The Issue The issue for consideration in the proceeding concerns whether the Petitioner is entitled to an on-site sewage disposal system permit ("OSDS") authorizing installation of an on-site sewage disposal system for property the Petitioner owns near the Suwannee River in Gilchrist County, Florida, in consideration of the relevant provisions of Section 381.272, Florida Statutes, and Chapter 10D-6, Florida Administrative Code, and whether the Petitioner should be entitled to pursue a variance from the permitting statute and rules embodied in that chapter of the code.
Findings Of Fact The Petitioner owns certain real property located in Gilchrist County, Florida on the east bank of the Suwannee River, adjoining the river. The property is more particularly described as Lot 9, Block B, Two River Estates. The property was purchased on January 3, 1985 and was platted as a subdivision on January 5, 1959. The lot in question upon which the OSDS would be installed should a permit be granted, is approximately one acre in size. On April 30, 1990, the Petitioner made application for an OSDS seeking authorization to install such a conventional septic tank and drain-field system for disposing and treating household sewage effluent on the subject property. The system would be designed to serve a single-family residence, containing approximately two bedrooms, and approximately 1,200 heated and cooled square feet of living space. Upon making application, the Petitioner was informed that he would have to obtain a surveyed elevation of his property, as well as the ten-year flood elevation for his property for the river mile of the Suwannee River at which his property is located. The Petitioner consequently retained Herbert H. Raker, a registered land surveyor, who surveyed the elevation for his property. Mr. Raker established a bench mark elevation of 29.24 feet above mean sea level ("MSL"). The site of the proposed OSDS installation on that lot has an elevation at the surface grade of 28.5 feet. The subsurface of the lot at the installation site is characterized by appropriate, "slight-limited" soil extending 72 inches below the surface grade of the lot. The wet season water table is 68 inches below the surface grade of the lot. Consequently, there is more than adequate slight-limited soil to handle disposal and treatment of the sewage effluent from a single-family residence, such as is proposed, since the wet season water table is 68 inches below the surface of the property. Thus, a more than adequate treatment space and appropriate soil beneath the bottom surface of any proposed drain field to be installed at the site would exist so as to comply with the pertinent rules cited herein. The problem with a grant of the subject permit consists only of the fact that the property lies beneath the ten-year flood elevation, that is, it is approximately 1.5 feet beneath that elevation. The Suwannee River Water Management District report submitted to the Respondent agency by the Petitioner in the application process for the OSDS permit (in evidence) reveals that the ten-year flood elevation for the property in question is 30 feet above MSL. The soils prevailing at the proposed installation site, the great depth of the wet season water table, and the fact that the lot is approximately one acre in size and above the minimum size requirements for the installation of an OSDS, all militate in favor of a grant of the permit, except for the basis for its denial initially, that is, that it is simply beneath the ten-year flood elevation for purposes of the prohibition contained in Rule 10D-6.047, Florida Administrative Code. Although located within the ten-year flood elevation, the site is not located within the regulatory flood way so that if a mounded system or other raised OSDS alternative system were proposed and installed, an engineer's certification would not be required regarding the issue of raising the base flood level by the deposition of fill at the installation site for purposes of Rule 10D-6.047(6), Florida Administrative Code. There is no central water system available to the property; however, although there was conflicting testimony about the distance the proposed installation site would be from a neighbor's potable water well, the testimony of the Petitioner is accepted as being most certain in establishing that more than the required distance from that potable water well exists between it and the proposed septic tank and drain-field installation site, since the Petitioner established that approximately 110 feet is the actual separation distance. The Petitioner purchased the property to construct a single-family residence for himself and his family. He expended a substantial sum of money for the property and is unable to use it for its intended purpose without the subject permit or at least a variance so as to authorize him to install an OSDS. The Petitioner offered no concrete proposals or plans for an alternative system which might reasonably accomplish treatment and disposal of the sewage effluent in question without harm to ground or surface waters or the public health. No substantial proof was offered of a system which would either dispose of and treat the effluent at a location above the ten-year flood elevation or, if still below it, would adequately treat and dispose of the effluent sewage to safeguard the public health and the ground or surface waters involved, such that its existence slightly beneath the ten-year flood elevation would only be a "minor deviation" from that portion of the permitting rules. In point of fact, it would seem that a mounded system would be feasible on a lot this size, especially in view of the fact that the bottom surface of the proposed drain-field trenches or absorption beds would only have to be raised slightly over 1.5 feet from the surface grade of the subject lot and installation site in order to comply with the ten-year flood elevation parameter, which was the only basis for denial of this permit application. No proof was offered concerning how such a mounded system would be designed, installed and otherwise accomplished, however. Upon denying the initial application for the OSDS permit, the Respondent advised the Petitioner that he should pursue a formal administrative hearing process rather than make application for a variance and proceed through the internal variance board mechanism operated by the department in order to obtain a variance from the requirements of Rule 10D-06.47(6), Florida Administrative Code. The Respondent advised the Petitioner of this because the subject property was located within the ten-year flood elevation of the Suwannee River; and as the Respondent interpreted the Governor's Executive Order Number 90-14, which incorporated by reference the "Suwannee River Task Force Report" commissioned by the Governor, the Order absolutely prohibited the granting of any variances authorizing installation of OSDS's beneath the ten-year flood elevation of the Suwannee River or the granting of any OSDS permits themselves authorizing such installations.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that a Final Order be entered denying the Petitioner's application for an OSDS permit.

The Issue The issues set forth in DOAH Case No. 84-3810 concern the question of whether the State of Florida, Department of Environmental Regulation (DER) should issue a permit to Homer Smith d/b/a Homer Smith Seafood (Homer Smith) to construct a wastewater treatment facility which is constituted of a screening mechanism, dissolved air flotation treatment system, sludge drying bed, pumping station and subaqueous pipeline. In the related action, DOAH Case No. 84-3811, the question is raised whether DER should issue a dredge and fill permit to Homer Smith for the installation of the aforementioned pipeline along submerged lands in Trout Creek, Palmo Cove and the St. Johns River.
Findings Of Fact Introduction and Background In 1982, Homer Smith, under the name of Homer Smith Seafood, established a calico scallop processing facility in the vicinity of the intersection of State Road 13 and Trout Creek in St. Johns County, Florida. From that point forward, Smith has owned and operated the processing plant. His plant adjoins Trout Creek, which is a tributary to the St. Johns River. Both Trout Creek and the St. Johns River are tidally influenced waters that are classified as Class III surface waters under Rule 17-3.161, Florida Administrative Code. The processing undertaken by Smith's operation at Trout Creek contemplates the preparation of the scallops for human consumption. In particular, it involves the purchase of calico scallops from Port Canaveral, Florida, after which the scallops are transported by refrigerated trucks to the processing plant. They are then unloaded into metal hoppers and directed into rotating tumblers which separate out the scallops from sand, mud and other extraneous material. The scallops are placed in a steam tumbler that removes the shells and then passed through a flow tank that washes away sand, grit and shell particles. The scallops are next passed through eviscerators. These eviscerators are long tubes of aluminum with roughened surfaces that pull the viscera off of the scallops. The detached scallops are then sent along a conveyor belt, with scallops in need of further cleaning being picked out and sent to a second eviscerator. The eviscerated scallops are then chilled and packed for marketing. It is the viscera and wastewater associated with this material that is the subject of permitting. Homer Smith is one of about six automated scallop processing plants located in Florida. Two other plants are within St. Johns County, on the San Sebastian River in St. Augustine, Florida. Three other plants are located in Port Canaveral, Florida. When Smith commenced his operation of the scallop processing plant in the summer of 1982, he discharged the scallop processing wastewater into an area described as a swamp with an associated canal which connected to Trout Creek. By the fall of 1982, Smith had been told by representatives of the Department of Environmental Regulation that to operate his facility with the discharge would require a permit(s) from DER. At the time of this discussion, automatic scallop processing was an industry for which appropriate wastewater treatment alternatives had not been specifically identified by the Department of Environmental Regulation or the United States Environmental Protection Agency. This was and continues to be the case as it relates to the promulgation of technology-based effluent limitations designed for calico scallop processors. This circumstance is unlike the situation for most other industries for which DER has established technology-based effluent limitations. To rectify this situation, Florida Laws 85-231 at Section 403.0861, Florida Statutes, requires DER to promulgate technology-based effluent limitations for calico scallop processors by December 1986. In the interim, consideration of any permits that might be afforded the calico scallop processors by the exercise of DER's regulatory authority must be done on a case-by-case basis, when examining the question of technology-based effluent limitations. DER sent a warning letter to Smith on April 20, 1983, informing the processor that discarding its wastewater into Trout Creek without a DER permit constituted a violation of state law. After the warning letter, scallop harvesting declined to the point that by mid-June of 1983 the plant had closed down, and it did not reopen until the middle part of September 1983. Upon the recommencement of operations, DER issued a cease and desist notice and ordered Smith to quit the discharge of wastewater from the facility into Trout Creek. On the topic of the cease and desist, through litigation, Smith has been allowed the right to conduct interim operation of his business which involves direct discharge of wastewater into Trout Creek, pending assessment of wastewater treatment alternatives and pursuit of appropriate DER permits. 1/ When Smith filed for permits on April 10, 1984, he asked for permission to dredge and fill and for construction rights pertaining to industrial wastewater discharge into the St. Johns River. The application of April 10, 1984, involved the installation of a wastewater treatment system and an associated outfall pipeline to transport treated wastewater to the St. Johns River from the plant location. This system would utilize a series of settling tanks and a shell-filter lagoon as the principal wastewater treatment. DER, following evaluation, gave notice in October 1984 of its intent to issue permits related to dredge and fill and the construction of the wastewater treatment facility. In the face of that notification, the present Petitioners offered a timely challenge to the issuance of any DER permits. In considering treatment alternatives, Homer Smith had employed various consultants and discovered that treatment beyond coarse screening had not been attempted in processing calico scallop wastewater. Those consultants were of the opinion that conventional treatment methods such as clarification, sand filtration, vortex separation, breakpoint chlorination, polymers and spray irrigation were of limited viability due to the inability to remove key constituents within the waste stream or based upon certain operational difficulties that they thought would be experienced in attempting those methods of treatment. As envisioned by the April 10, 1984, application for permit, interim treatment of the wastewater was provided by the use of a series of settling tanks and a shell-filter lagoon, within which system adjustments were made to the delivery of wastewater treatment. The April 10, 1984, permit application by Smith did not envision any chemical treatment of the wastewater aside from that which might occur in association with the settling and filtration through the shell-filter lagoon. Following DER's statement of intent to issue a permit for construction of the wastewater treatment facility as described in the April 10, 1984, application by Smith, DER became concerned about the potential toxicity of calico scallop wastewater, based upon its own studies. As a consequence, Smith amended the application for wastewater treatment facility to include use of chemical coagulation and flotation. This amendment occurred in March 1985, and the wastewater treatment process in that application envisioned the use of an electroflotation wastewater system. In view of toxicity problems experienced with the testing related to the use of an electroflotation wastewater treatment system, this treatment alternative was discarded in favor of a dissolved air flotation (DAF) system. This system was pursuant to an amendment to the application effective May 31, 1985. This amendment of May 1985 was in furtherance of the order of the hearing officer setting a deadline for amendments to the application. DER issued an amended intent to grant permits for the DAF unit and the associated pipeline and that action dates from June 28, 1985. The Petitioners oppose the grant of these permits for the DAF unit and pipeline, and under the auspices of their initial petition have made a timely challenge to the grant of a permit for the installation of the DAF wastewater treatment unit and associated pipeline. It is the DAF unit and pipeline that will be considered in substance in the course of this recommended order. On July 6, 1984, Smith sought an easement from the State of Florida, Department of Natural Resources (DNR) for the installation of the pipeline. This was necessary in view of the fact that the pipeline would traverse sovereignty lands which were located beneath Trout Creek, Palmo Cove and the St. Johns River. On December 17, 1984, DNR issued a notice of intent to submit that application to the Board of Trustees of the Internal Improvement Trust Fund with a recommendation of approval. This action was challenged by the Petitioners on January 7, 1985, in a petition for formal hearing challenging the grant of the easement. DOAH Case No. 85-0277 concerns this challenge to grant of an easement. Originally, by action of January 28, 1985, the easement case was consolidated with the present DER permit actions. At the instigation of DNR, the easement case was severed from consideration with the present action. The order of severance was entered on July 31, 1985. The DNR case will be heard on a future date yet to be established. The DNR case was severed because that agency preferred to see test results of treatment efficiencies following the construction of the DAF unit. By contrast, the present DER cases contemplate a decision being reached on the acceptability of the construction of the DAF unit and attendant features, together with the pipeline on the basis of theoretical viability of this entire system. This arrangement would be in phases in which the construction of the upland treatment system would occur within 90 days of the receipt of any construction permit from DER, followed by a second phase within which Smith would construct the pipeline within 60 days of receipt of any other necessary governmental approval, such as the DNR easement approval. Furthermore, DER would wish to see the results of an integrated treatment system involving the upland treatment by the DAF unit and its attendant features and the use of the pipeline and the availability of a mixing zone, that is to say the end of pipe discharge, before deciding on the ultimate question of the grant of an operating permit for the wastewater treatment system. The quandary presented by these arrangements concerns the fact that discharge from the DAF treatment unit would be temporarily introduced into Trout Creek, pending the decision by DNR to grant an easement for the pipeline and the necessary time to install that pipeline. Given the difficult circumstances of these actions, there is raised the question of the propriety of discharging wastewater into Trout Creek pending resolution of the question of whether DNR wishes to grant an easement to place the pipeline over sovereignty submerged lands. This is a perplexing question in view of the fact that DNR requested severance from the present action, thereby promoting further delay in the time between any installation of the upland treatment system and the pipeline. Finally, Trout Creek is an ecosystem which has undergone considerable stress in the past, and it is more susceptible to the influences of pollution than the St. Johns River would be as a point of ultimate discharge from the pipeline. This dilemma is addressed in greater detail in subsequent sections within the recommended order. Petitioner River Systems Preservation, Inc., is a nonprofit organization comprised of approximately seven hundred persons. The focus of the organization is to protect and enhance the environment of northeast Florida. The individual Petitioners, Pinkham E. Pacetti, Robert D. Maley, Ruth M. Whitman and others, are members of the corporation who own property or live near the scallop processing plant of Respondent Smith. In addition, Pacetti owns a marina and recreational fishing camp that is located across Trout Creek from Smith's plant. Pacetti's fish camp dates from 1929. On the occasion of the opportunity for the public to offer their comments about this project, a significant number of persons made presentations at the public hearing on August 29, 1985. Some members of the public favored the project and others were opposed to the grant of any permits. St. Johns County Board of County Commissioners, in the person of Commissioner Sarah Bailey, indicated opposition to the project, together with Bill Basford, President of the Jacksonville City Council. Warren Moody, the vice-chairman of the Jacksonville Waterways Authority spoke in opposition to the project. The Florida Wildlife Federation and the Jacksonville Audubon Society expressed opposition to the project. The officials related the fact of the expenditure of considerable amounts of public tax dollars to improve water quality in the St. Johns River and their concern that those expenditures not be squandered with the advent of some damage to the St. Johns River by allowing the permits in question to be issued. These officials considered the St. Johns River to be a significant resource which they are committed to protecting. The City of Jacksonville, Clay County, Green Cove Springs, the Jacksonville Waterways Authority, the Northeast Florida Regional Planning Council and St. Johns County expressed opposition to the project contemplated by the present permit application, through the adoption of certain resolutions. These broad-based statements of opposition were not spoken to in the course of the hearing by members of any technical staffs to these governmental institutions. Private members of the public, some of whom are affiliated with River Systems Preservation, Inc., expressed concern about water quality violations, harm to fish and other environmental degradations that have been caused by the Homer Smith operation in the past and their belief that these problems will persist if the permits at issue are granted. Those persons who favored the project, in terms of public discussion, primarily centered on the idea that, in the estimation of those witnesses, fairness demanded that Smith be afforded an opportunity to demonstrate that this proposed system of treatment was sound and the quality of the water being discharged from the Homer Smith plant was not as bothersome as had been portrayed by the persons who opposed the grant of environmental permits. Industrial Wastewater Construction Permit Treatment System Description of Homer Smith's Plant and Its Operation. The source of water used for the processing of the scallops at the Homer Smith plant is a well which is located on that property. Homer Smith is allowed to withdraw 300,000 gallons of water per day in accordance with a consumptive use permit that has been issued by the St. Johns River Water Management District. To ensure Smith's compliance with this permit, a metering device is located on the well. Typically, the plant operates an eighteen-hour day, five days a week, using water at a rate of 200 gallons per minute. This would equate to 215,000 gallons per day over an eighteen-hour day. Prior to the imposition of restrictions by the Department of Environmental Regulation through the consent order, this facility had processed as much as 40,000 pounds of scallops each day, for a total of 36,000 gallons each week, at a gross revenue figure of $225,000 per week. Characteristics and Frequency of Effluent Discharge The wastewater generated by the scallop processing that is done at the Homer Smith plant is principally constituted of the well water used to clean the scallops, proteinaceous organic materials, and metals. The metals are introduced into the wastewater stream from the scallop tissue. The wastewater stream also has a certain amount of sand and grit, together with shell fragments. The concentrations of organic materials within the wastewater stream are at high levels. There is also an amount of fecal coliform bacteria and suspended solids. The pollution sources within the wastewater stream include total suspended solids (TSS), biochemical oxygen demand (BOD), nutrients (nitrogen and phosphorus) and the coliform bacteria. In the neighborhood of 30 percent of the BOD in the wastewater is soluble. The balance of the BOD is associated with the suspended solids. With time the organic materials in the wastewater stream will decompose and with the decomposition present certain organic decomposition products, which would include ammonia, amines and sulfides. Heavy metals in the wastewater have been in the scallop tissue and are released with the cleaning of the scallops. These metals include cadmium, copper, zinc, iron, manganese, silver and arsenic. The presence of these metals within the tissues of the scallops are there in view of the fact that the scallops are "filter-feeders" which have taken in these elements or metals that naturally occur in the ocean water. The permit application contemplates an average of five days a week of operation for eighteen hours a day. Notwithstanding the fact that in the past the Homer Smith Seafood operation had processed scallops seven day week, twenty- four hours per day, Smith does not desire to operate more than five and a half days a week in the future. That is perceived to mean five eighteen-hour days and a twelve-hour day on the sixth day. The treatment system contemplated here is for a flow volume of around 200 gallons per minute during normal operation. The system can operate as high as 300 gallons per minute. That latter figure approaches the design capabilities of the treatment system proposed. Wastewater is discharged only when scallops are being processed. There is basically 1:1 ratio between the volume of well water used to process the scallops and the amount of wastewater discharged. Proposed Treatment System and Alternatives As already stated, there is no specific industry standard set forth in the DER rules which would describe technology-based standards for the treatment of calico scallop wastewater. In those instances where the agency is confronted with an industry for which technology-based standards have not been established, DER examines the question of whether that effluent is amenable to biological treatment as contemplated in Rule 17-6.300(1)(n)1., Florida Administrative Code, as an alternative. Biological treatment is a treatment form normally associated with domestic waste and the imposition of this treatment technique is in furtherance of achieving a secondary treatment standard found in Chapter 17-6, Florida Administrative Code, which results in 20 mg/L of BOD and TSS, or 90 percent removal of those constituents, whichever is the greater performance in removal efficiency. In the absence of specific standards related to the calico scallop industry, and in the face of the interpretation of its rules in which DER calls for an examination of the possibility of biological treatment as an alternative to treatment specifically described for a given industry, it was incumbent upon this Applicant to examine the viability of biological treatment of the scallop wastewater product. The Applicant has considered biological treatment as an alternative and rejected that treatment form, in that Smith's consultants believe the wastewater is not amenable to biological treatment. By contrast, Petitioners' consultants believe that biological treatment should be the principal focus in treating the scallop wastewater and contend that biological treatment is a more viable choice when contrasted with the option chosen by the Applicant. If this waste is not amenable to biological treatment, Rule 17-6.300(1)(n)1., Florida Administrative Code, envisions an acceptable or minimum level of secondary treatment shall be determined on a case-by-case basis. In the instance where biological treatment is not a reasonable choice, the Applicant is expected to achieve treatment results which are comparable to those arrived at in treating domestic waste by the use of biological treatment techniques. On this occasion, DER had not established what they believe to be a comparable degree of treatment for calico scallop waste, assuming the unavailability of biological treatment. The present case is a matter of first impression. As a result, the idea of a comparable degree of treatment shall be defined in this hearing process, assuming the inefficacy of biological treatment. In that event, DER must be assured that the proposed treatment plan has an efficiency that rivals the success which biological treatment promotes with domestic waste, taking into account the quality of the effluent prior to treatment, available technology, other permitting criteria and the ambient conditions where the waste stream is being discharged. In arguing in favor of biological treatment, Petitioners pose the possibility of an integrated system in which primary settling tanks or clarifiers would be used together with a biological treatment step, which is referred to as a trickling filter, followed by final settling by the use of tanks or clarifiers in an effort to achieve BOD concentrations in the range of 200 mg/L to 400 mg/L. In this connection, the dissolved air flotation system is seen in the role of alternative to the initial stage of settling of the constituents within the wastewater stream. It is not regarded as the principal means of treatment of the waste. The trickling filter system as a biological treatment medium involves the use of a bacterial culture for the purpose of consuming the oxygen-demanding constituents, BOD. The trickling filter technique, if a viable choice, has the ability to remove 70 to 75 percent of BOD and TSS. Petitioners suggest further treatment of the waste beyond primary and final settling and trickling filter can be afforded by involving activated sludge, which according to their experts would end up with a biological oxygen demand in the 20 mg/L range. Although the constituents of the Smith plant's waste are of a highly organic nature, and, at first blush a candidate for biological treatment by use of the trickling filter, the problem with this form of treatment has to do with the intermittent flow in the Smith operation. This intermittent flow is caused by the fact that the plant does not operate throughout the year. The plant operations are seasonal, depending on calico scallop harvesting which does not occur on a routine basis. Therefore, the problem is presented of trying to keep the biological treatment system "alive" and operating at levels of efficiency which can be expected to maintain the percentage of removal of BOD and TSS that a healthy system can deliver. The bacteria colonies which are vital to the success of the biological treatment system must be fed on a continuous basis to maintain balance in the population of the colony. This would be a difficult undertaking with the Smith operation, given the interruptions in operations which could lead to the decline in the bacterial population and a poorer quality of treatment once the operations were resumed. This finding takes into account the fact that the colony can survive for a week or two by simply recirculating water over the filter. Obviously, in order to maintain necessary efficiencies within this biological treatment, the bacteria must do more than survive. The further suggestion that has been offered that the bacteria could be sustained for longer periods of time by feeding them seafood waste or dog food are not found to achieve the level of efficiency in the operation that would be necessary in posing biological treatment as an alternative. Again, it is more of an intervening measure designed to assure the survival of bacteria pending the continuation of the operations of the plant, as contrasted with a system which is continual and taking into account the uniformity of the waste product more efficient. Another problem with feeding the bacteria when the plant is not operating is that of disposing of the waste produced when this auxiliary feeding is occurring. Just as importantly, biological treatment is questionable given the long retention times necessary for that process and the build-up of toxic levels or concentrations of ammonia. The Applicant had employed an aerated lagoon in attempting to treat the waste and experienced problems with ammonia build up. Although this system did not call for the degree of treatment of the waste prior to the introduction into the lagoon that is contemplated by the present proposal of the Applicant, it does point to the fact of the problems with ammonia in the biological treatment system. Dr. Grantham, a witness whose testimony was presented by the Petitioner, conceded the difficulty of removing ammonia from the trickling filter. Moreover, the biological treatment system is not especially efficient in removing metals and phosphorus from the wastewater. Alternative treatment would be necessary to gain better efficiency in removals of those constituents. The trickling filter is expected to gain 50 percent metals removal, which is inadequate given the concentrations of heavy metals found in the scallop wastewater. Phosphorus could be removed after treatment by the trickling filter by the use of lime or alum. Assuming optimum conditions in the use of biological treatment after primary and final settling, thereby arriving at a BOD level of 200 mg/L, it would then be necessary to make further treatment by the use of activated sludge to see 20 mg/L BOD. The problem with activated sludge is related to the fact that this form of treatment is particularly sensitive to interruptions in flow, which are to be expected in this wastewater treatment setting. On balance, biological treatment does not present a viable choice in treating scallop waste. That leaves for consideration the question of whether the Applicant's proposal would afford a comparable degree of treatment to that expected in the use of biological treatment of domestic waste. The manufacturer of the dissolved air flotation unit or DAF system proposed, known as the Krofta "Supracell," offers another piece of equipment known as the "Sandcell" which in addition to the provision for dissolved air flotation provides sand filtration. The Sandcell might arrive at BOD levels of 400 mg/L. However, the testimony of the witness Lawrence K. Wang, who is intimately familiar with the Krofta products, in responding to questions about the use of the Sandcell system and suggestion that the system would arrive at 400 mg/L BOD responded "could be." This answer does not verify improvement through the contribution of sand filtration. For that reason inclusion of a Sandcell for filtration of BOD is not suggested in this fact finding and the system as proposed must be sufficient in its own right. Having realized the need to provide greater treatment than screening or filtering the waste stream, the Applicant attempted to design a treatment system using flotation technology together with chemical precipitation and coagulation. At first the Applicant examined the possibility of the use of electroflotation (EF). This involved the collection of wastewater in a retention tank and the generation of an electric current to create a series of bubbles to float insoluble flocs. Those flocs are caused by the use of ferric chloride, sodium hydroxide and various polymers which are added to the waste stream. The flocs are then pushed to the top of the chamber by the air bubbles, and this particulate matter is skimmed off by the use of a paddle. Pilot testing was done of the electroflotation technology and showed promising results, so promising that a full-scale electroflotation unit was installed and tested. The full-scale electroflotation showed reasonable removal of BOD, TSS, nutrients, coliform and trace metals. This technique was discarded, however, when bioassay testing of the treated effluent was not successful. In examining the explanation for the failure, the experts of the Applicant were of the opinion that certain chemical reactions were occurring as a result of the passage of the electrical current through the wastewater stream. When this problem with acute toxicity could not be overcome through a series of adjustments to the process, the Applicant decided to test another form of flotation, which is referred to as dissolved air flotation (DAF). This system employs the use of chemicals to create insoluble flocs. Unlike the electroflotation unit, though, it does not utilize electrical currents to create the air bubbles employed in the flotation. The dissolved air flotation thereby avoids problems of toxicity which might be attributed to the passage of electrical current through the water column. The present system as proposed by the Applicant has a number of components. The first component of treatment involves the passage of raw wastewater through a mechanical screening device, which is designed to remove a certain number of particulates by catching those materials on the screen. That material is then removed from the plant and disposed of off site. The balance of the wastewater after this first stage of treatment passes into a sump area and from there into a primary mix/ aeration tank. This water is then chemically treated to facilitate the formation of insoluble flocs. The chemically treated wastewater then enters a premanufactured Krofta Supracell 15 DAF unit which is designed to form bubbles by the use of pressurized air, with those bubbles floating the waste materials within the floc to the surface. Again, this method does not use electrolysis. The floated solid materials are then skimmed from the surface and directed to a holding tank and subsequently pumped to sludge drying beds. Some of the treated wastewater is recycled through the DAF unit after pressurization and in furtherance of forming the necessary bubbles for the DAF unit. The balance of the water is directed to a force main lift station. This water would then be transported through the eight-inch PVC pipe some 13,000 feet into the main channel of the St. Johns River where it is distributed through a five port diffuser. The screening mechanism spoken of had been installed in mid-December 1984 and has been used since that time to filter the wastewater. The screening mechanism is in substitution of settling tanks and shell pits. The shell pits which had been used before presented problems with odors as well as the ammonia build up which has been addressed in a prior paragraph. The removal efficiency of the screening mechanism is 30 percent of particulates associated with pollution parameters, as example BOD, total Kjeldahl nitrogen, total phosphorus and TSS. The frequency of the transport of these screened materials to the off site disposal is four to six times a day and the screen is decontaminated at the end of each day when the operations are closed. The application contemplates the same operating procedures of disposal and maintenance with the advent of any construction permit. The primary mix/aeration tank aerates the wastewater and through that process and the retention time contemplated, equalizes the flow regime and promotes a more balanced concentration of waste materials prior to the introduction of that wastewater for chemical coagulation and flotation. This step in the treatment process enhances the treatment efficiency. Some question was raised by the Petitioners on the size of the primary mix-aeration tank as to whether that tank was sufficient to equalize the flow, and conversely, the impacts of having too much retention time built into that tank, which would promote the build-up of toxic concentrations of ammonia in the wastewater. The retention time within the sump and the primary mix-aeration tank approximates one and one-half hours. The retention time and size of the primary mix-aeration tank are found to be acceptable. This design appropriately addresses concerns about the build-up of decomposition products and toxicity, to include ammonia. The sludge which collects in the primary mix-aeration tank will be pumped back to the sump pit by return flow. The sump pit itself will be pumped out in the fashion of cleaning a septic tank on the basis of once a week. The sump pit also receives the return flow of leachate from the sludge drying bed. Once equalization of flow is achieved in the primary mix-aeration tank, that wastewater is then treated by the use of alum, sodium aluminate and polymers. The purpose of this treatment is to convert soluble and insoluble organic matter such as TSS and BOD, trace elements and phosphorus into insoluble flocs that can be removed by flotation. These combinations of chemicals and dosage rates have been tested in electroflotation and dissolved air flotation bench and pilot scales for use associated with this project and a list of appropriate chemicals and ranges of dosage rates has been determined. It will be necessary for these chemicals and general dosages to be adjusted in the full- scale operation under terms of the construction permit. This facet of the treatment process must be closely monitored. Once the wastewater stream has received the chemical treatment, it is introduced into the Krofta Supracell 15 DAF unit. This unit is 15 feet in diameter, and within this cylinder bubbles are generated by pressurizing some of the chemically treated wastewater and potentially clean tap water. The use of clean tap water promotes dilution of the wastewater stream as well as greater efficiency in the production of the bubbles. Chemically treated wastewater is brought into the cylinder through the back of a revolving arm that moves around a center column of the DAF unit at the speed of the effluent flow. The purpose of this mechanical arrangement is to eliminate horizontal water velocity, to protect the integrity of the flocs that are being formed by the use of the chemicals. Those flocs float to the surface in a few minutes' time, given the normal turbulence and shallow depth of the DAF unit. This limited retention time also avoids ammonia build up. The floating material is then scooped and poured into a stationary center section and is discharged by gravity to the sludge holding tank. Wiper blades which are attached to the revolving arm scrape the bottom and sides of the tank and discharge any settled sludge to a built-in sump in the DAF unit. These materials which are settled in the bottom of the DAF cylinder are transported through the sludge holding tank and eventually placed in the sludge drying beds. The treated wastewater is removed by an extraction pipe associated with the center section of the DAF unit. It is then discharged. The use of clean tap water from the well and the ability to recycle the waste stream can promote greater treatment efficiency in terms of removal of undesirable constituents of the waste stream and the reduction of concentrations of those materials. As a measurement, approximately 8 percent of the wastewater flow will be removed as sludge. This sludge is sufficiently aerated to be reduced in volume by about one-half over a period of ten to thirty minutes in the sludge holding tank. It is then sent to the sludge drying beds. The sludge drying beds are designed to accommodate 30,000 gallons of sludge. They are 60 feet long, 25 feet wide and 4 feet deep. Those drying beds are of greater size than is necessary to accommodate the volume of sludge. The sludge drying beds have a sand and gravel bottom. The water drains from the sludge as leachate and returns to the sump pit in the treatment system at a rate of five to ten gallons a minute. Some concern has been expressed that the "gelatinous" nature of the sludge will make it very difficult to dewater or dry. This opinion is held by experts of the Petitioners, notwithstanding the fact that polymers are used in the treatment process. One expert in particular did not believe that the sludge would adequately dry. Having Considered the evidence, the opinion that the sludge will not dry sufficiently is rejected. Nonetheless, it is incumbent upon the Applicant to monitor drying conditions of the sludge very carefully and, if need be, to add some chemical such as calcium hydroxide to enhance the drying capacity of the sludge material. It is anticipated that the sludge will be removed once a day and this arrangement should be adhered to. With adequate drying, the sludge material can be removed with the use of shovels, rakes and a front-end loader as proposed by the Applicant. With frequent removal and adequate drying, problems with odors can be overcome, and problems with ammonia build up and the generation of unreasonable levels of bacteria can be avoided. Should problems with odors, ammonia and bacteria occur, it would be necessary for the Applicant to purge the drying beds, to include the sand and gravel which had been invested with the sludge materials that had caused the problems. Although Smith has not tested the drying bed leachate as to specific nature, the treatment process can be expected to deal with problems of any build-up of ammonia concentrations, fecal coliform bacteria and other organic decomposition products. This pertains to the ability to remove these offending substances from the site in terms of removal of the residual solids and the ability to treat those parameters within the leachate as the wastewater is cycled through the system. The treated wastewater will be transported to a pumping station by gravity flow and then pumped via the pipeline to the proposed point of discharge in the main channel of the St. Johns River. This pipeline is constituted of fabricated sections of pipe 20 feet in length, connected with bell and spigot joints, rubber gaskets and solvent welding. The treated wastewater is released into the river through a five point diffuser which has three-quarter inch openings angled at ten degrees from the horizontal bottom. The pipeline is anchored with prefilled 80-pound concrete bags attached with polypropelene straps which are placed at 8-foot intervals. These are placed to keep the pipe from floating. The diffuser is supported by four piles driven into the river bottom and surrounded by a series of concrete bags. The purpose of this arrangement is to hold the diffuser in place and to protect it against potential damage from anchors or other possible impact. The Applicant acquiesces in the choice to have the pipeline tested for leaks once a month in the period June through September and every other month during other parts of the year. If leaks are found, the Applicant would be responsible for repairing those leaks. As stated before, it is necessary for the Applicant to receive permission from the State of Florida to be granted an easement before the pipe can be installed. Prior to that permission being granted, the treated wastewater would be placed in Trout Creek, which is adjacent to the processing plant. Predicted End of Pipeline Quality of the Effluent In trying to predict the quality of effluent at the end of the pipeline, bench scale and pilot scale testing was done related to the DAF technology. This testing was done related to screened wastewater that was collected from the plant in April 1985. In this connection two series of DAF bench scale tests were performed. They related to samples collected on April 18 and 19, 1985, which were packed in ice and shipped directly to a research laboratory in Lenox, Massachusetts, where they were treated with chemicals and a laboratory size DAF unit. The concentration of the wastewater parameters were measured and recorded before and after treatment, and the results of those tests are set forth in the Applicant's Exhibit A-4(B)(3), at Table 2-1. The pilot scale testing that was done in this case related to a 4-foot diameter DAF unit which had been installed at the Homer Smith plant. This testing occurred in April 1985. The basis of the testing was samples taken on April 15 and 19, 1985. Again, wastewater parameters were measured before and after treatment and the results are set forth in Applicant's Exhibit A-4(B)(3), at Table 2-1. When the initial testing was done with the DAF, results for total coliform bacteria uniformly fell below a range of 35 organisms/100 ml. Subsequent pilot tests yielded higher bacterial counts which would indicate that there was a build-up of bacteria within the DAF unit. This verifies the need to require that the DAF unit contemplated by the application be routinely cleaned or sanitized to avoid the build-up problem. TSS in the pilot unit effluent was reduced to 40 mg/L and lower. The capacity for metals removal in the pilot scale testing was good pertaining to copper and zinc. The ability to remove cadmium showed a result of 0.013 and 0.015 mg/L. The best performance in the pilot scale testing related to BOD removal showed a value of 510 mg/L. It should be noted that the bench scale testing and pilot scale testing were in the face of significant variations in the amount of BOD presented by the screened wastewater. This identifies the need to pay close attention to the removal efficiency of the system related to the BOD parameter in order to achieve consistent levels of BOD following treatment. The system under review is referred to as full-scale treatment. This treatment can be expected to exceed the levels achieved in the DAF bench and pilot scale testing because: (a) As a general proposition, treatment efficiency improves as the scale of machinery increases from bench to pilot to full-scale; (b) The bench and pilot scale tests were run without the benefit of the primary mix-aeration tank and the benefits derived from that part of the treatment apparatus, that is to say, uniformity of the flow and better dispersion of the constituents of the wastewater stream, prior to chemical treatment; (c) The pilot DAF unit used exclusively recycled wastewater to undergo pressurization for the creation of the air bubbles. In the course of the hearing it was established that approximately 50 gallons per minute of clean tap water could be brought in to the treatment process resulting in the formation of more bubbles and the facilitation of up to 10 percent greater treatment efficiency based upon that change. The other contribution made by the use of clean tap water was the possibility of as much as a 20 percent dilution of the wastewater stream, in terms of concentration of constituents within the wastewater stream; (d) In a full-scale operation, the opportunity is presented to routinely adjust the chemical dosages as well as select among a range of chemicals in order to achieve the greatest treatment efficiency; (e) In employing routine sanitization of the DAF unit by use of a mild chlorine compound, the tendency to accumulate coliform bacteria can be overcome. Removal of this adverse influence improves the water quality. In traveling through the pipeline, the transit time is in the range of two to three hours. At a normal rate of 250 gallons per minute of discharge, the transit time in the pipeline is 2.25 hours. Given the constituents of the wastewater, bacterial populations can be expected and could conceivably consume sufficient amounts of oxygen to affect the dissolved oxygen levels within the wastewater as it exits the pipe at the diffuser ports. In addition, there is some possibility of ammonia build up within the pipeline. To avoid the build up of bacteria at harmful levels, sanitation of the DAF unit must be accomplished. In addition, the pipeline itself should be flushed with clean water at the close of operations each day and treated with small amounts of chlorine to address bacteria which may form within the pipeline. This avoids the increasing concentrations of ammonia and protects against lowered dissolved oxygen concentrations and the possibility of increased levels of toxic substances in the effluent which might be attributable to the proliferation of bacteria and the build-up of ammonia during the transport through the pipeline. Taking into the account the nature of this wastewater and the velocity associated with the transport and the sanitization of the pipeline, sedimentation associated with organic solids or other materials will not present a problem. The pollution parameters associated with the treated effluent at the point of discharge from the pipeline can be expected to meet Class III orders, excepting unionized ammonia, specific conductance, copper, cadmium, pH and zinc. In order to achieve satisfactory compliance with regulatory requirements related to those parameters, the Applicant has requested a two-meter mixing zone. The purpose of that mixing zone would be to afford an opportunity for dispersion and mixing in the ambient water before imposition of water quality standards. The implications of that mixing zone are discussed in a subsequent section to the fact finding within the Recommended Order. In effect use of the mixing zone will promote compliance with standards pertaining to the subject parameters. Petitioners point out the fact that the Applicant has based its assumptions on the results of treatment on the availability of four sets of data which were obtained from DAF effluent--two sets of data coming from the bench tests and two sets of data from the pilot plant. Further, there is an indication of the variation in quality of the effluent from one test to the next and the need to employ different dosage rates of chemicals in the face of those variations. The full-scale system utilizes a number of techniques to gain some uniformity in the quality of the effluent prior to chemical treatment and thereby some uniformity in the amount of chemicals necessary to treat the effluent. This overall system can then be expected to produce treated wastewater that is basically uniform in its constituents. Petitioners point out the limited amount of data in the testing related to BOD. There were, in fact, only two data points: one related to the bench system and one related to the pilot system pertaining to BOD, both of these the product of different chemical dosages for treatment. Again, the system that is at issue in this proceeding can be expected to arrive at a more consistent level of BOD than is depicted in the results pertaining to bench scale and pilot scale testing. In fact, those results were not remarkably disparate in that the bench sale test produced 560 mg/L and the pilot scale test produced 510 mg/L. While the data related to BOD is limited, it still gives sufficient insight as to the probability of successful full-scale treatment and the test data is found to be a reliable indication of success in achieving the goal of 510 mg/L BOD. Contrary to the Petitioners' perceptions, the treatment efficiency is improved with the system that is under review. Petitioners believe that the bench and pilot scale testing not only is unrepresentative of the full-size DAF system, they also believe that the full-size system represents a lesser quality of treatment. In this regard reference is made to features which would adversely affect the treatment efficiencies. The first of those pertains to leachate which drains from beneath the sludge drying beds and is recirculated to the existing sump pit and added to the waste stream. Sludge which sits in the drying bed does decompose and causes biochemical reactions to occur, as Petitioners suggest. Moreover, no specific testing has been done of the leachate to ascertain the ammonia concentrations, pH or other chemical characteristics. Nonetheless, given the intention to clean out the residual matter within the sump pit frequently, and the flexibility to make that cleanup more routinely, and the fact that this amount of leachate is comparatively small in its ratio to wastewater which is being sent through the system for treatment, the leachate is not found to be an unmanageable problem. Nor is the sludge a problem. Likewise, the amounts of heavy metals within the leachate can be accommodated. Concerns expressed by the Petitioners related to the organic materials in the primary mix-aeration tank that is being returned to the sump pit can also be dealt with by the evacuation of the materials in the bottom of the sump pit. This can be achieved more frequently than on a weekly basis if that becomes necessary, and in doing so avoid problems with concentrations of ammonia, bacteria, amines, sulfides and general organic decomposition products. These materials which are returned to the treatment process as wastewater reintroduced into the primary mix-aeration tank can be adequately addressed in the subsequent treatment that occurs by reaeration, the use of the chemicals and DAF flotation. The retention inherent in the sump pit, primary mix-aeration tank and sludge drying bed has a potential to cause problems with ammonia build-up; however, the problems can be satisfactorily addressed, as well as potential problems with other toxic substances in the effluent, by routinely taking the residual material in the sump pit and sludge drying bed out of the treatment system. While the specific chemicals and precise dosage rates to be used with a full-size DAF system remain open, the basic concept of chemical treatment has been identified sufficiently. The precaution that is necessary is to make certain that close monitoring is made of the results of changes in the chemicals and dosage rates. Likewise, special attention should be paid to the implications of adjustments in the pH of the effluent to make certain that compliance is achieved with the Class III water criterion related to changes in pH above background. Adjustments can be made without violating Class III water standards related to pH. In testing that was done pertaining to the electroflotation effluent, a number of other chemicals were observed, to include trimethylamine, dimethyl sulfide, chloroform and other hydrocarbons. There is some indication of the presence of dichleoroethane, ethylbenezene and other aromatics. The possibility exists that these substances may also be products within the DAF effluent. In that event, the critical question would be whether they have any adverse effect in the sense of influences on the ability of the effluent to pass bioassays and the ability of the effluent to comply with standards related to other parameters such as dissolved oxygen, BOD, and TSS. The routine testing which is called for by the draft permit, which is deemed to be appropriate, would create a satisfactory impression of the materials set forth in the paragraph in the sense of the implications of their presence and allow any necessary adjustments in treatment. While the effluent produced in the testing on the part of the Applicant is different, it is representative, and the treated effluent which will be produced in the full-scale system will be of a better quality and present less adverse impacts than shown in the past testing. Petitioners question whether the Applicant has given a conservative portrayal in analyzing the effluent. In particular, it is urged that the Applicant claimed to be vying for use of the bench scale testing as a conservative depiction of the results of treatment. In this connection, the impression given in the hearing was that of ascendancy in treatment efficiency beyond the use of bench scale, pilot scale and ending in full-scale treatment. As pointed out by Petitioners, in making his case the Applicant has used results of bench and pilot scale testing. As example, use was made of the results of testing in the pilot scale in describing the removal effioiencies related to cadmium, whereas in the measurements of nitrogen concentrations the bench scale result was better than that of the pilot testing and was utilized. The real question is whether the overall testing has given some reasonable indication of success in full-scale treatment. To that end, use of results from either the bench scale or pilot scale testing is appropriate, and those results point to success in the full-scale operation. The system that is proposed is designed to address fluctuations in flow and concentrations in the effluent, given the primary mix-aeration tank contribution and the ability to recycle flow within the DAF unit, with the use of clean tap water. This will allow the Applicant to deal with the remarkable differences in BOD that were seen in the test period, ranging from 900 to 3000 mg/L. COD data as well as BOD data is limited but is found to be an ample depiction of potential treatment efficiencies related to that former parameter. In addition to the aforementioned references to changes in chemicals in the treatment process, Petitioners characterize the use of clean tap water in the recycle flow as being "unsubstantiated speculation." While the use of tap water was discussed in a theoretical vein, that discussion is found to be an accurate assessment of the value of the contribution of clean tap water to the treatment system. Impacts on St. Johns River Ambient Water Quality and Conditions The St. Johns River and the area of the proposed discharge is a riverine estuary. It has a freshwater source flowing from the south and a tidal ocean boundary to the north. The confluence of freshwater flow and tidal influences causes the water movement within this area to be oscillatory. That is to say that at different times the water will flow downstream, to the north, and upstream, to the south. There are occasions in which the net flow over a given tidal cycle will be zero; however, the water is always moving. Conductivity and chloride data indicate that the freshwater flow is the dominant flow compared to tidal influences. The extrapolation of available flow data indicates that there is a net downstream flow of fresh water averaging approximately 6,000 CFS. The St. Johns River at the point of discharge is over one and a half miles wide and relatively shallow with maximum depth in the range of 3 to 3.5 meters. Given the fact of the width and depth in this segment of the river, and the imposition of wind conditions and tidal influence, the water is well mixed and flushed. There is no stratification in this portion of the river. The Applicant looked into the question of current bearing and velocity in depths between two to fourteen feet in the water column. Eleven sampling stations were utilized in arriving at information about current bearing. This observation was over an eleven-nautical-mile stretch of the main channel of the St. Johns River. These stations are depicted on Applicant's Exhibit 38. In this portion of the river the current at all measured depth was flowing up and down the main channel. Within these sections there is no indication of a pronounced subsurface water movement toward the east and west banks of the river. Current velocities within the three stations closest to the POD averaged in the range of 0.5 feet per second and velocities in the other stations found within the main channel were within that range of movement. By contrast current velocities within the embayment areas along the east bank of the river were substantially weaker. DER conducted two studies using tracing dyes poured into the St. Johns River at the approximate point of discharge and monitored the course of dispersement of that dye. During this observation the dye was constantly replenished while being carried on the currents. While the dye remained within the area of the main channel, it stayed on the east side of the river as it moved down river on the outgoing tide in the direction of Smith's Point and the Shands Bridge. As the tide was slowing before the change of tide, the dye drifted for approximately two hours in the immediate vicinity of the point of discharge. The DER dye study was a fairly gross measurement of the direction of water movement within the river beyond the point of discharge. It tended to confirm that the water flow was basically up and down river, depending on whether the tide is incoming or outgoing. The studies were not sufficiently refined to speak with any certainty on the possibility that some part of the flow regime would move toward the east or west bank of the river. Nonetheless, in examining the nature of the shallow embayment areas along the banks of the St. Johns River, they are not seen to be subject to the basic flow regime that is occurring in the main channel during tide events. The bathymetry in this area is such that if the main flow regime was having some influence on the embayment areas, the depths within those embayments would be more similar to the depths found in the main channel of the river. Petitioners have employed a number of dye and drogue measurements to try to give a more accurate depiction of the influence of flow within the main channel upon the dispersion of effluent upon discharge and the possibility of those pollutants reaching the embayment areas. While there is no dispute over the fact that Trout Creek is a tributary to the St. Johns River with some tidal influences being shown in that Creek and there is no dispute that water from the St. Johns River flows in and out of Palmo Cove and Trout Creek, there does not appear to be a significant flow of water from the St. John River into the cove and creek from the main channel, in particular from the area of the point of discharge. One of the witnesses of the Petitioners, Sandy Young, did a dye procedure in which a plume was allowed to develop over a distance of approximately 1,000 feet. Although some slight lateral variation was shown in the dye plume, it did not identify a basic flow pattern toward the embayment areas on the east side of the river. The DER dye study was over a distance of some eight thousand feet and also showed some minor lateral variation. Both of these dye studies tend to show a basic flow pattern within the main channel. The dye study run by the Petitioners' witness White gave the same basic depiction as seen in the studies by DER and Young and did not identify a flow pattern out of the main channel toward the embayment areas. In the drogue studies run by Young three Chlorox bottles were filled to 95 percent of volume with water and released at the point of discharge. They were followed for a period of five hours. They moved initially with the outgoing tide toward Jack Wright Island and then when the tide slowed, the drogues slowed. When the tide changed with the incoming tide, the drogues moved toward the center of Palmo Cove. The drogue studies by Young do tend to indicate that some water was exchanged from the main channel at the point of discharge and the embayment areas. It is not a very exact measurement as it only deals with the surface area of the water column, given the wind and wave conditions existing on that occasion. It is in no way representative of the flow direction of the rest of the water column. Therefore, although it may tend to identify that some of the pollutants leaving the point of discharge may find their way to Palmo Cove, it does not establish that quantity of that pollution dispersion and the significance of that dispersion. Based upon this evidence it cannot be seen to be so revealing that the assumptions made by the applicant in trying to identify the dispersion characteristics of the effluent at point of discharge are negated based upon the results of the drogue study. The drogue study which Young did and the observation of the movement from Smith's Point to Little Florence Cove are no more compelling than the dye studies done at the point of discharge. When the Petitioners suggest that there is some influence by centrifugal force pushing the water to the outside of the curve toward the eastern bank, they are correct. However, the contention by the Petitioners that the incoming and outgoing tides sweep to the eastern shoreline of the St. Johns River moving toward Pacetti Point, Palmo Cove, Florence Cove and Smith Point is not accepted. Again, the general flow regime is up and down the main channel of the river and not primarily to the eastern bank. Finally, the fact that the Tetratech data produced for the benefit of the Applicant showing the flow pattern within the overall water column, which indicated that the general direction is the same at the top or bottom of the water column, did not tend to identify the fact that pollutants throughout the water column will be dispersed into the embayment areas from the point of discharge. The data collected in the main channel seem to establish that the water was flowing up and down the channel at depths below the surface. The question becomes whether the amount of pollutants that are being brought into the embayment areas is in such concentrations that they tend to cause problems along the shoreline, especially as it pertains to dissolved oxygen levels. From the facts presented, this outcome is not expected. Levels of dissolved oxygen in the St. Johns River can vary in the natural condition as much as 2 to 3 mg daily. These variations are influenced by algal activity and are not uncommon in Florida waters. Dissolved oxygen is essential to aquatic life. Optimum levels of dissolved oxygen for the fish population of the river are in the neighborhood of 6 to 8 mg/L. DER has established a minimum DO standard of 5 mg/L for Class III waters such as Trout Creek, Palmo Cove and the St. Johns River. This standard is designed to achieve uniform compliance throughout water column at whatever time the measurement may be made. DER, by the employment of this rule, is attempting to deal with those instances in which, in view of the dissolved oxygen level, aquatic organisms are placed under greater stress. The lowest DO concentration expected is normally seen in the summer in July, August and September. DO concentrations in the water column are expected to be highest at the surface area and lowest near the bottom. Measurements near the bottom are significant in this instance because the discharge will occur approximately one foot off the bottom of the river. The Applicant took DO measurements of the area in question during the spring of 1984 over a period of three days. These measurements were taken at a time when a better quality of dissolved oxygen might be expected as contrasted with circumstances in the summer. With the amount of wind involved impressive levels of reaeration were also occurring. These measurements showed that in all stations DO levels were at least 5.0 mg/L at all depths. A study by Applicant's consultant Environmental Science Engineering related to a diurnal event for dissolved oxygen was taken approximately one kilometer downstream from the point of discharge in August 1985 and did not reveal any measurements below 5.0 mg/L. The river was choppy on that day and this would improve the quality of dissolved oxygen. Historical data by DER related to water quality at Picolata, which is south of the POD in the St. Johns River, reveals average DO levels of approximately 6 mg/L. Historical water quality data collected by the Florida Game and Freshwater Fish Commission near Green Cove Springs, which is several kilometers north of the point of discharge, indicated average DO levels in compliance with water quality standards. Diurnal data from near Green Cove Springs did not show any history of DO values below the state standards. There is other historical data, however, which indicates that DO concentrations in the general vicinity of the point of discharge do go below 5.0 mg/L. Game and Freshwater Fish Commission data indicate that the readings below 5.0 mg/L could occur as much as 10 percent of the time. This relates to the study done at Green Cove Springs. There does not appear to be any particular pattern to these events of low DO violations other than the expectation of their occurring in the summer months, occurring more frequently in the lower depths of the water column and in areas which are shallow with limited flow. The summer circumstance is one in which there is a possibility of very heavy rainfall followed by hot weather with overcast skies and no wind, and the DO values go down in that set of conditions. The DO values are, in addition to being lower near the bottom of the water column, likely to be lowest in the evening or early morning hours and persist in length of time from eight to ten hours. Some of the Florida Game and Freshwater Fish Commission data from Green Cove Springs depicted some DO concentrations as low as 1.8 mg/L at the bottom and 2.1 mg/L at the surface. The low readings that were taken at Green Cove Springs occurred in September 1979 after Hurricane David had created unusual conditions in the upper St. Johns River as to effects on DO. The same report indicated DO concentrations at eleven stations in the lower St. Johns River in July and September 1982 were in the range to 4.0 to 4.5 mg/L respectively. This particular data is not particularly valuable in view of the location of those stations. There are occasions when the DO concentration at the point of discharge could go below 5 mg/L and could be as low as 2 mg/L on the bottom, but this is not a routine occurrence and would not persist. The Petitioners' consultant Young had taken certain dissolved oxygen readings at the point of discharge in April 1985 and found compliance with the 5 mg/L standard. At other times he and the consultant white measured substandard dissolved oxygen concentrations at the point of discharge. On July 20, 1985, white collected water samples at the surface and at two feet above the bottom and determined that the readings were 4 mg at the surface and 3 mg near the bottom. On August 10, 1985, Young measured DO concentrations of 4 mg/L near the bottom. On August 30, 1985, Young measured DO values of 4 mg/L at the point of discharge. Young had also measured DO concentrations at Green Cove Springs on August 10, 1985, and discovered readings as low as .5 mg/L and ranging up to 3.8 mg/L. A downstream measurement away from the point of discharge in the main channel made on August 10, 1985, by Young showed a dissolved oxygen reading of 4 mg/L. In these August measurements Young had discovered a number of readings that were in compliance with the 5 mg/L requirement. Again on September 5, 1985, Young made a measurement of dissolved oxygen near the bottom of the water column at the point of discharge which was 5.3 mg/L. Young's measurements of dissolved oxygen at the surface and in the intermediate depth, typically were above 5 mg/L. Bottom readings taken by Young in the main channel of the river and to some extent in the embayment areas were extracted from the soft detrital materials, the place of intersection of the river bottom and the water column. DO levels in these anoxic materials would tend to give lower dissolved oxygen readings and, to the extent that this anoxic material remains in the test probe while taking measurements toward the surface, would have an influence on the readings, making them appear lower than would be the case if the anoxic sediments were not present in the test device. These effects were not so dramatic as to cause the rejection of the data collected by this witness. Some explanation for lower DO readings at the point of discharge can be attributable to the fact that the anoxic material associated with high benthic oxygen demand on the bottom reduces the dissolved oxygen in the water column. Although Rangia clams were present at the point of discharge and they are capable of living in an environment of low salinity and low DO, they are likewise able to live in higher ranges of DO and their presence cannot be regarded as meaning that the dissolved oxygen levels are consistently below 5 mg/L. Petitioners' consultant White opined that there would be a very frequent violation of DO standards at the point of discharge, approaching 25 percent of the time. Considering the facts on the subject of dissolved oxygen in that area, this opinion is rejected, as is the opinion that DO concentrations will go below DER standards most of the time in July, August, and September. Young believes that a more involved study of worst case conditions would reveal DO violations throughout the column in the center of the river. The data that was presented was ample to demonstrate that violations would not be that widespread. Nor is the opinion of the consultant Parks on the subject of DO violations, to the effect that they will occur on many occasions accepted. In the Palmo Cove area it is not unusual to see some DO readings below the 5 mg/L standards. The E.S.E. group found substandard DO conditions in Palmo Cove at sampling Station 1 in September and October 1984 and some instances in April and May 1985. DO concentrations were found in the range of .4 and .6 mg/L in August 15 and 30, 1984, respectively, with DO concentrations of 1.8 and 2.1 mg/L reported on October 4 and October 29, 1984, respectively. DO violations in four out of eight checking periods between April 25 and May 24, 1985, were shown in the Palmo Cove area. Measurements taken by the consultant white showed 3 mg/L at the surface and 2 mg/L at the bottom on July 28, 1985. The consultant Young also made a measurement of 3.2 mg/L of dissolved oxygen on August 10, 1985, in a mid-depth reading in the Palmo Cove area. On September 5, 1985, he found a DO reading of 4.0 mg/L. At those places along the eastern shoreline of the St. Johns River and the relative vicinity of Florence Cove, Jack Wright Island, Little Florence Cove and Colee Cove, low dissolved oxygen readings were found, that is below 5 mg/L. These coves can be expected to have substandard readings frequently during the summer period, based upon measurements taken by the consultant Young. In the conduct of the drogue study related to the Chlorox bottle, the consultant Young in tracking the path of those bottles, found a couple of locations in the path of the drogue which were in the range 2.8 to 4.2 mg/L and 2.0 to 4.6 mg/L. The influences of the discharge will not reduce DO in the embayments. The ambient conditions for BOD in the area where the discharge is contemplated is relatively low and there is no thermal or saline stratification even in the summer months. Nutrient concentrations in this part of the St. Johns River are as indicated within the Applicants Exhibit A-4(B)(3) and at present are at such levels as to promote a healthy fish community. There is algae production that can be sufficient in some areas within this section to cause algae blooms. Algae blooms are not found to be a routine occurrence. Algae blooms reflect higher levels of nitrogen and phosphorus. The consultants Young and White have seen algae blooms in the St. Johns River away from the general area of concern, both upstream and downstream. Should those algae blooms occur, they would promote significant rises and falls in DO concentrations. In Palmo Cove and the St. Johns River, supersaturated DO concentrations have been detected and they are indications of high rates of primary algal productivity. The circumstance of supersaturated conditions, related to dissolved oxygen, can be the by-product of an algal bloom. The concentrations of nitrogen range from an average of 1.42 to a maximum of 2.54 mg/L. Nitrogen concentrations of 1.4 mg to 1.5 mg/L are optimally advantageous for fish production. Significant increases above those levels would cause the decline of the fish population. Total phosphorus concentrations in the ambient waters are high. Concentrations in excess of 0.1 mg/L of total phosphorus are regarded as a indication of eutrophication and the average concentration here is measured as 0.3 mg/L with a maximum ambient concentration found at 0.52 milligrams per liter. There is significant algal growth in the inshore areas and an indication of some eutrophication in the grass beds. The dominant species of algae found in that vicinity are blue-green, which are seen as being nuisance species. The grass beds along the shoreline are basically healthy. On the other hand, some of the public witnesses identified the fact that grass beds and other vegetation have died with the advent of discharge from the Applicant's plant into Trout Creek. This was under a system in which little or no treatment was afforded the effluent. One other public witness indicated that his dock in the Florence Cove area had been covered with a slimy material and algae during the past two years. Significant grass beds are found along Jack Wright Island and in other areas along the eastern shoreline of the river. These grass beds are important as fish habitat to include nursery areas, areas for various juvenile species of fish and other organisms. Some of these grass beds are showing signs of environmental stress, and nutrient loading can contribute to that stress. Some of the grass beds are covered with higher amounts of algae, duckweed and periphyton than are desirable. The duckweed had floated into these areas from other locations and can be expected to move away. The presence of algae is an indication of nutrient loading. The presence of duckweed is not a product of nutrient loading in the sense of the production of the duckweed at the site where they were found along the shoreline. The area in question between Pacetti Point and Shands Bridge serves as a nursery in a sense of providing habitat for juvenile species of fish and other organisms. The grass beds along the shoreline provide habitat for feeding and breeding related to juvenile organisms, to include such species as bass and shrimp. Juvenile catfish are found within the deeper portions of the river as well as croaker and other marine species. There is a high number of juvenile blue crabs in this area of the river and this is a commercial resource. Shrimp are taken by recreational fisherman in the area of the North Shore Pacetti Point. Clam beds are also present near the point of discharge. Juvenile and adult manatee have been seen in the St. Johns River and in the area near Jack Wright Island. Manatee have also been observed in Trout Creek at a time before the operation of the Applicant's plant and at times following the cessation of operations in June 1985. During the course of the operation of the Applicant's plant, when raw effluent was discharged into Trout Creek, fish kills were observed. Those events had not been seen prior to the operation of the plant. Indications are that fish were killed in the creek due to the use by the Applicant of fly bait, which made its way into the water. Dispersion Modeling of Water Quality Impact In order to gain some impression of the influences caused by the dispersion of the pollutants within the effluent, the Applicant through its expert employed several modeling techniques. DER was made aware of this modeling as it developed. A far-field model was used to calculate what the long-term or steady state impacts of the treated effluent would be on the ambient water quality. In trying to identify the influence of the discharge, measurement of metals were taken based upon an assessment of long term increases. BOD, which breaks down and consumes oxygen over time, was examined in the sense of the long term effects as to DO deficits. In essence these projections were superimposed over the ambient condition to gain an impression of the adjusted ambient values, taking into account the influence of the discharge. The Applicant also ran a plume model which was designed to calculate spreading and dispersion of the treated effluent within the zone of initial dilution or mixing zone at the point of discharge. This model responds to the discharge configuration. Through the use of computer calculations, it was established that a five-point diffuser with port openings of 0.75 inches in diameter angled upward at ten degrees would result in an effluent dilution ratio of 28.5:1 within two meters of the point of discharge. The calculated impacts of the plume model were superimposed upon the adjusted ambient water quality conditions set forth in the far-field model in order to determine net impact upon the receiving waters within the mixing zone. A third model was used, referred to as the lateral diffusivity model. This model is designed to calculate the six-hour or short term water quality impacts of the treated effluent when it moves from the zone of initial dilution during flood and ebb tide conditions. By estimating dispersion rate, this model predicts what dilution would occur in the path of the effluent plume. These impacts were then superimposed upon the adjusted ambient water quality conditions to determine the total impact in the path of the plume. The modeling work by the Applicant's consultant is a reasonable depiction of the predicted impacts of the pollution on the ambient conditions. The calculations used in the far-field model assumed a freshwater flow of 2,000 CFS. This assumption in the far-field model satisfactorily addresses worst case flow conditions related to seven-day, 10-year low flow. The temperature utilized in depicting ambient water was 30 degrees centigrade when employed in the far-field and lateral diffusivity models. This corresponds to warm weather conditions, which are more profound in describing effects on water quality. The far-field and lateral diffusivity models assumed that the treated effluent discharged from the pipeline would have a BOD concentration of 665 mg/L. This is contrasted with the maximum concentration allowed by the draft permit, which is 510 mg/L, which is the expected amount of BOD. This tends to depict the impacts of the discharge more conservatively. The model assumes the BOD loading of 2,720 kg per week, equating to an average discharge concentration of 665 mg/L if the plant operates five days a week on an eighteen-hour day. The reaeration rate and NBOD and CBOD decay rates used in the far field and lateral diffusivity models are acceptable. Likewise, the longitudinal dispersion coefficient that was used in the far-field model is acceptable. The standard modeling methodology in this process calls for an assumption of a 1.33 growth rate of the plume in the lateral diffusivity model. The Applicant's consultant decided to use a lower constant diffusivity growth rate. As a consequence, less lateral spreading is depicted. With less lateral spreading, less dilution is shown, and the impacts predicted by the model are exaggerated. One of the parameters of the plume model has to do with river flow which causes some turbulence and also brings about dilution. In this instance the plume model calculations assume stagnant conditions which is a more conservative assessment. As the Petitioners have suggested, the modeling to explain the impacts of dispersion of the pollutants is not designed to give precise calculations of the DO deficit at each point in the river along the eastern shoreline. It is indeed an estimate. The estimate on this occasion is reasonable. Although DER performs mathematical analysis of dispersion of proposed discharge in some cases, it did not do so on this occasion. Nonetheless DER was satisfied with the present choice for modeling the dispersion characteristics of the discharge. Although the models utilized were not subject to exact calibration by measurement of the dispersion at the site, the information gained by the Applicant prior to the imposition of the modeling techniques was sufficient to develop the models and to give a theoretical verification of the expected impacts from the discharge. The Applicant's belief that the maximum DO deficit caused by the discharge will not exceed 0.1 mg/L is accepted. The dissolved oxygen level in the effluent at the point of discharge will be above 5 mg/L. The Applicant's choice of reaeration rates, CBOD decay rates, NBOD decay rates, discharge rate from the pipeline, hours of operation, average reversing current speed, net non- tidal flow, non-tidal velocity, time lag before NBOD decay, maximum tidal velocity, and other variables and assumptions within the models were acceptable choices. Although the possibility exists of an occasional 5 1/2 day operation in which 10 additional hours of operation are added, this would not be so significant as to set aside the predictions as to the pollutant dispersion. The Applicant's consultant who modeled the dispersion rates did not conduct dye studies to verify or calibrate the actual dispersion in the river. One of the dye studies indicated a lateral spreading rate which was less than that predicted by the model. Notwithstanding this revelation, the overall techniques used by the Applicant in predicting lateral spreading rate are sound and do not present a risk of a greater DO deficit than was predicted based upon incorrect assumptions as to lateral spreading rates. The Applicant's consultant's use of 2,000 CFS as the net non-tidal low flow was a more convincing estimate than the field data collected by the United States Geological Service, given the paucity of information about the flow conditions within the St. Johns River. The Applicant's choices in describing maximum tidal velocities and average velocity are accepted. The critique of the modeling efforts done by the Applicant that was made by Petitioners' consultant, Dr. Parks, in which he concludes that the DO deficit is considerably greater than 0.1 mg/L is not accepted. Comparison of Predicted Impacts of Discharge with Statutory and Regulatory Criteria Inside the Mixing Zone Applicant's assumptions about the increase in nutrient concentrations in the St. Johns caused by the discharge are accepted. This is based on the assumption of a nitrogen value of 52 mg/L which was achieved in bench scale testing of the effluent and which can be achieved in the full scale operation. As the effluent is discharged from the diffuser within the mixing zone, there will be some turbidity problems in that the bottom near the point of discharge. The soft silt there is easily resuspended. When the discharge is concluded, the material will settle back to the bottom. There will be further resuspension when the operation commences again and there is a discharge. The transport of these suspended materials is limited in that the water velocity associated with the discharge is quickly dissipated. This phenomenon will not cause adverse environmental impacts. The mixing zone does not include an area approved by the State of Florida, Department of Natural Resources for shellfish harvesting; it does not exceed the presumptive maximum size set forth in Rule 17-4.244, Florida Administrative Code. Nor does it include an existing drinking water supply intake or any other existing supply intake that would be significantly impaired by the proposed mixing zone. The water in this area is of sufficient depth that it will not support grass beds that are associated with a principal nursery area, such as pond weed, midgeon grass, manatee grass, turtle grass or eel grass which are used to support nursery activities. These grasses are normally found inshore. Although juvenile fish are found throughout this reach of the St. Johns River, and for that matter in the entire lower eighty miles of the St. Johns River, the mixing zone is not of such dimensions that it will preempt the health of juvenile fish. Most of the freshwater fish in this system use the littoral areas for reproduction. Marine and estuarine species do not reproduce in the St. Johns River. There is some reproduction that is occurring with some species, such as catfish. Given the size of the mixing zone, no significant adverse effects will occur with the established community of organisms in this portion of the river. The mixing zone will not otherwise impair designated uses of the St. Johns River. The treated effluent will not create a nuisance condition or violate any other DER standards that apply within the mixing zone. With the advent of the full scale facility, maximum, average and chronic toxicity criteria can be reasonably expected to be met at the point of discharge, within the mixing zone and at the boundary of the mixing zone. As described before, the effects of sediment transport upon discharge are localized. The proposal for a mixing zone takes into account Rule 17-4.244, Florida Administrative Code, in the sense of addressing present and future sources of pollutants and the combined effects with other pollutants or substances which may be present in the ambient waters. One of the concerns which DER has about wastewater is the effect which that pollutant has on organisms within the environment. To gain an impression of that influence, testing is required to establish whether the wastewater is acutely toxic. The testing is known as bioassay assessment. While this assessment is normally done after the grant of a construction permit, when confronted with uncertainty about the quality of the effluent, some testing is beneficial prior to the grant of a construction permit. This is especially true given DER's experiences in dealing with raw effluent of several of the scallop processors, to include Homer Smith, which showed that the raw effluent was acutely toxic. This acute toxicity testing is done by placing test organisms into aquaria containing the effluent and measuring survival of those species over time. Results are described in terms of a measurement of the concentration of the effluent at which 50 percent of the organisms are killed during a prescribed test period. In static testing the organisms are simply exposed to the effluent for the requisite period of time. By contrast, a static renewal test calls for the effluent to be replaced with another sample of the effluent at various intervals within the test period. Finally, a flow through bioassay test calls for a continuous stream of fresh effluent to be introduced in prescribed concentrations over the duration of the test. A bioassay assessment in the static condition was performed related to DAF pilot scale effluent that was collected on April 19, 1985. In this instance Daphnia magna were used as test organisms and demonstrated a survival rate of greater than 50 percent in a 100 percent concentration of effluent over a period of 96 hours in the setting of static and static renewal tests. That survival rate was also shown in lesser concentrations of effluent as well. The April 19, 1985, sample was also used in testing the response of Pimephales promelas. These test organisms did not survive either in the static or static renewal tests. While an hypothesis has been made that acute toxicity was experienced in this test organism attributable to build-ups of ammonia, which is greater with this type of organism than with the Daphnia, due to larger biomass which allows for a greater number of ammonia generating bacteria to be presented in the test aquaria and the fact that the Pimethales excrete more ammonia, these differences do not definitely explain why the Daphnia survived and the Pimephales did not. In the series of static renewal bioassays performed on the wastewater that was collected at the plant on April 29, 1985, and shipped to Lenox, Massachusetts, for bench scale treatment, the test organisms of both types failed to survive for 96 hours. It was discovered that during the course of the test period, levels of ammonia rose rapidly. Trace metals in the treated effluent are principally in the form of stable species, as opposed to free ions. These constituents standing alone are not likely to have caused the mortality in the test organisms. The effect of decomposition of the organic constituents in the waste stream is the most likely explanation of why the bioassays of pilot and bench scale treated effluent did not lead to a satisfactory result. Unionized ammonia, a by-product of organic decomposition, is found to be a principle player in the explanation of why the treated effluent was acutely toxic to the test organisms. The exact cause of toxicity has not been precisely identified. Given the complex nature of the effluent, other potentially toxic substances such as sulfides, amines, and other organic compounds could have contributed to the demise of the test organisms. Moreover, toxicity can increase with combinations of chemicals acting in a synergistic fashion, making their combined effects more devastating than the effect of any single substance. Having in mind the fact that ammonia is a major problem in the survival of test organisms subjected to a bioassay, the question becomes one of what may be done to remove ammonia. The production of ammonia in wastewater would depend upon the presence of bacteria. The proposed DAF system removes substantial numbers of bacteria, thereby limiting the possibility of ammonia build-up, if bacteria are not allowed to recolonize in some part of the system prior to discharge. As discussed before, reduction of bacterial activity can be achieved within the proposed treatment system. This is unlike the experience with the bench scale and pilot scale testing that was done on the effluent in which a substantial amount of time transpired before subjecting the test organisms to the effluent and in which a substantial amount of time transpired while the test organisms were being subjected to static and static renewal procedures with the same effluent. The time intervals contributed to the build- up of toxic levels of ammonia in the effluent. The system which is proposed in this instance can avoid the problem of time as it relates to the build-up of levels of ammonia. To further reduce the influence of retention of the waste product, flow through bioassay testing would be the most appropriate measurement of the survivability of the test organism in that it would be responding to real case conditions pertaining to the quality of effluent and its potential toxicity. Under these circumstances, it is reasonable to believe that in a flow through bioassay test of the full scale treatment system, the test organisms could survive. This determination is reached given the reduction in retention time compared to the bench and pilot scale testing, which reduces ammonia, with further ability to reduce ammonia by frequent removal of residual materials from the sludge drying bed and sump pit and taking into account basic improvements in treatment efficiency associated with the full scale system. In addition, the pH of the effluent can be regulated to avoid toxicity in the ammonia which is associated with inappropriate balance within the pH. While a 96-hour LC-50 cannot be calculated with the results of bench scale and pilot scale testing, a reasonable possibility exists for the establishment of that measurement with the advent of a flow through bioassay. There is sufficient similarity between the effluent in the pilot and bench scale testing and the expected effluent in the full-size system for the bioassay testing that was done in those limited systems to give a meaningful indication of the probability that the Applicant can pass a flow through bioassay. Applicant can be reasonably expected to produce an effluent in the mixing zone which will not exceed the 96 hour LC-50 for acute toxicity. As with the circumstance of ammonia, pH can be controlled within the system to address the implications of changes in pH as it pertains to other pollutants in the wastewater. Ammonia production can be influenced by the amount of alkalinity in the effluent and the receiving waters. Alkalinity has not been measured thus far. Alkalinity could be established for the effluent and receiving waters and dealt with if it was suspected as being an explanation of problems with the build up of ammonia which might exceed DER standards. The discharge from the Applicant's plant will not cause long-term problems with low DO, high nutrients, algal imbalances, and chronic toxicity. Outside the Mixing Zone Those constituents within the waste stream, to include those for which a mixing zone was sought, will comply with applicable water quality standards at the boundary of the mixing zone. The dissolved oxygen deficit at its maximum can be expected to be in the neighborhood of 0.1 mg/L and will be exerted somewhere in the range between 1 and 2.5 km downstream of the point of discharge across the width of the plume in worst case conditions. This deficit is not of a dimension which is easily detectable. The implications of that deficit are difficult to perceive in terms of tangible environmental consequences. While a deficit in the range of 0.1 mg/L has some relevance in the DER permitting decision, that deficit as it is dispersed is not expected to cause or contribute to violations of water quality standards in the main channel of the river or in the inshore and embayment areas. While it is true that there are periodic fluctuations of dissolved oxygen below 5 mg/L, DER, as a matter of present policy and professional judgment believes that in this system which evidences characteristics of a clean well-flushed, unstratified water body occasional readings of low DO are not regarded as an indication of violation of water quality standards. This speaks to the main channel area of the river where the only quantifiable influence is expected. The facts presented in this case support the soundness of this policy choice. Petitioners presented the testimony of former officials within DER, namely Parks and Young, who stated that dissolved oxygen standards of 5 mg/L are applied at all times and at all places. They felt that the DER policy was to the effect that permits would not be granted for discharge in any circumstance where the DO concentrations are substandard in the ambient waters, regardless of the amount of decrease or deficit that would be promoted. Parks spoke of the availability of site specific alternative criteria, variances, exceptions or exemptions from the terms of the water quality rule. Having considered these remarks, the present DER policy of allowing the permit to be granted in the instance where occasional violations of ambient water quality standards related to 5 mg/L occur, in the face of the small deficit which is involved in this case, is the better choice. Further, it is a choice that is not so inconsistent with prior practices as to be arbitrary in nature. Finally, DER's position that it would be unadvisable to require a request for site specific alternative criteria, variances, exceptions or exemptions in circumstances such as this case is accepted, when taking into account the problems which would be presented to the agency in administering the permit program, should each Applicant who is confronted with occasional violations below standards for dissolved oxygen have to seek extraordinary relief. While the facts do identify that some pollutants can reach the embayment areas on the eastern shore, the facts do not depict a circumstance in which the amount and quality of that effluent will be such that it will cause or contribute to dissolved oxygen violations in those areas. The water quality in the embayment areas is lower than that in the main area of the river due to inadequate flushing. The areas inshore do not interact with the main channel in a way that would take advantage of the faster moving currents found in the main channel as this interaction might promote a better quality of water. In view of the situation in the embayment areas, the Applicant, on advice of his consultants, moved the proposed location of the discharge into the main channel away from the areas which were under greater stress in terms of dissolved oxygen values and in doing so avoided damage to these areas. The current velocities in the area east of the main channel are weak. There is a substantial distance from the point of discharge to the inshore areas. As the effluent moves toward the inshore or nearshore areas it will become so diluted it will not have an adverse influence on dissolved oxygen. Not only the distances involved, but also the fact that water flowing near the surface is well aerated contributes to the dilution of the effluent as it approaches the shore. Although it has been shown that some stress in the grasses along the eastern shoreline has occurred and the existence of blue-green algae has been shown, together with indications of undesirable algal production, the nutrients which are part of the effluent at the point of discharge are not expected to cause an imbalance in the natural populations of flora and fauna or create nuisance conditions or violations of transparency standards. The nitrogen increase could cause an increase in algal production in the order of one percent, which is inconsequential. The treated effluent will not adversely effect biological integrity of the St. Johns River. The benthic microinvertebrate community in this part of the river is fairly low density due to the fluctuations in salinity levels and predation by fish and blue crabs and given the nature of this substrate which is unstable with low levels of dissolved oxygen. The organisms that are predominant have a tolerance to siltation and fluctuations in dissolved oxygen. The treated effluent will not adversely effect the microinvertebrate community. Petitioners point out the fact that when DO concentrations decrease below optimum levels, fish and other organisms suffer. The fish reduce their movement, feeding and reproduction and they are less disease resistant. They are placed in a position of having to leave the area or risk death if the impacts of the decrease in dissolved oxygen are severe. The influence of the effluent at the point of discharge in this project is not expected to have significant impact on fish and other organisms within these topics of concern expressed in the paragraph. Even though the dissolved oxygen deficit extends in amounts below 0.1 mg/L as far as 2.1 km upstream and 4.5 km downstream and within a wide breadth of the center portion of the river, those deficits will not be significant to the water quality. The BOD associated with the discharge, allowing for mixing will not depress dissolved oxygen levels below DER standards of 5 mg/L. The combination of BOD and nutrient discharge will not cause an imbalance of algal production in the river, nor will it contribute to the dominance of nuisance algal species. The BOD nutrient loading associated with the discharge into the St. Johns will not promote significant ecological impacts on the St. Johns River, to include the possibility of more frequent and severe algae blooms, increase in benthic oxygen demand, risk of increase eutrophication, destruction of grass beds or decline in the fishery. With the advent of discharge in the St. Johns DO fluctuations in the river will not be greater nor will there be an occurrence of a swing from substandard dissolved oxygen levels to supersaturated dissolved oxygen. While the discharge from the Applicant's plant contains pollutants such as cadmium, zinc, arsenic, copper and organic decomposition products, the treatment provided the wastewater is expected to overcome any acute toxicity associated with these materials individually or in combination. Chronic toxicity is not expected related to these materials. The effects of these materials are not expected to cause physiological and behavioral responses which are abnormal in organisms such as reduced locomotion and reproduction or increase susceptibility to diseases to include ulceration and increased mortality. Treatment contemplated and provision of a mixing zone will allow compliance with the standards related to cadmium. Reference has been made to a development known as St. Johns Harbor which is in the vicinity of the proposed discharge and can be expected to promote some pollution in Palmo Cove and the St. Johns River. Although St. Johns Harbor development is proceeding through stages of permit review, it does not appear that it has reached a place in which exact information about its implications as a pollution source can be set out. In discussing the St. Johns Harbor Development, Petitioners emphasized that this eventuality and other matters which deal with cumulative impact have not been satisfactorily addressed. There is no indication than any other substantial development or activity other that St. Johns Harbor is contemplated in this area associated with the permit review at hand. St. Johns Harbor eventually hopes to develop 3000 residential units. It has received the approval of the Northeast Florida Regional Planning Council for the initial phase of development. It has been reviewed by the Florida Fresh Water Game and Fish Commission. The developers are proceeding with the project to include the sale of lots. Nonetheless, that development has not reached the phase where its implications would form the basis of a denial of this project based upon the theory of cumulative impact. While Petitioners contend that stormwater runoff from the St. Johns Harbor project will be a problem, assuming an inadequacy in the design which that developer employs to deal with that matter, this eventuality is not expected based on a review on the facts presented. Reference is made to the Ulcer Disease Syndrome which fish in the St. Johns have suffered from. The principal area in which this event has occurred is north of the area expected to be influenced by this discharge. Nonetheless, diseased fish have been found in Palmo Cove. This Ulcer Disease Syndrome is caused by heavy metals and hydrocarbons, and these materials act in league. The advent of additional heavy metals and other pollutants, such as those being discharged from the Applicant's plant could cause further deterioration in the condition of fish suffering from Ulcer Disease Syndrome. Having considered the facts, this outcome is not expected. Ambient levels of 18 other pertinent pollution constituents in the vicinity of the point of discharge were ascertained by the Applicant's consultants on the basis of field observations and historical United States Geological Survey and Florida Game and Fresh Water Fish Commission data. This formed a basis of an assessment of average and worst case values. This information indicates compliance with those parameters for purposes of water quality standards at the point of discharge. Implementation of Construction Permit Permit Conditions Applicant's Exhibit A-10 is a copy of the DER intent to issue the construction permit. It sets forth seventeen specific permit conditions, and these conditions should be imposed in the permit. The following are additional conditions that should be set forth in the construction permit: The operation and maintenance manual required by original Condition 10 shall provide that the DAF treatment system be cleaned regularly with a mild chlorine solution and that the wastewater from this maintenance be placed in a vehicle and carried off the premises for disposal at an appropriate location. This wastewater from the cleanup shall not be discharged from the plant into state waters. The operation and maintenance manual shall provide that a dosage level of chlorine to clean the pipeline that will result in comp- liance with all water quality standards at the end of the pipeline be added to a fraction of fresh water used to flush the system at the cessation of discharges each day. DER must approve this dosage amount before it becomes part of the operation and maintenance manual. The operation and maintenance manual shall set forth a regular schedule for pumping the accumulated sludge or solid materials from the sump pit. The operation and maintenance manual shall provide that as much as 50 gallons per minute of fresh tapwater may be added to recycled wastewater for pressurization. Any discharge created with this addition may not exceed 250 gallons per minute. Any discharge created above 200 gallons per minute shall be consti- tuted only of tap water. Two machine scallop processing operations at the plant will be limited to an average of 18 hours per day and no more than 90 hours in a week. Monitoring in Trout Creek shall continue as specified in paragraph 17(E) of the Consent Order as long as discharges into Trout Creek continue. On each occasion when the DAF treatment system is in operation, the Applicant shall have a fully trained operator on site. The terms of the construction permit shall expire on December 31, 1986. The constructed pipeline shall be leak tested once a month from June to September and every other month during other months of the year. If a leak in the pipeline is detected it shall be repaired within 20 days and retested for leaks within 15 days thereafter. The carrying out of any leak testing and repairs shall hereunder shall be certified by a professional engineer. Pre-pipeline Operations Petitioners have pointed out the fact that when two or more pollutants are present, as in the instance of the effluent discharged by the Applicant's plant, those pollutants tend to act in a synergistio manner. That can exacerbate the circumstance where you find low dissolved oxygen. This is particularly a matter of concern when discussing Trout Creek. This is unlike the impacts of the discharge into the St. Johns River which are not expected to exceed standards or promote adverse effects. The implications of operation within Trout Creek to allow necessary permit review by DER and the State of Florida, Department of Natural Resources can be overcome once the discharge is withdrawn from Trout Creek and may be addressed by DER more immediately if the dissolved air flotation unit, after a reasonable period of adjustment, does not perform in the fashion that it appears to be capable of. In the instance of discharge into Trout Creek, the material discharged tends to remain in that area for a relatively long period in that the creek is small and has very little flow and poor flushing characteristics. DO levels will be depressed, the presence of a deficit in dissolved oxygen caused by the discharge from the DAF unit would increase the probability of fish kills when contrasted with a circumstance where there is no further deficit of dissolved oxygen. Given the explanation of why a fish kill occurred based upon the past use of fly bait by the Applicant and the fact that there is no indication of fly bait in the present plans, a fish kill in Trout Creek in the time of interim discharged does not seem probable. With the advent of discharge into Trout Creek, the possibility is enhanced for algae blooms and increased eutrophication. There would also be some accumulation of toxic substances. Additionally, there would be some influence on juvenile fish which are more sensitive to pollutants and the possibility exists that it could reach levels that are lethal to bass larvae and juvenile sports fish. The creek would lose some of its viability as a nursery and some fish would leave the creek. These events are not irreversible and can be reasonably remedied with the cessation of discharge into the creek. Moreover, as in the instance with the problem with fish kills, if some set of circumstances attributable to the discharge were to occur in such dimensions as to cause long term impacts in Trout Creek, DER could take action against the construction permit. Dissolved oxygen in Trout Creek can be below the 5 mg/L standard. Data of the E.S.E. group showed that at Highway 13 bridge, approximately fifty yards from the plant in December 1984 and January 1985, values were as low as 0.1 and 0.2 mg/L, and readings could be frequently below 2 mg/L at Highway 13. In April through June 1985, periodic surface dissolved oxygen concentrations were in the range of 3 mg/L and as low as 2.4 mg/L. DO concentrations generally found at the bottom of Trout Creek could be as little or lower than 1 mg/L at times. In July 24, 1985, at the time when the plant had not been operating for approximately a month, the DO concentrations were 2.9 mg/L at mid-depth and 0.8 mg at the bottom. Within Trout Creek in the area of the Pacetti marina, Consultant White measured DO concentrations in the range 1-3 mg/L. On August 10, 1985, six weeks after operations had stopped at the Smith facility, DO concentrations were found to be 3 mg at the surface, less at mid-depth and 0 near the bottom. Computer modeling was not done to ascertain the impacts of a discharge directly into Trout Creek from the DAF unit. The modeling done by the Petitioner's consultant, Parks, using some of the concepts considered in the Applicant's modeling for the St. Johns River is inapplicable to the circumstances in Trout Creek. Trout Creek has also served as a nursing ground for reproduction and habitat for young fish. During the course of the operations by the Applicant in the discharge of essentially untreated effluent, the beds of bass and sun fish have not been seen within the creek. Water quality improves with the DAF unit and sediment loading by heavy metals decreases. Trout Creek is a stressed system at present. It has low levels of dissolved oxygen, high nutrient concentrations and the presence of heavy metals in undesirable amounts. The low numbers of pytoplankton species give some indication of a highly stressed ecosystem. The present officials of DER, Palmer, Owen and Fox, expressed their concerns about dissolved oxygen in those instances where there would be a decrease in ambient DO concentrations. This has particular importance in discussing the problems associated with the discharge into Trout Creek, as opposed to the point of discharge contemplated in the St. Johns River, which risk is minimized given the characteristics of that area and the higher readings of ambient dissolved oxygen in that water, as contrasted with low readings within Trout Creek. A literal interpretation of the position of the agency officials would lead to the conclusion suggested by the Petitioners that no discharge should be allowed into Trout Creek, even on an interim basis. However, such a position would be inherently unfair considering the fact that some discharge would occur into the creek before the installation of the pipeline, whether based upon simultaneous permit review by DER and the State of Florida, Department of Natural Resources in the easement case or sequential review as is contemplated in this instance. Admittedly, the amount of time involved in the discharge into Trout Creek increases in view of the severance of the easement case from the present proceedings. This circumstance occurred in view of the desire on the part of the DNR to see the actual treatment efficiencies involved with the dissolved air flotation unit as opposed to the theoretical possibilities of that equipment. In the present situation, it would be a reasonable policy choice for DER to allow an interim discharge into Trout Creek pending the opportunity for DNR to monitor the quality of the effluent produced by the DAF unit and make a decision about the easement, thus allowing installation of the pipeline if the easement is granted. This arrangement contemplates that DER should closely monitor the quality of the effluent produced by the DAF unit, to make certain, after the Applicant has been given the opportunity to make necessary adjustments to that unit, that the Applicant is not allowed to continue to discharge into Trout Creek following this period of adjustment, when it is shown that the Applicant's equipment is not performing as expected. In any event, the discharge of effluent into Trout Creek will continue over a limited period of time and the system can be expected to quickly return to its healthier state after the removal of the discharge from Trout Creek. This has occurred in the past when the operations of the plant ceased and occurred at a time when the wastewater was of a more damaging quality than contemplated by that associated with the DAF unit. In summary, it would be a reasonable policy choice to allow the interim discharge into Trout Creek on this occasion. Dredge and Fill Permit Characteristics of Pipeline Corridor The pipeline corridor encompasses portions of Trout Creek, Palmo Cove and the St. Johns River. The bottom sediments where the pipeline is to be installed are constituted of soft, and sometimes extremely soft, flocculent silt. Although these sediments are easily resuspended, dispersement of these sediments will only occur while the pipeline is being installed. In placing the pipeline, it is the intention of the Applicant to simply allow the pipe to sink into the sediment. The soft substrate is several feet deep in some places within the proposed corridor. Nonetheless, the pipe is expected to stabilize as it sinks into the material. There are places within the corridor where a crusty material may be found on the surface of or just beneath the substrate. These are locations where jetting or mechanical excavation may be necessary. Jetting may also be necessary along the approximately 155 foot stretch of the corridor that crosses the State of Florida, Department of Transportation right-of-way. This requirement would occur in view of the fact that the Department of Transportation mandates that the pipeline be at a minimum of 30 inches below the creek bottom. In those instances where jetting or other mechanical excavation might be utilized, silt screens would be used to control the short term turbidity. In the areas within the pipeline corridor where tree trunks and branches have been found, these obstructions can be removed without incident. Taking into account the nature of the substrate, at the location where the diffuser will be placed at the end of the pipeline, special attention will be given to that installation to avoid having the diffuser settle into the soft silty material. Given the fact that the silty material is several feet deep and the related fact that the Applicant has not done specific testing of the depth, density and compressibility of this silty material, careful attention should be given to anchoring the diffuser and making certain that the exhaust ports within that device are correctly positioned. The need for this close attention is borne out by the fact that a test pipe which was placed in the silty material settled approximately two and a half feet within several weeks. The matter of the security of the diffuser is also critical, given the fact that the diffuser will be located within one foot of the bottom. Through proper installation, the Applicant can avoid having the diffuser settle into the silty material over time. The installation techniques satisfactorily address the potential problems. Projected Impacts (1) Environmental The icthyological and macroinvertebrate communities within the pipeline corridor have been examined by the Applicant in the person of his consultants. It was found that there are a variety of freshwater fishes within Trout Creek, such as large-mouth bass and sun fish, and a moderate density of macroinvertebrates. The St. Johns River proper is dominated by estuarine and marine aquatic organisms. Infaunal macroinvertebrate densities in the area of the pipeline corridor in the St. Johns River are not high. In placing the pipeline, the effects on aquatic and benthic communities within the corridor or upon water quality do not pose a threat to those communities or to water quality. During the installation of the pipeline, some disturbance of the benthic organisms can be expected; however, those organisms will be able to recolonize quickly. The mere presence of the pipeline is not expected to cause long-term impacts on biological resources or water quality. (b) Navigation In the area of the intended placement of the pipeline related to Trout Creek, boating clubs utilize that vicinity for purposes of anchorage. Those clubs have as many as twenty to thirty boats whose size varies from twenty to fifty-five feet in length. Some of those boats carry anchors which can weigh forty-five pounds or more. Typically, in anchoring one of these craft, the anchor rope is tied down and the engines reversed to set the anchor. Although testimony was given to the effect that the anchors being set might puncture the pipeline, given the explanation about the placement of the pipeline and the nature of the pipe itself, problems with puncturing the pipeline as it might interfere with navigation or environmental concerns such as turbidity plumes due to a puncture of the pipeline are not expected. Nor are the activities associated with retrieval of the anchors via the use of electric winches or hoists seen to be a problem in the sense of snagging the pipeline and rupturing the pipeline when the anchors are brought aboard the vessels. In summary, the pipeline will not be an interference to navigation in the sense of boat anchorage or other aspects of navigation associated with boating. Moreover, the Applicant is willing to indicate the location of the pipeline on navigational charts to assist boaters in avoiding potential problems with anchorage. This is a desirable arrangement and should be done. Comparison of Projected Impacts with Statutory and Regulatory Criteria The dredge and fill activities associated with the pipeline are not expected to cause long-term or short-term adverse impact on biological resources or water quality, or are they expected to interfere with the conservation of natural resources or marine productivity or interfere with navigation to such an extent to be contrary to public interest. The placement of the pipeline will not promote unacceptable interference with fish and other natural resources or destroy clam beds or grass flats, such as would be contrary to the public interest. Permit Conditions Appropriate permit conditions are as follows: Installation of the pipeline shall be conducted within Trout Creek only during weekdays. Pipeline installation activities within Trout Creek shall not block navigation. The pipeline shall be constructed within 60 days following the receipt of all necessary approval, to include the grant of an easement by the State of Florida, Department of Natural Resources for the placement of the pipeline over submerged sovereignty lands. All conditions set forth in the DER draft permit. See Applicant's Exhibit A-57.
Findings Of Fact The City has brought this action pursuant to Section 120.56, Florida Statutes, challenging Rules 17-50.015(2)(f) and 17-50.016(2)(f), Florida Administrative Code. Section 120.56(1), Florida Statutes, authorizes any person substantially affected by a rule to seek an administrative determination of the invalidity of the rule on the ground that the rule is an invalid exercise of delegated legislative authority. The Department has stipulated to the City's standing to maintain this action. 4. Rules 17-50.015(2)(f) and 17-50.016(2)(f) were adopted by the Department pursuant to Sections 403.061, 403.101, 403.1823, 403.1832, 403.1838 and 403.804, Florida Statutes. No disputed issues of material fact exist between the parties.
The Issue Whether Petitioner should be granted a water pollution operation permit for the Bennett Road Sewage Treatment Facility under Chapter 403, Florida Statutes.
Findings Of Fact Petitioner owns and operates a sewage treatment plant known as the Bennett Road Sewage Treatment Facility in Orlando, Florida. The plant was originally built in the 1950's and its method of treatment has been modified and improved over the years. At the present time, the plant serves about 60 percent of the sewage treatment needs of the city. The sewage is first treated for the removal of biological compounds by means of trickling filters, followed by chemical treatment for removal of BOD, suspended solids, and phosphorus. In the latter process, aluminum sulfate is used, together with a polymer to assist in forming larger particles for more rapid settlement. These processes are followed by final settling, clorination and discharge through an outfall pipe approximately five miles to the Crane Strand Creek and thence to the Little Econlockhatchee River (Little Econ) which meets the Big Econlockhatchee River approximately twelve miles downstream and flows into the St. Johns River twenty- seven miles downstream. About 60 percent of the flow from Crane Strand Creek into the Little Econ is derived from the Bennett Road plant and there is no other significant source of pollutants from the remainder of the discharge. (Testimony of Jewett, Matthes, Petitioner's Composite Exhibits 1,2) In 1973, Respondent's predecessor, the State Department of Air and Water Pollution Control, issued a temporary operation permit to Petitioner, subject to certain conditions, for the Bennett Road plant. The permit was effective until June 1, 1976, "or sooner pursuant to the permittee upgrading his facility to provide 90 percent treatment and obtaining an operation permit in accordance with the rules and regulations of the Department Of Pollution Control." On May 7, 1976, Petitioner submitted an application for an operation permit wherein it was stated that the facility would be abandoned as soon as the Orlando Easterly Regional Facilities were constructed with a new treatment plant to be located in the vicinity of Iron Bridge Road. Respondent's manager of the St. Johns River District advised Petitioner by letter of July 21, 1976, of the Department's intent to deny the application for an operating permit. The reasons given were that (1) available data was insufficient to show sustained secondary treatment as defined in Chapter 403, Florida Statutes, and Chapter 17- 3, Florida Administrative Code; and (2) the facility's discharge caused violation of Section 17-3.09(3), F.A.C. The latter provision establishes one of the criteria for classification of Class III waters and provides generally that the concentration of dissolved oxygen in all such surface waters shall not average less than 5 mg/l in a twenty-four hour period and never less than 4 mg/l. Class III waters are designated in Rule 17-3.09 as "Recreation - propagation and management of fish and wildlife." In its above-mentioned letter, Respondent suggested that the Petitioner apply for a temporary operation permit. Petitioner chose to request an administrative hearing on the proposed denial and did so by petition filed herein on August 5, 1976. At the commencement of the hearing, the parties orally stipulated that Petitioner has been meeting the statutory and regulatory requirements as to secondary treatment so as to warrant withdrawal of Respondent's objection to granting the permit on that ground. The parties also agreed that the only matter remaining in issue is the question of whether Petitioner's discharge violates water quality criteria. (Petitioner's Exhibits 6,7) Petitioner began consideration of the need to replace or expand the Bennett Road plant about 1968. These plans have reached a stage where the Petitioner is now in the process of purchasing land and concluding a planning study required under federal law to construct a regional facility to service the eastern part of Orlando and a few of the northerly communities, including some in Seminole County. Such regionalization of sewage treatment facilities is encouraged by the federal government which provides 75 percent of the funding necessary for construction under Public Law 92-500 . It is anticipated that the proposed facility will be completed in 1980 at which time the Bennett Road plant will cease operations. The regional facility is to be located at Iron Bridge Road and its discharge would flow into the Little Econ several miles downstream of the present Bennett Road discharge. (Testimony of Matthes, Schneider, Petitioner's Composite Exhibit 2) Operation permits have been granted from 1971 to 1976 to a number of sewage treatment plants that will tie-in to the proposed regional facility. These permits were issued even though the discharge of most of the plants did not meet water quality standards. However, practically no secondary treatment plant can meet water quality standards in Central Florida without an extensive mathematical "modeling." These calculations made by Respondent are formulated from surveys of the body of water in question and result in what is termed "a waste load allocation." This term deals with a treatment standard that is computed to ascertain the assimilative capacity of a receiving body of water to take in pollutants from a particular source in order that water quality standards in terms of dissolved oxygen levels may be maintained. The waste load allocation is the standard which the treatment from the source must perform before it can be discharged. None of the above-mentioned plants nor the Bennett Road plant had been provided an assigned waste load allocation at the time of Respondent's adverse action on Petitioner's application. Neither had it been a past requirement of Respondent to require information concerning dissolved oxygen from an applicant in order to issue an operation permit. However, a preliminary survey of the Little Econ had been completed by Respondent by February 1976, and from this, a mathematical model was later computed based on chemical analysis of water samples taken from designated areas in that body of water. In the aforesaid permits that were granted, a clause provided that the plants would have to work with the City of Orlando in resolving discharge problems and cooperate in the achievement of a regional system. Although water quality criteria had not changed in recent years, they had not been enforced because Respondent had had insufficient background water data. At the time Petitioner's permit application was recommended for denial, the primary basis therefor was the fact that the Bennett Road plant had not then reached 90 percent treatment capability over a sustained period. The question of water quality was incidental in view of the fact that that office did not then have the final determination of water quality as evidenced by the intensive survey of the Little Econ and the final math modeling. (Testimony of Jewett, Davenport; Petitioner's Exhibit 4) By interoffice memorandums from the Respondent's Director of the Division of Environmental Permitting to district and subdistrict managers, dated January 28 and April 13, 1976, Subject: Temporary Operating Permits, the said managers were instructed that no operating permits should be issued for any source not achieving secondary treatment of its wastes or not meeting water quality standards. In such cases, only temporary operating permits were to be issued. Further, it was stated in the April 13 memorandum that enforcement action would be initiated against municipal facilities if they were either not achieving 90 percent removal Of BOD and suspended solids or not meeting water quality requirements, and had either (1) not applied for a federal grant, (2) was not following up to ensure receipt of the grant, or (3) had received a federal grant but was not expeditiously accomplishing the grant requirements. It was stipulated at the hearing that the memorandums had not been promulgated as rules by Respondent under Chapter 120, F.S. (Respondent's Exhibits 1, 2, Stipulation) Although the Little Econ is a highly degraded body of water, upstream of the Bennett Road discharge point it has a dissolved oxygen level of over 6 mg/l. After mixture with the Bennett Road discharge, the level drops to about 2 1/2 mg/l. Based upon the intensive survey taken by the Respondent in 1976, it was determined that water quality violations existed below the Bennett Road plant's discharge point but not above that point. It was further determined that the Bennett Road facility was contributing about 89 percent of the oxygen demanding substances in the system. In fact, the dissolved oxygen levels downstream from the Bennett Road discharge reached as low as one milligram per liter at several points. They ranged from that level up to approximately four and one-half milligrams per liter throughout the entire 27 miles of the system. The foregoing was the conclusion of Respondent's environmental specialist based on field data taken on August 30, 1976, at a time of the day when the dissolved oxygen levels would be at their highest. However, the drop in dissolved oxygen level to an even greater extent at certain points occurs in Respondent's mathematical model prediction that does not take into account any discharge from the Bennett Road plant. In fact, in such a "no discharge" situation, Respondent's prediction is that the dissolved oxygen level at points immediately following several control structures in the waters will produce an even greater drop than with the Bennett Road discharge taken into consideration. Although the control structures do not affect the actual oxygen demand on the system, they do increase the residence time of the water and permit substances to settle out. However, when the water flows over the dam, it creates reaeration that increases the oxygen level again. Therefore, although the control structures aggravate the problem, the Bennett Road discharge is in turn further aggravating the situation because some of the pollutants continue downstream. Part of the problem is due to the effect of deposits already on the bottom of the system and it is unknown to what extent they would be eliminated if the Bennett Road facility were taken out of the system. Although it is not anticipated that there would be a great rise in dissolved oxygen levels if the Bennett Road plant discharge were to be discontinued, Respondent's experts are of the opinion that there would be a definite increase in dissolved oxygen levels overall. Further, the field data and model predictions were based on high flow conditions but the 89 percent figure for pollutants from the Bennett Road facility was based on a low flow condition where it would be of more significance. Although the field data showed that at no point in the 27 mile course did the dissolved oxygen level of the water reach state standards of 5.0 milligrams per liter dissolved oxygen for Class III waters, the model prediction with no discharge from the Bennett Road facility shows that the dissolved oxygen level still would not meet state standards under high flow conditions. Under low flow conditions, though, the dissolved oxygen level without discharge from the Bennett Road plant would reach the state standards roughly halfway down the system. High flow conditions are more representative of an average of dissolved oxygen level during the year than under low flow conditions. The Bennett Road plant contributes approximately 60 percent of the total water flow reaching the St. Johns River. Even if the plant were to achieve advanced waste treatment standards, it still would not meet water quality standards. No evidence was presented as to the possibility of Petitioner using alternative methods of waste disposal, such as deep well injection, land irrigation, or the use of lakes and ponds. In fact, no discharge from the Bennett Road plant could be such as to raise the entire stream to meet the state requirement of 5.0 milligram per liter dissolved oxygen. (Testimony of Sawicki, Davenport, Armstrong, Horvath, Brown, Petitioner's Composite Exhibit 2, Respondent's Exhibit 3) An interoffice memorandum of Respondent's Grants section, dated October 28, 1976, pointed out that enforcement action had been shown to be a "great motivator in the area of bringing awareness to governmental agencies of their responsibilities in the field of pollution abatement." The memorandum sought compliance investigations of the various governmental entities within the area where the proposed regional sewage treatment system for East Orlando was to be undertaken, with recommendations that enforcement action be taken in the case of any violations of state standards. The memorandum further stated that enforcement action was already underway against the City of Orlando. The author of the memorandum denied that it was an attempt to force Respondent to proceed more vigorously with the regional system. (Testimony of Schneider, Petitioner's Exhibit 5) The Orange County Pollution Control Board requires variances from its rule that no treated effluent shall be discharged into the surface waters of the county. The Bennett Road plant operates under such a variance and at the present time is meeting county standards for sewage treatment. On May 19, 1976, the Orange County Assistant Pollution Control Director advised Respondent that the Bennett Road plant was meeting current state performance requirements and recommended approval of the operation permit. Although the county maintains records of the Little Econ River at various points, it has not used a mathematical model to determine whether the Bennett Road plant causes water quality violations. (Testimony of Sawicki, Petitioner's Exhibit 3)
Recommendation That the application of Petitioner City of Orlando, Florida for a water pollution operation permit for the Bennett Road sewage treatment facility be denied. DONE and ENTERED this 25th day of May, 1977, in Tallahassee, Florida. THOMAS C.

The Issue Whether Petitioner North Fort Myers Homeowners Association, Inc. (Homeowners) participated in DOAH Case No. 91-6436 for an improper purpose.
Findings Of Fact On September 11, 1991, Homeowners filed its Petition for Administrative Hearing and Request to Consolidate with Administrative Hearing set for November 7, 1991. The Petition alleged that Homeowners' interests would be adversely affected by Bradley's request for a permit for construction of a wastewater collection system that it planned to connect to Florida Cities Water Company's Sewage Treatment Plant. It was further alleged that Florida Cities current violations of federal water quality standards would increase as a result of such a connection. Bradley responded to the Petition by filing a Motion to Dismiss for failure to State a Claim/Or in the Alternative Motion for Summary Judgment. On October 31, 1991, Hearing Officer Quattlebaum granted Bradley's Motion to Dismiss for Failure to State a Claim. The Hearing Officer found that the Petition did not allege that the application for a wastewater collection system permit failed to comply with the agency's relevant rules and criteria. The Hearing Officer also ruled that the Petition did not identify when such criteria would be unmet by the project. Homeowners was given leave of ten days to file an Amended Petition. Homeowners timely filed its Amended Petition for Administrative Hearing on November 13, 1991. This Amended Petition continued to focus upon whether Bradley's wastewater collection system should connect to Florida Cities Water Company's Sewage Treatment Plant and the federal water quality issue as it relates to discharge after treatment. After Bradley filed its Motion to Dismiss the Amended Petition and Homeowners replied, Hearing Officer Quattlebaum entered a Recommended Order of Dismissal on December 12, 1991. The basis for the recommendation was that Homeowners had "failed to allege that the application for permit failed to comply with the relevant criteria as set forth in statute and rule which govern issuance of the permit." The Temporary Operating Permit under which Florida Cities was operating expressly allowed Bradley's wastewater collection system to connect to the sewage treatment plant upon satisfaction of the Department's permitting requirements for such a collection system. Homeowners lost its opportunity to address whether such a connection was proper when it failed to timely challenge this Temporary Operating Permit. The only agency action subject to challenge in this case was whether Bradley's application to construct the wastewater collection system complied with the Department's permitting requirements for the system. Florida Cities anticipated actions were irrelevant to this particular proceeding because final agency action had already been taken on the question of whether the connection could take place. Throughout this proceeding, Homeowners failed to comprehend that it had waived its opportunity to pursue a challenge to the connection of Bradley's wastewater collection system to the sewage treatment plant when it did not timely challenge Florida Cities' Temporary Operating Permit. The Order granting Bradley's Motion to Dismiss dated October 31, 1991, did not affirmatively set forth that the connection issue could not be pursued in DOAH Case No. 91-6436. Homeowners' lack of comprehension on this issue remains evident in the Amended Petition, the Motion for Reconsideration filed after the Recommended Order of Dismissal, the Response to the Motion for Attorney's Fees and the testimony presented at hearing. Lack of comprehension is a neutral condition which neither proves nor disproves that the Petition and Amended Petition were filed for improper purposes, as defined by Subsection 120.59(6)(e), Florida Statutes. No direct evidence of Homeowners' participation in the proceeding for an improper purpose was established at hearing. The attorney for Homeowners at the time the Petition and Amended Petition were filed denied that Homeowners was motivated by an improper purpose. It was seeking to protect water quality in its locale and to assure the local sewer treatment system is adequate. There was no evidence presented as to whether Homeowners has participated in other such proceedings involving Bradley and the same project for an improper purpose.
Recommendation Based upon the foregoing, it is recommended that the Department enter a Supplemental Final Order denying Bradley's request for attorney's fees and costs as Homeowners did not participate in this proceeding for an improper purpose as defined by Subsection 120.59(6)(e), Florida Statutes. RECOMMENDED this 26th day of June, 1992, in Tallahassee, Leon County, Florida. VERONICA E.

The Issue Whether a septic tank permit, should be granted for lot 2, Whispering Oaks Subdivision. More specifically, does the' requirement of no more than four lots per acre require a minimum lot size of 1/4 acre? In the alternative, must the subject lot be grouped with three contiguous lots to determine whether the density requirement is met? If a permit should be denied, is a variance appropriate under HRS' rules and the circumstances of the case?
Findings Of Fact The essential facts in this case are uncontroverted. Ben F. Ward is the President and sole stockholder of Ben Ward, Incorporated. His business for over eighteen years has been real estate, construction and development. He has built over 300 homes and is familiar with the procedures for developing a subdivision, including obtaining septic tank permits. In 1979, Ben Ward purchased the property now designated Whispering Oaks Subdivision, located in the City of Oviedo, Seminole County, Florida. The property contains approximately six acres, net. That is, the paved right of ways have been disregarded. There are no streams, lakes or other bodies of surface water on the property. Ward subdivided his property into 26 lots, two of which, lots number 12 and 17, are dedicated for recreational use and will not have homes. Some of the lots are less than 1/4 acre; others are more. Lot number 2 has 9,137 square feet, 1,753 square feet less than 1/4 acre. As a condition of plat approval, the City of Oviedo required Ward to obtain approval from the Seminole County Health Department. Val Roberts was the county health officer with whom Ward consulted. A process was devised for "borrowing" acreage from lots of over 1/4 acre to meet the minimum requirements for lots less than 1/4 acre. In other words, it was determined that the total net acreage in the subdivision would be considered in computing the four lots per acre minimum. The plat was approved and was recorded in 1980. Between 1981 and 1987, 19 residences were built and septic tank permits were obtained. There is city water service in the subdivision. In 1985, Ward sold 16 lots to the Erie Land Company, a partnership comprised of Mary Ellen Hines and her husband. In reliance on the arrangement worked out with the health department, Ward assured ELC that the lots were buildable. He remained trustee of the property. On February 26, 1987, the Seminole County Health Department (HRS) denied Ward's application for a septic tank permit for lot number 2, including a 3-bedroom, 2-1/2-bath home, comprising 2100 square feet. The denial letter cites rule 10D-6.46(7)(b), F.A.C., and says "Four lots grouped together lack approximately 3000 square feet of meeting the required lot size...". The letter provides the procedure for petition for a variance to Rule 10D-6, F.A.C. Ward applied for the variance, and its approval was recommended by a vote of 3-2 by the HRS Review Group for Individual Sewage Disposal. The recommendation was denied by the HRS State Health Officer, E. Charlton Prather, M.D. in a letter dated May 7, 1987 which states, in pertinent part: Grouping of lots to determine whether the subdivision meets the four lot per acre requirement must be done in a logical manner to maximize the homogenous dissemination of sewage effluent or prevent a concentration of sewage effluent in a small or limited area. Once a specific area is utilized in calculating sewage flow dispersal for a group of lots, that area cannot be further used for another lot or group of lots. Lot number 2 meets all requirements of HRS for septic tanks, with the exception of the density methodology. Ward surveyed the homes built and occupied for approximately a year and found that the subdivision as a whole is about 60% of allowable capacity. Ms. Haynes has lived on lot number 22 for six years and has never had septic tank problems. She holds an inactive real estate license, and before purchasing the property found the subdivision high and dry and well-developed.
Recommendation Based on the foregoing, it is, hereby RECOMMENDED: That the application for septic tank permit for lot 2, Whispering Oaks subdivision, be GRANTED. DONE and RECOMMENDED this 18th day of February, 1988, in Tallahassee, Florida.

The Issue The issue for consideration in this case is whether Respondent should be disciplined, to include a three day suspension without pay, because of the misconduct alleged in the Notification of Suspension issued herein.
Findings Of Fact At all times pertinent to the issues herein, Respondent, William T. Mooney, worked as a laboratory technician for the City of Clearwater's Public Works/Water Pollution Control Division. On April 15, 1993, Doreen Spano, the City's utility lab supervisor, held a meeting of her division personnel at which she identified Iracema Drysdale as the lead worker and, in order to clarify any misconceptions among lab workers as to work deadlines, presented a policy letter for the lab, entitled "New Work Schedule". The schedule set guidelines and deadlines for the daily workload. The memorandum contains inconsistent statements, however. For example, while Ms. Spano indicated both in the memo and at hearing that the instructions therein are merely guidelines, she also used such imperatives as "must" and "will" in the memo. Specifically, the memorandum indicates the daily plant BOD must be in the incubator by 12:00 PM, and the daily plant bacteria must be in the incubator by 12:30 PM. Respondent has worked in this City laboratory for approximately 14 years. During this time he has developed a method of accomplishing his tasks which is described by Ms. Drysdale as less than efficient. She indicates he frequently misses his time deadlines and works at his own pace. Respondent, on the other hand, claims he has always completed his tasks according to the Standard Methods Manual, but, due to the time the samples are received in the lab, could not accomplish both the BOD and the bacteria procedures within the guidelines set in that manual and the Environmental Protection Agency standards manual. Either one or both would be late. This controversy, much of which was made by both sides, is, in reality, only peripherally related to the issue in controversy here which is whether Respondent was insubordinate or not on September 9, 1993. Both Ms. Drysdale and the Respondent signed the memorandum in question here indicating their receipt and understanding of the directions contained therein. Thereafter, on September 9, 1993, Ms. Drysdale entered the lab shortly before the lunch period to find the bacteria procedure not done and Respondent working on the BOD procedure. It appears that the bacteria sample was taken at 6:00 AM on this day and, under EPA guidelines, had to be preserved in the incubator within six hours or the results of the procedure would be invalid and not eligible for reporting to the EPA. When Ms. Drysdale asked Respondent why he was doing the BOD when the bacteria procedure had not been accomplished, he indicated that Ms. Spano's memorandum required the BOD to be done by 12:00 noon and the bacteria not until 12:30 PM. He considered this a directive and indicated he would complete his work consistent therewith. Again, there is a contradiction in the testimony as to the nature of the conversation between Ms. Drysdale and the Respondent. Ms. Drysdale asserts that about noon on the day in question, she suggested to Respondent that he start the bacteria procedure first and then do the BOD procedure. Respondent refused because he believed he had to follow the new work schedule prepared by Ms. Spano. Ms. Drysdale then told him to do the bacteria procedure first and she would assume the responsibility. Respondent still refused and, raising his voice to her, completed the BOD procedure. When he finished that, he did the bacteria procedure but by that time, the sample was too old and had to be discarded. Respondent's recounting of the incident is somewhat different. He claims he was approached by Ms. Drysdale who asked him why he did the bacteria procedure after the BOD procedure. When he pointed out the dictates of the memorandum, she claimed to know nothing about it even though her signature, along with that of Respondent and Mr. Olson, appears on the bottom thereof. Nonetheless, according to Respondent, Ms. Drysdale said she would check on it. After lunch, according to Respondent, Ms. Drysdale came back with the Standard Methods book. When he showed her the new work rules, he claims, she admitted she was aware that Ms. Spano had written them. When he asked her what Ms. Spano had said about the situation, she allegedly replied, "Why don't you do it the way I say and if Doreen (Ms. Spano) asks, I'll take the responsibility." Respondent was upset because, he contends, things like this always happen. Respondent, in subsequent testimony, denied ever getting a direct order from Ms. Drysdale or that she indicated she would assume responsibility. On balance, while there is little doubt in Ms. Drysdale's testimony as to what happened, Respondent tells two different stories regarding the conversation. At one point he claims she asked him why he didn't do it her way and that if he did, she'd assume responsibility. At another, he claims she merely asked why he was doing the procedures as he was and made no mention of assuming responsibility. It is clear that Ms. Drysdale wanted the bacteria procedure done first, and while she might not have couched her request in directory language, there can be little doubt she communicated her desires to Respondent, albeit in a perhaps more gentle manner. In any case, she was Respondent's supervisor and he knew it. She wanted the work done as she indicated and her request, made under the authority she had to get the work done as she desired, had the force and effect of a direct order which Respondent disobeyed at his peril. Ms. Spano indicated she discussed not only the appointment of Ms. Drysdale as lead worker at the April 15, 1993 meeting, but also the six hour requirement for specimens. Respondent denies this, but it is found he knew exactly what the requirements were. He claims he has been doing things the way the memorandum calls for ever since it was promulgated and this is not inconsistent with his current position on doing the BOD procedure first. When this incident took place, Mr. Reckenwald, the superintendent of the water and pollution control division, and the overall supervisor of the laboratory operation in question, received a recommendation for discipline, primarily because of Respondent's failure to follow orders. In addition, however, the incident created a problem for the City which has to report to the EPA and other federal agencies. Because of this report requirement, it is imperative the work be done properly. If it is not done properly, the work is worthless and may result in sanction action against the city by federal regulatory agencies. Not the least of concerns, also, is the public health consideration since effluent, the source of samples for both BOD and bacteria procedures, is discharged into the public waterways. On the basis of the above, a recommendations was made that Respondent receive a three day suspension. This is consistent with disciplinary guidelines contained in the City's Guidelines For Disciplinary Action. Respondent appealed the action to the City Manager who reviewed his submittal but nonetheless upheld the disciplinary action proposed.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is, therefore: RECOMMENDED that the City of Clearwater take final action in this matter to consist of suspension of the Respondent without pay for three days and imposition of 40 disciplinary action points. RECOMMENDED this 24th day of May, 1994, in Tallahassee, Florida. ARNOLD H.

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)
Findings Of Fact The County is a political subdivision of the State of Florida, and the Hillsborough County Sheriff's Office is a department of the County government. On or about January 18, 1989, a site evaluation for the County's application, on behalf of the Hillsborough County Sheriff's Department, for an onsite sewage disposal system (septic tank and drainfield) at Vandenberg Airport was conducted. A soil profile was prepared showing brown sand from the ground surface down 14 inches, a gray sand down another 2 inches, and a gray clay from 16 inches to 7 feet below the surface. The United States Department of Agriculture Soils Survey Book classifies the soils found at Vandenberg Airport as Manatee fine sandy loam, which is now called Chobee 10, and characterizes its permeability as "severe" with a seasonal high water table of from 0 inches at ground surface to 10 inches below the ground surface. By letter dated April 13, 1989, the Department formally denied the County's application due to the poor texture of the Chobee 10 soil and high water table found in the site evaluation, as well as the zoning of the property. This denial letter recognized the applicant's right to apply for a variance. Since the County anticipated denial of its application due to verbal indications from Departmental representatives, the County filed an application for variance with the Department on or about March 29, 1989. A Variance Review Board met and considered the County's variance application, and then recommended approval. However, the variance application was denied by the Department on June 1, 1989, due to the nature of the activities to be conducted on the site, as well as the severe soil conditions on site. The denial of the County's variance request effectively denied its application for this permit. The County has timely sought this review of the Department's denial of its application for a permit for a septic tank and drainfield system at Vandenberg Airport for use by the Sheriff's Department. The parties stipulated that the County's application included the redesign plans and report of its consulting engineers. They further stipulated that the location for which this permit is sought is imperative to the duties of the Sheriff's Department, and there is no alternative to this location without greatly increasing the response time of the Sheriff's Department to emergencies and other calls for service. The Hillsborough County Sheriff's Department has been operating its aviation unit out of a hangar at Vandenberg Airport for several years, and in March, 1989, the County entered into a ten year lease with the Hillsborough County Aviation Authority for approximately 103,126 square feet of land (2.37 acres) located at the Vandenberg Airport for a new hangar for storage and maintenance of aircraft used in conjunction with the services provided by the Sheriff's aviation unit. The site was formerly used for three residences which were served by septic tanks. This lease specifically provides that the County is responsible for obtaining all necessary permits and for securing necessary utility services for the use of this Sheriff's hangar. Thus, the Aviation Authority is not responsible for providing sewage treatment facilities for this site. The Hillsborough County Aviation Authority is not a unit within Hillsborough County government, but is an independent entity established by Special Act. The County has no control or authority over the Aviation Authority's creation of development plans, but the County may approve or disapprove these plans after they have been created by the Aviation Authority and submitted to the County. The Authority's development plans for expansion of Vandenberg Airport provide for runway expansion, taxiways, aprons and parking for aircraft and hangar expansion. As part of this expansion, the Aviation Authority has removed 51 individual septic tanks from homes located on lands which have been acquired, and which now comprise part of Vandenberg Airport. There is no record of any problems with the three residential septic tanks formerly located on this site for 25 to 30 years. The Aviation Authority's plans do not include construction of a sewage treatment plant or providing sewage treatment services in any manner other than with septic tanks, the permits for which must be obtained by its lessees. No centralized wastewater service is available to the proposed Sheriff's hangar at the Vandenberg Airport, and the closest sewer main will be more than 10,000 feet away upon its completion in 1990. The County's five year capital improvement plan does not include extension of this sewer line to the Airport. The location for the Sheriff's hangar is currently zoned SPI-AP-V, which is a special airport district zoning classification created in September, 1989, for Vandenberg Airport. In this zoning district, manufacturing, processing and assembly activities are prohibited. Retail activities are also prohibited, as well as hotels, motels, repair services, physician and dental offices, bus and train terminals, lumberyards, warehouses, publishing and printing, and rental and leasing activities. This district is to be used for public use facilities, wastewater treatment plants and lift stations, aircraft landing fields, airport and airport related activities. "Airport" activities are defined to include fuel storage and transmission facilities, hangars, aircraft service, repair and maintenance facilities. "Airport related" activities are defined as: Uses which are dependent upon proximity to the airport for effective performance, or which provide services to the airport..., including but not limited to airport maintenance facilities and associated administrative offices; sales of new and used aircraft and aircraft parts; sales of aircraft fuels, lubricants, and other aircraft supplies; ... and other airport-related uses compatible with the operation of airports for public and private use. Based upon five soil borings taken at the boundaries of, as well as within, the proposed hangar site, Darrell Hanecki, a geotechnical engineer who was accepted as an expert in engineering, found that the groundwater table was 3 to 4 feet below the existing ground surface in October and November, 1988. The seasonal high groundwater table was estimated to be approximately 12 inches above the existing ground water table at that time, but significant fluctuations in the groundwater level were anticipated due to seasonal variations in rainfall, runoff, and other site specific factors. The borings upon which Hanecki's findings are based were performed in general compliance with accepted procedures for standard field penetration tests. Hanecki concluded that the soil conditions are suitable for the proposed hangar if constructed on a shallow footing foundation with special site preparations. William Fernandez, who was accepted as an expert in civil engineering, developed a redesign of the County's septic tank and drainfield in support of its variance request in order to address concerns expressed by the Department's representatives concerning soil conditions on site. It is proposed that the septic tank and drainfield site will be excavated to a depth of 6 feet, and all clays will be removed. The site will then be backfilled with clean materials in order to allow the drainfield to percolate through these clean materials from three mounded drains which will be located in a two foot high mound constructed above the original grade. A pump will be used to lift the effluent from the tank to the drainfield. The septic tank will have a 750 gallon capacity. It is projected that 8 people will use this septic tank each day, and that each person will cause 25 gallons of sewage per day to be deposited in the system, or a total of 160 gallons of sewage per day. Only domestic wastes from the hangar restrooms will go into the system. Oils, greases and other substances used in aircraft maintenance and repair will be separated and carried to a retention pond through a system of trenches. After hearing the testimony of the County's expert witnesses about the surface water management system to be constructed on site, the Department's environmental specialist, Gary Schneider, testified that he was no longer as concerned about the possibility of oils, greases and other hazardous materials getting into the septic tank system. The County has also applied to the Southwest Florida Water Management District for a surface water management permit, and must receive that permit for this proposed hangar at Vandenberg Airport. The Department seeks to rebut the expert testimony offered by the county primarily with the testimony of Robert Blanco, supervisor of the county health department's septic tank permit program, who was neither tendered nor accepted as an expert, as well as a letter from Richard Ford, resource soil scientist with the Soil Conservation Service, dated September 18, 1989, who took one soil boring and concluded that the soil identified was poorly drained to very poorly drained Chobee loamy sand. Ford was not present to testify. Blanco agreed with Ford's conclusion, expressed in his letter, that the seasonal high water table on this site will come to the surface, or within 10 inches of the surface, for 2 to 6 months each year, causing ponding to occur. Based upon the demeanor and qualifications of the witnesses who testified at hearing, it is specifically found that the testimony offered in support of the County's application, and in particular the expert testimony of Hanecki and Fernandez, is more credible and is given greater weight than the testimony offered on behalf of the Department, particularly the testimony of Blanco. Blanco was not qualified or tendered as an expert in any field, and therefore, he was only competent to offer fact testimony. He speculated, without any supporting evidence in the record, that the septic tanks formerly on this site were not built to Code specifications and probably did not work, although there is no evidence of any complaints about these septic tanks during the 25 to 30 years they were in operation. Blanco also insisted that standardized texts describing soil types over large geographic areas are more reliable than actual soil borings on site, although he could not render an expert opinion in this regard. The letter from Ford offered by the Department was not supported by other competent, substantial, credible evidence, and in any event was based upon only one soil boring as opposed to five borings conducted by Hanecki in accordance with generally accepted practices. Therefore, it is found that the groundwater table on this site is 3 to 4 feet below the existing ground surface, and the seasonal high groundwater table is approximately 12 inches above the existing groundwater table, although it does fluctuate. It was undisputed at hearing that the soils on site are Chobee 10, which is poorly to very poorly drained soil, but the County's redesign of the proposed septic tank and drainfield reasonably and adequately accounts for, and accommodates, this condition by excavating to a depth of 6 feet and backfilling with clean materials, and by placing three drains in a mounded drainfield built two feet above the existing ground level. This redesign complies with the requirements and provisions of Chapter 10D-6, Florida Administrative Code.
Recommendation Based upon the foregoing, it is recommended that the Department enter a Final Order granting the application of Hillsborough County for a permit for an onsite sewage disposal system (septic tank and drainfield) for the Sheriff's Department hangar at Vandenberg Airport.

The Issue Whether the proposed Florida Administrative Code Rules 28-20.110, 28-20.120, and 28-18.210 are invalid exercises of delegated legislative authority.
Findings Of Fact Parties Petitioner, Florida Keys Citizens Coalition, Inc. ("FKCC"), is a non-profit Florida corporation whose address is 10800 Overseas Highway, Marathon, Florida 33050. The primary purpose of FKCC is to "protect the quality of life of the citizens of the Florida Keys." The primary emphasis of the organization involves issues related to the carrying capacity, the limits of the infrastructure, and the environmental qualities of the Florida Keys. Consistent with its purpose, FKCC opposes regulations which it believes will diminish the quality of the natural habitat in Monroe County and the City of Marathon and hinder safe and efficient emergency evacuation. FKCC has been involved in previous Monroe County litigation, including participating as a party to at least two formal administrative challenges to the 2010 Monroe County Comprehensive Plan (Monroe County Comprehensive Plan). Petitioner, Last Stand, Inc., is a non-profit Florida corporation whose address is Post Office Box 146, Key West, Florida 33041-0146. The primary purpose of Last Stand is to preserve and protect the quality of life in the City of Key West, the Florida Keys, and their environs, with particular emphasis on the natural environment. To that end, Last Stand opposes regulations that it believes diminishes the quality of the natural habitat in the Florida Keys and regulations that hinder safe and efficient emergency evacuation in the Florida Keys. Last Stand is an organizational member of FKCC. Moreover, many individual members of Last Stand are also members of FKCC. A substantial number of members of both FKCC and Last Stand live, work, and/or engage in various recreational activities in the City of Marathon or in nearby areas. For example, a substantial number of members of both of those organizations regularly use and enjoy the nearshore waters of Monroe County for recreational water activities, such as boating, diving, snorkeling, and/or swimming.3 A substantial number of members of both organizations also regularly use and enjoy terrestrial habitats in Monroe County, including the City of Marathon, for recreational activities such as hiking and bird-watching. A substantial number of the members of both FKCC and Last Stand may be adversely affected or impacted by the issues which are in dispute in this proceeding. Moreover, the issues in this proceeding are germane to the purposes of both FKCC and Last Stand. Also, both FKCC and Last Stand regularly represent their members' interests in formal administrative hearings and local commission meetings relative to environmental and growth management issues. Respondent, Administration Commission, consists of the Governor and Cabinet and is empowered to adopt, by rule, any enactment, amendment, or rescission of a land development regulation or element of a local comprehensive plan in the Florida Keys area. Respondent, Monroe County, is a local county government within the Florida Keys Area of Critical State Concern ("ACSC"). Respondent, City of Marathon, is a municipality within the Florida Keys ACSC. Intervenor, the DCA, is the state land planning agency responsible for the general supervision of the administration and enforcement of the ACSC program. As the state planning agency, the DCA is authorized to propose changes to local comprehensive plans and land development regulations within an ACSC for adoption by the Administration Commission. Economic Base of Florida Keys Tourism is the economic base of the Florida Keys. Moreover, the basis for the Florida Keys' tourism is a healthy natural environment that supports fishing, diving, water sports, boating, bird-watching habitat, visiting endangered species habitat, and other related activities. History of the Florida Keys ACSC The Florida Keys area is designated as an ACSC and consists of, unincorporated, Monroe County, the City of Layton, the City of Key Colony Beach, the Village of Islamorada, and the City of Marathon. See § 380.0552(3), Fla. Stat. (2004).4 The City of Key West has been separately designated as an ACSC pursuant to Florida Administrative Code Rule Chapter 28-36. The Florida Keys were originally designated by the Administration Commission in 1975 and re-designated by the Legislature in 1986. The legislative intent section and the Principles for Guiding Development, as set forth in Subsections 380.0552(2) and (7), Florida Statutes, together require an effective land use management system that protects the natural environment and character of the Florida Keys, maintains acceptable water quality conditions, ensures adequate public facility capacity and services, provides adequate affordable housing, supports a sound economic base, protects constitutional property rights, and requires adequate emergency and post- disaster planning to ensure public safety. During the past 20 years, the growth management process has been implemented in essentially two phases. The first phase involved developing, adopting, and implementing the first comprehensive plans and regulations under the new designation. These plans and regulations were adopted by the county and cities in the mid-1980s. The 1986 plan established a growth management system that substantially increased protection of natural resources and began to reduce the over-allocation of density in the Florida Keys. It also achieved the long-term protection of North Key Largo. However, several major problems were not adequately addressed by the 1986 plan, including maintaining evacuation capability, water quality protection, sewage treatment, stormwater treatment, and community character. In addition, although the plan required a focal point plan for Big Pine Key, this planning process did not result in a viable plan that adequately protected the Florida Keys deer. The required open space ratios proved difficult to maintain within habitats once development occurred, resulting in fragmentation of habitat. The second phase involved the planning process undertaken in the early 1990s to meet the requirements of the Growth Management Act and to update the plan based on lessons learned in implementing the 1986 plan. In developing, reviewing, and litigating the Monroe County Comprehensive Plan, the following critical issues emerged involving how to: maintain acceptable hurricane evacuation capability; retrofit existing development and provide new development with adequate wastewater and storm water facilities, including, where appropriate, upgrading of on-site systems; determine the carrying capacity of the Keys to withstand the impacts of additional land development and modify state and local plans, regulations and programs so that the carrying capacity is not exceeded; provide an adequate supply of affordable housing while maintaining acceptable hurricane evacuation and protecting the environment. In 1996, the Administration Commission adopted a rule which included a cap of 255 residential units per year for Monroe County. The rule also adopted a five-year Work Program into the Monroe County Comprehensive Plan with the local governments to construct sewage treatment facilities, replace cesspits, and purchase land to protect natural habitat. Monroe County, the City of Marathon, and the DCA were required to submit reports to the Administration Commission each year "documenting the degree to which the Work Program objectives for that year [had] been achieved." The rule contemplated that if the local governments did not make "substantial progress" towards accomplishing the tasks of the Work Program, the unit cap for new residential permits would be reduced by at least 20 percent for the following year. The Administration Commission found a lack of "substantial progress" in 1999 and adopted a rule which reduced the annual allocation of residential permits by 20 percent and extended the five-year Work Program to seven years. The Administration Commission found "substantial progress" had been accomplished in 2001 and began rulemaking to restore the permit allocation. However, the rule was challenged, and since the Administration Commission found a lack of "substantial progress" in 2002, the Commission adopted a revised rule which did not restore permits. The Carrying Capacity Study The 1996 Administration Commission rule amended the Monroe County Comprehensive Plan to require the completion of a carrying capacity analysis. The carrying capacity analysis shall be designed to determine the ability of the Florida Keys ecosystem, and the various segments thereof, to withstand all impacts of additional land development activities. The analysis shall be based upon the findings adopted by the Administration Commission on December 12, 1995, or more recent data that may become available in the course of the study, and shall be based upon the benchmarks of, and all adverse impacts to, the Keys land and water natural systems, in addition to the impact of nutrients on marine resources. The carrying capacity analysis shall consider aesthetic, socioeconomic (including sustainable tourism), quality of life and community character issues, including the concentration of population, the amount of open space, diversity of habitats, and species richness. The analysis shall reflect the interconnected nature of the Florida Keys' natural systems, but may consider and analyze the carrying capacity of specific islands or groups of islands and specific ecosystems or habitats, including distinct parts of the Keys' marine system. (Ref. 1991 Stip. Settlement Agreement). Agencies: County, DCA, DEP, DOH, DOT, GFC, SFWMD, NMS, SFRPC, EPA, USFWS, Army COE, and other interested parties to include representatives of environmental organizations and development interests. The Florida Keys Carrying Capacity Study ("FKCCS") was completed over a period of six years. Six million dollars was allocated by the DCA and the United States Army Corps of Engineers to produce the Monroe County Sanitary Wastewater Master Plan, the Stormwater Management Plan, and the FKCCS. The contractor, URS Corporation, completed the FKCCS and the Carrying Capacity/Impact Assessment Model ("CCIAM"), a separate component to be used in forecasting land use scenarios. A panel of external experts was used to peer review the scope of work. In September 2002, the study was completed. The National Research Council of the National Academy of Sciences ("Council") reviewed the CCIAM and FKCCS and, as a result of its review, adjustments were made to the CCIAM. The Council's review concluded that overall, due to data constraints and other issues in certain portions of the CCIAM, the model proved insufficient to develop a comprehensive carrying capacity framework that would allow for undisputable determinations of whether future development scenarios fall within the carrying capacity of the Florida Keys. The marine module, the most data- deficient, was subsequently removed from the CCIAM. The FKCCS recommended four main guidelines for future development in the Florida Keys: Prevent encroachment into native habitat. A wealth of evidence shows that terrestrial habitats and species have been severely affected by development and further impacts would only exacerbate an already untenable condition. Continue and intensify existing programs. Many initiatives to improve environmental conditions and quality of life exist in the Florida Keys. They include land acquisition programs, the wastewater and stormwater master plans, ongoing research and management activities in the Florida Keys National Marine Sanctuary, and restoration efforts throughout the Florida Keys. If further development is to occur, focus on redevelopment and infill. Opportunities for additional growth with small, potentially acceptable, additional environmental impacts may occur in areas ripe for redevelopment or already disturbed. Increase efforts to manage the resources. Habitat management efforts in the Keys could increase to effectively preserve and improve the ecological values of remaining terrestrial ecosystems. Partnership Agreement While preparing the Assessment Report for 2003, the DCA Secretary concluded that the existing policy direction, consisting of imposition of the Work Program by the Administration Commission and reduction of residential permits, due to lack of substantial progress, was not sufficient to solve the problems facing the Florida Keys. The Assessment Report described difficulties and delays in implementing the Work Program. Most of the sewage treatment facilities contemplated by the Work Program were not constructed and valuable upland habitat continued to be developed. On December 16, 2003, the Administration Commission concluded that Monroe County had not made substantial progress and directed the DCA "to determine changes that would be necessary to the comprehensive plan to fully implement the requirements of the Work Program[,] as well as habitat protection provisions." The Administration Commission also accepted the staff recommendation that it "determine substantial progress has been made for the City of Marathon, and that some permits will be provided back to the City of Marathon," the number to be determined at the Administration Commission's January 27, 2004, meeting. The DCA approached the Florida Keys local governments and community-based organizations and proposed a Partnership Agreement to "begin implementation of the Work Program associated with the Florida Keys Protection Act." The DCA Secretary addressed the governing boards of the Florida Keys' local governments concerning the proposed Partnership Agreement. Monroe County, the City of Marathon, and the Village of Islamorada adopted resolutions supporting the partnership proposal. By letter dated February 25, 2004, the DCA Secretary requested that the Governor, as a member of the Administration Commission, authorize the Administration Commission staff to initiate rulemaking to amend the Comprehensive Plans of Monroe County and the City of Marathon. According to the letter, this action was requested based upon a series of significant commitments made by each of these local governments which addressed issues related to habitat protection, affordable housing, wastewater and stormwater management projects, land acquisition, and nutrient credits. The letter also noted the following: A complete follow-through on these commitments would mean over $410 million would be spent in the coming years to address these issues in the Florida Keys. Habitat protection will be increased, environmentally-sensitive hammock and pinelands would be purchased, new wastewater and stormwater management projects would be initiated, and 230 units of affordable housing would be made available for residents of the Florida Keys. * * * In essence, we have developed proposals that allow additional units primarily for affordable housing in the Florida Keys, but also would ensure the most pressing issues will be jointly addressed by local and state government. Consistent with the February 25, 2004, letter, the Partnership Agreement consists of commitments by the Florida Keys' local governments and several state agencies to address habitat protection, wastewater and stormwater treatment, affordable housing, and hurricane evacuation. At its March 9, 2004, meeting, the Administration Commission accepted the DCA's recommendation to initiate rulemaking to implement the Partnership Agreement. The Proposed Rules 29. Proposed Rules 28-18.210, 28-20.110, and 28-20.120 were published in the Florida Administrative Weekly on July 16, 2004.5 According to the published notice, the purpose of Proposed Rule 28-18.210 is to amend Policy 101.2.14 of the Marathon Comprehensive Plan to address building permit allocations by increasing the annual residential permitting cap and specifying allocations authorized for market rate and affordable housing, restoring certain allocations authorized for market rate and affordable housing, authorizing certain unused rate of growth ordinance allocations to roll forward, and deleting the requirement for nutrient credits upon a date certain. The notice also provides that the Proposed Rule amends the Work Program set forth in Policy 101.2.14 of the Marathon Comprehensive Plan to establish Year Eight and Year Nine to address tasks not yet completed in the original Work Program. The published notice states that the purpose of Proposed Rules 28-20.110 and 28-20.120 is to amend Policy 101.2.13 of the Monroe County Comprehensive Plan to address building permit allocations by increasing the annual residential permitting cap and specifying allocations authorized for market rate and affordable housing, restoring certain allocations previously reduced to be targeted for affordable housing, authorizing certain unused rate of growth ordinance allocations to roll forward, and deleting the requirement for nutrient reduction credits upon a date certain. The notice also provides that the proposed rules amend the Work Program in Policy 101.2.13 of the Monroe County Comprehensive Plan to establish Work Program provisions for Year Eight, Year Nine, and Year Ten to address tasks not yet completed in the original Work Program. Finally, the notice states that the Proposed Rule amendments address the adoption of necessary land development regulations. The published notice cites Subsection 380.0552(9), Florida Statutes, as the specific authority for the Administration Commission's promulgating the Proposed Rules and Section 380.0552, Florida Statutes, as the law implemented. Petitioners challenge portions of Proposed Rule 28-18.210, which will amend the Marathon Comprehensive Plan and portions of Proposed Rules 28-20.110 and 28-20.120,6 which will amend the Monroe County Comprehensive Plan and the Monroe County Land Development Regulations on the basis that they constituted invalid exercises of delegated legislative authority. Petitioners contend that the proposed rules should comply with Section 380.0552 and Chapters 163 and 380, Florida Statutes, and, therefore, should be analyzed for such compliance in this proceeding. Notwithstanding Petitioners contention to the contrary, for the reason stated in paragraph 199 below, Proposed Rules 28-18.210, 28-20.110, and 28-20.120 will be analyzed based on their consistency with Section 380.0552, Florida Statutes, because that is the provision which the proposed rules explicitly purport to implement. The published notice does not specify the subsection of Section 380.0552, Florida Statutes, that the proposed rules implement. However, the parties agree that the proposed rules must be consistent with Subsection 380.0552(7), Florida Statutes, which set forth the Principles for Guiding Development. Restoration/Increase of ROGO Allocations The Comprehensive Plans for Monroe County and the City of Marathon include a Permit Allocation System, under which Monroe County was originally allocated 255 permits per year for new residential units. As noted in paragraph 18 above, in 1999, the Administration Commission determined that substantial progress on the Work Program had not been accomplished and adopted a rule reducing the annual allocation of permits by 20 percent. After the incorporation of the Village of Islamorada and Marathon, and a voluntary reduction by the Village of Islamorada, the current annual allocation of residential development permits is 158 for Monroe County, 24 for Marathon, and 14 for the Village of Islamorada. Proposed Rule 28-20.110(1) amends Policy 101.2.13 of the Monroe County Comprehensive Plan by increasing the annual unit cap of 158 to 197, thereby restoring the original level of permits issued for new residential development under the Rate of Growth Ordinance ("ROGO"). The proposed rule requires that "[e]ach year's ROGO allocation of 197 new units shall be split with a minimum of 71 units allocated for affordable housing in perpetuity and market rate allocations not to exceed 126 new units per year." Proposed Rule 28-18.210 amends Policy 101.2.14 of the Marathon Comprehensive Plan by increasing the maximum number of permits for new residential units from 24 to 30 per year, thereby, restoring the original level of permits per year for new residential development under ROGO. The proposed rule requires that "[e]ach year's ROGO allocation of 30 units shall consist of 24 market rate and 6 affordable units" and that the affordable housing "remain as affordable housing in perpetuity." In addition to restoring the number of permits for new development to the original levels, Proposed Rule 28-20.110 amends the Comprehensive Plans of Monroe County and Marathon to restore available permit allocations that were unused in previous years and to allow unused ROGO allocations to be allocated in subsequent years. Proposed Rule 28-20.110 adds a new provision to the Monroe County Comprehensive Plan, providing that "effective July 12, 2004, 140 ROGO allocations, which represent unused reductions for ROGO Years Nine through 12, and 25 units lost in Year Ten due to lack of nutrient credits, are reallocated to the County exclusively for affordable housing purposes." Proposed Rule 28-18.210 adds a provision to the Marathon Comprehensive Plan that "effective July 12, 2004, 65 ROGO allocations, which represent unused ROGO allocations for ROGO Years 9 through 12, are to be reallocated to the City exclusively for affordable housing." Advancing/Borrowing Nutrient Credits The existing Comprehensive Plans of Monroe County and the City of Marathon include a nutrient credit system. According to the Monroe County Comprehensive Plan, nutrient reduction credits are earned when existing treatment systems are upgraded. The amount of nutrient reduction credits earned correlate to the type of treatment system to which an old system is upgraded. Thus, if a treatment system is upgraded to the "best centralized system" or the "advanced wastewater treatment system," Monroe County would earn the most nutrient credits possible. For example, elimination of a cesspit by connection to a centralized advanced wastewater treatment system earns 1.5 nutrient credits, and the elimination of a substandard on-site disposal system by connection to a centralized secondary treatment system earns 0.5 nutrient credits. Under the existing Comprehensive Plans of Monroe County and the City of Marathon, development permits for new residential development can only be issued if a nutrient reduction credit has been earned. The requirement that adequate nutrient credits be earned prior to issuance of permits is to mitigate for nutrient impacts of new residential development. However, Proposed Rules 28-18.210 and 28-20.110 provide that Monroe County and the City of Marathon will be permitted to "borrow" nutrient credits from the pool of nutrient credits that are anticipated from the construction and/or completing of sewage treatment facilities. The existing Comprehensive Plans of Monroe County and the City of Marathon provide that nutrient reduction credits are earned by the construction of the Little Venice system according to the schedules prescribed in the Comprehensive Plans. The schedules in the Comprehensive Plans provide that "213 of the total credits estimated to be available from the full operation of the system shall be earned when the wastewater permit is issued, the design/build contract for the system has been fully executed and construction of the system has commenced." The Comprehensive Plans also provide that all the remaining available credits shall be earned when the construction of the Little Venice System is complete, the collection system lines have been installed, and the final total of credits available from the operation of the systems has been calculated. Proposed Rules 28-20.110 and 28-18.210 amend the Comprehensive Plans of Monroe County and Marathon by allowing 213 of the total credits estimated to be available from the full operation of the Little Venice system to be earned, effective July 13, 2003. The proposed rules also provide that when the Little Venice system is completed, "[t]he total credits available shall be reduced by the 213 [credits] advanced in the year 2003." Proposed Rule 28-20.110 amends the Monroe County Comprehensive Plan by allocating 41 nutrient credits for market rate units and 193 nutrient credits for affordable housing units to Monroe County. The Proposed Rule 28-20.110 provides that the 41 nutrient credits will be subtracted from the nutrient credits subsequently earned from hookups to the Key West Resort Utilities Wastewater Facility ("Key West Resort Utilities"). The 193 nutrient credits will be subtracted from hookups to the Key West Resort Utilities, Bay Point, and Key Largo Wastewater Facilities. Repeal of Nutrient Reduction Provision As described in paragraph 42 above, the existing Comprehensive Plans of Monroe County and the City of Marathon have mandatory nutrient provisions that require nutrient credits to be earned prior to issuance of a permit for new residential units. Proposed Rules 28-20.110 and 28-18.210 amend the Comprehensive Plans of Monroe County and the City of Marathon by repealing the mandatory nutrient credit provisions. Pursuant to the proposed rules, "effective July 13, 2005, no nutrient credits shall be required if the local government has made satisfactory progress as determined by the Administration Commission in meeting the deadlines established by the Work Program as adopted by rule after March 15, 2004." Challenges to Increase/Restoration of Permits, Advancing Nutrient Credits, and Repeal of Nutrient Reduction Provision Petitioners contend that the increase in new residential permits is arbitrary and capricious and contravenes the law implemented because it will increase development even though the identified thresholds for growth in the Florida Keys--water quality, terrestrial habitat, and evacuation times-- have been exceeded and will "worsen" the water quality. Petitioners challenge the provision which allows the borrowing or awarding of nutrient credits before wastewater projects are completed as arbitrary and capricious, because it will allow a net increase in the nutrient impacts into the nearshore waters of the Florida Keys and will "worsen" the water quality. Proposed Rules 28-20.110(1) and 28-18.210 increase the number of permits for new residential units from the preceding years. However, the number of permits to be issued under the Monroe County Comprehensive Plan has not increased. Rather, the permits will be issued in a shorter time frame and without being subject to the previous conditions. Even though increased development could result in an increase in the nutrient impacts into the nearshore waters of the Florida Keys, the adverse effect of such nutrient loading is offset by the adequate treatment of wastewater and stormwater runoff. To address the problem of nutrient loading, the Proposed Rules 28-20.110 and 28-18.210 extend the years of the Work Programs and include in those programs tasks, such as construction and completion of wastewater facilities, as well as financing for those projects. Based on the commitments of Monroe County and the City of Marathon in the Partnership Agreement, there is a reasonable expectation that the projects included in the Work Program of the Proposed Rules will be completed. When completed, the wastewater treatment facilities will provide nutrient credits. In anticipation of the completion of the wastewater treatment facilities, Proposed Rules 28-20.110 and 28-18.210 restore the annual permits for new residential units to their original levels and allow previous unused ROGO allocations to be allocated. The Proposed Rules provide that the nutrient credits for these allocations will be borrowed from the pool of nutrient credits that are anticipated from the planned construction and completion of wastewater facilities. Petitioners' contention that the repeal of the mandatory nutrient reduction credit provision is arbitrary and capricious and contravenes the law implemented because such repeal allows the water quality to worsen, is inconsistent with the "no net nutrient" provision of the Comprehensive Plans and is unjustified given that the nutrient pollution has increased since the nutrient credit provisions were adopted. Petitioners also contend that the repeal of the nutrient credit provision is arbitrary and capricious because the repeal is effective on a date certain without further action and without regard for whether it is justified. Proposed Rules 28-20.110 and 28.18-210 repeal the mandatory nutrient reduction credit provisions of the Comprehensive Plans, but the condition precedent to the repeal is the Administration Commission's making a determination that Monroe County and the City of Marathon have "made satisfactory progress . . . in meeting deadlines established by the [new] Work Program." This determination must be made prior to the repeal going into effect. Presumably, the tasks in the Work Program for which satisfactory progress must be made are those relevant and reasonably related to and which result in nutrient credits. Contrary to Petitioners' assertion, the repeal of the mandatory nutrient credit provision does not automatically become effective on the date prescribed in the proposed amendments. Instead, the repeal is contingent on Monroe County's and the City of Marathon's making "satisfactory progress." The term "satisfactory" is not vague as asserted by Petitioners. In the context of Proposed Rules 28-20.110 and 28-18.210, "satisfactory" would be given its common and ordinary meaning, which is "sufficient to meet a demand or requirement."7 Annual Reporting Requirement The existing Comprehensive Plans for Monroe County and the City of Marathon provide that "beginning September 30, 2003, and each year thereafter, [the respective local government] Monroe County and the [DCA] shall report to the Administration Commission documenting the degree to which the Work Program objectives have been achieved." Proposed Rules 28-20.110 and 28-18.210, will modify the annual reporting requirements in the Monroe County and Marathon Comprehensive Plans. The proposed amended provision, which is underlined, and the existing provision are as follows: Beginning September 30, 2003, and each year of the work program thereafter, Monroe County and the Department of Community Affairs shall report to the Administration Commission documenting the degree to which the work program objectives for that year have been achieved. The report for years seven and eight shall be combined and provided to the Administration Commission by September 30, 2005. The Commission shall consider the findings and recommendations provided in those reports and shall determine whether substantial progress has been achieved toward accomplishing the tasks of the work program. Petitioners contend that the proposed rules, which delete the requirement for Monroe County and for the City of Marathon to submit the September 2004 progress report to the Administration Commission, are arbitrary and capricious. Petitioners assert that by deleting the requirement for the 2004 annual progress report, the proposed rules fail to establish an annual safeguard that is required to ensure that the environmental conditions and infrastructure limitation that the annual Work Program is designed to resolve, do not worsen. The proposed rules delete the requirement that Monroe County and Marathon submit their respective reports in September 2004 and delay submission of that report by a year. The time spent negotiating the Partnership Agreement and the proposed changes to the Monroe County Comprehensive Plans and the Land Development Regulations left little time for Monroe County and the City of Marathon to implement the new Work Programs. Moreover, the DCA and the Administration Commission would have had too short a time period in which to judge whether Monroe County and Marathon had made substantial progress. By combining the reports for Years Seven and Eight of the Work Program, the Administration Commission can expect a meaningful report on Monroe County's and the City of Marathon's progress in implementing their respective Work Programs. Monroe County Work Program Under Proposed Rules Proposed Rule 28-20.110 amends the Work Program Policy 101.2.13 of the Monroe County Comprehensive Plan by adding Years Eight, Nine, and Ten to the existing Work Program. Many of the tasks included therein address and are related to wastewater facilities, habitat protection, affordable housing, and hurricane evacuation and implement the Partnership Agreement. Year Eight of the Work Program requires that Monroe County and other designated agencies perform the specified tasks and provide, in relevant part, the following: Year Eight (July 13, 2004 through July 12, 2005) Review and revise (as necessary) the Conservation and Natural Areas Map. Initiate acquisition strategy for lands identified outside the Conservation and Natural Areas identified as worthy of protection. Begin public hearings for Conservation and Natural Areas boundaries. Conclude public hearings for the adoption of the amended Conservation and Natural Areas Boundaries. Adopt an ordinance to implement a moratorium on ROGO/NROGO applications that involves the clearing of any portion of an upland tropical hardwood hammock or pinelands habitat contained in a tropical hardwood hammock or pinelands patch of two or more acres in size located within a Conservation and Natural Area. Adopt amendments to the comprehensive plan and land development regulations to enact overlay designations, and eliminate or revise the Habitat Evaluation Index, and modify the ROGO/NROGO system to guide development away from environmentally sensitive lands. Amend land development regulations to prohibit the designation of Conservation and Natural Areas (Tier 1) as a receiver site for ROGO exempt development from sender sites; and to further limit clearing of upland native habitat that may occur in the Natural Areas (Tier I) and the Transition and Sprawl Reduction Area (Tier II) upon designation by the County. Develop Land Acquisition and Management Master Plan and address both funding and management strategies. Provide $40 million in financing secured by infrastructure tax for wastewater facilities. Begin construction of wastewater plants or laying of collection lines for Baypoint, Conch Key and Key Largo Trailer Village/Key Largo Park. Ensure the connection for up to 1,350 EDUs [equivalent development units] at Stock Island to Key West Resort Utilities. Complete the Lower Keys and Key Largo feasibility study. Complete projects identified in the Storm Water Management Master Plan. Evaluate and implement strategies to ensure that affordable housing remains affordable in perpetuity for future generations. Establish a partnership with non-profit organizations in order to construct affordable housing using additional state funds. Identify potential acquisition sites for affordable housing proposals and include in the Land Acquisition Master Plan. Provide up to $10 million in bond financing from the Tourist Impact Tax for acquisition of land for workforce housing and affordable housing sites. Complete a comprehensive analysis of hurricane evacuation issues in the Florida Keys and develop strategies to reduce actual hurricane clearance times and, thereby, reduce potential loss of life from hurricanes. As discussed below, several of the tasks in Year Eight of the Work Program implement parts of Goal 105 of the Monroe County Comprehensive Plan. Goal 105 reads: Monroe County shall undertake a comprehensive land acquisition program and smart growth initiatives in conjunction with its Livable CommuniKeys Program in a manner that recognizes the finite capacity for new development in the Florida Keys by providing economic and housing opportunities for residents without compromising the biodiversity of the natural environment and the continued ability of the natural and man-made systems to sustain livable communities in the Florida Keys for future generations. Goal 105, also referred to as the "Smart Growth Goal," provides a framework to implement the FKCCS and a 20-year land acquisition program. The initial phase of implementing Goal 105 calls for the drafting and adoption of "Tier Maps" to be used as guidance for the Monroe County's Land Acquisition Program. Pursuant to Policy 105.2.1 of the Monroe County Comprehensive Plan, the Tier maps will designate and map properties into one of the following three general categories for purposes of Monroe County's Land Acquisition Program and the smart growth initiatives: Natural Area (Tier I); Transition and Sprawl Reduction Area (Tier II); and Infill Area (Tier III). Tier I property is property where all or a significant portion of the land is characterized as environmentally sensitive by policies of the Monroe County Comprehensive Plan and applicable habitat conservation plan. Tier I is to be designated as a Natural Area. New development is to be severely restricted in Tier I. Tier II is any geographic property where scattered groups and fragments of environmentally-sensitive lands, as defined by the Comprehensive Plan, may be found and where subdivisions are not predominantly developed. New development is to be discouraged in Tier II, which is to be designated as Transition and Sprawl Area. Tier III is property where a significant portion of land is not characterized as environmentally sensitive, as defined by the Monroe County Comprehensive Plan, where existing platted subdivisions are substantially developed, served by complete infrastructure facilities, within close proximity to established commercial areas or where a concentration of non-residential uses exist. New development and re-development are to be highly encouraged in Tier III, which is to be designated as Infill Area. Petitioners contend that Task A, which requires Monroe County to "review and revise [as necessary] the Conservation and Natural Areas ["CNA"] Map, vests unbridled discretion to the County to amend the CNA map without adequate standards or criteria." Further, Petitioners assert that Task A does not identify the purpose for which the CNA map is to be used. Based on this assertion, Petitioners contend that Task A is arbitrary and capricious and contravenes law. Task A will assist in the implementation of the Comprehensive Plan by requiring Monroe County to review and revise the CNA map. In reviewing Task A, it is clear that the county must adhere to the criteria prescribed in Goal 105 of the existing Monroe County Comprehensive Plan. When Task A is read together with Goal 105 and its related policies, it is clear that the purpose of Task A is to provide guidance for the Monroe County Land Acquisition Program. As a part of the review and revision process, the Partnership Agreement, which Task A implements, provides that the Monroe County staff should prepare the CNA map utilizing Florida Marine Source Resources Institute ADID maps, the most recent aerial photographs, site visits as necessary, and obtain input from DCA and the public. Moreover, when Task A is read with Task B, and other relevant parts of the Monroe County Comprehensive Plan, it is clear that a CNA map is to be used to implement Goal 105 of the Monroe County Comprehensive Plan, which is related to land acquisition and "smart growth initiatives." Petitioners assert that Task B, which requires Monroe County to "initiate acquisition strategy for lands identified outside the [CNA] boundaries," is arbitrary and capricious and contravenes the law implemented, because it provides no standards or criteria. Task B is consistent with Policy 105.2.1 of Goal 105 of the Monroe County Comprehensive Plan. The Partnership Agreement consistent with Goal 105 provides that Monroe County will identify lands outside the CNA boundaries for acquisition and target for purchase appropriate environmentally-sensitive lands that are contained within upland habitat of two acres or more outside the CNA. Task C requires Monroe County to "begin public hearings for [CNA]." Task D requires Monroe County to conclude the public hearings for adoption of the amended [CNA] boundaries. Petitioners contend that Tasks C and D are arbitrary and capricious and contravene the law implemented, because they do not require that an end result be achieved as a result of these public meetings. When the provisions of Task C and Task D are read together, with Goal 105 and the relevant provisions of the Partnership Agreement, it is clear that the end result sought as a result of the public hearings is to receive public comment regarding the identification of lands to be included in the CNA. Furthermore, this is a reasonable meaning of Tasks C and D in light of the well-known purpose of public hearings. Petitioners challenge Task E, which requires Monroe County to "adopt an ordinance to implement a moratorium on ROGO/NROGO applications that involves the clearing of any portion of an upland tropical hardwood hammock or pinelands habitat contained in a tropical hardwood hammock or pinelands patch of two or more acres in size located within a [CNA]." The purpose of the moratorium is to prevent impacts to native habitat until Monroe County adopts permanent regulations and amendments. Petitioners contend that Task E of Year Eight of the Work Program, which requires Monroe County to "adopt an ordinance to implement a moratorium on ROGO/NROGO applications that involve the clearing of any portion of an upland hardwood hammock or pinelands habitat contained in a tropical hardwood hammock or pinelands patch of two acres or more . . . within a [CNA]," is arbitrary and capricious and contravenes the law implemented. Petitioners assert that the criteria for the interim ordinance required fails to protect all hammock and pineland, does not protect enough hammock to ensure that the carrying capacity of the Florida Keys terrestrial habitat to sustain degradation and loss is not exceeded, does not require that the interim protections last until replaced by permanent ones, and does not apply to ROGO-exempt allocations. The criteria for the interim ordinance required by Task E is reasonable and will result in strengthening habitat protection in the areas specified in that provision. The fact that Task E authorizes the adoption of an ordinance that protects less than "all" hammock and pineland, does not make the proposed rule arbitrary and capricious, nor does the proposed rule contravene the law implemented. Petitioners contend that Task F, which requires Monroe County to "[a]dopt amendments to the comprehensive plan and land development regulations to enact overlay designations, and eliminate or revise the Habitat Evaluation Index ["HEI"], and modify the ROGO/NROGO system to guide development away from environmentally sensitive lands," is arbitrary and capricious and contravenes the law implemented. Petitioners claim that the standard set forth in Task F, "to guide development away from environmentally sensitive lands," is no more specific than is statutory language. Petitioners assert that the proposed rule should specify (1) habitat types, patch sizes and other characteristics of the areas to which regulations will apply, and (2) the exact nature of the regulation (i.e. a prohibition on direct or secondary impacts, the application of negative points or open space rations, etc.) that will be relied upon to guide development away from such areas. Task F requires Monroe County to adopt amendments to the Comprehensive Plan and Land Development Regulations to enact the overlay designations requiring Monroe County to implement Policy 105.2.2 of the Monroe County Comprehensive Plan. Task F will implement Goal 105 of the Monroe County Comprehensive Plan. This task will identify areas to which future development will be directed. Also, the overlay designations will give property owners more certainty with respect to whether they can or cannot develop their property. The requirement in Task F, that the HEI be reviewed or eliminated, is reasonable in light of Goal 105 of the Monroe County Comprehensive Plan. The HEI is currently used by Monroe County to evaluate the environmental sensitivity of land and its suitability for development and acquisition. The HEI requires lot-by-lot evaluations, which fail to take into account secondary impact of development and has resulted in the loss of valuable habitat. The Tier System in Goal 105 is designed to move Monroe County away from the existing HEI. Implementation of Goal 105 requires that the existing HEI be eliminated or revised. Task G of Year Eight of the Work Program requires Monroe County to "amend land development regulations to prohibit the designation of [CNA] (Tier 1) as a receiver site for ROGO exempt development from sender sites; and to further limit clearing of upland native habitat that may occur in the [CNA] (Tier I) and the Transition and Sprawl Reduction Area (Tier II) upon designation by the County." Petitioners contend that Task G is arbitrary and capricious and contravenes the law implemented because it fails to permanently protect even that habitat which Monroe County claims is most important to protect, allows the geographic scope of the contemplated rules to be defined in the future without stated criteria or standards, and allows an unnecessary delay in the adoption of protections which the data and legal requirements demonstrate should have been adopted two years earlier. Task G is intended to strengthen protection of habitat by adopting land development regulations to prohibit development in specified areas and to further limit clearing in designated areas. Goal 105, specifically, provides guidance as to the standards that such regulations must follow in Policy 105.2.1 of the Monroe County Comprehensive Plan. Petitioners contend that Task K of Year Eight of the Work Program requiring Monroe County to ensure the connection for up to 1,350 units at Stock Island to Key West Resort Utilities, is arbitrary and capricious and contravenes the law implemented. Petitioners charge that the requirement in the proposed rule is vague and could be met by simply connecting one home to the referenced wastewater utility to remedy a documented, serious water quality problem. When the purpose of Task K is considered, the reasonable meaning of the provision is that the task requires that Monroe County connect approximately 1,350 units to the designated facility. Petitioners contend that Task M of Year Eight of the Work Program, which requires Monroe County to "complete projects identified in the Stormwater Management Master Plan," is arbitrary and capricious and contravenes the law implemented. In support of this contention, Petitioners assert that the Proposed Rule does not identify the name or number of stormwater projects that are to be completed. Petitioners argue that by referring only to "projects," without specifying the name or number of the projects to be completed, the Proposed Rule may require that only a minimum of two projects be completed. The reasonable interpretation of Task M is that Monroe County is required to complete all the remaining projects identified in the Stormwater Management Master Plan. This meaning is supported by a review of related tasks in the previous years of the Work Program. For example, Year Six of the Work Program required Monroe County and other designated agencies to "initiate construction of selected projects as identified in the Stormwater Management Master Plan." Year Seven of the Work Program required that Monroe County and other agencies "continue implementing selected projects identified in the Stormwater Management Master Plan." Petitioners contend that Task P in Year Eight of the Work Program, which requires Monroe County to "provide up to $10 million in bond financing from the Tourist Impact Tax for acquisition of land for workforce housing and affordable housing sites," is arbitrary and capricious and contravenes the law implemented. As a basis for this contention, Petitioners claim that Task P sets a vague requirement which could be met by simply providing $1.00 in bond financing to provide a need which the State and Monroe County claim is important enough to justify the permitting increase allowed by Proposed Rules 28-18.210 and 28-20.110. Contrary to Petitioners' assertions, the requirement to provide $10 million in bond financing could not be met by providing $1.00 in bond financing. The $10 million figure represents the approximate amount of bond financing that will be provided. For the reasons stated above, it is not possible to include an exact amount in this Work Program requirement. The Work Program for Year Nine provides that the following tasks be done between July 13, 2005, through July 12, 2006: In coordination with the Florida Key Aquaduct Authority and Key Largo Sewer District, initiate the process to obtain $80 million in bond financing secured by connection fees. Secure site for lower Keys and Key Largo wastewater facilities. Petitioners contend that Task A for Year Nine for the Work Program, which requires that Monroe County, "in coordination with the Florida Keys Aqueduct Authority and the Key Largo Sewer District, initiate the process to obtain $80 million in bond financing secured by connection fees," is arbitrary and capricious and contravenes the law implemented. Petitioners contend that Task A, which requires that Monroe County only "initiate" the process necessary to obtain the required bond financing, and does not require that the funds be secured and dedicated to actual improvements, delays funding to remedy a critical water quality problem. The reasonable meaning of the provision in Task A, that Monroe County will initiate the process to obtain "80 million in bond financing secured by connection fees," is that Monroe County will take all steps legally necessary to accomplish obtaining the bond financing. Petitioners contend that Task B of Year Nine of the Work Program, which requires Monroe County to "secure a site for lower Keys and Key Largo wastewater facilities," is arbitrary and capricious and contravenes the law implemented, because it delays an important remedy to a critical water quality problem. Task B reasonably requires that one of the first steps that must be taken prior to constructing any wastewater facility is to secure a site. Irrespective of the need for the wastewater facilities specified in Task B, unless a site is secured, no construction can occur. Proposed Rule 28-20.110(1), which amends Policy of the Monroe County Comprehensive Plan by adding Year Ten to the Work Program, provides the following: Year Ten (July 13, 2006 through July 12, 2007) Award Contract for design, construction, and operation of lower Keys and Key Largo wastewater facilities. Begin construction of the lower Keys and Key Largo wastewater plants. Initiate connections to lower keys and Key Largo wastewater systems. Complete construction and hookups for Bay Point, Conch Key and Key Largo Trailer Village/Key Largo Park. Obtain $80M in bond financing secured by connection fees Petitioners contend that Task A, which requires Monroe County to award a contract for design, construction, and operation of the lower Florida Keys and Key Largo wastewater facilities, is arbitrary and capricious and contravenes the law implemented, because it delays an important remedy to a critical water quality problem. Petitioners also contend that Task D, which requires that construction and hookups for specified areas be completed, and Task E, which requires Monroe County to obtain $80 million in bond financing secured by connection fees, are arbitrary and capricious and contravene the law implemented. That Tasks A, D, and E are required to be completed in Year Ten of the Work Program, between July 13, 2006, and July 12, 2007, is reasonable in view of the steps that must be taken prior to completing the responsibilities provided in those tasks. Petitioners contend that Task B, which requires Monroe County to "begin construction of the lower Florida Keys and Key Largo Trailer Village/Key Largo Park wastewater plants" between July 13, 2006, and July 12, 2007, is arbitrary and capricious and contravenes the law implemented. Petitioners assert that this portion of Proposed Rule 28-20.110 delays an important remedy to a critical water quality problem and does not require the completion of construction or the hookup and operation of the necessary facility. Task B of the Work Program, to begin construction of the lower Florida Keys and Key Largo wastewater plants, reasonably and logically follows the task in the preceding work year that required Monroe County to secure a site for the lower Florida Keys and Key Largo wastewater facilities. Given this chronology, it is reasonable that Task B does not require that the specified wastewater facilities be completed and fully operational the same year that construction begins. Petitioners contend that Task C of Year Ten of the Work Program, which requires Monroe County and Largo Sewer District to "initiate connections to lower Keys and Key Largo wastewater systems," is arbitrary and capricious and contravenes the law implemented. As a basis for this contention, Petitioners assert that Task C does not require the completion of connections and operation of the system, but requires only the undefined "initiation" of connections. Task C, which requires Monroe County to "initiate connections" to the lower Florida Keys and Key Largo wastewater facilities, is not arbitrary and capricious. Given the purpose of this task, this provision reasonably requires Monroe County to begin connecting units to the wastewater facilities. Even without a precise number, the reviewing agencies can evaluate the Work Program for Year Ten, including Task C, and determine if Monroe County has made substantial progress. City of Marathon Work Program Under Proposed Rules Proposed Rule 28-18.210 adds Year Eight and Year Nine to the existing Work Program in Policy 101.2.14 of the Marathon Comprehensive Plan. The tasks in the Work Program, many of which implement the Partnership Agreement, include tasks related to the construction of wastewater facilities, affordable housing, and hurricane evacuation. Year Eight of the Work Program of the Marathon Comprehensive Plan include, in relevant, part the following tasks: Year Eight (July 12, 2004 through July 12, 2005) Begin construction of wastewater collection lines for Little Venice Phase II by December 2004. Work with the Florida Keys Aqueduct Authority to initiate bond financing for citywide sewer facilities and to develop a schedule of events necessary to initiate process by December 2004. Develop and advertise a Request for Proposal for the design, construction, operation of Marathon Central Wastewater System by December 2004. Obtain necessary bond financing (60% of projected sewer cost) secured by connection fees by December 2004. Award contract for design, construction and operation of Marathon Central Wastewater System by December 2004. By January 2005, identify potential acquisition sites for affordable work force housing. Establish a partnership with non- profit organizations in order to construct affordable housing using additional state funds. Evaluate strategies to increase the time that affordable housing remains affordable; establish a maximum sales price for work force housing and establish a ceiling on down payments that are not subsidized by public programs; and amend comprehensive plan and/or land development regulations. * * * Develop a map or list of real estate numbers of lots containing environmentally sensitive lands in need of acquisition and submit to the Department of Community Affairs by July 2004. Assist the state in land acquisition efforts by establishing a land acquisition advisory committee to prioritize proposed acquisitions by July 2004. Complete a comprehensive analysis of hurricane evacuation issues in the Florida Keys and develop strategies to reduce actual hurricane clearance times and thereby reduce potential loss of life from hurricanes. Year Nine of the Work Program of the Marathon Comprehensive Plan includes in relevant part the following tasks: Year Nine (July 13, 2005 through July 12, 2006) Begin construction of Phase I of Marathon Central Wastewater System by January 2006. Evaluate wastewater master plan and indicate areas, if any, that will not receive central sewer. For any area that will not be served by central sewer, develop a septic tank inspection program and begin implementation of the program by September 2005. * * * E. Develop and implement a Building Permit Allocation System that discourages and limits development in environmentally sensitive areas within the proposed Marathon comprehensive plan by July 2005. Petitioners contend that Proposed Rule 28-18.210(1), which establishes the Work Program for Years Eight and Nine, is arbitrary and capricious and contravenes the law implemented, because it fails to adopt regulation and plan changes, or requires same, to protect terrestrial habitat to the extent shown necessary in the Carrying Capacity Study. The mere fact that the proposed Work Plan for Years Eight and Nine of the Marathon Comprehensive Plan does not address habitat protection, does not make those provisions arbitrary or capricious. Neither does it mean that they contravene law. In this case, it reflects that the Work Plan emphasizes other issues relevant to the City of Marathon Comprehensive Plan. Siting Utilities and Public Facilities The siting of public facilities in Monroe County is governed by existing Policy 101.12.4 in the Monroe County Comprehensive Plan. According to that policy, Monroe County requires that an "analyses be undertaken prior to finalizing plans for the siting of any new or significant expansion (greater than 25 percent) of any existing public facility," and that the analyses include "an assessment of needs, evaluation of alternative sites and design alternatives for the selected sites and assessment of direct and secondary impacts on surrounding land uses and natural resources." With regard to the assessment impacts on surrounding land uses and natural resources, existing Policy 101.12.4 provides the following: The assessment of impacts on surrounding land uses and natural resources will evaluate the extent to which the proposed public facility involves public expenditures in the coastal high hazard area and within environmentally sensitive areas, including disturbed salt marsh and buttonwood wetlands, undisturbed beach berm areas, units of the coastal barrier resources system, undisturbed uplands (particularly high quality hammock and pinelands), habitats of species considered to be threatened or endangered by the state and/or federal governments, consistent with 105.2.1 offshore islands, and Conservation Land Protection Areas. Proposed Rule 28-20.110(2) amends existing Policy 101.12.4, which deletes the term "Conservation Land Protection Areas" from the category of areas included as environmentally sensitive areas, as quoted above, and replaces it with the term, "Natural Areas (Tier I)." Proposed Rule 28-20.110(2) also adds the following provision to existing Policy 101.12.4. Except for passive recreational facilities on publicly owned land, no new public community or utility facility other than water distribution and sewer collection lines or lift stations, and the existing Key Largo Wastewater Treatment Facility, shall be allowed within the Natural Areas (Tier I) unless it can be accomplished without clearing of hammock or pinelands. Exceptions to this requirement may be made to protect the public health, safety and welfare, if all the following criteria are met: No reasonable alternatives exist to the proposed location; and The proposed location is approved by a super-majority of the Board of County Commissioners. Petitioners contend that Proposed Rule 28-20.110(2), discussed above, is arbitrary and capricious and contravenes the law implemented. Petitioners assert that the Proposed Rule allows the siting of public facilities in terrestrial habitats (CNA or Tier I) and also allows water distribution and sewer collection lines or lift stations to be built as a matter of right in a CNA or Tier I, contrary to the findings of the Carrying Capacity Study. Petitioners also contend that the provision in the Proposed Rule, discussed above, is vague, because it refers to the term "natural areas," but is intended to mean CNAs. In the recent past, a decision to site a sewage treatment facility in an environmentally sensitive hammock elicited considerable controversy. Ultimately, Monroe County and the DCA agreed that public facilities should not be located on environmentally sensitive land. The proposed change to Policy 101.12.4 strengthens the policy by requiring approval of a super majority of the Monroe County Board of County Commissioners (County Commission) for an exemption. This also adds specificity to the policy and provides more protection for natural areas and, thus, improves protection of environmentally- sensitive habitat. Contrary to Petitioners' assertion, the term "natural area" is not vague. The Monroe County Comprehensive Plan currently includes Goal 105, which describes a detailed land classification system. "Natural Area (Tier I)" represents natural areas that can be targeted for acquisition and is an updated term. On the other hand, the term "Conservation Land Protection Areas" refers to lands targeted for acquisition by federal and state agencies. ROGO Exemption for Public Facilities Both Monroe County and Marathon have a "Rate of Growth Ordinance," also known as ROGO. A site proposed for development is ranked based on the environmental sensitivity of the property and receives negative points for greater environmental sensitivity. A site proposed for development can also receive positive points for such things as providing its own water system or elevation above the minimum flood insurance elevation. Monroe County and the City of Marathon award their annual allocation of development permits to the top-scoring sites. Proposed Rule 28-20.110 will make several modifications to the ROGO point allocation system in the Monroe County Comprehensive Plan. Existing Policy 101.3.4 of the Monroe County Comprehensive Plan provides that "public facilities shall be exempted from the requirements of the Permit Allocation System for new non-residential development." The existing policy also provides that certain development activity by enumerated federally tax-exempt, not-for-profit organizations "may be exempted from the Permit Allocation System by the County Commission after review by the Planning Commission upon a finding that such activity will predominantly serve the County's non- transient population." Proposed Rule 28-20.110(3) amends existing Policy 101.3.4 by requiring that the County Commission make an additional finding as a condition of exempting certain development activity by certain federally tax-exempt not-for- profit organizations from the Permit Allocation System. Pursuant to the proposed rule, the County Commission must also find that the "development activity is not planned within an area proposed for acquisition by governmental agencies for the purpose of resource protection." Petitioners contend that the provision of Proposed Rule 28-20.110(3), discussed above, is arbitrary and capricious and contravenes the law implemented in that the development activities of the federally tax-exempt, not-for-profit organizations covered by the proposed rule allows development activity on some environmentally-sensitive areas and is inconsistent with the Carrying Capacity Study. Existing Policy 101.3.4 allows development activity by not-for-profit organizations without a permit allocation because such development does not include overnight accommodations which might impact hurricane evacuation. Since a permit allocation was not necessary, such development was not affected by the negative points awarded for development in an area proposed for acquisition for resource protection. However, some not-for- profit organizations proposed development in environmentally- sensitive areas. The proposed change will prevent ROGO-exempt development on such lands and improve the protection of environmentally-sensitive habitat. Lot Aggregation Existing Policy 101.5.4, of the Monroe County Comprehensive Plan addresses the issue of lot aggregation and provides that "points shall be assigned to Allocation Applications for proposed dwelling units, which include a voluntary reduction of density permitted as of right within subdivisions (residential units per legally platted, buildable lots) by aggregating vacant, legally platted, buildable lots." This policy sought to reduce density within subdivisions by awarding or assigning positive points to applicants who aggregated two or more contiguous, vacant, legally buildable lots. The existing policy motivated and allowed applicants to purchase any contiguous property in order to be awarded additional points and, thus, increased their chances of receiving an allocation, even if the lots were in areas targeted for public acquisition for resource protection. Proposed Rule 28-20.110(4) amends Policy 101.5.4, Subsection 3, by prohibiting the awarding of points to Allocation Applications "for lot aggregation within those areas proposed for acquisition by public agencies for the purpose of resource protection." Petitioners assert that the proposed rule is arbitrary and capricious and contravenes the law implemented because it fails to adequately protect terrestrial habitat to the extent shown necessary in the Carrying Capacity Study. The basis of Petitioners' assertion is that under Proposed Rule 28-20.110(4), an applicant can get positive points for aggregating habitat, if the area is not proposed for acquisition by public agencies for the purpose of resource protection. Proposed Rule 28-20.110(4) will direct applicants seeking to be awarded additional points for "lot aggregation away from areas proposed for acquisition by public agencies for resource protection and, thereby, improve protection of terrestrial habitat. Clearing of Native Vegetation Existing Policy 205.2.7 of the Monroe County Comprehensive Plan provides that the "clearing of native vegetation shall be limited to the immediate development area." Under the existing policy, an applicant with aggregated lots would demand to clear a portion of both lots, so that a large portion of all of the lots would be cleared. Proposed Rule 28-20.110 amends existing Policy 205.27.7 by adding the following provision relating to the clearing of vegetation areas where Allocation Applications have received points for lot aggregation: For applications that receive points for lot aggregation under the Permit Allocation System for residential development, clearing of vegetation shall be limited to the open space ratios in Policy 205.2.6 or 5,000 square feet, whichever is less. The clearing of vegetation for ROGO applications that receive points for lot aggregation is also addressed in Proposed Rules 28-20.120(4), which adds a new provision, Regulation 9.5-347(e), to the Monroe County Land Development Regulations. That new provision is as follows: Section 9.5-347 (e) Lot Aggregation and Clearing: For ROGO applications that receive points for lot aggregation under Section 9.5-122.3 (a)(3), clearing of vegetation shall be limited to the open space ratios in paragraph (b) above or five-thousand (5,000) square feet, whichever is less. Petitioners contend that Proposed Rules 28-20.110(b) and 28-20.120(4) are arbitrary and capricious and contravene the law implemented, because they do not prohibit clearing of aggregated lots and are inconsistent with the Principles Guiding Development and with the Carrying Capacity Study. Notwithstanding Petitioners' assertions, even though the proposed rules do not prohibit all clearing of native vegetation, they will limit the amount of clearing for applicants who receive a ROGO allocation based upon lot aggregation. Under Proposed Rule 28-20.120(4), the clearing will be limited to an amount necessary to construct a reasonably-sized house. Technical Coordination Letter Proposed Rule 28-20.110(5), which will add a new policy, Policy 101.5.11, to the Monroe County Comprehensive Plan, provides the following: If not listed in the document "Parcels Not Located in Threatened and Endangered Species Habitat and Not Subject to FWS Consultation", or involving minor development activity exempted by the U.S. Fish and Wildlife Service (USFWS)", any application for a ROGO or NROGO allocation shall contain a technical coordination letter from the USFWS. The County shall consider the recommendations of the USFWS's technical coordination letter in the issuance of the subject permit, except that if a low-effect habitat conservation plan is required by USFWS, the mitigation requirements of that plan shall be incorporated in the conditions of the permit. As a result of federal litigation, the U.S. Fish and Wildlife Service ("USFWS") created a list of "Parcels Not Located in Threatened and Endangered Species Habitat and Not Subject to FWS Consultation." Monroe County and the DCA have developed the practice of requiring a technical coordination letter from the USFWS for development on parcels that are not on that list or are not otherwise exempt from USFWS review. Proposed Rule 28-20.110(5) incorporates into the Monroe County Comprehensive Plan a current practice that resulted from federal litigation. Monroe County Land Development Regulation 9.5-120 Proposed Rule 28-20.120(1) adds the phrase "species of special concern" to the following terms defined in Section 9.5-120(b) of the Monroe County Land Development Regulation as shown by the underlining: (1) "Known habitat of threatened/endangered animal species or species of special concern"; (2) "Potential habitat of threatened/endangered animal species" or species of special concern; and (3) Wide-ranging threatened/endangered animal species or species of special concern. This proposed change will conform the land development regulations to the Monroe County Comprehensive Plan by expanding the list of species that result in negative points under the Permit Allocation System to include "species of special concern." Existing Regulation 9.5-120(b) includes in the definitions of "known habitat of threatened/endangered animal species" and "potential habitat of threatened/endangered species" the sentence, "The county's threatened and endangered species maps shall constitute prima facie evidence of the species unless determined otherwise by the director of environmental resources." The definition of "wide-ranging threatened/endangered animal species" includes the sentence, "The county's threatened and endangered species maps shall constitute prima facie evidence of wide-ranging threatened or endangered species unless determined otherwise by the director of environmental resources."8 Proposed Rule 28-20.120(1) amends Section 9.5-120(b) by deleting the phrase, "unless determined otherwise by the director of environmental resources" from the sentences quoted above. Proposed Rule 28-20.120(1)(a) adds the following provision to the section of Regulation 9.5-120, which defines the term "known habitat of threatened/endangered species or species of special concern": (1) . . . The county's threatened and endangered species maps shall constitute prima facie evidence of the species. Within areas designated for public acquisition for the purposes of resource protection, any threatened, endangered or species of special concern species observed on site while conducting a habitat evaluation shall be noted on the adopted Threatened and Endangered Species Maps. Such observations noted while conducting a habitat evaluation by County Staff Biologists, consultants certified by the County, conducting habitat evaluations, or state or federal agency representatives conducting field inspections shall also constitute evidence of species. Petitioners contend that the portion of Proposed Rule 28-20.120(1)(a), quoted above, is arbitrary and capricious. Petitioners assert that the Proposed Rule fails to account for potential observations of "known habitat of threatened/endangered animal species" on parcels that are not within "areas designated for public acquisition for purposes of resource protection." Also, Petitioners assert that the Proposed Rule limits observations of species required to be noted on the adopted threatened and endangered species maps to consultants or scientists on the parcel specifically to conduct an HEI analysis and fails to require field verification of the parcel. Proposed Rule 28.20.120(1)(a) will expand the circumstances in which observations of listed species will cause modification of the adopted threatened and endangered species maps. Under the present land development regulations, Monroe County modified the maps only if a county staff biologist observed a listed species and did not take into account other professional observations. Monroe County Land Development Regulation 9.5-122.3 Regulation 9.5-122.3(a)(8) of the Monroe County Land Development Regulations establishes and assigns evaluation criteria and point assignment for applications for proposed dwelling units in Monroe County. The existing regulation requires that negative points be assigned to applications that propose a dwelling unit within a "known habitat of a documented threatened/endangered species" and a "potential habitat of threatened/endangered species." Proposed Rule 28-20.120(2) adds the following language to Section 9.5-122.3.(a)(8),9 as shown by the underlined provisions: Point Assignment: Criteria: -10 An application which proposes a dwelling unit within a known habitat of a threatened/endangered species or a species of special concern. For species of special concern, negative points shall only be applied to areas designated for public acquisition for the purpose of resource protection. -5 An application which proposes a dwelling unit within a potential habitat of a threatened/endangered species or a species of special concern. For species of special concern, negative points shall only be applied to areas designated for public acquisition purposes of resource protection. Regulation 9.5-1223.(a)(8), as amended, adds "species of special concern" to the species covered by the existing regulation. Also, the amended regulation requires that negative points be assigned to applications that propose dwelling units in a habitat of a species of special concern, if the area is designated for public acquisition for purposes of resource protection. Petitioners contend that Proposed Rule 28-20.120(2), which amends Regulation 9.5-122.3(a)(8), is arbitrary and capricious. As a basis for this contention, Petitioners assert that even though the Proposed Rule increases situations where an application is awarded negative points, it decreases protection of habitat by limiting the negative point award only to habitat of special concern that have been designated for public acquisition. Proposed Rule 28-20.120(2) increases situations in which an application will be awarded negative points by adding "species of special concern" to the species covered by Regulation 9.5-122.3(a)(8). By awarding negative points as provided in the proposed rule, there is increased protection of habitat for species of special concern. Monroe County Land Development Regulation 9.5-336 Proposed Rule 28-20.120(3) amends Section 9.5-336(b) of the Monroe County Land Development Regulations as follows: (b) Review and Amendment: The existing conditions map may be refined to reflect conditions legally in existence on February 28, 1986. Such refinements shall be made pursuant to the procedures for typographical and drafting errors in section 9.5-511(e). The existing conditions map as referenced throughout this chapter is intended only to serve as a general guide to habitat types for the purpose of preliminary determination of regulatory requirements. The county biologist shall make the final determination of habitat type based upon field verification, except that existing conditions that reflect disturbed with hammock shall be classified as a low quality hammock. Unlawful conditions shall not be recognized when determining regulatory requirements. Petitioners contend that Proposed Rule 28-20.120(3) is arbitrary and capricious and contravenes the law implemented because it does not protect all habitat. The existing conditions map was prepared in the 1980s. Many of the sites designated on the map as "disturbed with hammock" have re-vegetated since then. The proposed change will protect those sites by requiring clustering away from the hammock and by controlling the amount of allowed clearing. Hurricane Evacuation Monroe County and Marathon face a unique hurricane evacuation challenge. There is only one road out of the Florida Keys, and everyone must use that road to evacuate. For a Category 3 or greater hurricane, all areas of the Florida Keys must be evacuated because of the low elevations, the vulnerability to storm surge, and the logistics of post-disaster recovery. The Monroe County Comprehensive Plan and the Marathon Comprehensive Plan currently state that each ". . . shall reduce hurricane evacuation clearance times to 24 hours by the year 2010." The 24-hour standard was adopted by the Administration Commission at the conclusion of prior litigation over the Monroe County Comprehensive Plan. The term "hurricane evacuation clearance time" refers to the time that the emergency managers must call the evacuation before the arrival of tropical storm force winds. Hurricane evacuation clearance time includes both the time for citizens to mobilize (i.e., get their affairs in order, shelter their houses, take care of their belongings), and the time to evacuate the vehicles from the roadway. Tropical storm force winds typically arrive eight to 12 hours before the eye of the storm. In order to achieve a 24-hour hurricane evacuation clearance time, emergency managers must call the evacuation 32 to 36 hours before the arrival of the eye. The DCA contracted with Miller Consulting, Inc., to create a computer model to estimate the actual hurricane evacuation clearance time for the Florida Keys. The Miller model provides the best available data and analysis for estimating the clearance time. The latest run of the Miller model performed by the DCA using 2000 Census data, supplemented with development permit data up to August 2004, provides the best estimate of clearance time. This run of the Miller model estimates a hurricane evacuation time of 23 hours and 56 minutes to reach the beginning of the Homestead Extension of the Florida Turnpike on the mainland, and 24 hours and 48 minutes to reach the hurricane shelter at Florida International University ("FIU"). The beginning of the Florida Turnpike in Florida City is the appropriate endpoint for hurricane evacuation clearance time estimates. Florida City is a point of relative safety outside of the Category 3 vulnerability zone. Florida City is also the point of dispersal for the Florida Keys, where evacuees disperse to any number of destinations, such as South Dade, the FIU shelter, or a hotel in Orlando. The Miller model estimates that if those permit allocations are restored and the annual allocation is increased as described above, the hurricane evacuation clearance time next year will be 24 hours and four minutes. This exceeds the 24-hour standard adopted by the Administration Commission. Proposed Rule 28-20.110 adds the following requirement to Year Eight of the Work Program in Policy 101.2.13 of the Monroe County Comprehensive Plan and Policy 101.2.12 of the Marathon Comprehensive Plan: "Complete a comprehensive analysis of hurricane evacuation issues in the Florida Keys and develop strategies to reduce actual hurricane clearance times and thereby reduce potential loss of life from hurricanes." The Florida Keys' local governments have begun the comprehensive analysis of hurricane evacuation issues by convening a workgroup comprised of local government-elected officials and staffed by the DCA. The hurricane workgroup is considering alternative strategies to reduce clearance times, such as constructing an additional outbound lane, using transportation system management to create a temporary outbound lane, updating the assumptions for the Miller model, reducing transient occupancy, or calling the evacuation earlier. The working group must develop a strategy that balances or accommodates development and also addresses hurricane clearance times. The hurricane workgroup must do much more than simply squeeze a few more minutes out of the Miller model. There are currently 13,000 to 14,000 vacant platted lots in the Florida Keys, which must be allowed to develop or must be purchased by government. On average, 3,000 dwelling units generates about one hour of clearance time. As an example, if 8,000 or so lots were purchased for habitat protection, then two more hours of clearance time will be needed to accommodate the remaining 5,000 or 6,000 lots. The hurricane workgroup must develop a strategy to handle the amount of development permitting that can be expected and a program to acquire the balance of the vacant lots. Affordable and Workforce Housing There is an affordable housing crisis in the Florida Keys. The geography of the Florida Keys hinders the ability of working families in the Florida Keys to find affordable housing. Unlike other expensive areas, such as Boca Raton, working families cannot find affordable housing nearby; the nearest area where housing prices are affordable is the mainland in Dade County. From 1999 to 2003, there were 693 allocations for affordable housing units in the Florida Keys. This amount includes all the allocations for affordable housing units for that time period, even those allocations for which affordable housing units were not constructed. The number of affordable housing allocations issued from 1999 to 2003 and the number being issued under the existing Comprehensive Plans of Monroe County and the City of Marathon, are not sufficient to address the need for affordable housing. The Partnership Agreements recognize and address the affordable housing shortfall by increasing the number of annual affordable housing allocations, restoring residential allocations lost in previous years, and providing funding for the acquisition of land and the construction of workforce housing. As discussed above, Proposed Rule 28-20.110 implements the provisions of the Partnership Agreement by amending the Monroe County Comprehensive Plan as follows: increasing the number of annual affordable housing allocations from 32 to 71; (2) reallocating 140 unused allocations to affordable housing; and (3) requiring that the affordable housing remain affordable in perpetuity. Additionally, as specified in paragraph 60, the Work Program in Proposed Rule 28-20.110 requires Monroe County to complete tasks which will be an improvement of the affordable housing situation in Monroe County. As discussed above, Proposed Rule 28-18.210 implements the Partnership Agreement by amending the City of Marathon Comprehensive Plan as follows: (1) increases the overall number, though not the percentage, of allocations for affordable housing to six; (2) restoring 65 unused allocations for affordable housing; and (3) requiring that the affordable housing remain affordable in perpetuity. Also, as specified in paragraph 101, Proposed Rule 28-18.210 requires the City of Marathon to complete tasks that will result in improving the affordable housing issues in the City of Marathon. Proposed Rules 28-20.110 and 28-18.210 only partially address the affordable housing shortage in the Florida Keys. Nonetheless, the proposed amendments to the Comprehensive Plans of Monroe County and the City of Marathon will improve the current affordable housing shortage by increasing the number of affordable houses and providing the financial resources to make that more likely to occur. The Principles Guiding Development Subsection 380.0552(7), Florida Statutes (2004), provides in relevant part: PRINCIPLES FOR GUIDING DEVELOPMENT.- -State, regional, and local agencies and units of government in the Florida Keys Area shall coordinate their plans and conduct their programs and regulatory activities consistent with the principles for guiding development . . . . For the purposes of reviewing consistency of the adopted plan or any amendments to that plan with the principles for guiding development and any amendments to the principles, the principles shall be construed as a whole and no specific provision shall be construed or applied in isolation from the other provisions. . . . [T]he following shall be the principles with which any plan amendments must be consistent: To strengthen local government capabilities for managing land use and development so that local government is able to achieve these objectives without the continuation of the area of critical state concern designation. To protect shoreline and marine resources, including mangroves, coral reef formations, seagrass beds, wetlands, fish and wildlife, and their habitat. To protect upland resources, tropical biological communities, freshwater wetlands, native tropical vegetation (for example, hardwood hammocks and pinelands), dune ridges and beaches, wildlife, and their habitat. To ensure the maximum well-being of the Florida Keys and its citizens through sound economic development. To limit the adverse impacts of development on the quality of water throughout the Florida Keys. To enhance natural scenic resources, promote the aesthetic benefits of the natural environment, and ensure that development is compatible with the unique historic character of the Florida Keys. To protect the historical heritage of the Florida Keys. To protect the value, efficiency, cost-effectiveness, and amortized life of existing and proposed major public investments, including: The Florida Keys Aqueduct and water supply facilities; Sewage collection and disposal facilities; Solid waste collection and disposal facilities; Key West Naval Air Station and other military facilities; Transportation facilities; Federal parks, wildlife refuges, and marine sanctuaries; State parks, recreation facilities, aquatic preserves, and other publicly owned properties; City electric service and the Florida Keys Electric Co-op; and Other utilities, as appropriate. To limit the adverse impacts of public investments on the environmental resources of the Florida Keys. To make available adequate affordable housing for all sectors of the population of the Florida Keys. To provide adequate alternatives for the protection of public safety and welfare in the event of a natural or manmade disaster and for a post-disaster reconstruction plan. To protect the public health, safety, and welfare of the citizens of the Florida Keys and maintain the Florida Keys as a unique Florida resource. In determining whether the Proposed Rules are consistent with the principles, the principles should be considered as a whole. No specific provision should be construed or applied in isolation from other provisions. Ability to Manage Land Use and Development Principle A, set forth in Subsection 380.0552(7)(a), Florida Statutes, is "to strengthen local government capabilities for managing land use and development so that local government is able to achieve these objectives without the continuation of the area of critical state concern designation." Monroe County and the City of Marathon have evidenced a willingness and commitment to provide the funding required to meet the objectives of the Principles Guiding Development. Both local governments have included in the Proposed Rules tasks which reflect their understanding of the need to provide critical facilities, such as wastewater treatment facilities. While the need for such facilities has previously been acknowledged, the Proposed Rules provide a specific source of revenue to provide the needed facilities. Moreover, with regard to Monroe County, the proposed rules/regulations at issue in this proceeding strengthen the environmental protections measures in the Comprehensive Plans while allowing reasonable development. The proposed rules for Monroe County and the City of Marathon are consistent with Principle A. Environmental Issues Subsections 380.0552(7)(b), (c), and (e), Florida Statutes, are principles which require consideration of the impacts on the environment of the Florida Keys. Principle B is "to protect shoreline and marine resources, including mangroves, coral reef formations, seagrass beds, wetlands, fish and wildlife and their habitat." Principle C is "to protect upland resources, tropical biological communities, freshwater wetlands, native tropical vegetation (for example, hardwood hammocks and pinelands), dune ridges and beaches, wildlife and their habitat." Principle E is "to limit the adverse impacts of development on the water quality of water throughout the Florida Keys." Principle I is "to limit the adverse impacts of public investments on the environmental resources of the Florida Keys." The Proposed Rules of Monroe County and the City of Marathon include amendments to the Work Program which provide significant funding for sewage treatment systems that will enhance the protection of the shoreline and marine resources. The Proposed Rules of Monroe County and the City of Marathon are consistent with Principle B. The Proposed Rules of Monroe County improve protection of terrestrial habitat, limit clearing of native vegetation, and provide safeguards to ensure that parcels in threatened and endangered species habitat are protected. The proposed rules of Monroe County are consistent with Principle C. The portions of the Proposed Rules of the City of Marathon that are the subject of this proceeding do not specifically address Principle C. However, the Proposed Rules of the City of Marathon are not inconsistent with Principle C. Accordingly, the proposed rules of the City of Marathon are consistent with Principle C. The Proposed Rules of Monroe County and the City of Marathon limit the adverse impacts of development on the quality of water throughout the Florida Keys by the funding commitments that will hasten the construction of the sewage treatment facilities. The Proposed Rules of Monroe County and the City of Marathon are consistent with Principle E. The Proposed Rules do not encourage any public investment that would have an adverse impact on environmental resources. To the contrary, the Monroe County and the City of Marathon Proposed Rules provide for public investments in waste water improvements that are accelerated. Also, the Monroe County Proposed Rules prevent the construction of public facilities within a hammock area. The Proposed Rules of Monroe County and the City of Marathon are consistent with Principle I. Economic Development Principle D in Subsection 380.0552(7)(d), Florida Statutes, is "to ensure the maximum well-being of the Florida Keys and its citizens through sound economic development. The basis of the Florida Keys' economy is tourism, which is attracted by a clean and healthy environment. The increased protection of water quality that should be achieved by the hastened construction of sewage treatment facilities and the improved protection of habitat will strengthen the economy of the Florida Keys and provide the basis for a sound economic development. Also, the Proposed Rules balance environmental protection with property rights. The Proposed Rules of Monroe County and the City of Marathon are consistent with Principle D. Historical Character and Heritage Principle F in Subsection 380.0552(7)(f), Florida Statutes, is "to enhance natural and scenic resources, promote the aesthetic benefits of the natural environment and ensure that development is compatible with the unique historic character of the Florida Keys." Principle G in Subsection 380.0552(7)(g), Florida Statutes, is "to protect the historical heritage of the Florida Keys." The Proposed Rules of Monroe County and the City of Marathon will have little or no impact on the historic character and historical heritage of the Florida Keys. Thus, the Proposed Rules do no harm to either the historic character or historical heritage of Monroe County or the City of Marathon. Public Investments Principle H in Subsection 380.0552(7)(h), Florida Statutes, is "to protect the value, efficiency, cost- effectiveness, and amortized life of existing and proposed major life investments," including: The Florida Keys Aqueduct and water supply facilities; Sewage collection and disposal facilities; Solid waste collection and disposal facilities; Key West Naval Air Station and other military facilities; Transportation facilities; Federal parks, wildlife refuges, and marine sanctuaries; State parks, recreation facilities, aquatic preserves, and other publicly owned properties; City electric service and the Florida Keys Electric Co-op; and Other utilities, as appropriate. . . . The Proposed Rules of Monroe County and the City of Marathon do nothing to undermine the value, efficiency, cost- effectiveness or amortized life of existing major investments. Rather, the Proposed Rules will result in funding and timely construction of the major sewage and disposal facilities that are already contemplated by Monroe County and the City of Marathon's existing Comprehensive Plans.
