The Issue The issue in this case is whether the Orange County Parks Department is entitled to a dredge and fill permit from the Department of Environmental Regulation for the construction and installation of a boat dock on Lake Down.
Findings Of Fact The Application On November 1, 1989, Orange County Parks Department (Orange County) applied for a dredge and fill permit to construct a floating boat dock in the Town of Windermere on Lake Down. The application, which is dated September 7, 1989, describes the proposed project as a "public improvement of an existing boat ramp facility." The application describes a floating dock attached by short hinged sections to fixed docks that would be affixed, at normal water elevations, to upland. The application explains that the purpose of the dock is to accommodate boats and pedestrians in loading and unloading boats at the ramp. The dock would, according to the application, reduce wave and wakedisturbance action on the existing shoreline and thus reduce the current rate of erosion at the site. The application assures that no existing vegetation would be disturbed except in the area of the fixed docks. According to the application, the floating dock and two fixed docks would measure about 420 feet long by 7 feet wide with several wideouts of about 10 1/2 feet. The dock is designed to moor 15-18 boats simultaneously. The location map attached to and a part of the application shows that the dock would be at the southernmost extent of Lake Down. The survey attached to and a part of the application provides submerged and upland elevations in the vicinity of the proposed dock. The survey states that the water elevation of Lake Down is 98.8 feet. Nothing indicates whether 98.8 feet is the average water elevation or the water elevation on the date of the survey on June 28, 1989. Other portions of the application describe the composition of the dock parts. The only parts in contact with the water would be galvanized steel pilings, which would be jetted or driven not more than 15 feet deep into the submerged bottom, and plastic floats attached to the bottom of the dock for floatation. The application also indicates that construction-period turbidity would be controlled through the use of turbidity curtains. Another diagram attached to and a part of the application superimposes the dock over the submerged elevations. A note on the diagram states that, under "Plan 1 and Plan 2, Orange County would excavate existing grade under floating dock to elev 97.0." The applicant proposed excavation under the dock due to the shallowness of the water under and lakeward of the dock. The diagram depicts a dock that would run parallel, rather than perpendicular, to the shore. The diagram discloses that the proposed dock would begin immediately east of the existing boat ramp. The diagram indicates that the floating dock runs about 390 feet. The elevation at the northwest corner of the west fixed dock is about 100 feet. At what the construction drawings call "average lake elevation" of 99.5 feet, the piling at the northwest corner of the west fixed dock would thus not be submerged. About 15 feet to the east of the northwest corner, where a hinge connects the west fixed dock to the floating dock, the elevation is between 98 and 99 feet. At average water elevation, the shoreside of the floating dock generally ranges from five to ten feet from the shoreline, with extremes of one foot at the southeast corner of the west fixed dock and 17 feet about 220 feet east of this point. The submerged elevations change significantlyunder the 390 feet of floating dock. On the lakeside, where boats would dock, the following elevations exist under the dock at 40 Dock interval 40' 80' 120' 160' Lakebottom elevation 95-96' 95' 92' 93' 200' 240' 280' 320' 360' 390' 91-92' 91' 92-93' 93-94' 96' 96' The submerged elevations are higher (and thus water depths shallower) on the shoreside of the dock, which would not be accessible to boats. For the back of the floating dock, the submerged elevations exceed 97 feet for the westernmost 40 feet and a short segment at the eastern end of the floating dock; the remaining elevations are less than 97 feet. Unlike the west fixed dock, which would stand almost entirely in upland even at average water elevation, the east fixed dock would stand almost entirely in water at the same water elevation. Also, the west fixed dock would be relatively small and run parallel to the shore beside the ramp. The east fixed dock would be oriented in a northwesterly direction from, and perpendicular to, the shore. The northwest and northeast faces of the east fixed dock would be accessible by boats. The submerged elevation under the northwest face, which is between 15 and 20 feet offshore from the average shoreline, is between 95 and 96 feet. The water depth adjoining the northeast face is shallower because the northeast face, although accessible to boats, would runupland, past the average shoreline at 99.5 feet, to an upland elevation of about 101 feet. The rate of drop of submerged elevation is uneven along the length of the proposed floating dock. Water depth increases more rapidly from the center of the floating dock. For instance, at the 200-foot interval from the west end, the elevation drops from about 91.5 feet at the front of the dock to 88 feet at a point ten feet lakeward of, and perpendicular to, the dock. In other words, the water becomes 3 1/2 feet deeper in the first ten feet. The lakebottom drops more gradually at the west and east ends of the proposed dock. For instance, at the 40 increase in depth ten feet out is only about 2 1/2 feet. At the north corner of the east fixed dock, the increase in depth ten feet out is only about 1 1/2 feet. The diagram also depicts the existing boat ramp that would be served by the proposed dock. The ramp, which is oriented in an eastnortheasterly direction from the shore, is less than ten feet north of the proposed west fixed dock. The ramp measures about 20 feet wide upland and about ten feet wider farther out into the water. The elevation of the submerged north corner of the lakeward end of the boat ramp is between 94 and 95 feet. The elevation of the submerged south corner of the lakeward end of the boat ramp is between 95 and 96 feet. The lakebottom isfairly flat at the boat ramp. Over its 40-foot length, the elevation of the ramp changes by only about 5 feet. A separate diagram attached to and a part of the application depicts the floats that would be attached to the bottom of the decking. The floats would be about 18 inches high and draw about three inches of water when the dock is supporting no weight. A 40-inch high railing would run along the back of the dock. However, the railing would not extend along the northwest and northeast faces of the east fixed dock. Thus, nothing would deter a boat from docking along these two faces of the east fixed dock. On November 9, 1989, Orange County filed an application amendment, which contains drawings that eliminate all excavation. The amendment states: "Dock will be relocated if conflict with existing shore occurs." This amendment was filed at the urging of a DER representative, who would not have recommended the application for approval without the change. There are other suggestions in the record that Orange County would be willing to amend its application to locate the proposed dock farther from shore and in deeper waters. However, Orange County did not specifically offer an amendment, and the record offers no indication where the dock would be, if Orange County again amended the application. On June 20, 1990, Orange County informed the Department of Environmental Regulation (DER) by letter that the legal description provided with the application was inaccurate. The letter provides a new legal description and a list of adjoining property owners. Mr. Rosser, Ms. Grice, and Mr. Patterson own property adjacent to the proposed project or reside in close proximity to Lake Down so as to be substantially affected by any material degradation of water quality. The new legal description encompasses only 1.46 acres rather than the 12.16 acres set forth in the original application. The land eliminated from the application is west and north of the existing boat ramp. Orange County plans to make considerable improvements to the existing boat ramp, such as by the addition of substantial parking and a septic tank on the land eliminated from the original application. However, the present application does not request any permit for such work. The Intent to Issue On February 26, 1990, DER filed an Intent to Issue the permit for which Orange County had applied. The Intent to Issue indicates that the permit is to construct a floating dock on Lake Down about 420 feet by 7 feet, plus wideouts, and notes that the request to dredge along the dock had been withdrawn. According to the Intent to Issue, the bank between the north side of Conroy-Windermere Road and the shoreline has eroded, probably as a result of boaters pulling their boats onto shore for temporary mooring. Although DER did not determine the water elevation on the date of the inspection, the Intent to Issue reports that water depths range from a few inches alongshore to about three feet at the shoreside of the proposed dock. The Intent to Issue notes that Orange County is currently trying to condemn the land north and west of the boat ramp to upgrade the launching facility with a larger ramp, picnic area, and parking spaces for between 50 and 100 vehicles. The Intent to Issue finds that the proposed docking facility and its associated boat traffic would not result in violations of state water quality standards nor degradation of ambient conditions in Lake Down or the Butler Chain. Except for limited construction-period turbidity, which could be controlled with a siltation barrier, displacement or disruption of the lakebottom would reportedly occur only during piling installation, and shoreline vegetation would be removed only at the fixed docks at either end of the floating dock. Addressing prop dredging, the Intent to Issue notes: It is not anticipated that damage to the lake bottom will result from boats moving into and away from the dock. If water levels fall to particularly low levels, the county can close the ramp until adequate depth is available again. Addressing the possibility of increased boat traffic on the lake, the Intent to Issue states: It is not anticipated that use of ramp will significantly increase as a result of the proposed construction. Those individuals who are seriously interested in accessing the Butler Chain have done so despite the poor facility currently available. The new dock will provide mooring capability without causing shoreline erosion. Furthermore, the dock will provide a safer place for boatersto walk and wait. Presently, because there is no onsite parking nor mooring available, boaters park vehicles to the east of the boat ramp site in an undeveloped parcel. They then walk west along Conroy-Windermere Road while sharing the road shoulder with vehicles and trailers. The dock, in combination with the proposed (upland) sidewalk won't shorten the distance to be walked but will remove pedestrians from the roadway sooner to the relative safety of the mooring area. The Intent to Issue concludes that Orange County has provided reasonable assurance that the project will not result in violations of state water quality standards and that the project is clearly in the public interest. Thus, DER expressed its intent to issue the permit, subject to various conditions, in the absence of a timely filed petition. Specific condition 7 of the Intent to Issue addresses the issue of prop dredging: When the lake level drops to the point where boats entering and leaving the dock cause damage to submerged bottoms in the immediate area, the county shall close the ramp and dock until the water returns to acceptable levels. Specific condition 8 addresses the County's plans for additional improvements for the boat ramp facility: Issuance of a permit for the dock does not guarantee nor infer issuance of a permit orpermits for further improvements to the county boat launching facility. Additional Findings Regarding Upland Orlando and the more densely populated areas are generally to the north and east of the boat ramp; Orlando itself is about 10 miles away. The center of the Town of Windermere, which numbers about 1400 persons, is to the west of the boat ramp. About 80% of the users of the boat ramp approach the ramp from the east. A small vehicle-maneuvering area adjoins the ramp on the west. After unloading the boat into the water, the driver of the trailer-towing vehicle typically drives east on Conroy-Windermere Road about 1600 feet and parks on the south side of the road in a large unimproved lot. The County's permission to use the lot is terminable by the owner without notice. While the vehicle and trailer are being parked, the person or persons with the boat normally start the engine and idle just offshore from the ramp or moor on the sandy beach immediately east of the boat ramp. After parking the vehicle, the driver generally crosses to the north side of Conroy-Windermere Road and walks along a sidewalk running from the parking area to what would be the east end of the proposed dock. The road and the sandy beach are separated by a thin strip of thick vegetation. Pedestrians continuing westalong the road, past a point across from the east end of the beach, must walk in the staging lane designed for vehicles waiting to enter the maneuvering area. An existing sidewalk on the south side of the road, which runs east of the ramp area, is not used as much because the sidewalk ends almost 800 feet east of the parking area. Pedestrians typically rejoin their boat at some point along the sandy beach immediately east of the boat ramp. When the boat is spotted, the pedestrian cuts through the vegetation on one of four or five paths running at intervals between the north side of the road and the beach. Traffic on these paths has worn them down noticeably from the prevailing elevations on either side. The same pattern is repeated upon the return of the boat, which is temporarily moored onshore to allow the driver to disembark, take the nearest path to the road, walk along the north side of the road to the parking area, cross the road, and return with the vehicle to the boat ramp. Normal summertime usage, when the boat ramp is used more frequently, involves a range of 30-65 boat launchings per day from the boat ramp. However, peak usage is much higher; nearly 400 trailers have been in the parking area at one time. Present upland usage of the boat ramp area is risky. The staging lane mixes pedestrians and motor vehicles towing trailers. The speed limit on Conroy-Windermere Road is 35 miles per hour at the parking area and 30 miles per hour at theramp, so westbound traffic is still moving rapidly past the staging lane. Also, Conroy-Windermere Road, which is an urban collector, is heavily travelled with an average daily traffic count of 9400 vehicles. Pedestrians crossing the road at the parking area 1600 feet west of the ramp must cross 22- 24 feet of highway. Pedestrians crossing the road at the boat ramp must cross about 50 feet of highway due to the presence of the staging lane and a painted median. Upland safety would be enhanced by separating pedestrians from the staging lane. However, the addition of the floating dock would not eliminate the risks associated with upland usage of the boat ramp. Persons still would be required to cross Conroy-Windermere Road, although a proposed crosswalk would reduce present risks somewhat. In addition, the existing sidewalk on the north side of the road would be reconfigured to lead to the floating boat dock, which would be incorporated into the sidewalk system leading toward the center of the Town of Windermere. For some persons using the dock segment of the sidewalk, such as young children and the disabled, close proximity with the water and mooring boats might prove unsafe. Conroy-Windermere Road has existed for many years, but the portion of the road parallel to the proposed dock was added only about 30 years ago. Previously, the road had turned south, but, following a serious traffic accident, the curve was straightened. Large amounts of fill were added to form the roadbed across the southern tip of Lake Down, which consequentlywas cut off from the remainder of the lake. This fill forms the bank leading to the shoreline directly parallel to the proposed dock. The boat ramp has also existed for many years. Years ago, grove trucks drove down to the lake in order to take on irrigation water. From time to time, persons would put in canoes at this point. Until the late 1960's, when Orange County paved the ramp, few if any powerboats were launched from the area or even used the lake. Today, the overwhelming majority of boats using the ramp currently are gasoline-powered motorboats. There are no restrictions on Lake Down as to the size of engine permitted on the lake, and the posted speed limit is 36 miles per hour. The area surrounding the boat ramp features few amenities. Apart from the maneuvering area, staging lane, and ramp itself, the only other improvements are an enclosed portable toilet and a dumpster garbage container. The Town of Windermere operates two boat ramps on the Butler Chain-- one on Lake Down and one on Lake Butler. Use of these ramps is reserved for Town residents and their guests. The remaining boat ramps on the chain are owned by corporations or private associations. Some boat traffic on the lake is from the use of private boat docks owned by persons owning lakefront land. Lake Down and the Butler Chain Designation as Outstanding Florida Waters By report dated January, 1984, DER recommended that the Environmental Regulation Commission designate as Outstanding Florida Waters the Butler Chain of Lakes: Lake Down, Lake Butler, Wauseon Bay, Lake Louise, Lake Palmer, Lake Chase, Lake Tibet, Lake Sheen, Pocket Lake, Little Fish Lake, and their connecting waterways. The January, 1984 report (DER Report), states that the Butler Chain drains into the Upper Kissimmee River Basin. Noting that Lake Down is the northernmost lake in the chain, the DER Report states that water flow in the lakes, which are interconnected by a series of man-made navigable canals, runs from north to south. Reviewing Florida and applicable federal anti-degradation policies protecting high quality waters, the DER Report states: This antidegradation policy is predicated on the principle that resources are so precious that degradation should not occur except after full consideration of the consequences and then only to the extent necessitated by important economic and social development. Scientifically, the principle is a valid one in that history has taught that adverse effects are difficult to predict. As scientific knowledge grows, previously unknown effects are discovered, and it is prudent to preserve our natural resources in the face of the unknown. DER Report, January 11, 1984 memorandum from DER to Environmental Regulation Commission, page 4. The Butler Chain covers 4700 acres. The largestlake is Lake Butler, which consists of 1665 acres. Lake Down, which is the third largest, consists of 872 acres. Depths of the lakes range from 15-30 feet. According to the DER Report, the upper seven lakes are oligo-mesotrophic with low productivity, high water clarity, and deeper waters. The lower three lakes (Sheen, Pocket, and Fish Lakes) are mesotrophic, with moderate productivity, high coloration of water, and shallower waters. The DER Report states that the water quality of the lakes is excellent. Lake Down had the highest level of dissolved oxygen: 7.1 mg/l. Biochemical oxygen demand was extremely low, in most cases, including Lake Down, less than 1.0 mg/l. Lake Down also had the lowest presence of chlorophyll a, which is a measure of the presence of algae, and a higher degree of biologically diversity, which is typical of a clean, soft-acid lake, according to the DER Report. The DER Report concludes that: An OFW designation will preserve the present environmental values of the Butler Chain of Lakes without any important environmental costs. The existing ecosystem and recreational use of the lakes is dependent upon the maintenance of sufficiently high levels of water quality, which an OFW designation would help to ensure. Id. at 23. The DER Report also includes a May, 1975 report of the Orange County Pollution Control Department, which concedes that the Butler Chain is: one of the few clean water systems left in the Central Florida area. The balance between available nutrient concentrations and the biotic communities has maintained an ecosystem free from the problems that are associated with more enriched systems. The balance is fragile and not well understood. Any activities which would effect this system will express itself [sic] in the aquatic habitat. May, 1975 report, page 4. At the time of its designation, the proposal received numerous endorsements and no objections. On August 16, 1983, The Orange County Board of County Commissioners passed a resolution urging DER to designate the Butler Chain as Outstanding Florida Waters. The Orange County Property Appraiser also supported the designation. In a letter to DER dated September 30, 1983, the appraiser warns that pollution could decrease surrounding property values and cost taxpayers substantial sums for cleanup. Additional Findings Regarding Lake Down Effect of Addition of Floating Dock 53. Neither the submerged galvanized steel pilings nor the plastic floats would allow materials to leach into the lake so as to affect measurably the composition or quality of the water. The increased turbidity during construction of the proposed floating dock also could be controlled so as not to have a significant effect on Lake Down. 2. Relevant Water Levels Water levels have fluctuated considerably in Lake Down. Since January, 1960, to present, the lowest recorded water elevation was 93.86 feet in February, 1987, and the highestelevation was 101.58 feet in August, 1960. Recorded water elevations were less than 97 feet from October, 1977 through August, 1979 and September, 1980 through November, 1982 (during which time the elevation attained 96 feet only six months). Water elevations were between 97 and 98 feet, inclusive, for an additional 29 months during this 31-year period. From March, 1987 through May, 1989, water levels were between 99 and 100 feet, attaining 100 feet only in December of 1987 and 1989. From June through August, 1989, water levels were between 98 and 99 feet. From September, 1989 through the date of the final hearing, water elevations were below 97.8 feet. From mid-March, 1990 through the date of the hearing, water elevations dropped from 97 feet to 96 feet; at the time of the hearing, the water elevation was about 96 feet. When the water elevation is 97.8 feet or less, the canal to Wauseon Bay and, from there, to Lake Butler is impassable to all but very small flatbottom boats. At these times, boat traffic tends to concentrate on Lake Down. Three witnesses for the County and DER testified as to the relationship between the water level of the lake and the operation of the floating dock. One witness for the County testified that the dock would float at 99.5 feet, which corresponds to ordinary high water. The designer of the dock testified that the east and west ends of the dock would cease floating at 96 feet. The DER representative testified that the dock and, pursuant to Special Condition 7, the ramp should beclosed at depths less than 95 feet. The meaning of Special Condition 7 is unclear. First, it is not clear what is meant by boats causing damage to submerged bottoms in the immediate area. Probably, this phrase means actual contact between the prop and bottom, which is known as prop dredging. Thus, boats cause damage to submerged bottoms when the depth of the water is about one foot or less. Special Condition 7 probably ignores the effect of prop wash, where the prop disturbs the bottom, including vegetation, by turbulence rather than direct contact. The second major ambiguity in Special Condition 7 cannot be resolved on the basis of the present record. The question is whether the ramp and entire dock must be closed whenever the water depth under any part of the dock is one foot or less (recognizing that the floats require about one foot of water). In the alternative, Orange County could close only that part of the dock as to which the underlying water depth is one foot or less. It is likely that DER and Orange County have different opinions on this question, with the County taking the latter position. Regardless how Special Condition 7 is construed, it fails to address the damage to submerged bottom that the"floating" dock will do when parts of it begin to ground. When partly grounded, the floating dock will pound up and down on the lakebottom in response to wave action and traffic on the dock. Over 40 feet of the shoreside of the dock will be grounded at water elevations of 97 feet or less, which, without regard to the effect of dock loading or wave action, is the point at which "dock dredging" commences. Water elevations have been less than 98 feet for a total of nearly seven of the last 31 years. The east and west ends of the lakeside of the floating dock would also begin to ground at a water level of about 97 feet. By the time water elevation falls to 96 feet, which existed at the time of the hearing, at least 80 feet of the west end of the floating dock and at least 30 feet of the east end of the floating dock would be grounded, again assuming no wave action and no load on the dock. Additionally, prop dredging would also take place at water elevations of 97 feet immediately adjacent to the dock, at its east and west ends. These water elevations have been experienced for a total of over four of the last 31 years. Another feature of the design of the proposed dock makes it likely that prop dredging will take place regardless of the water elevation. A popular area of the proposed dock would be the east fixed dock because it would be the closest point, by more than 100 yards in some cases, to the existing parking area. Boats could approach the northeast face of the east fixed dock up to an elevation of 101 feet. In other words, except in periods of unusual high water, some boats could and probably would use a section of the fixed dock in the same manner as temporary moorings are made today: in effect, by running up onto the beach. Prop dredging of the bottom would take place if boats approached the northwest face of the fixed dock when the water level fell to about 96.5 feet. The same is true for at least the first 40 feet of the west end of the floating dock. The resuspension of bottom sediment by prop wash would begin at depths of anywhere from 18 inches to seven feet, according to the testimony of the DER representative. Although important variables, such as the composition of the bottom and size and speed of the prop, affect prop wash, significant prop wash takes place for at least three feet under the prop. If three feet were the minimum depth necessary to avoid prop wash and, thus, lakebottom damage, the east 160 feet and west 70 feet of the floating dock would not be usable at water levels not exceeding 96 feet, such as at the time of the final hearing. The significance of lakebottom damage is great under and lakeward of the proposed dock. A thick carpet of bogmoss begins about ten feet offshore, which is roughly where the dock would begin, and continues out into the lake. Bog moss, which captures and retains sediments, would be damaged by the dredging action of the pounding floating dock when it begins to ground and boats using the floating dock at water elevations described in the preceding paragraphs. The phosphorus-rich sediments would then be resuspended in the water column. 3. Ambient Water Quality One of the key elements to preserving the health of Lake Down is to avoid conditions that can lead to the presence of excessive nutrients in the system. The presence of excessive nutrients, which leads to eutrophication, usually occurs because of the increased availability of a limiting nutrient. The limiting nutrient in Lake Down is phosphorus. Thus, a condition precedent to the eutrophication of Lake Down is an increase in the level of phosphorus in the water. The presence of phosphorus in the water can be detected directly, by measuring the phosphorus itself. The presence of phosphorus can also be detected indirectly, by measuring the effects of the nutrient or conditions that may result in the release into the water of additional phosphorus. Indicators of the nutrient levels of a lake include the presence of chlorophyll a, which, as a measure of the amount of algae in the water, is an indicator of the enrichment process. As a lake proceeds from an oligotrophic to a mesotrophic condition or from a mesotrophic to a eutrophiccondition, the presence of algae and chlorophyll a will increase. Indicators of conditions that may result in the release of additional phosphorus into the water include turbidity measurements and clarity data, such as Secchi depths. The sediment found in the submerged lakebottom contains greater concentrations of phosphorus in various organic and inorganic and soluble and insoluble forms than the water column itself contains. When this sediment is disturbed, part of the previously trapped phosphorus is released into the water column. The phosphorus is thereby made more readily available for supplying the nutrients necessary to contribute to the enrichment process, at least until the phosphorus settles back into the sediment where it can be locked up until redisturbed. As relevant to this case, the ambient water quality of Lake Down in the baseline year can largely be assessed in terms of the following data, which are obtained from Orange County Exhibit 13: chlorophyll a: 1.01 ug/l; turbidity: 1 NTU; total phosphorus: .01 mg/l; Secchi depth: 3.5 meters; and pH: 5.97. In the year ending immediately preceding the filing of the County's application, the following data were collected, according to Orange County Exhibit 13: chlorophyll a: 1.59 ug/l; turbidity: .75 NTU; total phosphorus: .01 mg/l; Secchi depth: over 3.5 meters; and pH: 6.36. In the summer of 1990, when the hearing took place, the County's expert collected from Lake Down the followingaveraged data, which are shown on Orange County Exhibits 15 and 17: chlorophyll a: 1.22 ug/l; total phosphorus: .011 mg/l; Secchi depth: over 4 meters; turbidity: 1.0-1.2 NTU's; and pH: 6.97. In the same summer, the Town of Windermere's expert collected the following data from Lake Down: turbidity: 0.92-1.8 NTU's; pH: up to 7.2; and total phosphate: .04-.05 mg/l. The only finding materially different from the findings of the County's expert is the amount of total phosphate. The findings of both experts are credited. The higher finding is supported by, among other things, the recording in the County's records of .037 mg/l of total phosphorus on May 15, 1990, according to Orange County Exhibit 12. In a phosphate-limited, oligo-mesotrophic lake such as Lake Down, total phosphates of .03-.04 mg/l require serious attention in terms of what may be the beginning of a significant degradation of ambient water quality standards. The increase in chlorophyll a is consistent with a trend toward enrichment of the lake since the baseline year. The record establishes the role of motorboat traffic in degrading ambient water quality. Bottom sedimentsoften contain many times more phosphorus than is found in the water column. In the case of Lake Down, sampled bottom sediment contained 11 mg/l of phosphorus, or over 200 times the amount contained in the water column. The phosphorus is trapped in the sediment, which, if disturbed, releases the phosphorus back into the water column. Prop dredging may resuspend the sediments and release the phosphorus, as well as destroy bottom vegetation that tends to retain the sediments. Prop wash also may resuspend bottom sediments, even to depths of seven feet beneath the churning prop. Ultimate Findings of Fact Impact of Proposed Dock on Boat Traffic The proposed floating dock would substantially increase use of Lake Down by motorboats. The dock would generate increased boat traffic on Lake Down because of improvements in navigability in the vicinity of the boat ramp and convenience for boaters in picking up and dropping off passengers and walking between the existing parking area and mooring area. The dock, which would be longer than a football field, is designed to moor 15-18 boats simultaneously. At typical current launching rates, the dock would be capable of mooring, at one time, one-quarter to one-half of the boats using the boat ramp on a given day. DER reasons in the Intent to Issue that boat usage would not increase significantly because persons seriously interested in accessing the Butler Chain have overcome the limitations of the present facility. This reasoning ignores persons more casually interested in accessing the Butler Chain. The above-described improvements in navigability and upland safety will increase the frequency of their visits, which presently may be limited to peak days, such as holidays. If the ratio of serious to casual users corresponds roughly to the ratio of typical boat launches to peak boat launches, the number of casual users may outnumber their more earnest counterparts by six to one. The large capacity of the proposed boat dock suggests that Orange County was targeting these more casual boaters. In theory, Special Condition 7 could have a substantial effect upon boaters' access to Lake Down if the ramp and dock were closed when water elevations fell to 97 feet, at which point much of the shoreside of the dock would already be grounding and boats could not approach the east or west ends of the dock without prop dredging. The ambiguity of Special Condition 7, whose meaning remains elusive even after DER and Orange County have had opportunities to explain its operation, precludes assigning the condition any significance, except as a clear invitation to litigate in the event the floating dock were constructed under the subject Intent to Issue. 2. Ambient Water Quality 79. As relevant to this case, the relevant ambientwater quality of Lake Down is the baseline year. The value of chlorophyll a was 50% lower in the year ending March, 1984, than in the year ending with the subject application. Total phosphorus was about the same, as were Secchi depths. Turbidity was 25% less in the latter year, but the lake had acidified slightly. 3. Changes in Water Quality The water quality of Lake Down has deteriorated since it was designated an Outstanding Florida Water. The amount of chlorophyll a has increased, which is consistent with increased levels of nutrients in the water column. By the summer of 1990, phosphate readings were as much as four or five times greater than in the baseline year and had reached a level that threatens water quality in a phosphate-limited lake such as Lake Down. The role of motorboat traffic in disturbing phosphate-laden bottom sediments and destroying bottom vegetation has been discussed above. The dock dredging at lower water elevations, which are frequently encountered, as well as prop dredging immediately adjacent to the dock, would be especially harmful in view of the thick carpet of bog moss present underneath and lakeward of the proposed dock. 4. Effect of Proposed Dock on Water Quality Orange County has failed to provide reasonable assurance that the proposed project would not lower ambient water quality standards with respect to the effects of dock dredging, prop dredging in the immediate vicinity of the dock, and prop wash associated with increased powerboat traffic on the entire lake. Boats presently mooring on the south shore undoubtedly dredge the bottom with their props. However, the effects are less destructive than the prop dredging that would be associated with the proposed dock, even ignoring the effects of dock dredging and prop wash from additional powerboats. First, fewer boats are using the area now than would be with the proposed dock. Second, although possibly once vegetated, the lakebottom adjacent to the shore is sandy without much vegetation or sediment, so resuspension of sediment and release of phosphorus is less of a problem presently than it would be with the use associated with the new dock. The record does not support a finding that the water quality of Lake Down has been adversely affected by the erosion of rubble and fill from the bank used to construct the realigned Conroy-Windermere Road 30 years ago. Concerns about unfiltered stormwater runoff bypassing the vegetated strip by pouring down the eroded paths into the lake are misplaced. Some governmental entity has installed a stormwater system along aconsiderable part of Conroy-Windermere Road, and the outfall is directly into Lake Down shoreside of the west end of the proposed dock. 5. Effect of Proposed Project on Public Interest Orange County has failed to provide reasonable assurance that the proposed project would be clearly in the public interest after balancing the statutory criteria. The proposed project would achieve a net gain in upland safety, although not without exposing pedestrians using the sidewalk to new risks. The project would also increase boater safety by improving navigability in the vicinity of the boat ramp. However, degradations in water quality negatively impact the issues of public health, the property of others, the conservation of fish and wildlife, and fishing or recreational values, which ironically may be threatened as Lake Down risks becoming a victim of its well-deserved popularity. The current condition and relative values of the functions performed by the lakebottom also militate against a finding that the proposed project, which would be permanent in nature, is clearly in the public interest. The factors in the preceding paragraph outweigh the statutory factors in favor of a finding that the project is clearly in the public interest. In addition to the gains in upland safety and navigability, the other favorable factors are that the proposed project would not adversely affect the flow of water or cause harmful erosion or shoaling. A neutral factor isthat the proposed project would not help or harm significant historic and archaeologic resources.
Recommendation Based on the foregoing, it is hereby RECOMMENDED that the Department of Environmental Regulation enter a final order denying the application of the Orange County Parks Department for a dredge and fill permit to construct a floating dock 420 feet by 7 feet.

The second sentence as to where the boat dock could be built--i.e., further away from theshore to reduce or eliminate dock dredging--is rejected as irrelevant. Orange County did not offer to amend its application, nor even provide a new location for the dock. In any event, the relocation of the dock in deeper water would not reduce the damage done to the lake by the prop wash associated with the additional boat traffic that the new dock would generate.

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

Findings Of Fact Based upon the oral and documentary evidence adduced at the hearing, the following relevant facts are found: Since 1915, the Leisey family has owned or controlled some 710 acres adjacent to Little Cockroach Bay in Hillsborough County. Leisey Shellpit, Inc. now proposes to develop some 55 acres of that property, which has in the past been utilized for row crops, citrus, timbering and mining. The proposed development is to include an 870-boat marina, of which approximately half would be dry storage, located on a 16-acre lake adjacent to the waters of Little Cockroach Bay. The 16-acre lake was created through shell mining operations, and other lakes are to be part of the total project. Leisey proposes to widen and deepen existing mosquito ditches and existing canals or channels to provide access from the proposed marina to Cockroach Bay and the open waters of Tampa Bay. Adjacent to the marina lake, the proposed development also includes a flushing channel, a 250-seat restaurant, a 24-unit resort hotel or motel, a museum, fueling facilities with upland gas storage, an 8-boat ramp launching area, a convenience store, a boat repair facility, a dockmaster's office and 688 parking spaces. The total development further includes a 114-unit apartment complex and 23 single-family residential lots on other lakes nearby the marina lake, a stormwater and agricultural runoff system and a sewage treatment plant. Leisey proposes to widen and convert an existing mosquito ditch between the marina lake and Little Cockroach Bay to a flushing channel in order to accomplish a tidal flushing action in the marina lake. In order to provide access for boats, Leisey proposes to widen and dredge two parallel existing mosquito ditches running southwesterly from the marina lake and an existing channel running east-west along Cockroach Bay Road and extending into the Cockroach Bay channel. These access channels will be dredged to provide a 50- foot wide bottom in most areas with a minus 6 N.O.S. elevation for the bottom of the channels. In areas which do not need dredging, there exists a gentle slope of 6:1. Where excavation is to occur, there will be a 3:1 slope. The total amount of dredging contemplated is 175,000 cubic feet. The majority of the spoil material will be pumped through a polyethelene pipe to the marina lake until that lake is contoured to desired elevations. Secondary spoil sites for any surplus materials are available in lakes owned or controlled by the Leisey family. Depending upon economic and environmental considerations, Leisey intends to use a combination of dredging methods, including suction dredging, dragline dredging, and use of a cutter head dredge. In order to control turbidity, petitioner will utilize earth barricades, silt screens and double silt screens depending upon the type of dredging performed in various locations. The shellpit which is proposed to become the marina lake is not a state water at this time. It will become a state water at the time it is connected to other state waters by the proposed access channels and flushing channel. It would be classified as a Class III water body. The Cockroach Bay Channel which Leisey proposes to widen and dredge has not been dredged in the past. The applicant was unable to predict the extent to which future maintenance dredging would be required if it is widened and deepened to provide access to the proposed marina. The water body areas adjacent to the proposed marina, particularly Cockroach Bay, are presently classified by the Department of Natural Resources as approved for shellfish harvesting, and have been so classified since at least 1975. However, since December 10, 1984, the area has been temporarily closed for shellfish, oyster, clam and mussel harvesting. When a marina is constructed, it is the policy of the Department of Natural Resources to reclassify the area within the marina proper as prohibited for shellfish harvesting and to establish a buffer zone outward from the marina which also would be prohibited for the harvesting of shellfish. The size of the buffer zone is dependent upon the quality, design, hydrography and usage of the marina. The DNR considers a worst-case scenario in terms of potential biological contamination when establishing the size of the buffer zone. In the case of the potential marina, the size of the buffer zone would be hundreds, thousands of yards. It is the policy of the DER to deny a request for a variance if the proposed project would result in DNR closing an area previously approved for shellfish harvesting. Waters approved for shellfish harvesting are classified by DER as Class II waters. Aquatic preserves are designated by the State for the preservation or enhancement of the biological, aesthetic and scientific values of those areas. The boundaries of the Cockroach Bay Aquatic Preserve are described by statute in Section 258.391, Florida Statutes, and such description also defines the boundaries of the Outstanding Florida Water (OFW) classification of the DER. Due to cost considerations, the applicant did not perform a mean high water line survey to demonstrate the proper boundaries of the Cockroach Bay Aquatic Preserve and the corresponding OFW boundaries. The statutory legal description of the Aquatic Preserve was derived from a lease given to the State by the Tampa Port Authority, to which the submerged lands in Hillsborough County had previously been dedicated. That description continuously makes reference to mean high water lines in Tampa Bay and the Little Manatee River. The applicant's professional land surveyor was of the opinion that the waters easterly of the islands offshore the proposed marina, including Little Cockroach Bay, are not a part of the Aquatic Preserve, and thus are not a part of the OFW designation. It was this witness's opinion that the only portion of the project to occur within the Aquatic Preserve is approximately 600 feet of the existing Cockroach Bay Channel to be dredged as an access channel. The DER's expert witness was of the opinion that the statutory legal description does include the waters of Little Cockroach Bay. The intervenors presented testimony that, at the time the description of the Preserve was developed, the Tampa Port Authority did not consider Little Cockroach Bay as a separate water body and intended it to be part of the Cockroach Bay Aquatic Preserve. The Preserve has been managed by the DNR as including the area of Little Cockroach Bay. The proposed marina lake is designed to be four feet deep at its edges and six feet deep In the central portion. An existing mosquito ditch is to be widened to provide a source of new water from Little Cockroach Bay on the incoming tide. At the conclusion of the flood tide, a computer-controlled gate will close, forcing water to exit through the access channels during the ebb tide. A flow directing wall will be installed for the purpose of promoting adequate water exchange in all portions of the marina. Petitioner's plans for the operation of the marina include a prohibition against live-aboards and a `no-head" policy. Fueling at the upland fuel pumps will be encouraged by a price differential. The upland fuel storage tanks are to be protected by barriers and earthen berms. The water side fueling facility is to be protected by a containment boom. In the event of a fuel spill, it is contemplated that the entire marina can be sealed off from outside waters by closing the flushing gates and by closing a turbidity curtain across the access channel. It is contemplated that a dockmaster or assistant will be on-site at the marina to ensure compliance with all rules and to handle any emergencies that may arise. In order to determine the viability of a given basin for use as a marina, it is appropriate to consider the flushing time or residence time -- the time necessary for water in a given system to exchange with waters in adjacent areas outside the system. In marinas that are tidally Influenced, flushing will, in large part, be a function of the tidal forcing. Utilizing a one-dimensional computer model, and assuming that no mixing occurs when water from the flushing channel enters the basin, the applicant predicts that the flushing or residence time of the basin will be approximately 4.2 days assuming a low tide, 5.6 days assuming a mid-tide volume, and 6.6 days assuming a high tide. If one were to assume a completely mixed system, the flushing time would be 8.6 days assuming a low tide, 11.4 days assuming a mid-tide volume, and 14 days assuming a high tide. Over a period of time, the tide level in the proposed basin will actually be represented by the range between high tide and low tide. Rather than assuming a low tide condition, it would be more accurate to use a tidally averaged or mid-tide volume of water. A no-mixing assumption does not take into account dead-water zones within a water basin. In reality, a marina would have some dead zones through the existence of the obstacle effect of objects such as boat hulls. Also, in this proposed marina, the area behind the deflection wall or flow directing wall would be outside the direct flow path and, thus, "dead" water. A one-dimensional model is typically utilized to predict the flushing times of narrow rivers or canals, as it represents tidal flow in only one direction in a straight line. A more appropriate model to utilize in a circular boat marina is a two-dimensional model. The tidal flushing of water bodies whose flow patterns are non-linear are more appropriately predicted by use of a two-dimensional model. The applicant failed to produce competent substantial evidence that the anti-fouling paints used on boats, as well as oils and greases typically produced by boats, would not violate Class III water quality standards in the marina lake and the access channels. It was also not demonstrated that Class III water standards for collform bacteria would be met. These factors are particularly important due to the potential for back flow which could cause marina waters to run back through the flushing canal into Little Cockroach Bay. Also, extreme weather events can force large volumes of water with high concentrations of contaminants out into Tampa Bay. While petitioner's water quality witnesses took samples and reviewed some of the available data base for the area dating back to 1950, the ambient water quality of Cockroach Bay for the period March 1, 1978, to March 1, 1979, was not established. The Hillsborough County Environmental Protection Commission did have monitoring stations in the vicinity of this project during 1978 and 1979. Also, while the petitioner's experts did consider the effects of dredging during construction, the effects of turbidity from future boat traffic were not established. There are currently existing water quality violations with respect to dissolved oxygen in the Class II and Class III waters associated with the proposed project. The more accelerated export of detridal material, as well as the introduction of oils and greases from boats, will cause increased DO violations. The resuspension of fine materials and sediments resulting from dredging and boat traffic in the channels could further lower oxygen demands. The widening and dredging of the access channels proposed by the petitioner will result in the immediate removal of approximately 0.3 acres of seagrasses and about 3.09 acres of mangroves. Most of the seagrass impacts would occur at the western mouth of the Cockroach Bay access channel. Many of the mangroves to be removed are mature, healthy fifteen to twenty- foot trees. Secondary losses of seagrasses and mangroves can be expected from the turbulance and erosion caused by wakes and from propeller damages associated with greatly increased boat traffic in the area. Petitioner proposes to mitigate these secondary losses by providing channel markers, speed limit signs and "no wake" signs in the channel. With respect to the immediate losses, petitioner proposes to replace the 0.3 acres of seagrasses with 0.3 acres of new plantings in the proposed flushing canal. It is suggested that the marina will naturally be vegetated by seagrasses. Petitioner also offers as mitigation for the loss of seagrasses in the dredged access channels the fact that over one acre of hard substrate in the form of pilings and seawalls will be constructed at the marina. It is suggested that this acre would become colonized by sessile attached animals, such as barnacles and oysters, and by red algae, and that this assemblage would become a source of primary productivity and provide a filtering benefit similar in function to grass beds. With respect to mangrove mitigation, petitioner intends to plant six-foot high mangrove trees along the perimeter of the proposed marina lake and along portions of the access channel, and to scrape down an area near the north lake to provide suitable elevations for mangroves and higher marsh vegetation. In total, petitioner plans to replace the 3.09 acres of lost mangroves with 4.25 acres of replanted mangroves. Approximately 80% of the seagrasses in Tampa Bay have been destroyed by development. A significant fraction of the remaining seagrasses are located in the Cockroach Bay area. Seagrass mitigation is highly experimental. No successful seagrass mitigation has occurred in Tampa Bay. The success of replanting seagrasses in the proposed flushing canal is particularly suspect due to scouring, flushing velocities and the potential for poor water quality in the event of a reverse flow from the marina into the flushing channel. The increased salinity in the marina lake could adversely affect seagrasses located there. Propeller cuts are already apparent in Cockroach Bay, as boaters cross the seagrass meadows in order to reach prime fishing areas. An increased amount of boat traffic in the area could be expected to exacerbate such occurences. While mangrove replantings have achieved more success, the areas to be destroyed are mature large systems which provide a considerable detridal feeding base for the animals associated with them, as well as cover for animals, fish and invertebrates that utilize those areas. Many of the types of animals and fish that utilize mangrove areas, as well as seagrass areas, are attached organisms that do not migrate. Mangroves require a stable substrate. The remaining mangrove system in the access channels could change with increased boat traffic, especially in those areas where the slopes are to be reduced to 3:1. The DER does not yet have a promulgated rule regarding mitigation. Its present policy is to evaluate mitigation plans on a case-by-case, site- specific basis. No specific ratio between the impacted area and the mitigated area is required. Instead, it is the policy of DER to analyze various factors, such as the present condition of the area being dredged or filled in terms of the age of the vegetation and the functions being served; proximity of the area to special areas such as Class II waters or an OFW; proximity between the areas impacted and the area planned for mitigation; and past examples of success of the mitigation proposed. DER considers mitigation in relationship to the public interest review standards, and does not consider mitigation when reviewing water quality standards. It is the present policy of the DER to either avoid adverse impacts to healthy seagrasses or to require a lot of" mitigation for those areas which will be lost if the project proceeds. This policy is due to the lack of demonstrated success in replanting or recreating new seagrass communities. While the planting and growing of mangroves has been more successful, it is the policy of the DER to recognize that there is a time lag between the planting and successful growing. When a large, healthy mangrove system is being destroyed and replaced by younger, smaller trees, DER generally requires more than a one- to-one ratio in mitigation. It is the policy of DER to consider the creation of a barnacle habitat as mitigation only when the dredging or filling project itself impacts that type of habitat. Petitioner conducted studies which led to the conclusion that the construction and operation of the proposed project would not reduce the biological integrity or diversity by more than 25 percent. However, given the removal of seagrass meadows and the adverse effects from greatly increased numbers of boats in the area, the applicant did not provide reasonable assurances that the biointegrity standards could be met. Manatees have been sited in Cockroach Bay and the Cockroach Bay boat channel. Due to its seagrasses and shallow waters, Cockroach Bay is one of the most important nursery areas for fish in Tampa Bay. Many wildlife species of special concern have been sited at or near the project site. These include the mangrove terrapin, the mangrove coocou, the brown pelican, the American alligator, the little blue heron, the snowy egret and the tri-colored heron. It is the policy of the DER, when considering the impact of a project upon fish and wildlife, to utilize all federal and state lists of endangered and threatened species. It is highly likely that increased boat traffic and human activity in the area will affect such wildlife. Several locations along the proposed north/south and east/west access channels could pose serious navigational difficulties due to restricted visibility. Given the potential number and sizes of boats in the access channels, manuevering problems can be expected, particularly during weekends. A boater must make a right angle turn where the north/south channel meets the east/west channel. A boat of 25 to 35 feet in length would have difficulty making such a turn in a fifty foot channel at speeds which would not produce a wake. If the vessel suffered engine failure or encountered other traffic at this turn, a hazardous navigational situation could arise. It would take a vessel approximately 20 to 30 minutes to travel at a safe speed from the marina to the mouth of the channel. It is common to observe boaters impatient to get into open waters or return home at the end of the day and navigating at speeds beyond that which is posted or in excess of that which is prudent or safe. Although not part of the application for variance or the instant permit application, petitioner offered evidence of its proposed stormwater management plan, sewage treatment plan, and agricultural runoff treatment plan. These plans are still conceptual in nature and would be the subject of future permitting requirements. Petitioner projects that these implemented plans will actually improve the water quality in the area of the project site. A porous concrete product is to be utilized for parking spaces and throughout the development except immediately adjacent to the marina. This product allows stormwater to pass through it and go into the groundwater, and it is designed to retain and break down oils and greases. Reversed sloping around the marina lake and access channels are to be used to prevent any direct discharge of stormwater. Flow is to be directed away from the marina through grasssed swales into retention ponds and into other isolated lakes. An advanced wastewater treatment plant, with a hyacinth treatment lake, is planned to provide sewage treatment for both this development and the surrounding communities, with an ultimate capacity of 250,000 gallons per day. The treated effluent, after going through the treatment lake will be directed into a rapid exfiltration trench to sheet flow into the mangroves. Petitioner also plans to redirect existing agricultural runoff, identified as being a present source of pollution to water in the area, so that it would go into several lakes and ultimately exit through rapid exfiltration trench sheet flow into the mangroves. In 1983, one of the greatest paleontological finds in this country occurred in one of the mine pits on the Leisey property. Over two hundred and fifty thousand specimens were obtained. Petitioner has entered into an agreement with the Florida State Museum whereby a museum will be constructed near the proposed marina, and displays from the paleontological discovery and other archeological exhibits from the Leisey property will be shown in an educational format. Petitioner has offered to dedicate the museum to the State. Should petitioner receive all permits required for construction of its proposed marina development, the Leisey family has offered to dedicate approximately 54 acres of mangrove lands near Little Cockroach Bay to the Tampa Port Authority or other appropriate entity for preservation purposes. There does appear to be a shortage of available marina spaces in Tampa Bay. However, there is a pending application before DER for an expansion of an existing marina in the vicinity, and other sites along the Bay would be of lesser conflict with existing seagrasses and mangrove systems. If petitioner's marina facility were constructed and operated as proposed, it would serve as a port of refuge to boaters during storms. Petitioner also proposes to reserve two of the eight boat ramp spaces for public safety and environmental agency personnel so that boats can be quickly launched and retrieved in emergency situations. The provision of an eight- space boat ramp and the 432 wet slips and 438-boat dry storage will increase public access to the off-shore waters. The proximity of the Tampa Ship Channel results in direct access to the Gulf of Mexico, and recreational activity will be enhanced by the project. In this proceeding, the burden to demonstrate that the proposed marina project complies with all applicable statutes, rules and policies of the DER and to provide reasonable assurances that the State's water quality standards will not be violated rests with the applicant, Leisey Shellpit, Inc. Due to the location of the proposed project, that burden is heavy and somewhat complicated. Surface waters in Florida are classified according to their present and future most beneficial uses, and water quality criteria have been developed to maintain the minimum conditions necessary to assure the suitability of the water for the designated uses. Section 403.061(10), Florida Statutes, and Rule 17-3.081, Florida Administrative Code. In addition, certain waters, due to their exceptional recreational or ecological significance, have been designated as Outstanding Florida Waters (OFW), with the intent that they be afforded the highest degree of protection. Section 403.061(27), Florida Statutes. A designation of a water body as an OFW is a determination that the environmental, social and economic benefits of the special protection outweigh the environmental, social and economic costs. Rule 17-3.041(:2)(f), Florida Administrative Code. The waters within and adjacent to the proposed project in this proceeding include OFW entitled to the highest protection, Class II waters with the designated use of "shellfish propagation or harvesting," and Class III waters with the designated use of "recreation, propagation and maintenance of a healthy, well-balanced population of fish and wildlife." Rule 17-3.081, Florida Administrative Code. As such, this project is subject to numerous statutory and regulatory requirements. The waters adjacent to the proposed marina, access channels and flushing channels are Class II waters. As such, Rule 17-4.28(8), Florida Administrative Code, governs requests to dredge and fill in those areas. That rule provides as follows: "(8)(a) The department recognizes the special value and importance of Class II waters to Florida's economy as existing or potential sites of commercial and recreational shellfish harvesting and as a nursery area for fish and shellfish. Therefore, it shall be the department's policy to deny applications for permits or certifications for dredging or filling activities in Class II waters, except where the applicant has submitted a plan of procedure which will adequately protect the project area and areas in the vicinity of the project from significant damage. The department shall not issue a permit for dredging or filling directly in areas approved for shellfish harvesting by the Department of Natural Resources. Provided, however, that the staff of the department may issue permits or certifications for maintenance dredging of existing navigational channels, for the construction of coastal protection structures and for the installation of transmission and distribution lines for carrying potable water, electricity or communication cables in rights-of-way previously used for such lines. (b) The department shall also deny applications for permits or certifications for dredging and/or filling activities in any class of waters where the proximity of such activities to Class II waters would be expected to have an impact on the Class II waters, and where reasonable assurance has not been provided that the activities will not result in violations of the applicable provisions of Chapter 17-3, Florida Administrative Code, in the Class II waters. Petitioner does not dispute that the waters are Class II waters. In spite of the fact that a variance from the rule was requested, petitioner contends that the prohibition against dredging in areas "approved for shellfish harvesting by the Department of Natural Resources" is not applicable here because the area is now temporarily closed to shellfish harvesting. In the alternative, petitioner contends that even if these waters are "approved" for shellfish harvesting, it is entitled to a permit to "maintenance dredge an existing navigational channel." This latter contention is without merit. There was no evidence that the access channels proposed to be widened and deepened had been previously dredged. Indeed, the evidence was to the contrary. Consequently, the proposed activity cannot be categorized as "maintenance dredging." Moreover, neither the proposed north/south access channel nor the proposed flushing channel are "existing navigational channels." Petitioner's argument with regard to a distinction between an area "approved" and an area "temporarily closed" to shellfish harvesting is initially logically appealing. However, the argument fails to recognize the purpose of the Class II designated use -- shellfish propagation or harvesting, as well as the DER policy to deny a request for a variance when a project would result in the permanent loss of an area for shellfish harvesting. It was undisputed that DNR establishes buffer zones around marinas within which shellfish harvesting is prohibited, and that the size of the buffer zone is dependent, in part, upon the size of the marina. The area "buffered" would be permanently, as opposed to temporarily, closed for shellfish harvesting. The DER's policy to deny permits or variance requests when the project would result in the permanent closure of a significant area for shellfish harvesting is supported by the remainder of Rule 17-4.28(8)(a), as well as by the purpose for the Class II designation. Thus, under the facts of this case, it is concluded that the prohibition against dredging and filling in areas "approved for shellfish harvesting by the Department of Natural Resources," as set forth In Rule 17- 4.28(8)(a), is applicable and that petitioner has failed to demonstrate entitlement to a variance from that prohibition. Even if petitioner were entitled to a variance, it has not provided reasonable assurances that the short and long term effects of the proposed activities will not violate water quality standards and public interest requirements so as to be entitled to a dredge and fill permit. As noted above, Outstanding Florida Waters are entitled to the highest degree of protection. An applicant for a permit to conduct activities which significantly degrade or are within such waters is required to affirmatively demonstrate that the activity meets the criteria set forth In Rule 17-4.242, Florida Administrative Code. Among those criteria are that the activities be "clearly in the public interest and that the "existing ambient water quality," within the OFW not be lowered as a result of the proposed activity. "Existing ambient water quality" is defined in Rule 17-4.242(1)(d) as the water quality which could reasonably be expected (based upon the best scientific information available) to have existed for the year prior to the OFW designation. The Cockroach Bay Aquatic Preserve was designated as an OFW on March 1, 1979. Rule 17-3.041, Florida Administrative Code. Therefore, the appropriate year for determining the "existing ambient water quality" of that OFW is from March 1, 1978, through March 1, 1979. Petitioner admits that at least 600 feet of the proposed east/west access channel is within the Cockroach Bay Aquatic Preserve. Since a mean high water survey was not conducted by the petitioner, or otherwise presented in this proceeding, the undersigned is unable to render a conclusion regarding the precise boundaries of the Aquatic Preserve or the coextensive OFW designation. It is persuasive that the DNR has managed the Preserve as though Little Cockroach Bay were included within it and that the Tampa Port Authority, from whom the lease to the State was derived, has not recognized Little Cockroach Bay as a separate water body. In any event, at least a portion of the proposed activity will be conducted within an OPW, and petitioner has failed to establish the ambient water quality of those waters for the relevant time period. As a result, petitioner has failed to meet its burden of affirmatively demonstrating that the proposed activity will not lower the quality of that water. While the petitioner did present evidence regarding the current condition of the waters and some historical data was reviewed, there was no affirmative demonstration of the quality of water which existed between March 1, 1978, and March 1, 1979. It simply was not established that petitioner relied upon the best scientific evidence available in its attempt to demonstrate that "existing ambient water quality" would not be lowered by the proposed activity. The operation of an 870-slip marina, along the public boat ramps, will generate a large amount of pollutants. Constant and heavy boat traffic within the marina lake and going in and cut of the area on a daily basis can be expected to continuously resuspend contaminants and pollutants. Given these factors, it was particularly incumbent upon the petitioner to make accurate predictions regarding flushing times, and to provide reasonable assurances that water quality standards would not be violated as a result of the proposed activity. The use of a one-dimensional model, along with the assumptions of no mixing and low tide conditions within the basin, does not provide adequate or accurate predictions with respect to the flushing or residence time of the proposed marina lake. The use of these flushing model computations to make water quality predictions for the lake and channels undermines those predictions. The applicant has failed to provide reasonable assurances that water quality standards, particularly with regard to dissolved oxygen, for Class II and III waters will not be violated on a short and long term basis. Without such assurances, and also considering the loss of healthy seagrasses and mangroves which will result from both dredging and continued boat traffic in the area, the proposed project Is not permittable. As stated In Rule 17- 3.011(5), Florida Administrative Code: 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. When an applicant is unable to meet water quality standards because the existing water quality does not meet standards, mitigation measures which cause net Improvement of the water quality may be considered. Section 403.918(2)(b), Florida Statutes. In mitigation, the petitioner has offered its plans for stormwater management, agricultural run-off and sewage treatment to demonstrate that water quality conditions will be improved by the overall development contemplated. Without a reasonably accurate prediction of the extent to which the proposed project and related activities will cause or contribute to existing DO violations, as well as other violations, in the subject waters, It is impossible to determine whether these mitigation measures will cause a net Improvement of the water quality in the area. In addition, the plans for the proposed stormwater management, agricultural runoff and sewage treatment systems were conceptual in nature. Until more detailed plans are developed, it is impossible to determine whether future permit applications for those projects would be acceptable. The petitioner's mitigation plans for the removal of seagrasses and mangroves is likewise unacceptable. Attempts to replant seagrasses, especially in Tampa Bay, have not been successful and are in an experimental stage. Petitioner's proposed 1:1 mitigation ratio is not appropriate for seagrasses due to the possible failure of its attempts, the proposed location of the replantings, and the expectation of secondary losses from boat traffic, erosion and potential future maintenance dredging. While the replanting of mangroves have a past record of success, a larger than 1:1 ratio would be appropriate to account for the difference in functions between a healthy system of large trees and the replanting of smaller trees, to account for the secondary losses which may be expected from greatly increased boat traffic and to account for the difference in locations between the trees to be removed and the trees to be replanted. An applicant must also provide reasonable assurances that the proposed project is "not contrary to the public Interest" or, in the case of the presence of Outstanding Florida Waters, that the project will be "clearly in the public interest." In making public interest determinations, the Legislature has set forth seven criteria to be considered and balanced, and has allowed applicants to offer measures to mitigate adverse effects. Section 403.918(2), Florida Statutes. The seven factors are: Whether the project will adversely affect the public health, safety, or welfare or the property of others; Whether the project will adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; Whether the project will adversely affect navigation or the flow of water or cause harmful erosion or shoaling; Whether the project will adversely affect the fishing or recreational values or marine productivity in the vicinity of the project; Whether the project will be of a temporary or permanent nature; Whether the project will adversely affect or will enhance significant historical and archaeological resources under the provisions of 5.267.061; and The current condition and relative value of functions being performed by areas affected by the proposed activity. In order to demonstrate that its Mangrove Bay Marina proposal is not contrary to and is clearly in the public interest, petitioner offers its mitigation plans previously discussed with regard to seagrasses, mangroves, stormwater, agricultural runoff and sewage treatment. It is contended that these features of the total project, along with the provision of a secure and well-policed facility, will have a beneficial effect upon public health, safety and welfare and will conserve fish and wildlife and their habitat. It is also urged that its well- marked and maintained channels will Improve navigation and not contribute to harmful shoaling or erosion and will provide for an adequate flow of water. Safe mooring, boat storage and public boat ramps will enhance fishing and recreational values, and marine productivity will not be adversely affected, according to the applicant. Finally, the petitioner offers its museum with educational programs to demonstrate enhancement to significant historical and archaeological resources. There can be no doubt that the applicant has attempted to develop a proposal which will satisfy environmental, as well as social, concerns. It is also true that the marina project would satisfy the need for additional boat slips In the Tampa Bay area. The prime problem is the location of the proposed project. The Cockroach Bay and Little Cockroach Bay areas are relatively undisturbed by development. The area is Important as a research area and as a nursery area for juvenile fish and shellfish. The designation of waters adjacent to and within the proposed project site as Outstanding Florida Waters and Class II waters establishes their importance and govern the manner in which activities therein are to be evaluated. The applicant has failed to provide reasonable assurances that the project complies with water quality criteria and public Interest considerations applicable to these wetlands. The long and short term adverse environmental impacts upon water quality, seagrasses and mangroves are sufficient to justify a denial of the permit application. Those considerations, coupled with the disruption of wildlife habitat, the hazardous design of the marina channels, the destruction of a highly productive aquatic system without appropriate mitigation, and the potential of harming manatees, far outweigh any positive benefits of the project. The paleontology museum, while serving a laudable educational function, will not serve as mitigation for any estuarine loss and the historical and archaeological resources to be considered under Section 403.918(2)(a)6, Florida Statutes, refer to historic properties representing more than 10,000 years of human presence. In short, while the project may provide some advantages with regard to recreation and public safety, its adverse effects upon fish, wildlife, harmful erosion and shoaling, marine productivity and the present condition and value of the functions being performed in the area are contrary to the public interest. Petitioner has failed to demonstrate any overriding public interest that would outweigh these considerations. As a final matter, it was stipulated that Manasota-88, Inc., the Florida Audubon Society, Eagle Audubon Society and Tampa Audubon Society had standing to participate as intervenors in this proceeding. Petitioner's motion in opposition to the intervention status of the Tampa Bay Regional Planning Council was initially denied, subject to that organization presenting proof of its standing at the hearing. The Council failed to produce such proof, and its petition to intervene is accordingly denied.

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

"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.

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

"Water quality standards" shall mean standards composed of designated present and future most beneficial uses (classification of waters), the numerical and narrative criteria applied to the specific water uses or classification, the Florida antidegradation policy, and the moderating provisions (mixing zones, site-specific alternative criteria, and exemptions) contained in Chapter 62-302, F.A.C., and in Chapter 62-4, F.A.C., adopted pursuant to Chapter 403, F.S. "Water segment" shall mean a portion of a water body that the Department will assess and evaluate for purposes of determining whether a TMDL will be required. Water segments previously evaluated as part of the Department's 1998 305(b) Report are depicted in the map titled "Water Segments of Florida," which is incorporated by reference. "Waters" shall be those surface waters described in Section 403.031(13) Florida Statutes. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New There are some high salinity waters of the state that, although they do not have riverine input, nonetheless meet the definition of "estuary" found in Subsection (5) of proposed Rule 62-303.200, Florida Administrative Code, because they are "bays" or "lagoons," as those terms are used in the second sentence of Subsection (5). Rule Chapter 62-4, Florida Administrative Code, which is referenced in Subsections (6) and (23) of proposed Rule 62- 303.200, Florida Administrative Code, addresses the subject of "[p]ermits." According to Subsection (1) of Rule 62-4.210, Florida Administrative Code, "[n]o person shall construct any installation or facility which will reasonably be expected to be a source of . . . water pollution without first applying for and receiving a construction permit from the Department unless exempted by statute or Department rule." Subsection (1) of Rule 62-4.240, Florida Administrative Code, requires that "[a]ny person intending to discharge wastes into the waters of the State shall make application to the Department for an operation permit." An "operation permit" must: Specify the manner, nature, volume and frequency of the discharge permitted; Require proper operation and maintenance of any pollution abatement facility by qualified personnel in accordance with standards established by the Department; and Contain such additional conditions, requirements and restrictions as the Department deems necessary to preserve and protect the quality of the receiving waters and to ensure proper operation of the pollution control facilities. Rule 62-4.240(3), Florida Administrative Code. "An operation permit [will] be issued only if all Department requirements are met, including the provisions of Rules 62-302.300 and 62-302.700 and Rule 62-4.242, F.A.C." Rule 62-4.240(2), Florida Administrative Code. Subsection (1) of Rule 62-4.242, Florida Administrative Code, describes "[a]ntidegradation [p]ermitting [r]equirements." It provides as follows: Permits shall be issued when consistent with the antidegradation policy set forth in Rule 62-302.300 and, if applicable, Rule 62- 302.700. In determining whether a proposed discharge which results in water quality degradation is necessary or desirable under federal standards and under circumstances which are clearly in the public interest, the department shall consider and balance the following factors: Whether the proposed project is important to and is beneficial to the public health, safety, or welfare (taking into account the policies set forth in Rules 62- 302.100, 62-302.300, and, if applicable, 62- 302.700); and Whether the proposed discharge will adversely affect conservation of fish and wildlife, including endangered or threatened species, or their habitats; and Whether the proposed discharge will adversely affect the fishing or water-based recreational values or marine productivity in the vicinity of the proposed discharge; and Whether the proposed discharge is consistent with any applicable Surface Water Improvement and Management Plan that has been adopted by a Water Management District and approved by the Department. In addition to subsection (b) above, in order for a proposed discharge (other than stormwater discharges meeting the requirements of Chapter 62-25, F.A.C.), to be necessary or desirable under federal standards and under circumstances which are clearly in the public interest, the permit applicant must demonstrate that neither of the following is economically and technologically reasonable: Reuse of domestic reclaimed water. Use of other discharge locations, the use of land application, or reuse that would minimize or eliminate the need to lower water quality. Subsections (2) and (3) of Rule 62-4.242, Florida Administrative Code, prescribe "[s]tandards [a]pplying to Outstanding Florida Waters" and "[s]tandards [a]pplying to Outstanding National Resource Waters," respectively. Subsection (4) of Rule 62-4.242, Florida Administrative Code, "prescribe[s] the means by which the Department, upon the petition of a license applicant, will equitably allocate among such persons [directly discharging significant amounts of pollutants into waters which fail to meet one or more of the water quality criteria applicable to those waters] the relative levels of abatement responsibility of each for abatement of those pollutants." Subsection (1) of Rule 62-4.244, Florida Administrative Code, provides that the Department, upon application, may "allow the water quality adjacent to a point of discharge to be degraded to the extent that only the minimum conditions described in subsection 62-302.500(1), Florida Administrative Code, apply within a limited, defined region known as the mixing zone"; provided, that the "mixing zone" does not "significantly impair any of the designated uses of the receiving body of water." Subsection 502(6) of the Clean Water Act (33 U.S.C. Section 1362(6)), which is referenced in Subsection (12) of proposed Rule 62-303.200, Florida Administrative Code, provides as follows: The term "pollutant" means dredged spoil, solid waste, incinerator residue, sewage, garbage, sewage sludge, munitions, chemical wastes, biological materials, radioactive materials, heat, wrecked or discarded equipment, rock, sand, cellar dirt and industrial, municipal, and agricultural waste discharged into water. This term does not mean (A) "sewage from vessels or a discharge incidental to the normal operation of a vessel of the Armed Forces" within the meaning of section 1322 of this title; or (B) water, gas, or other material which is injected into a well to facilitate production of oil or gas, or water derived in association with oil or gas production and disposed of in a well, if the well used either to facilitate production or for disposal purposes is approved by authority of the State in which the well is located, and if such State determines that such injection or disposal will not result in the degradation of ground or surface water resources. Subsection 502(19) of the Clean Water Act (33 U.S.C. Section 1362(19)), which is referenced in Subsection (13) of proposed Rule 62-303.200, Florida Administrative Code, provides as follows: The term "pollution" means the man-made or man-induced alteration of the chemical, physical, biological, and radiological integrity of water. In Chapter 403, Florida Statutes, the definition of "pollution" is found, not in Subsection (2) of Section 403.031, Florida Statutes, as indicated in Subsection (13) of proposed Rule 62-303.200, Florida Administrative Code, but in Subsection (7) of the statute. The "water segments" referenced in the second sentence of Subsection (24) of proposed Rule 62-303.200, Florida Administrative Code, are, for the most part, either approximately five linear miles each (in the case of streams) or approximately five square miles each (in the case of waters not in a defined channel). Subsection (13) of Section 403.031, Florida Statutes, which is referenced in Subsection (25) of proposed Rule 62- 303.200, Florida Administrative Code, provides that "'[w]aters' include, but are not limited to, rivers, lakes, streams, springs, impoundments, wetlands, and all other waters or bodies of water, including fresh, brackish, saline, tidal, surface, or underground waters." The other terms and phrases defined in proposed Rule 62-303.200, Florida Administrative Code, will be discussed, where appropriate, later in this Final Order. Part II: Overview Part II of proposed Rule Chapter 62-303, Florida Administrative Code, contains the following provisions, which describe the "planning list" of potentially impaired waters and how the list will be compiled: Proposed Rules 62-303.300, 62- 303.320, 62-303.330, 62-303.340, 62-303.350, 62-303.351, 62- 303.352, 62-303.353, 62-303.360, 62-303.370, and 62-303.380, Florida Administrative Code. Code Part II: Proposed Rule 62-303.300, Florida Administrative Proposed Rule 62-303.300, Florida Administrative Code, is entitled, "Methodology to Develop the Planning List." It provides as follows: This part establishes a methodology for developing a planning list of waters to be assessed pursuant to subsections 403.067(2) and (3), F.S. A waterbody shall be placed on the planning list if it fails to meet the minimum criteria for surface waters established in Rule 62-302.500, F.A.C.; any of its designated uses, as described in this part; or applicable water quality criteria, as described in this part. It should be noted that water quality criteria are designed to protect either aquatic life use support, which is addressed in sections 62- 303.310-353, or to protect human health, which is addressed in sections 62-303.360- 380. Waters on the list of water segments submitted to EPA in 1998 that do not meet the data sufficiency requirements for the planning list shall nevertheless be included in the state's initial planning list developed pursuant to this rule. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New The second sentence of Subsection (1) of proposed Rule 62-303.300, Florida Administrative Code, incorporates the concept of "independent applicability" by providing that only one of the listed requirements need be met for a water to be placed on the "planning list." At the April 26, 2001, rule adoption hearing, the ERC initially voted to delete from proposed Rule Chapter 62-303, Florida Administrative Code, the language in Subsection (2) of proposed Rule 62-303.300, Florida Administrative Code. The ERC, however, later in the hearing, reversed itself after learning of a letter, dated April 26, 2001, that was sent to the Department by Beverly H. Bannister, the Director of the EPA's Region 4 Water Management Division. Ms. Bannister's letter read, in pertinent part, as follows: EPA expressed significant concern that, under earlier versions of the IWR [Impaired Waters Rule], waters currently identified as impaired on the State's 1998 Section 303(d) list which were determined to have "insufficient data" would be removed from the State's Section 303(d) list and also not appear on the State's planning list with its associated requirement for additional data collection. As a result of EPA concerns, the latest version of the IWR provides that waters on the current 1998 Section 303(d) list that do not meet the data sufficiency requirement of the planning list will be placed on the IWR's planning list, and sufficient data will be collected to verify the water's impairment status. In further discussions with the State regarding the EPA's concern about the 2002 Section 303(d) list, the State has committed to review all waters on the 1998 303(d) list and include all waters that meet the verification requirements of the IWR on the State's 2002 list. In addition, the State will also review all available data from 1989 to 1998 for development of a statewide planning list and include on the 2002 list any additional waters that meet the verification requirements, based on data from 1994 to 1998. (The State is unable to do a complete assessment for data gathered in 1999, 2000, and 2001 because of a national problem in the upload of data into the new Federal STORET data system.) Those waters on the 1998 303(d) list that do not meet the verification requirements will be de-listed for "good cause" and placed on the State's planning list as insufficient to verify the water's use-support status according to the methodology in the IWR. The "good cause" justification for de- listing the waters is based on several factors: 1) the requirements of the State Rule that these waters be moved to a planning list for additional data collection and assessment that will occur within a reasonable period of time; 2) a determination will be made that the waters are either impaired (and placed on the 303(d) list) or attaining its uses; and 3) the State's commitment to EPA that waters on the planning list that appeared on the State's 1998 Section 303(d) list will be monitored and assessed during the first or second rotation through the State's Watershed Management Process consistent with the schedule for TMDL development in EPA's consent decree with Earthjustice. High priority water/pollutant combinations will be monitored and assessed during the first rotation of the watershed cycle (i.e., within 5 years of 2001), and low priority water/pollutant combinations will be monitored and assessed during the second rotation of the watershed cycle (i.e., within 10 years of 2001). After this additional data collection and assessment, the water will be added to the appropriate future 303(d) list if the water is verified to be impaired, or the water will be "de- listed" based on the "good cause" justification that the water is attaining its uses. Waters on the 1998 303(d) list where sufficient data exists to demonstrate the water is meeting the IWR's planning list criteria for use support will be de-listed in the 2002 303(d) list submittal. It is EPA's view that this process will achieve the intent of the CWA and will provide sufficient documentation of the waters still requiring TMDLs by FDEP. Together with the data collection requirements found in Part III of the proposed rule chapter, Subsection (2) of proposed Rule 62-303.300, Florida Administrative Code, ensures that all waters on the Department's 1998 303(d) list (which list is referenced in Subsection (2)(c) of Section 403.067, Florida Statutes) will be assessed by the Department and that they will not be eliminated from consideration for TMDL development simply because there is not enough data to determine whether a TMDL is needed. Part II: Proposed Rule 62-303.310, Florida Administrative Code Proposed Rule 62-303.310, Florida Administrative Code, is entitled, "Evaluation of Aquatic Life Use Support." It provides as follows: A Class I, II, or III water shall be placed on the planning list for assessment of aquatic life use support (propagation and maintenance of a healthy, well-balanced population of fish and wildlife) if, based on sufficient quality and quantity of data, it: exceeds applicable aquatic life-based water quality criteria as outlined in section 62-303.320, does not meet biological assessment thresholds for its water body type as outlined in section 62-303.330, is acutely or chronically toxic as outlined in section 62-303.340, or exceeds nutrient thresholds as outlined in section 62-303.350. Specific Authority 403.061, 403.067, FS. Law Implemented 403.062, 403.067, FS. History -- New This proposed rule, like Subsection (1) of proposed Rule 62-303.300, Florida Administrative Code, incorporates the concept of "independent applicability." A water need meet only one of the four listed benchmarks to be placed on the "planning list for assessment of aquatic life use support." Each of these benchmarks is discussed at greater length in one or more of the subsequent sections of Part II of the proposed rule chapter. Part II: Proposed Rule 62-303.320, Florida Administrative Code Proposed Rule 62-303.320, Florida Administrative Code, addresses the "[e]xceedances of [a]quatic [l]ife-[b]ased [w]ater [q]uality [c]riteria" benchmark described in Subsection (1) of proposed Rule 62-303.310, Florida Administrative Code. It cites Sections 403.061 and 403.067, Florida Statutes, as its "[s]pecific [a]uthority" and Sections 403.062 and 403.067, Florida Statutes, as the "[l]aw[s] [i]mplemented" by the proposed rule. Proposed Rule 62-303.320, Florida Administrative Code, establishes a statistical method (involving "data modeling," as that term is used in Subsection (3)(b)4. of Section 403.067, Florida Statutes) for use in determining whether a water should be placed on the "planning list." It is not feasible, due to limited resources, to examine a water body at every point to determine its true overall condition. Rather, samples must be taken over time and inferences drawn from the sampling results, taking into consideration the "variability [of water quality] occurring in nature" and "that some deviations from water quality standards occur as the result of natural background conditions" (as the Legislature observed in Subsection (11) of Section 403.021, Florida Statutes). The process is, necessarily, characterized by a lack of certainty and the possibility of error. As stated in the NRC Publication: Given the finite monitoring resources, it is obvious that the number of sampling stations included in the state program will ultimately limit the number of water quality measurements that can be made at each station. Thus, in addition to the problem of defining state waters and designing the monitoring network to assess those waters, fundamental statistical issues arise concerning how to interpret limited data from individual sampling stations. Statistical inference procedures must be used on the sample data to test hypotheses about whether the actual condition in the water body meets the criterion. Thus, water quality assessment is a hypothesis-testing procedure. A statistical analysis of sample data for determining whether a water body is meeting a criterion requires the definition of a null hypothesis; for listing a water body, the null hypothesis would be that the water is not impaired. The analysis is prone to the possibility of both Type I error (a false conclusion that an unimpaired water is impaired) and Type II error (a false conclusion that an impaired water is not impaired). . . . The TAC and Department staff had extensive discussions regarding the issue of what particular type of "statistical analysis" to incorporate in the proposed rule chapter before deciding on a binomial distribution analysis. The binomial model is a time-tested nonparametric statistical method that is used where there are two possible outcomes, such as, in the case of water quality sampling, whether a water quality criterion has been exceeded or not. A parametric statistical analysis, based upon an assumption of normal distribution, which, unlike the binomial model incorporated in the proposed rule chapter, takes into account the magnitude of exceedances,36 was considered, but reasonably rejected by the TAC and Department staff because it was anticipated that, in many instances, the number of samples available to the Department would not be adequate to make the underlying distributional assumption with the requisite degree of certainty. The binomial model, which takes sample size into consideration, offers greater certainty with a limited number of samples than does the parametric statistical analysis that the TAC and Department staff rejected. Nonetheless, even in the case of the binomial model, the more samples there are, the more precise the analysis will be. Both Type I errors (false positives) and Type II errors (false negatives) decrease as sample size increases. To ensure greater analytic precision, proposed Rule 62-303.320, Florida Administrative Code, and its counterpart in Part III of the proposed rule chapter (proposed Rule 62-303.420, Florida Administrative Code) contain reasonable minimum sample size requirements (ten, with limited exceptions, for placement on the "planning list," and 20 for placement on the "verified list," which is ten more than the TAC recommended37). The NRC Publication contains the following discussion regarding the appropriateness of employing a binomial model to identify impaired waters needing TMDLs: The committee does not recommend any particular statistical method for analyzing monitoring data and for listing waters. However, one possibility is that the binomial hypothesis test could be required as a minimum and practical first step (Smith et al., 2001). The binomial method is not a significant departure from the current approach--called the raw score approach--in which the listing process treats all sample observations as binary values that either exceed the criterion or do not, and the binomial method has some important advantages. For example, one limitation of the raw score approach is that it does not account for the total number of measurements made. Clearly, 1 out of 6 measurements above the criterion is a weaker case for impairment than is 6 out of 36. The binomial hypothesis test allows one to take sample size into account. By using a statistical procedure, sample sizes can be selected and one can explicitly control and make trade-offs between error rates. (see Smith et al., 2001, and Gibbons, in press, for guidance in managing the risk of false positive and false negative errors). Several states, including Florida and Virginia, are considering or are already using the binomial hypothesis test to list impaired waters. Detailed examples of how to apply the test are beyond the scope of this document, but can be found in Smith et al. (2001) and the proposed Chapter 62-303 of the Florida Administrative Code. In a footnote, the committee added the following: The choice of Type I error rate is based on the assessor's willingness to falsely categorize a water body. It also is the case that, for any sample size, the Type II error rate decreases as the acceptable Type I error rate increases. The willingness to make either kind of mistake will depend on the consequences of the resulting action (more monitoring, costs to do a TMDL plan, costs to implement controls, possible health risk) and who bears the cost (public budget, private parties, etc.). The magnitude and burden of a Type I versus Type II error depend on the statement of the null hypothesis and on the sample size. When choosing a Type I error rate, the assessor may want to explicitly consider these determinants of error rates. The TAC recommended a Type I error rate of five percent (or, stated differently, a confidence level of 95 percent) be used in making listing decisions.38 Department staff responsible for drafting the proposed rule chapter, believing that, as a matter of policy, a 95 percent confidence level was too high and that a higher Type I error rate should be tolerated in order to reduce Type II error, reasonably settled on an 80 percent confidence level for placement on the "planning list" and a 90 percent confidence level for placement on the "verified list." Scientific studies generally do not employ a confidence level below 80 percent. A 50 percent confidence level is "comparable to flipping a coin." Use of the binomial model to determine impairment for purposes of TMDL development (based upon exceedances of water quality criteria) further requires the selection of a fixed "exceedance frequency" representing an acceptable rate of violation beneath which a water segment will not be considered impaired. A permissible "exceedance frequency" accounts for the natural variability of water quality and the uncertainty that the measurements taken are representative of the overall condition of the water segment sampled. The Department, pursuant to EPA guidance, has historically used a ten percent "exceedance frequency" for purposes of identifying, in its 305(b) Report, waters not meeting their designated uses. The TAC and Department staff agreed that a ten percent "exceedance frequency" should likewise be incorporated in the proposed rule chapter. The NRC Publication contains the following discussion regarding "exceedance frequencies" in general and a ten percent "exceedance frequency" in particular: Whether the binomial or the raw score approach is used, there must be a decision on an acceptable frequency of violation for the numeric criterion, which can range from 0 percent of the time to some positive number. Under the current EPA approach, 10 percent of the sample measurements of a given pollutant made at a station may exceed the applicable criterion without having to list the surrounding waterbody. The choice of 10 percent is meant to allow for uncertainty in the decision process. Unfortunately, simply setting an upper bound on the percentage of measurements at a station that may violate a standard provides insufficient information to properly deal with the uncertainty concerning impairment. The choice of acceptable frequency of violation is also supposed to be related to whether the designated use will be compromised, which is clearly dependent on the pollutant and on waterbody characteristics such as flow rate. A determination of 10 percent cannot be expected to apply to all water quality situations. In fact, it is inconsistent with federal water quality criteria for toxics that specify allowable violation frequencies of either one day in three years, four consecutive days in three years, or 30 consecutive days in three years (which are all less than 10 percent). Embedded in the EPA raw score approach is an implication that 10 percent is an acceptable violation rate, which it may not be in certain circumstances. Nonetheless, as the chairman of the committee that produced the NRC Publication, Dr. Kenneth Reckhow, testified at the final hearing in these consolidated cases when asked whether he "believe[d] that a determination of ten percent exceedance [frequency] cannot be expected to apply to all water quality situations": the "notion of one size fits all is . . . a pragmatic approach to the limits of what can be done in a regulatory environment." Dr. Reckhow, during his testimony, declined to "endorse[] as a scientist" the use of an "exceedance frequency" of ten percent (as opposed to some other "particular level"),39 but he stated his opinion (which the undersigned accepts) that "it is important to select a level, and from a science perspective it would be useful to see states employ a level like that or levels roughly around that point and see how effectively they have worked in terms of achieving the goal of meeting designated uses." Subsection (1) of proposed Rule 62-303.320, Florida Administrative Code, sets forth in tabular form, by sample size (from ten samples to 500 samples), the minimum number of exceedances needed for placement on the "planning list." It provides as follows: Water segments shall be placed on the planning list if, using objective and credible data, as defined by the requirements specified in this section, the number of exceedances of an applicable water quality criterion due to pollutant discharges is greater than or equal to the number listed in Table 1 for the given sample size. This table provides the number of exceedances that indicate a minimum of 10% exceedance frequency with a minimum of an 80% confidence level using a binomial distribution. Table 1: Planning List Minimum number of measured exceedances needed to put a water on the Planning list with at least 80% confidence that the actual exceedance rate is greater than or equal to ten percent.

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

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

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

Findings Of Fact The Petitioner is the adjoining neighbor of Harrie E. Smith, the applicant, and runs the Coral Lagoon Resort. This is a commercial establishment which consists of rental units fronting on Bonefish Bay with an interior canal and a series of small boat docking facilities which give each unit docking space and water access. The Petitioner keeps two tame porpoises at the end of this canal which are a tourist attraction. The Petitioner's operation is tourist oriented particularly to those who come to the Keys for fishing or diving excursions. The application to the Department of Environmental Regulation is to the installation of a wooden dock which runs parallel to the Petitioner's northern boundary line. The applicant, Mr. Smith, runs a commercial boat repair facility alongside Mr. Goss' establishment and it is clear there have been misunderstandings between them in the past. The dock has been installed and as noted above, the application to the Department of Environmental Regulation is for an after-the-fact authorization. The department has indicated it intends to grant the permit as it does not see that the dock will degrade water quality or create a condition adverse to the public interest. The petition maintains that the dock will cause water quality problems in that it will encourage the docking of boats which will spill oil, gas and other contaminants into the waters and thereby degrade water quality. It should be noted that the Petitioner maintains extensive docking facilities in his establishment and could be subjected to the same argument.
Findings Of Fact Petitioner John E. Potts applied for a dredge and fill permit pursuant to Chapter 403, Florida Statutes, and Chapter 17-4, Florida Administrative Code. The application calls for an excavated boat slip approximately 32 feet long by 32 feet wide by 7 feet deep. The slip is to be excavated perpendicularly to the Holiday Isle Canal, which is adjacent to and connected with East Pass Lagoon in Destin, Florida. The specific site of the project is Lot 1, Block E, Norriego Road, Holiday Isle, Destin, Florida. Petitioner John H. Savell applied for a dredge and fill permit pursuant to the above authority. His application calls for an excavated boat slip approximately 32 feet long by 44 feet wide by 6 feet deep. This boat slip 15 to be excavated perpendicularly to the Holiday Isle Canal, adjacent to East Pass Lagoon in Destin, Florida. The specific description of this project site is Lot 109, Block F, Gulf Shore Drive, Holiday Isle, Destin, Florida. The Respondent is an agency of the State of Florida having jurisdiction pursuant to Chapter 403, Florida Statutes, and Chapter 17-4, Florida Administrative Code, to require a permit for the construction of stationary installations within waters of the State of Florida. The East Pass Lagoon and the Holiday Isle canals connected with East Pass Lagoon and the two project areas constitute waters of the State over which the Department has dredge and fill permitting jurisdiction pursuant to Rules 47-4.28(2) and 17-4.02(17), Florida Administrative Code. The Petitioners both took the stand in their own behalves and testified generally regarding the dimensions of the proposed boat slips and established that the proposed boat slips would be only used for private craft for docking the same at their homes which are constructed or under construction on the above-described lots. The Petitioners described the method and the equipment to be used for the proposed excavations with particular emphasis on "turbidity curtains" which would be used across the mouths of the subject boat slips as they are being excavated in order to prevent resulting turbidity and siltation from entering waters of the State; to wit, the canal and the lagoon. Additionally, the Petitioners proposed sloping the walls of the boat slips, planting of certain grasses, and possibly even using polyfilter cloth for retention of the soil and newly planted grass on the slopes surrounding the boat slips. The drawing contained in Joint Exhibit 2, however, shows the interior of the boat slips to be vertically bulkheaded with tidal grasses only planted on the shorelines of either side of the mouths of the boat slips. Included along with bulkheads on one side of the boat slips with regard to Mr. Potts' application are two 10-inch pilings for mounting boat davits for lifting a boat out of the water. The Northwest District Office of the Department of Environmental Regulation accepted the permit applications submitted by the Petitioners, and the file and the applications were assigned to Mr. Cliff Rohlke of the District staff. Mr. Rohlke is employed as an Environmental Specialist, serving as a dredge and fill inspector. He was accepted as an expert witness in the area of water quality, with specific emphasis on dredge and fill permitting problems as they relate to water quality, as well as aquatic vegetation and its characteristics and functions in relation to water quality. Mr. Rohlke was familiar with the Holiday Isle Canal system and the adjoining and involved development. He and another Department witness, Mr. Mark Snowdon, had done previous on-site inspections and studies of the subject area. In October, 1980, Mr. Rohlke and Mr. Snowdon performed a study designed to determine water quality in the subject canals in the Holiday Isle development. Their studies in October, 1980, showed only one water quality violation in the canal system. Similar studies performed on July 21, 1981, by Mr. Rohlke and Mr. Snowdon, however, showed dissolved oxygen violations in five of the six sampling stations used to perform the study within the canals. Even the one station not shown to actually violate water quality standards in terms of dissolved oxygen had significantly lower levels of dissolved oxygen than a comparable location in the 1980 study (see Respondent's Exhibit 6). Studies were performed again on August 26, 1981, by the same two witnesses. These studies also showed dissolved oxygen standard violations in the canals. The presence of dissolved oxygen content in the water which was below standards enunciated in Chapter 17-4, Florida Administrative Code, was borne out by the presence of an algae bloom in the canal observed by Mr. Rohlke. Mr. Rohlke established that the procedures used to take the samples in the case of each study, on each date, were scientifically correct, and the samples taken were correctly obtained and preserved. The instruments used to collect and measure the samples were the best available and were properly and recently calibrated, as established by Mr. Snowdon's testimony. During the time parameters of these studies, between October, 1980, and August, 1981, many boat slips similar to those proposed in these proceedings were excavated along the banks or perimeters of the Holiday Isle canals in the Holiday Isle development. The increased number of boat slips was shown to directly relate to the decreasing water quality, as measured by the decreasing dissolved oxygen content in the canal water. Boat slips dredged and excavated at a 90 degree angle to the water body itself tend to impede the normal flushing activity of the tides and other water movement. The decreasing, or poor, water quality in the canals, established to be a fact by this witness, was thereby aggravated by the increasing number of boat slips excavated during the years in question. Boat slips, especially those constructed 90 degrees to the water body to which they adjoin, tend to catch and hold surface debris, including oil slicks, which either falls into the boat slips or is moved into them by wind or water currents. The tendency to hold all types of surface debris tends to contribute to poor water quality in the boat slips, as well as in the adjacent canals. Mr. Rohlke established that the construction of the boat slips would have a short-term additional detrimental effect of increasing turbidity or siltation in the canals, although the Petitioners' proposal to construct turbidity curtains across the mouths of the boat slips while they are being excavated would eliminate to a large extent this threat to water quality. An ever-increasing amount of aquatic vegetation occurring on or near the banks of the canal system has been removed or otherwise destroyed during the years in which witness Rohlke has observed and studied the water quality in the canal, with a concomitant, cumulative degrading effect on water quality in the canal system. No such aquatic vegetation remains at the vicinity of Petitioner Potts' proposed boat slip. Construction of Petitioner Savell's boat slip will eliminate an additional area of aquatic vegetation which currently is in place and is currently contributing to the maintenance of water quality by filtering, assimilating, transforming and rendering harmless nutrients and other pollutants. The construction of these and the previous boat slips was shown to definitely eliminate shallow water habitat essential to a variety of benthic algae and other organisms and microscopic organisms which constitute crucial initial links in the aquatic "food chain" of the involved waters of the State and which are important to the survival and reproduction of multiple forms of marine life including commercially and recreationally important fish species. Although the Petitioners propose to plant grass on the sides on the boat slips and to slope the banks of the boat slips instead of constructing them in a perpendicular fashion, the proposed grassed and angled sides were not shown to be effective in stabilizing the slopes of the boat slips in order to prevent additional turbidity and degradation of water quality. Both the angle of the slopes and other factors, such as boat wakes or other sources of wave action, will tend to cause the newly planted grass and soils to slough off into the boat slips and thus into State waters, even if extraordinary methods of retention such as porous polyfilter cloth is used on the slopes. The several studies of water quality in the canal systems since October, 1980, clearly establish that a cumulative impact in the direction of continuing further degradation of water quality in the canal system and in the lagoon has resulted from the proliferation of excavated boat slips in the Holiday Isle Canal. The construction of any additional such boat slips will further accelerate the decline in water quality caused in part by previously constructed installations of this type. These permits and the resulting boat slips were not shown to be required in order for the Petitioners to have mooring spaces for their boats on their property. The Petitioners are entitled to construct a private dock of up to 500 square feet without a Department permit and further Witness Potts, at least, even though he proposes to build a boat slip, apparently intends to construct davits within the boat slip "for lifting his boat out of the water after it is parked there. It was not shown by either Petitioner why the use of davits for lifting the boat out of the water along and on the existing canal bank or a private dock on the front of the property, or a combination of the two, would not adequately provide mooring space and protection for their boats without the necessity for the excavation of the subject boat slips. In summary, aside from their own testimony regarding their opinion that the boat slips would not further degrade the waters in the canal or lagoon, the Petitioners presented no scientific studies, plans or test results which could establish that the proposed dredging and filling operations would not cause temporary or permanent violations of appropriate water quality standards.
Recommendation Having considered the foregoing findings of fact and conclusions of law, the evidence in the record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is, therefore RECOMMENDED: That the Department of Environmental Regulation enter a final order denying the requested dredge and fill permits.

SAVELL, DOAH Case No. 81-2708 and JOHN E. POTTS, DOAH Case No. 81-2710 Petitioners, vs. OGC Case No. 82-0343 STATE OF FLORIDA, DEPARTMENT OF ENVIRONMENTAL REGULATION, Respondent. /
The Issue The issues are whether Georgia-Pacific Corporation is entitled to the issuance of an industrial wastewater facility permit under the National Pollutant Discharge Elimination System program that would authorize it to discharge industrial wastewater to the St. Johns River in Putnam County, Florida, and whether Georgia-Pacific Corporation has met the statutory criteria for a related administrative order for the interim discharge to Rice Creek in Putnam County, Florida.
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: The Parties Respondent, Department of Environmental Protection (Department), is the state agency authorized under Chapter 403, Florida Statutes, to regulate discharges of wastes to waters of the State. Under approval from the United States Environmental Protection Agency (EPA), the Department administers the National Pollutant Discharge Elimination System (NPDES) permitting program in the State. The Department also enforces specific water quality standards that have to be achieved in order to ensure protection of the designated uses of surface waters in the State. Respondent, Georgia-Pacific Corporation (Georgia- Pacific), owns and operates a bleached and unbleached kraft pulp and paper mill in Putnam County, Florida. The plant presently discharges treated wastewater to Rice Creek, a Class III water of the State, and a tributary of the St. Johns River. Petitioner, Putnam County Environmental Council, Inc. (PCEC), alleged in the Petition for Formal Administrative Hearing (Petition) that it is a non-profit Florida corporation headquartered in Palatka, Florida. However, other than a statement by one witness that PCEC was incorporated on an undisclosed date prior to the hearing, PCEC failed to present any evidence to establish its corporate status or residency in the State of Florida. According to the same witness, the organization was created in an unincorporated status in 1991, and it currently has 65 members who use and enjoy the St. Johns River for recreational purposes. Petitioner, Stewards of the St. Johns River, Inc. (SSJR), also alleged in the Petition that it is a non-profit Florida corporation with headquarters in Jacksonville, Florida. Like PCEC, SSJR failed to prove its corporate status or residency in the State of Florida. Although the number of members in SSJR is unknown, "many" of its members are boaters and "most" live along the St. Johns River. Petitioner, Linda Young, is Southeast Regional Coordinator for the Clean Water Network and a citizen of the State of Florida. As such, she has standing to "intervene" in this action under Section 403.412(5), Florida Statutes. In this complex case, the parties have presented extensive and conflicting evidence regarding the factual issues raised by the pleadings. In resolving the numerous conflicts in that testimony, the undersigned has accepted the more credible and persuasive evidence, as set forth in the findings below. The Applicant's Mill Operation Georgia-Pacific's Palatka mill was built in the 1940's before the establishment of Department water quality standards and classifications. Because of the nature of the pulping process, the mill has not been able to fully meet water quality standards in Rice Creek because of poor dilution. Georgia-Pacific receives wood chips from a sister facility and purchases residual chips from local wood products facilities. Those chips are separated into pine and hardwood, conveyed into the pulp processing facility, and loaded into digesters, that is, industrial-sized pressure cookers, which cook the chips for several hours. Pulp from the digesters goes to the brown kraft, bleached kraft, and tissue manufacturing facilities. Water in the manufacturing process is used, re-used, and recirculated until it cannot be used again, at which point it is conveyed into a primary wastewater clarifier, which is used to settle out fiber and other settleable solids. Additional wastewater sources are collected in sumps located in the facility, which are discharged into the primary clarifier. The underflow from the primary clarifier flows into a solids settling area (sludge pond) while the water from the primary clarifier passes into a secondary treatment system. The secondary treatment system uses aerobic and facultative biological treatment. Stormwater at the facility also flows into the treatment system. The secondary treatment system consists of four ponds in series: Pond 1, 485 acres, aerated with over 1600 horsepower of aeration; Pond 2, 175 acres, with 140 horsepower of aeration; Pond 3, 130 acres, with 120 horsepower of aeration; and Pond 4, 100 acres. Pond 4 is a quiescent basin, used to settle solids in the wastewater before discharge. The treatment system has a very long hydraulic detention time; once water enters the system, it remains there for 50 to 60 days. After treatment, a side stream of roughly 8,000,000 gallons per day of treated effluent is withdrawn, oxygenated with liquid oxygen, and discharged at two locations in Rice Creek: 3.4 miles upstream from the St. Johns River (Outfall D-001); and 2.4 miles upstream from the St. Johns River (Outfall D-002). Under low flow conditions, effluent from the Georgia-Pacific mill dominates the flow in Rice Creek. The Application Process Rice Creek is a small tributary of the St. Johns River, particularly in its upper reaches where Georgia- Pacific's effluent discharge occurs. Over the years, there have been exceedances of certain Class III water quality standards including specific conductance, color, and periodically whole effluent toxicity. Because of this, and during the permit review process, the Department began considering alternatives for mitigating or eliminating those existing concerns with the facility's discharge. In October 1992, Georgia-Pacific applied to the Department for the renewal of its existing wastewater discharge permit. In June 1994, Georgia-Pacific submitted an application to the Department for the construction and operation of an industrial wastewater treatment and disposal system. This application included a request to relocate Georgia-Pacific’s existing discharge to the St. Johns River. Because Georgia-Pacific submitted timely permit applications, it is authorized to continue operations based on an "administratively extended permit." In June 1994, Georgia-Pacific also applied to the EPA for a permit under the NPDES program. In October 1994, the EPA acknowledged receipt of a timely application for the renewal of Georgia-Pacific's existing NPDES permit, advising Georgia-Pacific by letter that its permit was automatically extended and that continued operation was authorized in accordance with the existing permit and 5 U.S.C. Section 558(c). On May 24, 1995, the Department advised Georgia- Pacific that the EPA had granted the Department the authority to administer the NPDES program and that its state permit and existing NPDES permit were deemed combined into one order. In response to a Department request, in November 1995, Georgia-Pacific submitted to the Department an antidegradation review for the relocation of its discharge. After Georgia-Pacific applied to the Department for a renewal of its NPDES permit, the Department directed Georgia-Pacific to provide alternatives that would ensure compliance with water quality standards. Georgia-Pacific submitted a proposal to construct a pipeline that would enable it to discharge its effluent to the middle of the St. Johns River. Under that proposal, Georgia-Pacific would achieve compliance with water quality standards as a result of greater dilution in the St. Johns River. Based on a review of Georgia-Pacific's submittal, the Department determined that Georgia-Pacific could in fact achieve water quality standards by constructing a pipeline to the St. Johns River. Likewise, the EPA concluded that Georgia-Pacific could receive a permit to discharge to the St. Johns River through a pipeline, without additional process improvements. Although the Department concluded that compliance could be achieved solely by the construction of a pipeline, it began discussions with Georgia-Pacific and EPA in order to examine other approaches that might lead to compliance in Rice Creek. These discussions culminated in a decision that Georgia-Pacific would invest substantial funds in the installation of additional technology and also be assured of some ultimate means to achieve compliance with water quality standards. On May 1, 2001, the Department issued a Notice of Intent to Issue an industrial wastewater permit, together with an Order Establishing Compliance Schedules Under 403.088(2)(f), Florida Statutes (the Administrative Order). In late January 2002, Georgia-Pacific submitted a request to the Department asking for consideration of two changes to the proposed permit: first, a request to relocate a groundwater monitoring well; and second, a request to review the Department's proposed mixing zone in the St. Johns River for the transparency standard. The Department also proposes a minor change in permit conditions to allow approval of the bleach plant monitoring plan to take place within sixty days after the issuance of the final permit. Both of Georgia- Pacific's requests were reviewed by the Department, and it has recommended that they be included in the proposed permit. Technology-Based Effluent Limits and Water Quality- Based Effluent Limits When considering a permit application such as the one here, the Department reviews the application to determine compliance with technology-based effluent limits (TBELs) and water quality-based effluent limits (WQBELs). TBELs are minimum industry standards that all facilities must meet regardless of their discharge location. They are predominantly production-based, and they limit the mass of pollutants that may be discharged based on the mass of product produced. Those limits generally reflect EPA's assessment of the industry standard regarding what can be met in a given discharge. In the preparation of a permit, the Department practice is to first determine the TBELs that would apply. In contrast, a WQBEL reflects how low the discharge must be (or how effective treatment must be) for a given parameter to meet water quality standards. Relief mechanisms such as mixing zones are inherent in WQBELs. A WQBEL is necessary only for those parameters for which there is a reasonable potential for the facility either to exceed the water quality standard or come close to exceeding the standard. As a matter of agency practice, the Department does not impose a limit unless there is a reasonable potential to exceed a standard. In order to determine whether there is such a reasonable potential for exceeding a standard, the Department will review past operations and other information it may have regarding the characteristics of the discharge. For a discharge such as the one proposed in the present case, a "Level II" WQBEL is required. The Department's Point Source Section, with expertise in the field of water quality modeling, analyzes the Level II WQBEL. Georgia-Pacific must meet certain technology-based standards, such as those set forth in the Cluster Rule. The Cluster Rule has been promulgated by the EPA and adopted by the Department and requires the installation of technologies to eliminate the use of elemental chlorine in the bleaching process. The Palatka facility far exceeds (performs better than) technology-based effluent limits. In March 1998, the Department created a document titled "Level II Water Quality Based Effluent Limitations for the Georgia Pacific Corp. Palatka Mill" (the WQBEL Technical Report]. The WQBEL Technical Report has a typed notation on the title page reading "March 1998 -- Final." The WQBEL Technical Report contained the following effluent discharge limitations: The following are the effluent limitations for the Georgia-Pacific Palatka mill discharge to the St. Johns River based upon results from the Level II WQBEL. Review comments from EPA Region 4 are included in the correspondence section. Parameter Limitation Discharge 60 MGD Daily Maximum BOD5 Summer (June 1 - November 30) 3,500 lbs/day maximum thirty day average Winter (December 1 – May 31) 7,170 lbs/day maximum thirty day average TSS Summer (June 1 - November 30) 5,000 lbs/day maximum thirty day average Winter (December 1 – May 31) 10,000 lbs/day maximum thirty day average Dissolved Oxygen 2.7 mg/l minimum Specific conductance 3,220 umhos/cm daily maximum Un-Ionized Ammonia Nitrogen Summer (June 1 - November 30) .11 ug/l daily maximum Winter (December 1 – May 31) .13 ug/l daily maximum Iron (Total Recoverable) 2.91 mg/l daily maximum Cadmium (Total Recoverable) 3.46 ug/l daily maximum Lead (Total Recoverable) 5.87 ug/l daily maximum Zinc (Total Recoverable) 480 ug/l daily maximum When the WQBEL Technical Report was approved in 1998, the Department's Northeast District Office did not prepare a separate formal notice of approval. The WQBEL Technical Report was transmitted by memorandum from the Water Quality Assessment Section to the Department's Director of District Management for the Northeast District on April 13, 1998, where it remained on file. The WQBEL Technical Report complied with the plan of study previously approved by the Department, and it met the requirements of Rule 62-650.500, Florida Administrative Code. Both the Department and EPA staff concurred with the approval of the WQBEL Technical Report. They agreed that the construction of a pipeline and the relocation of the discharge to the St. Johns River would yield a net environmental benefit without additional process improvements. Upgrades Implemented and Required in the Proposed Agency Actions As described more fully below, Georgia-Pacific has modified its production and treatment processes in such a manner as to improve its overall environmental performance. In installing some of those modifications, Georgia-Pacific undertook what was required by federal and state law. For others, Georgia-Pacific has exceeded what it was required to do under state or federal law. To comply with the Cluster Rule, Georgia-Pacific eliminated two bleach plants and installed a new bleach plant, one which uses chlorine dioxide as opposed to elemental chlorine. The implementation of this technology is primarily aimed at eliminating the mechanism for the formation of dioxin in the bleaching plant. Compliance with the Cluster Rule generally requires, among other things, conversion to an elemental chlorine-free bleaching system. Georgia-Pacific is in compliance with the Cluster Rule. Under the Cluster Rule, Georgia-Pacific is required to sample for dioxin at its bleach plant, with a limit of under 10 picograms per liter. Georgia-Pacific has experienced reductions in the color of its effluent as the result of the chlorine dioxide conversion as well as reductions in specific conductance. The reductions in specific conductance are particularly significant because Georgia-Pacific has decreased its effluent flow, which would ordinarily increase specific conductance in the absence of additional improvements. After conversion to chlorine dioxide, Georgia- Pacific began monitoring for parameters defined by the Cluster Rule. In that monitoring, Georgia-Pacific has tested "non- detect" for dioxin and chlorinated phenolics. Specifically, Georgia-Pacific has monitored dioxin in its effluent, as well as within its process –- before dilution with other wastewater –- and the monitoring results at both locations are likewise "non-detect" for dioxin. Furthermore, levels of chloroform and adsorbable organic halides (AOX) have been well within the limits imposed by the proposed permit and the Cluster Rule. Georgia-Pacific has voluntarily agreed to install by April 15, 2006, an oxygen delignification system, or a like system that produces similar or better environmental benefits. Oxygen delignification is a precursor to bleaching, which removes lignins from the fiber before the product is bleached. This process is significant because lignin consumes chemicals, impedes bleaching, and prohibits achieving brightness targets in the bleach plant. The cost associated with the oxygen delignification system is $22,700,000. This commitment is reflected in the proposed Administrative Order and Permit. Oxygen delignification has been identified as having significant benefits in terms of reducing the color and specific conductance of effluent. Georgia-Pacific voluntarily agreed to install by August 15, 2003, a new brownstock washing system to replace four existing brownstock washing lines. A brownstock washer is a piece of equipment that washes organics away from fiber, after pulping and before oxygen delignification. The cost of this equipment is approximately $30,000,000. This commitment is reflected in the Administrative Order and Permit. The new brownstock washers are not required by Department rules, but they will be helpful in reducing the specific conductance of effluent. Georgia-Pacific has also voluntarily agreed to install a green liquor dregs filter. This system would remove dregs from the effluent system and reduce specific conductance and color in the effluent. The cost of the green liquor dregs filter is $1,100,000. This commitment is reflected in the Administrative Order and Permit. Under the proposed agency action, Georgia-Pacific is likewise required to install additional equipment for the implementation of its best management practices program to minimize leaks and spills in the process sewer. This equipment, including controls on the brownstock washer system, and the installation of a spill control system, pumps, and piping, has been installed at a cost of $7,100,000. Georgia-Pacific has also optimized the performance of its treatment system through the relocation of its aerators in the treatment ponds and modifying its nutrient feed system. This has led to reduced levels of biological oxygen demand (BOD) in the discharge, as well as improved treatment for total suspended solids. In addition, Georgia-Pacific has voluntarily installed a reverse osmosis system to recycle certain internal streams, which in turn has led to reductions in specific conductance, at a cost of $3,300,000. To comply with the proposed agency actions, Georgia- Pacific expects to expend a total of approximately $170,000,000 for upgrades for the purpose of producing environmental benefits. Additional money is earmarked for other environmental performance issues, such as water conservation. Except for technology-based limits adopted by rule, the Department does not dictate how a facility achieves compliance with water quality standards. Georgia-Pacific demonstrated that its environmental performance is substantially better than required by technology-based limits. Based on the foregoing, it is reasonable to find that Georgia-Pacific’s commitments to process improvements will lead to a general improvement in water quality in the receiving waters. Relocation of the Discharge As noted above, because of the minimal dilution available in Rice Creek, Georgia-Pacific has never been fully able to achieve water quality standards in Rice Creek, a Class III water body. Rice Creek continues to exceed water quality criteria for specific conductance and color; historically, the discharge had experienced exceedences for the chronic toxicity criterion. Under present conditions, with Georgia-Pacific discharging to Rice Creek and Rice Creek flowing to the St. Johns River, elevated levels of color are experienced along the shoreline of the St. Johns River in the area of existing grass beds. Modeling shows that under current flow conditions from Rice Creek, those color effects are observed on the northwest bank near the confluence of Rice Creek with the St. Johns River. If the discharge is relocated to the St. Johns River and discharged near the river bottom through a diffuser, it will beneficially change the distribution of color impacts both to Rice Creek and the St. Johns River. Color in Rice Creek will improve, returning to its background color of 100 to 150 platinum cobalt units (pcu). Specific conductance within Rice Creek will also be markedly reduced. Because the input will occur in the middle of the St. Johns River, with higher flows and greater turbulence, there will no longer be relatively highly colored water flowing along the shoreline. Therefore, the relocation will provide a significant benefit of moving highly colored water away from grass beds and will mitigate against any existing effects on those grass beds. It is beneficial to relocate discharges to the middle of a stream, as opposed to the edge of a shoreline, where effluent tends to hug the shoreline. Therefore, regardless of the process improvements, there will be a net environmental improvement by relocating the discharge to the middle of the St. Johns River The discharge from the proposed diffuser will be comparatively benign, in comparison to the present flow from Rice Creek into the St. Johns River. This is because the effluent would not reach or hug the shoreline in such a scenario but rather would be diluted in rising to the surface, as well as by its lateral movement in the direction toward the river bank. The relocation of the discharge to the middle of the St. Johns River will cause improvements through localized changes in concentrations near the diffuser and the confluence of Rice Creek and the St. Johns River. Based on the foregoing, it is found that Georgia- Pacific’s proposed discharge into the St. Johns River will not result in water quality degradation, but will instead lead to a general improvement in water quality. Proposed Conditions in the Permit and Administrative Order Before certifying completion of the required manufacturing process improvements, Georgia-Pacific is required to submit to the Department a report on its ability to optimize the modifications, as well as a separate report which would determine whether Georgia-Pacific can meet certain limits that would enable a continuing discharge to Rice Creek. If the water quality improvements are sufficient to achieve standards in Rice Creek, the permit would be reopened and Georgia-Pacific would be required to maintain the present discharge location to Rice Creek. Otherwise, Georgia-Pacific would be authorized to construct the pipeline to the St. Johns River. The permit is drafted so that Georgia-Pacific will verify the need for mixing zones, as well as the dimensions of proposed mixing zones, after process improvements are complete. The Administrative Order imposes interim effluent limitations during the compliance period described in that Order. The Administrative Order contains "report-only" conditions for certain parameters. For those parameters which do not have interim limits, there is no appropriate standard to apply because information on effluent and water quality conditions is incomplete. The Department also found it unreasonable to impose interim limits that will be met only after Georgia-Pacific completes the improvements requested by the Department. Under Department practice, it is reasonable to impose "report only" conditions for parameters when it is unclear whether the discharge for the facility presents a concern for potential exceedences of water quality standards. In addition, "report only" conditions are used when a facility is undertaking an effort to address problems for certain parameters during a period necessary to achieve compliance. The proposed permit includes mixing zones in the St. Johns River for dissolved oxygen, total recoverable iron, total recoverable cadmium, total recoverable lead, un-ionized ammonia, turbidity, and specific conductance. The length of each of those mixing zones is 16.5 meters, that is, limited to the rise of plume. A mixing zone is also required for transparency, which will require a length of 734 meters. Within 12 months after certifying completion of the manufacturing process improvements, Georgia-Pacific will be required to re-evaluate the need for mixing zones and effluent limits and re-open the permit as necessary to include final mixing zones, effluent limits, and monitoring requirements. Compliance with Ambient Water Quality Standards The Petition contends that Georgia-Pacific has not provided reasonable assurances that it would comply with the following standards: nutrients (paragraph 18); dissolved oxygen (paragraph 20); chronic toxicity (paragraph 21); total suspended solids (paragraph 23); iron (paragraph 25); and phenolic compounds (paragraph 26). Although no water quality standard is directly applicable, Petitioners also addressed the following water quality issues: biological oxygen demand (BOD) (paragraph 20); dioxin, "related compounds," chlorinated organics, AOX, and chemical oxygen demand (COD) (paragraph 22); color (paragraph 24); and total suspended solids (TSS), which is alleged to include total organic carbon (TOC) (paragraph 94). Petitioners asserted that dioxin, chlorinated organics, TSS, and AOX are significant in considering compliance with the "free-from" standard in Rules 62- 302.500(1) and 62-302.530. In determining whether water quality standards will be met, those allegations should only be considered in reference to those adopted standards for the "free-from" standard. The effluent data establishes that Georgia-Pacific will consistently meet the proposed permit limits for discharge to Rice Creek. Georgia-Pacific's treatment facility has the capacity to comply with the proposed permit limits for discharge to Rice Creek, and there is a very high degree of assurance that it has the capability to comply with those standards in the future. In addition, Georgia-Pacific's treatment facility is able to meet the WQBELs established for discharge into the St. Johns River. Evaluation and modeling demonstrate that if a discharge to the St. Johns River is undertaken, the St. Johns River will meet Class III water standards at the edge of the mixing zone if Georgia-Pacific complies with its proposed effluent limits. Also, the effluent will meet all applicable effluent guidelines and technology-based standards adopted in the Florida Administrative Code. The effluent will not settle, form deposits, or create a nuisance, and it will not float as debris, scum, or oil. Finally, the effluent will not produce color, odor, taste, or other conditions so as to create a nuisance. Georgia-Pacific performed an analysis to determine the effluent limits that would be necessary to achieve water quality standards. This analysis included water quality modeling, which is a method of summing up inputs and losses, calculating the amount of material in a system, and determining the concentration of a substance. The model was used to geometrically represent the St. Johns River, Etonia Creek, and the reach of the St. Johns River within the study area, which extended from Buffalo Bluff (15 miles upstream of the confluence of Rice Creek and the St. Johns River) to Mile Point 50. Rice Creek enters the St. Johns River at Mile Point 74. When a model is performed, the model will yield estimates or predictions of concentrations throughout a water body. Those predictions can be compared to field observations and measurements; if the model is done properly, the calculated numbers should agree with the measured numbers. Modeling is used to evaluate future conditions based on hypothetical future changes to the system. The modeling methods and advanced time-variable models employed by Georgia- Pacific's consultants were approved by the Department. Georgia-Pacific prepared a plan of study to obtain field data in the St. Johns River for the purpose of assuring that the models would simulate observed concentrations of constituents. The Department approved that plan of study and published a notice of approval. The Department also approved the quality assurance project plan for the collection of water quality data in Georgia-Pacific's modeling efforts. After approval of the plan of study and quality assurance project plan, Georgia-Pacific's consultants performed water quality surveys in November 1994 and May 1995. The models employed by Georgia-Pacific's consultants were calibrated and produced the observed water quality results. The proposed diffuser would be located about one foot from the bottom of the channel. As designed, the plume would leave the proposed diffuser and spread out, with the upper part of the plume going to the surface of the water. The plume model calculates the dilution at the centerline of the plume, where there would be a minimum of dilution. This method of using the centerline as a reference point leads to a conservative analysis, and it would require the Applicant to achieve more dilution than might otherwise be necessary to achieve water quality standards. For regulatory purposes, the Department usually uses the maximum height of the rise of the plume to determine a mixing zone, the point at which concentrations along the centerline of the plume would level off. Because of that practice, for certain parameters where the required mixing zone is less than the distance of the rise of the plume, a decrease in effluent limits would not lead to a decrease in the size of the mixing zone. Tidal actions will cause re-entrainment, that is, the movement of dissolved substances back into the plume area. This factor reduces the dilution factor that otherwise would apply to the system. This factor is accounted for in modeling by tying in a diffuser computation to a water quality model. The modeling employed by Georgia-Pacific assumes 7Q10 conditions, that is, a conservative assumption that flow is equal to the lowest one-week average for a ten-year period, where there is little dilution. The employment of this conservative method would minimize the probability of exceedences in the receiving water body. The projection employed by Georgia-Pacific's consultants was even more conservative because the 7Q10 flow rate is assumed to apply through a 60-day average flow, a condition that may never occur, and would not be expected to occur once in ten years. In contrast, the use of time-variable simulations would lead to less stringent permitting requirements. The permit provides reasonable assurance that the construction, modification, or operation of the treatment system will not discharge or cause pollution in violation of Department standards. The permit provides reasonable assurance that, based on the effluent limitations determined by the Department in the WQBEL Technical Report, water quality standards would be met outside the area of the proposed mixing zone for specific conductance, dissolved oxygen, un-ionized ammonia, iron, cadmium, lead, and zinc. Based on additional analysis as reflected in Georgia-Pacific's proposed amendment to the draft permit, Georgia-Pacific would achieve compliance with the transparency standard with the mixing zone described in its proposed amendment, that is, with a total length of 734 meters. The chronic toxicity criterion is a biological measurement which determines whether organisms are impaired by effluent. If impairment is demonstrated, the test does not indicate what component of the effluent is causing the effect. Georgia-Pacific is required to conduct testing for acute and chronic toxicity twice a year. Current tests undertaken in May and October 2001 are representative of effluent conditions after Georgia-Pacific undertook conversion of the bleach plant to chlorine dioxide. Those tests demonstrate that Georgia-Pacific is in compliance with the acute and chronic toxicity criterion since the conversion to chlorine dioxide bleaching. Georgia-Pacific is also in compliance with the biological integrity standard, based on the most recent fifth-year inspection. Because of the flow characteristics and the characteristics of pulp mill effluent, the pollutants associated with the effluent are not assimilated as the effluent travels from the point of discharge, through Rice Creek, to the St. Johns River. The particulates associated with pulp mill effluent are so small or fine that they will remain in suspension and thus not settle out in Rice Creek. In addition, because Rice Creek is channelized, there is no sloping side that would enable the growth of vegetation that would filter the water. Furthermore, even if there was a sedimentation process occurring in Rice Creek, no additional sedimentation would occur after the system reaches an equilibrium point. Although Rice Creek does cause a small decrease in BOD through oxidation, Georgia-Pacific has compensated for that factor by the injection of oxygen in the effluent. Thus, the direct piping of effluent to the St. Johns River (as opposed to a discharge into Rice Creek, which flows into the St. Johns River) would not result in any significant increase in pollutant loading to the St. Johns River. In addition, the construction of a pipeline would take place only after additional technologies have been implemented to maximize pollutant reduction. Compliance with the Reasonable Assurance Standard Georgia-Pacific has provided reasonable assurances for the proposed permit to be issued for a discharge into the St. Johns River. This finding is based upon Georgia-Pacific's ability to meet the effluent standards described in the draft permit, and modeling results demonstrating that, with the proposed mixing zones for certain parameters, a discharge into St. Johns River, as designed, will not result in a violation of Class III standards. Mixing Zones In Section H of their Petition, Petitioners challenged the proposed mixing zones set forth in the proposed Permit. Petitioners generally alleged that the proposed mixing zones were "enormous" and that they failed to comply with certain rules restricting mixing zones. In their Petition, Petitioners articulated three theories to support the proposition that the mixing zones were illegal: first, that the mixing zones would include a nursery area of indigenous aquatic life, including beds of aquatic plants of the type listed in Rule 63-302.200(16); second, that the mixing zone, by itself, would lead to a violation of the minimum criteria in Rule 62-302.500; and third, that the mixing zones, or a combination of those mixing zones, would result in a significant impairment of Class III uses in the St. Johns River. Petitioners were authorized to amend their Petition to add additional allegations to paragraphs 17 and 67 of their original Petition regarding the mixing zone. Under those amendments, Petitioners alleged that Georgia-Pacific’s proposed amendment to the draft permit would (a) improperly expand the mixing zone; (b) fail to account for the length of the diffuser; (c) improperly substitute "transparency" for "color"; and (d) prevent isolation of transparency impacts from color in the discharge. However, there is no evidence which ties those allegations to any regulatory standard that would affect the proposed agency action. Petitioners also contended that color was a surrogate for chemical oxygen demand, as well as for substances that are alleged to cause chronic or acute toxicity. However, as shown by the testimony of Department witness Maher, the permit condition for "color" was a surrogate only for the transparency standard. No evidence to support a contrary inference was presented. Petitioners also made general allegations that the proposed mixing zones are illegal, without a clear indication of what is deemed illegal about the mixing zones. Although the Petition includes a general argument in opposition to mixing zones, Petitioners were unable to suggest a legal basis for alleging that the mixing zones were illegal. For example, Petitioners alleged that certain mixing zones are enormous but failed to articulate why they are so enormous as to be illegal. They did not allege that the Department had erred by allowing a larger mixing zone than Georgia-Pacific should have received under applicable rules. Indeed, such a position would be antithetical to Petitioners' allegations that Georgia-Pacific had failed to achieve water quality standards for a number of parameters. The accepted testimony establishes that Georgia-Pacific's proposed mixing zones will comply with Department rules. No persuasive evidence was presented to the contrary. Because the effluent quality will differ from present conditions after completion of the process improvements, the proposed mixing zones will not be final until after process improvements have been made, the operation has been stabilized, and the mixing zones have been re- verified. No mixing zones are authorized in the Administrative Order. The Administrative Order contains a table setting forth potential mixing zones that are used as a benchmark to determine whether Georgia-Pacific can meet water quality standards in Rice Creek. The table sets out a series of hypothetical mixing zones at 800 meters, that is, the maximum presumptive distance afforded without additional relief mechanisms. Because no mixing zones are proposed to take effect in Rice Creek, there can be no issue of "illegal" mixing zones in Rice Creek. Within a range of potential discharge flows, from 20 MGD to 60 MGD, water quality standards will be met within the area of the proposed mixing zones for all parameters for which mixing zones are required. Mixing zones are allowed by Department rules and are considered a part of Florida water quality standards. In the context of the Department's permitting review, if a modeling analysis shows that the concentration of a pollutant in effluent is greater than the water quality criterion, the Department will determine if the amount of dilution in the receiving water is sufficient to assimilate the pollutants of concern. The Department will then determine either the length (in the case of a river) or area (in the case of an estuary) of a water body that would be necessary to achieve compliance through dilution. Based on chloride levels, the St. Johns River at the area of concern would not be considered an estuary under Department rules. Each of the proposed mixing zones would be less than 800 meters in length (as allowed by Department rule) and less than 125,600 square meters in area (a limitation that would apply only if the area was an estuary). The proposed discharge will comply with all minimum rule requirements with respect to mixing zones, such as those for dissolved oxygen, turbidity, and the absence of acute toxicity. Likewise, the proposed mixing zones will not impact any nursery areas for indigenous aquatic life. Nutrient Issues In Section I, Petitioners contested the Department's decision to not require effluent limits to prevent a violation of the narrative water quality criterion for nutrients. For reasons addressed in the undersigned's Order dated February 14, 2002, that issue is waived based because of Petitioners' failure to file a timely challenge to the WQBEL Technical Report. In addition, based on the findings set out below, Georgia-Pacific has provided reasonable assurances that it will not violate the narrative standard for nutrients. Further, the evidence shows that effluent limits for nutrients are not presently warranted. Petitioners presented testimony that the St. Johns River may be nitrogen-limited or phosphorous-limited at different times of the year, which means that concentrations of one or the other would limit algae growth at different times of the year. Relative light levels, as well as the penetration of light, also affect algae growth. Georgia-Pacific’s treatment system requires the addition of ammonia because ammonia or nitrate is a necessary nutrient for the growth of bacteria in the treatment system. Ammonia and nitrate are both nutrients. Although there can be a conversion from one form to the other, that conversion does not affect the net loss or gain of nutrients. Although nutrient issues are of concern to water bodies, it is absolutely necessary in a biological treatment system to have sufficient nutrients for the operation of the system to treat parameters such as BOD. The Georgia-Pacific facility is achieving a high level of treatment while managing its system at a minimum level of nutrient addition. Management of a treatment system requires attention not only to the influent and effluent, but also monitoring of conditions within the system itself to assure adequate treatment. Georgia-Pacific is continuing to refine its procedures for doing so. The State has adopted what is referred to as the "5- 5-3-1" (advanced wastewater treatment) limitation for municipal treatment plants that discharge to surface waters. This standard refers to five milligrams per liter for BOD, five milligrams per liter for suspended solids, three milligrams per liter for total nitrogen, and one milligram per liter for total phosphorous. This limitation has been in effect for many years and remains one of the most stringent state standards in the nation. Georgia-Pacific's facility would be in compliance with those standards for nitrogen and phosphorous. Effluent from the Georgia-Pacific mill increases the concentration of total nitrogen in Rice Creek, relative to background conditions. However, because of the relatively higher flow of the St. Johns River, when the load from the mill is transported to the St. Johns River, the increase in nitrogen concentration is so small as to be imperceptible. Nitrogen loading from Georgia-Pacific's Palatka mill on a long-term average (prior to upgrades of its treatment plant) has been measured at 1,196 pounds per day. The average loading at Buffalo Bluff, which is far upstream of Rice Creek and the Georgia-Pacific Palatka mill, is 36,615 pounds per day. Additional nonpoint sources contribute approximately 12,000 pounds per day in the study area. Thus, the loading from the Georgia-Pacific mill represents a 2.4 percent increase in nitrogen levels on the St. Johns River, a difference that cannot be measured. The largest point source of nutrients in the lower St. Johns River is the Buckman wastewater treatment plant in Duval County. That facility does not have nutrient limits on its discharge permit. Rice Creek does not provide any treatment (as opposed to dilution) for nitrogen in Georgia-Pacific's effluent. A review of probability distributions for nitrogen concentrations upstream and downstream of Rice Creek demonstrated that Rice Creek had no influence on nitrogen levels in the St. Johns River. Phosphorous concentrations from the effluent, if discharged to the St. Johns River, would dilute rapidly, decreasing to .2 milligrams per liter within the water column, five to six feet below the surface, after discharge from the diffuser, below the area in which light is absorbed at the surface of the water column. Chlorophyll-A is a parameter that is typically used as a measure of phytoplankton in the water column. Concentration distributions for chlorophyll-A at Buffalo Point (upstream of Rice Creek) matched concentrations for the same parameter at Racey Point, a station far downstream of Rice Creek. This analysis confirms that the inputs coming into the St. Johns River System from Rice Creek do not have a significant influence on the water quality of the St. Johns River, with respect to nutrients. With a discharge coming directly to the St. Johns River, and with nutrient loading being the same as from Rice Creek, the nutrient loading would not influence the St. Johns River. The Department does not have sufficient information at the present to impose a nutrient limit on Georgia-Pacific. The draft permit accounts for this issue through a re-opener clause which would authorize a limit when that information is available, if such a limit is necessary. Allegations Regarding "Deformities in Fish" Section J of the Petition includes allegations that Georgia-Pacific failed to provide reasonable assurances regarding adverse physiological response in animals under Rule 62-302.530(62), and that Georgia-Pacific has failed to provide reasonable assurances that its discharge will not be mutagenic or teratogenic to significant, locally occurring wildlife or aquatic species, or to human beings, under Rule 62- 302.500(1)(a)5. Petitioners suggest that the permit cannot be granted as proposed because it lacks effluent limits for (unstated) substances that are alleged to create potential violations of the free-from standard. This argument is barred as a matter of law for the reasons stated in the Order dated February 14, 2002. In addition, based on the following findings, this argument has been rejected because Georgia- Pacific has met the reasonable assurances standard without effluent limits on those unstated (and unknown) substances that are alleged to cause violations of those rules. Petitioners presented evidence that paper mill effluent in general contains chemicals which could cause the masculinization of the females in certain fish species, as well as hormonal effects in males. However, witness Koenig did not offer any testimony that Georgia-Pacific’s effluent, in particular, contained such chemicals. Dr. Koenig had collected no data and had not conducted any field studies in Rice Creek to support his testimony; rather, he relied on articles published by others and provided by Petitioner Linda Young. In agency practice and interpretation of the free- from standard in Rule 62-302.530(62), Florida Administrative Code, the question of whether a change is adverse depends on the overall community or population of that particular species. Tellingly, Petitioners did not present any competent evidence, through Dr. Koenig's testimony or otherwise, that Georgia-Pacific's effluent presents the potential for adverse effects on the overall community or population of any species. Dr. Koenig testified at length from his reading of studies performed by other scientists regarding changes in the hormone levels and gonadosomatic index (the relative weight of gonads) of fish in the St. Johns River in the vicinity of Rice Creek. In his testimony, Dr. Koenig relied on two published articles to address conditions in the vicinity of Rice Creek, both of which were primarily authored by M. Sepulveda. One of those articles showed hormonal changes taking place in a laboratory study where largemouth bass were exposed to mill effluent. That study also showed a change in the gonadosomatic index in the subject fish. Dr. Koenig did not offer any opinion that such changes would be adverse or that they would affect the reproduction of those fish. The other study was a field study with samples of fish at various regions in the vicinity of Rice Creek. This study did not include any fish from Rice Creek, but did include fish from the confluence of Rice Creek and the St. Johns River, as opposed to reference streams. The study showed lower levels of hormones in fish from the area of that confluence, but also showed similar effects at a reference stream 40 kilometers away. No testimony was presented to support the inference that the effects represented in the two studies were adverse, within the meaning of the free-from rule. Moreover, the data from those two studies were collected in 1996, 1997, and 1998, or before Georgia-Pacific converted its bleach plant to chlorine dioxide bleaching in March 2001. Therefore, Dr. Koenig had no data to support any theory that under current effluent conditions, Georgia-Pacific is producing or will produce compounds that would cause any changes of hormone concentrations in fish. With respect to the phenomenon of fish masculinization in Rice Creek, Petitioners' experts had no data to support a competent opinion on this subject. To support his testimony, Dr. Koenig only read one article that purported to demonstrate fish masculinization in 11-Mile Creek and the Fenholloway River, and one letter from an employee of the St. Johns River Water Management District [Young Exhibit 8A] that referred to "external anatomical anomalies" near Georgia-Pacific discharge points. The article attached to that letter and included in Young Exhibit 8A addressed data collected in Escambia County, and does not address conditions in Rice Creek. Petitioners attempted to present the theory that the potential for endocrine disruption or fish masculinization resulting from paper mill effluent would violate the free-from standard. As a condition to issuance of the permit, the Department proposes to require Georgia-Pacific to obtain approval of a plan of study to analyze the potential for significant masculinization effects from the discharge. Under the proposed conditions, Georgia-Pacific is required to determine the minimum concentration at which such effects may be detected. By its terms, the proposed permit may be reopened to adjust effluent limitations or monitoring requirements if the masculinization study shows a need for them. Department witness Brooks acknowledged a general concern for endocrine disruption resulting from paper mill effluent. In particular, Mr. Brooks referred to studies which showed that paper mill effluent could cause the elongation of an anal fin in the females of certain fish species. However, Mr. Brooks observed that although this appeared to be a physiologic response, there was no evidence or reason to believe that this effect was an adverse effect. Reports regarding masculinization, that is, the elongation of anal fins in female fish, are suspect because (among other reasons) the studies do not account for variances that would be expected based on the independent variables of sex, age, and growth. In any case, the data from those reports do not demonstrate significant, adverse effects in exposed populations. A critical and unbiased review of the published literature shows that impacts of masculinization are biologically interesting but preliminary in nature. Department witness Maher observed that the masculinization effect occurs naturally, and that the Department's plan of study is intended to determine whether this natural phenomenon becomes problematic or is enhanced by activity at the mill. Initial information reviewed by the Department indicates that the phenomenon is no longer experienced when a mill converts to a chlorine dioxide (ECF) bleaching process, as Georgia-Pacific has done in converting to ECF. According to witness Brooks, the observed effect known as "fish masculinization" is not confirmed to result from endocrine disruption. The Department has concluded that it has reason to be concerned about the potential for fish masculinization. From the Department's viewpoint, it is not clearly understood what is causing this effect. It has been shown that there is a direct relationship between concentration (or dilution) and the observation of those effects. This conclusion is consistent with Dr. Koenig's testimony, which observed a decline in observed effects based on the dosage or concentration of effluent. The Department has reviewed evidence showing that, with dilution, the effect of fish masculinization "go[es] away." In the Department's analysis of the fish masculinization issue in the present permit, the Department is requiring process improvements that would reduce this phenomenon, if it exists, in Rice Creek. In addition, if the discharge is relocated to the St. Johns River, the additional dilution would ameliorate the concern regarding fish masculinization, and the phenomenon will "go away." To give an even higher level of assurance that the resource will be protected, the Department is requiring a study to evaluate and confirm that the issue is resolved. The process changes required in the permit, the potential for further dilution in the St. Johns River if it becomes necessary, and the evaluations required in the permit condition render it very likely that any potential for fish masculinization will be mitigated. Thus, to the extent that fish masculinization could be deemed a violation of the free- from standard, Georgia-Pacific has provided reasonable assurances that it will not cause the masculinization of fish in the St. Johns River. Petitioners did not offer any credible evidence establishing that any specific compound or substance would cause the alleged effects of endocrine disruption or fish masculinization. Indeed, Dr. Koenig acknowledged that he was unable to find in his literature search the mechanism or chemical that is alleged to cause fish masculinization. Likewise, Petitioners were unable to suggest any concentration of that substance which would lead to those alleged effects. Dr. Koenig expressed a belief that chlorinated organic compounds from the paper manufacturing process may be responsible for endocrine disruption. Dr. Koenig also opined that within the general process of paper manufacturing, the bleaching process in particular was a concern. To the extent that Dr. Koenig may have had a concern regarding endocrine disruption from his review of studies performed using data from 1996 through 1998, it is reasonable to conclude that this concern is ameliorated by Georgia-Pacific's conversion to chlorine dioxide bleaching in March 2001. There is no evidence to establish a relationship between the presence or absence of dioxin and fish masculinization. Compliance with Dissolved Oxygen Standard (and BOD Concerns) In Section K, Petitioners disputed whether Georgia- Pacific had provided reasonable assurance of compliance with the adopted dissolved oxygen standard. The proposed permit contains different permit limits for BOD for winter and summer, because the impacts of discharges are different during those parts of the year. Georgia-Pacific has shown a substantial downward trend for BOD. The Georgia-Pacific facility discharges mass loadings of BOD at quantities which are much less than what is required to meet discharge standards. A review of effluent data shows that even for the worst period for performance, Georgia-Pacific's effluent was well below the proposed permit limits for BOD. A review of BOD discharges over the period of January 2000 to August 2001 demonstrates a consistent ability of the facility to meet the proposed permit limits, as well as a general trend of improvement that reflects Georgia-Pacific’s upgrade of the treatment system. Georgia-Pacific will meet the minimum standards for dissolved oxygen in mixing zones. With additional process improvements, Georgia-Pacific will also experience additional environmental benefits in the reduction of chemical oxygen demand. N. Dioxin and "Related Compounds" As to dioxin, Petitioners alleged in Section L of their Petition that Georgia-Pacific may discharge dioxin in concentrations that could cause a violation of the free-from standard. The proposed permit includes a permit condition for a plan of study to assess levels of "TCDD" and "TCDF" in fish tissue in the receiving waters. Department witness Brooks was unaware of any regulatory authority to require fish tissue sampling for dioxin. Department engineer Kohn was also uncertain of any regulatory authority for the Department to test for dioxin in fish tissue. Mr. Kohn agreed with the proposition that when a proposed permit condition is not specifically authorized by rule or statute, the condition must be withdrawn if the applicant objects. However, in this case, Georgia-Pacific did not object to the inclusion of a permit limit of .014 picograms per liter of dioxin in its final effluent. As noted above, Georgia-Pacific established that under its current effluent conditions, following conversion to chlorine dioxide bleaching, the facility is "non-detect" for dioxin. The Department does not have any adopted standards for fish tissue concentrations. Petitioners presented very little evidence of dioxin concentration in fish tissue following Georgia-Pacific's conversion to ECF bleaching, and they opposed the introduction of such data into evidence. A review of available data shows that there was not a statistically significant difference between the level of bioaccumulation of dioxin in fish tissue in Rice Creek versus a reference creek. The Florida Department of Health has concluded, based on review of prior fish tissue data, that a fish consumption advisory for Rice Creek was not warranted. Total Suspended Solids In Section M, Petitioners have alleged that TSS in the effluent would cause various environmental problems. However, Petitioners did not allege that TSS in the effluent would lead to a violation of water quality standards, and they did not present any accepted testimony or other evidence to support such a theory. There is no adopted water quality standard for TSS. According to the WQBEL Technical Report, effluent levels of TSS are generally comparable to background levels in the St. Johns River. The primary wastewater clarifier is designed to remove fiber or other settleable solids from the effluent before it travels to the secondary treatment system. Total suspended solids in Georgia-Pacific's effluent are primarily derived from biota in the treatment system, rather than fiber from the industrial process. Georgia-Pacific has shown a substantial downward trend for TSS. The facility reliably discharges TSS at quantities which are much less than what is required to meet proposed effluent limits. A review of discharge data for TSS demonstrates that Georgia-Pacific would perform in full compliance with the proposed permit limits. Petitioners presented no evidence to the contrary. Petitioners likewise presented no evidence to quantify any impacts from TSS. Color, the Transparency Standard, and Related Issues Petitioners have also alleged that the color in Georgia-Pacific's effluent would lead to nuisance conditions in violation of Rule 62-302.500(1)(a). However, they did not allege any potential violation of the one parameter traditionally associated with effluent color: the Department's transparency standard. Elevated levels of color in the effluent reduces the ability of light to penetrate into the water column, with potential effects on the growth of aquatic plants. This is translated into a "compensation point," that is, the water depth at which the light level reaches one percent. The state transparency standard prohibits a discharge from causing a decrease in the compensation point of more than ten percent, relative to natural background. The rate of decrease of light within a water column is related to increased color levels. Analysis performed by Georgia-Pacific's consultants shows that a ten percent change in compensation depth corresponds to a seventeen percent increase in color above natural background levels. Under the proposed permit, color was used as a surrogate, or alternative measure, for compliance with the transparency standard. Color was not used as a surrogate for any parameter other than transparency. Georgia-Pacific will, with additional process improvements, see additional environmental benefits in reducing the color of its effluent. For the purpose of the application, Georgia-Pacific's modeling analysis assumed that based on process improvements, its effluent would have a color of 1202 pcu. EPA's technical team had opined that Georgia- Pacific would, with process improvements, achieve a reduction in color to 500 pcu. Georgia-Pacific had opined that the improvements would achieve a color of 1202 pcu. Department witness Owen opined that the color reduction would be in a range between those two figures. Petitioners did not present any contrary evidence as to the ability of additional process improvements to reduce effluent color. Accordingly, using the most conservative (least optimistic) figure, Georgia-Pacific has provided reasonable assurances that before a discharge to the St. Johns River would be authorized, it will reduce the color of its effluent to 1202 pcu. The proposed permit takes into account the potential that Georgia-Pacific's process improvements will achieve greater improvements in color than anticipated. Under the proposed permit, the Department would reduce the size of the proposed mixing zone if Georgia-Pacific demonstrates that the color of its effluent is lower than projected. The modeling analysis further demonstrates that based on a discharge to the St. Johns River, assuming an effluent color of 1202 pcu, the change in compensation depth is greater than ten percent in the vicinity of the proposed diffuser. A 734-meter mixing zone for transparency would be required for a discharge to the middle of the St. Johns River. The required area for such a mixing zone is 64,000 square meters. Antidegradation Review In Section P, Petitioners have generally alleged that the Department failed to conduct a proper antidegradation analysis. More specifically, they alleged that the proposed discharge would reduce the quality of the receiving waters below the classification established for them. Because Georgia-Pacific presently discharges to Rice Creek, and because a separate relief mechanism (the Administrative Order) authorizes the discharge to Rice Creek, it appears that the antidegradation issues relate solely to the proposed discharge into the St. Johns River. If the relocation had resulted in degradation of the receiving water, the Department would have regulatory authority in its Rule 62-4.242(1)(c) to consider whether Georgia-Pacific could minimize its discharge through other discharge locations, the use of land application, or reuse. However, Petitioners failed to allege in their Petition that the Department misapplied that regulatory authority. Moreover, under Department practice, when a new discharge or relocation of a discharge will result in an environmental benefit, it is not necessary to conduct a review of other discharge options. The Department undertakes an antidegradation analysis in, among other scenarios, cases where a discharge will result in achievement of minimum water quality standards for a given designated use but will lead to an incremental lowering of water quality. The purpose of this analysis is to assure that the societal benefits of the discharge outweigh the cost of that incremental lowering. The proposed permit will not lead to the increase in discharge of any parameter, and the permit is more stringent and adds additional parameters or limits. In addition, there is a trend of improved performance for the treatment system. In the present case, the Department has concluded that the proposed project will result in a significant improvement in water quality by the reduction of pollutants associated with exceedences of water quality standards in Rice Creek. Regardless of whether the discharge remains in Rice Creek or is relocated to the St. Johns River, the proposed Permit and Administrative Order will lead to an improvement in water quality as opposed to a degradation of water quality. Based on improvements with respect to specific conductance parameters, the ability to relocate the discharge into the middle of the St. Johns River where better mixing will occur (relative to the confluence of Rice Creek), and anticipated improvements in grass beds, the proposed pipeline will lead to a net environmental benefit in the St. Johns River and Rice Creek. The project as set forth in the proposed Permit and Administrative Order will be clearly in the public interest because it will result in full achievement of water quality standards and full compliance with the designated use of the receiving water body. The project will result in a substantial reduction in pollutant loading in Rice Creek and the St. Johns River, regardless of the whether the discharge will be located in Rice Creek or in the St. Johns River. The Department adequately evaluated other discharge locations, alternative treatment, and disposal alternatives. Studies, including a land application pilot project, demonstrated that land application was not feasible based upon impacts to groundwater resources. In their Petition, Petitioners did not dispute the Department's analysis of those factors under applicable rules. Given these considerations, it is found that Georgia-Pacific has provided reasonable assurances that it will meet water quality standards, and it is evident that Georgia-Pacific will not reduce the quality of the St. Johns River below its Class III designation. Further, the proposed discharge will be clearly in the public interest for the purpose of antidegradation analysis. Further, the proposed discharge into the St. Johns River is important to and beneficial to the public health, safety, and welfare, taking into account the policies set forth in Rules 62-302.100 and 62-302.300, Florida Administrative Code. The proposed discharge into the St. Johns River will not adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats. Instead, the proposed discharge would provide a benefit to fish and wildlife, and their habitats. No persuasive evidence was presented that the proposed discharge to the St. Johns River would adversely affect the fishing or water-based recreational values or marine productivity in the vicinity of the proposed discharge. Indeed, the record demonstrates a beneficial effect as to those factors. The proposed discharge has not been shown to be inconsistent with the applicable Surface Water Improvement and Management Plan (SWIM plan). Rather, the evidence shows that the proposed discharge would promote the implementation of the applicable SWIM plan. Monitoring Issues Section Q in the Petition generally challenged the adequacy of proposed monitoring requirements. As to this issue, the monitoring conditions imposed in the proposed permit are sufficient to ensure compliance with the proposed permit. Petitioner Young's witness Gilbert agreed that the proposed monitoring conditions were adequate to determine the result of process changes, that the proposed monitoring conditions were comprehensive, and that those conditions were beyond what the Department normally required. The Department does not propose to engage in water quality sampling at the end of the diffuser or at the edge of the mixing zone because of the technical difficulties associated with such an endeavor. Instead, the process for determining compliance is to determine the condition of the effluent and simulate water quality conditions of the receiving water body under low-flow conditions (when the river would be most vulnerable to pollution discharges). Such an approach is more protective because it eliminates variables that may not be representative of worst-case conditions. The evidence shows that the size of Georgia- Pacific's facility renders it impracticable for Georgia- Pacific to compromise the integrity of sampling results, as suggested by Petitioners. Flow Limitations In their Petition, Petitioners also contended that the proposed agency action violates Rules 62-4.240(3)(a) and 62-620.310(9)(a) by failing to specify the volume of discharge or flows. Under Department practice, flow must be specified but is not necessarily limited. Flow was adequately specified in the proposed permit, where the facility is described as 40 MGD wastewater treatment facility with a 22 MGD expected average flow. Volume limits are indirectly set through the establishment of a mixing zone and through mass loading limits in the permit, such as the loading limits for BOD and suspended solids. When flow is increased and the concentration of the effluent remains constant, the flow would be limited by the mass limits in the permit. Furthermore, the pipe and diffuser will have a hydraulic limitation, that is, a physical limitation on the amount that can physically be discharged. The pipeline and diffuser are hydraulically limited to 60 MGD based on the current design. Over a ten-year period, Georgia-Pacific has shown a trend toward reduced effluent flow. For example, in 1991, Georgia-Pacific discharged just under 40,000,000 gallons per day (GPD). In 2001, the discharge was less than 24,000,000 GPD. As a result of water conservation measures, Georgia- Pacific has been able to achieve a substantial reduction in effluent flow even when it experienced increased storm water flow into the treatment system. Because of stormwater inputs into the treatment system, it is very difficult to set a flow limit on the discharge from a pulp and paper mill. Indeed, the Department does not typically impose volume limits on NPDES permits for pulp and paper mills. Where volume or flow limits are imposed on pulp and paper mills, they are necessary in order to assure compliance with a specific standard. The Administrative Order Georgia-Pacific has submitted plans and a reasonable schedule for constructing, installing, or placing into operation an approved pollution abatement facility or alternative waste disposal system. No contrary evidence was presented, and no alternative construction schedule was proposed by Petitioners. In assessing a schedule to achieve compliance, the Department considered the time necessary to construct additional improvements as well as the reasonableness of the time period in light of Georgia-Pacific's capital investment. As part of this analysis, the Department also considered Georgia-Pacific's commitment to go beyond what they were legally required to do in environmental upgrades. The schedule of compliance is reasonable, given the cost and magnitude of the improvements required of Georgia-Pacific. Georgia-Pacific needs permission to continue its discharge to Rice Creek for a period of time necessary to complete research, planning, construction, installation, and operation of an approved and acceptable pollution abatement facility or alternative waste disposal system. The time period described in the Administrative Order will enable Georgia-Pacific to maximize the operation of the process improvements in order to determine if the discharge can meet water quality standards in Rice Creek. Given the cost and magnitude of the improvements required in the permit and Administrative Order, the schedule of compliance set forth in the Administrative Order is reasonable. There is no present, reasonable alternative means of disposing of wastewater other than to discharge it into waters of the State. In their Petition, Petitioners contested the Department's general antidegradation analysis but did not allege that any alternative means of disposal were improperly overlooked. The Department does not have specific regulatory authority to require facilities such as Georgia-Pacific to consider re-use as part of its antidegradation analysis, as it does with domestic waste discharges. Nonetheless, the Department did look at re-use and land application and determined that they were not feasible alternatives. Although it was not specifically required to do so by rule, Georgia- Pacific had exhausted every reasonable means to re-use (rather than discharge) water from its facility. Under earlier authorizations, Georgia-Pacific was not required to achieve standards for color, conductance, and chronic toxicity in Rice Creek. The granting of an operation permit will be in the public interest. This is because Putnam County will suffer an adverse economic impact if the facility is shut down and there will be net environmental benefits achieved through compliance with the requirements set forth in the Permit and Administrative Order. The Permit requires Georgia-Pacific to submit a written report to the Department if it appears that a mixing zone is needed for chronic whole effluent toxicity.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Protection enter a final order (1) issuing proposed permit number FL0002763 to Georgia-Pacific Corporation, as set forth in Department Exhibit 175, and with the change in the permit conditions as requested in Georgia-Pacific Exhibit 102 and proposed by the Department during the hearing, and (2) approving Administrative Order No. 039-NE as set forth in Department Exhibit 176. DONE AND ENTERED this 3rd day of July, 2002, in Tallahassee, Leon County, Florida. ___________________________________ DONALD R.

Findings Of Fact THE PARTIES The Respondent is the successor agency to the Florida Department of Environmental Regulation and has permitting authority over the subject project pursuant to Chapter 403, Florida Statutes. The Respondent's file number for this matter is 311765419. Petitioner, Alden Pond, Inc., is a subsidiary of First Union National Bank of Florida and is the successor in interest to Orchid Island Associates. John C. Kurtz is the designated property manager for this project and appeared at the formal hearing as Alden Pond's authorized agent. THE PROPERTY AND THE VICINITY Petitioner has record title to all of Government Lot 9 in Section 15, Township 31 South, Range 39 East, less the Jungle Trail Road right of way, and all of Government Lots 2, 3, 6, and 7, Section 22, Township 31 South, Range 39 East, less the road right of way for State Road 510. Petitioner does not own land below the mean high water line of the Indian River, which forms the western boundary of the property. Much of the property, approximately the northern half, abuts a part of the Indian River that has been leased by the State of Florida to the United States Fish and Wildlife Service as part of the Pelican Island National Wildlife Refuge. The Pelican Island National Wildlife Refuge was the first national wildlife refuge established in the United States and has been declared to be a water of international importance. Upland of the proposed project is a golf course and residential development. The Indian River at the project site is within the Indian River Aquatic Preserve, which is classified as Class II Outstanding Florida Waters. The Indian River in the vicinity of the project is part of the Intercoastal Waterway system, is navigable by large vessels, and is an important travel corridor for manatees. The Indian River in the vicinity of the project is a healthy estuarine system. Minor deviations from Respondent's dissolved oxygen standards have been recorded. These minor deviations are typical and represent natural conditions for this type of system. Water quality sampling from March 1994 yielded no samples in which deviations from Respondent's dissolved oxygen standards were observed. THE ORIGINAL PROJECT On February 21, 1990, Orchid Island Associates submitted to the Respondent an application for a wetland resource permit to construct a boat basin and canal on its property adjacent to the Indian River. The artificial waterway that Petitioner proposes to construct on its property will, for ease of reference, also be referred to as a canal. Petitioner proposes to dredge from the north terminus of the canal to the Intercoastal Waterway a channel, which will be referred to as the hydrological channel. Petitioner proposes to dredge from the south terminus of the canal to the Intercoastal Waterway a channel, which will be referred to as the access channel. The original project involved, among other features, a canal approximately 6,400 feet long, the dredging of the hydrological channel and the access channel, the construction of 44 docks to be located along the eastern side of the canal, and the dredging of an area adjacent to the canal for a 58 slip marina. The width of the canal was to range between 100 and 200 feet. The original project required the filling of 4.72 acres of wetlands and the dredging of 8.81 acres of wetlands for a direct impact on 13.53 acres of wetlands. On January 15, 1991, Respondent issued a preliminary evaluation letter pertaining to the initial application that contained the following conclusion: "the project cannot be recommended for approval." On September 12, 1991, Respondent issued a Notice of Permit Denial dated September 12, 1991, which stated that the application would be denied. This denial letter did not suggest any revisions that would make the project permittable and represented a strong position by the Respondent that the project as originally proposed should be denied. The September 12, 1991, Notice of Denial correctly described the project site and the initial proposal as follows: . . . The proposed project is located north of and adjacent to County Road 510, north and east of Wabasso Bridge and adjacent to the eastern shore of the Indian River. The Indian River at the project site is within the Indian River Aquatic Preserve, which is classified as Class II, Outstanding Florida Waters. The Pelican Island National Wildlife Refuge, also an aquatic preserve and an Outstanding Florida Water, is immediately west of the project site. Historically, the site of the marina and its associated upland development consisted of a wetland adjacent to the Indian River and a large citrus grove. Subsequently, the wetland was surrounded by a dike and impounded for mosquito control purposes. At some point in the past, a borrow pit 1/ was excavated within the landward (eastern) edge of the impounded wetland. Most of the citrus grove has been converted to a residential community associated with a golf course. * * * The proposed project included excavation of a 6,400 linear ft. canal along the upland/wetland edge between the impoundment and the adjacent upland, dredging the existing borrow pit to a depth of -8 ft. NGVD to create a boat basin that will connect it to the excavated canal, construction of 58 boat slips within the excavated boat basin, excavation of two flushing channels through a portion of the impoundment dike and wetlands within the impoundment to connect the excavated channel to the Indian River and a natural lake within the impoundment, excavation of a 700 ft. long access channel to connect the excavated canal to the Intercoastal Waterway through the seagrass beds along the southern boundary of the project site, filling of 4.72 ac. of wetlands at three locations within the impoundment to create uplands, and construction of a boardwalk along the southern edge of the excavated canal through the wetlands in the impoundment to provide access to the marina basin. To mitigate for the loss of wetlands, the applicant proposes to enhance 68 ac. of wetlands within the mosquito impoundment by returning the impoundment berm to grade and implementing a rotary ditching project and open marsh mosquito management to improve the hydrology of the wetlands in the impoundment, planting high marsh species, and donating the enhanced wetlands to the State of Florida for incorporation into the Pelican Island National Wildlife Refuge through a lease to the United States Fish and Wildlife Service. The September 12, 1991, Notice of Denial provided, in pertinent part, the following reasons for the denial of the project: The Department hereby denies the permit for the following reasons: Water quality data for the Indian River adjacent to the project site indicates that the dissolved oxygen (D.O.) standard is not currently being met. The proposed 8 ft. deep canal and marina basin to the Indian River would be expected to result in introduction of additional low D.O. waters into a system which already does not meet the D.O. standard, thereby resulting in further degradation of the water quality in the Indian River. In addition to the D.O. problem, the project would result in water quality degradation due to the pollutant loading of marina related pollutants from the boats docked at the 58 slips that are proposed as part of the project in the marina basin. Additional water quality degradation also may result from boats that are moored at docks that may be constructed at a later date by the owners of the 44 lots adjacent to the canal, pursuant to the exemption in Section 403.813(2)(b), Florida Statutes. This exemption provides that private docks in artificially constructed waters are exempt from dredge and fill permitting and may be constructed without a permit providing they meet the size criteria listed in the statute and provided they do not impede navigation, affect flood control, or cause water quality violations. The boats in the canal system and boat basin would be a chronic source of pollutants for the life of the facility. The proposed water depths and slip sizes will make the basin accessible for use by large boats which can be expected to have on-board sanitation devices. The hydrographic report submitted by the applicant indicates the proposed waters will flush with a 2.6 hr. duration. Although this flushing rate will prevent water quality pollutants from being concentrated in the waters of the basin, it also will have the effect of transporting boat related pollutants to the Indian River, thereby causing degradation of the Outstanding Florida Water. The project site is within Class II Waters, prohibited for shellfish harvesting, but is adjacent to Class II Waters, approved for shellfish harvesting. Discussion with the Department of Natural Resources, Bureau of Regulation and Development, indicates that the pollutant loading from the project would probably cause the adjacent waters to be reclassified as "prohibited for shellfish harvesting." The reclassification of the adjacent waters would lower the existing use of the waterbody. Rules 17-302.300(1), (4), , and (6), Florida Administrative Code, state that: 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. * * * 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. As a result of the above cited factors, degradation of water quality is expected. The applicant has not provided reasonable assurance that the immediate and long-term impacts of the project will not result in the degradation of existing water quality in an Outstanding Florida Water and the violation of water quality standards pursuant to Rules 17-312.080(1) and (3), Florida Administrative Code, and Rule 17-4.242(2)(a)2.b, Florida Administrative Code. Specific State Water Quality Standards in Rules 17-302.500, 17-302.510 and 17-302.550, Florida Administrative Code, affected by the completion of the project include the following: Bacteriological Quality - the median coliform MPN (Most Probable Number) of water shall not exceed seventy (70) per hundred (100) milliliters, and not more than ten percent (10 percent) of the samples shall exceed a MPN of two hundred and thirty (230) per one hundred (100) milliliters. The fecal coliform bacterial level shall not exceed a median value of 14 MPN per 100 milliliters with not more than ten percent (10 percent) of the samples exceeding 43 MPN per 100 milliliters. Dissolved Oxygen - the concentration in all waters shall not average less than 5 milligrams per liter in a 24-hour period and shall never be less than 4 milligrams per liter. Normal daily and seasonal fluctuations above these levels shall be maintained. Oils and Greases: Dissolved or emulsified oils and greases shall not exceed 5.0 milligrams per liter. No undissolved oil, or visible oil defined as iridescence, shall be present so as to cause taste or odor, or otherwise interfere with the beneficial use of waters. In addition the applicant has not provided reasonable assurance that ambient water quality in the OFW will not be degraded pursuant to Rule 17-4.242(2)(a)2.b, Florida Administrative Code. In addition, pursuant to Rule 17-312.080(6)(a), Florida Administrative Code, the Department shall deny a permit for dredging or filling in Class II waters which are not approved for shellfish harvesting unless the applicant submits a plan or proposes a procedure to protect those waters and waters in the vicinity. The plan or procedure shall detail the measures to be taken to prevent significant damage to the immediate project areas and to adjacent area and shall provide reasonable assurance that the standards for Class II waters will not be violated. In addition to impacts to water quality, the project is expected to adversely affect biological resources. A portion (estimated at between 0.4 and 0.5 ac.) of the access channel alignment is vegetated by seagrasses, the dominant species being Halodule wrightii (Cuban shoal weed). Seagrass beds provide important habitat and forage for a variety of wildlife species. The loss of seagrass beds will result in a loss of productivity to the entire system that would be difficult to replace. The 4.72 ac. of wetlands proposed to be filled and the excavation required for the proposed channels (approximately 38 ac.) are productive high marsh and mixed mangrove wetlands which are providing wildlife habitat and water quality benefits. These wetlands have been adversely impacted by the freeze of 1989, but they appear to be recovering well. The proposed mitigation would provide some benefits through exotic removal and increased hydrologic connection to the Indian River. However, these benefits would not be adequate to offset the adverse impacts of the proposed wetland losses for this project. The project site and the adjacent Pelican Island National Wildlife Refuge are used for nesting and foraging by a variety of species, including little blue heron (Egretta caerulea) (Species of Special Concern (SSC)--Florida Game and Fresh Water fish Commission (FGFWFC)), reddish egret (E. rufescens) (SSC-FGFWFC), snowy egrets (E. thula) (SSC-FGFWFC), tricolored herons (E. tricolor) (SSC-FGFWFC), brown pelicans (Pelecanus occidentalis) (SSC-FGFWFC), roseate spoonbills (Ajaja ajaja) (SSC-FGFWFC), least tern (Sterna antillarum) (threatened-FGFWFC), and wood storks (endangered-FGFWFC). The construction of the project and the increased boating activity due to the project would result in the disturbance of those species that use the wetlands in the project area. The Indian River adjacent to the project site is used by the West Indian Manatee (endangered-FGFWFC). The increased boat traffic would increase the chance of manatee deaths due to boat impact. In addition, the excavation of the access channel through the seagrass beds would decrease the available forage for manatees in the project area. For the above reasons, this project is also not clearly in the public interest, as required pursuant to Section 403.918(2), Florida Statutes, because it is expected to: adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; adversely affect the fishing or recreational values or marine productivity in the vicinity of the project; be permanent in nature; diminish the current condition and relative value of functions being performed by areas affected by the proposed activity. The applicant has not provided reasonable assurance that the project is clearly in the public interest. On September 12, 1991, the owner and holder of the mortgage on the Orchid Island development (which includes the real property on which the Petitioner hopes to construct the project at issue in this proceeding) instituted foreclosure proceedings. The circuit judge who presided over the foreclosure proceeding soon thereafter appointed an interim receiver to manage the property until a receiver who would manage the property for the duration of the foreclosure proceeding could be appointed. THE PROJECT MODIFICATIONS AND FACTS AS TO ESTOPPEL On October 31, 1991, representatives of Orchid Island Associates met with Respondent's staff to discuss this application. Trudie Bell, the Environmental Specialist assigned to supervise this application, and Douglas MacLaughlin, an attorney employed by Respondent, attended the meeting. Those attending the meeting on behalf of Orchid Island Associates included the interim trustee, the attorney for Orchid Island Associates, and Darrell McQueen, who at all times pertinent to this proceeding was the project engineer. Mr. McQueen was upset that the project was going to be denied and wanted to know what could be done to make it a permittable project. In response to Mr. McQueen, Ms. Bell, without making any promises, suggested the following modifications to the project that might make it permittable: moving the canal more upland, elimination of the boat basin/marina, reducing the depth of the artificial waterway, and increasing the width of the littoral zone. On November 11, 1991, the representatives of Orchid Island Associates responded to the Respondent's suggested modifications and agreed to make the modifications. In an effort to design a project that would be acceptable to Respondent, Orchid Island Associates proposed to the Respondent to make certain modifications to the design of the project. Petitioner has agreed to those modifications which include the following: Elimination of the boat basin and associated 58 dock marina and clubhouse, but with the addition of 18 relatively narrow residential lots, each of which would have a dock on the south end of the waterway. 2/ Reduction of the depth of the artificial waterway to -7 feet NGVD from the proposed -8 feet NGVD. Realignment of the artificial waterway as depicted on the sealed drawings submitted to Respondent and dated January 28, 1993. Increasing the width of the littoral zone to be created along the length of the artificial waterway to 40 feet on the west side and 10 feet on the east side. On November 12, 1991, John C. Kurtz was appointed the receiver of the Orchid Island Associates property and remained the receiver until the property was conveyed to Petitioner at a foreclosure sale on July 31, 1993. After it acquired the property, Petitioner employed Mr. Kurtz to manage the subject property. Mr. Kurtz has been active in the project since his appointment as the receiver of the property. On November 21, 1991, Petitioner met with Respondent's staff, including Ms. Bell, to discuss the modifications. At that meeting, the Respondent's staff reacted favorably to the modifications agreed to by Petitioner. Ms. Bell described the revisions as "excellent" and "a great idea" and stated that the project was "a nice project" and that it looked like the project was heading in the right direction. Ms. Bell also represented that the Respondent would grant the Petitioner extensions of time to allow for a formal revision if the project was deemed permittable. Ms. Bell kept her superiors informed of the status of her review. On December 11, 1991, Charles Barrowclaugh, an employee of the Respondent, made an inspection of the site and informed representatives of the Petitioner that he had briefed Carol Browner, who was Secretary of the Department of Environmental Regulation, as to the project and the proposed modifications. Mr. Barrowclaugh stated that he believed the project was permittable. Petitioner was encouraged by Mr. Barrowclaugh's comments and by the fact that he would incur the expenses of traveling to the site. Between December 11, 1991, and November 13, 1992, Petitioner provided information to Respondent pertaining to the revised project. This additional information included a description of the revised plan and a revised schematic drawing, but it did not include detailed drawings of the revised project. On November 13, 1992, Ms. Bell wrote to Mr. McQueen a letter that stated, in pertinent part, as follows: The Bureau of Wetland Resource Management has reviewed the revised plan and additional information submitted on September 16. The revised proposal appears to address all of the issues that made the original proposal unpermittable. The detailed 8.5 by 11 inch permitting drawings will have to be revised to reflect the revised proposal and submitted to the Bureau for review. Kelly Custer and Orlando Rivera will be reviewing the project in the future. Petitioner interpreted that letter to mean that the Respondent intended to permit the project. At the time she wrote the letter of November 13, 1992, Ms. Bell thought the revised project would be permitted. Petitioner relied on the oral representations made by Respondent's staff and on the November 13, 1992, letter in continuing pursuit of a permit. Absent these encouraging comments by Respondent's staff, Petitioner would have discontinued pursuit of the permit. Although Petitioner was understandably encouraged by the discussions its representatives had with Respondent's staff, it knew, or should have known, that the favorable comments it was receiving from members of Respondent's staff were preliminary and that additional information would be required and further evaluation of the project would take place. Petitioner's representatives knew that the staff with whom they were having these discussions did not have the authority to approve the application, but that they could only make recommendations to their superiors. In late 1992, Kevin Pope, an Environmental Specialist employed by Respondent, was assigned as the primary reviewer of the revised project. At the time he became the primary reviewer of the project, Mr. Pope did not make an immediate, independent evaluation of the project, and relied on what other staffers who had been involved in the review told him. Until he conducted his own review of the project, Mr. Pope believed that the project was "clearly permissible". Mr. Pope informed a representative of the Petitioner of that belief and told the representative that he was prepared to start drafting the permit once he received final drawings documenting the modifications to the project. Subsequent to that conversation, Mr. Pope received the drawings he requested. After he received and reviewed the final drawings, Mr. Pope determined that all issues raised by the denial letter had not been addressed. Among the concerns he had was the fact that the project would dredge into the Indian River to the Intercoastal Waterway and that part of the dredging activity (at the north end of the project) would be in Class II shellfish approved waters. Mr. Pope again contacted the state and federal agencies that had originally commented on the project, described the proposed modifications to the project, and requested comments. Most of the agencies continued to object to the project. On August 5, 1992, Mr. Pope held a meeting with the commenting agencies and with representatives of the Petitioner to discuss the objections to the project. 3/ The agencies provided additional comments after this meeting and most continued to oppose the project. Mr. Kurtz testified that on June 1, 1993, Stacey Callahan, an attorney employed by Respondent, told him that she was attempting to draft the permit for the project. Ms. Callahan asked for sample wording for a restrictive covenant or for an easement that would limit the number of boats that could use the proposed docks. Subsequent to that inquiry, Petitioner was informed by Mr. Pope that the project would be denied. Petitioner has not made any specific proposal to assure a limitation on the number of boats that will be able to dock in the proposed canal. In June of 1993, a large number of objections to the project were filed with Respondent by members of the public. In early July, 1993, Secretary Wetherell responded to those objectors with a letter stating, in part, that the "Department's letter of November 1992 indicating an intent to issue for the project was imminent appears to have been premature." On September 20, 1993, Mr. Pope informed Petitioner's attorney that the Respondent was not going to change its position that the project, even with the modifications, should be denied. The decision not to permit the modified project was made by Mr. Pope. The only permit application filed by the Petitioner was the application for the initial permit. No formal amended application that incorporates all of the changes that Petitioner discussed with Respondent's staff was filed. A total of $74,735 was spent on behalf of the applicant on this project between December 26, 1991, (the date of the meeting with Mr. Barrowclaugh) and July 31, 1993, (the date the property was conveyed to Petitioner). From July 31, 1993, through April of 1994, Petitioner spent an additional $47,488 on the application for this project. The expenditures after July 31, 1993, included engineering costs that were incurred before that date. These figures do not include the costs of this proceeding. THE REVISED PROJECT The revised project may be summarily described as follows: Petitioner proposes to construct a canal that will be approximately 6,400 feet long, up to 200 feet wide, and -7 NGVD deep as depicted on drawings that have been submitted into evidence. There will be a littoral zone 40 feet wide on the west side of the canal and a littoral zone 10 feet wide on the east side. A hydrological channel, proposed from the north terminus of the canal to the Intercoastal Waterway to enable a proper flow of water through the canal, will be some 200 feet wide, 70 feet in length, and -3 NGVD. Petitioner proposes to construct a barrier at the north terminus of the canal to prevent manatees and boats from entering the canal from the north and has agreed to maintain that barrier. An access channel, proposed from the south terminus to the Intercoastal Waterway to enable boats access to the canal, will be some 200 feet wide, 700 feet in length, and -7 NGVD. A total of 62 docks are proposed. The project includes a mitigation plan that will be discussed below. THE REQUESTED VARIANCE The construction of the hydrological channel would be in Class II conditionally approved shellfish waters. Dredging in Class II conditionally approved shellfish waters is prohibited unless a variance is issued by Respondent that would permit this otherwise prohibited activity. Petitioner's attorney submitted a letter to the Respondent on August 18, 1993, for a variance to construct the channel from the north terminus of the canal to the Intercoastal Waterway. That letter stated, in pertinent part, as follows: DEP Rule 17-312.080(17) states: "Permits for dredging or filling directly in Class II or Class III waters which are approved for shellfish harvesting by the Department of Natural Resources shall not be issued." This provision is applicable to the pending application by Orchid Island Associates. Accordingly, we discussed Orchid Island requesting a variance pursuant to Section 403.201, Florida Statutes, and Rule 17-103.100, Florida Administrative Code, as a means of overcoming this prohibition. Since the dredge and fill application is pending, you indicated it would be appropriate for Orchid Island to ask, during final review of this application, that the Department also consider a request for a variance pursuant to the above mentioned statute and rule. Please consider this letter that request. . . . Petitioner did not submit along with its request the fee required by Respondent to process that request. Respondent did not advise Petitioner that it would not process its request without the requisite application fee until the prehearing stipulation was prepared for this proceeding shortly before the formal hearing. There was no evidence that Petitioner attempted to check on the status of its request for a variance or that it expected Respondent to act on the request for a variance independent of its final review of the overall project. As of the time of the formal hearing, Petitioner had not submitted to Respondent the fee that Respondent asserts is required before the request for the variance will be processed. Respondent asserted that position in the prehearing statement that was filed shortly before the formal hearing. The evidence as to the flow of water through the proposed canal assumed the existence of the hydrological channel from the north terminus of the proposed canal to the Intercoastal Waterway and the existence of the access channel from the south terminus of the proposed canal to the Intercoastal Waterway. CONSTRUCTION OF THE PROJECT The revised version of the artificial waterway will be excavated primarily from uplands, but the excavation will require that 3.6 acres of wetlands be filled and 7.1 acres of wetlands be dredged. The direct impact on wetlands will be at least 10.7 acres. The mitigation plan proposes that the berms around the mosquito impoundment will be leveled, the berm ditches will be filled, and certain rotary ditches will be dredged. The amount of wetlands to be impacted by that proposed activity was not established. The artificial waterway will be constructed utilizing a series of separate construction cells, a rim ditch, and filtration chambers. All excavated material will be disposed of on uplands. The construction system will filter most solids. Turbidity suppression devices will be used to minimize any turbidity associated with the excavation of the access channel at the south terminus and the hydrological channel at the north terminus. Petitioner established that its proposed construction techniques are consistent with best management practices. The small body of water that is referred to as the former borrow pit in the denial letter of September 12, 1991, is known as Boot Lake. Petitioner proposes to dredge the eastern end of Boot Lake, consisting of an area 800 feet by 180 feet (3.3 acres), to create part of the canal. The access channel at the south terminus of the canal will be approximately 700 feet in length and will have to be hydraulically excavated in the Indian River to connect the canal to the Intercoastal Waterway. The hydrological channel at the north terminus of the canal will be hydraulically excavated to connect the canal to the Indian River. The connection will require approximately 70 feet of dredging to -3 NGVD, which is the minimum necessary to maintain the proper flow of water through the canal. HYDROLOGY OF THE CANAL The artificial waterway will function as a flow-through system driven by a difference in the water surface elevation (the head difference) between the north terminus and the south terminus. The flushing of the artificial waterway far exceeds the Respondent's flushing requirement benchmark, which is a flushing time of four days. If a hypothetical pollutant's concentration is reduced to 10 percent of its initial concentration in four days, the flushing is considered to be acceptable. The flushing time for the system is approximately 2.6 hours, which will produce five total volume replacements per tidal cycle. The predicted flushing of the artificial waterway is quite rapid and energetic. The predominate flow of water in the artificial waterway is from north to south. At times, however, the flow will be from the south to the north. At the request of the Respondent, Petitioner conducted a tracer dye study within the Indian River at the proposed south terminus of the artificial waterway. No tracer dye study was requested for the north terminus. Although there was some disagreement as to the import of the tracer dye study, it established that pollutants introduced into the Indian River from the canal would be rapidly dispersed in the Indian River. WATER QUALITY - THE CANAL The artificial waterway will be classified as Class III waters of the State. Water quality within the artificial waterway will reflect the current water quality in the Indian River. Petitioner has provided reasonable assurances that the water quality within the artificial waterway itself will not violate state standards. Two potential sources of pollutants to the artificial waterway have been identified. The first source is stormwater runoff through the stormwater management system associated with the upland development. The second is pollution inherent with the docking and operation of large vessels. Respondent interprets its rules so that discharge of pollutants into the artificial waterway will constitute indirect discharges to the Indian River. Because of the excellent flushing capacity of the canal, pollutants will not tend to accumulate in the canal. A pollutant entering the canal or a spill of pollutants into the canal will mix very little in the canal, probably less than five percent, so the pollutant will discharge from the canal into the Indian River as a plug. There was a conflict in the evidence as to whether pollutants introduced into the canal will enter the Indian River in measurable quantities. Testimony was elicited from Dr. Roessler, one of Petitioner's experts, that water entering the Indian River from the artificial waterway will not contain pollutants that are either measurably or statistically differentiable from the Indian River itself. That result depends, however, on the amount and the source of the pollutant introduced into the canal. Because of the rapid flushing of the canal, small spills or slowly released discharges of pollutants are not expected to result in water quality degradation in the Indian River. Since a pollutant introduced into the canal will exit in a plug essentially in the same concentration as it entered the canal, Petitioner has not provided reasonable assurances that large spills or discharges of pollutants from vessels or from other sources will not be discharged into the Indian River in concentrations that can be measured or that such large spills or discharges will not degrade the quality of the Indian River. Water from the canal will come out of both the north end and the south end of the canal. Some of the plume coming out of the north end may tend to hug the shoreline, with some of the plume reentering the canal when the tides change. Stormwater runoff contains significant amounts of fecal coliform, sometimes more than raw sewage. The stormwater management system associated with the upland development was permitted by the St. Johns Water Management District. The majority of the system is currently in place and functioning to retain stormwater runoff. The stormwater management system is designed to retain all of the first 4.75 inches of rainfall and most of the first 6.2 inches of rainfall. The design of this system exceeds the requirements imposed by the St. Johns Water Management District, which is that the first 1.5 inches of rainfall be retained. Stormwater management regulations are technology-based treatment criteria. If a system meets the retention requirement, it is presumed that no water quality will be violated by discharges through the system. Petitioner established that the stormwater management system was designed and constructed to retain at least three times the amount of rainfall required by the St. Johns Water Management District. Construction of the proposed canal will intercept two stormwater discharge pipes from the upland golf course and residential development. There was no evidence that the St. Johns Water Management System has reviewed this change in the system that has been permitted. The proposed change in where the outflow will be discharged could be significant since the discharge pipes are presently designed to discharge overflows from the system into wetland areas that provided additional natural treatment of the overflow before the overflow reaches the Indian River. With this change the overflow will be discharged during extraordinary storm events into the canal and thereafter into the Indian River without additional natural treatment. Because there will be modifications to the stormwater system the approval of that system by the St. Johns Water Management District should not be relied upon as providing reasonable assurances that no water quality violations will be caused by stormwater discharge. If this project is to be permitted, Petitioner should be required as a condition precedent to the issuance of the permit to have the proposed changes to the system reviewed by the St. Johns Water Management District and it should be required to obtain an amendment to the stormwater management system permit that would authorize the proposed changes. The project contemplates the construction of 62 docks. The size and the docking capacity of each dock has not been established. While Petitioner presented testimony that it is likely that only 50 percent of the docks will likely be used at any one time, that testimony is considered to be speculative. The number and size of boats that can or will be docked in the canal at any one time or on a regular basis is unknown. It is likely that each dock will have docking capacity for at least one vessel up to 60 feet in length and for a smaller vessel. The manner in which these docks will be constructed was not established. Chromatic copper arsenic, which is frequently used to coat docks and anti-fouling paints containing heavy metals used on boats are sources of contamination to shellfishing. Oils and greases from boats contain hydrocarbons which can adversely impact shellfish. These contaminants can have adverse impacts to shellfish at very low concentrations. Petitioner has agreed to prohibit live-aboard vessels and to prohibit the fueling and maintenance of vessels within the artificial waterway. Sewage containing fecal coliform dumped or spilled from boats or from stormwater discharge is a primary source of contamination for shellfishing waters. It is the practice of the Respondent's Shellfish Environmental Assessment Section to close waters to shellfishing in the vicinity of marinas, mainly due to potential contamination from untreated sewage. The Shellfish Environmental Assessment Section does not recommend the immediate closing of shellfishing waters when a project involves single family docks associated with a residence because it assumes people will use bathroom facilities in the house instead of on the boat. The Respondent does not have reasonable assurances that there will be houses associated with each of the 50 foot lots designated at the southern end of the canal. If a proposed facility has boat docks, but does not have houses associated with each dock, the Shellfish Environmental Assessment Section would recommend closure of shellfishing in the vicinity of the facility. The Shellfish Environmental Assessment Section would not recommend immediate closure of the shellfishing waters in the vicinity of this proposed project because it has assumed that each of the proposed docks will be associated with a house. If this project is to be permitted, reasonable assurances should be required that a residence will be constructed before or contemporaneously with the construction of a dock. The modifications made by Petitioner to the project will reduce the danger of pollutants from vessels in the artificial waterway. However, because the number and the size of the vessels that will be using the artificial waterway was not established, the extent of pollutants from vessels is unknown. Consequently, it is concluded that Petitioner did not provide reasonable assurances that measurable pollutants would not indirectly discharge into the Indian River from the canal. IMPACT ON WETLANDS Of the approximately 10.70 acres of wetlands that will be directly impacted by the proposed waterway, 4.10 acres are predominately impacted by invasive exotic (non-native) plants, 4.27 acres are somewhat impacted by exotic plants, and 2.23 acres are not impacted by exotic plants. The exotic plants found at the project site are primarily Australian Pine and Brazilian Pepper. The mitigation plan, which will be discussed below, proposes that the berms constructed around the mosquito impoundment area be removed and the rim ditches that abut the berms be filled. The amount of wetlands to be impacted by that activity was not established. The project contemplates that rotary ditches will be constructed at different places in the mosquito impoundment area after the berms are removed and the berm ditches filled. The areas to be impacted by the construction of the rotary ditches were not identified. The Petitioner proposes to dredge out the entire east end of Boot Lake for use as part of the canal. This area will be approximately 800 feet by 180 feet and will be 3.3 acres. Boot Lake is a fairly healthy biological system, about the same as the Indian River. It was found to contain 22 species of fish and seven species of birds, with brown pelican and the great blue heron dominant. Eleven species of crustacean, six species of mollusks, 24 vermes 4/ and one coelenterate were collected from the lake. Replacement of the eastern portion of Boot Lake with the canal will adversely impact those species. Between the Indian River and the proposed waterway is a mosquito impoundment constructed in the early 1960s. The mosquito impoundment and associated berms total approximately 105 acres. The exact area was not established since there is an unresolved issue as to the exact location of the mean high water line. 5/ The impoundment is breached in several locations and no longer functions efficiently as a mosquito impoundment. IMPACTS ON SEAGRASSES The excavation of the access channel from the south terminus to the Intercoastal Waterway will involve the removal of approximately 2500 square feet of a healthy, productive seagrass bed. Seagrasses are beneficial for wildlife habitat as they provide a substrate for algae and diatoms. Seagrasses are a direct food source for manatees and other species, and provide shelter and protection for fish. Seagrasses observed in this area where grasses will be eliminated are Halodule writtii, Syringodium filiforme, and Halophia johnsonii. Halophia, one of the identified species in this seagrass bed, is designated by the Florida Natural Areas Inventory as a rare and endangered species. Besides the seagrasses actually eliminated where the channel is to be constructed, other nearby seagrasses are also likely to be affected. The sides of the channel are likely to slough to some degree, which would adversely impact the seagrasses abutting the channel. The operation of power boats, even at slow speeds, will cause turbidity that will likely adversely impact seagrasses. Maintenance dredging, which will be required every few years, will cause turbidity that will likely adversely impact seagrasses. There are presently thousands of acres of seagrasses located within the Indian River. There has been a historical decline in seagrass in the Indian River Lagoon. Since 1950, there has been a 30 percent loss of seagrasses and seagrass habitat. IMPACTS ON SHELLFISH The proposed project will have an adverse impact on shellfish and shellfishing. At a minimum, the project will require dredging in a shellfishing area. The hydrological channel that will be dredged to connect the north terminus of the canal with the Intercoastal Waterway will be located in Class II waters that have been conditionally approved for shellfishing. Both commercial and recreational shellfishing occur in the Indian River adjacent to the project site. The predominate flow of water through the canal will be southerly. There will be, however, a predictable northerly flow of waters that will cause waters from the proposed canal and any associated contaminants contained in those waters to flow from the north terminus of the canal into the Class II waters that have been conditionally approved for shellfishing. The proposed project may introduce a significant amount of freshwater into the adjoining shellfishing waters of Indian River, primarily in the vicinity of the north terminus of the canal. Any additional freshwater discharges to shellfishing waters is a concern because fecal coliform bacteria survive longer in freshwater than saltwater. Three likely sources of freshwater that would be added by this project to the Indian River in the conditionally approved shellfishing area were identified by Respondent. First, the proposed canal appears to be intersecting near its north terminus with a sulphur spring or artesian well which produces fresh water with a high sulphur content. Fresh water will likely be introduced into the canal from this source and discharged into the shellfishing waters when the tidal flow becomes northward. Second, freshwater may be introduced into the canal from the overflow pipes from the surface water management system. This source of freshwater would not be significant. Third, additional freshwater may enter the area after the berms around the mosquito impoundment area are removed as contemplated by the mitigation plan. The extent of this source of freshwater was not established. If this project is permitted, the Shellfish Environmental Assessment Section will monitor this area for water quality to determine if the area will have to be closed for shellfishing. This additional monitoring, for which Respondent will pay, will be required because of the potential adverse impacts this project presents to shellfishing. Because of evidence of deteriorating water quality, the Shellfish Environmental Assessment Section is recommending that the shellfishing waters adjacent to the site be reclassified from "conditionally approved" to "conditionally restricted". In "conditionally restricted" waters, shellfish can still be harvested, but the harvested shellfish have to be placed in designated waters or in on-land facilities so the shellfish can cleanse themselves of fecal coliform before going to market. The conditions in the area of the proposed project are not yet bad enough to prohibit shellfishing. IMPACT ON MANATEES There are approximately 2,000 manatees living in Florida waters, with approximately 1,000 living on the east coast and approximately 1,000 living on the west coast. The manatee is an endangered species, and the long-term survival of the species is not secure. The Indian River in the area of the proposed project provides good habitat for manatees and is a major travel corridor for several hundred manatees. Indian River County is one of 13 key counties that has been designated by the Governor and Cabinet to address special manatee concerns. Manatees traveling back and forth in this area usually use the channel of the Intercoastal Waterway because it is deeper and allows manatees an easier travel route. Speed zones for boat traffic are an effective manatee protection mechanism. The artificial waterway will be posted as an idle speed zone. The area where the access channel connecting the south terminus of the canal with the Intercoastal Waterway will be dredged is presently designated as a slow speed zone and the access channel itself will be marked. Petitioner has agreed to implement Respondent's standard manatee conditions. Seagrasses are an important source of food for manatees. The project contemplates that 0.05 acres of seagrass will be dredged, but that Spartina will be planted in parts of the littoral zone. While manatees eat Spartina to some extent, they prefer seagrasses. Since there are thousands of acres of seagrass located in the Indian River, it is concluded that the elimination of 0.05 acres of seagrass associated with this project is negligible and will not adversely affect manatees. A barrier to navigation will be maintained at the north terminus of the waterway to preclude boat access and limit access to the waterway by manatees. Manatees would be unable to enter or leave the artificial waterway via the north terminus. The artificial waterway will not attract manatees and should not, in and of itself, adversely impact manatees. The main adverse impact to manatees from this proposed project is the threat of collisions by boats that leave the canal and enter the waters of the Indian River, including the Intercoastal Waterway. At least ten West Indian manatees have been killed by boats in Indian River County since 1981. Even with the speed limits, the increase in boating in this area will present an increased risk to manatees. IMPACT ON BIRDS No species of wading birds, including those listed as endangered or threatened, nests or roosts within the project site. The project site is not currently heavily utilized by wading birds, but several species of wading birds were observed foraging for food in Boot Lake. It is reasonable to expect that dredging of Boot Lake and the increased boat traffic will have an adverse impact on birds. Diving birds, such as the brown pelican and least tern, will benefit from the increased open waterway created by the canal, which should serve as a feeding habitat. Wading birds congregate and nest in rookeries. The area of the proposed project is within the foraging range of 14 active rookeries, and it is reasonable to expect that those rookeries will be disturbed by the increased boat use or human activity that the project will bring to this area. Officials of Pelican Island National Wildlife Refuge have observed such disturbances and are opposed to this project. The pressure of human and boating activities on bird rookeries in the Pelican Island National Wildlife Refuge, including human intrusion into buffer zones established to protect the birds, has resulted in a continuing decline of the bird population since 1960. When disturbed by boats or by humans, the parent wading bird will often leave the nest, which exposes the eggs or the chicks to attack by predators or to overexposure to sunlight. Boaters will often cause wading birds who are foraging for food to flush, which disturbs their search for food. Certain species of wading birds are flushed more frequently and for longer distances when flushed from narrow tidal creeks in Spartina marshes (a habitat similar to the proposed canal) than in open shoreline habitat. IMPACT ON FISH The existing ditches inside the mosquito impoundment berms presently provide a habitat similar to that of a tidal creek for a variety of fish, including juvenile snook, tarpon, red drum, black drum, lady fish, and mullet. The proposed project will result in the filling of these habitats and impoundments. As a consequence of that activity, these species of fish will be adversely impacted by the project. Although Petitioner proposes to construct certain rotary ditches that it asserts would provide a habitat similar to that provided by the existing ditches, Petitioner has not submitted any plans or drawings or other specific information concerning these rotary ditches and has not provided reasonable assurances that these proposed rotary will replace the habitat that will be eliminated by the filling of the existing ditches. CUMULATIVE IMPACTS Other projects have been permitted on the Indian River north and south of the proposed project that have increased boat traffic on the Indian River in the vicinity of the project. The Respondent has not identified any similar projects which have been permitted in the vicinity within the last five years. The only similar application pending before the Respondent in the vicinity of the project is for two docks north of the project site. Although Respondent established that boat traffic on the Indian River has increased, this project is unique in scope and design, and it is concluded that Petitioner has given reasonable assurances that no negative cumulative impacts will be associated with the project. OTHER PERMITTING CRITERIA The parties stipulated to the following facts that pertain to permitting criteria: The project will not adversely affect navigation or the flow of water. The project will not cause harmful erosion or shoaling. The project will be of a permanent nature. The project will not adversely affect any significant historical or archaeological resources. The project will not adversely affect the property of others. The proposed waterway will be located almost entirely on private property in areas not currently utilized for fishing or other recreational activities. Except for the impacts on shellfishing, birds, and fish discussed above, the project will not adversely affect the fishing or recreational values within the vicinity of the project. THE MITIGATION PLAN Petitioner has taken all reasonable steps to minimize the adverse impacts associated with the type project it is proposing. Because there will be adverse impacts to an Outstanding Florida Water, the project can be permitted only if it is determined that the mitigation plan offsets the adverse impacts and makes the project clearly in the public interest. Petitioner's mitigation plan was contained in the original application and was revised between October 1991 and January 1992. Respondent considered the current mitigation plan in its review of this project. The current mitigation plan consists of the creation of wetlands, the enhancement of wetlands, and the preservation and donation of wetlands owned by Petitioner within the mosquito impoundment. The estimated cost of creation and enhancement of the mitigation plan is $600,000. Petitioner proposes to create approximately 14 acres of wetlands by removing the mosquito impoundment berms and converting other uplands within the impoundment to wetlands. These areas will be revegetated with various wetland plant species including red, black, and white mangroves. In addition, Petitioner proposes to create a forty foot wide intertidal littoral zone along the entire length of the western side of the artificial waterway and a ten foot wide littoral zone along the entire eastern side of the artificial waterway. Approximately three acres of the littoral zone will be created from uplands. The littoral zone will be revegetated with 80 percent cord grass and 20 percent red mangrove. Petitioner proposes to implement an open marsh mosquito control management program consisting of the elimination of natural accumulations of water in low lying areas within the impoundment by rotary ditching small channels to allow these areas to drain and to allow predator fish access to the areas. Petitioner will remove exotic plant species throughout the impoundment and will revegetate with native species such as red, black, and white mangroves. Petitioner proposes to monitor the project area to assure that exotic plant species do not re-colonize. The mosquito impoundment area and the associated berms is estimated as being approximately 105 acres. Because of the difficulty in determining the mean high water line and because of the number of breaches in the berms, the precise acreage within the impoundment area that is not currently sovereign lands was not established. If accurately surveyed, it is possible that the amount of acreage within the impoundment owned by Petitioner may be determined to be up to 10 percent less than is currently estimated. For the purposes of this proceeding, it is found that 105 acres is a reasonable estimate of the area of the impoundment owned by Petitioner. After completion of the enhancement program, Petitioner proposes to donate all the property it owns within the impoundment to the State of Florida. Petitioner asserts that it would have the right to construct single family docks from its property directly into the Indian River if this project is not permitted and that these docks would not be subject to Respondent's permitting jurisdiction. The construction of such docks would have an adverse impact on manatees and seagrasses. As part of its mitigation plan, Petitioner offers to waive its right to construct single family docks from its property directly into the Indian River. EVALUATION OF THE MITIGATION PLAN The wetland in the existing impoundment area is presently a good biological system that contains a good diversity of plants and animals. While Petitioner's proposals will enhance this area, the evaluation of that enhancement should take into consideration the quality of the existing system. There are at least three existing breaches in the berm system. Through these breaches there is some tidal influences and the export of detrital material. Because of the relatively isolated nature of the mosquito impoundment, it currently contributes little to the productivity of the Indian River. The removal of the berm system will result in greater tidal influence in the impoundment area. As a consequence, much of the leaf litter from mangroves within the impoundment that presently accumulates on site would be exported as detrital material to the Indian River, which will add material to the food chain. It is expected that increased tidal influence will also result in an improvement in the dissolved oxygen levels within the impoundment. The reestablishment of tidal influence within the impoundment area will increase habitat for fish, shrimp, and crabs, and therefore benefit the Indian River. Removal of the impoundment berms to reestablish tidal influences within the impoundment area will increase and improve feeding and forage habitat for wading birds. Consequently, wading birds that nest in the vicinity of the project will be benefited. Increased tidal influence will likely result in better growth for mangroves which would create roosting sites for wading birds where none presently exist. Currently, Australian pines are the dominate species in areas within the impoundment area. Other areas of the impoundment are heavily populated by Brazilian pepper. Australian pines and Brazilian peppers do not serve as food sources for any native wildlife and have the potential to crowd out native plant species such as mangroves. If not removed, the potential exists for Brazilian pepper to become the dominate plant species. Removal of exotics and replanting with native species is a benefit to the Indian River system. With an appropriate monitoring plan, the exotic removal should be successful. If the project is permitted, the implementation of an appropriate monitoring plan should be a condition of the permit. Because of widespread mosquito control activities, the high marsh ecosystem is now rare in the Indian River system. The restoration of the impoundment area to an area of high marsh would be of benefit to the Indian River ecosystem. Prior to alteration by man, the mosquito impoundment was a high marsh ecosystem consisting primarily of black and white mangroves over an understory of succulent plants. There was a conflict in the evidence as to whether the Petitioner's proposals would result in the impoundment area returning to a high marsh area. While the impoundment area will be enhanced by the Petitioner's proposals, it is found that whether the area will be returned to a high marsh system is speculative. The mosquito impoundment is breached in various locations and, as a consequence, the impoundment is not functioning to control mosquitoes as it was originally designed. The current primary mechanism for mosquito control within the breached mosquito impoundment is aerial spraying of insecticides. The proposed removal of the existing berms will not adversely affect mosquito control and may positively affect mosquito control due to the increased accessibility of the impoundment by natural predators such as fish. This open marsh management plan is an effective means of controlling mosquitoes. The wetland creation proposed by Petitioner should have a high rate of success. Petitioner has agreed to implement a suitable monitoring plan to further guarantee the success of the proposal. If the project is permitted, the implementation of a suitable monitoring plan should be a condition of the permit. Scraping down the mosquito berms will create more wetlands, but the earth from the berms will be placed in the adjacent ditches, which presently serve as valuable tidal creek type habitat. Therefore, the mitigation itself will have some adverse impact. Petitioner's unspecified proposal to put in some rotary ditches to offset the loss of tidal creek habitat is inadequate in that there has been no specific proposal as to the location, size, shape, configuration, or acreage of the proposed rotary ditches. While planting of the littoral zones on the edges of the canal with Spartina provides some biological value, the growth of Spartina on the ten foot ledge on the east side will be impacted by boats and docks. The littoral zones will likely perform valuable wetland functions if properly planted and monitored and will likely become a productive wetland system that will provide habitat for wading birds. If the project is permitted, the Petitioner should be required to monitor the Spartina planting to ensure its successful growth. Even if the creation of the 13.9 acres of wetlands is successful, it will take years to become a mature biological system similar to the wetlands they are to replace. This time lag should be taken into account when evaluating the mitigation plan. There are adverse impacts from this proposed project that the mitigation plan does not offset. The mitigation plan does not offset the elimination of seagrasses, the loss of the Boot Lake habitat, the potential adverse impacts to shellfish and shellfishing, or the impacts to manatees. It is likely that property owners wishing to construct docks directly into the Indian River would have to get a permit from Respondent to gain access to the parts of the property where these docks could be constructed. Any proposal to extend docks into the Pelican Island National Wildlife Refuge would likely be prevented by the U.S. Fish and Wildlife Service. Whether such docks would, or could, be constructed is speculative, and this portion of the mitigation plan should be accorded little weight. As part of its mitigation plan, Petitioner proposes to donate approximately 105 acres to the State of Florida. This is considered to be a favorable aspect of the mitigation plan. The central issue in this proceeding is whether the mitigation plan offsets the negative impacts of this project so that the project becomes "clearly in the public interest." This issue is resolved by finding that even when the mitigation plan and the conditions that are recommended herein are considered, this project is "not clearly in the public interest."
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Respondent enter a final order that adopts the findings of fact and conclusions of law contained herein and which denies the modified application for the subject project. DONE AND ENTERED this 31st day of August 1994, in Tallahassee, Leon County, Florida. CLAUDE B. ARRINGTON Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 31st day of August, 1994.
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.
