The Issue Are Petitioner’s outside water supply connections in violation of Rule 10D-26.120(2) and (3)(a), Florida Administrative Code, and, if so, should Petitioner be assessed an administrative fine for such violation?
Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant findings of fact are made: Petitioner is permitted by the Department in accordance with Chapter 513, Florida Statutes, to operate the Peace River Campground, (Campground) which is a Recreational Vehicle (RV) Park (182 spaces) and a Mobile Home (MH) Park (15 spaces), annual permit number 14-010-97. The Campground’s water is supplied by a community public water utility company. Each RV and MH space has an outside water tap as required by Chapter 10D-26, Florida Administrative Code. Many of the outside water taps do not have a backflow or back-siphonage prevention device installed on them. On February 6, 1997, the Department conducted a routine inspection of the campground and determined that the campground was in violation of Rule 10D-26.120(2) and (3)(a), Florida Administrative Code, for failing to have the required backflow or back-siphonage prevention. The citation required Petitioner to install backflow or back-siphonage prevention by February 28, 1997, the next scheduled inspection date. On February 28, 1997, the Department conducted a follow-up inspection of the Campground’s water system and determined that the alleged violation had not been corrected. Petitioner disagreed with the Department’s determination that the Campground’s water system was not in compliance with Rule 10D-26.120(2) and (3)(a), Florida Administrative Code, for failing to have the Campground’s water system designed or constructed to prevent backflow or back-siphonage. On February 28, 1997, the Department issued a citation of violation (citation) to Petitioner alleging a violation of Rule 10D-26.120(2) and (3)(a), Florida Administrative Code, for failing to have the Campground’s water supply connection designed or constructed to prevent backflow or back-siphonage. The Campground’s water connections at each RV and MH site have water taps which are above ground and have standard water shut-off valves. The Campground’s water system has good water pressure of approximate 70-100 pounds pressure per square inch (psi). The Campground’s outside water taps are neither constructed nor designed to prevent backflow or back-siphonage in the event the water pressure drops to a point which would allow backflow or back-siphonage, such as if the water main feeding the Campground’s water system broke. If the water pressure in the Campground’s water system should drop allowing backflow or back-siphonage, hazardous material could possible be injected in the water system. Although there has never been a recorded incident of backflow or back-siphonage into the Campground’s water system, without the some type of backflow or back-siphonage preventer being installed there remains a potential for this to happen. The Campground’s outside water connections would not prevent backflow or back-siphonage under certain conditions and are not in compliance with Rule 10D-26.120(2) and (3)(a), Florida Administrative Code. There are six basic types of devices that are recognized by the Environmental Protection Agency and the engineering profession which prevent backflow and back-siphonage. These devices are: (a) air gaps; (b) barometric loops; (c) vacuum breakers--both atmospheric and pressure type; (d) double check with intermediate atmospheric vent; (e) double check valve assembler; and (f) reduced pressure principle devices. The Department does not mandate which device the Petitioner must install, only that a proper device be installed which will prevent backflow or back-siphonage. A hose bib vacuum breaker such as Department’s Exhibit 3 provide the minimum protection against backflow or back-siphonage and is considered acceptable for compliance with Rule 10D- 26.120(2) and (3)(a), Florida Administrative Code.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Department enter a Final Order assessing an administrative fine in the amount of $150.00.

The Issue The issue in this case is whether the St. Johns River Water Management District (District) should issue a consumptive use permit (CUP) in response to Application Number 99052 filed by the City of Titusville and, if so, what CUP terms are appropriate.
Findings Of Fact Area II and III Wellfields On February 10, 1998, the District issued CUP 10647 to the City of Titusville, authorizing the withdrawal of an annual average of 6.5 mgd from the City's Area II and Area III Wellfields, 5.4 from Area II and 1.1 from Area III. These wellfields are owned and operated by the City and are located within its municipal boundaries. They produce water from the SAS. The Area II Wellfield is located near I-95 in the northeastern portion of the City and consists of shallow wells primarily constructed between 1955 and 2002. It consists of 53 production wells, of which 31 are considered to be of primary use. The City replaced 16 Area II production wells in 1995 and 4 production wells in 2000 and is currently considering the replacement of 4 additional wells. The Area III Wellfield is located in the south-central portion of the City’s service area. It consists of 35 production wells, of which 18 are considered to be of primary use. Petitioners contend that both the "safe yield" (the quantity of water the City can withdraw without degrading the water resource) and the "reliable yield" (the quantity of water the City can dependably withdraw) of the Area II and III Wellfields are the permitted limits of 5.4 and 1.1 mgd, respectively. The City and the District contend that saline intrusion into the SAS has reduced the safe and reliable yields to significantly less than the permitted amounts at this time. Historically, the Area II Wellfield was the most productive wellfield. Prior to 1988, the City relied entirely on the Area II Wellfield and pumped almost 5 mgd from it at times. Since then, several Area II wells have shown signs of water quality degradation that has resulted in a reduction in pumping to better stabilize water quality levels. For the past five years, the City has only pumped approximately 3 mgd on an annual average basis from the Area II Wellfield. Chloride concentrations exceeding 250 mg/l have been recorded in 16 Area II production wells. Chloride concentrations exceeding 250 mg/l have been recorded in 22 Area III production wells. About 10 wells in the Area II and III Wellfields have been abandoned because of water quality degradation. At the Area II Wellfields there are 10 wells whose use is impaired because of water quality issues. At the Area III Wellfields there are 15 wells whose use is impaired because of water quality issues. Area III has had serious chloride problems, with concentrations at or near 200 mg/l for much of the mid-90's. In the Area III Wellfield, the Anastasia wells have the best water quality. However, these wells have also seen increasing concentrations of chlorides, with one well over 200 mg/l. According to information introduced into evidence by the City, it appears that Area III began to have chloride problems primarily due to over-pumping.5 The City pumped far in excess of permit limits from Area III during the early 1990's, including almost twice the permit limit in 1990 and 1.5 times the limit in 1991. While chlorides were between 77 and 92 mg/l in 1990-92, they began to rise in 1993 and were between 192 and 202 mg/l for the rest of the decade. Area III production declined in 1997 to approximately 0.66 mgd and declined further to a low of approximately 0.5 mgd in 1999. In 2000, chlorides fell to approximately 138 mg/l and then rose to approximately 150 mg/l in 2002-04, while production gradually rose to close to the permit limit in 2002 and 2003, before dipping to 0.75 mgd in 2004. In 2005, production was back up to 1 mgd, and chlorides were approximately 87 mg/l. During the five years from 2001 through 2005, the City has pumped an annual average rate of approximately 1 mgd from Area III. In contrast, Area II has not been over-pumped during the same time period. Area II production generally declined from a high of 4.146 mgd in 1992 to a low of 2.525 mgd in 2000, except for an increase of approximately 0.25 mgd between 1997 and 1998. During this time, chlorides generally declined from a high of 124 mg/l in 1993 to approximately 68 mg/l in 2000, with the exception of a rise to approximately 111 mg/l in 1999. Area II production then generally increased through 2003 to approximately 3.000 mgd, where it remained in 2004 before declining to approximately 2.770 mgd in 2005. Area II chlorides were approximately 113 mg/l in 2001, 109 in 2002, 86 in 2003, 76 in 2004, and 83 in 2005. During the five years from 2001 through 2005, the City has pumped only an annual average rate of 2.86 mgd. In 1995, the City entered into a contract with the City of Cocoa requiring the City to pay for at least 1 mgd each year, whether the City actually takes the water or not (the "take-or-pay" clause). Using the Cocoa water allowed the City to reduce production from Area III without a corresponding increase in production from Area II. Water conservation measures implemented since 1998, including conservation rates, have since reduced per capita water use. In 2002, the contractual take-or-pay requirement was reduced to 0.5 mgd. After 2002, purchases of Cocoa water have amounted to 0.576, 0.712, and 0.372 mgd on an annual average basis. As a result, since at least 1990 Area II has not been required to produce at its permitted limit. It is not clear exactly what the City believes to be safe and reliable yields at this time from Areas II and III. In its PRO, the City took the position that the total reliable yield is 3.5 to 4 mgd, of which 2.25 to 2.5 mgd is attributable to the Area II Wellfield and 0.75 mgd is attributable to the Area III Wellfield. However, its consultant, Mr. Patrick Barnes, testified that the City's current reliable yields are 3 mgd from Area II and 1 or 1.1 mgd from Area III. He testified that the safe yield from Area II would be approximately 3.5 mgd. The District has not formulated an opinion as to the exact of amount of water that can be produced from the Area II and III Wellfields on a sustainable basis. However, the District believes that recent production levels, which have resulted in a stabilization of chloride concentrations, may be the most production that can be sustained from these facilities without adverse water resource impacts. That would mean approximately 4.5 mgd on an annual average basis from Areas II and III combined. It might be possible for the City to expand the reliable yield of the Area II Wellfield by constructing additional wells or through some other measures. But Brevard County’s North Brevard Wellfield, located immediately north of the City’s Area II Wellfield, utilizes the same SAS used by the Area II Wellfield, and Brevard County recently received an increased permitted allocation from the District for this facility. This would limit the City’s ability to expand the current production of water from the Area II Wellfield. Other limitations on expansion of production from Areas II and III include: the relatively high risk of contamination of the SAS from pollution sources such as underground petroleum storage tanks; the limited space available in an increasingly urbanized area for the construction of new wells; the chronic bio-fouling and encrustation of wells due to the high iron content of the SAS; and the low specific capacity of each production well. For these reasons, it is not clear at this point in time whether it is possible to sustain more water production from Areas II and III than the City has pumped in recent years. B. Area IV Application and TSR On March 6, 2001, the City of Titusville submitted its application to modify CUP 10647. Included in this application was a proposal to add a new Area IV Wellfield in northwest Brevard County to pump up to 2.75 mgd from the UFAS. The District issued a series of seven Requests for Additional Information in between April 5, 2001, and March 23, 2004. On December 15, 2004, the District issued its initial TSR for the CUP modification application. That TSR proposed to authorize the use of 2.75 mgd from the UFAS and 0.18 mgd of groundwater from the SAS from the proposed Area IV Wellfield and 3.3 mgd of groundwater from the SAS from the existing Area II and Area III Wellfields to serve a projected population of 56,565 in 2008. There was no request to extend or renew the permit, which expires February 10, 2008. Miami Corporation filed a petition challenging this TSR. On May 13, 2005, the City submitted a revised application for a separate Individual CUP for the Area IV Wellfield, rather than modifying its existing CUP 10647 to include the new wellfield, with a permit expiration of December 31, 2010. On May 25, 2005, the staff issued a revised TSR. That TSR proposed a new permit to authorize up to 2.75 mgd of groundwater from the UFAS and 0.178 mgd of groundwater from the SAS from the proposed Area IV Wellfield to serve a projected population of 59,660 in 2010. The revised TSR noted that the proposed permit expiration date for the Area II and Area III Wellfields would remain February 10, 2008. Vergie Clark filed a petition challenging the revised TSR, as did Miami Corporation. After various notices on the TSR and the revised TSR to interested persons in Brevard County, in August 2005 the District issued additional notice to interested persons in Orange, Seminole and Volusia Counties. As a result, all required public notices have been issued. On March 14, 2006, the City again revised its application, and on May 1, 2006, the District issued its second revised, and final, TSR--which is the TSR now at issue. The TSR at issue recommended that a CUP be issued to Titusville for 2.75 mgd of groundwater from the UFAS and .18 mgd of groundwater from the SAS for wetland hydration and aquifer recharge from the Area IV Wellfield on an annual average basis to serve a projected population of 63,036 in 2010. This TSR provided that the proposed permit would expire December 31, 2010. TSR at Issue Water Use Allocation The CUP recommended by the TSR would only grant the City a water allocation from the Area IV Wellfield for 2009 and 2010. The recommended CUP would allow the City to withdraw water from the Area IV Wellfield at an annual average rate of 2.75 mgd during those years for public supply. (Other Condition 4) The CUP recommended by the TSR would limit the City’s potable water allocation from the Area IV Wellfield to a maximum rate of 3.85 mgd during the four consecutive months of the dry season, which can occur during any time of the year. If 3.85 mgd is withdrawn during this four-month period, the withdrawal rate for the remaining 8 months cannot exceed 2.21 mgd. (Other Condition 8) The CUP recommended by the TSR would limit the City’s potable water allocation from the Area IV Wellfield to a maximum rate of 4.41 mgd during any single month. (Other Condition 7) The CUP recommended by the TSR would limit the City’s potable water allocation from the Area IV Wellfield to a maximum rate of 6.5 mgd during any single day during a severe drought, when the existing sources (meaning Areas II and III) cannot be used without inducing water quality degradation or exceeding permitted quantities. (Other Condition 9) The CUP recommended by the TSR would allow the City to withdraw water from the SAS extraction wells at an annual average rate of up to 0.178 mgd in 2009 and 2010 for wetland hydration and surficial aquifer recharge. (Other Condition 6) The CUP recommended by the TSR would limit the withdrawal of water from the Area II, III and IV Wellfields to a combined annual average rate of 5.79 mgd in 2009 and a combined annual average rate of 6.01 mgd in 2010. The CUP recommended by the TSR would limit the withdrawal of water from the Area II, III and IV Wellfields to a combined maximum daily rate of 8.88 mgd in 2009 and 9.0 mgd in 2010. (Other Conditions 5, 9) The CUP recommended by the TSR would reduce Titusville's combined annual average and maximum daily allocations from the Area II, III and IV Wellfields in 2009 and 2010 by an amount equivalent to the quantity of water purchased from the City of Cocoa during each year. (Other Conditions 5, 9) Other Condition 10 in the recommended by the TSR notifies the City that nonuse of the water supply allocated by the CUP for two years or more is grounds for revocation by the District's Governing Board, permanently and in whole, unless the City can prove that its nonuse was due to extreme hardship caused by factors beyond the City's control. Permit Duration The CUP recommended by the TSR would not allow the City to withdraw water from the Area IV Wellfield earlier than January 1, 2009; as indicated, it would expire on December 31, 2010. (Other Conditions 2, 4). Saline Water Intrusion The CUP recommended by the TSR contains a permit condition requiring the City to implement the proposed saline water monitoring plan by sampling and analyzing Saline Water Monitor Wells SWMW 1-6 and UFAS production wells 401, 403, 405, 407, 409, 411, 413 and 415 quarterly for water levels, chloride and total dissolved solids. (Other Condition 11) The CUP recommended by the TSR contains a permit condition authorizing the District to modify the allocation granted to the City in whole or in part or to otherwise curtail or abate the impact in the event of saline water intrusion. (Other Condition 14) The CUP recommended by the TSR contains a permit condition requiring the City to cease withdrawal from any UFAS production well, if any quarterly water sample from that well shows a chloride concentration exceeding 250 mg/l. That same condition would limit the operation of any UFAS production well with a quarterly sample exceeding 250 mg/l to six hours per day with a minimum 24 hours recovery between pumping cycles if subsequent samples contain chloride concentrations between 200 mg/l and 249 mg/l. (Other Condition 25) Environmental Impacts and Avoidance and Minimization The CUP recommended by the TSR contains a permit condition requiring the City to implement the proposed environmental monitoring plan for hydrologic and photo- monitoring at 16 wetland sites within one year of permit issuance and to establish a baseline prior to the initiation of groundwater withdrawals. That same condition requires the City to collect water level data at each wetland site either on a daily or weekly basis and report to the District every six months in District-approved, computer-accessible format. (Other Condition 12) The CUP recommended by the TSR contains a permit condition authorizing the District to revoke the permit in whole or in part or to curtail or abate impacts should unanticipated adverse impacts occur to wetlands, lakes and spring flow. (Other Condition 23) The CUP recommended by the TSR contains a permit condition authorizing the District to require the City to implement the proposed avoidance and minimization plan should unanticipated impacts occur to Wetland A4-2 (a shallow marsh near the middle of the wellfield) within 90 days of notice by the District. That same permit condition authorizes the District to require the City to submit a wetland rehydration plan for any other adversely affected wetland within 30 days of notice by the District and to implement the plan without 90 days of approval by the District. The District would require the City to implement avoidance measures before the wetlands are actually allowed to suffer adverse impacts. (Other Condition 24) Impacts to Other Existing Legal Users of Water The CUP recommended by the TSR contains a permit condition authorizing the District to require mitigation of any unanticipated interference to existing legal users of water due to withdrawals from the Area IV Wellfield. Mitigation may include installation of a new pump or motor, installation of additional drop pipe, new electrical wiring, connection with an existing water supply system, or other appropriate measures. (Other Condition 15) Water Conservation Measures and Reuse The City is implementing extensive water conservation measures. The City’s water conservation plan includes public education measures (e.g., televised public service announcements, helping to create water conservation videos and distributing them to the public, commissioning an award winning native plant mural, providing exhibits and speakers for public events), toilet and showerhead retrofits, and a water conservation based rate structure. A water conservation rate structure provides the potable water customer with an economic incentive to use less water. The most common conservation rate structure is a tiered-rate whereby the cost per gallon of water increases as the customer uses more water. While the District reviews the rate structure to evaluate whether it will achieve conservation, it does not mandate the cost per gallon of water. An audit of the City’s potable water distribution system was conducted and recent water use records were evaluated to determine if all necessary water conservation measures were in place. The audit indicated that the potable water system has small unaccounted-for water losses, approximately 6.5 percent, and relatively low residential per capita water use. The City has implemented a water conservation plan that implements rule requirements; as a result, the City has provided reasonable assurance that it is implementing all available water conservation measures that are economically, environmentally, or technologically feasible. The City cannot use reclaimed water to meet its potable water demands associated with direct human consumption and food preparation. However, reclaimed water can be used to replace that part of the City’s allocation that is associated with irrigation-type uses. The City has operated a reclaimed water reuse system since 1996. It is projected that 67 percent of the available wastewater flows will be utilized by 2010 for irrigation, with the remainder going to a wetland system during wet weather periods when irrigation demands are low. The City is using reclaimed water to the extent it is economically, environmentally and technologically feasible. In the case of public supply, the District looks to the amount of water requested for each person in a projected population in determining whether the water will be used efficiently. The metric that the District normally considers when conducting this part of the evaluation is the per capita usage. Population Projections and Per Capita Water Use As indicated, the proposed CUP would expire on December 31, 2010. Although the City and District would anticipate an application for renewal to be filed, demand for water projected beyond December 31, 2010, is not relevant to the need for the proposed CUP. In the case of public supply, projected demand for water usually is calculated by multiplying the projected population times per capita water use. Gross per capita (“GPC”) use in gallons per day (gpd) is the type of metric normally used to project demand for public supply of water. It is based on residential use and all other water uses supplied by the utility, including commercial, industrial, hotel/motel, and other type uses. That includes supply necessary to meet peak demands and emergencies. DEP requires that every public water supply system have an adequate water supply to meet peak demands for fire protection and health and safety reasons. If peak demands are not met, a major fire or other similar catastrophe could depressurize a public water system and possibly cause water quality problems. Projections of need for water in the future must take into account peak demands and emergency needs. Water used for those purposes is included in the historical average daily flows (ADF) from which historical GPC is derived. Unless there is good information to the contrary, in projecting GPC one assumes that those uses will increase roughly in proportion to the residential use. City's Projection Contending that the University of Florida Bureau of Economic and Business Research (BEBR) does not estimate or project population for municipalities, and that BEBR projections are based on historical trends that would under-project population in the City, the City used a different source and method to project population in the City's water service area on December 31, 2010. For its method, the City had Courtney Harris, its Planning Director, project the number of dwelling units that would be developed and occupied in 2011, calculating the additional people associated with each unit (based on the 2000 Census, which identified 2.32 as the average number of persons per dwelling unit in the City), and adding the resulting number to the City’s existing service area population as of 2005. The City's method yielded various results depending on when proposed developments in the City were reviewed. Ultimately, the City projected a population of 60,990 at the end of 2010. The City's method depends on the ability of its Planning Director to accurately predict the timing of new residential construction and sales, which is not easy to do (as indicated by the different results obtained by the City over time), since there are many factors affecting residential development and the real estate market. The ultimate predictions of the City's Planning Director assume that residential development will continue at an extraordinarily high pace although there already was evidence of downturn. The City's method also assumed that all new units will be sold (which, again, is contingent on market conditions) and fully occupied (although a 90 percent occupancy rate would be a more realistic.) The method also does not account for decreases in population in a number of areas in the Titusville service area (while overall population increased, mostly as a result of growth that has been occurring in a single census tract.) The City's witnesses then calculated a per capita water use rate by averaging the actual rates for the 11 years from 1995 through 2005, which resulted in projected per capita water use rate of 100.35, and a projected demand of 6.12 mgd at the end of 2010. The justification for averaging over 11 years, instead of the last five years, was that the last five years have been unusually wet, which would depress demand to some extent. However, using 11 years also increased the average water use by taking into account the higher use rates common before conservations measures, including conservation rates, went into effect (in particular, 123.75 gpd for 1995, 122.36 gpd for 1996, and 109.94 gpd for 1998.) Since 1998, and implementation of the conservation rates and other measures, water use rates have been significantly lower. While the average over the last 11 years was 100.35 gpd, the average over the last five years (from 2001- 2005) was just 92.15 gpd. Averaged since 1998, the City's water use rate has been 93.34 gpd. While wetter-than-normal conditions would be expected to depress water use to some extent due primarily to decreased lawn irrigation, many of the City's water customers have private irrigation wells for this purpose. Besides, Mr. Peterson, the City's Water Resources Manager, testified that not many of the City's water customers use potable water for lawn irrigation due to the new conservation rates. Petitioners' Projection Miami Corporation's population expert, Dr. Stanley Smith, is the Director of BEBR. Dr. Smith projected the population for the City's service area by first developing an estimate of the population of the water service area in 1990 and 2000 using block and block group data, and then using those estimates to create estimates from 2001-2005. Dr. Smith then projected population in the City's water service area using a methodology similar to what BEBR uses for county projections. Dr. Smith's methodology used three extrapolation techniques. He did not use a fourth technique, often used at BEBR, called shift-share, because he believed that, given Titusville's pattern of growth, using shift-share might produce projections that were too low. In developing his final projections, Dr. Smith also excluded the data from 1990 to 2000 because growth during that period was so slow that he felt that its inclusion might result in projections that were too low. Dr. Smith's approach varied slightly from the typical BEBR methodology in order to account for the fact that the City's growth has been faster since 2000. Dr. Smith applied an adjustment factor based on an assumption also used by the City's expert that 97.3 percent of the projected population within the City's water service area in 2010 would be served by the City. Using his method, Dr. Smith projected the population of the Titusville water service area to be 53,209 on December 31, 2010. Based on recent population estimates, Dr. Smith believes that, if anything, his projections are too high. It was Dr. Smith's opinion from the data that the annual increases for Titusville and the Titusville water service area peaked in 2003 and that they had been declining since that time. That was especially true of 2006, when the increase was the smallest that it had been for many years. Petitioners' expert, Mr. Drake, calculated a per capita water use rate by averaging the actual rates for the most recent five years (2002-2006), which resulted in a per capita water use rate of 89.08 gpd, and a projected demand of 4.74 mgd at the end of 2010. He also calculated a per capita water use rate for 2006, which came to 88.65 gpd, which would give a slightly lower projected demand of 4.72 mgd. Ultimate Finding of Projected Water Demand Based on all the evidence, it is found that Dr. Smith's projection of the population that will use City water on December 31, 2010, is more reasonable than the City's projections. The City and District contend that, regardless of the calculated per capita water use rate, it is appropriate to base the City's allocation on a rate of 100.35 gpd because 90 to 100 gpd is very conservative per capita water use rate for a public water supply utility. However, the allocation should be based on the best estimate of actual demand, not a general rate commonly assumed for water utilities, even if conservative. The City and District also contend that it is appropriate to base the City's allocation on a higher use rate because the climatic conditions experienced in the City over what they considered to be the most recent five years (2001- 2005) have been average-to-wet. More rainfall generally means less water use, and vice-versa, but the greater weight of the evidence proved that the City's demand for water has not varied much due to climatic conditions in recent years (after implementation of conservation measures, including conservation rates.) (City Exhibit 19, which purported to demonstrate the contrary, was proven to be inaccurate in that it showed significantly more water use during certain drier years than actually occurred.) However, in 2000--which was after the implementation of conservation rates and also the City's driest year on record (in approximately 75 years)--the water use rate was approximately 97.5 gallons per person per day. An average of the last eight years (1999-2006), which would include all years clearly responsive to the conservation rates as well as the driest year on record, would result in a per capita water use rate of approximately 92.8 gpd, and a projected demand of approximately 4.94 mgd by December 31, 2010. The District argues in its PRO that, because a CUP water allocation is a legal maximum, it would be inappropriate to base the City's water allocation on demand during a wet or even an average year (which, it says, would set the permittee up to violate its permit requirements 50 percent of the time). If, instead, the City's water allocation were based on demand during 2000, the driest year on record, projected demand would be approximately 5.2 mgd on December 31, 2010. Those calculated water allocations--i.e., either the 4.94 mgd or the 5.2 mgd--would then be compared to the probable safe and reliable yield of 4.5 mgd from Areas II and III to determine the deficit on an annual average basis. Allowing a reasonable margin of error for the uncertainties of the predictions involved, a reasonable maximum annual average allocation for the proposed Area IV Wellfield would be 0.75 mgd. Mr. Jenkins suggested in rebuttal that, if the need for water is less than that set out in the proposed CUP in the TSR at issue, a CUP should nonetheless be issued but with lower water allocations. While the evidence supports a reduction of the annual average limit from 2.75 mgd to 0.75 mgd, there was insufficient evidence to show how the other water allocation limits in the proposed CUP should be changed. For the past 12 years, the City of Titusville has been able to purchase water under a contract with the City of Cocoa to meet all of its demands, including any peak or emergency water demands. Under the take-or-pay provision in the contract currently in effect, the City must pay for 0.5 mgd and presumably would take and use at least that amount so long as the contract remains in effect. This would reduce the City's projected water supply deficit through the end of 2010, and the City could rely on the Cocoa contract to cover any additional demand through the end of 2010 without Area IV. However, under the contract, the City can give notice on or before April 1 of the year in which it intends to terminate the contract effective October 1 of the same year. If a CUP for Area IV is issued, the City could terminate the current contract effective as early as October 1, 2008. It also is possible that the contract could be negotiated so that its termination would coincide with the time when the Area IV Wellfield becomes operational if not near October 1 of the year. As indicated, even if the contract remains in place, to the extent that the City receives water from the City of Cocoa for potable use during either 2009 or 2010, the allocations under the proposed TSR will be reduced an amount equivalent to the quantity provided to the City by Cocoa in that year. Finally, as indicated, the existing CUP for Areas II and III is set to expire in February 2008. Although it is anticipated that the City will apply to renew the existing CUP for Areas II and III, and that the District will approve a renewal at some level, it is not clear how much production will be approved for Areas II and III for the years 2009 and 2010. Meanwhile, the CUP proposed for Area IV provides that the combined annual groundwater withdrawals for public supply for the Areas II, III, and IV may not exceed 5.79 mgd for 2009 and 6.01 mgd in 2010. Based on the findings in this case, those figures should be reduced to no more than 5.2 mgd, and it must be anticipated that a similar condition would be placed on any renewal of the existing CUP for Areas II and III as well. Site Investigation At the time the City decided to apply for a CUP for Area IV, it was known that the UFAS in much of Brevard County was not suitable as a source of potable water supply, but there was believed to be a tongue of the UFAS in the northwest corner of the County and extending towards the southeast, and narrowing in that direction, that might be suitable for that purpose, particularly in the upper part of the aquifer. Because there was insufficient information to adequately evaluate the whether proposed Area IV, which was located along the Florida East Coast Railway (FEC) Right-of-Way (ROW), could be used for that purpose, the City’s consultant, Barnes, Ferland and Associates (BFA), designed a drilling and testing program to collect site-specific information in order to characterize the groundwater quality, identify the thickness of the freshwater zone in the UFAS, and determine hydraulic parameters for the groundwater system. In addition, DRMP conducted an environmental assessment of the Area IV Wellfield and surrounding property. The drilling and testing program designed by BFA for the Area IV Wellfield was similar to other hydrogeologic investigations conducted in the region with respect to wellfields operated by the City of Edgewater, the City of New Smyrna Beach, the City of Ormond Beach, the Orlando Utilities Commission and Orange County. The drilling and testing program for the Area IV Wellfield included Time-Domain Electromagnetic Mapping ("TDEM") performed by SDII Global, a consultant retained by the District. TDEM is not typically used for the hydrogeologic investigation of a new wellfield. The TDEM technique involves estimating the depth to the 250 mg/l and 5,000 mg/l chloride concentration in the groundwater system using electrical resistivity probes. The technique was applied at four locations along the FEC Right-of- Way. In addition to the TDEM study, BFA installed three test production wells along the FEC ROW, collected lithologic samples with depth, performed borehole aquifer performance and step drawdown tests at two test sites and recorded water quality with depth through grab and packer samples. The northernmost test production well was Test Site 1, which corresponds to Area IV production well 401. The middle test production well was Test Site 3, which corresponds to either Area IV Well 412 or Area IV Well 413. The southernmost test production well was Test Site 2, which is located approximately 1.5 miles south of the southernmost Area IV production well. Test Sites 1 and 2 were constructed first and Test Site 3 was drilled later because of unfavorable water quality conditions encountered at Test Site 2. Test Site 1 is located on the FEC ROW approximately 430 feet southeast of the Volusia-Brevard County line. At Test Site 1, BFA installed a test-production well (UF-1D), a UFAS monitor well (UF-1S), and a SAS monitor well (SA-1) in 2001. In 2005 BFA installed two additional SAS monitor wells (MW-1 and RW-1) near Test Site 1. The test production well was drilled to a depth of 500 feet below land surface and then back-plugged to a depth of 250 feet below land surface and cased to a depth of 105-110 feet below land surface. Test Site 2 is located on the FEC ROW approximately 2.8 miles southeast of the Volusia-Brevard County line. At Test Site 2, BFA installed a single UFAS Monitor Well (UF-2S). The monitor well was drilled to a total depth of 210-220 feet below land surface. Test Site 3 is located on the FEC ROW approximately 1.4 miles southeast of the Brevard-Volusia County line. At Test Site 3, BFA installed a test production well (UF-3D), a UFAS monitor well (UF-3S), and a SAS monitor well (SA-3). The test production well was drilled to a depth of 500 feet below land surface and then back-plugged to a depth of 210 below land surface.. Since Test Site 3 is either Area IV Well 412 or 413, and assuming production well 415 will be located 1,200 feet southeast of Test Site 3, this means that Test Site 2 is located at least one mile southeast of the southernmost Area IV production well. Test Sites 4 and 6 are located approximately three miles southeast of Brevard-Volusia County line. SAS test production wells were constructed at both sites to a total depth of about 20-30 feet below land surface. The site-specific hydrogeologic data collected by BFA as part of the drilling and testing program verified the groundwater basin and flow direction shown in Figure 15 of City Exhibit 523. DRMP’s environmental assessment of the Area IV Wellfield spanned the period from 2002 through 2006. In Spring 2002, DRMP evaluated areas within the predicted 0.2 foot drawdown contour by assessing wetland vegetation, photographing wetlands, noting wetland hydrologic conditions, investigating soil condition and wildlife utilization and evaluating surrounding land uses and natural communities. In Fall 2002, DRMP evaluated potential monitoring sites both on and off Miami Corporation's property by assessing wetland vegetation composition and hydrologic conditions, investigating soil conditions and wildlife utilization, evaluating surrounding land use and natural communities and locating suitable control sites. In Fall 2003, DRMP evaluated potential wetland monitoring sites near the southernmost Area IV production wells by assessing wetland vegetation composition and hydrologic conditions, investigating soil conditions and evaluating surrounding land uses and natural communities. In Spring 2005, DRMP assessed wetlands surrounding the Area IV Wellfield by evaluating wetland vegetation composition and hydrologic conditions, photographing wetlands, investigating soil conditions, evaluating surrounding land use and natural communities and collecting GPS points. In Fall 2005, DRMP investigated the Clark property by evaluating wetland vegetation and hydrologic conditions, photographing wetlands, investigating soil conditions and wildlife utilization and evaluating surrounding land uses and natural communities. In Spring 2006, DRMP developed a revised environmental monitoring plan and avoidance and minimization plan based on the new SDI MODFLOW Model by locating the final wetlands monitoring sites, developing the hydrologic and vegetative monitoring protocol, establishing the scope of the baseline study, reviewing the preliminary pipeline routing, construction and discharge inlet structures and preparing and submitting plan documents to the District. DRMP evaluated the occurrence of listed animal and plant species in the vicinity of the Area IV Wellfield as part of its environmental assessment. DRMP reviewed the Natural Areas Inventory for the Area IV Wellfield site, which identifies occurrences of listed species within a designated area. Additionally, DRMP made note of animal and plant species during the site visits in 2002, 2003, 2005, and 2006. DRMP evaluated the Farmton Mitigation Bank as part of its environmental assessment. DRMP reviewed the permit files for the Farmton Mitigation Banks, including the annual environmental monitoring reports prepared by Miami’s consultants. In 2005, DRMP conducted a field assessment of the Clark property including a thorough investigation of the fish pond, which Petitioners claim was adversely impacted during one or more of the APTs conducted by the City at the Area IV Wellfield. It was not necessary for the City’s environmental consultants to visit each and every wetland in the vicinity of the proposed Area IV Wellfield. Typically, only representative wetland sites are visited during the environmental assessment process. The scope of the City's hydrologic and environmental investigation of the Area IV Wellfield was adequate and consistent with industry standards and the District protocol for testing aquifers and characterizing aquifer performance and groundwater quality at the site. Nonetheless, Petitioners contend that there were serious deficiencies in the investigation's implementation and that additional investigation should have been performed. Hydrostratigraphy The SAS at the Area IV Wellfield is 40-to-50 feet deep and is composed primarily of unconsolidated sand, shell and silt. The intermediate confining unit (ICU) at the Area IV Wellfield consists of the Hawthorne Group and ranges in thickness from 40 to 60 feet. The top of the ICU is located 40- 50 feet below land surface and the bottom of the ICU is located 100 feet below land surface. This unit is composed of varying amounts of sand, shell, silt, indurated sandstone, clay, and some limestone. It tends to restrict the movement of water from the SAS to the UFAS. The UFAS at the Area IV Wellfield is a fairly homogenous limestone unit, which starts approximately 100 feet below land surface and extends to about 450 feet below land surface or 425 feet below mean sea level. It consists of the Ocala Group and grades into the upper portion of the Avon Park Formation. The middle confining unit (MCU) at the Area IV Wellfield starts at approximately 450 feet below land surface or 425 feet below mean sea level and ends approximately 1,000 feet below land surface. It comprises a denser, fine-grained dolomitic limestone within the Avon Park Formation. The MCU restricts the movement of water between the UFAS and LFAS. The location of the MCU at the Area IV Wellfield was determined by examining cuttings and video logs collected during drilling performed at Test Sites 1 and 3 and by measuring various properties of the aquifer with down-hole geophysical techniques. The MCU can be distinguished from the UFAS by the presence of both dolomite and limestone. The lithologic log for Test Site 1 indicates the presence of gray/tan limestone between 450 and 460 feet below land surface and light/gray limestone and dolomitic limestone between 460 and 470 feet below land surface. The lithologic log for Test Site 3 indicates the presence of tan dolomitic limestone between 450 and 460 feet below land surface and tan limestone and dolomitic limestone between 460 and 470 feet below land surface. After examining the video log for Test Site 1, Petitioners’ expert, Dr. Thomas Missimer, noted a “lithologic change” at 477 feet below land surface. Other characteristics of the MCU are a lower resistivity and a sharp decrease in flow. The data collected at Test Site 1 shows a reduction in resistivity at approximately 470 feet below land surface. The flow meter log for Test Site 1 exhibits a decrease in flow at approximately 450 feet below land surface. Petitioners’ experts, Thomas Missimer, Alge Merry, and Bruce Lafrenz contend that the top of the MCU at the Area IV Wellfield is located deeper than 450 feet below land surface or 425 feet below mean sea level. This contention is based on regional reports, the geophysical logs reported by BFA, and one of the packer tests conducted at the bottom of the test wells that showed a pumping rate of 85 gpm. The greater weight of evidence indicates the top of the MCU at the Area IV Wellfield starts at the elevation identified by BFA. The regional reports are not based on data collected from the immediate vicinity of the Area IV Wellfield. Additionally, the BFA's professional geologists who determined the top of the MCU included Joel Kimrey, who was the former head of the local USGS office, and had more experience with the hydrogeology of the MCU in Brevard and Volusia than any of the Petitioners’ geologic experts. Also, the BFA geologists had access to the drill cuttings, which were unavailable to the Petitioners’ experts when they made their determination. Finally, the pumping rate recorded during the packer test could be explained by an area of higher permeability within the MCU. More likely, the packer may have been partially open to the bottom of the UFAS. The Lower Floridan Aquifer System (LFAS) starts at about 1,000 feet below land surface and ends approximately 2,300 feet below land surface. Head Difference Data Head refers to the pressure within an aquifer. In an unconfined aquifer, it is the water table. In a confined or semi-confined aquifer, it is the level to which water would rise in a well penetrating into the aquifer. Head difference refers to the numerical difference between two water levels either in different aquifer at the same location or different locations in the same aquifer. In the context of the Area IV Wellfield, static head difference is the difference between the elevation of the water table in the SAS and the elevation of the potentiometric surface of the UFAS under non-pumping conditions at the same location. The static head difference reflects the degree of confinement in the ICU. If the static head difference between the SAS and UFAS is a large number, this indicates a high degree of confinement between the two systems. BFA took static head measurements at SAS and UFAS monitor wells located at Test Sites 1, 2 and 3 in January 2004, April 2004, and July 2006 and calculated the head difference based on those measurements. District expert, Richard Burklew, was present when the measurements were taken in April 2004 and July 2006 and verified the readings made by the City’s consultants. During all three sampling events a downward head gradient was noted at each site, which means the water table had a higher elevation than the potentiometric surface of the UFAS. In January 2004, the measured head difference at Test Sites 1, 2 and 3 were 6.2 feet, 5.5 feet and 5.9 feet, respectively. In April 2004, the measured head difference at Test Sites 1 and 3 were 8.1 feet and 8.1 feet, respectively. Finally, in July 2006, the measured head difference at Test Sites 1, 2 and 3 were 8.6 feet, 6.6 feet and 9.3 feet, respectively. The average of those observed head differences was 7.46 feet. At the time the head difference measurements were taken in July 2006, the region had experienced a rainfall deficit of 17 inches over the prior 12 months. Petitioners contend that the rainfall deficit may have skewed that head difference observation. However, according to the District’s expert, Richard Burklew, this would not necessarily have affected the head difference measurements because the hydrologic system would seek equilibrium, and the head difference would be the same. BFA collected static head difference measurements from Test Sites 1, 2 and 3 during both wet and dry seasons. The measurements do not show significant differences between seasons. Head difference data collected from hundreds of other Florida locations also do not show significant differences between seasons. This suggests that static head difference remains fairly constant at the Area IV Wellfield year round. Water level measurements taken by the City’s consultants from the wells on Clark’s property and reported in City Exhibit 52 do not determine static head difference between the SAS and UFAS because the exact construction of the wells was unknown, the completion depth of certain wells was unknown, the operational history of the wells was unknown, and the putative SAS well was located several hundred feet away from the UFAS well. For example, the depth of one of the wells is reported as 57 feet, which could easily be located in the ICU. If that is the case, then the head difference measured by comparing to the water level in this well would only be the head differential between the ICU and the UFAS. Finally, the Clark property is located in a more elevated region than Test Sites 1, 2, and 3, which means the water table will be lower and the head difference will be less than at the Area IV Wellfield. Water level measurements reported in the driller’s completion log for Wells 4175, 4176, 4177, and 5230 on Miami Corporation’s property do not determine static head difference between the SAS and UFAS because critical information concerning the construction of these wells is unknown. Additionally, the wells are much shallower than test production wells at Test Sites 1, 2 and 3. The water level measurements reported in the driller’s completion log for Wells 4175, 4176, 4177, and 5230 are not necessarily inconsistent with head difference measurements collected by BFA at Test Sites 1, 2 and 3. The head differences at these four well sites could be 6, 4, 7, and 6 feet, respectively, depending how the water measurements were made. Also, the measurements made by a driller could not be expected to be as accurate as measurements made by trained hydrologists. Further, if the soils in the vicinity of Well 4177 indicated a depth to water table of 5 feet below land surface, that would not necessarily be inconsistent with the head difference measurements collected by BFA at Test Sites 1, 2 and 3. Depth to Water Table The depth to water table is defined as the difference between the land surface elevation and the head value in the SAS. The water table in the Area IV Wellfield area is consistently close to land surface and often above land surface. The construction of numerous above-grade forest roads and roadside ditches on the property surrounding the Area IV Wellfield has had the effect of impounding surface water and raising the water table near land surface. The Area IV Wellfield and vicinity have a variety of soil types. The predominant wetland soil type is Samsula Muck, which is classified as a very poorly drained soil with a water table either at or above land surface. The predominant upland soil type is Myakka Fine Sand, which is characterized by a water table within a foot of land surface during four months of the year and within 40 inches of land surface during remainder of the year. The average depth to water table at the Area IV Wellfield is approximately 1 foot based on soil types. SAS levels at the three Farmton Mitigation Banks were measured at piezometers installed by Miami Corporation’s consultants from 2001 through 2005. This data confirms the water table at the Area IV Wellfield is consistently close to land surface and frequently above land surface. It indicates the depth to water table is typically less than 3 feet and in many cases within a foot or two. Also, it does not matter whether any of the piezometers were located near wetlands because they show seasonal variation in water levels, where the water table changes from slightly above land surface to below land surface over the course of a year. A water table depth of 6-14 feet below land surface is not realistic at the Area IV Wellfield based on soil conditions and vegetation communities. Such a depth to water would be indicative of a landscape composed primarily of xeric scrub communities with few, if any wetlands. These types of communities do not exist near the Area IV Wellfield. Aquifer Performance Tests The flow of water through an aquifer is determined by three primary hydraulic coefficients or parameters: transmissivity; storage; and leakance. An aquifer performance test (APT) is a pumping test where water is removed from the well at a set rate for a set period of time and drawdown is measured in the well and in neighboring monitor wells to calculate the hydraulic properties of the hydrologic formation. The main hydraulic properties determined through an APT are transmissivity, leakance, and storativity. These properties are used to characterize the water production capabilities of the hydrologic formations. These properties are also used in groundwater modeling to project impacts for longer periods of time and larger distances. Aquifer parameters can be determined from an aquifer performance test using analytical "curve-matching" techniques or a groundwater flow model such as MODFLOW. Curve-matching techniques involve the creation of a curve through measurement of drawdown and the matching of that curve to standard curves derived using analytical equations. Hydraulic conductivity or “K” is the term used to describe the ability of a hydrogeologic unit to conduct fluid flow. It is usually expressed in terms of horizontal hydraulic conductivity or “Kx” and “Ky” and vertical hydraulic conductivity or “Kz.” Transmissivity is the term used to describe the rate of movement of water for a given thickness of a hydrogeologic unit. It is the hydraulic conductivity of an aquifer times its thickness. Storativity is the term used to describe the amount of water that is released from any aquifer for a given unit change in head, or the compressability of the aquifer system. This value can normally be determined during a 4-5 day aquifer performance test. Specific yield is the term used to describe the long- term capacity of an aquifer to store water. This value cannot normally be determined during a 4-5 day aquifer performance test. Leakance is the term used to describe the vertical movement of water from above or below a given unit in response to changes in head or pumpage. APTs are standard practice for evaluating the suitability of a new area for development as a wellfield. Three APTs were conducted at Test Sites 1 and 3. No aquifer performance tests were conducted at Test Site 2. Petitioners question whether the APTs for the Area IV Wellfield were conducted by BFA in accordance with the applicable standard of care in the hydrogeologic profession. The District’s expert, Richard Burklew, believes the three APTs conducted at Test Sites 1 and 3 were adequate for purposes of determining appropriate aquifer parameters. Two APTs were conducted by BFA at Test Site 1. The first test was conducted on January 30-31, 2001, when Well UF-1D was pumped at about 700 gpm or approximately 1 mgd for 44-48 hours, and Wells UF-1S and SA-1 were used as monitor wells. The second test was conducted on April 8-12, 2003, when Well UF-1D was pumped at about 700 gpm or approximately 1 mgd for 96 hours, and Wells UF-1S and SA-1 were used as monitor wells. Using several analytical curve-matching techniques, BFA calculated a transmissivity of 7,300 ft2/day and a storativity of about 0.00036 on the basis of the 2001 APT at Test Site 1. They were unable to calculate a leakance value because the drawdown data did not reasonably fit the curve- matching techniques. For that reason, BFA performed another APT at Test Site 1 in 2003. Using several analytical curve-matching techniques, BFA calculated a transmissivity of 7,300 ft2/day, a storativity of 0.00045, and a leakance of 0.00029 day-1 on the basis of the 2003 APT at Test Site 1. One APT was conducted by BFA at Test Site 3 on April 10-13, 2001. Well UF-3D was pumped at about 700 gpm or approximately 1 mgd for 70 hours, and Wells UF-3S and SA-3 were used as monitor wells. Using several analytical curve-matching techniques, BFA calculated a transmissivity of 7,450 ft2/day, a storativity of 0.0002, and a leakance of 0.00026 on the basis of the 2001 APT at Test Site 3. However, because of problems with the test, leakance was not considered a good match for the analytical techniques. Leakance values determined by BFA from the APTs conducted at Test Sites 1 and 3 were based on the application of analytical curve-matching techniques. The leakance values determined through the conventional type curve-matching techniques employed by BFA are typically higher than the actual leakance values. They are also inherently limited because they assume the calculated leakance is due entirely to the ICU rather than a combination of the ICU and MCU as is the case at the Area IV Wellfield. The analytical techniques employed by BFA were unable to calculate separate leakance values for the ICU and the MCU. The best way to determine leakance values for each of these confining units was to use a MODFLOW model and observed head difference data. This was done by the City’s consultant, SDI, and is described in greater detail, infra. In January 2004, several APTs were conducted using two SAS wells referred to as Test Sites 4 and 6. These test sites are located more than 3 miles from the Clark property. Constant rate and variable rate APTs were conducted at both sites. During the constant rate tests, 230 gpm or about 0.33 mgd was pumped from the SAS well. Using several analytical curve-matching techniques, BFA calculated a transmissivity of 2,500 ft2/day for the surficial aquifer at those locations. Water Quality Data Consistent with the general understanding of the freshwater groundwater tongue extending from Volusia into Brevard County, the TDEM performed by SDII Global indicated that the depths to the 250 mg/l and 5,000 mg/l chloride concentrations decrease as one proceeds south along the FEC ROW. For example, the depths to the 250 mg/l and 5,000 mg/l chloride concentrations were 442 feet and 542 feet, respectively, at the northernmost test site, which is somewhat north of the City’s Test Site 1. The depth to the 250 mg/l and 5,000 mg/l chloride concentrations were 406 feet and 506 feet, respectively, at the southernmost test site, which is somewhat south of the City’s Test Site 2. Sixteen water quality grab samples were collected every 20-30 feet as the test production well at Test Site 1 was drilled, beginning at 120 feet below land surface and ending at 500 feet below land surface. This type of sampling is referred to as drill-stem testing. The chloride concentrations in the samples collected from 120 feet and 480 feet below land surface were 59 mg/l and 879 mg/l, respectively. The chloride concentrations in these samples did not exceed 250 mg/l until a depth of 460 feet below land surface was reached. Six water quality grab samples (drill-stem tests) were collected every 20-30 feet as the test production well at Test Site 2 was drilled, beginning 120 feet below land surface and ending 210 feet below land surface. The chloride concentrations in the samples collected from 120 feet and 210 feet below land surface were 124 mg/l and 845 mg/l, respectively. The chloride concentrations in these samples did not exceed 250 mg/l until a depth of 180 feet below land surface. Fourteen water quality grab samples (drill-stem tests), were collected every 20-30 feet as the test production well at Test Site 3 was drilled, beginning at 120 feet below land surface and ending at 500 feet below land surface. The chloride concentrations in the samples collected from 120 feet and 500 feet below land surface were 45 mg/l and 90 mg/l, respectively. The chloride concentrations in these samples never exceeded 90 mg/l. A packer test is a procedure used to isolate a particular well interval for testing. It is performed using an inflatable packer on the drill stem, which is placed at the interval to be blocked. The packer is inflated with water or air to isolate the interval to be sampled. A packer test can be used to collect water samples for analysis. Several water quality grab samples were collected in packer tests at specific depth intervals at Test Site 1. At the interval of 331-355 feet below land surface one sample was taken with a chloride concentration of 672 mg/l. At the interval of 331-400 feet below land surface, one sample was taken with a chloride concentration of 882 mg/l. Finally, at the interval of 442-500 feet below land surface two samples were taken with chloride concentrations of 2,366 mg/l and 2,2712 mg/l. Several water quality grab samples were collected in packer tests at specific depth intervals at Test Site 3At the interval of 270-295 feet below land surface, two samples were taken with chloride concentrations of 74 mg/l and 450 mg/l. At the interval of 340-400 feet below land surface, two samples were taken with chloride concentrations of 64 mg/l and 134 mg/l. Finally, at the interval of 445-500 feet below land surface, two samples were taken with chloride concentrations of 1,458 mg/l and 2,010 mg/l. No packer test samples were collected at Test Site 2, where it was clear that water quality was too poor to be used as a fresh groundwater source. The packer test samples collected at Test Sites 1 and 3 were collected using a higher pumping rate than typically recommended by the DEP and the United States Environmental Protection Agency (EPA). Consequently, the chloride concentrations in these samples are probably higher than the chloride concentrations found in the undisturbed groundwater at those depths. Since the packer sits on top of the borehole and restricts flow from above, it generally is reasonable to assume that a packer test draws more water from below than from above the packer. However, if transmissivity is significantly greater just above the packer, it is possible that more water could enter the packer from above. Seven water quality grab samples were collected every 12 hours during the 2001 APT at Test Site 1. The chloride concentrations in the first and last grab sample were 59 mg/l and 58 mg/l, respectively. Seven water quality grab samples were collected every 12 hours during the 2001 APT at Test Site 3. The chloride concentrations in the first and last grab samples were 19 mg/l and 52 mg/l, respectively. Nine water quality grab samples were collected every 12 hours during the 2003 aquifer performance test at Test Site The field-measured chloride concentrations in the first and last grab samples were 56 mg/l and 55 mg/l, respectively. The laboratory measured chloride concentrations in the first and last grab samples were 66 mg/l and 74 mg/l, respectively. The average chloride concentration for the water samples collected during the three APTs at Test Sites 1 and 2 was about 50 mg/l. Water is composed of positively charged analytes (cations) and negatively charged analytes (anions). When cations predominate over anions, the water is said to have a positive charge balance; when anions predominate over cations, the water is said to have a negative charge balance. Theoretically, a sample of water taken from the groundwater system should have a charge balance of zero. However, in real life this does not occur because every sample contains some small trace elements that affect its charge balance. Therefore, in the field of hydrogeology, a positive or negative charge balance of 10 percent or less is accepted as a reasonable charge balance error, and this standard has been incorporated in the permit conditions recommended by the District for the City’s permit. With one exception, all the water quality samples collected by BFA from Test Sites 1-3 had an acceptable charge balance. The one exception was a sample collected from the packer interval of 270-295 feet below land surface at Test Site 3 with a chloride concentration of 74 mg/l. This sample has a positive charge balance of 32.30 percent. The sample collected from the packer interval of 270- 295 feet below land surface at Test Site 3 has an overabundance of cations probably caused by grouting and cementing of the packer prior to taking the sample. Since chloride is an anion and not a cation, any error associated with this sample would not effect the validity of the 74 mg/l chloride concentration measured in this sample. This conclusion is also supported by the fact that two samples were collected from the same well at a packer interval of 340-400 feet below land surface with acceptable charge balances and they contained chloride concentrations of 64 mg/l and 134 mg/l. The District’s experts, Richard Burklew and David Toth, believe the 450 mg/l chloride concentration measured in a sample taken from the packer interval of 270-295 feet below land surface at Test Site 3 is a faulty measurement and should be discarded as an outlier. Dr. Toth testified that the sodium to chloride ratio indicates there was a problem with this measurement, which would call into question the reported chloride value. In 2004 and 2005, the City collected SAS water quality samples from Test Sites 4 and 6 and Monitor Wells MW-1 and RW-1 near Test Site 1. The samples were analyzed for all applicable water quality standards, which might preclude use of water from the SAS extraction wells to directly augment wetlands. The analyses found that the SAS water quality near the proposed extraction wells was very similar to the SAS water quality near the Area IV production wells and that water could be applied to the wetlands without any adverse water quality consequences. Area IV UFAS Flow Patterns and Basin Boundaries Although the United States Geologic Survey (USGS) potentiometric surface maps do not show any data points in the vicinity of the proposed Area IV Wellfield, and they are not sufficient by themselves to formulate opinions regarding the future operation or impacts of the proposed wellfield, Petitioners contend that these potentiometric surface maps demonstrate that the freshwater found in the UFAS at the Area IV Wellfield is due to local freshwater recharge only and not freshwater flow from the northwest. They point to a regional report indicating that there is a groundwater basin divide just north of the Area IV Wellfield. This report is based on a 1980 USGS potentiometric surface map. However, another regional report indicates that the groundwater basin divide occurs south of the Area IV Wellfield. This report is likely based on a 1998 USGS potentiometric surface map. Because of the lack of data points in rural northwest Brevard County, the City did not rely on any groundwater basin divide maps, but rather collected site specific information regarding the proposed Area IV Wellfield. The District’s expert and the Petitioners’ own expert (the sponsor of Petitioners' potentiometric surface map exhibits) noted several errors in the flow direction arrows added by Petitioners to the maps. In addition, after reviewing the potentiometric surface maps presented by Petitioners, the District’s expert concluded that, in addition to local freshwater recharge, the predominant flow into the vicinity of the Area IV Wellfield is generally from the northwest and southwest. To confirm his opinion, the District’s expert examined the head difference data collected in July 2006. At well UF-1S, the UFAS observation well at site 1, the elevation in the well was 16.27 NGVD. At site 3, which is southeast of site 1, the elevation in the UFAS observation well was 15.68 NGVD. At site 2, which is southeast of site 3, the elevation in the UFAS well was 13.87 NGVD. Since water generally flows from the highest to lowest head measurements, these measurements indicated that water would have been flowing from the northwest to the southeast in the vicinity of Area IV. However, the potentiometric surface can change both seasonally and yearly; likewise, the basin boundaries may also change. SAS and UFAS Drawdown Predicting drawdown in the SAS and UFAS in the vicinity of the proposed Area IV Wellfield is important to several permitting criteria, including interference with existing legal uses and impacts on wetlands, both of which relate to the public interest. During the permit application review process, the City submitted a succession of models to provide reasonable assurance that the proposed Area IV Wellfield would not result in unacceptable drawdown. Initially, BFA prepared and submitted groundwater flow simulations of the Area IV Wellfield prepared using an analytical model known as the “Multi-Layer/SURFDOWN Model.” Although the District initially accepted the submission as providing reasonable assurance to support the District's initial TSR, Miami Corporation petitioned and criticized the City's model as not actually providing reasonable assurance, both because of its predicted SAS drawdown and because it was an analytical model (which can only represent simple conditions in the environment, assumes homogenous conditions and simple boundary conditions, and provides only a model-wide solution of the governing equation). By comparison, a numerical model allows for complex representation of conditions in the environment, heterogeneous conditions and complex boundary conditions, and cell-by-cell iterative solutions of the governing equation that are typically performed by a computer. Over the past 10 to 15 years, a numerical model called MODFLOW has become the standard in groundwater modeling throughout the United States and much of the world. All of the Florida water management districts utilize MODFLOW or are familiar with it, so it is a model of choice today for groundwater flow modeling. Despite Miami Corporation's petition, the City and the District maintained that reasonable assurance had been given that operation of Area IV would not result in unacceptable drawdown. Miami Corporation's petition was scheduled for a final hearing in June 2005 that was continued until September 2005 after the first revised TSR was issued in May 2005. The final hearing was continued again until February 2006 to allow discovery and hearing preparation by Vergie Clark, who filed her petition in July 2005. As the case proceeded towards a February 2006 final hearing on the pending petitions, the City eventually made what actually was its second attempt to develop a calibrated MODFLOW model of the Area IV Wellfield. Unbeknownst to the District, BFA already had attempted to develop a MODFLOW Model of the Area IV Wellfield in 2004, with the assistance of Waterloo Hydrogeologic, Inc. (WHI) (which later was retained as Petitioners’ consultant in this case in a reverse of the Hartman client switch). When BFA ended its efforts with WHI, their efforts to calibrate a MODFLOW model for Area IV that would predict acceptable drawdown was unsuccessful, and none of those modeling efforts were submitted or disclosed to the District. In the fall of 2005, the City turned to another consultant, SDI, to attempt to develop a calibrated MODFLOW Model of the Area IV Wellfield. SDI initially prepared a so- called MODFLOW model equivalent of the Multi-layer/SURFDOWN Model prepared by BFA. It was presented to District staff at a meeting held in January 2006 for the purpose of demonstrating to District staff that the MODFLOW model equivalent of the Multi- layer/SURFDOWN Model generated results for the Area IV Wellfield that were not very different from the results obtained by BFA using their Multi-layer/SURFDOWN Model. Petitioners criticized several weaknesses in the MODFLOW equivalent model and maintained that the modeling efforts to date did not give reasonable assurance of no unacceptable SAS drawdown. By this time, the District had decided to retain Dr. Peter Huyakorn, a renowned modeling expert. Based on his recommendations, the District required the City to produce a calibrated MODFLOW model of Area IV (as well as numerical solute transport modeling, which will be discussed below). The scheduled final hearing was continued until September 2006 to allow time for this work to be completed, discovered, and evaluated. After the continuance, the City had SDI prepare a calibrated MODFLOW model to predict the drawdown that would result from operation of Area IV. SDI produced such a model in March 2006. This model predicted less drawdown. Specifically, a steady-state simulation of a 2.75 mgd withdrawal from the proposed 15 UFAS production wells and a 0.18 mgd withdrawal from the four proposed SAS extraction/wetland augmentation wells predicted the maximum drawdown of the surficial aquifer to be less than 0.5 foot (which, as discussed infra, would be acceptable). (UFAS drawdown, which is not an issue, was predicted to be an acceptable 12 feet.) But Petitioners questioned the validity of the model for several reasons, including its suspect calibration. Dr. Huyakorn also had questions concerning the calibration of SDI's March 2006 MODFLOW model, but subsequent work by SDI satisfied Dr. Huyakorn and the District, which issued the TSR and proposed CUP at issue in May 2006 based in part on SDI's March 2006 MODFLOW model, despite Petitioners' criticisms. The final hearing was continued until September 2006 to give Petitioners time to complete discovery on SDI's March 2006 MODFLOW model (as well as the City's new solute transport modeling, which is discussed, infra). To calibrate its March 2006 MODLFOW, SDI first used a transient MODFLOW model to simulate data from the 4-day aquifer performance test (APT) from the Area IV Wellfield sites (the transient APT calibration). (A transient model is used to analyze time-dependent variable conditions and produces a time- series of simulated conditions.) Then, after calibrating to the APT data, SDI used a steady-state, non-pumping MODFLOW model (a time-independent model used to analyze long-term conditions by producing one set of simulated conditions) to simulate the static head difference between the SAS and UFAS (the steady- state head difference calibration). If the head difference simulated in the steady-state calibration run did not match the measured head difference, the ICU leakance was adjusted, and then the revised parameters were rechecked in another transient APT calibration run. Then, another steady-state head difference calibration run was performed in an iterative process until the best match occurred for both calibration models. In order to achieve calibration, SDI was required to make the ICU leakance value several times tighter than the starting value, which was the value derived in the site-specific APT using conventional curve-matching techniques (and relatively close to the values ascribed to the region in general in the literature and in two regional models that included Area IV near the boundary of their model domains--namely, the District's East Central Florida (ECF) model, which focused on the Orlando area to the south and west, and its Volusia model, which focused on Volusia County to the north). SDI's calibrated ICU leakance value derived from calibration to observed static head differences is more reliable than an ICU leakance value derived from an APT using conventional curve-matching techniques. That leaves a question as to the quality of the static head difference measurements used for SDI's calibration. BFA took static head measurements at SAS and UFAS monitor wells located at Test Sites 1, 2 and 3 in January 2004, April 2004, and July 2006. On each occasion, a downward head gradient was noted at each site, meaning the water table (i.e., the SAS) had a higher elevation than the potentiometric surface of the UFAS. In January 2004, the measured head difference at Test Sites 1, 2 and 3 were 6.2 feet, 5.5 feet and 5.9 feet, respectively. In April 2004, the measured head differences at Test Sites 1 and 3 were 8.1 feet and 8.1 feet, respectively. In July 2006, the measured head differences at Test Sites 1, 2 and 3 were 8.6 feet, 6.6 feet and 9.3 feet, respectively. The average of these observed head differences for the Area IV Wellfield was 7.46 feet. BFA's static head difference measurements included both wet and dry seasons. The measurements do not show significant differences between seasons and suggest that static head difference remains fairly constant at the Area IV Wellfield year round. This is typical of head difference data collected from hundreds of other Florida locations because the hydrologic systems seek equilibrium. Petitioners questioned taking an average of the head difference measurements because the region had experienced a rainfall deficit of 17 inches over the 12 months prior to time the measurements in July 2006 were taken. By itself, a rainfall deficit would not affect head difference measurements because the hydrologic system would seek equilibrium. But there was evidence of a possibly significant rainfall near Area IV not long before the July 2006 measurements. If significant rain fell on Area IV, it could have increased the static head differences to some extent. But there was no evidence that such an effect was felt by Area IV. Petitioners also contend for several other reasons that the static head differences used by SDI as a calibration target were "not what they are cracked up to be." They contend that "limited spatial and temporal extent . . . renders them inappropriate calibration targets." But while the site-specific static head difference measurements were limited, and more measurements at different times would have increased the reliability of the average static head difference used in SDI's steady-state calibration, the head difference measurements used were adequate. For a groundwater model of Area IV, they were as good as or better than the head differences used by Petitioners' expert modeler, Mr. LaFrenz of Tetratech, who relied on SAS and UFAS head levels from the regional-scale ECF model, which were measured by the United States Geological Survey (USGS) in May and September 1995. Petitioners also contended that the measured head differences used by SDI for the steady-state calibration of the March 2006 MODFLOW model were significantly higher than other measured head differences in the general vicinity of Area IV. One such location is Long Lake, which has saltwater and an obviously upward gradient (i.e., a negative head difference between the SAS and UFAS), whereas SDI's MODFLOW depicts it as having a five-foot downward gradient (positive head difference). However, all but one of those measurements (including from Long Lake) were from locations five or more miles from Area IV. In addition, the accuracy of the measurements from the closer location (and all but one of the more distant locations) was not clear, so that the seemingly inconsistent head differences measurements may not be indicative of actual inconsistency with the head difference measurements used by SDI. Petitioners also accused the City and its consultants of "playing games with specific yield" to achieve calibration with a tighter-than-appropriate ICU leakance value. But the City and the District adequately explained that there was no merit to the accusations. It was appropriate for SDI to use just the relatively small specific storage component of SAS storativity (the 0.001 value) in its transient calibration runs, instead of the larger specific or delayed yield component. Storativity is not utilized at all in the MODLFOW steady-state calibration runs and steady-state simulations. Based on the foregoing, it is found that Petitioners' factual disputes regarding SDI's calibrated ICU leakance value do not make the City's assurance of no unacceptable drawdown provided by its MODFLOW simulations unreasonable. That leaves several other issues raised by Petitioner with regard to the SDI's March 2006 MODFLOW model. In calibrating its MODFLOW model, SDI utilized a value for the MCU leakance that was twice as leaky as the published literature values for the area, which Petitioners claim would reduce simulated SAS drawdown. Although the use of a higher MCU leakance value in the model may result in a prediction of less SAS drawdown, the actual effect, if any, on the predicted drawdown, was not made clear from the evidence. In any event, an MCU leakance value for Area IV calibrated to site-specific data is more reliable than regional values. Petitioners also accused the City and its consultants of using inappropriate or questionable boundary conditions, topography, and depth to the water table. They also contend that incorrect topography--namely, a nonexistent five-foot ridge or mound northwest of Area IV--provides an artificial source of water for SDI's March 2006 MODFLOW model. But the boundary conditions for SDI's March 2006 MODFLOW model were clear from the evidence and were appropriate; and SDI's topography and water table depth were reasonably accurate (and on a local scale, were as or more accurate than the USGS topographic maps Petitioners were comparing). Besides, Dr. Huyakorn ran the Tetratech model with SDI's leakance value instead of Tetratech's value and got virtually the same drawdown results, proving that differences in topography between the two models made virtually no difference to the drawdown predictions of either model. As for the so-called "flow from nowhere," particle-tracking simulations conducted by experts from both sides established that, with pumping at 2.75 mgd, no water would enter the Area IV production zone from anywhere near the five-foot ridge area for at least 100 years. This gave reasonable assurance that the five-foot ridge or mound had no effect on the simulated results from SDI's March 2006 MODFLOW model. Petitioners also contend that the City's failure to simulate drawdown from pumping during the dry season, as opposed to a long-term average of wet and dry seasons, constituted a failure "to provide reasonable assurances as to the conditions that can be expected as a result of the anticipated operation of the wellfields." But the evidence was clear that long-term, steady-state groundwater model simulations are appropriate and adequate to provide reasonable assurance for CUP permitting purposes. See "Drawdown Impacts," infra. By definition, they do not simulate transient conditions such as dry season pumping. The SDI model predicts a maximum drawdown, from a 2.75 mgd withdrawal from all fifteen UFAS production wells and a 0.18 mgd withdrawal from the four SAS extraction wells, of slightly less than 0.5 feet in the SAS and of 12.0 feet in the UFAS in the immediate vicinity of the Area IV Wellfield. SDI’s model predicts a drawdown of 0.11 feet (approximately 1 inch) in the SAS and a drawdown of 2.2 feet in the UFAS at Ms. Clark’s property, which is located approximately 1 to 1.5 miles north of the Area IV Wellfield. It is found that SDI's March 2006 MODFLOW model for Area IV is the best such model in evidence. That is not to say that the drawdown predicted by SDI's model is a certainty. The other models were not proven to be better than SDI's, but they did demonstrate that simulated results would vary significantly in some cases if SDI's calibration and calibrated ICU leakance values were incorrect. Having more good hydrologic information would have made it possible to reduce the uncertainties present in SDI's model, but it is found that SDI's March 2006 MODFLOW model was sufficient to give reasonable assurance as to SAS and UFAS drawdown from pumping at 2.75 mgd from the UFAS and 0.18 mgd from the SAS for wetland augmentation. Drawdown Impacts As indicated, once drawdown is predicted with reasonable assurance, both interference with existing legal uses and impacts on wetlands, which relate to public interest, must be evaluated. Interference with Legal Uses Using SDI's March 2006 MODFLOW model, the City gave reasonable assurance that the drawdown predicted from pumping at 2.75 mgd from the UFAS and 0.18 mgd from the SAS for wetland augmentation will not interfere with existing legal users. The nearest existing legal users are located about one mile northwest and two miles east/southeast of the nearest proposed production well. The City’s MODFLOW modeling scenarios indicate that maximum drawdown in the SAS will be less than 0.5 feet and minimal (at most 2.2 feet) in the UFAS at the nearest active existing legal users. Obviously, drawdown would be much less at 0.5 to 0.75 mgd from the UFAS (with probably no wetland augmentation required). As indicated, the drawdown predicted by SDI's March 2006 MODFLOW model is not a certainty. Although not likely based on the more persuasive evidence, if actual drawdown approximates the drawdown predicted by the Tetratech model, there could be interference with existing legal users. (The Tetratech model predicts that the long-term average reduction in the water table of approximately 1.6 feet of drawdown near the center of the wellfield and drawdown of 0.4 feet to 0.5 feet extending out more than a mile from the proposed Area IV Wellfield.) There probably still would be no interference with existing legal users with pumping at 0.5 to 0.75 mgd from the UFAS (with probably no wetland augmentation required). In the event of that much actual drawdown and unanticipated interference from the City’s pumping, “Other Condition” 15 of the proposed permit requires that it be remedied. See Finding 36, supra. There is no reason to think such interference could not be remedied. Environmental Impacts from Drawdown Miami Corporation’s property in the vicinity of the proposed Area IV Wellfield is a mosaic of pine flatwoods uplands interspersed with wetlands. The wetlands are mostly cypress swamps, with some areas of hardwood swamp, marshes, and wet prairies. Miami Corporation's property is managed for timber and is also used for cattle grazing and hunting. Miami Corporation has constructed a network of roads and ditches on its property, but overall the wetlands are in good conditions. The areas east and west of the proposed Area IV Wellfield consist of cypress strands, which are connected wetlands. Compared to isolated wetland systems, connected wetlands are typically larger, deeper, and connected to waters of the state. They tend to have hardwood wetland species. Connected wetlands are less vulnerable to water level changes brought about by groundwater withdrawals because they tend to be larger systems and have a greater volume of water associated with them. They are able to withstand greater fluctuations in hydroperiods than isolated herbaceous wetland systems. Isolated wetland systems are landlocked systems. They tend to be smaller in size and shallower than connected wetland systems. Isolated systems tend to be more susceptible to changes in hydrology than larger connected systems. The upland plant communities present near the proposed Area IV Wellfield include pine flatwoods that have been altered by Miami Corporation's timber operations. There is a large area surrounding the Area IV Wellfield to the north that consists of forest regeneration after timbering. There was evidence of the presence of the following listed animal species at the site of the proposed Area IV Wellfield: wood storks, roseate spoonbills, ibis, bald eagles, Sherman fox squirrels, American alligator, sandhill cranes, wood storks, black bear, and indications of gopher tortoises. The habitat in the vicinity also supports a number of other listed species that were not observed. The following listed plants species were also observed during the environmental assessment and site visits: hooded pitcher plants, water sundew, pawpaw and yellow butterwort. Ms. Clark’s property adjoins a cut-over cypress swamp on the western side of her property, and there is also a small man-made fish pond in her backyard. Some clearing has taken place in the wetland system on the back portion of Ms. Clark’s property. What appears to be a fire break on Ms. Clark’s property encroaches upon the wetland system. The wetlands on Ms. Clark’s property have experienced some human activities such as trash dumping and clearing, which have resulted in a degradation of those systems. Some trees within the wetland systems on the back portion of Ms. Clark’s property have been logged. For the most part, the hydrology appears to be normal. However, some invasive species have encroached upon the system due to the clearing that has taken place. There was no evidence of listed plant or animal species present on Ms. Clark’s property. If drawdown is of the magnitude predicted by the SDI's March 2006 MODFLOW model, unacceptable environmental impacts from drawdown would not be anticipated. At 0.5 or 0.75 mgd, there clearly would not be any unacceptable environmental impacts. In addition, “Other Condition” 12 of the proposed permit requires the City to perform extensive environmental monitoring. The environmental monitoring plan proposed for the Area IV Wellfield provides reasonable assurance that changes to wetland hydrology and vegetation due to groundwater withdrawals will be detected before they become significant. “Other Condition” 12 of the proposed permit prohibits the City from pumping any water from the production wells until the monitoring network is in place. The baseline monitoring will give a clear indication of the existing conditions prior to the production wells coming on-line. Once the production wells are online, the City will continue the same procedures that they conducted prior to the production wells coming online. This will allow the City and the District to monitor the effects of pumping. The City’s proposed environmental monitoring plan is adequate to detect drawdown impacts and is consistent with environmental monitoring plans that have been developed for other wellfields throughout the State of Florida. Since the City has given reasonable assurance that there will not be environmental harm from drawdown, the proposed permit does not propose mitigation. If unanticipated harm is detected, “Other Condition” 24 of the proposed permit requires the City to implement an avoidance and minimization plan to rehydrate the wetlands and restore the water levels to normal levels and natural hydroperiods by augmenting the water in the affected wetlands with water pumped from SAS wells and piped to the affected wetlands. “Other Condition” 24 includes specific timeframes for implementing wetland rehydration in the event unanticipated impacts were to occur. In addition, the City could, on its own, change its pumping schedules. If an impacted wetland is near a particular well, the City could reduce or shut off water withdrawals from that well and thereby restore water levels in the wetland. Direct augmentation of wetlands has been used at other facilities such as those of Tampa Bay Water and Fort Orange. The direct augmentation at these other sites appears to be effective. Direct augmentation of wetlands has proven to be a feasible means of offsetting adverse changes in wetlands due to groundwater withdrawals, at least in some circumstances. There is a viable source of water that can be utilized to augment these wetland systems, namely a large canal south of the production wells. Based on the predicted drawdown, SDI estimated the quantity of water needed for implementation of the avoidance and minimization plan to be 0.18 mgd. The water quality in the canal is comparable to the water quality within any wetland systems that would be affected by drawdown. The City plans to have its augmentation plan in place prior to the production wells coming online. In that way, if changes are observed within the wetland systems, the augmentation plan could be implemented in relatively short order to alleviate any impacts that might be occurring as a result of the production wells. The success of the augmentation plan depends on the extent of actual drawdown. If actual drawdown approximates Tetratech's predictions, environmental impacts would not be acceptable, and there would not be reasonable assurance that the augmentation plan would be sufficient to mitigate the environmental impacts. If drawdown is of the magnitude simulated in the City’s MODFLOW model, reasonable assurance was given that, if needed, the avoidance and minimization plan developed for the Area IV Wellfield would be capable of offsetting any adverse changes in wetlands and other waters detected through the environmental monitoring plan. If the City pumps not more than 0.75 mgd, the avoidance and minimization plan developed for the Area IV Wellfield probably would be unnecessary but certainly would be capable of offsetting any adverse changes in wetlands and other waters that would be detected through the environmental monitoring plan. If unanticipated environmental harm occurs due to excessive actual drawdowns, and the harm cannot be avoided either by the augmentation plan or by altering the pumping schedule, or both, the District can revoke all or part of the permit allocation under “Other Condition” 23. This ability gives reasonable assurance that no unacceptable environmental harm will occur even if actual drawdown approximates Tetratech's predictions. Saltwater Up-coning and Intrusion Predicting saltwater movement towards the production zone of the proposed Area IV Wellfield is important to several permitting criteria, including interference with existing legal uses and the ability of the resource to provide the requested allocation of freshwater, both of which relate to the public interest. During the permit application review process, the City submitted a succession of models to provide reasonable assurance that the proposed Area IV Wellfield would not result in unacceptable saltwater intrusion. Initially, BFA prepared and submitted solute transport simulations using an analytical model known as the “UPCONE Model.” The District initially accepted the submission as providing reasonable assurance to support the District's initial TSR. Despite Miami Corporation's petition, the City and the District maintained that reasonable assurance had been given that operation of Area IV would not result in unacceptable saltwater intrusion based on the "UPCONE Model." As indicated, supra, Miami Corporation's petition was scheduled for a final hearing in June 2005, but the hearing was continued until February 2006. As the case proceeded towards a final hearing in February 2006, the City not only turned to SDI to develop the numerical MODFLOW model, it also turned to SDI to develop a numerical solute transport model that would couple the MODFLOW groundwater flow equations with advection dispersion solute transport equations to simulate the movement of variable density saline groundwater in response to stresses. In addition to the initial boundary conditions, aquifer parameters and stresses specified for a groundwater model, a solute transport model requires solute parameters such as chloride concentrations, dispersivity and effective porosity. SEAWAT is a solute transport model code that combines the MODFLOW, which provides the groundwater flow component, with the MT3DMS code, which provides the mass transport component. When coupled with MODFLOW, the MT3DMS code tracks the movement of variable density water and performs internal adjustments to heads in the flow model to account for water density. Like MODFLOW, SEAWAT is capable of simulating the important aspects of the groundwater flow system, including evapotranpiration, recharge, pumping and groundwater flow. It also can be used to perform both steady-state or transient simulations of density- dependent flow and transport in a saturated zone. It was developed in the late 1990s and is rapidly becoming the standard for solute transport modeling throughout the United States. It is used by many water management agencies in the State of Florida. Initially, SDI used SEAWAT version 2.1 to simulate movement of saline water towards the Area IV Wellfield. The first such simulation was prepared in March 2006 using manually- adjusted head values along the eastern model boundary. It incorporated SDI's March 2006 MODFLOW model. The District, in consultation with Dr. Huyakorn, required SDI to perform what was termed a "sensitivity run" with reduced chloride concentrations in the eastern boundaries (5,000 mg/l versus 19,000 mg/l) to better match actual measurements recorded in wells in the vicinity. In April 2006 SDI prepared and submitted those simulations. After reviewing the March and April 2006 SEAWAT 2.1 simulations, Petitioners' consultants criticized the manner in which starting chloride concentrations in the vicinity of the Area IV Wellfield were input into the models. In those models, SDI had input initial chloride concentration at 50 mg/l throughout the depth of the UFAS. The model was then run for 100 years with no pumping to supposedly arrive at a reasonable starting chloride concentration for the UFAS. Then, the model was run for 25 years with pumping at 2.75 mgd. However, the initial chloride concentrations at the beginning of the pumping run still did not comport well with actual measurements that were available. After Petitioners raised the issue of the starting chloride concentrations assigned to the UFAS in SDI's March and April 2006 SEAWAT 2.1 runs, the final hearing was continued until September 2006 to give Petitioners time to complete discovery on those models (as well as on SDI's March 2006 MODFLOW model, as discussed supra). During a deposition of Dr. Huyakorn in July 2006, he recommended that the District require SDI to perform another simulation (also termed a "sensitivity run") using starting chloride concentrations more closely comporting with known measurements. (There also were some changes in the constant chloride concentrations that were part of the boundary conditions on the western side of the model domain.) This resulted in SDI's early August 2006 SEAWAT 2.1 simulation of 15 years of pumping at 2.75 mgd. Petitioners also criticized the City for not using a newer version of SEAWAT, called SEAWAT 2000, as well as for using chloride concentrations as inputs for its SEAWAT 2.1 model simulations instead of total dissolved solids (TDS). (SEAWAT 2.1 required input of TDS, not chlorides; SEAWAT 2000 allowed chlorides to be input. Not until the last day of the final hearing was it pointed out by Dr. Huyakorn that using chlorides instead of TDS caused SDI's SEAWAT 2.1 simulations to over- predict saltwater intrusion.) As a result of Petitioners' criticisms, the City had SDI re-run both the April and early August SEAWAT 2.1 models in late August 2006 using SEAWAT 2000 (which the City and the District also termed "sensitivity runs.") Because the SEAWAT 2000 simulations would be time- barred from use in the City's case-in-chief under pre-hearing requirements, and whether they could be used in rebuttal could not be determined at that point in time, the City requested another continuance, this time until December 2006, to give Petitioners time to discover the SEAWAT 2000 model simulations. During Petitioners' discovery of SDI's August SEAWAT 2000 model simulations, it came to SDI's attention that SDI was not calculating mass outputs from the model correctly. Those errors were corrected by SDI in September 2006. SDI's corrected August 2006 SEAWAT 2000 simulation predicted that, after 15 years of pumping at 2.75 mgd, the chloride concentration in the Area IV production wells would increase from 54 mg/l to 227 mg/l. After the 15-year pumping run, SDI's corrected August 2006 SEAWAT 2000 simulation predicted that the chloride concentration in several of the southernmost production wells would exceed 250 mg/l. At 17.5 years of the pumping run simulation, the simulation predicted that the entire wellfield would have chlorides in excess of 250 mg/l. That prediction does not, however, mean the chloride concentration in these wells will exceed 250 mg/l in actual operation. The SDI model contains several conservative assumptions that magnified the potential chloride concentrations in those wells. First, it was assumed all the production wells would be drilled to 250 feet below land surface, while the City will likely drill the southernmost wells to a shallower depth. Additionally, the wellfield production rate used in the model was not optimized for water quality. Finally, the model was not set up to simulate a wellfield operation plan that turned wells on and off based on the saline water monitoring plan. For the sake of simplicity, the model assumed that all the wells would operate 24 hours a day, 7 days a week, for the entire 15 year period. Petitioners continued to maintain for several reasons that SDI's SEAWAT models do not provide reasonable assurance that operation of the Area IV Wellfield will not result in unacceptable saltwater intrusion. Chlorides versus TDS Petitioners criticized SDI's corrected SEAWAT 2000 model for still not inputting chlorides correctly. While SEAWAT 2000 allows the input of chlorides instead of TDS (and input of chlorides instead of TDS is recommended since chloride is a more stable chemical than some of the other components of TDS), they must be input correctly. However, while Petitioners demonstrated that the chlorides were not input correctly, causing the model to under-calculate fluid density, Dr. Huyakorn clarified in rebuttal that under-calculating fluid density caused SDI's SEAWAT 2000 models to over-predict saltwater intrusion into the wellfield. Starting Chloride Conditions Petitioners continued to question the representation of initial chloride concentrations in the SEAWAT models. SDI's SEAWAT models included multiple vertical grid layers to represent conditions better than the layering used in the MODFLOW set-up. The SAS was represented by layer 1, the ICU by layer 2, the UFAS by layers 3 through 14, the MCU by layer 15, and the LFAS by layers 16 and 17. SDI used a chloride concentration of 0 mg/l for the SAS and ICU in its August 2006 SEAWAT model, which probably does not represent the actual initial condition but is probably close enough since the SAS is recharged by rainfall that typically has very low (1 to 2 mg/l) chloride levels. SDI used a chloride concentration of 2,500 mg/l for the MCU and a chloride concentration of 5,000 mg/l for the LFAS in its August 2006 SEAWAT model, which are reasonable initial chloride values for the Area IV Wellfield. To develop the initial chloride concentration conditions of the UFAS for its August 2006 SEAWAT model, SDI first plotted the available water quality data (63 well-data points) on a map of the Area IV Wellfield area. After examining the distribution of the data, SDI divided the UFAS into two layers to represent the upper UFAS (above –200 feet NGVD) and the lower UFAS (below –200 feet NGVD). Then, using various scientific studies containing chloride concentration maps, groundwater recharge/discharge maps (recharge indicating an area is more likely to have low chlorides in the UFAS and discharge indicating an area is more likely to have high chlorides), and maps showing the shape and extent of the freshwater lens in the area, plus SDI’s own knowledge of groundwater flows and expected higher chloride concentrations along the coast and St. Johns River, SDI used scientifically accepted hand-contouring techniques to represent the initial chloride concentration conditions of the upper and lower UFAS on maps. SDI’s two hand- contoured chloride concentration maps were reviewed and accepted by the District’s experts and reflect a reasonable representation of the initial chloride concentration conditions in the UFAS in the Area IV Wellfield. Using the two hand- contoured chloride concentration maps, SDI input the chloride concentration values from those maps into its August 2006 SEAWAT model. The chloride concentration values from the upper UFAS map were input into layers 3 through 7 of SDI’s August 2006 SEAWAT model. The chloride concentration values from the lower UFAS map were input into layers 11 through 14 of SDI’s August 2006 SEAWAT model. SDI input the average of the chloride concentration values from the upper and lower UFAS layers into the middle UFAS (layers 8 through 10). It is appropriate to average the chloride values between the upper and lower UFAS in the Area IV Wellfield because the saline water interface is not that sharp and occurs near the bottom of the UFAS (unlike conditions 11 miles to the south). Petitioners accuse SDI, the City, and the District of ignoring unfavorable chloride data in setting up its August 2006 SEAWAT 2000 model. The evidence was that all chloride data was considered and evaluated. Mr. Davis and the District's experts did not rely on the 450 mg/l chloride packer test measurement taken from the interval between 270 and 295 feet at Test Site 3 in preparing the contour maps of the UFAS because the chloride measurement was deemed inaccurate because the sodium to chloride ratio is out of balance. Mr. Davis and the District's experts did not utilize the 2,336 mg/l and 2,717 mg/l chloride concentration packer test measurements at 442-500 feet below land surface at Test Sites 1 and 3 to prepare the chloride contour maps for the UFAS because they believed these measurements from the MCU. Mr. Davis and the District's experts deemed it inappropriate to utilize a 845 mg/l chloride value reported for Test Site 2 to prepare the chloride contour for the lower portion of the UFAS because this sample was collected at just 210 feet below land surface and because a 500 mg/l contour line separates a 882 mg/l measurement at Test Site 1 from a 134 mg/l measurement at Test Site 3. The decision not to include the Test Site 2 data also is supported by the particle tracking modeling prepared by the Petitioners and the City using the groundwater component of the SDI SEAWAT model and the TetraTech model, which show that water from Test Site 2 will not enter the Area IV production wells for at least 100 years with pumping at 2.75 mgd. The chloride contour maps developed by Mr. Davis and the District experts were consistent with previous studies conducted by the USGS and the District in the region. For example, the chloride contours shown on City Exhibit 142 for the upper portion of the UFAS are generally consistent with Figure 35 of the 1990 USGS Report by Charles Tibbals and Figure 15 of the 1999 District Report by Toth and Boniol. The two chloride contour maps developed by Mr. Davis and the District's experts are a reasonable representation of the existing water quality of the UFAS in the region of the Area IV Wellfield based on the available data. Mr. Davis used the 882 mg/l chloride concentration packer test measurement from the interval between 331 and 400 feet at Test Site 1 as the starting chloride concentration in four grid cells at the bottom of the UFAS, which Petitioners' experts referred to as a "pinnacle" or "column," that were assigned a chloride value of 700 mg/l. While the representation may not have been realistic, and the "pinnacle" or "column" quickly "collapses" when the model begins to run, the representation was a concession to the existence of the datum even though it appeared at odds with water quality collected from a packer test at Test Site 3 at the same depth interval, which was much fresher. District staff agreed with Davis’ approach to representing the saltier packer test measurement from Test Site 1. The initial chloride concentrations developed for the UFAS by Mr. Davis and District staff are not inconsistent with the water quality data collected by the Petitioners’ consultants from Long Lake. The lake is located in an area of the map where the chloride concentration in the UFAS, which discharges into the lake at that location, is between 1,000 and 5,000 mg/l. Mr. Davis decided not to use 2,000 mg/l to represent the bottom layer of the UFAS even though the bottom packer tests performed at Test Sites 1 and 3 showed an average value of 2,000 mg/l at the approximate boundary of the UFAS and the MCU. Instead, he decided to associate this chloride concentration with the MCU because even if the packer had penetrated a portion of the UFAS, he did not believe the measurement was representative of static water quality conditions at that depth. The packers had been pumped for over 4 hours at 25 gpm at Test Site 1 and over 4 hours at 85 gpm at Test Site 3, which could have doubled or tripled the static chloride concentration. As was later shown in sensitivity runs by Petitioners' expert, Dr. Guo, if SDI had incorporated the 2,000 mg/l value at the bottom of the UFAS, the model simulation would have shown unrealistically high initial chloride concentrations in the production wells at the start of pumpage when compared to the water quality measured during the APTs conducted at Test Sites 1 and 3. (While only one well was pumping at a time, versus the 15 in the model simulations, the single APT well was pumping at approximately three times the rate of the 15 wells in the model simulation.) Based on all the evidence, it is found that the chloride concentrations used in SDI’s August 2006 SEAWAT model reflect a reasonable representation of the initial chloride concentration conditions in the UFAS in the Area IV Wellfield and were properly input into that model using an appropriate method. Location of the MCU Related to the last point is Petitioners' claim that the top of the MCU (i.e., bottom of the UFAS) is incorrectly represented in SDI's SEAWAT models at 450 feet below sea level (approximately 425 feet below land surface). They point to literature values indicating that the depth to the MCU is up to 150 feet greater. However, these reports did not include site- specific data or test wells in the vicinity of the Area IV Wellfield or in northern Brevard County. It was reasonable to consider and rely on site-specific information regarding the depth to the MCU in this case. BFA determined the approximate location of the MCU by examining cuttings collected during drilling at APT well sites 1 and 3 and by measuring various properties of the aquifer with down-hole geophysical techniques. Based on the site-specific information obtained, the depth to the MCU was determined to be approximately 450 to 475 feet below land surface or –425 to -450 feet NGVD. The lithologic log for well site 1 indicates the presence of gray/tan limestone between 450 to 460 feet below land surface and light/gray limestone and dolomitic limestone from 460 to 470 below land surface. The lithologic log for well site 3 indicates the presence of tan dolomitic limestone from 450 to 460 feet below land surface and tan limestone and dolomitic limestone from 460 to 470 feet below land surface. According to Petitioners' own expert, Dr. Missimer, the change to a mixture of limestone and dolomite is evidence of the MCU. After examining the video log for well site 1, Dr. Missimer noted a “lithologic change” at 477 feet below land surface (while still disputing BFA's conclusion that the MCU started there.) One characteristic of the MCU is a lower resistivity. At well site 1, a reduction in resistance occurred at approximately 470 feet below land surface. Another characteristic of penetrating the MCU is decrease in flow. The flow meter log for well site 1 suggests a decrease in flow at approximately 450 feet below land surface. On the other hand, it also is true that wells drilled completely into the MCU probably would not produce more than approximately 5 gallons per minute (gpm), whereas the packer test at the bottom of Wellsite 1 was yielding 25 gpm, and the packer test at the bottom of Wellsite 3 was producing 85 gpm. It is possible that the bottom packers were open to both the UFAS and the MCU, which could explain the higher flows. Petitioners maintain that BFA stopped drilling too soon (500 feet below land surface, or 475 feet below sea level) to ascertain the actual depth to the MCU. While it is true that drilling deeper would have made BFA's determination as to the depth to the MCU more convincing and certain, BFA's approximation of the depth to the MCU was reasonable for purposes of SDI's SEAWAT model. To the extent that BFA might have been wrong on the depth to the MCU, there was no convincing evidence that the error would have made SDI's SEAWAT model results unreliable. To the contrary, Dr. Huyakorn testified that, even if SDI put the MCU 75 feet too high, the label given to the interval is not critical to the reliability of the modeling results. More important are the parameters for transmissivity and leakance assigned to aquifers and confining units. Dr. Huyakorn testified that, given the aquifer parameters assigned to the intervals, SDI's SEAWAT modeling results would be reasonably reliable. Saline Movement Impacts As indicated, once chloride concentration changes are predicted with reasonable assurance, both interference with existing legal uses and the ability of the resource to provide the requested allocation of freshwater, which relate to public interest, must be evaluated. Significant saline water intrusion is defined as saline water encroachment which detrimentally affects the applicant or other existing legal users of water, or is otherwise detrimental to the public. (Rule 9.4.2, A.H.). Saline water may encroach from upconing or the vertical movement of saline water into a pumping well, and it may encroach laterally to the well from a saline waterbody like the ocean. The proposed use associated with the four surficial aquifer extraction wells is so minimal that it clearly would not cause saline water intrusion or harm the quality of this proposed source of water. The focus of attention is the production wells. The evidence was sufficient to provide reasonable assurance that the proposed consumptive use from the Area IV Wellfield will not cause significant saline water intrusion; further aggravate currently existing saline water intrusion problems; induce significant saline water intrusion to such an extent as to be inconsistent with the public interest; or harm the quality of the proposed source of water. First, the long-term constant rate pump tests, which were conducted as part of the APT, give some indication of the potential for saltwater intrusion. While only one well was pumping during the tests, water quality did not degrade at pumping rates that far exceeded what would be approved as part of the proposed permit. During four-day pump tests in which the wells at sites 1 and 3 were pumped at approximately 1 mgd, chlorides never exceeded approximately 74 mg/l. Second, while (as with drawdown predicted by the groundwater flow modeling) saltwater movement predicted by the City’s SEAWAT simulations is not a certainty, the simulations gave reasonable assurance that the requested allocation could be withdrawn from the Area IV Wellfield without excessive changes to water quality (specifically chlorides) and that there is an adequate thickness of freshwater at the Area IV Wellfield that could supply the requested allocations of water for 15 years without saline water intrusion, especially since it is unlikely that a number of the wells will actually be constructed to the 250-foot depth assumed in the model, particularly as one moves south along the railroad right-of way. Third, it is even more unlikely that saltwater intrusion will occur before the proposed permit expiration in 2010. Due to the time required to construct the facility, it is anticipated that the Area IV Wellfield will become operational in 2009. Assuming the City seeks to renew the permit, there would be more information on saltwater intrusion for the District to consider on permit renewal. Since the City provided reasonable assurance as to its proposed withdrawals from Area IV, there clearly is reasonable assurance that withdrawal of not more than 0.75 mgd from Area IV would not result in significant saline intrusion. The TSR includes proposed “Other Condition” 11 which requires the installation of saline monitor wells. The spatial distribution of these wells is such that the beginning of water quality degradation or saltwater intrusion, either from upconing or lateral intrusion, would not occur without it being detected by these wells. In addition to these monitor wells, proposed “Other Condition” 14 requires water quality samples to be collected from each production well. These wells are to be sampled quarterly for a suite of parameters, including chlorides. “Other Condition” 25 is proposed as a “safety net” should unanticipated saltwater intrusion occur. If any production well shows a concentration of 250 mg/l chlorides, then this proposed condition would prohibit further use of the well until the chloride concentration drops. If the monitoring shows a chloride concentration in a production well of 200-to- 249 mg/l, the well will be placed on restricted use. A production well may be placed back into regular service once the chloride concentration in the well is below 200 mg/l. Other Issues Other issues raised and maintained by Petitioners in this case include: whether the City has provided reasonable assurance that it owns or controls the property upon which the proposed wellfield will be located; whether the Area IV Wellfield is an economically feasible option; whether the City has provided reasonable assurance that it will be able to implement the project before the expiration date of the proposed permit; whether the proposed CUP is inconsistent with the District's designation of Priority Water Resource Caution Areas; whether the proposed CUP constitutes an impermissible modification of the existing CUPs for Areas II and III; and whether the City failed to pay the appropriate permit fee. Ownership or Control The City has obtained an easement from the Florida East Coast Railway (FEC) to use FEC right-of-way for the City's proposed production wells. It does not yet have ownership or control of land needed for all wetland and saline monitoring sites, or for wetland augmentation if necessary, but intends to acquire the right to use all land needed through negotiation or exercise of eminent domain. Petitioners contend that the FEC easement is insufficient for several reasons: the easement is "without warranty or covenants of title of any kind"; it is impossible to define the precise boundaries of the easement because the easement is defined in terms of distance from the center of a railroad bed that existed in 1866 but no longer exists; and the precise location of proposed production wells is not definite. While the easement is "without warranty or covenants of title of any kind," the evidence is that, if contested, the precise boundaries of the easement would be difficult but not necessarily impossible to define. It is reasonable to anticipate that at least Miami Corporation will contest the legality and extent of the FEC easement. Petitioners allege that there is confusion about the location of the proposed wells because some well locations identified in the City’s permit application did not match the coordinates assigned to certain production wells on the District’s on-line database. Actually, there is no confusion regarding the location of the wells; the well locations identified in the permit application were the well sites used for modeling purposes and for review of the application. District staff explained that the well site locations identified in the District’s database would be finalized after the wells are constructed and the exact locations have been identified using GPS technology. Contrary to Petitioners' contentions, the District’s rules do not require that an applicant own the property where the proposed production wells or monitoring wells are to be located. The District has issued many CUPs where either the subject property or the property associated with the monitoring requirements of the permit are not owned by the applicant. Recent examples include the CUPs for Orange County Utilities and the Orlando Utilities Commission. This makes sense when the applicant has the power of eminent domain or some other credible means of obtaining necessary ownership or control, such as an option contract. The District’s permit application form has a section that requires the applicant to identify who owns or controls the land on which the facility will be located. The District uses this information for noticing and contact information. Contrary to Petitioners' contentions, this section of the permit application form is not intended to create a substantive permitting standard requiring property ownership before a consumptive use permit can be issued. Petitioners argue that proof of ownership or control is necessary to determine whether a drawdown from a proposed water use will adversely affect stages or vegetation on lands other than those owned, leased, or otherwise controlled by the applicant. However, the evidence was that these impacts can be assessed based on the facts of this case. The City's need to eventually obtain ownership or legal control to exercise the rights granted by the proposed CUP may be problematic in this case and is a factor to be considered in the next two issues raised and maintained by Petitioners: whether the Area IV Wellfield is an economically feasible option; and whether the City has provided reasonable assurances that its project can become operational before the expiration date of the proposed permit. But it is not a reason to automatically deny the City's proposed CUP. Economic Feasibility Petitioners argue that the proposed Area IV Wellfield is too expensive and that the expense should be a factor in deciding whether it is in the public interest. But cost to the City is not a factor in determining whether to issue the CUP proposed in this case. Statutes and rules cited by Petitioners on this point do not apply to this CUP determination. See Conclusions of Law 277-279, infra. Implementation Before Expiration Date Litigation of a case filed by Miami Corporation to contest the legality and extent of the City's FEC easement will add to the (cost and) time necessary to implement the project. This additional time was not specifically taken into account by the City in estimating the time it would take to implement the project. The (cost and) time for litigation of the legality and extent of the City's FEC easement could be spared by exercising eminent domain instead. That probably would add to total the cost of eminent domain but might not add appreciably to the time necessary for acquisition of required ownership or control. In an imprecise way, the time for eminent domain proceedings necessary to gain ownership or control of land for monitoring sites and wetland augmentation (without time for litigation of a contest over the legality and extent of the FEC easement, or for using eminent domain instead) was factored into the time estimated for implementation of the project. With this rough estimate, the evidence was that the project could be expedited and completed in 33 months from issuance of a CUP. It is possible but not probable that the project could be implemented in less than 33 months. It is possible and more probable that it will take longer than 33 months to implement the project. In a worst case scenario, it could take as much as 59 months complete the project. But 33 months is a reasonable, if optimistic, estimate (without time for litigation of the legality and extent of the FEC easement, or for using eminent domain instead). As found, the proposed CUP expires at the end of 2010. Given the 33-month estimate for implementation (without time for litigation of a contest over the legality and extent of the FEC easement), the CUP would have to be issued by March 2008 to be completed before expiration. Given that estimate, it would be in operation for six months before expiration. It is likely that the City will apply to renew both the existing CUP for Areas II and III and the proposed CUP for Area IV. It appears from Petitioners' Response to the other PROs that one purpose for their arguments that the proposed CUP for Area IV cannot be implemented before its expiration is to buttress their arguments, already addressed, that there is no need for the proposed CUP for Area IV. Priority Water Resource Caution Area Designation As part of its water supply planning process, the District designates priority water resource caution areas. A priority water resource caution area is an area where existing and reasonably anticipated sources of water and water conservation efforts may not be adequate to supply water for all existing legal uses and anticipated future needs and to sustain the water resources and related natural systems. The area surrounding the Area IV Wellfield was designated as a priority water resource caution area in the District’s 2003 Water Supply Assessment and 2005 Water Supply Plan based on groundwater modeling prepared by District planning staffing using the ECF and Volusia County Regional Models. The fact the Area IV Wellfield is located in a priority water use caution area does not mean a consumptive use permit cannot be issued for this facility. In fact, over one- third of the District is located within a priority water resource caution area, and permits continue to be issued in those areas. Rather, the essence of the designation is the recognition of a concern, based on the regional models, that the proposed consumptive use of water might violate the wetland and lake constraints and that water resources other than fresh groundwater will be needed to supply the expected need for water in the area and in the District over the next 20 years. That does not mean that no additional groundwater withdrawals should be permitted in a designated area. Rather, it means that other resources should be developed and used along with whatever remaining additional fresh groundwater can be permitted. It is not an independent reason, apart from the permitting criteria, to deny the City's application. Impermissible Modification of Existing CUP Petitioners contend that the proposed CUP for Area IV includes an impermissible modification of the existing CUP for Areas II and III because “Other Condition” 5 limits average annual withdrawals from the Area II, III, and IV Wellfields, combined, to 5.79 mgd in 2009 and 6.01 mgd in 2010. (As indicated, the limitations would have to be reduced to no more than 5.2 mgd based on the more reasonable projected need.) However, the City’s current CUP for the Area II and III Wellfields expires in February 2008, which is before the Area IV Wellfield would become operational, so that "Other Condition" 5 will have no practical effect on the existing CUP for Areas II and III. In essence, "Other Condition" 5 serves to advise the City that it should not view the allocation for the Area IV Wellfield in addition to the City’s existing allocations for the Area II and Area III Wellfields and that any renewal of the existing CUP for Areas II and III will have to take the Area IV allocation into account. Appropriate Permit Fee Petitioners have alleged that the City has not paid the correct permit processing fee. In March 2001, the City paid the District $200 when it submitted its initial permit application to modify its existing CUP. In May 2005, the City paid the District an additional $800 when it amended its application and withdrew its request to modify its existing permit. All required permit processing fees have been paid for this CUP application 99052. Miscellaneous As to other issues raised by Petitioners in the case, the evidence did not suggest any danger of flooding, any proposed use of water reserved by rule for other uses, any effect on any established minimum flows or levels, or inadequate notice. Standing As found, Miami Corporation owns property immediately adjacent to the proposed Area IV Wellfield, and Ms. Clark owns property a little more than a mile away. Both alleged and attempted to prove that SAS drawdown from the proposed CUP would degrade wetlands on their property and interfere with their legal use of groundwater, and that saline intrusion from the proposed CUP would degrade the water quality of the UFAS resource which they use for potable water. As found, Petitioners did not prove those allegations; however, the evidence was that both Petitioners have substantial interests (the quality of water in the aquifer from which their wells withdraw water and wetlands on their property) that would be affected by the proposed CUP at least to some extent.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the District issue the City a CUP for Area IV as provided in the second revised TSR, except for a lower water allocation at this time, namely: 0.75 mgd on an annual average basis, with appropriately lower allocations on the other bases in the TSR, and with a combined annual average rate for Areas II, III, and IV in "Other Condition" 5 of 5.2 mgd for 2009 and 2010 instead of 5.79 mgd in 2009 and 2010, and appropriately lower combined maximum daily rates for Areas II, III, and IV in "Other Condition" 9. Jurisdiction is reserved to hear and rule on the pending motions for sanctions if renewed no later than 30 days after entry of the final order in this case.

Findings Of Fact In approximately 1987, the Petitioner purchased land in Pinellas County, of which approximately 85 percent lies within jurisdictional wetlands. (The jurisdictional wetlands approximate the surface water mean high water line.) Some of the wetlands will have to be filled in order to construct a residential dwelling on the property. The nearest public sewer connection is over a mile away from the Petitioner's property. The only reasonable alternative for the treatment of residential sewerage is an onsite sewage treatment and disposal system. The only reasonable alternative for construction of an onsite sewage treatment and disposal system on the property would require a drainfield to be located well within 75 feet of the jurisdictional wetlands, which are surface waters of the State. In fact, the proposed drainfield would have to be as close as six to twelve feet from the jurisdictional wetlands in most places. In addition, there is a drainage ditch along the road on the western boundary of the Petitioner's property. The drainage ditch contains water for extended periods of time in the rainy summer months. The drainfield for the Petitioner's proposed onsite sewage treatment and disposal system would be approximately 21 feet from the drainage ditch. In other words, a 75 foot setback from the drainage ditch would overlap the 75 foot setback from the jurisdictional wetlands. Although the Petitioner's proposed onsite sewage treatment and disposal system is designed to function without failing during such conditions, parts of the drainfield can be expected to be inundated during the rainy season. In effect, as a result of rainfall and runoff during rainy weather, the water from the wetlands and the drainage ditch would be expected to overflow the jurisdictional line and the ditch banks and inundate parts of the drainfield. There would be a direct connection between the waters inundating the drainfield and the surface waters of the wetland and of the drainage ditch. The Petitioner proposes to have, and several neighbors have, potable water wells to supply drinking water. There are sinkholes all over the area of the Petitioner's property. It is not known whether there is a sinkhole on the Petitioner's property, but it is well known that sinkholes are common in cypress head swamps like the wetlands on the Petitioner's property. If there is a sinkhole, or if one develops, it could act as a direct conduit from the surface water to the aquifer from which the private drinking water wells in the area draw water. Contamination from the Petitioner's drainfield then would be able to contaminate the drinking water. Potential fecal coliform contamination of the surface waters adjacent to the Petitioner's proposed drainfield (both the wetlands and the drainage ditch) also could pose a public health threat. The County recently has disposed of digested sludge in the vicinity of the Petitioner's site (i.e., within approximately a mile away). (It is not clear from the evidence whether this still is taking place.) However, under applicable Department of Environmental Protection rules, the sludge was being applied to pasture at least 300 feet from cypress heads, and the County also was required to meet other environmental controls and regulations for that kind of disposal. The Petitioner's evidence did not prove that discharge from his proposed onsite sewage treatment and disposal system will not adversely affect the health of the Petitioner or the public or that it will not significantly degrade the groundwater or surface waters.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Department of Health and Rehabilitative Services (HRS) enter a final order denying the Petitioner's application for a variance.

Findings Of Fact Respondent/Applicant, North Orlando Water and Sewer Company, filed an application on August 11, 1981, with Respondent, Department of Environmental Regulation, seeking a permit to authorize the construction of sewage effluent disposal ponds in Winter Springs, Seminole County, Florida. On August 16, 1981, the Department advised the Applicant that additional information was required. This information was supplied by Applicant on September 11, 1981. After reviewing the application and supplemental information, the Department determined that Applicant had provided reasonable assurance that the proposed percolation ponds would not adversely affect waters of the State and thereafter issued Permit No. DC59-46435 on September 22, 1981, authorizing the construction of the requested activity. Petitioners are owners of the property on which one of the disposal ponds is to be constructed. On June 12, 1981, Applicant instituted condemnation proceedings in Circuit Court for Seminole County under Chapters 73, 74 and 361, Florida Statutes, seeking to condemn the property so that the facilities could be constructed. The suit remains pending until all necessary permits from the Department are acquired by Applicant. The parties agree that based on plans, test results and other information, the construction of the proposed installation will not discharge, emit, or cause pollution in contravention of Department standards, rules or regulations. The permit was issued without formal public notice. However, it falls under the class of permits enumerated in Rule 17-1.62(3)(a), Florida Administrative Code. That rule makes publication of a notice discretionary on the part of the Department, and no abuse of discretion was shown. Item D(i) on page 7 of the application requires that the Applicant "[i]ndicate the number of potable water supply wells within 500 feet of effluent disposal area, the depths of these wells and their approximate distances from the disposal area." Applicant answered "None". There are no public potable water supply wells within 500 feet of the effluent disposal area. There are several private potable water supply wells within 500 feet of the pond but adequate buffer zones between these private potable water supply wells and the actual effluent disposal area exist. Moreover, Petitioners' expert witness conceded that seepage would be minimal, should not be a concern, and the failure to list the private wells on the application had no effect on the substantive merits of the application. Applicant construed the term "potable water supply wells" to mean only public wells since DER has no jurisdiction over private wells. For this reason, it answered the question in the manner that it did. The Department concurs in this interpretation.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that Permit No. DC59-46435 be issued to Applicant, North Orlando Water and Sewer Company. DONE and ENTERED this 23rd day of July, 1982, in Tallahassee, Florida. DONALD R. ALEXANDER Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 23rd day of July, 1982.
Findings Of Fact On November 1, 1982, Respondent Janson filed a Joint Application for a dredge and fill permit from Respondent, Department of Environmental Regulation, and from the Department of the Army Corps of Engineers. The project described in that application involved the construction of an approximately 1,000-square- foot, pile-supported residence, landward of the mean high water line but within the landward extent of Robinson Creek in St. Johns County, Florida. The proposed project also involved the placement of approximately 35 cubic yards of fill and a 30-foot culvert within a small (approximately 4-foot), tidally- influenced roadside ditch for driveway access and parking. The original application sought permission to place part of a concrete driveway and tool shed within the landward extent of Robinson Creek. The project is to be constructed on Lot 47, J.A. Lew Subdivision. Respondent Janson owns Lot 47, as well as Lots 45 and 46, which lots are north of and adjoining Lot 47 and also adjoining Robinson Creek. The next adjoining property owner to the north is the City of St. Augustine, Florida, which presumably owns the street. The adjoining property owner to the south of Lot 47 is Virginia P. Melichar. Neither Melichar nor the City objected to the Department's approval of the dredge and fill permit application. In support of his application, Janson retained the services of a registered surveyor and civil engineer, who performed a survey on Lot 47 to determine the location of the mean high water line with reference to the proposed project. That expert determined the location of the mean high water line to be at elevation 2.4 feet. Accordingly, all work contemplated by the dredge and fill permit is upland from the mean high water line. T.J. Deuerling, an environmental specialist for Respondent, Department of Environmental Regulation, visited the project site on December 13, 1982 and on December 30, 1982 in order to prepare the Department's Biological and Water Quality Assessment. As a result of those site visits, Deuerling recommended to Respondent Janson that he modify his permit application by moving the concrete slab and tool shed from the marsh area onto the uplands. Janson did so revise his application. In spite of the name of the permit being sought by Respondent Janson, the project involves no dredging. However, the culvert and its attendant fill would be placed in the man-made roadside ditch. That ditch constitutes a very weak transitional marsh. Although the culvert will eliminate some vegetation within that ditch, the effect of the elimination will be insignificant on water quality. The pilings for the pile-supported residence will also eliminate a small area of marsh. The anticipated shading caused by the pile-supported residence may impact somewhat on the vegetation in a small area below the residence; however, due to the fact that the floor of the house will be eight feet above the ground, light will still be able to penetrate. Therefore, the vegetation below the pile-supported residence will continue to act as a filter for pollutants. Janson has mitigated the small loss in wetlands by modifying his project so as to remove the concrete slab and tool shed from the marsh area to the uplands. Due to the project's small size, no storm water impact can be expected. Additionally, no evidence was introduced to show a violation of any water quality standard as a result of the proposed project. On March 16, 1983, Respondent, Department of Environmental Regulation, executed its Intent to Issue the dredge and fill permit in accordance with the revised application and subject to the conditions that: (1) turbidity curtains be employed in the ditch during the placement of fill over the culvert to contain any turbidity generated, and (2) construction on the uplands be confined to periods of normal water level conditions. On July 5, 1983, the Department of the Army Corps of Engineers issued its Permit and Notice of Authorization. The essence of the testimony presented by the Petitioners, including that of the employees of the St. Johns River Water Management District, who testified in opposition to the proposed project, is that even though Janson's proposed project would not impact water quality in a way that was either significant or measurable (although no one even suggested any specific water quality standard that might be violated), approval of Janson's permit might set a precedent for other projects which might then have a cumulative impact in some unspecified way at some unspecified location. No evidence was offered to show that Respondent, Department of Environmental Regulation's review of permit applications is other than site specific. Further, no evidence was introduced to show any proposed project anywhere having any impact with which Janson's project could be cumulative. Petitioners Sandquist and Shuler live in the neighborhood of the proposed project, perhaps as close as two blocks away.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered dismissing with prejudice the petition filed herein as to each individual Petitioner and issuing a dredge and fill permit to Respondent Janson in accordance with his revised application.

The Issue The issue to be determined in this case is whether the proposed amendment to Florida Administrative Code Rule 62-555.360 of the Department of Environmental Protection (“Department”), pertaining to cross-connection control for public water systems, is an invalid exercise of delegated legislative authority.
Findings Of Fact The Parties Petitioner is a natural person residing at 1805 Burlington Circle, Sun City Center, Hillsborough County, Florida. The Department is the state agency with powers and duties to protect public drinking water as set forth in the Florida Safe Drinking Water Act, section 403.850, et seq., Florida Statutes (2013). Background The term “cross-connection” is defined in rule 62-550.200(26) as: any physical arrangement whereby a public water supply is connected, directly or indirectly, with any other water supply system, sewer, drain, conduit, pool, storage reservoir, plumbing fixture, or other device which contains or may contain contaminated water, sewage or other waste, or liquid of unknown or unsafe quality which may be capable of imparting contamination to the public water supply as the result of backflow. Cross-connections are prohibited unless appropriate backflow protection is provided to prevent backflow through the cross-connection into the public water system. See Fla. Admin. Code R. 62-550.360(1). There are three types of backflow prevention devices germane to this proceeding: Reduced Pressure Principle Assembly ("RP"), Double Check Valve Assembly ("DC"), and Dual Check Device ("DuC”). Typically, but not in every case, the water customer is responsible for the costs of installation, inspection, and maintenance of a backflow prevention device. It is undisputed that the RP is the most expensive to purchase, install, and maintain; followed by the DC; and then the DuC.2/ The RP and DC are installed above-ground, usually near a street. Test ports on these assemblies allow them to be tested to determine whether they are still functioning to prevent backflow. The DuC is usually installed underground and has no test ports. The Department asserts that this difference makes the DuC less reliable than the RP and DC. The rule states, and Petitioner did not refute, that the RP and DC offer greater backflow protection than the DuC. Petitioner has an auxiliary water system at his residence, which he uses to pump untreated water from a nearby lake to irrigate his lawn. There is no cross-connection between the plumbing system in Petitioner’s residence and his auxiliary water system. Petitioner does not have a backflow prevention device installed at his property. Hillsborough County has an ordinance that requires the installation of an RP device for residential customers who have auxiliary water systems, but the County currently has a moratorium on the enforcement of its ordinance. Petitioner is on a local committee established to investigate and advise the Hillsborough County Board of County Commissioners regarding cross-connection control. He believes the County is likely to modify its ordinance and allow the DuC for residential customers who have auxiliary water systems. The Department Rule The Department stated its purposes for the rule in the Notice of Proposed Rulemaking: These rules are being amended to significantly reduce the overall regulatory burden of cross-connection control requirements on community water systems (CWSs) and their residential customers by: allowing a dual check device to be used as backflow protection at or for residential service connections from CWSs to premises where there is any type of auxiliary or reclaimed water system; and (2) allowing biennial instead of annual testing of backflow preventer assemblies required at or for residential service connections from CWSs. A community water system (“CWS”) is a public water system which serves at least 15 service connections or regularly serves at least 25 year-round residents. See § 403.852(3), Fla. Stat. The Department requires each CWS to have a cross- connection control program, and Table 62-555.360-2 in the rule establishes the “Minimum Backflow Protection” that must be provided at or for the service connection from the CWS to various types of water customers. The minimum backflow protection specified in the table for a residential service connection with an auxiliary water system is a DuC. All references hereafter to “residential service connection” shall mean one with an auxiliary water system. There is a footnote for the DuC at the bottom of the table, which explains: A DuC may be provided only if there is no known cross-connection between the plumbing system and the auxiliary or reclaimed water system on the customer's premises. Upon discovery of any cross•connection between the plumbing system and any reclaimed water system on the customer's premises, the CWS shall ensure that the cross-connection is eliminated. Upon discovery of any cross- connection between the plumbing system and any auxiliary water system other than a reclaimed water system on the customer's premises, the CWS shall ensure that the cross-connection is eliminated or shall ensure that the backflow protection provided at or for the service connection is equal to that required at or for a non•residential service connection. The SERC As part of the rulemaking process for the proposed amendments to rule 62-555.360, the Department prepared a Statement of Estimated Regulatory Cost ("SERC"). Section 120.541, Florida Statutes (2013), governs the preparation of SERCs and provides that a substantially affected person may submit a “good faith written proposal for a lower cost regulatory alternative that substantially accomplishes the objectives of the law being implemented.” See § 120.541(1)(a), Fla. Stat. The parties dispute whether Petitioner challenged the SERC. In his amended petition, Petitioner states no objection to any statement in the SERC. Petitioner did not challenge the SERC. The parties dispute whether Petitioner submitted a lower cost regulatory alternative. The Notice of Proposed Rulemaking stated: Any person who wishes to provide information regarding a statement of estimated regulatory costs or provide a proposal for a lower cost regulatory alternative must do so in writing within 21 days of this notice. Within 21 days of the notice, the Department received Petitioner's written comments. In his comments, Petitioner cites section 120.52(8)(f), which provides that a rule is invalid if it imposes regulatory costs which could be reduced by adopting a less costly alternative. Petitioner recommends that the rule be changed to specify that the less costly DuC is the only acceptable backflow prevention device for residential service connections and “A CWS shall not impose a requirement for a more expensive type of backflow prevention valve.” The Department contends that Petitioner’s comments did not constitute a good faith lower cost regulatory alternative, citing pages 87-98 of the Transcript. Those pages contain some argument on the issue, but do not prove Petitioner did not submit a lower cost regulatory alternative. Petitioner’s timely written comments included a citation to the relevant statute and a plainly-worded proposal. As explained in the Conclusions of Law, Petitioner’s comments were sufficient to constitute a lower cost regulatory alternative. Petitioner’s Objections Petitioner objects to rule 62-555.360 because (1) it specifies use of the RP and DC, which he contends are unreasonably dangerous to public health and safety; (2) it specifies the DuC for residential service connections as the “minimum” protection, which he contends allows a CWS to require the more expensive RP or DC; (3) it requires testing of backflow devices “at least biennially” (once every two years), which he believes is too frequent; (4) it makes biennial testing a “minimum” testing interval, which he contends allows a CWS to require more frequent inspection; and (5) it does not require the backflow prevention device to be attached to the CWS’s water meter where Petitioner believes it should always be located. Unreasonable Danger Petitioner contends that the RP and DC are unreasonably dangerous to public health and safety because a person could intentionally pump contaminants through a test port on one of these assemblies into a public water supply. The Department does not dispute that a person could introduce contaminants into a public water supply in this way. The flaw in Petitioner’s reasoning is his failure to see the danger in proper perspective. Department personnel and other persons with expertise in public water systems throughout the United States are well aware that there are many access points in potable water collection, treatment, and distribution systems and many methods to introduce contaminants into these systems. There are many access points other than RPs and DCs. For example, there are methods available that would allow contaminants to be pumped into a public water system from any building connected to the system that has no backflow prevention device installed. RPs and DCs are primarily designed to prevent accidental introduction of contaminants into a public water system. However, they also prevent a person from intentionally pumping contaminants into the public water system from inside a house or building, hidden from view. The danger described by Petitioner assumes that the criminal who is intentionally pumping contaminants through the RP or DC will do it while standing next to the device, in the open, near a street. It is a well-known fact officially recognized by the Administrative Law Judge that criminals prefer to conduct their criminal activities hidden from sight rather than in plain view. Therefore, a criminal planning to contaminate a public water supply is more likely to choose a means other than introducing contaminants through an RP or DC. RPs and DCs are already in wide use. There is no reported incident of intentional contamination of a public water supply by pumping contaminants through one of these devices. When these factors are taken into account, the rule’s specifications for the continued use of RPs and DCs do not create an unreasonable danger to the public health and safety. Minimum Backflow Protection Petitioner contends that Table 62-555.360-2 is invalid because it violates the Department’s duty under section 120.541 to adopt “less costly alternatives.” Petitioner asserts that by specifying the DuC as the “minimum” backflow protection required for residential service connections the rule allows a local government to require the more costly RP or DC. The Department cannot dispute that the DuC substantially accomplishes the statutory objectives. The RP and DC provide greater backflow protection than the DuC, but the Department specified the DuC for residential service connections, indicating that the lower protection provided by the DuC did not make it fall short of the statutory objectives. However, as explained in the Conclusions of Law, the rule imposes the least costly regulatory alternative for residential service connections because it only requires the DuC. Biennial Testing Schedule Petitioner contends that section III.D. of Table 62-555.360-1 also violates the Department’s duty to adopt less costly alternatives because the rule requires “backflow assemblies” to be tested biennially, which Petitioner believes is too frequent. The term “backflow preventer assemblies” refers only to the RP and DC. See footnote 1 of Table 62-555.360-1. Section III.E. of Table 62-555.360-1 indicates that the DuC must be refurbished or replaced “at least once every 5 to 10 years.” Petitioner did not object to this requirement. The preponderance of the evidence presented shows that biennial testing is reasonable. Furthermore, it is determined in the Conclusions of Law that Petitioner has no standing to object to the testing frequency specified for the RP and DC, because the rule does not require him to have an RP or DC. Location of the Backflow Preventer Petitioner objects to section III.B. of Table 62-555.360-1, which requires backflow prevention devices to be “installed as close as practical to the CWS’s meter or customer’s property line.” Petitioner contends that this is an unconstitutional interference with private property and is unreasonably dangerous because it provides a means for intentional contamination. Petitioner’s private property rights claim is based on his allegation that if he were required by Hillsborough County to have an RP and DC, the device could be placed on his private property. Petitioner did not allege or present evidence to show that placing an RP or DC on his property would deprive him of all reasonable uses of his property so as to cause a taking of his private property for a public purpose without full compensation. See Art. X, § 6(a), Fla. Const. Furthermore, it is determined in the Conclusions of Law that Petitioner has no standing to raise this issue because the rule does not require him to have an RP or DC. Petitioner contends the rule should require that backflow prevention devices always be attached to the water meter because that reduces the opportunity for intentional contamination. Petitioner is not an expert in public water systems, generally, or the installation of backflow prevention devices, in particular. He is not competent to state the relevant factors and constraints associated with installation of the devices. He is not competent to express an opinion whether it is always possible or always appropriate to attach the devices directly to the water meter. Furthermore, Petitioner’s claim of unreasonable danger was refuted above.
Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, as well as the stipulation of facts contained in the Prehearing Stipulation, the following relevant facts are found: The Gardinier Applications. l. The East Tampa Chemical Plant (plant) operated by Gardinier is located on approximately 3,500 acres of land owned by it at the mouth of the Alafia River and the Hillsborough Bay. The facilities have been there since 1924, and the withdrawal of water utilized to operate the plane predates the consumptive use permitting process. The plant manufactures various fertilizer products, including sulphuric acid, phosphoric acid, diammonium phosphate, granular triple superphosphate, run of pile triple superphosphate, byproducts of phosphoric acid, as well as fluosilic acid and sodium silicofluoride. The phosphoric acid products are used by farmers to grow corn, soy beans, and wheat, and fluosilic acid and sodium silicofluoride are used by municipalities to fluorinate drinking water. When the plant is fully operating, Gardinier employs 950 people with a payroll of $22 million a year. The company pays annual property and other taxes of $1.5 million a year and annually purchases approximately $25 million in materials and equipment in Hillsborough County. Garciinier was recently purchased by Cargill, Inc. after a bankruptcy proceeding. In order to manufacture its products and operate the plant, Gardinier uses both salt water and fresh water. The salt water comes from salt water wells located on the plant's property, and has been used since 1924 for cooling purposes. It is used for once-through, non-contact cooling of sulphuric acid and is then discharged into the Alafia River at the Hillsborough Bay. Due to the naturally occurring radium in this discharged salt water, Gardinier intends to discontinue using its salt water wells and utilize fresh water for all its cooling requirements. This will require the construction of a fresh water cooling tower, for which a permit is currently being sought and which will take about two years to complete. Gardinier's existing CUP No. 7601530 for its salt water wells permits an average annual withdrawal of 56,260,000 gallons of water per day (gpd) and a maximum daily withdrawal of 64,890,000 gpd. Despite expansions in its plant over the years, the amounts of salt water and fresh water required has decreased. Gardinier's present renewal application for its salt water withdrawals proposes a reduction to an average annual rate and maximum daily rate of 31,968,000 gpd . Fresh water is used at Gardinier's plant as boiler feed water, for manufacturing of product or process water, cooling and potable needs. This water is obtained from Buckhorn Springs and Lithia Sprlngs, both wholly owned by Gardinier. Gardinier purchased 148 acres at Buckhorn Springs in 1947, and 160 acres at Lithia Springs in 1967, including the spring pools, and has been withdrawing water from those springs since those times. Lithia Springs is leased to Hillsborough County for recreational purposes. Gardinier's withdrawals from the springs have been gradually reduced since 1977. The original CUP No. 7601532 issued in 1977 for Buckhorn Springs authorized an annual average withdrawal of 2,176,000 gpd with a maximum daily withdrawal not to exceed 2,370,800 gpd. Gardinier requested a reduced withdrawal s renewal application, with an annual average and a maximum daily rate of 1,440,000 gpd. Gardinier's original CUP No. 7601533 for Lithia Springs issued in 1977 was for 5,840,700 gpd average annual withdrawal and 5,894.000 gpd as a maximum daily withdrawal. Gardinier's renewal is for a reduced average withdrawal rate of 5,822,000 gpd and a maximum daily withdrawal of 5,904,000 gpd. The increased maximum quantity is for the well used for the concession stand at the park. Withdrawals from Gardinier's salt water wells consists of comingled waters from the intermediate aquifer, the Floridan aquifer and Hillsborough Bay. The water is salty, high in chloride and its constituents are very similar to bay water. The evidence is inconclusive as to whether Gardinier's operation of its salt water wells for a period of over 60 years has caused or contributed to salt water intrusion in thc area of the plant. There is some evidence that the pumping may have been beneficial in reducing salt water encroachment along the coast due to the release of pressure on the deeper Floridan aquifer which allows fresh water to move into the system. In any event, if there has been an adverse effect from more than 60 years of pumping, the effect would be reduced by the reduction in withdrawals which Gardinier now seeks in its permit renewals. While Gardinier is the largest use of water in the plant area, there are domestic wells in the vicinity of the plant. Computer modeling demonstrates that present withdrawals from the salt water wells will affect the potentiometric surface at the plant's boundary by less than five feet and create less than a one-foot drawdown in the water table. The greater portion of the water pumped is recharge water from the bay. Any reduction in the amount of pumping would have a positive impact on the potentiometric surface, will decrease any impact on nearby domestic wells and will allow the quality of the water in domestic wells to either remain stable or improve. Since the potentiometric surface in the plant's vicinity is already at sea level, it is SWFWMD's policy not to take into account the regulatory criterion relating to the lowering of the potentiometric surface below sea level. SWFWMD has not established regulatory levels for the rate of flow of streams or watercourses, the potentiometric surface or surface waters in the vicinity of the plant. Salt water marshes, estuarine systems and uplands exist to the north, south and east of the plant. Any adverse ecological impact suffered by these systems are more attributable to cultural impacts than to a less than one foot lowering of the water table. Since Gardinier's withdrawals have been occurring for over 60 years, it is likely that biological communities in the area have adapted, and the proposed reduction in pumping have no additional adverse effect. In order to satisfy its requirements for fresh water of reliable quantity and quality, Gardinier has been withdrawing water from Buckhorn Springs for almost 40 years and Lithia Springs for almost 20 years. The boilers and cooling towers at the plant are designed to utilize water of that quality and temperature. But for Gardinier's withdrawals, these spring waters would flow into the Alafia River and eventually into the bay. The spring water from Lithia is pumped through a pipeline to Buckhorn Springs, comingles with the Buckhorn spring water and is pumped some 1< miles through a pipeline to the chemical plant for use as boiler feed water, process water, cooling water and sanitary and drinking water. During full production periods, Gardinier uses all the water withdrawn from Lithia and Buckhorn Springs. Because of cutbacks in production in 1983, Gardinier installed a pressure relief valve to alleviate pressure problems in the plant during times of reduced production. This allowed water to be discharged into the Alafia River from the Lithia pipeline without passing through the plant. Over the past two years, approximately .5 to 1.2 million gallons of water per day has passed through the pressure relief valve and discharged in the Alafia River at a point downstream from where it would have entered the river naturally. Gardinier is presently in the process of developing an alternative pressure control system which would permit it to take from Lithia and Buckhorn Springs only the amounts actually required at the plant. Lithia Springs and Buckhorn Springs are typical karst artisian sink springs. The geology and hydrogeology of the area of both springs demonstrates a series of fault features, where solid rock has fractured and the fractures extend into the Floridan aquifer. Solutioning occurs and a sinkhole system is created. The springs are discharge points of the Floridan aquifer. These aquifer waters discharge into the springs from artisian pressure. An examination of various well logs and literature on Florida geology leads to the conclusion that the water in Lithia Springs and Buckhorn Springs withdrawn by Gardinier are supplied primarily by the Floridan aquifer with very minimal contribution from the intermediate or surficial aquifers. The withdrawals at both springs constitute ground water, as opposed to surface water, withdrawals. As noted above, Gardinier owns 148 acres at Buckhorn Springs and 160 acres at Lithia Springs. There are 350 feet from the edge of Buckhorn Springs to the nearest property line and 400 feet from the edge of Lithia Springs to the nearest property line. Pump tests designed to determine the lateral and vertical extent of the impact from the stress of pumping in amounts far greater than usual demonstrate that the impacts from withdrawals do not extend beyond 300 feet from the edge of either spring. After stabilizing the springs and pumping at a greater rate than normal, the pump tests revealed only a 1.25 foot decline in the spring boil, a 1.06 foot decline in the spring pool and no appreciable change in the water table or surface water at Buckhorn Springs. The impacts from pumping at Lithia Springs were even more minimal -- a two inch decline in the water level of the spring boil and a decline in the pool level of less than one inch. These results lead to the conclusion that the artisian systems are not adversely affected by Cardinier's pumping at Buckhorn or Lithia Springs. Chemical analyses reveals that the quality of the waters at Buckhorn and Lithia Springs has not been adversely affected by Cardinler's pumping or withdrawals. The proposed withdrawals will have no adverse effect upon vegetation in the areas of Lithla or Buckhorn Springs. There will be no inducement of salt water encroachment as a result of Gardinier's withdrawals from Lithia or Buckhorn Springs. SWFWMD has set no regulatory levels pertaining to the rate of flow of streams or watercourses, the level of the potentiometric surface or the level of surface waters in the areas of Buckhorn or Lithia Springs. It is the policy of the SWFWMD not to require extensive testing or monitoring when an applicant is applying for a renewal of a presently existing legal use, particularly when the renewal is for a permit with reduced quantities. In order to determine the future adequacy of the water supply available from Lithia and Buckhorn Springs, as well as to determine the effect of a diminuition of the outflow by outside sources, it would be beneficial to place continuous recording gases on spring flow, spring height and pumpage at those spring sites. Many industries are capable of and do now utilize reclaimed, recovered or recycled water in their plant operations. Dependent upon the plant's equipment and ;he quantity and quality of the reuse or recycled water, such water can be utilized in chemical plant operations for such nonpotable uses as cooling water, boiler feed and process water. A source of reuse water is treated effluent from advanced wastewater treatment facilities. Several new County wastewater treatment plants are presently in the planning stage, but none are currently on line nor are there pipelines in existence which could supply reuse water to Gardinier's East Tampa Chemical Plant. Use of the existing pipeline for reclaimed or reuse water would contaminate Gardinier's existing fresh water supply from the springs. Considering the quantity and quality of its present source of fresh water, reuse water has no technical or economic advantage to Gardinier. Its plant equipment would have to be retrofitted, a new distribution system both within and outside the plant would be required and experience by other industrial users has demonstrated problems with scaling, increased temperature and the consistency of water quality. When weighing the potential for reuse water in plant operations, a large factor to be considered is the economic feasibility, including the cost of treatment, maintenance costs, the cost of the current supply, availability, etc. While the reuse of water should be encouraged as a conservation measure, the economic feasibility of such use must be considered. Gardinier has studied and has agreed to continue to study the feasibility, both technical and economical, of reuse water for some of the plant operations. The Authority's and County's Application. The Authority is a five member governmental entity consisting of Pasco County, Pinellas County, Hillsborough County, the City of Tampa, and the City of St. Petersburg. Its obligations are to provide an adequate and dependable source of supply for all citizens within the tri-county area and to do so without concentrating withdrawals to the point where they would have an adverse environmental or hydrological impact. The Authority first began operating public supply wellfields in 1978. Currently, the Authority operates the Cypress Creek Wellfield, the Cross Bar Ranch Wellfield, the Starkey Wellfield, the Section 21 Wellfield, the Cosme-Odessa Wellfield, and the Northwest Hillsborough Wellfield. The permitted average annual withdrawal rate and maximum daily withdrawal of these wellfields are 30 million gallons per day (mgd)/30 mod for Cypress Creek, 30 mgdt45 mgd for Cross Bar, 8 mgd/15 mgd for Starkey, 13 mgd/22 mgd for Section 21 and Cosme-Odessa and 8.8 mgd/18.q mgd for the Northwest Hillsborough Wellfield. In addition, the Authority has a consumptive use permit to withdraw water from the Tampa Bypass Canal at a rate of 20 mgd average annual withdrawal and 40 mgd maximum daily withdrawal. The south central Hillsborough County region and service area has been described in this proceeding as an area bounded by Interstate ~ on the north, by Valrico on the east, by the Little Manatee River on the south and by Tampa Bay on the west. The area is largely a rural area, but has several population centers, including Brandon, Ruskin, Apollo Beach, Sun City and Riverview. The County's current public water supply facilities in the south central region comprise some 75 dispersed wells permitted under 8 different CUPs. The evidence is conflicting and inconclusive as to the actual number of existing wells and the quantities presently permitted. Some of the presently permitted wells have been converted to monitoring wells and others have been plugged. The Authority and the County have concluded that it is no longer possible to continue to use the County's existing public water supply facilities in the south central area. Consequently, they have applied for a CUP which would renew and consolidate their existing 8 CUPs and add 17 new wells to be located at a regional wellfield. It is the intent of the Authority and the County to continue using the existing wells during construction of the planned wellfield and then to discontinue their use and serve the entire area from a centralized wellfield. The amended application requests total average annual combined permit withdrawals of 24,100,000 gpd and total maximum daily withdrawals of 44,600,000 gpd. The current, existing Brandon water supply system is comprised of some 30 dispersed wells capable of producing from 7 to 10 mgd of good quality water. However, there are problems in this system, as well as the smaller systems serving Sun City, Apollo Beach, Ruskin and Riverview. The Brandon wells have individual chlorinators and, on occasion, suffer pressure problems. Because of their dispersed locations, the County's operators can only visit each well site once a day. If a problem occurs after the operator's visit, it will not be discovered until the following day and recipients of the water may use water that has not been disinfected. It is difficult to monitor and sample the well waters due to their dispersed locations. The existing system relies totally on local wells for local distribution as there is a complete lack of transmission facilities. The systems are hydraulically isolated and there is no transmission capacity within the Brandon system at all. While there is one intertie with the City of Tampa's water system, this is not used primarily because the City has its own supply problems and also because the City's water treatment is different than and incompatible with the County's water treatment. Some of the existing wells located south of the Alafia Rlver are old, in poor repair and violate Florida's drinking water standards for total dissolved solids, sulfates, fecal coliform and occasionally odor. Many of the existing well sites are not secured and their locations are such as to constrain access to the larger repair equipment. The existing system has inadequate storage capacity. On the basis of present demand for water within the system, there should be at least 10 million gallons of available storage. The current storage capacity is slightly more than 4 million gallons and not all of this storage is available. A storage tank is generally kept at least half full to provide for local fire demand and, therefore, the effective storage capacity of the existing system is about 2 to 3 million gallons. The existing water supply system lacks the capacity for both adequate fire protection and adequate emergency pumping. Retrofitting or refurbishing the existing system with newer or more dispersed wells would simply perpetuate the existing inadequacies in the system. For these reasons, the Authority and the County have determined that the only feasible alternative to solve the inadequacies and to meet the current and future demand is to provide a centralized system of transmission lines, centralized master pumping facilities and a centralized source of water supply. As the wellfield production wells, pump station and transmission lines are constructed and become operational, the existing wells will be either taken out of service or will be utilized as monitor wells. It is estimated that the construction of the proposed wellfield will take from 18 to 24 months. In reaching a determination as to the location and design of the proposed south central wellfield, the Authority and the County analyzed various alternatives. Studies and testing were done regarding the placement of a regional wellfield in the Brandon area. However, testing demonstrated that the potential yield would be very low in that area and could cause the upconing of highly mineralized water. Tests conducted further to the east, in the Medard area, demonstrated a productive aquifer with good water quality. However, because large amounts of water are withdrawn from that area by strawberry farmers, particularly during freezing weather, that site was found unsuitable for a regional wellfield. The Authority also investigated the feasibility of creating a surface water supply and constructing reverse osmosis plants. These alternatives were rejected due to concerns regarding economics, adverse environmental impacts and the production of sufficient yield. Testing performed at the Lithia site resulted in findings that the aquifer was productive and had a good quality of water. To confirm these findings, further testing was done to the east of the Lithia site at Alderman's Ford Park. This testing resulted in a finding of a high yield of water that met drinking water standards. While traces of a volatile organic compound were revealed, these were determined to have resulted from the laboratory cleaning process. Thus, the Alafia River corridor was determined to be the appropriate location for a regional wellfield because it would not compete with the agricultural irrigation to the north, would avoid the poorer water quality to the south and would produce an adequate yield. The Authority and the County have completed the preliminary design of the proposed wellfield. It is to consist of 17 production wells and a pump station. Wells 1 and 2 are to be used as standby wells and pumpage is to be rotated among wells 3 through 17 so that withdrawals are evenly distributed among those wells. The standby wells are only to be used if there is a failure at another well within the wellfield. Well 1 is already constructed and is located about 1 1/2 miles from Lithia Springs on 80 acres of land purchased by the County for the master pump station. Well 1 is located about 100 feet from the nearest property boundary to the south. The remaining wells would be placed on one-acre well sites to be purchased by the applicant and located somewhere within the 40 acre quarter-quarter sections which the authority submitted to the SWFWMD as proposed well locations. The total additional land area to be acquired for the well sites is 14 acres. Two of the wells will be located on land already owned by the County. Some of the wells are concentrated, with three in one section. The Authority has attempted to locate the wells adjacent to road right-of-ways which could be used for transmission pipelines. The Authority has not yet developed a management plan or a monitoring plan for the proposed wellfield. Each of the wells within the regional wellfield is designed to pump at an average annual withdrawal rate of 3 mgd and a maximum withdrawal rate of 4 mgd. If only one well were turned on in the system and no other wells were running, the well would produce 4 mgd. However, with all of the other wells running, a single well would only produce 3 mgd due to friction loss and the energy required to pump a large mass of water through the pipe under greater pressure. Thus, while the wellfield would be able mechanically to pump 60 mgd, the optimum production capacity will be 45 mgd. On an average day, pumping will be rotated among a small number of wells to produce a total of 24.1 mgd. On a peak day, all 15 wells would be producing approximately 3 mgd each for a total combined withdrawal rate of 44.6 mgd. Based upon a per capita consumption of 189 gpd, it is estimated that the total water supply requirements for the south central service area in the year 1990 to meet average day and maximum day demands is approximately 24 mgd and 44 mgd, respectively. The proposed wellfield is located along the north and south prongs of the Alafia River. That area is characterized by rural and light agricultural land uses, residential areas and recreational sites. Land uses in the area have been dependent upon private, individual water wells, many of which are shallow and draw water from an intermediate aquifer. One proposed well site has 31 property owners within 1/2 mile of the well. One hundred property owners live within 1/2 mile of proposed well 17. These domestic well users will not be served by the proposed system. The Authority has issued revenue bonds to finance the construction of the regional wellfield and transmission lines. The regional wellfield will cost approximately $14,000,000 and the transmission lines will cost approximately S19.000,000. An additional S2,000,000 will be needed to complete construct on and these funds will be raised through the rate structure. In order to determine the proposed wellfield's impacts upon the potentiometric surface, water table and lake stages, the parties in this proceeding utilized information gathered from literature, pump tests, computer modeling and hand-calculated modeling to predict the drawdowns expected during periods of average and maximum pumping. While the actual numerical drawdown 1evels anticipated vary greatly among the expert witnesses presented, it is clear that the wellfield withdrawals, after pumping for 30 days at 24 mgd, will lower the potentiometric surface by more than 5 feet at the boundary of a one-acre well site and that the 5-foot drawdown contour will extend at least 2 1/2 miles radially around the center of the wellfield . The water table level will not be lowered more than three feet at the boundaries of the one-acre tracts, surface waters of lakes and impoundments will not be lowered more than one foot, and the potentiometric surface will not be lowered below sea level. Withdrawals from the wellfield will not induce salt water encroachment. When utilizing computer modeling to predict the impacts from withdrawals, it is essential to understand the site-specific geology and aquifer characteristics of the area. After studying the literature on the area of the wellfield, examining well logs and geophysical logs and conducting a well inventory in a 5-mile area across the wellfield, Gardinier's hydrogeologlsts found the area to be nonisotroptc and calibrated their modeling to account for the changes in geology throughout the area. The area of 'he proposed wellfield was fond to contain a thick clay confining layer which allows less water to permeate it. Inasmuch as less water moves through the layers to recharge the aquifer, the cone depression created by withdrawals from the wellfield extends over a larger and deeper area. Utilizing a value for leakance (defined as the vertical permeability through which water flows from the upper aquifer through a confining layer into the lower aquifer) of 1 x 104. Gardinier's experts predict that the potentiometric surface drawdown at Lithla Springs when the wellfield is pumping 24 mgd for 30 days will be about one foot under normal conditions. During a drought, the drawdown in the Floridan aquifer at Lithia Springs could be as much as 18.9 feet. The effects would, of course, be greater during pumpage rates of 45 mgd. During drought conditions, and possibly also when the wellfield is operating at maximum withdrawal rates, Gardinier may well have difficulty pumping water from Lithia Springs in the amounts for which it is seeking a permit. Various methodologies demonstrate that the potentiometric surface drawdown in the center of the proposed wellfield will be from 20 to 6G feet, depending upon the pumpage amounts and seasonal conditions. Such drawdown levels can interfere with existing wells in the area. Also, a lowering of the potentiometric surface could potentially lead to catastrophic collapse or subsidence in the area of the wellfield. The area is karstic in nature, with solution features such as sin);holes and springs present. Rapid ground collapses can occur in such areas due to a loss in the bearing strength of the unconsolidated material that fills the solution features. Such collapses have been associated with large withdrawals of water from pumping, thus creating extensive drawdowns, followed by a heavy rain. because of the particular geologic and aquifer characteristics of the wellfield area and the potential for interference with existing users, there should be a controlled maximum amount of water development in this area, along with observation wells and extensive monitoring of the various aquifer systems. In order to justify an exception to the District's rule that withdrawals not lower the level of the potentiometric surface more than five feet, the Authority proposes a mitigation program which it utilizes in other wellfields operated by it. This after-the-fact mitigation program consists of receiving complaints, sending a field representative to conduct an on-site investigation to determine the nature and cause of the problem, and sending a letter to the complainant and to SWFWMD documenting the results of the investigation. If the .authority determines that its wellfield operation caused the problem, if it takes mitigative action, such as reimbursing the complainant, hiring a contractor to solve the problem, or refurbishing or replacing the complainant's well or pumping equipment. The Authority also proposes various alternative mitigative actions if the wellfield affects Gardinier's ability to withdraw a sufficient quantity of water from Lithia Springs. These include the construction of new wells at Lithia Springs or along Gardinier's transmission pipeline, lowering the intake system at the springs and supplying Gardinier with water from the wellfield on an emergency basis. These suggested alternatives have not been fully investigated with regard to the effect upon the springs and fail to take into account the economic repercussions to Gardinier should it be unable to supply fresh water for the plant's operation while the Authority is investigating the problem and/or implementing the solution. The SWFWMD has proposed a before-the-fact mitigation plan for landowners living within one-half mile of each well site. This preventative mitigation plan would require the Authority to conduct a detailed water well inventory of all property owners located within one-half mile of the withdrawal point of each production well when the sites are finally selected. The Authority is to review each well's depth, casing size and depth, pump type and depth and the static water level, and then determine whether each well will be adversely affected with regard to its intended use. If so, the Authority is to commence its mitigative actions prior to or during construction of its production well. If an adverse effect is determined during testing of any production well, the Authority is to commence mitigative action prior to withdrawing water for public supply. The mitigative actions for impacted wells are to include well deepening, lowering or replacement of pumping facilities or whatever action is required to maintain an adequate water supply. The five-foot potentiometric surface drawdown contour extends beyond one-half mile during certain scenarios of pumping or seasonal conditions. The .Authority has been operating Well 1 as a test well under a temporary CUP, and has received six complaints from private well owners in the vicinity regarding water levels. No corrective action has been taken with regard to these complaints. With the exception of some phosphate mining cuts and small farm ponds, there are no significant lakes or other impoundments in the area of the proposed wellfield. It is anticipated that such water bodies will be affected by less than one foot by withdrawals from the wellfield. The greatest water table drawdown predicted is 2.8 feet at the center of the wellfield, where there are no open bodies of water. The area is culturally impacted now and is not ecologically sensitive. Vegetative species in the area are able to adapt to a wide range of soil moisture situations, and a less than one-foot reduction in the water table should not adversely or significantly affect vegetation in the area. Operation of the proposed wellfield at the requested rates of withdrawal will have no effect upon Buckhorn Springs or the East Tampa Chemical Plant. Intervenor Hebbard's private well is located between Well l in the proposed wellfield and Lithia Springs. He is concerned that the proposed wellfield will adversely affect land values in the area and the quantity and quality of his water withdrawals. He is also concerned with the potential for terrorist activity in a centralized water supply source and feels that the location of the proposed wellfield will not benefit existing Florida residents. The Lithia-Pinecrest Civic Association is not incorporated and has no membership list or bylaws. Its 47 years, uses the Alafia River for fishing and boating and is that the proposed wellfield will adversely affect his well and pumping facilities without adequate or timely mitigation and that the wellfield will remove the very resource for which the area is zoned: to wit: agicultural. Intervenor A. H. Varnum resides in the area of the proposed wellfield and also operates his business, Central Maintenance and Welding, Inc, in that area. He is concerned that the wellfield will adversely affect his water supply without sufficient mitigation. He is further concerned about the social impact of permitting a wellfield in this area when the water withdrawn will not benefit the persons who reside there. Intervenor I. A. Albritton was in attendance throughout the hearing. He was born in the area and now resides near Wel1 He has noticed odors, ground vibrations and decreasing water levels when Well 1 is pumping. He is concerned with dropping water table levels and the general condition of the land in the area.

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. DONE and ENTERED this 9th day of November, 1976, in Tallahassee, Florida. THOMAS C.

The Issue The issues in this case essentially are whether the Respondent, the Department of Environmental Regulation (DER), should reimburse Anthony F. Kopp, Owner, La Casa Del Sol, for the difference between the cost to him of the DER's remedy for the EDB contamination of the drinking water supply at La Casa Del Sol and the remedy that is least costly to the Petitioner, together with the cost of a new irrigation system, engineering and attorney fees, and other incidental costs to the Petitioner.
Findings Of Fact The Petitioner, Anthony F. Kopp, is the owner of La Casa Del Sol (La Casa), a 40-acre development at 1255 U.S. Highway 27 North, Davenport, Florida. La Casa is divided into 309 mobile home lots, a clubhouse and five acres of common green space. In January, 1987, the Petitioner received a permit for construction of a water supply system for both drinking water and irrigation needs at La Casa. The construction permit was granted with the proviso that, when La Casa's population reached 350, a second backup drinking water well, six inches in diameter at 410 feet, with a casing to 366 feet, and an auxiliary power source would have to be installed. It would cost La Casa approximately $65,000 to install the backup well and auxiliary power source. La Casa did not reach a population of 350 until January, 1991. The St. Johns River Water Management District permitted the construction of the backup well, but the well never was constructed, and the construction permit now has expired. The auxiliary power source also was not installed. The main water supply system for La Casa was installed during the summer of 1987. It included a well and a system of lines for carrying water to each of the 309 lots. It also included hose bibs (faucets) at each lot so that the water also could be used for irrigation at each lot. The system also supplied water for irrigation of the common green space. Although all of the lots at La Casa were connected to the water supply system in the manner described, not all the lots had homes on them. During the summer of 1989, only about 175 of the lots had homes on them; by January, 1991, 198 lots had homes on them. Although not all of the lots were occupied, the entire water supply system was permitted, and no additional permits were required to provide water to the lots. However, when La Casa's population reached 350, the backup well and auxiliary power source would have to be installed under the permit conditions. In about May, 1988, DER tests showed that the La Casa water supply system was contaminated with ethylene dibromide (EDB) at levels in excess of the maximum allowable for drinking water. In October, 1988, the Petitioner completed and filed a Grant Application for EDB Clean-Up Funds. As part of the application, the Petitioner agreed that DER could: arrange for the purchase and installation of appropriate filters and inhibitors; provide a new well; or arrange for the connection of [the Petitioner's] well to an existing public supply system, whichever is more cost-effective as determined by the Department of Environmental Regulation. DER contracted with Continental Water Systems to provide a temporary carbon filter system for La Casa's water supply system to remove the EDB and supply uncontaminated drinking water to the development, pending a permanent solution to the EDB contamination. The temporary filter system was designed to provide 100 gallons per minute of water, which should have been adequate for drinking water needs at La Casa. However, water pressure problems arose due to algal growth and the use of the system for irrigation purposes in addition to the drinking water purposes for which it was designed. DER is a member of the Ground Water Task Force, which met biweekly or monthly to discuss, among other things, potable wells contaminated with EDB. Other member agencies are the Department of Heath and Rehabilitative Services, the Department of Agriculture and Consumer Services, the Department of Transportation and the Department of Community Affairs. The Task Force discussed the La Casa contamination problem and agreed that the possibility of having La Casa connected to an existing water supply should be explored. DER began negotiating both with Polk County and with Haines City for a water line connection. Connection with the Polk County line would have been more expensive, and Polk County was not particularly interested in extending its line. Negotiations continued with Haines City. Negotiations with Haines City progressed to the point that DER was able to present for consideration by the Task Force cost figures for a permanent filter system at La Casa, with ten years of projected cost of operation and maintenance, as compared to the cost of extending the Haines City line. The Task Force agreed with DER that extending the Haines City line north to La Casa and connecting La Casa to it was the most cost-effective use of state funds to remedy the EDB problem at La Casa, particularly in view of other EDB-related drinking water supply problems in the area and anticipated future drinking water supply problems in the area. The Petitioner was not invited to participate in the negotiations with Polk County and Haines City and did not participate in them. Nor was the Petitioner invited to participate in either the DER or the Task Force decision- making process, and the Petitioner did not participate in those processes, either. However, the Petitioner, through his engineering consultant, was made aware in early 1989 that DER was exploring options to have La Casa connected to an existing water supply. DER paid approximately $400,000 for the Haines City water line extension and La Casa connection. This included $90,000 for Haines City impact fees to cover the 175 then existing mobile homes at La Casa (DER actually paid $450 per unit for 200 units), as well as the plumbing contractor fees for connecting La Casa to the extended city water line. It also includes the cost of installing a water meter at La Casa. The ten-year cost to the DER to solve just the La Casa drinking water problem using an EDB filter system would have been less than the cost to the DER of extending the Haines City line and connecting La Casa to it. But the evidence is clear that, in the long run, and taking into consideration other EDB-related drinking water supply problems in the area, and anticipated future drinking water supply problems in the area, the most cost-effective use of state funds to remedy the problem was to extend the Haines City line and connect La Casa to it. (Even the Petitioner's expert witness agreed that the Haines City extension and connection was the most cost-effective use of state funds to remedy the area's EDB problem.) DER advised the Petitioner of its agreement with Haines City in approximately May or June, 1989. By letter dated July 27, 1989, DER explained to the Petitioner the details of the agreement, specifically what DER would pay and what DER would not pay. By the fall of 1989, the Petitioner knew that work was beginning. At the time, the extension of the Haines City line and connection to La Casa was projected for completion in January, 1990, but there were delays, and the city water supply was not ready to be connected to La Casa until August, 1990. By this time, a dispute had arisen between the Petitioner and DER as to the cost to the Petitioner of connecting to the city water, and actual connection was further delayed. Finally, by letter dated October 11, 1990, DER gave the Petitioner an ultimatum: either be connected to the city water supply; or forfeit any state contribution to the cost of remedying the EDB contamination of the Petitioner's water supply. Faced with the prospect of having to open the winter peak season without any drinking water, the Petitioner agreed, under protest, to be connected to the city water supply, and initiated formal administrative proceedings to challenge DER's intended decision to limit the extent to which the DER would cover the Petitioner's costs. There was evidence that the plumbing contractor hired by DER may have caused damage to the landscaping and one mobile home that has not yet been repaired. However, DER acknowledged its responsibility for the damage and intends to have the plumbing contractor repair the damage. There also was evidence that the Petitioner received a bill from Haines City for the installation of a water meter at La Casa. But the evidence also was that DER may already have paid the bill. In any event, DER acknowledges its responsibility for the cost of the water meter as part of the cost of connecting La Casa to the extended city water line. Although DER had the Haines City water line extended in response to the Petitioner's Grant Application for EDB Clean-Up Funds, two commercial properties south of La Casa were connected because of EDB contamination, and the line also was extended north of La Casa in preparation to address anticipated future EDB contamination problems. Under the DER's response to the Petitioner's Grant Application, each additional mobile home unit over 200 connected to the city water supply will require the payment of a $450 impact fee. In addition, Haines City will charge monthly water fees of $1.80 1/ per 1000 gallons for the use of water at La Casa, with a $1,000 minimum charge per month. 2/ Based on current occupancy of 200 lots, the Petitioner estimates water fees of $42,000 per year, figured at approximately $5,000 per month for six peak months (based on a recent peak season monthly bill) and $2,000 per month for six off-peak months. However, it is not clear whether some of that estimated usage includes irrigation. If, in order to save gallonage fees, the Petitioner puts in a separate irrigation system supplied by its well, it will have to put in a separate distribution system since the current system is being used to bring city water to the lots. This would cost approximately $90,000. The Petitioner has paid approximately $2,100 in engineering fees to assess the problem with the temporary filter and to propose solutions, to estimate the cost of installing a separate irrigation system, and to estimate the cost to the Petitioner of connecting to the Haines City water supply. There was no evidence as to the reasonableness of those fees. The Petitioner also has paid approximately $4,500 in attorney fees to negotiate with the DER for payment of a larger portion of the Petitioner's cost of connecting to the Haines City water supply. There was no evidence as to the reasonableness of the attorney fees.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Department enter a final order dismissing the Amended Petition for Formal Hearing in this case. RECOMMENDED this 14th day of March, 1991, in Tallahassee, Florida. J.
