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

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.

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.
The Issue The issue posed herein is whether or not the Respondent, Arthur M. Jones, Jr.'s Wastewater Treatment Plant Operator's license should be suspended or revoked based on conduct set forth hereinafter in detail based on allegations as set forth in the Petitioner's Administrative Complaint filed January 31, 1979.
Findings Of Fact Based upon my observation of the witnesses and their demeanor while testifying, the arguments of counsel and the documentary evidence received, the following relevant facts are found. Respondent, Arthur M. Jones, Jr., is a duly certified Class C Wastewater Treatment Plant Operator, certified pursuant to Chapter 17-16, Florida Administrative Code. Respondent holds license No. 793 originally issued by the Florida Department of Health and Rehabilitative Services on May 13, 1971. The responsibility for certification of wastewater treatment plant operators was transferred to the Florida Department of Pollution Control by Executive Order 72-75. The Florida Department of Environmental Regulation is the successor agency to the Florida Department of Pollution Control by virtue of Chapter 75- 22, Laws of Florida, and is authorized by Section 403.101, Florida Statutes, to issue and revoke operators' certificates pursuant to its rules and Chapter 120, Florida Statutes. At all times material to this complaint, Respondent was employed by the Duval County School Board in Jacksonville, Florida. At all times material, Respondent was employed by the School Board as a School Sewer/Water Plant Mechanic, a position requiring certification by the Department as a Wastewater Treatment Plant Operator. In his capacity as a School Sewer/Water Plant Mechanic and Class C Operator, Respondent was responsible for the operation, supervision, maintenance and collection of influent and effluent samples from various Duval County schools. Persons responsible for the operation, supervision, maintenance and collection of influent and effluent samples must be licensed and certified by the Department as a Wastewater Treatment Plant Operator. Additionally, Respondent, in his capacity as a School Sewer/Water Plant Mechanic and Certified Class C Wastewater Treatment Plant Operator, was responsible for the proper collection of composite samples of raw sewage and the treated effluent from each such plant. According to instructions given the Respondent, a composite sample was to be taken by filling one-third of a sample bottle at two-hour intervals until the bottle was full. The composite sample of raw sewage was to be taken from the influent line and the composite sample of treated final sewage was to be taken from the effluent line. After the collection process, Respondent was responsible for properly and accurately labeling the composite samples and for depositing them in a refrigeration unit at School No. 98. The composite samples are then picked up at School No. 98 by authorized personnel for laboratory analysis to determine whether sewage is being adequately treated. The complaint, in summary fashion, alleged that the Respondent on or about February 15 and March 15, 1978, completely filled a raw sample bottle from the filter bed rather than from the influent line of the plant at School No. 94. That sample was submitted as a composite sample and placed in the refrigeration unit for pickup and analysis by laboratory personnel. Additionally, the complaint alleges that on February 15, 1978, at School No. 82, Respondent filled raw and final sample bottles for Schools Nos. 82, 64, 83 and 153, none of which were a proper composite sample. The samples, it is alleged, were all taken from School No. 82. The complaint alleges that similar acts occurred on March 15, 1978; on April 4, 1978 and April 11, 1978, all of which acts "constitute gross neglect and fraud in the performance of duties as an operator of a wastewater plant." Based thereon, the Petitioner seeks revocation of the Respondent's Class C Wastewater Treatment Plant Operator's license. L. L. Masters is Respondent's foreman and is in charge of the wastewater treatment plant facilities. Masters is Respondent's immediate supervisor. On March 15, 1978, Foreman Masters assigned Respondent the duties of taking composite samples of Schools 94, 64, 83, 82 and 159. Evidence reveals that Foreman Masters arrived at School 82 at 9:00 o'clock a.m. and departed at 2:00 p.m. Evidence also reveals that Foreman Masters had a clear view of the entire wastewater treatment plant and that it was impossible for the Respondent to enter and leave the treatment plant in a manner whereby composite samples could be collected without Foreman Masters seeing him. In this regard, Respondent's work orders reflect that he reported having arrived at School 82 at 10:40 a.m. and departed at 12:10 p.m. (Petitioner's Exhibits 5, 6, 7 and 8.) On April 4, 1978, Respondent was assigned to collect composite samples from Schools 72, 233, 76 and 208. (Petitioner's Exhibit 9.) Foreman Masters observed Respondent on April 4, 1978, with employee Carl Casey. Masters went to School 77 at 8:30 and Respondent was not there, although he had given a dispatcher a routing which would have taken him to School 76. When Foreman Masters noted that Respondent had not arrived at School 76 by 8:30 a.m., he took employee Carl Casey to School 233 and left Casey at School 233 while he returned to School 76. The Respondent was not there and Masters drove to School 208 where the Respondent arrived at approximately 9:30 a.m. It suffices to say that the Respondent then left for School 233 and arrived there at 10:30. From approximately 10:45 to 11:45, the Respondent was in the wastewater treatment area of School 233 and took three samples from the effluent line and three samples from the influent line at School 233 from the period 10:30 a.m. through 11:45 a.m. (Petitioner's Exhibits 9, 10 and 11.) Employee Pat Wilson testified that he accompanied Respondent on February 15, 1978, and that all samples were taken from the filter beds of Schools 98 and 82. Detective Jack C. Adams of the Jacksonville Police Department was assigned to the surveillance of Respondent on April 11, 1978. Detective Adams credibly testified that the Respondent did not take composite samples from the assigned schools as reflected by the work orders submitted by Respondent Respondent appeared and testified that one of the events for which he had been charged occurred as alleged; however, he testified that inasmuch as he questioned the procedures, he was of the opinion that since no harm was done, and since no school experienced problems, he is not guilty of gross neglect and fraud in the performance of his duties as an operator of a wastewater treatment plant as alleged. The evidence herein reveals that the Respondent was instructed as to the proper procedures for testing, collecting and preserving composite raw and final samples from wastewater treatment plants by his employer. He testified that he had attended a seminar wherein the instructions for such procedures were outlined to him and that he was given a manual on the methods for collecting raw and final samples. Barry McAlister, a certification officer for the Department, testified that Class C operators are instructed as to the proper procedures for collecting samples. Additionally, he testified that the submitting agencies rely heavily on the operators to properly collect samples which are submitted for analysis. Chapters 17-19.04, Florida Administrative Code, additionally set forth the sampling and testing methods for collection and preservation of composite samples. Although there was some conflicting testimony respecting the adherence to the procedures uniformly by the various wastewater treatment plant operators employed by the School Board, the undersigned is of the opinion that the Respondent was not at liberty to select and choose the manner within which he would collect composite samples for analysis by his employer in view of outstanding instructions which were in effect during his employment.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is hereby, RECOMMENDED: That the Respondent, Arthur M. Jones, Jr.'s license as a Class C Wastewater Treatment Plant Operator be suspended for a period of two (2) years. RECOMMENDED this 28th day of September, 1979, in Tallahassee, Florida. JAMES E.

Farley, Jr., Esquire Mahon, Mahon & Farley 350 East Adams Street Jacksonville, Florida 32202
The Issue The issue is whether Petitioner is entitled to an operating permit for an existing domestic wastewater treatment facility operating in Naples.
Findings Of Fact On May 10, 1991, Respondent issued Petitioner a five- year permit to operate a 0.3 million gallon per day (GPD) domestic wastewater treatment plant known as the Rookery Bay facility in Naples. This permit, which is number DO11-187204, allowed Petitioner to operate an extended aeration plant, using chlorine for basic disinfection and disposing of the reclaimed water in two percolation ponds. The 1991 permit required Petitioner to allow Respondent access to the facility for inspections at reasonable times, notify Respondent of any violations of any permit conditions, maintain total chlorine residual of at least 0.5 milligrams per liter (mg/L) of effluent sample after at least 15 minutes’ contact time at maximum daily flow, maintain annual average effluent quality values for carbonaceous biochemical oxygen demand (CBOD) and total suspended solids (TSS) of not more than 20 mg/L of effluent sample with maximum effluent quality concentrations of 60 mg/L in any single effluent sample, maintain a monthly average effluent quality value for fecal coliform of not more than 200 per 100 ml of effluent sample with a maximum effluent quality value of 800 per 100 ml in any single effluent sample, notify Respondent of any discharge from the percolation pond overflows, and monitor influent loading to the facility and apply for a permit modification if the monthly average influent flows approach or exceed the design capacity of 0.3 MGD or if the facility violates treatment standards. Respondent also issued Petitioner a five-year permit to operate a 0.15 GPD domestic wastewater treatment plant at the Rookery Bay facility. This permit, which is number DO11-167093, allowed Petitioner to operate a contact stabilization process plant. On December 29, 1995, Petitioner submitted a renewal application for permit number DO11-167093. Although the permit number references the smaller tank, the renewal application requests a permitted capacity of 0.3 MGD. By Notice of Permit Denial dated February 9, 1996, Respondent denied the permit application on the ground that Petitioner could not provide reasonable assurance that it would operate the facility in compliance with state standards based on a “continued and long standing pattern of noncompliance and violation of . . . rules and standards.” Petitioner’s operation of the Rookery Bay treatment plant has been poor. Respondent has brought an enforcement action against Petitioner, which signed a consent final judgment in January 1994. The consent final judgment required Respondent to pay $4500 in civil penalties. As it applied to the Rookery Bay facility, the consent final order required Petitioner to evaluate the facility to discover the causes of past violations and modify the facility to eliminate these violations. But Petitioner has not complied with material provisions of the consent final judgment. Petitioner’s operator has been held in contempt of court several times for violations at Rookery Bay and a nearby smaller treatment facility known as Port au Prince. Petitioner has several times refused Respondent’s representatives reasonable access to the Rookery Bay facility. At least twice, Petitioner has failed to advise Respondent of equipment failures that resulted in violations of treatment standards. On January 11, 1995, Petitioner cut off the power for several hours to a lift station pump serving a nearby a condominium complex. Predictably, the sewage backed up and overflowed into the street. Petitioner failed to restore the power timely or remove the overflowed sewage. On several occasions, raw or inadequately treated sewage has leaked from the tanks at the Rookery Bay facility. Petitioner has failed to eliminate this problem over the course of its five-year operating permit. On numerous occasions, Respondent’s representatives have detected violations of effluent quality. These violations have arisen inadequate detention time in the chlorine contact chamber. Consequently, the TSS and CBOD levels have repeatedly exceeded permitted standards. The parties dispute the adequacy of the capacity of the Rookery Bay facility. There is considerable evidence, including one statement in the application, that suggests that the facility’s capacity is seriously inadequate. Either the capacity of the Rookery Bay is, and has been, inadequate--in which case at least some of the violations are attributable to overcapacity operation--or, if the facility has had adequate capacity, the operational competence of Petitioner is below the minimum level necessary to provide reasonable assurance of proper operations at this facility in the future. Most likely, the Rookery Bay facility lacks adequate capacity, at least part of the year, and Petitioner lacks the minimum requisite competence to operate the facility in a responsible manner. The strongest evidence in the record suggests that the Rookery Bay facility serves, during peak season, 1500 mobile home connections and 400 apartment connections. These connections generate about 377,500 GPD of raw sewage. A slightly lower value is probable after consideration of the likely presence of recreational vehicles among the mobile home count. But this reduction, even without adjustment for dry-season infiltration and inflow, would not yield sufficient savings in raw sewage as to provide reasonable assurance that the Rookery Bay facility has adequate capacity to serve the present demand or adequate capacity to serve the demand projected over the five-year term of the permit that Petitioner seeks. Even if one were to credit Petitioner’s volume-to- capacity calculations, the results fail to constitute reasonable assurance of violation-free operation of the Rookery Bay facility. Petitioner's calculations leave little if any margin for error at present demand levels, and, given Petitioner’s singularly poor operating history at this facility, these calculations provide poor assurance of compliant operation of this troubled facility.
Recommendation Based on the foregoing, it is RECOMMENDED that the Department of Environmental Protection enter a final order denying Petitioner’s renewal application for a domestic wastewater treatment operating permit for the Rookery Bay facility.

Findings Of Fact During 1990, Respondent/Applicant, City of Lynn Haven, filed several applications with the Respondent, Department of Environmental Regulation, seeking the issuance of several permits to build a wastewater collection system and a two million gallon per day advanced wastewater treatment (AWT) plant. The proposed facility is intended to replace the wastewater treatment facility currently being used by the City of Lynn Haven. After a review of the applications the Department proposed several Intents to Issue covering the different aspects of the proposed projects. The Intents to Issue included: A) a variance and dredge and fill permit, pursuant to Sections 403.201, 403.918, 403.919, Florida Statutes, and Rule 17-312, Florida Administrative Code, authorizing a subaqueous crossing of North Bay (Class II waters) and installation of a force main (permit #031716641), B) a collection system permit, pursuant to Chapter 403, Florida Statutes, and Rules 17-4, 17-600 and 17-604, Florida Administrative Code, for the installation of approximately 11 miles of pipe from North Bay to the proposed treatment plant, C) a dredge and fill permit #031785181, pursuant to Sections 403.918, 403.919, Florida Statutes, and Rules 17-4, 17-312, Florida Administrative Code, authorizing 10 incidental wetland crossings associated with the collection system, and, D) a construction permit #DC03-178814, pursuant to Chapter 403, Florida Statutes, and Rules 17-4, 17-302, 17-600 and 17-611, Florida Administrative Code, authorizing the construction of a 2.0 mgd wastewater treatment plant. Sand Hill Community Improvement Association challenged the Department's Intents to Issue. The Sand Hill Community Improvement Association (Sand Hill) is an association composed of 74 formal members plus numerous supporters. Both members and supporters are residents who live near the site of the proposed Lynn Haven sewage treatment plant. They are sufficiently close to the plant site that construction of the proposed project could impact their property. The members are very concerned about any threat of pollution to the aquifer from the proposed plant since all of the members are dependent on private wells for their drinking water. Additionally, members of the association use the proposed site, as well as the associated wetlands, Burnt Mill Creek and the nearby lakes, for a variety of recreational purposes, including hunting, fishing, hiking, bird-watching, boating and swimming. Given these facts, the Association has standing to challenge the Department's Intents to Issue involved in this case. The City of Lynn Haven is located on a peninsular section of the south shore of North Bay and, except for its connection to the land, is surrounded by environmentally sensitive Class II or Class I waters. Lynn Haven's existing wastewater treatment plant was poorly designed, has not worked properly, and is old and outdated. The plant is permitted to treat up to 950,000 gallons per day. However, the existing plant is currently exceeding its originally permitted treatment limits and is treating in excess of 1,200,000 gallons per day. The sewage only receives secondary treatment, Secondary treatment is the minimum state standard for wastewater treatment. The secondarily treated wastewater is pumped several miles to a spray irrigation site located in the eastern portion of the City. The sprayfield site has never worked properly due to a high groundwater table and a confining layer of soil, both of which prevent the effluent from percolating into the ground. Because the sewage effluent cannot percolate into the ground, the existing operation frequently results in direct runoff into a ditch which empties into North Bay, a Class II waterbody. Such discharge of wastewater effluent into Class II waters is prohibited by Department regulations. 1/ At this time, the existing wastewater treatment facility is in violation of both DER and EPA standards and is under enforcement action by both agencies. The existing facility is currently operating without a permit and the Department has advised Lynn Haven that the existing facility as it now operates can not be permitted. In fact, all the parties agree that the City is in serious need of a wastewater treatment facility which works and does not pollute the environment. However, the parties disagree over the method by which proper wastewater treatment could be accomplished by Lynn Haven. Since 1972, the City, through various consultants and with the aid of DER, has reviewed approximately 40 alternatives for wastewater disposal. After this review, the City of Lynn Haven selected the alternative which is the subject of this administrative hearing. The alternative selected by the City of Lynn Haven consists of the construction of a proposed advanced wastewater treatment (AWT) plant and distribution system. The new plant will be on a 640 acre parcel of property located approximately 12 miles north of Lynn Haven. The location of the new plant will necessitate the rerouting of the wastewater from the old plant to the new plant by construction of a new transmission line approximately 12 miles north of the City across North Bay and parallel along State Road 77. 2/ The treatment process proposed for use in the new AWT plant is known as the AO2 process. The process is patented. The AO2 treatment process primarily consists of biological treatment with settling and filtration. The treatment process also includes a chemical backup treatment to further reduce phosphorus if necessary. The evidence demonstrated that this type of facility has been permitted by the Department in at least five other wastewater facilities throughout the state. The treatment facility will have a two million gallon per day, lined holding pond on site for the purposes of holding improperly treated wastewater for recirculation through the proposed facility. Any excess sludge generated by this treatment process would be routed to lined, vacuum-assisted, sludge drying beds. The sludge would then be transported offsite to a permitted landfill for disposal. The evidence demonstrated that this treatment process would not produce any objectionable odors. Once the wastewater is treated, it will be disinfected by chlorination to eliminate pathogens. The chlorination process is expected to meet state standards. After chlorination, a dechlorination process would occur to remove any chlorine residuals which would have a harmful affect on the environment. The treated wastewater would then be re-aerated and discharged through the distribution system indirectly into a wetland located on the 640 acre parcel of property. The quality of the treated wastewater is expected to meet the advanced wastewater treatment (AWT) standards. These standards are five milligrams per liter total suspended solids (T.S.S.), five milligrams per liter BOD, three milligrams per liter nitrogen (N), one milligram per liter phophorus (P). Ph will be in the range of six to eight units on an average annual basis and can be adjusted up or down if necessary to meet the ph levels of the ecology into which the wastewater ultimately flows. This effluent quality is approximately five times cleaner than secondarily treated effluent. Additionally, as a condition of the draft permit, the proposed facility would be operated by a state-licensed operator and would be routinely monitored to insure that the treated wastewater effluent meets advanced wastewater treatment standards. Given these facts, the evidence demonstrated that the applicant has supplied reasonable assurances that the plant will perform as represented and that the effluent will meet the state standards for advanced wastewater treatment. As indicated earlier, the site for the proposed AWT plant contains approximately 640 acres and is located approximately 12 miles north of Lynn Haven in an area known locally as the Sand Hills. The City specifically purchased this parcel of property for the construction of the proposed wastewater treatment plant. The plant itself would be located in the northeast corner of the property. The 640 acre site was previously used for silviculture. The entire area is currently planted in pines except for a low area that is dominated by a pristine, woody wetland system of titi. The titi wetland is approximately 212 acres in size and generally runs through the center of the property from the northeast to the southwest. The wetland is low in acidity, with an estimated ph between 4 and 5. The site consists of hilly, mineralized soils. The soils within the forested wetland are organic in nature. Based on the evidence at the hearing, there does not appear to be any significant confining layers of soil which would prevent the treated wastewater from percolating in the soils and draining towards the wetland and ultimately into Burnt Mill Creek, a Class III waterbody. Once the effluent leaves the plant, it would go through a distribution system. The proposed distribution system will consist of six, 500 foot long, 12 inch diameter perforated pipes. Each 500 foot section of pipe has 100 one and one-half inch orifices which will discharge the treated effluent onto an eight foot wide concrete pad. This concrete pad will dissipate the effluent's energy, prevent erosion at the orifice site and insure that the effluent sheetflows onto and eventually into the sandy soils of the plant site and ultimately into the receiving wetland. The distribution pipes are located around the east, north and western portions of the receiving wetland and are variously set back from the receiving wetland approximately 80 to 200 feet. The distribution system is designed with valves to allow for routing of flow to different branches of the system if it is determined through long term monitoring that there is a need to allow for any of the receiving wetland to dry out. None of the distribution branches are located in any jurisdictional wetlands of the State of Florida. The receiving wetland will receive a hydraulic loading rate of approximately 1.8 inches per week once the new advanced wastewater treatment plant is operating at capacity. Both the surface waters and groundwaters on the 640 acre parcel flow from northeast to southwest across the property. The evidence clearly demonstrated that any treated wastewater discharged on the site would move down hill by surface or groundwater flows towards the wetlands in the central portion of the property and eventually discharge into Burnt Mill Creek located at the southwest corner of the parcel. The evidence demonstrated that it would be highly unlikely for the surface or groundwater to move in any other direction and would be unlikely for the surface or groundwater to move towards any residents located to the north or east of this parcel. Evidence of the topography and its relatively sharp gradient clearly demonstrated that the treated wastewater discharged in the northeast corner of this site would not result in any significant still water ponding and would exit the site at the southwest corner of the property in approximately 14 hours. The evidence did demonstrate that, depending on the wetness of the weather, there may likely be certain times of the year when a flowing type of ponding would occur. However, this wet weather ponding was not shown to be of a duration which would impact to a significant degree on the flora and fauna of the area or increase the number of disease bearing mosquitoes in the area. As indicated earlier the treated effluent from the proposed AWT plant will flow into Burnt Mill Creek. Burnt Mill Creek will ultimately carry the treated wastewater approximately 11 miles down stream to North Bay. The City can directly discharge up to two million gallons per day of AWT water into Burnt Mill Creek without violating state water quality standards. Therefore, the volume of wastewater discharged into Burnt Mill Creek should not have significant impacts on surface and ground water quality. Moreover, Chapter 17-611, Florida Administrative Code, authorizes the discharge of up to 2 inches per week to receiving wetlands provided wastewater is treated to AWT standards. The evidence demonstrated that this rule was developed as an experimental effort to determine if wetlands could be appropriate areas for wastewater effluent to be either discharged or treated. These state limits were intended to be very conservative limits and were designed to insure that the impacts to receiving wetlands would be minimal. The evidence and testimony demonstrated that the receiving wetland system involved in this case should not be adversely impacted beyond those limits set forth in Section 17-611.500, Florida Administrative Code, for flora, fauna, macroinvertebrates, fish or vegetation and will meet all standards set forth in Chapter 17-611, Florida Administrative Code. However, it should be noted that the wetland/wastewater program is highly experimental and very little is known about the actual impacts of wetland/wastewater systems since facilities similar to the one proposed by Lynn Haven have not yet been placed in service. The evidence did show that there would be some long term impacts to flora and fauna in the wetland area primarily due to ponding, changed ph and the introduction of nutrients and pollution in the form of the effluent. However, the regulation does allow for some change within a receiving wetland and the evidence did not demonstrate that these changes would be significant or detrimental. Petitioners' own witness concluded that other deep wetland treatment systems are doing a very good job in meeting state water quality standards. Although Petitioners' expert noted potentially adverse impacts to flora and fauna from other wastewater treatment systems, these other systems were slow moving, impoundment-type systems that are not similar to the wastewater/wetlands system proposed by the City of Lynn Haven. The Lynn Haven system is designed for percolation and sheetflow, not ponding. Though there should be some expected changes, no evidence was provided that the receiving wetlands for the Lynn Haven facility would be affected to the extent there would be violations of any standard as set forth in Chapter 17-611, Florida Administrative Code. In essence, the legislature has determined that such experimentation with wetland areas is appropriate, albeit, even with the conservative limits of DER's rule, may prove to be a mistake. This facility is designed to fit within that rule and in fact is probably the best technology available for use in a wetland/wastewater situation. Finally, in order to avoid any potential impacts on the area which may over time become significant an approved monitoring program for surface water quality and affects on flora and fauna, as well as a groundwater monitoring program are required as conditions of the permit. The groundwater monitoring program has been designed to monitor any potential long term impacts to groundwater. With these protections there should not be any significant adverse impacts to surface or groundwater quality and the applicant is entitled to a construction permit for the AWT plant and distribution system. Lynn Haven's sewage would reach the proposed AWT plant through a transmission line. The transmission line would run from Lynn Haven's existing wastewater treatment plant across North Bay and through the unincorporated area of South Port. The Southport area is not sewered and utilizes individual septic tanks for its sewage. The transmission line would be constructed entirely in state road right-of-way. The line would terminate at the 640 acre site described above. A new, variable speed pumping station would be constructed adjacent to the old wastewater treatment plant. From this pump station, a 24 inch line would be constructed on City right-of-way up to the south shore of North Bay. At this point, the transmission line would be reduced in size to 20 inches and would be embedded approximately three feet below the Bay bottom. An additional variable speed pumping station would be located approximately half way along the 12 mile route of the transmission line to insure adequate pressure to pump wastewater to the new wastewater treatment plant. The pumps are to be employed to insure that the wastewater is continuously pumped uphill to the new site so that waste does not set, become septic, and create odor problems. The pumps are equipped to provide for chemical control of odor if necessary. Also, as a condition of the permit, the pumping stations are required to have backup power supplies should power be lost to the stations. The pumping stations and backup power supplies are to be tested monthly and the pumps are required to be continuously monitored by radio telemetry to insure they are operating properly. Additionally, the City of Lynn Haven will be required, as a condition of the permit, to visually inspect the entire length of the wastewater transmission line three times per day. The portion of the transmission line which would cross North Bay is approximately 3000 feet in length and would be constructed of high density polyethylene pipe (HDPE) with a wall thickness of one and one-half inches. HDPE pipe is used to transport materials such as hazardous wastes where leakage is not permissible. This type of pipe is virtually inert in that it is highly resistant to corrosion and other chemical reactions. It is also impact resistant and has a very high tensile strength. The pipe comes in 40 foot segments and is heat welded (fused) together. This type of joint significantly reduces the chance of any leakage. In fact, leakage around pipe joints is more likely to occur with other types of pipe and pipe connections. HDPE pipe is currently carrying wastewater across Watson Bayou in Bay County, Florida. 3/ There have been no reported problems with leaks or breaks occurring in the pipe crossing Watson Bayou. Given these facts, the probability of the proposed HDPE pipe leaking or breaking is extremely low, albeit not impossible, and such pipe appears to be the best material available for constructing a wastewater treatment transmission line across protected waters of the State. As a condition of the construction permit, the portion of the transmission line crossing North Bay will be required to have isolation valves at each end so that the pipe may be completely isolated in the event that it needs repair. The underwater portion of the line would be visually inspected by a diver twice per year and the line would be pressure tested before being placed into service. Additionally, pressure tests would be performed once a year. The construction permit also requires Lynn Haven to periodically inject dye into the proposed transmission line to check for any small leaks that may not otherwise be detected. Finally, the HDPE pipe would also be equipped so that television cameras could be inserted into the pipe to routinely inspect the interior of the pipe. In the event the HDPE portion of the transmission line would need to be repaired, the line could be immediately, temporarily repaired by a dresser coupling. A permanent repair could then be made in less than 24 hours once the material and equipment were staged at the site. The City intends to locally stockpile all necessary parts and equipment to effect any required repair to prevent any delay beyond four days. Permanent repairs would be accomplished by floating the line to the surface. The area needing repair would be cut out and a new section would be put in place by heat fusion. The line would then be pressure tested to insure the absence of leaks and placed back into service. During this process, the line would be taken out of service by the isolation valves and flow would be diverted to the eight million gallon holding ponds at the City of Lynn Haven's existing facility. These holding ponds can hold four days worth of wastewater from the City of Lynn Haven. Lynn Haven is required, as a condition of the construction permit, to have this reserve capacity as well as have a contractor on standby to make any repairs in the event such repairs are necessary. All of the technical specifications for the transmission system and the operating conditions imposed on it are designed to insure that the system does not fail or develop any leaks which could impact receiving waters, including North Bay. Given the permit conditions, the required inspections for leaks, the sound engineering design and quick repair methods proposed, the evidence demonstrated that the probability of any leak occurring in the portion of the transmission line crossing North Bay is extremely low and that if such a leak does occur any potential harm to the environment will likely be limited and quickly eliminated. The evidence demonstrated that the design of the transmission line and permit conditions provide reasonable assurances that the transmission line will meet or exceed the Department standards set forth in Chapter 17-604, Florida Administrative Code. Therefore, the applicant has provided reasonable assurances that the transmission line/collection system will not violate Department standards or rules and the applicant is entitled to a permit (permit #CS03-178910) for the proposed collection system. In addition to requiring a construction permit/collection system permit for the wastewater transmission line, the line will also require dredge and fill permits and a variance for crossing waters of the state. There are ten incidental crossings of state waters and one major crossing o f North Bay. Of the ten incidental crossings, two are over small creeks (Scurlock and Little Burnt Mill) These two incidental creek crossings will be accomplished by placing the transmission line (ductile iron pipe) on top of pilings placed in the water. Best management practices such as turbidity curtains and other erosion control practices are proposed and required by the permit to minimize construction impacts on water quality. The only impacts to wetland resources would be from the placement of the pilings. The evidence demonstrated that any impact would be minimal and not significant. The evidence did not demonstrate that the aerial crossings would have any long term water quality or environmental impacts. The remaining eight incidental crossings of waters of the state consist of small, seasonally wet ditches which would be traversed by trenching and burying the transmission line. Again, turbidity controls such as curtains and hay bales would be employed to protect water quality. The evidence did not demonstrate that any significant long term or short term impacts to resources of the state would occur. The evidence did demonstrate that the applicant has provided reasonable assurances that water quality standards would not be violated in regards to these 10 incidental water crossings. Likewise, the evidence demonstrated that the construction of these 10 incidental water crossings would not be contrary to the public interest. Therefore, the applicant is entitled to issuance of a dredge and fill permit (permit #031785181) for these 10 water crossing. However, a much harder question arises in relation to the dredge and fill permit and the variance required for the 3,000 foot segment of the wastewater transmission line which crosses North Bay. Pursuant to Rule 17- 312.080(7), Florida Administrative Code, permits for dredging and filling activity directly in Class II waters which are approved for shellfish harvesting by the Department of Natural Resources (DNR) shall not be issued. The reason for the rule is that any pollution caused by dredging and filling and, as in this case, the permanent placement of a sewage pipe in food producing waters could potentially have catastrophic effects on more than just the environment but on local employment in the shellfish industry and the quality of food available to the State. Put simply, the Department has determined by enacting its Rule that the public interest in food producing waters far outweighs any other consideration or criteria under Sections 403.918 and 403.919, Florida Statutes, in determining whether dredging and filling should take place in Class II, shellfish waters. In other words, it is not in the best interest of the public to allow dredging and filling so that a pipe carrying raw sewage can be placed in shellfishing waters. However, irrespective of this determination, the Department believes that, pursuant to Section 403.201(1)(c), Florida Statutes, it may grant a variance from its rules to relieve a hardship. As indicated earlier, North Bay is a Class II waterbody, conditionally approved for shellfishing. North Bay, therefore, falls within the Rule's prohibition against dredging and filling in Class II waters and the City is required to demonstrate the presence of a hardship in order to vary the Rule prohibition and obtain a dredge and fill permit for the North Bay crossing. On issues involving variances, the Department employs a two step analysis. The first part of the analysis is whether a hardship is present and the second is whether, if the variance were granted, would it result in permanent closure of Class II shellfish waters. The Department correctly recognizes that the question of whether a hardship exists is a question of fact and is determined on a case-by-case basis. Surprisingly, in a kind of "what we don't know can't hurt" posture the Department reviews a request for a variance standing alone based on the application as it is presented and does not require analyses of other possible alternatives to the granting of a variance. However, the existence of any alternatives, costs of any alternatives, timeliness of any alternatives, problems with any alternatives, whether an alternative represents a short term or long term solution to a given problem and the implementability of any of the alternatives are all factors utilized by the Department in determining whether or not to grant a variance. The Department's policy of non- review makes no sense, either factually or statutorily, when the Department is faced with varying a prohibition it created in its own rules. Similarly, the Department's policy of not requiring other alternatives to be examined before granting a variance goes against the fact that an applicant has the burden to establish entitlement to a permit and, in the case of a hardship variance, that a hardship exists because reasonable alternatives to granting a variance are not available. 4/ Likewise, the second part of the Department's hardship analysis relating to the permanent closure of shellfishing waters makes no sense given the fact that a non-permanent closure of shellfishing waters may have the same or just as serious effect on employment in the shellfishing industry, the loss of income due to an inability to earn a living in that industry and health risks posed by contaminated seafood. Temporary loss of income or a livelihood can, for all practical purposes, have consequences to the persons directly affected by a temporary closure of shellfishing waters similar in nature those caused by the permanent closure of shellfishing waters. The same can be said for health risks posed by a contaminated food supply. Rule 17-312.080(7), Florida Administrative Code, does not contain any exceptions for the temporary closure of shellfish waters. Nor is the rule limited to instances of permanent closure. Permanent closure is simpy not required in order to support a hardship under Section 403.201, Florida Statutes. Moreover, neither step in the Department's two-step analysis is included in any Rule promulgated by the Department. 5/ Without such a Rule, it is incumbent upon the Department or the applicant to demonstrate the underpinnings for this non-rule policy. No such evidence was presented at the hearing. In fact, the evidence presented at the hearing affirmatively demonstrated that the Department's non-rule policy violated both its own rules and the statute under which it is trying to proceed. As indicated, the issue of hardship is a question of fact and involves a weighing of all the facts and cicumstances involved in this project. In this case, there are shellfishing areas located close to the proposed location of the transmission line. North Bay is sometimes closed to shellfish harvesting by the Department of Natural Resources. These closures generally occur during wet weather conditions and are due to stormwater runoff and the failure of septic tanks in Southport. 6/ Additionally the current Lynn Haven system also contributes to the closure of North Bay. No competent, substantial evidence was provided that issuance of the permit and variance would result in the permanent closure of shellfish waters. The location of the proposed transmission line would be several hundred feet west of the Bailey Bridge embedded in the Bay floor. 7/ The proposed alignment of the transmission line through North Bay is in an area which is relatively biologically unproductive. The proposed placement of the transmission line avoids the few grassbeds that exist in the nearshore shallow areas except for approximately 200 square feet of grass. During construction of the line, these grasses would be removed immediately before the line is placed in a trench and then would be promptly replanted in the same area. The evidence demonstrated that the affected areas of grass should be able to reestablish itself. The evidence further demonstrated that there would not be any long term adverse impacts to these aquatic resources and there should not be any significant long term impacts on the balance of any aquatic life which may exist on the bay bottom. Water quality during construction will be protected by use of turbidity controls to control sediments. Therefore, any short term impacts on aquatic resources are likely to be insignificant. Concerns about long term adverse impacts to Class II waters are greatly reduced by the type of pipe and conditions in the permit which require that the transmission line be routinely inspected and tested to insure that there is no leakage and that in the unlikely event the line should need to be repaired, the line could be easily isolated and quickly repaired. The evidence showed that, to completely avoid Class II waters, the line could be moved several miles to the west or east of the line's proposed location or be placed over or under the Bay. If the line was moved west to the extent that it was in Class III waters, it would be over 40 miles long and would more than double the cost of the project. If the line was moved several miles to the east, it would go through the Deer Point Lake Watershed. The watershed is a Class I water supply for Bay County. Clearly, moving the line either west or east is not practical nor realistically feasible. Tunneling under North Bay would be very risky and is not technically feasible. The length of the tunnel would require steel pipe to be used. If tunneling could be done at all steel pipe would not provide the level of protection afforded by the HDPE pipe proposed by Lynn Haven. Placing the transmission line on pilings for an aerial route over North Bay is uneconomical and would create a potential hazard to navigation. Moreover, an aerial crossing would not solve any pollution problems should the transmission line leak or break and would also still involve a variance request since it would be necessary to dredge and fill in Class II waters for the placement of pilings or supports. Put simply, the evidence, showed that there was no realistic way to avoid Class II waters in North Bay given the location of the proposed wastewater treatment facility. A location which the City knew would require a hardship variance from the rule prohibition of dredging and filling in Class II, shellfishing waters. A hardship which the City created by site selection and which it hoped to overcome by strenuous permit conditions and futuristic speculative benefits to unsewered areas of the County. The existing treatment facility is operating in violation of both EPA and DER requirements, has been issued a notice of violation, is nonpermitted and is destined to be operating under a consent order. The system is hydraulically overloaded, handling approximately 1.2 million gallons per day while its rated capacity is 950,000 gallons per day. Refurbishing Lynn Haven's existing wastewater treatment facility would not be viable since the plant has outlived its useful life, is of a very poor design and probably could not be made to function within Departmental standards and water quality standards. The existing sprayfield does not function and results in overland flow of effluent which discharges to Class II waters. The high water table and presence of a semiconfining layer on the Lynn Haven peninsula virtually guarantee such discharges. Further, the plant only provides secondary treatment. Put simply, Lynn Haven needs another method of handling its sewage. The only remaining alternative to a Bay crossing is to tie into the existing Bay County system and any AWT wastewater treatment plant Bay County may build in the future. 8/ The existing Bay County system provides at most only secondary treatment. The Cherry Street facility, which is part of that system, functions essentially as a lift station rather than a treatment facility. The Military Point Lagoon portion of the system is nonpermitted and is operating under a consent order and has been the subject of enforcement action. The Department has an extensive agreement with Bay County requiring a significant and long term series of actions to deal with their wastewater treatment system. The modifications or improvements to the Bay County system to provide advanced treatment are not imminent and the final system conditions cannot now be determined as they will depend in large measure upon data and analysis remaining to be collected. Currently, the existing Bay County system processes a significant amount of industrial discharge and has a problem with phenols most likely due to industrial waste from two discreet industrial facilities in the County. 9/ However, all of Bay County's wastewater system problems are reasonably solvable and will be corrected in the near future, if they have not already been corrected. Additionally, the amount of sewage Lynn Haven would be sending into the current Bay County system probably would not significantly impact that system and its problems or the County's ability to solve those problems. The County is willing to accept Lynn Haven's sewage into its system and future AWT system. The connection into Bay County's system is a viable alternative currently in existence. Moreover, as indicated, Bay County has a long range plan to build an advanced wastewater treatment plant. As yet the plan remains "just a twinkle in the County's eye" and has not progressed to the design stage. However, this plan, of necessity, will eventually become reality in the next 5 to 10 years. The estimated cost to a Lynn Haven user for the Bay County conceptual system will be $25.00 per month in lieu of $15.00 for the proposed Lynn Haven system. These estimates are at best speculative. However, this cost estimate is not excessive given the fact that a Lynn Haven user lives in an environmentally sensitive area and a Bay County hook-up would eliminate the need to run a sewer pipe through food producing, Class II waters. 10/ Based on these facts, the evidence demonstrated that it was feasible for Lynn Haven to hook into Bay County's wastewater system without creating any more environmental impacts than that system is already experiencing and must solve and which, to a significant degree, have already been solved by Bay County. Given the existence of this alternative to crossing food producing waters and the fact that any future benefits are just as likely to be provided just as quickly by the County through AWT facilities, the applicant has failed to demonstrate the necessity for crossing North Bay and failed to demonstrate entitlement to a hardship variance for that crossing. Therefore, the applicant is not entitled to either a dredge and fill permit or variance for the proposed North Bay crossing.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is, recommended that the Florida Department of Environmental Regulation enter a final order issuing permit applications CS03178910, DC03178814, and 031785181, and denying the variance and permit number 031716641. RECOMMENDED this 27th day of November, 1991, in Tallahassee, Florida. DIANE CLEAVINGER Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 27th day of November, 1991.
Findings Of Fact Respondent HDR has applied to DER for a permit to construct a 60,000 gallon per day extended aeration sewage treatment plant with percolation ponds. The facility would be used to provide secondary treatment of domestic waste from the HDR Mobile Home Park. The project is in Volusia County south of the City of Oak Hill and north of the Town of Edgewater. It is bounded on the east side by the Indian River and the west side by U.S. Highway One. The mobile home project site consists of approximately 156 acres, with the proposed wastewater treatment plant located in the southwest corner of the tract. HDR submitted Application No. 85433 to DER on July 2, 1984, requesting a permit to construct a 0.6 MGD extended aeration sewage treatment plant and associated percolation ponds for the mobile home project. Supplemental information was filed with DER on August 29, 1984. DER issued a notice of intent to permit the project on November 8, 1984. The plant would provide secondary treatment of effluent with a minimum of 90 percent removal of BOD's and suspended solids through aeration, settling and chlorination processes. The system is designed to collect sewage through a gravity system and lift station. The lift station dumps the sewage into the aeration chambers where forced air is mixed with the sewage, resulting in removal of organic materials and solids. The dissolved solids are then separated in the settling tank. From the settling tank, clear effluent enters the chlorine contact chamber where chlorine disinfectant is added prior to discharge into the percolation pond. The method of treatment described above and the design of the plant are standard. If the plant is operated properly, the wastewater will meet all DER criteria for secondary sewage treatment. Plant odor will be minimized by the continual feed of forced air into the system. Silencers will be installed on blowers to minimize any adverse noise effects from the blowers' operation. Aerosol drift is not a factor with the design of this plant. Security lighting will be provided, and the plant site will be surrounded by a six foot security fence. The design provides for effluent sampling access points and there will be a flow meter for measuring effluent discharge on site. A Class C operator will be required to operate the plant. Disposal of the 90 percent treated effluent will be made into two percolation ponds. The ponds will be alternately loaded, with one pond being loaded for seven days and then resting seven days. The total surface area for the two ponds is approximately 130,000 square feet. The ponds are designed with berms of three feet with an emergency overflow one foot from the top of each berm. The two ponds together are designed to handle 200,000 gallons per day which would be the ultimate build out of this project. However, the maximum capacity of the initial phase of the wastewater treatment plant would be 60,000 gallons a day. Any expansion to the sewage treatment plant would require a separate permit. The overall elevation of the area where the ponds are to be located is approximately 14 feet above sea level. Each pond is designed so that the pond bottom is two feet above the underground water table level measured at the highest point for the rainy season. In a 100 year flood, it is expected that the effluent and water can be absorbed without an overflow. The mobile home park has a storm retention system in which any theoretical overflow would be caught. The soil type at the location of the percolation ponds consists of several layers of sands. This type of soil has good permeability in that it provides a good transfer of water through the soil and is therefore suitable for siting of the percolation ponds. Pond design is conservative in that the hydraulic loading rate has a safety factor of at least 300 percent. Once the effluent has percolated into the ponds, the discharge will meet or exceed the level of quality of the G-2 ground water within the 100 foot zone of discharge. The design of the wastewater treatment plant also includes sufficient monitoring wells and provides for adequate buffer zones from residences and drainage ditches. No surface waters of the state are located within 500 feet of the sewage treatment plant or its percolation ponds. The Indian River, which is adjacent to the Hacienda Del Rio project, is approximately 2,500 feet from the sewage treatment plant. There will be no direct discharge by the sewage treatment plant into this body of water or any surface waters, nor would any indirect effect on surface waters be measurable. Shellfish harvesting is a local industry. The waters of the Indian River immediately east of the Hacienda Del Rio property are designated Class II waters suitable for shellfish harvesting. The Indian River is also part of the Canaveral National Seashore Waters, which are designated as Outstanding Florida Waters. Concern was expressed that additional growth in the area might contribute to degradation of these Class II waters. There was, however, no evidence to indicate that the construction or implementation of the wastewater treatment plant by HCD would degrade ore pollute the Indian River (which is both Class II and Outstanding Florida Water) or any other State of Florida surface waters. It should be noted that waters north and south of the property in the Indian River are closed to shellfish harvesting, apparently due to pollution. The Town of Edgewater north of the Hacienda Del Rio project has a secondary wastewater treatment plant which discharges its effluent directly into the Indian River. The City of Oak Hill to the south of the project has no wastewater treatment plant whatsoever. Individual businesses and homes utilize septic tanks, which can cause pollution to the Indian River through seepage. The HDR sewage treatment plant would thus meet higher standards than neighboring community facilities.

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

Findings Of Fact On or about October 30, 1984, Lawrence E. Bennett, a consultant engineer for Peninsula, forwarded to DER's domestic waste engineering section an application to construct/operate a domestic wastewater treatment and disposal system along with the appropriate plans and a check for the fee. The package included proposals for construction of a 300,000 gpd splitter box and addition of a 100,000 gpd contact stabilization plant. Thereafter, on May 22, 1985, Mr. Bennett submitted a revised copy of the application pertaining to the 100,000 gpd expansion initially submitted as above. The revised application reflected Peninsula's proposed outfall to the Halifax River which was applied for under separate permit. By application dated October 7, 1983, as revised on May 15, 1985, Peninsula proposed to construct an outfall discharge into the Halifax River from the secondary treatment plant. By letter dated October 29, 1984, Mr. Bennett advised DER, inter alia, that the discharge rate would be an ADF of 1.25 mgd. The application for the additional 100,000 gpd plant and splitter box also provided for a chlorination facility. This expansion was needed because 200,000 gpd capacity is already committed to serve current residents and customers of the utility. The new construction is designed to accommodate established future demand. In Mr. Bennett's opinion, the design of this facility will accommodate all DER criteria and standards. The outfall facility proposed in the second project will be a pvc forced main for a part of the distance with iron pipe for the remainder and a lift station attached to pump the effluent to a point in the river selected where the river is deep enough to meet DER water criteria. The initial permit application on this project called for discharge into a portion of the river which did not meet water quality standards. As a result; DER suggested discharge point closer to the center of the river, and this change is now planned. At this point, the outflow will meet DER standards. Intents to issue the permits, as modified, were issued in August 1985. Peninsula has also filed for permits with the Florida Public Utilities Commission, the United States EPA, and the U.S. Army Corps of Engineers for these projects. The plans are based on the estimated population expansion called for in the next few years. Peninsula is fully capable, financially, of providing and paying for the projected improvements. In the past, it has always provided sufficient funding to do that which is called for under its permits and which is necessary. The waters in question here are Class III waters of the State, mainly recreational. There is no shellfish harvesting in the area because of the pollution of the Halifax River, condition which has existed since at least 1941. Results of tests conducted by experts for Peninsula show the quality of the water presently coming out of the treatment plant is cleaner than that currently existing in the Halifax River. The outfall pipe in question will have the capability of handling approximately 1,200,000 gpd. Latest reports from the water treatment plant indicate that the current average daily flow is 150,000 gpd representing approximately 75% of capacity. The design estimated for this project was based on a 250 gpd per unit use rate multiplied by the estimated number of units presently existing and to be constructed in the period in question. It is estimated however, that within two to three years even this project will be insufficient and Peninsula will have to file an additional request for expansion. Construction will have no detrimental environmental effect on the waters of the Halifax River. Mr. Bennett recommends discharge into the river rather than pumping the effluent backup to Port Orange because the local dissipation rate into the Halifax River, which is called for under these projects, is much quicker than that at Port Orange. Studies run on siting of the outfall pipe location which is close to Daggett Island included studies relating to dilution calculation and water quality of the effluent versus water quality of the river near the outfall. The project was, therefore, sited in such a manner as to provide for the least possible detrimental effect. Those studies, however, were for the original outfall location, not the present location as proposed by DER which is approximately 150 to 200 feet away. In the experts' opinion, however, there is very little difference in the two sites. The Daggett Island site is not unique in any way. It is a mangrove swamp of approximately 3 to 4 acres with nothing on it. Once the pipe is buried, it will be difficult to know that it is there. Even during construction, there would be little detrimental effect or disruption to the river ecology. Mr. Bennett's conclusions are confirmed by Mr. Miller; a DER engineer specializing in wastewater facility permits who has reviewed the plans for expansion of the plant for completeness and adequacy and found that they were both. The approval of the outfall pipe initially was made in Tallahassee based on the original siting. He reviewed it again, however, and determined that both projects are environmentally sound and conform to the DER standards. Rule 17-6, Florida Administrative Code, requires surface water discharge to have secondary treatment activity prior to discharge and the discharge cannot exceed 20% 80D and suspended solids. According to DER studies; the secondary treatment afforded the water at this location was adequate with the caveat that the District might want to require an extension of the outfall to the main channel of the river to promote tidal flushing of the effluent. It was this change which was; in fact, made by the District office. Without the change, the incoming tide would take the wastewater up into Daggett Creek. By moving it as suggested, west of the point of Daggett Island, the tide would go up river rather than into the creek taking the effluent with it. Concern over the creek is due to its limited natural flushing as opposed to the greater natural flushing of the river. It was the intent of all parties to achieve the desired result and move the outfall point; if at all possible, at no increase in cost. Consequently, the pipeline was moved at the same length with a slight possible addition to take the outlet to the same depth and this change became a condition to the issuance of the permit. The Peninsula will also need a dredge and fill permit in order to accomplish the work in question. The outfall plans (both construction and discharge) meet the requirements set forth in the pertinent provisions of Rule 17-6, Florida Administrative Code. DER evaluated post- construction, concluding that the new point source discharge would not violate these standards. However, prior to approval of these projects, DER did not perform a biological, ecological, or hydrographic survey in the area. As a result, it cannot be said that the criteria outlined in Rule 17-4.29(6), Florida Administrative Code, will not be adversely affected by the outfall pipe. Nonetheless, these surveys were not deemed necessary here. EPA denial of the NPDES (National Pollution Discharge Elimination System) permit, would have no impact on DER's intent to issue the instant permits. NPDES permits have no bearing on the state permitting process. If the NPDES permit is denied, the utility cannot discharge its effluent into the river. The state permit merely authorizes the construction. The NPDES permit applies to the outfall portion of the project, not to the treatment plant. Only if it could be shown there was a longstanding adverse effect on the water quality so as to bring it below standards, would this construction not be permitted. The depth of the water in the proposed area of the outfall is five feet. A 12-inch pipe would extend below the soil with an upturn to exit into the bottom of the river. Short term impacts of actual construction are not relevant to the permitting process. If there are any, they would be related to and considered in the dredge and fill permitting process. This conclusion is supported by the testimony of Jan Mandrup-Poulsen, a DER water quality specialist who, in his analysis of the instant projects, first looked at the plans for the outfall just a week before the hearing. By this time, the water quality section of DER had previously considered the project and he is familiar with the suggested change in the outfall location. In November 1985, he spent several days on a boat on the Halifax River in this area collecting data. His inquiry and examination showed that in the area in question, there are no grass beds, oyster beds, or anything significant that would be adversely affected by the location of the pipe and the outlet. The pipe outlet, as suggested, is far enough out into the river to keep it under sufficient water at all times to promote adequate flushing. In his opinion, the proposed discharge will be quickly diluted and will not violate the standards or other criteria set out in Section 17-3.121, Florida Administrative Code. In contrast to the above, Mr. Richard Fernandez, a registered civil engineer with a Master's Degree in environmental engineering, who did a study of these projects for TPI, indicated that the County 201 plan relating to this area, mandated by the federal government, calls for the eventual closing of all independent wastewater treatment plants with ultimate delivery of all wastewater to the Port Orange facility. If implemented, this plan calls for the conversion of the Peninsula facility to a pump station for the transmittal of effluent to Port Orange. In his opinion, the proposed discharge standard, as evaluated here, for the secondary treatment facility, is very high for such a facility. He feels the surface water discharge content of dissolved oxygen and suspended solids should be lower. In addition, he is of the opinion that the degree of treatment of discharged water required by the facilities in question here is too low and lower than typical secondary discharge points elsewhere in the area. Nonetheless, Mr. Fernandez concludes that while the intended facility here would probably not lower the quality of river water below standards, it is not in the public interest to construct it. Having considered the expert testimony on both sides, it is found that the construction requested here would not create sufficient ecological or environmental damage to justify denial. The proposals in the 201 plan calling for the transmittal of all effluent to Port Orange would not be acceptable to DER. The cost of such a project and the ecological damage involved would be so great as to render the project not even permittable. The currently existing percolation ponds used by the facility at Port Orange are not adequate to serve current needs and leech pollutants into the surrounding waterway. While the exact transmission routes called for under the 201 plan are not yet set, there would be substantial ecological problems no matter what routing is selected. There would be substantial damage to bird habitat, mangrove, and other protected living species unless some way were found to get the pipe across the river in an environmentally sound fashion. Consequently, DER has taken the position that the current proposals by Peninsula are superior to any plan to transmit waste to Port Orange.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is, therefore RECOMMENDED THAT DER: Enter an order dismissing with prejudice Volusia County's Petition in DOAH Case No. 85-3029 and, Issue permits to Peninsula Utilities, Inc., for the construction of a 100,000 gpd expansion to its existing wastewater treatment plant and to construct a river outfall line as was called for in the amended specifications listed in the application for this project.

Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant facts are found: Petitioner L. C. Prevatt is the owner and operator of the Riverview Speed Wash, Inc., a coin operated laundry which has been in existence for over ten years. The facility has twelve top load washers, four double load washers, one triple load washer and seven gas dryers. It is open from 7:00 a.m. to 9:00 p.m., seven days a week. The facility is located in a shopping center in space which petitioner rents on a month-by-month basis. The facility utilizes a 0.0075 mgd waste treatment plant with effluent disposal to a county-owned drainage ditch which is connected and discharges to the Alafia River approximately 0.6 miles south of the facility. On or about May 29, 1981, petitioner submitted an application for a temporary operation permit for his Riverview laundry facility. Temporary operation permits are issued by the DER when a facility is not currently meeting State water quality standards and the applicant needs or desires a period of time to bring the facility up to the applicable standards. Here, the petitioner stated on his application that no upgrade of the waste treatment facility was planned. The application further stated that the facility would be connected to an area wide regional waste treatment system when that system became available. After numerous requests for further information from the applicant and various inspections of the facility, the DER issued its notice of intent to deny petitioner's application for a temporary operation permit. Reasons for the intended denial included failure to provide requested background water quality information, failure to provide a proposed water quality standards compliance schedule, failure to provide reasonable assurance that a municipal sewer would be available as an alternative means of disposal and improper and deficient operation and maintenance of the facility. Numerous inspections of the petitioner's facility by personnel from the DER and the Hillsborough County Environmental Protection Commission revealed that the facility was not functional in terms of operating correctly and that the design of the plant was inadequate to meet State water quality standards. Specifically, these inspections revealed that the chlorination equipment was not operational, that the trickling filter was not operational, that the removal rates for BOD and suspended solids were consistently and significantly less than the State standard of 90 percent, that the discharge and effluent were of a milky color and would not meet the State standards for turbidity and color, that the water quality of the drainage ditch was extremely low and that the water quality results were actually worse after going through the existing system. It was determined that the discharge was degrading the quality of the receiving waters and that, even if the petitioner's operational and maintenance problems were solved, the design of the facility is not adequate to assure future compliance with State standards. Petitioner admits that his facility does not currently meet State water quality standards. In mitigation, it is contended that many other laundries in the area also do not meet State standards, that it is not economically feasible to redesign the facility to attain compliance, that he has no land available upon which to discharge effluent and that he would be willing to install a sand filter and did have the permission of the manager (not the owner) of the property to discharge effluent into the parking lot drain ponds. No written evidence of this agreement was adduced and there was no demonstration that such runoff ponds would be able to hold and/or treat effluent from the petitioner's facility. There was also no evidence offered to demonstrate that a municipal or regional sewer system would be available in the near future to serve the laundry facility.
Recommendation Based upon the findings of fact and conclusions of law recited above, it is RECOMMENDED that petitioner's application for a temporary operation permit for Riverview Speed Wash, Inc. be DENIED.
