The Issue Whether the Petitioner's water supply system that supplies water to residents of Cypress Knee Cove comes under the jurisdiction of the Respondent and, if so, is the level of Ethylene dibromide (EDB) in the water supplied by Petitioner an imminent hazard to the residents of Cypress Knee Cove.
Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant facts are found. Petitioner George T. Donaldson owns and operates Cypress Knee Cove Mobile Home Park (Park) a residential mobile home park located at 3300 Canal Road, Lake Wales, Polk County, Florida. Petitioner owns and operates a water system providing piped water for consumption and use by the residents of the Park. The water system uses a groundwater source and can have up to 32 connections. The water system is presently connected to 27 mobile homes. Of those 27 mobile homes, one is vacant, 11 are used year-round, 15 are used seasonally. Of those being used seasonally, four are being used six months or more out of the year. Nineteen residents live in the 11 mobile homes used year-round and eight residents live in the four mobile homes 6 months or more out of the year. There are a total of 46 residents living in the Park during the year. The balance of the residents live in the Park less than 6 months out of the year. All of the mobile homes at the Park are permanently mounted and remain on the lots year-round. Twenty-five of the mobile homes in the Park are privately owned by residents of the Park and are available for year-round occupancy by the owner. Sampling for EDB from Petitioner's water system at the Park are done by the Department of Health and Rehabilitative Services, Polk County Health Unity (PCHU) on March 14, 1984 and the samples analyzed by the University of Florida (UF) for EDB. The UF reported EDB concentration of 0.02756 ppb. No samples of water from Petitioner's water system at the Park were collected by PCHU for testing for EDB from March 14, 1984 and until April 4, 1988. The PCHU began sampling Petitioner's water system at the Park again in April, 1988 and submitting those samples to the Department of Health and Rehabilitative Services (HRS) state certified laboratory in Jacksonville, Florida for analysis. The following are the results of those tests: Date of Sampling EDB Level April 4, 1988 below detectable level of 0.02 ppb - BDL August 17, 1988 0.17 ppb October 5, 1988 unconfirmed positive- resample November 7, 1988 0.058 ppb November 22, 1988 BDL-analytical problem- resample December 1, 1988 BDL January 4, 1989 0.062 ppb *January 18, 1989 0.070 ppb July 26, 1990 0.058 ppb *split sample with P.E. LaMoreaux and Associates P.E. LaMoreaux and Associates, a private state certified laboratory (PELA), analyzed samples taken from Petitioner's water system at the Park. The following are the results of those samples: Date of Sampling EDB Level August 23, 1988 BDL October 12, 1988 BDL *January 18, 1989 0.12 ppb **January 18, 1989 BDL *split sample with HRS **Revised report of January 18, 1989 split sample with HRS The Sun Air water system is owned and operated by Polk County and potable water for the Park is immediately available from this water system. The cost of connection to Polk County's Sun Air water system for residents in this area is covered under the state of Florida's EDB grant program. However, since the mobile homes do not have individual meters from Petitioner's water system, the grant will only pay for one hook-up. A water line from Sun Air runs along Canal Road beside the Park and is available for immediate connection. Although the hook-up is paid for by the grant, Polk County would charge for the water furnished to the Park. Sun Air water system was sampled in May, 1986 and again in July, 1990. The 1986 sample was analyzed by PELA and the level of EDB was BDL. The 1990 sample was analyzed by HRS and the EDB level was also BDL. An alternative method of treating EDB contamination at the Park would be the installation of a carbon filter system which cost approximately $3,000.00. Fluctuations in the EDB level may be due to the nature of EDB and the local hydrology. Should Petitioner hook-up to the Sun Air water system, his present well may be used for irrigation or watering lawns. There was no evidence adduced at the hearing concerning the allegation of cost in Count III.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED: That the Department of Environmental Regulation enter a final order directing Petitioner to connect to the available and approved Polk County water system or install a treatment system necessary for the reduction of EDB below the established MCL and placing appropriate and reasonable time schedule for commencing and completing either alternative and other conditions deemed appropriate and reasonable under the circumstances. It is further Recommended that Count II be dismissed. DONE and ENTERED this 26th day of October, 1990, in Tallahassee, Florida. WILLIAM R.

Findings Of Fact Ed Smith is the President of Riverside Village Mobile Home Park, Inc., which in turn is the owner of the mobile home park in question in this case. The mobile home park is located in Ruskin, Hillsborough County, Florida. Petitioner was served with an Administrative Complaint alleging that the chlorine residual in the park water supply distribution system was inadequate and that this constituted a violation of Chapter 513 and Section 386.041(1)(f), Florida Statutes, as well as Rule 10D-26.67(1), Florida Administrative Code. Specifically, the Administrative Complaint alleges violations occurring between July 16, 1986 and July 29, 1986, and seeks the imposition of a civil penalty in the amount of $500 per day which "shall be calculated when this complaint is received by the (Petitioner), and will run until the violation has been corrected." Petitioner requested a hearing to contest these allegations, and his request was filed with Respondent's Clerk on October 8, 1986. It was not established by competent substantial evidence when Petitioner "received" the Administrative Complaint which is the subject of this action. The only evidence of any violation occurring between July 16 and July 29, 1986 was the testimony of Harry Messick who signed an Official Notice and Notice of Intended Action which were both dated July 16, 1986, and which alleged that "chlorine reading found at time of inspection (was) between 0.1 ppm and (a) trace." However, Messick did not perform any test to either produce or confirm this result. He testified that someone else performed the field test, but there was no testimony from anyone else who may have actually conducted a test on Petitioner's water supply system on July 16, 1986. Therefore, it has not been established by competent substantial evidence that Petitioner's water supply system on July 16, 1986, was in violation of the requirement that .2 mg/1 of free chlorine residual be maintained. Testimony from Respondent's other witnesses, Norman Vik and Neil R. Schobert, indicates Vik was not even at Petitioner's mobile home park between July 16 and 29, 1986, and the only test conducted by Schobert found that Petitioner's water supply system was in compliance on July 24, 1986. Design modifications in Petitioner's water supply distribution system were approved by the Hillsborough County Health Department on July 9, 1986.
Recommendation Based on the foregoing, it is recommended that Respondent enter a Final Order DISMISSING the Administrative Complaint filed against Petitioner.

Findings Of Fact At all times pertinent to the issues herein, the Southwest Florida Water Management District had permitting authority for the issuance of consumptive use permits in the area in which Respondent, El Jobean, proposes to sink its irrigation well. On December 12, 1988, El Jobean submitted a consumptive use permit application to sink a new well for the purpose of irrigation of a golf course to be developed on the property it owns in Sarasota County. The well is to be located in the NE 1/4 of the NE 1/4 of Section 32, Township 365, Range 20R, in Sarasota County, Florida near the southern boundary of an irregularly shaped piece of property consisting of approximately 855 acres, owned by the applicant, which extends over Sections 28, 29, 32 and 33, Township 365, Range 20E. Respondent proposed to sink a 10 inch diameter well to a total depth of approximately 900 feet with casing in the well now to extend down to 300 feet, with a pump capacity of 1,000 GPM. The golf course to be irrigated is to encompass approximately 190 acres. The applicant requested authority to withdraw an average of 600,000 GPD with a limitation of a maximum of 1,440,000 GPD. The application was properly staffed by the District. In the staff report on the application, the average daily use limitation was expanded to 707,000 GPD; consumptive use was raised from 0 to 139,000 GPD; and maximum daily consumption was reduced from 1,440,000 GPD to 1,240,000 GPD. These changes were due to correction of arithmetic errors in the application and were accepted by the applicant. The ultimate recommendation of the staff was for approval of a 6 year permit, subject to certain conditions outlined in subparagraph I of the staff report. These special conditions require the provision and use of flow measuring devices to maintain an accurate record of the water withdrawn; the maintenance of flow records and the providing of periodic reports to the District; the collection and analyzing of water quality of samples taken from the well to measure the appropriate parameters for chlorides, sulfates, and total dissolved solids; the reporting of the results of these samplings and a description of the sampling and analytical methodologies employed; and a requirement that the permittee investigate the feasibility of supplementing and/or substituting drawn water with treated sewage affluent. After the staff report was submitted, proper notice of the District's intent to issue the permit was published. Based on that notice, protests were filed both by Miakka and Mr. Bishop. The area in question is located within the Manasota Basin which, itself, is located within the Southern West-Central Florida Ground Water Basin, (SWCFGWB), which encompasses all of Pasco, Hillsborough, Manatee, Sarasota, Polk, Hardee, and DeSoto Counties, and parts of Lee, Glades, Charlotte and Highlands Counties. The SWCFGWB sits atop several aquifers which include the Floridian Aquifer, two Intermediate aquifers, and the Surficial Aquifer. The Floridian Aquifer is the deepest and the Surficial Aquifer is on the top. The Miakka Community Club is a Florida corporation made up of residents of the pertinent area whose primary function is to preserve and conserve the rural nature and spirit of the Northeast section of Sarasota County. The club performs this function through educational programs, community activities, and participation in the legislative process. Miakka urges denial of the permit sought by El Jobean based on its membership's belief that the property owners whose property is in the immediate vicinity of the proposed well will be adversely affected if El Jobean is permitted to sink its well and withdraw water from it. The club membership believes that approval of El Jobean's well will result in contamination of existing personal water wells due to excessive use by El Jobean; potential contamination of Sarasota County's future drinking water sources which include the capital Ringling,/MacArthur tract and the Myakka River; reduction of property values; and destruction of personal resources. Petitioner also urges that since the proposed golf course will be a part of a private club for the use of members only, in which membership will be limited, there is no public benefit derived from the approval of and sinking of the well in question. Petitioner also contends that during the periods of severe water shortage as are being currently experienced, permission to sink a well of this size to draw water in of the magnitude expressed in the application, would be counterproductive and detrimental to the interests of the other property owners in the area. In support of its claim, Petitioner presented the testimony of two homeowners from the area, Mr. Richardson and Ms. Mustico. Mr. Richardson, whose well is 183 feet deep, has had several problems with his well even without the instant drilling. In 1974, and subsequent thereto, he has had to go deeper with a suction pipe because the water has dropped below the level of the tail pipe. Ms. Mustico's 160 foot deep well, with 80 feet of casing, is used to supply water for the home. She also has other wells for watering her lawn and for livestock, one of which goes down 500 feet. She is concerned that the well proposed by El Jobean will adversely impact her ability to draw water from her wells because, she believes, the water level from which her water is drawn will drop. In the past, her primary well has gone dry and the wells of several neighbors have gone dry as well. Through maps and other documentation taken from the Ground Water Resource Availability Inventory for Sarasota County, Florida, prepared by the District in March 1988, Petitioner has established that areas of significant groundwater withdrawal within the SWCFGWB occur in Hillsborough, Manatee, Polk, Hardee, DeSoto and Highlands Counties. With the exception of an extremely small portion of Sarasota County located contiguous to Manatee County, there appear to be no areas of major ground water withdrawal currently existing in Sarasota County. The majority of the major municipal well fields within the pertinent basin that are located within Sarasota County, extend down to the Intermediate and Surficial Aquifers with only 3 extending through the lower Intermediate into the Floridan Aquifer. These include the Verna well field located in the northeast corner of Sarasota County where it abuts Manatee County; the Sarasota County well field located in northwest Sarasota County near the Manatee County line; and the Sorrento Utility, Inc., well field which is located near the Gulf Coast, approximately two-fifths of the way down between the Manatee and Charlotte County lines. With the exception of the Verna well field, all the municipal well fields in Sarasota County appear to be reverse osmosis systems and as of 1987, there were 28 reverse osmosis systems located within Sarasota County. Most are relatively small in their output measured in millions of gallons per day. With the exception of 3 public supply wells, 2 of which are permitted an average annual pumpage greater than 100,000 GPD and 1 of which is permitted less, all of the permitted public supply well fields in Sarasota County are located west and south of 1-75 as it extends from the Manatee County line in the north to the Charlotte County line in the south. The El Jobean well would be located east of the line, in that area occupied by the 3 public supply wells. Generalized recharge areas for the upper Floridan Aquifer in the groundwater basin in issue here have been categorized from "high", with a rate of more than 10 inches per year, to "Generally none", with a recharge rate at 0. In 1980, the high recharge rates existed in the north-central part of Pasco, the eastern part of Polk County, and the northeastern part of Highlands County. Sarasota County is in an area wherein the recharge rate was either very low or generally none. In September 1986, the high recharge rate was found in a very small area of northeastern Pasco County, and small areas in both Polk and Highlands Counties. Sarasota County, for the most part, was classified as having no recharge. In May 1987, the high recharge rates were, again, a small area in eastern Pasco County, a small area in northeastern Hillsborough County, a small area in southeastern Polk and northwestern Highlands Counties, and a minuscule area in central Pinellas County. Again, Sarasota County had a recharge rate of 0. Generalized estimated, calibrated, model-derived recharge and discharge values for the upper Floridan Aquifer in the ground water basin in issue here, as they pertain to Sarasota County, reflect positive 2 recharge to negative 1 discharge inches per year. Historically, however, the northeast portion of Sarasota County, where the El Jobean well in question would be located, evaluated by various individuals or agencies periodically from 1980 through 1988, reflects a recharge of anywhere from 0 to 2 inches per year. None of this documentation was supplemented, however, by direct testimony by an individual knowledgeable in this area, and Petitioner's main thrust appears to be an unsubstantiated fear that the sinking of El Jobean's well will have a negative impact on its membership's wells. Admittedly, the residents in the area in question all rely on private wells for the majority of their water supply, other than through the catchment of rainwater, which is insignificant. It was also established that the area has been undergoing a severe water shortage and that conservation measures have been mandated. On the other hand, El Jobean presented the testimony of a hydrogeologist, Mr. Moresi, who has extensive experience with the modeling process used to determine water consumption and recharge in southwest Florida and Sarasota County. The aquifer system in Florida is made up of water bearing limestone layers below the surficial sand base. This aquifer system underlays the various zones throughout the state and reflects a surficial aquifer extending from ground level down approximately 70 feet to a confining bed which separates it from the lower strata. This top confining bed is approximately 20 feet thick, and below it is the Tamiami-Upper Hawthorn Aquifer, which is between 100 and 200 feet deep and which rests on another confining bed somewhat thicker than the upper one. Below the second confining bed is the Lower Hawthorn-Upper Tampa Aquifer which extends approximately from the 250 foot to the 450 foot level at the Manatee County line, and between the 320 foot and the 710 foot level at the Charlotte County line. Another confining bed lays between this aquifer and the Floridan Aquifer which starts at the 500 foot level and goes down well below the 900 foot level in the north and extends from the 730 foot level down in the south. The confining bed below the surficial aquifer is made up of a clay material which retards the movement of water from one aquifer to another. The surficial aquifer is porous and saturated with water from the water table down. Since the confining beds are far less porous than the aquifers they separate, water moves much more slowly through them. The lower aquifers are made up of limestone and are also porous and contain water. The Tamiami-Upper Hawthorn formation consists of limestone and clay, but is water bearing. The Lower Hawthorn-Upper Tampa formation is similar and both make up the intermediate aquifer below which is the lower confining bed followed by the Floridan aquifer. Respondent's well would be cased in steel down to an area approximately 100 feet into the Floridan Aquifer, through the Lower Hawthorn- Upper Tampa Aquifer and through the lower confining bed. Since the well would be cased to well below the lower confining bed, water existing in the upper aquifers, would be prevented from being drawn down by operation, of the Respondent's well either directly or by settling down to replace the water drawn out. Generally, the deeper a well is drilled, the worse the quality of the water, and it becomes less potable. The Floridan Aquifer produces far more copious quantities of water than do the intermediate aquifers. However, since it is cheaper to drill to the intermediate zones as the wells need not be so deep, and since the water there is better, most domestic wells go no deeper than these aquifers. They go down approximately 150 to 180 feet. The pressure in each level is separate from and different from that in the other aquifers. The upper intermediate system generally has a lower pressure than the lower intermediate system. As a result, water from the lower intermediate system tends to leak upward toward the upper intermediate aquifer, rather than the reverse. In addition, a recent survey tends to show that the Floridan aquifer also tends to leak upward into the lower intermediate level. It also shows that leakage through the confining beds amounts to .002 GPD per cubic foot of aquifer. Petitioner claims that since the lower water is of lesser quality, and since withdrawal of water from the upper layers would promote leakage upward, thereby adding lower grade water to the better grade upper water, there could be a diminishment in upper level water quality as a result of water being drawn from the upper levels. However, according to Mr. Moresi, the .002 figure is so small it would result in an infinitesimally small drawdown of water level from the upper intermediate level aquifer and the potential for compromise of the water quality therein is remote. Clearly, this is not the result of drawing water from the Floridan Aquifer as the well in question would do but more the result of the residential wells extending into the upper levels. The District ran a model for the proposed El Jobean well (a Jacob- Hantush model) which showed that drawdown at the wellhead would be just over 2 feet. This means that use of the Respondent's well would reduce the water level in the Floridan Aquifer at the well head by 2 feet. However, this drawdown is shown to decrease rapidly out to where, at distance, it is almost immeasurable. In fact, drawdown of the Floridan Aquifer at 24,000 feet from the well head (approximately 4.5 miles) would be .1 feet, slightly or 1 inch. The .1 foot drawdown relates to the lowest (Floridan) aquifer and the resultant drawdown in the upper intermediate aquifer, into which the majority of residential wells are sunk, would be relatively undetectable. Since the Petitioner's wells, at their deepest, go only into the upper intermediate level, and would be separated by 2 confining beds from the Floridan Aquifer, the impact on the domestic wells at 2 miles from the El Jobean wellhead would be immeasurable. Even at 1 mile, there would be minimal drawdown in the Floridan Aquifer and almost none in the upper intermediate aquifer. The potentiometric surface of the intermediate layer would not be adversely affected, nor would that of the surface water. Recognizing the potential for saltwater intrusion which occurs all along the coast, based on his studies, Mr. Moresi concluded that the well in question here would not induce significant saltwater intrusion. He concluded as well that the permit is consistent with the requirements of the District rule; that the amount permitted for the use of irrigation of the golf course is reasonable, assuming a golf course is a reasonable and appropriate use of water; that the withdrawal by the well in issue would not have an adverse impact on users outside the property on which the well was located; that it would not impact existing users; that there is no other water available for the purpose intended; that the water taken from the Floridan Aquifer under this permit may be potable but is of poor quality; and that the applicant met rule standards. Mr. Moresi also discussed the possible cumulative impact of the proposed well when operated along with the currently existing wells. If there are other drawdowns from the same cone into which El Jobean's well would be sunk, the withdrawals would be cumulative. However, as best he can determine, the only other significant drawdown from the cone pertinent here is that of the Verna well field. In his opinion, that well field's drawdown, which is from the northeast, would not be significant even when considered with the El Jobean well. Mr. Moresi was also satisfied that while the confining bed separating the surficial aquifer from the next lower level might be disturbed, the deeper one goes, the less likely there is to be mixing of aquifers. The only instance where water could move from one level to another as a result of the well is where there is no casing on the bore hole. In the instant case, plans call for, and permit conditions require, the well to be cased to below the lowest confining bed. Consequently, there should be no upward or downward flow of water as a result of the bore. Mr. Tyson, who worked on the evaluation of El Jobean's application for permit, was of the opinion that the amount of water requested by El Jobean in its application was appropriate for a golf course. This does not mean that a golf course is an appropriate use of the property. The special conditions imposed on the granting of the permit by the District are designed to reduce any impact possibly caused by the permitted activity. The Jacob-Hantush model used in analysis of the instant application is considered to be a conservative tool and showed minimal drawdown at all property boundaries. The use of other models in this case was considered neither necessary nor appropriate. Mr. Tyson considers the proposed permit a reasonable beneficial use as defined in the Florida Administrative Code and statutes because it proposes use of reasonable amounts of water and the models indicate no unfavorable impact. Based on the past practice of permitting golf courses with subdivisions, he feels the proposed use is reasonable. He concludes, therefore, that it is in the public interest to grant this permit. In his opinion, the permit will not interfere with legal existing uses and meets all statute and rule requirements. Considering the evidence as a whole, it is found that petitioner has presented insufficient evidence to support its claim that approval and operation of El Jobean's well as proposed would have an adverse impact on the property owners. It's concerns are no doubt sincere, but these concerns are not sufficiently confirmed by evidence of record. At the hearing, the parties stipulated that if the permit were granted, it would be modified by the addition of two conditions: The proposed well shall be constructed with a minimum of 600 feet of casing so as to prevent the unauthorized interchange of water between water bearing zones in order to prevent the deterioration of water quality in the shallower zones. If the well cannot be properly completed to prevent such an unauthorized interchange of water, the well shall be abandoned and plugged in accordance with Rule 17-21.10(2)(c), F.A.C.. Upon completion of the well, a copy of the well construction completion report shall be sent to the District. The permittee shall line the bottom of the pond that will be used as the irrigation source, with clay to a thickness equal to 1.5 feet.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is, therefore: RECOMMENDED that the Southwest Florida Water Management District enter a Final Order issuing Consumptive Use Permit Number 209458, as modified by the conditions stipulated to at the hearing held herein on June 7, 1989, and outlined in Finding of Fact Number 27 herein, to El Jobean Philharmonic Group, Inc.

The Issue The issue is whether the applicant for an Environmental Resource Permit ("ERP"), the City of Deltona ("City" or "Applicant"), has provided reasonable assurance that the system proposed complies with the water quantity, environmental, and water quality criteria of the St. Johns River Water Management District's ("District") ERP regulations set forth in Florida Administrative Code Chapter 40C-4, and the Applicant's Handbook: Management and Storage of Surface Waters (2005).
Findings Of Fact The District is a special taxing district created by Chapter 373, Florida Statutes, charged with the duty to prevent harm to the water resources of the District, and to administer and enforce Chapter 373, Florida Statutes, and the rules promulgated thereunder. The City of Deltona is a municipal government established under the provisions of Chapter 165, Florida Statutes. The Lake Theresa Basin is comprised primarily of a system of interconnected lakes extending from Lake Macy in the City of Lake Helen to the Butler Chain of Lakes (Lake Butler and Lake Doyle). The Lake Theresa Basin is land-locked and does not have a natural outfall to Lake Monroe and the St. Johns River. In 2003, after an extended period of above-normal rainfall in the Deltona area, the lakes within the land-locked Lake Theresa Basin staged to extremely high elevations that resulted in standing water in residential yards, and rendered some septic systems inoperable. Lake levels within the Lake Theresa Basin continued to rise and were in danger of rising above the finished floor elevations of some residences within the basin. On March 25, 2003, the District issued an Emergency Order (F.O.R. No. 2003-38) authorizing the construction and short-term operation of the Lake Doyle and Lake Bethel Emergency Overflow Interconnection. Since wetland and surface water impacts would occur, the Emergency Order required the City of Deltona to obtain an ERP for the system. The project area is 4.1 acres, and the system consists of a variable water structure on the west shore of Lake Doyle connected to a series of pipes, swales, water control structures, and wetland systems which outfall to a finger canal of Lake Bethel, with ultimate discharge to Lake Monroe and the St. Johns River. The first segment of the system extends downstream from the weir structure on the west shore of Lake Doyle via a pipe entrenched in the upland berm of the Sheryl Drive right-of-way. The pipe passes under Doyle Road and through xeric pine-oak uplands to the northeast shore of a large (approximately 15 acres) deepwater marsh. Water flows south through the deepwater marsh where it outfalls through four pipes at Ledford Drive. Two of the four pipes are overflow structures, controlled by canal gates. The pipes at Ledford Drive discharge into a ditch and into a large (greater than 20 acres) shallow bay swamp. The south end of the bay swamp is defined (and somewhat impounded) by a 19th Century railroad grade. Water flows through the bay swamp where it outfalls through five pipes at the railroad grade. Three of the five pipes are overflow structures, controlled by channel boards. The pipes at the railroad grade discharge to a 1500-foot long finger canal that was dug some time during the period 1940-1972 from the north central shore of Lake Bethel. The overflow interconnection system has three locations whereby the system can be shut down: 1) Lake Doyle--a control weir, controlled by three sluice gates; 2) Ledford Drive--two thirty-inch reinforced concrete pipes, controlled by canal gates; and 3) railroad grade--three thirty-inch reinforced concrete pipes, controlled by channel boards (collectively referred to as "Overflow Structures"). The Overflow Structures are designed to carry the discharge of water from Lake Doyle to Lake Bethel. With the Overflow Structures closed the system returns to pre-construction characteristics, meaning there will be no increase or decrease in the quantity or quality of water throughout the path of the system as a result of the project. An unequivocal condition of the permit is that the system would operate with all of the Overflow Structures closed. As an added assurance, the City proposes to place a brick and mortar plug in the Lake Doyle weir structure outfall pipe to prevent any discharge from the weir. The City has submitted to the District preliminary plans for a future phase in which the system would be modified for the purpose of alleviating high water levels within the Lake Theresa Basin when the water level in Lake Doyle rises above an elevation of 24.5 feet. The District shall require a separate permit application to be submitted for such future plans. Petitioner, Barbara Ash, has lived on Lake Theresa for 19 years. Ms. Ash lives upstream from the area of the weir that will be plugged in accordance with the ERP. She does not trust either the City of Deltona to comply with or the District to enforce the conditions of the ERP applied for by the City. Petitioner, Barbara Ash, also served as the qualified representative for Petitioners, Francell Frei, Bernard J. and Virginia Patterson, and Ted and Carol Sullivan. Ms. Ash represented that Ms. Frei has lived on Lake Theresa for 12 years, and both the Pattersons and the Sullivans live on Lake Louise, which is within the area of concern in this proceeding. Petitioner, Diana Bauer, has lived on Lake Theresa since February 2004. She fears that the lake will become too dry if the system is allowed to flow. She also believes the wildlife will be adversely affected if the water levels are too low since many species need a swampy or wet environment to thrive. She fears her property value will decrease as a result of the approval of the ERP. She also does not trust either the City to comply with or the District to enforce the conditions of the ERP. Petitioner, Howard Ehmer, lives two to three hundred yards down Lake Theresa from Ms. Bauer. He is concerned about the lake bed being too dry and attracting people on all terrain vehicles who enjoy driving around the lake bottom. He is concerned about his property value decreasing if the lake bed is dry. Further, when the lake level is too low, people cannot enjoy water skiing, boating, and fishing on Lake Theresa. Petitioner, Phillip Lott, a Florida native, has also owned and lived on property abutting Lake Theresa since 1995. Mr. Lott has a Ph.D. in plant ecology, and M.P.A. in coastal zone studies, an M.B.A. in international business, and a B.S. in environmental resource management and planning. Mr. Lott has been well acquainted with the water levels on Lake Theresa for many years. Based upon his personal observations of the lake systems in the Deltona area over the years, Mr. Lott has seen levels fluctuate greatly based upon periods of heavy and light rainfall. Mr. Lott is concerned that the District will permit the City to open the weir to let water flow through the system and cause flooding in some areas and low water levels in other areas. He fears that the District will allow the water to flow and upset the environmental balance, but he admits that this ERP application is for a closed system that will not allow the water to flow as he fears. Mr. Lott similarly does not trust the City to comply with and the District to enforce the conditions of the ERP. Petitioners, James E. and Alicia M. Peake, who were represented by Steven L. Spratt at hearing as their qualified representative, live on Lake Louise, which is interconnected with the Lake Theresa basin. The Peakes are concerned that if the level of Lake Louise drops below 21 feet, nine inches, they will not be able to use the boat launch ramps on the lake. Petitioner, Steven L. Spratt, also lives on Lake Louise, and is concerned about the water levels becoming so low that he cannot use the boat launch on the lake. He has lived on the lake since 2000, and remembers when the water level was extremely low. He fears that approval of the ERP in this case will result in low levels of water once again. Petitioner, Gloria Benoit, has live on Lake Theresa for two years. She also enjoys watching recreational activities on the lake, and feels that approval of the ERP will devalue her lakefront property. Ms. Benoit appeared at the first day of the hearing, but offered no testimony on her behalf. J. Christy Wilson, Esquire, appeared prior to the final hearing as counsel of record for Petitioners, Steven E. Larimer, Kathleen Larimer, and Helen Rose Farrow. Neither Ms. Wilson nor any of the three Petitioners she represented appeared at any time during the hearing, filed any pleadings seeking to excuse themselves from appearing at the final hearing, or offered any evidence, testimony, pre- or post- hearing submittals. Petitioner, Gary Jensen, did not appear at hearing, did not file any pleadings or papers seeking to be excused from appearing at the final hearing, and did not offer any evidence, testimony, pre- or post-hearing submittals. Both the City and the District recognize that areas downstream from the project site, such as Stone Island and Sanford, have experienced flooding in the past in time of high amounts of rainfall. The system proposed by the City for this ERP will operate with the overflow structures closed and a brick and mortar plug in the outfall pipe to prevent water flow from Lake Doyle to Lake Bethel. So long as the overflow structures are closed, the system will mimic pre-construction flow patterns, with no increase in volume flowing downstream. The District has considered the environment in its proposed approval of the ERP. The area abutting the project is little urbanized and provides good aquatic and emergent marsh habitat. With the exception of the western shore area of the deepwater marsh ("west marsh area"), the bay swamp and remaining deepwater marsh area have good ecological value. In the 1940's, the west marsh area was incorporated into the drainage system of a poultry farm that occupied the site. This area apparently suffered increased nutrient influxes and sedimentation that contributed to a proliferation of floating mats of aquatic plants and organic debris. These tussocks reduced the deepwater marsh's open water and diminished the historical marsh habitat. Water under the tussocks is typically anoxic owing to total shading by tussocks and reduced water circulation. Thick, soft, anaerobic muck has accumulated under the matted vegetation. Exotic shrubs (primrose willow Ludwigia peruvania) and other plants (cattails Typha spp.) dominate the tussocks. The construction of the project, from the 2003 Emergency Order, resulted in adverse impacts to 1.3 acres of wetlands having moderately high- to high ecological value and 0.2 acres of other surface waters. The 0.2 acre impact to other surface waters was to the lake bottom and the shoreline of Lake Doyle where the weir structure was installed. The 0.3 acres of wetland impacts occurred at the upper end of the deepwater marsh where the pipe was installed. The largest wetland impact (1.0 acre) was to the bay swamp. The bay swamp is a shallow body dominated by low hummocks and pools connected inefficiently by shallow braided channels and one acre is filled with a 1-2 foot layer of sediment following swamp channelization. Disturbance plants (e.g., primrose willow, Ludwigia peruvania, and elderberry Sambucus Canadensis) now colonize the sediment plume. Pursuant to the District's elimination and reduction criteria, the applicant must implement practicable design modifications, which would reduce or eliminate adverse impacts to wetlands and other surface waters. A proposed modification, which is not technically capable of being done, is not economically viable, or which adversely affects public safety through endangerment of lives or property is not considered "practicable." The City reduced and/or eliminated the impacts to the lake bottom and shoreline of Lake Doyle and deepwater marsh, to the extent practicable. The impacts were the minimum necessary to install the weir structure and pipe for the system; the weir structure and pipe were carefully installed on the edges of the wetland and surface water systems, resulting in a minimum amount of grading and disturbance. To compensate for the loss of 1.3 acres of wetlands and 0.2 acres of other surface waters, the City proposes to preserve a total of 27.5 acres of wetlands, bay swamp, marsh, and contiguous uplands. Included in this 27.5 acres are 6.4 acres of the west marsh, which are to be restored. The parties stipulated that the mitigation plan would adequately compensate for losses of ecological function (e.g. wildlife habitat and biodiversity, etc.) resulting from the project. Water quality is a concern for the District. Lake Monroe is included on the Florida Department of Environmental Protection's verified list of impaired water bodies for nitrogen, phosphorous, and dissolved oxygen. Water quality data for Lake Monroe indicate the lake has experienced high levels of nitrogen and phosphorous and low levels of dissolved oxygen. Prior to construction of the project, there was no natural outfall from the Lake Theresa Basin to Lake Monroe and therefore no contribution from this basin to nitrogen and phosphorous loadings to Lake Monroe. Lake Colby, Three Island Lakes (a/k/a Lake Sixma), and the Savannah are surface waters within the Lake Theresa Basin for which minimum levels have been adopted pursuant to Florida Administrative Code Chapter 40C-8. The system will operate with the overflow structures closed and a brick and mortar plug in the outfall pipe to prevent water flow from Lake Doyle to Lake Bethel, resulting in no outfall from the Theresa Basin to Lake Monroe. Minimum flows established for surface waters within the Lake Theresa Basin will not be adversely impacted. Under the first part of the secondary impact test, the City must provide reasonable assurance that the secondary impacts from construction, alteration, and intended or reasonable expected use of the project will not adversely affect the functions of adjacent wetlands or surface waters. The system is designed as a low intensity project. As proposed, little activity and maintenance are expected in the project site area. The reasonably expected use of the system will not cause adverse impacts to the functions of the wetlands and other surface waters. None of the wetland areas adjacent to uplands are used by listed species for nesting or denning. In its pre-construction state, the project area did not cause or contribute to state water quality violations. Under the second part of the secondary impact test, the City must provide reasonable assurance that the construction, alteration, and intended or reasonably expected uses of the system will not adversely affect the ecological value of the uplands to aquatic or wetland dependent species for enabling existing nesting or denning by these species. There are no listed threatened or endangered species within the project site area. Under the third part of the secondary impact test, and as part of the public interest test, the District must consider any other relevant activities that are closely linked and causally related to any proposed dredging or filling which will cause impacts to significant historical and archaeological resources. When making this determination, the District is required, by rule, to consult with the Division of Historical Resources. The Division of Historical Resources indicated that no historical or archaeological resources are likely present on the site. No impacts to significant historical and archaeological resources are expected. Under the fourth part of the secondary impact test, the City must demonstrate that certain additional activities and future phases of a project will not result in adverse impacts to the functions of wetlands or water quality violations. The City has submitted to the District preliminary plans for a future phase in which the system would be modified for the purpose of alleviating high water levels within the Lake Theresa Basin when the level in Lake Doyle rises above an elevation of 24.5 feet. Based upon the plans and calculations submitted, the proposed future phase, without additional measures, could result in minor increases in the loadings of nitrogen and phosphorous to Lake Monroe. Lake Monroe is included on the Florida Department of Environmental Protection's verified list of impaired water bodies due to water quality data indicating the lake has experienced high levels of nitrogen and phosphorous, and low levels of dissolved oxygen. Under this potential future phase, there would be an outfall from the Lake Theresa Basin to Lake Monroe. To address the impact on water quality of this potential future phase, the City has submitted a loading reduction plan for nitrogen, phosphorous, and dissolved oxygen. The plan includes compensating treatment to fully offset the potential increased nutrient loadings to Lake Monroe. Specifically, the loading reduction plan includes: Construction and operation of compensating treatment systems to fully offset anticipated increased nutrient loadings to Lake Monroe. Weekly water quality monitoring of the discharge from Lake Doyle for total phosphorous and total nitrogen. A requirement that the overflow structure be closed if the total phosphorous level reaches 0.18 mg/l or higher or the total nitrogen level reaches 1.2 mg/l or higher in any given week and will remain closed until levels fall below those limits. The implementation of these water quality mitigation measures will result in a net improvement of the water quality in Lake Monroe for nitrogen, phosphorous, or dissolved oxygen. The future phase was conceptually evaluated by the District for impacts to wetland functions. The future phase as proposed could result in adverse impacts to wetland functions. Operation of the system with the overflow structures open could impact the bay swamp and deepwater marsh. The City has demonstrated that any adverse impacts could be offset through mitigation. Based upon the information provided by the City and general engineering principles, the system is capable of functioning as proposed. The City of Deltona will be responsible for the operation, maintenance, and repair of the surface waster management system. A local government is an acceptable operation and maintenance entity under District rules. The public interest test has seven criteria. The public interest test requires the District to evaluate only those parts of the project actually located in, on, or over surface waters or wetlands, to determine whether a factor is positive, neutral, or negative, and then to balance these factors against each other. The seven factors are as follows: the public health, safety, or welfare of others; conservation of fish and wildlife and their habitats; fishing, recreational value, and marine productivity; temporary or permanent nature; 5) navigation, water flow, erosion, and shoaling; 6) the current condition and relative value of functions; and 7) historical and archaeological resources. There are no identified environmental hazards or improvements to public health and safety. The District does not consider impacts to property values. To offset any adverse impacts to fish and wildlife and their habitats, the City has proposed mitigation. The areas of the project in, on, or over wetlands do not provide recreational opportunities. Construction and operation of the project located in, on, or over wetlands will be permanent in nature. Construction and operation of the project located in, on, or over wetlands will not cause shoaling, and does not provide navigational opportunities. The mitigation will offset the relative value of functions performed by areas affected by the proposed project. No historical or archaeological resources are likely on the site of the project. The mitigation of the project is located within the same drainage basin as the project and offsets the adverse impacts. The project is not expected to cause unacceptable cumulative impacts.

Findings Of Fact Background In 1983, Concerned Citizens of Citrus County, Inc. (Concerned Citizens), an intervenor in this case, filed a petition toe initiate rulemaking for single source reclassification of groundwater under the existing provisions of Rule 17-3.403, Florida Administrative Code (F.A.C.). In this manner, Concerned Citizens sought to have existent potable waters in Pinellas, Hillsborough, Pasco, Hernando, and Citrus Counties classified Class G-I groundwater, and to thereby provide them the most stringent water quality protection accorded groundwaters of the state. At a public meeting in February 1985, the Environmental Regulation Commission (ERC) deferred action on the petition of Concerned Citizens, and directed the Department of Environmental Regulation (Department) to review the existing G-I rule, prepare proposed revisions, and present its recommendations to the ERC. Following the ERC directive, the Department held numerous public meetings and workshops to explore different approaches to groundwater protection. As a consequence, it prepared the proposed revisions to Rules 17-3.021, 17-3.403, 17-3.404, and 17- 4.245, F.A.C., at issue in these proceedings. On October 31, 1986, the Department duly noticed the proposed rules in volume 12, number 44, of the Florida Administrative Weekly. The notice interested parties that a public hearing would be held on December 16, 1986, before the ERC. 1/ On December 16-17, 1986, the ERC held a public hearing at which time it considered the rules recommended by the Department. During the course of this meeting, the ERC approved and adopted the rules with certain changes. These changes were duly noticed in volume 13, number 3, of the Florida Administrative Weekly on January 16, 1987. Petitioners and Intervenors Petitioners, Adam Smith Enterprises, Inc., and Alliance for Rational Groundwater Rules (Case No. 86-4492RP), and Petitioners Aloha Utilities, Inc.; Interphase, Inc.; Phase 1 Homes, Inc.; A.C. & R., Inc.; Tahitian Development, Inc.; Great Cypress Mobile Village, Inc.; and Barrington, Ltd. (Case No. 86- 4705R), filed timely petitions to challenge the validity of the proposed rules, which petitions were consolidated for hearing. Petitions for leave to intervene were granted on behalf of Florida Electric Power Coordinating Group, Inc.; Florida Land Council, Inc.; and Pasco County. These Intervenors' interests were aligned with those of petitioners. Petitions for leave to intervene were a1so granted on behalf of West Coast Regional Water Supply Authority and Concerned Citizens of Citrus County, Inc. These Intervenors' interests were aligned with those of the Department and the ERC. Petitioner, Adam Smith Enterprises, Inc. (Adam Smith), is the owner/developer of a 3,800-acre development of regional impact (DRI) to be known as Trinity Communities. This development, which has been in the acquisition and planning stages for almost 5 years, is currently undergoing DRI review and Adam Smith anticipates that it will receive its development order by September 1987. The Trinity Communities development is located predominately in Pasco County, with just over 250 acres of its lands located in Pinellas County. These properties are predominately open pasture land, and are bordered on the north, east and west by roads and on the south by Hillsborough and Pinellas Counties. As proposed, the Trinity Communities development will include 1100 acres of parks, golf courses, and other open areas. The remaining lands will be developed to accommodate 9500 dwelling units, as well as industrial and commercial uses to service the community, over a 20-year period. At today's market value, the property represents an investment of approximately 28 million dollars. Abutting the Trinity Communities development is the Eldridge-Wilde Well Field. This well field is covered by consumptive use permits issued by the Southwest Florida Water Management District (SWFWMD), and contains major public community drinking water supply wells as defined by the rules at issue in this proceeding. Of these wells, 5 are located within 9.63 feet and 181.5 feet of the proposed development's property line, and 5 are located with 204.72 fee and 297.5 feet of its property line. Petitioner, Alliance for Rational Groundwater Rules (Alliance), is an association of landowners who united to educate themselves about the proposed rules. The proof failed, however, to establish whether Alliance had ever elected any officers or directors, or the magnitude of its membership. Consequently, the proof failed to establish that a substantial number of its members, although not necessarily a majority, were substantially affected by the proposed rules, and that the relief requested by it was of a type appropriate for it to receive on behalf of its members. Petitioner, Aloha Utilities, Inc. (Aloha Utilities), is a utility certified by the Florida Public Service Commission to provide water and sewer service to two separate service areas in southern Pasco County. Currently, Aloha Utilities operates an 850,000 gallon per day (gpd) sewage treatment facility (Aloha Gardens) and a 1.2 million gpd sewage treatment plant (Seven Springs). It also operates 10-11 producing wells, at least 7 of which are permitted by SWFWMD to withdraw at least 100,000 gpd. One of these wells is located approximately 1/4-1/2 mile from an Aloha Utility sewage treatment plant. At least 3 of Aloha Utilities' wells which are permitted to withdraw 100,000 gpd or more, will service or are servicing the Riverside projects and Aloha Gardens Unit Number 12 project discussed infra. Consequently, the proof establishes that Aloha Utilities operates a major public community drinking water supply system as defined by the subject rules. The Aloha Gardens facility is under a Department order to expand its effluent disposal capacity. To satisfy the Department's order and the need for increased disposal capacity, Aloha Utilities commenced condemnation proceedings 8-12 months ago to secure the needed property. While the condemnation proceeding is not yet completed, Aloha Utilities has already expended considerable sums for engineering studies and attorney's fees in its efforts to acquire the property. That property is located approximately 1/2 mile from an existing well that is permitted for an average daily flow of at least 100,000 gpd. The effluent disposal capacity of the Seven Springs facility is also being expanded to meet existing and future demand. In April 1987, Aloha Utilities acquired a 27-28 acre parcel of land immediately adjacent to its existing facility. Upon these lands, Aloha Utilities proposes to construct percolation ponds, a rapid rate land application effluent disposal process. As sited, these ponds would be located 1/2 to 3/4 of a mile from a well permitted for an average daily flow of 100,000 gallons or more. 2/ Petitioners, Interphase, Inc., Phase 1 Homes, Inc., and Tahitian Development, Inc., are corporations with common management which are developing three separate but geographically proximate projects in Pasco County. These projects will be, or are, serviced by Aloha Utilities. Interphase, Inc., is the owner/developer of a 100- acre tract known as Riverside Village Unit Number Four. This property is currently being developed to include 57 acres dedicated to single family use and 43 acres dedicated to multifamily use, and will require the installation of stormwater facilities and underground sewage transportation facilities. Two wells of Aloha Utilities that are permitted for an average daily flow of 100,000 gallons or more are located 1/2 mile and 1/3 mile, respectively, from this development. Interphase, Inc., is also the owner of a 17-acre parcel of vacant land in Pasco County that is zoned commercial. This property is located within 400 feet of Aloha Utilities' Seven Springs sewer treatment plant, and its development will require the installation of underground sewage transportation facilities. Phase 1 Homes, Inc., is the owner/developer of a project known as Riverside Village Townhouses. This project is fully developed and is currently serviced by Aloha Utilities. Located within 1/2 mile of the development are two wells of Aloha Utilities that are permitted for an average daily flow of 100,000 gallons or more. Tahitian Development, Inc., is the owner/developer of a 40-acre tract known as Riverside Villas. Twenty of these acres have been developed and some of the units sold. The remaining 20 acres are currently under development. In developing its remaining 20 acres, Tahitian Development would be required to install stormwater drainage systems and sewage transportation lines to connect with Aloha Utilities. Located within 1/2 mile of the development are wells of Aloha Utilities that are permitted for an average daily flow of 100,000 gallons or more. Tahitian Development also owns a 40-acre parcel in Orange County which it plans to develop for light industrial uses such as an industrial park or an office complex. Such development would result in at least a 40 percent impervious surface, including building tops, within that 40-acre parcel, and require the installation of a sewage transportation system and a stormwater drainage system. Petitioner, A.C. & R., Inc., is the owner/developer of a project in Pasco County known as Aloha Gardens Unit Number 12. The project, which currently is represented by 40-50 developed lots, is located just north of the Aloha Gardens sewage treatment facility, and is serviced by Aloha Utilities. Located within 1/2 mile of the development that is permitted for an average daily flow of 100,000 gallons or more. Petitioner, Great Cypress Mobile Village, Inc., is the owner/developer of a 149 unit mobile home park in Pasco County. Twenty of these units are completed and ready for occupancy. Completion of the project will require the installation of additional sewer lines. Located at the interior of the property is a sewage treatment plant owned by Northern Utilities which services the project, and within 600 feet of the project's boundary there is a well which services that utility. The capacity of that well was not, however, demonstrated in these proceedings, nor was it shown whether such well was part of a community water system. Petitioner, Barrington, Ltd. is a party of unknown capacity, origin, or interest. No evidence was presented on its behalf to demonstrate that its substantial interests would be affected by the proposed rules. Intervenor, Florida Electric Power Coordinating Group, Inc. (FCG), a Florida corporation, is an association of Florida's electric utilities, and is composed of 37 members. The FCG has, as part of its internal organization, an environmental committee whose purpose is to participate in regulatory development and provide mutual member assistance with regard to water related matters. This committee was authorized by the FCG executive committee to participate in the development of the rules at issue in these proceedings, as well as Intervene in these proceedings, to represent and protect the interests of FCG members. The FCG participated in the development of the subject rules by the Department, and was granted full party status by the ERC during that rulemaking process. The members of FCG are owners and operators of electric power generating facilities. These facilities“ include the power plant and ancillary facilities such as substations. Incident to the operation of these facilities are wastewater discharges associated with the production of electricity and stormwater discharges. One of these facilities, Gainesville Regional Utilities' Deer Haven generating station is located across Highway 441 from a major community drinking water supply well. Intervenor, Florida Land Council, Inc., a Florid corporation, is composed of 12 primary members who own large tracts of land in interior Florida, and who are engaged primarily in agribusiness. The Land Council's purpose is to protect the asset value of its members property and, because of that purpose, it is concerned with environmental regulations, growth management regulations, land use regulations, and comprehensive planning. To protect its interests, the Land Council sought leave to intervene in these proceedings. There was, however, no proof that any lands owned by any member of the Land Council were proximate to any major public community drinking water well. Intervenor, Pasco County, is the owner/operator of 25 wastewater treatment plants with capacities In excess of 100,000 gallons per day, and has under construction, or in the design stage, additional facilities with capacities in excess of 100,000 gallons per day. The construction of these new facilities will require the installation of new lines for the collection of wastewater. Pasco County's current, as well as its planned, wastewater treatment facilities will utilities a rapid rate land application effluent disposal process. Within a mile of any wastewater treatment plan operated by Pasco County can be found a major public community drinking water well as defined by the rules at issue in these proceedings. Pasco County also owns and operates wells within the county with permitted withdrawal rates exceeding 100,000 gpd, and participates in the ownership and management of their wells with permitted withdrawal rates exceeding 100,000 gpd through West Coast Regional Water Supply Authority. Pasco County currently has plans to add new production wells in the county with an average daily pumpage in excess of 100,000 gallons per day. Intervenor, West Coast Regional Water Supply Authority (West Coast), is an interlocal government body created in 1974 to develop, store, and supply water to its member governments so that all citizens within the areas served by the authority may be assured an adequate supply of water. Member governments served by WCRWSA are Hillsborough County, Pasco County, and the cities of St. Petersburg and Tampa. Wellfields operated by West Coast are the Starkey Wellfield located in west central Pasco County, which serves the citizens of New Port Richey and Pasco County; the South-Central Hillsborough Regional Wellfield located in south-central Hillsborough County, which serves the citizens of Hillsborough, County; the crossbar Ranch Wellfield located in north-central Pasco County, which principally serves the citizens of Pinellas, County; the Cypress Creek Wellfild located in south-central Pasco County, which serves the citizens of Hillsborough, Pinellas, and western Pasco Counties and the City of St. Petersburg; the Northwest Hillsborough Wellfield located in northwest Hillsborough County, which serves the citizens of Hillsborough County; the Section 21 Wellfield located in northwest Hillsborough County, which serves the citizens of the City of St. Petersburg; and, the Come-Odessa Wellfield located in northwest Hillsborough County, which serves the citizens of the City of St. Petersburg. 3/ Each of the wellfields operated by West Coast are public community water systems, and contain wells permitted to withdraw in excess of 100,000 gallons per day. Collectively, these wellfields serve a total population of 800,000 persons. Intervenor, Concerned Citizens of Citrus County, Inc. (Concerned Citizens), is a not-for-profit corporation, was chartered in 1981, and has 350 members who obtain their drinking water from operational community water supply wells permitted for over 100,000 gallons per day in Inverness, Crystal River, Floral City, Sugar Mill Woods, Beverly Hills, and Rolling Oaks, Citrus County, Florida. The purpose of Concerned Citizens is to protect the natural resources of Citrus County through planning and zoning regulations, and local and state legislation and regulations. It was granted party status by the ERC. General aspects of the proposed rules The proposed rules establish new eligibility criteria for designation of an aquifer segment as Class G-I groundwater. Under the existing rule, the ERC could reclassify an aquifer or portion of an aquifer as G-I within specified boundaries upon a finding that: The aquifer or portion of the aquifer is the only reasonably available source of potable water to a significant segment of the population; and The designated use is attainable, upon consideration of environmental, techological, water quality, institutional, and social and economic factors. Under the proposed revisions, an aquifer segment could be classified by the ERC as G-I provided it was: ...within the zones of protection of a major public community drinking water supply well(s) or wellfield(s) withdrawing water from unconfined aquifers or from leaky confined aquifer... and, upon consideration of: ...environmental, technologial, water quality, institutional (including local land use comprehensive plans), public health, public interest, social and economic factors. As with thee existing rule, the proposed rules require that rulemaking procedures be followed to actually designate a G-I aquifer or aquifer segment at any particular location. The scheme envisioned by the proposed rules is to provide protection to "major community drinking water supply wells", community water systems that are permitted by consumptive use permit to withdraw an average daily amount of 100,000 gallons or greater of groundwater, by preventing contaminants from entering the groundwater within a circumscribed radius of the wells. To accomplish this purpose, the proposed rules establish a methodology whereby two zones of protection would be established around such wells if they were withdrawing waters from unconfined aquifers (an aquifer exposed to the atmosphere) or leaky confined aquifers (an aquifer in which groundwater moves vertically from the water table to the top of the aquifer in five years or less). The first zone (the inner zone) would be based on a fixed radius of 200 feet. The second zone (the outer zone) would be based on a radius, calculated under the rule's methodology, of 5 years groundwater travel time. Within the inner zone, discharges would be prohibited. Within the outer zone, certain developments which discharge to groundwater would be prohibited or restricted. A major emphasis of the proposed rules is to restrict discharges to groundwater within the zones of protection. For example, the rules eliminate the zone of discharge within the zones of protection, and require that new discharges to groundwater of treated domestic effluent meet the groundwater criteria specified in rule 17-3.404, F.A.C., prior to discharge. 4/ Additionally, such wastewater treatment facilities would be required to pre-treat industrial wastewater, provide daily monitoring to insure proper treatment plant process control, and provide 24 hour a day attendance of a wastewater operator under the general supervision of a Class A certified wastewater operator. New underground lines for the transport of domestic raw wastewater would be required to be constructed so that no more than 50 gallons per inch of pipe diameter per mile per day could leak into the ground. Within the 5 year zone of protection, there are no restrictions on stormwater discharges for residential developments. However, discharges from new stormwater facilities serving an area forty acres or larger with a forty percent impervious surface, excluding building tops, are required to monitor the discharge. Construction and operation of new sanitary landfills would be prohibited. As previously noted, to be eligible for reclassification as a G-I aquifer, the aquifer or aquifer segment under consideration must be leaky confined or unconfined. Whether the aquifer is leaky confined or not will be determined through application of the "Vv" and "Tv" formulae contained in the proposed rules, and the zones of protection will be established by reference to the "r" formula contained in the proposed rule. To date, neither the Department nor any party has applied the "Vv" and "Tv" formulae to identify wells hat are withdrawing from unconfined or leaky confined aquifers, nor has anyone delineated any zones of protection by application of the "r" formula. The Department has, however, identified those areas of the state at which it is likely that major community drinking water supply wells are withdrawing from such aquifers. Based on this identification, the Department has contracted with the U.S. Geological Survey (USGS) to "map" the Middle-Gulf region (Pinellas, Hillsborough, Pasco, Hernando, and Citrus Counties) by applying the "Vv" and "Tv" formulas to each well permitted to withdraw 100,000 gpd or more to determine if it is withdrawing from such aquifers and, if so, to delineate proposed zones of protection around such wells or wellfields through application of the "r" formula. The USGS is currently mapping the Middle-Gulf region. Pertinent to this case, the Department has identified all of Pasco and Pinellas Counties, the northern half of Hillsborough County, and most of Orange County including Orlando, as areas within which wells are most probably withdrawing from unconfined or leaky confined aquifers, and for which aquifers the Department will seek G-I reclassification. Under the circumstances, the parties have established, except as heretofore noted, that there is a reasonable likelihood that the proposed rules will substantially affect their interests. The rule challenge The gravamen of the protestant's challenge is that certain definitions and formulae continued within the proposed rule are vague, ambiguous, or not supported by fact or logic. The Protestants' also challenge the adequacy of the economic impact statement. The Protestants concerns are addressed below. Definitions Rule 17-3.021, as amended, would define "Confined Aquifer", "Leaky Confined Aquifer", and "Unconfined Aquifer", as follows: (7) "Confined Aquifer" shall mean an aquifer bounded above and below by impermeable beds or by beds of distinctly lower permeability than that of the aquifer itself. For the purpose of G-I, it shall mean an aquifer confined from above by a formation(s) which restricts the movement of groundwater vertically from the water table to the top of the confined aquifer for a period of more than five years * * * (16) "Leaky Confined Aquifer" shall mean, for the purposes of G-I, an aquifer confined from above by a formation(s) which allows groundwater to move vertically from the water table to the top of the leaky confined aquifer in five years or less. * * * (34) "Unconfined Aquifer" shall mean an aquifer other than a confined aquifer. For the purpose of G-I it shall mean an aquifer other than a confined or leaky confined aquifer. 5/ Protestants contend that the definition of "confined aquifer" and "leaky confined aquifer" are vague and meaningless because they are "defined by use of the phrase being defined". Accordingly, they conclude that proposed rule 17-3.021(7) and (16) must fall because they are without thought and reason, irrational and vague. Protestants further contend that since the definitions of "confined aquifer" and "leaky confined aquifer" are flawed, proposed rule 17-3.021(34), which defines unconfined aquifer, must also fall. The Protestants' contentions are not persuasive. If one were restricted to the definition of "confined", "leaky confined" and "unconfined" aquifer to glean their meaning, the rules might be considered vague. However, these definitions are, as they specifically provide, "for the purpose of G-I" and they must be read in context with the balance of the rule. When so read, it is apparent that "top of the confined aquifer" or "top of the leaky confined aquifer" is the top of the aquifer that has been calculated as confined or leaky through manipulation of the "Vv" and "Tv" formulae. Under the circumstances, the subject definitions are not vague, arbitrary or capricious. Proposed rule 17-3.021(20) provides: "New Discharge" shall mean, for the purpose of G-I, a discharge from a new installation; or a discharge from an existing permitted installation that has been altered, after the effective date of G-I reclassification, either chemically, biologically, or physically or that has a 211 22 different point of discharge, and which causes a significantly different impact on groundwater. Protestants contend that the definition of "new discharge" is vague, arbitrary and capricious because existing installations would be classified as new dischargers, and subject to the more stringent requirements of the proposed rules, whether the alteration of their discharge significantly improved or adversely affected groundwater. As proposed, the rule would so define new discharge, and it is not vague or ambiguous. The proof demonstrated, however, that the Department only proposed to define, as new dischargers, those existing installations whose altered discharge caused a significantly different negative impact on groundwater. The Department conceded this point, and offered no proof to demonstrate the reasonableness of classifying existing installations that improve their discharge as new discharges. Under the circumstances, proposed rule 17-3.021(20) is arbitrary and capricious. Proposed rule 17-3.021(35) defines "underground storage facility or underground transportation facility as follows: "Underground storage facility" or "underground transportation facility" shall mean that 10 percent or more of the facility is buried below the ground surface. This proposed rule is, however, only pertinent to proposed rule 17-4.245, which addresses the permitting and monitoring requirements for installations discharging to groundwater. Pertinent to this case, proposed rules 17-4.245(3)(c) and (d) establish construction requirements for the following facilities within the five year zone of protection: Underground storage facilities. An underground storage facility includes any enclosed structure, container, tank or other enclosed stationary devices used for storage or containment of pollutants as defined in Section 376.301(12), F.S. or any contaminant as defined in Sect ion 403.031(1), F.S. Nothing in this paragraph is intended to include septic tanks, enclosed transformers or other similarly enclosed underground facilities.... Underground facilities for transportation of wastewater or pollutants as defined in Section 376.301(12), F.S. or any contaminant as defined in Section 403.031(1), F.S. excluding natural and liquified petroleum gas. Underground facilities for transportation of waste effluent or pollutants or contaminants include piping, sewer lines, and ducts or other conveyances to transport pollutants as defined in Section 376.301(12), F.S., and contaminants as defined in Section 403.031(1), F.S.... Protestants contend that the proposed rules are contained in two separate chapters of the Florida Administrative Code with no bridge between them. Under such circumstances, they contend the rules fail to adequately define either facility in either chapter, and that the rules are therefore vague, arbitrary and capricious. Protestants' contention is not persuasive. Proposed rule 17-3.021(35) defines "underground storage facility" or "underground transportation facility" as meaning that 10 percent or more of the facility is buried below the ground surface. Proposed rules 17-4.245(3)(c) and (d) address what type of facility is included within the terms "underground storage facility" and "underground transportation facility." Notably, Rule 17-4.021, F.A.C., provides: Definitions contained in other chapters of the Department's rules may be utilized to clarify the meaning of terms used herein unless such terms are defined in Section 17-4.020, F.A.C., or transfer of such definition would defeat the purpose or alter the intended effect of the provisions of this chapter. Under the circumstances of this case, the rules are appropriately read together. So read, the construction requirements for "underground storage facilities" and "underground transportation facilities", as required by proposed rule 17-4.245(3)(c) and (d), are applicable if 10 percent or more of the containment device used for the storage or transport of pollutants is buried below the ground surface, and the proposed rules are not vague, arbitrary or capricious. Proposed rule 17-3.021(39) defines "Zones of Protection" as follows: "Zones of Protection" shall mean two concentric areas around a major public community drinking water supply well(s) or wellfield(s) drawing from a G-I aquifer whose boundaries are determined based on radii from the well or wellfields of 200 feet and five years groundwater travel time respectively. Protestants contend that the definition of "Zones of Protection" is vague, arbitrary and capricious because nowhere within the proposed rules is "G-I aquifer" defined. protestants' contention is not persuasive. Proposed rules 17-3.403(1) and (7) adequately explain what is meant by "G-I aquifer", and proposed rule 17-3.403(8) sets forth the metodology for calculating the zones of protection. The definition of "Zones of Protection", set forth in proposed rule 17-3.02(39) is not vague, arbitrary or capricious, because of any failure to define "G-I aquifer." Mapping Priorities When considering whether to reclassify an aquifer or aquifer segment as G-I, proposed rule 17-3.403(5)(e)2 requires that the aquifer or aquifer segment: Be specifically mapped and delineated by the Department on a detailed map of a scale which would clearly depict the applicable zones of protection. Maps will be grouped and submitted for reclassification generally on a regional basis. Mapping priorities shall follow the Commission directive of February 27, 1985. The remaining areas of the state will be mapped by the Department as time and resources allow. The mapping priority directive referred to in purposed Rule 17-3.403(5)(e)2a, was an oral directive of the ERC that Pinellas, Hillsborough, Pasco, Hernando, and Citrus Counties, referred to as the Middle-Gulf region, be mapped first. That directive has not been reduced to writing and, consequently, a copy thereof has never been available for inspection. Categories of G-I Aquifers and determination of zones and protection Proposed rules 17-3.403(7) and (8), respectively, set forth the eligibility criteria for reclassification as G-I aquifers and the methodology whereby the boundaries of the zones of protection are established. To this end, proposed rule 17- 3.403 (7) provides: Categories of G-I aquifers. For aquifers or aquifer segments to be eligible for potential reclassification as G-I aquifers one of the following criteria must be met: That the aquifer or aquifer segment under consideration be within the zones of protection of a major public community drinking water supply well(s) or wellfield(s) withdrawing water from unconfined aquifers or from leaky confined aquifers.... (b)(. reserved.) Proposed rule 17-3.403(8) provides: Determination of the boundaries of the zones of protection. (a) The boundaries of the zones of protection shall be based on radii from the wellhead or wellfield (if closely clustered, so that the five year zones of protection are overlapping) measured in 200 feet for the inner zone and five years for the outer zone. The radius of the outer zone shall be determined using the following formula: percent.x4n where Q = permitted average daily flow from the well (measured in cubic feet per day); T = five years (1825 days); 3.14 = mathematical constant pi; r = radius (feet); h distance from the top of the producing aquifer to the bottom of the hole (feet); n effective porosity. Protestants contend that the foregoing provisions of the proposed rules are vague, arbitrary and capricious because the wells that would be subject to and around which a zone of protection would be established cannot be identified or, if identifiable, do not comport with the Department's intent or interpretation. Protestant's concerns are not without merit. To be eligible for consideration as a G-I aquifer, proposed rule 17-3.403(7) requires that the aquifer segment be within the zones of protection of a "major public community drinking water supply well(s) or wellfield(s). Proposed rule 17- 3.021(17) provides that "major public community drinking water supply" shall mean: those community water systems as defined in Section 17-22.103(5), F.A.C., that are permitted by consumptive use permit to withdraw an average daily amount of 100,000 gallons or greater of groundwater. Community water system" is defined by Section 17-22.103(5) as: a public water system which serves at least IS service connections used by year- round residents or regularly serves at least 25 year-round residents. Facially then, the proposed G-I rules are applicable to "community water system" that hold a consumptive use permit to withdraw an average daily amount of 100,000 gallons or greater of groundwater", and which are withdrawing from unconfined or leaky confined aquifers. Notably, the rule does not ascribe the 100,000 gpd permitted rate of withdrawal to each well, but to a permit held by a community water system. Accordingly, under the literal reading of the proposed rules, each well covered by the consumptive use permit would be subject to a zone of protection regardless of its individually permitted rate, so long as it was withdrawing from an unconfined or leaky confined aquifer. While there may be legitimate reasons to designate zones of protection around wells, regardless of their individual permitted rate when the community water system holds a consumptive use permit to withdraw groundwater at a 100,000 gpd average, the Department advanced none. To the contrary, the Department contended that zones of protection were only to be established around a well that was permitted to withdraw an average daily amount of 100,000 gallons or greater. Under the circumstances, the provisions of proposed rules 17-3.403(7) and (8) are arbitrary and capricious. 6/ The "Vv" and "Tv" formulae Proposed rule 17-3.403(7)(a) prescribes the methodology where by vertical travel time will be calculated, and therefore whether a particular aquifer will be classified as confined or leaky confined. To this end, the proposed rule provides: ... Determination of vertical travel time for leaky confinement will be by application of the following formulae: Vv= Kv h/nl where: Vv= vertical velocity (feet/day). Kv= vertical hydraulic conductivities of the surficial aquifer and underlying confining bed materials (feet/day). h= head difference between water table in the surficial aquifer and the potentiometric surface of the producing aquifer (feet). n = effective porosities of the surficial aquifer and underlying confining bed materials. 1 = distance from the water table to the top of the producing aquifer (feet). Tv= 1/Vv 365 where: Tv= vertical travel time (years). 1 = same as above. Vv= same as above. The "Vv" formula and the "Tv" formula are valid formulae, and are commonly used by hydrogeologists to calculate the vertical velocity and vertical travel time of groundwater. As proposed, the formulae present a reasonable methodology for computing the vertical velocity and vertical travel time of groundwater if the well is producing from one aquifer. The formulae cannot, however, as hereafter discussed, be reasonably applied if tee well is producing from multiple aquifers or if another aquifer intervenes between the surf aquifer and the producing aquifer. While not the most prevalent occurrence in the state wells in the Middle-Gulf regions often do penetrate more than one aquifer and do produce water from more than one aquifer. The rule defines the "Kv" element of the "Vv" formula as the "vertical hydraulic conductivities of the surficial aquifer and underlying confining bed materials (feet/day)." This is a reasonable definition and will produce a scientifically valid result provided the well does not penetrate multiple aquifers. Should the well penetrate multiple aquifers, the values derived for vertical velocity ("Vv") and vertical travel time ("Tv") will not be accurate since the hydraulic conductivities of the intervening aquifers are not, by the rule definition, factored into the calculation of "Kv". Under such circumstances, whether an aquifer was classified as confined or leaky confined would not be determined by a valid "Kv" but, rather, by chance. Protestants also contend that the rule is vague, arbitrary and capricious because it does not specify the methodology by which "Kv" is to be calculated. There are, however, methodologies commonly accepted by hydrogeologists to derive a scientifically valid "Kv", whether the well penetrates one or more than one aquifer. The infirmity of the rule is not its failure to specify a methodology, but its to include data necessary to produce a meaningful result. The rule defines the "n" element of the Vv formula as "effective porosities of the surficial aquifer and underlying confining bed materials." This is a reasonable definition and will, though the application of commonly accepted methodologies, produce a scientifically valid result. 7/ The rule defines the element "Delta h" in the Vv formula as the "head difference between the water table in the surficial aquifer and the potentiometric surface of the producing aquifer (feet)", and defines the element "1" as the "distance from the water table to the top of the producing aquifer (feet)." These elements are utilized in the formula to calculate a gradient, and must be measured using the same points of reference to yield a meaningful result. To this end, the proof demonstrates that the definitions are reasonable since they utilize the same points of reference, and that when applied in accordance with accepted hydrogeologic practice will produce a scientifically valid gradient. (See Department exhibit 7). Protestants contend, however, that the definitions of "Delta h" and "1" are vague, arbitrary and capricious because they do not specify when the measurements should be made, do not define "producing aquifer", and do not define "top" of the producing aquifer. For the reasons that follow, Protestants' contentions are found to be without merit. While a water table is a dynamic surface subject to frequent, if not daily fluctuation, resulting from variations in rainfall and the demands of man, and while a potentiometric surface is likewise a dynamic elevation that changes with time and season, protestants failed to demonstrate that there was any particular date or dates that would be most appropriate to make such calculations. Rather, protestants contended that unless such measurements were taken contemporaneously, any derivation of "Delta h" and "1" would not be reliable. While such might be the case, the rule does not mandate a divergence from the accepted hydrogeologic practice of taking such measurements contemporaneously. While the rule does not define "producing aquifer," it is an accepted hydrogeologic term and not subject to confusion. The only confusion in this case was the introduction of the issue of multiple producing aquifers and protestants' contentions that this rendered the Vv formula vague, arbitrary and capricious since it did not factor in such a consideration. Protestants' contention does not, however render the term "producing aquifer" vague. The sole purpose of the Vv and Tv formulas are to determine whether the aquifer from which water is being produced is leaky confined. To establish this, the formulae are applied to calculate whether the vertical travel time is five years or less. If a well is withdrawing water from more than one aquifer it may be necessary to calculate Vv and Tv for each aquifer to discern which of those aquifers are within the 5 year vertical travel time threshold, and therefore subject to G-I reclassification. To this end the rule is not vague, and would adequately address the multiple producing aquifer scenario. While the rule doe not define "top" of the producing aquifer, this term is an accepted hydrogeologic term and is not subject to confusion. In application there may, however, be disagreements among hydrogeologists as to where this line should be established because geologic boundaries are fine gradations, and not sharp lines which would lend themselves to the designation of precise points of reference. This is not, however, a failure of the rule, but a peculiarity of nature, and is subject to scientific proof. Notably, protestants did not demonstrate that "top" of the producing aquifer could be defined with reference to a fixed point. Under the circumstances, "top" of the producing aquifer is a reasonable reference point. Zones of Protection Proposed rule 17-3.408 provides: Determination of the boundaries of the zones of protection shall be based on radii from the wellhead or wellfield (if closely clustered, so that the five year zones of protection are overlapping), measured in 200 feet for the inner zone and five years for the outer zone. The radius of the outer zone shall be determined using the following formula: QT 2 3.14 hn where Q = permitted average daily flow from the well (measured in cubic feet per day); T = five years (1825 days); 3.14 = mathematical constant pi; r = radius (feet); h distance from the top of the producing aquifer to the bottom of the hole (feet); n effective porosity. For the purpose of this calculation the following effective porosities for representative Florida aquifers will be used: Floridan .05 Sand and Gravel .2 Biscayne .15 Surficial .2 The Department shall use more site-specific values for "Q", "n", or "h" when available for designation of the zones of protection by the Commission. Proposed rule 17-3.403(8)(a) provides that the inner zone of protection shall be based on a radius from the wellhead or wellfilled, as appropriate, of 200 feet. While denoted as an arbitrary radius, the 200 foot radius was not derived without fact or reason. Rather, it was a result reached at the workshops after consideration of existing regulations that establish buffer zones of 200-500 feet between a public water supply and a pollution source. Conceptually, the 200 foot zone was adopted because it is so small and so close to the well that it essentially constituted a zone of protection of the well head by preventing contaminants from moving into the well opening directly or the annular space around the well casing. Accordingly, the 200 foot zone has a reasonable basis. Its actual delineation is, however, as flawed as that of the five year zone discussed infra. The "r" formula defines the outer zone of protection, and calculates it as a radius equal to the distance groundwater would flow in five years toward the well. The basis for the "r" formula is the formula used to calculate the volume of a cylinder. That formula, V = pi r2 h, yields a simple volumetric measurement without any consideration of velocity. By the introduction of the element "n" (effective porosity), the "r" formula introduces a velocity component which would, properly applied, produce a radius equal to the distance groundwater would flow in 5 years. 8/ As proposed, however, the rule would establish a meaningless line around a well. Under the proposed rule, the Department would calculate "r" based on specified effective porosities ("n") for the Floridan, Biscayne, sand and gravel, and surficial aquifers absent site specific data. The Department is, however, under no requirement to generate site specific data, and currently is mapping the Middle-Gulf region based on the values established by the rule. Absent chance, the areas mapped will bear no relationship to groundwater travel time. The lithology of an aquifer and the surrounding layers is varied and diverse, and directly affects the direction and velocity of groundwater flow. By assuming "n", the "r" formula ignores the varied lithology, and produces a radius that would seldom, if ever, represent the actual rate at which groundwater moved toward any well. 9/ The zone thus circumscribed is an illusion since the groundwaters and contaminants within it may move at a rate significantly greater than or less than 5 years travel time. Notably, the Department has conducted no study or test to validate its proposed methodology. The element "Q" in the "r" formula is defined as the "permitted average daily flow from the well (measured in cubic feet per day)." Protestants contend that such definition is vague, arbitrary and capricious because the Department proposes to rely on consumptive use permits issued by the various water management districts to derive "Q", and such permits would not necessarily provide the requisite data. While the proof demonstrates that "Q" cannot always be derived by reference to a consumptive use permit, this does not render the definition of "Q" vague, arbitrary, or capricious. Rather, "Q" is a factual matter, and subject to a factual derivation through reference to consumptive use permits and other site specific data. The element "T" in the "r" formula is defined as "five years (1825) days." By its inclusion, the Department proposes to circumscribe the outer zone of protection at five years groundwater travel time. The concept of a zone of protection is premised on the theory that restrictions should be placed on discharges to groundwater within an area proximate to a public water supply for public health and safety concerns. The five year standard, which is found throughout the rules, was based on the theory that if a contaminant was introduced to groundwater a period of time should be allowed to discover the contamination and remove it or make provision for an alternate water supply before the contaminant reached the public water supply. The five years proposed by the rule was not, however, founded on fact or reason. During the workshops that under scored the proposed rule, the time factor was the subject of considerable discussion and ranged from less than two years to greater than ten years. Based on its own in-house search, the Department initially proposed a 10-year standard. That search revealed that it took 10 to 15 years between the time a contaminant was discovered and cleanup could commence, and between seven and eight years between the time a contaminant was introduced into groundwater and it discovery. Notwithstanding the results of its own in-house search, the Department, in the face of debate, elected to "compromise" and propose a five-year standard. Such standard was not the result of any study to assess its validity, and no data, reports or other research were utilized to derive it. In sum, the five- year standard was simply a "compromise", and was not supported by fact or reason. As previously noted, the lithology of an aquifer and the surrounding layers is varied and diverse, and directly affects the direction and velocity of groundwater flow. The effective porosity of those materials in the Floridan aquifer canvary from to .4 at various places. The rule proposes, however, to use an effective porosity for the Floridan aquifer of .05 to establish "r." The value ascribed to "n" is a critical value, as previously discussed in paragraph 65. It also has a profound impact on the aeral extent of the zone of protection. For example, assuming "Q" equals 3 million gallons and "h" equals 600 feet, an "n" of .02 would result in a radius of 4,406 feet or 1,400 acres, an "n" of .03 would result in a radius of 3,578 fee or 934 acres, an "n" of .05 would result in a radius of 2,787 feet or 560 acres, and an "n" of .2 would result in a radius of 1,393 feet or 140 acres. While an effective porosity of 05 for the Floridan aquifer may be a reasonable value at a particular site, it is not a value that can be reasonably ascribed to the Floridan in general. For this reason, and the reasons heretofore set forth, the rule's specification of an effective porosity of .05 for the Floridan aquifer is unreasonable. Proposed rule 17-3.403(8)(a), sets forth the manner in which the zones of protection will be drawn around a well or wellfield. That proposed rule provides: For well fields whose individual zones of protection overlap due to clustering, a single zone of protection will be calculated in the following manner: Using the permitted average daily withdrawal rate of the wells with overlapping zones of protection, the area on the surface overlying the aquifer equal to the sum of the areas of the five year zones of protection of the individual wells, shall be used to define the area which encircles the perimeter of the wellfield. In cases where a zone of protection of a single well protrudues beyond the calculated perimeter or when the configuration of the wellfield is irregular, the perimeter will be shaped to accommodate the configuration. The surface are encircling the perimeter of the wellfield shall not exceed the total surface area of the overlapping zones of protection for individual wells. In the case of unclustered wells within a wellfield, individual zones of protection around each well will be calculated. As previously discussed, the proposed G-I rules are facially applicable to "community water systems" that hold a " consumptive use permit to withdraw an average daily amount of 100,000 gallons or greater of groundwater," and which are withdrawing from unconfined or leaky confined aquifers. Under proposed rule 1773.403(8)(a), the five-year zone of protection would be drawn around each of these wells. If the wells are located so close to each other that the five year zones of protection are overlapping (clustered), those wells would be deemed a wellfield by rule definition and a five year zone of protection would be established around it. The proposed rule's description at how to determine and configure a zone of protection around a wellfield is however, vague and ambiguous. While the rule provides that when the configuration of the wellfield is "irregular", the perimeter will be shaped to accommodate the configuration", it sets forth no standard by which the perimeter will be established. Effectively, the rule vests unbridled discretion in the Department to establish the configuration of a wellfield. The Economic Impact Statements Pursuant to the mandate of Section 120.54(2), Florida Statutes, the Department prepared economic impact statements for the proposed revisions to Chapters 17-3 and 17-4, Florida Administrative Code. The economic impact statements were prepared by Dr. Elizabeth Field, the Department's chief economist, an expert in economics. Dr. Field developed the economic impact statements by examining the proposed rules and discussing their potential impact with Department staff. Additionally, Dr. Field attended the public workshops that were held concerning the proposed rules, and solicited input from those participants. The Florida Home Builders Association and the Florida Petroleum Council submitted data for her consideration, but none of the petitioners, although some were represented at such workshops, responded to her requests for information. The economic impact statements prepared by Dr. Field to address the proposed rules conclude that, apart from the cost to the Department for mapping, there are no direct costs or economic benefits occasioned by the rules. Dr. Field's conclusion was premised on the fact that the proposed rules only establish the eligibility criteria for reclassification of an aquifer to G-I and the standards for discharge to that aquifer. Under the proposed rules, further rulemaking would be required to actually designate a specific aquifer as G-I, and delineate a zone of protection. 10/ Pertinent to this case, proposed rule 17-3.403, provides: The intent of establishing G-I eligibility criteria is to determine which aquifer or aquifer segments qualify for potential reclassification to G-I aquifers. Adoption of these criteria does not imply nor does it designate aquifer or aquifer segments as G-I. Such designation can only be achieved through reclassification by the Commission after eligible segments have been mapped by the Department. (6)... the following procedure shall be used to designate Class G-I aquifers: Rulemaking procedures pursuant to Chapter 17-102, F.A.C., shall be followed; Fact-finding workshops shall be held in the affected area; All local, county, or municipal governments, water management districts, state legislators, regional water supply authorities, and regional planning councils whose districts or jurisdictions include all or part of a proposed G-I aquifer shall be notified in writing by the Department at least 60 days prior to the workshop; A prominent public notice shall be placed in an appropriate newspaper(s) of general circulation in the area of the proposed G-I aquifer at least 60 days prior to the workshop. The notice shall contain a geographic location map indicating the area of the zones of protection and a general description of the impact of reclassification on present and future discharges to groundwater. A notice of a G-I workshop shall be published in the Florida Administrative Weekly prior to the workshop(s). At least 180 days prior to the Commission meeting during which a particular zone of protection will be considered for reclassification, the Department will provide notice in the Florida Administrative Weekly and appropriate newspaper(s) of the intended date of the Commission meeting. The Commission may reclassify an aquifer or aquifer segment as a G-I aquifer within specified boundaries upon consideration of environmental, technological, water quality, institutional (including local land use comprehensive plans), public health, public interest, social and economic factors. When considering a reclassification an aquifer or aquifer segment shall: ....(Be within the zones of protection of a major public community drinking water supply well(s) or wellfield(s) withdrawing water from unconfined or from leaky confined aquifers.).... Be specifically mapped and delineated by the Department on a detailed map of a scale which would clearly depict the applicable zones or protection. Maps will be grouped and submitted for reclassification generally on a regional basis. Mapping priorities shall follow the Commission directive of February 27, 1985. The remaining areas of the state will be mapped by the Department as time and resources allow. (Emphasis added). While, if and when applied, the proposed rules would certainly have a direct economic impact as a consequence of a reclassification of an aquifer to G-I and the designation of a zone of protection, as well as the standards for discharge to that aquifer, such costs at this stage are not direct or are not quantifiable. When mapped and the zones of protection identified, a reasonable assessment of the economic cost or benefit of the proposal can be addressed. This is specifically reserved by the Commission whereby its decision to reclassify an aquifer as G-I will, pursuant to proposed rule 17-3.403(6) follow rule making procedures and be based on consideration of economic factors. This result obtains whether the affected party is a small business or some other entity. In reaching the conclusion that the economic costs or benefits of the proposed rules, apart from the cost of mapping, do not at this stage have a direct or quantifiable impact, I have not overlooked the "announcement effect" that is occasioned by the announcement of a governmental agency to regulate an activity. Such announcement certainly has a chilling effect on the community that may reasonably be impacted. The economic impact is, however, speculative or not quantifiable in the instant case. Further, the proof does not demonstrate any incorrectness or unfairness in the proposed adoption of the rules occasioned by the EIS prepared in this case.
Findings Of Fact The Petitioner, Responsible Growth Management, Inc., is a not-for- profit corporation conceived and organized for the purpose of monitoring local governments within the geographic boundaries of Lee County for compliance with the requirements of the Florida Growth Management Act. Its members are residents of Lee County. Some of its members obtain their potable water from sources protected by Lee County Ordinance No. 89-30, as amended by Ordinance 90- 40 and 90-46, collectively referred to as the Wellfield Protection Ordinance (WPO). Other members obtain their potable water from sources the Petitioner contends are not protected by the WPO. The Petitioner contends that, for several reasons, the WPO is not consistent with the Lee County comprehensive plan. The Lee Plan Goal 41 of the Lee County comprehensive plan (the Lee Plan) provides in pertinent part: GOAL 41: GROUNDWATER. To protect the county's groundwater supplies from those activites having the potential for depleting or degrading those supplies. OBJECTIVE 41.1: WELLFIELD PROTECTION. By 1990 the county shall adopt a wellfield protection ordinance to provide regulations protecting the quality of water flowing into potable water wellfields. POLICY 41.1.1: The proposed wellfield protection ordinance shall be based on reliable technical data to ensure that adequate protection is provided. POLICY 41.1.2: The wellfield protection ordinance shall be amended whenever better technical data is developed and whenever additional potable wellfields are proposed. POLICY 41.1.3: The staff hydrogeologist shall review and comment on all development applications near public utility potable water wellfields, with particular attention to proposed land uses within a 10-year travel time from the well- heads. Goal 85 of the Lee Plan provides: GOAL 85: WATER QUALITY AND WASTEWATER. To ensure that water quality is maintained or improved for the protection of the environ- ment and people of Lee County.

POLICY 87.1.3: Freshwater resources shall be managed in order to maintain adequate freshwater supplies during dry periods and to conserve water. POLICY 87.1.4: Development designs shall provide for maintain- ing surface water flows, groundwater levels, and lake levels at or above existing conditions. POLICY 87.1.5: The county shall cooperate with the United States Geological Survey, South Florida Water Management District, and state agencies to develop an area-wide water resources plan emphasizing planning and management of water resources on the basis of drainage basins; and addressing the needs of the existing and potential built environment, natural hydro- logic system requirements, and freshwater flow impacts on estuarine systems. POLICY 87.1.6: The county shall continue to support a moni- toring program of existing baseline conditions of water resources. POLICY 87.1.7: The county shall cooperate fully with emer- gency water conservation measures of the South Florida Water Management District. The WPO Lee County Ordinance 89-30 provides for potable water wellfield protection. It establishes wellfield protection zones and sets out a protection zone map: showing the location on the ground of the outer limits of protection zones for present public utility potable water supply wells and wellfields which are permitted to pump 1,000,000 gallons of water per day or more. The Florida Cities-Waterway Estates Wellfield shall not be included within the protections established by this ordinance or depicted on the Protection Zone Maps. Chapter 10 of the ordinance is a "sunset provision" confirming that the ordinance was adopted "for the purpose of providing interim protection to existing potable water wellfields which are permitted to pump one million gallons of water or more per day" and explaining: The County is engaged in the creation of a Raw Water Management Authority to insure the protection of the public potable water supply. Potable water wellfields make up a portion of the available public potable water supply. In adopting this ordinace, the Board has taken the first step toward creating such an author- ity and providing an overall program for the protection of the public water supply. The wellfield protection ordinance is conceived as a part of that program. In order to insure that the wellfield protec- tion efforts of the County are incorporated into any overall program to protect the public potable water supply this ordinance shall expire and be of no further force and effect as to any acts occurring on or after September 1, 1991. The data and analysis supporting the Lee Plan clearly was based on the assumption of a 1 MGD threshhold. 5/ Section 4.05 of the Ordinance provides: Certain existing or proposed public and quasi-public land uses and activities may be declared exempt from the provisions of this Ordinance by the Board of County Commission- ers. This exemption shall be granted only upon a finding made by the Board in a public meeting that the existing or proposed land use or activity serves a public need which overrides the intent and purpose of this Ordinance and that it would be economically impractical or scientifically impossible for the land use or activity to comply with the requirements of this Ordinance or be relo- cated to an area outside of the protection zones established by this Ordinance. When declaring such an exemption, the Board of County Commissioners shall limit it to the extent necessary to enable the existing or proposed public or quasi-public land use or activity in question to be conducted within a protection zone while still serving the intent and prupose of this Ordinance to the extent which is economically practical and scientifi- cally possible. The Board may attach any con- ditions to the grant of any exemption that it deems appropriate. Section 3.01 of the Ordinance states: Four types of Protection Zone[s] have been established using scientific criteria relating to the physical characteristics of the water supply aquifer and the transport gradients caused by either natural forces or induced pumpage of the wellfields (see Appendix A)." The transport times associated with the Pro- tection Zones are designed so as to allow adequate time to carry out mitigating proce- dures to prevent wellfield contamination in the event of spillage of any Regulated Substance. Section 3.01.A. establishes and defines Protection Zone 1 as: "All land situated between the well(s) and the water table aquifer 6-month travel time zone demarcation." Section 3.01.B. establishes and defines Protection Zone 2 as: "All land situated between the well(s) and the planar geometric union of the largest of the following three travel time zones: Water table aquifer 1-year travel time zone demarcation. Lower Tamiami 1-year travel time zone demarcation. Sandstone 1-year travel time zone demarcation. Section 3.01.C. establishes and defines Protection Zone 3 as: "All land situated between the well(s) and the planar geometric union of the largest of the following three travel time zones: Water table 1-year travel time zone demar- cation and the water table aquifer 5-year travel time zone demarcation. Sandstone aquifer 1-year travel time zone demarcation and the Sandstone aquifer 5-year travel time zone demarcation. Lower Tamiami 1-year travel time zone demarcation and the Lower Tamiami 5-year travel time zone demarcation. Section 3.01.D. establishes and defines Protection Zone 4 as: "All land situated between the well(s) and the planar geometric union of the largest of the following three travel time zones: Water table 5-year travel time zone demar- cation and the water table 10-year travel time zone demarcation. Sandstone 5-year travel time zone demarca- tion and the Sandstone 10-year travel time zone demarcation. Lower Tamiami 5-year travel time zone demar- cation and the Lower Tamiami 10-year travel time zone demarcation. Section 3.02.B. of the Ordinance provides essentially that, where the location of property and buildings is within more than one protection zone, the most restrictive protective zone applies. Section 4.04 of the Ordinance prohibits liquid waste and solid waste disposal in Protection Zones 1, 2, and 3. In those zones, it also prohibits wastewater effluent disposal, except for public access reuse of reclaimed water and land application (under the conditions set forth and as defined in Chapter 17-610, Part III, F.A.C.). As for the exception, it provides: "Where public access reuse is permitted the chloride content shall be no greater than 500 mg/l." In Protection Zones 1 and 2, it also prohibits "the use handling, production, or storage of Regulated Substances [defined in Section 4.03 of the Ordinance] associated with land uses or activities regulated by this Ordinance in quantities greater than those set forth in Section 4.02.A." and "[e]arth mining within a five hundred foot (500') radius of an existing wellhead." The only prohibition in Protection Zone 4 is against "any activity regulated by this ordinance which stores, handles, uses, or produces any Regulated Substance, in quantities greater than those set forth in Section 4.02.A., which does not obtain a valid operation permit as set forth in Section 6.02." Thus, the Ordinance does not by its terms prohibit landfills, sludge disposal or rapid rate percolation ponds in Zone 4. Section 4.03 of the Ordinance, entitled "Regulated Hazardous or Toxic Substances," defines regulated substances in part in terms of federal and state regulations that are referenced, but not reproduced, in the ordinance. Section 4.02 of the Ordinance provides that it applies only to a particular land use or activity, whether that land use or activity is classified as a residential or commercial use, when either the aggregate sum of all quantities of any one Regulated Substance, or the aggregate sum of all Regulated Substances, on a given parcel or in a certain building exceeds one hundred and ten (110) gallons if the substance is liquid, or one thousand, one hundred and ten (1,110) pounds if said substance is solid. It also provides that the Ordinance applies to all storage facilities for petroleum products which are not regulated by Section 376.317, Florida Statutes, or Chapter 17-61, Florida Administrative Code. Section 4.04 of the Ordinance also provides that, within the protection zones: "Any stormwater or surface water discharge . . . shall conform to existing S.F.W.M.D. and F.D.E.R. rules or as they may be amended or replaced." Under Section 4.04 of the Ordinance, "partially treated sewage from residential septic tank systems" are not regulated in any of the protection zones. Section 4.05.B.5. of the Ordinance provides an: Exemption for Retail Sales Activities. Retail sales establishments that store and handle Regulated Substances for resale in their original unopened containers shall be exempt from the prohibition in Sub-Sections 4.04.A.1. and 2. provided that those estab- lishments obtain an Operating Permit pursuant to Section 6.02. No operating permit is re- quired in Protection Zones 3 and 4. Other Relevant Facts The WPO's Coverage. The support documentation in support of the Lee Plan was based on the assumption of a 1 MGD threshhold. The evidence as a whole does not suggest that was it contemplated at any time prior to adoption that the Lee Plan would require a wellfield protection ordinance that protects all potable water wellfields. 6/ Although the documentation in support of the Lee Plan focuses on wellfields permitted to pump 1 MGD or more and serves an indication that the Lee Plan does not require all potable wellfields to be covered by a protection ordinance, nothing in the Lee Plan or the supporting documentation establishes a clear intention to require the same protections for all wellfields permitted to pump 1 MGD or more. The focus of the WPO is on the protection of wellfields from contamination from the ground surface. Two wellfields permitted to pump more than 1 MGD are not covered by those protections. They pump from deep aquifers. The confining layers above those aquifers protect them from contamination from the ground surface. Other parts of the WPO, and other regulatory programs, require that abandoned wells that could possibly serve as a conduit for contamination into those aquifers be properly grouted so as to prevent contamination from the ground surface. As a result, they are adequately protected. 7/ The Florida Cities-Waterway Estates wellfield pumps from both the surficial aquifer and from a deeper aquifer known as the mid-Hawthorn. The confining layers above the mid-Hawthorn aquifer protect it from contamination from the ground surface. Other parts of the WPO, and other regulatory programs, require that abandoned wells that could possibly serve as a conduit for contamination into the mid-Hawthorn be properly grouted so as to prevent contamination from the ground surface. As for the wells pumping from the surficial aquifer, no party presented evidence on which findings of fact can be made on the issue whether it is fairly debatable to exclude the Florida Cities- Waterways wellfield from the WPO's protections against contamination from the ground surface. There was no evidence on which a finding can be made as to why they were excluded from the greater protections the WPO affords to other wellfields permitted to pump 1 MGD or more. 8/ The evidence was that 90% to 95% of Lee County's potable water supply is either covered by the WPO, with its 1 MGD threshhold and exclusion of the Florida Cities-Waterway Estates wellfield, or pumps from deep aquifers that do not need the WPO's protections from contamination from the ground surface. The Department of Environmental Regulation's so-called G regulations adopted in 1986 utilize a 100,000 gallon a day threshhold for coverage. This threshhold was selected to coincide with the jurisdiction of, and to extend coverage to all wells requiring a permit from, Florida's water management districts. The G-I regulations were successfully challenged and still are not in effect. The federal Environmental Protection Agency recently has criticized the G Although it is written in general terms to leave open the possibility of other similar applications, the evidence reflects that the primary purpose of the Section 4.05 exemption for "certain existing or proposed public and quasi- public land uses and activities" is to acknowledge and permit consideration to be given to the practical impact of possible future expansion of the regional airport located in Lee County. Since there are wellfields in the vicinity that possibly could be impacted by such an expansion, the exemption acknowledges that it might be more sensible, feasible, practical and economical to replace the wellfields than to move the regional airport. If this happens and, on a case- by-case basis, the County utililizes the exemption provision, it may be necessary to phase out the wellfields and to allow some degradation of parts of the wellfield, subject to close monitoring pending complete replacement of the wellfields. Alleged Inadequate Regulation of Pollution Sources. Rock and sand mine operations, which are prohibited within 500' of a wellhead, create open, water-filled holes in the ground. As the Petitioner correctly points out, mining operations can thereby create direct conduits that can lead contaminants to underlying aquifers. But there is evidence in the record to justify the WPO's treatment of rock and sand mines on several bases: first, these mines are regulated on a case-by-case basis through a permitting process; second, mines that have been permitted are relatively shallow and reach into, but do not penetrate, the layer confining the aquifers in the vicinity of the mines that are sources of potable water; third, the County has required as a condition of these permits that the pits be prohibited from serving as storm water retention ponds in the future so as to prevent contaminants from gaining entry to the potential conduit; and, finally, the evidence provides assurances that, even if contaminants somehow find their way into the pits, their concentrations would be low enough that sufficient "head" to penetrate the confining layers would not be generated. The WPO does not prohibit "zones of discharge." A "zone of discharge" is a deliberate decision on the part of a regulatory agency to utilize a limited part of the groundwater as part of the process of diluting contaminants. There was some expert testimony that, in a general and theoretical or academic sense, the concept of a "zone of discharge" is inconsistent with wellfield protection. They are not permitted in DER's G The WPO permits landfills, sludge disposal and rapid rate infiltration ponds in Protection Zone 4 (delineated by the ten-year travel time). The evidence was that landfills, at least, are subject to Department of Environmental Regulation (DER) and other regulation and permitting requirements that would provide adequate wellfield protection. There was no evidence or argument presented by any party to clarify how the other activities--sludge disposal and rapid rate infiltration ponds--are regulated. The Petitioner's evidence in general did not address the existence or absence of regulations (both County and other regulatory agencies) pertaining to the various activities of which it complains to rule out the possibility that they might meet the objectives and policies of the Lee Plan. The WPO does not contain its own stormwater regulations. Instead, it provides: "Any stormwater or surface water discharge . . . shall conform to existing S.F.W.M.D. and F.D.E.R. rules or as they may be amended or replaced." The Petitioner offered, as evidence in support of its position that the DER and SFWMD stormwater regulations are inadequate, expert testimony to the effect that the DER and SFWMD regulations are "performance standards," not "directed to groundwater monitoring, and it's not quality impact related." A "performance standard" requires certain things to be done with stormwater in the expectation that groundwater contamination would be eliminated or minimized. The Petitioner's witnesses related that DER decided that "protection of public water supply has to be protected to above and beyond a performance standard" and opted for specific water quality criteria in its G-I groundwater. But nothing in the Lee Plan requires utilization of the G-I rule approach, and the Petitioner's expert did not opine that failure to do so would render the WPO inconsistent with the Lee Plan. The Section 4.05.B.5 retail sales exemption presents a risk of contamination of a wellfield, but the risk is low. In all likelihood, it would take a fire or some other similar catastrophe for the possibility of actual harm to a wellfield to materialize from the small risk involved. Other County Measures Relevant to the WPO. The County has several programs, other than the WPO, and in addition to the Raw Water Management Authority mentioned in the WPO, 9/ that impact wellfield protection. It has a program to encourage (and in some cases require) the reduction and elimination of the use of septic tanks and package sewage plants. It is building a new sewer district. It has taken over the from DER the function of inspecting the installation of underground storage tanks and the remediation (clean up and repair) of tanks storing liquid petroleum products in an attempt to do the job better. There also was evidence that the County has restricted density in potential future wellfield locations and their recharge areas to one unit per ten acres. (The Petitioner's own witness testified that, other than an outright ban on septic tanks, density reduction is the only way to address the problem of septic tanks.
The Issue As reflected in the parties' prehearing stipulation filed on August 28, 1991, the issue in this case is whether the St. Johns River Water Management District (SJRWMD) should approve South Brevard Water Authority's (SBWA) consumptive use permit (CUP) application. The SBWA is seeking permission to withdraw an annual average daily rate of 18.8 million gallons (mgd) and a maximum daily rate of 21.4 mgd. The District proposes to grant the permit with specified conditions. Petitioners challenge the issuance of the permit, alleging that applicable requirements of Chapter 373, F.S. and Chapter 40C-2, F.A.C. and other applicable law are not met. The standing of Petitioners, other than Osceola County, is at issue. Also at issue is whether the relevant criteria include consideration of the adequacy of existing sources of water, and the consideration of costs of utilizing existing sources versus the cost of the proposed new source of water.
Findings Of Fact The Parties The applicant, South Brevard Water Authority (SBWA) was created by special act of the legislature, Chapter 83-375, Laws of Florida. Its principal office is located in Melbourne, Brevard County, Florida. Its general mission is described in Section 1, of Chapter 83-375, Laws of Florida, as amended by Chapter 87-481, Laws of Florida: Section 1. It is hereby declared and determined by the Legislature that a regional water authority is the most responsive, efficient, and effective local government entity to secure, operate, and maintain an adequate, dependable, and safe water supply for the district and customers of the district. It is the intent of the Legislature that such regional water authority possess the full power and authority to implement, finance, and operate a single coordinated program of water supply transmission and distribution to meet the future quantity and quality needs of the district and for customers of the district. There is a paramount public need to develop a safe, reliable, and energy-efficient source of public water for the district residents and to contruct the wellfields, transmission lines, and other facilities necessary to supply such water. The St. Johns River Water Management District (SJRWMD or District) is an agency created pursuant to Chapter 373, F.S. in charge of regulating consumptive uses of water in a 19-county area of the State of Florida, including all of Brevard and part of Osceola County. The geographical boundaries of the District are described in Section 373.069(2)(c), F.S. Osceola County is a political subdivision of the state, west of, and contiguous to, south Brevard County. The Corporation of the President of the Church of Jesus Christ of Latter Day Saints (Deseret) is a Utah corporation authorized to conduct business in the State of Florida. Deseret owns real property in Osceola County to the north and east of the proposed wellfield. Deseret possesses a valid consumptive use permit authorizing the withdrawal of water for this property. East Central Florida Services (ECFS) does not own land or possess a consumptive use permit (CUP). Its purpose is to take over the water management program for the Deseret property. It has applied to the Public Service Commission for certification. Notwithstanding the parties' stipulation that "Triple E Corporation" and "Triple N Corporation" own real property in Osceola County near the proposed wellfield (prehearing stipulation, filed 8/28/91, p. 5), no such corporations are registered in the State of Florida. The lands identified as Triple E and Triple N are owned by multiple parties through trusts, primarily managed by Maury L. Carter, one of the owners. Neither Triple E nor Triple N properties have CUP's. The properties are used for agricultural purposes and the Triple N property has a well and recreational camp. The Site of the Proposed Use The proposed wellfield is located on property owned by the SJRWMD, the Bull Creek Wildlife Management Area (BCWMA), located entirely in eastern Osceola County. The BCWMA is comprised of 22,206 acres within the drainage area of the St. Johns River. The northern third of the management area is drained by Crabgrass Creek, and the southern two-thirds is drained by Bull Creek. The easternmost boundary is located approximately one mile from the Brevard County boundary. Currently all 22,206 acres of the BCWMA are under lease to the Florida Game and Fresh Water Fish Commission, which agency manages the area as a public recreation facility for hunting, fishing, hiking, horseback riding, camping and archeological studies. The sparsely populated area has historically been used for logging and cattle grazing. It was acquired for a detention area and it currently provides nonstructural flood protection. Its surface topography is relatively flat, with uplands and wetlands separated by only inches in vertical elevation. Upland communities include pine flatwoods, saw palmetto prairies, pine savannahs and sand oaks. Wetland communities include cypress domes, mixed shallow marshes, sawgrass marsh, wet prairies and transitional prairies. The BCWMA is classified as a "conservation area" in the District's current adopted Five Year Land Plan which summarizes the agency's land acquisition and management policies. A "conservation area" is defined as "...an area acquired for water resource conservation and protection in an environmentally-acceptable manner". The term includes water supply areas, including areas for public wellfield location. (Osceola Co. exhibit #33, p. 15) Facilities Associated with the Proposed Consumptive Use Although the precise siting of the wells has not been established, the wellfield will be located at the northern end of the BCWMA, east-west into a "panhandle" area, and extending south, for an inverted "L" shape. The wellfield will consist of 12 production wells in 2000 ft. intervals. Wells 1-9 will lie along an east-west axis adjacent to Crabgrass Creek, while wells 10-12 will lie along a north-south axis below well 9, the eastern-most well. The capacity of each well is designed at 3,000 gallons per minute or approximately 4.30 million gallons a day (mgd). Each well consists of 20" diameter casing pipe extending 700' below the ground surface. From there, an open hole for production will extend another 250 feet in depth. A small, 20 ft. by 30 ft., concrete building will enclose the motor and other equipment associated with each well, in order to eliminate vandalism and to baffle the noise. The wells will be sited to avoid jurisdictional wetlands. In addition to the production wells, monitoring wells will be constructed to comply with permit conditions. Because the water drawn from the proposed wellfield will exceed potable standards, reverse osmosis (RO) desalinization treatment is required. A below ground header pipeline will carry raw water from the wellfield to an RO treatment facility in Brevard County. The RO treatment facility will process 75 percent of water coming from the wellfield, 85 percent of which is recovered as finished water, and 15 percent of which is disposed of as brine by deep well injection. The 25 percent of raw water which bypasses the treatment process will be blended with the finished water to yield water which meets drinking water standards for chloride levels. The yield is anticipated to be 16.67 mgd on an average day and 18.9 mgd on a maximum day. However, the finished water yield could be higher if raw water quality permits greater blending and less reject water. On the finished water side, the water will need to be treated again to assure that it will be compatible with water from the City of Melbourne plant. Failure to balance the blended waters chemically could result in corrosion of pipes, leaching of pipes, discoloration, rusty water, and odorous water. A proper process, therefore, is essential and is highly sophisticated. From the treatment facility the water will travel in underground pipes, beneath the St. Johns River, beneath I-95 and east to the Melbourne distribution system. From there some water is anticipated to travel south to connect to the General Development Utilities (GDU) system. Hydrogeologic Characteristics of the Site For modelling purposes, the aquifer system in the region is represented by sequential layers of differing characteristics in the flow and movement of water. The SBWA model contains 6 layers; the Osceola model contains 7 layers. In both models, layer 1 corresponds to the surficial (water table) aquifer; layer 2 corresponds to the Hawthorn formation (the upper confirming layer); layer 3 is the Upper Floridan aquifer; layer 4 describes the 200 ft. thick portion of the Upper Floridan called the "production zone"; layer 5 in the SBWA model is approximately 450 ft. thick and is called a confining unit; Osceola's consultants consider this layer less permeable or semi-confirming; layer 6 is the lower Floridan; and layer 7 in the Osceola model is the bottom reaches of the lower Floridan. The surficial aquifer consists of sand and shell deposits and extends to a depth of approximately 100 feet below land surface. The surficial aquifer is capable of producing small to moderate amounts of water for domestic uses. The Hawthorn is an interbedded formation consisting of clay, limestone and phosphate. Due to its extremely low permeability, this layer restricts both the vertical and horizontal movement of water. The Hawthorn is thicker in Central Florida than in other portions of the state. At the BCWMA the thickness of the Hawthorn ranges from 240 feet in the area northwest of the management area to 80 feet in the southeastern portion of the management area. The upper Floridan Aquifer at the BCWMA, as characterized by the SBWA's consultant and based on site specific data, extends from the base of the Hawthorn to a depth of approximately 900 feet below land surface. That portion of the upper Floridan Aquifer between the bottom of the Hawthorn and 700 feet below land surface consists of fine grained limestone with relatively low permeability. This zone corresponds with layer 3 in the groundwater modeling done by the SBWA. The portion of the upper Floridan between the bottom of the Hawthorn and 700 feet below land surface is less capable of producing water than the portions below this level. That portion of the upper Floridan Aquifer between 700 feet and 900 feet of depth consists of hard dolomites. Dolomitic zones are the most productive zones of water within the Floridan in this part of the state because these formations contain solution fractures and cavities. This zone corresponds with layer 4 in the groundwater modeling done by the SBWA. Several researchers and modelers have suggested the existence of a zone, variously referred to as a semi-confining unit, a zone of lower permeability or a middle semi-confining unit, located between the upper and lower Floridan Aquifer. This area between 900 feet and 1350 feet below land surface consists largely of hard dolomites similar in nature to those in the zone immediately above it. This zone corresponds to layer 5 in the groundwater modeling done by SBWA. Previous regional modeling efforts have utilized model derived values to describe the middle semi-confining unit rather than site specific information showing the location, thickness or hydrogeological characteristics of the zone. Site specific data tends to confirm the lower permeability of this zone relative to the layers above and below it. Site specific data consists of a core sample, mineral content observed during the drilling of the test monitor well, and a Neumann-Witherspoon ratio analysis conducted during the aquifer performance test. The area between 1350 feet and 1450 feet below land surface also consists of dolomites but with greater permeability and greater transmissivity (the measure of an aquifer's ability to transmit water in a horizontal direction). This area corresponds to layer 6 in the groundwater modeling done by the SBWA. No site specific data exists beneath 1483 feet, representing the total depth of test well TM. Regional data does exist which characterizes the areas from 1500 feet below land surface to the bottom of the lower Floridan Aquifer as consisting of zones of varying lithology, and varying permeabilities. This zone which corresponds to layer 7 in the groundwater modeling done by Osceola County is not homogeneous or uniform over its entire thickness according to available regional data, consisting of geologic reports of deep wells in the east-central Florida area. All parties agree that in the area of the proposed wellfield, horizontal movement of water in the Floridan aquifer is from west, where the greatest recharge occurs along the Lake Wales Ridge, to east, where there is little or no recharge. Water quality in the upper Floridan as measured by chloride concentrations deteriorates as one moves from west to east. The Floridan aquifer beneath the BCWMA represents a transition zone between the recharge area to the west and high saline formation waters in the east. The dominant geochemical components in water beneath the BCWMA are biocarbonates. Water quality, as measured by chloride concentrations, also deteriorates with depth. Chloride concentrations, based on data derived from the drilling of well TM at the BCWMA, increase gradually from 306 milligrams per liter (mgl) at 410 feet, to 658 mgl at 1473 feet below land surface. Chloride concentrations increase abruptly to 1980 mgl in well TM at 1483 feet of depth. Evidence is inconclusive as to whether all of the proposed production wells will draw water exceeding 250 mgl in chloride concentrations. It is undisputed that most will, but chloride contours initially provided by SBWA's consultant indicate that the southernmost wells may produce water between 150 and 250 mgl. A comprehensive aquifer performance test (APT) was conducted at the BCWMA by the SBWA's consultant, Post, Buckley Schuh, and Jernigan, Inc. (PBSJ). The test was designed by the staff of the SJRWMD in consultation with the U.S. Geological Survey (USGS). This test yielded data which enabled PBSJ to calculate several aquifer characteristics for use in the groundwater modeling which was later done by SBWA's modeling consultant, Environmental Science and Engineering, Inc. (ESE). Eight wells were utilized in connection with the APT conducted at the BCWMA in January and February 1990. Three of the wells were dual zone monitoring wells capable of monitoring events in two different geologic units simultaneously. Three wells, including the test production well (TP) were open to the interval between 700 and 900 feet below land surface which was identified by the SBWA as the production zone. Typically APT's are run for 12 to 72 hours in Florida. Well TP was pumped for approximately 10 days at a rate equivalent to that expected during actual production while observations were made of water levels in all wells, including three off-site wells (the Holopaw test well, the Kempfer well and the Bruner well). All of the information the SBWA needed from the APT was obtained in the first hours of the test. Water levels in the area monitored during the APT ceased dropping due to pumpage within 1 hour after the pumping started. Three different analytical models were used to calculate a transmissivity value for the production zone, utilizing data derived during the APT. The result showed transmissivity in this zone to be approximately 2 million gallons per foot per day. This is a very high transmissivity value indicating a comparatively prolific aquifer, capable of producing the volumes of water requested in the application. As transmissivity increases, the cone of depression associated with pumpage tends to flatten out and be less steep. The cone of depression extends further out, creating a wider area of drawdown. Hydraulic conductivity is the measure of an aquifer's resistance to flow either in a vertical (KV) or horizontal (KH) direction. Two methods were used to calculate the hydraulic conductivity of the Hawthon Formation by PBSJ: laboratory analysis of a core sample taken from this unit, and a bail test (measuring an increase in water level over time) conducted on a well on site by the SJRWMD. Two different methods were used by PBSJ to calculate the hydraulic conductivity of layer 5: laboratory analysis of a core sample taken from that zone, and the Neuman-Witherspoon ratio analysis method. Porosity is the void space in porous media through which transport of particles, such as chlorides, can occur. Effective porosity has an impact on the ability of saline or dense water to move upward from depth toward a pumping well. The lower the effective porosity within an aquifer, the greater the potential for upconing of saline water within that aquifer. Effective porosity for layers 4 and 5 was calculated using two different methods, those being laboratory analysis of core samples taken from these zones, and analysis of acoustic logs generated during the APT. Each of these methods is accepted in the field of hydrogeology. Anticipated Impacts to Groundwater Levels and Flows as a Result of the Proposed Consumptive Use A numeric groundwater flow model is a computer code representing the groundwater flow process. Both SBWA and Osceola used numeric groundwater flow models developed by their consultants to predict and simulate the impacts associated with withdrawals proposed in the application. The SBWA used a finite difference model called INTERSAT for its simulations. INTERSAT is a widely used and accepted groundwater flow model. The model was run by ESE for the SBWA in the impact or drawdown mode. Drawdown or impact models simulate changes in water levels in response to a stress such as a pumping well. Drawdown models are an accepted and frequently used method to evaluate wellfield stress, particularly in association with a CUP application. ESE and PBSJ utilized several analytical models to first determine and later to verify the area to which the boundaries of their model would extend. The radius of influence of a well or wellfield is the distance from the center of pumpage extending out to where drawdowns caused by that pumpage reach zero. The boundary for a numeric groundwater model should be set at, or beyond, the radius of influence of the pumpage being simulated by the model. Based on the analytical models run by ESE and PBSJ the radius of influence of the wellfield proposed in the application is 43,000 to 45,000 feet. The approximate distances of the boundaries set in INTERSAT model from well TP were 50,000 feet to the east, 40,000 feet to the west, 40,000 feet to the north and 50,000 feet to the south. The INTERSAT model covers a total area of 320 square miles. This size falls somewhere between a regional model and a local model, and is adequate in size to address the impacts associated with the proposed withdrawals. The vertical boundary of SBWA's model extends to 1450 feet below land surface and, as stated above, is divided into 6 layers. The 1450 feet depth generally coincides with the limits of site specific data generated during the APT. The six layers in the SBWA flow model coincide with the six distinct geologic units identified by PBSJ in their APT report. The site specific data generated by the APT was utilized, along with other regional modeling studies, to arrive at a set of "conservative" aquifer parameters to be utilized in the INTERSAT model. "Conservative" parameters for purposes of this application are those which would tend to overpredict drawdown in the surficial aquifer and the production zone, while allowing for more upconing of dense water from the bottom of the model. The selection of "conservative" aquifer parameters by SBWA involved taking site specific values, comparing them with the ranges of values reported in the other available regional models and selecting values which, while still within the range of reported values used in other studies, would tend to show greater impacts for the areas of primary concern than the site specific values. Every aquifer parameter utilized in SBWA's groundwater flow model falls within the range of values reported in at least one of the groundwater modeling studies previously done in this region. The size of the grids utilized in the SBWA model were 500 feet by 500 feet within the vicinity of the wellfield. Grid sizes expand as one moves toward the outer boundaries of the model. The fineness of the grids used by ESE, particularly in the wellfield area, allows for accurate representation and resolution of surface water features, impacts in the production zone and for evaluating the effects of saltwater upcoming in the transport model also done by ESE. Within the radius of influence of the proposed wellfield, there are no existing wells in layers 5 or 6. The ESE model simulations for 18.8 mgd pumpage predict a maximum drawdown in the surficial aquifer (layer 1) of 0.14 feet centered primarily within the BCWMA. At a distance of 1 mile from the wellfield the impact drops to 0.12 feet. None of the existing legal users of water in layer 1 within the radius of influence of the proposed wellfield will suffer a ten percent or greater reduction in withdrawal capacity from their wells solely as a result of the proposed withdrawals, since 10 percent reduction would require at least 3 feet of drawdown. The ESE model simulations predict a maximum drawdown caused by the proposed pumpage of 4.5 feet in layer 3 centered along the alignment of wells and primarily within the BCWMA. At a distance of 2 miles, the drawdown drops to 2 feet. At the Brevard-Osceola County line the drawdown in layer 3 is approximately .5 feet. Petitioner Deseret's flowing wells are drilled in layer 3 and are located within the area where a drawdown of 1 foot is predicted in layer 3 by the ESE model. Deseret uses its property for a cow/calf ranching operation and has approximately 32,000 head of cows. Deseret uses 39 flowing wells east of state road 192 to irrigate pasture, water cattle and supply drinking water. Deseret possesses a valid CUP for a portion of the total flow capacity from those wells. Seasonally, the wells flow at different rates, but they are most relied upon in dry conditions when the natural flow would be decreased. It is unlikely that the proposed SBWA withdrawals will stop the flow of any of Deseret's wells; and it is unlikely that the flow will be reduced by more than 10 percent. Deseret and Osceola's consultants do predict a greater drawdown and opine that approximately 12 of Deseret's wells will cease flowing as a result of the SBWA withdraw As addressed below, the modelling by Petitioner's consultants, upon which those predictions are based, is less reliable than that of SBWA's consultants. If the effects are greater than predicted, mitigation in the form of installation of pumps is possible, albeit inconvenient and expensive. Mitigation would have to be provided by the applicant, SBWA. The drawdowns predicted by the ESE model for layer 4 are not significantly different from those for layer 3. It is anticipated that no legal user of water within the radius of influence of the proposed wellfield will suffer a 10 percent or greater reduction in withdrawal capacity for its wells, as a result of SBWA's proposed withdrawals. Petitioners' consultants, Hartman and Associates, (Hartman) modeled a significantly larger (4900 square miles) and deeper (3000 feet) area than did SBWA. The model makes its predictions based on one data point for every 49 square miles within the modeled area. Petitioners utilized much larger model grids in the wellfield area (2000 feet by 2000 feet) than did the SBWA. Grid of this size lacks the resolution necessary to evaluate wellfield impacts. Petitioners selected their aquifer parameters from another regional modeling study done in 1985 rather than using site specific data. Those parameters were then adjusted or calibrated until a match was obtained to a computer created potentiometric surface which was supposed to reflect the potentiometric surface for May 1990, an uncharacteristically dry period. The created potentiometric surface to which Hartman calibrated its model varies greatly from the potentiometric surface as reflected in the actual data points from which USGS derives its potentiometric surface maps. While no model is perfect, and actual data is preferable, in the absence of all the actual data that is needed, the ESE model is a more credible predictor of drawdowns. Anticipated Impacts to Groundwater Quality as a Result of the Proposed Consumptive Use Solute transport models are computer models designed to simulate the movement of mass, in this case -- chlorides -- through a groundwater flow system. These models are linked to, and are dependent on flow fields generated by groundwater flow models. In order to predict changes in water quality anticipated to occur as a result of its proposed withdrawals, SBWA's consultants used a solute transport model called HST3D. Developed by the USGS, this model is widely used and accepted. For simulations using the HST3D model, SBWA used the flow field and a portion of the grid generated by its INTERSAT groundwater flow model. The HST3D simulations run by ESE utilized a cross section of the INTERSAT model grid extending through row 26 of that grid, which is the row containing the line of 9 proposed wells running on an east-west axis. Use of a cross sectional grid is an appropriate method by which to examine salt water intrusion. Upconing, to the extent that it will occur as a result of the proposed pumpage, would be greatest within the cross section containing the 9 wells. The cross section extends two miles through the wellfield to the west. As chloride concentrations in water increase, the density of the water increases. Density can retard the degree of upconing when chloride concentrations are as low as 1000-2000 parts per million and becomes significant at 3000-5000 parts per million. Failure of a model to consider density effects, when appropriate, would tend to overstate upconing. HST3D does consider density effects. SBWA's consultant ran several simulations with the HST3D model to predict changes that would occur as a result of the proposed pumpage in chloride concentrations over 7, 14 and 30 year time periods. These simulations utilized the same aquifer parameters as the INTERSAT model together with the effective porosity values derived from site specific data. Assuming a starting chloride concentration of 1000 mgl at the bottom of layer 5, the measured concentration at that level in well TM on the BCWMA site, after 30 years of pumpage at 18.8 mgd, the chloride concentrations in layer 4 would increase by only 100 mgl. The simulations for 7 years of pumpage which is the duration of the proposed permit, show that the predicted increase in chloride levels would be substantially less than 100 mgl. Other HST3D simulations were run by SBWA for a pumpage rate of 35 mgd utilizing beginning chloride concentrations of 5,000 mgl and 10,000 mgl, respectively at the bottom of layers. The results did not show any significant changes in chloride concentrations in layer 4 over and above those shown when a lower starting chloride concentration was assumed. In a circumstance where, as here, the chloride concentrations in the zone from which water is proposed to be withdrawn exceeds secondary drinking water standards (250 mgl), the SJRWMD evaluates the existing legal water uses within the area that would be impacted by the proposed use. If it is determined that the increase in chloride concentrations caused by a proposed use would detrimentally affect other existing legal users or the applicant, only then is the increase deemed to be "significant". Within the layers of the aquifer which would experience increases in chloride concentrations as a result of the proposed withdrawal, layers 4, 5 and 6, no existing users of water would be detrimentally affected. Petitioner Deseret's closest wells to the proposed wellfield are in layer 3 where chloride levels will not be affected by the proposed wellfield within the 7 year duration of the proposed permit or even beyond that period. Further, the use Deseret makes of the water from the wells in closest proximity to the proposed wellfield, pasture irrigation, can tolerate significantly higher chloride concentrations than will exist even directly beneath the wellfield in level 4 after 30 years of pumping. Use of water for public supply purposes is considered by SJRWMD to be in the public interest. Utilization of the water beneath BCWMA for public supply purposes, even with some increase in chloride concentrations in the source of the water over the life of the permit, does not on balance detrimentally affect the public interest. Two different solute transport models were done by Petitioners' consultants, one a numeric model and the other an analytical model. The numeric model done by Hartman, RANDOMWALK, does not predict changes in chloride concentrations within an aquifer, but rather tracks movement of particles. RANDOMWALK does not account for density effects. The analytical model done by Prickett for the Petitioners relies on assumptions, many of which are not met in the aquifer system at BCWMA. Those assumptions relate to uniformity of the system, for example: porosity and permeabilities, and lack of regional gradients. The solute transport models utilized by the Petitioners are less reliable for predicting water quality changes resulting from the proposed pumpage than the model utilized by the SBWA. Salt water intrusion is a dramatic increase of chloride levels in an aquifer layer. The saline water encroachment which occurs from the wellfield stress will be in the lower confining unit. There will be limited degradation in the lower part of the production zone. The wellfield will not induce significant lateral intrusion from the east. There will not be any dramatic changes in chlorides. The movement of the chlorides is confined to the locality of the wellfield. Most of the movement is vertical and is of limited increase. The proposed Bull Creek withdrawals will not aggravate any currently existing salt water intrusion problems. The reject brine water from the RO treatment plant will be disposed of in deep injection wells in Brevard County. These injection wells would deposit the brine into a receiving body of water in the Oldsmar geologic formation. The brine reject will have a total dissolved solids (TDS) concentration of approximately 7,000 mgl. The receiving water into which the brine will be injected approximates sea water, with TDS concentrations in the range of 36,000 mgl. The receiving body will obviously not be further degraded. Environmental Impacts of the Proposed Consumptive Use District staff, SBWA consultants and Osceola's consultants independently conducted onsite field investigations of the BCWMA to evaluate the vegetative communities and land uses which exist on site. Each consultant prepared a habitat map identifying the various vegetative communities found at the site. While relatively pristine, the BCWMA has been logged and grazed by cattle in the past. The impacts of man's activities have been remediated by ceasing the activity. There are few permanent incursions, such as roads, canals and buildings. The area is a very diverse landscape, with a mosaic of different types of plant communities. There are various upland and wetland habitats. The variety of wetlands are forested and non-forested, deep and shallow, open and closed. These wetlands perform important functions, including water storage and purification, aquifer recharge, flood control, and provision of food sources and habitat for wildlife, and they are "factories" for producing the materials needed by many higher organisms. The wetlands on site are structurally complex and are good habitat for macro- invertebrates and the fish and higher organisms that feed on them. A number of these wetlands are shallow, isolated wetlands. During periods of inundation, when the wetlands fill up with water and interconnect with the Bull Creek drainage system, the system exports various organisms to the wetlands. Fish that are live bearers move into isolated wetlands during periods of inundation, and they and their offspring become a source of food for birds. Fish species that lay eggs can withstand desiccation (total drying out) can survive the temporary drying of wetlands, but live bearers must repopulate during periods of inundation. The mixed wetland hardwoods on site contain a diversity of bugs, crawfish, mayflies, damsel flies, midges, and snails. Some of these are important food sources for higher organisms. The apple snail, for example, is an important food source for such birds as the limpkin and the endangered snail kite, and its eggs are food for crawfish and other organisms. The biological communities that exist in the wetlands and uplands at the site are determined by a number of factors, including the depth and duration of the hydroperiod, soils, climate, temperature, and availability of sunlight. These communities and their habitats will react to changes in light, water, temperature, and many other subtle effects, causing changes in plant diversity and structure, the areal extent of certain types of habitats and wetlands, and utilization by wildlife. Natural fluctuations in the hydroperiod also cause these changes, generally from the exterior edges of a wetland to the interior. The wetlands in the BCWMA have been able to withstand the natural drought and flood periods, or they wouldn't be there today. Periodic burning is essential to the health of ecosystems such as in the Bull Creek area. Fires reduce the prevalence of species less tolerant to fire, allow other species to strengthen their presence, return organic material to the soil, and reduce the fuel available for wild fires. Originally occurring naturally as a result of lightening strikes, prescribed burns are now undertaken by agencies such as the Division of Forestry and the Game and Fresh Water Fish Commission to replicate the beneficial functions of natural periodic burning. Fire management is used as a land management technique at BCWMA and continued fire management at the BCWMA will maintain a natural ecological setting typical of Florida. Slight variations in elevation which mark the difference between wetlands and uplands can result in utilization of the areas by different animal communities. Where different types of plant communities meet, an "ecotone" is created. Where an ecotone exists, the "edge effect" of the competition between the two communities occurs. The result of the edge effect is higher plant and animal species diversity, which is extremely important to the natural community. Some animals make specific use of the ecotone for habitat and food resources. Many amphibians, frogs in particular, live in the ecotone. Some birds will not roost in the upland forests but will roost in the edge of the forest adjacent to wetlands. Wetlands in the BCWMA are connected to the remainder of the Bull Creek system through groundwater resources. Their biological and ecological communities are also connected as the same organisms move throughout the system. Isolated wetlands also exhibit a "moving edge" effect, where changes in the surface water and water table levels cause different plants, or plants at different levels of maturity, to exist in the wetland and its perimeter. This increases the productivity of the wetland by making it attractive to a wider variety of plant and animal species. If the expansion and contraction of isolated wetlands is reduced by lowered water levels, the smaller wetlands would exhibit a reduced edge effect, and the cumulative effect of this reduction over time would disrupt the functioning of the wetland-upland system. Isolated wetland systems are more sensitive to drawdowns in the surficial aquifer than connected wetland systems because the drainage area contributing water to the wetland system is smaller. Isolated herbaceous wetland communities are the most sensitive of the vegetative communities on BCWMA to drawdowns in the surficial aquifer. The surficial aquifer fluctuates naturally as much as five feet annually. Rainfall is the primary source of water for the surficial aquifer. Water levels in the surficial aquifer respond very quickly to rainfall events. Hydroperiods of the wetland systems in the BCWMA respond to rainfall and surficial aquifer levels. The wetland hydroperiods vary from year to year, and wetland ecosystems have adopted to those annual changes. But a groundwater withdrawal from the surficial aquifer in the Bull Creek area would cause a corresponding lowering of the surface water level, since the wetlands are not "perched", or separated from the aquifer by a confining layer. A drawdown would lower water levels throughout the hydroperiod, under both high water and low water conditions, with a more pronounced effect during the dry season and drought periods. Some of the over twenty threatened and endangered plant species present at Bull Creek grow in shallow, marginally wet areas. Changes in even a few inches of groundwater would cause these plant species to be retarded in growth, and their abundance would decrease or they would die out at the site. Many of the wetlands are shallow, broad, sloping areas, and groundwater elevation changes of just a few inches will cause changes in the areal extent of these wetlands. Even the .14 foot drawdown predicted by SBWA's modeling would affect shallow inundated or saturated systems by changing the moisture level at the surface, particularly by affecting the lowest water levels. Changes in the vegetative composition of wetlands will affect the macro-invertebrate characteristics of a site. For example, as water levels change, the density of the vegetation (in terms of number of plant stems per acre) can decrease, leaving fewer places for the macro-invertebrates to hide, and the populations of macro-invertebrates will decrease through predation. As food sources, habitat and breeding grounds decrease, those animal species that can relocate will attempt to do so. Relocation can adversely affect the survival of the species; for example, a wood stork unable to find a particular food upon which it is dependent at a particular interval in its life cycle may abandon its nest and its young. Animals that attempt to relocate may find that there is not a suitable similar habitat available, making their attempt to adjust to the change in their environment unsuccessful. The proposed use will not significantly affect the stages or vegetation of the upland communities at the BCWMA because they are not as dependent on saturation or inundation as a wetland community. Forested wetland systems, be they isolated or connected, will not be influenced by a drawdown of the magnitude predicted by SBWA for the surficial aquifer. Forested systems have deep root zones and the canopy provides shading to the strata below. Forested systems are able to tolerate natural changes in hydrology. The SBWA assessment does not offer any detailed cataloguing of the plant and animal communities on site, or a description of how the systems operate or interface with each other. It does not provide sufficient information to be able to assess the impacts of the proposed wellfield on these systems. There was insufficient information presented by the applicant to conclude that the environmental harm to be caused by operation of a wellfield at the BCWMA has been reduced to an acceptable level. The applicant relied on the fact that drawdowns in the surficial aquifer will be minimal, without fully considering the impact of those minimal drawdowns on a fragile wetland ecosystem during a dry period. Water Demand The SBWA was created by special act in 1983 as a dependent special district for the purpose of developing regional water supplies and transmission of water to water distribution systems. In its existence so far, its labors have been in the former, and none in the latter category. Efforts to develop a regional water supply have been frustrated by litigation, by reluctance of local public systems to give up their authority and by delays in pursuing and processing CUP applications, two of which are still pending, in addition to the instant application. The City of Melbourne's public water system provides water to Melbourne, Palm Bay and West Melbourne, and to some unincorporated areas surrounding Melbourne. It also supplies water to the area called south beaches, comprised of the Brevard County area south of Patrick Air Force Base, including Satellite Beach, Melbourne Beach, Indiatlantic and Indian Harbor Beach. The current water supply is Lake Washington, which is part of the chain of lakes on the St. Johns River. The city of Melbourne was granted a CUP on January 15, 1991, for withdrawals from Lake Washington, ranging from 27.15 million gallons maximum daily withdrawals in 1991 to 21.7 million gallons maximum daily withdrawals in 1998. In addition, Melbourne has planned a new facility and has the CUP to withdraw 8.13 million gallons a day from the Floridan Aquifer commencing in 1993. After reverse osmosis treatment, the groundwater withdrawal will yield 6.5 million gallons a day finished water, making up the difference from reduced withdrawals from Lake Washington. Approximately 56 potable water systems have been identified by SBWA in South Brevard, south of the Pineda Causeway. Almost all are small private systems. Besides Melbourne, the other major water supplier in the area is General Development Utilities (GDU), serving the City of Palm Bay. GDU's CUP expires in 1993 with an average daily withdrawal of 6.5 mgd and maximum daily withdrawal of 8.5 mgd. It has ample capacity until 1996, and beyond to the year 2000, if an additional Department of Environmental Regulation capacity rating is obtained. The total capacity of the two major existing facilities is approximately 30 mgd and total existing consumptive use quantities (including existing CUPs with expiration dates varying from 1993 to 1998) approach 40 mgd. The current SBWA water master plan assumes that existing sources need replacing. More specifically, SBWA, if this CUP is granted, seeks to replace Lake Washington as the primary source of water in the area with the groundwater obtained from the BCWMA wellfield. An agreement between the City of Melbourne and SBWA provides that the City will initially purchase 8 mgd, plus all future needs of water from the SBWA. This 8 mgd would be used by Melbourne prior to using its 6.5 mgd finished water from the RO facility, and the RO water would be used prior to withdrawals from Lake Washington. The agreement, dated January 9, 1991, acknowledges the need for, and specifically authorizes improvements to Melbourne's Lake Washington Water Treatment Plant, including the conversion of the existing high service pumping station to a low service pumping station with average daily capacity of 20 mgd and maximum capacity of 25 mgd. (SBWA Ex. 49) GDU is a private utility and currently is outside the jurisdiction of the SBWA. General Development Corporation is in receivership and the City of Palm Bay is negotiating for purchase of the utility. If the purchase is successful, the supply will become publicly owned and subject to the jurisdiction of the SBWA. The City of Palm Bay is not bound to purchase GDU at any price, and the requirement that it would shut down its newly purchased facility to receive water from SBWA is a disincentive to the acquisition. In the meantime, GDU has no incentive to reduce CUP capacity and devalue its facility. GDU's service has been uninterrupted and reliable. Contamination to the surface aquifer utilized by GDU has been successfully treated. Although septic tanks proliferate in Palm Bay, their location, as well as the presence of confining layers in the surficial aquifer, reduce the susceptibility of GDU wells to contamination from septic tanks. The applicant's concerns about unreliability and safety of Lake Washington as a continued water source are unsubstantiated by the weight of evidence in this proceeding. Surface water facilities have been used in Florida since before the turn of the century and no major facility has ever been off-line one day due to raw water contamination. Nor has any major Florida surface water plant ever been sabotaged. There is a greater chance in Florida of problems with pipeline failures, and the miles of pipes planned to transmit ground water from Bull Creek east to SBWA consumers increase the chances of those problems. Recently, the SJRWMD Upper Basin Project has significantly improved the water quality and quantity in Lake Washington through restoration of marshlands in the upper basin and capping flowing wells. Restored marsh areas will allow for additional removal of nutrients and provide an additional storage to the Lake Washington/Upper Basin system, significantly improving safe yield quantities. Comparisons of concentrations of raw water chlorides and total dissolved solids for the drought years of 1989 and 1990, show significant reductions for the latter time frame. Recent evaluations indicate that Lake Washington would be acceptable in terms of chlorides and TDS concentrations for a 35 mgd withdrawal, even during 50 and 100 year droughts. Water quality improvements to Lake Washington can be directly related to the Upper Basin project. Trihalomethanes are regulated by the Safe Drinking Water Act. They are produced by the disinfection process of treating raw water with chlorines, and they are carcinogenic. A previously experienced problem at the Melbourne plant has been corrected with operational changes. As recently as 1988, an internal staff report by SJRWMD staff provided: Lake Washington has been a reliable source of public water supply since 1960 and can remain so in the future with the continuation of sound basin planning and watershed management by the St. John's river Water Management District. The quality of the raw water from Lake Washington is subject to annual and seasonal variations that make the treatment process more difficult, and the quality of the delivered water less consistent, than would be the case with a groundwater supply. A supplemental water source near Lake Washington would improve the quality of the water delivered to the users, would increase the total volume that could be taken from the lake in times of stress, and would provide a reliable alternative in case of emergency. The upper zone of the Floridan Aquifer within south Brevard County has the potential to supply a significant portion of the area's future water needs with existing low-pressure, reverse osmosis technology at a cost that is comparable to current supplies.

The Issue The issues to be determined in this case are whether proposed Florida Administrative Code Rules 62-42.100, 62-42.200, 62-42.300, and a document incorporated by reference (“the Proposed Rules”) are invalid exercises of delegated legislative authority; whether the Department of Environmental Protection (“DEP”) complied with statutory requirements regarding preparation of a statement of estimated regulatory costs (“SERC”) for the Proposed Rules; and whether the approval by the Governing Board of the Suwannee River Water Management District (“SRWMD”) of a document entitled “Recovery Strategy: Lower Santa Fe River Basin” (“Recovery Strategy”) is invalid because it required rulemaking.
Findings Of Fact The Parties The Alliance is a Florida not-for-profit corporation with its principal place of business at 203 Northeast First Street, Gainesville, Florida. Its mission is to ensure the restoration, preservation, and protection for future generations of the ecosystems along the Ichetucknee River, including its associated springs. The Alliance has approximately 40 members. Seventeen members appeared at the final hearing and testified that they regularly use the Ichetucknee River and its associated priority springs for recreation, wildlife observation, and other purposes. Seventeen members is a substantial number of the total membership of the Alliance. Petitioner Still is a natural person who owns 117 acres of land in Bradford County. He uses the land primarily for timber production. He does not have a consumptive (water) use permit. He has used the Lower Santa Fe River and associated springs for recreation since 1979 and continues to visit the river and springs for this purpose. Petitioner FWF is a Florida not-for-profit corporation with its principal place of business at 2545 Blairstone Drive, Tallahassee, Florida. The mission of FWF includes the preservation, management, and improvement of Florida’s water resources and wildlife habitat. In the parties’ Pre-Hearing Stipulation, FWF identified Manley Fuller, its President, as its witness for organizational standing. It also listed “standing witnesses as needed,” but did not name them. At his deposition, Mr. Fuller stated that he did not know how many FWF members use the MFL water bodies. At the beginning of the final hearing, FWF made an oral proffer that it was prepared to call “10 members who are using the water bodies.” Later, FWF stated that some members were unwilling or unable to come to Tallahassee, but suggested that 10 or 15 might (now) be talked into coming to the final hearing or testifying by video. FWF also proffered a membership list, showing the number of members by county. It shows that FWF has a total of 11,788 members. In the six counties in the vicinity of the MFL water bodies (Alachua, Bradford, Columbia, Gilchrist, Suwannee, and Union) there are 457 FWF members. Ten, 15, or 20 members is not a substantial number of FWF’s 11,788 total members, nor is it a substantial number of its 457 members who live in the vicinity of the MFL waterbodies. Respondent DEP is a state agency with powers and duties under chapter 373, Florida Statutes, including the power and duty under section 373.042(1), which it shares with the water management districts, to establish minimum flows for surface watercourses and minimum levels for groundwater (“MFLs”) and recovery strategies when MFLs will not be achieved. Respondent/Intervenor SRWMD is a regional water management district with powers and duties under chapter 373, including powers and duties related to MFLs. The MFL waterbodies are located within SRWMD. Intervenor SJRWMD is the water management district adjacent to SRWMD. A portion of SJRWMD is included within the planning area created for the MFL waterbodies. Intervenor NFUCG is a regional trade organization representing interests of public water supply utilities in North Florida that hold consumptive use permits and are subject to the Proposed Rules. Intervenors CCUA and JEA are two members of NFUCG. Intervenors Alachua County, Gilchrist County, Suwannee County, Bradford County, and Columbia County are political subdivisions of the State in geographic proximity to the MFL water bodies. These Counties have the duty to plan for and protect the MFL water bodies as part of their local government comprehensive planning responsibilities under chapter 163, Florida Statutes. Minimum Flows and Recovery Strategies The water management districts and the DEP are required to establish minimum flows for surface water courses. § 373.042(1), Fla. Stat. Minimum flows are “the limit at which further withdrawals would be significantly harmful to the water resources or ecology of the area.” § 373.042(1)(a), Fla. Stat. If the existing flow in a water body is below its established minimum flow, DEP or the district is required to develop a “recovery strategy” designed to “[a]chieve recovery to the established minimum flow or level as soon as practicable.” § 373.0421(2), Fla. Stat. MFLs and recovery strategies are required to be included in a water management district’s regional water supply plan. § 373.709(2)(c) and (g), Fla. Stat. Water management districts must develop regional water supply plans in regions where they determine existing sources of water are not adequate to supply water for all existing and future users and to sustain water resources and related natural systems. § 373.709(1), Fla. Stat. SRWMD does not have a regional water supply plan. It is working on a draft plan that is expected to be completed in late 2015. The MFL Water Bodies The Lower Santa Fe River runs for approximately 30 miles from Santa Fe River Rise Spring to its confluence with the Suwannee River. The Lower Santa Fe is fed primarily by groundwater discharge from the Upper Floridan aquifer including the baseflow provided by several major springs. The Lower Santa Fe River system, including its tributary, the Ichetucknee River (below State Road 27), is classified as an Outstanding Florida Water, a designation conferred on waters “with exceptional recreational or ecological significance.” See Fla. Admin. Code R. 62-302.700(3). The Ichetucknee River runs for six miles from the Head Spring to its confluence with the Lower Santa Fe. Its flow is derived almost entirely from springflow. The ecological, recreational, and economic values of the Santa Fe and Ichetucknee Rivers are widely recognized. Both rivers flow through lands preserved for public use as part of the State Park System. SRWMD published a Water Supply Assessment in 2010 to determine whether water demands could be met for the 2010-2030 planning period without adversely affecting natural resources. The North Florida Groundwater Flow Model was used to evaluate groundwater withdrawals and their effect on aquifer levels and the flows in springs and rivers. The 2010 assessment concluded that groundwater levels of the Upper Floridan Aquifer in the eastern and northeastern portions of the District were in decline. The District’s analysis of river and streamflows also found declining trends. It was concluded that existing water sources would not be able to meet projected water demands over the planning period. As a result, the Lower Santa Fe River Basin (including the Ichetucknee River) was designated as a water supply planning region and SRWMD began to develop minimum flows for these water bodies. Because groundwater withdrawals within the adjacent SJRWMD were also affecting the MFL waterbodies1/, DEP, SRWMD, and SJRWMD entered into an interagency agreement in 2011 to work together on water supply issues and the development of a joint regional groundwater model. Development of the Minimum Flows The procedural difficulties faced in establishing minimum flows affected by water uses in two water management districts eventually lead to the Legislature’s creation of section 373.042(4) in 2013, which authorizes DEP to adopt relevant rules which can be applied by the water management districts without the need for their own rulemaking. In June 2013, SRWMD requested that DEP adopt minimum flows for the MFL waterbodies pursuant to the new law. A gage2/ for the Lower Santa Fe River near Fort White, and a gage for the Ichetucknee River on US 27 were selected for establishment of the respective minimum flows. The minimum flows were determined by first establishing a hydrologic baseline condition at the two gages. Then, SRWMD determined a departure from the baseline that would cause significant harm to the water resources and ecology of the area. The minimum flows are expressed as stage duration curves rather than a single number, in order to account for the changes in flow that occur naturally due to seasonal, climatic, and other factors affecting rainfall. Once the minimum flows were determined, SRWMD evaluated whether they are being met. It concluded that the minimum flows are not being met. Therefore, in accordance with section 373.0421(2), a recovery strategy had to be prepared and implemented. The Recovery Strategy A recovery strategy is a plan for achieving a return to adopted MFLs and will generally include plans for developing new water supplies and implementing conservation and efficiency measures. See § 373.0421(2), Fla. Stat. The practice of the water management districts has been to also adopt regulatory measures that are used in the review of consumptive use permits as part of a recovery strategy. See, e.g., Fla. Admin. Code R. 40D-80.074. That practice was followed for the MFL water bodies. The Recovery Strategy includes planning, water conservation, water supply development, and water resource development components. These components comprise the non-regulatory portion of the Recovery Strategy. Section 6.0 of the Recovery Strategy, entitled “Supplemental Regulatory Measures,” is the regulatory portion and is incorporated by reference in proposed rule 62-42.300(1)(d). The Recovery Strategy is to be implemented in two phases and the objectives of each phase are described in Table 4-1 of the Recovery Strategy. Phase I includes adoption of supplemental regulatory measures, work with user groups to implement water conservation measures, completion of an improved regional groundwater model, and identification and investigation of water supply projects. In Phase II of the Recovery Strategy, DEP plans to use the new regional model to develop long-term regulatory measures to address regional impacts to the MFLs water bodies. In addition, SRWMD and SJRWMD would develop and implement additional water resource and supply projects. The Proposed Rules The Proposed Rules would create three sections in a new chapter 62-42 of the Florida Administrative Code. Rules 62- and 62-42.200 set forth the scope and definitions: 62-42.100 Scope The purpose of this chapter is to set forth Department-adopted minimum flows and levels (MFLS) and the regulatory provisions of any required recovery or prevention strategy as provided in Section 373.042(4), F.S. The Department recognizes that recovery and prevention strategies may contain both regulatory and non-regulatory provisions. The non-regulatory provisions are not included in this rule, and will be included in the applicable regional water supply plans approved by the appropriate districts pursuant to Section 373.0421(2) and Section 373.709, F.S. [Rulemaking authority and law implemented omitted.] 62-42.200 Definitions When used in this chapter, the following words shall have the indicated meanings unless the rule indicates otherwise: Flow Duration Curve means a plot of magnitude of flow versus percent of time the magnitude of flow is equaled or exceeded. Flow Duration Frequency means the percentage of time that a given flow is equaled or exceeded. [Rulemaking authority and law implemented omitted.] Rule 62-42.300 is where the proposed minimum flows are set forth. The minimum flows for the Lower Santa Fe River are established in rule 62-42.300(1)(a); the minimum flows for the Ichetucknee River are established in rule 62-42.300(1)(b); and the minimum flows for 16 priority springs are established in rule 62-42.300(1)(c). The minimum flows for the Santa Fe and Ichetucknee Rivers are expressed as water flow in cubic feet per second (“cfs”) at various points on a flow duration curve. The minimum flows for ten named springs associated with the Santa Fe River and six named springs associated with the Ichetucknee River are set forth as a “percent reduction from the median baseline flow contribution of the spring to the flow” at a particular river gage. This approach, which ties spring flow to river flow, was used by DEP because there is minimal flow data for the springs. Rule 62-42.300(1)(d) adopts by reference “Supplemental Regulatory Measures,” which is Section 6.0 of the Recovery Strategy. Rule 62-42.300(1)(e) states that DEP, in coordination with SRWMD and SJRWMD, shall reevaluate these minimum flows after completion of the North Florida Southeast Georgia Regional Groundwater Flow Model, which is currently under development. The rule also states that DEP will “strike” rules 62-42.300(1)(a) through (d) and adopt new rules no later than three years after completion of the final peer review report regarding the new groundwater model, or by December 31, 2019, whichever date is earlier. The Supplemental Regulatory Measures adopted by reference in rule 62-42.300(1)(d) are intended to provide additional criteria for review of consumptive use permit applications during Phase I. These measures would be applied to water uses within the North Florida Regional Water Supply Planning Area. For the purposes of the issues raised in these consolidated cases, it is necessary to discuss three categories of permit applications and how they would be treated under the Supplemental Regulatory Measures in Phase I: (1) A new permit application that shows a “potential impact” to the MFL water bodies must eliminate or offset the potential impact; (2) An application to renew a permit, which does not seek to increase the amount of water used, would be renewed for five years no matter what impact it is having on the MFL water bodies; however, if the impact is eliminated or offset, the renewal would not be limited to five years; and (3) An application to renew a permit which seeks an increased quantity of water would have to eliminate or offset the potential impact to the MFL water bodies associated only with the increase. This category of permits is limited to a five-year renewal unless the existing impacts are also eliminated or offset. See § 6.5(a)-(d) of the Recovery Strategy. Section 6.5(e) states that existing permits that do not expire during Phase I are considered consistent with the Recovery Strategy and are not subject to modification during the term of their permits. Many permits are issued for a 20-year period, so Phase I would not capture all existing permits because they would not all expire during Phase I.3/ DEP stated that existing permits may be affected by the regulatory measures DEP plans to adopt for Phase II. Section 6.5(f) of the Supplemental Regulatory Measures states that permittees are not responsible for impacts to the MFL water bodies caused by water users in Georgia, or for more than the permittee’s “proportionate share of impacts.” The record evidence established that the effect of Georgia water users on the MFL water bodies is small. Section 6.6(b) requires permits for agricultural use in the counties surrounding the MFL water bodies to include a condition requiring participation in the Mobile Irrigation Lab (MIL) program. The purpose of SRWMD’s MIL program is to improve the efficiency of irrigation systems. SRWMD provides cost- sharing in this program. Whether DEP Must Adopt the Entire Recovery Strategy by Rule Petitioners contend that proposed rules 62-42.100(1) and (2) enlarge, modify, or contravene sections 373.042(4) and 373.0421(2) because these statutes require DEP to adopt all of a recovery strategy by rule, not just the regulatory portion of a recovery strategy. Respondents contend that it was consistent with the law for DEP to adopt only the regulatory portion of the Recovery Strategy by rule and have SRWMD approve the non- regulatory portion and implement it through a regional water supply plan. It has been the practice of the water management districts to adopt by rule only the regulatory portion of a recovery strategy and to implement the non-regulatory portion as a component of their regional water supply plans. This is primarily a legal issue and is addressed in the Conclusions of Law where it is concluded that DEP is not required to adopt the entire Recovery Strategy by rule. Whether SRWMD Must Adopt the Recovery Strategy By Rule Petitioner Still challenged SRWMD’s approval of the Recovery Strategy as violating the rulemaking requirements of section 120.54. However, Petitioner Still presented no evidence in support of his claim that the Recovery Strategy contains statements that meet the definition of a rule, but were not adopted as rules. Whether the Non-Regulatory Portion of the Recovery Strategy Will Prevent Recovery The Alliance claims that there are flaws in the non- regulatory portion of the Recovery Strategy that was approved by SRWMD, primarily related to the estimate of flow deficits in the MFL water bodies and the corresponding amount of water that must be returned to the system to achieve the minimum flows. There is unrefuted record evidence indicating that SRWMD did not account for consumptive use permits issued in the last three or four years. Therefore, the Recovery Strategy probably underestimates the flow deficits in the Lower Santa Fe and Ichetucknee Rivers and the amount of water needed to achieve the minimum flows.4/ However, as explained in the Conclusions of Law, the Alliance cannot challenge the non-regulatory portion of the Recovery Strategy in this proceeding. The Recovery Strategy, including the non-regulatory portion approved by SRWMD, is in Phase I. SRWMD can revise the Recovery Strategy at any time, and in Phase II can do so with the improved analysis made possible with the new regional model. As explained in the Conclusions of Law, the non-regulatory portion does not have to achieve recovery in Phase I. Whether the Minimum Flows are Based on the Best Information Available Petitioner Still contends that the minimum flows are not based on the best information available as required by section 373.042(1)(b). He claims that the wrong method was used to estimate streamflow, the modeling was based on a false assumption about the relationship between groundwater levels and river flows, the relationship between withdrawals and flows was not properly accounted for, withdrawals and other anthropogenic impacts were not properly distinguished, tailwater effects were not properly accounted for, and the wrong period of record was used. Petitioner Still’s arguments in this respect are based largely on his own opinions about the quality and significance of the technical data that was used and how it affects the modeling results used in establishing the minimum flows. Petitioner Still does not have the requisite expertise to express these opinions and he did not get expert witnesses at the final hearing to agree with his claims. Petitioner Still does not have an expertise in modeling to express an opinion about the ability of the model to use particular data or how the model accounts for various surface and groundwater phenomena. Petitioner Still failed to prove that the minimum flows are not based on the best available information. Whether the Proposed Rules Are Vague Petitioner Still contends the Proposed Rules are invalid because they use terms that are vague. Some of the terms which Petitioner Still objects to are the same or similar to terms commonly used in other environmental regulations, such as “best available information,” “impact,” “offset,” and “eliminate.” The term “potential impact” is not materially different than the term “impact.” The term “best available modeling tools” is not vague. It reflects the recognition that, like best available information, hydrologic models and technical information are continually being created and updated. Petitioner Still contends that the definitions of “Flow Duration Curve” and “Flow Duration Frequency” in proposed rules 62-42.200(1) and (2), respectively, are vague because they do not state whether “synthetic” data may be used in the production of the flow duration curve, or that they are based on a specific period of record. Synthetic data are numeric inputs used to account for missing data and are created by extrapolating from existing data. As an example, they can be used to satisfy a model’s need to have a water flow entry for every month in a multi-year period being analyzed when there is no actual data available for some of the months. The use of synthetic data is a regular and accepted practice in modeling and does not have to be mentioned in the rule. Flow duration curves and flow duration frequencies are calculated from data covering specific periods of record. Although the definitions of these two terms in proposed rule 62-42.200 could contain more information than is provided, the proposed definitions are not inaccurate. They are not vague. Petitioner Still contends that proposed rule 62-42.300(1)(a) is vague because it establishes the minimum flows for the Santa Fe River at a location without precisely identifying the location. The record shows that the reference in proposed rule 62-42.300(1)(a) to “the Santa Fe River near Ft. White, FL” is the actual name of the United States Geological Survey flow gage that has been in use for many years. Furthermore, proposed rule 62-42.300(1)(c), which establishes the minimum flows for the priority springs, refers to “the respective river gages listed in paragraphs 62-42.300(1)(a) and (b).” Therefore, it is made clear that the reference to “the Santa Fe River near Ft. White, FL” in proposed rule 62-42.300(1)(a) is a reference to a river gage. The rule is not vague. Petitioner Still asserts that the minimum flows in proposed 62-42.300(1) are vague because they do not identify the period of record that was used in deriving the flow duration curves which are used in the rule. He compared the wording in the proposed rule to SRWMD’s existing rule 40B-8.061(1), which identifies the technical report from which the flow duration curve in that rule was derived. A general description of flow duration curves is found in “Minimum Flows and Levels for the Lower Santa Fe and Ichetucknee River and Priority Springs” dated November 22, 2013 (“MFL Technical Document”), at page 3-6: They show the percent of time specified discharges were equaled or exceeded for a continuous record in a given period. For example, during the period 1932 to 2010, the daily mean flow of the Santa Fe River near Fort White (Figure 3-2) was at least 767 cfs, 90 percent of the time. The curves are influenced by the period of record used in their creation, but for comparison purposes between different scenarios over a fixed time period they are extremely useful. [Emphasis added.] However, proposed rule 62-42.300(1) does not give the period of record for the flow duration curves that will be used to determine compliance with the minimum flows for the Lower Santa Fe and Ichetucknee Rivers. Respondents argued that identifying the period of record is unnecessary because anyone interested in knowing the period of record or anything else pertaining to how the flow duration curves were produced could refer to the MFL Technical Document. This is not a situation where a specific number and unit, such as 100 cfs, has been established as a criterion based on technical analyses that can be found in documents. In such a case, the technical documents are not needed to determine compliance with the criterion; they simply explain why the criterion was selected. In the case of a flow duration curve, however, the period of record for the data to be used must be known to determine compliance. For example, proposed rule 62-42.300(1)(a)1. would establish the following criterion: “3,101 cubic feet per second (cfs) for a flow duration frequency of five percent.” Five percent of what? Five percent of what data set? Data from what time period? Must the same synthetic data be used? The rule does not inform persons subject to the rule what data SRWMD will use to determine compliance. They would not know how to calculate flow duration frequencies without reviewing the MFL Technical Document. Because the minimum flows are not completely identified in the rule, they are vague. Whether a Minimum Flow Should be Established for Each Priority Spring Petitioner Still contends that the Proposed Rules are invalid because minimum flows are not established for each priority spring, which causes them to be unprotected. He claims that each spring needs its own minimum flow “that takes into account the surface and ground water inputs to its flow.” DEP and SRWMD presented evidence that establishing minimum flows for each spring was impracticable because there were insufficient data for the springs. Petitioner Still did not refute this evidence. Whether the Proposed Rules Allow Further Degradation of the MFL Water Bodies The Alliance contends that the Proposed Rules must reduce permitted withdrawals in Phase I and must require monitoring of water use by agricultural water users, but it did not present evidence that these alternative regulatory measures are practicable in SRWMD in Phase I. The Alliance did not show there are permitting mechanisms that have been used by other water management districts as part of the first phase of a recovery strategy that are practicable for use in SRWMD and would be more effective. The only evidence presented on the subject of what regulatory measures other water management districts have adopted as part of a recovery strategy pertained to the Southwest Florida Water Management District (“SWFWMD”). That evidence showed that SWFWMD took a similar approach of allowing existing permitted uses to continue their water withdrawals while new water supplies and conservation mechanisms were developed. The Alliance contends that the Supplemental Regulatory Measures do not prevent further degradation because there are projected to be numerous, new agricultural water uses in Phase I. However, under section 6.5(b), new water uses will not be allowed to adversely impact the MFL water bodies. The Alliance makes a similar argument regarding existing agricultural water users who will request an increase in water. Under section 6.5(c), increases in water use will not be allowed to adversely impact the MFL water bodies. Whether the SERC and Revised SERC are Good Faith Estimates and Whether the Proposed Rules Impose the Lowest Cost Regulatory Alternatives Petitioner Still failed to meet his burden under section 120.56(2) of going forward with evidence to support his allegations that DEP’s original SERC or the revised SERC were not good faith estimates of regulatory costs associated with the Proposed Rules. The record evidence shows they are good faith estimates. He also failed to meet his burden under section 120.56(2) of going forward with evidence to support his allegations that the objectives of the law being implemented could be substantially accomplished by a less costly regulatory alternative.
