The Issue The issue in this case is whether Respondent Laniger Enterprises of America, Inc. (Laniger), is liable to Petitioner Department of Environmental Protection (Department) for penalties and costs for the violations alleged in the Department's Notice of Violation, Orders for Corrective Action, and Administrative Penalty Assessment (NOV).
Findings Of Fact The Parties The Department is the administrative agency of the State of Florida having the power and duty to protect Florida's air and water resources and to administer and enforce the provisions of Chapter 403, Florida Statutes, and the rules promulgated in Florida Administrative Code Title 62. Laniger is a Florida corporation that owns and operates the WWTP that is the subject of this case, located at 1662 Northeast Dixie Highway, Jensen Beach, Martin County, Florida. The WWTP is referred to in the Department permit documents as the Beacon 21 WWTP. The WWTP Laniger acquired the WWTP in 1988 in a foreclosure action. At that time, the WWTP was in a "dilapidated" condition and was operating under a consent order with the Department. After acquiring the WWTP, Laniger brought it into compliance with the Department's requirements. Laniger's WWTP is commonly referred to as a "package plant."3 The WWTP's treatment processes are extended aeration, chlorination, and effluent disposal to percolation ponds. The WWTP does not have a direct discharge to surface water. It was permitted to treat 99,000 gallons per day (gpd) of wastewater. Its average daily flow during the past year was about 56,000 gallons. The east side of the WWTP site is adjacent to Warner Creek. On the north side of the WWTP site, an earthen berm separates the WWTP's percolation ponds from a drainage ditch that connects to Warner Creek. Warner Creek is a tributary to the St. Lucie River. The St. Lucie River is part of the Indian River Lagoon System. The Indian River Lagoon Act In 1989, the St. Johns River Water Management District and the South Florida Water Management District jointly produced a Surface Water Improvement and Management (SWIM) Plan for the Indian River Lagoon System ("the lagoon system"). For the purpose of the planning effort, the lagoon system was defined as composed of Mosquito Lagoon, Indian River Lagoon, and Banana River Lagoon. It extends from Ponce de Leon Inlet in Volusia County to Jupiter Inlet in Palm Beach County, a distance of 155 miles. The SWIM Plan identified high levels of nutrients as a major problem affecting the water quality of the lagoon system. Domestic wastewater was identified as the major source of the nutrients. The SWIM Plan designated 12 problem areas within the lagoon system and targeted these areas for "research, restoration and conservation projects under the SWIM programs." Department Exhibit 2 at 11-13. Neither Warner Creek nor the St. Lucie River area near Laniger's WWTP is within any of the 12 problem areas identified in the SWIM Plan. With regard to package plants, the SWIM Plan stated: There are numerous, privately operated, "package" domestic WWTPs which discharge indirectly or directly to the lagoon. These facilities are a continual threat to water quality because of intermittent treatment process failure, seepage to the lagoon from effluent containment areas, or overflow to the lagoon during storm events. Additionally, because of the large number of "package" plants and the lack of enforcement staff, these facilities are not inspected or monitored as regularly as they should be. Where possible, such plants should be phased out and replaced with centralized sewage collection and treatment facilities. Department Exhibit 2, at 64. In 1990, the Legislature passed the Indian River Lagoon Act, Chapter 90-262, Laws of Florida. Section 1 of the Act defined the Indian River Lagoon System as including the same water bodies as described in the SWIM Plan, and their tributaries. Section 4 of the Act provided: Before July 1, 1991, the Department of Environmental Regulation shall identify areas served by package sewage treatment plants which are considered a threat to the water quality of the Indian River Lagoon System. In response to this legislative directive, the Department issued a report in July 1991, entitled "Indian River Lagoon System: Water Quality Threats from Package Wastewater Treatment Plants." The 1991 report found 322 package plants operating within the lagoon system and identified 155 plants as threats to water quality. The 1991 report described the criteria the Department used to determine which package plants were threats: Facilities that have direct discharges to the system were considered threats. Facilities with percolation ponds, absorption fields, or other sub-surface disposal; systems located within 100 feet of the shoreline or within 100 feet of any canal or drainage ditch that discharges or may discharge to the lagoon system during wet periods were considered threats. * * * Facilities with percolation ponds, absorption fields, or other sub-surface disposal systems located more than 100 feet from surface water bodies in the system were evaluated case-by-case based on [operating history, inspection reports, level of treatment, and facility reliability]. Laniger's package plant was listed in the 1991 report as a threat to the water quality of the lagoon system because it was within 100 feet of Warner Creek and the drainage ditch that connects to Warner Creek. The Department notified Laniger that its WWTP was listed as a threat to the water quality of the lagoon system soon after the 1991 report was issued. The Department's 1991 report concluded that the solution for package plants threats was to replace them with centralized sewage collection and treatment facilities. To date, over 90 of the package plants identified in the Department's 1991 report as threats to the water quality of the lagoon system have been connected to centralized sewage collection and treatment systems. The 1999 Permit and Administrative Order On August 26, 1999, the Department issued Domestic Wastewater Facility Permit No. FLA013879 to Laniger for the operation of its WWTP. Attached to and incorporated into Laniger's 1999 permit was Administrative Order No. AO 99-008- DW43SED. The administrative order indicates it was issued pursuant to Section 403.088(2)(f), Florida Statutes. That statute pertains to discharges that "will not meet permit conditions or applicable statutes and rules" and requires that the permit for such a discharge be accompanied by an order establishing a schedule for achieving compliance. The administrative order contains a finding that the Beacon 21 WWTP is a threat to the water quality of the lagoon system and that the WWTP "has not provided reasonable assurance . . . that operation of the facility will not cause pollution in contravention of chapter 403, F.S., and Chapter [sic] 62-610.850 of the Florida Administrative Code." The cited rule provides that "land application projects shall not cause or contribute to violations of water quality standards in surface waters." Most of the parties' evidence and argument was directed to the following requirements of the administrative order: Beacon 21 WWTP shall connect to the centralized wastewater collection and treatment within 150 days of its availability and properly abandoned facility [sic] or provide reasonable assurance in accordance with Chapter 62-620.320(1) of the Florida Administrative Code that continued operation of the wastewater facility is not a threat to the water quality of the Indian River Lagoon System and will not cause pollution in contravention of chapter 403, F.S. and Chapter 62-610.850 of the Florida Administrative Code. * * * (3) Beacon 21 WWTP shall provide this office with semi annual reports outlining progress toward compliance with the time frames specified in paragraph 1 of this section, beginning on the issuance date of permit number FLA013879-002-DW3P. The administrative order contained a "Notice of Rights" which informed Laniger of the procedures that had to be followed to challenge the administrative order. Laniger did not challenge the administrative order. As a result of an unrelated enforcement action taken by the Department against Martin County, and in lieu of a monetary penalty, Martin County agreed to extend a force main from its centralized sewage collection and treatment facility so that the Laniger WWTP could be connected. The extension of the force main was completed in April 2003. The force main was not extended to the boundary of the Laniger WWTP site. The force main terminates approximately 150 feet north of the Laniger WWTP site and is separated from the WWTP site by a railroad. Correspondence Regarding Compliance Issues On August 21, 2001, following an inspection of the Laniger WWTP, the Department sent Laniger a letter that identified some deficiencies, one of which was Laniger's failure to submit the semi-annual progress reports required by the administrative order. Reginald Burge, president of Laniger and owner of the WWTP, responded by letter to William Thiel of the Department, stating that, "All reports were sent to the West Palm Beach office. Copies are attached." Mr. Thiel testified that the progress reports were not attached to Laniger's letter and he informed Laniger that the reports were not attached. Mr. Burge testified that he subsequently hand-delivered the reports. At the hearing, it was disclosed that Laniger believed its semi-annual groundwater monitoring reports satisfied the requirement for progress reports and it was the monitoring reports that Mr. Burge was referring to in his correspondence and which he hand-delivered to the Department. Laniger's position in this regard, however, was not made clear in its correspondence to the Department and the Department apparently never understood Laniger's position until after issuance of the NOV. On April 10, 2003, the Department notified Laniger by letter that a centralized wastewater collection and treatment system "is now available for the connection of Beacon 21." In the notification letter, the Department reminded Laniger of the requirement of the administrative order to connect within 150 days of availability. On May 9, 2003, the Department received a response from Laniger's attorney, stating that the administrative order allowed Laniger, as an alternative to connecting to the centralized wastewater collection and treatment system, to provide reasonable assurance that the WWTP was not a threat to the water quality of the lagoon system, and Laniger had provided such reasonable assurance. It was also stated in the letter from Laniger's attorney that "due to the location of Martin County's wastewater facilities, such facilities are not available as that term is defined in the [administrative] Order."4 On May 29, 2003, the Department replied, pointing out that the administrative order had found that reasonable assurance was not provided at the time of the issuance of the permit in 1999, and Laniger had made no "improvements or upgrades to the facility." The Department also reiterated that the progress reports had not been submitted. On September 29, 2003, the Department issued a formal Warning Letter to Laniger for failure to connect to the Martin County force main and for not providing reasonable assurance that the WWTP will not cause pollution in contravention of Chapter 403, Florida Statutes. The progress reports were not mentioned in the Warning Letter. The Department took no further formal action until it issued the NOV in August 2005. Count I: Failure to Timely File for Permit Renewal and Operating Without a Permit Count I of the NOV alleges that Laniger failed to submit its permit renewal application at least 180 days prior to the expiration of the 1999 permit, failed to obtain renewal of its permit, and is operating the WWTP without a valid permit. The date that was 180 days before the expiration of the 1999 permit was on or about February 27, 2004. Laniger did not submit its permit renewal application until February 15, 2005. In an "enforcement meeting" between Laniger and the Department following the issuance of the warning letter in September 2003, the Department told Laniger that it would not renew Laniger's WWTP permit. It was not established in the record whether this enforcement meeting took place before or after February 27, 2004. When Laniger filed its permit renewal application in February 2005, the Department offered to send the application back so Laniger would not "waste" the filing fee, because the Department knew it was not going to approve the application. Laniger requested that the Department to act on the permit application, and the Department denied the application on April 6, 2005. The Department's Notice of Permit Denial stated that the permit was denied because Laniger had not connected to the available centralized wastewater collection and treatment system nor provided reasonable assurance that the WWTP "is not impacting water quality within the Indian River Lagoon System." Laniger filed a petition challenging the permit denial and that petition is the subject of DOAH Case 05-1599, which was consolidated for hearing with this enforcement case. Laniger's permit expired on August 25, 2004. Laniger has operated the plant continuously since the permit expired. Count II: Failure to Submit Progress Reports Count II of the NOV alleges that Laniger failed to comply with the requirement of the administrative order to provide the Department with semi-annual reports of Laniger's progress toward connecting to a centralized sewage collection and treatment facility or providing reasonable assurances that continued operation of the WWTP would not be a threat to the water quality of the lagoon system. Laniger maintains that its groundwater monitoring reports satisfied the requirement for the semi-annual progress reports because they showed that the WWTP was meeting applicable water quality standards. The requirement for groundwater monitoring reports was set forth in a separate section of Laniger's permit from the requirement to provide the semi-annual progress reports. The monitoring reports were for the purpose of demonstrating whether the WWTP was violating drinking water quality standards in the groundwater beneath the WWTP site. They served a different purpose than the progress reports, which were to describe steps taken by Laniger to connect to a centralized sewage collection and treatment facility. Laniger's submittal of the groundwater monitoring reports did not satisfy the requirement for submitting semi-annual progress reports. There was testimony presented by the Department to suggest that it believed the semi-annual progress reports were also applicable to Laniger's demonstration of reasonable assurances that the WWTP was not a threat to the water quality of the lagoon system. However, the progress reports were for the express purpose of "outlining progress toward compliance with the time frames specified in paragraph 1." (emphasis added) The only time frame mentioned in paragraph 1 of the administrative order is connection to an available centralized wastewater collection and treatment facility "within 150 days of its availability." There is no reasonable construction of the wording of this condition that would require Laniger to submit semi-annual progress reports related to reasonable assurances that the WWTP is not a threat to the water quality of the lagoon system. Count III: Department Costs In Count III of the NOV, the Department demands $1,000.00 for its reasonable costs incurred in this case. Laniger did not dispute the Department's costs.
The Issue Did Respondents violate the provisions of Rules 62-550.518(3), 62-555.320(4)(8), 62-560.410(2)(c), 62555.350(2), and 62-555.345, Florida Administrative Code, as alleged in the Notice of Violation and Orders for Corrective Action, Case Nos. 96-653PW2442B and 96- 653PW2442C dated June 9, 1997?
Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant findings of fact are made: At all times pertinent to this proceeding, the Department, through the Polk County Health Department, under the authority of an Interagency Agreement with the Department of Environmental Protection, was the agency of the State of Florida charged with the responsibility for inspecting and clearing Public Water Systems in Polk County Florida under Section 403.121, Florida Statutes. SDS Properties Investors Group, Inc. (SDS) is a Florida corporation authorized to do business as Budget Motel. SDS is owned by Shaikh. Sanitary surveys are conducted by the Department every three years and include the inspection of Public Water Systems (PWS) . On January 26, 1996, the Department conducted a routine sanitary survey of Budget Motel (Budget) located at 1418 Highway 17 South, Lake Wales, Florida, which should have included Budget's public water system, PWS 6532442. However, Polk County's inspector, Henry Tagioff, was shown a well, by a Budget employee, that was located on the adjacent property owned by Smokey's Mobile Home Park (Smokey's) and not a part of Budget's water system. Tagioff was not aware that the well he inspected was owned by Smokey's and not on Budget's property. During the inspection, Tagioff noted several violations and advised the Budget employee that Tagioff needed to discuss these violations with Shaikh. On January 29, 1996, Tagioff and Lee Forgey, another Polk County employee, met with Shaikh to discuss the violations noted by Tagioff on January 26, 1996. During this meeting, Shaikh, Tagioff, and Forgey discussed the violations previously found by Tagioff on January 26, 1996, concerning the well on Smokey's property. At no time during this meeting did Shaikh advise Tagioff or Forgey that neither he nor Budget own the well under discussion. The record is not clear, but sometime between January and May 1996, Budget's well had collapsed and was not useable. Subsequent to Budget's well collapsing, Shaikh contracted with George Dunham, after obtaining Smokey's permission, to connect Budget's water system (PWS6532442) to Smokey's well. At the time of connecting Budget's water system to Smokey's well, Dunham advised Shaikh that this was only a temporary solution and gave Shaikh a proposal for a new well since Budget's old well could not be repaired. On May 2, 1996, Tagioff made a reinspection of Budget's water system and found that Budget's well had collapsed and was inoperable, and that Budget had connected to Smokey's well to furnish water to the motel and its guests. Tagioff advised Shaikh that Budget would need a new well since its old well was inoperable and the connection to Smokey's well was only temporary. On May 21, 1996, Mark Fallah, a Polk County employee, conducted a site inspection and prepared a report for use in connection with Budget's application with Southwest Florida Water Management District (SWFWMD) for a new well permit. In connection with Fallah's site inspection and report, the Department advised Shaikh by letter dated May 21, 1996, of certain things concerning the new well that had to be completed prior to placing the well into public use. The letter provides in pertinent part as follows: Upon completion of the drilling and the verification of the grouting procedure by the Water Management District, the following items, as required by Chapters 62-555 and 62550 of the Florida Administrative Code, are to be completed prior to this water system being placed into public use. * * * 2. A continuous chlorination unit that is electrically interlocked with the well pump circuit. * * * A flow measuring device is required on all Non-Community Water Systems. A copy of the well completion report must be furnished to this office by the well driller within thirty (30) days after the well installation. Bacteriological clearance of the well must be performed by submitting twenty (20) consecutive water samples for analysis to an HRS certified laboratory. A maximum of two (2) samples per day taken at least six hours apart may be collected. Additional samples may be required until twenty (20) consecutive satisfactory samples are received. * * * After the well and plant construction is completed, contact our office for an inspection so that written clearance can be issued. It is prohibited for any Public water system to be placed into use without clearance being issued from this department. (Emphasis Furnished). SWFWMD approved Budget's new well application and issued Budget Permit No. 579811.01 for drilling a new well. However, upon completion of the new well, there were certain conditions that had to be met as indicated in the letter from the Department dated May 21, 1996. On May 31, 1996, and July 10, 1996, Fallah inspected Budget's new water system for compliance and, on both occasions, found that Budget had failed to install the chlorination unit, the flow meter, and had not submitted a well completion report or bacteriological samples. On July 15, 1996, the Department issued a Warning Notice to Shaikh advising him that the system could not be used until approved by the Department. For enforcement purposes, the file was transferred to Lewis Taylor, enforcement officer for drinking water systems for Polk County. On November 14, 1996, Taylor conducted an inspection of Budget's water system and reported that: (1) Budget's well had been placed into service without approval from the Department; (2) there was no chlorinator in operation; (3) there was no flow meter; (4) the Department had not received any bacteriological samples since November 1995; (5) there was no certified operator servicing the motel's water system; and (6) Budget had not provided public notice to its customers of its failure to monitor its drinking water. A second Warning Notice was issued by the Department and furnished to Shaikh on November 22, 19-96, which in substance advised Shaikh that Budget was in violation of Rules 62-550 and 62- 555, Florida Administrative Code, for its: (1) failure to obtain the Department's clearance before placing its new well in service; (2) failure to provide quarterly bacteriological samples; (3) failure to maintain proper chlorine residual in the water system; failure to provide a flow meter in the water system; (5) failure to provide public notification to its customers that its water system had failed to comply with Rule 62-550, Florida Administrative Code; and (6) failure to provide the Department with verification of Budget retaining a certified operator to oversee the operation and maintenance of its water system. On March 3, 1997, Tagioff and John GoPaul, US Environmental Agency, inspected Budget's water system and found that: (1) there was no chlorine residual in the system; (2) the chlorination unit located at the motel was not in use; (3) there was no flow meter within the system; (4) no quarterly bacteriological samples had been furnished to the Department; and the well had not been cleared for use by the Department. Based on the testimony of Lewis Taylor which I find credible, the Department has expended the following in the inspection of Budget's water system: (1) 20.25 hours of professional time at a rate of $30.00 per hour for a total of $607.50; (2) three hours of clerical time at a rate of $15.00 per hour for a total of $45.00; and (3) $27.00 in travel costs and postage. The total amount expended in the inspection of this water system by the Department was $679.50.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Department enter a final order finding Respondents guilty of the violations as charged and requiring Respondents to comply with the Orders for Corrective Action as set out in the Notice of Violation and Orders of Corrective Action in Case Nos. 96-653PW2442B and 96-653PW2442C. It is further recommended that Respondents be required to pay the costs and expenses of investigating the violations and prosecuting this matter in the amount of $679.50.

The Issue The issues set forth in DOAH Case No. 84-3810 concern the question of whether the State of Florida, Department of Environmental Regulation (DER) should issue a permit to Homer Smith d/b/a Homer Smith Seafood (Homer Smith) to construct a wastewater treatment facility which is constituted of a screening mechanism, dissolved air flotation treatment system, sludge drying bed, pumping station and subaqueous pipeline. In the related action, DOAH Case No. 84-3811, the question is raised whether DER should issue a dredge and fill permit to Homer Smith for the installation of the aforementioned pipeline along submerged lands in Trout Creek, Palmo Cove and the St. Johns River.
Findings Of Fact Introduction and Background In 1982, Homer Smith, under the name of Homer Smith Seafood, established a calico scallop processing facility in the vicinity of the intersection of State Road 13 and Trout Creek in St. Johns County, Florida. From that point forward, Smith has owned and operated the processing plant. His plant adjoins Trout Creek, which is a tributary to the St. Johns River. Both Trout Creek and the St. Johns River are tidally influenced waters that are classified as Class III surface waters under Rule 17-3.161, Florida Administrative Code. The processing undertaken by Smith's operation at Trout Creek contemplates the preparation of the scallops for human consumption. In particular, it involves the purchase of calico scallops from Port Canaveral, Florida, after which the scallops are transported by refrigerated trucks to the processing plant. They are then unloaded into metal hoppers and directed into rotating tumblers which separate out the scallops from sand, mud and other extraneous material. The scallops are placed in a steam tumbler that removes the shells and then passed through a flow tank that washes away sand, grit and shell particles. The scallops are next passed through eviscerators. These eviscerators are long tubes of aluminum with roughened surfaces that pull the viscera off of the scallops. The detached scallops are then sent along a conveyor belt, with scallops in need of further cleaning being picked out and sent to a second eviscerator. The eviscerated scallops are then chilled and packed for marketing. It is the viscera and wastewater associated with this material that is the subject of permitting. Homer Smith is one of about six automated scallop processing plants located in Florida. Two other plants are within St. Johns County, on the San Sebastian River in St. Augustine, Florida. Three other plants are located in Port Canaveral, Florida. When Smith commenced his operation of the scallop processing plant in the summer of 1982, he discharged the scallop processing wastewater into an area described as a swamp with an associated canal which connected to Trout Creek. By the fall of 1982, Smith had been told by representatives of the Department of Environmental Regulation that to operate his facility with the discharge would require a permit(s) from DER. At the time of this discussion, automatic scallop processing was an industry for which appropriate wastewater treatment alternatives had not been specifically identified by the Department of Environmental Regulation or the United States Environmental Protection Agency. This was and continues to be the case as it relates to the promulgation of technology-based effluent limitations designed for calico scallop processors. This circumstance is unlike the situation for most other industries for which DER has established technology-based effluent limitations. To rectify this situation, Florida Laws 85-231 at Section 403.0861, Florida Statutes, requires DER to promulgate technology-based effluent limitations for calico scallop processors by December 1986. In the interim, consideration of any permits that might be afforded the calico scallop processors by the exercise of DER's regulatory authority must be done on a case-by-case basis, when examining the question of technology-based effluent limitations. DER sent a warning letter to Smith on April 20, 1983, informing the processor that discarding its wastewater into Trout Creek without a DER permit constituted a violation of state law. After the warning letter, scallop harvesting declined to the point that by mid-June of 1983 the plant had closed down, and it did not reopen until the middle part of September 1983. Upon the recommencement of operations, DER issued a cease and desist notice and ordered Smith to quit the discharge of wastewater from the facility into Trout Creek. On the topic of the cease and desist, through litigation, Smith has been allowed the right to conduct interim operation of his business which involves direct discharge of wastewater into Trout Creek, pending assessment of wastewater treatment alternatives and pursuit of appropriate DER permits. 1/ When Smith filed for permits on April 10, 1984, he asked for permission to dredge and fill and for construction rights pertaining to industrial wastewater discharge into the St. Johns River. The application of April 10, 1984, involved the installation of a wastewater treatment system and an associated outfall pipeline to transport treated wastewater to the St. Johns River from the plant location. This system would utilize a series of settling tanks and a shell-filter lagoon as the principal wastewater treatment. DER, following evaluation, gave notice in October 1984 of its intent to issue permits related to dredge and fill and the construction of the wastewater treatment facility. In the face of that notification, the present Petitioners offered a timely challenge to the issuance of any DER permits. In considering treatment alternatives, Homer Smith had employed various consultants and discovered that treatment beyond coarse screening had not been attempted in processing calico scallop wastewater. Those consultants were of the opinion that conventional treatment methods such as clarification, sand filtration, vortex separation, breakpoint chlorination, polymers and spray irrigation were of limited viability due to the inability to remove key constituents within the waste stream or based upon certain operational difficulties that they thought would be experienced in attempting those methods of treatment. As envisioned by the April 10, 1984, application for permit, interim treatment of the wastewater was provided by the use of a series of settling tanks and a shell-filter lagoon, within which system adjustments were made to the delivery of wastewater treatment. The April 10, 1984, permit application by Smith did not envision any chemical treatment of the wastewater aside from that which might occur in association with the settling and filtration through the shell-filter lagoon. Following DER's statement of intent to issue a permit for construction of the wastewater treatment facility as described in the April 10, 1984, application by Smith, DER became concerned about the potential toxicity of calico scallop wastewater, based upon its own studies. As a consequence, Smith amended the application for wastewater treatment facility to include use of chemical coagulation and flotation. This amendment occurred in March 1985, and the wastewater treatment process in that application envisioned the use of an electroflotation wastewater system. In view of toxicity problems experienced with the testing related to the use of an electroflotation wastewater treatment system, this treatment alternative was discarded in favor of a dissolved air flotation (DAF) system. This system was pursuant to an amendment to the application effective May 31, 1985. This amendment of May 1985 was in furtherance of the order of the hearing officer setting a deadline for amendments to the application. DER issued an amended intent to grant permits for the DAF unit and the associated pipeline and that action dates from June 28, 1985. The Petitioners oppose the grant of these permits for the DAF unit and pipeline, and under the auspices of their initial petition have made a timely challenge to the grant of a permit for the installation of the DAF wastewater treatment unit and associated pipeline. It is the DAF unit and pipeline that will be considered in substance in the course of this recommended order. On July 6, 1984, Smith sought an easement from the State of Florida, Department of Natural Resources (DNR) for the installation of the pipeline. This was necessary in view of the fact that the pipeline would traverse sovereignty lands which were located beneath Trout Creek, Palmo Cove and the St. Johns River. On December 17, 1984, DNR issued a notice of intent to submit that application to the Board of Trustees of the Internal Improvement Trust Fund with a recommendation of approval. This action was challenged by the Petitioners on January 7, 1985, in a petition for formal hearing challenging the grant of the easement. DOAH Case No. 85-0277 concerns this challenge to grant of an easement. Originally, by action of January 28, 1985, the easement case was consolidated with the present DER permit actions. At the instigation of DNR, the easement case was severed from consideration with the present action. The order of severance was entered on July 31, 1985. The DNR case will be heard on a future date yet to be established. The DNR case was severed because that agency preferred to see test results of treatment efficiencies following the construction of the DAF unit. By contrast, the present DER cases contemplate a decision being reached on the acceptability of the construction of the DAF unit and attendant features, together with the pipeline on the basis of theoretical viability of this entire system. This arrangement would be in phases in which the construction of the upland treatment system would occur within 90 days of the receipt of any construction permit from DER, followed by a second phase within which Smith would construct the pipeline within 60 days of receipt of any other necessary governmental approval, such as the DNR easement approval. Furthermore, DER would wish to see the results of an integrated treatment system involving the upland treatment by the DAF unit and its attendant features and the use of the pipeline and the availability of a mixing zone, that is to say the end of pipe discharge, before deciding on the ultimate question of the grant of an operating permit for the wastewater treatment system. The quandary presented by these arrangements concerns the fact that discharge from the DAF treatment unit would be temporarily introduced into Trout Creek, pending the decision by DNR to grant an easement for the pipeline and the necessary time to install that pipeline. Given the difficult circumstances of these actions, there is raised the question of the propriety of discharging wastewater into Trout Creek pending resolution of the question of whether DNR wishes to grant an easement to place the pipeline over sovereignty submerged lands. This is a perplexing question in view of the fact that DNR requested severance from the present action, thereby promoting further delay in the time between any installation of the upland treatment system and the pipeline. Finally, Trout Creek is an ecosystem which has undergone considerable stress in the past, and it is more susceptible to the influences of pollution than the St. Johns River would be as a point of ultimate discharge from the pipeline. This dilemma is addressed in greater detail in subsequent sections within the recommended order. Petitioner River Systems Preservation, Inc., is a nonprofit organization comprised of approximately seven hundred persons. The focus of the organization is to protect and enhance the environment of northeast Florida. The individual Petitioners, Pinkham E. Pacetti, Robert D. Maley, Ruth M. Whitman and others, are members of the corporation who own property or live near the scallop processing plant of Respondent Smith. In addition, Pacetti owns a marina and recreational fishing camp that is located across Trout Creek from Smith's plant. Pacetti's fish camp dates from 1929. On the occasion of the opportunity for the public to offer their comments about this project, a significant number of persons made presentations at the public hearing on August 29, 1985. Some members of the public favored the project and others were opposed to the grant of any permits. St. Johns County Board of County Commissioners, in the person of Commissioner Sarah Bailey, indicated opposition to the project, together with Bill Basford, President of the Jacksonville City Council. Warren Moody, the vice-chairman of the Jacksonville Waterways Authority spoke in opposition to the project. The Florida Wildlife Federation and the Jacksonville Audubon Society expressed opposition to the project. The officials related the fact of the expenditure of considerable amounts of public tax dollars to improve water quality in the St. Johns River and their concern that those expenditures not be squandered with the advent of some damage to the St. Johns River by allowing the permits in question to be issued. These officials considered the St. Johns River to be a significant resource which they are committed to protecting. The City of Jacksonville, Clay County, Green Cove Springs, the Jacksonville Waterways Authority, the Northeast Florida Regional Planning Council and St. Johns County expressed opposition to the project contemplated by the present permit application, through the adoption of certain resolutions. These broad-based statements of opposition were not spoken to in the course of the hearing by members of any technical staffs to these governmental institutions. Private members of the public, some of whom are affiliated with River Systems Preservation, Inc., expressed concern about water quality violations, harm to fish and other environmental degradations that have been caused by the Homer Smith operation in the past and their belief that these problems will persist if the permits at issue are granted. Those persons who favored the project, in terms of public discussion, primarily centered on the idea that, in the estimation of those witnesses, fairness demanded that Smith be afforded an opportunity to demonstrate that this proposed system of treatment was sound and the quality of the water being discharged from the Homer Smith plant was not as bothersome as had been portrayed by the persons who opposed the grant of environmental permits. Industrial Wastewater Construction Permit Treatment System Description of Homer Smith's Plant and Its Operation. The source of water used for the processing of the scallops at the Homer Smith plant is a well which is located on that property. Homer Smith is allowed to withdraw 300,000 gallons of water per day in accordance with a consumptive use permit that has been issued by the St. Johns River Water Management District. To ensure Smith's compliance with this permit, a metering device is located on the well. Typically, the plant operates an eighteen-hour day, five days a week, using water at a rate of 200 gallons per minute. This would equate to 215,000 gallons per day over an eighteen-hour day. Prior to the imposition of restrictions by the Department of Environmental Regulation through the consent order, this facility had processed as much as 40,000 pounds of scallops each day, for a total of 36,000 gallons each week, at a gross revenue figure of $225,000 per week. Characteristics and Frequency of Effluent Discharge The wastewater generated by the scallop processing that is done at the Homer Smith plant is principally constituted of the well water used to clean the scallops, proteinaceous organic materials, and metals. The metals are introduced into the wastewater stream from the scallop tissue. The wastewater stream also has a certain amount of sand and grit, together with shell fragments. The concentrations of organic materials within the wastewater stream are at high levels. There is also an amount of fecal coliform bacteria and suspended solids. The pollution sources within the wastewater stream include total suspended solids (TSS), biochemical oxygen demand (BOD), nutrients (nitrogen and phosphorus) and the coliform bacteria. In the neighborhood of 30 percent of the BOD in the wastewater is soluble. The balance of the BOD is associated with the suspended solids. With time the organic materials in the wastewater stream will decompose and with the decomposition present certain organic decomposition products, which would include ammonia, amines and sulfides. Heavy metals in the wastewater have been in the scallop tissue and are released with the cleaning of the scallops. These metals include cadmium, copper, zinc, iron, manganese, silver and arsenic. The presence of these metals within the tissues of the scallops are there in view of the fact that the scallops are "filter-feeders" which have taken in these elements or metals that naturally occur in the ocean water. The permit application contemplates an average of five days a week of operation for eighteen hours a day. Notwithstanding the fact that in the past the Homer Smith Seafood operation had processed scallops seven day week, twenty- four hours per day, Smith does not desire to operate more than five and a half days a week in the future. That is perceived to mean five eighteen-hour days and a twelve-hour day on the sixth day. The treatment system contemplated here is for a flow volume of around 200 gallons per minute during normal operation. The system can operate as high as 300 gallons per minute. That latter figure approaches the design capabilities of the treatment system proposed. Wastewater is discharged only when scallops are being processed. There is basically 1:1 ratio between the volume of well water used to process the scallops and the amount of wastewater discharged. Proposed Treatment System and Alternatives As already stated, there is no specific industry standard set forth in the DER rules which would describe technology-based standards for the treatment of calico scallop wastewater. In those instances where the agency is confronted with an industry for which technology-based standards have not been established, DER examines the question of whether that effluent is amenable to biological treatment as contemplated in Rule 17-6.300(1)(n)1., Florida Administrative Code, as an alternative. Biological treatment is a treatment form normally associated with domestic waste and the imposition of this treatment technique is in furtherance of achieving a secondary treatment standard found in Chapter 17-6, Florida Administrative Code, which results in 20 mg/L of BOD and TSS, or 90 percent removal of those constituents, whichever is the greater performance in removal efficiency. In the absence of specific standards related to the calico scallop industry, and in the face of the interpretation of its rules in which DER calls for an examination of the possibility of biological treatment as an alternative to treatment specifically described for a given industry, it was incumbent upon this Applicant to examine the viability of biological treatment of the scallop wastewater product. The Applicant has considered biological treatment as an alternative and rejected that treatment form, in that Smith's consultants believe the wastewater is not amenable to biological treatment. By contrast, Petitioners' consultants believe that biological treatment should be the principal focus in treating the scallop wastewater and contend that biological treatment is a more viable choice when contrasted with the option chosen by the Applicant. If this waste is not amenable to biological treatment, Rule 17-6.300(1)(n)1., Florida Administrative Code, envisions an acceptable or minimum level of secondary treatment shall be determined on a case-by-case basis. In the instance where biological treatment is not a reasonable choice, the Applicant is expected to achieve treatment results which are comparable to those arrived at in treating domestic waste by the use of biological treatment techniques. On this occasion, DER had not established what they believe to be a comparable degree of treatment for calico scallop waste, assuming the unavailability of biological treatment. The present case is a matter of first impression. As a result, the idea of a comparable degree of treatment shall be defined in this hearing process, assuming the inefficacy of biological treatment. In that event, DER must be assured that the proposed treatment plan has an efficiency that rivals the success which biological treatment promotes with domestic waste, taking into account the quality of the effluent prior to treatment, available technology, other permitting criteria and the ambient conditions where the waste stream is being discharged. In arguing in favor of biological treatment, Petitioners pose the possibility of an integrated system in which primary settling tanks or clarifiers would be used together with a biological treatment step, which is referred to as a trickling filter, followed by final settling by the use of tanks or clarifiers in an effort to achieve BOD concentrations in the range of 200 mg/L to 400 mg/L. In this connection, the dissolved air flotation system is seen in the role of alternative to the initial stage of settling of the constituents within the wastewater stream. It is not regarded as the principal means of treatment of the waste. The trickling filter system as a biological treatment medium involves the use of a bacterial culture for the purpose of consuming the oxygen-demanding constituents, BOD. The trickling filter technique, if a viable choice, has the ability to remove 70 to 75 percent of BOD and TSS. Petitioners suggest further treatment of the waste beyond primary and final settling and trickling filter can be afforded by involving activated sludge, which according to their experts would end up with a biological oxygen demand in the 20 mg/L range. Although the constituents of the Smith plant's waste are of a highly organic nature, and, at first blush a candidate for biological treatment by use of the trickling filter, the problem with this form of treatment has to do with the intermittent flow in the Smith operation. This intermittent flow is caused by the fact that the plant does not operate throughout the year. The plant operations are seasonal, depending on calico scallop harvesting which does not occur on a routine basis. Therefore, the problem is presented of trying to keep the biological treatment system "alive" and operating at levels of efficiency which can be expected to maintain the percentage of removal of BOD and TSS that a healthy system can deliver. The bacteria colonies which are vital to the success of the biological treatment system must be fed on a continuous basis to maintain balance in the population of the colony. This would be a difficult undertaking with the Smith operation, given the interruptions in operations which could lead to the decline in the bacterial population and a poorer quality of treatment once the operations were resumed. This finding takes into account the fact that the colony can survive for a week or two by simply recirculating water over the filter. Obviously, in order to maintain necessary efficiencies within this biological treatment, the bacteria must do more than survive. The further suggestion that has been offered that the bacteria could be sustained for longer periods of time by feeding them seafood waste or dog food are not found to achieve the level of efficiency in the operation that would be necessary in posing biological treatment as an alternative. Again, it is more of an intervening measure designed to assure the survival of bacteria pending the continuation of the operations of the plant, as contrasted with a system which is continual and taking into account the uniformity of the waste product more efficient. Another problem with feeding the bacteria when the plant is not operating is that of disposing of the waste produced when this auxiliary feeding is occurring. Just as importantly, biological treatment is questionable given the long retention times necessary for that process and the build-up of toxic levels or concentrations of ammonia. The Applicant had employed an aerated lagoon in attempting to treat the waste and experienced problems with ammonia build up. Although this system did not call for the degree of treatment of the waste prior to the introduction into the lagoon that is contemplated by the present proposal of the Applicant, it does point to the fact of the problems with ammonia in the biological treatment system. Dr. Grantham, a witness whose testimony was presented by the Petitioner, conceded the difficulty of removing ammonia from the trickling filter. Moreover, the biological treatment system is not especially efficient in removing metals and phosphorus from the wastewater. Alternative treatment would be necessary to gain better efficiency in removals of those constituents. The trickling filter is expected to gain 50 percent metals removal, which is inadequate given the concentrations of heavy metals found in the scallop wastewater. Phosphorus could be removed after treatment by the trickling filter by the use of lime or alum. Assuming optimum conditions in the use of biological treatment after primary and final settling, thereby arriving at a BOD level of 200 mg/L, it would then be necessary to make further treatment by the use of activated sludge to see 20 mg/L BOD. The problem with activated sludge is related to the fact that this form of treatment is particularly sensitive to interruptions in flow, which are to be expected in this wastewater treatment setting. On balance, biological treatment does not present a viable choice in treating scallop waste. That leaves for consideration the question of whether the Applicant's proposal would afford a comparable degree of treatment to that expected in the use of biological treatment of domestic waste. The manufacturer of the dissolved air flotation unit or DAF system proposed, known as the Krofta "Supracell," offers another piece of equipment known as the "Sandcell" which in addition to the provision for dissolved air flotation provides sand filtration. The Sandcell might arrive at BOD levels of 400 mg/L. However, the testimony of the witness Lawrence K. Wang, who is intimately familiar with the Krofta products, in responding to questions about the use of the Sandcell system and suggestion that the system would arrive at 400 mg/L BOD responded "could be." This answer does not verify improvement through the contribution of sand filtration. For that reason inclusion of a Sandcell for filtration of BOD is not suggested in this fact finding and the system as proposed must be sufficient in its own right. Having realized the need to provide greater treatment than screening or filtering the waste stream, the Applicant attempted to design a treatment system using flotation technology together with chemical precipitation and coagulation. At first the Applicant examined the possibility of the use of electroflotation (EF). This involved the collection of wastewater in a retention tank and the generation of an electric current to create a series of bubbles to float insoluble flocs. Those flocs are caused by the use of ferric chloride, sodium hydroxide and various polymers which are added to the waste stream. The flocs are then pushed to the top of the chamber by the air bubbles, and this particulate matter is skimmed off by the use of a paddle. Pilot testing was done of the electroflotation technology and showed promising results, so promising that a full-scale electroflotation unit was installed and tested. The full-scale electroflotation showed reasonable removal of BOD, TSS, nutrients, coliform and trace metals. This technique was discarded, however, when bioassay testing of the treated effluent was not successful. In examining the explanation for the failure, the experts of the Applicant were of the opinion that certain chemical reactions were occurring as a result of the passage of the electrical current through the wastewater stream. When this problem with acute toxicity could not be overcome through a series of adjustments to the process, the Applicant decided to test another form of flotation, which is referred to as dissolved air flotation (DAF). This system employs the use of chemicals to create insoluble flocs. Unlike the electroflotation unit, though, it does not utilize electrical currents to create the air bubbles employed in the flotation. The dissolved air flotation thereby avoids problems of toxicity which might be attributed to the passage of electrical current through the water column. The present system as proposed by the Applicant has a number of components. The first component of treatment involves the passage of raw wastewater through a mechanical screening device, which is designed to remove a certain number of particulates by catching those materials on the screen. That material is then removed from the plant and disposed of off site. The balance of the wastewater after this first stage of treatment passes into a sump area and from there into a primary mix/ aeration tank. This water is then chemically treated to facilitate the formation of insoluble flocs. The chemically treated wastewater then enters a premanufactured Krofta Supracell 15 DAF unit which is designed to form bubbles by the use of pressurized air, with those bubbles floating the waste materials within the floc to the surface. Again, this method does not use electrolysis. The floated solid materials are then skimmed from the surface and directed to a holding tank and subsequently pumped to sludge drying beds. Some of the treated wastewater is recycled through the DAF unit after pressurization and in furtherance of forming the necessary bubbles for the DAF unit. The balance of the water is directed to a force main lift station. This water would then be transported through the eight-inch PVC pipe some 13,000 feet into the main channel of the St. Johns River where it is distributed through a five port diffuser. The screening mechanism spoken of had been installed in mid-December 1984 and has been used since that time to filter the wastewater. The screening mechanism is in substitution of settling tanks and shell pits. The shell pits which had been used before presented problems with odors as well as the ammonia build up which has been addressed in a prior paragraph. The removal efficiency of the screening mechanism is 30 percent of particulates associated with pollution parameters, as example BOD, total Kjeldahl nitrogen, total phosphorus and TSS. The frequency of the transport of these screened materials to the off site disposal is four to six times a day and the screen is decontaminated at the end of each day when the operations are closed. The application contemplates the same operating procedures of disposal and maintenance with the advent of any construction permit. The primary mix/aeration tank aerates the wastewater and through that process and the retention time contemplated, equalizes the flow regime and promotes a more balanced concentration of waste materials prior to the introduction of that wastewater for chemical coagulation and flotation. This step in the treatment process enhances the treatment efficiency. Some question was raised by the Petitioners on the size of the primary mix-aeration tank as to whether that tank was sufficient to equalize the flow, and conversely, the impacts of having too much retention time built into that tank, which would promote the build-up of toxic concentrations of ammonia in the wastewater. The retention time within the sump and the primary mix-aeration tank approximates one and one-half hours. The retention time and size of the primary mix-aeration tank are found to be acceptable. This design appropriately addresses concerns about the build-up of decomposition products and toxicity, to include ammonia. The sludge which collects in the primary mix-aeration tank will be pumped back to the sump pit by return flow. The sump pit itself will be pumped out in the fashion of cleaning a septic tank on the basis of once a week. The sump pit also receives the return flow of leachate from the sludge drying bed. Once equalization of flow is achieved in the primary mix-aeration tank, that wastewater is then treated by the use of alum, sodium aluminate and polymers. The purpose of this treatment is to convert soluble and insoluble organic matter such as TSS and BOD, trace elements and phosphorus into insoluble flocs that can be removed by flotation. These combinations of chemicals and dosage rates have been tested in electroflotation and dissolved air flotation bench and pilot scales for use associated with this project and a list of appropriate chemicals and ranges of dosage rates has been determined. It will be necessary for these chemicals and general dosages to be adjusted in the full- scale operation under terms of the construction permit. This facet of the treatment process must be closely monitored. Once the wastewater stream has received the chemical treatment, it is introduced into the Krofta Supracell 15 DAF unit. This unit is 15 feet in diameter, and within this cylinder bubbles are generated by pressurizing some of the chemically treated wastewater and potentially clean tap water. The use of clean tap water promotes dilution of the wastewater stream as well as greater efficiency in the production of the bubbles. Chemically treated wastewater is brought into the cylinder through the back of a revolving arm that moves around a center column of the DAF unit at the speed of the effluent flow. The purpose of this mechanical arrangement is to eliminate horizontal water velocity, to protect the integrity of the flocs that are being formed by the use of the chemicals. Those flocs float to the surface in a few minutes' time, given the normal turbulence and shallow depth of the DAF unit. This limited retention time also avoids ammonia build up. The floating material is then scooped and poured into a stationary center section and is discharged by gravity to the sludge holding tank. Wiper blades which are attached to the revolving arm scrape the bottom and sides of the tank and discharge any settled sludge to a built-in sump in the DAF unit. These materials which are settled in the bottom of the DAF cylinder are transported through the sludge holding tank and eventually placed in the sludge drying beds. The treated wastewater is removed by an extraction pipe associated with the center section of the DAF unit. It is then discharged. The use of clean tap water from the well and the ability to recycle the waste stream can promote greater treatment efficiency in terms of removal of undesirable constituents of the waste stream and the reduction of concentrations of those materials. As a measurement, approximately 8 percent of the wastewater flow will be removed as sludge. This sludge is sufficiently aerated to be reduced in volume by about one-half over a period of ten to thirty minutes in the sludge holding tank. It is then sent to the sludge drying beds. The sludge drying beds are designed to accommodate 30,000 gallons of sludge. They are 60 feet long, 25 feet wide and 4 feet deep. Those drying beds are of greater size than is necessary to accommodate the volume of sludge. The sludge drying beds have a sand and gravel bottom. The water drains from the sludge as leachate and returns to the sump pit in the treatment system at a rate of five to ten gallons a minute. Some concern has been expressed that the "gelatinous" nature of the sludge will make it very difficult to dewater or dry. This opinion is held by experts of the Petitioners, notwithstanding the fact that polymers are used in the treatment process. One expert in particular did not believe that the sludge would adequately dry. Having Considered the evidence, the opinion that the sludge will not dry sufficiently is rejected. Nonetheless, it is incumbent upon the Applicant to monitor drying conditions of the sludge very carefully and, if need be, to add some chemical such as calcium hydroxide to enhance the drying capacity of the sludge material. It is anticipated that the sludge will be removed once a day and this arrangement should be adhered to. With adequate drying, the sludge material can be removed with the use of shovels, rakes and a front-end loader as proposed by the Applicant. With frequent removal and adequate drying, problems with odors can be overcome, and problems with ammonia build up and the generation of unreasonable levels of bacteria can be avoided. Should problems with odors, ammonia and bacteria occur, it would be necessary for the Applicant to purge the drying beds, to include the sand and gravel which had been invested with the sludge materials that had caused the problems. Although Smith has not tested the drying bed leachate as to specific nature, the treatment process can be expected to deal with problems of any build-up of ammonia concentrations, fecal coliform bacteria and other organic decomposition products. This pertains to the ability to remove these offending substances from the site in terms of removal of the residual solids and the ability to treat those parameters within the leachate as the wastewater is cycled through the system. The treated wastewater will be transported to a pumping station by gravity flow and then pumped via the pipeline to the proposed point of discharge in the main channel of the St. Johns River. This pipeline is constituted of fabricated sections of pipe 20 feet in length, connected with bell and spigot joints, rubber gaskets and solvent welding. The treated wastewater is released into the river through a five point diffuser which has three-quarter inch openings angled at ten degrees from the horizontal bottom. The pipeline is anchored with prefilled 80-pound concrete bags attached with polypropelene straps which are placed at 8-foot intervals. These are placed to keep the pipe from floating. The diffuser is supported by four piles driven into the river bottom and surrounded by a series of concrete bags. The purpose of this arrangement is to hold the diffuser in place and to protect it against potential damage from anchors or other possible impact. The Applicant acquiesces in the choice to have the pipeline tested for leaks once a month in the period June through September and every other month during other parts of the year. If leaks are found, the Applicant would be responsible for repairing those leaks. As stated before, it is necessary for the Applicant to receive permission from the State of Florida to be granted an easement before the pipe can be installed. Prior to that permission being granted, the treated wastewater would be placed in Trout Creek, which is adjacent to the processing plant. Predicted End of Pipeline Quality of the Effluent In trying to predict the quality of effluent at the end of the pipeline, bench scale and pilot scale testing was done related to the DAF technology. This testing was done related to screened wastewater that was collected from the plant in April 1985. In this connection two series of DAF bench scale tests were performed. They related to samples collected on April 18 and 19, 1985, which were packed in ice and shipped directly to a research laboratory in Lenox, Massachusetts, where they were treated with chemicals and a laboratory size DAF unit. The concentration of the wastewater parameters were measured and recorded before and after treatment, and the results of those tests are set forth in the Applicant's Exhibit A-4(B)(3), at Table 2-1. The pilot scale testing that was done in this case related to a 4-foot diameter DAF unit which had been installed at the Homer Smith plant. This testing occurred in April 1985. The basis of the testing was samples taken on April 15 and 19, 1985. Again, wastewater parameters were measured before and after treatment and the results are set forth in Applicant's Exhibit A-4(B)(3), at Table 2-1. When the initial testing was done with the DAF, results for total coliform bacteria uniformly fell below a range of 35 organisms/100 ml. Subsequent pilot tests yielded higher bacterial counts which would indicate that there was a build-up of bacteria within the DAF unit. This verifies the need to require that the DAF unit contemplated by the application be routinely cleaned or sanitized to avoid the build-up problem. TSS in the pilot unit effluent was reduced to 40 mg/L and lower. The capacity for metals removal in the pilot scale testing was good pertaining to copper and zinc. The ability to remove cadmium showed a result of 0.013 and 0.015 mg/L. The best performance in the pilot scale testing related to BOD removal showed a value of 510 mg/L. It should be noted that the bench scale testing and pilot scale testing were in the face of significant variations in the amount of BOD presented by the screened wastewater. This identifies the need to pay close attention to the removal efficiency of the system related to the BOD parameter in order to achieve consistent levels of BOD following treatment. The system under review is referred to as full-scale treatment. This treatment can be expected to exceed the levels achieved in the DAF bench and pilot scale testing because: (a) As a general proposition, treatment efficiency improves as the scale of machinery increases from bench to pilot to full-scale; (b) The bench and pilot scale tests were run without the benefit of the primary mix-aeration tank and the benefits derived from that part of the treatment apparatus, that is to say, uniformity of the flow and better dispersion of the constituents of the wastewater stream, prior to chemical treatment; (c) The pilot DAF unit used exclusively recycled wastewater to undergo pressurization for the creation of the air bubbles. In the course of the hearing it was established that approximately 50 gallons per minute of clean tap water could be brought in to the treatment process resulting in the formation of more bubbles and the facilitation of up to 10 percent greater treatment efficiency based upon that change. The other contribution made by the use of clean tap water was the possibility of as much as a 20 percent dilution of the wastewater stream, in terms of concentration of constituents within the wastewater stream; (d) In a full-scale operation, the opportunity is presented to routinely adjust the chemical dosages as well as select among a range of chemicals in order to achieve the greatest treatment efficiency; (e) In employing routine sanitization of the DAF unit by use of a mild chlorine compound, the tendency to accumulate coliform bacteria can be overcome. Removal of this adverse influence improves the water quality. In traveling through the pipeline, the transit time is in the range of two to three hours. At a normal rate of 250 gallons per minute of discharge, the transit time in the pipeline is 2.25 hours. Given the constituents of the wastewater, bacterial populations can be expected and could conceivably consume sufficient amounts of oxygen to affect the dissolved oxygen levels within the wastewater as it exits the pipe at the diffuser ports. In addition, there is some possibility of ammonia build up within the pipeline. To avoid the build up of bacteria at harmful levels, sanitation of the DAF unit must be accomplished. In addition, the pipeline itself should be flushed with clean water at the close of operations each day and treated with small amounts of chlorine to address bacteria which may form within the pipeline. This avoids the increasing concentrations of ammonia and protects against lowered dissolved oxygen concentrations and the possibility of increased levels of toxic substances in the effluent which might be attributable to the proliferation of bacteria and the build-up of ammonia during the transport through the pipeline. Taking into the account the nature of this wastewater and the velocity associated with the transport and the sanitization of the pipeline, sedimentation associated with organic solids or other materials will not present a problem. The pollution parameters associated with the treated effluent at the point of discharge from the pipeline can be expected to meet Class III orders, excepting unionized ammonia, specific conductance, copper, cadmium, pH and zinc. In order to achieve satisfactory compliance with regulatory requirements related to those parameters, the Applicant has requested a two-meter mixing zone. The purpose of that mixing zone would be to afford an opportunity for dispersion and mixing in the ambient water before imposition of water quality standards. The implications of that mixing zone are discussed in a subsequent section to the fact finding within the Recommended Order. In effect use of the mixing zone will promote compliance with standards pertaining to the subject parameters. Petitioners point out the fact that the Applicant has based its assumptions on the results of treatment on the availability of four sets of data which were obtained from DAF effluent--two sets of data coming from the bench tests and two sets of data from the pilot plant. Further, there is an indication of the variation in quality of the effluent from one test to the next and the need to employ different dosage rates of chemicals in the face of those variations. The full-scale system utilizes a number of techniques to gain some uniformity in the quality of the effluent prior to chemical treatment and thereby some uniformity in the amount of chemicals necessary to treat the effluent. This overall system can then be expected to produce treated wastewater that is basically uniform in its constituents. Petitioners point out the limited amount of data in the testing related to BOD. There were, in fact, only two data points: one related to the bench system and one related to the pilot system pertaining to BOD, both of these the product of different chemical dosages for treatment. Again, the system that is at issue in this proceeding can be expected to arrive at a more consistent level of BOD than is depicted in the results pertaining to bench scale and pilot scale testing. In fact, those results were not remarkably disparate in that the bench sale test produced 560 mg/L and the pilot scale test produced 510 mg/L. While the data related to BOD is limited, it still gives sufficient insight as to the probability of successful full-scale treatment and the test data is found to be a reliable indication of success in achieving the goal of 510 mg/L BOD. Contrary to the Petitioners' perceptions, the treatment efficiency is improved with the system that is under review. Petitioners believe that the bench and pilot scale testing not only is unrepresentative of the full-size DAF system, they also believe that the full-size system represents a lesser quality of treatment. In this regard reference is made to features which would adversely affect the treatment efficiencies. The first of those pertains to leachate which drains from beneath the sludge drying beds and is recirculated to the existing sump pit and added to the waste stream. Sludge which sits in the drying bed does decompose and causes biochemical reactions to occur, as Petitioners suggest. Moreover, no specific testing has been done of the leachate to ascertain the ammonia concentrations, pH or other chemical characteristics. Nonetheless, given the intention to clean out the residual matter within the sump pit frequently, and the flexibility to make that cleanup more routinely, and the fact that this amount of leachate is comparatively small in its ratio to wastewater which is being sent through the system for treatment, the leachate is not found to be an unmanageable problem. Nor is the sludge a problem. Likewise, the amounts of heavy metals within the leachate can be accommodated. Concerns expressed by the Petitioners related to the organic materials in the primary mix-aeration tank that is being returned to the sump pit can also be dealt with by the evacuation of the materials in the bottom of the sump pit. This can be achieved more frequently than on a weekly basis if that becomes necessary, and in doing so avoid problems with concentrations of ammonia, bacteria, amines, sulfides and general organic decomposition products. These materials which are returned to the treatment process as wastewater reintroduced into the primary mix-aeration tank can be adequately addressed in the subsequent treatment that occurs by reaeration, the use of the chemicals and DAF flotation. The retention inherent in the sump pit, primary mix-aeration tank and sludge drying bed has a potential to cause problems with ammonia build-up; however, the problems can be satisfactorily addressed, as well as potential problems with other toxic substances in the effluent, by routinely taking the residual material in the sump pit and sludge drying bed out of the treatment system. While the specific chemicals and precise dosage rates to be used with a full-size DAF system remain open, the basic concept of chemical treatment has been identified sufficiently. The precaution that is necessary is to make certain that close monitoring is made of the results of changes in the chemicals and dosage rates. Likewise, special attention should be paid to the implications of adjustments in the pH of the effluent to make certain that compliance is achieved with the Class III water criterion related to changes in pH above background. Adjustments can be made without violating Class III water standards related to pH. In testing that was done pertaining to the electroflotation effluent, a number of other chemicals were observed, to include trimethylamine, dimethyl sulfide, chloroform and other hydrocarbons. There is some indication of the presence of dichleoroethane, ethylbenezene and other aromatics. The possibility exists that these substances may also be products within the DAF effluent. In that event, the critical question would be whether they have any adverse effect in the sense of influences on the ability of the effluent to pass bioassays and the ability of the effluent to comply with standards related to other parameters such as dissolved oxygen, BOD, and TSS. The routine testing which is called for by the draft permit, which is deemed to be appropriate, would create a satisfactory impression of the materials set forth in the paragraph in the sense of the implications of their presence and allow any necessary adjustments in treatment. While the effluent produced in the testing on the part of the Applicant is different, it is representative, and the treated effluent which will be produced in the full-scale system will be of a better quality and present less adverse impacts than shown in the past testing. Petitioners question whether the Applicant has given a conservative portrayal in analyzing the effluent. In particular, it is urged that the Applicant claimed to be vying for use of the bench scale testing as a conservative depiction of the results of treatment. In this connection, the impression given in the hearing was that of ascendancy in treatment efficiency beyond the use of bench scale, pilot scale and ending in full-scale treatment. As pointed out by Petitioners, in making his case the Applicant has used results of bench and pilot scale testing. As example, use was made of the results of testing in the pilot scale in describing the removal effioiencies related to cadmium, whereas in the measurements of nitrogen concentrations the bench scale result was better than that of the pilot testing and was utilized. The real question is whether the overall testing has given some reasonable indication of success in full-scale treatment. To that end, use of results from either the bench scale or pilot scale testing is appropriate, and those results point to success in the full-scale operation. The system that is proposed is designed to address fluctuations in flow and concentrations in the effluent, given the primary mix-aeration tank contribution and the ability to recycle flow within the DAF unit, with the use of clean tap water. This will allow the Applicant to deal with the remarkable differences in BOD that were seen in the test period, ranging from 900 to 3000 mg/L. COD data as well as BOD data is limited but is found to be an ample depiction of potential treatment efficiencies related to that former parameter. In addition to the aforementioned references to changes in chemicals in the treatment process, Petitioners characterize the use of clean tap water in the recycle flow as being "unsubstantiated speculation." While the use of tap water was discussed in a theoretical vein, that discussion is found to be an accurate assessment of the value of the contribution of clean tap water to the treatment system. Impacts on St. Johns River Ambient Water Quality and Conditions The St. Johns River and the area of the proposed discharge is a riverine estuary. It has a freshwater source flowing from the south and a tidal ocean boundary to the north. The confluence of freshwater flow and tidal influences causes the water movement within this area to be oscillatory. That is to say that at different times the water will flow downstream, to the north, and upstream, to the south. There are occasions in which the net flow over a given tidal cycle will be zero; however, the water is always moving. Conductivity and chloride data indicate that the freshwater flow is the dominant flow compared to tidal influences. The extrapolation of available flow data indicates that there is a net downstream flow of fresh water averaging approximately 6,000 CFS. The St. Johns River at the point of discharge is over one and a half miles wide and relatively shallow with maximum depth in the range of 3 to 3.5 meters. Given the fact of the width and depth in this segment of the river, and the imposition of wind conditions and tidal influence, the water is well mixed and flushed. There is no stratification in this portion of the river. The Applicant looked into the question of current bearing and velocity in depths between two to fourteen feet in the water column. Eleven sampling stations were utilized in arriving at information about current bearing. This observation was over an eleven-nautical-mile stretch of the main channel of the St. Johns River. These stations are depicted on Applicant's Exhibit 38. In this portion of the river the current at all measured depth was flowing up and down the main channel. Within these sections there is no indication of a pronounced subsurface water movement toward the east and west banks of the river. Current velocities within the three stations closest to the POD averaged in the range of 0.5 feet per second and velocities in the other stations found within the main channel were within that range of movement. By contrast current velocities within the embayment areas along the east bank of the river were substantially weaker. DER conducted two studies using tracing dyes poured into the St. Johns River at the approximate point of discharge and monitored the course of dispersement of that dye. During this observation the dye was constantly replenished while being carried on the currents. While the dye remained within the area of the main channel, it stayed on the east side of the river as it moved down river on the outgoing tide in the direction of Smith's Point and the Shands Bridge. As the tide was slowing before the change of tide, the dye drifted for approximately two hours in the immediate vicinity of the point of discharge. The DER dye study was a fairly gross measurement of the direction of water movement within the river beyond the point of discharge. It tended to confirm that the water flow was basically up and down river, depending on whether the tide is incoming or outgoing. The studies were not sufficiently refined to speak with any certainty on the possibility that some part of the flow regime would move toward the east or west bank of the river. Nonetheless, in examining the nature of the shallow embayment areas along the banks of the St. Johns River, they are not seen to be subject to the basic flow regime that is occurring in the main channel during tide events. The bathymetry in this area is such that if the main flow regime was having some influence on the embayment areas, the depths within those embayments would be more similar to the depths found in the main channel of the river. Petitioners have employed a number of dye and drogue measurements to try to give a more accurate depiction of the influence of flow within the main channel upon the dispersion of effluent upon discharge and the possibility of those pollutants reaching the embayment areas. While there is no dispute over the fact that Trout Creek is a tributary to the St. Johns River with some tidal influences being shown in that Creek and there is no dispute that water from the St. Johns River flows in and out of Palmo Cove and Trout Creek, there does not appear to be a significant flow of water from the St. John River into the cove and creek from the main channel, in particular from the area of the point of discharge. One of the witnesses of the Petitioners, Sandy Young, did a dye procedure in which a plume was allowed to develop over a distance of approximately 1,000 feet. Although some slight lateral variation was shown in the dye plume, it did not identify a basic flow pattern toward the embayment areas on the east side of the river. The DER dye study was over a distance of some eight thousand feet and also showed some minor lateral variation. Both of these dye studies tend to show a basic flow pattern within the main channel. The dye study run by the Petitioners' witness White gave the same basic depiction as seen in the studies by DER and Young and did not identify a flow pattern out of the main channel toward the embayment areas. In the drogue studies run by Young three Chlorox bottles were filled to 95 percent of volume with water and released at the point of discharge. They were followed for a period of five hours. They moved initially with the outgoing tide toward Jack Wright Island and then when the tide slowed, the drogues slowed. When the tide changed with the incoming tide, the drogues moved toward the center of Palmo Cove. The drogue studies by Young do tend to indicate that some water was exchanged from the main channel at the point of discharge and the embayment areas. It is not a very exact measurement as it only deals with the surface area of the water column, given the wind and wave conditions existing on that occasion. It is in no way representative of the flow direction of the rest of the water column. Therefore, although it may tend to identify that some of the pollutants leaving the point of discharge may find their way to Palmo Cove, it does not establish that quantity of that pollution dispersion and the significance of that dispersion. Based upon this evidence it cannot be seen to be so revealing that the assumptions made by the applicant in trying to identify the dispersion characteristics of the effluent at point of discharge are negated based upon the results of the drogue study. The drogue study which Young did and the observation of the movement from Smith's Point to Little Florence Cove are no more compelling than the dye studies done at the point of discharge. When the Petitioners suggest that there is some influence by centrifugal force pushing the water to the outside of the curve toward the eastern bank, they are correct. However, the contention by the Petitioners that the incoming and outgoing tides sweep to the eastern shoreline of the St. Johns River moving toward Pacetti Point, Palmo Cove, Florence Cove and Smith Point is not accepted. Again, the general flow regime is up and down the main channel of the river and not primarily to the eastern bank. Finally, the fact that the Tetratech data produced for the benefit of the Applicant showing the flow pattern within the overall water column, which indicated that the general direction is the same at the top or bottom of the water column, did not tend to identify the fact that pollutants throughout the water column will be dispersed into the embayment areas from the point of discharge. The data collected in the main channel seem to establish that the water was flowing up and down the channel at depths below the surface. The question becomes whether the amount of pollutants that are being brought into the embayment areas is in such concentrations that they tend to cause problems along the shoreline, especially as it pertains to dissolved oxygen levels. From the facts presented, this outcome is not expected. Levels of dissolved oxygen in the St. Johns River can vary in the natural condition as much as 2 to 3 mg daily. These variations are influenced by algal activity and are not uncommon in Florida waters. Dissolved oxygen is essential to aquatic life. Optimum levels of dissolved oxygen for the fish population of the river are in the neighborhood of 6 to 8 mg/L. DER has established a minimum DO standard of 5 mg/L for Class III waters such as Trout Creek, Palmo Cove and the St. Johns River. This standard is designed to achieve uniform compliance throughout water column at whatever time the measurement may be made. DER, by the employment of this rule, is attempting to deal with those instances in which, in view of the dissolved oxygen level, aquatic organisms are placed under greater stress. The lowest DO concentration expected is normally seen in the summer in July, August and September. DO concentrations in the water column are expected to be highest at the surface area and lowest near the bottom. Measurements near the bottom are significant in this instance because the discharge will occur approximately one foot off the bottom of the river. The Applicant took DO measurements of the area in question during the spring of 1984 over a period of three days. These measurements were taken at a time when a better quality of dissolved oxygen might be expected as contrasted with circumstances in the summer. With the amount of wind involved impressive levels of reaeration were also occurring. These measurements showed that in all stations DO levels were at least 5.0 mg/L at all depths. A study by Applicant's consultant Environmental Science Engineering related to a diurnal event for dissolved oxygen was taken approximately one kilometer downstream from the point of discharge in August 1985 and did not reveal any measurements below 5.0 mg/L. The river was choppy on that day and this would improve the quality of dissolved oxygen. Historical data by DER related to water quality at Picolata, which is south of the POD in the St. Johns River, reveals average DO levels of approximately 6 mg/L. Historical water quality data collected by the Florida Game and Freshwater Fish Commission near Green Cove Springs, which is several kilometers north of the point of discharge, indicated average DO levels in compliance with water quality standards. Diurnal data from near Green Cove Springs did not show any history of DO values below the state standards. There is other historical data, however, which indicates that DO concentrations in the general vicinity of the point of discharge do go below 5.0 mg/L. Game and Freshwater Fish Commission data indicate that the readings below 5.0 mg/L could occur as much as 10 percent of the time. This relates to the study done at Green Cove Springs. There does not appear to be any particular pattern to these events of low DO violations other than the expectation of their occurring in the summer months, occurring more frequently in the lower depths of the water column and in areas which are shallow with limited flow. The summer circumstance is one in which there is a possibility of very heavy rainfall followed by hot weather with overcast skies and no wind, and the DO values go down in that set of conditions. The DO values are, in addition to being lower near the bottom of the water column, likely to be lowest in the evening or early morning hours and persist in length of time from eight to ten hours. Some of the Florida Game and Freshwater Fish Commission data from Green Cove Springs depicted some DO concentrations as low as 1.8 mg/L at the bottom and 2.1 mg/L at the surface. The low readings that were taken at Green Cove Springs occurred in September 1979 after Hurricane David had created unusual conditions in the upper St. Johns River as to effects on DO. The same report indicated DO concentrations at eleven stations in the lower St. Johns River in July and September 1982 were in the range to 4.0 to 4.5 mg/L respectively. This particular data is not particularly valuable in view of the location of those stations. There are occasions when the DO concentration at the point of discharge could go below 5 mg/L and could be as low as 2 mg/L on the bottom, but this is not a routine occurrence and would not persist. The Petitioners' consultant Young had taken certain dissolved oxygen readings at the point of discharge in April 1985 and found compliance with the 5 mg/L standard. At other times he and the consultant white measured substandard dissolved oxygen concentrations at the point of discharge. On July 20, 1985, white collected water samples at the surface and at two feet above the bottom and determined that the readings were 4 mg at the surface and 3 mg near the bottom. On August 10, 1985, Young measured DO concentrations of 4 mg/L near the bottom. On August 30, 1985, Young measured DO values of 4 mg/L at the point of discharge. Young had also measured DO concentrations at Green Cove Springs on August 10, 1985, and discovered readings as low as .5 mg/L and ranging up to 3.8 mg/L. A downstream measurement away from the point of discharge in the main channel made on August 10, 1985, by Young showed a dissolved oxygen reading of 4 mg/L. In these August measurements Young had discovered a number of readings that were in compliance with the 5 mg/L requirement. Again on September 5, 1985, Young made a measurement of dissolved oxygen near the bottom of the water column at the point of discharge which was 5.3 mg/L. Young's measurements of dissolved oxygen at the surface and in the intermediate depth, typically were above 5 mg/L. Bottom readings taken by Young in the main channel of the river and to some extent in the embayment areas were extracted from the soft detrital materials, the place of intersection of the river bottom and the water column. DO levels in these anoxic materials would tend to give lower dissolved oxygen readings and, to the extent that this anoxic material remains in the test probe while taking measurements toward the surface, would have an influence on the readings, making them appear lower than would be the case if the anoxic sediments were not present in the test device. These effects were not so dramatic as to cause the rejection of the data collected by this witness. Some explanation for lower DO readings at the point of discharge can be attributable to the fact that the anoxic material associated with high benthic oxygen demand on the bottom reduces the dissolved oxygen in the water column. Although Rangia clams were present at the point of discharge and they are capable of living in an environment of low salinity and low DO, they are likewise able to live in higher ranges of DO and their presence cannot be regarded as meaning that the dissolved oxygen levels are consistently below 5 mg/L. Petitioners' consultant White opined that there would be a very frequent violation of DO standards at the point of discharge, approaching 25 percent of the time. Considering the facts on the subject of dissolved oxygen in that area, this opinion is rejected, as is the opinion that DO concentrations will go below DER standards most of the time in July, August, and September. Young believes that a more involved study of worst case conditions would reveal DO violations throughout the column in the center of the river. The data that was presented was ample to demonstrate that violations would not be that widespread. Nor is the opinion of the consultant Parks on the subject of DO violations, to the effect that they will occur on many occasions accepted. In the Palmo Cove area it is not unusual to see some DO readings below the 5 mg/L standards. The E.S.E. group found substandard DO conditions in Palmo Cove at sampling Station 1 in September and October 1984 and some instances in April and May 1985. DO concentrations were found in the range of .4 and .6 mg/L in August 15 and 30, 1984, respectively, with DO concentrations of 1.8 and 2.1 mg/L reported on October 4 and October 29, 1984, respectively. DO violations in four out of eight checking periods between April 25 and May 24, 1985, were shown in the Palmo Cove area. Measurements taken by the consultant white showed 3 mg/L at the surface and 2 mg/L at the bottom on July 28, 1985. The consultant Young also made a measurement of 3.2 mg/L of dissolved oxygen on August 10, 1985, in a mid-depth reading in the Palmo Cove area. On September 5, 1985, he found a DO reading of 4.0 mg/L. At those places along the eastern shoreline of the St. Johns River and the relative vicinity of Florence Cove, Jack Wright Island, Little Florence Cove and Colee Cove, low dissolved oxygen readings were found, that is below 5 mg/L. These coves can be expected to have substandard readings frequently during the summer period, based upon measurements taken by the consultant Young. In the conduct of the drogue study related to the Chlorox bottle, the consultant Young in tracking the path of those bottles, found a couple of locations in the path of the drogue which were in the range 2.8 to 4.2 mg/L and 2.0 to 4.6 mg/L. The influences of the discharge will not reduce DO in the embayments. The ambient conditions for BOD in the area where the discharge is contemplated is relatively low and there is no thermal or saline stratification even in the summer months. Nutrient concentrations in this part of the St. Johns River are as indicated within the Applicants Exhibit A-4(B)(3) and at present are at such levels as to promote a healthy fish community. There is algae production that can be sufficient in some areas within this section to cause algae blooms. Algae blooms are not found to be a routine occurrence. Algae blooms reflect higher levels of nitrogen and phosphorus. The consultants Young and White have seen algae blooms in the St. Johns River away from the general area of concern, both upstream and downstream. Should those algae blooms occur, they would promote significant rises and falls in DO concentrations. In Palmo Cove and the St. Johns River, supersaturated DO concentrations have been detected and they are indications of high rates of primary algal productivity. The circumstance of supersaturated conditions, related to dissolved oxygen, can be the by-product of an algal bloom. The concentrations of nitrogen range from an average of 1.42 to a maximum of 2.54 mg/L. Nitrogen concentrations of 1.4 mg to 1.5 mg/L are optimally advantageous for fish production. Significant increases above those levels would cause the decline of the fish population. Total phosphorus concentrations in the ambient waters are high. Concentrations in excess of 0.1 mg/L of total phosphorus are regarded as a indication of eutrophication and the average concentration here is measured as 0.3 mg/L with a maximum ambient concentration found at 0.52 milligrams per liter. There is significant algal growth in the inshore areas and an indication of some eutrophication in the grass beds. The dominant species of algae found in that vicinity are blue-green, which are seen as being nuisance species. The grass beds along the shoreline are basically healthy. On the other hand, some of the public witnesses identified the fact that grass beds and other vegetation have died with the advent of discharge from the Applicant's plant into Trout Creek. This was under a system in which little or no treatment was afforded the effluent. One other public witness indicated that his dock in the Florence Cove area had been covered with a slimy material and algae during the past two years. Significant grass beds are found along Jack Wright Island and in other areas along the eastern shoreline of the river. These grass beds are important as fish habitat to include nursery areas, areas for various juvenile species of fish and other organisms. Some of these grass beds are showing signs of environmental stress, and nutrient loading can contribute to that stress. Some of the grass beds are covered with higher amounts of algae, duckweed and periphyton than are desirable. The duckweed had floated into these areas from other locations and can be expected to move away. The presence of algae is an indication of nutrient loading. The presence of duckweed is not a product of nutrient loading in the sense of the production of the duckweed at the site where they were found along the shoreline. The area in question between Pacetti Point and Shands Bridge serves as a nursery in a sense of providing habitat for juvenile species of fish and other organisms. The grass beds along the shoreline provide habitat for feeding and breeding related to juvenile organisms, to include such species as bass and shrimp. Juvenile catfish are found within the deeper portions of the river as well as croaker and other marine species. There is a high number of juvenile blue crabs in this area of the river and this is a commercial resource. Shrimp are taken by recreational fisherman in the area of the North Shore Pacetti Point. Clam beds are also present near the point of discharge. Juvenile and adult manatee have been seen in the St. Johns River and in the area near Jack Wright Island. Manatee have also been observed in Trout Creek at a time before the operation of the Applicant's plant and at times following the cessation of operations in June 1985. During the course of the operation of the Applicant's plant, when raw effluent was discharged into Trout Creek, fish kills were observed. Those events had not been seen prior to the operation of the plant. Indications are that fish were killed in the creek due to the use by the Applicant of fly bait, which made its way into the water. Dispersion Modeling of Water Quality Impact In order to gain some impression of the influences caused by the dispersion of the pollutants within the effluent, the Applicant through its expert employed several modeling techniques. DER was made aware of this modeling as it developed. A far-field model was used to calculate what the long-term or steady state impacts of the treated effluent would be on the ambient water quality. In trying to identify the influence of the discharge, measurement of metals were taken based upon an assessment of long term increases. BOD, which breaks down and consumes oxygen over time, was examined in the sense of the long term effects as to DO deficits. In essence these projections were superimposed over the ambient condition to gain an impression of the adjusted ambient values, taking into account the influence of the discharge. The Applicant also ran a plume model which was designed to calculate spreading and dispersion of the treated effluent within the zone of initial dilution or mixing zone at the point of discharge. This model responds to the discharge configuration. Through the use of computer calculations, it was established that a five-point diffuser with port openings of 0.75 inches in diameter angled upward at ten degrees would result in an effluent dilution ratio of 28.5:1 within two meters of the point of discharge. The calculated impacts of the plume model were superimposed upon the adjusted ambient water quality conditions set forth in the far-field model in order to determine net impact upon the receiving waters within the mixing zone. A third model was used, referred to as the lateral diffusivity model. This model is designed to calculate the six-hour or short term water quality impacts of the treated effluent when it moves from the zone of initial dilution during flood and ebb tide conditions. By estimating dispersion rate, this model predicts what dilution would occur in the path of the effluent plume. These impacts were then superimposed upon the adjusted ambient water quality conditions to determine the total impact in the path of the plume. The modeling work by the Applicant's consultant is a reasonable depiction of the predicted impacts of the pollution on the ambient conditions. The calculations used in the far-field model assumed a freshwater flow of 2,000 CFS. This assumption in the far-field model satisfactorily addresses worst case flow conditions related to seven-day, 10-year low flow. The temperature utilized in depicting ambient water was 30 degrees centigrade when employed in the far-field and lateral diffusivity models. This corresponds to warm weather conditions, which are more profound in describing effects on water quality. The far-field and lateral diffusivity models assumed that the treated effluent discharged from the pipeline would have a BOD concentration of 665 mg/L. This is contrasted with the maximum concentration allowed by the draft permit, which is 510 mg/L, which is the expected amount of BOD. This tends to depict the impacts of the discharge more conservatively. The model assumes the BOD loading of 2,720 kg per week, equating to an average discharge concentration of 665 mg/L if the plant operates five days a week on an eighteen-hour day. The reaeration rate and NBOD and CBOD decay rates used in the far field and lateral diffusivity models are acceptable. Likewise, the longitudinal dispersion coefficient that was used in the far-field model is acceptable. The standard modeling methodology in this process calls for an assumption of a 1.33 growth rate of the plume in the lateral diffusivity model. The Applicant's consultant decided to use a lower constant diffusivity growth rate. As a consequence, less lateral spreading is depicted. With less lateral spreading, less dilution is shown, and the impacts predicted by the model are exaggerated. One of the parameters of the plume model has to do with river flow which causes some turbulence and also brings about dilution. In this instance the plume model calculations assume stagnant conditions which is a more conservative assessment. As the Petitioners have suggested, the modeling to explain the impacts of dispersion of the pollutants is not designed to give precise calculations of the DO deficit at each point in the river along the eastern shoreline. It is indeed an estimate. The estimate on this occasion is reasonable. Although DER performs mathematical analysis of dispersion of proposed discharge in some cases, it did not do so on this occasion. Nonetheless DER was satisfied with the present choice for modeling the dispersion characteristics of the discharge. Although the models utilized were not subject to exact calibration by measurement of the dispersion at the site, the information gained by the Applicant prior to the imposition of the modeling techniques was sufficient to develop the models and to give a theoretical verification of the expected impacts from the discharge. The Applicant's belief that the maximum DO deficit caused by the discharge will not exceed 0.1 mg/L is accepted. The dissolved oxygen level in the effluent at the point of discharge will be above 5 mg/L. The Applicant's choice of reaeration rates, CBOD decay rates, NBOD decay rates, discharge rate from the pipeline, hours of operation, average reversing current speed, net non- tidal flow, non-tidal velocity, time lag before NBOD decay, maximum tidal velocity, and other variables and assumptions within the models were acceptable choices. Although the possibility exists of an occasional 5 1/2 day operation in which 10 additional hours of operation are added, this would not be so significant as to set aside the predictions as to the pollutant dispersion. The Applicant's consultant who modeled the dispersion rates did not conduct dye studies to verify or calibrate the actual dispersion in the river. One of the dye studies indicated a lateral spreading rate which was less than that predicted by the model. Notwithstanding this revelation, the overall techniques used by the Applicant in predicting lateral spreading rate are sound and do not present a risk of a greater DO deficit than was predicted based upon incorrect assumptions as to lateral spreading rates. The Applicant's consultant's use of 2,000 CFS as the net non-tidal low flow was a more convincing estimate than the field data collected by the United States Geological Service, given the paucity of information about the flow conditions within the St. Johns River. The Applicant's choices in describing maximum tidal velocities and average velocity are accepted. The critique of the modeling efforts done by the Applicant that was made by Petitioners' consultant, Dr. Parks, in which he concludes that the DO deficit is considerably greater than 0.1 mg/L is not accepted. Comparison of Predicted Impacts of Discharge with Statutory and Regulatory Criteria Inside the Mixing Zone Applicant's assumptions about the increase in nutrient concentrations in the St. Johns caused by the discharge are accepted. This is based on the assumption of a nitrogen value of 52 mg/L which was achieved in bench scale testing of the effluent and which can be achieved in the full scale operation. As the effluent is discharged from the diffuser within the mixing zone, there will be some turbidity problems in that the bottom near the point of discharge. The soft silt there is easily resuspended. When the discharge is concluded, the material will settle back to the bottom. There will be further resuspension when the operation commences again and there is a discharge. The transport of these suspended materials is limited in that the water velocity associated with the discharge is quickly dissipated. This phenomenon will not cause adverse environmental impacts. The mixing zone does not include an area approved by the State of Florida, Department of Natural Resources for shellfish harvesting; it does not exceed the presumptive maximum size set forth in Rule 17-4.244, Florida Administrative Code. Nor does it include an existing drinking water supply intake or any other existing supply intake that would be significantly impaired by the proposed mixing zone. The water in this area is of sufficient depth that it will not support grass beds that are associated with a principal nursery area, such as pond weed, midgeon grass, manatee grass, turtle grass or eel grass which are used to support nursery activities. These grasses are normally found inshore. Although juvenile fish are found throughout this reach of the St. Johns River, and for that matter in the entire lower eighty miles of the St. Johns River, the mixing zone is not of such dimensions that it will preempt the health of juvenile fish. Most of the freshwater fish in this system use the littoral areas for reproduction. Marine and estuarine species do not reproduce in the St. Johns River. There is some reproduction that is occurring with some species, such as catfish. Given the size of the mixing zone, no significant adverse effects will occur with the established community of organisms in this portion of the river. The mixing zone will not otherwise impair designated uses of the St. Johns River. The treated effluent will not create a nuisance condition or violate any other DER standards that apply within the mixing zone. With the advent of the full scale facility, maximum, average and chronic toxicity criteria can be reasonably expected to be met at the point of discharge, within the mixing zone and at the boundary of the mixing zone. As described before, the effects of sediment transport upon discharge are localized. The proposal for a mixing zone takes into account Rule 17-4.244, Florida Administrative Code, in the sense of addressing present and future sources of pollutants and the combined effects with other pollutants or substances which may be present in the ambient waters. One of the concerns which DER has about wastewater is the effect which that pollutant has on organisms within the environment. To gain an impression of that influence, testing is required to establish whether the wastewater is acutely toxic. The testing is known as bioassay assessment. While this assessment is normally done after the grant of a construction permit, when confronted with uncertainty about the quality of the effluent, some testing is beneficial prior to the grant of a construction permit. This is especially true given DER's experiences in dealing with raw effluent of several of the scallop processors, to include Homer Smith, which showed that the raw effluent was acutely toxic. This acute toxicity testing is done by placing test organisms into aquaria containing the effluent and measuring survival of those species over time. Results are described in terms of a measurement of the concentration of the effluent at which 50 percent of the organisms are killed during a prescribed test period. In static testing the organisms are simply exposed to the effluent for the requisite period of time. By contrast, a static renewal test calls for the effluent to be replaced with another sample of the effluent at various intervals within the test period. Finally, a flow through bioassay test calls for a continuous stream of fresh effluent to be introduced in prescribed concentrations over the duration of the test. A bioassay assessment in the static condition was performed related to DAF pilot scale effluent that was collected on April 19, 1985. In this instance Daphnia magna were used as test organisms and demonstrated a survival rate of greater than 50 percent in a 100 percent concentration of effluent over a period of 96 hours in the setting of static and static renewal tests. That survival rate was also shown in lesser concentrations of effluent as well. The April 19, 1985, sample was also used in testing the response of Pimephales promelas. These test organisms did not survive either in the static or static renewal tests. While an hypothesis has been made that acute toxicity was experienced in this test organism attributable to build-ups of ammonia, which is greater with this type of organism than with the Daphnia, due to larger biomass which allows for a greater number of ammonia generating bacteria to be presented in the test aquaria and the fact that the Pimethales excrete more ammonia, these differences do not definitely explain why the Daphnia survived and the Pimephales did not. In the series of static renewal bioassays performed on the wastewater that was collected at the plant on April 29, 1985, and shipped to Lenox, Massachusetts, for bench scale treatment, the test organisms of both types failed to survive for 96 hours. It was discovered that during the course of the test period, levels of ammonia rose rapidly. Trace metals in the treated effluent are principally in the form of stable species, as opposed to free ions. These constituents standing alone are not likely to have caused the mortality in the test organisms. The effect of decomposition of the organic constituents in the waste stream is the most likely explanation of why the bioassays of pilot and bench scale treated effluent did not lead to a satisfactory result. Unionized ammonia, a by-product of organic decomposition, is found to be a principle player in the explanation of why the treated effluent was acutely toxic to the test organisms. The exact cause of toxicity has not been precisely identified. Given the complex nature of the effluent, other potentially toxic substances such as sulfides, amines, and other organic compounds could have contributed to the demise of the test organisms. Moreover, toxicity can increase with combinations of chemicals acting in a synergistic fashion, making their combined effects more devastating than the effect of any single substance. Having in mind the fact that ammonia is a major problem in the survival of test organisms subjected to a bioassay, the question becomes one of what may be done to remove ammonia. The production of ammonia in wastewater would depend upon the presence of bacteria. The proposed DAF system removes substantial numbers of bacteria, thereby limiting the possibility of ammonia build-up, if bacteria are not allowed to recolonize in some part of the system prior to discharge. As discussed before, reduction of bacterial activity can be achieved within the proposed treatment system. This is unlike the experience with the bench scale and pilot scale testing that was done on the effluent in which a substantial amount of time transpired before subjecting the test organisms to the effluent and in which a substantial amount of time transpired while the test organisms were being subjected to static and static renewal procedures with the same effluent. The time intervals contributed to the build- up of toxic levels of ammonia in the effluent. The system which is proposed in this instance can avoid the problem of time as it relates to the build-up of levels of ammonia. To further reduce the influence of retention of the waste product, flow through bioassay testing would be the most appropriate measurement of the survivability of the test organism in that it would be responding to real case conditions pertaining to the quality of effluent and its potential toxicity. Under these circumstances, it is reasonable to believe that in a flow through bioassay test of the full scale treatment system, the test organisms could survive. This determination is reached given the reduction in retention time compared to the bench and pilot scale testing, which reduces ammonia, with further ability to reduce ammonia by frequent removal of residual materials from the sludge drying bed and sump pit and taking into account basic improvements in treatment efficiency associated with the full scale system. In addition, the pH of the effluent can be regulated to avoid toxicity in the ammonia which is associated with inappropriate balance within the pH. While a 96-hour LC-50 cannot be calculated with the results of bench scale and pilot scale testing, a reasonable possibility exists for the establishment of that measurement with the advent of a flow through bioassay. There is sufficient similarity between the effluent in the pilot and bench scale testing and the expected effluent in the full-size system for the bioassay testing that was done in those limited systems to give a meaningful indication of the probability that the Applicant can pass a flow through bioassay. Applicant can be reasonably expected to produce an effluent in the mixing zone which will not exceed the 96 hour LC-50 for acute toxicity. As with the circumstance of ammonia, pH can be controlled within the system to address the implications of changes in pH as it pertains to other pollutants in the wastewater. Ammonia production can be influenced by the amount of alkalinity in the effluent and the receiving waters. Alkalinity has not been measured thus far. Alkalinity could be established for the effluent and receiving waters and dealt with if it was suspected as being an explanation of problems with the build up of ammonia which might exceed DER standards. The discharge from the Applicant's plant will not cause long-term problems with low DO, high nutrients, algal imbalances, and chronic toxicity. Outside the Mixing Zone Those constituents within the waste stream, to include those for which a mixing zone was sought, will comply with applicable water quality standards at the boundary of the mixing zone. The dissolved oxygen deficit at its maximum can be expected to be in the neighborhood of 0.1 mg/L and will be exerted somewhere in the range between 1 and 2.5 km downstream of the point of discharge across the width of the plume in worst case conditions. This deficit is not of a dimension which is easily detectable. The implications of that deficit are difficult to perceive in terms of tangible environmental consequences. While a deficit in the range of 0.1 mg/L has some relevance in the DER permitting decision, that deficit as it is dispersed is not expected to cause or contribute to violations of water quality standards in the main channel of the river or in the inshore and embayment areas. While it is true that there are periodic fluctuations of dissolved oxygen below 5 mg/L, DER, as a matter of present policy and professional judgment believes that in this system which evidences characteristics of a clean well-flushed, unstratified water body occasional readings of low DO are not regarded as an indication of violation of water quality standards. This speaks to the main channel area of the river where the only quantifiable influence is expected. The facts presented in this case support the soundness of this policy choice. Petitioners presented the testimony of former officials within DER, namely Parks and Young, who stated that dissolved oxygen standards of 5 mg/L are applied at all times and at all places. They felt that the DER policy was to the effect that permits would not be granted for discharge in any circumstance where the DO concentrations are substandard in the ambient waters, regardless of the amount of decrease or deficit that would be promoted. Parks spoke of the availability of site specific alternative criteria, variances, exceptions or exemptions from the terms of the water quality rule. Having considered these remarks, the present DER policy of allowing the permit to be granted in the instance where occasional violations of ambient water quality standards related to 5 mg/L occur, in the face of the small deficit which is involved in this case, is the better choice. Further, it is a choice that is not so inconsistent with prior practices as to be arbitrary in nature. Finally, DER's position that it would be unadvisable to require a request for site specific alternative criteria, variances, exceptions or exemptions in circumstances such as this case is accepted, when taking into account the problems which would be presented to the agency in administering the permit program, should each Applicant who is confronted with occasional violations below standards for dissolved oxygen have to seek extraordinary relief. While the facts do identify that some pollutants can reach the embayment areas on the eastern shore, the facts do not depict a circumstance in which the amount and quality of that effluent will be such that it will cause or contribute to dissolved oxygen violations in those areas. The water quality in the embayment areas is lower than that in the main area of the river due to inadequate flushing. The areas inshore do not interact with the main channel in a way that would take advantage of the faster moving currents found in the main channel as this interaction might promote a better quality of water. In view of the situation in the embayment areas, the Applicant, on advice of his consultants, moved the proposed location of the discharge into the main channel away from the areas which were under greater stress in terms of dissolved oxygen values and in doing so avoided damage to these areas. The current velocities in the area east of the main channel are weak. There is a substantial distance from the point of discharge to the inshore areas. As the effluent moves toward the inshore or nearshore areas it will become so diluted it will not have an adverse influence on dissolved oxygen. Not only the distances involved, but also the fact that water flowing near the surface is well aerated contributes to the dilution of the effluent as it approaches the shore. Although it has been shown that some stress in the grasses along the eastern shoreline has occurred and the existence of blue-green algae has been shown, together with indications of undesirable algal production, the nutrients which are part of the effluent at the point of discharge are not expected to cause an imbalance in the natural populations of flora and fauna or create nuisance conditions or violations of transparency standards. The nitrogen increase could cause an increase in algal production in the order of one percent, which is inconsequential. The treated effluent will not adversely effect biological integrity of the St. Johns River. The benthic microinvertebrate community in this part of the river is fairly low density due to the fluctuations in salinity levels and predation by fish and blue crabs and given the nature of this substrate which is unstable with low levels of dissolved oxygen. The organisms that are predominant have a tolerance to siltation and fluctuations in dissolved oxygen. The treated effluent will not adversely effect the microinvertebrate community. Petitioners point out the fact that when DO concentrations decrease below optimum levels, fish and other organisms suffer. The fish reduce their movement, feeding and reproduction and they are less disease resistant. They are placed in a position of having to leave the area or risk death if the impacts of the decrease in dissolved oxygen are severe. The influence of the effluent at the point of discharge in this project is not expected to have significant impact on fish and other organisms within these topics of concern expressed in the paragraph. Even though the dissolved oxygen deficit extends in amounts below 0.1 mg/L as far as 2.1 km upstream and 4.5 km downstream and within a wide breadth of the center portion of the river, those deficits will not be significant to the water quality. The BOD associated with the discharge, allowing for mixing will not depress dissolved oxygen levels below DER standards of 5 mg/L. The combination of BOD and nutrient discharge will not cause an imbalance of algal production in the river, nor will it contribute to the dominance of nuisance algal species. The BOD nutrient loading associated with the discharge into the St. Johns will not promote significant ecological impacts on the St. Johns River, to include the possibility of more frequent and severe algae blooms, increase in benthic oxygen demand, risk of increase eutrophication, destruction of grass beds or decline in the fishery. With the advent of discharge in the St. Johns DO fluctuations in the river will not be greater nor will there be an occurrence of a swing from substandard dissolved oxygen levels to supersaturated dissolved oxygen. While the discharge from the Applicant's plant contains pollutants such as cadmium, zinc, arsenic, copper and organic decomposition products, the treatment provided the wastewater is expected to overcome any acute toxicity associated with these materials individually or in combination. Chronic toxicity is not expected related to these materials. The effects of these materials are not expected to cause physiological and behavioral responses which are abnormal in organisms such as reduced locomotion and reproduction or increase susceptibility to diseases to include ulceration and increased mortality. Treatment contemplated and provision of a mixing zone will allow compliance with the standards related to cadmium. Reference has been made to a development known as St. Johns Harbor which is in the vicinity of the proposed discharge and can be expected to promote some pollution in Palmo Cove and the St. Johns River. Although St. Johns Harbor development is proceeding through stages of permit review, it does not appear that it has reached a place in which exact information about its implications as a pollution source can be set out. In discussing the St. Johns Harbor Development, Petitioners emphasized that this eventuality and other matters which deal with cumulative impact have not been satisfactorily addressed. There is no indication than any other substantial development or activity other that St. Johns Harbor is contemplated in this area associated with the permit review at hand. St. Johns Harbor eventually hopes to develop 3000 residential units. It has received the approval of the Northeast Florida Regional Planning Council for the initial phase of development. It has been reviewed by the Florida Fresh Water Game and Fish Commission. The developers are proceeding with the project to include the sale of lots. Nonetheless, that development has not reached the phase where its implications would form the basis of a denial of this project based upon the theory of cumulative impact. While Petitioners contend that stormwater runoff from the St. Johns Harbor project will be a problem, assuming an inadequacy in the design which that developer employs to deal with that matter, this eventuality is not expected based on a review on the facts presented. Reference is made to the Ulcer Disease Syndrome which fish in the St. Johns have suffered from. The principal area in which this event has occurred is north of the area expected to be influenced by this discharge. Nonetheless, diseased fish have been found in Palmo Cove. This Ulcer Disease Syndrome is caused by heavy metals and hydrocarbons, and these materials act in league. The advent of additional heavy metals and other pollutants, such as those being discharged from the Applicant's plant could cause further deterioration in the condition of fish suffering from Ulcer Disease Syndrome. Having considered the facts, this outcome is not expected. Ambient levels of 18 other pertinent pollution constituents in the vicinity of the point of discharge were ascertained by the Applicant's consultants on the basis of field observations and historical United States Geological Survey and Florida Game and Fresh Water Fish Commission data. This formed a basis of an assessment of average and worst case values. This information indicates compliance with those parameters for purposes of water quality standards at the point of discharge. Implementation of Construction Permit Permit Conditions Applicant's Exhibit A-10 is a copy of the DER intent to issue the construction permit. It sets forth seventeen specific permit conditions, and these conditions should be imposed in the permit. The following are additional conditions that should be set forth in the construction permit: The operation and maintenance manual required by original Condition 10 shall provide that the DAF treatment system be cleaned regularly with a mild chlorine solution and that the wastewater from this maintenance be placed in a vehicle and carried off the premises for disposal at an appropriate location. This wastewater from the cleanup shall not be discharged from the plant into state waters. The operation and maintenance manual shall provide that a dosage level of chlorine to clean the pipeline that will result in comp- liance with all water quality standards at the end of the pipeline be added to a fraction of fresh water used to flush the system at the cessation of discharges each day. DER must approve this dosage amount before it becomes part of the operation and maintenance manual. The operation and maintenance manual shall set forth a regular schedule for pumping the accumulated sludge or solid materials from the sump pit. The operation and maintenance manual shall provide that as much as 50 gallons per minute of fresh tapwater may be added to recycled wastewater for pressurization. Any discharge created with this addition may not exceed 250 gallons per minute. Any discharge created above 200 gallons per minute shall be consti- tuted only of tap water. Two machine scallop processing operations at the plant will be limited to an average of 18 hours per day and no more than 90 hours in a week. Monitoring in Trout Creek shall continue as specified in paragraph 17(E) of the Consent Order as long as discharges into Trout Creek continue. On each occasion when the DAF treatment system is in operation, the Applicant shall have a fully trained operator on site. The terms of the construction permit shall expire on December 31, 1986. The constructed pipeline shall be leak tested once a month from June to September and every other month during other months of the year. If a leak in the pipeline is detected it shall be repaired within 20 days and retested for leaks within 15 days thereafter. The carrying out of any leak testing and repairs shall hereunder shall be certified by a professional engineer. Pre-pipeline Operations Petitioners have pointed out the fact that when two or more pollutants are present, as in the instance of the effluent discharged by the Applicant's plant, those pollutants tend to act in a synergistio manner. That can exacerbate the circumstance where you find low dissolved oxygen. This is particularly a matter of concern when discussing Trout Creek. This is unlike the impacts of the discharge into the St. Johns River which are not expected to exceed standards or promote adverse effects. The implications of operation within Trout Creek to allow necessary permit review by DER and the State of Florida, Department of Natural Resources can be overcome once the discharge is withdrawn from Trout Creek and may be addressed by DER more immediately if the dissolved air flotation unit, after a reasonable period of adjustment, does not perform in the fashion that it appears to be capable of. In the instance of discharge into Trout Creek, the material discharged tends to remain in that area for a relatively long period in that the creek is small and has very little flow and poor flushing characteristics. DO levels will be depressed, the presence of a deficit in dissolved oxygen caused by the discharge from the DAF unit would increase the probability of fish kills when contrasted with a circumstance where there is no further deficit of dissolved oxygen. Given the explanation of why a fish kill occurred based upon the past use of fly bait by the Applicant and the fact that there is no indication of fly bait in the present plans, a fish kill in Trout Creek in the time of interim discharged does not seem probable. With the advent of discharge into Trout Creek, the possibility is enhanced for algae blooms and increased eutrophication. There would also be some accumulation of toxic substances. Additionally, there would be some influence on juvenile fish which are more sensitive to pollutants and the possibility exists that it could reach levels that are lethal to bass larvae and juvenile sports fish. The creek would lose some of its viability as a nursery and some fish would leave the creek. These events are not irreversible and can be reasonably remedied with the cessation of discharge into the creek. Moreover, as in the instance with the problem with fish kills, if some set of circumstances attributable to the discharge were to occur in such dimensions as to cause long term impacts in Trout Creek, DER could take action against the construction permit. Dissolved oxygen in Trout Creek can be below the 5 mg/L standard. Data of the E.S.E. group showed that at Highway 13 bridge, approximately fifty yards from the plant in December 1984 and January 1985, values were as low as 0.1 and 0.2 mg/L, and readings could be frequently below 2 mg/L at Highway 13. In April through June 1985, periodic surface dissolved oxygen concentrations were in the range of 3 mg/L and as low as 2.4 mg/L. DO concentrations generally found at the bottom of Trout Creek could be as little or lower than 1 mg/L at times. In July 24, 1985, at the time when the plant had not been operating for approximately a month, the DO concentrations were 2.9 mg/L at mid-depth and 0.8 mg at the bottom. Within Trout Creek in the area of the Pacetti marina, Consultant White measured DO concentrations in the range 1-3 mg/L. On August 10, 1985, six weeks after operations had stopped at the Smith facility, DO concentrations were found to be 3 mg at the surface, less at mid-depth and 0 near the bottom. Computer modeling was not done to ascertain the impacts of a discharge directly into Trout Creek from the DAF unit. The modeling done by the Petitioner's consultant, Parks, using some of the concepts considered in the Applicant's modeling for the St. Johns River is inapplicable to the circumstances in Trout Creek. Trout Creek has also served as a nursing ground for reproduction and habitat for young fish. During the course of the operations by the Applicant in the discharge of essentially untreated effluent, the beds of bass and sun fish have not been seen within the creek. Water quality improves with the DAF unit and sediment loading by heavy metals decreases. Trout Creek is a stressed system at present. It has low levels of dissolved oxygen, high nutrient concentrations and the presence of heavy metals in undesirable amounts. The low numbers of pytoplankton species give some indication of a highly stressed ecosystem. The present officials of DER, Palmer, Owen and Fox, expressed their concerns about dissolved oxygen in those instances where there would be a decrease in ambient DO concentrations. This has particular importance in discussing the problems associated with the discharge into Trout Creek, as opposed to the point of discharge contemplated in the St. Johns River, which risk is minimized given the characteristics of that area and the higher readings of ambient dissolved oxygen in that water, as contrasted with low readings within Trout Creek. A literal interpretation of the position of the agency officials would lead to the conclusion suggested by the Petitioners that no discharge should be allowed into Trout Creek, even on an interim basis. However, such a position would be inherently unfair considering the fact that some discharge would occur into the creek before the installation of the pipeline, whether based upon simultaneous permit review by DER and the State of Florida, Department of Natural Resources in the easement case or sequential review as is contemplated in this instance. Admittedly, the amount of time involved in the discharge into Trout Creek increases in view of the severance of the easement case from the present proceedings. This circumstance occurred in view of the desire on the part of the DNR to see the actual treatment efficiencies involved with the dissolved air flotation unit as opposed to the theoretical possibilities of that equipment. In the present situation, it would be a reasonable policy choice for DER to allow an interim discharge into Trout Creek pending the opportunity for DNR to monitor the quality of the effluent produced by the DAF unit and make a decision about the easement, thus allowing installation of the pipeline if the easement is granted. This arrangement contemplates that DER should closely monitor the quality of the effluent produced by the DAF unit, to make certain, after the Applicant has been given the opportunity to make necessary adjustments to that unit, that the Applicant is not allowed to continue to discharge into Trout Creek following this period of adjustment, when it is shown that the Applicant's equipment is not performing as expected. In any event, the discharge of effluent into Trout Creek will continue over a limited period of time and the system can be expected to quickly return to its healthier state after the removal of the discharge from Trout Creek. This has occurred in the past when the operations of the plant ceased and occurred at a time when the wastewater was of a more damaging quality than contemplated by that associated with the DAF unit. In summary, it would be a reasonable policy choice to allow the interim discharge into Trout Creek on this occasion. Dredge and Fill Permit Characteristics of Pipeline Corridor The pipeline corridor encompasses portions of Trout Creek, Palmo Cove and the St. Johns River. The bottom sediments where the pipeline is to be installed are constituted of soft, and sometimes extremely soft, flocculent silt. Although these sediments are easily resuspended, dispersement of these sediments will only occur while the pipeline is being installed. In placing the pipeline, it is the intention of the Applicant to simply allow the pipe to sink into the sediment. The soft substrate is several feet deep in some places within the proposed corridor. Nonetheless, the pipe is expected to stabilize as it sinks into the material. There are places within the corridor where a crusty material may be found on the surface of or just beneath the substrate. These are locations where jetting or mechanical excavation may be necessary. Jetting may also be necessary along the approximately 155 foot stretch of the corridor that crosses the State of Florida, Department of Transportation right-of-way. This requirement would occur in view of the fact that the Department of Transportation mandates that the pipeline be at a minimum of 30 inches below the creek bottom. In those instances where jetting or other mechanical excavation might be utilized, silt screens would be used to control the short term turbidity. In the areas within the pipeline corridor where tree trunks and branches have been found, these obstructions can be removed without incident. Taking into account the nature of the substrate, at the location where the diffuser will be placed at the end of the pipeline, special attention will be given to that installation to avoid having the diffuser settle into the soft silty material. Given the fact that the silty material is several feet deep and the related fact that the Applicant has not done specific testing of the depth, density and compressibility of this silty material, careful attention should be given to anchoring the diffuser and making certain that the exhaust ports within that device are correctly positioned. The need for this close attention is borne out by the fact that a test pipe which was placed in the silty material settled approximately two and a half feet within several weeks. The matter of the security of the diffuser is also critical, given the fact that the diffuser will be located within one foot of the bottom. Through proper installation, the Applicant can avoid having the diffuser settle into the silty material over time. The installation techniques satisfactorily address the potential problems. Projected Impacts (1) Environmental The icthyological and macroinvertebrate communities within the pipeline corridor have been examined by the Applicant in the person of his consultants. It was found that there are a variety of freshwater fishes within Trout Creek, such as large-mouth bass and sun fish, and a moderate density of macroinvertebrates. The St. Johns River proper is dominated by estuarine and marine aquatic organisms. Infaunal macroinvertebrate densities in the area of the pipeline corridor in the St. Johns River are not high. In placing the pipeline, the effects on aquatic and benthic communities within the corridor or upon water quality do not pose a threat to those communities or to water quality. During the installation of the pipeline, some disturbance of the benthic organisms can be expected; however, those organisms will be able to recolonize quickly. The mere presence of the pipeline is not expected to cause long-term impacts on biological resources or water quality. (b) Navigation In the area of the intended placement of the pipeline related to Trout Creek, boating clubs utilize that vicinity for purposes of anchorage. Those clubs have as many as twenty to thirty boats whose size varies from twenty to fifty-five feet in length. Some of those boats carry anchors which can weigh forty-five pounds or more. Typically, in anchoring one of these craft, the anchor rope is tied down and the engines reversed to set the anchor. Although testimony was given to the effect that the anchors being set might puncture the pipeline, given the explanation about the placement of the pipeline and the nature of the pipe itself, problems with puncturing the pipeline as it might interfere with navigation or environmental concerns such as turbidity plumes due to a puncture of the pipeline are not expected. Nor are the activities associated with retrieval of the anchors via the use of electric winches or hoists seen to be a problem in the sense of snagging the pipeline and rupturing the pipeline when the anchors are brought aboard the vessels. In summary, the pipeline will not be an interference to navigation in the sense of boat anchorage or other aspects of navigation associated with boating. Moreover, the Applicant is willing to indicate the location of the pipeline on navigational charts to assist boaters in avoiding potential problems with anchorage. This is a desirable arrangement and should be done. Comparison of Projected Impacts with Statutory and Regulatory Criteria The dredge and fill activities associated with the pipeline are not expected to cause long-term or short-term adverse impact on biological resources or water quality, or are they expected to interfere with the conservation of natural resources or marine productivity or interfere with navigation to such an extent to be contrary to public interest. The placement of the pipeline will not promote unacceptable interference with fish and other natural resources or destroy clam beds or grass flats, such as would be contrary to the public interest. Permit Conditions Appropriate permit conditions are as follows: Installation of the pipeline shall be conducted within Trout Creek only during weekdays. Pipeline installation activities within Trout Creek shall not block navigation. The pipeline shall be constructed within 60 days following the receipt of all necessary approval, to include the grant of an easement by the State of Florida, Department of Natural Resources for the placement of the pipeline over submerged sovereignty lands. All conditions set forth in the DER draft permit. See Applicant's Exhibit A-57.
Findings Of Fact The West Coast Regional Water Supply Authority (Authority) is authorized and obligated to acquire water and water rights, store and transport water, and deliver and sell water to its member governments for public use. The Authority exists pursuant to Sections 163.01 and 373.1962, Florida Statutes, and an interlocal agreement executed October 25, 1974, by the "member governments" which include the Cities of St. Petersburg and Tampa, and Pinellas, Pasco and Hillsborough Counties. The City of St. Petersburg is a member government of the Authority. St. Petersburg owns and operates a water utility system which receives water from the facilities at issue in this proceeding. Pinellas County (Pinellas) is a member government of the Authority. Under conditions experienced during the rupture of defective pipelines, Pinellas' water utility received water from the facilities at issue in this proceeding. The defective pipeline is still in use and Pinellas may again require water from these wellfields if another rupture occurs. The Southwest Florida Water Management District (District) is charged with the regulation of consumptive water use in west-central Florida, including all areas relevant to this proceeding. The District operates pursuant to the authority of Section 373.069, Florida Statutes. Hillsborough County (Hillsborough) is a member government of the Authority. Hillsborough owns and operates a water utility system which receives water from the facilities at issue in this proceeding. Pasco County is a member government of the Authority but does not receive water from the facilities at issue in this proceeding. The South Pasco wellfield is located within the boundaries of Pasco County. All parties have standing to participate in this proceeding. THE WELLFIELDS The South Pasco wellfield is located in southern Pasco County and is owned and operated by St. Petersburg. The South Pasco wellfield has been operating since 1973. Until 1977, the South Pasco wellfield produced approximately 15 million gallons per day (mgd) of water. The South Pasco wellfield was first permitted by the District in 1978. The permit was renewed in 1982. The current permit allows an annual average daily withdrawal rate of 16.9 mgd and a maximum daily rate of 24 mgd. The permit also requires that withdrawals from this field be balanced with the withdrawal levels of the Section 21 and Cosme- Odessa wellfields. The South Pasco wellfield is currently providing approximately 12 mgd to the Authority. St. Petersburg applied to renew the South Pasco permit on August 18, 1992. The application to renew the South Pasco wellfield was deemed complete by the District on April 28, 1994. No increase in the South Pasco wellfield maximum water withdrawal rate is being sought by the Petitioners. The Section 21 wellfield is located in northwest Hillsborough County. The Section 21 field is owned by St. Petersburg and jointly operated by the Authority and St. Petersburg. The Section 21 field has been operating since 1963. From the initiation of pumping through 1970, withdrawals varied between 10 and 18 mgd. The Section 21 wellfield was initially permitted by the District in 1976. The 1976 permit authorized the withdrawal of an annual average rate of 18 mgd and a maximum daily withdrawal rate of 22 mgd. The Section 21 wellfield currently operates under a permit issued in 1984. The permit effectively authorizes withdrawal of an annual average daily rate of 12 mgd and a maximum daily withdrawal rate of 22 mgd. The face value of the permit originally authorized an additional 1 mgd in the event that the developing Northwest Hillsborough Regional Wellfield could not produce sufficient capacity. The Section 21 wellfield currently provides approximately 10 mgd to the Authority. The Authority and St. Petersburg applied to renew the Section 21 permit on August 18, 1992. The applications to renew the Section 21 permit were deemed complete by the District on April 28, 1994. No increase in the Section 21 wellfield maximum water withdrawal rate is sought by the Petitioners. The Cosme-Odessa (Cosme) wellfield is located in northwest Hillsborough County, and like the Section 21 field is owned by St. Petersburg and jointly operated by the Authority and St. Petersburg. The Cosme wellfield has been operating since the early 1930's. At various times withdrawal rates at the Cosme field have neared 20 mgd. The Cosme wellfield was initially permitted by the District in 1976. The 1976 permit authorized the annual average daily withdrawal of 19 mgd and a maximum daily withdrawal of 22 mgd. The Cosme wellfield currently operates under a permit issued in 1984. The current permit authorizes an annual average daily withdrawal of up to 12 mgd and a maximum daily withdrawal of 22 mgd The face value of the permit originally authorized an additional 1 mgd in the event that the developing Northwest Hillsborough Regional Wellfield could not produce sufficient capacity. The Cosme wellfield currently provides approximately 10 mgd to the Authority. The Authority and St. Petersburg applied to renew the Cosme permit on August 18, 1992. The applications to renew the Cosme permit were deemed complete by the District on April 28, 1994. No increase in the Cosme wellfield maximum water withdrawal rate is sought by the Petitioners. The Northwest Regional Hillsborough wellfield (NWRHWF) is comprised of a vaguely linear series of wells located in northwest Hillsborough County and owned by the Authority. There is no actual Northwest Hillsborough "wellfield." The NWRHWF was initially permitted in 1984 for 8.8 mgd annual daily average and 18.4 maximum daily rate. The NWRHWF began production in the mid-1980's at a rate of approximately 8 mgd. The field currently produces close to 8.8 mgd, the maximum permitted withdrawal. The Authority applied to renew the NWHRWF permit May 19, 1994. Also included within the "wellfield" by the current permit application are two wells owned by Hillsborough County and operated by the Authority. The two wells are located at the Manors at Crystal Lake subdivision. The application for the Manors permit renewal seeks to combine the existing Manors permit with the NWRHWF and to allow the Authority to accept responsibility for the collection of wells. The Manors at Crystal Lake wellfield provide about .2 mgd to a residential subdivision. They are not in the vicinity of the NWRHWF. There are no common withdrawal or distribution facilities shared by the Manors at Crystal Lake wells and the NWHRWF. Hillsborough apparently intended to shed responsibility for the Manors wells and did not intend to be a co-permittee for either the Manors wells or the NWHRWF. Hillsborough specifically notified the District that the Authority would assume responsibility for the permitting of the Manors wells and that Hillsborough was withdrawing from the application process. Based on the Hillsborough representation, the District combined the Manors and the NWHRWF applications for processing and review. The 9 mgd withdrawal rate sought by the Authority in the renewal permit application is the sum of the existing permitted withdrawals at the combined wellfields and does not constitute an increase in existing withdrawal rates. The combined application was deemed complete by the District on June 21, 1994. The permit renewal applications at issue in this proceeding were timely filed in accordance with applicable deadlines. The evidence establishes that it takes from seven to ten years to bring new water supply facilities from the planning stage to operation. Otherwise stated, if the wellfields in these cases were to be closed, it would take up to ten years to bring new wellfields online. Public water supply permits issued by the District are typically valid for a period of ten years. On the subject permit applications, the Petitioners seek to have 20 year permits issued. There is no evidence supporting an extension of the District's standard ten year permit term. PREVIOUS WATER USE PERMITTING Prior to 1972, water withdrawals from the subject wellfields were unregulated. Beginning in 1972, the District established "regulatory levels" for the Cosme, Section 21 and South Pasco wellfields. Regulatory levels are measurements of the water pressure in the Floridan aquifer. As the pressure falls below the regulatory minimum, water withdrawals are restricted. Additional requirements were intended to balance the withdrawals from the three wellfields, an attempt to distribute the effects of large quantity water withdrawals on the water resources of the area. Although in the current permit application, the Petitioners originally sought to have regulatory levels established by the District removed from the renewal permits, the Petitioners have since abandoned the position and now suggest that the existing permits should be renewed with applicable regulatory levels intact. Beginning in 1975, the District initiated a permitting program. The Petitioners sought permits for the South Pasco, Section 21, and Cosme wellfields. Prior to 1989, District rules provided for the award of exemptions to permittees from meeting certain environmental criteria where such exemptions were "consistent with the public interest." The effect of the "public interest" exemptions was to permit withdrawal of water at rates which would otherwise have been prohibited and to allow water withdrawals to lower the Floridan aquifer. In 1975, the District issued the Section 21 and Cosme permits, and granted the "public interest" exemptions to the permittees, allowing water withdrawals which would otherwise not have met environmental permitting requirements. The permits were valid through the end of 1980. The initial South Pasco permit, issued in 1978, anticipated that withdrawals from the wellfield would be reduced when water from the Cypress Creek wellfield became available. The permit was valid through the end of 1980. In 1982, the South Pasco wellfield received a permit valid to September 1992. In 1984, the Section 21 and Cosme wellfields received permits valid to September 1992. The NWHRWF received its initial permit valid to September 1987. In all four permits, the District granted "public interest" exemptions to the permittees from meeting certain environmental criteria. The effect of the exemptions was to allow the water withdrawals at rates which would otherwise have been prohibited and which lowered the level of the Floridan aquifer. The District asserts that the Authority was advised during the early 1980's permitting process that alternative water resources needed to be developed to provide for future demand and allow for rotational capacity in the subject wellfields. The District asserts that little progress has been made in addressing these issues. To the extent the Authority was directed in prior and somewhat vague permit conditions to consider alternative sources, the evidence establishes that the Authority has complied with the minimal directives provided by the District. NORTHERN TAMPA BAY AREA HYDROGEOLOGY In the mid 1980's, the District declared the area of Northern Tampa Bay , including the subject wellfields, to be an "area of special concern" regarding the condition of local water resources. In 1987, the District undertook a water resource assessment project to examine local water resources. In 1989, based on preliminary information from the project (the "WRAP"), the District identified the subject wellfield area as the "Northern Tampa Bay Water Use Caution Area" in recognition of environmental stress identified by the District. After rule changes in 1989, the District eliminated the rule provision which provided for the granting of exemptions to environmental requirements. The amended rules required a permittee to assume responsibility for both on-site and off-site impacts related to the water withdrawal. The District also began to consider the "cumulative" impacts of withdrawals. At about the same time as the 1989 rule changes became effective, the District adopted the "Basis of Review" which provides for procedures and additional information related to water use permit review. In 1992, the WRAP study area was expanded and became identified as the "Northern Tampa Bay Water Resource Assessment Project" (NTBWRAP). The NTBWRAP is the District's most recent attempt at determining the condition of the water resources in the area of the subject wellfields. The geology of the wellfields and of most of the surrounding area is essentially a three-layer structure. The top layer is the surficial aquifer. The bottom layer is the Floridan aquifer. Separating the two is a "confining" layer. An "aquifer" is a geological formation in which water is stored and from which water may be obtained via the drilling of wells. The movement of water through geological materials is measured as "hydraulic conductivity." The surficial aquifer is primarily made of sandy, fine- grained material. The level of water found in the surficial aquifer is what is commonly described as the "water table." Generally, the level of water found in wetlands and lakes is a rough approximation of the surficial aquifer water table. The Floridan aquifer is a porous limestone formation with visible and sometimes sizable cavities and channels. The water of the Floridan aquifer permeates the limestone and flows within the limestone cavities and channels. The cavities and channels in the limestone are referred to as "karst" features, as are sinkholes, which result from the collapse of cavities in the limestone. The subject wellfields withdraw water directly from the Floridan aquifer. The confining layer between the aquifers is primarily made of clay. The impermeability and thickness of the clay deters the movement of water between the surficial and the Florida aquifers. The potential for movement of water between the aquifers is known as "leakage." The thickness of the confining layer in the area of the subject wellfields varies considerably. In some areas, there may be an essentially intact confinement and little or no leakage. In other areas, the confining layer is thin or nonexistent, and substantial leakage occurs. For example, the formations known as "sinkholes" are generally areas of collapsed Floridan aquifer limestone formations where the confining layer can be completely breached, at least until the sinkhole fills with other material and leakage is reduced. The level to which water will rise in a well drilled to the Floridan aquifer is known as the "potentiometric level." The water level identified through multiple Floridan aquifer wells is described as the "potentiometric surface." The potentiometric surface essentially measures the water pressure of the Floridan aquifer and can vary depending on factors including water withdrawals from the aquifer. The difference between the potentiometric level of the Floridan aquifer and the water table level of the surficial aquifer is referred to as "head difference." When the potentiometric surface of the Floridan aquifer is higher than the water table of the surficial aquifer, water can flow through a breached confining layer to the surface and appear as what is commonly called an "artesian well" or "spring." Where the potentiometric surface of the Floridan aquifer is lower than the water table of the surficial aquifer, surficial water can move through a leaky confining layer to the Floridan aquifer in a process known as "recharge." Water within the Floridan aquifer can move horizontally from an area of higher potentiometric surface towards an area of low potentiometric surface, but such movement is very slow and can take many, many years. Almost all of the Floridan aquifer recharge occurs through precipitation in areas where karst features are present and where the level of the surficial water table exceeds the potentiometric surface of the Floridan aquifer, thus permitting the precipitation to defuse into the Floridan system. The evidence establishes that the area of the wellfields at issue in this proceeding is generally characterized as one of a leaky confinement layer with substantial karst features. This finding is based on the credited testimony of the Respondents' expert witnesses, on the results of ground penetrating radar tests, measurements at nested well sites, and historical observation. Additional data related to aquifer withdrawal levels and nearby well measurements further support this finding. Ground penetrating radar tests are useful in measuring the existence of karst features below ground and under water bodies. To the extent that such tests have been performed in the area of the South Pasco, Cosme-Odessa, and Section 21 wellfields, the results indicate that karst features are prevalent and indicative of a leaky confining layer between the aquifers. "Nested" wells are paired wells, one into the surficial aquifer and the other into the Floridan, which are located within close proximity to each other. Concurrent measurements of water level fluctuations can indicate a connection between the aquifers. Such measurements within the vicinity of these wellfields indicate the existence of a poor confinement between the aquifers. WELLFIELD IMPACTS ON POTENTIOMETRIC SURFACE The wells at issue in this proceeding withdraw water directly from the Floridan aquifer. The water withdrawals result in a lowering of the potentiometric surface of the Floridan aquifer. The reduction of potentiometric surface by water withdrawal is referred to as "drawdown." The greatest drawdown occurs at the site of the well and becomes reduced with distance, resulting in a "cone-shaped" impact centered around the withdrawal area. The impact is referred to as a "cone of depression" in the water level. Drawdown impact can be influenced by the location of wells, the quantity and speed of withdrawal, precipitation, and the movement of water through the aquifer ("transmissivity") and between the aquifers ("leakage.") The "cone of depression" extends outward from the withdrawal point until the effects of the withdrawal are balanced by surficial recharge and inflow from the Floridan. Drawdown impacts are estimated by the use of groundwater flow models. The models generate contour lines which approximate the extent of drawdown related to specific water withdrawals. A drawdown contour "map" is generated by application of withdrawal projections to the model. The resulting map indicates the anticipated impact of water withdrawals. As mathematical estimates, drawdown models may not accurately measure impacts of water withdrawals on aquifers, however, they provide a useful tool to direct further observation and can be corroborated by appropriate actual measurements. The primary cause of the Floridan aquifer drawdown in the vicinity of the subject wellfields is the withdrawal of water by the Petitioners in accordance with water use permits issued by the District. This finding is based on the credited testimony of the Respondents' expert witnesses, on the results of aquifer performance tests and on review of monitoring well hydrographs. Additional support for this finding is provided by the groundwater flow model data analysis offered by the District. According to the District groundflow modeling, the drawdown at the South Pasco wellfield is from nine to twelve feet at the wellfield boundary, from four to seven feet at a distance of one mile from the boundary, and from three to five feet at a distance of two miles from the boundary. According to the District groundflow modeling, the drawdown at the Section 21 wellfield is from six to ten feet at the wellfield boundary, from four to seven feet at a distance of one mile from the boundary, and from two to five feet at a distance of two miles from the boundary. According to the District groundflow modeling, the drawdown at the Cosme-Odessa wellfield is from four to five feet at the wellfield boundary, from two to three feet at a distance of about a mile or so from the boundary, and from one to two feet at a distance of two and a half miles from the boundary. According to the District groundflow modeling, the drawdown at the NWHRWF is from three to four feet at the linear "wellfield" approximate boundary, from two to three feet at a distance of one mile from the boundary, and from one to two feet at a distance of two miles from the boundary. Floridan aquifer recharge in the vicinity of the subject wellfields occurs by surficial water flow through the porous confining layer. WELLFIELD IMPACTS ON SURFICIAL AQUIFER, LAKES AND WETLANDS The drawdown of the Floridan aquifer results in a lowering of the surficial water table as water leaks through the marginal confining layer and into the Floridan. The lowering of the surficial water table results in a lowering of area lakes and wetlands. The process by which water from the surficial aquifer leaks into the Floridan aquifer is known as "induced recharge." Induced recharge occurs where the head difference between the aquifers is reduced by Floridan aquifer withdrawals to the point at which surficial water will leak down through the confining layer and into the Floridan aquifer system. While other factors including reduced rainfall and increased evapotranspiration can result in lowered lake and wetland water levels, the evidence in this case establishes that the primary cause of lowered lake and wetlands water levels in the vicinity of the subject wellfields is the withdrawal of water at the wellfields resulting in induced recharge from the surficial aquifer to the Floridan aquifer. The evidence further establishes that the withdrawal of Floridan aquifer water in the area of the subject wellfields has resulted in dramatically increased fluctuations in the water levels of area lakes and wetlands. Normal "day-to-day" fluctuations in local lake water levels (called "amplitude") have been greatly increased by the groundwater withdrawals. Historical data, to the extent it exists, indicates that the current lake water in the area of the wellfields fluctuates within wider ranges, and at lower levels, than reflected by prepumping data. This finding is based upon the credited testimony of the Respondents' expert witnesses and on a review of historical hydrological data admitted into the record at hearing. Although the area has experienced an abnormal period of reduced precipitation, the impact of the wellfield withdrawals has exacerbated the water level fluctuations which could otherwise be attributed to a lack of rainfall. Surficial water table reductions related to induced recharge occur over an extended period of time. The quantity of water generally contained in the surficial aquifer tends to obscure the immediate impact of Floridan aquifer withdrawal, and accordingly, aquifer performance tests are generally poor measurements of the impact of Floridan aquifer withdrawals on the surficial aquifer, but review of historical data clearly indicates the impact. The gradual reduction in the surficial aquifer water table has resulted in a corresponding reduction of water levels in lakes and wetlands. Although each lake and wetland has different hydrogeologic features, and some are more impacted by groundwater withdrawal than are others, the evidence clearly establishes that the majority of lakes and wetlands in the area of the subject wellfields are hydrologically connected to the Floridan aquifer via the connection of the surficial aquifer to the Floridan, and that the lowering of the potentiometric surface of the Floridan aquifer has resulted in lowering of the surficial water table and of lake and wetland water levels. About nine percent of the land area within 100 square miles of the South Pasco, Cosme and Section 21 wellfields is covered with lakes. Analysis of data related to lake levels at Lake Rogers on the Cosme wellfield and Starvation Lake on the Section 21 wellfield show substantial average lake level declines clearly related to the groundwater withdrawal occurring in the wellfields. Lake Rogers has declined from an average level in 1930 of 45 feet (prior to the start of withdrawals) to a level of 30 feet in 1995. The evidence establishes that the lake level decline is the result of continued groundwater withdrawal. In fact, despite a cumulative rainfall deficit during the early 1960s, the water levels around the Cosme wellfield increased during a period of time during which water withdrawal quantities were being reduced. Starvation Lake has declined from an early 1960s average of 53 feet to 46 feet in about 1995. During a period when pumping from Section 21 was at greater quantities than now, Starvation Lake declined to about 42 feet. The evidence establishes that the lake level decline is the result of continued groundwater withdrawal. During the period from late 1991 to mid 1992, the level of Starvation Lake declined by about 37 inches. An analysis of the area precipitation/evapotranspiration indicates that almost 14.4 inches of the decline are attributable to induced recharge from the lake to the aquifer. As to the South Pasco wellfield, the depth to the water table was measured in the mid 70's (after the beginning of pumping from the wellfield) at approximately five feet at the wellfield center, and three feet near the wellfield boundaries. However, one mile north of the wellfield, the depth to the water table was approximately one-tenth of a foot. Camp Lake, located immediately east of the South Pasco wellfield, has shown a decline from a 1970 level of 63 feet to a 1995 level of 57 feet, a decline which corresponds to pumping activity and the related decline in the Floridan aquifer. Water is the driving force in wetlands ecosystems. The duration of water inundation in a wetland is known as the "hydroperiod." A decline in water table levels results in a reduction of wetland hydroperiod. Water storage, wildlife viability and nutrient cycling are water dependent wetland functions which can be negatively affected by a reduction in hydroperiod. Other impacts of reduced wetland hydroperiods include loss of hydric soils, wetland-dependent species declines, replacement of wetland species by upland species including "exotics," tree loss, and an increased incidence of fire. Wetland water inundation or saturation results in the formation of hydric soils by the accumulation of "peaty" organic material at a rate of about one millimeter annually. The lack of oxygen in an inundated or saturated state allows for the accumulation of material at a very slow rate of decomposition. The peaty deposits in the wetlands near the subject wellfields indicate that these wetlands have existed for at least a thousand years. Normal drought conditions will result in some loss of hydric soil. The reduction of the wetland hydroperiod related to groundwater withdrawals near the impacted wetlands provides an increased opportunity for decomposition of the hydric soils. Such decomposition, called "burning" or "oxidation" results in drying and destruction of the peat. As the peat soil dries, its volume is reduced; as the volume declines, the soil subsides. Substantial tree loss is a visible indication that serious soil subsidence has occurred as the soil which formerly supported the tree with nutrients and physical support declines. Wetland plants are those which thrive in the normal wetland environment. Variations in wetland hydroperiod can result in substantial alteration to the wetland community of species. As the wetland hydroperiod is reduced, the growth of "invasion" species such as Melaleuca and Brazilian pepper increased, another indicator of a stressed wetland system. Cypress wetlands are utilized by a number of endangered or threatened species, including the wood stork and the indigo snake, and by various wading birds. As the wetland hydroperiod is reduced, the ability of wetland dependent species to utilize the wetland is similarly reduced. Eventually, the loss of wetlands results in lost breeding grounds, nesting areas and roosts, and eventually the complete loss of the habitat for wetland-dependent species. An increased incidence of serious and destructive fire is another result of decreased hydroperiod and hydric soil alteration. Under normal conditions, fire in cypress wetlands rarely occurs. There may be small fires every few years and a "serious" fire every few hundred years. In normal conditions, fire will burn through vegetation, but inundated or saturated peat soils do not suffer severe fire damage. In an area of reduced hydroperiod, fires can burn through dry soils and declining vegetation, resulting in extensive damage and additional soil loss. About 21 percent of the land area within 100 square miles of the South Pasco, Cosme and Section 21 wellfields is covered with wetlands. Of the 100 square mile area, wetlands make up 35 percent of the land around the Section 21 field, about 15 percent of the land around the Cosme field and 55 percent of the land around the South Pasco field. About 1,500 acres of wetlands are within a one mile radius of the Section 21 wellfield. About 2,000 acres of wetlands are within a one mile radius of the Cosme wellfield. About 1,600 acres of wetlands are within a one mile radius of the South Pasco wellfield. In the area of the subject wellfields, wetlands have been and continued to be impacted by reduced water levels. The conditions existing in the wellfield-area wetlands include soil oxidation and subsidence, increased invasion by "exotic" species, increased incidence of fire, tree loss, and loss of habitat for wetland dependent species. The primary cause of reduced water levels in the wetlands is the lowering of the surficial aquifer caused by water withdrawals at the subject wellfields. This finding is based on the credited testimony of the District's expert witnesses including a review of historical data related to wetland impacts and the wellfield withdrawals, and comparison of wetlands in the vicinity of the wellfields to "control" wetlands away from the wellfield impact. The control wetlands exhibit longer hydroperiods and display fewer signs of ecological stress than do wetlands closer to the wellfields. The control wetlands display a greater abundance of wetland-dependent species than do the wellfield-area wetlands. Notwithstanding the adverse impacts of the permitted water withdrawal, the hydrogeologic systems in the area of the wellfields have reached "dynamic equilibrium." A major water withdrawal from the Floridan aquifer results, after a period of several years, in a shifting of hydrological systems to accommodate the lowered levels. It can take as long as ten years for the changes and restabilization process to occur. Once the aquifer systems have stabilized, the systems have reached a "dynamic equilibrium." The hydrologic systems in the area of the subject wellfields have reached dynamic equilibrium. The evidence establishes that the major adverse impacts which occurred in the vicinity of the subject wellfields began shortly after the inception of water withdrawals from the wellfields. Although clearly adverse environmental impacts have occurred and are the result of water withdrawal, the water systems in the area of the wellfields have "reset" and are now essentially stable at the lowered levels. The Petitioners suggest that the adverse environmental impacts visible in the ecosystems on and near the wellfields can be attributed to natural ecosystem succession. The assertion is not supported by credible evidence. The greater weight of the evidence establishes that the major adverse environmental impacts are related to the withdrawal by the permittees of substantial quantities of water from the Floridan aquifer. The Petitioners assert that recent levels of low rainfall are the primary cause for the lowered lake levels and reduced wetland hydroperiods. The evidence fails to support the assertion. There is insufficient evidence to establish that recent low rainfall levels are indicative of a long term situation. The greater weight of the evidence indicates that recent low rainfall events are likely part of a cyclical precipitate system which historically experiences periods of increased and decreased rainfall. The major adverse environmental impacts to the lakes and wetlands are the result of water withdrawal. The low rainfall levels have exacerbated the situation, resulting in a lack of surficial water inflow into lakes and wetlands sufficient to replace that water which is continuously leaking from the surficial aquifer into the Floridan aquifer, as well as that which is lost from the surface via evapotranspiration. Although environmental monitoring efforts by the Petitioner are suggested to indicate that the deleterious effects of the reduced water levels are being remedied by recent increased rainfall levels, the evidence is insufficient to establish that the impacts of reduced hydroperiods related to groundwater withdrawals will be remedied by a return to "normal" rainfall levels. Recent increased rainfall has contributed to an increase in water levels. The typical changes which would be expected to accompany increased precipitation, such as signs of water in formerly dry littoral zones, are visible in a some areas. However, overall lake levels remain lowered, exposed lake beds are visible, and upland vegetation continues to grow on what was formerly lake bottom. The former shorelines are visible and clearly delineated by vegetation lines. The evidence fails to establish that the recent rainfall increase will correct the adverse impacts caused by the withdrawal of water from the subject wellfields. While the greater Tampa Bay area has recently seen cyclical low levels of precipitation, the predominant cause of the lowered surficial water table in the vicinity of the subject wellfields is the groundwater withdrawals from the wellfields. A return to "normal" rainfall levels will not address the systemic alterations which have occurred in the wellfield-area wetlands. If it is assumed that a lack of rainfall is the cause of the decline in the surficial water table, the conditions of the wellfields should be generally similar regardless of whether the wetlands are on/near the wellfields, or whether they are located at some distance from the fields. The evidence establishes that the wetlands near the area of the wellfields display signs of a gradual and continuing decline. Wetlands outside the wellfield impact do not show the same level of decline. It is reasonable to assume that periods of increased rainfall would result in increased water levels in area lakes, however, a review of data indicates that the lakes near the wetlands do not respond to rainfall in a normal manner. Despite two years of average to above average rainfall, the lakes at the Section 21 and Cosme wellfields continued to be substantially below normal. A comparison of potentiometric surfaces at monitoring wells on and off the wellfield sites further establishes that the lowering of the water table is not a precipitation-induced event. Monitoring wells on the wellfield sites have shown substantially increased reductions in potentiometric surface as compared to monitoring wells located in areas not impacted by the withdrawals. The Petitioners assert that area drainage projects have caused a reduction of water flow into the wellfield lakes and wetlands and that such flow reduction is the cause of the visible impacts to such water features. The evidence fails to establish that there have been regional or local surficial flow changes sufficient to result in the reduction of water in nearby lakes and wetlands or in the decline in the surficial aquifer. Although drainage projects near some wellfields could potentially impact surface water movement, the evidence that such drainage projects are responsible for the lowering of the surficial water table in the vicinity of the wellfields is not persuasive. The Petitioners assert that land development in the area of the wellfields has resulted in reduced water flow into the wellfield lakes and wetlands and that such flow reduction is the cause of the visible impacts to such water features. The evidence fails to support the assertion. The type of analysis required to establish the impacts of drainage on surficial water systems has not been performed. Current surface water management system permitting rules in effect since 1984 are designed to reduce the impacts of surface drainage on surrounding waterflow systems. Systems constructed in compliance with permitting rules retain water on the development site and can provide additional groundwater recharge. The evidence is insufficient to establish that significant development near the Section 21 wellfield is the cause of the lowered water levels on or near the wellfield There is relatively little urban development near the Cosme and South Pasco wellfields which could potentially impact water flow. The evidence fails to establish that the existing development hydrologically impacts the wellfield. The evidence fails to establish any relevant impacts caused by highway construction on the area hydrology. The Petitioners also assert that, rather than the South Pasco wellfield pumping, it is the land management practices by property owners to the east of the South Pasco field which are responsible for degraded conditions. Although land management practices, specifically burning, may have damaged wetlands, dry conditions related to pumping-related surficial aquifer declines likely resulted in more severe burn damage than would have otherwise occurred. "BASELINE" The District has adopted by rule permitting criteria which are considered in the review of an application for water use permit. The permitting criteria are further addressed in the District "Basis of Review." In part, the review of a water use permit application seeks to determine the anticipated impact of the proposed water withdrawal on wetlands, water resources and other natural systems by utilization of the permitting criteria and the Basis of Review (BOR). Such analysis requires establishment of a "baseline" against which anticipated impacts may be predicted. The baseline provides a point against which future impacts to a resource by a permitted water withdrawal can be measured. A baseline also provides a standard by which the success of mitigation efforts can be measured. The permitting history for the subject wellfields, including review of staff analyses, indicates that the adverse environmental impacts related to the water withdrawals were known to the District during earlier permit application considerations. The evidence establishes that in prior permit decisions, the District determined that the adverse environmental impacts were anticipated, and exempted the permittees from certain environmental standards which would likely have reduced the adverse impacts. The District Governing Board's decision to exempt permittees from meeting certain criteria related to adverse environmental impacts where such exemption was in the "public interest" was a discretionary act by the Board. The evidence fails to establish that the adverse environmental impacts caused by the actual withdrawal of water at current quantities from the subject wellfields have exceeded the adverse impacts which were previously deemed acceptable by the District. Although the District's rules have been changed to eliminate the granting of exemptions from permitting criteria, the evidence fails to establish that the District was ever required to exempt an applicant from meeting the criteria. The four wellfields at issue in this proceeding have operated in compliance with the permits issued by the District. None of the wellfields have been cited for violations of permit conditions. There is no evidence that any Notice of Violation has been issued regarding any operational aspect of these wellfields. There is no evidence that the District has initiated any permit condition enforcement action related to these wellfields. The District has been authorized under the previous permits to require mitigation of adverse environmental impacts related to the permitted withdrawals. There is no credible evidence that the District has taken formal action to require mitigation of adverse environmental impacts related to the subject groundwater withdrawals. The environmental conditions caused by withdrawal of water at the subject wellfields are those which were previously deemed acceptable and consistent with the public interest by the District. For purposes of this Recommended Order, baseline conditions are those conditions, including previously permitted adverse impacts, which existed at the time of the filing of the renewal applications. EXISTING PERMITTED ADVERSE IMPACTS The evidence establishes that there have been adverse environmental impacts in the area of the South Pasco wellfield caused by the withdrawal of groundwater. The evidence includes the credited testimony of expert witnesses, review of historic photographs, comparison of land use and cover classifications during the period of water withdrawals, and review of monitoring site data. The current area impacts related to the water withdrawal at South Pasco include a reduction in wetland hydroperiod, significant biological change, alteration of normal wet-season water levels, extensive oxidation and subsidence of soils, substantial cypress tree decline, increased damage by abnormal fire, significant declines in wetland species composition, and impairment and loss of habitat for wetland dependent species, including threatened and endangered creatures. There has been an alteration in community zonation, community types and plant species composition. Lake impacts related to South Pasco water withdrawal include adverse impacts to Camp Lake, Mary Lou Lake, Lake Ruth, and Long Sun Lake. The water level at Camp Lake has shown substantial impact since the initiation of pumping. Other lakes have been impacted to the extent that aesthetic and recreational values are impaired. Animal populations have been altered, and normal ranges of water level fluctuation have been impacted. The evidence establishes that there have been adverse environmental impacts in the area of the Section 21 wellfield caused by the withdrawal of groundwater. The evidence includes the credited testimony of expert witnesses, review of historic photographs, comparison of land use and cover classifications during the period of water withdrawals, and review of monitoring site data. The current area impacts related to the water withdrawal at Section 21 include a reduction in wetland hydroperiod, alteration of normal wet-season water levels, extensive oxidation and subsidence of soils, substantial cypress tree decline, significant declines in wetland species composition, and impairment and loss of habitat for wetland dependent species, including threatened and endangered creatures. There has been an alteration in community zonation, community types and plant species composition. Lake impacts related to Section 21 water withdrawal extend at least one mile from the wellfield and include adverse impacts to Starvation Lake, Lake Jackson, Lake Simmons, Lake Oakley and Lake Crum. Shorelines are exposed, upland and exotic species have invaded formerly wet areas, animal populations have been altered, and normal ranges of water level fluctuation have been impacted. The evidence establishes that there have been adverse environmental impacts in the area of the Cosme-Odessa wellfield caused by the withdrawal of groundwater. The evidence includes the credited testimony of expert witnesses, review of historic photographs, comparison of land use and cover classifications during the period of water withdrawals, and review of monitoring site data. The current area impacts related to the water withdrawal at Cosme-Odessa include a reduction in wetland hydroperiod, alteration of normal wet-season water levels, extensive oxidation and subsidence of soils, substantial cypress tree decline, significant declines in wetland species composition, and impairment and loss of habitat for wetland dependent species, including threatened and endangered creatures. There has been an alteration in community zonation, community types and plant species composition. Lake impacts related to Cosme-Odessa water withdrawal extend at least one mile from the wellfield and include adverse impacts to Horse Lake, Church Lake, Lake Rogers, Lake Raleigh, Lake Amelia and Calm Lake. Shorelines are exposed, upland and exotic species have invaded formerly wet areas, animal populations have been altered, and normal ranges of water level fluctuation have been impacted. As compared to the other three wellfields at issue in this proceeding, the impacts related to the NWHRWF are minimal. Given the "linear" nature of the NWHRWF, wellfield-related adverse environmental are not localized but spread over a larger area than is the case with the other production wellfields. Accordingly the signs of environmental degradation which are visible at the other three wellfields are not visible in the vicinity of the NWHRWF. Two wetlands in the vicinity of the NWHRWF currently exhibit hydrologic impacts and upland species invasion, one near the "NW-1" well and another near the intersection of Gunn Highway and Turner Road. The evidence fails to establish that the adverse impacts at these two wetlands are related to the production of water at the NWHRWF. PERMITTING CRITERIA AND ACTUAL CURRENT WITHDRAWALS The evidence establishes that for the quantity of water currently being withdrawn from the wellfields, the applicants meet the relevant permitting criteria. To obtain the water use permits sought in this proceeding, the Petitioners must establish that the proposed use of water is a reasonable-beneficial use, that the proposed use will not interfere with any presently existing legal use of water, and that the proposed use is consistent with the public interest. As to the quantity of water currently being withdrawn from the wellfields, the evidence establishes that the proposed use of water is a reasonable-beneficial use, the proposed use will not interfere with any presently existing legal use of water, and the proposed use is consistent with the public interest. The evidence establishes that there will no new adverse environmental impacts caused by the continuation of pumping from the subject wellfields at quantities currently being withdrawn. The continuation of water pumping at current actual levels of withdrawal will continue the ecological decline already in progress, but will not result in new kinds of adverse environmental impacts. Over the long term, areas of reduced hydroperiod will continue to experience invasion by upland species and soil oxidation. The biological characteristics of the impacted areas have been altered. Wetland obligate vegetation will continue to decline. Populations of lake and wetland dependent creatures will be reduced as the water levels remain lowered by the impact of the pumping. Fires will continue to pose an increased threat to the already damaged wetlands. Despite the existing adverse impacts, there is no credible evidence that impacted areas would return to prepumping conditions even if pumping were halted from the subject wellfields. The actual withdrawal of water at levels not greater than those currently being pumped is a reasonable and beneficial use of the resource. The provision of potable water to the customers of the water utility systems which receive water from the authority is a reasonable and beneficial use of the resource. There is no evidence that the existing potable water requirements of the end users may be met by any other currently available water resource. The actual withdrawal of water at levels not greater than those currently being pumped will not interfere with other existing legal uses. The evidence establishes that where existing water uses predate the District's water use permitting program, such existing uses are not required to demonstrate non-interference with other existing legal uses unless the applicant proposes to withdraw additional quantities or create an impact greater than was previously permitted. In this case, the Petitioners seek to have the existing permits renewed at the quantities set forth in the existing permits. The proposed use is consistent with the public interest. The reliable provision of high quality water to the citizens of Florida is necessary to meet public health and safety requirements and is clearly consistent with the public interest. The Authority supplies water to a total population estimated at 1.8 million residents. Although the wellfields at issue in this proceeding supply only about 35 percent of the permitted water capacity distributed by the Authority, the evidence establishes that it is unlikely the Authority could supply the quantities currently required without utilization of these wellfields. Though the Authority operates an interconnected water supply system, the existing configuration of the supply lines does not allow for unrestricted provision of water from any wellfield to all users. The Section 21 wellfield supplies water to the residents of northwest Hillsborough County. Were the Section 21 wellfields to be unavailable, the Authority could not immediately route water to the northwest Hillsborough users from other fields. Likewise, the other three wellfields supply water to St. Petersburg, and the Authority would be unable to meet water requirements were the wellfields closed or pumping was substantially restricted. The District asserts that the lack of proper permits does not necessarily lead to the conclusion that these wellfields would be closed, and that water could be legally pumped via a series of emergency orders. There is no evidence that the District has made any legally binding commitment to allow for water withdrawals outside the appropriate permitting process. There is no evidence that the denial of permit renewal applications is an appropriate method for remedying adverse environmental impacts which are the result of previous permitting decisions and which were identified prior to issuance of the existing permits. Although the Petitioners estimate the cost of developing a water resource to replace the permitted capacity lost if these applications are denied to be about $180 million dollars, the cost estimate has insufficient supporting documentation to indicate that it is accurate. There is no evidence that the permittees have initiated any credible effort to replace the total quantity of water being withdrawn from the subject wellfields with new water sources of similar quality. The evidence establishes that at current actual quantities of water withdrawal, the Petitioners comply with the criteria requirements for issuance of the permits. Reasonable assurances have been provided that the withdrawal of water at the quantities currently being pumped is necessary to fulfill a certain reasonable demand for water. The actual quantity being withdrawn at the subject wellfields is necessary to meet current reasonable demand. The evidence further establishes that the actual quantity being withdrawn at the subject wellfields is capable of continuing to meet potable water demand during the permit renewal period. As for projected future demand, St. Petersburg estimates that it will need 43 mgd of water by 2007. The maximum annual average daily withdrawal from these wellfields is as much as 40.9 mgd. St. Petersburg receives an additional 6.2 mgd from the Authority as part of a water agreement "entitlement." Absent any additional available resources, the total maximum available quantity of 47.1 mgd would be sufficient to meet the water requirements of St. Petersburg. However, the evidence as to future demand in St. Petersburg fails to establish that St. Petersburg will require actual total withdrawals at the maximum levels currently permitted. Between 1983 and 1994, St. Petersburg's potable water use averaged about 39 mgd. From 1991 to 1994, the potable water use was about 37 mgd, indicating that potable water use is declining. At the hearing, St. Petersburg produced data which indicated anticipated total demand could be as low as 40.8 mgd, based on current usage patterns. The evidence establishes that St. Petersburg's water requirements can be met without increasing the actual quantities of water currently being withdrawn from the subject wellfields. Expanded and more appropriate utilization of the reclaimed water which is already available, and additional conservation measures and use restrictions identified in the pending Water Resource Development Plan, will provide sufficient water without increased withdrawals from the subject wellfields. Given the reduction in water use though increased utilization of reclaimed water and additional conservation measures, the evidence establishes that the projected water needs can be met without increasing the quantities currently being withdrawn from the subject wellfields. Reasonable assurances have been provided that the continued withdrawal of water from the subject wellfields at the quantities currently being pumped will cause no changes which adversely impact the water resources, including both surface and ground waters, beyond those previously permitted by the District. The continued withdrawal of water from the subject wellfields at the quantities currently being pumped will cause no changes which adversely impact water resources, beyond those previously known to and permitted by the District. There is no credible evidence that any new adverse environmental impacts will result from withdrawal at current actual quantities. Reasonable assurances have been provided that the continued withdrawal of water from the subject wellfields at the quantities currently being pumped will not cause adverse environmental impacts to wetlands, lakes, streams, estuaries, fish and wildlife, or other natural resources waters, beyond those previously permitted. Adverse environmental impacts have resulted from the permitted withdrawal of groundwater as identified elsewhere in this order. The District has had the ability to require mitigation through conditions attached to prior permits. The District has the authority to continue to attach mitigation conditions to the permits issuing from this proceeding. There is no evidence that adverse environmental impacts caused by groundwater withdrawal can not be mitigated, however, it is difficult to determine, absent any direction from the District, the type of mitigation which would meet the District's approval. Reasonable assurances have been provided that the continued withdrawal of water from the subject wellfields at the quantities currently being pumped will not cause water levels or rates of flow to deviate from the ranges set forth in Chapter 40D-8. To the extent that such ranges are established, the evidence establishes that water withdrawals at current actual levels will not result in deviation from established ranges. Reasonable assurances have been provided that the continued withdrawal of water from the subject wellfields at the quantities currently being pumped will utilize the lowest quality water that the Applicant has the ability to use. St. Petersburg initiated a water reuse program in 1977, and is committed to expansion of the reuse system. The reuse program replaces potable water with reclaimed water in irrigation and some industrial applications. The St. Petersburg reuse program is nationally recognized. St. Petersburg currently has excess capacity in its reclaimed water system and has begun to increase the rate of expansion by reducing connection fees and taking other steps to allow easier neighborhood access to the reuse system. Reasonable assurances have been provided that the continued withdrawal of water from the subject wellfields at the quantities currently being pumped will not adversely impact offsite land uses existing at the time of the application, beyond those previously impacted by permitted withdrawals. There will be no additional adverse impact to offsite land uses existing at the time of the application as a result of the continued withdrawal of water at current actual quantities. Reasonable assurances have been provided that the continued withdrawal of water from the subject wellfields at the quantities currently being pumped will not adversely impact any existing legal withdrawal beyond those previously impacted by permitted withdrawals. Reasonable assurances have been provided that the continued withdrawal of water from the subject wellfields at the quantities currently being pumped will utilize local resources to the greatest extent practicable. The evidence establishes that the potable water being withdrawn from the subject wellfields constitutes utilization of local resources to the greatest extent practicable. There is no credible evidence that a sufficient potable water supply is located more proximately to the St. Petersburg water users. The District asserts that the alleged misuse of excess reclaimed water demonstrates a failure to utilize local resources to the greatest extent practicable. The evidence does not support the assertion. Reasonable assurances have been provided that the continued withdrawal of water from the subject wellfields at the quantities currently being pumped will incorporate water conservation measures. The District has set a per capita water use goal for the Northern Tampa Bay region of 140 gallons per day (gpd) by the beginning of 1997 and 130 gpd by the start of 2001. St. Petersburg's current water use rate is 122 gpd, substantially below the District's level. The evidence establishes that substantial efforts are being made by the Petitioners to reduce water use where such is economically feasible. St. Petersburg enforces lawn watering restrictions. New construction standards and a program aimed at replacement of existing residential bath fixtures encourage use of water-saving fixtures. St. Petersburg utilizes a water use rate structure which encourages conservation. Specific water conservation goals have been established. The District asserts that the Petitioners have not sufficiently demonstrated a commitment to conserve water to the satisfaction of the District. The fact that current water use in St. Petersburg is less than in other local areas, and in fact is below the District's mandated rate for 2001, suggests otherwise. While it is almost always possible to suggest that "more should be done," the evidence establishes that the Petitioners are making a good faith effort to conserve water resources. It is reasonable to expect that the Petitioners will continue to explore methods of reducing potable water use. Reasonable assurances have been provided that the continued withdrawal of water from the subject wellfields at the quantities currently being pumped will not cause water to go to waste. The District criticizes St. Petersburg's reluctance to meter the use of reclaimed water and suggests that the lack of metering results in excess use of the available reclaimed water, which could otherwise (assuming expansion of the system) be available to other users. St. Petersburg states that metering would discourage use and that one of the goals of the reuse program is to dispose of wastewater. Unused reclaimed water is disposed of by deep-well injection. St. Petersburg asserts that the reuse program has the capacity to serve about 11,750 customers. At the end of 1994, there were about 7,600 customers. The evidence establishes that there is excessive use of reclaimed water by some consumers. Moderating excessive reclaimed water use would permit the system capacity to serve a total of about 17,000 customers. Increasing reclaimed water service to 17,000 customers could reduce the need for potable water by five mgd. It is logical to assume that as the potable water supply becomes less available and more costly, reclaimed water will become more valuable and more important in meeting the water needs of St. Petersburg It is likely that limitations on water withdrawals from the subject wellfields will serve to increase the value and utilization of reclaimed water. The District asserts that St. Petersburg's reuse system encourages overuse of reclaimed water and discourages citizens from connecting to the reuse system. Expansion of the reuse system requires installation of distribution lines. While there is no credible evidence that St. Petersburg's expansion program has been intentionally delayed, high connection charges and threshold for neighborhood participation have delayed system expansion. The evidence establishes that there is additional demand for reclaimed water by users in St. Petersburg. Reuse distribution lines are installed in neighborhoods where water users express interest in obtaining the reclaimed water. During a recent "sale", citizens were encouraged to connect to the reuse system through subsidized connections. St. Petersburg reduced from 50 percent to 30 percent, the number of homeowners who must agree to connect to the system prior to distribution line installation. Reduced-interest and extended payment loans were made available to homeowners to pay for the cost of connection. More than 2,000 customers signed up during the "sale." It will take about a year and a half for the city to meet the expansion demand established through the sale. The District asserts that metering of the reuse system will reduce waste of the reclaimed water. Although St. Petersburg suggests that metering will discourage use of the reclaimed water system, St. Petersburg is currently installing water meters to test the impact created by metered use. At this time, the evidence fails to establish that metering will reduce waste, though it is reasonable to assume that metering, and a conservation oriented rate structure, will reduce excess use. PERMITTING CRITERIA AND MAXIMUM QUANTITIES The existing permits allow for water withdrawals at quantities higher than those currently being withdrawn. The combined actual average daily withdrawals at the four wellfields total about 40 mgd. The maximum permitted capacity at the four subject wellfields is about 49 mgd. The evidence is insufficient to establish that at the 49 mpg maximum withdrawal levels set forth in the current permits, the Petitioners comply with the criteria requirements for issuance of the permits. The Petitioners assert that adverse environmental impacts will not occur even if pumping is at full permitted capacity. The evidence fails to support the assertion. Testimony that pumping from the subject wellfields could be increased by as much as 25-30 percent without an increase in the severity and extent of adverse environmental impacts is without credible foundation and is rejected. The issue of "rotational capacity" is offered by the Petitioners as rationale for issuance of permits which permit pumping beyond the quantities currently being withdrawn. Interconnected wellfields offer the ability to rotate withdrawals between the connections in order to allow time for repairs to a well, and to allow some facilities to "rest" and recover from environmental stress. In order to provide this ability, pumping from one of the interconnected wellfields is increased to reduce pumping from the stressed wellfield. The "rotational capacity" of the system is the quantity of water above that which is currently being withdrawn and which allows for pumping to be increased at the less stressed wellfield. The evidence fails to establish that "rotational capacity" can not be achieved without permitting withdrawals from the wellfields to increase above those quantities currently being withdrawn. The evidence fails to establish that increased water withdrawals, up to the maximum quantities set forth in the existing permits, will not interfere with other existing legal uses. The evidence fails to establish that pumping from the subject wellfields at maximum permitted quantities will not result in additional adverse environmental impacts. The evidence fails to establish that the withdrawal of water from the subject wellfields in excess of the quantities currently being pumped will not cause quantity or quality changes which adversely impact water resources, including both surface and ground waters. The evidence fails to establish that the withdrawal of water from the subject wellfields in excess of the quantities currently being pumped will not cause adverse environmental impacts to wetlands, lakes, streams, estuaries, fish and wildlife, or other natural resources waters. The evidence fails to establish that the withdrawal of water from the subject wellfields in excess of the quantities currently being pumped will not cause water levels or rates of flow to deviate from the ranges set forth in Chapter 40D-8. MITIGATION The evidence fails to establish that the Petitioners have proposed any appropriate mitigation which would address the existing environmental impacts of water pumping from the subject wellfields. Further, no acceptable mitigation plans have been proposed to address the adverse impacts which would accompany increased withdrawals from the four wellfields. The Authority has proposed an Environmental Management Plan (EMP) which provides a method of monitoring environmental conditions to determine whether mitigation of impacts would remedy adverse impacts. Although the EMP could provide reliable data in addition to that already available, the EMP, even if implemented, does not constitute mitigation of adverse impacts. One form of possible mitigation suggested by the Petitioners is the concept of "augmenting" lakes and wetlands by the addition of water taken from other lakes or wells to lakes with lowered water levels, or by the addition of excess reclaimed water to wetlands. The augmentation proposal is specifically addressed in St. Petersburg's "4-D's" report. The evidence fails to establish that the 4-D's report presents a reasonable mitigation proposal. Augmentation presents a number of biological concerns related to the addition of one type of water to another. Such issues include alteration of water balance, introduction of different non-native microscopic organisms into the receiving water, nutrient alteration, and coliform bacteria concerns. The evidence fails to establish that lake and wetland augmentation is an adequate or appropriate means of mitigating adverse impacts related to groundwater withdrawal. The evidence that the District has permitted lake augmentation in other situations fails to establish that such mitigation is an adequate method of addressing adverse impacts related to groundwater withdrawal. The evidence establishes that the Authority has implemented a "Good Neighbor Policy" under which the Authority repairs or replaces local private wells which experience problems possibly related to the water withdrawals at the NWHRWF. There is evidence that the Authority makes such repairs without determining the actual cause of the problem in an attempt to address local citizen complaints. The Authority has implemented the policy voluntarily. In two cases, the District received complaints from citizens unsatisfied by the Authority's response. The Authority provided additional assistance and eventually remedied the problems. Although the "Good Neighbor Policy" provides an adequate program to address the concerns of private individuals in the area of the NWHRWF, the evidence fails to establish that the general policy is adequate mitigation of the adverse environmental impacts caused by the wellfield water withdrawal. A monitoring program being performed on behalf of the Petitioners could provide an acceptable framework for monitoring and mitigating future adverse environmental impacts. Beginning in 1983, an environmental monitoring program was established by Water and Air Research, Inc., (WAR) for the NWHRWF. The water use permit for the NWHRWF requires implementation of a monitoring program. The NWHRWF monitoring program includes 67 monitoring stations and additional transect areas, and covers an area of approximately 120 square miles including areas near the Section 21 and Cosme-Odessa wellfields. The data collected from the monitoring program was published in annual reports which have been submitted by West Coast to the District. Beginning in 1991, WAR established an environmental monitoring program at the South Pasco wellfield on behalf of the Authority and St. Petersburg. The South Pasco wellfield permit does not require implementation of an environmental monitoring program. The WAR/South Pasco monitoring program includes nine monitoring stations. The data collected from the WAR/South Pasco monitoring program was published in three annual reports. In addition to the WAR monitoring program, CH2M Hill was retained in anticipation of these permit renewal applications to assess the condition of the South Pasco, Section 21, and Cosme-Odessa wellfields. CH2M Hill designed a three phase assessment program which includes a comparative review of land uses around the wellfields, a comparative review of ecological function both on- site and off-site of the fields with available historical data, and a detailed quantitative survey of current ecological conditions at the wellfields and at identified control sites. Although the WAR monitoring programs or the CH2M Hill assessment project are not without flaws, they provide the ability to quantify any future adverse environmental impacts caused by the continued withdrawal of water from the subject wellfields against a more detailed "baseline" measurement than that which has previously been available. The WAR/CH2M Hill programs also appear to provide the ability to gather more site- specific data than any program currently being utilized by the District. The WAR/CH2M Hill projects are not accepted for the purposes of determining historic impacts which have occurred since the inception of water withdrawals from the subject wellfields. The analysis of land use changes in the areas of the four wellfields, suggesting that the adverse environmental conditions were primarily related to factors other than pumping, was not persuasive. Evidence as to whether the selection of monitoring sites for the WAR/CH2M Hill projects appropriately represent the current state of the lakes and wetlands in the area of the wellfields was unpersuasive. Further, the WAR/CH2M Hill analysis of the current data provided by the witnesses involved in the project was not credible as to conclusions that the adverse impacts were being reversed by the recent cyclical return to more rainfall. It is not unusual to expect that where wetlands still exist, increased rainfall would show increased abundance of wetland dependent species. Increased rainfall results in temporarily increased lake levels and visible upland vegetation die-off will occur when the water level reaches the vegetation. The data is insufficient at this time to establish that there is any general "recovery" occurring in the ecosystems impacted by the withdrawal of water from the Floridan aquifer. The Petitioners assert that the WAR/CH2M Hill projects are more intensive than the monitoring projects utilized by the District. The evidence establishes only that over an extended period of time, the WAR/CH2M Hill projects are capable of providing quantities of detailed data related to the condition of the wellfields. The evidence fails to establish that the data currently generated by the WAR/CH2M Hill projects provides a basis for reliable long term analysis. THE NWHRWF DEFAULT PERMIT ISSUE As stated previously, the Authority asserts entitlement to an unrestricted default permit for the NWHRWF. The evidence establishes that the Authority is entitled to a default permit, but does not support issuance of an unrestricted water use permit. During the permit renewal process, the NWHRWF application was combined with the Manors at Crystal Lake wellfield permit which had been held by Hillsborough County. Hillsborough County turned operational responsibility over the wellfield and over the renewal permitting process to the Authority. Notice of the District's completeness determination was sent not to Hillsborough but to the Authority, which was identified on the permit as the applicant. Prior to the District's first decision deadline, the District sought by letter to Hillsborough and copy to the Authority, an extension of the deadline to December 31, 1994. By separate letters, both Hillsborough and the Authority consented to the extension. The District was apparently unable to act by the deadline and sought a second extension to March 1, 1995, but the District's request was sent only to a representative of Hillsborough County. No copy of the request was provided to the Authority. At the time the District sought the second extension from Hillsborough County, the District had been notified that the Authority had assumed responsibility for the NWHRWF/Crystal Lake renewal application. The District claims that the request to Hillsborough County, rather than to the Authority was proper because Hillsborough had been the permittee on the expiring permit. However, the District had notified only the Authority that the combined applications had been deemed complete. Apparently unaware that Hillsborough had withdrawn from the permit renewal application process, the Hillsborough representative consented to the second extension, but did so without consultation with the Authority. The Authority did not consent to the second extension. At the time the District sought the second extension, Hillsborough County had no responsibility for or authority regarding the combined NWHRWF/Crystal Lake renewal application. The District issued it notice of proposed action on the NWHRWF on February 7, 1995. The Authority asserts that it is entitled to an award of a default permit for the NWHRWF based upon the failure of the District to grant or deny the permit by the December 31, 1994 deadline extension to which the Authority had consented. The evidence fails to establish that the Authority is entitled to receive an unconditioned permit based on the District's failure to meet the December 31 deadline. The evidence does establish, based upon the failure of the District to meet the December 31 deadline or obtain an extension from the Authority as the applicant for the permit, that the Authority should receive a ten year permit for operation of the NWHRWF subject to the conditions set forth herein.
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 water use permits for the subject wellfields with the following conditions: The permits should be valid for a period of ten years from the date of issuance. The maximum permitted quantities for each of the four permits should be reduced to not more than the average annual daily quantity currently being withdrawn at each wellfield. In order to provide rotational capacity, the permits should be structured to provide, upon approval of the District, for water withdrawal in excess of the permitted quantities at any of the four wellfields, so long as the increase in withdrawal from one wellfield is balanced by decreased withdrawal at another wellfield. The renewal permits should provide for no increased water withdrawals beyond the actual quantities currently being pumped from these wellfields. Environmental monitoring should continued and be expanded to include areas not currently being monitored. The monitoring program should be jointly undertaken and funded by the permittees and the District. The District shall determine the number and placement of monitoring stations and the frequency with which data shall be collected and reported. The Authority's "good neighbor" policy at the NWHRWF should be made a condition to the NWHRWF permit. The City of St. Petersburg's water reuse program should be expanded to provide additional service where such expansion is feasible. St. Petersburg shall implement continuing measures to encourage enrollment of new customers, including permanent reductions in connection fees and neighborhood participation thresholds, as has been done during the recent campaign to increase connections. St. Petersburg shall also implement measures to reduce the excessive use of reclaimed water by current customers. The District shall establish time-specific deadlines by which St. Petersburg's compliance with this condition can be measured. The permits should include all standard conditions which are generally applicable to the subject water use permits. RECOMMENDED this 29th day of May, 1997, in Tallahassee, Florida. WILLIAM F.

Findings Of Fact During approximately 1961, the Board of County Commissioners of Orange County adopted the Orange County Conservation and Water Control Act. This act included a comprehensive drainage plan. Orange County is divided into several natural drainage basins. The Petitioner is presently actively seeking to implement the comprehensive drainage plan in what is known as the Upper Howell Branch drainage basin. The proposed Lateral H-15 forms a part of the drainage plan in the Upper Howell Branch drainage basin. The proposed Lateral H-l5 would begin at the outfall of Park Lake, and would extend approximately 1900 feet to Lake Maitland. Lateral H-l5 would allow the controlled lowering of Park Lake, with excess water flowing into Lake Maitland. Lateral H-15 as proposed would be a structure with a concrete paved bottom. It would be 18 feet wide, and would have vertical side walls constructed of aluminum siding. A weir would be constructed at the Park Lake outfall, and a new crossover would be constructed at the point where Highway 17-92 crosses over the project. The depth of the structure would be 5 feet. At peak flows water would flow at four foot depths leaving a one foot free area. The structure has been designed to allow passage of peak flows of water using as little land area as possible. Vertical side walls have been proposed in order to limit the amount of property which the Petitioner would need to obtain in order to construct the project. The Petitioner's comprehensive drainage plan is designed to ultimately prevent flooding which would result from a "25 year storm". The term "25 year storm" means that there is a 4 percent chance that such a storm would occur in any given year. The Petitioner's comprehensive plan for the Upper Howell Branch basin is depicted in an aerial photograph which was received into evidence as Petitioner's Exhibit 1. Generally, waters within the basin will flow from Lake Killarney through Lateral H-22, which is nearly completed, and from Lake Bell through the Lake Bell Lateral, which has been completed, into Park Lake. The Lake Bell Lateral and Lateral H-22 permit the controlled lowering of the water in Lake Bell and Lake Killarney into Park Lake. Lateral H-15 would permit the controlled lowering of the waters of Park Lake into Lake Maitland. Waters from Lake Maitland would then flow out of the drainage basin through Howell Creek which is now extremely swampy. Petitioner proposes ultimately to clear Howell Creek so that it can accept peak water loads from Lake Maitland. The proposed Lateral H-15 would follow the channel presently followed by a naturally occurring creek bed known as the Maitland Branch. Maitland Branch is a dried up waterway during dry weather periods. When waters in Park Lake rise during rainy seasons, overflow goes through the Maitland Branch into Lake Maitland. In addition storm runoff from areas surrounding the Maitland Branch drain into Maitland Branch and then into Lake Maitland. At its most Westward point, adjacent to Park Lake, the Maitland Brunch is approximately 40- 50 feet wide. A railroad crosses the branch near to the Park Lake outfall and the pipe and culvert under the railroad control the water level in the branch. The branch then extends under Highway 17-92, and into Lake Maitland. From the railroad, into Lake Maitland, Maitland Branch is confined to a narrow channel. The Maitland Branch is not a navigable water body. Lake Maitland is a navigable water body. Petitioner's proposed dredging activities would extend approximately 55 yards into Lake Maitland in order to permit the free flow of waters through the proposed Lateral H-15 into Lake Maitland. Maitland Branch is dominated by a variety of emergent and aquatic vegetation. Maitland Branch presently serves a significant function in preserving the waters of Lake Maitland. The water quality of Lake Maitland is presently good. Tests taken within the lake do not reveal violations of the Respondent's water quality rules and regulations. The lake is, however, dominated by hydrilla, and does not support a diverse aquatic plant population. The water quality in Lake Park is inferior to that of Lake Maitland. Lake Park is dominated by algal growths. During periods of high water, the waters of Park Lake flow through Maitland Branch. The aquatic vegetation in Maitland Branch serves to filter the waters and to assimilate nutrients contained in the water before the water enters Lake Maitland. Approximately 27 acres of impervious surfaces adjacent to the Maitland Branch drain directly into the branch. Storm water runs across the surfaces into Maitland Branch generally without the benefit of any filtration mechanism at all. Without the aquatic vegetation present in Maitland Branch, this storm water runoff would enter Lake Maitland without being filtered, and without nutrients being assimilated by vegetation. Aquatic vegetation in Maitland Branch does serve the filtration and assimilative functions outlined above. The degree of filtration and assimilation that is occurring is not subject to any finite measurement. No scientific means exists for accomplishing such a measurement. The very fact that the vegetation is flourishing, provides scientific evidence that the assimilation of nutrients is occurring. Furthermore, the large amounts of toxic substances which enter the Maitland Branch would cause a very rapid and provocative deterioration of the waters of Lake Maitland unless the runoff were filtered. The fact that the water of Lake Maitland is of fairly good quality evidences the fact that filtration and assimilation functions are occurring in Maitland Brunch. The Petitioner sought to demonstrate that the aquatic, vegetation in the Maitland Branch does not serve to filter the waters, or to assimilate nutrients. Petitioner's testimony tends to show that the water quality of waters at the Park Lake outfall and at the western extremes, of the Maitland Branch are of higher quality than waters at the end of Maitland Branch closest to Lake Maitland. This evidence is not creditable. In the first place the sampling techniques used by the Petitioner's agents were inadequate. Too few samples were taken to permit the drawing of any proper scientific conclusions. The samples were not taken simultaneously and in some cases samples taken at the Park Lake outfall were taken several days prior to the taking of samples at sampling stations closer to Lake Maitland. Furthermore, samples were taken at times when vegetation in the Maitland Branch was most sparse. One group of samples was taken just subsequent to a freeze which killed all of the vegetation. Another group of samples was taken shortly after the Petitioner had removed vegetation from the Maitland Branch in accordance with a temporary permit that had been issued by the Respondent (see discussion in paragraph 9 infra) Even if the Petitioner's samples had been taken in such a way that the conclusion could be drawn that the water quality in Maitland Branch is worse close to Lake Maitland that it is at the Park Lake outfall, it would still be clear that the aquatic vegetation in the branch is performing its important environmental function. Runoff from adjacent impervious surfaces into Lake Maitland constitutes water of the poorest possible quality. It is thus to be expected that the water quality of the branch would be worse at the points farthest from the Park Lake outfall where more runoff water can accumulate. This does not however permit the conclusion that no filtration and assimilation is occurring, but rather amplifies the necessity for such functions if the water quality of Lake Maitland is to be preserved. Petitioner's proposed Lateral H-15 would constitute a source of pollution for the waters of Lake Maitland. The concrete bottom of Lateral H-15 would reduce the PH level of water the branch and could result in violations of PH standards set out in the Respondent's rules and regulations. Emergent and attached aquatic vegetation could not exist in Lateral H-15. There would be no place for such vegetation to take root. The only sort of vegetation that could take hold would be water hyacinths. During peak water flows these hyacinths would be flushed out of the branch into Lake Maitland. While water hyacinths do serve to filter water that flows through them and to assimilate nutrients from the water, they are not attached, and do not serve that function as well as attached aquatic vegetation. Since water hyacinths would be washed out of the branch during periods of heavy storm runoff, when filtration and assimilation are most essential, they would not be likely to serve to maintain the water quality of Lake Maitland to the extent that the present vegetation in Maitland Branch serves this function. Lateral H-15, with the reduced ability to preserve water quality would permit water of inferior quality from Park Lake to enter Lake Maitland, and would permit storm runoff with high levels of pollutants to enter Lake Maitland. The amount of injury to water quality in Lake Maitland that would result from replacing Maitland Branch with Lateral H-15 cannot be measured finitely. It is, however, clear from the evidence that injury is certain. The frequency of water quality violations, the degree of degradation of the water, and the amount of consequent harm to fish and wildlife in Lake Maitland that will result from Petitioner's proposed project are matters for speculation. It does appear that violations will occur, that the water will be degraded, and that fish and wildlife will be harmed. The testimony will clearly not support a finding that Petitioner has given reasonable assurance that water quality violations will not occur, that the quality of water will not be degraded, and that fish and wildlife will not be harmed. The Respondent within recent months had issued a permit allowing the Petitioner to remove aquatic vegetation from the Maitland Branch between the railroad which crosses the branch near to the Park Lake outfall , and Highway 17-92 which crosses the branch approximately halfway between Park Lake and Lake Maitland. Issuance of this permit does not demonstrate that the Respondent sees no value in the aquatic vegetation of Maitland Branch. Aquatic vegetation will rapidly reestablish itself in the area, and it will be missing for only a temporary period. In addition, the Petitioner was permitted to remove vegetation from less than half of the length of Maitland Branch.
The Issue The issue in this proceeding is whether the District should approve FRI's consumptive use permit application, no. 2-019-0012AUR, pursuant to Chapter 40C- 2, Florida Administrative Code The FRI is seeking permission to withdraw an annual average daily rate of million gallons per day (mgd) of water and 762.85 million gallons per year of ground water for hydraulic dredging, cleaning and purification of sand at the Goldhead Sand Mine. Subject to certain limiting conditions to be set forth in the FRI's consumptive use permit, the water is proposed to be produced from three Floridan aquifer wells. District proposed to grant the permit application which was challenged by LBCA, resulting in the formal administrative proceeding. LBCA challenged the issuance of the permit to FRI on the basis of the FRI's alleged failure to comply with the applicable requirements of Chapter 3V3, Florida Statutes (E.S.), and Chapter 40C-2, Florida Administrative Code (F.A.C.), and other applicable law. RULINGS ON EXCEPTIONS TO FINDINGS OF FACT LBCA Exception Number 1 The LBCA takes exception to the hearing officer's Finding of Fact 2 that a necessary component of FRI's operation is its withdrawal of approximately 2.09 mgd of ground water for the production of sand. The 2.09 mgd is the average daily usage rate to who the parties stipulated prior to the hearing. The maximum daily usage rate is 3.75 mgd. However, FRI cannot exceed 762.5 million gallons for the year which is an average of 2.09 mgd. (Prehearing Stip. pp. 1,9). In the LBCA Proposed Recommended Order paragraph 25, the LBCA states that the operation "necessitates FRI's pumping allocation of an average daily 2.09 million gallons of water from the Floridan aquifer." Additionally, LBCA acknowledges in its Exception No. 2 that it is "known that approximately 2 mgd are pumped into the system." If a hearing officer's finding is supported by any competent substantial evidence from which the finding could reasonably be inferred, then it cannot be disturbed. Berry v. Dept. of Environmental Regulation, 530 So.2d 1019 (Fla. 4th DCA 1988). This exception is rejected because the finding is supported by competent substantial evidence. (T. 41-42, 104, 913-914). LBCA Exception Number 2 The LBCA takes exception to the hearing officer's Findings of Fact 8 and 28 that the receiving water from the mine site is primarily the surficial aquifer which recharges the downgradient lakes and that the surficial aquifer recharge will result in a positive or immeasurable effect on the lakes. The exception goes to the weight of the evidence and inferences drawn there from by the hearing officer. It is improper for this Board to retry the case after the hearing has concluded by altering findings supported by evidence and reweighing evidence. Tampa Wholesale Liquors, Inc. v. Div. of Alcoholic Beverages and Tobacco, 376 So.2d 1195 (Fla. 2d DCA 1979). The decision to believe one expert over another is left to the hearing officer, and the decision cannot be altered absent a complete lack of competent substantial evidence from which the finding could be reasonably inferred. Fla. Chapter of Sierra Club v. Orlando Utility Comm., 436 So.2d 383, 389 (Fla. 5th DCA 1983) This Board cannot reweigh conflicting evidence, judge credibility of witnesses, or otherwise interpret the evidence to reach a desired result. Heifetz v. Dept. of Business Regulation, 475 So.2d 1277 (Fla. 1st DCA 1985); Freeze v. Dept. of Business Regulation, 556 So.2d 1204 (Fla. 5th DCA 1990). If a hearing officer's finding is supported by any competent substantial evidence from which the finding could reasonably be inferred, then it cannot be disturbed. Section 120.57(1)(b)10., Fla. Stat.; Berry v. Dept. of Environmental Regulation, 530 So.2d 1019 (Fla. 4th DCA 1988). This exception is rejected because the findings are supported by competent substantial evidence. (T. 105, 120-129, 146, 170, 187-190, 208-209, 235, 248, 256-257, 972-973, 1085-1093, 1139). LBCA Exception Number 3 The LBCA takes exception to the hearing officer's Finding of Fact 11 that the aquifer characteristics in the Floridan aquifer beneath and around the mine site are relatively uniform. The exception goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 180, 926-927). LBCA Exception Number 4 The LBCA takes exception to a mischaracterization of the hearing officer's Finding of Fact 13 regarding lake leakance by stating that the hearing officer found that some of the lakes at issue do not have leakance to the Floridan aquifer. In fact, it is contextually clear that the Hearing Officer was referring to "many of the lakes within the region." This exception goes to the weight of the evidence and inferences drawn there from by the hearing officer. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 77-80). LBCA Exception Number 5 The LBCA takes exception to the hearing officer's Finding of Fact 16 that very little, if any, of the groundwater flowing into the Floridan aquifer beneath Lake Brooklyn flows toward the mine site. In making its argument, LBCA inaccurately attributes testimony to FRI witness Fountain when the referenced testimony was testimony of LBCA witness Boyes. This exception goes to the weight of the evidence and inferences drawn there from by the hearing officer. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 1145-1146). LBCA Exception Number 6 The LBCA takes exception to the hearing officer's Findings of Fact 22 and 55 that the data collection effort of FRI and the District was far more extensive than is normally conducted for a mine of this size and that sufficient site-specific information was developed to be able to determine the effects of the proposed use of water at the mine operation. This exception goes to the weight of the evidence and inferences drawn there from by the hearing officer. The findings are supported by competent substantial evidence and therefore the exception is rejected. (T. 103, 201, 238, 918-919; FR Ex. 5). LBCA asserts that FRI did not evaluate the "worstcase" scenario in order to establish permit entitlemet LBCA provides no legal citations to support its exception. LBCA's assertion lacks legal as well as factual support. LBCA has criticized FRI's aquifer performance test and modeling effort without presenting the elusive "worstcase scenario" which presumably would show impacts greater than those modeled by FRI. LBCA seeks to impose a burden of proof which is insupportable in law. It is not FRI's burden to show a violation of the criteria in Chapter 40C-2, Fla. Admin. Code, is a scientific impossibility, only to show that the non-occurrence of such violation is reasonably assured by the preponderance of the evidence in the proceeding. The Corporation of the President v. SJRWMD and City of Cocoa, Case Nos. 89-828, 89-751 (SJRWMD Dec. 13, 1990), aff'd, 590 So.2d 427 (Fla. 5th DCA 1991). An agency cannot assume the worst-case scenario unless that condition is reasonably foreseeable. Florida Audubon Society, supra..; Rudloe and Gulf Stream Specimen Co. v. Dickerson Bayshore, Inc., 10 F.A.L.R. 3426 (Florida Department of Environmental Regulation, June 8, 1988). As delineated in FRI's response to this exception, FRI and the Distract presented evidence of numerous investigations regarding this application, including testing and analyses of the impact of withdrawals at greater than the average and maximum daily pumping rates. (See Record citations on pp 17-20 of FRI's Response to Exceptions; T. 115-116, 126, 176-177, 918- 920). LBCA failed to present any citation to the record where it presented testimony evincing that another scenario which would result in greater impacts than those predicted by the applicant were reasonably like to occur. LBCA's speculation that another undefined scenario of pumping would show greater impacts was rejected by the hearing officer. The applicant has provided reasonable assurances with regard to the effects of the proposed withdrawal. LBCA Exception Number 7 The LBCA takes exception to the hearing officer's purported inference in Finding of Fact 23 that the aquifer performance test (2T) measured impacts significantly greater than could be expected to occur under "worst case" conditions as a result of the mining operation. The finding actually states "the (aquifer performance) test measured effects of pumping from the mine production wells for periods ranging from 78 hours to 108 hours at approximately twice the average rate of 2.09 mgd." As discussed in the ruling on exception no. 6, LBCA's assertion of a "worstcase scenario" has factual support in the instant case. The applicant is required to provide reasonable assurance that the proposed use is reasonable, beneficial, will not impact existing legal uses and is consistent with the public interest. The applicant is not required to evaluate LBCA's unspecified worst case scenario or prove the use will not cause any impacts. Florida Audubon Society, supra..; Rudloe, supra.. This exception goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 113-115, 141, 920). LBCA Exception Number 8 The LBCA takes exception to the hearing officer's Finding of Fact 23 that no changes in the lake levels are attributable to the pumping at the mine. This exception goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. In Finding of Fact No. 24, the hearing officer found that the effects of pumping were not distinguishable from the declines which occurred before and after the ADT test. Therefore, his conclusions are not inconsistent as alleged by the LBCA. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 120-130, 146, 759, 928- 933, 942, 944- 948, 1015-1016, 1122-1123, 1168; Dist. Ex. 5). LBCA Exception Number 9 The LBCA takes exception to the hearing officer's Finding of Fact 24 that the actual effects of the pumping will be approximately one half of the observed amounts of the 2T test on an average pumping day. This exception goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 113-117, 923-996; Dist. Ex. 5). LBCA's claim that this finding is irrelevant since only a "worstcase" scenario is pertinent is likewise rejected. Initially, it is noted that LBCA cites no legal support for its arguments. Furthermore, there is no requirement in the District's rules governing consumptive use which mandates consideration of only "worstcase" scenarios. Furthermore, an agency cannot assume worst case scenarios unless they are reasonably foreseeable, which determination is a case by case factual issue. See Florida Audubon Society, supra., Rudloe, supra.. LBCA Exception Number 10 The LBCA takes exception to the hearing officer's Finding of Fact 26 that Dr. Stewart testified that the Floridan aquifer is rarely completely homogenous and isotropic but that he and other modelers regularly make that assumption. This Board cannot judge credibility of witnesses or otherwise interpret the evidence to reach a desired result. Heifetz, supra.; Freeze, supra.. This exception goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. The finding supported by competent substantial evidence and therefore the exception is rejected. (T. 738). LBCA Exception Number 11 The LBCA takes exception to the hearing officer's Finding of Fact 27 that the maximum drawdown in the Floridan aquifer under normal pumping conditions is modeled to be 0.1 to 0.2 feet beneath White Sands Lake. This exception goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 129, 182). For the same reasons stated in the ruling on exceptions no. 9 and 7, the LBCA's claim regarding irrelevancy is rejected. LBCA Exception Number 12 The LBCA takes exception to the hearing officer's Finding of Fact 28 that a decrease in lake levels will be less than that of the decrease in the Floridan aquifer, depending on the rate of leakance and that the drawdown effect will not accumulate over time, but rather will remain constant after reaching steady state conditions. The LBCA is simply rearguing their case. This Board cannot reweigh conflicting evidence, judge credibility of witnesses, or otherwise interpret the evidence to reach a desired result. Heifetz, supra.; Freeze, supra.. This exception goes to the weight of the evidence and inferences drawn there from by the hearing officer. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 118-120, 129, 237, 706-708, 758). LBCA's irrelevancy argument is rejected for the reasons stated in the ruling on exceptions no. 9 and 7. LBCA Exception Number 13 The LBCA takes exception to the hearing officer's Findings of Fact 42 through 54 as being conclusion of law rather than findings of fact. The LBCA does not cite to the record or make legal argument to support the exception as required by Rule 40C-1 .564, F.A.C. Without said citation or argument, the exception is rejected. Corporation of the President, supra.. The hearing officer's recitation of the individual criteria of Rules 40C-2.301 (2), (4) and (5), F.A.C., serve as introduction to and reference for the specific findings with regard to each criterion to provide clarity in the order. To the extent that expert witnesses presented testimony on the criteria and how the applicant satisfied the criteria through proof, the elements are findings or fact. These additional reasons also serve as ground for rejection of the exception. LBCA Exception Number 14 The LBCA takes exception to the hearing officer's Finding of Fact 56 that LBCA's referenced exhibits do not correlate with normal conditions when compared with longer periods of time. The exception goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. The finding is supported by competent substantial evidence and therefore the exception is rejected. In addition, the hearing officer ultimately did not admit the exhibits and therefore, the Finding of Fact becomes irrelevant. (T. 1152-1168, 411-416, 930- 933, 948, 969; FR Ex. 50A, SOB). Contrary to Rule 40C-1.564(3), F.A.C., LBCA fails to state wish particularity citations to the record or legal basis as required by Rule 40C-1.564, F.A.C., in support of its attack on finding 56 and its inferential attack on findings 23, 24, 30, 31, 32, 33, 34 and conclusions 62 and 63. The entire exception is rejected. LBCA Exception Number 15 The LBCA takes exception to the hearing officer's Conclusion of Law 66 that LBCA's exhibits 61, 64, 65, 71, 75, 76, 78-80, 82 and 83 have limited probative value to the extent it is predicated on FRI's rebuttal testimony. The LBCA argues that the rebuttal testimony is of low probative value. This Board cannot reweigh conflicting evidence, judge credibility of witnesses, or otherwise interpret the evidence to reach a desired result. This exception goes to the weight of the evidence and inferences drawn there from by the hearing officer. The finding is supported by competent substantial evidence and, therefore, the exception is rejected. (T. 1152-1168, 411-416, 930-933, 948, 969). Exception is also taken to Findings of Fact Nos. 32, 36, and 56 and Conclusion of Law 62 because LBCA argues that the testimony on which they are based exceeded the scope of direct examination and the LBCA was not given the opportunity to object. The correct time to object was when the alleged improper testimony was elicited. The LBCA did not object to preserve the record and therefore, has waived the objection. Section 90.104(1)(a), Fla. Stat. Finally, LBCA asserts that it was denied the opportunity to present rebuttal testimony in violation of Section 120.57(1)(b)4., Fla. Stat. To the contrary, LBCA was not denied the opportunity to present rebuttal testimony but failed to request surrebuttal and consequently failed to preserve any denial of that request by an objection on the record. (T. 1188-1190). Since LBCA never requested surrebuttal, the hearing officer never denied that request and, therefore, LBCA's argument is without merit. Furthermore, pursuant to the order of presentation under Rule 40C- 1.5434(1), F.A.C., which is followed in a permitting proceeding (applicant, petitioner, district), LBCA's entire case tended to be in the nature of rebuttal to the applicant's case. While the hearing officer did state that he did not ordinarily allow surrebuttal (T. 1169) before the rebuttal testimony was concluded, LBCA never affirmatively requested to present surrebuttal evidence or testimony nor did LBCA proffer any such evidence or testimony. Since no proffer was made of any relevant surrebuttal testimony which LBCA contends was excluded, and no objection was made in the record to LBCA's belief that it was prohibited from adducing surrebuttal evidence, it is now precluded from complaining about this perceived adverse ruling. King v. Estate of King, 554 So.2d 600 (Fla. 1st DCA 1989); Holmes v. Redland Construction Co., 557 So.2d 911 (Fla. 3rd DCA 1990); Roberts v. Hollway, 581 So.2d 619 (a. 4th DCA 1991); Diaz v. Rodriguez, 384 So.2d 906 (Fla. 3rd DCA 1980). The exception is rejected. LBCA Exception Number 16 The LBCA takes exception to the hearing officer's Findings of Fact 17, 18, 19, 20, 21, 52 and 55 and Conclusions of Law 62 and 63. Findings of Fact 18, 19, 21, 52 and 55 and Conclusions of Law 62 and 63 are discussed in subsequent exceptions and therefore arc not addressed in this ruling on exceptions. LBCA's exception to Finding of Fact 20 fails to state with particularity any supporting citations to the record or legal argument as required by Rule 40C- 1.564 (3), F.A.C., and is therefore, rejected. LBCA takes exception to Finding of Fact 17 that the hearing officer incorrectly refers to three distinct water quality studies. In fact, the hearing officer actually refers to "numerous analyses" LBCA also objects to the reference to "unknown persons" in the finding and apparently to the statement: "They include analyses conducted by the District in 1989 and 1992, including sampling of water quality and an analysis of the background levels of certain parameters, and an assessment of data from HRS testing in March 1989 and May 1992." Clarification that HRS personnel conducted sampling in 1989 and 1992 is provided; however, since these personnel were never specifically named, to that extent the hearing officer's reference to "unknown persons" is accurate. (T. 1035, 379). The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 102-103, 130- 133, 451, 1023-1037, 1041- 1048, 1151-1152). LBCA Exception Number 17 The LBCA takes exception to that part of the hearing officer's Finding of Fact 18 that states: "This theory was predicated on... an assumption that a chemical reaction was occurring because herbicides were used in the dredge pond." LBCA fails to prove any supporting transcript citations in violation of Rule 40C- 1.564 (3), F.A.C. In Finding of Fact 18, the hearing officer reached the conclusion that none of the water quality samples taken from the mine site indicate a violation of state water quality standards. The exception goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. It is improper for this Board to retry the case after the hearing has concluded by altering findings and reweighing evidence. Tampa Wholesale Liquors, Inc., supra.. This Board cannot judge credibility of witnesses or otherwise interpret the evidence to reach a desired result. The finding is supported by competent substantial evidence and the exception is rejected. (T. 133, 575, 1024-1025). LBCA Exception Number 18 The LBCA takes exception to the hearing officer's Finding of Fact 19 by arguing that water quality on the mine site says nothing about off site impacts and positing that the finding is predicated on certain speculation. LBCA offers no helpful record citations supporting these allegations. Expert testimony established that water quality sampling by FRI and the District of the surficial aquifer at the locations chosen was where water quality impacts would be most likely to be revealed and consequently was a conservative approach. (T. 133, 144, 1029-1030, 1061, 1073). This exception goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 130-139, 141-144, 575-576, 1028-1031, 1061-10 65, 1073, 1136-1139). LBCA Exception Number 19 The LBCA takes exception to the hearing officer's Finding of Fact 21 by stating that it misleadingly implies that 212 homes were tested for water quality by HRS. To the contrary, the hearing officer's finding states "12 out of 212 homeowners" (emphasis added) south of the mine site were tested, not 212. In addition, the exhibits referenced do not reflect the testing of 212 homes. The finding is supported by competent substantial evidence and the exception is rejected. (T. 167-168, 379, 990, 1036-1037, 1041, 1048-1050, 1052-1053). LBCA Exception Number 20 The LBCA takes exception to the hearing officer's Finding of Fact 21 on the basis that it is a legal conclusion which misrepresents and misapplies the state water quality standards. However, LBCA cites no authority or record citation for the argument as required by Rule 40C-1.564(3), F.A.C. The finding actually states "with the exception of one well... the water from the homeowners' wells did not exceed background water quality for iron and manganese"; clearly, this is a factual statement. This exception, under the guise of an unsupported legal argument, goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. The finding is supported by competent substantial, and uncontroverted, evidence which, incidentally, includes explanation and citation to the relevant exception/standard. Furthermore, the parties stipulated that official recognition was taken of chapter 17-520, F.A.C. The exception is rejected. (T. 1034, 1041, 1077-1078; Prehearing Stip. p 12; Rules 17- 520.420(2) and 17-520.200(11), F.A.C.) LBCA Exception Number 21 The LBCA takes exception to the hearing officer's Finding of Fact 21 that the 1989 water quality samples by HRS were unreliable because of the uncertainty regarding the sampling technique protocol. This exception erroneously states there was no evidence of sampling protocol used by HRS. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 1039-1049). LBCA Exception Number 22 The LBCA takes exception to the hearing officer's Finding of Fact 52 that the receiving body of water will not be seriously harmed, by characterizing the finding as being predicated on an unproven theory that the surficial aquifer receives all groundwater discharged from one site. LBCA has failed to read the entire finding which clearly reveals that the hearing officer did not confine his consideration to the surficial aquifer. He found that water quality standards would not be violated in the surfical aquifer, where the highest concentrations of any potential contaminants would appear, then they would not be violated in any intermediate aquifer similarly, no violations would occur in one Floridan aquifer. The decision to believe one expert over another is the role of the hearing officer, and the decision cannot be altered absent a complete lack of competent substantial evidence from which the finding could be reasonably inferred. Fla. Chapter of Sierra Club, supra.. This Board cannot reweigh conflicting evidence, judge credibility of witnesses, or otherwise interpret the evidence to reach a desired result. Heifetz, supra.; Freeze, supra.. If a hearing officer's finding is supported by any competent substantial evidence from which the finding could reasonably be inferred, then it cannot be disturbed. Berry, supra.. This exception goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 105, 141-142, 1025-1030, 1034-1035). LBCA Exception Number 23 The LBCA takes exception to the hearing officer's Finding of Fact 55 that water quality sampling was collected to evaluate a water budget for the dredge pond. In their responses to this exception, FRI explicitly notes it has no response to this exception and District counsel concedes that although water quality samples were taken from the dredge pond and a water budget was calculated for the dredge pond, these two procedures were not linked to one another. The testimony of FRI witnesses is that water quality sampling and data to determine the water budget for the dredge pond were performed. (T. 76, 103). Counsel for FRI and the District have stipulated that the testimony does not support the finding that the water quality samples were used to evaluate the water budget. Since, as stipulated, this portion of the hearing officer's finding is not supported by any evidence in the record, the exception is accepted. LBCA Exception Number 24 The LBCA takes exception to the nearing officer's Finding of Fact 55, arguing that the applicant did not perform an environmental assessment of Lake Brooklyn, and thus cannot fairly draw any conclusions about its operation's impact on that lake. The Finding of Fact describes the site-specific information which supports the application. The pertinent part of the finding states: "FRI conducted an assessment of the environmental impacts to the wetland and wildlife resources of the area lakes, including White Sands, Spring and Gator Bone Lakes." To the extent Lake Brooklyn is encompassed by use of the term "area lakes", the existence of an assessment of the impacts to Lake Brooklyn is supported by expert testimony. (T. 281, 899). Additionally, the finding is otherwise supported by competent substantial evidence. (T. 266-280). The exception is rejected. LBCA Exception Number 25 The LBCA takes exception to the hearing officer's Finding of Fact 31 which states in pertinent part: "petitioner's witness Dr. Stewart opined that there is insufficient data to determine whether any impacts to lake levels are occurring." LBCA is essentially complaining that the entirety of Dr. Stewart's testimony should be credited not just a portion. The role of the hearing officer is to consider and weigh all the evidence, resolve conflicts and judge credibility of the witnesses. The hearing officer apparently did not view all of Dr. Stewart's testimony in the same manner as LBCA's attorney; such is his legal prerogative. If a hearing officer's finding is supported by any competent substantial evidence from which the finding could reasonably be inferred, then it cannot be disturbed. Berry, supra.. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 784-786, 145- 146, 232-233, 285-286, 288-289, 897-898, 1085). LBCA Exception Number 26 The LBCA takes exception to the hearing officer's Finding of Fact 24 that the rate of decline (in Spring, White Sands and Gator Bone Lakes) during the APT test was not distinguishable from the declines which occurred before or after the test. LBCA provides no record citations to support its argument that since the hearing officer rejected its use of certain APT data in an attempted correlation between pumping and Lake Brooklyn levels, that all the APT data was entirely discredited and could have no value in an analysis regarding Spring, White Sands or Gator Bone Lakes. If a hearing officer's finding is supported by any competent substantial evidence from which the finding could reasonably be inferred, then it cannot be disturbed. Berry, supra.. This exception goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. The finding is supported by competent substantial evidence and therefore the exception is rejected. (T. 941-948, 1015-1016, 1123, 1168). RULINGS ON EXCEPTIONS TO CONCLUSIONS OF LAW LBCA Exception Number 1 The LBCA takes exception to the hearing officer's Conclusion of Law 62 and 63 and Findings of Fact 42 through 54 (which LBCA alleges should be conclusions of law) that FRI has established its entitlement to the permit. LBCA argues that the applicant failed to present sufficient information about conditions at Lake Brooklyn. LBCA's numerous "factual" statements in this exception are unsupported by record citations. The burden of proof in an administrative hearing falls initially upon the party asserting the affirmative of an issue, i.e. entitlement to a permit. Rules 40C-1.545 and 40C-2.301(7), F.A.C.; Capeletti Brothers v. Department of General Services, 432 So.2d 1359 (Fla. 1st DCA 1983); Department of Transportation v. J.W.C., Inc., 396 So.2d 778 (Fla. 1st DCA 1981). The party must prove its case by a preponderance of the evidence. Florida Audubon Society v. South Florida Water Management District, 13 F.A.L.R. 4169 (undated). The applicant's burden is to establish reasonable assurances that the proposed use is a reasonable-beneficial use, will not interfere with any presently existing legal use of water, and is consistent with the public interest. Section 373.223, Fla. Stat. The burden of reasonable assurances is not one of absolute guarantees. City of Sunrise v. Indian Trace Community Dev. Dist., 14 F.A.L.R. 866 (January 16, 1992). The impacts which are reasonably expected to result from issuance of the permit must be addressed, not potential impacts or those that might occur Hoffert v. St. Joe Paper Co., 12 F.A.L.R. 4972 (December 6, 1990); Chipola Basin Protective Group Inc. v. Florida Chapter of Sierra Club, 11 F.A.L.R. 467 (Department of Environmental Regulation, December 29, 1988); Florida Keys Citizen Coalition v. 1800 Atlantic Developers, 8 F.A.L.R. 5564 (Department of Environmental Regulation, October 17, 1986). Once the party asserting the affirmative, FRI, has presented its prima facia case, the burden shifts to the LBCA to present contrary evidence. 1800 Atlantic Developers, supra.; Hoffert, supra.. LBCA cites Booker Creek Preservation, Inc. v. Mobil Chemical Co., 481 So.2d 10 (Fla. 1st DCA 1986) in support of the exception. In Booker Creek, the Court held that additional testing, beyond that offered by the applicant, should have been done before the permit could be issued. Booker Creek was limited to its unique set of facts by the case of Berry v. Dept. of Env. Regulation, 530 So.2d 1019 (Fla. 4th DCA 1988). The Berry Court, in dealing with a dredge and fill permit, refused to extend the Booker Creek holding to such permits, noting that the permit under consideration in Berry, was not a pollutant discharge permit. The permit in issue here also is not a pollutant discharge permit. More importantly, like the applicant in Berry, FRI offered evidence of extensive testing and analysis regarding where water comes from and goes to at the mine site and in the surrounding vicinity. Finding of Fact No. 55. LBCA incorrectly argues that the modeling information submitted by FRI has no applicability to impacts at Lake Brooklyn, because the model "did not include Lake Brooklyn". Particularly, in view of findings of fact 23, 28, 31-36 (exceptions to which have been previously rejected), it is apparent that the hearing officer rejected LBCA's view of the "facts" stated in this exception. While the model boundary (which is based on water level data for Floridan wells in the region (T. 164)) is between Lake Brooklyn and the pumping wells at the mine, the drawdown at the model boundary is based on a distance-drawdown relationship that relates to the pumping rate at the mine. The 1991 transient model showed that within the 9 square mile boundary, the impacts at the boundary were no more than 0.1 feet. (T. 129, 178). The reduced boundaries in the 1992 model accurately predicted what was happening at the mine site. (T. 178). The distance-drawdown relationship established by the model shows that the drawdown contour ceases before the model boundary is reached and therefore, before Lake Brooklyn is reached. (FR Exs. 5, 22). Impacts to Lake Brooklyn were also assessed through the review of water levels in the Floridan aquifer well (C- 120) between 1960 and 1992. (T. 928-933). The data showed that water levels in the well at Lake Brooklyn actually continued to rise when the 1989 and 1991 pump tests were conducted. (T. 411-412, 931-933; SJRWMD Ex. 13). In addition, when the pumping wells at the mine were turned off, the water level in the well at Lake Brooklyn did not recover. This indicates that there were outside influences for the fluctuation in the well. (T. 415, 933). The data does not show impacts from the pumping at the sand mine. (T. 942). LBCA also erroneously states that groundwater in the Floridan aquifer beneath Lake Brooklyn flows toward the mine. (See ruling on LBCA's factual exception 5). As listed in responses to LBCA's factual exceptions, particularly those regarding exceptions 8 and 12, there is competent, substantial evidence to support the bindings regarding no adverse impact to Lake Brooklyn. The hearing officer found that the applicant met its burden or proof in Conclusion of Law 62. In Conclusion of Law 63, the hearing officer concluded that the LBCA did not meet its burden of presenting contrary evidence that the withdrawals at the sand mine correlate with the decline in water levels at Lake Brooklyn. The exception goes to the weight of the evidence and inferences drawn therefrom by the hearing officer. This Board cannot reweigh conflicting evidence, judge credibility of witnesses, or otherwise interpret the evidence to reach a desired result. Heifetz, supra.; Freeze, supra.. This exception is rejected. LBCA Exception Number 2 The LBCA takes exception to the hearing officer's Conclusion of Law 63 that additional permit conditions in the case of a water shortage or a shorter permit duration are not necessary. The LBCA is reargue their case in the exception. The District has authority to require FRI to reduce its water use during a water shortage within the seven year life of the permit. Sections 373.175 and 373.246, Fla. Stat., and Rules 40C-2.381(2)(a)2. and 40C-21.271, F.A.C. Rule 40C-2.381(2)(a)2., F.A.C., which is incorporated into the permit as a limiting condition, states: Nothing in this permit should be construed to limit the authority of the St. Johns River Water Management District to declare a water shortage and issue orders pursuant to section 373.175, F.S., or to formulate a plan for implementation during periods of water shortage, pursuant to section 373.246, F.S. In the event a water shortage, is declared by the District Governing Board, the permittee must adhere to the water shortage restrictions, as specified by the District, even though the specified water shortage restrictions may be inconsistent with the terms and conditions of this permit. (emphasis added). Rule 40C-21.271, F.A.C., General Water Use Restrictions, specifies the restrictions which may be imposed during a water shortage on all water users and states, in pertinent parts: The Board may order use of general water use restrictions and the water use restrictions specified in Part VI for the appropriate water shortage phase for each affected source class. Further, the Board may order any combination in lieu of or in addition to the restrictions specified in Part VI of the restrictions described in Subsection (3), by use or method of withdrawal class, within each source class, if necessary to achieve the necessary percent reduction in overall demand. (emphasis added). General water use restrictions which may be imposed include provisions that facilitate the right of water users in an area to make voluntary agreements among themselves, with the concurrence of the Board or the Executive Director, providing for the mutual reduction, sharing, or rotation of use; restrictions on the total amount of water that may be used, diverted, impounded, extracted, or withdrawn during any day, month, or year during the declared shortage; restrictions on the timing of use, diversion, impoundment, extraction, or withdrawal of water; restrictions on pumping rates and schedules or diversion rates and schedules; or such other provisions or restrictions as are necessary to protect the water resources from serious harm. With the above cited authority, the District can require the withdrawals at the sand mine to be reduced during periods of water shortage within the seven year term of the permit by reducing the total amount withdrawn, controlling the schedule of withdrawals or "by other restrictions which arc necessary to protect the water resources." The hearing officer's conclusion is consistent with the rules and statutes which govern the Board. The exception is rejected. LBCA Exception Number 3 The LBCA takes exception to the hearing officer's Conclusion of Law 63 and Finding of Fact 47 that FRI satisfied the criteria regarding water conservation measures. See Rule 40C-2.301(4)(e), F.A.C. The LBCA reargues the facts which the hearing officer found to support the conclusion. However, the LBCA offered no evidence to rebut the testimony of FRI. In addition, the LBCA cites no authority that the hearing officer's conclusion is contrary to law. Florida Audubon Society v. Department of Environmental Regulation, 9 F.A.L.R. 565 (October 31, 1986). LBCA also renews its attack on the allocation amount, essentially iterating its factual exception which is rejected for the reasons set forth therein. It is improper for this Board to retry the case after the hearing has concluded by altering findings and reweighing evidence. Tampa Wholesale Liquors, Inc., 376 So.2d 1195 (Fla. 2d DCA 1979). LBCA's exception lacks any record citations or legal authority in support of this exception. The conclusion and finding are supported by competent substantial, and uncontroverted, evidence and the exception is rejected. (T. 43-52, 106, 234- 237, 988-989, 1103- 1104, 1111, 1132-1133) LBCA Exception Number 3 (sic). The LBCA takes exception to the hearing officer's Conclusion of Law 63, by arguing that the use of water from the surficial aquifer requires a separate permit. Section 40C-2.051, F.A.C., states: No permit shall be required under the provisions of this rule for the following water uses: Withdrawals of ground or surface water to facilitate construction on or below ground surface ..., in the following circum- stances: ground water may be withdrawn if it is recharged on site to the aquifer from which it was withdrawn by either infiltration or direct injection; surface water may be withdrawn only from wholly owned impoundments or works which are no deeper than the lowest extent of the uppermost water bearing stratum and which have no surface hydrologic connection off site, and the surface water must be recharged on site to the uppermost water bearing stratum by either infiltration or direct injection. This exemption from permitting is applicable here, and therefore, no additional permit is required. An agency's interpretation of its rules is afforded great weight. Franklin Ambulance Service v. DHRS, 45 So.2d 580 (Fla. 1st DCA 1989). LBCA offered no auth-orty or evidence that the District's interpretation is contrary to established law. This conclusion is supported by competent substantial evidence. The exception is rejected. (T. 38-39, 105, 249, 972, 1101-1102). RULINGS ON EXCEPTION TO CONCLUSIONS OF LAW CONTAINED IN POST- HEARING EVIDENTIARY RULING LBCA excepts the hearing officer's rulings in Finding of Fact No. 56 and Conclusion of Law No, 66 excluding LBCA exhibits nos. 61, 64, 71, 75, 76, 78, 79, 80, 82 and 83 as inadmissible for failure of LBCA to comply with subsection 90.956, Fla. Stat., regarding use of summaries of evidence. LBCA takes exception to FRI's objection post-hearing alleging that the exhibits had been admitted. In fact, the exhibits were not admitted at hearing. The LBCA's citation to the transcript is not the hearing officer's ruling on the exhibits. The hearing officer did not admit the ten exhibits on the record, as he did with every other exhibit that he admitted. The LBCA's assertion that it believed the exhibits were admitted is belied by LBCA's failure to list them as admitted in its Proposed Recommended Order on page 3. Therefore, LBCA's claim that FRI's continuing objection was a surprise is without merit. LBCA asserts that FRI cannot make a post-hearing objection to the exhibits in its Proposed Recommended Order and infers gnat FRI's objection to the admission of the exhibits was not preserved at hearing. Rule 40C-1.561, F.A.C., provides for the submission of legal briefs along with proposed findings of fact and conclusions or law. For matters that remain pending at the close of a hearing, a party may file a legal brief in support of its position. FRI did not object to the opinion testimony of the LBCA expert witness, only to the graphic depictions of such testimony. (T. 356). LBCA stated at hearing that the excluded exhibits were simply graphic depictions of the expert's opinion testimony. (T. 354). The record is abundantly clear that FRI preserved its objection to the exhibits and the hearing officer reserved ruling on their admission until the recommended order was issued. (T. 353, 358, 360, 363, 369, 370, 375, 377, 524, 531, 537, 1079-1080, 1178). LBCA essentially asserts that the exhibits are not "summaries" and therefore not subject to subsection 90.956, Fla. Stat., which, of course, the fact-finder found otherwise. LBCA's reliance on Marks v. Marks, 576 So.2d 859 (Fla. 3d DCA 1989) is misplaced. Marks did not hold that expert testimony is not subject to subsection 90.956, but only that an expert is not required to utilize subsection 90.956 when presenting underlying data relied on for his opinion. The hearing officer found that the hydrographs were summaries and the underlying information was not indicated on the summary. The hearing officer allowed FRI time to review the data and present rebuttal. The fact-finder is entitled to great latitude in admitting or excluding summary evidence. Wright v. Southwest Bank, 554 F.2d 661 (5th Cir. 1977)(trial court without jury is entitled to great latitude covering the admission or exclusion of summary evidence). LBCA has failed to show that the hearing officer abused this discretion in excluding the exhibits. LBCA also takes exception that LBCA was denied rebuttal, or surrebuttal, on FRI's rebuttal case. As discussed in the ruling on LBCA's Exception 15, LBCA failed to request rebuttal of FRI's case. The hearing officer allowed cross-examination and LBCA did not offer any additional evidence from LBCA witnesses. Since the LBCA never requested to offer rebuttal testimony, then the hearing officer could not and did not deny that request. It is well-settled that an objection must be preserved during an administrative proceeding or it will be deemed waived. DeMendoza v. First Federal Savings and Loan, 585 So.2d 453 (Fla. 4th DCA 1991)(even if mistake was made in trial, party's waived its right to appeal the issue since it failed to call the deficiency to the court's attention during trial); Yachting Arcade, Inc. v. Riverwalk Condominium Assoc., 500 So.2d 202 (Fla. 1st DCA 1986)(party's failure to object to matters at administrative hearing made those matters unreviewable, even though party claimed fundamental procedural errors, it failed to show how it was prejudiced by any such action or omission; National Dairy Products, Corp. v. Odham, 121 So.2d 640 (Fla. 1959). Therefore, LBCA's exception based on the denial of rebuttal is rejected. LBCA argues that-the proper vehicle for the objection was a motion for rehearing. LBCA does not cite authority for its assertion. Since the hearing officer never ruled on the admissibility, there was no order on which to base a motion for rehearing. Nevertheless, the alleged error, if any, of excluding the exhibits, was harmless. Sims v. Brown, 574 So.2d 131 (Fla. 1991)(exclusion of manual was harmless since experts testified to the same matters in the manual); Little v. Banker's National Life Insurance Co., 369 So.2d 637 (Fla. 3d DCA 1979)(harmless error to exclude letter since witnesses otherwise testified at length as to its contents and conclusions). The LBCA expert testified extensively regarding the basis of each excluded exhibit and the information it depicts in relation to the conclusions of his expert opinion which the hearing officer weighed in rendering his factual findings and conclusions. (T. 346, 349, 351, 352, 358, 359, 364, 366, 371, 373, 411, 456, 457, 458, 481, 486, 501, 504, 507, 509, 511, 512, 516, 517, 518, 519, 542). The hearing officer concluded that even if the exhibits had been admitted it would not have altered his factual findings stating that they had limited probative value. (Conclusion of Law No. 66). Therefore, the exception is rejected. RULING ON RECOMMENDED ORDER'S COMPLIANCE WITH SECTION 120.59(2), FLA. STAT. LBCA asserts that the hearing officer failed to comply with subsection 120.59(2), Fla. Stat., by not providing a sufficiently explicit ruling on each of the parties' proposed findings of fact. Section 120,59(2), Fla. Stat., requires "a ruling upon each proposed finding" The Appendix to the Recommended Order does not contain an omnibus "blanket" ruling on all of LBCA's proposed findings which the courts have found inadequate. Cf. Island Harbor beach Club v. DNR, 476 So.2d 1350 (Fla. 1st DCA 1985); Health Care Management, Inc. v. DHRS, 479 So.2d 193 (Fla. 1st DCA 1985). The Appendix clearly contains a ruling upon each of LBCA's proposed findings. Section 120.59(2), Fla. Stat., requires no more. LBCA relies on Island Harbor Beach Club v. DNR, 476 So.2d 1350 (Fla. 1st DCA 1985), to support this argument. Island Harbor Beach Club, differs significantly from this case. The order Island Harbor Beach Club did not individually address each specific proposed finding as the Recommended Order in this case does. The only reference to proposed findings made in the Island Harbor Beacon Club order was a single paragraph which stated: The parties proposed findings of fact have been considered and where unsupported by the weight of the evidence, immaterial, cumulative, or subordinate. This differs from the Recommended Order in the instant case which specifically addresses each proposed finding and specifies where (by paragraph) in the Recommended Order that proposed finding is addressed. It is elementary to then read the paragraph referred to in the Recommended Order to determine what portion of the proposed finding was accepted. More applicable to this case is the case of Schomer v. Department of Professional Regulation, 417 So.2d 1089 (Fla. 3d DCA 1982). The order in Schomer did not contain specific rulings on each proposed finding submitted by the Appellant. The substance of the final order, however, demonstrated that each finding had been considered and ruled on. The Court noted that, for purposes of complying with Section 120.59(2) Fla. Stat., It would not elevate form over substance." An agency need not Independently quote verbatim each proposed finding and independently dispose of that proposed finding; rather, it is sufficient that the agency provide in its decision a written foundation upon which the reviewing court may assure that all proposed findings of fact have been consider and ruled upon and not overlooked or concealed. Id. at 1090. The Court held that it could discern from the substance of the order that each of the proposed findings were addressed, and to the extent the technical requirements of Section 120.59(2), Fla. Stat., were departed from, the departure did not materially impair the fairness or correctness of the proceedings. Id. at 1091. LBCA merely has to compare the hearing officer's findings with its proposed findings to discern those portions accepted. Therefore, the exception is rejected. RULING ON MOTION FOR REMAND Pursuant, to Rule 1.540(b), Fla. R. Civ. P., LBCA has filed a Motion for Remand asserting that newly discovered evidence establishes that a finding by the hearing officer is inaccurate because of allegedly false testimony by District expert witness, Dr. Larry Lee. The hearing officer found that Lake Brooklyn had been in a period of decline before and after the 1989 aquifer pump test and that due to rainfall deficits Brooklyn Bay was separated from the main body of Lake Brooklyn for at least 18 to 24 months before and during the 1989 aquifer performance test. The hearing officer determined that the rate and character of declines during the pumping were not distinguishable from the declines occurring before and after the test. Thus, he found that impacts to Lake Brooklyn water levels from the pumping were indistinguishable from the declines due to drought. (Finding of Fact No. 30). LBCA asserts that a newly discovered Department of Transportation (D.O.T.) survey, dated October 11, 1988, shows that Brooklyn Bay was not segregated from the remainder of the lake due to drought conditions prior to the 1989 aquifer pump test as testified by Dr. Lee and seeks the Board to remand the issue to the hearing officer for consideration of this new evidence. The only reasons for remand regarding fact finding are if an erroneous legal conclusion by a hearing officer warrants taking of evidence on the issue, or if a factual issue was never ruled upon by the hearing officer. See Miller v. Dept. Envt'l Reg., 5504 So.2d 1325 (Fla. 1st DCA 1987)(agency's modification of legal conclusions necessitated factual findings on issue which hearing officer had initially disregarded as irrelevant) and Cohn v. Dept. of Prof. Reg., 477 So.2d 1039 (Fla. 3d DCA 1985)(when the hearing officer fails to find a specific fact, agency must remand to the hearing officer to do so). Clearly, neither of these reasons have any application to Petitioner's arguments. Although subsection 40C-1.512, F.A.C., provides that the Florida Rules of Civil Procedure are applicable to District administrative proceedings to the extent not inconsistent with Chapter 120 or Chapter 40C-1, the applicability of Rule 1.540(b), Fla. R. Civ. P., is problematic and inconsistent with a subsection 120.57 proceeding. First, the civil procedure rule only applies to final judgments and in this subsection 120.57 administrative proceeding LBCA is attempting to apply the civil procedure rule to a nonfinal recommended order. Second, LBCA has not expressly excepted Finding of Fact No. 30 as not supported by competent substantial evidence or that a Board rule or policy has been incorrectly interpreted /1 , but actually seeks the Board to allow LBCA to supplement the record after remand with new facts for the hearing officer to weigh in applying those facts to the applicable District rules. Thus, unlike a trial court, Finding of Fact No. 30 cannot be altered by this Board if supported by any competent substantial evidence. Section 120.57(1)(b)10., Fla. Stat.; Freeze v. Dept. of Business Regulation, 556 So.2d 1204 (Fla. 5th DCA 1990); School Board of Leon County v. Weaver, 556 So.2d 443 (Fla. 1st DCA 1990). The Board may only consider whether the findings actually made by the hearing officer are sustained by the evidence, and whether, if so, they support the recommended legal conclusions. Cohn v. Dept. of Professional Regulation, 477 So.2d 1039 (Fla. 3d DCA 1985). Unlike a judge with plenary and equitable powers in a judicial setting, this Board, under Chapter 120, cannot authorize fact- finding after a hearing's conclusion except in the most narrow circumstances, none of which are applicable to the motion before the Board. Cf. Manasota 88, Inc. v. Tremor, 545 So.2d 439 (Fla. 1st DCA 1989)(may remand if hearing officer makes erroneous legal interpretation); Cohn, supra.. (may remand if a necessary factual issue was not determined by the hearing officer); Friends of Children v. DHRS, 504 So.2d 1345 (Fla. 1st DCA 1987)(may remand if hearing officer makes erroneous evidentiary ruling). In effect, LBCA wants to utilize a civil procedure rule for the Board to authorize additional fact-finding on a matter already considered by the hearing officer regarding a finding supported by competent substantial evidence. Section 120.57, Fla. Stat., simply does not authorize the Board to take such action. Section 120.57(1)(b)10, Fla. Stat.; Dept. of Transportation v. J.W.C. Co., Inc., 396 So.2d 778 (Fla. 1st DCA 1981)(chapter 120 does not allow additional or cumulative evidence on matters already considered and the APA does not envision a never-ending process). Consequently, the application of Rule 1.540(b), Fla. R. Civ. P., is inconsistent with Chapter 120 and LBCA is free to raise any alleged error at hearing on appeal of the final order. Even assuming Rule 1.540(b), Fla. R. Civ. P., is applicable to this subsection 120.57 proceeding, LBCA has failed to clearly establish the extraordinary circumstances warranting the granting of its motion. The material issue of whether FRI's proposed pumping would impact the area lake levels already effected by a rainfall deficit was expressly raised by LBCA in its initial petition for hearing as far back as August 1992 and was also an issue stipulated in the Prehearing Stipulation prior to the February 1993 hearing. (Petition for Administrative Hearing paragraph f. 2, 3, 4.; Prehearing Stip. paragraphs B. 2, G. 1). Consequently, LBCA had over five months prior to hearing to elicit all relevant evidence to that Issue. If Rule 1.540(b) was applicable, LBCA's burden would be to clearly establish the following to receive relief: (1) it must appear that the evidence is such as will probably change the-result if a new trial is granted; (2) that it has been discovered since the trial; (3) that it could not have been discovered before one trial by the exercise of due diligence; and (4) that it is material and not merely cumulative or impeaching. City of Winter Haven v. Tuttle/White Construction Inc., 370 So.2d 829 (Fla. 2d DCA 1979); King v. Harrington, 411 So.2d 912 (Fla. 2d DCA 1982), rev denied, 418 So.2d 1279 (Fla. 1982). The predicate for LBCA's motion is that Dr. Lee's testimony regarding the lake separation was false, therefore LBCA could not have exercised due diligence in discovering the alleged new evidence. LBCA has filed no express exception with record support establishing that Finding of Fact No. 30 is not supported by competent substantial evidence and therefore the Board by law cannot alter that factual finding. Section 40C-1.564(3), F.A.C.; Section 120.37(1)(b)10., Fla. Stat.; Freeze, supra.. Consequently, Dr. Lee's testimony is not false. Importantly, Dr. Lee's testimony was not the only evidence supporting this finding. LBCA's own witness, the president of the association, testified that Brooklyn Bay had been segregated for four or five years from the main part of the lake and that he had been able to walk across the lake without getting wet for the last four or five years. (T. 863, 870). Likewise, LBCA's own expert stated that Lake Brooklyn's condition between 1989 to 1991 had receded to such an extent as it was no longer a continuous lake. (T. 317). Accordingly, the predicate for LBCA's motion is factually inaccurate and misplaced. Furthermore, LBCA must clearly establish that even though the exercise of due diligence before the hearing, it would not have discovered the 1988 D.O.T. survey. Brav v. Electric Door-Lift Inc., 558 So.2d 43 (Fla. 1st DCA 1989)(movant's burden to establish due diligence); Plisco v. Union Railroad Co., 379 F.2d 15 (3d DCA 1967)(motion for new trial on newly discovered evidence is granted only where extraordinary circumstances are present). Even though the effects of FRI's proposed pumping on lake levels in time of rainfall deficit was an issue dating back to August 1992, LBCA asserts that it could not have obtained the survey prior to hearing in February 1993 "because of the logistics of requesting public records and the delay in delivery of same." LBCA could have reasonably anticipated that witnesses would testify regarding the disputed issue, particularly its own witnesses, and obtained the survey with the exercise of due diligence. LBCA offers no basis why D.O.T. would not have supplied the survey as required by law or that LBCA could not obtain it and, in fact, the public records law contains a provision for obtaining immediate relief if a request for records is denied. See subsection 119.11, Fla. Stat. In Florida Audubon Society v. Ratner, 497 So.2d 672 (Fla. 3d DCA 1986), a 1981 judgment had been entered finding that limestone mining would be inconsistent with the water management purposes of a water management district's flowage easement on platiff's property. Plaintiff sought a new trial because of newly discovered opposing evidence in a 1980 Corps of Engineers report on the effects of limestone mining. The trial court denied the motion. The appellate court agreed finding that the granting of such motions was disfavored and that the report was prepared in September 1980 well before the trial and judgment in June 1981 and could have been discovered prior to the with the exercise of due diligence. Likewise in this proceeding, the proffered D.O.T. survey was prepared in October 1988, nearly four and one-half years before the February 1993 hearing and LBCA has failed to show that due diligence would not have discovered the survey prior to the administrative hearing in this proceeding. See also, Morhaim v. State Farm Fire & Casualty Co., 559 So.2d 1240 (Fla. 3d DCA 1990)(no new trial granted based on post-judgment affidavits regarding evidence on known issue that could have been discovered prior to trial). LBCA also asserts that Dr. Lee misrepresented the contents of Clark's "Report of Investigations No. 33-Hydrology of Brooklyn Lake Near Keystone Heights, Florida" regarding its conclusions and his opinion concerning the separation of Brooklyn Bay from Lake Brooklyn and thus prejudiced LBCA's case. LBCA argument is an attack on the weight of the conflicting evidence which is the job of the hearing officer to resolve. An expert witness is not required to disclose the facts and data underlying his opinion. Marks v. Marks, 576 So.2d 859 (Fla. 3d DCA 1991). LBCA could have cross examined Dr. Lee regarding the separation. LBCA was aware of the "Clark Report" (T. 844) and even anticipated testimony regarding water levels in its case in chief (T. 846). Indeed, the report was listed by LBCA as its Exhibit 13 in the Prehearing Stipulation, although LBCA chose not to introduce it into evidence during the hearing. Dr. Lee testified not once but twice about the location of the staff gauge (T. 946 and 962-966). On cross, LBCA did not inquire about the location of the staff gauge or the lack of water beneath the bridge. (T. 991-1017). It was LBCA's burden to challenge the factual basis for Dr. Lee's opinion. City of Hialeah v. Weatherford, 466 So.2d 1127 (Fla. 3d DCA 1985). An insufficiency in the expert opinion offered, if any, should have been addressed in cross-examination by LBCA, not by a post-hearing motion. LBCA alleges that the outcome would be different if the DOT survey were part of the evidence. The Board cannot accept new evidence or rule on the admissibility of evidence which was not presented to the hearing officer. The Finding of Fact to which LBCA refers states six reasons why the correlation between the pumping at the sand mine and its effects on Lake Brooklyn water level were not established. See Recommended Order, Finding of Fact 32. The location of the staff gauge in Brooklyn Bay rather than Lake Brooklyn was one of those six. LBCA's error was in not knowing the location of the staff gauge (T. 418-420) rather than the testimony of Dr. Lee. Therefore, LBCA's allegation that but for the testimony of Dr. Lee, the hearing officer would have found differently is unfounded. The mere chance that the hearing officer might have found differently is insufficient to remand the hearing for additional fact finding. Cluett v. Dep't of Professional Regulation, 530 So.2d 351, 355 (Fla. 1st DCA 1988). The courts look with disfavor on motions based on newly discovered evidence because to look with favor would bring about a looseness in practice and encourage counsel to neglect to gather all available evidence for a first trial by speculating upon the outcome, and then, being defeated, become for the first time duly diligent in securing other evidence to cure the defects or omissions in their showing upon the first trial. Rushing v. Chappell, 247 So.2d 749 (Fla. 1st DCA 1971); Henderson Sians v. Fla. Dept. of Transp., 397 So.2d 769 (Fla. 1st DCA 1981). It is well-settled that no abuse of discretion occurs on the part of an agency by refusing to direct a remand to receive evidence which could have been introduced during the course of the original proceedings. Department of Transportation v. J.W.C., Inc., 396 So.2d 778 (Fla. 1st DCA 1981) LBCA has failed to clearly establish a right to relief and therefore the motion is denied. RULING ON MOTION FOR OFFICIAL RECOGNITION AND MOTION TO SUPPLEMENT THE RECORD LBCA has filed a Motion for Official Recognition and to Supplement the Record seeking the Board to accept into evidence the October 11, 1988 D.O.T. survey which was the subject of LBCA's Motion for Remand and also the U.S.G.S. publication "Report of Investigations No. 33-Hydrology of Brooklyn Lake Near Keystone Heights, Florida", by Clark, also referenced In LBCA's Motion for Remand. The Board is not a fact-finder in this subsection 120.57 proceeding and it is reversible error for the Board to supplement the record through post-hearing evidence. Section 120.57(1)(b)10, Fla. stat., Marks v. Northwest Florida Water Management District, 566 So.2d 46 (Fla. 5th DCA 1990)(court refused to take judicial notice of factual matter based on records that could have been offered at administrative hearing); Nest v. Dept. of Professional Regulation 490 So.2d 987 (Fla. 1st DCA 1986); Shongut v Mark, 173 So.2d 708 (Fla. 3d DCA 1965)(Where matters raised on motion for relief from judgment could have been available to movant during trial proceedings, denial of motion was not abuse of discretion); Weaver, supra.. Moreover, the Motion for Remand has been denied. LBCA's post- hearing motions will be available as part of the record of this proceeding for purposes of any appeal which may be pursued. ACCORDINGLY, IT IS HEREBY ORDERED: The Recommended Order dated June 4, 1993, attached hereto as Exhibit A, is adopted in its entirety except as modified by the final action of the Governing Board of the St. Johns River Water Management District (Ruling on LBCA Exception 23). Florida Rock Industries' application for consumptive use permit no. 2-019-0012AUR is hereby granted under the terms and conditions as provided herein. The post-hearing Motion for Remand, Motion for Official Recognition and Motion to Supplement the Record filed by LBCA are hereby denied. DONE AND ORDERED this 14th day of July 1993, in Palatka, Florida. ST. JOHNS RIVER WATER MANAGEMENT DISTRICT By: JOE E. HILL CHAIRMAN RENDERED this 14th day of July 1993. By: SANDRA L. BERTRAM ASSISTANT DISTRICT CLERK
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: Background Respondent, Florida Rock Industries (FRI or applicant), a Florida corporation, operates a nine hundred and eighty acre sand mine known as the Goldhead Sand Mine (Goldhead) in Clay County, Florida. The mine is located approximately six miles northeast of Keystone Heights and fifty miles southwest of Jacksonville. FRI has operated the mine since 1958. With the exception of eighty acres of land owned by FRI, the remainder of the land on which the mine is located is owned by Carroll-Phillips Investors and has been leased to FRI since 1973. The mine lies within the jurisdictional boundaries of respondent, St. Johns River Water Management District (District), a special taxing district created by the legislature and charged with the responsibility for administering and enforcing permitting programs for consumptive uses of water. FRI is accordingly subject to the District's regulatory authority. As a necessary component of its operation, FRI withdraws approximately 2.09 million gallons per day (MGD) of groundwater from the Floridan Aquifer which is used in the production of sand. This use of water is made pursuant to a consumptive use permit (no. 2-019-0012U) issued to FRI by the District on December 11, 1984, and which allows it to consume 762.85 million gallons per year of groundwater for hydraulic dredging, cleaning and purification of sand at the Goldhead mine. The permit was issued for seven years. In order to continue groundwater withdrawal and use, FRI has applied to the District for a seven-year renewal of its permit with no request for an increase in allocation. That request, which has been identified as application no. 2-019-0012AUR, is the subject of this proceeding. After conducting a review of the application, making site inspections, and performing various studies and analyses, on July 28, 1992, the District, through its staff, gave notice of its intent to approve the application with certain conditions. Thereafter, on August 6, 1992, petitioner, Lake Brooklyn Civic Association, Inc. (petitioner), a nonprofit corporation made up of property owners in adjacent areas of Clay County, filed a petition under Subsection 403.412(5), Florida Statutes, seeking to contest the proposed action. Petitioner is a citizen of the state and has an interest in activities that may injure or harm the state's water resources. Thus, it has standing to bring this action. As twice amended, the petition generally alleged that the consumptive use would (a) cause an unmitigated adverse impact on adjacent land uses, including a significant reduction in water levels in Lake Brooklyn and Spring, Gator Bone, and White Sands Lake, which lie generally to the south and southwest of the mine site, (b) cause a deterioration in water quality, (c) cause economic or environmental harm, and (d) be for purposes other than operating a sand mine. The broad three-pronged test to be used in determining whether the permit should be issued is whether the proposed consumptive use is a reasonable- beneficial use, whether it will interfere with presently existing legal uses of water, and whether it is consistent with the public interest. In addressing this test, the parties have presented extensive expert testimony involving highly technical subject matter. As might be expected, the experts reached different conclusions as to whether the criteria have been met. In resolving these conflicts, the undersigned has accepted the more credible and persuasive evidence, and this accepted testimony is recited in the findings below. The Mining Site Operations The entire mine site is around 7,000 feet east to west, about one mile north to south in a rectangular shape, and lies within the lake region of northeast Florida. The mine's product is silica sand used for concrete and masonry mortar for construction throughout northeast Florida. As such, it produces an economic benefit to the region. The mine is located on one of the few sites in the northeast Florida area with deposits suitable for construction purposes and is the closest sand mine to the Jacksonville market. In 1958, FRI installed three ten-inch diameter production wells in the center of the mine site. One well is 450 feet deep while the other two are 460 feet deep. The 1984 permit authorizes withdrawals of 762.85 million gallons of water per year, an average rate of 2.09 MGD, and a maximum rate of 3.75 MGD. This rate is consistent with the amount of water used at other mines in north Florida and is based on FRI's projected maximum annual use. The use is industrial commercial for sand mining while the source is the Floridan Aquifer, the lowest acceptable water quality source available capable of producing the requested amount of water. Water use withdrawal from the three wells is monitored by in-line flow meters installed in 1991 as a water control and conservation measure. The pumping rate depends on the number of fixtures and valves open in the system at the time of pumping. However, the actual rate of water production cannot be varied at any of the pumps since the wells are connected to "on or off" pumps. The need for water in the dredge pond and processing plant dictates how long FRI will have a pump in operation. Water from the wells is first discharged into a dredge pond, twenty feet deep, which is an approximately 155-acre excavation lake located in the southwest portion of the mine site. In periods of low water, the water is used to float the dredge, which requires some three feet of water to float, and in conjunction with a bulldozer, to wash sand down from the bank toward the dredge. After the dredge sucks up sand and water from the bottom of the pond, this mixture is slurried to an on-site processing plant where more water is added to sort and wash the sand. The end product (silica sand) is then loaded onto trucks which haul the product to the market. After processing, the moisture content of the sand product is only 5 percent. The tailings (unusable waste product) and wash water are then routed by a slurry pipe to settling areas and eventually recirculated through a system of ditches, canals and water control structures back into the dredge pond. No chemicals are used in the operation. Although FRI's contract with the lessor of the property requires it to maintain the dredge pond elevation at a specified elevation, this requirement cannot be fulfilled during drought conditions. The mining operation is a closed system to the extent there is no point source (surface water) discharge from the system. Even so, a significant amount of water loss occurs during the process, mainly through percolation into the ground. Other water loss occurs through evaporation. The receiving water from the site is primarily the surficial aquifer which recharges the downgradient lakes, including Gator Bone, White Sands, and Spring Lakes. Water may also travel through the surficial aquifer into the sinkholes on site and thence to the Floridan Aquifer. However, not all water is lost to sinkholes in the settling area because they are filled with fine materials. This is confirmed by the fact that water returns to the dredge pond. The mining operation has not affected this pattern. The lakes in the region are replenished solely by rainfall, either by direct rain on the lakes or through water seeping through sands. FRI plans to mine approximately thirty additional acres at the Goldhead Site during the next seven years. To this end, it has secured a management and storage of surface waters permit from the District which allows construction of this additional acreage. It also has acquired an industrial waste water discharge permit from the Department of Environmental Regulation. It is expected that within the next two to four years, FRI will abandon the current dredge pond and start a new one on the north side of the property to accommodate mining operations, or in the alternative, extend the current pond to the north. Water conservation A water conservation plan has been submitted by FRI. Measures already implemented include (a) using in-line flow meters to monitor amounts of withdrawal, (b) not pumping for more than seventeen hours per day to prevent exceeding the maximum allotment per day, (c) regularly monitoring withdrawals to ensure allocations as not being exceeded, (d) extending the plant discharge further past the sinkholes in the settling area to maximize return water to the dredge pond, (e) raising water levels in the settling area to facilitate flow back to the dredge pond, (f) during periods of drought using bulldozers instead of water spray to break loose sand formations, (g) curtailing production when further production would cause the plant to exceed allocations, (h) replacing water-cooled bearings in plant machinery with bearings that do not require water, and (i) restricting dredge mobility to allow operation in shallower water. No other water conservation measures are economically, environmentally or technologically feasible. Hydrogeologic characteristics at the mine site The mine site, which is located within the Upper Etonia Creek surface water drainage basin, generally slopes from 200 feet NGVD on the north to 120 feet NGVD on the south, and is underlain, in order, by approximately 10 to 50 feet of sand (known as the surficial aquifer), 200 feet of dense, moist clay (known as the Hawthorn Formation), and then a highly transmissive limestone formation (known as the Floridan Aquifer). The surficial aquifer flows from north to south across the site while water falling on the site primarily moves downgradient through the surficial aquifer. There are five sinkholes on the site, all having predated the mining activities, which may provide a conduit for recharge from the surficial aquifer to the Floridan aquifer. Except where the Hawthorn formation, a confining unit to the Floridan aquifer, is breached, recharge through the Hawthorn formation is very slow because of the dense clays of that formation. Aquifer characteristics within the Floridan aquifer beneath the site and immediately adjacent thereto are relatively uniform. As noted earlier, 5 percent of the water leaves the mine site as moisture in the sand product. The remaining 95 percent of water is immediately recharged on site to the surficial aquifer through various impoundments, and after entering the surficial aquifer, that portion of the water which is not recirculated to the dredge pond for reuse in the mining process moves either vertically into the Hawthorn formation, vertically into the Floridan aquifer through a sinkhole, downgradient through the surficial aquifer to one of the lakes south of the mine, or evaporates. It is noted that notwithstanding the mining operations, the flow in the surficial aquifer system still parallels the topography as it existed prior to mining, and the same saturated thickness within the surficial aquifer exists on site as existed before mining occurred. Hydrogeologic Characteristics of the Region The region in which the mine is located is very high in topographic altitude indicating that it is a groundwater recharge area. Like the mine site, the region has three distinct geologic units underlying the surface, including sands and clayey sands (surficial aquifer), thick clays (Hawthorn formation) and limestones and dolomites (Floridan aquifer). The Hawthorn unit serves as a confining unit or semi-confining unit between the surficial aquifer, or water table, in the upper unit and the Floridan aquifer in the lower unit. When solution channels develop within the limestones in the lower unit, the openings can cause the overlying units to collapse, forming sinkholes. Thus, when the Hawthorn formation is breached by the development of a sinkhole, water can move rapidly through the overlying units to the Floridan aquifer. Many of the lakes within the region exist over collapsed features within the limestone units beneath them and are referred to as sinkhole lakes. The rate of recharge from each lake depends on the rate of leakance into the Floridan aquifer. Some lakes leak fast, others not at all. For example, Lake Brooklyn fluctuates about two feet, Lake Johnson about thirteen feet, and Pebble Lake about thirty feet. Lake Brooklyn, which lies several miles to the southwest of the mine, is the fourth lake in a chain of lakes consisting of Blue Pond, Sand Hill Lake, Lake Magnolia, Lake Brooklyn, Keystone Lake, Lake Geneva, Oldfield Pond, and Half Moon Lake. All of these lakes are in a different surface water drainage sub-basin within the larger Upper Etonia Creek Basin than the mine site. The lakes above Lake Brooklyn in the chain are at higher elevations than Lake Brooklyn, and when rainfall is sufficient, water flows from Blue Pond to Sand Hill Lake, to Lake Magnolia, and then to Lake Brooklyn through Alligator Creek. Direct rainfall and surface water inflows from Alligator Creek represent the most significant sources of water to Lake Brooklyn. Other pertinent lakes in the area are Spring, White Sands and Gator Bone Lakes, which lie almost directly along the mine site's southern boundary and are each less than a mile from the mine's dredge pond. During the period records have been maintained for water levels in Lake Brooklyn, it has fluctuated over a range of slightly more than twenty feet. Although average rainfall within the Upper Etonia Creek Basin is approximately fifty-one inches per year, during the period from 1974 through 1990 the basin experienced a continuing period of below normal rainfall resulting in a cumulative deficit of rainfall for this period of minus seventy-eight inches. Since 1988, the lake region has experienced a severe drought. Because the lakes in the region have risen or fallen in correlation with periods of below normal or above normal rainfall, lake levels have fallen dramatically in recent years. Water levels in Lake Brooklyn began declining in 1974 at the same time the period of below normal rainfall began and continued declining until 1991, a year in which the region experienced above normal rainfall. These low water levels were exacerbated by the cessation of surface water inflows from Alligator Creek in late 1988 which continued until late 1992 when such flows resumed. The cessation of surface water flows into Lake Brooklyn during the period from 1988- 1992 were a direct consequence of the extended period of below normal rainfall in the region. Finally, very little, if any, of the groundwater flowing in the Floridan aquifer beneath Lake Brooklyn flows toward the mine site. Water Quality Impacts Numerous analyses have been conducted to determine water quality of the site, water quality in nearby homeowners' water systems, and water quality impacts of the proposed consumptive use. They include analyses conducted by the District in 1989 and 1992, including sampling of water quality and an analysis of the background levels for certain parameters, and an assessment of data from HRS testing in March 1989 and May 1992. In addition, FRI conducted water quality sampling on site in eight wells, the dredge pond and a settling pond. Finally, petitioner reviewed water quality samples from off-site private water supply wells taken on March 1, 1989, and on July 22, 1992, by unknown persons. As to this latter sampling, petitioner had no knowledge of the protocol used in obtaining the 1989 samples and offered no evidence of reliability of the 1992 data. Thus, the reliability of its assessment is in doubt. None of the water quality samples taken from the mine site indicate a violation of state water quality standards. However, petitioner posits that a chemical reaction is likely occurring at the deeper levels of the dredge pond, possibly causing undissolved iron in sediments to become dissolved, and then traveling in solution through the clays of the Hawthorn formation into transmissive units and finally to off-site homeowners' wells which may be in those units. This theory was predicated on the results of 1989 HRS sampling which revealed some wells near White Sands Lake experienced elevated levels of iron and manganese, and an assumption that a chemical reaction was occurring because herbicides were used in the dredge pond. However, only one application of a herbicide occurred, and that was in 1990, or one year after iron was detected in the off-site homeowners' wells. Petitioner agreed that the 1990 application of herbicide could not have affected the 1989 sampling. It also agreed that these reactions were less likely to be occurring in a pond with water flowing through it. In this case, water is circulated through the dredge pond by being pumped into it, pumped out of it, and allowed to flow back into the pond. FRI determined that no state water quality standards were exceeded for iron, manganese, zinc, turbidity, total dissolved solids, chloride and nitrate in the surficial aquifer and Hawthorn formations at the site. The wells used for monitoring water quality were installed and sampled using standard quality assurance techniques. Water quality from the surficial aquifer was emphasized because if iron or manganese were present in the water, it would most likely be detected in wells in the surficial aquifer because they are detected in wells immediately downgradient of the source. If the chemical reaction is occurring, water leaving the dredge pond is contaminated, and such water will follow the path of least resistance by going either to the Hawthorn formation or the surficial aquifer. Because of the geologic properties of the Hawthorn, this path is the surficial aquifer. At least 70,000 gallons per day enter the surficial aquifer from the bottom of the dredge pond. Since contaminated water would receive water quality treatment by absorption of the Hawthorn but not in the surficial, water in the surficial aquifer represents the worst case scenario as to the possible presence of contaminated water. The chemical reactions which petitioner believes may be occurring in the deeper portions of the dredge pond require the presence of an acidic environment and reduced oxygen levels in the water. FRI's water quality testing indicates that water in the dredge pond is not acidic, but rather is neutral. Therefore, any reaction which might be occurring could not be on a large enough scale to affect water quality. Moreover, even if the reactions were occurring, it was established that the clays in the Hawthorn formation would absorb iron, and such absorption would not take place in the surficial aquifer. Therefore, it is found that there would be no adverse impact to groundwater including the surficial aquifer and that water quality standards will be met. Although petitioner presented evidence that in 1989 HRS testing of 12 out of 212 homeowners south of the mine site indicated that three homeowners had iron concentrations in excess of state drinking standards and two had manganese concentrations in excess of state drinking water standards, this is insufficient to prove that the mining operation has an adverse impact on water quality. To begin with, some of the wells sampled were thirty to fifty years old even though the life expectancy of a well is fifteen to twenty years. Some were constructed of galvanized steel pipe, and those wells also indicated high turbidity levels. High turbidity levels are caused by a number of unrelated factors and will result in increased iron levels that are not representative of the quality of the groundwater in the formation, but rather of the iron-laden sediments in the formation, or from the casing material. With the exception of one well (the Sutton well), the water from the homeowners' wells did not exceed background water quality for iron and manganese. The elevated iron and manganese concentrations in the Sutton well are caused by a number of factors other than the mine. Then, too, a proper sampling technique may not have been followed during the 1989 sampling event thus rendering the results unreliable. Finally, properly constructed monitoring wells should be used to assess the quality of the groundwaters, and the wells sampled in 1989 and 1992 were not of that type. The Mine's Impact on Water Levels Perhaps the issue of primary concern to members of petitioner's organization is whether the mining operations have contributed to the decline in water levels of nearby lakes, including Lake Brooklyn. This is because of serious declines in the levels of those water bodies over the past years, and a concomitant decrease in the value of homes which surround the lakes. In an effort to resolve this and other water level issues, the parties made numerous studies of the current and anticipated water level impacts from the site. This data collection effort was far more extensive than is normally conducted for a mine of this size. They included aquifer performance tests by FRI and the District, steady state and transient computer modeling of impacts on the Floridan and surficial aquifers by FRI, an analysis of correlations of pumping and water level changes in lakes and aquifers by FRI and petitioner, photolinear and fracture trace analyses of structural conditions by FRI and petitioner, a stratigraphic analysis of a geologic core retrieved from the site by FRI, installation of deep and shallow wells for groundwater monitoring by FRI, groundwater flow mapping by FRI, review of literature by all parties, review and analysis of rainfall data by all parties, analysis of evaporation data by the District and petitioner, and an analysis of geophysical logs from wells by FRI and the District. Aquifer performance tests Aquifer performance tests, which enable hydrologists to reach conclusions regarding the characteristics of the aquifers tested, were conducted in January 1989 by the District and June 1991 by FRI. In a typical pump test, an aquifer production well pumps at a constant rate, while water levels are monitored in observation wells at specified distances from the pumping well. In this case, the tests measured effects of pumping from the mine production wells for periods ranging from 78 hours to 108 hours at approximately twice the average rate of 2.09 MGD. The zone of influence of pumping was measured at wells placed at the property boundaries, at Gold Head State Park, east of the mine, as well as wells to the south of the mine for the 1989 tests. During the 1989 tests, lake levels for Lake Brooklyn and Gator Bone, White Sands and Spring Lakes were recorded. The effects of pumping were approximately equal for wells spaced approximately equal distances along the east, south and west. Thus, for purposes of analysis, the Floridan aquifer was considered isotropic and homogeneous. This is consistent with assumptions commonly made by geologists in Florida. Computer models were calibrated with actual results of these tests to account for variations caused by this assumption. The District has concluded, and the undersigned so finds, that no changes in the levels of the lakes are attributable to pumping. Further, the aquifer itself will not be harmed by the use of the amount of water requested in the application. The tests indicate the maximum amount of drawdown in the Floridan aquifer from pumping at twice the average rate is 0.1 to 0.6 foot in neighboring wells. Effects of actual pumping will be approximately one-half the test observed amounts on an average pumping day. For example, based on the 1989 test results, drawdowns in the Floridan aquifer at the boundary of the FRI property during an average day of pumpage should not exceed 0.2 to 0.3 feet while drawdowns beneath Spring, White Sands and Gator Bone Lakes to the south of the mine should be less than 0.2 feet. The tests provide actual measurements of the effects of pumping. Indeed, all three lakes were declining before the 1989 test began and continued to decline after the test was ended. However, the rate of decline during the seventy-eight hours of the test was not distinguishable from declines which occurred before or after the test. Computer modeling As a supplement to the aquifer performance tests, FRI performed computer modeling to determine effects of the water withdrawal and use on the Floridan and surficial aquifers. These models are used by hydrologists to predict impacts associated with a particular source of stress, such as pumpage, to an aquifer and, in this case, occurred in three phases. The first was an impact model which determined the drawdown in the Floridan aquifer. The second occurred as a result of questions raised by residents of the sand mine area and included a "steady state" model simulation of impacts of the Floridan and surficial aquifers. The third occurred as a result of questions raised by petitioner and included new data along with both a "transient state" and "steady state" simulation. All three phases of modeling were consistent in finding that the effects of pumping are non-existent or negligible, that is, a predicted drawdown in various locations of the Floridan aquifer of from less than 0.1 to 0.3 feet on an average pumping day, and they corroborated the drawdowns observed during both the 1989 and 1991 aquifer performance tests. Petitioner's witness Dr. Stewart criticized FRI's 1992 "steady state" computer modeling on the grounds FRI had insufficient data to conduct the modeling, the constant head boundaries were set too close to the pumping, a transient model should have been run, and the modelers assumed that the Floridan aquifer is isotropic and homogeneous. However, Dr. Stewart failed to review or consider (a) any technical data or information gathered since September 10, 1992, (b) the 1991 transient model, (c) the December 1992 transient model, (d) the computer disc for the July 1992 steady state model, (e) the December 1992 steady state model, (f) the December 1992 calibration, (g) the basis for setting the constant head boundaries, or (h) the data from the 1989 and 1991 pump tests. All of this data was part of the evidence FRI's experts used in formulating their opinions. Dr. Stewart agreed that he could not form any conclusions on this data and that the Floridan aquifer is rarely completely homogeneous and isotropic, but that he and other modelers regularly make that assumption. The modeling was calibrated to replicate actual subsurface and pumping conditions. Maximum drawdown in the Floridan aquifer under normal pumping conditions is modeled to be 0.1 to 0.2 feet beneath White Sands Lake. This is drawdown with no replacement, although there will be leakance back to the Floridan aquifer through sinkholes on the site and surcharge to Gator Bone, White Sands and Spring Lakes through the surficial aquifer. The impact to the Floridan is minor compared to normal water level fluctuations in that aquifer of 3 to 5 feet per year. In fact, barometric pressure changes can cause water level changes of up to one foot per week. Lake levels Because many of the lakes in the area leak downward, water levels in the lakes could be affected by the changes in levels in the Floridan aquifer. Indeed, for lakes connected to the Floridan aquifer, changes in the level of the potentiometric surface (or pressure) in the Floridan aquifer can have an impact on the level of the lakes. However, a decrease in lake levels will be less than that of the decrease in the Floridan aquifer, depending on the rate of leakance. Consequently, even if Lake Brooklyn and Gator Bone, White Sands or Spring Lakes do leak to the Floridan aquifer, the amount of decline in lake levels attributable to pumping at the mine will be less than the 0.1 to 0.2 foot modeled by FRI. This drawdown effect will not accumulate over time, but rather will remain constant after reaching steady state conditions. Even if levels in Gator Bone, White Sands and Spring Lakes are affected by drawdowns in the Floridan aquifer, that effect will be more than offset by surcharge to the surficial and Floridan aquifers from the dredge pond. The net effect to the lakes would be either positive or immeasurable. This is confirmed by the computer modeling results. Lake stage and precipitation data for Spring, White Sands and Gator Bone Lakes indicates that these lakes, like other lakes in the region, rise and fall in correlation with precipitation patterns. For example, in 1991, a year with above normal rainfall, Spring Lake rose 4.1 feet in elevation, White Sands Lake 2.9 feet in elevation, and Gator Bone Lake rose 3.5 feet in elevation. Similarly, water levels were monitored before, during and after the 1989 aquifer performance test in a portion of Lake Brooklyn known as Brooklyn Bay. Because of low rainfall, Brooklyn Bay was separated from the main body of Lake Brooklyn for at least eighteen to twenty-four months before and during the 1989 aquifer performance test. The lake had been in the midst of a long term decline both before and after the test, and the rate and character of declines during the period of pumping were not distinguishable from the declines occurring before or after the test. It is accordingly found that the impacts on water levels in Lake Brooklyn, if any, as a result of pumping from the Floridan aquifer are immeasurable. According to petitioner's witness Boyes, activities at the mine have an influence on water levels in Gator Bone, White Sands and Spring Lakes by "increasing the rate of decline". However, the witness could not quantify the degree of impact but stated the impacts during the 1989 aquifer performance tests were a decline of .03, .03 and less than .03 foot, respectively, for each lake. The witness also opined that, based on District staff guage readings during the 1989 aquifer performance testing, pumping at the mine resulted in a .04 foot decline in lake level for Lake Brooklyn during the 1989 testing period. This decline had a net result of .8 acre decrease in the previously 600 acre plus Lake Brooklyn. By comparison, the drought caused a decline of 162 acres in 1989 and an additional 158 acres in 1990. It is noted that the decline in each lake would be less during average pumping conditions, or about one-half of the .04 foot decline, since average pumping is one-half of the aquifer performance test pump rate. Finally, petitioner's witness Dr. Stewart opined that there is insufficient data to determine whether any impacts to lake levels are occurring. It is found, however, that these drawdowns are less than the .1 to .2 foot modeled by FRI and should have no significant adverse impacts on water levels. Preferential flow theory Petitioner presented evidence of a purported correlation between pumping at the mine and water levels in a Floridan aquifer well located on the southwest side of Lake Brooklyn, 4.3 miles from the mine, and lake levels in Brooklyn Bay, 3 miles from the mine. According to petitioner, this serves as proof of a "preferential flow pattern" in the Floridan from Lake Brooklyn to the mine, and that this preferential flow results in a .04 to .05 foot drawdown in the Floridan aquifer at Lake Brooklyn. However, this correlation is deemed to be incorrect for several reasons. First, if a true correlation existed, recovery from pumping effects would occur after pumping ceased, but the Lake Brooklyn well showed recovery in the Floridan aquifer prior to cessation of pumping, and did not recover when pumping stopped at the end of the 1989 aquifer performance testing. Second, if the premise is correct, impacts from pumping would occur in wells closer to the pumping earlier than in wells farther away, but the Lake Brooklyn well, 4.3 miles from pumping, showed drawdown began before that of the Goldhead well, only 1,000 feet from pumping. Third, levels for the Lake Brooklyn well should have declined during both the 1989 and 1991 aquifer performance tests but the levels rose during the 1991 tests. As to the water level changes in the well during the 1989 test, witness Boyes believed these may reflect declines due to hydrologic conditions rather than the pump test. Fourth, if a true correlation existed, impacts would be experienced following the same hydrographic pattern as pumping, but the Lake Brooklyn well's hydrographics did not correlate to the pumping schedule at all times of the year. It should also be noted that at least two other large scale water users are withdrawing water from wells within 1.25 miles from the Lake Brooklyn well and may affect that well's water levels. Further, the variations in the well may be explained by many other variables, such as barometric pressure changes, diurnal fluctuations in water levels, rainfall, and pumping from closer wells. Finally, Brooklyn Bay is now physically separated from Lake Brooklyn, and it was improper for petitioner to rely on lake level information from Brooklyn Bay to support its theory regarding Lake Brooklyn. To further support its hypothesis that a preferential flow path exists between the mine and Lake Brooklyn, petitioner utilized a "photo linear analysis" or "fracture trace analysis", which is based on an interpretation of surface topographic features to determine the presence of subsurface hydrogeologic features such as solution channels in the limestones of the Floridan aquifer. However, without extensive subsurface testing, which is not present here, such analyses are only interpretative to determine what, if any, subsurface features are present and their hydrogeologic effect. It is noted that subsurface fractures are present less than 50 percent of the time, and if present, the features may be hydrologic barriers as well as preferential flow paths. According to witness Boyes, a photolinear feature (fracture) exists from Lake Brooklyn through Spring Lake and across the mine property to Goldhead State Park. If such a feature did exist, however, the drawdown during the aquifer performance tests and other pumping would be greater adjacent to Spring Lake than adjacent to Lake Brooklyn. This was not observed. Moreover, petitioner's witness Dr. Stewart thought the photolinear was only inferred and had a lower degree of confidence that it exists. FRI's witness Fountain established that elongated surface features are more likely to demonstrate linear subsurface features. Both witness Boyes and Dr. Stewart agreed with this conclusion. That being the case, the postulated Lake Brooklyn-mine photolinear is not demonstrated, and continuation of the elongated axis of Lake Brooklyn and Brooklyn Bay would bypass the mine site altogether. Because no investigations have been conducted to demonstrate that these postulated photolinear features exist, and the more reliable results of the aquifer performance tests indicate otherwise, the preferential flow path theory is deemed at best to be highly speculative. If the Lake Brooklyn-mine photolinear feature offered a preferential flow path as opined by witness Boyes, the resulting drawdown would be elongated with a zone of influence extending from the mine westward toward Lake Brooklyn. Therefore, areas closer but not on the feature would experience less drawdown than areas farther away which are on the feature, the zone of influence would extend from the mine's wells through Spring Lake toward Lake Brooklyn causing declined water levels along the feature, and areas closer to the pumping wells, such as Spring Lake, would experience a greater decline than areas farther away, such as Lake Brooklyn. However, evidence offered by petitioner shows that the water levels between Lake Brooklyn and the mine are actually higher than in surrounding areas. Finally, even if petitioner's preferential flow path theory were true, there is no evidence that the pumping from the mine is resulting in significant and adverse impacts as required by District rules. Therefore, it is found that the sand mine does not cause significant and adverse impacts on the water levels in the Floridan aquifer or on the water levels of Lake Brooklyn or Gator Bone, White Sands or Spring Lakes. Rather, the lake levels in each of the four lakes in issue here are directly or indirectly a function of rainfall. Intermediate and surficial aquifers Whether an intermediate aquifer is present beneath the mine site is subject to dispute. All parties agree that, on a regional scale, the Hawthorn formation contains some discontinuous water-bearing lenses that in some places produce water in quantities sufficient for household use. The lenses occur in carbonate deposits in the formation, although not all carbonate deposits or all water bearing units will necessarily transmit water. The evidence is less than persuasive that the Hawthorne formation contains carbonate units which are present on the sand mine site as transmissive beds. This finding is based on FRI's review of on-site core boring information and other data from the site. In addition, this finding is corrorborated by District witness Lee, who concluded that water from the site is not discharging into the Hawthorn, but rather into the surficial aquifer. This is because clays comprising the Hawthorn have low permeability, causing water to flow laterally through the surficial aquifer rather than into the Hawthorn. With respect to impacts to the surficial aquifer, FRI presented evidence that during mining operations, the surficial aquifer will be surcharged by up to five feet. When mining operations cease, water levels will return to natural conditions. This evidence was not contradicted. Impacts on Property Values and Recreation Testimony regarding the property values for lake front properties on Lake Brooklyn and Gator Bone, White Sands and Spring Lakes was offered by petitioner's witness Price. He established that values have declined since mid- 1989 as a result of a loss of recreational value suffered as water levels have receded. However, witness Price stated that he would not expect a 0.1 foot drop in lake levels to negatively affect property values. Since the declines predicted by petitioner are far less than a 0.1 foot drop, it is apparent that FRI's water use will not result in harm to property values in the area. Similarly, while it is true that declining water levels have impaired recreational uses of Lake Brooklyn and Gator Bone, White Sands and Spring Lakes, FRI's water use cannot be blamed for such impairment. Environmental Impacts The anticipated impacts of the water use on the wetlands and wildlife resources of the area were addressed by FRI witnesses Peacock and Lowe. According to Peacock, who analyzed the wetland vegetation, the dominant species and their adaptions, the wildlife resources and their adaptions, and the general ecology of the area, the water levels in the adjacent lakes have historically fluctuated greatly, and wildlife that use the lakes have adapted to these fluctuations. His opinion that the mine's water use will not have any significant adverse impact on the environment of Lake Brooklyn and Gator Bone, Spring or White Sands Lakes is hereby accepted. Based upon witness Lowe's inspection of the three downgradient lakes, his past knowledge of Lake Brooklyn, the aquifer performance tests, and Dr. Lee's conclusion that the maximum drawdown in the lakes would be 0.1 foot, Lowe opined that the proposed water withdrawal will not cause environmental harm. In addition, such a drawdown will not adversely affect off-site vegetation or cause unmitigated adverse impacts on adjacent wetlands or other types of vegetation. These conclusions were not contradicted and are hereby accepted. Compliance with rule criteria To obtain a consumptive use permit, an applicant must give "reasonable assurance" that the proposed water use is a reasonable beneficial use, will not interfere with any presently existing legal use of water, and is consistent with the public interest. These broad criteria are further explained by criteria enunciated in Rule 40C-2.301(3)-(6), Florida Administrative Code, and sections 9.0 et seq. and 10.0 et seq. of the Applicant's Handbook adopted by reference in Chapter 40C-2, Florida Administrative Code. Findings as to whether these criteria have been satisfied are set forth below. To obtain a renewal of a consumptive use permit, an applicant must first give reasonable assurance that the proposed use of water is a "reasonable beneficial use". For a use to be considered reasonable beneficial, the criteria enumerated in Rule 40C-2.301(4) and (5), Florida Administrative Code, must be satisfied. First, paragraph (4)(a) of the rule and section 10.3(a) of the handbook require that the water use must be in such quantity as is necessary for economic and efficient utilization, and the quantity requested must be within acceptable standards for the designated use. The evidence shows that FRI has used a reasonably low amount of water necessary to continue operations at the mine, it has implemented some water conservation methods and tried or considered others that proved to be inefficient or not economically feasible, and the requested amount of water is within acceptable standards for sand mines operating within the District. Then, too, some ninety-five percent of the water pumped from the wells is recirculated for reuse in the mining process or is recharged back into the surficial and Floridan aquifers on site. Finally, there is no surface discharge of water outside the mining site. Accordingly, it is found that this criterion has been satisfied. Paragraph (4)(b) of the rule and section 10.3(b) of the handbook require that the proposed use be for a purpose that is both reasonable and consistent with the public interest. The proposed use of the water is to produce sand used in construction materials. This is a reasonable use of water and results in an economic benefit to the region by producing a valuable product. Accordingly, it is found that the use is both reasonable and consistent with the public interest. All parties have stipulated that the Floridan aquifer is capable of producing the requested amounts of water. This satisfies paragraph (4)(c) of the rule and section 10.3(c) of the handbook which impose this requirement. The next criterion, paragraph (4)(d), as amplified by section 10.3(d) of the handbook, requires that "the environmental or economic harm caused by the consumptive use must be reduced to an acceptable amount." The evidence shows that during mine operations, the surficial aquifer is being surcharged by up to five feet. When they cease, the water levels return to natural conditions. The maximum drawdown anticipated in the Floridan aquifer at the property boundary was 0.3 feet and less than or equal to 0.1 feet for most of the area outside the mine site. At most, this equates to a maximum lake level decline of 0.04 feet at Lake Brooklyn, 0.03 feet at Gator Bone and White Sands Lakes, and less than 0.03 feet at Spring Lake. Thus, FRI's usage of water has had, and will have in the future, little, if any, immediate or cumulative impact on the levels of the area lakes. Further, the more persuasive evidence supports a finding that these lowered lake levels or aquifer levels will not result in environmental or economic harm to the area. In addition, the District has proposed to incorporate into the permit a condition that FRI implement a detailed monitoring plan which will detect any overpumping causing lake level changes and a concomitant adverse impact to off-site land uses. Therefore, this criterion has been satisfied. Paragraph (4)(e) and section 10.3(e) require the applicant to implement "all available water conservation measures" unless the applicant "demonstrates that implementation is not economically, environmentally or technologically feasible." The rule goes on to provide that satisfaction of this criterion "may be demonstrated by implementation of an approved water conservation plan as required in section 12.0, Applicant's Handbook: Consumptive Uses of Water." Because FRI's water conservation plan insures that water will be used efficiently, as required by section 12.3.4.1. of the handbook, this criterion has been met. The next paragraph provides that "(w)hen reclaimed water is readily available it must be used in place of higher quality water sources unless the applicant demonstrates that its use is either not economically, environmentally or technologi-cally feasible." Since the unrebutted testimony establishes that reclaimed water is not readily available to the mine site, it is found that paragraph (4)(f) has been satisfied. Paragraph (4)(g) of the rule and section 10.3(f) of the handbook generally require that the lowest acceptable quality water source be used. Since the evidence shows that the Floridan aquifer is the lowest acceptable quality water source, this requirement has been met. Paragraphs (4)(h) and (i) provide that the consumptive use "should not cause significant saline water intrusion or further aggravate currently existing saline water intrusion problems" nor "cause or contribute to flood damage." The parties have stipulated that these requirements are not in dispute. The next paragraph provides that the "water quality of the source of the water should not be seriously harmed by the consumptive use." The uncontradicted evidence shows that the source of the water for the proposed use will not be seriously harmed from either saltwater intrusion or discharges to the Floridan aquifer. Paragraph (4)(j) and section 10.3(g) have accordingly been met. Paragraph (4)(k) and section 10.3(k) require that the water quality of the receiving body of water "not be seriously harmed" by the consumptive use. In this case, there is no surface water discharge from the mine site. Thus, the only relevant inquiry here is whether the receiving water (surficial aquifer) will be "seriously harmed" by the consumptive use. To determine compliance with this criterion, the District compared water quality samples from the mine site and surrounding areas with the DER monitoring network to ascertain whether state water quality numerical standards and natural background levels were exceeded. The relevant standards are found in Rule 17-520.420, Florida Administrative Code. Monitoring data from eight wells and from the dredge pond indicate there are no water quality violations resulting from the sand mine operations. Petitioner has contended that water from the dredge pond provides a significant source of water to an intermediate aquifer, which would also be a receiving body of water. However, the evidence shows that any contaminants resulting from the dredge pond flowing into an intermediate aquifer will also be contained in the surficial aquifer. The clays of the Hawthorn formation would absorb and filter out iron and manganese as they traveled to a water transmissive zone. Therefore, the concentrations sampled in the suficial aquifer downgradient from the dredge pond represent the highest concentrations. Since the concentrations in the surficial aquifer do not violate water quality standards, the same finding as to concentrations in the intermediate aquifer can be made. Further, the rule criteria require consideration of the future water use's effect on water quality, and if the intermediate aquifer is in fact a receiving water as contended by petitioner, the reactions which could cause water quality violations are presently occurring. There is no reason to believe they would cease if the mine ceases operation, and the mining operation adds oxygen to the water, which reduces the possibility of the reaction described. Therefore, this criterion has been satisfied. The parties have stipulated that the requirements of paragraph (4)(l) have been fulfilled. Finally, rule 40C-2.301(5)(a) provides that a proposed consumptive use will not meet the criteria for issuance of a permit if such proposed water use will significantly cause saline water encroachment or otherwise cause water flows or levels to fall below certain minimum limits set forth in the rule. The evidence shows that, to the extent these criteria are applicable and in dispute, they have been satisfied. Miscellaneous The contention has been made that insufficient site-specific information was submitted by the applicant to determine the effects of the proposed use of water at the sand mine. In this regard, the evidence shows that FRI consultants installed monitoring wells, performed core borings, and took soil samples at the site. The geology of the site was verified by core boring, review of geologic logs and drilling wells. Slug tests were performed to measure the hydraulic conductivity of the material in which the monitor wells were set, and a step drawdown analysis was performed to measure hydraulic conductivity. A number of monitoring wells to measure water levels data were installed before and after running the 1991 aquifer performance tests, and groundwater modeling in both the transient and steady state modes were run using data that was collected in the field. In addition, water quality samples were collected to evaluate a water budget for the dredge pond, and FRI conducted an assessment of the environmental impacts to the wetland and wildlife resources of the area lakes, including White Sands, Spring and Gator Bone Lakes. Besides this submission and analysis, the District reviewed United States Geological Survey (USGS) topographic maps, potentiometric maps and aerial photographs of the area, water levels of the surrounding lakes, potentiometric surfaces in Floridan and intermediate aquifer wells, geophysical logs for wells, rainfall records, the core generated by FRI consultants, and scientific literature relied upon in making consumptive use permitting assessments. It also monitored the 1991 aquifer performance test and reviewed the resultant model. Before and after submission of the application, the District conducted aquifer performance testing at the site and evaluated the 1991 aquifer performance test conducted by FRI consultants. Finally, the District assessed water quality impacts of the sand mine in 1989 and in the present by site visit, sampling of the Floridan production well and dredge pond, and reviewing sampling data from both monitor wells and homeowner wells. It also reviewed information on water quality data gathered from other sand mines and applied data from the DER background monitoring network. Therefore, the contention that insufficient site-specific information was submitted and considered is rejected. Petitioner has offered into evidence petitioner's exhibits 61, 64, 65, 71, 75, 76, 78-80, 82 and 83. A ruling on the admissibility of the exhibits was reserved. The exhibits, which are based on data collected by the District and the USGS, are hydrographs showing water levels from lakes and monitoring wells during so-called "normal mine operations" on selected dates in 1988, 1989 and 1991. Although FRI was given copies of the exhibits ten days prior to hearing, it was not informed of the source of the data until final hearing. As it turned out, petitioner's witness had reviewed records over an extensive period of time and selected two or three days out of that time period as being representative of "normal" conditions. However, FRI established that, when longer periods of time were reviewed, the correlations alleged to exist by the graphs did not in fact exist and thus they did not represent normal conditions. Attorney's fees and costs FRI has requested an award of attorney's fees and costs on the theories petitioner interposed various papers and brought and participated in this action for "an improper purpose" within the meaning of Subsections 120.57(1)(b)5. and 120.59(6), Florida Statutes. In addition, petitioner has filed a motion for sanctions on the ground four motions filed by FRI were filed for an improper purpose within the meaning of Subsection 120.57(1)(b)5., Florida Statutes. It may be inferred from the totality of the evidence that petitioner did not intend to participate in this proceeding for an improper purpose. Likewise, the same inference may be made with respect to the four motions filed by FRI. Therefore, fees and costs (sanctions) are not warranted for either party.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that a final order be entered by the District granting application number 2-019-0012AUR as proposed by the District in its notice of intent to approve the application issued on August 6, 1992.

The Issue The issues in this case are whether penalties should be imposed and investigative costs and expenses assessed against Respondent for water supply system violations; and, if so, the amount of the penalties and assessments.
Findings Of Fact Respondent, Premier Construction Group, Inc., owns and operates a water treatment plant and associated piping in a commercial building it owns and leases at 2315 Highway 41 North in Inverness. The water treatment plant consists of a 500- gallon tank that holds groundwater pumped from a well. The water in the tank is treated with chlorine and distributed throughout the building for potable water use. The water system serves 25 or more people daily for at least 60 days a year and serves the same people for over six months a year. Respondent owned and operated the water system for 18 and a half years with no violations. Respondent hired a licensed water treatment plant operator to monitor and ensure compliance with applicable DEP rules. In August 2009, Respondent’s licensed operator increased his price substantially. Rick Suggs, as Respondent’s owner and president, disputed the increase and asked the licensed operator to reconsider. Family obligations then required Mr. Suggs to travel to South Carolina for an extended period of time, and Respondent did not attend to the matter further. By the end of August 2009, Respondent’s licensed operator notified DEP that he would no longer be servicing Respondent’s water system as of the end of the month. On August 24, 2009, DEP mailed Respondent a letter relaying this information and putting Respondent on notice that a new licensed operator would have to be hired for September. Notwithstanding Respondent’s communications with its licensed operator and DEP in August, Respondent did not hire a new licensed operator. Mr. Suggs testified that Respondent did not know its licensed operator actually quit until later in September. When this was brought to Mr. Suggs’ attention, he instructed his office manager to hire a replacement. Respondent thought the matter was resolved, but the supposed replacement did not proceed with the work. While Respondent was without a licensed operator, the residual chlorine in the system dropped to zero when tested by DEP on September 17, 24, and 30 and on October 7 and 13, 2009. As a result, the water system did not comply with disinfection requirements during September and October 2009. Respondent did not notify DEP of its failure to comply with disinfection requirements in September and October 2009. No monthly operation reports were submitted to DEP for Respondent’s water system for September or October 2009. No bacteriological samples were collected from Respondent’s water system for the months of September and October 2009. Respondent did not notify DEP of its failure to collect bacteriological samples in September and October 2009. While without a licensed operator, Respondent did not provide public notification of its failure to collect bacteriological samples in September and October 2009. Well into October 2009, Respondent became aware that the supposed replacement licensed operator was not doing work for Respondent. Mr. Suggs hired a replacement licensed operator named Mike Watson, who began servicing Respondent’s water system on November 17, 2009. Public notification of Respondent’s failure to collect bacteriological samples in September and October 2009 was given on November 25, 2009. On December 11, 2009, Respondent submitted a completed DEP Form 62-555.900(22), Certification of Delivery of Public Notice, as to its failure to notify the public of its failure to collect bacteriological samples in September and October 2009. By not having a licensed operator in September and October 2009, Respondent saved $332. By not having bacteriological samples collected and tested in September and October 2009, Respondent saved $60. There was evidence that DEP spent approximately $678 investigating and enforcing the violations. More may have been spent, but no evidence of any additional costs or expenses was presented. There was no evidence of any other water treatment violations by Respondent after October 2009. Although there was a potential that the violations could have posed a health threat, there was no evidence that the public’s health actually was threatened by Respondent’s violations. The water system was tested on November 18, 2009, and did not have any coliform bacteria. The NOV includes corrective actions (essentially coming into and staying in compliance), which Respondent already has taken. The NOV requests that penalties be paid within 30 days by cashier’s check or money order made payable to the “State of Florida Department of Environmental Protection” and including the notations OGC File No. 09-3847-09-PW and “Ecosystem Management and Restoration Trust Fund” to be mailed to DEP’s Southwest District office at 13051 North Telecom Parkway, Temple Terrace, Florida 33637. Respondent believes the penalties sought by DEP in this case are excessive. Mr. Suggs cited Respondent’s clean record for 18 and a half years, his personal and financial difficulties during the two months when the violations occurred, and his responsiveness in correcting violations beginning in November 2009. Mr. Suggs testified that, during mediation, DEP informed him that the penalties could have totaled $115,000 if an unexplained “matrix” had been used to calculate the penalties. Mr. Suggs thought $115,000 was “ludicrous.” Mr. Suggs also requests that the lesser penalties sought in the NOV be further reduced, especially considering that Respondent paid a lawyer $2,800 for representation earlier in the proceeding, until the lawyer withdrew from the case.
The Issue The issues in this case are whether International Paper Company (IP) is entitled to National Pollutant Discharge Elimination System (NPDES) Permit No. FL0002526 issued by Department of Environmental Protection (Department) and whether the Department should approve Consent Order No. 08-0358, for the operation of IP’s paper mill in Cantonment, Escambia County, Florida.
Findings Of Fact The Department is the state agency authorized under Chapter 403, Florida Statutes (2008), to regulate discharges of industrial wastewater to waters of the state. Under a delegation from the United States Environmental Protection Agency, the Department administers the NPDES permitting program in Florida. IP owns and operates the integrated bleached kraft paper mill in Cantonment. FOPB is a non-profit Alabama corporation established in 1988 whose members are interested in protecting the water quality and natural resources of Perdido Bay. FOPB has approximately 450 members. About 90 percent of the members own property adjacent to Perdido Bay. James Lane is the president of FOPB. Jacqueline Lane and James Lane live on property adjacent to Perdido Bay. The mill's wastewater effluent is discharged into Elevenmile Creek, which is a tributary of Perdido Bay. Perdido Bay is approximately 28 square miles in area. U.S. Highway 90 crosses the Bay, going east and west, and forms the boundary between what is often referred to as the "Upper Bay" and "Lower Bay." The Bay is relatively shallow, especially in the Upper Bay, ranging in depth between five and ten feet. At the north end of Perdido Bay is a large tract of land owned by IP, known as the Rainwater Tract. The northern part of the tract is primarily fresh water wetlands. The southern part is a tidally-affected marsh. The natural features and hydrology of the fresh water wetlands have been substantially altered by agriculture, silviculture, clearing, ditching, and draining. Tee Lake and Wicker Lake are small lakes (approximately 50 acres in total surface area) within the tidal marsh of the Rainwater Tract. Depending on the tides, the lakes can be as shallow as one foot, or several feet deep. A channel through the marsh allows boaters to gain access to the lakes from Perdido Bay. Florida Pulp and Paper Company first began operating the Cantonment paper mill in 1941. St. Regis Paper Company acquired the mill in 1946. In 1984, Champion International Corporation (Champion) acquired the mill. Champion changed the product mix in 1986 from unbleached packaging paper to bleached products such as printing and writing grades of paper. The mill is integrated, meaning that it brings in logs and wood chips, makes pulp, and produces paper. The wood is chemically treated in cookers called digesters to separate the cellulose from the lignin in the wood because only the cellulose is used to make paper. Then the "brown stock" from the digesters goes through the oxygen delignification process, is mixed with water, and is pumped to paper machines that make the paper products. In 1989, the Department and Champion signed a Consent Order to address water quality violations in Elevenmile Creek. Pursuant to the Consent Order, Champion commissioned a comprehensive study of the Perdido Bay system that was undertaken by a team of scientists led by Dr. Robert Livingston, an aquatic ecologist and professor at Florida State University. The initial three-year study by Dr. Livingston's team of scientists was followed by a series of related scientific studies (“the Livingston studies"). Champion was granted variances from the water quality standards in Elevenmile Creek for iron, specific conductance, zinc, biological integrity, un-ionized ammonia, and dissolved oxygen (DO). In 2001, IP and Champion merged and Champion’s industrial wastewater permit and related authorizations were transferred to IP. In 2002, IP submitted a permit application to upgrade its wastewater treatment plant (WWTP) and relocate its discharge. The WWTP upgrades consist of converting to a modified activated sludge treatment process, increasing aeration, constructing storm surge ponds, and adding a process for pH adjustment. The new WWTP would have an average daily effluent discharge of 23.8 million gallons per day (mgd). IP proposes to convey the treated effluent by pipeline 10.7 miles to the Rainwater Tract, where the effluent would be distributed over the wetlands as it flows to lower Elevenmile Creek and upper Perdido Bay. IP's primary objective in upgrading the WWTP was to reduce the nitrogen and phosphorus in the mill's effluent discharge. The upgrades are designed to reduce un-ionized ammonia, total soluble nitrogen, and phosphorus. They are also expected to achieve a reduction of biological oxygen demand (BOD) and TSS. IP plans to obtain up to 5 mgd of treated municipal wastewater from a new treatment facility planned by the Emerald Coast Utility Authority (ECUA), which would be used in the paper production process and would reduce the need for groundwater withdrawals by IP for this purpose. The treated wastewater would enter the WWTP, along with other process wastewater and become part of the effluent conveyed through the pipeline to the wetland tract. The effluent limits required by the proposed permit include technology-based effluent limits (TBELs) that apply to the entire pulp and paper industry. TBELs are predominantly production-based, limiting the amount of pollutants that may be discharged for each ton of product that is produced. The proposed permit also imposes water quality-based effluent limits (WQBELs) that are specific to the Cantonment mill and the waters affected by its effluent discharge. The WQBELs for the mill are necessary for certain constituents of the mill's effluent because the TBELs, alone, would not be sufficient to prevent water quality criteria in the receiving waters from being violated. The Livingston studies represent perhaps the most complete scientific evaluation ever made of a coastal ecosystem. Dr. Livingston developed an extensive biological and chemical history of Perdido Bay and then evaluated the nutrient loadings from Elevenmile Creek over a 12-year period to correlate mill loadings with the biological health of the Bay. The Livingston studies confirmed that when nutrient loadings from the mill were high, they caused toxic algae blooms and reduced biological productivity in Perdido Bay. Some of the adverse effects attributable to the mill effluent were most acute in the area of the Bay near the Lanes' home on the northeastern shore of the Bay because the flow from the Perdido River tends to push the flow from Elevenmile Creek toward the northeastern shore. Because Dr. Livingston determined that the nutrient loadings from the mill that occurred in 1988 and 1989 did not adversely impact the food web of Perdido Bay, he recommended effluent limits for ammonia nitrogen, orthophosphate, and total phosphorous that were correlated with mill loadings of these nutrients in those years. The Department used Dr. Livingston’s data, and did its own analyses, to establish WQBELs for orthophosphate for drought conditions and for nitrate-nitrite. WQBELs were ultimately developed for total ammonia, orthophosphate, nitrate-nitrite, total phosphorus, BOD, color, and soluble inorganic nitrogen. The WQBELs in the proposed permit were developed to assure compliance with water quality standards under conditions of pollutant loadings at the daily limit (based on a monthly average) during low flow in the receiving waters. Petitioners did not dispute that the proposed WWTP is capable of achieving the TBELs and WQBELs. Their main complaint is that the WQBELs are not adequate to protect the receiving waters. A wetland pilot project was constructed in 1990 at the Cantonment mill into which effluent from the mill has been discharged. The flora and fauna of the pilot wetland project have been monitored to evaluate how they are affected by IP’s effluent. An effluent distribution system is proposed for the wetland tract to spread the effluent out over the full width of the wetlands. This would be accomplished by a system of berms running perpendicular to the flow of water through the wetlands, and gates and other structures in and along the berms to gather and redistribute the flow as it moves in a southerly direction toward Perdido Bay. The design incorporates four existing tram roads that were constructed on the wetland tract to serve the past and present silvicultural activities there. The tram roads, with modifications, would serve as the berms in the wetland distribution system. As the effluent is discharged from the pipeline, it would be re-aerated and distributed across Berm 1 through a series of adjustable, gated openings. Mixing with naturally occurring waters, the effluent would move by gravity to the next lower berm. The water will re-collect behind each of the vegetated berms and be distributed again through each berm. The distance between the berms varies from a quarter to a half mile. Approximately 70 percent of the effluent discharged into the wetland would flow a distance of approximately 2.3 miles to Perdido Bay. The remaining 30 percent of the effluent would flow a somewhat shorter distance to lower Elevenmile Creek. A computer simulation performed by Dr. Wade Nutter indicated that the effluent would move through the wetland tract at a velocity of approximately a quarter-of-a-foot per second and the depth of flow across the wetland tract will be 0.6 inches. It would take four or five days for the effluent to reach lower Elevenmile Creek and Perdido Bay. As the treated effluent flows through the wetland tract, there will be some removal of nutrients by plants and soil. Nitrogen and phosphorous are expected to be reduced approximately ten percent. BOD in the effluent is expected to be reduced approximately 90 percent. Construction activities associated with the effluent pipeline, berm, and control structures in the wetland tract, as originally proposed, were permitted by the Department through issuance of a Wetland Resource Permit to IP. The United States Army Corps of Engineers has also permitted this work. Petitioners did not challenge those permits. A wetland monitoring program is required by the proposed permit. The stated purpose of the monitoring program is to assure that there are no significant adverse impacts to the wetland tract, including Tee and Wicker Lakes. After the discharge to the wetland tract commences, the proposed permit requires IP to submit wetland monitoring reports annually to the Department. A monitoring program was also developed by Dr. Livingston and other IP consultants to monitor the impacts of the proposed discharge on Elevenmile Creek and Perdido Bay. It was made a part of the proposed permit. The proposed Consent Order establishes a schedule for the construction activities associated with the proposed WWTP upgrades and the effluent pipeline and for incremental relocation of the mill's discharge from Elevenmile Creek to the wetland tract. IP is given two years to complete construction activities and begin operation of the new facilities. At the end of the construction phase, least 25 percent of the effluent is to be diverted to the wetland tract. The volume of effluent diverted to the wetlands is to be increased another 25 percent every three months thereafter. Three years after issuance of the permit, 100 percent of the effluent would be discharged into the wetland tract and there would no longer be a discharge into Elevenmile Creek. The proposed Consent Order establishes interim effluent limits that would apply immediately upon the effective date of the Consent Order and continue during the two-year construction phase when the mill would continue to discharge into Elevenmile Creek. Other interim effluent limits would apply during the 12- month period following construction when the upgraded WWTP would be operating and the effluent would be incrementally diverted from Elevenmile Creek to the wetland tract. A third set of interim effluent limits would apply when 100 percent of the effluent is discharged into the wetland tract. IP is required by the Consent Order to submit quarterly reports of its progress toward compliance with the required corrective actions and deadlines. Project Changes After the issuance of the Final Order in 05-1609, IP modified its manufacturing process to eliminate the production of white paper. IP now produces brown paper for packaging material and “fluff” pulp used in such products as filters and diapers. IP’s new manufacturing processes uses substantially smaller amounts of bleach and other chemicals that must be treated and discharged. IP reduced its discharge of BOD components, salts that increase the specific conductance of the effluent, adsorbable organic halides, and ammonia. IP also reduced the odor associated with its discharge. In the findings that follow, the portion of the Rainwater Tract into which IP proposes to discharge and distribute its effluent will be referred to as the “effluent distribution system,” which is the term used by Dr. Nutter in his 2008 “White Paper” (IP Exhibit 23). The effluent distribution system includes the berms and other water control structures as well as all of the natural areas over which IP’s effluent will flow to Perdido Bay. Most of the existing ditches, sloughs, and depressions in the effluent distribution system are ephemeral, holding water only after heavy rainfall or during the wet season. Even the more frequently wetted features, other than Tee and Wicker Lakes, intermittently dry out. There is currently little connectivity among the small water bodies that would allow fish and other organisms to move across the site. Fish and other organisms within these water bodies are exposed to wide fluctuations in specific conductivity, pH, and DO. When the water bodies dry out, the minnows and other small fish die. New populations of fish enter these water bodies from Elevenmile Creek during high water conditions, or on the feet of water birds. IP's consultants conducted an extensive investigation and evaluation of animal and plant communities in the Rainwater Tract in coordination with scientists from the Department and the Florida Fish and Wildlife Conservation Commission. Among the habitats that were identified and mapped were some wet prairies, which are designated “S-2," or imperiled, in the Florida Natural Area Inventory. In these wet prairies are rare and endangered pitcher plants. IP modified the design of the proposed effluent distribution system to shorten the upper berms and remove 72.3 acres of S-2 habitat. The total area of the system was reduced from 1,484 acres to 1,381 acres. The proposed land management activities within the effluent distribution system are intended to achieve restoration of historic ecosystems, including the establishment and maintenance of tree species appropriate to the various water depths in the system, and the removal of exotic and invasive plant species. A functional assessment of the existing and projected habitats in the effluent distribution system was performed. The Department concluded that IP’s project would result in a six percent increase in overall wetland functional value within the system. That estimate accounts for the loss of some S-2 habitat, but does not include the benefits associated with IP’s conservation of S-2 habitat and other land forms outside of the effluent distribution system. IP proposes to place in protected conservation status 147 acres of wet prairie, 115 acres of seepage slope, and 72 acres of sand hill lands outside the effluent distribution system. The total area outside of the wetland distribution system that the Consent Order requires IP to perpetually protect and manage as conservation area is 1,188 acres. The Consent Order was modified to incorporate many of the wetland monitoring provisions that had previously been a part of the former experimental use of wetlands authorization. IP proposes to achieve compliance with all proposed water quality standards and permit limits by the end of the schedule established in the Consent Order, including the water quality standards for specific conductance, pH, turbidity, and DO, which IP had previously sought exceptions for pursuant to Florida Administrative Code Rule 62-660.300(1). Limitation of Factual Issues As explained in the Conclusions of Law, the doctrine of collateral estoppel bars the parties in these consolidated cases from re-litigating factual issues that were previously litigated by them in DOAH Case No. 05-1609. The Department’s Final Order of August 8, 2007, determined that IP had provided reasonable assurance that the NPDES permit, Consent Order, exception for the experimental use of wetlands, and variance were in compliance with all applicable statutes and rules, except for the following area: the evidence presented by IP was insufficient to demonstrate that IP’s wastewater effluent would not cause significant adverse impact to the biological community of the wetland tract, including Tee and Wicker Lakes. Following a number of motions and extensive argument on the subject of what factual issues raised by Petitioners are proper for litigation in this new proceeding, an Order was issued on June 2, 2009, that limited the case to two general factual issues: Whether the revised Consent Order and proposed permit are valid with respect to the effects of the proposed discharge on the wetland system, including Tee and Wicker Lakes, and with respect to any modifications to the effluent distribution and treatment functions of the wetland system following the Final Order issued in DOAH Case No. 05- 1609; and Whether the December 2007 report of the Livingston team demonstrates that the WQBELS are inadequate to prevent water quality violations in Perdido Bay. Petitioners’ Disputes Petitioners’ proposed recommended orders include arguments that are barred by collateral estoppel. For example, Jacqueline Lane restates her opinions about physical and chemical processes that would occur if IP’s effluent is discharged into the wetlands, despite the fact that some of these opinions were rejected in DOAH Case No. 05-1609. Dr. Lane believes that IP’s effluent would cause adverse impacts from high water temperatures resulting from color in IP’s effluent. There is already color in the waters of the effluent distribution system under background conditions. The increased amount of shading from the trees that IP is planting in the effluent distribution system would tend to lower water temperatures. Peak summer water temperatures would probably be lowered by the effluent. Petitioners evidence was insufficient to show that the organisms that comprise the biological community of the effluent distribution system cannot tolerate the expected range of temperatures. Dr. Lane also contends that the BOD in IP's effluent would deplete DO in the wetlands and Tee and Wicker Lakes. Her contention, however, is not based on new data about the effluent or changes in the design of the effluent distribution system. There is a natural, wide fluctuation in DO in the wetlands of the effluent distribution system because DO is affected by numerous factors, including temperature, salinity, atmospheric pressure, turbulence, and surface water aeration. There are seasonal changes in DO levels, with higher levels in colder temperatures. There is also a daily cycle of DO, with higher levels occurring during the day and lower levels at night. It is typical for DO levels in wetlands to fall below the Class III water quality standard for DO, which is five milligrams per liter (mg/l). An anaerobic zone in the water column is beneficial for wetland functions. DO levels in the water bodies of the effluent distribution system currently range from a high of 11 to 12 mg/l to a low approaching zero. The principal factor that determines DO concentrations within a wetland is sediment oxygen demand (SOD). SOD refers to the depletion of oxygen from biological responses (respiration) as well as oxidation-reduction reactions within the sediment. The naturally occurring BOD in a wetland is large because of the amount of organic material. The BOD associated with IP’s effluent would be a tiny fraction of the naturally occurring BOD in the effluent distribution system and would be masked by the effect of the SOD. It was estimated that the BOD associated with IP's effluent would represent only about .00000000001 percent of the background BOD, and would have an immeasurable effect. Dr. Pruitt’s testimony about oxygen dynamics in a wetland showed that IP’s effluent should not cause a measurable decrease in DO levels within the effluent distribution system, including Tee and Wicker Lakes. FOPB and James Lane assert that only 200 acres of the effluent distribution system would be inundated by IP’s effluent, so that the alleged assimilation or buffering of the chemical constituents of the effluent would not occur. That assertion misconstrues the record evidence. About 200 acres of the effluent distribution system would be permanently inundated behind the four berms. However, IP proposes to use the entire 1,381-acre system for effluent distribution. The modifications to the berms and the 72-acre reduction in the size of the effluent distribution system would not have a material effect on the assimilative capacity of system. The residence time and travel time of the effluent in the system, for example, would not be materially affected. Variability in topography within the effluent distribution system and in rainfall would affect water depths in the system. The variability in topography, including the creation of some deeper pools, would contribute to plant and animal diversity and overall biological productivity within the system. The pH of the effluent is not expected to change the pH in the effluent distribution system because of natural buffering in the soils. The specific conductance (saltiness) of IP’s effluent is not high enough to adversely affect the biological community in the fresh water wetlands of the effluent distribution system. IP is already close to maintaining compliance with the water quality standard for specific conductance and would be in full compliance by the end of the compliance schedule established in the proposed Consent Order. After the 2007 conversion to brown paper manufacturing, IP’s effluent has shown no toxicity. The effluent has passed the chronic toxicity test, which analyzes the potential for toxicity from the whole effluent, including any toxicity arising from additive or synergistic effects, on sensitive test organisms. Dr. Lane points out that the limits for BOD and TSS in the proposed NPDES permit exceed the limits established by Department rule for discharges of municipal wastewater into wetlands. However, paper mill BOD is more recalcitrant in the environment than municipal wastewater BOD and less “bio- available” in the processes that can lower DO. In addition, the regulatory limits for municipal wastewater are technology-based, representing “secondary treatment.” The secondary treatment technology is not applicable to IP’s wastewater. Sampling in the pilot wetland at the paper mill revealed a diversity of macroinvertebrates, including predator species, and other aquatic organisms. Macroinvertebrates are a good measure of the health of a water body because of their fundamental role in the food web and because they are generally sensitive to pollutants. Petitioners contend that the pilot wetland at the paper mill is not a good model for the effect of the IP’s effluent in the wetland distribution system, primarily because of the small amount of effluent that has been applied to the pilot wetland. Although the utility of the pilot wetland data is diminished in this respect, it is not eliminated. The health of the biological community in the pilot wetland contributes to IP’s demonstration of reasonable assurance that the biological community in the effluent distribution system would not be adversely affected. The effluent would not have a significant effect on the salinity of Tee and Wicker Lakes. Under current conditions, the lakes have a salinity of less than one part per thousand 25 percent of the time, less than 10 parts per thousand 53 percent of the time, and greater than 10 parts per thousand 22 percent of the time. In comparison, marine waters have a salinity of 2.7 parts per thousand. IP’s effluent would not affect the lower end of the salinity range for Tee and Wicker Lakes, and would cause only a minor decrease in the higher range. That minor decrease should not adversely affect the biota in Tee and Wicker Lakes or interfere with their nursery functions. The proposed hydrologic loading rate of the effluent amounts to an average of six-tenths of an inch over the area of effluent distribution system. The addition of IP’s effluent to the wetlands of the effluent distribution system and the creation of permanent pools would allow for permanent fish populations and would increase the opportunity for fish and other organisms to move across the effluent distribution system. Biological diversity and productivity is likely to be increased in the effluent distribution system. By improving fish habitat, the site would attract wading birds and other predatory birds. Although the site would not be open to public use (with the exception of Tee and Wicker Lakes), recreational opportunities could be provided by special permission for guided tours, educational programs, and university research. Even if public access were confined to Tee and Wicker Lakes, that would not be a reduction in public use as compared to the existing situation. IP’s discharge, including its discharges subject to the interim limits established in the Consent Order, would not interfere with the designated uses of the Class III receiving waters, which are the propagation and maintenance of a healthy, well-balanced population of fish and wildlife. The wetlands of the effluent distribution system are the “receiving waters” for IP’s discharge. The proposed project would not be unreasonably destructive to the receiving waters, which would involve a substantial alteration in community structure and function, including the loss of sensitive taxa and their replacement with pollution-tolerant taxa. The proposed WQBELs would maintain the productivity in Tee and Wicker Lakes. There would be no loss of the habitat values or nursery functions of the lakes which are important to recreational and commercial fish species. IP has no reasonable, alternative means of disposing of its wastewater other than by discharging it into waters of the state. IP has demonstrated a need to meet interim limits for a period of time necessary to complete the construction of its alternative waste disposal system. The interim limits and schedule for coming into full compliance with all water quality standards, established in the proposed Consent Order, are reasonable. The proposed project is important and beneficial to the public health, safety, and welfare because (1) economic benefits would accrue to the local and regional economy from the operation of IP’s paper mill, (2) Elevenmile Creek would be set on a course of recovery, (3) the wetlands of the effluent distribution system would become a site of greater biological diversity and productivity, (4) the environmental health of Perdido Bay would be improved, (5) the Department’s decades-long enforcement action against IP would be concluded, (6) substantial areas of important habitat would be set aside for permanent protection, and (7) the effluent distribution system would yield important information on a multitude of scientific topics that were debated by these parties. The proposed project would not adversely affect the conservation of fish or wildlife or their habitats. The proposed project would not adversely affect fishing or water-based recreational values or marine productivity in the vicinity of the proposed discharge. There is no Surface Water Improvement and Management Plan applicable to IP’s proposed discharge. The preponderance of the record evidence establishes reasonable assurance that IP’s proposed project would comply with all applicable laws and that the Consent Order establishes reasonable terms and conditions to resolve the Department’s enforcement action against IP for past violations.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is: RECOMMENDED that the Department enter a final order granting NPDES Permit No. FL0002526 and approving Consent Order No. 08-0358. DONE AND ENTERED this 27th day of January, 2010, in Tallahassee, Leon County, Florida. BRAM D. E. CANTER Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 27th day of January, 2010.
The Issue The issue is whether Respondents should be subject to civil penalties and required to submit a Compliance Plan for the reasons stated in the Administrative Complaint and Order filed on January 8, 2002.
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: Background In this enforcement action, Petitioner, Southwest Florida Water Management District (District), proposes to assess civil penalties against, and require a compliance plan from, Respondents, Balm Associates, Inc. (Balm) and Goodson Farms, Inc. (Goodson), on the grounds that from March 1999 through July 2001 they made water withdrawals from certain property in Hillsborough County, Florida, without a water use permit, and after a permit was obtained in August 2001, they continued to exceed the annual average daily withdrawals authorized under the permit through the month of November 2001, or just prior to the preparation and issuance of the Administrative Complaint and Order (Complaint).1 While not denying that excessive pumpages may have occurred, and that a permit was not obtained until August 2001, Balm points out that it is the owner-lessor of the property and not the consumptive user of the water, and contends that the District has no authority to enforce its rules against, and recover civil penalties from, the non-user of the water. In its request for a hearing, Goodson did not specifically dispute the allegation that it consumed water without a permit, or exceeded the withdrawal limits under the new permit, but contended instead that the limits were unrealistic and should be modified. At the final hearing, however, Goodson disputed the accuracy of the water consumption figures used in the Complaint. The District is the administrative agency charged with the responsibility to conserve, protect, manage, and control water resources within its boundaries and to administer and enforce Chapter 373, Florida Statutes. Balm is a corporation registered to do business in the State of Florida. Its mailing address is 2101 Huntington Avenue, Sarasota, Florida 34232. It owns approximately 220 acres of land in Section 28, Township 31 South, Range 21 East, in Hillsborough County, Florida, which is the site of the alleged wrongdoing. Goodson is a corporation registered to do business in the State of Florida. Its mailing address is Post Office Box 246, Balm, Florida 33503. Goodson is in the farming business and operates a total of 13 farms, including the farm at issue in this proceeding. Permit Requirements Under Rule 40D-2.041(1), Florida Administrative Code, a water use permit is required whenever total withdrawal capacity from any source or combined sources is greater than or equal to 1,000,000 gallons per day (gpd); annual average withdrawal from any source or combined sources is greater than or equal to 100,000 gpd; or withdrawal is from a well having an outside diameter of 6 inches or more at the surface. Rule 40D-2.351(1), Florida Administrative Code, provides that a permittee must notify the District within 30 days of the sale or conveyance of permitted water withdrawal facilities or the land on which the facilities are located. The same rule also provides that where a permit has been issued to a party whose ownership or legal control of the permitted water withdrawal facilities subsequently ends, the party who assumes control over the facilities may apply to transfer the permit to himself or herself up to the renewal date of the transferor's permit. Finally, Rule 40D-2.351(2), Florida Administrative Code, provides that until a permit is transferred or a new permit is obtained, the party subsequently controlling the permitted water withdrawal facilities will be in violation of District rules for making withdrawals without the required permit. History of Permits on the Property On September 29, 1989, the District issued Water Use Permit No. 207135.001 (the .001 permit) to James Brown (Brown) and B & T Growers Partnership (B & T) for water withdrawals from one well for agricultural purposes on Balm's property. The .001 permit authorized annual average withdrawals of 102,000 gpd of groundwater for agricultural irrigation. On August 29, 1990, the District adopted new rules applicable to District permits within the Eastern Tampa Bay Water Use Caution Area (ETBWUCA). The .001 permit was within the ETBWUCA, and Brown and B & T were provided with a Notice of Permit Modification and new Permit Conditions. The new conditions became effective November 15, 1990. New Condition No. 5 provided that By July 31, 1995, all permitted withdrawal points shall be equipped with totalizing flow meters or other measuring devices as approved in writing by the Director, Resource Regulation Department. Such devices shall have and maintain accuracy within five percent of the actual flow installed. On December 14, 1992, the District approved the transfer of the .001 permit from Brown and B & T to B. Kenda Produce. The Unpermitted Water Withdrawals On June 30, 1997, Goodson entered into a two-year agricultural lease with Balm to use a portion of the property, including acreage previously used by B. Kendra Produce. At the time the lease was entered into, neither Respondent applied to the District to have the .001 permit transferred from B. Kendra Produce. It can be reasonably inferred from the evidence that after the first lease expired, the parties continued to execute new lease agreements at least through the time of the hearing. The portion of the property which Goodson leased and farmed is referred to as the "Sweat Loop Farm" and consists of approximately 100 acres. There is one well with an outside diameter of 10 inches at the surface located on the Sweat Loop Farm. The well's total withdrawal capacity is approximately 1,500 gallons per minute (gpm), which is over 1,000,000 gpd. Thus, withdrawals from the well required a water use permit. As noted earlier, Goodson operates a total of 13 farms on approximately 2,500 acres of land. There are approximately 15 wells on all 13 farms, including the Sweat Loop Farm. Michael E. Hare, an irrigation supervisor who is responsible for the irrigation of all 13 of Goodson's farms, installed a total of approximately 8 meters on the farms, including the meter on the Sweat Loop Farm. A totalizing flow meter, which was made by MiCrometer, was installed at the Sweat Loop Farm in June 1997. Mr. Hare acknowledged that he was familiar with MiCrometer meters and would be aware if the MiCrometer flow meter on the Sweat Loop Farm was not functioning properly. Whenever metering devices on the various Goodson farms have malfunctioned in the past, Mr. Hare has taken the malfunctioning meter to a metering company to be fixed. Goodson began irrigating the Sweat Loop Farm in June 1997. Since that time, Goodson has been the sole water user of the well on the farm. In March 1999, Goodson began submitting to the District monthly pumpage reports for the groundwater withdrawals on the Sweat Loop Farm. Although some unmeasured withdrawals presumably occurred prior to March 1999, the Complaint does not identify these as being a violation. Mr. Hare and other supervisors are responsible for collecting the meter readings which go on the monthly pumpage reports and providing them to the District. The information on the reports includes the permit number; the last month's meter reading; the current month's meter reading; the total gallons of water pumped for the current month; the meter total; and the meter factor. To determine the average daily withdrawal on the Sweat Loop Farm, the District relied upon the calculations provided by Goodson as to the total gallons of water pumped for the month and divided this number by 30 days. From March 1999 through July 2001, these quantities were as follows: MONTH/YEAR AVERAGE DAILY PUMPAGE March 1999 April 1999 531,487 No data available May 1999 364,930 June 1999 0 July 1999 0 August 1999 57,410 September 1999 49,563 October 1999 222,667 November 1999 250,667 December 1999 755,003 January 2000 689,433 February 2000 695,073 March 2000 544,427 April 2000 305,153 May 2000 597,720 June 2000 0 July 2000 62,120 August 2000 86,370 September 2000 123,233 October 2000 602,020 November 2000 409,550 December 2000 145,823 January 2001 957,690 February 2001 890,213 March 2001 391,280 April 2001 467,640 May 2001 617,177 June 2001 0 July 2001 0 Under Rule 40D-2.041(1)(a)-(c), Florida Administrative Code, a water use permit was required for Goodson's withdrawals since the well's total withdrawal capacity is approximately 1,500 gpm, which is greater than 1,000,000 gpd; the annual average withdrawals exceeded 100,000 gpd; and the well has an outside diameter of 10 inches at the surface. The withdrawals on the Sweat Loop Farm were not authorized by the .001 permit since neither Goodson or Balm was a permittee under the permit. Even if Goodson could rely on the permit, which it cannot, pumpage data provided by Goodson reflects that the water withdrawals (except for nine months) were in excess of that authorized by the permit. On June 16, 2000, the District mailed a Notice of Non-Compliance for excessive water withdrawals to Goodson. The Notice indicated that if the pumpage values submitted by Goodson were incorrect, Goodson was to explain the error and provide corrected quantities. On June 26, 2000, the District received a written response to the Notice of Non-Compliance from the superintendent of the Sweat Loop Farm who indicated that the pumpage values were correct, and that the excess usage was due to a "serious drought condition" which had caused a "significant financial hardship on [the] farm." The response also indicated that Goodson would contact Mr. Haftel, owner of Balm, to request that he "revise the water use permit for spring crops." On November 22, 2000, the District mailed Goodson a Notice of Violation indicating that the quantities authorized by the .001 permit were still being exceeded and that the District might seek monetary penalties if Goodson failed to come into compliance within 30 days. Despite the foregoing Notice, Goodson continued to make withdrawals without a permit and in excess of the quantities formerly authorized under the .001 permit until August 2001 when a new permit was finally obtained. Issuance of a New Water Use Permit On January 2, 2001, the District received an application for a General Water Use Permit seeking to modify the .001 permit to increase the withdrawal quantities and to transfer the permit from B. Kendra Produce to Balm. "Seymour Haftel/ Balm Associates, Inc." was listed as the applicant, and "Donn Goodson" from " Goodson Farms" was listed as the contact or consultant. Mr. Haftel signed the application on behalf of Balm. Goodson assisted Balm in securing the permit for the Sweat Loop Farm because Goodson wanted more water for irrigation purposes. Section 2.1 of the Basis of Review for Water Use Permit Application, adopted and incorporated by reference by Rule 40D-2.091, Florida Administrative Code, provides that "[a]pplications for leased property, except property leased from the District, must be either a joint application in the name of the lessee and the property owner(s) or be only in the name of the property owner(s)." In a Request for Additional Information mailed to Balm on January 29, 2001, the District asked whether Goodson should be listed as co-applicant on the application. On April 27, 2001, Balm submitted a response which indicated that Goodson should not be listed as co-applicant. On August 6, 2001, the District issued Water Use Permit No. 200007135.002 (the .002 permit) to Seymour Haftel/Balm Associates, Inc. authorizing an increase in the annual average withdrawals to 224,300 gpd. The permit had an expiration date of September 29, 2009. The permit contained a number of special conditions, none of which were challenged by Balm. Unauthorized Withdrawals Under the .002 Permit Special Condition No. 2 of the .002 permit requires in part that the permittee: continue to maintain and operate the existing non-resettable, totalizing flow meter(s), or other flow measuring device(s) as approved by the Regulation Department Director, Resource Regulation, for District ID No(s), Permittee ID No(s)[,] G-1. Such device(s) shall maintain an accuracy within five percent of the actual flow as installed. Total withdrawal and meter readings from each metered withdrawal shall be recorded on a monthly basis and reported to the Permit Data Section, Records and Data Department, (using District forms) on or before the tenth day of the following month. In the event a permittee chooses not to use a totalizing flow meter, as required by Special Condition No. 2, the District will review information provided by the measuring device's manufacturer to determine if the measuring device would maintain a five percent accuracy as required by the Condition. The meters have to be monitored and calibrated periodically for accuracy. It is the permittee's responsibility to comply with the conditions of the permit, including Special Condition No. 2, which requires the submittal of accurate pumpage reports. Goodson submitted the meter readings on behalf of Balm beginning in September 2001, which covered the withdrawals for the month of August 2001. The District relied on the meter readings submitted by Goodson to determine the annual average daily pumpage calculation for the .002 permit. The calculation is a running 12-month average, whereby each month the annual average daily quantity is recalculated based on the previous 12-month pumpage. The running annual average daily pumpage and percentage of pumpage which exceeded the .002 permit from August 2001 through May 2002 are as follows: MONTH/YEAR ANNUAL AVERAGE DAILY PUMPAGE PERCENTAGE OVERPUMPED August 2001 378,462 69 percent September 2001 382,622 71 percent October 2001 376,687 68 percent November 2001 383,008 71 percent December 2001 379,212 69 percent January 2002 327,343 46 percent February 2002 321,530 43 percent March 2002 350,701 56 percent April 2002 356,013 59 percent May 2002 338,131 51 percent As the foregoing data reflects, the withdrawals from the Sweat Loop Farm were in excess of that authorized by the .002 permit from August 2001 through May 2002.
