The Issue The issue to be determined in this case is whether the proposed amendment to Florida Administrative Code Rule 62-555.360 of the Department of Environmental Protection (“Department”), pertaining to cross-connection control for public water systems, is an invalid exercise of delegated legislative authority.
Findings Of Fact The Parties Petitioner is a natural person residing at 1805 Burlington Circle, Sun City Center, Hillsborough County, Florida. The Department is the state agency with powers and duties to protect public drinking water as set forth in the Florida Safe Drinking Water Act, section 403.850, et seq., Florida Statutes (2013). Background The term “cross-connection” is defined in rule 62-550.200(26) as: any physical arrangement whereby a public water supply is connected, directly or indirectly, with any other water supply system, sewer, drain, conduit, pool, storage reservoir, plumbing fixture, or other device which contains or may contain contaminated water, sewage or other waste, or liquid of unknown or unsafe quality which may be capable of imparting contamination to the public water supply as the result of backflow. Cross-connections are prohibited unless appropriate backflow protection is provided to prevent backflow through the cross-connection into the public water system. See Fla. Admin. Code R. 62-550.360(1). There are three types of backflow prevention devices germane to this proceeding: Reduced Pressure Principle Assembly ("RP"), Double Check Valve Assembly ("DC"), and Dual Check Device ("DuC”). Typically, but not in every case, the water customer is responsible for the costs of installation, inspection, and maintenance of a backflow prevention device. It is undisputed that the RP is the most expensive to purchase, install, and maintain; followed by the DC; and then the DuC.2/ The RP and DC are installed above-ground, usually near a street. Test ports on these assemblies allow them to be tested to determine whether they are still functioning to prevent backflow. The DuC is usually installed underground and has no test ports. The Department asserts that this difference makes the DuC less reliable than the RP and DC. The rule states, and Petitioner did not refute, that the RP and DC offer greater backflow protection than the DuC. Petitioner has an auxiliary water system at his residence, which he uses to pump untreated water from a nearby lake to irrigate his lawn. There is no cross-connection between the plumbing system in Petitioner’s residence and his auxiliary water system. Petitioner does not have a backflow prevention device installed at his property. Hillsborough County has an ordinance that requires the installation of an RP device for residential customers who have auxiliary water systems, but the County currently has a moratorium on the enforcement of its ordinance. Petitioner is on a local committee established to investigate and advise the Hillsborough County Board of County Commissioners regarding cross-connection control. He believes the County is likely to modify its ordinance and allow the DuC for residential customers who have auxiliary water systems. The Department Rule The Department stated its purposes for the rule in the Notice of Proposed Rulemaking: These rules are being amended to significantly reduce the overall regulatory burden of cross-connection control requirements on community water systems (CWSs) and their residential customers by: allowing a dual check device to be used as backflow protection at or for residential service connections from CWSs to premises where there is any type of auxiliary or reclaimed water system; and (2) allowing biennial instead of annual testing of backflow preventer assemblies required at or for residential service connections from CWSs. A community water system (“CWS”) is a public water system which serves at least 15 service connections or regularly serves at least 25 year-round residents. See § 403.852(3), Fla. Stat. The Department requires each CWS to have a cross- connection control program, and Table 62-555.360-2 in the rule establishes the “Minimum Backflow Protection” that must be provided at or for the service connection from the CWS to various types of water customers. The minimum backflow protection specified in the table for a residential service connection with an auxiliary water system is a DuC. All references hereafter to “residential service connection” shall mean one with an auxiliary water system. There is a footnote for the DuC at the bottom of the table, which explains: A DuC may be provided only if there is no known cross-connection between the plumbing system and the auxiliary or reclaimed water system on the customer's premises. Upon discovery of any cross•connection between the plumbing system and any reclaimed water system on the customer's premises, the CWS shall ensure that the cross-connection is eliminated. Upon discovery of any cross- connection between the plumbing system and any auxiliary water system other than a reclaimed water system on the customer's premises, the CWS shall ensure that the cross-connection is eliminated or shall ensure that the backflow protection provided at or for the service connection is equal to that required at or for a non•residential service connection. The SERC As part of the rulemaking process for the proposed amendments to rule 62-555.360, the Department prepared a Statement of Estimated Regulatory Cost ("SERC"). Section 120.541, Florida Statutes (2013), governs the preparation of SERCs and provides that a substantially affected person may submit a “good faith written proposal for a lower cost regulatory alternative that substantially accomplishes the objectives of the law being implemented.” See § 120.541(1)(a), Fla. Stat. The parties dispute whether Petitioner challenged the SERC. In his amended petition, Petitioner states no objection to any statement in the SERC. Petitioner did not challenge the SERC. The parties dispute whether Petitioner submitted a lower cost regulatory alternative. The Notice of Proposed Rulemaking stated: Any person who wishes to provide information regarding a statement of estimated regulatory costs or provide a proposal for a lower cost regulatory alternative must do so in writing within 21 days of this notice. Within 21 days of the notice, the Department received Petitioner's written comments. In his comments, Petitioner cites section 120.52(8)(f), which provides that a rule is invalid if it imposes regulatory costs which could be reduced by adopting a less costly alternative. Petitioner recommends that the rule be changed to specify that the less costly DuC is the only acceptable backflow prevention device for residential service connections and “A CWS shall not impose a requirement for a more expensive type of backflow prevention valve.” The Department contends that Petitioner’s comments did not constitute a good faith lower cost regulatory alternative, citing pages 87-98 of the Transcript. Those pages contain some argument on the issue, but do not prove Petitioner did not submit a lower cost regulatory alternative. Petitioner’s timely written comments included a citation to the relevant statute and a plainly-worded proposal. As explained in the Conclusions of Law, Petitioner’s comments were sufficient to constitute a lower cost regulatory alternative. Petitioner’s Objections Petitioner objects to rule 62-555.360 because (1) it specifies use of the RP and DC, which he contends are unreasonably dangerous to public health and safety; (2) it specifies the DuC for residential service connections as the “minimum” protection, which he contends allows a CWS to require the more expensive RP or DC; (3) it requires testing of backflow devices “at least biennially” (once every two years), which he believes is too frequent; (4) it makes biennial testing a “minimum” testing interval, which he contends allows a CWS to require more frequent inspection; and (5) it does not require the backflow prevention device to be attached to the CWS’s water meter where Petitioner believes it should always be located. Unreasonable Danger Petitioner contends that the RP and DC are unreasonably dangerous to public health and safety because a person could intentionally pump contaminants through a test port on one of these assemblies into a public water supply. The Department does not dispute that a person could introduce contaminants into a public water supply in this way. The flaw in Petitioner’s reasoning is his failure to see the danger in proper perspective. Department personnel and other persons with expertise in public water systems throughout the United States are well aware that there are many access points in potable water collection, treatment, and distribution systems and many methods to introduce contaminants into these systems. There are many access points other than RPs and DCs. For example, there are methods available that would allow contaminants to be pumped into a public water system from any building connected to the system that has no backflow prevention device installed. RPs and DCs are primarily designed to prevent accidental introduction of contaminants into a public water system. However, they also prevent a person from intentionally pumping contaminants into the public water system from inside a house or building, hidden from view. The danger described by Petitioner assumes that the criminal who is intentionally pumping contaminants through the RP or DC will do it while standing next to the device, in the open, near a street. It is a well-known fact officially recognized by the Administrative Law Judge that criminals prefer to conduct their criminal activities hidden from sight rather than in plain view. Therefore, a criminal planning to contaminate a public water supply is more likely to choose a means other than introducing contaminants through an RP or DC. RPs and DCs are already in wide use. There is no reported incident of intentional contamination of a public water supply by pumping contaminants through one of these devices. When these factors are taken into account, the rule’s specifications for the continued use of RPs and DCs do not create an unreasonable danger to the public health and safety. Minimum Backflow Protection Petitioner contends that Table 62-555.360-2 is invalid because it violates the Department’s duty under section 120.541 to adopt “less costly alternatives.” Petitioner asserts that by specifying the DuC as the “minimum” backflow protection required for residential service connections the rule allows a local government to require the more costly RP or DC. The Department cannot dispute that the DuC substantially accomplishes the statutory objectives. The RP and DC provide greater backflow protection than the DuC, but the Department specified the DuC for residential service connections, indicating that the lower protection provided by the DuC did not make it fall short of the statutory objectives. However, as explained in the Conclusions of Law, the rule imposes the least costly regulatory alternative for residential service connections because it only requires the DuC. Biennial Testing Schedule Petitioner contends that section III.D. of Table 62-555.360-1 also violates the Department’s duty to adopt less costly alternatives because the rule requires “backflow assemblies” to be tested biennially, which Petitioner believes is too frequent. The term “backflow preventer assemblies” refers only to the RP and DC. See footnote 1 of Table 62-555.360-1. Section III.E. of Table 62-555.360-1 indicates that the DuC must be refurbished or replaced “at least once every 5 to 10 years.” Petitioner did not object to this requirement. The preponderance of the evidence presented shows that biennial testing is reasonable. Furthermore, it is determined in the Conclusions of Law that Petitioner has no standing to object to the testing frequency specified for the RP and DC, because the rule does not require him to have an RP or DC. Location of the Backflow Preventer Petitioner objects to section III.B. of Table 62-555.360-1, which requires backflow prevention devices to be “installed as close as practical to the CWS’s meter or customer’s property line.” Petitioner contends that this is an unconstitutional interference with private property and is unreasonably dangerous because it provides a means for intentional contamination. Petitioner’s private property rights claim is based on his allegation that if he were required by Hillsborough County to have an RP and DC, the device could be placed on his private property. Petitioner did not allege or present evidence to show that placing an RP or DC on his property would deprive him of all reasonable uses of his property so as to cause a taking of his private property for a public purpose without full compensation. See Art. X, § 6(a), Fla. Const. Furthermore, it is determined in the Conclusions of Law that Petitioner has no standing to raise this issue because the rule does not require him to have an RP or DC. Petitioner contends the rule should require that backflow prevention devices always be attached to the water meter because that reduces the opportunity for intentional contamination. Petitioner is not an expert in public water systems, generally, or the installation of backflow prevention devices, in particular. He is not competent to state the relevant factors and constraints associated with installation of the devices. He is not competent to express an opinion whether it is always possible or always appropriate to attach the devices directly to the water meter. Furthermore, Petitioner’s claim of unreasonable danger was refuted above.
The Issue The issue is whether the applicant for an Environmental Resource Permit ("ERP"), the City of Deltona ("City" or "Applicant"), has provided reasonable assurance that the system proposed complies with the water quantity, environmental, and water quality criteria of the St. Johns River Water Management District's ("District") ERP regulations set forth in Florida Administrative Code Chapter 40C-4, and the Applicant's Handbook: Management and Storage of Surface Waters (2005).
Findings Of Fact The District is a special taxing district created by Chapter 373, Florida Statutes, charged with the duty to prevent harm to the water resources of the District, and to administer and enforce Chapter 373, Florida Statutes, and the rules promulgated thereunder. The City of Deltona is a municipal government established under the provisions of Chapter 165, Florida Statutes. The Lake Theresa Basin is comprised primarily of a system of interconnected lakes extending from Lake Macy in the City of Lake Helen to the Butler Chain of Lakes (Lake Butler and Lake Doyle). The Lake Theresa Basin is land-locked and does not have a natural outfall to Lake Monroe and the St. Johns River. In 2003, after an extended period of above-normal rainfall in the Deltona area, the lakes within the land-locked Lake Theresa Basin staged to extremely high elevations that resulted in standing water in residential yards, and rendered some septic systems inoperable. Lake levels within the Lake Theresa Basin continued to rise and were in danger of rising above the finished floor elevations of some residences within the basin. On March 25, 2003, the District issued an Emergency Order (F.O.R. No. 2003-38) authorizing the construction and short-term operation of the Lake Doyle and Lake Bethel Emergency Overflow Interconnection. Since wetland and surface water impacts would occur, the Emergency Order required the City of Deltona to obtain an ERP for the system. The project area is 4.1 acres, and the system consists of a variable water structure on the west shore of Lake Doyle connected to a series of pipes, swales, water control structures, and wetland systems which outfall to a finger canal of Lake Bethel, with ultimate discharge to Lake Monroe and the St. Johns River. The first segment of the system extends downstream from the weir structure on the west shore of Lake Doyle via a pipe entrenched in the upland berm of the Sheryl Drive right-of-way. The pipe passes under Doyle Road and through xeric pine-oak uplands to the northeast shore of a large (approximately 15 acres) deepwater marsh. Water flows south through the deepwater marsh where it outfalls through four pipes at Ledford Drive. Two of the four pipes are overflow structures, controlled by canal gates. The pipes at Ledford Drive discharge into a ditch and into a large (greater than 20 acres) shallow bay swamp. The south end of the bay swamp is defined (and somewhat impounded) by a 19th Century railroad grade. Water flows through the bay swamp where it outfalls through five pipes at the railroad grade. Three of the five pipes are overflow structures, controlled by channel boards. The pipes at the railroad grade discharge to a 1500-foot long finger canal that was dug some time during the period 1940-1972 from the north central shore of Lake Bethel. The overflow interconnection system has three locations whereby the system can be shut down: 1) Lake Doyle--a control weir, controlled by three sluice gates; 2) Ledford Drive--two thirty-inch reinforced concrete pipes, controlled by canal gates; and 3) railroad grade--three thirty-inch reinforced concrete pipes, controlled by channel boards (collectively referred to as "Overflow Structures"). The Overflow Structures are designed to carry the discharge of water from Lake Doyle to Lake Bethel. With the Overflow Structures closed the system returns to pre-construction characteristics, meaning there will be no increase or decrease in the quantity or quality of water throughout the path of the system as a result of the project. An unequivocal condition of the permit is that the system would operate with all of the Overflow Structures closed. As an added assurance, the City proposes to place a brick and mortar plug in the Lake Doyle weir structure outfall pipe to prevent any discharge from the weir. The City has submitted to the District preliminary plans for a future phase in which the system would be modified for the purpose of alleviating high water levels within the Lake Theresa Basin when the water level in Lake Doyle rises above an elevation of 24.5 feet. The District shall require a separate permit application to be submitted for such future plans. Petitioner, Barbara Ash, has lived on Lake Theresa for 19 years. Ms. Ash lives upstream from the area of the weir that will be plugged in accordance with the ERP. She does not trust either the City of Deltona to comply with or the District to enforce the conditions of the ERP applied for by the City. Petitioner, Barbara Ash, also served as the qualified representative for Petitioners, Francell Frei, Bernard J. and Virginia Patterson, and Ted and Carol Sullivan. Ms. Ash represented that Ms. Frei has lived on Lake Theresa for 12 years, and both the Pattersons and the Sullivans live on Lake Louise, which is within the area of concern in this proceeding. Petitioner, Diana Bauer, has lived on Lake Theresa since February 2004. She fears that the lake will become too dry if the system is allowed to flow. She also believes the wildlife will be adversely affected if the water levels are too low since many species need a swampy or wet environment to thrive. She fears her property value will decrease as a result of the approval of the ERP. She also does not trust either the City to comply with or the District to enforce the conditions of the ERP. Petitioner, Howard Ehmer, lives two to three hundred yards down Lake Theresa from Ms. Bauer. He is concerned about the lake bed being too dry and attracting people on all terrain vehicles who enjoy driving around the lake bottom. He is concerned about his property value decreasing if the lake bed is dry. Further, when the lake level is too low, people cannot enjoy water skiing, boating, and fishing on Lake Theresa. Petitioner, Phillip Lott, a Florida native, has also owned and lived on property abutting Lake Theresa since 1995. Mr. Lott has a Ph.D. in plant ecology, and M.P.A. in coastal zone studies, an M.B.A. in international business, and a B.S. in environmental resource management and planning. Mr. Lott has been well acquainted with the water levels on Lake Theresa for many years. Based upon his personal observations of the lake systems in the Deltona area over the years, Mr. Lott has seen levels fluctuate greatly based upon periods of heavy and light rainfall. Mr. Lott is concerned that the District will permit the City to open the weir to let water flow through the system and cause flooding in some areas and low water levels in other areas. He fears that the District will allow the water to flow and upset the environmental balance, but he admits that this ERP application is for a closed system that will not allow the water to flow as he fears. Mr. Lott similarly does not trust the City to comply with and the District to enforce the conditions of the ERP. Petitioners, James E. and Alicia M. Peake, who were represented by Steven L. Spratt at hearing as their qualified representative, live on Lake Louise, which is interconnected with the Lake Theresa basin. The Peakes are concerned that if the level of Lake Louise drops below 21 feet, nine inches, they will not be able to use the boat launch ramps on the lake. Petitioner, Steven L. Spratt, also lives on Lake Louise, and is concerned about the water levels becoming so low that he cannot use the boat launch on the lake. He has lived on the lake since 2000, and remembers when the water level was extremely low. He fears that approval of the ERP in this case will result in low levels of water once again. Petitioner, Gloria Benoit, has live on Lake Theresa for two years. She also enjoys watching recreational activities on the lake, and feels that approval of the ERP will devalue her lakefront property. Ms. Benoit appeared at the first day of the hearing, but offered no testimony on her behalf. J. Christy Wilson, Esquire, appeared prior to the final hearing as counsel of record for Petitioners, Steven E. Larimer, Kathleen Larimer, and Helen Rose Farrow. Neither Ms. Wilson nor any of the three Petitioners she represented appeared at any time during the hearing, filed any pleadings seeking to excuse themselves from appearing at the final hearing, or offered any evidence, testimony, pre- or post- hearing submittals. Petitioner, Gary Jensen, did not appear at hearing, did not file any pleadings or papers seeking to be excused from appearing at the final hearing, and did not offer any evidence, testimony, pre- or post-hearing submittals. Both the City and the District recognize that areas downstream from the project site, such as Stone Island and Sanford, have experienced flooding in the past in time of high amounts of rainfall. The system proposed by the City for this ERP will operate with the overflow structures closed and a brick and mortar plug in the outfall pipe to prevent water flow from Lake Doyle to Lake Bethel. So long as the overflow structures are closed, the system will mimic pre-construction flow patterns, with no increase in volume flowing downstream. The District has considered the environment in its proposed approval of the ERP. The area abutting the project is little urbanized and provides good aquatic and emergent marsh habitat. With the exception of the western shore area of the deepwater marsh ("west marsh area"), the bay swamp and remaining deepwater marsh area have good ecological value. In the 1940's, the west marsh area was incorporated into the drainage system of a poultry farm that occupied the site. This area apparently suffered increased nutrient influxes and sedimentation that contributed to a proliferation of floating mats of aquatic plants and organic debris. These tussocks reduced the deepwater marsh's open water and diminished the historical marsh habitat. Water under the tussocks is typically anoxic owing to total shading by tussocks and reduced water circulation. Thick, soft, anaerobic muck has accumulated under the matted vegetation. Exotic shrubs (primrose willow Ludwigia peruvania) and other plants (cattails Typha spp.) dominate the tussocks. The construction of the project, from the 2003 Emergency Order, resulted in adverse impacts to 1.3 acres of wetlands having moderately high- to high ecological value and 0.2 acres of other surface waters. The 0.2 acre impact to other surface waters was to the lake bottom and the shoreline of Lake Doyle where the weir structure was installed. The 0.3 acres of wetland impacts occurred at the upper end of the deepwater marsh where the pipe was installed. The largest wetland impact (1.0 acre) was to the bay swamp. The bay swamp is a shallow body dominated by low hummocks and pools connected inefficiently by shallow braided channels and one acre is filled with a 1-2 foot layer of sediment following swamp channelization. Disturbance plants (e.g., primrose willow, Ludwigia peruvania, and elderberry Sambucus Canadensis) now colonize the sediment plume. Pursuant to the District's elimination and reduction criteria, the applicant must implement practicable design modifications, which would reduce or eliminate adverse impacts to wetlands and other surface waters. A proposed modification, which is not technically capable of being done, is not economically viable, or which adversely affects public safety through endangerment of lives or property is not considered "practicable." The City reduced and/or eliminated the impacts to the lake bottom and shoreline of Lake Doyle and deepwater marsh, to the extent practicable. The impacts were the minimum necessary to install the weir structure and pipe for the system; the weir structure and pipe were carefully installed on the edges of the wetland and surface water systems, resulting in a minimum amount of grading and disturbance. To compensate for the loss of 1.3 acres of wetlands and 0.2 acres of other surface waters, the City proposes to preserve a total of 27.5 acres of wetlands, bay swamp, marsh, and contiguous uplands. Included in this 27.5 acres are 6.4 acres of the west marsh, which are to be restored. The parties stipulated that the mitigation plan would adequately compensate for losses of ecological function (e.g. wildlife habitat and biodiversity, etc.) resulting from the project. Water quality is a concern for the District. Lake Monroe is included on the Florida Department of Environmental Protection's verified list of impaired water bodies for nitrogen, phosphorous, and dissolved oxygen. Water quality data for Lake Monroe indicate the lake has experienced high levels of nitrogen and phosphorous and low levels of dissolved oxygen. Prior to construction of the project, there was no natural outfall from the Lake Theresa Basin to Lake Monroe and therefore no contribution from this basin to nitrogen and phosphorous loadings to Lake Monroe. Lake Colby, Three Island Lakes (a/k/a Lake Sixma), and the Savannah are surface waters within the Lake Theresa Basin for which minimum levels have been adopted pursuant to Florida Administrative Code Chapter 40C-8. The system will operate with the overflow structures closed and a brick and mortar plug in the outfall pipe to prevent water flow from Lake Doyle to Lake Bethel, resulting in no outfall from the Theresa Basin to Lake Monroe. Minimum flows established for surface waters within the Lake Theresa Basin will not be adversely impacted. Under the first part of the secondary impact test, the City must provide reasonable assurance that the secondary impacts from construction, alteration, and intended or reasonable expected use of the project will not adversely affect the functions of adjacent wetlands or surface waters. The system is designed as a low intensity project. As proposed, little activity and maintenance are expected in the project site area. The reasonably expected use of the system will not cause adverse impacts to the functions of the wetlands and other surface waters. None of the wetland areas adjacent to uplands are used by listed species for nesting or denning. In its pre-construction state, the project area did not cause or contribute to state water quality violations. Under the second part of the secondary impact test, the City must provide reasonable assurance that the construction, alteration, and intended or reasonably expected uses of the system will not adversely affect the ecological value of the uplands to aquatic or wetland dependent species for enabling existing nesting or denning by these species. There are no listed threatened or endangered species within the project site area. Under the third part of the secondary impact test, and as part of the public interest test, the District must consider any other relevant activities that are closely linked and causally related to any proposed dredging or filling which will cause impacts to significant historical and archaeological resources. When making this determination, the District is required, by rule, to consult with the Division of Historical Resources. The Division of Historical Resources indicated that no historical or archaeological resources are likely present on the site. No impacts to significant historical and archaeological resources are expected. Under the fourth part of the secondary impact test, the City must demonstrate that certain additional activities and future phases of a project will not result in adverse impacts to the functions of wetlands or water quality violations. The City has submitted to the District preliminary plans for a future phase in which the system would be modified for the purpose of alleviating high water levels within the Lake Theresa Basin when the level in Lake Doyle rises above an elevation of 24.5 feet. Based upon the plans and calculations submitted, the proposed future phase, without additional measures, could result in minor increases in the loadings of nitrogen and phosphorous to Lake Monroe. Lake Monroe is included on the Florida Department of Environmental Protection's verified list of impaired water bodies due to water quality data indicating the lake has experienced high levels of nitrogen and phosphorous, and low levels of dissolved oxygen. Under this potential future phase, there would be an outfall from the Lake Theresa Basin to Lake Monroe. To address the impact on water quality of this potential future phase, the City has submitted a loading reduction plan for nitrogen, phosphorous, and dissolved oxygen. The plan includes compensating treatment to fully offset the potential increased nutrient loadings to Lake Monroe. Specifically, the loading reduction plan includes: Construction and operation of compensating treatment systems to fully offset anticipated increased nutrient loadings to Lake Monroe. Weekly water quality monitoring of the discharge from Lake Doyle for total phosphorous and total nitrogen. A requirement that the overflow structure be closed if the total phosphorous level reaches 0.18 mg/l or higher or the total nitrogen level reaches 1.2 mg/l or higher in any given week and will remain closed until levels fall below those limits. The implementation of these water quality mitigation measures will result in a net improvement of the water quality in Lake Monroe for nitrogen, phosphorous, or dissolved oxygen. The future phase was conceptually evaluated by the District for impacts to wetland functions. The future phase as proposed could result in adverse impacts to wetland functions. Operation of the system with the overflow structures open could impact the bay swamp and deepwater marsh. The City has demonstrated that any adverse impacts could be offset through mitigation. Based upon the information provided by the City and general engineering principles, the system is capable of functioning as proposed. The City of Deltona will be responsible for the operation, maintenance, and repair of the surface waster management system. A local government is an acceptable operation and maintenance entity under District rules. The public interest test has seven criteria. The public interest test requires the District to evaluate only those parts of the project actually located in, on, or over surface waters or wetlands, to determine whether a factor is positive, neutral, or negative, and then to balance these factors against each other. The seven factors are as follows: the public health, safety, or welfare of others; conservation of fish and wildlife and their habitats; fishing, recreational value, and marine productivity; temporary or permanent nature; 5) navigation, water flow, erosion, and shoaling; 6) the current condition and relative value of functions; and 7) historical and archaeological resources. There are no identified environmental hazards or improvements to public health and safety. The District does not consider impacts to property values. To offset any adverse impacts to fish and wildlife and their habitats, the City has proposed mitigation. The areas of the project in, on, or over wetlands do not provide recreational opportunities. Construction and operation of the project located in, on, or over wetlands will be permanent in nature. Construction and operation of the project located in, on, or over wetlands will not cause shoaling, and does not provide navigational opportunities. The mitigation will offset the relative value of functions performed by areas affected by the proposed project. No historical or archaeological resources are likely on the site of the project. The mitigation of the project is located within the same drainage basin as the project and offsets the adverse impacts. The project is not expected to cause unacceptable cumulative impacts.

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.
Findings Of Fact The parties stipulated, and it is so found, that Petitioner, DER, has jurisdiction over both the issues and the Respondents Dey and KWC. KWC owns and operates a water system which supplies water to both residential and commercial customers in the City of Keystone Heights, Florida. Virginia Key is the President of KWC, a member of the Board of Directors of the corporation, and one of the five stockholders. The other stockholders are her sisters. The five sisters are the daughters of the late G. E Wiggins, and inherited the company from him at his death in 1969. Mr. Wiggins developed the water company in the 1920's and operated it until his death. KWC came under the jurisdiction of the Florida Public Service Commission (PSC) just prior to Mr. Wiggins' death. At that time, pursuant to a PSC requirement, it was assessed and valued at a sum in excess of $250,000.00 by a consultant firm hired for the purpose. As of late November, 1984, KWC served approximately 752 residential customers which, when multiplied by an average 2.5 persons per family factor, results in a total of approximately 1,880 residential inhabitants served by the water system. In addition, the system serves 105 commercial customers. It is impossible to estimate with any reasonable degree of accuracy the number of individuals involved in the commercial service. The system consists of three wells drilled in 1940, 1946, and 1960 to a depth of 350, 450, and 492 feet respectively. Total yield from the three wells is normally 1,350 gallons per minute. The wells are generally well protected against surface water infusion, are normally not subject to inundation, and have had no salt water infiltration problems in the past. At the present time, well number 2, drilled in 1946, with a 350 gpm yield is out of service. The water, when pumped from the ground, is stored in two tanks-one with a 60,000 gallon capacity and the other with a capacity of 800 gallons. Both tanks are steel. Chlorine is added to the water in each storage situation by a hyper-chlori- nation system before the water is sent to the storage tank. The distribution system is made up of 6" and 2" diameter pipe. In March, 1984, two different inspections of the water system, done by, in one case, an environmental specialist and in the other, an Engineer I with DER, revealed several deficiencies in the maintenance and operation of the system all of which constitute violations of DER rules. Specifically, these include (1) failure to provide an auxiliary power source in the event the main pumping capability of the system is lost, (Rule 17-22.106 (3)(a); (2) failure to utilize for the system an operator certi- fied by the state with a Class C license, (Rule 17-22.107(3)(b); (3) failure to maintain a free chlorine residual in the water of at least 0.2 ppm in the system, (Rule 17-22.106(3)(c); (4) failure to maintain a minimum pressure of 20 ppi in the distribution system, (Rule 17-22.106(3)(f); (5) failure to have a gas chlorination facility, (Rule 17-22.106(3)(d); and (6) failure to obtain proper permits to expand the distribution system, (Rule 17-22.108 (1)(b) Rule 17-22, F.A.C., sets up requirements for safe drinking water and was designed to establish guidelines and standards for facilities and water and to bring water into compliance with the Federal Act. Twenty ppi of pressure in the system was adopted as a standard minimum for residual pressure to protect against outside contaminants getting into the water system. Such contaminants could come from ground water, leaks, and water in storage tanks attached to the system such as toilet tanks, being aspirated into the system. Also a certain amount of pressure is required to operate appliances. Normally minimum pressure is found in areas at the edge of the system and in those areas where inadequate chlorination is located. They interact and both pressure and chlorinization are required. Chlorine can be injected into the system generally in two ways: the first is through gas chlori- nation and the second, through hyper-chlorinization as is used in the instant system. The effectiveness of hyper-chlorinization is limited, however, by the size of the system. Basically, hyper- chlorinization is effective when the demand in the system for pressure is no more than 10 ppi. Above this, gas chlorinization is necessary. As late as January 4, 1985, Mr. Dykes went to Keystone Heights to test the system. His tests showed that 11.9 ppi is the average daily flow per 24 hours for the last 12 months. Since this figure is above 10 ppi, in his opinion, a gas chlorinization system would be needed. Chlorine is used to purify water because it has been shown, through long use, to prevent disease. The requirement for a residual chlorine level in water, therefore, is consistent with that concept to insure chlorine is always in the water in sufficient quantity to prevent disease. Respondent's plant has less than the 0.2 residual that is required under the rule. This insufficiency is caused by the inadequate chlorinization system which has insufficient capacity to provide the appropriate amount of chlorine. At the current level, it is providing only approximately 60 percent of the needed chlorine. To correct this deficiency Mr. Dykes recommends installation of a gas chlorinization system. In addition, the pneumatic tank storing the water from the number 3 well does not give sufficient detention time to allow for appropriate reaction of the chlorine contained in the water before the water is released into the distribution system. Another factor relating to the lack of adequate pressure in the system is the fact that, in Mr. Dykes' opinion, too much of the system is made up of 2" diameter water line. A line of this small diameter prevents the maintenance of adequate pressure especially in light of the fact that there are numerous old lines in the system some with corrosion and scale in them which tends to reduce pressure. This latter factor would be prevalent even in the 6" lines. The current plant manager, Mr. Cross, who has been with Respondent for approximately 4 years is, with the exception of one part time employee, the only operations individual associated with the plant. As such, he repairs the meters and the lines, checks the pumps, the chlorinator, and checks and refills the chlorine reservoir on a seven day a week basis. Be learned the operation of the plant from his precedessor, Mr. Johnson, an unlicensed operator who was with the company for 10 years. Mr. Cross has a "D" license which he secured last year after being notified by DER that a license was required. It was necessary for him to get the "D" license before getting the required "C" license. At the present time, he is enrolled to take courses leading toward the "C" license. At the present time, however, he is not, nor is anyone else associated with KWC, holding a license as required. The rule regarding auxiliary power provides that all community systems serving 350 or more persons shall have standby pumping capability or auxiliary power to allow operation of the water treatment unit and pumping capability of approximately one-half the maximum daily system demand. Respondent has admitted that the system is not equipped with an auxiliary power source and it has already been established that more than 350 persons are served by the system. Respondent also admits that subsequent to November 9, 1977, it constructed main water lines for the system which required the obtaining of a permit from either the Petitioner or the county health unit. Respondent admits that it did not obtain or possess a permit to do the additional construction referenced above from either DER or the Clay County Health Department prior to the construction of the water lines referenced. The inspections referenced above, which identified the problems discussed herein, were accomplished by employees of Petitioner, DER, at a stipulated cost of $898.10. Respondent contends, and there is no evidence to the contrary, that there have been no complaints of contaminated water and that the monthly water samples which Mr. Cross forwards to the Clay County Health Department have been satisfactory. Mr. Cross also indicates that a September, 1983 DER analysis of water samples taken from the system was satisfactory. However, bacteriological analysis reports on water collected from Respondent's system on July 11 and 27, 1983, reflect unsatisfactory levels of either coliform or non-coliform bacteria in the water requiring resubmission of test samples. Respondent also contends that no one has ever gotten sick or died from the water furnished by the system and there is, in fact, no evidence to show this is not true. Even though so far as is known, no one has ever been made sick from the water in the system, in Mr. Dykes' opinion, the risk is there. As a result of the defects identified in this system, insufficient chlorine is going into the system to meet reasonable health standards. Though this does not mean that the water is now bad, it does mean that at any time, given a leak or the infusion of some contaminant, the water could become bad quickly, and the standard established by rule is preventive, designed to insure that even in the case of contamination, the water will remain safe and potable. Respondent does not deny that it is and has been in violation of the rules as set out by the Petitioner. It claims, however, that it does not have sufficient funds available to comply with the rules as promulgated by DER. Respondent has recently filed a request for variance under Section 403.854, Florida Statutes, setting forth as the basis for its request that it does not have the present financial ability to comply with any of the suggested or recommended corrective actions to bring its operation into compliance with the rules. Mr. Protheroe, the consulting engineer who testified for Respondent has not evaluated the system personally. His familiarity with it is a result of his perusal of the records of the company and the Petitioner. Based on his limited familiarity with the system, he cannot say with any certainty if it can be brought into compliance with, for example, the 20 ppi requirement. There are too many unknowns. If, however, the central system was found to be in, reasonably good shape, in his opinion, it would take in excess of $100,000.00 to bring it within pressure standards. To do so would require replacement of the 2" lines, looping the lines, and cleaning and replacing some central system lines as well. In his opinion, it would take three months to do a complete and competent analysis of the system's repair needs. Once that was done, he feels it would take an additional three months to bring the plant into compliance with DER requirements. Other repairs, such as those to the lines outside the plant, would take longer because some are located in the downtown area and have interfaced with other utilities. This could take from three to four months if the money were available to start immediately. Here, however, it has been shown that it is not. Consequently, to do the study and then, if possible, procure the funds required, could take well in excess of six months or so. Mr. Protheroe contends, and there is little if any evidence to indicate to the contrary, that to replace the current system with a new one entirely as it is currently constituted would cost at least $250,000.00. However, in his opinion, no one would ever put in a new system similar to the one currently there. He cannot say how much it would cost to buy the system and make the necessary corrections to it to rectify the deficiencies. His familiarity with the system is not sufficiently complete to do this. He cannot say exactly how much the system is worth in its current state, but he is satisfied that it is worth more than $65,000.00. In that regard, Mrs. Dey indicated that in her opinion, the fair market value of the system is currently at $250,000.00. At the present time, there are current outstanding loans in excess of $9,000.00 at 16 percent interest. This current loan basis has been reduced from a higher figure. In 1977, the company borrowed $15,000.00 at 9 percent. In 1981, it borrowed $5,000.00 more at 18 percent. In 1982, the loans were consolidated at an increased rate of 16 percent and the officers have been advised by their current creditors that they cannot borrow any more money for the system in its current state. They would sell the system if a reasonable price could be realized. However, any inquiries on prospective purchases have been chilled by a low rate base assigned by the PSC. In that regard, the City of Keystone Heights offered to purchase the system for $59,000.00. This offer was declined as being unreasonable. Nonetheless, in light of the low rate base assigned by the PSC in its order issued on December 21, 1981 of slightly over $53,000.00 the offer by the city of $59,000.00 is not completely out of line. A certified public accountant, in KWC's December 31, 1983 financial report assigned a valuation of approximately $62,000.00, again a figure only slightly higher than that offered by the city, but substantially less than the $175,000.00 price asked of the city by Respondent Dey and her sisters. Mrs. Dey indicated that to the best of her knowledge the PSC denied rate increases for the purposes of improvements. In the presentation before the commission, respondents relied exclusively on the services of their attorney and accountant. Evidence from Mr. Lowe, of the PSC, however, indicates that KWC has never requested a rate increase to finance any of the improvements called for here. In the PSC order referred to above, Respondent was awarded a 12.25 percent rate of return on its rate base. This figure was an amalgam of a more than 13 percent rate on equity and a lesser figure for cost of doing business, including debt. At the time of that hearing, however, the debt cost was based on a 9 percent interest figure. The 16 percent interest figure came afterwards and no hearing has been requested based on the higher interest rate and it is so found.
Recommendation Based on the foregoing findings of fact and conclusion of law, it is, therefore: RECOMMENDED that Respondents Virginia W. Day and the Keystone Water Company be ordered to comply with the Orders for Corrective Action previously filed herein to bring the water system in question in compliance with the Florida Safe Water Drinking Act without delay or suffer the penalties for non- compliance called for by statute and, in addition, pay costs of investigation in the amount of $898.16. RECOMMENDED in Tallahassee, Florida this 19th day of February, 1985. ARNOLD H. POLLOCK Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 19th day of February, 1987. COPIES FURNISHED: Debra A. Swim, Esquire Assistant General Counsel Twin Towers Office Building 2600 Blair Stone Road Tallahassee, Florida 32301 John E Norris, Esquire 10 North Columbia Street Lake City, Florida 32055 Victoria Tschinkel, Secretary Department of Environmental Regulation 2600 Blair Stone Road Tallahassee, Florida 32301
The Issue The issue to be determined in this case is whether Respondents, United States Sugar Corporation (“USSC”), Sugar Farms Co-op (“SFC”), and Sugar Cane Growers Cooperative of Florida (“SCGC”) (collectively “the Applicants”) are entitled to the Everglades Works of the District permits (“WOD Permits”), issued to them by the South Florida Water Management District (“District”).
Findings Of Fact The Parties Audubon is a not-for-profit organization dedicated to restoring and conserving natural ecosystems, focusing on birds and their habitats. Audubon has a substantial interest in the protection of the Everglades and other ecosystems in the area. Audubon’s interest is affected by the proposed agency action because the WOD Permits authorize agricultural discharges that affect these ecosystems. The District is a Florida public corporation with the authority and duty to administer regulatory programs in chapter 373, and Florida Administrative Code Title 40E, including a program for regulating discharges from the Everglades Agricultural Area (“EAA”) into works of the District. The EAA is located south of Lake Okeechobee and comprises about 570,000 acres. The majority of EAA agriculture is sugarcane, with some row crops, such as radishes, leafy vegetables, and corn, and turf sod. During fallow periods, rice is also grown. The Applicants are owners and lessees of agricultural lands in the EAA. Background Some essential background for this case is set forth in rule 40E-63.011: The Everglades is a unique national resource. It has a high diversity of species, and provides habitat for large populations of wading birds and several threatened and endangered species, including wood storks, snail kites, bald eagles, Florida panthers, and American crocodiles. Large portions of the northern and eastern Everglades have been drained and converted to agricultural or urban land uses. Only 50% of the original Everglades ecosystem remains today. The remainder is the largest and most important freshwater sub-tropical peatland in North America. The remaining components of the historic Everglades are located in the Water Conservation Areas (WCAs) and Everglades National Park (ENP). ENP and Loxahatchee National Wildlife Refuge (WCA 1) are Outstanding Florida Waters, a designation which requires special protection for the resource. Large portions of the Everglades ecosystem have evolved in response to low ambient concentrations of nutrients and seasonal fluctuations of water levels. Prior to creation of the Everglades Agricultural Area (EAA), nitrogen and phosphorus were mainly supplied to large areas only in rainfall. Phosphorus is the primary limiting nutrient throughout the remaining Everglades. Sawgrass has lower phosphorus requirements than other species of Everglades vegetation. A substantial portion of EAA nutrients is transported to the remaining Everglades either in dissolved or in particulate form in surface waters. The introduction of phosphorus from EAA drainage water has resulted in ecological changes in substantial areas of Everglades marsh. These changes are cultural eutrophication, which is an increase in the supply of nutrients available in the marsh. The increased supply of phosphorus in Everglades marshes has resulted in documented impacts in several trophic levels, including microbial, periphyton, and macrophyte. The areal extent of these impacts is increasing. In 1988, the United States sued the District and the Florida Department of Environmental Regulation, now the Department of Environmental Protection (“DEP”), in federal court, alleging that the agencies failed to enforce Florida’s water quality standard for nutrients in waters of Loxahatchee Wildlife Refuge and Everglades National Park. The principal pollutant of concern was phosphorus. Audubon, USSC, and certain members of SCGC and SFC intervened in the federal case. In February 1992, the parties resolved their dispute through a settlement agreement approved by the federal court (“the Consent Decree”). The Consent Decree required the District and DEP to take action to meet water quality standards by December 31, 2002. At that time, the nutrient water quality standard was a narrative standard, prohibiting the discharge of nutrients so as to cause “an imbalance in natural populations of aquatic flora and fauna.” The Consent Decree directed the District to construct 34,700 acres of stormwater treatment areas (“STAs”) so that nutrient-laden surface water discharged from the EAA could be treated before discharge to the Everglades Protection Area (“EvPA”), which includes Loxahatchee Wildlife Refuge, Everglades National Park, and the Water Conservation Areas. STAs are large freshwater wetlands which remove phosphorus from the water column through physical, chemical, and biological processes such as sedimentation, precipitation, plant growth, and microbial activity. The first STAs were constructed and in operation in 1993. The Applicants operate in the S-5A Basin within the EAA. Their surface water is conveyed to STA-1W for treatment before being discharged to the EvPA. The Consent Decree required the District to initiate a regulatory program by 1992 to require permits for discharges from internal drainage systems (farms) in the EAA. The regulatory program was to be based on agricultural best management practices (“BMPs”). The goal of the program, as stated in the Consent Decree, was to reduce phosphorus loads from the EAA by 25 percent over the base period (1979-1988). In 1992, the District promulgated rule chapter 40E-63, which required EAA farmers to obtain WOD permits and to implement agricultural BMP plans. The BMP plans address fertilizer use and water management. Permittees must also implement a water quality monitoring plan. The rules require reduction of the total phosphorus loads discharged from the EAA Basin, as a whole, by 25 percent from historic levels. See Fla. Admin. Code R. 40E-63.101. If the EAA, as a whole, is in compliance, individual permittees are not required to make changes to their operations. See Fla. Admin. Code R. 40E-63.145(3)(d). If the 25 percent reduction requirement is not met, the rule contemplates that individual permittees in the EAA would have to reduce nutrient loads in their discharges. See Fla. Admin. Code R. 40E-63.145(3)(e).1/ The Consent Decree also required the District to obtain permits from the Department for discharges from the STAs to the EvPA and to conduct research and adopt rules to “numerically interpret” the narrative standard. In 1994, the Florida Legislature enacted the Everglades Forever Act (“the Act”), chapter 94-115, Laws of Florida, which is codified in section 373.4592. The Legislature authorized the district to proceed expeditiously with implementation of the Everglades Program. See § 373.4592(1)(b), Fla. Stat. The “Everglades Program” means the program of projects, regulations, and research described in the Act, including the Everglades Construction Project. The Everglades Construction Project involved the construction of 40,452 acres of STAs, which is 5,350 acres more than was required by the federal Consent Decree. The Act acknowledged the BMP regulatory program for the EAA that the District had established in rule chapter 40E-63, and stated: Prior to the expiration of existing permits, and during each 5-year term of subsequent permits as provided for in this section, those rules shall be amended to implement a comprehensive program of research, testing, and implementation of BMPs that will address all water quality standards within the EAA and Everglades protection Area. See § 373.4592(4)(f)2., Fla. Stat. The Act required DEP to issue permits to the District to construct, operate, and maintain the STAs. See § 373.4592(9)(e), Fla. Stat. The Act required development of a numeric water quality phosphorus standard for the EvPA by 2003. See § 373.4592(4)(e), Fla. Stat. The Act set the goal of achieving the phosphorus standard in all parts of the EvPA by December 31, 2006. In June 1995, modifications were made to the Consent Decree. The deadline for achieving water quality standards in the EvPA was changed from December 31, 2002, to December 31, 2006. The STAs were increased from 34,700 acres to 40,452 acres. The chronological developments outlined above indicate the intent of the Legislature and the parties to the Consent Decree to conform state law and the Consent Decree to each other. In 2001, DEP initiated rulemaking that lead to its adoption of the Phosphorus Rule, rule 62-302.540, in 2003. The rule set a numeric phosphorus criterion for the EvPA of 10 parts per billion (“ppb”), applied through a four-part test in which attainment is determined separately for “unimpacted” and “impacted areas” of the EvPA. See Fla. Admin Code R. 62- 302.540(4). In conjunction with this rulemaking, the DEP and District developed the Everglades Protection Area Tributary Basins Long Term Plan for Achieving Water Quality Goals (“Long- Term Plan”) in March 2003. The Long-Term Plan provided remedial measures and strategies divided into pre-2006 projects and post- 2006 projects. The pre-2006 projects included structural and operational modifications to the existing STAs, implementation of agricultural and urban BMPs in areas outside the EAA or C-139 basins, and construction of several restoration projects congressionally mandated by the Comprehensive Everglades Restoration Plan. Modeling of treatment capabilities of the STAs after implementation of the pre-2006 projects predicted that the 10 ppb standard for phosphorus could be achieved, but not consistently. Therefore, the Long-Term Plan required the District to identify and evaluate methods to improve phosphorus reductions, and if the phosphorus criterion was not achieved by December 31, 2006, to implement post-2006 modifications and improvements. The post- 2006 strategies include projects to expand and improve the STAs. They do not include changes to the BMP program. In 2003, the Legislature substantially amended the Act. It incorporated the Long-Term Plan into the Act, finding that it “provides the best available phosphorus reduction technology based on a combination of the BMPs and STAs.” § 373.4592(3)(b), Fla. Stat. The Long-Term Plan contemplates maintenance of the BMP program in the EAA, with refinements derived from BMP research. Recent Conditions and Events As previously stated, chapter 40E-63 requires the total phosphorus load from the EAA to be reduced by not less than 25 percent from historic levels. Since full implementation of the BMP regulatory program, annual phosphorus loads have been reduced by approximately 50 percent. Despite the efforts and projects undertaken, the phosphorus standard was not being achieved as of December 31, 2006, in all parts of the EvPA. In 2007, the DEP issued a permit to the District for discharges from the STAs to the EvPA (referred to as the “Everglades Forever Act” or “EFA permit”). The permit required the District to design and construct several regional water management projects, including structural enhancements to STA-1W, and the construction of 6,800 acres of additional STAs. The permit and its compliance schedules provided interim relief through 2016 from the water quality based effluent limitation (WQBEL) necessary to achieve the 10 ppb phosphorus standard. The 2007 EFA permit was not challenged by Audubon or any other entity. The District, DEP, and the United States Environmental Protection Agency began working together in 2010 to develop new strategies for achieving compliance with the phosphorus standard in the EvPA. The agencies determined that compliance could be achieved by expanding the STAs by 7,300 acres (6,500 acres would be added to STA-1W) and constructing flow equalization basins to store up to 110,000 acre feet of stormwater runoff. These basins are designed to attenuate peak flows into the STAs in order to improve the processes that remove phosphorus. In September 2012, DEP issued the District a new EFA permit, which authorized continued operation of the District’s S-5A pump station, STA-1W, and the related conveyance systems by which stormwater runoff from the S-5A Basin is ultimately discharged to the EvPA. The permit was issued with a Consent Order, requiring the District to expand STA-1W by 6,500 acres of effective treatment area in accordance with a timeline and the District’s Restoration Strategies. The 2012 EFA Permit and Consent Order were not challenged by Audubon or any other entity. In 2013, the Legislature amended the Act again. The Act’s reference to the Long-Term Plan was revised to include the District’s Restoration Strategies Regional Water Quality Plan, which called for expanding the STAs and constructing flow equalization basins. See § 373.4592(2)(j), Fla. Stat. The Legislature added a finding that “implementation of BMPs, funded by the owners and users of land in the EAA, effectively reduces nutrients in waters flowing into the Everglades Protection Area.” See § 373.4592(1)(g), Fla. Stat. The 2013 amendments indicated the Legislature’s intent to codify into law the strategies developed by the District and other regulatory agencies to achieve water quality standards in the EvPA. Those strategies do not materially change the BMP program in the EAA. The Act and the rules of the District create programs for achieving restoration of the EvPA that rely heavily on the STAs. Over the years, the STAs have repeatedly been enlarged and enhanced. In contrast, the requirement for farmers in the EAA to reduce their phosphorus loading by 25 percent has not changed in 21 years. It is beyond the scope of this proceeding to question the wisdom of the programs that have been established by statute and rule. Whether Additional Water Quality Measures Are Required A principal dispute in this case is whether the WOD Permits must include additional water quality measures to be implemented by the Applicants. Section 373.4592(4)(f)4. provides that, as of December 31, 2006, all EAA permits shall include “additional water quality measures, taking into account the water quality treatment actually provided by the STAs and the effectiveness of the BMPs.” Audubon asserts that the requirement for additional water quality measures has been triggered. The District does not interpret the statute as requiring additional water quality measures under current circumstances. The interpretation of the statute is primarily a disputed issue of law and is addressed in the Conclusions of Law. There, it is concluded that additional water quality measures are not required. Whether the BMP Plans are Adequate Audubon contends that the WOD Permits should be denied because the Applicant’s existing BMP plans are not “tailored” to particular soils, crops, and other conditions. This contention is based on section 373.4592(4)(f)2.c., which states in relevant part: BMPs as required for varying crops and soil types shall be included in permit conditions in the 5-year permits issued pursuant to this section. Audubon showed that the Applicants have similar BMP plans for the thousands of acres covered in the three WOD Permits, and contends that this similarity proves that BMPs are not being tailored to specific farm conditions. However, soils and crops are similar throughout the EAA. The soils of the EAA are almost entirely muck soils and the primary crop is sugarcane with some corn or other vegetable rotated in. The Applicants use many of the same BMPs because they have similar soils and grow similar crops. There are three main categories of BMPs implemented in the EAA: nutrient and sediment control BMPs, particulate matter and sediment control BMPs, and water management BMPs. See Fla. Admin. Code R. 40E-63.136, Appendix A2. The BMPs proposed by the Applicants are based on research in the EAA and recommendations specifically for EAA soils and the crops grown there. The Applications do not identify the specific BMPs that will be implemented, but only the number of BMPs that will be selected from each of the BMP categories (i.e., sediment control). The Applicants must use BMPs on the District’s list of approved BMPs unless an alternative BMP is requested and approved. The lack of greater detail was explained as necessitated by the need for flexibility during the life of the permit to adapt BMPs to varied crops and conditions. Audubon does not believe the BMP plans are tailored enough, but there is no rule criterion for determining how tailored BMP plans must be, except they must achieve the overall goal of reducing phosphorus loading in discharges from the EAA by at least 25 percent. This goal is being achieved.2/ Audubon did not show that any particular BMP being used by an Applicant was the wrong BMP for a particular soil and crop, or identify the BMP that Audubon believes should be used. Audubon failed to prove that the Applicants’ BMP plans do not meet applicable requirements. Whether the Applications Are Complete Audubon contends that the WOD Permits must be denied because the Applications are incomplete. Many of Audubon’s completeness issues deal with minor discrepancies of a type that are more appropriately resolved between the District and applicants, not violations of criteria that are likely to affect a third party’s interest in environmental protection. Rule 40E-63.130 lists the requirements for a permit application for activities in the EAA Basin. An Application Guidebook is incorporated into chapter 40E-63, which contains instructions for completing the application. For applications to renew a permit, the practice of the District is to not require the resubmittal of information that was previously submitted to the District and which has not changed. The Application Guidebook explains this practice. The Applicants supplemented their applications at the final hearing to provide information that Audubon claimed was omitted from the Applications.3/ Audubon contends that the Applications are incomplete because some application forms are not dated and other forms are not signed by appropriate entities. The District explained its rule interpretation and practices associated with the forms. Additional signatures and dates were submitted at the final hearing. Audubon failed to demonstrate that the Applications are incomplete based on the identity of the persons who signed application forms or the lack of dates. Audubon contends the Applications are incomplete because copies of contracts or agreements are not included as required by rule 40E-63.132(3). Audubon failed to prove that contracts and agreements exist that were not included. Audubon contends the Applications are incomplete because they do not contain a completed Form 0779, entitled “Application For A Works Of The District Permit,” as required by rule 40E-63.132(5). In some cases, the information for Form 0779 had been previously submitted and was unchanged, so the District did not require it to be resubmitted for the permit renewal. Additional information was provided at the final hearing. Audubon failed to prove that the Applications are incomplete based on missing information on Form 0779. Audubon contends that the Applications are incomplete because documentation regarding leased parcels was missing. Pursuant to rule 40E-63.130(1)(a), individual permit applications must be submitted by the owner of the land on which a structure is located and any entity responsible for operating the structure, and the permit application must include the owners of all parcels which discharge water tributary to the structure. Applications may be submitted by a lessee if the lessee has the legal and financial capability of implementing the BMP Plan and other permit conditions. The District explained that when applications are submitted by a lessee who will be the permittee or co-permittee, the District requires the lessee to be a responsible party for the entire term of the permit, which is five years. If the lessee is a not a co-permittee, the District does not require information about the lease and does not require the lessee’s signature. If the lessee is a co-permittee, but the lease expires during the term of the permit, the District requires the applicant to modify the permit when the lease expires. Audubon failed to prove that the Applications are incomplete based on lease information Audubon contends that the Applications are incomplete because they fail to show that the Applicants participated in an education and training program as required by rule 40E- 63.136(1)(g). The preponderance of the evidence shows that the Applicants participated in education and training programs. Audubon failed to prove that the Applications are incomplete for any of the reasons raised in its petition for hearing or advanced at the final hearing. Water Quality Standards in the EAA Audubon presented some evidence of algal accumulations in ditches and canals, but the evidence was insufficient to prove the Applicants are violating water quality standards applicable in the EAA. Summary Audubon failed to carry its burden to prove that the Applicants are not entitled to the WOD Permits.
Recommendation Based on the foregoing Findings of Facts and Conclusions of Law, it is RECOMMENDED that South Florida Water Management District issue Permit Nos. 50-00031-E, 50-00018-E, and 50-00047-E. DONE AND ENTERED this 10th day of February, 2014, 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 10th day of February, 2014.
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. "Clean techniques" shall mean those applicable field sampling procedures and analytical methods referenced in "Method 1669: Sampling Ambient Water for Trace Metals at EPA Water Quality Criteria Levels, July 1996, USEPA.

"Designated use" shall mean the present and future most beneficial use of a body of water as designated by the Environmental Regulation Commission by means of the classification system contained in Chapter 62-302, F.A.C. "Estuary" shall mean predominantly marine regions of interaction between rivers and nearshore ocean waters, where tidal action and river flow mix fresh and salt water. Such areas include bays, mouths of rivers, and lagoons. "Impaired water" shall mean a water body or water body segment that does not meet its applicable water quality standards as set forth in Chapters 62-302 and 62-4 F.A.C., as determined by the methodology in Part III of this chapter, due in whole or in part to discharges of pollutants from point or nonpoint sources. "Lake Condition Index" shall mean the benthic macroinvertebrate component of a bioassessment conducted following the procedures outlined in "Development of Lake Condition Indexes (LCI) for Florida," Florida Department of Environmental Protection, July, 2000, which is incorporated by reference. "Natural background" shall mean the condition of waters in the absence of man- induced alterations based on the best scientific information available to the Department. The establishment of natural background for an altered waterbody may be based upon a similar unaltered waterbody or on historical pre-alteration data. "Nuisance species" shall mean 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. "Physical alterations" shall mean human-induced changes to the physical structure of the water body. "Planning list" shall mean the list of surface waters or segments for which assessments will be conducted to evaluate whether the water is impaired and a TMDL is needed, as provided in subsection 403.067(2), F.S. "Pollutant" shall be as defined in subsection 502(6) of the CWA. Characteristics of a discharge, including dissolved oxygen, pH, or temperature, shall also be defined as pollutants if they result or may result in the potentially harmful alteration of downstream waters.

"Secretary" shall mean the Secretary of the Florida Department of Environmental Protection. "Spill" shall mean a short-term, unpermitted discharge to surface waters, not to include sanitary sewer overflows or chronic discharges from leaking wastewater collection systems. "Stream" shall mean a free-flowing, predominantly fresh surface water in a defined channel, and includes rivers, creeks, branches, canals, freshwater sloughs, and other similar water bodies. "Stream Condition Index" shall mean a bioassessment conducted following the procedures outlined in "Development of the Stream Condition Index (SCI) for Florida," Florida Department of Environmental Protection, May, 1996, which is incorporated by reference. "Surface water" means those waters of the State upon the surface of the earth to their landward extent, whether contained in bounds created naturally or artificially or diffused. Water from natural springs shall be classified as surface water when it exits from the spring onto the earth's surface. "Total maximum daily load" (TMDL) for an impaired water body or water body segment shall mean the sum of the individual wasteload allocations for point sources and the load allocations for nonpoint sources and natural background. Prior to determining individual wasteload allocations and load allocations, the maximum amount of a pollutant that a water body or water segment can assimilate from all sources without exceeding water quality standards must first be calculated. A TMDL shall include either an implicit or explicit margin of safety and a consideration of seasonal variations. "Verified list" shall mean the list of impaired water bodies or segments for which TMDLs will be calculated, as provided in subsection 403.067(4), F.S., and which will be submitted to EPA pursuant to paragraph 303(d)(1) of the CWA. "Water quality criteria" shall mean elements of State water quality standards, expressed as constituent concentrations, levels, or narrative statements, representing a quality of water that supports the present and future most beneficial uses. "Water quality standards" shall mean standards composed of designated present and future most beneficial uses (classification of waters), the numerical and narrative criteria applied to the specific water uses or classification, the Florida antidegradation policy, and the moderating provisions (mixing zones, site-specific alternative criteria, and exemptions) contained in Chapter 62-302, F.A.C., and in Chapter 62-4, F.A.C., adopted pursuant to Chapter 403, F.S. "Water segment" shall mean a portion of a water body that the Department will assess and evaluate for purposes of determining whether a TMDL will be required. Water segments previously evaluated as part of the Department's 1998 305(b) Report are depicted in the map titled "Water Segments of Florida," 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.

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.

The Issue The issue in this matter is whether Respondent, Polk County Board of Commissioners (Polk County or County) has provided Respondent, Southwest Florida Water Management District (SWFWMD), with reasonable assurances that the activities Polk County proposed to conduct pursuant to Standard General Environmental Resource Permit (ERP) No. 4419803.000 (the Permit) meet the conditions for issuance of permits established in Rules 40D-4.301, and 40D-40.302, Florida Administrative Code. (All rule citations are to the current Florida Administrative Code.)
Findings Of Fact Events Preceding Submittal of ERP Application The Eagle-Millsite-Hancock drainage system dates back to at least the 1920's, and has been altered and modified over time, especially as a result of phosphate mining activities which occurred on OFP property in the 1950's-1960's. The system is on private property and is not owned and was not constructed by the County. Prior to 1996, the Eagle-Millsite-Hancock drainage system was in extremely poor repair and not well- maintained. The Eagle-Millsite-Hancock drainage system originates at Eagle Lake, which is an approximately 641-acre natural lake, and discharges through a ditch drainage system to Lake Millsite, which is an approximately 130-acre natural lake. Lake Millsite drains through a series of ditches, wetlands, and ponds and flows through OFP property through a series of reclaimed phosphate pits, ditches and wetlands and ultimately flows into Lake Hancock, which is an approximately 4500-acre lake that forms part of the headwaters for the Peace River. The drainage route is approximately 0.5 to 1 mile in overall length. The Eagle-Millsite-Hancock drainage system is one of eight regional systems in the County for which the County and SWFWMD have agreed to share certain funding responsibilities pursuant to a 1996 letter agreement. To implement improvements to these drainage systems, Polk County would be required to comply with all permitting requirements of SWFWMD. During the winter of 1997-1998, Polk County experienced extremely heavy rainfall, over 39 inches, as a result of El Nino weather conditions. This unprecedented rainfall was preceded by high rainfalls during the 1995-1996 rainy season which saturated surface waters and groundwater levels. During 1998, Polk County declared a state of emergency and was declared a federal disaster area qualifying for FEMA assistance. Along the Lake Eagle and Millsite Lake drainage areas, septic tanks were malfunctioning, wells were inundated and roads were underwater. The County received many flooding complaints from citizens in the area. As a result of flooding conditions, emergency measures were taken by the County. The County obtained SWFWMD authorization to undertake ditch cleaning or vegetative control for several drainage ditch systems in the County, including the Eagle-Millsite-Hancock drainage system. No SWFWMD ERP permit was required or obtained for this ditch cleaning and vegetative control. During its efforts to alleviate flooding and undertake emergency ditch maintenance along the Eagle-Millsite-Hancock drainage route, the County discovered a driveway culvert near Spirit Lake Road which was crushed and impeding flow. The evidence was unclear and contradictory as to the size of the culvert. Petitioner's evidence suggested that it consisted of a 24-inch pipe while evidence presented by the County and by SWFWMD suggested that it was a 56-inch by 36-inch arched pipe culvert. It is found that the latter evidence was more persuasive. On February 25, 1998, the County removed the crushed arched pipe culvert at Spirit Lake Road and replaced it with two 48-inch diameter pipes to allow water to flow through the system. The replacement of this structure did not constitute ditch maintenance, and it required a SWFWMD ERP. However, no ERP was obtained at that time (although SWFWMD was notified prior to the activity). (One of the eight specific construction items to be authorized under the subject ERP is the replacement of this culvert.) Old Florida Plantation, Ltd. (OFP) property also experienced flooding during February 1998. OFP's property is situated along the eastern shore of Lake Hancock, and the Eagle- Millsite-Hancock drainage system historically has flowed across the property before entering Lake Hancock. In the 1950's and 1960's, the property was mined for phosphate. The mining process destroyed the natural vegetation and drastically altered the soils and topography, resulting in the formation of areas of unnaturally high elevations and unnaturally deep pits that filled with water. OFP purchased the property from U.S. Steel in 1991. The next year OFP initiated reclamation of the property, which proceeded through approximately 1998. In 1996, OFP applied to the County for approval of a development of regional impact (DRI). OFP blamed the flooding on its property in 1998 on the County's activities upstream, claiming that the property had never flooded before. But upon investigation, the County discovered a 48-inch diameter pipe on OFP property which, while part of OFP's permitted drainage system, had been blocked (actually, never unopened) due to OFP's concerns that opening the pipe would wash away wetlands plants recently planted as part of OFP's wetland restoration efforts. With OFP and SWFWMD approval, the County opened this pipe in a controlled manner to allow flowage without damaging the new wetlands plants. Following the opening of this blocked pipe, OFP property upstream experienced a gradual drop in flood water levels. When the water level on OFP's property stabilized, it was five feet lower and no longer flooded. Nonetheless, OFP continues to maintain not only that the County's activities upstream caused flooding on OFP property but also that they changed historic flow conditions. This contention is rejected as not being supported by the evidence. Not only did flooding cease after the 48-inch pipe on OFP's property was opened, subsequent modeling of water flows also demonstrated that the County's replacement of the crushed box culvert at the driveway on Spirit Lake Road as described in Finding 8, supra, did not increase flood stages by the time the water flows into the OFP site and did not cause flooding on OFP property in 1998. (To the contrary, OFP actions to block flows onto its property may have contributed to flooding upstream.) On October 6, 1998, the County entered into a contract with BCI Engineers and Scientists to initiate a study on the Eagle-Millsite-Hancock drainage system, identify options for alleviating flooding along the system and prepare an application for an ERP to authorize needed improvements to the system. Prior to the County's submittal of an ERP application, SWFWMD issued a conceptual ERP to OFP for its proposed wet detention surface water management system to support its proposed DRI on the OFP property. OFP's conceptual permit incorporated the Eagle-Millsite-Hancock drainage system and accommodated off-site flowage into the system. Before submitting an ERP application to SWFWMD, the County had communications with representatives of OFP concerning an easement for the flow of the drainage system through OFP property. In March 1999, the County reached an understanding with OFP's engineering consultant whereby OFP would provide the County with an easement across OFP lands to allow water to flow through to Lake Hancock. In turn, the County would: construct and pay for a control structure and pipe east of OFP to provide adequate flowage without adversely affecting either upstream or downstream surface waters; construct and upgrade any pipes and structures needed to convey water across OFP property to Lake Hancock; and provide all modeling data for OFP's review. The ERP Application Following completion of the engineering study, the County submitted ERP Application No. 4419803.000 for a Standard General ERP to construct improvements to the Eagle-Millsite- Hancock drainage system on August 18, 1999. Eight specific construction activities are proposed under the County's project, at various points along the Eagle- Millsite-Hancock drainage system as follows: 1) Add riprap along channel bottom; 2) Modify culvert by replacing 56-inch by 36- inch arch pipe by two 48-inch pipes (after-the-fact, done in 1998, as described in Finding 8, supra); 3) Add riprap along channel bottom; 4) Add box, modify culvert by replacing existing pipe with two 48-inch pipes, add riprap along channel bottom; 5) add riprap along channel bottom; 6) Add weir, modify culvert by replacing existing 24-inch pipe with two 48-inch pipes, add riprap along channel bottom; 7) Add box and modify culvert by replacing existing 24-inch pipe with two 48-inch pipes; 8) Modify existing weir. Under the County's application, construction activities Nos. 6, 7, and 8 would occur on OFP property. In addition, it was proposed that surface water would flow across OFP's property (generally, following existing on-site drainage patterns), and it was indicated that flood elevations would rise in some locations on OFP's property as a result of the improvements proposed in the County's application. (Most if not all of the rise in water level would be contained within the relatively steep banks of the lakes on OFP's property--the reclaimed phosphate mine pits.) In its application, the County stated that it was in the process of obtaining easements for project area. As part of the ERP application review process, SWFWMD staff requested, by letter dated September 17, 1999, that the County clarify the location of the necessary rights-of-way and drainage easements for the drainage improvements and provide authorization from OFP as property owner accepting the peak stage increases anticipated in certain OFP lakes as a result of the County's proposed project activities. On September 28, 1999, OFP obtained a DRI development order (DO) from the County. In pertinent part, the DRI DO required that OFP not adversely affect historical flow of surface water entering the property from off-site sources. Historical flow was to be determined in a study commissioned by the County and SWFWMD. The DO appeared to provide that the study was to be reviewed by OFP and the County and approved by SWFWMD. Based on the study, a control structure and pipe was to be constructed, operated and maintained by the County at the upstream side of the property that would limit the quantity of off-site historical flow, unless otherwise approved by OFP. OFP was to provide the County with a drainage easement for this control structure and pipe, as well as a flowage easement from this structure, through OFP property, to an outfall into Lake Hancock. The DO specified that the flowage easement was to be for quantitative purposes only and not to provide water quality treatment for off-site flows. The DO required OFP to grant a defined, temporary easement prior to first plat approval. In its November 11, 1999, response to SWFWMD's request for additional information, the County indicated it would obtain drainage easements and that it was seeking written acknowledgment from OFP accepting the proposed increases in lake stages. During the ERP application review process, the County continued efforts to obtain flowage easements or control over the proposed project area and OFP's acknowledgment and acceptance of the increase in lake stages. At OFP's invitation, the County drafted a proposed cross-flow easement. But before a binding agreement could be executed, a dispute arose between OFP and the County concerning other aspects of OFP's development plans, and OFP refused to enter into an agreement on the cross- flow easement unless all other development issues were resolved as well. On August 4, 2000, in response to SWFWMD's request that the County provide documentation of drainage easements and/or OFP's acceptance of the increased lake stages on OFP property, the County submitted a proposed and un-executed Perpetual Flowage and Inundation Easement and an Acknowledgment to be signed by OFP accepting the increased lake stages. On August 7, 2000, the OFP property was annexed by the City of Bartow (the City). On October 16, 2000, the City enacted Ordinance No. 1933-A approving OFP's DRI application. The City's DO contained essentially the same provision on Off- Site Flow contained in the County's DO. See Finding 18, supra. However, the City's DO specified that the historical flow study was required to be reviewed and approved by OFP (as well as by the County and by SWFWMD). OFP has not given formal approval to historical flow studies done to date. On October 6, 2000, SWFWMD issued a Notice of Final Agency Action approving Polk County ERP No. 4419803.000. Permit Specific Condition No. 7 provides that "all construction is prohibited within the permitted project area until the Permittee acquires legal ownership or legal control of the project area as delineated in the permitted construction drawings." As a result of this permit condition, the County cannot undertake construction as authorized under the Permit until any needed easement or legal control is obtained. Precise Easement Route Approximately two months before final hearing, a dispute arose as to the precise cross-flow easement route proposed by the County. OFP had understood that the County's proposed route was based on a detailed survey. But closer scrutiny of the County's proposed route indicated that it cut corners of existing lakes on OFP's property, crossed residential lots proposed by OFP, and veered north into uplands (also proposed for residential use) in the western portion of the route before looping south and then north again to the outfall at Lake Hancock. Information subsequently revealed in the course of discovery suggested that the County's proposed route may have been based on pre-reclamation topography of OFP's property. After OFP recognized the implications of the cross- flow easement route being proposed by the County, OFP provided the County with several different alternative easement routes through the OFP property. While agreement as to the precise route has not yet been reached, the precise route of the easement is not significant to the County, as long as water can flow across OFP property to Lake Hancock and so long as the County does not have to re-locate existing ditches. Such adjustments in the location of the proposed flowage easement would not affect SWFWMD staff's recommendation for permit issuance, as long as it covered the defined project areas. In addition, OFP's current site plan is a preliminary, conceptual plan subject to change before it is finalized. Regardless what cross-flow easement route is chosen, it will be temporary and subject to modification when OFP's development plan is finalized. If the County is unable to not negotiate a flowage easement across OFP property, it could obtain whatever easement is required through use of the County's eminent domain powers. The County's acquisition of an easement to accommodate a flowage route and anticipated increased stage on OFP property gives reasonable assurance that any stage increases will not cause adverse impacts to OFP property and gives reasonable assurance that the County will have sufficient legal control to construct and maintain the improvements. Project Area The County applied for a Standard General Permit and specified a total project area of 0.95 acre. This acreage reflects the area required for actual construction and alteration of control structures and drainage ditches in the preexisting Eagle-Millsite-Hancock system. It does not reflect the entire acreage drained by that system (approximately 1,800 to 2,000 acres). It also does not reflect the area of the cross-flow easement, which the County has yet to obtain. When determining project size for purposes of determining the type of permit applicable to a project, SWFWMD staff considers maximum project area to be limited to the acreage owned or controlled by the applicant. In addition, since this is a retrofit project for improvement of an existing drainage system not now owned or controlled by the County, SWFWMD staff only measured the area required for actual construction and alteration of control structures and drainage ditches. Future easements necessary for future maintenance of the system were not included. When OFP applied for its conceptual ERP for its proposed DRI, the project area was considered to be the acreage owned by OFP. The rest of the basin draining through OFP's property to Lake Hancock (again, approximately 1,800 to 2,000 acres) was not considered to be part of the project area. Water Quantity Impacts The County's project will retrofit certain components of the same drainage system which OFP will utilize for surface water management and treatment pursuant to its conceptual ERP. Modeling presented in the County's application demonstrates that there will be some rises and some lowering of some of the lake levels on OFP's property during certain rain events. Anticipated rises are lower than the top of banks authorized in OFP's conceptual permit; hence the system will continue to function properly. While there are some differences in the County's permit application and OFP's conceptual permit application concerning modeling estimates of flow rates through OFP property, the differences are minor and are attributed to differences in modeling inputs. The County used more detailed modeling information. Any such differences are not significant. Differences in flow rates provided in the County's proposed permit and in OFP's conceptual permit do not render the permits as incompatible. If the County's permit were issued, any modeling undertaken in connection with a subsequent application by OFP for a construction permit would have to be updated to include the County's improvements to the system. This outcome is not a basis for denial of the County's permit. While the rate at which water will flow through the system will increase, no change in volume of water ultimately flowing through the drainage system is anticipated as a result of the County's proposed improvements. The increased lake stages which are anticipated to occur on OFP property as a result of the County's project will not cause adverse water quantity impacts to the receiving waters of Lake Hancock or adjacent lands. The project will not cause adverse flooding to on-site or off-site property. The project will not cause adverse impacts to existing surface water storage and conveyance capabilities. The project will not adversely impact the maintenance of surface or ground water levels or surface water flows established pursuant to Chapter 373.042, Florida Statutes. Water Quality Impacts No adverse impacts to water quality on OFP property are anticipated from the County's proposed drainage improvements. The project will not add any pollutant loading source to the drainage system and is not expected to cause any algae blooms or fish kills in OFP waters or cause any additional nutrient loading into OFP's surface water management systems. As reclaimed phosphate mine pits, the lakes on OFP's property are high in phosphates. Meanwhile, water quality in upstream in Millsite Lake and Eagle Lake is very good. Off-site flow of higher quality water flushing the OFP lakes will improve the water quality on the OFP site. The County's project will have no adverse impact on the quality of water in the downstream receiving of Lake Hancock (which currently has poor water quality due in large part to past phosphate mining). Upstream of OFP, the project will not cause any adverse water quality impacts and is anticipated to result in positive impacts by lessening the duration of any flooding event and thereby lessening septic tank inundation from flooding. This will have a beneficial impact on public health, safety, and welfare. Thus, there is a public benefit to be gained in having the County undertake the proposed drainage and flood control improvements now, rather than waiting for OFP to finalize its plat and construct its development project. The County's proposed improvements do not require any formal water quality treatment system. The improvements are to a conveyance system and no impervious surfaces or other facilities generating pollutant loading will be added. Upstream of OFP, the Eagle-Millsite-Hancock drainage system flows through natural lakes and wetlands systems that provide natural water quality treatment of the existing drainage basin. OFP expressed concern that the County's improvements to drainage through these areas (including the ditch maintenance already performed in 1998) will increase flow and reduce residence time, thereby reducing natural water quality treatment. But ditch maintenance does not require an ERP, and the County gave reasonable assurances that reduction in natural water quality treatment will not be significant, especially in view of the good quality of the water flowing through the system out of Eagle Lake and Millsite Lake. As a result, it is found that the County's proposed project will not adversely affect the quality of receiving waters such that any applicable quality standards will be violated. Indeed, OFP's expert consultant conceded in testimony at final hearing that OFP has no reason to be concerned about the quality of water at present. Rather, OFP's real concern is about water quality in the future. Essentially, OFP is asking SWFWMD to require the County to guarantee OFP that future development in the area will not lead to any water quality problems. Requiring such a guarantee as a condition to issuance of an ERP would go far beyond SWFWMD requirements and is never required of any applicant. Besides being speculative on the evidence in this case, future development in the area will be required to meet applicable SWFWMD water quality requirements. SWFWMD permitting required for such future development would be the proper forum for OFP to protect itself against possible future reduction in water quality (as well as possible future increase in water quantity). Environmental Impacts The drainage ditches to be improved by the County's project were originally constructed before 1984. These upland cut ditches were not constructed for the purpose of diverting natural stream flow, and are not known to provide significant habitat for any threatened or endangered species. The County provided reasonable assurance that the proposed project will not change the hydroperiod of a wetland or other surface water, so as to adversely affect wetland functions or other surface water functions. The functions of the wetlands and surface waters to be affected by the proposed project include conveyance, some water quality treatment, and possibly some wildlife movement or migration functions between the wetlands served by the ditches. Wetland impacts from the project consists of .63 acre of permanent impacts and .21 acre of temporary impacts, for a total of .84 acre of impact. The permanent impacts consist of the replacement of pipes with new structures in the ditches and the addition of rip rap in areas to prevent sedimentation and erosion. The proposed project's anticipated increase in the rate of flow is expected to lessen the duration of any flooding event at the upper end of the drainage system, and at the downstream end is expected to create a subsequent rise in some of the lakes and storage areas on the OFP property during certain rain events. The anticipated rise in some of the reclaimed lakes on OFP property is not anticipated to have any adverse impact on the functions that those surface waters provide to fish, wildlife or any threatened or endangered species. The reclaimed lakes subject to rise in water levels for certain rain events are steep-sided and do not have much littoral zone, and little, if any, loss of habitat will result. The County's application provides reasonable assurance that the anticipated stage increase in affected wetlands or surface waters will not adversely affect the functions provided by those wetlands or surface waters. The County provided reasonable assurance that the proposed project will not violate water quality standards in areas where water quality standards apply, in either the short- term or the long-term. Long-term effects were addressed in Finding 43-51, supra. Short-term water quality impacts anticipated during the construction of the proposed improvements will be addressed through the use of erosion and sediment controls. The proposed project also will not create any adverse secondary impacts to water resources. The project will not cause any adverse impacts to the bird rookery located to the north on OFP property. The project will not cause any adverse impacts to the bass in OFP's lakes, a concern expressed by OFP relatively recently. To the contrary, since the project will improve water quality in OFP's lakes, the impact on OFP's bass is expected to be positive. OFP raised the issue of a bald eagle nesting site located on its property. The evidence was that a pair of bald eagles has built a nest atop a Tampa Electric Company (TECO) power pole on the property in October of each year since 1996. Each year the pair (which is thought to be the same pair) has used a different TECO power pole. Most of the nests, including the one built in October 2000, have been on poles well south of any construction proposed under the County's ERP and clearly outside of the primary and secondary eagle management zones designated by the U.S. Fish and Wildlife Service. But one year, a nest was built on a pole farther north and possibly within the secondary eagle management zone. OFP presented testimony that U.S. Fish and Wildlife would require OFP to apply for an "incidental take" in order to build homes within the primary eagle protection zones around any of the four poles on which eagles have built nests since 1996; timing of construction of homes within the secondary protection zones may be affected. Even accepting OFP's testimony, there was no evidence as to how U.S. Fish and Wildlife would view construction of the County's proposed drainage improvements on OFP property within those zones. In addition, the evidence was that, in order to accomplish its DRI plans to build homes in the vicinity of the TECO power poles that have served as eagle nests in recent years, without having to apply for an "incidental take," OFP plans to place eagle poles (more suitable for eagle nests than power poles, which actually endanger the eagles) in another part of its property which is much more suitable habitat in order to encourage the eagles to build their nest there. The new location would put the County's proposed construction activity far outside the primary and secondary eagle management zones. Other Permitting Requirements The County's proposed project is capable, based on generally accepted scientific engineering and scientific principles, of being effectively performed and of functioning as proposed. The County has the financial, legal, and administrative capability of ensuring that the activity proposed to be undertaken can be done in accordance with the terms and conditions of the permit. No evidence was presented by Petitioner that the Project will cause adverse impacts to any work of the District established under Section 373.086, Florida Statutes. No evidence was presented by Petitioner that the project will not comply with any applicable special basin or geographic area criteria established under Chapter 40D-3, Florida Administrative Code.
