The Issue The issues to be determined in this proceeding are: whether the challengers have standing; and (2) whether Proposed Rule 40E-8.221(2) is an invalid exercise of delegated legislative authority.
Findings Of Fact Based on the parties' stipulations and the evidence adduced at the final hearing, the following findings of fact are made: The Parties The District is a government entity existing and operating pursuant to chapter 373, Florida Statutes, as a multi- purpose water management district. The District has the power and duty to adopt MFLs consistent with the provisions of part I of chapter 373. Sanibel is a barrier island sanctuary in Lee County and a duly-formed municipality with a population of more than 6,000. Sanibel is situated at the mouth of the Caloosahatchee River, within the Caloosahatchee's greater estuarine area. Sanibel is known primarily for its natural beauty, including clear blue waters, shell beaches, world-class sport fisheries, and wildlife refuges. That is why tourists come from around the globe to visit Sanibel, and why Sanibel's residents move and remain there. Sanibel actively participated in the rulemaking process for the Proposed Rule from its inception. Sanibel submitted two technical comment letters to the District during the development of the Proposed Rule. Sanibel's natural resources director, James Evans, attended numerous public and technical meetings associated with the development of the Proposed Rule, speaking on the record at each of the public meetings prior to the adoption hearing by the District's governing board. The Town, located on Estero Island in Lee County, is also a barrier island community and duly-formed municipality with a population of more than 6,000. The Town is situated just south of the mouth of the Caloosahatchee River and on the southeastern edge of the Caloosahatchee River's greater estuarine area. The Town is known primarily for its natural beauty, including clear blue waters, shell beaches, world-class sport fisheries, and wildlife refuges. Cape Coral is a duly-formed municipality in Lee County and is the largest city between Tampa and Miami, with a population in excess of 150,000. Cape Coral is bordered on the south by the Caloosahatchee River and has over 400 miles of navigable canals and waterways, all of which are within the Caloosahatchee River's greater estuarine area. In addition, Cape Coral has an assigned load reduction allocation under the Basin Management Action Plan (BMAP) for the Caloosahatchee River Estuary (CRE) due to it being designated as impaired for dissolved oxygen and nutrients. Maintaining sufficient flow in the Caloosahatchee River would have a direct impact on Cape Coral's ability to meet its assigned load reduction allocation. In addition to living on or near the water, a substantial number of the residents of Sanibel, Cape Coral, and the Town engage in water-based recreational activities such as swimming, fishing, boating, kayaking, paddle boarding, bird watching, and nature observation in and around the Caloosahatchee River's greater estuarine area. Fort Myers is a duly-formed municipality in Lee County and has a population of approximately 80,000. Fort Myers is bordered by the CRE throughout its entire jurisdictional boundary. Fort Myers owns and maintains a yacht basin (Ft. Myers Yacht Basin), which includes a mooring field and an anchorage field in the Caloosahatchee River. Fort Myers presented testimony that commercial crabbing and recreational fishing have declined and that it has suffered economic harm due to water quality issues. Fort Myers owns the submerged land in the Caloosahatchee River from Marker 39 to Marker 58, and islands in the river. One such island will be used as a park for recreational activities such as canoeing, kayaking, and hiking for visitors to enjoy the Caloosahatchee River. Fort Myers also owns and operates piers and a public boat ramp within the Caloosahatchee River. Fort Myers' dock master has observed declines in seagrasses in the Caloosahatchee River during his 19-year career working at the Ft. Myers Yacht Basin. Fort Myers has adopted a Harbor Management Plan for the management of its mooring and anchorage fields in the Caloosahatchee River. Fort Myers has also been assigned a load reduction allocation under the BMAP for the CRE, and is responsible for a certain amount of pollution reduction over time. Bonita Springs is a municipality of more than 50,000 in Lee County. The borders of Bonita Springs include portions of Estero Bay, which, along with San Carlos Bay and the Caloosahatchee River, is part of the greater Lower Charlotte Harbor Estuary. Bonita Springs includes wildlife refuges, such as the Estero Bay Aquatic Preserve and Lovers Key State Park and Recreation Area. While Bonita Springs' strategic priorities include environmental protection and water quality, it does not have environmental staff or test water quality. Bonita Springs participates in Estero Bay Management and the Charlotte Harbor National Estuary Program (CHNEP). Bonita Springs provides financial assistance to the Caloosahatchee Citizen Sea Grass Gardening Project. Concerns regarding harm to the CRE and tape grasses are shared by a significant number of residents in Bonita Springs and Estero, including injury to the quality of life and recreational uses such as swimming, boating, and kayaking in the waterways. Estero is a municipality of more than 30,000 in Lee County. Estero borders the eastern portion of Estero Bay. Estero includes wildlife refuges, such as Estero Bay Aquatic Preserve and Koreshan State Park. While Estero has environmental policies, it does not have environmental staff or test water quality. Estero makes financial contributions to CHNEP. Estero is concerned that the Proposed Rule will affect its water quality, which could affect its residents' quality of life. Estero believes it could be harmed by poor water quality because its residents are portable retirees who can move away, or tourists who can choose not to visit. Captiva Island is situated at the mouth of the Caloosahatchee River, within the Caloosahatchee's greater estuarine area. CCP is a Florida not-for-profit corporation representing property owners, businesses, and the community of Captiva Island. Captiva Island is part of unincorporated Lee County and is located north of Sanibel. CCP has 200 financial contributors comprised of property owners, businesses, and residents on Captiva Island. CCP's mission includes protection of clean off-shore water, diverse and healthy marine life, and robust native vegetation along with the protection of mangrove fringe and water quality. CCP works with Lee County on provisions of the County's comprehensive plan, which include the quality of adjacent waters. CCP relied on the expertise of James Evans, the director of natural resources for Sanibel, and on the Sanibel- Captiva Conservation Foundation (SCCF). CCP was advised that the Proposed Rule was not sufficient to protect the environment and Vallisneria americana (Vallisneria) or tape grass during the dry season. Caloosahatchee River and Estuary The watershed of the Caloosahatchee River covers approximately 861,058 acres. The watershed consists of four sub-watersheds, three of which are upstream of the S-79 structure. The Tidal Caloosahatchee Basin sub-watershed (estuarine system) is downstream of the S-79 structure. The S-79 structure captures all the upstream discharges of fresh water that go into the estuarine system through the S-79 structure. Major tidal tributaries of the Tidal Caloosahatchee Basin are the Orange River and Telegraph Creek, which drain into the upper estuary downstream of the S-79 structure. Fresh water inflows from these and other tributaries also contribute fresh water into the estuarine system. The Caloosahatchee River was originally a natural watercourse running from its origin at Lake Flirt to San Carlos Bay. It is currently defined as the "surface waters that flow through the S-79 structure, combined with tributary contributions below S-79 that collectively flow southwest to San Carlos Bay." Fla. Admin. Code. R. 40E-8.021(2). Man-made alterations to the Caloosahatchee River began as early as 1884, but major alterations began in the 1930s with the authorization and construction of the C-43 Canal. The C-43 Canal runs 41.6 miles from Lake Okeechobee at Moore Haven, i.e., from the S-77 structure, to Olga, i.e., the S-79 structure. The C-43 Canal serves as a conveyance feature to drain water from the three sub-watersheds located upstream of the S-79 structure and convey regulatory discharges of water from Lake Okeechobee. In 1957, the United States Army Corps of Engineers (USACOE) prepared a report focused on drainage, flood control, and navigation needs of the Caloosahatchee River Basin, and one recommendation was construction of the S-79 structure. The key objectives of the S-79 structure were to eliminate undesirable salinity in the lower Caloosahatchee River, prevent the rapid depletion of water supplies, and raise the prevailing dry weather water table levels. The S-79 structure was constructed in 1965. It is a lock and dam structure that is also known as the Franklin Lock and Dam. The S-79 structure captures all upstream fresh water discharges that go into the CRE. The S-79 structure demarcates the head of the CRE, which extends 26 miles downstream to Shell Point, where it empties into San Carlos Bay in the southern portion of the greater Lower Charlotte Harbor Estuary. Most of this surface water flow takes a southerly route, flowing to the Gulf of Mexico under the Sanibel Causeway that crosses San Carlos Bay. When fresh water inflows are high, tidal action pushes some of this water back up into Matlacha Pass and Pine Island Sound. Additionally, some water exits to the south and flows into Estero Bay through Matanzas Pass. Salinity exhibits a strong gradient in the CRE. Changes in the watershed upstream of the S-79 structure have profoundly influenced the delivery of fresh water to the CRE. Runoff is now more variable with higher wet season flows and lower dry season discharges. Large volumes of fresh water during the wet season can flush salt water from the tidally-influenced sections of the water body, resulting in low salinity conditions throughout most of the CRE. In contrast, fresh water inflow at the S-79 structure can stop entirely during the dry season, especially during significant drought events. This results in saline intrusion that can extend upstream to the S-79 structure. Fluctuations of this magnitude at the head and mouth of the system cause mortality of organisms at both ends of the salinity gradient. Downstream of the S-79 structure, the CRE was significantly altered by multiple dredging activities, including the removal of extensive shoals and oyster bars. Seven automobile bridges, a railroad trestle, and the Sanibel Causeway were built between the 1880s and 1960s. A large canal network was built along the northern shoreline of the CRE in Cape Coral. To provide navigational access from the canal network to deeper water, multiple access channels were dredged within the CRE. Alterations to the delivery of fresh water combined with structural changes to the tidally-influenced sections of the water body have had lasting ecological consequences. These include the loss of extensive shoals and oyster bars, loss of a flourishing bay scallop fishery, and significant decline in seagrass cover in deeper areas. MFLs An MFL is the limit at which further withdrawals would be significantly harmful to the water resources or ecology of the area. The District's rules define significant harm as the "temporary loss of water resource functions, which results from a change in surface or ground water hydrology, that takes more than two years to recover, but which is considered less severe than serious harm." Fla. Admin. Code R. 40E-8.021(31). The rule further specifies that a water body's specific water resource functions addressed by an MFL are defined in the MFL technical support document. Id. MFLs are calculated using the best information available. The regulatory agency is required to consider changes and structural alterations to watersheds, and the constraints such changes or alterations placed on the hydrology of an affected watershed. Certain waterbodies may not serve their historical hydrologic functions and recovery of these waterbodies to historical hydrologic conditions may not be economically or technically feasible. Accordingly, the regulatory agencies may determine that setting an MFL for such a water body based on its historical condition is not appropriate. Caloosahatchee MFL For the CRE, MFL criteria were designed to protect the estuary from significant harm due to insufficient fresh water inflows and were not guidelines for restoration of estuarine functions to conditions that existed in the past. The MFL criteria consider three aspects of the flow in terms of potential significant harm to the estuary: (1) the magnitude of the flow or the volume of fresh water entering the estuary; (2) the duration of time that flows can be below the recommended level before causing significant harm; and (3) the return frequency, or the number of times the MFL can be violated over a number of years before it results in significant harm, recognizing that natural climatic variability will be expected to cause fresh water inflows to fall below recommended levels at some natural frequency. The CRE MFL initially adopted in 2001 was primarily based on the salinity tolerance of one valued ecosystem component (VEC). The VEC was Vallisneria americana or tape grass, a fresh water aquatic plant that tolerates low levels of salinity. A major assumption of this approach was that flow and salinity conditions that protect Vallisneria would also protect other key organisms in the estuary. The 2001 CRE MFL was based on a regression model for estimating the relationship between surface salinity measured at the Ft. Myers monitoring station located in the Ft. Myers Yacht Basin and discharge at the S-79 structure. Although the District monitors surface and bottom salinity at multiple stations in the CRE, the Ft. Myers monitoring station is located centrally in the CRE and at the historical downstream extent of the Vallisneria habitat. The Ft. Myers monitoring station also has the most comprehensive period of record of monitoring data available. The fixed data sondes that monitor surface and bottom salinity are located at 20 percent and 80 percent of total river depth measured at mean low water. The data sondes continuously measure temperature and specific conductivity and, depending on the manufacturer, contains programs that calculate salinity. Those calculations are based on standards recognized and used worldwide by estuarine, marine, and oceanographic scientists.1/ The regression model only implicitly included inflows from the Tidal Caloosahatchee Basin sub-watershed downstream of the S-79 structure. To address this, during the 2003 re-evaluation, a linear reservoir model of Tidal Caloosahatchee Basin inflows was developed. The regression model results showed that a total inflow from S-79 plus the Tidal Caloosahatchee Basin of about 500 cubic feet per second (cfs) was required to produce a salinity of 10 at the Ft. Myers monitoring station. Thus, the 2001 CRE MFL of 300 cfs measured at the S-79 structure would produce a salinity of 10 at the Ft. Myers monitoring station only with additional inflow from the downstream Tidal Caloosahatchee Basin sub- watershed. However, that additional inflow estimate was highly uncertain. The conclusion was that actual flow measurements over a period of time were needed in order to perform more robust calibrations for the new models that were being developed. The Re-evaluation The District's re-evaluation effort began in 2010 after the Conservancy of Southwest Florida filed a petition requesting review of the Caloosahatchee MFL. At the time, the governing board denied the petition but directed staff to undertake additional research and monitoring to ensure a future revision would be supported by the best information available. The first step was to review the September 2000 Final Peer Review Report (PRR) for the initial adoption. The 2000 PRR identified several items the District should consider, including a hydrodynamic salinity model, a numerical population model for Vallisneria, quantification of habitat value for Vallisneria, and documentation of the effects of minimum flows on downstream estuarine biota. The 2000 PRR documented concerns that the current MFL was based solely on the salinity tolerance of Vallisneria and recommended using multiple indicator species. To address those recommendations, the District conducted studies to evaluate multiple ecological indicators, such as zooplankton, aquatic vegetation, oysters, benthic communities, and blue crabs, in the Caloosahatchee from the S-79 structure to beyond Shell Point. In addition, the District collected flow data from the Tidal Caloosahatchee Basin sub-watershed for at least five years to develop watershed, flow, and hydrodynamic models that could properly simulate inflows and salinity responses. When the initial research was complete in 2016, the District published the Draft Science Document containing 11 component studies. In September 2016, the District held a two- day Science Symposium to present the 11 component studies and gather public comment. In response to public comment, the District performed additional evaluations, modeling, and updated the component studies to produce a Draft Technical Document. A Peer Review Panel reviewed the Draft Technical Document, which included the Draft Science Document. The Peer Review Panel has over 150 years of combined relevant scientific experience. The Peer Review Panel toured the CRE by air and water. The District also held a Peer Review Session to engage the public and obtain feedback. The Peer Review Panel's 2017 report (PRP report) stated that the District had "crafted a well-executed and well- documented set of field and laboratory studies and modeling effort" to re-evaluate the CRE MFL. The PRP report supported the 11 component studies, the modeling, the evaluations, and the initial proposed rule language. The Final Technical Document published in January 2018 incorporated five different models and additional science, examining the entire watershed and the criteria itself. The Final Science Document was Appendix A to the Final Technical Document and contained the scientific research and analysis that was done for the 11 component studies, the modeling, and the additional scientific analyses performed in response to public and stakeholder input. The District initiated rule development in December 2017. Rule development workshops were held in February and June 2018 and a stakeholder technical meeting was held in May 2018. The District validated the comments after each workshop and meeting, and revised the proposed rule language. The District published its Notice of Proposed Rule on July 23, 2018.2/ At its September 13, 2018, meeting, the District's governing board held a public hearing on the Proposed Rule. The mayors of Sanibel, Cape Coral, and the Town publicly commented at the hearing. After considering public comments, the governing board adopted the Proposed Rule. The District documented and responded to each public comment, memorializing the information in the Final Technical Document. Later, after the rule workshops and May 2018 technical meeting, the District prepared and presented all of the updated information, including public comment, at the September 2018 adoption hearing. Thus, the District's re-evaluation process was open and transparent. The Re-evaluated Caloosahatchee MFL The science supporting the re-evaluation involved a comprehensive assessment of the effects of diminished dry season fresh water inflows on the CRE. The dry season was chosen for two reasons. First, because it is well-established that the upstream migration of salt combined with reduced fresh water inflow alters the health and productivity of estuarine habitats. Second, because the dry seasons are the times when the current MFL criteria are likely to be exceeded or violated. The 11 component studies targeted specific concerns regarding physical and ecological characteristics. Together they offered a holistic understanding of the negative effects of diminished fresh water inflow on estuarine ecology. The re-evaluated MFL criteria were developed using a resource-based approach. The approach combined the VEC approach and the habitat overlap concept. The habitat overlap approach is based on the idea that estuaries serve a nursery function and salinity determines the distribution of species within an estuary, including distribution during different life stages. The combined approach studied the minimum flow requirements of the various indicator species in terms of magnitude, duration, and return frequency, resulting in the following three aspects of the flow: (1) for magnitude, a 30-day moving average flow of 400 cfs measured at the S-79 structure; for duration, an MFL exceedance occurs during a 365-day period when the 30-day moving average flow at S-79 is below 400 cfs and the 30-day moving average salinity exceeds 10 at the Ft. Myers salinity monitoring station; and (3) for return frequency, an MFL violation occurs when an exceedance occurs more than once in a five-year period. The magnitude component is based on the salinity requirements of Vallisneria, along with results from the 11 studies modeling salinity and considering the salinity requirements of the other VECs. The duration component is based mainly on the estimates of rate of loss of Vallisneria shoots when salinity rises above 10 and the recovery rate of the shoots when salinities fall back below 10. Return frequency was determined based on long-term rainfall records rather than flow measurements from the S-79 structure, which the PRP report felt was well justified. In addition to the component studies, the re-evaluated MFL criteria and existing recovery strategy were evaluated using a suite of hydrologic and ecological models simulating long-term fresh water inflow to the CRE associated with varying management options, the resulting salinity in the CRE, and the ecological response of indicator species that are sensitive to low fresh water inflows. Five models were utilized. Three models simulated fresh water inflows to the CRE: two for S-79 flows; and one for Tidal Caloosahatchee Basin sub-watershed flows. The other two models were a three-dimensional hydrodynamic salinity model and a Vallisneria model. Tidal Caloosahatchee Basin sub-watershed has a number of tributaries that drain fresh water into the CRE. The flow at several of the tributaries was monitored for a five-year period. The measured flow was used to calibrate a watershed model and conduct a long-term simulation. The results showed an average fresh water inflow for all seasons of approximately 430 cfs. The average fresh water inflow during the dry season was 245 cfs while the wet season average fresh water inflow was 613 cfs. Fresh water inflow from the Tidal Caloosahatchee Basin sub- watershed was approximately 20 percent of total fresh water inflow to the CRE while 80 percent was released through the S-79 structure. Petitioners' and Intervenors' Objections 400 cfs Is Too Low Sanibel relied on a memorandum prepared by Dr. David Tomasko (Tomasko report) concerning his company's review of the January 2018 Final Technical Document supporting the Proposed Rule. The Tomasko report, dated October 23, 2018, was in the form of a "technical memorandum" outlining "preliminary findings." The Tomasko report was admitted as a joint exhibit; however, Dr. Tomasko did not testify at the final hearing. The Tomasko report is hearsay that was not used to supplement or explain competent direct evidence. Although hearsay is admissible in this proceeding, it cannot be the sole basis for a finding of fact.3/ See § 120.57(1)(c), Fla. Stat. The District's expert witnesses, who testified at the final hearing, explained that ten of the 11 component studies identified average indicator flows at S-79 ranging from 237 to 545 cfs with standard deviations ranging from plus or minus 57 to plus or minus 774 cfs.4/ The District's experts performed three different evaluations of those flow results. They identified the mean of all the means, calculated the median of the means, and performed a probability density function. The flow results for each of the three evaluations were 381 cfs, 400 cfs, and 365 cfs, with standard deviations that ranged from plus or minus 277 cfs to plus or minus 706 cfs. The District's experts testified that the three flow results are indistinguishable from a statistical point of view. The District chose 400 cfs because it was the highest flow result, and, therefore, the most protective of the three. The Petitioners and Intervenors failed to present evidence that showed any deficiencies in the District's component studies, hydrologic, hydrodynamic, or statistical modeling, or analysis of compliance data. The preponderance of the evidence established that the District used the best available science to calculate the MFL criteria. The District did not act arbitrarily or capriciously when it chose 400 cfs as the magnitude component of the MFL criteria. Inclusion of Salinity in the MFL Criteria The preponderance of the evidence also established that Vallisneria continues to be a particularly useful indicator of environmental conditions in the CRE. It supports essential ecological goods and services, is sensitive to salinity fluctuations at the ecosystem scale, and has value to a variety of stakeholders. The location of Vallisneria habitat in the upper CRE and its negative response to increased salinity made it an excellent candidate as an ecological indicator for fresh water inflow. A combination of field monitoring, mesocosm studies, and modeling results allowed the application of Vallisneria responses as a platform to quantify the effects of high salinity duration in the upper CRE. Component Study Eight reviewed the development and initial application of a simulation model for Vallisneria in the CRE. The Vallisneria model was used to evaluate the salinity conditions that led to net annual mortality, or, in other words, the duration of high salinity exposure that led to decreased Vallisneria shoots versus the duration of low salinity conditions required for recovery. Component Study Seven included an analysis of the relationship between the number of consecutive days where salinity at the Ft. Myers monitoring station was greater than 10 and the percentage of initial Vallisneria shoots remaining at the end of each high salinity period. To further evaluate the duration element associated with the MFL criteria, the field monitoring data contained in Component Study Seven was evaluated with the mesocosm and modeling results. All three sources were analyzed similarly to derive a combined curve showing high salinity exposure duration that is significantly harmful to Vallisneria. The model also provided information that was used to quantify the duration of low salinity conditions required for Vallisneria to recover a relative fraction of shoots after high salinity exposure. Merging the exposure and recovery evaluations facilitated a determination of the unfavorable salinity duration that could significantly harm Vallisneria habitat. With significant harm defined as the environmental harm from which two years are required to recover, the determination was that Vallisneria should experience no more than 55 consecutive days of salinity greater than 10. However, stakeholders expressed concerns regarding the percentage loss of Vallisneria habitat after 55 days of high salinity exposure. In response, the District conducted further analysis of modeling results and revised the duration component to accept the stakeholder recommendation, now expressed in the Proposed Rule, of a 30-day moving average salinity greater than 10. The Petitioners and Intervenors argued that by expressing the MFL as a "flow plus salinity component" the Proposed Rule enlarges, modifies, or contravenes the specific provisions of law implemented. However, the duration component is part of compliance and represents the duration of time that flows can be below the recommended level before causing significant harm to the indicator species Vallisneria. The MFL in the Proposed Rule is a 30-day moving average flow of 400 cfs measured at the S-79 structure. Flow is both measured and operationally controlled at the S-79 structure. However, as previously found, there are other sources of fresh water entering the CRE downstream of the S-79 structure. The District does not control and cannot control these downstream sources, which modeling reveals contribute approximately 20 percent of total fresh water inflow to the CRE. By including salinity, the District can account for fresh water inflows coming from the tidal basin when there are low or no flows at S-79 since the significant harm threshold in the CRE is directly related to salinity tolerance of the indicator species Vallisneria. The District's experts also testified that salinity can be used as a flow component because it is not affected by chemical or biological processes and is an indicator of how much fresh water is entering the system.5/ Salinity is included in the duration component of the MFL criteria and is an exceedance criterion because the science established that the salinity gradient is crucial to the overall health of the CRE. Including salinity in the duration component of the MFL criteria achieves the purpose of the statutory mandate to set MFLs that are designed to avoid significant harm to the water resources and ecology of the area. No Unit of Measurement for Salinity The Petitioners and Intervenors argued that the Proposed Rule is vague because the language does not contain any units for salinity. The UNESCO calculation is the standard equation used by the estuarine and marine science community to convert specific conductivity and temperature data to salinity. The District's experts testified that the UNESCO calculation reports salinity as a ratio, which is a dimensionless number and has no units. The District uses the UNESCO calculation and performs the conversion in a spreadsheet that it maintains. In some instances, certain brands of data sondes are programmed to perform the calculation and provide the salinity number. The preponderance of the evidence established that use of the practical salinity unit (PSU) is not technically correct. PSU is a misnomer, a pseudo-unit equivalent to a unitless salinity number. The Petitioners' and Intervenors' expert witness, Dr. Anthony Janicki, conceded there is no difference between reporting salinity as unitless or as PSU. And although technically incorrect, he suggested that placing the word "practical" or putting "PSU" in the Proposed Rule would reduce confusion and vagueness. However, since the preponderance of the evidence established that use of PSU is not technically correct, the use of a pseudo-unit would actually cause confusion instead of reduce confusion. The Petitioners and Intervenors also argued that the Proposed Rule is vague because the language does not state that the method of measuring salinity is specific conductivity, or that the equation used to convert specific conductivity and temperature data to salinity is the standard developed by UNESCO. The Petitioners and Intervenors essentially argued that members of the public and those who may be regulated by the Proposed Rule are left to guess about the method or methods used to measure salinity. Because the Proposed Rule identifies and locates by latitude and longitude coordinates the Ft. Myers salinity monitoring station as the location where salinity would be measured for compliance, the Proposed Rule language is not vague. The Proposed Rule is not vague because it does not describe the data sondes, what parameters are measured by the data sondes, and how those parameters are converted to a salinity number. Salinity Monitoring Location and Mean Low Water The Petitioners and Intervenors argued that the Proposed Rule is vague for failing to define the phrase "20% of the total river depth at mean low water," and is arbitrary or capricious for failing to include more than one salinity monitoring station. Total river depth or the water column depth is a standardized measurement that is made from the surface down to the bottom of the river bed. Mean low water is commonly understood in the oceanographic and coastal sciences community as the average of all low tides over the time period defined as the national tidal datum epic. The District's expert witness, Dr. Cassondra Armstrong, testified that mean low water can be determined by using two documents prepared by the National Oceanographic and Atmospheric Administration (NOAA), i.e., the NOAA tide charts and glossary. The District's expert witnesses testified that "20% of the total river depth at mean low water" is the location of the data sonde at the Ft. Myers monitoring station that measures surface salinity. This is also the depth at which Vallisneria is located in the CRE. Since, the Proposed Rule language simply identifies the location of the existing data sonde at the Ft. Myers salinity monitoring station, the language is not vague. The preponderance of the evidence established that the Ft. Myers salinity monitoring station has two salinity data sondes, the one at 20 percent of the total river depth and the other at 80 percent. The data sonde at 20 percent of the total river depth was identified in the Proposed Rule for the following reasons. First, this is the depth where Vallisneria grows and is representative of the salinity exposure for Vallisneria. Second, it guarantees the data sonde is always submerged and able to record data. Third, it has the most comprehensive period of record of monitoring data available. As previously found, Vallisneria continues to be a particularly useful indicator of environmental conditions in the CRE. The location of Vallisneria habitat in the upper CRE and its negative response to increased salinity made it an excellent candidate as an ecological indicator for fresh water inflow. Because the preponderance of the evidence established that Vallisneria continues to be a particularly useful indicator of environmental conditions in the CRE, the choice of the Ft. Myers monitoring station is not arbitrary or capricious. Water Resource Functions vs. Environmental Values The District's MFL rule specifies that a water body's specific water resource functions addressed by an MFL are defined in the MFL technical support document. See Fla. Admin. Code R. 40E-8.021(31). The Final Technical Document identified the relevant water resource functions of the CRE as fish and wildlife habitats, estuarine resources, water supply, recreation, navigation, and flood control. The Petitioners and Intervenors argued that the environmental values listed in Florida Administrative Code Chapter 62-40, also known as the Water Resource Implementation Rule, were not adequately addressed in the Final Technical Document. A proposed rule challenge is not the proper forum to determine whether a proposed rule is consistent with the Water Resource Implementation Rule. Such a determination is within the exclusive jurisdiction of the Department of Environmental Protection under section 373.114(2), Florida Statutes. Consistency of the District's Proposed Rule with the Water Resource Implementation Rule of the Department of Environmental Protection is not a basis in this proceeding for a finding that the Proposed Rule is an invalid exercise of delegated legislative authority. Other Issues The Petitioners and Intervenors raised other issues during the hearing, although not specifically argued in their proposed final order. Since those issues were identified as disputed issues in the Joint Pre-hearing Stipulation, they are addressed below. 1. Elimination of Single-day Exceedance Criterion During the rulemaking process, Sanibel and SCCF sent the District a letter requesting justification for eliminating the single-day exceedance salinity criterion in the current rule. The District staff evaluated the available Caloosahatchee River MFL compliance record, dating back to when the MFL was adopted in September 2001. The District maintains a historical record of MFL monitoring data and reviewed it to determine if the single-day exceedance salinity criterion was exceeded before the 30-day moving average criterion. The compliance record showed five exceedance events of the single-day salinity criterion have occurred. However, the compliance record also showed that the 30- day moving average salinity criterion had already been exceeded before the five events occurred. In other words, the single-day criterion was never exceeded before the 30-day moving average criterion. Based on this evaluation, the District eliminated the single-day exceedance salinity criterion because it did not provide any additional resource protection. The District's decision was not arbitrary or capricious. 2. Not Using the Latest Model Evaluation of recommended MFL criteria and a recovery strategy for the CRE were greatly aided by integration of a suite of hydrologic and ecological models simulating (1) long-term fresh water inflow associated with varying management options, (2) the resulting salinity in the estuary, and (3) ecological response of indicator species that are sensitive to low fresh water inflows. Five models were specifically utilized, including three models for simulations of fresh water inflows to the CRE, a three-dimensional hydrodynamic salinity model, and a Vallisneria model. The three models simulating fresh water inflows included (1) the South Florida Water Management Model (SFWMM) to simulate fresh water discharges at S-79, which includes regional operations of Lake Okeechobee and incorporates Caloosahatchee River irrigation demands; (2) the C-43 Reservoir Model, which uses the SFWMM-simulated daily S-79 flow as input and simulates the management benefit of the C-43 Reservoir; and (3) the Watershed (WaSh) Model to simulate tidal tributary inflow from the Tidal Caloosahatchee Basin sub-watershed. The Caloosahatchee Hydrodynamic/Salinity Model was based on the Curvilinear Hydrodynamic Three-dimensional Model (CH3D) modeling framework with the functionality of simulating the spatial salinity structure across the entire estuary. The Vallisneria Model took the CH3D modeled salinity as input to simulate Vallisneria growth at critical locations in the estuary. The District did review the more recent Environmental Fluid Dynamic Code (EFDC) model developed for the Caloosahatchee Total Maximum Daily Load (TMDL) and being used by the Department of Environmental Protection. The District's expert witness, Dr. Detong Sun, testified that until 2014, the hydrodynamic part of the EFDC model was not working well. He testified that in 2016, the District still had concerns and suggested the use of the District's continuous monitoring data from seven locations across the CRE rather than grab samples for model calibration. Dr. Sun's opinion was that the EFDC model has improved in recent years, but was still behind the CH3D model in terms of performance. The District's expert witness, Dr. Amanda Kahn, testified that the water quality component of the EFDC model was not appropriate for this re-evaluation because the MFL is about water quantity, not water quality. The water quality component of the EFDC model addresses nutrient loadings, not minimum flows. Dr. Kahn also testified that in setting MFL criteria for the CRE, salinity was not a water quality component. Salinity was used as a water quantity component because it does not change with biological processes and can be a measure of how much fresh water is coming into the system. Based on a preponderance of the evidence, the District's decision not to use the EFDC model was not arbitrary or capricious. 3. Seasonality The Petitioners and Intervenors argued that the District is required to set an MFL that varies by season. For the CRE, the District set MFL criteria that protect the system from low flow that would occur in either the wet or dry season. As previously found, the re-evaluation studies focused on the dry season for two reasons: first, because it is well-established that the upstream migration of salt combined with reduced fresh water inflow alters the health and productivity of estuarine habitats; and second, because the dry seasons are the times when the current MFL criteria are likely to be exceeded or violated. The MFL statute states that "when appropriate, [MFLs] may be calculated to reflect seasonal variations." § 373.042(1)(b), Fla. Stat. The preponderance of the evidence showed that for the CRE, it was not necessary to set an MFL that varied by season. Improper Purpose The Petitioners, Sanibel, Cape Coral, and the Town, did not participate in this proceeding primarily to harass or to cause unnecessary delay or for frivolous purpose or to needlessly increase the cost of litigation. The Petitioners did not participate in this proceeding for an improper purpose. The Intervenors, Fort Myers, Estero, Bonita Springs, and CCP, did not participate in this proceeding primarily to harass or to cause unnecessary delay or for frivolous purpose or to needlessly increase the cost of litigation. The Intervenors did not participate in this proceeding for an improper purpose.
The Issue The issue in this case is whether the portion of Consumptive Use Permit (CUP) Application Number 97106 seeking an allocation of 499,000 gallons per day (gpd) of groundwater for commercial/industrial uses (supply bulk water to bottling plants) meets the conditions for issuance as established in Section 373.223, Florida Statutes, Florida Administrative Code Rule 40C-2.301, and the Applicant’s Handbook, Consumptive Uses of Water.1 The County does not oppose or contest the portion of the CUP application authorizing use of 6.0 million gpd of surface water for limerock mining operations.
Findings Of Fact The Parties The County is a political subdivision of the State of Florida. The County operates a water supply utility that supplies water for a variety of uses, including providing untreated water, in bulk, for bottling purposes. The County is currently engaged in a long-range planning effort designed to assess water supply demands and sources to supply those demands in the County over the next 50 years. The County also has completed a study of the two major springs in the County (Rainbow Springs and Silver Springs), and the County’s Board of County Commissioners is in the process of enacting certain recommendations contained in the study. The well for the proposed CUP allocation is located on approximately 160 acres in northern Marion County. Hastings and Greene's father owned the property from 1978 until the latter's death. In 1993, the latter's interest was transferred to Greene and two brothers, who now hold title to the property along with Hastings. The District is a special taxing district created by Chapter 373, Florida Statutes, and is charged with the duty to prevent harm to water resources of the District, and to administer and enforce Chapter 373, Florida Statutes, and the rules promulgated thereunder. The District has implemented Chapter 373, Florida Statutes, in part, through the adoption of Rule Chapters 40C-2 and 40C-20, and the Applicant’s Handbook, Consumptive Uses of Water. Historic Uses of Water on the Mine Site Since the 1980s, the property where the proposed withdrawals will occur has been used for mining of limerock and has been known as the “Black Sink Mine." A ten-inch diameter well has been located on the Black Sink Mine property for 35 years. The well was originally used to provide water to augment water levels in canals in and around the Black Sink Mine property. Later the well was used to irrigate watermelons grown on the property before the mining operation began. The limerock mining operation at Black Sink Mine uses approximately 6 million gpd of surface water. The mine pit at the site is divided by an earthen berm that separates a larger, previously mined area from a smaller area where active mining is occurring. Surface water is pumped from the actively mined portion of the pit to the larger, previously mined portion of the pit, to enable mining of the limerock material to be conducted at levels below the water table. Dewatering is necessary in order to remove the limerock. A majority of the property is mined to a depth of 55 feet below land surface. The limerock material extracted from the site is transported by trucks from the site, approximately 100 trucks per day, to various sites across North Florida. The Need for the Proposed Use of Groundwater If mining of limerock continues at the current pace, the limerock material at the Black Sink Mine will be exhausted within a year. Recognizing that the productive use of the property for limerock mining was nearing an end, Greene and Hastings began exploring other potential uses for the property, including use of the existing well on the property for production of bottled water. To explore the feasibility of producing water for bottling from the existing well, in 2004 Greene and Hastings engaged an engineering firm with expertise in water resources to conduct a hydrogeologic study of the mine property and well. The results of the study, showing water of sufficient quality and quantity for production of bottled water, motivated Greene and Hastings to submit the CUP application which was the subject of the hearing. The study also determined that water withdrawn from the well could be marketed as spring water. Greene and Hastings also determined through market research that the demand for bottled water has increased at the rate of ten percent per year for the last 4-5 years and that Florida bottlers were interested in purchasing water from the well on the mine site in bulk for bottling. In order to provide reasonable assurance that the water use proposed by Greene and Hastings is in such quantity as is necessary for economic and efficient utilization, Greene and Hastings must show that the amount to be used is consistent with what would typically be required for the activity being supplied; that the water will be used efficiently with loss or waste minimized; and that there is a demonstrated need for the water proposed for allocation. To demonstrate a need for the 499,000 gpd of groundwater requested in the application for an allocation of 499,000 gpd of groundwater, Greene and Hastings provided letters from two businesses engaged in bottling of water stating an intent to purchase specific quantities of water produced from the Greene and Hastings well should the CUP be granted. One of the letters of intent came from a bottler in Jacksonville, Florida, stating its intention to initially purchase 100,000 gpd of Greene and Hastings’s water. The other was from a bottler in Stuart, Florida, dated January 9, 2006, stating its intention to purchase 125,000 gpd of water from Greene and Hastings within “the next 12-24 months.” Based on these letters Greene and Hastings initially requested an allocation of 200,000 gpd of groundwater for the first year of the permit. Prior to completion of the CUP application, Greene and Hastings learned that because the Stuart bottler’s facility was located outside the geographic boundaries of the District, to transport water from the Black Sink Mine to the Stuart facility would require additional data and information related to inter- district transfers of groundwater. Greene and Hastings elected to reduce the requested allocation for the first year of the permit to 100,000 gpd, relying on the letter from the Jacksonville bottler. Based on the current market demand for bottled water, and based on the fact that there are other bottlers of water within the boundaries of the District purchasing water for bottling, it is reasonable to conclude that Greene and Hastings can sell 499,000 gpd of water from the well on the Black Sink Mine property by the end of the fifth year of the proposed CUP. These facts support the conclusion that there is a need for the amount of water requested by Greene and Hastings. In addition, the permit is conditioned to require a compliance review at five-year intervals during the term of the permit. Should Greene and Hastings not be successful in selling the full 499,000 gpd allocated by the fifth year of the permit, the District has the ability as part of the five-year compliance review to modify the permit to reduce the allocation based on the amount of water actually used for bottled water. Efficiency of the Proposed Use of Water The production of water in bulk for shipment to a bottler is a highly efficient use of water. There is very little if any water lost in the withdrawal and loading of the water; almost all the water goes to the end product. The evidence establishes that the use proposed by Greene and Hastings is an efficient use of water. Potential Impacts from the Proposed Groundwater Allocation The source of the groundwater proposed for use by Greene and Hastings is the Floridan aquifer. Because there is no confining layer in the vicinity of the Black Sink Mine that would retard movement of water between the Upper Floridan aquifer and the surficial aquifer, both the Upper Floridan aquifer and the surficial aquifer essentially behave as one unit. Thus, any drawdown in the surficial aquifer associated with groundwater withdrawals at this location will be the same as the related drawdown in the Upper Floridan aquifer as a result of groundwater withdrawals. The Floridan aquifer is capable of producing the amount of groundwater requested by Greene and Hastings in the application. To assess the level of drawdown expected to occur in both the Floridan aquifer and the surficial aquifer as a consequence of the proposed groundwater withdrawals, Greene and Hastings engaged a consultant, Andreyev Engineering, Inc., to run a groundwater model to simulate the proposed withdrawal and predict the anticipated drawdown. The groundwater model selected for use for this application was the North Central Florida Regional Groundwater Flow Model, a model developed for the District by the University of Florida for use in Marion County and surrounding areas. This model is an accepted and reliable tool for predicting aquifer drawdown associated with groundwater withdrawals at the location of the withdrawals proposed in this application and is used extensively by the District in its CUP program. To simulate the drawdown associated with the withdrawal of 499,000 gpd from the Florida aquifer, Greene and Hastings’s consultant inserted a pumping well in the model grid where the Black Sink Mine is located. The model then simulated pumping from the well at 499,000 gpd. The model results are graphically depicted on maps showing drawdown contours overlain on the Black Sink Mine Site, illustrating the level of drawdown in the aquifer and the distance the level of drawdown extends out from the well site. The model predicts a drawdown of 0.03 feet in the Floridan and surficial aquifers in the immediate vicinity of the well on the Black Sink Mine property, and a drawdown of 0.02 feet in the Floridan and surficial aquifers extending out to a distance of approximately 5,000 feet from the well, less than 1/3 of an inch of drawdown. The model results represent a reasonable estimation of the drawdown that will occur as a consequence of withdrawal of 499,000 gpd of groundwater at the Black Sink Mine as proposed in the application. The impact of the 0.02-0.03 foot drawdown predicted by the model was variously characterized by the experts who testified at the final hearing as “not practically measurable,” an “insignificant impact,” “very small,” or “de minimus.” The use of water proposed by Greene and Hastings will not cause significant saline water intrusion, nor will it further aggravate any existing saline water intrusion problems. The use of water proposed by Greene and Hastings will not induce significant saline water intrusion to such an extent as to be inconsistent with the public interest. Because the predicted drawdown is so small, it will not interfere with any existing legal uses of water. Neither will the predicted drawdown cause serious harm to the quality of the source of the water proposed for use by Greene and Hastings. With regard to the issue of interference with existing legal users, the County argued that the District should have considered whether there is sufficient groundwater available to meet all projected needs for water in the County during the 20- year term of the permit, as well as the additional cost County citizens will need to bear to secure alternative water supplies as a result of any future shortfalls in available groundwater. The County projects, based on planning estimates, that use of groundwater to supply all anticipated uses of water in the County will be limited within 20-30 years from the present. Such “limits” would not become an issue until after the Greene and Hastings permit expires. Thereafter, water users in the County will have to rely on alternative water sources, conservation, reuse of reclaimed water, and surface water. The anticipated growth in demand in the County’s planning estimates includes anticipated growth in the commercial/industrial category of uses. The County’s estimated limits on groundwater use will occur whether or not the CUP requested by Greene and Hastings is approved. The District does not base its permitting decisions on a pending CUP application on the possibility that the source of water may become limited at some future time for water uses not presently permitted, provided the application meets all permitting criteria. The District allocates water for recognized beneficial uses of water, such as commercial/industrial uses, as long as the water is available and the application meets District criteria. The District allocates water as long as an allocation does not cause harm to the resource. Based on these facts, the proposed use of water by Greene and Hastings will not interfere with any existing legal use of water. No Evidence of Economic or Environmental Harm Because the predicted drawdown associated with the proposed use of water is so small, and because no impacts are anticipated on any surrounding properties or water uses, Greene and Hastings have provided reasonable assurance that any economic harm caused by the proposed use has been reduced to an acceptable amount. For purposes of determining whether an applicant has provided reasonable assurance that any environmental harm caused by a proposed use of water is reduced to an acceptable amount, the District examines modeling results showing the level of drawdown predicted for the use and also examines the resources in and around the site of a withdrawal to determine the likely impact of the drawdown predicted for the withdrawal on those resources. The District’s environmental scientists examined the Black Sink Mine site and the surrounding landscape and determined that, based on the characteristics of the landscape in and around the site of the proposed withdrawal and based on the negligible drawdown impact predicted for the proposed water use in both the Floridan and surficial aquifers, there will be no environmental harm resulting from the allocation of groundwater contained in the CUP. The use of water proposed by Greene and Hastings will not cause damage to crops, wetlands, or other types of vegetation. The use of water proposed by Greene and Hastings will not cause the water table to be lowered so that stages or vegetation will be adversely and significantly affected on lands other than those owned, leased, or otherwise controlled by Greene and Hastings. The CUP will not use water that the District has reserved pursuant to Section 373.223(3), Florida Statutes, and Rule 40C-2.301(4). No Impact on Established Minimum Flows or Levels No minimum surface or groundwater levels or surface water flows have been established by the District pursuant to Rule Chapter 40C-8 for any of the water bodies in Marion County that may be affected by the proposed water use. The closest water body for which the District has established a minimum flow is the St. Johns River at the State Road 44 bridge located more than 50 miles from the Black Sink Mine property. The closest water body for which the District has established a minimum level is Star Lake in Northwest Putnam County, more than nine miles from the mine site. Because of the distance of these water bodies from the withdrawal site and because of the negligible drawdown expected to be caused by the proposed use of water, the use will not cause an established minimum flow or level to be exceeded during the term of the permit. Other Reasonable-Beneficial Use Considerations All available conservation measures that are economically, environmentally, and technically feasible are proposed for implementation in the application by Greene and Hastings for the uses proposed by them. Greene and Hastings submitted to the District, as part of the application, a conservation plan that complies with the requirements of A.H. Section 10.3(e). Reclaimed water, as defined in the District’s rules, is not currently available to be used in place of the water proposed for use by Greene and Hastings in the application. The use of water proposed by Greene and Hastings in the application will not cause or contribute to a violation of water quality standards in receiving waters of the state. The use of water proposed by Greene and Hastings in the application will not cause or contribute to flood damage. The Use is Consistent With the Public Interest With regard to the determination of whether reasonable assurance was provided that the proposed use is consistent with the public interest, the County contends that: 1) Greene and Hastings must show that any necessary approvals required by the County’s Comprehensive Plan and/or its LDRs for use of the site for producing bottled water have been obtained; 2) that the District did not properly consider the effect of existence of lawn watering restrictions affecting citizens in the County in evaluating the application; and 3) that the District should have considered the amount of money the applicant may stand to gain from the use of the water requested in the application. In examining whether an application is consistent with the public interest, the District considers whether a particular use of water is going to be beneficial or detrimental to the people of the area and to water resources within the state. In this inquiry, the District considers whether the use of water is efficient, whether there is a need for the water requested, and whether the use is for a legitimate purpose; and the inquiry focuses on the impact of the use on water resources and existing legal users. Sale of water for bottling for human consumption is recognized by the District as a legitimate, beneficial economic enterprise. Use of water for human consumption is among the highest and best uses permitted by the District. For reasons outlined above in the Recommended Order, there are no detrimental impacts that will result from this use of water. The District does not consider whether local government approvals have been obtained prior to issuance of a CUP for purposes of determining whether the application is consistent with the public interest. Neither does the District consider impacts related to local roads from trucks transporting the water or other impacts not related to water resources. No such requirements are included in the District’s adopted permitting criteria. There are no water shortage orders in effect in the District at present. In evaluating a CUP application, the District considers whether its permitting criteria will be met during periods of normal weather as well as during periods of drought. Withdrawals authorized in CUPs can be restricted by order of the District during periods of water shortage, such as droughts. Thus, the possibility of a water shortage order being entered in the County in the future, or the fact that such orders may have been in effect there in the past, does not mean the application is not consistent with the public interest. The District critically examines the efficiency of all water uses for purposes of enacting its regulatory requirements regarding CUPs and in evaluating CUP applications. The District has adopted restrictions on landscape irrigation (which apply to all such users throughout the District’s jurisdiction, not just in Marion County) limiting landscape irrigation to no more than two days per week. The limitations on landscape irrigation exist because this type of use has been determined to be a highly inefficient, wasteful use of water without such restrictions. By contrast, the use of water proposed by Greene and Hastings is a highly efficient use of water, resulting in little or no loss or waste of water. The District does not consider the level of financial gain or benefit an applicant will derive from a permitted use of water for purposes of determining whether the proposed use is consistent with the public interest. Most, if not all permitted users of water derive some level of economic benefit from the water they use, and the District’s rule criteria do not provide standards for evaluating such gain or that otherwise limit the amount of such gain. For the foregoing reasons, the Applicant has provided reasonable assurance that the use of water proposed in the application is consistent with the public interest. Groundwater is the Lowest Quality Source for this Use The County contends that groundwater is not the lowest quality source of water available for the use proposed by Greene and Hastings, in that surface water from the mine pit on the site could be treated and used for bottling in place of groundwater. From the testimony, it is clear that Greene and Hastings’s ability to market water for bottling from the Black Sink Mine is dependent on such water being capable of being labeled as spring water, and on such water being delivered without having gone through any treatment processes. The testimony also establishes that because of the connection between the surficial aquifer and the Upper Floridan aquifer at the site, using surface water instead of groundwater to supply the proposed use would result in little if any reduction in impacts to the Floridan aquifer. More importantly, because the application proposes use of water for direct human consumption, the District’s rules do not require use of a lower quality source of water. For the foregoing reasons, groundwater is the lowest quality source of water suitable for use for bottled water for human consumption. The District’s Noticing Was Adequate and Appropriate The District provided notice of its receipt of the Greene and Hastings CUP application by publishing notice in the Ocala Star-Banner, a newspaper of general circulation in Marion County, on January 25, 2005, with an amended notice being published on February 16, 2005, and also by letters to the County dated January 20, 2005, and February 10, 2005. In each notice, the location of the proposed use was identified by section, township, and range. The County responded to the notices by sending a letter of objection to the application dated February 14, 2005. Thus, the County received sufficient information regarding the location of the proposed use to enable it to prepare and file a letter of objection to the application, and suffered no prejudice as a consequence of the notice. The District provided personal notice of its intent to issue a CUP to Greene and Hastings by letter dated April 5, 2006. In this notice, the location of the proposed use was identified by section, township, and range. The County responded by filing petitions that have resulted in this proceeding. Thus, the County received sufficient notice of the location of the use addressed in the District’s intent to issue to enable it to initiate administrative proceedings regarding the permit, and suffered no prejudice as a consequence of the notice.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the District enter an order granting CUP No. 97106 to Greene and Hastings with the conditions recommended in the District’s Technical Staff Report. DONE AND ENTERED this 9th day of January, 2007, in Tallahassee, Leon County, Florida. S J. LAWRENCE JOHNSTON Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 9th of January, 2007.
The Issue The issues to be resolved in this proceedings concern whether Environmental Resource Permit (ERP) No. 4-109-0216-ERP, should be modified to allow construction and operation of a surface water management system (project) related to the construction and operation of single-family homes on "Marshall Creek" (Parcel D) in a manner consistent with the standards for issuance of an ERP in accordance with Rules 40C-4.301 and 40C-4.302, Florida Administrative Code.
Findings Of Fact The Project The project is a 29.9-acre residential development and associated stormwater system in a wetland mitigation area known as "Parcel D." It lies within the much larger Marshall Creek DRI in St. Johns County, Florida, bounded on the northeast by Marshall Creek, on the south and southeast by a previously permitted golf course holes sixteen and seventeen, and on the north by the "Loop Road." The project consists of thirty residential lots of approximately one-half acre in size; a short segment of Loop Road to access Parcel D; an internal road system; expansion of previously permitted Pond N, a wet detention stormwater management pond lying north of the Loop Road and wetland mitigation areas. Approximately 1.15 acres of wetlands are located on the Parcel D site. The project plan calls for filling 0.63 acres of the wetlands for purposes of constructing a road and residential lots for Parcel D. Part of that 0.63-acre impact area, 0.11 acres, is comprised of a 760-foot-long, narrow drainageway, with 0.52 acres of adjacent wetland. Downstream of the fill area, 0.52 acres of higher quality wetland is to be preserved. Hines proposes to preserve 4.5 acres of existing wetland and 2.49 acres of upland, as well as to create .82 acres of forested wetland as mitigation for the proposed impact of the project. Additionally, as part of the project, Hines will implement a nutrient and pesticide management plan. The only pesticides to be used at the project will be approved by the Department of Agriculture for use with soil types prevailing at the site and only pesticides approved by the Environmental Protection Agency may be used on the site. All pesticides to be used on the project site must be selected to minimize impacts to ground and surface water, including having a maximum 70-day half-life. Stormwater Management System The majority of surface runoff from Parcel D will be diverted to a stormwater collection system and thence through drainage pipes and a swale into Phase I of Pond N. After treatment in Pond N, the water will discharge to an upland area adjacent to wetlands associated with Marshall Creek and then flow into Marshall Creek. The system will discharge to Marshall Creek. In addition to the area served by Pond N, a portion of lots fourteen though twenty drain through a vegetated, natural buffer zone and ultimately through the soil into Marshall Creek. Water quality treatment for that stormwater runoff will be achieved by percolating water into the ground and allowing natural soil treatment. The fifty-foot, vegetated, natural buffer is adequate to treat the stormwater runoff to water quality standards for Lots 14, 15 and 20. Lots 16, 17, 18 and 19, will have only a twenty-five foot buffer, so additional measures must be adopted for those lots to require either that the owners of them direct all runoff from the roofs and driveways of houses to be constructed on those lots to the collection system for Pond N or placement of an additional twenty-five foot barrier of xeriscape plants, with all non- vegetated areas being mulched, with no pesticide or fertilizer use. An additional mandatory permit condition, specifying that either of these measures must be employed for Lots 16, 17, 18 and 19, is necessary to ensure that water quality standards will be met. Pond N is a wet detention-type stormwater pond. Wet detention systems function similarly to natural lakes and are permanently wet, with a depth of six to twelve feet. When stormwater enters a wet detention pond it mixes with existing water and physical, chemical and biological processes work to remove the pollutants from the stormwater. Pond N is designed for a twenty-five year, twenty-four- hour storm event (design storm). The pre-development peak rate of discharge from the Pond N drainage area for the design storm event is forty cubic feet per second. The post-development peak rate of discharge for the design storm event will be approximately twenty-eight cubic feet per second. The discharge rate for the less severe, "mean annual storm" would be approximately eleven cubic feet per second, pre-development peak rate and the post-development peak rate of discharge would be approximately five cubic feet per second. Consequently, the post-development peak rate of discharge does not exceed the pre- development peak rate of discharge. Pond N is designed to meet the engineering requirements of Rule 40C-42.026(4), Florida Administrative Code. Because the pond is not designed with a littoral zone, the permanent pool volume has been increased by fifty-percent. Additionally, because Pond N discharges to the Class II waters of Marshall Creek, an additional fifty-percent of treatment volume is included in the pond design. The system design addresses surface water velocity and erosion issues through incorporation of best management practices promulgated by the District to prevent erosion and sedimentation, including; designing side slopes of 4:1; siding and seeding disturbed areas to stabilize soil; and the use of riprap at the outfall from Pond N. During construction, short- term water quality impacts will be addressed through installation of silt fences and hay bales. The majority of the eighteen-acre drainage basin which flows into the Parcel D wetland lies to the south and southwest of Parcel D. In accordance with the prior permit, water from those off-site acres will be intercepted and routed to stormwater ponds serving golf course holes sixteen and seventeen. The system design will prevent adverse impacts to the hydroperiod of remaining on-site and off-site wetlands. The remaining wetlands will be hydrated through groundwater flow. Surface waters will continue to flow to the wetlands adjacent to lots fourteen through twenty because drainage from those lots will be directed across a vegetated, natural buffer to those wetlands. There is no diversion of water from the natural drainage basin, because Pond N discharges to a wetland adjacent to Marshall Creek, slightly upstream from the current discharge point for the wetland which is to be impacted. This ensures that Marshall Creek will continue to receive that fresh-water source. An underground "PVC cut-off wall" will be installed around Pond N to ensure that the pond will not draw down the water table below the wetlands near the pond. Pond N has been designed to treat stormwater prior to discharge, in part to remove turbidity and sedimentation. This means that discharge from the pond will not carry sediment and that the system will not result in shoaling. There will be no septic tanks in the project. The system is a gravity flow system with no mechanical or moving parts. It will be constructed in accordance with standard industry materials readily available and there will be nothing extraordinary about its design or operation. The system is capable of being effectively operated and maintained and the owner of the system will be the Marshall Creek Community Development District (CDD). Water Quality Water entering Pond N will have a residence time of approximately 200 days or about fifteen times higher than the design criteria listed in the below-cited rule. During that time, the treatment and removal process described herein will occur, removing most of the pollutants. Discharge from the pond will enter Marshall Creek, a Class II water body. The discharges must therefore meet Class II water quality numerical and anti-degradation standards. The design for the pond complies with the design criteria for wet detention systems listed in Rule 40C-42.026(4), Florida Administrative Code. In addition to meeting applicable design criteria, the potential discharge will meet water quality standards. The pond will have low levels of nitrogen and phosphorous resulting in low algae production in the pond. The long residence time of the water in the pond will provide an adequate amount of time for pesticides to volatilize or degrade, minimizing the potential for pesticide discharge. Due to the clear characteristics of the water column, neither thermal stratification nor chemical stratification are expected. Periodically, fecal coliform and total coliform levels are exceeded under current, pre-development conditions. These are common natural background conditions. Because the detention time in the pond will be an average of 200 days, and because the life span of fecal coliform bacteria is approximately seven to fourteen days the levels for coliforms in the pond will be very low. Discharges from the pond will enhance water quality of the Class II receiving waters because the levels of fecal coliform and total coliform will be reduced. The discharge will be characterized by approximately 100 micrograms per liter total nitrogen, compared with a background of 250 micrograms per liter presently existing in the receiving waters of Marshall Creek. The discharge will contain approximately three micrograms per liter of phosphorous, compared with sixty-three micrograms per liter presently existing in Marshall Creek. Total suspended solids in the discharge will be less than one-milligram per liter compared with seventy-two milligrams per liter in the present waters of Marshall Creek. Biochemical oxygen demand will be approximately a 0.3 level in the discharge, compared with a level of 2.4 in Marshall Creek. Consequently, the water quality discharging from the pond will be of better quality than the water in Marshall Creek or the water discharging from the wetland today. The pollutant loading in the discharge from the stormwater management system will have water quality values several times lower than pre-development discharges from the same site. Comparison of pre-development and post-development mass loadings of pollutants demonstrates that post-development discharges will be substantially lower than pre-development discharges. Currently, Marshall Creek periodically does not meet Class II water quality standards for dissolved oxygen. Construction and operation of the project will improve water quality in the creek concerning dissolved oxygen values because discharges from Pond N will be subjected to additional aeration. This results from design features such as discharge from the surface of the system, where the highest level of dissolved oxygen exists, and the discharge water draining through an orifice and then free falling to a stormwater structure, providing additional aeration. Discharges from the system will maintain existing uses of the Class II waters of Marshall Creek because there will be no degradation of water quality. Discharges will not cause new violations or contribute to existing violations because the discharge from the system will contain less pollutant loading for coliform and will be at a higher quality or value for dissolved oxygen. Discharges from the system as to water quality will not adversely affect marine fisheries or marine productivity because the water will be clear so there will be no potential for thermal stratification; the post-development discharges will remain freshwater so there will be no change to the salinity regime; and the gradual pre-development discharges will be replicated in post-development discharges. Several factors minimize potential for discharge of pesticide related pollutants: (1) only EPA-approved pesticides can be used; (2) only pesticides approved for site-specific soils can be used; (3) pesticides must be selected so as to minimize impacts on surface and groundwater; (4) pesticides must have a maximum half-life of 70 days; and (5) the system design will maximize such pollutant removal. Archaeological Resources The applicant conducted an archaeological resource assessment of the project and area. This was intended to locate and define the boundaries of any historical or archaeological sites and to assess any site, if such exists, as to its potential eligibility for listing in the National Register of Historic Places (National Register). Only a portion of one archaeological site was located on the project tract. Site 8SJ3473, according to witness Anne Stokes, an expert in the field of archaeological assessment, contains trace artifacts dating to the so-called "Orange Period," a time horizon for human archaeological pre-history in Florida dating to approximately 2,300 B.C. The site may have been only a small campsite, however, since only five pottery fragments and two chert flakes, residuals from tool-making were found. Moreover, there is little possibility that the site would add to knowledge concerning the Orange Period or pre-history because it is a very common type of site for northeast Florida and is not an extensive village site. There are likely other campsites around and very few artifacts were found. No artifacts were found which would associate the site with historic events or persons. The applicant provided the findings of its cultural resource assessment, made by Dr. Stokes, to the Florida Division of Historical Resources. That agency is charged with the responsibility of reviewing cultural resource assessments to determine if significant historic or archaeological resources will be impacted. The division reviewed the survey techniques used by Dr. Stokes, including shovel testing, sub-surface testing and pedestrian walk-over and investigation. The division determined that the site in question is not of a significant historical or archaeological nature as a resource because it does not meet any of the four criteria for inclusion in the National Register.1 Thus the referenced agency determined that the site in question is not a significant historical or archaeological resource and that construction may proceed in that area without further investigation, insofar as its regulatory jurisdiction is concerned. Wetlands The wetlands to be impacted by the project consist of a 1,000 foot drainage-way made up of a 0.11 acre open-water channel, approximately four feet wide, and an adjacent vegetated wetland area of approximately 0.52 acres containing fewer than 30 trees. The open-water channel is intermittent in that it flows during periods of heavy rainfall and recedes to a series of small, standing pools of water during drier periods. The Parcel D wetland is hydrologically connected to Marshall Creek, although its ephemeral nature means that the connection does not always flow. The wetland at times consists only of isolated pools that do not connect it to Marshall Creek. Although it provides detrital material export, that function is negligible because the productivity of the adjacent marsh is so much greater than that of the wetland with its very small drainage area. Because of the intermittent flow in the wetland, base flow maintenance and nursery habitat functions are not attributed to the wetland. The Parcel D wetland is not unique. The predominant tree species and the small amount of vegetated wetland are water oak and swamp bay. Faunal utilization of the wetland is negligible. The wetland drainage-way functions like a ditch because it lacks the typical characteristics of a creek, such as a swampy, hardwood floodplain headwater system that channelizes and contains adjacent hardwood floodplains. The location of the wetland is an area designated by the St. Johns County comprehensive plan as a development parcel. The Florida Natural Areas Inventories maps indicate that the wetland is not within any unique wildlife or vegetative habitats. The wetland is to be impacted as a freshwater system and is not located in a lagoon or estuary. It contains no vegetation that is consistent with a saltwater wetland. The retaining wall at the end of the impact area is located 1.7 feet above the mean high water line. Wetland Impacts The proposed 0.63 acre wetland impact area will run approximately 760 linear feet from the existing trail road to the proposed retaining wall. If the wetland were preserved, development would surround the wetland, adversely affecting its long-term functions. Mitigation of the wetland functions is proposed, which will provide greater long-term ecological value than the wetland to be adversely affected. The wetland to be impacted does not provide a unique or special wetland function or good habitat source for fish or wildlife. The wetland does not provide the thick cover that would make it valuable as Black Bear habitat and is so narrow and ephemeral that it would not provide good habitat for aquatic-dependent and wetland-dependent species. Its does not, for instance, provide good habitat for woodstorks due to the lack of a fish population and its closed- in tree canopy. Minnow sized fish (Gambusia) and crabs were seen in portions of the wetland, but those areas are downstream of the proposed area of impact. Mitigation Mitigation is offered as compensation for any wetland impacts as part of an overall mitigation plan for the Marshall Creek DRI. The overall mitigation plan is described in the development order, the mitigation offered for the subject permit and mitigation required by prior permits. A total of 27 acres of the more than 287 acres of wetlands in the total 1,300-acre DRI tract are anticipated to be impacted by the DRI. Approximately 14.5 acres of impacted area out of that 27 acres has already been previously authorized by prior permits. The overall mitigation plan for the DRI as a whole will preserve all of the remaining wetlands in the DRI after development occurs. Approximately one-half of that preserved area already has been committed to preservation as a condition of prior permits not at issue in this case. Also, as part of prior permitting, wetland creation areas have been required, as well as preserved upland buffers which further protect the preserved wetlands. The mitigation area for the project lies within the Tolomato River Basin. The development order governing the total DRI requires that 66 acres of uplands must also be preserved adjacent to preserved wetlands. The overall mitigation plan for the DRI preserves or enhances approximately 260 acres of wetlands; preserves a minimum of 66 acres of uplands and creates enhancement or restores additional wetlands to offset wetland impacts. The preserved wetlands and uplands constitute the majority of Marshall Creek, and Stokes Creek which are tributaries of the Tolomato River Basin, a designated Outstanding Florida Water (OFW). Preservation of these areas prevents them from being timbered and ensures that they will not be developed in the future. The overall DRI mitigation plan provides regional ecological value because it encompasses wetlands and uplands they are adjacent to and in close proximity to the following regionally significant resources: (1) the 55,000 acre Guana- Tolomato-Matanzas National Estuarine Research Reserve; (2) the Guana River State Park; (3) the Guana Wildlife Management Area; (4) an aquatic preserve; (5) an OFW; and (6) the 22,000 acre Cummer Tract Preserve. The mitigation plan will provide for a wildlife corridor between these resources, preserve their habitat and insure protection of the water quality for these regionally significant resources. The mitigation offered to offset wetland impacts associated with Parcel D includes: (1) wetland preservation of 0.52 acres of bottom land forest along the northeast property boundary (wetland EP); (2) wetland preservation of 3.98 acres of bottom land forest on a tributary of Marshall Creek contained in the DRI boundaries (Wetlands EEE and HHH); (3) upland preservation of 2.49 acres, including a 25-foot buffer along the preserved Wetlands EEE and HHH and a 50-foot buffer adjacent to Marshall Creek and preserved Wetland EP; (4) a wetland creation area of 0.82 acres, contiguous with the wetland preservation area; and (5) an upland buffer located adjacent to the wetland creation area. The wetland creation area will be graded to match the grades of the adjacent bottomland swamp and planted with wetland tree species. Small ponds of varying depths will be constructed in the wetland creation area to provide varying hydrologic conditions similar to those of the wetland to be impacted. The wetland creation area is designed so as to not de-water the adjacent wetlands. All of the mitigation lands will be encumbered with a conservation easement consistent with the requirements of Section 704.06, Florida Statutes. The proposed mitigation will offset the wetland functions and values lost through the wetland impact on Parcel D. The wetland creation is designed to mimic the functions of the impact area, but is located within a larger ecological system that includes hardwood wetland headwaters. The long-term ecological value of the mitigation area will be greater than the long-term value of the wetland to be impacted because; (1) the mitigation area is part of a larger ecological system; (2) the mitigation area is part of an intact wetland system; (3) the wetland to be impacted will be unlikely to maintain its functions in the long-term; and (4) the mitigation area provides additional habitat for animal species not present in the wetland to be impacted. Certain features will prevent adverse secondary impacts in the vicinity of the roadway such as: (1) a retaining wall which would prevent migration of wetland animals onto the road; (2) a guard rail to prevent people from moving from the uplands into wetlands; and (3) a vegetated hedge to prevent intrusion of light and noise caused by automotive use of the roadway.
Recommendation Having considered the foregoing Findings of Fact and Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is RECOMMENDED: That a final order be entered granting the subject application for modification of Permit 4-109-0216A-ERP so as to allow construction and operation of the Parcel D project at issue, with the addition of the inclusion of a supplemental permit condition regarding the vegetated natural buffers for Lots 16 through 19 described and determined above. DONE AND ENTERED this 9th day of April, 2001, in Tallahassee, Leon County, Florida. P. MICHAEL RUFF Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 9th day of April, 2001.
The Issue The issue in this case is whether the St. Johns River Water Management District (District) should issue a consumptive use permit (CUP) in response to Application Number 99052 filed by the City of Titusville and, if so, what CUP terms are appropriate.
Findings Of Fact Area II and III Wellfields On February 10, 1998, the District issued CUP 10647 to the City of Titusville, authorizing the withdrawal of an annual average of 6.5 mgd from the City's Area II and Area III Wellfields, 5.4 from Area II and 1.1 from Area III. These wellfields are owned and operated by the City and are located within its municipal boundaries. They produce water from the SAS. The Area II Wellfield is located near I-95 in the northeastern portion of the City and consists of shallow wells primarily constructed between 1955 and 2002. It consists of 53 production wells, of which 31 are considered to be of primary use. The City replaced 16 Area II production wells in 1995 and 4 production wells in 2000 and is currently considering the replacement of 4 additional wells. The Area III Wellfield is located in the south-central portion of the City’s service area. It consists of 35 production wells, of which 18 are considered to be of primary use. Petitioners contend that both the "safe yield" (the quantity of water the City can withdraw without degrading the water resource) and the "reliable yield" (the quantity of water the City can dependably withdraw) of the Area II and III Wellfields are the permitted limits of 5.4 and 1.1 mgd, respectively. The City and the District contend that saline intrusion into the SAS has reduced the safe and reliable yields to significantly less than the permitted amounts at this time. Historically, the Area II Wellfield was the most productive wellfield. Prior to 1988, the City relied entirely on the Area II Wellfield and pumped almost 5 mgd from it at times. Since then, several Area II wells have shown signs of water quality degradation that has resulted in a reduction in pumping to better stabilize water quality levels. For the past five years, the City has only pumped approximately 3 mgd on an annual average basis from the Area II Wellfield. Chloride concentrations exceeding 250 mg/l have been recorded in 16 Area II production wells. Chloride concentrations exceeding 250 mg/l have been recorded in 22 Area III production wells. About 10 wells in the Area II and III Wellfields have been abandoned because of water quality degradation. At the Area II Wellfields there are 10 wells whose use is impaired because of water quality issues. At the Area III Wellfields there are 15 wells whose use is impaired because of water quality issues. Area III has had serious chloride problems, with concentrations at or near 200 mg/l for much of the mid-90's. In the Area III Wellfield, the Anastasia wells have the best water quality. However, these wells have also seen increasing concentrations of chlorides, with one well over 200 mg/l. According to information introduced into evidence by the City, it appears that Area III began to have chloride problems primarily due to over-pumping.5 The City pumped far in excess of permit limits from Area III during the early 1990's, including almost twice the permit limit in 1990 and 1.5 times the limit in 1991. While chlorides were between 77 and 92 mg/l in 1990-92, they began to rise in 1993 and were between 192 and 202 mg/l for the rest of the decade. Area III production declined in 1997 to approximately 0.66 mgd and declined further to a low of approximately 0.5 mgd in 1999. In 2000, chlorides fell to approximately 138 mg/l and then rose to approximately 150 mg/l in 2002-04, while production gradually rose to close to the permit limit in 2002 and 2003, before dipping to 0.75 mgd in 2004. In 2005, production was back up to 1 mgd, and chlorides were approximately 87 mg/l. During the five years from 2001 through 2005, the City has pumped an annual average rate of approximately 1 mgd from Area III. In contrast, Area II has not been over-pumped during the same time period. Area II production generally declined from a high of 4.146 mgd in 1992 to a low of 2.525 mgd in 2000, except for an increase of approximately 0.25 mgd between 1997 and 1998. During this time, chlorides generally declined from a high of 124 mg/l in 1993 to approximately 68 mg/l in 2000, with the exception of a rise to approximately 111 mg/l in 1999. Area II production then generally increased through 2003 to approximately 3.000 mgd, where it remained in 2004 before declining to approximately 2.770 mgd in 2005. Area II chlorides were approximately 113 mg/l in 2001, 109 in 2002, 86 in 2003, 76 in 2004, and 83 in 2005. During the five years from 2001 through 2005, the City has pumped only an annual average rate of 2.86 mgd. In 1995, the City entered into a contract with the City of Cocoa requiring the City to pay for at least 1 mgd each year, whether the City actually takes the water or not (the "take-or-pay" clause). Using the Cocoa water allowed the City to reduce production from Area III without a corresponding increase in production from Area II. Water conservation measures implemented since 1998, including conservation rates, have since reduced per capita water use. In 2002, the contractual take-or-pay requirement was reduced to 0.5 mgd. After 2002, purchases of Cocoa water have amounted to 0.576, 0.712, and 0.372 mgd on an annual average basis. As a result, since at least 1990 Area II has not been required to produce at its permitted limit. It is not clear exactly what the City believes to be safe and reliable yields at this time from Areas II and III. In its PRO, the City took the position that the total reliable yield is 3.5 to 4 mgd, of which 2.25 to 2.5 mgd is attributable to the Area II Wellfield and 0.75 mgd is attributable to the Area III Wellfield. However, its consultant, Mr. Patrick Barnes, testified that the City's current reliable yields are 3 mgd from Area II and 1 or 1.1 mgd from Area III. He testified that the safe yield from Area II would be approximately 3.5 mgd. The District has not formulated an opinion as to the exact of amount of water that can be produced from the Area II and III Wellfields on a sustainable basis. However, the District believes that recent production levels, which have resulted in a stabilization of chloride concentrations, may be the most production that can be sustained from these facilities without adverse water resource impacts. That would mean approximately 4.5 mgd on an annual average basis from Areas II and III combined. It might be possible for the City to expand the reliable yield of the Area II Wellfield by constructing additional wells or through some other measures. But Brevard County’s North Brevard Wellfield, located immediately north of the City’s Area II Wellfield, utilizes the same SAS used by the Area II Wellfield, and Brevard County recently received an increased permitted allocation from the District for this facility. This would limit the City’s ability to expand the current production of water from the Area II Wellfield. Other limitations on expansion of production from Areas II and III include: the relatively high risk of contamination of the SAS from pollution sources such as underground petroleum storage tanks; the limited space available in an increasingly urbanized area for the construction of new wells; the chronic bio-fouling and encrustation of wells due to the high iron content of the SAS; and the low specific capacity of each production well. For these reasons, it is not clear at this point in time whether it is possible to sustain more water production from Areas II and III than the City has pumped in recent years. B. Area IV Application and TSR On March 6, 2001, the City of Titusville submitted its application to modify CUP 10647. Included in this application was a proposal to add a new Area IV Wellfield in northwest Brevard County to pump up to 2.75 mgd from the UFAS. The District issued a series of seven Requests for Additional Information in between April 5, 2001, and March 23, 2004. On December 15, 2004, the District issued its initial TSR for the CUP modification application. That TSR proposed to authorize the use of 2.75 mgd from the UFAS and 0.18 mgd of groundwater from the SAS from the proposed Area IV Wellfield and 3.3 mgd of groundwater from the SAS from the existing Area II and Area III Wellfields to serve a projected population of 56,565 in 2008. There was no request to extend or renew the permit, which expires February 10, 2008. Miami Corporation filed a petition challenging this TSR. On May 13, 2005, the City submitted a revised application for a separate Individual CUP for the Area IV Wellfield, rather than modifying its existing CUP 10647 to include the new wellfield, with a permit expiration of December 31, 2010. On May 25, 2005, the staff issued a revised TSR. That TSR proposed a new permit to authorize up to 2.75 mgd of groundwater from the UFAS and 0.178 mgd of groundwater from the SAS from the proposed Area IV Wellfield to serve a projected population of 59,660 in 2010. The revised TSR noted that the proposed permit expiration date for the Area II and Area III Wellfields would remain February 10, 2008. Vergie Clark filed a petition challenging the revised TSR, as did Miami Corporation. After various notices on the TSR and the revised TSR to interested persons in Brevard County, in August 2005 the District issued additional notice to interested persons in Orange, Seminole and Volusia Counties. As a result, all required public notices have been issued. On March 14, 2006, the City again revised its application, and on May 1, 2006, the District issued its second revised, and final, TSR--which is the TSR now at issue. The TSR at issue recommended that a CUP be issued to Titusville for 2.75 mgd of groundwater from the UFAS and .18 mgd of groundwater from the SAS for wetland hydration and aquifer recharge from the Area IV Wellfield on an annual average basis to serve a projected population of 63,036 in 2010. This TSR provided that the proposed permit would expire December 31, 2010. TSR at Issue Water Use Allocation The CUP recommended by the TSR would only grant the City a water allocation from the Area IV Wellfield for 2009 and 2010. The recommended CUP would allow the City to withdraw water from the Area IV Wellfield at an annual average rate of 2.75 mgd during those years for public supply. (Other Condition 4) The CUP recommended by the TSR would limit the City’s potable water allocation from the Area IV Wellfield to a maximum rate of 3.85 mgd during the four consecutive months of the dry season, which can occur during any time of the year. If 3.85 mgd is withdrawn during this four-month period, the withdrawal rate for the remaining 8 months cannot exceed 2.21 mgd. (Other Condition 8) The CUP recommended by the TSR would limit the City’s potable water allocation from the Area IV Wellfield to a maximum rate of 4.41 mgd during any single month. (Other Condition 7) The CUP recommended by the TSR would limit the City’s potable water allocation from the Area IV Wellfield to a maximum rate of 6.5 mgd during any single day during a severe drought, when the existing sources (meaning Areas II and III) cannot be used without inducing water quality degradation or exceeding permitted quantities. (Other Condition 9) The CUP recommended by the TSR would allow the City to withdraw water from the SAS extraction wells at an annual average rate of up to 0.178 mgd in 2009 and 2010 for wetland hydration and surficial aquifer recharge. (Other Condition 6) The CUP recommended by the TSR would limit the withdrawal of water from the Area II, III and IV Wellfields to a combined annual average rate of 5.79 mgd in 2009 and a combined annual average rate of 6.01 mgd in 2010. The CUP recommended by the TSR would limit the withdrawal of water from the Area II, III and IV Wellfields to a combined maximum daily rate of 8.88 mgd in 2009 and 9.0 mgd in 2010. (Other Conditions 5, 9) The CUP recommended by the TSR would reduce Titusville's combined annual average and maximum daily allocations from the Area II, III and IV Wellfields in 2009 and 2010 by an amount equivalent to the quantity of water purchased from the City of Cocoa during each year. (Other Conditions 5, 9) Other Condition 10 in the recommended by the TSR notifies the City that nonuse of the water supply allocated by the CUP for two years or more is grounds for revocation by the District's Governing Board, permanently and in whole, unless the City can prove that its nonuse was due to extreme hardship caused by factors beyond the City's control. Permit Duration The CUP recommended by the TSR would not allow the City to withdraw water from the Area IV Wellfield earlier than January 1, 2009; as indicated, it would expire on December 31, 2010. (Other Conditions 2, 4). Saline Water Intrusion The CUP recommended by the TSR contains a permit condition requiring the City to implement the proposed saline water monitoring plan by sampling and analyzing Saline Water Monitor Wells SWMW 1-6 and UFAS production wells 401, 403, 405, 407, 409, 411, 413 and 415 quarterly for water levels, chloride and total dissolved solids. (Other Condition 11) The CUP recommended by the TSR contains a permit condition authorizing the District to modify the allocation granted to the City in whole or in part or to otherwise curtail or abate the impact in the event of saline water intrusion. (Other Condition 14) The CUP recommended by the TSR contains a permit condition requiring the City to cease withdrawal from any UFAS production well, if any quarterly water sample from that well shows a chloride concentration exceeding 250 mg/l. That same condition would limit the operation of any UFAS production well with a quarterly sample exceeding 250 mg/l to six hours per day with a minimum 24 hours recovery between pumping cycles if subsequent samples contain chloride concentrations between 200 mg/l and 249 mg/l. (Other Condition 25) Environmental Impacts and Avoidance and Minimization The CUP recommended by the TSR contains a permit condition requiring the City to implement the proposed environmental monitoring plan for hydrologic and photo- monitoring at 16 wetland sites within one year of permit issuance and to establish a baseline prior to the initiation of groundwater withdrawals. That same condition requires the City to collect water level data at each wetland site either on a daily or weekly basis and report to the District every six months in District-approved, computer-accessible format. (Other Condition 12) The CUP recommended by the TSR contains a permit condition authorizing the District to revoke the permit in whole or in part or to curtail or abate impacts should unanticipated adverse impacts occur to wetlands, lakes and spring flow. (Other Condition 23) The CUP recommended by the TSR contains a permit condition authorizing the District to require the City to implement the proposed avoidance and minimization plan should unanticipated impacts occur to Wetland A4-2 (a shallow marsh near the middle of the wellfield) within 90 days of notice by the District. That same permit condition authorizes the District to require the City to submit a wetland rehydration plan for any other adversely affected wetland within 30 days of notice by the District and to implement the plan without 90 days of approval by the District. The District would require the City to implement avoidance measures before the wetlands are actually allowed to suffer adverse impacts. (Other Condition 24) Impacts to Other Existing Legal Users of Water The CUP recommended by the TSR contains a permit condition authorizing the District to require mitigation of any unanticipated interference to existing legal users of water due to withdrawals from the Area IV Wellfield. Mitigation may include installation of a new pump or motor, installation of additional drop pipe, new electrical wiring, connection with an existing water supply system, or other appropriate measures. (Other Condition 15) Water Conservation Measures and Reuse The City is implementing extensive water conservation measures. The City’s water conservation plan includes public education measures (e.g., televised public service announcements, helping to create water conservation videos and distributing them to the public, commissioning an award winning native plant mural, providing exhibits and speakers for public events), toilet and showerhead retrofits, and a water conservation based rate structure. A water conservation rate structure provides the potable water customer with an economic incentive to use less water. The most common conservation rate structure is a tiered-rate whereby the cost per gallon of water increases as the customer uses more water. While the District reviews the rate structure to evaluate whether it will achieve conservation, it does not mandate the cost per gallon of water. An audit of the City’s potable water distribution system was conducted and recent water use records were evaluated to determine if all necessary water conservation measures were in place. The audit indicated that the potable water system has small unaccounted-for water losses, approximately 6.5 percent, and relatively low residential per capita water use. The City has implemented a water conservation plan that implements rule requirements; as a result, the City has provided reasonable assurance that it is implementing all available water conservation measures that are economically, environmentally, or technologically feasible. The City cannot use reclaimed water to meet its potable water demands associated with direct human consumption and food preparation. However, reclaimed water can be used to replace that part of the City’s allocation that is associated with irrigation-type uses. The City has operated a reclaimed water reuse system since 1996. It is projected that 67 percent of the available wastewater flows will be utilized by 2010 for irrigation, with the remainder going to a wetland system during wet weather periods when irrigation demands are low. The City is using reclaimed water to the extent it is economically, environmentally and technologically feasible. In the case of public supply, the District looks to the amount of water requested for each person in a projected population in determining whether the water will be used efficiently. The metric that the District normally considers when conducting this part of the evaluation is the per capita usage. Population Projections and Per Capita Water Use As indicated, the proposed CUP would expire on December 31, 2010. Although the City and District would anticipate an application for renewal to be filed, demand for water projected beyond December 31, 2010, is not relevant to the need for the proposed CUP. In the case of public supply, projected demand for water usually is calculated by multiplying the projected population times per capita water use. Gross per capita (“GPC”) use in gallons per day (gpd) is the type of metric normally used to project demand for public supply of water. It is based on residential use and all other water uses supplied by the utility, including commercial, industrial, hotel/motel, and other type uses. That includes supply necessary to meet peak demands and emergencies. DEP requires that every public water supply system have an adequate water supply to meet peak demands for fire protection and health and safety reasons. If peak demands are not met, a major fire or other similar catastrophe could depressurize a public water system and possibly cause water quality problems. Projections of need for water in the future must take into account peak demands and emergency needs. Water used for those purposes is included in the historical average daily flows (ADF) from which historical GPC is derived. Unless there is good information to the contrary, in projecting GPC one assumes that those uses will increase roughly in proportion to the residential use. City's Projection Contending that the University of Florida Bureau of Economic and Business Research (BEBR) does not estimate or project population for municipalities, and that BEBR projections are based on historical trends that would under-project population in the City, the City used a different source and method to project population in the City's water service area on December 31, 2010. For its method, the City had Courtney Harris, its Planning Director, project the number of dwelling units that would be developed and occupied in 2011, calculating the additional people associated with each unit (based on the 2000 Census, which identified 2.32 as the average number of persons per dwelling unit in the City), and adding the resulting number to the City’s existing service area population as of 2005. The City's method yielded various results depending on when proposed developments in the City were reviewed. Ultimately, the City projected a population of 60,990 at the end of 2010. The City's method depends on the ability of its Planning Director to accurately predict the timing of new residential construction and sales, which is not easy to do (as indicated by the different results obtained by the City over time), since there are many factors affecting residential development and the real estate market. The ultimate predictions of the City's Planning Director assume that residential development will continue at an extraordinarily high pace although there already was evidence of downturn. The City's method also assumed that all new units will be sold (which, again, is contingent on market conditions) and fully occupied (although a 90 percent occupancy rate would be a more realistic.) The method also does not account for decreases in population in a number of areas in the Titusville service area (while overall population increased, mostly as a result of growth that has been occurring in a single census tract.) The City's witnesses then calculated a per capita water use rate by averaging the actual rates for the 11 years from 1995 through 2005, which resulted in projected per capita water use rate of 100.35, and a projected demand of 6.12 mgd at the end of 2010. The justification for averaging over 11 years, instead of the last five years, was that the last five years have been unusually wet, which would depress demand to some extent. However, using 11 years also increased the average water use by taking into account the higher use rates common before conservations measures, including conservation rates, went into effect (in particular, 123.75 gpd for 1995, 122.36 gpd for 1996, and 109.94 gpd for 1998.) Since 1998, and implementation of the conservation rates and other measures, water use rates have been significantly lower. While the average over the last 11 years was 100.35 gpd, the average over the last five years (from 2001- 2005) was just 92.15 gpd. Averaged since 1998, the City's water use rate has been 93.34 gpd. While wetter-than-normal conditions would be expected to depress water use to some extent due primarily to decreased lawn irrigation, many of the City's water customers have private irrigation wells for this purpose. Besides, Mr. Peterson, the City's Water Resources Manager, testified that not many of the City's water customers use potable water for lawn irrigation due to the new conservation rates. Petitioners' Projection Miami Corporation's population expert, Dr. Stanley Smith, is the Director of BEBR. Dr. Smith projected the population for the City's service area by first developing an estimate of the population of the water service area in 1990 and 2000 using block and block group data, and then using those estimates to create estimates from 2001-2005. Dr. Smith then projected population in the City's water service area using a methodology similar to what BEBR uses for county projections. Dr. Smith's methodology used three extrapolation techniques. He did not use a fourth technique, often used at BEBR, called shift-share, because he believed that, given Titusville's pattern of growth, using shift-share might produce projections that were too low. In developing his final projections, Dr. Smith also excluded the data from 1990 to 2000 because growth during that period was so slow that he felt that its inclusion might result in projections that were too low. Dr. Smith's approach varied slightly from the typical BEBR methodology in order to account for the fact that the City's growth has been faster since 2000. Dr. Smith applied an adjustment factor based on an assumption also used by the City's expert that 97.3 percent of the projected population within the City's water service area in 2010 would be served by the City. Using his method, Dr. Smith projected the population of the Titusville water service area to be 53,209 on December 31, 2010. Based on recent population estimates, Dr. Smith believes that, if anything, his projections are too high. It was Dr. Smith's opinion from the data that the annual increases for Titusville and the Titusville water service area peaked in 2003 and that they had been declining since that time. That was especially true of 2006, when the increase was the smallest that it had been for many years. Petitioners' expert, Mr. Drake, calculated a per capita water use rate by averaging the actual rates for the most recent five years (2002-2006), which resulted in a per capita water use rate of 89.08 gpd, and a projected demand of 4.74 mgd at the end of 2010. He also calculated a per capita water use rate for 2006, which came to 88.65 gpd, which would give a slightly lower projected demand of 4.72 mgd. Ultimate Finding of Projected Water Demand Based on all the evidence, it is found that Dr. Smith's projection of the population that will use City water on December 31, 2010, is more reasonable than the City's projections. The City and District contend that, regardless of the calculated per capita water use rate, it is appropriate to base the City's allocation on a rate of 100.35 gpd because 90 to 100 gpd is very conservative per capita water use rate for a public water supply utility. However, the allocation should be based on the best estimate of actual demand, not a general rate commonly assumed for water utilities, even if conservative. The City and District also contend that it is appropriate to base the City's allocation on a higher use rate because the climatic conditions experienced in the City over what they considered to be the most recent five years (2001- 2005) have been average-to-wet. More rainfall generally means less water use, and vice-versa, but the greater weight of the evidence proved that the City's demand for water has not varied much due to climatic conditions in recent years (after implementation of conservation measures, including conservation rates.) (City Exhibit 19, which purported to demonstrate the contrary, was proven to be inaccurate in that it showed significantly more water use during certain drier years than actually occurred.) However, in 2000--which was after the implementation of conservation rates and also the City's driest year on record (in approximately 75 years)--the water use rate was approximately 97.5 gallons per person per day. An average of the last eight years (1999-2006), which would include all years clearly responsive to the conservation rates as well as the driest year on record, would result in a per capita water use rate of approximately 92.8 gpd, and a projected demand of approximately 4.94 mgd by December 31, 2010. The District argues in its PRO that, because a CUP water allocation is a legal maximum, it would be inappropriate to base the City's water allocation on demand during a wet or even an average year (which, it says, would set the permittee up to violate its permit requirements 50 percent of the time). If, instead, the City's water allocation were based on demand during 2000, the driest year on record, projected demand would be approximately 5.2 mgd on December 31, 2010. Those calculated water allocations--i.e., either the 4.94 mgd or the 5.2 mgd--would then be compared to the probable safe and reliable yield of 4.5 mgd from Areas II and III to determine the deficit on an annual average basis. Allowing a reasonable margin of error for the uncertainties of the predictions involved, a reasonable maximum annual average allocation for the proposed Area IV Wellfield would be 0.75 mgd. Mr. Jenkins suggested in rebuttal that, if the need for water is less than that set out in the proposed CUP in the TSR at issue, a CUP should nonetheless be issued but with lower water allocations. While the evidence supports a reduction of the annual average limit from 2.75 mgd to 0.75 mgd, there was insufficient evidence to show how the other water allocation limits in the proposed CUP should be changed. For the past 12 years, the City of Titusville has been able to purchase water under a contract with the City of Cocoa to meet all of its demands, including any peak or emergency water demands. Under the take-or-pay provision in the contract currently in effect, the City must pay for 0.5 mgd and presumably would take and use at least that amount so long as the contract remains in effect. This would reduce the City's projected water supply deficit through the end of 2010, and the City could rely on the Cocoa contract to cover any additional demand through the end of 2010 without Area IV. However, under the contract, the City can give notice on or before April 1 of the year in which it intends to terminate the contract effective October 1 of the same year. If a CUP for Area IV is issued, the City could terminate the current contract effective as early as October 1, 2008. It also is possible that the contract could be negotiated so that its termination would coincide with the time when the Area IV Wellfield becomes operational if not near October 1 of the year. As indicated, even if the contract remains in place, to the extent that the City receives water from the City of Cocoa for potable use during either 2009 or 2010, the allocations under the proposed TSR will be reduced an amount equivalent to the quantity provided to the City by Cocoa in that year. Finally, as indicated, the existing CUP for Areas II and III is set to expire in February 2008. Although it is anticipated that the City will apply to renew the existing CUP for Areas II and III, and that the District will approve a renewal at some level, it is not clear how much production will be approved for Areas II and III for the years 2009 and 2010. Meanwhile, the CUP proposed for Area IV provides that the combined annual groundwater withdrawals for public supply for the Areas II, III, and IV may not exceed 5.79 mgd for 2009 and 6.01 mgd in 2010. Based on the findings in this case, those figures should be reduced to no more than 5.2 mgd, and it must be anticipated that a similar condition would be placed on any renewal of the existing CUP for Areas II and III as well. Site Investigation At the time the City decided to apply for a CUP for Area IV, it was known that the UFAS in much of Brevard County was not suitable as a source of potable water supply, but there was believed to be a tongue of the UFAS in the northwest corner of the County and extending towards the southeast, and narrowing in that direction, that might be suitable for that purpose, particularly in the upper part of the aquifer. Because there was insufficient information to adequately evaluate the whether proposed Area IV, which was located along the Florida East Coast Railway (FEC) Right-of-Way (ROW), could be used for that purpose, the City’s consultant, Barnes, Ferland and Associates (BFA), designed a drilling and testing program to collect site-specific information in order to characterize the groundwater quality, identify the thickness of the freshwater zone in the UFAS, and determine hydraulic parameters for the groundwater system. In addition, DRMP conducted an environmental assessment of the Area IV Wellfield and surrounding property. The drilling and testing program designed by BFA for the Area IV Wellfield was similar to other hydrogeologic investigations conducted in the region with respect to wellfields operated by the City of Edgewater, the City of New Smyrna Beach, the City of Ormond Beach, the Orlando Utilities Commission and Orange County. The drilling and testing program for the Area IV Wellfield included Time-Domain Electromagnetic Mapping ("TDEM") performed by SDII Global, a consultant retained by the District. TDEM is not typically used for the hydrogeologic investigation of a new wellfield. The TDEM technique involves estimating the depth to the 250 mg/l and 5,000 mg/l chloride concentration in the groundwater system using electrical resistivity probes. The technique was applied at four locations along the FEC Right-of- Way. In addition to the TDEM study, BFA installed three test production wells along the FEC ROW, collected lithologic samples with depth, performed borehole aquifer performance and step drawdown tests at two test sites and recorded water quality with depth through grab and packer samples. The northernmost test production well was Test Site 1, which corresponds to Area IV production well 401. The middle test production well was Test Site 3, which corresponds to either Area IV Well 412 or Area IV Well 413. The southernmost test production well was Test Site 2, which is located approximately 1.5 miles south of the southernmost Area IV production well. Test Sites 1 and 2 were constructed first and Test Site 3 was drilled later because of unfavorable water quality conditions encountered at Test Site 2. Test Site 1 is located on the FEC ROW approximately 430 feet southeast of the Volusia-Brevard County line. At Test Site 1, BFA installed a test-production well (UF-1D), a UFAS monitor well (UF-1S), and a SAS monitor well (SA-1) in 2001. In 2005 BFA installed two additional SAS monitor wells (MW-1 and RW-1) near Test Site 1. The test production well was drilled to a depth of 500 feet below land surface and then back-plugged to a depth of 250 feet below land surface and cased to a depth of 105-110 feet below land surface. Test Site 2 is located on the FEC ROW approximately 2.8 miles southeast of the Volusia-Brevard County line. At Test Site 2, BFA installed a single UFAS Monitor Well (UF-2S). The monitor well was drilled to a total depth of 210-220 feet below land surface. Test Site 3 is located on the FEC ROW approximately 1.4 miles southeast of the Brevard-Volusia County line. At Test Site 3, BFA installed a test production well (UF-3D), a UFAS monitor well (UF-3S), and a SAS monitor well (SA-3). The test production well was drilled to a depth of 500 feet below land surface and then back-plugged to a depth of 210 below land surface.. Since Test Site 3 is either Area IV Well 412 or 413, and assuming production well 415 will be located 1,200 feet southeast of Test Site 3, this means that Test Site 2 is located at least one mile southeast of the southernmost Area IV production well. Test Sites 4 and 6 are located approximately three miles southeast of Brevard-Volusia County line. SAS test production wells were constructed at both sites to a total depth of about 20-30 feet below land surface. The site-specific hydrogeologic data collected by BFA as part of the drilling and testing program verified the groundwater basin and flow direction shown in Figure 15 of City Exhibit 523. DRMP’s environmental assessment of the Area IV Wellfield spanned the period from 2002 through 2006. In Spring 2002, DRMP evaluated areas within the predicted 0.2 foot drawdown contour by assessing wetland vegetation, photographing wetlands, noting wetland hydrologic conditions, investigating soil condition and wildlife utilization and evaluating surrounding land uses and natural communities. In Fall 2002, DRMP evaluated potential monitoring sites both on and off Miami Corporation's property by assessing wetland vegetation composition and hydrologic conditions, investigating soil conditions and wildlife utilization, evaluating surrounding land use and natural communities and locating suitable control sites. In Fall 2003, DRMP evaluated potential wetland monitoring sites near the southernmost Area IV production wells by assessing wetland vegetation composition and hydrologic conditions, investigating soil conditions and evaluating surrounding land uses and natural communities. In Spring 2005, DRMP assessed wetlands surrounding the Area IV Wellfield by evaluating wetland vegetation composition and hydrologic conditions, photographing wetlands, investigating soil conditions, evaluating surrounding land use and natural communities and collecting GPS points. In Fall 2005, DRMP investigated the Clark property by evaluating wetland vegetation and hydrologic conditions, photographing wetlands, investigating soil conditions and wildlife utilization and evaluating surrounding land uses and natural communities. In Spring 2006, DRMP developed a revised environmental monitoring plan and avoidance and minimization plan based on the new SDI MODFLOW Model by locating the final wetlands monitoring sites, developing the hydrologic and vegetative monitoring protocol, establishing the scope of the baseline study, reviewing the preliminary pipeline routing, construction and discharge inlet structures and preparing and submitting plan documents to the District. DRMP evaluated the occurrence of listed animal and plant species in the vicinity of the Area IV Wellfield as part of its environmental assessment. DRMP reviewed the Natural Areas Inventory for the Area IV Wellfield site, which identifies occurrences of listed species within a designated area. Additionally, DRMP made note of animal and plant species during the site visits in 2002, 2003, 2005, and 2006. DRMP evaluated the Farmton Mitigation Bank as part of its environmental assessment. DRMP reviewed the permit files for the Farmton Mitigation Banks, including the annual environmental monitoring reports prepared by Miami’s consultants. In 2005, DRMP conducted a field assessment of the Clark property including a thorough investigation of the fish pond, which Petitioners claim was adversely impacted during one or more of the APTs conducted by the City at the Area IV Wellfield. It was not necessary for the City’s environmental consultants to visit each and every wetland in the vicinity of the proposed Area IV Wellfield. Typically, only representative wetland sites are visited during the environmental assessment process. The scope of the City's hydrologic and environmental investigation of the Area IV Wellfield was adequate and consistent with industry standards and the District protocol for testing aquifers and characterizing aquifer performance and groundwater quality at the site. Nonetheless, Petitioners contend that there were serious deficiencies in the investigation's implementation and that additional investigation should have been performed. Hydrostratigraphy The SAS at the Area IV Wellfield is 40-to-50 feet deep and is composed primarily of unconsolidated sand, shell and silt. The intermediate confining unit (ICU) at the Area IV Wellfield consists of the Hawthorne Group and ranges in thickness from 40 to 60 feet. The top of the ICU is located 40- 50 feet below land surface and the bottom of the ICU is located 100 feet below land surface. This unit is composed of varying amounts of sand, shell, silt, indurated sandstone, clay, and some limestone. It tends to restrict the movement of water from the SAS to the UFAS. The UFAS at the Area IV Wellfield is a fairly homogenous limestone unit, which starts approximately 100 feet below land surface and extends to about 450 feet below land surface or 425 feet below mean sea level. It consists of the Ocala Group and grades into the upper portion of the Avon Park Formation. The middle confining unit (MCU) at the Area IV Wellfield starts at approximately 450 feet below land surface or 425 feet below mean sea level and ends approximately 1,000 feet below land surface. It comprises a denser, fine-grained dolomitic limestone within the Avon Park Formation. The MCU restricts the movement of water between the UFAS and LFAS. The location of the MCU at the Area IV Wellfield was determined by examining cuttings and video logs collected during drilling performed at Test Sites 1 and 3 and by measuring various properties of the aquifer with down-hole geophysical techniques. The MCU can be distinguished from the UFAS by the presence of both dolomite and limestone. The lithologic log for Test Site 1 indicates the presence of gray/tan limestone between 450 and 460 feet below land surface and light/gray limestone and dolomitic limestone between 460 and 470 feet below land surface. The lithologic log for Test Site 3 indicates the presence of tan dolomitic limestone between 450 and 460 feet below land surface and tan limestone and dolomitic limestone between 460 and 470 feet below land surface. After examining the video log for Test Site 1, Petitioners’ expert, Dr. Thomas Missimer, noted a “lithologic change” at 477 feet below land surface. Other characteristics of the MCU are a lower resistivity and a sharp decrease in flow. The data collected at Test Site 1 shows a reduction in resistivity at approximately 470 feet below land surface. The flow meter log for Test Site 1 exhibits a decrease in flow at approximately 450 feet below land surface. Petitioners’ experts, Thomas Missimer, Alge Merry, and Bruce Lafrenz contend that the top of the MCU at the Area IV Wellfield is located deeper than 450 feet below land surface or 425 feet below mean sea level. This contention is based on regional reports, the geophysical logs reported by BFA, and one of the packer tests conducted at the bottom of the test wells that showed a pumping rate of 85 gpm. The greater weight of evidence indicates the top of the MCU at the Area IV Wellfield starts at the elevation identified by BFA. The regional reports are not based on data collected from the immediate vicinity of the Area IV Wellfield. Additionally, the BFA's professional geologists who determined the top of the MCU included Joel Kimrey, who was the former head of the local USGS office, and had more experience with the hydrogeology of the MCU in Brevard and Volusia than any of the Petitioners’ geologic experts. Also, the BFA geologists had access to the drill cuttings, which were unavailable to the Petitioners’ experts when they made their determination. Finally, the pumping rate recorded during the packer test could be explained by an area of higher permeability within the MCU. More likely, the packer may have been partially open to the bottom of the UFAS. The Lower Floridan Aquifer System (LFAS) starts at about 1,000 feet below land surface and ends approximately 2,300 feet below land surface. Head Difference Data Head refers to the pressure within an aquifer. In an unconfined aquifer, it is the water table. In a confined or semi-confined aquifer, it is the level to which water would rise in a well penetrating into the aquifer. Head difference refers to the numerical difference between two water levels either in different aquifer at the same location or different locations in the same aquifer. In the context of the Area IV Wellfield, static head difference is the difference between the elevation of the water table in the SAS and the elevation of the potentiometric surface of the UFAS under non-pumping conditions at the same location. The static head difference reflects the degree of confinement in the ICU. If the static head difference between the SAS and UFAS is a large number, this indicates a high degree of confinement between the two systems. BFA took static head measurements at SAS and UFAS monitor wells located at Test Sites 1, 2 and 3 in January 2004, April 2004, and July 2006 and calculated the head difference based on those measurements. District expert, Richard Burklew, was present when the measurements were taken in April 2004 and July 2006 and verified the readings made by the City’s consultants. During all three sampling events a downward head gradient was noted at each site, which means the water table had a higher elevation than the potentiometric surface of the UFAS. In January 2004, the measured head difference at Test Sites 1, 2 and 3 were 6.2 feet, 5.5 feet and 5.9 feet, respectively. In April 2004, the measured head difference at Test Sites 1 and 3 were 8.1 feet and 8.1 feet, respectively. Finally, in July 2006, the measured head difference at Test Sites 1, 2 and 3 were 8.6 feet, 6.6 feet and 9.3 feet, respectively. The average of those observed head differences was 7.46 feet. At the time the head difference measurements were taken in July 2006, the region had experienced a rainfall deficit of 17 inches over the prior 12 months. Petitioners contend that the rainfall deficit may have skewed that head difference observation. However, according to the District’s expert, Richard Burklew, this would not necessarily have affected the head difference measurements because the hydrologic system would seek equilibrium, and the head difference would be the same. BFA collected static head difference measurements from Test Sites 1, 2 and 3 during both wet and dry seasons. The measurements do not show significant differences between seasons. Head difference data collected from hundreds of other Florida locations also do not show significant differences between seasons. This suggests that static head difference remains fairly constant at the Area IV Wellfield year round. Water level measurements taken by the City’s consultants from the wells on Clark’s property and reported in City Exhibit 52 do not determine static head difference between the SAS and UFAS because the exact construction of the wells was unknown, the completion depth of certain wells was unknown, the operational history of the wells was unknown, and the putative SAS well was located several hundred feet away from the UFAS well. For example, the depth of one of the wells is reported as 57 feet, which could easily be located in the ICU. If that is the case, then the head difference measured by comparing to the water level in this well would only be the head differential between the ICU and the UFAS. Finally, the Clark property is located in a more elevated region than Test Sites 1, 2, and 3, which means the water table will be lower and the head difference will be less than at the Area IV Wellfield. Water level measurements reported in the driller’s completion log for Wells 4175, 4176, 4177, and 5230 on Miami Corporation’s property do not determine static head difference between the SAS and UFAS because critical information concerning the construction of these wells is unknown. Additionally, the wells are much shallower than test production wells at Test Sites 1, 2 and 3. The water level measurements reported in the driller’s completion log for Wells 4175, 4176, 4177, and 5230 are not necessarily inconsistent with head difference measurements collected by BFA at Test Sites 1, 2 and 3. The head differences at these four well sites could be 6, 4, 7, and 6 feet, respectively, depending how the water measurements were made. Also, the measurements made by a driller could not be expected to be as accurate as measurements made by trained hydrologists. Further, if the soils in the vicinity of Well 4177 indicated a depth to water table of 5 feet below land surface, that would not necessarily be inconsistent with the head difference measurements collected by BFA at Test Sites 1, 2 and 3. Depth to Water Table The depth to water table is defined as the difference between the land surface elevation and the head value in the SAS. The water table in the Area IV Wellfield area is consistently close to land surface and often above land surface. The construction of numerous above-grade forest roads and roadside ditches on the property surrounding the Area IV Wellfield has had the effect of impounding surface water and raising the water table near land surface. The Area IV Wellfield and vicinity have a variety of soil types. The predominant wetland soil type is Samsula Muck, which is classified as a very poorly drained soil with a water table either at or above land surface. The predominant upland soil type is Myakka Fine Sand, which is characterized by a water table within a foot of land surface during four months of the year and within 40 inches of land surface during remainder of the year. The average depth to water table at the Area IV Wellfield is approximately 1 foot based on soil types. SAS levels at the three Farmton Mitigation Banks were measured at piezometers installed by Miami Corporation’s consultants from 2001 through 2005. This data confirms the water table at the Area IV Wellfield is consistently close to land surface and frequently above land surface. It indicates the depth to water table is typically less than 3 feet and in many cases within a foot or two. Also, it does not matter whether any of the piezometers were located near wetlands because they show seasonal variation in water levels, where the water table changes from slightly above land surface to below land surface over the course of a year. A water table depth of 6-14 feet below land surface is not realistic at the Area IV Wellfield based on soil conditions and vegetation communities. Such a depth to water would be indicative of a landscape composed primarily of xeric scrub communities with few, if any wetlands. These types of communities do not exist near the Area IV Wellfield. Aquifer Performance Tests The flow of water through an aquifer is determined by three primary hydraulic coefficients or parameters: transmissivity; storage; and leakance. An aquifer performance test (APT) is a pumping test where water is removed from the well at a set rate for a set period of time and drawdown is measured in the well and in neighboring monitor wells to calculate the hydraulic properties of the hydrologic formation. The main hydraulic properties determined through an APT are transmissivity, leakance, and storativity. These properties are used to characterize the water production capabilities of the hydrologic formations. These properties are also used in groundwater modeling to project impacts for longer periods of time and larger distances. Aquifer parameters can be determined from an aquifer performance test using analytical "curve-matching" techniques or a groundwater flow model such as MODFLOW. Curve-matching techniques involve the creation of a curve through measurement of drawdown and the matching of that curve to standard curves derived using analytical equations. Hydraulic conductivity or “K” is the term used to describe the ability of a hydrogeologic unit to conduct fluid flow. It is usually expressed in terms of horizontal hydraulic conductivity or “Kx” and “Ky” and vertical hydraulic conductivity or “Kz.” Transmissivity is the term used to describe the rate of movement of water for a given thickness of a hydrogeologic unit. It is the hydraulic conductivity of an aquifer times its thickness. Storativity is the term used to describe the amount of water that is released from any aquifer for a given unit change in head, or the compressability of the aquifer system. This value can normally be determined during a 4-5 day aquifer performance test. Specific yield is the term used to describe the long- term capacity of an aquifer to store water. This value cannot normally be determined during a 4-5 day aquifer performance test. Leakance is the term used to describe the vertical movement of water from above or below a given unit in response to changes in head or pumpage. APTs are standard practice for evaluating the suitability of a new area for development as a wellfield. Three APTs were conducted at Test Sites 1 and 3. No aquifer performance tests were conducted at Test Site 2. Petitioners question whether the APTs for the Area IV Wellfield were conducted by BFA in accordance with the applicable standard of care in the hydrogeologic profession. The District’s expert, Richard Burklew, believes the three APTs conducted at Test Sites 1 and 3 were adequate for purposes of determining appropriate aquifer parameters. Two APTs were conducted by BFA at Test Site 1. The first test was conducted on January 30-31, 2001, when Well UF-1D was pumped at about 700 gpm or approximately 1 mgd for 44-48 hours, and Wells UF-1S and SA-1 were used as monitor wells. The second test was conducted on April 8-12, 2003, when Well UF-1D was pumped at about 700 gpm or approximately 1 mgd for 96 hours, and Wells UF-1S and SA-1 were used as monitor wells. Using several analytical curve-matching techniques, BFA calculated a transmissivity of 7,300 ft2/day and a storativity of about 0.00036 on the basis of the 2001 APT at Test Site 1. They were unable to calculate a leakance value because the drawdown data did not reasonably fit the curve- matching techniques. For that reason, BFA performed another APT at Test Site 1 in 2003. Using several analytical curve-matching techniques, BFA calculated a transmissivity of 7,300 ft2/day, a storativity of 0.00045, and a leakance of 0.00029 day-1 on the basis of the 2003 APT at Test Site 1. One APT was conducted by BFA at Test Site 3 on April 10-13, 2001. Well UF-3D was pumped at about 700 gpm or approximately 1 mgd for 70 hours, and Wells UF-3S and SA-3 were used as monitor wells. Using several analytical curve-matching techniques, BFA calculated a transmissivity of 7,450 ft2/day, a storativity of 0.0002, and a leakance of 0.00026 on the basis of the 2001 APT at Test Site 3. However, because of problems with the test, leakance was not considered a good match for the analytical techniques. Leakance values determined by BFA from the APTs conducted at Test Sites 1 and 3 were based on the application of analytical curve-matching techniques. The leakance values determined through the conventional type curve-matching techniques employed by BFA are typically higher than the actual leakance values. They are also inherently limited because they assume the calculated leakance is due entirely to the ICU rather than a combination of the ICU and MCU as is the case at the Area IV Wellfield. The analytical techniques employed by BFA were unable to calculate separate leakance values for the ICU and the MCU. The best way to determine leakance values for each of these confining units was to use a MODFLOW model and observed head difference data. This was done by the City’s consultant, SDI, and is described in greater detail, infra. In January 2004, several APTs were conducted using two SAS wells referred to as Test Sites 4 and 6. These test sites are located more than 3 miles from the Clark property. Constant rate and variable rate APTs were conducted at both sites. During the constant rate tests, 230 gpm or about 0.33 mgd was pumped from the SAS well. Using several analytical curve-matching techniques, BFA calculated a transmissivity of 2,500 ft2/day for the surficial aquifer at those locations. Water Quality Data Consistent with the general understanding of the freshwater groundwater tongue extending from Volusia into Brevard County, the TDEM performed by SDII Global indicated that the depths to the 250 mg/l and 5,000 mg/l chloride concentrations decrease as one proceeds south along the FEC ROW. For example, the depths to the 250 mg/l and 5,000 mg/l chloride concentrations were 442 feet and 542 feet, respectively, at the northernmost test site, which is somewhat north of the City’s Test Site 1. The depth to the 250 mg/l and 5,000 mg/l chloride concentrations were 406 feet and 506 feet, respectively, at the southernmost test site, which is somewhat south of the City’s Test Site 2. Sixteen water quality grab samples were collected every 20-30 feet as the test production well at Test Site 1 was drilled, beginning at 120 feet below land surface and ending at 500 feet below land surface. This type of sampling is referred to as drill-stem testing. The chloride concentrations in the samples collected from 120 feet and 480 feet below land surface were 59 mg/l and 879 mg/l, respectively. The chloride concentrations in these samples did not exceed 250 mg/l until a depth of 460 feet below land surface was reached. Six water quality grab samples (drill-stem tests) were collected every 20-30 feet as the test production well at Test Site 2 was drilled, beginning 120 feet below land surface and ending 210 feet below land surface. The chloride concentrations in the samples collected from 120 feet and 210 feet below land surface were 124 mg/l and 845 mg/l, respectively. The chloride concentrations in these samples did not exceed 250 mg/l until a depth of 180 feet below land surface. Fourteen water quality grab samples (drill-stem tests), were collected every 20-30 feet as the test production well at Test Site 3 was drilled, beginning at 120 feet below land surface and ending at 500 feet below land surface. The chloride concentrations in the samples collected from 120 feet and 500 feet below land surface were 45 mg/l and 90 mg/l, respectively. The chloride concentrations in these samples never exceeded 90 mg/l. A packer test is a procedure used to isolate a particular well interval for testing. It is performed using an inflatable packer on the drill stem, which is placed at the interval to be blocked. The packer is inflated with water or air to isolate the interval to be sampled. A packer test can be used to collect water samples for analysis. Several water quality grab samples were collected in packer tests at specific depth intervals at Test Site 1. At the interval of 331-355 feet below land surface one sample was taken with a chloride concentration of 672 mg/l. At the interval of 331-400 feet below land surface, one sample was taken with a chloride concentration of 882 mg/l. Finally, at the interval of 442-500 feet below land surface two samples were taken with chloride concentrations of 2,366 mg/l and 2,2712 mg/l. Several water quality grab samples were collected in packer tests at specific depth intervals at Test Site 3At the interval of 270-295 feet below land surface, two samples were taken with chloride concentrations of 74 mg/l and 450 mg/l. At the interval of 340-400 feet below land surface, two samples were taken with chloride concentrations of 64 mg/l and 134 mg/l. Finally, at the interval of 445-500 feet below land surface, two samples were taken with chloride concentrations of 1,458 mg/l and 2,010 mg/l. No packer test samples were collected at Test Site 2, where it was clear that water quality was too poor to be used as a fresh groundwater source. The packer test samples collected at Test Sites 1 and 3 were collected using a higher pumping rate than typically recommended by the DEP and the United States Environmental Protection Agency (EPA). Consequently, the chloride concentrations in these samples are probably higher than the chloride concentrations found in the undisturbed groundwater at those depths. Since the packer sits on top of the borehole and restricts flow from above, it generally is reasonable to assume that a packer test draws more water from below than from above the packer. However, if transmissivity is significantly greater just above the packer, it is possible that more water could enter the packer from above. Seven water quality grab samples were collected every 12 hours during the 2001 APT at Test Site 1. The chloride concentrations in the first and last grab sample were 59 mg/l and 58 mg/l, respectively. Seven water quality grab samples were collected every 12 hours during the 2001 APT at Test Site 3. The chloride concentrations in the first and last grab samples were 19 mg/l and 52 mg/l, respectively. Nine water quality grab samples were collected every 12 hours during the 2003 aquifer performance test at Test Site The field-measured chloride concentrations in the first and last grab samples were 56 mg/l and 55 mg/l, respectively. The laboratory measured chloride concentrations in the first and last grab samples were 66 mg/l and 74 mg/l, respectively. The average chloride concentration for the water samples collected during the three APTs at Test Sites 1 and 2 was about 50 mg/l. Water is composed of positively charged analytes (cations) and negatively charged analytes (anions). When cations predominate over anions, the water is said to have a positive charge balance; when anions predominate over cations, the water is said to have a negative charge balance. Theoretically, a sample of water taken from the groundwater system should have a charge balance of zero. However, in real life this does not occur because every sample contains some small trace elements that affect its charge balance. Therefore, in the field of hydrogeology, a positive or negative charge balance of 10 percent or less is accepted as a reasonable charge balance error, and this standard has been incorporated in the permit conditions recommended by the District for the City’s permit. With one exception, all the water quality samples collected by BFA from Test Sites 1-3 had an acceptable charge balance. The one exception was a sample collected from the packer interval of 270-295 feet below land surface at Test Site 3 with a chloride concentration of 74 mg/l. This sample has a positive charge balance of 32.30 percent. The sample collected from the packer interval of 270- 295 feet below land surface at Test Site 3 has an overabundance of cations probably caused by grouting and cementing of the packer prior to taking the sample. Since chloride is an anion and not a cation, any error associated with this sample would not effect the validity of the 74 mg/l chloride concentration measured in this sample. This conclusion is also supported by the fact that two samples were collected from the same well at a packer interval of 340-400 feet below land surface with acceptable charge balances and they contained chloride concentrations of 64 mg/l and 134 mg/l. The District’s experts, Richard Burklew and David Toth, believe the 450 mg/l chloride concentration measured in a sample taken from the packer interval of 270-295 feet below land surface at Test Site 3 is a faulty measurement and should be discarded as an outlier. Dr. Toth testified that the sodium to chloride ratio indicates there was a problem with this measurement, which would call into question the reported chloride value. In 2004 and 2005, the City collected SAS water quality samples from Test Sites 4 and 6 and Monitor Wells MW-1 and RW-1 near Test Site 1. The samples were analyzed for all applicable water quality standards, which might preclude use of water from the SAS extraction wells to directly augment wetlands. The analyses found that the SAS water quality near the proposed extraction wells was very similar to the SAS water quality near the Area IV production wells and that water could be applied to the wetlands without any adverse water quality consequences. Area IV UFAS Flow Patterns and Basin Boundaries Although the United States Geologic Survey (USGS) potentiometric surface maps do not show any data points in the vicinity of the proposed Area IV Wellfield, and they are not sufficient by themselves to formulate opinions regarding the future operation or impacts of the proposed wellfield, Petitioners contend that these potentiometric surface maps demonstrate that the freshwater found in the UFAS at the Area IV Wellfield is due to local freshwater recharge only and not freshwater flow from the northwest. They point to a regional report indicating that there is a groundwater basin divide just north of the Area IV Wellfield. This report is based on a 1980 USGS potentiometric surface map. However, another regional report indicates that the groundwater basin divide occurs south of the Area IV Wellfield. This report is likely based on a 1998 USGS potentiometric surface map. Because of the lack of data points in rural northwest Brevard County, the City did not rely on any groundwater basin divide maps, but rather collected site specific information regarding the proposed Area IV Wellfield. The District’s expert and the Petitioners’ own expert (the sponsor of Petitioners' potentiometric surface map exhibits) noted several errors in the flow direction arrows added by Petitioners to the maps. In addition, after reviewing the potentiometric surface maps presented by Petitioners, the District’s expert concluded that, in addition to local freshwater recharge, the predominant flow into the vicinity of the Area IV Wellfield is generally from the northwest and southwest. To confirm his opinion, the District’s expert examined the head difference data collected in July 2006. At well UF-1S, the UFAS observation well at site 1, the elevation in the well was 16.27 NGVD. At site 3, which is southeast of site 1, the elevation in the UFAS observation well was 15.68 NGVD. At site 2, which is southeast of site 3, the elevation in the UFAS well was 13.87 NGVD. Since water generally flows from the highest to lowest head measurements, these measurements indicated that water would have been flowing from the northwest to the southeast in the vicinity of Area IV. However, the potentiometric surface can change both seasonally and yearly; likewise, the basin boundaries may also change. SAS and UFAS Drawdown Predicting drawdown in the SAS and UFAS in the vicinity of the proposed Area IV Wellfield is important to several permitting criteria, including interference with existing legal uses and impacts on wetlands, both of which relate to the public interest. During the permit application review process, the City submitted a succession of models to provide reasonable assurance that the proposed Area IV Wellfield would not result in unacceptable drawdown. Initially, BFA prepared and submitted groundwater flow simulations of the Area IV Wellfield prepared using an analytical model known as the “Multi-Layer/SURFDOWN Model.” Although the District initially accepted the submission as providing reasonable assurance to support the District's initial TSR, Miami Corporation petitioned and criticized the City's model as not actually providing reasonable assurance, both because of its predicted SAS drawdown and because it was an analytical model (which can only represent simple conditions in the environment, assumes homogenous conditions and simple boundary conditions, and provides only a model-wide solution of the governing equation). By comparison, a numerical model allows for complex representation of conditions in the environment, heterogeneous conditions and complex boundary conditions, and cell-by-cell iterative solutions of the governing equation that are typically performed by a computer. Over the past 10 to 15 years, a numerical model called MODFLOW has become the standard in groundwater modeling throughout the United States and much of the world. All of the Florida water management districts utilize MODFLOW or are familiar with it, so it is a model of choice today for groundwater flow modeling. Despite Miami Corporation's petition, the City and the District maintained that reasonable assurance had been given that operation of Area IV would not result in unacceptable drawdown. Miami Corporation's petition was scheduled for a final hearing in June 2005 that was continued until September 2005 after the first revised TSR was issued in May 2005. The final hearing was continued again until February 2006 to allow discovery and hearing preparation by Vergie Clark, who filed her petition in July 2005. As the case proceeded towards a February 2006 final hearing on the pending petitions, the City eventually made what actually was its second attempt to develop a calibrated MODFLOW model of the Area IV Wellfield. Unbeknownst to the District, BFA already had attempted to develop a MODFLOW Model of the Area IV Wellfield in 2004, with the assistance of Waterloo Hydrogeologic, Inc. (WHI) (which later was retained as Petitioners’ consultant in this case in a reverse of the Hartman client switch). When BFA ended its efforts with WHI, their efforts to calibrate a MODFLOW model for Area IV that would predict acceptable drawdown was unsuccessful, and none of those modeling efforts were submitted or disclosed to the District. In the fall of 2005, the City turned to another consultant, SDI, to attempt to develop a calibrated MODFLOW Model of the Area IV Wellfield. SDI initially prepared a so- called MODFLOW model equivalent of the Multi-layer/SURFDOWN Model prepared by BFA. It was presented to District staff at a meeting held in January 2006 for the purpose of demonstrating to District staff that the MODFLOW model equivalent of the Multi- layer/SURFDOWN Model generated results for the Area IV Wellfield that were not very different from the results obtained by BFA using their Multi-layer/SURFDOWN Model. Petitioners criticized several weaknesses in the MODFLOW equivalent model and maintained that the modeling efforts to date did not give reasonable assurance of no unacceptable SAS drawdown. By this time, the District had decided to retain Dr. Peter Huyakorn, a renowned modeling expert. Based on his recommendations, the District required the City to produce a calibrated MODFLOW model of Area IV (as well as numerical solute transport modeling, which will be discussed below). The scheduled final hearing was continued until September 2006 to allow time for this work to be completed, discovered, and evaluated. After the continuance, the City had SDI prepare a calibrated MODFLOW model to predict the drawdown that would result from operation of Area IV. SDI produced such a model in March 2006. This model predicted less drawdown. Specifically, a steady-state simulation of a 2.75 mgd withdrawal from the proposed 15 UFAS production wells and a 0.18 mgd withdrawal from the four proposed SAS extraction/wetland augmentation wells predicted the maximum drawdown of the surficial aquifer to be less than 0.5 foot (which, as discussed infra, would be acceptable). (UFAS drawdown, which is not an issue, was predicted to be an acceptable 12 feet.) But Petitioners questioned the validity of the model for several reasons, including its suspect calibration. Dr. Huyakorn also had questions concerning the calibration of SDI's March 2006 MODFLOW model, but subsequent work by SDI satisfied Dr. Huyakorn and the District, which issued the TSR and proposed CUP at issue in May 2006 based in part on SDI's March 2006 MODFLOW model, despite Petitioners' criticisms. The final hearing was continued until September 2006 to give Petitioners time to complete discovery on SDI's March 2006 MODFLOW model (as well as the City's new solute transport modeling, which is discussed, infra). To calibrate its March 2006 MODLFOW, SDI first used a transient MODFLOW model to simulate data from the 4-day aquifer performance test (APT) from the Area IV Wellfield sites (the transient APT calibration). (A transient model is used to analyze time-dependent variable conditions and produces a time- series of simulated conditions.) Then, after calibrating to the APT data, SDI used a steady-state, non-pumping MODFLOW model (a time-independent model used to analyze long-term conditions by producing one set of simulated conditions) to simulate the static head difference between the SAS and UFAS (the steady- state head difference calibration). If the head difference simulated in the steady-state calibration run did not match the measured head difference, the ICU leakance was adjusted, and then the revised parameters were rechecked in another transient APT calibration run. Then, another steady-state head difference calibration run was performed in an iterative process until the best match occurred for both calibration models. In order to achieve calibration, SDI was required to make the ICU leakance value several times tighter than the starting value, which was the value derived in the site-specific APT using conventional curve-matching techniques (and relatively close to the values ascribed to the region in general in the literature and in two regional models that included Area IV near the boundary of their model domains--namely, the District's East Central Florida (ECF) model, which focused on the Orlando area to the south and west, and its Volusia model, which focused on Volusia County to the north). SDI's calibrated ICU leakance value derived from calibration to observed static head differences is more reliable than an ICU leakance value derived from an APT using conventional curve-matching techniques. That leaves a question as to the quality of the static head difference measurements used for SDI's calibration. BFA took static head measurements at SAS and UFAS monitor wells located at Test Sites 1, 2 and 3 in January 2004, April 2004, and July 2006. On each occasion, a downward head gradient was noted at each site, meaning the water table (i.e., the SAS) had a higher elevation than the potentiometric surface of the UFAS. In January 2004, the measured head difference at Test Sites 1, 2 and 3 were 6.2 feet, 5.5 feet and 5.9 feet, respectively. In April 2004, the measured head differences at Test Sites 1 and 3 were 8.1 feet and 8.1 feet, respectively. In July 2006, the measured head differences at Test Sites 1, 2 and 3 were 8.6 feet, 6.6 feet and 9.3 feet, respectively. The average of these observed head differences for the Area IV Wellfield was 7.46 feet. BFA's static head difference measurements included both wet and dry seasons. The measurements do not show significant differences between seasons and suggest that static head difference remains fairly constant at the Area IV Wellfield year round. This is typical of head difference data collected from hundreds of other Florida locations because the hydrologic systems seek equilibrium. Petitioners questioned taking an average of the head difference measurements because the region had experienced a rainfall deficit of 17 inches over the 12 months prior to time the measurements in July 2006 were taken. By itself, a rainfall deficit would not affect head difference measurements because the hydrologic system would seek equilibrium. But there was evidence of a possibly significant rainfall near Area IV not long before the July 2006 measurements. If significant rain fell on Area IV, it could have increased the static head differences to some extent. But there was no evidence that such an effect was felt by Area IV. Petitioners also contend for several other reasons that the static head differences used by SDI as a calibration target were "not what they are cracked up to be." They contend that "limited spatial and temporal extent . . . renders them inappropriate calibration targets." But while the site-specific static head difference measurements were limited, and more measurements at different times would have increased the reliability of the average static head difference used in SDI's steady-state calibration, the head difference measurements used were adequate. For a groundwater model of Area IV, they were as good as or better than the head differences used by Petitioners' expert modeler, Mr. LaFrenz of Tetratech, who relied on SAS and UFAS head levels from the regional-scale ECF model, which were measured by the United States Geological Survey (USGS) in May and September 1995. Petitioners also contended that the measured head differences used by SDI for the steady-state calibration of the March 2006 MODFLOW model were significantly higher than other measured head differences in the general vicinity of Area IV. One such location is Long Lake, which has saltwater and an obviously upward gradient (i.e., a negative head difference between the SAS and UFAS), whereas SDI's MODFLOW depicts it as having a five-foot downward gradient (positive head difference). However, all but one of those measurements (including from Long Lake) were from locations five or more miles from Area IV. In addition, the accuracy of the measurements from the closer location (and all but one of the more distant locations) was not clear, so that the seemingly inconsistent head differences measurements may not be indicative of actual inconsistency with the head difference measurements used by SDI. Petitioners also accused the City and its consultants of "playing games with specific yield" to achieve calibration with a tighter-than-appropriate ICU leakance value. But the City and the District adequately explained that there was no merit to the accusations. It was appropriate for SDI to use just the relatively small specific storage component of SAS storativity (the 0.001 value) in its transient calibration runs, instead of the larger specific or delayed yield component. Storativity is not utilized at all in the MODLFOW steady-state calibration runs and steady-state simulations. Based on the foregoing, it is found that Petitioners' factual disputes regarding SDI's calibrated ICU leakance value do not make the City's assurance of no unacceptable drawdown provided by its MODFLOW simulations unreasonable. That leaves several other issues raised by Petitioner with regard to the SDI's March 2006 MODFLOW model. In calibrating its MODFLOW model, SDI utilized a value for the MCU leakance that was twice as leaky as the published literature values for the area, which Petitioners claim would reduce simulated SAS drawdown. Although the use of a higher MCU leakance value in the model may result in a prediction of less SAS drawdown, the actual effect, if any, on the predicted drawdown, was not made clear from the evidence. In any event, an MCU leakance value for Area IV calibrated to site-specific data is more reliable than regional values. Petitioners also accused the City and its consultants of using inappropriate or questionable boundary conditions, topography, and depth to the water table. They also contend that incorrect topography--namely, a nonexistent five-foot ridge or mound northwest of Area IV--provides an artificial source of water for SDI's March 2006 MODFLOW model. But the boundary conditions for SDI's March 2006 MODFLOW model were clear from the evidence and were appropriate; and SDI's topography and water table depth were reasonably accurate (and on a local scale, were as or more accurate than the USGS topographic maps Petitioners were comparing). Besides, Dr. Huyakorn ran the Tetratech model with SDI's leakance value instead of Tetratech's value and got virtually the same drawdown results, proving that differences in topography between the two models made virtually no difference to the drawdown predictions of either model. As for the so-called "flow from nowhere," particle-tracking simulations conducted by experts from both sides established that, with pumping at 2.75 mgd, no water would enter the Area IV production zone from anywhere near the five-foot ridge area for at least 100 years. This gave reasonable assurance that the five-foot ridge or mound had no effect on the simulated results from SDI's March 2006 MODFLOW model. Petitioners also contend that the City's failure to simulate drawdown from pumping during the dry season, as opposed to a long-term average of wet and dry seasons, constituted a failure "to provide reasonable assurances as to the conditions that can be expected as a result of the anticipated operation of the wellfields." But the evidence was clear that long-term, steady-state groundwater model simulations are appropriate and adequate to provide reasonable assurance for CUP permitting purposes. See "Drawdown Impacts," infra. By definition, they do not simulate transient conditions such as dry season pumping. The SDI model predicts a maximum drawdown, from a 2.75 mgd withdrawal from all fifteen UFAS production wells and a 0.18 mgd withdrawal from the four SAS extraction wells, of slightly less than 0.5 feet in the SAS and of 12.0 feet in the UFAS in the immediate vicinity of the Area IV Wellfield. SDI’s model predicts a drawdown of 0.11 feet (approximately 1 inch) in the SAS and a drawdown of 2.2 feet in the UFAS at Ms. Clark’s property, which is located approximately 1 to 1.5 miles north of the Area IV Wellfield. It is found that SDI's March 2006 MODFLOW model for Area IV is the best such model in evidence. That is not to say that the drawdown predicted by SDI's model is a certainty. The other models were not proven to be better than SDI's, but they did demonstrate that simulated results would vary significantly in some cases if SDI's calibration and calibrated ICU leakance values were incorrect. Having more good hydrologic information would have made it possible to reduce the uncertainties present in SDI's model, but it is found that SDI's March 2006 MODFLOW model was sufficient to give reasonable assurance as to SAS and UFAS drawdown from pumping at 2.75 mgd from the UFAS and 0.18 mgd from the SAS for wetland augmentation. Drawdown Impacts As indicated, once drawdown is predicted with reasonable assurance, both interference with existing legal uses and impacts on wetlands, which relate to public interest, must be evaluated. Interference with Legal Uses Using SDI's March 2006 MODFLOW model, the City gave reasonable assurance that the drawdown predicted from pumping at 2.75 mgd from the UFAS and 0.18 mgd from the SAS for wetland augmentation will not interfere with existing legal users. The nearest existing legal users are located about one mile northwest and two miles east/southeast of the nearest proposed production well. The City’s MODFLOW modeling scenarios indicate that maximum drawdown in the SAS will be less than 0.5 feet and minimal (at most 2.2 feet) in the UFAS at the nearest active existing legal users. Obviously, drawdown would be much less at 0.5 to 0.75 mgd from the UFAS (with probably no wetland augmentation required). As indicated, the drawdown predicted by SDI's March 2006 MODFLOW model is not a certainty. Although not likely based on the more persuasive evidence, if actual drawdown approximates the drawdown predicted by the Tetratech model, there could be interference with existing legal users. (The Tetratech model predicts that the long-term average reduction in the water table of approximately 1.6 feet of drawdown near the center of the wellfield and drawdown of 0.4 feet to 0.5 feet extending out more than a mile from the proposed Area IV Wellfield.) There probably still would be no interference with existing legal users with pumping at 0.5 to 0.75 mgd from the UFAS (with probably no wetland augmentation required). In the event of that much actual drawdown and unanticipated interference from the City’s pumping, “Other Condition” 15 of the proposed permit requires that it be remedied. See Finding 36, supra. There is no reason to think such interference could not be remedied. Environmental Impacts from Drawdown Miami Corporation’s property in the vicinity of the proposed Area IV Wellfield is a mosaic of pine flatwoods uplands interspersed with wetlands. The wetlands are mostly cypress swamps, with some areas of hardwood swamp, marshes, and wet prairies. Miami Corporation's property is managed for timber and is also used for cattle grazing and hunting. Miami Corporation has constructed a network of roads and ditches on its property, but overall the wetlands are in good conditions. The areas east and west of the proposed Area IV Wellfield consist of cypress strands, which are connected wetlands. Compared to isolated wetland systems, connected wetlands are typically larger, deeper, and connected to waters of the state. They tend to have hardwood wetland species. Connected wetlands are less vulnerable to water level changes brought about by groundwater withdrawals because they tend to be larger systems and have a greater volume of water associated with them. They are able to withstand greater fluctuations in hydroperiods than isolated herbaceous wetland systems. Isolated wetland systems are landlocked systems. They tend to be smaller in size and shallower than connected wetland systems. Isolated systems tend to be more susceptible to changes in hydrology than larger connected systems. The upland plant communities present near the proposed Area IV Wellfield include pine flatwoods that have been altered by Miami Corporation's timber operations. There is a large area surrounding the Area IV Wellfield to the north that consists of forest regeneration after timbering. There was evidence of the presence of the following listed animal species at the site of the proposed Area IV Wellfield: wood storks, roseate spoonbills, ibis, bald eagles, Sherman fox squirrels, American alligator, sandhill cranes, wood storks, black bear, and indications of gopher tortoises. The habitat in the vicinity also supports a number of other listed species that were not observed. The following listed plants species were also observed during the environmental assessment and site visits: hooded pitcher plants, water sundew, pawpaw and yellow butterwort. Ms. Clark’s property adjoins a cut-over cypress swamp on the western side of her property, and there is also a small man-made fish pond in her backyard. Some clearing has taken place in the wetland system on the back portion of Ms. Clark’s property. What appears to be a fire break on Ms. Clark’s property encroaches upon the wetland system. The wetlands on Ms. Clark’s property have experienced some human activities such as trash dumping and clearing, which have resulted in a degradation of those systems. Some trees within the wetland systems on the back portion of Ms. Clark’s property have been logged. For the most part, the hydrology appears to be normal. However, some invasive species have encroached upon the system due to the clearing that has taken place. There was no evidence of listed plant or animal species present on Ms. Clark’s property. If drawdown is of the magnitude predicted by the SDI's March 2006 MODFLOW model, unacceptable environmental impacts from drawdown would not be anticipated. At 0.5 or 0.75 mgd, there clearly would not be any unacceptable environmental impacts. In addition, “Other Condition” 12 of the proposed permit requires the City to perform extensive environmental monitoring. The environmental monitoring plan proposed for the Area IV Wellfield provides reasonable assurance that changes to wetland hydrology and vegetation due to groundwater withdrawals will be detected before they become significant. “Other Condition” 12 of the proposed permit prohibits the City from pumping any water from the production wells until the monitoring network is in place. The baseline monitoring will give a clear indication of the existing conditions prior to the production wells coming on-line. Once the production wells are online, the City will continue the same procedures that they conducted prior to the production wells coming online. This will allow the City and the District to monitor the effects of pumping. The City’s proposed environmental monitoring plan is adequate to detect drawdown impacts and is consistent with environmental monitoring plans that have been developed for other wellfields throughout the State of Florida. Since the City has given reasonable assurance that there will not be environmental harm from drawdown, the proposed permit does not propose mitigation. If unanticipated harm is detected, “Other Condition” 24 of the proposed permit requires the City to implement an avoidance and minimization plan to rehydrate the wetlands and restore the water levels to normal levels and natural hydroperiods by augmenting the water in the affected wetlands with water pumped from SAS wells and piped to the affected wetlands. “Other Condition” 24 includes specific timeframes for implementing wetland rehydration in the event unanticipated impacts were to occur. In addition, the City could, on its own, change its pumping schedules. If an impacted wetland is near a particular well, the City could reduce or shut off water withdrawals from that well and thereby restore water levels in the wetland. Direct augmentation of wetlands has been used at other facilities such as those of Tampa Bay Water and Fort Orange. The direct augmentation at these other sites appears to be effective. Direct augmentation of wetlands has proven to be a feasible means of offsetting adverse changes in wetlands due to groundwater withdrawals, at least in some circumstances. There is a viable source of water that can be utilized to augment these wetland systems, namely a large canal south of the production wells. Based on the predicted drawdown, SDI estimated the quantity of water needed for implementation of the avoidance and minimization plan to be 0.18 mgd. The water quality in the canal is comparable to the water quality within any wetland systems that would be affected by drawdown. The City plans to have its augmentation plan in place prior to the production wells coming online. In that way, if changes are observed within the wetland systems, the augmentation plan could be implemented in relatively short order to alleviate any impacts that might be occurring as a result of the production wells. The success of the augmentation plan depends on the extent of actual drawdown. If actual drawdown approximates Tetratech's predictions, environmental impacts would not be acceptable, and there would not be reasonable assurance that the augmentation plan would be sufficient to mitigate the environmental impacts. If drawdown is of the magnitude simulated in the City’s MODFLOW model, reasonable assurance was given that, if needed, the avoidance and minimization plan developed for the Area IV Wellfield would be capable of offsetting any adverse changes in wetlands and other waters detected through the environmental monitoring plan. If the City pumps not more than 0.75 mgd, the avoidance and minimization plan developed for the Area IV Wellfield probably would be unnecessary but certainly would be capable of offsetting any adverse changes in wetlands and other waters that would be detected through the environmental monitoring plan. If unanticipated environmental harm occurs due to excessive actual drawdowns, and the harm cannot be avoided either by the augmentation plan or by altering the pumping schedule, or both, the District can revoke all or part of the permit allocation under “Other Condition” 23. This ability gives reasonable assurance that no unacceptable environmental harm will occur even if actual drawdown approximates Tetratech's predictions. Saltwater Up-coning and Intrusion Predicting saltwater movement towards the production zone of the proposed Area IV Wellfield is important to several permitting criteria, including interference with existing legal uses and the ability of the resource to provide the requested allocation of freshwater, both of which relate to the public interest. During the permit application review process, the City submitted a succession of models to provide reasonable assurance that the proposed Area IV Wellfield would not result in unacceptable saltwater intrusion. Initially, BFA prepared and submitted solute transport simulations using an analytical model known as the “UPCONE Model.” The District initially accepted the submission as providing reasonable assurance to support the District's initial TSR. Despite Miami Corporation's petition, the City and the District maintained that reasonable assurance had been given that operation of Area IV would not result in unacceptable saltwater intrusion based on the "UPCONE Model." As indicated, supra, Miami Corporation's petition was scheduled for a final hearing in June 2005, but the hearing was continued until February 2006. As the case proceeded towards a final hearing in February 2006, the City not only turned to SDI to develop the numerical MODFLOW model, it also turned to SDI to develop a numerical solute transport model that would couple the MODFLOW groundwater flow equations with advection dispersion solute transport equations to simulate the movement of variable density saline groundwater in response to stresses. In addition to the initial boundary conditions, aquifer parameters and stresses specified for a groundwater model, a solute transport model requires solute parameters such as chloride concentrations, dispersivity and effective porosity. SEAWAT is a solute transport model code that combines the MODFLOW, which provides the groundwater flow component, with the MT3DMS code, which provides the mass transport component. When coupled with MODFLOW, the MT3DMS code tracks the movement of variable density water and performs internal adjustments to heads in the flow model to account for water density. Like MODFLOW, SEAWAT is capable of simulating the important aspects of the groundwater flow system, including evapotranpiration, recharge, pumping and groundwater flow. It also can be used to perform both steady-state or transient simulations of density- dependent flow and transport in a saturated zone. It was developed in the late 1990s and is rapidly becoming the standard for solute transport modeling throughout the United States. It is used by many water management agencies in the State of Florida. Initially, SDI used SEAWAT version 2.1 to simulate movement of saline water towards the Area IV Wellfield. The first such simulation was prepared in March 2006 using manually- adjusted head values along the eastern model boundary. It incorporated SDI's March 2006 MODFLOW model. The District, in consultation with Dr. Huyakorn, required SDI to perform what was termed a "sensitivity run" with reduced chloride concentrations in the eastern boundaries (5,000 mg/l versus 19,000 mg/l) to better match actual measurements recorded in wells in the vicinity. In April 2006 SDI prepared and submitted those simulations. After reviewing the March and April 2006 SEAWAT 2.1 simulations, Petitioners' consultants criticized the manner in which starting chloride concentrations in the vicinity of the Area IV Wellfield were input into the models. In those models, SDI had input initial chloride concentration at 50 mg/l throughout the depth of the UFAS. The model was then run for 100 years with no pumping to supposedly arrive at a reasonable starting chloride concentration for the UFAS. Then, the model was run for 25 years with pumping at 2.75 mgd. However, the initial chloride concentrations at the beginning of the pumping run still did not comport well with actual measurements that were available. After Petitioners raised the issue of the starting chloride concentrations assigned to the UFAS in SDI's March and April 2006 SEAWAT 2.1 runs, the final hearing was continued until September 2006 to give Petitioners time to complete discovery on those models (as well as on SDI's March 2006 MODFLOW model, as discussed supra). During a deposition of Dr. Huyakorn in July 2006, he recommended that the District require SDI to perform another simulation (also termed a "sensitivity run") using starting chloride concentrations more closely comporting with known measurements. (There also were some changes in the constant chloride concentrations that were part of the boundary conditions on the western side of the model domain.) This resulted in SDI's early August 2006 SEAWAT 2.1 simulation of 15 years of pumping at 2.75 mgd. Petitioners also criticized the City for not using a newer version of SEAWAT, called SEAWAT 2000, as well as for using chloride concentrations as inputs for its SEAWAT 2.1 model simulations instead of total dissolved solids (TDS). (SEAWAT 2.1 required input of TDS, not chlorides; SEAWAT 2000 allowed chlorides to be input. Not until the last day of the final hearing was it pointed out by Dr. Huyakorn that using chlorides instead of TDS caused SDI's SEAWAT 2.1 simulations to over- predict saltwater intrusion.) As a result of Petitioners' criticisms, the City had SDI re-run both the April and early August SEAWAT 2.1 models in late August 2006 using SEAWAT 2000 (which the City and the District also termed "sensitivity runs.") Because the SEAWAT 2000 simulations would be time- barred from use in the City's case-in-chief under pre-hearing requirements, and whether they could be used in rebuttal could not be determined at that point in time, the City requested another continuance, this time until December 2006, to give Petitioners time to discover the SEAWAT 2000 model simulations. During Petitioners' discovery of SDI's August SEAWAT 2000 model simulations, it came to SDI's attention that SDI was not calculating mass outputs from the model correctly. Those errors were corrected by SDI in September 2006. SDI's corrected August 2006 SEAWAT 2000 simulation predicted that, after 15 years of pumping at 2.75 mgd, the chloride concentration in the Area IV production wells would increase from 54 mg/l to 227 mg/l. After the 15-year pumping run, SDI's corrected August 2006 SEAWAT 2000 simulation predicted that the chloride concentration in several of the southernmost production wells would exceed 250 mg/l. At 17.5 years of the pumping run simulation, the simulation predicted that the entire wellfield would have chlorides in excess of 250 mg/l. That prediction does not, however, mean the chloride concentration in these wells will exceed 250 mg/l in actual operation. The SDI model contains several conservative assumptions that magnified the potential chloride concentrations in those wells. First, it was assumed all the production wells would be drilled to 250 feet below land surface, while the City will likely drill the southernmost wells to a shallower depth. Additionally, the wellfield production rate used in the model was not optimized for water quality. Finally, the model was not set up to simulate a wellfield operation plan that turned wells on and off based on the saline water monitoring plan. For the sake of simplicity, the model assumed that all the wells would operate 24 hours a day, 7 days a week, for the entire 15 year period. Petitioners continued to maintain for several reasons that SDI's SEAWAT models do not provide reasonable assurance that operation of the Area IV Wellfield will not result in unacceptable saltwater intrusion. Chlorides versus TDS Petitioners criticized SDI's corrected SEAWAT 2000 model for still not inputting chlorides correctly. While SEAWAT 2000 allows the input of chlorides instead of TDS (and input of chlorides instead of TDS is recommended since chloride is a more stable chemical than some of the other components of TDS), they must be input correctly. However, while Petitioners demonstrated that the chlorides were not input correctly, causing the model to under-calculate fluid density, Dr. Huyakorn clarified in rebuttal that under-calculating fluid density caused SDI's SEAWAT 2000 models to over-predict saltwater intrusion into the wellfield. Starting Chloride Conditions Petitioners continued to question the representation of initial chloride concentrations in the SEAWAT models. SDI's SEAWAT models included multiple vertical grid layers to represent conditions better than the layering used in the MODFLOW set-up. The SAS was represented by layer 1, the ICU by layer 2, the UFAS by layers 3 through 14, the MCU by layer 15, and the LFAS by layers 16 and 17. SDI used a chloride concentration of 0 mg/l for the SAS and ICU in its August 2006 SEAWAT model, which probably does not represent the actual initial condition but is probably close enough since the SAS is recharged by rainfall that typically has very low (1 to 2 mg/l) chloride levels. SDI used a chloride concentration of 2,500 mg/l for the MCU and a chloride concentration of 5,000 mg/l for the LFAS in its August 2006 SEAWAT model, which are reasonable initial chloride values for the Area IV Wellfield. To develop the initial chloride concentration conditions of the UFAS for its August 2006 SEAWAT model, SDI first plotted the available water quality data (63 well-data points) on a map of the Area IV Wellfield area. After examining the distribution of the data, SDI divided the UFAS into two layers to represent the upper UFAS (above –200 feet NGVD) and the lower UFAS (below –200 feet NGVD). Then, using various scientific studies containing chloride concentration maps, groundwater recharge/discharge maps (recharge indicating an area is more likely to have low chlorides in the UFAS and discharge indicating an area is more likely to have high chlorides), and maps showing the shape and extent of the freshwater lens in the area, plus SDI’s own knowledge of groundwater flows and expected higher chloride concentrations along the coast and St. Johns River, SDI used scientifically accepted hand-contouring techniques to represent the initial chloride concentration conditions of the upper and lower UFAS on maps. SDI’s two hand- contoured chloride concentration maps were reviewed and accepted by the District’s experts and reflect a reasonable representation of the initial chloride concentration conditions in the UFAS in the Area IV Wellfield. Using the two hand- contoured chloride concentration maps, SDI input the chloride concentration values from those maps into its August 2006 SEAWAT model. The chloride concentration values from the upper UFAS map were input into layers 3 through 7 of SDI’s August 2006 SEAWAT model. The chloride concentration values from the lower UFAS map were input into layers 11 through 14 of SDI’s August 2006 SEAWAT model. SDI input the average of the chloride concentration values from the upper and lower UFAS layers into the middle UFAS (layers 8 through 10). It is appropriate to average the chloride values between the upper and lower UFAS in the Area IV Wellfield because the saline water interface is not that sharp and occurs near the bottom of the UFAS (unlike conditions 11 miles to the south). Petitioners accuse SDI, the City, and the District of ignoring unfavorable chloride data in setting up its August 2006 SEAWAT 2000 model. The evidence was that all chloride data was considered and evaluated. Mr. Davis and the District's experts did not rely on the 450 mg/l chloride packer test measurement taken from the interval between 270 and 295 feet at Test Site 3 in preparing the contour maps of the UFAS because the chloride measurement was deemed inaccurate because the sodium to chloride ratio is out of balance. Mr. Davis and the District's experts did not utilize the 2,336 mg/l and 2,717 mg/l chloride concentration packer test measurements at 442-500 feet below land surface at Test Sites 1 and 3 to prepare the chloride contour maps for the UFAS because they believed these measurements from the MCU. Mr. Davis and the District's experts deemed it inappropriate to utilize a 845 mg/l chloride value reported for Test Site 2 to prepare the chloride contour for the lower portion of the UFAS because this sample was collected at just 210 feet below land surface and because a 500 mg/l contour line separates a 882 mg/l measurement at Test Site 1 from a 134 mg/l measurement at Test Site 3. The decision not to include the Test Site 2 data also is supported by the particle tracking modeling prepared by the Petitioners and the City using the groundwater component of the SDI SEAWAT model and the TetraTech model, which show that water from Test Site 2 will not enter the Area IV production wells for at least 100 years with pumping at 2.75 mgd. The chloride contour maps developed by Mr. Davis and the District experts were consistent with previous studies conducted by the USGS and the District in the region. For example, the chloride contours shown on City Exhibit 142 for the upper portion of the UFAS are generally consistent with Figure 35 of the 1990 USGS Report by Charles Tibbals and Figure 15 of the 1999 District Report by Toth and Boniol. The two chloride contour maps developed by Mr. Davis and the District's experts are a reasonable representation of the existing water quality of the UFAS in the region of the Area IV Wellfield based on the available data. Mr. Davis used the 882 mg/l chloride concentration packer test measurement from the interval between 331 and 400 feet at Test Site 1 as the starting chloride concentration in four grid cells at the bottom of the UFAS, which Petitioners' experts referred to as a "pinnacle" or "column," that were assigned a chloride value of 700 mg/l. While the representation may not have been realistic, and the "pinnacle" or "column" quickly "collapses" when the model begins to run, the representation was a concession to the existence of the datum even though it appeared at odds with water quality collected from a packer test at Test Site 3 at the same depth interval, which was much fresher. District staff agreed with Davis’ approach to representing the saltier packer test measurement from Test Site 1. The initial chloride concentrations developed for the UFAS by Mr. Davis and District staff are not inconsistent with the water quality data collected by the Petitioners’ consultants from Long Lake. The lake is located in an area of the map where the chloride concentration in the UFAS, which discharges into the lake at that location, is between 1,000 and 5,000 mg/l. Mr. Davis decided not to use 2,000 mg/l to represent the bottom layer of the UFAS even though the bottom packer tests performed at Test Sites 1 and 3 showed an average value of 2,000 mg/l at the approximate boundary of the UFAS and the MCU. Instead, he decided to associate this chloride concentration with the MCU because even if the packer had penetrated a portion of the UFAS, he did not believe the measurement was representative of static water quality conditions at that depth. The packers had been pumped for over 4 hours at 25 gpm at Test Site 1 and over 4 hours at 85 gpm at Test Site 3, which could have doubled or tripled the static chloride concentration. As was later shown in sensitivity runs by Petitioners' expert, Dr. Guo, if SDI had incorporated the 2,000 mg/l value at the bottom of the UFAS, the model simulation would have shown unrealistically high initial chloride concentrations in the production wells at the start of pumpage when compared to the water quality measured during the APTs conducted at Test Sites 1 and 3. (While only one well was pumping at a time, versus the 15 in the model simulations, the single APT well was pumping at approximately three times the rate of the 15 wells in the model simulation.) Based on all the evidence, it is found that the chloride concentrations used in SDI’s August 2006 SEAWAT model reflect a reasonable representation of the initial chloride concentration conditions in the UFAS in the Area IV Wellfield and were properly input into that model using an appropriate method. Location of the MCU Related to the last point is Petitioners' claim that the top of the MCU (i.e., bottom of the UFAS) is incorrectly represented in SDI's SEAWAT models at 450 feet below sea level (approximately 425 feet below land surface). They point to literature values indicating that the depth to the MCU is up to 150 feet greater. However, these reports did not include site- specific data or test wells in the vicinity of the Area IV Wellfield or in northern Brevard County. It was reasonable to consider and rely on site-specific information regarding the depth to the MCU in this case. BFA determined the approximate location of the MCU by examining cuttings collected during drilling at APT well sites 1 and 3 and by measuring various properties of the aquifer with down-hole geophysical techniques. Based on the site-specific information obtained, the depth to the MCU was determined to be approximately 450 to 475 feet below land surface or –425 to -450 feet NGVD. The lithologic log for well site 1 indicates the presence of gray/tan limestone between 450 to 460 feet below land surface and light/gray limestone and dolomitic limestone from 460 to 470 below land surface. The lithologic log for well site 3 indicates the presence of tan dolomitic limestone from 450 to 460 feet below land surface and tan limestone and dolomitic limestone from 460 to 470 feet below land surface. According to Petitioners' own expert, Dr. Missimer, the change to a mixture of limestone and dolomite is evidence of the MCU. After examining the video log for well site 1, Dr. Missimer noted a “lithologic change” at 477 feet below land surface (while still disputing BFA's conclusion that the MCU started there.) One characteristic of the MCU is a lower resistivity. At well site 1, a reduction in resistance occurred at approximately 470 feet below land surface. Another characteristic of penetrating the MCU is decrease in flow. The flow meter log for well site 1 suggests a decrease in flow at approximately 450 feet below land surface. On the other hand, it also is true that wells drilled completely into the MCU probably would not produce more than approximately 5 gallons per minute (gpm), whereas the packer test at the bottom of Wellsite 1 was yielding 25 gpm, and the packer test at the bottom of Wellsite 3 was producing 85 gpm. It is possible that the bottom packers were open to both the UFAS and the MCU, which could explain the higher flows. Petitioners maintain that BFA stopped drilling too soon (500 feet below land surface, or 475 feet below sea level) to ascertain the actual depth to the MCU. While it is true that drilling deeper would have made BFA's determination as to the depth to the MCU more convincing and certain, BFA's approximation of the depth to the MCU was reasonable for purposes of SDI's SEAWAT model. To the extent that BFA might have been wrong on the depth to the MCU, there was no convincing evidence that the error would have made SDI's SEAWAT model results unreliable. To the contrary, Dr. Huyakorn testified that, even if SDI put the MCU 75 feet too high, the label given to the interval is not critical to the reliability of the modeling results. More important are the parameters for transmissivity and leakance assigned to aquifers and confining units. Dr. Huyakorn testified that, given the aquifer parameters assigned to the intervals, SDI's SEAWAT modeling results would be reasonably reliable. Saline Movement Impacts As indicated, once chloride concentration changes are predicted with reasonable assurance, both interference with existing legal uses and the ability of the resource to provide the requested allocation of freshwater, which relate to public interest, must be evaluated. Significant saline water intrusion is defined as saline water encroachment which detrimentally affects the applicant or other existing legal users of water, or is otherwise detrimental to the public. (Rule 9.4.2, A.H.). Saline water may encroach from upconing or the vertical movement of saline water into a pumping well, and it may encroach laterally to the well from a saline waterbody like the ocean. The proposed use associated with the four surficial aquifer extraction wells is so minimal that it clearly would not cause saline water intrusion or harm the quality of this proposed source of water. The focus of attention is the production wells. The evidence was sufficient to provide reasonable assurance that the proposed consumptive use from the Area IV Wellfield will not cause significant saline water intrusion; further aggravate currently existing saline water intrusion problems; induce significant saline water intrusion to such an extent as to be inconsistent with the public interest; or harm the quality of the proposed source of water. First, the long-term constant rate pump tests, which were conducted as part of the APT, give some indication of the potential for saltwater intrusion. While only one well was pumping during the tests, water quality did not degrade at pumping rates that far exceeded what would be approved as part of the proposed permit. During four-day pump tests in which the wells at sites 1 and 3 were pumped at approximately 1 mgd, chlorides never exceeded approximately 74 mg/l. Second, while (as with drawdown predicted by the groundwater flow modeling) saltwater movement predicted by the City’s SEAWAT simulations is not a certainty, the simulations gave reasonable assurance that the requested allocation could be withdrawn from the Area IV Wellfield without excessive changes to water quality (specifically chlorides) and that there is an adequate thickness of freshwater at the Area IV Wellfield that could supply the requested allocations of water for 15 years without saline water intrusion, especially since it is unlikely that a number of the wells will actually be constructed to the 250-foot depth assumed in the model, particularly as one moves south along the railroad right-of way. Third, it is even more unlikely that saltwater intrusion will occur before the proposed permit expiration in 2010. Due to the time required to construct the facility, it is anticipated that the Area IV Wellfield will become operational in 2009. Assuming the City seeks to renew the permit, there would be more information on saltwater intrusion for the District to consider on permit renewal. Since the City provided reasonable assurance as to its proposed withdrawals from Area IV, there clearly is reasonable assurance that withdrawal of not more than 0.75 mgd from Area IV would not result in significant saline intrusion. The TSR includes proposed “Other Condition” 11 which requires the installation of saline monitor wells. The spatial distribution of these wells is such that the beginning of water quality degradation or saltwater intrusion, either from upconing or lateral intrusion, would not occur without it being detected by these wells. In addition to these monitor wells, proposed “Other Condition” 14 requires water quality samples to be collected from each production well. These wells are to be sampled quarterly for a suite of parameters, including chlorides. “Other Condition” 25 is proposed as a “safety net” should unanticipated saltwater intrusion occur. If any production well shows a concentration of 250 mg/l chlorides, then this proposed condition would prohibit further use of the well until the chloride concentration drops. If the monitoring shows a chloride concentration in a production well of 200-to- 249 mg/l, the well will be placed on restricted use. A production well may be placed back into regular service once the chloride concentration in the well is below 200 mg/l. Other Issues Other issues raised and maintained by Petitioners in this case include: whether the City has provided reasonable assurance that it owns or controls the property upon which the proposed wellfield will be located; whether the Area IV Wellfield is an economically feasible option; whether the City has provided reasonable assurance that it will be able to implement the project before the expiration date of the proposed permit; whether the proposed CUP is inconsistent with the District's designation of Priority Water Resource Caution Areas; whether the proposed CUP constitutes an impermissible modification of the existing CUPs for Areas II and III; and whether the City failed to pay the appropriate permit fee. Ownership or Control The City has obtained an easement from the Florida East Coast Railway (FEC) to use FEC right-of-way for the City's proposed production wells. It does not yet have ownership or control of land needed for all wetland and saline monitoring sites, or for wetland augmentation if necessary, but intends to acquire the right to use all land needed through negotiation or exercise of eminent domain. Petitioners contend that the FEC easement is insufficient for several reasons: the easement is "without warranty or covenants of title of any kind"; it is impossible to define the precise boundaries of the easement because the easement is defined in terms of distance from the center of a railroad bed that existed in 1866 but no longer exists; and the precise location of proposed production wells is not definite. While the easement is "without warranty or covenants of title of any kind," the evidence is that, if contested, the precise boundaries of the easement would be difficult but not necessarily impossible to define. It is reasonable to anticipate that at least Miami Corporation will contest the legality and extent of the FEC easement. Petitioners allege that there is confusion about the location of the proposed wells because some well locations identified in the City’s permit application did not match the coordinates assigned to certain production wells on the District’s on-line database. Actually, there is no confusion regarding the location of the wells; the well locations identified in the permit application were the well sites used for modeling purposes and for review of the application. District staff explained that the well site locations identified in the District’s database would be finalized after the wells are constructed and the exact locations have been identified using GPS technology. Contrary to Petitioners' contentions, the District’s rules do not require that an applicant own the property where the proposed production wells or monitoring wells are to be located. The District has issued many CUPs where either the subject property or the property associated with the monitoring requirements of the permit are not owned by the applicant. Recent examples include the CUPs for Orange County Utilities and the Orlando Utilities Commission. This makes sense when the applicant has the power of eminent domain or some other credible means of obtaining necessary ownership or control, such as an option contract. The District’s permit application form has a section that requires the applicant to identify who owns or controls the land on which the facility will be located. The District uses this information for noticing and contact information. Contrary to Petitioners' contentions, this section of the permit application form is not intended to create a substantive permitting standard requiring property ownership before a consumptive use permit can be issued. Petitioners argue that proof of ownership or control is necessary to determine whether a drawdown from a proposed water use will adversely affect stages or vegetation on lands other than those owned, leased, or otherwise controlled by the applicant. However, the evidence was that these impacts can be assessed based on the facts of this case. The City's need to eventually obtain ownership or legal control to exercise the rights granted by the proposed CUP may be problematic in this case and is a factor to be considered in the next two issues raised and maintained by Petitioners: whether the Area IV Wellfield is an economically feasible option; and whether the City has provided reasonable assurances that its project can become operational before the expiration date of the proposed permit. But it is not a reason to automatically deny the City's proposed CUP. Economic Feasibility Petitioners argue that the proposed Area IV Wellfield is too expensive and that the expense should be a factor in deciding whether it is in the public interest. But cost to the City is not a factor in determining whether to issue the CUP proposed in this case. Statutes and rules cited by Petitioners on this point do not apply to this CUP determination. See Conclusions of Law 277-279, infra. Implementation Before Expiration Date Litigation of a case filed by Miami Corporation to contest the legality and extent of the City's FEC easement will add to the (cost and) time necessary to implement the project. This additional time was not specifically taken into account by the City in estimating the time it would take to implement the project. The (cost and) time for litigation of the legality and extent of the City's FEC easement could be spared by exercising eminent domain instead. That probably would add to total the cost of eminent domain but might not add appreciably to the time necessary for acquisition of required ownership or control. In an imprecise way, the time for eminent domain proceedings necessary to gain ownership or control of land for monitoring sites and wetland augmentation (without time for litigation of a contest over the legality and extent of the FEC easement, or for using eminent domain instead) was factored into the time estimated for implementation of the project. With this rough estimate, the evidence was that the project could be expedited and completed in 33 months from issuance of a CUP. It is possible but not probable that the project could be implemented in less than 33 months. It is possible and more probable that it will take longer than 33 months to implement the project. In a worst case scenario, it could take as much as 59 months complete the project. But 33 months is a reasonable, if optimistic, estimate (without time for litigation of the legality and extent of the FEC easement, or for using eminent domain instead). As found, the proposed CUP expires at the end of 2010. Given the 33-month estimate for implementation (without time for litigation of a contest over the legality and extent of the FEC easement), the CUP would have to be issued by March 2008 to be completed before expiration. Given that estimate, it would be in operation for six months before expiration. It is likely that the City will apply to renew both the existing CUP for Areas II and III and the proposed CUP for Area IV. It appears from Petitioners' Response to the other PROs that one purpose for their arguments that the proposed CUP for Area IV cannot be implemented before its expiration is to buttress their arguments, already addressed, that there is no need for the proposed CUP for Area IV. Priority Water Resource Caution Area Designation As part of its water supply planning process, the District designates priority water resource caution areas. A priority water resource caution area is an area where existing and reasonably anticipated sources of water and water conservation efforts may not be adequate to supply water for all existing legal uses and anticipated future needs and to sustain the water resources and related natural systems. The area surrounding the Area IV Wellfield was designated as a priority water resource caution area in the District’s 2003 Water Supply Assessment and 2005 Water Supply Plan based on groundwater modeling prepared by District planning staffing using the ECF and Volusia County Regional Models. The fact the Area IV Wellfield is located in a priority water use caution area does not mean a consumptive use permit cannot be issued for this facility. In fact, over one- third of the District is located within a priority water resource caution area, and permits continue to be issued in those areas. Rather, the essence of the designation is the recognition of a concern, based on the regional models, that the proposed consumptive use of water might violate the wetland and lake constraints and that water resources other than fresh groundwater will be needed to supply the expected need for water in the area and in the District over the next 20 years. That does not mean that no additional groundwater withdrawals should be permitted in a designated area. Rather, it means that other resources should be developed and used along with whatever remaining additional fresh groundwater can be permitted. It is not an independent reason, apart from the permitting criteria, to deny the City's application. Impermissible Modification of Existing CUP Petitioners contend that the proposed CUP for Area IV includes an impermissible modification of the existing CUP for Areas II and III because “Other Condition” 5 limits average annual withdrawals from the Area II, III, and IV Wellfields, combined, to 5.79 mgd in 2009 and 6.01 mgd in 2010. (As indicated, the limitations would have to be reduced to no more than 5.2 mgd based on the more reasonable projected need.) However, the City’s current CUP for the Area II and III Wellfields expires in February 2008, which is before the Area IV Wellfield would become operational, so that "Other Condition" 5 will have no practical effect on the existing CUP for Areas II and III. In essence, "Other Condition" 5 serves to advise the City that it should not view the allocation for the Area IV Wellfield in addition to the City’s existing allocations for the Area II and Area III Wellfields and that any renewal of the existing CUP for Areas II and III will have to take the Area IV allocation into account. Appropriate Permit Fee Petitioners have alleged that the City has not paid the correct permit processing fee. In March 2001, the City paid the District $200 when it submitted its initial permit application to modify its existing CUP. In May 2005, the City paid the District an additional $800 when it amended its application and withdrew its request to modify its existing permit. All required permit processing fees have been paid for this CUP application 99052. Miscellaneous As to other issues raised by Petitioners in the case, the evidence did not suggest any danger of flooding, any proposed use of water reserved by rule for other uses, any effect on any established minimum flows or levels, or inadequate notice. Standing As found, Miami Corporation owns property immediately adjacent to the proposed Area IV Wellfield, and Ms. Clark owns property a little more than a mile away. Both alleged and attempted to prove that SAS drawdown from the proposed CUP would degrade wetlands on their property and interfere with their legal use of groundwater, and that saline intrusion from the proposed CUP would degrade the water quality of the UFAS resource which they use for potable water. As found, Petitioners did not prove those allegations; however, the evidence was that both Petitioners have substantial interests (the quality of water in the aquifer from which their wells withdraw water and wetlands on their property) that would be affected by the proposed CUP at least to some extent.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the District issue the City a CUP for Area IV as provided in the second revised TSR, except for a lower water allocation at this time, namely: 0.75 mgd on an annual average basis, with appropriately lower allocations on the other bases in the TSR, and with a combined annual average rate for Areas II, III, and IV in "Other Condition" 5 of 5.2 mgd for 2009 and 2010 instead of 5.79 mgd in 2009 and 2010, and appropriately lower combined maximum daily rates for Areas II, III, and IV in "Other Condition" 9. Jurisdiction is reserved to hear and rule on the pending motions for sanctions if renewed no later than 30 days after entry of the final order in this case. DONE AND ENTERED this 31st day of July, 2007, in Tallahassee, Leon County, Florida. S J. LAWRENCE JOHNSTON Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 31st day of July, 2007.
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.

"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.

Findings Of Fact Petitioner Thomas G. Allderdice owns approximately eleven acres of land which is located between Julington Creek Road and Julington Creek in Jacksonville, Florida. On April 2, 1979, he filed an application with Respondent Department of Environmental Regulation's St. Johns River Subdistrict Office at Gainesville for a permit to fill approximately one quarter acre at the southeast corner along the creek for a homesite. (Testimony of Petitioner, Petitioner's Exhibits 2, 7-8) Petitioner intends to fill the site to a height of approximately three feet, utilizing clean sand obtained from a commercial sand company. His application originally reflected an intent to surround the filled area with logs, but after being advised by John Gray, City of Jacksonville Engineering Office, that he would not need a city permit if he used riprap instead of logs along the shoreline, he modified his application and now intends to use masonry rubble riprap for approximately 120 feet along the bank which will extend some three to four feet into the water. The sketch attached to Petitioner's application describes the riprap as a "proposed silt barrier," but indicates that it will be placed at present ground level. (Testimony of Petitioner, Petitioner's Exhibit 8) On April 4, 1979, Respondent notified Petitioner that the application was incomplete in several respects, including the necessity of obtaining evidence as to local approval of the project. Subsequently, on August 28, and December 10, Petitioner was advised by letters from the St. Johns River Subdistrict that his application was incomplete in that respect. Finally, on January 25, 1980, the subdistrict manager issued a Notice of Intent to Deny the application pursuant to Chapters 253 and 403, Florida Statutes, and Public Law 92-500, for (a) failure to respond to the request for additional information, (b) potential water quality degradation by replacing an aquatic ecosystem with a residential homesite, and (c) various reasons whereby the project would be adverse to the public interest, as specified in Chapter 253, Florida Statutes. Petitioner thereafter requested a hearing in the matter. (Testimony of Rector, Scott, Respondent's Exhibits 2, 4-5) The land in question is located on the north side of Julington Creek. Julington Creek is a typical fresh water tributary of the St. Johns River. Both sides of the creek have been moderately developed for residential use. The site in question may be described as a flood plain forest in the nature of a swamp that is inundated periodically during periods of high waters. Various small sloughs along the irregular shoreline extend into the property for several feet. The forest canopy is dominated by ash, cypress, blackgum and and maple with Florida elm, sweetgum and laurel oak growing on elevated hummocks. Throughout the region, the sparse ground cover includes iris, royal fern, lizard's tail, wild taro, buttonbush, and young cabbage palm. The littoral areas waterward of the proposed fill site are dominated by spatterdock, alligator weed and cattails. The area near the shore contains tupelo, cypress, and ash. These species which are associated with hardwood swamps fall within those listed in Rule 17-4.02(17)and (19), Florida Administrative Code, which constitute the dominant plant community of "submerged lands" and the transitional zone of a submerged land. Although Petitioner established that on two occasions in April 1980 during high tides, the land was not submerged, the area was flooded during a visit on September 17, 1979, by Respondent's subdistrict dredge and fill permit supervisor. At that time, the high tide was slightly over one foot above normal. On another occasion, a biologist for the Florida Game and Fresh Water Fish Commission observed that the site was inundated to a degree of approximately 20 percent. (Testimony of Petitioner, McCormick, Barber, Scott, Cox, Petitioner's Exhibit 3, 4-6, Respondent's Exhibits 1, 6) Julington Creek is classified as a Class III body of water. The swamp wetlands of the site serve as feeding, nesting, nursery, and refuge habitat for a variety of fish during inundation. The forest area contributes to fishery productivity by supplying a natural source of organic matter to the aquatic food web and serves to protect water quality from degradation by filtering sediments, nutrients, and other pollutants from upland runoff. The placement of fill at the proposed site will result in the loss of a high quality habitat of valued fish and wildlife resources which is a natural water quality treatment system. (Testimony of Barber, Scott, Cox, Respondent's Exhibits 1, 6) Species of wildlife likely to utilize the site include prothonotary warbler, parula warbler, Carolina wren, great crested flycatcher, tufted titmouse, pileated woodpecker, barred owl, marsh rabbit, raccoon, gray squirrel, flying squirrel and various small mammals, reptiles and amphibians. Mosquito fish were observed in the area of the project site during the September 1979 visit to the property by Respondent's permitting supervisor. (Testimony of Scott, Cox, Respondent's Exhibit 6)

Findings Of Fact The proposed project is a six-lane, combination low and high level bridge crossing Mill Cove and the St. John's River in Duval County, Florida. The project entails construction of approximately 6,000 feet of low level trestle-type bridge structure and approach spans beginning on the south side of Mill Cove and extending across the Cove to the northern edge of Quarantine Island, an artificial spoil island; 3,000 feet of high level bridge crossing the main channel of the St. John's River; and northern approach spans touching down on Dame Point on the northern shore of the St. John's River. In order to construct the proposed project, JTA is required to obtain a water quality permit and certification from DER. JTA filed its application with DER, accompanied by supporting data, including several studies performed by professional consultants. After review of the application, DHR filed notice of its intent to issue the requested water quality permit and certification, and Petitioners filed a timely request for a hearing pursuant to Section 120.57(1) Florida Statutes, to oppose the issuance of the permit and certification. Petitioners are various groups and individuals concerned about water quality in the St. John's River and the Jacksonville area. Petitioners' standing to seek relief in this proceeding was stipulated by all parties. Construction of the project will result in: filling of approximately .07 acres of wetlands to construct the south abutment on the shore of Mill Cove; dredging of approximately 185,000 cubic yards of material from Mill Cove to create a 4,400 foot long, 190 foot wide barge access channel, with a five foot navigation control depth parallel to the low level portion of the project; temporary filling of approximately .3 acres of wetlands above mean high water on the south shore of Quarantine Island to provide construction access to the island, which area is to be restored upon completion of construction; construction of a diked upland spoil containment site approximately 31 acres in size above mean high water on Quarantine Island to retain all dredge spoil associated with the project; construction of a temporary dock at the northern end of Quarantine Island for access and staging purposes, which is to be removed on project completion; and filling of approximately 16,000 cubic feet of material waterward of mean high water for rip-rap protection around main piers in the St. John's River. Dredged materials will be removed by hydraulic dredges. The St. John's River and its tributaries have been designated Class III waters by DER in the project area. The project involves dredging below mean high water and filling above mean high water, and is a dredge-and-fill project for purposes of Chapters 403 and 253, Florida Statutes, and Chapters 17-3 and 17-4, Florida Administrative Code, and is regulated by DER. The project is an element in a proposed eastern bypass around the City of Jacksonville. It is expected that, as a result of the project, existing area industry will receive more efficient transportation service, commuter trip miles from southeastern Jacksonville to northern Jacksonville will be reduced, transportation routes to education facilities will be improved, and tourist traffic will be routed around downtown Jacksonville, reducing miles traveled to nearby beach resorts and thereby relieving downtown congestion. The benefits to costs ratio of the project appears positive and beneficial to Duval County and Jacksonville, in that for every dollar spent to construct the project, $2.80 could be returned to the community in the form of increased economic activity and more efficient transportation. Testimony clearly established that the state waters in the project area are currently severely degraded and are not likely to meet Class III water quality standards. Violations of Class III standards for dissolved oxygen and some heavy metals, such as mercury, presently exist as background conditions in the St. John's River and Mill Cove. Further, a water quality analysis performed by DER in the project area indicates high background concentrations of heavy metals and PCB's in both the water column and sediments in the project area. When the pro posed project is analyzed within the context of these existing background water quality conditions, it appears highly unlikely that any impact from the project will further degrade existing conditions. The project as currently designed includes plans for total containment of spoil material resulting from dredging activity on the upland portions of Quarantine Island. There will be no direct discharge of dredge $materials from this containment area into the receiving waters of the state. JTA performed a water and sediment analysis of the project area, the purpose of which was to determine the existence and concentrations of specific pollutants that could adversely impact Class III waters if reintroduced into the aquatic system. JTA employed a consultant whose analytical program was designed in consultation with DER and complied with all standard testing procedures required by Rule 17-3.03, Florida Administrative Code. This analysis identified three primary-project activities where control of toxic and deleterious materials was critical: turbidity control; upland spoil containment; and direct discharge of spoil water to state waters. Sediments in the Mill Cove area are extremely fine and may be resuspended in the water column in quantities that could violate state water quality standards if dredging is done improperly. It appears from the evidence that any turbidity problem can be avoided by employing silt curtains and hydraulic dredging during channel excavation. Silt curtains should adequately retain turbidity below levels which would violate state water quality standards, in view of the fact that the JTA study hypothesized a "worst-case" condition for projecting turbidity and pollutant concentration by assuming no upland spoil containment, silt curtains or reasonable mixing zone. Although use of silt curtains and hydraulic dredging cannot absolutely guarantee zero-discharge of suspended sediments from the dredging area, the proposed system of turbidity control is adequate to provide reasonable assurance of non-violation of state water quality standards. Due to the existing toxic background conditions in Mill Cove, DER imposed a permit condition requiring spoil from dredging activities to be completely contained in an upland landfill-type site, with no overflow that could allow effluent to return to waters of the state. The upland dike system proposed in the project application is designed to retain all spoil material and water without direct discharge into state waters. Testimony established that the proposed dike system is designed to hold far more spoil material than the proposed project will generate. Although the dike system is to be constructed from dredged material previously deposited on Quarantine Island, it appears from the testimony that these materials were dredged from the main channel of the St. John's River and are cleaner and sandier in character than sediments in the Mill Cove area. The dike system, in conjunction with natural percolation and evaporation, is adequately designed to retain dredge spoil on the upland portion of Quarantine Island, and can reasonably be expected not to release toxic and deleterious substances into receiving waters of the state. It is also significant that a condition of the requested permit requires project water quality monitoring to afford continuing assurance that the project will not violate standards contained in Chapter 17-3, Florida Administrative Code. These standards and the conditions required to achieve them have been included in DER's letter of intent to issue the permit for this project. It is specifically concluded from the evidence that project dredging will not release toxic and deleterious substances into Class III waters in violation of state water quality standards, and that project dredging in Mill Cove incorporates reasonable safeguards for spoil disposal and turbidity control so as to assure non-violation of state water quality standards. JTA plans to use a direct discharge method to dispose of storm water from the bridge. Storm water will fall through 4-inch screened holes called "scuppers" placed at regular intervals along the bridge surface directly into either Mill Cove or the St. John's River. JTA was required to provide in its application reasonable assurance that storm water runoff from the Project would not exceed applicable state standards for turbidity, BOD, dissolved solids, zinc, polychlorinated biphenols, lead1 iron, oils or grease, mercury, cadmium and coliform. To this end, JTA submitted a study entitled Effect of Rainfall Runoff from Proposed Dame Point Bridge on Water Quality of St. John's River. This study analyzed the chemical composition of storm water runoff from an existing bridge, comparable in both size and design, to the proposed project, which crosses the St. John's River south of the City of Jacksonville. This study adequately established that storm water runoff into the St. John's River across the length of the proposed bridge will not degrade the water quality of the St. John's River below current water quality standards. All but three of the parameters tested in the study were within standards contained in Chapter 17-3, Florida Administrative Code. The remaining three pollutants were either not automobile-related, or would not violate applicable water quality standards after a reasonable opportunity" for mixing with receiving waters. One of these pollutants, mercury, is not automobile-related, and the concentration of mercury discovered in bridge runoff test samples was essentially the same as that measured in rainfall samples. The sampling for mercury was performed using the ultrasensitive "atomic absorption" method, which is capable of measuring tenths of a part per billion of mercury. Another method, the "Dithizone" method, is a technique recognized as effective by DER, and would have, if utilized, yielded a result within the "none detectable" standard contained in Rule 17-3.05(2) , Florida Administrative Code. As to the remaining two pollutants, coliform and lead, testimony established that a dilution rate of 400 to 1, after mixing with receiving waters, would not result in violation of applicable Class III water standards. Testimony also clearly established that water circulation in the project area would result in the requisite dilution ratio of approximately 400 to 1. The storm water runoff study was performed on a bridge similar in all important characteristics to the proposed project, and therefore validates the scientific methodology utilized to determine the expected impact of runoff from the proposed project on water quality in the St. John's River. The applicant has provided in its permit application the best practicable treatment available to protect state waters in the design of both the low and high level portions of the proposed bridge. Extensive research and analysis of design alternatives for both the low and high level portions of the bridge were undertaken by JTA and its consultants prior to selecting the proposed design for the bridge. JTA prepared and submitted to DER, as part of the application process, a document entitled Summary of Construction Techniques in Mill Cove, Dame Point Expressway. This document analyzed and summarized the available construction and design alternatives for the low level trestle portions of the project. The analysis included consideration of overhead construction, construction from a temporary wooden structure parallel to the project, and construction from barges using a shallow channel parallel to the project. The design chosen will cost more than one million dollars less than the next alternative, and will cut construction time by two years over the next alternative design. Given the demonstrated need for the proposed project, the already degraded water quality in the project area, the safeguards for water quality contained-in the project design, and the savings to be realized in both cost and time of construction, the design presently contained in the application is the best practicable. Both Petitioners and JTA have submitted proposed findings of fact. Petitioners' Proposed Findings of Fact numbered 1 through 4 have been substantially adopted herein. JTA's Proposed Findings of Fact numbered 1 through 7 have also been substantially adopted. To the extent that proposed findings of fact submitted by either Petitioners or JTA are not adopted in the Recommended Order, they have been specifically rejected as being either irrelevant to the issues in this cause, or as not having been supported by the evidence.
The Issue The issue to be determined in this case is whether the Respondents, Florida Department of Transportation (“FDOT”) and Palm Beach County (also referred to as “the Applicants”), are entitled to the issuance of an Environmental Resource Permit (“ERP”) to construct an extension of State Road 7 (“SR 7”) and its associated surface water management system in Palm Beach County.
Findings Of Fact The Parties The City is a municipality incorporated under Florida law. The District is a regional agency with the authority to regulate the construction, operation, and maintenance of any surface water management system pursuant to chapter 373, Part IV, Florida Statutes, and Florida Administrative Code Titles 40E and 62. FDOT is an agency of the state of Florida charged with the establishment, maintenance, and regulation of public transportation. It is a co-applicant for the ERP permit. Palm Beach County is a political subdivision of the State of Florida, and is a co-applicant for the ERP permit. Background State Road 7 Extension The ERP was issued by the District for an 8.5-mile extension of SR 7 between Okeechobee Boulevard and Northlake Boulevard in Palm Beach County. The purpose of the proposed roadway is to relieve traffic now moving through rural residential areas and two large residential developments known as The Acreage and Jupiter Farms. The proposed roadway would also improve hurricane evacuation by providing additional capacity and connectivity, and reduce emergency response time in the rural residential areas. The proposed roadway alignment was selected by FDOT after a multiyear corridor study under a National Environmental Protection Policy Act process. Four corridors were considered using federal selection criteria that addressed social, environmental, property, physical, and financial impacts. There are two segments of the proposed roadway covered by the ERP. The southern segment would add two more lanes to the existing two-lanes of SR 7 from Okeechobee Boulevard North to 60th Street North, just south of the M-Canal. This segment is 4.4 miles long. The southern segment is not at issue in this case. The northern segment would extend four lanes of SR 7 east from 60th Street North about one mile, and then north 3.1 miles to Northlake Boulevard. This is the roadway segment challenged by Petitioner. Hereafter, all references to “the Project” are to the northern segment. The Project includes a raised roadway, median, sidewalks, bike lanes, and stormwater swales. It also includes a bridge over the M-Canal and a bridge over a water control outfall. The Project would be constructed in an existing right- of-way (“ROW”). FDOT owns a ROW that is approximately 200 feet wide. The County owns an adjacent 120-foot-wide ROW, so that the total width of the Project ROW is 320 feet. Running north/south within the ROW is a dirt service road, a ditch, and a fence. Much of the vegetation in the ROW is dominated by invasive and exotic plant species, including Melaleuca, Carolina Willow, Brazilian Pepper, and Australian Pine. The Ibis Development West of the Project ROW is the 1,958-acre Ibis Golf and Country Club residential development (“Ibis”). In 1989, an ERP was issued for Ibis’ surface water management system (“the Ibis system”). The Ibis system includes almost 300 acres of interconnected lakes that provide water management and water quality treatment for Ibis. The 1989 permit required the Ibis system to be sized to receive and treat runoff from a segment of Northlake Boulevard and from an existing two-lane road off of Northlake Boulevard that serves the commercial area of Ibis, which is directly north of the Ibis residential area. The Ibis system was also required to receive and provide water treatment and storage for the stormwater runoff from 46.8 acres of the ROW for SR 7. The parties introduced evidence about modifications to the 1989 permit, which the City contends reduced the treatment capabilities of the system. It is found from the preponderance of the evidence that the original system and its modifications continued to meet design requirements to store and treat future runoff from 46.8 acres of the SR 7 ROW.1/ When the water in the Ibis lakes reaches elevation 17.5 feet NGVD (National Geodetic Vertical Datum), pumps at two pump stations at the south end of Ibis begin pumping water over a berm into Ibis Preserve, a 366-acre natural area directly south of Ibis. Water is retained in Ibis Preserve unles it exceeds an elevation of 18.5 feet, when it then passes over an outfall structure into the Grassy Waters Everglades Preserve (“Grassy Waters”) to the east. Ibis Preserve provides additional water quality treatment for the water pumped from Ibis, but this additional treatment was not part of the calculation of water quality management for Ibis. The Ibis system was required to meet District permitting criteria before discharge to Ibis Preserve. The North Palm Beach County Improvement District (“Improvement District”) owns and has operational and maintenance responsibility for the Ibis system. It also owned and managed Ibis Preserve, but transferred ownership and management of Ibis Preserve to the City in 2004. Grassy Waters/Water Catchment Area To the east of the Project is the City-owned “Water Catchment Area,” which covers about 14,700 acres or 23 square miles. The Water Catchment Area is owned by the City and is part of its public drinking water supply system. Water in the Water Catchment Area flows to Lake Mangonia where it is withdrawn, treated, and then delivered to residents and businesses in the City, the Town of Palm Beach, and the Town of South Palm Beach. There is a statement in the Project application that Grassy Waters refers only to the open water marsh within the Water Catchment Area. The Water Catchment Area includes other habitat types besides open marsh. Most of the information in the record indicates that Grassy Waters and the Water Catchment Area have the same boundaries. Therefore, in this Recommended Order, Grassy Waters and the Water Catchment Area are treated as being two names for the same area. Grassy Waters was once connected to the Everglades and large portions of it have the same characteristics, being an open water marsh with an extended hydroperiod. It is oligotrophic, meaning it is low in nutrients and has an ecosystem adapted to low nutrient conditions. It was undisputed that most areas of Grassy Waters are of high or even pristine environmental quality. Grassy Waters has periphyton, an assemblage of algae that only survive in phosphorous levels of less than 10 parts per billion (“ppb”). Periphyton is the base of the food chain in the open water marsh area of Grassy Waters and is consumed by apple snails and many invertebrates and fish. Grassy Waters has a visitor and nature center and provides recreational opportunities, such as canoeing, hiking, and bird watching. There appeared to be disagreement about whether the Project ROW is located in Grassy Waters or adjacent to it. The ROW is not within Grassy Waters, it is adjacent. However, the wetlands and other surface waters within the ROW are hydrologically connected to Grassy Waters. In the western part of Grassy Waters, which ends at the Project ROW, there are hammock islands and hydric pine flatwoods. The City contends these areas and the rest of the ROW were historically open water marsh, but were changed by human activities. The more persuasive evidence is that this western area was not all open marsh, historically. It was an area of natural transition from open water marsh to other habitat types. Ibis Impacts to Grassy Waters The parties disputed whether the Ibis system is a “failed system.” This is not a technical or defined term. The relevant issue is whether the Ibis system is operating in conformance with the requirements of its permit. The City contends the Ibis lakes are eutrophic and that sediment accumulation in the lakes is releasing phosphorus back into the water, which ends up in Grassy Waters. However, the City’s expert witness, Dr. Harper, admitted that the phosphorus concentration being discharged from the Ibis system, about 40 ppb, is typical for surface water management systems serving large residential developments, although that concentration is at the high end of the range. The phosphorus concentration is closer to 30 ppb in discharges from Ibis Preserve into Grassy Waters, showing that Ibis Preserve provides additional treatment to the waters coming out of Ibis. The characterization of the nutrient loading from the Ibis system as “typical” did not address the additional nutrients in the drainage that the Ibis system is required to accept from the SR 7 ROW. The record does not show that the nutrient concentrations from the Ibis system would still be typical if all of the ROW drainage were added without pre-treatment, as was contemplated by the 1989 Ibis permit. Because Grassy Waters is an oligotrophic ecosystem, it can be adversely affected by phosphorus levels above 10 ppb. When phosphorus is introduced into an oligotrophic system in concentrations over 10 ppb, the system begins to change to denser wetland vegetation, which can include invasive and nuisance species, such as cattail. There is denser vegetation and cattails in Grassy Waters near the Ibis Preserve outfall. There is also more phosphorus in sediments near the outfall. These effects decrease with distance from the outfall, but some effects were detected as far as a half mile from the outfall. The City’s expert witness, Dr. Gaiser, testified that periphyton is dissolved by high nutrient levels and replaced by weedy algae. She found adverse effects on periphyton near the outfall. Dr. Gaiser also found microcystis near the outfall. Microcystis is a toxic algae caused by high elevations of phosphorous. Microcystis comprised over 10 percent of the cell density of the algal community near the outfall. The District’s witness, Mr. Waterhouse, conceded that there is a problem with nuisance vegetation at the discharge point into Grassy Waters. He said the District was not aware of the problem before information was developed for this case. No evidence was presented about what consideration the District gave in 1989, when Ibis was permitted, to the potential adverse impacts of discharging phosphorus into the oligotrophic ecosystem of Grassy Waters. Based on the evidence that a phosphorus concentration of 30 ppb is expected for this kind of surface water management system, it must be concluded that the Ibis system was not designed to prevent harm to oligotrophic receiving waters. Respondents presented evidence to show that phosphorus loadings from the M-Canal could be the cause of the adverse impacts found near the Ibis Preserve outfall. The M-Canal was constructed by the City for the primary purpose of delivering water from Lake Okeechobee, via connection to the L-8 Canal, to the Water Catchment Area for public water supply. For most of its length, the M-Canal runs through Grassy Waters. The City generally maintains the water level in the M-Canal below the elevation of Grassy Waters so water in the canal will not flow into Grassy Waters. However, on some occasions, water flows from the M-Canal into Grassy Waters. High phosphorus concentrations have been recorded in the M-Canal; as high as 300 ppb. Nuisance vegetation is growing in the area where the M-Canal connects to the Water Catchment Area. The preponderance of the evidence establishes that the adverse impacts described by the City’s experts in the area of the Ibis Preserve outfall are caused primarily by discharges from Ibis Preserve. There are three other developments adjacent to Grassy Waters that occasionally discharge to Grassy Waters. These discharges are likely to contain some nutrients, but the amount of nutrients and their effects, if any, on Grassy Waters were not described in the record. The Water Catchment Area is a Class I waterbody because it is used for public water supply. The water quality standard for phosphorus and other nutrients in a Class I waterbody is set forth in Florida Administrative Code Rule 62-302.530(48)(b): In no case shall nutrient concentrations of a body of water be altered so as to cause an imbalance in natural populations of aquatic flora or fauna. Grassy Waters was designated by the Department of Environmental Protection (“DEP”) as a stream. Rule 62-302.531(2)(c) states that the narrative criterion “shall be interpreted as being achieved in a stream segment where information on chlorophyll a levels, algal mats or blooms, nuisance macrophyte growth, and changes in algal species composition indicates there are no imbalances in flora or fauna.” The City presented some evidence regarding nuisance macrophyte growth and changes in algal species composition in Grassy Waters near the Ibis Preserve outfall. Little evidence was presented regarding the practice of DEP or the District in the application of the narrative nutrient standard, but the preponderance of the evidence indicates the agency practice is to consider a stream segment as a whole to determine whether it exhibits an imbalance in natural populations of aquatic flora and fauna.2/ During the course of this proceeding, the District issued administrative complaints against the Improvement District and the City, which include Orders for Corrective Action. The complaints were issued pursuant to section 373.119, Florida Statutes, which authorizes such action when a water management district believes that a violation of any provision of chapter 373 or district rule has occurred. However, at the final hearing, the District was reluctant to say the Improvement District had violated any law or permit condition. The Improvement District did not challenge the enforcement action against it and, therefore, the District’s enforcement order became final. The Improvement District is required to address the accumulation of sediment in the Ibis Lakes, develop a nutrient source control plan, eliminate and reduce the use of herbicides containing copper sulfate, and reassess pumping schedules. There is no target nutrient limit specified in the District’s Orders for Corrective Action. The District’s enforcement action against the City seeks to require the City to increase secondary treatment and retention in Ibis Preserve, provide a plan to remove the exotic/invasive vegetation at the outfall, provide a vegetation monitoring plan, and develop source control measures for residential developments that discharge into Grassy Waters. The City challenged the enforcement action and it remains pending. Snail Kites The Everglades snail kite gets its name from its primary food, the apple snail. In the Everglades, snail kites also feed on an exotic island snail, which occurs there in about equal numbers as apple snails. There was no evidence presented that there are exotic island snails in Grassy Waters. Snail kite habitat is dependent on conditions conducive to apple snails, which are the open marsh and oligotrophic conditions where periphyton flourish. If a sufficient number of apple snails are present, snail kites will find suitable nesting nearby. Dense wetland vegetation is not good forage for snail kites because, even if apple snails are present, the apple snails will be difficult or impossible for the snail kites to see. Dr. Welch, who was the state snail kite conservation coordinator at the Florida Fish and Wildlife Conservation Commission and wrote the snail kite management plan for Florida, testified for the District, where he is now employed as a senior scientist. He said field surveys of snail kite nests in Grassy Waters indicate their numbers are relatively low compared to other areas where snail kites are found. There were only ten successful nests (eggs laid) observed from 2000 to 2016. The City’s Everglades expert, Dr. Lodge, speculated that the low nest counts could be due to difficulty in seeing the nests, but he was not familiar with the survey techniques used and, therefore, his opinion that the numbers could be materially underestimated is not credited. Snail kites nest throughout the Water Catchment Area, but primarily in the open marsh areas of the central and eastern portions of the Water Catchment Area. Over 90 percent of snail kite nests are more than a mile from the Project ROW. Dr. Lodge said there are four snail kite nests within 800 feet of the Project, but he was not more specific about their locations. Most nests are closer to Northlake Boulevard, State Road 710, and the Florida Turnpike. The major factor that adversely affects successful nesting by snail kites and production of offspring is predation, usually by raccoons and rat snakes. “Cold snaps” and drought are also factors. Impacts of The Proposed Project Water Quantity Impacts Water storage for the Project, which was going to be handled in the Ibis system under the 1989 Ibis permit, would be provided in the roadside swales. The Project is designed to retain water volumes greater than typically required for roadways. Stormwater would not flow out of the Project into the Ibis system except in unusually large storm events, in excess of six inches of rainfall. The City did not dispute the Project’s compliance with the applicable water quantity criteria in the District rules. Water Quality Impacts To address the City’s concerns about adverse impacts caused by the Ibis system, the Applicants expanded the roadside swales by ten feet and raised the outfall elevation by 0.05 feet. With these modifications, the Project would provide water quality treatment for its stormwater and no longer rely on the Ibis system for treatment. The swales would provide treatment in excess of the treatment required by District rules. Respondents contend that, when the treatment provided by the Ibis system is added, the total treatment provided for the Project stormwater is more than twice as much as required by District rules. The City, on the other hand, claims that no additional water quality treatment can be provided by the Ibis system because the Ibis Lakes are eutrophic. The preponderance of the evidence supports a finding that Project runoff to the Ibis system would receive additional water quality treatment in the Ibis system and in Ibis Preserve before flowing to Grassy Waters. The effect of the Project’s on-site treatment of its stormwater is that the amount of nutrients that would otherwise flow into the Ibis system from SR 7 would be reduced. Therefore, the effect of the Project is to reduce the nutrient load that the Improvement District was permitted to discharge to Ibis Preserve and Grassy Waters. The City did not dispute the Applicants’ evidence that the Project exceeds the District’s design criteria for water quality. The City focused instead on its contention that, despite its compliance with water quality design criteria, the Project would result in additional nutrient loading to Grassy Waters, which would cause additional adverse impacts to its flora and fauna. The Applicants and the City performed nutrient loading analyses even though such analyses are only required by the District when the receiving waters have been designated by the Department as “impaired” by nutrients or in the case of certain other specially designated waters. Grassy Waters does not have any of these special designations. The Applicants’ nutrient loading analysis concluded that the post-development loading of phosphorus and nitrogen from the Ibis system would be less than the pre-development condition, so there would be a net decrease in nutrients discharged into Grassy Waters. Petitioner’s expert witness, Dr. Harper, believes the Project would increase nutrient loading to Grassy Waters, even if stormwater from the Project did not carry additional nutrients, because the increased volume of water moving through the Ibis system would entrain more nutrients from sediments in the Ibis lakes. Dr. Harper believes the Project would also cause nutrient loading via groundwater seepage through the roadway swales into Grassy Waters. The preponderance of the evidence does not support his opinion that groundwater seepage would cause additional nutrient loading.3/ Dr. Harper believes another source of nutrient loading from the Project would be from surface flow down the roadway embankments. On the eastern embankment, this flow would enter the mitigation area 150 feet from Grassy Waters. Dr. Harper’s estimated total loading from all sources is not persuasive. The estimate gives a false sense of precision. It is based on a number of variable assumptions, some of which are not widely known or in use by experts in the field. In addition, Dr. Harper’s opinion did not appear to appropriately account for the modifications to the Project’s storage capacity. Dr. Harper’s estimated loading was not translated into physical effects in Grassy Waters. The Applicants’ estimate of total nutrient loading also gives a false sense of precision, but it is based on a well-known and widely used methodology. The City failed to prove that the Project would result in more nutrient loading to Grassy Waters than is currently contributed by the ROW. Because the Project would not rely on the Ibis system for stormwater treatment, the Project would reduce the loading that the Improvement District was permitted to discharge to Grassy Waters. To address potential vehicular spills into Grassy Waters, FDOT produced a Spill Response Plan. The swales would capture and contain any material spilled on the roadway or swale. The curb and gutter, a guardrail, gravity wall, and fence also provide protection against spills. The bridge over the M-Canal would use a 54-inch traffic barrier, which is higher than FDOT specifications for the design speed for the bridge. The City did not present evidence to show that the protective measures proposed by the Applicants are less than what is usually considered adequate under similar circumstances, or fails to meet a relevant safety standard. Wetland Impacts Direct Impacts The Project would directly impact 52.37 acres of wetlands and 7.86 acres of surface waters. The impacted wetlands are fresh water marsh, mixed shrubs, and hydric pine flatwoods. The surface waters affected consist of vegetated ditches and un- vegetated channels or canals. The impacted wetlands include 11.77 acres of freshwater marsh. The impacted surface waters are ditches. Most of these wetlands are disturbed and their functional values have been reduced. Secondary Impacts District rules require an applicant to account for the secondary impacts caused by a project that could adversely affect the functions of adjacent wetlands or other surface waters. The Applicant’s Handbook defines secondary impacts to include impacts on wetland functions, water quality, and endangered species, including impacts on areas needed by endangered species for foraging. Part of the Applicants’ assessment of secondary impacts of the Project was made by reviewing the effects of the Acreage Reliever Road on Pond Cypress Preserve, a 1,737-acre conservation area managed by the County that is immediately south of the proposed Project. The County has been monitoring the effect of the Acreage Reliever Road on hydrology, vegetation, and species compensation ever since the road was built. The County found no adverse secondary impacts caused by the road. The species that use the wetlands near the road, including wading birds, appear to be unaffected by the road. The scoring of secondary impacts for the Projects, using the Uniform Mitigation Assessment Methodology (“UMAM”), was conservative, meaning that assumptions were made at the high side of the potential range of impacts. This resulted in more mitigation being required. The Applicants claim the Project would “maintain a 300-foot buffer between the project’s construction boundary and [Grassy Waters].” This appears to be a misstatement. The Applicants’ combined ROW is only 320 feet wide. Going east from the limits of construction, it is 160 feet to Grassy Waters. The Project’s buffer is 160 feet wide. The District accounted for secondary impacts to wetland dependent species, including snail kites, from noise and lights that might discourage use of the area. The Project would provide a tree buffer that will reduce noise and light impacts to Grassy Waters. The roadway lighting plan is also intended to reduce light penetration into Grassy Waters. Most of the threatened and endangered bird species are tolerant of roadways for foraging and roosting, but not for nesting. Section 10.2.7 requires the Applicants to provide reasonable assurances that any future phase of a project or project-related activities will not result in adverse impacts to the functions of wetlands or water quality violations. The Applicants satisfied this requirement by releasing of FDOT ROW north and south of the Project. Cumulative Impacts An applicant must provide reasonable assurance that a regulated activity will not cause unacceptable cumulative impacts upon wetlands and other surface waters within the same drainage basin as the regulated activity for which a permit is sought. Some of the proposed mitigation for the Project is out- of-basin. If an applicant proposes to mitigate impacts in another drainage basin, District rules require consideration of factors such as “connectivity of waters, hydrology, habitat range of affected species, and water quality” to determine whether there are unacceptable cumulative impacts. The Project is located in the eastern Palm Beach County Basin, which has approximately 21,000 acres of wetlands. About 89 percent of the wetlands in the basin are publicly-owned conservation lands, which means their wetland functions will continue into the future. The cumulative impact analysis was conservative, meaning that the actual impacts are likely to be fewer. Petitioner contends that Respondents’ cumulative impact analysis did not account for the unique nature of the Grassy Waters ecosystem as the only remaining low nutrient oligotrophic wetland in the region. The preponderance of the evidence shows that the historical wetland types in the Project area were not all like the open marsh found in the central and eastern portion of Grassy Waters. Respondents accounted for the loss of open water marsh that would be caused by the Project. On-Site Mitigation There would be 52.4 acres of on-site mitigation within a 160-foot-wide strip of land along the eastern limits of proposed construction. This area of the ROW would be managed by removing or treating the exotic vegetation, such as Brazilian Pepper and Maleleuca. Removing the exotic vegetation seed source would prevent further spread of these nuisance species into Grassy Waters. Where native habitats have been altered with ditches and berms, the land would be graded to create a slope from the limits of construction eastward to the edge of the ROW. The eastern elevation would be similar to the adjacent marsh or hydric pine areas of Grassy Waters. Then, native vegetation would be planted. The habitats enhanced, restored, or created would include freshwater marsh, hydric pine flatwoods and mixed forested wetlands, including cypress. The planting of mixed, forested species would provide sound and light buffering for snail kites and other species in Grassy Waters. Two wildlife passages would be created underneath the Project with fencing designed to direct wildlife to use the wildlife passages. Slats would be placed in the roadway fencing to prevent small animals from going through the fence and onto the roadway. The on-site mitigation was scored using UMAM and determined to result in functional gain. The UMAM analysis was conservative, meaning that the actual functional gain is likely to be greater. The City did not contest the UMAM scoring. Off-site Mitigation FDOT is applying mitigation credits from 210 acres at the Pine Glades Natural Area (“Pine Glades”) to offset impacts to 15.7 acres of herbaceous marsh and 26.78 acres of forested wetland impacts. Pine Glades is a regional off-site mitigation area located in the Loxahatchee River Basin and is owned and operated by Palm Beach County. Pine Glades consists of a mix of wet prairie, depression marshes, hydric pine flatwoods, and mesic flatwoods. The restoration work in Pine Glades has already been completed. Pines Glades implements a detailed management plan that provides regional ecological value. Robbins testified that Pine Glades has similar habitats to Grassy Waters. Pine Glades has periphyton, apple snails, snail kites, wood storks, and sand hill cranes. Pine Glades has some areas with oligotrophic conditions. Additional off-site mitigation to offset 52 acres of wetland impacts caused by the Project would be provided at the DuPuis Reserve (“DuPuis”). DuPuis is a regional off-site mitigation area located between the L-8 Canal and the C-44 Canal in western Palm Beach and Martin Counties, and is owned and operated by the District. DuPuis would provide mitigation with 34.71 acres of herbaceous wetlands and 43.8 acres of forested wetlands. DuPuis is appropriate to offset the impacts associated with the Project because it provides similar habitats with similar values of functions for similar wildlife. DuPuis implements a detailed management plan that provides regional ecological value. The City argues that there is little similarity between the Grassy Waters ecosystem and Pine Glades or DuPuis, so the mitigation there cannot offset the unique assemblage of plants and animals that would be lost in Grassy Waters. It is unnecessary for Pine Glades and DuPuis to be dominated by open water marshes like Grassy Waters. It is only necessary that they have some of these areas to offset Project impacts to open water marsh. Proposed snail kite mitigation would provide 52.5 more acres of snail kite habitat than would be directly impacted by the Project. The mitigation for snail kites will be located in FDOT ROW adjacent to the Project, south of the M-Canal, and north of Northlake Blvd. Erwin expressed concern about fragmentation of the ecosystems that would be caused by the Project. The areas that would be affected by the Project have already been fragmented by berms, ditches, and fences. Grassy Waters is surrounded by berms, a canal, and highways. The Project would cause fragmentation, like all roads. However, the fragmentation was reduced where practicable, and the City did not show that the roadway would cause the loss of any significant “greenway” now used by wildlife. Snail Kite Impacts Section 10.2.2(a) requires an applicant to provide reasonable assurances that a proposed activity would not impact wetlands and other surface waters so as to reduce the abundance and diversity of listed species. Snail kites, wood storks, sandhill cranes, white ibises, and little blue herons are listed species that have been observed within the Project corridor. As explained in the Conclusions of Law, the UMAM process is designed to mitigate for wetland functional losses, not snail kite functional losses. However, the potential impact to any listed species warrants close attention to the issue of whether function-for-function wetland mitigation would be provided. There will be 11.5 acres of direct impacts to snail kite habitat within the footprint of the Project area. Dr. Welch believes secondary impacts to wetland functions associated with snail kites could extend 800 feet east of the ROW. Mitigation for snail kites would be located in the Rangeline corridor south of the M-Canal and north of Northlake Boulevard. Dr. Welch estimated there were about 64 acres of snail kite habitat in the Rangeline corridor similar to the 11.5 acres of habitat located in the Project footprint. Dr. Welch conceded that he has no evidence that snail kites currently use the Rangeline, but he believes the habitat is suitable and is appropriate mitigation. Petitioner claims there are studies of “similar birds” indicating that snail kites avoid highways due to noise. However, the studies were not of similar birds. More weight is given to Dr. Welch’s testimony that snail kites are not particularly sensitive to roadway noise. Dr. Welch stated that Pine Glades would likely have value for snail kites because it is near the Hungryland Wildlife Management Area, which has the same number of successful snail kite nests as Grassy Waters. The City contends that Pine Glades is too far away from Grassy Waters to mitigate Project impacts to snail kites. However, snail kites range long distances to forage; several hundred miles in a few days. Satellite telemetry of snail kites shows snail kites from Grassy Waters are using Pine Glades for feeding. Dr. Welch reviewed snail kite nesting data to determine whether roads deterred nesting and found that snail kites frequently nested within 500 feet of major roadways. Dr. Welch refuted the idea that Grassy Waters provided snail kite refuge during drought conditions, because Grassy Waters is also subject to drought conditions that adversely affect snail kites. There are conditions in the permit to limit potential impacts to snail kites during construction of the Project. If snail kite nesting is observed within 1,640 feet of construction, all Project construction must cease. Thereafter, monitoring of the nest and notification of the U.S. Fish and Wildlife Service is required. Construction cannot resume until that nest has been considered finished. FDOT would place a conservation easement over 82.6 acres in the FDOT ROW between Okeechobee Boulevard and the M-Canal, south of the Project area that is the subject of this proceeding. The conservation easement would maintain connectivity between the Pond Cypress Natural Area and Grassy Waters and ensure that no future southern extension of the roadway will be constructed. A conservation easement would be placed on the FDOT ROW between Northlake Boulevard and SR 710, an area of approximately 43.5 acres. Preserving this area protects a hydrologic connection between Loxahatchee Slough Natural Area and Grassy Waters. It also ensures no future northern extension of the roadway. A conservation easement would be placed on a portion of the FDOT ROW between SR 710 and Jupiter Farms, an area of 44.5 acres. This section of ROW is in the Loxahatchee Slough and the release of the ROW would be a direct benefit to Loxahatchee Slough. The preservation of these areas would benefit fishing and recreational values in the Pond Cypress Natural Area, Grassy Waters, and the Loxahatchee Slough Natural Area. These conservation areas did not receive UMAM credits to reduce the wetland acreage needed to offset wetland functional losses, but they were included in the mitigation credit for benefits to snail kites and other wildlife. Summary The preponderance of the evidence established that the proposed mitigation offsets the impacts to wetlands and other surface waters that would be caused by the Project and exceeds the requirements of District rules. Practicable Design Modifications District rules require an applicant to consider alternatives that would avoid or reduce wetland impacts. The City claims the Applicants failed to comply with this rule because FDOT selected a roadway corridor that was expected to have greater environmental impacts than some of the other three corridors that were being considered. As explained in the Conclusions of Law, this argument is misplaced. The District’s review of the Applicants’ measures to avoid or minimize wetland impacts was appropriately confined to Corridor 3, the corridor selected by FDOT where the Project is proposed. The Applicants reduced and eliminated impacts of the Project in several ways. For example, the footprint of the road was narrowed from six lanes to four lanes, wildlife underpasses were provided, retaining walls were used to narrow stormwater features, the median was reduced in size, and the design speed limit was reduced for the bridge at the M-Canal crossing. Under two circumstances, District rules allow an applicant to avoid the requirement to implement practicable design modifications to reduce or eliminate wetland impacts, which are referred to as the “opt-out” provisions. Section 10.2.1.2, Volume I, of the Applicant’s Handbook (“A.H.”) provides: The ecological value of the functions provided by the area of wetland or other surface water to be adversely affected is low, based on a site specific analysis using the factors in section 10.2.2.3, below, and the proposed mitigation will provide greater long term ecological value than the area of wetland or other surface water to be adversely affected, or The applicant proposes mitigation that implements all or part of a plan that provides regional ecological value and that provides greater long term ecological value than the area of wetland or other surface water to be adversely affected. The District determined that the Applicants meet both tests. The preponderance of the evidence supports the District’s determination. The ecological value of the functions provided by the affected wetlands and surface is low and the proposed mitigation would provide greater long-term ecological value than the area being impacted. Pine Glades and DuPuis are part of a plan to restore the ecological value of Northern Palm Beach County and create an “ocean to lake” system of preserves and natural areas.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the South Florida Water Management District enter a final order approving Permit Number 50-05422-P on the terms and conditions set forth in the amended Staff Report, and the complete application for the Permit. DONE AND ENTERED this 31st day of March, 2017, in Tallahassee, Leon County, Florida. S BRAM D. E. CANTER Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 31st day of March, 2017.
The Issue The issues are whether Georgia-Pacific Corporation is entitled to the issuance of an industrial wastewater facility permit under the National Pollutant Discharge Elimination System program that would authorize it to discharge industrial wastewater to the St. Johns River in Putnam County, Florida, and whether Georgia-Pacific Corporation has met the statutory criteria for a related administrative order for the interim discharge to Rice Creek in Putnam County, Florida.
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: The Parties Respondent, Department of Environmental Protection (Department), is the state agency authorized under Chapter 403, Florida Statutes, to regulate discharges of wastes to waters of the State. Under approval from the United States Environmental Protection Agency (EPA), the Department administers the National Pollutant Discharge Elimination System (NPDES) permitting program in the State. The Department also enforces specific water quality standards that have to be achieved in order to ensure protection of the designated uses of surface waters in the State. Respondent, Georgia-Pacific Corporation (Georgia- Pacific), owns and operates a bleached and unbleached kraft pulp and paper mill in Putnam County, Florida. The plant presently discharges treated wastewater to Rice Creek, a Class III water of the State, and a tributary of the St. Johns River. Petitioner, Putnam County Environmental Council, Inc. (PCEC), alleged in the Petition for Formal Administrative Hearing (Petition) that it is a non-profit Florida corporation headquartered in Palatka, Florida. However, other than a statement by one witness that PCEC was incorporated on an undisclosed date prior to the hearing, PCEC failed to present any evidence to establish its corporate status or residency in the State of Florida. According to the same witness, the organization was created in an unincorporated status in 1991, and it currently has 65 members who use and enjoy the St. Johns River for recreational purposes. Petitioner, Stewards of the St. Johns River, Inc. (SSJR), also alleged in the Petition that it is a non-profit Florida corporation with headquarters in Jacksonville, Florida. Like PCEC, SSJR failed to prove its corporate status or residency in the State of Florida. Although the number of members in SSJR is unknown, "many" of its members are boaters and "most" live along the St. Johns River. Petitioner, Linda Young, is Southeast Regional Coordinator for the Clean Water Network and a citizen of the State of Florida. As such, she has standing to "intervene" in this action under Section 403.412(5), Florida Statutes. In this complex case, the parties have presented extensive and conflicting evidence regarding the factual issues raised by the pleadings. In resolving the numerous conflicts in that testimony, the undersigned has accepted the more credible and persuasive evidence, as set forth in the findings below. The Applicant's Mill Operation Georgia-Pacific's Palatka mill was built in the 1940's before the establishment of Department water quality standards and classifications. Because of the nature of the pulping process, the mill has not been able to fully meet water quality standards in Rice Creek because of poor dilution. Georgia-Pacific receives wood chips from a sister facility and purchases residual chips from local wood products facilities. Those chips are separated into pine and hardwood, conveyed into the pulp processing facility, and loaded into digesters, that is, industrial-sized pressure cookers, which cook the chips for several hours. Pulp from the digesters goes to the brown kraft, bleached kraft, and tissue manufacturing facilities. Water in the manufacturing process is used, re-used, and recirculated until it cannot be used again, at which point it is conveyed into a primary wastewater clarifier, which is used to settle out fiber and other settleable solids. Additional wastewater sources are collected in sumps located in the facility, which are discharged into the primary clarifier. The underflow from the primary clarifier flows into a solids settling area (sludge pond) while the water from the primary clarifier passes into a secondary treatment system. The secondary treatment system uses aerobic and facultative biological treatment. Stormwater at the facility also flows into the treatment system. The secondary treatment system consists of four ponds in series: Pond 1, 485 acres, aerated with over 1600 horsepower of aeration; Pond 2, 175 acres, with 140 horsepower of aeration; Pond 3, 130 acres, with 120 horsepower of aeration; and Pond 4, 100 acres. Pond 4 is a quiescent basin, used to settle solids in the wastewater before discharge. The treatment system has a very long hydraulic detention time; once water enters the system, it remains there for 50 to 60 days. After treatment, a side stream of roughly 8,000,000 gallons per day of treated effluent is withdrawn, oxygenated with liquid oxygen, and discharged at two locations in Rice Creek: 3.4 miles upstream from the St. Johns River (Outfall D-001); and 2.4 miles upstream from the St. Johns River (Outfall D-002). Under low flow conditions, effluent from the Georgia-Pacific mill dominates the flow in Rice Creek. The Application Process Rice Creek is a small tributary of the St. Johns River, particularly in its upper reaches where Georgia- Pacific's effluent discharge occurs. Over the years, there have been exceedances of certain Class III water quality standards including specific conductance, color, and periodically whole effluent toxicity. Because of this, and during the permit review process, the Department began considering alternatives for mitigating or eliminating those existing concerns with the facility's discharge. In October 1992, Georgia-Pacific applied to the Department for the renewal of its existing wastewater discharge permit. In June 1994, Georgia-Pacific submitted an application to the Department for the construction and operation of an industrial wastewater treatment and disposal system. This application included a request to relocate Georgia-Pacific’s existing discharge to the St. Johns River. Because Georgia-Pacific submitted timely permit applications, it is authorized to continue operations based on an "administratively extended permit." In June 1994, Georgia-Pacific also applied to the EPA for a permit under the NPDES program. In October 1994, the EPA acknowledged receipt of a timely application for the renewal of Georgia-Pacific's existing NPDES permit, advising Georgia-Pacific by letter that its permit was automatically extended and that continued operation was authorized in accordance with the existing permit and 5 U.S.C. Section 558(c). On May 24, 1995, the Department advised Georgia- Pacific that the EPA had granted the Department the authority to administer the NPDES program and that its state permit and existing NPDES permit were deemed combined into one order. In response to a Department request, in November 1995, Georgia-Pacific submitted to the Department an antidegradation review for the relocation of its discharge. After Georgia-Pacific applied to the Department for a renewal of its NPDES permit, the Department directed Georgia-Pacific to provide alternatives that would ensure compliance with water quality standards. Georgia-Pacific submitted a proposal to construct a pipeline that would enable it to discharge its effluent to the middle of the St. Johns River. Under that proposal, Georgia-Pacific would achieve compliance with water quality standards as a result of greater dilution in the St. Johns River. Based on a review of Georgia-Pacific's submittal, the Department determined that Georgia-Pacific could in fact achieve water quality standards by constructing a pipeline to the St. Johns River. Likewise, the EPA concluded that Georgia-Pacific could receive a permit to discharge to the St. Johns River through a pipeline, without additional process improvements. Although the Department concluded that compliance could be achieved solely by the construction of a pipeline, it began discussions with Georgia-Pacific and EPA in order to examine other approaches that might lead to compliance in Rice Creek. These discussions culminated in a decision that Georgia-Pacific would invest substantial funds in the installation of additional technology and also be assured of some ultimate means to achieve compliance with water quality standards. On May 1, 2001, the Department issued a Notice of Intent to Issue an industrial wastewater permit, together with an Order Establishing Compliance Schedules Under 403.088(2)(f), Florida Statutes (the Administrative Order). In late January 2002, Georgia-Pacific submitted a request to the Department asking for consideration of two changes to the proposed permit: first, a request to relocate a groundwater monitoring well; and second, a request to review the Department's proposed mixing zone in the St. Johns River for the transparency standard. The Department also proposes a minor change in permit conditions to allow approval of the bleach plant monitoring plan to take place within sixty days after the issuance of the final permit. Both of Georgia- Pacific's requests were reviewed by the Department, and it has recommended that they be included in the proposed permit. Technology-Based Effluent Limits and Water Quality- Based Effluent Limits When considering a permit application such as the one here, the Department reviews the application to determine compliance with technology-based effluent limits (TBELs) and water quality-based effluent limits (WQBELs). TBELs are minimum industry standards that all facilities must meet regardless of their discharge location. They are predominantly production-based, and they limit the mass of pollutants that may be discharged based on the mass of product produced. Those limits generally reflect EPA's assessment of the industry standard regarding what can be met in a given discharge. In the preparation of a permit, the Department practice is to first determine the TBELs that would apply. In contrast, a WQBEL reflects how low the discharge must be (or how effective treatment must be) for a given parameter to meet water quality standards. Relief mechanisms such as mixing zones are inherent in WQBELs. A WQBEL is necessary only for those parameters for which there is a reasonable potential for the facility either to exceed the water quality standard or come close to exceeding the standard. As a matter of agency practice, the Department does not impose a limit unless there is a reasonable potential to exceed a standard. In order to determine whether there is such a reasonable potential for exceeding a standard, the Department will review past operations and other information it may have regarding the characteristics of the discharge. For a discharge such as the one proposed in the present case, a "Level II" WQBEL is required. The Department's Point Source Section, with expertise in the field of water quality modeling, analyzes the Level II WQBEL. Georgia-Pacific must meet certain technology-based standards, such as those set forth in the Cluster Rule. The Cluster Rule has been promulgated by the EPA and adopted by the Department and requires the installation of technologies to eliminate the use of elemental chlorine in the bleaching process. The Palatka facility far exceeds (performs better than) technology-based effluent limits. In March 1998, the Department created a document titled "Level II Water Quality Based Effluent Limitations for the Georgia Pacific Corp. Palatka Mill" (the WQBEL Technical Report]. The WQBEL Technical Report has a typed notation on the title page reading "March 1998 -- Final." The WQBEL Technical Report contained the following effluent discharge limitations: The following are the effluent limitations for the Georgia-Pacific Palatka mill discharge to the St. Johns River based upon results from the Level II WQBEL. Review comments from EPA Region 4 are included in the correspondence section. Parameter Limitation Discharge 60 MGD Daily Maximum BOD5 Summer (June 1 - November 30) 3,500 lbs/day maximum thirty day average Winter (December 1 – May 31) 7,170 lbs/day maximum thirty day average TSS Summer (June 1 - November 30) 5,000 lbs/day maximum thirty day average Winter (December 1 – May 31) 10,000 lbs/day maximum thirty day average Dissolved Oxygen 2.7 mg/l minimum Specific conductance 3,220 umhos/cm daily maximum Un-Ionized Ammonia Nitrogen Summer (June 1 - November 30) .11 ug/l daily maximum Winter (December 1 – May 31) .13 ug/l daily maximum Iron (Total Recoverable) 2.91 mg/l daily maximum Cadmium (Total Recoverable) 3.46 ug/l daily maximum Lead (Total Recoverable) 5.87 ug/l daily maximum Zinc (Total Recoverable) 480 ug/l daily maximum When the WQBEL Technical Report was approved in 1998, the Department's Northeast District Office did not prepare a separate formal notice of approval. The WQBEL Technical Report was transmitted by memorandum from the Water Quality Assessment Section to the Department's Director of District Management for the Northeast District on April 13, 1998, where it remained on file. The WQBEL Technical Report complied with the plan of study previously approved by the Department, and it met the requirements of Rule 62-650.500, Florida Administrative Code. Both the Department and EPA staff concurred with the approval of the WQBEL Technical Report. They agreed that the construction of a pipeline and the relocation of the discharge to the St. Johns River would yield a net environmental benefit without additional process improvements. Upgrades Implemented and Required in the Proposed Agency Actions As described more fully below, Georgia-Pacific has modified its production and treatment processes in such a manner as to improve its overall environmental performance. In installing some of those modifications, Georgia-Pacific undertook what was required by federal and state law. For others, Georgia-Pacific has exceeded what it was required to do under state or federal law. To comply with the Cluster Rule, Georgia-Pacific eliminated two bleach plants and installed a new bleach plant, one which uses chlorine dioxide as opposed to elemental chlorine. The implementation of this technology is primarily aimed at eliminating the mechanism for the formation of dioxin in the bleaching plant. Compliance with the Cluster Rule generally requires, among other things, conversion to an elemental chlorine-free bleaching system. Georgia-Pacific is in compliance with the Cluster Rule. Under the Cluster Rule, Georgia-Pacific is required to sample for dioxin at its bleach plant, with a limit of under 10 picograms per liter. Georgia-Pacific has experienced reductions in the color of its effluent as the result of the chlorine dioxide conversion as well as reductions in specific conductance. The reductions in specific conductance are particularly significant because Georgia-Pacific has decreased its effluent flow, which would ordinarily increase specific conductance in the absence of additional improvements. After conversion to chlorine dioxide, Georgia- Pacific began monitoring for parameters defined by the Cluster Rule. In that monitoring, Georgia-Pacific has tested "non- detect" for dioxin and chlorinated phenolics. Specifically, Georgia-Pacific has monitored dioxin in its effluent, as well as within its process –- before dilution with other wastewater –- and the monitoring results at both locations are likewise "non-detect" for dioxin. Furthermore, levels of chloroform and adsorbable organic halides (AOX) have been well within the limits imposed by the proposed permit and the Cluster Rule. Georgia-Pacific has voluntarily agreed to install by April 15, 2006, an oxygen delignification system, or a like system that produces similar or better environmental benefits. Oxygen delignification is a precursor to bleaching, which removes lignins from the fiber before the product is bleached. This process is significant because lignin consumes chemicals, impedes bleaching, and prohibits achieving brightness targets in the bleach plant. The cost associated with the oxygen delignification system is $22,700,000. This commitment is reflected in the proposed Administrative Order and Permit. Oxygen delignification has been identified as having significant benefits in terms of reducing the color and specific conductance of effluent. Georgia-Pacific voluntarily agreed to install by August 15, 2003, a new brownstock washing system to replace four existing brownstock washing lines. A brownstock washer is a piece of equipment that washes organics away from fiber, after pulping and before oxygen delignification. The cost of this equipment is approximately $30,000,000. This commitment is reflected in the Administrative Order and Permit. The new brownstock washers are not required by Department rules, but they will be helpful in reducing the specific conductance of effluent. Georgia-Pacific has also voluntarily agreed to install a green liquor dregs filter. This system would remove dregs from the effluent system and reduce specific conductance and color in the effluent. The cost of the green liquor dregs filter is $1,100,000. This commitment is reflected in the Administrative Order and Permit. Under the proposed agency action, Georgia-Pacific is likewise required to install additional equipment for the implementation of its best management practices program to minimize leaks and spills in the process sewer. This equipment, including controls on the brownstock washer system, and the installation of a spill control system, pumps, and piping, has been installed at a cost of $7,100,000. Georgia-Pacific has also optimized the performance of its treatment system through the relocation of its aerators in the treatment ponds and modifying its nutrient feed system. This has led to reduced levels of biological oxygen demand (BOD) in the discharge, as well as improved treatment for total suspended solids. In addition, Georgia-Pacific has voluntarily installed a reverse osmosis system to recycle certain internal streams, which in turn has led to reductions in specific conductance, at a cost of $3,300,000. To comply with the proposed agency actions, Georgia- Pacific expects to expend a total of approximately $170,000,000 for upgrades for the purpose of producing environmental benefits. Additional money is earmarked for other environmental performance issues, such as water conservation. Except for technology-based limits adopted by rule, the Department does not dictate how a facility achieves compliance with water quality standards. Georgia-Pacific demonstrated that its environmental performance is substantially better than required by technology-based limits. Based on the foregoing, it is reasonable to find that Georgia-Pacific’s commitments to process improvements will lead to a general improvement in water quality in the receiving waters. Relocation of the Discharge As noted above, because of the minimal dilution available in Rice Creek, Georgia-Pacific has never been fully able to achieve water quality standards in Rice Creek, a Class III water body. Rice Creek continues to exceed water quality criteria for specific conductance and color; historically, the discharge had experienced exceedences for the chronic toxicity criterion. Under present conditions, with Georgia-Pacific discharging to Rice Creek and Rice Creek flowing to the St. Johns River, elevated levels of color are experienced along the shoreline of the St. Johns River in the area of existing grass beds. Modeling shows that under current flow conditions from Rice Creek, those color effects are observed on the northwest bank near the confluence of Rice Creek with the St. Johns River. If the discharge is relocated to the St. Johns River and discharged near the river bottom through a diffuser, it will beneficially change the distribution of color impacts both to Rice Creek and the St. Johns River. Color in Rice Creek will improve, returning to its background color of 100 to 150 platinum cobalt units (pcu). Specific conductance within Rice Creek will also be markedly reduced. Because the input will occur in the middle of the St. Johns River, with higher flows and greater turbulence, there will no longer be relatively highly colored water flowing along the shoreline. Therefore, the relocation will provide a significant benefit of moving highly colored water away from grass beds and will mitigate against any existing effects on those grass beds. It is beneficial to relocate discharges to the middle of a stream, as opposed to the edge of a shoreline, where effluent tends to hug the shoreline. Therefore, regardless of the process improvements, there will be a net environmental improvement by relocating the discharge to the middle of the St. Johns River The discharge from the proposed diffuser will be comparatively benign, in comparison to the present flow from Rice Creek into the St. Johns River. This is because the effluent would not reach or hug the shoreline in such a scenario but rather would be diluted in rising to the surface, as well as by its lateral movement in the direction toward the river bank. The relocation of the discharge to the middle of the St. Johns River will cause improvements through localized changes in concentrations near the diffuser and the confluence of Rice Creek and the St. Johns River. Based on the foregoing, it is found that Georgia- Pacific’s proposed discharge into the St. Johns River will not result in water quality degradation, but will instead lead to a general improvement in water quality. Proposed Conditions in the Permit and Administrative Order Before certifying completion of the required manufacturing process improvements, Georgia-Pacific is required to submit to the Department a report on its ability to optimize the modifications, as well as a separate report which would determine whether Georgia-Pacific can meet certain limits that would enable a continuing discharge to Rice Creek. If the water quality improvements are sufficient to achieve standards in Rice Creek, the permit would be reopened and Georgia-Pacific would be required to maintain the present discharge location to Rice Creek. Otherwise, Georgia-Pacific would be authorized to construct the pipeline to the St. Johns River. The permit is drafted so that Georgia-Pacific will verify the need for mixing zones, as well as the dimensions of proposed mixing zones, after process improvements are complete. The Administrative Order imposes interim effluent limitations during the compliance period described in that Order. The Administrative Order contains "report-only" conditions for certain parameters. For those parameters which do not have interim limits, there is no appropriate standard to apply because information on effluent and water quality conditions is incomplete. The Department also found it unreasonable to impose interim limits that will be met only after Georgia-Pacific completes the improvements requested by the Department. Under Department practice, it is reasonable to impose "report only" conditions for parameters when it is unclear whether the discharge for the facility presents a concern for potential exceedences of water quality standards. In addition, "report only" conditions are used when a facility is undertaking an effort to address problems for certain parameters during a period necessary to achieve compliance. The proposed permit includes mixing zones in the St. Johns River for dissolved oxygen, total recoverable iron, total recoverable cadmium, total recoverable lead, un-ionized ammonia, turbidity, and specific conductance. The length of each of those mixing zones is 16.5 meters, that is, limited to the rise of plume. A mixing zone is also required for transparency, which will require a length of 734 meters. Within 12 months after certifying completion of the manufacturing process improvements, Georgia-Pacific will be required to re-evaluate the need for mixing zones and effluent limits and re-open the permit as necessary to include final mixing zones, effluent limits, and monitoring requirements. Compliance with Ambient Water Quality Standards The Petition contends that Georgia-Pacific has not provided reasonable assurances that it would comply with the following standards: nutrients (paragraph 18); dissolved oxygen (paragraph 20); chronic toxicity (paragraph 21); total suspended solids (paragraph 23); iron (paragraph 25); and phenolic compounds (paragraph 26). Although no water quality standard is directly applicable, Petitioners also addressed the following water quality issues: biological oxygen demand (BOD) (paragraph 20); dioxin, "related compounds," chlorinated organics, AOX, and chemical oxygen demand (COD) (paragraph 22); color (paragraph 24); and total suspended solids (TSS), which is alleged to include total organic carbon (TOC) (paragraph 94). Petitioners asserted that dioxin, chlorinated organics, TSS, and AOX are significant in considering compliance with the "free-from" standard in Rules 62- 302.500(1) and 62-302.530. In determining whether water quality standards will be met, those allegations should only be considered in reference to those adopted standards for the "free-from" standard. The effluent data establishes that Georgia-Pacific will consistently meet the proposed permit limits for discharge to Rice Creek. Georgia-Pacific's treatment facility has the capacity to comply with the proposed permit limits for discharge to Rice Creek, and there is a very high degree of assurance that it has the capability to comply with those standards in the future. In addition, Georgia-Pacific's treatment facility is able to meet the WQBELs established for discharge into the St. Johns River. Evaluation and modeling demonstrate that if a discharge to the St. Johns River is undertaken, the St. Johns River will meet Class III water standards at the edge of the mixing zone if Georgia-Pacific complies with its proposed effluent limits. Also, the effluent will meet all applicable effluent guidelines and technology-based standards adopted in the Florida Administrative Code. The effluent will not settle, form deposits, or create a nuisance, and it will not float as debris, scum, or oil. Finally, the effluent will not produce color, odor, taste, or other conditions so as to create a nuisance. Georgia-Pacific performed an analysis to determine the effluent limits that would be necessary to achieve water quality standards. This analysis included water quality modeling, which is a method of summing up inputs and losses, calculating the amount of material in a system, and determining the concentration of a substance. The model was used to geometrically represent the St. Johns River, Etonia Creek, and the reach of the St. Johns River within the study area, which extended from Buffalo Bluff (15 miles upstream of the confluence of Rice Creek and the St. Johns River) to Mile Point 50. Rice Creek enters the St. Johns River at Mile Point 74. When a model is performed, the model will yield estimates or predictions of concentrations throughout a water body. Those predictions can be compared to field observations and measurements; if the model is done properly, the calculated numbers should agree with the measured numbers. Modeling is used to evaluate future conditions based on hypothetical future changes to the system. The modeling methods and advanced time-variable models employed by Georgia- Pacific's consultants were approved by the Department. Georgia-Pacific prepared a plan of study to obtain field data in the St. Johns River for the purpose of assuring that the models would simulate observed concentrations of constituents. The Department approved that plan of study and published a notice of approval. The Department also approved the quality assurance project plan for the collection of water quality data in Georgia-Pacific's modeling efforts. After approval of the plan of study and quality assurance project plan, Georgia-Pacific's consultants performed water quality surveys in November 1994 and May 1995. The models employed by Georgia-Pacific's consultants were calibrated and produced the observed water quality results. The proposed diffuser would be located about one foot from the bottom of the channel. As designed, the plume would leave the proposed diffuser and spread out, with the upper part of the plume going to the surface of the water. The plume model calculates the dilution at the centerline of the plume, where there would be a minimum of dilution. This method of using the centerline as a reference point leads to a conservative analysis, and it would require the Applicant to achieve more dilution than might otherwise be necessary to achieve water quality standards. For regulatory purposes, the Department usually uses the maximum height of the rise of the plume to determine a mixing zone, the point at which concentrations along the centerline of the plume would level off. Because of that practice, for certain parameters where the required mixing zone is less than the distance of the rise of the plume, a decrease in effluent limits would not lead to a decrease in the size of the mixing zone. Tidal actions will cause re-entrainment, that is, the movement of dissolved substances back into the plume area. This factor reduces the dilution factor that otherwise would apply to the system. This factor is accounted for in modeling by tying in a diffuser computation to a water quality model. The modeling employed by Georgia-Pacific assumes 7Q10 conditions, that is, a conservative assumption that flow is equal to the lowest one-week average for a ten-year period, where there is little dilution. The employment of this conservative method would minimize the probability of exceedences in the receiving water body. The projection employed by Georgia-Pacific's consultants was even more conservative because the 7Q10 flow rate is assumed to apply through a 60-day average flow, a condition that may never occur, and would not be expected to occur once in ten years. In contrast, the use of time-variable simulations would lead to less stringent permitting requirements. The permit provides reasonable assurance that the construction, modification, or operation of the treatment system will not discharge or cause pollution in violation of Department standards. The permit provides reasonable assurance that, based on the effluent limitations determined by the Department in the WQBEL Technical Report, water quality standards would be met outside the area of the proposed mixing zone for specific conductance, dissolved oxygen, un-ionized ammonia, iron, cadmium, lead, and zinc. Based on additional analysis as reflected in Georgia-Pacific's proposed amendment to the draft permit, Georgia-Pacific would achieve compliance with the transparency standard with the mixing zone described in its proposed amendment, that is, with a total length of 734 meters. The chronic toxicity criterion is a biological measurement which determines whether organisms are impaired by effluent. If impairment is demonstrated, the test does not indicate what component of the effluent is causing the effect. Georgia-Pacific is required to conduct testing for acute and chronic toxicity twice a year. Current tests undertaken in May and October 2001 are representative of effluent conditions after Georgia-Pacific undertook conversion of the bleach plant to chlorine dioxide. Those tests demonstrate that Georgia-Pacific is in compliance with the acute and chronic toxicity criterion since the conversion to chlorine dioxide bleaching. Georgia-Pacific is also in compliance with the biological integrity standard, based on the most recent fifth-year inspection. Because of the flow characteristics and the characteristics of pulp mill effluent, the pollutants associated with the effluent are not assimilated as the effluent travels from the point of discharge, through Rice Creek, to the St. Johns River. The particulates associated with pulp mill effluent are so small or fine that they will remain in suspension and thus not settle out in Rice Creek. In addition, because Rice Creek is channelized, there is no sloping side that would enable the growth of vegetation that would filter the water. Furthermore, even if there was a sedimentation process occurring in Rice Creek, no additional sedimentation would occur after the system reaches an equilibrium point. Although Rice Creek does cause a small decrease in BOD through oxidation, Georgia-Pacific has compensated for that factor by the injection of oxygen in the effluent. Thus, the direct piping of effluent to the St. Johns River (as opposed to a discharge into Rice Creek, which flows into the St. Johns River) would not result in any significant increase in pollutant loading to the St. Johns River. In addition, the construction of a pipeline would take place only after additional technologies have been implemented to maximize pollutant reduction. Compliance with the Reasonable Assurance Standard Georgia-Pacific has provided reasonable assurances for the proposed permit to be issued for a discharge into the St. Johns River. This finding is based upon Georgia-Pacific's ability to meet the effluent standards described in the draft permit, and modeling results demonstrating that, with the proposed mixing zones for certain parameters, a discharge into St. Johns River, as designed, will not result in a violation of Class III standards. Mixing Zones In Section H of their Petition, Petitioners challenged the proposed mixing zones set forth in the proposed Permit. Petitioners generally alleged that the proposed mixing zones were "enormous" and that they failed to comply with certain rules restricting mixing zones. In their Petition, Petitioners articulated three theories to support the proposition that the mixing zones were illegal: first, that the mixing zones would include a nursery area of indigenous aquatic life, including beds of aquatic plants of the type listed in Rule 63-302.200(16); second, that the mixing zone, by itself, would lead to a violation of the minimum criteria in Rule 62-302.500; and third, that the mixing zones, or a combination of those mixing zones, would result in a significant impairment of Class III uses in the St. Johns River. Petitioners were authorized to amend their Petition to add additional allegations to paragraphs 17 and 67 of their original Petition regarding the mixing zone. Under those amendments, Petitioners alleged that Georgia-Pacific’s proposed amendment to the draft permit would (a) improperly expand the mixing zone; (b) fail to account for the length of the diffuser; (c) improperly substitute "transparency" for "color"; and (d) prevent isolation of transparency impacts from color in the discharge. However, there is no evidence which ties those allegations to any regulatory standard that would affect the proposed agency action. Petitioners also contended that color was a surrogate for chemical oxygen demand, as well as for substances that are alleged to cause chronic or acute toxicity. However, as shown by the testimony of Department witness Maher, the permit condition for "color" was a surrogate only for the transparency standard. No evidence to support a contrary inference was presented. Petitioners also made general allegations that the proposed mixing zones are illegal, without a clear indication of what is deemed illegal about the mixing zones. Although the Petition includes a general argument in opposition to mixing zones, Petitioners were unable to suggest a legal basis for alleging that the mixing zones were illegal. For example, Petitioners alleged that certain mixing zones are enormous but failed to articulate why they are so enormous as to be illegal. They did not allege that the Department had erred by allowing a larger mixing zone than Georgia-Pacific should have received under applicable rules. Indeed, such a position would be antithetical to Petitioners' allegations that Georgia-Pacific had failed to achieve water quality standards for a number of parameters. The accepted testimony establishes that Georgia-Pacific's proposed mixing zones will comply with Department rules. No persuasive evidence was presented to the contrary. Because the effluent quality will differ from present conditions after completion of the process improvements, the proposed mixing zones will not be final until after process improvements have been made, the operation has been stabilized, and the mixing zones have been re- verified. No mixing zones are authorized in the Administrative Order. The Administrative Order contains a table setting forth potential mixing zones that are used as a benchmark to determine whether Georgia-Pacific can meet water quality standards in Rice Creek. The table sets out a series of hypothetical mixing zones at 800 meters, that is, the maximum presumptive distance afforded without additional relief mechanisms. Because no mixing zones are proposed to take effect in Rice Creek, there can be no issue of "illegal" mixing zones in Rice Creek. Within a range of potential discharge flows, from 20 MGD to 60 MGD, water quality standards will be met within the area of the proposed mixing zones for all parameters for which mixing zones are required. Mixing zones are allowed by Department rules and are considered a part of Florida water quality standards. In the context of the Department's permitting review, if a modeling analysis shows that the concentration of a pollutant in effluent is greater than the water quality criterion, the Department will determine if the amount of dilution in the receiving water is sufficient to assimilate the pollutants of concern. The Department will then determine either the length (in the case of a river) or area (in the case of an estuary) of a water body that would be necessary to achieve compliance through dilution. Based on chloride levels, the St. Johns River at the area of concern would not be considered an estuary under Department rules. Each of the proposed mixing zones would be less than 800 meters in length (as allowed by Department rule) and less than 125,600 square meters in area (a limitation that would apply only if the area was an estuary). The proposed discharge will comply with all minimum rule requirements with respect to mixing zones, such as those for dissolved oxygen, turbidity, and the absence of acute toxicity. Likewise, the proposed mixing zones will not impact any nursery areas for indigenous aquatic life. Nutrient Issues In Section I, Petitioners contested the Department's decision to not require effluent limits to prevent a violation of the narrative water quality criterion for nutrients. For reasons addressed in the undersigned's Order dated February 14, 2002, that issue is waived based because of Petitioners' failure to file a timely challenge to the WQBEL Technical Report. In addition, based on the findings set out below, Georgia-Pacific has provided reasonable assurances that it will not violate the narrative standard for nutrients. Further, the evidence shows that effluent limits for nutrients are not presently warranted. Petitioners presented testimony that the St. Johns River may be nitrogen-limited or phosphorous-limited at different times of the year, which means that concentrations of one or the other would limit algae growth at different times of the year. Relative light levels, as well as the penetration of light, also affect algae growth. Georgia-Pacific’s treatment system requires the addition of ammonia because ammonia or nitrate is a necessary nutrient for the growth of bacteria in the treatment system. Ammonia and nitrate are both nutrients. Although there can be a conversion from one form to the other, that conversion does not affect the net loss or gain of nutrients. Although nutrient issues are of concern to water bodies, it is absolutely necessary in a biological treatment system to have sufficient nutrients for the operation of the system to treat parameters such as BOD. The Georgia-Pacific facility is achieving a high level of treatment while managing its system at a minimum level of nutrient addition. Management of a treatment system requires attention not only to the influent and effluent, but also monitoring of conditions within the system itself to assure adequate treatment. Georgia-Pacific is continuing to refine its procedures for doing so. The State has adopted what is referred to as the "5- 5-3-1" (advanced wastewater treatment) limitation for municipal treatment plants that discharge to surface waters. This standard refers to five milligrams per liter for BOD, five milligrams per liter for suspended solids, three milligrams per liter for total nitrogen, and one milligram per liter for total phosphorous. This limitation has been in effect for many years and remains one of the most stringent state standards in the nation. Georgia-Pacific's facility would be in compliance with those standards for nitrogen and phosphorous. Effluent from the Georgia-Pacific mill increases the concentration of total nitrogen in Rice Creek, relative to background conditions. However, because of the relatively higher flow of the St. Johns River, when the load from the mill is transported to the St. Johns River, the increase in nitrogen concentration is so small as to be imperceptible. Nitrogen loading from Georgia-Pacific's Palatka mill on a long-term average (prior to upgrades of its treatment plant) has been measured at 1,196 pounds per day. The average loading at Buffalo Bluff, which is far upstream of Rice Creek and the Georgia-Pacific Palatka mill, is 36,615 pounds per day. Additional nonpoint sources contribute approximately 12,000 pounds per day in the study area. Thus, the loading from the Georgia-Pacific mill represents a 2.4 percent increase in nitrogen levels on the St. Johns River, a difference that cannot be measured. The largest point source of nutrients in the lower St. Johns River is the Buckman wastewater treatment plant in Duval County. That facility does not have nutrient limits on its discharge permit. Rice Creek does not provide any treatment (as opposed to dilution) for nitrogen in Georgia-Pacific's effluent. A review of probability distributions for nitrogen concentrations upstream and downstream of Rice Creek demonstrated that Rice Creek had no influence on nitrogen levels in the St. Johns River. Phosphorous concentrations from the effluent, if discharged to the St. Johns River, would dilute rapidly, decreasing to .2 milligrams per liter within the water column, five to six feet below the surface, after discharge from the diffuser, below the area in which light is absorbed at the surface of the water column. Chlorophyll-A is a parameter that is typically used as a measure of phytoplankton in the water column. Concentration distributions for chlorophyll-A at Buffalo Point (upstream of Rice Creek) matched concentrations for the same parameter at Racey Point, a station far downstream of Rice Creek. This analysis confirms that the inputs coming into the St. Johns River System from Rice Creek do not have a significant influence on the water quality of the St. Johns River, with respect to nutrients. With a discharge coming directly to the St. Johns River, and with nutrient loading being the same as from Rice Creek, the nutrient loading would not influence the St. Johns River. The Department does not have sufficient information at the present to impose a nutrient limit on Georgia-Pacific. The draft permit accounts for this issue through a re-opener clause which would authorize a limit when that information is available, if such a limit is necessary. Allegations Regarding "Deformities in Fish" Section J of the Petition includes allegations that Georgia-Pacific failed to provide reasonable assurances regarding adverse physiological response in animals under Rule 62-302.530(62), and that Georgia-Pacific has failed to provide reasonable assurances that its discharge will not be mutagenic or teratogenic to significant, locally occurring wildlife or aquatic species, or to human beings, under Rule 62- 302.500(1)(a)5. Petitioners suggest that the permit cannot be granted as proposed because it lacks effluent limits for (unstated) substances that are alleged to create potential violations of the free-from standard. This argument is barred as a matter of law for the reasons stated in the Order dated February 14, 2002. In addition, based on the following findings, this argument has been rejected because Georgia- Pacific has met the reasonable assurances standard without effluent limits on those unstated (and unknown) substances that are alleged to cause violations of those rules. Petitioners presented evidence that paper mill effluent in general contains chemicals which could cause the masculinization of the females in certain fish species, as well as hormonal effects in males. However, witness Koenig did not offer any testimony that Georgia-Pacific’s effluent, in particular, contained such chemicals. Dr. Koenig had collected no data and had not conducted any field studies in Rice Creek to support his testimony; rather, he relied on articles published by others and provided by Petitioner Linda Young. In agency practice and interpretation of the free- from standard in Rule 62-302.530(62), Florida Administrative Code, the question of whether a change is adverse depends on the overall community or population of that particular species. Tellingly, Petitioners did not present any competent evidence, through Dr. Koenig's testimony or otherwise, that Georgia-Pacific's effluent presents the potential for adverse effects on the overall community or population of any species. Dr. Koenig testified at length from his reading of studies performed by other scientists regarding changes in the hormone levels and gonadosomatic index (the relative weight of gonads) of fish in the St. Johns River in the vicinity of Rice Creek. In his testimony, Dr. Koenig relied on two published articles to address conditions in the vicinity of Rice Creek, both of which were primarily authored by M. Sepulveda. One of those articles showed hormonal changes taking place in a laboratory study where largemouth bass were exposed to mill effluent. That study also showed a change in the gonadosomatic index in the subject fish. Dr. Koenig did not offer any opinion that such changes would be adverse or that they would affect the reproduction of those fish. The other study was a field study with samples of fish at various regions in the vicinity of Rice Creek. This study did not include any fish from Rice Creek, but did include fish from the confluence of Rice Creek and the St. Johns River, as opposed to reference streams. The study showed lower levels of hormones in fish from the area of that confluence, but also showed similar effects at a reference stream 40 kilometers away. No testimony was presented to support the inference that the effects represented in the two studies were adverse, within the meaning of the free-from rule. Moreover, the data from those two studies were collected in 1996, 1997, and 1998, or before Georgia-Pacific converted its bleach plant to chlorine dioxide bleaching in March 2001. Therefore, Dr. Koenig had no data to support any theory that under current effluent conditions, Georgia-Pacific is producing or will produce compounds that would cause any changes of hormone concentrations in fish. With respect to the phenomenon of fish masculinization in Rice Creek, Petitioners' experts had no data to support a competent opinion on this subject. To support his testimony, Dr. Koenig only read one article that purported to demonstrate fish masculinization in 11-Mile Creek and the Fenholloway River, and one letter from an employee of the St. Johns River Water Management District [Young Exhibit 8A] that referred to "external anatomical anomalies" near Georgia-Pacific discharge points. The article attached to that letter and included in Young Exhibit 8A addressed data collected in Escambia County, and does not address conditions in Rice Creek. Petitioners attempted to present the theory that the potential for endocrine disruption or fish masculinization resulting from paper mill effluent would violate the free-from standard. As a condition to issuance of the permit, the Department proposes to require Georgia-Pacific to obtain approval of a plan of study to analyze the potential for significant masculinization effects from the discharge. Under the proposed conditions, Georgia-Pacific is required to determine the minimum concentration at which such effects may be detected. By its terms, the proposed permit may be reopened to adjust effluent limitations or monitoring requirements if the masculinization study shows a need for them. Department witness Brooks acknowledged a general concern for endocrine disruption resulting from paper mill effluent. In particular, Mr. Brooks referred to studies which showed that paper mill effluent could cause the elongation of an anal fin in the females of certain fish species. However, Mr. Brooks observed that although this appeared to be a physiologic response, there was no evidence or reason to believe that this effect was an adverse effect. Reports regarding masculinization, that is, the elongation of anal fins in female fish, are suspect because (among other reasons) the studies do not account for variances that would be expected based on the independent variables of sex, age, and growth. In any case, the data from those reports do not demonstrate significant, adverse effects in exposed populations. A critical and unbiased review of the published literature shows that impacts of masculinization are biologically interesting but preliminary in nature. Department witness Maher observed that the masculinization effect occurs naturally, and that the Department's plan of study is intended to determine whether this natural phenomenon becomes problematic or is enhanced by activity at the mill. Initial information reviewed by the Department indicates that the phenomenon is no longer experienced when a mill converts to a chlorine dioxide (ECF) bleaching process, as Georgia-Pacific has done in converting to ECF. According to witness Brooks, the observed effect known as "fish masculinization" is not confirmed to result from endocrine disruption. The Department has concluded that it has reason to be concerned about the potential for fish masculinization. From the Department's viewpoint, it is not clearly understood what is causing this effect. It has been shown that there is a direct relationship between concentration (or dilution) and the observation of those effects. This conclusion is consistent with Dr. Koenig's testimony, which observed a decline in observed effects based on the dosage or concentration of effluent. The Department has reviewed evidence showing that, with dilution, the effect of fish masculinization "go[es] away." In the Department's analysis of the fish masculinization issue in the present permit, the Department is requiring process improvements that would reduce this phenomenon, if it exists, in Rice Creek. In addition, if the discharge is relocated to the St. Johns River, the additional dilution would ameliorate the concern regarding fish masculinization, and the phenomenon will "go away." To give an even higher level of assurance that the resource will be protected, the Department is requiring a study to evaluate and confirm that the issue is resolved. The process changes required in the permit, the potential for further dilution in the St. Johns River if it becomes necessary, and the evaluations required in the permit condition render it very likely that any potential for fish masculinization will be mitigated. Thus, to the extent that fish masculinization could be deemed a violation of the free- from standard, Georgia-Pacific has provided reasonable assurances that it will not cause the masculinization of fish in the St. Johns River. Petitioners did not offer any credible evidence establishing that any specific compound or substance would cause the alleged effects of endocrine disruption or fish masculinization. Indeed, Dr. Koenig acknowledged that he was unable to find in his literature search the mechanism or chemical that is alleged to cause fish masculinization. Likewise, Petitioners were unable to suggest any concentration of that substance which would lead to those alleged effects. Dr. Koenig expressed a belief that chlorinated organic compounds from the paper manufacturing process may be responsible for endocrine disruption. Dr. Koenig also opined that within the general process of paper manufacturing, the bleaching process in particular was a concern. To the extent that Dr. Koenig may have had a concern regarding endocrine disruption from his review of studies performed using data from 1996 through 1998, it is reasonable to conclude that this concern is ameliorated by Georgia-Pacific's conversion to chlorine dioxide bleaching in March 2001. There is no evidence to establish a relationship between the presence or absence of dioxin and fish masculinization. Compliance with Dissolved Oxygen Standard (and BOD Concerns) In Section K, Petitioners disputed whether Georgia- Pacific had provided reasonable assurance of compliance with the adopted dissolved oxygen standard. The proposed permit contains different permit limits for BOD for winter and summer, because the impacts of discharges are different during those parts of the year. Georgia-Pacific has shown a substantial downward trend for BOD. The Georgia-Pacific facility discharges mass loadings of BOD at quantities which are much less than what is required to meet discharge standards. A review of effluent data shows that even for the worst period for performance, Georgia-Pacific's effluent was well below the proposed permit limits for BOD. A review of BOD discharges over the period of January 2000 to August 2001 demonstrates a consistent ability of the facility to meet the proposed permit limits, as well as a general trend of improvement that reflects Georgia-Pacific’s upgrade of the treatment system. Georgia-Pacific will meet the minimum standards for dissolved oxygen in mixing zones. With additional process improvements, Georgia-Pacific will also experience additional environmental benefits in the reduction of chemical oxygen demand. N. Dioxin and "Related Compounds" As to dioxin, Petitioners alleged in Section L of their Petition that Georgia-Pacific may discharge dioxin in concentrations that could cause a violation of the free-from standard. The proposed permit includes a permit condition for a plan of study to assess levels of "TCDD" and "TCDF" in fish tissue in the receiving waters. Department witness Brooks was unaware of any regulatory authority to require fish tissue sampling for dioxin. Department engineer Kohn was also uncertain of any regulatory authority for the Department to test for dioxin in fish tissue. Mr. Kohn agreed with the proposition that when a proposed permit condition is not specifically authorized by rule or statute, the condition must be withdrawn if the applicant objects. However, in this case, Georgia-Pacific did not object to the inclusion of a permit limit of .014 picograms per liter of dioxin in its final effluent. As noted above, Georgia-Pacific established that under its current effluent conditions, following conversion to chlorine dioxide bleaching, the facility is "non-detect" for dioxin. The Department does not have any adopted standards for fish tissue concentrations. Petitioners presented very little evidence of dioxin concentration in fish tissue following Georgia-Pacific's conversion to ECF bleaching, and they opposed the introduction of such data into evidence. A review of available data shows that there was not a statistically significant difference between the level of bioaccumulation of dioxin in fish tissue in Rice Creek versus a reference creek. The Florida Department of Health has concluded, based on review of prior fish tissue data, that a fish consumption advisory for Rice Creek was not warranted. Total Suspended Solids In Section M, Petitioners have alleged that TSS in the effluent would cause various environmental problems. However, Petitioners did not allege that TSS in the effluent would lead to a violation of water quality standards, and they did not present any accepted testimony or other evidence to support such a theory. There is no adopted water quality standard for TSS. According to the WQBEL Technical Report, effluent levels of TSS are generally comparable to background levels in the St. Johns River. The primary wastewater clarifier is designed to remove fiber or other settleable solids from the effluent before it travels to the secondary treatment system. Total suspended solids in Georgia-Pacific's effluent are primarily derived from biota in the treatment system, rather than fiber from the industrial process. Georgia-Pacific has shown a substantial downward trend for TSS. The facility reliably discharges TSS at quantities which are much less than what is required to meet proposed effluent limits. A review of discharge data for TSS demonstrates that Georgia-Pacific would perform in full compliance with the proposed permit limits. Petitioners presented no evidence to the contrary. Petitioners likewise presented no evidence to quantify any impacts from TSS. Color, the Transparency Standard, and Related Issues Petitioners have also alleged that the color in Georgia-Pacific's effluent would lead to nuisance conditions in violation of Rule 62-302.500(1)(a). However, they did not allege any potential violation of the one parameter traditionally associated with effluent color: the Department's transparency standard. Elevated levels of color in the effluent reduces the ability of light to penetrate into the water column, with potential effects on the growth of aquatic plants. This is translated into a "compensation point," that is, the water depth at which the light level reaches one percent. The state transparency standard prohibits a discharge from causing a decrease in the compensation point of more than ten percent, relative to natural background. The rate of decrease of light within a water column is related to increased color levels. Analysis performed by Georgia-Pacific's consultants shows that a ten percent change in compensation depth corresponds to a seventeen percent increase in color above natural background levels. Under the proposed permit, color was used as a surrogate, or alternative measure, for compliance with the transparency standard. Color was not used as a surrogate for any parameter other than transparency. Georgia-Pacific will, with additional process improvements, see additional environmental benefits in reducing the color of its effluent. For the purpose of the application, Georgia-Pacific's modeling analysis assumed that based on process improvements, its effluent would have a color of 1202 pcu. EPA's technical team had opined that Georgia- Pacific would, with process improvements, achieve a reduction in color to 500 pcu. Georgia-Pacific had opined that the improvements would achieve a color of 1202 pcu. Department witness Owen opined that the color reduction would be in a range between those two figures. Petitioners did not present any contrary evidence as to the ability of additional process improvements to reduce effluent color. Accordingly, using the most conservative (least optimistic) figure, Georgia-Pacific has provided reasonable assurances that before a discharge to the St. Johns River would be authorized, it will reduce the color of its effluent to 1202 pcu. The proposed permit takes into account the potential that Georgia-Pacific's process improvements will achieve greater improvements in color than anticipated. Under the proposed permit, the Department would reduce the size of the proposed mixing zone if Georgia-Pacific demonstrates that the color of its effluent is lower than projected. The modeling analysis further demonstrates that based on a discharge to the St. Johns River, assuming an effluent color of 1202 pcu, the change in compensation depth is greater than ten percent in the vicinity of the proposed diffuser. A 734-meter mixing zone for transparency would be required for a discharge to the middle of the St. Johns River. The required area for such a mixing zone is 64,000 square meters. Antidegradation Review In Section P, Petitioners have generally alleged that the Department failed to conduct a proper antidegradation analysis. More specifically, they alleged that the proposed discharge would reduce the quality of the receiving waters below the classification established for them. Because Georgia-Pacific presently discharges to Rice Creek, and because a separate relief mechanism (the Administrative Order) authorizes the discharge to Rice Creek, it appears that the antidegradation issues relate solely to the proposed discharge into the St. Johns River. If the relocation had resulted in degradation of the receiving water, the Department would have regulatory authority in its Rule 62-4.242(1)(c) to consider whether Georgia-Pacific could minimize its discharge through other discharge locations, the use of land application, or reuse. However, Petitioners failed to allege in their Petition that the Department misapplied that regulatory authority. Moreover, under Department practice, when a new discharge or relocation of a discharge will result in an environmental benefit, it is not necessary to conduct a review of other discharge options. The Department undertakes an antidegradation analysis in, among other scenarios, cases where a discharge will result in achievement of minimum water quality standards for a given designated use but will lead to an incremental lowering of water quality. The purpose of this analysis is to assure that the societal benefits of the discharge outweigh the cost of that incremental lowering. The proposed permit will not lead to the increase in discharge of any parameter, and the permit is more stringent and adds additional parameters or limits. In addition, there is a trend of improved performance for the treatment system. In the present case, the Department has concluded that the proposed project will result in a significant improvement in water quality by the reduction of pollutants associated with exceedences of water quality standards in Rice Creek. Regardless of whether the discharge remains in Rice Creek or is relocated to the St. Johns River, the proposed Permit and Administrative Order will lead to an improvement in water quality as opposed to a degradation of water quality. Based on improvements with respect to specific conductance parameters, the ability to relocate the discharge into the middle of the St. Johns River where better mixing will occur (relative to the confluence of Rice Creek), and anticipated improvements in grass beds, the proposed pipeline will lead to a net environmental benefit in the St. Johns River and Rice Creek. The project as set forth in the proposed Permit and Administrative Order will be clearly in the public interest because it will result in full achievement of water quality standards and full compliance with the designated use of the receiving water body. The project will result in a substantial reduction in pollutant loading in Rice Creek and the St. Johns River, regardless of the whether the discharge will be located in Rice Creek or in the St. Johns River. The Department adequately evaluated other discharge locations, alternative treatment, and disposal alternatives. Studies, including a land application pilot project, demonstrated that land application was not feasible based upon impacts to groundwater resources. In their Petition, Petitioners did not dispute the Department's analysis of those factors under applicable rules. Given these considerations, it is found that Georgia-Pacific has provided reasonable assurances that it will meet water quality standards, and it is evident that Georgia-Pacific will not reduce the quality of the St. Johns River below its Class III designation. Further, the proposed discharge will be clearly in the public interest for the purpose of antidegradation analysis. Further, the proposed discharge into the St. Johns River is important to and beneficial to the public health, safety, and welfare, taking into account the policies set forth in Rules 62-302.100 and 62-302.300, Florida Administrative Code. The proposed discharge into the St. Johns River will not adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats. Instead, the proposed discharge would provide a benefit to fish and wildlife, and their habitats. No persuasive evidence was presented that the proposed discharge to the St. Johns River would adversely affect the fishing or water-based recreational values or marine productivity in the vicinity of the proposed discharge. Indeed, the record demonstrates a beneficial effect as to those factors. The proposed discharge has not been shown to be inconsistent with the applicable Surface Water Improvement and Management Plan (SWIM plan). Rather, the evidence shows that the proposed discharge would promote the implementation of the applicable SWIM plan. Monitoring Issues Section Q in the Petition generally challenged the adequacy of proposed monitoring requirements. As to this issue, the monitoring conditions imposed in the proposed permit are sufficient to ensure compliance with the proposed permit. Petitioner Young's witness Gilbert agreed that the proposed monitoring conditions were adequate to determine the result of process changes, that the proposed monitoring conditions were comprehensive, and that those conditions were beyond what the Department normally required. The Department does not propose to engage in water quality sampling at the end of the diffuser or at the edge of the mixing zone because of the technical difficulties associated with such an endeavor. Instead, the process for determining compliance is to determine the condition of the effluent and simulate water quality conditions of the receiving water body under low-flow conditions (when the river would be most vulnerable to pollution discharges). Such an approach is more protective because it eliminates variables that may not be representative of worst-case conditions. The evidence shows that the size of Georgia- Pacific's facility renders it impracticable for Georgia- Pacific to compromise the integrity of sampling results, as suggested by Petitioners. Flow Limitations In their Petition, Petitioners also contended that the proposed agency action violates Rules 62-4.240(3)(a) and 62-620.310(9)(a) by failing to specify the volume of discharge or flows. Under Department practice, flow must be specified but is not necessarily limited. Flow was adequately specified in the proposed permit, where the facility is described as 40 MGD wastewater treatment facility with a 22 MGD expected average flow. Volume limits are indirectly set through the establishment of a mixing zone and through mass loading limits in the permit, such as the loading limits for BOD and suspended solids. When flow is increased and the concentration of the effluent remains constant, the flow would be limited by the mass limits in the permit. Furthermore, the pipe and diffuser will have a hydraulic limitation, that is, a physical limitation on the amount that can physically be discharged. The pipeline and diffuser are hydraulically limited to 60 MGD based on the current design. Over a ten-year period, Georgia-Pacific has shown a trend toward reduced effluent flow. For example, in 1991, Georgia-Pacific discharged just under 40,000,000 gallons per day (GPD). In 2001, the discharge was less than 24,000,000 GPD. As a result of water conservation measures, Georgia- Pacific has been able to achieve a substantial reduction in effluent flow even when it experienced increased storm water flow into the treatment system. Because of stormwater inputs into the treatment system, it is very difficult to set a flow limit on the discharge from a pulp and paper mill. Indeed, the Department does not typically impose volume limits on NPDES permits for pulp and paper mills. Where volume or flow limits are imposed on pulp and paper mills, they are necessary in order to assure compliance with a specific standard. The Administrative Order Georgia-Pacific has submitted plans and a reasonable schedule for constructing, installing, or placing into operation an approved pollution abatement facility or alternative waste disposal system. No contrary evidence was presented, and no alternative construction schedule was proposed by Petitioners. In assessing a schedule to achieve compliance, the Department considered the time necessary to construct additional improvements as well as the reasonableness of the time period in light of Georgia-Pacific's capital investment. As part of this analysis, the Department also considered Georgia-Pacific's commitment to go beyond what they were legally required to do in environmental upgrades. The schedule of compliance is reasonable, given the cost and magnitude of the improvements required of Georgia-Pacific. Georgia-Pacific needs permission to continue its discharge to Rice Creek for a period of time necessary to complete research, planning, construction, installation, and operation of an approved and acceptable pollution abatement facility or alternative waste disposal system. The time period described in the Administrative Order will enable Georgia-Pacific to maximize the operation of the process improvements in order to determine if the discharge can meet water quality standards in Rice Creek. Given the cost and magnitude of the improvements required in the permit and Administrative Order, the schedule of compliance set forth in the Administrative Order is reasonable. There is no present, reasonable alternative means of disposing of wastewater other than to discharge it into waters of the State. In their Petition, Petitioners contested the Department's general antidegradation analysis but did not allege that any alternative means of disposal were improperly overlooked. The Department does not have specific regulatory authority to require facilities such as Georgia-Pacific to consider re-use as part of its antidegradation analysis, as it does with domestic waste discharges. Nonetheless, the Department did look at re-use and land application and determined that they were not feasible alternatives. Although it was not specifically required to do so by rule, Georgia- Pacific had exhausted every reasonable means to re-use (rather than discharge) water from its facility. Under earlier authorizations, Georgia-Pacific was not required to achieve standards for color, conductance, and chronic toxicity in Rice Creek. The granting of an operation permit will be in the public interest. This is because Putnam County will suffer an adverse economic impact if the facility is shut down and there will be net environmental benefits achieved through compliance with the requirements set forth in the Permit and Administrative Order. The Permit requires Georgia-Pacific to submit a written report to the Department if it appears that a mixing zone is needed for chronic whole effluent toxicity.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Protection enter a final order (1) issuing proposed permit number FL0002763 to Georgia-Pacific Corporation, as set forth in Department Exhibit 175, and with the change in the permit conditions as requested in Georgia-Pacific Exhibit 102 and proposed by the Department during the hearing, and (2) approving Administrative Order No. 039-NE as set forth in Department Exhibit 176.

The Issue The issues to be determined in these consolidated cases are whether All Aboard Florida – Operations, LLC (“the Applicant”), and Florida East Coast Railway, LLC (“FECR”), are entitled to an Environmental Resource Permit Modification authorizing the construction of a stormwater management system and related activities to serve railway facilities, and a verification of exemption for work to be done at 23 roadway crossings (collectively referred to as “the project”).
Findings Of Fact The Parties Petitioners Martin County and St. Lucie County are political subdivisions of the State of Florida. Petitioners have substantial interests that could be affected by the District’s proposed authorizations. Intervenor Town of St. Lucie Village is a political subdivision of the State of Florida. Intervenor has substantial interests that could be affected by the District’s proposed authorizations. The Applicant, All Aboard Florida – Operations, LLC, is a Delaware limited liability company based in Miami. All Aboard Florida is part of a group of corporate entities formed for the principal purpose of developing and operating express passenger train service in Florida. Co-applicant Florida East Coast Railway, LLC, is a Florida limited liability company based in Jacksonville. FECR owns the existing railway corridor the passenger train service will use between Miami and Cocoa. South Florida Water Management District is a regional agency granted powers and assigned duties under chapter 373, part IV, Florida Statutes, including powers and duties related to the regulation of construction activities in wetlands. The proposed activities are within the boundaries of the District. Background The objective of the All Aboard Florida Project is to establish express passenger train service connecting four large urban areas: Miami, Fort Lauderdale, West Palm Beach, and Orlando. Most of the passenger service route, including the portion which will pass through Martin County and St. Lucie County, will use an existing railroad right-of-way used since the late 1800s. The FECR rail corridor runs along Florida’s east coast from Miami to Jacksonville. It supported passenger and freight operations on shared double mainline tracks from 1895 to 1968. The passenger service was terminated in 1968 and portions of the double track and certain bridge structures were removed. The freight service continued and remains in operation today. The passenger service will use the FECR right-of-way from Miami to Cocoa and then turn west on a new segment to be constructed from Cocoa to Orlando. The railway corridor will be operated as a joint facility, with passenger and freight trains sharing the double mainline tracks. The Applicant is upgrading the portion of the corridor between Miami and Cocoa by, among other things, replacing existing railroad ties and tracks, reinstalling double mainline tracks, and improving grade crossings. The Applicant is also installing Positive Train Control systems which provide integrated command and control of passenger and freight train movements and allow the trains to be directed and stopped remotely or automatically in the event of operator error or disability, or an obstruction on the track. The All Aboard Florida Project is being developed in two phases, Phase I extends from Miami to West Palm Beach, and Phase II from West Palm Beach to Orlando. This proceeding involves a segment within Phase II, known as Segment D09, which runs from just north of West Palm Beach to the northern boundary of St. Lucie County. The railway corridor in Segment D09 passes through Jonathan Dickinson State Park in Martin County and the Savannas Preserve State Park, parts of which are in both Martin County and St. Lucie County. Surface waters within these state parks are Outstanding Florida Waters (“OFWs”). The railway in Segment D09 also passes over the St. Lucie River using a bridge that can be opened to allow boats to pass. The Applicant plans to run 16 round trips per day between Miami and Orlando, which is about one train an hour in each direction, starting early in the morning and continuing to mid-evening. In 2013, the District issued the Applicant an exemption under section 373.406(6), which exempts activities having only minimal or insignificant adverse impacts on water resources. The 2013 exemption covers proposed work in approximately 48 of the 65 miles which make up Segment D09, and includes replacement of existing tracks and re-establishment of a second set of mainline tracks where they were historically located. The 2013 exemption covers all but 24 of the roadway crossings within Segment D09 where work is to be done in connection with the All Aboard Florida Project. In 2015, the District issued the Applicant a general permit under rule 62-330.401, which authorizes activities that are expected to cause minimal adverse impacts to water resources, for the installation of fiber optic cable along the rail bed within Segment D09. The 2013 exemption and 2015 general permit were not challenged and became final agency action. The Proposed Agency Actions The ERP Modification covers work to be done in approximately 17 of the 65 miles which make up Segment D09. The work will consist primarily of replacing existing tracks, installing new tracks, making curve modifications in some locations to accommodate faster trains, culvert modifications, and work on some fixed bridge crossings over non-navigable waters. The 2017 Exemption at issue in this proceeding covers improvements to 23 of the 24 roadway crossings that were not covered by the 2013 exemption. Proposed improvements at Southeast Florida Street in Stuart will be permitted separately. The improvements covered by the 2017 Exemption include upgrading existing safety gates and signals; installing curbs, guardrails, and sidewalks; resurfacing some existing paved surfaces; and adding some new paving. Petitioners argue that, because the District’s staff report for the ERP Modification states that the ERP does not cover work at roadway crossings, track work at roadway crossings has not been authorized. However, the staff report was referring to the roadway improvements that are described in the 2017 Exemption. The proposed track work at the roadway crossings was described in the ERP application and was reviewed and authorized by the District in the ERP Modification. “Segmentation” Petitioners claim it was improper for the District to separately review and authorize the proposed activities covered by the 2013 exemption, the 2015 general permit, the ERP Modification, and the 2017 Exemption. Petitioners contend that, as a consequence of this “segmentation” of the project, the District approved “roads to nowhere,” by which Petitioners mean that these activities do not have independent functionality. Petitioners’ argument is based on section 1.5.2 of the Applicant’s Handbook, Volume 1,1/ which states that applications to construct phases of a project can only be considered when each phase can be constructed, operated, and maintained totally independent of future phases. However, the activities authorized by the four agency actions are not phases of a project. They are all parts of Phase II of the All Aboard Florida Project, which is the passenger railway from West Palm Beach to Orlando. Section 1.5.2 is not interpreted or applied by the District as a prohibition against separate review and approval of related activities when they qualify under the District’s rules for exemptions, general permits, and ERPs. Much of Phase II is outside the District’s geographic boundaries and, therefore, beyond its regulatory jurisdiction. The District can only review and regulate a portion of Phase II. The District is unable to review this portion as a stand-alone railway project that can function independently from other project parts. The Proposed Stormwater Management System Where the Applicant is replacing existing tracks or re- establishing a second set of tracks, it will be laying new ties, ballast, and rail on previously-compacted earth. In those areas, no stormwater management modifications were required by the District. The Applicant’s new proposed stormwater management system will be located in a five-mile area of the corridor where an existing siding will be shifted outward and used as a third track. In this area, swales with hardened weir discharge structures and skimmers will be installed to provide stormwater treatment beyond what currently exists. The weir discharge structures will serve to prevent erosion at discharge points. The skimmers will serve to capture any floating oils or refuse. Because the FECR right-of-way is not wide enough in some three-track areas to also accommodate swales, the proposed stormwater management system was oversized in other locations to provide compensating volume. The District determined that this solution was an accepted engineering practice for linear systems such as railroads. Petitioners argue that the Applicant’s proposed stormwater management system is deficient because some of the proposed swales do not meet the definition of “swale” in section 403.803(14) as having side slopes equal to or greater than three feet horizontal to one foot vertical (3:1). The statute first defines a swale to include a manmade trench which has “a top width-to-depth ratio of the cross-section equal to or greater than 6:1.” The swales used in the proposed stormwater management system meet this description. Petitioners showed that the plans for one of the 46 proposed swales included some construction outside the FECR right-of-way. In response, the Applicant submitted revised plan sheets to remove the swale at issue. The Emergency Access Way The ERP application includes proposed modifications to portions of an existing unpaved emergency access way which runs along the tracks in some areas. The access way is a private dirt road for railroad-related vehicles and is sometimes used for maintenance activities. At the final hearing, Petitioners identified an inconsistency between an application document which summarizes the extent of proposed new access way construction and the individual plan sheets that depict the construction. The Applicant resolved the inconsistency by correcting the construction summary document. Petitioners also identified an individual plan sheet showing proposed access way modifications to occur outside of the FECR right-of-way. This second issue was resolved by eliminating any proposed work outside the right-of-way. Petitioners believe the proposed work on the access way was not fully described and reviewed because Petitioners believe the access way will be made continuous. However, the access way is not continuous currently and the Applicant is not proposing to make it continuous. No District rule requires the access way segments to be connected as a condition for approval of the ERP. Water Quantity Impacts An applicant for an ERP must provide reasonable assurance that the construction, operation, and maintenance of a proposed project will not cause adverse water quantity impacts to receiving waters and adjacent lands, adverse flooding to on-site or off-site property, or adverse impacts to existing surface water storage and conveyance capabilities. The District’s design criterion to meet this requirement for water quantity management is a demonstration that the proposed stormwater system will capture the additional runoff caused during a 25-year/3-day storm event. The Applicant’s proposed stormwater system meets or exceeds this requirement. Petitioners argue that the Applicant failed to provide reasonable assurance because the ERP application materials did not include a calculation of the discharge rates and velocities for water discharging from the swales during the design storm. The ERP application contains the information required to calculate the discharge rates and velocities and the Applicant’s stormwater expert, Bruce McArthur, performed the calculations and testified at the final hearing that in the areas where there will be discharges, the discharge rates and velocities would be “minor” and would not cause adverse impacts. The District’s stormwater expert, Jesse Markle, shared this opinion. Petitioners argue that this information should have been provided to the District in the permit application, but this is a de novo proceeding where new evidence to establish reasonable assurances can be presented. Petitioners did not show that Mr. McArthur is wrong. Petitioners failed to prove that the proposed project will cause adverse water quantity impacts, flooding, or adverse impacts to surface water storage and conveyance capabilities. Water Quality Impacts To obtain an ERP, an applicant must provide reasonable assurance that the construction, operation, and maintenance of a regulated project will not adversely affect the quality of receiving waters, such that state water quality standards would be violated. The District’s design criteria for water quality required the Applicant to show that its proposed stormwater system will capture at least 0.5 inches of runoff over the developed area. To be conservative, the Applicant designed its proposed system to capture 1.0 inch of runoff in most areas. Under District rules, if a stormwater system will directly discharge to impaired waters or OFWs, an additional 50 percent of water quality treatment volume is required. The proposed stormwater system will not directly discharge to either impaired waters or OFWs. In some locations, there is the potential for stormwater discharged from the proposed stormwater system to reach OFWs by overland flow, after the stormwater has been treated for water quality purposes. The Applicant designed its proposed stormwater system to provide at least an additional 50 percent of water quality treatment volume in areas where this potential exists. To ensure that the proposed construction activities do not degrade adjacent wetlands, other surface waters, or off-site areas due to erosion and sedimentation, the Applicant prepared an Erosion and Sediment Control Plan. Temporary silt fences and turbidity barriers will be installed and maintained around the limits of the construction. The District’s design criteria for water quality do not require an analysis of individual contaminants that can be contained in stormwater, except in circumstances that do not apply to this project. Compliance with the design criteria creates a presumption that water quality standards for all potential contaminants are met. See Applicant’s Handbook, V. II, § 4.1.1. Although not required, the Applicant provided a loading analysis for the proposed swales which could potentially discharge overland to impaired waters or OFWs. The analysis compared pre- and post-development conditions and showed there would be a net reduction in pollutant loading. Petitioners believe the pollutant loading analysis was inadequate because it did not specifically test for arsenic and petroleum hydrocarbons. However, the analysis was not required and adequate treatment is presumed. Petitioners did not conduct their own analysis to show that water quality standards would be violated. Petitioners’ expert, Patrick Dayan, believes the compaction of previously undisturbed soils in the emergency access way would increase stormwater runoff. However, he did not calculate the difference between pre- and post-construction infiltration rates at any particular location. His opinion on this point was not persuasive. Petitioners failed to prove that the proposed project will generate stormwater that will adversely affect the quality of receiving waters such that state water quality standards would be violated. The preponderance of the evidence shows the project complies with District design criteria and will not cause water quality violations. Soil and Sediment Contamination Petitioners argue that the ERP Modification does not account for the disturbance of existing contaminants in soils and sediments that could be carried outside of the right-of-way and into OFWs. Petitioners’ argument is based on investigations by their geologist, Janet Peterson, who collected soil, sediment, and surface water samples at 13 sites along the FECR rail corridor in the vicinity of OFWs, or surface waters that eventually flow into OFWs. During her sampling visits, Ms. Peterson saw no visual evidence of an oil spill, fluid leak, or other release of hazardous materials. Ms. Peterson compared her soil sample results to the Residential Direct Exposure Soil Cleanup Target Levels (“SCTLs”) established in rule 62-777. The SCTLs are the levels at which toxicity becomes a human health concern and the residential SCTLs assume soil ingestion of 200 mg/day for children, and 100 mg/day for adults, 350 days a year, for 30 years. Some of the soil sampling results showed exceedances of SCTLs, but the SCTLs are not applicable here because none of the sample sites are locations where children or adults would be expected to ingest soil at such levels for such lengths of time. Petitioners did not show that the contaminants are likely to migrate to locations where such exposure would occur. Ms. Peterson compared her soil sample results to the Marine Surface Water Leachability SCTLs, but she did not develop site-specific leachability-based SCTLs using DEP’s approved methodology. Nor did she show that the proposed project will cause the soils to leach the contaminants. Ms. Peterson collected sediment samples from shorelines, but not where construction activities are proposed. She compared her sediment sample results to the Florida Department of Environmental Protection’s (“DEP”) Sediment Quality Assessment Guidelines (“SQAGs”). These guidelines are not water quality standards. Any exceedance of these guidelines requires further analysis to determine potential water quality impacts. Ms. Peterson did not conduct the analysis. Ms. Peterson acknowledged that there are numerous sources for these pollutants at or near her sample sites, such as high-traffic roads, vehicular bridges, commercial and industrial facilities, boatyards, and golf courses. She did not establish baselines or controls. Ms. Peterson collected surface water samples at seven sites, some of which were located outside the FECR right-of-way. The results showed levels of phosphorous and nitrogen above the criteria for nutrients at some locations. Phosphorous, nitrogen, and the other nutrients are prevalent in the waters of Martin County and St. Lucie County and come from many sources. Petitioners’ evidence focused on existing conditions and not expected impacts of the proposed project. The evidence was insufficient to prove the proposed project will cause or contribute to water quality violations. Functions Provided by Wetlands and Other Surface Waters An applicant for an ERP must provide reasonable assurance that a proposed project will not adversely impact the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters. Petitioners claim the Applicant and District should not have relied on Florida Land Use Cover and Forms Classification System (“FLUCCS”) maps to identify and characterize wetlands and other habitat areas because the maps are too general and inaccurate. However, the FLUCCS maps were not used by the Applicant or District to evaluate impacts to wetlands or other habitats. The Applicant began its evaluation of impacts to wetlands and other habitat areas by field-flagging and surveying the wetland and surface water boundaries in the project area using a GPS device with sub-meter accuracy. It then digitized the GPS delineations and overlaid them with the limits of construction to evaluate anticipated direct impacts to wetlands and other surface waters. The District then verified the delineations and assessments in the field. The Applicant and District determined that there are a total of 4.71 acres of wetlands within the FECR right-of-way, including tidal mangroves, freshwater marsh, and wet prairie. They also determined the proposed project will directly impact 0.35 acres of wetlands, consisting of 0.09 acres of freshwater marsh and 0.26 acres of mangroves. Petitioners contend that the Applicant failed to account for all of the project’s wetland impacts, based on the wetland delineations made by their wetland expert, Andrew Woodruff. Most of the impacts that Mr. Woodruff believes were not accounted for are small, between 0.01 and 0.05 acres. The largest one is acres. The Applicant’s delineations are more reliable than Mr. Woodruff’s because the methodology employed by the Applicant had greater precision. It is more likely to be accurate. Petitioners argue that the 2013 exemption and the 2015 general permit did not authorize work in wetlands and, therefore, the impacts they cause must be evaluated in this ERP Modification. However, Petitioners did not prove that there are unaccounted-for wetland impacts associated with those authorizations. Any impacts associated with best management practices for erosion control, such as the installation of silt fences, would be temporary. The District does not include such temporary minor impacts in its direct, secondary, or cumulative impacts analyses. Most of the wetlands that would be directly impacted by the ERP Modification are degraded due to past hydrologic alterations and soil disturbances from the original construction and historical use of the FECR railway corridor, and infestation by exotic plant species. Most of these wetlands are also adjacent to disturbed uplands within or near the rail corridor. The functional values of most of the wetlands that would be affected have been reduced by these disturbances. The Applicant provided reasonable assurance that the project will not adversely impact the value of functions provided to fish and wildlife and listed species by wetlands and other surface waters. Secondary Impacts Section 10.2.7 of the Applicant’s Handbook requires an applicant to provide reasonable assurance that the secondary impacts from construction, alteration, and intended or reasonably expected uses of a proposed activity (a) will not cause or contribute to violations of water quality standards or adverse impacts to the functions of wetlands or other surface waters; (b) will not adversely impact the ecological value of uplands for bald eagles, and aquatic or wetland-dependent listed animal species for nesting or denning by these species; (c) will not cause impacts to significant historical or archaeological resources; and (d) additional phases for which plans have been submitted, and closely linked projects regulated under chapter 373, part IV, will not cause water quality violations or adverse impacts to the functions of wetlands or other surface waters. The proposed work will be entirely within the limits of the existing railway corridor where secondary impacts to wetlands and other surface waters caused by noise, vibration, fragmentation of habitats, and barriers to wildlife have existed for decades. The preponderance of the evidence shows that any increase in these kinds of impacts would be insignificant and would not reduce the current functions being provided. Because the affected wetlands are not preferred habitat for wetland-dependent, endangered, or threatened wildlife species, or species of special concern, and no such species were observed in the area, no adverse impacts to these species are expected to occur. Petitioners contend that adverse impacts will occur to the gopher tortoise, scrub jay, and prickly apple cactus. These are not aquatic or wetland-dependent species. However, the preponderance of the evidence shows any increase in impacts to these species would be insignificant. When the train bridges are closed, boats with masts or other components that make them too tall to pass under the train bridges must wait for the bridge to open before continuing. Petitioners contend that the current “stacking” of boats waiting for the bridges to open would worsen and would adversely impact seagrass beds and the West Indian Manatee. However, it was not shown that seagrass beds are in the areas where the boats are stacking. The available manatee mortality data does not show a link between boat stacking and boat collisions with manatees. Mr. Woodruff’s opinion about increased injuries to manatees caused by increased boat stacking was speculative and unpersuasive. The preponderance of the evidence shows that the adverse effects on both listed and non-listed wildlife species, caused by faster and more numerous trains would be insignificant. The activities associated with the 2013 exemption and the 2015 general permit for fiber optic cable were based on determinations that the activities would have minimal or insignificant adverse impacts on water resources. These determinations are not subject to challenge in this proceeding. The Applicant provided reasonable assurance that the secondary impacts of the project will not cause or contribute to violations of water quality standards, adversely impact the functions of wetlands or other surface waters, adversely impact the ecological value of uplands for use by listed animal species, or cause impacts to significant historical or archaeological resources. Elimination and Reduction of Impacts Under section 10.2.1.1 of the Applicant’s Handbook, if a proposed activity will result in adverse impacts to wetlands and other surface waters, the applicant for an ERP must implement practicable design modifications to eliminate or reduce the impacts, subject to certain exceptions that will be discussed below. Petitioners argue that this rule requires the Applicant and District to evaluate the practicability of alternative routes through the region, routes other than the existing railway corridor in Segment D09. As explained in the Conclusions of Law, that argument is rejected. The evaluation of project modifications to avoid impacts was appropriately confined to the railway corridor in Segment D09. The Applicant implemented practicable design modifications in the project area to reduce or eliminate impacts to wetlands and other surface waters. Those modifications included the shifting of track alignments, the elimination of certain third-track segments, and the elimination of some proposed access way modifications. However, the project qualified under both “opt out” criteria in section 10.2.1.2 of the Applicant’s Handbook so that design modifications to reduce or eliminate impacts were not required: (1) The ecological value of the functions provided by the area of wetland or surface water to be adversely affected is low, and the proposed mitigation will provide greater long-term ecological value; and (2) the applicant proposes mitigation that implements all or part of a plan that provides regional ecological value and provides greater long-term ecological value. Mitigation The Applicant proposes to mitigate for impacts to wetlands by purchasing mitigation credits from four District- approved mitigation banks: the Bluefield Ranch, Bear Point, Loxahatchee, and F.P.L. Everglades Mitigation Banks. Each is a regional off-site mitigation area which implements a detailed management plan and provides regional long-term ecological value. The number of mitigation credits needed to offset loss of function from impacts to wetlands was calculated using the Modified Wetland Rapid Assessment Procedure (“MWRAP”) or Wetland Assessment Technique for Environmental Review (“WATER”), as prescribed in the state permit for each mitigation bank. Applying these methods, the Applicant is required to purchase mitigation credits. The Applicant proposed to mitigate the adverse impacts to freshwater marsh wetlands by purchasing 0.01 freshwater herbaceous credits from the Bluefield Ranch Mitigation Bank, and 0.06 freshwater herbaceous credits from the Loxahatchee Mitigation Bank. The adverse impacts to tidal mangrove wetlands would be mitigated by purchasing 0.12 saltwater credits from the Bear Point Mitigation Bank, and 0.02 saltwater credits from the F.P.L. Everglades Mitigation Bank. The Applicant committed to purchase an additional 0.29 freshwater herbaceous credits from the Bluefield Ranch Mitigation Bank, for a total of 0.50 mitigation credits. The proposed mitigation implements a plan that will provide greater long-term ecological value than is provided by the wetlands that will be impacted. The Applicant proved by a preponderance of the evidence that the project complies with the District’s mitigation requirements. Cumulative Impacts To obtain an ERP, an applicant must provide reasonable assurance that a regulated activity will not result in unacceptable cumulative impacts to water resources. This assurance can be provided by proposing to fully mitigate the impacts within the same basin. However, when an applicant proposes mitigation in another drainage basin, the applicant must demonstrate that the regulated activity will not cause unacceptable cumulative impacts. The proposed project will adversely impact 0.02 acres of freshwater marsh wetlands and 0.21 acres of tidal mangrove wetlands in the St. Lucie River basin. The impacts to the freshwater marshes must be mitigated out-of-basin because there are no mitigation banks in the basin which offer freshwater herbaceous mitigation credits. The proposed project will adversely impact 0.07 acres of the freshwater marshes and 0.05 acres of the mangrove wetlands in the Loxahatchee River basin. Those impacts must also be mitigated out-of-basin because there are no mitigation banks in the Loxahatchee River basin. Because some of the Applicant’s proposed mitigation must be provided out-of-basin, the ERP application included a cumulative impact analysis. The analysis evaluated whether the proposed project, when considered in conjunction with other possible development within the St. Lucie River and Loxahatchee River drainage basins, would result in unacceptable cumulative impacts considering each basin as a whole. There are approximately 10,068 acres of freshwater marshes within the St. Lucie basin, of which an estimated 4,929 acres are not preserved and would be at risk of potential future development. The proposed project will adversely impact 0.02 of those acres, which is only 0.0004 percent of the total at-risk acreage. There are about 34,000 acres of freshwater marshes within the Loxahatchee River basin, of which an estimated 7,463 acres are at risk of future development, and approximately 564 acres of tidal mangrove wetlands, of which an estimated 75 acres are at risk of future development. The project will adversely impact 0.07 acres of the freshwater marshes (0.0009 percent), and 0.05 acres of the tidal mangrove wetlands (0.0667 percent). Petitioners contend the Applicant’s analysis did not account for impacts from proposed activities authorized in the 2013 and 2015 general permit. However, Petitioners failed to prove there are unaccounted-for wetland impacts. The preponderance of the evidence supports the District’s determination that the proposed project will not cause unacceptable cumulative impacts to wetlands and other surface waters. Public Interest When an applicant seeks authorization for a regulated activity in, on, or over wetlands or surface waters, it must provide reasonable assurance that the activity will not be contrary to the public interest, or if the activity is within or significantly degrades an OFW, is clearly in the public interest, as determined by balancing the following criteria set forth in section 373.414(1)(a): Whether the activities will adversely affect the public health, safety, or welfare or the property of others; Whether the activities will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; Whether the activities will adversely affect navigation or the flow of water or cause harmful erosion or shoaling; Whether the activities will adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity; Whether the activities will be of a temporary or permanent nature; Whether the activities will adversely affect or will enhance significant historical and archaeological resources; and The current condition and relative value of functions being performed by areas affected by the proposed activities. The proposed work is not within an OFW, but entirely within the FECR corridor. The potential for overland flow and indirect impacts to OFWs is addressed by additional treatment of the stormwater prior to discharge. The proposed project would not significantly degrade an OFW. Therefore, the applicable inquiry is whether the project is contrary to the public interest. Factor 1: Public Safety, Safety, and Welfare Petitioners contend that the proposed project will adversely affect public health, safety, and welfare by impacting water quantity, water quality, and certain non-environmental matters such as emergency response times, traffic congestion, and potential train collisions with pedestrians and vehicles. Potential environmental impacts have been addressed above and, by a preponderance of the evidence, the District and the Applicant showed that such impacts would be insignificant or would be mitigated. As to the potential for non-environmental impacts associated with train operations, it is explained in the Conclusions of Law that the public interest test does not include consideration of non-environmental factors other than those expressly articulated in the statute, such as navigation and preservation of historical or archaeological resources. However, because evidence of non-environmental impacts was admitted at the final hearing, the issues raised by Petitioners will be briefly addressed below. The regulatory agency with specific responsibility for railroad safety is the Federal Railroad Administration (“FRA”). The FRA reviewed the safety features associated with the proposed passenger train operations, and approved them. Public safety will be enhanced at roadway crossings because of the proposed improvements and the use of modern technology in monitoring and managing the movement of trains. Petitioners contend that the addition of the passenger rail service will impede emergency response times in Martin County and St. Lucie County due to more frequent roadway closures. However, freight trains currently impede emergency response times due to their length and slow speed. The passenger trains will be much shorter in length and faster so that roadway crossing closures for passing passenger trains will be much shorter than for freight trains. The ERP Modification and 2017 Exemption do not affect freight train operations. The preponderance of the evidence shows that passenger rail service is unlikely to cause a material increase in the occurrence of circumstances where an emergency responder is impeded by a train. The current problem must be addressed through changes in freight train operations. Petitioners also contend that the passenger rail service will interfere with hurricane evacuation. The persuasive evidence does not support that contention. Train service would cease when a hurricane is approaching. Petitioners contend the trains will have to be “staged” on either side of the two moveable bridges while other trains cross, thereby blocking road intersections. However, this was a matter of speculation. The Applicant does not propose or want to stage trains at the bridges. Petitioners contend that the project will cause hazards to boaters on the St. Lucie River because there will be more times when the train bridge will be closed to allow the passage of passenger trains. Although there were many statistics presented about the number of boats affected, the evidence was largely anecdotal with respect to the current hazard associated with boaters waiting for the passage of freight trains and speculative as to the expected increase in the hazard if shorter and faster passenger trains are added. Factor 2: Conservation of Fish and Wildlife As previously found, the proposed activities will not adversely affect the conservation of fish and wildlife, including threatened or endangered species. The preponderance of the evidence shows the project will have only insignificant adverse impacts on water resources and wildlife. Factor 3: Navigation of the Flow of Water Petitioners claim the project will hinder navigation on the St. Lucie and Loxahatchee Rivers because of the increase in bridge closures if passenger trains are added. The U.S. Coast Guard is the agency with clear authority to regulate the opening and closing of moveable train bridges over navigable waters in the interests of navigation. Petitioners’ insistence that the District address the bridge openings is novel. No instance was identified by the parties where this District, any other water management district, or DEP has attempted through an ERP to dictate how frequently a railroad bridge must open to accommodate boat traffic. The Coast Guard is currently reviewing the project’s potential impacts on navigation and will make a determination about the operation of the moveable bridges. It has already made such a determination for the moveable bridge which crosses the New River in Ft. Lauderdale. Petitioners point to section 10.2.3.3 of the Applicant’s Handbook, which states that the District can consider an applicant’s Coast Guard permit, and suggest that this shows the District is not limited to what the Coast Guard has required. However, Section 10.2.3.3 explains the navigation criterion in terms of preventing encroachments into channels and improving channel markings, neither of which encompasses the regulation of train bridges. The preponderance of the evidence shows the project would not cause harmful erosion or shoaling or adversely affect the flow of water. Factor 4: Fishing, Recreational Values, and Marine Productivity The preponderance of the evidence shows that there would be no adverse impacts or only insignificant impacts to fishing or recreational values and marine productivity. Factor 5: Permanent Impact The proposed project will have both temporary and permanent impacts. The temporary impacts include the installation of silt fences and turbidity barriers designed to reduce water quality impacts and impacts to functions provided by wetlands and surface waters. The impacts due to track installation, construction and rehabilitation of the non-moveable bridges, at-grade crossing improvements, and stormwater system improvements are permanent in nature. The permanent impacts have been minimized and mitigated. Factor 6: Historical or Archaeological Resources Petitioners do not contend that the project will adversely affect significant historical or archaeological resources. Factor 7: Wetland Functions in Areas Affected Because the proposed work is within the limits of an existing railway corridor where impacts have been occurring for decades, and the majority of the wetlands to be affected are of a low to moderate quality, there would be only a small loss of functional values and that loss would be fully mitigated. Public Interest Summary When the seven public interest factors are considered and balanced, the proposed project is not contrary to the public interest. Even if Petitioners’ non-environmental issues are included, the project is not contrary to the public interest. Compliance With Other Permit Conditions The project is capable, based on accepted engineering and scientific principles, of performing and functioning as proposed. The Applicant demonstrated sufficient real property interests over the lands upon which project activities will be conducted. It obtained the required consent for proposed activities relating to bridge crossings over state-owned submerged lands. The Applicant provided reasonable assurance of compliance with all other applicable permit criteria. Exemption Verification for Roadway Crossings The Applicant’s ERP application included a mixture of activities which required an individual permit, as well as activities in roadway crossings which the Applicant claimed were exempt from permitting. Pursuant to section 5.5.3.4 of the Applicant’s Handbook, the Applicant requested a verification of exemption as to certain work to be done within 23 of those 24 roadway crossings. The District determined that the improvements for which an exemption was sought were exempt from permitting under rule 62-330.051(4)(c) for minor roadway safety construction, rule 62-330.051(4)(d) resurfacing of paved roads, and rule 62-330.051(10) for “construction, alteration, maintenance, removal or abandonment of recreational paths for pedestrians, bicycles, and golf carts.” The preponderance of the evidence shows the proposed work qualifies for exemption under these rules.
