Findings Of Fact Petitioner, the Association, represents 1,053 condominium homeowners located in the Old Port Cove Community, a residential development in Palm Beach County, Florida. Old Port Cove Community consists of seven separate condominium buildings and associations. Many of the individual condominium homes/apartments within the complex border on arid overlook the Old Port Cove area of north Lake Worth which is the location of the two existing marinas operated by the Respondent Applicant and the site of the proposed marina expansion. The water in question is an essential part of the residential community and was, in many cases, a major factor considered by the homeowners purchasing in this community. At the time of development, going back a minimum of seven years, property owners were advised by the developer/Applicant (or its predecessor) that the marinas constructed or to be constructed would be for the exclusive use of the residents of the condominium apartment houses within the complex. On or about March 12, 1986, Respondent DER, received an application from the Applicant for a dredge and fill permit for the construction of a commercial addition to the northernmost marina currently existing at Old Port Cove Complex. The new construction was to consist of 1 pier of a total length of 911 feet with 50 boat slips and 26 finger piers. The new slips will be 45 feet in length of which 15 feet will consist of pier and the remaining 30 feet of open water terminated by a piling. The main pier would extend in a northeast direction from the easternmost point of the existing north pier for a total of 171 feet, then turn northwest for a total of 490 feet, and then turn southwest for an additional 250 feet to enclose an area of water leaving a 90 foot wide space for entry of boats into the enclosed area. The application for the permit contains as an attachment thereto an engineering drawing depicting the proposed marina expansion and its relationship to the existing marina. This expansion was proposed because of the growing need for boat slips in the area. The operator, currently providing a total of 289 slips in both marinas, (197 in the south and 92 in the north) proposes to construct 50 new slips for pleasure boats from 25 to 120 feet in length. Applicant proposes and commits itself to utilize the new slips for sailboats only. Notwithstanding the fact that there are approximately 1,261 additional slips available within a one mile area of the proposed site, the applicant contends it has been continuously turning away applicants for slip rentals in its facilities. If approved, the proposed new facility will constitute an approximate 4 percent increase in the total number of boat slips in the area, not counting the free moorings offshore in the Federal mooring in the center of the cove. Applicant presently operates one diesel fuel pump at the South Marina. No other fueling facilities exist at either marina operated by Applicant nor are any additional fueling facilities intended. Applicant has also entered into a contract with a local fuel spill control company to provide spill cleanup if necessary. At the present time, there are no pump-out stations for sewage at either the North or South Marina. Applicant proposes to install sewage facilities as a part of the approval package. Leasing agreements currently in effect require all boats using the marinas to certify they have U.S. Coast Guard approved heads on board before being allowed to dock at the marina. This requirement is not actively enforced, however. Most boats utilizing the facility are pleasure/non-commercial fishing boats. Individuals, mainly residents of the apartment complex, use the docks for fishing but there is some question as to the nature and availability of the fish population in the area. Manatees do frequent the area, however, not necessarily as far north as the marina in any great numbers, but several hundred yards to the south, congregating at times around the entrance to the intracoastal waterway which forks off to the northwest somewhat south of the south marina. Subsequent to the receipt of the Association's Petition herein, DER had numerous water quality tests performed and requested certain assurances from the Applicant designed to remedy or rectify numerous objections made by the Association in its Petition. Thereafter, on February 16, 1987, DER issued a Revised Intent to Issue in this case in which it addressed the Association's concerns and specified certain conditions to be included in the permit to protect the water quality and biological resources in the project area. These conditions included: A prohibition against commencement of any excavation or other construction activity prior to receipt of evidence of permission from the Trustees of the Internal Improvement Trust Fund or DNR; A requirement for notification of the Division of Archives in the event any historical or archaeological artifacts are discovered within the project site; Provision for permanent sewage pump-out facilities to be provided at the south marina to replace portable facilities currently available, within 90 days of permit issuance, and the provision of temporary sewage pump-out facilities at the north marina which shall be in place and functioning prior to any work being commenced under the permit; The requirement for use of turbidity screens around the project site during construction to remain in place until turbidity behind. The screens falls to an acceptable level; The placing of educational signs, the content of which shall be coordinated with DNR, at both the north and south marinas, informing boaters that manatee may be in the area and requesting that care be taken; The posting of manatee warning signs in both marinas; The establishment of idle speed and no wake zones in both marinas and the access channels; A provision that permanent liveaboards connect their vessels with permanent sewage hook-ups at all times when the vessel is docked; and A provision against refueling facilities at the expanded north marina. Applicant and DER are satisfied that the conditions imposed by the terms of the Revised Intent to Issue satisfy all the current requirements of the statute and rules relevant to dredge and fill permits for projects of this nature. Many of the apartment owners, banding together as the Petitioner Association herein, strongly resist approval of the permit to construct the new marina for numerous reasons. They contend, first, that the construction of the new marina and the greater number of boats resulting therefrom, constitute a threat to the manatee population in the area. The Association is also concerned with water quality in the area, fire safety, wake damage, and noise pollution as a result of the proposal. Other considerations of the residents include parking and a diminishment in the resale value of their property. Several of the residents have seen manatee in the area swimming in the waters adjacent to the marina and in the "key" area on the other side of the peninsula. Many have scars on them and appear to have been injured by collisions with boats. Several residents have seen trash and debris in the water and have observed boats traveling at a high rate of speed just outside the existing marinas. In addition to debris, residents have seen oil and grease floating on the water and contend that the proposed wave baffles hanging down into the water from the extended pier will interfere with the natural flushing action of the winds and tides. Many of these same individuals complain of an extremely bad odor coming from the marina and they have observed boat owners either pumping their bilges directly into the marina water or washing their boats with detergents which are allowed to run overboard into the water. At least one resident, speaking for others as well, referred to a green space, an area of grass outside and between the buildings and the water. Originally, this area was supposed to be gardens and a recreational area for the residential complex, and the yacht club was to be a secondary appurtenance for the property owners. Now, with apartment owners making up no more than 10 percent of the occupants of the marina slips, for it seems as though the apartment residence owners are being shunted to the background and commercial activities, including the marina, are becoming paramount in the eyes of the applicant which still operates it. This green space is now proposed to be converted by the applicant to parking for the use of the marina patrons; all to the detriment of the apartment owners. There is some evidence that boat owners utilize the grounds of the apartment complex as a place to walk their dogs for canine toilet purposes and there is some evidence that numerous liveaboard boat owners, who do not have adequate toilet and bathing facilities on board their boats, utilize the pool, showers, and toilets ordinarily reserved for residents of the apartment complex. Noise from parties on the boats is often both excessive and disturbing and to the knowledge of at least some of those testifying on behalf of the Association, efforts by security personnel employed by the condominium associations to get the boat owners to curb the noise and disruption have been totally unsuccessful. One resident summed up the feelings of his co-owners when he indicated that these various factors translate to property value and because of the current situation with pollution, noise, lack of security, and the increasing commercialism, the result has been a substantial drop in property value. This witness feels that the more slips that are made available, along with their related annoyances, the less the value of the individual apartments will be. All feel that the addition of 50 more slips will increase the existing problems and none of the residents who testified for the association were of the opinion that the developer's controls will be adequate to alleviate or minimize the untenable situation which they now face. However, there was no evidence presented to substantiate the layman opinion of reduction in property value and it cannot be said, therefore, that this has or will really happen, and the amount of loss. Turning to the issue of water quality as effected by refueling operations and sewage disposal at the marina, the question of fueling facilities was not raised by the Association other than to object basically because of the potential for fuel spills. Applicant and DER contend that this problem should be taken care of through the contracting for the services of Glasgow Equipment Service, providing for 24 hour emergency response for fuel spills of any type. It is unreasonable to expect that a marina providing dockage for potentially as many as 289 motor vessels can be expected to be totally spill free. If proper refueling procedures are followed, and there is no evidence to indicate that they would not be, the incidence of fuel spills should be minimal and the contract with the clean-up service providing for around the clock response in case of a spill, appears to be adequate action to remedy the effects of any spill. There have been very few fuel spills in the history of the marina operation. The most recent resulted in a spill of no more than 3 to 5 gallons and clean-up was successfully accomplished with little damage. The Association made much of the fact that no disciplinary action was taken against the offender and that the boat in question is still an occupant of the marina. This incident is still under investigation, however, and final action has not yet been taken. At the current time, there are no pump-out stations for sewage at either the north or south marina. The applicants propose to install a pump-out sewage facility tied to each vessel berth in the south marina and to provide a portable pumpout facility which can be rolled to a particular spot to meet the needs of any vessel at the north marina. The Applicant has agreed to fund the project completely and has agreed to the special conditions contained in the Revised Intent to Issue regarding the pumping stations. Applicant and DER both arranged for testing of the water quality at the north marina to determine the current condition of the water. Dr. John D. Wang, an expert in coastal hydrodynamics on the faculty at the University of Miami, is familiar with the site of the proposed expansion and visited it last in November, 1986. At that time, he did a study on the flow exchange caused by tides and wind over a two day period. As a part of his test, he placed instruments in the water to take measurements of water motion, temperature, and salinity on the outer side of the current pier at the north marina and inside that marina at different depths. On the first day of the test, the tide was an ebb tide (receding) pulling water out of the marina area. However, at the same time, the wind was from the southeast which directly opposed the tide action. At the surface, the drogues (instruments) followed the wind. Those deeper in the water went with the tide. When the tide came in the next day, the drogues went to the north under the power of both wind and tide. Dr. Wang's experiment confirmed not only that the water moved in and out of the marina area, but also that the water circulated clockwise north along the west side of Lake Worth and south on eastern side. Dr. Wang thought this might be due to wind force, but regardless of the cause, it was a good indication that water was exchanged in the area. Dr. Wang concluded that the water in the marina was completely taken out within one hour and joined the circulatory pattern, being replaced by other water. The baffles placed on the piers to reduce wave motion will have some effect on the water circulation tending to reduce surface flow, but these baffles will not prevent the exchange of water due to circulation because they are limited to the top three feet of the water. In Dr. Wang's opinion, they may have some positive effect on circulation by preventing wave water from flowing back out. By the same token, the presence of boats in the marina will have but a marginal effect on water exchange. The draft of the boats utilizing this area is not much more than the wave baffles and there will still be ample water underneath to permit flow and exchange. In fact, in Dr. Wang's opinion, the location of this marina is almost optimal. By virtue of the fact that it is out in the open, water can flow freely through the area and no dredging is required. The flat, sloping bottom promotes water exchange. No evidence was presented to contradict this opinion and it is hereby accepted. Additional tests on water quality were run by Dr. Paul R. McGinnes, head of an independent consultant laboratory specializing in water quality and motion who visited the site several times doing three separate studies of dissolved oxygen, salinity, and water temperature at various depths and at different hours. As a part of his examinations, he also looked for oil (pollutants), and bacterial components. The water subject to tests for bacterial components was taken from the top foot at several locations in each of the three studies. In the 1983 study, tests showed fecal and coliform bacteria were present in sufficient quantities to constitute a few violations. In 1986, when he sampled for fecal bacteria only, the count was very low. In the 1987 test of samples taken twenty times over 24 hours, the fecal bacteria count was, in each case, within state limits. As to heavy metals, in 1983, levels of lead, cadmium, mercury, and zinc were not present. There was no evidence as to current levels. As to oils and greases, all studies showed very little present (below 5mg per litre) and what grease was there could consist of animal or vegetable fats. This is considered unlikely and it is found there is petroleum product in the water, though in insignificant quantities. Regarding dissolved oxygen, all tests showed compliance with state standards. Levels were comparable to other areas of Lake Worth. Dr. McGinnes is generally familiar with the state standards for Class III waters and believes the construction and operation of the new 50 slips at the north marina will in no way result in violation of state water quality standards. His opinion as to this construction is based on his tests, his conversations with applicant's personnel, and his experience with other similar projects. Granted, boats do tend to leak oil and that situation will raise the oil level in the immediate area of the leak. However, not all boats leak in all marinas and what leaks there are will tend to dissipate to a safe level within a very short period of time. In February, 1983, the coliform bacteria in the south marina were higher than in the north marina or in Lake forth in general. However, coliform bacteria does not appear to be a major problem in this case. In response to cross examination, Dr. McGinnes concluded that even if five boats dumped raw sewage in the north marina, it would not have any major negative impact on the overall water quality there. It would, of course, affect the sample taken in the area immediately after dumping, but not the overall quality over the long run. Dr. McGinnes' last sample was taken in February, 1987, which is a time of highest use. The water quality in and around the marina is generally as good as in the northern end of Lake Worth which is better than in the southern end of the lake. His examination of the water quality indicated no recognized violations of Florida water quality standards in the last two reports. The association's expert, Mr. Timmer, went to Old Port Cove in January, 1987 and saw numerous boats in the slips. He looked for inlets opening into the marine and for a bird population, either one of which could cause an increase in undesirable bacteria in the area. He found none. He took water samples for testing to see if the fecal coliform bacteria level in the marina was higher than outside it. During his tests, he took samples from 14 sites at three separate depths at each. His samples were duplicated for safety in case any one sample was compromised. Six of his samples were taken inside the dock area of the north marina; one was taken to the north several thousand yards; and four more were taken outside the area of the proposed marina. One was taken in the federal anchorage; several across the cove on the east side of the lake and one outside the cove, south of the Intracoastal Waterway inlet and west of the channel. The furthest test site was approximately one mile from the marina. When Mr. Timmer got his samples, he isolated the sets from each other; "refrigerated" them (placing them in a cooler without any ice), and upon completion of his sampling, took them to the McGinnes lab where analyses were done for fecal coliform bacteria. As a result of his tests, and relying on the report received from McGinnes Laboratories, Mr. Timmer concluded that the fecal coliform level within the marina was higher than outside the marina by 5 to 10 times. Surface samples, he felt, averaged out in excess of what he considered to be the state standard. Some of the lower level samples were high also. In no case, however, did any sample exceed a count of 15 outside the marina. Coliform standards, according to state rules, are to be averaged over a month's period of taking. In fact, the report received from the McGinnes lab concluded that because testing was not done over a month's period, the standard was not exceeded. These samples, even that one reflecting a reading of 560 bacteria per 100 ml at site 3a, did not come anywhere near the upper limits of the state standard and in fact was well within it. Mr. Churchill, a zoologist and ecologist and expert in marine biology made various studies of the benthic communities and fish population in the area of the proposed construction. He studied the soft bottom communities and took samples of the bottom in different areas both inside and outside the current marina and in the area where the extension is proposed. He found that the outside and the outer inside communities were much the same and had a low number of species. The inner inside was considerably different. It had a higher number of both species and individuals. A larger number is a better system and DER rules provide that one cannot build a project which would tend to reduce the number. Here, since the area where the construction is planned is outside the area of high species count and similar to the rest of the cove area, the construction would most likely not violate the state's rule. In fact, in Mr. Churchill's opinion, concurred in by other experts, the proposed project will, rather than negatively impact the environment for wildlife, enhance it by providing additional habitat. The pilings, forming supports for the piers and ties for the boats will provided habitat for small marine life which in turn provide food for larger life which is attracted. This testimony would tend to contradict the testimony of at least one of the residents who indicated that in his experience, the fish population in the area had declined radically over the years since he moved in and that about all one can catch in the immediate area now are some small sheepshead. This is in comparison to the larger variety and size of fish available to the angler several years in the past. No doubt, the fish selection and availability has diminished since the area was developed, but the question is whether the new construction will aggravate that situation and the answer appears to be that it will not. An additional water quality study was conducted by Dr. Martin Roessler, a marine scientist who did a water quality study in the area consistent with that done by Dr. McGinnes. He also did several of his own on- site inspections as to water clarity and marine plant and other life including reptiles and birds in the area. On his third visit to the site, he took water quality samples for testing for bacteria and other marine life. As a result of his tests, he concluded that water quality in the area should not be diminished by construction of the marina. During construction, the use of turbidity curtains and booms will tend to keep any temporary disruption to a minimum. He agrees with Dr. McGinnes and Mr. Churchill that the nature of marine life within the area should not be disturbed by the construction. He was unable to observe any sea grasses in the area (they are on the other side of the cove and not where he observed) and dredging would not be involved; only the driving of pilings which will disrupt the bottom only in the immediate area of the piling. Dr. Roessler's credibility was not damaged by the Association's evidence that a previous study done for another agency was rejected and he was not paid for the work done. There was insufficient evidence of detail and a broad-brush smear can not be held effective here. When Old Port Cove submitted it's application for its permit, it included the original draft and all requested information in a final product. This project documentation was evaluated by Ms. Janet Llewellyn, a supervisor with DER, who is an individual fully conversant and familiar with the dredge and fill rules and standards set forth in the statutes and the F.A.C. As to water quality, Ms. Llewellyn analyzed the information submitted by the applicant in response to her request for water samples at certain locations she had identified. These samples showed no current violation of the rules governing dissolved oxygen and fecal or coliform bacteria even with the boats that are currently in the marina. DER also requested "hydrographic information as a part of the reasonable assurance" test and this information was to deal with existing water quality and the flushing action of the tides and winds. Ms. Llewellyn has visited the site, albeit only shortly before the hearing, and as a result believes that the drawings submitted with the permit application are correct and represent the work to be done accurately. Recognizing that the field inspection report submitted by on-scene local DER personnel is somewhat negative in its evaluation of the project, she nonetheless disagrees with certain portions of this report which say that boats and piers will interfere with the flushing action of the wind and tide. She also disagrees with the statement that oil and grease will continue to degrade water quality. She feels that the inspector who did the report did not have available to him the hydrographic and water quality tests that she had. This information, submitted somewhat earlier, was sent to Tallahassee by the experts and was not forwarded to the field representative when the request for the survey was laid on. The Revised Intent to Issue, including as it does, the additional requirements laid on the applicant in such areas as sewage pump-out, liveaboards, fueling facility prohibitions, and the like came about as a result of misunderstandings between DER and the applicant and culminated in the applicant agreeing to try to ameliorate the situation and the issuance of the permit by compromise as suggested. DER is satisfied with the proposals contained in the Revised Intent to Issue and feels that approval of this permit will upgrade the facilities at the south marina as well as insure compliance with state water quality standards at the north marina. Together it will result in an upgrade in the water quality in the area. Ms. Llewellyn is convinced that there will be no negative effects on the water quality by the construction at the north marina and that the criteria contained in both the statutes and the rules, from an environmental standpoint, will not be violated. DER has no authority to consider other factors which appear to be among the most substantial complaints of the association members. She did not consider the possibility of damage to the scenic view by the addition because she did not consider it to be an issue. In her opinion, the question of damage to the property of others relates to damage to structure, property, wildlife, etc., and the impacts to these would be negligible. What she considers important is that the permit involved here is for construction, not operation of the marina and enforcement of continuing operational rules is another consideration entirely. When using the term "assurance" as a requirement for an applicant, the assurance required is not that the new slips will have no adverse impact, but that any adverse impact will not reduce the water quality below standards set out in the statutes and rules. Though not envisioned, water quality can be reduced from very high quality to high quality (a reduction in quality) and still be within standards. Additional scientific examination of the water and the immediate site was conducted by Dr. Kenneth L. Echternacht, a hydrographic engineer, physicist, and physical water quality expert with DER who reviewed the hydrographic study submitted with the application. He found that the drogue study showed water speeds of between .05 to .1 feet per second which was typical of the area. The placing of drogues and the resultant study and conclusions was not flawed by the lack of education of the individual who did the placing at the direction of the scientist. What is important is the education and knowledge of the supervising scientist who will take the information gathered and examine it. Considering that prevailing winds in this area during daylight hours are from the sea to the land, (SE to M), and at night the reverse occurs, any study made only during daylight or during nighttime would be flawed to the extent that it would examine only one part of the equation. Given the baseline information available to him, Dr. Echternacht concluded the project as described would not adversely effect water quality from a hydrographic standpoint. Flushing and circulation are important to water quality. If the water does not move, the pollutants added by outside factors, (here boats), accumulate and build up. On the other hand, the faster the water moves, mixed with turbulence, the faster the pollutant is disbursed and prevented from accumulating. At .05 f/sec, a particle of water would move 180 feet per hour. As a result, water will move the length of the marina, (450') in 2 1/2 hours. Therefore, if a spill occurred at the south boundary during an incoming tide, it would move to the north boundary of the marina within 2 1/2 hours and given a tide cycle of 6 1/2 hours, would still have 3 1/2 to 4 hours to move even further away, mix with other water, and be disbursed before being brought back to the marina by the outgoing tide. (However, there is evidence that the water moves in a clockwise direction and the likelihood is great that the contaminated water would not even come back to the marina but would head out down the eastern side of the cove.) This is a worst case situation because of the slow water movement rate utilized and it is, itself, a relatively fast movement. Admittedly, this water movement will be affected by obstacles in the water such as boat hulls, posts, pilings, and baffles. However, while these factors would slow up the water, they would also create turbulence and vortices in the water which, themselves, help mixing. From a practical standpoint, other factors are involved such as the size of the obstacle, etc. Here we are faced with a situation where the marina is not enclosed and the water flows freely. The water quality can be expected to be better than in an enclosed marina and even better in the new area than in the existing areas because it will be further away from the seawall. Taken together, in light of the evidence presented by both sides, it is found that a diminishment in water quality as a result of the construction of the proposed facility here would be minimal and would in no case, likely result in a reduction of the water quality to a level below that considered acceptable in the state statutes and rules. In addition to water quality, the residents were concerned about the threat of injury to the manatee population which, while not appearing in the immediate area of the proposed construction on a regular basis, does visit the area periodically. In addition, there is substantial evidence to establish that boats coming into and out of the marina, going down through the channel into the main part of Lake Worth and out through the cut, would pass through areas actively populated and visited by manatees and therefore, the opening of 50 additional slips for new boats, even in this less populated area, could have a substantial impact on the manatee population. There is no doubt that manatees do visit the area. There are sea grasses, if not in the immediate area of the proposed marina, certainly on the opposite shore of the north part of Lake Worth. It is uncontroverted as well that manatees have been seen near the marina and in the key area on the other side of the peninsula. However, the evidence introduced by the association's own witnesses, Mr. Rose and Dr. Odell, indicates that the manatee population tends to congregate in areas south of the entrance to the Intracoastal Waterway which, itself, is south of the Old Port Cove area. Many manatee congregate in the warm waters produced by the Riviera Beach power plant in the southern part of Lake Worth and go from there to other areas within the Lake Worth area to feed, even as far north as Hobe Sound and Loxahatchee. Generally, there are not enough sea grasses in the local area to keep them there. Manatees can range up to 12 feet in length and up to 3500 pounds in weight. Manatee deaths in Palm Beach County, of which boat deaths account for approximately 50 percent, are a serious danger to the survival of the manatee population. The greatest danger to manatees comes from power boats. While there is no evidence that sailboats are dangerous since they move slowly enough for the manatee normally to evade then, there nonetheless may be some danger as a result of their presence. Some manatees are crushed by barges and larger power boats. Some are killed by impact with medium and larger boats. In approximately 40 percent of the cases, impact kills without propeller injuries and it is hard to tell the size of the boat which did the damage. As to propeller deaths, boats from 24 feet up can kill by this method. The number of manatee deaths has increased lately as a result of boat and other man related causes and if this trend continues, the manatee population will decline and, possibly, become extinct. Mr. Rose, who is quite familiar with the habits of the manatee in this area, states that it is most likely that in traveling north to Hobe Sound and environs, the manatee would travel up the Intracoastal Waterway (the entrance to which is south of the proposed construction) and not go into the Old Port Cove area. Even if they were following the grass which runs along the east and north shores of Old Port Cove, the grass does not grow on the marina side and it is unlikely the manatees would come to the marina in the west to feed though they might come for other reasons and in fact have been seen in the "key" area. Dr. Odell, perhaps the foremost authority on manatees in the United States, has visited the area and, at this hearing, heard the testimony of the other witnesses. He contends that because of the food available in the form of sea grasses and mangrove seeds, primarily on the eastern side of the cove, the likelihood is that manatees would be found in that area. This is consistent with the testimony of Mr. Rose. Consequently, it is found that while manatees come to the area of the proposed marina from time to time, it is more the stray manatee than evidence of continued habitat. Dr. Odell's studies indicate that between 1974 and 1985, there were no manatee deaths recorded in north Lake Worth. However, it is possible that the dead manatee found elsewhere may have been injured or even died elsewhere, (possibly near Old Port Cove) and there well may have been others who were injured in the area who went elsewhere to die. There is, however, no evidence that this is the case. Dr. Odell considers that boats with a draft of between 5 and 7 feet would leave little clearance from the bottom in the bottleneck area south of the marina where the water depth is no more than 9 or 10 feet, to allow room for the manatee to avoid them. In fact, he feels that large, inboard powered boats pose the greatest threat to the manatee. While sailboats generally do not create a risk to the mammal, if the new 50 slips were to be limited to sailboats but all existing slips were to be converted to power boats, this would constitute a severe threat to the manatee population. Further, a change in use patterns, creating more traffic, would increase the risk to the manatee. The real issue is, however, how much time boats spend in manatee habitats. The more boats there are, the less desirable the situation. (Both experts agree, however that if the 50 new slips are limited to sailboats and the ratio of power boats to sailboats in the existing slips is not increased, there is really no legitimate reason, based on a threat to the manatee population, to deny this construction permit.) It would appear, then, that the risk to the manatee population is acceptable. Signs advising boaters to slow down and beware of manatee are good only so long as they promote awareness. There is, according to Dr. Odell, no evidence that they have reduced manatee mortality and given present trends of more power boats and the destruction of the manatee's habitat, one can expect the manatee population to decrease even further.

Routa, Esquire Post Office Box 1386 213 South Adams Street Tallahassee, Florida 32302 =================================================================
The Issue The issue for determination in this proceeding is whether Respondent, E. Speer and Associates, Inc. (the "Applicant"), should be granted a permit for the construction of a permanent docking facility pursuant to Sections 403.91-403.929, Florida Statutes, and Florida Administrative Code Chapter 17.
Findings Of Fact Whether Quantified Hydrographic Studies Are Necessary For All Marina Applications To Provide Reasonable Assurance That Flushing Is Adequate To Prevent Violations of Water Quality Standards Speer's Exceptions Nos. 1, 4, 5, 6, 7 and 8 in whole or in part take exception to the Hearing Officer's conclusion (stated as a finding of fact) that it is not possible to demonstrate adequate flushing without "quantifying flushing rates and pollutant dispersal rates using objective methods and appropriate hydrodynamic data." (R.O. at 20, 22-24, 47, 49-50, 54, 57-58; F.O.F. Nos. 33, 35, 38-39, 40, 43-45, 64, 66, and 69) It is clear from the tenor of the entire recommended order that the Hearing Officer believes that as a matter of law an expert's opinion is not sufficient to provide reasonable assurances that flushing will be adequate to prevent violations of water quality standards unless that opinion is based on quantified conclusions generated by objective methods and appropriate hydrodynamic data. (R.O. at 47, 49-50, 57-58) Thus, for example, the Hearing Officer opines that quantification of flushing rates and pollutant dispersal rates using objective measurements of appropriate hydrodynamic data is an essential element of the prima facie showing required to be made by the applicant. (R.O. at 47; C.O.L. No. 11) The Hearing Officer places great significance an the following excerpt from the opinion in 1800 Atlantic Developers v. Department of Environmental Reculation, 552 So.2d 946 (Fla. 1st DCA 1989), rev. den., 562 So.2d 345 (Fla. 1990): 1800 Atlantic filed 34 exceptions to the recommended order, most of which were denied in the Department's final order . . . . The final order approved and adopted most of the findings of fact and conclusions of law in the recommended order and denied the permit. The following stated rulings and reasons there for are significant to the issues on this appeal. (emphasis added) We must note at this point that there is no finding of fact in the hearing officer's recommended order that quantifies how productive the marine habitat may be in this case, and no record support for the suggestion that there would be some quantifiable diminution in the quality of the marine habitat attributable to this project [footnote omitted]. (emphasis added) Exception 23 filed by 1800 Atlantic challenged the hearing officer's finding that the project will adversely affect the conservation of fish and wildlife, fishing or recreational values, and marine productivity in the vicinity . . . The Department rejected this exception based upon the hearing officer's general statements, without any quantification whatsoever, of adverse effects upon these matters . . . (emphasis added) 1800 Atlantic, 552 So.2d at 951-952. I do not concur that 1800 Atlantic stands for the proposition that quantified hydrographic measurement of flushing is in all cases an essential element of a prima facie showing that a marina project will not cause violations of water quality standards. Notwithstanding the above noted statement of the court in 1800 Atlantic that "there is no finding of fact . . . that quantifies 'how productive the marine habitat may be' . and no record support . . . that there would be some quantifiable diminution in the quality of marine habitat attributable to [the] project," 552 So.2d 951, the court did not reject the finding that the project adversely affected the conservation of fish and wildlife, fishing or recreation values, and marine productivity. Indeed, had the court rejected the above finding due to lack of quantified findings the court would never have gone on to reach the issue of mitigation because in 1800 Atlantic mitigation could only become relevant if the applicant was unable to provide reasonable assurance that the project satisfies the public interest criteria of Section 403.918(2) (a), Florida Statutes. See Section 403.918(2)(b), Florida Statutes. I do agree that in some cases quantified hydrographic studies of flushing may be required in order to provide reasonable assurances. Thus, in Rudloe v. Dickerson Bavshore, Inc., 10 FALR 3426 (DER Case No. 87-0816, June 9, 1988), my predecessor held that a dye tracer study was necessary to provide quantitative information about dilution rates and directions on dispersion of pollutants emanating from a proposed marina site which was in "close proximity" to Class II waters approved for shellfish harvesting. 10 FALR at 3447-48. However, the need for such quantified studies must be determined on a case by case basis and is not required as a matter of law for all marinas. 5/ Far me to determine as a matter of law that experts may establish a fact only by certain types of evidence would be an unwarranted and unwise intrusion into the scientific domain of the expert. Thus, in Kralik v. Ponce Marine, Inc., 11 FALR 669, 671 (DER Final Order, Jan. 11, 1989), my predecessor held that expert testimony with regard to flushing does not lack credibility just because a hydrographic study had not been conducted. Of course, the finder of fact has the ultimate say on how much weight an expert opinion should be given if it is not based on a quantified study. Thus, whether an expert testifying on adequacy of flushing has conducted a quantifiable hydrographic study merely goes to the weight of the evidence. Kralik, 11 FALR at 671. I only conclude that a quantified hydrographic study for a proposed marina is not in all cases essential for a showing of reasonable assurances that water quality standards will not be violated. Accordingly, to the extent that the Hearing Officer's findings of fact state that a quantified hydrographic study is required in all cases as a prima facie element of a showing of reasonable assurance that a project will not violate water quality standards, I reject such statement as a mislabled and incorrect conclusion of law. Reasonable Assurance That Flushing Is Adequate To Prevent Violations of Water Quality Standards I read Speer's Exceptions Nos. 1, 3, 4, 5, 6, 7 and 8 in whole or in part as taking exception to the Hearing Officer's finding that under the facts of this case a quantified hydrographic study was needed in order to provide reasonable assurance that the project would not cause violations of water quality standards, and that because such a quantified hydrographic study had not been conducted, reasonable assurances had not been provided. (F.O.F. Nos. 33, 35, 38- 39, 40, 43-45, 64, 66 and 69) As noted by the Hearing Officer, the applicant's expert testimony concerning the adequacy of the flushing consisted of general statements describing visual observations of river and tidal flows which, together with past experience and knowledge of the general area of the project, formed the basis for the experts' opinions that a quantified hydrographic study was not necessary for this project. (R.O. at 22-23) Thus, far example, Mr. Charles C. Isiminger, accepted as an expert in marina design and hydrographic engineering testified that based on his knowledge of the area, its riverine and tidal flows, a hydrographic documentation was not needed to provide reasonable assurance that the project would not cause water quality violations. Mr. Isiminger also testified that any pollutants entering the water from the marina would be flushed out of the area within one tidal cycle. (Tr. at 65-66, 70, 77- 79, 93, 110, 125, 128, 134) Mr. Thomas Franklin, an environmental supervisor from the Department testified that: the hydrographic survey was not really necessary due to the location of the project being in open waters and in close vicinity to the Inlet with a large volume of tidal waters moving in this area, plus the fact that it was further enhanced by flushing due to the St. Lucie River being -- basically coming around Hell Gate point [sic] and funneling out into this estuary. (emphasis added) TR at 437. Other experts also testified that the area was well flushed and that a quantified hydrographic study was not needed in this case. (Jacqueline Kelly, Tr. at 187; John Meyer, Tr. at 319, 322, 341; Gerald Ward, Tr. at 44749) 6/ Speer asserts that the Hearing Officer's finding that a quantified hydrographic study is required in this case cannot stand in light of the unrebutted expert testimony that the marina site will be well flushed and that the rate of flushing provides reasonable assurances the water quality standards will not be violated. I have found no competent substantial evidence in the record which would support a finding that under the facts of this case a quantified hydrographic study is required. I did note that in Footnote 21 of the Recommended Order (R.O. at 20) the Hearing Officer states: Tidal range is only one of the types of data used to quantify flushing rates and pollutant dispersal rates. See TR at 78. Other appropriate data include: overall flow rates, mid tide flow, flow amplitude (the magnitude of the flow without regard to direction, i.e., speed as opposed to velocity), horizontal current distribution, downstream plume characteristics, and field verification using a dye tracer. All of this data is needed to fully describe and quantify flushing rates and pollutant dispersal rates. (citing testimony of Mr. Isiminger at Tr. 88-94) At first blush this may appear to be competent substantial evidence supporting a finding that a quantified hydrographic study is necessary in this case. However, when the testimony is read in its complete context, it is clear that Mr. Isiminger is testifying as to what is necessary to do a hydrographic study when one is needed, and is not testifying that such a study is needed in this case. (Tr. 88-94). I also note that the record contains a memo written by Dr. Kenneth Echternacht, a hydrographic engineer employed by the Department. (Tr. at 67-70) This memo was admitted without objection. (Tr. at 23) The memo states in part that "without . . . hydrographic documentation, reasonable assurance cannot be given that the project will not cause problems." (Tr. at 70; Pet. Exh. No. 10) 7/ Dr. Echternacht was not called as a witness at the hearing and the letter was not offered as evidence of the opinion of Dr. Echternacht or the Department at the time of the de novo hearing. To the contrary, the above noted testimony of Mr. Franklin and the testimony of Jacqueline D. Kelly, an environmental specialist of the Department accepted as an expert in evaluating impacts of environmental dredge and fill projects (Tr. at 187, 195; R.O. at 3), clearly establish that at the time of the de novo hearing the Department was of the opinion that further hydrographic documentation was not needed. The Hearing Officer noted that Mr. Meyer testified that the flushing is a "very, very complicated dynamic situation." (Tr. at 320). The testimony was as follows: Q. So you don't know for sure whether the currents here impact this at all or stay offshore from it? A. Oh, the currents definitelv affect it, and you do have interchange -- as I mentioned before, a very high rate of interchange on a daily basis on every tide. Q. Are you saying that the current that flows through here every day flows right through the site? A. We're dealing with two different things here. We're dealing with your currents, your general migration of waters from the estuary from the inland areas down. You're also dealing with tidal effects coming in and out, and it's a very, very complicated dynamic situation. For me to try to tell you exactly how these things work would be impossible without having a very, very long drawn-out expensive study done on the entire area, and I have not reviewed any studies like that. Tr. at 319-20 (emphasis added) When taken in its context it is clear that Mr. Meyer is testifying that there is a very high rate of exchange on a daily basis on every tide. The fact that he viewed the exact details of the flushing as very complicated in no way retracted his statement that there was a very high rate of exchange on every tide. My review of the record leads me to concur with Speer that no testimony, either on direct, cross-examination, or examination by the Hearing Officer, nor any other evidence was introduced to rebut the expert testimony presented by Speer and the Department that flushing on the site was adequate to provide reasonable assurance that water quality standards will not be violated. 8/ As a general rule, the trier of fact may not arbitrarily reject uncontroverted evidence as proof of a contested fact. Merrill Stevens Dry Dock Co. v. G. & J. Investments, 506 So.2d 30 (Fla. 3d DCA 1987), rev. den., 515 So.2d 229 (Fla. 1987); City of St. Petersburg v. Vinoy Park Hotel, 352 So.2d 149 (Fla. 2d DCA 1977); In Re: Estate of Hannon, 447 So.2d 1027 (Fla. 4th DCA 1984). This does not mean that a mere scintilla of unrebutted evidence is sufficient to establish a contested fact in an administrative hearing. At least in the context of administrative proceedings, the unrebutted evidence still must be competent substantial evidence to support a finding of fact. 9/ There is no suggestion that the Hearing Officer rejected the unrebutted testimony of the experts of Speer and the Department as not being competent substantial evidence. In fact, in the light of the testimony of Mr. Isiminger (Tr. at 65- 66), Mr. Ward ( Tr. at 447-449), Mr. Meyer (Tr. at 238- 239), and Mr. Franklin (Tr. at 345-350), it is beyond peradventure that there is competent substantial evidence to support a finding that flushing is adequate to provide reasonable assurance that the marina will not cause violations of water quality standards. It is clear from the context of the Recommended Order that the Hearing Officer believed that reasonable assurance had not been provided only because he believed that a quantified hydrographic study was required as a matter of law. Although I reject the Hearing Officer's conclusion that a quantified hydrographic study must be conducted as a matter of law for all marina applications, I must still determine whether a quantified hydrographic analysis is required under the facts of this case. In Rudloe v. Dickerson Bayshore, 10 FALR 3426 (DER Final Order, June 9, 1988) it was held that a hydrographic study was not adequate because it did not include a quantified dye tracer study. Id., 10 FALR at 3448. In Rudloe, as in this case, the marina was located in Class III waters, but near Class II waters. However, in Rudloe, the marina site was much closer to the Class II waters (approximately 1,700 feet in Rudloe (10 FAIR at 3430) as compared to approximately 8,000 feet in this case). (R.O. at 16, F.O.F. No. 26) Also, the Rudloe case is significantly different from this case in that competent substantial expert opinion was presented in Rudloe that the marina would adversely impact the Class II shellfish harvesting area. See Rudloe, 10 FALR at 3433-35, 3437-38 (testimony of DNR expert that operation of marina would result in closure of waters to the harvest of shellfish; testimony of Dr. Robert Livingston that the hydrographic drogue studies conducted were inadequate.) In this case, neither expert nor lay testimony was offered by Barringer to show that operation of the marina would result in violation of water quality standards or have any adverse impact on the Class II shellfish waters. 10/ I conclude that the facts of this case as found by the Hearing Officer are not sufficiently similar to the facts of Rudloe so as to justify holding as a matter of law a quantified hydrographic study is necessary to establish the required reasonable assurances. Since the record contains competent substantial evidence that flushing is adequate to provide reasonable assurance that the marina will not cause water quality violations, and since there is no competent substantial evidence in the record to support the Hearing Officer's contrary finding, I must accept the exception of Speer and reject the Hearing Officer's findings of fact to the contrary. In this case I note that I am not so much rejecting findings of fact as rejecting a conclusion of law. As I noted, the Hearing Officer's finding is really based on a conclusion of law which I reject. This leaves only unrebutted competent substantial evidence that there will be adequate flushing to provide reasonable assurance that the operation of the marina will not result in water quality violations. There is no rational basis to reject this unrebutted competent substantial evidence. Therefore, I must accept as proven that the applicant has provided the reasonable assurances that operation of the marina will not result in water quality violations. Merrill Stevens Dry Dock; City of St. Petersburg; Estate of Hannon; supra, Effect On Class II Waters Speer's Exceptions Nos. 7 and 8 take exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the marina would not have a "negative effect" an the Class II waters of the St. Lucie Inlet and the Great Pocket. (F.O.F. No. 43) Rule 17-312.080(6)(b), Fla. Admin. Code provides: The Department also shall deny a permit for dredging and filling in any class of waters where the location of the project is adjacent or in close proximity to Class II waters, unless the applicant submits a plan or proposes a procedure which demonstrates that the dredging or filling will not have a negative effect on the Class II waters and will not result in violations of water quality standards in the Class II waters. In this case expert testimony was presented by Speer and the Department that due to the distance of the marina site from the Class II waters (8,000 feet) the marina site was not in close proximity to the Class II waters, and due to the rapid flushing of the area, the construction and operation of the marina would neither have a negative effect nor would result in violations of water quality standards in the Class II waters of St. Lucie Inlet and the Great Pocket. (Isiminger, Tr. at 96, 126-27; Meyer, Tr. at 254-55) I find that the record contains no competent substantial evidence to rebut the evidence introduced by Speer and the Department that the marina will have no negative effect on Class II waters and will not result in violation of water quality standards in Class II waters. Accordingly, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersburg; In Re: Estate of Hannon; supra. Reasonable Assurance That Operation Of The Marina Will Not Result In Prop Dredging Or Violations Of The State Water Quality Criterion For Turbidity Speer's Exceptions Nos. 1, 2, 9-12, and 16 in whole or in part take exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the boat traffic from operation of the marina would not cause prop dredging or violations of the water quality criterion for turbidity. (F.O.F. Nos. 33-34, 45, 48, 52-53, 64, and 67) 11/ On one hand, there was testimony that the depths of the marina, in combination with the size of boats allowed in the various slips, would allow for a one foot clearance from the bottom of the boats to the bottom of the marina, and that this clearance, in combination with speed limits in the marina, would provide reasonable assurance that operation of the marina would not result in prop dredging or turbidity violations. (Isiminger, Tr. at 104-107, 118; Meyer Tr. at 263-65, 299, 304- 305; Kelly, Tr. at 189-190; Ward, Tr. at 460) On the other hand, Bruce Graham, admitted as an expert in marine biology testified that: "A large boat, three feet from the bottom, I think would resuspend sediment." (Graham, Tr. at 378). The Hearing Officer, noting that when asked if one foot clearance is sufficient to prevent prop dredging and resultant turbidity violations, a Department witness, testified: I would have to say that we simply don't have enough documentation to know this for a fact. We know that a foot gives us a degree of comfort that there will not be prop wash. In certain instances -- a tug boat, for instance, you know, with huge engines, you're going to have prop wash over a much -- over a large area and with probably much more than a foot of clearance. But for the normal, typical marina a foot, as I say, gives us a degree of comfort that we have settled on. Neyer, Tr. at 264. The Hearing Officer concluded that the witnesses of Speer and the Department could not explain the reasons or efficacy of the "one foot policy" except to say that in their experience the one foot policy was adequate to prevent prop dredging and turbidity violations. (R.O. at 28 n.35)0 The Hearing Officer thus found that Speer and the Department failed to "prove up" the one foot policy -- i.e., failed to elucidate and explicate the reason for the policy. 12/ Clearly the Hearing Officer placed more weight on the testimony of Mr. Bruce Graham than that of Isiminger, Meyer, Kelly and Ward. Since I cannot say that the testimony of Graham was not competent substantial evidence, I am not at liberty to reweigh the evidence or reject the Hearing Officer's finding of fact. See, Florida Dept. of Corrections v. Bradley, 510 So.2d 1122 (Fla. 1st DCA 1987); Heifetz v. Department of Business Regulation, 475 So.2d 1277, 1281 (Fla. 1st DCA 1985); Sections 120.57(1)(b)10., and 120.68(10), Florida Statutes. Speer contends that Barringer presented no evidence that prop dredging will cause sufficient turbidity to violate the state water quality turbidity criterion of 29 NTUs. 13/ That contention misses the point. The burden is on Speer to establish by the preponderance of evidence that reasonable assurance has been provided that operation of the marina will not result in violations of the water quality criterion for turbidity. Florida Department of Transportation v. J.W.C., Co., 396 So.2d 778 (Fla. 1st DCA 1981). The Hearing Officer, as the finder of fact, concluded that Speer failed to do so. Accordingly, I reject the exception of Speer and accept the Hearing Officer's finding of fact that Speer failed to provide reasonable assurance that operation of the marina would not cause prop dredging or violations of the state water quality criterion for turbidity. Manatee Impacts and the Public Interest Test Speer's Exceptions Nos. 13 and 17 take exception to the Hearing Officer's finding that Speer failed to do a quantified study of impacts to manatees and therefore failed to provide reasonable assurance that the marina will not have an adverse impact on manatees, their migratory patterns, and their habitat. (F.O.F. Nos. 61, 64 and 68) The Hearing Officer reasoned as follows: Instead of a traffic study, the Applicant and DER presented evidence in the form of general statements that manatees need not migrate north and south through the approach channel. According to the Applicant and DER, manatees can migrate across the project site by one of two alternative routes. They can migrate in one or two feet of water under moored boats and then under wave breaks on the north and east piers, or they can migrate in the shallow water landward of the west boundary of the project. That evidence was not persuasive and was controverted by competent, substantial, and persuasive evidence that manatees would be deterred from migrating under the project footprint by substantial obstacles in their path. Manatees migrating under the project footprint would be exposed to 86 or more moving boats with powerful engines and drafts of four to five feet in waters covering approximately 20,800 square feet. It could be argued, or course, that 86 or more boats would not be moving in and out of the marina at one time. However, it is impossible to estimate occupancy rates, length of stay, and frequency of boat trips without a traffic study. (R.O. at 35, n. 51) As Speer's exception notes, there was testimony that because of the width of the river and boat speed restrictions in the project area, there would be no adverse impacts an the manatee from the marina. (Kelly, Tr. at 162; Meyer, Tr. at 255-56, 331- 32; Isiminger, Tr. at 130) The St. Lucie/Jupiter/Hobe Sound waterways are a major travel corridor for manatees. (DER Exh. No. 4) Between 1974 and December 1990, there were ten water craft related manatee fatalities within the boating sphere of influence of the project. (DER Exh. No. 4) In order to reduce impacts on the manatees, the proposed permit contains the following specific conditions: S.C. No. 13: The permittee agrees to install and maintain a minimum of one manatee education/display on the main access pier during and after construction. S.C. No. 15: The permittee agrees that any collision with a manatee shall be reported immediately [to DNR and U.S. Fish and wildlife Service]. S.C. No. 18: The permittee shall post four (4) manatee area/slow speed signs, two of which would be spaced along the perimeter pier and two of which would be located on the outside of the marina for all boating traffic to observe within the marina facility. (DER Exh. No. 3) 14/ There was testimony that the piers, once constructed, would not impair the passage of manatees. (Isiminger, Tr. at 114- 115) On the other hand, there was some testimony that manatees may have to go around the project rather than through it. (Meyer, Tr. at 311) The existing boat traffic past the site of the project to the Inlet was "rough1y estimated" at 50 to 100 boats a day. (Meyer, Tr. at 337) The U.S. Fish and Wildlife Service determined that "while [the project] may negatively affect, it is not likely to jeopardize the continued existence of the West Indian Manatee." (Tr. at 120-21) The Hearing Officer concluded that reasonable assurance as to adverse impacts on manatees could not be provided absent a quantified traffic study. (R.O. at 35, n. 51) In Coscan Florida, Inc. v. Department of Environmental Regulation, 12 FAIR 1359 (DER Final Order March 9, 1990), the Department held that the information needed to determine a marina's impact on manatees and the necessary actions to mitigate such impacts must be decided an a case by case basis. For example, in Sheridan v. Deep Lagoon Marina, 11 FALR 4710 (DER Final Order, Aug. 24, 1989), 15/ a marina sought to expand by adding 113 new wet slips. The marina was required to develop a manatee protection plan far the surrounding portions of the Caloosahatchee River, all new slips were limited to sail boats until the manatee protection plan was implemented and enforced, and power boat occupancy was limited to 75% of the total 174 wetslips in any event. The marina also made available a wet slip for use by the Florida Marine Patrol. In this case there is evidence of significant boat related manatee fatalities in the boating sphere of influence of the proposed marina. There is also evidence of existing traffic of 50-100 boats per day past the project site. In view of the fact that this project would add 86 slips and a public fueling facility, it seems likely that that the project will significantly increase both boat traffic and the threat of manatee collisions. Accordingly, I concur with the Hearing Officer that there is competent substantial evidence to support a finding that further studies are needed to determine what, if any, additional manatee protection conditions are needed to provide reasonable assurance that manatees will not be adversely affected. I conclude that the applicant did not provide reasonable assurance that the operation of the marina will not have an adverse impact on manatees, their migratory patterns, and their habitat, and therefore failed to provide reasonable assurance that the project is not contrary to the public interest. Therefore, I reject the exception of Speer. Cumulative and Secondary Impacts Speer's Exception No. 15 takes exception to the Hearing Officer's finding that the applicant failed to provide reasonable assurance that there will be no adverse cumulative pacts created either by the cumulative effects of the object and existing similar projects, or by secondary pacts of the project itself. (F.O.F. No. 66) 16/ Cumulative impact analysis takes into consideration the cumulative impacts of similar projects which are existing, under construction, or reasonably expected in the future. Conservancy v. A. Vernon Allen Builder, supra; Section 403.919, Florida Statutes. Secondary impact analysis considers the impact of the project itself and of any other relevant activities that are very closely linked or causally related to the permitted project. Conservancy, 580 So.2d at 778; J.T. McCormick v. City of Jacksonville, 12 FALR 960, 980. 17/ Thus, in Conservancy the secondary impact analysis was required to consider the environmental impacts of development of 75 estate homes on an island where the development would be reasonably expected as a result of the permitted laying of a subaqueous sewer line. Similarly, in del Campo v. Department of Environmental Regulation, 452 So.2d 1004 (Fla. 1st DCA 1984), the Department was required to consider the environmental impacts of the foreseeable development of an island facilitated by the permitted building of a bridge to the island. In this case there is competent substantial evidence that there are other marinas located 1,750 feet downstream in Willoughby Creek, and 5,000 feet downstream in Manatee Pocket. (R.O. F.O.F. 31; Isiminger, Tr. at 112; Meyer, Tr. at 261) The record contains competent substantial evidence that the cumulative impact of the project and the existing marinas in Willoughby Creek and Manatee Pocket will not result in violations of state water policy. (Isiminger, Tr. at 125; Kelly, Tr. at 167) I cannot say that the testimony of Isiminger and Kelly on cumulative impacts is not competent, substantial evidence. In light of the fact that there is no competent substantial evidence to indicate that cumulative impacts would result in water quality violations, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersbur; In re: Estate of Hannon; supra. As to secondary impacts, the Hearing Officer pointed out that Speer did not introduce any evidence as to whether there would be secondary impacts to water quality as the result of further development or increased utilization of the uplands facilities. (See F.O.F. 66, n.59, R.O. at 39) Such further development or increased utilization of upland facilities is reasonably foreseeable and would be very closely linked or causally related to the building of an 86 slip marina with public fuel services. As noted above, the applicant has the burden of providing reasonable assurances as to cumulative and secondary impacts. Brown v. DER, supra; Conservancy, supra. However, neither the pleadings nor the pre-hearing stipulation raised the issue of the adequacy of the secondary impact analysis. In a case such as this where the Department's notice of intent to issue a permit has been challenged by a third party, the applicant's prima facie case need only include the application and the accompanying documentation and information relied on by the Department as the basis of its intent to issue. Florida Department of Transportation v. J.W.C., 396 So.2d 778, 788 (Fla. 1st DCA 1981). The petitioner challenging the permit must identify the areas of controversy and allege a factual basis for its contentions that the applicant did not provide the necessary reasonable assurances. J.W.C., 396 So.2d at 789. See also Woodholly Assoc. v. Department of Natural Resources, 451 So.2d 1002, 1004 (Fla. 1st DCA 1984). Since Barringer did not identify this issue and did not allege any factual basis for a contention that the secondary impact analysis was inadequate or incorrect, I may not rule on the issue in this order. Miscellaneous Exceptions To Findings of Fact Speer's Exception No. 14 takes exception to the Hearing Officer's finding that Speer failed to provide reasonable assurance that the project will have no adverse impact on (1) the relative value of functions being performed by areas affected by the project, including seagrasses, shell fish, and fin-fish, and (2) recreational and commercial values in the vicinity. (F.O.F. No. 64) Speer contends that this finding is not supported in the record by competent substantial evidence and is contrary to unrebutted testimony of Ms. Kelly and Mr. Isiminger. (Kelly, Tr. at 159, 161-62, 165-67; Isiminger, Tr. at 73) I cannot say that the testimony of Isiminger and Kelly is not competent, substantial evidence, and I find no evidence in the record to rebut the testimony of Kelly and Isiminger. Therefore, I must accept Speer's exception and reject the Hearing Officer's finding. Merrill Stevens Dry Dock; City of St. Petersburg; In re: Estate of Hannon; supra. Speer's Exception No. 3 takes exception to the Hearing Officer's finding that Speer failed to provide a current water quality analysis. (F.O.F. No. 35) A water quality analysis was submitted in April of 1990, shortly after the permit application was filed. (R.O. at 2, 19; F.O.F. No. 34) I find no competent substantial evidence in the record to suggest any reason for believing that the water quality has changed since April of 1990. I agree with Speer that, absent some specific reason for believing that the water quality has changed since the date of a study conducted contemporaneously with the permit application, there is no requirement to provide an updated water quality analysis. RULINGS ON EXCEPTIONS TO CONCLUSIONS OF LAW Need For Quantified Hydrographic Study Speer's Exceptions Nos. 1, 7 and 9, in whole or in part, take exception to the Hearing Officer's conclusions of law that a quantified hydrographic study was needed to provide reasonable assurances that the operation of the marina would not result in violations of water quality standards and would would not have a negative effect on Class II waters. For the reasons stated in Parts III(1), (2) and (3) above, I accept this exception and reject the above noted conclusions of law. Introduction Of Issues Not Set Forth In Pleadings Or Pre-Hearing Stipulations Speer's Exceptions Nos. 1, 2, 3, and 5, in whole or in part, take exception to the Hearing Officer's consideration of issues of (1) the need for a quantified hydrographic study, (2) the proximity of the site to Class II waters, (3) turbidity and prop dredging, (4) cumulative impacts, and (5) the need for a quantified study on manatee impacts. For the reasons set forth in Part 111(6) above, I agree that, absent waiver, a petitioner challenging an intent to issue a permit may not raise issues at the hearing which were not raised in the pleadings or pre-hearing stipulations. However, in this case the issue of manatee impacts was raised in the pleadings, and Speer was on notice that it had the burden of proof on that issue. As to the other issues, even if I accepted far the sake of argument that they were not raised in the pleadings or pre-hearing stipulations, Speer failed to timely object to the raising of these issues at the hearing and therefore waived any objection. See Sarasota County and Midnight Pass Society v. Department of Environmental Regulation, 13 FAIR 1727 (DER Final Order, April 4, 1991). Therefore, I reject the above exceptions. Proximity To Class II Waters Speer's Exception No. 2 takes exception to the Hearing Officer's conclusion of law that Speer was required to submit a plan which demonstrated that the marina would not have a negative effect on Class II waters. (C.O.L. Nos. 12 and 13) I do not agree that where a proposed marina site is 8,000 feet from Class II waters and where the site is rapidly flushed as noted in Parts 111(1), (2) and (3) above, that the site is in close proximity with the Class II waters within the meaning of Rule 17-312.080(6), Fla. Admin. Code. Accordingly, I accept this exception and reject the above note conclusion of law. Public Interest Test Speer's Exception No. 4 takes exception to the Hearing Officer's conclusion of law that Speer failed to provide reasonable assurance that the project was not contrary to the public interest. (C.O.L. Nos. 17 and 20) For the reasons set forth in Parts III(4) and (5) above, I reject this exception. Cumulative Impacts Speer's Exception No. 5 takes exception to the Hearing Officer's conclusion of law that Speer failed to provide reasonable assurances that cumulative impacts would not result in water quality violations, and that such assurances could only be provided by a quantified study. For the reasons set forth in Parts III (1), (2), (3) and (6) above, I accept this exception and reject the above noted conclusions of law. Modification Of Permit Conditions Speer's Exception No. 6 takes Exception to the Hearing Officer's conclusions of law Nos. 24-34. These conclusions of law concern questions of the authority of the Hearing Officer and me to modify the conditions of the permit. I agree with Speer that since none of the parties have requested any modifications, these conclusions of law are irrelevant. 18/ Therefore I accept the exception and reject the above noted conclusions of law as irrelevant. Miscellaneous Speer's Exception No. 8 in part takes exception to the Hearing Officer's conclusion that Speer and the Department failed to provide reasonable assurance as to prop dredging and turbidity violations because neither Speer nor the Department sufficiently proved the basis for the one-foot clearance policy. For the reasons set forth in Part III(4) above, I reject this exception. Speer's Exception No. 8 in part takes exception to the Hearing Officer's conclusion that the question of whether mitigation is adequate is a question of law. I agree with the Hearing Officer and reject this exception. See 1800 Atlantic Developers v. Department of Environmental Regulation, 552 So.2d 946, 955 (Fla. 1st DCA 1989).
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is recommended that Respondent, Department of Environmental Regulation, enter a Final Order denying the application for a permit to construct the proposed project and denying the request for determination of improper purposes. RECOMMENDED in Tallahassee, Leon County, Florida, this 16th day of June, 1992. DANIEL MANRY Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399 1550 (904) 488 Filed with the Clerk of the Division of Administrative Hearings this 16th day of June, 1992.
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.

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. "Pollution" shall be as defined in subsection 502(19) of the CWA and subsection 403.031(2), F.S.

"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.

"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. Sample Are listed if they Sizes have at least this # of exceedances From To 10 15 3 16 23 4 24 31 5 32 39 6 40 47 7 48 56 8 57 65 9 66 73 10 74 82 11 83 91 12 92 100 13 101 109 14 110 118 15 119 126 16 127 136 17 137 145 18 146 154 19 155 163 20 164 172 21 173 181 22 182 190 23 191 199 24 200 208 25 209 218 26 219 227 27 228 236 28 237 245 29 246 255 30 256 264 31 265 273 32 274 282 33 283 292 34 293 301 35 302 310 36 311 320 37 321 329 38 330 338 39 339 348 40 349 357 41 358 367 42 368 376 43 377 385 44 386 395 45 396 404 46 405 414 47 415 423 48 424 432 49 433 442 50 443 451 51 452 461 52 462 470 53 471 480 54 481 489 55 490 499 56 500 500 57 The "calculations [reflected in Table 1] are correct." 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.

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

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

The Issue This cause concerns a dispute between the Petitioner and the Respondents concerning whether a permit ("dredge and fill") and water-quality certification should be issued by the Respondent, Department of Environmental Regulation (hereinafter referred to as "Department" or "DER"), authorizing the construction of a private dock with terminal deck and platform, in conjunction with the construction of a 250-foot "privacy fence" in the adjacent salt marsh, and whether construction, installation and operation of the facility will violate State water-quality standards and the public-interest standards embodied in Section 403.918, Florida Statutes.
Findings Of Fact LaRae Hays, the Respondent/applicant, owns real property to be used for residential purposes, which adjoins a salt marsh and tidal creek contiguous to the Nassau River in Duval County, Florida. The Respondent/applicant applied for a permit and water-quality certification so as to authorize the construction of a private dock with a terminal deck and "stepdown" platform. The applicant also seeks authority to construct a 250-foot by 8-foot wooden ??privacy fence", parallel to that dock. The structures are to be built on a tidal creek and within a salt marsh contiguous to the Nassau River. The application is opposed by the Petitioner, who is an adjoining property owner. The Petitioner opposes the application for the reasons referenced in the above Preliminary Statement. The Department is an agency of the State of Florida charged with regulating and permitting activities which may be sources of pollution, such as the instant project, which are constructed, operated or installed in waters of the State, as defined in Chapter 403, Florida Statutes, and Title 17, Florida Administrative Code. The Department is charged, as pertinent hereto, with reviewing applications, such as the subject application, to insure that the water-quality standards and public-interest standards embodied in Section 403.918, Florida Statutes, as well as Chapters 17-3 and 17-312, Florida Administrative Code, are complied with before issuing a permit authorizing the construction of the proposed facility. Mr. Tyler was called as the first witness for the Department. The parties stipulated that the Department could put on its case first in the order of proof. Mr. Tyler was accepted as an expert witness in the field of the "impact of dredge and fill projects on the environment~?. It was thus established that the Respondent/applicant's project is proposed for a piece of property in the adjacent salt marsh on Black Hammock Island in Duval County, Florida. The Respondent/applicant proposes to construct a private dock, 184 feet by 4 feet, with a 12-foot by 12-foot terminal deck and a 12-foot by 5-foot "stepdown" platform. A portion of the dock is already constructed and is included in the permit sought. The deck is proposed to be surrounded on three sides with a six-foot-high lattice wall covered with a pitched roof. During the course of the proceeding, however, the Respondent/applicant conceded that she would abandon the proposal to construct the lattice walls, would rather leave the terminal deck and roofed area open so that the neighbors' view of the salt marsh and river would not be obstructed and that she would rather install blinds which can be raised or lowered for the roofed portion of the proposed terminal deck. The Respondent/applicant previously dredged and placed fill on a portion of the wetlands in question and dredged a drainage ditch along the perimeter of the wetlands and the Respondent/applicant1s property. The fill was for the purpose of creating a sort of "causeway" leading from the upland property owned by the Respondent/applicant to the landward extent of the already-existing dock. Pursuant to informal enforcement action by the Department, the Respondent/applicant agreed to, and has, removed that fill material and corrected, or is about to correct, the dredging activity done without permit in the drainage ditch in question. The proposed project is located in Class II waters, classified as "conditionally approved" for shellfish harvesting. Normally, under the provisions of Rule 17-312.080(7), Florida Administrative Code, a dredge and fill permit for the proposed project and its construction could not be authorized in such Class II shellfish harvesting waters. However, the Department has granted a variance from that rule so that the activity sought to be permitted can be authorized as a result of the instant permit application, by its notice of intent to grant the variance entered on June 5, 1990. That variance became embodied in a Final Order of the Department authorizing it, entered on July 31, 1990. No interested party responded to due and appropriate notice of the intent to grant the variance, hence, the Final Order approving it. The variance was accompanied by mandatory conditions involving the protection of historical or archaeological artifacts, the prohibition of more than two boats being moored at the dock; of any overboard discharges of trash, animal or human waste or fuel; against any non-water dependent structure such as gazebos or fish-cleaning stations, which must be located on the uplands and against boat shelters having enclosed sides. Additional conditions were that any dock over grass beds should be constructed as to allow for maximum light penetration and that water depth at the mooring area for the dock shall be sufficient to prevent bottom scouring by boat propellers. Additionally, in the notice of intent to grant document, the Department has required that in order for the permit at issue to be granted, in addition to the general conditions applicable to any such permit, the following specific conditions shall be observed by the Respondent/applicant during and after construction: Historical and archeological artifacts shall be reported to the Department, as well as the Bureau of Historic Preservation, Division of Archives History and Records; Prior to commencement of the work, the permittee shall provide written notification of commencement to the Department; turbidity control shall be utilized throughout the project to contain any turbidity generated; The waterward end of the dock shall be marked by a sufficient number of reflectors as to be visible from the water at night by reflected light; All work shall be done during periods of average or low water in order to minimize turbidity; All disturbed areas shall be re-vegetated with indigenous vegetation in order to prevent erosion or unstabilized material entering into State waters; and Finally, that the project shall comply with applicable State water- quality standards. The Respondent/applicant has agreed to these conditions. Moreover, the testimony of Mr. Tyler establishes that no water-quality violations of the standards contained in Chapter 17-312 and 17-3, Florida Administrative Code, will be occasioned by the construction or operation of this facility. The pilings necessary to perform the construction involved will be installed at periods of low or average tide, such that the installation area will not generate turbidity in the State waters involved at the site. The dock is so designed that maximum light penetration will occur so that deleterious shading of the marsh grasses involved at the site and under the footprint of the dock will not occur. Moreover, the dock and the proposed fence, for that matter, would have a beneficial effect on benthic species diversity by encouraging aquatic invertebrates to attach and form colonies on the posts and pilings where they enter State waters. It was also established, through the Department's evidence, as well as the testimony of the Respondent/applicant's witnesses, that there is a sufficient water depth in the creek located at the waterward end of the proposed dock and ~?stepdown?? platform, such that the small boats which would be able to navigate the creek, being of sufficient shallow draft, will not occasion propeller scouring or propeller-generated turbidity when operated at prevailing water depths for boats which will be moored at the end of the proposed facility. In summary, it has been demonstrated that no State water-quality standards will be violated by the installation and operation of the proposed facility, given the conditions which the Respondent/applicant and the Department have already agreed upon and the Respondent/applicant has accepted on the record in this case, including the condition concerning no gazebo-type structures located on the dock and no fish cleaning facilities or fueling equipment or facilities on the dock or platforms. Such conditions should be incorporated in any Final Order and permit resulting from this proceeding. In addition to the water-quality considerations discussed above, it must be determined whether reasonable assurances have been provided by the permit applicant that the proposed project will meet the "public interest" standards of Section 403.918(2)(a)1-7, Florida Statutes. In this regard, it has been demonstrated by the evidence and testimony adduced by the Respondent/applicant and the Department that the project will not adversely affect the public health, safety or welfare or the property of others in the context of the various environmental concerns addressed and regulated by Chapter 403, Florida Statutes, and Title 17, Florida Administrative Code. The unrefuted testimony of expert witness, Tyler, establishes that the project will not adversely affect the conservation of fish and wildlife, including endangered or threatened species or their habitats. The project will not adversely affect navigation, the flow of water, or cause harmful erosion or shoaling. Mr. Tyler's testimony establishes that the ecosystem in the vicinity of the project consists of a natural intertidal saltwater marsh, which is currently in excellent condition and has a high relative value of functions as a habitat and nursery area for marine and estuarine vertebrate and invertebrate species. The project will not adversely affect fishing or marine productivity in the area involved nor have an adverse effect on the current condition and relative functional value of the marsh area in terms of habitat for, and the conservation of, fish and wildlife and in terms of its value as a marine and estuarine habitat and the marsh system's function in protecting water quality. Although the project will not adversely affect fishing or marine productivity in the vicinity of the project, the proposed "privacy fence" has not been shown to be "not contrary to the public interest'1 in terms of adverse effect on recreational values??. The "privacy fence" will not pose any of the other adverse consequences in terms of the above-discussed seven (7) public- interest standards nor will it impose a detrimental impact on water quality, especially since it will be elevated approximately a foot above the surface of the soil in the marsh area, preventing any impediment to normal tidal flows and flushing. The fence will, however, impose a detrimental effect on the recreational value of the State waters involved in the subject marshland area by impeding the aesthetic qualities of the view of the marshland and river system for adjoining landowners, specifically, the Petitioner. The fence will clearly impede this "passive recreational value" and reasonable assurances that it will not do so have not been provided in the testimony and evidence of record. The desire of the Respondent/applicant to install the fence is certainly understandable in view of the hostile relations between the Respondent/applicant and the Petitioner, caused to a great degree by the Petitioner's persistence in installing and operating an overly-bright nighttime security light and, more particularly, because of the Petitioner's habit of constantly photographing, with a video camera, the Respondent/applicants or her invitees while they are using the present dock. Because the fence will impede the recreational value of the marshland in terms of the aesthetic nature of the view of the marsh of the Petitioner, the permit should not include authorization for installation of the fence. The relevant and more peripheral facts established in this record prove the wisdom of the words of the poet, Robert Frost, who wrote that "good fences make good neighbors". The parties' dispute concerning the use of the security light and video camera more properly sounds in the circuit court, however. A proceeding involving disputed environmental permitting issues cannot serve to resolve all the "life management" disputes between the parties. In summary, the unrefuted evidence of record demonstrates that, with the exception of the last above mentioned consideration concerning the proposed fence, that the water quality standards and the public interest standards embodied in Section 403.918(1) and (2), Florida Statutes, will not be violated by the proposed project if the conditions mentioned above and those provided for in the Department's Exhibit 3, which are incorporated in these findings of fact by reference, are imposed on any grant of a permit. A grant of the permit should also be conditioned upon periodic monitoring of the installation of the proposed project, which the Department has agreed in this record to do.
Recommendation Accordingly, in view of the above findings of fact and conclusions of law it is, therefore RECOMMENDED that a Final Order be issued by the Department of Environmental Regulation granting the subject dredge and fill permit and water quality certification sought by the applicants provided that grant of the subject permit should include the general and specific conditions incorporated in the Department's Exhibit 3, as well as the conditions found to be necessary in the above findings of fact.

The Issue The issue is whether Respondent HBJ Investments, Inc. is entitled to an environmental resource permit to facilitate the construction of the Betty Jones Spa on property adjacent to property owned by Petitioner.
Findings Of Fact On November 17, 1998, Respondent HBJ Investments, Inc. (Applicant) filed an application (Application) with the South Florida Water Management District (District) for an environmental resource permit (ERP). The Application is for a Standard General (minor systems) ERP. The Application states that the proposed surface water management system is to serve a 11,564 square foot health spa with associated infrastructure improvements, such as parking, utilities, landscaping, and a stormwater detention facility. Section H of the Application responds to form questions that are intended to determine whether an application meets the requirements of a standard general ERP for a minor surface water system. Among the threshold requirements is that the proposed discharges from the site "will meet State water quality standards, and the surface water management system will meet the applicable technical criteria for stormwater management in the Basis of Review." Another threshold requirement is that the proposed activities will not cause significant adverse impacts individually or cumulatively. The Application states that the water quality treatment system will be on-line detention with effluent filtration. The Application and related documents describe the system in greater detail. The system consists of drains, inlets, a swale, an underground vault to provide effluent filtration through a sand filter and perforated pipe, an internal oil and grease skimmer, a control box, and a 15-inch diameter reinforced concrete pipe providing outfall from the vault. By Notice of Final Agency Action for Approval dated February 4, 1999, the District proposed the issuance of a "Standard General for Minor Surface Water Management Systems" ERP for the construction, operation, and maintenance of the proposed system (Permit). Permit Specific Condition 2 requires: "The discharges from this system shall meet state water quality standards as set forth in Chapter 62-302 and Rule 62-4.242, F.A.C., for class waters equivalent to the receiving waters." Permit Specific Condition 8 requires, for vault systems, that the system become dry within 72 hours after a rainfall event. Permit Specific Condition 9 requires the operation and maintenance entity to submit inspection reports for inspections to be performed every 18 months. Permit Specific Condition 10 requires a water quality monitoring program for systems, such as the proposed system, using an internal oil and grease skimmer. This condition obligates HBJ to take three samples during each of the first two annual rainy seasons following the commencement of operation of the system. The monitoring must take place immediately after rainfall events of sufficient magnitude to cause a discharge from the outfall structure. If the discharged water does not meet water quality standards for oil and grease, as established by Rule 62.302.510(3)(k), Florida Administrative Code, then the permittee must alter the system to attain compliance for this water quality parameter. The subject parcel is bounded by Fourth Avenue South on the north, First Street South on the east, Second Street South on the west, and an unnamed alley on the south. This site is just south of Al Lang Field. In its present state, the parcel is nearly entirely pervious surface. Some of the stormwater flowing onto the parcel percolates into the soils, and the remainder flows into City of Saint Petersburg stormwater sewers, from which it is carried about two city blocks to Tampa Bay, where it is discharged. The parcel was formerly used for single-family residential housing, but is now mostly cleared. The runoff from the site presently carries mostly sediments. After the proposed construction, 79 percent of the parcel would consist of impervious surface. Although small areas of the developed parcel might remain vegetated, and thus add nutrients into the runoff, the primary change in the runoff will consist of the addition of automobile-related contaminants, including, but not limited to, oil and grease. HBJ's engineer designed the proposed surface water management system to treat the first one-half inch of stormwater runoff. The engineer's report notes, in a letter dated November 13, 1998, that siltation in the vault reduces storage volume, so it is "required that cleaning be done every six (6) months." The report suggests the removal of grass clippings from the parking area, so that they are not transported to the retention vault. The report suggests that the underdrain system should be backflushed periodically, and the control structure should be checked monthly and all debris cleared. In general, the system would collect runoff from the roof downspouts and parking area. The system would provide treatment of the first 1/2 inch of runoff by capturing it in the vault, where it would filter through a layer of several cubic feet of sand before entering a perforated pipe leading to the City stormwater sewer. Runoff from rainfall in excess of the first 1/2 inch would receive little, if any, treatment. It is implicit that the first 1/2 inch of rainfall contains the first flush of contaminants from impervious surfaces. Nothing in the record specifies the efficacy of treatment provided by this standard, although it obviously is less than 100 percent efficient because of the higher standard imposed upon systems discharging into Outstanding Florida Waters (OFW). However, a pre- and post-development analysis of the runoff from the subject parcel would reveal an unknown additional volume of runoff from the developed site, due to the replacement of pervious surface with impervious surface. It is unclear whether the developed site would generate a reduced volume of sediments in this increased volume of runoff. Although little vegetated surface would exist post-development, the record does not reveal the extent to which the pre-development pervious area fails to capture the sediments prior to their entering the City stormwater system. More problematic are the automobile-related contaminants, such as oil and grease, that will be introduced into the runoff by the developed site. Presumably, the runoff from the undeveloped site contains few, if any, such contaminants. Thus, any automobile-related contaminants discharged from the surface water management system would likely be an increase from the amount of such contaminants presently discharged from the site. The runoff from the developed site would enter the City of Saint Petersburg stormwater sewer system and would be released in the nearby Tampa Bay. The record does not disclose the stormwater sewer line transporting the discharge, nor the outfall of the line into Tampa Bay. By stipulation, the parties agreed that Tampa Bay is an OFW and that discharge from the developed site would enter the City of Saint Petersburg stormwater sewer system. Tampa Bay is classified as Class II waters, which are approved for shellfish harvesting. The record does not disclose the point of discharge of the City stormwater line that would receive discharge from the developed site. However, the proximity of the site to Tampa Bay strongly suggests that the outfall would be in Tampa Bay, and it is only slightly less probable that the outfall would be at a point in the bay in the immediate vicinity of the site. The record suggests that the waters of Tampa Bay likely to receive the discharge from the site are impaired. For example, water quality conditions mandated the closing of "Lower Tampa Bay" to shellfish harvesting, for an unstated period of time, effective at sunset on July 5, 1999. Also, the Department of Environmental Protection listed two bayous in the immediate vicinity of the site as noncompliant with federal water quality standards due to excessive coliform bacteria counts and nutrients and insufficient levels of dissolved oxygen. The Basis of Review (BOR) is a document adopted by the District. It contains specific "criteria" for permitting. However, as BOR Section 1.3 explains, the goal of these criteria is to meet District water resource objectives, and the criteria are "flexible." Alternative methods of meeting "overall objectives" may be acceptable, depending upon the "magnitude of specific or cumulative impacts." The criteria, which are flexible, are the means by which the District assures that it meets its objectives, which are not flexible. BOR Section 3.1.0 recognizes that "a wide array of biological, physical and chemical factors affect the functioning of any wetland or other surface water community. Maintenance of water quality standards in applicable wetlands and other surface waters is critical to their ability to provide many of these functions." BOR Section 3.1.0 elaborates: "It is the intent of the Governing Board [of the District] that the criteria in subsections 3.2 through 3.2.8 be implemented in a manner which achieves a programmatic goal and a project permitting goal of no net loss of wetlands or other surface water functions." BOR Section 3.1.1 requires that an applicant provide "reasonable assurance" of several things. BOR Section 3.1.1(a) requires that "a regulated activity will not adversely impact the value of functions provided to fish, wildlife and listed species, including aquatic and wetland dependent species, by wetlands and other surface waters and other water related resources of the District. (paragraph 40D-4.301(1)(d), F.A.C.) (see subsection 3.2.2)." BOR Section 3.1.1(c) provides that: a regulated activity will not adversely affect the quality of receiving waters such that the water quality standards set forth in Chapters 62-3, 62-4, 62-302, 62-520, 62-522 and 62-550, F.A.C., including any antidegradation provisions of Sections 62-4.242(1)(a) and (b), 62-4.242(2) and (3), and 62-302.300 and any special standards for Outstanding Florida Waters . . . set forth in sections 62-4.242(2) and (3), F.A.C., will be violated (paragraph 40D-4.301(1)(e), F.A.C.). BOR Section 3.1.1(d) provides that "a regulated activity . . . located in close proximity to Class II waters . . . will comply with the additional criteria in subsection 3.2.5 (paragraph 40D-4.302(1)(c), F.A.C.)." BOR Section 3.1.l(f) provides that "a regulated activity will not cause adverse secondary impacts to the water resources (paragraph 40D-4.301(1)(f), F.A.C.) (see subsection 3.2.7)." BOR Section 3.1.1(g) provides that "a regulated activity will not cause adverse cumulative impacts upon wetlands and other surface waters . . . (paragraph 40D-4.302(1)(b), F.A.C.) (see subsection 3.2.8)." BOR Section 3.2.4 provides that an applicant must provide "reasonable assurance that the regulated activity will not violate water quality standards in areas where water quality standards apply. . . . The following requirements are in addition to the water quality requirements found in Chapter 5." BOR Section 3.2.4.2(c) provides that the applicant must address the long-term water quality impacts of a proposed system, including "prevention of any discharge or release of pollutants from the system that will cause water quality standards to be violated." BOR Section 3.2.5 provides: The special value and importance of shellfish harvesting waters to Florida's economy as existing or potential sites of commercial and recreational shellfish harvesting and as a nursery area for fish and shell fish is recognized by the District. In accordance with section 3.1.1.(d), the District shall: (b) deny a permit for a regulated activity in any class of waters where the location of the system is adjacent or in close proximity to Class II waters, unless the applicant submits a plan or proposes a procedure which demonstrates that the regulated activity will not have a negative effect on the Class II waters and will not result in violations of water quality standards in the Class II waters. BOR Section 3.2.7 provides that an applicant must provide "reasonable assurance" that "a regulated activity will not cause adverse secondary impacts to the water resource" as described in this section. However, this section explicitly disregards negligible or remotely related secondary impacts. BOR Section 3.2.8 provides that an applicant must provide "reasonable assurance" that "a regulated activity will not cause unacceptable cumulative impacts upon wetlands and other surface waters " BOR Section 4.2 limits off-site discharge "to amounts which will not cause adverse off-site impacts." For a proposed activity within an open drainage basin, as is the subject proposed activity, the allowable discharge is (presumably the greatest of) any amount determined in previous District permits, the legally allowable discharge at the time of the permit application, or historic discharge. Historic discharge is the peak rate at which runoff leaves a parcel of land by gravity under existing site conditions. BOR Section 5.1 requires that proposed discharges meet applicable state water quality standards. This chapter of the BOR requires that proposed systems satisfy certain quantitative criteria, depending on the type of water treatment system. However, BOR Section 5.1 warns: in certain instances a design meeting those standards may not result in compliance with the state water quality standards referenced above. Unless an applicant has provided reasonable assurance that a design will not cause or contribute to a violation of state water quality standards, the District may apply more stringent design and performance standards than are otherwise required by this chapter. Projects designed to the criteria found in this section shall be presumed to provide reasonable assurance of compliance with the state water quality standards referenced above. . . . BOR Section 5.2 sets quantitative criteria for various types of surface water management systems. The subject system is a detention, on-line treatment system. BOR Section 1.7.5 defines "detention" as the "delay of storm runoff prior to discharge into receiving waters." BOR Section 1.7.28 defines "on-line treatment system" as a "dual purpose system that collects project runoff for both water quality and water quantity requirements. Water quality volumes are recovered through percolation and evaporation while water quantity volumes are recovered through a combination of percolation, evaporation, and surface discharge." BOR Section 5.2.b applies to "[d]etention with effluent filtration system (manmade underdrains)." BOR Section 5.2.b.1 provides that proposed activities draining less than 100 acres "shall treat the runoff from . . . the first one-half inch runoff." BOR Section 5.2.b.6 adds: "Maintenance of filter includes proper disposal of spent filter material." BOR Section 5.2.c applies to "on-line treatment system[s]." This section also requires the treatment of the first one-half inch of runoff. However, BOR Section 5.2.e provides: Projects discharging directly into Outstanding Florida Waters (OFW) shall be required to provide treatment for a volume 50 percent more than required for the selected treatment system . . .. Applicant has provided reasonable assurance that the proposed surface water management system would not cause adverse water quantity impacts to receiving waters and adjacent lands and would not cause flooding. In terms of water quantity, the proposed system is designed to meet the requirements of the ten-year storm. The subject site is a short distance from Tampa Bay, and, as already noted, it is very likely that the runoff discharges into Tampa Bay at a location not far from the subject site. Thus, water quantity and flooding are irrelevant to this case. However, Applicant has not provided reasonable assurance that the proposed surface water management system would not cause adverse impacts to the value of functions provided to fish and wildlife by nonwetland surface waters and would not adversely affect the quality of receiving waters. The receiving waters of the discharge from the subject site are Class II waters that are OFW. However, these waters are also impaired sufficiently as to be in violation of certain federal water quality standards and to require the closure, at least at times, of shellfish harvesting. There are three deficiencies in the proposed permit. First, it does not specify, in clear and enforceable language, an inspection and maintenance program, which includes the undertaking by the Applicant to backwash the system at specified intervals, to replace the sand filtration medium at specified intervals, to dispose of the sand filtration medium so that the captured contaminants do not reenter waters of the state, to monitor the water discharged from the oil and grease skimmer at specified intervals following the first two years' monitoring, and generally to take any necessary action to correct deficiencies uncovered from inspections. Second, the treatment of the first 1/2 inch of runoff is insufficient for the system, which is discharging directly into an OFW. BOR Section 5.2.e raises this standard to 3/4 inch. Direct discharges requires the identification of the first receiving waters. Receiving waters are waters of the state that are classifiable as Class I-V waters. Receiving waters thus do not include waters in a stormwater sewer pipe, which are not waters of the state nor are they classifiable. Water quality determinations often require comparison of the quality of the discharged water with quality of the receiving waters. The off-site piping of the discharged water does not preclude such comparison. In such case, the analysis extends to the first receiving waters into which the pipe empties. The District's argument to the contrary invites circumvention of those provisions enacted and promulgated for the protection of OFWs. For example, several owners of land abutting an OFW could establish a jointly owned stormwater sewer line so that the point of comparison for their discharge would be the waters in the pipe rather than the OFW. Third, Applicant failed to submit a plan or propose a procedure demonstrating that the proposed activity would not have a negative effect on the Class II waters of Tampa Bay and would not result in violations of water quality standards in these Class II waters. The District failed to determine the outfall of the discharge from the subject site, so it failed to enforce the requirement of the plan required by BOR 3.2.5 for the protection of the special value of Class II waters. Although required to account for cumulative impacts, the plan will necessarily reflect the characteristics of the site--e.g., 1.6 acres contributing largely automobile-based contaminants and not nutrients--and the characteristics of the receiving waters--e.g., Tampa Bay is vast and relatively impaired, though, in the vicinity of the subject site, more likely due to excessive nutrients.

Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: Background Petitioner, Champagne Estates (petitioner or applicant), is a limited partnership that owns a tract of land identified as Lots 1-5, Block 88, PGI Section 9A in Punta Gorda, Florida. The property fronts on the south side of the Peace River, a Class III water body which lies within the boundaries of the Charlotte Harbor Aquatic Preserve, a water body designated as an Outstanding Florida Water (OFW). Petitioner is in the process of constructing a thirty unit, two phase luxury condominium project on its property. As an added amenity for the unit owners, petitioner proposes to construct a multi-slip dock in a tear shaped basin that juts slightly inward from the Peace River. It is applicant's proposal to build a dock that has created this controversy. By application dated April 4, 1989, petitioner sought the issuance of a dredge and fill permit from respondent, Department of Environmental Regulation (DER). If approved, the permit would authorize the construction of the dock. The application was received by DER's Fort Myers district office on April 14, 1989, and was given a staff review for sufficiency. After additional information was requested by DER and filed by the applicant, an on-site inspection was conducted by DER personnel on June 2, 1990. An inspection report was thereafter prepared on July 14, 1990, and was used in the formulation of the agency's preliminary decision. That decision, which was styled as a notice of permit denial, was issued on July 25, 1989, and cited several grounds for DER's preliminary action. They included (a) a fear that degradation of waters would occur, (b) applicant's alleged failure to show that the project was not contrary to the public interest in six respects, and (c) a concern that the project and its cumulative impacts would be contrary to the public interest. The agency's notice of permit denial prompted the applicant to initiate this proceeding. The application and project area Applicant initially sought authorization to build a two hundred sixty- three foot dock with six finger piers, a terminal platform and thirteen boat slips. The agency's intent to deny permit was based on that proposal. After the proposed agency action was issued, petitioner modified its application to downsize the dock to one hundred feet with only four finger piers and eight mooring slips. The structure will have a "T" configuration. Under the modified proposal, the finger piers will have a length of twenty feet while the mooring slips are twelve feet wide. Applicant advises that the boats which will use the facility will average between twenty and twenty-six feet in length with drafts of two to three feet. This size and draft is comparable to commercial fishing boats which now frequent the deep water basin to catch mullet. If the application is approved, applicant proposes to place rock riprap at the toe of the existing vertical concrete seawall and to plant red mangroves in the intertidal areas. It also proposes to prohibit "live aboards", fueling and maintenance at the facility. Despite the above modifications and restrictions, DER advised petitioner on October 5, 1989, that the application was still unacceptable for the same reasons as originally given. The parties have agreed that the modified application is the subject of this proceeding. The basin in which the construction will occur was excavated in the 1960's. A thirteen foot deep east-west channel runs parallel to the shore several hundred feet from the shoreline. There are existing seawalls on both the southern and western shorelines of the project area which form an "L" at the intersection. The basin is tear shaped with a width of approximately one hundred feet and commences some one hundred feet waterward of the shoreline. The "T" finger pier structures will be at the southerly edge of the existing basin thereby giving vessels access to the east-west channel. During low tide the bottom of the water body is exposed for more than one hundred feet seaward of petitioner's property. Thus, most, if not all, of the dock will be over exposed areas during low tide, and even during high tide the water in the surrounding basin area will be no more than a few feet deep. The proposed project has existing condominiums on both sides. Virtually all of the remaining lots on either side of the project stretching a mile or so in both directions are developed with single or multifamily units. If approved, petitioner's dock would be the only such dock in the immediate area on the south side of the river. Water quality concerns An applicant for a dredge and fill permit is obliged to provide "reasonable assurance" that water quality standards will not be violated. Since the proposed project is within the boundaries of the Charlotte Harbor Aquatic Preserve, which is designated as an OFW, special water quality considerations come into play. More specifically, the project must maintain the ambient water quality standards of the OFW. This means that a permit cannot be issued for a project that will lower the ambient water quality, that is, the water quality existing one year prior to the date the body was designated an OFW, or the water quality existing one year prior to the project, whichever is better. One way in which ambient water quality can be degraded is by the resuspension of bottom solids caused by the churning of boat propellers. The likelihood of this condition occurring is made greater when insufficient water depths exist in combination with the existence of mucky, silty bottoms. The bottoms surrounding the proposed docking structure are nonvegetative and vary from hard sand in the shallow areas to a mucky silt layer in the deeper sections of the area. The accumulated sediment in the deeper section of the basin is on the order of twenty-four inches. While the hard sand bottom will readily settle out, the mucky bottom sediments will likely be churned by the boat activity in the absence of sufficient water depths. There is conflicting evidence regarding the depths of the water in the area of the basin where the proposed dock will be constructed. In support of its application, petitioner provided a chart indicating the topography of the sea bottoms at the proposed dock site. However, the geographic survey chart does not establish that sufficient water depth exists for the proposed dock. Rather, the more credible evidence establishes that the bottoms of the basin where the proposed dock will be built are often exposed and during low tides the sea bottoms are exposed up to approximately one hundred to one hundred fifty feet seaward of the seawall. Moreover, in the winter months, the westerly winds push the water out of the basin and cause the exposure of sea bottoms up to two hundred feet seaward of the seawall. When these shallow depths are coupled with the soupy texture of the bottom sediment, it is found that resuspension of the bottom sediment will occur as a result of boat activity at the proposed docking site. To the extent turbidity is now present in the basin due to the activities of the commercial fishermen, these turbidity levels will be exacerbated. If, as applicant suggests, the proposed facility will eliminate the commercial mullet fishing activities within the basin, there is no reasonable assurance that the new levels of turbidity will not exceed those now present. Therefore, it is found that applicant has not given reasonable assurance that the water quality standards will not be degraded. The agency's next concern involves its so-called "free-from" standard, which literally means that assurance must be given by the applicant that a water body will be "free from" various types of man-induced components (e. g., debris, oil, and scum) that float in such amounts as to form a nuisance. Thus, applicant was required to give reasonable assurance that the project would not cause an accumulation of debris and other items on the surface of the water in such amounts as to constitute a nuisance. The project site is "L" shaped, the "L" caused by the intersection of two seawalls on its western side. During the inspections of the project site by DER personnel, an accumulation of debris (grass clippings, styrofoam cups, coconuts, etc.) was observed in the corner of the "L". Indeed, applicant concedes that "some such debris is regularly present in the vicinity of the proposed docking structure" but contends that the docking facility will not cause significant additional floatsom or scum. However, it is found that due to the shape of the basin and its lack of sufficient water depth, the project will exacerbate the accumulation of debris so as to cause a nuisance. Finally, because of the shallow water in the basin, there exists the likelihood that dissolved oil or visible oil will form in the waters and affect its taste or give rise to an odor or otherwise affect the beneficial use of the waters. D. Public Interest Considerations In order for a permit to issue, and because the project is in an OFW, the applicant is obliged to show that the project "will be clearly in the public interest." The public interest test involves a consideration of seven statutory criteria. In this case, DER contends that six of the seven criteria enumerated in the law (s. 403.918(2)(a)1.-5. and 7., F.S.) have not been satisfied. The first criterion requires an inquiry as to whether the project will adversely affect the public health, safety, or welfare of the property of others. In this regard, it is noted that the proposed activity will take place in an OFW, a pristine water body. According to the agency, the maintenance of that water body "is in the welfare of all the citizens of the State of Florida, not just the residents of Champagne Estates or the adjacent condominium owners." Because the operation of boats will cause a degradation of the waters in the basin area, this will have an adverse effect on the public welfare. While applicant proposes to offer mitigation in the form of riprap and new mangroves, the success rates for mitigation proposals such as this are less than fifty per cent and do not offer sufficient assurance to counter the adverse effect on the public welfare. The second criterion concerns whether the project will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats. Uncontradicted testimony established that stingray, bait fish, sheepshead, minnows, brown pelican, osprey, bottlenosed dolphin, and loggerhead turtles habitat the project area. In addition, the proposed dock has been designated as a critical habitat for the manatee. Due to the resuspension of bottom solids caused by boat traffic in the shallow waters, the wildlife and fish in the area of the proposed dock will be adversely impacted. This is because elevated levels of turbidity are detrimental to aquatic species that breath water, especially for those that filter feed and pass the fluid through their bodies. The next relevant criterion is whether the project will adversely affect navigation or the flow of water or cause harmful erosion or shoaling (i. e., cause an area to shallow in). As to this criterion, applicant's uncontradicted evidence that the project will not affect navigation, the flow of water, or cause harmful erosion or shoaling is accepted, and it is found that this criterion has been satisfied. The fourth criterion in issue is whether the project will adversely affect the fishing or recreational values or marine productivity in the vicinity of the project. While the fishing or recreational values should not be adversely affected, the turbidity caused by the boats propellors will impact the marine productivity in an adverse manner. Therefore, this criterion has not been met. The next criterion concerns whether the project will be of a temporary or permanent nature. The evidence shows that the project will be of a permanent nature, that is, once constructed, the applicant does not plan on tearing down the structure. However, neither party offered evidence as to how this consideration comes into play in the context of the public interest test, and it is accordingly found that applicant has not satisfied this requirement. The last disputed criterion concerns the current condition and relative value of functions being performed by areas affected by the proposed activity. By virtue of the increased turbidity levels, it is found that the relative value and use of the area will be degraded. E. Cumulative Impacts In its proposed agency action, the agency contended that "the project and its cumulative impacts . . . also fail to be clearly in the public interest." This objection is grounded on the statutory requirement that the agency consider the "other projects which may reasonably be expected to be located within the jurisdictional extent of waters, based upon land use restrictions and regulations." (s. 403.419(3), F.S.) According to an agency witness, applicant's project, if approved, would be the only docking facility on the south shoreline of the Peace River for some distance in either direction. Although DER does not have any pending applications for docks, and knows of none that will be filed, it "felt" there was a potential cumulative impact in that other condominium projects in the area would seek a docking permit once it became known that applicant had constructed such a facility. However, this "feeling" is insufficient to establish a finding that there is a potential adverse cumulative impact related to the project.

The Issue The issue is whether Ponce Marina, Inc., (Ponce Marina) is entitled to a dredge and fill permit and water quality certification number 64-1303059 to construct a marina on the Halifax River in Volusia County, Florida.
Findings Of Fact The Department received an application from Ponce Marina on February 6, 1987, for a permit/water quality certification to construct a 178 slip marina facility consisting of two marina basins and two access channels. The work was to be done in primarily existing uplands adjacent to the Intercoastal Waterway (ICW) within the boundaries of the Town of Ponce Inlet, Volusia County, Florida. In response to agency objections, the scope of the project was reduced to include the excavation of a single marina basin and entrance channel and the construction of a 142 slip marina, by: constructing a basin by excavating 153,000 cu. yds. of material landward of mean high water (MHW) to a maximum depth of -6 feet mean low water (MLW); constructing an entrance channel 200 feet long by 80 feet wide by hydraulically dredging 2,100 cu. yds. waterward of MHW to a maximum depth of -7 feet MLW; connecting the head region of the excavated basin to an existing tidal creek by installing a 60 foot long, 36 inch diameter culvert pipe set at invert -2.0 feet NGVD and fitted with a 36 inch flap gate; installing 1,695 linear feet of vertical bulkhead with a riprap toe, 1,200 linear feet of native rock revetment, 680 linear feet of native rock riprap for use as wave-breaks; constructing 3 main piers, 8 feet in width and 140 feet, 180 feet and 210 feet in length, and 66 finger piers 3 feet in width and 30 feet to 50 feet in length, providing 142 wet boatslips; constructing a stormwater treatment system for the upland development associated with the marina facility; filling a 0.53 acre barrow canal with 4,000 cu. yds. of material; impacting 2.44 acres of jurisdictional wetland area; and creating 2.9 acres of jurisdictional wetland area. The application was filed on behalf of Ponce Marina by Robert M. Snyder, P.E., a professional engineer registered in the State of Florida. On June 20, 1988, the Department issued its Intent to Issue Permit No. 64-1303059 to Ponce Marina. The Intent to Issue contains 21 Specific Conditions the Department will place on the Permit. All conditions are reasonable and necessary. The project site is located on the eastern side of the Halifax River, 3.5 miles south of the Port Orange Causeway and 2.3 miles north of Ponce Inlet in the Town of Ponce Inlet, Volusia County, Section 24, Township 16 South, Range 33 East, not in aquatic preserve, in Class III waters. The project site was formerly salt marsh associated with the Halifax River. The majority of the project site now consists of fill placed on the salt marsh at some time in the past. This fill created an upland strip approximately 500 feet wide and 2,000 feet long. Running through this upland strip is a central ditch which originates at a stormwater sewer on the east side of South Peninsula Drive and runs toward the west to the Halifax River. The proposed marina basin is to be excavated from the upland strip and central ditch described above. The marina design includes the creation of a wetland area in the head region of the basin as well as the connection of the head region to Live Oak Creek, an existing tidal creek, by installing a 60 feet long, 36 inch diameter culvert set at -2.0 feet NGVD and fitted with a 36 inch flap gate. The estuarine marsh wetland to be created at the head of the marina is designed to provide water quality treatment to incoming tides which reach this area. This treated water will then move through the flap gate into Live Oak Creek, where it will receive further treatment before entering the Halifax River. The entrance to the marina will be 180 feet wide. The dredged access channel through that 180 feet entrance, for the navigation of deeper draft boats, will be 80 feet wide by 200 feet long. Construction of the entrance channel will require the excavation of approximately 2,100 cu. yds. of material from the submerged lands of the Halifax River, however, the areas to be dredged consist of unvegetated sand which is not expected to impact marine resources. Excavation of the marina basin will result in 2.44 acres of direct wetland loss. These wetlands are mainly associated with the central ditch. Some marsh north of the upland strip will also be encroached upon. The wetland area eliminated by construction will be replaced by the creation of 2.9 acres of wetland area to be planted with mangroves and smooth cordgrass. It is expected that the created wetland area will provide those same functions as the replaced wetlands within four to five months of planting and will become fully established within two to three years of planting. There is an extremely high success rate for this type of created wetlands within marina basins. The proposed mitigation provides a 1.3:1 ratio of created saltmarsh and mangrove areas and is consistent with Department policy. Diverse shoreline treatments are proposed which will protect wetland and vegetated areas within the marina basin from boat wakes and high energy exchange. This shoreline treatment will include vertical bulkheads, sloping native rock revetments, and submerged wake breaks. There are two or more boat slips directly adjacent to the created wetland on the south side of the basin. Boats in these slips can easily hit the wetlands and damage them. These slips should be eliminated or redesigned to provide protection for these wetlands. The created wetlands are placed so as to provide nursery habitat adjacent to deep water and to filter and treat tidal waters as they move through them. The location and proximity to open water of the created wetlands and the flushing characteristics of the basin will result in higher quality wetlands than those being replaced. The approximately 94 acres of remaining wetlands surrounding the marina project will be placed in a perpetual conservation easement by Ponce Marina. This conservation easement will include two spoil islands to the south of the main upland portion of the property as well as a nonjurisdictional Oak Hammock to the north of the project. The marina, as designed, is a system which is hydraulically driven by the tide. The tide in this region has a mean range of 2.77, that is, a 2.77 feet amplitude change from slack low water to slack high water. In this particular marina system, flushing is driven by two tidal components: (1) a tidal prism which is nothing more than the ratio of the tide volume to the mean low water volume of the basin and, (2) a flow-through component which occurs because there is an elevation difference from one portion of the system to another. A more rigorous flushing action occurs in a flow- through system. The marina is designed with a flap gate so that the facility will have a flow-through potential. Because a flow- through system generates turbulence, it provides mixing through the water column to eliminate or greatly minimize potential for pockets of water that could become stagnant. This is particularly effective in the head regions of the basin. The flap gate operates not only to ensure that water regularly moves out of the head region, but also to ensure that water from the marsh area will not flow into the marina basin, since such water contains organics which could be transported into the marina basin, thereby increasing the potential to violate dissolved oxygen standards. The marina, as designed, will provide a flushing time of 4.6 days for 100 percent flushing, which is adequate to provide reasonable assurance that water quality standards will not be degraded in either the marina basin or adjacent waters. The velocity of water going through the flap gate will not cause erosion. While no operational problems are anticipated with the flap gate, its proper operation is critical to the flushing of the basin. An appropriate design and regular maintenance will be necessary for the flap gate to operate as anticipated. There is no condition in the Intent to Issue which addresses the design and maintenance of the flap gate. Such a condition should be included. The east-west portion of an existing L-shaped canal situated in the northern portion of the property will be filled. The area to be filled is .53 acres. The L-shaped canal is within the Department's jurisdiction, is connected to the Halifax River, and is therefore waters of the State. There is a 36-inch culvert coming from under Peninsula Drive which takes stormwater runoff from an existing condominium development and empties that runoff into the L-shaped canal. Currently, untreated water is coming off impervious surfaces and under the highway by pipe directly into waters of the state, with no detention, no retention, no initial treatment. Therefore, the worst pollutant slug is going directly into waters of the state. This stormwater runoff receives no treatment prior to being directly discharged to waters of the state. Such a system would not be permitted by the Department today. State water quality will be improved by removing the direct stormwater drainage to waters of the state. Ponce Marina has provided an alternate plan for the water which is currently coming from off the project site and discharging through the 36-inch culvert directly into waters of the state. The water is to be routed through a considerable length of grassy ditch behind a weir which will retain the water so that it will receive proper treatment before entering the marsh area. This stormwater will not be routed to a retention area in the oak hammock to the north of the project. The water quality in the remaining portion of the L- shaped canal will not be reduced by the filling of the .53 acre east-west segment, nor is it expected to decline after the filling. The proposed stormwater treatment system for the marina project meets the criteria specified by Florida Administrative Code Chapter 17-25. Further, the stormwater management system for the project was never properly made an issue in this proceeding. The U. S. Fish and Wildlife Service issued a no jeopardy letter to Ponce Marina on July 11, 1988, indicating that the proposed marina will not endanger the manatee or the Atlantic Saltmarsh snake. Those are the only endangered or threatened species that would be expected to be affected by this project. On September 1, 1987, Colonel Robert M. Brantly, Executive Director of the Florida Game and Fresh Water Fish Commission, issued a letter to Secretary Dale Twachtmann recommending, (1) the southern basin of the original marina project be eliminated; (2) the remaining northern basin be designed to lessen wetland impacts, a hydrographic analysis be performed to ensure adequate flushing, there be a DNR determination of no adverse impact to the manatee; and (3) the oak hammock be preserved before issuance of the permit. These recommendations were followed by the Department and are incorporated in the current proposal for the project. On August 21, 1987, the Florida Department of Natural Resources issued its recommendations to the Department concerning the proposed marina, as it relates to the manatee. The recommendations of the DNR are incorporated in permit conditions 16, 17, and 18a through 181. A March 16, 1987, report prepared by staff of the Environmental Control Division of Volusia County recommended approval of the original marina project with three recommendations. Although Volusia County recommended a 90 percent survival rate, an 80 percent survival rate in the mitigation plan is reasonable. Marina plans provide for a sewage pump-out service for boats, as recommended. A condition prohibiting live-aboards on vessels was inadvertently omitted from the condition in the Intent to Issue. The PAC called as its only witness, Dr. Bernard J. Yokel, who was qualified as an expert in estuarine ecology and fisheries. Although Dr. Yokel expressed concern about the removal of a portion of the L-shaped canal and on the introduction of water from the marina into Live Oak Creek, there was no testimony whatsoever that it would be a violation of any criteria of the Department's Class III Water Standards or any other promulgated departmental standard. In fact, Dr. Yokel was unfamiliar with the provisions of Chapters 17- 3 and 17-4, Florida Administrative Code, and was also unfamiliar with the Coastal Marinas Assessment Handbook, the 1985 version published by the Environmental Protection Agency (EPA). Although Dr. Yokel expressed some concern regarding the impact of the marina on the existing linear wetlands in the ditches, he never rendered any opinion as to whether or not reasonable assurances had been provided that the proposed permit was contrary to the public interest, would cause adverse water quality or have adverse effects on fish, shellfish, crabs, and other wildlife. He rendered no opinion as to whether or not the proposed project, if permitted, would adversely affect the conservation of fish and wildlife. The Petitioner, Lawrence Decker, did not testify. He did present Robert Bullard, P.E., as an expert. Mr. Bullard expressed concern about the operation of the flap gate between the marina basin and Live Oak Creek. However, Mr. Bullard expressed no opinion as to whether or not there would be a violation of any criteria contained in Chapters 17-3, 17-4, or 17-25, Florida Administrative Code, or of the Department's Class III Water Quality Standards. The witness, Mr. Bullard, also expressed concern about the hydrographic characteristics of the marina basin and of the L-shaped canal. However, Mr. Bullard never expressed an opinion that the project as designed would degrade State Water Quality Standards below those set in Chapters 17-3, 17-4, and 17-25, Florida Administrative Code, or the Department's Class III Water Quality Standards. Mr. Bullard never expressed any opinion as to whether or not reasonable assurances had been given by the applicant, Ponce Marina, to the Department, that the project would not meet the criteria as provided in Chapter 403, Florida Statutes, or the rules promulgated by the Department thereunder. The applicant, Ponce Marina, has provided reasonable assurances that the project will not violate water quality standards or other standards established pursuant to Chapter 493, Florida Statutes, and Rules 17-3.051, 17- 3.061, and 17-3.121, Florida Administrative Code, relating to Class III waters. The project as designed is not contrary to the public interest. The mitigation more than offsets the wetlands lost. There is evidence to establish that the project, with mitigation, will not adversely affect the public health, safety, welfare, or property of others; nor adversely affect the conservation of fish and wildlife, including endangered or threatened species or their habitats; nor adversely affect navigation or flow of water or cause harmful erosion or shoaling; nor adversely affect the fishing or recreational value or marine productivity in its vicinity; nor adversely affect significant historical or archaeological resource.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Regulation enter a Final Order and therein grant permit number 64-1303059 to Ponce Marina, Inc., with three additional specific conditions added to the twenty-one conditions set forth in the Intent to Issue: No live-aboard vessels are to be allowed at the marina. The applicant shall design and shall provide regular maintenance for the flap gate so as to insure that the flap gate will perform as required as an integral and critical component of the flushing design of the marina basin. The applicant shall eliminate or redesign the boat slips directly abutting the created wetlands on the south side of the basin, so as to protect those wetlands from damage.

The Issue The issues to be resolved in this proceedings concern whether Environmental Resource Permit (ERP) No. 4-109-0216-ERP, should be modified to allow construction and operation of a surface water management system (project) related to the construction and operation of single-family homes on "Marshall Creek" (Parcel D) in a manner consistent with the standards for issuance of an ERP in accordance with Rules 40C-4.301 and 40C-4.302, Florida Administrative Code.
Findings Of Fact The Project The project is a 29.9-acre residential development and associated stormwater system in a wetland mitigation area known as "Parcel D." It lies within the much larger Marshall Creek DRI in St. Johns County, Florida, bounded on the northeast by Marshall Creek, on the south and southeast by a previously permitted golf course holes sixteen and seventeen, and on the north by the "Loop Road." The project consists of thirty residential lots of approximately one-half acre in size; a short segment of Loop Road to access Parcel D; an internal road system; expansion of previously permitted Pond N, a wet detention stormwater management pond lying north of the Loop Road and wetland mitigation areas. Approximately 1.15 acres of wetlands are located on the Parcel D site. The project plan calls for filling 0.63 acres of the wetlands for purposes of constructing a road and residential lots for Parcel D. Part of that 0.63-acre impact area, 0.11 acres, is comprised of a 760-foot-long, narrow drainageway, with 0.52 acres of adjacent wetland. Downstream of the fill area, 0.52 acres of higher quality wetland is to be preserved. Hines proposes to preserve 4.5 acres of existing wetland and 2.49 acres of upland, as well as to create .82 acres of forested wetland as mitigation for the proposed impact of the project. Additionally, as part of the project, Hines will implement a nutrient and pesticide management plan. The only pesticides to be used at the project will be approved by the Department of Agriculture for use with soil types prevailing at the site and only pesticides approved by the Environmental Protection Agency may be used on the site. All pesticides to be used on the project site must be selected to minimize impacts to ground and surface water, including having a maximum 70-day half-life. Stormwater Management System The majority of surface runoff from Parcel D will be diverted to a stormwater collection system and thence through drainage pipes and a swale into Phase I of Pond N. After treatment in Pond N, the water will discharge to an upland area adjacent to wetlands associated with Marshall Creek and then flow into Marshall Creek. The system will discharge to Marshall Creek. In addition to the area served by Pond N, a portion of lots fourteen though twenty drain through a vegetated, natural buffer zone and ultimately through the soil into Marshall Creek. Water quality treatment for that stormwater runoff will be achieved by percolating water into the ground and allowing natural soil treatment. The fifty-foot, vegetated, natural buffer is adequate to treat the stormwater runoff to water quality standards for Lots 14, 15 and 20. Lots 16, 17, 18 and 19, will have only a twenty-five foot buffer, so additional measures must be adopted for those lots to require either that the owners of them direct all runoff from the roofs and driveways of houses to be constructed on those lots to the collection system for Pond N or placement of an additional twenty-five foot barrier of xeriscape plants, with all non- vegetated areas being mulched, with no pesticide or fertilizer use. An additional mandatory permit condition, specifying that either of these measures must be employed for Lots 16, 17, 18 and 19, is necessary to ensure that water quality standards will be met. Pond N is a wet detention-type stormwater pond. Wet detention systems function similarly to natural lakes and are permanently wet, with a depth of six to twelve feet. When stormwater enters a wet detention pond it mixes with existing water and physical, chemical and biological processes work to remove the pollutants from the stormwater. Pond N is designed for a twenty-five year, twenty-four- hour storm event (design storm). The pre-development peak rate of discharge from the Pond N drainage area for the design storm event is forty cubic feet per second. The post-development peak rate of discharge for the design storm event will be approximately twenty-eight cubic feet per second. The discharge rate for the less severe, "mean annual storm" would be approximately eleven cubic feet per second, pre-development peak rate and the post-development peak rate of discharge would be approximately five cubic feet per second. Consequently, the post-development peak rate of discharge does not exceed the pre- development peak rate of discharge. Pond N is designed to meet the engineering requirements of Rule 40C-42.026(4), Florida Administrative Code. Because the pond is not designed with a littoral zone, the permanent pool volume has been increased by fifty-percent. Additionally, because Pond N discharges to the Class II waters of Marshall Creek, an additional fifty-percent of treatment volume is included in the pond design. The system design addresses surface water velocity and erosion issues through incorporation of best management practices promulgated by the District to prevent erosion and sedimentation, including; designing side slopes of 4:1; siding and seeding disturbed areas to stabilize soil; and the use of riprap at the outfall from Pond N. During construction, short- term water quality impacts will be addressed through installation of silt fences and hay bales. The majority of the eighteen-acre drainage basin which flows into the Parcel D wetland lies to the south and southwest of Parcel D. In accordance with the prior permit, water from those off-site acres will be intercepted and routed to stormwater ponds serving golf course holes sixteen and seventeen. The system design will prevent adverse impacts to the hydroperiod of remaining on-site and off-site wetlands. The remaining wetlands will be hydrated through groundwater flow. Surface waters will continue to flow to the wetlands adjacent to lots fourteen through twenty because drainage from those lots will be directed across a vegetated, natural buffer to those wetlands. There is no diversion of water from the natural drainage basin, because Pond N discharges to a wetland adjacent to Marshall Creek, slightly upstream from the current discharge point for the wetland which is to be impacted. This ensures that Marshall Creek will continue to receive that fresh-water source. An underground "PVC cut-off wall" will be installed around Pond N to ensure that the pond will not draw down the water table below the wetlands near the pond. Pond N has been designed to treat stormwater prior to discharge, in part to remove turbidity and sedimentation. This means that discharge from the pond will not carry sediment and that the system will not result in shoaling. There will be no septic tanks in the project. The system is a gravity flow system with no mechanical or moving parts. It will be constructed in accordance with standard industry materials readily available and there will be nothing extraordinary about its design or operation. The system is capable of being effectively operated and maintained and the owner of the system will be the Marshall Creek Community Development District (CDD). Water Quality Water entering Pond N will have a residence time of approximately 200 days or about fifteen times higher than the design criteria listed in the below-cited rule. During that time, the treatment and removal process described herein will occur, removing most of the pollutants. Discharge from the pond will enter Marshall Creek, a Class II water body. The discharges must therefore meet Class II water quality numerical and anti-degradation standards. The design for the pond complies with the design criteria for wet detention systems listed in Rule 40C-42.026(4), Florida Administrative Code. In addition to meeting applicable design criteria, the potential discharge will meet water quality standards. The pond will have low levels of nitrogen and phosphorous resulting in low algae production in the pond. The long residence time of the water in the pond will provide an adequate amount of time for pesticides to volatilize or degrade, minimizing the potential for pesticide discharge. Due to the clear characteristics of the water column, neither thermal stratification nor chemical stratification are expected. Periodically, fecal coliform and total coliform levels are exceeded under current, pre-development conditions. These are common natural background conditions. Because the detention time in the pond will be an average of 200 days, and because the life span of fecal coliform bacteria is approximately seven to fourteen days the levels for coliforms in the pond will be very low. Discharges from the pond will enhance water quality of the Class II receiving waters because the levels of fecal coliform and total coliform will be reduced. The discharge will be characterized by approximately 100 micrograms per liter total nitrogen, compared with a background of 250 micrograms per liter presently existing in the receiving waters of Marshall Creek. The discharge will contain approximately three micrograms per liter of phosphorous, compared with sixty-three micrograms per liter presently existing in Marshall Creek. Total suspended solids in the discharge will be less than one-milligram per liter compared with seventy-two milligrams per liter in the present waters of Marshall Creek. Biochemical oxygen demand will be approximately a 0.3 level in the discharge, compared with a level of 2.4 in Marshall Creek. Consequently, the water quality discharging from the pond will be of better quality than the water in Marshall Creek or the water discharging from the wetland today. The pollutant loading in the discharge from the stormwater management system will have water quality values several times lower than pre-development discharges from the same site. Comparison of pre-development and post-development mass loadings of pollutants demonstrates that post-development discharges will be substantially lower than pre-development discharges. Currently, Marshall Creek periodically does not meet Class II water quality standards for dissolved oxygen. Construction and operation of the project will improve water quality in the creek concerning dissolved oxygen values because discharges from Pond N will be subjected to additional aeration. This results from design features such as discharge from the surface of the system, where the highest level of dissolved oxygen exists, and the discharge water draining through an orifice and then free falling to a stormwater structure, providing additional aeration. Discharges from the system will maintain existing uses of the Class II waters of Marshall Creek because there will be no degradation of water quality. Discharges will not cause new violations or contribute to existing violations because the discharge from the system will contain less pollutant loading for coliform and will be at a higher quality or value for dissolved oxygen. Discharges from the system as to water quality will not adversely affect marine fisheries or marine productivity because the water will be clear so there will be no potential for thermal stratification; the post-development discharges will remain freshwater so there will be no change to the salinity regime; and the gradual pre-development discharges will be replicated in post-development discharges. Several factors minimize potential for discharge of pesticide related pollutants: (1) only EPA-approved pesticides can be used; (2) only pesticides approved for site-specific soils can be used; (3) pesticides must be selected so as to minimize impacts on surface and groundwater; (4) pesticides must have a maximum half-life of 70 days; and (5) the system design will maximize such pollutant removal. Archaeological Resources The applicant conducted an archaeological resource assessment of the project and area. This was intended to locate and define the boundaries of any historical or archaeological sites and to assess any site, if such exists, as to its potential eligibility for listing in the National Register of Historic Places (National Register). Only a portion of one archaeological site was located on the project tract. Site 8SJ3473, according to witness Anne Stokes, an expert in the field of archaeological assessment, contains trace artifacts dating to the so-called "Orange Period," a time horizon for human archaeological pre-history in Florida dating to approximately 2,300 B.C. The site may have been only a small campsite, however, since only five pottery fragments and two chert flakes, residuals from tool-making were found. Moreover, there is little possibility that the site would add to knowledge concerning the Orange Period or pre-history because it is a very common type of site for northeast Florida and is not an extensive village site. There are likely other campsites around and very few artifacts were found. No artifacts were found which would associate the site with historic events or persons. The applicant provided the findings of its cultural resource assessment, made by Dr. Stokes, to the Florida Division of Historical Resources. That agency is charged with the responsibility of reviewing cultural resource assessments to determine if significant historic or archaeological resources will be impacted. The division reviewed the survey techniques used by Dr. Stokes, including shovel testing, sub-surface testing and pedestrian walk-over and investigation. The division determined that the site in question is not of a significant historical or archaeological nature as a resource because it does not meet any of the four criteria for inclusion in the National Register.1 Thus the referenced agency determined that the site in question is not a significant historical or archaeological resource and that construction may proceed in that area without further investigation, insofar as its regulatory jurisdiction is concerned. Wetlands The wetlands to be impacted by the project consist of a 1,000 foot drainage-way made up of a 0.11 acre open-water channel, approximately four feet wide, and an adjacent vegetated wetland area of approximately 0.52 acres containing fewer than 30 trees. The open-water channel is intermittent in that it flows during periods of heavy rainfall and recedes to a series of small, standing pools of water during drier periods. The Parcel D wetland is hydrologically connected to Marshall Creek, although its ephemeral nature means that the connection does not always flow. The wetland at times consists only of isolated pools that do not connect it to Marshall Creek. Although it provides detrital material export, that function is negligible because the productivity of the adjacent marsh is so much greater than that of the wetland with its very small drainage area. Because of the intermittent flow in the wetland, base flow maintenance and nursery habitat functions are not attributed to the wetland. The Parcel D wetland is not unique. The predominant tree species and the small amount of vegetated wetland are water oak and swamp bay. Faunal utilization of the wetland is negligible. The wetland drainage-way functions like a ditch because it lacks the typical characteristics of a creek, such as a swampy, hardwood floodplain headwater system that channelizes and contains adjacent hardwood floodplains. The location of the wetland is an area designated by the St. Johns County comprehensive plan as a development parcel. The Florida Natural Areas Inventories maps indicate that the wetland is not within any unique wildlife or vegetative habitats. The wetland is to be impacted as a freshwater system and is not located in a lagoon or estuary. It contains no vegetation that is consistent with a saltwater wetland. The retaining wall at the end of the impact area is located 1.7 feet above the mean high water line. Wetland Impacts The proposed 0.63 acre wetland impact area will run approximately 760 linear feet from the existing trail road to the proposed retaining wall. If the wetland were preserved, development would surround the wetland, adversely affecting its long-term functions. Mitigation of the wetland functions is proposed, which will provide greater long-term ecological value than the wetland to be adversely affected. The wetland to be impacted does not provide a unique or special wetland function or good habitat source for fish or wildlife. The wetland does not provide the thick cover that would make it valuable as Black Bear habitat and is so narrow and ephemeral that it would not provide good habitat for aquatic-dependent and wetland-dependent species. Its does not, for instance, provide good habitat for woodstorks due to the lack of a fish population and its closed- in tree canopy. Minnow sized fish (Gambusia) and crabs were seen in portions of the wetland, but those areas are downstream of the proposed area of impact. Mitigation Mitigation is offered as compensation for any wetland impacts as part of an overall mitigation plan for the Marshall Creek DRI. The overall mitigation plan is described in the development order, the mitigation offered for the subject permit and mitigation required by prior permits. A total of 27 acres of the more than 287 acres of wetlands in the total 1,300-acre DRI tract are anticipated to be impacted by the DRI. Approximately 14.5 acres of impacted area out of that 27 acres has already been previously authorized by prior permits. The overall mitigation plan for the DRI as a whole will preserve all of the remaining wetlands in the DRI after development occurs. Approximately one-half of that preserved area already has been committed to preservation as a condition of prior permits not at issue in this case. Also, as part of prior permitting, wetland creation areas have been required, as well as preserved upland buffers which further protect the preserved wetlands. The mitigation area for the project lies within the Tolomato River Basin. The development order governing the total DRI requires that 66 acres of uplands must also be preserved adjacent to preserved wetlands. The overall mitigation plan for the DRI preserves or enhances approximately 260 acres of wetlands; preserves a minimum of 66 acres of uplands and creates enhancement or restores additional wetlands to offset wetland impacts. The preserved wetlands and uplands constitute the majority of Marshall Creek, and Stokes Creek which are tributaries of the Tolomato River Basin, a designated Outstanding Florida Water (OFW). Preservation of these areas prevents them from being timbered and ensures that they will not be developed in the future. The overall DRI mitigation plan provides regional ecological value because it encompasses wetlands and uplands they are adjacent to and in close proximity to the following regionally significant resources: (1) the 55,000 acre Guana- Tolomato-Matanzas National Estuarine Research Reserve; (2) the Guana River State Park; (3) the Guana Wildlife Management Area; (4) an aquatic preserve; (5) an OFW; and (6) the 22,000 acre Cummer Tract Preserve. The mitigation plan will provide for a wildlife corridor between these resources, preserve their habitat and insure protection of the water quality for these regionally significant resources. The mitigation offered to offset wetland impacts associated with Parcel D includes: (1) wetland preservation of 0.52 acres of bottom land forest along the northeast property boundary (wetland EP); (2) wetland preservation of 3.98 acres of bottom land forest on a tributary of Marshall Creek contained in the DRI boundaries (Wetlands EEE and HHH); (3) upland preservation of 2.49 acres, including a 25-foot buffer along the preserved Wetlands EEE and HHH and a 50-foot buffer adjacent to Marshall Creek and preserved Wetland EP; (4) a wetland creation area of 0.82 acres, contiguous with the wetland preservation area; and (5) an upland buffer located adjacent to the wetland creation area. The wetland creation area will be graded to match the grades of the adjacent bottomland swamp and planted with wetland tree species. Small ponds of varying depths will be constructed in the wetland creation area to provide varying hydrologic conditions similar to those of the wetland to be impacted. The wetland creation area is designed so as to not de-water the adjacent wetlands. All of the mitigation lands will be encumbered with a conservation easement consistent with the requirements of Section 704.06, Florida Statutes. The proposed mitigation will offset the wetland functions and values lost through the wetland impact on Parcel D. The wetland creation is designed to mimic the functions of the impact area, but is located within a larger ecological system that includes hardwood wetland headwaters. The long-term ecological value of the mitigation area will be greater than the long-term value of the wetland to be impacted because; (1) the mitigation area is part of a larger ecological system; (2) the mitigation area is part of an intact wetland system; (3) the wetland to be impacted will be unlikely to maintain its functions in the long-term; and (4) the mitigation area provides additional habitat for animal species not present in the wetland to be impacted. Certain features will prevent adverse secondary impacts in the vicinity of the roadway such as: (1) a retaining wall which would prevent migration of wetland animals onto the road; (2) a guard rail to prevent people from moving from the uplands into wetlands; and (3) a vegetated hedge to prevent intrusion of light and noise caused by automotive use of the roadway.
Recommendation Having considered the foregoing Findings of Fact and Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is RECOMMENDED: That a final order be entered granting the subject application for modification of Permit 4-109-0216A-ERP so as to allow construction and operation of the Parcel D project at issue, with the addition of the inclusion of a supplemental permit condition regarding the vegetated natural buffers for Lots 16 through 19 described and determined above.

Findings Of Fact The Applicant, John E. Bravo, applied for a dredge and fill permit to construct a dockage facility. The proposed facility will consist of a 910 foot pier with a "T"-shaped platform structure extending perpendicular in two directions from the seaward end of the pier, all of which is designed to accommodate 56 boat slips, restricted to the use of pleasure boats only. The proposed project site is located on the southeast side of "Long Point" and would extend into the waters of East Bay, which is a tidally influenced water body in Bay County, Florida. The project site lies in Class II waters of the State. The waters involved are not approved for shellfish harvesting, however, but rather are under a shellfish harvesting prohibition imposed by the Department of Natural Resources. The portion of East Bay involved also lies within the Intracoastal Waterway. The waterway is approximately 6,000 feet wide at the site of the proposed docking facility. The water along the shoreline of the area is shallow for a considerable distance waterward. The bay bottom is characterized by profuse seagrass for approximately 500 feet waterward of mean high water. Beyond that point, the seagrass (Cuban Shoal Grass) dissipates and disappears. The first 400 feet waterward of the mean high water line at the location of the proposed dock, is shallow and not truly navigable. The water then deepens to approximately five feet at mean low water some 525 feet from the shore. This distance from the shore marks the beginning of the area where no significant amount of seagrass exists and where the boat docking slips and mooring pilings would be installed in a waterward direction down the remaining length of the proposed dock. The water depth continues to increase to approximately 20 feet at the proposed location of the end of the dock. The dock would be constructed of pilings driven into the bay bottom supporting the decking of the walkway portion and "T" portion of the dock. The "T" would be installed on the seaward end of the dock, perpendicular to the walkway portion of the dock with most of the boat slips installed and operated at that point. The length of the docking facility is dictated by the fact that the Applicant seeks to locate the boat slips in a manner so that all boats will be moored and operated well beyond existing seagrasses. In fact, the length of the dock is more than absolutely necessary to accomplish this purpose since water depth and avoidance of seagrasses could accomplished with the dock ending approximately 700 feet from the mean high water line. In an abundance of caution, however, in order to avoid the possibility of propeller dredging and prop wash damaging the bottom substrates and grasses, and since the Intracoastal Waterway is over a mile wide here, the Applicant elected to design the dock in the length and configuration proposed. Such will cause no unreasonable impediment to navigation. In this connection, the Applicant has agreed to post Coast Guard- approved safety lights on the dock which will warn boats of its presence in hours of darkness. Further, the dock does not extend far enough into the 6,000 foot wide Intracoastal Waterway to pose a hazard to barge and other boating traffic in the Waterway. Some of the Petitioner's witnesses revealed that shrimp boats pull their nets during shrimping operations closer than 900 feet to the shore line and in the vicinity of the grass beds. While the presence of the dock may alter the trawling pattern of shrimp boats and the operations of other commercial fishermen, as well as water skiing and boating by members of the public, this may in fact have a beneficial effect by promoting the public interest in preserving marine habitat and the conservation of marine resources by preventing some damage to the grass beds. Such marine grass beds are valuable nursery areas for fishes and other marine animals, the effects upon which must be considered in weighing the various statutory indicia of the public interest which must be satisfied before granting a dredge and fill permit. Further, because the dockage facility at issue would be an isolated one with no significant similar docks in the immediate vicinity, the likelihood that it would pose a navigational hazard to water skiiers, fishermen, shrimpers, and other commercial and recreational interests is rather insignificant. Water Quality The water quality issues posed by a project such as this typically involve the water quality parameters of dissolved oxygen, nutrients, bacteriological quality, turbidity, oils, greases, fuel, paint or varnish, solvents and heavy metals, as contemplated by the below-cited rules concerning general surface water quality criteria and the specific rules related to Class II surface waters. The project site is located in Class II surface waters of the State. Those Class II waters are classified by the Department of Natural Resources as "not approved" for shellfish harvesting. The zone of the Class II waters of East Bay in which shellfish harvesting is not approved extends some two miles eastward of the project site. Marinas and dockage facilities such as this one, which will accommodate fairly large boats in significant numbers, typically pose potential pollution problems involving deposition of nutrients in State waters in the form of fish carcasses and offal, garbage and human wastes. Additionally, boats can pose pollution hazards because of attendant dumping of grease, oil and fuel residues in marina waters as well as the deposition of trash in various forms such as paper and plastic items as a result of human use of the boats and the marina facility itself. Perhaps the most severe potential problem is the deposition of human fecal matter into the water as a result of the flushing of marine heads on the larger boats, which the dockage facility will accommodate in the slips as designed. The fecal coliform bacteria which emanate from the deposition of human wastes into the waters around such a dockage facility can be concentrated in oysters and other shellfish to such an extent as to cause severe illness, permanent disability or even death in humans. Consequently, in order to avoid this problem in a magnitude which would violate the water quality parameter in the rule cited below for bacteriological quality, substantial measures must be taken with a project such as this to avoid the deposition of human wastes from the dockage facility itself and from the boats using the slips. In furtherance of this end, the Applicant proposes to allow no live- aboard vessels to be occupied over night while moored at the docking facilities. Live-aboard vessels are deemed to be those with sleeping accommodations and marine heads. The Applicant also proposes to employ a full-time dock master seven days a week, eight hours a day to ensure that all dockage users are familiar with dockage rules, and who would enforce them, especially that prohibiting any discharges from vessels using or docking at the marina. The rules would be incorporated in the dockage lease agreements. The dock master would be responsible for the clean up and correction of all unauthorized discharges. In view of the potential for sewage discharges from marine heads, even with sewage pump-out facilities and the other restrictions on the use of live-aboard type boats, the additional protective measure of requiring a sewage pump-out line and pump-out equipment, including a storage tank and a means to direct sewage pumped from boats into the upland sanitary sewer system, should be imposed as an additional condition. Additionally, the restriction against over night stays aboard boats, the discharge of marine heads into the marina waters and the requirement for use of the sewage pump-out system should be publicized on large, easily legible signs at various points on the pier so that all boat slip renters or users can be on notice of the restrictions and the dock master's and the Department's enforcement of them. Additional potential sources of nutrient and bacteriological degradation of the dissolved oxygen content and bacteriological integrity of the surface waters involved can be posed by the deposition of fish carcasses and parts, as well as food wastes and other garbage in the marina waters. In order to prevent this, the Applicant has proposed to provide fish cleaning stations located on the upland and to require all fish carcasses and other related wastes to be placed in upland containers and not disposed of in the Class II waters at the dock site. Additionally, waste containers will be located along the length and perimeter of the dock facility for garbage, with regular emptying of the containers enforced by the dock master to prevent spillage. In connection with the upland fish cleaning sites to be installed, the drainage waters or waste water from fish cleaning stations should be directed into an upland disposal system so that it may be ensured that the water does not get back into the Class II waters of the bay. In addition to the above measures, pump-out facilities and equipment will be provided by the Applicant for used engine oil removed from boats and oil and water from boat bilges. These wastes, under agreed-upon conditions, would be transported by pipeline to the upland to a storage tank pending proper disposal. Trash, garbage and other refuse will be deposited in dumpsters for removal by municipal garbage disposal services. No fueling facilities or fueling of boats will be allowed. Additionally, oil spill clean up materials will be maintained on the marina site in sufficient quantities to allow clean up of the maximum spill expected from the largest boat typically using the marina pursuant to the leases for the boat slips. In order to further lessen the possibility of spills of oils, greases and fuels, the permit should be conditioned (as should the leases) upon no boat maintenance being performed at the marina site other than minor engine adjustments. In this context, an additional enforcement measure will be in the boat slip rental agreements themselves. The agreements will contain restrictive provisions requiring lessees to properly handle and dispose of fish carcasses and wastes, used engine oil, bilge water and requiring them to comply with sewage pump-out and refuse disposal conditions enumerated above. Upon completion of the facility, the dock master will manage and accomplish maintenance of the various items of equipment, such as the pump-out facility, on an eight hour a day, seven day per week basis and will enforce the restrictive provisions incorporating the above conditions in the boat slip rental agreements. Those restrictive provisions should include putting the lessees on notice that violation of any of the conditions enumerated above and in the boat slip leases will result in a breach of the lease and removal of their vessel from the marina and reporting of the violation to regulatory authorities. The various expert witnesses agreed that the proposed permit conditions enumerated above, if enforced, would adequately protect water quality as to the above parameters at issue. The Class II water quality standards will not be violated by the installation and operation of the project as proposed, provided the above conditions are strictly enforced and adhered to. Mr. Jack Taylor, the expert witness for the Petitioner, agreed that the above measures would reasonably ensure that the marina will not cause pollution and contravention of Class II water quality standards, but feared that enforcement problems would prevent such conditions from prevailing. In view of the measures enumerated above which will be undertaken by the Applicant to ensure that water quality standards are adhered to, including the liberal use of warning signs for marina customers and slip lessees, the use of a full-time dock master to enforce the conditions and including the enforcement measure of putting the conditions as restrictions in the slip rental leases, it has been shown that the enforcement will be reasonably adequate. An additional and important enforcement measure can be incorporated into this project, however, by requiring the Applicant to submit an operation and maintenance plan for the marina and requiring a monitoring program under the auspices of the Department for at least a year of operation in order to ensure that the project operates as it is proposed under the above-delineated conditions. The Department has continuing enforcement power and the monitoring program would, with regular monthly inspections, allow early detection and correction of any water quality violations, to and including the voiding of the permit and the closing of the marina operation should violations prove severe and uncorrectable. 1/ Such a monitoring program and marina operation and maintenance plan should be required as a condition to granting of the permit. 2/ Finally, it should be pointed out that the area of East Bay where the project would be built is Class II shellfish prohibited waters. The proposed project itself will not likely adversely affect shell fishing to the extent of closing additional waters if the above water quality safeguards are imposed as conditions on the permit and on the marina operation. This is especially true because the boundary line of the shellfish approved water to the east is at least two miles away, which distance incorporates a substantial mixing zone in the open waters of East Bay to sufficiently dilute pollutants which might emanate from the marina or other sources to levels such that the shellfish waters presently open will not be subject to any further closures by the Department of Natural Resources, as a result of this installation. The primary reason the shellfish waters in the immediate vicinity of the proposed project are closed to harvesting is the presence of the Military Point Sewage Treatment Plant which discharges its effluent into the waters of East Bay, such that the DNR's dye flow studies reveal that a 5.1 square mile buffer zone around that plant is necessary for closure to shellfish harvesting to ensure that the public health is not adversely affected by consumption of shellfish from the waters in that buffer area. That buffer area includes the proposed marina site. Additional significant pollution sources include fecal coliform bacteria, oils and greases and other contaminants associated with rainfall events and resultant urban runoff from the City of Parker and surrounding areas, including septic tank leachate and petroleum residues. These influences also currently add to the reasons why shellfish harvesting is precluded in the area of the proposed facility. It was not demonstrated that the addition of the marina and the boats operating under the above strict conditions will result in any additional closures to shellfish harvesting in surrounding, presently approved areas as a result of any water quality degradation posed by the subject project. Public Interest The public interest criteria-enumerated at Section 403.918(2)(a), Florida Statutes, which are actually at issue in this proceeding concern: (1) whether the project will adversely affect the public health, safety, welfare or property of others, (2) whether it will adversely affect conservation of fish and wildlife, including their habitats, (3) whether the project will adversely affect navigation, water flow or cause harmful erosion or shoaling, (4) whether it will adversely affect fishing or recreational values or marine productivity in its vicinity, and (5) whether the current condition and relative value of the functions of the natural area involved at the project site will be adversely affected by the proposed activity. There is no issue or dispute raised concerning the permanence of the project for purposes of criteria number 5 under this subsection, nor as to number 6, concerning historical and archaeological resources. Concerning criteria numbered 1-4 and 7, of this subsection, it has been demonstrated that the project will not likely affect the public health, safety, welfare or the property of others if constructed and operated according to the conditions delineated herein. Some members of the public testifying on behalf of the Petitioner objected to the interference they feared the dock would cause with their jogging along the shoreline and feared an impediment to their use of the area for water skiing. This is the only dock in this vicinity, however, and such interference is minor. It will be well lit in order to avoid impeding navigation or posing a danger to the public health or safety during hours of darkness in terms of the public's ability to safely operate boats in the area. There is some potential for the project adversely affecting conservation of fish and wildlife or their habitats in that, if boats are permitted to operate in the vicinity of the dock and use the dock for mooring, loading and unloading purposes, and the like, closer than 500 feet off shore, harmful propeller washing or dredging of the bottom sediments and seagrasses growing therein will result. If such erosion of the bottom and seagrass growth begins occurring, it will adversely affect and gradually destroy the area as a habitat for fish and other marine life, which is of particular importance since such Cuban Shoal Grass stands are quite beneficial as nursery areas for fish and other organisms. Thus, if boating activity were allowed unimpeded around the dock, including in the near shore area within 500 feet from the mean high water line, the resultant erosion and propeller damage to the seagrass beds in the bottom would indicate that, as to criteria 2 and 3 of the above subsection, that the project would not be in the public interest and would be contrary to the public interest. This same consideration is true with regard to the fourth criteria concerning whether the project adversely affects fishing and recreational values or marine productivity for similar reasons. If marine habitat is disrupted or destroyed in whole or in part in the vicinity of the dock due to erosion and other damage caused by boat and propeller contacts with the bottom or prop wash near the bottom, then as to this criteria, concerning marine productivity and recreational value, the project will be contrary to the public interest also. To the extent that nursery areas for fish and other valuable marine organisms are destroyed, the recreational value in terms of quality of fishing will certainly be diminished. The "current condition and relative value of functions" being performed by the area of marine habitat affected by this project must also be considered. In a like vein, this particular area constituting dense growths of seagrasses has a relatively high functional value as a marine habitat and, particularly, a nursery for marine animals. This current condition and value of the area should be accorded a fairly high status in weighing and balancing the various considerations used in determining whether the project is or is not contrary to the public interest. If the boats which are to use the marina upon its construction and operation are permitted inside the grass bed area, roughly within 500 feet of the shore, then clearly the considerations mentioned above will be the subject of adverse effects caused by the boats' operation which in turn is a direct result of the installation of this marina, the dock and the slips. In view of the reasonable likelihood of the project causing some of the adverse effects mentioned above, resulting from contact by boat propellers and boat hulls with the grass beds or erosive prop wash caused by operation of boats in water so shallow that the propellers are too near the bottom, the Applicant has agreed to a condition which will effectively remove boats from the seagrass bed area, provided it is strictly enforced. That condition would provide that boats and the slips in which they would be moored cannot be landward of 600 feet off shore of the mean high water line along the sides of the seaward extending dock. All boat slips are to be located seaward of that point. The Petitioners, however, raised a valid point that, the dock being so long, the natural tendency of boat operators would be to moor their boats along the sides of the dock as close into shore as boat operation is possible in order to more easily load and unload their boats. In order to prevent this problem from occurring, therefore, an additional condition should be imposed on the permit which would provide that the sides of the dock be enclosed by a fence out to the 600 foot mark and of such a configuration and type as to prevent boat operators from mooring boats to the sides of the dock and gaining ingress or egress from their boats on the dock shoreward of the 600 foot point mentioned above. In other words, if it is made impossible to enter or leave a boat from the dock in the area of the seagrass beds, this would substantially reduce the likelihood that the seagrass beds would be damaged by boats using the dock. Additionally, prominent signs should be posted on or in the vicinity of the dock announcing the necessity to avoid operating boats landward of the point mentioned above and the necessity of avoiding contacting the seagrass beds with boats or boat propellors. If this condition is adhered to and strictly enforced, as even Petitioner's expert witness concedes, it will prevent the chief source of adverse effects upon the public interest. An additional consideration in determining whether or not this project is contrary to the public interest concerns its effect upon navigation. This has already been discussed in the above Findings of Fact. Since this would be the only dock in the immediate area, it is found that the presence of the dock, even though it extends a significant distance seaward of the shore line, will still not pose a significant impediment to navigation. Additionally, as has been pointed out above, the public interest might be served in a positive way by the installation of the dock to the extent that it might prevent shrimp boats and other fishing boats pulling nets from using the shallow seagrass area which will help prevent uprooting and other damage to the grass beds caused by the nets and associated fishing gear. Finally, it should be pointed out that to a certain extent the project will positively serve recreational values and the public welfare, in the context of balancing the various public interest considerations, because at least half the boat slips will be reserved for public use and because the addition of such a marina or docking facility will enhance the public's ability to obtain recreational value from the State waters involved in East Bay by improving marine access to those waters for fishing, boating, skiing and other purposes. In short, reasonable assurances have been provided that the project is not contrary to the public interest.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is, therefore RECOMMENDED that the application of John E. Bravo for the dredge and fill permit at issue be GRANTED, provided that the terms and conditions enumerated in the above Findings of Fact are incorporated in the permit as mandatory conditions. DONE and ORDERED this 29th day of July, 1987, in Tallahassee, Florida. P. MICHAEL RUFF 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 29th day of July, 1987.
The Issue On June 7, 1991 the Department of Environmental Regulation (DER) released its intent to issue Permit No. DC05-194008, authorizing Florida Cities Water Company (FCWC) to construct a 300-acre restricted public access spray irrigation system for the land application of treated domestic wastewater (Sprayfield Permit). And, on August 6, 1991 DER released its intent to issue Permit No. MS05-194894, relating to stormwater management and management and storage of surface waters (MSSW Permit) for the sprayfield site. Petitioners Brevard Groves, Inc. and H & S Groves, Inc. (Groves), Parrish Properties, Inc., Parrish Management, Inc. (Parrishes), Atico Financial Corp. (Atico) and David and Eleanor Shreve (Shreve), each requested a formal administrative hearing challenging the issuance of the sprayfield permit. Groves requested a hearing challenging the issuance of the MSSW Permit. The ultimate issue is whether FCWC is entitled to these permits.
Findings Of Fact FCWC is a private utility company, with headquarters at 4837 Swift Road, Suite 100, Sarasota, Florida, 34231. FCWC's Barefoot Bay Wastewater Treatment Plant (the WWTP) provides water and wastewater service to the Barefoot Bay development in southern Brevard County, Florida. DER, 2600 Blair Stone Road, Tallahassee, Florida 32399-2900, is an agency of the State of Florida which regulates domestic wastewater treatment and disposal facilities and permits their construction and operation. For domestic wastewater projects, DER is also charged with reviewing applications for stormwater management and management and storage of surface water pursuant to an operating agreement between DER and St. Johns River Water Management District. David and Eleanor Shreve are beekeepers who live approximately a quarter-mile from the proposed sprayfield. They maintain beehives in the groves and woods surrounding the proposed site. The remaining Petitioners own citrus groves that are adjacent to, or in the immediate vicinity of the proposed site. These groves are producing and are actively maintained. The WWTP has a treatment capacity of 0.9 million gallons per day (MGD). As of July, 1990, the WTTP was treating and disposing of effluent from approximately 4,200 residences in the Barefoot Bay development. At buildout, within the five-year life of the Sprayfield Permit, the WWTP will serve 5,000 residents, and will generate approximately 0.6 MGD of wastewater. Disposal of treated effluent is presently achieved by a 40-acre sprayfield, storage ponds and direct discharge of pond overflow to the San Sebastian Drainage District Canal (Canal). In 1986, DER issued FCWC a warning notice to the WWTP regarding an unlawful discharge to the Canal. FCWC met with DER to discuss options to correct the discharge. In 1988, FCWC entered a Consent Order that would allow FCWC to discharge treated effluent into the Canal until a deep injection well could be built for alternative disposal. FCWC also discussed other alternatives with DER, such as golf course irrigation. The Consent Order was amended in 1991 to provide for land application in lieu of deep injection. In accordance with the amended Consent Order, FCWC has submitted monthly monitoring reports to DER, for the WWTP and for the storage (percolation) ponds. DER has never issued a notice of violation to FCWC for failure to comply with monitoring in the Consent Order. The Site The proposed sprayfield site is divided into two large tracts, the "northern parcel" and the "southern parcel." The site is primarily citrus groves. Although some citrus trees were damaged by a freeze in recent years, most are still viable. Most of the areas between the trees and limited areas without trees are covered with dense grasses and weeds. The site, and the surrounding groves, have been significantly altered to provide sufficient drainage for citrus trees, which require well-drained conditions. The area is covered by shallow ditches (swales), between mounded rows of earth comprising beds for the trees. These citrus mounds, created by soil cast up during excavation of the swales, occur on 60-foot centers and rise 2 1/2-3 feet above the bottom of the swales. The swales have pipes at each end, which discharge into an agricultural collection ditch or the Canal. Each block of citrus is surrounded by a collection ditch some 8-10 feet deep. All collection ditches ultimately discharge into the Canal, which borders the site on the north and is approximately 20 feet deep and 100 feet wide. The collection ditches and Canal prevent the entrance of offsite surface water run- off into the site and receive surface water run-off and groundwater seepage from the site. The Sprayfield Project The project is proposed in two phases. Phase I meets total annual effluent disposal needs of 0.55 MGD, using both the proposed sprayfield and the existing 40-acre sprayfield, which will continue in operation for both phases of the project. Phase II meets the total annual effluent disposal needs of 0.6 MGD at build-out. This results in an average annual application rate of 0.54 inch/week or approximately 28 inches per year on the proposed sprayfield. The project is designed to eliminate the current discharge to the Canal. The effluent will be given secondary treatment with basic disinfection. The treated effluent will be pumped from the WWTP to storage ponds and then to the proposed sprayfield. The existing ponds will be retrofitted as storage ponds for Phase I. An additional storage pond will be constructed at the proposed sprayfield for Phase II. The spray irrigation system will operate primarily with four traveling gun sprinklers. Two sets of fixed-head sprinklers will also be used for the two small triangular portions of the site. The traveling sprinklers will be operated for approximately 5.9 hours/day during Phase I and 6.5 hours during Phase II. The four traveling sprinklers will run simultaneously on four of the thirty-three travel lanes (tracks) located between the swales covering the site. Ordinarily each track will be sprayed every eighth day. To make up for days when irrigation is not possible, additional disposal capacity can be obtained by operating the sprinklers for extra shifts on tracks not previously irrigated that day. The site will be mowed regularly, and any accumulated grasses or debris will be removed. Any areas presently in weeds, or the areas not covered by vegetation are reasonably expected to fill in with dense grasses when irrigation commences. Maintaining the grass cover in the swales will prevent erosion of soil and debris into the swales and reduce the need for maintenance of clogged swale outlet pipes. The system is designed and will be operated to avoid ponding or direct surface run-off of sprayed treated effluent. However, there may be some very limited potential for droplets of treated effluent clinging to vegetation being washed into the swales by a heavy storm event immediately following an application. Therefore, the sprinklers will not be operated when the water table is closer than four inches from the bottom of the swales. Operators will know when to spray by reading automatic groundwater elevation monitoring gauges installed in several places throughout each block of citrus, including the middle. In addition, an automatic device will shut off sprinklers during a rainfall, so that no significant amount of treated effluent will leave the site mixed with stormwater. The site is bordered on three sides by groves and on one side by undeveloped vacant land. The width of the proposed buffer zone from the sprayfield wetted area to the site property line is at least 100 feet, as required in Rule 17-610.421(2), F.A.C., and is substantially wider for extensive lengths of the project border. The buffer is approximately 130 ft. wide on the eastern boundary of the northern parcel, approximately 250 to 235 ft. wide on the western boundary of the northern parcel, and approximately 225 to 160 ft. on the western border of the southern parcel. The distance between the wetted area and adjacent property owners' boundaries is much greater than 100 ft. for other portions of the sprayfield borders due to linear features that provide additional buffering. It is over 200 ft. from the wetted area to the nearest property owner on the northern border of the northern parcel because of the San Sebastian Canal, and 160 ft. on the southern border of the northern parcel and the southern and eastern borders of the southern parcel because of the 60-foot wide Micco Road right-of-way. Aerosal Drift and Other Off-Site Impacts While Petitioners allege that their groves would be contaminated by aerosol drift from the site, they presented no expert or other competent, substantial evidence on the extent or volume of such drift. FCWC air modelling expert, Dr. Robert Sholtes, used the EPA Industrial Source Complex Model (ISC), the most commonly used predictive model in the air pollution community, to evaluate the project's aerosol drift. While the sprinklers are planned to be operated a maximum 6.5-hour shift, a conservative 7.0-hour shift was used. Other data inputs to the ISC Model were hourly windspeeds at the Daytona Beach weather station for five years; sprinkler nozzle size and pressure; and droplet size, distribution and settling rates obtained from the American Society of Agricultural Engineers. The model yielded the annual average deposition of sprayed effluent in grams per square meter (gm/m2) outside the wetted area for one sprinkler as it moves along its track. The accumulated deposition off the site property line, considering operation of all tracks, can be predicted using these results. Because heavy deposition of droplets settles out fairly rapidly, the aerosol from tracks farther into the site does not significantly affect the maximum impact shown for one track. Due to the prevailing east and west coastal winds, heaviest deposition will occur off the eastern and western property line of the site. The volume of treated effluent that will be blown offsite is not substantial. The greatest volume is approximately 1000 millimeters/square meter/year (ml/m2/yr) off the eastern property line out to approximately 50-75 feet, and 500 ml/m2/yr off the western property line out to approximately 75 feet. A maximum of 100 ml/m2/yr is predicted and a maximum of 50 ml/m2/yr is predicted off the southern and northern lines, respectively. In practice, volumes of aerosol drift off-site will be below the predicted levels in areas where trees occur in the buffers. Most significantly, there are existing rows of citrus trees along the eastern border of the northern parcel within the buffer area, which is the area of heaviest predicted drift. In addition, aerosol drift will be minimized by operating procedures. Wind speed and direction will be monitored at the site. If the wind is over 20 miles per hour, there will be no spraying. For winds of lesser speeds, the spray tracks on the edges of the sprayfield will not be used during a strong directional wind, e.g., for a wind blowing east, the track on the eastern border will not be utilized. The tracks are on approximately 240-foot centers. Therefore, elimination of spraying for the track on the edge of the site will have the effect of withdrawing the aerosol drift deposition pattern 240 feet further into the sprayfield. Considering that the farthest extent of the maximum 1000 ml/m2/yr levels of drift is 75 feet, such a program will be very effective in minimizing drift. Because no motors will be required to operate the site, significant noise is not expected. The treated effluent will not contain significant amounts of odor-causing constituents, and odors are not expected. Finally, lighting is not planned on the proposed sprayfield, so this is not expected to be a source of offsite impact. Assurances for Proposed Application Rate A determination of the site's ability to accept treated effluent at the maximum proposed application rate of 0.54 inch/week without adverse effects was based on (1) the hydraulic loading capacity of the site to receive the applied water, considering soil permeability and other physical site conditions, and (2) the allowable nitrogen loading rate, considering the ability of the vegetation to uptake the nitrogen contained in the treated effluent. The U.S. Environmental Protection Agency (EPA) publishes a general manual for technical assistance in designing land application systems across the United States. This manual, "Land Treatment of Municipal Wastewater - Process Design Manual" (EPA Manual), is cited as a general technical guidance source in DER Rule 17- 610.300(4), F.A.C. The EPA Manual contains formulae for the calculation of both the hydraulic loading capacity and the allowable nitrogen loading rate. The EPA Manual recommends use of the more restrictive of the hydraulic loading capacity or the allowable nitrogen loading rate as the hydraulic loading rate for the project. Hydraulic Loading Capacity. A hydraulic loading capacity of 0.63 inch/week for the proposed sprayfield was determined based on field exploration, laboratory testing, hydrogeological conditions and engineering evaluation, summarized in a report included in the application. This 0.63 inch/week hydraulic loading capacity is above the maximum proposed application rate of 0.54 inch/week and substantially below the maximum rate of 2 inches/week allowed by DER Rule 17-610.423(4), F.A.C. EPA Equation 4-3 for hydraulic loading capacity balances the volume of water that enters the site with the volume of water that leaves the site. Values in Equation 4-3 are evapotranspiration, which is the water released to the atmosphere from soil surfaces and by vegetation (ET); precipitation rate (rainfall); and Pw, which is water removed by vertical percolation downward through the soils. Due to the high vertical permeabilities of the sandy soils at this site, unrefined use of EPA Equation 4-3 would give a very high hydraulic loading capacity for this project, on the order of 10 times that proposed by FCWC. Therefore, a more detailed input/output water balance formula was used to determine annual hydraulic loading capacity (applied effluent in the formula) of 0.63 inch/week: rainfall + applied effluent + groundwater inflow = evapotranspiration, + groundwater outflow + surface run-off + evaporation + irrigation losses. The average annual rainfall, based on data from the U.S. NOAA weather station at Melbourne, is 48.17 inches. Due to the isolating effect of the deep ditches surrounding the site, groundwater inflow is considered to be so negligible that it was not assigned a value for the equation. ET, based on standard scientific references, is 45 inches/year for citrus trees. An additional 20 inches/year loss is attributable to grasses covering soil surfaces. In lieu of vertical percolation, groundwater outflow laterally through the surficial aquifer was projected to be 1.8 inches per year, based on hydraulic conductivity and soil permeabilities for the site. Surface run-off of stormwater was estimated to be 10 inches per year. Irrigation losses were estimated at 15% of the amount of applied effluent. Pond Storage Capacity. The proposed application rates for the two phases of the project are annual averages. The volume of storage needed for occasions when conditions preclude application must be determined. DER requires the calculation of storage by analytical means for the 10-year rainfall recurrence interval, using 20 years of rainfall data, and accounting for all water inputs on a monthly basis, using site-specific data. A minimum storage volume equal to three days application is required. Rule 17-610.414 (2), F.A.C. Calculations presented in the application met these requirements and showed storage needs of 8.08 million gallons (MG), or approximately 15 application days' volume, for Phase I; and 15 MG, or 25 application days for Phase II. Additional storage calculations, reflecting the monthly variations of wastewater inflow due to the seasonal population, were prepared for Phase I. These calculations reflected the same storage requirements. Petitioners' Allegations Regarding Application Rate and Storage Although they had prepared no analyses, performed no calculations, conducted no laboratory tests and undertaken only one field test (test hole for groundwater level), Petitioners' witnesses asserted that site conditions precluded successful operation of the sprayfield at the maximum proposed application rate of 0.54 inch/week. They asserted that swale pipes would plug and a clay "hardpan" at the bottom of the swales would prohibit percolation of stormwater. Thus, the swales would be full of water for long periods and further application would be precluded. They also asserted that significant volumes of treated effluent would leave the site as run-off. They alleged treated effluent would enter the swales directly from accumulation of spray and indirectly from seepage from the sides of the citrus mounds. Finally, Petitioners asserted 15 days of storage was inadequate because the site would be too wet for application for at least a month. FCWC presented testimony and evidence based on site reviews, numerous field and laboratory tests, computer modelling, and calculations that successfully refuted these allegations. Petitioners' expert in grove management and local soil conditions, Mr. Burnette, stated that extremely wet conditions required pumping of swales for weeks at a time in nearby groves. FCWC's experts asserted that the proposed sprayfield site currently has, and will continue to have, under proper maintenance, much better drainage than Mr. Burnette's groves, where regular grading of swale inverts and herbicide applications denude soil and cause erosion which plugs pipes and backs up water in the swales. In addition, unlike the situation described in Burnette's groves, the proposed site contains no swales that are lower in elevation than the collection ditches, thereby facilitating stormwater run-off. The top layer of soil comprising the citrus mounds and the swales is relatively clean sand. Petitioners' so-called "hardpan" is a slightly clayey to clayey fine sand layer which separates the upper sand from a thick layer of very clean, beach-type sand. FCWC geotechnical experts determined the clayey sand layer was 18 to 24 inches below the bottom of the swales. Without any field testing, Petitioners' expert hydrogeologist, Mr. Oros, asserted that the clayey sand layer was at the bottom of the swales. In contrast, Mr. Burnette stated that the clayey sand layer occurs four to eight inches below the bottom of the swales on the adjoining groves, where the graded swales are 10 to 14 inches deeper than the shallow swales on the proposed sprayfield site. Thus, Mr. Burnette's testimony supports the FCWC conclusion that this layer is found up to 2 feet below the swales on the proposed site. Moreover, contrary to Petitioners' assertions that the layer acts as a "hardpan", water can pass relatively freely through it and the water table will not "perch" above it. The U.S. Department of Agriculture Soil Conservation Service (SCS) reports a permeability value for this soil type of one to 12 feet per day. Dr. John Garlanger, FCWC expert in subsurface investigation and soil mechanics, conducted a field inspection of the soil and reviewed grain size distribution analyses. He determined that the permeability of the clayey sand layer is about one foot of water per day. Petitioners' expert hydrogeologist concurred that the layer could have this permeability rate. Soil is at the "wilting point" when its water content is too low for plants to transpire additional water. Soil is at "field capacity" when added water "fills up" the soil and it becomes saturated. The "water table" is the level at which the soil is totally saturated. Petitioners erroneously assert that 90% of the 0.54 inch of treated effluent will travel straight down to the water table. Instead, due to capillary action, the first foot of the sandy soil at the site can store about 0.6 inch of water between the wilting point and field capacity. If there is no rain between applications, 100% of the 0.54 inch will be transpired by vegetation out of the first foot of soil. This "resets" the soil moisture content to the wilting point in preparation for another application. If heavy rains cause the soil to remain at field capacity rather than returning to the wilting point through ET, the soil can still absorb up to 2.25 inches of water per foot, or three-fourths to one inch of water per four inches of soil, before it reaches saturation. Therefore, even if the soil is saturated up to 4 inches below the swales, the top 4 inches of soil will still absorb the 0.54 inch of treated effluent without reaching total saturation or causing any run-off. If subsequent heavy rains saturate the remaining soil and raise the water table to the bottom of the swales, the excess rainwater which falls on the saturated surface will run off as stormwater, and most of the treated effluent will remain stored within the soil. Furthermore, because the water table is proposed to be measured at centers of the blocks where, due to distance from the drainage ditches, the water table is closest to the surface, soil storage capacity across the site will exceed these projected levels. Petitioners' experts also asserted that if it rains after the 0.54 inch application, the groundwater will "mound" up below the citrus mounds, creating a hydraulic gradient or head differential (between the water table under the citrus mounds and the water table below the swales) sufficiently great to cause the treated effluent in the mound to flow toward the swales and seep into them from the sides of the citrus mounds. Mr. Golding admitted that such seepage would not occur when the groundwater table is below the bottom of the swales. Nevertheless, he opined that seepage of treated effluent would be considerable because he believed, based on opinion and experience alone, that the water table would be at the bottom of the swales or higher for at least 30 days straight in a "wet year." FCWC's experts successfully refuted these assertions. A significant portion of the treated effluent falling onto the citrus mounds will be stored in the soil as described above. The treated effluent (only applied when water level is 4 inches below the swales) that actually reaches the water table will cause only a very slight "water mound" (only 2 inches in 30 feet) which will not produce any appreciable "head" or lateral flow to the swales. On only three occasions (a total of 8 days) during the wettest year in ten did the "water mound" rise above the bottom of the swales resulting in any groundwater seepage from the citrus mounds into the swales. Thus, during the entire wettest year in ten, less than one-half of 1% (0.12 inch of the approximately 28 inches) of annual applied treated effluent, very diluted with groundwater, might seep from the mounds into the swale. Contrary to Petitioners' expert's assertion that the seasonal high water level (SHWL) was not provided by FCWC, this information was supplied in the application and was reaffirmed by calculations of Dr. Garlanger at rebuttal. The importance attached to the SHWL for this project was not adequately explained by Petitioners. FCWC experts explained that the SHWL is the average (NOT maximum) height of the groundwater during the two to six wettest months of the year. Because the water table varies throughout the year, it is the calculation of the position of the water table from month to month that is significant and is required by DER. This monthly changing water table was the basis of storage water balance calculations contained in the application. Even though the monthly storage calculation in the application meets the DER/EPA requirements, Petitioners' witnesses asserted that the application did not indicate how many days the water table would rise to four inches below the swales and thus how many days spraying was precluded and storage was required. Dr. Garlanger analytically calculated the water table beneath the site, using Darcy's Law, and known parameters at the site, such as the depths of the ditches, the geometry and relative distances, and the thickness and permeability of the soil layers. Thus, although never required for any of the 100 land application projects he has evaluated, Dr. Garlanger performed computer modelling and calculations to predict the daily level of the water table beneath the swales for both Phase I and II during the wettest year in ten. Water inputs in his model included treated effluent and daily rainfall from an actual year (1969) when rainfall reached the levels of the statistically wettest year in ten. Water losses were soil storage, ET, distribution losses, deep percolation and run-off. Treated effluent was not applied when the model predicted that the water table would be higher than four inches below the bottom of the swales and when there was significant rainfall (more than one-hundredth of an inch). This modelling predicted that 6.1 MG/11-day storage was needed for Phase I. Thus, the project as proposed has substantially more storage than needed, with a proposed 8.1 MG/15-day storage. The model produced similar results for Phase II, showing a total 10.1 MG/18-day storage need compared with the proposed 15 MG/25-day storage. Petitioners also challenged various "irrigation efficiency" figures used by FCWC experts. All water leaving a water source, in this case the WWTP, does not reach the roots of the crops for which it is intended. "Irrigation efficiency" expresses this fact as the percentage of water pumped that is used by the vegetation. In the monthly storage water balance calculations the applicant used an "irrigation efficiency" of 70% of the total applied treated effluent, which is recommended in IFAS Bulletin 247 and in the USDA, SCS, "Florida Irrigation Guide"; 15% of the applied treated effluent was attributed to "irrigation losses" in the calculations in the application to determine the hydraulic loading capacity; and Dr. Sholtes stated that data he used indicated that 94% of "the water that came out of the nozzle reached the ground" within the wetted area of the site and the remaining 6% was aerosol drift and evaporation. Petitioners' expert questioned whether an irrigation efficiency of 70%, 85% or 94% should have been used and suggested that the calculations should be redone. The expert misunderstood the terms, comparing the proverbial apples and oranges. With a 70% irrigation efficiency, 30% treated effluent is lost to the plants. Only a small portion of this 30% loss is attributable to aerosol drift and evaporation in the air. Most of the 30% treated effluent hits the ground but is still lost to the plants through evaporation of treated effluent intercepted on plant leaves, losses from the distribution system, e.g., leaky fittings at the WTTP, and percolation of water below the reach of plant roots. The "irrigation losses" (15%) in the application include all of those types of losses, except the treated effluent losses through percolation. This approximately 15% of the total treated effluent appeared as a separate value from "irrigation efficiency." Water Quality Assurances Nitrogen Loading Rate. Because nitrogen is generally the constituent of most concern for sprayfields, EPA Equation 4-4, which is intended to produce a conservative result, projects nitrogen loading possible without exceeding the groundwater standard for nitrate. Two FCWC experts calculated the allowable nitrogen loading rate. James Christopher, project engineer and expert in water quality and chemistry, adjusted the EPA equation to reflect stormwater leaving the site, which is a more technically correct refinement of the equation and has the effect of lowering the allowable rate. A "U value" (the variable for rate of nitrogen uptake by crop)of 100 kilograms/hectare/year (kg/ha/yr) was used by James Christopher. Dr. Harvey Harper, another FCWC water quality expert, an environmental engineer, who has taught numerous university courses in wastewater treatment and has been involved in scientific studies of pollution removal, also calculated the nitrogen loading rate for the annual average rainfall and the wettest year in ten. He did not adjust EPA Equation 4-4 for stormwater run-off, because Petitioners had questioned any deviations from the formula. He used a U value of 150 kg/ha/yr, because he considered a value of 100 too low to be realistic. He used the highest nitrogen value in data from the WWTP. Other values he used in the equation were nearly identical to those of Mr. Christopher. The results were an allowable nitrogen loading rate of 0.75 inch/week for a year of average rainfall and 0.93 inch/week for the wettest year in ten. These rates are substantially higher than the proposed gross hydraulic loading rate of 0.54 inch/week. Petitioners' expert, Dr. J. P. Subramani, asserted that a U value of 0 kg/ha/yr should have been used, although he admitted that a site with a U value of 0 kg/ha/yr would be bare sand devoid of vegetation. The U values of 100 and 150 kg/ha/yr used by FCWC were extremely conservative. The EPA Manual provides U value ranges for forage grasses, at a low of 130-225 kg/ha/yr for bromegrass, to a high of 400-675 kg/hayr for coastal bermuda grass. Ignoring the testimony of FCWC witnesses that the grass would be mowed and removed from the site, Dr. Subramani supported his opinion only with the unfounded contrary assertion that the vegetation on site will not be harvested and removed as a crop. Petitioners alleged that discharges from the site would contaminate surface and ground waters and otherwise adversely affect water quality; inadequate renovation of pollutants would take place in the soil; and the receiving waters were already below standards. Petitioners' experts did no studies or analyses, nor did they predict expected concentrations for any parameters for sprayed treated effluent leaving the site as surface waters or groundwaters. Petitioners' exhibits regarding water quality issues consisted of two single-day monitoring reports for the existing WWTP discharge and the Canal and a set of 1990-91 water quality report sheets for the WWTP. FCWC's expert, Dr. Harper, analyzed the project's impacts on groundwater and on surface waters (the Canal) if the treated effluent were to leave the site as surface run-off in the swales, as groundwater seepage into the collection ditches, or as aerosol drift. Based on 1990-91 water quality monitoring of the WWTP's existing treated effluent, Dr. Harper projected the concentrations of parameters of concern for the treated effluent to be sprayed at the site. Although monitoring of heavy metals is not required at the WWTP, he also projected levels for these parameters based on EPA figures and existing data from two larger domestic wastewater treatment plants. Because those two plants have contributions from industrial and commercial components not found at the WWTP, the projections substantially over-estimated heavy metals expected for the WWTP. Groundwater Impacts. Dr. Harper estimated the pollution removal efficiencies for treated effluent traveling through approximately one foot of soil by reference to the EPA Manual and a study he had performed. He then applied these efficiencies to the projected concentrations for the sprayed treated effluent. Even at maximum projected concentrations, the results showed that projected constituents would be at or better than groundwater quality standards after renovation in the soil. Thus, due to low levels of constituents of concern, including those for which no numerical standard is provided in the rules, the project will not cause groundwater water quality violations and will have no adverse effect on the biological functions in the groundwaters directly underlying the site. Contrary to Petitioners' assertions, DER witnesses stated that DER does not interpret provisions of Rules 17-600.530(4) and 17-610.310(3)(c)4, F.A.C., as requiring background groundwater samples in the application. Because research has shown that groundwater quality results for sprayfields are generally very good, DER routinely defers such sampling until after permit issuance. Thus, the groundwater monitoring plan in the application and in the draft sprayfield permit provides that all monitoring wells will be sampled to establish background water quality and results submitted to DER prior to spray irrigation. DER's expert witness in environmental engineering and wastewater land application design, Christianne Ferraro, as well as John Armstrong, DER's environmental specialist in site contamination clean-up, stated that they had reviewed groundwater monitoring currently provided by FCWC for the WWTP. They found no nitrogen violations. Surface Water Impacts. The preponderant evidence showed that treated effluent will not flow directly into the swales. Therefore, FCWC proved it will not leave site as surface run-off. However, in order to project the worst-case water quality evaluation for droplets greatly diluted by rainwater or groundwater which may enter the swales, it was assumed that all treated effluent landing within swales "made of glass" would run off directly into the Canal. In addition, uptake, removal or dilution likely to occur in the collection ditches was ignored. Pollution removal efficiencies for grassed swales (based on a year-long study) were applied to the projected concentrations for the treated effluent. After renovation in the swales, any treated effluent leaving the site would contain concentrations for parameters of concern at or better than surface water quality standards. Therefore, water quality in the receiving surface waters will not be violated. Due to removal efficiencies for soils, the treated effluent leaving the site as groundwater seepage into the collection ditches is expected to meet surface water quality standards. In addition, the trace quantity of effluent (0.12 inch for wettest year in ten) which may seep into the swales will reach the San Sabastian Canal only after being greatly diluted within the groundwater and filtered and purified in the soil in the citrus mounds and grassed swales. Even projecting ten times the amount of aerosol drift predicted for the project, the water quality impact of any sprayed treated effluent entering the Canal as drift is so small as to be insignificant. Ambient Water Quality. The existing discharge is having minimal effect on the water quality of the Canal. Furthermore, by eliminating the direct discharge, the project will reduce the present impacts on the Canal by 92-99%. Nonetheless, Petitioners suggest that the project may further degrade ambient waters which they allege are already below standards. Dr. Harper assessed the ambient water quality characteristics of the Canal, which is Class III fresh surface water and the ultimate receiving water for the site. Even including water quality data for the Canal put in evidence by Groves, the Canal is not currently at or below any state water quality standards for Class III waters, except for occasional Dissolved Oxygen (DO) levels. Levels of DO in sprayed treated effluent are expected to be very high. Even if groundwater seepage into the collection ditches and the Canal from the proposed sprayfield contains low levels of DO due its travel underground, it will not lower levels of DO in the ambient waters because the groundwater will also be low in BOD, which depresses DO. Thus, groundwater seepage is expected to have a neutral effect on ambient DO or to increase DO levels due to its diluting effect on BOD. Groundwater inflow to the site is negligible but outflow occurs at a significant measured rate. The only significant inputs are sprayed treated effluent and rainfall. Therefore, the groundwater under the site will eventually reach a stable condition where its constituent levels are the average of the constituent levels in rainwater and the treated effluent. The treated effluent to be applied on this site is at or above state groundwater standards. Necessarily, regardless of the condition of the existing groundwater it cannot possibly be degraded by the treated effluent to below state standards and may well be improved by it. Thus, FCWC has provided reasonable assurances that Rule 17- 600.530(4), F.A.C., has been met, without monitoring of ambient groundwaters in the application. The deposition of treated effluent will not violate the standard that all waters of the state shall be free from components which, alone or in combination with other substances, are present in concentrations that are carcinogenic or teratogenic to humans, animals or aquatic species or that pose a serious threat to public health, safety or welfare. Human Health Risk and Contamination. Petitioners allege that the sprayfield poses a hazard for contamination of their properties. They produced no witness or evidence of contamination other than experts in grove management, citrus production and management, and Petitioners themselves, who expressed scientifically unsubstantiated fears of the impact of the sprayfield on human health or the marketing of their fruit and honey. FCWC expert Dr. Christopher Teaf, who teaches biology, toxicology and risk assessment at Florida State University and is also president and principal toxicologist with a firm doing hazardous substance and waste management research, determined that the project poses no off-site contamination hazard. Pathogens. Fecal coliform is a standard measure for the health hazards of treated effluent based on an indicator group of microbiological organisms, present in the intestinal tracts of all warm-blooded animals as well as a number of insects and cold-blooded species. These organisms do not themselves ordinarily cause human disease, but may indicate the presence of other pathogenic organisms. Coliform bacteria are common in water bodies in general, and the state limit for these bacteria is 200/100 ml. Rule 17- 302.560(6), F.A.C. The World Health Organization has concluded that levels as high as 1,000/100 ml constitute an adequate standard and will not be associated with human disease. Only extremely limited numbers of bacteria can survive the hazardous journey from the WTTP to the Petitioners' property. First, required chlorination at the WWTP will reduce the coliforms to no more than 200/100 ml. At that level, pathogenic bacteria are negligible, if present at all. Pressures during ejection from the spray heads will cause a 70-90% mortality rate. Once airborne, bacteria will be killed because of temperature, ultraviolet radiation and desiccation. As water drops evaporate, constituents become more concentrated and the drops become toxic environments for bacteria. Bacteria falling to earth are filtered in the first few inches of surface soils. Any organisms borne off site will find that, due to the antibacterial qualities of citrus peel and fruit and the plethora of chemical agents routinely applied, the adjacent groves are an extremely inhospitable environment. Too few bacteria will survive at FCWC's proposed application levels, or at 10 times those levels, to constitute an infective dose and contribute to the incidence of human disease. Thus, treated effluent in the form of aerosol drift will have no adverse effect on the health of humans or otherwise cause contamination of areas adjacent to the proposed sprayfield. Consumption of Fruit. Bacteria are not taken up by the plant roots and the aerosol drift will not have any effect on the actual health of the citrus trees themselves. The minimal deposition from spray will be removed through washing required by governmental standards to remove dirt, grime and other contamination, such as fungicides, herbicides and pesticides applied as a normal practice in the citrus industry. Based on fifteen years of scientific literature, including the EPA Manual, crops irrigated with treated effluent do not contribute to human health problems in populations that consume those crops. With application of treated effluent with bacterial concentrations, even 10,000 to 100,000 times higher than the standard, there has been no incidence of human disease related to the consumption of such crops. Part II of Rule 17-610, F.A.C., "Reuse: Slow rate land application systems; restricted public access;" governs the type of sprayfield proposed by FCWC. Petitioners alleged that, due to the proximity of their groves and beekeeping activities, higher levels of treatment than those in Part II should be required. They argued that "advanced wastewater treatment" (AWT), defined in Section 403.086(4), F.S., would be more appropriate. This statute gives DER the discretion to require AWT when it deems necessary. Section 403.086(1)(a), F.S. However, AWT would not meet the requirements of Part III of Rule 17-610, which governs irrigation ("direct contact") of edible food crops and requires Class I reliability for treatment which is not required for AWT. Section 403.086(4), F.S.; Rule 17-610.460 and 17-610.475, F.A.C. Adjacent land uses were a part of the permit review for this project required in Part II. Buffer restrictions provide protection from the sprayfield so that levels of deposition are negligible compared to those when spray irrigation is applied directly at the food crop site. Thus, by its decision to issue this permit, DER recognized that minimal aerosol drift is not the "direct contact" envisioned in Part III and that because the project did not pose a hazard to adjoining groves higher levels of treatment are not necessary. Aerosol drift from treated effluent will have no effect on human health due to contamination of honey or adverse effects on the Shreve's bees located near the proposed sprayfield. Natural enzymes in unpasteurized honey are hostile to bacteria. The Shreves have never experienced a problem with the existing forty acre sprayfield even though it is accessible to their bees and has been in the area as long as the bees have. Petitioners allege that the sprayfield will attract birds, creating an aviation hazard to airplanes using the grass airstrip owned by Petitioner, Parrish Properties. Mr. Parrish, who is a licensed pilot, asserted that water ponding on the site and the mowing operation will attract birds. Both the proposed sprayfield and the surrounding groves will be mowed and irrigated and thus will provide the same type of mixed grass and citrus tree habitat as presently found in the groves. Therefore, Petitioners are currently attracting the same type and number of birds to their groves as FCWC's proposed sprayfield will attract. FCWC's expert in botany and ornithology, Mr. Noel Wamer, observed no large birds at the site, the existing 40-acre sprayfield or the surrounding citrus groves. He did observe small birds such as northern cardinals, towhees, and warblers, typical of citrus grove habitats. Cattle egrets might also be expected in the groves and the proposed sprayfield, particularly during mowing operations. Wading birds would only be attracted if water remained on the site for approximately one week or more to allow development of aquatic organisms as a food source. Birds present on the proposed sprayfield are very unlikely to fly up and collide with planes. The grass airstrip is used infrequently, with only 12 landings in the past year. For a number of years Mr. Wamer has observed bird behavior at the Tallahassee sewage treatment plant sprayfields near the Tallahassee Airport. The one-half mile distance between the runway and sprayfields in Tallahassee is nearly the same as the distance between the Petitioners' grass airstrip and the site. Planes landing at the Tallahassee airport are at an altitude of between 500 and 600 feet over the sprayfields, the same height as predicted over the site. Regardless of the size of planes, the birds, primarily cattle egrets, do not react, but continue feeding or resting. Stormwater and Surface Water Management Activities. On April 3, 1991, FCWC submitted an application with DER to modify and operate the existing stormwater and surface water management system on the sprayfield site (MSSW system). The Notice of Intent to Issue the MSSW Permit was published in the Florida Today newspaper on July 27, 1991. Minor activities are proposed to improve the existing system: (1) culverts at the ends of swales will be cleaned to restore full flow capacity; (2) obstructions and excess vegetation will be removed from the collection ditches to restore their original flow lines; and (3) any depressions in the swales will be filled and regraded to attain a minimum swale bottom elevation of 20.2 feet above mean sea level. As asserted by DER's expert in surface water management, the stormwater discharges will not be a combination of stormwater and domestic waste sufficient to trigger review of stormwater under DER rules as required by Rule 40C-42.061(3), F.A.C. Considering all proof adduced, particularly that stormwater will be treated to applicable standards in the grassed swales, water quality will not be violated, and the post- development peak discharge will not exceed the pre-development peak discharge from the site, FCWC provided reasonable assurances that the proposed MSSW system would not be harmful to the water resources in the area and would not be inconsistent with the overall objectives of the district. Summary of Findings and Permit Conditions FCWC has established that the sprayfield, as proposed, will meet the applicable regulatory requirements for the sprayfield and MSSW permits. Included in the specific conditions attached to the notice of intent to issue the sprayfield construction permit is the requirement that the site be operated to preclude saturated ground conditions or ponding. (FCWC Exhibit #3, paragraph 13, specific conditions). Witnesses for the applicant described certain proposals to assure this condition is met, and those proposals should be incorporated into the condition. Those proposals include the cessation of spraying during a rain event and the installation of devices to automatically turn off the sprinklers when rain occurs, the cessation of spraying whenever the groundwater level is within four inches of the bottom of the swales, and the installation of ground water gauges to determine when this level is reached. In order to minimize aerosol drift, the applicant proposes to establish wind gauges indicating the direction and speed of wind at the site. It was suggested that spraying would cease when the wind reaches 20 miles an hour, and sprinklers should be positioned to avoid spraying the downwind perimeter of the site when drift is likely to occur. This condition should also be incorporated in the permit. If the operational adjustments cannot be made automatically it will be necessary to require that the plant be staffed at all times that the spray system is turned on, notwithstanding the minimum six hours, five days a week required in Rule 17-602.370, F.A.C. and referenced in the intent to issue. Engineering computations in the application rely on the assumption that the vegetation onsite will be harvested (mowed and removed). Since spray irrigation treatment of wastewater depends on renovation or removal of effluent by the soil vegetation system, periodic mowing and removal of the vegetation should also be included as a permit condition.
