and the depth to any impermeable layers. Group A includes the most well-drained soils, and Group D includes the most poorly-drained soils. Group D soils are those with seasonal high saturation within 24 inches of the soil surface and a higher runoff potential. The primary information used to determine the hydrologic soil groups on the North Tract was the depth to seasonal-high saturation, defined as the highest expected annual elevation of saturation in the soil. Depth to seasonal-high saturation was measured through a series of seven hand-dug and augered soil borings completed at various locations proposed for irrigation across the North Tract. In determining depth to seasonal-high saturation, the extracted soils were examined based on depth, color, texture, and other relevant characteristics. In six of the seven locations at which soil borings were conducted, a restrictive layer was identified within 36 inches of the soil surface. At one location at the northeastern corner of the North Tract, the auger hole ended at a depth of 48 inches -- the length of the auger -- at which depth there was an observable increase in clay content but not a full restrictive layer. However, while the soil assessment was ongoing, a back-hoe was in operation approximately one hundred yards north of the boring location. Observations of that excavation revealed a heavy clay layer at a depth of approximately 5 feet. In each of the locations, the depth to seasonal-high saturation was within 14 inches of the soil surface. Based on the consistent observation of seasonal-high saturation at each of the sampled locations, as well as the flat topography of the property with surface water features, the soils throughout the property, with the exception of a small area in the vicinity of Pivot 6, were determined to be in hydrologic soil Group D. Hydrogeologic Features There are generally five hydrogeologic units underlying the North Tract, those units being the surficial aquifer system, the intermediate confining unit, the upper Floridan aquifer, the middle confining unit, and the lower Floridan aquifer. In areas in which a confining layer is present, water falling on the surface of the land flows over the surface of the land or across the top of the confining layer. A surficial aquifer, with a relatively high perched water table, is created by the confinement and separation of surface waters from the upper strata of the Floridan aquifer. Surface waters are also collected in or conveyed by various surface water features, including perched wetlands, creeks, and streams. The preponderance of the evidence adduced at the final hearing demonstrates that the surficial aquifer exists on the property to a depth of up to 20 feet below the land surface (bls). Beneath the surficial aquifer is an intermediate confining unit of dense clay interspersed with beds of sand and calcareous clays that exists to a depth of up to 100 feet bls. The clay material observed on the North Tract is known as massive or structureless. Such clays are restrictive with very low levels of hydraulic conductivity, and are not conducive to development of preferential flow paths to the surficial or lower aquifers. The intermediate confining unit beneath the North Tract restricts the exchange of groundwater from the surficial aquifer to the upper Floridan aquifer. The upper Floridan aquifer begins at a depth of approximately 100 feet bls, and extends to a depth of approximately 340 feet bls. At about 340 feet bls, the upper Floridan aquifer transitions to the middle confining unit, which consists of finely grained, denser material that separates the interchange of water between the upper Floridan aquifer and the lower Floridan aquifer. Karst Features Karst features form as a result of water moving through rock that comprises the aquifer, primarily limestone, dissolving and forming conduits in the rock. Karst areas present a challenging environment to simulate through modeling. Models assume the subsurface to be a relatively uniform “sand box” through which it is easier to simulate groundwater flow. However, if the subsurface contains conduits, it becomes more difficult to simulate the preferential flows and their effect on groundwater flow paths and travel times. The District has designated parts of western Alachua County and western Marion County as a Sensitive Karst Area Basin. A Sensitive Karst Area is a location in which the porous limestone of the Floridan aquifer occurs within 20 feet of the land surface, and in which there is 10 to 20 inches of annual recharge to the Floridan aquifer. The designation of an area as being within the Sensitive Karst Area Basin does not demonstrate that it does, or does not, have subsurface features that are karstic in nature, or that would provide a connection between the surficial aquifer and the Floridan aquifer. The western portion of the North Tract is within the Sensitive Karst Area Basin. The two intensive-use areas on the North Tract that have associated stormwater facilities -- the cattle unloading area and the processing facility -- are outside of the Sensitive Karst Area Basin. The evidence was persuasive that karst features are more prominent to the west of the North Tract. In order to evaluate the presence of karst features on the North Tract, Mr. Andreyev performed a “desktop-type evaluation,” with a minimal field survey. The desktop review included a review of aerial photographs and an investigation of available data, including the Florida Geological Survey database of sinkhole occurrence in the area. The aerial photographs showed circular depressions suggestive of karst activity west and southwest of the North Tract, but no such depressions on the North Tract. Soil borings taken on the North Tract indicated the presence of layers of clayey sand, clays, and silts at a depth of 70 to 80 feet. Well-drilling logs taken during the development of the wells used for an aquifer performance test on the North Tract showed the limestone of the Floridan aquifer starting at a depth below ground surface of 70 to 80 feet. Other boring data generated on the North Tract suggests that there is greater than 100 feet of clay and sandy clay overburden above the Floridan aquifer on and in the vicinity of the North Tract. Regardless of site-specific differences, the observed confining layer separating the surficial aquifer from the Floridan aquifer is substantial, and not indicative of a karst environment. Aquifer performance tests performed on the North Tract were consistent in showing that drawdown in the surficial aquifer from the tests was minimal to non-detectable, which is strong evidence of an intact and low-permeability confining layer. The presence of well-developed drainage features on the North Tract is further evidence of a unit of confinement that is restricting water from going deeper into the subsurface, and forcing it to runoff to low-lying surface water features. Petitioners’ witnesses did not perform any site- specific analysis of karst features on or around the Sleepy Creek property. Their understanding of the nature of the karst systems in the region was described as “hypothetical or [] conceptual.” Dr. Kincaid admitted that he knew of no conduits on or adjacent to the North Tract. As a result of the data collected from the North Tract, Mr. Hearn opined that the potential for karst features on the property that provide an opening to the upper Floridan aquifer “is extremely remote.” Mr. Hearn’s opinion is consistent with the preponderance of the evidence in this case, and is accepted. In the event a surface karst feature were to manifest itself, Sleepy Creek has proposed that the surface feature be filled and plugged to reestablish the integrity of the confining layer. More to the point, the development of a surficial karst feature in an area influenced by irrigation would be sufficient grounds for the SJRWMD to reevaluate and modify the CUP to account for any changed conditions affecting the assumptions and bases for issuance of the CUP. Silver Springs, the Silver River, and the Ocklawaha River The primary, almost exclusive concern of Petitioners was the effect of the modified CUP and the nutrients from the proposed cattle ranch on Silver Springs, the Silver River, and the Ocklawaha River. Silver Springs Silver Springs has long been a well-known attraction in Florida. It is located just to the east of Ocala, Florida. Many of the speakers at the public comment period of this proceeding spoke fondly of having frequented Silver Springs over the years, enjoying its crystal clear waters through famous glass-bottomed boats. For most of its recorded history, Silver Springs was the largest spring by volume in Florida. Beginning in the 1970s, it began to lose its advantage, and by the year 2000, Rainbow Springs, located in southwestern Marion County, surpassed Silver Springs as the state’s largest spring. Silver Springs exists at the top of the potentiometric surface of the Floridan aquifer. Being at the “top of the mountain,” when water levels in the Floridan aquifer decline, groundwater flow favors the lower elevation springs. Thus, surrounding springshed boundaries expand to take more water to maintain their baseflows, at the expense of the Silver Springs springshed, which contracts. Rainbow Springs shares an overlapping springshed with Silver Springs. The analogy used by Dr. Knight was of the aquifer as a bucket with holes at different levels, and with the Silver Springs “hole” near the top of the bucket. When the water level in the bucket is high, water will flow from the top hole. As the water level drops below that hole, it will preferentially flow from the lower holes. Rainbow Springs has a vent or outlet from the aquifer, that is 10 feet lower in elevation than that of Silver Springs. Coastal springs are lower still. Thus, as groundwater levels decline, the lower springs “pirate flow” from the upper springs. Since the first major studies of Silver Springs were conducted in the 1950s, the ecosystem of Silver Springs has undergone changes. The water clarity, though still high as compared to other springs, has been reduced by 10 to 15 percent. Since the 1950s, macrophytic plants, i.e., rooted plants with seeds and flowers, have declined in population, while epiphytic and benthic algae have increased. Those plants are sensitive to increases in nitrogen in the water. Thus, Dr. Knight’s opinion that increases in nitrogen emerging from Silver Springs, calculated to have risen from just over 0.4 mg/l in the 1950s, to 1.1 mg/l in 2004, and to up to 1.5 mg/l at present,1/ have caused the observed vegetative changes is accepted. Silver River Silver Springs forms the headwaters for the Silver River, a spring run 5 1/2 miles in length, at which point it becomes a primary input to the Ocklawaha River. Issues of water clarity and alteration of the vegetative regime that exist at Silver Springs are also evident in the Silver River. In addition, the reduction in flow allows for more tannic water to enter the river, further reducing clarity. Dr. Dunn recognized the vegetative changes in the river, and opined that the “hydraulic roughness” caused by the increase in vegetation is likely creating a spring pool backwater at Silver Springs, thereby suppressing some of the flow from the spring. The Silver River has been designated as an Outstanding Florida Water. There are currently no Minimum Flows and Levels established by the District for the Silver River. Ocklawaha River The Ocklawaha River originates near Leesburg, Florida, at the Harris Chain of Lakes, and runs northward past Silver Springs. The Silver River is a major contributor to the flow of the Ocklawaha River. Due to the contribution of the Silver River and other spring-fed tributaries, the Ocklawaha River can take on the appearance of a spring run during periods of low rainfall. Historically, the Ocklawaha River flowed unimpeded to its confluence with the St. Johns River in the vicinity of Palatka, Florida. In the 1960s, as part of the Cross-Florida Barge Canal project, the Rodman Dam was constructed across the Ocklawaha River north of the Sleepy Creek property, creating a large reservoir known as the Rodman Pool. Dr. Knight testified convincingly that the Rodman Dam and Pool have altered the Ocklawaha River ecosystem, precipitating a decline in migratory fish populations and an increase in filamentous algae. At the point at which the Ocklawaha River flows past the Sleepy Creek property, it retains its free-flowing characteristics. Mill Creek, which has its headwaters on the North Tract, is a tributary of the Ocklawaha River. The Ocklawaha River, from the Eureka Dam south, has been designated as an Outstanding Florida Water. However, the Ocklawaha River at the point at which Mill Creek or other potential surface water discharges from the Sleepy Creek property might enter the river are not included in the Outstanding Florida Water designation. There are currently no Minimum Flows and Levels established by the District for the Ocklawaha River. The Silver Springs Springshed A springshed is that area from which a spring draws water. Unlike a surface watershed boundary, which is fixed based on land features, contours, and elevations, a springshed boundary is flexible, and changes depending on a number of factors, including rainfall. As to Silver Springs, its springshed is largest during periods of more abundant rainfall when the aquifer is replenished, and smaller during drier periods when groundwater levels are down, and water moves preferentially to springs and discharge points that are lower in elevation. The evidence in this case was conflicting as to whether the North Tract is in or out of the Silver Springs springshed boundary. Dr. Kincaid indicated that under some of the springshed delineations, part of the North Tract was out of the springshed, but over the total period of record, it is within the springshed. Thus, it was Dr. Kincaid’s opinion that withdrawals anywhere within the region will preferentially impact Silver Springs, though he admitted that he did not have the ability to quantify his opinion. Dr. Knight testified that the North Tract is within the Silver Springs “maximum extent” springshed at least part of the time, if not all the time. He did not opine as to the period of time in which the Silver Springs springshed was at its maximum extent. Dr. Bottcher testified that the North Tract is not within the Silver Springs springshed because there is a piezometric rise between North Tract and Silver Springs. Thus, in his opinion, withdrawals at the North Tract would not be withdrawing water going to Silver Springs. Dr. Dunn agreed that the North Tract is on the groundwater divide for Silver Springs. In his view, the North Tract is sometimes in, and sometimes out of the springshed depending on the potentiometric surface. In his opinion, the greater probability is that the North Tract is more often outside of the Silver Springs springshed, with seasonal and year—to—year variation. Dr. Dunn’s opinion provides the most credible explanation of the extent to which the North Tract sits atop that portion of the lower Floridan aquifer that feeds to Silver Springs. Thus, it is found that the groundwater divide exists to the south of the North Tract for a majority of the time, and water entering the Floridan aquifer from the North Tract will, more often than not, flow away from Silver Springs. Silver Springs Flow Volume The Silver Springs daily water discharge has been monitored and recorded since 1932. Over the longest part of the period of record, up to the 1960s, flows at Silver Springs averaged about 800 cubic feet per second (cfs). Through 1989, there was a reasonable regression between rainfall and springflow, based on average rainfalls. The long-term average rainfall in Ocala was around 50 inches per year, and long-term springflow was about 800 cfs, with deviations from average generally consistent with one another. Between 1990 and 1999, the relationship between rainfall and springflow declined by about 80 cubic feet per second. Thus, with average rainfall of 50 inches per year, the average springflow was reduced to about 720 cfs. From 2000 to 2009, there was an additional decline, such that the total cumulative decline for the 20-year period through 2009 was 250 cfs. Dr. Dunn agreed with Dr. Knight that after 2000, there was an abrupt and persistent reduction in flow of about 165 cfs. However, Dr. Dunn did not believe the post-2000 flow reduction could be explained by rainfall directly, although average rainfall was less than normal. Likewise, groundwater withdrawals did not offer an adequate explanation. Dr. Dunn described a natural 30-year cycle of wetter and drier periods known as the Atlantic Multidecadal Oscillation (AMO) that has manifested itself over the area for the period of record. From the 1940s up through 1970, the area experienced an AMO wet cycle with generally higher than normal rainfall at the Ocala rain station. For the next 30-year period, from 1970 up to 2000, the Ocala area ranged from a little bit drier to some years in which it was very, very dry. Dr. Dunn attributed the 80 cfs decline in Silver Springs flow recorded in the 1990s to that lower rainfall cycle. After 2000, when the next AMO cycle would be expected to build up, as it did post—1940, it did not happen. Rather, there was a particularly dry period around 2000 that Dr. Dunn believes to have had a dramatic effect on the lack of recovery in the post-2000 flows in the Silver River. According to Mr. Jenkins, that period of deficient rainfall extended through 2010. Around the year 2001, the relationship between rainfall and flow changed such that for a given amount of rainfall, there was less flow in the Silver River, with flow dropping to as low as 535 cfs after 2001. It is that reduction in flow that Dr. Knight has attributed to groundwater withdrawals. It should be noted that the observed flow of Silver Springs that formed the 1995 baseline conditions for the North Central Florida groundwater model that will be discussed herein was approximately 706 cfs. At the time of the final hearing in August 2014, flow at Silver Springs was 675 cfs. The reason offered for the apparent partial recovery was higher levels of rainfall, though the issue was not explored in depth. For the ten-year period centered on the year 2000, local water use within Marion and Alachua County, closer to Silver Springs, changed little -- around one percent per year. From a regional perspective, groundwater use declined at about one percent per year for the period from 1990 to 2010. The figures prepared by Dr. Knight demonstrate that the Sleepy Creek project area is in an area that has a very low density of consumptive use permits as compared to areas adjacent to Silver Springs and more clearly in the Silver Springs springshed. In Dr. Dunn’s opinion, there were no significant changes in groundwater use either locally or regionally that would account for the flow reduction in Silver Springs from 1990 to 2010. In that regard, the environmental report prepared by Dr. Dunn and submitted with the CUP modification application estimated that groundwater withdrawals accounted for a reduction in flow at Silver Springs of approximately 20 cfs as measured against the period of record up to the year 2000, with most of that reduction attributable to population growth in Marion County. In the March 2014, environmental impacts report, Dr. Dunn described reductions in the stream flow of not only the Silver River, but of other tributaries of the lower Ocklawaha River, including the upper Ocklawaha River at Moss Bluff and Orange Creek. However, an evaluation of the Ocklawaha River water balance revealed there to be additional flow of approximately 50 cfs coming into the Ocklawaha River at other stations. Dr. Dunn suggested that changes to the vent characteristics of Silver Springs, and the backwater effects of increased vegetation in the Silver River, have resulted in a redistribution of pressure to other smaller springs that discharge to the Ocklawaha River, accounting for a portion of the diminished flow at Silver Springs. The Proposed Cattle Operation Virtually all beef cattle raised in Florida, upon reaching a weight of approximately 875 pounds, are shipped to Texas or Kansas to be fattened on grain to the final body weight of approximately 1,150 pounds, whereupon they are slaughtered and processed. The United States Department of Agriculture has a certification for grass—fed beef which requires that, after an animal is weaned, it can only be fed on green forage crops, including grasses, and on corn and grains that are cut green and before they set seed. The forage crops may be grazed or put into hay or silage and fed when grass and forage is dormant. The benefit of grass feeding is that a higher quality meat is produced, with a corresponding higher market value. Sleepy Creek plans to develop the property as a grass- fed beef production ranch, with pastures and related loading/unloading and slaughter/processing facilities where calves can be fattened on grass and green grain crops to a standard slaughter weight, and then slaughtered and processed locally. By so doing, Sleepy Creek expects to save the transportation and energy costs of shipping calves to the Midwest, and to generate jobs and revenues by employing local people to manage, finish, and process the cattle. As they currently exist, pastures proposed for irrigation have been cleared and seeded, and have “fairly good grass production.” The purpose of the irrigation is to enhance the production and quality of the grass in order to maintain the quality and reliability of feed necessary for the production of grass-fed beef. East Tract Cattle Operation The East Tract is 1,242 acres in size, substantially all of which was previously cleared, irrigated, and used for sod production. The proposed CUP permit authorizes the irrigation of 611 acres of pasture under six existing center pivots. The remaining 631 acres will be used as improved, but unirrigated, pasture. Under the proposed permit, a maximum of 1,207 cattle would be managed on the East Tract. Of that number, 707 cattle would be grazed on the irrigated paddocks, and 500 cattle would be grazed on the unirrigated improved pastures. If the decision is made to forego irrigation on the East Tract, with the water allocation being used on the North Tract or not at all, the number of cattle grazed on the six center pivot pastures would be decreased from 707 cattle to 484 cattle. The historic use of the East Tract as a sod farm resulted in high phosphorus levels in the soil from fertilization, which has made its way to Daisy Creek. Sleepy Creek has proposed a cattle density substantially below that allowed by application of the formulae in the Nutrient Management Plan in order to “mine” the phosphorus levels in the soil over time. North Tract Cattle Operation The larger North Tract includes most of the “new” ranch activities, having no previous irrigation, and having been put to primarily silvicultural use with limited pasture prior to its acquisition by Sleepy Creek. The ranch’s more intensive uses, i.e., the unloading corrals and the slaughter house, are located on the North Tract. The North Tract is 7,207 acres in size. Of that, 1,656 acres are proposed for irrigation by means of 15 center- pivot irrigation systems. In addition to the proposed irrigated pastures, the North Tract includes 2,382 acres of unirrigated improved pasture, of which approximately 10 percent is wooded. Under the proposed permit, a maximum of 6,371 cattle would be managed on the North Tract. Of that number, 3,497 cattle would be grazed on the irrigated paddocks (roughly 2.2 head of cattle per acre), and 2,374 cattle would graze on the improved pastures (up to 1.1 head of cattle per acre). The higher cattle density in the irrigated pastures can be maintained due to the higher quality grass produced as a result of irrigation. The remaining 500 cattle would be held temporarily in high-concentration corrals, either after offloading or while awaiting slaughter. On average, there will be fewer than 250 head of cattle staged in those high-concentration corrals at any one time. In the absence of irrigation, the improved pasture on the North Tract could sustain about 4,585 cattle. Nutrient Management Plan, Water Conservation Plan, and BMPs The CUP and ERP applications find much of their support in the implementation of the Nutrient Management Plan (NMP), the Water Conservation Plan, and Best Management Practices (BMPs). The NMP sets forth information designed to govern the day to day operations of the ranch. Those elements of the NMP that were the subject of substantive testimony and evidence at the hearing are discussed herein. Those elements not discussed herein are found to have been supported by Sleepy Creek’s prima facie case, without a preponderance of competent and substantial evidence to the contrary. The NMP includes a herd management plan, which describes rotational grazing and the movement of cattle from paddock to paddock, and establishes animal densities designed to maintain a balance of nutrients on the paddocks, and to prevent overgrazing. The NMP establishes fertilization practices, with the application of fertilizer based on crop tissue analysis to determine need and amount. Thus, the application of nitrogen- based fertilizer is restricted to that capable of ready uptake by the grasses and forage crops, limiting the amount of excess nitrogen that might run off of the pastures or infiltrate past the root zone. The NMP establishes operation and maintenance plans that incorporate maintenance and calibration of equipment, and management of high-use areas. The NMP requires that records be kept of, among other things, soil testing, nutrient application, herd rotation, application of irrigation water, and laboratory testing. The irrigation plan describes the manner and schedule for the application of water during each irrigation cycle. Irrigation schedules for grazed and cropped scenarios vary from pivot to pivot based primarily on soil type. The center pivots proposed for use employ high-efficiency drop irrigation heads, resulting in an 85 percent system efficiency factor, meaning that there is an expected evaporative loss of 15 percent of the water before it becomes available as water in the soil. That level of efficiency is greater than the system efficiency factor of 80 percent established in CUP A.H. section 12.5.2. Other features of the irrigation plan include the employment of an irrigation manager, installation of an on-site weather station, and cumulative tracking of rain and evapotranspiration with periodic verification of soil moisture conditions. The purpose of the water conservation practices is to avoid over application of water, limiting over-saturation and runoff from the irrigated pastures. Sleepy Creek has entered into a Notice of Intent to Implement Water Quality BMPs with the Florida Department of Agriculture and Consumer Services which is incorporated in the NMP and which requires the implementation of Best Management Practices.2/ Dr. Bottcher testified that implementation and compliance with the Water Quality Best Management Practices manual creates a presumption of compliance with water quality standards. His testimony in that regard is consistent with Department of Agriculture and Consumer Services rule 5M-11.003 (“implementation, in accordance with adopted rules, of BMPs that have been verified by the Florida Department of Environmental Protection as effective in reducing target pollutants provides a presumption of compliance with state water quality standards.”). Rotational Grazing Rotational grazing is a practice by which cattle are allowed to graze a pasture for a limited period of time, after which they are “rotated” to a different pasture. The 1,656 acres proposed for irrigation on the North Tract are to be divided into 15 center-pivot pastures. Each individual pasture will have 10 fenced paddocks. The 611 acres of irrigated pasture on the East Tract are divided into 6 center-pivot pastures. The outer fence for each irrigated pasture is to be a permanent “hard” fence. Separating the internal paddocks will be electric fences that can be lowered to allow cattle to move from paddock to paddock, and then raised after they have moved to the new paddock. The NMP for the North Tract provides that cattle are to be brought into individual irrigated pastures as a single herd of approximately 190 cattle and placed into one of the ten paddocks. They will be moved every one to three days to a new paddock, based upon growing conditions and the reduction in grass height resulting from grazing. In this way, the cattle are rotated within the irrigated pasture, with each paddock being used for one to three days, and then rested until each of the other paddocks have been used, whereupon it will again be used in the rotation. The East Tract NMP generally provides for rotation based on the height of the pasture grasses, but is designed to provide a uniform average of cattle per acre per year. Due to the desire to “mine” phosphorus deposited during the years of operation of the East Tract as a sod farm, the density of cattle on the irrigated East Tract pastures is about 30 percent less than that proposed for the North Tract. The East Tract NMP calls for a routine pasture rest period of 15 to 30 days. Unlike dairy farm pastures, where dairy cows traverse a fixed path to the milking barn several times a day, there will be minimal “travel lanes” within the pastures or between paddocks. There will be no travel lanes through wetlands. If nitrogen-based fertilizer is needed, based upon tissue analysis of the grass, fertilizer is proposed for application immediately after a paddock is vacated by the herd. By so doing, the grass within each paddock will have a sufficient period to grow and “flush up” without grazing or traffic, which results in a high—quality grass when the cattle come back around to feed. Sleepy Creek proposes that rotational grazing is to be practiced on improved pastures and irrigated pastures alike. The rotational practices on the improved East Tract and North Tract pastures are generally similar to those practiced on the irrigated pastures. The paddocks will have permanent watering troughs, with one trough serving two adjacent paddocks. The troughs will be raised to prevent “boggy areas” from forming around the trough. Since the area around the troughs will be of a higher use, Sleepy Creek proposes to periodically remove accumulated manure, and re-grade if necessary. Other cattle support items, including feed bunkers and shade structures are portable and can be moved as conditions demand. Forage Crop Production The primary forage crop on the irrigated pastures is to be Bermuda grass. Bermuda grass or other grass types tolerant of drier conditions will be used in unirrigated pastures. During the winter, when Bermuda grass stops growing, Sleepy Creek will overseed the North Tract pastures with ryegrass or other winter crops. Due to the limitation on irrigation water, the East Tract NMP calls for no over-seeding for production of winter crops. Crops do not grow uniformly during the course of a year. Rather, there are periods during which there are excess crops, and periods during which the crops are not growing enough to keep up with the needs of the cattle. During periods of excess, Sleepy Creek will cut those crops and store them as haylage to be fed to the cattle during lower growth periods. The North Tract management plan allows Sleepy Creek to dedicate one or more irrigated pastures for the exclusive production of haylage. If that option is used, cattle numbers will be reduced in proportion to the number of pastures dedicated to haylage production. As a result of the limit on irrigation, the East Tract NMP does not recommend growing supplemental feed on dedicated irrigation pivot pastures. Direct Wetland Impacts Approximately 100 acres proposed for irrigation are wetlands or wetland buffer. Those areas are predominantly isolated wetlands, though some have surface water connections to Mill Creek, a water of the state. Trees will be cut in the wetlands to allow the pivot to pass overhead. Tree cutting is an exempt agricultural activity that does not require a permit. There was no persuasive evidence that cutting trees will alter the fundamental benefit of the wetlands or damage water resources of the District. The wetlands and wetland buffer will be subject to the same watering and fertigation regimen as the irrigated pastures. The application of water to wetlands, done concurrently with the application of water to the pastures, will occur during periods in which the pasture soils are dry. The incidental application of water to the wetlands during dry periods will serve to maintain hydration of the wetlands, which is considered to be a benefit. Fertilizers will be applied through the irrigation arms, a process known as fertigation. Petitioners asserted that the application of fertilizer onto the wetlands beneath the pivot arms could result in some adverse effects to the wetlands. However, Petitioners did not quantify to what extent the wetlands might be affected, or otherwise describe the potential effects. Fertigation of the wetlands will promote the growth of wetland plants. Nitrogen applied through fertigation will be taken up by plants, or will be subject to denitrification -- a process discussed in greater detail herein -- in the anaerobic wetland soils. The preponderance of the evidence indicated that enhanced wetland plant growth would not rise to a level of concern. Since most of the affected wetlands are isolated wetlands, there is expected to be little or no discharge of nutrients from the wetlands. Even as to those wetlands that have a surface water connection, most, if not all of the additional nitrogen applied through fertigation will be accounted for by the combined effect of plant uptake and denitrification. Larger wetland areas within an irrigated pasture will be fenced at the buffer line to prevent cattle from entering. The NMP provided a blow-up of the proposed fencing related to a larger wetland on Pivot 8. Although other figures are not to the same scale, it appears that larger wetlands associated with Pivots 1, 2, 3, and 12 will be similarly fenced. Cattle would be allowed to go into the smaller, isolated wetlands. Cattle going into wetlands do not necessarily damage the wetlands. Any damage that may occur is a function of density, duration, and the number of cattle. The only direct evidence of potential damage to wetlands was the statement that “[i]f you have 6,371 [cattle] go into a wetland, there may be impacts.” The NMP provides that pasture use will be limited to herds of approximately 190 cattle, which will be rotated from paddock to paddock every two to three days, and which will allow for “rest” periods of approximately 20 days. There will be no travel lanes through any wetland. Thus, there is no evidence to support a finding that the cattle at the density, duration, and number proposed will cause direct adverse effects to wetlands on the property. High Concentration Areas Cattle brought to the facility are to be unloaded from trucks and temporarily corralled for inspection. For that period, the cattle will be tightly confined. Cattle that have reached their slaughter weight will be temporarily held in corrals associated with the processing plant. The stormwater retention ponds used to capture and store runoff from the offloading corral and the processing plant holding corral are part of a normal and customary agricultural activity, and are not part of the applications and approvals that are at issue in this proceeding. The retention ponds associated with the high-intensity areas do not require permits because they do not exceed one acre in size or impound more than 40 acre-feet of water. Nonetheless, issues related to the retention ponds were addressed by Petitioners and Sleepy Creek, and warrant discussion here. The retention ponds are designed to capture 100 percent of the runoff and entrained nutrients from the high concentration areas for a minimum of a 24—hour/25—year storm event. If rainfall occurs in excess of the designed storm, the design is such that upon reaching capacity, only new surface water coming to the retention pond will be discharged, and not that containing high concentrations of nutrients from the initial flush of stormwater runoff. Unlike the stormwater retention berms for the pastures, which are to be constructed from the first nine inches of permeable topsoil on the property, the corral retention ponds are to be excavated to a depth of six feet which, based on soil borings in the vicinity, will leave a minimum of two to four feet of clay beneath the retention ponds. In short, the excavation will penetrate into the clay layer underlying the pond sites, but will not penetrate through that layer. The excavated clay will be used to form the side slopes of the ponds, lining the permeable surficial layer and generally making the ponds impermeable. Organic materials entering the retention ponds will form an additional seal. An organic seal is important in areas in which retention ponds are constructed in sandy soil conditions. Organic sealing is less important in this case, where clay forms the barrier preventing nutrients from entering the surficial aquifer. Although the organic material is subject to periodic removal, the clay layer will remain to provide the impermeable barrier necessary to prevent leakage from the ponds. Dr. Bottcher testified that if, during excavation of the ponds, it was found that the remaining in-situ clay layer was too thin, Sleepy Creek would implement the standard practice of bringing additional clay to the site to ensure adequate thickness of the liner. Nutrient Balance The goal of the NMP is to create a balance of nutrients being applied to and taken up from the property. Nitrogen and phosphorus are the nutrients of primary concern, and are those for which specific management standards are proposed. Nutrient inputs to the NMP consist generally of deposition of cattle manure (which includes solid manure and urine), recycling of plant material and roots from the previous growing season, and application of supplemental fertilizer. Nutrient outputs to the NMP consist generally of volatization of ammonia to the atmosphere, uptake and utilization of the nutrients by the grass and crops, weight gain of the cattle, and absorption and denitrification of the nutrients in the soil. The NMP, and the various models discussed herein, average the grass and forage crop uptake and the manure deposition to match that of a 1,013 pound animal. That average weight takes into account the fact that cattle on the property will range from calf weight of approximately 850 pounds, to slaughter weight of 1150 pounds. Nutrients that are not accounted for in the balance, e.g., those that become entrained in stormwater or that pass through the plant root zone without being taken up, are subject to runoff to surface waters or discharge to groundwater. Generally, phosphorus not taken up by crops remains immobile in the soil. Unless there is a potential for runoff to surface waters, the nutrient balance is limited by the amount of nitrogen that can be taken up by the crops. Due to the composition of the soils on the property, the high water table, and the relatively shallow confining layer, there is a potential for surface runoff. Thus, the NMP was developed using phosphorus as the limiting nutrient, which results in nutrient application being limited by the “P-index.” A total of 108 pounds of phosphorus per acre/per year can be taken up and used by the irrigated pasture grasses and forage crops. Therefore, the total number of cattle that can be supported on the irrigated pastures is that which, as a herd, will deposit an average of 108 pounds of phosphorus per year over the irrigated acreage. Therefore, Sleepy Creek has proposed a herd size and density based on calculations demonstrating that the total phosphorus contained in the waste excreted by the cattle equals the amount taken up by the crops. A herd producing 108 pounds per acre per year of phosphorus is calculated to produce 147 pounds of nitrogen per acre per year. The Bermuda grass and forage crops proposed for the irrigated fields require 420 pounds of nitrogen per acre per year. As a result of the nitrogen deficiency, additional nitrogen-based fertilizer to make up the shortfall is required to maintain the crops. Since phosphorus needs are accounted for by animal deposition, the fertilizer will have no phosphorus. The NMP requires routine soil and plant tissue tests to determine the amount of nitrogen fertilizer needed. By basing the application of nitrogen on measured rather than calculated needs, variations in inputs, including plant decomposition and atmospheric deposition, and outputs, including those affected by weather, can be accounted for, bringing the full nutrient balance into consideration. The numeric values for crop uptakes, manure deposition, and other estimates upon which the NMP was developed were based upon literature, values, and research performed and published by the University of Florida and the Natural Resource Conservation Service. Dr. Bottcher testified convincingly that the use of such values is a proven and reliable method of developing a balance for the operation of similar agricultural operations. A primary criticism of the NMP was its expressed intent to “reduce” or “minimize” the transport of nutrients to surface waters and groundwater, rather than to “negate” or “prevent” such transport. Petitioners argue that complete prevention of the transport of nutrients from the property is necessary to meet the standards necessary for issuance of the CUP and ERP. Mr. Drummond went into some detail regarding the total mass of nutrients expected to be deposited onto the ground from the cattle, exclusive of fertilizer application. In the course of his testimony, he suggested that the majority of the nutrients deposited on the land surface “are going to make it to the surficial aquifer and then be carried either to the Floridan or laterally with the groundwater flow.” However, Mr. Drummond performed no analysis on the fate of nitrogen through uptake by crops, volatization, or soil treatment, and did not quantify the infiltration of nitrogen to groundwater. Furthermore, he was not able to provide any quantifiable estimate on any effect of nutrients on Mill Creek, the Ocklawaha River, or Silver Springs. In light of the effectiveness of the nutrient balance and other elements of the NMP, along with the retention berm system that will be discussed herein, Mr. Drummond’s assessment of the nutrients that might be expected to impact water resources of the District is contrary to the greater weight of the evidence. Mr. Drummond’s testimony also runs counter to that of Dr. Kincaid, who performed a particle track analysis of the fate of water recharge from the North Tract. In short, Dr. Kincaid calculated that of the water that makes it as recharge from the North Tract to the surficial aquifer, less than one percent is expected to make its way to the upper Floridan aquifer, with that portion originating from the vicinity of Pivot 6. Recharge from the other 14 irrigated pastures was ultimately accounted for by evapotranspiration or emerged at the surface and found its way to Mill Creek. The preponderance of the competent, substantial evidence adduced at the final hearing supports the effectiveness of the NMPs for the North Tract and East Tract at managing the application and use of nutrients on the property, and minimizing the transport of nutrients to surface water and groundwater resources of the District. North Central Florida Model All of the experts involved in this proceeding agreed that the use of groundwater models is necessary to simulate what might occur below the surface of the ground. Models represent complex systems by applying data from known conditions and impacts measured over a period of years to simulate the effects of new conditions. Models are imperfect, but are the best means of predicting the effects of stresses on complex and unseen subsurface systems. The North Central Florida (NCF) model is used to simulate impacts of water withdrawals on local and regional groundwater levels and flows. The NCF model simulates the surficial aquifer, the upper Floridan aquifer, and the lower Floridan aquifer. Those aquifers are separated from one another by relatively impervious confining units. The intermediate confining unit separates the surficial aquifer from the upper Floridan aquifer. The intermediate confining unit is not present in all locations simulated by the NCF model. However, the evidence is persuasive that the intermediate confining unit is continuous at the North Tract, and serves to effectively isolate the surficial aquifer from the upper Floridan aquifer. The NCF model is not a perfect depiction of what exists under the land surface of the North Tract or elsewhere. It was, however, acknowledged by the testifying experts in this case, despite disagreements as to the extent of error inherent in the model, to be the best available tool for calculating the effects of withdrawals of water within the boundary of the model. The NCF model was developed and calibrated over a period of years, is updated routinely as data becomes available, and has undergone peer review. Aquifer Performance Tests In order to gather site-specific data regarding the characteristics of the aquifer beneath the Sleepy Creek property, a series of three aquifer performance tests (APTs) was conducted on the North Tract. The first two tests were performed by Sleepy Creek, and the third by the District. An APT serves to induce stress on the aquifer by pumping from a well at a high rate. By observing changes in groundwater levels in observation wells, which can be at varying distances from the extraction well, one can extrapolate the nature of the subsurface. In addition, well-completion reports for the various withdrawal and observation wells provide actual data regarding the composition of subsurface soils, clays, and features of the property. The APT is particularly useful in evaluating the ability of the aquifer to produce water, and in calculating the transmissivity of the aquifer. Transmissivity is a measure of the rate at which a substance passes through a medium and, as relevant to this case, measures how groundwater flows through an aquifer. The APTs demonstrated that the Floridan aquifer is capable of producing water at the rate requested. The APT drawdown contour measured in the upper Floridan aquifer was greater than that predicted from a simple run of the NCF model, but the lateral extent of the drawdown was less than predicted. The most reasonable conclusion to be drawn from the combination of greater than expected drawdown in the upper Floridan aquifer with less than expected extent is that the transmissivity of the aquifer beneath the North Tract is lower than the NCF model assumptions. The conclusion that the transmissivity of the aquifer at the North Tract is lower than previously estimated means that impacts from groundwater extraction would tend to be more vertical than horizontal, i.e., the drawdown would be greater, but would be more localized. As such, for areas of lower than estimated transmissivity, modeling would over-estimate off-site impacts from the extraction. NCF Modeling Scenarios The initial NCF modeling runs were based on an assumed withdrawal of 2.39 mgd, an earlier -- though withdrawn - - proposal. The evidence suggests that the simulated well placement for the 2.39 mgd model run was entirely on the North Tract. Thus, the results of the model based on that withdrawal have some limited relevance, especially given that the proposed CUP allows for all of the requested 1.46 mgd of water to be withdrawn from North Tract wells at the option of Sleepy Creek, but will over-predict impacts from the permitted rate of withdrawal. A factor that was suggested as causing a further over-prediction of drawdown in the 2.39 mgd model run was the decision, made at the request of the District, to exclude the input of data of additional recharge to the surficial aquifer, wetlands and surface waters from the irrigation, and the resulting diminution in soil storage capacity. Although there is some merit to the suggestion that omitting recharge made the model results “excessively conservative,” the addition of recharge to the model would not substantially alter the predicted impacts. A model run was subsequently performed based on a presumed withdrawal of 1.54 mgd, a rate that remains slightly more than, but still representative of, the requested amount of 1.46 mgd. The 1.54 mgd model run included an input for irrigation recharge. The simulated extraction points were placed on the East Tract and North Tract in the general configuration as requested in the CUP application. The NCF is designed to model the impacts of a withdrawal based upon various scenarios, identified at the hearing as Scenarios A, B, C, and D. Scenario A is the baseline condition for the NCF model, and represents the impacts of all legal users of water at their estimated actual flow rates as they existed in 1995. Scenario B is all existing users, not including the applicant, at end-of-permit allocations. Scenario C is all existing users, including the applicant, at current end-of-permit allocations. Scenario D is all permittees at full allocation, except the applicant which is modeled at the requested (i.e., new or modified) end-of-permit allocation. To simulate the effects of the CUP modification, simulations were performed on scenarios A, C, and D. In order to measure the specific impact of the modification of the CUP, the Scenario C impacts to the surficial, upper Floridan, and lower Floridan aquifers were compared with the Scenario D impacts to those aquifers. In order to measure the cumulative impact of the CUP, the Scenario A actual-use baseline condition was compared to the Scenario D condition which predicts the impacts of all permitted users, including the applicant, pumping at full end-of-permit allocations. The results of the NCF modeling indicate the following: 2.39 mgd - Specific Impact The surficial aquifer drawdown from the simulated 2.39 mgd withdrawal was less than 0.05 feet on-site and off- site, except to the west of the North Tract, at which a drawdown of 0.07 feet was predicted. The upper Floridan aquifer drawdown from the 2.39 mgd withdrawal was predicted at between 0.30 and 0.12 feet on-site, and between 0.30 and 0.01 feet off-site. The higher off-site figures are immediately proximate to the property. The lower Floridan aquifer drawdown from the 2.39 mgd withdrawal was predicted at less than 0.05 feet at all locations, and at or less than 0.02 feet within six miles of the North Tract. 2.39 mgd - Cumulative Impact The cumulative impact to the surficial aquifer from all permitted users, including a 2.39 mgd Sleepy Creek withdrawal, was less than 0.05 feet on-site, and off-site to the north and east, except to the west of the North Tract, at which a drawdown of 0.07 feet was predicted. The cumulative impact to the upper Floridan aquifer from all permitted users, including a 2.39 mgd Sleepy Creek withdrawal, ranged from 0.4 feet to 0.8 feet over all pertinent locations. The cumulative impact to the lower Floridan aquifer from all permitted users, including a 2.39 mgd Sleepy Creek withdrawal, ranged from 1.0 to 1.9 feet over all pertinent locations. The conclusion drawn by Mr. Andreyev that the predicted impacts to the lower Floridan are almost entirely from other end-of-permit user withdrawals is supported by the evidence and accepted. 1.54 mgd - Specific Impact The NCF model runs based on the more representative 1.54 mgd withdrawal predicted a surficial aquifer drawdown of less than 0.01 feet (i.e., no drawdown contour shown) on the North Tract, and a 0.01 to 0.02 foot drawdown at the location of the East Tract. The drawdown of the upper Floridan aquifer from the CUP modification was predicted at up to 0.07 feet on the property, and generally less than 0.05 feet off-site. There were no drawdown contours at the minimum 0.01 foot level that came within 9 miles of Silver Springs. The lower Floridan aquifer drawdown from the CUP modification was predicted at less than 0.01 feet (i.e., no drawdown contour shown) at all locations. 1.54 mgd - Cumulative Impact A comparison of the cumulative drawdown contours for the 2.36 mgd model and 1.54 mgd model show there to be a significant decrease in predicted drawdowns to the surficial and upper Floridan aquifers, with the decrease in the upper Floridan aquifer drawdown being relatively substantial, i.e., from 0.5 to 0.8 feet on-site predicted for the 2.36 mgd withdrawal, to 0.4 to 0.5 feet on-site for the 1.54 mgd model. Given the small predicted individual impact of the CUP on the upper Floridan aquifer, the evidence is persuasive that the cumulative impacts are the result of other end-of-permit user withdrawals. The drawdown contour for the lower Floridan aquifer predicted by the 1.54 mgd model is almost identical to that of the 2.36 mgd model, thus supporting the conclusion that predicted impacts to the lower Floridan are almost entirely from other end-of-permit user withdrawals. Modeled Effect on Silver Springs As a result of the relocation of the extraction wells from the East Tract to the North Tract, the NCF model run at the 1.54 mgd withdrawal rate predicted springflow at Silver Springs to increase by 0.15 cfs. The net cumulative impact in spring flow as measured from 1995 conditions to the scenario in which all legal users, including Sleepy Creek, are pumping at full capacity at their end-of-permit rates for one year3/ is roughly 35.4 cfs, which is approximately 5 percent of Silver Springs’ current flow. However, as a result of the redistribution of the Sleepy Creek withdrawal, which is, in its current iteration, a legal and permitted use, the cumulative effect of the CUP modification at issue is an increase in flow of 0.l5 cfs. Dr. Kincaid agreed that there is more of an impact to Silver Springs when the pumping allowed by the CUP is located on the East Tract than there is on the North Tract, but that the degree of difference is very small. Dr. Knight testified that effect on the flow of Silver Springs from relocating the 1.46 mgd withdrawal from the East Tract to the North Tract would be “zero.” The predicted increase of 0.15 cfs is admittedly miniscule when compared to the current Silver Springs springflow of approximately 675 cfs. However, as small as the modeled increase may be -- perhaps smaller than its “level of certainty” -- it remains the best evidence that the impact of the CUP modification to the flow of Silver Springs will be insignificant at worst, and beneficial at best. Opposition to the NCF Model Petitioners submitted considerable evidence designed to call the results generated by the District’s and Sleepy Creek’s NCF modeling into question. Karst Features A primary criticism of the validity of the NCF model was its purported inability to account for the presence of karst features, including conduits, and their effect on the results. It was Dr. Kincaid’s opinion that the NCF model assigned transmissivity values that were too high, which he attributed to the presence of karst features that are collecting flow and delivering it to springs. He asserted that, instead of assuming the presence of karst features, the model was adjusted to raise the overall capacity of the porous medium to transmit water, and thereby match the observed flows. In his opinion, the transmissivity values of the equivalent porous media were raised so much that the model can no longer be used to predict drawdowns. That alleged deficiency in the model is insufficient for two reasons. First, as previously discussed in greater detail, the preponderance of the evidence in this case supports a finding that there are no karst features in the vicinity of the North Tract that would provide preferential pathways for water flow so as to skew the results of the NCF model. Second, Dr. Kincaid, while acknowledging that the NCF model is the best available tool for predicting impacts from groundwater extraction on the aquifer, suggested that a hybrid porous media and conduit model would be a better means of predicting impacts, the development of which would take two years or more. There is no basis for the establishment of a de facto moratorium on CUP permitting while waiting for the development of a different and, in this case, unnecessary model. For the reasons set forth herein, it is found that the NCF model is sufficient to accurately and adequately predict the effects of the Sleepy Creek groundwater withdrawals on the aquifers underlying the property, and to provide reasonable assurance that the standards for such withdrawals have been met. Recharge to the Aquifer Petitioners argued that the modeling results showing little significant drawdown were dependent on the application of unrealistic values for recharge or return flow from irrigation. In a groundwater model, as in the physical world, some portion of the water extracted from the aquifer is predicted to be returned to the aquifer as recharge. If more water is applied to the land surface than is being accounted for by evaporation, plant uptake and evapotranspiration, surface runoff, and other processes, that excess water may seep down into the aquifer as recharge. Recharge serves to replenish the aquifer and offset the effects of the groundwater withdrawal. Dr. Kincaid opined that the NCF modeling performed for the CUP application assigned too much water from recharge, offsetting the model's prediction of impacts to other features. It is reasonable to assume that there is some recharge associated with both agricultural and public supply uses. However, the evidence suggests that the impact of recharge on the overall NCF model results is insignificant on the predicted impacts to Silver Springs, the issue of primary concern. Mr. Hearn ran a simulation using the NCF model in which all variables were held constant, except for recharge. The difference between the “with recharge” and “without recharge" simulations at Silver Springs was 0.002 cfs. That difference is not significant, and is not suggestive of adverse impacts on Silver Springs from the CUP modification. Dr. Kincaid testified that “the recharge offset on the property is mostly impacting the surficial aquifer,” and that “the addition of recharge in this case didn't have much of an impact on the upper Floridan aquifer system.” As such, the effect of adding recharge to the model would be as to the effect of groundwater withdrawal on wetlands or surface water bodies, and not on springs. As previously detailed, the drawdown of the surficial aquifer simulated for the 2.39 mgd “no recharge” scenario were less than 0.05 feet on-site and off-site, except for a predicted 0.07 foot drawdown to the west of the North Tract. The predicted drawdown of the surficial aquifer for the 1.54 mgd “with recharge” scenario was 0.02 feet or less. The preponderance of the evidence supports a finding that drawdowns of either degree are less than that at which adverse impacts to wetlands or surface waters would occur. Thus, issues related to the recharge or return flows from irrigation are insufficient to support a finding or conclusion that the NCF model failed to provide reasonable assurance that the standards for issuance of the CUP modification were met. External Boundaries The boundaries of the NCF model are not isolated from the rest of the physical world. Rather, groundwater flows into the modeled area from multiple directions, and out of the modeled area in multiple directions. Inflows to the model area are comprised of recharge, which is an assigned value, and includes water infiltrating and recharging the aquifer from surface waters; injection wells; upward and downward leakage from lower aquifers; and flow across the external horizontal boundaries. Outflows from the model area include evapotranspiration; discharge to surface waters, including springs and rivers; extraction from wells; upward and downward leakage from lower aquifers; and flow against the external model boundaries. Dr. Kincaid testified that flow across the external model boundary is an unknown and unverifiable quantity which increases the uncertainty in the model. He asserted that in the calibrated version of the model, there is no way to check those flows against data. His conclusion was that the inability of the NCF model to accurately account for external boundary flow made the margin of error so great as to make the model an unreliable tool with which to assess whether the withdrawal approved by the proposed CUP modification will increase or decrease drawdown at Silver Springs. The District correlates the NCF model boundaries with a much larger model developed by the United States Geological Survey, the Peninsula of Florida Model, more commonly referred to as the Mega Model, which encompasses most of the State of Florida and part of Southeast Georgia. The Mega Model provides a means to acknowledge that there are stresses outside the NCF model, and to adjust boundary conditions to account for those stresses. The NCF is one of several models that are subsets of the Mega Model, with the grids of the two models being “nested” together. The 1995 base year of the NCF model is sufficiently similar to the 1993-1994 base year of the Mega Model as to allow for a comparison of simulated drawdowns calculated by each of the models. By running a Mega Model simulation of future water use, and applying the change in that use from 1993 base year conditions, the District was able to come to a representative prediction of specific boundary conditions for the 1995 NCF base year, which were then used as the baseline for simulations of subsequent conditions. In its review of the CUP modification, the District conducted a model validation simulation to measure the accuracy of the NCF model against observed conditions, with the conditions of interest being the water flow at Silver Springs. The District ran a simulation using the best information available as to water use in the year 2010, the calculated boundary conditions, irrigation, pumping, recharge, climatic conditions, and generally “everything that we think constitutes that year.” The discharge of water at Silver Springs in 2010 was measured at 580 cfs. The discharge simulated by the NCF model was 545 cfs. Thus, the discharge predicted by the NCF model simulation was within six percent of the observed discharge. Such a result is generally considered in the modeling community to be “a home run.” Petitioners’ objections to the calculation of boundary conditions for the NCF model are insufficient to support a finding that the NCF model is not an appropriate and accurate tool for determining that reasonable assurance has been provided that the standards for issuance of the CUP modification were met. Cumulative Impact Error As part of the District’s efforts to continually refine the NCF, and in conjunction with a draft minimum flows and levels report for Silver Springs and the Silver River, the cumulative NCF model results for the period of baseline to 2010 were compared with the simulated results from the Northern District Model (NDF), a larger model that overlapped the NCF. As a result of the comparison, which yielded different results, it was discovered that the modeler had “turned off” not only the withdrawal pumps, but inputs to the aquifer from drainage wells and sinkholes as well. When those inputs were put back into the model run, and effects calculated only from withdrawals between the “pumps-off” condition and 2010 pumping conditions, the cumulative effect of the withdrawals was adjusted from a reduction in the flow at Silver Springs of 29 cfs to a reduction of between 45 and 50 cfs, an effect described as “counterintuitive.” Although that result has not undergone peer review, and remains subject to further review and comparison with the Mega Model, it was accepted by the District representative, Mr. Bartol. Petitioners seized upon the results of the comparison model run as evidence of the inaccuracy and unreliability of the NCF model. However, the error in the NCF model run was not the result of deficiencies in the model, but was a data input error. Despite the error in the estimate of the cumulative effect of all users at 2010 levels, the evidence in this case does not support a finding that the more recent estimates of specific impact from the CUP at issue were in error. NCF Model Conclusion As has been discussed herein, a model is generally the best means by which to calculate conditions and effects that cannot be directly observed. The NCF model is recognized as being the best tool available for determining the subsurface conditions of the model domain, having been calibrated over a period of years and subject to peer review. It should be recognized that the simulations run using the NCF model represent the worst—case scenario, with all permittees simultaneously drawing at their full end-of-permit allocations. There is merit to the description of that occurrence as being “very remote.” Thus, the results of the modeling represent a conservative estimate of potential drawdown and impacts. While the NCF model is subject to uncertainty, as is any method of predicting the effects of conditions that cannot be seen, the model provides reasonable assurance that the conditions simulated are representative of the conditions that will occur as a result of the withdrawals authorized by the CUP modification. Environmental Resource Permit The irrigation proposed by the CUP will result in runoff from the North Tract irrigated pastures in excess of that expected from the improved pastures, due in large measure to the diminished storage capacity of the soil. Irrigation water will be applied when the soils are dry, and capable of absorbing water not subject to evaporation or plant uptake. The irrigation water will fill the storage space that would exist without irrigation. With irrigation water taking up the capacity of the soil to hold water, soils beneath the irrigation pivots will be less capable of retaining additional moisture during storm events. Thus, there is an increased likelihood of runoff from the irrigated pastures over that expected with dry soils. The increase in runoff is expected to be relatively small, since there should be little or no irrigation needed during the normal summer wet season. The additional runoff may have increased nutrient levels due to the increased cattle density made possible by the irrigation of the pastures. The CUP has a no—impact requirement for water quality resulting from the irrigation of the improved pasture. Thus, nutrients leaving the irrigated pastures may not exceed those calculated to be leaving the existing pre-development use as improved pastures. Retention Berms The additional runoff and nutrient load is proposed to be addressed by constructing a system of retention berms, approximately 50,0004/ feet in length, which is intended to intercept, retain, and provide treatment for runoff from the irrigated pasture. The goal of the system is to ensure that post—development nutrient loading from the proposed irrigated pastures will not exceed the pre—development nutrient loading from the existing improved pastures. An ERP permit is required for the construction of the berm system, since the area needed for the construction of the berms is greater than the one acre in size, and since the berms have the capability of impounding more than 40 acre-feet of water. The berms are to be constructed by excavating the top nine inches of sandy, permeable topsoil and using that permeable soil to create the berms, which will be 1 to 2 feet in height. The water storage areas created by the excavation will have flat or horizontal bottoms, and will be very shallow with the capacity to retain approximately a foot of water. The berms will be planted with pasture grasses after construction to provide vegetative cover. The retention berm system is proposed to be built in segments, with the segment designed to capture runoff from a particular center pivot pasture to be constructed prior to the commencement of irrigation from that center pivot. A continuous clay layer underlies the areas in which the berms are to be constructed. The clay layer varies from 18 to 36 inches below the ground surface, with at least one location being as much as five feet below the ground surface. As such, after nine inches of soil is scraped away to create the water retention area and construct the berm, there will remain a layer of permeable sandy material above the clay. The berms are to be constructed at least 25 feet landward of any jurisdictional wetland, creating a “safe upland line.” Thus, the construction, operation, and maintenance of the retention berms and redistribution swales will result in no direct impacts to jurisdictional wetlands or other surface waters. There will be no agricultural activities, e.g., tilling, planting, or mowing, within the 25-foot buffers, and the buffers will be allowed to establish with native vegetation to provide additional protection for downgradient wetlands. As stormwater runoff flows from the irrigated pastures, it may, in places, create concentrated flow ways. Redistribution swales will be built in those areas to spread any remaining overland flow of water and reestablish sheet flow to the retention berm system. At any point at which water may overtop a berm, the berm will be hardened with rip—rap to insure its integrity. The berms are designed to intercept and collect overland flow from the pastures and temporarily store it behind the berms, regaining the soil storage volume lost through irrigation. A portion of the runoff intercepted by the berm system will evaporate. The majority will infiltrate either through the berm, or vertically into the subsurface soils beneath it. When the surficial soils become saturated, further vertical movement will be stopped by the impermeable clay layer underlying the site. The runoff water will then move horizontally until it reemerges into downstream wetland systems. Thus, the berm system is not expected to have a measurable impact on the hydroperiod of the wetlands on the North Tract. Phosphorus Removal Phosphorus tends to get “tied up” in soil as it moves through it. Phosphorus reduction occurs easily in permeable soil systems because it is removed from the water through a chemical absorption process that is not dependent on the environment of the soil. As the soils in the retention areas and berms go through drying cycles, the absorption capacity is regenerated. Thus, the retention system will effectively account for any increase in phosphorus resulting from the increased cattle density allowed by the irrigation such that there is expected to be no increase in phosphorus levels beyond the berm. Nitrogen Removal When manure is deposited on the ground, primarily as high pH urine, the urea is quickly converted to ammonia, which experiences a loss of 40 to 50 percent of the nitrogen to volatization. Soil conditions during dry weather conditions are generally aerobic. Remaining ammonia in the manure is converted by aerobic bacteria in the soil to nitrates and nitrites. Converted nitrates and nitrites from manure, along with nitrogen from fertilizer, is readily available for uptake as food by plants, including grasses and forage crops. Nitrates and nitrites are mobile in water. Therefore, during rain events of sufficient intensity to create runoff, the nitrogen can be transported downstream towards wetlands and other receiving waters, or percolate downward through the soil until blocked by an impervious barrier. During storm events, the soils above the clay confining layer and the lower parts of the pervious berms become saturated. Those saturated soils are drained of oxygen and become anaerobic. When nitrates and nitrites encounter saturated conditions, they provide food for anaerobic bacteria that exist in those conditions. The bacteria convert nitrates and nitrites to elemental nitrogen, which has no adverse impact on surface waters or groundwater. That process, known as denitrification, is enhanced in the presence of organic material. The soils from which the berms are constructed have a considerable organic component. In addition to the denitrification that occurs in the saturated conditions in and underlying the berms, remaining nitrogen compounds that reemerge into the downstream wetlands are likely to encounter organic wetland-type soil conditions. Organic wetland soils are anaerobic in nature, and will result in further, almost immediate denitrification of the nitrates and nitrites in the emerging water. Calculation of Volume - BMPTRAINS Model The calculation of the volume necessary to capture and store excess runoff from the irrigated pastures was performed by Dr. Wanielista using the BMPTRAINS model. BMPTRAINS is a simple, easy to use spreadsheet model. Its ease of use does not suggest that it is less than reliable. The model has been used as a method of calculating storage volumes in many conditions over a period of more than 40 years. The model was used to calculate the storage volumes necessary to provide storage and treatment of runoff from fifteen “basins” that had a control or a Best Management Practice associated with them. All of the basins were calculated as being underlain by soils in poorly-drained hydrologic soil Group D, except for the basin in the vicinity of Pivot 6, which is underlain by the more well-drained soil Group A. The model assumed about percent of the property to have soil Group A soils, an assumption that is supported by the evidence. Soil moisture conditions on the property were calculated by application of data regarding rainfall events and times, the irrigation schedule, and the amount of irrigation water projected for use over a year. The soil moisture condition was used to determine the amount of water that could be stored in the on-site soils, known as the storage coefficient. Once the storage coefficient was determined, that data was used to calculate the amount of water that would be expected to run off of the North Tract, known as the curve number. The curve number is adjusted by the extent to which the storage within a soil column is filled by the application of irrigation water, making it unable to store additional rainfall. As soil storage goes down, the curve number goes up. Thus, a curve number that approaches 100 means that more water is predicted to run off. Conversely, a lower curve number means that less water is predicted to run off. The pre-development curve number for the North Tract was based on the property being an unirrigated, poor grass area. A post-development curve number was assigned to the property that reflected a wet condition representative of the irrigated soils beneath the pivots. In calculating the storage volume necessary to handle runoff from the basins, the wet condition curve number was adjusted based on the fact that there is a mixture of irrigated and unirrigated general pasture within each basin to be served by a segment of the retention berm system, and by the estimated 15 percent of the time that the irrigation areas would be in a drier condition. In addition, the number was adjusted to reflect the 8 to 10 inches of additional evapotranspiration that occurs as a result of irrigation. The BMPTRAINS model was based on average annual nutrient-loading conditions, with water quality data collected at a suitable point within Reach 22, the receiving waterbody. The effects of nutrients from the irrigated pastures on receiving waterbodies is, in terms of the model, best represented by average annual conditions, rather than a single highest-observed nutrient value. Pre-development loading figures were based on the existing use of the property as unirrigated general pasture. The pre-development phosphorus loading figure was calculated at an average event mean concentration (EMC) of 0.421 milligrams per liter (mg/l). The post—condition phosphorus loading figure was calculated at an EMC of 0.621 mg/l. Therefore, in order to achieve pre-development levels of phosphorus, treatment to achieve a reduction in phosphorus of approximately 36 percent was determined to be necessary. The pre-development nitrogen loading figure was calculated at an EMC of 2.6 mg/l. The post—condition nitrogen loading figure was calculated at an EMC of 3.3 mg/l. Therefore, in order to achieve pre-development levels of nitrogen, treatment to achieve a reduction in nitrogen of approximately 25 percent was determined to be necessary. The limiting value for the design of the retention berms is phosphorus. To achieve post-development concentrations that are equal to or less than pre-development concentrations, the treatment volume of the berm system must be sufficient to allow for the removal of 36 percent of the nutrients in water being retained and treated behind the berms, which represents the necessary percentage of phosphorus. In order to achieve the 36 percent reduction required for phosphorus, the retention berm system must be capable of retaining approximately 38 acre—feet of water from the 15 basins. In order to achieve that retention volume, a berm length of approximately 50,000 linear feet was determined to be necessary, with an average depth of retention behind the berms of one foot. The proposed length of the berms is sufficient to retain the requisite volume of water to achieve a reduction in phosphorus of 36 percent. Thus, the post-development/irrigation levels of phosphorus from runoff are expected to be no greater than pre-development/general pasture levels of phosphorus from runoff. By basing the berm length and volume on that necessary for the treatment of phosphorus, there will be storage volume that is greater than required for a 25 percent reduction in nitrogen. Thus, the post-development/irrigation levels of nitrogen from runoff are expected to be less than pre- development/general pasture levels of nitrogen from runoff. Mr. Drummond admitted that the design of the retention berms “shows there is some reduction, potentially, but it's not going to totally clean up the nutrients.” Such a total clean-up is not required. Rather, it is sufficient that there is nutrient removal to pre-development levels, so that there is no additional pollutant loading from the permitted activities. Reasonable assurance that such additional loading is not expected to occur was provided. Despite Mr. Drummond’s criticism of the BMPTRAINS model, he did not quantify nutrient loading on the North Tract, and was unable to determine whether post-development concentrations of nutrients would increase over pre-development levels. As such, there was insufficient evidence to counter the results of the BMPTRAINS modeling. Watershed Assessment Model In order to further assess potential water quantity and water quality impacts to surface water bodies, and to confirm stormwater retention area and volume necessary to meet pre-development conditions, Sleepy Creek utilized the Watershed Assessment Model (WAM). The WAM is a peer-reviewed model that is widely accepted by national, state, and local regulatory entities. The WAM was designed to simulate water balance and nutrient impacts of varying land uses. It was used in this case to simulate and provide a quantitative measure of the anticipated impacts of irrigation on receiving water bodies, including Mill Creek, Daisy Creek, the Ocklawaha River, and Silver Springs. Inputs to the model include land conditions, soil conditions, rain and climate conditions, and water conveyance systems found on the property. In order to calculate the extent to which nutrients applied to the land surface might affect receiving waters, a time series of surface water and groundwater flow is “routed” through the modeled watershed and to the various outlets from the system, all of which have assimilation algorithms that represent the types of nutrient uptakes expected to occur as water goes through the system. Simulations were performed on the North Tract in its condition prior to acquisition by Sleepy Creek, in its current “exempted improved pasture condition,” and in its proposed “post—development” pivot-irrigation condition. The simulations assessed impacts of the site conditions on surface waters at the point at which they leave the property and discharge to Mill Creek, and at the point where Mill Creek merges into the Ocklawaha River. The baseline condition for measuring changes in nutrient concentrations was determined to be that lawfully existing at the time the application was made. Had there been any suggestion of illegality or impropriety in Sleepy Creek’s actions in clearing the timber and creating improved pasture, a different baseline might be warranted. However, no such illegality or impropriety was shown, and the SJRWMD rules create no procedure for “looking back” to previous land uses and conditions that were legally changed. Thus, the “exempted improved pasture condition” nutrient levels are appropriate for comparison with irrigated pasture nutrient levels. The WAM simulations indicated that nitrogen resulting from the irrigation of the North Tract pastures would be reduced at the outflow to Mill Creek at the Reach 22 stream segment from improved pasture levels by 1.7 percent in pounds per year, and by 0.6 percent in milligrams per liter of water. The model simulations predicted a corresponding reduction at the Mill Creek outflow to the Ocklawaha River of 1.3 percent in pounds per year, and 0.5 percent in milligrams per liter of water. These levels are small, but nonetheless support a finding that the berm system is effective in reducing nitrogen from the North Tract. Furthermore, the WAM simulations showed levels of nitrogen from the irrigated pasture after the construction of the retention berms to be reduced from that present in the pre- development condition, a conclusion consistent with that derived from the BMPTRAINS model. The WAM simulations indicated that phosphorus from the irrigated North Tract pastures, measured at the outflow to Mill Creek at the Reach 22 stream segment, would be reduced from improved pasture levels by 3.7 percent in pounds per year, and by 2.6 percent in milligrams per liter of water. The model simulations predicted a corresponding reduction at the Mill Creek outflow to the Ocklawaha River of 2.5 percent in pounds per year, and 1.6 percent in milligrams per liter of water. Those levels are, again, small, but supportive of a finding of no impact from the permitted activities. The WAM simulations showed phosphorus in the Ocklawaha River at the Eureka Station after the construction of the retention berms to be slightly greater than those simulated for the pre-development condition (0.00008 mg/l) -- the only calculated increase. That level is beyond miniscule, with impacts properly characterized as “non- measurable” and “non-detectable.” In any event, total phosphorus remains well below Florida’s nutrient standards. The WAM simulations were conducted based on all of the 15 pivots operating simultaneously at full capacity. That amount is greater than what is allowed under the permit. Thus, according to Dr. Bottcher, the predicted loads are higher than those that would be generated by the permitted allocation, making his estimates “very conservative.” Dr. Bottcher’s testimony is credited. During the course of the final hearing, the accuracy of the model results was questioned based on inaccuracies in rainfall inputs due to the five-mile distance of the property from the nearest rain station. Dr. Bottcher admitted that given the dynamics of summer convection storms, confidence that the rain station rainfall measurements represent specific conditions on the North Tract is limited. However, it remains the best data available. Furthermore, Dr. Bottcher testified that even if specific data points simulated by the model differ from that recorded at the rain station, that same error carries through each of the various scenarios. Thus, for the comparative purpose of the model, the errors get “washed out.” Other testimony regarding purported inaccuracies in the WAM simulations and report were explained as being the result of errors in the parameters used to run alternative simulations or analyze Sleepy Creek’s simulations, including use of soil types that are not representative of the North Tract, and a misunderstanding of dry weight/wet weight loading rates. There was agreement among witnesses that the WAM is regarded, among individuals with expertise in modeling, as an effective tool, and was the appropriate model for use in the ERP application that is the subject of this proceeding. As a result, the undersigned accepts the WAM simulations as being representative of comparative nutrient impacts on receiving surface water bodies resulting from irrigation of the North Tract. The WAM confirmed that the proposed retention berm system will be sufficient to treat additional nutrients that may result from irrigation of the pastures, and supports a finding of reasonable assurance that water quality criteria will be met. With regard to the East Tract, the WAM simulations showed that there would be reductions in nitrogen and phosphorus loading to Daisy Creek from the conversion of the property to irrigated pasture. Those simulations were also conservative because they assumed the maximum number of cattle allowed by the nutrient balance, and did not assume the 30 percent reduction in the number of cattle under the NMP so as to allow existing elevated levels of phosphorus in the soil from the sod farm to be “mined” by vegetation. Pivot 6 The evidence in this case suggests that, unlike the majority of the North Tract, a small area on the western side of the North Tract drains to the west and north. Irrigation Pivot is within that area. Dr. Harper noted that there are some soils in hydrologic soil Group A in the vicinity of Pivot 6 that reflect soils with a deeper water table where rainfall would be expected to infiltrate into the ground. Dr. Kincaid’s particle track analysis suggested that recharge to the surficial aquifer ultimately discharges to Mill Creek, except for recharge at Pivot 11, which is accounted for by evapotranspiration, and recharge at Pivot 6. Dr. Kincaid concluded that approximately 1 percent of the recharge to the surficial aquifer beneath the North Tract found its way into the upper Floridan aquifer. Those particle tracks originated only on the far western side of the property, and implicated only Pivot 6, which is indicative of the flow divide in the Floridan aquifer. Of the 1 percent of particle tracks entering the Floridan aquifer, some ultimately discharged at the St. John’s River, the Ocklawaha River, or Mill Creek. Dr. Kincaid opined, however, that most ultimately found their way to Silver Springs. Given the previous finding that the Floridan aquifer beneath the property is within the Silver Springs springshed for less than a majority of the time, it is found that a correspondingly small fraction of the less than 1 percent of the particle tracks originating on the North Tract, perhaps a few tenths of one percent, can reach Silver Springs. Dr. Bottcher generally agreed that some small percentage of the water from the North Tract may make it to the upper Floridan aquifer, but that amount will be very small. Furthermore, that water reaching the upper Floridan aquifer would have been subject to the protection and treatment afforded by the NMP and the ERP berms. The evidence regarding the somewhat less restrictive confinement of the aquifer around Pivot 6 is not sufficient to rebut the prima facie case that the CUP modification, coupled with the ERP, will meet the District’s permitting standards. Public Interest The primary basis upon which Sleepy Creek relies to demonstrate that the CUP is “consistent with the public interest” is that Florida's economy is highly dependent upon agricultural operations in terms of jobs and economic development, and that there is a necessity of food production. Sleepy Creek could raise cattle on the property using the agriculturally-exempt improved pastures, but the economic return on the investment would be questionable without the increased quality, quantity, and reliability of grass and forage crop production resulting from the proposed irrigation. Sleepy Creek will continue to engage in agricultural activities on its properties if the CUP modification is denied. Although a typical Florida beef operation could be maintained on the property, the investment was based upon having the revenue generation allowed by grass-fed beef production in order to realize a return on its capital investment and to optimize the economic return. If the CUP modification is denied, the existing CUP will continue to allow the extraction of 1.46 mgd for use on the East Tract. The preponderance of the evidence suggests that such a use would have greater impacts on the water levels at Silver Springs, and that the continued use of the East Tract as a less stringently-controlled sod farm would have a greater likelihood of higher nutrient levels, particularly phosphorus levels which are already elevated.

DONE AND ENTERED this 29th day of April, 2015, in Tallahassee, Leon County, Florida. S E. GARY EARLY Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 29th day of April, 2015.
The Issue The ultimate issue for determination is whether the Petitioner has met the requirements of Sections 403.918 and 403.919, Florida Statutes, for the issuance of a dredge and fill permit within the waters of the State of Florida.
Findings Of Fact The Department takes exception to the Hearing Officer's statement in Finding of Fact No. 5 that the fill "over time will become inhabited by the types of life which live at the edge of the water and land." The Department argues that the record contains no competent, substantial evidence to support such a finding of fact. The law prohibits me, as agency head, from rejecting any finding of fact in a recommended order that is supported in the record by competent, substantial evidence, but I can and should reject findings of fact which are not supported in the record by competent, substantial evidence. Section 120.57(1)(b)10., Florida Statutes. In this case I must agree with the exception. A review of the entire record reveals no competent, substantial evidence to support the finding of fact. The only record evidence remotely bearing on the matter is that portion of the testimony of Dr. Peebles where he stated that "there probably are some small animals and little salamanders and whatever that live in that area, but I don't believe that they would all die. I think they migrate out into the other natural area that I'm leaving." (Tr. at 21) 2/ This testimony does not support the finding of fact, and the record contains no other evidence even remotely bearing on the matter. Therefore, I reject this finding of fact and accept the exception of the Department. The Department next takes exception to Finding of Fact No. 11 in which the Hearing Officer states that "However, this effect [on the life cycle of fish] will be minimal and would not itself cause significant damage to fishing or the lake." Once again, the Department contends that there is no competent, substantial evidence in the record to support the finding. Dr. Peebles testified: I can't honestly believe that me filling 14.3 percent, of my frontage is going to effect the health, safety, welfare and property of other people. The same goes for . . . whether the project will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats. Now, this is a case where to argue that on a factual basis would require expert witnesses that would say yes and others that would say no. I think we would find conflicts on all of these subjects. (Tr. at 19) Dr. Peebles also testified that "14.3 percent of the shoreline for the use of the owner is not a serious thing. So I don't think any far reaching serious impacts will occur by granting [the permit]." (Tr. at 75) The only other statement in the record which arguably supports the finding of fact is a statement made by Dr. Peebles while questioning the Department's witness. There Dr. Peebles stated that "I know for a fact -- I'm a fisherman. I fish in the lake. It's a good fishing lake, and with all the construction that's already taken place you've still got good water quality." (Tr. at 70-71) Whether the proposed project and the cumulative impact of reasonably expected future similar projects will have a minimal or significant impact on fishing and the lake is an area requiring specialized knowledge, skill, experience or training. Although the lay opinion of Dr. Peebles may be helpful in supporting expert testimony, lay opinion standing alone may not under law establish what the impacts would be. Dr. Peebles acknowledges that he is not an expert in ecology or the environment, and admits that expert testimony is needed to determine whether granting the permit will adversely affect the conservation of fish and wildlife. (Tr. at 19) Therefore, Dr. Peebles' opinion that there will be no adverse effect on conservation of fish and wildlife (Tr. at 19) and that the filling of "14.3 percent" of the shoreline for the use of the owners will not have "any far reaching serious impacts" (Tr. at 75) is not supported by expert testimony and is not sufficient evidence to support the finding of fact. Section 90.701(2), Florida Statutes; Ehrhardt, Florida Evidence 387 (2d ed. 1984); Husky Industries v. Black, 434 So. 2d 988, 992 (Fla. 4th DCA 1983) ("Expert testimony is not admissible at all unless the witness has expertise in the area in which his opinion is sought.") Furthermore, the statement that Dr. Peebles made while questioning the Department's witness is not evidence. To the extent that it might be liberally construed as evidence in view of the fact that he was not represented by counsel, the existing fishing quality of the lake is not relevant to the impact of future filling of wetlands around the lake. On the other hand, Mr. Jeremy Tyler, accepted as an expert in the areas of the environment and water quality, (Tr. at 52) testified that the cumulative impact of granting Dr. Peebles' permit and similar permits reasonably expected would result in an adverse impact on conservation of fish and wildlife, (Tr. 35-41, 49-51, 54-55) and ultimately would result in a violation of water quality standards. (Tr. at 60, 64 and 69) Therefore, not only is there no competent, substantial evidence in the record to support the finding of fact, but there is uncontroverted expert testimony to the contrary Therefore, I accept this exception. The Department also takes exception to any implication in Finding of Fact No. 11 that the Department's only concern is with cumulative impacts. I do not read the Recommended Order as making any such implied finding. The record shows that the Department concluded that reasonable assurance had been provided that the instant project, standing alone, would not result in water quality violations, (Tyler, Tr. at 51, 60, 64) but that water quality violations will occur and the project is contrary to the public interest when the cumulative impact of reasonably expected future permit applications are taken into consideration. (Tyler, Tr. at 35-41, 49-51, 54-55, 60, 64 and 69) This does not suggest that the Department's only concern in such permitting decisions is cumulative impacts. It only means that under the facts of this application, the only remaining concern is the cumulative impact of reasonably expected future permit applications. The exception is rejected. The Department takes exception to Finding of Fact No. 12 to the extent that the statement "Mitigation of the impacts to fishing is not practical" implies that the only negative impact of the proposed project is to fishing. As noted in my discussion of Point 3 above, the record contains competent, substantial evidence that when the cumulative impacts of reasonably expected future projects are considered, water quality violations will result and the proposed project will be contrary to the public interest. I have reviewed the entire record and find no competent, substantial evidence to support a finding that the impact of the proposed project and cumulative impact of reasonably expected future projects would be limited to fishing quality. To the extent that the Recommended Order implies such a limited impact I reject the implication and accept the exception. The Department's final exception to findings of fact argues that Finding of Fact No. 14 improperly implies that the proposed project would not impair water quality. Finding of Fact No. 14 states, "The amount of fill proposed in this application would not place the lake at risk or impair fishing; however, if additional such permits are approved it may at some point impair the waters and fishing." Although some semantic difficulties arise out of the Hearing Officer's use of the terms "place the waters at risk" and "impair the waters," the finding of fact is consistent with - testimony of Mr. Tyler that reasonable assurance had been provided that this proposed project, standing alone, would not violate water quality standards. (Tr. at 51) The finding is also consistent with the testimony that when the cumulative impact of this project and similar reasonably expected projects are considered, reasonable assurance had not been provided that water quality standards will not be violated and that the project is not contrary to the public interest. (Tr. at 60, 64 and 69) However, the impact of the project on the water quality of the lake is a matter that requires expert testimony. As in the case with the impact on conservation of fish and wildlife discussed above, Dr. Peebles introduced no expert testimony regarding the impact of the project on water quality. On the other hand, the Department's expert witness testified that although reasonable assurance had been provided that the project, standing alone, would not violate water quality standards, (Tyler, Tr. at 51) he also testified that the project by itself would have some adverse impact on water quality. (Tyler, Tr. at 51) Therefore, any implication that the project by itself would not impair the water quality of the lake lacks support in competent, substantial evidence and is contrary to unrebuted expert testimony. To the extent the Hearing Officer's finding implies that the project will not impair water quality, such a finding can not affect the outcome of this case because impairment of water quality is not a proper legal criterion for deciding whether to grant or deny the permit. The proper criterion is whether reasonable assurance has been provided that the project will not violate water quality standards. Cf. Houle v. Department of Environmental Regulation, 10 FALR 3671 (DER Final Order, June 13, 1988), per curiam aff'd, 538 So.2d 1257 (Fla. 1st DCA 1989); Brown v. Dept. of Environmental Regulation, 9 FALR 1871, 1875 (DER Final Order, March 27, 1987), per curiam aff'd, 531 So.2d 173 (Fla. 4th DCA 1988). Since the implied statement of the Hearing Officer does not affect the outcome of this case, any error is harmless and I reject the exception. RULINGS ON EXCEPTIONS TO CONCLUSIONS OF LAW Burden of Proof The Department contends that the Hearing Officer erred in not placing the burden of proof on Mr. Peebles to show that the project is not contrary to the public interest when the cumulative impact of reasonably expected similar future projects are taken into consideration. An applicant for a permit has the burden of proof or persuasion to show entitlement to the permit. Florida Department of Transportation v. J.W.C. Co., 396 So.2d 778 (Fla. 1st DCA 1981). In order to show entitlement to a dredge and fill permit, an applicant must show that he has provided reasonable assurance that water quality standards will not be violated and that the project is not contrary to the public interest, and both of those tests must take into consideration the cumulative impacts of similar projects which are existing, under construction, or reasonably expected in the future. Sections 403.918(1), (2) and 403.919, Florida Statutes; Caloosa Property Owners' Ass'n v. Dept. of Environmental Regulation, 462 So.2d 523 - (Fla. 1st DCA 1985). 3/ The applicant's burden of proof includes the burden of giving reasonable assurance that cumulative impacts do not cause a project to be contrary to the public interest or to violate water quality standards. Concerned Citizens League of America, Inc., v. IMC Fertilizer, Inc., et al., 11 FALR 4237, 4244 (DER Final Order, March 29, 1989); Brown v. Dept. of Environmental Regulation, 9 FALR at 1877. At the hearing, the Department introduced expert testimony that reasonable assurance had not been provided that the project would not cause violations of water quality standards and was not contrary to the public interest when the cumulative impact of reasonably expected future projects were considered. (Tyler, Tr. at 35-41, 49-51, 54-58, 60, 64 and 69) Dr. Peebles, who bore the burden of persuasion, introduced no competent, substantial evidence to show that when cumulative impacts had been considered the necessary reasonable assurances had been provided. 4/ Dr. Peebles argues that his project will only fill in 14.3 percent of his shoreline, and only increase the percentage of the lake's wetlands that have been filled to 31.6 percent from the already existing 30 percent. However, it is not the incremental increase that causes the project to be not permittable, it is the cumulative impact of reasonably expected future projects, and Dr. Peebles failed to carry his burden of persuasion as to the cumulative impacts. Since Dr. Peebles did not carry his burden of persuasion he was not entitled to the permit as a matter of law, and the Hearing Officer erred in concluding that the permit should issue. Therefore, the Department's exception is accepted. Cumulative Impacts The Department takes exception to the Hearing Officer's conclusion of law that: Application of the cumulative effect principle denies the applicant a permit because of the destruction of wetlands by other landowners. The lack of emphasis on enforcement creates a disincentive to comply with the state's regulation of the waters. If those landowners who illegally filled the waters of the state were required to restore the wetlands they destroyed, then new applicants also could fill small portions of wetlands to enhance their use of their property without worrying about cumulative effects. (Recommended Order at 6) At this point it may be helpful to explain the role of cumulative impact analysis. The Department is required to take into consideration the cumulative impacts of similar projects which are existing, under construction, or reasonably expected in the future. Section 403.919, Florida Statutes; Brown v. Department of Environmental Regulation, 9 FALR 1871, 1876 (DER Final Order, March 27, 1987) (cumulative impact analysis is mandatory). Cumulative impact is not a third test, but rather a factor to be considered in determining whether reasonable assurance has been provided that the project will not result in violations of water quality standards and will not be contrary to the public interest. Concerned Citizens League of America, Inc. v. IMC Fertilizer Inc., 11 FALR 4237 (DER Final Order, March 29, 1989). As my predecessor Secretary Tschinkel observed: Without the ability to consider long-term impacts of a project (in combination with similar projects in the area considered "reasonably likely"), DER would be helpless to prevent gradual worsening of water quality and piece-meal elimination of biological resources inflicted by a proliferation of small projects. Morales v. Department of Environmental Regulation, 7 FALR 4786 (DER Final Order, September 18, 1985). The cumulative impact doctrine was originally developed as policy by the Department. It was subsequently codified by the Legislature in 1984 as Section 403.919, Florida Statutes. Chipola Basin Protective Group, Inc. v. Dept. of Environmental Regulation, 11 FALR 467, 476 (DER Final Order, December 29, 1988). - The doctrine was approved by the courts in Caloosa Property Owners Association v. Department of Environmental Regulation, 462 So.2d 523 (Fla. 1st DCA 1985). The cumulative impact statute, Section 403.919, is entitled "Equitable distribution." As the title suggests, the purpose of cumulative impact analysis is to distribute equitably that amount of dredging and filling activity which may be done without resulting in violations of water quality standards and without being contrary to the public interest. In order to determine whether the allocation to a particular applicant is equitable, the determination of the cumulative impacts is based in part on the assumption that reasonably expected similar future applications will also be granted. It does not necessarily follow, however, that all similar future applications must be granted if the current application is granted. Although the Department must be consistent in its permitting decisions to the extent possible and consistent with the public interest, (Rule 17-103.160, Fla. Admin. Code) each future application must stand on its own merit and must provide anew the necessary reasonable assurances subject to cumulative impact analysis. Manasota- 88, Inc, v. Agrico Chemical Co., et al., 90 ER FALR 043 (DER Final Order 1 February 19, 1990). In this case Dr. Peebles argued and the Hearing Officer concluded that the application of cumulative impact analysis is inequitable because previous unpermitted and allegedly illegal filling of wetlands around the lake now results in permits being denied which would have been granted but for the previous filling. There was testimony that about 30 percent of the original wetlands around the lake had been filled in the past, (Tyler, Tr. at 67) that all of the past filling was unpermitted, and that some of it may have been illegal. (Tyler, Tr. at 46, 61-62, 66-67, 72) However, the record contains no competent, substantial evidence showing how much, if any, previous filling was illegal. Furthermore, Section 403.919(2) requires the Department to consider the impacts of "projects which are existing", and does not draw a distinction between legal or illegal projects. As to the Hearing Officer's recommendation that cumulative impacts not be considered in this application, I note that Section 403.919, Florida Statutes mandates that such an analysis be conducted for every dredge and fill permit. Section 403.919 states that "The department in deciding whether to grant or deny a [dredge and fill] permit for an activity which will affect waters, shall consider [cumulative impacts]." See also Brown, supra, 9 FALR at 1876 (cumulative impact analysis is mandatory). Therefore, to the extent that the Hearing Officer is recommending cumulative impact analysis not be applied to Dr. Peebles' application, the recommendation is contrary to the law and must be rejected. The issue then remains of how past fill, whether legal or illegal, should be considered in the cumulative impact analysis. The Hearing Officer's recommendation in effect would require the Department to conduct a cumulative impact analysis under the assumption that previously filled wetlands should be treated as functioning wetlands. If I were to accept this view it would require the Department to take enforcement action in every case or abandon the protection of water quality of certain waters of the state. Such an interpretation would strip from the Department's hands the ability to exercise its discretion in allocating its limited enforcement resources, and result in the Department's enforcement priorities being set by permit applicants rather than by the Department. I note that the record contains competent, substantial evidence that the Department lacks sufficient resources to enforce every violation, (Tyler, Tr. at 45) although such a fact scarcely needs proof. Acceptance of the Hearing Qfficer's recommendation would place the Department in the dilemma of having to choose to withdraw enforcement resources from more environmentally significant projects or to abandon altogether the protection of less significant projects. Acceptance of the Hearing Officer's conclusion of law would also result in requiring the Department in all cases to determine whether violations had occurred and to take enforcement action for prior violations before it could consider cumulative impacts. Aside from the lack of sufficient enforcement resources, such enforcement' proceedings seldom, if ever, could be commenced and completed within the 90 days within which the Department must act on an application. Section 403.0876, Florida Statutes. The result would in effect limit the scope of Section 403.919 to pristine water bodies, and render the statute largely meaningless. I cannot accept that the Legislature intended such interpretations of Section 403.919, Florida Statutes. Although the result of the application of cumulative impact analysis to the facts of this case may seem harsh, the record indicates that Dr. Peebles may still obtain access the waters of the lake by means of a private dock that would not even require a permit if it had 1000 square feet or less of surface area and met the other provisions of Rule 17-312.050(1)(d), Fla. Admin. Code. Dr. Peebles' existing planned dock is 452 square feet. Therefore, Dr. Peebles could extend that portion of the dock that bridges the wetlands to the uplands by an additional 548 square feet of surface area. For example, the four foot wide bridge to the dock could be extended an additional 137 feet, which is more than enough to reach the upland portion of the lot. (Joint Exhibit No. 1) For the reasons state above, I reject the Hearing Officer's conclusion of law and accept the exception. Public Interest Test The Department also takes exception to the Hearing Officer's conclusion that the project is not contrary to the public interest. In conducting the public interest test the Department must balance the criteria as specified by the Legislature. Section 403.918(2)(a) states: In determining whether a project is not contrary to the public interest, or is clearly in the public interest, the department shall consider and balance the following criteria: Whether the project will adversely affect the public health, safety, or welfare or the property of others; Whether the project will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; Whether the project will adversely affect navigation or the flow of water or cause harmful erosion or shoaling; Whether the project will adversely affect the fishing or recreational values or marine productivity in the vicinity of the project; Whether the project will be of a temporary or permanent nature; Whether the project will adversely affect or will enhance significant historical and archaeological resources under the provisions of 5.267.061; and The current condition and relative value of functions being performed by areas affected by the proposed activity. The Department introduced evidence that criteria 1, 3 and 6 were neutral, (Tyler, Tr. at 54-56) that criteria 2, 4, 5 and 7 were negative, (Tyler, Tr. at 35-36, 54, 56, 57) and that when all the criteria were balanced there was a negative value to the project. (Tyler, Tr. at 57-58) Dr. Peebles argued at the hearing and in his response to exceptions that the Department's methodology in weighing each criteria in the public interest balancing test is incorrect. I disagree, and note that Dr. Peebles bore the burden of proof on the public interest test, and was free to introduce competent, substantial evidence on each criteria. As discussed in Part II above, Dr. Peebles did not introduce any competent, substantial evidence as to any of the above. The Hearing Officer's conclusion of law lacks competent, substantial evidence to support it, and is contrary to unrebuted competent, substantial evidence. Therefore, I reject this conclusion of law.
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 Petitioner to place fill in the waters of the state be approved in accordance with the drawings submitted with the application.

Findings Of Fact On April 2, 1981, Lee County applied to DER for a permit to construct an extension of Colonial Boulevard east to State Road 82B by dredging 4,600 cubic yards of material landward of the ordinary high water mark, and by depositing 83,000 cubic yards of fill landward of the ordinary high water mark in an area of Lee County known as the Six Mile Cypress Strand or Six Mile Cypress Slough. The permit application was made by Lee County on standard DER forms which would have been appropriate for an application under either or both Chapters 253 or 403, Florida Statutes. Additionally, Lee County tendered a permit application fee to DER sufficient to cover the cost of an application under both statutes. After review of the application, DER determined that it had no jurisdiction under Chapter 253, Florida Statutes, and refunded to Lee County that portion of the permit application fee required for a Chapter 253 permit. As indicated above, Lee County's application, on its face, reflected that no fill material or dredging was proposed waterward of the ordinary high water mark. The Six Mile Cypress Strand is a meandering swamp, approximately 44,000 acres in size, dominated by cypress trees. At periods of high water the waters of the swamp empty into Ten Mile Canal, an artificial water body which connects to Estero Bay by way of Mullock Creek, a natural stream. All water bodies involved in this proceeding are classified as Class III waters. Six Mile Cypress Strand functions as a major aquifer recharge area for the eastern central portion of Lee County. The area drained by the Strand receives approximately 54 inches of rainfall annually. The wetland vegetation and uneven contours of the Strand allow the assimilation of nutrients and reduction in turbidity and erosion which could otherwise adversely affect downstream waters. The drainage area north of the proposed project consists of approximately 5,000 acres, or 11 percent of the total drainage basin served by the Strand. The proposed roadway would cross the Strand through a corridor which contains three cypress heads, or flag ponds. These ponds generally retain water during dry periods and support a more diverse community of aquatic life than those portions of the Strand which become completely dry. At the time of final hearing in this cause, these ponds exhibited dry season characteristics and contained less than one foot of water in their deepest portions. During low water periods the Strand itself may be virtually dry except for standing water in the vicinity of cypress heads and flag ponds. Only during the rainy season, which occurs during approximately four months of the year, does the Strand contain standing water. During high water periods, however, water may flow continuously throughout the length of the Strand. During these latter periods, canoes and other such small water craft may be able to negotiate portions of the Strand. No evidence was presented, however, which would indicate that the Strand is now or has ever been utilized, or is susceptible to utilization, for commercial boat traffic. The lands in the Strand over which Lee County proposes to build the roadway were conveyed by the Trustees of the Internal Improvement Trust Fund to private ownership after having been acquired from the federal government under the Swamp and Overflow Grant Act of 1850. The Strand was not meandered in the original government survey of the area, and, in fact, the surveyor's field notes reflect that the area of the Strand was densely vegetated and crossed by several roads, including one crossing the section line in the same vicinity proposed for the Colonial Boulevard extension. The existence of this last referenced road is corroborated by biological evidence presently existing on the site, and from examinations of full infrared aerial photography of the area. It is approximately nine miles from the Strand to the nearest meander line contained in the original government survey. Further, evidence of record in this proceeding establishes that water craft may not presently be navigated from Estero Bay into the Strand because of man-made barriers, and no record evidence establishes that such navigation would have been possible at the time of Florida's admission to statehood in 1845 when the stream presumably was in its natural condition. The Department of Natural Resources was notified in accordance with DER policy, of the pendency of Lee County's application, and asserted no claim of ownership over sovereignty lands in the area of the proposed project. The design for the proposed roadway includes a system of collector and spreader swales on the upstream and downstream sides of the Strand, respectively, connected by large culverts to be located beneath the roadway. The swales and culverts are intended to minimize interruption of the Strand's hydroperiod, the natural fluctuation and flow of waters within the affected portion of the Strand. A vegetated swale system paralleling the roadway is also included in the proposed roadway design to provide treatment and nutrient uptake from storm water runoff generated from the surface of the roadway. In addition, the toe of the slope of the roadway will be replanted with native vegetation, and the edge of the fill area will be meandered to save some existing vegetation. It is anticipated that the roadway could result in runoff containing from .17 to .18 pounds per day of nitrogen, and from .01 to .07 pounds per day of phosphate. The grassy swales proposed for inclusion in the project design have the capability of assimilating from 1.8 to 3.6 pounds of these nutrients per day, thereby ensuring a significant safety factor. It can also reasonably be anticipated that the swale areas are capable of absorbing any BOD loading from the roadway surface. As a result, it can reasonably be anticipated that the construction of the project will not result in the discharge of nutrients into the Strand, and that any heavy metals will be bound in organic sediments and not result in degradation of existing water quality. Ambient water conditions in the Strand show low dissolved oxygen content together with high biochemical oxygen demand, neither of which should be exacerbated by construction of the project. No violation of water quality criteria relating to herbicides is anticipated in view of Lee County's commitment at final hearing in this cause to control vegetation by way of mowing instead of by the use of herbicides. The proposed construction will, of course, destroy aquatic vegetation in the area lying in the path or "footprint" of the roadway itself, consisting of approximately seven and one-half acres, three acres of which are predominantly cypress. However, because of the design features of the proposed roadway, including grass, collector and spreader swales and the culvert system, the anticipated impact on the hydroperiod upstream and downstream of the project, and thereby the effect on aquatic vegetation and water quality will not be significant. Construction fabric will be used to allow the road surface to be supported without demucking, thus minimizing turbidity during construction periods, although it is intended that construction be conducted during the dry season, thereby further reducing the potential for turbidity violations. Further, the detention swales which are to be equipped with French drains are designed to retain the first inch of rainfall. Culverts to be constructed on the roadway are designed to accommodate a 50-year, 24-hour storm event. The Secretary of DER issued the subject permit on August 18, 1981, without any prior notice of intent. ASSWF received notice of DER's action in the form of a complete copy of the permit on August 27, 1981. On September 2, 1981, ASSWF filed its petition requesting a formal Section 120.57(1), Florida Statutes, hearing. This petition was received by DER on September 8, 1981. ASSWF and Audubon, and the members of these organizations, use the Six Mile Cypress Strand in the vicinity of the proposed project for field trips and environmental education activities which will be impacted should the project be approved. In addition, Audubon owns property within the Strand which may also be affected by the proposed project if permitted. Intervenors, Community Council and Lehigh Acres of Florida, Inc., Ralph Marciano, Claudia Tipton and H. Mark Strong requested to be granted party status in this proceeding in support of the application. Ralph Marciano owns a business allegedly limited because of the present poor highway access to the business center of the city. Claudia Tipton owns an electrical construction business alleged to be seriously hampered because of extended transportation time in emergency trips. H. Mark Strong is a retired fire marshal and contends that paramedics are seriously hampered in transporting emergency patients to the community hospital located in Fort Myers. The Community Council of Lehigh Acres was formed to serve as a council representing the entire community of Lehigh Acres on problems and projects affecting the health, welfare, growth and prosperity of Lehigh Acres. Essentially, these intervenors assert that the general public welfare and, in some cases, their own personal business interests, will be enhanced by building the proposed roadway, thereby enhancing vehicular access to various portions of the community.
