Findings Of Fact The Petitioner is a special tax district created by special act of the Florida Legislature. Chapter 71-822, Laws of Florida. The district covers approximately seventy-two square miles in northern Palm Beach County and southern Martin County, Florida. Petitioner's purpose is to provide water, sewer, drainage and solid waste services within the district. In conformity with its powers, the Petitioner operates an advanced waste water treatment plant on property which it owns in northern Palm Beach County. Petitioner has secured appropriate permits from DER in order to construct and operate the treatment plant. The treatment plant is among the most advanced in southeastern Florida. It has a four million gallon daily capacity, which could be increased to an eight million gallon capacity. In treating waste water the plant utilizes filtration, disinfection, retention in a holding pond, and discharge into a remote off-site area. The present discharge system is to pump effluent from the retaining pond through a canal or drainage system to a recharge or discharge lake which is located approximately three miles north and west of the treatment plant. This is known as the western discharge system, and was installed at a cost of approximately one million dollars. Due to the large amounts of pumping activity, it is an expensive system to utilize. Through its instant application, the Petitioner is seeking a permit allowing it to discharge effluent on-site. Effluent would flow into percolation ponds that have already been constructed. Effluent would settle in the ponds, and eventually would percolate through the soil. This system would he less expensive to operate than the western discharge system. Petitioner is interested in experimenting with the amount of waste water treatment that can be obtained through action of vegetation in the percolation ponds upon the effluent. Such a natural system, if it operated effectively, could save the Petitioner additional money in treating waste water by reducing the need for chemical treatment. Petitioner's waste water treatment presently results in a discharge of effluent which within some parameters meets even drinking water standards. The Petitioner's system very effectively treats bio-chemical oxygen demand ("bod"), suspended solids, nitrogen, and phosphorus in the effluent. Reports have been submitted by the Petitioner to DER which indicate that the system does not meet DER's standards for advanced waste water treatment. Samples upon which these reports were based were taken at a point in the system before the effluent was subjected to the action of the retention pond and the subsequent bumping into the western discharge system. Samples taken beyond the retention pond indicate that DER's standards are met for "bed", suspended solids, total nitrogen, and total phosphorus. The Intervenor owns property adjacent to the Petitioner's waste water treatment plant. The Intervenor operates a well field and drinking water treatment plant on the property, and provides drinking water to residents of the Town of Jupiter and surrounding communities from the well field. The Intervenor acquired its treatment plant, and surrounding well fields from a private utility company. The Petitioner was aware of the well field when it purchased the property upon which it presently operates its waste water treatment plant. While the Petitioner's plant adequately treats waste water in terms of "bod", suspended solids, total nitrogen, and total phosphorus it does not treat the waste water for heavy metals, pesticides, or viruses. These are common elements found in waste water effluent in the south Florida area. The Petitioner's proposal is to discharge its effluent into on-site ponds. The effluent would then percolate into the ground. The retention ponds are located at a distance from 1200 to 1600 feet from the nearest of the Intervenor's wells. Water which percolates from these ponds would flow directly toward the wells, and would eventually find its way into the wells. The flow from the retention ponds to the wells would be increased due to the draw-down effect that the wells have on the surrounding water table. As water is drawn from the wells, the adjoining water table becomes depressed in the area of the wells, and water from the surrounding area flows more rapidly into the area of the wells. Heavy metals will not be filtered out as a result of retention or percolation. Heavy metals in the effluent would eventually find their way into the Intervenor's well fields. Estimates as to the amount of time that it would take for water from the percolation ponds to reach the wells varied from four months to six years. The longer estimate appears the more reasonable; however, the evidence is conclusive that eventually waters from the percolation ponds would reach the wells, and that heavy metals in the water would not be filtered out. The Petitioner proposes to obviate any problems with heavy metals reaching the well fields by operating testing wells between the percolation ponds and the well fields. If any heavy metals were detected in the ground water, Petitioner would again use the western discharge system rather than the percolation ponds. While this would prevent increased contamination of the wells, contamination that had already reached the test wells would reach the Intervenor's wells. It was suggested that the percolation ponds could be drawn down in order to reverse the flow of ground water back into the percolation ponds, thence to be pumped through the western discharge system. In order to accomplish this, however, the percolation ponds would have to be more than forty feet deep, which they are not. The effect of heavy metals intruding into the Intervenor's water supply could be to increase the cost of treatment, or to render the wells unfit for use. Uncontaminated drinking water supplies are rare in the northern Palm Beach County area, and the expense of finding a new water supply is difficult to calculate.
Findings Of Fact The permit Applicant and Co-Respondent, Florida Medical Facilities, Inc. is the owner and developer of a 60-acre tract of land upon which it has constructed a hospital and will construct various attendant laboratories, medical offices and the like. Additionally, the Applicant is the owner of approximately five acres of land adjacent to its original 60-acre site which lies on Morningside Drive in Englewood, Sarasota County, Florida. The Applicant proposes to construct and operate the wastewater treatment plant on that 5-acre parcel. The Applicant proposes to construct an extended aeration wastewater treatment plant and effluent disposal drain field system which will accommodate and dispose of all wastewater effluent on the site by the absorption bed, land application method. The proposed sewage treatment plant will have an average daily design flow capacity of 50,000 gallons per day. The anticipated peak flow of the treatment plant will be 60,000 gallons per day. The plant will generate and dispose of approximately 900 gallons of waste sludge on a daily basis. The facility would employ dual drain fields, use of which would be rotated on a weekly basis. The proposed average hydraulic loading rate would be 3.21 inches per day or two gallons per day, per square foot of drain field. The proposed facility will serve a 100-bed community hospital, assorted medical offices, a diagnostic laboratory and a 75-bed nursing home. The permit applicant has agreed and stipulated that chemical, nuclear and other hazardous and noxious waste materials, blood, body parts, medicines, and drugs will not be introduced into the sewage treatment system plant or drain fields. The Applicant (FMF) originally proposed to dispose of sewage effluent emanating from its hospital and other facilities by transmission of it through force-mains to existing public wastewater systems, one of which is in Charlotte County and the other in Sarasota County. After exploring these possibilities, these alternatives proved to be either too expensive or to involve transmission of effluent over too great a distance to make these options feasible. Sarasota County has a local pollution control program approved by the DER, pursuant to Section 403.182, Florida Statutes. Under this program the Sarasota Environmental Service Department reviews domestic wastewater treatment facility permit applications pending before the DER and makes recommendations on their disposition. The county's ordinance concerning such facilities is equivalent to the DER standards, except in some respects it is stricter Mr. Russell Klier of the county environmental services department established that the proposed project as planned and designed, will comply with county ordinances regarding wastewater treatment plants. Indeed, it was established through Mr. Klier's testimony, that the proposed project has more redundancy and reliability safeguards than any other such project presently operating in Sarasota County. The proposed sewage treatment plant and disposal system is designed to attain the secondary level of treatment required by Chapter 17-6.060, Florida Administrative Code. The effluent disposal system will provide for disposal of effluent in an absorption field system as envisioned by Chapter 17-6.040(4)(M), Florida Administrative Code and the Department's "Land Application Manual," incorporated by reference in that rule. The system, as proposed, will have the additional safeguards required by the "Land Application Manual" in order to attain "Class I reliability." The hospital, which is the initial facility to be constructed on the 60-acre site, is largely completed, and is being served by a temporary "package" sewage treatment plant until the permit application is resolved. The package sewage treatment plant, as well as the proposed plant and drain field land application system will only serve the medical center complex. All on-site stormwater and surface water run-off from both the 60-acre original medical center site, as well as the 5- acre proposed sewage treatment plant and disposal site, will be managed by directing stormwater and surface water run-off to holding ponds to be constructed and maintained on the original 60-acre site. Steven Houghton was accepted as an expert engineering witness. It was thus established that the system as designed will meet all water quality parameters regulated and enforced by the DER and Sarasota County in terms of the quality of the effluent generated by the plant and disposal system for disposal by land application. In this connection, he established that no nuclear, infectious, toxic or noxious waste will be processed by the system or introduced into the system nothing other than domestic-type sewage will be treated, processed and disposed of by the proposed system. Mr. Houghton acknowledged that the project will be located in an historically flood-prone vicinity, but that will not affect the quality or effectiveness of the operation of the plant nor the safe disposal of the resulting effluent. In that regard, the Applicant will place fill at the drain field site so as to provide a more effective soil percolation condition than that presently existing in the soils at the drain field site. Additionally, the Applicant will provide a sewage storage tank to provide extra reliability and avoidance of pollution caused by sewage overflows in the event of any excessive sewage flows into the plant, and as a safeguard against disposing of insufficiently treated effluent during periods of high rain and high surface or ground water conditions. Additionally, the system will be constructed and operated with sufficient redundancy of electrical and mechanical components so as to provide auxiliary capacity throughout the system, allowing it to operate efficiently 24 hours a day and to continue to provide treatment and disposal of the effluent in accordance with secondary treatment and Class I reliability standards, even during periods of mechanical or electrical outages. Petitioner Mary Wagoner owns and resides on acreage generally south and adjacent to the proposed project site. Mrs. Wagoner uses a potable water well in the shallow aquifer with a depth of approximately 35 feet. Mrs. Wagoner's well has recently been tested and at this time provides good, safe, potable water which she uses both for drinking, cooking, domestic usage, as well as water for her livestock. Mrs. Wagoner's well is less than 500 feet from the proposed "wetted area" of the drain field land application disposal site. Mr. Edward Snipes was accepted and testified as an expert witness in the areas of engineering and wastewater engineering on behalf of the Department. He corroborated Mr. Houghton's testimony in establishing that the project would meet the Department's standards for water quality and Class I reliability in large part. It was shown that the project will not likely have harmful effects on the Petitioners' water wells. Mr. Snipes established that the Department's "Land Application Manual" embodied in Rule 17-6.04(4)(Q), Florida Administrative Code requires a buffer zone of only 100 feet, instead of 500C feet, from the wetted area of the sewage effluent disposal site, due to the type of system and level of treatment proposed. That is, the system would provide secondary treatment, with additional safety measures incorporated in the design and operation so as to achieve Class I reliability. This Class I reliability standard includes a sufficiently high rate of disinfection so as to allow unrestricted public access to the site, and thus would meet the most stringent Class I reliability standards extant in Rule 17- 6.040(4)(M), Florida Administrative Code. This permits a reduced buffer zone between the wetted area of the drain field and any adjacent, shallow-water wells. Thus, the buffer zone would, in the case of this plant, be allowably reduced from 500 feet to 100 feet. In only one respect, was any doubt cast by Petitioner's testimony and evidence on the showing of reasonable assurances that all Department water quality and wastewater treatment standards will be met. That doubt concerns the distance from the bottom of the drain field to the water table elevation at the drain field site, as that relates to the ability of the system to continue to treat and dispose of effluent within appropriate standards in this admittedly flood-prone area, as that problem would in turn relate to potential contamination of ground water in the area, especially in times of high rainfall and high ground water levels. In that connection, Petitioner Wagoner offered Herman Weinberg as an expert witness in civil engineering and he was accepted. Mr. Weinberg acknowledged that he was not a soil engineer and acknowledged that the Department or its witnesses were more knowledgeable about wastewater regulation, treatment and disposal methods than he. He opined, however, that the plant may not be able to reach Class I reliability due to its location in a flood-prone area. He fears that insufficient soil testing and water quality testing had been done prior to the filing of the permit application. and prior to the ultimate construction of the project, if that is to be the case. Section 17-6.040(4) (M), Florida Administrative Code, adopts by reference the United States Environmental Protection Agency design criteria for mechanical, electrical and fluid system and component reliability manual. That manual sets forth certain minimum standards for Class I reliability sewage treatment and disposal plants and systems. In this regard, the rule in that manual establishes that wastewater treatment works include holding ponds and basins and other structures of the disposal system. It provides that all treatment works, structures, as well as electrical and mechanical equipment, shall be protected from physical damage by flooding of a magnitude occurring on the average of once in a hundred years, the so- called "100-year flood." In this connection, it was established through witness Weinberg's testimony as well as that of Mr. Houghton, the Applicant/Respondent's witness, that the 100-year flood plan elevation on and around the subject site is 12 feet above mean sea level. The top of the proposed drain field would be located at 12.33 feet elevation. The bottom of the drain field would be at 10.33 feet elevation. The water table level established by witness Houghton as a result of his survey and calculations, is at 8.33 feet elevation. The Department of Environmental Regulation, in its "Land Application Manual," which provides criteria for sewage plant and disposal system construction and operation, requires a 36-inch minimum separation between the bottom of a drain field and the design water table level. Thus, the legally operative Class I reliability standards, incorporated in the above-referenced rule and manuals, and which the Applicant and the Department agree is the level of reliability required, given the conditions and the proximity of Petitioner's well, can only be met if the drain field disposal system is at this required elevation of 36 inches above the design water table level. Affirmative, reasonable assurances that this safeguard will be incorporated in the subject system are necessary in view of the fact that Petitioner Wagoner's potable water well is clearly less than 500 feet from the wetted area of the drain field site. In this connection, the Applicant/Respondent has proposed placing fill soil of a suitable type for adequate percolation and land application treatment of the effluent on the drain field site, however, it has not been established that this will be done to such an extent as to raise the elevation of the drain field sufficiently so that the bottom of the drain field is a minimum of 36 inches above the design water table. The installation of an adequate depth of fill soil of a suitable percolation characteristic must therefore be a condition on the issuance of the permit. Further, in that regard, the Applicant/Respondent's soil test and calculation of tile ground water level or "design water table," occurred in January and February of 1985, at a time when the southwest region of Florida was in a drought or dry condition, such that the water level or ground water table at normal rainfall conditions would likely be at a higher elevation. Thus, a grant of this permit must be conditioned upon the installation of sufficient, appropriate quality fill soil to ensure that the minimum 36-inch separation between the drain field bottom and the water table is maintained during normal water table or rainfall conditions. If this measure is not taken, given the 2-foot separation between the drain field, as designed, and the water table, the oxygen transferring capacity of the soil beneath the drain field may not be sufficient to satisfy the oxygen demand required for consistently adequate treatment and safe disposal of the sewage effluent. Additionally, in this same context, Chapter 1 of the DER Land Application Manual at Section 1.3, requires that sufficient storage capacity exist on-site to ensure retention of sewage effluent during conditions which preclude land application, such as high ground water conditions or flooding conditions. This capacity should be equivalent to three days maximum daily flow at the design capacity of the plant, or in this case, 180,000 gallons. Although the Applicant, by its plans and specifications in evidence, has assured that a sewage effluent storage tank will be constructed and operated, it has failed to establish that sufficient storage capacity will be incorporated to assure the retention of 180,000 gallons of effluent. Any grant of the permit application should be conditioned upon such an assurance. Finally, in connection with the above-mentioned condition concerning installation of sufficient, appropriate soil filling to allow for a minimum 36-inch amount of unsaturated soil beneath the drain field, that addition of fill should also be of a sufficient type and amount to ensure that the Applicant's proposed rotation or "resting" of drain fields for 7-day periods will be adequate to ensure that the subject amount of soil is unsaturated before re-use of either of the two drain fields. There should be incorporated in these conditions, upon a grant of the permit, the requirement that the Department monitor construction of the proposed facility to ensure that the above conditions are adequately met, in view of the low-lying terrain at the drain field site and the flood-prone condition of that locality. Petitioner Mary Nygaard testified on behalf of herself and her husband, Lyle A. Nygaard. Mrs. Nygaard complains of feared pollution of her shallow-water potable well which she maintains is within 500 feet of the drain field and sewage plant site. Mr. Nygeard established that the well is 187.1 feet from the Petitioner's southern property boundary, but acknowledged that no survey has been done delineating the distance to the proposed wetted area of the drain field. It was not otherwise proven how far the Nygaard's potable well is from the wetted area of the proposed drain field where the effluent will be disposed of. Various easements and roadways lie between the Nygaard's well and the wetted area of the proposed drain field site with indeterminate dimensions, thus it was not proven what distance exists between the Nygaard's well and the drain field site other than that it exceeds 187.1 feet.

The Issue There are two issues in these cases: (1) whether Tampa Bay Desal, LLC ("TBD") provided reasonable assurances that its permit application to discharge wastewater from a proposed seawater desalination plant, National Pollutant Discharge Elimination System ("NPDES") Permit Application No. FL0186813- 001-IWIS, meets all applicable state permitting standards for industrial wastewater facilities; and (2) whether Tampa Electric Company, Inc. (TEC) provided reasonable assurances that its proposed modification to an existing industrial wastewater facility permit, NPDES Permit Modification No. FL0000817-003-IWIS, meets all applicable state permitting standards.
Findings Of Fact Parties other than SOBAC Poseidon Resources, LLC wholly owns TBD as one of Poseidon Resources' subsidiaries. Poseidon Resources formed TBD, the successor to S&W Water, LLC, as a special purpose project company to properly staff and finance the desalination project. TBW entered into a 30-year purchase agreement with TBD (then known as S & W Water, LLC) in 1999 to build, own and operate the desalination facility. Poseidon Resources operates as a privately-held company and all stockholders are major corporations. Poseidon Resources opened for business in 1995 and has over $300 million in water processing assets under management. DEP is an agency of the State of Florida. The United States Environmental Protection Agency ("EPA") delegated its NPDES permitting program to the State of Florida and is run by DEP. TEC is an investor-owned electric utility serving Hillsborough, Polk, Pasco, and Pinellas Counties. TEC owns and operates the Big Bend generating station, an electric plant consisting of four coal-fired steam units having a combined capacity of approximately 1800 megawatts. SWFWMD is a water management district in the State of Florida. SWFWMD reviews and acts upon water use permit applications and protects and manages the water and water- related resources within its boundaries. TBW and all of its Member Governments are within the geographical and legal jurisdiction of SWFWMD. Pasco County is a political subdivision of the State of Florida, a member government of TBW, and is located within the jurisdiction of SWFWMD. Pasco County is a major source of the groundwater used by TBW. TBW is a regional public water supply authority. TBW is the sole and exclusive wholesale supplier of potable water for all its member governments of TBW, which are Hillsborough County, Pasco County, Pinellas County, the City of New Port Richey, the City of St. Petersburg, and the City of Tampa. TBW serves approximately 2 million customers. SOBAC SOBAC was incorporated as a Florida not-for-profit corporation in February 2000. The stated mission of SOBAC is to protect the environmental quality of the bays, canals, and waterways of the Tampa Bay area, and to ensure drinking water for SOBAC members in the Tampa Bay area. SOBAC was formed by a group of people residing primarily in the area of Apollo Beach. Apollo Beach is a waterfront residential community that was created by dredge and fill of wetlands, estuary, and bay bottom bordering the "Big Bend" area of Tampa Bay, where the community terminates in a "hammerhead" of fill over what was once a seagrass bed. Across the North Apollo Beach "Embayment," formed by the "hammerhead," is the discharge canal of TEC's Big Bend power plant. A corrugated metal barrier partially separates the embayment from the discharge canal. This discharge canal also will receive TBD's discharge after re-mixing with TEC's discharge. SOBAC initially was formed out of concern for the environment in the Big Bend area of Tampa Bay. However, there is no requirement that SOBAC members live in the Apollo Beach area, or even in the vicinity of Tampa Bay, and SOBAC's geographic area of concern has broadened somewhat beyond the Apollo Beach area. In order to become a member of SOBAC, one need only sign a card. Prospective members are asked to donate $5 on signing up. Most members donate $5 or more. However, the donation is not mandatory. There is no requirement that members attend any meetings, or participate in any SOBAC activities. Section 3.1 of SOBAC's Constitution and Corporate By-Laws makes "active" membership contingent on payment of "the prescribed [annual] dues." Section 3.2 of SOBAC's Constitution and Corporate By- Laws requires SOBAC to establish annual dues, but no annual dues have been paid because no annual dues structure has ever been established. As a result, no annual dues have been "prescribed," and "active" membership does not require payment of annual dues. SOBAC claims to have approximately 1,000 members. These include all those who have ever become members. Approximately 700 live in the Appollo Beach area; approximately 50-75 of these members form the "core" of active members. Approximately 50-100 members live outside the Tampa Bay area; some of these outsiders probably are among the approximately 100 who are members by virtue of SOBAC's reciprocity agreement with another association called "Friends of the River." SOBAC has never surveyed its membership to determine how its members actually use Tampa Bay. However, the evidence was sufficient to prove that a substantial number of its members, especially among those who reside in the Apollo Beach area, enjoy use of the waters and wetlands of the Big Bend area for recreational activities such as boating and fishing. For that reason, if the activities to be permitted by DEP in these proceedings were to cause environmental damage, a substantial number of SOBAC's members would be affected substantially and more than most residents of distant reaches of the Tampa Bay area. Background of Desalination Project In 1998, the predecessor agency to TBW (the West Coast Regional Water Supply Authority), the six Member Governments and SWFWMD entered into an agreement specifically addressing impacts to natural systems through the development of new, non- groundwater sources, and the reduction of permitted groundwater withdrawal capacity from TBW's eleven existing wellfields from the then permitted capacity of 192 million gallons per day (mgd) to 121 mgd by December 31, 2002 (the "Partnership Agreement"). Pursuant to the Partnership Agreement, the existing water use permits for TBW's 11 specified wellfields were consolidated into a single permit under which TBW is the sole permittee. Prior to execution of the Partnership Agreement, the existing permits for these 11 wellfields allowed for cumulative withdrawals totaling approximately 192 mgd. Upon execution of the Partnership Agreement, the consolidated permit immediately reduced allowed withdrawals to no more than 158 mgd and required that wellfield pumping from the 11 wellfields be further reduced to no more than 121 mgd by December 31, 2002, and then to no more than 90 mgd by December 31, 2007. These withdrawal reductions are necessary to reduce the adverse environmental impacts caused by excessive withdrawals from the 11 wellfields, the majority of which are located in Pasco County. In order to replace the reduction of groundwater withdrawals, TBW adopted a Master Water Plan that provides for the development of specified new, alternative sources of potable water. The seawater desalination facility ("Desal Facility") is one of the cornerstone components of the Master Water Plan. This Facility will furnish 25 mgd of new water resources for the Tampa Bay area and must be in service by December 31, 2002, in order to meet the potable water needs of the residents of the Tampa Bay area. In exchange for the groundwater withdrawal reductions, SWFWMD agreed to contribute up to $183 million towards the development of new water sources that are diverse, reliable and cost-effective. SWFWMD has agreed to co-fund up to 90 percent of the capital cost of the Desal Facility. To comply with the terms and conditions of water use permits it has received from SWFWMD for other water withdrawals in the region, TBW must increase the water sources from which it withdraws water for distribution to its Member Governments in a timely manner. The Desal Facility is the essential means by which these permitting requirements can be met. For the past two years, the Tampa Bay area has been experiencing historic low rainfall and drought conditions. The Desal Facility is supported not only by TBW and its Member Governments, but also by SWFWMD since it is a drought-proof source of supply which has the greatest ability of any new water supply source to allow TBW to meet its members' potable water supply needs while also reducing pumpage from the existing 11 wellfields. In addition to its being a drought-proof source of potable water supply, the Facility will also provide diversity and reliability for TBW's sources of supply, and is a source that is easily expandable to provide additional potable supply that may be necessary in the future. Prior to deciding to proceed with a desalination project, TBW conducted four separate studies to look at the potential individual and cumulative impacts of a desalination facility on Tampa Bay and the surrounding areas, and in particular to evaluate the changes in baywide salinity due to the desalination discharge alone and in combination with the river withdrawals occasioned by other projects. Commencing in 1997, TBW conducted a procurement process that culminated in the award in July 1999 of a contract to S & W Water, LLC, now known as Tampa Bay Desal, LLC, to design, build, own, operate, and eventually transfer to TBW a seawater desalination plant to provide potable water to Hillsborough, Pinellas, and Pasco Counties and to the Cities of Tampa and St. Petersburg for 30 years. TBD's Desal Facility is co-located with the Big Bend Power Station owned and operated by TEC on the northeast side of Hillsborough Bay, in Hillsborough County, Florida. By discharging the concentrate from the Desal Facility to the power plant cooling water prior to its discharge to the power plant discharge canal, environmental impacts from the concentrate are minimized, and disturbance of the discharge canal is avoided. The costs avoided by utilizing the existing intake and outflow from the TEC power plant are reflected in the lower cost of the water to Tampa Bay Water, and ultimately its Member Governments. TBW is contractually bound to TBD to purchase all of the potable water that is produced by the Desal Facility for distribution to its Member Governments and to purchase the entire Facility in the future. With the exception of the NPDES permit at issue, TBD has obtained all of the over 20 other permits which are required for the construction and operation of the desalination facility. TBD has already invested approximately $20 million in this project. The total estimated capital cost of the desalination facility is $110 million. TBD has obtained financing of $42 million and expects to acquire permanent financing in the month of October 2001. SWFWMD agreed to subsidize up to 90 percent of the capital cost of the desalination facility payable to TBW over the term of agreement with TBD. TBD is contractually bound to TBW to complete and fully operate the desalination facility by December 2002. TBD Desalination Process Overview of Process In the instant case, desalination is performed through reverse osmosis ("RO"), a mechanical process wherein pretreated water under very high pressure is pressed against a very fine membrane such that only pure water can pass through it. The vast majority of salt molecules and other substance are eliminated from the water. The RO process is not heat or chemical driven. No additional heat load is being added as a result of the desalination discharge, and the desalination plant will actually result in a reduced heat load to the bay. The desalination facility will withdraw approximately 44.5 mgd of raw water from Units 3 and 4 of TEC's Big Bend cooling water system, produce approximately 25 mgd of product water for transmission to the regional water supply system, and discharge approximately 19.5 mgd of clarified backwash and concentrate water equally into each of the power plant cooling water tunnels for dilution and release into the discharge canal. During abnormal power plant operations including times when Units 3 or 4 are not in operation and during the summer months when the normal supply water intake temperature exceeds the operating temperature range of the RO membranes, a portion of the source water will be withdrawn from an auxiliary supply water system. The auxiliary supply water system consists of a supply pump and pipeline that withdraws water from a location downstream of the fine-mesh screens for Units 3 and 4. The total combined bay withdrawal flow for the power plant and the desalination facility cannot exceed 1.40 billion gallons per day ("bgd"). This limitation ensures that entrainment does not exceed the levels previously permitted for the site, and a new entrainment study pursuant to Section 316(b) of the Clean Water Act is not required. Pretreatment Process The desalination intake water is pretreated in a two- stage gravity filtration process with chemical additives. During pretreatment, ferric sulfates will be added to the desalination intake water to coagulate and capture suspended solids, organic material, and metals that exist in the raw water supply. In this first stage of the pretreatment process, the intake water runs through an aerated course sand filter. Aeration enhances the coagulative process and assists in the capture of organics, suspended solids, and metals. Aeration also occurs in stage two, which uses a fine sand filter pretreatment process. The backwash water from stage two recirculates to the stage one treatment process. The pretreated waters exits through a five micron cartridge filtration prior to entering the RO process. The aerated pretreatment filter backwash water from the pretreatment stage one pretreatment will be sent to a discharge sump for initial settling and then to a clarifier and filter press to remove excess water. Approximately 14 wet tons a day which includes organics, suspended solids, and metals that are removed through the coagulative process and captured from the gravity filters are removed off-site to a landfill. The desal concentrate and clarified backwash water will be combined in a discharge sump or wet well prior to entering into a discharge line manifolded to equally distribute the concentrate discharge into all of the available cooling water outflow tunnels or conduits of the power plant discharge. Reverse Osmosis Membrane Treatment The RO desalination process consists of a two-stage pass of the pretreated water through the reverse osmosis membranes. The RO pumps will force the water through the RO membranes at pressures ranging from 600 to 1000 pounds per square inch (psi). As a result of the RO process, approximately 25 mgd of purified water, also known as permeate, will be produced for delivery to TBW. TBD anticipates cleaning its membranes twice per year, perhaps less, due to the high level of pretreatment. Periodic cleaning removes silt and scale from the membrane surface. Dilute solutions of citric acid, sodium hydroxide, sulfuric acid, sodium tripolyphosphate, or sodium dodecyclbenzene compromise the constituents of various cleaning solutions, with the actual cleaning solution used dependent upon the actual performance of the system once it is placed in operation. Once the cleaning cycle is complete, the spent cleaning solution will be purged from the feed tank, membrane vessels, and piping and diverted into a scavenger tank for off- site disposal. Clean product water (permeate) will be fed to the feed tank and pumped into the RO membrane vessels. This process will continue until the pH of the purge water meets the Class III marine water quality criteria. The membranes will be rinsed with brine concentrate and permeate, and the rinse water will be directed to the wet well for discharge, with the concentrate into the TEC cooling water stream. TBD determined the chemical characterization of the membrane cleaning solution discharge. Cleaning solutions are not discharged in detectable concentrations. As further assurance, the permit requires toxicity testing immediately after membrane cleaning. Dilution of Discharge Water Co-locating the desalination facility with TEC's Big Bend power station allows the desalination concentrate to be diluted with TEC's cooling water prior to discharge into Tampa Bay. The point of injection of the desalination discharge will be located approximately 72 feet upstream of the point of discharge to the discharge canal to ensure complete mixing of the desalination concentrate with TEC's cooling water. This provides reasonable assurance that the desalination discharge will be completely mixed within the cooling water conduits. If all four TEC units are in operation and TBD is producing 25 mgd of finished water, the approximate dilution ratio of the desalination concentrate with TEC cooling water is 70:1. Historical TEC data indicates that a dilution ration of greater than 20:1 will occur more than 99.6 percent of the time, and a dilution ration of greater than 28:1 will occur more than 95 percent of the time. The dilution limitations in the proposed permit are more stringent than those required in Rule 62-302.530(18). The permitted dilution ratio complies with Rule 62- 660.400(2)(d) because it takes into account the nature, volume, and frequency of the proposed discharge, including any possible synergistic effects with other pollutants which may be present in the receiving water body. Comparisons of the Antigua, Key West, and Cyprus facilities are not applicable because those desalination facilities lack the initial dilution that will exist at TEC's Big Bend site. The proposed permit requires a 20:1 minimum dilution ratio at any given time, which may occur for no more than 384 hours per calendar year, and with the further limitation that the discharge at the 20:1 minimum dilution ratio shall not exceed 384 hours in any given 60-day period. At all other times, a minimum dilution ratio of 28:1 must be maintained. To ensure proper dilution and system operation, computer instrumentation in the desal facility will interface with TEC to continuously monitor the operations of TEC's four cooling tower condenser units. If any of the pumps shut down, an alarm will sound at the desalination facility and the computer system will automatically shut down the concentrate discharge to that specific condenser unit discharge tunnel. Further, the desalination plant will employ approximately 12 employees, with a minimum of two employees on duty at all times. TEC Permit Modification Big Bend power station has four coal-fired steam electric generating units. The power station is cooled by water that is taken in from Tampa Bay through two intake structures which are located along TEC's intake canal. One intake structure feeds cooling water to electrical power units 1 and 2 and the other feeds units 3 and 4. After flowing through the condensers, the cooling flows are combined into four separate discharge tunnels which outfall into TEC's discharge canal. The intake structure for Units 3 and 4 is equipped with fine-mesh screens and an organismal collection and return system that has been approved for use by DEP. The purpose of TEC's permit modification is to alter the internal piping in the facility to accommodate the desalination plant at the Big Bend site. TEC's permit modification allows for placement of an intake pipe from TEC's cooling water pipes to the desalination plant and a return pipe downstream from the intake pipe for the return of the desalination concentrate to TEC's cooling water discharge tunnels prior to outfall in the discharge canal. TEC's permit modification also allows for the placement of an auxiliary intake line by TBD to take additional water from behind the intake of units 3 and 4 up to TEC's maximum permitted limit of 1.4 billion gallons a day. The TEC proposed permit is conditioned to require TEC to maintain the structural integrity of both the steel sheet pile wall on the discharge canal and the breakwater barrier North of the discharge canal. TEC's permit modification does not request any changes to the operations of the Big Bend Generating Station. SOBAC Issues and Concerns SOBAC raised numerous issues and concerns in its petitions in these cases and in the Pre-Hearing Stipulation. However, some issues were elimination by rulings adverse to SOBAC during prehearing proceedings and final hearing. Based on the evidence SOBAC sought to elicit at final hearing and issues raised in its Proposed Recommended Order, other, earlier SOBAC issues and concerns appear to have been dropped. Remaining are essentially the following: increased salinity due to TBD discharge; alleged decreased dissolved oxygen (DO) from higher salinity; impacts of higher salinity and alleged decreased DO on marine plants and animals; alleged release of metals from sediments due to higher salinity and alleged lower DO, and effects on marine plants and animals; alleged monitoring deficiencies; alleged failure to utilize available technologies to lower salinity and raise DO; alleged deficient financial assurances; and various alleged resulting DEP rule violations. Description of Tampa Bay: Physical Properties The portion of Tampa Bay and Hillsborough Bay near the Big Bend facility is classified a Class III water body. Tampa Bay is a naturally drowned river valley, meaning that a deep channel exists as a result of natural forces. However, the channel has been deepened to 45 feet or greater to allow large ships to navigate the bay. This deepening of the channel increases the water flow of the head of the bay with the open gulf waters and allows this residual circulation to move more new water from the open Gulf of Mexico up into the bay. Ordinarily, circulation moves salt water up Tampa Bay and spreads it out onto the flanks of the bay where it then mixes with the freshwater. To complete this circulation, the water then flows back out towards the mouth of the bay, primarily along its flanks and shallower parts in the upper part of the water column. The water in Tampa Bay tends to flow faster in its deeper parts, both coming in and going out, and relatively slower in the shallow areas. The majority of flow of freshwater inflow occurs at the bay's flanks as can be seen very clearly in the salinity distributions. Mixing and Stratification Since the development of Tampa Bay from the 1880 condition to the 1972 and 1985 conditions, there is more mixing and exchange of water. Due to shoreline fills for development, such as Apollo Beach, there is less water that now comes in the bay than in the predevelopment condition. Tampa Bay is a fairly well mixed system from top to bottom. This is because the action of the tides basically acts like a big mix master. The bay is fairly shallow, less than four meters in depth on average. The tidal velocities can be as strong as two knots or about a meter per second. When the strong velocity pushes through shallow water, there is extensive overturning, where the bottom water is churned to the top and gets mixed very efficiently. That is very well seen in the observations during dry periods. Over 100 points in Tampa Bay were measured for temperature and salinity top, middle and bottom, and showed that they were very uniform throughout the bay. During periods of large volumes of freshwater input into Tampa Bay, freshwater is pumping into the bay faster than the tidal mixing can mix it from top to bottom. Therefore, in parts of Tampa Bay significant stratification is seen during many times in the wet season. During those times when rainfall is not as prevalent, tidal mixing once again dominates and the bay returns to a more well mixed system. The average tidal fluctuation for Tampa Bay is a range of two to three feet. Salinity As the tide in Tampa Bay comes in, it brings saltier water from the mouth of the bay toward the head of the bay, causing salinities to rise. As the tide recedes, bringing out fresher water from farther up the bay, salinities decrease. Over an individual tidal cycle, particularly during the wet season, a four or five part per thousand ("ppt") change in salinity will occur between a rising tide and a falling tide. During the dry season, tidal flushing is not as significant to salinity levels because not much difference exists in salinity from the head of the bay to the mouth of the bay. Even during the dry season, there is a one to two ppt change over a six to twelve-hour period in any given day. During the dry periods in 1990, salinities elevated up to about 33 ppt, with very little stratification. During the rainy periods, in June and July, salinities dropped rather drastically. In some areas, salinity dropped as low as to 20 to 22 ppt. However, in spite of these drastic seasonal differences, significant variation in salinity occurs as a result of tidal exchange. The Big Bend area is split by the dividing line between Hillsborough Bay and what has been classified Middle Tampa Bay. The salinity for Hillsborough Bay from 1974 through June 2001 at the surface ranges from 0.4 ppt to 38.2 ppt. The middle portion of the same water column contained a range from 2.5 ppt to 39.2 ppt, and the bottom portion showed a range from 3.9 ppt to 37.2 ppt. The average salinities during this time frame were as follows: top 24.2 ppt, middle 24.3 ppt and bottom 25.3 ppt. In the portion of Tampa Bay called Middle Tampa Bay, the surface level salinity ranged from 6.8 ppt to 38.2 ppt. At middle depth, salinities ranged from 7.4 ppt to 38.8 ppt. The bottom level salinities ranged from 11.9 ppt to 39.6 ppt. This is a large range of salinities. Tampa Bay near the Big Bend Area In the area near the Big Bend facility, the Mote Marine Laboratory survey data reflects that the salinity during May and June 2000 reached 33.4 ppt. Further, Mote Marine Laboratory data showed that the North Apollo Embayment area salinities were well mixed vertically throughout the system. The total volume of water exchanged into the North Apollo Embayment and associated canals during a mean tide is approximately 35 percent of the total volume of all water contained in that area. This tidal exchange occurs twice per day. The double diffusion process does not create high salinity in the bottom of the water column in the North Apollo Embayment. The double diffusion process, without any external influence, would lead to both surface and bottom layers of the water column reaching salinity equilibrium. Further, the turbulent mixing that occurs due to tidal processes and wind- induced mixing dominates over the double diffusion process. The Mote Marine Laboratory study conducted between May and early June 2000 did not detect any significant salinity stratification in the area near the Big Bend facility. Vertical stratification of salinity does occur but typically only during the periods of significant freshwater inflow and not in extreme drought or dry conditions. None of the Mote Marine Laboratory data detected any pockets of high salinity water or significant density stratification in the North Apollo Embayment. Estuarine Characteristics Tampa Bay is an estuary. Estuaries are semi-enclosed bodies of saltwater that receive freshwater runoff from drainage or riverine inflow, which measurably dilutes the salinity levels in the estuary. As a result, salinity levels in estuaries typically are highly variable, ranging from 0 ppt where rivers flow into estuaries, to as high as 40 ppt under conditions of low freshwater input or at estuarine mouths where they connect to the sea. There are naturally occurring dissolved oxygen levels below 4.0 mg/l in parts of Tampa Bay, including at Hillsborough County Environmental Protection Commission ("EPC") monitoring stations 9, 80, and 81, which are the closest stations to the proposed discharge. Dissolved oxygen in the bay decreases at night because photosynthesis ceases and respiration exceeds production. Other environmental parameters are also highly variable in estuaries. Therefore, the organisms that inhabit estuaries have adapted to tolerate these highly variable conditions. Estuarine organisms have adaptive means for tolerating changing salinity levels, either by conforming their internal salinity levels to the ambient salinity levels, or by actively regulating their internal salinity levels by intake or excretion of salt. Organisms that are adapted to tolerate a wide range of salinities within the estuary are termed euryhaline organisms. Essentially all of the common organisms in estuaries, including the Tampa Bay estuary, are euryhaline organisms, and therefore are capable of tolerating and living in a wide range of salinities and salinity changes that occur due to tidal, meteorological, and other natural forces in the estuarine environment. Extensive baseline biological studies performed on Tampa Bay reveal that the most common species in the Tampa Bay estuary tolerate salinity levels ranging from 5 ppt to 40 ppt. Seagrasses Five species of seagrass inhabit Tampa Bay. Seagrasses are photosynthetic underwater flowering plants that are typically limited in occurrence and distribution by the water clarity. This limits the depth at which seagrasses can grow. In Tampa Bay, seagrasses are limited to the fringes of the Bay, and are largely limited to depths of approximately three feet, although they can live in depths of up to six feet in clearer parts of the Bay. Seagrasses are very sensitive to increases in nutrients, like nitrogen and phosphorus. These nutrients encourage algae growth, resulting in competitive stress in seagrasses. Due to poor water quality caused by sewage discharge, dredging and filling, and other activities in the Bay, seagrass distribution in Tampa Bay decreased from an historic coverage of approximately 80,000 acres in 1950 to approximately 20,000 acres by 1982. Improvements in water quality, largely due to sewage treatment improvements, have allowed seagrasses to naturally recolonize to approximately 27,000 acres coverage, as of 1994. Wave energy affects seagrass distribution. Seagrasses cannot colonize and survive in areas subject to significant wave energy. For example, the portion of Tampa Bay dredged and filled to create the Apollo Beach "hammerhead" area was once comprised of a broad shallow-water shelf that diminished wave energy, allowing dense seagrass flats to cover the shelf area. Destruction of the broad shallow-water shelf with fill to create the Apollo Beach hammerhead has converted the area to a high wave energy system that is unsuitable for seagrass colonization and growth. Consequently, the only seagrasses inhabiting the Big Bend area are found approximately one kilometer north of the Big Bend power plant, in an area known as "The Kitchen," and approximately one kilometer south of the Apollo Beach hammerhead area. Additionally, there are ephemeral patches of seagrass inhabiting some limited areas of the North Apollo Embayment. Seagrasses are adapted to tolerate a wide range of salinities. They have specialized cells that enable them to deal with salt stress and with broad ranges of and fluctuations in salinity. These adaptations enable them to survive and thrive in estuarine environments. Of the seagrass species that live in Tampa Bay, one species, Ruppia maritima (widgeon grass), occurs in salinity ranges from zero to 40 ppt. Manatee grass, Syringodium filiforme, is most productive in salinities between 5 ppt and 45 ppt. The other three species, Halodule wrightii (shoal grass), Halophila engelmannii (star grass), and Thalassia testudinum (turtle grass), tolerate salinity ranges from approximately 5 ppt to 60 ppt. Seagrasses better tolerate higher salinity levels than lower salinity levels. Lower salinity levels are usually indicative of increased stream and land freshwater runoff, which usually is accompanied by increased turbidity and lower water clarity. Four of the five seagrass species that inhabit Tampa Bay typically reproduce asexually by producing rhizomes, rather than by flowering and producing seeds. It is not completely clear why seagrasses in Tampa Bay reproduce asexually rather than by flowering and seed production. However, recent research indicates that climatic temperature is the controlling factor for flower and seed production. In South Florida, where the climate is warmer, seagrasses reproduce by flowering and seed production. In Tampa Bay, the lower winter temperatures appear to be the limiting factor with respect to successful flower and seed production in seagrasses. Recent studies by the University of South Florida ("USF") marine laboratory indicate that naturally occurring fungal diseases may also limit successful flowering and seed production in seagrasses in Tampa Bay. Since most seagrass species that live in Tampa Bay tolerate and thrive in salinities of up to 60 ppt, the higher salinity levels in the estuary do not appear to adversely affect the ability of seagrasses to reproduce. In fact, the lower salinity levels, below 5 ppt, stress seagrasses and are more likely to adversely affect reproduction than do higher salinity levels. Mangroves Three major species of mangrove inhabit the Tampa Bay area: the red mangrove, black mangrove, and white mangrove. Mangroves inhabit the intertidal area, so they are subjected to daily tidal flooding and drying. Consequently, they must tolerate a wide range of variability in salinity levels and in water availability. Most mangroves tolerate soil salinity levels up to 60 ppt, close to twice the salinity of Tampa Bay. Mangrove mortality due to salinity does not occur until soil levels approach and exceed 70 ppt salinity. Mangroves are also adaptable to, and inhabit, freshwater environments. Phytoplankton and Zooplankton Plankton are life stages or forms of larger organisms, or organisms that have no ability for major locomotion, so they spend their entire life spans floating and drifting with the currents. Plankton are extremely productive in that they reproduce in very large numbers within very short life spans. Holoplankton are planktonic organisms that spend their entire lives in planktonic form. Examples include diatoms, which are a type of phytoplankton, and copepods, which are a type of zooplankton. Meroplankton are "temporary" plankton that drift with the currents in juvenile or larval stages, then either settle out of the water column and metamorphose into an attached form (such as barnacles) or metamorphose into mobile life forms (such as crabs, shrimp, and fish species). Phytoplankton are planktonic plant species and life forms. Zooplankton are planktonic animal species and life forms. Zooplankton feed on phytoplankton. There are approximately 300 species of phytoplankton, and numerous species and forms of zooplankton, found in Tampa Bay. Most phytoplanktonic and zooplanktonic species inhabiting Tampa Bay are euryhaline species capable of tolerating the wide range of salinity levels and abrupt salinity changes that occur naturally in the estuarine system. Most phytoplanktonic and zooplanktonic species and life forms in Tampa Bay tolerate salinity levels ranging from zero to 40 ppt. They appear to be more tolerant of the higher end than the lower end of this salinity range. Manatee The manatee is the only endangered or threatened species identified by the Florida Natural Areas Inventory as inhabiting the area where the desalination plant is proposed to be located. Manatees congregate at the Big Bend Power Station during colder months because they are attracted to the power plant's warmer water discharge. Manatees are considered to be estuarine species, but they have very broad salinity tolerance ranges. They migrate into and out of freshwater springs, through estuaries, into the Gulf of Mexico, and down to the Ten Thousand Islands, where hypersaline conditions frequently exist. Manatees routinely expose themselves to and tolerate salinities ranging from zero to more than 40 ppt. Fish The fish populations in Tampa Bay are comprised of a large number of marine euryhaline species. Due to their ability to osmoregulate their internal salinity levels, these fish species can inhabit salinity ranges from 5 ppt to as high as 40 ppt. Extremely extensive monitoring and sampling programs are currently being conducted in Tampa Bay and specifically in the vicinity of the Big Bend Power Station. The Hillsborough County EPC, SWFWMD, TBW, the United States Geological Survey ("USGS"), the Florida Marine Research Institute, USF, and Mote Marine Laboratory conduct separate biological monitoring programs that sample and monitor numerous biological parameters, including invertebrate infaunal and epifaunal species composition, abundance, and distribution; zooplankton and phytoplankton species composition, abundance, and distribution; emergent and submerged vegetation species composition, abundance, and distribution; and fish species composition, abundance, and distribution. These monitoring programs, which collect and analyze biological data from many areas in the Tampa Bay estuarine system, extensively monitor numerous biological parameters in the Big Bend area. Testing and Modeling Pilot Plant Although DEP's rules do not require the use of a pilot plant to demonstrate reasonable assurances, TBD installed a desalination pilot plant at the Big Bend site in November 1999. The pilot plant matched the hydraulics and configuration of the full-scale facility on a 1/1000 scale. The pilot plant used water from the Big Bend power plant discharge as its source water. The purpose of the pilot plant was to confirm design requirements for the desalination facility and to provide samples of intake water, filtered water, pretreated water, concentrate, and finished water to use for chemical characterization and analysis. Using a pilot plant is superior to using data from engineering projections or data from a different desalination facility because the pilot plant provides data specific to the Big Bend site. Data from the pilot plant were used to establish various effluent and other limits in the permit. Chemical Characterization Intake water, filtered water, pretreated water, concentrate, and finished water from the pilot plant were analyzed for over 350 parameters chosen by DEP to determine chemical characterizations and water quality. The pilot plant operation provides extensive chemical characterization of intake and discharge water composition and mass loading. This information was key in providing accurate information on the chemical composition and mass loading of the desalination discharge concentrate. With this accurate information on the components in the discharge water, DEP was provided more than sufficient reasonable assurance on the potential effect of the chemical components of the discharge. TBD tested the pilot plant discharge water for copper, nickel, other heavy metals, and those chemical constituents specified on the DEP chemical characterization form. The chemical characterization tested for concentrations of constituents based on a 12.8 to 1 dilution ratio, and even at that dilution ratio, did not exceed any of the state water quality parameters. However, to provide additional assurance that there will not be an exceedance of state water quality standards, the permit requires a minimum 20 to 1 dilution ratio. Dissolved Oxygen Saturation Testing Temperature and salinity affect the saturation point of dissolved oxygen ("DO") which is lowest when temperature and salinity are highest. DO saturation charts, which are typically used to determine DO saturation points, are not applicable because those charts do not contain the saturation point of DO at a temperature of 109 degrees Fahrenheit and a salinity of 79 ppt, which represents the worst case conditions for the proposed desalination facility. Bench-scale testing was performed on the undiluted desalination discharge from the pilot plant by heating discharge concentrate samples to 109 degrees Fahrenheit and aerating the samples until the DO stabilized and reached saturation point. The pilot plant bench-scale testing determined that the saturation point of DO in the worst case desalination concentrate using a temperature of 109 degrees Fahrenheit and salinity of 79 ppt was 5.7 mg/l. Toxicity Testing TBD conducted acute toxicity testing using a worst case scenario assuming a diluted effluent of one part desalination concentrate to 12.8 parts of power plant cooling water. Acute toxicity testing evidenced no mortalities, showing that the proposed discharge will not be a source of acute toxicity. TBD conducted chronic toxicity testing on raw concentrate from the pilot plant using a worst case scenario diluted effluent of one part desalination concentrate to 12.8 parts of power plant cooling water. The No Observed Effect Concentration (NOEC) for raw concentrate was determined to be 100 percent and the NOEC for diluted effluent was determined to be greater than 100 percent. The evidence did not explain these concepts, but it was clear from the tests that the proposed discharge will not be a source of chronic toxicity. TBD conducted its acute and chronic toxicity testing using protocols reviewed and approved by DEP. TBD's toxicity testing was also consistent with accepted EPA standards. Assessment of Potential Environmental Impacts TBD prepared an Assessment of Potential Environmental Impacts and Appendices ("Assessment") to analyze the potential biological impacts of the desalination plant discharge into the Tampa Bay estuary. The Assessment examined numerous physical parameters to determine the baseline environmental conditions in the portion of Tampa Bay proximate to the proposed desalination plant site. Among the physical parameters examined in determining the baseline environmental conditions were: salinity; sediment size and composition; metal content in sediments; and numerous water quality parameters such as transparency, biochemical oxygen demand, pesticides, dissolved metals, and pH. Consistency with SWIM Plan As part of the permitting process, TBD was required to demonstrate consistency of the proposed desalination discharge with the SWFWMD's Surface Water Improvement and Management (SWIM) plan, pursuant to Rule 62-4.242. TBD submitted an extensive SWIM consistency analysis, which is sufficient to meet the consistency requirement. Water Quality Based Effluent Limitation Level II Study TBD performed a Water Quality Based Effluent Limitation (WQBEL) Level II study pursuant to Rule Chapter 62- 650 for the purpose of determining the effect of the desalination plant discharge on salinity levels in the vicinity of the desalination plant discharge. TBD had the Danish Hydrologic Institute ("DHI") use the data collected through the WQBEL Level II study in its near-field model of the Big Bend area. See Findings 105-117, infra. DEP also used the data and the DHI model results to establish the salinity and chloride effluent limitations in the permit. The USF Far-Field Model The far-field model was prepared utilizing the Princeton model code. The Princeton model is well recognized and is generally accepted in the scientific community. The goals of the TBD far-field model performed through USF by Dr. Luther and his team were to evaluate the change in bay-wide salinity due to the desalination plant discharge, both alone and in combination with changes in salinity due to enhanced surface water system withdrawals under new consumptive water use permits issued to TBW by SWFWMD to provide other, additional sources of needed potable water supply. The primary goal was to provide DEP with the best science possible of the potential real effects of this desalination discharge into Tampa Bay. The modeling system of Tampa Bay utilized in this analysis was developed beginning in 1989. Dr. Luther and his team have continued to make refinements to the model over the last 12 years. Dr. Luther took the modeling system he had developed over the years for Tampa Bay and did three primary model scenarios. The baseline case reproduced the observed conditions during the 1990 and 1991 years--a very dry period in 1990 and a fairly wet period for 1991--as accurately as possible with all the boundary conditions estimated from observations. This was to capture an entire range of conditions in Tampa Bay. The baseline was then compared with validation data and other observations to ensure it was approximating reality. The second simulated scenario included the same effects as the baseline with the added effect of the desalination intake and discharge at the Big Bend facility. The third case approximated cumulative effects from the TBW enhanced surface water system river withdrawals according to the proposed permit withdrawal schedules. For each test case, it was assumed that only two of the four cooling units at the TEC Big Bend plant were in operation for an entire two-year period, a worst-case scenario expected to occur less than four percent of the time in any given year. The model included data on water levels, temperature, and salinity throughout Tampa Bay. In addition, it takes into account wind blowing across the surface of Tampa Bay, rainfall, freshwater inflow from rivers, and other surface water and groundwater sources. The model was calibrated and validated against actual data to verify simulation of reality as closely as possible. The model was calibrated and validated utilizing Hillsborough County EPC and Tampa Oceanographic Project ("TOP") salinity data. Physical Oceanographic Real Time System ("PORTS") and TOP data on current flow velocity and water levels were utilized to calibrate and validate water levels and current. The acoustic doppler current profilers used in the model study are able to measure the speed at which the water is traveling and the direction at various levels above the bottom within the water column. The TBD far-field model very accurately reproduces the observed tidal residual velocities observed with the acoustic doppler current profilers. The far-field model reflects any stratification that would occur during the model simulations. The far-field model simulates recirculation that occurs between the discharge and intake water. Recirculation is small due to the model's use of the actual bathymetry of Tampa Bay. There are significant shoals and other features that separate the water from the discharge and the intake canal that preclude significant recirculation most of the time. After submitting the far-field model report to DEP, further study was performed on the far-field model that calculated residence time for Tampa Bay. One study dealt with "residence" or "flushing" time. The concept of "residence time" is not well-defined; put another way, there are many different accepted ways of defining it. It may be defined in a simplified manner as the time it takes a patch of dye to flush out of the bay. However, for purposes of the studies performed on the far-field model, theoretical "particles" in model grids were tracked, and "residence time" was defined as the time it would take for the number of particles initially in a grid cell to decrease to 34 percent of the initial number. Using this approach and definition, residence time in the vicinity of the Big Bend facility on the south side where the discharge canal is located was less than 30 days. Immediately offshore of the area of the discharge, the residence time reduced to less than 15 days. The study indicated that the area of the Big Bend facility has a relatively low residence time. In the model's baseline run (for the desalination plant impacts only), maximum differences in salinity occurred during the month of April 1991. Throughout the two-year time period, the maximum concentration of salinities did not increase from this point, and in fact decreased. The maximum average value for salinity difference is 1.3 ppt at the grid cell located directly at the mouth of the TEC Big Bend discharge canal. More than two grid boxes away in any direction and the value falls to less than 0.5 ppt increase in salinity. The maximum salinity of any given day for the far- field model was in the range of 2.1 to 2.2 ppt, which compares favorably with the DHI near-field model which showed an increase of 2.5 ppt. The salinity changes caused by the cumulative effects scenario are smaller than the natural variability during the wetter months in Hillsborough Bay in cells immediately adjacent to the concentrate discharge. Increases in salinity will occur in the vicinity of the discharge canal but will be very localized and small relative to the natural variability in salinity observed in Tampa Bay. At a distance of more than a few hundred meters from the mouth of the discharge canal, it would be difficult (if not impossible) to determine statistically that there would be any increase in salinity from the desalination concentrate discharge. Over the two years modeled, there is no trend of increasing salinity. No long-term accumulation of salt is evidenced within the model. Further, no physical mechanism exists within the real world that would allow for such a long- term accumulation of salinity in Tampa Bay. Dr. Blumberg's independent work verified the conclusions in the far-field model constructed by USF. Dr. Blumberg's estimated flushing times are consistent with those found in the far-field model. DHI Near-Field Model The TBD near-field model was prepared by DHI. DHI prepared a three-dimensional near-field model to describe the potential salinity impacts from the discharge of the proposed desalination plant. The DHI model is a state-of-the-art model whose physics are well documented. By model standards, the DHI near-field model is a high resolution model. The DHI model essentially "nests" within TBD's far-field model. The near-field area includes those areas that would be directly influenced by the combined power and desalination discharges, the North Apollo Embayment and the residential canal system adjacent to the discharge canal. The near-field model was designed to determine whether or not the desalination plant would cause continuous increases in salinity and to predict any increase in salinity in the North Apollo Embayment and the associated canal system. In addition, DHI evaluated the potential for saline recirculation between the discharge and the intake via short circuiting due to overtopping of the existing break water. In order to construct the near-field model, existing data on bathymetry, wind sources, meteorology and other parameters were examined and analyzed. In addition, the information from an intensive data collection effort by Mote Marine Laboratories on current velocities, temperatures, and salinities was incorporated into the model. TBD conducted bathymetric surveys in the residential canal areas, the North Apollo Embayment, and the area between the discharge canal and the intake canal. The model has a vertical structure of six grids and reflects vertical stratification that would occur in the system being modeled. The vertical grids in the model can detect a thermal plume one meter in depth (the size of the thermal plume from TEC's discharge). Information about the TEC thermal plume was incorporated into the model and utilized to calibrate the model's predictive capabilities. The model took into account interactions between the temperature plume and the salinity plume. The model predictions matched the measured temperature plume created by the TEC discharges quite well. The near-field model conservatively assumed a scenario in which only the two TEC units with the smallest total through-flow of 691.2 million gallons a day cooling water were active. DHI then assumed production of a maximum 29 mgd in product water. A salinity level of 32.3 ppt at the intake was utilized in the simulation. The model assumed a conservative wind condition which results in less mixing and dispersion of the plume. Further, wind direction tended to be from the southwest or west during the simulation, which tends to push the plume against the TEC break water which tends to reinforce recirculation. SOBAC witness Dr. Parsons agreed that these simulations for April and May 2000 constituted extreme conditions. DHI ran its model for a total time period of six weeks. The "warm up" for the simulation took place from April 15 to May 7, followed by the "calibration" simulation from May 8 to May 22. An additional validation sequence was run from May 25 to June 8. The production run was defined as the three weeks from May 8 to May 29, 2000. The intensity of the calculations performed in the near-field model due to its high spacial resolution and numeric restrictions make it computationally demanding. The calibration runs took approximately a week to 10 days to run on a state-of-the-art computer. From a computational standpoint, it is not practical to run the near-field model for a two-year time period. The model shows good agreement between its water levels and current velocity to observed data. The model reflects the recirculation of the discharge water that would occur in the system. The maximum salinity for the extreme case scenario in the near-field model is an increase in salinity of 2.5 ppt. With three condensers running, under the modeling scenario comparing the base condition to the desal discharge, there is a maximum difference of only 2.0 ppt. Further, there is no indication of any continuous build up of salinity in the near- field area due to the desalination plant discharge. DHI performed many sensitivity runs on the model, including one which examined rainfall conditions. The results of a two-inch rainfall analysis show that rainfall profoundly freshens the water in the near-field area. Since the modeling was done in a time period of extreme drought, with no freshwater inputs, the ambient or background salinity trended up over the time frame of May through June. As with any estuary, if freshwater inflow is removed, the estuary will get saltier until freshening occurs. Even with the model simulation period extended an additional 10 days beyond that reflected in TBD Ex. 1-O, the model results did not show any increase of salinity differences caused by the desal facility above 2.5 ppt. Based on data from field collections, the operation of the desal plant under worst case conditions did not exceed the assimilative capacity of the near-field environment. A 10 percent salinity change (3.23 ppt) was not reached in any grid cell. The Blumberg Study The "Environmental Impact Assessment for a Seawater Desalination Facility Proposed for Co-Location with the Tampa Electric Company Big Bend Power Generation Facility Located on Tampa Bay, Florida" authored by Norman Blake and Alan F. Blumberg ("Blumberg Study") is a hydrodynamic model study combined with an analysis of potential biological effects. The Blumberg Study was performed at the request of and presented to the Board of County Commissioners of Hillsborough County, Florida. Dr. Blumberg's model used 1998 and 1999 as its baseline, which consisted of an extremely wet year followed by an extremely dry year. The model assumed a scenario of two cooling units in operation pumping 656 mgd of discharge flow. The results of the Blumberg Study are very similar to the results of TBD's far-field model. In addition, the model ran for a 9-year period without any sign of ongoing build-up of salinity. After the two-year model run, the second year ran for an additional 7 simulated years for total model simulation period of 9 years. The Blumberg Study found salinity only increased by 1.4 ppt in the North Apollo Beach Embayment. In fact, the Blumberg Study showed no salinity build-up after the second year of the 7-year portion of the model simulation. The Blumberg Study found that the flushing time for the area near the Big Bend facility ranges from 4 to 10 days. The Blumberg Study applied a formula to predict potential DO saturation level changes. The analysis concluded a small change to DO saturation assuming full saturation on average of 7 mg/l. The Blumberg Study predicted that the desalination discharge would not lower actual DO levels below 5 mg/l. The Blumberg Study concluded that the marine ecology will not be affected by the desalination facility operation. Older Two-Dimensional Models of Tampa Bay Significant strides have been made in hydrodynamic modeling over the last 10 years, with the standard changing from two-dimensional models to three-dimensional models. Three-dimensional models provide more complete results than two-dimensional models. In the late 1970's through the late 1980's, modeling was constrained by the computing limitations of the time and could not examine the difference in water layers in a bay and potentials for currents going in different directions or speeds in different layers of the bay, as now done by state-of-the-art three-dimensional models. A two-dimensional model cannot accurately represent the tidal residual circulation in an estuary such as Tampa Bay, because it omits some of the critical physical forces that drive this type of flow. As the acoustic doppler current profiler showed, water flows in the top of the water column in one direction and flows in the bottom of the water column in a different direction. A two-dimensional model would average these flows over the entire vertical water column. In doing so, it would show much slower residual flow (and, therefore, longer residence time and a longer time to flush the system). SOBAC offered the testimony of Dr. Carl Goodwin, a civil engineer with the USGS. Dr. Goodwin provided testimony on two-dimensional model studies he did for the USGS in the late 1980's to assess the effects of dredging the shipping channel in Tampa Bay. Dr. Goodwin's studies, contained in SOBAC Exs. 69 and 70, suggested the existence of "gyres" in Tampa Bay. But no "gyres" have been observed, and it now appears that these gyres actually do not exist but are two- dimensional modeling artifacts, as shown by state-of-the-art three-dimensional modeling of Tampa Bay. In an earlier version of Dr. Luther's Tampa Bay model, an experiment was performed running the model in a vertically average mode to mimic the two-dimensional model. In this mode, the model was able to reproduce the "gyres" that Dr. Goodwin observed in his two- dimensional model. When the physical equations that related to pressure forces (baroclines) were reactivated in the three- dimensional model, the "gyres" disappeared. In addition, this experiment showed that the two- dimensional model simulation showed residence times an order of magnitude longer as compared to the full three-dimensional simulation. This means that residence time would be 10 times longer in the two-dimensional model than in the three- dimensional model, which takes into account baroclinic forces. Subsequent to the publication of his modeling studies (SOBAC Exs. 69 and 70), Dr. Goodwin found that it would take approximately 110 days for water to travel from the mouth of the Hillsborough Bay to the mouth of Tampa Bay in 1985. This calculation by Dr. Goodwin was not subjected to peer review or the USGS process. However, dividing the 110-day time period with correction factor of 10 discussed above, Dr. Goodwin's corrected estimate would predict an 11-day period for transport of water from Hillsborough Bay to the mouth of Tampa Bay--similar to the Blumberg Study and far-field model results. Opinions of Other SOBAC Experts Besides Dr. Goodwin, SOBAC also elicited some general opinions regarding the combined thermal and salinity plume from Dr. Mike Champ, called as an expert in the areas of environmental biology and chemistry, and from Dr. Wayne Isphording, called as an expert in sedimentology and geochemistry. In part, Dr. Champ based his opinion on a misunderstanding that Tampa Bay is not well-mixed or well- circulated at the location of the Big Bend power plant. In this respect, Dr. Champ's testimony was contrary to all the evidence. Even the "gyres" suggested by Dr. Goodwin's two- dimensional model studies would suggest a great deal of mixing in Middle Tampa Bay in the vicinity of the Big Bend plant. To the extent that the opinions of Dr. Champ and Dr. Isphording differed from the modeling results, they are rejected as being far less persuasive than the expert opinions of the modelers called by TBD, who spent far more time and effort studying the issue. Compliance with Dissolved Oxygen Standard Oxygen is a gas which can dissolve in water to some degree. There are two measurements of DO in water: saturation point and actual level. The saturation point of DO in water equates to the maximum amount of DO that water will hold. The actual level of DO is a measurement of the oxygen in the water. Since the saturation point is the maximum amount of DO that water will hold in equilibrium, the actual level of DO in water is typically equal to or lower than the saturation point. Desalination will affect the saturation point of DO to the extent that it increases salinity. Increased salinity decreases the saturation point of DO because it lowers the potential for water to hold oxygen. But desalination would not affect the actual level of DO in the water if the saturation point remains above the actual level of DO in the water. TBD determined that in the worst case scenario using undiluted desalination discharge, the lowest possible saturation point of DO would be 5.7 mg/l. If the actual level of DO is above 5.7 mg/l, desalination may lower that actual level of DO to 5.7 mg/l. If the actual level of DO is below 5.7 mg/l, desalination will not lower the DO. Since TBD will aerate the water in the pretreatment process, if the actual level of DO is below 5.7 mg/l, the actual level of DO in the discharge water will be increased. The permit DEP proposes to issue to TBD requires that DO at the point of discharge from the RO plant meet the following: that instantaneous DO readings not depress the intake DO when intake DO is at or below 4.0 mg/l, and that they be greater than or equal to 4.0 mg/l when intake DO is greater than 4.0 mg/l; that 24-hour average readings not depress the 24-hour average intake DO when the 24-hour average intake DO is at or below 5.0 mg/l, and that they be greater than or equal to 5.0 mg/l when the 24-hour average intake DO is greater than 5.0 mg/l. The evidentiary basis for SOBAC's argument that the proposed permit's DO limitation allowed violations of state water quality standards was the testimony of Dr. Champ. But it was evident from his testimony that Dr. Champ was not even aware of the effluent limitations until they were pointed out to him at final hearing. Nonetheless, and although Dr. Champ barely had time to read the DO limitations, Dr. Champ immediately opined that the proposed DO limitations virtually invited water quality violations. He dismissed the permit language out-of-hand as being "loosey-goosey," "fuzzy-wuzzy," and "weasel-like." Actually, there is no conflict between the proposed permit's DO limitations and the water quality standards and water quality criteria in DEP's rules. Other witnesses, particularly Tim Parker of DEP, properly compared the language in the permit with DEP's rules containing water quality standards and water quality criteria. Mr. Parker pointed out that the rules must be read in harmony with each other. Rule 62-302.530(31) contains DO water quality criteria and requires that the "actual DO shall not average less than 5.0 in a 24 hour period and shall never be less than 4.0." Rule 62-302.300(15), a water quality standard, states: Pollution which causes or contributes to new violations of water quality standards or to continuation of existing violations is harmful to the waters of this State and shall not be allowed. Waters having a water quality below the criteria established for them shall be protected and enhanced. However, the Department shall not strive to abate natural conditions. Mr. Parker testified that the "natural conditions" referred to in Rule 62-302.300(15) are those found in the intake water to the desalination facility. TBD will not violate either the water quality criteria or the water quality standard for DO. If the actual level of DO in the intake water is less than 5.0 mg/l, TBD will not decrease the actual level of DO in the water below 5.0 mg/l because the actual level of DO is below the worst case saturation point of 5.7 mg/l. The water quality standard in Rule 62-302.300(15) does not prohibit discharges having DO levels below 4.0 mg/l when that discharge does not cause or contribute to existing DO violations. TBD will not cause or contribute to existing DO violations because if the level of DO in the intake water which is the natural condition is less than 4.0 mg/l, TBD will not decrease the actual level of DO in the water. To the contrary, the desalination process will increase the actual level of DO whenever it is below 5.0 mg/l. TBD has provided reasonable assurance that the proposed desalination discharge will not violate the DO water quality standards and criteria in Rules 62-302.530(31) and 62- 302.300(15) because the desalination process will not decrease the actual level of DO below 5.0 mg/l. SOBAC argued that DO levels will drop between intake and discharge as a result of desalination. Some of this argument was based on the testimony of Dr. Mike Champ, one of SOBAC's expert witnesses. But Dr. Champ's testimony on this point (and several others) is rejected as being far less persuasive than the testimony of the expert witnesses for TBD and the other parties. See Finding 196, infra. SOBAC's argument apparently also was based on a fundamental misapprehension of the results of the Blumberg Study, which SOBAC cited as additional support for its argument that desalination will decrease DO at the discharge point. The Blumberg Study only spoke to desalination's effect on DO saturation concentrations, not to its effect on actual DO levels. (In addition, contrary to SOBAC's assertions, the Blumberg Study did not model DO saturation concentrations but only inferred them.) pH The pilot plant measured and analyzed the potential for pH changes in the desalination process and demonstrated that the desalination process reduced pH by no more than a tenth of a pH unit. pH ranges in natural seawater from top to bottom change over one full pH unit; a tenth of a pH unit change would be well within the natural variation of the system. TBD has provided reasonable assurances that the proposed desalination discharge will not violate Rule 62- 302.530(52)(c), which requires that pH shall not vary more than one unit above or below natural background of coastal waters, provided that the pH is not lowered to less than 6.5 units or raised above 8.5 units. Limitations for pH in the permit ensure compliance with Rule 62-302.530(52)(c) at the point of discharge to waters of the state. Temperature Nothing in the desalination process adds heat to the discharged water. To the contrary, the desalination process may dissipate heat due to the interface of the intake water with the air surface in the pretreatment process. Further, the effect of removing 25 mgd of heated cooling water as desal product water reduces the heat load coming out of the TEC plant cooling water discharge by that same 25 mgd. Temperature readings taken as part of the pilot plant study confirm a slight decrease in temperature across the desalination process. Metals The pretreatment process employed by TBD will result in a reduction in metals in the treated water. Ferric sulfate is added to the intake water upstream of the sand filters in the pretreatment process to precipitate metals into solid material which can be captured by the sand filters. Adding ferric sulfate in the pretreatment process results in a net reduction in the total mass load of metals in the discharge water. Initial calculations in the permit application that 104 pounds of ferric sulfate were being discharged in the desalination concentrate were based on using 20 mg/l of ferric sulfate and a conservative estimate of 95 percent settling of solids, with 5 percent of the ferric sulfate being discharged in the desalination concentrate. Further testing through the pilot plant revealed that coagulation optimizes at 9 to 14 mg/l of ferric sulfate with 97.5 percent of the solids settling, resulting in only 2.5 percent (52 pounds) of the ferric sulfate being discharged per day. The desal facility discharge of iron is minute in comparison to naturally occurring metals within the surface water flowing into Tampa Bay from the Hillsborough and Alafia Rivers. Increases in iron due to ferric sulfate addition are predicted to result in a diluted discharge in which the iron level is still below Class III marine surface water limitation of 0.30 mg/l. Even SOBAC witness Dr. Isphording confirmed that there are no concerns caused by metals that TBD is adding during the process. Discharge Effect on Metal Absorption/Desorption Dr. Isphording limited his concerns to the reaction of higher salinity, DO, and redox to the sediments already contained within the area beyond the discharge point. Dr. Isphording admits that he cannot quantify what the potential release of heavy metals would be due to these factors. Absorption of metals occurs when an organic or clay particle attracts to its surface a metal. Biota do not obtain metals if the metal is held in sand or silt size particles. Biota, be they plant or animal, in most cases obtain the metals they receive from tiny particles that are suspended in the water called microparticulate material. Microparticulate material is generally referred to as colloidal phase. Typically, this phase is on the order of a tenth of a micron in size. Biota obtain metals only if they are present at clay- size particles. Only 10 percent of the quantity of metals that are theoretically available to the biota in a given environment is actually absorbed in tissues. Salinity Has Little Effect on Metals Salinity does not exert a controlling influence on absorption/desorption reactions except at very low salinities. If the salinity is zero, which is essentially a pure freshwater environment, and the salinity level then rises 3 ppt, there would be profound changes in the metal loads, for example, where rivers meet estuaries or seawater. When salinity levels in the water are on the order of 25 ppt, small salinity perturbations such as 2.5 ppt will have a very small effect on absorption/desorption reactions. In fact, the influence can be either positive or negative, but in general they are going to be quite small. Potential releases or gains of metal from salinity changes of 2.5 ppt, at the area of the discharge canal, would be difficult to predict, and it is uncertain whether the change would be positive or negative. pH Will Have Virtually No Effect on Metals Although SOBAC witness Dr. Isphording knew of no change to pH caused by the desalination process, he testified to the alleged effect of lowered pH on the metal in the sediments and water column. Only large pH differences can have a significant influence on absorption or desorption of metals. Any effect on absorption from a decrease in pH on the order of a tenth of a pH unit will be hidden within the natural variations of the estuarine system. See Finding 140, supra. Effect of Lower Oxygen Levels on Metals Redox is basically an oxidation-reduction phenomenon. In order for the low levels of oxygen to have a reducing effect resulting in a release of metals from sediments, virtually all of the oxygen would have to be removed from the water. Basically, the environment would have to reach anoxic conditions. Even then, some metals such as copper would remain within the sediments. In an oxygen-buffered system, redox perturbations will not significantly or measurably mobilize metals. Sediments can be oxidizing in the upper part and then generally become more reducing at depth. The area near the desal discharge does not have organic-rich deep sediment. Proposed Discharge Effect on Bioavailability of Metals The proposed desalination plant's discharge will not increase the bioavailability on metals above that of natural variations and any changes would be hard to discern or measure. Nor will there be any appreciable accumulation of metals in sediments in the receiving water resulting from the proposed desalination discharge. DEP has not established any sediment quality standard and monitoring of sediments is not a NPDES requirement. The desalination plant does not result in violations of Class III marine surface water criteria and standards. No Synergistic Effects Caused by Discharge There are no synergistic effects from the proposed discharge wherein the combination of two elements such as temperature and salinity together would create a new effect. Instead, pH, redox, salinity, and temperature may have small, immeasurable effects that may offset each other. No Adverse Impacts to Biota Comprehensive species lists of phytoplankton, zooplankton, benthic macroinvertebrates, fish, aquatic flora (including seagrasses and mangrove species), and threatened or endangered species inhabiting the area were prepared based on extensive review of applicable scientific literature on Tampa Bay. The salinity tolerance ranges of these species were determined through extensive review of information on salinity ranges associated with species capture, laboratory studies, review of studies addressing species types and salinity tolerances in hypersaline estuaries, and species salinity tolerances determined for other desalination projects. When background salinity is above 10 ppt, changes in salinity of a few ppt have no effect on most organisms. Lower salinities are more detrimental than high salinities to most marine organisms, as long as the upper limit does not exceed a value of approximately 40 ppt salinity. Most planktonic species and life forms can tolerate salinities of up to 40 ppt. Mangrove and seagrass species living in the area can tolerate salinity levels as high as 60 ppt. Benthic macroinvertebrates in the area routinely experience, tolerate and survive in salinity levels ranging from approximately 6 ppt to over 39 ppt under natural environmental conditions. Fish species in the area routinely experience and tolerate salinity levels as high as 39 to 40 ppt under natural environmental conditions. Estuaries serve as fish nurseries because fish species lay their eggs in estuaries, and the larval and juvenile life stages live and mature in estuaries. Due to extreme range of conditions that naturally occur in estuaries, fish reproductive strategies have adapted to enable fish eggs and larval and juvenile life stages to tolerate the wide range of natural conditions, including ranges in salinity levels, that are endemic to estuaries. Egg, larval, and juvenile fish stages may be better able to tolerate extreme range of salinities than adults life stages. A 2.5 ppt increase in salinity and the permitted maximum increase of 10 percent above the intake chloride level is within the range of tolerance and variability that seagrasses, mangrove species, benthic macroinvertebrates, biota, fishes, manatees, zooplanktonic and phytoplanktonic species, and other organisms and life forms living in Tampa Bay routinely encounter and tolerate in the natural environment. A 2.5 ppt increase in salinity with the maximum permitted salinity discharge limit of 35.8 ppt of salinity and the permitted maximum increase of 10 percent above the intake chloride level will not adversely affect the survival or propagation of seagrasses, mangroves, benthic macroinvertebrates, biota, zooplankton, phytoplankton, fish, fish eggs, or juvenile life stages of fish species, or other organisms or life forms in Tampa Bay, and specifically the portion of Tampa Bay in the vicinity of the desalination plant discharge. The Shannon-Weiner Index, which is a biological integrity index codified at Rule 62-302.530(11), requires that the index for benthic macroinvertebrates not be reduced to less than 75 percent of established background levels. Since there will be no adverse impacts to benthic macroinvertebrates due to the desalination discharge and since the level of salinity increases anticipated will tend to benefit benthic macroinvertebrates population, TBD has met the criterion in Rule 62-302.530(11). The Mote Marine Laboratory data showed that Tampa Bay experienced a 2.0 ppt change in salinity over the course of one month. No fish kill or observable die-offs of species were observed or reported from this natural occurrence of elevated salinity. The desalination discharge will (1) not adversely affect the conservation of fish and wildlife, including endangered species, or their habitats, (2) not adversely affect fishing or water-based recreational values or marine productivity in the vicinity of the proposed discharge, (3) not violate any Class III marine water quality standards, and (4) maintain water quality for the propagation or wildlife, fish, and other aquatic life. The desalination discharge meets the antidegradation standards and policy set forth in Rules 62-4.242 and 62- 302.300. Discharge Disposal Options Analyzed As part of the permitting process, TBD demonstrated that the use of land application of the discharge, other discharge locations, or reuse of the discharge was not economically and technologically reasonable, pursuant to Rule 62-4.242. TBD submitted a sufficient analysis of these options as part of its Antidegradation Analysis. (TBD Ex. 1G; TBD Ex. 200, Fact Sheet, p. 16). Further Protection in the Permit The permit review of the desalination permit application is one of the most thorough ever conducted by DEP. The proposed permit has conditions which create and provide a wide margin of environmental protection. The permit sets effluent limitations of various constituents which are reasonably expected to be in the desal facility discharge and provides for monitoring programs to ensure compliance with those effluent limitations. The monitoring requirements of the proposed permit exceed the monitoring requirement imposed on other facilities in the Tampa Bay area. Effluent Limitations DEP established effluent limitations using the Class III marine state water quality standards, data provided from the pilot plant regarding the chemical characterization, the modeling conducted by DHI and the University of South Florida, and the water quality data collection by Mote Marine Laboratory in connection with the establishment of the WQBEL. The effluent limitations contained in the permit are consistent with DEP rules. The proposed permit restricts TBD to the lesser of either the chloride limit of 10 percent above intake or the salinity limit of 35.8 ppt. There is no state water quality standard for salinity. The permit limit for chlorides complies with Rule 62- 302.530(18). The permit's additional requirement of a minimum dilution ratio has the effect of limiting chlorides to 7 percent above intake for 384 hours per year and 5 percent above intake for the remainder of the year and thus provides extraordinary assurance that the state water quality standard for chlorides will be met. Dr. Champ was SOBAC's primary witness in support of its argument that the proposed permit allows a discharge with excessive salinity. But it was apparent from his testimony that Dr. Champ misinterpreted the permit limitations for salinity. See Finding 196, infra. Dr. Champ conceded that the chloride limit of 10 percent above intake was appropriate but focused on the 35.8 ppt maximum, as if it overrode the chloride limitation. As found, the opposite is true. TBD will be limited to 10 percent above intake for chlorides even if the result is salinity far less than the daily maximum of 35.8 ppt. Dr. Champ also had concerns about comparing the discharge to intake chloride levels as not being representative of "normal background." He argued (as does SOBAC) for comparing discharge to chloride levels somewhere else in Middle Tampa Bay, nearby but far enough away to insure no influence from the discharge. But the modeling evidence provided reasonable assurance that there will not be a great deal of recirculation of discharge to intake and that the recirculation expected will not cause salinity to build-up continuously over time. The modeling evidence is accepted as far more persuasive than Dr. Champ's testimony. See Finding 196, infra. The only metals for which effluent limitations were established in the permit are copper, nickel, and iron because these were the only metals determined to be close to the state water quality standard levels by the pilot plant studies. The actual levels of such metals in the desalination discharge will be less than those in the pilot plant testing because the dilution ratio (12.8 to 1) used in the pilot testing is much higher than the minimum dilution ratio required by the permit (20 to 1). The permit effluent limitations for copper, nickel, and iron are based on, and comply with, DEP Rules 62- 302.500(2)(d) and 62-302.530(24), (39) and (45). The permit effluent limitations for Gross Alpha are based on and comply with the requirements in Rule 62- 302.530(58). Biological treatment of the desalination plant discharge concentrate is not required because it consists of seawater. Monitoring for Effluent Limitations DEP is able to separately determine TEC's compliance with its permit from TBD's compliance with the effluent limitations in the proposed desalination permit because of how the facility is designed and the monitoring is constructed. Monitoring requirements in the proposed permit were determined with reference to the probability of desal facility discharge exceeding specific water quality standards. DEP rules do not require monitoring for each and every constituent detected above background concentrations, only those which would probably exceed state water quality standards. The permit requires monitoring of effluent limitations at the intake to and discharge from the desalination facility and the calculation of the diluted effluent levels in the co-mingled discharge water. In order to calculate the effluent components in the diluted discharge water, continuous monitoring is performed on the TEC cooling water discharge rate of flow. Parameters of DO, conductivity, salinity, chlorides, copper, iron, nickel, radium, gross alpha, and effluent toxicity are measured at both intake and discharge pursuant to proposed permit. Monitoring of Intake Monitoring of the intake will be located, after interception off TEC Units 3 and 4, prior to entering the desalination plant. Using a sampling location of the intake to the desalination facility prior to filtering or chemical addition for background samples is consistent with the definition of "background" in DEP Rule 62-302.200(3). EPC Stations 11, 80, 81, 13, and 14 are not proper locations for background samples because salinity varies with tides and depth and those stations are too distant from the actual intake point. EPC station 9 is not a good location because it is closer to the discharge than the permit sample point. Monitoring of Discharge Monitoring of the discharge will take place in the wet well prior to discharge into TEC's cooling water discharge tunnels. This monitoring location is in compliance with Rule 62-620.620(2)(i) which provides for monitoring of effluent limitations in internal waste streams. Monitoring of the desal facility discharge concentrate in each of the four cooling water discharge tunnels is impractical due to the high volume of dilution and addition of four potential discharge locations. Once the desal facility concentrate is diluted by the TEC cooling water discharge, it is much more difficult to obtain accurate water quality testing for constituents at such minute levels. Monitoring of the Combined Discharge Concentrations Calculations determine the mixing ratios of the desalination concentrate with TEC's cooling water. Using the flow data from TEC, the calculations will accurately determine the water quality of the co-mingled discharge water. Compliance with Permit Effluent Limitations The proposed permit requires TBD to monitor constituents for which there are effluent limitations on either a daily, weekly or monthly basis, depending on the constituent. The frequency of monitoring for each constituent is based on comparing the expected levels of the constituent to the water quality standard and analyzing the probability of the desal facility discharge exceeding that standard. The monitoring provides additional assurances beyond the pilot plant studies, testing and modeling that no water quality standard will be violated. Continuous monitoring is not necessary to successfully monitor discharges. Monthly measurements are sufficient to determine compliance even for a daily permit level because the chemical characterization studies provide reasonable assurances that the desalination concentrate will not exceed the effluent limitations. Monthly monitoring provides further checks and balances to assure that the desalination discharge is in conformance with the effluent limitations and DEP rules. The EPA only requires that monitoring occur at least once a year. Conductivity provides a direct correlation to salinity and chlorides. Measuring conductivity provides salinity and chloride levels by basis of calculations and is typically used as a surrogate for monitoring chloride and salinity continuously. Salinity and chloride cannot themselves be measured continuously because they are measured by lab tests. The permit requires conductivity to be monitored continuously, not because DEP believed the desalination discharge would be near the chloride limitation, but rather to be extremely conservative. The permit conditions treat an exceedance of salinity or chlorides based on conductivity readings to be a violation of the permit effluent limitations for salinity and chlorides. TBD provided reasonable assurance to DEP that the proposed desalination discharge would not violate the DO water quality standards and criteria in Rules 62-302.530(31) and 62- 302.300(15). The permit condition requiring monitoring of DO provides verification that desal facility discharge will meet the DO water quality standards. Even SOBAC's witness Dr. Champ admitted that a continuous measurement for DO is not as valuable as random weekly samples. External Monitoring Programs The proposed permit requires TBD to develop and submit to DEP a Biological Monitoring Program to monitor seagrasses, benthic macroninvertebrates and fish populations to be consistent with existing Tampa Bay monitoring programs. This program will provide an effective means of monitoring the potential impacts of the desalination discharge. The proposed permit also requires TBD to implement a Water Quality Monitoring Program for three monitoring stations located proximal to the intake, the discharge and the North Apollo Beach Embayment which will monitor conductivity, salinity, DO and temperature continuously. These monitoring programs will provide additional ambient data to DEP. If the data indicate an exceedance or reasonable potential for an exceedance of water quality standards, DEP may reopen the permit in accordance with the reopener clause contained in the permit. These monitoring programs go beyond the requirements in DEP rules. Additionally, DEP does independent monitoring of NPDES discharges without notice and on a purposely unpredictable basis. Proof of Financial Responsibility Rule 62-620.301(6) addresses when DEP may require a permit applicant to submit proof of financial responsibility to guarantee compliance with Chapter 403, Florida Statutes. TBD's compliance history was taken into consideration during the permitting process. Adequate financial assurance were provided in the permit application. (TBD Ex. 1I). Further, the permit conditions added by the settlement agreement (TBD Ex. 470) provide for additional financial assurance beyond those that can be required by the NPDES program and DEP rules. Additional Comment on SOBAC's Evidence As already indicated, SOBAC elicited the testimony of several expert witnesses at final hearing to support its contentions. But none of SOBAC's experts spent a great deal of time studying TBD's desal project, especially compared to witnesses for the other parties. Mostly, SOBAC experts expressed general scientific principles that were not directly tied to specifics of the desal project or were very general expressions of concern. Often, SOBAC's experts were not familiar with all the efforts of experts offered by the other parties to address those very concerns. Except for Dr. Champ, no SOBAC expert opined that the proposed permits would result in violations of DEP statutes and rules. Some SOBAC experts expressed opinions that only would be relevant if there were insufficient assurances in proposed permits that DEP statutes and rules would not be violated. Statistical evidence presented was not particularly relevant. Dr. Goodwin As previously mentioned, Dr. Carl Goodwin was willing to provide testimony on work he did for the USGS, but he gave no expert opinions on the permits which are the subject of these proceedings. As also previously discussed, his two- dimensional model studies were constrained by computational limitations. Even so, his studies indicated that flushing in Tampa Bay was becoming more rapid in recent years. In addition, even if the "gyres" suggested by his two-dimensional studies actually existed, they would tend to promote mixing in Tampa Bay in area of the Big Bend power plant. Dr. Champ Dr. Champ's first opinion was that 35.8 ppt is too high a salinity limit and would result in "oceanic" conditions. He attempted to compare this result to results of diversion of substantial amounts of freshwater inputs to the Black Sea for agricultural purposes--a totally different situation not suitable for comparison to Tampa Bay. Initially, Dr. Champ suggested a limitation of a 10 percent increase above "background" or "ambient" conditions; it was apparent that initially Dr. Champ was not cognizant of the 10 percent over intake chloride limitation in the proposed permit. When he was made aware of the chloride limit, he misinterpreted the two limits, saying that TBD would not be limited to the lower of the two. When it was suggested that he might have misinterpreted the two salinity limits, Dr. Champ testified that chlorides should be compared to a "natural" or "environmental" control site somewhere nearby but outside the influence of the combined TEC/TBD discharge; he said it was a "farce" to compare chlorides to a control site "inside the plant." In so doing, he seemed not to recognize the purpose of the comparison made in the proposed permit--to isolate and identify the impacts of TBD's desal process. In addition, dismissing without much consideration the contrary results of extensive and sophisticated modeling, Dr. Champ opined off- handedly that DO would decrease due to higher salinity that would recirculate and build-up over time. In part, Dr. Champ based this opinion on his misunderstanding that Tampa Bay is not well-mixed or well-circulated at the location of the Big Bend power plant. This was contrary to all the evidence; even if the "gyres" predicted by Dr. Goodwin's two-dimensional model existed, they would suggest a great deal of mixing in Middle Tampa Bay in the vicinity of the Big Bend plant. Dr. Champ next misinterpreted the DO limits in the proposed permit. See Finding 133, supra. Dr. Champ then predicted a decrease in species diversity as a result of higher salinity and lower DO. (To the contrary, salinity increases in the amounts predicted by the far greater weight of the evidence probably would result in somewhat of an increase in species diversity.) Ultimately, Dr. Champ testified that consequences to marine organisms would be dire, even if salinity increased only by 2.5 ppt, because a "salinity barrier" would form across Middle Tampa Bay in contrast to more gradual natural changes in salinity. The far greater weight of the evidence was to the contrary. Dr. Champ made several suggestions to avoid the calamitous results he predicted: require use of a cooling tower to reduce the temperature of the combined TEC/TBD discharge; collect the desal brine concentrate and barge it to the Gulf of Mexico; require intake and discharge pipes extending into the shipping channel in Middle Tampa Bay. But Dr. Champ did not study or give a great deal of thought to implementation of these suggestions. Besides, the other parties proved that these measures were not needed for reasonable assurances. In an attempt to buttress his opinion testimony, Dr. Champ also testified (along with SOBAC's President, B.J. Lower) that the TEC intake canal is virtually devoid of life and that biodiversity in the discharge canal is very low. This testimony was conclusively refuted by the rebuttal testimony of Charles Courtney, who made a site visit after SOBAC's testimony and described in detail a significant number of healthy species in the intake canal, including oyster communities, xanthid crabs, porcellanid crabs, snook, anemones, bivalves, polychaete, and mangroves with seedlings. Of the one and one- half pounds of oysters that Mr. Courtney sampled, he estimated that approximately fifty percent of those oysters were living, which represents a very healthy community. Mr. Courtney further noted that some of the crabs were carrying eggs, which indicates an active life cycle for those species. As to the TEC permit modification, Dr. Champ testified that it was “in-house stuff” which would not affect the environment outside the TEC plant. No other SOBAC witness addressed the TEC permit modification. Dr. Isphording SOBAC called Dr. Wayne Isphording as an expert in sedimentology and geochemistry. Dr. Isphording expressed no concern that the desal process would add metals to Tampa Bay. Essentially, he gave opinion testimony concerning general principles of sedimentology and geochemistry. He testified that heavy metals bound in sediments are released naturally with increases in salinity, but that salinity levels would have to be extreme to result in the release of abnormal quantities of such metals. He admitted that he had performed no studies of sediments in Tampa Bay and declined to offer specific opinions that metals in fact would be released as a result of predicted salinity increases. Dr. Isphording admitted that he knew of no condition in the proposed Desal Facility permit which would cause or allow a violation of state water quality standards. He was aware of no statute or rule requiring more monitoring and testing than is required in the proposed permit. Dr. Parsons SOBAC offered the testimony of Dr. Arthur Rost Parsons, an assistant professor of oceanography at the Naval Postgraduate School, in an attempt to raise questions regarding the near-field and far-field modeling which were provided by TBD to DEP during the course of the permitting process. However, not only had Dr. Parsons not done any modeling in Tampa Bay himself, he was not provided numerous reports and clarifications relating to the studies he was called to critique. He only reviewed an interim report dated November 1, 2000, regarding the near-field model. Dr. Parsons testified that the DHI model used for the near-field study was an excellent shallow water model. He found nothing scientifically wrong with it and testified that the "physics and the model itself is . . . well–documented." Dr. Parsons also did not contradict the results of the DHI model. Instead, he noted that the modeling task was difficult and complex, he described some of the model's limitations, and he testified to things that could have been done to increase his confidence in the model results. One of Dr. Parson's suggestions was to run the model longer. But the evidence was that, due to the model's complexity and high computational demands, it would have been extremely expensive to run the model for longer periods of time. Another of Dr. Parson's suggestions was to use salinity data would be to use the information that the model itself generated with regard to salinity distributions instead of a homogeneous set of salinity data. Dr. Parsons was concerned that use of homogeneous salinity data would not reflect the effect of "double diffusion" of heat and salinity, which would result in sinking of the combined heat. But engineer Andrew Driscoll testified in rebuttal that the effects of "double diffusion" would cease once equilibrium was reached and would not result in a hypersaline plum sinking to the bottom. In addition, he testified that turbulent mixing from tide and wind would dominate over the effect of "double diffusion" at the molecular level so as to thoroughly mix the water, especially in the shallow North Apollo Beach Embayment. Dr. Parsons also suggested that the model be run for rainy season conditions to see if the effects of vertical stratification would increase. But even if vertical stratification increased as a result of rain, salinity also would be expected to decrease. The scenario modeled was "worst case." Dr. Parsons also suggested the use of a range of temperatures for the combined heat/salinity plume instead of an average temperature. However, he conceded that it was not inappropriate to use average temperature. Instead, he would have liked to have seen the model run for a range of temperatures to see if the model was sensitive to temperature differences so as to increase his confidence in the results. Dr. Parson's testimony focused on the near-field model. His only comment on the far-field model was that he thought it should have used the out-puts from the near-field model (as the near-field used the outputs). Scott Herber SOBAC offered no direct testimony on the impact of the Desal Facility discharge on seagrasses in Tampa Bay. The testimony of Steve Herber, a doctoral student at the Florida Institute of Technology, related to the vulnerability of seagrasses, in general, to changes in salinity. However, Mr. Herber had no specific knowledge of the seagrasses present in Tampa Bay and had not performed or reviewed any scientific studies upon which his opinion could be based. He reached no conclusions about the specific permits at issue in this proceeding, nor about the effect of the Desal Facility on seagrasses in Tampa Bay. In contrast to Mr. Herber, the testimony of TBD's expert, Robin Lewis, and SWFWMD's expert, Dr. David Tomasko, provided detailed information about the seagrasses located in Tampa Bay. Both have studied seagrasses in Tampa Bay for many years and have been involved in mapping seagrass distribution in a variety of bays and estuaries along the west coast of Florida. Dr. Tomasko criticized witnesses for SOBAC who attempted to draw conclusions about Tampa Bay based on studies of other bays and estuaries because each bay has unique characteristics that cannot be extrapolated from studies of other bays. Dr. Tomasko and Lewis testified that seagrasses in Tampa Bay are becoming more abundant, that dissolved oxygen levels are increasing, and that water clarity in Tampa Bay is also improving. Dr. Mishra Dr. Satya Mishra was called by SOBAC as an expert in statistics. He is not an expert in the discrete field of environmental statistics. He has never been involved in the development of a biological monitoring program and could not provide an opinion regarding what would be an adequate sample size for this permit. He essentially expressed the general opinions that for purposes of predictive statistical analysis: random sampling is preferred; statistical reliability increases with the number of samples; and 95 percent reliability is acceptable. Dr. Mishra performed no statistical analysis in this case and could not conclude that the sampling provided in the proposed permit would not be random. Ron Chandler Ron Chandler, a marketing representative for Yellow Springs Instrument Corporation (YSI), simply testified for SOBAC regarding the availability of certain types of continuous monitoring devices. He did not offer any opinions regarding whether or not reasonable assurance required continuous monitoring of any specific parameter or any monitoring different from or in addition to what is proposed in TBD's proposed permit. John Yoho SOBAC called John Yoho as a financial and insurance expert to criticize the terms of an agreement by TBD, TBW, and DEP to settle Hillsborough County's request for an administrative hearing (DOAH Case No. 01-1950). This agreement is contained in TBD Ex. 470. But Yoho admitted that he had no knowledge regarding what is required to obtain an NPDES permit in terms of financial assurances. He also indicated that none of his testimony should be understood as relating in any way to financial assurances required for such a permit to be issued. Alleged Improper Purpose The evidence did not prove that SOBAC participated in DOAH Case No. 01-2720 for an improper purpose--i.e., primarily to harass or to cause unnecessary delay or for frivolous purpose or to needlessly increase the cost of licensing or securing the approval of TEC's permit modification applications. To the contrary, the evidence was that SOBAC participated in this proceeding in an attempt to raise justifiable issues arising from the peculiarities of the relationship of TEC's permit modification application to TBD's permit application. Although SOBAC suffered adverse legal rulings that prevented it from pursuing many of the issues it sought to have adjudicated on TEC's permit modification application, it continued to pursue issues as to the TBD permit application which, if successful, could require action to be taken on property controlled by TEC and, arguably, could require further modification of TEC's permit.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Florida Department of Environmental Protection enter a final order: (1) issuing the proposed permit number FL0186813-001-IWIS, as set forth in TBD Ex. 203 with the addition of the two permit conditions specified in TBD Ex. 470; (2) issuing proposed permit modification number FL0000817-003-IWIS, as set forth in TBD Ex. 225; and (3) denying TEC's request for attorney's fees and costs from SOBAC under Section 120.595(1). Jurisdiction is reserved to enter an order on TBD's Motion for Sanctions filed on August 13, 2001, regarding SOBAC expert Ralph Huddleston.

The Issue The issue in this case is whether the Petitioner has the actual experience required for certification as a Class B domestic wastewater treatment plant operator.
Findings Of Fact By application filed September 16, 1991, James H. Redden applied for certification as a Class B domestic wastewater treatment plant operator. At the time of the application, Mr. Redden was employed as a laboratory technician at a Class B Collier County regional wastewater treatment facility. From August 15, 1978, to July 31, 1989, Mr. Redden was employed at the Colgate-Palmolive Company facility at Jeffersonville, Indiana. The Colgate-Palmolive treatment facility is an Indiana Class D industrial wastewater treatment plant. Mr. Redden is certified by the State of Indiana as a Class D industrial wastewater treatment plant operator. During his employment at the Jeffersonville facility, Mr. Redden held positions as an associate chemist, senior chemist/plant microbiologist, and wastewater treatment plant supervisor. His duties included daily operations and supervision of personnel, scheduling and performance of maintenance activities, budgeting, ordering, materials balance, sludge management, laboratory analysis, quality assurance and quality control programs, and compliance with various state and federal reporting requirements. Mr. Redden has no experience either in the operation of a drinking water or domestic wastewater treatment plant, or at a DER-permitted industrial wastewater treatment plant.
Recommendation Based on the foregoing, it is hereby: RECOMMENDED that the Department of Environmental Regulation enter a Final Order denying the application of James H. Redden for certification as a Class B wastewater treatment plant operator. DONE and RECOMMENDED this 9th day of April, 1992, in Tallahassee, Florida. WILLIAM F. QUATTLEBAUM Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 9th day of April, 1992.

The Issue The issue presented is whether Respondent Seanic Corporation's application for an operating permit for a domestic wastewater treatment facility should be granted.
Findings Of Fact On January 20, 1994, Respondent Seanic Corporation submitted to Respondent Department of Environmental Protection an application to construct a wastewater treatment and disposal facility. The application requested approval to construct a facility with a design capacity of 15,000 gallons per day and to discharge its treated effluent to G-III groundwater through two Class V injection wells. Although the Department had no rules with specific depth requirements for such wells, the plans that accompanied the application contemplated wells with a total depth of 90 feet below land surface, which would be cased down to a depth of 60 feet below land surface. On February 23, 1994, the Department gave notice of its intent to issue the requested construction permit. Petitioners did not challenge the issuance of the construction permit, and the Department issued the permit on April 22, 1994, with an expiration date of five years after the issuance of the permit. On February 17, 1999, Seanic began construction of the permitted facility, including the construction of the two Class V injection wells. At the time the wells were first drilled, there were no statutes or rules regarding the appropriate depth of underground injection wells at a facility like Seanic's. Construction of the Seanic facility was completed before April 12, 1999, as reflected by the Certificate of Completion of Construction for the permitted facility. On April 21, 1999, Seanic filed with the Department its application to operate the facility. Chapter 99-395, Laws of Florida, became effective on June 18, 1999, approximately two months after the facility was constructed and the operating permit application was submitted. Section 5 of Chapter 99-395 defines the term "existing" to mean "permitted by the Department of Environmental Protection or the Department of Health as of the effective date of this act." Chapter 99-395 imposes different effluent limitations for "existing sewage facilities" than those that are applied to new facilities. For facilities that have a design capacity of less than 100,000 gallons per day, new facilities must provide treatment that will produce an effluent that contains no more, on a permitted annual basis, than the following concentrations: Biochemical Oxygen Demand (CBOD5) of 10 mg/L Suspended Solids of 10 mg/L Total Nitrogen of 10 mg/L Total Phosphorus of 1 mg/L These standards are frequently referred to as the "10-10-10-1 Standard." In accordance with Section 6(4) of Chapter 99-395, "existing sewage facilities" have until July 1, 2010, to comply with the 10-10-10-1 standard. Prior to that date, "existing sewage facilities" must meet effluent limitations of 20 mg/L for both CBOD5 and suspended solids and must monitor their effluent for concentrations of total nitrogen and total phosphorus. The Seanic facility is an "existing" facility, as that term is defined in Chapter 99-395, and, therefore, has until July 1, 2010, to comply with the 10-10-10-1 standard. Section 6(7)(a) of Chapter 99-395 requires Class V injection wells for facilities like Seanic's to be "at least 90 feet deep and cased to a minimum depth of 60 feet or to such greater cased depth and total well depth as may be required by Department of Environmental Protection rule." The Department has not promulgated any rules requiring Class V injection wells to be deeper than the depth prescribed in Chapter 99-395, Laws of Florida. As of January 26, 2000, the total depth of Seanic's injection wells measured 92 and 94.5 feet, respectively. On November 24, 1999, the Department entered its notice of intent to issue the operating permit applied for by Seanic and attached to the notice a "draft permit" with the conditions and effluent limitations that would be applied to the facility. In issuing the notice, the Department determined that Seanic had provided reasonable assurance that the facility will not discharge, emit, or cause pollution in contravention of applicable statutes or the Department's standards or rules. The draft permit included effluent limitations of 20 mg/L for both CBOD5 and suspended solids and required Seanic to monitor its effluent for total nitrogen and total phosphorus, in accordance with Chapter 99-395, Laws of Florida, and the Department's rules for existing sewage facilities. The draft permit notes that Seanic must comply with the 10-10-10-1 standard by July 1, 2010. Because Seanic's condominium development has not been completed and the wastewater treatment facility is not expected to go into operation for approximately one year, the draft permit also requires that the facility be re-inspected and re-certified immediately prior to going into operation. The Seanic facility was designed to create an effluent that is several times cleaner than required by Department rules. The facility uses an extended aeration process that is expected to reduce levels of both biological oxygen demand ("BOD") and total suspended solids ("TSS") to lower than 5 mg/L, concentrations that are 75 percent lower than the effluent limitations in the draft permit. Similar facilities in the Florida Keys have shown that they can achieve BOD and TSS concentrations of less than 5 mg/L. The Seanic facility has also been designed to provide a greater level of disinfection than required by law. While the draft permit requires only that the facility maintain a chlorine residual of 0.5 mg/L after fifteen minutes' contact time, the facility has been designed with larger chlorine contact tanks to provide a chlorine contact time of approximately one hour at anticipated flow rates. The facility operator can also increase residual chlorine concentrations. These facts, along with the reduced TSS levels at this facility, will provide considerably greater levels of disinfection than the law requires. Although the draft permit does not contain effluent limitations for total nitrogen or total phosphorus, the levels of these nutrients expected to be present in the Seanic facility's effluent are approximately 5 mg/L and 2-3 mg/L, respectively. Studies conducted on the rate of movement of phosphorus in the subsurface indicate that some of the phosphorus is rapidly immobilized through chemical reactions with the subsurface soil matrix. Specifically, studies conducted on injection wells in the Florida Keys report that 95 percent of the phosphorus is immobilized within a short time after entering the injection well. Studies conducted on the rate of movement of nitrates in the subsurface indicate that some nitrate migration is also retarded through chemical reactions with the subsurface soil matrix. More specifically, studies conducted with injection wells in the Florida Keys report that denitrification removes approximately 65 percent of the nitrates within a short time after the effluent enters the injection well. In addition to the chemical reduction of phosphorus and nitrogen levels in the groundwater, studies conducted on injection wells in the Florida Keys with a total depth of 90 feet and a cased depth of 60 feet have reported extremely high dilution rates by the time effluent injected into such wells would appear in surrounding surface waters. More specifically, studies using chemical and radioactive tracers have reported dilution rates on the range of seven orders of magnitude, i.e., 10 million times. After undergoing chemical reduction in the groundwater as well as extremely high dilution rates, the levels of nitrogen and phosphorus that would be expected to enter Captain's Cove and the adjacent canals will be infinitesimal, i.e., less than one part per trillion. Such levels would be several orders of magnitude below detection limits of currently available analytical methods. The surface waters in the artificial canals and in Captain's Cove surrounding the homes of Petitioners' members are classified by the Department as Class III waters that are predominantly marine. The permitted levels of fecal coliform bacteria in the facility's effluent (as restricted in the draft permit) are identical to the discharge limits for fecal coliform bacteria in Class III waters that are predominantly marine. The operation of Seanic's facility will not result in discharges of fecal coliform bacteria in excess of the applicable effluent limitations. Petitioners' expert witnesses agree that the facility, as designed, will comply with all of the conditions and effluent limitations in the draft permit. No Department rule or standard will be violated by this facility. The Department has not promulgated any effluent limitations or standards for viruses to be discharged to G-III groundwater or Class III surface waters that are predominantly marine. Petitioners' members use and enjoy the clear waters in their canals and in Captain's Cove. They have had the water quality tested four times a year since 1988. Captain's Cove, along with the adjacent canals, has remained a clear, oligotrophic water body with minimal algae growth. Petitioners' members fear that the introduction of viruses and other microorganisms through the facility's effluent will cause swimming in Captain's Cove and the adjacent canals to be harmful to their health. Their fear has been heightened by newspaper stories about viruses and a publicized study which erroneously claimed that Captain's Cove had high levels of harmful bacteria. Petitioner Port Antigua Property Owners Association ("PAPOA") received notice of the Department's intent to issue an operating permit to Seanic. The president discussed the permit with another resident, a microbiologist, who in turn discussed the facility with geologists and reviewed studies performed in the Florida Keys. Their serious concern over the depth of the injection wells and the possible release of viruses and bacteria harmful to the marine environment and to the public health was expressed throughout PAPOA's petition, and a copy of one of the tracer studies upon which they relied was attached to the petition. The president of Petitioner Port Antigua Townhouse Association, Inc. ("PATA"), who is also a member of PAPOA, discussed the Department's notice of intent with the president of PAPOA and the microbiologist. He also discussed the project with a member of PATA who oversees Broward County's wastewater treatment facility, which has the same effluent limitations as the Seanic facility. PATA members believed they should join with PAPOA and the Lower Matecumbe Key Association in requesting a hearing on Seanic's operating permit. PATA and others have also filed litigation in the Circuit Court against Seanic Corporation and others. That litigation is still pending. Petitioners were not able to cite any statute or rule that would be violated by the Seanic facility's discharge. They believe that since the facility is not yet operating, it should be required to adhere to the stricter effluent standards required for new facilities. They also believe that the Department should consider the harmful effects of viruses and bacteria on the marine environment and on the public health. Petitioners did not file their petitions for any improper purpose. They did not file their petitions for any frivolous purpose or to harass or to cause unnecessary delay or to increase Seanic's costs in obtaining an operating permit for its facility. They believed the language in the Department's notice of intent to issue the permit which advises substantially affected persons that they have a right to an administrative hearing and that the Department could change its preliminary agency action as an result of the administrative hearing process. They believe they are simply exercising a right that they have under the law.

The Issue The ultimate issue to be resolved in this proceeding is whether the Department should issue a permit allowing the construction of a wastewater treatment and disposal system as requested in the modified application filed by Thomas E. Wasdin. The applicant and the Department contend that reasonable assurances have been given that the proposed facility will not result in violations of any of the Department's rules or regulations. The Petitioner contends that the proposed facility is located too near to existing shallow water drinking wells and that the facility otherwise fails to comport with the Department's rules and regulations.
Findings Of Fact Petitioner is the president of Beach Woods of Brevard County, Inc. The corporation is the developer of "Beach Woods," a 376-unit planned unit development located in Melbourne Beach, Brevard County, Florida. One hundred eighty of the units have already been developed. Existing regional sewage treatment facilities operated by Brevard County are not adequate to accommodate the total number of units that the applicant proposes to develop. It appears that 24 more hookups are all that the existing facilities will tolerate. Beyond that number, a sewer moratorium is in effect, and unless the applicant can make some other arrangement for disposing of sewage, the development cannot be completed. The county has approved the planned unit development. In order to meet sewage treatment needs of the proposed development, the applicant is proposing to construct a "package sewage treatment plant" to accommodate waste that exceeds quantities that can be handled by existing regional facilities. Once the regional facilities are upgraded so that the development's sewage treatment needs can be accommodated, the applicant proposes to disassemble the package plant and utilize the regional facilities. The proposed plant would be a 50,000 gallons per day contact stabilization sewage treatment plant. Initially, it would be operated as a 5,000 to 15,000 gallons per day aeration plant. Once loads reach 18,000 gallons per day, it would become a contact stabilization plant. The Present collection and transmission system for sewage that exists at Beach Woods includes an 8-Inch collection station from which sewage flows to an existing lift station that pumps effluent via 6-inch pipes to the regional plant. When the proposed plant is completed, a computerized system would be set up to send effluent to the new plants when the limits that the regional plant can accommodate are met. Once the regional plant is upgraded to sufficient capacity, the bypass to the proposed plant would be eliminated, and all units would then be connected to the original collection system. The proposed treatment plant is based upon proven technology that has been in existence for more than 50 years. The plant should operate reliably, and proper consideration has been given to odor, noise, lighting, and aerosol drift. In close proximity to the plant, it is likely that there would occasionally be a "earthy smell" that would be noticeable, but not objectionable. Outside of the immediate proximity, no odor would be noticeable. Large fans would be operated in connection with the plant, and some noise would result. It does not, however, appear that the noise would be excessive or bothersome, even in the immediate vicinity of the plant. The plant would be lighted by street lights and would not result in any more excessive lights than normal street lights. The plant is not of the sort that aerosol drift is a likely problem. Adequate considerations have been given to providing emergency power to the plant in the event of a power outage. The plant could sit for at least 20 hours without power before any emergency would exist. If there was a power outage in excess of that period, emergency power sources are available. Consideration has been given to the 100-year flood plain. The plant has been placed at an elevation that keeps it outside of the 100-year flood plain. The land application system proposed by the applicant would utilize drain fields that would be alternately rested. Groundwater flows from the area of the proposed drain fields are in a southwesterly direction toward the Indian River. The Indian River in the location of the proposed facility is a "Class III surface water." Groundwater in the area of the proposed facility might be classified as either "G-I" or "G-II." Reasonable assurance has been given that the proposed sewage treatment plant would not operate in such a manner as to degrade surface or ground waters to the extent that any of the Department's specific water quality parameters set out in Chapter 17, Florida Administrative Code, would be violated. The proposed sewage treatment plant comports with local requirements and has been approved by Brevard County. The Allans Subdivision is a residential development that is located directly to the north of the Beach Woods development. Petitioner utilizes a shallow water well as a source of drinking water. The proposed land application site of the sewage treatment plant is located within 500 feet of the Petitioner's well. There are at least two other shallow water wells that serve as drinking water sources located within 500 feet of the proposed land application site. The applicant indicated a willingness to move the proposed facility so that no part of it would be located within 500 feet of the shallow drinking water wells. The evidence establishes that the plant could be moved to accomplish that. No specific plan, however was presented. Potential factual issues could exist respecting appropriate buffer zones for any relocation of the facility, even a minor relocation. The applicant is proposing to develop areas within 100 feet of the proposed facility. The applicant does not, however, propose to locate any public eating, drinking, or bathing facilities within 100 feet of the proposed plant or land application area. No map was presented during the course of proceedings before the Department of Environmental Regulation that preceded the formal administrative hearing or during the hearing itself to establish present and anticipated land uses within one mile of the boundaries of the proposed facility. The facility of such a size that it could not inhibit any conceivable present or proposed future land uses except within 500 feet of the proposed facility. Evidence was offered at the hearing from which it could be concluded that the Department has, in the past, issued permits for sewage treatment plants located within 500 feet of existing shallow drinking water wells. The testimony was that this has occurred despite a requirement in the Department's rules that there be a 500-foot buffer zone between any such plant and a shallow drinking water supply. No specific evidence was presented as to why the Department has allowed such a breach of its rules or why it should be allowed in this proceeding.
Findings Of Fact By letter dated August 10, 1979, Indian River County (hereafter "County") submitted to the Department of Environmental Regulation (hereafter "Department" or "DER") applications for construction permits for the Gifford Area sewer treatment plant and collection improvements thereto, a domestic wastewater treatment and disposal system located in the County. (DER Exhibits Nos. 1 & 2). After receiving the permit applications submitted by the County, the Department's Orlando District Office requested additional information to determine whether reasonable assurances were provided that the facility would not discharge, emit or cause pollution in violation of Department standards. (Testimony of William Bostwick; testimony of Chancellor; DER Exhibits Nos. 3, 4, 5, 6, 7 & 8). The County, through its consulting engineers Sverdrup & Parcel and Associates, Inc., responded to the Department's requests for additional information. (DER Exhibits Nos. 3, 4, 5, 6, 7 & 8). The Department presented testimony of two professional engineers in its employ, Mr. William M. Bostwick and Mr. Gerald Chancellor, both of whom were accepted as expert witnesses in the field of sewage treatment technology and the processing and evaluation of permit applications for sewage treatment plants. Both witnesses testified that in their expert and professional opinion, based on their review of all plans, test results and other information submitted by the County, the applicant provided the Department with reasonable assurances that the proposed construction and operation of the sewage treatment facility and its collection system would not discharge, emit or cause pollution in violation of Department standards. (Testimony of Bostwick; testimony of Chancellor). The standards applicable to the subject construction permit applications involve (a) treatment level and (b) ambient standards of the receiving waters. The proposed system provides a minimum of ninety (90) percent treatment to incoming wastewaters. Because of the added features of surge tanks, gas chlorination, and dual blowers and motors, the ninety (90) percent minimum treatment was expected to be exceeded. (Testimony of Bostwick; testimony of Chancellor). The secondarily treated effluent from the proposed sewage treatment plant will be dispersed by spray irrigation. Because the effluent is expected to percolate to area groundwaters, the ambient groundwater standards of Section 17-3.101, Florida Administrative Code are applicable. The discharge from the facility will not cause any violation of the groundwater quality standards of the Florida Administrative Code. (Testimony of Bostwick; testimony of Chancellor; testimony of Aront). Although the design of the plant does not contemplate surfacewater discharge, if it did, it would meet the waste load allocation of Indian River County which permits discharge to surfacewaters. When the treated waste leaves the sprinkler head, it will meet secondary water treatment standards. (Testimony of Bostwick; testimony of Chancellor). In the course of evaluating a permit application for a wastewater treatment plant, the Department considers only Chapter 403, Florida Statutes, and its implementing rules and regulations and does not consider local issues relating to zoning, the propriety of expenditure of public funds or the like. (Testimony of Bostwick). There is presently no state standard regulating permissible levels of viruses in effluent discharged to either surface of groundwaters. Large numbers of viruses exist in the effluent discharged from spray irrigation treatment plants which operate at a ninety (90) percent treatment level. The viruses contained in the discharge remain viable as they percolate through the soil. The greatest concern exists when humans are in physical contact with such discharge. However, the present sewage treatment facility in its existing condition is a greater threat to public health than the proposed spray irrigation system. (Testimony of Dr. Welling, Petitioner's Exhibits Nos. 1, 2 & 3). Research concerning viral standards for effluent discharge is in an experimental stage. The Department is examining this question for possible future rule drafting. Neither the federal government nor any state, with the exception of Maryland, has adopted viral standards. (Testimony of Welling) The design of Use Gifford plant contemplates a series of perimeter monitoring wells through which groundwater samples can be attained and tested for compliance with groundwater standards end the presence of viruses. (Testimony of Aront) The plant will spray irrigate effluent at the rate of one (1) inch per week. Although surface run off is not expected, any that occurs due to heavy rains, etc., will be discharged into a perimeter ditch surrounding the plant. The plant design is formulated to retain effluent on site. (Testimony of Chancellor). There are four (4) different types of soil on the site with a water permeability of moderately rapid to very rapid. These soils have a percolation rate which makes the site suited for the intended purpose provided surface drainage is obtained. On a conservative basis the site could accept up to fourteen (14) inches of water per day or ninety-eight (98) inches per week. (Testimony of Connell; testimony of Eng; DER Exhibit No. 6). The parties stipulated prior to the hearing to the following: The project complies with local zoning laws; and The applicable provisions of law are Sections 403.086, 403.087, 403.088, Florida Statutes, and Rules 17-3.091, 17-4.03, 17-4.07 and 17-4.26, Florida Administrative Code.
Recommendation Upon consideration of the foregoing, it is RECOMMENDED: That the Department issue a construction permit to the County on condition that sample effluent from the monitoring wells on the subject facility be regularly analyzed for compliance with Department rules and the existence of infectious viruses.

Findings Of Fact Kyle Brothers Land Company, Inc. filed its application with the Department of Environmental Regulation to excavate four canals and to unplug two canals which they had already dug within its development in Port Pine Heights located on Big Pine Key, Monroe County, Florida. The application of Kyle Brothers Land Company, Inc. was introduced as Composite Exhibit No. 1 and a plat of the proposed development was introduced as Exhibit 9. The proposed activity would be constructed on Class 3 waters as defined in Chapter 17-3, F.A.C. Test data submitted shows that the water quality of the water in the existing canals meets or exceeds the standards established in Section 17-3.09, F.A.C. The proposed canals, as well as the existing canals, are being developed as residential home sites. Two potential threats exist to the maintenance of water quality standards within the canals. The first threat is the short-term effect of increased turbidity of the waters due to the construction of the proposed activity. The second threat is the long-term effect of the increased pollution of the waters resulting from waste disposal through proposed septic tank systems to be used in the residential home sites adjoining the proposed and existing canals. The permit application appraisal, Exhibit 2, indicates that the short- term effects of increased turbidity could be controlled by the use of plugs, screens, and daily testing for turbidity and dissolved oxygen. The evidence further shows a variance in the depth of the existing canals and the two plugged canals. The two plugged canals and several of the existing canals have a depth greater than the central canal. The variance in depth permits the accumulation of debris and silt in the finger canals which under certain conditions could be stirred up and become suspended in the waters of the canals increasing the turbidity of the canals and violating the water quality standards. To prevent this from occurring these canals would have to be filled to bring them to the depth of the central canal. The long-term threat to water quality in the canals is the introduction into the canals of nutrients and chemicals attributable to surface water runoff and the proposed septic tank systems to be utilized on the residential home sites. Control of surface water runoff can be obtained by backs loping the uplands away from the canals. The control of nutrient loading associated with the septic tank systems is more complex. The Declaration of Restrictions for Port Pine Heights, Exhibit 7, recites that sewage disposal shall be by septic tank or central disposal plant. However, the plans submitted by the Applicant do not indicate any provision for establishment of a central disposal plant. Further, under the provisions of the deed restrictions there is no requirement that a resident of Port Pine Heights use a central disposal plant even if such a system were available. The current residents of Port Pine Heights currently use septic tank waste disposal systems; however, the number of current residents is substantially less than the number of residents that Port Pine Heights is designed to accommodate. The disposal of sewage by septic tanks will result in the introduction in the canal waters of partially treated effluent through exchange with subsurface waters in the porous limestone substrata present in the area. To maintain the water quality at the required level, the waste effluent from the residential development must be prevented from entering into the canal. Because of the substantial difference in the level of development existing in Port Pine Heights currently and the potential level of development, the test data and the projections based upon that data do not give reasonable assurances that the increased pollutions attributable to the use of septic tanks would not violate water-quality standards.
Recommendation Until the Applicant makes a reasonable, affirmative showing that the long- term effect of the activity will not violate the water-quality standards, the application should be denied.

The Issue The ultimate issue is whether Celebrity Resorts, Inc., (Celebrity) is entitled to a permit to construct a wastewater treatment and reuse/disposal facility in Marion County, Florida.
Findings Of Fact Proposed Project Celebrity is seeking a DER permit to construct a 0.065 million gallon per day wastewater treatment and reuse/disposal facility to serve a proposed recreation vehicle (RV) park. The facility is to be located in northern Marion County on the southern border of Orange Lake, an Outstanding Florida Water. The RV park is to be located on 75 acres of land, and is to contain 372 RV and "park model" sites, four bath houses, a clubhouse, and an expanded boathouse. The sewage treatment plant (STP) and effluent disposal system, consisting of a spray irrigation system, are to be located on the southern end of the site, away from Orange Lake. There is a "break" in the watersheds of the Celebrity property caused by a ridge across the approximate center of the project site. The effect of this "break" is that approximately one-half of the property drains toward the lake while the approximate southerly half of the property drains into an independent depression creating a watershed separate from the lake. Some underground pipes for a sewage collection system were installed at the site without an appropriate DER permit. Celebrity stopped the installation upon notice from DER that a permit was required for such installation. The permit needed for the installation of the collection system pipes was not the permit for the sewage treatment project which is being considered in this proceeding. Celebrity was penalized for its collection system violation, which was resolved with a consent order. Sewage Treatment Plant (STP) The STP is an extended aeration plant. It is designed to meet secondary treatment standards (90% removal of BOD and suspended solids from raw sewage) and basic disinfection. This type of treatment plant is very reliable. All mechanical components have a 100% backup so if a pump or blower fails, another is available to operate. The STP is designed to be capable of treating the flow from this RV park. Additionally, the facility has a holding pond for treated sewage effluent that can store five days of flow. Furthermore, because the RV park is a transient facility, it is possible in an emergency to shut down the entire plant and have people leave. By its nature, this is much more convenient in an RV park that in a residential or commercial neighborhood. The holding pond is to be lined with a 60 millimeter high density polyethylene liner, so there should be no leakage to the ground or groundwater even if there is an accident in the STP causing release of untreated sewage into the holding pond. The STP is to be maintained five days a week and must be attended for three nonconsecutive visits a week by a Class D certified plant operator. The amount of dissolved/undissolved heavy metals in the effluent is typically not a problem in domestic sewage effluent such as from the proposed RV park. To the extent that trace amounts of metals will exist, the STP will remove some heavy metals from the effluent during the treatment process and entrain them in the sludge (which will be taken to appropriately licensed landfill). There is no possibility of effluent leaking or discharging from the plant to directly discharge to Orange Lake, even if the STP completely malfunctions. Although the proposed STP is not a highly sophisticated plant, reasonable assurances have been provided that the STP will comply with DER's requirements for secondary treatment and basic disinfection and proper operation. Effluent Disposal System (Spray Irrigation System) Phase I of the effluent disposal system (spray irrigation system) is 3.66 acres in size, with an additional 1.7 acres designated if Phase II is implemented. Approval under this permit authorizes only the 3.66 acres on Phase I. Numerous separate sprinkler heads will spray the treated effluent on the field. The heads can be separately controlled and shut down. The sprayfield is sited on the southwestern corner of the 75-acre site and is separated hydrologically from the Orange Lake drainage basin by the "break" referred to in Paragraph 4 above. Therefore, surface water drainage in the area of the sprayfield drains away from the lake and does not connect back to the lake. The permitted loading rate is 1.7 inches per week, or approximately 24,000 gallons per day at full capacity. This amount corresponds to only approximately 170% of natural rainfall, but is more evenly distributed and controlled. After uptake of nutrients by green plants and evaporation (evapo- transpiration), the average amount of treated effluent that will percolate below the "uptake zone" to the surficial aquifer (to the extent that such exists on the site) is 0.3 to 0.4 inches per week. The surficial water table in the area of the sprayfield generally flows to the north toward the lake, although the flow is not immediately direct toward the lake. The Floridan Aquifer (which is beneath the intermittent surficial water table) in the area of the sprayfield generally flows away from the lake to the south and southeast. There are four sinkholes on the 75-acre site, although none of these four sinkholes have been identified on the 3.66-acre sprayfield. The four sinkholes on the 75-acre site and the majority of sinkholes in the area are "subsidence sinkholes." These sinkholes do not result in an open void down to the limerock after the collapse forming the sinkhole, but instead continue to have unconsolidated material above the limerock, even though a depression forms on the surface. One of the sinkholes has standing water within it and could possibly represent a connection with the lake water table or the Floridan Aquifer, but that sinkhole is separated hydrologically from the sprayfield site by the "break" across the property. There will generally be a slight increase in hydrologic conductivity through a subsidence sinkhole, since the unconsolidated material on the surface remains and is loosened. In some cases there may be even less hydrologic transmissivity due to a "jamming up" of the unconsolidated material, and in some cases there may be an increase in transmissivity when the unconsolidated material falls into an even less consolidated state. A "lineament" may exist on the 75-acre site. A lineament is a fracture zone, which indicates an increase in ground water transmissivity, resulting in an increase in solution of limestone and therefore indicating a more likely location for sinkhole formation. If a sinkhole develops within the sprayfield and if the sinkhole results in an increased area of ground water transmissivity, it could be a conduit for treated effluent to reach the surficial aquifer or Floridan Aquifer. Sinkholes which may form on the site are subject to being repaired with impervious material which prevents their becoming routes of contamination to the aquifer. In addition, the loading rate of any single sinkhole that forms within the spray irrigation field is so light and so easily shut down that there is a high confidence rate that no new sinkhole will act as a conduit for even the small immediate discharge over the area of the new sink to reach the Floridan Aquifer. A spray irrigation effluent disposal system is appropriate for this area which is subject to sinkhole formation. Spray irrigation allows dispersal of the effluent over a large area as opposed to a percolation pond which concentrates in the percolation area and therefore increases the chance of sinkhole formation and the chance of larger amounts of effluent reaching the Floridan Aquifer if all the intervening safeguards should fail simultaneously. In addition, the repair of any sinkhole forming within the sprayfield is simplified by the ability to simply shut off the sprinkler head or heads affecting that sinkhole while repair is being effected. Permit conditions further limit excessive effluent application rates by limiting the amount of flow, prohibiting application during storm events, and requiring monitoring of the flow. Spray irrigation is a common method of effluent disposal which generally has fewer problems than use of percolation ponds. No evidence has been presented that discharge from the sprayfield will cause violations of groundwater quality standards or violations of surface water quality standards, including the Outstanding Florida Water requirements in Orange Lake. Reasonable assurance has been provided that the proposed effluent disposal system will not violate DER water quality standards or other applicable DER rules. Standing Petitioner Suto could be substantially affected by this proposed facility if it causes pollution to Orange Lake since she uses the lake for nature photography. Additionally, she resides to the southeast of the proposed sprayfield and has concerns over contaminated ground water reaching her property and affecting her drinking water. Petitioner Riley could be substantially affected by this proposed facility if there is pollution to the Floridan Aquifer since she lives southeast of the proposed facility and has two drinking water wells on this property. Additionally, Petitioner Riley is a user of Orange Lake and therefore could be substantially affected by the proposed facility if it impacts the lake. Petitioner Solomon could be substantially affected by the proposed project if the project impacts Orange Lake since Mr. Solomon earns his living on the lake as a commercial fisherman and bass fishing guide.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Department of Environmental Regulation enter a Final Order granting to Celebrity Resorts, Inc., a permit to construct a wastewater treatment facility and spray irrigation disposal system subject to the conditions set forth in the Intent to Issue.

The Issue Whether Respondent, John J. D'Hondt, as a licensed operator, should be disciplined for violations of Florida Administrative Code Rule 62-602.650(2), (4) and (4)(f).
Findings Of Fact Based upon the testimony and evidence received at the hearing, the following facts were established by clear and convincing evidence: Petitioner is the State agency vested with the responsibility of regulating Florida's air and water resources, administering Chapter 403, Florida Statutes (2006), and the rules promulgated in Florida Administrative Code Rule Chapter 62. Petitioner has the statutory authority to establish qualifications; examine and license drinking water and domestic wastewater treatment plant operators and to place an operator on probation; and issue, deny, revoke, or suspend an operator's license pursuant to its rules. Respondent is the owner, supplier of water, and licensed operator of the Double D Mobile Home Ranch's drinking water and domestic wastewater treatment plants located in Volusia County, Florida. He holds Certified Operator Drinking Water License No. 0000542 and Certified Operator Wastewater License No. 0006032. The Volusia County Health Department is a county health department that has been approved by Petitioner pursuant to Subsection 403.862(1)(c), Florida Statutes (2006), to enforce Chapter 403, Florida Statutes (2006), and the rules promulgated for the State's drinking water program for Volusia County. As a result of not having received Respondent's September 2004 MOR, by letter dated October 20, 2004, the Volusia County Health Department notified Respondent that MORs were to be submitted to the Volusia County Health Department by the tenth of the month following the month of operation. The November 2004 MOR was to have been submitted to the Volusia County Health Department by December 10, 2004. Respondent signed and dated the November 2004 MOR on December 12, 2004; it was received by the Volusia County Health Department on December 27, 2004. The December 2004 MOR was to have been submitted to the Volusia County Health Department by January 10, 2005. On February 4, 2005, Respondent was sent a late reporting violation letter stating that the December 2004 MOR had not been received. This letter again reminded Respondent that MORs were to be submitted within ten days after the month of operation. The December 2004 MOR was received on February 11, 2005. The April 2005 MOR was to have been submitted by May 10, 2005. Respondent signed and dated the April 2005 MOR on May 17, 2005. It was received on May 27, 2005. The September 2005 MOR was to have been submitted by October 10, 2005. It was received on October 18, 2005. The November 2005 MOR was to have been submitted by December 10, 2005. It was signed and dated December 14, 2005, and received on December 19, 2005. Respondent did not timely submit MORs for the months of November 2004, December 2004, April 2005, September 2005, and November 2005. In 2004, the Volusia County Health Department inspected the Double D Mobile Home Ranch's drinking water treatment plant and found that Respondent maintained a combined logbook for the drinking water and domestic wastewater treatment plants. Respondent was informed that he was required to keep a separate operation and maintenance logbook for each of the drinking water and domestic wastewater treatment plants. On August 10, 2004, Petitioner inspected the Double D Mobile Home Ranch's domestic wastewater treatment plant and found that there was a combined logbook for the drinking water and domestic wastewater treatment plants. Respondent was again informed that he was required to keep separate logbooks for each plant. A non-compliance letter dated October 12, 2004, and a copy of the August 10, 2004, inspection report were sent to Respondent informing him that he needed to separate his operation and maintenance logbook. In 2005, the Volusia County Health Department inspected the Double D Mobile Home Ranch's drinking water treatment plant and found that Respondent still maintained a combined logbook for the drinking water and domestic wastewater treatment plants. During the inspection, Respondent was again informed that he was required to keep a separate operation and maintenance logbook for the drinking water and domestic wastewater treatment plants. On June 15, 2005, Petitioner inspected the Double D Mobile Home Ranch's domestic wastewater treatment plant and again found that Respondent was keeping a combined logbook for the drinking water and domestic wastewater treatment plants. During this inspection, Respondent was again informed that he was required to keep separate logbooks. A non-compliance letter and a copy of the June 15, 2005, inspection report were sent to Respondent again informing him that he was required to maintain separate logbooks for the drinking water and domestic wastewater treatment plants. On February 13, 2006, the Volusia County Health Department inspected the Double D Mobile Home Ranch's drinking water treatment plant and found that Respondent still maintained a combined operation and maintenance logbook for the drinking water and domestic wastewater treatment plants. During this inspection, Respondent was again informed that he was required to maintain a separate logbook for each plant. Over the extended period reflected by the inspections cited in paragraphs 11 through 15, Respondent failed to maintain separate logbooks for the operation and maintenance of the Double D Mobile Home Ranch's drinking water and domestic wastewater treatment plants. On August 10, 2004, Petitioner inspected the Double D Mobile Home Ranch's domestic wastewater treatment plant and found that the logbook did not contain sufficient entries of the performance of preventative maintenance and repairs or request for repairs of equipment. During this inspection, Respondent was informed that he was required to keep adequate entries of preventative maintenance and repairs or request for repairs of equipment for the domestic wastewater treatment plant. A non-compliance letter and a copy of the August 10, 2004, inspection report were sent to Respondent informing him that he was required to maintain entries of the performance of preventative maintenance and repairs or request for repairs of equipment for the domestic wastewater treatment plant. On June 15, 2005, Petitioner inspected the Double D Mobile Home Ranch's domestic wastewater treatment plant and again found that Respondent was not keeping adequate entries of the performance of preventative maintenance or repairs for the domestic wastewater plant. During this inspection, Respondent was again informed that he was to keep such entries. A non-compliance letter and a copy of the June 15, 2005, inspection report were sent to Respondent informing him that he needed to maintain such entries for the domestic wastewater treatment plant. Photocopies of the combined logbook have essentially no entries for the performance of preventative maintenance or repairs or requests for repairs to a domestic wastewater treatment plant. Infrequent margin notes are not decipherable and do not differentiate between the two activities.
