The Issue Whether Okaloosa County has provided reasonable assurances that its proposed sewage treatment plant and an associated reclaimed water reuse system will not cause pollution significantly degrading the waters of the unnamed stream on the project site and/or the Santa Rosa Sound and that therefore the County's application for a permit to construct such facilities should be granted on the basis of assurances of compliance with applicable rule and statutory criteria.
Findings Of Fact On October 16, 1987, Respondent, Okaloosa County, submitted an application to Respondent, Department of Environmental Regulation, to construct a wastewater treatment plant and related reclaimed water reuse facilities on a site located in southwestern Okaloosa County. The Petitioner is an individual citizen residing in Okaloosa County, Florida. He is the owner of real property which adjoins the northern boundary of the proposed project site. Mr. Ward has used this property as his principal residence for approximately 8 years. The proposed project site is located in southwest Okaloosa County contiguous to the western boundary of the County. The site comprises approximately 45 acres of land bounded on the west by Rosewood Drive and on the south by State Highway 98. The areas to the north and east are residential construction. The site is currently a densely wooded area vegetated with a variety of flora indigenous to the area. The site is essentially bisected by a small fresh water stream system which enters the site at the northwestern corner and runs diagonally to the southeastern corner where it flows through a series of culverts under State Highway 98. The stream system constitutes waters of the state subject to the Department's regulatory jurisdiction. In addition, there is an isolated wetland area of variable size in the northwestern section of the project site. The wetland area is not subject to the Department's regulatory authority. The stream system mentioned above intersects with another larger stream approximately 1000 feet southeast of the project site. These combined streams then meander into a tidal basin which empties into the Santa Rosa Sound approximately 2500 feet south of the project site. The Santa Rosa Sound has been designated as Class II waters of the state. The unnamed stream system on site, as well as the larger stream that it joins south of the site, are designated as Class III waters of the State. Southern Okaloosa County occupies a region of moderate elevation (0-70 feet above sea level) extending along a strip 10 or 15 miles wide along the coast of the Gulf of Mexico. Soils in this area are predominately fine sands low in organic matter. When dry, most of the soils have rapid internal drainage characteristics. The Plant The proposed plant is intended to treat sewage generated by the County's Western subregional service area. Initially, it will treat the flow currently handled by approximately 1400 septic tank systems and 9 package treatment plants within the area. The collection system which will transport the wastewater will be comprised of approximately 98,500 linear feet of 8 to 12 inch diameter gravity sewers. The transmission facilities to convey the raw wastewater from the new collection system will include the construction of approximately 29,400 linear feet of 4 to 10 inch diameter force main, 14 pump stations and approximately 32,100 linear feet of 8 to 12 inch diameter gravity interceptors. By the end of its first year of operation, the proposed facility is projected to receive and treat approximately 750,000 gallons per day ("GPD"). The projected flow through the wastewater facility in the year 2007 is 1,000,000 GPD. The proposed facility is best described as a 1,000,000 GPD capacity oxidation ditch treatment plant with nitrification and denitrification facilities. Reclaimed water reuse will be accomplished by a rapid infiltration basin system (RIB). Sludge from the system will be dewatered by a mechanical belt press system and disposed of at the County landfill. In order to address the question of potential odors which result from the operation of the plant, the facility was located as near the center of the property as possible in order to give as much buffer area as possible between the facility and the surrounding residential area. In addition, the design of the treatment facility incorporates a preprocess aeration tank equipped with an activated carbon airstripper system which is specifically designed to remove the odor from the wastewater influent. The treatment facility was also located near the center of the property in order to keep any noise resulting from the operation of the plant as far away from the surrounding area as possible. The plant utilizes noiseless gravity flow techniques and does not incorporate any blower or pump technology which usually cause a significant amount of noise in wastewater treatment plants. It is expected that the noise level from the operation of this facility would be less than the noise level generated from the traffic on State Highway 98 nearby. The plant is designed to minimize the adverse effects resulting from odors, noise, aerosol drift and lighting. The entire facility is enclosed by a fence. The facility is designed and does comply with the Florida Administrative Code requirements for protection from flooding. The proposed site is at a higher elevation than the established 100 year flood elevation for the area. The plant is designed so that every operational component of the plant has a backup system. The plant is equipped with an emergency generator capable of supplying sufficient power to operate the plant in the event of a power failure. The design of the plant complies with the standards provided by the Environmental Protection Agency for mechanical reliability. The information submitted for the Department's review in relation to the County's construction permit application addressed all the information required in Rule 17-6.037(10), Florida Administrative Code. The proposed plant facility is designed to leave a buffer zone approximately 200 feet wide between the reclaimed water reuse system and the stream system located on the project site. The construction plan prohibits any construction activities and/or clearing within the buffer area. This buffer area contains all the jurisdictional areas which are related to the stream system. The Treatment Process The waste treatment process proposed for this facility consists of secondary treatment, basic disinfection and pH control as defined in Rule 17- 6.060(1)(a)3, (c) and (d). The basic treatment process technology used in the proposed plant is described as a carousel activated sludge process. This process is a superior method of wastewater treatment because of its inherent stability, its reaction to shock and toxic loadings and the degree of process control that is available to the operator. The effluent limitations that the Department has established for this facility require that the effluent, after disinfection, contain not more than 20 mg/1 Biological Oxygen Demand ("BOD") and 20 mg/1 Total Suspended Solids ("TSS"). In addition, effluent standards require a basic level of disinfection which shall result in not more than 200 fecal coliform values per 100 ml of effluent sample. The chlorine residual in recovered water shall be maintained at 0.5 mg/1 minimum, after 15 minutes contact time at peak flow. The pH level in the effluent must be maintained in a range between 6.0 Q and 8.5. The County will be required to retain a Class B operator certified under the provisions of Chapter 17-16, Florida Administrative Code for day-to- day maintenance and operation of the treatment facilities. In addition, the facility must be staffed for a minimum of 16 hours per day, seven days a week by at least a Class C operator certified under the same provisions. A Class B operator shall be on call during all periods that the plant is unattended. At a minimum, the facility must produce reclaimed water which complies with water quality standards provided in Rule 17- 3.404, Florida Administrative Code, as it interacts with groundwater in the established zone of discharge ("ZOD"). The estimated ZOD is an area defined by the boundaries of the facility. These standards are essentially equal to drinking water standards provided in Rule 17-22, Florida Administrative Code. Because the soils under the site are rapid sands, the Department does not rely on them to significantly reduce total nitrogen in the reclaimed water through interaction with the soils and the groundwater table under the rapid infiltration basins. As a result, the proposed facility is limited to a Total Nitrogen limitation of 7 mg/1. This limitation is significantly less than the Department's rapid rate land application treatment standard for Total Nitrogen which is 12 mg/1 in the effluent, with no more than 10 mg/1 in the ground. The proposed plant is capable of producing the 7 mg/1 level under all flow conditions. The Rabid Infiltration Basins In conjunction with the County's application for a construction permit for the wastewater treatment plant itself, the County submitted an application for a reclaimed water reuse system construction permit for a system designed to handle the maximum plant discharge of 1,000,000 gallons of reclaimed water per day. The system is composed of a series of five rapid infiltration basins (RIB's) or percolation ponds designed to receive the daily reclaimed water loads from the operation of the plant and allow the water to percolate into the groundwater beneath the project site. The ponds are proposed to be used so that not all the ponds are working at the same time. On any given day, there will be 3 ponds receiving effluent from the plant and 2 ponds receiving no effluent. The proposed system of rapid infiltration basins is the best approach to effluent disposal on this particular site in consideration of a variety of site specific criteria. While the Department's adopted guidance standards for percolation pond location specifies that areas with average depths to the groundwater table of 10 feet or more are desirable, the guidance document provides that areas with lesser depths may be acceptable. Computer models using highest projected groundwater levels and highest reasonably projected mounding effects related to the effluent disposal system indicate that while at times there may be less than 3 feet of vertical separation between the top of the groundwater mounds beneath any one of the percolation ponds and the floor of those ponds, it is not expected that the groundwater level will intersect the bottoms of the infiltration basin and that an acceptable margin will be maintained. Initially, there was some dispute among Department staff concerning the suitability of the project site to handle the hydraulic loading rates proposed for the facility's pond system. After a significant amount of analysis of the relevant factors affecting site suitability in this regard and after Department staff managed to get the computer program which analyzes this data working properly, the relevant data indicates that the site is suitable for the proposed wastewater treatment plant as designed. Surface and Ground Water Impact The proposed facility is designed to meet applicable Department water quality standards necessary to prevent unacceptable degradation of the water quality in both the unnamed stream system on site and the Santa Rosa Sound. At the Department's request, the County had an independent study performed to assure that the operation of the facility would not have the effect of degrading nearby surface waters. This study, done by Larry Jacobs and Associates, supports the County consultant's projections that, under worst case conditions (highest observed groundwater levels plus maximum effluent loading), approximately 32,000 additional gallons per day of groundwater may enter the stream system as a result of operation of the RIB system. These studies were conducted to address the Department's concern about the potential for increased nitrogen loading into both the stream system and the Santa Rosa Sound as a result of increased groundwater contributions to the stream system on site. The effluent disposal study submitted by the County as part of its application concludes that, discounting any possible reduction of Total Nitrogen content of the effluent as it travels through the ground before its discharged into the stream system, the Total Nitrogen concentration of the groundwater predicted to reach the stream should be diluted at the lowest observed flow volumes in the system to a concentration of less than 1 mg/1 when it reaches the confluence of the two streams approximately 1,000 feet south of the project site. The projection is an improvement in surface water conditions when compared with currently observed average concentrations of Total Nitrogen in the stream system and Santa Rosa Sound of 1.24 mg/1. The performance of existing package plants in the area is generally poor. In fact, one treatment plant was ordered to close, forcing the relocation of residents in its service area. Another plant has continuing groundwater nitrate violations. In addition, the evidence shows that the performance of the septic tank systems in the area is not acceptable to the Environmental Protection Agency. The majority of the population is served by septic systems that fail under high groundwater conditions. The Director of the Okaloosa County Health Department has certified that 60% of the residents in the County West Service Area have failed septic tanks and that the remaining 40% have septic tanks in imminent danger of failing. Three of the eight existing treatment plants are under either Court or Consent orders to cease operations. The United States Environmental Protection Agency has found that the County West area has an immediate need to provide collection, transmission, and treatment facilities to protect surface and groundwaters and eliminate a public hazard. Existing concentration of Total Nitrogen in Santa Rosa Sound and the waterways on and adjacent to the site are attributed to discharge of inadequately treated wastewater from existing septic tanks, existing wastewater treatment plants and stormwater runoff in the area. It is unlikely that the nitrogen concentration in the Santa Rosa Sound will increase as a result of the operation of the proposed facility since whatever wastewater treated at the facility will be eliminated from discharging into the affected waterbodies from other, less efficient treatment facilities. The proposed facility design incorporates a total of seventeen monitoring wells or stations on and around the site. Two wells will monitor background groundwater quality upgradient from the percolation pond system. Twelve wells will monitor groundwater quality down gradient from the percolation pond system as it leaves the established zone of discharge. Two more stations will monitor surface water quality in the on-site system above and below the site. In addition, there is one intermediate monitoring well within the zone of discharge. Samples from these wells will be used to provide quarterly data reports to the Department indicating status of the following parameters in the ground water; water level, pH, BODs, Fecal Coliform, Total Nitrogen, Nitrate/Nitrate and Chloride. The surface water monitoring will provide annual data reports to the Department on the following parameters: Chemical/Physical - Total Nitrogen, Nitrate/Nitrate, Total Phosphorus, Dissolved Oxygen, Temperature and pH Biological Assessment - macroinvertebrate population per species, species diversity per square meter. These data reports will be submitted regularly to the Department in conjunction with operational monitoring data from the treatment plant to allow assessment of the impact of the plant operation on the environment and compliance with permit conditions. Clearly the County has provided reasonable assurances that the proposed plant and related facilities will not cause pollution significantly degrading the waters of the State.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Regulation enter a Final Order Granting the application of Okaloosa County to construct a wastewater treatment facility and related reclaimed water reuse system at the proposed site in southwestern Okaloosa County, Florida, and issuing permits in accordance with the conditions as set forth in the Department's Intent to Issue and draft permit dated August 1, 1988.

Findings Of Fact On a site that would abut St. Johns County on two sides, the City proposes to develop as a landfill about 400 of the 880 acres it owns in the southeast corner of Duval County. The proposed southeast landfill is designed to serve the approximately 300,000 people living in Duval County south and east of the St. Johns River, by receiving 1,700 tons of solid waste a day for ten years, 400 or 500 tons a day more than people in that part of the city now generate. Sandhill and Swamp Scattered over the portion of the property proposed for solid waste deposition are cypress marshes and blackgum sloughs isolated from a swamp and from each other by upland pine plantation and sandhills. Except for some 40 acres cut off from the remainder by a fill road, the hardwood swamp covering approximately 265 acres of the City's property is part of the pristine "Durbin Swamp system which is a major wildlife area, including habitat for threatened and endangered species." T. 2820. Durbin Swamp south of J. Turner Butler Boulevard and east of U.S. Highway 1 is "the most valuable wildlife habitat in the area, maybe in the southeastern United States." T.2921, 3058. The City's consultants characterized 64 of the 123 gopher tortoise burrows they found on some 105 acres in the southern part of the site as active. Sherman's fox squirrels feed and nest on the property. Although "very little of the sand hill habitat [remains] in its natural condition on the property," (T. 185) turkey oak, long leaf pine and sand pine communities do survive. Isolated wetlands scattered through the eastern portion of the site have also been timbered, and ditches intersect many of them. St. Regis Paper Company, who owned the land until earlier this decade, "dug a series of canals . . . to drain . . . part of the land ["it was called upper wetlands"] . . . so that the ground could be high enough to raise good grade pine trees." T. 1417. "The isolated wetlands . . . provide habitat diversity for wildlife, a seasonal source of drinking water, possible refuge during forest fires, as well as breeding and forage locations," (T. 1255) according to the City's draft application. "Wildlife noted on the site includes Florida black bear, white-tailed deer, raccoon, armadillo, cottonmouth, river otter, common night-hawk, alligator, yellow bellied sapsucker, turkey, frog, quail, dove and red- shouldered hawk," (T. 1255) also according to the City's draft application. Bobcats are common. According to the St. Johns River Water Management District's chief environmental specialist, "animals that you would find utilizing the uplands . . . would be a range of small rodents [including] mice, rabbits . . . insects, [mostly tree] frogs, toads, snakes [including] black snakes, rat snakes . . . [o]possums . . . pastorine birds, cardinals, bluejays, blackbirds . . . [and] probably some hogs." T.537-8. Wood storks wade and feed in the isolated wetlands on site. Wood stork rookeries have been found five miles to the southeast and seven miles north of the City's property. Bald eagles nest nearby but off site. Eagles used the now abandoned eagle nest on Eagle Nest Island "three-quarters of a mile from this proposed landfill site," (T. 1419) at least as recently as 1983. One or more eagles still perch on a dead cypress limb on the property (T. 2422), if not elsewhere on site. Ospreys, southeastern American kestrels (T.2918) and six or seven species of woodpeckers, including the rare hairy woodpecker (T2914) have also been seen on site. "There are dirt logging roads just as there are in any property in Florida, but not a great number." T. 2751. "Almost all of the pine flatwoods habitat on the site has been replaced with planted pine." T. 184. The property is comparable to the Wacasassa tract in Gilchrist County which is on the Conservation and Recreational Lands list and under consideration for state acquisition because of its "comparatively unaltered nature." T. 2721. In the past, conservation efforts have brought animals to the property for refuge. T. 1420. Listed Species The Florida Game and Freshwater Fish Commission (Game and Fish) lists the gopher tortoise and the Shermans's fox squirrel, said by one witness to be "imminently threatened," (T. 2899) as species of special concern. T. 2875. A species of special concern "is beginning to show a decline and needs to be . . . considered as a target of conservation and if present conditions continue it's going to be listed as threatened." T.2874. Game and Fish lists the Florida black bear, the southeastern American kestrel and the bald eagle as threatened, the same category in which the United States Fish and Wildlife Service (Fish and Wildlife) lists the American alligator. A threatened species is one destined to become endangered "if present trends continue." T.2874. Both Game and Fish and Fish and Wildlife list the wood stork as endangered, and Fish and wildlife lists the bald eagle as endangered. "An endangered animal is one that under present conditions is in danger of becoming extinct in the near future." T.2874. Listed in the Convention on International Trade of Endangered Species are the bobcat and the river otter. By definition, rare animals are not often seen in the wild. The parties stipulated that the staff of CZR, Inc., a consultant engaged by the City, spent an aggregate of 1400 man-hours on the landfill site, of which 429 man-hours were spent on site for the purpose of performing a wildlife survey. T. 2803. Despite their effort and putative expertise, the City's consultants did not see even a single listed animal. This failure contrasts with sightings by hunters and other experts who spent less time on site, and may be attributable to the time of year (two weeks in the fall) the survey was performed (T. 2425-27, 2893, 2899) or to the way in which it was done, (T. 2429, 3067, 3068) which a wildlife ecologist testified rendered it of "trivial value." T. 3079. The study was expedited in anticipation of a hearing date. T. 2426-27. In any case, the survey does not give reasonable assurance that species whose range includes the City's property are not present in suitable habitat on site. T. 2896-97, 3079-80. This is, indeed, the conclusion the City's own experts reached as regards the gopher tortoise itself, because of the clear sign these creatures' burrows give of their use of the property. Similarly, with respect to the Sherman's fox squirrel, although only a single individual was spotted, distinctive nests and piles of pine bracts on site established their presence. Bear tracks corroborate infrequent sightings on the property, as well as south and east of the site. On a large tract of land to the north, bears are fed daily; three or four feed each day. T. 2421. Alligator sign bore witness to the alligator's use of the property, although the only sighting clearly proven at hearing occurred just across the boundary line. Of course, wildlife does not respect legal boundaries. There is no reason not to believe that the red-cockaded woodpeckers, with six active nests within three miles or the Bachman's sparrows heard singing nearby do not frequent the City's property, which offers suitable habitat for both. It is even possible that the Florida panther, common in the area as recently as 30 years ago, may have roamed the site in more recent years in pursuit of deer or feral hogs. Two witnesses swore they had seen Florida panthers within two miles of the site, one only a few months before the hearing, (T. 1362, 1371, 1419), and a third testified he thought a "cat" he had seen two and a half or three years before the hearing just north of the site was a Florida panther. T.2429-32. The Florida Everglades mink, a threatened species according to Game and Fish, has been spotted at least twice in a cypress bog across the street from the City's property, and probably occurs on the property, as well. Not spotted either on the City's property or on adjacent land, the Florida mouse, the eastern indigo snake and the gopher frog are known to make their homes in gopher tortoise burrows. Of these listed commensal species, the indigo snake is particularly likely to inhabit the site. "The blue indigo snake was turned loose on that property in . . . '81 or '82, since it was an endangered species." T. 1420. The site also affords suitable habitat for the long tailed weasel, under review for listing. Game and Fish has listed the Florida mouse and the gopher as species of special concern. Bachman's sparrow is under review for listing. Fish and wildlife views both the red cockaded woodpecker and the Florida panther as endangered, while Game and Fish views the latter as endangered but the former as threatened only. Aquatic or Wetland Dependent An "aquatic and wetland dependent" species is a species that "requires wetlands or aquatic systems to satisfy some critical biological need in its natural life cycle," (T. 524) apart from simply drinking water. "[W]ithout wetlands or aquatic systems, these species would probably be extirpated from the state." Id. The Sherman's fox squirrel, the gopher tortoise, the Florida mouse, the Florida long-tailed weasel, the southeastern kestrel, and Bachman's sparrow are not aquatic or wetland dependent. Because they use watery environments for feeding, reproduction and other purposes, the alligator, the wood stork (the only stork in North America) and the gopher frog are aquatic and wetland dependent. Because "the whole black bear population in our state seems to shift . . . primarily in the fall and winter months, to the wetlands and . . . eat . . . fruit produced in wetland trees," (T. 527) the black bear is deemed wetland dependent. The indigo snake is also so classified because it "seemed to be heavily dependent upon eating frogs." (T. 526). Even though not wetland dependent "historically and naturally," (T. 527) the "less than probably 100 Florida panthers left in the state" are now so viewed because "they have more or less been restricted to the major swamp systems," id., without which they probably would not survive. The contiguous wetlands on site comprise the headwaters of Durbin Creek, which empties into Julington Creek shortly before Julington Creek reaches the St. Johns River. Large scale residential development of lands lying within the watershed of Durbin and Julington Creeks has been proposed. Durbin Creek and the swamp that gives rise to it serve as a "juvenile fish nursery" (T. 2468) for white shrimp, blue crabs, croaker, anchovies, bream, bass, shellfish, bluegill, and sheepshead. Lower dissolved oxygen levels or other stressors in Durbin Creek would decrease populations in fisheries already at carrying capacity, and already threatened by the prospect of overdevelopment. Dredging and Filling The City intends to build a road running east and west between the landfill site and U.S. Highway 1 following, for the most part, an existing dirt logging road, and crossing Old Kings Road, built in 1765 to connect the capital of colonial Georgia with St. Augustine. Turbidity screens and staked hay bales would be used during road construction to protect adjacent waters. After construction, seeding and mulching would stabilize the sloping shoulders of the fill road. In connection with construction of the access road, plans call for filling wetlands contiguous to Durbin Swamp, 2.8 acres within DER's jurisdiction and 3.5 acres within St. Johns River Water Management District's jurisdiction. Fetterbush, gallberry, scrub palmetto, cinnamon fern, bamboo vine and sphagnum moss grow in these contiguous wetlands, under a canopy of slash pine, loblolly bay, cypress and swamp tupelo. The proposed Class III disposal area would lie two hundred feet north of the south property boundary and 600 feet west of the east boundary. Over significant portions of this 88-acre site, fill dirt is to be used to raise the grade, because the land is so low. Enough fill is to be placed in the marshes and sloughs to avoid depositing solid waste in the water. Trucks would haul fill dirt to the eastern part of the site ("the area starting at the northeast corner of the Class III landfill and extending about 300 feet to the west, starting from a point about midway along the eastern margin of the landfill, and extending about 450 or 60 feet to the west, and along the southern portion of the Class III landfill, about . . . 600 feet" T. 1562) and elsewhere on site, smothering isolated wetlands, where more or less healthy vegetation, generally of the kind found in the contiguous wetlands, now grows. The 132-acre Class I disposal area, which would abut the Class III area on the north, would also cover isolated wetlands now on the site. Together with excavation of associated stormwater retention basins, the disposal areas would disturb a total of 46.3 acres of isolated wetlands within the St. Johns River Water Management District's jurisdiction. The St. Johns River Water Management District originally asserted jurisdiction over 48.5 acres of isolated wetlands, City's Exhibit No. 80, but the objectors offered no evidence that staff's subsequent decision that vegetation on one 2.3-acre parcel did not qualify was erroneous. This total does not include isolated wetlands less than half an acre in extent or isolated wetlands lying both within and without the disposal areas which will cease to function as such when truncated by dredging or filling. In this latter category are some ten acres that will not themselves be dredged or filled. T. 2777-8. St. Johns River Water Management District identified 5.3 acres of high quality isolated wetlands with connections off-site that are to be impacted, City's Exhibit No 80, along with another 11.2 acres of "low quality" isolated wetlands. Id. No stormwater retention basin would intrude into DER's jurisdictional wetlands, but approximately nine tenths of an acre falling within the St. Johns River Water Management District's contiguous wetlands boundary would be devoted to stormwater retention basins. Replacement Wetlands To mitigate the planned filling of contiguous wetlands for construction of the access road, the City proposes "to excavate 3.5 acres of nonjurisdictional pine plantation and create a contiguous swamp wetland." City's Exhibit No. 56. Mature dahoon holly, loblolly bay, cypress and gum trees "will be transplanted from on-site [isolated] wetlands proposed for construction impact." Id. A tree spade is to be used to transplant trees with trunks as much as 12 inches in diameter at "breast height" and up to 50 feet tall, along with existing soils, microbial communities and adjacent understory vegetation. The "physical structure of the trees themselves . . . provide a good deal of the habitat." T. 436. Removing mature trees from isolated wetlands and replanting them in created wetlands would, to some extent, mitigate the loss of perches for bald eagles and other birds. Mature trees in the created wetland would be replanted at a density "approximately half that of existing on-site wetlands to be impacted." Id. Only 80 percent of the replantings are to be replaced, if they die; and then only if it is clear within three years that replacement is needed. A six-inch layer of organic soil, to be spread after the trees have been transplanted, would "provide for growth of herbaceous vegetation." Id. The City would monitor the created wetland (part of mitigation area "A") for three years and transplant additional trees, if needed to assure survival of not less than 80 percent of the number of trees originally planted. Of these 3.5 acres, the City has identified 2.8 as specifically intended to mitigate the filling of wetlands within DER's jurisdiction. With respect at least to this portion, the created wetland "will function probably much the same as the 2.8 acres" (T. 2765) to be filled in constructing the access road and "would compensate for the" (T.2765) attendant loss of vegetation. In transplanting mature hardwoods, "[i]t's sort of a physical impossibility to get all the root material . . . [and y]ou also get some loss of branches, limbs and stems just from the physical movement of the tree." T. 2482-83. One reason a wetland "system stays wet . . . is a thick canopy." T.2486. With more sunlight streaming through a sparser canopy, the "vegetation is not going to be the same." T. 2487. "[B]ecause you don't expect the wetlands to function as well as the original wetlands you're replacing, there is a general rule of thumb that . . . you create twice as much wetlands as the wetlands you've destroyed." T. 2488. "A three-to-one ratio would not be unusual for a good mature forested hardwood system." T.467. St. Johns River Water Management District's Applicant's Handbook calls for a ratio between 2:1 and 5:1, but states: "The ratios may also be adjusted when wetlands creation is combined with wetland mitigation proposals such as an open buffer area adjacent to the wetlands, conservation easement, wetland enhancement proposals or alternative mitigation proposals." T. 504. The ratio proposed here is less than one to one. In all, mitigation area A would comprise 11.0 acres of what is now pine plantation. Aside from a .55 acre pond in the middle, mitigation area A would consist of wetlands contiguous to existing wetlands on which three different, if related, vegetative communities are to be planted. In addition, the City proposes to create three different isolated wetland areas, one of which (mitigation area D) it characterizes as "high quality." Six acres of what is now pine plantation would be excavated on the north edge of the property. Using the same, experimental techniques proposed for mitigation area A, cypress trees would be placed on 3.4 acres, and 2.6 acres would be devoted to a combination of loblolly, cypress and dahoon holly. Another 9.8 acres of isolated wetlands would be created within borrow pits, 6.8 acres in borrow area No. 1 (mitigation area B) which would include .55 acres of open water, and 3.0 acres in borrow area No. 2 (mitigation area E.) Just north and east of the truck scales, mitigation area B would receive 200 adult trees per acre planted to the extent they are available on site, or 400 trees per acre planted with nursery stock. The same density is planned for mitigation area E, to be located across the road from stormwater retention basin 4. The City also proposes to remove a segment of a logging road built on fill that now cuts off 40 acres from the remainder of Durbin Creek Swamp. Removal of the fill and revegetation would not only increase the extent of the swamp by 0.3 acres, it would restore historic sheet flow in that part of the swamp. Finally, the City proposes to spread muck, if available, over the shallow, southern part of stormwater retention basin 2 and plant 12 acres of grass ("[w]etland herbaceous species" City's Exhibit No. 80) which, however, the City reserves the right to dredge up "from time to time". Id. p.13. Other Effects, Other Mitigation Building and operating the landfill on the site proposed would displace upland wildlife and fragment largely undisturbed and undeveloped wildlife habitat. Fences along the northern, eastern and southern site boundaries would present a physical barrier. Human activity, particularly daytime traffic on the access road, would also create a "bio-geographical barrier." Developing a landfill at the edge of the swamp amounts to "leapfrogging," instead of expanding existing pockets of industrial or other development. A witness characterized the area to the south of the site as "rural developed"; some 164 people live within a mile of the center of the site. T. 78. But private ranch lands to the north, like undeveloped land to the east, afford good wildlife habitat. Habitat fragmentation divides and isolates animal populations. "Fragmented populations are more susceptible to disease, inbreeding and with time, poaching." T. 2890. The landfill would displace gopher tortoises, their commensals, if any, and other wildlife using sandhill or pine plantation habitat, as well as wildife, including wood storks and other migratory birds, making use of the isolated wetlands that are to be filled over. With the filling of isolated wetlands, migratory birds would lose holly berries and other forage. Filling or excavating acreage at the periphery of the swamp would also destroy habitat and displace wildlife. Wildlife now on site reaching suitable habitat elsewhere will have to compete for limited space against animals that have already established territories. The result should be a net decline in populations. T.2898. Increasingly sequestered, the Durbin Swamp system is already under pressure from urbanization to the north. For animals that remained in the vicinity, development of the landfill would occasion other difficulties. But evidence that landfill noises and odors "would have no discernible impacts to the value of wetlands as habitats for aquatic and wetland dependent species" (T. 528) went unrebutted. A buffer of at least 50 feet would separate contiguous wetlands from stormwater basins and other construction, but this is considerably less than the 528 feet Dr. Harris testified was necessary to avoid "greatly erod[ing] the native faunal diversity of the Durbin Swamp wildlife." T.3073-74. Placement of the landfill on this site would increase the numbers of a half dozen "middle-sized mammal omnivores" (T. 3078) so that gopher tortoises, turkey, quail, "anything that nests on the ground will be subject to the plundering by the enhanced population of raccoons, opossums, gray foxes, red foxes . . . and such." T. 3079. Increased numbers of armadillos would also pose a heightened threat to animals that nest on the ground. Landfill operations can be expected to attract seagulls and birds of other species, including nest predators and the brown-headed cowbird, which takes over other birds' nests to lay its own eggs (T. 3071-2) and would pose a particular threat to Swainson's warbler. It is not clear that any of the mitigation areas the City proposes is intended to replace wood stork feeding habitat that would be lost to dredging and filling. Wood storks feed on dense fish populations in shallow water, when receding water levels make the fish easier to catch. Isolated wetlands on site that have served this function would be lost (T. 2419), although not all of the isolated wetlands to be lost have enough water to support the kind of fish on which wood storks prey. The deep, steep-sided ponds planned for the mitigation areas do not replicate the necessary conditions. Whether birds may safely feed in or drink from untreated stormwater run-off in shallow portions of the retention basins is doubtful. When it rains, particularly the initial flush of run-off would deliver pollutants, including oil, greases and gasoline left by garbage trucks, to the retention basins. T. 1820-1. Removing the fill road and restoring normal flows to the 40-acre patch of the swamp on the other side, as the City proposes, would not add to feeding areas available to wood storks, except for the 0.3-acre roadway itself. The project would disrupt "very superior black bear habitat." T. 3059. Tending to avoid human activity, bears would likely range further east, foregoing foodgathering on site. On the other hand, food or other refuse brought to the landfill might lure bears to their deaths, intentional or accidental. "[C]ollisions with human vehicles," (T. 3062) is the chief cause of black bear mortality in Florida. Bears have been killed in this fashion within a mile of the site, (T. 351 1411-4, 2438) although not during daylight hours when the landfill would be in operation and garbage trucks would travel the access road. Creation of wetlands will not mitigate destruction of upland habitat. On the contrary, additional upland would be taken to create the wetland mitigation areas planned. But the City proposes to give a conservation easement on 129 acres of upland, adjacent to the swamp, that is to remain undeveloped. The upland easement would preclude a host of uses inimical to wildlife, and would mitigate to some extent the loss of wetland habitat for animals which use both uplands and wetlands, like the black bear, even though cut over slash pine plantation is among the very least important or productive wildlife habitats in Florida. The easement would not include sandhill habitat. The City has also undertaken to give a conservation easement covering some 260 acres of wetlands contiguous with Durbin Creek Swamp. This would not, of course, increase the extent of existing wetlands, but it would add a measure of protection for those that survived the project. Perhaps most importantly the wetland conservation easement would preclude expansion of the landfill further into the wetlands, as long as it remained in force. Existing regulatory restrictions on the use of wetlands prevent many uses, even without an easement. Apparently no regulation precludes harvesting bottomland hardwoods, however, so long as no excavation is involved, and vegetation, once severed, is not redeposited on site. But converting deforested areas to pinelands, without a permit from the Army Corps of Engineers would probably not be authorized, under 33 U.S.C. s.1344 (f)(2). See Avoyelles Sportmen's League, Inc. v. Marsh, 715 F.2d 897 (5th Cir. 1983). The City proposes to relocate gopher tortoises and any indigo snakes, gopher frogs or Florida mice that can be found to an unspecified new home off- site. Survival rates for gopher tortoises after similar relocations in the past have ranged between 30 and 100 per cent. By the year 2,000, the St. Johns County gopher tortoise population is predicted to fall by 90 percent, and Duval County is predicted to be devoid of gopher tortoises, even without relocation efforts of the kind proposed. Some or all of the gopher tortoises slated for removal may be descended from those who were brought to the site from Lake City. Perhaps even some who started out in Lake City would themselves make this second exodus to a new promised land. Stormwater Management The site proposed for the southeast landfill does not lie within a basin for which the St. Johns River Water Management District has adopted volumetric requirements. A "set of double [triple (T.1740)] box culverts five feet by eight feet . . . and . . . four other," (T. 425-6), "equalizer culverts," large enough for bears to move through (T. 415) would convey preexisting surface flows. A cross drain in the vicinity of the service plaza would serve the same function. Flood elevations would not increase more than a foot immediately upstream or more than 0.1 feet 500 feet upstream. The access road would not impound surface waters. Exfiltration trenches paralleling the access road "designed based on South Florida's criteria" (T. 1737) would filter contaminants from water running off the road. Within 72 hours of a 24-hour, 25-year return storm, the exfiltration system would be able to treat twice the volume of stormwater that recurrence of such a storm would generate. T. 1743. The scale plaza area where garbage trucks moving east on the access road would be weighed before being directed further down the road to a disposal area, is to be built on an upland portion of the property, and with it a wet detention pond to which surface water from the plaza and associated roadway would drain. Swales and berms would divert surface flow from undeveloped parts of the property that might otherwise reach the detention pond. The interceptor ditch and associated works would reduce by 2.5 hours the time of concentration for runoff from a 202-acre watershed, but cause no other changes in watershed characteristics. A weir would make it possible to regulate overflows and allow detention of run off long enough for biological assimilation of most pollutants. For the 25 year return, 24-hour storm, the pre-development peak rate of discharge (6.3 cubic feet per second) is less than the post-development peak rate without detention (18.4 cubic feet per second) but more than the post- development peak rate of discharge with detention: 3.9 cubic feet per second. An orifice below the weir, with a diameter of 1.5 inches, is designed to discharge less than half the treatment volume (22,088 cubic feet or 2.5 inches times the impervious portion of the area drained) in 64.21 hours. The design meets DER and St. Johns River Water Management District criteria. Portions of stormwater retention basins 1 and 2, situated north of the disposal areas, would lie within the 100-year flood plain. These two retention basins are designed to receive stormwater running off the Class I site or diverted around the site, as is stormwater retention basin 3, while stormwater retention basin 4 is intended to collect stormwater flowing off or around the Class III disposal area. Stormwater retention basins 3 and 4, like the southern area of stormwater retention basin 2, are not to be excavated to a depth of more than five feet below grade, to prevent groundwater from seeping into stormwater retention basins, dewatering the wetlands where it would otherwise emerge. With terraces at 20-foot intervals, to a height of 60 feet above grade for the Class I site and 40 feet above grade for the Class III site, both landfills would resemble Mayan temples, at build out. Ditches around the perimeter of each terrace are designed to convey stormwater to slope drains which would bear water to the level below, eventually to the perimeter ditch on grade, from which it would flow, through box culverts under roads built around the landfill, into the retention ponds. To the extent necessary to prevent groundwater infiltration, the ditches are to be lined. Stormwater retention basin 2 has two discharge structures, while each other basin has a single discharge structure leading to a ditch that would convey stormwater to Durbin Swamp. Perforated pipes, swathed in filter cloth, would be buried under highly permeable sand, along the sides of the retention ponds. Installed above seasonal low groundwater elevations, in order to avoid draining groundwater from the area around the ponds, during dry seasons, (T. 1781) they would have to go below seasonal high groundwater elevations, in order to be low enough to serve as drains for the retention ponds. Ambient groundwater would seep into the pipes, whenever groundwater levels outside the ponds rose above the pipes' elevation. But the pipes would still be able to drain the retention ponds, because of the relatively greater (vis-a-vis soils on site) hydraulic conductivity of the highly permeable sand to be trucked in for use as a filter medium. In time, these side drains or underdrains would clog and require expensive maintenance. But, assuming proper maintenance of the retention pond drains and of the drains that make up the roadway exfiltration system, the landfill and associated development would not flood or dewater wetlands that are not themselves to be dredged or filled. Except what is lost to evaporation, water entering the retention ponds would reach the wetlands, whether through the underdrains, over the weirs and through the conveyance ditches, or by movement underground after seeping through the bottom of the basin. The post-development peak rate of discharge from the area draining into the stormwater retention basins should not exceed pre-development rates for a 24-hour 100 year return storm or any lesser event. Because of roads and other impervious surfaces, a greater volume of surface water should reach the wetlands, causing stages about two inches higher than under pre-development conditions in "a typical summer thunderstorm." T.1782-3. The increase in surface flow corresponds to a decrease in water percolating down into the groundwater, and may result in additional loss to evaporation of water that would otherwise reach wetlands. But any such effect will be slight; surface and groundwater levels and surface water flows will not be adversely affected. T. 1783. Nor will existing surface water storage capabilities be adversely affected, despite the placement of portions of retention basins 1 and 2 within the 100-year flood plain. This encroachment at the very edge of the flood plain would rarely have any effect on surface water flows. Almost all development is to occur outside the ten-year flood plain. The stormwater basins could hold an inch of runoff without discharging water over the weirs. The underdrains, which would, when originally installed, have a hydraulic conductivity of about 130 feet per day, could remove an inch of run-off within approximately 40 hours. On the conservative assumptions that half of a two-foot vadose zone would already be saturated at the time a 24-hour, 25-year return storm dropped an additional 8.9 inches of rain on site, and that soils on site have a porosity of .5, the retention ponds could contain the resultant run-off for treatment, before discharging it first through weirs then through the underdrains. Three surface water monitoring stations are planned. One upstream would make it possible to assess background conditions. Another at the point of discharge from stormwater retention pond 2 would reveal whether the retention ponds and their sidedrains were functioning as intended. A third monitoring station in the southwest corner of the site should give similar information as to the roadside exfiltration system. Hydrogeology Except in the southeastern corner of the City's property, where the ground slopes down to the east, the land the City owns, like the adjacent land to the south owned by the McCormicks, slopes down in a more or less northwesterly direction, falling from 55 feet NGVD on the southern boundary to 15 feet NGVD at the northwest boundary, which intersects an elbow of the swamp. Although groundwater flows east of north under the southeast corner of the property, the flow under the property is generally northwesterly, following the topography. Class II groundwater in the surficial aquifer underlies the property at depths ranging "from almost to land surface to five or 10 feet below." (T. 1517). City's Exhibit No. 161. Groundwater flowing northwesterly crops out in isolated wetlands, evaporates, transpires or discharges into the swamp. To assure that the bottom of each exceeds seasonal high groundwater levels, measured in February of 1987, by the number of inches a 24-hour 25-year return storm would add, fill would be placed under both disposal areas, as needed. Because the Class I solid waste disposal site is to be lined, recharge by rainfall would be precluded there. With a liner intercepting percolating rainwater, groundwater would not attain predevelopment levels. The depression thus induced under the Class I site would more than offset the tendency groundwater under the Class III site would otherwise have to mound up into the bottom layers of solid waste deposited there. Recharge from rainfall (become leachate) would continue at the unlined Class III site; the height of accumulated waste would slow or stop evapotranspiration offsetting percolation there. But groundwater would flow down steeper gradients to lower levels underneath the Class I site (which lies between the Class III site and the wetlands where groundwater discharges) rather than rising into waste disposed of on the Class III site. The horizontal component of flow would continue to exceed the vertical component by several orders of magnitude. Beneath the surficial aquifer, which extends to depths of 50 to 100 feet below ground and consists of sand interspersed with a "matrix of soil, organic materials, clays and silts . . . little layers of clay and hardpan" (T. 1517) lies a continuous, confining layer of gray, sandy material with gravel and shell fragments, 12 to 40 feet thick, blanketing the undulating surface of the Hawthorne formation underneath. "[S]ome 40 percent of the material comprising the Hawthorne formation in this area is clay and the remainder is a mix of sands, silt stone, shell beds and phosphatic sands." (T. 1526) This assures that rainfall or other fluids percolating into the surficial aquifer on site will move horizontally downgradiant, reentering the atmosphere or discharging to the surface, rather than penetrating the thinner aquitard above the Hawthorne formation and sinking another 250 feet or more through the Hawthorne formation itself into the Ocala group and Floridan aquifer below. No subterranean feature in the vicinity permits water in the surficial aquifer to reach the Floridan. No peat, muck or other unstable soils underlie the site. Under 3,000 pounds per square inch, the maximum load anticipated, the ground is not expected to settle more than one inch. The addition of fill dirt does not alter this estimate significantly. Disposal Design The Class III disposal area would not have a liner, a leachate collection system or gas controls. After travelling through soils under the site, leachate from the Class III site would enter the groundwater. The City proposes to train and direct staff, to the end that only yard trash and construction and demolition debris end up in the Class III disposal area, where waste would be deposited directly on fill dirt or naturally occurring soils. No solid waste is to be disposed of within 200 feet of wetlands contiguous to Durbin Swamp lying within DER's jurisdiction. A composite liner of the kind in place at Alachua County's southeast landfill would form the corrugated bottom of the Class I landfill: a 60 mil high density polyethelene layer overlying two six-inch lifts of calcium montmorillonite, a clayey sand that is to be placed on compacted subgrade configured in "a herringbone design with peaks and valleys." T.765 Separating trenches in the valleys, sloping ground would rise, then fall at least two feet for every hundred horizontal feet. Steps would be taken to remove rocks, twigs, roots and the like, before compacting subsoils on site. A machine called a sheepsfoot is to be deployed, once half the montmorillonite has been put down, to pulverize clods and mix the material, in an attempt to assure uniformity within each lift of clayey sand. Other machines would compact each lift to a specified Proctor density. These efforts would not succeed in eliminating all clods or other imperfections, and the sheepsfoot would mix subgrade with the bottom layer of montmorillonite, introducing new impurities. Soils on site have hydraulic conductivity ranging from 1 x 10-3 to 1 x 10-4 centimeters per second. Clayey sand is also subject to desiccation cracking; as it dries out, large cracks appear. On top of this kneaded, compacted and finished 12-inch layer of clayey sand, once it had been inspected to assure the absence of roots, rocks, sticks, glass or other sharp objects, a specialty contractor would unroll strips of unreinforced high density polyethylene. After arranging the panels to minimize seams in the leachate collection trenches, technicians would weld the polyethylene strips to one another. An independent, third-party quality assurance contractor would inspect and test the seams before the synthetic liner was finally positioned, and as flush a fit as possible was achieved. Both the high density polyethylene and the quality assurance program are to meet the requirements of NSF Standard 54 and EPA Publication SW-870, March, 1983. Some wrinkling and occasional flaws in the plastic liner are inevitable. Wrinkling causes ponding, not only of rainwater during construction, but also of leachate, once the landfill is in operation. Tire tracks or other indentations in the montmorillonite layer can also cause ponding. In time, under the growing weight of solid waste, and with heat that biodegradation of the waste would generate, some of the wrinkles might subside, but the liner might also sink into additional depressions. Careful construction could keep ponding to a depth of little more than an inch. T. 2971, 2979. Extrusion welds (when done properly) render the seams stronger than the panels they join. But even if "you are really, really good" (T. 2957) and even when you're careful you get an occasional problem, one or two per acre, no matter how careful you are. And if you're not as careful, you get more, typically something on the order of five holes per acre. T. 2967 Carelessness on one project resulted in as many as 60 flaws per acre. Nondestructive testing methods do not detect all defective welds. T. 2966. Defects may develop after the plastic liner has been inspected. Stress on high density polyethylene associated with "conform[ing] itself to whatever is underneath it" (T. 2962) concentrates in scratches, gouges and crimps to cause "as much as 30 percent" (T. 2964) of the holes in the material. "[T]here is no shortage of scratches on a construction site." T. 2962. Leachate Collection Another high density polyethylene geotextile, chosen for its transmissivity (the geonet), is to be placed on top of the high density polyethylene liner (the geomembrane), where it would act as a synthetic drainage medium. In order to prevent overlying sand's clogging the geonet, compromising its ability to conduct leachate down into the trenches, a third, highly permeable geotextile, "a non-woven needle punched type" (T. 637) (the geofilter) would go directly on top of the geonet. The twelve-inch sand drainage layer blanketing the geofilter would have hydraulic conductivity of 1 x 10-3 centimeters per second, if sufficient quantities of suitable sand could be obtained. (T. 764) Another 12 inches of native soil is to cover the sand drainage layer. While the geofilter and the soil layers above it would parallel the landfill liner on the slopes between trenches, they would form arches over the trenches themselves. Continuing to follow the contours of the montmorillonite, the geomembrane and the geonet would line the trench bottoms. Below these arches, inert drain field rock would fill the lined trenches, supporting one perforated PVC pipe eight inches in diameter in each trench. The Class I landfill is to be built in fourteen 250-foot wide cells, with each cell having two leachate collection pipes on 125-foot centers. Manholes at either end of each leachate collection pipe would allow access, in case unclogging the pipe proved necessary. Longitudinally, the trenches would slope to the north, falling two to 20 feet for every 1,000 horizontal feet. Leachate reaching the trenches would flow along the trench bottoms (or through the pipes) to the manholes on the northern boundary. Also to be made of leachate-impervious PVC, leachate drain pipes, which would not be perforated, would connect all manholes on the northern perimeter. Varying in diameter from eight to twenty inches, depending on the number of manholes they were designed to empty, they would converge at a leachate pumping station north of the perimeter road. T. 590-1. A rupture in one of the single-walled leachate drain pipes could spill massive quantities of leachate on naturally occurring soils. Leachate which reaches the station is to be pumped into a 12,000 gallon storage tank nearby. To be mounted on a concrete slab surrounded by a curb high enough to contain all 12,000 gallons, if the tank failed, the tank would be constructed of high density polyethylene. The plan is to pump leachate from the tank through a four-inch discharge pipe into tanker trucks which would take the leachate to the Buckman wastewater treatment plan for disposal there. During "the maximum leachate production period, when you have 10 cells open," (T.687) an average of 35,000 gallons of leachate a day would require removal for disposal in this fashion. Additional tanks could be built. As a precaution, isolation valves would permit cutting off all flow of leachate to the pump station. In addition, isolation valves would allow cutting off the flow from any of seven pairs of cells (or slowing the flow from all, T. 705) in the event of an abnormal circumstance where leachate production in the facility exceeds the hydraulic capacity of [the] leachate removal system, the pumping station and storage tank and the tanker truck system. T. 591. Isolation berms separate each pair of cells susceptible to being put to use as temporary storage for leachate. The leachate drain pipes themselves afford more than 23,000 gallons of emergency storage. T.703. Ventilation As they decompose, materials to be deposited in the Class I landfill produce methane gas, carbon dioxide, and other, malodorous gases. Collection pipes with eight-inch diameters, running horizontally on 150-foot centers in the second and fifth lifts would allow gas to escape at either end, on the north and south sides of the landfill. This would prevent methane's building up and exploding or catching fire. By assuring their gradual release, it should also minimize the impact of foul smelling gases, which, in any event, are generally undetectable at a distance of more than 1,000 feet. But specific condition eight of the proposed landfill permit requires that the passive system be converted to an active system, if necessary, using vacuum suction and flaring. GIGO Although there "is not much industry in the southeast portion of Duval County," (T. 953) sewage sludges and other industrial wastes "except any hazardous waste as defined in the Federal Register" (T. 947) would be accepted for disposal at the Class I facility, if properly manifested. The proposed southeast landfill would receive waste that would otherwise have gone to the unlined east landfill. Household waste contains toxic materials. Tests of leachate generated in other lined landfills from which hazardous wastes are excluded have demonstrated the presence of some 30 metals and 56 organic compounds. City's Exhibit No. 89. Rainfall percolating through (and moisture already present in) waste deposited at the proposed Class I facility can be expected to leach the same array of substances from materials deposited there. Judging from experience elsewhere, leachate from the Class I facility would contain 13 or 14 (if 4-methyl phenol is included) substances in concentrations in excess of governmental standards or health-based criteria identified by a toxicologist engaged by the City. City's Exhibit No. 90. Among these would be methylene chloride, trichloroethylene, tetrachloroethylene and benzene, (T. 1478) as to which "the current regulatory policy is that it is possible for as little as one molecule . . . to act as . . . a carcinogenic initiator . . . [so] that there is no real threshold." T. 1447. Maximum concentrations would exceed those Florida prescribes as primary drinking water standards for titanium threefold, for benzene fivefold, for chromium more than fivefold, for sodium approximately 16-fold, for manganese 68- fold, for iron 280-fold, and for methyl ethyl ketone almost 130-fold. City's Exhibit No. 90. Methylene chloride would occur in the leachate in concentrations 39 times greater than the "USEPA proposed Preliminary Protective Concentration Limits." Id. Only yard trash "soils/land clearing waste, waste from landscapers" (T.956) and construction and demolition debris, "clean debris, inert materials, construction and demolition wastes that are inert, roofing materials," id., and the like, not mixed either with industrial or with regular household garbage, would be accepted for disposal in the Class III facility. Unless these materials are adulterated, they are "easy to bio-degrade . . . [or] are insoluble," (T. 1923) and rainwater percolating through them should yield a leachate with "neutral pH . . . low to moderate [biological oxygen demand] . . . [and] metals [if any] . . . below detection limits or background conditions." T.1923. But "some materials get in" (T. 2106) despite efforts to exclude them. "Demolition debris can have oiled floors and creosoted pilings as part and parcel of the structure." T. 3008. Old paint contains lead and cadmium. Debris from old houses can include rat poisons. Grass clippings "could contain small amounts of herbicides and pesticides." T.2101. In fact, "it's not unusual for yard waste to be very rich in biocides." T. 3009. Such chemicals are used in Jacksonville. When autopsies of seagulls found at the Girvin Road landfill revealed traces of diazanon, tests of water taken from "the stormwater ponds in the subdivision across the street" (T.990) showed diazanon was present there. Bioassays the DER runs on effluent from the City's Buckman wastewater treatment plant regularly report toxicity in excess of allowable limits (T.1877-8) and the EPA has "identified malathion and diazanon as the toxicants," (T. 1881) which are killing at least one species of flea in certain standard laboratory tests performed on the effluent. Leachate Leakage The composite liner would not keep all leachate generated in the Class I landfill from reaching the naturally occurring soils underneath, and eventually the groundwater under the site. Even under normal operating conditions, and even on the City's optimistic assumption that it can achieve a permeability of 1 x 10-7 centimeters per second, thousands of gallons of leachate a year would escape through flaws in the liner while the landfill was in operation. If leachate drain pipes burst or torrential rains required backing leachate up in the cells, thousands of gallons a day could leak. If two lifts of clayey sand achieve a permeability no lower than 1 x 10-5 centimeters per second, millions of gallons of leachate would enter the groundwater over the ten-year active life of the landfill, even without burst pipes or extraordinary precipitation. Once the Class I landfill attained the design height, it would be capped with impermeable materials to minimize leachate generation. As with the liner underneath, the impermeable cap would be covered with sand to facilitate drainage. Vegetation would hold the drainage soil in place. Closure plans have already been drawn, but they are subject to revision and require DER approval before implementation. If necessary, side slopes could be lined to prevent leachate seepage there. Closure would reduce, but would not end, leachate production and leakage. Virtually impermeable to water, high density polyethylene is highly permeable to certain permeants, including some that occur in landfill leachate. Leachate constituents known as "aromatic hydrocarbons" move "right on through" (T. 3017) high density polyethylene. To some extent, the montmorillonite component of the liner under the Class I area would impede these materials' movement into naturally occurring soils. The evidence did not quantify the montmorillonite's efficacy in this regard, but the City's expert's testimony that leakage of this kind would be "insignificant" (T. 830) went unrebutted. Permeation aside, the rate at which leachate leaks depends on the nature, number and size of flaws in the synthetic liner, the height and duration of the leachate head above the defects, and the transmissivity of what is underneath. Here transmissivity turns both on the hydraulic conductivity of the clayey sand in the vicinity and on the extent of air spaces between the clayey sand and the overlying high density polyethylene. Sand grains cause microscopic spaces, while imperfections in the montmorillonite layer and wrinkling of the polyethylene cause larger spaces. Leachate leaking into a space between the geomembrane and the soil spreads over a larger area before penetrating the clayey soil, in correspondingly larger volumes. Calculations predicated on the transmissivity characteristics of the geonet and the sand layer above it demonstrate a theoretical leachate flow over the liner so rapid that leachate would never accumulate on the geomembrane to a depth of as much as a tenth of an inch. But these calculations assume no ponding behind wrinkles in the synthetic liner, or any other impediment to the flow of leachate. Especially since holes in liners are likely to occur near wrinkles (because stresses are greater there) a more realistic assumption, for calculating leachate leakage rates, is a head of one inch, "the smallest practical hydraulic head you can achieve." T. 2994. On the twelfth day of hearing, when St. Johns County's liner expert testified that a six-inch layer of the montmorillonite might result in permeability as high as 5 x 10-4 centimeters per second, the City had not yet amended its application to increase the thickness of the clayey sand layer from six inches to twelve. The City's proposal now calls for two lifts of a 20 percent clayey sand with a saturated hydraulic conductivity in situ of 1 x 10-7 centimeters per second. This can be achieved, if at all, only with material that laboratory tests indicate has hydraulic conductivity of 1 x 10-9 centimeters per second or less. "[I]f you put down clay that the lab says has a permeability of 10 to the minus 7 centimeters per second, . . . when you put it down in the field you get from one to two orders of magnitude greater permeability than that. . . . related to how thick it is." T. 2988. Even a three-foot liner comprised of six lifts ends up with conductivity ten times greater than the same material under laboratory conditions. Mr. Deans, who designed the liner for the City, testified that a permeability of 1 x 10-7 centimeters per second was "readily achievable" even with six inches of clayey sand, but he had never designed a liner before, and his testimony in this regard has not been credited. To judge from its eleventh- hour amendment, the City did not believe it, either. Only two lifts are to comprise the clayey sand layer. No study of a clayey sand layer as thin as 12 inches has found hydraulic conductivity of less than 1 x 10-5 centimeters per second. Three lifts are necessary to create an effective barrier. "[Y]ou need at least three lifts to get the middle one hopefully working right." T. 2987. "[E]ngineers believe that the bottom layer gets fouled, the top layer cracks and has problems. Your best chance is the in between layers. You need at least three layers, and they would rather have four to be reasonable, and EPA says six." Id. Studies of twelve-inch liners put down in two lifts ("[t]he thinnest one we found anybody had ever studied" T. 2980) showed them to be "inadequate." T. 2987. With an inch of head, assuming defects with an average area of 1 x 10-5 square meters, an assumption with which all the experts seemed comfortable (the City's expert assumed larger holes), the published EPA formula yields a per defect leakage rate of 6.7598 x 10-11 cubic meters per second, assuming hydraulic conductivity for the montmorillonite layer of 1 x 10-7 centimeters per second. But plans to use only two lifts to form a 12-inch layer do not give reasonable assurance of vertical hydraulic conductivity that low. Mr. Coram's testimony to the contrary, expressly predicated on reports of laboratory tests on samples, did not address the evidence that laboratory tests do not tell the whole story, in the case of a thin layer of clayey sand compromised not only by inherent imperfections, but also by highly permeable subgrade soils, kneaded into it by the sheepsfoot. Because "clods are broken down in the laboratory and stones and cobbles are screened from the sample . . . the effects of both are not accounted for in permeability tests on laboratory compacted samples." City's Exhibit No. 190. Substituting a hydraulic conductivity of 1 x 10-5 centimeters per second, the EPA formula yields a leakage rate between 57 and 58 times greater: 3.8898 x 10-9 cubic meters per second. Although the EPA's most recently published leak rate formula makes no allowance for less than an ideal fit between the components of a composite liner, City's Exhibit No. 190, the author of the EPA formula, who testified for St. Johns County, subscribed to modifications to the formula developed to take this factor into account. DER's Exhibit No. 35. The montmorillonite layer's hydraulic conductivity is an unrealistically low measure of the transmissivity of the medium underneath the polyethylene. Using it for this purpose, without adjustment, ignores inevitable, intervening air spaces. Perfect contact between a synthetic liner and the soil it overlies cannot be accomplished, even in a laboratory setting. On a project of the kind proposed, contact would range from good, where the relatively larger size of sand grains in the clayey mix creates air spaces, to poor, where wrinkles (left in to avoid the weakening effects of stretching the material) cause much larger air spaces. No expert found fault with the more recent formulae (Bonaparte/Giroud) set out in DER's Exhibit No. 35, and none quarreled with the proposition that the published EPA formula made unrealistic assumptions about the contact between polyethylene and clayey sand. The Bonaparte/Giroud formula that assumes good contact yields a leakage rate of 1.6090 x 10-8 cubic meters per second per defect, a little more than four times what the EPA formula predicts for an ideal fit, assuming an inch of head and vertical hydraulic conductivity for montmorillonite in situ of 1 x 10-5 centimeters per second. Assuming poor contact, without varying any other assumptions, yields a leakage rate approximately 5.5 times greater: 8.8115 x 10-8 cubic meters per second. In its proposed recommended order, at page 35, DER accepts, at least for purposes of argument, the proposition that contact between soil and geomembrane would be poor in places, and calculates a leachate leakage rate of 5.45 x 10-3 gallons per day (2.3887 x 10-10 cubic meters per second per defect.) But this assumes that "the permeability of the City's clay liner will be 1 x 10- 7 cm per second and the maximum head over liner will be 0.062 inches." The evidence showed that the maximum head could not be kept below one inch, and did not give reasonable assurances that two lifts would result in vertical hydraulic conductivity of 1 x 10-7 centimeters per second for the clayey layer. Substituting an inch for .062 inches gives a rate of 2.9177 x 10-9 cubic meters per second. Substituting 1 x 10-6 for 1 x 10-7 and an inch for 0.062 inches, the leakage rate becomes 1.6034 x 10-8 cubic meters per second. Groundwater Contamination Uncontroverted expert opinion put the flow of groundwater under the Class I disposal area at 0.063 cubic feet or 0.47 gallons per day (2.0592 x 10-8 cubic meters per second) through a hypothetical square or cube one foot on a side. Except under unusual conditions, leachate leaking from the Class I facility would, before entering the groundwater, pass through approximately a foot of fill dirt or naturally occurring soils, which consist in large part (92 to 99 percent) of relatively inert, quartz sand. The presence of organic materials, however small the quantities, raises the prospect of adsorption and other chemical reactions, before steady state is attained. Physically, the soil would disperse the leachate, diminishing concentrations of leachate constituents entering groundwater. After such attenuation as the soil afforded, leachate would enter the groundwater, which would dilute and further disperse it, although not nearly as dramatically as the City's toxicologist testified. This witness assumed uniform mixing, rather than the discrete plume which persons with greater expertise in groundwater contamination convincingly predicted. By using the rate of "groundwater flow beneath a defect and the rate of leakage through that defect . . . [he] c[a]me up with a volume to volume dilution factor to identify a concentration in the groundwater." T. 1214. Because Dr. Jones took an unrealistically low leakage rate as a starting point, he predicted an unrealistically low concentration of one part leachate to 4,400 parts groundwater, inside a cubic foot immediately below each leak. Concentrations vary directly with the leakage rate per defect. T. 1224. The formula that assumes good, but not ideal, contact between liner components yields a leakage rate per defect of 1.609 x 10-8 cubic meters per second, if the layer of clayey sand has hydraulic conductivity of 1 x 10-5 centimeters per second. Substituting this leakage rate, the City witness' methodology yields a dilution ratio of 2.0592 parts groundwater to 1.609 parts leachate, or 1.2798:1, more than a hundred times less than the 130:1 dilution ratio that the City concedes is the minimum it must prove, at the edge of the zone of discharge. See Respondent City of Jacksonville's Motion to Strike St. Johns County's Memorandum Concerning Leachate Rates, p. 5. Substituting the coefficient for poor contact, the ratio in the hypothetical cube under the landfill becomes a paltry 2.0592 parts groundwater to 8.8115 parts leachate or .2337:1. Using Dr. Jones' methodology, a leakage rate of 1.6034 x 10-8 cubic meters per second per defect would result in leachate concentrations in groundwater of one part leachate to 1.2483 parts groundwater. Substituting a rate of 2.9177 x 10-9 cubic meters per second per defect yields a ratio of 2.0592 parts groundwater to .29177 parts leachate, or one part leachate to 7.0576 parts ground water. Even if the contact between geomembrane and montmorillonite were uniformly good and the clayey sand layer had a permeability of 1 x 10-7 centimeters per second at every point, a dilution ratio of only 37.4444:1 would result. In 132 acres of high density polyethylene, the evidence showed that 660 flaws could reasonably be anticipated, and that 132 flaws were absolutely unavoidable. Methylene chloride would end up in the groundwater in proscribed, carcinogenic concentrations as far away as 20 feet from many leaks within 90 days. Under some leaks, perhaps all, benzene, a proven human carcinogen, would also occur in prohibited concentrations. As leachate plumes dispersed, concentrations would diminish, eventually to levels at which they pose "potentially acceptable" (T. 1475) risks even in the case of "a 70-year water consumption of two liters of water per day by a 70-kilogram adult." T. 1217. No evidence suggested that they would remain in concentrations above these levels by the time they reached the edge of the zone of discharge. City's Exhibit No. 193, which uses a leakage rate much lower than the range of leakage rates likely to occur, if the landfill is built, predicts concentrations of various leachate constituents at the edge of the zone of discharge, assuming a leak at the edge of the disposal area. Multiplying predicted concentrations by quotients, obtained dividing likely leakage rates by the assumed rate, suggests carcinogenic leachate constituents would not occur in prohibited concentrations at the edge of the zone of discharge. But extrapolating in this fashion also suggests that violations may occur outside the zone of discharge, absent attenuation in the vadose zone, in the event of a leak at the edge of the Class I disposal area, for iron, manganese and methyl ethyl ketone. Groundwater Monitoring The City proposes to place monitoring wells at intervals of 250 to 500 feet around the Class I and Class III disposal sites. Some 25 shallow monitoring wells would be located 50 to 100 feet from the deposition areas, within the zone of discharge. In addition, seven clusters, each consisting of three wells screened at different depths, would punctuate the boundary of the zone of discharge. A cluster of wells upgradient would make it possible to monitor background conditions. With two-inch diameters and ten-foot screens, each well would receive a flow of less than a gallon a day. The contaminant plume from the Class III landfill would be large enough to be detected readily in samples drawn from a number of wells. But there was testimony that the plume, even from a 10-foot wide leak at the edge of the Class I disposal area, could pass between two wells 500 feet apart, undetected. Rather than a single large leak, moreover, the experts predict hundreds of small leaks in the Class I disposal area liner. The assumption is that flaws in the geomembrane would have an area of only one tenth of a square centimeter, on average. Any one of the plumes emanating from such a leak could easily pass undetected through a 500-foot gap between monitoring wells. The monitoring plan apparently relies on the great number of leaks expected. But even if samples from a monitoring well revealed a leak, the magnitude of hundreds of other leaks would not be disclosed. Well Contrived After the City filed its application for a permit to construct a landfill, but before DER had issued its notice of intent to grant the application, four wells were put in on the McCormick property, within three feet of the southern boundary of the City's property, and within 205 feet of the proposed Class III disposal area. The wells are more than 500 feet from the lined, Class I disposal area. Spaced at 1,000-foot intervals, within a 125- foot-wide utility easement in favor of the City of Jacksonville Beach, three of the wells are 25 feet deep and one is 28 feet deep. McCormicks' Exhibit No. 7. Each consists of a length of PVC pipe, 1 1/4" in diameter, leading to a red pitcher pump mounted on a wooden platform supported by four fence posts. City's Exhibit No. 194. Pumps of this kind must "periodically be pumped and primed or they have to periodically be taken apart and have the internal seals and leather valves replaced." T.2005. On April 7, 1988, the St. Johns River Water Management District issued a warning notice to "Haden McCormick" alleging that the wells had not been grouted, had been dug without necessary permits, and had not been the subject of required well completion reports. The next day, the St. Johns County Environmental Protection Board, apparently in response to applications inspired by the warning notice, issued a permit for each well designating the "usage" of each as irrigation. McCormicks' Exhibit No. 7. Well completion reports dated April 14, 1988, reported that the wells had been grouted. McCormicks' Exhibit No. 3. Asked the purpose of the wells in a deposition on April 25, 1988, J. T. McCormick said, "We need to monitor what [the landfill is] doing . . . [W]e need to . . . prepare ourselves for having people live in this area, to occupy it, to monitor it." T. 2227-8 A week earlier J. C. Williamson, Jr. had requested on behalf of B.B. McCormick and Sons, Inc. that the St. Johns County Environmental Protection Board amend the permits to show well usage as "Private Potable" instead of "Irrigation". This request was granted on April 27, 1988. McCormicks' Exhibit No. 2. On May 2, 1988, St. Johns River Water Management District's chief hydrologist wrote a lawyer for the McCormicks that "the completion reports submitted by a licensed driller, and the St. Johns County permits fulfill the requirements of the District." McCormicks' Exhibit No. 1. Analysis of samples of water taken from the wells on February 27 and 28, 1989, revealed total coliform levels acceptable for private wells. John Haydon McCormick explained the decision to put the wells in: [D]uring that week the City had filed their application with the DER which, in a sense, fixed their design . . . and when we became aware that this Class III landfill was as close as it is to our border, we became concerned about the future use of potable drinking water, and after consulting with counsel we were informed that we could legally install wells along that border. T. 2242. No owner of the property where the wells are located lives on the property nor, as far as the record shows, has an owner or anybody who does live on the property ever drunk water from the wells. About a half mile from the City's property are two other wells near a house on the McCormick property. When an owner's son drank water from one or more of the wells, as recently as the fall of 1988, he had to take water to the site with him in order to do it. The hand pumps require priming and nobody has bothered to store water near them for that purpose. On February 26, 1989, when the City's expert arrived for "splitting samples to submit to different laboratories," (T.1007) The "pumps were in a 20-gallon washtub in the back of . . . one of Mr. McCormick's employee's trucks. They were all removed from the well heads . . . [apparently] being soaked to generally recondition the seals in the pumps and to sanitize the pumps." T.2008 Two "of the old leather seals from the pumps [were] on the ground." T.2009. Within the shallow aquifer, groundwater flows from the wells northerly underneath the proposed Class III disposal area in the direction of Durbin Swamp. Use of the four existing wells "would in no way modify the groundwater flow system." T. 2045. But a well or wells could be so constructed on the McCormick property that continuously pumping from them would reverse some of the groundwater flow under the proposed Class III disposal area, to the extent that water flowing from beneath the Class III disposal area could be drawn from one of the existing wells along the McCormick boundary. T. 2075-80. Nor would consumptive use permits be necessary to dig wells which could cause such a change in groundwater flows. T. 2075. When the City discovered the wells abutting the southern boundary of its property, it did not direct its engineers to alter the design of the landfill to preclude solid waste disposal within 500 feet of the wells. The total project cost, excluding legal fees, is estimated in the neighborhood of $46,000,000. Redrawing the plans now to reduce the size of the Class III disposal area, without altering the size of the Class I disposal area, would take two to three months, and cost approximately $100,000. This approach would require reducing the capacity of the Class III area from 4.1 million cubic yards to 2.5 million cubic yards and, unless construction debris, which can be disposed of without a DER permit, were diverted elsewhere, its useful life from about ten years to about six years. Tipping fees would have to be higher "to recover the capital fixed costs over fewer tons." (T. 2208) Increased design costs alone would require recouping an additional 4 cents per cubic yard (more considering the time value of money) from tipping fees for Class III debris. Operations would be less efficient and presumably more expensive. T. 2207. Alternatively, the entire facility could be redesigned to achieve the same capacity and useful life as now contemplated. Such a redesign would require four to six months' work and cost approximately $250,000. Recovering this cost through increased tipping fees for Class III wastes would add slightly more than 6 cents a cubic yard (again ignoring the time value of money.) Alternative sites for disposal of Class III waste are available to the City. Indeed the site for which the City now seeks a permit was not even among the ten sites originally considered for the project. T. 2224-5. Decreased transportation costs to another site closer to the source of such waste might more than offset increased tipping fees. But separate facilities could create other problems. Ms. Nogas explained: From an operations standpoint . . .If I run out of Class III area and . . . site a separate Class III area somewhere else, if I had a truck coming to that facility and he really should have been in a Class I area, and I say "No, go out the gate and go five miles down the road . . .[to the] Class I facility," . . . I have a much better chance of . . . him never showing up at my Class I facility. T 2208-9. On the other hand, when asked about placing a Class III facility elsewhere in Duval County, Ms. Nogas, reiterating an earlier statement, testified, "[I]f that were what we had to go to, I would have no operational problems with it." T. 221. Mr. Wells' testimony that there "are 16,000 acres of less environmentally flawed acres seven to 12 miles from the generating centroid accessible from four-lane roads and not near residential or commercial properties," (T. 1248) and that the proposed site "is the furtherest site from the generating centroid, 21 and three-quarters miles to the dump site, and will cost taxpayers an extra $3 million to $5 million a year in longer haul time" (T. 1247) was received on the issue of the decisionmakers' credibility only.
Recommendation It is, accordingly, RECOMMENDED: That DER deny the City's request for variance. That DER deny the City's application for a permit to construct a landfill. That DER deny the City's application for a dredge and fill permit. That DER grant the City's application for a permit for management and storage of surface waters, on conditions proposed in the intent to issue, unless modified by agreement of all parties. DONE AND ENTERED this 16th day of October, 1989, in Tallahassee, Leon County, Florida. Robert T. Benton, II 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 16th day of October, 1989. APPENDIX A Petitioner St. Johns County's proposed findings of fact Nos. 1-4, 6, 10-12, 14, 16, 18, 21,23, 24-28, 33, 35, 37, 38, 41-45, 47-48, the first sentence of No. 51, Nos. 52-56, 57 except for the first sentence, which is rejected, 58, 59, 62, 64, 66, 68-74, 95-103, 106-109, 111- 116, 118, 131, 132, 133 except for subpart 7, 134, 136 and 137 have been adopted, in substance, insofar as material. With respect to petitioner St. Johns County's proposed finding of fact No. 5, and the second sentence of petitioner St. Johns County's proposed finding of fact No. 51, the design rate is not the same as the current rate of deposition. Petitioner St. Johns County's proposed findings of fact Nos. 7, 8, 9, 13, 15, 17, 22, 75, 110 and 138 relate to subordinate matters. Petitioner St. Johns County's proposed finding of fact No. 19 accurately recites the testimony. Petitioner St. Johns County's proposed finding of fact No. 20 is immaterial. With respect to petitioner St. Johns County's proposed finding of fact No. 29, the City's evidence that leakage of this kind was insignificant went unrebutted. Petitioner St. Johns County's proposed findings of fact Nos. 32 and 120-123 are immaterial to the present application. With respect to petitioner St. Johns County's proposed finding of fact No. 30, the City's estimates were unreasonably low. With respect to petitioner St. Johns County's proposed finding of fact No. 31, the evidence showed that nine gallons a day was at the upper limit, not that it would actually occur. With respect to petitioner St. Johns County's proposed finding of fact No. 34, at least 13 substances occur in concentrations that exceed health-based standards. Petitioner St. Johns County's proposed findings of fact Nos. 36 and 63, 117, 119 and 135 are proposed conclusions of law. With respect to petitioner St. Johns County's proposed finding of fact No. 39, the probability of a leak on the edge of the disposal area was not established. With respect to petitioner St. Johns County's proposed finding of fact No. 40, the evidence did not show that when "two or more toxic substances are combined" they necessarily have synergistic impacts. With respect to petitioner St. Johns County's proposed finding of fact No. 46, the City's assumption of no attenuation was an appropriately conservative approach that is not inconsistent with the City's unrefuted testimony that attenuation would occur. With respect to petitioner St. Johns County's proposed finding of fact No. 49, the evidence did not prove that the City would allow four feet of leachate to stand on the liner. Petitioner St. Johns County's proposed findings of fact Nos. 50 and 60 immaterial to the present application. With respect to petitioner St. Johns County's proposed finding of fact No. 61, the evidence did not establish the contentions following the clause ending "and into Durbin Creek,". With respect to petitioner St. Johns County's proposed findings of fact Nos. 65 and 67, the McCormick wells have served ornamental and talismanic purposes, but they were not shown to be potable water supply wells, within the meaning of the rule. At the time of hearing the pumps did not function and were not mounted on the wells. Petitioner St. Johns County's proposed finding of fact No. 76 has been adopted, in substance, insofar as material, except that there was at least one effort to collect toxic wastes in Jacksonville. With respect to petitioner St. Johns County's proposed findings of fact Nos. 77 through 94, proposed permit conditions are not proposed findings of fact. With respect to petitioner St. Johns County's proposed finding of fact No. 124, the evidence was clear that more wetlands were to be destroyed than were to be created. Petitioner St. Johns County's proposed finding of fact No. 125 is rejected as against the weight of the evidence. With respect to petitioner St. Johns County's proposed findings of fact Nos. 126, 127 and 128, mitigation , particularly as regards the wood stork, if the landfill is built. Petitioner St. Johns County's proposed finding of fact No. 129, Durbin Creek enters Julington Creek, shortly before the latter reaches the river. Findings of fact proposed by petitioners J.T. McCormick and the Estate of Benjamin R. McCormick (McCormicks) Nos. 1-4, 6-10, 13, 15-17, 20, 21 and 23 have been adopted, in substance, insofar as material. With respect to McCormicks' proposed finding of fact No. 5, a preponderance of the credible evidence did not establish that the wells would be used to supply potable water in the future, even if the pumps are repaired to make it possible. Nor did the evidence establish any such authentic, "non-forensic," use in the past. With respect to McCormicks' proposed finding of fact No. 11, evidence was adduced that other sites had been considered by engineers the City engaged. T. 2224-5. With respect to McCormicks' proposed finding of fact No. 12, testimony put the delay at two to three months. T. 2139. The City could have avoided this delay. McCormicks' proposed finding of fact No. 14 has been adopted, in substance, insofar as material, except that the proportion of the Class III waste stream construction and demolition debris comprises is not stated at T. 2149. With respect to McCormicks' proposed findings of fact Nos. 18 and 19, the four and six cents per ton computations ignore the time value of money, among other things. McCormicks' proposed finding of fact No. 22 is immaterial. McCormicks' proposed finding of fact No. 24 is properly a proposed conclusion of law. Findings of fact proposed by Florida Wildlife Federation, Inc., St. Johns County Audubon Society, Sierra Club, Inc., Coastal Environmental Society and River Systems Preservation, Inc. came in two unnumbered installments. Findings of fact have addressed the substance of each. Without numbering, it is difficult to treat the material. Petitioner STOP's proposed findings of fact Nos. 5-7, 9-10, 12-18, 20, 22- 24, 26-27, 29, 32-47, 49, 50, 52, 55-57, 59-60, 62, 63, 66, 67, 69, 70, 72 and 73 have been adopted, in substance, insofar as material. Petitioner STOP's proposed findings of fact Nos. 1-4, 30, 31, 65, 71, 75 and 76 are properly proposed conclusions of law in part and relate otherwise to DER's preliminary analysis, which is technically immaterial. With respect to petitioner STOP's proposed findings of fact Nos. 8 and 58, Mr. Kappes said he had seen alligator on site but, when asked for specifics, testified to tracks they had left in the southeast corner of the site. Equally ambiguously, the City stated in its draft application that alligator had been "noted" on the property. The evidence did not show that ospreys are protected or listed in Duval County. Petitioner STOP's proposed findings of fact Nos. 11 and 74 relate to subordinate matters. With respect to petitioner STOP's proposed finding of fact No. 19, the inference that all commensals is present is problematic here, since the gopher tortoises were relocated by man from a site many miles away. With respect to petitioner STOP's proposed finding of fact No. 21, 80 to 82 of 105.7 acres of gopher tortoise habitat would be destroyed. Petitioner STOP's proposed finding of fact No. 25 is immaterial to this application. With respect to petitioner STOP's proposed finding of fact No. 28, Mr. Wiley so testified. With respect to petitioner STOP's proposed findings of fact Nos. 48, 51 and 64, although the conservation easement on uplands would not result in additional habitat, it would preclude further diminution. With respect to petitioner STOP's proposed findings of fact Nos. 53 and 54, no eagles are currently nesting on site, and Eagle Nest Island, where eagles nested until 1983, is off site. With respect to petitioner STOP's proposed finding of fact No. 61, the evidence did not establish that Mr. Kappes saw the red-cockaded woodpecker on site, even though he found six active nests within three miles of the site. With respect to petitioner STOP's proposed finding of fact No. 68, Dr. White so testified. DER's proposed findings of fact Nos. 1-9, 11-15, 17, 24, 26, 33, 37, 39, 41-45, the first three sentences of No. 50, Nos. 52-56, 62-64, 66, 67, except as regards inherent legislative facts, 70-87, 89-92 and 95 have been adopted, in substance, insofar as material. With respect to DER's proposed finding of fact No. 10, 0.9 acres of wetlands contiguous to Durbin Swamp and within the jurisdiction of the St. Johns River Water Management District would be used for a storm water retention basin. DER's proposed findings of fact Nos. 18 and 20 have been adopted, in substance, except that these steps do not ensure or guarantee a quick return of water quality functions. DER's proposed findings of fact Nos. 21, 32, 35, the last sentence of No. 50, Nos. 51, 88 have been rejected as against the weight of evidence. With respect to DER's proposed findings of fact Nos. 22 and 28, mitigation areas with deep ponds in the middle will permit fish to avoid the conditions under which wood storks feed. With respect to DER's proposed finding of fact No. 23, the steep sided ponds, sparser canopies and lesser extent of created isolated wetlands offset their "higher quality." With respect to DER's proposed finding of fact No. 25, the mitigation proposed does not amount to a one to one ratio. While significant, the easements preserve the status quo and do not compensate for lost wetland functions. With respect to DER's proposed finding of fact No. 27, the evidence suggested no reason why bears would not forage in isolated, as well as contiguous wetlands. With respect to DER's proposed finding of fact No. 29, to the extent possible, existing trees would be transplanted; if they all survived, the number of perches would be undiminished, except for branches broken in the process. With respect to DER's proposed finding of fact No. 30, sightings nearby and habitat on site amount to evidence of use of the site. As regards the indigo snake, testimony that these animals were introduced to the site was uncontroverted. With respect to DER's proposed finding of fact No. 31, alligator tracks were found in the southeastern part of the site. With respect to DER's proposed finding of fact No. 34, no southeastern kestrel nests were found on site. With respect to DER's proposed finding of fact No. 36, it is not in the public interest to issue a permit for a lined landfill that would cause pollution in violation of DER's water quality standards. If a landfill were properly permitted, it would be in the public interest to have access. With respect to DER's proposed finding of fact No. 38, the first sentence (which seems to contradict the fourth) has been adopted, in substance, insofar as material. With respect to DER's proposed finding of fact No. 40, there was no evidence of cumulative impacts to Durbin Swamp, as opposed to Durbin and Julington Creeks. With respect to DER's proposed findings of fact Nos. 46-48, the clayey sand, placed in two six-inch lifts, would have much greater permeability as a unit than samples of the same material screened for certain imperfections and tested in the laboratory. In the field, it would not be possible to remove all clods and other materials that make for greater vertical hydraulic conductivity of the unit. Subgrade mixing would occur, in putting down the first of the two lifts. A 12-inch layer would be many more times transmissive than a liner of the same material put down in six six-inch lifts to attain the three feet DER requires, when no synthetic liner is used. Mr. Fluet did not testify that a 12-inch layer would achieve a permeability of 1 x 10-7 centimeters per second. He testified that nobody who had studied 12-inch layers had reported permeability of less than 1 x 10-5 centimeters per second for a clayey layer of that thickness. With respect to DER's proposed finding of fact No. 49, the geomembrane is subject to the effects of pressure and temperature variation would contribute to wrinkling. With respect to DER's proposed finding of fact No. 57, leachate leakage would diminish after closure, but would not stop altogether. With respect to DER's proposed findings of fact Nos. 59 and 60, the working hypothesis is that even a single molecule of certain leachate constituents may initiate cancer, although concentrations below the levels identified are said to pose no more than an acceptable risk of doing so. DER's proposed finding of fact No. 61 describes the methodology correctly, but the particular results have not been accepted. With respect to DER's proposed finding of fact No. 65, predicted concentrations depend on the leakage rate assumed. With respect to DER's proposed finding of fact No. 68, data showing the composition of discharges to ground water from other Class III landfills were not presented. Supposed "legislative facts" do not constitute evidence. With respect to DER's proposed finding of fact No. 69, the evidence did not show what concentrations of biocides or other chemical constituents were likely to be. With respect to DER's proposed finding of fact No. 93, the phrase "monitoring well" was not used. With respect to DER's proposed finding of fact No. 94, wells Nos. 21 and 22 were between 25 and 35 feet deep. Haydon McCormick testified that a shallow well near the house was for potable water supply. DER's proposed finding of fact No. 96, has been adopted, in substance, except that additional time might not be required for permitting. With respect to DER's proposed findings of fact Nos. 97 and 99, balancing of social and economic interests is appropriate only if hardship is proven, and immaterial otherwise. The City's proposed findings of fact Nos. 1-9, 16-18, 20-25, 30, 33, 35-38, 42, 44, 46, 49, 50, the first two sentences of No. 55, Nos. 58-62, 65, 73, 74, except for the last sentence, Nos. 75, 77-83, 88-92, 94-100, 104, 107, 108 and 110 have been adopted, in substance, insofar as material. With respect to the City's proposed finding of fact No. 10, despite timbering of the uplands the site was characterized as "relatively unaltered." With respect to the City's proposed finding of fact No. 11, no decline in water levels was shown to be irreversible. With respect to the City's proposed finding of fact No. 12, the study was of "trivial value." With respect to the City's proposed finding of fact No. 13, bald eagles and wood storks do make use of the site and indigo snake(s) were set loose there. With respect to the City's proposed finding of fact No. 14, a witness testified to his "confidence" (T.2918) that the kestrel he spotted was a Southeastern kestrel. Signs of alligator were found near the southeast corner of the property. With respect to the City's proposed finding of fact No. 15, hunting was mentioned. The City's proposed findings of fact Nos. 19, 54, 56 and 84 pertain to subordinate matters. With respect to the City's proposed finding of fact No. 26, the witness so testified. With respect to the City's proposed finding of fact No. 27, it was not proven that noise would be "minimized." With respect to the City's proposed finding of fact No. 28, bears could move through the culvert, but elsewhere the access road (particularly during the day), fences and human activity on site would indeed "impede black bear movement in the area." The City's proposed findings of fact Nos. 29, 48, the last sentence of 55, Nos. 57, 71, 72, 85, 87 and the last sentence of 101 have been rejected as being against the weight of the evidence or as unsupported by the preponderance of evidence. With respect to the City's proposed finding of fact No. 31, mobility will not assure successful relocation if existing populations are fully utilizing habitat in the vicinity. The City's proposed findings of fact Nos. 32, 86 and 93 are properly proposed conclusions of law. With respect to the City's proposed finding of fact No. 34, groundwater was shown unlikely to reach solid waste on site. With respect to the City's proposed finding of fact No. 40, the maximum head would not be less than one inch. With respect to the City's proposed finding of fact No. 41, such sand might not be available on site. With respect to the City's proposed finding of fact No. 43, some leachate would leak through the liner. With respect to the City's proposed finding of fact No. 45, some rainwater would infiltrate. With respect to the City's proposed finding of fact No. 47, the evidence did not show that the clayey sand layer would attain so low a vertical hydraulic conductivity. If these liners have performed well, it has not been without leakage, both through flaws and by permeation. With respect to the City's proposed finding of fact No. 51, the subgrade would be inspected, in an effort to assure complete removal of sharp objects. With respect to the City's proposed findings of fact Nos. 52 and 53, permeability is specific to the permeant. The values quoted are for water. High density polyethylene is highly permeable to aromatic hydrocarbons. That liners leak is not speculation. With respect to the City's proposed finding of fact No. 63, the design engineer envisioned circumstances that would require backing leachate up in the landfill. With respect to the City's proposed finding of fact No. 64, violations were proven, in the absence of sufficient attenuation in the vadose zone, and attenuation there was not quantified. With respect to the City's proposed findings of fact Nos. 66 and 67, these evaluations assumed unrealistically low leachate leakage rates. With respect to the City's proposed finding of fact No. 68, this elaborate house of cards bears little relationship to the language of the free from rule. But this approach, too, shows violations, if realistic leakage rates are used. With respect to the City's proposed finding of fact No. 69, credible and credited evidence of dramatically higher leachate leakage rates than they assumed contradicted their conclusions. With respect to the City's proposed finding of fact No. 70, the witness so testified. With respect to the City's proposed finding of fact No. 76, the precise constituents of the Class III leachate were not proven. With respect to the City's proposed finding of fact No. 102, the witness so testified. With respect to the City's proposed finding of fact No. 103, the well that Haydon McCormick jetted in was 25 to 35 feet deep. With respect to the City's proposed findings of fact Nos. 105 and 106, wells could be placed so that enough water drawn from them would reverse the gradient and cause pollutants to move toward the McCormick property. With respect to the City's proposed finding of fact No. 109, the evidence about the effect on operations was ambiguous. With respect to the City's proposed finding of fact No. 111, it is unlikely that the McCormicks would take steps to reverse the flow of groundwater. APPENDIX B Three methods of calculating per defect leachate leakage rates (in cubic meters per second) were proven at hearing, each expressed as an equation or formula requiring values for three variables, for their solution, viz.: h = height of leachate head over defect (in meters) a = area of defect (in square meters) Ks = permeability (vertical hydraulic conductivity) of clayey sand layer beneath defect (in meters per second) The method advocated by the City, published by the EPA, and shown (by the author) to reflect ideal contact between liner components, which does not obtain in practice, is: Q = (0.7) x (h) x (a0.1 x Ks0.88). The method advocated by the County, endorsed by the author of the formula EPA published, and shown to reflect good contact between liner components, shown likely to occur in places, is: Q = (0.21) x (h0.9) x (a0.1 x Ks 0.74) The method advocated by the County, endorsed by the author of the formula EPA published, and shown to reflect poor contact between liner components, shown likely to occur in places, is: Q = (1.15) x (h0.9) x (a0.1 x Ks 0.74) In each case, Q represents the flow of leachate through each defect.

The Issue Schofield Corporation of Orlando has applied to the Department of Environmental Regulation for a permit to construct and operate a Class III trash/yard trash landfill in Orange County, Florida. The issues are whether the applicant is entitled to the permit and, if so, what conditions should attach. Also at issue is Schofield Corporation's motion for attorney's fees and costs, pursuant to Section 403.412(2)(f), F.S.
Findings Of Fact The applicant, Schofield Corporation of Orlando (Schofield), owns the proposed landfill site and existing permits for the site. The proposed site is located in West Orange County, southwest of the intersection of State Road 545 and Schofield Road on the west half of the northwest quarter of section 32, township 23 south, range 27 east, comprising approximately sixty acres within a larger eighty-acre parcel. In some undetermined distant past the site was cultivated in citrus. It is currently being excavated as a borrow pit. The materials proposed to be placed in the landfill include trash, yard trash, construction and demolition debris and clean debris, as defined in DER Rule 17-701.020, F.A.C. The northern half of the site is flat and will be used first for the composting operation. The southern excavated portion of the site will receive the permitted fill material until it is flattened. Then, the two functions will alternate; the composting will occur on the south, and the north end will be excavated to receive fill. The proposed facility will be operated by Chambers Corporation, a nationally recognized waste management company with approximately 20 years of experience in solid waste management. The landfill site will be completely fenced, with a gate entrance mid-site between the landfill and compost area. The gate will be locked when the facility is not in operation, and will be patrolled by security personnel 24 hours a day. "Spotters", or inspectors will be employed to examine incoming waste loads at the gate, from a high gantry, and at the place where the waste is deposited. The loads will be monitored by a television camera, and all haulers will be under contract. The landfill will not accept loads from trucks coming off the road looking for a place to dump. Receptacles will be maintained on site to receive errant non-permitted waste that is found in a load, and that waste will be properly disposed of elsewhere. Schofield has several permits related to its proposed operation. These include a type III landfill permit from Orange County, a compost facility permit from DER, a general construction and demolition debris landfill permit from DER, a surface water management permit from the South Florida Water Management District, and a permit to excavate or mine from the Florida Department of Natural Resources. Schofield also has a contract to receive yard waste from Orange County. The initial term of contract requires at least ten percent of the yard waste to be composted or recycled, with the percentage amount to be renegotiated in subsequent contract renewals. In the hierarchy of landfills, DER considers Class III the least environmentally sensitive. Problems with unauthorized waste and with water quality occur more frequently with Class I landfills, defined as accommodating more than twenty tons a day of residential garbage. In this case DER has proposed to grant Schofield its Class III permit without the requirement of a bottom liner or a leachate or gas control system because of the nature of the waste that will be accepted and because of the rigorous controls, described above, to avoid receiving unauthorized or hazardous waste. The Petitioners are an individual and a homeowners' association representing a residential area approximately a half mile south of the proposed site. Petitioners contend that the applicant's data is insufficient to provide reasonable assurances that water quality standards will not be violated. Petitioners contend that the landfill, if approved, should be required to have a liner to prevent leachate from polluting the groundwater. They further contend that the groundwater monitoring plan submitted by the applicant is inadequate to detect vertical movement of contaminated leachate into the Floridan aquifer, a major source of water supply in Orange County. Hydrogeology The site of the proposed landfill is within a high recharge area. Water percolates rapidly though the soil, moving downward into the aquifer, and laterally off site. The site is considered Karst terrain, underlined with limerock. There is evidence of relic sinkholes, thousands of years old, but there is a low probability of future open sinkhole development. The geology in the area of the site provides adequate structural support for the proposed facility. An aquifer is generally defined as a unit of material which contains water and can give up a sufficient amount of yield to provide some productive flow for pumpage. Below the site there are two aquifers: the shallow water table, or surficial aquifer, containing clean well-drained fine sands, about 70 feet down; and the Floridan, primarily limestone, encountered at a depth of approximately 115 feet. The two are separated by a confining layer of less permeable sands and clay. Flow in the Floridan at the site is primarily from the west to east. Flow in the surficial is also generally from west to east, but the Petitioners theorize, and have presented competent supporting evidence, that there are fissures in the confining layer, allowing some internal drainage within the site, causing surficial water to flow vertically into the Floridan, rather than laterally off-site in an eastward direction. Based on recent data taken from two piezometers installed near the middle of the site, the applicant's hydrogeologist, James Golden, concedes that "mounding" exists along the eastern boundary of the site, reflecting some flow westerly back into the interior of the site. Petitioners' theory regarding internal draining of the site is based in part on data as to groundwater elevation. Groundwater elevation or high groundwater table is the elevation at which water stands on a continuous surface under the site. Jammal and Associates is a consultant firm which has done field studies of this and neighboring sites in the past, for various purposes. Some open bore readings taken by Jammal and Associates in a 1983 study for the Orange County Rapid Infiltration Basin project indicate groundwater table levels on site up to 126 feet, National Geodetic Vertical Data (NGVD). Open bore readings are less reliable than cased hole readings; due to collapses within the hole, artificially high readings are sometimes obtained. Data from the applicant's consultants reveals groundwater tables at 96-98 NGVD. This data was most recently obtained in December 1991 from sealed and surveyed piezometer casings, but not from the area of the site where Jammal's higher readings were obtained. Although it may be conjectured that Jammal's high readings are anomalous, additional sealed borings need to be obtained before the anomaly is confirmed. Groundwater elevations are significant also to determine the depth to which the landfill may be excavated. Based on its December 1991 readings, obtained after the application for permit was filed, the applicant agreed to raise the proposed bottom of the landfill to approximately five feet above the level of the estimated high (wet weather) groundwater table in the area. Water Quality and Monitoring Specific conditions of the proposed permit include DER's requirements that Class GII water quality standards be met at the boundary of the zone of discharge, in accordance with Rule 17-3, F.A.C. The zone of discharge for this facility is a three-dimensional volume defined in the vertical plane as the top of the ground to the base of the most surficial aquifer, and horizontally 100 feet from the edge of the waste-filled area, or the property boundary, whichever is less. The groundwater monitoring plan proposed by the applicant includes one upstream monitoring well on the west side of the site and five wells along the east side of the site, with an additional well at the south, between the project and the Petitioners' residential area. The wells extend down into the upper zone of the surficial aquifer, but not into the deeper limestone Floridan. The downstream wells should detect any contamination in the surficial aquifer flowing from west to east at the zone of discharge. However, they will not pick up contamination draining internally within the site and into the Floridan. Such contamination is possible, even though leachate from Class III- type wastes is expected to be relatively benign. Volatile organic carbons (VOCs) have not typically been a problem in Class III landfills, unless those landfills were previously operated as Class I sites. Secondary drinking water standards for certain metals have been violated at some Class III sites, but such violations are often related to the problem of sampling newly-installed wells. From DER records, Petitioners presented evidence of consistent drinking water quality standard violations in Class III landfills. That such violations can occur in Class III landfills is clearly established. It is not so clear that such violations will occur in this facility, given the proposed controls on load content. However, even acceptable materials will not avoid the production of leachate or gas. Within demolition waste there are chemically bound components which are inseparable, for example, creosote and other preservatives, glues, paints, resins, varnishes and stains. The lignin, tannins and volatile organic acids which are produced when wood decomposes alter the pH of the groundwater. As the water becomes more acidic, heavy metals that were typically bound up in the waste or in the soil, are released in soluble form and travel with the water. The decomposition process occurring in the construction and demolition waste is enhanced by the addition of yard trash which becomes the food source for the biodegradation. Summary of Findings and Proposed Permit Conditions If, as applicant suggests, all groundwater moves primarily from west to east within the site, given the proposed operational controls and the proposed monitoring plan, reasonable assurances have been provided that water quality standards will not be violated beyond the zone of discharge. That is, any contamination likely to occur will be contained within the surficial aquifer and within the 100 feet or property line horizontal boundary. Transmissivity of the surficial aquifer is low enough to allow mixing of the leachate before it reaches the zone of discharge. The Petitioners, however, have presented credible evidence sufficient to question the groundwater flow premise and sufficient to require additional conditions on the permit. If leachate reaches the Floridan through fissures in the confining layer, it will move rapidly off site. In its proposed recommended order DER has suggested additional permit conditions and in its adoption of the proposed recommended order, the applicant has accepted those additional permit conditions. Those permit conditions recognize the fact that data presently provided by the applicant is insufficient to overcome the evidence by Petitioners as to the hydrogeological characteristics of the site with the possibility of internal drainage and vertical intrusion of contaminated water into the Floridan aquifer. The proposed recommended order provides this finding: ...that the ground water monitoring plan as proposed in this proceeding is adequate, provided that there be added to the permit conditions that the permittee conduct appropriate water table testing with cased piezometers during the next wet season to determine whether ground water flow is internal within the site and therefore not intercepted by the present ground water monitoring wells. The permittee shall consult with DER and get approval for the location and construction of these wells prior to their installation. The results shall be immediately submitted to the DER. The ground water monitoring requirements should be modified if necessary at that time pursuant to Rule 17-28.700(5) to assure proper monitoring at this site. (DER proposed Recommended Order, p. 17) The ground water monitoring plan modification suggested by DER is that deeper monitoring wells, into the Floridan aquifer, be required if the additional testing reveals the likelihood of internal on-site ground water drainage. These conditions are still inadequate since they lack specificity with regard to the extent of testing, the location and construction of the wells, and the amendments to the monitoring program to be required if internal drainage is confirmed. Moreover, the proposed conditions fail to address the possibility that the permit should require a liner for the landfill if the data to be obtained reveals the likelihood that contaminates will penetrate into the groundwater of the Floridan. Monitoring programs, however effective, only predict or detect problems; they do not remediate them. Groundwater contamination by landfills is not quickly and easily reversed. Unlike discharges from other facilities such as spray application or deep well injection, the leachate from a landfill is not "turned off". Without the additional data which all parties agree is needed, it is impossible to determine what additional conditions, if any, should be required or what amendments, if any, need to be made to the applicant's proposed monitoring plan.

Findings Of Fact The Proposed Permit This case involves a 65-acre site in north Lee County owned by the City of Ft. Myers. At all material times, the land has been zoned under industrial- equivalent designations. By leases that are not part of this record, Ft. Myers has leased 21.4 acres of the 65 acres to various governmental agencies, including Lee County, Lee County Sheriff's Office, and possibly the Florida Department of Juvenile Justice (formerly known as Department of Health and Rehabilitative Services). The following facilities are presently located on the 21.4 acres: Juvenile Detention Center, Lee County Stockade, Price Halfway House, Sheriff's Office Aviation Department, and Emergency Operations Center. By lease dated September 20, 1993, Ft. Myers leased the remaining 43.6 undeveloped acres to Lee County for a term of 50 years. This lease allows Lee County to use the 43.6 acres for $1 per year, but only for the operation of a Juvenile Justice Facility. Under Paragraph 20 of the lease, Ft. Myers may terminate the lease if Lee County ceases to operate the facility. Likewise, Lee County may terminate the lease if the Department of Juvenile Justice ceases to fund the County's operation of the facility. Under the lease, preference is given to juvenile residents of Ft. Myers. Paragraph 22 of the lease allocates liability to Lee County for claims or damages arising from released fuels, including from pipelines. The lease is not assignable without Ft. Myer's consent. By agreement dated December 17, 1993, Ft. Myers consented to the sublease of the entire 43.6- acre parcel to the Department of Juvenile Justice for the purpose of the construction of a juvenile residential commitment facility. Lee County receives no rent from the Department of Juvenile Justice. In Paragraph 10 of the agreement, the Department of Juvenile Justice agrees to maintain, at its expense, "all improvements of every kind . . .." Lee County must make any repairs to improvements if the Department of Juvenile Justice fails to do so. By subsequent agreement, Respondent Department of Management Services (DMS) became the agent for the Department of Juvenile Justice for the design, permitting, and construction of the juvenile justice facility. By Application for a surface water management permit executed June 16, 1994, DMS applied for a surface water management permit for the construction and operation of a 10.9- acre project known as the Lee County Juvenile Commitment Facility. This 10.9-acre project is part of the 43.6 acres leased to Lee County and subleased to the Department of Juvenile Justice. The application states that the existing 21.4 acres of developed sites, which are leased under separate agreements to different governmental entities, "will be permitted as is." The Staff Review Summary of Respondent South Florida Water Management District (SFWMD) describes the purpose of the application as follows: This application is a request for Authorization for Construction and Operation of a surface water management system to serve a 10.9 acre Institutional project discharging to Six Mile [Cypress] Slough via onsite wetlands and road- side swales. The application also requests Authorization for Operation of a surface water management system serving a 21.4 acre existing facility and 32.7 acres to remain unchanged for a total permitted area of 65.0 acres. Staff recommends approval of both authorizations with conditions. The Staff Review Summary accurately states that the owner of the land is Ft. Myers. Of questionable accuracy is the statement that Ft. Myers leases to Lee County the 21.4 acres devoted to the five existing facilities. Although Lee County probably is a lessee of some of these parcels, the Lee County Sheriff's Office is the lessee (or perhaps sublessee) of at least two parcels. One of the other parcels may involve a state agency, again under either a lease or a sublease. The Staff Review Summary inaccurately states that the project developer is Lee County. The project developer is DMS or its principal, the Department of Juvenile Justice. The Staff Review Summary reviews the existing development on the 21.4 acres. The improvements consist of the 4.8-acre Juvenile Detention Center, 2.9- acre Price Halfway House, 4.7-acre Lee County Stockade, 5.1-acre Sheriff's Office Aviation Department, and 3.9-acre Emergency Operations Center. The Staff Review Summary states that the footer of the Juvenile Detention Center was inspected in February 1980. The site drains into a 1.2- acre retention pond, which was a natural pond dug out to accept the drainage from the Juvenile Detention Center. A small amount of surface flow drains from the Juvenile Detention Center to a perimeter swale that drains west into a ditch running along Ortiz Avenue. The Staff Review Summary states that the building permit for the Price Halfway House was issued in October 1982. The site drains into the 1.2-acre retention pond, which was apparently enlarged a second time to accept the additional flow. A small amount of the flow from the Price Halfway House also drains to the perimeter swale and west into the Ortiz Avenue ditch. The Staff Review Summary states that the building permit for the Lee County Stockade was issued on May 25, 1976. SFWMD issued an exemption and a determination that no permit was required for two additions to the stockade in 1988 and 1989. For the additional impervious surface added by these additions, one inch of water quality treatment was provided. After the abandonment of a pumping system, drainage of the stockade site consists of water building up in existing onsite ditches and sheet flowing into the Ortiz Avenue ditch. The Staff Review Summary adds that a small retention area constructed at the southeast corner of the site treats stormwater from the stockade and the Sheriff's Office Aviation Department. The summary adds that a small amount of stormwater drains north into an exterior swale that drains into the Ortiz Avenue ditch. The Staff Review Summary states that a building permit was issued for the Sheriff's Office Aviation Department in August 1977. Stormwater from the site sheetflows to exterior swales north and south of the building. When the swales fill up, the water flows into the Ortiz Avenue ditch. The Staff Review Summary states that a building permit was issued for the Emergency Operations Center on October 11, 1977. Drainage from the center flows directly into the Ortiz Avenue ditch. Under "Water Quality," the Staff Review Summary reports that SFWMD "did not require compliance with discharge rate or criteria" based on Section 1.6, Basis of Review for Surface Water Management Permit Applications within the [SFWMD] March 1994 (Basis of Review), which contains guidelines issued by SFWMD for the construction and operation of surface water management systems. The summary adds that there have been no "water quality or quantity complaints associated with this site over the past 18 years since its initial construction." Noting that a surface water management permit is requested for the entire 65-acre parcel, the Staff Review Summary states that the above-described drainage systems for the five existing facilities are "operational and will remain as they now exist." Turning to the proposed development, the Staff Review Summary states that the remaining 43.6 undeveloped acres "will also be leased to Lee County by the City for the proposed commitment facilities." The facilities are accurately described as a 5.2-acre halfway house and a 5.7-acre bootcamp, both of which will be drained by internal drainage swales and culverts flowing into detention areas, which will discharge through a control structure into onsite wetlands leading to the Ortiz Avenue swale. Addressing designed discharge rates, the Staff Review Summary acknowledges that the bootcamp's discharge rate will exceed the allowable rate for a 25-year, three-day storm event. The allowable rate is .33 cfs, and the design rate is .37 cfs. The Staff Review Summary explains that this discrepancy results from the use of the minimum size orifice (three inches) in the control structure. Addressing water quality, the Staff Review Summary reports that commercially zoned sites are required to provide one-half inch dry pretreatment for water quality unless reasonable assurance can be provided that hazardous material will not enter the surface water management system. Determining that no hazardous material will be stored or generated on the site, SFWMD did not require the one-half inch dry pretreatment of runoff. Noting that no surface water management permits have ever been issued for any part of the 65-acre parcel, the Staff Review Summary recommends that, subject to the customary Limiting Conditions, SFWMD issue: Authorization for Construction and Operation of a 10.9 acre Institutional Project discharging to Six Mile Cypress Slough via onsite wetlands and roadside swales, Operation of a 21.4 acre existing facility and 32.7 acres to remain unchanged for a total permitted area of 65.0 acres. Limiting Condition 4 states that the permittee shall request transfer of the permit to the "responsible operational entity accepted by [SFWMD], if different from the permittee." Limiting Condition 8 adds: A permit transfer to the operation phase shall not occur until a responsible entity meeting the requirements in section 9.0, "Basis of Review . . .," has been established to operate and maintain the system. The entity must be provided with sufficient ownership or legal interest so that it has control over all water management facilities authorized herein. Special Condition 11 states: "Operation of the surface water management system shall be the responsibility of Lee County." The Permittee and the Entity Responsible for Maintenance The proposed permit consists of two authorizations. The first authorization is for the construction and operation of the surface water management system on the 10.9-acre parcel on which will be constructed the bootcamp and halfway house. The second authorization is for the operation of the existing surface water management system on the already-developed 21.4 acres and the unimproved surface water management system on the remaining 32.7 acres. There are two problems with the designation of Lee County as the entity responsible for maintaining the permitted surface water management systems. Basis of Review 9.1.B states: To satisfy [P]ermit [L]imiting [C]ondition [8], the Permittee must supply appropriate written proof, such as either by letter or resolution from the governmental entity that the governmental entity will accept the oper- ation and maintenance of all the surface water management system components . . .. The authorization for operation of the systems on the 21.4-acre and 32.7-acre parcels does not await any construction. Once the permit is issued, the authorization is effective. Therefore, all prerequisites to the designation must have been satisfied before the operation permit issues. For the 21.4-acre parcel, DMS has not provided reasonable assurance that Lee County is the lessee or sublessee of all of the parcels underlying the five existing facilities. In fact, it appears that Lee County is not the lessee or sublessee of all of these parcels. Even if Lee County were the lessee or sublessee of these five parcels, DMS has not provided reasonable assurance that Lee County has assumed responsibility for the maintenance of the surface water management system for the five parcels. Contrary to Basis of Review 9.1.B, there is no written agreement by Lee County to assume operational responsibility, nor is there even an actual agreement to this effect. SFWMD's rules sensibly require that written consent be obtained before the operation permit is issued. Likewise, DMS has failed to show that Lee County has agreed to assume responsibility for the operation and maintenance of the surface water management system for the 32.7-acre parcel. Again, SFWMD must obtain written consent before issuing the permit because no construction will precede operation for the surface water management system on this parcel. Unlike the situation as to the 21.4-acre parcel, the 32.7-acre parcel is leased to Lee County as part of the 43.6- acre parcel. But in the December 17, 1993, agreement, the Department of Juvenile Justice, not Lee County, assumes responsibility for maintaining all improvements, which arguably includes drainage improvements. As between Ft. Myers and Lee County, Lee County assumes secondary liability for the maintenance of all improvements. But the failure of the Department of Juvenile Justice to do so would likely represent a default under the agreement. In such a case, the lease and separate agreement probably would either be in litigation or Lee County would have terminated its obligations under the contracts. In either case, it is unlikely that Lee County would perform its secondary responsibility to maintain the drainage improvements, especially where it is receiving no rent from the Department of Juvenile Justice and priority is given to Ft. Myers juveniles in admission decisions. Construction will precede operation as to the 10.9- acre parcel so the parties have an opportunity, even after the construction and operation permit is issued, to secure the necessary written consent before the operation permit goes into effect. But similar deficiencies exist with respect to the 10.9- acre parcel because the same agreement imposes upon the Department of Juvenile Justice, not Lee County, the obligation to maintain improvements. An additional complication arises as to the 10.9-acre parcel. The Department of Juvenile Justice intends to contract with one or more private entities to operate the bootcamp and halfway house, so there is at least one more party that Lee County could claim was responsible for maintenance of the surface water management system. The question of who is responsible for maintaining the surface water management systems is important. Drainage quantities and directions can change if swales clog up with vegetation or other matter. In this case, one roadside swale in the area of the 21.4-acre parcel is blocked with vegetation. DMS and SFWMD have thus failed to provide reasonable assurance that the designated entity has assumed responsibility for the maintenance and operation of the existing systems or will assume responsibility for the maintenance and operation of the proposed system following its construction. Permit for Existing Development Section 1.6, Basis of Review, states: [SFWMD] issues construction and operation permits for proposed surface water management activities and operation permits for existing systems. The criteria herein are specifically designed to apply to proposed activities (construction and operation permits). Therefore, some of the criteria may not be applicable to the permitting of existing systems (operation permits). For example, in some cases, existing systems may not meet flood protection criteria. Criteria deviation for existing systems will be identified in staff reports. SFWMD has produced no evidence explicating the extent to which existing systems, such as the systems on the 21.4- and 32.7-acre parcels, are entitled to operating permits without meeting some of the criteria applicable to proposed systems, such as the system on the 10.9-acre parcel. There is nothing whatsoever in the record to explain why certain existing systems might not have to meet certain criteria, such as flood protection criteria. Except for the quantity deviation discussed below, there is nothing in the record disclosing the extent to which SFWMD has waived, or even considered the applicability of, certain or all criteria prior to the issuance of operation permits for the existing systems. In practice, SFWMD does not adhere even to the vague standards implied in 1.6. According to the SFWMD witness, the practice of SFWMD, as reflected in this case as to the systems on the 21.4- and 32.7-acre parcels, is to permit existing systems "as is, where is," as long as they have had no reported problems. There are numerous deficiencies in the "as is, where is" unwritten policy, apart from the obvious one that it conflicts with the assurance of 1.6 that only "some of the criteria may not be applicable" to existing systems. First, the record does not define what a "problem" is. Second, the record discloses no means by which reported problems are collected and later accessed, such as by a parcel index. The "as is, where is" policy is an abdication of the limited responsibilities that SFWMD imposes upon itself in 1.6, especially when applied to the present facts. The facts are straightforward. Neither Ft. Myers, Lee County, nor any other party has ever obtained a permit for any surface water management system, despite numerous improvements in the past 20 years requiring such permits, including the construction of a heliport, at which maintenance and refueling of helicopters takes place. In two relatively minor cases, discussed below, SFWMD erroneously determined that no permit was required. In one of those cases, the applicant, Lee County, candidly admitted the existence of a flooding problem. Based on the present record, neither DMS nor SFWMD has justified the issuance of an operation permit for the systems on the 21.4- and 32.7-acre parcels based either on Basis of Review 1.6 or on the "as is, where is" unwritten policy. Construction of the five improvements on the 21.4 acres began between 1975 and December 1977 with construction of a portion of the Lee County Stockade building and parking, Emergency Operations Center building and parking, and a now- removed barn for the Lee County Sheriff's Office. At the same time, a lake was dug, probably for fill purposes. By the end of 1977, about 2.39 acres of the 21.4 acres were converted to impervious surface. From 1978 to March 1980, another 0.96 acres of the 21.4 acres were converted to impervious surface by the construction of a perimeter dike and road. During this period, construction commenced on the Juvenile Detention Center, adding another 1.63 acres of impervious surface. Between March 1980 and December 1981, additions were made to the Lee County Stockade building and the lake for an additional 0.45 acres of impervious area. Between December 1981 and March 1984, the Price Halfway House building and parking were constructed, adding another 0.79 acres of impervious surface. Between March 1984 and February 1986, a heliport facility and landing area were constructed for the Lee County Sheriff's Office, adding another 1.01 acres of impervious surface. Between February 1986 and February 1990, an additional 2.31 acres of impervious surface were added through additions to the Lee County Stockade and parking area, juvenile detention center, and Emergency Operations Center parking area. Between February 1990 and April 1993, another addition to the Lee County Stockade added 0.62 acres of impervious surface. An additional 0.17 acres of lake was excavated. During this time, applicable rules and statutes required permits for the construction of "works" affecting surface water, including ditches, culverts, and other construction that connects to, or draws water from, drains water into, or is placed in or across the waters in the state. The buildings, parking, other impervious surfaces, ditches, swales, dikes, lake excavations, and, at one point, addition of a now- abandoned pump all constituted "works" for which surface water management permits were required. In 1988, Lee County or Ft. Myers applied for an exemption for an addition to the Lee County Stockade. The basis for the claim of exemption was that the parcel consisted of less than 10 acres and the total impervious surface did not exceed two acres. Although rules in effect at the time required consideration of the contiguous 65 acres under common ownership and the total impervious surface for the 9.7-acre "parcel" exceeded two acres, SFWMD erroneously issued an exemption letter. The second instance involving a claim of exemption took place in 1989 when Lee County submitted plans for another addition to the Lee County Stockade, adding 0.51 acres of impervious surface. The submittal acknowledged a "flooding" problem, but promised a master drainage plan for the "entire site." SFWMD determined that no permit would be required due to the promise of a master drainage plan. No master drainage plan was ever prepared. The flooding problem precluded issuance of the operation permit on an "as is, where is" basis for the already-developed 21.4-acre parcel, even assuming that SFWMD adequately justified the use of this unwritten permitting procedure. In fact, SFWMD has not explained adequately its "as is, where is" permitting procedure or even the undelineated permitting criteria referenced in 1.6, Basis of Review. The 65- acre parcel is a poor candidate for preferential permitting of existing systems. The owner and developer constructed the existing systems in near total disregard of the law. The two times that the owner and developer complied with the permitting process involved small additions for which exemptions should not have been granted. In one case, SFWMD exempted the proposed activity due to its error calculating minimum thresholds as to the areas of the parcel and the impervious surface. In the other case, SFWMD exempted the proposed activity partly in reliance on a promised master drainage plan that was not later prepared. To issue operation permits for the existing systems on the 21.4- and 32.7-acre parcels would reward the owner and developer of the 65-acre parcel for noncompliance with the law and provide an incentive for similarly situated landowners and developers likewise to ignore the law. Before issuing operation permits on systems that have received no comprehensive review and that have been added piecemeal over the years, SFWMD must evaluate the surface water systems on the entire 65-acre parcel to determine whether they meet all applicable criteria. The "as is, where is" unwritten policy has no applicability where there have been reports of flooding. If SFWMD chooses to dispense with criteria in reliance upon Basis of Review 1.6, it must be prepared to identify and explain which criteria are waived and why. Water Quality Basis of Review 5.2.2 provides that projects that are zoned commercial or industrial, such as the present one, must provide one-half inch of "dry" detention or retention pretreatment, unless reasonable assurances are provided "that hazardous materials will not enter the project's surface water management system." There is no existing or proposed dry detention on the 65 acres. The existing development includes the Sheriff's Office Aviation Department, which serves as a heliport. The fueling and maintenance of helicopters means that contaminants may enter the stormwater draining off the site. The functioning of the surface water system on this site is therefore of particular importance. There also may be more reason to question the functioning of the surface water system on this site. It is south of the Lee County Stockade, where flooding has been reported. The heliport site has also been the subject of more elaborate drainage improvements, such as the location of a small retention pond near the Stockade boundary and a pump, the latter of which has since been abandoned. The existing system on the 21.4-acre parcel, as well as the existing and proposed systems on the remainder of the 65 acres, require dry pretreatment for reasons apart from the presence of the heliport. The materials likely to be used with the existing and proposed developments are similar to those found on residential sites. SFWMD and DMS contend that there is therefore no need to require dry pretreatment as to these areas. However, the existing and intended institutional uses, such as jails and bootcamps, represent an intensity of use that exceeds the use typical in areas zoned residential. This increased intensity implies the presence of typical residential contaminants, such as petroleum-based products or cleaning solvents, but in greater volumes or concentrations, if not also, in the case of solvents, different compositions. The lease addresses potential liability for released petroleum. In the absence of a showing that such hazardous materials are prevented from entering the runoff, SFWMD must require dry pretreatment for the systems occupying the entire 65-acre parcel. DMS and SFWMD have thus failed to provide reasonable assurance that the existing systems satisfy applicable water quality criteria or that the proposed system will satisfy applicable water quality criteria. Water Quantity The 65-acre parcel adjoins Ortiz Avenue on the west and property owned by Petitioners on the east and south that is undeveloped except for a borrow pit some distance from the 65- acre parcel. The parcel is roughly 1000 feet east- west and 2700 feet north-south. The proposed halfway house is at the north end of the parcel. The halfway house is situated between a proposed detention pond on the west and a recreation field on the east. A paved road divides the halfway house from the rest of the 65- acre parcel. South of the road are the Lee County Stockade on the west, which abuts Ortiz Avenue, and the Juvenile Detention Center on the east. A berm separates these two sites. The berm runs from the road along the west shore of the twice- enlarged 1.2- acre retention pond and the west boundary of the Price Halfway House, which is south of the Juvenile Detention Center. To the west of the berm, south of the Lee County Stockade, is the Sheriff's Office Aviation Department or heliport facility, which abuts Ortiz Avenue. South of the Aviation Department is an outparcel used by the Florida Department of Corrections that also abuts Ortiz Avenue. East of the outparcel is the proposed halfway house with a proposed detention pond west of the halfway house and south of the outparcel. The Emergency Operations Center, which abuts Ortiz Avenue, is south of the detention pond and surrounded on three sides by the 32.7 acres to be left undisturbed at this time. There are perimeter berms around all of the parcels except for the Juvenile Detention Center and Price Halfway House, which are served by a single berm, and the Emergency Operations Center, which appears not to be bermed. The prevailing natural drainage is not pronounced either by direction or volume because the land is nearly level. The natural direction of drainage is to the south and west and remains so on Petitioners' land to the east and south and the undisturbed 32.7 acres to the south. The variety of drainage directions within the remainder of the 65- acre parcel reflects the extent to which berms, swales, ponds, pumps, roads, buildings, parking areas, and other works have been added to the northerly parcels. Runoff reaching the northern boundary of the 65 acres will be diverted due west around the proposed detention pond to the swale running along the east side of Ortiz Avenue. Runoff from the recreation field and halfway house building and parking area drain into the proposed detention pond, which releases water through a gravity control device to the Ortiz Avenue swale. There appears to be a connection routing some runoff from the south side of the recreation field to the Juvenile Detention Center, where it travels west in a roadside swale to the Ortiz Avenue swale. A little less than half of the area of the Juvenile Detention Center site drains into perimeter swales along the north and east borders and then to the west before emptying into the Ortiz Avenue swale. The remainder of the Juvenile Detention Center drains into the retention pond. The same is true of the Price Halfway House. The Lee County Stockade drains to each of its borders where the water then runs west along the north or south border to the Ortiz Avenue swale. The southern half of the Lee County Stockade site drains into the small retention pond at the northwest corner of the Sheriff's Office Aviation Department. Most of the runoff from the heliport facility runs to the southwest corner of the parcel, which is the location of the abandoned pump. From there, the runoff continues to the Ortiz Avenue swale. Very little if any of the runoff from the heliport enters the small retention pond on the northwest corner of the parcel. The bootcamp drains into the detention pond, which then releases water by a gravity control structure into a portion of the undisturbed 32.7-acres before entering the Ortiz Avenue swale. The Emergency Operations Center site drains in all directions away from the building and parking area, eventually draining into the Ortiz Avenue swale. Stormwater discharge rates from the proposed halfway house and bootcamp are 0.28 cfs and 0.37 cfs. Under SFWMD rules, the allowable maximums in the Six Mile Cypress drainage basin are 0.30 cfs and 0.33 cfs, respectively. SFWMD and DMS contend that the excessive discharge from the bootcamp is acceptable because the gravity control device for the proposed detention pond is of the smallest size allowable, given the indisputable need to avoid clogging and ensuing upstream flooding. Initially, SFWMD approved the discharge rates for the halfway house and bootcamp because, when combined, they did not exceed the total allowable value. However, this approach was invalid for two reasons. First, the two sites contain entirely independent drainage systems separated by several hundred feet. Second, after correcting an initial understatement for the value for the halfway house, the actual total exceeds the maximum allowable total. SFWMD contends that the slight excess is acceptable because of the inability to use a smaller orifice in the gravity control structure. However, the discharge quantity easily could have been reduced by design alternatives, such as enlarging the detention pond, which is mostly surrounded by land that is to be left undisturbed. The ease with which the minimum-orifice problem could have been avoided rebuts the presumption contained in Basis of Review 7.2.A that excessive discharge quantities are presumably acceptable if due to the inability to use a smaller orifice. Also, SFWMD and DMS have failed to show that the effect of the excessive discharge quantities is negligible, so the exception in the SFWMD manual for negligible impacts is unavailable. Neither SFWMD nor DMS provided any reasonable assurance as to the quantity of discharge from the 21.4 acres. Rough estimates suggest it is more likely that the quantity of discharge may greatly exceed the allowable maximum. SFWMD must evaluate the water-quantity issues before issuing operation permits for the systems on the 21.4- and 32.7- acre parcels and a construction and operation permit for the 10.9-acre parcel. Obviously, if SFWMD determines that all water quantity criteria are met as to the existing systems, it may issue operation permits for the systems on the 21.4- and 32.7- acre parcels. Otherwise, SFWMD must quantify the extent of the deviation and, if it seeks to waive compliance with any or all quantity standards in reliance on Basis of Review 1.6, evaluate the effect of the waiver and explain the basis for the waiver. DMS and SFWMD have thus failed to provide reasonable assurance that the existing systems satisfy applicable water quantity criteria or that the proposed system will satisfy applicable water quantity criteria. Impacts on Adjacent Lands Petitioners' property is impacted by the above- described drainage in two ways. First, Petitioners' property abutting the east side of Ortiz Avenue, south of the 65 acres, is especially vulnerable to flooding because the Ortiz Avenue swale is not a V-notch, but a half-V. The closed side of the swale prevents the water from running onto Ortiz Avenue. The open side of swale abuts Petitioners' property, so, if the swale's capacity is exceeded, stormwater will be released onto Petitioners' land. Second, perimeter berming along the east side of the 10.9- and 21.4- acre parcels will impede flow off the part of Petitioners' property located to the east of the 65 acres. A swale between the proposed halfway house and the Juvenile Detention Center will receive runoff from a small portion of Petitioners' property to the east and mostly north of the 65 acres. But there is no indication how much runoff from Petitioners' property can be so accommodated, how much runoff is impeded by the existing berm along the east side of the Juvenile Detention Center and Price Halfway House, and how much runoff will be impeded by the addition of new berms along the east side of the proposed halfway house and bootcamp. Basis of Review 6.8 requires that swales and dikes allow the passage of drainage from off-site areas to downstream areas. Rule 40E-4.301(1)(b), Florida Administrative Code, requires that an applicant provide reasonable assurances that a surface water management system will not cause adverse water quality or quantity impacts on adjacent lands. Neither SFWMD nor DMS obtained topographical information for Petitioners' property, as required by the Basis of Review. Rough estimates suggest that the proposed project may require Petitioners' property to retain considerably more stormwater from the design storm event of 25 years, three days. DMS and SFWMD have thus failed to provide reasonable assurance that the proposed system would not have an adverse impact on Petitioners' upstream and downstream land.
Recommendation It is hereby RECOMMENDED that the South Florida Water Management District enter a final order denying the application of the Department of Management Services for all permits for the operation and construction and operation of surface water management systems on the 65-acre parcel.

The Issue Whether Permit No. DO19-101251 issued to Mr. Vail on July 11, 1985 to construct and operate an on-site wastewater treatment and disposal system should be revoked?
Findings Of Fact Mr. Vail is the owner and operator of a business called the St. George Inn and Restaurant (hereinafter referred to as the "Inn"). The Inn is located at the southeast corner of the intersection of Franklin Boulevard and Pine Avenue on St. George Island, Florida. In May of 1984 Mr. Vail spoke with an employee of the Department of Health and Rehabilitative Services about obtaining a permit to construct a septic tank on his property for use by the Inn for the treatment and disposal of wastewater. Mr. Vail was instructed to submit a design of the septic tank for approval. Mr. Vail contracted with McNeill Septic Tank Company for the design and construction of the septic tank. The evidence failed to prove when Mr. Vail applied with the Department of Health and Rehabilitative Services for a permit. As of March, 1985, however, Mr. Vail had not received approval or disapproval of his application from the Department of Health and Rehabilitative Services. Mr. Vail, therefore, went to the Governor's office to seek help in getting a response. Shortly after contacting the Governor's office, the Department of Health and Rehabilitative Services informed Mr. Vail that he needed to obtain a permit from the Department and not from the Department of Health and Rehabilitative Services. On or about March 18, 1985, Mr. Vail filed an Application to Operate/Construct Industrial Wastewater Treatment and Disposal Systems (hereinafter referred to as the "Application"), with the Department. The Application was prepared by Brown and Associates Civil Engineers and Land Surveyors, Inc., Mr. Vail's engineering consultant. The Application was certified by Benjamin E. Brown, Professional Engineer. Mr. Vail signed the Application as "owner" and indicated that he was aware of the contents of the Application. In the Application, "St. George Inn Restaurant" is listed as the "Source Name." Under Part II, A of the Application, the applicant is asked to "[d]escribe the nature and extent of the project." In response to this request, the following answer was given: This project will provide a sewage disposal system for a one hundred and fifty (150) seat restaurant on St. George Island. Sizing of the septic tank system is based on 50 GPD/seat and secondary treatment will be provided by the design proposed. Under Part III, A of the Application, the applicant is asked to provide the following information and the following answers were given: Type of Industry Restaurant . . . . 3. Raw Materials and Chemicals Used Food preparation only. Normal Operation 12 hrs/day 7 days/week . . . . If operation is seasonal, explain This restaurant will be used the most during the summer months which corresponds with ocean/beach recreation & the tourist trade. Nowhere in the Application is it indicated that the permit applied for involved anything other than a restaurant. The Application gives no information from which the Department could have known that the proposed wastewater treatment and disposal system would handle waste from guest rooms or an apartment. In the Application Mr. Vail sought approval of a permit to construct and operate a wastewater treatment and disposal system to serve a 150 seat restaurant. In the Application Mr. Vail sought a permit for a system which was to have a design flow of 7,500 gallons per day based on 50 gallons, per seat, per day water usage. An employee of the Department wrote a memorandum dated May 5, 1985, recommending approval of the Application. The Department determined, however, that the size of the property on which the Inn was to be located was not large enough for the drain field necessary to accommodate a 150 seat restaurant. Therefore, Mr. Brown modified the proposed system and resubmitted application data indicating that a 108 seat restaurant would be constructed. The design flow of the new proposal was 2,160 gallons per day based on 20 gallons per seat per day. Mr. Brown had requested that the Department approve a system based upon the newly submitted design flow. The Department and Mr. Brown both agreed that this design flow was adequate; that it was reasonable to anticipate and provide for the treatment and disposal of a maximum of 2,160 gallons per day design flow. The effect of reducing the design flow and the number of seats was to allow a shortened drain field which could be accommodated by the size of the property the Inn was to be located on. On June 27, 1985, Mr. Vail arranged for a notice to be published in the Apalachicola Times. That notice provided, in pertinent part, the following: State of Florida Department of Environmental Regulation Notice of Proposed Agency Action on Permit Application The department gives notice of its intent to issue a permit to Jack Vail to construct a restaurant and on-site wastewater treatment and disposal system [sic] at Franklin Boulevard and Pine Avenue, St. George Island. The treatment consists of grease trap, septic tank, and sand filter followed by disposal into a drainfield. The project meets applicable standards and will not impair the designated use of the underlying ground water. There is no anticipated impact on surface waters or air quality. . . . . This notice was sent to Mr. Vail by the Department and he made arrangements for it to be published. Nowhere in the notice is it indicated that the system to be approved by the Department is for anything other than a restaurant. On July 11, 1985, less than four months after the Application was filed with the Department, the Department issued Permit Number DO19-101251 (hereinafter referred to as the "Permit"). In the cover letter sent with the Permit the Department indicated that the Permit allowed Mr. Vail "to construct and operate a 2,160 gallon per day, on-site wastewater treatment and disposal system serving St. George Inn Restaurant. . . ." The Department also indicates in the Permit that it is for the "St. George Inn Restaurant." The Permit also provides, in pertinent part, the following with regard to the purpose of the Permit: The above named applicant, hereinafter called Permittee, is hereby authorized to perform the work or operate the facility shown on the application and approved drawing(s), plans, and other documents attached hereto or on file with the department and made a part hereof and specifically described as follows: Construct and operate a 108 seat restaurant with an on-site wastewater treatment and disposal system. Wastewater flows shall be a maximum of 2,160 gallons per day generated by domestic facilities and kitchen wastes . . . Construction shall be in accordance with application dated March 18, 1985 and additional information submitted April 29, 1985, specifications and other supporting documents prepared by Brown and Associates and certified by Benjamin E. Brown, P.E. and submitted to the Department on June 5, June 17, and June 20, 1985. The Permit also contains the following "General Condition" number 2 and "Specific Condition" number 15: . . . . 2. This permit is valid only for the specific processes and operations applied for and indicated in the approved drawings and exhibits. Any unauthorized deviation from the approved drawings, exhibits, specifications, or conditions of this permit may constitute grounds for revocation and enforcement action by the department. . . . . 15. The Department shall be notified and prior approval shall be obtained of any changes or revisions made during construction. . . . . The Permit provides the following with regard to the effect of the conditions of the Permit: The terms, conditions, requirements, limitations, and restrictions set forth herein are "Permit Conditions", and as such are binding upon the permittee and enforceable pursuant to the authority of sections 403.161, 403.727, or 403.859 through 403.861, Florida Statutes. The permittee is hereby placed on notice that the Department will review this permit periodically and may initiate enforcement action for any violation of the "Permit Conditions" by the permittee . . . . During the week after the Permit was issued, Mr. Vail obtained a building permit from Franklin County for the construction of the "inn." In February, 1986, after construction of the Inn had begun, Department inspectors went to the construction site of the Inn. The Permit authorized this inspection and other inspections carried out by the Department. The Department determined that the Inn being constructed by Mr. Vail included a restaurant, an apartment on the third floor of the Inn with two bathrooms, and eight guest rooms on the second floor, each containing a bathroom. This was the first time that the Department knew that Mr. Vail's facility was to include guest rooms and living quarters in addition to containing a 108 seat restaurant. In March of 1986, the Department sent a warning letter to Mr. Vail notifying him of the violation of the General Conditions of his Permit: the use of the approved system for the treatment and disposal of wastewater from the ten bathrooms in the guest rooms and the two bathrooms in the apartment in addition to the 108 seat restaurant. On April 1, 1986, Department personnel met with Mr. Vail and Mr. Brown. The Department reminded Mr. Vail and Mr. Brown that the Permit requested and approved by the Department was for a 108 seat restaurant only. The Department had not authorized a system which was to be used for a 108 seat restaurant and ten additional bathrooms. Pursuant to General Condition 14, the Department informed Mr. Vail that it needed an engineer's evaluation of the ability of the system which had been approved to handle the additional flow which could be expected from the additional ten bathrooms. By letter dated April 1, 1986, the Department memorialized the meeting and indicated that Mr. Vail could operate a 100 seat restaurant and the apartment during the interim. By letter dated May 8, 1986, Mr. Brown asked for additional time to submit the evaluation requested by the Department. The Department approved this request by letter dated May 14, 1986. By letter dated May 16, 1986, Mr. Brown submitted an engineering evaluation which proposed modifications to the approved system to handle the additional ten bathrooms. By letter dated June 13, 1986, the Department indicated that the evaluation was generally acceptable" but requested additional information. In January, 1987, before the additional information was submitted, Mr. Brown died in an airplane accident. No evidence was presented to explain why the information requested by the Department in June of 1986 had not been submitted before January, 1987. In March, 1987, the Department inspected Mr. Vail's facility again. In April, 1987, the Department informed Mr. Vail that the Department would take action to revoke the Permit. Before the Administrative Complaint was issued, the Department requested that certain information be provided on behalf of Mr. Vail by an engineer in an effort to resolve the dispute. Mr. Vail did not, however, obtain the services of an engineer. Instead, Mr. Vail sent the Department information purporting to show the amount of water which had been used at the Inn. That information failed to prove the ability of the system that the Department had approved to handle the maximum wastewater which could be expected from maximum use of the 108 seat restaurant and ten additional bathrooms. At best, the information submitted by Mr. Vail is partial proof that the system is capable of handling the wastewater that has been generated at the Inn for the period of time for which the information relates. No competent substantial proof has been submitted to indicate that the system is capable of handling the maximum wastewater flows which may be experienced or even that the system is adequately handling the current flow. All that has been proved is that there is no apparent problem with the system in handling the current flow. In September, 1987, the Department issued the Administrative Complaint. Pursuant to this Complaint, the Department has sought the revocation of the Permit and prescribed certain orders for corrective action. No application has been submitted by or on behalf of Mr. Vail to the Department to construct and operate a wastewater treatment facility designed to accommodate the sewage flows which may be generated by the Inn as it has been constructed. Although the Department of Health and Rehabilitative Services and other agencies were aware that the Inn includes a restaurant and guest rooms, the Department was never so informed.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department issue a Final Order requiring that Mr. Vail comply with all of the corrective orders, except Paragraph 18, contained in the Administrative Complaint.

Findings Of Fact Respondent HDR has applied to DER for a permit to construct a 60,000 gallon per day extended aeration sewage treatment plant with percolation ponds. The facility would be used to provide secondary treatment of domestic waste from the HDR Mobile Home Park. The project is in Volusia County south of the City of Oak Hill and north of the Town of Edgewater. It is bounded on the east side by the Indian River and the west side by U.S. Highway One. The mobile home project site consists of approximately 156 acres, with the proposed wastewater treatment plant located in the southwest corner of the tract. HDR submitted Application No. 85433 to DER on July 2, 1984, requesting a permit to construct a 0.6 MGD extended aeration sewage treatment plant and associated percolation ponds for the mobile home project. Supplemental information was filed with DER on August 29, 1984. DER issued a notice of intent to permit the project on November 8, 1984. The plant would provide secondary treatment of effluent with a minimum of 90 percent removal of BOD's and suspended solids through aeration, settling and chlorination processes. The system is designed to collect sewage through a gravity system and lift station. The lift station dumps the sewage into the aeration chambers where forced air is mixed with the sewage, resulting in removal of organic materials and solids. The dissolved solids are then separated in the settling tank. From the settling tank, clear effluent enters the chlorine contact chamber where chlorine disinfectant is added prior to discharge into the percolation pond. The method of treatment described above and the design of the plant are standard. If the plant is operated properly, the wastewater will meet all DER criteria for secondary sewage treatment. Plant odor will be minimized by the continual feed of forced air into the system. Silencers will be installed on blowers to minimize any adverse noise effects from the blowers' operation. Aerosol drift is not a factor with the design of this plant. Security lighting will be provided, and the plant site will be surrounded by a six foot security fence. The design provides for effluent sampling access points and there will be a flow meter for measuring effluent discharge on site. A Class C operator will be required to operate the plant. Disposal of the 90 percent treated effluent will be made into two percolation ponds. The ponds will be alternately loaded, with one pond being loaded for seven days and then resting seven days. The total surface area for the two ponds is approximately 130,000 square feet. The ponds are designed with berms of three feet with an emergency overflow one foot from the top of each berm. The two ponds together are designed to handle 200,000 gallons per day which would be the ultimate build out of this project. However, the maximum capacity of the initial phase of the wastewater treatment plant would be 60,000 gallons a day. Any expansion to the sewage treatment plant would require a separate permit. The overall elevation of the area where the ponds are to be located is approximately 14 feet above sea level. Each pond is designed so that the pond bottom is two feet above the underground water table level measured at the highest point for the rainy season. In a 100 year flood, it is expected that the effluent and water can be absorbed without an overflow. The mobile home park has a storm retention system in which any theoretical overflow would be caught. The soil type at the location of the percolation ponds consists of several layers of sands. This type of soil has good permeability in that it provides a good transfer of water through the soil and is therefore suitable for siting of the percolation ponds. Pond design is conservative in that the hydraulic loading rate has a safety factor of at least 300 percent. Once the effluent has percolated into the ponds, the discharge will meet or exceed the level of quality of the G-2 ground water within the 100 foot zone of discharge. The design of the wastewater treatment plant also includes sufficient monitoring wells and provides for adequate buffer zones from residences and drainage ditches. No surface waters of the state are located within 500 feet of the sewage treatment plant or its percolation ponds. The Indian River, which is adjacent to the Hacienda Del Rio project, is approximately 2,500 feet from the sewage treatment plant. There will be no direct discharge by the sewage treatment plant into this body of water or any surface waters, nor would any indirect effect on surface waters be measurable. Shellfish harvesting is a local industry. The waters of the Indian River immediately east of the Hacienda Del Rio property are designated Class II waters suitable for shellfish harvesting. The Indian River is also part of the Canaveral National Seashore Waters, which are designated as Outstanding Florida Waters. Concern was expressed that additional growth in the area might contribute to degradation of these Class II waters. There was, however, no evidence to indicate that the construction or implementation of the wastewater treatment plant by HCD would degrade ore pollute the Indian River (which is both Class II and Outstanding Florida Water) or any other State of Florida surface waters. It should be noted that waters north and south of the property in the Indian River are closed to shellfish harvesting, apparently due to pollution. The Town of Edgewater north of the Hacienda Del Rio project has a secondary wastewater treatment plant which discharges its effluent directly into the Indian River. The City of Oak Hill to the south of the project has no wastewater treatment plant whatsoever. Individual businesses and homes utilize septic tanks, which can cause pollution to the Indian River through seepage. The HDR sewage treatment plant would thus meet higher standards than neighboring community facilities.
Recommendation From the foregoing, it is RECOMMENDED that the Department of Environmental Regulation issue a Final Order granting the application of Hacienda Del Rio.

Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant findings of fact are made: The Tamaron wastewater treatment facility (facility), located at 3800 Gatewood Drive, Sarasota, Florida, serves the Tamaron residential subdivision which was originally developed by U. S. Homes Corporation in 1976. The subdivision presently consists of 499 homes and was completely built out in the mid-1980's. The facility was originally owned and operated by U. S. Homes Corporation. Tamaron Utilities, a nonprofit entity comprised of the 499 homeowners, acquired the facility in November, 1987. At that time, the facility's existing operating permit was transferred to Tamaron Utilities. The facility is overseen by an elected board of volunteer homeowners. The Department is the agency of the State of Florida that is authorized to regulate domestic wastewater treatment and disposal facilities and permit their construction and operation. It is the successor agency to the Department of Environmental Regulation. By letter dated November 10, 1987, the Department notified Tamaron of the requirements of Chapter 87-303, Laws of Florida (Grizzle-Figg Amendment), which amended Section 403.086, Florida Statutes, and of the Department's intention to modify Tamaron's operating permit to incorporate a schedule of compliance with Section 403.086, Florida Statutes, as amended by Chapter 87-303, Laws of Florida. On August 23, 1988, an operating permit (D058-141783), which contained secondary water treatment requirements, was issued to the facility. Specific condition 7 of the permit required that the facility be in compliance with the Grizzle-Figg Amendment by October, 1990, or eliminate discharge to surface waters. On September 5, 1990, Tamaron filed an application with the Department to renew its domestic waste water treatment and disposal systems operation permit. Tamaron did not consider its facility as discharging waste into one of the specifically named water bodies set forth in the Grizzle-Figg Amendment or to "water tributary thereto" and thereby required to meet the advanced waste treatment criteria set forth in the Grizzle-Figg Amendment. However, in an abundance of caution, Tamaron proceeded to bring its facility into compliance with the advanced waste treatment criteria as set forth in the Grizzle-Figg Amendment. After numerous requests for additional information and several meetings between Tamaron and the Department, the Department issued its Notice of Permit Denial on April 9, 1991, asserting that Tamaron had not provided: (a) reasonable assurance that the requirements of Section 403.086(1)(c), Florida Statutes, mandating advanced waste treatment (AWT) before discharge to certain designated surface waters, would be met and; (b) reasonable assurance that the discharge to those certain designated surface waters would result in minimal negative impact as required by Section 403.086(5)(a), Florida Statutes. The facility continues to operate under its secondary treatment permit No. DO58-141783. The facility consists of a wastewater treatment plant designed for secondary treatment, with tertiary filtration. The design capacity of the facility is 155,000 gallons per day (0.155MGD) with actual flows of slightly over 100,000 gallons per day (0.100MGD+). Three percolation ponds surround the facility comprising the primary effluent disposal method for the facility. The Tamaron subdivision has a series of excavated surface water bodies (stormwater lakes), hydraulically connected, which eventually discharge at the northeast corner of the subdivision into Phillippi Creek. The direct path of surface water flow is from the subdivision's stormwater lakes to Phillippi Creek. These stormwater lakes are in multiple ownership. Under Department policy, stormwater systems permitted by the Department, its predecessor DER, or a water management district solely as stormwater treatment facilities under Chapter 17-25, Florida Administrative Code, are not considered "waters of the State". However, stormwater systems built prior to Chapter 17-25, Florida Administrative Code, permitting requirements, were considered "waters of the State" if they discharge more frequently than a twenty five year, twenty-four hour storm event. See Petitioner's exhibits 13 & 15. Tamaron's stormwater system was built prior to Chapter 17-25, Florida Administrative Code, permitting requirements, and was designed to discharge at a ten year, twenty-four hour storm event which is more frequent than a twenty five year, twenty-four hour storm event. Discharge of water into Phillippi Creek from the subdivision's stormwater lakes is fairly frequent; however, the volume of the discharge is low. Phillippi Creek is a natural surface water which eventually flows into Roberts Bay. Roberts Bay is a specifically named water body in the Grizzle-Figg Amendment (Section 403.086(1)(c), Florida Statutes). Since September, 1989, Tamaron has retained William Murchie, P.E. of AM Engineering, to evaluate the design and operation of the facility in order to comply with appropriate regulatory requirements. The facility provides biological treatment through a contact stabilization utilizing an activated sludge. This process typically provides high quality advanced secondary biological treatment. A chemical feed tank system utilizing ferrous sulfate was added to the facility several years ago to chemically precipitate out total phosphorus to meet the advanced waste treatment requirements. High-level disinfection is achieved in the large chlorine contact chamber and through two tertiary filters. At the design flow of 0.155MGD, the chlorine contact chamber provides nearly 80 minutes of contact time, while actual contact time for existing flows, not including time in filters, is calculated at 110 minutes. Upon leaving the chlorine contact chamber and the biological treatment components of the facility, the chlorinated effluent is directed through two tertiary filters to reduce the biochemical oxygen demand (BOD) and total suspended solids (TSS). After the tertiary filters, the effluent passes through the sample block where it is sampled for TSS, BOD and chlorine and is then piped sequentially into the first, second and third percolation ponds. The percolation ponds span two acres and provide residence time of 35 to 45 days, during which time the effluent is further biologically treated and nitrogen is reduced. From the percolation ponds, the effluent is pumped into a low pressure system which uniformly distributes effluent over two nitrogen reduction filters. The nitrogen reduction filters are located north of the plant and are immediately adjacent to one of the subdivision's stormwater lakes. The nitrogen reduction filters consist of deep sand beds covered with Bermuda grass to provide high nitrogen uptake. The irrigation of the two nitrogen reduction filters is alternated every half day. These nitrogen reduction systems were modified in October/November, 1990, by adding 3 to 3 1/2 feet of clean sand with a permeability rate of 28 feet per day, planting Bermuda grass, and installing an irrigation/distribution system. These filters replaced two sand pits with shallow layers of very coarse sand, after initial testing demonstrated the sand pits to be inadequate in removing nutrients consistent with statutory requirements. In January, 1992, an underdrain system utilizing perforated pipe was installed in the nitrogen reduction filters to create an aerobic zone and to provide a representative sample port after nutrient reduction in the filters. This sample port, used for the biweekly monitoring, consists of a single solid pipe, that collects effluent from the perforated pipes, with a tap to prevent discharge into the adjacent stormwater lake, except during sampling events. The biweekly sampling event results in effluent being discharged from the pipe for approximately 30 minutes to flush the pipe so as to get a proper sample. The underdrain sampling port at the nitrogen reduction filters replaced two earlier monitor wells between the nitrogen reduction filter and the stormwater pond, which proved ineffective because of their location. The perforated underdrains are situated in filter bed sand of medium grain size with a permeability rate 100 feet per day and located below 3 - 3 1/2 feet of clean sand with a permeability rate of 28 feet per day and above very permeable layers of sand, stone and coarse shell. (See Tamaron's exhibit 23 and Department's exhibit 14) The very permeable layers of sand, coarse shell, the perforated pipe and the single solid pipe are all located above the ground water table. Since the perforated pipe and sample port are both located above the ground water level and the surface of the adjacent stormwater lake, it is unlikely that the effluent sample taken from the sample port would be influenced by the ground water or a back flow of water from the adjacent stormwater lake. The coarse shell layer situated below the nitrogen reduction filters extends to the edge of the adjacent stormwater lake. Therefore, the effluent, other than the effluent trapped in the perforated pipe and carried to the sample port, that is irrigated onto the nitrogen reduction filters passes through the sand and into the coarse shell layer. The effluent is then transported laterally through the coarse shell layer to the underground edge of the adjacent stormwater lake where there is a subsurface discharge into the adjacent stormwater lake. Since the discharge to the stormwater lakes is primarily subsurface in nature, the logical compliance point to measure effluent parameters would be the underground sample port which collects the effluent prior to subsurface discharge into the stormwater lake. See Petitioner's exhibit 15. The direction of ground water flow at the facility is towards the north to the adjacent stormwater lakes as evidenced by the hydraulic gradient of the site determined using ground water table elevations. The location for sampling effluent from the facility for compliance with secondary standards was described in Specific Condition 5 of Tamaron's previous permit No. D058-141783 dated August 23, 1988. Specific Condition 5 states that the discharge from the chlorine contact chamber shall be sampled in accordance with Chapter 17-19, Florida Administrative Code, (now Chapter 17-601, Florida Administrative Code), for compliance with the stated secondary limits. The facility's tertiary filters are located after the chlorine contact chamber. Tamaron samples effluent for compliance with secondary standards (BOD,TSS, chlorine) at the sampling box after disinfection and tertiary filtration. Tertiary filtration is designed to achieve a more efficient removal of TSS and BOD. The resulting effluent is usually of higher quality than secondarily treated effluent. A secondary plant with tertiary filtration is referred to as an "advanced secondary treatment" plant. Data presented by Tamaron titled Tamaron 1991-1993 Data On FDER Permit Compliance (Tamaron's exhibit 17, page 1 of 2) shows reported values, sampled after tertiary filtration at the sample box, which suggest that secondary treatment parameters, including fecal coliform, are not being exceeded. The data actually shows a very high removal rate for the parameters sampled. The United States Environmental Protection Agency issued a National Pollutant Discharge Elimination System (NPDES) permit, number FL0042811, to Tamaron for the facility with an effective date of June 1, 1991, which authorized Tamaron to discharge from the facility to the receiving waters named Phillippi Creek to Roberts Bay in accordance with the effluent limitation, monitoring requirements and other conditions set forth in the permit. Since the facility was located in the Grizzle-Figg Amendment area of Florida certain changes were made from the draft permit to the final permit. Those changes appear in the Amendment To The Statement Of Basis At The Time Of Final Permit Issuance which is made a part of the final permit. The amendment provides for changes in Part I, Effluent Limitations and Monitoring Requirements. These changes, among other things, require that the Grizzle-Figg Amendment annual limits of 5 mg/l BOD, 5mg/l TSS, 3mg/l total nitrogen and 1mg/l total phosphorus be added to the effluent limits to adequately maintain water quality standards, and added monitoring requirements and measurement frequency regulations to give the basis for permit limits and conditions in accordance with Chapters 17-302, 17-600 and 17-601, Florida Administrative Code. Data presented by Tamaron titled Tamaron 1991-1993 Data On NPDES Permit Compliance (Tamaron's exhibit 17, page 2 of 2) show reported values sampled after nitrogen reduction filters which suggest that the maximum values for AWT parameters, including fecal coliform, are not being exceeded, particularly after January, 1992, when Tamaron began sampling effluent collected by the perforated underdrains at the sample port. Tamaron has been monitoring and reporting compliance under its final NPDES permit and providing copies to the Department. There was no evidence that Tamaron was ever in violation of its NPDES permit. Tamaron submitted documentation to the Department with its permit application that demonstrated high-level disinfection within the facility was being achieved. However, TSS was being sampled after the application of the disinfectant. Using this procedure, the facility continued to achieve high- level disinfection until the permit denial. After the permit denial, the facility resumed basic disinfection which was required under Tamaron's permit for secondary treatment. This same data indicates that there was compliance with the requirements for fecal coliform. The record is not clear as to the frequency and number of samples taken to provide the data for reporting compliance with the NPDES permit and the data presented in Petitioner's exhibit 17, page 2 of 2. However, there was no evidence, other than sampling for TSS after the disinfectant was added, that Tamaron was not complying with its NPDES Permit that required, among other things, that the monitoring requirements and measurement frequency of the Department's rules and regulations be followed by Tamaron. Tamaron has modified and upgraded the facility in order to achieve a treatment process which will produce effluent of a quality for discharge under the Grizzle-Figg Amendment. Tamaron has provided reasonable assurances, although not absolute assurance, that the facility can comply with the discharge permit requirements of Chapter 403, Florida Statutes, including Section 403.086, Florida Statutes, notwithstanding the testimony of Jay Thabaraj to the contrary concerning Tamaron's sampling technique and its method of obtaining high-level disinfection which can be addressed as a specific condition, if necessary. Studies conducted by the Tamaron's engineer included in Petitioner's exhibit 21 indicates that there was no adverse impact to the stormwater lakes from the facility's wastewater treatment and disposal system. Tamaron has provided reasonable assurances that the point of discharge is a reasonably access point, where such discharge results only in minimal negative impact.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Department enter a final order granting Tamaron an operating permit for its facility as secondary treatment facility. In the alternative, that the Department enter a final order granting Tamaron an operating permit for its facility that requires compliance with the advanced waste treatment criteria set forth in Section 403.086(4), Florida Statutes, that, in addition to any general or specific conditions that are normally required, contains specific conditions that: (a) contains specific instructions on sampling technique, sampling frequency and reporting as set forth in Rule 17- 740(1)(b)2., Florida Administrative Code, and (b) sets forth compliance with high-level disinfection, with a time limit for compliance, that accomplishes the intent of the rule, if not the strict letter of the rule, without total redesign of the facility.

Findings Of Fact The Respondents, Frank L. Reppa and Denise J. Reppa, own and reside in their dwelling located at 3863 Plumosa Drive, St. James, Florida. The property is a narrow canal front lot. All lots in the area are small and narrow and the dwellings thereon, mostly mobile homes, are placed closely together. On January 11, 1988, as the result of a nuisance complaint by the Reppa's next door neighbor, Stephen E. Havig, an Environmental Specialist with the Lee County Health Department, a part of the State of Florida DHRS, inspected the property in question and observed that effluent from the Respondents' drain field, a malodorous liquid, had run from Respondent's property down onto the driveway of their neighbors. On January 13, 1988, he returned to the property and spoke with Mrs. Reppa who admitted to living on the property. He again observed that the drain field in the Reppas' septic system was heavily saturated and had failed. Effluent was coming to the surface due to the high water table resulting from heavy recent rains and the failure of the system, and there was still a sewage odor to the effluent. The effluent showed in stains on the neighbor's drive. Mr. Havig told Mrs. Reppa that the problem had to be corrected as it was a violation of the law to allow it to remain. In response, Mrs. Reppa indicated they had no money to effect the repairs and because of that, Mr. Havig, who could have cited them immediately, indicated he would return to his office to see if they could be given some additional time to have the work done. After checking with his supervisor, Mr. Havig, on the same day issued an "Official Notification of Insanitary Nuisance" and a "Notice of Intended Action", both of which were sent by Certified Mail and receipted for by Mrs. Reppa on January 19, 1988. The Notice gave the Reppas until January 28, 1988 to correct the problem. On January 14, 1988, Mr. Havig again talked with Mrs. Reppa, telling her what he was sending and advising her how she could get the problem fixed. When he again went out to the property on January 28, 1988, he noted that the property had dried out due to a lack of rain. However, he could see no evidence that any repairs had been effected. He returned to the property on February 1, 1988 after a rain and observed that the problems had reoccurred. Mr. Havig again spoke with Mrs. Reppa on February 8, 1988, at which time she advised him the problem was to be repaired, but they were without funds to pay for it. At that time, Mr. Havig gave the Reppas three weeks to have the work completed with a contractor to be retained within one week. When he spoke with Mrs. Reppa on February 16, 1988, she stated she was still having trouble getting a contractor. She had contacted one contractor who looked at the system on February 15, 1988 and who proposed to remove the washing machine from the drain system. When Mr. Havig talked with Mrs. Reppa on February 19, 1988, she indicated she would have to discuss the matter with her husband. Mr. Havig stated at that time that the Department would have to proceed with enforcement action if work was not started on the correction by February 22, 1988. No corrective action was taken by the Reppas and the Administrative Complaint was filed as a result. DHRS considers it important to properly dispose of effluent because, since it contains human waste, it carries bacteria, viruses and a danger of parasites. Agency policy requires that the septic system be continually monitored and that the tank be pumped and the drain field be repaired when necessary. The Department has no funds available to assist those who cannot afford to make repairs. In order to be properly processed, effluent drainage from septic tanks needs a minimum of two feet of soil between the discharge outlet of the tank and the water table. The soil acts as a filter to remove harmful organisms and contaminants from the effluent before it reaches the water table. A high water table, due to heavy rains or other causes, prevents this filtration and causes the effluent to come to the surface. The situation is correctable. Two methods of correction are: 1) elevate the system above the water table, or 2) remove the saturated soil and replace it with a good grade of sand. In October, 1985, another complaint against the Reppas, relating to the same situation, was filed with DHRS. At that time, the Reppas paid $650.00 to have the system repaired by an individual who replaced the drain field, drawing it away from adjoining property and toward the road. Though the contractor assured them this would fix the problem, wash water would continue to come to the surface. As a result, Mrs. Reppa has refrained from washing clothes at her home and takes them to the laundry in town. Because of the actions they have taken, such as having the drain field expanded and moved, the pumping out of the septic tank in January, 1988, and the cessation of washing clothes at home, Mr. and Mrs. Reppa are convinced the system is not overflowing and that the water on the neighbor's property is the accumulation of surface water drainage when it rains. The Reppa property is higher than the neighbor's property and Mrs. Reppa believes that rain water drains down there. The new part of the drain field works and the water in question, she feels, cannot be effluent. The evidence of record, however, indicates to the contrary and that it is waste effluent. Inquiry by the Reppas indicates that it would take $750.00 more to fix the system and the Reppas do not have that money. They are still paying back the money they borrowed from Mrs. Reppa's parents to make the first repairs. Mr. Reppa is a commercial fisherman whose income has been substantially reduced due to the restrictions placed on the taking of redfish. Many neighbors in the area, according to the Reppas, discharge sewage directly into the abutting canal and allow wash water to run out onto the ground. The Reppas cannot comprehend why these individuals, mostly three month winter visitors, are not cited while they, full time residents, are.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is, therefore: Recommended that an administrative fine of $50.00 per day be assessed against the Reppas for the violation established, said fine to be effective upon entry of a Final Order herein, with provision that the fine be remitted upon satisfactory proof that the violation has been corrected. Recommended in Tallahassee, Florida this 24th day of August, 1988. ARNOLD H.

Findings Of Fact During 1990, Respondent/Applicant, City of Lynn Haven, filed several applications with the Respondent, Department of Environmental Regulation, seeking the issuance of several permits to build a wastewater collection system and a two million gallon per day advanced wastewater treatment (AWT) plant. The proposed facility is intended to replace the wastewater treatment facility currently being used by the City of Lynn Haven. After a review of the applications the Department proposed several Intents to Issue covering the different aspects of the proposed projects. The Intents to Issue included: A) a variance and dredge and fill permit, pursuant to Sections 403.201, 403.918, 403.919, Florida Statutes, and Rule 17-312, Florida Administrative Code, authorizing a subaqueous crossing of North Bay (Class II waters) and installation of a force main (permit #031716641), B) a collection system permit, pursuant to Chapter 403, Florida Statutes, and Rules 17-4, 17-600 and 17-604, Florida Administrative Code, for the installation of approximately 11 miles of pipe from North Bay to the proposed treatment plant, C) a dredge and fill permit #031785181, pursuant to Sections 403.918, 403.919, Florida Statutes, and Rules 17-4, 17-312, Florida Administrative Code, authorizing 10 incidental wetland crossings associated with the collection system, and, D) a construction permit #DC03-178814, pursuant to Chapter 403, Florida Statutes, and Rules 17-4, 17-302, 17-600 and 17-611, Florida Administrative Code, authorizing the construction of a 2.0 mgd wastewater treatment plant. Sand Hill Community Improvement Association challenged the Department's Intents to Issue. The Sand Hill Community Improvement Association (Sand Hill) is an association composed of 74 formal members plus numerous supporters. Both members and supporters are residents who live near the site of the proposed Lynn Haven sewage treatment plant. They are sufficiently close to the plant site that construction of the proposed project could impact their property. The members are very concerned about any threat of pollution to the aquifer from the proposed plant since all of the members are dependent on private wells for their drinking water. Additionally, members of the association use the proposed site, as well as the associated wetlands, Burnt Mill Creek and the nearby lakes, for a variety of recreational purposes, including hunting, fishing, hiking, bird-watching, boating and swimming. Given these facts, the Association has standing to challenge the Department's Intents to Issue involved in this case. The City of Lynn Haven is located on a peninsular section of the south shore of North Bay and, except for its connection to the land, is surrounded by environmentally sensitive Class II or Class I waters. Lynn Haven's existing wastewater treatment plant was poorly designed, has not worked properly, and is old and outdated. The plant is permitted to treat up to 950,000 gallons per day. However, the existing plant is currently exceeding its originally permitted treatment limits and is treating in excess of 1,200,000 gallons per day. The sewage only receives secondary treatment, Secondary treatment is the minimum state standard for wastewater treatment. The secondarily treated wastewater is pumped several miles to a spray irrigation site located in the eastern portion of the City. The sprayfield site has never worked properly due to a high groundwater table and a confining layer of soil, both of which prevent the effluent from percolating into the ground. Because the sewage effluent cannot percolate into the ground, the existing operation frequently results in direct runoff into a ditch which empties into North Bay, a Class II waterbody. Such discharge of wastewater effluent into Class II waters is prohibited by Department regulations. 1/ At this time, the existing wastewater treatment facility is in violation of both DER and EPA standards and is under enforcement action by both agencies. The existing facility is currently operating without a permit and the Department has advised Lynn Haven that the existing facility as it now operates can not be permitted. In fact, all the parties agree that the City is in serious need of a wastewater treatment facility which works and does not pollute the environment. However, the parties disagree over the method by which proper wastewater treatment could be accomplished by Lynn Haven. Since 1972, the City, through various consultants and with the aid of DER, has reviewed approximately 40 alternatives for wastewater disposal. After this review, the City of Lynn Haven selected the alternative which is the subject of this administrative hearing. The alternative selected by the City of Lynn Haven consists of the construction of a proposed advanced wastewater treatment (AWT) plant and distribution system. The new plant will be on a 640 acre parcel of property located approximately 12 miles north of Lynn Haven. The location of the new plant will necessitate the rerouting of the wastewater from the old plant to the new plant by construction of a new transmission line approximately 12 miles north of the City across North Bay and parallel along State Road 77. 2/ The treatment process proposed for use in the new AWT plant is known as the AO2 process. The process is patented. The AO2 treatment process primarily consists of biological treatment with settling and filtration. The treatment process also includes a chemical backup treatment to further reduce phosphorus if necessary. The evidence demonstrated that this type of facility has been permitted by the Department in at least five other wastewater facilities throughout the state. The treatment facility will have a two million gallon per day, lined holding pond on site for the purposes of holding improperly treated wastewater for recirculation through the proposed facility. Any excess sludge generated by this treatment process would be routed to lined, vacuum-assisted, sludge drying beds. The sludge would then be transported offsite to a permitted landfill for disposal. The evidence demonstrated that this treatment process would not produce any objectionable odors. Once the wastewater is treated, it will be disinfected by chlorination to eliminate pathogens. The chlorination process is expected to meet state standards. After chlorination, a dechlorination process would occur to remove any chlorine residuals which would have a harmful affect on the environment. The treated wastewater would then be re-aerated and discharged through the distribution system indirectly into a wetland located on the 640 acre parcel of property. The quality of the treated wastewater is expected to meet the advanced wastewater treatment (AWT) standards. These standards are five milligrams per liter total suspended solids (T.S.S.), five milligrams per liter BOD, three milligrams per liter nitrogen (N), one milligram per liter phophorus (P). Ph will be in the range of six to eight units on an average annual basis and can be adjusted up or down if necessary to meet the ph levels of the ecology into which the wastewater ultimately flows. This effluent quality is approximately five times cleaner than secondarily treated effluent. Additionally, as a condition of the draft permit, the proposed facility would be operated by a state-licensed operator and would be routinely monitored to insure that the treated wastewater effluent meets advanced wastewater treatment standards. Given these facts, the evidence demonstrated that the applicant has supplied reasonable assurances that the plant will perform as represented and that the effluent will meet the state standards for advanced wastewater treatment. As indicated earlier, the site for the proposed AWT plant contains approximately 640 acres and is located approximately 12 miles north of Lynn Haven in an area known locally as the Sand Hills. The City specifically purchased this parcel of property for the construction of the proposed wastewater treatment plant. The plant itself would be located in the northeast corner of the property. The 640 acre site was previously used for silviculture. The entire area is currently planted in pines except for a low area that is dominated by a pristine, woody wetland system of titi. The titi wetland is approximately 212 acres in size and generally runs through the center of the property from the northeast to the southwest. The wetland is low in acidity, with an estimated ph between 4 and 5. The site consists of hilly, mineralized soils. The soils within the forested wetland are organic in nature. Based on the evidence at the hearing, there does not appear to be any significant confining layers of soil which would prevent the treated wastewater from percolating in the soils and draining towards the wetland and ultimately into Burnt Mill Creek, a Class III waterbody. Once the effluent leaves the plant, it would go through a distribution system. The proposed distribution system will consist of six, 500 foot long, 12 inch diameter perforated pipes. Each 500 foot section of pipe has 100 one and one-half inch orifices which will discharge the treated effluent onto an eight foot wide concrete pad. This concrete pad will dissipate the effluent's energy, prevent erosion at the orifice site and insure that the effluent sheetflows onto and eventually into the sandy soils of the plant site and ultimately into the receiving wetland. The distribution pipes are located around the east, north and western portions of the receiving wetland and are variously set back from the receiving wetland approximately 80 to 200 feet. The distribution system is designed with valves to allow for routing of flow to different branches of the system if it is determined through long term monitoring that there is a need to allow for any of the receiving wetland to dry out. None of the distribution branches are located in any jurisdictional wetlands of the State of Florida. The receiving wetland will receive a hydraulic loading rate of approximately 1.8 inches per week once the new advanced wastewater treatment plant is operating at capacity. Both the surface waters and groundwaters on the 640 acre parcel flow from northeast to southwest across the property. The evidence clearly demonstrated that any treated wastewater discharged on the site would move down hill by surface or groundwater flows towards the wetlands in the central portion of the property and eventually discharge into Burnt Mill Creek located at the southwest corner of the parcel. The evidence demonstrated that it would be highly unlikely for the surface or groundwater to move in any other direction and would be unlikely for the surface or groundwater to move towards any residents located to the north or east of this parcel. Evidence of the topography and its relatively sharp gradient clearly demonstrated that the treated wastewater discharged in the northeast corner of this site would not result in any significant still water ponding and would exit the site at the southwest corner of the property in approximately 14 hours. The evidence did demonstrate that, depending on the wetness of the weather, there may likely be certain times of the year when a flowing type of ponding would occur. However, this wet weather ponding was not shown to be of a duration which would impact to a significant degree on the flora and fauna of the area or increase the number of disease bearing mosquitoes in the area. As indicated earlier the treated effluent from the proposed AWT plant will flow into Burnt Mill Creek. Burnt Mill Creek will ultimately carry the treated wastewater approximately 11 miles down stream to North Bay. The City can directly discharge up to two million gallons per day of AWT water into Burnt Mill Creek without violating state water quality standards. Therefore, the volume of wastewater discharged into Burnt Mill Creek should not have significant impacts on surface and ground water quality. Moreover, Chapter 17-611, Florida Administrative Code, authorizes the discharge of up to 2 inches per week to receiving wetlands provided wastewater is treated to AWT standards. The evidence demonstrated that this rule was developed as an experimental effort to determine if wetlands could be appropriate areas for wastewater effluent to be either discharged or treated. These state limits were intended to be very conservative limits and were designed to insure that the impacts to receiving wetlands would be minimal. The evidence and testimony demonstrated that the receiving wetland system involved in this case should not be adversely impacted beyond those limits set forth in Section 17-611.500, Florida Administrative Code, for flora, fauna, macroinvertebrates, fish or vegetation and will meet all standards set forth in Chapter 17-611, Florida Administrative Code. However, it should be noted that the wetland/wastewater program is highly experimental and very little is known about the actual impacts of wetland/wastewater systems since facilities similar to the one proposed by Lynn Haven have not yet been placed in service. The evidence did show that there would be some long term impacts to flora and fauna in the wetland area primarily due to ponding, changed ph and the introduction of nutrients and pollution in the form of the effluent. However, the regulation does allow for some change within a receiving wetland and the evidence did not demonstrate that these changes would be significant or detrimental. Petitioners' own witness concluded that other deep wetland treatment systems are doing a very good job in meeting state water quality standards. Although Petitioners' expert noted potentially adverse impacts to flora and fauna from other wastewater treatment systems, these other systems were slow moving, impoundment-type systems that are not similar to the wastewater/wetlands system proposed by the City of Lynn Haven. The Lynn Haven system is designed for percolation and sheetflow, not ponding. Though there should be some expected changes, no evidence was provided that the receiving wetlands for the Lynn Haven facility would be affected to the extent there would be violations of any standard as set forth in Chapter 17-611, Florida Administrative Code. In essence, the legislature has determined that such experimentation with wetland areas is appropriate, albeit, even with the conservative limits of DER's rule, may prove to be a mistake. This facility is designed to fit within that rule and in fact is probably the best technology available for use in a wetland/wastewater situation. Finally, in order to avoid any potential impacts on the area which may over time become significant an approved monitoring program for surface water quality and affects on flora and fauna, as well as a groundwater monitoring program are required as conditions of the permit. The groundwater monitoring program has been designed to monitor any potential long term impacts to groundwater. With these protections there should not be any significant adverse impacts to surface or groundwater quality and the applicant is entitled to a construction permit for the AWT plant and distribution system. Lynn Haven's sewage would reach the proposed AWT plant through a transmission line. The transmission line would run from Lynn Haven's existing wastewater treatment plant across North Bay and through the unincorporated area of South Port. The Southport area is not sewered and utilizes individual septic tanks for its sewage. The transmission line would be constructed entirely in state road right-of-way. The line would terminate at the 640 acre site described above. A new, variable speed pumping station would be constructed adjacent to the old wastewater treatment plant. From this pump station, a 24 inch line would be constructed on City right-of-way up to the south shore of North Bay. At this point, the transmission line would be reduced in size to 20 inches and would be embedded approximately three feet below the Bay bottom. An additional variable speed pumping station would be located approximately half way along the 12 mile route of the transmission line to insure adequate pressure to pump wastewater to the new wastewater treatment plant. The pumps are to be employed to insure that the wastewater is continuously pumped uphill to the new site so that waste does not set, become septic, and create odor problems. The pumps are equipped to provide for chemical control of odor if necessary. Also, as a condition of the permit, the pumping stations are required to have backup power supplies should power be lost to the stations. The pumping stations and backup power supplies are to be tested monthly and the pumps are required to be continuously monitored by radio telemetry to insure they are operating properly. Additionally, the City of Lynn Haven will be required, as a condition of the permit, to visually inspect the entire length of the wastewater transmission line three times per day. The portion of the transmission line which would cross North Bay is approximately 3000 feet in length and would be constructed of high density polyethylene pipe (HDPE) with a wall thickness of one and one-half inches. HDPE pipe is used to transport materials such as hazardous wastes where leakage is not permissible. This type of pipe is virtually inert in that it is highly resistant to corrosion and other chemical reactions. It is also impact resistant and has a very high tensile strength. The pipe comes in 40 foot segments and is heat welded (fused) together. This type of joint significantly reduces the chance of any leakage. In fact, leakage around pipe joints is more likely to occur with other types of pipe and pipe connections. HDPE pipe is currently carrying wastewater across Watson Bayou in Bay County, Florida. 3/ There have been no reported problems with leaks or breaks occurring in the pipe crossing Watson Bayou. Given these facts, the probability of the proposed HDPE pipe leaking or breaking is extremely low, albeit not impossible, and such pipe appears to be the best material available for constructing a wastewater treatment transmission line across protected waters of the State. As a condition of the construction permit, the portion of the transmission line crossing North Bay will be required to have isolation valves at each end so that the pipe may be completely isolated in the event that it needs repair. The underwater portion of the line would be visually inspected by a diver twice per year and the line would be pressure tested before being placed into service. Additionally, pressure tests would be performed once a year. The construction permit also requires Lynn Haven to periodically inject dye into the proposed transmission line to check for any small leaks that may not otherwise be detected. Finally, the HDPE pipe would also be equipped so that television cameras could be inserted into the pipe to routinely inspect the interior of the pipe. In the event the HDPE portion of the transmission line would need to be repaired, the line could be immediately, temporarily repaired by a dresser coupling. A permanent repair could then be made in less than 24 hours once the material and equipment were staged at the site. The City intends to locally stockpile all necessary parts and equipment to effect any required repair to prevent any delay beyond four days. Permanent repairs would be accomplished by floating the line to the surface. The area needing repair would be cut out and a new section would be put in place by heat fusion. The line would then be pressure tested to insure the absence of leaks and placed back into service. During this process, the line would be taken out of service by the isolation valves and flow would be diverted to the eight million gallon holding ponds at the City of Lynn Haven's existing facility. These holding ponds can hold four days worth of wastewater from the City of Lynn Haven. Lynn Haven is required, as a condition of the construction permit, to have this reserve capacity as well as have a contractor on standby to make any repairs in the event such repairs are necessary. All of the technical specifications for the transmission system and the operating conditions imposed on it are designed to insure that the system does not fail or develop any leaks which could impact receiving waters, including North Bay. Given the permit conditions, the required inspections for leaks, the sound engineering design and quick repair methods proposed, the evidence demonstrated that the probability of any leak occurring in the portion of the transmission line crossing North Bay is extremely low and that if such a leak does occur any potential harm to the environment will likely be limited and quickly eliminated. The evidence demonstrated that the design of the transmission line and permit conditions provide reasonable assurances that the transmission line will meet or exceed the Department standards set forth in Chapter 17-604, Florida Administrative Code. Therefore, the applicant has provided reasonable assurances that the transmission line/collection system will not violate Department standards or rules and the applicant is entitled to a permit (permit #CS03-178910) for the proposed collection system. In addition to requiring a construction permit/collection system permit for the wastewater transmission line, the line will also require dredge and fill permits and a variance for crossing waters of the state. There are ten incidental crossings of state waters and one major crossing o f North Bay. Of the ten incidental crossings, two are over small creeks (Scurlock and Little Burnt Mill) These two incidental creek crossings will be accomplished by placing the transmission line (ductile iron pipe) on top of pilings placed in the water. Best management practices such as turbidity curtains and other erosion control practices are proposed and required by the permit to minimize construction impacts on water quality. The only impacts to wetland resources would be from the placement of the pilings. The evidence demonstrated that any impact would be minimal and not significant. The evidence did not demonstrate that the aerial crossings would have any long term water quality or environmental impacts. The remaining eight incidental crossings of waters of the state consist of small, seasonally wet ditches which would be traversed by trenching and burying the transmission line. Again, turbidity controls such as curtains and hay bales would be employed to protect water quality. The evidence did not demonstrate that any significant long term or short term impacts to resources of the state would occur. The evidence did demonstrate that the applicant has provided reasonable assurances that water quality standards would not be violated in regards to these 10 incidental water crossings. Likewise, the evidence demonstrated that the construction of these 10 incidental water crossings would not be contrary to the public interest. Therefore, the applicant is entitled to issuance of a dredge and fill permit (permit #031785181) for these 10 water crossing. However, a much harder question arises in relation to the dredge and fill permit and the variance required for the 3,000 foot segment of the wastewater transmission line which crosses North Bay. Pursuant to Rule 17- 312.080(7), Florida Administrative Code, permits for dredging and filling activity directly in Class II waters which are approved for shellfish harvesting by the Department of Natural Resources (DNR) shall not be issued. The reason for the rule is that any pollution caused by dredging and filling and, as in this case, the permanent placement of a sewage pipe in food producing waters could potentially have catastrophic effects on more than just the environment but on local employment in the shellfish industry and the quality of food available to the State. Put simply, the Department has determined by enacting its Rule that the public interest in food producing waters far outweighs any other consideration or criteria under Sections 403.918 and 403.919, Florida Statutes, in determining whether dredging and filling should take place in Class II, shellfish waters. In other words, it is not in the best interest of the public to allow dredging and filling so that a pipe carrying raw sewage can be placed in shellfishing waters. However, irrespective of this determination, the Department believes that, pursuant to Section 403.201(1)(c), Florida Statutes, it may grant a variance from its rules to relieve a hardship. As indicated earlier, North Bay is a Class II waterbody, conditionally approved for shellfishing. North Bay, therefore, falls within the Rule's prohibition against dredging and filling in Class II waters and the City is required to demonstrate the presence of a hardship in order to vary the Rule prohibition and obtain a dredge and fill permit for the North Bay crossing. On issues involving variances, the Department employs a two step analysis. The first part of the analysis is whether a hardship is present and the second is whether, if the variance were granted, would it result in permanent closure of Class II shellfish waters. The Department correctly recognizes that the question of whether a hardship exists is a question of fact and is determined on a case-by-case basis. Surprisingly, in a kind of "what we don't know can't hurt" posture the Department reviews a request for a variance standing alone based on the application as it is presented and does not require analyses of other possible alternatives to the granting of a variance. However, the existence of any alternatives, costs of any alternatives, timeliness of any alternatives, problems with any alternatives, whether an alternative represents a short term or long term solution to a given problem and the implementability of any of the alternatives are all factors utilized by the Department in determining whether or not to grant a variance. The Department's policy of non- review makes no sense, either factually or statutorily, when the Department is faced with varying a prohibition it created in its own rules. Similarly, the Department's policy of not requiring other alternatives to be examined before granting a variance goes against the fact that an applicant has the burden to establish entitlement to a permit and, in the case of a hardship variance, that a hardship exists because reasonable alternatives to granting a variance are not available. 4/ Likewise, the second part of the Department's hardship analysis relating to the permanent closure of shellfishing waters makes no sense given the fact that a non-permanent closure of shellfishing waters may have the same or just as serious effect on employment in the shellfishing industry, the loss of income due to an inability to earn a living in that industry and health risks posed by contaminated seafood. Temporary loss of income or a livelihood can, for all practical purposes, have consequences to the persons directly affected by a temporary closure of shellfishing waters similar in nature those caused by the permanent closure of shellfishing waters. The same can be said for health risks posed by a contaminated food supply. Rule 17-312.080(7), Florida Administrative Code, does not contain any exceptions for the temporary closure of shellfish waters. Nor is the rule limited to instances of permanent closure. Permanent closure is simpy not required in order to support a hardship under Section 403.201, Florida Statutes. Moreover, neither step in the Department's two-step analysis is included in any Rule promulgated by the Department. 5/ Without such a Rule, it is incumbent upon the Department or the applicant to demonstrate the underpinnings for this non-rule policy. No such evidence was presented at the hearing. In fact, the evidence presented at the hearing affirmatively demonstrated that the Department's non-rule policy violated both its own rules and the statute under which it is trying to proceed. As indicated, the issue of hardship is a question of fact and involves a weighing of all the facts and cicumstances involved in this project. In this case, there are shellfishing areas located close to the proposed location of the transmission line. North Bay is sometimes closed to shellfish harvesting by the Department of Natural Resources. These closures generally occur during wet weather conditions and are due to stormwater runoff and the failure of septic tanks in Southport. 6/ Additionally the current Lynn Haven system also contributes to the closure of North Bay. No competent, substantial evidence was provided that issuance of the permit and variance would result in the permanent closure of shellfish waters. The location of the proposed transmission line would be several hundred feet west of the Bailey Bridge embedded in the Bay floor. 7/ The proposed alignment of the transmission line through North Bay is in an area which is relatively biologically unproductive. The proposed placement of the transmission line avoids the few grassbeds that exist in the nearshore shallow areas except for approximately 200 square feet of grass. During construction of the line, these grasses would be removed immediately before the line is placed in a trench and then would be promptly replanted in the same area. The evidence demonstrated that the affected areas of grass should be able to reestablish itself. The evidence further demonstrated that there would not be any long term adverse impacts to these aquatic resources and there should not be any significant long term impacts on the balance of any aquatic life which may exist on the bay bottom. Water quality during construction will be protected by use of turbidity controls to control sediments. Therefore, any short term impacts on aquatic resources are likely to be insignificant. Concerns about long term adverse impacts to Class II waters are greatly reduced by the type of pipe and conditions in the permit which require that the transmission line be routinely inspected and tested to insure that there is no leakage and that in the unlikely event the line should need to be repaired, the line could be easily isolated and quickly repaired. The evidence showed that, to completely avoid Class II waters, the line could be moved several miles to the west or east of the line's proposed location or be placed over or under the Bay. If the line was moved west to the extent that it was in Class III waters, it would be over 40 miles long and would more than double the cost of the project. If the line was moved several miles to the east, it would go through the Deer Point Lake Watershed. The watershed is a Class I water supply for Bay County. Clearly, moving the line either west or east is not practical nor realistically feasible. Tunneling under North Bay would be very risky and is not technically feasible. The length of the tunnel would require steel pipe to be used. If tunneling could be done at all steel pipe would not provide the level of protection afforded by the HDPE pipe proposed by Lynn Haven. Placing the transmission line on pilings for an aerial route over North Bay is uneconomical and would create a potential hazard to navigation. Moreover, an aerial crossing would not solve any pollution problems should the transmission line leak or break and would also still involve a variance request since it would be necessary to dredge and fill in Class II waters for the placement of pilings or supports. Put simply, the evidence, showed that there was no realistic way to avoid Class II waters in North Bay given the location of the proposed wastewater treatment facility. A location which the City knew would require a hardship variance from the rule prohibition of dredging and filling in Class II, shellfishing waters. A hardship which the City created by site selection and which it hoped to overcome by strenuous permit conditions and futuristic speculative benefits to unsewered areas of the County. The existing treatment facility is operating in violation of both EPA and DER requirements, has been issued a notice of violation, is nonpermitted and is destined to be operating under a consent order. The system is hydraulically overloaded, handling approximately 1.2 million gallons per day while its rated capacity is 950,000 gallons per day. Refurbishing Lynn Haven's existing wastewater treatment facility would not be viable since the plant has outlived its useful life, is of a very poor design and probably could not be made to function within Departmental standards and water quality standards. The existing sprayfield does not function and results in overland flow of effluent which discharges to Class II waters. The high water table and presence of a semiconfining layer on the Lynn Haven peninsula virtually guarantee such discharges. Further, the plant only provides secondary treatment. Put simply, Lynn Haven needs another method of handling its sewage. The only remaining alternative to a Bay crossing is to tie into the existing Bay County system and any AWT wastewater treatment plant Bay County may build in the future. 8/ The existing Bay County system provides at most only secondary treatment. The Cherry Street facility, which is part of that system, functions essentially as a lift station rather than a treatment facility. The Military Point Lagoon portion of the system is nonpermitted and is operating under a consent order and has been the subject of enforcement action. The Department has an extensive agreement with Bay County requiring a significant and long term series of actions to deal with their wastewater treatment system. The modifications or improvements to the Bay County system to provide advanced treatment are not imminent and the final system conditions cannot now be determined as they will depend in large measure upon data and analysis remaining to be collected. Currently, the existing Bay County system processes a significant amount of industrial discharge and has a problem with phenols most likely due to industrial waste from two discreet industrial facilities in the County. 9/ However, all of Bay County's wastewater system problems are reasonably solvable and will be corrected in the near future, if they have not already been corrected. Additionally, the amount of sewage Lynn Haven would be sending into the current Bay County system probably would not significantly impact that system and its problems or the County's ability to solve those problems. The County is willing to accept Lynn Haven's sewage into its system and future AWT system. The connection into Bay County's system is a viable alternative currently in existence. Moreover, as indicated, Bay County has a long range plan to build an advanced wastewater treatment plant. As yet the plan remains "just a twinkle in the County's eye" and has not progressed to the design stage. However, this plan, of necessity, will eventually become reality in the next 5 to 10 years. The estimated cost to a Lynn Haven user for the Bay County conceptual system will be $25.00 per month in lieu of $15.00 for the proposed Lynn Haven system. These estimates are at best speculative. However, this cost estimate is not excessive given the fact that a Lynn Haven user lives in an environmentally sensitive area and a Bay County hook-up would eliminate the need to run a sewer pipe through food producing, Class II waters. 10/ Based on these facts, the evidence demonstrated that it was feasible for Lynn Haven to hook into Bay County's wastewater system without creating any more environmental impacts than that system is already experiencing and must solve and which, to a significant degree, have already been solved by Bay County. Given the existence of this alternative to crossing food producing waters and the fact that any future benefits are just as likely to be provided just as quickly by the County through AWT facilities, the applicant has failed to demonstrate the necessity for crossing North Bay and failed to demonstrate entitlement to a hardship variance for that crossing. Therefore, the applicant is not entitled to either a dredge and fill permit or variance for the proposed North Bay crossing.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is, recommended that the Florida Department of Environmental Regulation enter a final order issuing permit applications CS03178910, DC03178814, and 031785181, and denying the variance and permit number 031716641. RECOMMENDED this 27th day of November, 1991, in Tallahassee, Florida. DIANE CLEAVINGER Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 27th day of November, 1991.
The Issue The issue to be resolved in this proceeding concerns whether the Petitioner is entitled to the grant of a variance for the installation of an onsite sewage disposal system ("OSDS") for his property on the Santa Fe River in Gilchrist County, Florida, in accordance with Section 381.272, Florida Statutes, and Chapter 10D-6, Florida Administrative Code.
Findings Of Fact The Petitioner is the owner of certain real property located in Gilchrist County, Florida, more particularly described as Lot 4, Unit 4, Ira Bea's Oasis, a subdivision. The evidence is not clear concerning whether the plat of the subdivision was actually recorded, although the evidence and the Petitioner's testimony indicates that the lots in the subject subdivision were subdivided in 1965. The evidence does not clearly reflect whether the subdivision was ever platted, however. On April 2, 1990, the Petitioner filed an application for an OSDS permit regarding the subject property. The application was for a new OSDS on the above-described property; and the system was intended to serve a single- family residence, which the Petitioner desires to construct on the subject property for a vacation and retirement home. The proposed residence would contain three bedrooms and a heated or cooled area of approximately 1,100 square feet. In the permit application process, at the Respondent's behest, the Petitioner had a survey performed by Herbert G. Parrish, registered land surveyor. That survey, in evidence as the Respondent's Exhibit 1, reveals a benchmark elevation of 21.65 feet above mean sea level ("MSL"). The proposed installation site is at an elevation of 22.5 feet above MSL. A report by the Suwannee River Water Management District, which is admitted into evidence and was submitted to the Respondent by the Petitioner with the application for the OSDS permit, shows a ten-year flood elevation for the subject property, and River Mile 10 of the Santa Fe River, at 31 feet above MSL. Thus, the subject property is located beneath the ten-year flood elevation. The property is also located within the regulatory floodway of the Santa Fe River, as that relates to required engineering certification and calculations being furnished which will assure that if OSDS's are constructed employing mounding or sand filters, and like constructions, that such related fill deposited on the property within the regulatory floodway will not raise the level of the "base flood" for purposes of the rules cited hereinbelow. No evidence of such certification by an appropriately-registered engineer was offered in this proceeding concerning the installation of a mounded system and its effect on the base flood level. The surface grade level of the subject property at the installation site is 9.5 feet below the ten-year flood elevation. The grade elevation of the subject property is also .5 feet below the "two-year flood elevation", and the property has been flooded once in the past three years and has been flooded approximately four times in the past 15 years. It has thus not been established in this proceeding that the property is not subject to frequent flooding. On April 18, 1990, the Respondent denied the Petitioner's application for an OSDS permit by letter of that date. The Petitioner did not make a timely request for a formal administrative hearing to dispute that denial. The Petitioner maintained at hearing that this was, in essence, because the Respondent's personnel informed him that he should seek a variance instead, which is what he did. The testimony of Mr. Fross reveals, however, that, indeed, he was advised of his opportunity to seek a variance but was also advised of his right to seek a formal administrative hearing to contest the denial of the permit itself. Nevertheless, either through the Petitioner's misunderstanding of his rights or because he simply elected to choose the variance remedy instead, the fact remains that he did not timely file a petition for formal proceeding to contest the denial of the OSDS permit itself. Even had a timely petition for formal proceeding concerning the denial of the OSDS permit application been filed, the evidence of record does not establish the Petitioner's entitlement to such a permit. As found above, the property lies beneath the ten-year flood elevation and, indeed, lies below the two-year flood elevation, which subjects the property to a statistical 50% chance of being flooded each year. This and the other findings referenced above indicate that the property has not been established to be free from frequent flooding; and although appropriate "slight-limited" soils are present at the proposed installation site, those soils only extend 50 inches below the surface grade. That leaves an insufficient space beneath the bottom of the drainfield trenches where they would be located so as to have a sufficient volume and distance of appropriate treatment soil available beneath the drain field, if one should be installed. Below 50 inches at the subject site is a limerock strata which is impervious and constitutes a barrier to appropriate percolation and treatment of effluent waste water. Thus, for these reasons, especially the fact that the property clearly lies beneath the ten-year flood elevation and because adequate proof in support of a mounded system which might raise a septic tank and drainfield system above the ten-year flood elevation has not been adduced, entitlement to the OSDS permit itself has not been established. Concerning the variance application actually at issue in this proceeding, the Petitioner has proposed, in essence, two alternative systems. The Petitioner has designed, and submitted as an exhibit, a plan for a holding- tank-type- system. By this, the Petitioner proposes a 250-gallon holding tank, with a venting pipe extending approximately three feet above the level of the ten-year flood elevation, with an attendant concrete retaining wall and concrete base to which the tank would be securely attached. The Petitioner thus postulates that flood waters would not move or otherwise disturb the holding tank and that he would insure that the holding tank was pumped out at appropriate intervals and the waste there from properly deposited at a treatment facility located above the ten-year flood elevation. The precise method of such disposal and its location was not disclosed in the Petitioner's evidence, however. Moreover, the testimony of Dr. Hunter establishes that the deposition of waste water and human waste into the tank, either through pumping, or by gravity line, if the residence were located at an elevation above the inlet to the tank, might well result in a hydraulic condition which would cause the untreated sewage to overflow from the vent pipe of the tank. Moreover, such systems do not insure that public health, the health of the occupants of the site, and ground or surface waters will not be degraded since it is very costly to pump such a tank out which would have to be done on a frequent basis. This leaves the possibility that the user of such a holding-tank-facility could surreptitiously drain the tank into nearby receiving waters or otherwise improperly empty the tank. Even though the Petitioner may be entirely honorable in his intentions and efforts in this regard and not violate the law and the rules of the above-cited chapter in his manner of disposal of the holding-tank effluent, there is no practical, enforceable safeguard against such illegal activity, especially if one considers that the property may later be conveyed to a different landowner and user of the system. The Petitioner also proposes in his testimony and evidence the possibility of using a nondischarging, composting-toilet-type system to handle sewage involving human excreta. Such a system has been shown by the Petitioner's evidence to adequately treat human sewage so that public health and the ground and surface waters involved in and near the site could be adequately safeguarded. The problem with such a system, however, is that the "gray water", that is, waste water from bathtubs, showers, lavatories and kitchens, cannot be disposed of in the composting-toilet system. Such gray water, which also contains viruses, coliform bacteria and nutrients, must be disposed of, according to the rules at issue, in an appropriate sewage disposal system, be it in a septic tank and drain field or through pumping to an appropriate disposal and treatment facility located above the ten-year flood elevation. The Petitioner's proof does not establish how such gray water could be appropriately and safely disposed of in the environmental and public health context at issue herein. Thus, the proposed alternatives suggested by the Petitioner's proof do not constitute minor deviations from the minimum requirements for OSDS's specified in Chapter 10D-6, Florida Administrative Code. Ironically, the composting-toilet system, coupled with a proper disposal system for household gray water, could constitute a reasonable alternative to a conventional system. Thus, the Petitioner's proof, itself, shows that a reasonable alternative may exist, which militates against the granting of the variance, although he did not prove how it could feasibly be accomplished. In summary, therefore, the Petitioner's proof failed to establish that no reasonable alternative exists and that the proposed system would only be a minor deviation from the minimum requirements of the Respondent's rules concerning OSDS's and their installation and operation. The Petitioner established that a reasonable alternative to a conventional OSDS might exist for purposes of granting an OSDS permit itself, had that issue been formally placed before the Hearing Officer, but did not prove how it could feasibly be accomplished and operated. This proof shows, however, that such a reasonable alternative might be found operable which, thus, fails to justify the granting of a variance based upon hardship. If the Petitioner could come forward with proof to establish the feasibility of disposal and treatment of the household gray water involved in an appropriate treatment and disposal site and facility above the ten-year flood elevation, in conjunction with use of a composting- toilet system, a later permit application might be entertained in which could be justified the granting of an OSDS permit.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that a Final Order be entered by the Respondent denying the Petitioner's application for a variance from the statutory and regulatory requirements, cited above, for the issuance of permits. At such time as the Petitioner is able to show changed factual circumstances, as for instance, that a reasonable, feasible alternative system, which will adequately treat and dispose of all household waste water effluent in a manner comporting with the rules of Chapter 10D-6, Florida Administrative Code, a permit application should be entertained.
