Findings Of Fact This case involves the Department's attempt to purchase and utilize eight water quality data transmitter/display/logger units to measure parameters of pH, conductivity, DO (dissolved oxygen), temperature, depth, salinity, an option for oxygen reduction potential, and an option for ammonia measurement simultaneously in either fresh water or salt water for a period of up to 48 hours. The Department mailed ITB No. 93-03, entitled Water Quality Data Transmitter/Display/Data Logger Unit, on October 7, 1992. The term "parameter" refers to specific measurements such a pH, dissolved oxygen, conductivity, depth, and temperature, those measurements that were called for in the ITB. The term calibration refers to adjusting the measurements by a comparison to a standard. Calibration is performed to compensate for drift or shift in measurements, usually over a period of time. ITB No. 93-03 contained the following specifications for the desired equipment under "special Conditions and Specifications": Water Quality Data Transmitter/Sonde - for use in both fresh and saltwater with automatic temperature compensation. Include temperature, conductivity, dissolved oxygen, depth, and low ionic pH system. Must be able to calculate or determine salinity and DO percent saturation. Must have option of adding additional probes, e.g. ORP and Ammonia. - 8 units. Water Resistant Digital Display/Data Logger Must be programmable for unattended data measurements for all parameters in item no. 1 above at various intervals (e.g. every 15, 30, 60 minute) and have the capability of logging all such data. - 8 units. Calibration/Maintenance Kits - Calibration for all parameters in item 1 must be simple, requiring 5 minutes or less for each parameter. - 8 units. Stirrer Units (if needed) - 8 units. PC compatible Software and Cable for data down loading - 8 units. Sonde to Logger/Display Unit Cable - at least 50 feet. - 8 units. Unattended Monitoring - Must be able to log and maintain water quality data file for a sampling frequency of 15 minute intervals over at least a 48 hour period while in an unattended mode of operation - 8 units. Field Carrying Case for Sonde and Display/Logger Unit - 8 units. User Manuals - 8 Units. Probe weights (if needed) - 8 units. ITB No. 93-03 specified the following warranty and delivery requirement: Must carry 2-year warranty on Sonde, Display/Logger Units, Stirrers, and Cables. Warranty service must be provided within two weeks of notification or, if extended repair period is required, then loaner units must be made available at no cost to DER during the warranty period. Delivery must be within 45 days of bid award. Petitioner Solomat's bid of $50,086.32 was the lowest when bids were opened on October 23, 1992. The company's written equipment specifications provided by the Petitioner to the Department were similar or superior to the written specifications provided with the competing bid responses. They were submitted in compliance with "General Condition" No. 7, page 1 of the ITB, which required submission of full specifications. Dr. Wayne Magley, on behalf of the Department, requested that Petitioner demonstrate the equipment it was offering in its bid response because the Department was not familiar with the Petitioner nor its equipment. After the bid opening, and before award in November 1992, Petitioner demonstrated its existing MPM4803 production unit for the Department in Florida, along with the 803PS sonde. A sonde is a multiparameter probe. The 803PS sonde was capable of being plugged into the existing MPM4803, and the WP4007 and WP803 data logger units then under development by Solomat. Petitioner agreed to modify its software for the MPM4803 to add the ability to read out in milligrams per liter (MG/L), a capability not mentioned in the ITB specifications or in Solomat's company specifications. This software modification contributed to the Department's subsequent calibration troubles because, according to Mr. Stonier, the modification of the unit software rendered Solomat's "how to" manual less accurate, detailed, and specific than it would have been for the unmodified software. The Petitioner amended its bid offering by letter dated November 5, 1992, to include, in addition to its October 20, 1992 bid response, the following: Stainless Steel Relief Cables with each unit Display D.O. readings in MG/L. A day of On-Site training from a Solomat factory representative A day of training at each local site from Geometrics. The ITB had only called for a water resistent product, but during this same pre-contract award period, Department personnel expressed a need to hose off the equipment. Hosing off the equipment would require a waterproof unit, so Petitioner offered the option to upgrade to new instruments slated for development and sale in April or May of 1993. In so offering, Solomat's representative described to Department personnel a WP4007 unit then under development. Solomat also had its WP803 unit under development. The WP803 also was intended to be developed to be waterproof. The WP803 was not part of Petitioner's additional offers to the Department in November 1992. Although Mr. Stonier asserted at formal hearing that Solomat's November 1992 upgrade offer was not integral to the finalized November 1992 bid award, he conceded that the Solomat offer was, "something Solomat was obliged to provide." In fact, this offer was reduced to writing. In response to the Department's concerns about hosing off the units, the Petitioner also promised a latex boot to protect the probe on the MPM4803 unit. This offer also was reduced to writing. The Petitioner further amended its bid response by letter dated November 10, 1992, to include, in addition to its October 20, 1992 bid offering and its November 5, 1992 enlargement of that offer, the following: Both versions of the weighting bracket will be provided with each unit. Two year warranty will cover any damage due to immersion or intrusion by salt air. Bottom latex boot will be supplied in addition to latex cover which you saw displayed today. A wrist strap will accompany each unit. Any further software (CS4) or Eprom updates will be available at no charge. SOLOMAT will extend the option to upgrade any or all of the instruments, with our new, fully waterproof version WP4007, within the next year at no charge. We will ship demo MPM 4803, fully preprogrammed, to be received by D.E.R. prior to November 18, 1992. Petitioner knew via the original ITB specifications and by the further discussions that took place in November 1992 after the bid opening and prior to the final award and purchase order that the Department was concerned about the ruggedness, watertightness, and use of the eight instruments in the field for extended periods in various conditions and types of water. No. 1 and No. 7 of the ITB "Special Conditions" specifications clearly stated that the Department wanted to leave the units on site for 48 hours in varying types of water. At formal hearing, Mr. Stonier admitted he knew in November 1992 that was what the Department wanted to do even if the ITB were confusing. The Petitioner knew that the Department would be utilizing the water quality monitoring equipment under diverse conditions in the field because Mr. Stonier's November 12, 1992 letter to the Department provided as follows: The D.E.R.'s application includes the tough everyday use in varied environments that demands the ruggedness and reliability that the Solomat instruments have been designed and are each tested for. Mr. Stonier testified at formal hearing that it was understood in November 1992 . . that the units were going to be carried out on site into various types of measurement situations, . . . and that the probes would be -- the 803PS sonde would be submerged, and samples would be recorded. And these instruments are certainly designed to do that. in fact, they're designed where they can be left out on-site for longer periods of time. The Department accepted the Petitioner's October 20, 1992 bid as amended by its November 5 and 10, 1992 letters, and in reliance on those letters. Although the ITB contained no definition of "accuracy", the Department's acceptance of Petitioner's bid also included reliance on Solomat's equipment specifications regarding equipment accuracy submitted by Petitioner in its response to "General Condition" No. 7, page 1 of the ITB. The bid acceptance and subsequent purchase order occurred on or about November 20, 1992. The purchase order is not in evidence. In January 1993, Petitioner delivered eight MPM4803 units and eight 803PS sonde units to the Department in response to the bid award/purchase order. This model was equipped with a latex boot, but the Department complained about the waterproof ability of the boots, and Petitioner promised to provide wider latex boots. Petitioner's training representative provided one day of training in Tallahassee and one day of training in Orlando in early February, 1993. Petitioner's training representative encountered difficulty in demonstrating how to calibrate the equipment at the February 1993 Tallahassee training session which he was unable to resolve prior to calling Petitioner's U.S. headquarters for technical assistance. Beginning in early February 1993, Department personnel repeatedly encountered problems in calibrating the Petitioner's equipment. Calibration problems were encountered in trying to follow the manuals provided by the Petitioner despite some additional written instructions beyond the original faulty manual (see Finding of Fact 11) and despite oral instructions by telephone. There also were continuing problems with the pH sensor, with conductivity, and with DO (dissolved oxygen). Beginning in February 1993, Department personnel repeatedly encountered problems with Petitioner's equipment's inability to stay calibrated and to take accurate measurements resulting from excessive drift. Solomat employees perceived the Department users as unsophisticated and slow to understand how to use the Solomat equipment, and as preferring the earlier models of similar units with which they were more familiar and which had been developed by competitive vendors. Indeed, some documented user errors included Department personnel failing to remove probe guards on sensors. Some OC3 dissolved oxygen sensors in the 803PS sonde had to be replaced by Solomat due to user error in installing them without the 0-ring so that water could seep in and damage the equipment or with two 0-rings so that there was no contact between the electrode and the probe sonde. However, these types of human error did not significantly affect valid tests showing calibration drift and accuracy reading problems. It is noted that P-5 (Loxahatchee notes), an August 24, 1993 28 day "short informal report" relied upon by Petitioner to show that some persistant, open-minded Department users could learn to correctly calibrate the MPM4803 data loggers/803PS sondes and that good data could be gathered over more than 48 hours, contains on its first page the comment, "Stabilities were very good except DO; it is unclear whether this was due to probe response drift or improper calibration by Solomat representatives." Department personnel tracked their problems with the Petitioner's MPM4803 equipment's failure to take accurate measurements by sampling at field sites which have been consistently tested by Department personnel with other equipment over a period of years so that they had a background of data for comparison for any given parameter. When they were unable to account for significant drifts of calibration and even negative readings in some parameters on Petitioner's products, Department personnel then used other vendors' water quality monitoring equipment to confirm that the Petitioner's equipment was not giving consistently accurate measurements. Although Petitioner's witnesses testified concerning their perception that such methods of comparison lacked accuracy and fairness, they offered no better field tests as an alternative. Petitioner's concerns mostly centered around other vendor's meters also sometimes registering outside ITB or company specifications. However, in fact, the Department was making some of its assessments based upon calibration and post-calibration readings on the same Solomat meter each time. In light of the testimony of John Kent Edwards that in his District, he personally calibrated the Petitioner's units every morning in the laboratory before they went out in the field and that careful post calibration procedures on the same meters still demonstrated significant drift; the testimony of Mr. Edwards and Louis They that standard calibration solution or calibration solutions prepared fresh by a chemist were used in calibrating Petitioner's units to eliminate variables of that sort; the admission by Don Roos to Department personnel in July 1993 that it could take five minutes to stabilize DO on the low end and on the high end (see Finding of Fact 36); the acknowledgement by Peter Ebersold that it is possible that DO and pH drift would violate ITB specifications and Petitioner's own equipment specifications over more than 24 hours in dirty water; Dr. Saffel's uncontradicted testimony that the calibration on all Petitioner's units provided to the Department were written only for generic water, not water as bioactive as some of Florida's water, and that Petitioner's units' long term stability of calibration depends very strongly on the purity of the water being measured; and Wayne Magley's testimony that a subsequent Winkler Titration test in the laboratory verified the other vendors' scores but not Petitioner's scores while showing that Petitioner's units were working correctly, and that statistical correlations of all the meters were done, it is found that the Department's testing procedure is probative and persuasive that the MPM4803 units were not meeting certain specifications encompassed in the bid award/purchase order. The Petitioner's assertion that low ionization cables threw off all calculations is in the nature of a nonsequitur, since this type of cable was agreed upon in the amended bid responses, became part of the parties' contract, and Petitioner was required to provide workable units under that agreement. Petitioner's assertion that the conversion of readings to MG/L was the problem falls in the same category. During 1993, both parties made repeated good-faith attempts to resolve the calibration and instrument accuracy problems, with the Department informally telephoning Petitioner for assistance and sharing information among the Department's Tallahassee office and district personnel. By a June 9, 1993 letter, the Department provided Petitioner its data showing its employees were not able to get consistent, reasonable readings with the Solomat units. In June 1993, Wayne Magley, on behalf of the Department, asked the Petitioner to provide additional on-site assistance because Department personnel were still unable to resolve problems with calibrating and using Petitioner's equipment despite Petitioner rendering helpful technical advice when called by Department personnel. Dr. Magley specifically asked for Don Roos because of Mr. Roos' history of being extremely knowledgeable about the equipment and rendering helpful technical advice when called. In July 1993, Don Roos and Peter Ebersold came to Florida to provide assistance at the Department headquarters in Tallahassee and Orlando District office. During the Tallahassee visit, Mr. Roos admitted that it could take up to five minutes for DO to stabilize before it could be calibrated for low end and five minutes for DO to stabilize for high end, for a total time in excess of 10 minutes for one parameter. This calibration time violates the Department's bid specification that each parameter must be calculated in five minutes or less. Misters Roos and Ebersold observed Department staff calibrating the MPM4803 with the 803PS sonde during their July 1993 visit to Tallahassee and did not have any criticism of the Department staff's calibration process. Petitioner diagnosed a problem with its MPM4803 units as being that some Department users were inadvertently recalibrating temperature and misinterpreting "error" message prompts, thus throwing all the readings off. Therefore, Solomat made a change to eliminate "temperature" from the recalibration cycle and changed the Eproms on the Department's units to simplify the procedure. Despite trying to get the wider latex boots for the MPM4803 units until July 1993, Petitioner was unable to obtain wider latex boots and at that point gave up trying to get the required improved boots for the MPM4803 units, in anticipation of being able to upgrade the Department to newer units. The Petitioner reiterated in correspondence as late as August 3, 1993 that the Department would be receiving an upgrade from the MPM4803 to the WP4007 units, stating, "[t]he exchange of your MPM4803s with the new WP4007 waterproof dataloggers will occur near the end of the year." Dr. Saffell testified that the Department was promised an upgrade on his authority. By a November 15, 1993 letter, the Department reported to Petitioner that most of its employees still could not calibrate for each parameter within the five minutes or less as required by the ITB specifications and still had difficulty getting consistent readings. The Department wanted to return the units for refund. By a December 7, 1995 letter, the Department notified Petitioner that it intended to find Petitioner in default of the bid contract including failing to provide the promised upgraded units in any timely fashion despite Petitioner's promise to do so within a year of its November 10, 1992 bid amendment and because the Petitioner's equipment could not be consistently calibrated in five minutes or less for each parameter as required by the bid specifications. The Petitioner also had never supplied the latex boot as agreed. It is clear that as of the December 7, 1993 letter, Petitioner was in default on the foregoing three elements of its contract with the Department. By letter dated December 13, 1993, Petitioner notified the Department that it still wished to provide the instrument upgrade. In this letter, Petitioner unilaterally changed the model it was going to provide from the WP4007 to the WP803, on its own assessment that the WP4007 had too many options and a more user friendly unit would be less confusing to Department users. The WP4007 features which are not on the WP803s were not part of the original ITB specifications. The WP803, like the WP4007, was intended to be waterproof. Solomat's specifications for the WP803 were intended to exceed those of other vendors for comparable machinery. Despite Solomat's best intentions to have both the WP4007 and the WP803 models fully developed and ready for the market in April or May of 1993, neither the WP4007 nor the WP803 was released in the United States until February or March 1994. By letter dated December 21, 1993, the Department gave Petitioner until February 1, 1994, to correct its failed performance under the contract by supplying eight replacement units that met the specifications agreed upon back in November 1992. No mention was made of what model unit would be necessary, however the Petitioner was notified that the replacement units had to be provided to the Department for testing and that the units had to be acceptable to the Department after testing by February 1, 1994 in order for Petitioner to avoid being found in default of the bid contract. The Department did not, in this letter, or at any other time, specifically agree to accept the WP803 upgrade instead of the promised WP4007 upgrade, but specified that a failure to supply eight upgraded units and have them timely accepted by the agency would result in default. Petitioner responded that it would provide two prototypes or preproduction units to test in January and try to meet the Department's February 1, 1994 deadline for delivery of eight upgraded units. The Department allowed Solomat until February 15, 1994 to exchange eight satisfactory upgraded units for the eight MPM4803s originally supplied. Petitioner delivered two WP803 preproduction units and provided some training in January 1994. WP4007 preproduction units could have been provided but were not. Because development had lagged behind marketing, Petitioner had inventory of neither WP803 nor WP4007 production units. The Department conducted testing, some of which could be considered limited field use, on January 18-20, 1994 on the prototype or preproduction WP803 units with Petitioner's representatives present. Petitioner's representatives did not criticize Department personnel's calibration procedures. On January 28, 1994, the Department provided the Petitioner a written summary of its findings as a result of the testing which included a four-point conclusion that the new units did not meet bid specifications. Petitioner's witness conceded the following: The circuit boards on the preproduction WP803 units tested in January 1994 had been assembled by hand. The internal programming on the Eprom was not fully debugged. There were problems with the conductivity linearizations. Petitioner attempted to interface those instruments with the 803PS sondes the Department already possessed and the modifications did not work. Petitioner did not intend these prototype WP803s to be used in the field because, among the foregoing problems, they were not fully waterproof. Petitioner's review of the Department's test data in February 1994 on the prototypes convinced the company that there were problems that went beyond mere user problems. Some parameters were acceptable but results were not reliable for all parameters. The testimony of John Kent Edwards, Louis They, and Wayne Magley together with Petitioner's assessment is sufficient to establish that despite a fair test, calibration drift for Petitioner's preproduction WP803 units tested on January 18-20, 1994 failed quality assurance levels and did not meet certain specifications of the contract. The Department eventually extended the February 1, 1994 deadline until February 21, 1994. The Department conducted additional testing on the WP803 production units supplied by the Petitioner prior to February 21, 1994. Wayne Magley set up and calibrated three of the production units received. One machine had an immediate hardware failure. Over a week, he did a series of calibrations and post-calibrations in the laboratory and one field trip. Despite employing calibration methodology to give Petitioner the benefit of the doubt and even accounting for low ionic strengths, the "five minutes for calibration of each parameter" specification could not be met. Problems with accurate readings remained even when Petitioner's instruments were tested against each other. Department testing on the WP803 production units demonstrated that they also failed to meet either the ITB specifications or the company specifications provided by the Petitioner as part of its bid. By a March 3, 1994 letter, the Department notified Petitioner it was declaring a default, pursuant to Rule 60A-1.006 (3) F.A.C. By mid-February, Petitioner had not supplied more than four production level WP803s. The Department instructed Solomat not to ship any more units because Department tests on the first four made the Department not want to progress further. Petitioner did not send the additional WP803 production units. The Department ended up with four MPM4803 production units, four WP803 production units and four 803PS sondes. Solomat has four 803PS sondes at its Connecticut office marked, "DEP property." In August 1994, Petitioner provided its production level WP803 data logger and 803PS sonde to U.S. Testing Labs which performed an independent evaluation to determine if the problems that the Department had experienced were with the units or with the users. Daniel Cooke, Ph.D., was in charge of the test. He, like the Department, had some initial start up difficulty, including learning how to calibrate with oral instructions over the telephone beyond the printed December 1993 instruction manual; a loose connection that Petitioner had to repair; and conductivity adjustments that Solomat had to make. As a result, he aborted the first test on his own and aborted the second try at a test at the request of Solomat. He found he was able to calibrate with the June 1994 instruction manual Petitioner created after the Department had claimed a default. His test results also showed that: 1) high DO was outside of specification throughout the test; 2) conductivity was outside of specification throughout the test; 3) salinity was outside of specification throughout the test; and 4) all parameters were outside of Petitioner's specifications at times during the testing. Petitioner's witness conceded that there could be some drift over the period of a week in the field, some small drift over two hours even in the lab calibrations and DO and pH drift could violate the ITB's "48 hours" specification, dependent upon the pollution of the water in the field. A few months before formal hearing, Petitioner revised its own company specifications to define more realistic tolerances under actual field conditions as 24 hours and two weeks after calibration. The Department represented that it has not yet gone to the next bidder or established a timetable and assumed any costs of reletting the ITB, as contemplated by Rule 60A-1.006(3) F.A.C., because it has no money to do so. Accordingly, there is no evidence of cost of reprocurement which the Department seeks to assess against Solomat (TR-12-13)
Recommendation Upon the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the Department of Environmental Protection enter a final order that (1) determines Petitioner to be in default of its contract; (2) orders Petitioner to reimburse the Department $50,086.32 as refunded contract monies, without any additional cover costs; (3) orders Petitioner to pay to the Department, on or before the date payment of the contract monies is made by Petitioner, an amount equal to the actual cost of contracting with the next lowest bidder or the cost of reprocurement or the costs attendant upon replacement purchase on the open market in an amount either stipulated between the parties or as estimated upon past agency experience in letting the original bid/contract; (4) provides for the return of all equipment to Petitioner upon satisfaction of the requirements of paragraphs 2-3; and (5) provides for the removal of the agency decertification upon the satisfaction of the requirements of paragraphs 2-3.

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

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.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a final order be entered granting Seanic's application for an operating permit for its domestic wastewater treatment facility but denying Seanic's Motion for Attorney's Fees and Costs.

The Issue The issue in this case is whether the Department of Environmental Protection (DEP) should issue a permit to Out of Bounds, Inc. (Out of Bounds, or applicant), to construct, operate, and close a construction and demolition debris disposal facility (C&D facility) in Hernando County.
Findings Of Fact On September 8, 2008, Out of Bounds applied to DEP for a permit to construct, operate, and close an unlined C&D facility on 26 acres located at 29251 Wildlife Lane, Brooksville, Hernando County, Florida, to be known as the Croom C&D Debris Landfill and Recycling Facility. There were four requests by DEP for additional information, which was provided, and the application was complete on September 3, 2009. In 1994, a previous owner of the property was issued a permit to construct, operate, and close an unlined C&D facility on the property. That owner did not proceed with construction, and the permit expired in 1999. The Out of Bounds application was for a new permit, not for the renewal of an existing permit. Robert McCune owns property adjacent to the proposed C&D facility. He and his wife reside on the property, keep horses in stables on the property, and use the property for horseback riding business, which includes hosting public horseback riding events. Hernando SSK was formed by David Belcher and one or more others to continue the business being operated by Paige Cool when she died during this proceeding. The business is conducted on ten acres of property Cool owned approximately one mile west of the proposed C&D facility. Belcher is one of two co-personal representatives of Cool’s estate. Belcher and his wife hold a mortgage on the property. When the estate is finalized, the Belchers plan to assign their mortgage to Hernando SSK. It is not clear who will own the property after the estate is finalized, or how Hernando SSK will be authorized to continue the business on the property. Western pleasure and trail-riding horses are boarded on the Cool property, which is known as At Home Acres. The business also has access to 20 adjoining acres to the east, which are used for grazing. Access to the horseback riding trails in the Withlacoochee State Forest is conveniently located just across Wildlife Lane from the property, to the north. A manager resides in a double-wide trailer on the property, and another trailer and a barn to the east of it are leased out. There is a potable water well on the property, which is the source of drinking water for the manager and lessees. Well Setback In the application process, Out of Bounds disclosed two potable water wells within 500 feet of the proposed landfill disposal area. The application provided that those wells would be converted to non-potable use. Out of Bounds did not disclose the existence of a third potable water well, on property owned by Daniel Knox, which is within 500 feet of the proposed landfill disposal area. When the Knox well was brought to the attention of DEP, Out of Bounds admitted that the well was permitted for potable use but took the position that it was not for potable use because it was not in use, was not connected to a source of electricity, and appeared to be abandoned. Daniel Knox and his brother, Robert Knox, had the Knox well dug and permitted in 1979 in anticipation of using it as the source of potable water for a residence to be built on the property for their parents and sister. The Knoxes have not yet built a residence on the property, but it still is their intention to do so and to use the well as the source of potable water. Since its construction, the well had been maintained and operated periodically using a gasoline-powered generator so that it will be ready for use when needed. During the application process, Out of Bounds also did not disclose the existence of a fourth potable water well within 500 feet of the proposed landfill disposal area on property once owned by Larry Fannin and now owned by his daughter and son-in- law, Robert McCune. The McCune well was permitted and installed in mid-2005 while the sale of the land from Fannin to the McCunes was pending. The intended purpose of the well was to provide potable water for the use of the McCunes when they started to reside on the property. Despite this intent, and unbeknownst to the McCunes, Fannin had the well permitted as an irrigation well. In mid-2008, the McCunes began to reside on their property. At first, they resided in a mobile home. They ran pipes from the well to the mobile home to provide drinking water. Eventually, later in 2008, they began construction of a residence on the property and ran pipes from the well to the house to provide drinking water to the house. The well was being used for drinking water before the Out of Bounds application was complete. (They also use water from the well from time to time for irrigation purposes--i.e., when they host horseback-riding events on weekends, they truck water from the well to their horseback-riding arena to apply to the ground to control dust.) Groundwater flows from the disposal area of the proposed landfill to the west and southwest. The Knox and McCune wells are down-gradient of the groundwater flow from the proposed disposal area. Out of Bounds represented at the hearing that it would accept a permit condition that no C&D debris, but only clean debris, would be disposed within 500 feet of the Knox and McCune wells. See Fla. Admin. Code R. 62-701.200(15)-(16) and (24). However, there was no evidence of new designs, plans, or operations that would be used to meet such a permit condition. Liner and Leachate Collection Existing unlined C&D facilities in the Southwest District report various parameters that exceed groundwater quality standards and criteria. These include arsenic, benzene, iron, aluminum, nitrate, ammonia, vinyl chloride, methylene chloride, 3- and 4-methyl phenols, sulfate, and total dissolved solids (TDS). Arsenic and benzene are primary (health-based) groundwater quality standards. The others are secondary standards that relate to taste, odor, and aesthetics. The likely source of the reported arsenic violations in the Southwest District is wood treated with chromate copper arsenate (CCA). See Fla. Admin. Code R. 62-701.200(11). Out of Bounds proposes to not accept CCA-treated wood and to use a trained “spotter” to exclude CCA-treated wood from the landfill. This is an appropriate measure to prevent arsenic violations, and is now required for C&D facilities. See Fla. Admin. Code R. 62-701.730(7)(d), (8), and (20). It was not clear from the evidence whether the C&D facilities in the Southwest District with arsenic violations accepted CCA-treated wood. Even if they did, the operational plan proposed by Out of Bounds to exclude CCA-treated wood and to use a trained spotter is not a guarantee that no CCA-treated wood will enter the landfill. A C&D facility would not be expected to dispose of material that would result in benzene contamination. The reported benzene violations suggest that unauthorized material contaminated with benzene nonetheless makes its way into C&D facilities in the Southwest District. The evidence was not clear whether a trained spotter was used at those facilities. Whether or not a spotter was used at those facilities, having a trained spotter would not guarantee that no benzene-contaminated material will enter the landfill proposed by Out of Bounds. Out of Bounds suggested that ammonia violations result from C&D facilities accepting yard trash. However, there was no evidence of a connection between acceptance of yard trash and ammonia violations. The operational plan proposed by Out of Bounds to “cover as you go” is the accepted best practice to control hydrogen sulfide odor, which comes from wet drywall. Out of Bounds suggested that its cover plan would prevent any sulfate violations, but there was no evidence to prove it. There was no evidence as to whether the C&D facility proposed by Out of Bounds would be substantially different from the other existing C&D facilities in DEP’s Southwest District. Absent such evidence, Out of Bounds did not provide reasonable assurances that its proposed facility would not cause groundwater quality violations. The site for the C&D facility proposed by Out of Bounds is internally drained. There are no surface waters onsite or within a mile of the site. There was no evidence of a surficial aquifer above the Floridan aquifer. Rainfall entering the Out of Bounds property migrates downward into the Floridan aquifer. Once in the aquifer, there is a horizontal component of groundwater water flow in a generally southwest direction, towards the Knox and McCune wells. Contaminated leachate from the proposed C&D facility would migrate with the groundwater. Out of Bounds suggests that a thick clay layer under the site of its proposed facility would prevent the downward migration of groundwater into the Floridan aquifer. There are several reasons why the clay layer does not provide the reasonable assurance of a liner that contamination from the proposed landfill would not reach the Floridan aquifer. Clay is much more permeable than a geomembrane meeting DEP’s specifications for use as a liner. The clay on the proposed site is on the order of at least a thousand times more permeable. (Out of Bounds appeared to confuse the permeability of such a geomembrane with the allowable permeability of the geosynthetic clay layer or compacted clay layer underlying the geomembrane. Cf. Fla. Admin. Code R. 62-701.730(4)(f).) In the application process, Out of Bounds relied on the clay layer for purposes of sinkhole prevention and mitigation, not for reasonable assurance that no liner was needed. The limestone formation underlying the site is highly variable, with numerous pinnacles; for that reason, the thickness of the clay layer also is highly variable, making it difficult to excavate the proposed landfill with complete assurance that the clay layer would not be penetrated. To provide reasonable assurance for purposes of sinkhole prevention and mitigation, Out of Bounds proposed to leave or create a clay layer at least six feet thick underlying the bottom of the proposed landfill. Because the site is in an area of high recharge to the Floridan aquifer and drains entirely internally, the clay layer alone does not provide reasonable assurance that there will be no downward migration of contaminated groundwater to the Floridan aquifer. Reasonable assurance requires a liner and leachate collection system.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that DEP deny the application for a C&D facility made by Out of Bounds.

Findings Of Fact South of the intersection of Blue Angel Parkway and Gulf Beach Highway in southwest Escambia County lies the wooded, 69-acre tract, designated "Site F," onto which ECUA proposes to dispose up to three million gallons of wastewater a day. Petitioner Westerman operates a marina nearby. The individual intervenors own houses in the vicinity as, apparently, do other members of the intervening association. A state agency with wide ranging environmental responsibilities, DER permits construction of wastewater treatment facilities in conformity with its rules. Sewage disposal is one of several utility services ECUA provides residents of Escambia County. A Trip to the Beach Under orders from DER and the Environmental Protection Agency (EPA) to cease discharging directly into Bayou Chico ("a very impacted body of water ... [with] very difficult problems" T. 101), ECUA proposes to build a pumping facility and install enough 24-inch pipe to enable it to send effluent from its wastewater treatment plant in Warrington to Site F, for "rapid rate" land application. Upgraded since DER and EPA forbade direct discharges into Bayou Chico, the Warrington plant now employs advanced treatment techniques to remove most phosphorous and nitrogen from its effluent. Nevertheless, in order to mollify regulators, ECUA has plans to ship the effluent through some seven miles of pipe to Site F. In the opinion of its executive director, ECUA is "an easy target . . . . Whether it's practical or fair is really not the question." Id. He feels, "cost is not a factor" (T. 102) that the regulatory authorities have taken into account. Sandy Soils Site F straddles a coastal ridge, vegetated dunes that separate Garcon Swamp from Big Lagoon. Elevations vary from 29 feet above mean sea level at the crest of the ridge to nine feet above mean sea level in the swale that traverses the property. Highly permeable surficial sand extends to depths ranging between 20 and 35 feet below grade. Under the surficial sand, a layer of silty sand, extending down 55 to 60 feet, overlies another layer of very clean sand, much denser than the surficial sand. At depths of 90 to 110 feet, a clay aquiclude undergirds these sandy strata. Using field and laboratory test results, experts put the average hydraulic conductivity of the surficial sands at 35 feet per day, of the silty middle sand layer at 10 to 15 feet per day, and of the clean but dense sands on top of the clay at 5 to 10 feet per day. In addition to laboratory results, two pump tests support these conclusions. Results of two other pump tests indicating hydraulic conductivity of 4.7 and 5.0 feet per day were dismissed as unreliable. Sand caving in compromised at least one of these tests. As far as the record reveals, no bench-scale or pilot-scale hydraulic testing took place. According to DER's Mr. Reinning, there was "more soil testing on this site than [he had] seen on any other permit event." T.II. 217. Although the soils on the site are "relatively uniform," (T.II. 212) no layer of sand is perfectly uniform. Mr. Jacobs, one of ECUA's consultants, testified that a boring on one of the proposed pond sites revealed a one-foot layer of sand and organics with a vertical hydraulic conductivity of one foot per day. T.I. 245. Perhaps Mr. Jacobs was referring to boring B-2, which, according to the log, reflects a two-foot interval of peat and decaying wood, at a depth of slightly more than 13 feet. ECUA's Exhibit 2. No other boring gave evidence of this layer. The nearest bore hole to B-2 was more than 200 feet away. Expert testimony that the borings did not indicate an "extensive pocket," and gave no reason to fear a "per(c)hed water table," (T.II. 214) was not controverted. Construction Plans ECUA proposes to construct 16 percolation ponds or cells on Site F. Seven pairs of cells would be terraced on a north-south axis, with an eighth, noncontiguous pair at an angle in the southwestern portion of the property. Cell bottoms, at elevations ranging between 16 and 27 feet above mean sea level, would have a surface area aggregating some 23 acres (1,027,900 square feet.) ECUA would erect a perimeter fence and install warning signs. Except for valves, "no mechanical equipment [would be) involved in the disposal site," T.123, nor are "bright lights," id. planned. Water flowing into percolation ponds does not create an aerosol. Odors are not foreseen. Encircling each infiltration basin, berms three to three and a half feet higher than the cell bottoms would contain effluent and deflect sheet flow. Except for rain falling directly into the cells, stormwater would not reach the percolation cells. Chances that effluent augmented by rainfall would overflow the berms are remote. A 100-year, 24-hour return storm would not interrupt operation of the facility. No percolation pond site lies within the 100-year flood plain. No percolation basin is to be located within 500 feet of a potable water supply well or class I or class II surface water; or closer than 100 feet to the boundary of the property. Situated within some 20 acres of wetlands, a brackish pond lies about 1,000 feet from the nearest cell planned, between Site F and Big Lagoon into which the pond opens. At the nearest point, Big Lagoon itself comes within 1200 feet of a planned percolation cell. A swale or slough bridged by Blue Angel Parkway runs southwesterly north and west of the main phalanx of percolation ponds ECUA proposes, then turns a corner and runs southeasterly, separating the two cells proposed for the southwest portion of the property from the others. The nearest percolation pond is to be built about 100 feet from wetlands associated with the swale. Loading Rates ECUA plans to direct wastewater into half the cells one week and the remainder the next, alternating like the squares on a chessboard. The exact cycle is not a condition of the construction permit, however, and computer modelers assumed loading cycles consisting of two two-day periods. As applied to the total bottom area of percolation cells, the average daily loading rate for three million gallons a day (mgd) would amount to 2.91 gallons per square foot. Because half the ponds would be resting at any given time, ponds receiving effluent would experience inflow at an average rate of 5.82 gallons per square foot. In deciding the length of the loading cycle, as "the soil gets lower in permeability you have to really stretch your time for loading out, because it takes the water much longer to get out of the loading area." T.I. 188. But, with respect to the long-term capacity of the system, "the period of loading and resting . . . really doesn't significantly affect . . . how the site is expected to perform." T.II. 222. In the absence of bench-scale or pilot-scale tests heretofore, the applicant "intend[s] to load test this site, because just for the various concerns, because it is a big site." T.I. 189. Groundwater Effects Class G-II groundwater under the site now flows generally southerly toward the brackish pond and Big Lagoon. An expert put the rate of flow under the site at .22 feet per day, but concluded that the rate increased to approximately a half foot a day between Site F and Big Lagoon. As far as is known, groundwater under the sites proposed for the infiltration ponds rises no closer to the surface than six to nine feet, even under wet conditions, although the evidence by no means conclusively established that it would never rise higher. Some groundwater emerges in the swale during wet periods, and flows in the swale as far as the brackish pond, to which other groundwater makes regular, direct contribution. At the edge of the lagoon, further out in the lagoon and possibly in the Gulf of Mexico, still other groundwater comes up as springs. At least initially, the sandy soils would accept effluent readily. Until and unless actual experience showed that the facility could handle the three mgd for which it is designed, the plan is to dispose of no more than 2.5 million gallons of effluent a day. Before equilibrium is attained, ongoing disposal of effluent would gradually raise the level of groundwater under the site, inducing, on the preexisting, sloping surface of ambient groundwater, a mound, on which 16 smaller mounds (corresponding to the loading nozzles discharging wastewater into the percolation ponds) would superimpose themselves, half swelling, like so many goose eggs, half subsiding, at any given time. Adding effluent should not materially alter the ultimate direction of flow. For the most part, even groundwater flowing in other directions off the mounds induced under the site would eventually turn south toward the lagoon. But a steeper gradient should speed up the flow. Percolating effluent would increase the volume not only of seepage into the swale but also of subterranean flow reaching both the brackish pond and the lagoon. Increased seepage upslope from the slough would flow down into the swale, along the stream bed, and into the brackish pond. Monitoring As modified at hearing, ECUA's monitoring plan contemplates eight wells and four surface water monitoring points from which water samples would be periodically taken for analysis, to determine levels of nitrogen, phosphorous and other chemical and biological constituents of concern. Once the facility began operating, no well would yield "background" samples uninfluenced by the effluent. T. I. 221. The wells are all to be located on ECUA property and, therefore, close enough to the percolation ponds to receive ground water flows radiating from the mounds adding the effluent would induce. Final Destination Effluent emerging in seepage, perhaps as much as 75 percent of the total (T. III. 47), could reach Big Lagoon, by way of the swale and the brackish pond, soon after regaining the surface of the land. Wetland vegetation would filter such flows, already diluted underground and sometimes by stormwater runoff, on their way to the lagoon. Effluent that mixed with groundwater traveling to Big Lagoon underground would not show up in the lagoon for months or years. But when it arrived, much diluted and after such attenuation of pollutants as the largely inorganic soils afforded, it would also contribute to subtle changes in the waters of Big Lagoon. Virtually all effluent would ultimately end up in Big Lagoon. T.I. 234; T.III.45. Two channels connect Big Lagoon to Pensacola Bay to the east, and a single, more constricted channel connects it to Perdido Bay to the west. Tides influence the circulation of the Class III water within Big Lagoon, variously calculated to amount to some ten or eleven billion gallons of clean salt water. Through Pensacola Bay and Perdido Bay, Big Lagoon communicates with the Gulf of Mexico. As the tide rises, water from the adjacent bays enters the long and narrow reaches of Big Lagoon, at either end. As the tide ebbs, water in the lagoon (including a significant portion of bay water introduced by the preceding tide) flows out either end. ECUA's expert's claim that tides flush the lagoon in less than nine days did not take this back-and-forth movement into account, or look specifically at the four-billion gallon basin into which the brackish pond overflows. Big Lagoon lies south of the mainland and north of Perdido Key, one of the barrier islands paralleling the coast. These islands and waters north of them, extending as far as the southern boundary of the intracoastal waterway, comprise the Gulf Islands National Seashore. By rule, the waters of Big Lagoon south of the intracoastal waterway have been designated Outstanding Florida Waters. Two to three hundred yards wide, the intracoastal lies not far offshore the mainland. Water Quality Analysis of a single ground water sample revealed nutrient levels, but neither the applicant nor DER developed any data specific to Big Lagoon about nutrient levels there. Chemical analyses done on four samples of lagoon water (at petitioner's expense) revealed no nitrate nitrogen above detection levels in any of the samples, and no ammonia nitrogen above detection levels in three of the four samples, but disclosed 0.08 parts per million in the fourth. Three of the four samples contained 0.02 parts phosphorous per million, while the fourth had phosphorous in a concentration of 0.03 parts per million. Tests with water taken from Big Lagoon showed that the addition of both nitrogen and phosphorous compounds (but not the addition of one without the other) coincided with algal growth in one of four sets of samples, each set including a control in which such growth did not occur. In other samples of lagoon water into which algae were introduced, the addition of nitrogen, either alone or in combination with phosphorous, seemed to cause blue-green algae to predominate, instead of the dominant, indigenous pennate diatoms. In these experiments, ammonia chloride was added to produce nitrogen concentrations of 17.5 grams per liter, six times greater than would be allowed in the effluent, as much as 17 times greater than the concentration petitioner's expert predicted for wastewater reaching the lagoon, and two orders of magnitude above ambient levels. The experimenter also added sodium phosphate dibasic heptahydrate to create phosphorous concentrations of four grams per liter, which is also two orders of magnitude above levels naturally occurring in Big Lagoon. Special permit conditions limit (on an annual average) total nitrogen in effluent sent to Site F to 75 pounds per day, and phosphorous to one milligram per liter, which would amount to 25 pounds in three million gallons, the maximum daily flow. Permit conditions also prescribe limits for acidity and alkalinity (pH must be greater than 6.0 and less than 8.5), suspended solids, and biochemical oxygen demand. Basic dis- infection is required. Assuming ECUA disposed of three mgd at Site F, up to 25 pounds of phosphorous could be added to the estuary daily, on average, or more than a ton of phosphorous quarterly, if steady state were attained. Although three times as much nitrogen might occur in the effluent, oxidation and reduction would cause some nitrogen to enter the atmosphere as a gas instead of remaining dissolved until it reached the estuary. Not only organic components of the soil but also organic matter arriving in the effluent and accumulating on pond bottoms would contribute to denitrification. Salinity in the brackish pond would decline. A DER employee, Mr. Swartz, testified that placing three mgd of effluent in the planned percolation ponds "would not result in degradation of the surface water," (T. II. 127) citing "our experience here in Florida." Id. Whatever may be said as regards the brackish pond, no evidence gave substantial reason to question the accuracy of this opinion as it relates to waters south of the intracoastal waterway.
Recommendation It is, accordingly, RECOMMENDED: That DER deny the application, without prejudice to the filing of another after successful bench-scale or pilot-scale hydraulic testing and after ECUA has made arrangements for a ground water monitoring well from which samples unlikely to be affected by the effluent may be drawn. DONE and ENTERED this 2nd day of February, 1990, in Tallahassee, Florida. ROBERT T. BENTON, II Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 2nd day of February, 1990. APPENDIX Petitioner's proposed findings of fact Nos. 1 through 8, 13, 14, 16 and 18 have been adopted, in substance, insofar as material. Most of petitioner's proposed finding of fact No. 15 accurately recites testimony adduced, but Shuba testified that algal growth has been stimulated by nutrient concentrations comparable to those Dohms said would occur in water entering Big Lagoon, not in concentrations likely to exist once this wastewater-bearing contribution mixed with other water in the lagoon. Petitioner presented information about nutrient levels in lagoon water at hearing. Computer modeling suggested break out, which has been considered. Petitioner's proposed findings of fact Nos. 17 and 19 accurately recite the testimony. DER's proposed findings of fact Nos. 1, 2, 3, 4, 5, 10, 11, 12, 13, 15, 16, 17, 18, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 42 and 43 have been adopted, in substance, insofar as material. With respect to DER's proposed finding of fact No. 6, the rate of flow increases south of the proposed pond sites. With respect to DER's proposed findings of fact Nos. 7 and 8, seasonal high ground water elevations were not shown conclusively. With respect to DER's proposed finding of fact No. 9, the aquiclude lies 90 to 110 feet below the surface. With respect to DER's proposed finding of fact No. 14, the rule requires a five-day rest. With respect to DER's proposed findings of fact Nos. 33, 34 and 35, the current rules do require mounding analysis, and there seemed to be a consensus that ground water enhanced by effluent would seep to the surface downslope from the ponds. With respect to DER's proposed findings of fact Nos. 36 and 37 and 44, free form agency action is technically immaterial. With respect to DER's proposed findings of fact Nos. 38, 39, 40 and 41, effluent would have mixed with groundwater before reaching Big Lagoon, but increased levels of nitrogen and phosphorous could be detected, as a result. ECUA's proposed findings of fact Nos. 1, 3, 4, 5, 6, 8, 10, 11, 12, 15, 16, 17, 20, 23, 24, 25, 26, 27, 28, 36, 37 and 38 have been adopted, in substance, insofar as material. With respect to ECUA's proposed findings of fact Nos. 2, 13, 21 and 32, the evidence showed that it was not unlikely that effluent, after percolating through pond bottoms and mixing with groundwater, would seep to the surface down slope. With respect to ECUA's proposed finding of fact No. 7, proposed cell bottom elevations fall in this range. With respect to ECUA's proposed finding of fact No. 9, the evidence did not establish that the high water table will always be nine feet below the pond bottoms. With the induced mound, ECUA's proposed finding of fact puts it at one to two feet. With respect to ECUA's proposed finding of fact No. 14, the tidal range is too high and the calculation ignores the back and forth movement of waters at either end of the lagoon. With respect to ECUA's proposed findings of fact Nos. 18 and 19, the current standard pertains total nitrogen. With respect to ECUA's proposed finding of fact No. 22, freeboard will vary with rainfall and effluent levels. ECUA's proposed findings of fact Nos. 29, 30, 31 and 34 relate to subordinate matters. With respect to ECUA's proposed finding of fact No. 33, more than one analysis was done. With respect to ECUA's proposed finding of fact No. 35, the applicant has given reasonable assurance.

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. RECOMMENDED this 15th day of July, 1991, in Tallahassee, Florida. DIANE K.

The Issue Whether the Department should grant a permit to IMCF to mine and ultimately reclaim 145 acres of wetlands located primarily in Section 14, Township 31S, Range 23E, Polk County, Florida ("Section 14 Area") on the western edge of a larger wetlands system known as "Hookers Prairie."
Findings Of Fact Background and Procedural History On July 9, 1987, IMCF filed an application with the Department for a permit to mine phosphate rock from and then reclaim the Section 14 Area. The Section 14 Area is owned by IMCF. On December 2, 1987, in response to a determination of incompleteness issued by the Department, IMCF supplied additional information which supplemented and modified the original application. The application as augmented and modified was determined to be complete by the Department on December 7, 1987. Department representatives carried out onsite inspections of the Section 14 Area on September 22 and October 9, 14, and 19, 1987, and issued a written permit application appraisal. Based upon the information contained in the application and on the site visits, the Department determined to issue the requested permit to IMCF subject to certain draft permit conditions. The Department directed IMCF to publish notice of the Department's intent to issue the permit. The Department's notice of intent to issue was published in the Lakeland Ledger, a newspaper of general circulation in the location of the Section 14 Area on March 15, 1988. Petitioners objected to the Department's proposed issuance of the permit by filing their Petition to Intervene and Request for Formal Hearing with the Department on April 7, 1988. Petitioners have standing to intervene in this proceeding and participate as parties for the purpose of objecting to the issuance of the subject permit. Description of Proposed Mining Project The wetlands that make up the Section 14 Area are part of a larger 162 acre project area proposed to be mined and reclaimed by IMCF. This mining area is located to the south of the eastern portion of Bradley Junction, a small residential community. The Section 14 Area wetlands make up 131 acres of the overall project area. The remaining 31 acres of uplands involved in the proposed mining project are not subject to Department permitting requirements. IMCF has all necessary permits and approvals to gain access to the upland areas to carry out mining operations. These uplands areas are located primarily in the northernmost part of the project area directly abutting the location of certain residences and churches in eastern Bradley Junction. The jurisdictional wetlands in the Section 14 Area are located no closer than 450 feet from a residential structure in Bradley Junction. Most of the wetlands in the Section 14 Area are substantially farther away from the Bradley Junction residences. The initial step in the mining process will be to construct a ditch and berm system around the Section 14 Area. This ditch and berm system will effectively segregate the mining area from adjacent wetland areas that are to remain undisturbed. Approximately 99 acres of the Section 14 Area wetlands will actually be mined; the remaining 32 acres will be disturbed by the construction of the ditch and berm system. Following the construction of the ditch and berm, land clearing will take place. Once land clearing is completed, mining operations will commence. In phosphate mining operations, large, electrically-powered draglines are used. The dragline first removes and casts aside the "overburden" which is the earthen material that over lies the "matrix." The matrix is the geologic deposit that contains phosphate rock. The dragline extracts the matrix and places it into nearby pits where high- pressure waterguns are used to create a slurry of the matrix material. This slurry is then pumped to the beneficiation facility several miles distant from the mining operations where the matrix slurry is processed to extract the phosphate rock. The matrix is composed primarily of three major components: phosphate rock, sand, and clay. In the beneficiation process, the phosphate rock is separated from the other two components. Residual clays are then pumped to large settling areas where the clays are allowed to settle and consolidate prior to reclamation. No clay settling area is proposed to be located in the Section 14 Area. The sand "tailings" that are generated in the beneficiation process are pumped back to mined areas for use in reclamation programs. Sand tailings will be used in the reclamation proposed for the Section 14 Area. IMCF proposes to initially carry out ditching and berming activities in the Section 14 Area. The central and southern portion of the project area is planned to be mined during the period from July 1989 and June 1990. The dragline will then mine an area to the west outside of the project area. The dragline will return to mine the northern portion of the project area in May 1991. Actual mining operations in the northern portions of the Section 14 Area wetlands and the uplands near Bradley Junction residences will occur over approximately a seven-month period and the dragline will depart the area in December 1991. There are approximately 800,000 tons of phosphate rock underlying the Section 14 Area wetlands. After extraction and beneficiation, this rock will be used for the production of phosphate fertilizer or other phosphate-based products. Project Modifications IMCF has agreed to the following modifications to the Section 14 Area mining and reclamation project as originally proposed in July 1987: The southern boundary of the Section 14 Area has been moved to avoid encroachment on a small stream channel in the upper reaches of the South Prong of the Alafia River, the outlet from Hookers Prairie. The project has been modified to conform to setback requirements recently adopted by the Board of County Commissioners of Polk County. Under the revised setback requirements, the edge of a mine cut may come no closer than 100 feet from the IMCF property boundary or 250 feet from an occupied residence, whichever distance is greater. In response to concerns about noise and lights associated with mining operations, IMCF has agreed to restrict the hours of mining operations. Mining operations will not take place during the period from 11:00 p.m. to 7:00 a.m. when the dragline cab is located within 700 feet of a residence. In addition, mining operations will be suspended on Sundays during the period from 7:00 a.m. through 3:00 p.m. when a dragline cab is located within 700 feet of any place of worship in the Bradley Junction community. The Polk County Mining Ordinance requires that either a berm or a wire fence be constructed on the perimeter operations to limit unauthorized access. IMCF has agreed to construct both a berm and a solid wooden fence, at least six feet high, along the IMCF property boundaries adjacent to residences located in the Bradley Junction community. IMCF has agreed to expedite the reclamation of areas mined adjacent to residences in the Bradley Junction community. The area encompassing the first mine cut closest to the residences (a distance of 250 to 300 feet) will be recontoured and revegetated within 90 days following completion of mining in the area. The area encompassing the first two mine cuts (a distance of 500 to 600 feet) will be recontoured and revegetated within six (6) months following completion of mining in the area. Type, Nature and Function of Section 14 Area Wetlands The Section 14 Area is composed of approximately 127 acres of herbaceous (shrubby) wetlands and approximately 4 acres of young hardwood (forested) wetlands. Western Hookers Prairie, including the Section 14 Area, has been adversely impacted by land use activities over the last several decades. Parts of the area have been drained and cleared to accommodate agricultural uses. The resulting widely fluctuating water levels have induced the extensive growth of what the Department considers to be undesirable "nuisance species" such as cattails and primrose willow, in these areas. Other areas, especially in the southern portion of the Section 14 Area, contain some relatively diverse herbaceous wetland systems. The Section 14 Area also has been adversely impacted to some extent by emergency releases of phosphogypsum and acidic process wastewater generated by the chemical manufacture of phosphate-based fertilizer. Such spills occurred in the 1950s and 1960s and resulted in the deposition of high levels of phosphorous and fluoride in western Hookers Prairie. However, the Section 14 area is less affected than eastern parts of the Western Prairie due to a natural slight rise in elevation along the eastern edge of Section 14, causing a natural flow of water containing the contaminants generally south around Section 14. Wetland systems, in general, can perform certain valuable ecological functions. These functions include: nutrient retention/removal, sediment trapping, flood storage desynchronization, groundwater recharge, food chain support, wildlife habitat, and recreation. Certain wetland systems also serve a shoreline protective/wave dissipation function but that function is not relevant to herbaceous wetland systems like the Section 14 Area that are not adjacent to open water. Because of the nature of the Section 14 Area and the stresses previously imposed upon it, its ability to perform wetland functions has been reduced. The nutrient retention/removal function refers to the ability of the vegetation in wetland systems to remove excess nutrients from water. The Section 14 Area does not perform a significant nutrient retention/removal function. The available data indicate that waters leaving western Hookers Prairie at its outlet to the South Prong of the Alafia River contain more nutrients on balance than do waters entering the system. It is not uncommon for wetlands that are in headwaters of a water system to be net exporters of nutrients. In addition, in this particular area, the historical spills of phosphogypsum and acidic process wastewater have overloaded the sediments in the area with nutrients. The sediment trapping function refers to the ability of wetland systems to filter sediment (suspended particulate matter) from water as it travels through the wetland area. The Section 14 Area performs a reduced sediment trapping function. Although some of the water entering the Section 14 Area comes from Whiskey Store Creek to the north, some of the water entering Section 14 has already traveled relatively long distances through the rest of western Hookers Prairie so that most of the water entering the Section 14 Area does not contain high levels of sediments. As more and more parts are excised for phosphate mining, the importance of the sediment trapping function of the remaining portions, even Section 14, increases, at least until reclamation projects succeed. See "J. Cumulative Impact," below. The flood storage/desynchronization function refers to the ability of a wetland system to store rain water generated during storm events and then to release this water gradually, thus reducing the likelihood of downstream flooding. Hookers Prairie, as a whole, does serve a valuable flood storage/desynchronization function. The approximately 130 acres involved in the Section 14 project area only amount to three to four percent of the overall water storage capacity in the affected area. But the Hookers Prairie wetlands have an approximately two foot thick layer of peat that acts as a sponge to absorb water during inundation and slowly release the stored water over time. It could be misleading to compare the storage of wetland to other water storage acreage on an acre for acre basis. Again, as more and more parts of the Prairie are excised for mining, the importance of the remaining areas increases, at least until reclamation projects succeed. IMCF did not give reasonable assurances as to the cumulative impact of the loss of Section 14 and the other areas under permit on the water storage capacity of the catchment area. See "J. Cumulative Impact," below. The ground water recharge function of wetlands refers to those situations in which a wetland is connected to an underlying groundwater aquifer system in such a way that surface water flows into the wetland system and then down into the underlying aquifer system. The underlying aquifer system is thus "recharged" by the infusion of surface water through the wetland system. The Section 14 Area does not perform any significant groundwater recharge function. Hookers Prairie, including the Section 14 Area, is a topographic depression. Therefore, water can flow out of the uppermost aquifer system (known as the surficial aquifer) into the wetlands, but the reverse is not true. Furthermore, the water in the wetland area cannot move down into lower aquifer systems (such as the intermediate aquifer or the Floridian aquifer) because of the existence of geologic confining layers that underly the Section 14 Area and inhibit vertical groundwater flow. The food chain support function refers to the ability of a wetland to produce organisms or biological material that is used as food by other organisms either in the wetland itself or in surface water areas downstream of the wetland system. The Section 14 Area performs some food chain support functions. Food chain support can be performed in three ways. First, dissolved nutrients, such as phosphorous and nitrogen, can be released into the water. Because of the prior spills into Hookers Prairie, the area is already discharging nutrients in amounts that are normally considered to be high. The second mechanism for performing food chain support is the physical flushing of small aquatic organisms downstream to feed the fish or other larger aquatic organisms. Studies carried out by the United States Environmental Protection Agency indicate that the small organisms found in the downstream reaches of the South Prong of the Alafia River do not appear to be similar to those found at the point of discharge from Hookers Prairie. These data indicate that Hookers Prairie produces and releases this type of food chain support but that its direct impact does not extend significantly into the southern reaches of the South Prong of the Alafia River, as compared to the total production from other tributaries of the river. The third type of food chain support is the release of detrital material (partially decomposed vegetation). Detrital material generated in much of Hookers Prairie is likely to be retained in the Prairie because of the sediment/trapping filtration function discussed above in Finding No. 17(b). However, being adjacent to the outflow from the Prairie to the South Prong, Section 14 could be expected to deliver a larger share of detrital material than the portions of the Prairie further east. The Section 14 Area provides a wildlife habitat function although it does not appear to serve as diverse a group of wildlife as is served by the eastern portion of Hookers Prairie. The Section 14 Area is not utilized for recreational purposes. It is densely vegetated so that access by man is difficult. There are no open water areas that could be used for hunting or fishing. Mitigation IMCF proposes to mitigate the temporary loss of function caused by the mining of the Section 14 Area by reclaiming the area following the completion of mining operations. The first step in reclamation will be the pumping of sand tailings back into the project area to create a land surface at approximately the original grade. The previously moved overburden material will then be spread and recontoured. Stockpiled organic muck material will then be spread over the reclamation area to provide a nutrient source to support plant growth. Department representatives will review and approve the final contours to assure that they are similar to those found in the original natural environment. Following completion of the contouring, the portion of the project area that will be reclaimed as a wetland will be inundated with water and then revegetated with desirable wetland species. The reclamation of the Section 14 Area will be subject to extensive monitoring by IMCF. This monitoring will involve short- and long-term vegetation monitoring and water quality monitoring. The results of this monitoring will be submitted to the Department, and the project will not be released from regulatory scrutiny until certain success criteria are met. During the period of recontouring, revegetation, and monitoring, the berm around the Section 14 Area will remain in place to isolate the area from the adjacent Hookers Prairie system. Once the Department determines that the vegetation in the Section 14 Area has been successfully reestablished, the Department will authorize IMCF to install culverts in the berm to allow for the gradual introduction of exchange of waters between the reclaimed area and the natural Hookers Prairie system. Following this process, after approval by the Department, IMCF will remove the berm area by pushing it back into the ditch and will replant the disturbed area in the previous location of the berm with desirable herbaceous wetland species. At that point, the reclaimed area will be totally reconnected to the rest of the western Hookers Prairie. The reclamation of the Section 14 Area will involve the recreation of approximately 121 acres of herbaceous wetlands. This is approximately the same amount of herbeceous wetlands that were mined or disturbed in the Section 14 Area. In addition, 24 acres of forested wetlands will be created. This is approximately six times the number of area of forested wetlands that were in the Section 14 Area prior to mining operations. IMCF has had extensive experience in the reclamation of wetland systems in Florida. The company has reclaimed over 3,000 acres of wetlands over the last ten years. The company's experience includes the reclamation of both herbaceous wetland systems and forested wetland systems. With regard to the proposed mitigation, the primary issue at dispute in the hearing was whether IMCF can control the growth of nuisance species, such as cattail and primrose willow, in accordance with the Department's current policy. This policy, which will be implemented as a condition of any permit issued in this matter, is that nuisance species shall be limited to ten percent or less of the total cover or, if these species exceed ten percent of the total cover, their density must be declining over several years. IMCF would use several methods to limit the growth of nuisance species in the reclamation area. The company will flood the reclamation area immediately following recontouring. In addition, the company will assure that water levels are maintained in the project area throughout the vegetation period. These hydrological controls are designed to preclude seeds from nuisance species growing nearby from blowing into the area and propagating. These seeds will not propagate under water. In addition, the project area would be covered by a two-inch to six- inch layer of organic mulch material. The use of such organic material inhibits the growth of nuisance species. Finally, IMCF will plant desirable wetland species on a relatively dense basis; i.e., on three- to five-foot centers. When established, these desirable species are expected to quickly grow and outcompete any nuisance species that may enter the area. There is legitimate concern about the growth of nuisance species in the reclamation area and about the company's ability to eradicate or remove nuisance species if in fact the area does become invaded. There also is legitimate concern that the disturbance caused by the construction of the perimeter berm might induce the growth of a five to fifteen foot band of nuisance species outside of the Section 14 Area. Even if this occurred, it would not have a significant impact on the Hookers Prairie system, which already contains a large amount of "nuisance species." Finally, there is a concern whether nuisance species can be kept out of the ditch and berm area after the berm is leveled since there no longer would be hydrological controls in place. I am persuaded by the weight of the evidence presented in this matter that, with the following additional special permit conditions, IMCF has provided sufficient reasonable assurances to the Department that it will be able to successfully reclaim the Section 14 Area and to control nuisance species growth in accordance with applicable Department policy: that, in accordance with existing Department policy, the plant material used for revegetation for the reclamation project be plants that grew naturally within 50 miles of the reclamation site; that the elevations in the reclamation site be "fine-tuned" after recontouring but before removal of the ditch and berm to approximate existing elevations as closely as possible except when deviations from existing elevations might be desirable to better accomplish the goals of the reclamation project and reduce nuisance species; that, upon removal of the ditch and berm, all nuisance species (cattails and primrose willow) that may have invaded the perimeter band along the berm (see Finding 25, above) be removed and revegetation over the ditch and berm area be on two to four foot centers to aid competition with any invading nuisance species. Evaluation of Project Impacts Extensive testimonial and documentary evidence was presented at the hearing concerning a wide variety of potential impacts associated with the mining of the Section 14 Area. Potential impacts addressed included the impacts of mining and reclamation upon surface water and ground water quality, upon surface water flow conditions, and upon the availability of ground water for use as a portable water supply by the Bradley Junction residents. In addition, evidence was presented concerning potential impacts upon the Bradley Junction community in the form of fugitive dust, physical damage to structures in the community, and impacts associated with machinery noise generate during the mining and reclamation process. Surface Water Quality The perimeter berm and ditch system around the Section 14 Area will completely segregate the mining operations from the adjacent Hookers Prairie wetland system and the South Prong of the Alafia River. Therefore, the mining operations will not have a direct adverse impact upon the quality of surface water outside of the Section 14 Area. As noted in Findings Nos. 17(a) and 17(b), the temporary exclusion of just the Section 14 Area from the Western Hookers Prairie wetlands system will not have a significant adverse water quality impact. But, see "J. Cumulative Impact", below. Construction of the berm will not significantly affect dissolved oxygen levels in Hookers Prairie even in the areas immediately adjacent to the berm. Natural dissolved oxygen levels in the Hookers Prairie system are relatively low, and its waters are normally in a static or stagnated condition. (Construction of the berm probably will elevate dissolved oxygen levels in some areas near the berm by creation of small open water areas and lower levels in other areas where discarded plant material accumulates.) The weight of the evidence indicates that the construction of the berm will not cause a violation of state water quality standards outside of the Section 14 Area. During the reclamation process, water quality monitoring will take place and the resulting data will be presented to the Department. Upon Department approval, the reclaimed wetland system will be gradually reconnected to the natural Hookers Prairie system. The water quality in the Section 14 Area after reclamation will comply with applicable State water quality standards. Ground Water Quality Several residents of the Bradley Junction community have raised concerns about the quality of the water withdrawn from their portable water supply wells. While it does appear that water from certain of these wells may be of substandard quality, this condition is not a result of phosphate mining operations and will not be affected by the mining and reclamation of the Section 14 Area. The basis for this finding is: Mining in the Section 14 Area will take place in the surficial aquifer system. Portable water supply wells in the Bradley Junction community area draw water from the intermediate aquifer system. The intermediate aquifer system is separated from the surficial aquifer system by a thick, relatively impervious clay layer that significantly impedes the vertical flow of ground water. The Section 14 Area is located hydrologically downgradient from the Bradley Junction community. Any seepage from mining operations will move away from Bradley Junction, not toward that location. The quality of the water that will be found in the mine cuts and ditches in the Section 14 Area is very good and probably would not significantly adversely impact the quality of the portable water drawn from Bradley Junction water supply wells even if it were physically possible for the mining-related waters to reach the wells. The Polk County Public Health Unit of the Department of Health and Rehabilitative Services carried out a study of the quality of portable water in the Bradley Junction community. The study indicates that water from certain of the wells exhibit elevated levels of fecal coliform. The probable source of this contamination is improper sanitary conditions in the area near the well locations. There is no evidence to indicate that phosphate mining operations have any impact on the quality of the water in these wells. Surface Water Flow Conditions At this time, the construction of the berm and ditch system and the mining in the Section 14 Area will have only a minor impact on surface water flow conditions outside of the Section 14 Area. The proposed mining and reclamation project itself will not cause an increased likelihood of flooding in downstream areas nor will it cause increased erosion in the South Prong of the Alafia River. IMCF has applied for and received a "Works of the District" permit for the Section 14 Area from the Southwest Florida Water Management District, the state agency primarily responsible for evaluating the impact of construction activities on surface water flow conditions. But see "J. Cumulative Impact," below. Ground Water Availability The digging of mine cuts in the surficial aquifer can result in a drawdown or lowering of the water table in the surficial aquifer system. If controls were not employed by IMCF in connection with the mining of the Section 14 Area, the surficial aquifer in the area of the Bradley Junction community could be drawn down by as much as five feet below natural levels. IMCF has applied for and received a consumptive use permit from the Southwest Florida Water Management District, the state agency primarily responsible for regulating the use of ground water in the State of Florida. The consumptive use permit requires IMCF to maintain the water level in the surficial aquifer at historic levels taking into account the natural variations in the water table that occur during the year. IMCF will comply with the conditions of the consumptive use permit by the use of two positive control methods. The perimeter ditch surrounding the project site will serve as a hydrological barrier or recharge ditch that will maintain the surficial aquifer water levels at historic levels. In addition, during mining operations, the dragline will cast the removed overburden material against the face of the mine cut. This procedure will have the effect of sealing the face of the mine cut and inhibiting the flow of ground water from contiguous areas into the mine cut. In accordance with the consumptive use permit, IMCF will monitor water levels adjacent to the Section 14 Area to assure compliance with the drawdown restrictions. 1/ As noted in Finding No. 32(a), the portable water supply wells in the Bradley Junction community draw water from the intermediate aquifer system. Water levels in the intermediate aquifer system are not significantly affected by the water levels in the surficial aquifer. The two systems operate independently by virtue of the thick confining layer that separates them. Mining operations in the surficial aquifer in the Section 14 Area will have no effect on the water levels in the intermediate aquifer system underlying the Bradley Junction community. Therefore, the proposed mining operations will have no effect upon the availability of water in the Bradley Junction portable water supply wells. Dust Dragline operations and slurry pit operations are wet process activities that do not generally result in the emission of dust. Dust can be emitted as a result of vehicle travel on access roadways, by land clearing operations, and during reclamation activities especially in the dry season under high wind conditions. IMCF will control dust emissions from the Section 14 Area by use of water trucks to keep access roads moist. In addition, IMCF will curtail land clearing and reclamation operations during periods when high winds are prevailing in the direction of the Bradley Junction community. Physical Impact on Structures Certain residents of the Bradley Junction community have complained that nearby mining operations have caused physical damage to their homes. The evidence presented at the hearing, however, demonstrates that neither vibration caused by the equipment used in mining operations nor the construction of mine cuts will cause any adverse physical effects on nearby structures. The basis for this finding are as follows: Vibration measurements taken in the vicinity of the type of equipment that will be used in the Section 14 Area demonstrates that the vibration levels that will be experienced at the residences closest to the mining operations are far below the level that would cause any structural damage. These worse case conditions would be experienced at a point approximately 250 feet from the mining operations. It should be noted that these conditions will only occur when mining operations are taking place in upland areas outside of the Department's jurisdiction. Vibration impacts resulting from mining activities in the more distant jurisdictional wetland areas are even less significant. A slope stability analysis carried out by Dr. John Garlanger demonstrated that the construction of a mint cut at a distance no closer than 250 feet from a residence will cause no adverse impact on the structural integrity of the residence. This conclusion is underscored by the fact that the dragline, which is larger and heavier than the typical Bradley Junction home, will safely operate very near the edge of the mine cut without significant risk of slope collapse. Any current physical damage to structures in the Bradley Junction community is probably the result of age, water damage, improper site preparation, and other improper construction techniques. Noise Draglines, pumps, and other pieces of heavy equipment to be used in the mining and reclamation of the Section 14 Area will produce noise that is audible to, and will be annoying to, the people living near the project. None of the expected noise levels will exceed the guidelines established by the Federal Highway Administration ("FHA") for construction of highway projects near residential communities. The FHA guidelines require that noise levels may not exceed 70 decibels more than 10 percent of the time. Even in the worst case situation, which involves mining in the upland areas no closer than 250 feet from a residential structure, the expected noise levels will not exceed the FHA guidelines. When mining operations occur at more distant locations, the noise experienced in the Bradley Junction community will be proportionately reduced. The suggested United States Environmental Protection Agency noise level limitation is 55 decibels. At the 55-decibel level, there was scientific evidence that noise exposure resulted in irritability and sleep loss, but no actual hearing loss would occur. The 55 decibel EPA guideline is calculated differently than the FHA guidelines. The maximum levels expected to occur near the Section 14 Area based on the data collected by Mr. Nelson were essentially in compliance with the EPA recommendations. Furthermore, the predicted noise levels reflect outside noise levels. The noise levels inside the structures in the Bradley Junction community would be below the recommended EPA levels because of noise attenuation by the structure. The mining operations would have a reduced impact upon sleep because the company will not operate between the hours of 11 p.m. and 7 a.m. when close to the residences. Mining operations in the northernmost portion of the project will occur over a period of seven months. Reclamation in the immediate vicinity of the Bradley Junction community will be completed within six months following mining operations. The predicted worst case conditions during mining and reclamation will occur only over a few weeks with regard to any particular residence. These worst case conditions will occur in upland areas outside the Department's jurisdiction. Noise resulting from activities taking place within jurisdictional wetlands is at even lower levels. Polk County Ordinance. The governmental body primarily responsible for public health concerns such as dust, noise and vibration impact or structures is the local government, Polk County. Polk County has enacted a mining setback ordinance which is less restrictive than other nearby counties - - only 250' from the nearest residence versus 500' in Hillsborough County and 1000' in Manatee County. Under the Polk County ordinance, IMCF is able to mine as close to Bradley Junction residents as it proposes. Archeological Resources There are no significant historical or archeological resources in the Section 14 Area. Cumulative Impact Hooker's Prairie is a wetlands marsh system which comprises the headwaters of the South Prong of the Alafia River. The Section 14 project area is an integral part of the Prairie. Although IMCF's case thoroughly addressed all other issues raised by the opponents of the Section 14 project-- including noise, dust and even damage to structures from vibration-- its case conspicuously failed to as clearly address the question of cumulative impacts. It is not clear from the evidence if Hookers Prairie historically was 3000 acres, 3500 acres or some other size. Likewise, the current size of the Prairie, unmined and unsevered, also is unclear from the evidence. DER has issued five previous permits for phosphate mining in Hooker's Prairie. These permits are to W. R. Grace for approximately 1000 acres in the Eastern Prairie and IMCF for approximately 120 acres in the Western Prairie, including the recent IMCF Section 12 project involving mining and filling approximately 100 acres of Hooker's Prairie. It is not clear from the evidence how much of the 1000 acres already has been mined. DER's appraisal report, dated November 4, 1987, states that there has been recent mining in Section 18 in the Western Prairie. It points out that, as a result, cattails have intruded into Section 13 of the Prairie from the east. The report states that, aside from the Section 14 project area, there were then only 720 acres of wetland left in the Western Prairie, which has been almost blocked from the Eastern Prairie by mining activities, 620 in Section 13 and 100 in the west side of Section 7. It also states that almost 700 acres "in [the Section 14 project) area alone" were then permitted for mining. Although it is not clear, this appears to consist of 96 acres IMCF had under permit "in this immediate vicinity" and 580 acres of the Prairie to the east. It is not clear whether this acreage is in addition to, or part of, the acreage referred to in Finding 48, above. To date, no one has successfully restored mined wetlands in Hooker's Prairie. IMCF has restored a small, approximately 20 acre tract of wetland in the Western Prairie, but no success determination has yet been made. IMCF's approximately 100 acre restoration in Section 12 is underway. Efforts by Grace to restore mined wetland in the Eastern Prairie were delayed while Grace and DER negotiated an alternative to the original "land and lakes" restoration concept approved under the DER permits. A wetlands restoration concept finally having been agreed to, restoration now is underway. W. R. Grace has plans to mine the entire remaining wetlands of Hookers Prairie in the foreseeable future. Wetland restoration takes approximately two to four years. IMCF plans to mine in Section 14 from July, 1989, through December, 1991. Restoration is planned to take place through December, 1994. It may take longer. During part of this time period, IMCF's 120 acres of restoration in the Western Prairie still will not be functional. There was no evidence to suggest that the Grace wetlands restoration would be completed before IMCF plans to complete its Section 14 restoration project. There was no evidence as to when Grace is expected to complete any restoration of the 1000 acres it has under permit in the Eastern Prairie. The same would be true of any other parts of the wetlands that may be under permit. In light of the substantial, though undeterminable, reduction of the size of Hooker's Prairie from its historical size, the cumulative impact of removing an additional 131 acres of wetland from the system for approximately five or more years is significant. During this time, the size of functional wetland in the Prairie may be close to just half its historical size or even less. IMCF has not given reasonable assurances that the cumulative impact of the loss of another 131 acres of Hooker's Prairie for five or more years, combined with the recent reduction in the size of the functional wetland, will not be contrary to the public interest. Further phosphate mining in Hooker's Prairie should await successful restoration of wetlands in areas already under permit for mining operations.
Recommendation Based on the foregoing Findings Of Fact and Conclusions Of Law, it is recommended that the Department of Environmental Regulation deny the application of IMC Fertilizer, Inc., to mine for phosphate in Section 14, Hooker's Prairie, at this time. RECOMMENDED in Tallahassee, Florida this 14th day of February, 1989. J. LAWRENCE JOHNSTON Hearing Officer Division of Administrative Hearings The Oakland Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 FILED with the Clerk of the Division of Administrative Hearings this 14th day of February, 1989.
The Issue Whether application 23181 for a consumptive use water permit should be granted, pursuant to Chapter 383, Florida Statutes. Prior to the hearing, 16 individuals in the Wabasso, Florida, community petitioned to intervene as parties in this proceeding. By Order, dated August 26, 1976, intervention was granted. Thereafter, counsel for the Wabasso Citizens Association, a private, unincorporated association that included the 16 prior intervenors, requested that intervention include all members of the association. There being no objection to the foregoing request, intervention was granted accordingly. The public hearing in this matter included 22 exhibits and the testimony of 21 witnesses, nine of whom were members of the public. Lists of the exhibits and public witnesses are attached hereto. On January 8, 1975, the Town of Indian River Shores, Florida (hereinafter "Town"), and Lost Tree Village Corporation, Indian Rivers Shores, Florida (hereinafter "Lost Tree"), filed application 23181 for a consumptive use water permit with the Central and Southern Florida Flood Control District (hereinafter "District"). The application requested a permit for the withdrawal of 393 acre feet per year of groundwater from two wells located on a parcel of land owned by Lost Tree at Wabasso, Florida. The requested use was for irrigation of two golf courses located on land owned by Lost Tree known as John's Island, a residential community located within the Town, and as an emergency public water supply for the Town. It was proposed that the water be transported by pipeline owned by Lost Tree from Wabasso to John's Island, a distance of several miles. Although the matter was set for public hearing to be held on February 4, 1975, an unfavorable staff report of the District, dated January 30, 1975, resulted in an indefinite postponement of the hearing. A hydrogeological report was prepared for Lost Tree by a consulting firm on February 12, 1976, and submitted by the applicant to the District. A subsequent staff report of the District was prepared on July 28, 1976. Thereafter, the matter was noticed for hearing to be held August 31, 1976. Pursuant to the request of intervenors, a continuance was granted until September 29, 1976. (Exhibits 5,6,7,8,19)
Findings Of Fact The Town is a municipality that was incorporated in 1953. It is located east of the Indian River on an island and extends from the north boundary of Vero Beach for over 4 miles along the Atlantic ocean. In 1969, Lost Tree commenced developing a 3,000-acre tract of land located within the Town as a residential community. Prior to the initiation of this project, there had been very little development in the Town. In order to attract residents to John's Island, two 36-hole golf courses were constructed on the property, known as the North and South Courses, covering approximately 180 acres. At the present time, John's Island comprises over 600 residences, consisting of single and multiple family units, ranging in price from $65,000 to $500,000. The Town has a population of about 1,200, with 65 percent residing at John's Island. The present assessed value of property located in the Town is about $160,000,000 of which almost $66,000,000 is attributable to property in John's Island. The private golf club at John's Island has approximately 500 members, including about 150 from Vero Beach. The golf courses are considered to be the "heart" and "life-blood" of the community (Testimony of Ecclestone, Miller; Exhibits 5,11,12). The water supply of the Town comes from the water system of the City of Vero Beach, pursuant to contract, via a 16" water main which crosses the Indian River and ends at the northern boundary of Vero Beach. There, it is tied into a 12" water main of the Town. The Town has a one million gallon capacity underground storage tank and a 100,000 gallon overhead tank. The 16" main is the only waterline that crosses the Indian River and, in the event of a rupture, the Town would be limited to its stored supplies (Testimony of Miller, Little, Exhibits 5,17). The John's Island golf courses require irrigation of approximately 70 acres. In the past, irrigation water has been obtained from a system of shallow wells on the property, treated sewage effluent from the surrounding community, and stormwater, all of which is discharged into two ponds located on the courses. Additionally, treated potable water is obtained from the City of Vero Beach through two two-inch water meters that were installed in 1975. Prior to that time, an undisclosed amount of city water was obtained for irrigation and other purposes through city meters installed on fire hydrants in the area. The use of city water was required in order to supplement the resources available on the John's Island property. During the period May, 1975, through August, 1976, the amount of water obtained from the City of Vero Beach that was used for golf course irrigation totaled 54,057,000 gallons, an average of some 110,000 gallons per day. At the present time there is no water problem, insofar as irrigation is concerned, on the South Course which obtains irrigation water from sewage effluent and a number of shallow wells. However, test samplings over the years have shown a gradual increase in the amount of chlorides in the water and it is questionable whether such water will continue to be suitable for irrigation in the foreseeable future. Recent tests show the chloride content of the water at 450 ppm. The type of Bermuda grass on the golf courses can grow satisfactorily with water containing not more than 1,000 ppm. City water is used only on the North Course. The water obtained from the shallow wells in that area is highly saline in content. A recent water test showed a chloride content of 3,800 ppm. Additionally, immediately before an eight inch rainfall which lowered the chloride content to the foregoing figure, the greens on the North Course tested at 6,300 ppm in chloride content (Testimony of Luke, Little, Exhibits 6,7). During periods of drought, the City of Vero Beach has requested John's Island and other water users to either curtail or stop the use of city water for non-domestic purposes. Such requests have been received approximately six times during the past year. In April, 1976, the city water used for golf course irrigation at John's Island was shut off for a period of eight days as a result of a request from officials of Vero Beach. If insufficient irrigation water is not received for a period of 10 days to two weeks, it is extremely probable that a golf course would have to be replanted at an approximate cost of $60,000.00 to $80,000.00 and would require a period of six months for suitable growth. Both the Town and John's Island always cooperated fully with the requests of Vero Beach to curtail water use (Testimony of Luke, Miller, Little, Exhibit 17). At the time irrigation water sources were being explored at John's Island, a test well was drilled to a depth of 2020 feet into the Floridan aquifer underlying the property, but an inadequate quantity of water was developed. Lost Tree owns some 25 acres of land at Winter Beach, Florida, which is located west of John's Island across the Indian River. Although test wells there produced satisfactory water, it was not feasible to use this source due to prohibitions against excavation for such purposes in the Indian River. Due primarily to economic considerations of the high cost of using treated city water for golf course irrigation, and the inconvenience and possible hazards of water interruptions from that source, Lost Tree decided to supplement its resources from water withdrawn from wells to be located on a 4.869 acre tract of land it purchased in Wabasso. Although a deep well was considered at that site, state agencies advised that the Floridan aquifer was overloaded in that area to a degree of 200 percent. Accordingly, in 1973, two ninety-foot deep wells were constructed on the site approximately 500 feet apart into the underlying shallow aquifer. Pump tests showed that the chloride content was within satisfactory limits. Thereafter, Lost Tree in its own name and that of The Town, obtained necessary rights-of-way and permits for the placement of a system of pipes for transportation of water from the Wabasso wells to John's Island. These consisted of a 16" water line from the Wabasso site east over a newly constructed bridge and several existing bridges to Highway A1A where the size of the line south to John's Island was decreased to twelve inches. An agreement was entered into between Lost Tree and the Town on December 19, 1974 whereby the former agreed to supply emergency needs of the Town from water obtained from the Wabasso wells. About that same time, the pipe system was completed and the present application filed with the District (Testimony of Lloyd, Ecclestone, Exhibits 2,6,9). The area immediately surrounding Lost Tree's land in Wabasso consists primarily of residences, groves, and trailer parks. The residents of the unincorporated Wabasso area depend solely upon the shallow aquifer for their domestic water needs since there are no utility services in the area. Grove irrigation normally is accomplished by deep wells to the Floridan aquifer. After the application herein was filed in January, 1975, numerous letters of objection to the proposed withdrawal were filed with the District by residents of the Wabasso community and from local organizations. These objections, for the most part, expressed apprehension that the applicants would be withdrawing far more water from the well field than their fair share based on the size of Lost Tree's land in Wabasso. The objectors also claimed that the requested withdrawal would have a serious detrimental effect on existing users. They further protested the concept of extracting potable water from one area and transporting it to another area for irrigation use on recreational facilities. The initial Staff Report of the District on January 30, 1975, took such objections into consideration and recommended denial of the application based on the unsuitability of the well field site. It found that withdrawal of the requested water for golf course irrigation was not a reasonable and beneficial use because it greatly exceeded the water budget for the site, harmed existing legitimate users in the area by creating drawdowns of several feet which would increase the possibility of potable water supply wells running dry, harming potential future legitimate users by lowering the water table and exporting the water that they might have utilized, and because it threatened to harm such users and the resource itself by "upconing" saline water from the bottom of the aquifer into the fresh water producing zone of the aquifer. Although the report stated that there would be no objection to permitting an allocation on the order of 7.5 acre feet per year, which was the equivalent to the water crop, it was not recommended because such an allocation would do little to meet the applicant's needs for irrigation water (Exhibit 6, Composite Exhibit 20). Recognizing the need for further studies to support its application, Lost Tree hired a firm of consulting groundwater geologists and hydrologists to conduct an investigation of potential sources of irrigation water for both the John's Island and the Wabasso sites. The study confirmed prior conclusions that it was not practicable or feasible to develop the necessary irrigation water from sources available at John's Island. As to the Wabasso area, the report found that the shallow aquifer was not being fully utilized and that extraction of the proposed quantity of water would not exceed the capacity of the aquifer to provide it. It also determined that the presence of a continuous layer of impermeable clay within the Hawthorn formation effectively separates the Floridan from the shallow aquifer. No interference in the water levels of the Floridan aquifer should occur nor is it likely there would be salt water intrusion into the shallow aquifer. However, based on the formulation of a "mathematical model," it was predicted that the proposed withdrawal could adversely affect existing shallow wells within a few hundred feet of the applicant's well field by "drawdown" which could lessen the pumping ability of centrifugal pumps. Nearby existing wells, such as those located in a trailer park immediately west of Lost Tree's well field, could lose suction in pumping and thereby owners might experience delay in extracting water from the wells (Testimony of Amy, Exhibits 4, 8). Although one Wabasso resident who owns property near Lost Tree's wells has experienced a decrease in pressure in her well and poor quality water, and another nearby resident's well went dry, there is no clear evidence that Lost Tree's drilling of its two wells and consequent testing thereof caused these problems. Testimony of other Wabasso residents expressed their apprehension as to possible salt water intrusion and unavailability of water in the shallow aquifer if the requested withdrawal is approved. Other residents and public witnesses challenged the fairness of permitting one land owner to deplete local water supplies by withdrawals for transport to another area for recreational purposes (Testimony of Chesser, McPherson R., Pangburn R., Jackson, Mrs. S.B., Kale, Stout, Wintermute, Pangburn, K., Bidlingmayer, Willey, Gertzen). The District Staff Report, dated July 28, 1976, as supplemented by an addendum, dated August 30, 1976, reviewed the hydrogeological study submitted by the applicants and concluded that withdrawal of a specified amount of water from Lost Tree's Wabasso wells would represent a reasonable and beneficial use of the resource that did not appear to harm either the resource or existing users. It calculated the "crop requirement" for the golf courses on the basis of 135 acres. Testimony at the hearing established that the area required to be irrigated was only 70 acres. Consequently, the report's recommendation as to the annual water allocation for golf course irrigation was scaled down accordingly. Recommendations as to daily withdrawals were based upon the maximum billing by the City of Vero Beach for a 22-day period in January and February, 1975, plus a 20 percent allowance to provide a reasonable degree of operational flexibility. The conclusion of the staff that the withdrawal would not harm existing users is questionable in the light of the applicant's own hydrogeological study and testimony of its experts (Testimony of Winter, Exhibits 6,7,22). The Staff Report recommended that certain conditions be imposed upon any issuance of the requested permit. The following findings are made as to the reasonableness of such proposed conditions: Annual allocation of no more than 51.044 million gallons. FINDING: Reasonable. This permit shall expire 5 years after permit issuance. FINDING: Reasonable. The use may require reevaluation based upon developing needs of the area of withdrawal for higher priority uses of the resource. The total maximum monthly withdrawal from the two wells in Wabasso shall not exceed 6.931 million gallons. FINDING: Reasonable. The total daily withdrawal from the two wells in Wabasso shall not exceed 378,000 gallons. FINDING: Reasonable. Daily pumpage on a monthly basis shall be reported to the District during the following month. This data must be obtained through the use of an in line totalizing meter or meters at the well field. FINDING: Reasonable. Prior to the initiation of any pumping from the wells in Wabasso the permittee must survey all existing wells (with the owners' permission) located within 800 feet of each of these wells. Should it be determined that the permittee's pumping as recommended may adversely affect an existing well the permittee is to be held responsible for making timely corrective measures as deemed necessary at no expense to the owner, in order to preserve the water supply capability of that facility. A complete and detailed report of the survey and corrective measures taken by the permittee shall be submitted to the District. The District will then issue a notice authorizing the permittee to begin pumping as required. FINDING: Unreasonable. Although it is conceded by the applicants that adverse effects upon nearby wells may well occur, attempts to make determinations as to actual effects prior to full operation of Lost Tree's wells would only be speculative in nature. It is noteworthy in this regard that upon issuance of a temporary authorization to Lost Tree to withdraw water commencing in August, 1976, a similar precondition was imposed with a report of a survey and corrective measures taken to be submitted to the District prior to authorization to begin pumping. A cursory survey was performed by a representative of Lost Tree that consisted merely of attempting to locate surrounding wells by off-premises observation. No attempt was made to contact well owners or to obtain information as to the types of pumps on the wells. Such a survey is patently inadequate for the purposes desired by the District and it is considered impracticable and onerous to saddle the applicant with the burden of such a condition. Although withdrawals of water under the temporary permit commenced on September 18, 1976, and continued thereafter, there is no evidence that any complaints were registered by adjacent well owners as a result of the withdrawals (Testimony of Pearson, Exhibits 13, 14). For a period of 18 months after the first full week of operation in which no substantive complaints of adverse impact are received by the District, the permittee must assume full responsibility for taking the appropriate corrective to rectify any adverse impact their withdrawals create on any existing users within the area influenced by their withdrawal. Upon receiving a substantive complaint of adverse impact upon an existing user, the Executive Director of the District will issue a notice prohibiting any further withdrawals from the wells in Wabasso until corrective measures are taken by the permittee at no expense to the existing user, or until the permittee proves that their withdrawal is not the cause of the problem. The Executive Director of the District will issue a notice to resume withdrawals when the District has been satisfied that the situation is remedied. FINDING: Reasonable in part. The condition should be modified to extend the period of the permittee's responsibility for corrective action as to adverse impact on existing users to the entire life of the permit rather than for a period of only 18 months. Further, the District's prohibition of withdrawals after the receipt of a complaint is arbitrary and inconsistent with the method of administrative enforcement procedures as specified in Section 373.119(1), Florida Statutes. To help define the actual impact of the permittee's withdrawal a total of at least seven observation wells shall be installed. The observation wells shall be located between the permittee's wells and Indian River, two shall be located to the west and the remaining two shall be located either to the north or south of the permittee's wells. The locations and depths of these wells shall halve District concurrence. A continuous water level recording device shall be installed on one off these wells. FINDING: Reasonable. Although the installation and monitoring of a number of observation wells imposes a financial burden on the applicants, it is considered a proper requirement to assist in determining the impact of any withdrawal. The time for installation and specifications thereof should be set forth in any permit issued. Hydrographs from the recording device on one of the observation wells and from weekly hand measured water levels on the remaining observation wells shall be submitted to the District on a monthly basis. This data shall be submitted in the month following the period of record. All water level data shall be measured and recorded to the nearest hundredth of a foot and referenced to mean sea level. FINDING: Reasonable. By acceptance of this permit the permittee acknowledges that this permit confers no prior right to the permittee for the use of water in the amount allocated and for the purpose stated. FINDING: Unreasonable. The condition is ambiguous and involves legal aspects that are not proper for determination at this time. Any future application involving the use of the withdrawal facilities permitted herein, shall be considered as an application for a new use and it shall be reviewed accordingly. FINDING: Unreasonable. See comment in I above. All existing Floridan wells located on the applicant's properties must be abandoned in accordance with the current applicable standards of the Department of Environmental Regulation. Abandonment procedures must be carried out within 6 months of the date of issuance of this permit. FINDING: Unreasonable. The abandonment of existing Floridan wells involves subject matter not embraced within the application. An officer of the Lost Tree Village Corporation shall submit with each report required by the District a sworn and acknowledged affidavit that the report reflects the actual measurements or readings taken. FINDING: Reasonable. The Permittee shall obtain a water sample from a pumping well at the Wabasso well field site once a month, within five days of the end of the month. This sample shall be analyzed for chloride content, and the results reported to the District within 14 calendar days after collection. Should the District determine that a significant change has occurred in the chloride content of the water being withdrawn from the Wabasso well field, the District shall initiate a new review of the application. FINDING: Reasonable. Upon installation of the observation wells, a water sample shall be obtained from these wells and analyzed for the following parameters: Chloride Total Dissolved Solids Conductivity Sulfate Calcium Magnesium Sodium Bicarbonate This analysis shall be submitted to the District within 14 days after collection. During the last five days of the months of May and November of each year, during the duration of this permit, the permittee shall obtain one water sample from each of the installed observation wells. These samples shall be analyzed for Chloride content, and the results reported to the District within 14 days after collection. FINDING: Reasonable. If the permittee can demonstrate to the satisfaction of the District that the groundwater withdrawn by the south golf course well point system is no longer suitable for the irrigation of the golf course, the annual allocation shall be increased to 82.942 million gallons. FINDING: Unreasonable. Future needs should be the subject of modification of permit terms at an appropriate time, pursuant to section 373.239, F.S. An emergency authorization was issued to the applicants by the governing board of the District on August 30, 1976. This authorization contains certain special conditions including a requirement to conduct and submit a preauthorization survey and report concerning existing wells located within 800 feet of the applicant's wells. In addition, a condition of the authorization was that no withdrawals shall be made unless the City of Vero Beach had ordered the applicant to stop the use of water from its system for golf course irrigation. The evidence shows that neither of these conditions was met by the applicant, but yet withdrawals were made during the month of September, 1976 without District authorization (Testimony of Winter, Rearson, Exhibit 13). The applicant's disregard of these requirements indicates the need for a further special condition if a permit is granted, to ensure that adjacent land owners are protected in the event of adverse effects upon their water supply. To accomplish that, it is found that the following additional condition is reasonable and necessary: P. The Board shall require the applicant to furnish a bond in an appropriate amount, as authorized by Rule 16K-1.061, F.A.C. It is found that insufficient evidence has been presented to determine the merits of the request of the Town of Indian River Shores for an emergency water supply from the Wabasso wells.
Recommendation That a consumptive water use permit, with conditions as specified herein, be issued to applicant Lost Tree Village Corporation for the irrigation of its two golf courses at John's Island.

Findings Of Fact The Parties and the Property. The Respondent, Saddlebrook Resorts, Inc. (Saddlebrook), is a corporation organized and existing under the laws of Florida, and is wholly owned by the Dempsey family. Saddlebrook is located on approximately 480 acres in central Pasco County, east of I-75 and south of State Road 54. The Petitioner, Wiregrass Ranch, Inc. (Wiregrass) is a corporation organized and existing under the laws of Florida, and is wholly owned by the Porter family ("the Porters"). Wiregrass owns approximately 5,000 acres of property which extends from Saddlebrook west approximately one mile to State Road 581 and south for approximately four miles. The Respondent, the Southwest Florida Water Management District (SWFWMD), is a political subdivision created pursuant to Chapter 61-691, Laws of Florida, which exists and operates under the Water Resources Act, Fla. Stat., Ch. 373. SWFWMD is charged with regulating, among other things, surface water management systems in Pasco County. Saddlebrook discharges surface water onto Wiregrass at two locations on the southern and western boundaries of Saddlebrook, known as the south outfall and the west outfall. Saddlebrook's property is part of a drainage basin totalling approximately 1400 acres that contributes runoff to Wiregrass' property. Until approximately 1973, the Saddlebrook property was undeveloped and owned by the Porters. In approximately 1973, the Porters sold the Saddlebrook property to the Refram family, which began developing the property. In approximately 1979, Saddlebrook acquired the property from the Reframs. The Saddlebrook property includes residential development, a conference center, and golf course and tennis facilities. Wiregrass' property, which is largely undeveloped and used for ranching, consists of pine-palmetto flatwoods, wetland strands, isolated wetlands, and improved pastures. The Porters' Civil Action Against Saddlebrook. The Porters instituted a civil action against Saddlebrook, Porter, et al. v. Saddlebrook Resorts, Inc., Case No. CA 83-1860, in the Circuit Court of the Sixth Judicial District, Pasco County, complaining that post-development discharges from Saddlebrook exceed pre-development discharges. In the civil litigation, the Porters contended that Saddlebrook's peak flow discharges should be returned to pre-development, or 1973, levels. A primary purpose of Saddlebrook's proposed redesign is to return peak flow discharges to those levels that existed in 1973, in response to the Porters' complaints in the civil action. Saddlebrook's current surface water management system is deemed by SWFWMD to be in compliance with Rule 40D-4, and SWFWMD's regulations do not require redesign or modification of the current system. Prior to Saddlebrook's submission of its application, SWFWMD advised Saddlebrook that, because Rule 40D-4 became effective on October 1, 1984, SWFWMD considered that date to be the "pre-development" condition for purposes of evaluating Saddlebrook's discharges. Saddlebrook requested that SWFWMD evaluate its application using 1973 as the pre-development condition. SWFWMD advised Saddlebrook that it would apply 1973 as the pre-development condition if the Porters consented. By letter from the Porters' counsel to SWFWMD dated January 31, 1990, the Porters provided their express consent to SWFWMD's use of 1973 as the pre- development date for purposes of evaluating those discharges relevant to Saddlebrook's MSSW permit application. Saddlebrook's MSSW Permit Application. On or about February 8, 1990, Saddlebrook submitted its application for MSSW permit no. 497318.00, seeking SWFWMD's conceptual approval of the redesign of Saddlebrook's surface water management system. The proposed redesign calls for modification of most of the existing drainage control structures at Saddlebrook and installation of new control structures at several locations, including the south and west outfalls. After submission of its initial application, Saddlebrook made various subsequent submittals in response to SWFWMD requests for additional information. Saddlebrook's response to SWFWMD's requests culminated in final submittals on March 7, 1991 and April 5, 1991. In its various submittals, Saddlebrook provided, among other things, detailed descriptions of all proposed modifications to its drainage system, engineering reports, and computerized flood-routing analyses of runoff from Saddlebrook under pre-development (1973) and post-modification conditions. Saddlebrook provided all information requested, and SWFWMD thereafter deemed its application complete. SWFWMD's Review of Saddlebrook's Application. In the fifteen months following Saddlwbrook's initial February, 1990, submittal, SWFWMD conducted an intensive review of the application. During the course of this review, SWFWMD staff performed numerous field inspections, made an independent determination of all input data to the computer analyses of Saddlebrook's discharges, and made six separate formal requests for additional information. SWFWMD's requests for additional information required, among other things, that Saddlebrook modify various input data and rerun its computer analyses of discharges under the pre-development and post-modification conditions. In addition, SWFWMD required Saddlebrook to perform computer modelling analyses of discharges from Wiregrass' property onto the property of downstream landowners. Because, unlike the Porters, these downstream owners had not provided consent to use 1973 as the relevant pre-development date, SWFWMD required Saddlebrook to model this downstream discharge using a "pre- development" date of 1984. SWFWMD performed its standard review procedures in connection with Saddlebrooks' application. In addition, SWFWMD also performed its own computer-modelling analyses of Saddlebrook's discharges. This modelling was based on input data independently collected by SWFWMD staff in the field and from other sources. SWFWMD staff also met with the Porters' hydrologist, Dr. Gerald Seaburn, and thoroughly reviewed concerns he expressed in connection with Saddlebrook's application. In addressing these concerns, SWFWMD performed additional work, including conferring with an independent soils expert, performing additional field inspections, and modifying the SWFWMD computer modelling analyses based on alternative input parameters suggested by Dr. Seaburn. In reviewing Saddlebrook's application, SWFWMD applied the design and performance criteria set forth in its "Basis of Review for Surface Water Management Permit Applications" ("Basis of Review"), which is incorporated by reference in F.A.C. Rule Chapter 40D-4. Based upon its review of Saddlebrook's application, SWFWMD concluded that Saddlebrook had demonstrated compliance with the design and performance criteria set forth in SWFWMD's Basis of Review and the conditions for permit issuance under F.A.C. Rule 40D-4.301. By a Staff Report dated April 29, 1991, and Notice of Proposed Agency Action dated May 3, 1991, SWFWMD recommended approval of Saddlebrook's application. Compliance With SWFWMD Permitting Criteria. The design and performance criteria for MSSW permitting set forth in SWFWMD's Basis of Review fall into four categories: (1) water quantity, in terms of peak flow discharges for projects, like Saddlebrook's, located in open drainage basins; (2) flood protection; (3) water quality; and (4) wetlands impacts. Water Quantity. Under the Basis of Review's water quantity standards, SWFWMD requires that projected peak flow discharges during a 25-year, 24-hour storm event under the proposed system be reasonably similar to peak flow discharges under the pre- development condition. The evidence presented at the formal hearing demonstrated that Saddlebrook's application satisfies SWFWMD's water-quantity standards. This evidence demonstrated that peak flow discharges during a 25-year, 24-hour storm event under the proposed system will be less than, but reasonably similar to, pre-development (1973) peak flow discharges. The evidence presented at the formal hearing also demonstrated that, under the proposed system, peak flow discharges during a 25-year, 24-hour storm event from Wiregrass' property onto downstream landowners will be less than, but reasonably similar to, 1984 peak flow discharges. The evidence presented by Saddlebrook further demonstrated that storage will be increased under the proposed redesign versus the pre- development, 1973 condition. On Saddlebrook's property, there will be approximately 35 percent more storage than existed in 1973, and the total storage for Saddlebrook and the contributing drainage basin upstream of Saddlebrook will be increased by approximately 15 percent over that existing in 1973. Flood Protection. Under the flood-protection standards of the Basis of Review, SWFWMD requires that the applicant demonstrate that under the proposed condition the lower floor of all residential and other buildings on-site, and in areas affected by the site, will be above the 100-year flood elevation. SWFWMD also requires that there be no net encroachment into the flood plain, up to that encompassed by the 100-year event, which will adversely affect conveyance, storage, water quality or adjacent lands. The evidence presented at the formal hearing demonstrated that Saddlebrook's application satisfies SWFWMD's flood-protection standards. The testimony of Mr. Fuxan and Wiregrass' related exhibit, Ranch Ex. 35, purporting to show that in a 25-year, 24-hour storm Saddlebrook's proposed redesign will "flood the [Saddlebrook perimeter] roads and just sheet flow onto the Porter property" is not accurate. As part of its redesign, Saddlebrook will construct an additional berm along the southwestern and southern perimeters of its property. This berm will detain water on Saddlebrook's property during a 25-year, 24-hour storm event and prevent it from "sheet-flowing" onto the Wiregrass property. Water Quality. Under the water-quality standards of the Basis of Review, SWFWMD requires, for systems like Saddlebrook's involving wet detention and isolated wetlands, that the applicant provide sufficient storage to treat one inch of runoff from the basins contributing runoff to the site. This volume must be discharged in no less than 120 hours, with no more than one-half of the volume being discharged within the first 60 hours. The evidence presented at the formal hearing demonstrated that Saddlebrook's application satisfies SWFWMD's water-quality standards. Wetland Impacts. Under the wetland-impacts standards of the Basis of Review, SWFWMD requires that the applicant provide reasonable assurance that the proposed system will not adversely impact on-site and downstream wetlands. The evidence presented at the formal hearing demonstrated that Saddlebrook has provided reasonable assurance that the proposed redesign will cause no adverse impacts to on-site wetlands. Saddlebrook's proposed redesign will impact only approximately .167 acres of on-site wetlands, for which Saddlebrook will fully mitigate by creating .174 acres of forested wetlands and buffer area. The evidence presented at the formal hearing also demonstrated that Saddlebrook has provided reasonable assurance that the proposed redesign will cause no adverse impacts to off-site wetlands. Reasonable assurance that off- site wetlands will not be adversely impacted was demonstrated by, among other things, evidence establishing that: (1) discharge points will not change under the proposed condition; (2) discharge elevations will be reasonably similar under the proposed condition; (3) there will be no significant variation in the water fluctuations in the wetlands adjacent to the south and west outfalls as a result of the proposed condition; (4) the drainage basin areas will be reasonably similar under the proposed condition; and (5) the proposed redesign will satisfy SWFWMD's water quality requirements. Wiregrass' Petition. In its Petition for Formal Administrative Hearing, Wiregrass focused primarily on water quality issues and stormwater runoff rates (or peak flow discharges), alleging the following "ultimate facts" which it claimed "entitle [it] to relief": The application, as submitted, contains insufficient storage to meet water quality criteria. The application, as submitted, will result in storage volumes on the project site which will not be recovered within 72 hours [sic] as required by the DISTRICT criteria. The application, as submitted, contains calculations based on erroneous hydraulic gradients. The application, as submitted, will result in storage volumes insufficient to meet water quality criteria as required by DISTRICT criteria. Post development stormwater runoff rates are underestimated in the application, resulting in system design with insufficient retention storage capacity to meet the DISTRICT's water quantity criteria. The failure to store stormwater or irrigation runoff impacts the substantial interest of the RANCH in that it deprives it of groundwater resources necessary for the successful operation of the ranch. Further, the lack of storage of stormwater and irrigation water is a prohibited waste of the water resources. At the formal hearing, Wiregrass presented no evidence to support any of the foregoing allegations of its Petition. Objections Raised by Wiregrass At The Hearing. At the final hearing, Wiregrass' opposition to Saddlebrook's permit application focused on three different grounds: For purposes of evaluating peak flow discharges, SWFWMD does not have jurisdiction to use a pre-development date prior to October 1, 1984. Under F.A.C. Rule 40D-4.301(1)(i), which provides that an applicant must give reasonable assurance that the surface water management systems "is consistent with the requirements of other public agencies," SWFWMD must apply not only its own permitting criteria but also those of other governmental entities, including county planning ordinan Under F.A.C. Rule 40D-4.301(1)(b), which provides that a permit application must give reasonable assurances that the surface water management system "will not cause adverse water . . . quantity impacts", SWFWMD must consider whether the annual volume of runoff will increase as a result of the proposed surface water management system. None of the foregoing objections was raised in Wiregrass' Petition as a basis for denying Saddlebrook's application. (Annual volume was alluded to in the Petition only as being pertinent to the question of Wiregrass' "substantial interest" for purposes of standing.) In any event, for the reasons set forth below, each of these objections was refuted by the evidence presented at the formal hearing. The 1973 Pre-Development Date. In their civil action against Saddlebrook, the Porters took the position that Saddlebrook's surface water management system should be redesigned so that discharges approximate those levels existing in 1973, before development of the Saddlebrook property. Dr. Gerald Seaburn, a hydrologist retained by the Porters, testified in the civil action that 1973 is the appropriate pre-development date for purposes of evaluating Saddlebrook's peak flow discharges. David Fuxan, a civil engineer retained by the Porters, took the position in the civil action that Saddlebrook should modify its surface water management system so as to return peak flow discharges to 1973 levels. At the formal hearing in this proceeding, Mr. Fuxan testified that it is still his position that Saddlebrook should modify its surface water management system so as to return peak flow discharges to 1973 levels. By letter from the Porters' counsel to SWFWMD dated January 31, 1990, the Porters provided their express consent to SWFWMD's use of 1973 as the pre- development date for evaluating those discharges relevant to Saddlebrook's MSSW permit application. Use of a 1984 "pre-development" date would prevent Saddlebrook from making the modifications the Porters claim in the civil litigation that it must make. Saddlebrook's existing system, about which the Porters complain in the civil litigation, is in all material respects the same system that was in place on October 1, 1984. Use of this existing system as the benchmark of comparison for attenuation of peak flows, therefore, would mean that substantial modifications to the existing system could not be made without substantially increasing retention storage on Saddlebrook. Substantially increasing retention storage on Saddlebrook is not possible due to the high water table and proximity of the lower aquifer. See Finding of Fact 70, below. In addition, a primary claim of the Porters in the civil action is that duration of flow under Saddlebrook's existing system exceeds 1973 levels and has resulted in expanded wetlands on the Porter property. But duration of flow and peak flow discharges are inversely related: duration of flow can be decreased only if peak flow discharges are increased. Accordingly, the only way that Saddlebrook can reduce the duration of flow onto Wiregrass to 1973 levels, as the Porters have demanded, other than increasing retention storage on Saddlebrook, is to return peak flow discharges to 1973 levels. Other Governmental Agencies' Requirements. F.A.C. Rule 40D-4.301(1)(i) provides that a permit applicant must give reasonable assurance that the surface water management system "is consistent with the requirements of other public agencies." SWFWMD has consistently interpreted this provision to be "advisory", i.e., to apprise applicants that they must also comply with other applicable laws and that issuance of an MSSW permit by the District does not relieve them of the responsibility to obtain all necessary local and other permits. SWFWMD's long-standing and consistently-applied interpretation and practice is not to require applicants to prove compliance with the regulations of other govermental agencies in order to obtain an MSSW permit. There are two primary reasons for this interpretation and practice. First, the Southwest Florida Water Management District includes 16 counties and 96 municipalities. In addition, other state and various federal agencies have jurisdiction within its territory. It is impracticable for SWFWMD to become familiar with, and to apply, the permitting and other regulations of more than 100 other agencies. Second, SWFWMD has concluded that, under Part 4 of Secton 373 of the Flordia Statutes, it does not have authority to deny a permit application based on its interpretation of another governmental agency's regulations. In any event, the evidence demonstrates that Saddlebrook has provided reasonable assurance that the proposed redesign will be "consistent with the requirements of other public agencies" as provided in F.A.C. Rule 40D- 4.301(1)(i). Limiting Condition No. 3 of the proposed permit requires that Saddlebrook must comply with Pasco County and other local requirements: The Permittee shall comply with all applicable local subdivision regulations and other local requirements. In addition the permittee shall obtain all necessary Federal, State, local and special district authorizations prior to the start of any construction or alteration of works authorized by this permit. In addition, Standard Condition No.3 ensures that SWFWMD approval will not supersede any separate permitting or other requirements imposed by Pasco County: The issuance of this permit does not . . . authorize any . . . infringement of federal, state or local laws or regulations. (Emphasis added.) Finally, the Pasco County ordinance upon which Wiregrass relies imposes requirements that are in substance identical to SWFWMD's with respect to MSSW permit applications. Saddlebrook's compliance with SWFWMD's regulations likewise would satisfy the substance of the requirements of the county ordinance. Annual Volume of Runoff. F.A.C. Rule 40D-4 (incorporating the Basis of Review) does not address, and SWFWMD does not regulate, the annual volume of runoff in open drainage basins. If annual volume of runoff is relevant under Rule 40D-4.301, as Wiregrass contends, that rule requires only that the applicant provide reasonable assurance that "the surface water management system" will not cause adverse quantity impacts. Saddlebrook's existing surface water management system has not caused a significant increase in the annual volume of runoff onto Wiregrass' property. The increase in the annual volume of runoff from Saddlebrook that has occurred over the pre-development 1973 condition has resulted from the urbanization of Saddlebrook's property. The increase in the annual volume of runoff from Saddlebrook over that existing prior to development (1973) is approximately 3.4 inches. This increase is only a small fraction of the natural year-to-year variation in runoff resulting from differences in rainfall alone. Rainfall can vary up to 30 inches on an annual basis, from 40 to 70 inches per year. The resulting year-to-year variations in runoff can total as much as 20 inches. The approximately 3.4 inches increase in the annual volume of runoff from Saddlebrook due to urbanization has caused no adverse impact to Wiregrass. The natural drainage system on the Wiregrass property has in the past and throughout its history received and handled increases in the annual volume of runoff of up to 20 inches due to rainfall differences. Such increases simply flow through Wiregrass' property. Of the approximately 3.4 inch increase in annual runoff due to urbanization, only approximately one-third of an inch is due to the filling in of bayheads by Saddlebrook's prior owner. This increase is insignificant and has not caused a substantial adverse impact to Wiregrass. Any reduction of storage resulting from the filling of bayheads will be more than compensated for under the proposed redesign. Storage on Saddlebrook's property will be increased by approximately 35 percent under the proposed condition over that existing in 1973, before the bayheads were filled. In open drainage basins, like Saddlebrook's, downstream flooding is a function of the rate of peak flow of discharge, not the annual volume of runoff. This is one of the reasons why, in the case of open drainage basins, SWFWMD regulates peak flow discharges and not the annual volume of runoff. Because Saddlebrook's proposed redesign will attenuate peak flow discharges to those levels that existed in the pre-devlopment 1973 condition, Saddlebrook has provided reasonable assurance that there will not be increased flooding on Wiregrass' property in the future. The evidence does not establish that Wiregrass has suffered, or will suffer, any adverse impact due to an increase in the annual volume of runoff from Saddlebrook as a result of the design, or redesign, of the system, or as a result of urbanization, or otherwise. It is not possible to design a surface water management system at Saddlebrook that would reduce the annual volume of runoff. Such a system, which involves the percolation of surface water from retention ponds into a deeper, aquifer system, requires a deep water table. At Saddlebrook, the water table is near the ground surface. As a result, it is not possible to store a significant quantity of water in retention ponds between storm events. In addition, the water levels in the deeper and the shallower aquifer systems at Saddlebrook are approximately the same and, therefore, there is insufficient hydraulic pressure to push the water through the confining layer between the two systems and into the deeper aquifer system.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Southwest Florida Water Management District enter a final order granting Saddlebrook's application for surface water management permit no. 497318.00, subject to the terms and conditions in the SWFWMD Staff Report. RECOMMENDED this 31st day of March, 1992, in Tallahassee, Florida. J. LAWRENCE JOHNSTON 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 31st day of March, 1992. APPENDIX TO RECOMMENDED ORDER, CASE NO. 91-3658 To comply with the requirements of Section 120.59(2), Fla. Stat. (1991), the following rulings are made on the parties' proposed findings of fact: Petitioner's Proposed Findings of Fact. 1.-4. Accepted and incorporated. Rejected as not proven and contrary to the greater weight of the evidence. Accepted and incorporated to the extent not subordinate or unnecessary. 7.-9. Rejected as not proven and contrary to the greater weight of the evidence. First sentence, accepted. Second sentence, rejected as not proven and contrary to the greater weight of the evidence. Accepted but not necessary. 12.-13. Rejected as not proven and contrary to the greater weight of the evidence. Accepted but not necessary. The extent of the wetland expansion is rejected as not proven and contrary to the greater weight of the evidence. The rest is accepted. However, the increased volume is due in large part to urbanization, not to the surface water management system. It also is due in part to alterations to the property done by the Porters. Accepted but subordinate and unnecessary. Accepted. However, this would occur only during a 25-year, 24-hour storm event, and there was no evidence that one has occurred or, if it has, whether Mr. Porter was there to observe it. 18.-20. Accepted but subordinate and unnecessary. Characterization "much of" is rejected as not proven and contrary to the greater weight of the evidence. Otherwise, accepted but subordinate and unnecessary. Accepted and incorporated. Rejected as not proven and contrary to the greater weight of the evidence. Rejected as not proven and contrary to the greater weight of the evidence. Rejected as not proven and contrary to the greater weight of the evidence that lichen lines, by themselves, are ordinarily are sufficient to set jurisdictional lines. 26.-29. Rejected as not proven and contrary to the greater weight of the evidence. Even if it were proven that the wetlands had expanded, it was not proven, and is contrary to the greater weight of the evidence, that Saddlebrook (and, especially, Saddlebrook's surface water management system) caused the expansion. First sentence, accepted but cumulative. The rest is rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. In any event, both factors are undeniably significant. 32.-34. Rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Rejected as not proven and contrary to the greater weight of the evidence. 39.-41. Rejected as not proven and contrary to the greater weight of the evidence that SWFWMD does not apply it. The evidence was that SWFWMD interprets it differently than Wiregrass proposes and applies its own interpretation. Under the SWFWMD interpretation, the permit conditions requiring compliance with other legal requirements constitute the necessary "reasonable assurance." In addition, SWFWMD's review and evaluation is not complete until this formal administrative proceeding is completed, and the Pasco County ordinance has been considered as part of this proceeding. Rejected as not proven and contrary to the greater weight of the evidence. Again, SWFWMD's review and evaluation is not complete until this formal administrative proceeding is completed, and annual volume has been considered as part of this proceeding. That consideration has affirmed SWFWMD's position that, at least in this case, the proposed stormwater management system does not cause an increase in annual volume that would result in denial of the application. Accepted but subordinate and unnecessary. Rejected as not proven and contrary to the greater weight of the evidence. First sentence, accepted (although the characterization "far exceed" is imprecise) and incorporated. Second sentence, rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary that no "stipulation" was entered into. But the evidence is clear that Wiregrass, Saddlebrook and SWFWMD all agreed to the use of 1973 as the point of comparison for peak flow discharges. Rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Respondents' Proposed Findings of Fact. The proposed findings of fact contained in the Proposed Recommended Order of Respondents Saddlebrook Resorts, Inc., and Southwest Florida Water Management District are accepted and incorporated to the extent not subordinate or unnecessary.

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. DONE AND ENTERED this 17th day of October, 2001, in Tallahassee, Leon County, Florida. __________________________________ J.
