Findings Of Fact The Petitioner is a special tax district created by special act of the Florida Legislature. Chapter 71-822, Laws of Florida. The district covers approximately seventy-two square miles in northern Palm Beach County and southern Martin County, Florida. Petitioner's purpose is to provide water, sewer, drainage and solid waste services within the district. In conformity with its powers, the Petitioner operates an advanced waste water treatment plant on property which it owns in northern Palm Beach County. Petitioner has secured appropriate permits from DER in order to construct and operate the treatment plant. The treatment plant is among the most advanced in southeastern Florida. It has a four million gallon daily capacity, which could be increased to an eight million gallon capacity. In treating waste water the plant utilizes filtration, disinfection, retention in a holding pond, and discharge into a remote off-site area. The present discharge system is to pump effluent from the retaining pond through a canal or drainage system to a recharge or discharge lake which is located approximately three miles north and west of the treatment plant. This is known as the western discharge system, and was installed at a cost of approximately one million dollars. Due to the large amounts of pumping activity, it is an expensive system to utilize. Through its instant application, the Petitioner is seeking a permit allowing it to discharge effluent on-site. Effluent would flow into percolation ponds that have already been constructed. Effluent would settle in the ponds, and eventually would percolate through the soil. This system would he less expensive to operate than the western discharge system. Petitioner is interested in experimenting with the amount of waste water treatment that can be obtained through action of vegetation in the percolation ponds upon the effluent. Such a natural system, if it operated effectively, could save the Petitioner additional money in treating waste water by reducing the need for chemical treatment. Petitioner's waste water treatment presently results in a discharge of effluent which within some parameters meets even drinking water standards. The Petitioner's system very effectively treats bio-chemical oxygen demand ("bod"), suspended solids, nitrogen, and phosphorus in the effluent. Reports have been submitted by the Petitioner to DER which indicate that the system does not meet DER's standards for advanced waste water treatment. Samples upon which these reports were based were taken at a point in the system before the effluent was subjected to the action of the retention pond and the subsequent bumping into the western discharge system. Samples taken beyond the retention pond indicate that DER's standards are met for "bed", suspended solids, total nitrogen, and total phosphorus. The Intervenor owns property adjacent to the Petitioner's waste water treatment plant. The Intervenor operates a well field and drinking water treatment plant on the property, and provides drinking water to residents of the Town of Jupiter and surrounding communities from the well field. The Intervenor acquired its treatment plant, and surrounding well fields from a private utility company. The Petitioner was aware of the well field when it purchased the property upon which it presently operates its waste water treatment plant. While the Petitioner's plant adequately treats waste water in terms of "bod", suspended solids, total nitrogen, and total phosphorus it does not treat the waste water for heavy metals, pesticides, or viruses. These are common elements found in waste water effluent in the south Florida area. The Petitioner's proposal is to discharge its effluent into on-site ponds. The effluent would then percolate into the ground. The retention ponds are located at a distance from 1200 to 1600 feet from the nearest of the Intervenor's wells. Water which percolates from these ponds would flow directly toward the wells, and would eventually find its way into the wells. The flow from the retention ponds to the wells would be increased due to the draw-down effect that the wells have on the surrounding water table. As water is drawn from the wells, the adjoining water table becomes depressed in the area of the wells, and water from the surrounding area flows more rapidly into the area of the wells. Heavy metals will not be filtered out as a result of retention or percolation. Heavy metals in the effluent would eventually find their way into the Intervenor's well fields. Estimates as to the amount of time that it would take for water from the percolation ponds to reach the wells varied from four months to six years. The longer estimate appears the more reasonable; however, the evidence is conclusive that eventually waters from the percolation ponds would reach the wells, and that heavy metals in the water would not be filtered out. The Petitioner proposes to obviate any problems with heavy metals reaching the well fields by operating testing wells between the percolation ponds and the well fields. If any heavy metals were detected in the ground water, Petitioner would again use the western discharge system rather than the percolation ponds. While this would prevent increased contamination of the wells, contamination that had already reached the test wells would reach the Intervenor's wells. It was suggested that the percolation ponds could be drawn down in order to reverse the flow of ground water back into the percolation ponds, thence to be pumped through the western discharge system. In order to accomplish this, however, the percolation ponds would have to be more than forty feet deep, which they are not. The effect of heavy metals intruding into the Intervenor's water supply could be to increase the cost of treatment, or to render the wells unfit for use. Uncontaminated drinking water supplies are rare in the northern Palm Beach County area, and the expense of finding a new water supply is difficult to calculate.
The Issue Whether Gar-Con's revised application for a permit to construct a sewage plant, and soakage trenches to dispose of the effluent, should be granted?
Findings Of Fact Eight to ten miles south of Melbourne Beach and 8.3 miles north of Sebastian Inlet, Gar-Con plans to develop a parcel of land stretching west from the Atlantic Ocean, across Highway A1A, to the Indian River. Gar-Con expects to build a motel and residential complex complete with tennis courts, parking garage, water treatment plant and the sewage treatment facility for which a construction permit is sought in these proceedings. The sewage treatment plant would be built on a site 480 feet west of Highway A1A and 90 feet south of Gar-Con's northern property line, at an elevation of 11 or 12 feet above mean sea level. Ocean Way Water and Sewer Association, Inc. is to be organized as a nonprofit corporation to own and operate the wastewater treatment facility. The Public Service Commission, through the director of its water and sewer treatment, has taken the position that the proposed "sewer system will fall within the exemption described in Section 367.022(7), Florida Statutes." DER's Composite Exhibit A. PACKAGE PLANT PROPOSED The facility Gar-Con proposes is designed to treat 100,000 gallons of sewage daily, which is the estimated "total flow" (T. 75) the sanitary engineer who designed the system anticipates from the development. Sewage generated by the development would flow to the plant, through a bar rack designed to remove rags and other large objects, and into aeration tanks where, over a 24 hour period, interaction with air and a biological mass would supply oxygen and cause the formation of biological floccules. The flocculant sewage would then move to a clarifier hopper. During its five hour stay there, solids which were not earlier segregated as the sewage moved over a weir into the clarifier, would be precipitated and removed. The clear, residual liquid would be pumped through one of two sand filters (each of which would also have granular activated carbon and be capable of filtering 100,000 gallons daily) into one of two chlorine contact chambers where a gas chlorinator would introduce chlorine for an hour. Under ordinary circumstances, the chlorinated effluent would then be pumped into one of two soakage trenches. The soakage trenches, each designed for use every other week, are to be gravel-filled ditches covered over first with felt paper, then with compacted fill. The gravel would lie at least one foot beneath the surface of the ground in a space ten feet wide and three feet deep stretching the 940 foot length of each soakage trench. Punctured like sieves, two six-inch PVC pipes would run through the gravel, sweating effluent from their pores. There is also a plan to dig a percolation pond or grassed swale five feet deep, 120 feet long and 80 feet wide near the wastewater treatment plant, which could serve as a receptacle for effluent, in case of "a 1:10 year storm or when the filters are down and/or if soakage trenches would need repair." Gar- Con's Exhibit 2-A. It would hold about 100,000 gallons. The solids caught by the weir, those extracted in the clarifying process, and those recovered from backwashing the filters would serve as catalyst for the aeration process as needed. Excess sludge, about 3,000 pounds monthly, would undergo "aerobic digestion," before being removed to Brevard County's Central Disposal Facility on Adamson Road, for disposal there. Gar- Con's Exhibit No. 7. Primary and secondary drinking water standards would be met by the effluent as it left the plant (although the engineer who designed the system would not drink the effluent himself), except that, from time to time, nitrate concentrations might reach 12 milligrams per liter, and except in the "event that a homeowner might put some type of [inorganic toxic or carcinogenic] material into the sewer system." (T. 86) The biological oxygen demand (BOD) would be ten milligrams per liter; suspended solids would probably amount to about five milligrams per liter; pH would probably be slightly under seven; nitrates would average approximately eight milligrams per liter but would "peak out at certain times during the year, for maybe extended periods up to two months, at twelve milligrams per liter," (T. 80); and there would be a chlorine residual after 60 minutes of two milligrams per liter. AMBIENT WATERS There would be no direct discharge to the Atlantic Ocean, Indian River or any other body of surface water, nor would any indirect effect on surface waters be measurable. No body of surface water lies within 500 feet of the site proposed for the plant and soakage trenches. Potable groundwater underlies the site; the groundwater table slopes toward the Atlantic Ocean, 9.5 to 12.5 feet below ground. "[D]uring the traditional rainy season," Gar-Con's Exhibit 2B, Attachment, p.3, the groundwater may rise to within seven feet of the surface. The PVC pipes in the soakage trenches are to be placed two and a half feet deep. As effluent percolated through the sandy soil, there would be "mounding" of the groundwater underneath the soakage trenches, and dispersal in all directions. Surface flow is to be diverted from the soakace trenches so that only rainwater falling directly on them would percolate down through the gravel beds. Taking soil characteristics into account, and assuming a "water table depth" of 20 feet, an engineer retained by Gar-Con predicted that "the maximum expected groundwater rises beneath the east and west trenches are 2.4 and 2.1 feet, respectively under a loading of 100,000 gpd for a period of 7 days." Gar-Con's Exhibit No. 3. The water table depth, "the height, the top of the groundwater from the first restrictive layer," (T. 172), is probably more like 40 feet than 20, which accounts in part for the "conservatism" of the mounding predictions. Under very severe weather conditions (a 100 year storm), groundwater would rise as high as the bottom of the trenches making them unavailable to receive effluent, but the effluent would not be forced above ground. In a 100 year flood, water would be expected to rise to seven feet above mean sea level. Under such conditions, people could be expected to evacuate the area. In a 25 year storm, the system could be expected to continue to function. Groundwater to the north and east of the proposed site was sampled, and the samples were analyzed. The water to the north had 380 milligrams of chlorides per liter and the water to the east had 450 milligrams of chlorides per liter. As it left the proposed treatment plant, the effluent would contain approximately 150 milligrams of chlorides per liter. SOUND AND LIGHT Lights like those used as street lights are to be installed at four places in the wastewater treatment plant. A timer, which can be overridden, would turn the lights on at dusk and off at eleven o'clock at night. The lights would illuminate the plant adequately. Pumps would move sewage to and through the proposed plant. Most of the pump motors would be submerged and unable to be heard. Two electric blowers, a flow meter and a totalizer would also have electrical motors. The blowers and the blower motors are to be equipped with insulated fiberglass covers and the blowers would also have intake and double outlet silencers. Four feet from the plant the noise of the motors would be comparable to that of a home air conditioning unit. At the nearest residence the noise level would scarcely exceed background noise. At hearing, Gar-Con revised its application and agreed to install an emergency generator which would also be encased in insulated housing and is to be equipped with a muffler. AEROSOL AND ODOR Unless the proposed plant loses electric power for 24 hours or longer, no offensive odors would emanate from it. The bar rack and weirs would be regularly hosed down. Against the possibility of a power failure, Gar-Con agreed at hearing to install permanently an emergency generator with sufficient capacity to keep both the wastewater treatment plant and the water treatment plant it plans to build operable. No aerosol drift is foreseen. The surface of the liquid In the aeration tanks would be 1.4 feet below the top of the rim. Walkways four feet wide along the inside perimeters of the aeration holding tanks would prevent dispersal of most of aerosol. A decorative hedge around the treatment plant, which would eventually be 15 feet high, is a final fail-safe. WELLS To the north are two shallow wells within 500 feet of the site proposed for the wastewater treatment plant. Both wells belong to Kel Fox, who wrote Gar-Con that he had no objection to their proposed wastewater treatment facility in light of Gar-Con's agreement to furnish drinking water to existing facilities on his property and reimburse him expenses incurred in disconnecting the two shallow wells. Gar-Con's Exhibit 2E. There is a deep well within 500 feet to the south. DER and Gar-Con have entered into the following stipulation, dated September 2, 1983: Existing Wells. Prior to the operation of its waste water treatment plant, Gar-Con will offer to supply drinking water at a reasonable cost to owners of property on which are located operational or approved shallow drinking water wells that are within 500 feet of Gar-Con's land application site. Gar-Con will make this offer to all such owners known to it prior to the operation of its plant. Gar-Con will further offer to provide reasonable compensation to such owners to disconnect their shallow wells. Gar-Con will endeavor to arrange for provision of drinking water to these owners and the disconnection of those wells prior to the operation of its plant. Future Wells. Should nearby individual (non-corporate) property owners propose to construct shallow drinking wells located within 500 feet of Gar-Con's land application site after Gar-Con begins operation of its waste water treatment plant, Gar-Con also will offer to supply them with drinking water at a reasonable cost and to provide reasonable compensation to them to disconnect those wells. However, Gar-Con shall have no obligation to make any such offer to owners of future wells if sampling of monitoring wells located at or near its external property line indicates that the groundwater meets the primary drinking water standards and, after July 1, 1985, the secondary drinking water standards listed in Florida Administrative Code Rule 17-22.104. Gar-Con agrees to record a master notice of restriction barring future owners of lots within the Ocean Way development, which are owned by Car-Con at the time of permit issuance, from installing shallow drinking water wells on such property or otherwise using the shallow aquifer beneath their property as a source for irrigation or for potable water, so long as use of the proposed sewage disposal system continues, and the Department has not found that this restriction is unnecessary. This restriction, which shall be a covenant running with the land, further shall require future owners to purchase water from Gar-Con or any successor owner of the development's water system if Gar-Con or the successor provides water service. These restrictions also shall be contained in all other appropriate documents of title. In addition, Gar-Con plans to create a non-profit water and sewer association to own and control the development's water and sewer system. Gar-Con will include in the Articles of Incorporation of this association a requirement that all property owners served by the system must be members of the Association. Gar-Con is entitled to a zone of discharge extending to its current property line with the exception that the zone of discharge shall not include the area contained within a 100' radius of Gar-Cons's proposed water supply wells. DER Staff concurs that the above conditions, in conjunction with the sewage treatment and disposal system and the groundwater monitoring program proposed by the applicant, to meet the requirements of Chapter 17-4, F.A.C. will provide reasonable assurance that existing and future off-site and on-site property owners will be protected from any adverse effects that might result from the operation of the proposed sewage treatment disposal system. Petitioner's Exhibit No. 10. There are to be a half dozen monitoring wells to allow sampling of the groundwater at strategic points in the shallow aquifer. NATURAL RESOURCES Turtles nest in the general vicinity but off the site of the proposed project. Construction and operation of the proposed waste water treatment facility would have no impact on the turtles apart from making it possible for more people to live closer to where they nest.
The Issue The issue in this case is whether Respondent KW Resort Utilities Corp. ("KWRU") is entitled to issuance, by Respondent Department of Environmental Protection ("DEP"), of Domestic Wastewater Facility Permit FLA014951-012-DWIP and UIC Permits 18490-020 and 18490-021 (collectively, the "Permit at Issue"), authorizing the major modification of KWRU's existing permit to operate a domestic wastewater facility located at 6630 Front Street, Stock Island, Florida 33040. The Permit at Issue would authorize the expansion of KWRU's existing domestic wastewater facility and the installation of two additional underground injection wells.
Findings Of Fact The Parties Petitioner Last Stand is a not-for-profit corporation incorporated under Florida law. Last Stand has challenged the Permit at Issue in this proceeding. Petitioner George Halloran is a natural person residing in Key West, Florida, and is a member of Last Stand. Halloran has challenged the Permit at Issue in this proceeding. Respondent KWRU is a Florida corporation. KWRU is the wastewater utility service provider that owns and operates the Existing Wastewater Facility2/ and is responsible for its design, construction, operation, and maintenance. It is the applicant for the Permit at Issue in this proceeding. Respondent DEP is the state agency charged with administering the domestic wastewater program in Florida pursuant to chapter 403, Florida Statutes, implementing, as applicable, rules codified at Florida Administrative Code Chapters 62-4, 62-302, 62-303, 62-520, 62-528, 62-600, and 62-620, and various industry standards and manuals incorporated by reference into DEP rules. DEP's proposed agency action to grant the Permit at Issue is the subject of this proceeding. Background and Overview Domestic Wastewater Regulation in the Florida Keys The State of Florida has recognized the need to protect the Florida Keys' unique, sensitive environmental resources. To that end, portions of the Florida Keys are designated, pursuant to statute and by DEP rule, as an Outstanding Florida Water ("OFW"). § 403.061(27), Fla. Stat.; Fla. Admin. Code R. 62-302.700(9). The Florida Legislature also designated the Florida Keys an Area of Critical State Concern. § 380.0552, Fla. Stat. A stated purpose of this designation is to protect and improve the Florida Keys nearshore water quality through construction and operation of wastewater facilities that meet the requirements of section 403.086(10). Additionally, the Florida Legislature has enacted section 403.086(10), which addresses the discharge of domestic wastewater in the Florida Keys. That statute finds that the discharge of inadequately treated and managed domestic wastewater from small wastewater facilities and septic tanks and other onsite systems in the Florida Keys compromises the coastal environment, including the nearshore and offshore waters, and threatens the quality of life and local economies that depend on these resources. Section 403.086(10) directs that after December 31, 2015, all new or expanded domestic wastewater discharges must comply with the treatment and disposal requirements of the statute and DEP rules. Specifically, domestic wastewater treatment facilities having design capacities greater than or equal to 100,000 gallons per day must provide basic disinfection of the wastewater pursuant to DEP rule and must treat the wastewater to a level of treatment, which, on a permitted annual average basis, produces an effluent that contains no more than the following concentrations of the specified constituents: Biochemical Oxygen Demand ("CBOD5") of 5 milligrams per liter ("mg/L"); Suspended Solids of 5 mg/L; Total Nitrogen, expressed as N of 3 mg/L; and Total Phosphorus, expressed as P of 1 mg/L. Collectively, these effluent standards constitute the "advanced wastewater treatment" ("AWT") standards. Section 403.086(10)(e) also imposes requirements regarding disposal of treated domestic wastewater effluent through underground injection. Section 403.086(10)(e)1. requires Class V injection wells serving domestic wastewater treatment facilities having design capacities of less than one million gallons per day (hereafter "MGD") to be at least 90 feet deep and cased to a minimum depth of 60 feet, or to such greater cased depth and total well depth as may be required by DEP rule. Section 403.086(10)(e)2. requires Class V injection wells serving wastewater treatment facilities with design capacities greater than or equal to 1 MGD, excluding backup wells, to be cased to a minimum depth of 2,000 feet or to such greater depth as may be required by DEP rule. The Existing Wastewater Facility KWRU currently is permitted, pursuant to Permit FLA014591 (the "Existing Permit"), to operate a domestic wastewater facility (the "Existing Wastewater Facility" or "Facility")3/ located at 6630 Front Street, Stock Island, Florida. Stock Island is located immediately east and slightly north of Key West. By way of background, KWRU's domestic wastewater system currently consists of three elements: a collection system, which collects wastewater from serviced properties; a transmission system, which transmits wastewater from the collection system to the treatment plant; and the Existing Wastewater Facility, which treats the wastewater and then sends it either as reclaimed water for reuse as irrigation water at the Key West Golf Club, or for toilet flushing or air conditioning makeup water at other facilities specified in the Existing Permit,4/ or disposes of it as treated effluent through two underground injection wells. No modifications to the collection or transmission systems have been proposed or challenged. Thus, only the proposed modifications to the Existing Wastewater Facility are at issue in this proceeding. The Existing Wastewater Facility serves residential and commercial properties located on Stock Island, Florida, immediately adjacent to Key West in the lower Florida Keys. Specifically, the Facility treats domestic wastewater originating from approximately 1,416 existing residential connections and 216 commercial connections. The commercial connections consist of a convalescent center, a college, restaurants, recreational vehicle parks, an animal clinic, and a hospital. There are no industrial wastewater contributors to the Facility. The Facility includes a Category III, Class C wastewater treatment facility operating under the Existing Permit. It is staffed by a Class C or higher operator for six hours a day, seven days per week, in accordance with the Existing Permit and applicable DEP rules. The Facility has a design capacity and a permitted capacity5/ of .499 MGD annual average daily flow ("AADF") and consists of two treatment trains having capacities of .249 MGD and .250 MGD AADF. These treatment trains are piped together to allow operation of the Facility as a single plant. The Facility was upgraded in the mid-2000s and is capable of treating influent wastewater to AWT. However, as authorized under the Existing Permit, the Facility currently treats domestic wastewater to secondary standards, which do not impose nitrogen or phosphorous limits. Under the Existing Permit and in accordance with section 403.086(10), the Facility is not required to meet AWT standards until January 1, 2016. Vacuum and gravity collection systems collect the domestic wastewater from the properties that KWRU services. Wastewater influent from the collection systems flows through the transmission system to a splitter box at the KWRU property, where it is sent to the Facility for treatment. The Facility contains two treatment trains, each consisting of a bar screen, an equalization tank, an aeration tank, an anoxic zone, a post-aeration basin, a clarifier, a silica sand/river rock filter, and a chlorine contact chamber. The bar screens, which constitute the first step in the treatment trains, remove floatables from the wastewater stream. After passing through the bar screens, the wastewater drops into two equalization tanks. As their name indicates, the equalization tanks smooth out the peaks in wastewater flow to the Existing Wastewater Facility. Specifically, wastewater flows to the Facility in large volumes during two periods each day, morning and evening, corresponding with peak water use by the serviced properties. During these large flow volume periods, the equalization tanks fill up with sewage influent, which is meted out during lower-flow periods for treatment by the Facility. In this manner, the Facility treats roughly the same amount of wastewater per hour, which is key to the steady state operation of, and the reliable treatment of the wastewater by, the Facility. From the equalization tanks, the wastewater is directed to the three-stage bioreactor portion of the treatment process. Microorganisms are utilized at each stage to break down the waste. The first stage of the bioreactor process occurs in the aeration basins. Here, wastewater enters the fine-air zone, where it and the microbes used in this stage of the treatment process come into contact with tiny oxygen bubbles. The microorganisms use the oxygen to oxidize the waste and complete the ammonification of the wastewater. The wastewater then passes through bulkheads to the anoxic zones, where the oxygen level is extremely low. In the anoxic zones, bacteria denitrify, or remove nitrogen from, the wastewater. The wastewater is then sent to the post-aeration basins, where excess carbon is removed through oxidation. Thereafter, the wastewater is sent to the clarifiers, where the microorganisms settle out of the wastewater to form a solid precipitate on the bottom of the tank. The precipitate is plowed into a sump and returned by pump to the bioreactors, where the microorganisms are reused in the activated treatment process. When the microorganisms cease to optimally function in treating the waste, they are culled from the treatment process and sent to a digester, where they oxidize, through the endogenous decay process, to the point that they die and only their endoskeletons remain. Sludge, consisting of the endoskeletons and water, is pumped to a sand filter drying bed. The filtrate water is pumped back through the Wastewater Facility to be reused in the wastewater treatment process, while the dried endoskeletons, which are termed "biosolids," are transported offsite for disposal in a Class I landfill. The treated, clarified wastewater is pumped through sand/rock filters, then to the chlorine contact chambers where it is exposed to a minimum of 15 minutes of chlorine disinfection. As noted above, the Existing Permit authorizes the reuse of reclaimed water for, among other uses, irrigation by land application at the 100.27-acre Key West Golf Club golf course. The golf course irrigation system consists, in part, of two unlined interconnected ponds that do not directly discharge to surface waters6/ and that have a storage capacity exceeding one million gallons. KWRU sends reclaimed water to the golf course through its reclaimed water reuse system only in the quantity required to meet the course's irrigation needs. The Existing Permit imposes a minimum residual chlorine level of 1 mg/L and a maximum of 5 mg/L turbidity for the treated wastewater to be considered reclaimed water that can be reused as irrigation at the golf course or as otherwise authorized in the Existing Permit. If the treated wastewater does not meet these standards, switchover/interlock equipment at the Facility disables the power to the pumps that send the reclaimed water offsite for reuse.7/ At that point, the treated wastewater is considered treated effluent.8/ The effluent fills the effluent wet well and is piped directly to the existing underground injection wells for disposal. Pursuant to the Existing Permit, the effluent is disposed of by gravity flow through two Class V, Group 3, ten- inch underground injection wells bored to a depth of 110 feet and cased to a minimum depth of 60 feet. Collectively, the two injection wells have a maximum permitted capacity of .499 MGD AADF. As authorized by the Existing Permit, the underground injection wells discharge the effluent to Class G-III ground water within the Key Largo Limestone.9/ The underground injection wells are not the primary means of disposal for the treated wastewater, in the sense that they are used to remove effluent from the Facility only if and when reclaimed water is not needed by the golf course or the other receiving facilities, or when the treated wastewater does not meet the required residual chlorine and turbidity limits discussed above. The Existing Permit and the activities authorized thereunder are not at issue in this proceeding. Activities Authorized by the Permit at Issue The Permit at Issue proposes to authorize the construction of a new .350 MGD treatment train, which will increase the design capacity and permitted capacity of the plant from .499 MGD to .849 MGD AADF. The proposed modification of the Existing Wastewater Facility entails the addition of a 90-foot diameter tank containing an influent screen, a 105,554-gallon influent equalization tank, a 163,000-gallon aeration chamber, a 154,725-gallon post-anoxic chamber, a 35,525-gallon re-aeration zone, a 112,062-gallon clarifier, and a 317,950-gallon digester. The sand filters and chlorine contact chambers currently in use will be expanded to accommodate flows from the new treatment train, and the chlorine contact chambers will be changed to liquid bleach feed. The Permit at Issue also proposes to authorize the construction and operation of a new .499 MGD AADF underground injection well system consisting of two new Class V, Group 3 ten- inch wells, drilled to a depth of at least 110 feet and cased to a depth of at least 60 feet, which would discharge effluent to Class G-III ground water within Key Largo Limestone. When placed into service along with the two existing injection wells, the total design capacity and permitted capacity of all four underground injection wells would be .998 MGD AADF.10/ The existing reclaimed water reuse system for the Key West Golf Club or the other receiving facilities currently is authorized for a permitted flow capacity of .499 MGD AADF and a design capacity of 1 MGD AADF. The Permit at Issue would authorize the construction of a new reclaimed water reuse system having a permitted capacity of .849 MGD AADF; however, the design capacity of the system remains 1 MGD AADF, and the amount of reclaimed water sent to the golf course for reuse as irrigation is not being changed by the Permit at Issue from that currently authorized by the Existing Permit. Hereafter, the proposed modifications to the Existing Wastewater Facility that are the subject of the Permit at Issue are referred to as the "Project." The expanded facility resulting from completion of the Project is referred to as the "Expanded Wastewater Facility." The Existing Wastewater Facility treatment trains will be modified to meet the AWT standards as of January 1, 2016. Specifically, an alkalinity control system, a carbon injection system, and an alum injection will be added and certain aspects of the wastewater treatment process will be modified as necessary to meet the AWT standard. The new treatment train proposed as part of the Project will be designed to meet the AWT standards upon operation, which will not occur sooner than 2016. Accordingly, as required by section 403.086(10(d)1., all effluent from the Expanded Wastewater Treatment Facility will meet the AWT standards as of January 1, 2016. As a result of conversion of the wastewater treatment process to AWT, and even assuming all treated effluent is injected down the wells, total nitrogen loading will be decreased from 58 pounds per day to 15.9 pounds per day and total phosphorous loading will be decreased from 14.4 pounds per day to 5.3 pounds per day. This is the case even though the volume of effluent disposed of through the wells may as much as double. Only the activities comprising the Project, which are the proposed to be authorized by the Permit at Issue, are the subject of this proceeding. The Permitting Process The overarching purpose of the wastewater facility permitting process, including permitting of modifications to an existing wastewater facility, is to ensure that the wastewater facility does not discharge wastes to any waters of the state without first being given the degree of treatment necessary to protect the beneficial uses of such waters. This is accomplished by requiring the facility to be designed, constructed, and operated in accordance with applicable DEP rule standards, which incorporate industry standards. Fla. Admin. Code R. 62- 600.100(1). Similarly, the overarching purpose of the Underground Injection Well System permitting process is to protect the quality of underground sources of drinking water and prevent degradation of the quality of other aquifers adjacent to the injection zone that may be used for other purposes. This is accomplished by requiring underground injection wells to be designed, constructed, and operated in accordance with applicable DEP rule requirements and standards. Fla. Admin. Code R. 62- 528.100(1). The Wastewater Facility or Activity Permit Application Form 1, General Information, and Application Form 2A, Permit for Domestic Wastewater Treatment and Reuse or Disposal Facility, which are adopted by rule, are the forms that must be completed and submitted to DEP to receive authorization to modify existing wastewater facilities or construct new wastewater facilities. This form includes a list of requirements, some (but not necessarily all) of which apply to proposed modification of an existing wastewater facility. The form requires that a Florida- licensed P.E. certify that the engineering features of the project have been designed by the engineer in conformance with the sound engineering principles applicable to such projects, and that, in his or her professional judgment, the facility, when properly constructed, operated, and maintained, will comply with all applicable statutes and the rules. The Application to Construct/Operate/Abandon Class I, III, or V Injection Well System, which is adopted by rule, is the application form that must be completed and submitted to DEP to receive authorization to construct and operate a Class V Injection Well System. This application form includes a list of requirements, some (but not necessarily all) of which apply to a specific underground injection well construction project. The form requires that a Florida-licensed P.E. certify that the engineering features of the injection well have been designed and examined by the engineer and found to conform to modern engineering principles applicable to the disposal of pollutants as proposed in the permit application. By signing and sealing the application, the P.E. certifies that, in his or her professional judgment, there is reasonable assurance that the injection well, when properly maintained and operated, will discharge effluent in compliance with all applicable statutes and rules. Once the application forms are submitted, DEP permitting staff reviews the applications and determines whether items on the forms and any materials submitted to support those items are incomplete or need clarification. In that event, staff sends the applicant a Request for Additional Information ("RAI"), requesting the applicant to provide additional information to address incomplete or unclear aspects of the application. Once the applicant has provided information sufficient to enable DEP to review the application for issuance or denial of the permit, DEP determines the applications complete and reviews the project for substantive compliance with all applicable statutory and rule permitting requirements. DEP is authorized to issue the permit, with such conditions as it may direct, if the applicant affirmatively provides reasonable assurance, based on the information provided in the application, that the construction, expansion, modification, operation, or activity of the installation will not discharge, emit, or cause pollution in contravention of DEP standards or rules proposed in the application. Fla. Admin. Code R. 62-4.070(1). If the applicant fails to provide such reasonable assurance, the permit must be denied. Conversely, if the applicant provides such reasonable assurance, the applicant is legally entitled to issuance of the permit. Engineering Design of the Project KWRU retained Weiler Engineering Corporation to design the proposed modifications to the Existing Wastewater Facility and the new underground injection well (again, collectively referred to as the "Project") and to prepare and submit the applications for the Permit at Issue to DEP. Edward Castle and Christopher Johnson prepared the applications for the Permit at Issue. As the applicant, Johnson signed the application documents as required pursuant to the application form. As the engineer of record, Castle signed and sealed the certifications in the application forms, representing that he was the engineer in responsible charge of preparing the Project's engineering documents. Castle's signature and seal on the application forms for the wastewater treatment facility expansion portion of the Project constitute his representation that he designed and examined the engineering features of the wastewater treatment facility expansion; that these features conform to sound engineering principles applicable to the Project; and that, in his professional judgment, the wastewater treatment facility expansion portion of the Project, when properly constructed, operated, and maintained, will comply with all applicable statutes and rules, including the requirement that the effluent meet the AWT standards as of January 1, 2016. Similarly, Castle's signature and seal on the application to construct the new underground injection wells constitute his representation that he designed the engineering features of these injection wells; that the injection wells conform to modern engineering principles applicable to the disposal of pollutants as proposed in the permit application; and that in his professional judgment, there is reasonable assurance that the wells, when properly maintained and operated, will discharge effluent in compliance with all applicable statutes and rules, including the requirement that the effluent discharged through the injection wells meet AWT standards as of January 1, 2016. As previously noted, the design capacity of wastewater treatment portion of the Expanded Wastewater Facility is proposed to be .849 MGD AADF. Castle selected this design capacity based on historic wastewater flows at the Existing Wastewater Facility and foreseeable projected wastewater treatment capacity demand in the future.11/ Specifically, to estimate future capacity demand, Castle considered development agreements, requests for utility service, the existence of scarified property and applicable development density, wetslips, recent property sales, and estimated and proposed in-fill development on Stock Island. He projected residential development wastewater treatment demand based on historic actual flow data from the Monroe County Sanitary Wastewater Master Plan ("Master Plan"), in conformance with the Recommended Standards for Wastewater Facilities, the so- called "Ten States Standards," a wastewater systems design and planning guidance document incorporated by reference in rule 62- 600.300(4). Additionally, Castle applied the estimated sewage flows codified in Florida Department of Health rule 64E-6.008, Table I, System Design Estimated Sewage Flows ("DOH Table I"), to estimate wastewater treatment demand for projected commercial and hotel development uses. Once Castle had projected wastewater capacity demand for residential and hotel/commercial uses at buildout on Stock Island, he factored in an additional 15 percent capacity safety factor to derive the .849 MGD AADF design capacity for the Expanded Wastewater Facility. Castle chose AADF, rather than the maximum monthly average daily flow or three-month average daily flow, as the timeframe for the design capacity based on historical flow amounts to the Existing Wastewater Facility and because of insignificant seasonal variations in historical flows to the Facility.12/ This is because the population on Stock Island contributing flow to the Existing Wastewater Facility is largely comprised of non-seasonal residents and commercial operations.13/ Nonetheless, to ensure the Expanded Wastewater Facility will have adequate capacity to effectively treat wastewater to the required standards during higher flow periods that may result from non- residential seasonal occupancy in the future, Castle assumed year-round, 100 percent occupancy for the projected hotel and commercial development on Stock Island in determining the design capacity for the Expanded Wastewater Facility. Castle estimated a peak hourly flow of 1.273 MGD for the Expanded Wastewater Facility. This figure estimates the maximum flow through the facility on an hourly basis specifically to take into account the diurnal variability of wastewater flow entering the facility. By definition, the peak hourly flow is a maximum hourly flow rather than the sustained flow or volume into or through the facility. The projected maximum hourly flow of 1.273 MGD, which was determined by multiplying the annual average daily flow by a peaking factor of 1.5, is an estimate of the maximum hourly flow wastewater coming into the Expanded Wastewater Facility's equalization tanks. Importantly, it is not the volume of wastewater flow, on an annual average daily basis, that will leave the facility's equalization tanks and flow through the facility's treatment process. Put another way, the 1.273 MGD peak hourly flow is not the Expanded Wastewater Facility's design capacity. As previously noted, the permitted capacity of the wastewater treatment portion of the Expanded Facility also would be .849 MGD AADF. The permitted capacity is the amount, on an annual average daily flow basis, that the wastewater treatment portion of the Expanded Wastewater Facility is authorized to treat and discharge. This metric establishes an absolute limit, on an annual average daily basis, on the quantity of wastewater that can be treated by, and discharged from, the Expanded Wastewater Facility. Also as discussed above, once the two new underground injection wells are installed, the total design capacity of the four wells at the Expanded Wastewater Facility will be .998 MGD AADF. The two new injection wells are being added to ensure adequate disposal capacity for the .849 MGD permitted capacity and, importantly, to accommodate the peak hourly flow. The reclaimed water reuse system currently has an authorized design capacity of 1 MGD AADF, and this is not being changed by the Project, although the permitted capacity is being increased to .849 MGD AADF. As discussed in greater detail below, neither the design capacity nor the permitted capacity of the reuse system is a function of the irrigation application rate per acre of the golf course, and neither represent the amount of irrigation applied to the golf course per day. In determining the design capacity for the Expanded Wastewater Facility, Castle considered wastewater capacity demand for the facility through the year 2020, rather than over a 20- year period. This is because buildout of the properties on Stock Island that will contribute flow to the facility is reasonably projected to occur between 2018 and 2020. After buildout, there will be no additional properties being developed to contribute additional wastewater flows to the Expanded Wastewater Facility. The credible, persuasive evidence establishes that the proposed design capacity of .849 MGD AADF for the Expanded Wastewater Facility is appropriate under rule 62-600.200(19) and other pertinent provisions in chapter 62-600 and conforms to sound engineering principles applicable to the Expanded Wastewater Facility. The credible, persuasive evidence also establishes that the proposed permitted capacity of .849 MGD AADF for the Expanded Wastewater Facility is appropriate under rule 62- 600.200(62) and other pertinent provisions of chapter 62-600 and conforms to sound engineering principles applicable to the Expanded Wastewater Facility. The credible, persuasive evidence further establishes that the Project, when properly constructed, operated, and maintained, will comply with all applicable statutes and rules, including the requirement that the effluent meet the AWT standards as of January 1, 2016. The credible, persuasive evidence also establishes that the underground injection wells, as designed, conform to modern engineering principles applicable to the disposal of pollutants as proposed in the permit application; and that there is reasonable assurance that the wells, when properly constructed, maintained, and operated, will discharge effluent in compliance with all pertinent statutes and rules, including the requirement that the effluent discharged down the injection wells meet AWT standards as of January 1, 2016. DEP Review and Proposed Issuance of the Permit at Issue The wastewater treatment facility and underground injection well applications for the Project were submitted to DEP on April 15, 2014. During DEP's review of the applications for the Project, the question arose whether the 1.273 MGD peak hourly flow stated in the permit application would trigger the so-called "deep well" requirement in section 403.086(10)(e)2. that the underground injection wells be cased to a minimum depth of 2,000 feet. DEP ultimately concluded that the term "design capacity," as used in the statute, referred to an average daily flow rate14/ over a specified period of time——here, a year——for the Expanded Wastewater Facility, rather than the transient peak hourly flow for the facility. Thus, the Expanded Wastewater Facility does not have a design capacity exceeding 1 MGD, so the deep well requirement in section 403.086(10)(e)2. does not apply to the Expanded Wastewater Facility. DEP permit review staff issued one RAI, and KWRU timely provided the requested information. Upon receipt and review of KWRU's response to the RAI, DEP deemed the application for the Permit at Issue complete. DEP staff reviewed the permit applications for compliance with applicable statutory and rule requirements and standards. DEP's review does not entail re-designing or re- engineering the project or questioning the design engineer's reasonable exercise of judgment on design matters, as long as the project is accurately designed based on sound engineering principles and will operate in accordance with the applicable permitting requirements and standards. Thus, as a matter of practice, DEP relies, to a large extent, on the design engineer's certification that the system is accurately designed according to sound engineering principles——as is appropriate and authorized pursuant to the certification provisions on the application forms, rule 62-4.050(3), and chapter 471 and Florida Board of Engineering rules.15/ Gary Maier, P.E., professional engineer supervisor III and supervisor of DEP's domestic wastewater facility permit review staff, also reviewed the applications, the Intent to Issue, and the draft Permit at Issue to ensure that the Project complied with all applicable rules and standards and that KWRU had provided reasonable assurances such that the Project should be approved. Ultimately, DEP determined that KWRU provided reasonable assurances that the relevant permit applications met the applicable statutory and rule requirements and standards. Accordingly, DEP issued a Notice of Intent to issue the Permit at Issue. Establishment of Prima Facie Entitlement to Permit at Issue The relevant portions of the permit file, including the permit applications, supporting information, and Notice of Intent to Issue for the Permit at Issue, were admitted into evidence at the final hearing. With the admission of these documents into evidence, KWRU established its prima facie case demonstrating entitlement to the Permit at Issue. See § 120.569(2)(p), Fla. Stat. Challenge to the Permit at Issue Once KWRU demonstrated prima facie entitlement to the Permit at Issue, the burden shifted to Petitioners to present evidence proving their case in opposition to the Permit at Issue. See id. To prevail in this proceeding, Petitioners bear the ultimate burden of persuasion to prove their case by a preponderance of the competent substantial evidence. Petitioners have raised numerous grounds in the Second Amended Verified Petition for Formal Administrative Hearing16/ that they contend mandate denial of the Permit at Issue. Each of these grounds is addressed below. Alleged Permit Application Deficiencies Petitioners contend that the Permit at Issue should be denied due to alleged deficiencies in the applications submitted for the Project. Capacity Analysis Report Petitioners allege that, under rule 62-600.405, KWRU was required to submit a Capacity Analysis Report ("CAR") as part of its application for the Permit at Issue and that its failure to do so renders the applications incomplete, thus requiring denial of the Permit at Issue. The purpose of a CAR is to analyze capacity at an existing wastewater facility and to apprise DEP when it becomes evident that expansion of the wastewater facility may be needed. Specifically, the CAR is performed and submitted on a periodic basis, or when certain contingencies occur, to apprise DEP of the actual flows through the facility. If the actual flows are approaching the facility's permitted capacity, the CAR serves to notify DEP that expansion of the facility may be warranted. Thus, the CAR helps ensure that the permittee recognizes the need for, and properly plans for, future expansion of the facility. In support of their contention, Petitioners presented the testimony of William Lynch, a Florida-licensed P.E., who has experience in the planning and design of wastewater treatment facilities in Florida, including the Florida Keys. Lynch testified that the most recent three-month average daily flows reported to the DEP by KWRU repeatedly exceeded 50 percent of the permitted capacity of the Existing Wastewater Facility, thereby triggering the requirement in rule 62-600.40517/ that a CAR be submitted. KWRU previously submitted an initial CAR when the Existing Wastewater Facility historically exceeded 50 percent of its permitted capacity. Thereafter, KWRU submitted an updated CAR in April 2012, as part of the renewal application for the Existing Permit that KWRU filed in October 2011. The April 2012 CAR indicated that permitted flows would not be exceeded for ten years. Thus, under rule 62-600.405(5), a subsequent updated CAR would be due at five year intervals or when the applicant applied for an operation permit or renewal of an operation permit, whichever occurred first.18/ The persuasive evidence establishes that during the period between issuance of the Existing Permit in February 2012 and submittal of the applications for the Permit at Issue in 2014, the three-month average daily flows for the Existing Facility had not exceeded 50 percent of the treatment plant's capacity and the five-year interval CAR submittal interval (which would have expired in 2017) had not yet expired, so an updated CAR was neither required nor submitted. When development on Stock Island resumed in the 2012 through 2014 timeframe following an economic recession, it became apparent from actual flow data that the Existing Wastewater Facility would need to be expanded to accommodate the wastewater flow from new development, as well as to accommodate wastewater flow from existing development being required by law to connect to a central wastewater system. Accordingly, in April 2014, KWRU submitted the applications for the Permit at Issue. As part of KWRU's applications, the design and permitted capacity of the Existing Wastewater Facility were analyzed, and future wastewater flows for the facility were projected, taking into account all relevant factors, including projected development over an appropriate planning period, new connections from existing development, and the lack of seasonal variation in historic flows. Based on this information, the proposed design and permitted capacities for the Expanded Wastewater Facility were determined. This information is precisely that which would have been required in an updated CAR. Because all pertinent information necessary to determine the design and permitted capacities for the Expanded Wastewater Facility was submitted as part of the applications for the Permit at Issue, a separate CAR was not required and, indeed, would have been redundant and pointless. It should be noted that the Permit at Issue specifically requires submittal of a CAR upon renewal, which is five years from the date of issuance. Further, the Expanded Wastewater Facility is subject to chapter 62-600, including rule 62-600.405, so KWRU would be required to submit a CAR if circumstances specified in the rule were to occur.19/ Thus, Petitioners failed to demonstrate, by a preponderance of the competent substantial evidence, that a CAR was required to be submitted as part of applications for the Permit at Issue. Accordingly, the absence of a CAR as part of the applications is not a basis for denying the Permit at Issue. Deep Injection Well Requirement Petitioners contend that the design capacity for KWRU's wells exceeds 1 MGD, so KWRU was required under section 403.086(10)(e)2. to apply for approval to install deep injection wells——i.e., wells that are cased to a minimum depth of 2,000 feet. Petitioners further contend that KWRU's failure to include an application for deep injection wells in its applications thus mandates denial of the Permit at Issue. Under section 403.086(10)(e)1., injection wells serving wastewater facilities that have a design capacity of less than 1 MGD are required to be at least 90 feet deep and cased to a minimum depth of 60 feet. Under section 403.086(1)(e)2., injection wells serving wastewater facilities having a design capacity equal to or greater than 1 MGD must be cased to a minimum depth of 2,000 feet or such greater depth as may be required by DEP rule. As previously discussed, rule 62-600.200(19) defines "design capacity" as "the average daily flow projected for the design year which serves as the basis for the sizing and design of the wastewater facilities." The rule states that the design capacity is established by the permit applicant, and that the timeframe associated with the design capacity——such as annual average daily flow, maximum monthly average daily flow, or three- month average daily flow——also is specified by the applicant. Additionally, rule 62-600.400(3)(a), which is part of DEP's Design Requirements rule for domestic wastewater facilities, reiterates that the applicant establishes both the design capacity and the timeframe used to define its selected design capacity, with the caveat that the timeframe selected must reflect seasonal variations in flow, if any. As discussed above, the credible, persuasive evidence establishes that KWRU's selected design capacity and timeframe ——here, .849 MGD AADF——accurately and appropriately addresses the projected wastewater flows that will be treated by the Expanded Wastewater Facility. As Castle credibly testified, historical flows to the Existing Wastewater Facility do not indicate substantial seasonal residential flow, consistent with the workforce population residing year-round on Stock Island. Moreover, to the extent there may be some seasonal flow variation associated with projected hotel and commercial development, Castle took that into account in determining the design capacity for the Expanded Wastewater Facility. For these reasons, Castle's selection of AADF as the design capacity metric is appropriate, conforms to sound engineering principles, and complies with applicable DEP rules. Further, as previously discussed, the 1.273 MGD peak hourly flow is exactly that——the peak or maximum flow expressed on an hourly basis——that can be processed by the Expanded Wastewater Facility. It does not constitute the design capacity of the Expanded Wastewater Facility, which, by definition, is the average flow over a specified period of time. The persuasive evidence in the record shows that the proposed design capacity of the Expanded Wastewater Facility is .849 MGD AADF, and this design capacity is appropriate and based on sound engineering principles. As such, the design capacity of the facility is less than 1 MGD, so the deep well requirement in section 403.086(10)(e)2. does not apply to the Project. Thus, Petitioners failed to demonstrate, by a preponderance of the evidence, that the deep well requirement in section 403.086(10)(e)2. applies to the Project. Accordingly, they did not establish that the Permit at Issue should be denied on the basis that KWRU did not apply for approval of deep injection wells as part of the applications for the Project. Identity of Permittee The Permit at Issue is proposed to be issued to Key West Resort Utilities Corporation, which is not an existing entity registered to do business in Florida or in any other state. Petitioners contend, and KWRU and DEP do not dispute, that a permit issued to an entity that does not legally exist cannot legally authorize any activities. Accordingly, to the extent the Permit at Issue is proposed to be issued to Key West Resort Utilities Corporation, Petitioners contend that this constitutes a basis for denying the Permit at Issue. At the hearing, DEP and KWRU presented credible evidence showing that the correct permittee is KW Resort Utilities Corp., not Key West Resort Utilities Corporation as was stated on the proposed Permit at Issue. Further, the permit applications correctly identify KWRU as the applicant for the Permit at Issue. Thus, identification of Key West Resort Utilities Corporation as the permittee on the proposed Permit at Issue was a typographical error, and the evidence establishes that this error will be corrected when the Permit at Issue is issued. If this typographical error is corrected, then the Permit at Issue should not be denied on this basis. Alleged Project Design and Engineering Deficiencies Petitioners allege that KWRU failed to provide reasonable assurance, based on a preliminary design report, plans, test results, installation of pollution control equipment, or other information, that the construction, modification, or operation of the Expanded Wastewater Facility will not discharge or cause pollution in contravention of chapter 403 and applicable DEP rules. Petitioners further allege that KWRU has undersized the design capacity of the Expanded Wastewater Facility and that the appropriate design capacity is greater than 1 MGD, thus triggering the deep well requirement in section 403.086(10)(e)2. Projected Flows to Expanded Wastewater Facility In support of their position, Petitioners presented the testimony of William Lynch, a Florida-licensed P.E., who testified that the future wastewater flows to the Expanded Wastewater Facility projected by KWRU in its applications are incorrect because they do not accurately address planned development in KWRU's service area, as required by the Ten States Standards. Lynch took the position that pursuant to the Ten States Standards, the appropriate planning horizon for the Project is at least ten years, which would require KWRU to project wastewater flow to the Expanded Wastewater Facility through approximately 2025, rather than through 2020, as projected in the applications for the Project. However, the persuasive evidence shows that KWRU utilized an appropriate planning horizon in projecting future wastewater flows to the Expanded Wastewater Facility. KWRU's facility design engineer, Castle testified, persuasively, that although the graphic submitted in the application shows the projected wastewater flows only through the year 2020, the planning horizon he used actually was infinite. This is because the projected buildout of the service area20/ to maximum wastewater flow is anticipated to occur between 2018 and 2020, and after that point, wastewater flows to the facility would remain constant. Thus, it was pointless to depict projected flows out to the year 2025——particularly since the narrative in the application describing the Project makes clear that buildout of KWRU's service area is anticipated to occur by 2020. Because the wastewater flows projected for the year 2020 accurately represent the maximum flows that the Expanded Wastewater Facility can process, the projected planning horizon to the year 2020 is appropriate for the facility, complies with the Ten States Standards, and complies with DEP rules. Lynch also asserted that the projected wastewater flows to the Expanded Wastewater Facility from development identified in the application do not accurately apply the standards in DOH Table I and that this inaccuracy further contributed to underestimation of the design capacity of the Expanded Wastewater Facility. Lynch arrived at this position by applying Table I to all identified future development——both residential and nonresidential——and considering an additional development (Key West Harbor Yacht Club) not listed in the applications. He projected that the future wastewater flow from these developments would be approximately 146,110 gallons per day——approximately 46,000 gallons per day higher than the 100,000 gallons per day that Lynch claimed KWRU projected for the planned developments on Stock Island. Based on the addition of 46,000 gallons to KWRU's proposed design capacity of .849 MGD, Lynch opined that .895 MGD is the design capacity that should have been proposed for the Expanded Wastewater Facility. However, the credible, persuasive evidence establishes that, in determining the design capacity of .849 MGD for the Expanded Wastewater Facility, Castle accurately projected the wastewater flow quantities from future development on Stock Island. Castle described in detail the process he undertook to determine the projected wastewater flows from the various land uses and locations on Stock Island through projected buildout between 2018 and 2020. Specifically, he identified planned nonresidential development on Stock Island expected to begin producing wastewater flows in 2014 and applied the DOH Table I standards to determine the projected flows for each development. To determine projected wastewater flow from future residential development on Stock Island, Castle identified approximately 40 acres of scarified or under-utilized property in KWRU's service area and applied a density of 12 equivalent dwelling units ("EDU") per acre,21/ with 167 gallons per day of wastewater flow attributable to each EDU, using actual historic wastewater flow data from the Master Plan. Additionally, for each scarified or under-utilized property having water frontage, he projected one boat slip per 35 feet of frontage and applied a 75-gallon-per-day flow for each boat slip using DOH Table I recreational vehicle flows. For years 2016 through 2019, Castle projected incremental increases in wastewater flows per year22/ to account for potential development of other currently occupied properties. The aggregate of all projected flows from the identified developments, the 40 acres and boat slips, and the incremental increases per year through buildout yielded a projected wastewater flow of .74 MGD to the Expanded Wastewater Facility by years 2018 through 2020, which represents buildout flow to the facility. Castle then added a "safety factor" of 15 percent to the projected .74 MGD wastewater flow to accommodate currently unknown future redevelopment of existing occupied properties, to reach the .849 MGD design capacity. The 46,000-gallon discrepancy between Lynch's .895 MGD design capacity calculation and Castle's .849 MGD design capacity calculation is attributable to four basic differences in how they each determined design capacity. First, Lynch used more recent development agreement and development order information that more precisely identified and quantified specific land uses than the information that KWRU had available to it at the time it prepared and submitted its application. However, the evidence did not establish that the flow information on which Lynch relied and that on which Castle relied were so appreciably different as to significantly affect the projected design capacity for the Expanded Wastewater Facility. Second, Lynch applied DOH Table I to project future wastewater flows from all future planned development on Stock Island, both residential and nonresidential, whereas Castle applied DOH Table I only to determine nonresidential development future flows, and used actual historic flow data from the Master Plan to determine residential development future flows. Castle's residential flow calculation using historical actual flow data conforms to the recommendation in section 11.242(a) of the Ten States Standards that actual flow data be used, to the extent possible, to predict future flows; thus, Castle's calculation likely more precisely projects future flow attributable to residential development on Stock Island.23/ Third, Lynch took into account the Key West Harbor Yacht Club flow into the Expanded Wastewater Facility, whereas KWRU did not consider this flow in projecting future flows to the facility. This omission constituted an oversight on KWRU's part, and the flow from this development should have been included in the wastewater flow projection for the facility. However, the persuasive evidence did not show that this omission constituted a significant error in KWRU's .849 MGD AADF design capacity projection.24/ Fourth, Lynch apparently misinterpreted a statement in the application referencing "such redevelopment" as referring to the known planned developments on Stock Island, which were specifically identified by name in the application, and, thus, interpreted the reference to 100,000 gallons as being the flow KWRU projected for those known, named developments. However, the persuasive evidence established that the 100,000 gallons that KWRU assigned to "such redevelopment" in its application referred not to the known, named developments identified in the application, but instead to presently unknown future development on Stock Island, which Castle took into account by including the 15 percent "safety factor" in determining design capacity. Pursuant to the foregoing, it is determined that KWRU demonstrated, by credible, persuasive evidence, that it accurately estimated future wastewater flows from projected development on Stock Island to determine an appropriate design capacity of .849 MGD AADF for the Expanded Wastewater Facility. Design Capacity Timeframe Petitioners allege that the timeframe associated with the design capacity specified by KWRU——the annual average daily flow, or AADF——is not appropriate for the Expanded Wastewater Facility because it fails to reflect seasonal flows to the facility as required by rules 62-600.200(16) and 62-600.400(3)(a). Petitioners assert that the design capacity for the facility should instead be expressed in maximum monthly average daily flow ("MMADF") to account for seasonal flows. In support, Petitioners presented the testimony of Lynch, who opined that the KWRU service area experiences seasonal flows driven by the influx of tourists to Stock Island during tourist season. Lynch based this opinion on the wastewater flow data for the Existing Wastewater Facility for the year 2014, and his calculations showing that the three-month average daily flow ("ADF") for October through December 2014 was 11 percent higher than the AADF and that the MMADF for that period was 16 percent higher than the AADF. Lynch considered this variation substantial enough to indicate seasonality, so that MMADF is the appropriate design capacity timeframe for the Expanded Wastewater Facility. Using MMADF as the design capacity timeframe, Lynch opined that the design capacity of the Expanded Wastewater Facility should be 1.04 MGD MMADF——which would trigger the deep well requirement in section 403.086(10)(e)2. Castle chose AADF as the timeframe for the Expanded Wastewater Facility design capacity because historical flow records over a period of years do not show significant seasonal variations in flow for Stock Island. Castle testified, credibly and persuasively, that while the historical flow data shows a consistent slight increase in flows from August to December, in his view, the variation is not significant enough to constitute a seasonal flow. This is consistent with the evidence establishing that Stock Island is a "bedroom community" having a mostly year- round workforce population. Lynch formulated his opinion regarding appropriate design capacity using 2014 flow data for the entire year, which was not available at the time KWRU filed its permit applications for the Project in April 2014. Although Lynch relied on more recent data, his opinion was based only on one year of data. By contrast, Castle selected AADF as the design capacity metric based on the previous five years of flow data, which showed variations in flow ranging between two percent and 12 percent on a three-month average daily flow basis. Castle credibly testified that these variations were not significant enough to indicate seasonal flows and did not closely correlate with tourist season in the Keys. Additionally, in calculating his flow projections for the Expanded Wastewater Facility, Castle assumed 100 percent year-round occupancy for residential units, so that his projected design capacity of .849 MGD necessarily took into account potential seasonal flows. Thus, to the extent there are seasonal flows, the facility simply will receive flows below the design capacity during off-season. The undersigned finds Castle's use of long-term historical flow data more reliable than Lynch's use of only one year of data in assessing whether there is flow seasonality.25/ DEP's wastewater permitting supervisor, Gary Maier, concurred that the variations in wastewater flow do not reflect a significant seasonal variation that would require the use of a smaller averaging period than AADF. Maier also observed that none of the wastewater facilities in the Florida Keys having a design capacity greater than 100,000 gallons per day has a design capacity based on MMADF. This evidences that Castle's selection of AADF as the timeframe metric conforms to the design capacity standard used for facilities of comparable size in the Florida Keys. Based on the foregoing, it is determined that KWRU's selection of AADF as the design capacity timeframe metric for the Expanded Wastewater Facility is appropriate and complies with DEP rules. Petitioners failed to demonstrate that KWRU's selection of AADF as the design capacity timeframe metric violates any applicable laws or rules. Accordingly, Petitioners did not demonstrate that the Permit at Issue should be denied on this basis. Ability of Expanded Wastewater Facility to Reliably Meet AWT Petitioners further allege that KWRU failed to provide a complete application demonstrating that the treatment processes for the Expanded Wastewater Facility will efficiently and reliably meet effluent limitations for design year flow. As discussed above, the evidence establishes that KWRU provided all of the information required for the applications for the Permit at Issue, so DEP correctly determined that the applications were complete before commencing its substantive review of the applications. Also as discussed above, Lynch opined that the proposed design capacity was undersized for the flows he projected for the Expanded Wastewater Facility. However, the persuasive evidence shows that KWRU's proposed design capacity of .849 MGD AADF is appropriate, conforms to sound engineering principles, and meets applicable statutory and rule requirements. In order to ensure that a wastewater facility functions effectively and reliably, it is important that the facility not be substantially oversized for the amount of wastewater flowing into the facility. In an over-sized facility, inconsistent timing of wastewater flow, lack of appropriate chemical environment for waste breakdown, and inadequate food supply for the microorganisms may lead to ineffective performance of the facility. A consequence of these imbalances is that undesirable microbes may populate the facility, causing incomplete solids settlement, overflow of solids downstream to the filters, and operational problems resulting in failure of the facility to treat wastewater to AWT standards. KWRU provided reasonable assurance, based on the proposed .849 MGD AADF design capacity and the other engineering features of the Project, that the Expanded Wastewater Facility is appropriately sized and will effectively and reliably treat the wastewater to AWT standards. Thus, Petitioners failed to prove that the Permit at Issue should be denied on the basis that it is undersized and will not reliably meet AWT standards. Key West Golf Club Reuse System Issues Petitioners contend that as part of the applications for the Project, KWRU proposes to send 1 MGD of reclaimed water to the golf course. Petitioners claim that, given an irrigated area of 100.27 acres and an average irrigation rate of .73 inches per acre per day, only 300,000 gallons of reclaimed water per day is accounted for by reuse as irrigation. On that basis, Petitioners allege that KWRU has not demonstrated that the 700,000 gallon-per-day balance of reclaimed water sent to the golf course will be reused for a beneficial purpose rather than being disposed. This contention is based on a misunderstanding of the structure and function of the reuse system. The 1 MGD flow stated in the permit application is the design capacity of the reuse system, which is not being changed by the Permit at Issue. Importantly, this figure does not quantify the amount of water that is or actually will be sent to the golf course or applied as irrigation to the golf course irrigated area in a single day. Rather, it represents the flow capacity to which the reuse system is designed.26/ The applications for the Permit at Issue do not propose any changes to the quantity of reclaimed water being reused, which is governed by the irrigated acreage at the golf course and the irrigation rate. These parameters are not being changed. As previously discussed, KWRU sends reclaimed water to the golf course only on an as-needed basis, where it is stored in the ponds until needed for irrigation. If the course does not need reclaimed water sent to the ponds, KWRU does not send the water. Thus, the golf course controls the amount of reclaimed water that is sent to the storage ponds. Although the permitted capacity of the reuse system is being expanded from .499 MGD AADF to .849 MGD AADF, the actual amount of reclaimed water sent to the golf course by KWRU is not anticipated to change because, as discussed above, the amount being reused for irrigation is not being changed. Since the amount of reclaimed water being reused for irrigation is not increasing, the reuse system is not being expanded. Thus, the evidence does not show that 700,000 gallons per day of reclaimed water will be sent to the golf course for disposal, inconsistent with rule 62-610.810(2), rather than being reused for a beneficial purpose.27/ Petitioners also assert that the increased permitted capacity of the reuse system constitutes a "new or expanded reuse or land application project," so that an engineering report and reuse feasibility study were required as part of the applications for the Permit at Issue, pursuant to rule 62-610.310(1). KWRU previously provided these documents when it originally applied for authorization of the reuse system. The credible, persuasive evidence shows that increasing the permitted capacity of the reuse system does not trigger the requirement to submit another engineering report or reuse feasibility study. This is because no changes to the structural components or operation of the reuse system facilities are proposed. As Castle credibly explained, and Maier confirmed, the relevant question in determining whether an engineering report is required is whether the land application rate and/or the irrigated acreage is being changed, which would increase the amount of reclaimed water being reused and, thus, would require expansion of the reuse system. As discussed, neither the irrigated area nor the irrigation application rate is proposed to change under the Project. Thus, neither an engineering report nor a reuse feasibility study are required as part of the applications for the Permit at Issue. Therefore, Petitioners failed to demonstrate that the Permit at Issue should be denied on the basis that KWRU did not submit a reuse feasibility or engineering report as part of its applications for the Permit at Issue. Alleged Surface Water Quality Violations by Injection Wells Petitioners allege that disposing of the effluent from the Expanded Wastewater Facility through the injection wells will cause or contribute to violations of surface water quality standards codified in chapter 62-302. Petitioners further allege that, as a consequence, the discharge will violate antidegradation requirements in rules 62- 4.242, 62-302.300, and 62-302.700(1), and that the wells do not comply with the underground injection control rule requirement in rule 62-528.630(7), specific to Monroe County, that the wells not cause or contribute to surface water quality violations. Regulatory Status of Surface Waters in Stock Island Vicinity A significant portion of the surface waters in the Florida Keys, including those surrounding Stock Island and Key West, are classified as Class III surface waters pursuant to rule 62-302.400. Water quality criteria adopted by rule for Class III surface waters are established to protect fish consumption, recreation, and the propagation of a healthy, well- balanced population of fish and wildlife. As previously noted, certain portions of the Florida Keys, including the surface waters surrounding Stock Island and Key West, are designated an OFW. Fla. Admin. Code R. 62- 302.700(9)(i)13. No degradation of surface water quality, other than that allowed under rules 62-4.242(2) and (3), is permitted in an OFW. See Fla. Admin. Code R. 62-302.700(1). The narrative nutrient criterion codified at rule 62- 302.530(47)(a) states: "[t]he discharge of nutrients shall be limited as needed to prevent violations of other standards contained in this chapter. Man-induced nutrient enrichment (total nitrogen or total phosphorus) shall be considered degradation in relation to the provisions of Rules 62-302.300, 62-302.700, and 62-4.242, F.A.C." The narrative nutrient criterion codified at rule 62-302.530(47)(b) states: "[i]n no case shall nutrient concentrations of a body of water be altered so as to cause an imbalance in natural populations of aquatic flora or fauna." These criteria apply in Class III surface waters, including the surface waters in and around the Florida Keys. See Fla. Admin. Code R. 62-302.531(1). Rule 62-302.531(2) requires DEP to numerically interpret the narrative nutrient criterion for nutrients (nitrogen and phosphorus) and for nutrient response (chlorophyll- a). Where a site-specific numeric interpretation of rule 62- 302.530(47)(b) has been established, that numeric interpretation constitutes the primary standard applicable to that site. Fla. Admin. Code R. 62-302.531(2)(a). A range of natural factors affect nutrient loading for a given waterbody. Therefore, site- specific numeric interpretations of the narrative nutrient criteria generally are deemed more reliable than broadly applicable, non-site specific criteria. Estuary-specific numeric interpretations of the narrative nutrient criterion in rule 62-302.530(47)(b), consisting of nutrient values for nitrogen and phosphorus and a nutrient response value for chlorophyll-a have been adopted for many areas in the state of Florida, including the Florida Keys. These numeric interpretations——commonly referred to as "numeric nutrient criteria," or "NNCs"——are open water, area-wide averages. See Fla. Admin. Code R. 62-302.532(1). For the Florida Keys, seven Florida Keys Marine Nutrient Regions ("FKMNRs") have been identified and geographically delineated on a series of maps adopted by rule. For each of these FKMNRs, NNCs have been adopted for nitrogen, phosphorus, and chlorophyll-a. Fla. Admin. Code R. 62- 302.532(1)(g). The NNCs for the Lower Keys Region and the Back Bay Region are germane to this proceeding. For the Bay Back Region, the NNCs are .009 mg/L for phosphorus, .25 mg/L for nitrogen, and .3 µg/L for chlorophyll-a. For the Lower Keys Region, the NNCs are .008 mg/L for phosphorus, 0.21 mg/L for nitrogen, and 0.3 µg/L for chlorophyll-a. These NNCs are expressed as annual geometric means that are not to be exceeded more than once in a three-year period.28/ The area of water extending from the shoreline out to 500 meters offshore in the Florida Keys is referred to as the "Halo Zone." DEP has adopted by rule a map delineating the Halo Zone. The NNCs applicable to surface waters in each of the FKMNRs currently do not apply to the surface waters in the Halo Zone. Thus, only the narrative nutrient criteria codified at rules 62-302.530(47)(a) and (b) apply to surface waters in the Halo Zone at this time.29/ Additionally, pursuant to chapter 62-303, the Impaired Waters Rule, DEP has identified and delineated spatial assessment areas in waterbodies based on homogeneity for multiple water quality parameters.30/ These assessment areas, called "Waterbody IDs" or "WBIDs," are delineated for purposes of assessing, through water quality sampling, whether the surface waters within the WBID are impaired——that is, whether they fail to meet one or more of the applicable water quality standards due to pollutants.31/ DEP has delineated several WBIDs, identified by number, in the Halo Zone surrounding Key West and Stock Island. The Halo Zone surrounding Stock Island comprises WBID 6014B, and the Halo Zone surrounding Key West consists of WBIDs 6014A and 8073A through 8073H.32/ The Back Bay Region, which is located north of Stock Island and outside of the Halo Zone, is designated as WBID 8074. The Lower Keys Region consists of WBID 8073, which is located northwest of Stock Island and surrounding Key West outside of the Halo Zone, and WBID 8079, which is located south of Stock Island outside of the Halo Zone. Water quality monitoring, consisting of sampling for a range of parameters, is conducted at monitoring stations within each of these WBIDs. At least one monitoring station is located within each WBID. This water quality sampling is conducted according to DEP's applicable standard operating procedures. The monitoring stations have collected nutrient and nutrient response data spanning a period of years. The data collected in 1995 through 2013 are pertinent to this proceeding.33/ The Keys RAP, which was prepared in 2008 and updated in 2011, prescribes specific management activities to be implemented to restore surface water quality in the Florida Keys, including eliminating cesspits and onsite septic tank systems and connecting wastewater generators to centralized wastewater systems that treat the wastewater to AWT standards. As authorized under rule 62-303.600, DEP determined that the Keys RAP provides reasonable assurance that the restoration goals for the surface waters in the Florida Keys will be achieved by ensuring that all management activities specified in the Keys RAP would be implemented for specified waterbodies by 2015. Accordingly, in February 2012, DEP approved and adopted the Keys RAP by Secretarial Order. Current and historic water quality data show that all WBIDs in the Keys, including those in the Lower Keys Region, Back Bay Region, and Halo Zone for the surface waters surrounding Key West and Stock Island, are not impaired for nutrients——that is, that the NNCs and narrative nutrient criteria, as applicable, are being met. Pursuant to sections 403.061 and 403.067, Florida Statutes, and rule 62-303.600, DEP has classified the Florida Keys WBIDs as Category 2 under the waterbody use attainment classification scheme34/ for nutrients and nutrient response. The classification of the Keys WBIDs in this category means that sufficient water quality data are available to determine that at least one designated use is attained. Thus, as authorized by section 403.067 and rule 62-303.600(2), DEP has placed the Keys WBIDs on the "Delist List."35/ This "de-listing" action recognizes that the Florida Keys WBIDs, including those in the Halo Zone, are not impaired for nutrients and chlorophyll-a. Subsurface Geology in Vicinity of Stock Island The parties agree that, as a general proposition, the ground water and surface waters are connected to each other in the Florida Keys. However, no evidence was presented showing a specific location or locations where ground water connects to surface waters. Although it generally is undisputed that, at some point, ground water connects to surface waters, the parties disagree regarding whether, where, and how long it may take for the injected effluent to reach surface waters. Petitioners contend that due to the local geology, the injected effluent from the Existing Wastewater Facility rapidly reaches surface waters in the vicinity of Stock Island and that the increased discharge through the new injection wells will exacerbate and cause or contribute to surface water quality violations in the immediate vicinity of Stock Island and offshore. In support of this position, Petitioners presented the testimony of Scott Zednek, a Florida-licensed P.G. Zednek opined that due to the absence of subsurface sediments that would prevent upward flow to surface waters, the buoyant freshwater effluent injected down the wells will rapidly vertically migrate through the highly transmissive Key Largo Limestone and Miami Limestone to reach surface waters. To develop his opinion, Zednek reviewed a Florida Geological Survey boring log ("FGS Log") approximately one-third mile from the Existing Wastewater Treatment Facility and a Universal Engineering Services geotechnical study boring log ("UES Log") performed on the KWRU site. The FGS Log was prepared specifically to analyze the subsurface geology. The UES Log was performed as part of a geotechnical study to analyze subsurface conditions onsite specifically for the purpose of determining the load-bearing capability of the KWRU site to support a concrete water tank. As such, the FGS Log provides a more precise view of the subsurface geology in the vicinity of the KWRU site.36/ Based on the UES Log, Zednek opined that there are no confining layers underlying the KWRU site. The UES Log for the site shows N-values, generated using an ASTM-designated process for determining the resistivity or strength of the subsurface, of between two and 43 for the first 60 feet of sediment below the surface. According to Zednek, an N-value of less than 50 indicates lack of a confining layer. Further, his review of the UES Log did not show the presence of Q-layers, which may function as semi-confining layers, or aquitards, that would substantially restrict the movement of fluid, including the injected effluent.37/ Based on the UES Log, Zednek opined that the limestone underlying the site is fractured, creating vertical pathways for the injected effluent to migrate upward to the surface. Zednek testified that the Key Largo Limestone, into which the effluent is injected, is very porous and highly transmissive, facilitating rapid migration once the effluent is injected. Based on his review of the FGS Log, Zednek testified that a Q-layer first appears at approximately 62 feet below the ground surface——below the depth of the injection wells' casing—— so it would not act as a confining layer for the injected effluent. Zednek further observed that this Q-layer is only 1.5 centimeters thick. In his experience, this thickness is not sufficient to create a confining or semi-confining layer. Zednek thus opined that the subsurface geology at the KWRU site will enable and facilitate vertical migration of the injected effluent to surface waters. Zednek also noted the proximity of the Safe Harbor channel cut. He opined that the injected effluent likely would horizontally migrate through the highly transmissive Key Largo Limestone,38/ then vertically migrate to surface waters through the "path of least resistance" at the Safe Harbor channel cut. As further support for his opinion, Zednek cited an interim report summarizing results of a subsurface dye tracer study performed for the Florida Keys Aqueduct Authority regional wastewater treatment facility. The study's purpose was to determine whether the subsurface geology at the Cudjoe Key location was sufficiently confining to prevent vertical migration of the injected effluent from shallow injection wells proposed at that facility. According to Zednek, the interim report showed that the subsurface at the injection site was not sufficiently confining to prevent the injected effluent from rapidly vertically migrating to surface waters. Petitioners also presented the testimony of John Paul, Ph.D., in support of their contention that the injected effluent from the Expanded Wastewater Facility would rapidly rise through the subsurface limestone up into surface waters. Dr. Paul testified regarding viral tracer studies he had conducted at Long Key, approximately 65 miles east-northeast of Stock Island, and at the Saddlebunch Keys, located approximately 20 miles east- northeast of Stock Island. In conducting these studies, Paul injected bacteriophage viruses into Class V wells and tracked their movement into surface waters. In the Long Key study, the injected viruses moved through the subsurface limestone to the south-southeast and appeared in surface waters in deep canals on the ocean side of U.S. 1 approximately 53 hours after injection. In the Saddlebunch Keys study, the viruses also appeared in surface waters some distance south-southeast of the location at which they were injected.39/ Paul acknowledged that when the viruses appeared in surface waters, they were detected at a concentration of one trillionth (.0000000000001 or 1 x 10-12) less than the concentration in which they had been injected, indicating significant dilution by ground water and/or surface waters. He also acknowledged that canals dredged to depths shallower than the injected depth may not facilitate rapid migration of the injected effluent to surface waters. In rebuttal, KWRU presented the testimony of Michael Alfieri, a Florida-licensed P.G. who specializes in hydrogeology. Alfieri examined the FGS Log and UES Log, and also reviewed the detailed lithology logs and photographs for the FGS Log. Based on his review of this information, Alfieri opined that the FGS Log indicates the presence of semi-confining layers that function as aquitards in the first 60 feet of subsurface sediment. Alfieri noted that the existence of an aquitard depends on the nature of the geologic materials present at that location, so that N-values do not perfectly correlate with the presence or absence of confining layers. Thus, a carbonate silt or clay having an N-value of only two may better function as an aquitard than a porous, transmissive limestone having an N-value of 50, and silts or clays having a thickness as little as one centimeter may function as an aquitard to significantly impede fluid flow.40/ Based on his review of the FGS Log and the detailed lithology log descriptions and photographs for the FGS Log, Alfieri observed four laminated calcrete zones, six Q-zones, and chalky limestone within the first 60 feet——all of which would function as aquitards to impede the vertical movement of the effluent.41/ Thus, according to Alfieri, the effluent is anticipated to migrate laterally from the injection wells below these confining layers before migrating through a vertical pathway to reach surface waters at an unknown location. To predict the likely migration pathway for the effluent, Alfieri conducted hydrological modeling using a simplistic SEAWAT computer model. He used horizontal and vertical transmissivity values for the subsurface strata derived from geological studies previously conducted in the Florida Keys. Although these studies indicate greater horizontal than vertical transmissivity, Alfieri assumed equal vertical and horizontal transmissivity for modeling purposes——necessarily yielding more conservative results than would be anticipated to occur in real life. Accordingly, the modeling results showed more rapid vertical migration than would be anticipated in real life when the Q-zones and calcrete layers depicted in the FGS Log are considered. Even with these conservative assumptions, the modeling results showed the injected effluent migrating horizontally at least a mile offshore42/ before migrating upward to surface waters. The persuasive evidence shows that the injected effluent will be confined to the subsurface and will travel laterally a substantial distance before rising to surface waters at some unknown location or locations offshore. Thus, the credible, persuasive evidence does not support the conclusion that the effluent will rapidly rise to the surface waters in the nearshore area in the vicinity of the KWRU site.43/ Narrative Nutrient Criteria Petitioners allege that the effluent injected down the wells into the ground water will reach surface waters, causing or contributing to a violation of the narrative nutrient criteria for surface waters codified in rules 62-302.530(47)(a) and (b).44/ In support, Petitioners presented the testimony of James Fourqurean, Ph.D., who has extensive experience in research on Florida Keys aquatic ecosystems in their healthy and imbalanced states. Dr. Fourqurean described these ecosystems in their healthy state and in their nutrient-enriched state. Florida Keys nearshore ecosystems normally are oligotrophic, which means they are nutrient-limited. Thus, they do not normally exhibit high chlorophyll-a levels and microalgae counts. When nutrient levels in the Florida Keys ecosystems increase——whether by increasing the concentration of nutrients in discharges or by increasing the volume of water containing nutrients——primary production, i.e., plant growth, increases. Seagrass communities are phosphorus-limited, so that when these communities are exposed to phosphorus-enriched water, the phosphorus is rapidly absorbed from the water column and is stored in the benthos.45/ This phosphorus capture initially leads to increased seagrass abundance, but as phosphorus enrichment continues, the community species composition rapidly shifts to favoring seaweed and microscopic algae, ultimately damaging or destroying the seagrass community. Coral reef communities similarly are nitrogen-limited. Thus, when coral reef communities are exposed to nitrogen- enriched water, they shift to algae-dominated communities——again, damaging or destroying the coral reef communities. Based on historical aerial photographs of the area surrounding Safe Harbor and his experience studying seagrasses in the Florida Keys, Fourqurean concluded that the natural seagrass populations in the entire Florida Keys National Marine Sanctuary area, which includes the Stock Island area, are experiencing ecological imbalance. On the basis of the water quality sampling he conducted in and around Safe Harbor, Fourqurean opined that the imbalance is the result of man-induced nutrient enrichment. However, he did not engage in field studies in and around Safe Harbor, so could not cite specific examples where seagrasses had been replaced by algal-dominated communities in that area. Fourqurean noted that human waste contains high concentrations of phosphorus and nitrogen. In his view, because the effluent from the Existing Wastewater Facility contains phosphorous, it necessarily constitutes a source of phosphorous in the surface waters in Safe Harbor, even though it is injected into ground water. However, he acknowledged the existence of numerous other sources of nitrogen and phosphorus in the Safe Harbor vicinity, including septic tanks, boat cleaning operations and pump outs, and storm water runoff. He further acknowledged that he did not know where or when effluent from the Existing Wastewater Facility (and, by extension, the Expanded Wastewater Facility) may reach surface waters. Fourqurean acknowledged that the Permit at Issue would authorize the injection of effluent treated to AWT standards into ground water, rather than directly to surface waters, and he further acknowledged that the total phosphorus and nitrogen loading from the Expanded Wastewater Facility would substantially decrease as a result of conversion to AWT, even though the volume of effluent discharged down the wells may as much as double. He remained concerned that the Expanded Wastewater Facility may contribute phosphorus——even in very small quantities——to surface waters, causing imbalance to seagrass communities. He also opined that when saline ground water and the fresher effluent mix, the resulting brackish solution would dissolve the calcium carbonate comprising the subsurface limestone, releasing stored phosphorus that would eventually reach surface waters and negatively affect nearshore seagrass communities, However, he acknowledged that depending on subsurface physical conditions and flow paths of the effluent, phosphorous, nitrogen, or both, may be completely removed prior to the effluent reaching surface waters. He further acknowledged that seagrass community health in the Florida Keys National Marine Sanctuary has improved in the last two years and that water quality also has improved, reversing a ten-year decline. This is consistent with replacement of onsite septic tanks by central wastewater treatment systems in the Florida Keys. On rebuttal, KWRU presented the testimony of William Precht, who has extensive experience with Florida Keys geology and aquatic communities. Precht confirmed the existence of numerous sources of significant nutrient enrichment in the Safe Harbor vicinity other than the Existing Wastewater Facility, and noted that these sources must be taken into account when analyzing nutrient enrichment in Safe Harbor. He testified that raw wastewater is particularly deleterious to benthic communities. Thus, connecting wastewater generators that currently use septic tanks to central wastewater treatment systems can significantly improve water quality. Precht observed that Fourqurean's single-day sampling in the Safe Harbor area provided information regarding variability in nutrient concentrations, but characterized Fourqurean's conclusion that the Existing Wastewater Facility was the source of the nutrients as "unscientific" because it was based on supposition rather than on testing. He opined that the limited data set gathered over a one-day period could not reliably identify the source of nutrient enrichment in Safe Harbor. Precht testified that flushing capability is a key influence on nutrient concentration in surface waters. The further from a natural marine environment that water quality testing is performed, the more likely water quality will be poor due to nutrient enrichment from land-based sources. Given the configuration of Safe Harbor, water quality would be poorest in the interior dead-end canals and would steadily improve as one moved into more open water and flushing increased, with the highest water quality in open waters outside the canal system. Precht opined that the presence of noxious benthic plant life in the Safe Harbor vicinity may be attributable the destruction of seagrass communities in the area by historical dredging, rather than due to nutrient enrichment. Based on the reduction in total nitrogen and total phosphorus loading as a result of implementing AWT, Precht opined that the proposed discharge will not negatively affect the biological communities in the Safe Harbor vicinity. He further opined that due to the rapid uptake of phosphorus in the marine environment and due to denitrification that occurs in ground water and in marine surface waters, there is little chance that any nutrient loading that may result from the injected effluent would cause damage to the coral reef environment. Also on rebuttal, Alfieri persuasively testified that although phosphate release does occur when freshwater is injected into limestone that formed in a saline environment, this process gradually occurs over "geologic time"——that is, over millions of years. Therefore, he did not anticipate a significant release of phosphate from the subsurface limestone as a result of the effluent discharge. Also, limestone rapidly absorbs phosphorous, so phosphorus in the injected effluent would be absorbed quickly by the subsurface limestone.46/ Further, in any event, the effluent will be diluted by at least seven orders of magnitude——that is, one hundred millionth (.00000001)——of the injected concentration by the ground water, and/or by surface waters (assuming the effluent eventually reaches surface waters). As discussed above, the Keys RAP was prepared in 2008 and updated in 2011. The Keys RAP prescribes specific management activities to be implemented to restore surface water quality in the Florida Keys, including eliminating cesspits and onsite septic tank systems and connecting wastewater generators to centralized wastewater systems that treat the wastewater to AWT standards. Pursuant to the Impaired Waters Rule and DEP's adoption of the Keys RAP, activities that are consistent with the Keys RAP are considered to provide reasonable assurance that the narrative nutrient criterion in rule 62-302.530(47)(b) will be met. As discussed above, the Project will expand a centralized wastewater treatment plant that will accept, and treat to AWT standards, wastewater generated by development on Stock Island——including development that currently relies on onsite septic tanks for wastewater disposal. The Project is consistent with the Keys RAP, so there is reasonable assurance that the Project will meet the narrative nutrient criterion in rule 62-302.530(47)(b). The persuasive evidence shows that the Project will not cause or contribute to alterations of nutrient concentrations in water bodies so as to cause an imbalance in natural populations of aquatic flora or fauna. Thus, Petitioners failed to show that the Project will cause or contribute to violation of the narrative nutrient criterion in rule 62-302.530(47)(b). Further, for the reasons discussed below, it also is determined that the Project will not violate the narrative nutrient criterion codified at rule 62-302.530(47)(a). Numeric Nutrient Criteria Petitioners also allege that the effluent will cause or contribute to violation of the estuary-specific numeric interpretations of the narrative nutrient criteria for the Back Bay nutrient region, codified at rule 62-302.532(1)(g)1., and the Lower Keys nutrient region, codified at rule 62-302.532(1)(g)3. In support, Petitioners cite the results of surface water sampling performed by Fourqurean in the Safe Harbor area showing high levels of nitrogen, phosphorus, and chlorophyll-a. Petitioners contend that these high nutrient levels evidence that the existing injection wells already are causing or contributing to surface water quality violations in the waters surrounding Stock Island, and that the increased effluent discharge from the proposed new injection wells will exacerbate this situation, further causing or contributing to violations of surface water quality standards. In preparing his opinion regarding the effect of the proposed injection wells on surface water quality, Fourqurean sampled surface water quality on one day at nine stations located in the vicinity of Stock Island, ranging from shallow waters inside the Safe Harbor basin to deeper waters offshore. Samples were collected at the surface and at a depth of one meter below the surface following the standard operating procedures for water quality sampling established by the Florida Keys Water Quality Protection Program. Fourqurean testified that the samples collected at the stations inside the Safe Harbor basin and near the shore of Stock Island showed very high levels of chlorophyll-a, evidencing that these areas are dominated by microalgae and, thus, are eutrophic. Additionally, the samples collected inside the Safe Harbor basin exhibited very high phosphorus concentrations—— almost three times greater than the estuary-specific numeric nutrient criterion for phosphorus. Phosphorus concentrations correspondingly decreased as samples were collected outside of the basin and offshore. Nitrogen concentrations followed a similar pattern in the sampling that Fourqurean conducted inside and outside of the Safe Harbor basin. According to Fourqurean, the high nutrient concentrations in the samples taken in Safe Harbor, when compared to the lower concentrations in samples taken outside of Safe Harbor, evidence the existence of a large source of phosphorous and nitrogen in Safe Harbor——in his view, the Existing Wastewater Facility. However, Fourqurean acknowledged that there are many potential nutrient enrichment sources on Stock Island, including fishing operations, boat sewage pump-outs, and direct discharges of storm water to surface waters. He further acknowledged that the specific source of phosphorus and nitrogen in the surface waters surrounding Stock Island cannot be identified. He did not opine as to the relative amounts of nutrients in surface waters that he believes are being contributed by the Existing Wastewater Facility or that will be contributed by the Expanded Wastewater Facility, as compared to other nutrient sources in the Safe Harbor area. He also acknowledged that a scientifically-valid water quality study would require more than a single day of sampling.47/ Kenneth Weaver, environmental administrator for DEP's Standards Development Section,48/ credibly and persuasively testified, and the water quality data for nutrients and chlorophyll-a collected in the WBIDs surrounding Key West and Stock Island show, that the surface waters in these WBIDs meet the applicable NNCs.49/ Historical water quality data also show that since 2008, the surface waters in these WBIDs continuously have met the baseline concentrations on which the NNCs were established and adopted. Even with the increased volume of wastewater treated by the Expanded Wastewater Facility, implementation of the AWT standard by the facility's wastewater treatment trains will substantially reduce the amount of total nitrogen and total phosphorus discharged into ground water through the injection wells. Specifically, for total nitrogen, the concentration will be reduced from 13.92 mg/L to 2.25 mg/L, and the total amount of nitrogen loading will be reduced from 58 to 15.9 pounds per day, representing a total net reduction of 72.4 percent in the discharge of total nitrogen. For total phosphorus, the concentration will be reduced from 3.47 mg/L to .75 mg/L, and the total amount of phosphorus loading will be reduced from 14.4 to 5.3 pounds per day, representing a total net reduction of 63.3 percent in the discharge of total phosphorus.50/ Weaver addressed the effects of these projected nutrient discharge concentrations on the surface waters in WBIDs 8074 and 8079, which comprise the portions of the Lower Keys Region and Back Bay Region closest to the KWRU site. He opined that, because these regions are currently meeting the applicable NNCs for nitrogen and phosphorus, and because KWRU's implementation of AWT will result in substantial reduction of total nitrogen and phosphorus loading, the NNCs will continue to be met in these regions——even in a "worst-case" scenario that assumes all of the treated effluent from the Expanded Wastewater Facility is disposed of through the injection wells and reaches the surface. The persuasive evidence shows that the Project will not cause or contribute to violations of the applicable numeric nutrient criteria. Thus, Petitioners failed to show that the Project will cause or contribute to violation of the applicable numeric nutrient criteria in rule 62-302.532(1)(g)1. and 3. Surface Water "Free-From" Standards Petitioners allege that the effluent contains iron and copper above detection limits, as well as personal care products and pharmaceuticals, and that these constituents violate rules 62-302.500(1)(a)5. and 62-302.530(61). Rule 62- 302.500(1)(a)5. requires all surface waters of the state to be free from domestic, industrial, agricultural, or other man- induced non-thermal components of discharges which, alone or in combination with other components of discharges (whether thermal or non-thermal), are present in concentrations which are carcinogenic, mutagenic, or teratogenic to human beings or to significant, locally occurring wildlife or aquatic species, unless specific standards for such components are established by rule. Rule 62-302.530(61) effectively requires surface waters to be free from substances in concentrations which injure, are chronically toxic to, or produce adverse physiological or behavioral response in humans, animals, or plants. These rules collectively comprise the "free-from" standards for surface waters. Petitioners presented no evidence to substantiate the allegation that the effluent from the Expanded Wastewater Facility will contain pharmaceuticals or personal care products. However, even assuming these constituents were present in the effluent, Petitioners did not present evidence showing that they are carcinogenic; mutagenic; or teratogenic to human beings or to significant, locally occurring wildlife or aquatic species; or that they are injurious or chronically toxic to, or produce adverse physiological or behavioral response, in humans, animals, or plants. Petitioners did not present evidence showing that the effluent contains copper and iron in quantities that violate any applicable surface water quality standards, including the surface water "free-from" standards. Paul testified, based on sampling he conducted at domestic wastewater outfalls discharging directly to surface waters, that effluent treated to AWT standards often contains pathogenic bacteria and viruses that constitute threats to human health. On this basis, he opined that even though the effluent from the Expanded Wastewater Facility is treated to AWT, it may contain pathogenic constituents that are harmful to human health. However, as previously discussed, the evidence shows that the effluent discharged through KWRU's injection wells will be substantially diluted by groundwater, and also by surface waters to the extent it reaches surface waters at some unknown location. Accordingly, the results of Paul's pathogen studies cannot be extrapolated to conclude that KWRU's effluent also will contain pathogenic bacteria and viruses in such amounts as to constitute a threat to human health. Petitioners failed to show that the effluent disposed of in the injection wells will cause or contribute to violations of the surface water quality standards in rules 62- 302.500(1)(a)5. and 62-302.530(61). Dilution to Meet Surface Water Quality Standards Petitioners allege that KWRU is relying on dilution of the effluent in order to meet surface water quality standards without having been permitted for a mixing zone, in violation of rule 62-302.500(1)(c).51/ This contention lacks merit. As discussed in detail above, the credible, persuasive evidence establishes that the effluent discharged through the injection wells will not violate water quality standards for and parameters, including for nutrients, and will not cause or contribute to the violation of water quality standards. The credible, persuasive evidence establishes that once injected, the effluent will horizontally migrate a considerable distance before it may migrate vertically to reach surface waters. The parties generally agree that ground water and surface waters are "connected" in the Florida Keys. To that point, although it appears likely that at some point the effluent will reach surface water, the evidence does not establish that is an absolute certainty. Nonetheless, even assuming the effluent would reach surface waters at some unknown location and time, the persuasive evidence shows that it would be so substantially diluted by the ground water that it would neither cause nor contribute to violations of surface water quality standards. Further, the persuasive evidence, consisting of Weaver's "worst case" analysis of nutrient loading from the effluent discharge, which assumed no dilution by ground water, establishes that even if the effluent——which will be treated to AWT standards——were discharged directly into surface waters, it would meet the applicable nutrient criteria. Finally, Petitioners' claim assumes that the effluent will be discharged into surface waters. However, as discussed above and in greater detail below, to the extent the effluent ultimately may be discharged to surface waters, such discharge would be indirect, so would not be subject to statutory and rule provisions requiring establishment of a mixing zone. For these reasons, Petitioners failed to prove that KWRU violated any applicable law or rule by not requesting and obtaining a mixing zone for the discharge of the effluent through the injection wells. Class V Injection Wells in Monroe County Petitioners also allege that issuance of the Permit at Issue violates rule 62-528.630(7), which requires all Class V Group 3 domestic wastewater injection wells in Monroe County to provide reasonable assurance that operation of the well will not cause or contribute to a violation of surface waters standards as defined in chapter 62-302. As discussed above, the credible, persuasive evidence establishes that the operation of the wells as authorized under the Permit at Issue will not cause or contribute to violations of surface water quality standards codified in chapter 62-302. Accordingly, Petitioners failed to prove that the Permit at Issue should be denied on the basis that it violates rule 62-528.630(7). Antidegradation Petitioners contend that the Permit at Issue must be denied because KWRU failed to provide reasonable assurance that the injection of effluent will not violate the antidegradation requirements applicable to surface waters codified at rules 62- 4.242, 62-302.300, 62-302.530(47)(a), and 62-302.700(1). This contention lacks merit. As more fully discussed below, the antidegradation requirements in these rules apply only to a direct discharge to surface waters, which is not present in this case. Here, the evidence clearly establishes that the injection wells do not directly discharge effluent into surface waters. It is undisputed that the effluent will be injected from the wells into Class III ground water, where it will migrate through the subsurface strata. Although it is likely that, due to a "connection" between ground water and surface waters, the effluent ultimately will reach surface waters at some unknown location or locations at some unknown time, this constitutes an indirect discharge, which is specifically excluded from the term "discharge of a pollutant." Fla. Admin. Code R. 62-620.200(13). However, even if the antidegradation rules did apply to the discharge of the effluent through the injection wells, Petitioners failed to prove that the discharge would degrade surface waters. As discussed above, the credible, persuasive evidence establishes that the surface waters in the Florida Keys, including those in and around Stock Island and Key West, currently meet the narrative and/or nutrient criteria, as applicable, and that effluent discharged through the injection wells will be treated to AWT standards, substantially reducing the facility's total nutrient loading below current levels. Thus, the credible, persuasive evidence established that, even in a "worst-case" scenario, which assumes no dilution of the effluent by ground or surface waters, the effluent still would not cause or contribute to a violation of the narrative or numeric nutrient criteria. As discussed above, the credible, persuasive evidence showed that, in fact, the effluent will be very substantially diluted by the ground water into which it is injected, and will be further diluted if and when it ultimately reaches surface waters. For these reasons, Petitioners failed to prove that KWRU did not provide reasonable assurance that the disposal of the effluent through the injection wells would not degrade surface waters, in violation of rules 62-4.242, 62-302.300, 62- 302.530(47)(a), and 62-302.700(1). Alleged Violation of Ground Water Standards Petitioners allege that KWRU did not provide reasonable assurance that the injection wells would not violate applicable ground water standards. Petitioners further allege that there is an underground drinking water source under Stock Island. In that case, more stringent ground water quality and injection well rule standards would apply to operation of the injection wells. Petitioners did not present any credible, persuasive evidence to support these allegations. The persuasive evidence establishes that although there is a fresh water lens under Stock Island, it is not classified as an underground source of drinking water52/ due to its substantial variability in horizontal and vertical extent, which renders the salinity levels highly variable. Thus, the ground water at Stock Island is classified as Class G-III ground water which is non-potable ground water having a total dissolved solids content of 10,000 mg/L or greater, or having a total dissolved solids content of 3,000 to 10,000 mg/L and having been determined to have no reasonable potential as a future source of drinking water or designated by rule as an exempted aquifer. Only the minimum criteria for ground water, known as the "free-from" standards, apply to Class G-III ground water. Fla. Admin. Code R. 62-520.430(1). These criteria require that at all times and in all places, ground water be free from discharge components in concentrations that are carcinogenic, teratogenic, mutagenic, or toxic to humans; acutely toxic within surface waters affected by ground water; pose a serious danger to the public health, safety, or welfare; create or constitute a nuisance; or impair the reasonable and beneficial use of adjacent waters. Fla. Admin. Code R. 62-520.400. There is no evidentiary basis on which to infer that the effluent from Expanded Wastewater Facility that is disposed through the injection wells will violate the free-from standards KWRU's many years of effluent monitoring at the Existing Wastewater Facility show that the effluent does not violate these standards. Further, David Rhodes, a Florida-licensed P.G. employed by DEP, credibly testified that a violation of the free- from standards necessarily would entail the presence of toxic materials in KWRU's effluent and that there would be immediate and dramatic effects on the flora and fauna at the golf course, where reclaimed water is reused for irrigation. Since such effects never have occurred, it is reasonable to infer that the effluent from the Expanded Wastewater Facility will not violate the free-from standards.53/ Additionally, as previously addressed, the credible, persuasive evidence demonstrates that no surface water quality violations will result from installation and operation of the injection wells as part of the Expanded Wastewater Facility. Accordingly, the reasonable and beneficial use of adjacent waters will not be impaired due as a result of the injection wells. Petitioners also claim that due to inadequate treatment by the Expanded Wastewater Facility, the effluent disposed in the injection wells will contain unacceptably high levels of bacteria and viruses. The persuasive evidence establishes that KWRU provides high-level disinfection prior to injecting the effluent or sending the reclaimed water for reuse at the golf course. Historical monitoring data shows that KWRU's effluent complies with applicable microbial standards, and unrebutted evidence consisting of quality-related beach closure data for the Florida Keys, gathered as part of the Department of Health's Healthy Beaches monitoring program, indicates that no beach closings in the Florida Keys ever have been attributed to KWRU's Existing Wastewater Facility. Petitioners did not prove that KWRU failed to provide reasonable assurance that operation of the injection wells authorized as part of the Project will not result in violations of applicable ground water standards. To the contrary, KWRU provided reasonable assurance that the effluent from the Expanded Wastewater Facility disposed in the injection wells authorized as part of the Project will not violate any applicable ground water standards. Alleged Water Quality Violations Due to Reuse System Petitioners allege that KWRU did not provide reasonable assurance that the storage of up to 1 MGD of reclaimed water in the reuse system storage ponds on the Key West Golf Club golf course will not cause or contribute to a violation of surface water quality standards and ground water standards. Specifically, Petitioners posit that, because the ponds are unlined, reclaimed water from the Expanded Wastewater Facility will leach from the ponds into the ground water and reach surface waters, violating surface water quality standards and ground water standards and negatively impacting human health through high levels of microbial pathogens, pharmaceuticals, and personal care products. Petitioners further allege that discharge of reclaimed water from the ponds into the ground water could mobilize constituents of concern from the Key West Landfill and a closed waste-to-energy facility, both of which are near the golf course, ultimately resulting in surface water quality standards and ground water violations. In support of these contentions, Petitioners presented the testimony of Scott Zednek, who testified that the reclaimed water, which is fresher than the surrounding ground water, may leach from the ponds into the ground water, and thereafter potentially may reach surface waters. According to Zednek, this leaching could occur because the ponds are unlined. Additionally, Zednek opined that, because there is a closed landfill near the golf course, the reclaimed water leaching from the reuse system ponds could mobilize and spread contaminants from the landfill. The persuasive evidence demonstrates that storage of the reclaimed water in the reuse system ponds will not result in violations of ground water standards or surface water quality standards. Although the golf course ponds are unlined in the sense that a high-density polyethylene or impermeable clay liner has not been installed on the bottom and sides of the ponds, over the years, marl has formed on the bottom and sides of the ponds, creating an aquitard that substantially confines the reclaimed water to the ponds, rather than allowing it to readily leach into the ground water. Further, the reclaimed water generally is less saline than the ground water underlying the course, so tends to "float" on top of, rather than readily mixing with, the denser, more saline ground water. Additionally, the evidence shows that years of historical ground water monitoring data obtained through monitoring wells on the golf course near the reuse system ponds showed no ground water standards violations as a result of storing reclaimed water from KWRU in the ponds.54/ Because the amount of reclaimed water being sent to the reuse storage ponds is not being changed by the Project, and the nutrient levels in the reclaimed water are being through AWT, there is no factual basis from which to infer that storage of the reclaimed water in the pond will result in violations of ground water standards or surface water quality standards. The persuasive evidence also does not support Zednek's view that reclaimed water leaching into the ground water from the storage ponds will mobilize pollutants under the nearby landfill. As discussed above, the persuasive evidence establishes that, due to the aquitard, there will be very little leaching of reclaimed water into the ground water, and even if such leaching did occur, there would be very little mixing of the reclaimed water with the more saline ground water. As such, there is no demonstrated factual basis on which to infer that reclaimed water will flow under, and mobilize and spread pollutants from, the landfill. Further, the evidence establishes that the predominant ground water flow direction under Stock Island is to the south- southeast. Since the landfill is located north of the reuse system ponds, any reclaimed water that did enter ground water would flow south-southeast, away from the landfill. Zednek also opined that if the storage ponds overflowed, the reclaimed water could run off into surface waters, resulting in surface water quality violations. However, the evidence establishes that KWRU will only send as much reclaimed water to the reuse storage ponds as the Key West Golf Club requests, so any assertion that the ponds will overflow is speculative. Further, even if the ponds were to overflow, Petitioners did not show that the reclaimed water would flow into surface waters, or that it would violate surface water quality standards if it were to flow into surface waters. Petitioners did not prove that KWRU failed to provide reasonable assurance that the storage of reclaimed water in the reuse system storage ponds at the Key West Golf Club will not violate any ground water standards. Stated another way, KWRU provided reasonable assurance that the storage of reclaimed water in the reuse system ponds at the Key West Golf Club golf course will not cause or contribute to violations of ground water standards or surface water quality standards. Applicability of AWT to Existing Wastewater Facility Commencing January 1, 2016, the two new treatment trains authorized by the Permit at Issue must meet the AWT standards. These treatment trains are authorized to treat wastewater to specified secondary standards through December 31, 2015. Petitioners assert that the Permit at Issue must be denied because the two new treatment trains should be required to meet AWT standards immediately upon operation, and that allowing the new treatment trains to meet secondary standards through December 31, 2015, violates section 403.806(10) and rule 62- 620.620(4). Sections 403.086(10)(c) and (d) expressly impose the AWT standards on all new or expanded domestic wastewater discharges after December 31, 2015. Accordingly, the Permit at Issue is completely consistent with the statute. Further, the Permit at Issue does not violate rule 62- 620.602(4). That rule requires a wastewater facility permit applicant to make certain specified demonstrations when a permit is renewed, revised, or reissued having a less stringent effluent limitation than contained in a previous permit. Although the Existing Permit states that the Existing Wastewater Facility has been modified to meet the AWT standards, it further states: "[t]he extended aeration process will be switched to the AWT nutrient removal system prior to January 1, 2016." The clear import of this statement is that the AWT standards are not required to be met until January 1, 2016, consistent with section 403.806(10). Because the Permit at Issue also requires the new treatment trains to meet the AWT standards commencing on January 1, 2016, the Permit at Issue does not impose a less stringent effluent limitation than that imposed by the Existing Permit; accordingly, KWRU is not required to make the so-called "anti-backsliding" demonstrations set forth in rule 62- 620.620(4). Furthermore, it is undisputed that the new treatment trains will not be constructed and operational before January 1, 2016; thus, as a practical matter, the new treatment trains must meet the AWT standards immediately upon going into operation. Thus, Petitioners have not shown that the Permit at Issue should be denied on the basis that it violates section 403.806(10) and rule 62-620.620(4). Petitioners' Standing As noted above, Petitioner Halloran, resides in Key West, Florida. His residence fronts on the water and he owns a boat. Halloran and his family use and enjoy the waters around Key West for swimming, fishing, kayaking, and other in-water recreational uses, eat local-caught seafood, and engage in nature photography. Halloran also owns rental properties that front on the water, and he owns and rents out dock space for houseboat mooring. He is a member of Last Stand. Halloran has challenged the Permit at Issue because he is concerned that the increased discharge of effluent from the Project down the injection wells will degrade the waters around Key West where he and his family engage in in-water recreational uses. He also is concerned that the increased effluent discharge, particularly nutrients, will harm the seagrasses, coral reefs, and the benthic communities in the waters around Key West. Halloran read the initial petition prepared and filed in this proceeding, and he skimmed the Amended Petition specifically to determine the changes from the initial Petition.55/ He acknowledges that he does not completely recall the entire contents of the initial petition or the Amended Petition. Petitioner Last Stand is a not-for-profit corporation incorporated under Florida law. Naja Girard D'Albissin, a member of the Board of Directors of Last Stand, appeared on behalf of Last Stand. D'Albissin testified that Last Stand currently has approximately 105 members. Last Stand's mission is to promote, preserve, and protect the quality of life in Key West and the Florida Keys, with particular emphasis on protecting the natural environment. Last Stand historically has engaged in environmental advocacy directed toward governmental entities and engaged in litigation opposing activities that its members believe would harm the natural environment. In July 2014, Last Stand's Board of Directors voted to challenge the Permit at Issue. Respondent DEP stipulated that 52 members of Last Stand spend time or reside in Monroe County, 50 members enjoy the waters and natural environment of the Florida Keys, and 50 members believe that their use and enjoyment of the natural environment and economic interests in Monroe County will be adversely affected by the Project. Last Stand tendered, for admission into evidence, affidavits of some of its members attesting to the substantial interests they contend will be injured by the Project. However, Last Stand had refused to allow Respondents to engage in discovery regarding these members' alleged substantial interests; accordingly, the undersigned did not allow these members to testify at the final hearing.56/ The affidavits were excluded from admission into evidence as unsupported hearsay. See § 120.57(1)(c), Fla. Stat. Entitlement to Permit at Issue KWRU met its burden under section 120.569(2)(p) to present a prima facie case demonstrating entitlement to the Permit at Issue by entering into evidence the applications and supporting materials for the Permit at Issue for the Project. Additionally, KWRU presented persuasive, competent, and substantial evidence beyond that necessary to meet its burden under section 120.569(2)(p) to demonstrate its entitlement to the Permit at Issue. Petitioners did not meet their burden of persuasion under section 120.569(2)(p) in this proceeding to demonstrate that the Project does not meet all applicable statutory and rule requirements. Furthermore, on rebuttal, KWRU and DEP thoroughly addressed and rebutted the grounds that Petitioners allege justify denial of the Permit at Issue. The persuasive evidence demonstrates that the Project meets all applicable statutory and rule requirements. Accordingly, KWRU is entitled to issuance of the Permit at Issue.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Protection enter a final order approving the issuance of Domestic Wastewater Facility Permit FLA014951-012-DWIP and UIC Permits 18490-020 and 18490-021.

Findings Of Fact J. Armand Martin is the owner of a lot located in Pasco County, Florida, which includes an island surrounded by a body of water known as Sleepy Lagoon and a 15-foot strip of land on the mainland. This case arose out of Martin's efforts to develop this lot and construct a personal residence on the island. Residential dwellings surround the lagoon and Martin's island. In order to build a residence on the island, Martin had to install a septic tank. To install a septic tank Martin had to apply for a permit to install an individual sewage disposal system. It was Martin's original intent to locate the sewage treatment facility on the mainland and pipe the sewage over the bridge he planned to build to access his island. Martin made application for the required septic tank permit to the Pasco County Health Department. The inspector from the Pasco County Health Department was taken aback by the situation she encountered when she did the preliminary inspection and called in her supervisor, Donald Van Kampers, for assistance. Van Kampers eventually inspected the island and suggested that Martin put his individual sewage disposal system on the island itself, pointing out that because the island was so low the installation would probably have to include a sand filter system and possibly a chlorinating system. Van Kampers also advised Martin that he would have to seek a variance from the Staff Director of the Health Program Office pursuant to Rule 10D-6.21, Florida Administrative Code, because the island was so narrow that the system would be within 50 feet of the lagoon's waters contrary to Rule 10D-6.24(4), Florida Administrative Code. Martin received assistance from Van Kampers on his application for the variance. This application called for the filing of a site plan drawn to scale. In addition to being surrounded by Sleepy Lagoon, Martin's island circumscribes a small body of water variously referred to as a pond, lagoon and even "wetlands." Martin transmitted to Van Kampers a surveyor's drawing of his island which did not show the island's own small body of water. In an effort to assist Martin, Van Kampers filled in the proposed location of Martin's house and the individual sewage disposal system (septic tank with sand filter) on this surveyor's drawing, attached it to Martin's request for a variance and forwarded it to the Staff Director for the Health Program Office together with a recommendation of approval by the Pasco County Health Unit. This drawing did not show the body of water on the island. The Staff Director forwarded the application to the Review Committee which he appoints to review applications for variances. There is no evidence that Martin saw this drawing prior to the Review Committee's approval of the variance which, with the affirmative recommendation of the Pasco County Health Unit, was summarily granted. Subsequently, several of the residents surrounding Sleepy Lagoon and Martin's island became concerned about the potential problems which Martin's individual sewage disposal system would have on their lagoon, its environment and its ecology. Their complaints eventually came to the attention of the Staff Director of the Health Program Office, who in turn forwarded the matter to John Heber, the Department's representative to the Review Committee, for investigation. Heber conducted a personal inspection of Martin's island and compared it with the drawing filed by Van Kampers in Martin's behalf. Heber found that according to the drawing the individual sewage disposal system would be located in the middle of the water on Martin's island. Having made this discovery, Heber initiated actions which resulted in the Issuance of an Administrative Complaint to have the variance issued Martin rescinded. The Administrative Complaint alleged that Martin had "misrepresented" facts on his application for the variance by not showing the water on his island. Martin made a timely request for a formal hearing on the allegations. Martin did not fill out the drawing which accompanied his application. It was filled out by Van Kampers, who did not draw in the island's water and put the individual sewage disposal system in the middle of where the water is currently located. Van Kampers and his supervisor, both of whom visited the island, did not consider the water on the island subject to the rules which call for the reporting of lakes, streams or canals. See Rule 10D-6.23(2)(a), Florida Administrative Code. In regard to their classifications of surface waters, they are the officials charged under the regulatory scheme with determining when applicants must seek a variance. Applicants must seek a variance when, like Martin, their septic tanks are too close to certain surface waters. See Rule 10D-6.24(4), Florida Administrative Code. Clearly, they determine when a permit will be issued, when an applicant is required to seek a variance, and what waters must be reported on the scale drawing. In the instant case they classified Sleepy Lagoon as protected waters requiring Martin to seek a variance and the water on the is land as unprotected waters not requiring their inclusion on the drawing, because they determined the water was not a lake, stream or canal. The facts show that this water is not a lake, stream or canal. Under the Department's policy a sewage system can only be constructed as drawn and presented in the application for a variance. If the system in question were constructed, it would require the filling of the area where the water is located. The drawing accurately reflects the post-construction situation with the water not shown.
Recommendation The foregoing Findings of Fact and Conclusions of Law show J. Armand Martin did not misrepresent his application; therefore, the facts of the allegation are not proven, and the variance should not be revoked. DONE and ORDERED this 3rd day of April, 1981, in Tallahassee, Leon County, Florida. STEPHEN F. DEAN, Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32301 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 3rd day of April, 1981. COPIES FURNISHED: Barbara Dell McPherson, Esquire Department of HRS 2255 East Bay Drive Post Office Box 5046 Clearwater, Florida 33518 Mr. J.

Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant findings of fact are made: The Tamaron wastewater treatment facility (facility), located at 3800 Gatewood Drive, Sarasota, Florida, serves the Tamaron residential subdivision which was originally developed by U. S. Homes Corporation in 1976. The subdivision presently consists of 499 homes and was completely built out in the mid-1980's. The facility was originally owned and operated by U. S. Homes Corporation. Tamaron Utilities, a nonprofit entity comprised of the 499 homeowners, acquired the facility in November, 1987. At that time, the facility's existing operating permit was transferred to Tamaron Utilities. The facility is overseen by an elected board of volunteer homeowners. The Department is the agency of the State of Florida that is authorized to regulate domestic wastewater treatment and disposal facilities and permit their construction and operation. It is the successor agency to the Department of Environmental Regulation. By letter dated November 10, 1987, the Department notified Tamaron of the requirements of Chapter 87-303, Laws of Florida (Grizzle-Figg Amendment), which amended Section 403.086, Florida Statutes, and of the Department's intention to modify Tamaron's operating permit to incorporate a schedule of compliance with Section 403.086, Florida Statutes, as amended by Chapter 87-303, Laws of Florida. On August 23, 1988, an operating permit (D058-141783), which contained secondary water treatment requirements, was issued to the facility. Specific condition 7 of the permit required that the facility be in compliance with the Grizzle-Figg Amendment by October, 1990, or eliminate discharge to surface waters. On September 5, 1990, Tamaron filed an application with the Department to renew its domestic waste water treatment and disposal systems operation permit. Tamaron did not consider its facility as discharging waste into one of the specifically named water bodies set forth in the Grizzle-Figg Amendment or to "water tributary thereto" and thereby required to meet the advanced waste treatment criteria set forth in the Grizzle-Figg Amendment. However, in an abundance of caution, Tamaron proceeded to bring its facility into compliance with the advanced waste treatment criteria as set forth in the Grizzle-Figg Amendment. After numerous requests for additional information and several meetings between Tamaron and the Department, the Department issued its Notice of Permit Denial on April 9, 1991, asserting that Tamaron had not provided: (a) reasonable assurance that the requirements of Section 403.086(1)(c), Florida Statutes, mandating advanced waste treatment (AWT) before discharge to certain designated surface waters, would be met and; (b) reasonable assurance that the discharge to those certain designated surface waters would result in minimal negative impact as required by Section 403.086(5)(a), Florida Statutes. The facility continues to operate under its secondary treatment permit No. DO58-141783. The facility consists of a wastewater treatment plant designed for secondary treatment, with tertiary filtration. The design capacity of the facility is 155,000 gallons per day (0.155MGD) with actual flows of slightly over 100,000 gallons per day (0.100MGD+). Three percolation ponds surround the facility comprising the primary effluent disposal method for the facility. The Tamaron subdivision has a series of excavated surface water bodies (stormwater lakes), hydraulically connected, which eventually discharge at the northeast corner of the subdivision into Phillippi Creek. The direct path of surface water flow is from the subdivision's stormwater lakes to Phillippi Creek. These stormwater lakes are in multiple ownership. Under Department policy, stormwater systems permitted by the Department, its predecessor DER, or a water management district solely as stormwater treatment facilities under Chapter 17-25, Florida Administrative Code, are not considered "waters of the State". However, stormwater systems built prior to Chapter 17-25, Florida Administrative Code, permitting requirements, were considered "waters of the State" if they discharge more frequently than a twenty five year, twenty-four hour storm event. See Petitioner's exhibits 13 & 15. Tamaron's stormwater system was built prior to Chapter 17-25, Florida Administrative Code, permitting requirements, and was designed to discharge at a ten year, twenty-four hour storm event which is more frequent than a twenty five year, twenty-four hour storm event. Discharge of water into Phillippi Creek from the subdivision's stormwater lakes is fairly frequent; however, the volume of the discharge is low. Phillippi Creek is a natural surface water which eventually flows into Roberts Bay. Roberts Bay is a specifically named water body in the Grizzle-Figg Amendment (Section 403.086(1)(c), Florida Statutes). Since September, 1989, Tamaron has retained William Murchie, P.E. of AM Engineering, to evaluate the design and operation of the facility in order to comply with appropriate regulatory requirements. The facility provides biological treatment through a contact stabilization utilizing an activated sludge. This process typically provides high quality advanced secondary biological treatment. A chemical feed tank system utilizing ferrous sulfate was added to the facility several years ago to chemically precipitate out total phosphorus to meet the advanced waste treatment requirements. High-level disinfection is achieved in the large chlorine contact chamber and through two tertiary filters. At the design flow of 0.155MGD, the chlorine contact chamber provides nearly 80 minutes of contact time, while actual contact time for existing flows, not including time in filters, is calculated at 110 minutes. Upon leaving the chlorine contact chamber and the biological treatment components of the facility, the chlorinated effluent is directed through two tertiary filters to reduce the biochemical oxygen demand (BOD) and total suspended solids (TSS). After the tertiary filters, the effluent passes through the sample block where it is sampled for TSS, BOD and chlorine and is then piped sequentially into the first, second and third percolation ponds. The percolation ponds span two acres and provide residence time of 35 to 45 days, during which time the effluent is further biologically treated and nitrogen is reduced. From the percolation ponds, the effluent is pumped into a low pressure system which uniformly distributes effluent over two nitrogen reduction filters. The nitrogen reduction filters are located north of the plant and are immediately adjacent to one of the subdivision's stormwater lakes. The nitrogen reduction filters consist of deep sand beds covered with Bermuda grass to provide high nitrogen uptake. The irrigation of the two nitrogen reduction filters is alternated every half day. These nitrogen reduction systems were modified in October/November, 1990, by adding 3 to 3 1/2 feet of clean sand with a permeability rate of 28 feet per day, planting Bermuda grass, and installing an irrigation/distribution system. These filters replaced two sand pits with shallow layers of very coarse sand, after initial testing demonstrated the sand pits to be inadequate in removing nutrients consistent with statutory requirements. In January, 1992, an underdrain system utilizing perforated pipe was installed in the nitrogen reduction filters to create an aerobic zone and to provide a representative sample port after nutrient reduction in the filters. This sample port, used for the biweekly monitoring, consists of a single solid pipe, that collects effluent from the perforated pipes, with a tap to prevent discharge into the adjacent stormwater lake, except during sampling events. The biweekly sampling event results in effluent being discharged from the pipe for approximately 30 minutes to flush the pipe so as to get a proper sample. The underdrain sampling port at the nitrogen reduction filters replaced two earlier monitor wells between the nitrogen reduction filter and the stormwater pond, which proved ineffective because of their location. The perforated underdrains are situated in filter bed sand of medium grain size with a permeability rate 100 feet per day and located below 3 - 3 1/2 feet of clean sand with a permeability rate of 28 feet per day and above very permeable layers of sand, stone and coarse shell. (See Tamaron's exhibit 23 and Department's exhibit 14) The very permeable layers of sand, coarse shell, the perforated pipe and the single solid pipe are all located above the ground water table. Since the perforated pipe and sample port are both located above the ground water level and the surface of the adjacent stormwater lake, it is unlikely that the effluent sample taken from the sample port would be influenced by the ground water or a back flow of water from the adjacent stormwater lake. The coarse shell layer situated below the nitrogen reduction filters extends to the edge of the adjacent stormwater lake. Therefore, the effluent, other than the effluent trapped in the perforated pipe and carried to the sample port, that is irrigated onto the nitrogen reduction filters passes through the sand and into the coarse shell layer. The effluent is then transported laterally through the coarse shell layer to the underground edge of the adjacent stormwater lake where there is a subsurface discharge into the adjacent stormwater lake. Since the discharge to the stormwater lakes is primarily subsurface in nature, the logical compliance point to measure effluent parameters would be the underground sample port which collects the effluent prior to subsurface discharge into the stormwater lake. See Petitioner's exhibit 15. The direction of ground water flow at the facility is towards the north to the adjacent stormwater lakes as evidenced by the hydraulic gradient of the site determined using ground water table elevations. The location for sampling effluent from the facility for compliance with secondary standards was described in Specific Condition 5 of Tamaron's previous permit No. D058-141783 dated August 23, 1988. Specific Condition 5 states that the discharge from the chlorine contact chamber shall be sampled in accordance with Chapter 17-19, Florida Administrative Code, (now Chapter 17-601, Florida Administrative Code), for compliance with the stated secondary limits. The facility's tertiary filters are located after the chlorine contact chamber. Tamaron samples effluent for compliance with secondary standards (BOD,TSS, chlorine) at the sampling box after disinfection and tertiary filtration. Tertiary filtration is designed to achieve a more efficient removal of TSS and BOD. The resulting effluent is usually of higher quality than secondarily treated effluent. A secondary plant with tertiary filtration is referred to as an "advanced secondary treatment" plant. Data presented by Tamaron titled Tamaron 1991-1993 Data On FDER Permit Compliance (Tamaron's exhibit 17, page 1 of 2) shows reported values, sampled after tertiary filtration at the sample box, which suggest that secondary treatment parameters, including fecal coliform, are not being exceeded. The data actually shows a very high removal rate for the parameters sampled. The United States Environmental Protection Agency issued a National Pollutant Discharge Elimination System (NPDES) permit, number FL0042811, to Tamaron for the facility with an effective date of June 1, 1991, which authorized Tamaron to discharge from the facility to the receiving waters named Phillippi Creek to Roberts Bay in accordance with the effluent limitation, monitoring requirements and other conditions set forth in the permit. Since the facility was located in the Grizzle-Figg Amendment area of Florida certain changes were made from the draft permit to the final permit. Those changes appear in the Amendment To The Statement Of Basis At The Time Of Final Permit Issuance which is made a part of the final permit. The amendment provides for changes in Part I, Effluent Limitations and Monitoring Requirements. These changes, among other things, require that the Grizzle-Figg Amendment annual limits of 5 mg/l BOD, 5mg/l TSS, 3mg/l total nitrogen and 1mg/l total phosphorus be added to the effluent limits to adequately maintain water quality standards, and added monitoring requirements and measurement frequency regulations to give the basis for permit limits and conditions in accordance with Chapters 17-302, 17-600 and 17-601, Florida Administrative Code. Data presented by Tamaron titled Tamaron 1991-1993 Data On NPDES Permit Compliance (Tamaron's exhibit 17, page 2 of 2) show reported values sampled after nitrogen reduction filters which suggest that the maximum values for AWT parameters, including fecal coliform, are not being exceeded, particularly after January, 1992, when Tamaron began sampling effluent collected by the perforated underdrains at the sample port. Tamaron has been monitoring and reporting compliance under its final NPDES permit and providing copies to the Department. There was no evidence that Tamaron was ever in violation of its NPDES permit. Tamaron submitted documentation to the Department with its permit application that demonstrated high-level disinfection within the facility was being achieved. However, TSS was being sampled after the application of the disinfectant. Using this procedure, the facility continued to achieve high- level disinfection until the permit denial. After the permit denial, the facility resumed basic disinfection which was required under Tamaron's permit for secondary treatment. This same data indicates that there was compliance with the requirements for fecal coliform. The record is not clear as to the frequency and number of samples taken to provide the data for reporting compliance with the NPDES permit and the data presented in Petitioner's exhibit 17, page 2 of 2. However, there was no evidence, other than sampling for TSS after the disinfectant was added, that Tamaron was not complying with its NPDES Permit that required, among other things, that the monitoring requirements and measurement frequency of the Department's rules and regulations be followed by Tamaron. Tamaron has modified and upgraded the facility in order to achieve a treatment process which will produce effluent of a quality for discharge under the Grizzle-Figg Amendment. Tamaron has provided reasonable assurances, although not absolute assurance, that the facility can comply with the discharge permit requirements of Chapter 403, Florida Statutes, including Section 403.086, Florida Statutes, notwithstanding the testimony of Jay Thabaraj to the contrary concerning Tamaron's sampling technique and its method of obtaining high-level disinfection which can be addressed as a specific condition, if necessary. Studies conducted by the Tamaron's engineer included in Petitioner's exhibit 21 indicates that there was no adverse impact to the stormwater lakes from the facility's wastewater treatment and disposal system. Tamaron has provided reasonable assurances that the point of discharge is a reasonably access point, where such discharge results only in minimal negative impact.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Department enter a final order granting Tamaron an operating permit for its facility as secondary treatment facility. In the alternative, that the Department enter a final order granting Tamaron an operating permit for its facility that requires compliance with the advanced waste treatment criteria set forth in Section 403.086(4), Florida Statutes, that, in addition to any general or specific conditions that are normally required, contains specific conditions that: (a) contains specific instructions on sampling technique, sampling frequency and reporting as set forth in Rule 17- 740(1)(b)2., Florida Administrative Code, and (b) sets forth compliance with high-level disinfection, with a time limit for compliance, that accomplishes the intent of the rule, if not the strict letter of the rule, without total redesign of the facility.

Findings Of Fact Petitioner's application for a Class B waste water treatment plant operator was received by Respondent on September 20, 1991. Ms. Setchfield who is in charge of reviewing and approving and/or denying all applications, reviewed Petitioner's application. Based on the documentary evidence submitted by Petitioner, he was given constructive credit for 58 months and actual credits received was 27.6 months for a total credit time of 85.6 months. To receive credit for educational experience, an applicant must demonstrate that his major area of study is in science or biology. Alternatively, an applicant may receive credit provided he furnish Respondent a transcript which would delineate the areas of his studies he successfully completed and the credits received. However, in such instances, an applicant only receives partial credit. Petitioner has been advised (by Respondent) that if he furnish a copy of his transcript, it will be reviewed and if it demonstrates that he is entitled to credit for courses he successfully completed, he would be awarded such credit. Petitioner steadfastly refuses to provide a transcript to Respondent. To be eligible for certification as a Class B waste water treatment plant operator, an applicant must demonstrate, at minimum, that he/she has the required minimum of 96 months total creditable time.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that: Respondent enter a Final Order denying Petitioner's application for certification as a Class B waste water treatment plant operator, as he has failed to satisfy the minimum total time requirement for such certification. 1/ DONE and ENTERED this 29th Tallahassee, Leon County, Florida. day of May, 1992, in JAMES E. BRADWELL Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904)488-9675 Filed with the Clerk of the Division of Administrative Hearings this 29th day of May, 1992.
The Issue Whether, under the facts and circumstances of this case, Respondent's license to practice engineering in the State of Florida, should be revoked, suspended, or otherwise disciplined.
Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant facts are found: At all times material to this proceeding, Respondent, L. Thomas Hubbard d/b/a The Hubbard Association, was licensed to practice professional engineering in the State of Florida, having been issued license number PE 006634 on August 17, 1962. Certificate of authorization number EB0003297 was issued to the firm, The Hubbard Association, Inc., on September 25, 1981. In March 1986, Respondent prepared a set of plans for the proposed City of Macclenny Wastewater Treatment Works Improvement Program, Sewage Treatment Facility ("Macclenny project"), and one volume of "Contract Documents and Specifications" ("specifications"), which were submitted to the State of Florida Department of Environmental Regulation, Bureau of Wastewater Management and Grants (Bureau) on or about April 24, 1986. All wastewater treatment plans designs must go to the DER for approval prior to construction, and if a public entity wants grant funding for its wastewater treatment facility, the project must be reviewed and approved by the Bureau (now called Bureau of Local Government and Waste Water Financial Assistance) which administers State grant programs for wastewater treatment facilities. The Bureau reviews grant project plans and specifications to ensure that they: (a) comply with administrative requirements of the grants programs; (b) comply with minimum Federal and/or State technical standards for wastewater facilities; (c) are suitable for bidding; and (d) present a constructible project. The plans for the Macclenny project depict an existing treatment facility, a new clarifier to improve the removal of solids (an expansion of about 130,000 gallons per day in treatment capacity), and a new effluent pumping station to pump to an overland flow field (field) through a force main pipeline to spray risers. The risers would spray the water laterally across the field. Water would collect in a central collection ditch, and run through a final chlorine contact chamber prior to discharge in Turkey Creek. A new agricultural building for equipment storage, and a new holding pond, which is an off-line pond for storage of inadequately treated water, are also depicted. The field in the Macclenny project is roughly 24 acres and is located in a large area between the chlorine contact chamber and the holding pond. The field in this system has 5 cells. A cell is an area of land that can be independently controlled to allow loading/resting cycles in the treatment process. Each cell in a given field should be as near equal in size as possible to provide for equal treatment of the wastewater during the loading/resting cycles. Loading/resting cycles allows a cell within the field to "rest" (no effluent being pumped on to that cell) so maintenance mowing or harvesting can be accomplished and to "load" the other cells to revitalize the bacteria that renews the treatment process. "Load" means to apply the effluent or treated wastewater from the existing facility to the field. Generally, forty percent of the field would be loaded with wastewater at any one time. On December 9, 1985, the Bureau had a predesign conference with Respondent in Macclenny to discuss design items. No plans or specifications for the Macclenny project had been submitted at that time, nor were they submitted at this conference. On February 18, 1986, an in-progress design review was held at Macclenny, with the Bureau staff available to answer Respondent's questions. On March 5, 1986, another in-progress design review meeting was held in Macclenny, with the Bureau staff present, at which time the plans were "fifty percent" (50%) complete. The unsigned and unsealed plans were given to the Bureau for a preliminary review. On March 25, 1986, the Bureau issued a few preliminary comments on the 50% completed plans and specifications. The purpose of the 50% complete review is to help the design engineer complete his plans and specifications. On March 31, 1986, Respondent transmitted to the Bureau a set of plans for the proposed Macclenny project. Respondent's transmittal letter, which the Bureau received with the plans on April 11, 1986, stated that "completed plans" were being transmitted. On April 21, 1986, Respondent transmitted to the bureau an additional set of the same plans for the Macclenny project, which Respondent again referred to as "completed plans" on his transmittal letter form which were received by Bureau on April 24, 1986. This transmittal also included specifications, a design data check list, design calculations, cost estimate, and plan of operation. The plans in this submittal are referred to as "the plans." It was Respondent's understanding that signing and sealing a set of engineering drawings signified a legal obligation that if someone takes the plans and builds a project it will work. Respondent's signature and seal are on the first sheet of the set of plans which was in the April 1986 submittal but not on the specifications. The plans were prepared, signed, sealed and submitted to the Bureau for review by Respondent. Respondent did not place any conditional language or qualification on the plans or write a letter advising the Bureau that the plans were not complete. It was Respondent's understanding that the Bureau would not review a set of plans unless they were signed and sealed, notwithstanding the completeness of the plans. Respondent did not consider the plans as completed, notwithstanding that he had signed, sealed and submitted them to Petitioner as "completed". It was Respondent's understanding that the plans were being submitted for review only, not complete for construction. An engineer may get answers from the Bureau without submitting plans that are signed and sealed as completed, such as the predesign conference or 50% review that occurred in this case. The Bureau considers plans that are signed, sealed and submitted as "completed" for review to be 100% complete and ready to bid. The Bureau considered the plans and specifications which Respondent submitted on April 24, 1986 as being final, complete plans and specifications for final review by the Bureau. The Bureau reviewed the plans assuming them to be complete and followed normal procedures for reviewing a complete set of plans and specifications. On June 19, 1989, the Bureau issued 52 written comments based on its review of the plans and specifications it had received in the April 24, 1986 submittal from Respondent. The plans and specifications were submitted to the Department of General Services (DGS) by the Bureau for a review and opinion because the Bureau was concerned about the structural design. DGS responded to this request through Jim Berkstresser, P.E. on June 25, 1986. By cover letter dated July 18, 1989, Respondent filed written responses to the Bureau's 52 comments. The Bureau did not approve Respondent's plans and specifications for the Macclenny project submitted on April 24, 1986. On September 5, 1986, Respondent resubmitted plans in response to the Bureau's 52 comments. These plans had the same configuration as the April submittal regarding the overland flow treatment. On September 29, 1986, Respondent met with David Wolfe to discuss the field configuration for the proposed overland flow system and other outstanding issues related to the revised contract documents. The principal concerns were non- uniform flow and significant erosion potential. Respondent's plans did not follow accepted design criteria. At this meeting field configurations were discussed, as well as guidelines to be followed in design of the overland flow field, and a general field layout were developed. Respondent submitted another set of plans which the Bureau received on October 30, 1986, and that set was approved and stamped accepted by DER-BWMG on December 22, 1986. All sheets in the approved set are dated August 20, 1986, with the exception of the cover sheet on which Respondent failed to date his seal and signature, and sheets G-6 and G-7 which are dated October 24, 1986. Respondent signed and sealed the cover sheet and sheet G-7 of the approved set of plans, but did not seal any other sheets in the approved set of plans. A signature and seal on a set of plans indicates that the plans were prepared by, or under the direct supervision of the person signing and sealing them, and that the plans are complete and depict a project that will perform its intended function. A signature and seal on a set of plans means the engineer assures that the design is his design and that the plans and specifications are ready to be bid for construction. The design should contain criteria and information significant to ensure the project will work. Sheet flow is the primary treatment mode in an overland flow system. Sheet flow is where a thin layer of water is induced to flow in a very controlled atmosphere across a length of land that is functioning very similarly to a trickling filter. The acceptable range of slope of an overland flow system is 2% to 8% with the best results obtained in the lower range because of a longer "residence time". "Residence time" is the amount time the wastewater is on the field for treatment. The slopes must be even and uniform to maintain a constant velocity so as to minimize the potential for erosion and to maintain a constant depth of water throughout the filed so as to maximize the treatment. Cross slopes should be minimized and topographic lines should be as close to parallel as possible on the field. The plans for the Macclenny project shows: (a) slopes ranging from less than 2% up to 6%; (b) multiple compound slopes across the field and; (c) topographic lines that are not parallel. The specifications for the field do not set out the acceptable tolerances on the slopes or the acceptable level of compaction of the field for the contractor who is to construct the field and; therefore, lacks control over the final product. Contours in an overland flow field are important, and while it is desirable for them to be on 1-foot intervals, contours at intervals of 2 feet are acceptable provided the plans and specifications address what happens between the contours. Respondent's plans and specifications show contours at intervals of 2 feet but do not address what happens between the contours. The plans of the facilities that were approved prior to the submittal of any plans by Respondent called for a 2- 3 week loading/resting cycle. The standard practice is to have all cells within an overland flow field to be of equal size so that the area to be loaded at any given period of time is the same size. The cells in the overland flow field in the Macclenny project as depicted by the plans are not of equal size, and if operated on a 2-3 week loading/resting cycle would not provide a consistent amount of treatment and thereby result in varying levels of treatment of the effluent. It is standard practice to provide performance specifications for seeding the field with the primary grass cover and for overseeding when necessary to prevent wind and water erosion. There were no performance specifications in the plans and specifications on the Macclenny project submitted by the Respondent. Agricultural equipment is an integral part of the overland flow field system and has a direct bearing on whether the system will function over the long run. Specifications for agricultural equipment are necessary to determine if the system will work properly. There were no specifications for agricultural equipment submitted by the Respondent in the plans. It is standard practice to furnish spray nozzle specifications, such as nozzle size, degree of fanning, characteristics under varying pressures and how much water will be discharged by the nozzle, in a set of plans and specifications for an overland flow field. Respondent's specifications for the Macclenny project did not contain the necessary specifications for the spray nozzles. Compacting is a standard practice, and it is standard practice to show compaction requirements on plans or specifications. The usual practice is to investigate the soil and specify compaction, usually based on a foundation report by a geo-technical engineer, showing the safe beading capacity of the soil in what condition, with recommendations for compaction. The Respondent's specifications do not call for compaction of the soil under the clarifier slab. However, the Respondent's specifications do call for compaction in the holding pond and situations where an area is over-excavated and backfilled. Should the area under the clarifier slab be over- excavated and backfilled, then compaction is covered in the specifications but compaction would not be covered unless this occurs. Therefore, since the weight of the slab is carried by the soil beneath it, specifications for compaction should have been included in Respondent's specifications for any situation. Changes in temperature causes concrete to expand or contract which may result in cracking. Placement of a concrete slab may result in the slab bending which may result in cracking. Therefore, reinforcing a concrete slab is required to maintain the slab's integrity. The thickness of a concrete slab will determine the distribution of the reinforcing so that cracking is minimized. The clarifier slab in the Macclenny project is depicted as being 12 inches thick and shows number 6 bar reinforcing on 6 inch centers in the top of the slab but no reinforcing in the bottom of the slab. Failure to require reinforcing in the bottom of the slab could result in the slab cracking due to significant changes in temperature and soft spots in the soil beneath the slab. Failure to place reinforcing in the bottom as well as in the top of the slab is not in accordance with standards of the code of the American Concrete Institute (ACI), revised in 1983, and is a structural weakness. The chlorine contact chamber as detailed on sheets 5-6 and 5-7 is like a rectangular concrete box beneath the earth where the earth is within a few inches of the top of the walls. The walls are vertically reinforced with number 4 bars on 12 inch centers placed in the center of the 8 inch thick wall. When the tank is empty the reinforcing bars will be approximately 160 per cent overstressed from the active pressure of the earth. Additional reinforcing is needed in the walls to meet ACI standards. There are deficiencies in the vertical wall reinforcing of the chlorine contact chamber as detailed on sheets 5-6 and 5-7 of the Plans. On sheets 5-3, 5-4 and 5-7 of the plans, reinforcement through the construction joints is incorrectly detailed to assure that cracking of the concrete will not occur. Construction joints occur between different pours of concrete, such as where the walls meet the top of the bottom slab. The concrete bottom of the holding pond as detailed in sheet 5-8 of the Plans is large enough to require expansion joints to prevent cracking as the slab expands and contracts due to changes in the weather, yet no expansion joints are shown for the slab as detailed on sheet 5-8 of the plans. Neither the collection ditches nor the spray riser bases as detailed on the plans show any reinforcing to maintain the integrity of the concrete. While this is not a major structural weakness, it indicates a failure to comply with standard structural engineering practices. Although the plans call for relocation of an existing drainage ditch, the Respondent failed to consult DER regarding the permitting of such drainage ditch. A detention time of 30 minutes is required to properly disinfect wastewater and is-basic knowledge for all civil engineers, yet the plans called for only a fifteen minute detention time. It is standard engineering practice to provide flood level elevations on the site plans. Respondent failed to provide flood level elevations for the Macclenny facility site plans. The plans failed to: (a) provide elevations for high water alarm and pump off settings; (b) provide specifications for flume liner on sheet M-4; (c) show how to close an existing outlet on the chlorine contact chamber; (d) show where an effluent pump station was to be located; (e) show pressure relief valve locations and; (f) indicate quantities for purpose of contract bidding. The specifications list equipment and work items, such as pumping equipment, grit storage tank, case-out assembly, telescoping valve, air diffusers, portable pump, hose and couplings, that are inapplicable to the Macclenny project. There are inconsistencies in the plans and specifications, such as: (a) the plans showing one clarifier while the specifications call for two clarifiers, (b) the plans showing a 150 pound chlorine cylinder as opposed to a 1-ton chlorine cylinder in the specifications and; (c) the plans showing the clarifier with a 38-foot diameter while the specifications calls for a clarifier with a 40-foot diameter. Respondent was negligent in submitting incomplete plans to the Bureau as "completed plans" and in failing to utilize due care and failing to have due regard for acceptable standards of engineering principles, with regard to the content of those plans which he submitted as "completed plans".
Recommendation Having considered the foregoing Findings of Fact and Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the circumstances surrounding this case, it is, therefore, RECOMMENDED that the Board enter a Final Order finding Respondent, L. Thomas Hubbard guilty of violating Section 471.033(1)(g), Florida Statutes, and for such violation impose an administrative fine of $1,000.00 and suspend from the practice of engineering for a period of thirty (30) days, stay the suspension and place the Respondent on probation for a period of one year under terms and conditions the Board deems appropriate.

Findings Of Fact Respondent owns and operates a waste water treatment facility at Polynesian Village Mobile Home Park, owns the land at this village, leases these lots to mobile home owners, and provides them with waste water treatment. He was last issued an operating permit on January 18, 1983, by Petitioner. Respondent posted an Operational Bond (Exhibit 2) in the amount of $7,500 with Northwestern National Insurance Company as surety to faithfully operate the treatment facility and comply with all Rules and Regulations of the Petitioner. Englewood Water District, petitioner, was established by special act of the Florida Legislature in Chapter 59-931, Florida Statutes, and is given authority in Section 4 thereof to regulate use of sewers, fix rates, enjoin or otherwise prevent violations of the act or any regulation adopted by Petitioner pursuant to the act, and to promulgate regulations to carry out the provisions of the act. Pursuant to this authority, Petitioner promulgated Waste Water Treatment Facilities Design, Construction and Operation Regulations dated June 19, 1980, and revised April 28, 1983. During an inspection of Respondent's waste water treatment facility on October 17, 1983, leaching was observed at both the north and south drain fields with effluent from the system rising to the surface. Samples of this effluent when tested showed a fecal coliform count of 2800/100 ml. The basic level of disinfectant shall result in not more than 200 fecal coliform values per 100 ml of effluent sample (Rule 17-6.060(1)(b)3a, F.A.C.). Following this test, Notice of Violation (Exhibit 4) was served on Respondent. No action was taken by Respondent to correct this condition and on January 6, 1984, a Citation (Exhibit 5) was issued to Respondent scheduling a hearing for January 26, 1984. Following the issuance of that Citation frequent inspections of the facility were conducted by employees of Respondent to ascertain if steps were being taken by Respondent to correct the deficiencies. Additionally, inspections were made by inspectors from Sarasota County Pollution Control. Inspections were conducted January 9, 16, 17, 18, 20, 23, and 31; February 1, 8, 13, 14, 16, 21, 24, 25, 26, 27, 28, and 29; and March 2, 5, 8, and 9, 1984. These inspections revealed what appears to be a "blow-out" in the south drain field where effluent bubbles to the surface and flows onto the adjacent streets and propert (Exhibits 9 and 11). Effluent tested from this source had fecal coliform counts as high as 9440/100 ml. During one of these inspections effluent from the treatment plant was being discharged directly onto the road to a drainage ditch adjacent to the plant (Exhibit 8). The coliform count of a sample taken from this ditch was 13500/100 ml. Respondent was issued a second Citation on March 2, 1984, and this hearing was held on the violations alleged in that Citation, to wit: creating a public nuisance and leaching from drain field. Respondent contends that he is dealing with the Sarasota County Engineer to correct the problems and, after failing in his attempt to get the county to provide drainage from his property, he is now in the process of installing drain pipes. Respondent contends that the natural drainage of surface waters from his land to adjacent land was stopped by development on the adjacent land and the heavy rains this winter has saturated his land and inhibited percolation in the drain fields. Accordingly, the effluent from his plant could not be absorbed by the drain field. Respondent also contends that the drain field worked fine for several years before the drainage problem arose and believes it will again work well when the drainage situation is corrected.
Findings Of Fact During 1990, Respondent/Applicant, City of Lynn Haven, filed several applications with the Respondent, Department of Environmental Regulation, seeking the issuance of several permits to build a wastewater collection system and a two million gallon per day advanced wastewater treatment (AWT) plant. The proposed facility is intended to replace the wastewater treatment facility currently being used by the City of Lynn Haven. After a review of the applications the Department proposed several Intents to Issue covering the different aspects of the proposed projects. The Intents to Issue included: A) a variance and dredge and fill permit, pursuant to Sections 403.201, 403.918, 403.919, Florida Statutes, and Rule 17-312, Florida Administrative Code, authorizing a subaqueous crossing of North Bay (Class II waters) and installation of a force main (permit #031716641), B) a collection system permit, pursuant to Chapter 403, Florida Statutes, and Rules 17-4, 17-600 and 17-604, Florida Administrative Code, for the installation of approximately 11 miles of pipe from North Bay to the proposed treatment plant, C) a dredge and fill permit #031785181, pursuant to Sections 403.918, 403.919, Florida Statutes, and Rules 17-4, 17-312, Florida Administrative Code, authorizing 10 incidental wetland crossings associated with the collection system, and, D) a construction permit #DC03-178814, pursuant to Chapter 403, Florida Statutes, and Rules 17-4, 17-302, 17-600 and 17-611, Florida Administrative Code, authorizing the construction of a 2.0 mgd wastewater treatment plant. Sand Hill Community Improvement Association challenged the Department's Intents to Issue. The Sand Hill Community Improvement Association (Sand Hill) is an association composed of 74 formal members plus numerous supporters. Both members and supporters are residents who live near the site of the proposed Lynn Haven sewage treatment plant. They are sufficiently close to the plant site that construction of the proposed project could impact their property. The members are very concerned about any threat of pollution to the aquifer from the proposed plant since all of the members are dependent on private wells for their drinking water. Additionally, members of the association use the proposed site, as well as the associated wetlands, Burnt Mill Creek and the nearby lakes, for a variety of recreational purposes, including hunting, fishing, hiking, bird-watching, boating and swimming. Given these facts, the Association has standing to challenge the Department's Intents to Issue involved in this case. The City of Lynn Haven is located on a peninsular section of the south shore of North Bay and, except for its connection to the land, is surrounded by environmentally sensitive Class II or Class I waters. Lynn Haven's existing wastewater treatment plant was poorly designed, has not worked properly, and is old and outdated. The plant is permitted to treat up to 950,000 gallons per day. However, the existing plant is currently exceeding its originally permitted treatment limits and is treating in excess of 1,200,000 gallons per day. The sewage only receives secondary treatment, Secondary treatment is the minimum state standard for wastewater treatment. The secondarily treated wastewater is pumped several miles to a spray irrigation site located in the eastern portion of the City. The sprayfield site has never worked properly due to a high groundwater table and a confining layer of soil, both of which prevent the effluent from percolating into the ground. Because the sewage effluent cannot percolate into the ground, the existing operation frequently results in direct runoff into a ditch which empties into North Bay, a Class II waterbody. Such discharge of wastewater effluent into Class II waters is prohibited by Department regulations. 1/ At this time, the existing wastewater treatment facility is in violation of both DER and EPA standards and is under enforcement action by both agencies. The existing facility is currently operating without a permit and the Department has advised Lynn Haven that the existing facility as it now operates can not be permitted. In fact, all the parties agree that the City is in serious need of a wastewater treatment facility which works and does not pollute the environment. However, the parties disagree over the method by which proper wastewater treatment could be accomplished by Lynn Haven. Since 1972, the City, through various consultants and with the aid of DER, has reviewed approximately 40 alternatives for wastewater disposal. After this review, the City of Lynn Haven selected the alternative which is the subject of this administrative hearing. The alternative selected by the City of Lynn Haven consists of the construction of a proposed advanced wastewater treatment (AWT) plant and distribution system. The new plant will be on a 640 acre parcel of property located approximately 12 miles north of Lynn Haven. The location of the new plant will necessitate the rerouting of the wastewater from the old plant to the new plant by construction of a new transmission line approximately 12 miles north of the City across North Bay and parallel along State Road 77. 2/ The treatment process proposed for use in the new AWT plant is known as the AO2 process. The process is patented. The AO2 treatment process primarily consists of biological treatment with settling and filtration. The treatment process also includes a chemical backup treatment to further reduce phosphorus if necessary. The evidence demonstrated that this type of facility has been permitted by the Department in at least five other wastewater facilities throughout the state. The treatment facility will have a two million gallon per day, lined holding pond on site for the purposes of holding improperly treated wastewater for recirculation through the proposed facility. Any excess sludge generated by this treatment process would be routed to lined, vacuum-assisted, sludge drying beds. The sludge would then be transported offsite to a permitted landfill for disposal. The evidence demonstrated that this treatment process would not produce any objectionable odors. Once the wastewater is treated, it will be disinfected by chlorination to eliminate pathogens. The chlorination process is expected to meet state standards. After chlorination, a dechlorination process would occur to remove any chlorine residuals which would have a harmful affect on the environment. The treated wastewater would then be re-aerated and discharged through the distribution system indirectly into a wetland located on the 640 acre parcel of property. The quality of the treated wastewater is expected to meet the advanced wastewater treatment (AWT) standards. These standards are five milligrams per liter total suspended solids (T.S.S.), five milligrams per liter BOD, three milligrams per liter nitrogen (N), one milligram per liter phophorus (P). Ph will be in the range of six to eight units on an average annual basis and can be adjusted up or down if necessary to meet the ph levels of the ecology into which the wastewater ultimately flows. This effluent quality is approximately five times cleaner than secondarily treated effluent. Additionally, as a condition of the draft permit, the proposed facility would be operated by a state-licensed operator and would be routinely monitored to insure that the treated wastewater effluent meets advanced wastewater treatment standards. Given these facts, the evidence demonstrated that the applicant has supplied reasonable assurances that the plant will perform as represented and that the effluent will meet the state standards for advanced wastewater treatment. As indicated earlier, the site for the proposed AWT plant contains approximately 640 acres and is located approximately 12 miles north of Lynn Haven in an area known locally as the Sand Hills. The City specifically purchased this parcel of property for the construction of the proposed wastewater treatment plant. The plant itself would be located in the northeast corner of the property. The 640 acre site was previously used for silviculture. The entire area is currently planted in pines except for a low area that is dominated by a pristine, woody wetland system of titi. The titi wetland is approximately 212 acres in size and generally runs through the center of the property from the northeast to the southwest. The wetland is low in acidity, with an estimated ph between 4 and 5. The site consists of hilly, mineralized soils. The soils within the forested wetland are organic in nature. Based on the evidence at the hearing, there does not appear to be any significant confining layers of soil which would prevent the treated wastewater from percolating in the soils and draining towards the wetland and ultimately into Burnt Mill Creek, a Class III waterbody. Once the effluent leaves the plant, it would go through a distribution system. The proposed distribution system will consist of six, 500 foot long, 12 inch diameter perforated pipes. Each 500 foot section of pipe has 100 one and one-half inch orifices which will discharge the treated effluent onto an eight foot wide concrete pad. This concrete pad will dissipate the effluent's energy, prevent erosion at the orifice site and insure that the effluent sheetflows onto and eventually into the sandy soils of the plant site and ultimately into the receiving wetland. The distribution pipes are located around the east, north and western portions of the receiving wetland and are variously set back from the receiving wetland approximately 80 to 200 feet. The distribution system is designed with valves to allow for routing of flow to different branches of the system if it is determined through long term monitoring that there is a need to allow for any of the receiving wetland to dry out. None of the distribution branches are located in any jurisdictional wetlands of the State of Florida. The receiving wetland will receive a hydraulic loading rate of approximately 1.8 inches per week once the new advanced wastewater treatment plant is operating at capacity. Both the surface waters and groundwaters on the 640 acre parcel flow from northeast to southwest across the property. The evidence clearly demonstrated that any treated wastewater discharged on the site would move down hill by surface or groundwater flows towards the wetlands in the central portion of the property and eventually discharge into Burnt Mill Creek located at the southwest corner of the parcel. The evidence demonstrated that it would be highly unlikely for the surface or groundwater to move in any other direction and would be unlikely for the surface or groundwater to move towards any residents located to the north or east of this parcel. Evidence of the topography and its relatively sharp gradient clearly demonstrated that the treated wastewater discharged in the northeast corner of this site would not result in any significant still water ponding and would exit the site at the southwest corner of the property in approximately 14 hours. The evidence did demonstrate that, depending on the wetness of the weather, there may likely be certain times of the year when a flowing type of ponding would occur. However, this wet weather ponding was not shown to be of a duration which would impact to a significant degree on the flora and fauna of the area or increase the number of disease bearing mosquitoes in the area. As indicated earlier the treated effluent from the proposed AWT plant will flow into Burnt Mill Creek. Burnt Mill Creek will ultimately carry the treated wastewater approximately 11 miles down stream to North Bay. The City can directly discharge up to two million gallons per day of AWT water into Burnt Mill Creek without violating state water quality standards. Therefore, the volume of wastewater discharged into Burnt Mill Creek should not have significant impacts on surface and ground water quality. Moreover, Chapter 17-611, Florida Administrative Code, authorizes the discharge of up to 2 inches per week to receiving wetlands provided wastewater is treated to AWT standards. The evidence demonstrated that this rule was developed as an experimental effort to determine if wetlands could be appropriate areas for wastewater effluent to be either discharged or treated. These state limits were intended to be very conservative limits and were designed to insure that the impacts to receiving wetlands would be minimal. The evidence and testimony demonstrated that the receiving wetland system involved in this case should not be adversely impacted beyond those limits set forth in Section 17-611.500, Florida Administrative Code, for flora, fauna, macroinvertebrates, fish or vegetation and will meet all standards set forth in Chapter 17-611, Florida Administrative Code. However, it should be noted that the wetland/wastewater program is highly experimental and very little is known about the actual impacts of wetland/wastewater systems since facilities similar to the one proposed by Lynn Haven have not yet been placed in service. The evidence did show that there would be some long term impacts to flora and fauna in the wetland area primarily due to ponding, changed ph and the introduction of nutrients and pollution in the form of the effluent. However, the regulation does allow for some change within a receiving wetland and the evidence did not demonstrate that these changes would be significant or detrimental. Petitioners' own witness concluded that other deep wetland treatment systems are doing a very good job in meeting state water quality standards. Although Petitioners' expert noted potentially adverse impacts to flora and fauna from other wastewater treatment systems, these other systems were slow moving, impoundment-type systems that are not similar to the wastewater/wetlands system proposed by the City of Lynn Haven. The Lynn Haven system is designed for percolation and sheetflow, not ponding. Though there should be some expected changes, no evidence was provided that the receiving wetlands for the Lynn Haven facility would be affected to the extent there would be violations of any standard as set forth in Chapter 17-611, Florida Administrative Code. In essence, the legislature has determined that such experimentation with wetland areas is appropriate, albeit, even with the conservative limits of DER's rule, may prove to be a mistake. This facility is designed to fit within that rule and in fact is probably the best technology available for use in a wetland/wastewater situation. Finally, in order to avoid any potential impacts on the area which may over time become significant an approved monitoring program for surface water quality and affects on flora and fauna, as well as a groundwater monitoring program are required as conditions of the permit. The groundwater monitoring program has been designed to monitor any potential long term impacts to groundwater. With these protections there should not be any significant adverse impacts to surface or groundwater quality and the applicant is entitled to a construction permit for the AWT plant and distribution system. Lynn Haven's sewage would reach the proposed AWT plant through a transmission line. The transmission line would run from Lynn Haven's existing wastewater treatment plant across North Bay and through the unincorporated area of South Port. The Southport area is not sewered and utilizes individual septic tanks for its sewage. The transmission line would be constructed entirely in state road right-of-way. The line would terminate at the 640 acre site described above. A new, variable speed pumping station would be constructed adjacent to the old wastewater treatment plant. From this pump station, a 24 inch line would be constructed on City right-of-way up to the south shore of North Bay. At this point, the transmission line would be reduced in size to 20 inches and would be embedded approximately three feet below the Bay bottom. An additional variable speed pumping station would be located approximately half way along the 12 mile route of the transmission line to insure adequate pressure to pump wastewater to the new wastewater treatment plant. The pumps are to be employed to insure that the wastewater is continuously pumped uphill to the new site so that waste does not set, become septic, and create odor problems. The pumps are equipped to provide for chemical control of odor if necessary. Also, as a condition of the permit, the pumping stations are required to have backup power supplies should power be lost to the stations. The pumping stations and backup power supplies are to be tested monthly and the pumps are required to be continuously monitored by radio telemetry to insure they are operating properly. Additionally, the City of Lynn Haven will be required, as a condition of the permit, to visually inspect the entire length of the wastewater transmission line three times per day. The portion of the transmission line which would cross North Bay is approximately 3000 feet in length and would be constructed of high density polyethylene pipe (HDPE) with a wall thickness of one and one-half inches. HDPE pipe is used to transport materials such as hazardous wastes where leakage is not permissible. This type of pipe is virtually inert in that it is highly resistant to corrosion and other chemical reactions. It is also impact resistant and has a very high tensile strength. The pipe comes in 40 foot segments and is heat welded (fused) together. This type of joint significantly reduces the chance of any leakage. In fact, leakage around pipe joints is more likely to occur with other types of pipe and pipe connections. HDPE pipe is currently carrying wastewater across Watson Bayou in Bay County, Florida. 3/ There have been no reported problems with leaks or breaks occurring in the pipe crossing Watson Bayou. Given these facts, the probability of the proposed HDPE pipe leaking or breaking is extremely low, albeit not impossible, and such pipe appears to be the best material available for constructing a wastewater treatment transmission line across protected waters of the State. As a condition of the construction permit, the portion of the transmission line crossing North Bay will be required to have isolation valves at each end so that the pipe may be completely isolated in the event that it needs repair. The underwater portion of the line would be visually inspected by a diver twice per year and the line would be pressure tested before being placed into service. Additionally, pressure tests would be performed once a year. The construction permit also requires Lynn Haven to periodically inject dye into the proposed transmission line to check for any small leaks that may not otherwise be detected. Finally, the HDPE pipe would also be equipped so that television cameras could be inserted into the pipe to routinely inspect the interior of the pipe. In the event the HDPE portion of the transmission line would need to be repaired, the line could be immediately, temporarily repaired by a dresser coupling. A permanent repair could then be made in less than 24 hours once the material and equipment were staged at the site. The City intends to locally stockpile all necessary parts and equipment to effect any required repair to prevent any delay beyond four days. Permanent repairs would be accomplished by floating the line to the surface. The area needing repair would be cut out and a new section would be put in place by heat fusion. The line would then be pressure tested to insure the absence of leaks and placed back into service. During this process, the line would be taken out of service by the isolation valves and flow would be diverted to the eight million gallon holding ponds at the City of Lynn Haven's existing facility. These holding ponds can hold four days worth of wastewater from the City of Lynn Haven. Lynn Haven is required, as a condition of the construction permit, to have this reserve capacity as well as have a contractor on standby to make any repairs in the event such repairs are necessary. All of the technical specifications for the transmission system and the operating conditions imposed on it are designed to insure that the system does not fail or develop any leaks which could impact receiving waters, including North Bay. Given the permit conditions, the required inspections for leaks, the sound engineering design and quick repair methods proposed, the evidence demonstrated that the probability of any leak occurring in the portion of the transmission line crossing North Bay is extremely low and that if such a leak does occur any potential harm to the environment will likely be limited and quickly eliminated. The evidence demonstrated that the design of the transmission line and permit conditions provide reasonable assurances that the transmission line will meet or exceed the Department standards set forth in Chapter 17-604, Florida Administrative Code. Therefore, the applicant has provided reasonable assurances that the transmission line/collection system will not violate Department standards or rules and the applicant is entitled to a permit (permit #CS03-178910) for the proposed collection system. In addition to requiring a construction permit/collection system permit for the wastewater transmission line, the line will also require dredge and fill permits and a variance for crossing waters of the state. There are ten incidental crossings of state waters and one major crossing o f North Bay. Of the ten incidental crossings, two are over small creeks (Scurlock and Little Burnt Mill) These two incidental creek crossings will be accomplished by placing the transmission line (ductile iron pipe) on top of pilings placed in the water. Best management practices such as turbidity curtains and other erosion control practices are proposed and required by the permit to minimize construction impacts on water quality. The only impacts to wetland resources would be from the placement of the pilings. The evidence demonstrated that any impact would be minimal and not significant. The evidence did not demonstrate that the aerial crossings would have any long term water quality or environmental impacts. The remaining eight incidental crossings of waters of the state consist of small, seasonally wet ditches which would be traversed by trenching and burying the transmission line. Again, turbidity controls such as curtains and hay bales would be employed to protect water quality. The evidence did not demonstrate that any significant long term or short term impacts to resources of the state would occur. The evidence did demonstrate that the applicant has provided reasonable assurances that water quality standards would not be violated in regards to these 10 incidental water crossings. Likewise, the evidence demonstrated that the construction of these 10 incidental water crossings would not be contrary to the public interest. Therefore, the applicant is entitled to issuance of a dredge and fill permit (permit #031785181) for these 10 water crossing. However, a much harder question arises in relation to the dredge and fill permit and the variance required for the 3,000 foot segment of the wastewater transmission line which crosses North Bay. Pursuant to Rule 17- 312.080(7), Florida Administrative Code, permits for dredging and filling activity directly in Class II waters which are approved for shellfish harvesting by the Department of Natural Resources (DNR) shall not be issued. The reason for the rule is that any pollution caused by dredging and filling and, as in this case, the permanent placement of a sewage pipe in food producing waters could potentially have catastrophic effects on more than just the environment but on local employment in the shellfish industry and the quality of food available to the State. Put simply, the Department has determined by enacting its Rule that the public interest in food producing waters far outweighs any other consideration or criteria under Sections 403.918 and 403.919, Florida Statutes, in determining whether dredging and filling should take place in Class II, shellfish waters. In other words, it is not in the best interest of the public to allow dredging and filling so that a pipe carrying raw sewage can be placed in shellfishing waters. However, irrespective of this determination, the Department believes that, pursuant to Section 403.201(1)(c), Florida Statutes, it may grant a variance from its rules to relieve a hardship. As indicated earlier, North Bay is a Class II waterbody, conditionally approved for shellfishing. North Bay, therefore, falls within the Rule's prohibition against dredging and filling in Class II waters and the City is required to demonstrate the presence of a hardship in order to vary the Rule prohibition and obtain a dredge and fill permit for the North Bay crossing. On issues involving variances, the Department employs a two step analysis. The first part of the analysis is whether a hardship is present and the second is whether, if the variance were granted, would it result in permanent closure of Class II shellfish waters. The Department correctly recognizes that the question of whether a hardship exists is a question of fact and is determined on a case-by-case basis. Surprisingly, in a kind of "what we don't know can't hurt" posture the Department reviews a request for a variance standing alone based on the application as it is presented and does not require analyses of other possible alternatives to the granting of a variance. However, the existence of any alternatives, costs of any alternatives, timeliness of any alternatives, problems with any alternatives, whether an alternative represents a short term or long term solution to a given problem and the implementability of any of the alternatives are all factors utilized by the Department in determining whether or not to grant a variance. The Department's policy of non- review makes no sense, either factually or statutorily, when the Department is faced with varying a prohibition it created in its own rules. Similarly, the Department's policy of not requiring other alternatives to be examined before granting a variance goes against the fact that an applicant has the burden to establish entitlement to a permit and, in the case of a hardship variance, that a hardship exists because reasonable alternatives to granting a variance are not available. 4/ Likewise, the second part of the Department's hardship analysis relating to the permanent closure of shellfishing waters makes no sense given the fact that a non-permanent closure of shellfishing waters may have the same or just as serious effect on employment in the shellfishing industry, the loss of income due to an inability to earn a living in that industry and health risks posed by contaminated seafood. Temporary loss of income or a livelihood can, for all practical purposes, have consequences to the persons directly affected by a temporary closure of shellfishing waters similar in nature those caused by the permanent closure of shellfishing waters. The same can be said for health risks posed by a contaminated food supply. Rule 17-312.080(7), Florida Administrative Code, does not contain any exceptions for the temporary closure of shellfish waters. Nor is the rule limited to instances of permanent closure. Permanent closure is simpy not required in order to support a hardship under Section 403.201, Florida Statutes. Moreover, neither step in the Department's two-step analysis is included in any Rule promulgated by the Department. 5/ Without such a Rule, it is incumbent upon the Department or the applicant to demonstrate the underpinnings for this non-rule policy. No such evidence was presented at the hearing. In fact, the evidence presented at the hearing affirmatively demonstrated that the Department's non-rule policy violated both its own rules and the statute under which it is trying to proceed. As indicated, the issue of hardship is a question of fact and involves a weighing of all the facts and cicumstances involved in this project. In this case, there are shellfishing areas located close to the proposed location of the transmission line. North Bay is sometimes closed to shellfish harvesting by the Department of Natural Resources. These closures generally occur during wet weather conditions and are due to stormwater runoff and the failure of septic tanks in Southport. 6/ Additionally the current Lynn Haven system also contributes to the closure of North Bay. No competent, substantial evidence was provided that issuance of the permit and variance would result in the permanent closure of shellfish waters. The location of the proposed transmission line would be several hundred feet west of the Bailey Bridge embedded in the Bay floor. 7/ The proposed alignment of the transmission line through North Bay is in an area which is relatively biologically unproductive. The proposed placement of the transmission line avoids the few grassbeds that exist in the nearshore shallow areas except for approximately 200 square feet of grass. During construction of the line, these grasses would be removed immediately before the line is placed in a trench and then would be promptly replanted in the same area. The evidence demonstrated that the affected areas of grass should be able to reestablish itself. The evidence further demonstrated that there would not be any long term adverse impacts to these aquatic resources and there should not be any significant long term impacts on the balance of any aquatic life which may exist on the bay bottom. Water quality during construction will be protected by use of turbidity controls to control sediments. Therefore, any short term impacts on aquatic resources are likely to be insignificant. Concerns about long term adverse impacts to Class II waters are greatly reduced by the type of pipe and conditions in the permit which require that the transmission line be routinely inspected and tested to insure that there is no leakage and that in the unlikely event the line should need to be repaired, the line could be easily isolated and quickly repaired. The evidence showed that, to completely avoid Class II waters, the line could be moved several miles to the west or east of the line's proposed location or be placed over or under the Bay. If the line was moved west to the extent that it was in Class III waters, it would be over 40 miles long and would more than double the cost of the project. If the line was moved several miles to the east, it would go through the Deer Point Lake Watershed. The watershed is a Class I water supply for Bay County. Clearly, moving the line either west or east is not practical nor realistically feasible. Tunneling under North Bay would be very risky and is not technically feasible. The length of the tunnel would require steel pipe to be used. If tunneling could be done at all steel pipe would not provide the level of protection afforded by the HDPE pipe proposed by Lynn Haven. Placing the transmission line on pilings for an aerial route over North Bay is uneconomical and would create a potential hazard to navigation. Moreover, an aerial crossing would not solve any pollution problems should the transmission line leak or break and would also still involve a variance request since it would be necessary to dredge and fill in Class II waters for the placement of pilings or supports. Put simply, the evidence, showed that there was no realistic way to avoid Class II waters in North Bay given the location of the proposed wastewater treatment facility. A location which the City knew would require a hardship variance from the rule prohibition of dredging and filling in Class II, shellfishing waters. A hardship which the City created by site selection and which it hoped to overcome by strenuous permit conditions and futuristic speculative benefits to unsewered areas of the County. The existing treatment facility is operating in violation of both EPA and DER requirements, has been issued a notice of violation, is nonpermitted and is destined to be operating under a consent order. The system is hydraulically overloaded, handling approximately 1.2 million gallons per day while its rated capacity is 950,000 gallons per day. Refurbishing Lynn Haven's existing wastewater treatment facility would not be viable since the plant has outlived its useful life, is of a very poor design and probably could not be made to function within Departmental standards and water quality standards. The existing sprayfield does not function and results in overland flow of effluent which discharges to Class II waters. The high water table and presence of a semiconfining layer on the Lynn Haven peninsula virtually guarantee such discharges. Further, the plant only provides secondary treatment. Put simply, Lynn Haven needs another method of handling its sewage. The only remaining alternative to a Bay crossing is to tie into the existing Bay County system and any AWT wastewater treatment plant Bay County may build in the future. 8/ The existing Bay County system provides at most only secondary treatment. The Cherry Street facility, which is part of that system, functions essentially as a lift station rather than a treatment facility. The Military Point Lagoon portion of the system is nonpermitted and is operating under a consent order and has been the subject of enforcement action. The Department has an extensive agreement with Bay County requiring a significant and long term series of actions to deal with their wastewater treatment system. The modifications or improvements to the Bay County system to provide advanced treatment are not imminent and the final system conditions cannot now be determined as they will depend in large measure upon data and analysis remaining to be collected. Currently, the existing Bay County system processes a significant amount of industrial discharge and has a problem with phenols most likely due to industrial waste from two discreet industrial facilities in the County. 9/ However, all of Bay County's wastewater system problems are reasonably solvable and will be corrected in the near future, if they have not already been corrected. Additionally, the amount of sewage Lynn Haven would be sending into the current Bay County system probably would not significantly impact that system and its problems or the County's ability to solve those problems. The County is willing to accept Lynn Haven's sewage into its system and future AWT system. The connection into Bay County's system is a viable alternative currently in existence. Moreover, as indicated, Bay County has a long range plan to build an advanced wastewater treatment plant. As yet the plan remains "just a twinkle in the County's eye" and has not progressed to the design stage. However, this plan, of necessity, will eventually become reality in the next 5 to 10 years. The estimated cost to a Lynn Haven user for the Bay County conceptual system will be $25.00 per month in lieu of $15.00 for the proposed Lynn Haven system. These estimates are at best speculative. However, this cost estimate is not excessive given the fact that a Lynn Haven user lives in an environmentally sensitive area and a Bay County hook-up would eliminate the need to run a sewer pipe through food producing, Class II waters. 10/ Based on these facts, the evidence demonstrated that it was feasible for Lynn Haven to hook into Bay County's wastewater system without creating any more environmental impacts than that system is already experiencing and must solve and which, to a significant degree, have already been solved by Bay County. Given the existence of this alternative to crossing food producing waters and the fact that any future benefits are just as likely to be provided just as quickly by the County through AWT facilities, the applicant has failed to demonstrate the necessity for crossing North Bay and failed to demonstrate entitlement to a hardship variance for that crossing. Therefore, the applicant is not entitled to either a dredge and fill permit or variance for the proposed North Bay crossing.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is, recommended that the Florida Department of Environmental Regulation enter a final order issuing permit applications CS03178910, DC03178814, and 031785181, and denying the variance and permit number 031716641.

DIANE CLEAVINGER Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 27th day of November, 1991.
Findings Of Fact B. D. Taylor, Respondent, is the owner of a wastewater treatment facility near Panama City, Florida, which serves a community of some 125-150 mobile homes at Lane Mobile Home Estates. The facility has a 24,000 gallons per day capacity to provide secondary treatment of wastewater with percolating ponds. It was first permitted in 1971 upon construction and has been in continuous operation since that time. In 1980 Respondent employed the services of a consultant to apply for a renewal of its temporary Permit to operate a wastewater treatment facility. This application stated the temporary operating permit (TOP) was needed to give Respondent time to connect to the regional wastewater treatment facility. The schedule contained in the following paragraph was submitted by Respondent at the time needed to accomplish this objective, Following inspection of the facility, a TOP was issued December 5, 1980 (Exhibit 1), and expired January 1, 1983. TOPs are issued to facilities which do not comply with the requirements for Wastewater treatment. Exhibit 1 contained a schedule of compliance to which Respondent was directed to strictly comply to stop the discharge of pollutants from the property on which the facility is located. These conditions are: Date when preliminary engineering to tie into regional will be complete and notification to DER. July 1, 1981; Date when engineering to tie into regional system will be complete and notification to DER - June 1, 1982; Date construction application will be submitted to phase out present facility - March 1, 1982; Date construction will commence - June 1, 1982; Date construction is to be complete and so certified - October 1, 1982; and Date that wastewater effluent disposal system will be certified "in compliance" to permit - January 1, 1903. None of these conditions or schedules has been met by Respondent. The regional wastewater treatment facility was completed in 1982 and Respondent could have connected to this system in the summer of 1982. This wastewater treatment facility is a potential source of pollution. The holding ponds are bordered by a ditch which is connected to Game Farm Greek, which is classified as Class III waters. The size of Game Farm Creek is such that any discharge of pollution to this body of water would reduce its classification below Class III. On several occasions in the past there have been breaks in the berm surrounding the holding ponds which allow the wastewater in the holding ponds to flow into the ditch and into Game Farm Creek. Even without a break in the berm, wastewater from these holding ponds will enter Game Farm Creek either by percolation or overflow of the holding ponds caused by the inability of the soil to absorb the effluent. On January 28, 1983, this facility was inspected and the results of the inspection were discussed with the operators of the facility. The plant was again inspected on February 8 and February 18, 1983. These inspections disclosed solids were not settling out of the wastewater in the settling tanks; inadequate chlorination of the wastewater was being obtained in the chlorination tanks; samples taken from various points in the system, the ditch along side the holding tanks and in Game Farm Creek, disclosed excess fecal coliform counts; and that very poor treatment was being afforded the wastewater received at the plant as evidence by high levels of total Kejhdal nitrogen and ammonia, high levels of phosphates, high biochemical oxygen demand, and low levels of nitrates and nitrites. In July, 1983, in response to a complaint about odors emanating from the plant, the facility was again inspected. This inspector found the aeration tanks anaerobic, effluent had a strong septic odor, the clarifier was cloudy, the chlorine feeder was empty, no chlorine residual in contact tank, final effluent was cloudy, both ponds were covered with duckweed and small pond was discharging in the roadside ditch (Exhibit 14) Expenses to Petitioner resulting from the inspections intended to bring Respondent in compliance with the requirements for wastewater treatment facilities are $280.32 (Exhibit 9)
