The Issue The issue in this case is whether the portion of Consumptive Use Permit (CUP) Application Number 97106 seeking an allocation of 499,000 gallons per day (gpd) of groundwater for commercial/industrial uses (supply bulk water to bottling plants) meets the conditions for issuance as established in Section 373.223, Florida Statutes, Florida Administrative Code Rule 40C-2.301, and the Applicant’s Handbook, Consumptive Uses of Water.1 The County does not oppose or contest the portion of the CUP application authorizing use of 6.0 million gpd of surface water for limerock mining operations.
Findings Of Fact The Parties The County is a political subdivision of the State of Florida. The County operates a water supply utility that supplies water for a variety of uses, including providing untreated water, in bulk, for bottling purposes. The County is currently engaged in a long-range planning effort designed to assess water supply demands and sources to supply those demands in the County over the next 50 years. The County also has completed a study of the two major springs in the County (Rainbow Springs and Silver Springs), and the County’s Board of County Commissioners is in the process of enacting certain recommendations contained in the study. The well for the proposed CUP allocation is located on approximately 160 acres in northern Marion County. Hastings and Greene's father owned the property from 1978 until the latter's death. In 1993, the latter's interest was transferred to Greene and two brothers, who now hold title to the property along with Hastings. The District is a special taxing district created by Chapter 373, Florida Statutes, and is charged with the duty to prevent harm to water resources of the District, and to administer and enforce Chapter 373, Florida Statutes, and the rules promulgated thereunder. The District has implemented Chapter 373, Florida Statutes, in part, through the adoption of Rule Chapters 40C-2 and 40C-20, and the Applicant’s Handbook, Consumptive Uses of Water. Historic Uses of Water on the Mine Site Since the 1980s, the property where the proposed withdrawals will occur has been used for mining of limerock and has been known as the “Black Sink Mine." A ten-inch diameter well has been located on the Black Sink Mine property for 35 years. The well was originally used to provide water to augment water levels in canals in and around the Black Sink Mine property. Later the well was used to irrigate watermelons grown on the property before the mining operation began. The limerock mining operation at Black Sink Mine uses approximately 6 million gpd of surface water. The mine pit at the site is divided by an earthen berm that separates a larger, previously mined area from a smaller area where active mining is occurring. Surface water is pumped from the actively mined portion of the pit to the larger, previously mined portion of the pit, to enable mining of the limerock material to be conducted at levels below the water table. Dewatering is necessary in order to remove the limerock. A majority of the property is mined to a depth of 55 feet below land surface. The limerock material extracted from the site is transported by trucks from the site, approximately 100 trucks per day, to various sites across North Florida. The Need for the Proposed Use of Groundwater If mining of limerock continues at the current pace, the limerock material at the Black Sink Mine will be exhausted within a year. Recognizing that the productive use of the property for limerock mining was nearing an end, Greene and Hastings began exploring other potential uses for the property, including use of the existing well on the property for production of bottled water. To explore the feasibility of producing water for bottling from the existing well, in 2004 Greene and Hastings engaged an engineering firm with expertise in water resources to conduct a hydrogeologic study of the mine property and well. The results of the study, showing water of sufficient quality and quantity for production of bottled water, motivated Greene and Hastings to submit the CUP application which was the subject of the hearing. The study also determined that water withdrawn from the well could be marketed as spring water. Greene and Hastings also determined through market research that the demand for bottled water has increased at the rate of ten percent per year for the last 4-5 years and that Florida bottlers were interested in purchasing water from the well on the mine site in bulk for bottling. In order to provide reasonable assurance that the water use proposed by Greene and Hastings is in such quantity as is necessary for economic and efficient utilization, Greene and Hastings must show that the amount to be used is consistent with what would typically be required for the activity being supplied; that the water will be used efficiently with loss or waste minimized; and that there is a demonstrated need for the water proposed for allocation. To demonstrate a need for the 499,000 gpd of groundwater requested in the application for an allocation of 499,000 gpd of groundwater, Greene and Hastings provided letters from two businesses engaged in bottling of water stating an intent to purchase specific quantities of water produced from the Greene and Hastings well should the CUP be granted. One of the letters of intent came from a bottler in Jacksonville, Florida, stating its intention to initially purchase 100,000 gpd of Greene and Hastings’s water. The other was from a bottler in Stuart, Florida, dated January 9, 2006, stating its intention to purchase 125,000 gpd of water from Greene and Hastings within “the next 12-24 months.” Based on these letters Greene and Hastings initially requested an allocation of 200,000 gpd of groundwater for the first year of the permit. Prior to completion of the CUP application, Greene and Hastings learned that because the Stuart bottler’s facility was located outside the geographic boundaries of the District, to transport water from the Black Sink Mine to the Stuart facility would require additional data and information related to inter- district transfers of groundwater. Greene and Hastings elected to reduce the requested allocation for the first year of the permit to 100,000 gpd, relying on the letter from the Jacksonville bottler. Based on the current market demand for bottled water, and based on the fact that there are other bottlers of water within the boundaries of the District purchasing water for bottling, it is reasonable to conclude that Greene and Hastings can sell 499,000 gpd of water from the well on the Black Sink Mine property by the end of the fifth year of the proposed CUP. These facts support the conclusion that there is a need for the amount of water requested by Greene and Hastings. In addition, the permit is conditioned to require a compliance review at five-year intervals during the term of the permit. Should Greene and Hastings not be successful in selling the full 499,000 gpd allocated by the fifth year of the permit, the District has the ability as part of the five-year compliance review to modify the permit to reduce the allocation based on the amount of water actually used for bottled water. Efficiency of the Proposed Use of Water The production of water in bulk for shipment to a bottler is a highly efficient use of water. There is very little if any water lost in the withdrawal and loading of the water; almost all the water goes to the end product. The evidence establishes that the use proposed by Greene and Hastings is an efficient use of water. Potential Impacts from the Proposed Groundwater Allocation The source of the groundwater proposed for use by Greene and Hastings is the Floridan aquifer. Because there is no confining layer in the vicinity of the Black Sink Mine that would retard movement of water between the Upper Floridan aquifer and the surficial aquifer, both the Upper Floridan aquifer and the surficial aquifer essentially behave as one unit. Thus, any drawdown in the surficial aquifer associated with groundwater withdrawals at this location will be the same as the related drawdown in the Upper Floridan aquifer as a result of groundwater withdrawals. The Floridan aquifer is capable of producing the amount of groundwater requested by Greene and Hastings in the application. To assess the level of drawdown expected to occur in both the Floridan aquifer and the surficial aquifer as a consequence of the proposed groundwater withdrawals, Greene and Hastings engaged a consultant, Andreyev Engineering, Inc., to run a groundwater model to simulate the proposed withdrawal and predict the anticipated drawdown. The groundwater model selected for use for this application was the North Central Florida Regional Groundwater Flow Model, a model developed for the District by the University of Florida for use in Marion County and surrounding areas. This model is an accepted and reliable tool for predicting aquifer drawdown associated with groundwater withdrawals at the location of the withdrawals proposed in this application and is used extensively by the District in its CUP program. To simulate the drawdown associated with the withdrawal of 499,000 gpd from the Florida aquifer, Greene and Hastings’s consultant inserted a pumping well in the model grid where the Black Sink Mine is located. The model then simulated pumping from the well at 499,000 gpd. The model results are graphically depicted on maps showing drawdown contours overlain on the Black Sink Mine Site, illustrating the level of drawdown in the aquifer and the distance the level of drawdown extends out from the well site. The model predicts a drawdown of 0.03 feet in the Floridan and surficial aquifers in the immediate vicinity of the well on the Black Sink Mine property, and a drawdown of 0.02 feet in the Floridan and surficial aquifers extending out to a distance of approximately 5,000 feet from the well, less than 1/3 of an inch of drawdown. The model results represent a reasonable estimation of the drawdown that will occur as a consequence of withdrawal of 499,000 gpd of groundwater at the Black Sink Mine as proposed in the application. The impact of the 0.02-0.03 foot drawdown predicted by the model was variously characterized by the experts who testified at the final hearing as “not practically measurable,” an “insignificant impact,” “very small,” or “de minimus.” The use of water proposed by Greene and Hastings will not cause significant saline water intrusion, nor will it further aggravate any existing saline water intrusion problems. The use of water proposed by Greene and Hastings will not induce significant saline water intrusion to such an extent as to be inconsistent with the public interest. Because the predicted drawdown is so small, it will not interfere with any existing legal uses of water. Neither will the predicted drawdown cause serious harm to the quality of the source of the water proposed for use by Greene and Hastings. With regard to the issue of interference with existing legal users, the County argued that the District should have considered whether there is sufficient groundwater available to meet all projected needs for water in the County during the 20- year term of the permit, as well as the additional cost County citizens will need to bear to secure alternative water supplies as a result of any future shortfalls in available groundwater. The County projects, based on planning estimates, that use of groundwater to supply all anticipated uses of water in the County will be limited within 20-30 years from the present. Such “limits” would not become an issue until after the Greene and Hastings permit expires. Thereafter, water users in the County will have to rely on alternative water sources, conservation, reuse of reclaimed water, and surface water. The anticipated growth in demand in the County’s planning estimates includes anticipated growth in the commercial/industrial category of uses. The County’s estimated limits on groundwater use will occur whether or not the CUP requested by Greene and Hastings is approved. The District does not base its permitting decisions on a pending CUP application on the possibility that the source of water may become limited at some future time for water uses not presently permitted, provided the application meets all permitting criteria. The District allocates water for recognized beneficial uses of water, such as commercial/industrial uses, as long as the water is available and the application meets District criteria. The District allocates water as long as an allocation does not cause harm to the resource. Based on these facts, the proposed use of water by Greene and Hastings will not interfere with any existing legal use of water. No Evidence of Economic or Environmental Harm Because the predicted drawdown associated with the proposed use of water is so small, and because no impacts are anticipated on any surrounding properties or water uses, Greene and Hastings have provided reasonable assurance that any economic harm caused by the proposed use has been reduced to an acceptable amount. For purposes of determining whether an applicant has provided reasonable assurance that any environmental harm caused by a proposed use of water is reduced to an acceptable amount, the District examines modeling results showing the level of drawdown predicted for the use and also examines the resources in and around the site of a withdrawal to determine the likely impact of the drawdown predicted for the withdrawal on those resources. The District’s environmental scientists examined the Black Sink Mine site and the surrounding landscape and determined that, based on the characteristics of the landscape in and around the site of the proposed withdrawal and based on the negligible drawdown impact predicted for the proposed water use in both the Floridan and surficial aquifers, there will be no environmental harm resulting from the allocation of groundwater contained in the CUP. The use of water proposed by Greene and Hastings will not cause damage to crops, wetlands, or other types of vegetation. The use of water proposed by Greene and Hastings will not cause the water table to be lowered so that stages or vegetation will be adversely and significantly affected on lands other than those owned, leased, or otherwise controlled by Greene and Hastings. The CUP will not use water that the District has reserved pursuant to Section 373.223(3), Florida Statutes, and Rule 40C-2.301(4). No Impact on Established Minimum Flows or Levels No minimum surface or groundwater levels or surface water flows have been established by the District pursuant to Rule Chapter 40C-8 for any of the water bodies in Marion County that may be affected by the proposed water use. The closest water body for which the District has established a minimum flow is the St. Johns River at the State Road 44 bridge located more than 50 miles from the Black Sink Mine property. The closest water body for which the District has established a minimum level is Star Lake in Northwest Putnam County, more than nine miles from the mine site. Because of the distance of these water bodies from the withdrawal site and because of the negligible drawdown expected to be caused by the proposed use of water, the use will not cause an established minimum flow or level to be exceeded during the term of the permit. Other Reasonable-Beneficial Use Considerations All available conservation measures that are economically, environmentally, and technically feasible are proposed for implementation in the application by Greene and Hastings for the uses proposed by them. Greene and Hastings submitted to the District, as part of the application, a conservation plan that complies with the requirements of A.H. Section 10.3(e). Reclaimed water, as defined in the District’s rules, is not currently available to be used in place of the water proposed for use by Greene and Hastings in the application. The use of water proposed by Greene and Hastings in the application will not cause or contribute to a violation of water quality standards in receiving waters of the state. The use of water proposed by Greene and Hastings in the application will not cause or contribute to flood damage. The Use is Consistent With the Public Interest With regard to the determination of whether reasonable assurance was provided that the proposed use is consistent with the public interest, the County contends that: 1) Greene and Hastings must show that any necessary approvals required by the County’s Comprehensive Plan and/or its LDRs for use of the site for producing bottled water have been obtained; 2) that the District did not properly consider the effect of existence of lawn watering restrictions affecting citizens in the County in evaluating the application; and 3) that the District should have considered the amount of money the applicant may stand to gain from the use of the water requested in the application. In examining whether an application is consistent with the public interest, the District considers whether a particular use of water is going to be beneficial or detrimental to the people of the area and to water resources within the state. In this inquiry, the District considers whether the use of water is efficient, whether there is a need for the water requested, and whether the use is for a legitimate purpose; and the inquiry focuses on the impact of the use on water resources and existing legal users. Sale of water for bottling for human consumption is recognized by the District as a legitimate, beneficial economic enterprise. Use of water for human consumption is among the highest and best uses permitted by the District. For reasons outlined above in the Recommended Order, there are no detrimental impacts that will result from this use of water. The District does not consider whether local government approvals have been obtained prior to issuance of a CUP for purposes of determining whether the application is consistent with the public interest. Neither does the District consider impacts related to local roads from trucks transporting the water or other impacts not related to water resources. No such requirements are included in the District’s adopted permitting criteria. There are no water shortage orders in effect in the District at present. In evaluating a CUP application, the District considers whether its permitting criteria will be met during periods of normal weather as well as during periods of drought. Withdrawals authorized in CUPs can be restricted by order of the District during periods of water shortage, such as droughts. Thus, the possibility of a water shortage order being entered in the County in the future, or the fact that such orders may have been in effect there in the past, does not mean the application is not consistent with the public interest. The District critically examines the efficiency of all water uses for purposes of enacting its regulatory requirements regarding CUPs and in evaluating CUP applications. The District has adopted restrictions on landscape irrigation (which apply to all such users throughout the District’s jurisdiction, not just in Marion County) limiting landscape irrigation to no more than two days per week. The limitations on landscape irrigation exist because this type of use has been determined to be a highly inefficient, wasteful use of water without such restrictions. By contrast, the use of water proposed by Greene and Hastings is a highly efficient use of water, resulting in little or no loss or waste of water. The District does not consider the level of financial gain or benefit an applicant will derive from a permitted use of water for purposes of determining whether the proposed use is consistent with the public interest. Most, if not all permitted users of water derive some level of economic benefit from the water they use, and the District’s rule criteria do not provide standards for evaluating such gain or that otherwise limit the amount of such gain. For the foregoing reasons, the Applicant has provided reasonable assurance that the use of water proposed in the application is consistent with the public interest. Groundwater is the Lowest Quality Source for this Use The County contends that groundwater is not the lowest quality source of water available for the use proposed by Greene and Hastings, in that surface water from the mine pit on the site could be treated and used for bottling in place of groundwater. From the testimony, it is clear that Greene and Hastings’s ability to market water for bottling from the Black Sink Mine is dependent on such water being capable of being labeled as spring water, and on such water being delivered without having gone through any treatment processes. The testimony also establishes that because of the connection between the surficial aquifer and the Upper Floridan aquifer at the site, using surface water instead of groundwater to supply the proposed use would result in little if any reduction in impacts to the Floridan aquifer. More importantly, because the application proposes use of water for direct human consumption, the District’s rules do not require use of a lower quality source of water. For the foregoing reasons, groundwater is the lowest quality source of water suitable for use for bottled water for human consumption. The District’s Noticing Was Adequate and Appropriate The District provided notice of its receipt of the Greene and Hastings CUP application by publishing notice in the Ocala Star-Banner, a newspaper of general circulation in Marion County, on January 25, 2005, with an amended notice being published on February 16, 2005, and also by letters to the County dated January 20, 2005, and February 10, 2005. In each notice, the location of the proposed use was identified by section, township, and range. The County responded to the notices by sending a letter of objection to the application dated February 14, 2005. Thus, the County received sufficient information regarding the location of the proposed use to enable it to prepare and file a letter of objection to the application, and suffered no prejudice as a consequence of the notice. The District provided personal notice of its intent to issue a CUP to Greene and Hastings by letter dated April 5, 2006. In this notice, the location of the proposed use was identified by section, township, and range. The County responded by filing petitions that have resulted in this proceeding. Thus, the County received sufficient notice of the location of the use addressed in the District’s intent to issue to enable it to initiate administrative proceedings regarding the permit, and suffered no prejudice as a consequence of the notice.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the District enter an order granting CUP No. 97106 to Greene and Hastings with the conditions recommended in the District’s Technical Staff Report.

The Issue The issue in this case is whether the development order issued by Polk County for Robert Crowder's development known as Paradise Country Estates complies with Chapter 380, Fla. Stat. (1991). The Department of Community Affairs' Petition for Appeal of Development Order (the DCA Petition) alleges that the development order is contrary to Polk County's 1985 comprehensive plan for the following reasons: Paragraph 11 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 9, Objective III, "Natural Resources," of the Land Use Element (LUE) of the 1985 Plan. Policy 9 states: "Structures should be placed in a manner which will not adversely affect the natural flow regime and which will not reduce the recharge capabilities." Paragraph 12 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 10, Objective III, "Natural Resources," of the LUE. Policy 10 states: "Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973." Paragraph 13 of the DCA Petition alleges that the development order is contrary to the provisions of Policy 11, Objective III, "Natural Resources," of the LUE and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element of the Plan. Respectively, these policies state: 11. Groundwater withdrawal should not exceed the safe yield per acre as determined by Water Management Districts or successor agencies. * * * Minimize the adverse impacts of development on resources of the Floridan Aquifer, wetlands and flood-detention areas. Protect the normal quantity, quality and flow of ground water and surface water which are necessary for the protection of resources of state and regional concern. Paragraph 14 of the DCA Petition alleges that the development order is contrary to a section of Part II of the Conservation Element of the Polk County Comprehensive Plan entitled "Rare and Unique Natural Resources," which describes the Green Swamp as a "rare and unique land area resource for conservation consideration" and also states: The potentiometric high of the Floridan Aquifer lies within this area. . . . The area has a high potential for recreational and natural enjoyment. . . . The Green Swamp area is the largest expanse of forest in Polk County, with abundant water and wooded areas to provide for wildlife habitats. This area has great significance as an area for conservation of land, air, water, open space and wildlife habitats. Paragraph 15 of the DCA Petition alleges that the development order is contrary to the following section on "Density" found in Part IV of the Conservation Element, entitled "Summary of Special Problems, Areas, Issues, and Relationships": The subject of development density is a particular issue of vital importance to the county. Low density development in some areas and high density in other areas is important so that demands for public facilities can be economically and efficiently handled, so that environmental degradation is minimized, and so that land, not suitable for development, can be saved for important natural functions. The present zoning ordinance classifies most of the county in a Rural Conservation (RC) classification that permits low density development without proper regard for those areas that are best suited for development. Portions of the county should be protected from development pressures and appropriate areas should be zoned to accommodate rational densities. The present level of protection, provided by the zoning system is not brought to bear for conservation purposes. Paragraph 16 of the DCA Petition alleges that the development order is contrary to Policy 14 of the "Water Resource Objective" of the Conservation Element of the Plan: "Protect or improve existing ground and surface-water quality." Paragraph 17 of the DCA Petition alleges that the development order is contrary to Policy 2, Objective I, "Agricultural Uses," in Part V of the LUE: Protect, to the maximum extent possible, agricultural lands from encroachment of incompatible land uses and any detrimental effects of development adjacent to agricultural areas. Paragraph 19 1/ of the DCA Petition alleges that the development order is contrary to Policy 2, Objective IV, "Residential Uses," in Part V of the LUE: Promote and encourage new residential development adjacent to established growth centers, to ensure the orderly use of land and the efficient provision of facilities and services. Paragraph 20 of the DCA Petition alleges that the development order is contrary to Section 5-1(6) of Polk County Ordinance 81-28 (the County Flood Protection and Surface Water Management Code). 2/ Article V is entitled "Flood Protection Standards." Section 5-1 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to new construction and substantial improvements in all areas of special flood hazard, and to any development, other than phosphate mining, within 100 feet of a watercourse: * * * (6) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. Paragraph 21 of the DCA Petition alleges that the development order is contrary to Section 5-2(4) of Polk County Ordinance 81-28. 3/ Section 5-2 provides in pertinent part: SPECIFIC STANDARDS: The following minimum standards shall apply in all areas of special flood hazard where base flood elevation data has been provided: * * * Subdivision Proposals: All subdivision proposals and other proposed developments shall be reviewed by the County Engineer. [I]f the proposal is in an area of special flood hazard, it shall be reviewed to assure that the following standards are met: All such proposals shall be reasonably safe from flood waters resulting from the base flood. All such proposals shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize flood damage. Base flood elevation data shall be provided for all such proposals. Roads shall be reasonably safe from flood waters resulting from the base flood. Paragraph 22 of the DCA Petition alleges that the development order is contrary to Section 6-2(3)(a) of Polk County Ordinance 81-28. Article VI of Polk County's Flood Protection and Surface Water Management Code is entitled "Water Management Standards." Section 6-2 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to all development which occurs within an area of special flood hazard and to any man-made change to improved or unimproved real estate . . .. * * * (3) (a) The amount of site alteration within a wetlands soil association shall be limited to ten percent (10%) of the area of wetlands soil association within any given total site.
Findings Of Fact The Proposed Project and Location. The project site is on Dean Still Road in Polk County, approximately 2 miles west of State Road 33. It is approximately 6 and 1/2 miles from Polk City and 15 miles from the City of Lakeland. The proposed project is comprised of 356 lots on approximately 1280 acres with a gross density of 1 unit per 3.6 acres. Although the average lot size varies, the project was reviewed under the Southwest Florida Water Management District's (SWFWMD) criteria for rural development which requires that at least 90% of the lots be at least 2 acres in size (excluding jurisdictional wetlands), and 10% of the lots be at least 1 acre (excluding jurisdictional wetlands). The site has been zoned Rural Conservation under Polk County's Zoning Code for approximately 12 years. This designation allows a density up to 1 unit per acre. Individual water wells and on-site waste disposal systems (septic tanks) will be utilized for each home. There are no water or sewer extensions proposed for the site or for adjacent areas by any governmental entity. Access to the site from Polk City is along Dean Still Road, which is unpaved at this time. The County has plans to pave it in the near future. Of the 1280 acres comprising the project site, 362 acres have been claimed as jurisdictional wetlands and approximately 642 acres have been mapped within the 100-year floodplain by the Federal Emergency Management Agency (FEMA). 51 of the lots platted in the project are entirely within the FEMA 100- year flood plain. Several other lots contain large portions within FEMA 100- year flood plain. Despite the significant amount of wetlands and floodplains on the site, the project is designed so that no net loss will occur in the floodplains and less than 1% (.59%) of the jurisdictional wetlands will be impacted by development. Impervious conditions on the site will only increase by 2.8% after development. All structures will be set at or above the 100 year flood elevation, as calculated by the project engineers, and will be constructed in accordance with the County's flood protection standards. The project is designed so that post-development runoff is less than pre-development runoff and post-development drainage basins conform to pre-development drainage basins. Existing drainage patterns for the site are designed to be maintained. The property comprising the project has been used through the years for a variety agricultural purposes, including harvesting watermelons, soybeans, corn, and silage. It has been drained and ditched to facilitate these activities. It is currently being used for grazing cattle. A sod farm is located to the south of the property. Additional cattle grazing lands run south from there to Polk City. To the north of the site are ranchlands which run to the border of the Withlacoochee Wildlife Area. Immediately to the west of the site are 20-30 scattered mobile homes and additional ranchlands in a subdivision known as Evans Acres. This subdivision was initially approved by DCA in 1983, and was comprised of 48 lots on approximately 1,290 acres. The original lots ranged in size from 5 to 60 acres. Apparently, individuals have since split their lots and many of the existing lots are 2 to 5 acres in size. A few of the original lots are used for both residential and ranching purposes. Including the large and small lots, there are approximately 163 lots on the property comprising Evans Acres. On the property directly to the east of the site are approximately 16 mobile homes along Melody Lane. These existing homesite numbers are small and scattered when compared to the 356 lots proposed for Paradise Country Estates. Approximately 120 families live in the general vicinity of the proposed project. The Green Swamp. The project is within the Green Swamp Area of Critical State Concern (ACSC). The site is within the drainage basin of the Withlacoochee River, which has been designated an Outstanding Florida Water (OFW) and is approximately three and a half miles to the north. The Green Swamp ACSC was designated by the Legislature. Chapter 79- 73, 380.0551, Florida Statutes (1991). It was the second area to be designated and now is one of only four areas in the State retaining this designation. The Green Swamp was designated because the area's natural resources were considered to be of regional and statewide importance and because of concerns that uncoordinated development could endanger these resources. The Green Swamp is a regionally significant area for recharge of the Floridan Aquifer. The Green Swamp is unique because the top of the Floridan Aquifer is at or near the surface over much of the area. This creates what is known as the potentiometric high of the Floridan Aquifer. The potentiometric high pressurizes the Floridan Aquifer, permitting it to be used for drinking water wells. The Florida Aquifer serves as the principal source of drinking water for central Florida. It supplies the entire State with about 48 percent of its ground water supply. The potentiometric high also serves to hold back salt water intrusion into the Floridan. Recharge is important in maintaining the potentiometric high of the Floridan Aquifer. Although the Green Swamp has been characterized as a recharge area for the Floridan Aquifer, the actual recharge capabilities of the Green Swamp vary considerably throughout the region. Some areas within the Green Swamp, such as the high, dry, sandy ridge on the eastern boundary of the Green Swamp clearly are high recharge areas. In some areas, the Floridan Aquifer rises essentially to the ground surface, with no confining layer above it. In those areas, a considerable amount of surface water filters into the Floridan Aquifer. In other areas, including in the vicinity of the project site, recharge capability is considerably less. See "G. Review under the 1985 Plan and the Flood Protection and Surface Water Management Code, (3) Ground Water Recharge." The head waters of several rivers, including the Withlacoochee River, are in the Green Swamp. Polk County's Comprehensive Plan. Polk County's Comprehensive Plan, as amended by Polk County Ordinance 85-08 (Ordinance 85-08), is referred to as Polk County's 1985 comprehensive plan, or the 1985 plan. It includes a Land Use Element (LUE) and a Conservation Element. The Land Use Element. The 1985 Plan is a "policy plan." As a "policy plan," the LUE does not map land use classifications or densities or intensities of development. The different parts of the plan must be considered together to ascertain their meaning. As stated in the Foreward to the LUE: The Policy Plan is a flexible and realistic guide to future public decisions. Existing conditions are first determined and analyzed. Then, community goals are identified providing a process of finding out where we are and where we want to go. * * * . . .. The challenge is to determine the means of achieving the identified community goals at minimal cost and the least possible hardship on any segment of our society. Under the policies planning process this is accomplished by developing all possible alternative courses of action that will advance the community toward the desire goal. The policies are then a general statement of purpose and outlining broad principles toward which the plan is guided in the implementation stage. A policy plan does not detail specific actions or locations on a map. Rather it provides a broad framework within which day-to-day decisions are made in a consistent manner toward an identified goal. The ultimate product of those community goals will be the heritage of Polk County's future. At 4-2, the LUE discusses the need to give attention to "the proper distribution of population densities in keeping with sound planning practices, the physical capabilities of the land, and the relationship of the population and housing densities to existing or proposed transportation facilities and other community services." It then speaks to "Retention of Open Spaces": A second potential problem to be faced, as urban growth continues, is the potential loss of the open space characteristics that now contribute substantially to its desirability as a community in which to live and visit. To a large extent, the desirable characteristics are provided by extensive agricultural areas. Such uses are compatible with residential and other types of urban land uses and should be encouraged to remain to the maximum extent possible. Desirable open space is also presently provided by . . . wetland areas not suited for urban development. By encouraging such areas to remain in their present condition, a substantial amount of open space can be retained to provide the needed visual relief and openness necessary within a highly urbanized community. At 4-5, discussing "Retention of Unique Agricultural Lands," the LUE states that cattle raising and field crops are subject to potential intrusion by urban development and states: "The development of planning techniques, which will encourage the retention of important agricultural lands and provide for orderly urban development, thus becomes a matter of considerable importance." The Goals, Objectives, and Policies (GOPs) of the LUE starting at 5-1 include the following: General Goal: To maintain productive and mutually compatible use of lands and waters within Polk County in a manner consistent with the economic, physical and social needs, capabilities, and desires of Polk County and its citizens. Objective I - Agricultural Uses: To ensure that a sufficient quantity of appropriate lands are available and protected for productive agricultural uses necessary to a sound economic base. Policies: * * * 2. Protect, to the maximum extent possible, agricultural lands from encroachment of incompatible land uses and any detrimental effects of development adjacent to agricultural areas. * * * 5. Provide all possible incentives for the retention of lands into agricultural production. * * * Objective III - Natural Resources Minimize adverse impacts of development on valuable natural resources including the protection of water quality and quantity in surface and ground waters. Policies: * * * 2. The subdivision and platting of land shall be permitted in accordance with the zoning district applied to the property and in compliance with the Polk County Subdivision Regulations and Flood Protection/Surface Water Management Ordinance. * * * Site alteration should be permitted only when such alteration will not adversely affect the natural flow regime or the natural recharge capabilities of the site. Site alteration should be permitted only when such alteration will not result in the siltation of wetlands or reduce the natural retention and filtering capabilities of wetlands. Site alteration activities should provide for water retention and settling facilities; should maintain an overall site runoff equivalent to the natural flow regime prior to alteration and should maintain a runoff rate which does not cause erosion. * * * Storm water runoff should be released into the wetlands in a manner approximating the natural flow regime. Structures should be placed in a manner which will not adversely affect the natural flow regime and which well not reduce the recharge capabilities. Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973. Groundwater withdrawal should not exceed the safe yield per acre as determined by Water Management Districts or successor agencies. Objective IV - Residential Areas To ensure that an adequate supply of appropriately located lands are available for the development and maintenance of residential areas that can be efficiently and effectively provided with necessary public facilities and services. Policies: Promote and encourage the provision of a wide range of housing opportunities, in appropriate locations, to permit a choice of housing types to suit the particular needs of all citizens. Promote and encourage new residential development adjacent to established growth centers, to ensure the orderly use of land and the efficient provision of facilities and services. * * * Encourage new residential development that can be effectively served by the existing transportation facilities. Promote new residential development in non-urban areas, that is properly designed to combine with future adjacent development, to create a neighborhood of sufficient size to facilitate the efficient and effective provision of all necessary public facilities and services. Part VI of the LUE, entitled "Alternate Approaches," discusses the pros and cons of different concepts for planning and managing of growth. It settles on a "Resource-Responsive Concept" as the preferred growth alternative. This concept holds in part: Wherever possible, future growth should be encouraged to take place in or near established urbanized areas. Scattered growth incapable of functioning as meaningful self-contained communities should be discouraged. And it is preferable that the urbanizing area, as it extends over extensive areas within the County, not be developed in one continuous, monotonous maze of residential, commercial, and industrial uses - but that there be open space provided at appropriate intervals so as to provide visual relief and a sense of scale to the overall urban community. Such open space areas can be productively utilized for agricultural and conservation purposes or recreation areas, public facilities and services required. It is proposed that the most appropriate urban growth concept to meet such guide-lines and the policy statements of this land use plan be a resource-responsive growth concept. Under this concept, urban growth and development will be guided and encouraged with respect to its responsiveness to the natural and human resource capabilities of the County. Within any given area of the County, the resources will be careful evaluated in terms of their capability to support growth, and the physical form and intensity of development will be then shaped to provide the physical form and intensity of development will be then shaped to provide a balance with such resources. Prime resources to be considered are as follows: Natural Resources Topography and soil conditions Vegetation and tree cover Wildlife habitats present Drainage characteristics; relationship to rivers and lakes Natural water supply capabilities General aesthetic qualities Human Resources Transportation facilities (roads, railroads, airports) Available water supply and sewage facilities Community facilities, such as schools, parks, libraries Protective services, such as fire and police Established land uses within the area Economic conditions and potentials. Part VII of the LUE, entitled "Implementation," states: "Initial implementation of a Comprehensive Plan and initiation of the continuing planning process for growth management requires the establishment of principals and standards for measurement of proposed activities against the adopted policies of the community." It includes a section entitled "Principles and Standards for the Control and Distribution of Population Densities and Structural/Development Intensity," which provides in part: All Types of Urban Development: * * * Each new development or land use should follow sound land planning principles to maximize site advantages, avoiding when possible, adverse impacts on the natural resources and hazards to health, safety, or general welfare. * * * Residential Development: Low-density single-family development (1-4 units/acre), other than rural residences related to agricultural operations, shall be located in areas capable of being developed into stable, cohesive neighborhoods. In a section entitled "Legal Requirements of Implementation," it states that "all actions taken by local government, whether in the form of permitting private development to occur or in the provision of public facilities and services, are required to be fully consistent with the adopted Comprehensive Plan. The plan, once adopted, must occupy a central position in the consideration of all proposed development." In another section, entitled "Coordination with Other Plan Elements," it states that the "land use element cannot be implemented alone [but] must be coordinated with the [other elements]." In another section, entitled "Needed Improvements in the Zoning Ordinance," it is recognized that "it will be essential that a thorough review of the zoning ordinance be undertaken and that the ordinance be revised as appropriate to achieve consistency with overall planning objectives." It acknowledges that there were "major identified deficiencies in the current zoning regulations" and advises that "the following needs among others should be addressed as a minimum in making revisions to the zoning ordinance": "Revision of the Density Requirement in Residential Districts." Despite the admonitions in the 1985 Plan, to date there has been no revision of the land use classifications, densities, or intensities in the County's zoning code. As before the 1985 Plan was adopted, zoning in the Green Swamp ACSC remains Rural Conservation (RC) and allows up to one unit per acre residential development. The Conservation Element. Part II of the Conservation Element of the Polk County Comprehensive Plan is a "Summary of Natural Resources." At 2-18, there appears a section entitled "Rare and Unique Natural Resources," which describes the Green Swamp, as well as other natural resources in the County, as a "rare and unique land area resource for conservation consideration." At 2-19, as amended by Ordinance 85-08, this element of the comprehensive plan also states: This area comprises the hydrologic heartland of Central Florida and contains the headwaters of the Withlacoochee, Hillsborough, Peace and Oklawaha Rivers. The potentiometric high of the Floridan Aquifer lies within this area. . . . The area has a high potential for recreational and natural enjoyment. . . . The Green Swamp area is the largest expanse of forest in Polk County, with abundant water and wooded areas to provide for wildlife habitats. This area has great significance as an area for conservation of land, air, water, open space and wildlife habitats. Part IV of the Conservation Element is a "Summary of Special Problems, Areas, Issues, and Relationships." Starting at 4-2, it addresses the following: Displacement . . .. Cities in Polk County have historically developed on the ridges and the urbanized areas are spreading outward rapidly into the prime citrus lands and the "marginal" (flood prone) lands. There is considerable concern about urban development in wetland soils and flood prone areas. The double barreled concern for development in wetland soils and wetland areas is that they might well serve valuable natural functions and the private and public problems created by development subjected to flood damages. This property damage promotes public pressure for drainage in wet areas. The issue in wetland drainage and flood control is the jeopardy of natural functions that wetlands and water fluctuations provide in natural systems and flood damage costs. . . . [C]oncern for the growing demand for uplands development which steadily displaces [good pasture land] . . . relate[s] to the use of good pasture land for development. Density The subject of development density is a particular issue of vital importance to the county. Low density development in some areas and high density in other areas is important so that demands for public facilities can be economically and efficiently handled, so that environmental degradation is minimized, and so that land, not suitable for development, can be saved for important natural functions. The present zoning ordinance classifies most of the county in a Rural Conservation (RC) classification that permits low density development without proper regard for those areas that are best suited for development. Portions of the county should be protected from development pressures and appropriate areas should be zoned to accommodate rational densities. The present level of protection, provided by the zoning system is not brought to bear for conservation purposes. * * * Water * * * Another area of concern relates to the draw down and recha[r]ge of the Floridan Aquifer and is claimed to be a rational concern of an area much larger than Polk County. * * * Pollution Environmental pollution, as it relates to water, is a major local concern. * * * Water pollution is concerned because of its effects on recreation and tourism. Water degradation and the pollution of lakes and rivers tends to remove the intangible value that Polk County enjoys in thee form of its surface water resources. * * * Also, the related cost issues of municipal sewage treatment and disposal, effluent disposal techniques, septic tank useage are environmentally economic choices to be made by the public. Discussing the topic, "Preservation and Management," starting at 4-4, Part IV of the Conservation Element states in part: Many issues relate to what, how, or when something should be conserved. * * * Lakes, rivers and canals of the county are of concern as sources of flooding and as resources for flood control, if properly managed. Flood prone areas surrounding surface water have been identified for much of the county. These water bodies are also legitimate concerns as the habitat for fish and other wildlife that provide a significant value in their own right. The area of these water bodies are also special scenic and recreational values that contribute to tourism and development. Part V of the Conservation Element is where the "Goals, Objectives and Policies" are found. It start with some general observations, including in part: . . .. It can be expected, therefore, that the natural environment of the county will continue to undergo modification of one type or another in response to the needs of people. . . . The inventory of total space will, therefore, diminish as these changes take place, resulting in corresponding losses within particular categories of natural resources. What is important is that no critical loss of impairment of a natural resource take place; that development be managed so as to create minimum disturbance of the remaining natural resource systems; and that there be compensation replenishments of resources wherever possible. It then lists a General Goal and several resource-specific objectives and policies: General Goal: Maintain, protect, develop and utilized the natural resources in a manner that will balance and replenish the natural ecological systems and will best serve and promote the desired quality of life for Polk County resident, present and future. * * * Water Resource Objective: To conserve and protect the quality and quantity of water resources through proper management. * * * 6. Identify and protect significant acquifer [sic] recharge areas for maximum recharge capability and protect the water available for aquifer recharge. * * * Minimize the adverse impacts of development on resources of the Floridan Aquifer, wetlands and flood-detention areas. Protect the normal quantity, quality and flow of ground water and surface water which are necessary for the protection of resources of state and regional concern. Protect the functions of the Potentiometric High of the Floridan Aquifer. Prevent further salt-water intrusion into the Floridan Aquifer. Protect or improve existing ground and surface-water quality. Protect the water retention and biological-filtering capabilities of wetlands. Protect the natural flow regime of drainage basins. Rare and Unique Natural Resource Objective: To conserve and protect, through proper resources management, areas having unique natural characteristics and particularly sensitive environmental balance. * * * Policies: Identify all significant areas in Polk County deemed to have unique natural resource characteristics. Encourage proper management of unique wetland areas of the County as a vital water resource. Encourage a proper system for control of development in flood prone and wetland areas to regulate alternation [sic] of the natural system of water retention and storage during periods of heavy rainfall. Preserve and protect, to the maximum extent possible, all delineated areas having valuable unique resource characteristics. Part V of the Conservation Element concludes with a "Summary," which states in part: The objectives and policies set forth above should not be considered as controls to be rigidly applied in every instance of decision-making dealing with the natural environment. Rather, in dealing with resource conservation issues, guidance is preferable to control. . . . A number of potential implementation actions and programs, presented in the following part, will further assist in establishing the direction and scope of conservation activities in the County. Part VI of the Conservation Element is entitled "Implementation." While acknowledging at 6-1 that Polk County cannot establish an implementation program unilaterally, without regard to the co-responsibilities of other governmental authorities at the regional state and federal levels, it states at 6-2 that Polk County "can and should": Utilize the general objectives and policies established by this Element as considerations in all decision making concerning the use and improvement of land within the County. * * * 3. Utilize, to the fullest extent possible, the policies and implementation controls of other elements of the Polk County Comprehensive Plan, and those of other governmental entities having jurisdiction, to further the conservation of natural resources. Starting at 6-3, Part VI discusses the Conservation Element's "Relationship to Other Plans." At 6-4, after stating that the Conservation Element will be largely implemented through the policies and programs of other comprehensive plan elements, Part VI provides: Land Use Element - This element will provide the overall framework for conservation [sic] potentialities through the manner in which land uses are distributed, arranged, and interrelated throughout Polk County. Policies and implementation programs of this element will determine the degree to which new development is properly related to soil types and capabilities, natural habitats, flood prone areas, wetlands and unique resource areas of the County. Land regulatory controls such as zoning, subdivision regulations and development impact reviews provide the basic tools for implementation of the policies of the Land Use Element. Starting at 6-5, Part VI discusses "Guidelines for Implementation." At 6-5, it points out: The nature of conservation policy, being of such broad application and diversity of interest, requires that its effective implementation utilize many approaches, techniques and procedures. Its application is carried out, for the most part, in an indirect way as a by-product of other more direct decisions and actions relation to the development and growth of the County. It is essential, therefore, that Polk County draw upon all possible alternative mechanisms and techniques which will lead to the effective conservation of its natural resource systems. Among the various approaches which Polk County may utilize to further its conservation objectives are the following. * * * Influence in the allocation of resources to achieve the objectives of the conservation plan. Control of events which determine resources allocation in keeping with the conservation plan. * * * Specific procedures and techniques which may be utilized to facilitate the implementation process include the following. * * * 7. Protect natural water bodies and adjacent wetland areas through the regulation of development densities and proper management of stormwater runoff. This would require a cooperative effort with the Water Management Districts in identifying flood plains for various flood frequencies. Polk County's Flood Protection and Surface Water Management Code. Polk County's Flood Protection and Surface Water Management Code was enacted as Ordinance 81-28 and was amended by Ordinance 85-07. Article V is entitled "Flood Protection Standards." Section 5-1 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to new construction and substantial improvements in all areas of special flood hazard, and to any development, other than phosphate mining, within 100 feet of a watercourse: * * * (6) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. Section 5-2 provides in pertinent part: SPECIFIC STANDARDS: The following minimum standards shall apply in all areas of special flood hazard where base flood elevation data has been provided: * * * Subdivision Proposals: All subdivision proposals and other proposed developments shall be reviewed by the County Engineer. [I]f the proposal is in an area of special flood hazard, it shall be reviewed to assure that the following standards are met: All such proposals shall be reasonably safe from flood waters resulting from the base flood. All such proposals shall have public utilities and facilities such as sewer, gas electrical and water systems located and constructed to minimize flood damage. Base flood elevation data shall be provided for all such proposals. Roads shall be reasonably safe from flood waters resulting from the base flood. Article VI of Polk County's Flood Protection and Surface Water Management Code is entitled "Water Management Standards." Section 6-2 provides in pertinent part: GENERAL STANDARDS: The following minimum standards shall apply to all development which occurs within an area of special flood hazard and to any man-made change to improved or unimproved real estate . . .. * * * (3) (a) The amount of site alteration within a wetlands soil association shall be limited to ten percent (10%) of the area of wetlands soil association within any given total site. Review under the 1985 Plan and the Flood Protection and Surface Water Management Code. Land Use, Density and Intensity. DCA alleges that the land use, density and intensity of the development Crowder proposes for the site is inconsistent with: (1) the section on "Density" found in Part IV of the Conservation Element, entitled "Summary of Special Problems, Areas, Issues, and Relationships"; (2) a section of Part II of the Conservation Element of the Polk County Comprehensive Plan entitled "Rare and Unique Natural Resources"; (3) Policy 2, Objective I, "Agricultural Uses," in Part V of the LUE; and (4) Policy 2, Objective IV, "Residential Uses," in Part V of the LUE. 6/ As previously stated, the 1985 Plan is a policy plan that does not map land use classifications or densities or intensities of development. Crowder's Paradise Country Estates is consistent with the County's Zoning Code, which has not changed since before the 1985 plan, and Zoning Map. The development was not otherwise reviewed for land use, density or intensity. But it is clear that the 1985 plan does not condone exclusive resort to the zoning code to determine the appropriateness of the land use, density and intensity for development in the Green Swamp ACSC. See, especially, the section entitled "Density" in Part IV of the Conservation Element of the Plan. In the Green Swamp ACSC, especially, reference must also be made to the Plan itself. See Part VII of the LUE, entitled "Implementation." It is not found that all residential use on the Crowder property would be, in itself, inconsistent with the 1985 Plan. But, taking into consideration all of its land use, density and intensity provisions, it must be found that the development order issued in this case, especially at its level of density and intensity and especially in the manner of its issuance, is inconsistent with the 1985 Plan. The crux of the problem with this development, like others in the Green Swamp ACSC already permitted by County development orders, is that, first, the 1985 comprehensive plan and the County zoning regulations in place at the time were inadequate and, second, the steps envisioned in the plan to make them adequate have not been taken. For the plan and the zoning regulations to be adequate, and for a development order for a project in the Green Swamp ACSC in Polk County to be consistent with the 1985 comprehensive plan, either: (1) the plan must be amended to map land use classifications, densities and intensities of development in the Green Swamp ACSC; (2) the zoning code must be amended as envisioned in the comprehensive plan for the Green Swamp ACSC; or (3) the County must evaluate development orders for projects in the Green Swamp ACSC on a case- by-case basis for consistency with the comprehensive plan. None of these three possibilities happened in this case. 7/ Flood Plain Delineation. Paragraph 12 of the DCA Petition alleges that the Crowder development violates Policy 10 of Objective III, "Natural Resources," of the LUE: "Placement of structures shall be consistent with sound flood plain management practices such as compliance with the Flood Disaster Protection Act of 1973." Specifically, it is alleged that the use of a Federal Emergency Management Agency (FEMA) undetailed "A" zone to map the flood prone area on the site, and the failure to perform a detailed study, did not comply with the Flood Disaster Protection Act of 1973. Other allegations in the DCA Petition also implicate the delineation of the flood prone areas on the site. See, (5) Ground and Surface Water Quality, below. A FEMA "A" zone is the zone depicting the area determined by FEMA to be flood prone. In this context, FEMA defines a "flood prone" area as an area flooded in a 100-year, 24-hour storm. At the time Polk County reviewed the Crowder project for approval of the roadway and construction drainage plans, FEMA was requiring that a detailed study be performed to delineate the flood prone area. Polk County apparently was not aware of this requirement and was not enforcing it. Nor, apparently, was Crowder's engineer aware of it. In any event, Crowder did not have a detailed study performed to delineate the flood prone area on the site, and the County did not require it. In approximately March, 1992, Polk County received a written communication from FEMA advising of the requirement for a detailed study of the flood prone area in the case of developments like Crowder's. Polk County now requires compliance with this FEMA requirement. Crowder did not rely simply on the FEMA undetailed "A" zone to map the flood prone area on the site. Crowder's engineers used the existing undetailed FEMA maps as a starting point for determining base flood elevations. The engineers digitized the areas which had been designated as flood prone on the FEMA panels. The engineer then overlayed the digitized FEMA map with the on- site wetlands survey of the property, which had been field-staked and field- shot. Topographical field shots of the property which had been conducted throughout the site at one foot intervals were also overlayed on the digitized FEMA map. In addition, the engineer took into consideration mapped wetlands soils and compared flooding conditions which had occurred on adjacent property to assess whether all areas actually prone to flooding had been characterized as flood prone on the FEMA map. The methodology used by the project engineers was based on sound engineering practices. Nonetheless, it does not qualify as a "detailed study" as far as FEMA is concerned. A "detailed study" would include the application of a computer program that would "route" hypothetical flood waters onto and through the property to ascertain flood elevations in different stages of the hypothetical flood. It is not possible to determine how a detailed study would change the delineation of the flood prone area in Crowder's proposal. The total area of flood prone area could either increase or decrease; it could increase in some places and decrease in others. As it is, several of the lots platted in the Crowder development would be entirely within both the FEMA undetailed "A" zone and the flood prone area mapped by Crowder's engineers. Ground Water Recharge. DCA alleges that platting Paradise Country Estates will adversely impact recharge of the Floridan Aquifer, contrary to Policy 9 and 11, Objective III, "Natural Resources," of the LUE, and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. In the vicinity of the project site, the Floridan Aquifer comes to within 35 feet approximately of the ground surface. Above the Floridan Aquifer is a shallow aquifer, which rises to within approximately 12 inches of the surface. There is a layer of clastic soils (sand and clay) between the surficial aquifer and the Floridan Aquifer. This confining layer slows the rate of recharge to the Floridan. As a result, the project site is in an area having low, or even very low, to moderate recharge capabilities, at best. USGS Professional Paper 1403-E, which was released in 1990, uses groundwater modelling to quantify recharge rates, instead of using qualitative terms such as "low," or "poor," "moderate" and "high" to describe recharge capabilities. USGS Professional paper 1403-E reports that many areas in the Green Swamp previously labeled as good, moderate or high recharge areas are actually capable of only recharging at rates of 3 to 4 inches per year. The subject property appears to be in the 2 to 3 inch range per year for recharge according to USGS Professional Paper 1403-E. Only three known sample soil borings have been taken on the project site. As a result, the extent of permeability and overall thickness of the confining layer between the surficial and Floridan aquifers is not certain. But there is no reason to believe that there are any karst features or other geologic faults in the area that would allow for direct connections between the surficial and Floridan aquifers. The soil borings that have been taken on the site verify the various geological surveys and studies describing the recharge capabilities in the area. Due to the site's limited capabilities as a recharge area, it is unlikely that the platting of this site will result in any significant reduction in its natural recharge rate. The project is not inconsistent with Policy 9 or 11, Objective III, "Natural Resources," of the LUE, or Policies 9 or 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. Individual Water Well Use. DCA alleges that the planned use of individual water wells in Crowder's Paradise Country Estates will impact the quantity of the Floridan Aquifer (and the surficial aquifer) contrary to Policy 11, Objective III, "Natural Resources," of the LUE, and Policies 9 and 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. The potentiometric level of the Floridan Aquifer protects the Floridan Aquifer from salt-water intrusion. Significant de-watering of the aquifer caused by large municipal or industrial wells extracting a high volume of water from the aquifer at an intense rate can lower the potentiometric pressure, thus increasing the potential for salt-water intrusion into the aquifer. (Furthermore, the lowered potentiometric pressure creates a hydraulic gradient which encourages surface waters to percolate downward at a faster rate due to the decreased pressure in the Floridan Aquifer. See the preceding sections on Ground Water Recharge and the following section on Ground and Surface Water Quality.) Large municipal, industrial or agricultural wells which exceed 6 inches in diameter must obtain consumptive use permits from the SWFWMD. The Water Management District takes into account what the District determines to be a safe yield per acre when issuing a consumptive use permit. Small, residential wells are not subject to this permitting process as their impacts are much smaller and less intense, and not a concern with regard to their effect on the potentiometric pressure. For this reason, some coastal areas have begun using smaller, individual wells as an alternative to larger municipal wells. The Floridan Aquifer is replenishing itself fast enough for residential wells not to "de-water" or "draw down" the aquifer's supply of ground water. Residential wells do not lower the potentiometric pressure of the Floridan to a significant degree. Nor would they affect the normal supply of ground water, or contribute to salt-water intrusion. Pumping tests performed within two to three miles west of the project site which utilized several residential-size wells support the foregoing conclusions. For these reasons, it is found that the development will not adversely impact the normal supply of ground water and thus will not interfere with the functions of the potentiometric high of the Floridan Aquifer, including its protection against salt-water intrusion. Since the water wells would pump only from the Floridan Aquifer, they would not impact the supply of surface water. In regard to the use of water wells, the project is not inconsistent with Policy 11, Objective III, "Natural Resources," of the LUE, or with Policies 9 or 10 of the "Water Resource Objective" of the Conservation Element, of the 1985 comprehensive plan. Ground and Surface Water Quality. DCA alleges that Paradise Country Estates will result in unacceptable contamination of the Floridan Aquifer, the surficial aquifer, and the surface water (particularly the Withlacoochee River) contrary to Policies 9, 10 and 14 of the "Water Resource Objective" of the Conservation Element. Paragraph 20 of the DCA Petition alleges that the use of individual on-site disposal systems (OSDS), or septic tank systems, in violation of Section 5-1(6) of Polk County Ordinance 81-28 (the County Flood Protection and Surface Water Management Code), 8/ in particular, will be part of the cause of the unacceptable contamination (other causes being from lawn and garden maintenance and automotive wastes.) On-Site Disposal Systems. Chapter 10D-6, Florida Administrative Code, sets forth requirements for the use of on-site waste disposal, or septic tank, systems in the State of Florida. That chapter, which is administered by the Department of Health and Rehabilitative Services ("HRS") through local health departments, provides construction standards for the installation of on-site waste disposal systems. The septic tank serves as a holding tank designed to separate solids and floatable materials and allows anaerobic digestion of organic materials. The remaining effluent exits the tank into the soil infiltrative process, which is referred to as the drainfield. The drainfield is composed of gravel placed around perforated pipes, which are designed to evenly distribute and release the effluent into soil material where the effluent undergoes aerobic digestion. Eventually, any constituents remaining in the effluent which have not been absorbed by the root zone or otherwise decomposed reach the subsurface waters which are referred to as the surficial water table. Each individual lot owner will be required to obtain a permit from the local health department prior to installing an on-site waste disposal system. Prior to issuing a permit, HRS inspects each site to assess soil limitations and to conduct a percolation test to determine the seasonal high water table for the site. Because the soils on the site are severely limited for filtration purposes and the high water table is only 10 to 12 inches below the surface, individual lot owners will be required to mound their on-site waste disposal systems to overcome these limitations. Although the fill used to mound the systems will be comprised of suitable soils, it is possible that the foreign soils will absorb moisture from the existing soils on this site, a phenomenon referred to as capillary fringe affect. This phenomenon can cause those portions of the fill which come in direct contact with the existing soils on the site to lose their filtration capabilities. Unless the fill becomes saturated from other sources, it is unlikely that capillary fringe affect will render the filtration process ineffective. The effects of capillary fringe affect can be lessened by mixing fill with soils found on the site, a practice undertaken by contractors when installing on-site waste disposal systems. In addition, increasing the amount of fill used to mound the system would decrease the potential affects of this phenomenon. 9/ Floridan Aquifer Water Quality. In some areas of the Green Swamp, the Floridan Aquifer is actually considered a surficial aquifer since no confining layers of soil or clay separate the subsurface water from the Floridan Aquifer. These areas would typically be characterized as areas with high recharge capabilities (or high potential for contamination). However, throughout the project site, a confining layer exists which is composed of clayey sands which have a very low permeability. Therefore, there is relatively little interaction between the surficial aquifer and the Floridan Aquifer on this particular site. For this reason, the use of individual on-site waste disposal systems on this site would pose no significant risk to the water quality of the Floridan Aquifer. Surficial Aquifer and Surface Water Quality.-- As for the surficial aquifer and surface water quality, Chapter 10D-6, Florida Administrative Code, requires on-site waste disposal systems be located at least 75 feet from waterbodies. Normally, and when the systems are operating properly, this assures that adequate filtration and decomposition occurs before wastewater reaches surface waters on or near the site. But, in the case of the Crowder proposal, it is necessary to consider that at least some of the mounded systems will be subjected to flooding and will become saturated. Even based on the analysis by Crowder's engineers, 51 of the lots in Paradise Country Estates are entirely flood prone; there is no place to put an OSDS on those lots that is not flood prone. If a "detailed study" had been done, it is possible that more lots would be entirely within the flood hazard zone. Other lots not entirely within the flood zone may not be able to accommodate an OSDS on the part of the lot not within the flood zone. If the OSDS mound is saturated during flood conditions, the system will fail, and untreated waste, or inadequately treated waste, will be released into the surface flood waters. This waste water will move laterally across the project site. Roots may absorb some nitrates or other organic compounds; 10/ otherwise, the waste water and its constituents will remain in the surface water. Lateral movement across the site generally will be slow, as the site is relatively flat. Some of the waste water and its constituents will get into the surficial aquifer. There are ditches or canals alongside and on the site that will direct the rest of the surface water into Pony Creek and other tributories of the Withlacoochee River, an Outstanding Florida Water approximately three and a half miles to the north. The Department of Environmental Regulation issued a dredge and fill permit for the project's road network's impact on wetlands on the site. But it did not pass on the use of OSDS in the individual lots. It also erroneously referred to the Withlacoochee as a natural Class III, instead of an Outstanding Florida Water. See F.A.C. Rule 17-302.700(9)(i). The Southwest Florida Water Management District (SWFWMD) issued a surface water management permit for the project. In evaluating a permit application, SWFWMD considers surface water quality. But the focus of SWFWMD's inquiry is the pre- and post-development peak flows. Also, when it considers water quality, SWFWMD considers the impact of site alteration on water quality, not the impact of the use of OSDS on the site. In addition, the Crowder project was reviewed under special criteria for low-density rural subdivisions that do not require the submission of as much information. It was not clear from the evidence precisely how SWFMD evaluates water quality under those criteria. For these reasons, based on the evidence, it cannot be said that the Crowder project's OSDS will be meet the minimum standard of being "located to avoid impairment to them or contamination from them during flooding," as required by Section 5-1(6) of Polk County Flood Protection and Surface Water Management Code, or that the project will "protect the normal . . . quality of ground and surface water . . . necessary for the protection of resources of state and regional concern," as required by Policy 10 of the "Water Resource Objective" of the Conservation Element of the Plan. Finally, the project will not "protect or improve existing ground and surface-water quality," as required by Policy 14 of the "Water Resource Objective" of the Conservation Element of the Plan. Other Appeal Issues. Except as set forth above, the Crowder development did not violate the 1985 comprehensive plan and Flood Protection and Surface Water Management Code provisions cited in the DCA Petition. Agency Practice - Other Development in the Area. As previously described, Evans Acres, to the west of the Crowder site, was approved by DCA in 1983. (See Finding 10, above.) As approved, it was comprised of 48 lots on approximately 1,290 acres (a density of one unit per 27 acres). The original lots ranged in size from 5 to 60 acres. Unbeknownst to the DCA, individuals apparently have since split their lots and many of the existing lots are 2 to 5 acres in size. A proposed development known as Turkey Creek is located between the project site and Evans Acres. Turkey Creek is comprised of approximately 57 lots on 170 acres with a gross density of 1 unit per 3 acres. The physical characteristics of the Turkey Creek property, including the abundance of wetlands and floodplains, are essentially the same as the proposed project site. DCA appealed Turkey Creek in June of 1992. However, in that case, the County had been approximately two years late in rendering the Turkey Creek development order to the DCA. Meanwhile, the developer incurred development expenses and already had constructed roads and drainage facilities for the development. The developer, the County and DCA executed a settlement agreement which allows the development to proceed according to the original construction plans, but requires homeowners to install dual septic tank systems and have their septic tanks cleaned and inspected every three years. Several other developments, which are in the general vicinity of the project site and have many of the same physical characteristics, including Yearling Trace and Buck Hill, have been appealed by DCA. Yearling Trace is comprised of 108 units on approximately 544 acres. Buck Hill is comprised of 55 units on approximately 214 acres. Those projects were appealed by DCA in June and April, 1992. In some of these cases, the County did not timely render development orders to DCA in a timely manner. In the case of Buck Hill, the DCA had been mailed an unapproved copy of development plans in October, 1990; in early 1992, DCA contacted the County to inquire, as no County-approved development plans ever had been sent to the DCA. In many of these cases, substantial development expenses had been incurred; in some cases, roads and drainage facilities already had been constructed. DCA decided to settle the pending appeals in which the County was late rendering the development order, and in which the developer already had constructed roads and drainage facilities, consistent with the Turkey Creek settlement. In cases where the County was late rendering the development order, but the developer had not already constructed roads and drainage facilities, the DCA determined to settle not only for stipulations to upgrade the OSDS, as in the Turkey Creek settlement, but also for requirements that a "detailed" flood zone study be done, in accordance with the FEMA requirements. Prior to the DCA appeal, Crowder had expended approximately $31,000 in permit fees. In addition, he has incurred development costs, primarily for engineering fees and related services. Through the time of the final hearing, he had spent approximately $99,000 on engineering fees and services. (The evidence was not clear how much had been incurred by the time of the DCA appeal.) However, the County was not late in rendering the Crowder development order, and Crowder has not constructed roads or drainage facilities. In view of the different circumstances in Crowder's case, DCA's prior agency practices do not compel that Crowder's development be treated in the same manner, i.e., be settled on the same terms, as the Turkey Creek and the others. DCA has argued that FLWAC's Final Order in the case of Dept. of Community Affairs v. Narbi International Company, Inc. and Lake County, 14 FALR 3223 (1992), controls this case and requires the Crowder development order to be overturned on appeal. Narbi involved development Green Swamp ACSC, albeit in Lake County. Factually, there are many differences between Narbi and this case. The Narbi development order was a rezoning from agricultural with a residential density of up to one unit per five acres to a residential planned unit development (PUD) zoning with a density of one unit per 1.35 acres. Also, Lake County's comprehensive plan had an "urban containment policy," which DCA equated with its non-rule policy preventing "urban sprawl" or "leap-frog development." Thirdly, in Narbi, it was found that a geologic fault existed on the project site which allowed a direct connection from the surficial aquifer to the Floridan Aquifer. Because of the factual differences, Narbi does not control the outcome of Crowder's case. Conditions for Approval. Based on the testimony of its witnesses, DCA has proposed that, notwithstanding its deficiencies, the Crowder project can be approved if its density is lowered to between one unit per ten acres and one unit per 20 acres. The rationale of DCA's witnesses seems to be that the proposed lower density, in and of itself, would cure at least the most significant of the deficiencies. Since the Crowder development order under review was for approval of particular road and drainage plans, the plans would have to be redrawn at the lower density and resubmitted for approval by the County subject to the final order to be entered in this case. It is not possible for the Commission to approve, on condition of lowered density, the plans that were the subject of the development order in this case.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Florida Land and Water Adjudicatory Commission enter a final order rescinding and denying approval for the development order in this case. RECOMMENDED this 10th day of March, 1993, in Tallahassee, Florida. J. LAWRENCE JOHNSTON Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 10th day of March, 1993.
The Issue Whether application 23181 for a consumptive use water permit should be granted, pursuant to Chapter 383, Florida Statutes. Prior to the hearing, 16 individuals in the Wabasso, Florida, community petitioned to intervene as parties in this proceeding. By Order, dated August 26, 1976, intervention was granted. Thereafter, counsel for the Wabasso Citizens Association, a private, unincorporated association that included the 16 prior intervenors, requested that intervention include all members of the association. There being no objection to the foregoing request, intervention was granted accordingly. The public hearing in this matter included 22 exhibits and the testimony of 21 witnesses, nine of whom were members of the public. Lists of the exhibits and public witnesses are attached hereto. On January 8, 1975, the Town of Indian River Shores, Florida (hereinafter "Town"), and Lost Tree Village Corporation, Indian Rivers Shores, Florida (hereinafter "Lost Tree"), filed application 23181 for a consumptive use water permit with the Central and Southern Florida Flood Control District (hereinafter "District"). The application requested a permit for the withdrawal of 393 acre feet per year of groundwater from two wells located on a parcel of land owned by Lost Tree at Wabasso, Florida. The requested use was for irrigation of two golf courses located on land owned by Lost Tree known as John's Island, a residential community located within the Town, and as an emergency public water supply for the Town. It was proposed that the water be transported by pipeline owned by Lost Tree from Wabasso to John's Island, a distance of several miles. Although the matter was set for public hearing to be held on February 4, 1975, an unfavorable staff report of the District, dated January 30, 1975, resulted in an indefinite postponement of the hearing. A hydrogeological report was prepared for Lost Tree by a consulting firm on February 12, 1976, and submitted by the applicant to the District. A subsequent staff report of the District was prepared on July 28, 1976. Thereafter, the matter was noticed for hearing to be held August 31, 1976. Pursuant to the request of intervenors, a continuance was granted until September 29, 1976. (Exhibits 5,6,7,8,19)
Findings Of Fact The Town is a municipality that was incorporated in 1953. It is located east of the Indian River on an island and extends from the north boundary of Vero Beach for over 4 miles along the Atlantic ocean. In 1969, Lost Tree commenced developing a 3,000-acre tract of land located within the Town as a residential community. Prior to the initiation of this project, there had been very little development in the Town. In order to attract residents to John's Island, two 36-hole golf courses were constructed on the property, known as the North and South Courses, covering approximately 180 acres. At the present time, John's Island comprises over 600 residences, consisting of single and multiple family units, ranging in price from $65,000 to $500,000. The Town has a population of about 1,200, with 65 percent residing at John's Island. The present assessed value of property located in the Town is about $160,000,000 of which almost $66,000,000 is attributable to property in John's Island. The private golf club at John's Island has approximately 500 members, including about 150 from Vero Beach. The golf courses are considered to be the "heart" and "life-blood" of the community (Testimony of Ecclestone, Miller; Exhibits 5,11,12). The water supply of the Town comes from the water system of the City of Vero Beach, pursuant to contract, via a 16" water main which crosses the Indian River and ends at the northern boundary of Vero Beach. There, it is tied into a 12" water main of the Town. The Town has a one million gallon capacity underground storage tank and a 100,000 gallon overhead tank. The 16" main is the only waterline that crosses the Indian River and, in the event of a rupture, the Town would be limited to its stored supplies (Testimony of Miller, Little, Exhibits 5,17). The John's Island golf courses require irrigation of approximately 70 acres. In the past, irrigation water has been obtained from a system of shallow wells on the property, treated sewage effluent from the surrounding community, and stormwater, all of which is discharged into two ponds located on the courses. Additionally, treated potable water is obtained from the City of Vero Beach through two two-inch water meters that were installed in 1975. Prior to that time, an undisclosed amount of city water was obtained for irrigation and other purposes through city meters installed on fire hydrants in the area. The use of city water was required in order to supplement the resources available on the John's Island property. During the period May, 1975, through August, 1976, the amount of water obtained from the City of Vero Beach that was used for golf course irrigation totaled 54,057,000 gallons, an average of some 110,000 gallons per day. At the present time there is no water problem, insofar as irrigation is concerned, on the South Course which obtains irrigation water from sewage effluent and a number of shallow wells. However, test samplings over the years have shown a gradual increase in the amount of chlorides in the water and it is questionable whether such water will continue to be suitable for irrigation in the foreseeable future. Recent tests show the chloride content of the water at 450 ppm. The type of Bermuda grass on the golf courses can grow satisfactorily with water containing not more than 1,000 ppm. City water is used only on the North Course. The water obtained from the shallow wells in that area is highly saline in content. A recent water test showed a chloride content of 3,800 ppm. Additionally, immediately before an eight inch rainfall which lowered the chloride content to the foregoing figure, the greens on the North Course tested at 6,300 ppm in chloride content (Testimony of Luke, Little, Exhibits 6,7). During periods of drought, the City of Vero Beach has requested John's Island and other water users to either curtail or stop the use of city water for non-domestic purposes. Such requests have been received approximately six times during the past year. In April, 1976, the city water used for golf course irrigation at John's Island was shut off for a period of eight days as a result of a request from officials of Vero Beach. If insufficient irrigation water is not received for a period of 10 days to two weeks, it is extremely probable that a golf course would have to be replanted at an approximate cost of $60,000.00 to $80,000.00 and would require a period of six months for suitable growth. Both the Town and John's Island always cooperated fully with the requests of Vero Beach to curtail water use (Testimony of Luke, Miller, Little, Exhibit 17). At the time irrigation water sources were being explored at John's Island, a test well was drilled to a depth of 2020 feet into the Floridan aquifer underlying the property, but an inadequate quantity of water was developed. Lost Tree owns some 25 acres of land at Winter Beach, Florida, which is located west of John's Island across the Indian River. Although test wells there produced satisfactory water, it was not feasible to use this source due to prohibitions against excavation for such purposes in the Indian River. Due primarily to economic considerations of the high cost of using treated city water for golf course irrigation, and the inconvenience and possible hazards of water interruptions from that source, Lost Tree decided to supplement its resources from water withdrawn from wells to be located on a 4.869 acre tract of land it purchased in Wabasso. Although a deep well was considered at that site, state agencies advised that the Floridan aquifer was overloaded in that area to a degree of 200 percent. Accordingly, in 1973, two ninety-foot deep wells were constructed on the site approximately 500 feet apart into the underlying shallow aquifer. Pump tests showed that the chloride content was within satisfactory limits. Thereafter, Lost Tree in its own name and that of The Town, obtained necessary rights-of-way and permits for the placement of a system of pipes for transportation of water from the Wabasso wells to John's Island. These consisted of a 16" water line from the Wabasso site east over a newly constructed bridge and several existing bridges to Highway A1A where the size of the line south to John's Island was decreased to twelve inches. An agreement was entered into between Lost Tree and the Town on December 19, 1974 whereby the former agreed to supply emergency needs of the Town from water obtained from the Wabasso wells. About that same time, the pipe system was completed and the present application filed with the District (Testimony of Lloyd, Ecclestone, Exhibits 2,6,9). The area immediately surrounding Lost Tree's land in Wabasso consists primarily of residences, groves, and trailer parks. The residents of the unincorporated Wabasso area depend solely upon the shallow aquifer for their domestic water needs since there are no utility services in the area. Grove irrigation normally is accomplished by deep wells to the Floridan aquifer. After the application herein was filed in January, 1975, numerous letters of objection to the proposed withdrawal were filed with the District by residents of the Wabasso community and from local organizations. These objections, for the most part, expressed apprehension that the applicants would be withdrawing far more water from the well field than their fair share based on the size of Lost Tree's land in Wabasso. The objectors also claimed that the requested withdrawal would have a serious detrimental effect on existing users. They further protested the concept of extracting potable water from one area and transporting it to another area for irrigation use on recreational facilities. The initial Staff Report of the District on January 30, 1975, took such objections into consideration and recommended denial of the application based on the unsuitability of the well field site. It found that withdrawal of the requested water for golf course irrigation was not a reasonable and beneficial use because it greatly exceeded the water budget for the site, harmed existing legitimate users in the area by creating drawdowns of several feet which would increase the possibility of potable water supply wells running dry, harming potential future legitimate users by lowering the water table and exporting the water that they might have utilized, and because it threatened to harm such users and the resource itself by "upconing" saline water from the bottom of the aquifer into the fresh water producing zone of the aquifer. Although the report stated that there would be no objection to permitting an allocation on the order of 7.5 acre feet per year, which was the equivalent to the water crop, it was not recommended because such an allocation would do little to meet the applicant's needs for irrigation water (Exhibit 6, Composite Exhibit 20). Recognizing the need for further studies to support its application, Lost Tree hired a firm of consulting groundwater geologists and hydrologists to conduct an investigation of potential sources of irrigation water for both the John's Island and the Wabasso sites. The study confirmed prior conclusions that it was not practicable or feasible to develop the necessary irrigation water from sources available at John's Island. As to the Wabasso area, the report found that the shallow aquifer was not being fully utilized and that extraction of the proposed quantity of water would not exceed the capacity of the aquifer to provide it. It also determined that the presence of a continuous layer of impermeable clay within the Hawthorn formation effectively separates the Floridan from the shallow aquifer. No interference in the water levels of the Floridan aquifer should occur nor is it likely there would be salt water intrusion into the shallow aquifer. However, based on the formulation of a "mathematical model," it was predicted that the proposed withdrawal could adversely affect existing shallow wells within a few hundred feet of the applicant's well field by "drawdown" which could lessen the pumping ability of centrifugal pumps. Nearby existing wells, such as those located in a trailer park immediately west of Lost Tree's well field, could lose suction in pumping and thereby owners might experience delay in extracting water from the wells (Testimony of Amy, Exhibits 4, 8). Although one Wabasso resident who owns property near Lost Tree's wells has experienced a decrease in pressure in her well and poor quality water, and another nearby resident's well went dry, there is no clear evidence that Lost Tree's drilling of its two wells and consequent testing thereof caused these problems. Testimony of other Wabasso residents expressed their apprehension as to possible salt water intrusion and unavailability of water in the shallow aquifer if the requested withdrawal is approved. Other residents and public witnesses challenged the fairness of permitting one land owner to deplete local water supplies by withdrawals for transport to another area for recreational purposes (Testimony of Chesser, McPherson R., Pangburn R., Jackson, Mrs. S.B., Kale, Stout, Wintermute, Pangburn, K., Bidlingmayer, Willey, Gertzen). The District Staff Report, dated July 28, 1976, as supplemented by an addendum, dated August 30, 1976, reviewed the hydrogeological study submitted by the applicants and concluded that withdrawal of a specified amount of water from Lost Tree's Wabasso wells would represent a reasonable and beneficial use of the resource that did not appear to harm either the resource or existing users. It calculated the "crop requirement" for the golf courses on the basis of 135 acres. Testimony at the hearing established that the area required to be irrigated was only 70 acres. Consequently, the report's recommendation as to the annual water allocation for golf course irrigation was scaled down accordingly. Recommendations as to daily withdrawals were based upon the maximum billing by the City of Vero Beach for a 22-day period in January and February, 1975, plus a 20 percent allowance to provide a reasonable degree of operational flexibility. The conclusion of the staff that the withdrawal would not harm existing users is questionable in the light of the applicant's own hydrogeological study and testimony of its experts (Testimony of Winter, Exhibits 6,7,22). The Staff Report recommended that certain conditions be imposed upon any issuance of the requested permit. The following findings are made as to the reasonableness of such proposed conditions: Annual allocation of no more than 51.044 million gallons. FINDING: Reasonable. This permit shall expire 5 years after permit issuance. FINDING: Reasonable. The use may require reevaluation based upon developing needs of the area of withdrawal for higher priority uses of the resource. The total maximum monthly withdrawal from the two wells in Wabasso shall not exceed 6.931 million gallons. FINDING: Reasonable. The total daily withdrawal from the two wells in Wabasso shall not exceed 378,000 gallons. FINDING: Reasonable. Daily pumpage on a monthly basis shall be reported to the District during the following month. This data must be obtained through the use of an in line totalizing meter or meters at the well field. FINDING: Reasonable. Prior to the initiation of any pumping from the wells in Wabasso the permittee must survey all existing wells (with the owners' permission) located within 800 feet of each of these wells. Should it be determined that the permittee's pumping as recommended may adversely affect an existing well the permittee is to be held responsible for making timely corrective measures as deemed necessary at no expense to the owner, in order to preserve the water supply capability of that facility. A complete and detailed report of the survey and corrective measures taken by the permittee shall be submitted to the District. The District will then issue a notice authorizing the permittee to begin pumping as required. FINDING: Unreasonable. Although it is conceded by the applicants that adverse effects upon nearby wells may well occur, attempts to make determinations as to actual effects prior to full operation of Lost Tree's wells would only be speculative in nature. It is noteworthy in this regard that upon issuance of a temporary authorization to Lost Tree to withdraw water commencing in August, 1976, a similar precondition was imposed with a report of a survey and corrective measures taken to be submitted to the District prior to authorization to begin pumping. A cursory survey was performed by a representative of Lost Tree that consisted merely of attempting to locate surrounding wells by off-premises observation. No attempt was made to contact well owners or to obtain information as to the types of pumps on the wells. Such a survey is patently inadequate for the purposes desired by the District and it is considered impracticable and onerous to saddle the applicant with the burden of such a condition. Although withdrawals of water under the temporary permit commenced on September 18, 1976, and continued thereafter, there is no evidence that any complaints were registered by adjacent well owners as a result of the withdrawals (Testimony of Pearson, Exhibits 13, 14). For a period of 18 months after the first full week of operation in which no substantive complaints of adverse impact are received by the District, the permittee must assume full responsibility for taking the appropriate corrective to rectify any adverse impact their withdrawals create on any existing users within the area influenced by their withdrawal. Upon receiving a substantive complaint of adverse impact upon an existing user, the Executive Director of the District will issue a notice prohibiting any further withdrawals from the wells in Wabasso until corrective measures are taken by the permittee at no expense to the existing user, or until the permittee proves that their withdrawal is not the cause of the problem. The Executive Director of the District will issue a notice to resume withdrawals when the District has been satisfied that the situation is remedied. FINDING: Reasonable in part. The condition should be modified to extend the period of the permittee's responsibility for corrective action as to adverse impact on existing users to the entire life of the permit rather than for a period of only 18 months. Further, the District's prohibition of withdrawals after the receipt of a complaint is arbitrary and inconsistent with the method of administrative enforcement procedures as specified in Section 373.119(1), Florida Statutes. To help define the actual impact of the permittee's withdrawal a total of at least seven observation wells shall be installed. The observation wells shall be located between the permittee's wells and Indian River, two shall be located to the west and the remaining two shall be located either to the north or south of the permittee's wells. The locations and depths of these wells shall halve District concurrence. A continuous water level recording device shall be installed on one off these wells. FINDING: Reasonable. Although the installation and monitoring of a number of observation wells imposes a financial burden on the applicants, it is considered a proper requirement to assist in determining the impact of any withdrawal. The time for installation and specifications thereof should be set forth in any permit issued. Hydrographs from the recording device on one of the observation wells and from weekly hand measured water levels on the remaining observation wells shall be submitted to the District on a monthly basis. This data shall be submitted in the month following the period of record. All water level data shall be measured and recorded to the nearest hundredth of a foot and referenced to mean sea level. FINDING: Reasonable. By acceptance of this permit the permittee acknowledges that this permit confers no prior right to the permittee for the use of water in the amount allocated and for the purpose stated. FINDING: Unreasonable. The condition is ambiguous and involves legal aspects that are not proper for determination at this time. Any future application involving the use of the withdrawal facilities permitted herein, shall be considered as an application for a new use and it shall be reviewed accordingly. FINDING: Unreasonable. See comment in I above. All existing Floridan wells located on the applicant's properties must be abandoned in accordance with the current applicable standards of the Department of Environmental Regulation. Abandonment procedures must be carried out within 6 months of the date of issuance of this permit. FINDING: Unreasonable. The abandonment of existing Floridan wells involves subject matter not embraced within the application. An officer of the Lost Tree Village Corporation shall submit with each report required by the District a sworn and acknowledged affidavit that the report reflects the actual measurements or readings taken. FINDING: Reasonable. The Permittee shall obtain a water sample from a pumping well at the Wabasso well field site once a month, within five days of the end of the month. This sample shall be analyzed for chloride content, and the results reported to the District within 14 calendar days after collection. Should the District determine that a significant change has occurred in the chloride content of the water being withdrawn from the Wabasso well field, the District shall initiate a new review of the application. FINDING: Reasonable. Upon installation of the observation wells, a water sample shall be obtained from these wells and analyzed for the following parameters: Chloride Total Dissolved Solids Conductivity Sulfate Calcium Magnesium Sodium Bicarbonate This analysis shall be submitted to the District within 14 days after collection. During the last five days of the months of May and November of each year, during the duration of this permit, the permittee shall obtain one water sample from each of the installed observation wells. These samples shall be analyzed for Chloride content, and the results reported to the District within 14 days after collection. FINDING: Reasonable. If the permittee can demonstrate to the satisfaction of the District that the groundwater withdrawn by the south golf course well point system is no longer suitable for the irrigation of the golf course, the annual allocation shall be increased to 82.942 million gallons. FINDING: Unreasonable. Future needs should be the subject of modification of permit terms at an appropriate time, pursuant to section 373.239, F.S. An emergency authorization was issued to the applicants by the governing board of the District on August 30, 1976. This authorization contains certain special conditions including a requirement to conduct and submit a preauthorization survey and report concerning existing wells located within 800 feet of the applicant's wells. In addition, a condition of the authorization was that no withdrawals shall be made unless the City of Vero Beach had ordered the applicant to stop the use of water from its system for golf course irrigation. The evidence shows that neither of these conditions was met by the applicant, but yet withdrawals were made during the month of September, 1976 without District authorization (Testimony of Winter, Rearson, Exhibit 13). The applicant's disregard of these requirements indicates the need for a further special condition if a permit is granted, to ensure that adjacent land owners are protected in the event of adverse effects upon their water supply. To accomplish that, it is found that the following additional condition is reasonable and necessary: P. The Board shall require the applicant to furnish a bond in an appropriate amount, as authorized by Rule 16K-1.061, F.A.C. It is found that insufficient evidence has been presented to determine the merits of the request of the Town of Indian River Shores for an emergency water supply from the Wabasso wells.
Recommendation That a consumptive water use permit, with conditions as specified herein, be issued to applicant Lost Tree Village Corporation for the irrigation of its two golf courses at John's Island.

The Issue The issue is whether the Southwest Florida Water Management District (District) should issue water use permit (WUP) No. 2004912.006 to the City of Lakeland (City), and if so, how much water should be allocated under the permit and what conditions should be imposed on the allocation, particularly in regard to withdrawals from the City's Northeast Wellfield (NEWF).
Findings Of Fact Introduction This is an unusual case in that the District gave notice of its intent to issue a permit that the City does not want and that the District staff testified that the City is not even entitled to based upon the information submitted prior to and at the final hearing. That said, there is no disagreement between the parties that a permit should be issued to the City. Indeed, despite the District Staff's testimony that the City failed to provide “reasonable assurances” prior to or at the final hearing on a variety of issues, the District takes the position in its PRO that a permit should be issued to the City, subject to various conditions and limitations. There is also no disagreement between the parties that the permit should include an allocation of 28.03 mgd from the City’s Northwest Wellfield (NWWF). The main areas of disagreement between the District and the City are the duration of the permit; the total allocation of water under the permit; and, perhaps most significant, the total allocation from the NEWF. Parties The City is an incorporated municipality located in Polk County. The City is within the boundaries of the District and is within the Southern Water Use Caution Area (SWUCA) designated by the District. The City is the applicant for the WUP at issue in this case, No. 20004912.006. The City operates a public water utility that provides potable water and wastewater services to customers in and around the City. The utility’s water service area extends beyond the City limits into surrounding unincorporated areas of Polk County. The District is the administrative agency responsible for conservation, protection, management and control of the water resources within its geographic boundaries pursuant to Chapter 373, Florida Statutes, and Florida Administrative Code Rule Chapter 40D. The District is responsible for reviewing and taking final agency action on the WUP at issue in this case. Stipulated Facts The parties stipulated that the City’s substantial interests have been adversely affected by the District’s intent to issue the proposed permit, and that the proposed permit is different from the permit that the City applied for. The parties also stipulated that there is reasonable assurance that the City’s proposed water use will not interfere with a reservation of water as set forth in Florida Administrative Code Rule 40D-2.302; that the proposed use will not significantly induce saline water intrusion; that the proposed use will incorporate the use of alternative water supplies to the greatest extent practicable; and that the proposed use will not cause water to go to waste. The City’s Wellfields Overview The City obtains the water that its water utility provides to its customers from two wellfields, the NWWF and the NEWF. The NWWF is located north of Lake Parker in close proximity to Interstate 4 and Kathleen Road. It provides water to the Williams Water Treatment Plant, from which the water is distributed throughout the City water utility’s service area. The NWWF is located on the Lakeland Ridge, which is a geographic feature that is approximately 250 to 260 feet above sea level. The Lakeland Ridge has a thick clay intermediate confining unit that isolates the surficial aquifer from the underlying aquifers. The NEWF is located to the north of Interstate 4, adjacent to Old Polk City Road. It provides water to the Combee Water Treatment Plant (Combee), from which the water is distributed throughout the City water utility’s service area. The NEWF is located at an elevation of approximately 135 feet above sea level. The surficial aquifer at the NEWF is relatively thin, and the intermediate confining unit at the NEWF is not as thick as it is at the NWWF. The Upper Floridan Aquifer (UFA) begins at approximately 65 below land surface at the NEWF. The City’s water treatment plants are traditional lime softening plants and are not able to treat brackish groundwater or surface water to the extent necessary for human consumption. It would be cost-prohibitive to implement a process to treat brackish water at the plants. Relevant Permitting History The City’s water utility has been in operation for more than 100 years, and the NWWF has been in operation since at least the early 1980’s. The earliest permit for the NWWF contained in the record is permit No. 204912, which was issued by the District in January 1987. The permit authorized average annual withdrawals of 28.3 mgd, and had an expiration date of January 1993. The NEWF was first permitted by the District in December 1989. The permit, No. 209795.00, authorized the City to pump an average of 9.0 mgd from the NEWF. The permit had a six-year duration, with a December 1995 expiration date. The permits for the NWWF and the NEWF were combined into a single permit in October 1993. The permit, No. 204912.03, authorized the City to pump a total of 28.1 mgd, with 9.0 mgd from the NEWF. The permit had a 10-year duration, with an October 2003 expiration date. In December 2002, the City's WUP was administratively modified pursuant to the District’s SWUCA rules. The modified permit, No. 20004912.004, did not change the permitted quantities at the NEWF or the 2003 expiration date, but the total allocation was reduced to 28.03 mgd. In October 2003, prior to the expiration of the existing permit, the City submitted an application to renew and modify its WUP permit. The application requested a 20-year permit with a total allocation of 32.8 mgd, with up to 16.0 mgd from the NEWF. During the permit review process, the City amended its application to increase the requested total allocation by 4.0 mgd (from 32.8 mgd to 36.8 mgd) and to decrease the requested duration of the permit by five years (from 2023 to 2018). The 36.8 mgd requested by the City was to be allocated between the NWWF (28.03 mgd) and the NEWF (8.77 mgd). The City supplemented its application during the permit review process in response to multiple requests for additional information and clarification from the District. The information provided by the City in support of the application is extensive; the “permit file” received into evidence consisted of approximately 2,500 pages, and the entire file is approximately twice that size.2 The review process culminated in what the District staff considered to be a “negotiated permit”3 that would initially authorize pumping of 33.03 mgd, with 28.03 from the NWWF, 1.5 mgd from the NEWF, and 3.5 mgd from a production well to be constructed at Combee. The proposed permit includes a phasing schedule that would allow for increased withdrawals -- up to 35.03 mgd total and 4.0 mgd from the NEWF4 -- if the City is able to demonstrate to the District’s satisfaction that the increased pumping will not cause adverse environmental impacts. The District gave notice of its intent to issue the proposed permit on December 29, 2006, and the permit was placed on the “consent agenda” for the District Governing Board’s meeting on January 30, 2007. On January 23, 2007, before the proposed permit was considered by the Governing Board,5 the City timely filed a petition challenging the proposed permit. The petition alleges that the proposed permit does not allocate sufficient water to meet the City's projected population demands in 2018 and that it does not allocate water quantities from the NEWF and the NWWF in the manner requested by the City. The NEWF The NEWF is approximately 880 acres in size. Wetlands comprise approximately half of the site. The NEWF is located within the boundaries of the Green Swamp, which is an area of critical state concern (ACSC) designated under Chapter 380, Florida Statutes. The Green Swamp is a hydrologically and environmentally important feature of central Florida encompassing thousands of acres of cypress wetlands, marshes, and forests. In 1992, a task force recommended that public water supply wellfields “of capacity greater than 1.8 mgd (average 3.6 mgd maximum)” from the UFA be discouraged in the Green Swamp ACSC in favor of wells from the Lower Floridan Aquifer in order to “mitigate drawdown impacts to the surficial aquifer system and resulting dehydration of wetlands . . . .” There is no evidence of that recommendation being formally adopted by the District or any other governmental agency, and the District does not have more stringent permitting criteria for WUP applications in the Green Swamp, except that it considers potential adverse impacts to all isolated wetlands and not just those larger than one-half acre in size.6 The City installed five 16-inch production wells at the NEWF, along with a number of associated monitoring wells. The production wells, which are cased to approximately 120 feet with a total depth of approximately 750 feet, pump water from the UFA. Pumping at the NEWF started in October 2005. The City has been pumping 4.0 mgd from the NEWF since that time. The City has spent over $34 million to bring the NEWF into service. The costs directly related to the acquisition of the NEWF site and the installation of the wells at the site account for approximately $7.6 million of that amount; the remainder of the costs are for associated infrastructure, such as the installation of water lines from the NEWF site and the construction of Combee. The wetlands on the NEWF site are predominantly isolated cypress wetlands, although there are some connected systems. Isolated wetlands are more susceptible to impacts from water deprivation than are connected wetland systems. The uplands on the NEWF site consist primarily of open pasture and fields and areas of planted pines. Extensive drainage improvements were constructed on the NEWF site between 1941 and 1980 when the site was being used as improved pastureland for cattle grazing and managed woodland for logging and silviculture. The improvements included the construction of a network of drainage ditches, culverts, roads, a grass landing strip, and a gas pipeline. The intent and effect of the drainage improvements was to remove surface water from the onsite wetlands. Historical aerial photographs show that these efforts were successful. The wetlands on the NEWF were adversely impacted by the drainage improvements, but for the most part, they are still functioning, albeit low-quality wetlands. The extensive ditching on the NEWF site continues to have an adverse impact on the wetlands even though the ditches have not been maintained and do not function as efficiently as they once did. The planted pine trees on the NEWF site may also be adversely affecting the wetlands through increased evapotranspiration from the surficial aquifer. However, the evidence was not persuasive regarding the extent of the impact from evapotranspiration. The present condition of the wetlands at the NEWF is not the result of recent activity. The biological indicators in the wetlands (e.g., adventitious roots on cypress trunks, large oak trees in the wetlands, red maple trees in areas that had at one time been dominated by cypress trees) show that the degraded condition of the wetlands dates back decades. The progressive draining and degradation of the wetlands caused by the ditching and other drainage improvements constructed on the NEWF site is apparent in the historic aerial photographs of the site. The size of the wetlands and the “hydrologic signatures” (e.g., standing water around the rims of wetlands and across the site, extensive cypress canopies, etc.) visible on earlier aerial photographs are less visible or non- existent in more recent aerial photographs. The wetlands on the NEWF site have shown no biological indicators of impacts from the pumping at the NEWF that started in October 2005. This does not necessarily mean that the pumping is not impacting the wetlands because the parties' experts agree that it can take many years for such biological indicators to appear. The more persuasive evidence establishes that the historical drainage improvements on the NEWF site were the primary cause of the degraded condition of the wetlands.7 The more persuasive evidence also establishes that unless altered, the drainage improvements on the NEWF site will continue to have an adverse effect on the wetlands. The City proposed a conceptual Wetland Improvement Plan (WIP) that is designed to restore and enhance the wetlands on the NEWF. A central component of the WIP is the reengineering and alteration of the drainage features by installing “ditch blocks” in some areas and culverts in other areas. The WIP also includes not replanting the pine trees on the NEWF site once the existing planted pines are harvested. The ditch blocks and other modifications to the drainage features are intended to hold water on the NEWF site and redirect it to the wetlands. This will help to hydrate the wetlands, increase soil moisture levels, and allow more water to percolate into the surficial aquifer following rain events. The District staff expressed some concerns with the City’s WIP at the final hearing, but acknowledged that the plan’s “conception . . . has a lot of merit.” Indeed, in its PRO, the District recommends the “installation of ditch blocks and similar measures at the [NEWF] site.” The WIP, if properly implemented, has the potential to enhance the wetlands by returning them to a more natural condition. The City will likely need an Environmental Resource Permit (ERP) from the District before any system of ditch blocks can be installed. The details of the WIP can be worked out during the ERP permitting process.8 A good monitoring plan is part of providing reasonable assurances. The parties agree that a monitoring plan should be included as a permit condition, and the EMMPs attached to the parties’ respective PROs appear to be materially the same. The City has monitored the wetlands at the NEWF since 1994, pursuant to a specific condition in the 1993 WUP permit. The methodology used by the City to monitor the wetlands was approved by the District, and despite the fact that the City has submitted biannual monitoring reports to the District for almost 14 years, the District expressed no concerns regarding the methodology or results of the monitoring until recently. The District commenced its own wetland assessment procedure at the NEWF in May 2007, which included setting “normal pools” in several of the wetlands. “Normal pool” describes the level at which water stands in a wetland in most years for long enough during the wet season to create biological indicators of the presence of water. The establishment of normal pools was part of the District’s efforts to establish the “existing natural system” against which any post-withdrawal adverse impacts at the NEWF would be measured in accordance with Section 4.2 of the Basis of Review for Water Use Permit Applications (BOR).9 Normal pools could not be established in several of the wetlands because there was no measurable standing water above the surface in the wetland. District staff observed similar conditions –- i.e., no standing water in the wetlands –- on at least one occasion following a significant rain event prior to the start of pumping at the NEWF. The District does not have a rule governing the setting of normal pools, but the City’s experts did not take issue with the normal pools set by the District or the methodology used by the District to set the normal pools. The EMMP proposed by the City is an extensive monitoring plan that incorporates a series of onsite monitoring wells, wetland monitoring stations for vegetation and hydrogeology, monitoring of pumping rates and pumping data, and monitoring of rainfall data. The EMMP will make use of the extensive data that has been collected on the NEWF site since the 1990’s as well as the normal pools set by the District, and if properly implemented, the EMMP will detect any potential adverse impacts as they occur to allow for remedial mitigation. The District staff acknowledged at the final hearing that the EMMP proposed by the City “with some minor modifications” is an appropriate plan to monitor changes in the wetlands at the NEWF. The necessary "minor modifications" were not explained at the final hearing, and as noted above, there does not appear to be any material difference in the EMMPs attached to the parties’ respective PROs. The Green Swamp is generally viewed as a “leaky” area, with little or no confinement between the surficial aquifer and the Floridan aquifer. Regional data, including studies by the United States Geologic Survey (USGS) and the District, reflect that the NEWF is located in a “transitional area” between areas of little or no confinement to the north, northwest, and east of the NEWF and areas of thicker confinement to the south. However, at least one study (published in 1977 USGS report) shows the NEWF in an area designated as "poor" for its relative potential for downward leakage. Regional data may be used to gain knowledge about the aquifer properties at a potential well site, but such data is not a valid substitute site-specific data. Indeed, the location of the NEWF in a “transitional area” makes site-specific data even more important. The City used geologic cross-sections (e.g., soil borings and core samples) at the NEWF to determine the site’s lithologic characteristics. By contrast, the District relied primarily on USGS reports and other regional data to postulate as to the lithologic characteristics of the NEWF. As a result, the City’s position regarding the lithologic characteristics of the NEWF was more persuasive than the District’s position. The lithology of the NEWF site consists of a shallow, sandy surficial aquifer, which extends to a depth of 3 to 5 feet, proceeding downward to sandy clay and clay sand semi- confining layers, alternating with impermeable clay units, interspersed with an intermediate aquifer composed of sandy clays and clay sands that contain water, proceeding downward to the limestone of the UFA. The presence of clay layers between the intermediate aquifer and the UFA, together with clay layers between the intermediate aquifer and the surficial aquifer, provide two layers of protection between the pumped aquifer and the surficial aquifer and wetlands, and serve to ameliorate any impacts to the surficial aquifer caused by withdrawals from the UFA. “Leakance” is a measure of vertical conductivity that describes the rate at which water flows through a confining unit. As a result, leakance is one of the most important factors to consider when modeling surficial aquifer impacts and potential wetland impacts from groundwater pumping. Generally, a higher leakance value is an indication of a “leakier” system with less confinement between the surficial aquifer and the UFA. The “leakier” the system, the greater the impacts of pumping on the surficial aquifer will be. The District contends that the confining unit underlying the NEWF is “leaky” and that the pumping at the NEWF is likely to directly and adversely affect the onsite wetlands. However, the more persuasive evidence establishes that the lower leakance value derived by the City based upon the site-specific lithology of the NEWF and the data from the aquifer performance tests (APTs) conducted at the NEWF is more accurate than the higher leakance value urged by the District. The purpose of an APT is to determine the hydrologic parameters of an aquifer. In particular, an APT is used to determine the transmissivity, leakance, and storage values of the aquifer. Transmissivity is a measure of how easily water flows through the ground, and storage is a measure of the amount of water in the porous spaces of the aquifer. Generally, a higher transmissivity value and a lower storage value indicate better confinement. There have been three APTs conducted at the NEWF. The first APT (APT-1) was conducted in 1989 as part of the initial permitting of the NEWF. A high transmissivity value and a low storage value were calculated in APT-1. A leakance value was not calculated. The results of APT-1 were presented to the District to justify the City’s request to pump 9.0 mgd from the NEWF, which the District approved. The 1993 permit combining the NWWF and the NEWF required the City to conduct a long-term APT in order to “determine the leakance parameter between the surficial and intermediate aquifers and the leakance parameter between the intermediate and Upper Floridan aquifers.” The permit stated that if the hydrologic parameters obtained in the APT were different from those used in the model submitted in support of the initial WUP, the City would have to revise the model and, if necessary, modify the WUP to reduce withdrawals. This second APT (APT-2) was a seven-day test conducted by the City in January 2001 in accordance with a methodology approved by the District. An “exceedingly low” leakance value of 4.5 x 10-4 gallons per day per cubic foot was calculated in APT-2. The transmissivity and storage values calculated in APT- 2 were essentially the same as the values calculated in APT-1. The District expressed concerns with the results of APT-2, and in December 2001, the District advised the City that it should “proceed with caution during the planning of infrastructure (pipelines) for the [NEWF]” because the “wellfield may not be able to produce the volume of water the City has stated that would like from the wellfield, without causing adverse impacts.”10 Based upon these concerns, the District conducted an APT (APT-3) at the NEWF in April and May 2003. The parties’ experts agree that data from APT-3 is reliable, but the experts disagree in their interpretation of the data, particularly in regards to the leakance value. The City’s experts calculated a leakance value of 1.4 x 10-4 feet per day per foot, which is a low leakance value. The expert presented by the District, Dann Yobbi, calculated a higher leakance value of 3.4 x 10-3 feet per day per foot, which suggests relatively “leaky” aquifer. The leakance value calculated by the City’s experts is more persuasive than the value calculated by Mr. Yobbi because Mr. Yobbi did not “de-trend” the data from APT-3 based upon the general declines in water levels occurring at the time of APT-3. Indeed, Mr. Yobbi testified that he is in the process of revising his report on APT-3 to address this issue and he acknowledged that the surficial aquifer showed only a “slight response” to the pumping during APT-3. The leakance value calculated by the City’s experts in APT-3 is consistent with the leakance value calculated in APT-2. The transmissivity and storage values calculated in APT-3 are also consistent with the values calculated in APT-1 and APT-2. The reliability of the leakance values and other aquifer parameters calculated by the City’s experts for the NEWF is confirmed by water level data compiled by the City pursuant to the monitoring requirements in the existing WUP. The water level data was collected from monitoring wells at the NEWF in the surficial aquifer, the intermediate aquifer, and the UFA. The City began collecting this data in 1994 and it continues to collect and report the data to the District as required by the existing WUP. The water level monitoring data reflects that the surficial aquifer at the NEWF responds almost immediately to rain events. By contrast, the intermediate aquifer and UFA show a more subdued response to rainfall events, which is indicative of good confinement, especially between the UFA and the surficial aquifer. The water level monitoring data shows that rainfall or lack of rainfall is the major controlling factor relative to the rate of surficial aquifer recharge at the NEWF. The water level monitoring data since pumping began at the NEWF shows that the pumping at 4.0 mgd is having a minimal impact on the surficial aquifer at the NEWF. Indeed, the more persuasive evidence establishes that the general decline in water levels that has been observed in the monitoring wells at the NEWF over the past several years is more likely than not attributable to the severe drought in the area and the onsite drainage features, and not the pumping at the NEWF.11 Moreover, the more persuasive evidence shows that following the start of pumping at the NEWF in October 2005, the water levels in the surficial, intermediate, and Floridan aquifers returned to the historic patterns of up and down response to rainfall events shown throughout the thirteen-year period of record: the surficial aquifer fills quickly (as it receives the rainwater directly) and empties quickly (through a combination of surface drainage, evapotranspiration, evaporation, and leakage), while the UFA responds with more gradual rising and falling (as water enters the aquifer through recharge areas and slowly percolates into the aquifer through more confined areas). The analysis of the water level data collected during APT-3 showed a similar trend in the rates of decline in the surficial aquifer as were reflected in the hydrographic record of the monitoring well data collected by the City since 1994. The natural, post-rainfall rate of decline under non-pumping conditions was consistent with the rate of decline observed during pumping conditions in APT-3. In sum, the interpretation of the water level data by the City’s experts was more persuasive than the interpretation by the District’s experts. Modeling of Predicted Drawdowns and Impacts The City utilized two different models to predict drawdowns from the proposed pumping at the NWWF and NEWF: the USGS “Mega Model” and the District’s District-Wide Regulation Model (DWRM). The models incorporated regional data published by the USGS and the District as well as site-specific data from the NEWF, including the lithologic information collected through soil borings and the hydrologic parameters of the aquifers calculated in APT-3. The models were calibrated and de-trended to remove “background conditions” (e.g., regional water level declines) so that the models would only show the predicted effects of the pumping. Once the calibration was complete, the models were run to simulate the effect of the pumping on the groundwater flows in the area. The models produced contour maps that showed the predicted drawdowns in the surficial aquifer as a result of the pumping. The USGS Mega Model predicted that pumping the NEWF at 8.77 mgd would result in drawdowns of approximately 0.5 foot in the surficial aquifer in and around the NEWF. The DWRM model predicted a 0.18 foot drawdown in the surficial aquifer in and around the NEWF when pumping the NEWF at 4.0 mgd, and a drawdown of 0.4 foot when pumping at 8.77 mgd. The same models were used to predict the “cumulative” drawdowns by taking into account pumping by existing legal users as well as the pumping at the NWWF. The cumulative models assumed pumping of 36.8 mgd from the City’s wellfields. The USGS Mega Model predicted that cumulative drawdowns in the surficial aquifer in and around the NEWF would be an additional 0.3 feet, with 8.77 mgd of pumping at the NEWF. The DWRM model predicted that the cumulative drawdowns in the surficial aquifer in and around the NEWF would be 0.4 foot with 4.0 mgd of pumping at the NEWF, and 0.6 foot at 8.77 mgd of pumping at the NEWF. The City utilized the 1995 data set of existing legal users in its cumulative DWRM modeling because that was the data set provided by the District. The difference between the 1995 data set and the more current 2002 data set is on the order of 20 mgd, which is inconsequential in comparison to the 1.1 billion gallons per day of withdrawals included in the model that are spread over the geographic extent of the District. The predicted drawdowns in the surficial aquifers in and around the NEWF would be considerably greater if the hydrologic parameters calculated by Mr. Yobbi were used in the DWRM model. For example, the District’s modeling predicted drawdowns between 1.0 and 1.2 feet in the surficial aquifer in and around the NEWF when pumping 1.5 mgd from the NEWF, 3.5 mgd from Combee, and 28.03 mgd from the NWWF. The wetlands experts presented by the parties agreed that the level of drawdown predicted by the City at the NEWF has the potential to adversely impact the wetlands on the site. The experts also agreed that there is no bright line as to the amount of drawdown that will adversely impact the wetlands. The City’s expert, Dr. Michael Dennis, testified that drawdowns in the surficial aquifer between 0.18 foot and 0.5 foot “probably” would not affect the wetlands at all, or at least “not measurably.” He also testified that drawdowns between 0.5 foot and one foot “are the drawdowns that you need to be concerned about.” The District’s expert, John Emery, testified that a drawdown in the surficial aquifer of 0.4 foot “could” adversely affect the wetlands if no mitigation is provided, but that a drawdown of 0.2 to 0.3 foot might not.12 The WIP is expected to increase the amount of water that gets to the wetlands on the NEWF site. However, the extent to which the WIP will increase the water levels in the wetlands and offset the predicted drawdowns in the surficial aquifer is unknown at this point. Limiting pumping at the NEWF to 4.0 mgd is reasonable and prudent based upon the uncertainty regarding the effectiveness of the WIP and the experts’ testimony regarding the level of drawdowns that likely would, and would not, adversely affect the wetlands at the NEWF. In sum, the more persuasive evidence establishes that the drawdown predicted at 4.0 mgd of pumping –- 0.18 foot (individually) and 0.4 feet (cumulatively) –- is not likely to adversely impact the already significantly degraded wetlands at the NEWF, particularly if the WIP is properly implemented. Demand Projections The City did not use the full 28 mgd allocated under its existing WUP. It pumped only 21 mgd in the 12 months preceding October 2003, when the permit was scheduled to expire; it pumped only 26 mgd in 2006; and the pumping for 2007 was expected to be approximately 1 mgd lower than the pumping in 2006. The City's WUP application contained population and demand projections for different years in the future. For 2014 (the permit expiration date proposed by the District), the “functional population”13 of the service area was projected to be 183,264 and the average demand was projected to be 29.5 mgd; for 2023 (the original permit expiration date requested by the City), the projections were 203,721 people and 32.8 mgd; and for 2018 (the permit expiration date now requested by the City), the projections were 192,176 people and 30.9 mgd. The projections in the WUP application were prepared in 2003, and City's primary consultant, Charles Drake, testified that the data was “accurate” and “reliable.” However, more recent data shows that the population projections in the WUP application were slightly understated. The more recent data is contained in the “Water Services Territory Population Estimates and Projections” reports prepared by the City's utility department in March 2006 and March 2007. The reports include estimates of the functional population for prior years, and projections of the functional population for future years. The estimates reflect the “actual” population for a given year in the past, whereas the projections reflect the “expected” population for future years. The estimates and projections in these reports, like the projections in the WUP application, were prepared in accordance with the methodology contained in the BOR. The District did not take issue with the projections in the reports or the WUP application. The estimated functional population of the service area in 2003, 2004, 2005, and 2006 exceeded the population projected for those years in the WUP application. On average, the projected populations for each year understated the “actual” populations by approximately 3,500 persons.14 Likewise, the population projections for future years in the March 2007 report are higher than the population projections for the same years in the WUP application. For example, the report projects that the functional population of the service area in 2014 will be 191,208 (as compared to 183,264 in the WUP application), and that population in 2018 will be 203,247 (as compared to 192,176 in the WUP application). The City presented “revised” population projections at the final hearing in City Exhibit 140. The revised projections were based on the projections in the March 2006 report, but also included data from the “water allocation waiting list” that is part of the City’s concurrency management system that was created by the City in response to legislation passed in 2005 requiring local governments to allocate and approve requests for water for new development. The population projections in City Exhibit 140 are 234,959 in 2014; 247,390 in 2018; and 264,556 in 2023. These projections include an additional 43,471 persons related to new development in the concurrency management system, as well as the additional 2,600 to 3,000 persons projected per year in the WUP application and the March 2006 report. The City failed to establish the reasonableness of the revised population projections. Indeed, among other things, the evidence was not persuasive that the additional population attributed to the new development in the concurrency management system is not already taken into account, at least in part, in the annual population increases projected in the March 2006 report.15 The most reasonable population projections for the service area of the City's utility are those in the March 2007 report.16 The record does not contain demand projections directly related to the population projections in the March 2007 report. However, demand projections for those population projections can be inferred from the WUP application (City Exhibit 1(a)(2), at 0036) and City Exhibit 140 (at page 0015). The 2014 projected population of 191,208 in the March 2007 report roughly corresponds to the projected population for 2018 in the WUP application (192,176) for which the projected demand was 30.9 mgd; and it also roughly corresponds to the projected population for 2008 in City Exhibit 140 (193,001), for which the projected demand was 28.7. Thus, in 2014, it is reasonable to expect that demand will be between 28.7 and 30.9 mgd. The 2018 projected population of 203,247 in the March 2007 report roughly corresponds to the projected population for 2023 in the WUP application (203,721) for which the projected demand was 32.8 mgd; and it also roughly corresponds to the projected population for 2009 in City Exhibit 140 (201,983), for which the projected demand was 30.2 mgd. Thus, in 2018, it is reasonable to expect that demand will be between 30.2 and 32.8 mgd. The demand projections in the WUP for 2014 (29.5 mgd) and 2018 (30.9 mgd) fall within the range inferred for the populations in the March 2007 report. Thus, even though the population projections in the WUP application for 2014 and 2018 are understated, the demand projections for those years in the WUP are still reasonable. The demand projections in City Exhibit 140 –- 35.3 mgd in 2014 and 36.6 mgd in 2018 –- are overstated as a result of unreliable population projections upon which they are based. Other Issues Duration of Permit The 1987 permit for the NWWF had a six-year duration, as did the original 1989 permit for the NEWF. The 1993 permit had a 10-year duration, but that permit did not increase the amount of authorized withdrawals; it simply combined the authorizations for the NWWF and the NEWF into a single permit. In this case, the City is requesting a permit that expires in 2018, which was a 15-year duration at the time the application was filed, but now is a 10-year duration. The District is proposing a permit with a six-year duration, expiring in 2014. The District is authorized to approve a WUP with a duration of up to 50 years. The District’s rules provide that the duration of the permit is to be determined based upon “the degree and likelihood of potential adverse impacts to the water resource or existing users.” The District’s rules require that in order for the District to approve a permit with a duration of more than 10 years, the applicant is required to present sufficient facts to demonstrate that such a permit is “appropriate.” Section 1.9 of the BOR provides “guidelines” regarding the duration of permits. The guidelines in the BOR are not binding on the District, but the nearly identical language in Florida Administrative Code Rule 40D-2.321 is binding on the District. The BOR provides that a six-year permit is to be issued for renewal permits “with modification to increase the quantity withdrawn by more than or equal to 100,000 gpd or 10% or more of the existing permitted quantities, whichever is greater.” The BOR and Florida Administrative Code Rule 40D- 2.321(2)(b) also provide that a six-year permit is to be issued “where the potential for significant adverse impacts are predicted.” The renewal permit that the City is seeking requests an increase of 8.7 mgd (from 28.1 mgd to 36.8 mgd) over the existing permitted quantities, which exceeds the 10 percent threshold in Section 1.9 of the BOR. Moreover, there is a potential for significant adverse impact from the renewal permit that the City is seeking. Accordingly, a six-year permit is appropriate under the District’s rules and the guidelines in the BOR. The City failed to demonstrate why a longer permit duration is appropriate under the circumstances of this case. District staff testified at the final hearing that the permit term should be calculated from the date the permit is issued, which will be some point in 2008. Therefore, the permit should have an expiration date of 2014. Offsite Impacts The City used the modeling described above to predict the drawdown in the UFA from the proposed pumping in order to determine whether there will be any adverse impacts on existing legal users. The predicted drawdown in the UFA in the vicinity of the NEWF ranges from 1.6 feet to 2.4 feet with 4.0 mgd of pumping at the NEWF, and between 3.4 feet and 5 feet with pumping at 8.77 mgd. The predicted drawdown in the UFA in the vicinity of the NWWF ranges from 10.0 to 14.0 feet, with 28.03 mgd of pumping at the NWWF.17 These predicted drawdowns are not expected to have any adverse impacts on existing legal users that have wells in the UFA. Most permitted wells in the UFA use vertical turbine pumps, which can easily accommodate fluctuations in water levels of five feet or more. The City has not received any complaints from existing users since it began pumping 4.0 mgd at the NEWF in October 2005. The pumping at the NWWF, which has been ongoing for more than 20 years, has not caused any adverse impacts to existing legal users. The City is required under the existing WUP to respond to any adverse impact complaints from existing legal users, and it is required to implement mitigation, as needed. In short, City is required to do whatever is necessary (e.g., relocating or increasing capacity of pump, lowering pipes) to return any well impacted by the pumping to its prior function. The City did not evaluate the potential impacts of its proposed pumping on unpermitted wells because the District does not maintain a database of unpermitted wells. However, the City acknowledges that if its pumping impacts an unpermitted well, it will be obligated to mitigate those impacts in the same manner that it is required to mitigate impacts to existing permitted users. The predicted drawdowns for water bodies in the vicinity of the NWWF and the NEWF that have designated Minimum Flows and Levels (MFLs) -- Lake Bonny, Lake Bonnett, and the Cone Ranch wetlands -- are minimal, on the order of 0.1 foot. The City evaluated the impacts of pumping on contaminated sites listed by the Department of Environmental Protection (DEP) in the vicinity of the NWWF and NEWF. Based upon the results of the modeling conducted by the City, there is no reason to expect that pumping at the NWWF and/or NEWF will have any measurable impact on those sites or lead to pollution of the aquifer. Potential Impacts of NWWF Pumping The only concern expressed by the District with respect to the pumping at the NWWF relates to the potential environmental impacts of the pumping on Lake Bonny and Lake Bonnett. The City agreed to include those lakes in its EMMP. Combee Combee is located approximately four miles south of the NEWF. There is a relatively thick clay confining unit at Combee, which, according to the District, makes it a better location for water withdrawals than the NEWF. The District conducted an APT at Combee in 2006. The hydrologic parameters derived from the APT, and the “preliminary modeling” performed by the District show that the City may be able to withdraw at least 3.0 mgd from wells at Combee. The proposed permit authorized pumping of 3.5 mgd from Combee. The proposed permit also included a phasing schedule pursuant to which pumping at Combee would be decreased to 3.0 mgd if pumping at the NEWF reached 4.0 mgd. The City expressed an interest in obtaining water from Combee throughout the permitting process. However, the City represented at the outset of the final hearing that the Combee well is “off the table because the City wishes to maximize the withdrawal allocation from [the NEWF].” The City stated in its PRO that it is “willing to consider permitting a production well at [Combee] as a potential mitigation resource, should unexpected adverse impacts require the City to divert production to a back-up resource.” The District stated in its PRO that the Combee well is “available for mitigation purposes," and that the City “should be encouraged to apply for a WUP for withdrawals from Combee up to 3.0 mgd to provide additional mitigation for pumping from the [NEWF].” Pump rotation Rotation of pumping between the wells in a wellfield is a standard practice, and it can be an effective mitigation technique. The City utilizes well rotation programs at the NWWF and the NEWF in order to minimize the stress on the production aquifers. Rotating pumping between the production wells at the NEWF is particularly appropriate because several of the wells are located in very close proximity to wetlands. Rotating the pumping will help to minimize the potential for adverse impacts to the wetlands. The actual rotation schedule is an operational decision that is made based upon observed conditions at the wellfield site, rather than something that is typically included in the WUP. Conservation and Reuse The City has a four-tiered conservation rate structure, modeled after the District’s graduated water-rates prototype. The rate structure imposes higher unit costs as individual consumption increases, thereby discouraging wasteful uses of water. The City has a comprehensive leak detection program aimed at preventing the loss of water within the City’s water distribution system. This program has helped to reduce the per- capita per-day consumption rate for the City by reducing the volume of water that is wasted before it is delivered to the consumer. The City has implemented irrigation restrictions aimed at reducing the quantities of water used by domestic customers for lawn and garden watering. The per capita rate of water consumption is a measure of the effectiveness of a water conservation program; the lower the figure, the better. The City’s per capita rate has increased in recent years, but its adjusted gross per capita rate has decreased. The adjusted gross per capita rate takes into account “significant users,” which are defined as non-residential customers other than golf courses that use more than 25,000 gallons per day or that represent more than five percent of the utility’s annual water use.18 The City’s per capita rate in 2005 was 145.69 gallons per day, and its adjusted gross per capita rate in that year was 132.01 gallons per day. The adjusted gross per capita rate may not exceed 150 gallons per day within the SWUCA. Thus, the City will be required to continue its conservation programs (and implement additional programs, if necessary) to ensure that its adjusted gross per capita rate does not exceed 150 gallons per day over the life of the permit. A portion of the City’s treated wastewater is reused for cooling at the City’s McIntosh Power Plant pursuant to a permit from DEP under Chapter 403, Florida Statutes. The DEP permit, No. FL0039772 (Major), states in pertinent part: Industrial Reuse: Effluent is reused . . . as a non-contact cooling water at the City of Lakeland McIntosh Power Generating Plant. The volume of water used on a daily basis fluctuates on an as needed basis. There are no restrictions on the volume that can be routed to the reuse system. The power plant evaporates water in the cooling process or returns cooling water into the Glendale WWTP for final treatment in the manmade wetlands treatment system. The reuse in the power plant is not required as effluent disposal. . . . . The remainder of the City’s treated wastewater is “blended” with the water used at the power plant in order to meet the conductivity standards in the DEP permit and the conditions of certification for the power plant and/or directly discharged into an artificial wetland system that ultimately discharges to the Alafia River. Section 3.1 of the BOR (at page B3-2) provides that “Water Use Permittees within the SWUCA who generate treated domestic wastewater are encouraged to demonstrate that . . . 50% of the total annual effluent flows is beneficially reused.” (Emphasis supplied). The BOR lists a number of uses of treated wastewater that are considered to be beneficial reuse. The list includes “industrial uses for cooling water, process water and wash waters” and “environmental enhancement, including discharges to surface water to replace withdrawals.” The City’s use of treated wastewater for cooling at the McIntosh Power Plant is a beneficial reuse under the BOR. The treated wastewater directly discharged by the City into the artificial wetland system is not a beneficial reuse under the BOR because it is not replacing surface water withdrawals. The BOR requires all users within the SWUCA to investigate the feasibility of reuse, and requires the implementation of reuse “where economically, environmentally and technically feasible.” The City has not recently undertaken a study or otherwise evaluated the feasibility of increasing its reuse. The draft permit attached to the District's PRO includes a specific condition requiring the City to "provide a comprehensive study of reuse opportunities encompassing the [City's] water, wastewater, and electrical utilities systems" by January 1, 2009.
Recommendation Based upon the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the District issue WUP No. 2004912.006 with the terms and conditions contained in the draft permit attached to the District’s PRO, except that: The 2014 population referenced in the permit shall be 191,208; The adjusted gross per capita rate shall not exceed 150 gallons per day; Special Condition No. 2 shall be amended to authorize withdrawals from the NEWF at 4.0 mgd annual average and 4.8 mgd peak month, and the quantities listed in the Withdrawal Point Table for the NEWF wells shall be adjusted accordingly; Special Condition No. 4 shall be replaced with a reference to the EMMP and the conceptual WIP attached to the City’s PRO, and the list of monitoring stations in the EMMP shall be amended to include Lake Bonny and Lake Bonnet; and An additional specific condition shall be added encouraging the City to pursue a WUP for the Combee site for future water needs and/or for additional mitigation of the impacts of pumping at the NEWF.

The Issue Whether the Petitioner is entitled to the issuance of a water vending machine permit for a machine located at Herman's Meat Market, Nokomis, Florida, under the provisions of Section 381.295, Florida Statutes.
Findings Of Fact A water vending machine located at Herman's Meat Market, 227 West Albee Road, Nokomis, Florida, operating from a non-community water supply came to the attention of the Department's water vending machine permitting personnel in Tallahassee on March 9, 1987. At that time, Frank Dowdney, on behalf of Bottled Water Vending of Florida, had made application for issuance of a water vending machine permit at that location. Upon request of the Department in June, 1987, Mr. Dowdney had the well water tested to determine whether the water met community public water supply system standards as required in Chapter 10D-22.004(5) Florida Administrative Code. The water failed to meet the minimum standards as determined by the lab report dated July 22, 1987 of Thornton Laboratories Inc. There were four areas of deficiency, specifically, turbidity, radionuclides, iron, and total dissolved solids (T.D.S.). Mr. Dowdney did not provide any additional test results to the Department and did not receive a permit from the Department for this location. Subsequent to Mr. Dowdney's death in the fall of 1987, the water vending machine location at Herman's Meats was operated by Glacier Water Vending. In the summer of 1988, an agent of Glacier Water had notified departmental permitting personnel that the machine at this location was not in operation. Glacier Water Vending never requested a permit for this location. On September 7, 1988, Mr. McKinney, President of the Petitioner Clean Water Systems, Inc., became the operator of a new water vending machine at the Herman's Meats Location. Mr. McKinney submitted an application for a permit on September 6, 1988, which was denied on November 3, 1988. The reason for denial was that the water source at Herman's Meats had not been shown to be in compliance with community public water system standards. Neither Mr. McKinney nor Clean Water Systems, Inc., though aware of the predecessor operators at this location, had any ownership interest and had not been an employee of either Bottled Water Vending of Florida or Glacier Water Vending. A reverse osmosis system which had been installed on the source line from the well to the water vending machine subsequent to the 1987 testing was removed by Robert Miller of Glacier Water Vending. Mr. McKinney installed a new reverse osmosis system on the source line on September 7, 1988. The source water for a vending machine is the water just prior to entering the machine, which includes the well and any treatment processes between the well and the machine. The source water for Petitioner's vending machine has been processed through chlorination and one reverse osmosis system. This source water must meet minimum standards established for community public water supply systems. There are many different types of reverse osmosis systems. In general, a reverse osmosis system is a purification process intended to improve water quality. The degree of improvement in product water is affected by many factors including, but not limited to, feed water mineral concentration, feed pressure, feed water temperatures and Ph. It cannot be assumed that minimum water quality standards are being met just because a reverse osmosis system has been installed. The Department has no obligation to provide and/or pay for the chemical testing that is a prerequisite to the issuance of this water vending machine permit. Department personnel do perform required bacteriological and nitrate testing on the non-community well at Herman's Meats. There has been a pattern of noncompliance for bacteriological and chlorine residual levels at this location. The Department does not perform water vending machine testing at Herman's Meats and would only do so if there was a complaint. At the time of the hearing, there had been no complaints about the vended water there. The Petitioner has provided no test results from a state certified lab to the Department. The Petitioner has provided to the Department only test results from his own testing efforts which relate only to the total dissolved solids (T.D.S.) category. The test results generated by Mr. McKinney are not adequate for departmental permitting purposes. The only state certified chemical test results available to the Department on this location show that the source water did not meet minimum standards for community public water supply systems in 1987.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that Petitioner's application for a water vending machine permit be DENIED.

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
The Issue Whether SFP's revised application for a permit to construct a sewage treatment plant with percolation ponds should be granted or, for failure of SFP to give reasonable assurances that the plant will not cause pollution significantly degrading the waters of Gator Cove, be denied?
Findings Of Fact About 1,500 feet from Santa Fe Lake's Gator Cove, SFP proposes to build an extended aeration package sewage treatment plant to serve a "private club with restaurant and overnight accommodations," SFP's Exhibit No. l, to be built between the plant and the lake, on the western shore of Santa Fe Lake, just south of the strait or pass connecting Santa Fe Lake and Little Santa Fe Lake. The site proposed for the waste water treatment plant lies at approximately 177 or 178 feet above sea level, north of Earleton on county road N.E. 28 near State Road 200A, some three miles north of State Road 26, in unincorporated Alachua County, Section 33, Township 8 South, Range 22 East. SFP's Exhibit No. 1. Santa Fe Lake, also called Lake Santa Fe, and Little Santa Fe Lake, also called Little Lake Santa Fe, are designated outstanding Florida waters by rule. Rule 17-3.041(4)(i), Florida Administrative Code. Lake Santa Fe "is . . . the sixth largest non-eutrophic lake in the State of Florida . . . [and] the last remaining large non-eutrophic lake in Alachua County." (0.367). Recreation is a "beneficial use" of these waters. The Lakes Santa Fe are at an elevation of approximately 140 feet above sea level, and their level varies within a range of four feet. Input The proposed plant is to treat sewage generated by staff, by diners at a 150-seat restaurant, and by inhabitants of 150 lodge or motel rooms, comprising 100 distinct units. On the assumptions that 150 rooms could house 275 persons who would generate 75 gallons of sewage a day for a daily aggregate of 20,625 gallons, and that a 150-seat restaurant would generate 50 gallons of sewage per seat per day, full occupancy is projected to engender 28,125 gallons of sewage per day. This projection is based on unspecified "D.E.R. criteria; (5.35) which the evidence did not show to be unreasonable. Full occupancy is not foreseen except around the Fourth of July, Labor Day and on other special occasions. An annual average flow of between 15 and 20,000 or perhaps as low as 13,000 gallons per day is envisioned. (S.38) The proposed plant is sized at 30,000 gallons per day in order to treat the peak flow forecast and because package plants are designed in 5,000 gallon increments. Sluice-gate valves and baffling are to permit bypassing one or more 5,000 gallon aeration units so plant capacity can be matched to flow. The composition of the sewage would not be unusual for facilities of the kind planned. As far as the evidence showed, there are no plans for a laundry, as such, and "very little laundry" (S.37) is contemplated. The health department would require grease traps to be installed in any restaurant that is built. Gravity would collect sewage introduced into 2,000 feet of pipe connecting lodging, restaurant and a lift station planned (but not yet designed) for construction at a site downhill from the site proposed for the water treatment plant. All sewage reaching the proposed treatment plant would be pumped 3,000 feet from the lift station through a four-inch force main. Influent flow to the treatment plant could be calculated by timing how long the pump was in operation, since it would "pump a relatively constant rate of flow." (S.39) Treatment Wastewater entering the plant would go into aeration units where microorganisms would "convert and dispose of most of the incoming pollutants and organic matter." (S.40) The plant would employ "a bubbler process and not any kind of stirring-type motion . . . [so] there should be very little:; aerosol leaving the plant," (S.42) which is to be encircled by a solid fence. Electric air blowers equipped with mufflers would be the only significant source of noise at the proposed plant, which would ordinarily be unmanned. If one blower failed, the other could run the plant itself. A certified waste water treatment plant operator would be on site a half-hour each week day and for one hour each weekend. SFP has agreed to post a bond to guarantee maintenance of the plant for the six months' operation period a construction permit would authorize. (0.63) The proposed plant would not "create a lot of odor if it's properly maintained." Id. The specifications call for a connection for an emergency portable generator and require that such a generator be "provide[d] for this plant. . . ." (S. 43). The switch to emergency power would not be automatic, however. A settling process is to follow extended aeration, yielding a clear water effluent and sludge. Licensed haulers would truck the sludge elsewhere for disposal. One byproduct of extended aeration is nitrate, which might exceed 12 milligrams per liter of effluent, if not treated, so an anoxic denitrification section has been specified which would reduce nitrate concentrations to below 12 milligrams per liter, possibly to as low as 4 or 5 milligrams per liter. Before leaving the plant, water would be chlorinated with a chlorinator designed to use a powder, calcium hypochlorite, and to provide one half part per million chlorine residual in the effluent entering the percolation ponds. A spare chlorine pump is to be on site. The effluent would meet primary and secondary drinking water standards, would have 20 milligrams or less per liter of biochemical oxygen demand or, if more, no more than ten percent of the influent's biochemical oxygen demand, and total suspended solids would amount to 20 milligrams or less per liter. (5.294- 295). Half the phosphorous entering the plant would become part of the sludge and half would leave in the effluent. Something like ten milligrams per liter of phosphorous would remain in the effluent discharged from the plant into the percolation ponds. (5.202). Although technology for removing more phosphorous is available (S.298, 0.170-171), SFP does not propose to employ it. Allen flocculation treatment followed by filtration could reduce phosphorous in the effluent to .4 milligrams per liter, but this would increase the cost of building the treatment plant by 30 to 40 percent; and operational costs would probably increase, as well, since it would be necessary to dispose of more sludge. (0.170-172). SFP did agree to accept a permit condition requiring it to monitor phosphorous levels in groundwater adjacent to the proposed plant. (0.63). Land Application Three percolation ponds are planned with an aggregate area of 30,000 square feet. At capacity, the plant would be producing a gallon and a half of effluent a day for each square foot of pond bottom in use. The ponds are designed in hopes that any two of them could handle the output of effluent, even with the plant at full capacity, leaving the third free for maintenance. The percolation ponds would stand in the lakes' watershed, in an area "of minimal flooding, (S.30) albeit outside the 100-year flood plain. Santa Fe Lake, including Gator Cove, and Little Santa Fe Lake are fed by groundwater from the surficial aquifer. All effluent not percolating down to levels below the surficial aquifer or entering the atmosphere by evapotranspiration would reach the lake water one way or another sooner or later. If percolation through the soils underneath the percolation ponds can occur at the rate SFP's application assumes, effluent would not travel overland into Lake Santa Fe except under unusually rainy conditions, which would dilute the effluent. Whether the planned percolation ponds would function as intended during ordinary weather conditions was not clear from the evidence, however. In the event the ponds overflowed, which, on SFP's assumptions, could be expected to happen, if peak sewage flaw coincided with weather more severe than a 25-year rainfall, effluent augmented by rainwater would rise to 179.87 NGVD (S.34), then overflow a series of emergency weirs connecting the ponds, flow through an outfall ditch, drain into a depression west of the ponds, enter a grassed roadside ditch, and eventually reach Lake Santa Fe after about a half a mile or so of grass swales. (5.69). Sheet flow and flow through an ungrassed gulley in the direction of Gator Cove (0.154) are other possible routes by which overflowing waters might reach the lake. (0.263). Since the facilities the plant is designed to serve are recreational, wet weather would discourage full use of the facilities and therefore full use of the water treatment system. Effluent traveling over the surface into Gator Cove would wash over vegetation of various kinds. Plants, of course, do take up phosphorous, but they don't do it forever, and if you leave a plant system alone, it will come to a steady state in which there is no net storage of phosphorous in the plant material. (0.166) Whether by sheet flow or by traversing swales, overland flow would reach Gator Cove within hours. Effluent traveling through the surficial aquifer would not reach the lake for at least five years. (S.238-9). It could take as long as 45 years. (0.316). In the course of the effluent's subterranean passage, the soil would take up or adsorb phosphorous until its capacity to do so had been exhausted. In addition, interaction with certain chemicals found in the soil, primarily calcium, precipitates phosphorous dissolved in groundwater. As between adsorption and precipitation, the former is much more significant: "[W]ith a three-meter distance you can expect at least 70 to 80 percent removal of phosphorous just by a a[d] sorption alone." (0.21). Precipitated phosphorous does not return to solution, unless the soil chemistry changes. (0.19) Adsorption, however, is reversible, although not entirely, because of the "hysteresis phenomenon." (0.19) Eventually, a kind of dynamic equilibrium obtains to do with the binding of the phosphorous to soil constituents, binding or precipitation of phosphorous. At some point . all of the binding sites become saturated . [and] the amount of phosphorous leaving, into the lake really, will be equal to the amount of phosphorous going into the the system. When there is no more place to store the phosphorous in the ground, then the output is equal to the input and that is called the steady state. (0.161) Although precipitation of phosphorous would not reach steady state under "conditions that render the phosphorous-containing compound insolu[]ble," (0.168) these conditions were not shown to exist now "much less . . . on into perpetuity." Id. Spring Seep A third possible route by which the effluent might reach lake waters would begin with percolation through the sand, which is to be placed on grade and on top of which the percolation ponds are to be constructed. Underground, the effluent would move along the hydraulic gradient toward the lake unless an impeding geological formation (an aquiclude or aquitard) forced it above ground lakeward of the percolationi ponds. In this event, the effluent would emerge as a man-made spring and complete its trip to Gator Cove, or directly to the lake, overland. The evidence demonstrated that a spring seep of this kind was not unlikely. Relatively impermeable clayey soils occur in the vicinity. A more or less horizontal aquitard lies no deeper than four or five feet below the site proposed for the percolation ponds. Conditions short of an actual outcropping of clayey sand could cause effluent mounding underground to reach the surface. Nor did the evidence show that an actual intersection between horizontal aquitard and sloping ground surface was unlikely. Such a geological impediment in the effluent's path would almost surely give rise to a spring seep between the pond site and the lakes. In the case of the other percolation ponds in this part of the state that do not function properly, the problem is n [U] sually an impermeable layer much too close to the bottom of the pond," (S.179), according to Mr. Frey, manager of DER's Northeast District. Phosphorous in effluent travelling by such a mixed route would be subject to biological uptake as well as adsorption and precipitation, but again a "steady state" would eventually occur. On Dr. Bothcher's assumptions about the conductivity of the clayey sand (or sandy clay) lying underneath the topsoil, the effluent would accumulate as a mound of groundwater atop the clay unit, and seep to the surface in short order; and "after a matter of probably weeks and maybe months, it would be basically of the quality of the water inside of the percolation pond." (0.278). More Phosphorous in Gator Cove The total annual phosphorous load from all existing sources "to the lake" has been estimated at 2,942 kilograms. Assuming an average effluent flow of 17,000 gallons per day from the proposed plant, "the total phosphorous load [from the proposed plant] will be 235 kilograms per annum," (0.16), according to Dr. Pollman, called by SFP as an expert in aquatic chemistry. Even before any steady state condition was reached, 20.75 to 41.5 kilograms of phosphorous, or approximately one percent of the existing total, would reach the lake annually from the proposed plant, on the assumptions stated by Dr. Pollman at 0.22-23 (90 to 95 percent removal of phosphorous in the soils and average daily flow of 30,000 gallons). Santa Fe Lake is more than two miles across and two miles long, and Little Santa Fe Lake, which may be viewed as an arm of Santa Fe Lake, is itself sizeable, with a shoreline exceeding two miles. But Gator Cove is approximately 200 yards by 100 yards with an opening into Santa Fe Lake only some 50 to 75 yards wide. (0.154). On a site visit, Dr. Parks observed "luxuriant growth of submerged plants" (0.154), including hydrilla, in Gator Cove. If a one percent increase in phosphorous were diffused evenly throughout the more than eight square miles Santa Fe Lake covers, there is no reason to believe that it would effect measurable degradation of the quality of the water. Some nutrients are beneficial, and the purpose of classifying a lake is to maintain a healthy, well-balanced population of fish and wildlife. It's hard to see how 1.4 percent increase would lower the ambient quality. But . . . seepage into Gator Cove, which is a much more confined place [100 by 200 yardsj [would make it] quite probable that there would be a lowering of ambient water quality in the site . R] educed dispersion . . . in this cove would allow . . . phosphorous to build up. (0.156) Overland effluent flow to Gator Cove would increase concentrations of phosphorus there, with a consequent increase in the growth of aquatic plants, and the likely degradation of waters in the Cove, unless rapid and regular exchange of lake and cove waters dispersed the phosphorous widely, promptly upon its introduction Except for testimony that wind-driven waves sometimes stir up phosphorous laden sediments on the bottom, the record is silent on the movement of waters within and between Lake Santa Fe and Gator Cove. The record supports no inference that phosporous reaching Gator Cove would be dispersed without causing eutrophic conditions significantly degrading the water in the Cove. Neither does the record support the inference, however, that effluent moving underground into the lakes would enter Gator Cove. On this point, Dr. Bottcher testified: [T]he further away from the lake that you recharge water the further out under a lake that the water will be recharging into the lake; gives it a longer flow . . . it's going to migrate and come up somewhat out into the lake. (0.281-2) Phosphorous in the quantities the treatment plant would produce, if introduced "somewhat out into the lake" would probably not degrade water quality significantly, notwithstanding testimony to the contrary. (0.349, 354). Sands and Clays DER gave notice of its intent to deny SFP's original application because SFP proposed to place the pond bottoms approximately two and a half feet above an observed groundwater table. Placement in such proximity to groundwater raised questions about the capacity of the ground to accept the effluent. In its revised application, SFP proposes to place sand on the existing grade and construct percolation ponds on top of the sand. By elevating the pond bottoms, SFP would increase the distance between the observed groundwater table and pond bottoms to 5.2 feet. (S.256, 257). This perched water table, which is seasonal, is attributable to clayey sand or sandy clay underlying the site proposed for the percolation ponds. Between January 9, 1985, and January 17, 1985, "following a fairly dry antecedent period," (S.229) Douglas F. Smith, the professional consulting engineer SFP retained to prepare the engineering report submitted in support of SFP's permit applications, conducted six soil borings in the vicinity of the site proposed for the plant. One of the borings (TB 5) is in or on the edge of a proposed percolation pond and another (TB 4) is slightly to the north of the proposed pond site. Three (TB 1, 2 and 3) are east of the proposed pond site at distances ranging up to no more than 250 feet. The sixth is west of the proposed site in a natural depression. Mr. Smith conducted a seventh test boring under wetter conditions more than a year later a few feet north of TB 4. Finally, on September 5, 1986, during the interim between hearing days, Mr. Smith used a Shelby tube to obtain a soil sample four to six feet below grade midway between TB 4 and TB 5. 1/ The sites at which samples were taken are at ground elevations ranging from 173 to 178 feet above sea level. From the original borings and by resort to reference works, Mr. Smith reached certain general conclusions: The top four feet or so at the proposed pond site consists of silty sand, 17 percent silt and 83 percent quartz sand. This topsoil lies above a two-foot layer of clayey sand, 20 percent clay, 6 percent silt and 74 percent sand. Below the clayey sand lies a layer some eight feet thick of dense, silty sand, 23 percent silt, 7 percent clay and 70 percent sand, atop a one and one-half foot layer of clayey sand, separating loose, quartz sands going down 40 feet beneath the surface from what is above. These formations "are very heterogeneous, in the sense of the position and occurrence of the clay layers or the sandy layers . . .," (0.230) and all occur within the surficial aquifer. "There are layers of clay within it, and so perched water tables are rather common." (0.225). In March of 1986, the regional water table was some 17 feet down. SFP Exhibit 1B. Below the surficial aquifer lie the Hawthorne formation and, at a depth of 110 feet, the limestone of the Floridan aquifer. The soils above the Hawthorne formation are not consolidated. (S.254, 255). Conductivity Measurements The applicant offered no test results indicating the composition or conductivity of soils lying between the easternmost test boring and Gator Cove, some 1,200 feet distant. No tests were done to determine the conductivity of the deeper layer of clayey sand beneath the site proposed for the ponds. Tests of a sample of the topsoil in TB 7 indicated horizontal permeability of 38.7 feet per day and vertical permeability of six feet per day. On the basis of an earlier test of topsoil in TB 3, "hydraulic conductivity of the surface soils was measured to be 8.2 feet per day. . . ." SFP's Exhibit No. 1B. From this measurement, vertical hydraulic conductivity was conservatively estimated at .82 feet (9.84 inches) per day. Id. The design application rate, 2.41 inches per day, is approximately 25 percent of 9.84 inches per day. Id. The initial test done on a sample of the clayey sand, which lay beneath the topsoil at depths of 3.5 to 5.5 feet, indicated a permeability of 0.0001 feet per day. Thereafter, Mr. Smith did other testing and "made some general assumptions" (S. 235) and concluded that "an area-wide permeability of this clayey sand would be more on the order of 0.0144 feet per day." (S. 234). Still later a test of the sample taken during the hearing recess indicated hydraulic conductivity of 0.11 feet per day. SFP's Exhibit No. 10. The more than thousandfold increase in measured conductivity between the first laboratory analysis and the second is attributable in some degree to the different proportions of fines found in the two samples. The soil conductivity test results depend not only on the composition of the sample, but also on how wet the sample was before testing began. Vertical Conductivity Inferred On March 6, 1986, ground water was observed on the site about two and a half feet below the surface. SFP's expert, Mr. Smith, concluded that it was "essentially a 1.5 foot water table, perched water table over the clay." (0.422). There was, however, groundwater below, as well as above, the clay. On March 12, 1986, the water table at this point had fallen six inches. In the preceding month rainfall of 5.9 inches had been measured in the vicinity, after 5.1 inches had been measured in January of 1986, but in November and December of 1985 "there was a total of 0.6 inches of rainfall." (0.421). Later in the year, notwithstanding typically wet summer weather, no water table was measured at this point. From this Mr. Smith concluded that, once the clayey sand layer is wetted to the point of saturation, conductivity increases dramatically. If that were the case, a more or less steady stream of effluent could serve to keep the clayey sand wetted and percolation at design rates should not be a problem. But Dr. Bottcher, the hydrologist and soil physicist called as a witness for the Association, testified that the six- inch drop over six days could be attributed, in large part, to evapotranspiration. He rejected the hypothesis that the clayey sand's conductivity increased dramatically with saturation, since "the actual water table was observed . about three weeks after the very heavy rainfall had stopped" (0.290) and had probably been present for at least a month; and because the soil survey for Alachua County reports that perched water tables ordinarily persist for two months (0.227) in this type of soil. Certain soils' hydraulic conductivity does diminish with dessication, but such soils usually regain their accustomed conductivity within hours of rewetting. Dr. Bottcher rejected as unrealistically optimistic the assumption SFP's expert made about the conductivity of the clayey sand on grounds that "the conductivity that . . . [SFP] used, if you went out there you couldn't perch a water table for a month." (0.277). In these respects, Dr. Bottcher's testimony at hearing has been credited. In the opinion of the geologist who testified on behalf of the Association, Dr. Randazzo, a minimum of seven or eight additional augur borings in "definitive patterns to the northeast and to the northwest" (0.240) to depths of 15 to 20 feet, with measurements within each augur boring every two feet, are necessary to determine "how permeable the soils are and how fast the waters would move through them." (0.240). This testimony and the testimony of the soil physicist and others to the same general effect have been credited, and Mr. Smith's testimony that no further testing is indicated has been rejected. Wet Ground In the expert opinion of a geologist who testified at hearing, "it is reasonable to assume that saturation conditions of the surficial aquifer in this area can be achieved," (0.238) even without adding effluent from a wastewater treatment plant. The evidence that soils in the vicinity of the site have a limited capacity to percolate .water came not only from engineers and scientists. Charles S. Humphries, the owner of the property 150 feet from the proposed percolation site, "put a fence post line . . . every ten feet, and every ten feet [he] hit clay." (0.372). Three quarters of an inch of rain results in waters standing overnight in neighboring pastures. In parts of the same pastures, rain from a front moving through "will stay for a week or so." (0.373). It is apparent that the area cannot percolate all the rainfall it receives. This is the explanation for the gully leading down toward Gator Cove. Six-feet deep (0.377), "the gully is a result of natural surface runoff." (0.263).
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.

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.

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.

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 disputed issues are as follows: Whether the proposed Water Conservation Plan is sufficient to meet the requirements of the District rule; Whether the proposed pumping will adversely affect wetlands and wetland vegetation in contravention of District rule; Whether the permit applicant has provided reasonable assurance of entitlement to the requested permit as required by the District rule; and What limiting conditions pursuant to Rule 40C-2.381, F.A.C., should be imposed on the Consumptive Use Permit (CUP).
Findings Of Fact THE PARTIES The Commission was created by the legislature pursuant to Public Law 67-1754 in combination with Public Law 85-503. Its principal office is located in New Smyrna Beach, Volusia County, Florida. The Commission is charged with maintaining a water supply and providing wastewater treatment and electrical power. The District is an agency created pursuant to Chapter 373, Florida Statutes, in charge of regulating, among other things, consumptive uses of water in a 19 county area of the State of Florida, including all of Volusia County. The geographical boundaries of the District are described in Section 373.069(2)(c), Florida Statutes. Vernon and Irene Beckham are property owners of the property proposed for the construction of the new State Road 44 wellfield. Volusia City-County Water Supply Authority is a cooperative created by interlocal agreement in accordance with Section 163.01, Florida Statutes (1991), which party made no appearance at the Formal Administrative hearing but adopted the position of the Commission. Nassau is an individual residing at 4680 Cedar Road, New Smyrna Beach, Florida. THE APPLICATION The present service area of the Commission encompasses approximately 43 square miles, of which only about 15 square miles of the service area are located in the City of New Smyrna Beach. On August 8, 1984, the District issued Consumptive Use Permit No. 2- 127-0214NG to the Commission for its Glencoe and Samsula wellfields, which permit would expire in seven years. The combined authorized withdrawal of the existing wellfields is 5.2 mgd on an average day and 8.31 mgd on a maximum day. In December 1990, the Commission submitted its Consumptive Use Permit Application to renew the existing permit, including the development of an additional water supply wellfield. This application also sought an increased allocation to meet projected demand for the Commission's service area. The total allocation sought was 5.59 mgd on an average day and 8.31 mgd on a maximum day. However, the District has recommended 5.29 mgd on an average day and 7.62 mgd on a maximum day by 1998. The source of the water for all three wellfields is the Floridan aquifer. The Floridan aquifer can produce the volumes of water requested based on the past pumpage from the Samsula wellfield and the Glencoe wellfield. The Glencoe wellfield has been in operation since early 1950. The Samsula wellfield has been in operation since 1982. The Commission has never exceeded the currently permitted withdrawals as measured by annual, daily, or peak basis. WATER DEMAND Approximately 75% of the demand is related to residential consumption. Approximately 10% of the demand is related to commercial and industrial consumption. Approximately 7% of the demand is related to irrigation. Lastly, approximately 8% of the demand is for miscellaneous consumption, including loss that occurs in the treatment process itself. Gross water use in the area served by the Commission is about 138 gallons per person per day. The approximate 103 gallons per person per day (net) used by residences is small as compared to other providers of potable water. The present population of the Commission's service area is approximately 31,570 customers. The projected 1997 population of the Commission's service area is 40,680. The Commission's population projections were obtained by methods consistent with the District's Permit Manual. VI. PERMIT CRITERIA Water Conservation Plan The Commission has submitted a complete Water Conservation Plan. The implementation of that plan is a condition of the permit. The Water Conservation Plan includes a customer audit program of the system to determine how much water is pumped and where the water goes once it is distributed. The customer audit program involves employees of the Commission discussing the historical water usage with the customer, detection of leaks, installation of water restrictors, and the prevention of freezing pipes in the wintertime. The Commission encourages reduced consumption through the water meter charges. Larger meters use more water than smaller meters. The monthly charge for the larger meters is higher thereby encouraging the use of smaller meters. The Water Conservation Plan includes a pressure monitoring program to detect leaks in the system. The program has been implemented. The system pressure monitoring plan measures the pressure in different zones around the Commission's service area and, should a large main burst, an alarm is triggered. Repair of that water main would occur immediately. The Water Conservation Plan includes an analysis of the economic, environmental and technical feasibility of using reclaimed water in Commission's Exhibit No. 14, Reuse of Reclaimed Wastewater Conceptual Planning Document. The Reuse of Reclaimed Wastewater Conceptual Planning Document involves four major phases of construction starting in 1991 with completion in 1995. The first phase is underway. As part of the reuse plan, the Commission is modifying the wastewater treatment plant to accept reuse water. The construction is 99 percent complete. A total cost for that is approximately 1.5 million. The Commission will be replacing some freshwater irrigation sources with reclaimed water. The Commission has valid DER permits for this use of reclaimed water. As part of the reuse plan, the Commission has entered into construction contracts to serve the municipal golf course, the landscape at city hall and city parks with wastewater. The transmission and distribution lines will be completed before October 1992. The cost is approximately $700,000. Other phases of the reuse plan include construction of the major infrastructure inside and outside the city for reuse distribution. Total investment is in excess of five million dollars. Major customers along the route have been identified to increase the demand on the reuse system. The Water Conservation Plan includes an employee awareness program and an educational program as well as a time frame to implement those programs. The Commission has a public relations program to inform the customers about water conservation which includes newspaper publications concerning reading water meters, xeriscaping, and methods to reduce water consumption and the time/temperature machine which has prerecorded messages. The Commission has a program for educating the public and encouraging xeriscaping or the use of drought resistant foliage. Xeriscaping is implemented at the wastewater lift stations. The Commission has used direct mailing to provide water conservation information to customers. The Commission has a program for inspecting and replacing defective meters. If a meter malfunctions, the replacement reduces the system losses and accurately records water usage. The Commission has a program to monitor unmetered uses, which includes reporting from users such as the fire department of their unmetered use. On a monthly basis, the fire department reports its water usage as calculated by its operation schedule. The Commission is using the lowest acceptable quality water source, including reclaimed water, for certain types of needs such as irrigation of golf courses. The Water Conservation Plan addresses the use of treated effluent to minimize withdrawals of groundwater. Issues Related to Reasonable Assurance Hydrogeology The Floridan aquifer occurs at approximately 100 feet below the land surface throughout Volusia County. It's overlain by approximately 100 foot of sandy and clayey material collectively called the Clastic aquifer or the surficial aquifer. The proposed SR 44 wellfield site is underlain by an approximate 900- foot depth of freshwater of the Floridan aquifer. In the high recharge area of the Deland Ridge, water moves rapidly into the surficial aquifer and recharges the Floridan aquifer. A regional groundwater gradient extends from the Deland Ridge towards the east. There is a volume of water in the Floridan aquifer that is constantly moving from the west to the east to replenish water that is being withdrawn. Based on the regional movement of the Floridan aquifer and the nature of the Floridan aquifer, the water that is being replenished by the withdrawal is mainly coming from the Floridan aquifer with some contribution from the surficial. Another way to determine the source of the water is by geochemical analysis. The source of the water for this use is characterized as freshwater category number three meaning that it is Floridan aquifer water that is replenishing the water that is being withdrawn and not surface water that is going directly into the Floridan aquifer system. Aquifer Tests The aquifer performance test at the SR 44 wellfield shows that the aquifer is able to produce the volumes of water requested. The depths of the proposed wells, and APT test well, at the SR 44 wellfield is 250 feet below land surface or 150 feet into the Floridan aquifer. The APT at the SR 44 wellfield site provided for the collection of data to show what happens to the water levels while the aquifer is stressed. The second APT at the SR 44 wellfield site tested the Floridan aquifer at a depth of 750 feet below land surface. The section of the Floridan aquifer tested was 500 feet thick. The second APT and geophysical logs showed that there were not any additional flow zones below the upper Floridan aquifer which would yield additional water. Prior to the pump recovery test at the Samsula wellfield, the wells were pumping at 2.59 million gallons per day for a couple of days prior to shutting them off. For a period of five days, four wells in the vicinity of the Samsula wellfield were monitored by the District for water level recovery. The actual observations and the predicted drawdowns in the model correlated well. Drawdown does occur at homeowners' wells when the Commission's Samsula wellfield is pumping, but it does not interfere with existing legal users based on the District rules. The drawdown will not cause a ten percent reduction in the withdrawal capability of the homeowner's well. Computer Modeling The PLASM model simulates the response of the surficial and Floridan aquifers to pumping. The computer model oversimplifies the nature of the surficial aquifer by characterizing the layer as a solid homogeneous type of a system, basically being all sand. In reality, there are some shell and clay layers or hardpan. The transmissivity or the ability to transmit water through the aquifer for surficial aquifer sand ranges between 1,000 up to about 12,000. The transmissivity in the model is 5,000 gallons per day per foot (gpdpf) for Layer 1 which was reasonable. In Layer 2, the data from the APT produced a value of 50,000 gpdpf and a leakance value, or value that would correspond to water that moves from the surficial aquifer down to the Floridan aquifer, of 0.0012 gpdpf. This 50,000 and 0.0012 values are reasonable numbers for this area of Volusia County. The PLASM model is an accepted model for simulating pumpage. In the PLASM model, the transmissivity was varied in two different directions, but it averaged 50,000 gpdpf in the Floridan aquifer system. In the Floridan aquifer system, water is going to be moving based on the transmissivity of the aquifer and a leakance value from the surficial aquifer. The water primarily flows in a horizontal direction. There is a component of vertical movement. The difference between the horizontal movement and the vertical movement is an order of magnitude. There's an order of magnitude difference between the 50,000 gpdpf and the 0.0012 gpdpf which shows that the majority of the water is coming from a horizontal direction. There is some vertical movement. The vertical movement is not only from above, but because of the Floridan aquifer there is also vertical movement from below. When a well is pumping water, the water is being replenished mostly from the horizontal direction and from the lower direction in the same aquifer system, with some contribution downward based on the leakance value from above. This is demonstrated or shown by a small predicted drawdown in the surficial aquifer and that predicted drawdown is basically two orders of magnitude less than the drawdowns in the Floridan aquifer. Proposed Recommended Withdrawal Rates The proposed recommended withdrawal rate from the SR 44 wellfield is 1.43 mgd for average daily flow. With the proposed recommended withdrawal of 1.43 mgd at the SR 44 wellfield, the maximum drawdown in the surficial aquifer is approximately 0.34 feet. With the proposed recommended withdrawal of 1.43 mgd at the SR 44 wellfield, the maximum drawdown in the Floridan aquifer is approximately ten feet. A withdrawal of 1.93 mgd at the SR 44 wellfield site would result in a maximum drawdown in the surficial aquifer of 0.7 feet and in the Floridan aquifer of thirteen (13) feet. The proposed recommended withdrawal rate from the Samsula wellfield is 1.93 mgd for average daily flow. With the proposed recommended withdrawal of 1.93 mgd at the Samsula wellfield, the maximum drawdown in the surficial aquifer is approximately seven tenths (0.70) of a foot. With the proposed recommended withdrawal of 1.93 mgd at the Samsula wellfield, the maximum drawdown in the Floridan aquifer is approximately seventeen (17) feet. The proposed recommended withdrawal rate from the Glencoe wellfield is 1.93 mgd for average daily flow. Under the existing permit, the Samsula wellfield is withdrawing at the higher rate of approximately 2.59 million gallons per day. The volumes of water requested from both the Samsula wellfield and the SR 44 wellfield have been reduced from what was originally proposed by the Commission. The reduced allocation for the Samsula wellfield will improve groundwater elevations and thereby reduce groundwater impacts. Water Quality The state water quality standard for public drinking water is 250 milligrams per liter (mg/l) chlorides. For water supply systems where the chloride level is below 250 mg/l, the District uses that level to determine whether or not the pumping is going to cause significant saline water intrusion. The proposed use cannot cause the water quality to exceed 250 mg/l in chlorides. The water quality data from the existing Samsula and Glencoe wellfields shows that none of the wells or trends from the indicate that they are either above 250 mg/l or trending in a degradation mode toward 250 mg/l. The water quality in the wells is stable without degradation of the water quality in either of the Glencoe wellfield or the Samsula wellfield. The water quality data collected during the APT at the SR 44 wellfield showed that the chlorides were below 250 mg/l and that during the test, there was no change or a trend of becoming salty. An independent study used geophysical methods to determine the depths below land surface where high concentrations of saline water exist. That depth was at approximately 1200 feet below land surface. Proposed Permit Conditions The Commission accepts the conditions of the permit as proposed in the Commission Ex. 10-B. The proposed conditions require the Commission to limit the withdrawals per wellfield as specified and to monitor each production well with a flow meter, monitor the groundwater levels, monitor the surface water conditions, monitor rainfall, and monitor the wetlands. The proposed permit conditions and the County's ombudsman program adequately address the possible impacts of the proposed wellfield on existing users. The monitoring will be able determine the impact of the wellfield on those users. The Commission accepts the condition to mitigate for interference with existing legal users in compliance with the proposed permit conditions. The Volusia County ombudsman program provides the method of investigating and resolving issues related to interference of the proposed wellfield operation with existing legal users. The Commission will participate in this program. The Commission's purchase of the property is contingent upon obtaining the consumptive use permit. The Commission will own the site as shown on various exhibits. The drainage pattern of Tiger Bay is northerly for most of the basin. A canal located north of the area provides the primary drainage for Tiger Bay. A small drainage area within Tiger Bay of approximately 90 acres drains south into the SR 44 wellfield site. Some of the drainage does come through the two 30-inch culverts under SR 44, and both commingle with the wetlands that are on the site as well as drain into a ditch located along the Ranchette Road. The maximum capacity at ideal conditions for those two culverts would be approximately 300 CFS, cubic feet per second. The entire Tiger Bay drainage basin is approximately 13,000 acres. The volume of surface water which can flow from Tiger Bay is 13,000 cfs. That volume could not flow through the culverts at SR 44 without overtopping the road. Ecology The upland communities surrounding the Samsula wellfield are primarily pine flatwoods and mixed pine forested areas. The proposed 1.93 mgd average day withdrawal quantity being recommended by the District for the Samsula wellfield will not adversely affect these upland communities because: (a) the upland communities do not rely on inundated or saturated conditions so the proposed consumptive use will not adversely affect the hydrology these upland communities rely on; and (b) the magnitude of the predicted drawdown will not cause a shift in vegetation meaning a change in the types of plants that already exist there. The wetland communities surrounding the Samsula wellfield site consist of cypress dome and bay swamp communities. With the projected drawdowns information for the Samsula wellfield, there will not be significant adverse impacts to uplands or wetlands that would be identifiable based upon the projected wellfield withdrawal rates as recommended by the District. Any potential for impacts has been reduced in that the current pumpage rates are projected to decrease. The proposed 1.93 mgd average day withdrawal quantity being recommended by the District for the Samsula wellfield will not cause the water table to be lowered such that these wetland communities will be significantly and adversely affected for the following reasons: The wetlands in the area of the Samsula wellfield lie in a sloped terrain. Underlying the site is a soil area known as a spodic horizon or a hardpan layer. The spodic horizon is an area where there is a deposition of organics and it has a different chemistry than the surrounding soils. The spodic horizon, when saturated, acts as a semi-impervious or impermeable layer which causes impedance of water as it goes through. This spodic horizon in the area of the Samsula wellfield is typically two feet below the soil surface. The predicted drawdown will not cause water levels to be dropped such that in normal wet season conditions, which is the time when hydrology to a wetland is most important, the spodic horizon will still be saturated so that water is coming into the wetlands through rainfall directly, as well as rainfall that falls on the adjacent uplands and moves laterally through the soils to the wetland above the spodic horizon. Thus, the spodic horizon will prevent a shift in the "water budget" of these wetlands such that the wetlands will not be harmed by the proposed use. The wetlands systems surrounding the Samsula wellfield are primarily densely forested systems with a fairly substantial accumulation of organic or muck type soils in the surface. The soils assist these wetlands in retaining moisture which provides a "built-in system" for the wetlands to withstand fluctuations in hydroperiods. The wetland systems surrounding the Samsula wellfield appear to have an altered hydrology. The identifiable impacts are ditches or shallow swales along State Road 44. The wetlands south of 44 in the vicinity of wells one, two and three have been bisected by roads and there are swales cut adjacent to those roads. The power line that runs north-south has cut off and eliminated half of a cypress wetland south of 44 and about half of a cypress wetland north of 44. It is possible that these ditches and roads may have caused the altered hydrology in these wetlands. It cannot be concluded that the current Samsula wellfield operation has caused this altered hydroperiod. However, the drawdown that is predicted to occur at the Samsula wellfield under the proposed 1.93 mgd average day withdrawal being recommended by the District is much less than the drawdown that is occurring from the current pumpage at this wellfield. The projected drawdowns from the proposed three wellfield configurations indicate less potential for impacts than the current two wellfields as far as Samsula is concerned. Thus, even if the wetlands surrounding the Samsula wellfield have been affected in any way by the current pumpage rate, the reduced drawdown rates that will result from the 1.93 mgd average day proposed pumpage rate will greatly improve this condition. Other than slight alteration along the edge of SR 44, the wetlands in the vicinity of Samsula wells five and six have not been significantly altered. No changes in vegetation and no apparent changes in hydrology occur in those areas. The cypress wetland north of SR 44 has a drainage ditch emerging to the east. Another wetland immediately north of SR 44, north of well four, is adjacent to the road and the roadside swale or ditch in that vicinity. The species of wildlife identified are ones that are adapted to altered conditions. Abundant wildlife is generally found living in association with improved pastures and close proximity to man. Most of the wetlands in the area of the Samsula wellfield, north and south of SR 44, are in improved pasture or where roads and power lines have been cut. There was evidence of impacts to the wetlands and some drainage. The edge of the cypress dome north of SR 44 has blackberries and other weedy type species along the margins of it. The wetland immediately southeast of well one at the Samsula wellfield was a healthy bay dominated area with ferns underneath. The lichen line on the trunk of the tree and the mosses indicate that the water has been up to or near the historical high within the past season or two. Otherwise, the lichens would grow at the base of the tree. At the Samsula wellfield site, there are no wetlands within the inner drawdown contour of 0.7. There are some wetlands between the 0.7 and the 0.5 contours. The upland communities in the vicinity of the proposed SR 44 wellfield are primarily pine flatwoods and improved pasture. In the pine flatwoods areas, the soils indicate that the water table extends from a height of 0.5 feet below land surface and down to a hardpan layer. The water table in the pine flatwoods fluctuates between the hardpan and 0.5 feet below land surface. The proposed 1.43 mgd average daily withdrawal which is being recommended by the District for the proposed SR 44 wellfield will not significantly and adversely affect these upland communities because these upland communities are not reliant on inundated or saturated conditions, and the proposed consumptive use will not cause a shift in hydrology such that the vegetation found in these communities will no longer be there. The wetland communities in the vicinity of the proposed SR 44 wellfield consist of cypress sloughs and cypress domes which also have herbaceous areas with them. The cypress dominated wetlands are on the northeastern portion of the site and the northwestern portion of the site extending down through the central and southeastern part of the site. Cypress dominated wetlands occur on the southwestern border with one in the east-central portion of the site. Between the cypress dominated wetlands and pine flatwoods are grass prairies. The Commission determined the hydroperiod of the wetlands using vegetative physical evidence or biological indicators, such as lichen lines and mosses, and soil physical evidence from soil probes, which are indicators of long-term and sometimes short-term changes. The wetland on the east-central portion of the proposed SR 44 wellfield site inundates to approximately six and one half inches. In the dry season, the soils dry out to 0.15 feet below land surface. In the wet prairie or wet grassy area, the water table seasonally fluctuates between the hardpan layer of 2.2 feet bls and a tenth or two-tenths of an inch above the surface as based on adventitious roots growing from a St. Johns wort plant species. The water table fluctuations explain the seasonal high and the seasonal low water elevations. The factors which most influence the wetlands and their hydrology are subsurface flow during the wet season, the runoff and direct rainfall. The proposed 1.43 mgd average daily withdrawal for the proposed SR 44 wellfield will not significantly and adversely affect these wetland communities because these wetlands are also underlain by a spodic horizon which, as in the case of the Samsula wellfield wetlands, functions to provide lateral movement of water into the wetlands. The predicted drawdowns for the proposed SR 44 wellfield will not lower the water levels in these wetlands so as to prevent the spodic horizon from performing this function. The recommended withdrawal rate of 1.43 mgd for the proposed SR 44 wellfield reduces the opportunity for impacts. The part of the wellfield site where the greatest drawdown of 0.34 feet occurs is the furthest away from the majority of the wetlands on the site. However, the wetland and soil types on the surface layer are different than the wetland and soil types found at the Samsula wellfield site. The District is recommending a pumpage rate for the proposed SR 44 wellfield that would result in a maximum .34 feet of drawdown in the surficial aquifer while recommending a pumpage rate that would result in a maximum .7 foot drawdown in the surficial aquifer for the Samsula wellfield. The wetlands at the proposed SR 44 wellfield site do not have the dense canopy as well as the accumulation of muck soils in the surface that the wetlands at the Samsula site have. Additionally, the wetlands in the vicinity of the proposed SR 44 wellfield site include herbaceous systems which tend to be shallower systems, not as deeply set as the forested cypress systems are, and therefore tend to be more sensitive to changes that occur in the top couple of inches of soil which is above the spodic horizon. Thus, the wetlands in the vicinity of the proposed SR 44 wellfield would be significantly and adversely affected if the Commission were permitted to withdraw water at a pumpage rate that would result in a drawdown of greater that .34 feet. The drawdowns upon which the evaluation of potential wetland impacts are based are predicted drawdowns. Monitoring and Proposed Conditions To provide additional assurance, the District has recommended a series of permit conditions, numbered 31 through 45 on the Commission Ex. 10-B, that will require the permittee to conduct extensive groundwater and surface water monitoring, as well as vegetative monitoring in the vicinity of the proposed SR 44 wellfield and the Samsula wellfield site. Condition number 31 identifies the overall program of wetland and ground and surface water monitoring. Condition number 32 requires the permittee to install surficial aquifer monitoring wells in the vicinity of the wellfield sites. These monitoring wells will be constructed below the spodic horizon and inside and outside the "area of concern" which is the area within the tenth of a foot drawdown contour at the wellfield sites. This condition will enable the District to analyze how the proposed use is affecting the overall groundwater levels unaffected by the spodic horizon. Placing these wells both inside and outside the area of concern will allow the District to determine if any change in groundwater levels is due to the wellfields or normal climatic patterns. Condition number 33 will allow the District to obtain a constant record of information to analyze what trends are occurring in the wetlands in the wellfields and to have sufficient data during normal climatic variations of the wet and the dry seasons to determine the presence of a trend. The required period of record collection, defined in this condition as the shorter of one calendar year or one consecutive wet to dry season, is a sufficient period of record collection because the purpose of this condition is to obtain a picture in time of the existing conditions in the wetlands surrounding the wellfields during the dry season and the wet season. Condition 33 requires the permittee to submit an annual hydrologic report to the District. This is a sufficient time period of reporting because the purpose of the report is to allow the District to accumulate and assess an entire year's of data or the entire dry to wet season variation. With the annual report, any adverse wetland vegetation changes can be detected prior to any permanent harm to the wetlands. Condition number 34 requires the permittee to install shallow piezometers and staff gauges in the monitored and referenced wetland areas. The monitored wetlands are the wetlands inside the "area of concern." The referenced wetlands are outside the "area of concern." Condition number 34 will allow the District to analyze the hydrology above the spodic horizon. This in turn will allow the District to evaluate the hydrology of the monitored wetlands against the hydrology of the referenced wetlands to determine if any adverse impacts are occurring in the wetlands due to the wellfields' operation. Condition Number 35 requires the permittee to submit surveyed cross- sections of each of the monitored wetlands and the referenced wetlands. This condition will allow the District to receive a linear view of both the monitored and referenced wetlands so that when the District receives the groundwater and surface water information required by condition number 34, it can assign that information to a picture, and know what the wetlands look like under varying water conditions. Condition number 36 requires the permittee to select referenced wetlands similar to the wetlands that are going to be monitored in the area of concern. This will ensure that the reference wetlands match vegetatively and hydrologically with the wetlands that are being monitored within the area of concern. Condition number 37 requires the permittee to install rain gauges at both wellfield sites. This will allow the District to compare rainfall to groundwater information and determine what the relationship is between water levels in the surficial aquifer and the amount of rainfall that has occurred. Condition number 38 requires the permittee to monitor, on a weekly interval, the water levels in each of the monitored wetlands and in the referenced wetlands and submit annual reports of this data. Condition number 39 requires the permittee to install continuous recorders on the staff gauges and piezometers in the reference and monitored wetlands. The information gathered will provide the District with detailed records of the water fluctuations in these wetlands systems relative to rainfall input. Condition number 39 requires the permittee to submit annual reports of the information gathered to the District. The annual report will allow the District to determine if any adverse trends are occurring in the wetlands. No permanent adverse change could occur to the wetlands communities surrounding either wellfield before the District receives this annual report. Condition number 40 requires the permittee to conduct baseline water quality monitoring at each of the monitored wetlands. If any adverse change does occur to the wetlands surrounding either wellfield, and if the permittee chooses to mitigate for this adverse change by augmenting the wetland systems, then this permit condition will allow the District to ensure that the water used to augment those wetlands is of the same quality as the water currently found in those wetlands. Condition number 41 requires the permittee to initiate a baseline vegetative monitoring program of the monitored and reference wetlands at both wellfields. This condition will allow the District to have a vegetative picture of the wetlands prior to any pumpage. Condition number 42 requires the permittee to conduct a vegetative monitoring program of the monitored and reference wetlands at both wellfields with the initiation of withdrawals. Condition number 43 requires the permittee to provide a wetland similarity assessment for both wellfields. The permittee must compare the results of the wetland vegetative monitoring program each year against the baseline vegetative monitoring of the same wetland and against the vegetative monitoring of the referenced wetlands. This condition will assist the District in determining if any adverse trends are occurring in the wetlands surrounding either wellfield. Condition number 44 requires the permittee to create two duplicate reference herbarium collections of the flora present in the monitored and referenced wetlands and the adjacent upland areas. This condition will ensure that there is consistency in the vegetative identification throughout the monitoring program. Condition number 45 requires the permittee to mitigate any harm to the wetlands that is detected from the monitoring required by other permit conditions. This condition does not require any particular form of mitigation. The wellfield withdrawals at the projected rates and the suggested permit rates should not have an impact on threatened or endangered plant or animal species in the Samsula wellfield area or the proposed SR 44 wellfield area. The monitoring program will provide the data to determine on a short- term or long-term basis whether the pumpage rates are causing impacts. Potential harm can be mitigated by adjusting the quantities and locations of withdrawal. V. ATTORNEY'S FEES AND COSTS The Commission seeks fees and costs from Petitioner pursuant to Section 120.59(6), Florida Statutes (1991). Such entitlement requires a showing that the Petitioner brought this case or filed a pleading for an improper purpose. While the evidence does show that certain pleadings filed by Petitioner (or his attorney who withdrew 24 hours prior to the beginning of the hearing) may have had as one purpose the delay of the hearing scheduled for March 24, 1992, the totality of the evidence establishes that Petitioner's purposes were not improper. Section 403.412(5), Florida Statutes (1991), establishes the right of any citizen of the state to intervene into "proceedings for the protection of air, water, or other natural resources of the state from pollution, impairment, or destruction " The actions of Petitioner in this proceeding were not clearly shown to be for delay, harassment or other improper purpose. In fact, Petitioner handled himself well as a pro se litigant after his attorney's untimely withdrawal. If anyone acted with an improper purpose in this proceeding, it was Peter Belmont, Nassau's attorney until he withdrew less than 24 hours prior to the hearing. The record shows that Belmont entered into the representation of Nassau with full knowledge that he would seek all possible delays in the proceedings. He engaged in no preparation for the hearing and he left Nassau unprepared also. Belmont's bad faith actions in this case however can only be determined and remediated by the Florida Bar, not by the undersigned through an award of fees and costs. Finally, there has been no delay in these proceedings. The petition was filed with DOAH on January 16, 1992. The District moved to consolidate it with two other pending case set for January 20, 1992. Those cases were voluntarily dismissed. An Initial Order was sent to the parties on January 21, 1992, seeking suggested dates for the hearing. The hearing was set to begin March 16, 1992, less than 60 days from the filing of the case. A one week continuance was granted and the case was heard beginning on March 24, 1992. If anything, this case has proceeded expeditiously.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is recommended that the St. Johns River Water Management District enter a Final Order GRANTING the Utilities Commission of New Smyrna Beach's Consumptive Use Permit, subject to the March 9, 1992 permit conditions proposed by the District (Commission's Exhibit 10-B). RECOMMENDED this 13th day of May, 1992, in Tallahassee, Florida. DIANE K.

The Issue The issues are whether Respondent, Mosaic Fertilizer, LLC (Mosaic), has provided reasonable assurances that the proposed mining and reclamation of the South Fort Meade Mine in Hardee County can be conducted in a manner that comports with the applicable statutes and rules such that the proposed Environmental Resource Permit (ERP), Conceptual Reclamation Plan (CRP), variance from minimum standards for dissolved oxygen, and variance from littoral zone percentage provisions for the Project should be issued by Respondent, Department of Environmental Protection (Department).
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: Mosaic is a limited liability company authorized to do business in the State of Florida and is the applicant in these proceedings. It was formed by the merger of IMC Phosphates Company and Cargill, Inc., in 2004. Mosaic has applied for permits to mine, reclaim, and conduct associated activities on property in Hardee County, Florida, known as the South Fort Meade Hardee County tract. These activities are referred to in this Recommended Order as the "Project" or "site." The Department is a state agency with jurisdiction over ERP permitting under Part IV, Chapter 373, Florida Statutes, for phosphate mining activities with jurisdiction over phosphate mining reclamation under Part III, Chapter 378, Florida Statutes, and with jurisdiction over variances associated with phosphate mining under Section 403.201, Florida Statutes. Pursuant to that authority, the Department reviewed the ERP, CRP, DO Variance, and Zone Variance applications for the Project. Lee and Sarasota Counties are political subdivisions of the State of Florida. Both Counties have filed challenges to other mining applications and have been found to have standing in those cases. The site is located within the Greater Charlotte Harbor Basin, approximately sixty percent of which lies within Lee County. In this case, Lee County is concerned about the potential destruction of stream and wetlands in the mine area and the impact of mining and its effects on Charlotte Harbor and the Peace River. Sarasota County is a member of the Peace River Manasota Regional Water Supply Authority, and they jointly hold a water use permit, which authorizes them to withdraw water from the Peace River for potable supply. Sarasota County operates a water treatment plant on the Peace River downstream from the site and is concerned with potential impacts to water quality and wetlands. After three years of data collection and site analysis, on October 13, 2006, Mosaic filed applications with the Department's Bureau of Mine Reclamation for an ERP/Water Qualify Certification for the disturbance of approximately 7,756 acres of uplands, wetlands, and other surface waters within a 10,856– acre area which makes up the site; a CRP for the same parcel; and the associated Zone and DO Variances. Three sets of additional information were requested by the Department, and on January 31, 2008, the applications were deemed to be complete. On June 30, 2008, the Department issued Notices of Intent to issue the permits and grant the variances. The Project is located within the Peace River Basin. Little Charlie Creek, a tributary to the Peace River, enters the site in the northeast part of the tract and flows diagonally across the tract in a general southwest direction. The Project is located to the east of the Peace River, east of the town of Bowling Green, northeast of the City of Wauchula, and just south of the Polk-Hardee County Line in Hardee County, Florida. The Project site is twenty-nine miles from the Sarasota County line and fifty-three miles from the Lee County line. The Peace River eventually empties into Charlotte Harbor near Port Charlotte in Charlotte County. The Project consists of approximately eighty percent of upland land cover types, including large acreages converted to agricultural uses, such as cattle grazing, citrus production, and row crop production. The Project site consists primarily of citrus groves and pasture. Richard W. Cantrell, Deputy Director of Water Resources for the Department, has extensive experience and knowledge concerning agricultural parcels of this size in Central Florida. Based on his familiarity with the site, he indicated that all the streams have been impacted, the impacts to some areas of the site are severe, and the "site contains some of the most polluted streams with respect to sedimentation that I have ever seen." The other Mosaic and Department ecological experts familiar with the site concurred in that assessment, and the substantial data collections and application information support that assessment of the site. Of the 2,590.7 acres of wetlands on the property, approximately 751 acres of wetlands and other surface waters will be impacted. Of that 751, 91 are upland cut ditches or cattle ponds, 108 acres are other surface waters, and 274 acres are herbaceous wetlands. Virtually all of the native upland vegetation on the site has been destroyed due to the agricultural activities that have been undertaken on the site over time. Only remnant patches of native upland remain on the site. These comprise approximately nine percent of the site and are predominantly within the riparian corridors of Little Charlie Creek and the Peace River and are proposed to be preserved. The evidence established that the majority of the wetlands and streams proposed for impact are lower in quality; the higher quality wetlands are typically associated with the riparian stream corridors and are proposed to be preserved. The preserved uplands are primarily pasture but also include one hundred thirty-nine acres of upland forest. Twenty-nine distinct vegetative communities were mapped on the site during approximately two years of evaluation and assessment utilizing the Florida Land Use, Cover and Classification System (FLUCCS). There are numerous natural stream segments that were mapped on the parcel including the primary drainage systems on site, consisting of the Peace River, Little Charlie Creek, Lake Dale Branch, Parker Branch, and Max Branch. Substantial portions of the natural streams and their flood plains will be preserved; sixty-two natural stream segments totaling 58,769 linear feet will be mined. No sovereign submerged lands are proposed to be impacted by the activities. The Peace River to its ordinary high water line is sovereign submerged lands; however, no other streams on site are claimed as sovereign. Therefore, no authorization to utilize or impact sovereign submerged lands is required. The field work assessing the ecological condition of the site's wetlands, streams, and surface waters consisted of detailed quantitative and qualitative assessments using FLUCCS, the Wetland Rapid Assessment Procedure, and the Uniform Mitigation Assessment Methodology (UMAM) codified in Florida Administrative Code Rule Chapter 62-345. The level of assessment expended in evaluating the native upland and wetland habitats on the site was considerable and provided reasonable assurances that the current condition and relative value of the systems were adequately considered in the permitting process. From 2002 to 2004, Mosaic conducted intense ecological evaluations of the site, evaluating historical and aerial photography and other site documentation and conducting extensive examinations in the field, including vegetative, macroinvertebrate, and fish sampling and surveying, surface and ground water quality and quantity monitoring, wildlife observations, surveys and trapping, stream mapping and evaluation, soil analysis, and other efforts, both in areas to be mined and areas to be preserved, and in both uplands and in wetlands. The ecological assessments were primarily conducted prior to the hurricane events of 2004, although additional field work was conducted following the hurricanes. Mosaic and the Department's experts revisited the site in the fall of 2008 and agreed that the various ecological and biological assessments conducted prior to the hurricanes would tend to overstate the quality of the site as compared to its current condition. The hurricanes caused a significant amount of damage to the remaining forested habitats on the site. A formal wetland jurisdictional determination was issued and published without challenge in 2007 and therefore conclusively establishes the boundaries of the wetlands and surface waters on the site for permitting purposes. Seasonal surveys for wildlife on the site were conducted in 2003-2004 using the wildlife survey methodology prescribed and approved by the Florida Fish and Wildlife Conservation Commission. Specialized wildlife surveys and night-time surveys were also conducted. A total of 4,600 man hours of effort were expended to evaluate the presence of fish and wildlife, including threatened and endangered species, on the site. The entire site was surveyed, with over 2,600 miles of wildlife transects, to assess the presence of wildlife, and detailed information was recorded for all wildlife observations, including anecdotal observations by the ecologists performing the wetland assessments. Mosaic also engaged in an extensive effort to identify the natural stream channels proposed for impacts on the site. After discussion with the Department staff, Mosaic distinguished the natural streams in accordance with FLUCCS codes 511, 512, 513, and 514, as required by Florida Administrative Code Rule 62C-16.0051(4). Streams are a subset of the term "other surface waters" for ERP purposes. Although streams are defined in Section 373.019(18), Florida Statutes, as are other watercourses and surface waters, there is no operative use of, or reference to, streams in Part IV, Chapter 373, Florida Statutes, governing ERP permits. Also, there are no specific ERP mitigation requirements applicable to streams. Thus, the only specific regulatory use of the word "stream" occurs in the context of Florida Administrative Code Rule 62C-16.0051, and not the ERP rules. The Department and Mosaic established that the delineation of streams proposed for impact by mining on the site was sufficient and adequate for purposes of the CRP rules. In addition, Mr. Cantrell stated that, for purposes of the acre- for-acre, type-for-type (for wetlands) and linear foot (for streams) reclamation requirements in Florida Administrative Code Rule 62C-16.0051, the Department required Mosaic to delineate a stream as such until the point it enters or after it leaves a wetland area and to delineate the wetland polygon itself as a wetland, not a stream. This is true even if water continues to flow through the wetlands and reform as a stream at the other side. If the stream will not be impacted, then nothing in either the ERP or CRP rules requires its precise delineation, because the CRP rules apply only to reclamation of impacted areas. Thus, Lee County's assertion that "streams" has some special status by virtue of the definition in Section 373.019(18), Florida Statutes, has not been accepted. Mr. Cantrell further testified that the Department utilizes a substantially similar definition to delineate "streams" pursuant to Florida Administrative Code Rule 62C-16.0051(4), but as noted in Findings of Fact 44-46, subsection (5) of the rule requires restoration on a linear foot basis only of natural streams. Lee County contended that over 12,000 feet of natural streams were omitted or misidentified in the application. However, based upon the evidence presented, both historical and current, and applying the applicable regulations and statutes, this argument has been rejected. This contention was based on after-the-fact approximation of stream locations and lengths plotted from memory in a desktop analysis. Further, during his site visit to mark stream locations, Lee County's expert failed to use a handheld GPS device or maps. Therefore, the evidence submitted by Mosaic and the Department as to the location and length of the streams proposed for impact has been credited. Mr. Cantrell testified that even the best of the streams proposed for impact have been subjected to at least sixty years of agricultural disturbance and manipulation. For example, the system 22 series of stream segments will be impacted and replaced by the clay settling areas. While the witness characterized segment 22(o) as the most stable and least impacted of the streams to be mined, that segment is 376 feet long and located at the uppermost reach of the 22 systems. It is an extremely small percentage of the overall 12,000 plus feet of less stable and more severely impacted parts of system 22. Mosaic and the Department analyzed the origins and current condition of the streams to be impacted, most of which are less than three-to-four feet wide and one foot or less deep and flow only intermittently and seasonally. The ecological and hydrologic conditions of the site and its fish and wildlife populations and habitat values were assessed for purposes of the ERP and CRP regulatory criteria. Respondents' characterization of the functional value of the wetlands, streams, and surface waters is supported by a preponderance of the evidence. Lee and Sarasota Counties' assertion that the site wetlands and streams are in "good" condition and can be easily restored is not credited in light of the lack of empirical data to support this contention. The only way to recover the phosphate ore is through mining to remove the overburden layer and expose the phosphate matrix with a dragline. The first step prior to any land disturbance associated with phosphate mining is the installation of a "ditch and berm" system, which is recognized as a best management practice (BMP) by the Department and the United States Environmental Protection Agency. Installation of the ditch and berm system proceeds in phases to protect unmined wetlands and habitats from mining impacts as mining progresses; it is not constructed all at once. The ditch and berm remains in place around an individual mining unit until mining and reclamation have been completed and monitoring indicates the revegetation is sufficiently established such that no violations of water quality standards will occur upon re-connection to adjacent and downstream waters. It is then removed in accordance with the reclamation plan. The system serves a number of purposes described below. Berms are required to be constructed in accordance with specific design criteria. The height of the berm will be designed in accordance with rules specific to such structures to prevent water from overtopping the berm during a 25-year, 24- hour storm event, even if the ditch becomes blocked. Following installation of a ditch and berm system, bulldozers clear the mining area of vegetation. Up to three large electrically powered draglines operate generally in parallel rows to remove the overburden layer (the upper layer of sand and clay soil), which is approximately 23.6 feet thick on average, to expose the phosphate matrix, which is approximately 13-to-15 feet thick on average. The overburden is cast to the side in piles to be later reused in reclamation. The phosphate matrix is a mixture of sand, clay, and phosphate, which must be separated after mining. At the beneficiation plant, washing, screening, and flotation processes are used to separate the phosphate rock from the sand and clay. After washing and screening, the sand is pumped back to the mine cuts for use in reclamation, and the clay is pumped to clay settling areas (CSAs) in slurry form to decant. Both the transport of sand back to the mine areas for use in reclamation and the transport of clays to CSAs are considered "mining operations," not "reclamation." See Peace River/Manasota Regional Water Supply Authority, et al. v. IMC Phosphates Company, et al., DOAH Case No. 03-0791 (DOAH June 16, 2006; DEP July 31, 2006); Fla. Admin. Code R. 62C-16.0021(10) and (15). Thus, contrary to Lee County's allegation, the transportation of clays and sand is not a valid consideration in the financial responsibility required for mitigation. Through testimony and its materials balance tables, which are part of the application, Mosaic demonstrated that it has sufficient sand tailings and other waste materials to meet all of its reclamation requirements mine-wide, including both the Polk side and the Project site. However, while there is sufficient sand available to create the proposed reclamation topography and contours, the tables and testimony demonstrated a need, on a mine-wide basis, for lakes, as voids will remain otherwise. There will be only a very small pile of available sand remaining after all reclamation obligations on both the Polk side and the Project are met, an insufficient amount to eliminate the need for deep lakes as proposed. Mr. Myers, Mosaic's Vice-President of Mining, testified as to the three basic ways the waste materials generated by the beneficiation plant are disposed of on-site to facilitate reclamation. Sand tailings will be utilized in areas to be reclaimed as native habitats, wetlands, and streams. Clays will be disposed of in CSAs. However, based on the materials balance and logistical issues, the "land and lakes" reclamation method, which utilizes only the available overburden material remaining on-site after mining, will be used for the lake reclamation. This method allows sand tailings preferential use in reclamation of native habitats and use of shaped and contoured overburden in areas not proposed for wetland mitigation. Such is the case for the proposed reclaimed lakes. A CSA is an above-grade impoundment to hold clay slurry pumped from the beneficiation plant. This clay slurry is pumped into one side of a CSA in the form of muddy water. The clay settles to the bottom, and the clear water remains at the top. The clear water is drawn out from the opposite side of the impoundment, where it is recycled back to the beneficiation plant and mine for reuse. Over time, the clay consolidates and solidifies to form a solid soil, the surface area is drained, and the impoundment reclaimed. Three CSAs will be constructed on the northern portion of the site to hold the clay that cannot be stored in already- permitted CSAs in Polk County. The use of stage filling has allowed Mosaic to have additional usable space in its CSAs, minimizing the footprint of new CSAs in Hardee County. In addition, approximately fifty percent of the clay waste from the site will be disposed of at the Polk site to further minimize the clay disposal footprint and eliminate and reduce impacts. To evaluate the number of CSAs required, Mosaic asked Ardaman & Associates, a consulting firm, to examine different clay generation scenarios when predicting the CSAs required by mining and beneficiation. The life of mine waste disposal plan, most recently updated in September 2008, indicated that, in all but one scenario (the seventy percent clay containment scenario), all three CSAs would be required. However, Mosaic witness Garlanger established that all three CSAs in Hardee County would be necessary based on the best available information as to the amount of clays reasonably likely to be generated by mining; the seventy percent scenario is not likely. No evidence was presented to rebut that testimony. A diversion system was also voluntarily included for the CSAs by Mosaic. In the highly unlikely event of a dam failure, this system will re- direct any escaped water and/or clay materials to adjacent open mining cuts where they can be safely stored. The diversion system will be reclaimed when the CSAs are reclaimed. The evidence established that the ditch and berm system, CSAs, and diversionary structure are capable of being constructed and functioning as designed. The reclamation plan includes avoidance (no mining) of approximately 3,100 acres, or twenty-nine percent, of the site, including more than seventy-one percent of the total wetlands on-site. Of this, 2,100 acres will be placed in a perpetual conservation easement. There is a wide gamut of habitat types on the site that will be preserved and not mined, including both streams and wetlands. The most complex and least impacted habitats on the site have generally been included in the preserve area. The project includes disturbance of 751.3 acres of wetlands and other surface waters, which include non-wetland floodplains, cattle ponds, and upland-cut ditches, and mining of 58,769 linear feet of natural and modified natural streams. An additional 1,661 linear feet of stream channel will be disturbed but not mined for six temporary crossings for dragline/utility/ pipeline corridors. To mitigate for impacts to streams and wetlands under the ERP rules, Mosaic will create 641 acres of wetlands and other surface waters and 67,397 feet of stream channel and will also provide a conservation easement to the Department on 2,100 acres of unmined wetland and upland habitat associated with the major riparian systems. The conservation easement area will be permanently preserved and protected from secondary impacts. The UMAM rule is applied to ERP applications to measure the functional loss to wetlands and other surface waters proposed for impact and the functional gain associated with the proposed mitigation. Functional loss is compared to functional gain to determine whether sufficient mitigation has been offered that offsets the proposed impacts. The proposed preservation and wetland and surface water creation, along with certain upland enhancements, will provide more than enough UMAM mitigation "lift" (with 48 excess credits) to satisfy the ERP mitigation obligations and offset those wetland impacts that cannot be eliminated or reduced. The UMAM scores for the reclaimed areas are conservative, that is, using higher risk factors by assuming muck or other appropriate topsoil will not be available, and take into account the risk or difficulty associated with creation of a particular system, based on actual UMAM scores for existing reclaimed systems. Time lag, which is normally a factor considered in the UMAM mitigation equation, expressly does not apply to phosphate mines pursuant to Florida Administrative Code Rule 62-345.600. Thus, Lee County's attempt to argue that some greater amount of mitigation of streams is required to account for the time required to construct and reinstate flow and vegetation to the streams is not credited. Mr. Cantrell confirmed that "fat" was built into the foot-for-foot stream reclamation because 7,000 more feet of stream will be reclaimed beyond the amount impacted; some "stream" segments, specifically, stream segment 18(i), probably should not have been required to be reclaimed at all. Under Florida Administrative Code Rule 62C-16.0051, the 511 and 512 classified "natural" streams are the only streams warranting reclamation as streams under the Department's reclamation rules. Only natural streams currently existing immediately prior to mining are required to be reclaimed on a linear foot basis. Reclamation meeting the requirements of Florida Administrative Code Rule 62C-16.0051 is adequate mitigation under the ERP program in Part IV, Chapter 373, Florida Statutes, if it maintains or improves the functions of the biological systems currently existing onsite. See § 373.414(6)(b), Fla. Stat. Mr. Cantrell established that, under subsection (5) of the rule, the Department has discretion to request the applicant to restore wetlands and streams to a different type of system than existing on the site if "mitigating factors indicate that restoration of previously modified streams as a different type of lotic system would produce better results for the biological system and water quality." The evidence established that the rules do not require reclamation of artificially created water courses or remnant stream segments that lack the functions or landscape position one normally associates with natural streams. Instead, a better lotic system will be created that will improve existing functions and water quality, consistent with Section 373.414(6)(b), Florida Statutes, and the CRP rules. In addition to the wetlands and surface waters created to meet mitigation requirements, the Project will also reclaim uplands and will include what is known as "land and lakes" reclamation in the southeastern portion of the site. Utilizing shaped and contoured overburden, Mosaic will create four lakes totaling 180 acres and 43 acres of associated herbaceous littoral zone as CRP reclamation. This is based predominantly on the mine-wide materials balance showing a need for reclaimed lakes to account for mine voids on the Hardee site, the Polk site, or both. As a result, Mosaic has proposed 180 acres of reclaimed lakes in Hardee County in lieu of 500 acres of reclaimed lakes in Polk County, as this results in eliminating overall reclaimed lake acreage while satisfying Hardee County's request for deep lakes. In addition, timing and property logistics in that portion of the site make transport of tailings to the area from the beneficiation plant problematic. As the site is an extension of the existing South Fort Meade Mine in Polk County, Mosaic possesses permits that are not at issue in this proceeding, but are relevant to the project. Discharges from a mine recirculation system require a National Pollutant Discharge Elimination System (NPDES) permit. Discharges may only occur at specified discharge points upon verification that the discharge meets stringent water quality conditions in the permit, which are set to ensure that water quality standards in the receiving water are met at the point of discharge (without mixing) and that downstream water quality will be protected. A separate NPDES permit is not needed for the Project, because Mosaic already has a valid NPDES permit for the Polk County beneficiation facility, which will serve the site. Mosaic currently has a Water Use Industrial Permit (WUP) issued by the Southwest Florida Water Management District (SWFWMD). The WUP includes both the Polk County and Hardee County portions of the South Fort Meade mine and governs both dewatering of the mine area prior to mining and operation of water supply wells located in Polk County that will be used to provide supplemental water to the recirculation system. Mosaic's evidence demonstrated that the Project will not cause adverse water quantity impacts, consistent with Florida Administrative Code Rules 40D-4.301(1)(a), 40D-4.302(1), and 62C-16.0051 and related BOR provisions. Mosaic presented evidence concerning the potential long term impacts of the proposed project on surface and ground water quantities and flows both during active mining and reclamation activities, and after reclamation is complete. Extensive analyses were presented by Mosaic's expert witnesses and evaluated by the Department. Such analyses showed no adverse impacts to water quantity on the site, adjacent properties, or in the Peace River or Charlotte Harbor. The site was studied extensively by Mosaic, and detailed hydrology characteristics were assessed as part of the preparation of the ERP and CRP applications. Various surface water stations, topographic maps, and ground water sampling points were utilized and geologic information was developed by evaluation of various borings across the site. Mosaic witness Burleson, a professional engineer, further considered soil types, land use and vegetative cover, and existing site hydrologic factors such as culverts, bridges, and other such changes to the site by the prior owners. Mosaic's modeling expert, Dr. Mark Ross, considered these factors on a regional scale in his integrated modeling for the 360 square mile regional basin. In the region of Florida that encompasses the site, there are three major hydrogeologic layers that are significant to a hydrologic analysis: (1) the surficial aquifer system, comprised of the overburden (the top layer of soil) and the phosphate matrix; (2) the confining layer and intermediate aquifer system; and (3) the Floridan, or deep, aquifer system. The confining layer separates the surficial from the intermediate and Floridan aquifer systems. By understanding the surface and ground water systems and physical characteristics of the site, the Mosaic experts were able to apply appropriately-calibrated hydrologic models to assess (1) pre-mining and post-reclamation floodplains and storm event runoff comparisons; (2) base flows to reclaimed streams; (3) potential hydrologic impacts of stream crossings; (4) effectiveness of the perimeter "recharge ditches"; (5) hydroperiod of reclaimed wetlands; and (6) potential impacts of the project on flows in the Peace River. These models were used to predict with reasonable certainty the effect of the Project on water quantity on-site, off-site, and on a regional scale. As set forth below, the evidence established that water quantity and flows in adjacent unmined wetlands and streams will be maintained during mining activities as a result of the installation of the ditch and berm system as proposed. Before the ditch and berm system is constructed, Mosaic will refine the design of the system based on actual geological data and gradient information to assure the ditch and berm will function as proposed and modeled. The ditch and berm system is inspected regularly. Recharge wells within the recharge ditch are not required unless localized conditions dictate use of the wells. Contrary to Lee County's assertions, this site is distinguishable from the Ona mine site (which is also in Hardee County), and the depth of mining is far more shallow with relatively few areas mined to a depth of fifty feet, which was common at the Ona mine site. Additionally, Mosaic must install perimeter monitor wells at regular intervals adjacent to and downgradient of the ditch and berm system prior to mining. These wells are monitored prior to mining to establish a baseline and regularly throughout mining in accordance with the requirements of Mosaic's WUP and the ERP to assure that the water table in adjacent areas is not adversely affected by mining activities. The water in the ditch portion of the perimeter system must be maintained at levels sufficient to maintain groundwater levels in undisturbed areas. Maintaining water in the ditch at appropriate levels precludes drainage of groundwater from adjacent sites into open mine cuts. Mosaic witness Pekas, a professional engineer, conducted modeling to determine whether adequate base flow will be provided to protected streams and reclaimed streams during mining. Provided the ditch and berm system is operated properly, proper base flows will be maintained. All of the hydrologic experts agreed that proper operation of a ditch and berm system assures that adequate groundwater outflow, or base flow, is available to support adjacent streams and wetlands during mining. During active mining operations, the ditch and berm system collects rainfall on areas within the system. The ditch and berm system temporarily detains this rainfall, preventing the direct discharge of untreated, turbid runoff to adjacent wetlands and waters, but does not permanently retain the rainfall. The evidence demonstrated that most of the rainfall that falls on areas disturbed by mining and mining-related activities is detained by the perimeter ditches, routed to the mine recirculation system, and is subsequently discharged, when it meets water quality standards, through NPDES-permitted outfalls to waters of the state. This will serve to attenuate surface water flows, allowing surface water retained during storm events to be discharged during extreme low flow events, providing for less "flashiness" in the streams. Lee County's assertion that runoff will be permanently retained is not credited; the evidence clearly established that controlled releases of treated stormwater occur through the permitted NPDES outfalls. The evidence shows that Mosaic will re-connect mined and reclaimed areas at the mine in Polk County at a rate exceeding the rate at which the Project's mine areas will be diverted by the ditch and berm system. Thus, any potential downstream impact of the ditch and berm construction on the site will be offset and buffered beyond the safeguards incorporated in the project design. The evidence demonstrated that the proposed ditch and berm recharge and monitoring system described here is capable, based upon generally accepted engineering principles, of being effectively performed and functioning as proposed and will preclude any adverse impact on the surficial aquifer beneath the preserved areas and adjacent properties and on adjacent surface waters and wetlands. The Department will apply the relevant BOR criteria concerning water quantity impacts on a pre-mining/post- reclamation basis consistent with the application of these same criteria to other non-mining ERP applicants. In this case, the Department reviewed Mosaic's submittals, assessed the impacts, and determined no adverse impacts to water quantity would occur during mining. Mosaic submitted a detailed analysis of potential surface water quantity impacts that may occur after reclamation is complete. This analysis included evaluation of post- reclamation floodplains and storm event run-off compared to pre- mining patterns, and characteristics of reclaimed natural systems. Floodplains, run-off, and reclaimed natural systems were assessed in the manner described below. Mosaic modeled potential impacts of the project on surface water flow using existing site conditions to calibrate and verify the model. Mr. Pekas developed a water balance hydroperiod spreadsheet model calibrated using existing, on-site wetlands to evaluate the expected hydroperiods of various types of wetland systems proposed to be reclaimed at the site. The evidence shows that the Pekas spreadsheet model was an appropriate model for predicting hydroperiods for reclaimed wetlands. Appropriate ranges for the expected hydroperiods and other hydrological characteristics needed for the different types of wetland systems to be created in the post-reclamation landscape were established. In order to reflect natural conditions, the Department specifically requested that the targets for expected hydroperiods of reclaimed wetlands vary across the established range of the hydroperiod for the type of wetland at issue, and these target hydroperiods are summarized in Table E-6 to the draft ERP. Mosaic demonstrated and verified that the Pekas spreadsheet reasonably predicts the hydroperiods to be expected from a given design for a proposed reclaimed wetland. After mining, site-specific conditions such as hydraulic conductivity will be reassessed and final design parameters will be developed accordingly. Lee County's witness Jonas demonstrated the importance of hydraulic conductivity when she adjusted the value for wetland 2-1C (one of Mr. Pekas' verification wetlands) from 0.5 to 30, based on a value not from the Project site, but from an off-site reclamation project. Not surprisingly, she concluded that a conductivity of 30 would not provide hydrology to support the wetland functionality. Her analysis demonstrates the importance of requiring reclamation of subsurface hydrology not based on an off-property conductivity value, but on site- specific hydraulic conductivity information. In his own analysis, Mr. Pekas relied on actual soil borings on-site, and at wetland 2-1C the average hydraulic conductivity was 0.5, which when modeled, provided appropriate hydrology for that wetland. Furthermore, ERP Specific Condition 11 requires Mosaic to reclaim wetlands with functionally equivalent hydraulic conditions based on verified field information as to site- specific hydrologic properties existing after mining, and the wetlands will not be released until functioning as required. The preponderance of the evidence demonstrates that reclaimed wetland can be designed and built in a manner that will achieve the required hydroperiods for each wetland type proposed to be disturbed and reclaimed at the site, including the bay swamps. In addition, each of the wetlands must be individually evaluated immediately prior to construction to provide additional verification of site-specific hydrologic conditions to assess, re-model, and verify the final wetland designs prior to construction. Condition 11c of the draft ERP also requires Mosaic to mimic the existing hydraulic conductivity and gradients near streams to ensure that base flows will be present post-reclamation. All of this will ensure that reclaimed streams will be hydrologically supported, and wetlands with the target hydroperiods requested by the Department will be constructed. The contrary testimony of Lee County's hydrologists does not credibly rebut this evidence. In performing their calculations, they utilized unrealistic numbers. The claim of Lee and Sarasota Counties' experts that they lacked sufficient information to form an opinion as to the accuracy of the modeling is not sufficient to overcome the evidence submitted by Mosaic to meet this criterion. See, e.g., National Audubon Society, et al. v. South Florida Water Management District, et al., DOAH Case No. 06-4157, 2007 Fla. ENV LEXIS 164 at *21 (DOAH July 24, 2007, SFWMD Sept. 13, 2007). Mr. Burleson determined that the original drainage patterns of the site would be restored post-reclamation. Mosaic provided reasonable assurances that the proposed reclamation is capable of being constructed and functioning as proposed. The preponderance of the evidence demonstrated that the proposed mining and reclamation of the site will not cause adverse water quantity impacts post-reclamation, as addressed by Florida Administrative Code Rules 40D-4.301(1)(a) and (c), associated BOR provisions, and Florida Administrative Code Rule 62C-16.0051(8)(b). Mosaic presented evidence demonstrating reasonable assurances that the proposed project will not cause adverse flooding to on-site or off-site property, consistent with Florida Administrative Code Rules 40D-4.301(1)(b) and 62C- 16.0051(8) and associated BOR provisions. During mining, there is no reasonable likelihood that active mining and reclamation activities at the site will result in any increased flooding conditions upstream of, on, or downstream of the site. The ditch and berm system reduces direct surface water runoff from areas disturbed by mining operations during peak rainfall events. Subsequent NPDES discharges of water typically lag slightly behind the rainfall events. This lag during mining decreases peak discharges in adjacent streams while augmenting lower flows slightly, thereby attenuating peak flows. Mr. Burleson evaluated the pre-mining and post- reclamation peak flow analyses for the project site to determine whether the post-reclamation topography, soils, and vegetative cover would result in flooding, using the Interconnected Pond Routing program or "ICPR" model, an accepted model for stormwater modeling, as required by the BOR. Mosaic's evidence established that the Project will not adversely impact existing surface water storage and conveyance capabilities, consistent with Florida Administrative Code Rule 40D-4.301(1)(c) and related BOR provisions. Additionally, Mosaic proposes to preserve from mining the 100-year flood plain of Little Charlie Creek and the Peace River and most of the higher quality small tributaries on the site. The smaller streams to be mined will be restored in a way that maintains or improves pre-mining conditions and will not cause harmful or erosional flows or shoaling. The federal Hydrologic Engineering Center Reservoir Analysis System and the National Flood Frequency Program were used by Mr. Burleson to verify the floodplains are accurately mapped and also that there will not be an increase in flood risk in the post-reclamation condition. The preponderance of the evidence demonstrates reasonable assurances that the proposed mining and reclamation activities at the site will not result in adverse flooding impacts, consistent with Florida Administrative Code Rules 40D- 4.301, 40D-4.302(1)(a)3., and 62C-16.0051(8), and the BOR, including water quality standards in Chapter 4. The evidence presented by Dr. Ross established that the proposed mining and reclamation activities on the site will not adversely impact flows in the Peace River. No adverse effects of the Project will be observable at the Zolfo Springs United States Geological Survey (USGS) gauging station. A minimum flow for the Upper Peace River has been established pursuant to Section 372.042, Florida Statutes. A minimum low flow of 45 cfs from April to June (Upper Peace MFL) was established at Zolfo Springs by the SWFWMD; since the MFL has not been met since adoption, a recovery plan has been instituted. See Fla. Admin. Code R. 40D-8.041(7). Lee County asserts that the Project will violate the Upper Peace MFL and the recovery plan, arguing that a reduction in average annual flow, regardless of how infinitesimal, constitutes a violation of Florida Administrative Code Rule 40D-4.301(1)(g). This argument was refuted by Dr. Ross, who established that the project would increase flows during low flow periods. The Department concurred with, and the evidence supports, Dr. Ross' assessment that the project would not exacerbate the Upper Peace MFL or interfere with the recovery plan. Dr. Ross created a regional-scale integrated model utilizing public domain computer programs in an iterative fashion that coupled surface water and ground water to comprehensively evaluate the effects of the project on the flows in the Peace River post-reclamation. The regional approach included a full range of upstream and downstream influences on the site, not simply mining, that could affect the hydrologic evaluation of any impacts from the Project on the Peace River. The model domain included 360 square miles. To account for site-specific impacts in the model, Dr. Ross increased the refinement and discretization over the site. Thus, the model was capable of considering impacts from the site in its entirety within the region as measured at the Zolfo Springs USGS gauging station. Zolfo Springs is the first USGS gauging station directly downstream of the site and is the point of compliance for minimum flows adopted for the Upper Peace River system. The regional model predicted virtually no change in flows at the Zolfo Springs gauging station after the project as proposed is reclaimed, and that both the high and low flows observed at Zolfo Springs would be maintained post-reclamation. Dr. Ross concluded that there would not be any reduction of low flows at Zolfo Springs due to the Project. He further concluded that the Project will not impact or affect the recovery of minimum flows. Dr. Ross calculated the differences between the model- predicted high flows and low flows from the observed flows and found that the modeled high flows were slightly attenuated and the modeled low flows were slightly augmented at Zolfo Springs. The attenuation is consistent with the increased storage for water in the post-reclamation system. Consistent with Florida Administrative Code Rule Chapter 40D-8, the Department considered potential impacts to low flows as the determining factor in determining whether a minimum low flow requirement like the one set for the Upper Peace MFL will be met. It concluded that the project is consistent with the Upper Peace MFL and its recovery strategy. The recovery strategy discusses projects which, like the one proposed, would yield a long-term increase in low flow conditions by storing some peak flow volumes and releasing them in low flow conditions. The Department's interpretation of its ERP rules and BOR provisions regarding MFLs, as well as other governing rules, is reasonable and has been accepted. Lee County's experts based their MFL testimony on an inappropriate use of annual average flow information and improper interpretation of Mosaic's data. Further, they inappropriately attempted to reach conclusions by estimates and extrapolation, and the overall weight of the evidence supports Mosaic's evidence that mining and reclamation will not cause a violation of the Upper Peace MFL. Accordingly, Mosaic has provided reasonable assurances that the requirements of Florida Administrative Code Rule 40D- 4.301(1)(g) and associated BOR provisions have been satisfied. The ditch and berm system and other proposed BMPs, such as silt fences, at the site will provide water quality protection to adjacent undisturbed surface waters and wetlands during mining and reclamation activities. The actual construction of the ditch and berm and stream crossings will be conducted using BMPs to avoid adverse construction-related impacts. During mining, the ditch and berm system will preclude uncontrolled releases of turbid water to adjacent un-mined areas. The evidence established that the proposed Project will not cause a violation of water quality standards, either in the short-term or long-term. Dr. Durbin, an ecologist, evaluated water quality data from the existing South Fort Meade mine in Polk County and compared data from the 10-year period before the mine opened against the 10-year period after the mining began, finding water quality to be equivalent or better after mining began in Polk County. This allowed him to conclude that water quality on the site will not be adversely affected and, in light of existing agricultural activities, will be maintained or improved both during mining and post-reclamation; water quality in reclaimed systems will be sufficient to maintain designated uses of the systems. Dr. Durbin opined that the ERP contains detailed water quality monitoring requirements that, based on his long experience, are sufficient to establish a baseline, assess compliance, and detect significant trends. Sarasota County's witness has no experience in ERP or CRP permitting and his suggestion for far more frequent monitoring is not credited. No additional monitoring conditions or criteria are warranted. For the above reasons, Mosaic has demonstrated by a preponderance of the evidence that reasonable assurances that water quality standards will not be violated either during mining, while reclamation is underway, or post-reclamation. The evidence further established that accepted BMPs will be used during mining to protect the water quality of adjacent and downstream waters, and that these measures can be expected to be effective to prevent any violations of water quality standards. Dr. Durbin provided unrebutted evidence that water quality standards in waters of the state and downstream of the project will be met post-reclamation and existing water quality in the unmined and reclaimed wetlands and waters will be maintained or improved post-reclamation. Thus, no adverse water quality impacts to the Peace River or Charlotte Harbor will occur during mining or post-reclamation. Therefore, reasonable assurances have been given that the requirements of Sections 373.414(1) and 373.414(6)(b), Florida Statutes, Florida Administrative Code Rules 40D- 4.301(1)(e) and 62C-16.0051(7), and associated BOR provisions are satisfied as to water quality. There is a wide range of habitat types on the site that will be preserved and not mined, including both streams and wetlands. The most complex and least impacted habitats on the site have generally been included in the no-mine and preserved areas. Mosaic does not propose to mine all or even most of the jurisdictional wetland and surface waters. In fact, seventy-one percent will be avoided. When developing a mining plan, Mosaic considers how to eliminate or reduce proposed impacts to waters and wetlands. The evidence established that Mosaic and the Department engaged in a protracted elimination and reduction discussion throughout the review process associated with the site's ERP/CRP applications. BOR Section 3.2.1 emphasizes the effort required to assess project design modifications that may be warranted to eliminate and reduce impacts to ecological resources found on the site. This effort was undertaken with the Department as early as 2004 during the DRI pre-application conferences. The major project design modifications involved the preservation of the named stream channels, the 100-year floodplain of the Peace River and Little Charlie Creek, and the 25-year floodplain of the other named tributaries. These areas will be permanently preserved by a 2,100-acre conservation easement; 1,000 additional acres will remain unmined. Also, the project design was modified and developed to maximize resource protection by integrating the Polk and Hardee mining operations. The testimony established how the activities at the Hardee operation will be greatly facilitated by relying upon and using the beneficiation plant and infrastructure already in place and permitted at the Polk site. Almost fifty percent of the clays generated at the Hardee mine will be disposed of in the existing Polk County CSAs, thereby eliminating one CSA altogether and substantially reducing the footprint needed for CSAs on the site. Likewise, the Department established that mine-wide, approximately 320 acres of lakes were eliminated. The Department discussed further modifications to the mine plan with Mosaic throughout the lengthy review process, doing a wetland and stream-by-stream assessment of the functions provided and the reclamation capability to maintain or improve the functions of the biological systems present prior to mining. The balance was struck between temporary resource extraction, recognized by Florida law as inextricably related to wetland disturbance, and the significantly altered natural resource features found on the site. In light of the 3,100 acres already eliminated and reduced from impact consideration, the Department in its discretion did not find it necessary to pursue economic data or analysis on the "practicability" of any further reductions. The highly disturbed nature of the wetlands and other surface waters being impacted gave the Department a high degree of confidence that mitigation and reclamation of these areas would in fact maintain and improve the functions provided prior to mining. Specifically, Mosaic has eliminated impacts to stream systems to the greatest extent practicable. Based on a Department field evaluation in late August 2008, Mosaic was directed to revise the no-mine line in the 3A stream system to more accurately reflect the floodplain of the stream draining the two bay heads north of the stream. In October 2008, Mosaic made the revision to add approximately 2.7 acres to the no-mine area. The majority of the streams proposed for impact by mining cannot be avoided, given the location of the three CSAs that are required for clay disposal associated with mining. The evidence established that there is no other location for the three CSAs that will have a lesser ecological or public health, safety, or welfare impact than the proposed location, given the site topography. As noted above, the volume of clays to be disposed of on the site has been reduced by half, and three CSAs are still needed. The location was chosen to move the CSAs as far from the Peace River and Little Charlie Creek as possible in light of the site topography, and this location avoids all impacts to named stream systems. As set forth above, Mosaic has demonstrated by a preponderance of the evidence that the best and most complex habitats on the site have been preserved at the expense of a loss of a significant amount of phosphate reserves in the preserved areas. All significant stream systems have been avoided to the extent practicable in light of the necessary CSAs. Both Mosaic and Department witnesses testified that the proposed no-mine area was the result of design modifications to eliminate or reduce impacts to wetlands to the greatest extent practicable. This satisfies the requirements of applicable rules and Section 373.414(1)(b), Florida Statutes. Florida Administrative Code Rule 62C-16.0051(4) and (5) provides specific guidance on the classification and reclamation of natural streams. The Department provided direction to the applicant through the review process in the identification of natural streams and the design guidance manual to ensure foot-for-foot replacement and functional replacement or improvement. The permit reflects the 58,769 feet of the streams identified as numbers 511 and 512 to be impacted, and Mosaic has proposed approximately 65,700 feet of restored stream. Lee County's assertion that 2.3 miles of additional unmapped streams should be added to the reclamation obligation has been rejected. It is clear many of the areas alleged to be unmapped streams were depressions, low lying areas, or standing water within wetland areas more accurately identified as marshes or swamps. The fact that a discernible natural stream channel exists upstream and downstream of a wetland did not change the accuracy of acknowledging the different structure, form, and functional attributes that result in the wetland being distinct from the stream. Also, many of the alleged unmapped streams were located in the no-mine areas, and thus the alleged lack of delineation is of no consequence. Lee County's witness Erwin admittedly took no measurements of the alleged streams. Also, he provided no evidence that he or his staff delineated the alleged streams on- site. Rather, he reconstructed where they were located as a desktop exercise from memory, without any aids or tools used in the field. He then superimposed an alignment and put it on a GIS layer over an aerial photograph, resulting in an electronically generated approximation. The witness offered no physical evidence of depth, width, length, or bankfull width of stream function, but merely an assertion as to areas that appeared to have a bed or channel, even if dry, and the attributes or functions of a stream were immaterial or irrelevant to his analysis. No other independent witness attested to the alleged stream discrepancy, whereas both Mosaic's expert, Mr. Kiefer, a recognized fluvial geomorphologist, and the state's expert on jurisdictional delineations, Mr. Cantrell, who was the author of the applicable rules, expressly disagreed with these allegations. The testimony of Mosaic and the Department is found to be the most persuasive on this issue. Mosaic and the Department established that the proposed stream restoration plan is more than adequate to meet the requirements of Florida Administrative Code Rule 62C- 16.0051(5) and will ensure the reclaimed streams maintain or improve the biological function of the streams to be impacted. Dr. Janicki, a scientist who testified on behalf of Lee County, was critical of the stream restoration plan. However, he acknowledged he was not an expert in stream restoration and that part of his job was to "look at how we might improve . . . on some of those shortcomings in the [stream] restoration plan." Dr. Janicki incorrectly assumed the design curve numbers were based on regional curves from north and northwest Florida rather than site-specific measurements. He stated that the guidance document was generalized and lacking specificity, but Table 4 contained in the guidance document contains nineteen stream morphological parameters for all forty- nine of the stream segments to be reclaimed. Dr. Janicki has never designed nor implemented a stream restoration project, and he acknowledged that he is not a fluvial geomorphologist. Conversely, Mosaic witnesses Boote and Kiefer, both accepted in this area, stated unequivocally that the plan was sufficiently detailed and that a qualified restoration and construction contractor could implement the plan in the field with appropriate field adjustments and construction level refinements based on site conditions. The allegation that the plan does not comport with ERP and CRP requirements because it lacks sufficient specificity is not credited. First, the ERP rules do not contain stream-specific restoration criteria. Second, the CRP stream rules adopted in May 2006 have never been applied in a prior case, and in this case the Department determined in its discretion that the plan as proposed meets the stream reclamation requirements of the CRP rules. Similarly, the stream restoration plan was criticized because measurements from every single segment or reach of stream were not used to develop the post-mining stream. However, Mr. Boote and Mr. Kiefer confirmed that only the most stable and least impacted of the stream segments on site were used as templates for stream reclamation. None of the recognized stream experts suggested that erosive, unstable "F" and "G" classified stream segments should be replaced in that unstable form or used as the template for reclamation. By a preponderance of the evidence, Mosaic has established that the reclamation plan for the site will more than offset any adverse impacts to wetlands resulting from the mining activities, because it will maintain or improve water quality and the functions of biological systems present on the site today, as required by Sections 373.414(1) and 373.414(6)(b), Florida Statutes. The evidence established that applicable Class III water quality standards will not be violated and that the water in wetlands and surface waters on-site post-reclamation will maintain or improve and be sufficient to support fish and wildlife in accordance with Florida Administrative Code Rules 62C-16.0051 and 40D-4.301(1)(e) and relevant BOR provisions. The proposed mitigation will also restore a more appropriate or more natural hydrologic regime that will allow for a better propagation of fish and invertebrates in reclaimed systems. The reclamation plan will maintain the function of biological systems of wetlands to be mined on-site by replacing the wetlands to be impacted with wetlands of the same type and similar topography and hydrology in the post-reclamation landscape. In many cases, it will enhance the function of those systems by improving the landscape position of the wetlands, relocating them closer to the preserved Little Charlie Creek corridor, and moving cattle ponds and pasture away from the corridor. Likewise, the existing streams proposed for mining will be replaced with stream reaches modeled on streams that are comparable or better than the existing, unstable, and eroded streams. The Department has determined that Mosaic can reclaim the streams and wetlands to at least as good as or better than existing condition on the site. Mosaic has provided reasonable assurances that the proposed reclamation plan will maintain or improve the existing function of biological systems. Mosaic's reclamation plan for the site therefore satisfies the mitigation requirements of Part IV, Chapter 373, Florida Statutes, and the implementing regulations and the BOR, as applied to phosphate mining activities through Section 373.414(6)(b), Florida Statutes. Through the testimony of witnesses Durbin, Kiefer, and Simpson, as well as documentary evidence, Mosaic has established that the proposed project, as reclaimed, will cause no adverse impacts on the value of functions provided to fish and wildlife and will not adversely affect the conservation of fish and wildlife, including endangered or threatened species and their habitats, as required by Section 373.414(1)(a)2., Florida Statutes, Florida Administrative Code Rules 40D- 4.301(1)(d) and 40D-4.301(1)(a)2., as well as the associated BOR Section 3.2.2 provisions. Likewise, the CRP criteria pertaining to fish and wildlife will be met. See Fla. Admin. Code R. 62C- 16.0051(11). Mosaic's reclamation and site habitat management plan will maintain or improve the functions of the biological systems on the site with respect to fish and wildlife, including threatened and endangered species and their habitat. Mosaic witness Simpson provided unrebutted testimony that the proposed mining and reclamation will not have adverse impacts on wildlife populations or conservation of wildlife including threatened or endangered species and their habitats and that proposed reclamation would maintain or improve wildlife habitat values. The evidence shows that the mining and reclamation will not have adverse impacts on fish populations or conservation of fish. The fish habitat on the site will either be preserved or, if mined, will be replaced with in many cases superior habitat. There will be a net increase in suitable fish habitat post-reclamation. The wetland and stream fish habitats on the site will provide appropriate habitat for the fish and wildlife that can be expected to occur in the region. The sampling described above can be expected to reflect the majority, if not all, of the fish species reasonably expected to be present on the site. Mosaic witness Durbin further confirmed that the fish species collected on-site are consistent with similar sites in the immediate vicinity with similar agricultural usage with which he is familiar. In August and September 2008, verification of that fish sampling effort was performed by Dr. Durbin, an outside consulting firm (ECT), and the Department. They confirmed that the fish collection efforts reasonably reflect the native and exotic fish species that are likely to occupy the site. Through the testimony of Dr. Fraser, Lee County compared two streams on the Ona mine site with three stream segments on the Project site. However, the sole basis of the witness' comparison was recollections of field work he participated in over four years ago and photos taken at that time compared with photos taken at the new site. The witness conceded that he did not consider or compare sedimentation levels in the two stream systems. On the other hand, Department witness Cantrell established that the streams compared by Dr. Fraser were dissimilar. In fact, one of the streams Dr. Fraser held up as an apparent example of prime aquatic habitat was Stream 20C, which Mr. Cantrell demonstrated is nearly completely choked by sand and sedimentation. All of the streams proposed for impact are first or second order streams; most of them are intermittent, carrying flow only seasonally and therefore are only periodically occupied by fish and macroinvertebrate communities. The fish that do tend to utilize such systems in the wet season tend to be very small, usually less than one inch in size. The proposed preservation will preserve the best aquatic habitat on the property; the streams to be preserved are the main pathways and aquatic habitats utilized by fish. Mosaic witnesses Durbin, Keenan, and Kiefer all testified that the reclamation plan will restore better aquatic habitat for fish and other aquatic organisms than exists presently on site on a greater than acre- for-acre, type-for-type and linear foot basis. They further testified that the proposed reclamation will provide better aquatic habitat for fish and wildlife than currently provided, consistent with both ERP and CRP requirements. In addition, Dr. Fraser's suggestion that the fish sampling done on the site was insufficient and that the ERP should be modified to require fish collection as a success criterion for the reclaimed streams is not credited. This is because such a proposal is not a requirement of the ERP or CRP rules. Dr. Fraser's comparisons of reclaimed to unmined streams were inconsistent with his own anecdotal fish observations, and he testified as to the difficulty of ensuring adequate fish sampling or knowing where fish will be on any given day, given their mobility. Also, he provided no comparisons as to how the reclaimed streams sampled are constructed compared to the plan for the site and admitted he did not know how or when they were built. Dr. Fraser's discussion of fish in basins where mining has occurred was discredited by his own data showing that no reduction in the number of native fish species has occurred over time in those basins. Mosaic's reclamation plan, which consolidates the native upland and wetland habitats along the Little Charlie Creek corridor, will improve the fish and wildlife function of those systems and increase fish and wildlife abundance and diversity, as set forth above. There will be no adverse impacts to fish and wildlife and their habitat or to the conservation of fish and wildlife, including listed species, post-reclamation, because the fish and wildlife function of the tract will be maintained and in many cases improved by the reclamation and habitat management plans. This is particularly true in light of the existing condition, hydrologic connection, location, and fish and wildlife utilization of the wetlands and surface waters on site. Therefore, Mosaic has provided reasonable assurances that the requirements of Section 373.414(1)(a)2., Florida Statutes, Florida Administrative Code Rules 40D-4.301(1)(d) and 40D- 4.302(1)(a)2., and the relevant BOR provisions have been satisfied. Mosaic demonstrated that it has reclaimed wetlands, uplands, and streams consistent with the regulatory requirements and permit conditions in place at the time the area was reclaimed. Indeed, many of these reclaimed areas, whether or not under different ownership and control or whether released from further regulatory requirements, continue to demonstrate that they are successful and functioning ecosystems. The reclamation proposed for the site is state-of- the-art, reflecting the most recent evolution of reclamation techniques for uplands, wetlands and streams, with more planning and detail that should achieve the reclamation goals faster. Many older wetland projects were designed to meet a +/- 1-foot contour and were designed with older generations of equipment and survey techniques. However, Mosaic's third party contractor's bulldozers/tractors are now equipped with GPS and sensors to enable grade tolerances within two inches, allowing for much more accurate backfilling and wetland construction. Accordingly, Mosaic's newer wetlands contain both deep and shallow areas with gradation/zonation in between. Hydrologic regimes and hydroperiods can thus be effectively created to target and achieve more specific hydrologic conditions required by certain wetland systems such as seepage slopes and wet prairies. Nonetheless, the projected UMAM scores for the reclaimed systems take into account a higher risk factor for systems that historically were more difficult to reclaim. Mosaic has provided reasonable assurances of its ability to restore the hydrology and types of vegetation found on the site and of its ability to create ecosystems that will maintain or improve the function of the biological systems proposed for mining on the site. Mosaic has restored wetlands in a variety of configurations ranging from small round depressions of less than a few acres to large complex polygons in excess of two hundred acres, as well as wetlands with low slope gradients. For example, Mr. Kiefer described and depicted Mosaic's ability to restore a bay swamp at point 84(5) at the Fort Green Mine and at Alderman Bay. Lee and Sarasota Counties focused on bay swamps in particular, but failed to acknowledge that Mosaic will be reclaiming 98.5 acres of bay swamps while only impacting 62.1 acres. Mosaic demonstrated that herbaceous and forested wetlands can be and have been restored by Mosaic and its predecessors. Mosaic has demonstrated that it can restore the various zones and depths of freshwater marshes, including shrub marshes, from the deep emergent zone to the wet prairie fringe, and has demonstrated that these zones in reclaimed marshes are providing important and key wetland functions, such as water quality, food chain support, habitat, and other functions, similar to those functions provided by site marshes. This evidence was not effectively rebutted by Lee or Sarasota Counties. In fact, Sarasota County witness Lipstein acknowledged Mosaic is proposing to mitigate for all impacts. When asked if the proposed bay swamps will be successful or unsuccessful, she replied that she did not know and, "you will have to just wait and see if it reaches that success criteria." There have been different success criteria applied in Department permits over the years, and Mosaic has demonstrated the ability to meet those changing and more stringent criteria. In the past, stream restoration was accomplished relatively simply by contouring the stream valley and floodplain to support wetland vegetation, then allowing a flow channel to self-organize. While this technique has resulted in successful streams that met Department permit criteria, it can take many years to occur. For example, Dogleg Branch (which is located on the site of another mining operation) took almost twenty years to achieve success. Mosaic has previously developed successful stream restoration projects which have been documented to provide flow regimes similar to that of natural flatwoods streams, with in- stream aquatic habitat diversity similar to or better than the stream segments proposed for mining at the site and which met reclamation criteria. Mosaic witness Kiefer demonstrated this with evidence of the functions that various reclaimed streams provided. He also showed that, in newer stream restoration projects, like Maron Run, certain functions and form, such as habitat availability, bank stability, meander, and pool-riffle sequence, are developing rapidly. Also, Department witness Rivera testified to Mosaic's commitment to achieving stream success in its efforts to retrofit certain of these earlier reclaimed streams to achieve greater function and habitat diversity. Using an average sinuosity of 1.35, over 65,700 linear feet of streams will be created as part of the mitigation plan. The foot-for-foot requirement for the reclaimed streams will be exceeded by 7,000 feet. Mosaic's mitigation proposal incorporates state-of- the-art stream restoration techniques and the post-reclamation topography to be used as guidance for the final construction plans. The guidance is based on extensive data collected from twenty-one cross sections of reference reaches within the project area, including measurements for channel dimensions, sinuosity, bankfull, and entrenchment ratios. Snags, debris, and other woody material will be placed at appropriate intervals within the channel to provide in-stream habitat and aid in-channel stabilization and development. Restored streams will have primarily forested riparian zones. Trees will be planted using techniques that will assist rapid canopy closure and aid in rapid bank stabilization. Biodegradable erosion control blankets will be used to control erosion. The streams will be designed such that the stream morphology fits within the Rosgen Stream Classification System (Rosgen) described in the reference reaches. To create a design template, Mosaic's experts carefully measured the important geomorphic characteristics of the stream segments to be disturbed. The plan incorporates, among other factors, design specifications for meander patterns, longitudinal valley and bed slopes, bank slopes, cross-sectional area, widths, depths, large woody debris, pools, riffles, bends, and sediment composition. It is the second known low-order stream creation plan in Florida to provide this level of detail. The stream plan represents an overall improvement upon the existing conditions at the site, as Mosaic is generally only mining small, shallow, intermittent stream segments of significantly lower ecological value and will create streams that are less erosive and will have greater in-stream habitat diversity and availability than the segments to be mined. Accordingly, the reclaimed streams segments will at least maintain and in many cases improve the ecological functions served by the existing segments. Special emphasis has been placed on assuring that post-reclamation soils are a suitable growing medium for the proposed reclaimed habitat. Soils will be used to closely mimic the native Florida soils profile. Mosaic witness Schuster established that proposed reclaimed soil conditions do not pose limitations on Mosaic's ability to create upland and wetland ecosystems. The soil reclamation plan uses parent materials available after mining in a sequence similar to the textural or horizon sequence in soils present at the site before mining. This soil profile will have a created topsoil layer as a suitable growing medium and subsurface layers whose thicknesses can be adjusted to achieve the drainage class, that is, hydraulic conductivity or permeability, that is needed to support the post-reclamation hydrology. The overburden used to form the lower part of the reclaimed soil sequence is native Florida soil and underlying geologic material. The overburden is excavated so that the matrix can be mined, but then the material is put back in the mined areas in a sequence that resembles native soil horizons. Where available, the top layer of the soil sequence will be a direct transfer of muck/topsoil pursuant to the permit conditions. Where donor topsoil is not available, other appropriate materials can be used if approved by the Department. Possible methods may include establishment of cover crops, green manuring, mulching, and sod placement, all of which have been demonstrated to provide organic matter and a suitable growing medium for reclaimed wetlands and will facilitate success of the wetlands. These methods comport with the requirements of Florida Administrative Code Rule 62C-16.0051(3). For reclamation, Mosaic will use various thicknesses of materials including sand tailings and overburden, depending on the area to be reclaimed and the needed hydraulic conductivity as dictated by the modeling that is required. Sand tailings will be utilized in native habitats. Sand tailings have a much higher rate of hydraulic conductivity than overburden, which is low, but not impermeable. Reclaimed soils behave similarly to native soils. On site development of soil morphology at reclaimed sites has occurred, including organic matter accumulation in the topsoil formation of redox concentrations, and other components of soil structure, which evidence that the same natural processes are present in both reclaimed and native soils. Lee County's witnesses incorrectly assumed an overburden cap that will not be present. Mosaic has provided appropriate cost estimates for financial assurances of reclamation and has satisfied the BOR requirements of providing third-party estimates and draft financial assurance documentation. The first three years of mitigation at one hundred ten percent is $3,957,356.00. This amount is determined to be sufficient. Lee and Sarasota Counties' witnesses could provide no contrary cost estimates of actual comparable large-scale projects. The proffered costs of Lee County witness Erwin were rejected in another mining case (the Ona case), they ignore the definitions of "waste" and "mining operations," and they assume mitigation requirements not found in the BOR. The evidence supports a finding that all adverse impacts, including any secondary impacts, associated with the Project will be temporary and will be offset by the proposed reclamation. All of the proposed impacts from the Project will occur within the Peace River Basin, and Mosaic's proposed mitigation will all occur within the Peace River Basin as well. Therefore, the cumulative impacts review requirements of Section 373.414(8)(a), Florida Statutes, and Florida Administrative Code Rule 40D-4.302(1)(b) are satisfied. The BMPs put into place will prevent adverse secondary impacts from occurring during mining, and no adverse secondary impacts are expected from the project post- reclamation. No secondary impacts to listed wildlife are reasonably expected to occur, based on the buffers and on the post-reclamation habitat that will exist. In summary, Mosaic has demonstrated by a preponderance of the evidence that the proposed project meets the permitting criteria of Florida Administrative Code Rule 40D-4.301 and associated BOR provisions. Florida Administrative Code Rule 40D-4.302(1)(a) requires reasonable assurances the proposed activities "will not be contrary to the public interest" as determined by balancing seven factors. See also § 373.414(1), Fla. Stat. For the reasons set forth below, the preponderance of evidence supports a finding that the public interest factors set forth in the statute and rule weigh in favor of issuing the permit. The Florida Legislature has recognized that phosphate mining "is important to the continued economic well-being of the state and to the needs of society." See § 378.202(1), Fla. Stat. Mosaic has demonstrated by a preponderance of evidence that both the public and the environment will benefit from the project as described above. Mining of the site will also result in a more general benefit to the public, including local residents. It is estimated that mining of the site will result in fifty million tons of recoverable phosphate rock reserves, which will be used to make fertilizer. Mosaic employs 272 people at its South Fort Meade facility and spends approximately $75,000.00 per employee per year for direct wages, benefits, and compensation. In addition, it has been estimated there are four to five persons employed in support industries for each direct Mosaic employee, considering contractors, vendors, and suppliers. The site project is expected to generate up to $23 million in severance taxes, tangible taxes, property taxes, and other benefits to Hardee County over the life of the mine. The evidence shows that the proposed activities will not cause adverse impacts to the public health, safety, or welfare or to the property of others. Fla. Admin. Code R. 40D- 302(1)(a)1. Witness Burleson established that the water quantity criteria in BOR Chapter 4 have been satisfied and that no flooding problems will occur. No environmental hazards or public health and safety issues have been identified. Section 373.414(1)(a)1., Florida Statutes, Florida Administrative Code Rule 40D-4.302(1)(a)1., and BOR Section 3.2.3.1 have accordingly been satisfied. The evidence established that the proposed mining and reclamation will not cause adverse impacts to the conservation of fish and wildlife or their habitat, including endangered or threatened species, satisfying Florida Administrative Code Rule 40D-4.302(1)(a)2. and BOR Sections 3.2.2, 3.2.2.3, and 3.2.3.2. The evidence shows that the proposed activities will not cause adverse impacts to navigation or flow and will not cause harmful erosion or shoaling. Fla. Admin. Code R. 40D- 4.302(1)(a)3. The evidence shows that the proposed activities will not cause adverse impacts to fishing or recreation or marine productivity, and the lakes will enhance fishing and recreation. Fla. Admin. Code R. 40D-4.302(1)(a)4. As a matter of law, Section 378.202(1), Florida Statutes, provides that phosphate mining is a temporary activity. Fla. Admin. Code R. 40D-4.302(1)(a)5. The parties have stipulated that there will be no adverse impacts on historical or archaeological resources. Fla. Admin. Code R. 40D-4.302(1)(a)6. The evidence shows that the current condition and relative value of functions of the site landscape have been significantly affected over time by agricultural activities, causing alteration of natural streams and wetlands and low fish and wildlife utilization. A preponderance of the evidence established that these negative impacts will be ameliorated by the proposed reclamation. Fla. Admin. Code R. 40D-4.302(1)(a)7. In light of the above, Mosaic has provided reasonable assurances that Section 373.414(1)(a), Florida Statutes, Florida Administrative Code Rule 40D-4.302(1)(a), and associated BOR requirements for the public interest test have been satisfied, and those criteria weigh in favor of issuing the permit. Section 373.414(6)(b), Florida Statutes, establishes the appropriate mitigation for wetland and surface water impacts associated with phosphate mines as follows: "Wetlands reclamation activities for phosphate and heavy minerals mining undertaken pursuant to chapter 378 shall be considered appropriate mitigation for this part if they maintain or improve the water quality and the function of the biological systems present at the site prior to the commencement of mining activities." Part III of Chapter 378, Florida Statutes, addresses phosphate land reclamation, and the Department has adopted specific regulations pursuant to this part, which are found in Florida Administrative Code Rule 62C-16.0051. For the reasons set forth below, Mosaic has demonstrated by a preponderance of the evidence that the reclamation and restoration standards in Florida Administrative Code Rule 62C-16.0051 have been met. The parties stipulated the Project will meet the safety standards in subsection (1) of the rule. Any temporary structures will be removed following mining and the area then reclaimed. Appropriate BMPs will also be installed. The Project will meet the backfilling and contouring requirements of subsection (2). Specifically, the evidence shows that the area will be backfilled and contoured to achieve the desired landforms; slopes will be no steeper than a 4:1 ratio; bank stabilization techniques will be used; and post- reclamation contouring and topography will help ensure that the reclamation plan and hydrologic response is successful. The reclamation will meet the requirement in subsection (3) that Mosaic use good quality topsoil when available and other suitable growing media to achieve the planned vegetative communities. The Project will meet the acre-for-acre requirement for wetlands because more acres of wetlands and surface waters are being proposed to be restored than will be impacted. The Department uses FLUCCS Category II to determine whether the minimum type-for-type requirement is met. Thus, the type-for-type requirement is met by looking at the forested wetlands acreage overall and the herbaceous wetlands acreage overall. Subsection (4) has been satisfied by the proposed CRP. While the herbaceous wetland fringe of the lakes is included in the acre-for-acre, type-for-type calculation, the open waters of the lake are not. The Project will meet the type-for-type requirement in the rule because, category-by- category, type-for-type, more than a 1:1 ratio of forested and herbaceous wetlands are being restored. As noted above, the wetlands and streams were mapped during the application process in accordance with the directives of the Department and the requirements of subsection (4). Where wetlands are directly associated with or adjacent to streams, restoration of both is integrated and included in the restoration plan. Non-wetland and wetland floodplains will be restored as directed by the Department in accordance with this rule. No natural lakes or ponds exist on site, thus the portion of this rule related to natural lakes does not apply. All natural streams proposed for impact will be restored foot-for-foot based on Rosgen Level II. More stream linear feet (65,700 feet) are being replaced than are being mined (58,769 feet). Therefore, the requirements of subsection (5) have been met. Subsection (6) has been satisfied after accounting for the Littoral Zone Variance described below authorized by Florida Administrative Code Rule 62C-16.0051(13). The design of the reclaimed wetlands and lakes will maximize beneficial drainage, provide fish and wildlife habitat, maintain downstream water quality, and incorporate a variety of vegetation and hydraulic zones. Greenbelts of vegetation are incorporated. Subsection (7) has been satisfied. There will be no water quality concerns either during mining or post-reclamation with the reclaimed streams, lakes, wetlands or other surface waters. Subsection (8) has been met; the Project is not expected to cause flooding, and the original drainage pattern will be restored to the extent possible. Subsection (9) has been satisfied with respect to waste disposal. Areas used for clay settling will be minimized, and only three CSAs are proposed for the site, as fifty percent of the clays generated at the site will be disposed of in previously-permitted CSAs in Polk County. Backfilling of mine cuts is the highest priority use for the site's sand tailings. No tailings will be sold. The evidence showed that sand tailings will not be permanently stored above natural grade, although temporary stock piles are authorized to facilitate reclamation. Reclamation of CSAs will occur as expeditiously as possible. Solid waste was not an issue in this proceeding. The revegetation proposed for the Project will succeed to achieve permanent revegetation and meets the requirements of subsection (10). Mosaic has submitted a plan for revegetation that lists species by species what will be replaced through planting or seeding into each of the different types of wetlands. The revegetation plan and planting tables provide clear guidance to the entire reclamation plan and will minimize erosion, conceal the effects of mining, and recognize the requirements for fish and wildlife habitat. Upland cover and forested upland requirements in the rule will be met under the CRP; the appropriate forested densities are set forth in the CRP and can reasonably be expected to be established within one year. Likewise, the wetland vegetative cover requirements in the CRP meet the rule requirements and can be easily met. As set forth above, the wetlands to be created are of the types Mosaic has successfully recreated in the past, and advances in reclamation and maintenance techniques will further ensure the vegetation plan is successfully implemented. The vegetative plans, including the stream plan, provide appropriate habitat for fish and wildlife. The best available technologies will be used to restore and revegetate wetlands. Furthermore, the vegetation plan meets and exceeds the requirements for the use of indigenous species. Native plants and grasses will be used in all native habitats. As required by subsection (11), measures have been identified and incorporated into the CRP to offset fish and wildlife values lost as a result of mining operations. Special programs to restore and/or reclaim particular habitats, especially for endangered and threatened species have been identified. A Site Habitat Management Plan has been incorporated to prevent adverse impacts to threatened and endangered species, and the proposed conservation easement and reclamation plan will protect and restore currently impaired habitat to a better condition. Specifically, Dr. Durbin testified with respect to the CRP requirements for aquatic species, including fish and macroinvertebrates; the best fish and wildlife habitat onsite will be preserved. Mr. Simpson testified regarding habitat preservation and reclamation activities, the proposed wildlife management plans, and the proposed enhancements to habitat that will benefit wildlife, including listed wildlife. Mosaic has sufficiently addressed the requirements of subsection (11) of the rule in the CRP. Subsection (12) has been satisfied. The proposed mining and reclamation schedule in the application documents comports with the rule requirements by including time schedules for mining, waste disposal, contouring, and revegetation, and the completion dates for such activities comport with the rules. Mosaic has proposed, and the DEP has indicated an intent to issue, the Littoral Zone Variance as an experimental technique to improve the quality of the reclaimed lakes pursuant to this subsection and Section 378.212(1)(e), Florida Statutes. Given the depth of the proposed reclamation lakes, Mosaic applied for, and the Department has proposed to grant, a variance from the water quality standard for DO in the lower portions of the lakes. The DO Variance from Florida Administrative Code Rule 62-302.530(31) is being sought pursuant to Sections 373.414(6)(a), 373.414(17), and 403.201(1)(a), Florida Statutes, which provide the minimum standards for DO levels in surface waters. Class III freshwater water quality standards apply to those portions of the site that constitute surface waters as defined by Florida law. For at least those reclaimed lakes that will connect offsite to downstream waters or wetlands (Lakes 1, 3, and 4), there is no dispute that Class III water quality standards would apply. The minimum water quality standard for DO in freshwater systems is 5.0 milligrams per Litre (mg/L). The evidence demonstrated that alternatives to the lakes in terms of both size and location were considered. The Department considered the proposed lakes as part of the elimination and reduction of overall wetland impacts on both South Fort Meade Polk and Hardee. On balance, it is a preferable alternative to use the available sand resulting from mining of the Hardee County portion of the South Fort Meade mine to eliminate lakes and create additional wetlands on the Polk County portion of the mine rather than utilize that sand to eliminate all lakes on the Hardee County portion of the site. This is especially true given the desire of Hardee County for recreational lakes and the Department's preference to reduce the overall acreage of the reclaimed lakes at the South Fort Meade mine. It is not feasible to make the lakes shallower given the available materials. There is no practicable means known or available for increasing DO in the deep pockets of lakes of the proposed depths that would not have a potential negative effect. This fact has been established and recognized by the Florida Legislature in Section 373.414(6)(a), Florida Statutes, which provides that the deep pits left by mining operations may not meet the DO criteria below the surficial layers of the lakes. The Legislature has further provided that a variance from the DO standard can be issued where deep lakes must be left as part of the reclamation plan. Id. The evidence established that lower DO levels may at times occur in the deep pockets of some of the reclaimed lakes to the same extent and effect as those lower levels occur in natural lakes of similar depths. This effect will occur only in the hypolimnion, or lower levels, of the lakes in the hotter summer months. The evidence likewise established that it is very unlikely that DO levels below 1.0 mg/L will occur at any time in any of the proposed reclaimed lakes. Provided the DO levels do not drop below 1.0 mg/L for any extended period of time, the only expected effect of the occasional seasonal reduction in DO in the lowest level of the reclaimed lakes will be to temporarily exclude fish from those lower portions of the lake during the summer months, which is also true of natural deep lakes. The evidence established that reclaimed lakes function well and provide habitat for fish and wildlife. Water quality standards will be met in all of the lakes other than occasional seasonal DO violations in the lower portions of the deepest lake. All water quality standards, including DO, will be met at all lake outlets and discharge points. All other applicable regulatory criteria will be met in the reclaimed lakes. Dissolved oxygen levels in the upper layers of the lakes are expected and required to meet the minimum DO criteria in Florida Administrative Code Rule 62- 302.530 and will be adequate to support healthy fish populations. The evidence showed no downstream impacts will occur due to the DO Variance for the lakes. The evidence showed reclaimed lakes support healthy fish and macroinvertebrate communities and provide recreational fishing opportunities. Even older lakes, such as the Tenoroc lakes (located in an old mining area in Polk County), provide substantial recreational fishing and wildlife utilization opportunities. This testimony was not rebutted. The evidence offered by Lee and Sarasota Counties as a means to increase DO levels in the reclaimed lakes actually demonstrated that artificially attempting aeration of a deeper lake can have negative environmental effects. Therefore, the testimony of witnesses Janicki and Merriam has not been credited. By a preponderance of the evidence, Mosaic proved entitlement to the DO Variance for the lakes pursuant to Sections 373.414(6)(a) and 403.201(1)(a), Florida Statutes. Given the location of the reclaimed lakes and as a means of experimenting with different reclamation planting techniques to create a variety of shorelines, Mosaic also applied for, and the Department has proposed to grant, a variance from the reclamation requirements in Florida Administrative Code Rule 62C-16.0051 pertaining to the planting of littoral shelves or zones around reclaimed lakes. The Littoral Zone Variance is being sought under Section 378.212(1)(e), Florida Statutes, from Florida Administrative Code Rule 62C-16.0051(6)(a) and (b), which provides minimum water zones for emergent and submerged vegetation, known as the littoral zones of the lakes. Subsection (6) of the rule provides for a twenty-five percent high-water zone of water fluctuation to encourage emergent and transition zone vegetation, and that a twenty percent low water zone between the annual low water line and six feet below the annual low water line to provide fish bedding areas and submerged vegetation zones. These vegetative zones are collectively known as the littoral zone of a lake. Traditionally, these percentages have been met in reclaimed lakes by sloping and creation of a uniform fringe of herbaceous wetland vegetation completely encircling the lake; however, such uniform fringes are not typical around natural lakes, which vary in composition and width. Rather than create a uniform band of vegetation around the lakes, Mosaic has proposed to reclaim the littoral zones around the reclaimed lakes by concentrating them in several broad, shallow areas, including the outlets of the lakes where such outlets occur (Lakes 1, 3 and 4). Of the proposed lakes, one will meet the littoral zone requirement, two will have over twenty percent of the total area in littoral zone, and the remaining lake will have a littoral zone of just under fourteen percent of the total area. The littoral zones will be reclaimed by constructing broad shelves of differing depths and planting the shelves with herbaceous wetland plant species. This design provides the environmental benefit of herbaceous vegetation at the outlet to provide increased filtration of nutrients or sediments of any water overflowing from the lakes during other high water events. This increases environmental benefits at the outlet of the lakes and has the potential to improve water quality downstream. Further, the proposed clustering of the littoral zones in several broad shallow shelves, rather than creation of a thin fringe around the lakes as is customary, will benefit wildlife and fish by creating a more extensive wetland ecosystem in lieu of the monoculture typically created by the thin littoral fringe. The proposed littoral zone clustering also creates more useable shoreline for boating, fishing, and recreational activities in the areas where the littoral zones are not clustered, with the added benefit of tending to separate the wildlife usage in the littoral zone clusters from the human usage in the upland forested areas of the shoreline where minimal littoral zones are planned. This is an experimental technique that advances reclamation methods by balancing habitat, water quality, and recreational considerations. Mosaic has demonstrated that the Littoral Zone Variance comports with Section 378.212(1)(e), Florida Statutes, and may be issued.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Protection enter a final order granting Mosaic's applications for the requested permits and variances.
