SAVE OUR BAYS, AIR AND CANALS, INC. vs DEPARTMENT OF ENVIRONMENTAL PROTECTION, 01-001463RP (2001)
Division of Administrative Hearings, Florida Filed:Tallahassee, Florida Apr. 13, 2001 Number: 01-001463RP Latest Update: Jun. 06, 2003

The Issue Whether proposed Rule Chapter 62-303, Florida Administrative Code, which describes how the Department of Environmental Protection will exercise its authority under Section 403.067, Florida Statutes, to identify and list those surface waters in the state that are impaired for purposes of the state's total maximum daily load (commonly referred to as "TMDL") program, is an "invalid exercise of delegated legislative authority," within the meaning of Chapter 120, Florida Statutes, for the reasons asserted by Petitioners.

Findings Of Fact Based upon the evidence adduced at hearing and the record as a whole, the following findings of fact are made to supplement the factual stipulations contained in the parties' Prehearing Stipulation: State TMDL Legislation Over the last 30 years, surface water quality management in Florida, like in the rest of the United States, has focused on the control of point sources of pollution (primarily domestic and industrial wastewater) through the issuance, to point source dischargers, of National Pollutant Discharge Elimination System (NPDES) permits, which specify effluent-based standards with which the permit holders must comply. Although "enormously successful in dealing with . . . point sources" of pollution, the NPDES program has not eliminated water quality problems largely because discharges from other sources of pollution (nonpoint sources) have not been as successfully controlled. In the late 1990's, the Department recognized that, to meet Florida's water quality goals, it was going to have to implement a TMDL program for the state. Wanting to make absolutely sure that it had the statutory authority to do so, the Department sought legislation specifically granting it such authority. Jerry Brooks, the deputy director of the Department's Division of Water Resource Management, led the Department's efforts to obtain such legislation. He was assisted by Darryl Joyner, a Department program administrator responsible for overseeing the watershed assessment and groundwater protection sections within the Division of Water Resource Management. Participating in the drafting of the legislation proposed by the Department, along with Mr. Brooks and Mr. Joyner, were representatives of regulated interests. No representatives from the environmental community actively participated in the drafting of the proposed legislation. The Department obtained the TMDL legislation it wanted when the 1999 Florida Legislature enacted Chapter 99-223, Laws of Florida, the effective date of which was May 26, 1999. Section 1 of Chapter 99-223, Laws of Florida, added the following to the definitions set forth in Section 403.031, Florida Statutes, which define "words, phrases or terms" for purposes of "construing [Chapter 403, Florida Statutes], or rules or regulations adopted pursuant [t]hereto": (21) "Total maximum daily load" is defined as the sum of the individual wasteload allocations for point sources[11] and the load allocations for nonpoint sources and natural background. Prior to determining individual wasteload allocations and load allocations, the maximum amount of a pollutant that a water body or water segment can assimilate from all sources without exceeding water quality standards must first be calculated. Section 4 of Chapter 99-223, Laws of Florida, added language to Subsection (1) of Section 403.805, Florida Statutes, providing that the Secretary of the Department, not the Environmental Regulation Commission, "shall have responsibility for final agency action regarding total maximum daily load calculations and allocations developed pursuant to s. 403.067(6)," Florida Statutes. The centerpiece of Chapter 99-223, Laws of Florida, was Section 3 of the enactment, which created Section 403.067, Florida Statutes, dealing with the "[e]stablishment and implementation of total maximum daily loads." Section 403.067, Florida Statutes, was amended in 2000 (by Chapter 2000-130, Laws of Florida) and again in 2001 (by Chapter 2001-74, Laws of Florida). It now reads, in its entirety, as follows: LEGISLATIVE FINDINGS AND INTENT.-- In furtherance of public policy established in s. 403.021, the Legislature declares that the waters of the state are among its most basic resources and that the development of a total maximum daily load program for state waters as required by s. 303(d) of the Clean Water Act, Pub. L. No. 92-500, 33 U.S.C. ss. 1251 et seq. will promote improvements in water quality throughout the state through the coordinated control of point and nonpoint sources of pollution.[12] The Legislature finds that, while point and nonpoint sources of pollution have been managed through numerous programs, better coordination among these efforts and additional management measures may be needed in order to achieve the restoration of impaired water bodies. The scientifically based total maximum daily load program is necessary to fairly and equitably allocate pollution loads to both nonpoint and point sources. Implementation of the allocation shall include consideration of a cost- effective approach coordinated between contributing point and nonpoint sources of pollution for impaired water bodies or water body segments and may include the opportunity to implement the allocation through nonregulatory and incentive-based programs. The Legislature further declares that the Department of Environmental Protection shall be the lead agency in administering this program and shall coordinate with local governments, water management districts, the Department of Agriculture and Consumer Services, local soil and water conservation districts, environmental groups, regulated interests, other appropriate state agencies, and affected pollution sources in developing and executing the total maximum daily load program. LIST OF SURFACE WATERS OR SEGMENTS.-- In accordance with s. 303(d) of the Clean Water Act, Pub. L. No. 92-500, 33 U.S.C. ss. 1251 et seq., the department must submit periodically to the United States Environmental Protection Agency a list of surface waters or segments for which total maximum daily load assessments will be conducted. The assessments shall evaluate the water quality conditions of the listed waters and, if such waters are determined not to meet water quality standards, total maximum daily loads shall be established, subject to the provisions of subsection (4). The department shall establish a priority ranking and schedule for analyzing such waters. The list, priority ranking, and schedule cannot be used in the administration or implementation of any regulatory program. However, this paragraph does not prohibit any agency from employing the data or other information used to establish the list, priority ranking, or schedule in administering any program. The list, priority ranking, and schedule prepared under this subsection shall be made available for public comment, but shall not be subject to challenge under chapter 120. The provisions of this subsection are applicable to all lists prepared by the department and submitted to the United States Environmental Protection Agency pursuant to s. 303(d) of the Clean Water Act, Pub. L. No. 92-500, 33 U.S.C. ss. 1251 et seq., including those submitted prior to the effective date of this act, except as provided in subsection (4). If the department proposes to implement total maximum daily load calculations or allocations established prior to the effective date of this act, the department shall adopt those calculations and allocations by rule by the secretary pursuant to ss. 120.536(1) and 120.54 and paragraph (6)(d). ASSESSMENT.-- Based on the priority ranking and schedule for a particular listed water body or water body segment, the department shall conduct a total maximum daily load assessment of the basin in which the water body or water body segment is located using the methodology developed pursuant to paragraph (b). In conducting this assessment, the department shall coordinate with the local water management district, the Department of Agriculture and Consumer Services, other appropriate state agencies, soil and water conservation districts, environmental groups, regulated interests, and other interested parties. The department shall adopt by rule a methodology for determining those waters which are impaired. The rule shall provide for consideration as to whether water quality standards codified in chapter 62- 302, Florida Administrative Code, are being exceeded, based on objective and credible data, studies and reports, including surface water improvement and management plans approved by water management districts under s. 373.456 and pollutant load reduction goals developed according to department rule. Such rule also shall set forth: Water quality sample collection and analysis requirements, accounting for ambient background conditions, seasonal and other natural variations; Approved methodologies; Quality assurance and quality control protocols; Data modeling; and Other appropriate water quality assessment measures. If the department has adopted a rule establishing a numerical criterion for a particular pollutant, a narrative or biological criterion may not be the basis for determining an impairment in connection with that pollutant unless the department identifies specific factors as to why the numerical criterion is not adequate to protect water quality. If water quality non-attainment is based on narrative or biological criteria, the specific factors concerning particular pollutants shall be identified prior to a total maximum daily load being developed for those criteria for that surface water or surface water segment. APPROVED LIST.-- If the department determines, based on the total maximum daily load assessment methodology described in subsection (3), that water quality standards are not being achieved and that technology- based effluent limitations[13] and other pollution control programs under local, state, or federal authority, including Everglades restoration activities pursuant to s. 373.4592 and the National Estuary Program, which are designed to restore such waters for the pollutant of concern are not sufficient to result in attainment of applicable surface water quality standards, it shall confirm that determination by issuing a subsequent, updated list of those water bodies or segments for which total maximum daily loads will be calculated. In association with this updated list, the department shall establish priority rankings and schedules by which water bodies or segments will be subjected to total maximum daily load calculations. If a surface water or water segment is to be listed under this subsection, the department must specify the particular pollutants causing the impairment and the concentration of those pollutants causing the impairment relative to the water quality standard. This updated list shall be approved and amended by order of the department subsequent to completion of an assessment of each water body or water body segment, and submitted to the United States Environmental Protection Agency. Each order shall be subject to challenge under ss. 120.569 and 120.57. REMOVAL FROM LIST.-- At any time throughout the total maximum daily load process, surface waters or segments evaluated or listed under this section shall be removed from the lists described in subsection (2) or subsection (4) upon demonstration that water quality criteria are being attained, based on data equivalent to that required by rule under subsection (3). CALCULATION AND ALLOCATION.-- Calculation of total maximum daily load. Prior to developing a total maximum daily load calculation for each water body or water body segment on the list specified in subsection (4), the department shall coordinate with applicable local governments, water management districts, the Department of Agriculture and Consumer Services, other appropriate state agencies, local soil and water conservation districts, environmental groups, regulated interests, and affected pollution sources to determine the information required, accepted methods of data collection and analysis, and quality control/quality assurance requirements. The analysis may include mathematical water quality modeling using approved procedures and methods. The department shall develop total maximum daily load calculations for each water body or water body segment on the list described in subsection (4) according to the priority ranking and schedule unless the impairment of such waters is due solely to activities other than point and nonpoint sources of pollution. For waters determined to be impaired due solely to factors other than point and nonpoint sources of pollution, no total maximum daily load will be required. A total maximum daily load may be required for those waters that are impaired predominantly due to activities other than point and nonpoint sources. The total maximum daily load calculation shall establish the amount of a pollutant that a water body or water body segment may receive from all sources without exceeding water quality standards, and shall account for seasonal variations and include a margin of safety that takes into account any lack of knowledge concerning the relationship between effluent limitations and water quality. The total maximum daily load may be based on a pollutant load reduction goal developed by a water management district, provided that such pollutant load reduction goal is promulgated by the department in accordance with the procedural and substantive requirements of this subsection. Allocation of total maximum daily loads. The total maximum daily loads shall include establishment of reasonable and equitable allocations of the total maximum daily load among point and nonpoint sources that will alone, or in conjunction with other management and restoration activities, provide for the attainment of water quality standards and the restoration of impaired waters. The allocations may establish the maximum amount of the water pollutant from a given source or category of sources that may be discharged or released into the water body or water body segment in combination with other discharges or releases. Allocations may also be made to individual basins and sources or as a whole to all basins and sources or categories of sources of inflow to the water body or water body segments. Allocations shall be designed to attain water quality standards and shall be based on consideration of the following: Existing treatment levels and management practices; Differing impacts pollutant sources may have on water quality; The availability of treatment technologies, management practices, or other pollutant reduction measures; Environmental, economic, and technological feasibility of achieving the allocation; The cost benefit associated with achieving the allocation; Reasonable timeframes for implementation; Potential applicability of any moderating provisions such as variances, exemptions, and mixing zones; and The extent to which nonattainment of water quality standards is caused by pollution sources outside of Florida, discharges that have ceased, or alterations to water bodies prior to the date of this act. Not later than February 1, 2001, the department shall submit a report to the Governor, the President of the Senate, and the Speaker of the House of Representatives containing recommendations, including draft legislation, for any modifications to the process for allocating total maximum daily loads, including the relationship between allocations and the watershed or basin management planning process. Such recommendations shall be developed by the department in cooperation with a technical advisory committee which includes representatives of affected parties, environmental organizations, water management districts, and other appropriate local, state, and federal government agencies. The technical advisory committee shall also include such members as may be designated by the President of the Senate and the Speaker of the House of Representatives. The total maximum daily load calculations and allocations for each water body or water body segment shall be adopted by rule by the secretary pursuant to ss. 120.536(1), 120.54, and 403.805. The rules adopted pursuant to this paragraph shall not be subject to approval by the Environmental Regulation Commission. As part of the rule development process, the department shall hold at least one public workshop in the vicinity of the water body or water body segment for which the total maximum daily load is being developed. Notice of the public workshop shall be published not less than 5 days nor more than 15 days before the public workshop in a newspaper of general circulation in the county or counties containing the water bodies or water body segments for which the total maximum daily load calculation and allocation are being developed. IMPLEMENTATION OF TOTAL MAXIMUM DAILY LOADS.-- The department shall be the lead agency in coordinating the implementation of the total maximum daily loads through water quality protection programs. Application of a total maximum daily load by a water management district shall be consistent with this section and shall not require the issuance of an order or a separate action pursuant to s. 120.536(1) or s. 120.54 for adoption of the calculation and allocation previously established by the department. Such programs may include, but are not limited to: Permitting and other existing regulatory programs; Nonregulatory and incentive-based programs, including best management practices, cost sharing, waste minimization, pollution prevention, and public education; Other water quality management and restoration activities, for example surface water improvement and management plans approved by water management districts under s. 373.456 or watershed or basin management plans developed pursuant to this subsection; Pollutant trading or other equitable economically based agreements; Public works including capital facilities; or Land acquisition. In developing and implementing the total maximum daily load for a water body, the department, or the department in conjunction with a water management district, may develop a watershed or basin management plan that addresses some or all of the watersheds and basins tributary to the water body. These plans will serve to fully integrate the management strategies available to the state for the purpose of implementing the total maximum daily loads and achieving water quality restoration. The watershed or basin management planning process is intended to involve the broadest possible range of interested parties, with the objective of encouraging the greatest amount of cooperation and consensus possible. The department or water management district shall hold at least one public meeting in the vicinity of the watershed or basin to discuss and receive comments during the planning process and shall otherwise encourage public participation to the greatest practical extent. Notice of the public meeting shall be published in a newspaper of general circulation in each county in which the watershed or basin lies not less than 5 days nor more than 15 days before the public meeting. A watershed or basin management plan shall not supplant or otherwise alter any assessment made under s. 403.086(3) and (4), or any calculation or allocation made under s. 403.086(6). The department, in cooperation with the water management districts and other interested parties, as appropriate, may develop suitable interim measures, best management practices, or other measures necessary to achieve the level of pollution reduction established by the department for nonagricultural nonpoint pollutant sources in allocations developed pursuant to paragraph (6)(b). These practices and measures may be adopted by rule by the department and the water management districts pursuant to ss. 120.536(1) and 120.54, and may be implemented by those parties responsible for nonagricultural nonpoint pollutant sources and the department and the water management districts shall assist with implementation. Where interim measures, best management practices, or other measures are adopted by rule, the effectiveness of such practices in achieving the levels of pollution reduction established in allocations developed by the department pursuant to paragraph (6)(b) shall be verified by the department. Implementation, in accordance with applicable rules, of practices that have been verified by the department to be effective at representative sites shall provide a presumption of compliance with state water quality standards and release from the provisions of s.376.307(5) for those pollutants addressed by the practices, and the department is not authorized to institute proceedings against the owner of the source of pollution to recover costs or damages associated with the contamination of surface or ground water caused by those pollutants. Such rules shall also incorporate provisions for a notice of intent to implement the practices and a system to assure the implementation of the practices, including recordkeeping requirements. Where water quality problems are detected despite the appropriate implementation, operation, and maintenance of best management practices and other measures according to rules adopted under this paragraph, the department or the water management districts shall institute a reevaluation of the best management practice or other measures. 1. The Department of Agriculture and Consumer Services may develop and adopt by rule pursuant to ss. 120.536(1) and 120.54 suitable interim measures, best management practices, or other measures necessary to achieve the level of pollution reduction established by the department for agricultural pollutant sources in allocations developed pursuant to paragraph (6)(b). These practices and measures may be implemented by those parties responsible for agricultural pollutant sources and the department, the water management districts, and the Department of Agriculture and Consumer Services shall assist with implementation. Where interim measures, best management practices, or other measures are adopted by rule, the effectiveness of such practices in achieving the levels of pollution reduction established in allocations developed by the department pursuant to paragraph (6)(b) shall be verified by the department. Implementation, in accordance with applicable rules, of practices that have been verified by the department to be effective at representative sites shall provide a presumption of compliance with state water quality standards and release from the provisions of s.376.307(5) for those pollutants addressed by the practices, and the department is not authorized to institute proceedings against the owner of the source of pollution to recover costs or damages associated with the contamination of surface or ground water caused by those pollutants. In the process of developing and adopting rules for interim measures, best management practices, or other measures, the Department of Agriculture and Consumer Services shall consult with the department, the Department of Health, the water management districts, representatives from affected farming groups, and environmental group representatives. Such rules shall also incorporate provisions for a notice of intent to implement the practices and a system to assure the implementation of the practices, including recordkeeping requirements. Where water quality problems are detected despite the appropriate implementation, operation, and maintenance of best management practices and other measures according to rules adopted under this paragraph, the Department of Agriculture and Consumer Services shall institute a reevaluation of the best management practice or other measure. 2. Individual agricultural records relating to processes or methods of production, or relating to costs of production, profits, or other financial information which are otherwise not public records, which are reported to the Department of Agriculture and Consumer Services pursuant to this paragraph or pursuant to any rule adopted pursuant to this paragraph shall be confidential and exempt from s. 119.07(1) and s. 24(a), Art. I of the State Constitution. Upon request of the department or any water management district, the Department of Agriculture and Consumer Services shall make such individual agricultural records available to that agency, provided that the confidentiality specified by this subparagraph for such records is maintained. This subparagraph is subject to the Open Government Sunset Review Act of 1995 in accordance with s. 119.15, and shall stand repealed on October 2, 2006, unless reviewed and saved from repeal through reenactment by the Legislature. The provisions of paragraphs (c) and (d) shall not preclude the department or water management district from requiring compliance with water quality standards or with current best management practice requirements set forth in any applicable regulatory program authorized by law for the purpose of protecting water quality. Additionally, paragraphs (c) and (d) are applicable only to the extent that they do not conflict with any rules promulgated by the department that are necessary to maintain a federally delegated or approved program. RULES.-- The department is authorized to adopt rules pursuant to ss. 120.536(1) and 120.54 for: Delisting water bodies or water body segments from the list developed under subsection (4) pursuant to the guidance under subsection (5); Administration of funds to implement the total maximum daily load program; Procedures for pollutant trading among the pollutant sources to a water body or water body segment, including a mechanism for the issuance and tracking of pollutant credits. Such procedures may be implemented through permits or other authorizations and must be legally binding. No rule implementing a pollutant trading program shall become effective prior to review and ratification by the Legislature; and The total maximum daily load calculation in accordance with paragraph (6)(a) immediately upon the effective date of this act, for those eight water segments within Lake Okeechobee proper as submitted to the United States Environmental Protection Agency pursuant to subsection (2). APPLICATION.-- The provisions of this section are intended to supplement existing law, and nothing in this section shall be construed as altering any applicable state water quality standards or as restricting the authority otherwise granted to the department or a water management district under this chapter or chapter 373. The exclusive means of state implementation of s. 303(d) of the Clean Water Act, Pub. L. No. 92-500, 33 U.S.C. ss. 1251 et seq. shall be in accordance with the identification, assessment, calculation and allocation, and implementation provisions of this section. CONSTRUCTION.-- Nothing in this section shall be construed as limiting the applicability or consideration of any mixing zone, variance, exemption, site specific alternative criteria, or other moderating provision. IMPLEMENTATION OF ADDITIONAL PROGRAMS.-- The department shall not implement, without prior legislative approval, any additional regulatory authority pursuant to s. 303(d) of the Clean Water Act or 40 C.F.R. part 130, if such implementation would result in water quality discharge regulation of activities not currently subject to regulation. In order to provide adequate due process while ensuring timely development of total maximum daily loads, proposed rules and orders authorized by this act shall be ineffective pending resolution of a s. 120.54(3), s. 120.56, s. 120.569, or s. 120.57 administrative proceeding. However, the department may go forward prior to resolution of such administrative proceedings with subsequent agency actions authorized by subsections (2)-(6), provided that the department can support and substantiate those actions using the underlying bases for the rules or orders without the benefit of any legal presumption favoring, or in deference to, the challenged rules or orders. Key Provisions of Law Referenced in Section 403.067, Florida Statutes Section 403.021, Florida Statutes Section 403.021, Florida Statutes, which is referenced in Subsection (1) of Section 403.067, Florida Statutes, provides, in pertinent part, as follows: The pollution of the air and waters of this state constitutes a menace to public health and welfare; creates public nuisances; is harmful to wildlife and fish and other aquatic life; and impairs domestic, agricultural, industrial, recreational, and other beneficial uses of air and water. It is declared to be the public policy of this state to conserve the waters of the state and to protect, maintain, and improve the quality thereof for public water supplies, for the propagation of wildlife and fish and other aquatic life, and for domestic, agricultural, industrial, recreational, and other beneficial uses and to provide that no wastes be discharged into any waters of the state without first being given the degree of treatment necessary to protect the beneficial uses of such water. * * * It is hereby declared that the prevention, abatement, and control of the pollution of the air and waters of this state are affected with a public interest, and the provisions of this act are enacted in the exercise of the police powers of this state for the purpose of protecting the health, peace, safety, and general welfare of the people of this state. The Legislature finds and declares that control, regulation, and abatement of the activities which are causing or may cause pollution of the air or water resources in the state and which are or may be detrimental to human, animal, aquatic, or plant life, or to property, or unreasonably interfere with the comfortable enjoyment of life or property be increased to ensure conservation of natural resources; to ensure a continued safe environment; to ensure purity of air and water; to ensure domestic water supplies; to ensure protection and preservation of the public health, safety, welfare, and economic well-being; to ensure and provide for recreational and wildlife needs as the population increases and the economy expands; and to ensure a continuing growth of the economy and industrial development. The Legislature further finds and declares that: Compliance with this law will require capital outlays of hundreds of millions of dollars for the installation of machinery, equipment, and facilities for the treatment of industrial wastes which are not productive assets and increased operating expenses to owners without any financial return and should be separately classified for assessment purposes. Industry should be encouraged to install new machinery, equipment, and facilities as technology in environmental matters advances, thereby improving the quality of the air and waters of the state and benefiting the citizens of the state without pecuniary benefit to the owners of industries; and the Legislature should prescribe methods whereby just valuation may be secured to such owners and exemptions from certain excise taxes should be offered with respect to such installations. Facilities as herein defined should be classified separately from other real and personal property of any manufacturing or processing plant or installation, as such facilities contribute only to general welfare and health and are assets producing no profit return to owners. In existing manufacturing or processing plants it is more difficult to obtain satisfactory results in treating industrial wastes than in new plants being now planned or constructed and that with respect to existing plants in many instances it will be necessary to demolish and remove substantial portions thereof and replace the same with new and more modern equipment in order to more effectively treat, eliminate, or reduce the objectionable characteristics of any industrial wastes and that such replacements should be classified and assessed differently from replacements made in the ordinary course of business. * * * It is the policy of the state to ensure that the existing and potential drinking water resources of the state remain free from harmful quantities of contaminants. The department, as the state water quality protection agency, shall compile, correlate, and disseminate available information on any contaminant which endangers or may endanger existing or potential drinking water resources. It shall also coordinate its regulatory program with the regulatory programs of other agencies to assure adequate protection of the drinking water resources of the state. It is the intent of the Legislature that water quality standards be reasonably established and applied to take into account the variability occurring in nature. The department shall recognize the statistical variability inherent in sampling and testing procedures that are used to express water quality standards. The department shall also recognize that some deviations from water quality standards occur as the result of natural background conditions. The department shall not consider deviations from water quality standards to be violations when the discharger can demonstrate that the deviations would occur in the absence of any human-induced discharges or alterations to the water body. Rule Chapter 62-302, Florida Administrative Code Rule Chapter 62-302, Florida Administrative Code, which is referenced in Subsection (3)(b) of Section 447.067, Florida Statutes, contains Florida's "[s]urface water quality standards." Rule 62-302.300, Florida Administrative Code, is entitled, "Findings, Intent, and Antidegradation Policy for Surface Water Quality," and provides as follows: Article II, Section 7 of the Florida Constitution requires abatement of water pollution and conservation and protection of Florida's natural resources and scenic beauty. Congress, in Section 101(a)(2) of the Federal Water Pollution Control Act, as amended,[14] declares that achievement by July 1, 1983, of water quality sufficient for the protection and propagation[15] of fish, shellfish, and wildlife, as well as for recreation in and on the water, is an interim goal to be sought whenever attainable. Congress further states, in Section 101(a)(3), that it is the national policy that the discharge of toxic pollutants in toxic amounts be prohibited. The present and future most beneficial uses of all waters of the State have been designated by the Department by means of the Classification system set forth in this Chapter pursuant to Subsection 403.061(10), F.S.[16] Water quality standards[17] are established by the Department to protect these designated uses.[18] Because activities outside the State sometimes cause pollution[19] of Florida's waters, the Department will make every reasonable effort to have such pollution abated. Water quality standards apply equally to and shall be uniformly enforced in both the public and private sector. Public interest shall not be construed to mean only those activities conducted solely to provide facilities or benefits to the general public. Private activities conducted for private purposes may also be in the public interest. The Commission, recognizing the complexity of water quality management and the necessity to temper regulatory actions with the technological progress and the social and economic well-being of people, urges, however, that there be no compromise where discharges of pollutants constitute a valid hazard to human health. The Commission requests that the Secretary seek and use the best environmental information available when making decisions on the effects of chronically and acutely toxic substances and carcinogenic, mutagenic, and teratogenic substances. Additionally, the Secretary is requested to seek and encourage innovative research and developments in waste treatment alternatives that might better preserve environmental quality or at the same time reduce the energy and dollar costs of operation. The criteria set forth in this Chapter are minimum levels which are necessary to protect the designated uses of a water body. It is the intent of this Commission that permit applicants should not be penalized due to a low detection limit associated with any specific criteria. (10)(a) The Department's rules that were adopted on March 1, 1979 regarding water quality standards are designed to protect the public health or welfare and to enhance the quality of waters of the State. They have been established taking into consideration the use and value of waters of the State for public water supplies, propagation of fish and wildlife, recreational purposes, and agricultural, industrial, and other purposes, and also taking into consideration their use and value for navigation. Under the approach taken in the formulation of the rules adopted in this proceeding: The Department's rules that were adopted on March 1, 1979 regarding water quality standards are based upon the best scientific knowledge related to the protection of the various designated uses of waters of the State; and The mixing zone,[20] zone of discharge, site specific alternative criteria, exemption, and equitable allocation provisions are designed to provide an opportunity for the future consideration of factors relating to localized situations which could not adequately be addressed in this proceeding, including economic and social consequences, attainability, irretrievable conditions, natural background,[21] and detectability. This is an even-handed and balanced approach to attainment of water quality objectives. The Commission has specifically recognized that the social, economic and environmental costs may, under certain special circumstances, outweigh the social, economic and environmental benefits if the numerical criteria are enforced statewide. It is for that reason that the Commission has provided for mixing zones, zones of discharge, site specific alternative criteria, exemptions and other provisions in Chapters 62-302, 62-4, and 62-6, F.A.C. Furthermore, the continued availability of the moderating provisions is a vital factor providing a basis for the Commission's determination that water quality standards applicable to water classes in the rule are attainable taking into consideration environmental, technological, social, economic and institutional factors. The companion provisions of Chapters 62-4 and 62-6, F.A.C., approved simultaneously with these Water Quality Standards are incorporated herein by reference as a substantive part of the State's comprehensive program for the control, abatement and prevention of water pollution. Without the moderating provisions described in (b)2. above, the Commission would not have adopted the revisions described in (b)1. above nor determined that they are attainable as generally applicable water quality standards. Section 403.021, Florida Statutes, declares that the public policy of the State is to conserve the waters of the State to protect, maintain, and improve the quality thereof for public water supplies, for the propagation of wildlife, fish and other aquatic life, and for domestic, agricultural, industrial, recreational, and other beneficial uses. It also prohibits the discharge of wastes into Florida waters without treatment necessary to protect those beneficial uses of the waters. The Department shall assure that there shall be achieved the highest statutory and regulatory requirements for all new and existing point sources, and all cost- effective and reasonable best management practices for nonpoint source control. For the purposes of this rule, highest statutory and regulatory requirements for new and existing point sources are those which can be achieved through imposition of effluent limits required under Sections 301(b) and 306 of the Federal Clean Water Act (as amended in 1987) and Chapter 403, F.S. For the purposes of this rule, cost-effective and reasonable best management practices for nonpoint source control are those nonpoint source controls authorized under Chapters 373 and 403, F.S., and Department rules. The Department finds that excessive nutrients (total nitrogen and total phosphorus) constitute one of the most severe water quality problems facing the State. It shall be the Department's policy to limit the introduction of man-induced nutrients into waters of the State. Particular consideration shall be given to the protection from further nutrient enrichment of waters which are presently high in nutrient concentrations or sensitive to further nutrient concentrations and sensitive to further nutrient loadings. Also, particular consideration shall be given to the protection from nutrient enrichment of those waters presently containing very low nutrient concentrations: less than 0.3 milligrams per liter total nitrogen or less than 0.04 milligrams per liter total phosphorus. Existing uses and the level of water quality necessary to protect the existing uses shall be fully maintained and protected. Such uses may be different or more extensive than the designated use. Pollution which causes or contributes to new violations of water quality standards or to continuation of existing violations is harmful to the waters of this State and shall not be allowed. Waters having water quality below the criteria established for them shall be protected and enhanced. However, the Department shall not strive to abate natural conditions. If the Department finds that a new or existing discharge will reduce the quality of the receiving waters below the classification established for them or violate any Department rule or standard, it shall refuse to permit the discharge. If the Department finds that a proposed new discharge or expansion of an existing discharge will not reduce the quality of the receiving waters below the classification established for them, it shall permit the discharge if such degradation is necessary or desirable under federal standards and under circumstances which are clearly in the public interest, and if all other Department requirements are met. Projects permitted under Part IV of Chapter 373, F.S., shall be considered in compliance with this subsection if those projects comply with the requirements of subsection 373.414(1), F.S.; also projects permitted under the grandfather provisions of Sections 373.414(11) through (16), F.S., or permitted under Section 373.4145, F.S., shall be considered in compliance with this subsection if those projects comply with the requirements of Rule 62-312.080(2), F.A.C. (18)(a) Except as provided in subparagraphs (b) and (c) of this paragraph, an applicant for either a general permit or renewal of an existing permit for which no expansion of the discharge is proposed is not required to show that any degradation from the discharge is necessary or desirable under federal standards and under circumstances which are clearly in the public interest. If the Department determines that the applicant has caused degradation of water quality over and above that allowed through previous permits issued to the applicant, then the applicant shall demonstrate that this lowering of water quality is necessary or desirable under federal standards and under circumstances which are clearly in the public interest. These circumstances are limited to cases where it has been demonstrated that degradation of water quality is occurring due to the discharge. If the new or expanded discharge was initially permitted by the Department on or after October 4, 1989, and the Department determines that an antidegradation analysis was not conducted, then the applicant seeking renewal of the existing permit shall demonstrate that degradation from the discharge is necessary or desirable under federal standards and under circumstances which are clearly in the public interest. Rule 62-302.400, Florida Administrative Code, classifies all surface waters of the state "according to designated uses." The rule provides for five classifications: Class I ("Potable Water Supplies"); Class II ("Shellfish Propagation or Harvesting"); Class III ("Recreation, Propagation of a Healthy, Well-Balanced Population of Fish and Wildlife": Fresh and Marine); Class IV ("Agricultural Water Supplies"); and Class V ("Navigation, Utility and Industrial Use").22 See Rule 62-302.400(1), Florida Administrative Code. These "[w]ater quality classifications are arranged in order of degree of protection required, with Class I water having generally the most stringent water quality criteria23 and Class V the least. However, Class I, II, and III surface waters share water quality criteria established to protect recreation and the propagation and maintenance of a healthy well-balanced population of fish and wildlife." Rule 62-302.400(4), Florida Administrative Code. Waters designated as "Outstanding Florida Waters and Outstanding National Resource Waters" are given "special protection." See Rule 62-302.700(1) and (7), Florida Administrative Code ("It shall be the Department policy to afford the highest protection to Outstanding Florida Waters and Outstanding National Resource Waters. No degradation of water quality, other than that allowed in Rule 62-4.242(2) and (3), F.A.C., is to be permitted in Outstanding Florida Waters and Outstanding National Resource Waters, respectively, notwithstanding any other Department rules that allow water quality lowering. . . . The policy of this section shall be implemented through the permitting process pursuant to Section 62-4.242, F.A.C.").24 According to Subsection (5) of Rule 62-302.400, Florida Administrative Code, Criteria applicable to a classification are designed to maintain the minimum conditions necessary to assure the suitability of water for the designated use of the classification. In addition, applicable criteria are generally adequate to maintain minimum conditions required for the designated uses of less stringently regulated classifications. Therefore, unless clearly inconsistent with the criteria applicable, the designated uses of less stringently regulated classifications shall be deemed to be included within the designated uses of more stringently regulated classifications. "The specific water quality criteria corresponding to each surface water classification are listed in Rules 62-302.500 and 62-302.530," Florida Administrative Code. Rule 62- 302.400(3), Florida Administrative Code. Subsection (1) of Rule 62-302.500, Florida Administrative Code, sets forth what are known as the "free froms." It provides as follows: Minimum Criteria. All surface waters of the State shall at all places and at all times be free from: Domestic, industrial, agricultural, or other man-induced non-thermal components of discharges which, alone or in combination with other substances or in combination with other components of discharges (whether thermal or non-thermal): Settle to form putrescent deposits or otherwise create a nuisance; or Float as debris, scum, oil, or other matter in such amounts as to form nuisances; or Produce color, odor, taste, turbidity, or other conditions in such degree as to create a nuisance; or Are acutely toxic; or Are present in concentrations which are carcinogenic, mutagenic, or teratogenic to human beings or to significant, locally occurring, wildlife or aquatic species, unless specific standards are established for such components in Rules 62-302.500(2) or 62-302.530; or Pose a serious danger to the public health, safety, or welfare. Thermal components of discharges which, alone, or in combination with other discharges or components of discharges (whether thermal or non-thermal): Produce conditions so as to create a nuisance; or Do not comply with applicable provisions of Rule 62-302.500(3), F.A.C. Silver in concentrations above 2.3 micrograms/liter in predominantly marine waters. Rule 62-302.530, Florida Administrative Code, has a table that contains both numeric and narrative surface water quality criteria to be applied except within zones of mixing. The left-hand column of the Table is a list of constituents [or parameters] for which a surface water criterion exists. The headings for the water quality classifications are found at the top of the Table. Applicable criteria lie within the Table. The individual criteria should be read in conjunction with other provisions in water quality standards, including Rules 62- 302.500 and 62-302.510, F.A.C. The criteria contained in Rules 62-302.500 or 62-302.510 also apply to all waters unless alternative or more stringent criteria are specified in Rule 62-302.530, F.A.C. Unless otherwise stated, all criteria express the maximum not to be exceeded at any time. In some cases, there are separate or additional limits, such as annual average criteria, which apply independently of the maximum not to be exceeded at any time. The following are the specific parameters listed in the table: Alkalinity; Aluminum; Ammonia (un-ionized); Antimony; Arsenic (total and trivalent); Bacteriological Quality (Fecal Coliform Bacteria); Bacteriological Quality (Total Coliform Bacteria); Barium; Benzene; Beryllium; Biological Integrity; BOD (Biochemical Oxygen Demand); Bromine (free molecular); Cadmium; Carbon Tetrachloride; Chlorides; Chlorine (total residual); Chromium (trivalent and hexavalent); Chronic Toxicity; Color; Conductance (specific); Copper; Cyanide; Detergents; 1,1- Dichloroethylene (1,1-di-chloroethene); Dichloromethane (methylene chloride); 2,4-Dinitrotoluene; Dissolved Oxygen; Dissolved Solids; Fluorides; Halomethanes; Hexachlorobutadiene; Iron; Lead; Manganese; Mercury; Nickel; Nitrate; Nuisance Species;25 Nutrients;26 Odor; Oils and Greases; Pesticides and Herbicides (2,4,5-TP; 2-4-D; Aldrin; Betahexachlorocyclohexane; Chlordane; DDT; Demeton; Dieldrin; Endosulfan; Endrin: Guthion; Heptachlor; Lindane; Malathion; Methoxychlor; Mirex; Parathion; Toxaphene); pH; Phenolic Compounds; Phosphorous (Elemental); Polycyclic Aromatic Hydrocarbons; Radioactive Substances; Selenium; Silver; 1,1,2,2-Tetrachloroethane; Tetrachloroethylene; Thallium; Total Dissolved Gases; Transparency; Trichloroeylene (trichloroethene); Turbidity; and Zinc. Rule 62-302.800, Florida Administrative Code, provides for the establishment of "[s]ite [s]pecific [a]lternative [c]riteria" where a water body, or portion thereof, does "not meet a particular ambient water quality criterion specified for its classification, due to natural background conditions or man- induced conditions which cannot be controlled or abated."27 Section 303(d) of the Clean Water Act Section 303(d) of the Clean Water Act (33 U.S.C. Section 1313(d)), which is referenced in Subsections (1), (2), (9), and (11) of Section 447.067, Florida Statutes, provides as follows: Identification of areas with insufficient controls; maximum daily load; certain effluent limitations revision (1)(A) Each State shall identify those waters within its boundaries for which the effluent limitations required by section 1311(b)(1)(A) and section 1311(b)(1)(B) of this title are not stringent enough to implement any water quality standard applicable to such waters. The State shall establish a priority ranking for such waters, taking into account the severity of the pollution and the uses to be made of such waters. Each State shall identify those waters or parts thereof within its boundaries for which controls on thermal discharges under section 1311 of this title are not stringent enough to assure protection and propagation of a balanced indigenous population of shellfish, fish, and wildlife. Each State shall establish for the waters identified in paragraph (1)(A) of this subsection, and in accordance with the priority ranking, the total maximum daily load, for those pollutants which the Administrator identifies under section 1314(a)(2) of this title as suitable for such calculation. Such load shall be established at a level necessary to implement the applicable water quality standards with seasonal variations and a margin of safety which takes into account any lack of knowledge concerning the relationship between effluent limitations and water quality. Each State shall submit to the Administrator from time to time, with the first such submission not later than one hundred and eighty days after the date of publication of the first identification of pollutants under section 1314(a)(2)(D) of this title, for his approval the waters identified and the loads established under paragraphs (1)(A), (1)(B), (1)(C), and (1)(D) of this subsection. The Administrator shall either approve or disapprove such identification and load not later than thirty days after the date of submission. If the Administrator approves such identification and load, such State shall incorporate them into its current plan under subsection (e) of this section. If the Administrator disapproves such identification and load, he shall not later than thirty days after the date of such disapproval identify such waters in such State and establish such loads for such waters as he determines necessary to implement the water quality standards applicable to such waters and upon such identification and establishment the State shall incorporate them into its current plan under subsection (e) of this section. For the specific purpose of developing information, each State shall identify all waters within its boundaries which it has not identified under paragraph (1)(A) and (1)(B) of this subsection and estimate for such waters the total maximum daily load with seasonal variations and margins of safety, for those pollutants which the Administrator identifies under section 1314(a)(2) of this title as suitable for such calculation and for thermal discharges, at a level that would assure protection and propagation of a balanced indigenous population of fish, shellfish and wildlife. Limitations on revision of certain effluent limitations Standard not attained For waters identified under paragraph (1)(A) where the applicable water quality standard has not yet been attained, any effluent limitation based on a total maximum daily load or other waste load allocation established under this section may be revised only if (i) the cumulative effect of all such revised effluent limitations based on such total maximum daily load or waste load allocation will assure the attainment of such water quality standard, or (ii) the designated use which is not being attained is removed in accordance with regulations established under this section. Standard attained For waters identified under paragraph (1)(A) where the quality of such waters equals or exceeds levels necessary to protect the designated use for such waters or otherwise required by applicable water quality standards, any effluent limitation based on a total maximum daily load or other waste load allocation established under this section, or any water quality standard established under this section, or any other permitting standard may be revised only if such revision is subject to and consistent with the antidegradation policy established under this section. Development of Proposed Rule Chapter 62-303, Florida Administrative Code The rule development process that culminated in the adoption of proposed Rule Chapter 62-303, Florida Administrative Code, began shortly after the enactment of Chapter 99-223, Laws of Florida, when the Department decided, consistent with its routine practice in complex rulemaking cases, to form a technical advisory committee (TAC) to assist the Department in developing an "identification of impaired surface waters" rule by rendering advice to the Department concerning technical and scientific matters.28 The Department solicited nominations for TAC membership from stakeholder groups, but ultimately rejected the nominations it received and instead selected individuals it believed were best qualified to contribute based upon their expertise (in areas including water quality monitoring, water quality chemistry, water quality modeling, estuarine ecology, wetland ecology, analytical chemistry, statistics, bioassessment procedures, limnology, coastal ecology, fish biology, and hydrology). The first TAC meeting was held August 12, 1999. There were 12 subsequent TAC meetings, the last two of which were held on August 4, 2000, and August 28, 2000. The TAC meetings were held in various locations throughout the state (Pensacola, Tallahassee, Jacksonville, Gainesville, Orlando, Tampa, St. Petersburg, and West Palm Beach) and were open to public, with members of the public able to make comments. All 13 TAC meetings were noticed in the Florida Administrative Weekly. The TAC meetings were chaired by Mr. Joyner, who was the Department employee primarily responsible for drafting an "identification of impaired surface waters" rule. Mr. Joyner emphasized to the TAC members that their role was simply to give advice and make recommendations to the Department and that their advice and recommendations might not be followed. As it turned out, there were several instances where the Department rejected a TAC recommendation. In addition to seeking the advice of experts on technical and scientific matters, the Department wanted to hear from stakeholders regarding policy issues. Towards that end, it took steps to establish a Policy Advisory Committee (PAC). An organizational meeting of the PAC was held on March 24, 2000, in Tallahassee, the day after the seventh TAC meeting (which was also held in Tallahassee). After being told about the government in the sunshine and public records laws with which they would have to comply as PAC members, "no one wanted to be on the PAC." The consensus of those present was to "just have public meetings [to elicit stakeholder input] and not have a formal PAC." The Department acted accordingly. Following this March 24, 2000, meeting, the Department abandoned its efforts to form a PAC and instead held four public meetings to obtain input from the public regarding policy questions involved in crafting an "identification of impaired surface waters" rule. The last two of these public meetings were combined with the last two TAC meetings (held on August 4, 2000, and August 28, 2000). Each of the five "policy" public meetings held by the Department (including the March 24, 2000, PAC organizational meeting) were noticed in the Florida Administrative Weekly. The Department also held two rule development workshops (one on September 7, 2000, and the other on December 7, 2000), both of which were also noticed in the Florida Administrative Weekly. Between the time these two rule development workshops were held, Mr. Joyner met with representatives of regulated interests and the environmental community to discuss their thoughts regarding what should be included in an "identification of impaired surface waters" rule. Throughout the rule development process, the Department also received and considered written comments from interested persons. Information about the rule development process was posted on the Department's web site for the public to read. The Department e-mailed approximately 350 persons (whose names were on a list of interested persons compiled by the Department) to notify them in advance of any meetings and workshops on proposed Rule Chapter 62-303, Florida Administrative Code. Proposed Rule Chapter 62-303, Florida Administrative Code, underwent numerous revisions during the rule development process. Whenever a revised version of the proposed rule chapter was prepared, the Department sent a copy of it, via e-mail, to the persons on the Department's 350 "interested persons" e-mail list. Changes to proposed Rule Chapter 62-303, Florida Administrative Code, were made not only in response to comments made by members of the TAC and stakeholders, but also in response to comments made by staff of the Region IV office of the United States Environmental Protection Agency (EPA), with whom Department staff had extensive discussions regarding the proposed rule chapter. The Environmental Regulation Commission (ERC) "exercise[s] the standard-setting authority of the [D]epartment."29 In March of 2001, approximately 19 months after the first TAC meeting, the Department was ready to present its most recent version of proposed Rule Chapter 62-303, Florida Administrative Code, to the ERC for adoption. Accordingly, it published a Notice of Proposed Rulemaking in the March 23, 2001 (Volume 27, Number 12) edition of the Florida Administrative Weekly announcing that a hearing on the proposed rule chapter would be held before the ERC on April 26, 2001. The Notice contained the complete text of the proposed rule chapter, as well as the following statement of “[p]urpose, effect, and summary”: The purpose of the proposed new rule is to establish a methodology to identify impaired waters that will be included on the State's verified list of impaired waters, for which the Department will calculate Total Maximum Daily Loads, pursuant to subsection 403.067(4), Florida Statutes (F.S.), and which will be submitted to the United States Environmental Protection Agency pursuant to subparagraphs 303(d)(1)(A) and 303(d)(1)(C) of the Clean Water Act. As directed by 403.067, F.S., the development of the State's 303(d) list will be a two-step process; waters will first be identified as potentially impaired and then any impairment will be verified before listing the water. The rule implements this statutory direction by providing a methodology to identify surface waters of the state that will be included on a "planning list" of waters. Pursuant to subsection 403.067(2) and (3), F.S., the Department will evaluate the data used to place these waters on the planning list, verify that the data meet quality assurance and data sufficiency requirements of the "verified list," and collect additional data, as needed, to complete the assessment. The rule also provides information about the listing cycle, the format of the verified list, and delisting procedures. At the ERC's regularly scheduled March 29, 2001, meeting, Mr. Joyner formally briefed the ERC on the status of the rule development process (as he had previously done at ERC's regularly scheduled meetings on June 29, 2000, August 24, 2000, December 5, 2000, and January 25, 2001). At the March 29, 2001, meeting, Mr. Joyner went through the proposed rule chapter with the ERC "paragraph by paragraph." As noted above, prior to the scheduled April 26, 2001, ERC hearing, petitions challenging the proposed rule chapter (as published in the March 23, 2001, edition of the Florida Administrative Weekly) were filed with the Division by Petitioner Lane (on April 10, 2001) and by all Joint Petitioners excluding Save Our Suwannee, Inc. (on April 13, 2001). On April 21, 2001, all Joint Petitioners excluding Save Our Suwannee, Inc., filed a Request with ERC asking: that rulemaking proceedings regarding proposed Rule 62-303 be conducted under the provisions of Sections 120.569 and 120.57, Florida Statutes, as to all parties, or alternatively at least to the six petitioners; that the evidentiary processes involved under the provisions of Sections 120.569 and 120.57, Florida Statutes, be combined with the already pending DOAH proceedings of all parties, or at least the six petitioners; and that rulemaking proceedings, as to proposed Rule 62-303, be suspended pending completion of the evidentiary processes before DOAH as well as the DOAH ruling on the pending petitions, as to all parties or at least the six petitioners. The Request was considered and denied by the ERC at the outset of its hearing on the proposed rule chapter, which was held as scheduled on April 26, 2001. That same day, the ERC issued a written order denying the Request, which read, in pertinent part as follows: But for their request to combine the requested evidentiary proceeding with the existing rule challenges pending before DOAH, Petitioners have requested conversion of the instant rulemaking proceeding to an evidentiary hearing or "draw out." A draw out is authorized under proper circumstances by Section 120.54(3)(c)2, Florida Statutes, which states: "Rulemaking proceedings shall be governed solely by the provisions of this section unless a person timely asserts that the person's substantial interests will be affected in the proceeding and affirmatively demonstrates to the agency that the proceeding does not provide adequate opportunity to protect those interests. If the agency determines that the rulemaking proceeding is not adequate to protect the person's interests, it shall suspend the rulemaking proceeding and convene a separate proceeding under the provisions of ss. 120.569 and 120.57. Similarly situated persons may be requested to join and participate in the separate proceeding. Upon conclusion of the separate proceeding, the rulemaking proceeding shall be resumed." A participant in the rulemaking proceeding who requests such relief is asking to "draw out" of the rulemaking proceeding and for the agency to afford the party an evidentiary hearing in lieu thereof.[30] A copy of each of the six petitions filed by the parties with DOAH was attached to the joint notice now before the Commission. But for minor variations in allegations to establish standing, each of the six petitions sets out seventeen (17) counts with each count asserting that a particular provision, or provisions, of proposed Rule 62-303 is an invalid exercise of delegated legislative authority or otherwise a violation of Section 403.067, F.S., or the federal Clean Water Act. None of the individual petitions, or the joint notice, demonstrate that the pending rulemaking proceeding fails to protect the petitioners' substantial interests, nor have petitioners raised any factual issues that would require a separate evidentiary hearing beyond the scope of the DOAH proceedings already pending. Under these circumstances, Section 120.56(2)(b), F.S., specifically allows an agency to proceed with all other steps in the rulemaking process, except for final adoption, while a DOAH rule challenge is pending.[31] In view of the foregoing, and in exercising its discretion as afforded by Section 120.54(3)(c)2., F.S., the Commission has determined that the rulemaking proceeding adequately protects the interests asserted by each of the six petitioners who joined in the joint notice as filed April 20th, 2001. Accordingly, the petitioners' joint request for relief therein is denied. The version of the proposed rule chapter published in the March 23, 2001, edition of the Florida Administrative Weekly, with some modifications, was adopted by the ERC at its April 26, 2001, meeting (at which members of the public were given the opportunity to comment prior to ERC deliberation). The modifications were noticed in a Notice of Change published in the May 11, 2001, edition (Volume 27, Number 19) of the Florida Administrative Weekly. Contents of the ERC-Adopted Version of Proposed Rule Chapter 62- 303, Florida Administrative Code Proposed Rule Chapter 62-303, Florida Administrative Code, is entitled, "Identification of Impaired Surface Waters." It is divided into four parts. Part I: Overview Part I of proposed Rule Chapter 62-303, Florida Administrative Code, contains the following "general" provisions: Proposed Rules 62-303.100, 62-303.150, and 62- 303.200, Florida Administrative Code. Part I: Proposed Rule 62-303.100, Florida Administrative Code Proposed Rule 62-303.100, Florida Administrative Code, is entitled, "Scope and Intent." It provides an overview of the proposed rule chapter and reads as follows: This chapter establishes a methodology to identify surface waters of the state that will be included on the state's planning list of waters that will be assessed pursuant to subsections 403.067(2) and (3), Florida Statutes (F.S.). It also establishes a methodology to identify impaired waters that will be included on the state's verified list of impaired waters, for which the Department will calculate Total Maximum Daily Loads (TMDLs), pursuant to subsection 403.067(4) F.S., and which will be submitted to the United States Environmental Protection Agency (EPA) pursuant to paragraph 303(d)(1) of the Clean Water Act (CWA). Subsection 303(d) of the CWA and section 403.067, F.S., describe impaired waters as those not meeting applicable water quality standards, which is a broad term that includes designated uses, water quality criteria, the Florida antidegradation policy, and moderating provisions. However, as recognized when the water quality standards were adopted, many water bodies naturally do not meet one or more established water quality criteria at all times, even though they meet their designated use.[32] Data on exceedances of water quality criteria will provide critical information about the status of assessed waters, but it is the intent of this chapter to only list waters on the verified list that are impaired due to point source or nonpoint source pollutant discharges. It is not the intent of this chapter to include waters that do not meet water quality criteria solely due to natural conditions or physical alterations of the water body not related to pollutants. Similarly, it is not the intent of this chapter to include waters where designated uses are being met and where water quality criteria exceedances are limited to those parameters for which permitted mixing zones or other moderating provisions (such as site-specific alternative criteria) are in effect. Waters that do not meet applicable water quality standards due to natural conditions or to pollution not related to pollutants shall be noted in the state's water quality assessment prepared under subsection 305(b) of the CWA. This chapter is intended to interpret existing water quality criteria and evaluate attainment of established designated uses as set forth in Chapter 62-302, F.A.C., for the purposes of identifying water bodies or segments for which TMDLs will be established. It is not the intent of this chapter to establish new water quality criteria or standards, or to determine the applicability of existing criteria under other provisions of Florida law. In cases where this chapter relies on numeric indicators of ambient water quality as part of the methodology for determining whether existing narrative criteria are being met, these numeric values are intended to be used only in the context of developing a planning list and identifying an impaired water pursuant to this chapter. As such, exceedances of these numeric values shall not, by themselves, constitute violations of Department rules that would warrant enforcement action. Nothing in this rule is intended to limit any actions by federal, state, or local agencies, affected persons, or citizens pursuant to other rules or regulations. Pursuant to section 403.067, F.S., impaired waters shall not be listed on the verified list if reasonable assurance is provided that, as a result of existing or proposed technology-based effluent limitations and other pollution control programs under local, state, or federal authority, they will attain water quality standards in the future and reasonable progress towards attainment of water quality standards will be made by the time the next 303(d) list is scheduled to be submitted to EPA. Specific Authority 403.061, 403.067, FS. Law Implemented 403.021(11). 403.062, 403.067, FS. History -- New Subsection (1) of proposed Rule 62-303.100, Florida Administrative Code, refers to the narrowing and winnowing process (more fully described in subsequent portions of the proposed rule chapter) that will yield the Department's "updated list" of waters for which TMDLs will be calculated, which list will be submitted to the EPA in accordance with Section 303(d) of the Clean Water Act. (The Department last submitted such a list to the EPA in 1998. This list is referred to by the Department as its 1998 303(d) list.) The Department's intent not to include on its "updated list" of waters for which TMDLs will be calculated those "[w]aters that do not meet applicable water quality standards due to natural conditions or to pollution not related to pollutants," as provided in Subsection (2) of proposed Rule 62- 303.100, Florida Administrative Code, is consistent with the view expressed in Section 403.067, Florida Statutes, that TMDLs are appropriate only where there is man-induced pollution involving the discharge (from either a point or nonpoint source) of identifiable pollutants. See, e.g., Section 403.067(1), Florida Statutes ("[T]he development of a total maximum daily load program for state waters as required by s. 303(d) of the Clean Water Act, Pub. L. No. 92-500, 33 U.S.C. ss. 1251 et seq. will promote improvements in water quality throughout the state through the coordinated control of point and nonpoint sources of pollution"); Section 403.067(4), Florida Statutes ("If a surface water or water segment is to be listed under this subsection, the department must specify the particular pollutants causing the impairment and the concentration of those pollutants causing the impairment relative to the water quality standard."); and Section 403.067(6)(a)2., Florida Statutes ("For waters determined to be impaired due solely to factors other than point and nonpoint sources of pollution, no total maximum daily load will be required."). While "[w]aters that do not meet applicable water quality standards due to natural conditions or to pollution not related to pollutants" will not appear on the Department's "updated list" of waters for which TMDLs will be calculated, they will be included in the "water quality assessment prepared under subsection 305(b) of the CWA" (305(b) Report), which provides as follows: Each State shall prepare and submit to the Administrator by April 1, 1975, and shall bring up to date by April 1, 1976, and biennially thereafter, a report which shall include-- a description of the water quality of all navigable waters in such State during the preceding year, with appropriate supplemental descriptions as shall be required to take into account seasonal, tidal, and other variations, correlated with the quality of water required by the objective of this chapter (as identified by the Administrator pursuant to criteria published under section 1314(a) of this title) and the water quality described in subparagraph (B) of this paragraph; an analysis of the extent to which all navigable waters of such State provide for the protection and propagation of a balanced population of shellfish, fish, and wildlife, and allow recreational activities in and on the water; an analysis of the extent to which the elimination of the discharge of pollutants and a level of water quality which provides for the protection and propagation of a balanced population of shellfish, fish, and wildlife and allows recreational activities in and on the water, have been or will be achieved by the requirements of this chapter, together with recommendations as to additional action necessary to achieve such objectives and for what waters such additional action is necessary; an estimate of (i) the environmental impact, (ii) the economic and social costs necessary to achieve the objective of this chapter in such State, (iii) the economic and social benefits of such achievement, and (iv) an estimate of the date of such achievement; and a description of the nature and extent of nonpoint sources of pollutants, and recommendations as to the programs which must be undertaken to control each category of such sources, including an estimate of the costs of implementing such programs. The Administrator shall transmit such State reports, together with an analysis thereof, to Congress on or before October 1, 1975, and October 1, 1976, and biennially thereafter. The declaration made in Subsection (3) of proposed Rule 62-303.100, Florida Administrative Code, that "[t]his chapter is intended to interpret existing water quality criteria and evaluate attainment of established designated uses as set forth in Chapter 62-302, F.A.C., for the purposes of identifying water bodies or segments for which TMDLs will be established" is similar to that made in Subsection (9) of Section 403.067, Florida Statutes, that "[t]he provisions of this section are intended to supplement existing law, and nothing in this section shall be construed as altering any applicable state water quality standards." Subsection (5) of proposed Rule 62-303.100, Florida Administrative Code, together with proposed Rule 62-303.600, Florida Administrative Code (which will be discussed later), are designed to give effect to and make more specific the language in Subsection (4) of Section 403.067, Florida Statutes, that an impaired water may be listed on the Department's "updated list" of waters for which TMDLs will be calculated only "if technology-based effluent limitations and other pollution control programs under local, state, or federal authority, including Everglades restoration activities pursuant to s. 373.4592 and the National Estuary Program, which are designed to restore such waters for the pollutant of concern are not sufficient to result in attainment of applicable surface water quality standards." Section 403.061, Florida Statutes, which is cited as the "[s]pecific [a]uthority" for proposed Rule 62-303.100, Florida Statutes (and every other proposed rule in the proposed rule chapter), authorizes the Department to, among other things, "[a]dopt rules pursuant to ss. 120.536(1) and 120.54 to implement the provisions of [Chapter 403, Florida Statutes]." See Section 403.061(7), Florida Statutes. Section 403.062, Florida Statutes, which is included among the statutory provisions cited in proposed Rule 62- 303.100, Florida Statutes (and every other proposed rule in the proposed rule chapter) as the "[l]aw [i]mplemented," reads as follows: Code Pollution control; underground, surface, and coastal waters.-- The department and its agents shall have general control and supervision over underground water, lakes, rivers, streams, canals, ditches, and coastal waters under the jurisdiction of the state insofar as their pollution may affect the public health or impair the interest of the public or persons lawfully using them. Part I: Proposed Rule 62-303.150, Florida Administrative Proposed Rule 62-303.150, Florida Administrative Code, explains the "[r]elationship [b]etween [p]lanning and [v]erified [l]ists." It provides as follows: The Department shall follow the methodology in Section 62-303 300 to develop a planning list pursuant to subsection 403.067(2), F.S. As required by subsection 403.067(2), F.S., the planning list shall not be used in the administration or implementation of any regulatory program, and shall be submitted to EPA for informational purposes only. Waters on this planning list will be assessed pursuant to subsection 403.067(3) F.S., as part of the Department's watershed management approach. During this assessment, the Department shall determine whether the water body is impaired and whether the impairment is due to pollutant discharges using the methodology in Part III. The resultant verified list of impaired waters, which is the list of waters for which TMDLs will be developed by the Department pursuant to subsection 403.067(4), will be adopted by Secretarial Order and will be subject to challenge under subsection [sic] 120.569 and 120.57 F.S. Once adopted, the list will be submitted to the EPA pursuant to paragraph 303(d)(1) of the CWA. Consistent with state and federal requirements, opportunities for public participation, including workshops, meetings, and periods to submit comments on draft lists, will be provided as part of the development of planning and verified lists. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New The initial drafts of proposed Rule Chapter 62-303, Florida Administrative Code, provided for merely a single list of impaired waters needing TMDLs. It was only after the last TAC meeting (and before the first rule development workshop) that the concept of having two lists (a preliminary, "planning list" of potentially impaired waters requiring further assessment and a final, "verified list . . . of waters for which TMDLs will be developed by the Department") was incorporated into proposed Rule Chapter 62-303, Florida Administrative Code, by Department staff (although the idea of having a "potentially impaired subset" of impaired waters was discussed at TAC meetings). Such action was taken in response to concerns raised during the rule development process that the proposed rule chapter, as then drafted with its one-list methodology, "was too restrictive, that it would only get a small subset of waters on [the Departments 303(d)] list." To decrease, in a manner consistent with the provisions of Section 403.067, Florida Statutes, the chance that an impaired water needing a TMDL would be erroneously excluded, Department staff revised the proposed rule chapter to provide for a two-step listing process where potentially impaired waters would first be placed on a "planning list" based upon criteria generally less "restrictive" than the listing criteria contained in the previous drafts of the proposed rule chapter and then further tested (if necessary) and assessed to verify if, based upon criteria generally more rigorous than the "planning list" criteria, they should be included on a "verified list" of waters needing TMDLs (to be submitted to the EPA as the state's "updated" 303(d) list). Weighing against Department staff making it any easier for a water to be placed on the "verified list" was the significant regulatory consequence of such action. Erroneously listing a water as needing a TMDL would result in the unnecessary expenditure of considerable time, money, and effort. The more rigorous the listing criteria, the less likely it would be that a water would be listed erroneously and such unnecessary expenditures made. Subsequent to the ERC's adoption of proposed Rule Chapter 62-303, Florida Administrative Code, the National Research Council (NRC),33 through one of its committees,34 acting at the request of Congress to analyze the scientific basis of the nationwide TMDL program, issued a report entitled, "Assessing the TMDL Approach to Water Quality Management" (NRC Publication). In the NRC Publication, the committee endorses a "two-list process" like the one incorporated in proposed Rule Chapter 62-303, Florida Administrative Code, explaining as follows: Determining whether there should be some minimum threshold of data available when evaluating waterbodies for attainment of water quality standards is an issue of great concern to states. On the one hand, many call for using only the "best science" in making listing decisions, while others fear that many impaired waters will not be identified in the wait for additional data. The existence of a preliminary list addresses these concerns by focusing attention on waters suspected to be impaired without imposing on stakeholders and the agencies the consequences of TMDL development, until additional information is developed and evaluated. According to Subsection (1) of proposed Rule 62- 303.150, Florida Administrative Code, "[w]aters on th[e] planning list will be assessed pursuant to subsection 403.067(3) F.S., as part of the Department's watershed management approach." The following are the major concepts incorporated in the "Department's watershed management approach": The basin management unit is the geographic or spatial unit used to divide the state into smaller areas for assessment- -generally groups of Hydrologic Unit Codes (HUCs)[35] . . . . The basin management cycle is the five- year cycle within which watersheds are assessed and management plans developed and implemented. The Management Action Plan (MAP), a document developed over the five-year cycle and subsequently updated every five years, describes the watershed's problems and how participants plan to address them. Forums and communications networks allow participants to collect and evaluate as much information as possible on their individual basins and to reach a consensus on strategic monitoring, priority water bodies, and management strategies. The statewide basin management schedule establishes the proposed sequence for assessing individual watersheds. . . . Each individual basin cycle under the "Department's watershed management approach" takes five years to complete, and is "repeated every five years." It is, in other words, an iterative process. The five phases of the cycle are as follows: Phase I: Preliminary Basin Assessment; Phase II: Strategic Monitoring; Phase III: Data Analysis and TMDL Development; Phase IV: Management Action Plan; and Phase V: Implementation. The first two phases of the cycle are discussed in greater detail in proposed Rule 62-303.700, Florida Administrative Code. Part I: Proposed Rule 62-303.200, Florida Administrative Code Proposed Rule 62-303.200, Florida Administrative Code, contains definitions of various terms and phrases used in proposed Rule Chapter 62-303, Florida Administrative Code. It provides as follows: As used in this chapter: "BioRecon" shall mean a bioassessment conducted following the procedures outlined in "Protocols for Conducting a Biological Reconnaissance in Florida Streams," Florida Department of Environmental Protection, March 13. 1995, which is incorporated by reference.

"Total maximum daily load" (TMDL) for an impaired water body or water body segment shall mean the sum of the individual wasteload allocations for point sources and the load allocations for nonpoint sources and natural background. Prior to determining individual wasteload allocations and load allocations, the maximum amount of a pollutant that a water body or water segment can assimilate from all sources without exceeding water quality standards must first be calculated. A TMDL shall include either an implicit or explicit margin of safety and a consideration of seasonal variations. "Verified list" shall mean the list of impaired water bodies or segments for which TMDLs will be calculated, as provided in subsection 403.067(4), F.S., and which will be submitted to EPA pursuant to paragraph 303(d)(1) of the CWA.

"Waters" shall be those surface waters described in Section 403.031(13) Florida Statutes. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New There are some high salinity waters of the state that, although they do not have riverine input, nonetheless meet the definition of "estuary" found in Subsection (5) of proposed Rule 62-303.200, Florida Administrative Code, because they are "bays" or "lagoons," as those terms are used in the second sentence of Subsection (5). Rule Chapter 62-4, Florida Administrative Code, which is referenced in Subsections (6) and (23) of proposed Rule 62- 303.200, Florida Administrative Code, addresses the subject of "[p]ermits." According to Subsection (1) of Rule 62-4.210, Florida Administrative Code, "[n]o person shall construct any installation or facility which will reasonably be expected to be a source of . . . water pollution without first applying for and receiving a construction permit from the Department unless exempted by statute or Department rule." Subsection (1) of Rule 62-4.240, Florida Administrative Code, requires that "[a]ny person intending to discharge wastes into the waters of the State shall make application to the Department for an operation permit." An "operation permit" must: Specify the manner, nature, volume and frequency of the discharge permitted; Require proper operation and maintenance of any pollution abatement facility by qualified personnel in accordance with standards established by the Department; and Contain such additional conditions, requirements and restrictions as the Department deems necessary to preserve and protect the quality of the receiving waters and to ensure proper operation of the pollution control facilities. Rule 62-4.240(3), Florida Administrative Code. "An operation permit [will] be issued only if all Department requirements are met, including the provisions of Rules 62-302.300 and 62-302.700 and Rule 62-4.242, F.A.C." Rule 62-4.240(2), Florida Administrative Code. Subsection (1) of Rule 62-4.242, Florida Administrative Code, describes "[a]ntidegradation [p]ermitting [r]equirements." It provides as follows: Permits shall be issued when consistent with the antidegradation policy set forth in Rule 62-302.300 and, if applicable, Rule 62- 302.700. In determining whether a proposed discharge which results in water quality degradation is necessary or desirable under federal standards and under circumstances which are clearly in the public interest, the department shall consider and balance the following factors: Whether the proposed project is important to and is beneficial to the public health, safety, or welfare (taking into account the policies set forth in Rules 62- 302.100, 62-302.300, and, if applicable, 62- 302.700); and Whether the proposed discharge will adversely affect conservation of fish and wildlife, including endangered or threatened species, or their habitats; and Whether the proposed discharge will adversely affect the fishing or water-based recreational values or marine productivity in the vicinity of the proposed discharge; and Whether the proposed discharge is consistent with any applicable Surface Water Improvement and Management Plan that has been adopted by a Water Management District and approved by the Department. In addition to subsection (b) above, in order for a proposed discharge (other than stormwater discharges meeting the requirements of Chapter 62-25, F.A.C.), to be necessary or desirable under federal standards and under circumstances which are clearly in the public interest, the permit applicant must demonstrate that neither of the following is economically and technologically reasonable: Reuse of domestic reclaimed water. Use of other discharge locations, the use of land application, or reuse that would minimize or eliminate the need to lower water quality. Subsections (2) and (3) of Rule 62-4.242, Florida Administrative Code, prescribe "[s]tandards [a]pplying to Outstanding Florida Waters" and "[s]tandards [a]pplying to Outstanding National Resource Waters," respectively. Subsection (4) of Rule 62-4.242, Florida Administrative Code, "prescribe[s] the means by which the Department, upon the petition of a license applicant, will equitably allocate among such persons [directly discharging significant amounts of pollutants into waters which fail to meet one or more of the water quality criteria applicable to those waters] the relative levels of abatement responsibility of each for abatement of those pollutants." Subsection (1) of Rule 62-4.244, Florida Administrative Code, provides that the Department, upon application, may "allow the water quality adjacent to a point of discharge to be degraded to the extent that only the minimum conditions described in subsection 62-302.500(1), Florida Administrative Code, apply within a limited, defined region known as the mixing zone"; provided, that the "mixing zone" does not "significantly impair any of the designated uses of the receiving body of water." Subsection 502(6) of the Clean Water Act (33 U.S.C. Section 1362(6)), which is referenced in Subsection (12) of proposed Rule 62-303.200, Florida Administrative Code, provides as follows: The term "pollutant" means dredged spoil, solid waste, incinerator residue, sewage, garbage, sewage sludge, munitions, chemical wastes, biological materials, radioactive materials, heat, wrecked or discarded equipment, rock, sand, cellar dirt and industrial, municipal, and agricultural waste discharged into water. This term does not mean (A) "sewage from vessels or a discharge incidental to the normal operation of a vessel of the Armed Forces" within the meaning of section 1322 of this title; or (B) water, gas, or other material which is injected into a well to facilitate production of oil or gas, or water derived in association with oil or gas production and disposed of in a well, if the well used either to facilitate production or for disposal purposes is approved by authority of the State in which the well is located, and if such State determines that such injection or disposal will not result in the degradation of ground or surface water resources. Subsection 502(19) of the Clean Water Act (33 U.S.C. Section 1362(19)), which is referenced in Subsection (13) of proposed Rule 62-303.200, Florida Administrative Code, provides as follows: The term "pollution" means the man-made or man-induced alteration of the chemical, physical, biological, and radiological integrity of water. In Chapter 403, Florida Statutes, the definition of "pollution" is found, not in Subsection (2) of Section 403.031, Florida Statutes, as indicated in Subsection (13) of proposed Rule 62-303.200, Florida Administrative Code, but in Subsection (7) of the statute. The "water segments" referenced in the second sentence of Subsection (24) of proposed Rule 62-303.200, Florida Administrative Code, are, for the most part, either approximately five linear miles each (in the case of streams) or approximately five square miles each (in the case of waters not in a defined channel). Subsection (13) of Section 403.031, Florida Statutes, which is referenced in Subsection (25) of proposed Rule 62- 303.200, Florida Administrative Code, provides that "'[w]aters' include, but are not limited to, rivers, lakes, streams, springs, impoundments, wetlands, and all other waters or bodies of water, including fresh, brackish, saline, tidal, surface, or underground waters." The other terms and phrases defined in proposed Rule 62-303.200, Florida Administrative Code, will be discussed, where appropriate, later in this Final Order. Part II: Overview Part II of proposed Rule Chapter 62-303, Florida Administrative Code, contains the following provisions, which describe the "planning list" of potentially impaired waters and how the list will be compiled: Proposed Rules 62-303.300, 62- 303.320, 62-303.330, 62-303.340, 62-303.350, 62-303.351, 62- 303.352, 62-303.353, 62-303.360, 62-303.370, and 62-303.380, Florida Administrative Code. Code Part II: Proposed Rule 62-303.300, Florida Administrative Proposed Rule 62-303.300, Florida Administrative Code, is entitled, "Methodology to Develop the Planning List." It provides as follows: This part establishes a methodology for developing a planning list of waters to be assessed pursuant to subsections 403.067(2) and (3), F.S. A waterbody shall be placed on the planning list if it fails to meet the minimum criteria for surface waters established in Rule 62-302.500, F.A.C.; any of its designated uses, as described in this part; or applicable water quality criteria, as described in this part. It should be noted that water quality criteria are designed to protect either aquatic life use support, which is addressed in sections 62- 303.310-353, or to protect human health, which is addressed in sections 62-303.360- 380. Waters on the list of water segments submitted to EPA in 1998 that do not meet the data sufficiency requirements for the planning list shall nevertheless be included in the state's initial planning list developed pursuant to this rule. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New The second sentence of Subsection (1) of proposed Rule 62-303.300, Florida Administrative Code, incorporates the concept of "independent applicability" by providing that only one of the listed requirements need be met for a water to be placed on the "planning list." At the April 26, 2001, rule adoption hearing, the ERC initially voted to delete from proposed Rule Chapter 62-303, Florida Administrative Code, the language in Subsection (2) of proposed Rule 62-303.300, Florida Administrative Code. The ERC, however, later in the hearing, reversed itself after learning of a letter, dated April 26, 2001, that was sent to the Department by Beverly H. Bannister, the Director of the EPA's Region 4 Water Management Division. Ms. Bannister's letter read, in pertinent part, as follows: EPA expressed significant concern that, under earlier versions of the IWR [Impaired Waters Rule], waters currently identified as impaired on the State's 1998 Section 303(d) list which were determined to have "insufficient data" would be removed from the State's Section 303(d) list and also not appear on the State's planning list with its associated requirement for additional data collection. As a result of EPA concerns, the latest version of the IWR provides that waters on the current 1998 Section 303(d) list that do not meet the data sufficiency requirement of the planning list will be placed on the IWR's planning list, and sufficient data will be collected to verify the water's impairment status. In further discussions with the State regarding the EPA's concern about the 2002 Section 303(d) list, the State has committed to review all waters on the 1998 303(d) list and include all waters that meet the verification requirements of the IWR on the State's 2002 list. In addition, the State will also review all available data from 1989 to 1998 for development of a statewide planning list and include on the 2002 list any additional waters that meet the verification requirements, based on data from 1994 to 1998. (The State is unable to do a complete assessment for data gathered in 1999, 2000, and 2001 because of a national problem in the upload of data into the new Federal STORET data system.) Those waters on the 1998 303(d) list that do not meet the verification requirements will be de-listed for "good cause" and placed on the State's planning list as insufficient to verify the water's use-support status according to the methodology in the IWR. The "good cause" justification for de- listing the waters is based on several factors: 1) the requirements of the State Rule that these waters be moved to a planning list for additional data collection and assessment that will occur within a reasonable period of time; 2) a determination will be made that the waters are either impaired (and placed on the 303(d) list) or attaining its uses; and 3) the State's commitment to EPA that waters on the planning list that appeared on the State's 1998 Section 303(d) list will be monitored and assessed during the first or second rotation through the State's Watershed Management Process consistent with the schedule for TMDL development in EPA's consent decree with Earthjustice. High priority water/pollutant combinations will be monitored and assessed during the first rotation of the watershed cycle (i.e., within 5 years of 2001), and low priority water/pollutant combinations will be monitored and assessed during the second rotation of the watershed cycle (i.e., within 10 years of 2001). After this additional data collection and assessment, the water will be added to the appropriate future 303(d) list if the water is verified to be impaired, or the water will be "de- listed" based on the "good cause" justification that the water is attaining its uses. Waters on the 1998 303(d) list where sufficient data exists to demonstrate the water is meeting the IWR's planning list criteria for use support will be de-listed in the 2002 303(d) list submittal. It is EPA's view that this process will achieve the intent of the CWA and will provide sufficient documentation of the waters still requiring TMDLs by FDEP. Together with the data collection requirements found in Part III of the proposed rule chapter, Subsection (2) of proposed Rule 62-303.300, Florida Administrative Code, ensures that all waters on the Department's 1998 303(d) list (which list is referenced in Subsection (2)(c) of Section 403.067, Florida Statutes) will be assessed by the Department and that they will not be eliminated from consideration for TMDL development simply because there is not enough data to determine whether a TMDL is needed. Part II: Proposed Rule 62-303.310, Florida Administrative Code Proposed Rule 62-303.310, Florida Administrative Code, is entitled, "Evaluation of Aquatic Life Use Support." It provides as follows: A Class I, II, or III water shall be placed on the planning list for assessment of aquatic life use support (propagation and maintenance of a healthy, well-balanced population of fish and wildlife) if, based on sufficient quality and quantity of data, it: exceeds applicable aquatic life-based water quality criteria as outlined in section 62-303.320, does not meet biological assessment thresholds for its water body type as outlined in section 62-303.330, is acutely or chronically toxic as outlined in section 62-303.340, or exceeds nutrient thresholds as outlined in section 62-303.350. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New This proposed rule, like Subsection (1) of proposed Rule 62-303.300, Florida Administrative Code, incorporates the concept of "independent applicability." A water need meet only one of the four listed benchmarks to be placed on the "planning list for assessment of aquatic life use support." Each of these benchmarks is discussed at greater length in one or more of the subsequent sections of Part II of the proposed rule chapter. Part II: Proposed Rule 62-303.320, Florida Administrative Code Proposed Rule 62-303.320, Florida Administrative Code, addresses the "[e]xceedances of [a]quatic [l]ife-[b]ased [w]ater [q]uality [c]riteria" benchmark described in Subsection (1) of proposed Rule 62-303.310, Florida Administrative Code. It cites Sections 403.061 and 403.067, Florida Statutes, as its "[s]pecific [a]uthority" and Sections 403.062 and 403.067, Florida Statutes, as the "[l]aw[s] [i]mplemented" by the proposed rule. Proposed Rule 62-303.320, Florida Administrative Code, establishes a statistical method (involving "data modeling," as that term is used in Subsection (3)(b)4. of Section 403.067, Florida Statutes) for use in determining whether a water should be placed on the "planning list." It is not feasible, due to limited resources, to examine a water body at every point to determine its true overall condition. Rather, samples must be taken over time and inferences drawn from the sampling results, taking into consideration the "variability [of water quality] occurring in nature" and "that some deviations from water quality standards occur as the result of natural background conditions" (as the Legislature observed in Subsection (11) of Section 403.021, Florida Statutes). The process is, necessarily, characterized by a lack of certainty and the possibility of error. As stated in the NRC Publication: Given the finite monitoring resources, it is obvious that the number of sampling stations included in the state program will ultimately limit the number of water quality measurements that can be made at each station. Thus, in addition to the problem of defining state waters and designing the monitoring network to assess those waters, fundamental statistical issues arise concerning how to interpret limited data from individual sampling stations. Statistical inference procedures must be used on the sample data to test hypotheses about whether the actual condition in the water body meets the criterion. Thus, water quality assessment is a hypothesis-testing procedure. A statistical analysis of sample data for determining whether a water body is meeting a criterion requires the definition of a null hypothesis; for listing a water body, the null hypothesis would be that the water is not impaired. The analysis is prone to the possibility of both Type I error (a false conclusion that an unimpaired water is impaired) and Type II error (a false conclusion that an impaired water is not impaired). . . . The TAC and Department staff had extensive discussions regarding the issue of what particular type of "statistical analysis" to incorporate in the proposed rule chapter before deciding on a binomial distribution analysis. The binomial model is a time-tested nonparametric statistical method that is used where there are two possible outcomes, such as, in the case of water quality sampling, whether a water quality criterion has been exceeded or not. A parametric statistical analysis, based upon an assumption of normal distribution, which, unlike the binomial model incorporated in the proposed rule chapter, takes into account the magnitude of exceedances,36 was considered, but reasonably rejected by the TAC and Department staff because it was anticipated that, in many instances, the number of samples available to the Department would not be adequate to make the underlying distributional assumption with the requisite degree of certainty. The binomial model, which takes sample size into consideration, offers greater certainty with a limited number of samples than does the parametric statistical analysis that the TAC and Department staff rejected. Nonetheless, even in the case of the binomial model, the more samples there are, the more precise the analysis will be. Both Type I errors (false positives) and Type II errors (false negatives) decrease as sample size increases. To ensure greater analytic precision, proposed Rule 62-303.320, Florida Administrative Code, and its counterpart in Part III of the proposed rule chapter (proposed Rule 62-303.420, Florida Administrative Code) contain reasonable minimum sample size requirements (ten, with limited exceptions, for placement on the "planning list," and 20 for placement on the "verified list," which is ten more than the TAC recommended37). The NRC Publication contains the following discussion regarding the appropriateness of employing a binomial model to identify impaired waters needing TMDLs: The committee does not recommend any particular statistical method for analyzing monitoring data and for listing waters. However, one possibility is that the binomial hypothesis test could be required as a minimum and practical first step (Smith et al., 2001). The binomial method is not a significant departure from the current approach--called the raw score approach--in which the listing process treats all sample observations as binary values that either exceed the criterion or do not, and the binomial method has some important advantages. For example, one limitation of the raw score approach is that it does not account for the total number of measurements made. Clearly, 1 out of 6 measurements above the criterion is a weaker case for impairment than is 6 out of 36. The binomial hypothesis test allows one to take sample size into account. By using a statistical procedure, sample sizes can be selected and one can explicitly control and make trade-offs between error rates. (see Smith et al., 2001, and Gibbons, in press, for guidance in managing the risk of false positive and false negative errors). Several states, including Florida and Virginia, are considering or are already using the binomial hypothesis test to list impaired waters. Detailed examples of how to apply the test are beyond the scope of this document, but can be found in Smith et al. (2001) and the proposed Chapter 62-303 of the Florida Administrative Code. In a footnote, the committee added the following: The choice of Type I error rate is based on the assessor's willingness to falsely categorize a water body. It also is the case that, for any sample size, the Type II error rate decreases as the acceptable Type I error rate increases. The willingness to make either kind of mistake will depend on the consequences of the resulting action (more monitoring, costs to do a TMDL plan, costs to implement controls, possible health risk) and who bears the cost (public budget, private parties, etc.). The magnitude and burden of a Type I versus Type II error depend on the statement of the null hypothesis and on the sample size. When choosing a Type I error rate, the assessor may want to explicitly consider these determinants of error rates. The TAC recommended a Type I error rate of five percent (or, stated differently, a confidence level of 95 percent) be used in making listing decisions.38 Department staff responsible for drafting the proposed rule chapter, believing that, as a matter of policy, a 95 percent confidence level was too high and that a higher Type I error rate should be tolerated in order to reduce Type II error, reasonably settled on an 80 percent confidence level for placement on the "planning list" and a 90 percent confidence level for placement on the "verified list." Scientific studies generally do not employ a confidence level below 80 percent. A 50 percent confidence level is "comparable to flipping a coin." Use of the binomial model to determine impairment for purposes of TMDL development (based upon exceedances of water quality criteria) further requires the selection of a fixed "exceedance frequency" representing an acceptable rate of violation beneath which a water segment will not be considered impaired. A permissible "exceedance frequency" accounts for the natural variability of water quality and the uncertainty that the measurements taken are representative of the overall condition of the water segment sampled. The Department, pursuant to EPA guidance, has historically used a ten percent "exceedance frequency" for purposes of identifying, in its 305(b) Report, waters not meeting their designated uses. The TAC and Department staff agreed that a ten percent "exceedance frequency" should likewise be incorporated in the proposed rule chapter. The NRC Publication contains the following discussion regarding "exceedance frequencies" in general and a ten percent "exceedance frequency" in particular: Whether the binomial or the raw score approach is used, there must be a decision on an acceptable frequency of violation for the numeric criterion, which can range from 0 percent of the time to some positive number. Under the current EPA approach, 10 percent of the sample measurements of a given pollutant made at a station may exceed the applicable criterion without having to list the surrounding waterbody. The choice of 10 percent is meant to allow for uncertainty in the decision process. Unfortunately, simply setting an upper bound on the percentage of measurements at a station that may violate a standard provides insufficient information to properly deal with the uncertainty concerning impairment. The choice of acceptable frequency of violation is also supposed to be related to whether the designated use will be compromised, which is clearly dependent on the pollutant and on waterbody characteristics such as flow rate. A determination of 10 percent cannot be expected to apply to all water quality situations. In fact, it is inconsistent with federal water quality criteria for toxics that specify allowable violation frequencies of either one day in three years, four consecutive days in three years, or 30 consecutive days in three years (which are all less than 10 percent). Embedded in the EPA raw score approach is an implication that 10 percent is an acceptable violation rate, which it may not be in certain circumstances. Nonetheless, as the chairman of the committee that produced the NRC Publication, Dr. Kenneth Reckhow, testified at the final hearing in these consolidated cases when asked whether he "believe[d] that a determination of ten percent exceedance [frequency] cannot be expected to apply to all water quality situations": the "notion of one size fits all is . . . a pragmatic approach to the limits of what can be done in a regulatory environment." Dr. Reckhow, during his testimony, declined to "endorse[] as a scientist" the use of an "exceedance frequency" of ten percent (as opposed to some other "particular level"),39 but he stated his opinion (which the undersigned accepts) that "it is important to select a level, and from a science perspective it would be useful to see states employ a level like that or levels roughly around that point and see how effectively they have worked in terms of achieving the goal of meeting designated uses." Subsection (1) of proposed Rule 62-303.320, Florida Administrative Code, sets forth in tabular form, by sample size (from ten samples to 500 samples), the minimum number of exceedances needed for placement on the "planning list." It provides as follows: Water segments shall be placed on the planning list if, using objective and credible data, as defined by the requirements specified in this section, the number of exceedances of an applicable water quality criterion due to pollutant discharges is greater than or equal to the number listed in Table 1 for the given sample size. This table provides the number of exceedances that indicate a minimum of 10% exceedance frequency with a minimum of an 80% confidence level using a binomial distribution. Table 1: Planning List Minimum number of measured exceedances needed to put a water on the Planning list with at least 80% confidence that the actual exceedance rate is greater than or equal to ten percent.

Subsection (2) of proposed Rule 62-303.320, Florida Administrative Code, provides as follows: The U.S. Environmental Protection Agency's Storage and Retrieval (STORET) database shall be the primary source of data used for determining water quality criteria exceedances. As required by rule 62- 40.540(3), F.A.C., the Department, other state agencies, the Water Management Districts, and local governments collecting surface water quality data in Florida shall enter the data into STORET within one year of collection. Other sampling entities that want to ensure their data will be considered for evaluation should ensure their data are entered into STORET. The Department shall consider data submitted to the Department from other sources and databases if the data meet the sufficiency and data quality requirements of this section. STORET is a "centralized data repository" maintained by the EPA. It contains publicly available water quality data, contributed by state agencies and others, on waters throughout the nation. Subsection (3) of Rule 62-40.540, Florida Administrative Code, which is referenced in Subsection (2) of proposed Rule 62-303.320, Florida Administrative Code, provides that "[t]he U.S. Environmental Protection Agency water quality data base (STORET) shall be the central repository of the state's water quality data" and that"[a]ll appropriate water quality data collected by the Department, Districts, local governments, and state agencies shall be placed in the STORET system within one year of collection." At the end of 1998, STORET underwent a major overhaul. It is "now more accommodating of meta data," which is auxiliary information about the underlying data. As Ms. Bannister indicated in her April 26, 2001, letter to the Department, there was a "problem in the upload of data into the new Federal STORET data system." This new version of STORET is still not "very user-friendly." Subsection (2) of proposed Rule 62-303.320, Florida Administrative Code, however, while it strongly encourages the entry of data into STORET, does not require that data be entered into STORET to be considered by the Department in determining whether there have been the requisite number of exceedances for placement on the "planning list," as the last sentence of Subsection (2) makes abundantly clear. Subsection (3) of proposed Rule 62-303.320, Florida Administrative Code, imposes reasonable age-related restrictions on what data can be used to determine whether a water should be placed on the "planning list" based upon "[e]xceedances of [a]quatic [l]ife-[b]ased [w]ater [q]uality [c]riteria." It provides as follows: When determining water quality criteria exceedances, data older than ten years shall not be used to develop planning lists. Further, more recent data shall take precedence over older data if: the newer data indicate a change in water quality and this change is related to changes in pollutant loading to the watershed or improved pollution control mechanisms in the watershed contributing to the assessed area, or the Department determines that the older data do not meet the data quality requirements of this section or are no longer representative of the water quality of the segment. The Department shall note for the record that the older data were excluded and provide details about why the older data were excluded. These provisions are reasonably designed to increase the likelihood that the decision to place a water on the "planning list" will be based upon data representative of the water's current conditions. While the data that will be excluded from consideration by Subsection (3) of proposed Rule 62-303.320, Florida Administrative Code, may be objective and credible data, such data merely reflects what the conditions of the water in question were at the time the samples yielding the data were collected. Declining to rely on this data because it is too old to be a reliable indicator of current conditions is not unreasonable. The TAC recommended that listing decisions be based on data no older than five years.40 Department staff, however, believed that, for purposes of compiling a "planning list," a ten-year cut-off was more appropriate. The binomial model is predicated on independent sampling. Subsection (4) of proposed Rule 62-303.320, Florida Administrative Code, addresses "in a very straightforward, simple, but reasonable way, the notion of spatial independence and temporal independence." It provides as follows: To be assessed for water quality criteria exceedances using Table 1, a water segment shall have a minimum of ten, temporally independent samples for the ten year period. To be treated as an independent sample, samples from a given station shall be at least one week apart. Samples collected at the same location less than seven days apart shall be considered as one sample, with the median value used to represent the sampling period. However, if any of the individual values exceed acutely toxic levels, then the worst case value shall be used to represent the sampling period. The worst case value is the minimum value for dissolved oxygen, both the minimum and maximum for pH, or the maximum value for other parameters. However, when data are available from diel or depth profile studies, the lower tenth percentile value shall be used to represent worst case conditions. For the purposes of this chapter, samples collected within 200 meters of each other will be considered the same station or location, unless there is a tributary, an outfall, or significant change in the hydrography of the water. Data from different stations within a water segment shall be treated as separate samples even if collected at the same time. However, there shall be at least five independent sampling events during the ten year assessment period, with at least one sampling event conducted in three of the four seasons of the calendar year. For the purposes of this chapter, the four seasons shall be January 1 through March 31, April 1 through June 30, July 1 through September 30, and October 1 through December 31. States may set their "[a]quatic [l]ife-[b]ased [w]ater [q]uality [c]riteria" at either acutely toxic levels or chronically toxic levels. The EPA, based on data from toxicity tests, has determined what these acutely toxic levels and chronically toxic levels should be, and it has provided its recommendations to the states for their use in setting appropriate water quality criteria. With one exception (involving silver in predominantly marine waters), the Department, in Rule Chapter 62-302, Florida Administrative Code, has opted to establish "[a]quatic [l]ife-[b]ased [w]ater [q]uality [c]riteria" at chronically toxic levels, rather than at acutely toxic levels, because chronic-toxicity-based criteria are, in the Department's view, "more protective." Subsection (4) of proposed Rule 62-303.320, Florida Administrative Code, will require the Department, under certain circumstances, to determine whether acutely toxic levels of parameters listed in Rule Chapter 62-302, Florida Administrative Code (other than silver in predominantly marine waters) have been exceeded. Neither the Department's existing rules, nor the proposed rule chapter, specifies what these levels are. In making this determination, the Department intends to use the acutely toxic levels recommended by the EPA. The last two sentences of Subsection (4) of proposed Rule 62-303.320, Florida Administrative Code, address "seasonal . . . variations," as required by Subsection (3)(b)1. of Section 403.067, Florida Statutes, and do so in a manner consistent with the TAC's recommendation on the matter. As Subsection (3)(b)1. of Section 403.067, Florida Statutes, suggests, water quality may vary from season to season. Such variations tend to be more pronounced in the northern part of the state than in South Florida in the case of certain parameters, such as dissolved oxygen, which is usually "at its critical condition" during the warmer months. While certain types of exceedances may be more likely to occur during a particular season or seasons of the year, exceedances may occur at any time during the year. Department staff, as recommended by the TAC, included the last two sentences in Subsection (4) of proposed Rule 62-303.320, Florida Administrative Code, in a reasonable effort to avoid a situation where a listing decision would be based upon skewed data (provided by persons "with an agenda") reflecting only isolated instances of worst or best case conditions, as opposed to "data . . . spread throughout the year as much as possible." Data from each of the four seasons of the calendar year were not required "because then some data sets might be excluded just because they missed a quarterly sample," an outcome the TAC and Department staff considered to be undesirable because they "wanted to be all-inclusive and . . . capture all waters that in fact might even potentially be impaired" on the "planning list." Notwithstanding the "three out of four seasons" data sufficiency requirement of Subsection (4) of proposed Rule 62-303.320, Florida Administrative Code, because the proposed rule establishes an "exceedance frequency" threshold of ten percent, a water may qualify for placement on the "planning list" under the proposed rule even though all of the exceedances evidenced by the data in the Department's possession (covering at least three of the four seasons of the year) occurred in the one season when conditions are typically at their worst for the water. (If there were other exceedances, they would not be excluded from consideration under the proposed rule simply because they occurred during a time of year when exceedances are atypical.) The "three out of four seasons" requirement does not completely protect against persons "with an agenda" obtaining the result they want by providing the Department skewed data, but, as Dr. Reckhow testified at the final hearing, it would be difficult, if not impossible, for the Department to devise a rule which provides for Department consideration of data submitted by members of the public and, at the same time, completely "prevent[s] someone who is clever [enough] from contriving the analysis." As Dr. Reckhow pointed out, to counteract the data submissions of such a person, those who believe that the data is not truly representative of the overall condition of the water can "collect their own data and make the[ir] case" to the Department. Subsection (5) of proposed Rule 62-303.320, Florida Administrative Code, which reads as follows, provides two exceptions to the data sufficiency requirements of Subsection of the proposed rule: Notwithstanding the requirements of paragraph (4), water segments shall be included on the planning list if: there are less than ten samples for the segment, but there are three or more temporally independent exceedances of an applicable water quality criterion, or there are more than one exceedance of an acute toxicity-based water quality criterion in any three year period. The "three or more exceedances" exception (found in Subsection (5)(a) of proposed Rule 62-303.320, Florida Administrative Code) to the proposed rule's minimum sample size requirement of ten was not something that the "TAC ever voted on." It was included in the proposed rule by Department staff at the request of Petitioners. As noted above, the only "acute toxicity-based water quality criterion" in Rule Chapter 62-302, Florida Administrative Code, is the criterion for silver in predominantly marine waters. Accordingly, Subsection (5)(b) of proposed Rule 62-330.320, Florida Administrative Code, applies only where that criterion has been exceeded (more than once in a three year period). Subsection (6) of proposed Rule 62-330.320, Florida Administrative Code, provides that certain data (described therein) will be excluded from consideration by the Department in determining whether a water should be placed on the "planning list" pursuant to the proposed rule. It reads as follows: Values that exceed possible physical or chemical measurement constraints (pH greater than 14, for example) or that represent data transcription errors shall be excluded from the assessment. Outliers identified through statistical procedures shall be evaluated to determine whether they represent valid measures of water quality. If the Department determines that they are not valid, they shall be excluded from the assessment. However, the Department shall note for the record that the data were excluded and explain why they were excluded. The exclusion of the data described in Subsection (6) of proposed Rule 62-330.320, Florida Administrative Code, is entirely appropriate. Indeed, it would be unreasonable for the Department to consider such data. Earlier versions of Subsection (6) of proposed Rule 62-330.320, Florida Administrative Code, automatically excluded outliers from consideration. The ERC-adopted version, however, provides that outliers will first be identified41 and then examined and, only if they are determined by the Department, using its "best professional judgment," not to be "valid measures of water quality," will they be excluded from consideration. (Values, although extreme, may nonetheless "represent valid measures of water quality."). Subsection (7) of proposed Rule 62-303.320, Florida Administrative Code, which provides as follows, addresses "[q]uality assurance and [q]uality control protocols," as those terms are used in Subsection (3)(b)3. of Section 403.067, Florida Statutes: The Department shall consider all readily available water quality data. However, to be used to determine water quality exceedances, data shall be collected and analyzed in accordance with Chapter 62-160, F.A.C., and for data collected after one year from the effective date of this rule, the sampling agency must provide to the Department, either directly or through entry into STORET, all of the data quality assessment elements listed in Table 2 of the Department's Guidance Document "Data Quality Assessment Elements for Identification of Impaired Surface Waters" (DEP EAS 01-01, April 2001), which is incorporated by reference. Rule Chapter 62-160, Florida Administrative Code, which is referenced in Subsection (7)(a) of proposed Rule 62- 303.320, Florida Administrative Code, contains "[q]uality assurance requirements" that, with certain limited exceptions, "apply to all programs, projects, studies, or other activities which are required by the Department, and which involve the measurement, use, or submission of environmental data or reports to the Department." Rule 62-160.110, Florida Administrative Code. Adherence to quality assurance requirements such as those in Rule Chapter 62-160, Florida Administrative Code, is essential to obtaining data that is objective and credible. Compliance with these requirements makes it less likely that sampling results will be inaccurate. DEP EAS 01-01, April 2001, which is incorporated by reference in Subsection (7)(b) of proposed Rule 62-303.320, Florida Administrative Code, provides as follows: The Department relies on environmental data from a variety of sources to carry out its mission. Those data must satisfy the needs for which they are collected, comply with applicable standards, specifications and statutory requirements, and reflect a consideration of cost and economics. Careful project planning and routine project and data reviews, are essential to ensure that the data collected are relevant to the decisions being made. Many aspects of a project affect data quality. Sampling design, selection of parameters, sampling technique, analytical methodologies and data management activities are a few such aspects, whether the data are being collected for a compliance program, or for research activities. The level of quality of each of those elements will affect the final management decisions that are based on a project's outcome. Data quality assessment is one activity that is instrumental in ensuring that data collected are relevant and appropriate for the decisions being made. Depending on the needs of the project, the intended use of the final data and the degree of confidence required in the quality of the results, data quality assessment can be conducted at many levels. For the purposes of identification of impaired surface waters, the level of data quality assessment to be conducted (Table 1) requires providing the appropriate data elements (Table 2). If the data and applicable data elements are in an electronic format, data quality assessments can be performed automatically on large volumes of data using software tools, without significant impact to staffing. Department programs can realize significant improvement in environmental protection without additional process using these types of review routinely.

Subsection (8) of proposed Rule 62-303.320, Florida Administrative Code, also addresses "[q]uality assurance and [q]uality control protocols." It reads as follows: To be used to determine exceedances of metals criteria, surface water data for mercury shall be collected and analyzed using clean sampling and analytical techniques, and the corresponding hardness value shall be required to determine exceedances of freshwater metals criteria that are hardness dependent, and if the ambient hardness value is less than 25 mg/L as CaCO3, then a hardness value of 25 will be used to calculate the criteria. If data are not used due to sampling or analytical techniques or because hardness data were not available, the Department shall note for the record that data were excluded and explain why they were excluded. The "clean sampling and analytical techniques" referenced in Subsection (8)(a) of proposed Rule 62-303.320, Florida Administrative Code, are, as noted above, defined in Subsection (2) of proposed Rule 62-303.200, Florida Administrative Code, as "those applicable field sampling procedures and analytical methods" permitted by the EPA's "Method 1669." "Method 1669" is a "performance-based," "guidance document" that, as its "Introduction" and introductory "Note," which read, in pertinent part, as follows, reveal, allows for the use of procedures other than those specifically described therein for "[s]ampling [a]mbient [w]ater for [t]race [m]etals at EPA [w]ater [q]uality [c]riteria [l]evels": . . . . In developing these methods, EPA found that one of the greatest difficulties in measuring pollutants at these levels was precluding sample contamination during collection, transport, and analysis. The degree of difficulty, however, is dependent on the metal and site-specific conditions. This method, therefore, is designed to provide the level of protection necessary to preclude contamination in nearly all situations. It is also designed to provide the protection necessary to produce reliable results at the lowest possible water quality criteria published by EPA. In recognition of the variety of situations to which this method may be applied, and in recognition of continuing technological advances, the method is performance-based. Alternative procedures may be used, so long as those procedures are demonstrated to yield reliable results. . . . Note: This document is intended as guidance only. Use of the terms "must," "may," and "should" are included to mean that the EPA believes that these procedures must, may, or should be followed in order to produce the desired results when using this guidance. In addition, the guidance is intended to be performance-based, in that the use of less stringent procedures may be used as long as neither samples nor blanks are contaminated when following those modified procedures. Because the only way to measure the performance of the modified procedures is through the collection and analysis of uncontaminated blank samples in accordance with this guidance and the referenced methods, it is highly recommended that any modification be thoroughly evaluated and demonstrated to be effective before field samples are collected. Subsection (8)(a) of proposed Rule 62-303.320, Florida Administrative Code, requires that "Method 1669"- permitted procedures be used only where a water is being tested to determine if it exceeds the criterion for mercury (.012 micrograms per liter in the case of Class I waters and Class III freshwaters, and .025 micrograms per liter in the case of Class II waters and Class III marine waters). Use of these procedures is necessary to avoid the sample contamination (from, among other things, standard lab bottles, hair, dandruff, atmospheric fallout, and pieces of cotton from clothing) which commonly occurs when standard, non- "Method 1669"-permitted techniques are used. Because "the criteria [for mercury are] so low" and may be exceeded due solely to such contamination, it is essential to employ "Method 1669"-permitted techniques in order to obtain results that are reliable and meaningful. The "Method 1669"-permitted techniques are approximately five times more costly to employ than standard techniques and the Department's laboratory is the only laboratory in the state (with the possible exception of a laboratory at Florida International University) able to provide "clean sampling and analytical techniques" to measure mercury levels in surface water. Nonetheless, as Timothy Fitzpatrick, the Department's chief chemist, testified at the final hearing in these consolidated cases: [I]f you want to measure methyl mercury or total mercury in surface water, you have to use clean techniques or you're measuring noise. And the whole purpose behind using clean techniques is to do sound science and to have confidence in the number. It's not to determine whether or not you're throwing out a body of data. It's to be able to get numbers that make sense. And there's no point in having a database full of information that's virtually worthless because it contains noise, analytical noise. As Subsection (8)(b) of proposed Rule 62-303.320, Florida Administrative Code, suggests, there are certain "metals for which the actual water quality criterion itself changes as the hardness [of the water, measured in milligrams per liter calcium carbonate] changes." Criteria for these metals are set (in the table contained in Rule 62-302.530, Florida Administrative Code) at higher levels for high hardness waters than for low hardness waters. To know which criterion applies in a particular case, the Department needs to know the hardness of the water sampled. Subsection (9) of proposed Rule 62-303.320, Florida Administrative Code, guards against reliance on data that, due to the use of inappropriate methods, may fail to reveal exceedances that actually exist. It provides as follows: Surface water data with values below the applicable practical quantification limit (PQL) or method detection limit (MDL) shall be assessed in accordance with Rules 62- 4.246(6)(b)-(d) and (8), F.A.C. If sampling entities want to ensure that their data will be considered for evaluation, they should review the Department's list of approved MDLs and PQLs developed pursuant to Rule 62-4.246, F.A.C., and, if available, use approved analytical methods with MDLs below the applicable water quality criteria. If there are no approved methods with MDLs below a criterion, then the method with the lowest MDL should be used. Analytical results listed as below detection or below the MDL shall not be used for developing planning lists if the MDL was above the criteria and there were, at the time of sample collection, approved analytical methods with MDLs below the criteria on the Department's list of approved MDLs and PQLs. If appropriate analytical methods were used, then data with values below the applicable MDL will be deemed to meet the applicable water quality criterion and data with values between the MDL and PQL will be deemed to be equal to the MDL. Subsections (6)(b) through (d) and (8) of Rule 62- 4.246, Florida Administrative Code, provide as follows: All results submitted to the Department for permit applications and monitoring shall be reported as follows: The approved analytical method and corresponding Department-established MDL and PQL levels shall be reported for each pollutant. The MDLs and PQLs incorporated in the permit shall constitute the minimum reporting levels for each parameter for the life of the permit. The Department shall not accept results for which the laboratory's MDLs or PQLs are greater than those incorporated in the permit. All results with laboratory MDLs and PQLs lower than those established in the permit shall be reported to the Department. Unless otherwise specified, all subsequent references to MDL and PQL pertain to the MDLs and PQLs incorporated in the permit. Results greater than or equal to the PQL shall be reported as the measured quantity. Results less than the PQL and greater than or equal to the MDL shall be reported as less than the PQL and deemed to be equal to the MDL. Results less than the MDL shall be reported as less than the MDL. * * * (8) The presence of toxicity (as established through biomonitoring), data from analysis of plant or animal tissue, contamination of sediment in the vicinity of the installation, intermittent violations of effluent limits or water quality standards, or other similar kinds of evidence reasonably related to the installation may indicate that a pollutant in the effluent may cause or contribute to violations of water quality criteria. If there is such evidence of possible water quality violations, then (unless the permittee has complied with subsection (9) below) in reviewing reports and applications to establish permit conditions and determine compliance with permits and water quality criteria, the Department shall treat any result less than the MDL of the method required in the permit or the method as required under subsection (10) below or any lower MDL reported by the permittee's laboratory as being one half the MDL (if the criterion equals or exceeds the MDL) or one half of the criterion (if the criterion is less than the MDL), for any pollutant. Without the permission of the applicant, the Department shall not use any values determined under this subsection or subsection (9) below for results obtained under a MDL superseded later by a lower MDL. The final subsection of proposed Rule 62-303.320, Florida Administrative Code, Subsection (10), provides as follows: It should be noted that the data requirements of this rule constitute the minimum data set needed to assess a water segment for impairment. Agencies or groups designing monitoring networks are encouraged to consult with the Department to determine the sample design appropriate for their specific monitoring goals. Proposed Rule 62-303.320, Florida Administrative Code, establishes a relatively "rigid" framework, based upon statistical analysis of data, with little room for the exercise of "best professional judgment," for determining whether a water qualifies for placement on the "planning list." There are advantages to taking such a "cookbook" approach. It promotes administrative efficiency and statewide uniformity in listing decisions. Furthermore, as Dr. Reckhow pointed out during his testimony, it lets the public know "how a [listing] decision is arrived at" and therefore "makes it easier for the public to get engaged and criticize the outcome." Such "rigidity," however, comes at a price, as Dr. Reckhow acknowledged, inasmuch as observations and conclusions (based upon those observations) made by the "experienced biologist who really understands the system . . . get[] lost." While proposed Rule 62-303.320, Florida Administrative Code, may rightfully be characterized as a "rigid statistical approach," it must be remembered that, in the subsequent portions of Part II of the proposed rule chapter, the Department provides other ways for a water to qualify for placement on the "planning list." A discussion of these alternatives follows. Code Part II: Proposed Rule 62-303.330, Florida Administrative Proposed Rule 62-303.330, Florida Administrative Code, is entitled, "Biological Assessment." As noted in Subsection (2) of proposed Rule 62-303.310, Florida Administrative Code, it "outline[s]" the requirements that must be met for a water to qualify for placement on the "planning list" based upon a failure to "meet biological assessment thresholds for its water body type." It lists Sections 403.061 and 403.067, Florida Statutes, as its "[s]pecific [a]uthority" and Sections 403.062 and 403.067, Florida Statutes, as the "[l]aw [i]mplemented." A "[b]iological [a]ssessment" provides more information about the overall ability of a water to sustain aquatic life than does the "data used for determining water quality exceedances" referenced in Subsection (2) of proposed Rule 62-303.320, Florida Administrative Code. This is because "[b]iological [a]ssessment[s]," as is noted in the NRC Publication, "integrate the effects of multiple stressors over time and space." As Mr. Joyner pointed out in his testimony, a "[b]iological [a]ssessment" is "more than just a snapshot like a water quality sample is of the current water quality [at the particular location sampled]." Unlike proposed Rule 62-303.320, Florida Administrative Code, proposed Rule 62-303.330, Florida Administrative Code, deals with "biological criteria," not "numerical criteri[a]," as those terms are used in Subsection (3)(c) of Section 403.067, Florida Statutes, and the method it establishes for determining "planning list" eligibility does not involve statistical analysis. Subsection (1) of proposed Rule 62-303.330, Florida Administrative Code, provides that "[b]iological data must meet the requirements of paragraphs (3) and (7) in section 62- 303.320," Florida Administrative Code, which, as noted above, impose age ("paragraph" (3)) and quality assurance/quality control and data submission ("paragraph" (7)) restrictions on the use of data. While the "biological component of STORET is not . . . usable" at this time and the biological database maintained by the Department "is not a database where members of the public can input data," pursuant to "paragraph" (7)(b) of proposed Rule 62-303.320, Florida Administrative Code, data collected by someone outside the Department that is not entered into either STORET or the Department's own biological database may still be considered by the Department if it is provided "directly" to the Department. Inasmuch as "[b]iological [a]ssessment[s]" reflect the "effects of multiple stressors over time and space," failed assessments are no more likely during one particular time of the year than another. Consequently, there is no need to limit the time of year in which "[b]iological [a]ssessment[s]" may be conducted. The first sentence of Subsection (2) of proposed Rule 62-303.330, Florida Administrative Code, provides that "[b]ioassessments used to assess streams and lakes under this rule shall include BioRecons, Stream Condition Indices (SCIs), and the benthic macroinvertebrate component of the Lake Condition Index (LCI), which only applies to clear lakes with a color less than 40 platinum cobalt units." The BioRecon and SCI, as those terms are defined in Subsections (1) and (18), respectively, of proposed Rule 62- 303.200, Florida Administrative Code, are rapid bioassessment protocols for streams developed by the Department. They are "similar to the original rapid bioassessment protocols that were designed by the U.S. EPA in [19]89." Conducting a BioRecon or SCI requires the deployment of a Standard D frame dip net approximately one and a half meters in length (including its handle), which is used to obtain samples of the best available habitat that can be reached. The samples are obtained by taking "sweeps" with the one and a half meter long dip net. Both wadable and non-wadable streams can be, and have been, sampled using this method prescribed by the BioRecon and SCI, although sampling is "more challenging when the water body is deeper than waist deep." In these cases, a boat is used to navigate to the areas where sampling will occur. The sampling "methods are identical regardless of the depth of the water." The BioRecon and SCI both include an assessment of the health of the habitat sampled, including the extent of habitat smothering from sediments and bank instability. The purpose of such an assessment is "to ascertain alteration of the physical habitat structure critical to maintenance of a healthy biological condition." Like all bioassessment protocols, the BioRecon and SCI employ "reasonable thresholds" of community health (arrived at by sampling "reference sites," which are the least affected and impacted sites in the state) against which the health of the sampled habitat is measured. Impairment is determined by the sampled habitat's departure from these "reasonable thresholds" (which represent expected or "reference" conditions). The BioRecon is newer, quicker and less comprehensive than the SCI. Only four sweeps of habitat are taken for the BioRecon, compared to 20 sweeps for the SCI. Furthermore, the BioRecon takes into consideration only three measures of community health (taxa richness, Ephemeroptera/ Plecoptera/Tricoptera Index, and Florida Index), whereas the SCI takes into account four additional measures of community health. For these reasons, the BioRecon is considered a "screening version" of the SCI. Like the BioRecon and the SCI, the LCI is a "comparative index." Conditions at the sampled site are compared to those at "reference sites" to determine the health of the aquatic community at the sampled site. Samples for the LCI are taken from the sublittoral zone of the targeted lake,42 which is divided into twelve segments. Using a petite PONAR or Ekman sampler dredge, a sample is collected from each of the twelve segments. The twelve samples are composited into a single, larger sample, which is then examined to determine what organisms it contains. The results of such examination are considered in light of six measures of community health: Total taxa, EOT taxa, percent EOT, percent Diptera, the Shannon-Weiner Diversity Index, and the Hulbert Index. Lakes larger than 1,000 acres are divided into two subbasins or into quadrants (as appropriate), and each subbasin or quadrant is sampled separately, as if it were a separate site. It is essential that persons conducting BioRecons, SCIs, and LCIs know the correct sampling techniques to use and have the requisite amount of taxonomic knowledge to identify the organisms that may be found in the samples collected. For this reason, a second sentence was included in Subsection (2) of proposed Rule 62-303.330, Florida Administrative Code, which reads as follows: Because these bioassessment procedures require specific training and expertise, persons conducting the bioassessments must comply with the quality assurance requirements of Chapter 62-160, F.A.C., attend at least eight hours of Department sanctioned field training, and pass a Department sanctioned field audit that verifies the sampler follows the applicable SOPs in Chapter 62-160, F.A.C., before their bioassessment data will be considered valid for use under this rule. The Department has developed SOPs for BioRecons, SCIs, and LCIs, which are followed by Department personnel who conduct these bioassessments. The Department is in the process of engaging in rulemaking to incorporate these SOPs in Rule Chapter 62-160, Florida Administrative Code, but had not yet, as of the time of the final hearing in these consolidated cases, completed this task.43 Subsection (3) of proposed Rule 62-303.330, Florida Administrative Code, provides as follows: Water segments with at least one failed bioassessment or one failure of the biological integrity standard, Rule 62- 302.530(11), shall be included on the planning list for assessment of aquatic life use support. In streams, the bioassessment can be an SCI or a BioRecon. Failure of a bioassessment for streams consists of a "poor" or "very poor" rating on the Stream Condition Index, or not meeting the minimum thresholds established for all three metrics (taxa richness, Ephemeroptera/Plecoptera/Tricoptera Index, and Florida Index) on the BioRecon. Failure for lakes consists of a "poor" or "very poor" rating on the Lake Condition Index. Subsection (11) of Rule 62-302.530, Florida Administrative Code, prescribes the following "biological integrity standard[s]" for Class I, II and III waters: Class I The Index for benthic macroinvertebrates shall not be reduced to less than 75% of background levels as measured using organisms retained by a U.S. Standard No. 30 sieve and collected and composited from a minimum of three Hester-Dendy type artificial substrate samplers of 0.10 to 0.15m2 area each, incubated for a period of four weeks. Class II The Index for benthic macroinvertebrates shall not be reduced to less than 75% of established background levels as measured using organisms retained by a U.S. Standard No. 30 sieve and collected and composited from a minimum of three natural substrate samples, taken with Ponar type samplers with minimum sampling area of 2252. Class III: Fresh The Index for benthic macroinvertebrates shall not be reduced to less than 75% of established background levels as measured using organisms retained by a U.S. Standard No. 30 sieve and collected and composited from a minimum of three Hester-Dendy type artificial substrate samplers of 0.10 to 0.15m2 area each, incubated for a period of four weeks. Class III: Marine The Index for benthic macroinvertebrates shall not be reduced to less than 75% of established background levels as measured using organisms retained by a U.S. Standard No. 30 sieve and collected and composited from a minimum of three natural substrate samples, taken with Ponar type samplers with minimum sampling area of 2252. The "Index" referred to in these standards is the Shannon-Weaver Diversity Index. Subsection (4) of proposed Rule 62-303.330, Florida Administrative Code, which reads as follows, allows the Department to rely upon "information relevant to the biological integrity of the water," other than a failure of a BioRecon, SCI, or LCI or a failure of the "biological integrity standard" set forth in Subsection (11) of Rule 62-302.530, Florida Administrative Code, to place a water on the "planning list" where the Department determines, exercising its "best professional judgment," that such "information" reveals that "aquatic life use support has [not] been maintained": Other information relevant to the biological integrity of the water segment, including information about alterations in the type, nature, or function of a water, shall also be considered when determining whether aquatic life use support has been maintained. The "other information" that would warrant placement on the "planning list" is not specified in Subsection (4) because, as Mr. Frydenborg testified at the final hearing, "[t]he possibilities are so vast." Proposed Rule 62-303.330, Florida Administrative Code, does not make mention of any rapid type of bioassessment for estuaries, the failure of which will lead to placement of a water on the "planning list," for the simple reason that the Department has yet to develop such a bioassessment.44 Estuaries, however, may qualify for "planning list" placement under proposed Rule 62-303.330, Florida Administrative Code, based upon "one failure of the biological integrity standard," pursuant to Subsection (3) of the proposed rule,45 or based upon "other information," pursuant to Subsection (4) of the proposed rule (which may include "information" regarding seagrasses, aquatic macrophytes, or algae communities). Part II: Proposed Rule 62-303.340, Florida Administrative Code Proposed Rule 62-303.340, Florida Administrative Code, is entitled, "Toxicity," and, as noted in Subsection (3) of proposed Rule 62-303.310, Florida Administrative Code, "outline[s]" the requirements that must be met for a water to qualify for placement on the "planning list" based upon it being "acutely or chronically toxic." These requirements, like those found in proposed Rule 62-303.330, Florida Administrative Code, relating to "[b]iological [a]ssessment[s]," are not statistically-based. They are as follows: All toxicity tests used to place a water segment on a planning list shall be based on surface water samples in the receiving water body and shall be conducted and evaluated in accordance with Chapter 62- 160, F.A.C., and subsections 62-302.200(1) and (4), F.A.C., respectively. Water segments with two samples indicating acute toxicity within a twelve month period shall be placed on the planning list. Samples must be collected at least two weeks apart over a twelve month period, some time during the ten years preceding the assessment. Water segments with two samples indicating chronic toxicity within a twelve month period shall be placed on the planning list. Samples must be collected at least two weeks apart, some time during the ten years preceding the assessment. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New Subsection (1) of Rule 62-320.200, Florida Administrative Code, which is referenced in Subsection (1) of proposed Rule 62-303.340, Florida Administrative Code, defines "acute toxicity." It provides as follows: "Acute Toxicity" shall mean the presence of one or more substances or characteristics or components of substances in amounts which: are greater than one-third (1/3) of the amount lethal to 50% of the test organisms in 96 hours (96 hr LC50) where the 96 hr LC50 is the lowest value which has been determined for a species significant to the indigenous aquatic community; or may reasonably be expected, based upon evaluation by generally accepted scientific methods, to produce effects equal to those of the concentration of the substance specified in (a) above. Subsection (4) of Rule 62-320.200, Florida Administrative Code, which is also referenced in Subsection (1) of proposed Rule 62-303.340, Florida Administrative Code, defines "chronic toxicity." It provides as follows: "Chronic Toxicity" shall mean the presence of one or more substances or characteristics or components of substances in amounts which: are greater than one-twentieth (1/20) of the amount lethal to 50% of the test organisms in 96 hrs (96 hr LC50) where the 96 hr LC50 is the lowest value which has been determined for a species significant to the indigenous aquatic community; or may reasonably be expected, based upon evaluation by generally accepted scientific methods, to produce effects equal to those of the concentration of the substance specified in (a) above. Testing for "acute toxicity" or "chronic toxicity," within the meaning of Subsections (1) and (4) of Rule 62- 320.200, Florida Administrative Code (and therefore proposed Rule 62-303.340, Florida Administrative Code) does not involve measuring the level of any particular parameter in the water sampled. Rather, the tests focus upon the effects the sampled water has on test organisms. Mortality is the end point that characterizes "acute toxicity." "Chronic toxicity" has more subtle effects, which may include reproductive and/or growth impairment. Historically, the Department has tested effluent for "acute toxicity" and "chronic toxicity," but it has not conducted "acute toxicity" or "chronic toxicity" testing in receiving waters. The requirement of Subsections (2) and (3) of proposed Rule 62-303.340, Florida Administrative Code, that test data be no older than ten years old is reasonably designed to make it less likely that a water will be placed on the "planning list" based upon toxicity data not representative of the water's current conditions. Requiring that toxicity be established by at least "two samples" taken "at least two weeks apart" during a "twelve month period," as do Subsections (2) and (3) of proposed Rule 62-303.340, Florida Administrative Code, is also a prudent measure intended to minimize inappropriate listing decisions. To properly determine whether toxicity (which can "change over time") is a continuing problem that may be remedied by TMDL implementation, it is desirable to have more than one sample indicating toxicity. "The judgment was made [by the TAC] that two [samples] would be acceptable to make that determination." The TAC "wanted to include as much data regarding . . . toxicity . . . , and therefore lowered the bar in terms of data sufficiency . . . to only two samples." As noted above, the "minimum criteria for surface waters established in Rule 62-302.500, F.A.C.," which, if not met, will result in a water being placed on the "planning list" pursuant to Subsection (1) of proposed Rule 62-303.300, Florida Administrative Code, include the requirement that surface waters not be "acutely toxic." Whether a water should be placed on the "planning list" because it fails to meet this "minimum criterion" (or "free from") will be determined in light of the provisions of proposed Rule 62-303.340, Florida Administrative Code. Except for "[s]ilver in concentrations above 2.3 micrograms/liter in predominantly marine waters," "acute toxicity" is the only "free from" addressed in any portion of Part II of the proposed rule chapter outside of Subsection (1) of proposed Rule 62-303.300, Florida Administrative Code. Part II: Proposed Rules 62-303.350 through 62-303.353, Florida Administrative Code Proposed Rules 62-303.350 through 62-303.353, Florida Administrative Code, address "nutrients." Nutrients, which consist primarily of nitrogen and phosphorous, stimulate plant growth (and the production of organic materials). Waste water treatment facilities, certain industrial facilities that discharge waste water, phosphate mines, and agricultural and residential lands where fertilizers are used are among the sources of nutrients that affect water bodies in Florida. Nutrients are important to the health of a water body, but when they are present in excessive amounts, problems can arise. Excessive amounts of nutrients can lead to certain species, typically algaes, out-competing native species that are less able to use these nutrients, which, in turn, results in a change in the composition of the aquatic population and, subsequently, the animal population. Factors influencing how a water body responds to nutrient input include location, water body type, ecosystem characteristics, water flow, and the extent of light inhibition. As Mr. Frydenborg testified at the final hearing, nutrients are "probably the most widespread and pervasive cause of environmental disturbance in Florida" and they present "the biggest challenge [that needs to be] overcome in protecting aquatic systems." See also Rule 62-302.300(13), Florida Administrative Code ("The Department finds that excessive nutrients (total nitrogen and total phosphorus) constitute one of the most severe water quality problems facing the State."). As noted above, nutrients are among the parameters for which water quality criteria have been established by the Department in Rule 62-302.530, Florida Administrative Code. The criterion for nutrients set forth in Subsection (48)(b) of the rule (which applies to all "water quality classifications") is a "narrative . . . criterion," as that term is used in Subsection (3)(c) of Section 403.067, Florida Statutes. It is as follows: "In no case shall nutrient concentrations of a body of water be altered as to cause an imbalance of natural populations of aquatic flora or fauna." Proposed Rule 62-303.350, Florida Administrative Code, is entitled, "Interpretation of Narrative Nutrient Criteria," and, as noted in Subsection (4) of proposed Rule 62- 303.310, Florida Administrative Code, "outline[s]" the requirements that must be met for a water to qualify for placement on the "planning list" based upon excessive "nutrient enrichment." It lists Sections 403.061 and 403.067, Florida Statutes, as its "[s]pecific [a]uthority" and Sections 403.062 and 403.067, Florida Statutes, as the "[l]aw [i]mplemented." Subsection (1) of proposed Rule 62-303.350, Florida Administrative Code, reads as follows: Trophic state indices (TSIs) and annual mean chlorophyll a values shall be the primary means for assessing whether a water should be assessed further for nutrient impairment. Other information indicating an imbalance in flora or fauna due to nutrient enrichment, including, but not limited to, algal blooms, excessive macrophyte growth, decrease in the distribution (either in density or areal coverage) of seagrasses or other submerged aquatic vegetation, changes in algal species richness, and excessive diel oxygen swings shall also be considered. Any type of water body (stream, estuary, or lake) may be placed on the "planning list" based upon the "other information" described in the second sentence of Subsection (1) of proposed Rule 62-303.350, Florida Administrative Code. Whether to do so in a particular case will involve the exercise of "best professional judgment" on the part of the Department. The items specifically mentioned in the second sentence of Subsection (1) of proposed Rule 62-303.350, Florida Administrative Code, "[a]lgal blooms, excessive macrophyte growth, decrease in the distribution (either in density or areal coverage) of seagrasses or other submerged aquatic vegetation,46 changes in algal species richness, and excessive diel oxygen swings," are all indicators of excessive "nutrient enrichment." The "but not limited to" language in this sentence makes it abundantly clear that this is not an exhaustive listing of "other information indicating an imbalance in flora or fauna due to nutrient enrichment" that will be considered by the Department in determining whether a water should be placed on the "planning list." During the rule development process, there were a number of members of the public who expressed the view that the Department's possession of the "information" described in the second sentence of Subsection (1) of proposed Rule 62-303.350, Florida Administrative Code, should be the sole basis for determining "nutrient impairment" and that TSIs and annual mean chlorophyll a values should not be used. Department staff rejected these suggestions and drafted the proposed rule chapter to provide for additional ways, using TSIs and annual mean chlorophyll a values, for a water to make the "planning list" based upon excessive "nutrient enrichment." Chlorophyll a is the photosynthetic pigment in algae. Measuring chlorophyll a concentrations in water is a reasonable surrogate for measuring the amount of algal biomass present (which is indicative of the extent of nutrient enrichment inasmuch as nutrients promote algal growth). Chlorophyll a values, expressed in micrograms per liter, reflect the concentration of suspended algae (phytoplankton) in the water.47 High amounts of chlorophyll a indicate that there have been algal blooms. Algal blooms represent significant increases in algal population (phytoplankton) over a short period of time. They have a deleterious effect on the amount of dissolved oxygen in the water. Algal blooms may occur in any season. There are no adequate means to predict when they will occur. An annual mean chlorophyll a value reflects the level of nutrient enrichment occurring in a water over the course of a year. Biologists look at these values when studying the productivity of aquatic systems. Using an annual mean is the "best way" of determining whether nutrient enrichment is a consistent enough problem to cause an imbalance in flora or fauna. The TSI was developed for the Department's use in preparing 305(b) Reports. It is a "tried and true method" of assessing lakes (and only lakes) for "nutrient impairment." No comparable special index exists for other types of water bodies in this state. TSI values are derived from annual mean chlorophyll a, as well as nitrogen and phosphorous, values (which are composited). The process of "[c]alculating the Trophic State Index for lakes" was described in the "State's 1996 305(b) report" (on page 86) as follows: The Trophic State Index effectively classifies lakes based on their chlorophyll levels and nitrogen and phosphorous concentrations. Based on a classification scheme developed in 1977 by R.E. Carlson, the index relies on three indicators-- Secchi depth, chlorophyll, and total phosphorous-- to describe a lake's trophic state. A ten unit change in the index represents a doubling or halving or algal biomass. The Florida Trophic State Index is based on the same rationale but also includes total nitrogen as a third indicator. Attempts in previous 305(b) reports to include Secchi depth have caused problems in dark-water lakes and estuaries, where dark waters rather than algae diminish transparency. For this reason, our report drops Secchi depth as a category. We developed Florida lake criteria from a regression analysis of data on 313 Florida lakes. The desirable upper limit for the index is 20 micrograms per liter of chlorophyll, which corresponds to an index of 60. Doubling the chlorophyll concentration to 40 micrograms per liter increases the index to 70, which is the cutoff for undesirable (or poor) lake quality. Index values from 60 to 69 represent fair water quality. . . . The Nutrient Trophic State Index is based on phosphorous and nitrogen concentrations and the limiting nutrient concept. The latter identifies a lake as phosphorous limited if the nitrogen-to-phosphorous concentration ratio is greater than 30, nitrogen limited if the ratio is less than 10, and balanced (depending on both nitrogen and phosphorous) if the ratio is 10 to 30. The nutrient ratio is thus based solely on phosphorous if the ratio is greater than 30, solely on nitrogen if less than 10, or on both nitrogen and phosphorous if between 10 and 30. We calculated an overall Trophic State Index based on the average of the chlorophyll and nutrient indices. Calculating an overall index value requires both nitrogen and phosphorous measurements. Subsections (2) and (3) of proposed Rule 62-303.350, Florida Administrative Code, which provide as follows, impose reasonable data sufficiency and quality requirements for calculating TSIs and annual mean chlorophyll a values and changes in those values from "historical levels": To be used to determine whether a water should be assessed further for nutrient enrichment, data must meet the requirements of paragraphs (2)-(4), (6), and (7) in rule 62- 303.320, at least one sample from each season shall be required in any given year to calculate a Trophic State Index (TSI) or an annual mean chlorophyll a value for that year, and there must be annual means from at least four years, when evaluating the change in TSI over time pursuant to paragraph 62- 303.352(3). When comparing changes in chlorophyll a or TSI values to historical levels, historical levels shall be based on the lowest five-year average for the period of record. To calculate a five-year average, there must be annual means from at least three years of the five-year period. These requirements do not apply to the "other information" referenced in the second sentence of Subsection (1) of proposed Rule 62-303.350, Florida Administrative Code. As was stated in the NRC Publication, and as Department staff recognized, "data are not the same as information." Subsection (2)(b) of proposed Rule 62-303.350, Florida Administrative Code, being more specific, modifies Subsection (2)(a) of the proposed rule, to the extent that Subsection (2)(a) incorporates by reference the requirement of Subsection (4) of proposed Rule 62-303.320, Florida Administrative Code, that "at least one sampling event [be] conducted in [only] three of the four seasons of the calendar year." Requiring data from at least each season is appropriate because the data will be used to arrive at numbers that represent annual means. Furthermore, as noted above, there is no season in which bloom events never occur in this state. Four years of data, as required by Subsection (2)(c) of proposed Rule 62-303.350, Florida Administrative Code, establishes a "genuine trend" in the TSI. The requirement, in Subsection (2)(c) of proposed Rule 62-303.350, Florida Administrative Code, that the "lowest five-year average for the period of the record" be used to establish "historical levels" was intended to make it easier for a water to be placed on the "planning list" for "nutrient impairment." 190. Proposed Rules 62-303.351, 62-303.352, and 62- 303.353, Florida Administrative Code, establish reasonable statewide TSI and annual mean chlorophyll a values, which if exceeded, will result in a water being placed on the "planning list."48 In establishing these statewide threshold values, Department staff took into consideration that averaging values obtained from samples taken during bloom events with lower values obtained from other samples taken during the course of the year (to get an annual mean value for a water) would minimize the impact of the higher values and, accordingly, they set the thresholds at levels lower than they would have if the thresholds represented, not annual mean values, but rather values that single samples, evaluated individually, could not exceed. Department staff recognized that the statewide thresholds they set "may not be protective of very low nutrient waters." They therefore, in proposed Rules 62-303.351, 62- 303.352, and 62-303.353, Florida Administrative Code, reasonably provided that waters not exceeding these thresholds could nonetheless get on the "planning list" for "nutrient impairment" based upon TSI values (in the case of lakes) or annual mean chlorophyll a values (in the case of streams and estuaries) if these values represented increases, of sufficient magnitude, as specified in the proposed rules, over "historical levels." Proposed Rule 62-303.351, Florida Administrative Code, is entitled, "Nutrients in Streams," and reads as follows: A stream or stream segment shall be included on the planning list for nutrients if the following biological imbalances are observed: algal mats are present in sufficient quantities to pose a nuisance or hinder reproduction of a threatened or endangered species, or annual mean chlorophyll a concentrations are greater than 20 ug/l or if data indicate annual mean chlorophyll a values have increased by more than 50% over historical values for at least two consecutive years. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New The TAC and Department staff investigated the possibility of evaluating "nutrient impairment" in streams by looking at the amount of attached algae (measured in milligrams of chlorophyll a per square meter) as opposed to suspended algae, but "weren't able to come up with" an appropriate "number." They were advised of a "paper" in which the author concluded that 150 milligrams of chlorophyll a per square meter was "indicative of imbalances in more northern conditions rivers." Reviewing Florida data, the TAC and Department staff determined that this threshold would be "non-protective in our state" inasmuch as the "the highest chlorophylls" in the Florida data they reviewed were 50 to 60 milligrams of chlorophyll a per square meter. Subsection (1) of proposed Rule 62-303.351, Florida Administrative Code, which describes, in narrative terms, another type of "information indicating an imbalance in flora or fauna due to nutrient enrichment" (in addition to those types of information specified in Subsection (1) of proposed Rule 62- 303.350, Florida Administrative Code), was included in proposed Rule 62-303.351 in lieu of establishing a numerical "milligrams of chlorophyll a per square meter" threshold. The term "nuisance," as used in Subsection (1) of proposed Rule 62-303.351, Florida Administrative Code, was intended to have the same meaning as it has in Rule 62-302.500, Florida Administrative Code. "Nuisance species," as used in Rule Chapter 62-500, Florida Administrative Code, are defined as "species of flora or fauna whose noxious characteristics or presence in sufficient number, biomass, or areal extent may reasonably be expected to prevent, or unreasonably interfere with, a designated use of those waters." Mr. Joyner knew that the Suwannee River "had problems with algal mats49 and that those algal mats might hinder reproduction of the sturgeon" in the river. The "hinder reproduction of a threatened or endangered species" language was inserted in Subsection (1) of proposed Rule 62-303.351, Florida Administrative Code, "to address things like that" occurring in the Suwannee River. It was "very difficult" for the TAC and Department staff to come up with a "micrograms per liter" threshold for Subsection (2) of proposed Rule 62-303.351, Florida Administrative Code. All available data on Florida streams were reviewed before the TAC and Department staff decided on a threshold. The threshold ultimately selected, 20 micrograms per liter, "represents approximately the 80th percentile value currently found in Florida streams," according to the data reviewed. The "20 micrograms per liter" threshold, combined with the other provisions of the proposed rule and the second sentence of proposed Rule 62-303.350, Florida Administrative Code, was "thought to be something that would hold the line on future [nutrient] enrichment," particularly with respect to streams "like the lower St. Johns River which tends to act more like a lake." Anything over 20 micrograms per liter of chlorophyll a "is a clear indication that an imbalanced situation is occurring." There are some streams in Florida that have high nutrient concentrations but, because of flow conditions and water color, also have low levels of chlorophyll a in the water column (reflecting that the nutrients' presence in the water has not resulted in significant algal growth). That these streams would not qualify for placement on the "planning list" pursuant to proposed Rule 62-303.351, Florida Administrative Code, as drafted, did not concern the TAC and Department staff because they thought it appropriate "to focus on [the] realized impairment" caused by nutrients, not on their mere presence in the stream. If these nutrients travel downstream and adversely affect the downstream water to such an extent that the downstream water qualifies for a TMDL, "all the sources upstream would be addressed" in the TMDL developed for the downstream water. Pursuant to Subsection (2) of proposed Rule 62- 303.351, Florida Administrative Code, streams with "very, very low chlorophylls," well under 20 micrograms per liter, can nonetheless qualify for placement on the planning list based upon two consecutive years of increased annual mean chlorophyll a values "over historical values." In the case of a stream with "historical values" of two micrograms per liter, for instance, the increase would need to be only more than one microgram per liter. Proposed Rule 62-303.352, Florida Administrative Code, is entitled, "Nutrients in Lakes," and reads as follows: For the purposes of evaluating nutrient enrichment in lakes, TSIs shall be calculated based on the procedures outlined on pages 86 and 87 of the State's 1996 305(b) report, which are incorporated by reference. Lakes or lake segments shall be included on the planning list for nutrients if: For lakes with a mean color greater than 40 platinum cobalt units, the annual mean TSI for the lake exceeds 60, unless paleolimnological information indicates the lake was naturally greater than 60, or For lakes with a mean color less than or equal to 40 platinum cobalt units, the annual mean TSI for the lake exceeds 40, unless paleolimnological information indicates the lake was naturally greater than 40, or For any lake, data indicate that annual mean TSIs have increased over the assessment period, as indicated by a positive slope in the means plotted versus time, or the annual mean TSI has increased by more than 10 units over historical values. When evaluating the slope of mean TSIs over time, the Department shall use a Mann's one-sided, upper-tail test for trend, as described in Nonparametric Statistical Methods by M. Hollander and D. Wolfe 16 (1999 ed.), pages 376 and 724 (which are incorporated by reference), with a 95% confidence level. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New As noted above, a TSI value of 60, the threshold established in Subsection (1) of proposed Rule 62-303.352, Florida Administrative Code, for darker-colored lakes, is the equivalent of a chlorophyll a value of 20 micrograms per liter, which is the "micrograms per liter" threshold for streams established in Subsection (2) of proposed Rule 62-303.351, Florida Administrative Code. A TSI value 40, the threshold established in Subsection (2) of proposed Rule 62-303.352, Florida Administrative Code, for lighter-colored lakes, corresponds to a chlorophyll a value of five micrograms per liter, which "is an extremely low level." A TSI value of 40 is "very protective for that particular category of lake[s]." A lower threshold was established for these lighter- colored lakes (having a mean color less than or equal to 40 platinum cobalt units) because it was felt that these lakes needed "extra protection." Providing such "extra protection" is reasonably justified inasmuch as these lakes (due to their not experiencing the "infusion of leaf litter" that affects darker- colored lakes) tend to have a "lower nutrient content naturally" and therefore "very different aquatic communities" than their darker counterparts. Some lakes are naturally eutrophic or even hyper- eutrophic. Inasmuch as the TMDL program is not designed to address such natural occurrences, it makes sense to provide, as Subsections (1) and (2) of proposed Rule 62-303.352, Florida Administrative Code, do, that the TSI thresholds established therein will not apply if "paleolimnological information" indicates that the TSI of the lake in question was "naturally greater" than the threshold established for that type of lake (60 in the case of a darker-colored lake and 40 in the case of a lighter-colored lake). Lakes with TSI values that do not exceed the appropriate threshold may nonetheless be included on the "planning list" based upon "increas[es] in TSIs" pursuant to Subsection (3) of proposed Rule 62-303.352, Florida Administrative Code. Any statistically significant increase in TSI values "over the assessment period," as determined by "use [of] a Mann's one-sided, upper-tail test for trend" and a "95% confidence level" (which the TAC recommended inasmuch as it is "the more typical scientific confidence level"), or an increase in the annual mean TSI of more than ten units "over historical values," will result in a lake being listed pursuant to Subsection (3) of proposed Rule 62-303.352, Florida Administrative Code. The first of these two alternative ways of a lake getting on the "planning list" based upon "increas[es] in TSIs" is "more protective" than the second. Under this first alternative, a lake could be listed before there was more than a ten unit increase in the annual mean TSI "over historical values." A ten-unit increase in the annual mean TSI represents a doubling (or 100 percent increase) "over historical values." As noted above, pursuant to Subsection (3) of proposed Rule 62- 303.351, Florida Administrative Code, only a 50 percent increase "over historical values" in annual mean chlorophyll a values is needed for a stream to make the "planning list" and, as will be seen, proposed Rule 62-303.353, Florida Administrative Code, contains a similar "50 percent increase" provision for estuaries; however, because "lakes are much more responsive to nutrients," Department staff reasonably believed that "the ten- unit change was a protective measure." Proposed Rule 62-303.353, Florida Administrative Code, is entitled, "Nutrients in Estuaries," and reads as follows: Estuaries or estuary segments shall be included on the planning list for nutrients if their annual mean chlorophyll a for any year is greater than 11 ug/l or if data indicate annual mean chlorophyll a values have increased by more than 50% over historical values for at least two consecutive years. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New Estuaries are at "the very bottom" of the watershed. The amount of nutrients in an estuary is dependent, not only on what is occurring in and around the immediate vicinity of the estuary,50 but also "what is coming down" any river flowing into it. Not all of the nutrients in the watershed reach the estuary inasmuch as "there is assimilation and uptake along the way." The "11 micrograms per liter" threshold ultimately selected as a "protective number in terms of placing estuaries on the 'planning list'" was recommended by the TAC following a review of data reflecting trends with respect to chlorophyll a levels in various Florida estuaries. In addition, the TAC heard a presentation concerning the "modeling work" done by the Tampa Bay National Estuary Program to establish "site-specific" chlorophyll a targets for segments of Tampa Bay, including the target of 13.2 micrograms per liter that was established for the Hillsborough Bay segment of Tampa Bay, which is "closer to the [nutrient] sources" than other parts of Tampa Bay. The TAC also considered information about "various bloom situations" in estuaries which led to the "general feeling" that an estuarine algal bloom involved chlorophyll a values "considerably higher" than 11 micrograms per liter. An alternative method for an estuary to make the "planning list" for "nutrient impairment" based upon a 50 percent increase in annual mean chlorophyll a values "over historical values" was included in proposed Rule 62-303.353, Florida Administrative Code, because the "11 micrograms per liter" threshold was not expected "to be adequately protect[ive]" of "the very clear sea grass communities" like those found in the Florida Keys. Part II: Proposed Rule 62-303.360, Florida Administrative Code Proposed Rule 62-303.360, Florida Administrative Code, establishes four separate ways for a water to be placed on the "planning list" for failing to provide "primary contact and recreation use support." It reads as follows: Primary Contact and Recreation Use Support A Class I, II, or III water shall be placed on the planning list for primary contact and recreation use support if: the water segment does not meet the applicable water quality criteria for bacteriological quality based on the methodology described in section 62-303.320, or the water segment includes a bathing area that was closed by a local health Department or county government for more than one week or more than once during a calendar year based on bacteriological data, or the water segment includes a bathing area for which a local health Department or county government has issued closures, advisories, or warnings totaling 21 days or more during a calendar year based on bacteriological data, or the water segment includes a bathing area that was closed or had advisories or warnings for more than 12 weeks during a calendar year based on previous bacteriological data or on derived relationships between bacteria levels and rainfall or flow. For data collected after August 1, 2000, the Florida Department of Health (DoH) database shall be the primary source of data used for determining bathing area closures. Advisories, warnings, and closures based on red tides, rip tides, sewage spills, sharks, medical wastes, hurricanes, or other factors not related to chronic discharges of pollutants shall not be included when assessing recreation use support. However, the Department shall note for the record that data were excluded and explain why they were excluded. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New The "water quality criteria for bacteriological quality" referenced in Subsection (1)(a) of proposed Rule 62- 303.360, Florida Administrative Code, are set forth in Subsections (6) and (7) of Rule 62-303.530, Florida Administrative Code, which provide as follows: Parameter: Bacteriological Quality (Fecal Coliform Bacteria) Units: Number per 100 ml (Most Probable Number (MPN) or Membrane Filter (MF)) Class I: MPN or MF counts shall not exceed a monthly average of 200, nor exceed 400 in 10% of the samples, nor exceed 800 on any one day. Monthly averages shall be expressed as geometric means based on a minimum of 5 samples taken over a 30 day period. Class II: MPN shall not exceed a median value of 14 with not more than 10% of the samples exceeding 43, nor exceed 800 on any one day. Class III: Fresh: MPN or MF counts shall not exceed a monthly average of 200, nor exceed 400 in 10% of the samples, nor exceed 800 on any one day. Monthly averages shall be expressed as geometric means based on a minimum of 10 samples taken over a 30 day period. Class III: Marine: MPN or MF counts shall not exceed a monthly average of 200, nor exceed 400 in 10% of the samples, nor exceed 800 on any one day. Monthly averages shall be expressed as geometric means based on a minimum of 10 samples taken over a 30 day period. Parameter: Bacteriological Quality (Total Coliform Bacteria) Units: Number per 100 ml (Most Probable Number (MPN) or Membrane Filter (MF)) Class I: < = 1,000 as a monthly avg., nor exceed 1,000 in more than 20% of samples examined during any month, nor exceed 2,400 at any time using either MPN or MF counts. Class II: Median MPN shall not exceed 70 and not more than 10% of the samples shall exceed an MPN of 230. Class III: Fresh: < = 1,000 as a monthly average, nor exceed 1,000 in more than 20% of samples examined during any month, < = 2,400 at any time. Monthly averages shall be expressed as geometric means based on a minimum or 10 samples taken over a 30 day period, using either the MPN or MF counts. Class III: Marine: < = 1,000 as a monthly average, nor exceed 1,000 in more than 20% of samples examined during any month, < = 2,400 at any time. Monthly averages shall be expressed as geometric means based on a minimum or 10 samples taken over a 30 day period, using either the MPN or MF counts. Fecal coliform bacteria are found in the feces of animals and humans. They can be identified in the laboratory "fairly easily, usually within 24 to 48 hours" and "are used worldwide as indicators of fecal contamination and potential public health risks." Enterococci are another "distinct group of bacteria." They too are found in animal and human feces. The recommendation has been made that enterococci be used as bacteriological "indicators" for assessing "public health risk and swimmability," particularly in marine waters. The Department, however, is not convinced that there is "sufficient science at this time" to warrant adoption of this recommendation in states, like Florida, with "warmer climates," and it has not amended Rule 62-303.530, Florida Administrative Code, to provide for the assessment of bacteriological quality using enterococci counts.51 The statistical "methodology described in [proposed Rule] 62-303.320," Florida Administrative Code (which is incorporated by reference in Subsection (1)(a) of proposed Rule 62-303.360, Florida Administrative Code) is as appropriate for determining whether a water should be placed on the "planning list" based upon exceedances of bacteriological water quality criteria as it is for determining whether a water should be placed on the "planning list" for "[e]xceedances of [a]quatic [l]ife-[b]ased [c]riteria." Unlike Subsection (1)(a) of proposed Rule 62-303.360, Florida Administrative Code, Subsections (1)(b), (1)(c), and (1)(d) of the proposed rule, at least indirectly, allow for waters to be placed on the "planning list" based upon enterococci counts. The closures, advisories, and warnings referenced in Subsections (1)(b), (1)(c), and (1)(d) of proposed Rule 62- 303.360, Florida Administrative Code, are issued, not by the Department, but by local health departments or county governments, and may be based upon enterococci sampling done by those governmental entities. Subsection (1)(b) of proposed Rule 62-303.360, Florida Administrative Code, provides for listing based exclusively upon bathing area closures. It was included in the proposed rule upon the recommendation of the EPA "to track their 305(b) guidance." Both freshwater and marine bathing areas in Florida may be closed if circumstances warrant. The Department of Health (which operates the various county health departments) does not close marine beaches, but county governments may. Subsection (1)(c) of proposed Rule 62-303.360, Florida Administrative Code, provides for listing based upon any combination of closures, advisories, or warnings "totaling 21 days or more during a calendar year," provided the closures, advisories, and warnings were based upon up-to-date "bacteriological data." Department staff included this provision in the proposed rule in lieu of a provision recommended by the TAC (about which Petitioner Young had expressed concerns) that would have made it more difficult for a water to be placed on the "planning list" as a result of bacteriological data-based closures, advisories, or warnings. In doing so, Department staff exercised sound professional judgment. The 21 days or more of closures, advisories, or warnings needed for listing under the proposed rule do not have to be consecutive, although they all must occur in the same calendar year. Subsection (1)(d) of proposed Rule 62-303.360, Florida Administrative Code, like Subsection (1)(c) of the proposed rule, provides for listing based upon a combination of closures, advisories, or warnings, but it does not require that it be shown that the closures, advisories, or warnings were based upon up-to-date "bacteriological data." Under Subsection (1)(d) of the proposed rule, the closures, advisories, or warnings need only have been based upon "previous [or, in other words, historical] bacteriological data" or "derived relationships between bacteria levels and rainfall or flow." Because assessments of current bacteriological quality based upon "previous bacteriological data" or on "derived relationships between bacteria levels and rainfall or flow" are less reliable than those based upon up-to-date "bacteriological data," Department staff were reasonably justified in requiring a greater total number of days of closures, advisories, or warnings in this subsection of the proposed rule (more than 84) than they did in Subsection (1)(c) of the proposed rule (more than 21). (Like under Subsection (1)(c) of the proposed rule, the days of closures, advisories, or warnings required for listing under Subsection (1)(d) of the proposed rule do not have to be consecutive days.) Subsection (1)(d) was included in the proposed rule in response to comments made at a TAC meeting by Mike Flannery of the Pinellas County Health Department concerning Pinellas County beaches that were "left closed for long periods of time" without follow-up bacteriological testing. Subsection (3) of proposed Rule 62-303.360, Florida Administrative Code, reasonably limits the closures, advisories, and warnings upon which the Department will be able to rely in determining whether a water should be placed on the "planning list" pursuant to Subsections (1)(b), (1)(c), or (1)(d) of the proposed rule to those closures, advisories, and warnings based upon "factors . . . related to chronic discharges of pollutants." The TMDL program is designed to deal neither with short-term water quality problems caused by extraordinary events that result in atypical conditions,52 nor with water quality problems unrelated to pollutant discharges in this state. It is therefore sensible to not count, for purposes of determining "planning list" eligibility pursuant to Subsections (1)(b), (1)(c), or (1)(d) of proposed Rule 62-303.360, Florida Administrative Code, closures, advisories, and warnings that were issued because of the occurrence of such problems. A "spill," by definition (set out in Subsection (16) of proposed Rule 62-303.200, Florida Administrative Code, which is recited above), is a "short term" event that does not include "sanitary sewer overflows or chronic discharges from leaking wastewater collection systems." While a one-time, unpermitted discharge of sewage (not attributable to "sanitary sewer overflow") is a "short- term" event constituting a "sewage spill," as that term is used in Subsection (3) of proposed Rule 62-303.360, Florida Administrative Code, repeated unpermitted discharges occurring over an extended period of time (with or without interruption) do not qualify as "sewage spills" and therefore Subsection (3) of the proposed rule will not prevent the Department from considering closures, advisories, and warnings based upon such discharges in deciding whether the requirements for listing set forth in Subsections (1)(b), (1)(c), or (1)(d) of the proposed rule have been met. Like "sewage spills," "red tides" are among the events specifically mentioned in Subsection (3) of proposed Rule 62-303.360, Florida Administrative Code. "Red tide" is a "very loose term" that can describe a variety of occurrences. It is apparent from a reading of the language in Subsection (3) of proposed Rule 62-303.360, Florida Administrative Code, in its entirety, that "red tide," as used therein, was intended to describe an event "not related to chronic discharges of pollutants." Department staff's understanding of "red tides" was shaped by comments made at a TAC meeting by one of the TAC members, George Henderson of the Florida Marine Research Institute. Mr. Henderson told those present at the meeting that "red tides are an offshore phenomenon that move on shore" and are fueled by nutrients from "unknown sources" likely located, for the most part, outside of Florida, in and around the Mississippi River. No "contrary scientific information" was offered during the rule development process.53 Lacking "scientific information" clearly establishing that "red tides," as they understood the term, were the product of "pollutant sources in Florida," Department staff reasonably concluded that closures, advisories, and warnings based upon such "red tides" should not be taken into consideration in deciding whether a water should be placed on the "planning list" pursuant to Subsections (1)(b), (1)(c), or (1)(d) of proposed Rule 62- 303.360, Florida Administrative Code, and they included language in Subsection (3) of the proposed rule to so provide. The "red tides" to which Mr. Henderson referred are harmful algae blooms that form off-shore in the Gulf of Mexico and are brought into Florida coastal waters by the wind and currents. There appears to be an association between these blooms of toxin-producing algae and nutrient enrichment, but the precise cause of these bloom events is "not completely understood." Scientists have not eliminated the possibility that, at least in some instances, these "red tides" are natural phenomena not the result of any pollutant loading either in or outside of Florida. The uncertainty surrounding the exact role, if any, that Florida-discharged pollutants play in the occurrence of the "red tides" referenced in Subsection (3) of proposed Rule 62-303.360, Florida Administrative Code, reasonably justifies the Department's declining, for purposes of determining whether the listing requirements of Subsections (1)(b), (1)(c), or (1)(d) of the proposed rule have been met, to take into consideration closures, advisories, and warnings based upon such "red tides." The exclusions contained in Subsection (3) of proposed Rule 62-303.360, Florida Administrative Code, will have no effect on the "information" or "data" that the Department will be able to consider under any provision in Part II of the proposed rule chapter other than Subsections (1)(b), (1)(c), and (1)(d) of proposed Rule 62-303.360. This includes the provisions of proposed Rule 62-303.350, Florida Administrative Code, which, as noted above, provides, among other things, that "planning list" eligibility may be based upon "information indicating an imbalance in flora or fauna due to nutrient enrichment, including . . . algal blooms." Accordingly, notwithstanding the "red tides" exclusion in Subsection (3) of proposed Rule 62-303.360, Florida Administrative Code, the presence of algal blooms of any type "indicating an imbalance in flora or fauna due to nutrient enrichment" will result in the affected water making the "planning list" pursuant to proposed Rule 62-303.350, Florida Administrative Code, to be "assessed further for nutrient impairment." Part II: Proposed Rule 62-303.370, Florida Administrative Code Proposed Rule 62-303.370, Florida Administrative Code, provides three separate ways for a water to "be placed on the planning list for fish and shellfish consumption." It reads as follows: Fish and Shellfish Consumption Use Support A Class I, II, or III water shall be placed on the planning list for fish and shellfish consumption if: the water segment does not meet the applicable Class II water quality criteria for bacteriological quality based on the methodology described in section 62-303.320, or there is either a limited or no consumption fish consumption advisory. issued by the DoH, or other authorized governmental entity, in effect for the water segment, or for Class II waters, the water segment includes an area that has been approved for shellfish harvesting by the Shellfish Evaluation and Assessment Program, but which has been downgraded from its initial harvesting classification to a more restrictive classification. Changes in harvesting classification from prohibited to unclassified do not constitute a downgrade in classification. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New Subsection (1) of proposed Rule 62-303.370, Florida Administrative Code, which effectively duplicates the provisions of Subsection (1)(a) of proposed Rule 62-303.360, Florida Administrative Code, to the extent that those provisions apply to Class II waters, establishes an appropriate means of determining whether a water should "be placed on the planning list for fish and shellfish consumption." Waters that do not qualify for listing pursuant to Subsection (1) of proposed Rule 62-303.370, Florida Administrative Code, may make the "planning list" based upon "fish consumption advisories" under Subsection (2) of the proposed rule. The Department of Health, which issues these advisories, does so after conducting a statistical evaluation of fish tissue data collected from at least 12 fish. A large number of fish consumption advisories have been issued to date for a number of parameters, including, most significantly, mercury. The first fish consumption advisory was issued in 1989 after "high levels of mercury" were found in the sampled fish tissue. Many fish consumption advisories were issued ten or more years ago and are still in effect. Fish consumption advisories are continued until it is shown that they are not needed. Most of the fish tissue data for the fish consumption advisories now in effect were collected between 1989 and 1992. There is no reason to reject this data as not "being representative of the conditions under which those samples were collected." There has been data collected since 1992, but 1992 was "the last peak year" of sampling. Over the last ten years, the "focus has been on the Everglades" with respect to sampling for mercury, although sampling has occurred in "a broadly representative suite of water bodies statewide." The TAC recommended against using fish consumption advisories for listing coastal and marine waters because of the possibility that these advisories might be based upon tissue samples taken from fish who ingested mercury, or other substances being sampled, outside of the state. Department staff, however, rejected this recommendation and did not include a "coastal and marine waters" exclusion in Subsection (2) of proposed Rule 62-303.370, Florida Administrative Code. The Shellfish Evaluation and Assessment Program, which is referenced in Subsection (3) of proposed Rule 62- 303.370, Florida Administrative Code, is administered by the Florida Department of Agriculture and Consumer Services' Division of Aquaculture's Shellfish Environmental Assessment Section. The Shellfish Environmental Assessment Section (SEAS) is responsible for classifying and managing Florida shellfish harvesting areas in a manner that maximizes utilization of the state's shellfish resources and reduces the risk of shellfish- borne illness. In carrying out its responsibilities, the SEAS applies the "[s]hellfish [h]arvesting [a]rea [s]tandards" set forth in Rule 5L-1.003, Florida Administrative Code, which provides as follows: The Department shall describe and/or illustrate harvesting areas and provide harvesting area classifications as approved, conditionally approved, restricted, conditionally restricted, prohibited, or unclassified as defined herein, including criteria for opening and closing shellfish harvesting areas in accordance with Chapters II and IV of the National Shellfish Sanitation Program Model Ordinance. Copies of the document Shellfish Harvesting Area Classification Maps, revised October 14, 2001, and the document Shellfish Harvesting Area Classification Boundaries and Management Plans, revised October 14, 2001, containing shellfish harvesting area descriptions, references to shellfish harvesting area map numbers, and operating criteria herein incorporated by reference may be obtained by writing to the Department at 1203 Governors Square Boulevard, 5th Floor, Tallahassee, Florida 32301. Approved areas -- Growing areas shall be classified as approved when a sanitary survey, conducted in accordance with Chapter IV of the National Shellfish Sanitation Program Model Ordinance, indicates that pathogenic microorganisms, radionuclides, and/or harmful industrial wastes do not reach the area in dangerous concentrations and this is verified by laboratory findings whenever the sanitary survey indicates the need. Shellfish may be harvested from such areas for direct marketing. This classification is based on the following criteria: The area is not so contaminated with fecal material or poisonous or deleterious substances that consumption of the shellfish might be hazardous; and The bacteriological quality of every sampling station in those portions of the area most probably exposed to fecal contamination shall meet one of the following standards during the most unfavorable meteorological, hydrographic, seasonal, and point source pollution conditions: 1) The median or geometric mean fecal coliform Most Probable Number (MPN) of water shall not exceed 14 per 100 ml., and not more than 10 percent of the samples shall exceed a fecal coliform MPN of 43 per 100 ml. (per 5-tube, 3-dilution test) or 2) The median or geometric mean fecal coliform Most Probable Number (MPN) of water shall not exceed 14 per 100 ml., and not more than 10 percent of the samples shall exceed a fecal coliform MPN of 33 per 100 ml. (per 12-tube, single-dilution test). Harvest from temporarily closed approved areas shall be unlawful. Conditionally approved areas -- A growing area shall be classified as conditionally approved when a sanitary survey, conducted in accordance with Chapter IV of the National Shellfish Sanitation Program Model Ordinance, indicates that the area is subjected to intermittent microbiological pollution. The suitability of such an area for harvesting shellfish for direct marketing may be dependent upon attainment of established performance standards by wastewater treatment facilities discharging effluent directly or indirectly into the area. In other instances, the sanitary quality of the area may be affected by seasonal populations, climatic and/or hydrographic conditions, non-point source pollution, or sporadic use of a dock, marina, or harbor facility. Such areas shall be managed by an operating procedure that will assure that shellfish from the area are not harvested from waters not meeting approved area criteria. In order to develop effective operating procedures, these intermittent pollution events shall be predictable. Harvest from temporarily closed conditionally approved areas shall be unlawful. Restricted areas -- A growing area shall be classified as restricted when a sanitary survey, conducted in accordance with Chapter IV of the National Shellfish Sanitation Program Model Ordinance, indicates that fecal material, pathogenic microorganisms, radionuclides, harmful chemicals, and marine biotoxins are not present in dangerous concentrations after shellfish from such an area are subjected to a suitable and effective purification process. The bacteriological quality of every sampling station in those portions of the area most probably exposed to fecal contamination shall meet the following standard: The median or geometric mean fecal coliform Most Probable Number (MPN) of water shall not exceed 88 per 100 ml. and not more than 10 percent of the samples shall exceed a fecal coliform MPN of 260 per 100 ml. (per 5-tube, 3-dilution test) in those portions of the area most probably exposed to fecal contamination during the most unfavorable meteorological, hydrographic, seasonal, and point source pollution conditions. Harvest is permitted according to permit conditions specified in Rule 5L-1.009, F.A.C. Harvest from temporarily closed restricted areas shall be unlawful. Conditionally restricted area -- A growing area shall be classified as conditionally restricted when a sanitary survey or other monitoring program data, conducted in accordance with Chapter IV of the National Shellfish Sanitation Program Model Ordinance, indicates that the area is subjected to intermittent microbiological pollution. The suitability of such an area for harvest of shellfish for relaying or depuration activities is dependent upon the attainment of established performance standards by wastewater treatment facilities discharging effluent, directly or indirectly, into the area. In other instances, the sanitary quality of such an area may be affected by seasonal population, non-point sources of pollution, or sporadic use of a dock, marina, or harbor facility, and these intermittent pollution events are predictable. Such areas shall be managed by an operating procedure that will assure that shellfish from the area are not harvested from waters not meeting restricted area criteria. Harvest is permitted according to permit conditions specified in Rule 5L- 1.009, F.A.C. Harvest from temporarily closed conditionally restricted areas shall be unlawful. Prohibited area -- A growing area shall be classified as prohibited if a sanitary survey indicates that the area does not meet the approved, conditionally approved, restricted, or conditionally restricted classifications. Harvest of shellfish from such areas shall be unlawful. The waters of all man-made canals and marinas are classified prohibited regardless of their location. Unclassified area -- A growing area for which no recent sanitary survey exists, and it has not been classified as any area described in subsections (2), (3), (4), (5), or (6) above. Harvest of shellfish from such areas shall be unlawful. Approved or conditionally approved, restricted, or conditionally restricted waters shall be temporarily closed to the harvesting of shellfish when counts of the red tide organism Gymnodinium breve[54] exceed 5000 cells per liter in bays, estuaries, passes or inlets adjacent to shellfish harvesting areas. Areas closed to harvesting because of presence of the red tide organism shall not be reopened until counts are less than or equal to 5000 cells per liter inshore and offshore of the affected shellfish harvesting area, and shellfish meats have been shown to be free of toxin by laboratory analysis. The Department is authorized to open and temporarily close approved, conditionally approved, restricted, or conditionally restricted waters for harvesting of shellfish in emergencies as defined herein, in accordance with specific criteria established in operating procedures for predictively closing individual growing areas, or when growing areas do not meet the standards and guidelines established by the National Shellfish Sanitation Program . Operating procedures for predictively closing each growing area shall be developed by the Department; local agencies, including those responsible for operation of sewerage systems, and the local shellfish industry may be consulted for technical information during operating procedure development. The predictive procedure shall be based on evaluation of potential sources of pollution which may affect the area and should establish performance standards, specify necessary safety devices and measures, and define inspection and check procedures. Under Subsection (3) of proposed Rule 62-303.370, Florida Administrative Code, only the "downgrading" of an area initially approved for shellfish harvesting to a more restrictive classification will cause a Class II water to be "placed on the planning list for fish and shellfish consumption." The temporary closure of an approved harvesting area will not have the same result. Temporary closures of harvesting areas are not uncommon. These closures typically occur when there is heavy local rainfall or flooding events upstream, which result in high fecal coliform counts in the harvesting areas. While these areas are not being harvested during these temporary closures, "[p]ropagation is probably maximized in closure conditions." This is because, during these periods, there are "more nutrients for [the shellfish] to consume" inasmuch as the same natural events that cause fecal coliform counts to increase also bring the nutrients (in the form detritus) into the area. The Department of Agriculture and Consumer Services (DACS) does not reclassify an area simply because there have been short-term events, like sewage spills or extraordinary rain events, that have resulted in the area's temporary closure. Where there are frequent, extended periods of closures due to high fecal coliform counts in an area that exceed Class II water quality criteria for bacteriological quality, however, one would reasonably expect that reclassification action would be taken. Even if the DACS does not take such action, the water may nonetheless qualify for placement on the "planning list" pursuant to Subsection (1) of proposed Rule 62-303.370, Florida Administrative Code, based upon the fecal coliform data relied upon by the DACS in closing the area, provided the data meets the requirements set forth in proposed Rule 62-303.320, Florida Administrative Code. The DACS has never reclassified an area from "prohibited" to "unclassified." David Heil, the head of the SEAS, made a presentation at the April 20, 2000, TAC meeting, during which he enumerated various ways that the Department could determine "impairment as it relates to shellfish harvesting waters" and recommended, over the others, one of those options: combination of the average number and duration of closures over time. None of the options listed by Mr. Heil, including his top recommendation, were incorporated in proposed Rule 62- 303.370, Florida Administrative Code. The TAC and Department staff looked into the possibility of using the option touted by Mr. Heil, but determined that it would not be practical to do so. Relying on the DACS' reclassification of harvesting areas was deemed to be a more practical approach that was "consistent with the way the Department classifies waters as Class II and therefore it was included in the proposed rule."55 Code Part II: Proposed Rule 62-303.380, Florida Administrative Proposed Rule 62-303.380, Florida Administrative Code, provides three separate ways for a water to "be placed on the planning list for drinking water use support" and, in addition, addresses "human-health based criteria" not covered elsewhere in Part II of the proposed rule chapter. It reads as follows: Drinking Water Use Support and Protection of Human Health. A Class I water shall be placed on the planning list for drinking water use support if: the water segment does not meet the applicable Class I water quality criteria based on the methodology described in section 62-303.320, or a public water system demonstrates to the Department that either: Treatment costs to meet applicable drinking water criteria have increased by at least 25% to treat contaminants that exceed Class I criteria or to treat blue-green algae or other nuisance algae in the source water, or the system has changed to an alternative supply because of additional costs that would be required to treat their surface water source. When determining increased treatment costs described in paragraph (b), costs due solely to new, more stringent drinking water requirements, inflation, or increases in costs of materials shall not be included. A water shall be placed on the planning list for assessment of the threat to human health if: for human health-based criteria expressed as maximums, the water segment does not meet the applicable criteria based on the methodology described in section 62- 303.320, or for human health-based criteria expressed as annual averages, the annual average concentration for any year of the assessment period exceeds the criteria. To be used to determine whether a water should be assessed further for human-health impacts, data must meet the requirements of paragraphs (2), (3), (6), and (7) in rule 62-303.320. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New Use of the statistical "methodology described in [proposed Rule] 62-303.320," Florida Administrative Code, is not only appropriate (as discussed above) for making "planning list" determinations based upon "[e]xceedances of [a]quatic [l]ife- [b]ased [c]riteria" and "water quality criteria for bacteriological quality," it is also a reasonable way to determine whether a water should "be placed on the planning list for drinking water use support" based upon exceedances of "applicable Class I water quality criteria" (as Subsection (1)(a) of proposed Rule 62-303.380, Florida Administrative Code, provides) and to determine whether a water should "be placed on the planning list for assessment of the threat to human health" based upon exceedances of other "human-health based criteria expressed as maximums" (as Subsection (2)(a) of the proposed Rule 62-303.380, Florida Administrative Code, provides). Subsection (1)(b) was included in proposed Rule 62- 303.380, Florida Administrative Code, because the TAC and Department staff wanted "some other way," besides having the minimum number of exceedances of "applicable Class I water quality criteria" required by Subsection (1)(a) of the proposed rule, for a Class I water to qualify for "place[ment] on the planning list for drinking water use support." Looking at the costs necessary for public water systems to treat surface water,56 as Subsection (1)(b) of proposed Rule 62-303.380, Florida Administrative Code, allows, is a reasonable alternative means of determining whether a Class I water should be "placed on the planning list for drinking water use support." Under Subsection (1)(b) of proposed Rule 62-303.380, Florida Administrative Code, the cost analysis showing that the requirements for listing have been met must be provided by the public water system. This burden was placed on the public water system because the Department "does not have the resources to do that assessment on [its] own." The Department cannot be fairly criticized for not including in Subsection (1)(b)1. of proposed Rule 62-303.380, Florida Administrative Code, references to the other contaminants (in addition to blue-green algae) that have "been put on a list by the EPA to be . . . evaluated for future regulations" inasmuch as there are no existing criteria in Chapter 62-302, Florida Administrative Code, specifically relating to these contaminants. Particularly when read together with the third sentence of Subsection (1) of proposed Rule 62-303.300 (which provides that "[i]t should be noted water quality criteria are designed to protect either aquatic life use support, which is addressed in sections 62-303.310-353, or to protect human health, which is addressed in sections 62-303.360-380"), it is clear that the "human health-based criteria" referenced in Subsection (2) of proposed Rule 62-303.380, Florida Administrative Code, are those numerical criteria in Rule Chapter 62-302, Florida Administrative Code, designed to protect human health. While laypersons not familiar with how water quality criteria are established may not be able to determine (by themselves) which of the numerical water quality criteria in Rule Chapter 62-302, Florida Administrative Code, are "human health-based," as that term is used Subsection (2) of proposed Rule 62-303.380, Florida Administrative Code, Department staff charged with the responsibility of making listing decisions will be able to so. "[H]uman health-based criteria" for non-carcinogens are "expressed as maximums" in Rule Chapter 62-302, Florida Administrative Code. "[H]uman health-based criteria" for carcinogens are "expressed as annual averages" in Rule Chapter 62-302, Florida Administrative Code. "Annual average," as that term is used in Rule Chapter 62-302, Florida Administrative Code, is defined therein as "the maximum concentration at average annual flow conditions. (see Section 62-4.020(1), F.A.C.)." Subsection (1) of Rule 62- 4.020, Florida Administrative Code, provides that "[a]verage [a]nnual [f]low "is the long-term harmonic mean flow of the receiving water, or an equivalent flow based on generally accepted scientific procedures in waters for which such a mean cannot be calculated." The "annual mean concentration" is not exactly the same as, but it does "generally approximate" and is "roughly equivalent to," the "maximum concentration at average annual flow conditions." Using "annual mean concentrations" to determine whether there have been exceedances of a "human health-based criteria expressed as annual averages" is a practical approach that makes Subsection (2)(b) of proposed Rule 62-303.380, Florida Administrative Code, more easily "implementable" inasmuch as it obviates the need to calculate the "average annual flow," which is a "fairly complicated" exercise requiring "site-specific flow data" not needed to determine the "annual mean concentration."57 Subsection (2)(b) of proposed Rule 62-303.380, Florida Administrative Code, does not impose any minimum sample size requirements, and it requires only one exceedance of any "human health-based criteri[on] expressed as [an] annual average[]" for a water to be listed. The limitations it places on the data that can be considered (by incorporating by reference the provisions of Subsections (2), (3), (6), and (7) of proposed Rule 62-303.320, Florida Administrative Code, which have been discussed above) are reasonable. Part III: Overview Part III of proposed Rule Chapter 62-303, Florida Administrative Code, contains the following provisions, which describe the "verified list" of impaired waters for which TMDLs will be calculated, how the list will be compiled, and the manner in which waters on the list will be "prioritized" for TMDL development: Proposed Rules 62-303.400, 62-303.420, 62- 303.430, 62-303.440, 62-303.450, 62-303.460, 62-303.470, 62- 303.480, 62-303.500, 62-303.600, 62-303.700, and 62-303.710, Florida Administrative Code. Code Part III: Proposed Rule 62-303.400, Florida Administrative Proposed Rule 62-303.400, Florida Administrative Code, is entitled, "Methodology to Develop the Verified List," and reads as follows: Waters shall be verified as being impaired if they meet the requirements for the planning list in Part II and the additional requirements of sections 62- 303.420-.480. A water body that fails to meet the minimum criteria for surface waters established in Rule 62-302.500, F.A.C.; any of its designated uses, as described in this part; or applicable water quality criteria, as described in this part, shall be determined to be impaired. Additional data and information collected after the development of the planning list will be considered when assessing waters on the planning list, provided it meets the requirements of this chapter. In cases where additional data are needed for waters on the planning list to meet the data sufficiency requirements for the verified list, it is the Department's goal to collect this additional data[58] as part of its watershed management approach, with the data collected during either the same cycle that the water is initially listed on the planning list (within 1 year) or during the subsequent cycle (six years). Except for data used to evaluate historical trends in chlorophyll a or TSIs, the Department shall not use data that are more than 7.5 years old at the time the water segment is proposed for listing on the verified list. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New Pursuant to the first sentence of proposed Rule 62- 303.400, Florida Administrative Code, if a water qualifies for placement on the "planning list" under a provision in Part II of the proposed rule chapter that does not have a counterpart in proposed Rules 62-303.420 through 62-303.480, Florida Administrative Code, that water will automatically be "verified as being impaired." Examples of provisions in Part II of the proposed rule chapter that do not have counterparts in proposed Rules 62-303.420 through 62-303.480, Florida Administrative Code, are: the provision in Subsection (3) of proposed Rule 62- 303.330, Florida Administrative Code, that "water segments with at least . . . one failure of the biological integrity standard, Rule 62-302.530(11), shall be included on the planning list for assessment of aquatic life use support"; Subsection (1) of proposed Rule 62-303.370, Florida Administrative Code, which provides that a water will be placed on the "planning list" if it "does not meet applicable Class II water quality criteria for bacteriological quality based upon the methodology described in section 62-303.320," Florida Administrative Code; Subsection (3) of proposed Rule 62-303.370, Florida Administrative Code, which provides that a Class II water will be placed on the "planning list" if it "includes an area that has been approved for shellfish harvesting by the Shellfish Evaluation and Assessment Program, but which has been downgraded from its initial harvesting classification to a more restrictive classification"; and Subsection (1)(b) of proposed Rule 62-303.380, Florida Administrative Code, pursuant to which a water may qualify for "planning list" placement based upon water treatment costs under the circumstances described therein. Waters that are "verified as being impaired," it should be noted, will not automatically qualify for placement on the "verified list." They will still have to be evaluated in light of the provisions (which will be discussed later in greater detail) of proposed Rule 62-303.600, Florida Administrative Code (relating to "pollution control mechanisms") and those of proposed Rules 62-303.700 and 62- 303.710, Florida Administrative Code (which require that the Department identify the "pollutant(s)" and "concentration(s)" that are "causing the impairment" before placing a water on the "verified list"). Of the "minimum criteria for surface waters established in Rule 62-302.500, F.A.C.," the only ones addressed anywhere in proposed Rules 62-303.310 through 62-303.380 and 62- 303.410 through 62-303.480, Florida Administrative Code, are the requirement that surface water not be "acutely toxic" and the requirement that predominantly marine waters not have silver in concentrations above 2.3 micrograms per liter. In determining whether there has been a failure to meet the remaining "minimum criteria," the Department will exercise its "best professional judgment." Like the second sentence of Proposed Rule 62-303.300, Florida Administrative Code, the second sentence of proposed Rule 62-303.400, Florida Administrative Code, incorporates the concept of "independent applicability" by providing that only one of the listed requirements need be met for a water to be deemed "impaired." Neither Subsection (1) of proposed Rule 62-303.400, Florida Administrative Code, nor any other provision in the proposed rule chapter, requires that a water be on the "planning list" as a prerequisite for inclusion on the "verified list." Indeed, a reading of Subsection (3)(c) of proposed Rule 62- 303.500, Florida Administration, the "prioritization" rule, which will be discussed later, leaves no reasonable doubt that, under the proposed rule chapter, a water can be placed on the "verified list" without having first been on the "planning list." The second sentence of Subsection (2) of proposed Rule 62-303.400, Florida Administrative Code, indicates when the Department hopes to be able to collect the "additional data needed for waters on the planning list to meet the [more rigorous] data sufficiency requirements for the verified list," which data the Department pledges, in subsequent provisions of Part III of the proposed rule chapter, will be collected (at some, unspecified time). The Department did not want to create a mandatory timetable for its collection of the "additional data" because it, understandably, wanted to avoid making a commitment that, due to funding shortfalls that might occur in the future, it would not be able to keep.59 If it has the funds to do so, the Department intends to collect the "additional data" within the time frame indicated in the second sentence of proposed Rule 62-303.400, Florida Administrative Code. The Department will not need to collect this "additional data" if the data is collected and presented to the Department by an "interested party" outside the Department. (The proposed rule chapter allows data collected by outside parties to be considered by the Department in making listing decisions, provided the data meets the prescribed quality requirements.) Requiring (as the third and final sentence of Subsection (2) of proposed Rule 62-303.400, Florida Administrative Code, does) that all data relied upon by the Department for placing waters on the "verified list," except for data establishing "historical trends in chlorophyll a or TSIs," under no circumstances be older than "7.5 years old at the time the water segment is proposed for listing on the verified list" is a reasonable requirement designed to avoid final listing decisions based upon outdated data not representative of the water's current conditions. As noted above, the TAC recommended that listing decisions be based upon data no older than five years old. Wanting to "capture as much data for the assessment process" as reasonably possible, Department staff determined that the appropriate maximum age of data should be two and half years older than that recommended by the TAC (the two and a half years representing the amount of time it could take to "do additional data collection" following the creation of the "planning list"). Part III: Proposed Rule 62-303.410, Florida Administrative Code Proposed Rule 62-303.410, Florida Administrative Code, is entitled, "Determination of Aquatic Life Use Support," and provides as follows: Failure to meet any of the metrics used to determine aquatic life use support listed in sections 62-303.420-.450 shall constitute verification that there is an impairment of the designated use for propagation and maintenance of a healthy, well-balanced population of fish and wildlife. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New Like proposed Rule 62-303.310, Florida Administrative Code, its analogue in Part II of the proposed rule chapter, proposed Rule 62-303.410, Florida Administrative Code, incorporates the concept of "independent applicability." A failure of any of the "metrics" referenced in the proposed rule will result in "verification" of impairment. Code Part III: Proposed Rule 62-303.420, Florida Administrative Proposed Rule 62-303.420, Florida Administrative Code, the counterpart of proposed Rule 62-303.320, Florida Administrative Code, establishes a reasonable statistical method, involving binomial distribution analysis, to verify impairment based upon "[e]xceedances of [a]quatic [l]ife-[b]ased [w]ater [q]uality [c]riteria" due to pollutant discharges. It reads as follows: Exceedances of Aquatic Life-Based Water Quality Criteria The Department shall reexamine the data used in rule 62-303.320 to determine exceedances of water quality criteria. If the exceedances are not due to pollutant discharges and reflect either physical alterations of the water body that cannot be abated or natural background conditions, the water shall not be listed on the verified list. In such cases, the Department shall note for the record why the water was not listed and provide the basis for its determination that the exceedances were not due to pollutant discharges. If the Department cannot clearly establish that the exceedances are due to natural background or physical alterations of the water body but the Department believes the exceedances are not due to pollutant discharges, it is the Department's intent to determine whether aquatic life use support is impaired through the use of bioassessment procedures referenced in section 62-303.330. The water body or segment shall not be included on the verified list for the parameter of concern if two or more independent bioassessments are conducted and no failures are reported. To be treated as independent bioassessments, they must be conducted at least two months apart. If the water was listed on the planning list and there were insufficient data from the last five years preceding the planning list assessment to meet the data distribution requirements of section 303.320(4) and to meet a minimum sample size for verification of twenty samples, additional data will be collected as needed to provide a minimum sample size of twenty. Once these additional data are collected, the Department shall re-evaluate the data using the approach outlined in rule 62- 303.320(1), but using Table 2, which provides the number of exceedances that indicate a minimum of a 10% exceedance frequency with a minimum of a 90% confidence level using a binomial distribution. The Department shall limit the analysis to data collected during the five years preceding the planning list assessment and the additional data collected pursuant to this paragraph. Table 2: Verified List Minimum number of measured exceedances needed to put a water on the Planning list with at least 90% confidence that the actual exceedance rate is greater than or equal to ten percent. Sample Are listed if they Sizes have at least this From To # of exceedances 20 25 5 26 32 6 33 40 7 41 47 8 48 55 9 56 63 10 64 71 11 72 79 12 80 88 13 89 96 14 97 104 15 105 113 16 114 121 17 122 130 18 131 138 19 139 147 20 148 156 21 157 164 22 165 173 23 174 182 24 183 191 25 192 199 26 200 208 27 209 217 28 218 226 29 227 235 30 236 244 31 245 253 32 254 262 33 263 270 34 271 279 35 280 288 36 289 297 37 298 306 38 307 315 39 316 324 40 325 333 41 334 343 42 344 352 43 353 361 44 362 370 45 371 379 46 380 388 47 389 397 48 398 406 49 407 415 50 416 424 51 425 434 52 435 443 53 444 452 54 453 461 55 462 470 56 471 479 57 480 489 58 490 498 59 499 500 60 (3) If the water was placed on the planning list based on worst case values used to represent multiple samples taken during a seven day period, the Department shall evaluate whether the worst case value should be excluded from the analysis pursuant to subsections (4) and (5). If the worst case value should not be used, the Department shall then re-evaluate the data following the methodology in rule 62-303.420(2), using the more representative worst case value or, if all valid values are below acutely toxic levels, the median value. If the water was listed on the planning list based on exceedances of water quality criteria for metals, the metals data shall be validated to determine whether the quality assurance requirements of rule 62- 303.320(7) are met and whether the sample was both collected and analyzed using clean techniques, if the use of clean techniques is appropriate. If any data cannot be validated, the Department shall re-evaluate the remaining valid data using the methodology in rule 62-303.420(2), excluding any data that cannot be validated. Values that exceed possible physical or chemical measurement constraints (pH greater than 14, for example) or that represent data transcription errors, outliers the Department determines are not valid measures of water quality, water quality criteria exceedances due solely to violations of specific effluent limitations contained in state permits authorizing discharges to surface waters, water quality criteria exceedances within permitted mixing zones for those parameters for which the mixing zones are in effect, and water quality data collected following contaminant spills, discharges due to upsets or bypasses from permitted facilities, or rainfall in excess of the 25-year, 24-hour storm, shall be excluded from the assessment. However, the Department shall note for the record that the data were excluded and explain why they were excluded. Once the additional data review is completed pursuant to paragraphs (1) through (5), the Department shall re-evaluate the data and shall include waters on the verified list that meet the criteria in rules 62-303.420(2) or 62-303.320(5)(b). Specific Authority: 403.061, 403.067, FS. Law Implemented: 403.021(11), 403.062, 403.067, FS. History -- New The TMDL program is intended to address only water quality impairment resulting from pollutant discharges (from point or non-point sources), as is made clear by a reading of Section 403.067, Florida Statutes, particularly Subsection 6(a)2. thereof (which, as noted above, provides that, "[f]or waters determined to be impaired due solely to factors other than point and nonpoint sources of pollution, no maximum daily load will be required"). Subsection (1)(a) of proposed Rule 62- 303.420(1)(a), Florida Administrative Code, is in keeping with this intent. Subsection (1)(b) of proposed Rule 62-303.420, Florida Administrative Code, should be read together with Subsection (1)(a) of the proposed rule. The "physical alterations of the water body" referred to in Subsection (1)(b) are the same type of "physical alterations" referred to in Subsection (1)(a), to wit: "physical alterations of the water body that cannot be abated." "Best professional judgment" will be used by the Department in determining, as it must under Subsection (1) of proposed Rule 62-303.420, Florida Administrative Code, whether or not exceedances are due to pollutant discharges. If the Department, exercising its "best professional judgment," finds that there is not proof "clearly establish[ing] that the exceedances are due to natural background or physical alterations of the water body but the Department believes the exceedances are not due to pollutant discharges," the Department, pursuant to Subsection (1)(b) of proposed Rule 62- 303.420, Florida Administrative Code, will determine whether the water in question should be "verified as impaired" for aquatic life use support by relying on "[b]iological [a]ssessment[s]" conducted in accordance with the procedures set forth in proposed Rule 62-303.330, Florida Administrative Code (which, among other things, prohibit reliance on "[b]iological [a]ssessment[s]" based on "data older than ten years"). The results of these "[b]iological [a]ssessment[s]" will not make the Department any better able to "answer the question of whether natural background or physical alterations were responsible for [the] exceedances," but, as noted above, it will enable the Department to make a more informed decision about the overall ability of the water to sustain aquatic life. Subsection (1)(b) of proposed Rule 62-303.420, Florida Administrative Code, reasonably provides that the water will not be "verified as impaired" for aquatic life use support if there have been two or more "[b]iological [a]ssessment[s]" conducted at least two months apart over the last ten years and "no failures [have been] reported." That a water has "passe[d]" these "[b]iological [a]ssessment[s]" establishes "that aquatic life use support is being maintained" and, under such circumstances, it would be inappropriate to include that water on the "verified list." Looking at just the data "from the last five years preceding the planning list assessment," as the first sentence of Subsection (2) of proposed Rule 62-303.420, Florida Administrative Code, requires the Department to do, rather than all of the data supporting the placement of the water in question on the "planning list," regardless of when the data was collected, makes sense because, to properly discharge its responsibilities under Section 403.067, Florida Statutes, the Department must ascertain what the current overall condition of the water in question is. As noted above, Subsection (2) of proposed Rule 62- 303.420, Florida Administrative Code, requires a "minimum sample size for verification [of impairment based upon "[e]xceedances of [a]quatic [l]ife-[b]ased [w]ater [q]uality [c]riteria]" of twenty samples," with no exceptions. While this is more than the number of samples required for "planning list" compilation purposes under proposed Rule 62-303.320, Florida Administrative Code, it "is a very small number of samples relative to the [number of] samples that [the Department] would need to take to do a TMDL." Furthermore, unlike any provision in proposed Rule 62-303.320, Florida Administrative Code, Subsection (2) of proposed Rule 62-303.420, Florida Administrative Code, provides that, if a water (on the "planning list") lacks the required minimum number of samples, the "additional data" needed to meet the minimum sample requirement "will be collected" (at some unspecified time in the future). Because these additional samples "will be collected," the requirement of proposed Rule 62-303.420, Florida Administrative Code, that there be a minimum of 20 samples should not prevent deserving waters from ultimately being "verified as impaired" under the proposed rule (although it may serve to delay such "verification"). Such delay would occur if a water on the "planning list" had five or more exceedances within the "last five years preceding the planning list assessment" (five being the minimum number of exceedances required for "verification" under proposed Rule 62- 303.420, Florida Administrative Code), but these exceedances were based on fewer than 20 samples. The additional samples that would need to be collected to meet the minimum sample size requirement of Subsection (2) of proposed Rule 62-303.420, Florida Administrative Code, would have no effect on the Department's "verification" determination, even if these samples yielded no exceedances, given that proposed Rule 62-303.420, Florida Administrative Code, does not contain any provision comparable to Subsection (3) of Rule 62-303.320, Florida Administrative Code, providing that, under certain circumstances, "more recent data" may render "older data" unusable.60 The water would qualify for "verification" regardless of what the additional samples revealed. That is not to say, however, that taking these additional samples would serve no useful purpose. Data derived from these additional collection efforts (shedding light on the severity of the water quality problem) could be used by the Department to help it "establish priority rankings and schedules by which water bodies or segments will be subjected to total maximum daily load calculations," as the Department is required to do pursuant to Subsection (4) of Section 403.067, Florida Statutes. The "calculations [reflected in the table, Table 2, which is a part of Subsection (2) of proposed Rule 62-303.420, Florida Administrative Code] are correct." They are based on "a minimum of a 10% exceedance frequency with a minimum of a 90% confidence level using a binomial distribution." As noted above, the Department did not act unreasonably in selecting this "exceedance frequency" and "confidence level" for use in determining which waters should be "verified as impaired" based upon "[e]xceedances of [a]quatic [l]ife-[b]ased [w]ater [q]uality [c]riteria." Subsection (4) of proposed Rule 62-303.420, Florida Administrative Code, imposes reasonable quality assurance requirements that must be met in order for "metals data" to be considered "valid" for purposes of determining whether a water has the minimum number of exceedances needed to be "verified as impaired" under the proposed rule. It requires that "Method 1669"-permitted procedures be used only where these procedures are "appropriate." Determining the appropriateness of these procedures in a particular case will require the Department to exercise its "best professional judgment," taking into consideration the amount of the metal in question needed to violate the applicable water quality criterion, in relation to the amount of contamination that could be expected to occur during sample collection and analysis if conventional techniques were used. Doing so should result in "Method 1669"-permitted procedures being deemed "appropriate" in only a few circumstances: when a water is being tested to determine if it exceeds the applicable criterion for mercury, and when testing low hardness waters61 for exceedances of the applicable criterion for cadmium and lead. It is necessary to use "Method 1669"-permitted procedures in these instances to prevent test results that are tainted by contamination occurring during sample collection and analysis. Subsection (5) of proposed Rule 62-303.420, Florida Administrative Code, reasonably excludes other data from the "verification" process. It contains the same exclusions that pursuant to Subsection (6) of proposed Rule 62-303.320, Florida Administrative Code, apply in determining whether a water should be placed on the "planning list" based upon "[e]xceedances of [a]quatic [l]ife-[b]ased [w]ater [q]uality [c]riteria" ("[v]alues that exceed possible physical or chemical measurement constraints (pH greater than 14, for example) or that represent data transcription errors, [and] outliers the Department determines are not valid measures of water quality"), plus additional exclusions. Among the additional types of data that will be excluded from consideration under Subsection (5) of proposed Rule 62-303.420, Florida Administrative Code, are "exceedances due solely to violations of specific effluent limitations contained in state permits authorizing discharges to surface waters." Permit violations, by themselves, can cause water quality impairment; however, as the Department has reasonably determined, the quickest and most efficient way to deal with such impairment is to take enforcement action against the offending permittee. To take the time and to expend the funds to develop and implement a TMDL62 to address the problem, instead of taking enforcement action, would not only be unwise and an imprudent use of the not unlimited resources available to combat poor surface water quality in this state, but would also be inconsistent with the expression of legislative intent in Subsection (4) of Section 403.067, Florida Statutes, that the TMDL program not be utilized to bring a water into compliance with water quality standards where "technology-based effluent limitations [or] other pollution control programs under local, state, or federal authority" are sufficient to achieve this result. It is true that the Department has not stopped, through enforcement, all permit violations and that, as Mr. Joyner acknowledged during his testimony at the final hearing, "there are certain cases out there where there are chronic violations of permits." The appropriate response to this situation, however, is for the Department to step up its enforcement efforts, not for it to develop and implement TMDLs for those waters that, but for these violations, would not be impaired. (Citizens dissatisfied with the Department's enforcement efforts can themselves take action, pursuant to Section 403.412(2), Florida Statutes, to seek to enjoin permit violations.) It will be "extremely difficult" to know whether exceedances are due solely to permit violations. Because of this, it does not appear likely that the Department "will be using [the permit violation exclusion contained in] proposed [R]ule [62-303.420(5), Florida Administrative Code] very often." Subsection (5) of proposed Rule 62-303.420, Florida Administrative Code, will not exclude from consideration all water quality criteria exceedances in mixing zones . Only those exceedances relating to the parameters "for which the mixing zones are in effect" will be excluded. The exclusion of these exceedances is appropriate inasmuch as, pursuant to the Department's existing rules establishing the state's water quality standards (which the Legislature made clear, in Subsections (9) and (10) of Section 403.067, Florida Statutes, it did not, by enacting Section 403.067, intend to alter or limit), these exceedances are permitted and not considered to be violations of water quality standards. To the extent that there may exist "administratively- continued" permits (that is, permits that remain in effect while a renewal application is pending, regardless of their expiration date) which provide for outdated "mixing zones," this problem should be addressed through the permitting process, not the TMDL program. A "contaminant spill," as that term is used in Subsection (5) of proposed Rule 62-303.420, Florida Administrative Code, is a short-term, unpermitted discharge [of contaminants63] to surface waters." (See Subsection (16) of proposed Rule 62-303.200, Florida Administrative Code, recited above, which defines "spill," as it is used in the proposed rule chapter). It is well within the bounds of reason to exclude from consideration (as Subsection (5) of proposed Rule 62- 303.420, Florida Statutes, indicates the Department will do in deciding whether a water should be "verified as being impaired" under the proposed rule) data collected in such proximity in time to a "contaminant spill" that it reflects only the temporary effects of that "short-term" event (which are best addressed by the Department taking immediate action), rather than reflecting a chronic water quality problem of the type the TMDL program is designed to help remedy. In deciding whether this exclusion applies in a particular case, the Department will need to exercise its "best professional judgment" to determine whether the post-"contaminant spill" data reflects a "short- term" water quality problem attributable to the "spill" (in which case the exclusion will apply) or whether, instead, it reflects a chronic problem (in which case the exclusion will not apply). "Bypass" is defined in Subsection (4) of Rule 62- 620.200, Florida Administrative Code, as "the intentional diversion of waste streams from any portion of a treatment works." "Upset" is defined in Subsection (50) of Rule 62- 620.200, Florida Administrative Code, as follows: "Upset" means an exceptional incident in which there is unintentional and temporary noncompliance with technology-based effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, careless or improper operation. An upset constitutes an affirmative defense to an action brought for noncompliance with technology based permit effluent limitations if the requirements of upset provisions of Rule 62-620.610, F.A.C., are met. The "upset provisions of Rule 62-620.610, F.A.C." are as follows: (23) Upset Provisions. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: An upset occurred and that the permittee can identify the cause(s) of the upset; The permitted facility was at the time being properly operated; The permittee submitted notice of the upset as required in condition (20) of this permit; and The permittee complied with any remedial measures required under condition (5) of this permit. In any enforcement proceeding, the permittee seeking to establish the occurrence of an upset has the burden of proof. Before an enforcement proceeding is instituted, no representation made during the Department review of a claim that noncompliance was caused by an upset is final agency action subject to judicial review. Rule 62-620.610, Florida Administrative Code, also contains "[b]ypass [p]rovisions," which provide as follows: (22) Bypass Provisions. Bypass is prohibited, and the Department may take enforcement action against a permittee for bypass, unless the permittee affirmatively demonstrates that: Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; and There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated waste, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and The permittee submitted notices as required under condition (22)(b) of this permit. If the permittee knows in advance of the need for a bypass, it shall submit prior notice to the Department, if possible at least 10 days before the date of the bypass. The permittee shall submit notice of an unanticipated bypass within 24 hours of learning about the bypass as required in condition (20) of this permit. A notice shall include a description of the bypass and its cause; the period of the bypass, including exact dates and times; if the bypass has not been corrected, the anticipated time it is expected to continue; and the steps taken or planned to reduce, eliminate, and prevent recurrence of the bypass. The Department shall approve an anticipated bypass, after considering its adverse effect, if the permittee demonstrates that it will meet the three conditions listed in condition (22)(a)1. through 3. of this permit. A permittee may allow any bypass to occur which does not cause reclaimed water or effluent limitations to be exceeded if it is for essential maintenance to assure efficient operation. These bypasses are not subject to the provision of condition (22)(a) through (c) of this permit. The "bypasses" to which the Department refers in Subsection (5) of proposed Rule 62-303.420, Florida Administrative Code, are those that are not prohibited (as Mr. Joyner testified and is evidenced by the grouping of "bypasses" in the same provision with "upsets" and by the fact that there is another provision in Subsection (5) of the proposed rule that deals with permit violations). Since these types of bypasses, as well as upsets, are exceptional events that, under the Department's existing rules, are allowed to occur without the permittee being guilty of a permit violation, it is reasonable, in verifying impairment under proposed Rule 62-303.420, Florida Administrative Code, to discount data tainted by their occurrence, which reflect atypical conditions resulting from legally permissible discharges. The "25-year, 24-hour storm" exclusion was included in Subsection (5) of proposed Rule 62-303.420, Florida Administrative Code, in response to the TAC's recommendation that the proposed rule "exclude data from extreme storm events." The "25-year, 24-hour storm" is "commonly used in the regulatory context as a dividing line between extremely large rainfall events and less extreme events." It is a rainfall event (or as one witness, the chief of the Department's Bureau of Watershed Management, Eric Livingston, put it, a "gully washer") that produces an amount of rainfall within 24 hours that is likely to be exceeded on the average only once in 25 years. In Florida, that amount is anywhere from about eight to 11 inches, depending on location. Because a "25-year, 24-hour storm" is an extraordinary rainfall event that creates abnormal conditions in affected waters, there is reasonable justification for the Department's not considering, in the "verification" process under proposed Rule 62-303.420, Florida Administrative Code, "25-year, 24-hour storm"-impacted data. This should result in the exclusion of very little data. Data collected following less severe rainfall events (of which there are many in Florida)64 will be unaffected by the "25- year, 24-hour storm" exclusion in Subsection (5) of proposed Rule 62-303.420, Florida Administrative Code. Code Part III: Proposed Rule 62-303.430, Florida Administrative Proposed Rule 62-303.430, Florida Administrative Code, the counterpart of proposed Rule 62-303.330, Florida Administrative Code, establishes a reasonable non-statistical approach, involving "[b]iological [a]ssessment," to be used as an alternative to the statistical method described in proposed Rule 62-303.420, Florida Administrative Code, in verifying aquatic life use support impairment. Proposed Rule 62-303.430, Florida Administrative Code, reads as follows: Biological Impairment All bioassessments used to list a water on the verified list shall be conducted in accordance with Chapter 62-160, F.A.C., including Department-approved Standard Operating Procedures. To be used for placing waters on the verified list, any bioassessments conducted before the adoption of applicable SOPs for such bioassessments as part of Chapter 62-160 shall substantially comply with the subsequent SOPs. If the water was listed on the planning list based on bioassessment results, the water shall be determined to be biologically impaired if there were two or more failed bioassessments within the five years preceding the planning list assessment. If there were less than two failed bioassessments during the last five years preceding the planning list assessment the Department will conduct an additional bioassessment. If the previous failed bioassessment was a BioRecon, then an SCI will be conducted. Failure of this additional bioassessment shall constitute verification that the water is biologically impaired. If the water was listed on the planning list based on other information specified in rule 62-303.330(4) indicating biological impairment, the Department will conduct a bioassessment in the water segment, conducted in accordance with the methodology in rule 62-303.330, to verify whether the water is impaired. For streams, the bioassessment shall be an SCI. Failure of this bioassessment shall constitute verification that the water is biologically impaired. Following verification that a water is biologically impaired, a water shall be included on the verified list for biological impairment if: There are water quality data reasonably demonstrating the particular pollutant(s) causing the impairment and the concentration of the pollutant(s); and One of the following demonstrations is made: if there is a numeric criterion for the specified pollutant(s) in Chapter 62-302, F.A.C., but the criterion is met, an identification of the specific factors that reasonably demonstrate why the numeric criterion is not adequate to protect water quality and how the specific pollutant is causing the impairment, or if there is not a numeric criterion for the specified pollutant(s) in Chapter 62- 302, F.A.C., an identification of the specific factors that reasonably demonstrate how the particular pollutants are associated with the observed biological effect. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New Subsection (1) of proposed Rule 62-303.430, Florida Administrative Code, was written in anticipation of the "adoption of applicable SOPs" for BioRecons, SCIs, and LCIs "as part of [Rule] Chapter 62-160," Florida Administrative Code, subsequent to the adoption of the proposed rule chapter. As noted above, at the time of the final hearing in these cases, the Department was in the process of engaging in rulemaking to incorporate in Rule Chapter 62-160, Florida Administrative Code, the SOPs for BioRecons, SCIs, and LCIs that Department personnel currently use to conduct these "[b]iological [a]ssessment[s]." Until the rulemaking process is completed and any amendments to Rule Chapter 62-160, Florida Administrative Code, become effective,65 to be "used to list a water on the verified list" pursuant to Subsection (1) of proposed Rule 62-303.430, Florida Administrative Code, "[b]iological [a]assessment[s]" need meet only the quality assurance requirements of the pre-amendment version of Rule Chapter 62-160 (which does not include SOPs for BioRecons, SCIs and LCIs). Once the amendments become effective, however, "[b]iological [a]assessment[s]," both pre- and post-amendment, will have to have been conducted in substantial compliance with the applicable SOPs included in the new version of Rule Chapter 62-160. No "[b]iological [a]assessment" will be rejected under Subsection (1) of proposed Rule 62-303.430, Florida Administrative Code, because it fails to comply with an SOP that, at the time of the "verification" determination, has not been made a part of the Department's rules. The TAC-approved requirement of Subsection (2) of proposed Rule 62-303.430, Florida Administrative Code, that there be at least "two failed bioassessments during the last five years preceding the planning list assessment" (as opposed to a longer period of time) in order for a water to be "verified as being [biologically] impaired," without the need to conduct another "[b]iological [a]assessment," is reasonably designed to avoid listing decisions that are based upon test results not representative of the existing overall biological condition of the water in question. Two such failed "[b]iological [a]assessment[s]" will provide the Department with a greater degree of assurance that the water truly suffers from "biological impairment" than it would have if only one failed "[b]iological [a]assessment" was required. If there are fewer than "two failed bioassessments during the last five years preceding the planning list assessment," Subsection (2) of proposed Rule 62-303.430, Florida Administrative Code, provides that the Department will conduct another "[b]iological [a]ssessment" to determine whether the water should be "verified as being [biologically] impaired," and failure of this additional "[b]iological [a]assessment" will constitute "verification that the water is biologically impaired." The requirement that there be another failed "[b]iological [a]assessment" to confirm "biological impairment" before a water is "verified as being [biologically] impaired" under Subsection (2) of proposed Rule 62-303.430, Florida Administrative Code, is scientifically prudent, particularly in those cases where the water was placed on the "planning list" based upon a "[b]iological [a]ssessment" conducted more than five years earlier. The failure of this additional "[b]iological [a]ssessment" is enough to get the water "verified as being [biologically] impaired" even if there were no failed "[b]iological [a]ssessment[s]" in the "last five years preceding the planning list assessment." Inasmuch as the SCI, compared to the BioRecon, is a more comprehensive and rigorous test, it is reasonable to require (as Subsection (2) of proposed Rule 62-303.430, Florida Administrative Code, does) that, in the case of a stream placed on the "planning list" as a result of a failed BioRecon, the additional "[b]iological [a]ssessment" be an SCI, not a BioRecon, and to also require (as Subsection (3) of proposed Rule 62-303.430, Florida Administrative Code, does) that an SCI, rather than a BioRecon, be conducted where a stream has been placed on the "planning list" based upon "other information specified in rule 62-303.330(4) indicating biological impairment." Until such time as the Department develops a rapid bioassessment protocol for estuaries, where the Department is required in Part II of the proposed rule chapter to conduct an additional "[b]iological [a]ssessment, the Department intends to meet this obligation by engaging in "biological integrity standard" testing. TMDLs are pollutant-specific. If a water is "verified as [biologically] impaired," but the Department is not able to identify a particular pollutant as the cause of the impairment, a TMDL cannot be developed. See Section 403.031(21), Florida Statutes (to establish TMDL it is necessary to calculate the "maximum amount of a pollutant that a water body or water segment can assimilate from all sources without exceeding water quality standards"); and Section 403.067(6)(a)2., Florida Statutes ("The total maximum daily load calculation shall establish the amount of a pollutant that a water body or water body segment may receive from all sources without exceeding water quality standards"). Accordingly, as noted above, in Subsection (3)(c) of Section 403.067, Florida Statutes, the Legislature has imposed the following perquisites to the Department listing, on its "updated list" of waters for which TMDLs will be calculated, those waters deemed to be impaired based upon "non-attainment [of] biological criteria": If the department has adopted a rule establishing a numerical criterion for a particular pollutant, a narrative or biological criterion may not be the basis for determining an impairment in connection with that pollutant unless the department identifies specific factors as to why the numerical criterion is not adequate to protect water quality. If water quality non-attainment is based on narrative or biological criteria, the specific factors concerning particular pollutants shall be identified prior to a total maximum daily load being developed for those criteria for that surface water or surface water segment. Furthermore, Subsection (4) of Section 403.067, Florida Statutes, provides that, if a water is to placed on the "updated list" on any grounds, the Department "must specify the particular pollutants causing the impairment and the concentration of those pollutants causing the impairment relative to the water quality standard." The requirements of Subsection (4) of proposed Rule 62-303.430, Florida Administrative Code, are consistent with these statutory mandates. Proposed Rule 62-303.430, Florida Statutes, does not address waters placed on the "planning list" based upon a failure of the "biological integrity standard" set forth in Subsection (11) of Rule 62-302.530, Florida Administrative Code. Therefore, by operation of proposed Rule 62-303.400, Florida Administrative Code, waters meeting the minimum requirements for "planning list" placement based upon failure of the "biological integrity standard" (a single failure within the ten-year period preceding the "planning list" assessment) will automatically be "verified as being impaired." This is a less stringent "verification" requirement than the Department adopted in proposed Rule 62-303.430, Florida Administrative Code, for "verification" of waters placed on the "planning list" based upon a failed BioRecon, SCI, or LCI. While the results of BioRecons, SCIs, and LCIs are more accurate indicators of "biological impairment" than are the results of "biological integrity standard" testing, the Department's decision to make it more difficult for a water to be "verified as being impaired" if it was placed on the "planning list" based upon a failed BioRecon, SCI, or LCI (as opposed to a failure of the "biological integrity standard") is reasonably justified inasmuch as the "biological integrity standard" is one of the water quality criteria that have been established by the Department in Rule 62-302.530, Florida Administrative Code, whereas, in contrast, neither the BioRecon, SCI, nor LCI are a part of the state's water quality standards. Code Part III: Proposed Rule 62-303.440, Florida Administrative Proposed Rule 62-303.440, Florida Administrative Code, the counterpart of proposed Rule 62-303.340, Florida Administrative Code, prescribes another reasonable method, that is not statistically-based, to verify aquatic life use support impairment. It reads as follows: : Toxicity A water segment shall be verified as impaired due to surface water toxicity in the receiving water body if: the water segment was listed on the planning list based on acute toxicity data, or the water segment was listed on the planning list based on chronic toxicity data and the impairment is confirmed with a failed bioassessment that was conducted within six months of a failed chronic toxicity test. For streams, the bioassessment shall be an SCI. Following verification that a water is impaired due to toxicity, a water shall be included on the verified list if the requirements of paragraph 62-303 430(4) are met. Toxicity data collected following contaminant spills, discharges due to upsets or bypasses from permitted facilities, or rainfall in excess of the 25-year, 24-hour storm, shall be excluded from the assessment. However, the Department shall note for the record that the data were excluded and explain why they were excluded. Specific Authority 403.061, 403.067, FS. Law Implemented 403. 062, 403.067, FS. History -- New Pursuant to Subsections (1)(a) and (3) of proposed Rule 62-303.440, Florida Administrative Code, a water will automatically be "verified as impaired" for aquatic life use support if it was placed on the "planning list" on the basis of being "acutely toxic," provided that the data supporting such placement was "not collected following contaminant spills, discharges due to upsets or bypasses from permitted facilities, or rainfall in excess of the 25-year, 24-hour storm." The TAC and Department staff determined that additional testing was not necessary for "verification" under such circumstances because the end point that characterizes "acute toxicity" is so "dramatic" in terms of demonstrating impairment that it would be best to "just go ahead and put [the water] on the list with the two acute [toxicity] failures and start figuring out any potential sources of that impairment." The TAC and Department staff, however, reasonably believed that, because "chronic toxicity tests, in contrast, are measuring fairly subtle changes in a lab test organism" and there is "a very long history within the NPDES program of people questioning the results of the chronic toxicity test," before a water is "verified as being impaired" due to "chronic toxicity," the impairment should be "confirmed with a bioassessment that was conducted within six months of a failed chronic toxicity test"66 (as Subsection (1)(b) of proposed Rule 62-303.440, Florida Administrative Code, provides). It is reasonable to require that the bioassessment, in the case of a stream, be an SCI, rather than a BioRecon, because, as noted above, of the two, the former is the more comprehensive and rigorous test. The requirements of Subsection (2) of proposed Rule 62-303.440, Florida Administrative Code, are consistent with the provisions of the Subsections (3)(c) and (4) of Section 403.067, Florida Statutes. It may be difficult to identify the pollutant causing the impairment inasmuch as toxicity tests are not designed to yield such information. The rationale for excluding, in the assessment process described in proposed Rule 62-303.440, Florida Administrative Code, "data collected following contaminant spills, discharges due to upsets or bypasses from permitted facilities, or rainfall in excess of the 25-year, 24-hour storm" (as Subsection (3) of the proposed rule does) is the same, justifiable rationale (discussed above) supporting the exclusion of such data in the assessment of impairment under proposed Rule 62-303.420, Florida Administrative Code. Code Part III: Proposed Rule 62-303.450, Florida Administrative Proposed Rule 62-303.450, Florida Administrative Code, the counterpart of proposed Rules 62-303.350 through 62- 303.353, Florida Administrative Code, provides other reasonable ways, not based upon statistics, for waters to be "verified as [being] impaired" for aquatic life use support. It reads as follows: Interpretation of Narrative Nutrient Criteria. A water shall be placed on the verified list for impairment due to nutrients if there are sufficient data from the last five years preceding the planning list assessment combined with historical data (if needed to establish historical chlorophyll a levels or historical TSIs), to meet the data sufficiency requirements of rule 62- 303.350(2). If there are insufficient data, additional data shall be collected as needed to meet the requirements. Once these additional data are collected, the Department shall re-evaluate the data using the thresholds provided in rule 62-303.351- .353, for streams, lakes, and estuaries, respectively, or alternative, site-specific thresholds that more accurately reflect conditions beyond which an imbalance in flora or fauna occurs in the water segment. In any case, the Department shall limit its analysis to the use of data collected during the five years preceding the planning list assessment and the additional data collected in the second phase. If alternative thresholds are used for the analysis, the Department shall provide the thresholds for the record and document how the alternative threshold better represents conditions beyond which an imbalance in flora or fauna is expected to occur. If the water was listed on the planning list for nutrient enrichment based on other information indicating an imbalance in flora or fauna as provided in Rule 62-303 350(1), the Department shall verify the imbalance before placing the water on the verified list for impairment due to nutrients and shall provide documentation supporting the imbalance in flora or fauna. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New The requirement of the first sentence of Subsection (1) of proposed Rule 62-303.450, Florida Administrative Code, that there be sufficient (non-historical) data (as measured against the requirements of Subsection (2) of proposed Rule 62- 303.350, Florida Administrative Code67) "from [just] the last five years preceding the planning list assessment" in order for a "nutrient impair[ed]" water to go directly from the "planning list" to the "verified list" (subject to the provisions of proposed Rules 62-303.600, 62-303.700, and 62-303.710, Florida Administrative Code) is reasonably designed to avoid listing decisions based upon outdated data not representative of the water's current conditions. According to the second and third sentences of Subsection (1) of proposed Rule 62-303.450, Florida Administrative Code, if there is not enough data from this five- year time period, the additional data needed to meet the data sufficiency requirements "will be collected" by the Department, and such additional data, along with the data "from the last five years preceding the planning list assessment," will be evaluated to determine whether one of the applicable thresholds set out in proposed Rules 62-303.351 through 62-303.353, Florida Administrative Code, or an "alternative" threshold established specifically for that water, has been met or exceeded. Deciding whether "alternative, site-specific thresholds" should be used and, if so, what they should be, will involve the exercise of the Department's "best professional judgment," as will the determination as to how, in each case the Department is presented with a water placed on the "planning list for nutrient enrichment based on other information indicating an imbalance in flora or fauna," it should go about "verify[ing] the imbalance," as the Department will be required to do by Subsection (2) of proposed Rule 62-303.450, Florida Administrative Code. In some instances, the Department will only need to thoroughly review the "other information" to "verify the imbalance." In other cases, where the "other information" is not sufficiently detailed, new "information" will need to be obtained. How the Department will proceed in a particular case will depend upon the specific circumstances of that case. Code Part III: Proposed Rule 62-303.460, Florida Administrative Proposed Rule 62-303.460, Florida Administrative Code, the counterpart of proposed Rule 62-303.360, Florida Administrative Code, establishes a reasonable means to determine whether waters should be "verified as [being] impaired" for primary contact and recreation use support. It reads as follows: Primary Contact and Recreation Use Support The Department shall review the data used by the DoH as the basis for bathing area closures, advisories or warnings and verify that the values exceeded the applicable DoH thresholds and the data meet the requirements of Chapter 62-160. If the segment is listed on the planning list based on bathing area closures, advisories, or warnings issued by a local health department or county government, closures, advisories, or warnings based on red tides, rip tides, sewer line breaks, sharks, medical wastes, hurricanes, or other factors not related to chronic discharges of pollutants shall not be included when verifying primary contact and recreation use support. The Department shall then re-evaluate the remaining data using the methodology in rule 62- 303.360(1)(c). Water segments that meet the criteria in rule 62-303.360(1)(c) shall be included on the verified list. If the water segment was listed on the planning list due to exceedances of water quality criteria for bacteriological quality, the Department shall, to the extent practical, evaluate the source of bacteriological contamination and shall verify that the impairment is due to chronic discharges of human-induced bacteriological pollutants before listing the water segment on the verified list. The Department shall take into account the proximity of municipal stormwater outfalls, septic tanks, and domestic wastewater facilities when evaluating potential sources of bacteriological pollutants. For water segments that contain municipal stormwater outfalls, the impairment documented for the segment shall be presumed to be due, at least in part, to chronic discharges of bacteriological pollutants. The Department shall then re-evaluate the data using the methodology in rule 62-303.320(1), excluding any values that are elevated solely due to wildlife. Water segments shall be included on the verified list if they meet the requirements in rule 62-303.420(6). Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New The first sentence of Subsection (1) of proposed Rule 62-303.460, Florida Administrative Code, was included in the proposed rule in response to comments made by stakeholders during the rule development process that the Department would be "abdicating [its] authority" if, in determining whether a water was impaired for purposes of TMDL development, it relied solely on action taken by other governmental entities. Department staff agreed that the Department, "as the agency responsible for preparing this list," should at least "review the data used by the DoH as the basis for bathing area closures, advisories or warnings and verify that the values exceeded the applicable DoH thresholds and the data meet the requirements of Chapter 62- 160," Florida Administrative Code. The rationale for the Department not considering bathing area "closures, advisories, or warnings based on red tides, rip tides, sewer line breaks, sharks, medical wastes, hurricanes, or other factors not related to chronic discharges of pollutants . . . when verifying [impairment of] primary contact and recreation use support" (per the second sentence of Subsection (1) of proposed Rule 62-303.460, Florida Administrative Code) is the same, justifiable rationale (discussed above) supporting the exclusions of these closures, advisories, and warnings from consideration in the determination of whether a water should be placed on the "planning list" pursuant to Subsections (1)(b), (1)(c), or (1)(d) of the proposed Rule 62-303.360, Florida Administrative Code. The exclusions set forth in the second sentence of Subsection (1) of proposed Rule 62-303.460, Florida Administrative Code, will have no effect on the "information" or "data" that the Department will be able to consider under any provision in Part III of the proposed rule chapter other than Subsection (1) of proposed Rule 62-303.460. Pursuant to the third and fourth sentences of Subsection (1) of proposed Rule 62-303.460, Florida Administrative Code, after the Department determines, in accordance with the first and second sentences of this subsection of the proposed rule, what bacteriological data-based bathing area closures, advisories, and warnings should be counted, it will determine whether there were a total of at least 21 days of such closures, advisories, and warnings during a calendar year (the number required by Subsection (1)(c) of proposed Rule 62-303.360, Florida Administrative Code, for placement on the "planning list") and, if there were, it will verify the water in question as being impaired for primary contact and recreation use support. This is the only way for a water to be "verified as being impaired" based upon bathing area closures, advisories, or warnings under the proposed rule chapter. The "criteria" set forth in Subsections (1)(b) and (1)(d) of proposed Rule 62-303.360, Florida Administrative Code (unlike the criteria set forth in Subsection (1)(c) of proposed Rule 62-303.360) are not carried forward in proposed Rule 62- 303.460, Florida Administrative Code. Subsection (2) of proposed Rule 62-303.460, Florida Administrative Code, provides another way, based upon a statistical analysis of "exceedances of water quality criteria for bacteriological quality," for a water to be "verified as being impaired" for primary contact and recreation use support. It reasonably requires the Department, in determining whether such impairment exists, to use the same valid statistical methodology (discussed above) that it will use, pursuant to proposed Rule 62-303.420, Florida Administrative Code, to determine whether a water should be "verified as being impaired" based upon "[e]xceedances of [a]quatic [l]ife-[b]ased [c]riteria." Under Subsection (2) of proposed Rule 62-303.460, Florida Administrative Code, the Department, to the extent practical, will evaluate the source of an exceedance to make sure that it is "due to chronic discharges of human-induced bacteriological pollutants," and, if such evaluation reveals that the exceedance was "solely due to wildlife," the exceedance will be excluded from the calculation. While it is true that "microbial pollutants from [wildlife] do constitute a public health risk in recreational waters," the purpose of the TMDL program is to control human-induced impairment and, consequently, the Department is not required to develop TMDLs "[f]or waters determined to be impaired due solely to factors other than point and nonpoint sources of pollution." See Section 403.067(6)(a)2., Florida Statutes. Part III: Proposed Rule 62-303.470, Florida Administrative Code Rule 62-303.470, Florida Administrative Code, the counterpart of proposed Rule 62-303.370, Florida Administrative Code, establishes a reasonable means to determine whether waters should be "verified as being impaired" for fish and shellfish consumption use support. It provides as follows: Fish and Shellfish Consumption Use Support In order to be used under this part, the Department shall review the data used by the DoH as the basis for fish consumption advisories and determine whether it meets the following requirements: the advisory is based on the statistical evaluation of fish tissue data from at least twelve fish collected from the specific water segment or water body to be listed, starting one year from the effective date of this rule the data are collected in accordance with DEP SOP FS6000 (General Biological Tissue Sampling) and FS 6200 (Finfish Tissue Sampling), which are incorporated by reference, the sampling entity has established Data Quality Objectives (DQOs) for the sampling, and the data meet the DQOs. Data collected before one year from the effective date of this rule shall substantially comply with the listed SOPs and any subsequently developed DQOs. there are sufficient data from within the last 7.5 years to support the continuation of the advisory. If the segment is listed on the planning list based on fish consumption advisories, waters with fish consumption advisories for pollutants that are no longer legally allowed to be used or discharged shall not be placed on the verified list because the TMDL will be zero for the pollutant. Waters determined to meet the requirements of this section shall be listed on the verified list. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New Proposed Rule 62-303.470, Florida Administrative Code, imposes additional requirements only for those waters placed on the "planning list" based upon fish consumption advisories pursuant to Subsection (2) of proposed Rule 62- 303.370, Florida Administrative Code. Waters placed on the "planning list" pursuant to Subsections (1) and (3) of proposed Rule 62-303.370, Florida Administrative Code, are not addressed in the proposed rule (or anywhere else in Part III of the proposed rule chapter). Accordingly, as noted above, these waters will go directly from the "planning list" to the "verified list" (subject to the provisions of proposed Rules 62- 303.600, 62-303.700, and 62-303.710, Florida Administrative Code). The mere fact that a fish consumption advisory is in effect for a water will be enough for that water to qualify for placement on the "planning list" under Subsection (2) of proposed Rule 62-303.370, Florida Administrative Code. The Department will not look beyond the four corners of the advisory at this stage of the "identification of impaired surface waters" process. Proposed Rule 62-303.470, Florida Administrative Code, however, will require the Department, before including the water on the "verified list" based upon the advisory, to conduct such an inquiry and determine the adequacy of the fish tissue data supporting the initial issuance of the advisory and its continuation. Mandating that the Department engage in such an exercise as a prerequisite to verifying impairment based upon a fish consumption advisory is a provident measure in keeping with the Legislature's directive that the TMDL program be "scientifically based." Department staff's intent, in requiring (in Subsection (1)(a) of proposed Rule 62-303.470, Florida Administrative Code) that there be fish tissue data from at least 12 fish, "was to maintain the status quo" and not require any more fish tissue samples than the Department of Health presently uses to determine whether an advisory should be issued. The SOPs incorporated by reference in Subsection (1)(b) of proposed Rule 62-303.470, Florida Administrative Code, contain quality assurance requirements that are essentially the same as those that have been used "for many years" to collect the fish tissue samples upon which fish consumption advisories are based. These SOPs have yet to be incorporated in Rule Chapter 62-160, Florida Administrative Code. Data Quality Objectives are needed for sampling to be scientifically valid. There are presently no Data Quality Objectives in place for the sampling that is done in connection with the Department of Health's fish consumption advisory program. Pursuant to Subsection (1)(b) of proposed Rule 62- 303.470, Florida Administrative Code, after one year from the effective date of the proposed rule, in order for data to be considered in determining data sufficiency questions under the proposed rule, the sampling entity will have to have established Data Quality Objectives for the collection of such data and the data will have to meet, or (in the case of "data collected before one year from the effective date of this rule") substantially comply with, these Data Quality Objectives. As noted above, the majority of fish consumption advisories now in effect were issued based upon fish tissue data collected more than 7.5 years ago that has not been supplemented with updated data. It "will be a huge effort to collect additional data that's less than seven-and-a-half years old" for the waters under these advisories (and on the "planning list" as a result thereof) to determine, in accordance with Subsection (1)(c) of proposed Rule 62-303.470, Florida Administrative Code, whether the continuation of these advisories is warranted. Undertaking this "huge effort," instead of relying on data more than 7.5 years old to make these determinations, is reasonably justified because this 7.5-plus-year-old data that has already been collected may no longer be representative of the current conditions of the waters in question and it therefore is prudent to rely on more recent data. Subsection (1)(c) of proposed Rule 62-303.470, Florida Administrative Code, does not specify the amount of fish tissue data that will be needed in order for the Department to determine that there is sufficient data to "support the continuation of the advisory." The Department will need to exercise its "best professional judgment" on a case-by-case basis in making such sufficiency determinations. Part III: Proposed Rule 62-303.480, Florida Administrative Code Proposed Rule 62-303.480, Florida Administrative Code, the counterpart of proposed Rule 62-303.380, Florida Administrative Code, establishes a reasonable means to determine whether waters should be "verified as being impaired" for the protection of human health. It provides as follows: Drinking Water Use Support and Protection of Human Health If the water segment was listed on the planning list due to exceedances of a human health-based water quality criterion and there were insufficient data from the last five years preceding the planning list assessment to meet the data sufficiency requirements of section 303.320(4), additional data will be collected as needed to meet the requirements. Once these additional data are collected, the Department shall re-evaluate the data using the methodology in rule 62-303.380(2) and limit the analysis to data collected during the five years preceding the planning list assessment and the additional data collected pursuant to this paragraph (not to include data older than 7.5 years). For this analysis, the Department shall exclude any data meeting the requirements of paragraph 303.420(5). The following water segments shall be listed on the verified list: for human health-based criteria expressed as maximums, water segments that meet the requirements in rule 62-303.420(6), or for human health-based criteria expressed as annual averages, water segments that have an annual average that exceeds the applicable criterion. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New Proposed Rule 62-303.480, Florida Administrative Code, imposes additional requirements only for those waters placed on the "planning list" for "assessment of the threat to human health" pursuant to Subsection (2) of proposed Rule 62- 303.380, Florida Administrative Code. Notwithstanding that proposed Rule 62-303.480, Florida Administrative Code, is entitled, "Drinking Water Use Support and Protection of Human Health," waters placed on the "planning list" for drinking water use support pursuant to Subsection (1) of proposed Rule 62- 303.380, Florida Administrative Code, are not addressed in the proposed rule (or anywhere else in Part III of the proposed rule chapter). Accordingly, as noted above, these waters will go directly from the "planning list" to the "verified list" (subject to the provisions of proposed Rules 62-303.600, 62- 303.700, and 62-303.710, Florida Administrative Code). Proposed Rule 62-303.480, Florida Administrative Code, reasonably requires the Department, in determining whether a water should be "verified as being impaired" for the protection of human health based upon exceedances of "human health-based criteria expressed as maximums," to use the same valid statistical methodology (discussed above) that it will use, pursuant to proposed Rule 62-303.420, Florida Administrative Code, to determine whether a water should be "verified as being impaired" based upon "[e]xceedances of [a]quatic [l]ife-[b]ased [c]riteria." Proposed Rule 62-303.480, Florida Administrative Code, also sets forth an appropriate method for use in determining whether a water should be "verified as being impaired" based upon exceedances of "human health-based criteria expressed as annual averages." Only one exceedance of any "human health-based criteria expressed as an annual average" will be needed for a water to be listed under the proposed rule, the same number needed under Subsection (2)(b) of proposed Rule 62-303.380, Florida Administrative Code, for a water to make the "planning list." Under proposed Rule 62-303.480, Florida Administrative Code, however, unlike under Subsection (2)(b) of proposed Rule 62-303.380, Florida Administrative Code, the data relied upon by the Department will have to meet the "data sufficiency requirements of section [62]-303.320(4)," Florida Administrative Code, and, in addition, data of the type described in Subsection (5) of proposed Rule 62-303.420, Florida Administrative Code, as well as data collected more than "five years preceding the planning list assessment," will be excluded from the Department's consideration. Code Part III: Proposed Rule 62-303.500, Florida Administrative As noted above, Subsection (4) of Section 403.067, Florida Statutes, directs the Department, "[i]n association with [its preparation of an] updated list [of waters for which TMDLs will be calculated, to] establish priority rankings and schedules by which water bodies or segments will be subjected to total maximum daily load calculations." Proposed Rule 62- 303.500, Florida Administrative Code, explains how the Department will go about carrying out this statutory directive. It reads as follows: When establishing the TMDL development schedule for water segments on the verified list of impaired waters, the Department shall prioritize impaired water segments according to the severity of the impairment and the designated uses of the segment taking into account the most serious water quality problems; most valuable and threatened resources; and risk to human health and aquatic life. Impaired waters shall be prioritized as high, medium, or low priority. The following waters shall be designated high priority: Water segments where the impairment poses a threat to potable water supplies or to human health. Water segments where the impairment is due to a pollutant regulated by the CWA and the pollutant has contributed to the decline or extirpation of a federally listed threatened or endangered species, as indicated in the Federal Register listing the species. The following waters shall be designated low priority: [W]ater segments that are listed before 2010 due to fish consumption advisories for mercury (due to the current insufficient understanding of mercury cycling in the environment). Man-made canals, urban drainage ditches, and other artificial water segments that are listed only due to exceedances of the dissolved oxygen criteria. Water segments that were not on a planning list of impaired waters, but which were identified as impaired during the second phase of the watershed management approach and were included in the verified list, unless the segment meets the criteria in paragraph (2) for high priority. All segments not designated high or low priority shall be medium priority and shall be prioritized based on the following factors: the presence of Outstanding Florida Waters. the presence of water segments that fail to meet more than one designated use. the presence of water segments that exceed an applicable water quality criterion or alternative threshold with a greater than twenty-five percent exceedance frequency with a minimum of a 90 percent confidence level. the presence of water segments that exceed more than one applicable water quality criteria. administrative needs of the TMDL program, including meeting a TMDL development schedule agreed to with EPA, basin priorities related to following the Department's watershed management approach, and the number of administratively continued permits in the basin. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New It is anticipated that most waters on the Department's "updated list" will fall within the "medium priority" category. Subsections (4)(a) through (4)(e) of proposed Rule 62-303.500, Florida Administrative Code, describe those factors (including, among others, the "presence of Outstanding Florida Waters" and "the number of administratively continued permits in the basin," the latter being added "based on input from the Petitioners") that will be taken into account by the Department in prioritizing waters within this "medium priority" category; but nowhere in the proposed rule does the Department specify how much weight each factor will be given relative to the other factors. This is a matter that, in accordance with the TAC's recommendation, will be left to the "best professional judgment" of the Department. "[T]here is a lot known about mercury" and its harmful effects; however, as the Department correctly suggests in Subsection (3)(a) of proposed Rule 62-303.500, Florida Administrative Code, there is not yet a complete understanding of "mercury cycling in the environment" and how mercury works its way up the food chain. "[T]here are a series of projects that are either on the drawing board or in progress now" that, hopefully, upon their conclusion, will give the Department a better and more complete understanding of what the sources of mercury in Florida surface waters are and how mercury "cycles" in the environment and ends up in fish tissue. Until the Department has such an understanding, though, it is reasonable for waters "verified as being impaired" due to fish consumption advisories for mercury to be given a "low priority" designation for purposes of TMDL development (as the Department, in Subsection (3)(a) of proposed Rule 62-303.500, Florida Administrative Code, indicates it will). Code Part III: Proposed Rule 62-303.600, Florida Administrative As noted above, proposed Rule 62-303.600, Florida Administrative Code, like Subsection (5) of proposed Rule 62- 303.100, Florida Administrative Code, is designed to give effect to and make more specific the language in Subsection (4) of Section 403.067, Florida Statutes, that an impaired water may be listed on the Department's "updated list" of waters for which TMDLs will be calculated only "if technology-based effluent limitations and other pollution control programs under local, state, or federal authority, including Everglades restoration activities pursuant to s. 373.4592 and the National Estuary Program, which are designed to restore such waters for the pollutant of concern are not sufficient to result in attainment of applicable surface water quality standards." It reads as follows: Evaluation of Pollution Control Mechanisms Upon determining that a water body is impaired, the Department shall evaluate whether existing or proposed technology- based effluent limitations and other pollution control programs under local, state, or federal authority are sufficient to result in the attainment of applicable water quality standards. If, as a result of the factors set forth in (1), the water segment is expected to attain water quality standards in the future and is expected to make reasonable progress towards attainment of water quality standards by the time the next 303(d) list is scheduled to be submitted to EPA,[68] the segment shall not be listed on the verified list. The Department shall document the basis for its decision, noting any proposed pollution control mechanisms and expected improvements in water quality that provide reasonable assurance that the water segment will attain applicable water quality standards. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New It is beyond reasonable debate that, pursuant to Subsection (4) of Section 403.067, Florida Statutes, before the Department may include impaired waters on the "updated list" of waters for TMDLs will be calculated, it must evaluate whether "technology-based effluent limitations and other pollution control programs" are sufficient for water quality standards in these waters to be attained in the future. (To construe the statute as requiring the Department to simply look back, and not forward into the future, in conducting its mandated evaluation of "pollution control programs" would render meaningless the language in the statute directing the Department to conduct such an evaluation after having determined that these waters are impaired.69 As Mr. Joyner testified at the final hearing in explaining what led Department staff "to conclude that [the Department] should be considering future achievement of water quality standards or future implementation of such [pollution control] programs": [I]t [Subsection (4) of Section 403.067, Florida Statutes] basically requires two findings. It's impaired and these things won't fix the problem. If the "won't fix the problem" required it to be fixed right now in the present tense [to avoid listing], then it couldn't be impaired. So it would just be an illogical construction of having two requirements in the statute.) Proposed Rule 62-303.600, Florida Administrative Code, does not specify when "in the future" water quality attainment resulting from an existing or proposed "pollution control program" must be expected to occur in order for a presently impaired water to not be listed; but neither does Subsection (4) of Section 403.067, Florida Statutes, provide such specificity. Indeed, the statute's silence on the matter was the very reason that Department staff did "not set a time frame for [expected] compliance with water quality standards." Rather than "set[ting] such a time frame," Department staff took other measures "to address the open nature of the statute" and limit the discretion the Legislature granted the Department to exclude presently impaired waters from the "updated list" based upon there being pollution control programs sufficient to result in these waters attaining water quality standards in the future "for the pollutant of concern." They included language in Subsection (5) of proposed Rule 62-303.100, Florida Administrative Code, and in proposed Rule 62-303.600, Florida Administrative Code, requiring that the Department, before exercising such discretion to exclude a presently impaired water from the "updated list," have "reasonable assurance" that water quality standards will be attained and that "reasonable progress" will be made in attaining these standards within a specified time frame, to wit: "by the time the next 303(d) list is scheduled to be submitted to EPA." "Reasonable assurance" is a term that has a "long history" of use by the Department in various programs,70 including its wastewater permitting program.71 Neither sheer speculation that a pollution control program will result in future water quality attainment, nor mere promises to that effect, will be sufficient, under Subsection of proposed Rule 62-303.100, Florida Administrative Code, and proposed Rule 62-303.600, Florida Administrative Code, to exclude an impaired water from the "updated list." The Department will need to examine and analyze the specific characteristics of each impaired water, as well as the particular pollution control program in question, including its record of success and/or failure, if any, before determining (through the use of its "best professional judgment") whether there is the "reasonable assurance" required by these proposed rule provisions. How much time it will take for an impaired water to attain water quality standards will depend on various water- specific factors, including the size of the water body, the size of the watershed, and whether there are pollutants stored in the sediment. The particular circumstances of each case, therefore, will dictate what constitutes "reasonable progress72 towards attainment of water quality standards by the time the next 303(d) list is scheduled to be submitted to EPA," within the meaning of Subsection (5) of proposed Rule 62-303.100, Florida Administrative Code, and proposed Rule 62-303.600, Florida Administrative Code. Because of the case-specific factors involved in determining "reasonable assurance" and "reasonable progress," it was not practicable for Department staff to specify in Subsection (5) of proposed Rule 62-303.100, Florida Administrative Code, and in proposed Rule 62-303.600, Florida Administrative Code, exactly what would be needed to be shown in each case to establish "reasonable assurance" and "reasonable progress." At the April 26, 2001, rule adoption hearing, Department staff proposed an amendment to proposed Rule 62- 303.600, Florida Administrative, to make the proposed rule more specific by adding "a list of elements that needed to be addressed to provide reasonable assurance" and defining "reasonable progress." The amendment, which was opposed by the DACS and regulated interests, was withdrawn before being considered by the ERC because Department staff felt that is was not "quite well thought out enough," particularly insofar as it addressed the concept of "reasonable progress." Part III: Proposed Rule 62-303.700, Florida Administrative Code As noted above, proposed Rule 62-303.700, Florida Administrative Code, describes the first two phases of the "basin management cycle" and the TMDL-related events that will occur during these phases. It reads as follows: Listing Cycle The Department shall, to the extent practical, develop basin-specific verified lists of impaired waters as part of its watershed management approach, which rotates through the State's surface water basins on a five year cycle. At the end of the first phase of the cycle, which is designed to develop a preliminary assessment of the basin, the Department shall update the planning list for the basin and shall include the planning list in the status report for the basin, which will be noticed to interested parties in the basin. If the specific pollutant causing the impairment in a particular water segment is not known at the time the planning list is prepared, the list shall provide the basis for including the water segment on the planning list. In these cases, the pollutant and concentration causing the impairment shall be identified before the water segment is included on the verified list to be adopted by Secretarial Order. During the second phase of the cycle, which is designed to collect additional data on waters in the basin, interested parties shall be provided the opportunity to work with the Department to collect additional water quality data. Alternatively, interested parties may develop proposed water pollution control mechanisms that may affect the final verified list adopted by the Secretary at the end of the second phase. To ensure that data or information will be considered in the preliminary basin assessment, it must be submitted to the Department or entered into STORET or, if applicable, the DoH database no later than September 30 during the year of the assessment. Within a year of the effective date of this rule, the Department shall also prepare a planning list for the entire state. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New The preference expressed in proposed Rule 62-300.700, Florida Administrative Code, for verified lists to be developed on a "basin-specific" basis "as part of the Department's watershed management approach" is consistent with the directive in the first sentence of Subsection (3)(a) of Section 403.067, Florida Statutes, that the Department conduct its TMDL assessment for the “basin in which the water body . . . is located.” Proposed Rule 62-300.700, Florida Administrative Code, carries out the mandate in the second sentence of Subsection (3)(a) of Section 403.067, Florida Statutes, that, in conducting its TMDL assessment, the Department "coordinate" with "interested parties." Furthermore, the proposed rule makes clear that parties outside the Department will have the opportunity "work with the Department to collect additional water quality data" needed to meet data sufficiency requirements. Identifying the "pollutant and concentration causing the impairment" before including a water on the "verified list," as proposed Rule 62-303.700, Florida Administrative Code, requires be done, is something the Department will need to do to comply with the directive contained in the third sentence of Subsection (4) of Section 403.067, Florida Statutes. Part III: Proposed Rule 62-303.710, Florida Administrative Code Proposed Rule 62-303.710, Florida Administrative Code, addresses the "[f]ormat of [v]erified [l]ist and [v]erified [l]ist [a]pproval." It reads as follows: The Department shall follow the methodology established in this chapter to develop basin-specific verified lists of impaired water segments. The verified list shall specify the pollutant or pollutants causing the impairment and the concentration of the pollutant(s) causing the impairment. If the water segment is listed based on water quality criteria exceedances, then the verified list shall provide the applicable criteria. However, if the listing is based on narrative or biological criteria, or impairment of other designated uses, and the water quality criteria are met, the list shall specify the concentration of the pollutant relative to the water quality criteria and explain why the numerical criterion is not adequate. For waters with exceedances of the dissolved oxygen criteria, the Department shall identify the pollutants causing or contributing to the exceedances and list both the pollutant and dissolved oxygen on the verified list. For waters impaired by nutrients, the Department shall identify whether nitrogen or phosphorus, or both, are the limiting nutrients, and specify the limiting nutrient(s) in the verified list. The verified list shall also include the priority and the schedule for TMDL development established for the water segment, as required by federal regulations. The verified list shall also note any waters that are being removed from the current planning list and any previous verified list for the basin. The verified basin-specific 303(d) list shall be approved by order of the Secretary. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New The second and fourth sentences of Subsection (1) of proposed Rule 62-303.710, Florida Administrative Code, track the requirements of the third sentence of Subsection (4) and the first and second sentences of Subsection (3)(c), respectively, of Section 403.067, Florida Statutes. Furthermore, as a practical matter, a TMDL cannot be developed if the culprit pollutant is not able to be identified. Subsection (2) of proposed Rule 62-303.710, Florida Administrative Code, was included in the proposed rule because, in most instances, the Department does not consider dissolved oxygen to be a pollutant. The pollutants most frequently associated with exceedances of the dissolved oxygen criteria are nutrients (nitrogen and/or phosphorous). It is essential to identify the "limiting nutrient," as Subsection (3) of proposed Rule 62-303.710, Florida Administrative Code, requires the Department to do, inasmuch as the "limiting nutrient" is the particular pollutant for which a TMDL will be developed. Part IV: Overview Part IV of proposed Rule Chapter 62-303, Florida Administrative Code, is entitled, "Miscellaneous Provisions." It includes two proposed rules, proposed Rule 62-303.720, Florida Administrative Code, and proposed Rule 62-303.810, Florida Administrative Code. Part IV: Proposed Rule 62-303.720, Florida Administrative Code Proposed Rule 62-303.720, Florida Administrative Code, describes how waters may be removed from the "planning list" and the "verified list." The proposed rule, which is entitled, "Delisting Procedures," cites Sections 403.061 and 403.067, Florida Statutes, as its "[s]pecific [a]uthority" and Sections 403.062 and 403.067, Florida Statutes, as the "[l]aw [i]mplemented" by the proposed rule. Subsection (1) of proposed Rule 62-303.720, Florida Administrative Code, addresses the removal of waters from the "planning list." It reads as follows: Waters on planning lists developed under this Chapter that are verified to not be impaired during development of the verified list shall be removed from the State's planning list. Once a water segment is verified to not be impaired pursuant to Part III of this chapter, the data used to place the water on the planning list shall not be the sole basis for listing that water segment on future planning lists. The "removal" provisions of Subsection (1) of proposed Rule 62-303.720, Florida Administrative Code, will apply to all waters on the planning list "that are verified to not be impaired during development of the verified list," including those waters that had been placed on the "planning list" pursuant to Subsection (2) of proposed Rule 62-303.300, Florida Administrative Code, by virtue of their having been on the state's 1998 303(d) list. Waters removed from the "planning list" pursuant to Subsection (1) of proposed Rule 62-303.720, Florida Administrative Code, will be eligible to reappear on "future planning lists," but not based exclusively on "the data used to [initially] place the water on the planning list." Additional data will be needed. Subsections (2) and (3) of proposed Rule 62-303.720, Florida Administrative Code, address the removal of waters from the "verified list." They read as follows: Water segments shall be removed from the State's verified list only after completion of a TMDL for all pollutants causing impairment of the segment or upon demonstration that the water meets the water quality standard that was previously established as not being met. For waters listed due to failure to meet aquatic life use support based on water quality criteria exceedances or due to threats to human health based on exceedances of single sample water quality criteria, the water shall be delisted when: the number of exceedances of an applicable water quality criterion due to pollutant discharges is less than or equal to the number listed in Table 3 for the given sample size, with a minimum sample size of 30. This table provides the number of exceedances that indicate a maximum of a 10% exceedance frequency with a minimum of a 90% confidence level using a binomial distribution, or following implementation of pollution control activities that are expected to be sufficient to result in attainment of applicable water quality standards, evaluation of new data indicates the water no longer meets the criteria for listing established in section 62-303.420, or following demonstration that the water was inappropriately listed due to flaws in the original analysis, evaluation of available data indicates the water does not meet the criteria for listing established in section 62-303.420. New data evaluated under rule 62- 303.720(2)(a)1. must meet the following requirements: they must include samples collected during similar conditions (same seasons and general flow conditions) that the data previously used to determine impairment were collected with no more than 50% of the samples collected in any one quarter, the sample size must be a minimum of 30 samples, and the data must meet the requirements of paragraphs 62-303.320(4), (6) and (7). For waters listed due to failure to meet aquatic life use support based on biology data, the water shall be delisted when the segment passes two independent follow-up bioassessments and there have been no failed bioassessments for at least one year. The follow-up tests must meet the following requirements: For streams, the new data may be two BioRecons or any combination of BioRecons and SCIs. The bioassessments must be conducted during similar conditions (same seasons and general flow conditions) under which the previous bioassessments used to determine impairment were collected. The data must meet the requirements of Section 62-303.330(1) and (2), F.A.C. For waters listed due to failure to meet aquatic life use support based on toxicity data, the water shall be delisted when the segment passes two independent follow-up toxicity tests and there have been no failed toxicity tests for at least one year. The follow-up tests must meet the following requirements: The tests must be conducted using the same test protocols and during similar conditions (same seasons and general flow conditions) under which the previous test used to determine impairment were collected. The data must meet the requirements of rules 62-303.340(1), and the time requirements of rules 62-303.340(2) or (3). For waters listed due to fish consumption advisories, the water shall be delisted following the lifting of the advisory or when data complying with rule 62-303.470(1)(a) and (b) demonstrate that the continuation of the advisory is no longer appropriate. For waters listed due to changes in shellfish bed management classification, the water shall be delisted upon reclassification of the shellfish harvesting area to its original or higher harvesting classification. Reclassification of a water from prohibited to unclassified does not constitute a higher classification. For waters listed due to bathing area closure or advisory data, the water shall be delisted if the bathing area does not meet the listing thresholds in rule 62-303.360(1) for five consecutive years. For waters listed based on impacts to potable water supplies, the water shall be delisted when applicable water quality criteria are met as defined in rule 62- 303.380(1)(a) and when the causes resulting in higher treatment costs have been ameliorated. For waters listed based on exceedance of a human health-based annual average criterion, the water shall be delisted when the annual average concentration is less than the criterion for three consecutive years. For waters listed based on nutrient impairment, the water shall be delisted if it does not meet the listing thresholds in rule 62-303.450 for three consecutive years. For any listed water, the water shall be delisted if following a change in approved analytical procedures, criteria, or water quality standards, evaluation of available data indicates the water no longer meets the applicable criteria for listing.

Subsection (2)(a)1. of proposed rule 62-303.720, Florida Administrative Code, establishes a statistical methodology appropriate for "delisting" waters that have been listed as impaired based upon {e]xceedances of [a]quatic [l]ife- [b]ased [w]ater [q]uality [c]riteria." This "delisting" methodology" is the "equivalent" (as that term is used in Subsection (5) of Section 403.067, Florida Statutes) of the statistical methodology that will be used, pursuant to proposed Rule 62-303.420, Florida Administrative Code, to verify impairment based upon such exceedances. Both methodologies are based on the binomial model and use an "exceedance frequency" threshold of ten percent with a minimum confidence level of 90 percent. A greater minimum sample size is required under Subsection (2)(a)1. of proposed Rule 62-303.720, Florida Administrative Code, because the Department will need, thereunder, "to have at least 90 percent confidence that the actual exceedance rate is less than ten percent" "as opposed to greater than ten percent, which is a bigger range." The "calculations [reflected in the table, Table 3, which is a part of Subsection (2)(a)1. of proposed Rule 62- 303.720, Florida Administrative Code] are correct." There is nothing unreasonable about the "delisting" criteria set forth in Subsections (2)(c) and (2)(j) of proposed Rule 62-303.720, Florida Administrative Code. Subsection (2)(c) of proposed Rule 62-303.720, Florida Administrative Code, reasonably requires the Department, where waters have been "listed due to failure to meet aquatic life use support based on toxicity data" (in the form of two failed toxicity tests conducted "two weeks apart over a twelve month period"), to "delist" these waters if the Department has more recent "equivalent [toxicity] data" (in the form of two passed "follow-up toxicity tests," with no failed tests for at least twelve months) showing that the waters are not toxic. Subsection (2)(j) of proposed Rule 62-303.720, Florida Administrative Code, reasonably requires the Department to "delist" a water "following a change in approved analytical procedures" only where the change calls into question the validity and accuracy of the data that was relied upon to make the original listing determination and there is other data demonstrating that the water meets water quality standards. Code Part IV: Proposed Rule 62-303.810, Florida Administrative Proposed Rule 62-303.810, Florida Administrative Code, is entitled, "Impairment of Interstate and Tribal Waters." It reads as follows: The Department shall work with Alabama, Georgia, and federally recognized Indian Tribes in Florida to share information about their assessment methodology and share water quality data for waters that form state boundaries or flow into Florida. In cases where assessments are different for the same water body, the Department shall, to the extent practical, work with the appropriate state, Indian Tribe and EPA to determine why the assessments were different.

JOHN HIGGINS, MAUREEN HIGGINS, LOUIS MITCHELL, BETTY MITCHELL, WILLIAM SPENCE, JUNE SPENCE, ROBERT WERNER, AND LEE WERNER vs MISTY CREEK COUNTRY CLUB, INC., AND SOUTHWEST FLORIDA WATER MANAGEMENT DISTRICT, 95-002196 (1995)
Division of Administrative Hearings, Florida Filed:Sarasota, Florida May 05, 1995 Number: 95-002196 Latest Update: Dec. 05, 1995

The Issue The issue in this case is whether the Southwest Florida Water Management District (the District) should grant the application of the Misty Creek Country Club, Inc. (the Club), to modify MSSW Permit No. 400037.

Findings Of Fact Background Petitioners are owners of property adjacent to Lake No. 7 of the Misty Creek Country Club in a development called The Preserves at Misty Creek-- specifically, lot 113 (Robert and Lee Werner), lot 114 (Charles and Rosemary Biondolillo), lots 115 and 115A (Ignatius and Judith Bertola), lots 117 and 117A (Don and Halina Bogdanske), lots 118 and 118A (Louis and Betty Mitchell), lots 119 and 119A (George and Dorothy Holly), lots 120 and 120A (John and Maureen Higgins), and lot 121 (William and June Spence). Respondent, the Misty Creek Country Club (the Club), operates a golf course and country club located at The Preserves at Misty Creek under a 99-year lease with Gator Creek Lands, the developer of The Preserves at Misty Creek. Existing System Design and Application for Permit Modification In 1985, Respondent Southwest Florida Water Management District, issued a surface water management permit for development of a 730-acre residential development and golf course. The District subsequently issued to the Club operation phase authorization for the surface water management system associated with the golf course portion of the development in March of 1992. Under the original permit, Lake No. 7 was part of the overall stormwater management system for the golf course. The lake is approximately seven and half to eight acres in size and is part of a total drainage basin of approximately twenty-eight acres. As originally designed, Lake No. 7 is a detention with filtration system. An underdrain in the side of the bank provides water quality treatment, filtering out oils and greases, fertilizers and other contaminants. A control elevation of 31.02 was established for Lake No. 7 through construction of a weir. Between elevation 31.00 and 31.02, water discharges through the underdrain system providing water quality treatment. Above elevation 31.02, water flows over the control structure into Lake No. 6, and ultimately discharges to Cow Pen Slough, which is Class III waters of the state. The Club presently has a water use permit from the District which allows withdrawal of groundwater for irrigation of the golf course. Groundwater is stored in Lake No. 7 prior to use for irrigation when needed to augment water in the lake. Special Condition Number 2 of the water use permit required the Club to investigate the feasibility of using reclaimed or reuse water in lieu of groundwater for irrigation purposes at the golf course. As a result of the investigation required by Special Condition Number 2 of the water use permit, the Club filed an application with the District to modify its surface water management permit to allow for the introduction of reuse water into Lake No. 7. Under that application, there would have been no significant modifications to the stormwater management system. Reuse water would have replaced groundwater as a source for augmenting water in the lake when needed for irrigation. An eight-inch service line would convey the reuse water to Lake 7, and a float valve would control the introduction of reuse water into Lake No. 7. When water levels in the lake fell below elevation 30.5', the float valve would open the effluent line to allow introduction of reuse water into the lake; when the water elevation in the lake reached 31.0', the float valve would shut off the flow of water. There would be gate valves on either side of the structure that could be manually closed, if necessary, to stop the flow of reuse water into the lake if the float valve malfunctioned. Club personnel would have access to the gate valves and could manually stop the flow of reuse water into the lake if necessary. On August 9, 1995, just days prior to the final hearing in this matter, the Club proposed to modify its application to make certain structural changes in the design of the surface water management system. Specifically, the Club proposed to plug the window in the weir, raise the elevation of the weir or control structure to elevation 33.6, raise the elevation of the berm along the north end of Lake No. 7 adjacent to the weir to elevation 33.6, and plug the underdrain. The purpose of the proposed modifications to the design of the system was to assure that no discharge from Lake No. 7 would occur up to and including the 100-year storm event. A 100-year storm event is equal to 10 inches of rainfall in a 24-hour period. Source and Quality of Reuse Water The Club also entered into an agreement with Sarasota County to accept reuse water from the county's new Bee Ridge wastewater treatment facility. That agreement specifies the terms under which the Club will accept reuse water from the County. The County's Bee Ridge facility is presently under construction and is not yet operating. As permitted by the Department of Environmental Protection, the Bee Ridge wastewater treatment facility will use a Bardenpho waste treatment system which is a licensed process to provide advanced waste treatment. The construction permit establishes effluent limits for the facility that are comparable to a level of treatment known as advanced secondary treatment, but the County Commission for Sarasota County has instructed the County staff to operate the Bee Ridge facility as an advanced waste treatment plant. Advanced waste treatment is defined by the quality of the effluent produced. For advanced waste treatment, the effluent may not exceed 5 milligrams/Liter of biochemical oxygen demand (BOD) or total suspended solids (TSS), 3 milligrams/Liter of total nitrogen, or 1 milligram/Liter of total phosphorus. It also requires high level disinfection. Advanced secondary treatment requires the same level of treatment for TSS but the limit for nitrates is 10 milligrams/Liter. High level disinfection is also required for advanced secondary treatment. In Florida, reuse systems require a minimum of advanced secondary treatment. High level disinfection is the level of treatment that generally is accepted as being a reasonable level of treatment. The Bee Ridge permit issued to Sarasota County identifies the Club as one of the recipients of reuse water for irrigation. Condition Number 21 of that permit provides that the use of golf course ponds to store reuse water is not authorized under the County's permit until issuance of a separate permit or modification of the County's permit. Although the District did not require Misty Creek to submit any information about the modification of the County's permit, there was no basis for assuming that the County permit could not be modified. To the contrary, the permit provides that authorization may be obtained by permit modification. Under the late modification to the Club's application, the reuse water transmission line and float valve system, with backup manual gate valve system, is unchanged. So are the water elevations at which the float valve system will automatically introduce reuse water into Lake 7 and shut off. Sarasota County already has constructed the water transmission system that would deliver reuse water to the Club. At the request of the District, the Club provided copies of the drawings of the float valve structure as permitted by the Department of Environmental Protection. The District did not require certified drawings of that structure. But the District will require the Club to provide as-built drawings following completion of construction prior to the introduction of reuse water into Lake No. 7. Property Ownership Each of the Petitioners owns a residential lot adjacent to Lake No. 7. At the time of the Petitioners' purchase of the individual residential lots, the Club leased certain property immediately west of Lake No. 7 from the developer of The Preserve at Misty Creek. The leased premises included a piece of land extending into the lake known as the 19th green. As a result of negotiations between the Club and the developer, it was determined that the 19th green would be removed and the land between the approximate top of bank of Lake No. 7 and the private residential lots would be released from the Club's lease. The developer subsequently conveyed the property that had been released from the Club's lease to the individual lot owners (the "A" parcels listed in Finding 1). At the time of the conveyance of the additional parcels, the attorney for the developer prepared deeds for each individual parcel with a metes and bounds description off the rear of the residential lots to which they were being added. While the Club's application for modification of its surface water management permit was being processed by the District, counsel for Petitioners provided the District with copies of the individual deeds and questioned whether the Club had ownership or control of the land which was the subject of the application sufficient to meet the District's permitting requirements. In response to a request for information regarding the ownership of the property that was the subject of the application, the Club submitted to the District a topographical survey prepared by Mr. Steven Burkholder, a registered professional land surveyor with AM Engineering. The topographical survey depicted: the elevation of the water in the Lake No. 7 on the day that the survey was conducted, labeled "approximate water's edge"; the elevation of the "top of bank"; and the easternmost line of private ownership by Petitioners. Mr. Burkholder determined the line of private property ownership by reproducing a boundary survey attached to the individual deeds conveying the additional parcels to the Petitioners. He testified that he was confident that the topographical survey he prepared accurately represented the most easterly boundary of the Petitioners' ownership. The elevation of the line of private ownership as depicted on the survey prepared by Mr. Burkholder ranges from a low of approximately 34.5 to 35.2. The elevation of the line labeled "top of bank" ranges from a high of 35.6 to a low of 34.4. The elevation of the water in Lake No. 7 would be controlled by the elevation of the modified control structure which is proposed to be set at elevation 33.6. After modification of the surface water management system to retain the 100-year storm event, at no time would water levels in the lake rise above the existing elevation of the "top of bank." The Petitioners testified that they believed that they owned to the water's edge or edge of the lake, but Mr. Burkholder testified that a property boundary could not be determined based on an elevation depicting the water's edge because that line would change as the level of the water rose and fell. The Petitioners also presented evidence that the developer's attorney made representations to them that their ownership extended to the "approximate high water line." But there appears to be no such thing as an "approximate high water line" in surveying terms. Where the boundary of a lake is depicted on a survey it generally is depicted from top of bank to top of bank. In any event, the legal descriptions of the parcels conveyed to the Petitioners were not based on a reference to either a water line or the water's edge or the lake at all. Instead, the legal descriptions were based solely on a metes and bounds description off the rear of the residential lots. Notwithstanding some contrary evidence, if the Petitioners owned to the water's edge, such ownership would require the Petitioners to consent to or join in the amended application for the modification of the Club's surface water management permit. Information regarding the ownership or control and the legal availability of the receiving water system is required as part of the contents of an application under Rule 40D-4.101(2)(d)6. and 7., Florida Administrative Code. The amended application requires the ability to "spread" Lake 7 in the direction of the Petitioners' property. If the Petitioners own the property on which the Club intends to "spread" Lake 7 in order to make the amended application work, the Petitioners must consent or join. The issue of the legal ownership and control of the Petitioners and the Club currently is in litigation in state circuit court. If the state circuit court determines that the easterly boundary of the "A" parcels lies to the east of the "top of bank," consideration would have to be given to modifying any permit issued to the Club to insure that the designed "spread" of Lake 7 in a storm event up to and including a 100-year storm event does not encroach on the Petitioners' property. District Permit Requirements The District has never before processed an application for a surface water management permit allowing commingling of storm water and reuse water. The District applied Chapter 40D-4, Florida Administrative Code, in reviewing the Club's permit application. There are no specific provisions in Rule 40D-4 or the District's Basis of Review for Surface Water Management Permit Applications that address the commingling of stormwater and reuse water; on the other hand, no rules of the District prohibit the introduction of other types of water into a stormwater treatment pond so long as the requirements of Rule 40D-4 are met. The District has the authority to allow stormwater and reuse water to be commingled. Section 40D-4.301, Florida Administrative Code, contains the conditions for issuance of a surface water management permit. Permitting Criteria In order to obtain a surface water management permit to commingle stormwater and reuse water in Lake 7, the Club must provide reasonable assurances that the proposed modifications to its existing system will provide adequate flood control and drainage; not cause adverse water quality and quantity impacts on receiving waters and adjacent lands; not result in a violation of surface water quality standards; not cause adverse impacts on surface and groundwater levels and flows; not diminish the capability of the lake to fluctuate through the full range established for it in Chapter 40D-8, Florida Administrative Code; not cause adverse environmental impacts to wetlands, fish and wildlife or other natural resources; be effectively operated and maintained; not adversely affect public health and safety; be consistent with other public agency's requirements; not otherwise be harmful to water resources of the District; and not be against public policy. No surface or groundwater levels or flows have been set for this area of the District, so that permit criterion is not applicable to the Club's application. The Club's application will not impact wetlands or fish and wildlife associated with wetlands as described in F.A.C. Rule 40D-4.301(1)(f). There are no wetlands regulated by the District in the project site. The Club has submitted to the District an operation and maintenance plan for the modified surface water management system. The operation and maintenance plan is in compliance with the District's permitting criteria contained in Rule 40D-4.301(1)(g). The District's regulation with respect to the requirement that a project not adversely affect the public health and safety is based on the specific requirements of Chapter 40D-4, Florida Administrative Code, and the Club has complied with this criterion. The permitting criterion that a project must be consistent with the requirements of other public agencies was met by inclusion in the permit of Special Conditions Nos. 5 and 6, Limiting Condition No. 3 and Standard Condition No. 3, which require that the surface water management permit be modified if necessary to comply with modifications imposed by other public agencies. The District's regulation with respect to the requirement that a project not otherwise be harmful to the water resources within the District is based on the specific requirements of Chapter 40D-4, Florida Administrative Code, and the Club has complied with this criterion. The District's regulation with respect to the requirement that a project may not be against public policy is based on the specific requirements of Chapter 40D-4, Florida Administrative Code, and the Club has complied with that criterion. The project will not have an adverse impact on water quality or quantity in receiving waters or adjacent lands. Under the District's regulations, the project would not be permittable if it caused flooding on property owned by other persons. Two concerns regarding off-site flooding were raised by Petitioners: first, the potential for flooding of the Petitioners' property; and, second, the potential for flooding of secondary systems connecting to Lake No. 7 such as private roads in the development. The project would violate the requirements of Section 40D-4.301(1)(a), Florida Administrative Code, which requires that a proposed project provide adequate flood protection and drainage, if raising the weir and berm elevation to 33.6 would cause the level of water in Lake No. 7 to move laterally up the bank and encroach on property owned by Petitioners. However, the Club has given reasonable assurances that the Petitioners own only to the "top of bank" and that raising the weir elevation to 33.6 would not cause water levels to rise above the "top of bank" of the lake. If it is determined in pending state circuit court proceedings that the Petitioners own beyond the "top of bank," any permit for the Club's project might have to be modified to avoid flooding the Petitioners' property. With respect to potential flooding of secondary systems, such as adjacent roadways, raising the elevation of water in Lake No. 7 would decrease the capacity of the storm sewers draining into the Lake. However, the proposed modifications would not increase the area of impervious surface in the drainage basin or decrease the size of the lake, and water levels in the roadways probably would not rise much higher than under present circumstances. The existing storm sewer system is only designed for a 10-year storm event, so the supplemental effect on roadway flooding from retaining a 100-year storm event in Lake No. 7 probably would be negligible. The Club gave reasonable assurances that any increase in water levels on the roadways from the proposed modifications would not be considered a significant adverse effect because it still would not affect public access. Sarasota County's land development regulations allow flooding in streets of up to 12 inches for a 100-year storm event, nine inches for a 25-year storm event, and six inches for a 10-year storm event. No portion of the proposed project area is within the 100-year floodplain. The project will not have an adverse effect on water quantity attenuation or cause flooding of the Petitioners' property or secondary systems, such as adjacent roadways. Petitioners have protested the effect that this project will have on water quality within Lake No. 7, itself. Surface water quality standards do not apply within a stormwater pond. Stormwater ponds are essentially pollution sinks intended to receive polluted runoff. Where there is no discharge from a pond, water quality treatment is irrelevant. Lake 7 is not a "water resource within the District" pursuant to Section 40D-4.301(1)(j), Florida Administrative Code, and potential impact on water quality in Lake No. 7 should not be considered. Section 40D-4.301(1)(j) limits the issues to be considered by the District to downstream water quality, water quantity, floodplain impacts, and wetlands impacts. The commingling of wastewater effluent treated to a level of advanced secondary or advanced waste treatment (reuse water) would improve water quality within a stormwater treatment pond at least 90 to 95 percent of the time. Stormwater is very low quality compared to reuse water. In most respects, reuse water also will be better quality than the well water presently being used to augment the pond. It is expected to be better quality than unimpacted water in the receiving waterbody with respect to nitrogen content and only slightly worse with respect to phosphorus content. The addition of reuse water should not promote more algal growth; rather, it should reduce the likelihood of algal growth. It also should not increase the incidences of fish kills in Lake 7. Nor should it alter the nutrient concentrations in Lake 7 so as to result in an imbalance of the natural population of aquatic flora and fauna. In the draft permit originally proposed to be issued to the Club, permit conditions required that water quality be monitored at the point of discharge to waters of the state. This requirement was eliminated from the revised permit as the District determined that it was not necessary in light of the modification of the system to retain the 100-year storm event. The subject design does not account for recovery of the water quality treatment volume within a specified period of time. However, there is no such requirement in District rules when a pond entirely retains the 100-year storm event, as is the case with this project. Even if there were a discharge from the surface water management system in a storm event up to and including a 100-year storm event, the Club gave reasonable assurances that water quality standards in the receiving waterbody would not be violated because of the effects of dilution. This project will not cause discharges which result in any violations of applicable state water quality standards for surface waters of the state. Based on a number of factors, including the peak rate factor, the curve number and the seasonal high water elevation, the water level in Lake 7 would reach an elevation of 33.57 if a 100-year storm event occurs. This results in the retention of the 100-year storm in Lake 7. The District only considers the 100-year storm event, by itself. It does not consider other rainfall events before or after it. However, the District does presume that ponds are at their seasonal high water level when the 100-year storm event occurs and that the ground is saturated. With respect to the seasonal high water level, there was substantial conflicting testimony. The Club's consultant used a seasonal high water level of 31.0' for Lake No. 7 in his calculations. This was based on a geotechnical engineering report prepared by Ardaman & Associates. A seasonal high water elevation of 31.0' was also used in the original permit application in 1985. In concluding that the seasonal high water level should be 31.0, the Ardaman report relied on several assumptions, including plugging of the underdrain and overflow weir and no discharges into or pumping out of the lake. These assumptions were made to establish an historical water level. The Petitioners' consultant disputed the determination in the Ardaman report that the seasonal high for Lake No. 7 was 31 on the grounds that the report indicated groundwater levels of 32.8 on three sides of the lake. He also felt that water levels would rise in the lake over time as a result of it being, allegedly, a closed system. While he did not have an opinion as to what the appropriate seasonal high should be, he felt it would be higher than 31 but lower than 32.8. However, he did no modeling with respect to calculating a seasonal high water level and would normally rely on a geotechnical engineer, such as Ardaman & Associates, to calculate seasonal high water levels. The District generally does not receive information as extensive and detailed as that included in the Ardaman report when it reviews permit applications. Among other things, the Ardaman report indicates a gradient across Lake No. 7 which makes the determination of the seasonal high for the lake difficult. The groundwater flow gradient results from the fact that the elevation of Lake No. 6 is approximately three feet lower than the elevation in Lake No. 7. The elevation determined by Ardaman may well be conservative in that the seasonal high of 31 is above the midpoint of the gradient. Although Lake 7 will be designed as an essentially closed system, it will have inflow from rainfall, surface runoff, introduction of reuse water and groundwater inflow, and outflows by way of evapotranspiration, withdrawal for irrigation purposes, and groundwater outflows. To alleviate any concerns about the validity of the seasonal high, it would be reasonable to include a permit condition requiring the Club to monitor the water level in Lake 7 on a daily basis, using staff gauges, after modification of the control structure. If such monitoring indicated that the seasonal high water level exceeds 31.0, the District could consider options to address that situation, including reducing the level at which reuse water is introduced into the lake or requiring water quality monitoring at the point of discharge to receiving waters. Groundwater quality is regulated by the Department of Environmental Protection, not by the District. The DEP permit issued to Sarasota County for disposal of reuse water at the Club golf course requires the installation of two groundwater monitoring wells, one in fairly close proximity to Lake No. 7. The Overlooked Pond There is a small retention pond northwest of Lake 7, near lot 113. Neither the Club nor the District considered the effect of the Club's late modification of its application on the retention pond northwest of Lake 7 and adjacent properties. Lake 7 and the retention pond to its northwest are connected by an equalizer pipe. As a result, water levels in the pond will be affected by water levels in Lake 7. There was no evidence as to the elevations of the banks of the retention pond. There was no evidence as to whether the modifications to the Club's application will result in flooding of properties adjacent to the pond. There was no evidence that the Club owns or controls the retention pond or the properties adjacent to it that might be affected by flooding that might result from the modifications to the Club's application.

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 denying the Club's amended application. RECOMMENDED this 19th day of October, 1995, in Tallahassee, Florida. J. LAWRENCE JOHNSTON Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 19th day of October, 1995. APPENDIX TO RECOMMENDED ORDER, CASE NO. 95-2196 To comply with the requirements of Section 120.59(2), Fla. Stat. (1993), the following rulings are made on the parties' proposed findings of fact: Petitioners' Proposed Findings of Fact. 1.-2. Accepted and incorporated. Accepted and incorporated to the extent not subordinate or unnecessary. However, there was other evidence from which it can be determined that Lake 7 is part of the Club's lease. Accepted and incorporated. However, there was other evidence from which it can be determined that Lake 7 is part of the Club's lease and from which the western extent of the Club's leasehold interests in Lake 7 can be determined. Accepted and incorporated. But the topographic survey, together with other evidence, does show the eastern extent of the Petitioners' property in relation to the "top of bank" of Lake 7 and the western extent of the Club's leasehold interests in Lake 7. Rejected as contrary to the greater weight of the evidence that uses must be "specifically authorized" in that the lease authorizes the use of the premises for a "golf course," which is presumed to include uses inherent to the operation of a golf course that may not be further specified in the lease, such as drainage facilities, like Lake 7, and facilities for irrigation of the golf course. Otherwise, accepted and incorporated to the extent not subordinate or unnecessary. Rejected as contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Rejected as contrary to the greater weight of the evidence that the Club does not pay for the maintenance of Lake 7, at least as between the Club and its lessor, which is the subject of the pertinent lease provision. (There was evidence as to a dispute between the Club and the Petitioners, or at least some of them, as to who is responsible for maintenance of land in the vicinity of the western extent of Lake 7 and the eastern extent of the Petitioners' property. Rejected as contrary to the greater weight of the evidence. Rejected as contrary to the greater weight of the evidence to the extent that there are "A" parcels between lots 115 through 120 and Lake 7. Otherwise, accepted and incorporated. Accepted and incorporated. Not clear whether all of the activities listed in the second sentence are done in the entire area up to the water's edge but, otherwise, accepted and incorporated. Accepted, but subordinate to facts contrary to those found, and unnecessary. Accepted; subordinate to facts found. Rejected. The intent of the parties is not clear and is the subject of litigation in state circuit court. 17.-18. Accepted that some probably used the words "to the water's edge"; others may have said "to the lake" or "to the approximate high water line." Regardless of what they said, the legal consequences are being litigated in state circuit court. Subordinate to facts contrary to those found, and unnecessary. 19.-20. Accepted and incorporated to the extent not subordinate or unnecessary.. Last sentence, accepted but subordinate and unnecessary. The rest is rejected as contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. The evidence was sufficient to place on Exhibit M-16 the boundary lines of the "A" parcels, as depicted on the Alberti boundary survey that was attached to the individual deeds to all of the "A" parcels, in relation to the "top of bank" of Lake 7 and other topographical features depicted on Exhibit M-16. The 0.679 acre total for the "A" parcels was merely transcribed from the Alberti boundary survey (probably incorrectly, as the boundary survey seems to indicate the acreage to be 0.674, plus or minus.) Rejected as contrary to the greater weight of the evidence. The modification itself would not cause the water level to rise. If, due to the combined influence of all the pertinent factors, the water level in Lake 7 rises, it will spread more than before the modifications, up to a maximum spread of approximately ten feet. Rejected as contrary to the greater weight of the evidence. The Club gave reasonable assurances that the spread would be contained within its leasehold interest. However, consideration would have to be given to modifying the permit if the state circuit court determines in the pending litigation that the easterly boundary of the "A" parcels lies to the east of the "top of bank." Accepted and incorporated to the extent not conclusion of law. Accepted. Self-evident and unnecessary. Accepted and incorporated. Accepted, but subordinate, and unnecessary. Accepted and incorporated. Rejected as contrary to the greater weight of the evidence. It does not prohibit it; it just does not authorize it. It provides that authorization may be obtained by permit modification. Accepted and incorporated to the extent not subordinate or unnecessary. 32.-36. Accepted but subordinate and unnecessary. (Evidence was presented at final hearing.) 37. Rejected as contrary to the greater weight of the evidence that discharges will be "likely." (Accepted and incorporated that no discharges are expected as a result of storm events up to and including a 100-year storm event unless preceding conditions predispose the system to discharge during a 100-year storm event.) 38.-39. Accepted but subordinate and unnecessary. (As for 39., very little construction will be required for the proposed project.) Rejected as contrary to the greater weight of the evidence. First, Lake 7 will not be "maintained" at 31'; rather, when it falls below 30.5', a half inch will be added. Second, it is not clear that the Ardaman report established an "artificially low seasonal high water level." (There is a hydraulic gradient across Lake 7 from east to west, approximately. The Ardaman report assumed no flow into or out of Lake 7; it also assumed no pumpage into or out of the lake.) Rejected as contrary to the greater weight of the evidence that it is based "solely" on that assumption. Accepted and incorporated that it is based on that and on other assumptions. Accepted and incorporated. Accepted but subordinate and unnecessary. (Evidence was presented at final hearing.) Rejected as not supported by evidence. Rejected as contrary to the greater weight of the evidence to the extent that the impact is obvious--the water level in the pond will be approximately equal to the water level in Lake 7. Rejected as contrary to the greater weight of the evidence. The modification itself would not cause the water level to rise. If, due to the combined influence of all the pertinent factors, the water level in Lake 7 rises, so will the water level in the pond. 47.-48. Accepted and incorporated. 49.-50. Accepted but subordinate and unnecessary. 51.-52. Accepted and incorporated. Respondents' Proposed Findings of Fact. 1.-7. Accepted and incorporated. 8. Rejected as contrary to the greater weight of the evidence in that there was more to the application than just substitution of reuse for well water. 9.-10. Accepted and incorporated. 11. Accepted and incorporated to the extent not subordinate or unnecessary. 12.-22. Accepted and incorporated. Rejected as not proven. (The two District witnesses disagreed.) Even if true, subordinate to facts contrary to those found. Accepted and incorporated. Accepted and incorporated to the extent not subordinate or unnecessary, or conclusion of law. Accepted and incorporated. Accepted and incorporated to the extent not conclusion of law. 28.-29. Accepted; subordinate to facts found, and in part conclusion of law. 30. Accepted. First sentence, incorporated; second sentence, subordinate to facts found, and in part conclusion of law. 31.-35. Accepted and incorporated to the extent not subordinate or unnecessary, or conclusion of law. Accepted and incorporated. Accepted and incorporated to the extent not subordinate or unnecessary, or conclusion of law. Accepted but subordinate to facts contrary to those found. 39.-40. Accepted and incorporated to the extent not subordinate or unnecessary. 41.-43. Accepted and incorporated. Accepted and incorporated to the extent not conclusion of law. Last sentence, accepted and incorporated to the extent not conclusion of law; rest, accepted but subordinate to facts contrary to those found, and in part conclusion of law. Accepted and incorporated to the extent not subordinate or unnecessary. Accepted, but subordinate, and unnecessary. Accepted and incorporated. First sentence, accepted but subordinate to facts contrary to those found; second sentence, accepted and incorporated to the extent not conclusion of law. Accepted and incorporated to the extent not subordinate or unnecessary. 51.-52. Accepted and incorporated. 53.-55. Accepted, but subordinate to facts found, and unnecessary. 56. Accepted and incorporated. 57.-62. Accepted and incorporated to the extent not subordinate or unnecessary. 63. Accepted and incorporated to the extent not conclusion of law.

WILLIAM A. BARRINGER, IRVIN C. DEGELLER, CARL H. PFORZHEIMER, AND A. CLARK RAYNOR vs E. SPEER AND ASSOCIATES, INC., AND DEPARTMENT OF ENVIRONMENTAL REGULATION, 91-002900 (1991)
Division of Administrative Hearings, Florida Filed:Stuart, Florida May 10, 1991 Number: 91-002900 Latest Update: Aug. 12, 1992

The Issue The issue for determination in this proceeding is whether Respondent, E. Speer and Associates, Inc. (the "Applicant"), should be granted a permit for the construction of a permanent docking facility pursuant to Sections 403.91-403.929, Florida Statutes, and Florida Administrative Code Chapter 17.

Findings Of Fact Whether Quantified Hydrographic Studies Are Necessary For All Marina Applications To Provide Reasonable Assurance That Flushing Is Adequate To Prevent Violations of Water Quality Standards Speer's Exceptions Nos. 1, 4, 5, 6, 7 and 8 in whole or in part take exception to the Hearing Officer's conclusion (stated as a finding of fact) that it is not possible to demonstrate adequate flushing without "quantifying flushing rates and pollutant dispersal rates using objective methods and appropriate hydrodynamic data." (R.O. at 20, 22-24, 47, 49-50, 54, 57-58; F.O.F. Nos. 33, 35, 38-39, 40, 43-45, 64, 66, and 69) It is clear from the tenor of the entire recommended order that the Hearing Officer believes that as a matter of law an expert's opinion is not sufficient to provide reasonable assurances that flushing will be adequate to prevent violations of water quality standards unless that opinion is based on quantified conclusions generated by objective methods and appropriate hydrodynamic data. (R.O. at 47, 49-50, 57-58) Thus, for example, the Hearing Officer opines that quantification of flushing rates and pollutant dispersal rates using objective measurements of appropriate hydrodynamic data is an essential element of the prima facie showing required to be made by the applicant. (R.O. at 47; C.O.L. No. 11) The Hearing Officer places great significance an the following excerpt from the opinion in 1800 Atlantic Developers v. Department of Environmental Reculation, 552 So.2d 946 (Fla. 1st DCA 1989), rev. den., 562 So.2d 345 (Fla. 1990): 1800 Atlantic filed 34 exceptions to the recommended order, most of which were denied in the Department's final order . . . . The final order approved and adopted most of the findings of fact and conclusions of law in the recommended order and denied the permit. The following stated rulings and reasons there for are significant to the issues on this appeal. (emphasis added) We must note at this point that there is no finding of fact in the hearing officer's recommended order that quantifies how productive the marine habitat may be in this case, and no record support for the suggestion that there would be some quantifiable diminution in the quality of the marine habitat attributable to this project [footnote omitted]. (emphasis added) Exception 23 filed by 1800 Atlantic challenged the hearing officer's finding that the project will adversely affect the conservation of fish and wildlife, fishing or recreational values, and marine productivity in the vicinity . . . The Department rejected this exception based upon the hearing officer's general statements, without any quantification whatsoever, of adverse effects upon these matters . . . (emphasis added) 1800 Atlantic, 552 So.2d at 951-952. I do not concur that 1800 Atlantic stands for the proposition that quantified hydrographic measurement of flushing is in all cases an essential element of a prima facie showing that a marina project will not cause violations of water quality standards. Notwithstanding the above noted statement of the court in 1800 Atlantic that "there is no finding of fact . . . that quantifies 'how productive the marine habitat may be' . and no record support . . . that there would be some quantifiable diminution in the quality of marine habitat attributable to [the] project," 552 So.2d 951, the court did not reject the finding that the project adversely affected the conservation of fish and wildlife, fishing or recreation values, and marine productivity. Indeed, had the court rejected the above finding due to lack of quantified findings the court would never have gone on to reach the issue of mitigation because in 1800 Atlantic mitigation could only become relevant if the applicant was unable to provide reasonable assurance that the project satisfies the public interest criteria of Section 403.918(2) (a), Florida Statutes. See Section 403.918(2)(b), Florida Statutes. I do agree that in some cases quantified hydrographic studies of flushing may be required in order to provide reasonable assurances. Thus, in Rudloe v. Dickerson Bavshore, Inc., 10 FALR 3426 (DER Case No. 87-0816, June 9, 1988), my predecessor held that a dye tracer study was necessary to provide quantitative information about dilution rates and directions on dispersion of pollutants emanating from a proposed marina site which was in "close proximity" to Class II waters approved for shellfish harvesting. 10 FALR at 3447-48. However, the need for such quantified studies must be determined on a case by case basis and is not required as a matter of law for all marinas. 5/ Far me to determine as a matter of law that experts may establish a fact only by certain types of evidence would be an unwarranted and unwise intrusion into the scientific domain of the expert. Thus, in Kralik v. Ponce Marine, Inc., 11 FALR 669, 671 (DER Final Order, Jan. 11, 1989), my predecessor held that expert testimony with regard to flushing does not lack credibility just because a hydrographic study had not been conducted. Of course, the finder of fact has the ultimate say on how much weight an expert opinion should be given if it is not based on a quantified study. Thus, whether an expert testifying on adequacy of flushing has conducted a quantifiable hydrographic study merely goes to the weight of the evidence. Kralik, 11 FALR at 671. I only conclude that a quantified hydrographic study for a proposed marina is not in all cases essential for a showing of reasonable assurances that water quality standards will not be violated. Accordingly, to the extent that the Hearing Officer's findings of fact state that a quantified hydrographic study is required in all cases as a prima facie element of a showing of reasonable assurance that a project will not violate water quality standards, I reject such statement as a mislabled and incorrect conclusion of law. Reasonable Assurance That Flushing Is Adequate To Prevent Violations of Water Quality Standards I read Speer's Exceptions Nos. 1, 3, 4, 5, 6, 7 and 8 in whole or in part as taking exception to the Hearing Officer's finding that under the facts of this case a quantified hydrographic study was needed in order to provide reasonable assurance that the project would not cause violations of water quality standards, and that because such a quantified hydrographic study had not been conducted, reasonable assurances had not been provided. (F.O.F. Nos. 33, 35, 38- 39, 40, 43-45, 64, 66 and 69) As noted by the Hearing Officer, the applicant's expert testimony concerning the adequacy of the flushing consisted of general statements describing visual observations of river and tidal flows which, together with past experience and knowledge of the general area of the project, formed the basis for the experts' opinions that a quantified hydrographic study was not necessary for this project. (R.O. at 22-23) Thus, far example, Mr. Charles C. Isiminger, accepted as an expert in marina design and hydrographic engineering testified that based on his knowledge of the area, its riverine and tidal flows, a hydrographic documentation was not needed to provide reasonable assurance that the project would not cause water quality violations. Mr. Isiminger also testified that any pollutants entering the water from the marina would be flushed out of the area within one tidal cycle. (Tr. at 65-66, 70, 77- 79, 93, 110, 125, 128, 134) Mr. Thomas Franklin, an environmental supervisor from the Department testified that: the hydrographic survey was not really necessary due to the location of the project being in open waters and in close vicinity to the Inlet with a large volume of tidal waters moving in this area, plus the fact that it was further enhanced by flushing due to the St. Lucie River being -- basically coming around Hell Gate point [sic] and funneling out into this estuary. (emphasis added) TR at 437. Other experts also testified that the area was well flushed and that a quantified hydrographic study was not needed in this case. (Jacqueline Kelly, Tr. at 187; John Meyer, Tr. at 319, 322, 341; Gerald Ward, Tr. at 44749) 6/ Speer asserts that the Hearing Officer's finding that a quantified hydrographic study is required in this case cannot stand in light of the unrebutted expert testimony that the marina site will be well flushed and that the rate of flushing provides reasonable assurances the water quality standards will not be violated. I have found no competent substantial evidence in the record which would support a finding that under the facts of this case a quantified hydrographic study is required. I did note that in Footnote 21 of the Recommended Order (R.O. at 20) the Hearing Officer states: Tidal range is only one of the types of data used to quantify flushing rates and pollutant dispersal rates. See TR at 78. Other appropriate data include: overall flow rates, mid tide flow, flow amplitude (the magnitude of the flow without regard to direction, i.e., speed as opposed to velocity), horizontal current distribution, downstream plume characteristics, and field verification using a dye tracer. All of this data is needed to fully describe and quantify flushing rates and pollutant dispersal rates. (citing testimony of Mr. Isiminger at Tr. 88-94) At first blush this may appear to be competent substantial evidence supporting a finding that a quantified hydrographic study is necessary in this case. However, when the testimony is read in its complete context, it is clear that Mr. Isiminger is testifying as to what is necessary to do a hydrographic study when one is needed, and is not testifying that such a study is needed in this case. (Tr. 88-94). I also note that the record contains a memo written by Dr. Kenneth Echternacht, a hydrographic engineer employed by the Department. (Tr. at 67-70) This memo was admitted without objection. (Tr. at 23) The memo states in part that "without . . . hydrographic documentation, reasonable assurance cannot be given that the project will not cause problems." (Tr. at 70; Pet. Exh. No. 10) 7/ Dr. Echternacht was not called as a witness at the hearing and the letter was not offered as evidence of the opinion of Dr. Echternacht or the Department at the time of the de novo hearing. To the contrary, the above noted testimony of Mr. Franklin and the testimony of Jacqueline D. Kelly, an environmental specialist of the Department accepted as an expert in evaluating impacts of environmental dredge and fill projects (Tr. at 187, 195; R.O. at 3), clearly establish that at the time of the de novo hearing the Department was of the opinion that further hydrographic documentation was not needed. The Hearing Officer noted that Mr. Meyer testified that the flushing is a "very, very complicated dynamic situation." (Tr. at 320). The testimony was as follows: Q. So you don't know for sure whether the currents here impact this at all or stay offshore from it? A. Oh, the currents definitelv affect it, and you do have interchange -- as I mentioned before, a very high rate of interchange on a daily basis on every tide. Q. Are you saying that the current that flows through here every day flows right through the site? A. We're dealing with two different things here. We're dealing with your currents, your general migration of waters from the estuary from the inland areas down. You're also dealing with tidal effects coming in and out, and it's a very, very complicated dynamic situation. For me to try to tell you exactly how these things work would be impossible without having a very, very long drawn-out expensive study done on the entire area, and I have not reviewed any studies like that. Tr. at 319-20 (emphasis added) When taken in its context it is clear that Mr. Meyer is testifying that there is a very high rate of exchange on a daily basis on every tide. The fact that he viewed the exact details of the flushing as very complicated in no way retracted his statement that there was a very high rate of exchange on every tide. My review of the record leads me to concur with Speer that no testimony, either on direct, cross-examination, or examination by the Hearing Officer, nor any other evidence was introduced to rebut the expert testimony presented by Speer and the Department that flushing on the site was adequate to provide reasonable assurance that water quality standards will not be violated. 8/ As a general rule, the trier of fact may not arbitrarily reject uncontroverted evidence as proof of a contested fact. Merrill Stevens Dry Dock Co. v. G. & J. Investments, 506 So.2d 30 (Fla. 3d DCA 1987), rev. den., 515 So.2d 229 (Fla. 1987); City of St. Petersburg v. Vinoy Park Hotel, 352 So.2d 149 (Fla. 2d DCA 1977); In Re: Estate of Hannon, 447 So.2d 1027 (Fla. 4th DCA 1984). This does not mean that a mere scintilla of unrebutted evidence is sufficient to establish a contested fact in an administrative hearing. At least in the context of administrative proceedings, the unrebutted evidence still must be competent substantial evidence to support a finding of fact. 9/ There is no suggestion that the Hearing Officer rejected the unrebutted testimony of the experts of Speer and the Department as not being competent substantial evidence. In fact, in the light of the testimony of Mr. Isiminger (Tr. at 65- 66), Mr. Ward ( Tr. at 447-449), Mr. Meyer (Tr. at 238- 239), and Mr. Franklin (Tr. at 345-350), it is beyond peradventure that there is competent substantial evidence to support a finding that flushing is adequate to provide reasonable assurance that the marina will not cause violations of water quality standards. It is clear from the context of the Recommended Order that the Hearing Officer believed that reasonable assurance had not been provided only because he believed that a quantified hydrographic study was required as a matter of law. Although I reject the Hearing Officer's conclusion that a quantified hydrographic study must be conducted as a matter of law for all marina applications, I must still determine whether a quantified hydrographic analysis is required under the facts of this case. In Rudloe v. Dickerson Bayshore, 10 FALR 3426 (DER Final Order, June 9, 1988) it was held that a hydrographic study was not adequate because it did not include a quantified dye tracer study. Id., 10 FALR at 3448. In Rudloe, as in this case, the marina was located in Class III waters, but near Class II waters. However, in Rudloe, the marina site was much closer to the Class II waters (approximately 1,700 feet in Rudloe (10 FAIR at 3430) as compared to approximately 8,000 feet in this case). (R.O. at 16, F.O.F. No. 26) Also, the Rudloe case is significantly different from this case in that competent substantial expert opinion was presented in Rudloe that the marina would adversely impact the Class II shellfish harvesting area. See Rudloe, 10 FALR at 3433-35, 3437-38 (testimony of DNR expert that operation of marina would result in closure of waters to the harvest of shellfish; testimony of Dr. Robert Livingston that the hydrographic drogue studies conducted were inadequate.) In this case, neither expert nor lay testimony was offered by Barringer to show that operation of the marina would result in violation of water quality standards or have any adverse impact on the Class II shellfish waters. 10/ I conclude that the facts of this case as found by the Hearing Officer are not sufficiently similar to the facts of Rudloe so as to justify holding as a matter of law a quantified hydrographic study is necessary to establish the required reasonable assurances. Since the record contains competent substantial evidence that flushing is adequate to provide reasonable assurance that the marina will not cause water quality violations, and since there is no competent substantial evidence in the record to support the Hearing Officer's contrary finding, I must accept the exception of Speer and reject the Hearing Officer's findings of fact to the contrary. In this case I note that I am not so much rejecting findings of fact as rejecting a conclusion of law. As I noted, the Hearing Officer's finding is really based on a conclusion of law which I reject. This leaves only unrebutted competent substantial evidence that there will be adequate flushing to provide reasonable assurance that the operation of the marina will not result in water quality violations. There is no rational basis to reject this unrebutted competent substantial evidence. Therefore, I must accept as proven that the applicant has provided the reasonable assurances that operation of the marina will not result in water quality violations. Merrill Stevens Dry Dock; City of St. Petersburg; Estate of Hannon; supra, Effect On Class II Waters Speer's Exceptions Nos. 7 and 8 take exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the marina would not have a "negative effect" an the Class II waters of the St. Lucie Inlet and the Great Pocket. (F.O.F. No. 43) Rule 17-312.080(6)(b), Fla. Admin. Code provides: The Department also shall deny a permit for dredging and filling in any class of waters where the location of the project is adjacent or in close proximity to Class II waters, unless the applicant submits a plan or proposes a procedure which demonstrates that the dredging or filling will not have a negative effect on the Class II waters and will not result in violations of water quality standards in the Class II waters. In this case expert testimony was presented by Speer and the Department that due to the distance of the marina site from the Class II waters (8,000 feet) the marina site was not in close proximity to the Class II waters, and due to the rapid flushing of the area, the construction and operation of the marina would neither have a negative effect nor would result in violations of water quality standards in the Class II waters of St. Lucie Inlet and the Great Pocket. (Isiminger, Tr. at 96, 126-27; Meyer, Tr. at 254-55) I find that the record contains no competent substantial evidence to rebut the evidence introduced by Speer and the Department that the marina will have no negative effect on Class II waters and will not result in violation of water quality standards in Class II waters. Accordingly, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersburg; In Re: Estate of Hannon; supra. Reasonable Assurance That Operation Of The Marina Will Not Result In Prop Dredging Or Violations Of The State Water Quality Criterion For Turbidity Speer's Exceptions Nos. 1, 2, 9-12, and 16 in whole or in part take exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the boat traffic from operation of the marina would not cause prop dredging or violations of the water quality criterion for turbidity. (F.O.F. Nos. 33-34, 45, 48, 52-53, 64, and 67) 11/ On one hand, there was testimony that the depths of the marina, in combination with the size of boats allowed in the various slips, would allow for a one foot clearance from the bottom of the boats to the bottom of the marina, and that this clearance, in combination with speed limits in the marina, would provide reasonable assurance that operation of the marina would not result in prop dredging or turbidity violations. (Isiminger, Tr. at 104-107, 118; Meyer Tr. at 263-65, 299, 304- 305; Kelly, Tr. at 189-190; Ward, Tr. at 460) On the other hand, Bruce Graham, admitted as an expert in marine biology testified that: "A large boat, three feet from the bottom, I think would resuspend sediment." (Graham, Tr. at 378). The Hearing Officer, noting that when asked if one foot clearance is sufficient to prevent prop dredging and resultant turbidity violations, a Department witness, testified: I would have to say that we simply don't have enough documentation to know this for a fact. We know that a foot gives us a degree of comfort that there will not be prop wash. In certain instances -- a tug boat, for instance, you know, with huge engines, you're going to have prop wash over a much -- over a large area and with probably much more than a foot of clearance. But for the normal, typical marina a foot, as I say, gives us a degree of comfort that we have settled on. Neyer, Tr. at 264. The Hearing Officer concluded that the witnesses of Speer and the Department could not explain the reasons or efficacy of the "one foot policy" except to say that in their experience the one foot policy was adequate to prevent prop dredging and turbidity violations. (R.O. at 28 n.35)0 The Hearing Officer thus found that Speer and the Department failed to "prove up" the one foot policy -- i.e., failed to elucidate and explicate the reason for the policy. 12/ Clearly the Hearing Officer placed more weight on the testimony of Mr. Bruce Graham than that of Isiminger, Meyer, Kelly and Ward. Since I cannot say that the testimony of Graham was not competent substantial evidence, I am not at liberty to reweigh the evidence or reject the Hearing Officer's finding of fact. See, Florida Dept. of Corrections v. Bradley, 510 So.2d 1122 (Fla. 1st DCA 1987); Heifetz v. Department of Business Regulation, 475 So.2d 1277, 1281 (Fla. 1st DCA 1985); Sections 120.57(1)(b)10., and 120.68(10), Florida Statutes. Speer contends that Barringer presented no evidence that prop dredging will cause sufficient turbidity to violate the state water quality turbidity criterion of 29 NTUs. 13/ That contention misses the point. The burden is on Speer to establish by the preponderance of evidence that reasonable assurance has been provided that operation of the marina will not result in violations of the water quality criterion for turbidity. Florida Department of Transportation v. J.W.C., Co., 396 So.2d 778 (Fla. 1st DCA 1981). The Hearing Officer, as the finder of fact, concluded that Speer failed to do so. Accordingly, I reject the exception of Speer and accept the Hearing Officer's finding of fact that Speer failed to provide reasonable assurance that operation of the marina would not cause prop dredging or violations of the state water quality criterion for turbidity. Manatee Impacts and the Public Interest Test Speer's Exceptions Nos. 13 and 17 take exception to the Hearing Officer's finding that Speer failed to do a quantified study of impacts to manatees and therefore failed to provide reasonable assurance that the marina will not have an adverse impact on manatees, their migratory patterns, and their habitat. (F.O.F. Nos. 61, 64 and 68) The Hearing Officer reasoned as follows: Instead of a traffic study, the Applicant and DER presented evidence in the form of general statements that manatees need not migrate north and south through the approach channel. According to the Applicant and DER, manatees can migrate across the project site by one of two alternative routes. They can migrate in one or two feet of water under moored boats and then under wave breaks on the north and east piers, or they can migrate in the shallow water landward of the west boundary of the project. That evidence was not persuasive and was controverted by competent, substantial, and persuasive evidence that manatees would be deterred from migrating under the project footprint by substantial obstacles in their path. Manatees migrating under the project footprint would be exposed to 86 or more moving boats with powerful engines and drafts of four to five feet in waters covering approximately 20,800 square feet. It could be argued, or course, that 86 or more boats would not be moving in and out of the marina at one time. However, it is impossible to estimate occupancy rates, length of stay, and frequency of boat trips without a traffic study. (R.O. at 35, n. 51) As Speer's exception notes, there was testimony that because of the width of the river and boat speed restrictions in the project area, there would be no adverse impacts an the manatee from the marina. (Kelly, Tr. at 162; Meyer, Tr. at 255-56, 331- 32; Isiminger, Tr. at 130) The St. Lucie/Jupiter/Hobe Sound waterways are a major travel corridor for manatees. (DER Exh. No. 4) Between 1974 and December 1990, there were ten water craft related manatee fatalities within the boating sphere of influence of the project. (DER Exh. No. 4) In order to reduce impacts on the manatees, the proposed permit contains the following specific conditions: S.C. No. 13: The permittee agrees to install and maintain a minimum of one manatee education/display on the main access pier during and after construction. S.C. No. 15: The permittee agrees that any collision with a manatee shall be reported immediately [to DNR and U.S. Fish and wildlife Service]. S.C. No. 18: The permittee shall post four (4) manatee area/slow speed signs, two of which would be spaced along the perimeter pier and two of which would be located on the outside of the marina for all boating traffic to observe within the marina facility. (DER Exh. No. 3) 14/ There was testimony that the piers, once constructed, would not impair the passage of manatees. (Isiminger, Tr. at 114- 115) On the other hand, there was some testimony that manatees may have to go around the project rather than through it. (Meyer, Tr. at 311) The existing boat traffic past the site of the project to the Inlet was "rough1y estimated" at 50 to 100 boats a day. (Meyer, Tr. at 337) The U.S. Fish and Wildlife Service determined that "while [the project] may negatively affect, it is not likely to jeopardize the continued existence of the West Indian Manatee." (Tr. at 120-21) The Hearing Officer concluded that reasonable assurance as to adverse impacts on manatees could not be provided absent a quantified traffic study. (R.O. at 35, n. 51) In Coscan Florida, Inc. v. Department of Environmental Regulation, 12 FAIR 1359 (DER Final Order March 9, 1990), the Department held that the information needed to determine a marina's impact on manatees and the necessary actions to mitigate such impacts must be decided an a case by case basis. For example, in Sheridan v. Deep Lagoon Marina, 11 FALR 4710 (DER Final Order, Aug. 24, 1989), 15/ a marina sought to expand by adding 113 new wet slips. The marina was required to develop a manatee protection plan far the surrounding portions of the Caloosahatchee River, all new slips were limited to sail boats until the manatee protection plan was implemented and enforced, and power boat occupancy was limited to 75% of the total 174 wetslips in any event. The marina also made available a wet slip for use by the Florida Marine Patrol. In this case there is evidence of significant boat related manatee fatalities in the boating sphere of influence of the proposed marina. There is also evidence of existing traffic of 50-100 boats per day past the project site. In view of the fact that this project would add 86 slips and a public fueling facility, it seems likely that that the project will significantly increase both boat traffic and the threat of manatee collisions. Accordingly, I concur with the Hearing Officer that there is competent substantial evidence to support a finding that further studies are needed to determine what, if any, additional manatee protection conditions are needed to provide reasonable assurance that manatees will not be adversely affected. I conclude that the applicant did not provide reasonable assurance that the operation of the marina will not have an adverse impact on manatees, their migratory patterns, and their habitat, and therefore failed to provide reasonable assurance that the project is not contrary to the public interest. Therefore, I reject the exception of Speer. Cumulative and Secondary Impacts Speer's Exception No. 15 takes exception to the Hearing Officer's finding that the applicant failed to provide reasonable assurance that there will be no adverse cumulative pacts created either by the cumulative effects of the object and existing similar projects, or by secondary pacts of the project itself. (F.O.F. No. 66) 16/ Cumulative impact analysis takes into consideration the cumulative impacts of similar projects which are existing, under construction, or reasonably expected in the future. Conservancy v. A. Vernon Allen Builder, supra; Section 403.919, Florida Statutes. Secondary impact analysis considers the impact of the project itself and of any other relevant activities that are very closely linked or causally related to the permitted project. Conservancy, 580 So.2d at 778; J.T. McCormick v. City of Jacksonville, 12 FALR 960, 980. 17/ Thus, in Conservancy the secondary impact analysis was required to consider the environmental impacts of development of 75 estate homes on an island where the development would be reasonably expected as a result of the permitted laying of a subaqueous sewer line. Similarly, in del Campo v. Department of Environmental Regulation, 452 So.2d 1004 (Fla. 1st DCA 1984), the Department was required to consider the environmental impacts of the foreseeable development of an island facilitated by the permitted building of a bridge to the island. In this case there is competent substantial evidence that there are other marinas located 1,750 feet downstream in Willoughby Creek, and 5,000 feet downstream in Manatee Pocket. (R.O. F.O.F. 31; Isiminger, Tr. at 112; Meyer, Tr. at 261) The record contains competent substantial evidence that the cumulative impact of the project and the existing marinas in Willoughby Creek and Manatee Pocket will not result in violations of state water policy. (Isiminger, Tr. at 125; Kelly, Tr. at 167) I cannot say that the testimony of Isiminger and Kelly on cumulative impacts is not competent, substantial evidence. In light of the fact that there is no competent substantial evidence to indicate that cumulative impacts would result in water quality violations, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersbur; In re: Estate of Hannon; supra. As to secondary impacts, the Hearing Officer pointed out that Speer did not introduce any evidence as to whether there would be secondary impacts to water quality as the result of further development or increased utilization of the uplands facilities. (See F.O.F. 66, n.59, R.O. at 39) Such further development or increased utilization of upland facilities is reasonably foreseeable and would be very closely linked or causally related to the building of an 86 slip marina with public fuel services. As noted above, the applicant has the burden of providing reasonable assurances as to cumulative and secondary impacts. Brown v. DER, supra; Conservancy, supra. However, neither the pleadings nor the pre-hearing stipulation raised the issue of the adequacy of the secondary impact analysis. In a case such as this where the Department's notice of intent to issue a permit has been challenged by a third party, the applicant's prima facie case need only include the application and the accompanying documentation and information relied on by the Department as the basis of its intent to issue. Florida Department of Transportation v. J.W.C., 396 So.2d 778, 788 (Fla. 1st DCA 1981). The petitioner challenging the permit must identify the areas of controversy and allege a factual basis for its contentions that the applicant did not provide the necessary reasonable assurances. J.W.C., 396 So.2d at 789. See also Woodholly Assoc. v. Department of Natural Resources, 451 So.2d 1002, 1004 (Fla. 1st DCA 1984). Since Barringer did not identify this issue and did not allege any factual basis for a contention that the secondary impact analysis was inadequate or incorrect, I may not rule on the issue in this order. Miscellaneous Exceptions To Findings of Fact Speer's Exception No. 14 takes exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the project will have no adverse impact on (1) the relative value of functions being performed by areas affected by the project, including seagrasses, shell fish, and fin-fish, and (2) recreational and commercial values in the vicinity. (F.O.F. No. 64) Speer contends that this finding is not supported in the record by competent substantial evidence and is contrary to unrebutted testimony of Ms. Kelly and Mr. Isiminger. (Kelly, Tr. at 159, 161-62, 165-67; Isiminger, Tr. at 73) I cannot say that the testimony of Isiminger and Kelly is not competent, substantial evidence, and I find no evidence in the record to rebut the testimony of Kelly and Isiminger. Therefore, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersburg; In re: Estate of Hannon; supra. Speer's Exception No. 3 takes exception to the Hearing Officer's finding that Speer failed to provide a current water quality analysis. (F.O.F. No. 35) A water quality analysis was submitted in April of 1990, shortly after the permit application was filed. (R.O. at 2, 19; F.O.F. No. 34) I find no competent substantial evidence in the record to suggest any reason for believing that the water quality has changed since April of 1990. I agree with Speer that, absent some specific reason for believing that the water quality has changed since the date of a study conducted contemporaneously with the permit application, there is no requirement to provide an updated water quality analysis. RULINGS ON EXCEPTIONS TO CONCLUSIONS OF LAW Need For Quantified Hydrographic Study Speer's Exceptions Nos. 1, 7 and 9, in whole or in part, take exception to the Hearing Officer's conclusions of law that a quantified hydrographic study was needed to provide reasonable assurances that the operation of the marina would not result in violations of water quality standards and would would not have a negative effect on Class II waters. For the reasons stated in Parts III(1), (2) and (3) above, I accept this exception and reject the above noted conclusions of law. Introduction Of Issues Not Set Forth In Pleadings Or Pre-Hearing Stipulations Speer's Exceptions Nos. 1, 2, 3, and 5, in whole or in part, take exception to the Hearing Officer's consideration of issues of (1) the need for a quantified hydrographic study, (2) the proximity of the site to Class II waters, (3) turbidity and prop dredging, (4) cumulative impacts, and (5) the need for a quantified study on manatee impacts. For the reasons set forth in Part 111(6) above, I agree that, absent waiver, a petitioner challenging an intent to issue a permit may not raise issues at the hearing which were not raised in the pleadings or pre-hearing stipulations. However, in this case the issue of manatee impacts was raised in the pleadings, and Speer was on notice that it had the burden of proof on that issue. As to the other issues, even if I accepted far the sake of argument that they were not raised in the pleadings or pre-hearing stipulations, Speer failed to timely object to the raising of these issues at the hearing and therefore waived any objection. See Sarasota County and Midnight Pass Society v. Department of Environmental Regulation, 13 FAIR 1727 (DER Final Order, April 4, 1991). Therefore, I reject the above exceptions. Proximity To Class II Waters Speer's Exception No. 2 takes exception to the Hearing Officer's conclusion of law that Speer was required to submit a plan which demonstrated that the marina would not have a negative effect on Class II waters. (C.O.L. Nos. 12 and 13) I do not agree that where a proposed marina site is 8,000 feet from Class II waters and where the site is rapidly flushed as noted in Parts 111(1), (2) and (3) above, that the site is in close proximity with the Class II waters within the meaning of Rule 17-312.080(6), Fla. Admin. Code. Accordingly, I accept this exception and reject the above note conclusion of law. Public Interest Test Speer's Exception No. 4 takes exception to the Hearing Officer's conclusion of law that Speer failed to provide reasonable assurance that the project was not contrary to the public interest. (C.O.L. Nos. 17 and 20) For the reasons set forth in Parts III(4) and (5) above, I reject this exception. Cumulative Impacts Speer's Exception No. 5 takes exception to the Hearing Officer's conclusion of law that Speer failed to provide reasonable assurances that cumulative impacts would not result in water quality violations, and that such assurances could only be provided by a quantified study. For the reasons set forth in Parts III (1), (2), (3) and (6) above, I accept this exception and reject the above noted conclusions of law. Modification Of Permit Conditions Speer's Exception No. 6 takes Exception to the Hearing Officer's conclusions of law Nos. 24-34. These conclusions of law concern questions of the authority of the Hearing Officer and me to modify the conditions of the permit. I agree with Speer that since none of the parties have requested any modifications, these conclusions of law are irrelevant. 18/ Therefore I accept the exception and reject the above noted conclusions of law as irrelevant. Miscellaneous Speer's Exception No. 8 in part takes exception to the Hearing Officer's conclusion that Speer and the Department failed to provide reasonable assurance as to prop dredging and turbidity violations because neither Speer nor the Department sufficiently proved the basis for the one-foot clearance policy. For the reasons set forth in Part III(4) above, I reject this exception. Speer's Exception No. 8 in part takes exception to the Hearing Officer's conclusion that the question of whether mitigation is adequate is a question of law. I agree with the Hearing Officer and reject this exception. See 1800 Atlantic Developers v. Department of Environmental Regulation, 552 So.2d 946, 955 (Fla. 1st DCA 1989).

Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is recommended that Respondent, Department of Environmental Regulation, enter a Final Order denying the application for a permit to construct the proposed project and denying the request for determination of improper purposes.

VINCENT J. WOEPPEL vs DEPARTMENT OF ENVIRONMENTAL REGULATION, 92-004063 (1992)
Division of Administrative Hearings, Florida Filed:Lake Wales, Florida Jul. 06, 1992 Number: 92-004063 Latest Update: Apr. 16, 1993

Findings Of Fact On December 12, 1991, Petitioner applied to the Respondent for a permit/water quality certification to grade and level, in stages, approximately 20,000 square feet or 0.45 acres of lake front to remove and prevent the formation of berms and depressions in the exposed lake bottom adjacent to his property. The project site is located at 3955 Placid View Drive which lies along the shoreline of Lake Placid, a natural waterbody in Highlands County, Section 24, Township 37 South, Range 29 East. Lake Placid is not an aquatic preserve, and is not an outstanding Florida water. It has been designated as a Class III waterbody. Petitioner's unsubdivided lot lies at the western end of Lake Placid. The shoreline measures approximately 203 feet. The western lot line also measures 203 feet, and fronts on Placid View Drive. The water level of Lake Placid has receded in recent years which allows large expanses of what was historically lake bottom to become beaches, lawns, and areas of habaceous marsh. The specific project which the Petitioner proposes calls for the leveling of the berms and depressions which form on the exposed lake bottom from collected water, which stagnates and permits various noxious creatures, including mosquitoes, to breed in them. The berms and depressions are approximately six inches high or deep and between one and three feet wide, and generally extend the length of the shoreline. The proposed area affected is approximately 20,000 square feet or 0.45 acres of lake front, although Petitioner proposes to actually level a much smaller area in stages of approximately 2,000 square feet on an "as needed" basis. No material other than sod in the beach area is proposed to be brought from or removed to off-site locations. Petitioner is highly sensitive to mosquito bites. The area proposed for leveling was previously cleared of vegetation without authorization. Very little revegetation of the shoreline has occurred since the area was cleared. Vegetation colonizing the beach, at present, includes pennyworts (Centella asiatica and Hydrocotyle umbellata) and water- hyssops (Bacopa sp.) Blue green algae was observed in the depressions which have formed along the shore since the clearing. Fauna observed on-site included gulls (Larus sp.), small fish in the adjacent lake shallows, and water-boatmen (Order Hemiptera) in the depressions. An area landward of the wetlands considered here was also cleared previously and is proposed to be seeded. An adjacent, uncleared shoreline was vegetated with primrose willow (Ludwigia sp.), cattail (Typha sp.), flat sedge (Cyperus odorata), and other wetland species for an almost 100% plant coverage. The Petitioner proposes to use a small tractor in leveling of the shore which will cause turbidity in the lake water. No turbidity controls were proposed by the Petitioner. Petitioner failed to provide reasonable assurances that the turbidity caused by the earthmoving equipment in areas presently above water would not cause degradation of water quality in Lake Placid; would not contribute to the long-term degradation of water quality in the lake caused by upland runoff that would flow into the lake without benefit of retention or filtration by shoreland vegetation (freshwater herbaceous habitat) which would be permanently removed under Petitioner's proposal. Nutrients such a nitrogen and phosphorus and pollutants such as pesticides, herbicides and other chemicals commonly used in lawn and garden care would be included in the runoff, and would have an adverse impact on fishing and marine productivity in the lake. The project would have a minor adverse impact on erosion and soil stabilization in the area surrounding the lake. Petitioner has failed to provide reasonable assurance that the proposed project is not contrary to the public interest. Petitioner can mitigate the project by eliminating the use of heavy equipment and substitute hand equipment to smooth out ruts, berms and depressions in jurisdictional areas.

Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the Petitioner's application for Wetland Resource Regulation permit be DENIED.

J. A. ABBANAT AND MARGARET M. ABBANAT vs. WILLIAM O. REYNOLDS AND DEPARTMENT OF ENVIRONMENTAL REGULATION, 84-001508 (1984)
Division of Administrative Hearings, Florida Number: 84-001508 Latest Update: Mar. 08, 1985

Findings Of Fact This cause commenced upon the filing of an application (#440816855) by William O. Reynolds to construct a weedgate and fence in front of a dead-end canal in Bogie Channel serving the Atlantis Estates Subdivision on Big Pine Key, Monroe County, Florida. The proposed project would be constructed in Class III waters of the State of Florida. An existing unpermitted weedgate exists in this location and the applicants for the proposed project are attempting to obtain a proper permit for a modified version of the existing gate. Applicants for the proposed project are property owners in the Atlantis Estates Subdivision, whose properties are adjacent to the canal in front of which the proposed weedgate and fence are to be located. An ad hoc committee of certain of the Atlantis Estates Subdivision owners had met and decided to proceed with an application for the proposed project. However, not all subdivision landowners agreed with the proposed project, most specifically the Petitioners Margaret and J. A. Abbanat. William Reynolds signed and submitted the application for the project, and indicated in a notarized affidavit in tie application that he was acting as agent for property owners in the Atlantis Estates Subdivision. Reynolds is one of those property owners, specifically lot #17. There are 26 lots adjoining the dead-end canal. At hearing, twenty (20) of the property owners indicated their support for the project by submission of notarized statements. The members of the ad hoc committee and the vast majority of property owners authorized and supported the project and the filing of the application by Reynolds. The permit application for the proposed weedgate and fence was submitted due to the problems caused by dead floating sea grasses and weeds (wrack) collecting in the Atlantis Estates Subdivision canal. Wrack has collected in large quantities in the canal in the past, and at such times problems such as stench, difficulty in navigation, and fish kills have occurred. Accumulated wrack in dead-end canals can cause water quality problems, including fish kills, and may also negatively affect navigation in the canal. Wrack is likely to collect in the Atlantis Estates Subdivision canal due to its dead-end configuration and due to its location, since the open end of the canal faces the east and the prevailing winds in this area are from the east. The weedgate and fence should cause no state water quality violations, should not unreasonably interfere with navigation where it is located at the mouth of the canal, and should actually improve water quality and navigation within the canal. Water quality outside of the weedgate and fence should not be significantly decreased since the winds, tides, and currents should allow the wrack to drift away into open water and not accumulate, especially not to the extent the wrack would accumulate in the canal. According to a proposed DER permit condition, the weedgate and fence must not cause a state water quality violation, and therefore if a water quality violation were caused by the project in waters outside the weedgate and fence, enforcement action would be required to correct the problem. If the weedgate and fence becomes a navigational hazard, it is to be removed according to a proposed DER permit condition. The application was not certified by a Professional Engineer. The Department's South Florida District Office did not seek such a certification from the applicant. The proposed project consists of a stainless steel framework with vinyl covered wire fence to prevent wreck from drifting into the canal and a gate through the fence constructed of the same type of materials with a cable and counter weight system for opening and closing the gate. As proposed, the weedgate and fence should not create a navigational hazard, but should that occur, the proposed DER permit condition would require removal.

Recommendation Based upon the foregoing Findings of Fact, and Conclusions of Law, it is, therefore, RECOMMENDED that the State of Florida Department of Environmental Regulation grant the application and issue the permit subject to the following conditions: That the weedgate and fence be removed if at anytime a navigational hazard develops or the structure fall into disrepair. That the weedgate and fence must not cause a state water quality violation outside of the fence and if such water quality violations were caused by the project in water outside the weedgate and fence, enforcement action would follow.

HENRY ROSS vs CITY OF TARPON SPRINGS AND DEPARTMENT OF ENVIRONMENTAL PROTECTION, 10-003351 (2010)
Division of Administrative Hearings, Florida Filed:Tarpon Springs, Florida Jun. 21, 2010 Number: 10-003351 Latest Update: Apr. 27, 2011

The Issue The issue to be determined in this case is whether the City of Tarpon Springs (“City”) is entitled to a industrial wastewater facility permit for its proposed discharge of demineralization concentrate into the Gulf of Mexico adjacent to Pasco County, Florida.

Findings Of Fact The Parties Henry Ross is a resident of Tarpon Springs. In his petition for hearing, he alleges that he is a recreational fisherman and a "consumer of fish taken from the area" where the proposed wastewater discharge would occur. He presented no evidence at the final hearing to prove these allegations. Neither the City or the Department stipulated to facts that would establish Ross's standing. The City of Tarpon Springs is a municipality in Pinellas County and the applicant for the industrial wastewater permit that is challenged by Ross. The Department is the agency charged by law with the duty, and granted the power, to regulate the discharge of pollutants into waters of the State. The Proposed Permit - General Due to the cost of obtaining potable water from Pinellas County Utilities, the City decided to look for another source of drinking water. In February 2004, an alternative water supply plan was developed by the City’s Office of Public Services which analyzed potable water supply options. It determined that the withdrawal and treatment of brackish groundwater represented the best option for the City. The proposed permit authorizes the City to discharge industrial wastewater into waters of the State. The wastewater is demineralization concentrate, which is produced when RO technology is used to remove salts from brackish water to convert it to potable water. The wastewater would be produced in conjunction with the operation of a not-yet-constructed WTP that would supply public drinking water to the residents of the City. The City must also obtain a consumptive use permit from the Southwest Florida Water Management District for the proposed withdrawal of groundwater. Whether the Town is entitled to a consumptive use permit is not at issue in this proceeding. The industrial wastewater permit would authorize a maximum daily discharge of 2.79 million gallons per day ("mgd") of RO concentrate. The initial operation of the WTP, however, is expected to discharge 1.05 mgd. The RO concentrate would be transported via a force main from the WTP in the City to an outfall in Pasco County. The outfall would discharge the wastewater into a canal which is already being used for the discharge of cooling water from Progress Energy Florida, Inc.’s Anclote Power Generation Facility. The outfall would be 50 feet north of the point in the canal where Progress Energy is required to demonstrate compliance with its own permitting requirements, so as not to interfere with Progress Energy's ability to demonstrate compliance. There is a floating barrier in the channel north of the proposed point of discharge, and a fence along the side of the canal, to prevent swimmers, boaters, and persons on foot from getting near the Progress Energy power plant. The floating barrier and fence would also prevent swimmers, boaters, or pedestrians from reaching the proposed discharge outfall and the area of the canal where the discharge will initially mix. After being discharged into the canal, the wastewater would become diluted and flow northward, out of the canal and into the open waters of the Gulf. The prevailing currents in area would most often force the wastewater south toward Pinellas County and the mouth of the Anclote River. To determine the characteristics of the wastewater, the City's consultants collected water from the three proposed well fields for the new WTP and ran the water through a small, pilot-scale RO unit to generate an RO concentrate that is representative of the proposed RO discharge. It was determined that eight constituents of the wastewater would likely be present in concentrations that would exceed applicable state water quality standards: aluminum, copper, iron, gross alpha (a radioactivity measurement), total radium, selenium, nickel, and zinc. The Mixing Zones The Department may authorize mixing zones in which a wastewater discharge is allowed to mix with the receiving waters. See Fla. Admin. Code R. 62-4.244. Within the mixing zone, certain minimum water quality criteria must be met. At the outer boundary of the mixing zone, the applicable state water quality standards must be met. In this case, the water quality standards for Class III marine waters are applicable. The City's consultants analyzed the wastewater, receiving waters, and other factors and used an analytical model to simulate a number of mixing scenarios. In cooperation with Department staff, a separate mixing zone was established for each of the eight constituents that are not expected to meet water quality standards at the outfall. The largest mixing zone, for copper, is 1,483.9 square meters. The smallest mixing zone, for nickel, is 0.7 square meters. The mixing zones are conservatively large to assure sufficient mixing. Under most conditions, the mixing is expected to occur in a smaller area. Toxicity Analysis Among the minimum criteria that must be met within a mixing zone is the requirement to avoid conditions that are acutely toxic. See Fla. Admin Code R. 62-302.500(1)(a). A wastewater discharge is tested for potential acute toxicity by exposing test organisms to the undiluted discharge and determining whether more than 50 percent of the organisms die within a specified time period. The test organisms, mysid shrimp and silverside minnow, are sensitive species. Therefore, when a discharge is not acutely toxic to these organisms, it can be reasonably presumed that the discharge would not harm the native organisms in the receiving waters. The acute toxicity test for the proposed RO concentrate indicated zero toxicity. The Department requested that the City also analyze the potential chronic toxicity of the proposed discharge. A wastewater discharge shows chronic toxicity if exposure to the discharge adversely affects the growth and weight of the test organisms. The tests performed on the representative discharge showed that the proposed discharge of RO concentrate would not create chronic toxicity in the mixing zones. Petitioner’s expert witness, Ann Ney, did not review the toxicity analyses or other water quality data that were submitted to the Department by the City. However, she expressed a general concern about a salty discharge that could create stratification in the canal with higher salinity at the bottom of the canal that might be hypoxic (little or no dissolved oxygen). The more persuasive evidence shows that salinity stratification, or a hypoxic condition, is unlikely to occur. The proposed permit requires the City to conduct quarterly chronic toxicity tests. The permit also requires the City to periodically test the water and sediments for any unexpected cumulative effects of the discharge. Evaluation of Disposal Options Florida Administrative Code Rule 62-620.625(6) requires that an applicant for a permit to discharge demineralization concentrate must investigate disposal options potentially available in the project area. The City evaluated blending the discharge concentrate with the City's re-use water irrigation program or with the City’s domestic wastewater discharge into the Anclote River. The RO concentrate was too salty for irrigation use and there was an inadequate volume of domestic wastewater available throughout the year. In addition, the Anclote River is an Outstanding Florida Water and, therefore, is afforded the highest water quality protection under Department rules. See Fla. Admin. Code R. 62-4.242(2). The City also looked at underground injection but that was economically unreasonable and there was concern about upward migration of the discharge. It was economically unreasonable to discharge the concentrate farther out into the Gulf. Anti-degradation Analysis For a proposed new discharge, a permit applicant must demonstrate that the use of another discharge location, land application, or recycling that would avoid the degradation of water quality is not economically and technologically reasonable. See Fla. Admin. Code R. 62-4.242(1)(d). As discussed above, the City investigated other disposal options, but they were not economically or technologically reasonable. An applicant for a permit authorizing a new discharge must demonstrate that any degradation is desirable under federal standards and under circumstances that are clearly in the public interest. See Fla. Admin. Code R. 62-302.300(17). In determining whether a proposed discharge is desirable under federal standards and under circumstances that are clearly in the public interest, the Department is required by Rule 62-4.242(1)(b) to consider the following factors: Whether the proposed project is important to and is beneficial to public health, safety or welfare (taking into account the policies set forth in Rule 62-302.300, F.A.C., and, if applicable, Rule 62-302.700, F.A.C.); and Whether the proposed discharge will adversely affect conservation of fish and wildlife, including endangered or threatened species, or their habitats; and Whether the proposed discharge will adversely affect the fishing or water-based recreational values or marine productivity in the vicinity of the proposed discharge; and Whether the proposed discharge is consistent with any applicable Surface Water Improvement and Management Plan that has been adopted by a Water Management District and approved by the Department. The proposed project is important to and is beneficial to public health, safety or welfare because it would provide drinking water for the public. In addition, the treatment and use of brackish groundwater converts otherwise unusable water into a valuable resource. The use of brackish water avoids the use of water in the surficial aquifer that is used by natural systems, such as wetlands. The Florida Legislature has found that the demineralization of brackish water is in the public interest, as expressed in Section 403.0882, Florida Statutes (2010): The legislature finds and declares that it is in the public interest to conserve and protect water resources, provide adequate supplies and provide for natural systems, and promote brackish water demineralization as an alternative to withdrawals of freshwater groundwater and surface water by removing institutional barriers to demineralization and, through research, including demonstration projects, to advance water and water by-product treatment technology, sound waste by-product disposal methods, and regional solutions to water resources issues. The proposed discharge would not adversely affect conservation of fish and wildlife. Because the discharge is not toxic to sensitive test organisms provides reasonable assurance that the native fish and other aquatic life would not be adversely affected by the discharge. The only identified threatened or endangered species that frequents the canal waters is the endangered Florida Manatee. Manatees use the canal because of its relatively warm waters. Manatees come to the surface to breathe and they drink fresh water. There is no reason to expect that a manatee moving through the mixing zones would be adversely affected by the RO concentrate. The Florida Fish and Wildlife Conservation Commission, which has primary responsibility for the protection of endangered and threatened species, did not object to the proposed permit. Manatees and many other aquatic species use seagrasses as food or habitat. There are no seagrasses in the area of the canal into which the RO concentrate would be discharged, but there are dense seagrass beds nearby. The proposed discharge would have no effect on the seagrasses in the area. The proposed discharge would not adversely affect fishing or water-based recreational values or marine productivity in the vicinity of the proposed discharge. Because the proposed discharge is non-toxic and would meet Class III water quality standards before reaching the closest areas where humans have access to the canal and Gulf waters, there is no reason to believe that the proposed discharge would be harmful to humans. The proposed discharge would not adversely affect recreational activities, such as swimming, boating, or fishing. Petitioner presented the testimony of two fishermen about fishing resources and water flow in the area, but no evidence was presented to show how the proposed discharge would reduce marine productivity. Petitioner contends that the proposed discharge would adversely affect the Pinellas County Aquatic Preserve. However, the aquatic preserve is two miles away. The proposed discharge would probably be undetectable at that distance. It would have no effect on the waters or other resources of the aquatic preserve. With regard to the requirement that the proposed discharge be consistent with an adopted and approved Surface Water Improvement and Management Plan for the area, there is no such plan.

Recommendation Based on the foregoing Findings of Fact and Conclusions of Law it is RECOMMENDED that the Department issue a final order determining that Petitioner lacks standing, and approving the issuance of the industrial wastewater facility permit to the City.

SUNLAND ESTATES, INC. vs. DEPARTMENT OF ENVIRONMENTAL REGULATION, 88-001813 (1988)
Division of Administrative Hearings, Florida Number: 88-001813 Latest Update: Nov. 30, 1989

Findings Of Fact Petitioner is the owner and developer of a parcel of land located on the eastern side of the northern end of Key Largo, Monroe County, Florida. Located in the middle of that parcel is a dead-end east-west canal approximately two feet deep at its eastern end where it opens to the Atlantic Ocean and approximately twenty feet deep at its western dead-end. The canal is approximately fifty feet wide. A plug at the mouth of the canal previously prevented boat traffic from entering and exiting the canal. Petitioner's predecessor in title permitted the plug to partially erode, and Petitioner's president had some of the boulders which helped form the plug removed. The digging of the canal, the placement of the plug, and the partial removal of the plug were performed without benefit of state and federal permits. Petitioner's development plan is that twenty single-family homes will surround the canal, with each home being serviced by a septic tank and a boat dock. On the oceanside of the partial plug is a small depressed area which was dredged at the same time that the canal itself was dredged. Surrounding that depressed area is very shallow water. Petitioner proposes to remove the plug from the existing canal and shallow the canal to a uniform depth of -10 feet and two years later to a uniform depth of -6 feet. Petitioner further proposes to dredge an access channel from the mouth of the canal northward for a distance of approximately 480 feet where it would join with an existing channel. The access channel proposed to be dredged would be approximately fifty feet wide and six feet deep at low tide. The area to be dredged to create the access channel is classified as Class III waters, is within the Florida Keys Special Waters, and is also classified as Outstanding Florida Waters. The waters outside the existing canal where Petitioner proposes to dredge the access channel are also located within John Pennekamp State Park, the site of a natural coral reef. Due to the disparity in depths between the shallow waters outside the existing canal which are only one or two feet deep and the depth of the existing canal which is as deep as twenty feet, the canal itself experiences a very long flushing time. The lengthy flushing time causes the waters in the existing canal to fall below minimum state water quality standards The area proposed to be dredged for the navigational access channel is thickly vegetated by a productive seagrass and algae community. The area is in excellent condition, and the seagrass and algae community is very healthy. The seagrass and algae communities serve as habitat for thousands of organisms, including juvenile lobster and other small plants and animals; serve as a food source for animals; stabilize sediments through their root structures; reduce pollution by filtering pollutants from the water; are a natural feature of the John Pennekamp State Park, and are part of the ecological unit that is important for the survival of reef corals. The proposed dredging of the access channel would destroy an area of approximately one-half acre. Excessive turbidity is often a problem with dredge and fill activities, and reef coral need clear water for survival. Once dredged, the proposed access channel would not be expected to revegetate. Further, the proposed dredged channel will violate state water quality standards for dissolved oxygen. The proposed navigational access channel would connect the mouth of the existing canal with the Post channel to the north of Petitioner's property. The Post channel dug in approximately 1971 is also six feet deep, violates state water quality standards for dissolved oxygen, and has never revegetated even though replanting of vegetation has been attempted. The destruction of the one-half acre area of healthy productive habitat would adversely affect fish and other marine wildlife, resulting in a decrease in fishery production and marine productivity. The residential subdivision will be a source of pollutants from, among other things, septic tanks, fertilizers, stormwater run-off from paved areas, boats, and boat engines, into the existing canal in violation of state water quality standards for Class III waters and would lower the ambient water quality of the adjacent Outstanding Florida Waters. The long flushing time of the canal, even if shallowed as proposed, will result in the waters of the canal failing to meet state water quality standards. Any pollutants or organic material entering or blown into the canal will remain in the canal to be broken down by bacteria which consume oxygen, resulting in low dissolved oxygen in violation of state water quality standards. Further, pollutants will be exported periodically into the receding waters outside the canal, resulting in degradation of those Outstanding Florida Waters. The project is not in the public interest since the project will result in water quality violations and in the destruction of an area of highly productive shallow water habitat. The adverse cumulative impacts of allowing riparian landowners along the Florida Keys to dredge access channels are overwhelming.

Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is, therefore, RECOMMENDED that a Final Order be entered: Denying Petitioner's application for a permit for its proposed project, and Dismissing Intervenor Izaak Walton League, Mangrove Chapter, as a party to this proceeding.

ARMAND J. HOULE vs. DEPARTMENT OF ENVIRONMENTAL REGULATION, 87-001469 (1987)
Division of Administrative Hearings, Florida Number: 87-001469 Latest Update: Apr. 29, 1988

Findings Of Fact In September, 1985, Armand J. Houle purchased an 80 acre tract located eight miles east of the Naples toll booth on State Road 84 and approximately two miles north of Alligator Alley. The purpose of buying the property was to mine the limestone rock thereon, through a borrow pit, for the purpose of selling it as road base to the State of Florida Department of Transportation for use in the construction of 1-75 (Alligator Alley extending from Naples to the Florida east coast). While no contract has existed or currently exists, correspondence between the Department of Transportation and counsel for the Petitioner indicates that approximately 800,000 cubic yards of fill will be required in the immediate area and that Petitioner's proposed borrow pit would be the ideal source of this rock. Prior to making the purchase, Mr. Houle's associate, Raymond Chester, contacted both the Department of Transportation concerning the potential use of the rock and representatives of the Department of Environmental Regulation. The response he received from these agencies led him to, believe that a borrow pit might well be permitted and the effort should be pursued. After Mr. Chester and Mr. Houle became partners in the property, they contacted county officials and received zoning and other local permits for the facility. It was only after this, when DER was approached again that the applicants were advised a permit would not be issued. Mr. Houle agrees that, if the permits as requested were granted, he would accept a prohibition against further development of the property after removal of the rock and fill, would allow access to the restored lakes to the public for fishing and recreation; would agree to an appropriate restoration plan for the site; and would ensure compliance with the restoration plan stipulated by the Department. After the property was purchased in late 1985, Mr. Houle approached Daniel W. Brundage, the vice-president of an engineering firm in Naples, with a view toward developing the property in question as a borrow pit. Plans were developed for application for permits with the County and Mr. Brundage, consistent therewith, visited the site on several occasions. He found some vegetation off from the site which could be related to wetlands and contacted a representative of DER with whom he went to the site to look it over. This agency representative, Mr. Beever, concluded that the property was a jurisdictional wetland. Mr. Brundage nonetheless felt confident enough to begin work with the County to secure a permit to convert this land, classified as agricultural, to mining property. Consistent with his efforts, the request for conversion went through a four step process on the way to the County Commission which included approval by (1) the Water Management Advisory Board, (2) the Environmental Advisory Council which recommended same changes accepted by the Petitioner, (3) the Subdivision Review Committee, and (4) the Coastal Area Planning Council. All four subagencies recommended approval and thereafter the County granted its permit for work to begin. Assuming all permits are issued, the property will be developed in two stages. In stage one the site will be cleared of vegetation, and the top soil on Phase I, the western 40 acre parcel, removed and used to construct a berm around the entire perimeter of the site as well as between the two 40 acre parcels. The berm will be entirely within property boundaries and used to isolate any water removed from the active phase within the site so that it does not flow onto adjoining property. The eastern 40 acre tract, (Stage II) will be used for water storage during the excavation of Stage 1. It is anticipated that no water will leave the site during construction of either stage with the exception of extraordinary waterfall during rainfall or hurricane. Before any water is discharged, it will go into a storage configuration so that any sediment therein would settle to the bottom before discharge. The discharged water will be filtered through hay bales or filter screens to avoid any turbidity in the surrounding water. The design of this holding capacity in the filter system is sufficient to accommodate the water of a 25 year storm. As Stage I is completed, Stage II will be opened, and the ground water from Stage II pumped back to Stage I for storage. A similar storage and filtration system will be utilized around Stage I. Primary access to the property will be along the western boundary of 8 Mile Canal, but if this is not allowed, Petitioner proposes to build a single span bridge across the 8 Mile Canal at 40th Street to allow access to the property. After the lime rock has been excavated, the berm will be removed and the side of the property graded to form the banks of a 56 acre lake for recreational purposes. The edge of the lake will be a meandering slope at a ratio of 10:1 which will be assured by survey to be in compliance with the County plan. The lake, which will have a maximum depth of 20 feet, will be excavated at a depth ratio of 2:1 from the edge of the slope to the bottom of the lake. During excavation and prior to restoration, heavy equipment will be used for the removal of the rock such as drag lines, back hoes, motor graders, and bulldozers and an area within the boundaries of the site will be isolated and set up for fueling and maintenance. It will be floored with a membrane to prohibit oil and fuel from getting into the ground as a result of accidental spills. Storage tanks for fuel and oil will be above ground and available for immediate inspection. Waste facilities will be in the form of porta-potties and any water falling in this maintenance area will be drained to a low sump within the membraned area for storage until evaporation or safe removal. In the event of a heavy rainfall, water can be stored and anti-sedimented and cleaned and, if necessary, operations can be temporarily stopped. Mr. Brundage indicates that he has never seen any standing water on the site during his five visits nor has any standing water ever been reported to him. He is aware of no historical or archaeological sites on the property, and at no point would rock be mined within 50 feet of the property line. Dr. Durbin Tabb, a botanist, was retained by the Petitioner to prepare a plan for restoration of the site after mining operations were complete. In preparing his plan, he visited the site on several occasions finding varying plant life, much of which was grasses and rushes. In the north was a pine lowland where he saw palmettos scattered in the grassland as well as a few dwarf cypress trees. He also observed a small cluster of cabbage palms in the southern portion of the eastern tract and noted that the currently existing berm along the eastern boundary of the eastern tract is currently being invaded by exotic plant life including the Brazilian pepper. Dr. Tabb found little evidence of recent surface water accumulation; mollusk residue showed no evidence of recent viability; and he found no crawfish burrows which, if present, would show a water table near the surface. Other visitors to the site, however, did find crawfish burrows. The marsh soil shows that, at some time in the past, it was wet enough to support a soil-forming community. This is no longer' the case according to, Dr. Tabb. The process was stopped by the formulation of the Golden Gate Canal System in the 1960's. The existing marsh does, however', hold sufficient water to support the growth of muhli grass. Dr. Tabb's restoration plan is his best estimate of how the property can be restored to its previous condition by replanting native species found in the area. The program will include littoral zone vegetation to provide shelter and a feeding zone along the water's edge which does not now exist. The plan calls for the saying of the marsh soil. Since neither DER nor the client responded to his plan, when submitted, with any suggestions or corrections, he assumed it was approved. Dr. Tabb, who is also an expert in estuarian biology and zoology, concluded that the area on which this site is located is a very poor habitat for deer and panther. The red cockaded woodpecker has no trees on the property which it specifically desires and the property is a poor or nonexistent habitat for the indigo snake and the Everglades snake. It might, however, constitute a habitat for the Cape Sable seaside sparrow, but this bird has never been seen in this inland area. Panthers cross the area as do bears, but the presence of the excavated lake would be no more hindrance to them in their crossing than would the presence of Alligator Alley and the proposed 1-75. The area with sawgrass and muhli grass, which is dominant throughout the Golden Gate area, is called a "dry prairie" as opposed to a "wet prairie." While some of the same plants exist, it is somewhat different in that there are no viable wetlands wildlife organisms currently existing on the property. In Dr. Tabb's opinion, the property has lost its wetlands characteristics and only the marsh soil's water retention permits the life of the grasses currently existing. Wading birds would use the site later but do not currently utilize the area where excavation would take place. In Dr. Tabb's restoration plan, the slope to the lake would be replanted with saw and muhli grasses down to the litoral zone. From there on to the water, a palette of normal wet grasses would be planted to serve as feeding sites and roasting sites for the birds. In addition, an island planted with willows would be constructed off shore in the lake. Deer currently visit the area. They are not currently supported on the land though Mr. Barnett, of the Game and Fresh Water Fish Commission, indicated that they come out of the pine flats at night to feed on the grasses on the prairie. These deer form a large portion of the food chain for the panther, and Dr. Tabb does not consider it conceivable that the project, replanted and restored, would in any way adversely impact the Florida panther or the birds in issue here. In Dr. Tabb's opinion, it is questionable whether the site comes under the jurisdiction of DER based on the grasses present because he cannot find the water connection to confer jurisdiction. Dr. Tabb has not seen standing water on the site as he has seen on two other sites within the area where DER has granted permits for rock pits. On a site like this, the vegetation changes with the seasons. This site is not now connected to the canal along Alligator Alley by vegetation. There may have been a vegetation connection in the past, but as one goes up toward the site from the canal, the grass changes gradually from low pineland grasses found on higher ground to the lower sawgrasses found on the site in question. In Dr. Tabb's opinion, if Mr. Houle's property is to be considered a wetland, it is a transitional wetland. Turning to the issue of loss of habitat, if one assumes that portion of the property that will be converted to a lake will be denied to the panther, this is not the case for the deer which, in this area, is considered to be aquatic. Any denial of the lake area would constitute a very small negative impact compared to what is going on in other areas of Collier County. Admitting that there is a requirement to consider the cumulative impact of a project, in Dr. Tabb's opinion, this project would constitute a "may impact" situation. There is no definitive evidence as to what would happen, and he would be more concerned if the area were now a good panther habitat. It is not, however, and in fact it is no more than a habitat for the grasses which grow there. As to the wetlands issue, the only sign of exotic plant invasion is in the disturbed area around the canal which was installed approximately 18 years ago. The absence of these exotic species is, in Dr. Tabb's opinion, a clear indication that there is no flowing or standing water since the site is too dry for the germination of the seeds. There will be some removal of the biomass by the excavation of the lake. This biomass, consisting of grass primarily, is consumed by fire every year or so and insects eat it as well. Admittedly, some of the biomass is being eaten by animals of some nature and that which is converted to a lake will be removed. There is a trade-off, however. Dr. Martin Roessler, a marine biologist, prepared a report, on the water quality of the adjacent 8 Mile Canal, and other water bodies in the area. In preparation of his report, he took water samples in the areas in question, read literature on the water quality in the area, and looked at water quality data provided by U.S. government agencies and private companies. On the several visits he made to the site, he has not seen any surface water. The first time he could get water only in the adjacent canal, and he also got some water from the land borings done by Dr. Missimer on the site. Dr. Roessler is familiar with State standards for water quality and, in his opinion, the turbidity standards would not be disturbed because there was no water on the ground to be sheet flow. All water was at least three feet underground and, in addition, Petitioner has agreed to properly sod or otherwise treat the berms he will build to prevent erosion and any resultant turbidity either off-site or in the 8 Mile Canal. Dr. Roessler also does not believe the project would violate the oil and grease standards. There is nothing inherent in the mining process to bring into play oils and greases except for the possible problem in refueling and maintenance operations. In that regard, Petitioner has shown how he will provide against that by placing a membrane to prevent any oil, grease or other contaminant from getting into the ground. This area does not contain the organic mulch which produces natural oils and greases. The water near the surface of the lake will contain sufficient dissolved oxygen to meet State standards without problem. In the summer months when the dissolved oxygen count is low, generally, the lake bottom water may not meet State standards, but that happens quite frequently, naturally, across the entire area. Dr. Roessler believes that the dissolved oxygen requirements of 2.5 at the surface and .5 at the bottom will most likely be met in the lake created by this project. Concerning the biochemical oxygen demand (BOD), he concludes the operation in the quarry will not artificially decrease the available oxygen below the required amount. The BOD demand in this area would not be threatened by the lake. As to the iron standard and other toxic substances, Dr. Roessler does not believe that the project will create a violation of the standard nor will any runoff increase dissolved iron in adjacent waters. Hydrogen sulfide and pharasulfide standards will similarly not be violated. Sulfides are found only in trace amounts, if at all, in natural waters. In deep limestone lakes the chemical structure is not conducive to the formation of the acidic compounds. In short, Dr. Roessler believes the water in the mine would be very similar to that found in other rock quarries in the area. These lakes are a dominant portion of the recreational fresh water fishing availability. This instant lake also will, in time, upon development of the food chain for the fish, become an equivalent fishing habitat. Dr. Roessler concurs with Dr. Tabb regarding the flora on the site, which he observed himself. This site is 15 to 18 miles from marine or estuarian waters and to reach them one would have to go down a series of canals and past a saline dam to the coast. Any runoff from the site in question would have, if any, a minuscule effect on marine waters. This site was originally a wet prairie which was drained by the Golden Gate Canal System. As such it is a relatively poor habitat for life forms generally found in cypress wetlands. Creation of this lake will, in the opinion of Dr. Roessler, enhance the game, fish, and recreational activity of the area. It would be a benefit to the animal population to have a water source for drinking during drought. There would be no adverse effect on public health, safety or welfare. Turning to the major issue of water, Dr. Thomas Missimer, a hydrogeologist specializing in ground water, visited the site, examining the canal on the east side, and the soils and rocks exposed. He took soil borings and examined the site hydrology to see what fluctuations occurred in the water levels due to rainfall. Mr. Missimer, took numerous readings from September 18 through November 5, 1987 during a period of wet weather including a tropical storm. He carefully compared the site geology to other sites he had studied and compared the flow of water through the soil. He compiled existing information on chemistry in the streams in the area to see what the natural conditions were. He looked at other man-made lakes in the area which were previously borrow pits. As a result of his studies, he concluded that the groundwater level throughout the entire period never got higher than three feet below the land's surface and often was five feet below. During the previous July through September, 34 inches of rain fell in the area which was, in his opinion, average to above average. There is some evidence, however, to indicate that rainfall in the area was approximately 33 percent below average during the period. Nonetheless, Mr. Missimer took a measurement the day after a tropical storm had deposited three inches of water on the land. The water level at that time was still three feet below land level, and there was no standing water. Both the three foot and the five foot level are well below the top of the berm sloped at 10:1 as is proposed in the restoration plan submitted by Dr. Tabb. This site has, from a hydrological standpoint, been greatly affected by the installation, of the 8 Mile Canal and the canal system to the north. As, a result of this activity, standing water has not existed for many, years since the dredging of those canals. If de-watering is a necessary portion of the mining plan, any waters removed thereby would be retained in the impoundment area described by Mr. Brundage and switched back and forth. As proposed, the plan can completely avoid any impact to off-site property by water runoff. Construction of the pit and the lowering of the water level thereby will not have a major impact on the groundwater in the surrounding areas. Any effect would taper off as the distance increased from the site and would be of little significance. This proposal would also have little, if any, impact on groundwater quality. In Mr. Missimer's opinion, water quality is currently good and will stay good. This type of rock mine is very common in the area incident to construction. Some have been used as a source of potable water by The City of Naples; by Deltona Utility Company for Marco Island; and the south area of the County. These resources are still being used. There is little difference between those currently being used as potable water sources and the proposed lake here. Mr. Missimer also indicates the project will have little impact on the sheet flow of water. Sheet flow no longer exists here because of the canals and roads already existing. If there were a sheet flow created by a very heavy rain, this pit would have no impact on it. The water level in the lake will be approximately the same as exists in the ground currently and in the 8 Mile Canal. There should be no shoaling in the canal due to the project, and the presently existing spoil bank on the west side of the canal already prevents flow into the, canal from this land. If this pit is properly constituted and maintained, and if proper mining procedures are followed there should be no effect on the 8 Mile Canal to the east or the Alligator Alley Canal to the south. There is no surface water connection currently existing between this site and either canal. As to the issue of dissolved oxygen, the currently existing groundwater on the site and in the surrounding area has little or no dissolved oxygen in it. Water coming into the lake will be groundwater low in dissolved oxygen, which is identical to the water which currently goes into the canal system. The canal gets very little oxygen from the wind because it is so narrow. The lakes to be constructed, on the other hand, will get a large amount of oxygen from the 56 acres of water exposed to the open air. Consequently, construction of the lakes would increase the dissolved oxygen content of the water in the area, at least in the lakes, down to a level of several feet. This is a positive factor. Mr. Missimer recognizes, however, that during the dry seasons, when the lake is fed solely by groundwater generally low in dissolved oxygen, the lake water which has been converted to surface water may fail to meet the Department's surface water standards for dissolved oxygen. Warmer weather generally results in lower dissolved oxygen readings and, admittedly, Respondent's readings were taken in December when the dissolved oxygen levels are higher. As a result, the comparative samples which were taken in December are not necessarily indicative of what will be the situation in the lake, year- round. Respondent's witnesses present a more dismal picture of the effect of Petitioner's proposed project. Mr. Bickner, an Environmental Supervisor with DER's Bureau of Permits and himself an expert in water quality, zoology, and ecosystem biology, first became involved with this project while the permit request was being processed in late 1986. This application was a standard form project because of the quantity of material to be excavated. As a part of his processing, Mr. Bickner requested evaluations of the project from other agencies and divisions within DER and, on the basis of his personal evaluation and the recommendations he received, concluded that the application was not permittable. He recommended it be denied. Mr. Bickner considered Petitioner's application under the provisions of Chapter 403.918, Florida Statutes, which requires a two step evaluation. In the first step, the project must be determined to meet water quality standards. If it does, as a second stage, the project must be determined not to be contrary to the public interest. The major water quality standard in issue here was that of dissolved oxygen along with that concerning BOD and other deleterious substances. The water body involved was classified as a Class III Water under the provisions of Rule 17-3.121, Florida Administrative Code, since it was designed to be a recreational, fish and wildlife habitat. The standards contained in the statute and the rule relate to surface water as opposed to groundwater and, as to the public interest question, Chapter 403 provides a list of seven factors which must be evaluated. In this determination the agency has wide latitude and no one factor is controlling. In evaluation, agency personnel try to look at the project overall. Specifically, the project cannot cause or contribute to an existing water quality violation. In evaluation, agency personnel do not look at the project by itself. They must keep in mind that other projects exist or are proposed for the area. This is known as the cumulative impact of the project which is provided for in Section 403.919, Florida Statutes. As to the variance requested, this is also provided for by statute. The criteria require that the petition be based on some specific ground. In the instant case, the ground utilized by Petitioner was that there was no alternative to the dissolved oxygen level proposed. Granting of a variance is totally within the discretion of the Department even if Petitioner can show grounds therefor. Mr. Bickner was at the site only once. He approached from the south. At the low end of the approach was a mixture of wetlands and upland vegetation, but as he got toward the site the upland species dropped off and only the wetland species only remained. These were primarily sawgrass, cattails, and the like. He was satisfied that there was no obvious break in jurisdiction, and the testimony of Mr. Beever confirmed that jurisdiction over the site was gained through the wetlands character of the property from the site down to the Alligator Alley Canal, which is considered a water of the state. The site consists primarily of sawgrass and muhli grass with minor amounts of other grasses. The site seems to rise toward the 8 Mile Canal where there is an invasion of Brazilian peppers and other exotic species. Mr. Bickner was looking for upland species and found only one specimen of one species, a few of another, and no invasion of slash pine on the site at all. As a result, he concluded that the site was not an upland site. There was no standing water on the site at the time Mr. Bickner visited it, but the soil was wet to the surface. In addition, there was a large number of recently dead shells in low spots which had held water. There were some tracks of a large animal and a large number of smaller animal tracks and scats (scats are animal droppings). He also saw some birds which were too far away to identify and observed what he thought were crayfish tunnels near the cypress trees. Mr. Bickner found evidence of dried periphyton widely scattered over the site. Periphyton, an algae which attaches itself to other plants and which in times of inundation, forms sheets across the water connecting one plant to another, is a sign of previous inundation. The other plants on the site were not showing water deprivation stress, and there was no evidence of upland species invasion. All of this leads Mr. Bickner to conclude that the area has plenty of water and this opinion was enhanced by the lushness of the plants' growth. This, along with the high diversity of plant life, indicated to him a healthy ecosystem. To Mr. Bikner, the fact that the area was not currently inundated is not significant. In this particular area there are wet and dry seasons and, even in the dry season such as existed at the time of his visit, the soil was wet. The signs he saw indicated to him there has to be standing water on the site at some time. His visit was in January, which is well within the dry season. As to water quality, Mr. Bickner does not believe that the water quality standards will not be violated. In fact, by the nature of the project, Petitioner has, in Mr. Bickner's opinion, assured that it will be violated. A 20 foot deep pit must, in his opinion, result in low levels of dissolved oxygen below standards. Any water below seven foot in depth has little dissolved oxygen. Most dissolved oxygen is in the surface water, and there is little exchange between deep and surface waters. As a result, he concludes that the groundwater has low dissolved oxygen, a fact confirmed by Mr. Missimer. Dissolved oxygen is the only source of oxygen for fish and aquatic animals. Without dissolved oxygen, the fish die. There are currently no fish on the property. Mr. Bickner was also concerned with the biochemical oxygen demand which would further reduce the oxygen levels in the water. He was further concerned with the hydrogen sulfide levels coming from deterioration of plant material in the bottom of the pit, and iron which he found to be already in the groundwater. Mr. Bickner contends that during construction of the pit petro- chemicals will be introduced into the water, and that during the construction period the on-site water will have increased turbidity which will most likely be transmitted off-site as the pit is de-watered. There are management procedures which can reduce the risk, but none can avoid it entirely. Mr. Bickner is satisfied that the water quality standards will not be met. It is so found. Mr. Bickner also evaluated the property from the public interest standpoint, and in that regard he is satisfied there is a substantial potential for damage to adjacent properties by de-watering. Based on his experience and observation of other projects, he is satisfied there is no way to keep people employed on the site from using adjacent property for parking and vehicle maintenance. The witness believes that the 56 acres of habitat removed by the lake, and the remaining acres, which will be replanted, will be permanently impacted. While he admits that the property as it currently exists, may not be a prime habitat for the panther, there is some evidence which indicates panthers do cross it. He is concerned that the applicants submission here does not sufficiently answer all the questions as to impact on the public interest. The mechanics of the maintenance yard, soil storage and other potential areas of trauma are not explained satisfactorily, and Mr. Bickner does not see how all that is proposed can fit on the site. As a result, in his opinion, there must be some off-site impact. As to cumulative impact, since the valuable rock does not lie only under Petitioner's property, owners of the surrounding property may want to mine their properties as Petitioner proposes to do. If that happens, Mr. Bickner cannot explain how the Department can deny these subsequent applications. If the current application is permitted, taken together with the others, there would be a serious effect on the panther population. This opinion is not supported by evidence, however. If the public interest test is the only basis for disqualification of the project, (here the water quality test is also not met) a permit can still be granted if the applicant agrees to take appropriate mitigation steps at the site. Mr. Bickner is of the opinion that the applicant's mitigation plan to create the 100 foot wide shelf around the lake is not the same type of system which currently exists, will not fulfill the same function as the present property, and is not sufficiently large to replace what is being lost. One basis for granting the variance suggested by the Petitioner was the public interest, (the material was to be used for a public road), and the other was that there was no alternative way to get the material. While it is possible the rock would be used for public road, Mr. Bickner was concerned no assurances were given by the Petitioner that it would be. No contract has been signed yet, and Mr. Bickner is not satisfied that the letter from the Department of Transportation, indicating the rock there would suit its purpose, is sufficient indication that a contract would be signed. There is a possibility of making the pit shallower, which would permit the dissolved oxygen content of the lake water to meet state standards, but even if that problem were solved, Mr. Bickner is not satisfied that Petitioner has met the public interest test. Respondent has granted three permits and a variance to the Department of Transportation to build a portion of I-75 across Alligator Alley in Collier County. These permits are for the dredging of canals parallel to the roadway and to develop a borrow lake of 73.1 acres to be excavated to a depth of from 6 to 9.7 feet. The variance in question applies to all three projects and relates to the dissolved oxygen level. The DOT variance was applied for on the basis that no practical means for avoidance of the pollution existed. The Department of Transportation did not request a variance for BOD or for toxic and deleterious substances or iron. Mr. Bickner, admitted that these permitted projects would possibly have the same problem of oils and greases as he foresees with Petitioner's project. Nonetheless, he concludes that Petitioner's project should not be permitted, even though the Alligator Alley canals are already below standards, because to do so would contribute to a currently existing violation. Mr. James Beever, an Environmental Specialist with the Department of, Environmental Regulation, visited the site on several occasions, both on the ground and from the air. He observed much of the same flora and fauna observed by the other visitors who testified in this case and took color photographs of the area which portray the character of the property. All of the plants he discovered on the site are on the DER jurisdictional list and, on at least one occasion, from the air, he saw standing water on the site. In his opinion, the property is a fresh water wet prairie system which is admittedly drier than it should be. The plants he saw on the site indicate the jurisdiction of DER if there is a connection to other waters of the state, and in Mr. Beever's opinion, there is connection through the flow of sheet water south from the site to the I-75 (Alligator Alley) canal; then, east to the 8 Mile Canal; then south to the Fuqua Union Canal which empties southwest to the Gulf of Mexico. In his opinion, therefore, this is definitely jurisdictional land, and it is so found. The site supports an underground system of roots as well as the upper portion of the, plants existing thereon. He observed periphyton and many other animal tracks and scats. He also saw signs of regular inundation such as numerous snail shells, and he is satisfied there is no indication of a change in the area from the wetlands to an upland area. Admittedly, the area has been dry for a while. Even after Hurricane Floyd in 1987, there was no standing water. The site is, in his opinion, definitely productive, however. The vegetation existing thereon stabilizes the soil and provides food for snails, insects and crayfish which are on the bottom of the foodchain for other life forms on the property. The grasses provide a habitat for animals such as cotton rats, roosts for birds, pollen for insects, all which, themselves, become food for the larger animals. This wetland is a part of a large wetland prairie system and part of the Fuqua Union drainage basin, and acts as a filter for the water system for the area. According to Mr. Beever, most borrow pits like this are located on uplands which then provide rain water lakes. The instant pit, however, is in a wetlands area and if built, he believes, will engender violations during the mining operation. Groundwater coming in will contain iron and hydrogen sulfide which will combine with the dissolved oxygen in the water and further deplete the already low oxygen levels. All of this will constitute a violation of the rules regarding waters of the state since the waters within the pit would fall within that category. Mr. Beever is also concerned with the `bridge over the 8 Mile Canal and the turbidity connected with its construction and removal. In substance, Mr. Beever is convinced that construction of the project will create violations of the water quality standards for the area. As to the public interest, the wetlands character of the site will be completely lost. The vegetation will be removed, and the animals utilizing it will either leave or be destroyed. After, construction, some natural healing will occur, but a long-term maintenance program will be required to provide even different functions for the land than those which currently exist. In that regard, Mr. Beever is convinced that the applicant's proposed restoration plan is not acceptable. It will not replace the lost functions of the site; it will replace the species removed with a different ecosystem; it will provide a habitat for different species of animals and birds; it will adversely affect the shoaling and erosion in the lake itself (this is found to be without merit); it will have some adverse effect on the property of others; and will have an adverse cumulative impact on the area. The habitat will not be used any more by endangered species such as the wood stork and the panther. Even assuming, arguendo, the plans were suitable, in Mr. Beever's opinion, the project would not work here because of the lack of information on what the actual water level of the lake will be. The plant species proposed may not remain because of possible changes in water level in the lake. In addition, the marl berms will dry out over the three years of their life while the pit is being worked, and form a location for a lot of invasive upland plants. Much of Mr. Beever's concern is shared by Mr. Barnett, of the Game and Fresh Water Fish Commission, who indicated that birds now frequently use the area for nesting and feeding because of its wetlands character. Endangered species such as the Florida panther cross it from time to time as does the Florida black bear. Human encroachment reduces the panther's territory and reduces the area for forage of deer, which are the principal food of the panther. The bigger issue, however, is the cumulative impact. The 80 acres is not so important by itself, but to permit its removal would set a precedent for future encroachment by others. Mr. Barnett's experience is that restoration plans are quite often not successful. Even the successful ones, however, replace the removed system with a different system, and the species which now use the property would find it much less desirable as changed. Specifically, the bear, the deer, and the panther would find it unusable as proposed. At the present time, the deer spend their days in the pines forest to the north of the property, coming out onto the area, in question only at night to feed. It is during the night that the panther stalks. As presently constituted, this property is of no benefit to the wood stork or the red cockaded woodpecker. The Cape Sable sparrow could use it but does not. The development of Golden Gate Estates to the north and east and south of the property has a two pronged effect on the area in question. The southern portion of Golden Gate Estates has been abandoned, but the central and northern portions will be developed. On the one hand, it is likely that the increased population to the north and east will make the Petitioner's property less desirable and make access to it more difficult for the wildlife currently utilizing it. On the other hand, removal of the northern and central portions of Golden Gate from usable area for the panther and other species make it more important that Petitioner's area, which Barnett claims is not likely to be developed, remain as an animal habitat to offset the encroachment of the development area. There is no evidence to support this prediction of non- development, however. History tends to indicate otherwise.

Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is, therefore, RECOMMENDED that Petitioner be issued a dredge and fill permit as requested and a variance to the state water quality standards as identified in the request. RECOMMENDED this 29th day of April, 1988, in Tallahassee, Florida. ARNOLD H.

BRENDA B. SHERIDAN vs DEEP LAGOON BOAT CLUB, LTD., AND DEPARTMENT OF ENVIRONMENTAL PROTECTION, 98-003901 (1998)
Division of Administrative Hearings, Florida Filed:Fort Myers, Florida Sep. 04, 1998 Number: 98-003901 Latest Update: Feb. 02, 2000

The Issue The issue in DOAH Case No. 98-3901 is whether Respondent Deep Lagoon Boat Club, Ltd., is entitled to a maintenance dredging exemption from environmental resource permitting. The issue in DOAH Case No. 98-5409 is whether Respondent Deep Lagoon Boat Club, Ltd., is entitled to an environmental resource permit for the construction of a surface water management system.

Findings Of Fact The Parties Respondent Deep Lagoon Boat Club, Ltd. (Applicant), owns and operates Deep Lagoon Marina. In DOAH Case No. 98-3901, Petitioner and Intervenor challenge Applicant's claim of an exemption to maintenance dredge three canals serving the marina. In DOAH Case No. 98-5409, Petitioner challenges Applicant's request for an environmental resource permit to construct and operate a surface water management system on the uplands on which the marina is located. By stipulation, Petitioner has standing. Intervenor is a nonprofit organization of natural persons, hundreds of whom reside in Lee County. The primary purpose of Intervenor is to protect manatees and their habitat. Many of the members of Intervenor use and enjoy the waters of the State of Florida, in and about Deep Lagoon Marina, and would be substantially affected by an adverse impact to these waters or associated natural resources, including manatees and their habitat. Deep Lagoon Marina is within the jurisdiction of the South Florida Water Management District (SFWMD). By agreement with SFWMD, Respondent Department of Environmental Protection (collectively, with the predecessor agency, DEP) is the agency with permitting jurisdiction in DOAH Case No. 98-5409. The Marina Deep Lagoon is a short, largely mangrove-lined waterway that runs north into the Caloosahatchee River. The Caloosahatchee River runs west from Lake Okeechobee past Fort Myers to the Gulf of Mexico. Deep Lagoon Marina is on Deep Lagoon, less than one-half mile from the Caloosahatchee River. Deep Lagoon Marina comprises uplands and three canals adjoining MacGregor Boulevard south of downtown Fort Myers. Deep Lagoon Marina presently consists of 61 wet slips, 200 dry slips, and other marina-related buildings. One of Applicant's predecessors in interest dredged the three canals in the 1950s or 1960s, and a marina has existed at this location since that time. As a result of a purchase in 1997, Applicant owns the uplands and either owns the submerged bottoms of the canals or has a legitimate claim to such ownership. The attorney who examined the title at the time of the 1997 conveyance testified that the canals are entirely landward of the original mean high water line, so that the then-owner excavated the canals out of privately owned upland. Thus, the attorney opined that the canal bottom is privately owned. Some question may exist as to the delineation of the historic mean high water line, especially regarding its location relative to the waterward edge of the red mangrove fringe, which DEP would consider part of the historic natural waterbody. There may be some question specifically concerning title to the bottom of the northernmost canal where it joins Deep Lagoon. However, the proof required of Applicant for present purposes is considerably short of the proof required to prove title, and the attorney's testimony, absent proof to the contrary, is sufficient to demonstrate the requisite ownership interest to seek the exemption and permit that are the subject of these cases. From north to south, Deep Lagoon Marina comprises the north canal, which is about 1200 feet long and bounded on the north by a red mangrove fringe 10-20 feet wide; a peninsula; the central canal, which is also known as the central or main basin and is roughly the same length as the north canal; a shorter peninsula; and the south canal, which is about half the length of the central canal and turns to the southeast at a 45-degree angle from the midway point of the central canal. The three canals are dead-end canals, terminating at their eastern ends a short distance from MacGregor Boulevard. Manatees and Boating The Caloosahatchee River is critical habitat for the endangered West Indian manatee. Up to 500 manatees use the river during the winter. When, during the winter, the water cools, the animals congregate in waters warmed by the thermal discharge from a power plant about 13 miles upstream of Deep Lagoon. When, during the winter, the water warms, the manatees swim downstream, past and into Deep Lagoon searching for food. Manatees frequently visit Deep Lagoon. It is one of the few places between the power plant and the Gulf where manatees can find a quiet place, relatively free of human disturbance, to rest and feed. Within Deep Lagoon, the Iona Drainage District ditch runs parallel to the north canal, separated from the canal by the previously described mangrove fringe. The Iona Drainage District ditch empties into Deep Lagoon just north of the mouth of the north canal. Manatees frequently visit the ditch because it is a seasonal source of freshwater, which the manatees drink. Manatees visit the north canal due to its moderate depths and proximity to the freshwater outfalls of the Iona Drainage District ditch. Manatee mortality from watercraft is extremely high in the immediate vicinity of Deep Lagoon, and the mortality rate has increased in recent years. The rate of manatee deaths from collisions with watercraft has increased with the popularity of motorboating. Boat registrations in Lee County rose from 13,000 in 1974 to 36,000 in 1997. The potential for mitigation offered by the enactment of speed zones has been undermined by the fact that nearly half of the boaters fail to comply with the speed limits. Water Quality The Caloosahatchee River is laden with sediments, partly due to intermittent discharges from Lake Okeechobee. Seagrass in the riverbottom cannot grow in water much deeper than four feet. Some seagrass grows at the mouth of Deep Lagoon, but little seagrass extends into the lagoon itself. The water quality in the canals is very poor for dissolved oxygen and copper. Applicant stipulated that the water quality in Deep Lagoon violates state standards for dissolved oxygen, copper, and coliform bacteria. In 1997, the canals violated water quality standards for dissolved oxygen nearly each time sampled during the wet season and one-third of the times sampled during the dry season. The dissolved oxygen levels violated even the lower standards for Class IV agricultural waters two-thirds of the times sampled during the wet season. In 1997, the canals violated water quality standards for copper in the water column each time sampled during the wet season and two-thirds of the times sampled during the dry season. During three of the dry season samplings, copper levels were 20 to 30 times lawful limits. The three lowest wet season copper levels were double lawful limits. Copper is a heavy metal that is toxic to a wide range of marine organisms. Copper is applied to boat hulls to prevent marine life from attaching to the hulls. In 1997, the canals violated water quality standards for total coliform bacteria (for any single reading) three of the 60 times sampled during the dry season and one of the 56 times sampled during the wet season. The canals violated the more relaxed, 20-percent standard (which is violated only if 20 percent of the readings exceed it) during the wet season, but not during the dry season. In 1997, the canals violated water quality standards for lead in the water column in one sample (by 25 percent) out of 36, but did not violate water quality standards for oil and grease or fecal coliform bacteria. Results of testing for mercury in the water column (as opposed to sediments) are not contained in the record. As compared to 1987, the water quality in the canals has improved in all but one important respect. In 1987, the water column readings for copper were five to six times higher than the highest 1997 reading. In 1987, the total coliform bacteria were too numerous to count because the colonies had grown together in the sample. However, comparing the April 1987 data with the May 1997 data for the same approximate times of day and the same locations, the dissolved oxygen levels in the three canals have declined dramatically in the last 10 years. Ten years ago, in a one-day sampling period, there were no reported violations; ten years later, in a one-day sampling period, there were four violations. Even worse, the amount of dissolved oxygen in the water during daylight hours has been halved in the last 10 years with a smaller decrease during nighttime hours. Original Permit There are three types of permits relevant to these cases. The first is a dredge and fill permit (sometimes referred to in the record as a wetland resource permit or water resource permit)(DAF permit). The second is a surface water management (sometimes referred to in the record as a management and storage of surface water (MSSW) permit or stormwater management permit)(SWM permit). The third is an environmental resource permit (ERP). Several years ago, responding to a mandate from the Legislature, DEP and the water management districts consolidated DAF permits, which historically were issued by DEP, and SWM permits, which historically were issued by the water management districts, into ERPs. At the time of this change, DEP adopted, within the jurisdictional areas of each water management district, certain of the rules of each district. In 1988, DEP issued a DAF permit to Applicant's predecessor in title for additional wet slips (as modified, the Original Permit). Due partly to the likelihood of the replacement of some older, smaller slips with larger slips, there is some uncertainty as to the precise number of wet slips that Applicant would be able to construct under the Original Permit. However, Applicant would be able to construct approximately 89-113 new wet slips, with an additional 14,440 square feet of overwater decking, so as to raise its marina capacity to 150-174 wet slips. Applicant also plans to construct 227 dry slips, so as to raise its marina capacity to 427 dry slips, and add 115,000 square feet of buildings, including a restaurant. In general, the Original Permit authorizes Applicant to renovate and expand an existing marina from 61 wet slips to 174 wet slips by: excavating 0.358 ac of uplands to create a flushing canal, installing 375 linear feet of seawall along the sides of the flushing canal, excavating 2.43 ac of submerged bottom to remove contaminated sediments, backfilling 2.41 acres of the dredged area (the main basin and south canal to -7 ft. MLW and the north canal to -6 ft. MLW) with clean sand, renovating the existing 61 slips, and constructing an additional 14,440 square feet of overwater decking for 113 new slips, providing after-the-fact authorization for construction of 2 finger piers, creating a 400 sq. ft. mangrove fringe, constructing 180 linear feet of seawall in the vicinity of the mangrove fringe, and relocating and upgrading fueling facilities. The record contains various references to "MLW" or "mean low water," "MHW" or "mean high water," and "NGVD" or "National Geodetic Vertical Datum." The drawings attached to the Original Permit state that MHW equals 0.96 feet NGVD and MLW equals about 0.40 feet NGVD. The Original Permit authorizes activities to proceed in three phases: First, the majority of the water quality improvement measures will be implemented as required in Specific Condition 5. Second, the over water docking structures will be constructed and the fueling facilities will be upgraded and relocated as required in Specific Conditions 6 and 7. Third, the new slips will be occupied in accordance with the phasing plan in Specific Condition 9. Specific Condition 5 imposes several requirements designed "to ensure a net improvement in water quality." Among these requirements is that Applicant must obtain the ERP that is the subject of DOAH Case No. 98-5409 (New Permit). Specific Condition 5 states: In order to ensure a net improvement to water quality within the basin, the construction of any new docking structures or installation of any new pilings shall not occur until the below-listed conditions (A-K) have been met. . . . A baseline water quality study . . .. A stormwater treatment system providing treatment meeting the specifications of Florida Administrative Code 40E-4 for all discharges into the basins from the project site shall be constructed. . . . The boat wash area shall be re-designed and constructed as shown on Sheets 23 and 23A. All water in the washdown area shall drain into the catch basin of the wastewater treatment system shown on Sheet 23. The water passing through the wastewater treatment system shall drain to the stormwater management system which was previously approved by the South Florida Water Management District. The filters of the wastewater treatment system shall be maintained in functional condition. Material cleaned from the filter shall be disposed of in receptacles maintained specifically for that purpose and taken to a sanitary landfill. This system shall be maintained in functional condition for the life of the facility. [As cited, this subparagraph contains modifications stated in a letter dated March 26, 1997, from DEP to Applicant's predecessor in interest.] Contaminated sediments shall be dredged from the areas shown on Sheets 5 and 7 of 23. A closed-bucket clam shell dredge shall be used. The north canal shall be dredged to at least -9.9 feet MLW and backfilled with clean sand to -6 feet MLW. The [main] basin shall be dredged to at least -7.3 feet MLW and backfilled with clean sand to -7 feet MLW. The south canal shall be dredged to at least -10.5 feet MLW and backfilled with clean sand to at least -7.0 feet MLW. Backfilling shall be completed within 120 days of completion of dredging. . . . The sediments shall be placed directly in sealed trucks, and removed to a self-contained upland disposal site which does not have a point of discharge to waters of the state. A channel, 260 ft. long, 60 ft. wide, with a bottom elevation of -4.5 ft. MLW shall be excavated between the north canal and the main basin to improve flushing. * * * K. Upon completion [of] conditions A-J above, renovation of the existing 61 wet slips and construction of the 113 additional wet slips may proceed with the understanding that construction of all 113 additional slips is at the risk of the permittee and that if the success criteria in the monitoring and occupancy program are not met, removal of all or part of the additional slips may be required by the Department. Specific Condition 8 addresses the phasing of occupancy of the wet slips. Specific Condition 8 provides: Occupancy of the additional 113 wet slips shall occur in two phases, described below. Permanent occupancy of the slips shall require [DEP] approval, contingent upon the water quality monitoring program demonstrating a statistically significant (Specific Condition 9) net improvement for those parameters which did not meet State Water Quality Standards in the baseline study. The permittee agrees that if [DEP] determines that net improvement has not occurred, or if violations of other standards occur, and if the corrective measures described in Specific Condition 10 are not successful, all of the additional slips occupied at that time shall be removed. . . . Phase I--Upon completion of the baseline water quality study and the work specified in Specific Condition No. 5, the existing 61 slips and an additional 56 slips, totalling 117 slips, may be occupied. . . . If at the end of one year of monitoring, the data generated from the water quality monitoring program shows a statistically significant improvement over baseline conditions, for those parameters in violation of State Water Quality Standards, and no violations of additional parameters, . . . the new 56 slips which were occupied shall be considered permanent. Phase II--Upon written notification from [DEP] that Phase I was successful, the remaining 57 additional slips may be occupied. Water and sediment quality monitoring shall continue for two years after the occupancy of 140 of the 174 slips. If a statistically significant net improvement to water quality over baseline conditions for those parameters in violation of State Water Quality Standards [sic] and no violation of additional parameters is shown by the monitoring data, and confirmed by [DEP] in writing, the additional slips shall be considered permanent. * * * Specific Condition 11 adds: Implementation of the slip phasing plan described in Specific Condition 8 shall be contingent on compliance of boaters with existing speed zones in the Caloosahatchee River and trends in manatee and [sic] mortality. . . . Approval of additional slips will depend upon manatee mortality trends and boater compliance with speed zones in the Caloosahatchee River and additional slips may not be recommended. . . . Based on the results of the evaluations of Phases I and II, [DEP] may require that slips be removed to adequately protect manatees. Specific Condition 12 requires the construction of a 400 square-foot intertidal area for the planting of mangroves to replace the mangroves lost in the construction of the flushing channel. Specific Condition 14 prohibits liveaboards at the marina. Specific Condition 15 adds various manatee-protection provisions. Plan Views C and D, which are part of the Original Permit, depict submerged bottom elevations for the north and central canals, as well as from the south canal at its intersection with the central canal. Dated August 30, 1995, these "existing" bottom elevations across the mouth of the north canal are about -7, -8, and -4 feet (presumably MLW; see second note to Plan View B). The western two-thirds of the north canal passes over bottoms of about -6 feet MLW. Proceeding east, the bottom deepens to -7 to -9 feet MLW before it tapers up to -7, -6, and finally -3 feet MLW at the head; and the eastern third of the north canal passes over bottoms of about -7 feet MLW that tapers up to -6 feet and -3 feet MLW. The submerged bottom at the mouth of the central canal is about -8 to -9 feet MLW. The bottom drops to -6 to -10 feet MLW at the intersection with the south canal. Proceeding east, the bottom deepens slightly as it reaches the head, where it is -8 feet MLW. The submerged bottom of the south canal runs from -9 feet MLW at the intersection with the central canal and runs about 0.5 feet deeper at the head. Petitioner and others challenged the issuance of the Original Permit in 1988. The permit challengers appealed a final order granting the Original Permit and certifying, under the federal Clean Water Act, that state water quality standards were met. DEP premised its certification on the concept that water quality standards encompassed a net improvement in water quality of the poorly flushed canals. In Sheridan v. Deep Lagoon Marina, 576 So. 2d 771, 772 (Fla. 1st DCA 1991), the court, relying on the above-described 1987 water quality data, noted the "very poor water quality" of Deep Lagoon, as reflected in part by the presence of oil and grease 20 times the Class III standard, copper 13 times the standard, lead 20 times the standard, mercury 1000 times the standard, and coliform bacteria "too numerous to count." However, the court affirmed the issuance of the Original Permit under the statutory authorization of a permit where ambient water quality does not meet applicable standards, but the activity will provide a net improvement to the waters. On the certification issue, though, the court reversed and remanded. The court held that the hearing officer erroneously excluded evidence on DEP's certification of the activity as in compliance the federal Clean Water Act. Following remand, DEP issued a final order issuing the Original Permit. On the certification issue, the final order revoked the earlier certification of compliance and, citing 33 United States Code Section 1341 as authority, waived certification as a precondition to federal permitting. Maintenance Dredging: DOAH Case No. 98-3901 Background The contentions of Petitioner and Intervenor as to maintenance dredging are: the proposed dredging exceeded what was necessary to restore the canals to original design specifications or original configurations; the proposed dredging exceeded the maximum depth allowable for maintenance dredging of canals; the work was not conducted in compliance with Section 370.12(2)(d), Florida Statutes; the spoil was not deposited on a self-contained upland site to prevent the escape of the spoil into waters of the state; and the dredge contractor did not use control devices and best management practices for erosion and sediment control to prevent turbidity, dredged material, and toxic or deleterious substances from discharging into adjacent waters during maintenance dredging. On March 3, 1998, Applicant's engineering consultant submitted drawings to DEP with notification that Applicant intended to "maintenance dredge the internal canals of Deep Lagoon Marina," in conformity with Rule 62-312.050(e), Florida Administrative Code. The letter describes the proposed dredging as mechanical "with no discharge back into Waters of the State." The letter assures that Applicant's contractor will use turbidity curtains "around the dredging and spoil unloading operation" and advises that the contractor will unload the spoil "to the north peninsula upland area." The letter states that the dredging "will be to the design depth/existing canal center line depth of -7 NGVD," which was established by the Original Permit, and will be "done in conjunction with the required dredging under [Original Permit] Condition 5(D)." The consultant attached to the March 3 letter several drawings showing the dredging of all three canals. For each canal, the drawings divide the dredging into two areas. For 1.82 acres, the contractor would dredge contaminated materials from the dead-ends of the three canals (for the south canal, a portion running from the head along the northeast half of the canal) and then replace these materials with clean backfill material. This information is for background only, as the Original Permit authorized this contaminant dredging. For 4.84 acres, which run through the remainder of the three canals, the contractor would maintenance dredge in accordance with the cross-sections provided with the letter. The cross-sections for the north canal reveal relatively extensive dredging beyond the vegetation lines on both sides of the canal bottom. The dredging would extend up to, but not beyond, the edges of the prop roots of the mangroves on both sides of the canal bottom. The contours reveal variable, proposed slope profiles for the submerged sides of the canals, but the dredging would substantially steepen the submerged slopes of the north canal. It is difficult to estimate from the cross-sections the average depth and width to be dredged from the north canal, but it appears that the cross-sections proposed the removal of substantial spoil (an average of 4-6 feet) from areas from 20-40 feet from each side of the deepest point in the north canal. The dredging would alter the two most affected cross-sections, which are just inside the mouth of the north canal, by widening the deepest part of the canal bottom by 85 feet--from about 15 feet to about 100 feet. The drawings proposed much smaller alterations to the bottoms of the central and south canals: typically, spoil about 2 feet deep and 20 feet wide. All but one of the cross-sections revealed that spoil would be dredged only from one side of the deepest point. Additionally, the dredging in these canals would not involve any submerged vegetation; all but one of the canal sides was lined by existing seawalls. By letter dated March 13, 1998, DEP stated that it had determined that, pursuant to Rule 40E-4.051(2)(a), Florida Administrative Code, the proposed activity was exempt from the requirement that the Applicant obtain an ERP. The letter warns that, pursuant to Chapter 62-302, Florida Administrative Code, the construction and operation of the project must not cause water quality violations. The letter adds that DEP may revoke its determination of exemption if the "basis for the exemption is determined to be materially incorrect, or if the installation results in water quality violations." The letter provides a point of entry for persons whose substantial interests are affected by DEP's determination. Following receipt of DEP's letter acknowledging the exemption, Applicant's contractor proceeded to maintenance dredge the three canals. The dredging of the north canal took eight weeks. Applicant's contractor also performed the contaminant dredging and clean backfilling authorized by the Original Permit. As indicated in the March 3 letter and permitted in the Original Permit, the contaminant dredging took place at the dead-end heads of the north and central canals and along the northeast half of a slightly longer section of the south canal, starting from its dead-end head. In maintenance dredging the canals, Applicant's contractor did not exceed the specifications regarding depth and width stated in its March 3 letter. To the contrary, the contractor sometimes dredged slightly narrower or slightly shallower profiles than stated in the March 3 letter. For example, the contractor dredged the north canal to -6 feet NGVD (or -5.6 feet MLW), rather than -7 feet NGVD, as shown in the March 3 letter. The Depths, Widths, and Lengths of Dredging The March 3 letter asserts that -7 feet NGVD is the permitted elevation of the canal bottoms, pursuant to the Original Permit. This is incorrect in two respects. First, the assertion in the March 3 letter of a -7 foot permitted bottom elevation is incorrect for all but the relatively small part of each canal that DEP has determined is contaminated. The Original Permit specifies design elevations for canal bottoms only in the contaminated area within each canal. Nothing in the Original Permit permits bottom elevations for any portion of the bottoms of the three canals outside of these three contaminated areas. Second, the assertion in the March 3 letter of a -7 foot permitted bottom elevation is incorrect, even for the contaminated areas. The March 3 letter states -7 feet NGVD, but the Original Permit specifies bottom elevations, for contaminated areas only, of -7 feet MLW in the south and central canals and -6 feet MLW in the north canal. Thus, due to the differences between NGVD and MLW, the March 3 letter proposes dredging that would deepen the south and central canals by about five inches deeper than the depth permitted in the Original Permit and the north canal by one foot five inches deeper than the depth permitted in the Original Permit. Moreover, nothing in the record clearly establishes all aspects of the original design specifications of the three canals, whether permitted or not, or even all aspects of their original dredged configurations, if not permitted. There is no dispute concerning one aspect of the dredged configuration of the three canals: their lengths. Although there may be some dispute as to the original mean high water line near the mouths of the north and central canals, the original length of the canals is evident from the uplands that presently define them. As to the depth of the canals, although direct evidence is slight, Applicant has sufficiently proved indirectly the depths of the mouths of the canals pursuant to original design specifications or, if not designed, original configurations. The proved bottom elevations are -7 feet NGVD for each canal. Applicant proved these depths based on the prevailing elevations in Deep Lagoon in the vicinity of the mouths of the north and central canal and bottom elevations in areas of Deep Lagoon that are not prone to sedimentation. Additional proof of the bottom elevation of -7 feet NGVD at the mouths of the canals is present in the slightly higher permitted bottom elevations at the dead- ends of the north and central canals and landward portion of the south canal. There is some problem, though, with the proof of the depth of the canal bottoms between their mouths and heads (or, for the south canal, its landward portion of known contamination). Although the problem of the depth of the canals between their heads and mouths might be resolved by inferring a constant bottom elevation change from the deeper mouth to the shallower head, an unresolveable issue remains: the width of this maximum depth. As already noted, without deepening the deepest part of either cross-section, the contractor widened the deepest points along two cross-sections by 85 feet each. In terms of navigability and environmental impact, the width of the maximum depth of a canal is as important as its maximum depth. As to the width of the lowest bottom elevations of the canals, Applicant has produced no proof of original design specifications or, if not designed, original configurations. Nor has Applicant produced indirect proof of historic widths. Nothing in the record supports an inference that Applicant's predecessor in interest originally dredged the canal bottoms as wide as Applicant "maintenance" dredged them under the claimed exemption. Nothing in the record supports an inference that Applicant's predecessor geometrically dredged the canals so that their sides were perpendicular to their bottoms. Nothing in the record describes a sedimentation problem that might have narrowed the canals by such an extent that the dredging of the present widths, especially in the north canal, would be restorative. Nothing in the record even suggests that the original motive in dredging was navigability, which might have yielded relatively wide canal bottoms, versus upland fill, which would yield canal bottoms as wide as needed, not for navigability, but for uplands- creation. After consideration of all the evidence, no evidence supports a finding that the proposed dredging profiles, in terms of the widening of the areas of lowest elevation in each canal bottom, bear any resemblance whatsoever to the original canal profiles, as originally (or at any later point) designed or, if not designed, as originally (or at any later point) configured. It is at least as likely as not that this is the first time that these canal bottoms, especially the north canal bottom, have ever been so wide at any bottom elevation approaching -7 feet NGVD. There is simply no notion of restoration or maintenance in the dredging that produced these new bottom profiles for these three canals. Transforming MLW to NGVD, -5 feet MLW is -4.6 feet NGVD. All proposed and actual maintenance dredging in the three canals dredged the canal bottoms to elevations lower than -5 feet MLW (or -4.6 feet NGVD), despite the absence of any previous permit for construction or maintenance of the canal from the Trustees of the Internal Improvement Trust Fund or the United States Army Corps of Engineers. Impact of Dredging on Manatees and Spoil Containment Prior to dredging, Applicant deployed turbidity curtains around the mouths of the two canals that discharge directly into Deep Lagoon. In this case, the turbidity curtains performed two functions. They contained turbidity and resuspended bottom contaminants within the mixing zone behind (or landward of) the curtains, and they excluded manatees from the dangerous area behind the curtains where the dredging was taking place. Petitioner and Intervenor object to the use of the turbidity curtains on two general grounds. First, they claim that the curtains failed to contain turbidity and resuspended contaminants from escaping the mixing zone. Second, they claim that the curtains adversely affected manatees. As executed, the maintenance dredging did not result in the release of turbidity or resuspended contaminants outside of the mixing zone due to the use of turbidity curtains. Applicant's contractor ensured that the curtains extended from the water surface to the canal bottom and sufficiently on the sides to prevent the escape of turbidity or resuspended contaminants. Although the March 3 letter did not indicate where the contractor would deploy the turbidity curtains, the important point, in retrospect, is that the contractor properly deployed the curtains. There is some question whether turbidity or resuspended contaminants flowed across the mangrove fringe and into the Iona Drainage District ditch. Applicant's witness testified that water flows across the fringe only during the highest three or four tides per month. Petitioner and Intervenor's witness testified that water flows across the fringe as often as twice per day. The actual frequency is likely somewhere between these two extremes, but, regardless of the frequency, there is insufficient evidence to find that any turbidity or resuspended contaminants flowed from the north canal into the Iona Drainage District ditch. Nor did the deployment of the turbidity curtains injure, harm, possess, annoy, molest, harass, or disturb any manatees. Applicant and its contractor carefully checked each canal for manatees before raising the turbidity curtains at the mouth of each canal, so as not to trap any manatees in the area behind the curtains. By ensuring that the curtains extended to the canal bottom and extended fully from side to side, they ensured that the curtains excluded manatees during the dredging. There is no evidence that a manatee could have entered the north canal from the Iona Drainage District ditch by crossing the red mangrove fringe; any breaks in the fringe were obstructed by prop roots that prevented even a kayaker from crossing the fringe without portaging. Applicant and its contractor checked for manatees during dredging operations. Petitioner and Intervenor contend that the mere presence of the turbidity curtains in an area frequented by manatees adversely affected the animals. However, this argument elevates a speculative concern with a manatee's response to encountering an obstruction in its normal path over the practical purpose of curtains in physically obstructing the animal so as to prevent it from entering the dangerous area in which the dredge is operating, as well as the unhealthy area of turbidity and resuspended contaminants in the mixing zone. Under the circumstances, the use of the turbidity curtains to obstruct the manatees from visiting the dredging site or mixing zone did not adversely affect the manatees. In general, there is no evidence of any actual injury or harm to any manatees in the course of the dredging or the preparation for the dredging, including the deployment of the turbidity curtains. Petitioner and Intervenor offered evidence that maintenance dredging would result in more and larger boats and deterioration of water quality, which would both injure the manatees. However, as noted in the conclusions of law, the Administrative Law Judge excluded from DOAH Case No. 98-3901 such evidence concerning long-term impacts upon the manatees following the dredging. As for spoil containment, Applicant's contractor segregated the contaminated spoil from noncontaminated spoil by placing the contaminated spoil in a lined pit in the uplands. The contractor also brought onto the uplands clean fill mined from a sand quarry for backfilling into the dredged contaminated areas. There is evidence of the clean fill subsiding from its upland storage site and entering the canal waters in the mixing zone. Partly, this occurred during the loading of the barge, which transported the clean fill to the dead-end heads of the canals where the fill was placed over the newly dredged bottoms. The fill escaped into the water at a location about 100 feet long along the north seawall of the central canal, but the evidence does not establish whether this location was within the contaminated area at the head of the canal or whether the maintenance or contaminant dredging had already taken place. If the fill subsided into the water inside of the contaminated head of the south canal and the subsidence occurred prior to the contaminant dredging, the subsidence was harmless because the contractor would remove the fill during the dredging. If the fill subsided into the water inside the contaminated head of the south canal and the subsidence occurred after the contaminant dredging, the subsidence was harmless because the contractor intended to add the fill at this location. If the fill subsided into the water outside of the contaminated head of the south canal and the subsidence occurred prior to maintenance dredging, the subsidence was harmless because the contractor would remove the fill during the dredging. If the fill subsided into the water outside the contaminated head of the south canal and the subsidence occurred after the maintenance dredging, the subsidence was harmless because it restored the canal bottom to a higher elevation following the dredging to an excessively low elevation. The subsidence of the clean fill into the water along the north side of the central canal is the only material that entered the water from the uplands during the dredging. Specifically, there is no evidence of dredged spoil entering the water from the uplands during or after the dredging. There is also no evidence that the maintenance dredging significantly impacted previously undisturbed natural areas. There is no evidence of such areas within the vicinity of Deep Lagoon Marina. New Permit: DOAH Case No. 98-5409 New Permit Seeking to satisfy certain of the requirements of Original Permit Specific Condition 5, Applicant filed with DEP, on December 10, 1997, an application for an ERP and water quality certification to construct a surface water management system to serve 15.4 acres of its 24-acre marina. Prior to its reformulation as an ERP, the New Permit sought by Applicant would have been a SWM permit. The application notes that the general upland elevation is 5 feet NGVD and that stormwater runoff presently sheetflows directly to adjacent waterways without any treatment. During the application process, Applicant's engineer Christopher Wright, submitted a letter dated February 27, 1998, to Jack Myers, who is a Professional Engineer II for DEP. In response to a request from DEP for a "written procedure . . . to assure the proper functioning of the proposed . . . system," the letter states: Since the system is not designed as a retention system and does not rely upon infiltration to operate properly[,] operation and maintenance is minimal. Items that will need regular maintenance are limited to removal of silt and debris from the bottom of the drainage structures and the bleed down orifice of the control structure. A maintenance and inspection schedule has been included in this re-submittal as part of Exhibit 14. In relevant part, Exhibit 14 consists of a document provided Mr. Wright from the manufacturer of the components of the surface water management system. The document states that the manufacturer "recommends that the landowner use this schedule for periodic system maintenance . . .." The document lists 16 sediment-control items, but it is unclear whether all of them are incorporated into the proposed system. Four items, including sediment basins, require inspections quarterly or after "large storm events" and maintenance consisting of the removal of sediment; the "water quality inlet" requires inspections quarterly and maintenance consisting of "pump[ing] or vacuum[ing]"; the "maximizer settling chamber" requires inspection biannually and maintenance consisting of "vacuum[ing] or inject[ing] water, suspend silt and pump chamber"; and the "chamber" requires inspection annually and the same maintenance as the maximizer settling chamber. The proposed system includes the water quality inlet and one of the two types of chambers. By Notice of Intent to Issue dated November 5, 1998, DEP provided notice of its intent to issue the New Permit and certification of compliance with state water quality standards, pursuant to Section 401 of the Clean Water Act, 33 United States Code Section 1341. On February 6, 1999, DEP revised the notice of intent by withdrawing its certification of state water quality compliance. As it did with the Original Permit, DEP again waived state water quality certification. This waiver is consistent with a letter dated February 2, 1998, in which then-DEP Secretary Virginia Wetherell announced that DEP would waive state water quality certification for all activities in which the agency issues an ERP based on the "net improvement" provisions of Section 373.414(1)(b), Florida Statutes. The notices of intent (collectively, NOI) recite the recent permitting history of the marina. This history includes the Original Permit, a since-expired MSSW permit issued in 1988 by SFWMD, and then-pending requests--apparently all since granted--to revise the Original Permit by replacing the flushing canal with culverts, relocating a travel lift from the main canal to the north canal, and adding liveaboards to the marina. (Although mentioned below, these revisions, in and of themselves, do not determine the outcome of DOAH Case No. 98-5409.) Reviewing the proposed development for the site, the NOI states that the northerly part of the project would contain an indoor dry boat storage barn, a marina service operation consisting of a ship store and miscellaneous buildings, a harbor master building, an upgraded fueling facility, a parts and service center, a restaurant, retail and commercial facilities, and paved parking areas. The southerly part of the project would contain a new indoor dry boat storage barn, a boat dealership building, and paved parking areas in place of the existing buildings. The NOI states that the proposed water quality treatment system would comprise dry detention systems of several underground vaults with an overall capacity based on the total impervious area, including roofs, receiving 2.5 inches of rain times the percentage of imperviousness. Given the relatively high imperviousness of the finished development, this recommended order considers the percentage of imperviousness to be 100, but ignores the extent to which the post-development pervious surfaces would absorb any rainfall. For storms producing up to 2.5 inches of runoff, the proposed surface water management system, of which the underground vaults are a part, would trap the runoff and provide treatment, as sufficiently sized contaminants settled into the bottom of the vaults. Because the vaults have unenclosed bottoms, the proposed system would provide incidental additional treatment by allowing stormwater to percolate through the ground and into the water table. However, the system is essentially a dry detention system, and volumetric calculations of system capacity properly ignored the incidental treatment available through percolation into the water table. The New Permit notes that the wet season water table is 1.2 feet NGVD, and the bottom of the dry detention system is 2.5 feet NGVD. This relatively thin layer of soil probably explains why DEP's volumetric calculations ignored the treatment potential offered by percolation. The relatively high water table raises the possibility, especially if Applicant does not frequently remove the settled contaminants, that the proposed system could cause groundwater contamination after the thin layer of soil is saturated with contaminants. In any event, the system is not designed for the elimination of the settled contaminants through percolation. The treatment system for the boat wash areas would be self-contained, loop-recycle systems that would permit the separation of oil and free-settling solids prior to reuse. However, the NOI warns that, "during heavy storm events"-- probably again referring to more than 2.5 inches of runoff--the loop-recycle systems would release untreated water to one of the underground vaults, which would, in turn, release the untreated water into the canals. Due to the location of the boat wash areas, the receiving waters would probably be the north canal. As reflected in the drawings and the testimony of Mr. Wright, the surface water management system would discharge at three points: two in the north canal and one in the south canal. (Vol. I, p. 206; future references to the Transcript shall cite only the volume and page as, for example, Vol. I, p. 206). 67. The NOI concludes that Applicant has provided affirmative reasonable assurance that the construction and operation of the activity, considering the direct, secondary and cumulative impacts, will comply with the provisions of Part IV of Chapter 373, F.S., and the rules adopted thereunder, including the Conditions for Issuance or Additional Conditions for Issuance of an environmental resource permit, pursuant to Part IV of Chapter 373, F.S., Chapter 62-330, and Sections SFWMD--40E-4.301 and 40E-4.302, F.A.C. The construction and operation of the activity will not result in violations of water quality standards and will not degrade ambient water quality in Outstanding Florida Waters pursuant to Section 62-4.242, F.A.C. The Applicant has also demonstrated that the construction of the activity, including a consideration of the direct, secondary, and cumulative impacts, is clearly in the public interest, pursuant to Section 373.414(1)(a), F.S. However, the design capacity of the proposed surface water management system raises serious questions concerning the water quality of the discharges into the canals. Mr. Wright initially testified that the surface water management system would be over-taxed by "an extreme storm event, probably a 25- year storm event . . .." (Vol. I, pp. 208-09). The record contains no evidence of the frequency of the storm event that produces 2.5 inches of runoff for the relatively impervious post- development uplands; the record contains no evidence even of the frequency of the storm event that produces 2.5 inches of rainfall. According to Mr. Wright, the 25-year storm would typically produce 8-10 inches of rain. (Vol. I, pp. 223 and 233). As already noted, the relatively large area of imperviousness following upland development and the relative imperviousness of the upland soils present at the site suggest that the runoff will be a relatively large percentage of the rainfall produced by any given storm event. It thus appears that the design capacity of the system is for a storm substantially smaller and substantially more frequent than the 25-year storm. Attached to the NOI is a draft of the New Permit, which contains numerous specific conditions and conforms in all respects with the NOI. Omitting any mention of SFWMD's Basis of Review, the New Permit addresses, among other things, the operation, inspection, and maintenance of the components of the proposed system. As set forth in the testimony of Michael Bateman, who is a Professional Engineer III and statewide stormwater coordinator for DEP, the surface water management system's operation depends on periodic pumping of the "thick, fine sediment," which appears to be a "cross between mud and sand" and will be laden with oil, grease, metals, and other contaminants. (Vol. II, p. 66). However, contrary to Mr. Bateman's assurance that the New Permit requires the periodic pumping or removal of contaminants that have precipitated out of the runoff in the dry detention system and dropped to the bottom sediment (Vol. II, p. 20), neither the NOI nor the New Permit requires, in clear and enforceable language, the periodic removal of settled solids from the underground vaults or their manner of disposal. New Permit Specific Condition 8 requires that Applicant maintain the boat wash area in "functioning condition," although specific inspection and maintenance requirements are omitted from the New Permit. New Permit Specific Condition 7 requires that Applicant "inspect and clean" all stormwater inlets "as necessary, at least once a month and after all large storm events," although the New Permit fails to specify that cleaning shall be by either pumping or vacuuming. By contrast to the marginally adequate inspection and maintenance provisions applicable to the boat wash area (inspections are required in Specific Condition 6, cited below) and stormwater inlets, the New Permit completely fails to specify enforceable inspection and maintenance requirements for the underground vaults. New Permit Specific Condition 6 addresses the operation of the vault as follows: Upon completion of the construction of the stormwater collection and underground vault (Infiltrator) systems and on an annual basis thereafter by September 30 of each year, the Permittee shall submit reports to the Department as to the storage/treatment volume adequacy of the permitted system. The reports shall also include, but not be limited to, the condition of stormwater inlets and control structures as to silt and debris removal and the condition of the inlet wire mesh screens to function properly. The boat wash down areas shall be inspected for proper operation, i.e., no signs of wash water overflows from the containment area, condition of the containment area curbing, etc. Such reports shall include proposal of technique and schedule for the maintenance and/or repair of any deficiencies noted and shall be signed and sealed by a Florida registered Professional Engineer. A report of compliance with the aforementioned proposal shall be submitted by the Professional Engineer to the Department upon completion of the proposed work which shall be accomplished within three months of the initial report for each year. New Permit Specific Condition 6 requires annual reports concerning the sufficiency of the capacity of the underground vaults (first sentence), annual reports of the status of silt- and debris-removal from the inlets and control structures and the condition of the inlet wire mesh screens (second sentence), inspection at no stated intervals of the boat wash area (third sentence), and annual reports with suggestions of maintenance schedules and repairs for the items mentioned in the first two sentences (fourth sentence). New Permit Specific Condition 6 promises only the preparation of a maintenance schedule at some point in the future. Failing to supply an enforceable inspection and maintenance program, Specific Condition 6 indicates that Applicant shall consider in the future techniques and scheduling of maintenance, presumably based on the report concerning system capacity. Such a requirement may or may not impose upon Applicant an enforceable obligation to adopt an enforceable inspection and maintenance program in the future, but it does not do so now. There is no reason why the New Permit should not impose upon Applicant an initial, enforceable inspection and maintenance program incorporating, for example, the clear and enforceable requirements that Applicant inspect all of the underground vaults no less frequently that once (or twice, if this is the applicable recommendation of the manufacturer) annually and, at clearly specified intervals, remove the sediments by resuspending the sediments in the water, pumping out the water, and disposing of the effluent and sediments so they do not reenter waters of the state. Although the record does not disclose such requirements, Applicant could possibly find manufacturer's recommendations for the boat wash components and incorporate them into an enforceable inspection and maintenance program more detailed than that contained in Specific Condition 8. However, for the reasons noted below, water quality considerations require a substantial strengthening of such a program beyond what is set forth in this paragraph as otherwise acceptable. At present, the bottom line on inspection and maintenance is simple: the New Permit does not even incorporate by reference the manufacturer's recommended inspection and maintenance schedule, which Mr. Wright provided to Mr. Myers. Nor was this shortcoming of the New Permit in its treatment of inspection and maintenance necessarily missed by Mr. Wright. He testified that he submitted to DEP the manufacturer's maintenance program (Vol. I, p. 205), but when asked, on direct, if the "permit in any way incorporate[s] the commitment in your application to this maintenance?" Mr. Wright candidly replied, "That I don't know." (Vol. I, p. 206). Satisfaction of Basis of Review Section 5 Basis of Review Section 5--specifically Section 5.2.1(a)--imposes the "volumetric" requirement of 2.5 inches times the percentage of imperviousness, as discussed above and in the conclusions of law. Petitioner does not dispute Applicant's compliance with this volumetric requirement, and the record amply demonstrates such compliance. Applicability of Basis of Review Section 4 The main issues in this case are whether the environmental and water quality requirements of Basis of Review Section 4 apply to the direct, secondary, and cumulative impacts of the proposed activity. Because the record lacks any indication of other relevant pending or vested permits, without which, as noted in the conclusions of law, one cannot assess cumulative impacts, the remainder of the findings of fact will not discuss cumulative impacts, although, to some extent, increased boating pressure constitutes a secondary impact and a cumulative impact. Without regard to the differences between direct and secondary impacts, DEP has taken the position in this case that it could lawfully issue the New Permit upon satisfaction of the volumetric requirements of Basis of Review Section 5 and without consideration of the requirements of Basis of Review Section 4. In large part, DEP's witnesses justify this position by reliance on the historic differences between DAF permits and SWM permits and the fact that the New Permit is a former-SWM ERP. As discussed in detail in the conclusions of law, the Basis of Review imposes different requirements upon former-DAF and former-SWM ERPs, although the Basis of Review does not refer to DAF or SWM permits by their former names. The identifying language used in the Basis of Review for former-DAF ERPs is "regulated activity" "located in, on, or over surface waters or wetlands." References to "regulated activity" without the qualifying clause indicate that the following requirement applies to former-DAF ERPs and former-SWM ERPs. Several witnesses for DEP and Applicant testified that Applicant was entitled to the New Permit upon satisfaction of the volumetric requirements of Basis of Review Section 5. For example, Mr. Wright testified that the water quality requirements for the New Permit required only a "cookbook calculation" to determine volume. (Vol. I, p. 204). Agreeing with a question that analysis of the water quality portion of the system requires "simply a straightforward mathematical calculation," Mr. Wright testified that the quality of discharged water, following treatment, will comply with state water quality standards in storms producing no more than 2.5 inches of runoff. (Vol. I, pp. 210-11). When asked to explain his answer, Mr. Wright testified, "It's kind of an implied situation, in that if you follow the guidelines that you are required to follow with respect to the calculations of water quality, that the end product is going to be in compliance with state standards." (Vol. I, p. 211). DEP witnesses agreed with Mr. Wright's analysis. For instance, Mr. Bateman testified, "The stormwater portion of the Basis of Review gets at that question [meeting water quality standards] by stating, 'if you follow the design criteria in the basis, you are presumed to meet water quality standards.'" (Vol. II, p. 40). Mr. John Iglehart, the program administrator for DEP's South District Office in Fort Myers, testified on the same point: "if . . . you meet the criteria, the engineering criteria, than you have met the presumption that you meet the rule." (Vol. III, p. 52). Mr. Myers also agreed, testifying, "with the stormwater management system, it's for the most part, let's say, fairly cut and dried as far as meeting criteria that is established within these rules and Basis of Review." (Vol. III, p. 144). He added: "Since the criteria for reviewing stormwater management systems and the discharge is based upon a presumed compliance with stormwater criteria and with state water quality, it is presumed it [the proposed system] does meet it." (Vol. III, p. 148). Mr. Bateman explained the historic basis for the water quality presumption given surface water management systems that meet the volumetric requirements: the ERP is a combination of the surface water management rules and the environmental . . ., the dredge-and-fill, and they didn't merge, they didn't marry very well in certain areas. In stormwater we look at--it's a technology- based criteria. We say, "If you build it this way, treat 80 percent of the average annual pollutant load, we're going to give you the permit on the presumption that you're doing the best you can. You're going to meet standards. Once you get into the wetlands, we take--we put on whole new sets of glasses. ALJ: Are you saying that the old dredge-and- fill is more performance-based, and the old MSSW is more technology-based, in that if you've put in the required technology, you've done your job? WITNESS: That is--yes. Dredge-and-fill is a more case by case. We look at the water quality. We look at ambient conditions. We look at hydrographics [here, largely tidal flushing]. It's more like a waste load allocation in that we're very specific. In stormwater, we can't afford to be. MS. HOLMES: So what you're saying is you can't point to the specific rule provision or regulation that excludes these criteria from surface water management systems? WITNESS: Well, you have to read [Basis of Review] Section 4 as a whole. 4.1 is specific to wetlands and other surface waters. 4.2 is environmental review. I mean, if you look at the thing in total, and the--and I realize it's confusing. But these rules are exactly the same in all the water management districts. They were developed together as the wetland criteria, the new dredge-and-fill criteria. They're exactly the same. The stormwater rules of all the [water management districts] is all different. That is for another day, making those all consistent. So these environmental wetland- type dredge-and-fill criteria are all the same, and they refer to in-water impact. [All references in the transcript to "end water" should have been "in-water."] ALJ: What do you mean by that term, "in- water impact?" WITNESS: In other words, dredge-and-fill impact. Construct and--I can't-- MS. HOLMES: May I continue, then? ALJ: Let him answer. What were you going to say? WITNESS: I think it takes a little knowledge of how these [rules] developed to know how they're applied, unfortunately. In other water management districts, it's clearer that these are in-water impacts. (Vol. II, pp. 57-59). In testifying to the exclusivity of the volumetric requirements in Basis of Review Section 5, with respect to former-SWM ERPs, these witnesses likewise opined that the secondary-impact analysis required in Basis of Review Section 4 also was inapplicable to the New Permit. For example, after testifying both ways on the necessity of considering secondary impacts in issuing former-SWM ERPs, Mr. Bateman concluded, "I'm not sure that [the requirement of considering secondary impacts] applies in this case. Certainty the rules apply, I mean, the rules apply. But certain rules are not applicable in this particular instance. I mean, I'm trying to think of a secondary impact associated with stormwater system, and it's difficult for me to do so." (Vol. II, p. 45). Mr. Bateman then testified that DEP did not consider such secondary impacts, as additional boat traffic, and probably did not consider cumulative impacts, such as other marinas. (Vol. II, pp. 51-52). In response to a question asking to what extent DEP considered post-development inputs of contaminants, such as heavy metals, when issuing a former-SWM ERP, Mr. Bateman testified: I have to tell you, very little. I mean, we--stormwater is pretty black and white. The link to secondary and cumulative impact is generally associated with in-water impact. And I realize the line is a little grey here. When we build a Wal-Mart, we don't think about how many cars it's going to put on [U.S. Route] 41 and what the impact might be to an adjacent lake. We just don't. It would be a little burdensome. In this case, I mean, it's a little greyer. (Vol. II, p. 47). Mr. Bateman was then asked to compare the relative impacts from a vacant, but developed, upland without a surface water management system with a proposed activity that would add a surface water management system to facilitate an intensification of land uses on the site so as to add new contaminants to the runoff. Mr. Bateman testified that DEP would apply only the volumetric requirement and not address the complex issue of weighing the potential environmental benefit of a new surface water system against the potential environmental detriment of contaminant loading (at least in storm events greater than the design storm event). Mr. Bateman explained: "The way it works, it is not a water quality-based standard. In other words, we don't go in and say it's so many pounds [of contaminants] per acre per year now. We're going to make it this many pounds per acre per year, and look at it in a detailed fashion. We do the [Best Management Practices], retain an inch and you're there." (Vol. II, p. 49). Agreeing with Mr. Bateman that DEP was not required to consider secondary impacts resulting from the regulated activity, Mr. Iglehart testified: "It's our thought that we don't really look at secondary and cumulative impacts for the stormwater permit. . . . If it [the former-SWM ERP application] meets the criteria, it gets the permit. That--in the ERP, the previous dredge-and-fill side looks at the secondary and cumulative. The stormwater just--like Mr. Bateman testified." (Vol. III, p. 52). After some ambivalence, Mr. Myers also testified that DEP was not required to consider secondary impacts for the New Permit: WITNESS: . . . I did not or I do not consider secondary impacts for the stormwater management system. MS. HOLMES: So, what about cumulative impacts? WITNESS: No. MS. HOLMES: So it's your testimony that you did not review secondary and cumulative impacts-- WITNESS: That's correct. MS. HOLMES: --of this system? WITNESS: What I can say is that the existing system out there, from what I can tell, does not have any stormwater treatment. Basically, it's running off into the canals. The proposed project will provide stormwater treatment for, not only the new construction, which is proposed mainly on the northern peninsula, but it is also provided for that area which is now existing, it will provide stormwater treatment for that area also. And I consider that--I don't consider that to be a secondary impact. I see it as an offsetting improvement to potential as far as the water quality. (Vol. III, pp. 144-45). As discussed in detail in the conclusions of law, these witnesses have misread the provisions of the Basis of Review applicable to the New Permit. As noted in the conclusions of law, the requirements in the Basis of Review of analysis of secondary and cumulative impacts upon water quality and manatees are not limited to in-water or former-DAF activities. Satisfaction of Basis of Review Section 4 Direct vs. Secondary Impacts In terms of construction, the direct impacts of the proposed surface water management system are negligible. Nothing in the record suggests that the construction of the proposed system will violate any of the requirements of Basis of Review Section 4. In terms of maintenance, the direct impacts of the proposed surface water management system are negligible, except for the omission from the New Permit of any provision for the safe disposition of the contaminant removed from the underground vaults. However, the maintenance issues are better treated with the operation issues. In terms of operation, the direct impacts of the proposed surface water management system are substantial. As discussed in the conclusions of law, the analysis of the direct impacts of the operation of the proposed system is limited to the current level of uplands and marine activity at the marina. These direct impacts involve two aspects of the operation of the proposed system: the design capacity and the inspection and maintenance (including disposal of sediment) of the system components. As discussed in the conclusions of law, the secondary impacts involve the intended and reasonably expected uses of the proposed system. These impacts consist of the increased uplands and marine uses associated with the addition of 100 new wet slips, 227 new dry slips, and 115,000 square feet of building space with a restaurant. Apart from their contention that Applicant is required only to satisfy the volumetric requirements of Basis of Review Section 5, Applicant and DEP have contended that Petitioner is estopped from raising direct and secondary impacts because DEP considered these impacts when issuing the Original Permit four years ago. Perhaps the most obvious factual problem with this contention is that it ignores that the New Permit authorizes, for the first time, the construction of the 227 new dry slips and 115,000 square feet of buildings. As counsel for DEP pointed out during the hearing, the Original Permit was a DAF permit and did not extend to these upland uses. The contention that DEP considered these developments as secondary impacts because they were shown on drawings attached to the Original Permit gives too much significance to nonjurisdictional background items shown in drawings without corresponding textual analysis. More generally, the efforts of DEP and Applicant to restrict the scope of this case rely on a misreading of Original Permit Specific Condition 5. The purpose of Original Permit Specific Condition 5 is to "ensure a net improvement to water quality." The purpose of each of the requirements under Specific Condition 5 is to achieve an actual, not presumptive, improvement in water quality. Prohibiting the issuing agency from fully analyzing the direct and secondary impacts of the proposed surface water management system reduces the likelihood that the ensuing New Permit will perform its role, as envisioned in the Original Permit, of helping to achieve an actual, net improvement in water quality. The concept of a "net" improvement is exactly what DEP's witnesses disclaim having done in this case--balancing the potential environmental benefits to the water resources from the proposed surface water management system against the potential environmental detriments to the water resources from the development and land uses that are intended or reasonably expected to result from the construction of the proposed system. The failure to analyze the net gain or loss inherent in this important provision of Specific Condition 5.B undermines the likelihood that the effect of Specific Condition 5.B--a net improvement in water quality--will be achieved. It is therefore illogical to rely on Specific Condition 5.B, as DEP does, as authority for an artificially constrained analysis of the eligibility of the proposed system for a former-SWM ERP. The estoppel argument also ignores that Original Permit Specific Condition 5.B anticipated that the issuing agency would be SFWMD. It is unclear how the parties to the Original Permit, including DEP, would bind what appeared at the time to have to be SFWMD in the exercise of its lawful authority in issuing SWMs or former-SWM ERPs. The attempt of Applicant and DEP trying to limit the scope of this case also overlooks numerous changed circumstances since the issuance of the Original Permit. Changed circumstances militating in favor of the comprehensive analysis mandated for former-SWM ERPs include: increased trends in manatee mortality; increased boating pressure; persistent water quality violations in terms of dissolved oxygen, copper, and total coliform bacteria; a dramatic deterioration in dissolved oxygen levels; the initial presentation for environmental permitting of the previously unpermitted 227 additional dry slips and the 115,000 square feet of buildings; the current canal bottom profiles resulting from excessively deep maintenance dredging; the absence of an updated flushing study; and the failure to dredge the flushing canal required by the Original Permit. Disregarding the environmental and water quality requirements of Basis of Review Section 4 in this case would thus repudiate Specific Condition 5.B, especially when, among other things, the water quality of the canals has deteriorated dramatically with respect to dissolved oxygen, the canals continue to suffer from serious copper violations, the canals were recently maintenance dredged to excessive depths, no flushing study has examined these subsequent developments, and the intended uses to be facilitated by the New Permit more than double the capacity of the existing marina. 2. Water Quality The direct impacts of the proposed surface water management system, based on current levels of uplands and marine use at the marina, would adversely affect the quality of the receiving waters, in violation of Basis of Review Section 4.1.1(c). The excessively increased depths of the canals, especially with respect to the substantially widened depths of the north canal, raise the potential of water quality violations, especially given the history of this site. Potential sources of contaminants exist today in the canal bottoms, uplands, and marine activity associated with the marina. The potential for water quality violations, especially with respect to dissolved oxygen, increases in the absence of an updated flushing study. The potential also increases with the introduction of liveaboards and failure to dredge the flushing canal (or its replacement with culverts). In the face of these current threats to water quality, the New Permit fails to require a system with adequate capacity to accommodate fairly frequent storm events and fails to impose clear and enforceable inspection, maintenance, and disposal requirements for the underground vaults. Although better, the inspection and maintenance requirements for the stormwater inlets and boat wash area unnecessarily present enforcement problems. The effect of these failures in design capacity and inspection and maintenance is synergistic. Deficiencies in vault capacity mean that storms will more frequently resuspend the settled contaminants in the vaults and flush them out into the canal waters. Excessively long maintenance intervals and poor maintenance procedures will increase the volume of contaminants available to be flushed out into the canal waters. Improper disposition of removed contaminants endangers other water resources. The introduction of untreated or inadequately treated water into the canals means the introduction of two substances that will contribute to the current water quality violations. Organics, such as from the boat wash operations and other uplands uses, will raise biochemical oxygen demand, which will accelerate the deterioration in dissolved oxygen levels. Copper removed during boat wash operations, leaching from painted hulls, or remaining in the uplands from past marina operations will also enter the canals in this fashion. On these facts, Applicant has failed to provide reasonable assurance that the operation of the proposed surface water management system will not result, in the long-term, in water quality violations. Applicant has failed to demonstrate that the operation of the proposed system, even as limited to existing levels of use of the uplands and marine waters, will not contribute to existing violations of dissolved oxygen and copper levels. Obviously, the situation is exacerbated by consideration of the uses intended and reasonably expected to follow the construction of the proposed system. With the growing popularity of boating in Lee County over the past 20 years, it is reasonably likely that an expanded marina operation, located close to downtown Fort Myers, will successfully market itself. Thus, many more boats will use the marina because it will offer more wet and dry slips and new buildings, including a restaurant, and the pressure on water quality will intensify with the intensification of these uses. The added intensity of upland and marine uses will contribute to the above-described violations of water quality standards for dissolved oxygen and copper, probably will contribute to the above-described violations of water quality standards for total coliform bacteria and lead, and may contribute to the recurrence of water quality violations for other parameters for which the canals were previously in violation. On these facts, Applicant has failed to provide reasonable assurance that the direct and secondary impacts of the proposed system will not adversely affect the water quality of the canals. 3. Manatees and Manatee Habitat By letter dated June 26, 1998, from a DEP Environmental Specialist to a DEP permitting employee, the Environmental Specialist provided an initial opinion concerning the revisions that Applicant sought to the Original Permit so as to allow liveaboards, replace the flushing canal with culverts, and relocate the travel lift to the north canal. The letter accompanies a Manatee Impact Review Report, also dated June 26, 1998. The Manatee Impact Review Report notes the pending application for the New Permit. The report considers at length the extent of manatee use of Deep Lagoon and the nearby portions of the Caloosahatchee River. The Manatee Impact Review Report states: This project [i.e., the relocation of the boat lift to the north canal, addition of liveaboards, and conversion of the flushing canal to flushing culverts] is expected to add a significant number of boats to this system, significantly increase the level of boat traffic, and change boat traffic patterns in the study area. The vessels from this project are expected to produce significant adverse impacts to manatees that use the Deep Lagoon in the immediate vicinity of the project, as well as in the boater's sphere of influence of the project. Secondary adverse impacts include lethal and sublethal watercraft-related injuries, disturbance contributing to stress, and alteration of natural behaviors. The secondary impacts expected with this project are compounded by the cumulative secondary effects from other facilities in this system. Just south of this project site, another marina was recently constructed (Sun City Corporation aka Gulf Harbor Marina aka River's Edge), which has approximately 190 wet slips. Since October 1995, there have been seven watercraft-related deaths within five miles of this project location. The Gulf Harbor Marina was constructed in late 1995, and was almost fully occupied during 1996. Watercraft-related manatee deaths increased significantly during this time, with one in December 1995, two in 1996 and four in 1997. Additional on-water enforcement by the City of Cape Coral was considered part of the offsetting measures to address the expected impacts to manatees from increases in boat density. This offsetting measure, however, appears to be ineffectual at this time. The Manatee Impact Review Report concludes that the north canal and its mouth are "particularly important" for manatee because of the availability of freshwater from the adjoining Iona Drainage District ditch immediately north of the north canal and "historical use indicates that this area appears to be the most frequently used area in the Deep Lagoon system." The report cautions that the relocated travel lift may significantly increase the number of boats in the little-used north canal, whose narrowness, coupled with moored, large boats on the one side, "would produce significant, adverse impacts to the endangered manatee." The Manatee Impact Review Report finds that Applicant failed to provide reasonable assurance regarding the conservation of fish and wildlife, unless several new conditions were added. These conditions include prohibitions against boat launching along the shoreline of the north canal and the addition of manatee-exclusion grating to any culverts that may be approved. As defined in this recommended order, the direct impacts upon manatees from the proposed surface water management system would be moderate. As defined in this recommended order, direct impacts would not involve any increase in boating pressure. The greater impacts would be in the deterioration of two measures of water quality that are crucial to manatees: dissolved oxygen and copper. However, the secondary impacts are dramatic, not de minimis, and arise from the intended and reasonably expected uses to follow from the construction of the proposed surface water management system. The increased boat traffic intended and reasonably expected from more than doubling the marina capacity, through the addition of 100 wet slips and 227 dry slips, and the addition of 115,000 square feet of buildings, including a restaurant, would adversely impact the value of functions provided to manatees by the affected surface waters. Manatee mortality has increased as boat traffic has increased. Substantial numbers of boaters have ignored speed limits. Quality manatee habitat in this critical area along the Caloosahatchee River is not plentiful. On these facts, Applicant has failed to provide reasonable assurance that the secondary impacts of the proposed system will not adversely impact the abundance and diversity of wildlife and listed species, of which manatees are one, and the habitat of wildlife and listed species. 4. Minimization and Mitigation Due to their contention that Basis of Review Section 4 does not apply to this case, DEP and Applicant did not demonstrate compliance with the minimization and mitigation sections of Basis of Review Section 4. However, the record supports the possibility of design alternatives for water quality impacts, if not manatee impacts, that DEP and Applicant must consider before reanalyzing the direct, secondary, and cumulative impacts of the proposed system on the water resources and, if appropriate, potential mitigation options. Mr. Bateman testified that SFWMD is the only district that permits surface water management systems relying on the settling out of sediments in the bottom of a storage-type detention system. (Vol. II, p. 18). He explained that other districts rely on systems that, taking advantage of the three to four feet typically minimally available between ground surface and the top of the water table, retain the runoff and allow it to percolate into the ground. (Vol. II, p. 19). One relatively straightforward design alternative, which would address water quality issues, would be to perform a flushing study; analyze applicable drainage level of service standards imposed by state, regional, and local authorities; and increase the capacity of the surface water management system to accommodate the runoff from storms of sufficient size and frequency that would be accommodated by the proposed system. Another feature of this design alternative would be to impose for each component of the system a detailed, enforceable program of inspection, maintenance, and contaminant-disposal. This program would incorporate the manufacturer's recommendations for the manner and minimum frequency of inspection and maintenance, but would require more frequent removal of contaminated sediments during periods when larger storms are more numerous (e.g., a specified wet season) or more intense (e.g., a specified hurricane season), as well as any periods of the year when the marine and upland uses are greatest (e.g., during the winter season, if this is the period of greatest use). As testified by Mr. Bateman, the proximity of the water table to the surface, as well as South Florida land costs, discourage reliance upon a conventional percolation-treatment system, even though the site's uplands are 5 feet NGVD and the water table is 1.2 feet NGVD. The bottom of the proposed system is 2.5 feet NGVD, which leaves little soil for absorption. If the nature of the contaminants, such as copper, does not preclude reliance upon a percolation-treatment system, DEP and Applicant could explore design alternatives that incorporate more, shallower vaults, which would increase the soil layer between the bottom of the vaults and the top of the water table. If the technology or contaminants preclude reliance upon such an alternative, the parties could consider the relatively costly alternative, described by Mr. Bateman, of pool-like filters with an "actual filtration device." (Vol. II, pp. 19-20). The preceding design alternatives would address water quality concerns, including as they apply to manatees, but would not address the impact of increased boating upon manatees. The record is not well developed in this regard, but DEP and Intervenor have considerable experience in this area, and it is premature to find no suitable means of eliminating or at least adequately reducing the secondary impacts of the proposed system in this crucial regard as well. In any event, Applicant has failed to consider any design alternatives to eliminate or adequately reduce the direct and secondary impacts of the proposed surface water management system. Having failed to consider minimization, DEP and Applicant have failed to identify the residual direct and secondary impacts that might be offset by mitigation. Applicant has thus failed to mitigate the direct and secondary impacts of the proposed surface water management system.

Recommendation It is RECOMMENDED that the Department of Environmental Protection enter a final order revoking its determination of an exemption for maintenance dredging in DOAH Case No. 98-3901 and denying the application for an environmental resource permit in DOAH Case No. 98-5409.

WILLIAM BYRD vs CITY OF TREASURE ISLAND AND DEPARTMENT OF ENVIRONMENTAL PROTECTION, 95-004155 (1995)
Division of Administrative Hearings, Florida Filed:Treasure Island, Florida Aug. 24, 1995 Number: 95-004155 Latest Update: Jan. 17, 1996

Findings Of Fact At all times to the issues herein the Department of Environmental Protection was the state agency in Florida responsible for the regulation of water pollution and the issuance of dredge and fill permits in the specified waters of this state. Mr. Byrd has been a resident of the City of Treasure Island, Florida for many years and resides at 123 123rd Avenue in that city. His property is located on Boca Ciega Bay next to a public boat ramp operated by the City. On April 12, 1995, the City of Treasure Island applied to the Department of Environmental Protection for a permit to construct a dock six feet wide by seventy-five feet long, located on the edge of its property on which the public boat ramp is located. This property is located in a basin off Boca Ciega Bay, which is classified as a Class III Outstanding Florida Water. The dock involves the placement of pilings in the water, and the construction of a walkway thereon. In order to be obtain a permit, the applicant must provide the Department with reasonable assurances that the proposed project will not degrade water quality and will be in the public interest. The project is permanent in nature, but the temporary concerns raised by construction have been properly addressed in the permit. In the instant case, the dock is intended to accommodate the boating public which will utilize it to more safely launch, board, debark, and recover small boats at the ramp in issue. The dock will be equipped with a hand rail which will increase the safety of the project. Evidence establishes that without the dock, boaters have to enter the water to launch and recover their boats on a ramp can be slippery and dangerous. The site currently in use as a boat ramp, a part of which will be used for the dock, is almost totally free of any wildlife. No evidence could be seen of any sea grasses or marine life such as oysters, and there was no indication the proposed site is a marine habitat. Manatees do periodically inhabit the area, and warning signs would be required to require construction be stopped when manatee are in the area. The water depth in the immediate area and the width of the waterway is such that navigation would not be adversely impacted by the dock construction, nor is there any indication that water flow would be impeded. No adverse effect to significant historical or archaeological resources would occur and taken together, it is found that the applicant has provided reasonable assurances that the project is within the public interest. Concerning the issue of water quality, the applicant has proposed the use of turbidity curtains during construction which would provide reasonable assurances that water quality would not be degraded by or during construction. The water depths in the area are such that propeller dredging and turbidity associated therewith should not be a problem. No evidence was presented or, apparently is on file, to indicate any documented water quality violations at the site, and it is unlikely that water quality standards will be violated by the construction and operation of the structure. The best evidence available indicates there would be no significant cumulative impacts from this project. Impacts from presently existing similar projects and projects reasonably expected in the future, do not, when combined with the instant project, raise the possibility of adverse cumulative degradation of water quality or other factors of concern. By the same token, it is found that secondary impacts resulting from the construction of the project would be minimal. It is also found that this project is eligible for an exemption from the requirements to obtain a permit because of the Department's implementation on October 3, 1995 of new rules relating to environmental resources. However, the City has agreed to follow through with the permitting process notwithstanding the exemption and to accept the permit including all included conditions. This affords far more protection to the environment than would be provided if the conditions to the permit, now applicable to this project, were avoided under a reliance on the exemption to which the City is entitled under current rules. To be sure, evidence presented by Mr. Byrd clearly establishes the operation of the existing boat ramp creates noise, fumes, diminished water conditions and an atmosphere which is annoying, discomfiting, and unpleasant to him and to some of his neighbors who experience the same conditions. Many of the people using the facility openly use foul language and demonstrate a total lack of respect for others. Many of these people also show no respect for the property of others by parking on private property and contaminating the surrounding area with trash and other discardables. It may well be that the presently existing conditions so described were not contemplated when the ramp was built some twenty years ago. An increase in population using water craft, and the development and proliferation of alternative watercraft, such as the personal watercraft, (Ski-Doo), as well as an apparent decline in personal relations skills have magnified the noise and the problem of fumes and considerably. It is not likely, however, that these conditions, most of which do not relate to water quality standards and the other pertinent considerations involved here, will be increased or affected in any way by the construction of the dock in issue.

Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is, therefore: RECOMMENDED that the Department of Environmental Protection issue to the city the requested permit to construct the dock in issue at the existing public boat ramp at the east end of 123rd Avenue right of way in the City of Treasure Island. RECOMMENDED this 12th day of December, 1995, in Tallahassee, Florida. ARNOLD H.
