The Issue The issues in this case are whether the Respondents, Enos Kerr and Custom Care Dry Cleaning, Inc., are guilty of the violations alleged in, should take the corrective actions described in, and should pay the penalties assessed in the Notice of Violation, Orders for Corrective Action, and Administrative Penalty Assessment, DEP OGC File No. 06-2382-37-HW (the NOV).
Findings Of Fact Enos Kerr is the President and manager and an owner of Custom Care Dry Cleaning, Inc., a dry-cleaning business located in Tallahassee, Florida. The Respondents have been in business for approximately twenty-five years. For approximately ten years, Custom Care has used Vista LPA-142 as a dry-cleaning solvent. Custom Care uses a spotting agent known as "Picrin" for removal of difficult stains. Vista LPA-142 is also known as paraffinic, napthenic solvent, and aliphatic solvent. It contains 100 percent paraffinic or napthenic solvent. It looks like water but is a white oily liquid that has the odor of hydrocarbon and is a kind of "mineral spirits." "Picrin" contains more than 98 percent chlorinated hydrocarbon. It is listed at 40 Code of Federal Regulations (CFR) § 372.65 and exceeds the de minimis concentration defined in 40 CFR § 372.38. On August 18, 2006, John Johnson, a DEP Environmental Specialist, inspected the premises of Custom Care. He found two partially full 55-gallon steel drums of Vista LPA-142 outside of secondary containment, which contained a 110-gallon storage tank and Custom Care's Midwest dry-cleaning machine (which has a base tank that stores used Vista LPA-142 which has passed through a Filter King purification system for reuse in the dry-cleaning machine). He testified that, not only did Mr. Kerr tell him the drums were full or partially full, they were heavy enough from being full or partially full that Mr. Johnson could not move them easily. On August 18, 2006, Mr. Johnson also observed, hanging on the outside of the wall of the secondary containment area, above the 55-gallon drums, some of the clear plastic tubing, a pump, and a PVC pipe extending from the end of the tubing, which were used to transfer Vista LPA-142 from the 55-gallon drums into the 110-gallon storage tanks. The floor beneath the transfer equipment and the 55-gallon drums was not sealed or otherwise treated to render it impervious. In another part of the premises on that date, also outside secondary containment, was a Forenta spotting board used for removal of difficult stains from fabric before placement in the dry-cleaning machine. Various chemicals, including a plastic bottle containing "Picrin," were in a box or tray attached to the spotting board. Beneath the spotting board was an open plastic waste basket used to collect and contain spotting agent suctioned from the item of clothing being cleaned and funneled to the basket. The floor under the spotting board was not sealed. Custom Care's Filter King purification system uses cloth filters. Periodically, Custom Care replaces the filters containing lint from the dry-cleaning process. The old filters are allowed to air-dry in the secondary containment area before disposal in the municipal solid waste dumpster outside the premises. At the end of Custom Care's dry-cleaning process, the dry-cleaned clothes are wrung out during a mechanical spinning cycle and then manually transferred while still damp or somewhat wet to a Huebsch dryer, which is outside secondary containment and on a floor that was not sealed on August 18, 2006. Air- drying is the last step in the process. DEP did not have the filters and lint analyzed to prove that they were contaminated with Picrin or any other hazardous substance. Instead, DEP assumed that there was some contamination, however small, and relied on the federal "mixture" rule that even the smallest amount of hazardous waste contamination turns previously unregulated solid waste into regulated hazardous waste. Count I - Secondary Containment Respondents' factual defenses to Count I, for not having the Vista LPA-142 in secondary containment on August 18, 2006, are: (1) secondary containment was not required because Vista LPA-142 is not a "dry-cleaning solvent"; and (2) if secondary containment was required, all of the Vista LPA-142 was in secondary containment because the 55-gallon drums and transfer equipment were empty. In support of their first defense to Count I, Respondents maintain that Vista LPA-142 is an aqueous solvent because an analysis of a sample from the base tank that collects used Vista LPA-142 after use and filtration for reuse in the dry- cleaning machine indicates the presence of 0.34 percent water. However, the presence of that small amount of water in the sample did not prove that Vista LPA-142 is an aqueous solvent. Custom Care also contends that Vista LPA-142 is not a "dry-cleaning solvent" because Custom Care buys it from Phenix Supply Company, which not only sells product to dry-cleaners but also sells to other businesses for other uses, making Phenix Supply something other than a "wholesale supply facility." This contention is rejected. See Conclusion 33, infra. Also in support of their first defense to Count I, Respondents pointed to information received from the producer of Vista LPA-142 that it was biodegradable to carbon dioxide and water. However, biodegradation would occur only in the presence of water and naturally-occurring microorganisms and aerobic conditions. Such biodegradation does not mean that Vista LPA-142 is an aqueous-based solvent and not a naphthenic, petroleum- based, dry-cleaning solvent. Respondents also believed Vista LPA-142 was not a petroleum-based dry-cleaning solvent because it has a flashpoint above 140 degrees Fahrenheit. But there was no evidence to prove that having a flashpoint above 140 degrees Fahrenheit means that the Vista LPA-142 is an aqueous-based solvent and not a naphthenic, petroleum-based, dry-cleaning solvent. In support of their second defense to Count I, Mr. Kerr denies telling Mr. Johnson the 55-gallon drums were full or partially full and maintains that the presence of a bung wrench on one of the drums was a fail-safe sign that both were empty (and, essentially, proved that Mr. Johnson was lying). Supposedly, according to Respondents, the Vista LPA-142 always is transferred immediately upon delivery from the 55-gallon drums into the 110-gallon tank and, sometimes, also into the base tank, and that the bung wrench is placed on one of the empty drums as a signal to the supplier that the drums are empty and ready to be removed when the supplier returns in two weeks to check on the drums to see if they are empty and ready to be picked up. This explanation is not logical. To the contrary, the use of the bung-wrench signal tends to prove the opposite--i.e., that the drums were not empty. If the Vista LPA-142 always is immediately transferred in its entirety, there would be need for a bung- wrench signal. Indeed, the Vista LPA-142 could be immediately transferred by the supplier (or by the Respondents while the supplier was still on the premises). In addition, Mr. Kerr conceded that there have been many other occasions when the 55- gallon drums were not completely transferred into the 110-gallon storage tank immediately upon delivery. There also have been occasions when three 55-gallon drums have been delivered by the supplier, all of which would not fit into the 110-gallon reserve tank and the base tank. In addition, during an enforcement meeting on September 13, 2006, to discuss a draft Hazardous Waste Inspection Report, while noting other issues with findings in the report, Mr. Kerr did not take issue with findings concerning the 55- gallon drums. Also in support of their second defense to Count I, Respondents maintain that the transfer equipment is emptied of all Vista LPA-142 before it is re-hung on the wall. This can indeed be accomplished by quickly extracting the PVC extension from the drum, reversing its orientation by 180 degrees so that it point toward the ceiling, and continuing to run the pump until the tubing is empty. In any event, while stains on the concrete floor under where the PVC pipe is hung on the wall may be from Vista LPA-142, which would suggest that the procedure is not always followed to perfection, the NOV did not cite Respondents having the transfer equipment outside of secondary containment. Count II - Unsealed Flooring Respondents' factual defense to Count II, for not having the flooring sealed between the secondary containment area where the dry-cleaning machine was and where the Huebsch dryer was, or where the 55-gallon drums were, is that secondary containment was not required because Vista LPA-142 is not a "dry- cleaning solvent." Factually, that defense already has been addressed in Findings 11-14, supra. Count III - Disposal of Solid Waste Respondents' factual defenses to Count III, for unpermitted and unauthorized disposal of solid waste (i.e., the filters and lint) on August 18, 2006, are: (1) that disposal of the filters and lint in the municipal solid waste dumpster is permitted and authorized because they are not hazardous waste; and (2) that, if they were hazardous waste, they were hazardous due to contamination with Picrin, not with tetrachloroethylene, also known as perchloroethylene or "perc," as alleged in the NOV. In support of their first defense to Count III, Respondents contend that all Picrin used in spot removal would be suctioned out of the item of clothing and collected in the container below the spotting board, or would be evaporated by the steam used in the spot removal process. Indeed, Picrin's boiling point is 165 degrees Fahrenheit, which is lower than the temperature of steam. Respondents contend, as proof of their first defense, that if any trace of Picrin remained on clothing after spot removal, it would be diluted in the Vista LPA-142 used in the dry-cleaning process and then returned to the base tank for reuse after the clothes are wrung out, but that a laboratory analysis of a sample of from the base tank did not indicate the presence of anything but water. However, actually the analysis was only performed to detect the presence of water; the sample was not analyzed for the presence of Picrin, or any of its breakdown products, or anything other than water. There may be traces of Picrin in the contents of the dry-cleaning machine's reservoir. Besides, even if there is no Picrin in the dry-cleaning machine's base tank, that evidence would not preclude the possibility that Picrin is filtered out by the Filter King purification process and is present in the filters and lint. Regardless, while the first defense to Count III was not proven, DEP presented no evidence on the question whether it is likely the filters and lint would be contaminated with Picrin. Rather, DEP's evidence assumed contamination without any further proof. As to Respondents' second defense to Count III, the NOV does in fact reference tetrachloroethylene, also known as perchloroethylene or "perc." However, it also calls the chemical "Picrin ® which contains 100% Tetrachloroethylene ('Perc')." The confusion arose because, during his inspection, Mr. Johnson obtained from Custom Care's files a Material Safety Data Sheet (MSDS) for Picrin. When he consulted with the manufacturer, he was told that the MSDS was out-of-date, and the manufacturer provided him with the current MSDS for Picrin. Then, the draft Hazardous Waste Inspection Report discussed during the enforcement meeting on September 13, 2006, referred to "today's Picrin [which] contains 100% Trichloroethylene ('Perc')." Mr. Kerr pointed out that "perc" was tetrachloroethylene, not trichloroethylene. From this, Mr. Johnson and Mr. Byer understood Mr. Kerr to be admitting to the use of "perc," which he was not. In an attempt to correct the report in accordance with Mr. Kerr's comment, DEP modified the report so that the final draft referred to: "today's Picrin [which] contains 100% Tetrachloroethylene ('Perc')." Even if the NOV is not defective in referring to "Perc" instead of clearly stating that Picrin was the alleged hazardous waste involved, DEP failed to prove that Picrin was mixed with the filters and lint. For that reason, DEP did not prove the allegations in Count III. Count IV - Investigative Costs The Department's proof of investigative expenses incurred consisted of the salary compensation paid to its investigators. Mr. Johnson’s salary is $17.53 per hour. He spent approximately 55 hours conducting inspections and investigating this case, which totals $964.15. Mr. Byer’s salary is $22.87 per hour. He spent approximately 96 hours investigating this case, which totals $2,195.52. Corrective Actions Upon re-inspection of the premises on November 8, 2006, Respondents were in compliance with all requirements. Deliveries of Vista LPA-142 were being transferred into the 110-gallon storage tank and base tank by the supplier upon delivery, and Respondents had sealed the flooring appropriately. It is not clear from the evidence what was being done with the filters and lint, but apparently they were being appropriately disposed of as hazardous waste at the time of the follow-up inspection. Other Mitigating Circumstances The evidence reflects a misunderstanding on the part of Respondents that, because Custom Care uses Vista LPA-142 and is considered a "mineral spirits" dry-cleaner, as opposed to a "perc" dry-cleaner that uses "perc" or some other form of chlorinated hydrocarbon that is a hazardous material in its dry- cleaning machine, it is not governed by dry-cleaning statutes and regulations.
Findings Of Fact On April 29, 1983, the Respondent Waste Aides Systems, Inc. (hereafter referred to as Waste Aides), filed with the Department of Environmental Regulation (Hereafter referred to as DER) an application to construct and operate a solid waste transfer station. The proposed transfer station would be located at the site of an existing solid waste landfill at Ridge Road and Landfill Road, New Port Richey, Florida. On May 24, 1983, DER, by letter to Waste Aides, requested additional information concerning the permit application and seeking further assurances with regard to control of wash down water and storm water runoff. On June 7, 1993, Waste Aides, by letter provided the additional information, and on June 14, 1983, DEP issued a letter of intent to issue the permit to Waste Aides. The proposed facility is to be located on a parcel of land previously used as a solid waste landfill, but the area where the facility is to be built is not a previously filled solid waste area. The proposed facility will utilize a building which is enclosed on the south, east, and west, and open to the north. The building will be approximately 120 feet wide, 48 feet deep, and 31 to 34 feet high. The general operation of the facility will be to transfer residential and commercial solid waste from garbage trucks to large tractor-trailer trucks for transport to a more isolated solid waste landfill. The facility will not accept hazardous waste or heavy industrial waste. The solid waste will be transported to the facility in garbage trucks. The solid waste will be dumped on a concrete floor inside the building and will then be pushed into a loading chute which sits directly above a waiting trailer. Once the trailer is filled, the solid waste is then transported to an offsite landfill where it is ultimately disposed of. Security at the facility will be accomplished through fencing and gates. The entire property is surrounded by a fence. A gate will be placed at Ridge Road, and a second gate will be installed at the entrance to the property itself. No unauthorized vehicles will be permitted to enter the property or unload solid waste at the facility. The facility will be equipped with two fire control hoses located on the east and west walls of the building. Potable water will be provided to the facility through a hookup to a 16-inch water main at Ridge Road. The facility will have impact sprinklers and spray bars inside the loading chute. Each vehicle on site will be equipped with a fire extinguisher, and two portable fir extinguishers will be located inside the building at appropriate locations. The impact sprinklers will also be utilized for dust control. Each vehicle on site will be equipped with a two-way radio which provides contact with the administrative office and maintenance area of the applicant. The phone in the cardboard recycling facility located on the same property of the proposed facility will be available for use by the operator of other employees of the transfer facility. The recycling facility is owned and operated by the applicant and is directly adjacent to the proposed transfer facility. The operator will be responsible for keeping records of materials handled by the facility. A recordation of volume will be measured and entered as collection trucks discharge their contents at the facility. A scale will be built into the loading area of the transfer trailers, and the weight of all refuse transferred will be recorded by load on a daily basis. These records will be open during normal business hours for inspection by DER representatives, health inspectors, and other authorized regulatory and enforcement agencies. The transfer station operator will be the foreman of the facility and will be present during all hours of operation. The tractor-trailer operator and the operators of the garbage trucks will be present at the facility during unloading and loading. Two or three other employees will also be present on the grounds at varying times for cleanup, grounds work, and other duties at the facility. The facility will be visited and checked approximately twice daily by William R. Peterson and his brother, the owners and operators of the proposed facility. The applicant has available personnel presently in the employment of the applicant, who is a certified driving instructor and who is skilled in the instruction of safe and efficient operating procedures. Additionally, Waste Aides will provide instructions in first-Aides procedures by a person presently employed who is a trained emergency medical technician. Debris will be controlled by certain mechanisms built into the design of the building and by certain operational procedures that will be observed by the transfer station operator. The tipping floor where solid waste is discharged will be enclosed on three sides. When the solid waste is discharged onto the tipping floor, it is immediately pushed into a chute which allows it to fall into the waiting transfer trailer. There is approximately an 8-inch tolerance between the chute and the top of the trailer, and the chute has been designed to angle in toward the trailer so that solid waste will be directed into the trailer to avoid spillage. Additionally, a rubber or fabric membrane will encircle the chute so that when the transfer trailer drives beneath it, the membrane will be inside the transfer trailer, thus directing all solid waste into the trailer itself. An additional benefit of this design is that it will avoid the possibility of drafts of air blowing refuse in the trailer over its sides. The trailer area itself is depressed and thus out of the direct wind stream. Drafts are further buffered by vegetation windbreaks consisting of trees and shrubs located on the west and south sides of the building and by the topographical nature of the surrounding lands on the other two sides. The entire area of the transfer station is fenced as a final barrier to debris escaping the transfer station site. The refuse will normally be on the tipping floor a very short period of time because of the fact that it will be pushed into the transfer trailer immediately upon discharged from the collection vehicle. The refuse, as it is discharged from the collection vehicle, does not lend itself to a debris problem in that it is in a compressed state and tends to remain in a semifragmented mass until it is moved into the trailer. The entire transfer station and surrounding grounds will be cleaned at the end of each day by the station operator. The station will be operated at all times to be in compliance with the applicable noise regulation and ordinances of Pasco County. For noise abatement, Waste Aides has designed the building with noise control in mind. The tipping floor will be constructed with steel rails imbedded in the concrete to eliminate the noise of the front-loading metal bucket scraping on the concrete surface. Six-foot walls buffet all sides of the tipping floor except the north side. The north side is open to an approximate 10-acre tract which was the previous landfill site and will be unoccupied. The tipping floor is enclosed by a building which will provide a significant amount of noise control in a and of itself. There are vegetation screening barriers and earthen berms on the north, west, and south boundaries of the site. The berms will be covered with mature vegetation and will act a both a noise and visual barrier for the site. All equipment used in the operation will meet all county, state, and federal operational decible standards. Odor control will be provided primarily by operational standards which will emphasize the rapid removal of refuse from the site. All refuse will be removed daily except for the possibility of partially filled trailers remaining overnight on site. Should a transfer trailer be required to remain on the site overnight, it will be driven inside the building not less than every 48 hours or in accordance with an approved DER schedule. The tipping floor will be completely cleaned at the end of each workday by being swept broom-clean and then washed down with hoses. When the floor is washed down, the water and debris will flow along the sloped floor to a grid system which will direct the flow into a sand trap and a grease trap and then into a septic tank. The traps will be checked each day after wash down and will be cleaned periodically. The building has been designed in such a manner that no square corner will exist for the possible buildup of refuse. These same operational procedures and design features will discourage any attraction to vermin or birds. Similar transfer station operations in Florida have not experienced the vermin and odor problems typically associated with landfill site operations. The prosed facility will have electric service available. Shelter as well as hand-washing and toilet facilities are available for employees for the facility at the adjacent recycling building. Maintenance on trucks and other equipment will be performed at the applicant's maintenance area located on Osteen Road, approximately 1 to 1 1/2 miles from the proposed facility. Although the proposed facility is surrounded by developed residential areas, the property which is directly contiguous to the property where the proposed facility will be located remains undeveloped. The objectors' travel- trailer park is the closest developed area, and the distance from the nearest trailer to the proposed facility is approximately 950 feet. The design and proposed operation of the transfer station meets or exceeds the criteria contained in Rule 17-7.09, Florida Adminstative Code. Numerous residents in the area object to the location of a garbage transfer station. Their objections are based upon their experience with odor, vermin, birds, and litter experienced in connection with the landfill operation. However, the uncontradicted evidence established that those problems will not exist to any substantial degree in connection with the operation of the proposed garbage transfer station.
Recommendation Based upon the foregoing findings of fact and conclusions of law, it is RECOMMENDED That the Department of Environmental Regulation issue a permit to Waste Aides Systems, Inc., for the construction and operation of the proposed transfer station, subject to the specific conditions contained in DER's Notice of Intent.

The Issue The issue is whether Respondent Department of Environmental Protection (DEP) may issue to Respondent Republic Services of Florida, L.P. (Republic), permits to construct and operate a Class III landfill, pursuant to Permit Numbers 266830-003-SC/01 and 266830-004-SO/01, as modified as set forth below.
Findings Of Fact Background On June 30, 2009, Republic filed with DEP an application for a permit to construct and operate a Class I landfill (Application). In response to DEP's request for additional information dated July 30, 2009 (RAI), Republic filed a response dated September 14, 2009 (RRAI), upon receipt of which, DEP deemed the Application to be complete. References to the Application typically include the Application, RRAI, and other materials, such as reports, plans, and drawings, that are part of the Application, as well as three subsequent modifications, which are detailed below. Republic revised several reports, plans, and drawings in the RRAI; references to these items, such as the Engineering Report and Operation Plan, are to the versions contained in the RRAI. On November 13, 2009, DEP filed its intent to issue construction permit #266830- 003-SC/01 (Construction Permit) and intent to issue operation permit #266830-004-SO/01 (Operation Permit; collectively, the Permit). Republic Services, Inc. and its affiliates constitute the second largest waste-management operator group in the United States. Their market capitalization is just over $11 billion. The capitalization of the affiliate formed to operate the subject landfill is doubtlessly less than $11 billion, as the record does not suggest that any significant part of the overall capitalization of Republic Services, Inc., and its affiliates would be at risk in the operation of the proposed landfill. Republic presently owns and operates a Class III landfill in the City of Bartow, Polk County, known as the Cedar Trail Landfill. The oldest part of this landfill is an unlined Class III landfill of 52.5 acres in the center of the property owned by Republic. Immediately west of this unlined landfill is a 30.7-acre lined Class III landfill, which comprises cells 1-4. The Cedar Trail Landfill is located at 2500 West State Road 60, about three miles west northwest of the intersection of State Road 60 and State Road 98, which marks the center of Bartow. The landfill is immediately west of E.F. Griffin Road. Petitioners Frost live on E.F. Griffin Road, about one mile north of the Cedar Trail Landfill. Petitioner Highland Lakes Estates Homeowner's Association serves a residential subdivision known as Highland Lakes Estates. Highland Lakes Estates occupies a notch at the southeast corner of Republic's property. Aerial photographs reveal the changing land use of the land on which Cedar Trail Landfill is situated. Fifty years ago, the land was vacant with indications of agricultural uses. At the site of the proposed landfill were mostly citrus groves on the west side and some rangeland or vacant land on the east side. Ten years later, a large area immediately northeast of the subject land reveals the effects of strip mining for phosphate. Three years later, in 1971, the mined area had greatly expanded to encompass all or nearly all of the subject site and much of the surrounding area, including the western half of what would become Highland Lakes Estates. By 1980, the pits had been refilled and active mining had ceased, and the streets had been constructed for what is now known as Highland Lakes Estates. By 1993, about three dozen homes had been built in this residential, large-lot subdivision. 9. The Cedar Trail Landfill was constructed in the early 1990s as an unlined construction and demolition debris landfill. Now designated an approved landfill for Class III waste, this facility accepts such waste as is defined by Florida Administrative Code Rule 62-701.200(14) (2010), which includes construction and demolition debris, yard trash, processed tires, asbestos, carpet, paper, glass, furniture (but not white goods), plastic, and other materials not expected to produce leachate that presents a risk to the public health or environment. A zoning/land use map reveals that the land for which the proposed landfill is proposed is designated "sewage/borrow pits/spray fields." Highland Lakes Estates occupies land that is designated single-family residential with a density of one dwelling unit on up to 2.49 acres. The Cedar Trail Landfill has been the subject of three recent environmental resource permits (ERPs). Appendix R to the Application is an individual ERP issued in April 2009, and Appendix R to the RRAI is a conceptual ERP issued in March 2005. The April 2009 ERP mentions that the entire stormwater project was conceptually approved by an ERP issued on September 10, 2008, but this ERP is not part of the record. In any event, these ERPs approve the construction of a comprehensive stormwater or surface water management system for the entire Republic property. In particular, the April 2009 ERP permits the construction of a borrow pit at the southeast corner of the Republic property and a modification of the perimeter ditch/wet retention system. The April 2009 ERP states that the permitted stormwater management system will provide total onsite retention for runoff from the 100-year, 24-hour storm. The April 2009 ERP requires 2.8 acres of compensation for 2.8 acres of encroachment in the 100-year floodplain. Specific Condition 14 prohibits excavation of the borrow pits to a clay confining layer or limestone bedrock layer. Specific Condition 20 prohibits the mixing of leachate with stormwater and provides that, if leachate enters stormwater, the stormwater becomes leachate. Presumably reflecting this permitting activity, Application Drawing 4, as revised in the RRAI, is the site plan, including the unlined Class III landfill, the four-cell lined Class III landfill immediately to the west of the unlined landfill, and the eight cells proposed to accept Class I waste. These eight cells are immediately south of the four cells of the lined Class III landfill. The two northernmost of these eight cells abut, on their east boundary, the unlined Class III landfill. The remaining six cells abut, on their east boundary, an 800-foot wide borrow pit, which lies between these cells and Highland Lakes Estates. Immediately north of Highland Lake Estates is a second borrow pit, and west of this borrow pit is the unlined Class III landfill. The other major feature on the site plan is a third borrow pit running, from west to east, along the north border of the lined Class III cells, the unlined Class III landfill, and the second borrow pit. Bearing no signs of ambitious reclamation activity, the backfilled mining cuts host large water storage areas and, as described in the application for the March 2005 ERP, wetlands of "very poor quality." The backfilled soils are best described as complex surficial soils, consisting mostly of fine sands with varying amounts of organics, silts, and clays. Geotechnical investigations of the Cedar Trail Landfill suggest that mining depths, although variable, probably averaged 40 feet. Petitioners and Intervenor are substantially affected by the Permit and the construction and operation of the proposed landfill, which will stand nearly 200 feet above grade and will be the focus of substantial activity six days per week during its years of operation. Like Petitioners, Intervenor owns land in the immediate vicinity of the Cedar Trail Landfill, which is in the jurisdiction of Intervenor, and Intervenor's various municipal operations are much affected by whether the proposed Class I landfill is permitted. Among other things, Intervenor has agreed to accept untreated leachate from the proposed landfill. Petitioners Frost built their home in 1980 or 1981. During the hours of operation of the existing landfill, Petitioners Frost constantly hear the beeping noise of heavy- duty equipment, presumably a safety device when the equipment is moved. Over a dozen lots in Highland Lakes Estates abut the property line of the Cedar Trail Landfill, and the closest residence is about 1000 feet from the nearest proposed Class I cell. At present, the existing landfill subjects the Highland Lakes Estates to constant noise during operating hours and a coating of dust inside their homes. Several residents of Highland Lakes Estates testified. Hard-working people, some of whom are now retired, these residents decided to purchase homes in Highland Lakes Estates because it was a sunny, healthy place to live. Over time, most of these residents, by varying degrees, have come to accept the fact of the Class III operations at Cedar Trail Landfill, but they object to the substantial intensification of land use that will result from a regional Class I landfill. One resident testified that she finds in her pool dirt that has escaped from the existing landfill, and she has become concerned about her grandchildren coming over to swim. Another resident testified that he only began closing his windows five or six years ago when the noise levels at the existing landfill increased; he eventually had to install a window air- conditioner. The same resident testified that the green herons and snowy egrets that he used to see around his house have not returned for five years, and his wife, who has health problems, including respiratory distress, would suffer from the expanded landfill operations. Application, RRAI, and Permit, Including Modifications The Permit incorporates the Application, including the RRAI, Engineering Report, Operation Plan, and drawings. Thus, all of the documents are part of the Permit. In the Application, Republic proposes to convert cells 5-8, which are not yet constructed, from a Class III to a Class I landfill and add four new cells adjacent to the unused cells. The unfilled portion of Cells 1-4 would continue to receive only Class III waste. Pursuant to Florida Administrative Code Rule 62-701.200(13) (2010), Class I waste is all solid waste, other than hazardous waste, that is not otherwise prohibited by rule. The Application states that the proposed landfill will serve communities within 100 miles. The service area of this regional landfill will thus extend in central Florida from Marion to Osceola counties, along the Gulf Coast from Pasco to Lee counties, and along the Atlantic Coast from Volusia to Martin counties. As stated in the Application, this service area is populated by 9.7 million persons, who would daily account for 3000 tons of waste at the Cedar Trail Landfill. Initially, according to the Engineering Report, the proposed landfill will receive 1600 tons per day of Class I waste, but, once the existing Class III cells are filled, the proposed landfill will receive 1600 tons per day of Class I waste plus the 1400 tons per day of the Class III waste that is currently going into the existing landfill. As revised by the RRAI, the life expectancy of the proposed landfill is seven years. The Application states that Republic will employ an attendant, a trained operator, and 3-5 spotters at the landfill. The Application reports that the landfill would operate Monday through Saturday from 7:00 a.m. to 6:00 p.m. and that the working face would be covered daily. The Application reports that Republic would install seven new detection wells and use 17 existing wells for monitoring groundwater and would use two existing staff gauges for monitoring surface water, evidently at a single location, as discussed in the next paragraph. 23. Application Appendix V is the Water Monitoring Plan. Appendix V states that surface water will be monitored every time that the stormwater pond for the leachate storage area discharges offsite, but not more frequently than weekly. Application Drawing 4, as revised in the RRAI, shows that the sole surface water monitoring location is close to the leachate storage tanks, which are described below. 23. Appendix V also requires leachate monitoring, "at least annually," for five field parameters--specific conductivity, pH, dissolved oxygen, colors, and sheens; eight laboratory parameters--including chloride, mercury, and total dissolved solids; and the parameters listed in 40 CFS Part 258, Appendix II, which includes a comprehensive list of volatile organic compounds; persistent organic pollutants, including 2,3,7,8-TCDD (a major dioxin) and Dibenzofuran; and metals, including lead and chromium. Fourteen days prior to all sampling events, Republic is required to notify DEP, so that it may obtain split samples for its own analysis. Republic is required to report the results of the groundwater monitoring quarterly and to analyze the groundwater data in a technical report filed with DEP every two years. Appendix V also requires monitoring for odors and combustible gases, mostly methane. Republic will monitor combustible gas quarterly at various ambient locations, such as the office buildings and to monitor combustible gas quarterly in the soil down to the seasonal high water table. The purpose of this monitoring is to determine combustible gas concentrations and, if they exceed 25%, take "all necessary steps to ensure protection of human health." Some confusion in the Application arises as to the issue of whether the Cedar Trails Landfill will be subject to, or voluntarily implement, the more elaborate provisions applicable to a landfill covered under Title V of the federal Clean Air Act, as amended in 1990. Regulated emissions for a new source might include particulate matter, sulphur dioxide, nitrogen oxides, volatile organic compounds (VOCs), and specified hazardous air pollutants. Appendix V states that the landfill will become a Title V landfill once permitted to receive Class I waste, and, at that time, it will be subject to a "more comprehensive system of landfill gas collection and monitoring." Appendix V assures that these items "will be addressed in separate documentation from this monitoring plan"--and, apparently, separate from the present record. By contrast, the Operation Plan concedes only that, based on the nature of Class I waste and the design capacity of the proposed landfill, Cedar Trail Landfill "may" become a Title V facility. The Operation Plan states: "If the regulatory thresholds at [Cedar Trail Landfill] are met [under Title V] requiring an active gas collection and control system (GCCS), [Cedar Trail Landfill] will submit as required the GCCS design plans for approval and install an active gas extraction system within the regulatory timeframes specified by Title 40, Code of Federal Regulations, Part 60, Subpart WWW." More specific provisions in the Operation Plan identify best management practices to prevent objectionable odors. Four practices are identified, including an "active gas collection and extraction system." On the DEP form application, which is a cover sheet to the more elaborate application materials, Republic checked boxes indicating that the landfill would use active gas controls with gas flaring and gas recovery, which is probably what is meant by an "active gas collection and extraction system." The Application provides that the landfill liner would be double composite; the leachate collections system would consist of collection pipes, geonets, and a sand layer; the leachate would be stored in tanks; some of the leachate would be recirculated as spray on the working face; and the remainder of the leachate would be stored onsite and periodically transferred to a wastewater treatment center for treatment. The Engineering Report states that the waste disposal footprint will not be located where geological formations or other subsurface features will not provide support for the waste. The Engineering Report identifies appendices addressing the slope-stability analysis and foundation analysis and relies on a March 12, 1997, report by Ardaman & Associates, Inc. (Ardaman Report), January 23, 2004, report by Golder Associates, Inc. (Golder Report), and June 26, 2009, report by Hanecki Consulting Engineers, Inc. (Hanecki Report). These items are discussed in greater detail below in connection with the sinkhole issue. The Engineering Report assures that the waste disposal footprint will not be within 500 feet of an existing or approved potable water well, nor will it be within 1000 feet of an existing or approved potable water well serving a community water supply. The Engineering Report adds that the minimum horizontal distance between waste deposits and the property line is 100 feet. The Engineering Report assures that the landfill footprint will not be in a dewatered pit, as the installation elevations are at least 2-3 feet higher than the seasonal high water table. The Engineering Report acknowledges that a small part of the eastern end of the four southernmost cells lies within the 100-year floodplain, as depicted by the Flood Insurance Rate Map effective December 29, 2000, and as shown in Application Appendix A, Drawing 1. Claiming that the relevant map was not revised in 2000, the Engineering Report asserts that the last update to the FIRM map was in 1975, and the depicted floodplain was filled during the mine reclamation process. The Engineering Report notes that the floodplain concerns were addressed in the April 2009 ERP. 34. The Engineering Report discloses two enforcement actions against Republic at the Cedar Trail Landfill. In a letter dated October 19, 2001, DEP warned Republic about noncompliant items at the site, and, in a notice of noncompliance dated January 30, 2006, DEP warned Republic not to use a new cell prior to construction certification of the cell's stormwater system. Both matters were reportedly resolved, and Republic has not been the subject of other enforcement actions for the Cedar Trails Landfill. At DEP's urging, the RRAI elaborates on enforcement actions against Republic or, evidently, Republic affiliates at a variety of Florida facilities, not just landfills. The additional information reveals that DEP imposed a fine of $61,300 for the October 2001 violations, which included disposing of unacceptable waste, storing an excessive number of tires and exceeding groundwater standards without notifying DEP, and a fine of $1000 for the January 2006 notice of noncompliance. The other enforcement actions against Republic or affiliates concerning landfills involved consent orders about the Nine Mile Road Landfill (Seaboard Waste): in February 2003, DEP imposed a fine of $13,000 in settlement of charges that employees were not removing all unacceptable waste from the site and, in November 2005, DEP imposed a $285 fine for a failure to submit required stormwater monitoring reports. There were many other enforcement actions, generally resulting in modest fines, but they involved hauling facilities, transfer stations, and materials recovery facilities, not landfills. The Engineering Report states that the proposed landfill is within six miles of, but greater than 10,000 feet from, the Bartow Municipal Airport. Airport safety is addressed in more detail below. The Engineering Report describes in detail the double composite liner system, which uses materials whose physical, chemical, and mechanical properties prevent failure due to contact with Class I waste and leachate, climactic conditions, installation stress, and other applied stresses and hydraulic pressures. The Engineering Report performs no contingency sinkhole analysis. The report does not suggest that the liner system could withstand the stresses and pressures resulting from any size sinkhole, so the necessary inference is that the liner will fail if any sinkhole forms directly beneath it. The Engineering Report states that waste placement will remain within the lined containment berm. The Engineering Report describes in detail the double composite liner system for use at the proposed landfill. The primary liner system and secondary liner system each comprises three layers with the top layer consisting of a composite drainage net, the middle layer consisting of a high-density polyethylene geomembrane with a minimum average thickness of 60 ml, and the bottom layer consisting of a geosynthetic clay liner with a maximum hydraulic conductivity of 5 x 10-9 cm/second. The Engineering Report describes in detail the leachate collection and removal system, which, sitting atop the primary liner, includes a 24-inch thick sand drainage layer with a minimum hydraulic conductivity of 1 x 10-3 cm/second, a composite drainage net, and a single perforated 8-inch diameter lateral pipe in each cell. The collection lateral pipes will gravity drain to the east to a header pipe that gravity drains to the primary leachate collection pump stations--one station for the four converted cells and one station for the four new cells. A smaller leachate collection and removal system will handle the leachate that penetrates to the leak detection layer by routing it to a secondary leachate collection pump station. Based on calculations derived from the HELP groundwater model, the leachate collection and removal system is designed to prevent leachate head from exceeding the thickness of the composite drainage net (about 1 cm) over the secondary geomembrane and from exceeding one foot over the primary geomembrane. According to the Engineering Report, flow meters will be installed at each of the pump stations to allow daily readings of the amount of leachate being pumped. At one foot of head over the primary liner, the Engineering Report expects just over three gallons per day collected at each secondary leachate collection pump station--significantly less than the leakage rate typical of a double liner system without a geosynthetic clay liner beneath the primary liner. However, the Engineering Report provides a standard action leakage rate of 100 gallons/acre/day, meaning that Republic is required to report to DEP liner leakage only when this leakage rate is attained. The pump stations will transmit the leachate to one of two above-ground, 150,000-gallon storage tanks. From these tanks, most of the leachate will be transported to an offsite location for treatment. However, up to 12,000 gallons per day of the untreated leachate will be recirculated to be sprayed on the working faces of the landfill. This is to control dust and possibly to assist with the degradation of the waste. The Engineering Report states that the Cedar Trail Landfill implements a facility-wide water quality monitoring plan. Upon completion of the pump stations for the eight cells that are the subject of the Application, Republic will expand its leachate sampling program to include annual sampling of the leachate collected in the primary and secondary leachate collection pump stations. The groundwater monitoring wells would be installed as closely as possible to the outer edge of the roadway that, with a stormwater ditch, will run the perimeter of the proposed Class I landfill. In the revised Engineering Report contained in the RRAI, Republic proposes a surface water discharge point in the stormwater pond located near the leachate storage tanks. The Engineering Report adds that Republic will continue to comply with the following prohibitions: No waste will be knowingly burned on site; Hazardous waste will not knowingly be accepted; PCB contaminated waste will not knowingly be accepted; Untreated biomedical waste will not knowingly be accepted. Please note that treated biomedical waste may be accepted at [Cedar Trail Landfill]'s Class I Landfill provided that the waste containers are marked "Treated Biomedical Waste.;" No waste disposal at the proposed Class I Landfill will occur within 3,000 feet of a Class I surface water body; [Cedar Trails Landfill] will not knowingly accept liquid waste within containers, excluding leachate and gas condensate derived from solid waste disposal operations. [Cedar Trails Landfill] will comply with the requirements of Rule 62- 701.300(10), FAC regarding the handling of liquid wastes; Neither oily waste nor commingled oily waste will knowingly be accepted; and Lead-acid batteries, used oil, white goods, and whole-waste tires will not knowingly be disposed of in the Class I waste disposal system. The Joint Stipulation to Permit Modification, identified above, adds four items to this list of operational prohibitions: i. Garbage will not be knowingly accepted; Household Waste, except waste from residential sources generated as Class III waste, will not be knowingly accepted; Animal carcasses will not be knowingly accepted; and Aluminum dross will not be knowingly accepted. Capitalized terms are generally defined in the Florida Administrative Code. Florida Administrative Code Rule 62-701.200(39) defines "Garbage" as " all kitchen and table food waste, and animal or vegetative waste that is attendant with or results from the storage, preparation, cooking, or handling of food materials." Application Appendix H is the Operation Plan, which also identifies the types of wastes to be permitted at the proposed landfill. Section 3(b) of the Operation Plan authorizes the proposed landfill to accept: Commercial waste Ash residue Incinerator by-pass waste Construction and demolition debris, including from a residence Treated biomedical waste Agricultural waste Industrial waste Yard trash, including from a residence Sewage sludge Industrial sludge Water/air treatment sludges Waste tires De minimis amounts of non-hazardous waste from incidental residential sources Section 5 of the Operation Plan provides, in relevant part: [Cedar Trail Landfill] will accept waste included in any of the waste categories identified under Section 3(b) of this Operation Plan[, but] will . . . NOT knowingly accept any hazardous waste, untreated biomedical waste, liquid waste (including paint), explosive waste, toxic waste, or radioactive waste for disposal at the [Cedar Trail Landfill.] Unacceptable types of refuse are listed below and will not be knowingly accepted for disposal. --Hazardous waste --Explosive waste --Radioactive waste --Drums that have not been opened and Emptied --Refrigerators, freezers, air Conditioners (white goods) --Any toxic or hazardous materials, i.e. batteries, solvents, oil, etc. --Automobiles or parts that contain fuel, lubricants, or coolants --Untreated Biomedical waste The original Application prohibited the acceptance of septic tank pumpage, but the application form accompanying the original Application indicated that the proposed landfill would accept industrial sludge and domestic sludge. After modification by the RRAI, the prohibition against accepting septic tank pumpage was deleted, and the Operating Plan added, among acceptable wastes, sewage sludge, industrial sludge, and water- and air-treatment sludge. Florida Administrative Code Rule 62-701.200(101) (2001) defines "sludge" to include solid waste pollution control residual from an industrial or domestic wastewater treatment plant, water supply treatment plant, air pollution control facility, septic tank, grease trap, portable toilet, or other source generating a waste with similar characteristics. Florida Administrative Code 62-701.200(64) (2001) defines "liquid waste" as any waste with free liquids, according to the "Paint Filler Liquids Test." As modified by the Joint Stipulation to Permit Modification, Section 5 of the Operation Plan was amended to add the following items to unacceptable types of refuse that will not be knowingly accepted for disposal: --Garbage --Household Waste, except waste from residential sources generated as Class III waste --Animal carcasses --Aluminum dross At the hearing, Republic and DEP agreed to an additional condition to the Operation Plan that unacceptable waste would include Garbage contained in commercial, industrial or agricultural waste. According to the Operation Plan, the initial waste screening occurs at the gate house where the attendant interviews the driver and inspects the incoming waste load. If the attendant sees more than a negligible amount of unauthorized wastes, he will reject the load and will contact the hauler to identify the source of the waste. Additionally, Republic will notify DEP if anyone tries to dispose of hazardous waste at the proposed landfill. As modified by the Joint Stipulation to Permit Modification, the Operation Plan was amended to provide a new paragraph between the paragraph addressing the initial waste screening at the gate house and, as discussed below, the second screening at the working face. The new paragraph provides: Any malodorous waste will be covered with mulch and/or additional soil or other approved cover materials to control odors promptly, within one (1) hour from the time of unloading, except in the event of exigent circumstances, such as extreme weather. Cedar Trail Landfill will promptly cover any sludge deposited on the landfill working face within one (1) hour from the time of the unloading, except in the event of exigent circumstances, such as extreme weather. At the hearing, Republic and DEP agreed to an additional condition to the Operation Plan, which would prohibit Republic from accepting malodorous waste or sludge that, due to exigent circumstances, it would not be able to cover within one hour from the time of unloading. If the load passes the initial waste screening, it will proceed to the working face of the landfill, according to the Operation Plan. At least one spotter will be stationed at the working face at all times that the landfill receives waste. Her job will be to detect unauthorized wastes. Republic is to assure that it has a sufficient number of spotters to find and remove unauthorized waste prior to compaction. The Operation Plan allows the spotter to work from ground level or the cab of a compactor. If the operator of a piece of heavy equipment is trained as a spotter, she may also serve as a spotter. During periods of higher waste traffic, the equipment operator will, according to the Operation Plan, "likely" need the assistance of another operator or spotter to screen the higher waste volumes. When finding unauthorized wastes in manageable volumes, the spotter or operator will remove these wastes by hand and place them into nearby containers for removal to an appropriate facility. The third waste screen occurs as the equipment operator spreads the waste, pursuant to the Operation Plan. The equipment operator is required to place any unacceptable observed wastes into containers, which will be located "within the lined area." These wastes will also be removed to an appropriate facility. In the RAI, DEP questioned the proximity of the containers to the working face, as the lined area consists of 72 acres, but, in the RRAI, Republic ignored the comment, restating only that the containers would not be located outside the lined area. The Operation Plan specifies a filling sequence. Republic will assure that the first layer of waste placed above the liner in each cell will be a minimum of four feet in compacted thickness and will be free of rigid objects that could damage the liner or leachate collection and removal system. Republic will maintain the working face to minimize the amount of exposed waste and initial cover necessary at the end of each day. The filling sequence will proceed until the permitted final grade elevations have been reached, less three feet for the final cover. The Operation Plan states that the initial cover at the Class I landfill will consist of a six-inch layer of soil that is transferred from onsite borrow pits or offsite sources. This soil will be compacted and placed on top of the waste by the end of each work day. At Republic's option, subject to DEP's approval, it may use a spray-on or tarpaulin cover, instead of a soil cover. The Operation Plan requires Republic to apply at least one foot of intermediate cover within seven days of cell completion, if additional waste will not be deposited within 180 days of cell completion. Republic may remove all or part of this intermediate cover before placing additional waste or the final cover. Through the placement of initial, daily, and intermediate cover, Republic will minimize the occurrence of moisture infiltration, fires, odors, blowing litter, and animals and other disease vectors. 59. The Operation Plan requires Republic to control litter primarily by daily waste compaction and cover. However, at least daily, if needed, employees will collect litter along the entrance and access roads and around the working face. Complaints about litter must be logged. In addition to the inspections detailed above, the Operation Plan establishes a random load-checking program to detect unauthorized wastes. Each week, Republic employees will examine at least three random loads of solid waste by requiring drivers to discharge their loads at a designated location within the landfill where the employees may undertake a detailed inspection. All random inspections will be logged. Notwithstanding the daily limit of 12,000 gallons per day, the Operation Plan prohibits Republic from spraying leachate during rain events. To apply the recirculated leachate, the lead operator will drive the leachate tanker truck on the working face, so that it can spray leachate over waste as it is being compacted, but after it has been screened by spotters. The spraying will be done to avoid causing leachate to pond atop the waste and will not be done within 50 feet of an outside slope. No restrictions apply to wind conditions. The Operation Plan states that, if the annual sampling of leachate water quality at the two pump stations reveals a contaminant in excess of the permissible limits listed in 40 CFR Part 261.24, Republic will start monthly sampling and notify DEP in writing. Also, the Cedar Trail Landfill will maintain a recording rain gauge. The Operation Plan requires Republic employees to conduct daily surveys for objectionable odors and take immediate corrective action, if odors are found at the property line. As modified by the Joint Stipulation to Permit Modification, this portion of the Operation Plan was amended to add two odor- remediation actions and another form of odor inspection. The two additional actions to prevent odors are to 1) provide additional cover using mulch, additional soil, or other approved cover material and 2) use odor masking or neutralizing agents. The new inspection provision states: Internal inspection will be performed on a weekly basis by a properly trained odor ranger or equivalently trained person. Such individual will tour the facility, property boundary, and the subdivision of Highland Lakes Estates . . . to identify any odors leaving the Landfill's property boundaries. The results of each weekly inspection will be document, and any odors identified will be mitigated. Another new provision from the Joint Stipulation for Permit Modification applies to the handling of sludge. As amended, the Operation Plan states: When accepting sludge from a new source or distributor, [Republic] will obtain information regarding the characteristics and constituents of the sludge, including a description of the industrial process or circumstances that resulted in the generation of the sludge. Upon delivery of the sludge, [Republic] will mix lime, sodium hydroxide, or any other suitable agents to eliminate objectionable odors as required during disposal of the sludge before the material is covered. Furthermore, [Republic] will obtain advance notice from contributors prior to delivery of any sludge and shall promptly cover any sludge unloaded on the landfill working face within one (1) hour from the time of unloading, except in the event of exigent circumstances, such as severe weather. [Republic] shall use its best efforts to avoid accepting or disposing of sludge on Saturdays, Sundays, or public holidays. Additionally, with respect to sludge received from wastewater treatment facilities only, such sludge shall not exceed the lesser of (1) twenty percent (20%) of the total volume of waste disposed in the landfill on an average monthly basis, determined annually on the prior calendar year, or (2) two-hundred (200) tons per day, averaged over the prior 12-month calendar year. Republic is required to monitor combustible gases quarterly and transmit the results to DEP, according to the Operation Plan. If Republic detects methane above the limits specified in Florida Administrative Code Rule 62-701.530 (2010), Republic must submit a gas remediation plan to DEP within seven days. The Operating Plan indicates that the separation of the waste from the groundwater prevents the saturation of the waste and, thus, the generation of odor. Sloping and compacting will promote stormwater runoff, again to discourage the generation of odor. The Construction Permit authorizes construction of the proposed landfill in accordance with the "rules[,] . . . reports, plans and other information" submitted by Republic "(unless otherwise specified)." This parenthetical reference provides that the provisions of the Construction Permit control over any contrary provisions in the other documents that are part of the Permit due to incorporation by reference. In addition to the original Application, RRAI, and drawings, the Construction Permit also incorporates Florida Administrative Code Chapter 62-701 (2001). The Construction Permit states that Republic may not violate the prohibitions set forth in Florida Administrative Code Rule 62-701.300, which is discussed in the Conclusions of Law. Construction Permit Specific Condition A.9.a requires notification to DEP of the discovery of limestone during excavation or discovery. Specific Condition A.9.b requires notification to DEP of any surface depressions or other indications of sinkhole activity onsite or within 500 feet of the site. Specific Condition A.9.c prohibits open burning. Construction Permit Specific Condition C.1.b prohibits the discharge of leachate, during construction or operation, to soils, surface water, or groundwater outside the liner and leachate management system. Specific Condition C.4 prohibits the acceptance of hazardous waste and does not condition this prohibition on Republic's knowledge that the waste is a hazardous waste. Specific Condition C.5 requires Republic to "control . . . odors and fugitive particulates (dust)" and "minimize the creation of nuisance conditions on adjoining property." "Nuisance conditions" include "complaints confirmed by [DEP] personnel upon site inspection." Specific Condition C.5 orders Republic to "take immediate corrective action to abate the nuisance" and to "control disease vectors so as to protect the public health and welfare." Construction Permit Specific Condition C.6.b requires immediate notice to DEP of any sinkholes or other subsurface instability. Specific Condition C.8 requires Republic to manage leachate in accordance with the Operating Permit and Florida Administrative Code Rule 62-700.500(8). The Operating Permit incorporates the same materials that are incorporated into the Construction Permit, again "(unless otherwise specified)." Like the Construction Permit, the Operating Permit incorporates Florida Administrative Code Chapter 62-701 (2001) and requires immediate notice to DEP in the event of a sinkhole or subsurface instability. The Operating Permit specifies that the action leakage rate is 100 gallons per acre per day and the leachate recirculation rate is 12,000 gallons per day. As modified by the Joint Stipulation to Permit Modification, Operating Permit Specific Condition A.1.b states: This Facility is not authorized to accept Garbage; untreated Biomedical Waste; animal carcasses; liquids and non-liquid PCB containing materials or wastes with a PCB concentration greater than or equal to 50 parts per million; Liquid Waste; and aluminum dross. Additionally, this facility is not authorized to accept Household Waste, except waste from residential sources generated as Class III waste. Class III waste means yard trash, construction and demolition debris, processed tires, asbestos, carpet, cardboard, paper, glass, plastic, furniture other than appliances, or other materials approved by [DEP] that are not expected to produce leachate which are a threat to public health or the environment as defined in Rule 62-701.200(14), F.A.C. Based on this authorization to allow certain wastes as described above from residential sources, and since the landfill design, including liner and leachate collection systems, meets the requirements of Chapter 62-701, F.A.C., for Class I landfills, the facility will be entitled to [the] household hazardous waste exemption pursuant to 40 C.F.R. 261.4(b)(1). Specific Condition A.9.c prohibits open burning. Operating Permit Specific Condition C.1.b prohibits the discharge of leachate to soils, surface water, or groundwater outside the liner. Specific Condition C.1.c prohibits the discharge of "residual contaminants," such as gasoline, oil, paint, antifreeze, and polychlorinated biphenyls (PCBs), onto the ground or into surface water or groundwater. Operating Permit Specific Condition C.1.k(1) provides that authorized waste types are those listed in Section 3(b) of the Operations Plan, and unacceptable wastes shall be removed from the site as described in Sections 3(a) and 7. As modified by the Joint Stipulation to Permit Modification, Operating Permit Specific Condition C.1.k(1) provides: "Waste types authorized for management at this site are those listed in Section 3(b) of the Operations [sic] Plan. Unacceptable wastes are those listed in Section 5 [of the Operation Plan] " Operating Permit Specific Condition C.1.k(2) requires the use of a sufficient number of spotters to remove unacceptable wastes, but allows Republic to direct its equipment operators to serve as spotters from the equipment. This condition allows DEP to require that spotters work from the ground, if DEP determines that spotting from equipment is not effective. Specific Condition C.1.k(3) requires Republic to remove unacceptable wastes immediately and not to unload additional wastes in the immediate vicinity until placing unacceptable wastes in the designated waste containers" "near the working face" and within the lined landfill area. Operating Permit Specific Condition C.1.l(2) requires Republic to inspect on each operating day the property boundary for objectionable odors and, if any are detected, abate them in accordance with Specific Condition C.5. Specific Condition C.5.a requires Republic to control odors, disease vectors (insects and rodents), and fugitive particles (dust and smoke) to protect the public health and welfare. Control is defined as "minimiz[ing]" the creation of nuisance conditions on adjoining property. Odors confirmed by DEP personnel are a nuisance condition, and Republic must take immediate corrective action to "abate" the nuisance. Specific Condition C.5.b provides that, if odor control measures do not "sufficiently abate" objectionable odors within 30 days, Republic will submit an odor remediation plan to DEP for approval. Operating Permit Specific Condition C.8.e requires monthly reports to DEP of leachate quantities. Specific Condition C.8.h(1) prohibits recirculation of leachate at rates that result in seepage that may discharge outside the lined area. Leachate may not be sprayed when the application area is saturated or during a rainfall event. There is no prohibition against spraying during windy conditions. Operating Permit Specific Condition E details the extensive water quality monitoring requirements. However, Specific Condition E.9.b requires only annual testing of the five field parameters, eight laboratory parameters, and the comprehensive list of Appendix II parameters set forth in 40 CFR Part 258, all of which are identified below. Specific Condition E.9.c provides that, if a contaminant listed in 40 CFR 261.24 exceeds the level listed therein, Republic will notify DEP and take monthly leachate samples until no exceedances are detected for three consecutive months. Operating Permit Specific Condition F.1.a states: "This solid waste permit will meet the statutory requirement to obtain an air construction permit before . . . constructing a source of air pollution, except for those landfills that are subject to the prevention of significant deterioration (PSD) requirements of Chapter 62-212, F.A.C." Such facilities are required to obtain an air construction permit from the Bureau of Air Regulations prior to construction. Specific Condition F.1.b requires Republic to comply with Title V of 40 CFR 60, Subparts WWW and CC. This section notes that Title V permit applications must be submitted to the District Air Program Administrator or County Air Program Administrator responsible for the landfill. Aviation Safety Landfills attract birds in search of food. Flying birds may interfere with aviation safety. Thus, landfills are typically not located in close proximity to airfields to minimize the risk that flying birds will interfere with airborne aircraft approaching or departing from an airport. The nearest airport to the Cedar Trail Landfill is the Bartow Municipal Airport, which is operated by the Bartow Aviation Development Authority. This airport is over five miles from the footprint of the active landfill and 4.6 miles from the boundary of the proposed site. Republic provided notice of the Application to all airports within six miles of the proposed landfill, the Federal Aviation Administration, and the Florida Department of Transportation. None of these entities objected to the proposed landfill. When Republic gave the Bartow Aviation Development Authority notice of an earlier application, which sought a permit for a landfill that would accept garbage, the authority objected to the proposal due to concerns posed by birds to aviation safety. When asked about the Application, the authority's executive director testified that she still has concerns about the proposed landfill, but she did not specify the nature of her concerns or her analysis. As explained in the Conclusions of Law, these are the only facts required for a determination of whether Republic has provided reasonable assurance of aviation safety. The record provides no basis for finding that Republic has failed to provide reasonable assurance of aviation safety. Neither the FAA nor the Bartow Aviation Development Authority has objected to the proposed landfill. The executive director's unspecified concerns do not override the absence of a formal objection from these agencies. Petitioners assign too much weight to the earlier objection submitted by the authority. The composition of the authority may have changed or some authority members may have decided they were wrong in their earlier analysis. This earlier objection does not outweigh the absence of objection to the present proposal from any of the aviation agencies and the absence of any evidence of the expected nature or extent of bird usage of the proposed landfill and the extent to which these birds would interfere with existing and expected flight paths of aircraft using the Bartow Municipal Airport. Public Health Petitioners' expert witness on public-health issues, Dr. David Carpenter, is a medical doctor with a long, prestigious history of public service, including with the Department of Defense, the National Institutes of Mental Health, the United States Public Health Service, and the New York Department of Health, where he served as director from 1980-85. At that time, Dr. Carpenter started the School of Public Health at the University of Albany. Republic's expert witness on public-health issues, Dr. Christopher Teaf, is an expert in the evaluation of environmental contamination, waste management, and toxicology, but not a medical doctor. Dr. Teaf is a professor at Florida State University and owns a small consulting firm. The major part of Dr. Carpenter's career has been devoted to research. For the past ten years, he has focused more on human health, especially human disease from exposure to environmental contaminants. Dr. Carpenter has considerable experience with the adverse effects of landfills on human health, but his experience has been mostly with older landfills, where containment measures were few and offsite releases were many. Clearly, Dr. Carpenter's experience does not extend to the role of landfill design, construction, and operation in the transmission of human disease. Thus, Dr. Carpenter is qualified to opine on the effects of pollutants that may escape landfills, but not on the relationship of landfill design, construction, and operation on the probability that a landfill will transmit pollutants. For the most part, Dr. Carpenter did not attempt to address matters outside of his expertise. However, Dr. Carpenter testified that the risk of disease or injury increased in relationship to the proximity of the person to the landfill. This testimony can only be credited if one assumes that the landfills are identical in terms of design, construction, and operation and in terms of the environmental conditions of the landfill site. In other words, in real-world applications, it is impossible to credit this element of Dr. Carpenter's testimony, especially to the extent of his implicit suggestion that public health is unreasonably endangered by the construction of a landfill, in compliance with all rules, that satisfies all of the separation criteria and design criteria set forth in the rules, as discussed below. By contrast, Dr. Teaf focused on the details of the proposed landfill. Applying his knowledge of toxicology, Dr. Teaf determined that the proposed landfill adequately protects public health. In making this determination, Dr. Teaf analyzed the effects of various design and operational characteristics of the proposed landfill, including the double liner system, the leachate collection and management system, the selection of appropriate waste types, the procedures for the evaluation and covering of sludges, the prohibition against municipal garbage, the restrictions on household items, the monitoring of groundwater and surface water, the stormwater management system, and the plans to control dust and odors. Dr. Carpenter's testimony and the literature that he sponsored suggested important links between older landfills and a wide range of human disease. But the recurring problem with Dr. Carpenter's testimony and the research articles that he sponsored was the inability to link this information to the proposed landfill. All of the landfills studied in his research articles were older, and most of them appeared to have been designed, constructed, and operated under far more relaxed regulatory regimes than exist today. Nothing in Dr. Carpenter's testimony or sponsored literature attempted to delineate the design or operational characteristics of these landfills, such as whether they were double- or even single-lined, served by leachate circulation and recovery systems, limited as to materials that they could accept, or required to install stormwater management and water monitoring systems. 93. Analysis of the risk to public health posed by the proposed landfill requires consideration of the various means of transmission of the pollutants received by the landfill: water, land, and air. Of these, water requires little analysis, on this record. Even Dr. Carpenter conceded that the proposed landfill does not appear to pose a threat to groundwater. The double liner, leachate collection and recovery system, and groundwater monitoring plan support the finding that groundwater transmission of pollutants from the proposed landfill is unlikely. Transmission by surface water is also unlikely. Compared to groundwater monitoring, surface water monitoring is limited. For instance, there is only a single monitoring site. Also, as noted above, the stormwater pond for the leachate storage area is expected to discharge stormwater offsite during excessive storm events, at which time surface water samples will be taken. However, a comprehensive surface water management system is in place at the landfill and will prevent offsite discharges in all but a few excessive rain events. Transmission by land is also unlikely. The Application contains engineering analysis of the proposed stability of the side slopes and a determination that they will be stable. The discussion of sinkholes, below, does not affect this finding. Treating dust as transmission by air, the only other means by which pollutants may transmit by land is by animals, such as insects, rodents, and birds. An important factor limiting the activity of animals in spreading pollutants offsite is the fact that the proposed landfill will not receive garbage. Although putrescible waste may be received within other categories of waste, the prohibition against receiving garbage will greatly reduce the amount of potential food sources for animals and thus the utilization rate of the proposed landfill by these animals. A further reduction in animal utilization will be achieved through the daily and intermediate cover requirements. Thus, transmission of pollutants by animals is also unlikely. Transmission by air takes several forms. Pollutants may be transmitted as or on dust, with water in the form of aerosol, or as gas. In terms of how transmission by air is addressed by the Permit, this means of transmission potentially represents a greater threat than transmission by water or land for four reasons. First, the explicit focus of the Permit, as to gas, is to avoid explosive concentrations of methane and objectionable odors, but not the transmission of other pollutants by air. Second, the effect of the Permit is to prohibit the release of pollutants into the groundwater or offsite surface water and to prohibit the release of pollutant-bearing land offsite, but no such flat prohibition applies to the offsite release of pollutants by air. Third, the leachate recirculation system provides a good opportunity for the release of certain pollutants into the air by aerosol or evaporation, but similar releases to offsite land, surface water, or groundwater are prohibited. Fourth, scientific understanding of the effects of exposure, especially by inhalation, to pollutants, especially in the form of organic compounds, is continuing to develop: with the use of chemicals increasing three fold in the 50 years preceding 1995 and approximately 80,000 chemicals in use in 2002, only a few hundreds of these chemicals have been subjected to long- or short-term study, resulting in the discovery that about 10% of the chemicals in use in 2002 were carcinogens. Transmission by dust appears to be limited by the frequent covering and spraying of the working faces. Although nearby residents complain of dust in their homes, the practices of the less-regulated Class III landfill cannot be extrapolated to the proposed Class I landfill. Thus, the prospect of dust transmission of chemicals contained in the fill received by the proposed landfill appears also to be slight. The use of untreated leachate as the spray medium to control the dust itself raises two risks, however. First, spraying leachate will release chemicals in aerosol. The potential range of aerosol is great, especially as the landfill ascends toward its design height of 190 feet. However, the risk of transmission by aerosol is reduced to insubstantial levels by adding a Permit condition that prohibits spraying during windy conditions. Second, depositing leachate on the landfill face will release chemicals through evaporation. The point of spraying the landfill face is to control dust between the addition of the waste materials to the pile and the application of the cover. Between these two events, dry conditions will sometimes intervene and may cause the evaporation of certain, but not all, pollutants. The leachate acquires pollutants as it percolates down the waste column and into the leachate collection system. As Dr. Teaf noted, the leachate becomes more concentrated as it recirculates, but, otherwise, this record is largely silent as to the likely composition of the recirculated leachate. However, for landfills accepting sludge, higher levels of mercury may be present in the leachate. As reported by the Florida Center for Solid and Hazardous Waste Management at the University of Florida, in a report issued March 2007, and titled, "Design and Operational Issues Related to Co-Disposal of Sludges and Biosolids and Class I Landfills--Phase III," one study found that the concentration of mercury in the leachate of landfills that receive sludge is almost three times greater than the concentration of mercury in the leachate of landfills that do not accept sludge. The same study reported that total dissolved solids and chlorides were present at greater concentrations at the landfills that did not accept sludge and that other parameters--unidentified in the cited article--were not significantly different between the two types of landfills. Republic proposes to recirculate substantial volumes of leachate--sufficient, for instance, to raise the moisture content of the fill from 25 percent to 28.9 percent. The Permit allows the proposed landfill to operate six days per week, for a total of 312 days annually. The Operation Plan prohibits the application of leachate during rain, but the number of days annually during which rain extends for the entire day is few, probably no more than a dozen. These numbers suggest that Republic may apply as much as 3.6 million gallons annually of untreated leachate to the landfill face. The 12,000 gallon-per-day limit and restrictions on head in the leachate collection and removal system effectively limit the quantities of leachate that may be recirculated, but the sole provision addressing leachate water quality is the annual monitoring event described above. Given the time required to analyze the many parameters included in the EPA regulation, for most of the year between tests, Republic will be applying over three million gallons of leachate whose pollutant concentrations will be completely unknown. Some assurances emerge, though, when considering air transmission of pollutants by class. In general, on this record, as to transmission by gas, there appears to be an inverse relationship between a compound's volatility, which is a measure of its ability to enter the air, and a compound's persistence. VOCs are one of the most dangerous classes of pollutants to public health and include such carcinogens as benzene, tolulene, xylene and, the most dangerous of all VOCs, vinyl chloride, which is released upon the degradation of such common substances as plastics, carpets, and upholstery. Biogas, which is generated by the anerobic decomposition of organic compounds in a landfill, contains mostly methane and carbon dioxide, but also significant levels of VOCs. When inhaled, the primary results of exposure to VOC are respiratory irritation and allergenic effects. Volatility is measured by vapor pressure, which is a measure of a chemical's ability to get into the air. As their name suggests, VOCs enter the air easily. They are also capable of traveling great distances due to their light molecule. However, VOCs are easily destroyed by sunlight and diluted by wind. Other organic compounds common to landfills are only semi-VOCs, such as PCBs. Although less volatile, these chemicals, too, are hazardous to public health--in the case of PCBs, in any amount. Due to this fact and their persistence in the environment, the United States has prohibited the manufacture of PCBs for over 30 years. However, not only are PCBs considerably less likely to enter the air than VOCs, they also travel shorter distances than VOCs due to a heavier molecule. Dr. Carpenter opined that there is little evidence that PCBs are an issue in the proposed landfill. Another class of organic compound, 1000 times less volatile than even PCBs, is phthalates, which are used in the production of plastics. Phthalates pose significant threats to public health, especially reproductive health. However, the exceptionally low volatility of this compound renders transmission by evaporation highly unlikely. Much of the regulatory framework imposed on landfill design, construction, and operation arises out of concerns for the control of human pathogens, which are infection-causing organisms, such as bacteria, viruses, protozoa, and parasitic worms. One of the great advances in human longevity in the United States occurred in the early 1900s--not with the development of antibiotics or improved medical care--but with the implementation of basic sanitation control and the removal of pathogens from the drinking water. For the proposed landfill, sludge will be the primary source of pathogens. Sludge is nutrient-rich organic matter, which will be received at the proposed landfill without any treatment except possibly dewatering. Even with the acceptance of sludge, the proposed landfill presents little risk for the transmission of pathogens. Pathogens communicate disease only when a person is exposed to an effective dose and are better transmitted by direct contact or animal than air. Bacterial pathogens are themselves killed by wind, as well as sunlight, temperature, and humidity differentials, so the preferred means of air transmission would be aerosol versus gas. The record permits no findings as to the persistence of pathogenic viruses, protozoa, and parasitic worms. However, as noted above in connection with the land transmission of pathogens, the immediate application of lime and cover to the sludge will tend to prevent the release of effective doses of pathogens by air, as well. The last major class of pollutant that could be transmitted by air is heavy metals, such as mercury or lead. Although these metals produce a wide range of neurological diseases and generally interfere with cognition and behavior, Dr. Carpenter admitted that heavy metals were not as much of a concern as VOCs, presumably due to their resistance to vaporization. Even though transmission by air is not as tightly controlled as transmission by water or land, for the four reasons noted above, there is little risk of transmission by air--i.e., dust, aerosol, or gas--when the specific properties of likely pollutants are considered. In all but five respects, then, Republic has provided reasonable assurance that public health will not be endangered by pollutants released from the landfill by water, land, or air. First, to provide reasonable assurance concerning public health, the Permit needs a condition that prohibits spraying leachate during windy conditions, which DEP may define as it reasonably sees fit. As noted in the Conclusions of Law, this is a requirement in the rules and, due to its importance, should be restated explicitly in the Permit, which restates numerous other rule requirements. Second, to provide reasonable assurance concerning public health, the Permit needs more frequent monitoring of leachate water quality, at least at the frequency, as noted in the Conclusions of Law, set forth in the rules. Large volumes of untreated leachate will be recirculated through the landfill. Even if aerosol transmission is controlled, transmission by evaporation of some pollutants, although not the heavy metals, is possible. Also, pollutants are concentrated in recirculated leachate and thus the consequences of transmission into groundwater or surface water, however unlikely, become greater. At the same time, the action leakage rate is generous--to Republic, not the groundwater. At 100 gallons per acre per day, Republic is not required to report to DEP possible liner leakage until about 7300 gallons per day are lost to the surficial aquifer. Suitable for the detection of catastrophic failures associated with most sinkholes, this action leakage rate is too high to trigger action for small liner leaks. If Republic is to be allowed this much leakage into the groundwater, it must identify the leachate's constituents and their concentrations at least semi-annually. Third, to provide reasonable assurance concerning public health, the Application must extend the right of split testing to all of the parties in these cases, if DEP fails to exercise its right to take a split sample. The spraying of untreated leachate and generous limit applied to liner leakage before reporting and remedial action are required underscore the importance to public health of independent leachate testing. There is no reason to allow budgetary constraints or administrative oversight to preclude Petitioners and Intervenor, who are uniquely situated to suffer from the escape of excessive pollutants in the leachate, from providing, at their expense, this independent leachate testing. Fourth, to provide reasonable assurance concerning public health, the Permit needs to restate accurately the language of the rules concerning the extent of knowledge required of Republic, if it is to be liable for the acceptance of certain prohibited wastes. Fifth, to provide reasonable assurance concerning public health, the Permit needs to be modified to ensure that at least one spotter, whose sole responsibility is spotting, will be assigned to each working face while the landfill is receiving waste. Sinkholes The sinkhole issue arises in the geotechnical analysis of the sufficiency of the foundation to support the considerable loads of a landfill and also in the stability of the side slopes of the landfill. This analysis starts with consideration of the geology of the area, of which Republic's property is a part, and, among other things, the potential for sinkhole formation in the area. The Cedar Trail Landfill lies within the Bartow Embayment and along the eastern slope of the Lakeland Ridge of the Central Lake District Physiographic Province. This embayment is a large erosional basin partially backfilled with phosphatic sand and clayey sand of the Bone Valley Member. At this location, the top of the Floridan Aquifer is formed by Suwannee Limestone, which consists of white to tan, soft to hard, granular, porous, very fossiliferous limestone with interbedded dolomite. This rock unit is 110-140 feet thick. Atop the Suwannee Limestone sits the Hawthorne Group, which comprises the Arcadia Formation, at the base of which is the Nocatee Member, which is a relatively impermeable sand and clay unit. Atop the Nocatee Member is the Tampa Member, which consists of hard, dense, sandy, locally phosphatic, fossiliferous limestone. The top of this member, which is the top of the Arcadia Formation, is locally referred to as the "bedrock complex," which marks the lower limit of phosphate mining. Atop the Arcadia Formation, still within the Hawthorne Group, sits the Peace River Formation, which consists of phosphatic clayey sand and clayey sand. The lower portion of the Peace River Formation is a relatively impermeable, undifferentiated clayey unit locally known as "bedclay." The Bone Valley Member of the Peace River Formation is mined for phosphate and is locally known as "matrix." Atop of the Peace River Formation are undifferentiated surficial soils, typically consisting of silty sand, clayey sand, and some hardpan and organic soils. These materials are locally known as "overburden." Phosphate mining is prevalent in the area, including, as noted above, much or all of the Cedar Trail Landfill site. Strip mining for phosphate normally removes the entire surficial aquifer, just into the bedclay. Mined areas are then backfilled with overburden spoil soils, clay, waste clay, and sand tailings. After backfilling, the soil strata bear little resemblance to premining strata. Sinkholes are prevalent in the general area surrounding the Cedar Trail Landfill. A sinkhole is a surface depression varying in depth from a few feet up to several hundreds of feet and in area from several square feet to several acres. Sinkholes are typically funnel-shaped and open broadly upward. Sinkholes form when weakly acidic groundwater creates cavities in the calcium carbonate within limestone. Soils above these cavities erode into the cavities. In the area that includes the Cedar Trail Landfill, cover-collapse and cover- subsidence sinkholes predominate among sinkhole types. A cover-collapse sinkhole, which is typically steep- sided and rocky, forms when cohesive soils over a limestone cavity can no longer bridge the cavity under the weight of overlying soil and rock. At this point, the cohesive soils suddenly collapse into the cavity. These are more common in the part of the state in which the Cedar Trail Landfill is located. A cover-subsidence sinkhole occurs due to the gradual lowering of the rock surface as solutioning occurs in the subsurface rocks. This type of sinkhole develops as subsurface soluble rock is dissolved and overlying soils subside into the resulting shallow surface depressions. Regardless of the type of sinkhole, borings into sinkholes will reveal zones of very loose soil sediments that have washed downward into the cavernous voids within the bedrock. This very loose soil zone is called a raveling zone, which starts at the limestone layer, as the overlying soils begin to collapse into the solution features within the limestone. As the loosening works its way upward toward the surface, it eventually results in the subsidence of the ground surface and formation of a sinkhole. Considerable sinkhole activity has taken place in the immediate vicinity of Republic's property. Most visibly, a sinkhole formed in 2006 in 285-acre Scott Lake, 4.5 miles northwest of the landfill. This sinkhole drained the entire lake and destroyed several structures. The Florida Geological Service sinkhole database, which consists of anecdotal reports of sinkhole activity, some of which are unverified, includes 49 sinkholes within five miles of the proposed landfill. Two documented sinkholes have occurred within .17 mile of the landfill--one of which is reported to be 125 feet in diameter and 80 feet deep. Based upon the information contained in the preceding paragraph, Clint Kromhout, a professional geologist with the Florida Geological Survey, opined on August 23, 2009, that the potential for sinkhole formation "within the proposed site and surrounding area" is "low to moderate." Mr. Kromhout does not provide a definition of "low," but part of his opinion is shared by the Golder Report, which agrees that the sinkhole potential on the proposed site is "low." The potential for sinkhole formation in the general area surrounding the proposed landfill, as distinguished from the site itself, is at least moderate. In their Proposed Recommended Order, Republic and Intervenor necessarily concede: "All parties acknowledge that the proposed landfill site is in a general region that has a relatively high frequency of sinkholes as compared with the rest of the state of Florida." It is misleading to characterize the area surrounding the proposed landfill as of low potential for the formation of sinkholes, unless there is another category, like "nonexistent." But characterizing the sinkhole potential of the surrounding area as moderate is not determinative of the likelihood of sinkholes at the landfill's footprint, nor is a site-specific geotechnical investigation mooted by such a characterization. Rather, characterizing the sinkhole potential of the surrounding area as moderate dictates the intensity and scope of the ensuing geotechnical investigation, if the investigation is to provide reasonable assurance of the structural integrity of the proposed landfill. Acknowledging moderate potential for sinkhole formation in the surrounding area, Republic has appropriately relied on three geotechnical reports, including three sets of boring data. The final of these reports, the Hanecki Report, is based on the collection and analysis of boring data, as well as a review of the data and analysis contained in the two earlier geotechnical reports, the Ardaman Report and Golder Report. The boring data reveal that the proposed landfill site features four units. Nearest the surface is Unit 1, which is brown to dark brown, medium- to fine-grained sand with minor amounts of clayey silt. Unit 1 is 0-10 feet thick. Next down is Unit 2, which is tan to gray, medium- to fine-grained sand with increasing silty clay or clayey silt. Unit 2 is 5-10 feet thick and generally marks the upper limit of fine-grained, granular soils (i.e., clayed sands and silty sands). Unit 3 is orange brown to yellow brown, gray and tan silty clay to clayey silt or fine sand and silty clay. Unit 3 is 5-15 feet thick. Unit 4 is gray and tan clayey silt or silty clay with minor amounts of fine sand. This material is very stiff or very dense, and most borings terminated in this unit. The few borings that penetrated this unit suggest that it may consist of dolomitic sandy clays and silts and dolomitic limestone to depths greater than 100 feet below grade. Units 3 and 4 generally mark the upper limits of low permeability/low compressibility soils. The Hanecki investigation comprised two main steps. First, Hanecki retained a subconsultant to perform electrical resistivity imaging (ERI) along 100-foot-wide transects run across the site. Any anomalies revealed by the ERIs were to be followed by standard penetration test (SPT) borings, which permit soil testing at predetermined intervals, as well as a measure of the compressibility of the soils. Compressibility is measured during the soil-testing intervals, during which the drill bit is replaced by a soil sampler. The driller records the number of blows required for a 140-pound hammer falling 30 inches to produce 12 inches of penetration. The value is expressed in N-values, where N represents the number of such blows. Looser soils produce lower N values. Another important piece of information obtained during SPT boring is the partial or total loss of circulation fluid during drilling. While the drill is penetrating soil, a slurry circulates through the borehole to prevent the collapse of the sides of the hole. This slurry is recycled during drilling, but, if the drill encounters a void, all or part of the circulation fluid is lost. The ERI survey revealed no real anomalies because of a narrow range of resistance values. However, taking relatively small differences in resistivity as an anomalies, Hanecki identified 14 features of interest. At each of these locations, Hanecki performed an SPT boring. Because the ERI transects were unable to span the two onsite ponds, Hanecki added two locations for SPT borings adjacent to each side of each pond, for a total of four additional SPT borings. At the request of DEP, Hanecki added a nineteenth SPT boring at Golder site G-11, which had revealed low N-values during Golder's borings. Hanecki extended the borings into "refusal" quality soil, which was defined as soils requiring more than 50 blows of the 140-pound hammer to achieve six inches or less of penetration. All of Hanecki's SPT borings encountered very hard limestone. Among the most significant findings of Hanecki's borings, only one boring, G-11, experienced any circulation fluid loss, and this was estimated at 50 percent. However, it is more likely that this partial circulation fluid loss is due to loosely deposited sands than a void that might be indicative of conditions suitable for sinkhole formation. Not all circulation losses indicate voids that that will result in sinkhole formation. Also significant among Hanecki's findings is a clayey soil, or bedclay, at every SPT boring, which severely limits hydraulic recharge to the limestone. By impeding vertical migration of surface and shallow subsurface water to the limestone layer, this bedclay "greatly inhibits limestone erosion." This bedclay also supports the looser soils above the bedclay and thus prevents raveling, without which sinkholes cannot form. Two borings--G-11 and F3-1--lacked a layer of Unit 3 or 4 soil above the limestone, but Hanecki concluded that the Unit 2 layers above the limestone at these locations contained sufficient clay or clayey sand to serve the same functions of impeding the downward movement of groundwater and preventing the downward movement of loose soils. This conclusion appears reasonable because Unit 2 is the uppermost reach of the finer- grained materials, of which clays and silts are examples when compared to sands. There is obviously some variability in the distribution of finer- and coarser-grained materials within each occurrence of Unit 2 soils. Hanecki's findings indicated intervals of loose soils, sometimes at depth, which typically would suggest raveling zones. At the proposed location, though, these findings do not support raveling due to the underlying bedclay layer and the history of mining, which probably introduced looser soils typically found closer to the surface through the entire 40-foot depth of the mine cut. Based on these findings, the Hanecki Report concludes that, regardless of at least moderate potential for sinkhole potential in the area, the footprint of the proposed landfill has an acceptably low risk of sinkhole development to permit development of the proposed landfill. This is a reasonable conclusion because it is supported by the data collected by Hanecki and his reasoned analysis of these data. Hanecki's conclusion is also supported by the data and analysis contained in the Golder Report and Ardaman Report, which are based on an additional 84 SPT borings, post- reclamation. Only about 12 percent of these SPT borings reached the limestone, and they cover all of Republic's property, not merely the footprint of the proposed landfill. Even so, these borings confirm two important findings of the Hanecki Report. First, they produced data indicative of an extensive bedclay layer intact on Republic's property. Second, the Ardaman and Golder borings reveal only two or three instances of partial circulation loss that, like the sole occurrence of partial circulation loss in the Hanecki borings, are located on Republic's property, but outside the footprint of the proposed landfill. Republic has provided reasonable assurance that the site will provide an adequate foundation for the proposed landfill and sinkholes are unlikely to undermine the structural integrity of the proposed landfill.

Findings Of Fact As a part of its solid waste disposal program, the City of Naples operates a yard trash compost site adjacent to the Gordon River within the city limits. A fifteen (15) acre site has been leased from a private owner, and the lease requires that the City operate the site in compliance with permitting requirements. The site is intended to received only horticultural yard trash. The City picks up such trash in trucks, and delivers it to the site. Cells, or ditches, have been excavated at the site to a depth of approximately six (6) feet. The trash is deposited into the cells. The cells are excavated to a depth below the ground water level, so the trash is placed directly into the ground water. Although only horticultural yard trash is intended to be disposed of at the site, and although the City attempts to enforce this intention, household garbage including food waste frequently finds its way into the cells. The City has been utilizing this site in this manner for approximately fifteen (15) years, and for at least the past ten (10) years has operated under all required local and state permits. The City is presently operating the site in accordance with a permit issued by the Department of Environmental Regulation on December 31, 1976. The permit expires on January 1, 1980. Sometime in February, 1979, the Department first gave notice to the City that the yard trash compost site was not being operated in conformity with all applicable rules and regulations. Specifically the Department advised the City that the site violated the provisions of Rule 17-7.04(2)(a), Florida Administrative Code, because solid waste was deposited within 200 feet of a natural water body (the Gordon River) and Rule 17-7.04(2)(f), because solid waste was deposited in an area where the water table was less than five (5) feet below the normal ground surface. Rule 17-7.04(2)(f) was modified during the course of this variance application proceeding. The rule now requires that solid waste not be deposited directly into the ground water. The City's site neither conformed with the rule in effect in February, 1979, nor with the present modified rule. The Department and the City agreed that the City could continue to operate the site pending the completion of this proceeding, and, until all present cell excavations are filled. Yard trash compost sites such as that operated by the City do not involve as profound a threat to water quality as do more generalized solid waste disposal sites. Nonetheless placing of large quantities of yard trash at or in water bodies will cause infusion of large quantities of nutrients into the water body. The composting or breaking down of yard trash can take place under either aerobic or anaerobic conditions. Aerobic decomposition takes place where vegetation is exposed to oxygen. Anaerobic decomposition takes place where there is no oxygen. If vegetation is covered by water or soil it will not have oxygen. The materials will only partially decompose through a process called fermentation. Such material, when not fully decomposed, cannot be fully compacted nor reduced in volume as would happen with aerobic decomposition. The system utilized by the City of Naples therefore will result in a springy texture to the area. When decomposition takes place above ground, and vegetation is exposed to oxygen, the Vegetation can break down into its primary elements, resulting in a humus material which can be utilized to condition soil, and which will become part of the soil and stabilize the soil. The City's method of disposal introduces very concentrated amounts of organic substances into the ground water. There is thus a large increase in nitrogen and phosphates in the ground water. Placing such large quantities of organic material into the ground water effectively pollutes the ground water. There is a shallow water aquifer below the surface level at the trash compost site. Below this aquifer is a layer of sand, marl and rock which is not highly permeable. Below this layer lies a second aquifer which is an important source of drinking water in the area. Trash at the compost site under the City's present system is deposited directly into the upper aquifer. This water flows either into the Gordon River adjacent to the site, or more slowly permeates down into the lower aquifer. Placing the organic materials into the ground water thus constitutes a serious source of pollution either to the Gordon River, or to the lower aquifer, or to both. Certainly it serves to profoundly degrade the water quality of the ground water. The City has operated two (2) test wells adjacent to the site for the past eighteen (18) months. Results of samples taken from these test sites are inconclusive, and do not reveal that the City's disposal system has caused any pollution whatsoever. This does not mean, however, that no adverse impact could have been detected, or that none has taken place. The City's test wells were not placed so that they would intercept the flow of ground water from the site. Even if they had been so placed, testing has taken place only every six (6) months, and not in a manner so that any viable conclusions can be reached. The Department has recently installed test wells, and although data from them is not complete, it does reveal a definite flow of pollutants from the site to the test wells. Although the flow of ground water will serve to dilute the pollutants to some degree, it is inevitable that the ground water supply itself will be degraded, and that eventually either the waters of the Gordon River or of the lower aquifer will also be adversely affected. Under its present system the City estimates that it will be able to utilize the compost site for eight more years. The City has contended that operating the site as an above ground compost site would effectively cut in half the time period over which the site could be utilized and would increase the cost of maintaining the site by requiring additional equipment, and eventually requiring additional equipment for the transporting of yard trash to a remote site. These contentions are not supported by the evidence. In the first place the City could save money in operating the site as an above ground composting site because it would not be necessary to make excavations. Furthermore, above ground composting of the materials would result in usable compost which could be sold as land fill. This could constitute a source of revenue, and also open the site for additional usage.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is, RECOMMENDED: That a final order be entered granting the variance application filed by the City of Naples with respect to its request to be relieved from the requirements of Rule 17-7.04(2)(a), with conditions imposed as set out in the Department's notice dated June 21, 1979 (DER Exhibit 4). That a final order be entered denying the exemption request filed by the City of Naples with respect to the requirements of Rule 17-7.04(2)(f). RECOMMENDED this 28th day of November, 1979, in Tallahassee, Florida.

The Issue Whether Respondent is in violation of various provisions of Chapter 403, Florida Statutes, as alleged in the Notice of Violation and Orders for Corrective Action dated October 30, 1991.
Findings Of Fact BEI's composting facility is a potential source of water and air pollution and to operate the facility, BEI requires a permit issued by DER. The original permit issued to DER for this facility expired on June 1, 1991 and has not been renewed. Although its permit had expired, BEI was allowed to continue to operate while informal proceedings were ongoing between BEI and DER. When these informal proceedings were terminated by DER on May 20, 1992, further operation of this composting facility was in violation of Chapter 403.707(1), Florida Statutes, and Rule 17-709.400(1), Florida Administrative Code. On at least two occasions while this composting facility was in operation, the air around the facility was polluted by foul odors. During the period following the expiration of BEI's license, BEI failed to submit monthly operating reports and did not conduct quarterly samplings and testing of the compost and submit the testing to DER as required.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Secretary of the DER enter a Final Order finding that BEI has violated Section 403.161(1)(b), Florida Statutes, on each of five counts; and that BEI should immediately cease operation of its solid waste facility, volume reduction plant, until and unless it obtains an appropriate and valid permit from DER and in that regard, BEI shall: Immediately cease acceptance of all materials on the property. In the event that Respondent does not receive a permit from the Department to resume operations at the facility, within 90 days of the effective date of the Final Order, Respondent shall remove all solid waste from the property to an approved solid waste management facility and provide the Department written documentation of its disposal within 30 days of removal. In the event that Respondent does receive a permit from the Department to resume operation at the facility, Respondent shall remain in strict compliance with all terms and conditions of such permit. Within 30 days of the effective date of the Final Order, Respondent shall, if it has not already done so, provide the following to the Department: All records of testing and monitoring conducted on the compost material since January 1, 1990, including daily reports on the temperature and moisture content of compost material, and any testing of compost material conducted prior to distribution. All records documenting application rates of stillage, manure, and leachate to the compost withdrows since January 1, 1990. All records, documenting distribution of composted or mulch material, including amount of compost or mulch material delivered, date of delivery, specific destination of compost or mulch, and intended use of compost or mulch material delivered, since January 1, 1990. All records documenting amount of yard trash received at the facility since January 1, 1990. Within 30 days of execution of the Final Order, Respondent shall make payment to the Department for costs and expenses in the amount of $500.00. Payment shall be made by, cashier's check or money order to the "State of Florida Department of Environmental Regulation". Payment, specifying Office of General Counsel Case No. 91-2006, shall be sent by certified mail to Administrator, Division of Waste Management, Department of Environmental Regulation, 3804 Coconut Palm Drive, Tampa, Florida 33619.

Findings Of Fact The Department (DER) is the regulatory agency of Florida charged with the duty and authority to administer and enforce Chapter 403 and Sections 376.30-376.319, Florida Statutes, and rules and regulations promulgated thereunder. Hendry is a Florida corporation that has been conducting business in excess of 60 years. The two main aspects of its business are the dredging operation and the shipyard. Hendry's site can be loosely described as an industrial site. The shipyard division performs approximately one-half its work for governmental entities, particularly the U.S. Coast Guard, which operations are largely ship refurbishing. Hendry has a Coast Guard certificate enabling it to receive mixtures containing oil and oily water waste. A significant portion of Hendry's ship refurbishing work involves repairing/replacing steel on ships which has deteriorated due to salt water exposure. That work frequently requires cutting, welding and burning. Prior to commencing the refurbrushing work, the ships must be certified as safe. In certifying a ship as being safe, the bilge area is pumped of used oil or waste oil which collects in standing waste water and oil. Also, before that works commences, the ship is defueled. Currently, Hendry's practice is to subcontract the pumping of waste oil from the ships bilge, which waste oil is pumped directly into the tanker truck of the subcontractor. Hendry no longer pumps or stores waste oil on site. In the past, the waste oil and water from the ship's bilge was pumped from the ship through a pipeline from the dry dock across the property to a 10,000 gallon above-ground storage tank. During December 1987, the U.S. Coast Guard observed a fuel spill on the water at Petitioner's facility. Based on that observation, Respondent conducted site inspections of Petitioner's facility during March and April 1988. The fuel spill was occasioned by Petitioner's refurbishment of a tuna boat at its site. Petitioner subsequently received a warning notice regarding alleged violations in its petroleum storage tanks and contamination. The transfer pipeline is of steel construction. Between 1980 and 1984, the pipeline leaked. In 1984, the pipeline was rerun with PVC line and in 1986, it was refitted with 4 inch steel pipe. The 10,000 gallon above-ground tank is located in Area 1. The removal of waste oil occasionally resulted in accidental spills. After 1985, a smaller, above-ground tank was installed adjacent to the 10,000 gallon tank to provide a storage tank for draining off water from the 10,000 gallon tank. The small tank was used to receive only water drained from the 10,000 gallon tank. Prior to installation of the small tank, a retention pond was used to drain water from the 10,000 gallon tank. The retention pond had a 2 foot berm with a visqueen liner. In October 1988, Hendry submitted an EDI Program Notification Application, a prerequisite for EDI reimbursement eligibility, under the program for costs associated with cleanup of certain petroleum contamination. In May 1989, Hendry submitted a document entitled Preliminary Contamination Assessment III Specific Areas--Task IV Rattlesnake Terminal Facility--Westshore Boulevard, Hillsborough County prepared by Mortensen Engineering, Inc. That document included reports of analysis of oil and groundwater samples taken from the site in January, March and April 1989, demonstrating extensive contamination of soil and groundwater including "free product" in monitoring wells MW-2, MW-4 and MW-4A. By letter dated November 9, 1989, the Department informed Hendry of its determination that the facility had been denied EDI reimbursement based on specific enumerated findings. Hendry entered into a stipulation with the Department on October 16, 1990, "regarding the conduct of this case and the basis for denial. " Attached to the stipulation is a sketch of the facility grounds showing a rough division of the area into four separate areas. Area 1 has two waste tanks. One was a large 10,000 gallon closed tank approximately 20 feet high and 12 feet in diameter; the other contained a volume of approximately 1,500-2,000 gallons and was an open tank. Petitioner's practice was to pump bilge in the dry dock area, located west of "Area 2" and direct the waste through underground pipes to the 10,000 gallon tank. The smaller tank was used to "bleed" water from the larger tank. Bilge waste is approximately two-thirds water. Area 2 was the location of Hendry's diesel tank farm. In the stipulation, the Department agreed to withdraw two of the seven specific grounds for the denial, namely denial of site access and failure to report discharges. Likewise, Hendry agreed to withdraw "Area 4" from its application for EDI eligibility. In the stipulation, Hendry was informed of a then recent amendment to Section 376.3071(9), which offered certain applicants who had been earlier determined ineligible for participation in the EDI program, standards and procedures for obtaining reconsideration of eligibility. The amendment required the facility to come into compliance, certify that compliance and request reconsideration prior to March 31, 1991. Additionally, compliance was to be verified by a Department inspection. Pursuant to paragraph 5(b) of the stipulation, these standards and procedures were specifically to be applied to Areas 2 and 3 at the facility. Hendry did not make a written request for reconsideration of the denial of eligibility with respect to Areas 2 and 3 on or before March 31, 1991 or at anytime subsequently. Hendry also did not come into compliance with the underground or above-ground storage tanks system regulations on or before March 31, 1991 in that Hendry failed to register a 560-gallon above-ground diesel storage tank which was onsite on that date as required by Rule 17-762.400, Florida Administrative Code. Hendry also failed to notify the Department of the Hillsborough County Environmental Protection Commission (HCEPC), as the administrator of a designated local program at least thirty days prior to closure of the storage tank system, pursuant to Subsection 376.3073, Florida Statutes. These determinations were made on April 1, 1991 by Hector Diaz, inspector in the HCEPC tanks program. Hendry submitted a registration form for the 560-gallon tank on November 18, 1991, which was of course subsequent to the March 31, 1991 deadline. Hendry stored petroleum products and waste material including petroleum constituents in the above-ground tanks until approximately March 25, 1991 when it initiated tank removal. Hendry's above-ground storage tanks, which were in use at its facility for approximately three years after extensive soil contamination was documented, were without secondary containment. In November 1991, Hendry submitted a document entitled Supplemental Preliminary Contamination Assessment Report, prepared by Keifer-Block Environmental Services, Inc. (Supplemental PCAR). The stated purpose of the study was solely to determine whether hazardous constituents were present in groundwater in Areas 2 and 3. The report included laboratory analysis of groundwater samples taken from the site in August 1991 including monitoring wells located in Area 3. The results of these analysis reflect that Area 3 is contaminated solely with heavy metals, lead and chromium. No petroleum hydrocarbon contamination was detected in Area 3. In the area adjacent to Area 2, seven of eight monitoring wells show chromium or lead contamination. Hendry had, and continues to have, a practice of removing paint from vessels by blasting them with a gritty material known as "black beauty." This practice takes place in the dry dock area near Areas 2 and 3. The waste blast grit/paint chip mixture is vacuumed or shoveled into wheelbarrels or a frontend loader and dumped into an open pile. Occasionally, the waste blast grit/paint mixture is blown about or spilled. Waste "black beauty" has been observed scattered on the ground throughout the facility. Paints sometime contain heavy metals, specifically, lead and chromium. The concentrations and distribution of lead and chromium contamination at the site are consistent with Hendry's long-standing practice of grit-- blasting paint from ships and other vessels and allowing the metal-contaminated paint and waste mixture to fall to the ground. Areas 2 and 3 are contaminated with substances other than petroleum or petroleum products, namely heavy metals. Costs associated with cleanup of lead and chromium are not reimburseable under the EDI program. Paragraph 5(c) of the stipulation allowed Hendry an opportunity to establish eligibility for Area 1 by providing information regarding operating practices at two above-ground storage tanks and a retention pond in that area demonstrating that contamination in that area is predominantly from leaks or unintentional spills of petroleum products from the tanks in that area. Hendry did not provide the required information. On January 27, 1992, Hendry submitted to the Department an affidavit executed by its principal, Aaron Hendry, which Hendry contends fulfills the requirements of paragraph 5(c) of the stipulation. Hendry, the principal who executed the affidavit, is an affiant with a legal and financial interest in the outcome of the EDI eligibility determination. The executed affidavit did not contain specific information with respect to "operating practices at the tanks and retention ponds as required by the stipulation." Specifically, the affidavit is silent as to: What the tanks were made of; When, how and by whom they were installed; What piping, leak detection or overfill protection was associated with them; What repairs or alterations had been made to them; What inventory reconciliation methods were used; Where the materials came from which was put into the tanks; In what manner, how often, and by whom material was put into the tanks; In what manner, how often, and by whom material was removed from the tanks; Disposition of material removed from the tanks; When, how, by whom and why the retention pond was dug; How and for what period of time the retention pond was used; How, often and by whom inspections of the tanks were conducted; When and how leaks occurred and were discovered at the tanks; When and how spills occurred and were discovered at the tanks; What records, including reports to state or local agencies, insurance claims, newspaper accounts, and so forth were kept with respect to leaks or spills at the tanks; What cleanup efforts were made at the time of any leaks or spills; Documentation related to registration of the tanks with state or local agencies; and Documentation with respect to any removal of the tanks, including any description of the condition of the tanks when, or if, removed. For years, the facility's retention pit was used as a "waste pit" namely, a rectangular hole in the ground, approximately 30 feet by 120 feet by 3 feet, for direct discharge of bilge waste piped from vessels at the dry dock area to the waste pit, prior to installation of the storage tank systems. After installation of the large tank in Area 1, the retention pit was used to bleed water from the bilge tank. In the past, the Department has denied eligibility to facilities where a retention pond was used for disposal of petroleum related waste and cleanup of contamination resulting from use of a retention pond. Hendry's affidavit nor other documentation submitted to the Department prior to the EDI redetermination or at hearing establishes that the bilge waste taken from the storage tanks was "a liquid fuel commodity" or recycled into such a commodity. By letter dated June 9, 1992, the Department notified Hendry that reconsideration of its EDI eligibility request for Areas 2 and 3 was denied and that the affidavit of Aaron Hendry submitted with respect to Area 1 did not satisfy the requirements of the stipulation. Thereafter, Hendry challenged the Department's denial of reconsideration and EDI eligibility which joins the issue for this proceeding. The hazardous waste allegation discovered during an inspection of Hendry's facility on April 14, 1988, resulted in a consent order which was entered as a final order of the Department on November 21, 1990. The consent order allowed Hendry an opportunity to demonstrate that not all areas at the facility were hazardous waste disposal areas and, thus, not all areas would be subject to closure and cleanup under the permitting requirements of Subsection 403.722, Florida Statutes and the remediation standards set forth in Chapter 17-730, Florida Administrative Code. To establish appropriate remediation standards and procedures which would be applicable to various areas, Hendry was required to prepare a property diagram designating areas at the property exhibiting any of the following types of contamination: Areas contaminated solely by petroleum or petroleum products or used oil which is not hazardous waste; Areas contaminated by materials which are not hazardous waste; Areas contaminated by the past or present disposal of hazardous waste. The consent order allows contamination assessment and remediation pursuant to the standards and procedures set forth in Chapter 17-770, Florida Administrative Code, for areas contaminated solely by petroleum or petroleum products. (Petitioner's Exhibit 5, paragraph 11.) The consent order requires contamination assessment and remediation pursuant to the Department's corrective action and groundwater contamination cases for all areas at the facility contaminated by used oil which is not hazardous waste or by hazardous material. (Petitioner's Exhibit 5, paragraph 12.) The consent order requires contamination assessment and remediation pursuant to a closure permit with a contingent post-closure plan to close the areas at the facility contaminated by the disposal of hazardous waste. In response to the consent order to delineate areas on the property exhibiting various types of contamination, Hendry submitted the supplemental PCAR. By letter dated March 19, 1992, the Department responded to the supplemental PCAR with a determination that: Area 1 can be assessed and remediated through the standards set forth in Chapter 17-770, Florida Administrative Code. Contamination in Areas 2 and 3 includes heavy metals, which are hazardous materials. Thus, Areas 2 and 3 should be assessed and remediated through the corrective action process for groundwater contamination cases. A hazardous waste facility closure permit application should be submitted for assessment and remediation of Area 4, which, because of the presence of Dichloroethylene, a hazardous substance and chlorinated solvent, should be expanded to include the location of monitoring well MW KBMW-2. Hendry had a practice of cleaning electrical motors by placing such motors on the ground outside the electrical repair shop near Area 4. The motors were sprayed with Trichloroethylene, a waste solvent, which was allowed to runoff into the soil. At the time of this practice, the intention was to leave the solvent contamination unchecked. The Department, pursuant to directives from the United States Environmental Protection Agency (EPA), characterizes the disposition of hazardous waste to the environment as a result of intentional, ongoing industrial practices as "disposal of hazardous waste" within the meaning of Subsection 475.703(21), Florida Statutes and 40 CFR 260.10. The consent order allowed Hendry an opportunity to challenge the Department's determination with respect to delineation of the various areas by filing a petition per paragraph 21 of the order for formal administrative hearings. Hendry filed its petition with respect to the March 19, 1992 letter, which petition is the subject of DOAH Case No. 92-2312.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that: Respondent, Department of Environmental Regulation, issue a Final Order in these consolidated cases concluding that 1) the contamination areas at issue herein are not eligible for EDI reimbursement under Subsections 376.3071(9) and (12), Florida Statutes; 2) that Petitioner cleanup the contamination in Areas 1, 2 and 3 under the guidance document entitled "Corrective Actions for Groundwater Contamination Cases"; and 3) that Area 4 be expanded to include the location of monitoring well MW KBMW-2 and closed through a hazardous waste closure/post closure permit application process.

The Issue The issue in this case is whether the Florida Department of Environmental Protection (agency or DEP) should issue renewal permit No. SO36-26769E to Waste Management, Inc., of Florida (WMI) for the operation of an existing Class I landfill, the Gulf Coast Sanitary Landfill (GCSL) in Lee County, Florida. In the prehearing stipulation, Petitioners specifically dispute whether WMI has provided reasonable assurances: (1) regarding control of off-site odors emanating from the landfill, (2) that it has an approved closure plan, and (3) that leachate from the landfill will not pollute the air and water.
Findings Of Fact The Parties The applicant, WMI, provides waste management services in the state of Florida. These activities include the hauling, transfer, and recycling of solid waste, as well as the construction and operation of landfills. WMI operates GCSL, the facility that is the subject of the permit application, in Lee County, Florida. WCI is a Delaware limited partnership engaged in the business of developing multiple use communities in Southwest Florida. It owns or holds options to purchase lands adjacent to or near GCSL. WCI is also the developer of a planned unit development known as Gateway, which includes residential and commercial properties in close proximity to the landfill. George Sanders owns, personally or as trustee, lands adjacent to or near GCSL. Lee County is a political subdivision of the state with statutory responsibility to plan for and provide efficient, environmentally acceptable solid waste management. Lee County has contracted with WMI to provide solid waste disposal services to citizens of Lee County at GCSL. DEP is the agency of the state with statutory responsibility to regulate and permit landfills such as GCSL. As stipulated, the Petitioners and Intervenor have standing in this proceeding. The Landfill Facility The GCSL is a Class I landfill located at 11990 State Road 82, East, in Lee County, Florida, east of Interstate I-75. The landfill is in a remote, undeveloped area and has been in operation for over 20 years. The Gateway development is south of the landfill. The GCSL includes three parcels of land that have been used for the disposal of solid waste. Parcel 1 and Parcel 2, each about 40 acres, are unlined Class I landfills that have been closed and no longer receive any solid waste. Neither liners nor leachate collection were required when these parcels were constructed and operated. Parcel 3 is a lined Class I landfill that is approximately 80 acres in size. Approximately 50 acres of Parcel 3 are closed and have received final cover. Approximately 30 acres still are used for the disposal of solid waste. Parcel 3 was constructed in phases. In 1984, the Department issued a permit authorizing the construction of the "east hill" and "west hill"--i.e., two separate disposal areas in Parcel 3 where solid waste was placed above grade. In 1989, the Department issued a permit authorizing the construction of the "valley fill"--i.e., a disposal area where solid waste was used to fill in the valley between the east hill and the west hill. Parcel 3 now consists of a single mound of solid waste. As each phase of Parcel 3 was developed, liners and leachate collection systems were installed in Parcel 3 before the commencement of solid waste disposal operations. The liners and leachate collection systems met or exceeded all of the applicable regulatory requirements that were in effect at the time when the waste disposal areas were permitted. Parcel 3 is a well-designed, well-constructed, and well-operated landfill. William Krumbholz is in charge of landfill compliance and enforcement at DEP's district in Ft. Myers. He reports that the GCSL has an "exceptional operation record," and the GCSL is the "best operated Class I landfill" in the district. The GCSL currently is subject to a DEP operation permit (DEP file number S036-180572), as modified. On March 21, 1995, WMI filed an application for a renewal of its operation permit. On or about September 25, 1996, DEP issued its notice of intent to issue the permit to WMI. If issued, the permit would allow WMI to operate the GCSL for an additional five years. See Rule 62-701.330(2), Florida Administrative Code. The landfill is not yet at design capacity and is not expected to reach that capacity during the next five years. WMI desires to renew the operation permit for the GCSL because WMI wishes to continue to provide solid waste management services to Lee County, consistent with WMI's contractual agreement to do so. WMI also wishes to continue operating the GCSL in order to construct Parcel 3 to its final design grades for closure. The design grades will maximize the site's ability to shed stormwater and thus minimize the production of leachate. Continuing to build Parcel 3 to its design grades is environmentally preferable to closing Parcel 3 at this time in its present configuration. Prior to 1994, the GCSL received approximately 1000 tons of municipal solid waste each day. Approximately 90 per cent of the solid waste was household garbage and about 10 per cent was construction and demolition (C&D) debris. The GCSL did not receive industrial waste. The composition of the waste stream changed in August 1994, when Lee County began to operate a waste-to-energy facility. All of the household garbage generated in the incorporated and unincorporated areas of Lee County is taken to the Lee County waste-to-energy facility, where it is burned, and the ash residue is taken to the GCSL. Currently, the GCSL receives only about 450 tons per day of solid waste, which consists of 65-70 per cent ash residue from the waste-to-energy facility, 30-35 per cent C&D debris, and approximately 2-5 per cent municipal solid waste. DEP would allow WMI to accept more solid waste at the GCSL. However, Lee County has the contractual right with WMI to dictate the types of materials deposited in the GCSL, and it is the county's intent to use the waste-to-energy facility, not the GCSL, for the disposal of putrescible wastes. Lee County is contractually obligated to send all of the county's municipal solid waste to the county's waste-to-energy facility, and the county has a financial incentive to do so. Lee County will send municipal solid waste to the GCSL only if an emergency occurs, but even then the county will try to limit the duration and extent of the County's use of the GCSL. Objectionable Odors Objectionable odors at a landfill typically are related to the facility's operating practices (e.g., the size of the working face) and the presence of putrescible, organic materials that degrade and produce gases when they come in contact with water. In this case, the GCSL's operating practices minimize odors. The majority of the waste now received at the GCSL is ash residue, which contains little or no organic material and thus produces little or no odor. In addition, because the GCSL is a "particularly dry landfill," any putrescible waste is not likely to degrade and cause odors. There have been no violations of the DEP odor rules at the GCSL since 1991 and only two instances, in 1987 and 1991, when off-site odors were verified by DEP's inspector. WCI filed odor complaints in 1995, but the complaints were investigated by DEP and the county and found to be invalid. Petitioners presented no evidence of present or anticipated future odor problems at the GCSL. To the contrary, the DEP inspectors and other witnesses established that there are no objectionable odors at the property boundary of the GCSL. WMI's Approved Closure Plan WMI has a closure plan for the GCSL that was approved by DEP when DEP issued the existing operation permit. In the current application WMI asked DEP for authorization to close the remaining portions of Parcel 3 in the same manner that WMI used when closing the other areas at the GCSL. If WMI's request is not granted, WMI may be required to close Parcel 3 with a geomembrane cover or "cap," in accordance with DEP's new requirements for final closure plans. Although DEP's landfill engineer recommends approval of WMI's request for authorization to use an alternate cover material, no proposed agency action has been taken on that request, and DEP will provide notice and a new point of entry for affected persons when the agency decides whether to grant WMI's request. It is, therefore, inappropriate to address the merits of WMI's "alternate procedure" request in this hearing. As provided in Rule 62-701.310(3), Florida Administrative Code, the agency's decision is action subject to a separate Section 120.57, Florida Statutes, proceeding. WMI's closure plan for the GCSL has little significance in this proceeding. The closure plan is used to calculate the cost of closure, which in turn is used to determine whether WMI has the financial resources to pay the cost of closing the landfill. As part of its approved closure plan, WMI previously demonstrated that it has the financial ability to pay the cost of closing the landfill. WMI could be required to spend an additional $1,000,000 to close the GCSL if WMI's request for approval of the alternate procedure is denied by DEP, but it is undisputed that WMI has the ability to pay this additional cost for closure. WMI must submit a revised closure plan at the time when WMI is prepared to close Parcel 3. DEP then will determine again whether the closure plan for Parcel 3 is adequate and in compliance with the DEP standards in effect at the time. (See paragraphs 38-42, "Specific Conditions," appended to the Intent to Issue, WMI Exhibit 4) Leachate Generation Rate at the GCSL While evaluating WMI's request for approval of an alternate closure plan, DEP noted that the amount of leachate collected in Parcel 3 (i.e., approximately 900,000 gallons per year) is relatively low when compared to the amount of leachate generated at other landfills. DEP was concerned that the low leachate collection rate may indicate a problem in the leachate collection system, so DEP requested WMI to evaluate the leachate generation rate at the GCSL in more detail. WMI subsequently presented additional information to DEP. Leachate is defined by DEP as the liquid that has passed through or emerged from solid waste. Rule 62-701.200(50), Florida Administrative Code. Leachate is generated when rainwater falls on the landfill, sinks in, and percolates through the garbage. One of the primary factors reducing leachate at the GCSL is the use of ash as cover material. The ash, which contains lime, undergoes a reaction and "sets up like mortar." It is extremely hard, cannot be penetrated easily, and has a very low permeability. The permeability of the ash is in the same range as the permeability of the barrier layer that is used in a final cover material. The ash "sets up so well" that the surface water runoff is much greater than with a normal cover material. There is an additional, significant reason why Parcel 3 of the GCSL has a low leachate generation rate. Approximately 50 acres of Parcel 3 already have been closed with a final cover which is designed to shed rainwater and thus minimize the production of leachate. Since most or all of the remaining 30 acres of Parcel 3 have been covered with ash, virtually all of Parcel 3 is covered with low permeability materials that minimize leachate generation. Leachate in Parcel 3 also is minimized because WMI employs good operational practices to limit its generation. WMI uses a small working face and stormwater berms to reduce the size of the area where rainwater may infiltrate. WMI maintains aggressively graded slopes that quickly direct stormwater away from the working face and off of the landfill. WMI's "close-as- you-go" strategy means that the waste at the GCSL is covered before it becomes saturated with rainwater. Specific conditions in the Intent to Issue require that these practices continue. After DEP requested WMI to evaluate the leachate generation rate in Parcel 3, WMI hired a firm to clean the inside of all of the pipes in the leachate collection system in Parcel A television video camera was used to visually inspect the inside of all of the pipes. This work confirmed that "at least 99.9 per cent" of the leachate collection pipes are clean and functional. WMI promptly repaired the leachate collection pipes in two small areas where there was blockage due to a crushed riser and a valve that was left closed. It is highly unlikely that leachate is mounding up inside the landfill or overtopping the perimeter berm that surrounds Parcel 3. The leachate levels inside Parcel 3 generally are and historically have been less than two feet. The leachate levels at the GCSL do not threaten the liner's integrity. The pipes are working, and no seepage has been observed through the side slopes. WMI verified that the liner and leachate collection systems in Parcel 3 were constructed properly and in accordance with the DEP-approved design. Construction Quality Assurance reports were prepared by professional engineers when the liner systems were installed in Parcel 3. In these reports, the engineers certified that each section of the liner was installed, inspected, and tested appropriately to ensure that there are no holes in the liner. Where necessary due to failed tests, the reports reflect that repairs were made before any waste was deposited. The HELP Model In response to DEP's questions about the leachate generation rate at the GCSL, WMI's staff attempted to calculate the rate by using a computer program referred to as the HELP model. WMI initially ran the model with default input values which produced a predicted rate of 7.5 million gallons per year (MGY). WMI questioned the validity of the model results, but submitted the results to DEP because it was the best data then available. Given the discrepancy between the model results and the actual field data, WMI hired a nationally recognized consulting firm, Post, Buckley, Shuh, and Jernigan (Post Buckley), to perform a more refined analysis using the HELP model. The HELP model is used to calculate water balances at landfills. The model calculates the amount of water that will move across, into, and through landfills under different conditions. The model is a useful tool for comparing the performance of two alternate landfill designs, but it has limited value when used to predict the actual performance of an operating landfill. The model can be run with default values or with site- specific information. However, the model is designed to be conservative and overpredict the actual leachate generated. In its application of the model, Post Buckley adjusted several input parameters to reflect the actual conditions at the GCSL. Most significantly, Post Buckley adjusted the input parameters for the moisture content of the waste in the GCSL and for the U.S. Soil Conservation Service's (SCS) Curve Number. These adjustments were "reasonable and well-considered." The HELP model assumes that the solid waste in the landfill is at field capacity--i.e., saturated with rainwater. However, it is well established that the solid waste in landfills is not saturated. At the GCSL, the ash cover material and WMI's "close-as-you-go" practices would reduce the likelihood that the waste would be saturated. Indeed, Post Buckley's on-site inspections revealed that the GCSL is a "particularly dry landfill." The users' manual for the HELP model indicates that the Curve Number should be adjusted in certain cases to account for increased stormwater runoff that will occur during short duration, high intensity storms. The default value is used in areas where the rainfall occurs over a 24-hour period. In this case, Post Buckley concluded that the SCS Curve Number should be adjusted because the GCSL receives about 54 inches of rainfall annually during approximately 90 short duration, high intensity storms. Accordingly, Post Buckley adjusted the model's input parameters to increase runoff by 23 per cent of precipitation. Post Buckley's adjustment to the Curve Number and runoff value is consistent with the findings contained in a report by Benson and Pliska, which in the opinion of WMI's expert is the best study performed to-date on the calibration of the HELP model and which is similar or equivalent to the Peyton and Shroeder calibration relied on by Petitioner's expert. Post Buckley ran the HELP model with three different sets of conditions. In one run, Post Buckley adjusted the input parameter for the moisture content of the waste and calculated an leachate generation rate of 100,000 gallons per year. In the second run, Post Buckley adjusted the Curve Number and calculated a rate of 1.3 MGY. In the third run, Post Buckley adjusted both the Curve Number and the moisture content and calculated a rate of zero gallons per year. Given Post Buckley's landfill experience and its knowledge about the operational practices at the GCSL, the ash used as cover material, the climatological conditions in southwest Florida, and the limitations of the HELP model, Post Buckley concluded that 1.3 MGY is a reasonable estimate or approximation of the actual leachate generation rule for Parcel 3 of the GCSL. The leachate generation rate for the GCSL also has been evaluated by other witnesses. Mr. Joe Fluet calculated that approximately 960,000 gallons to 1,030,000 gallons of leachate are generated annually in Parcel 3. Mr. Fluet is a nationally recognized landfill expert who was selected by DEP to serve as the chairman of a technical advisory group that helped DEP develop the current DEP landfill rules. Mr. Fluet's conclusion is consistent with the leachate collection data for the GCSL, the Post Buckley analysis, the measurements of leachate in the sumps at the landfill, and his own personal observations of the landfill and WMI's operational practices. It is unlikely that leachate generation in Parcel 3 is as high as 2.0 MGY. This rate would produce about three feet of leachate on the liner. WMI's field data show that the "head" (depth) of leachate over the liner in Parcel 3 generally is less than two feet. By comparison, Post Buckley's estimated rate of 1.3 MGY would produce about 1.8 to 2.5 feet of leachate over the liner, which is more consistent with WMI's field data. Petitioners also attempted to calculate leachate generation for Parcel 3 by running the HELP model. Using default values, Petitioners calculated a rate of approximately 7 MGY. Petitioners also ran the model after adjusting several input parameters. Among other things, Petitioners decreased the slope from 20 per cent to 4 per cent, and Petitioners increased runoff by 30 per cent, as compared to the default value. With these adjustments, Petitioners calculated a rate of 4.2 MGY. The various experts' calculations with the HELP model produced leachate generation rates of 0 to 7.5 MGY. The magnitude of the range reflects the limitations of the model and underscores the need for sound professional judgment when adjusting the input parameters. In this case, the most persuasive and credible testimony was presented by Mr. Bonaparte, a recognized landfill expert who is assisting EPA with its efforts to calibrate the HELP model, and Mr. Fluet. Consistent with their testimony, the greater weight of the evidence indicates that the leachate generation rate for Parcel 3 of the GCSL is most likely to range between 960,000 gallons and 1.3 MGY. The Petitioners' calculated range of 4.2 to 7.0 MGY is not credible. Even the low end of Petitioners' range is more than twice as much (2.0 MGY) estimated by any other witness. In addition, Petitioners' entire range of calculated leachate generation rates is inconsistent with the other evidence of record, as described below. Petitioners' leachate generation calculations were prepared by Marcus Pugh, who has not visited the GCSL nor performed any site specific field work concerning the GCSL. Mr. Pugh had never used the HELP model before to predict the generation rate of an operating landfill, but rather has used it as others commonly do, to size and design facilities. Although Mr. Pugh initially criticized Post Buckley's calculation of the slopes at the GCSL, he subsequently conceded that the HELP model results obtained by Post Buckley are independent of slopes. Missing Leachate? Based on their HELP model calculations that Parcel 3 actually is generating 4.2 to 7.0 MGY of leachate and since WMI is collecting 900,000 gallons per year, Petitioners speculate that there is "unaccounted for" or "missing" leachate (i.e., 3.3 to 6.1 MGY), which must be leaking through the GCSL's liner or seeping out of the sides of the GCSL, or both. Petitioners' allegations, however, are not supported by the evidence of record, which favors a finding that the facility is simply not generating the vast amounts of leachate predicted by Petitioners. The liner and leachate collection systems under Parcel 3 were "state-of-the-art" and in full compliance with all of the applicable DEP rules at the time of their installation. These systems were installed properly, in accordance with standard quality assurance procedures, as certified by a professional engineer. Mr. Bill Krumbholz, the DEP inspector, personally witnessed the installation of portions of the liner. Mr. Fluet also was personally involved with the certification for the landfill. Even the Petitioners' witness, Mr. Pugh, conceded that he had no concerns about or disagreements with the certifications for Parcel 3. Thus, there is no reason to believe that the liner or leachate collection systems were damaged at the time when they were installed. Petitioners theorize that the liner in the GCSL may have been damaged after it was installed, but Mr. Pugh readily admits that this contention is based on "pure speculation" based on the notion that a minimum wage laborer on heavy equipment might damage the liner. Petitioners presented no direct or credible evidence to support their contention. After the completion of construction and the commencement of operations large scale breaches of a landfill liner are not a common or even occasional occurrence. As part of its standard management practices, WMI places a four-to six-foot thick "fluff" layer of select household garbage over any new landfill liner system. The fluff layer is used to protect the liner and ensure that the liner is not accidentally damaged. This WMI policy was followed when the liners were installed in Parcel 3 of the GCSL. As a result, there is no reason to believe that the liner in Parcel 3 was damaged after installation. There is no circumstantial evidence to support Petitioners' claims. Since 1976, WMI has monitored the water quality at the GCSL in accordance with a DEP-approved ground water monitoring plan, which is designed to detect any significant leakage from the landfill. No groundwater quality violations have been recorded at the GCSL. However, if one were to assume that Petitioners' theory is correct, then one also would have to assume that over the last five years approximately 16.5 to 30.5 million gallons of leachate have leaked through the liner in Parcel 3 and entered the adjacent groundwater, but somehow have evaded detection in the monitoring wells. Respondents' witness Mr. Fluet calculated that a maximum of 56,000 gallons per year of leachate might possibly leak through the liner system in Parcel 3. His calculation conservatively assumed that there may be as many as ten 0.1 cm2 holes in each acre of the liner in Parcel 3. Petitioners have offered no credible theory that would produce a leakage rate of several million gallons per year. To create a leakage rate of even one million gallons per year, there would have to be at least ten and perhaps dozens of large holes in the liner. Each of the holes would need to be 10-feet long and several inches wide. However, large holes or breaches in a liner system normally are identified and repaired during the installation and quality assurance process. There is no evidence of poor quality assurance or poor operational practices at the GCSL to support Petitioners' speculation. WMI witness, Rudolph Bonaparte, has never encountered a situation where there was evidence of the kinds of "major flaws" that would be necessary to generate the leakage rates hypothesized by Petitioners. Mr. Fluet also was unable to identify any plausible scenario that would support Petitioners' theory. Petitioners' witness, Mr. Pugh, conceded that he has never worked on a lined landfill where 4-to 7-MGY of leachate leaked through the liner. Petitioners questioned whether settlement would affect the liner or leachate collection systems in Parcel 3. Since ash is denser than MSW, the disposal of ash in the GCSL may affect the settlement of the subsurface soils to some extent, but there will be no shearing or failure of the liner due to any differential settlement. The amount of differential settlement that may occur would be extremely small. Settlement could create a 1000 gallon "puddle" of leachate in the valley fill portion of Parcel 3, or the slope in some portions of the leachate collection system may flatten, but these are relatively minor impacts. Conversely, increased settlement in the base of Parcel 3 would help improve the overall drainage of the east hill and the west hill areas. Petitioners contend that the "unaccounted for" leachate may be escaping from the GCSL through side slope seepage, but this theory is not supported by any direct or credible evidence. It was undisputed that any significant amount of side slope seepage from a landfill is readily apparent. Leachate seeps typically "look ugly and smell bad." When seeps occur, the soil is discolored, the vegetation is killed, and there is sheering, gullying, rilling, and other signs of erosion. There has been no side slope seepage from Parcel 3, as established by numerous site visits and personal observations of the DEP staff, county representatives, and other witnesses. Petitioners' witnesses have not observed any side slope seepage at the GCSL. Although Petitioners noted that there are discolored areas on Parcel 3, those are the areas where WMI recently excavated into the sides of the GCSL to complete the repairs to the leachate collection system. The leachate would have to mound up inside the landfill before there would be the amount of seepage predicted by Petitioners. This mounding would create tremendous head pressure in the cleanout pipes. However, no such pressure has been found in the cleanout pipes at the GCSL. Petitioners suggest that leachate may be seeping from the toe of Parcel 3 into the drainage ditch that leads to the stormwater retention pond. Again, the evidence does not support this hypothesis. The liner in Parcel 3 goes over the top of a berm which is built completely around the perimeter of Parcel 3. The berm and the liner rise 3 feet above the base of the leachate collection system. Leachate could not seep from the toe of Parcel 3 unless the leachate level rose above the functioning leachate collection pipes, avoided being drained away by the leachate collection system, and then flowed uphill over the berm. Even if the leachate went up and over the berm, the leachate would enter the ditch from the top of the berm, where it would be readily visible to site inspectors as side slope seepage. No such seepage has been observed at the GCSL, even when people were looking for it. Ground Water Monitoring at GCSL There are three aquifers underlying the GCSL: (a) the surficial water table aquifer; (b) a sandstone aquifer; and (c) the Hawthorne formation. Each of the aquifers is separated by a low-permeability, confining layer of varying thickness. The confining layer below the surficial water table aquifer is between 40 and 80 feet in thickness. Based on field data and reports of other scientists, including Petitioner's expert, Thomas Missimer, hydrogeologist Martin Sara derived a vertical flow rate of approximately 0.1 feet per year. At this rate, ground water would take approximately 40 to 50 years to move vertically downward through the confining layer. Petitioners contend that the GCSL is affecting the surficial water table aquifer. The surficial water table aquifer contains fresh water and is used extensively as a source of potable water in Lee County, but not in the area of the GCSL. Ground water samples collected from the surficial water table aquifer on Petitioners' property had average total dissolved solids (TDS) concentrations of approximately 500 mg/l. Similar TDS values have been reported for the surficial water table aquifer in the area surrounding the GCSL. In general, the regional groundwater flow in the vicinity of the GCSL is to the northwest. There is a northwesterly flow from WCI's property onto the GCSL that is consistent year after year and during all seasons. Extensive historical monitoring data for the site confirm that the ground- water flow under the GCSL also primarily is to the northwest, but with some likely localized flow to the west, at least during special events such as landfill dewatering in 1982. The only significant exception to this trend occurs in the area of the stormwater retention pond, where the groundwater usually flows radially outward in all directions. Groundwater monitoring began at the GCSL in 1976, when the facility opened. The groundwater monitoring system at the GCSL has complied with or exceeded the DEP requirements at all times since 1976. Currently there are seven groundwater monitoring wells, each approximately 30-feet deep, in the surficial water table aquifer at the GCSL. These wells surround the perimeter of the GCSL. At the final hearing, Lee County attempted to address concerns about the groundwater monitoring program for the GCSL by agreeing to pay for the redevelopment and installation of additional groundwater monitoring wells. Lee County and WMI stipulated that two existing groundwater monitoring wells (wells 14-S and 18-S) will be redeveloped and a new ground water monitoring well will be installed in the surficial aquifer between existing wells 20-S and 21-S. The two redeveloped wells and the new well will be sampled on a semiannual basis for chloride and the field parameters of pH, specific conductivity, field turbidity, and temperature for the life of the permit. The monitoring may be discontinued if the GCSL closes. The monitoring well network at the GCSL is adequate to monitor the type of area-wide plume that might originate from the GCSL. The evidence demonstrates that any holes in the liner in Parcel 3 are likely to be small and spread widely across the entire site. Although the plume from a single hole may be narrow and elongated, the plume from the entire landfill would be approximately 2400-feet wide. Under most if not all plausible scenarios, leachate leaking out of the liner beneath Parcel 3 will move with the regional groundwater flow toward the monitoring wells located along the western and northern perimeters of Parcel 3. Potential leakage from Parcel 3 will be pushed toward these monitoring wells by the regional groundwater flow and the radial flow from the retention pond. DEP has concluded and the evidence confirms that WMI's groundwater monitoring plan, as modified by Lee County's stipulation, is protective of the environment and satisfies all applicable DEP requirements. Under the facts of this case, it is not necessary to add any additional monitoring wells or otherwise modify the groundwater monitoring plan, except as stipulated by Lee County. It was undisputed that the leachate generated at the GCSL is and always has been "very weak" in comparison to the leachate from other landfills. The leachate contains relatively few contaminants and has low contaminant concentrations. The GCSL's leachate has few volatile or hazardous constituents. It also was undisputed that there have been no violations of DEP groundwater standards detected in any of the groundwater monitoring wells at the GCSL. There have been one- time exceedances or anomalies, but such events do not constitute a violation of the DEP standards. Chloride In the Ground Water Chloride is present in the GCSL's leachate. Over the last ten years, the average chloride concentration in the leachate has been 1021 parts per million (ppm), and the highest concentration has been 2070 ppm. The Department has no primary (i.e., health-based) groundwater quality standard for chloride. The only groundwater quality standard for chloride is a secondary standard of 250 ppm. Secondary standards are intended to address concerns about odor, taste, and aesthetics. If chloride concentrations become too high in drinking water, people simply stop drinking the water before there are any health implications, because the water is too salty. WMI evaluated Petitioners' claim that chloride leaking from Parcel 3 may affect the water quality on Petitioners' property. First, WMI performed a mass balance calculation and concluded that the maximum rate of leakage from Parcel 3 would increase the chloride concentrations beneath the landfill by only 7 to 14 ppm. WMI then used a dispersion model and determined that the maximum leakage rate would increase the chloride concentrations in the groundwater only 3.5 ppm at a distance of 100 feet from the landfill. This increase in chloride could not be distinguished from the existing background concentrations in the groundwater. WMI also analyzed the groundwater data to determine whether the GCSL is causing an increase in the chloride concentration measured in monitoring well 21-S. WMI plotted the data on trilinear diagrams, consistent with techniques that have been commonly used by hydrogeologists for many years. The trilinear diagrams clearly show that the increased levels of chloride in monitoring well 21-S are not caused by the leachate from the GCSL. The trilinear diagrams do not identify the source of the chloride found in monitoring well 21-S. However, it appears that the chloride originated from a source of "brackish" water. There are several potential sources of the chloride in well 21-S. In the past, there was an irrigation well on WCI's property that pumped water with high chloride concentrations and created a large plume of chloride-enriched groundwater on WCI's property. Historic groundwater monitoring data indicate that the chloride plume was approximately 6000-feet wide and flowing towards the GCSL. This large plume may have reached the GCSL and affected the water quality in well 21-S. There also were irrigation wells located on the site of the GCSL that may have contributed to the chloride concentrations in well 21-S. Historic water quality data indicate that these irrigation wells produced elevated chloride concentrations in the groundwater at the GCSL. Petitioners' Stormwater Data On May 12, 1997, Petitioners collected samples of the water in the stormwater retention pond at the GCSL. Petitioners also collected a sample of the water in a concrete culvert that carries stormwater runoff from Parcel 3 to the retention pond. The samples were collected during a severe rainstorm when it was "raining cats and dogs." Based on these samples, Petitioners speculate that the "unaccounted for" leachate is entering the stormwater retention pond via a perimeter drainage ditch and the concrete culvert. This speculation is not supported by the evidence. Leachate generated in the GCSL has an ammonia-nitrogen concentration in the range of 700 to 800 ppm. The stormwater collected from the culvert pipe had an ammonia-nitrogen concentration of 1.7 ppm. The disparity between these two values belies the possibility that the stormwater in the ditch contains leachate from the GCSL. Although Petitioners contend that ammonia-nitrogen in the leachate could be oxidized while flowing in the ditch, it would be virtually impossible for the oxidation of stormwater in the ditch to reduce ammonia-nitrogen levels from 700 or 800 to 1.7 ppm. WMI's extensive experience with leachate has demonstrated that it is "very difficult" to treat and reduce the ammonia-nitrogen levels in the leachate through volatization and aeration. The water collected by Petitioners in the culvert had a chloride concentration of 2900 ppm, which significantly exceeds the highest chloride level ever found in the GCSL's leachate (2070 ppm). The pH in Petitioners' sample (8.87) also was notably higher than the pH found in the landfill's leachate (e.g., 7.20 in WCI Exhibit 14). The disparity between the values found in Petitioners' sample and the values found in the landfill's leachate suggests that the Petitioners' sample is not representative of leachate from Parcel 3. Stormwater flowing over the ash residue on the top of Parcel 3 is the most probable source of the elevated chloride and high pH found in Petitioners' sample. The ash at the GCSL has elevated chloride concentrations. It also has high pH, due to the addition of lime at the waste-to-energy facility. Both WMI's witness, Mr. DeBattista, and Petitioner's witness, Dr. Missimer, saw stormwater washing over the ash and entering the stormwater conveyance system that led to the culvert where Petitioners' sample was collected while Petitioners were at the GCSL collecting samples. Petitioners noted that the water in the stormwater ditch was discolored. However, Petitioners' photograph of the site (WCI Ex. 10) reveals that the water in the ditch is the same color as the mulch (compost) that is stockpiled on Parcel 3 and used for intermediate cover. During Petitioners' site visit, stormwater was flowing over the mulch on Parcel 3 before entering the stormwater ditch. Dr. Missimer conceded that the color of the water in the ditch could be caused in part by the mulch and stormwater runoff. Dr. Missimer raised a number of other issues about the GCSL. He claimed that the sediments in the stormwater retention pond have elevated metals concentrations, but he does not contend that the metals concentrations in the sediments violate any applicable DEP standard. He also does not contend that the metals are leaving the site. Dr. Missimer noted that there was "foam" in a stormwater ditch. However, Petitioners presented no competent evidence about the source of the foam or its chemical composition. Finally, Dr. Missimer heard gas escaping from a cleanout pipe at a different location on the landfill, but there were no odors associated with it. There is no evidence to demonstrate that gas in the riser pipes is a cause for concern. In response to Petitioners' chloride data, WMI is taking steps to manage its stormwater better. WMI has placed intermediate cover over 10 acres of exposed ash, thus reducing the potential for the rainwater to come in contact with the ash and convey chloride into the stormwater management system. WMI also is determining whether it should remove a culvert that served as a conduit for the runoff from Parcel 3 to the retention pond. It was undisputed that the GCSL is an "existing installation," as that term is defined by DEP. Parcels 1 and 2 of the GCSL were unlined and were reasonably expected to release contaminants into the ground water on or before July 1, 1982. The GCSL has operated consistently with the applicable DEP statutes and rules relating to groundwater discharges in effect during the time of its operation. Since the GCSL is an existing installation, WMI is entitled to a zone of discharge that extends to WMI's property boundary. The groundwater within the zone of discharge is not required to meet the DEP water quality standards. Modifications to Conditions of Draft Permit and Summary of Findings In addition to the modification to the ground water monitoring plan described in paragraph 59 above, WMI has requested and DEP has agreed to make minor changes to the language in Specific Conditions 10, 19, 32, 38, and 45(e) of the draft permit. These changes relate respectively to gas monitoring, daily cover, acceptance of C & D debris, data to support the alternate procedure request for final cover, and the zone of discharge. These modifications are reasonable, supported by the evidence, and consistent with DEP rules. Moreover, WMI has provided reasonable assurance of compliance with all applicable DEP rules for continued operation of the GCSL. As amply demonstrated in this proceeding, highly competent professionals can disagree. Petitioners' witness Dr. Missimer, has had years of experience in studying the hydrogeology of Lee County and the area of the landfill and Gateway. His data collected during the development of Regional Impact Studies for Gateway have been relied on by DEP and others. His conclusions, however, regarding enormous amounts of leachate escaping the landfill are simply not supported by the results of years of monitoring the landfill's operations. With continued monitoring, the applicant should be permitted to continue to operate.
Recommendation Based on the foregoing, it is hereby RECOMMENDED: That the Department of Environmental Protection enter a Final Order approving Waste Management, Inc., of Florida's application for a permit renewal to continue to operate the Gulf Coast Sanitary Landfill, subject to the parties' stipulation regarding additional groundwater monitoring wells and subject to the revisions to the draft permit that are described herein.

The Issue Whether Beker Phosphate Corporation should be granted a hermit to construct an industrial waste water facility pursuant to chapter 403, Florida Statutes. By application, dated April 8, 1975, Beker Phosphate Corporation (hereinafter Beker) , sought a permit to construct an industrial waste water facility in Manatee County, Florida, from the Department of Pollution Control (now and hereinafter DER) . The application was received on April 11 and, after advising Beker that the application was incomplete a meeting was held on May 9th between DER and Beker representatives with the result that Beker filed a new application dated June 11, that was received by the DER in July. Further meetings were held in the fall of 1975 and additional in formation was received as to the application. On December 16, 1975, DER secretary. Jay W. Landers, Jr., issued a Notice Of Intent To Grant A Permit With Conditions. The conditions were unspecified in the letter of intent (Exhibit 1.) Subsequently, on December 23 and December 24, 1975, Sarasota County (hereinafter Sarasota) and the Town of Longboat Key (hereinafter Longboat Key), respectively, filed petitions with the DER alleging that their substantial interests would be adversely affected by approval of the permit application and setting forth in their petitions certain disputed questions of fact for determination. After a prehearing conference, Amended Petitions were filed by those parties to clarify and expand on such questions of fact and to resolve procedural matters. Additionally, during this period, George Browning, III, of Sarasota, Florida was granted status as an intervenor.
Findings Of Fact Beker proposes to construct a phosphate rock mine and beneficiation plant on a tract of approximately 11,000 acres in a predominately agricultural and ranching area of Manatee County about 10 miles from Myakka City, Florida. The mining will be performed by two dredges. One will mine overburden and return it to the mined-out area and the other will mine phosphate rock matrix which will be pumped to the beneficiation plant. The plant will consist essentially of two circuits. The first is a washer where the matrix pumped from the dredging operation is partially cleaned of clay and fine sand, and the coarser phosphate particles "pebbles" are separated as a product. The "fines" from the washing operation consist of small phosphate rock particles, sand, and clay. This mixture will be treated in the second section of the plant by "flotation" methods to recover the small phosphate rock particles as a product. During initial operation, the sand and clay will be stored in a temporary waste material storage area, but as the mining proceeds and the dredge pits open up, the sand and clay material will be pumped back to the dredge pits so that sand, and overburden will be mixed and redeposited to reclaim the land. Approximately 8 million gallons of fresh water per day will be drawn from the Floridian aquifer to be used in the flotation circuits. From the plant the water flows in two types of streams--one containing sand suspended in water and one containing clay suspended in water. Both streams flow into a settling pond surrounded by an earthen dam where sand and clay solids settle to the bottom. The clarified water is then decanted through six spillway structures into a hydraulic recirculation ditch outside the dam and flows back to the plant for re-use. The ponds and canals that make up the hydraulic circuit are planned to have sufficient capacity to contain rainwater falling on the site and pond system during the wet season when there are heavy rainfalls (approximately from May to September). Excess water will be decanted from the hydraulic recirculation ditch through a structure into a pipe and then discharged into Wingate Creek. The settling pond will occupy approximately 225 acres and its capacity will be about 8,458 acre- feet. The pond itself can be used to act as a reservoir and water can be built up in the pond during periods of high rainfall. It will not be necessary to release the water at any particular time. It can be released at will when the effluent contains a minimum of pollutant materials (Exhibit 1). Matrix is an unconsolidated mixture of phosphate pebbles and boulders of partly phosphatized limestone, quartz and clay. The washing operation removes unwanted oversized material and fine clays. The purpose of the flotation plant is to recover fine phosphate rock that might otherwise be lost. In the flotation process, flotation reagents, including sulfuric acid, number 2 fuel oil, tall oil, sodium hydroxide, and amines are used for treatment. The wastes are then moved to the settling pond where over a period of time the "slimes", (sands and clays) will settle to the bottom forming an impervious layer which will seal the pond. The settling process removes more than 90 percent of the contaminants from the influent. The coarser clay particles settle first and many of the fine particles settle in a process called "flocculation" by which electrical forces bring the particles together. However, some of the particles will not flocculate and remain suspended in the water. These extremely small particles constitute the total suspended solids that remain in the effluent when it is discharged from the settling area. They probably will not settle out entirely during their course from Wingate Creek into the Myaaka River and eventually to the Gulf of Mexico. However, even if it were assumed that such materials would settle somewhere between the point of discharge and Charlotte Harbor, over the entire 20 year proposed life of the mine they would form a deposit much less than 1/10th of an inch. Although it is technically possible to treat water to the degree that it would result in distilled water, realistic concepts of treatment establish that an additional settling or "polishing" pond for the proposed facility might not improve the quality of the wastewater finally discharged in state waters to any appreciable degree. Alternative proposals for the reduction of pollutants by additional processing, such as the intentional growth of water hyacinths in settling areas or use of chemical coagulants would result in creating other waste materials and thus be counterproductive (Testimony of Bromwell; Exhibit 1). The applicant's discharge of wastewater to Wingate Creek will average approximately 3.19 million gallons per day. However, since discharge will be effected primarily during periods of excessive rainfall, actual discharges can reach a maximum of about ten million gallons per day during this period. The effluent contained in such discharge will meet the test of at least 90 percent removal of organic and inorganic wastes specified by Rule 17-3.04(1), Florida Administrative Code, when measured by the influent into the settling pond and the effluent leaving that area. This treatment, however, will not produce an effluent equivalent to that produced by the "highest quality municipal waste treatment." The highest degree of treatment that has been reached by municipalities is "advanced waste treatment" as defined in Rule 17-3.04(2)(b), Florida Administrative Code. The water quality characteristics of the effluent will meet the standards of Rule 17-3.05 as to concentrations of those pollutants reasonably anticipated to be fond in the wastewater based on samples taken where the waters are discharged into Wingate Creek (Testimony of Gilgallon, Davis, Edwards, Heinzman, Bromwell, Bartow, Wellford, Exhibit 1). In preparing the application, no consideration was given to the need of meeting treatment standards for highest quality municipal waste treatment or advanced waste treatment. Neither did the recommending official of the DER, Mr. Edwards, then Regional Administrator for the Southwest Region, consider this standard because he had been advised by the DER legal staff that Rule 17-3.04(2) did not apply to Wingate Creek since it was not a tributary to one of the bodies of water listed in subparagraph (c) of the rule 17-3.04(2). This determination was based upon Resolution No. 74-83, September 17, 1974, of the Florida Pollution Control Board that was issued after legal challenges had been made to an interpretation by the Department of Pollution Control legal staff that Rule 17-3.04(2) required advanced wastewater treatment for industrial waste discharges. The Board, in its resolution, determined that since evidence had not been taken concerning treatment standards for industrial waste discharges at the time of adoption of the effluent standards for sanitary waste contained in Rule 17-3.04(2), the advanced wastewater treatment standards in the aforesaid rule would not be enforced against industrial dischargers pending full hearings on a new Rule to clearly express the Board's intent in this regard (Testimony of Gilgallon, Edwards; Exhibit 1). Special conditions that the Southwest Region, Department of Environmental Regulation, recommends should be attached to any issuance of a construction permit, other than standard conditions and those relating to other types of permits, are as follow: Approval by DER prior to the construction of any above grade phosphatic clay storage facility other than the initial settling pond. Removal efficiencies for oil and grease shall be a minimum of 90 percent and shall not exceed 14 milligrams per liter measured in the discharge effluent. Discharge effluent to Wingate Creek shall meet the water quality standards of Chapter 17-3.05(2) at the point of discharge prior to mixing with the receiving stream. Further treatment of the discharge will be required in the event compliance with proviso (c) above cannot be achieved or significant degradation of the receiving stream occurs as determined by the DER. In addition to required routine monitoring, a detailed analysis of the untreated and treated wastewater to be conducted once on representative samples during (1) month of July and (2) month of February. Such analyses shall, as a minimum, include all the parameters listed in 17-3:05(2). Applicants shall conduct an investigation into total retention possibilities of the effluent including, but not limited to, the following areas: recharge wells retention and storage of excess water during the "wet" season with subsequent reuse during the "dry" season for process and/or irrigation purposes. A report of these investigations shall be submitted prior to submission of operation permit application The location of monitoring wells shall be down gradient from the settling pond. Detailed proposal, subject to the DER approval, regarding exact location and number of wells to adequately ascertain the impact of seepage to be submitted no later than 90 days prior to commencement of operation. Bond to be posted for damages that may result from a clay settling area dam failure. Oral and written communications from the public were received at the hearing and included the following: Announcement by the County Attorney, Manatee County, that the county did not plan to appeal the DER Notice of Intent to Grant the permit (Statement of E.N. Fay, Jr.). The Division of Recreation and Parks, Department of Natural Resources, fears that the construction of the phosphate mine up-stream from the Myaaka diver State Park poses a serious potential threat to its aquatic habitat due to the possibility of a dam failure. It also fears that pollutants from the project will tend to settle as the river waters flow through the two lakes in the park. It therefore, opposes the construction until assurance can be given that proper safeguards have been taken to prevent such problems (Testimony of Alverez). The Longboat Key Garden Club believes that the project would involve too much water consumption and also that phosphate mining should be halted until further government studies are made to assure that the safety and health of the populace and the environment will not be endangered through polluted runoff and phosphate spills (Testimony of Monroe). The Save Our Bays Association in Manatee County has collected petitions from citizens in Manatee County requesting a referendum on a ballot this November for or against phosphate mining. The Association believes that such a vote should be taken before final decision is made on the subject. Its spokesman fears that if the quality and quantity of the drinking water is disrupted, it will interfere with continued tourist trade (Testimony of Howard Greer). The Palma Sola Parks Association opposes the Beker Application until there is greater assurance of environmentally safe mining (Testimony of Blankenship) A former physical and health education director is concerned about the fact that there has not been sufficient data collected on the effect of radioactive materials in runoff and waste. She believes there should be more research in these areas and asked that the public be protected from such hazards (Testimony of Mary Kay Greer). The Manasota-88 project for environmental qualities of 1968 and 1988 believes that issuance of the permit should be withheld until health implications can be determined concerning potential hazards to the Myakka and Manatee Rivers' watersheds (Exhibit 7). A former member of the Manatee County Planning Commission that approved the Beker application prior to action by the County Commission of Manatee County is in favor of the proposed project because Beker's plan to impound water will augment the water facilities of the county (Testimony of Reasoner). The City of Bradenton believes that since it is being required to meet advanced water treatment standards of discharge for sanitary sewage, Beker Phosphate Corporation should be required to meet similar standards (Testimony of Mayor A.K. Leach). A member of the Myakka City Civic Association who is an adjacent land owner to Beker Phosphate Corporation feels that the project is necessary in order to produce jobs for individuals in that area of the county (Testimony of Mizell). The U.S. Fish and Wildlife Service is concerned that proposed construction of two dams by the applicant will destroy approximately (4) acres of mangrove areas, three acres of pasture land and about 185 acres of bottom land or hardwood habitat. It recommends an alternative method of backup levies constructed around the primary settling bases on the applicant's land to contain any spills and prevent destruction of the streams and associated wetlands (Testimony of Johnston) The Conservation Council of Manatee County believes that Beker's unique mining and reclamation plan will help the farming industry and also create necessary water reserviors and recreation areas, and therefore endorses its proposal to mine in Manatee County (Testimony of Kent, Exhibit 14). Petitions were submitted at the hearing from approximately 3,000 individuals living in Manatee and Sarasota Counties opposing the issuance of the permit because they believe that phosphate mining is dangerous to the quality and supply of the water and endangers the health of the people (Composite Exhibit 9, Testimony of Humphrey).
The Issue The issues to be resolved in this proceeding concern whether the Petitioner has standing to bring this action and, therefore, whether the Intervenor has standing; whether the applicant has provided reasonable assurances of its entitlement to a construction permit for the facility; whether the applicant is precluded from availing itself of a separate biohazardous waste storage general permit through notification to the Department; whether the Petitioner is entitled to challenge the notice requirements of the general permit; and whether the facility to be permitted should be characterized as a biological waste incineration facility or a biohazardous waste treatment facility.
Findings Of Fact The Petitioner, Hamilton County Board of County Commissioners ("County"), is the governing body of Hamilton County, a political subdivision of the State of Florida. The operation of the political subdivision of Hamilton County is conducted by and through its duly-elected Board of County Commissioners. The County conducts a variety of official functions, including but not limited to, the levy and collection of taxes, construction and maintenance of county-owned buildings, roads, bridges and other facilities, the funding and maintenance of county recreational parks and related facilities, and the funding and operation of county health and welfare programs, as well as the regulation and disposal of solid waste and sewage. TSI is a Florida corporation organized to specialize in the construction and operation of incineration facilities, including biohazardous waste incineration facilities. The project sub judice is the first incinerator facility proposed for construction by TSI. The corporation and its directors, officers or operational personnel have not participated in the construction or operation of any type of incinerator facility in the past. DER is an agency of state government charged with the responsibility of regulating the quantity and quality of emissions from facilities such as the incinerators involved in the case at bar, and with reviewing applications for permits for the construction and operation of air pollution source facilities, including incinerators, as well as biohazardous waste disposal and treatment facilities and solid waste resource recovery and management facilities. Its reviewing responsibility is performed by weighing such permit applications against the yardsticks set forth in Chapter 403, Florida Statutues, and Rule Chapters 17-2, 17-4, 17-6, 17-701 and 17-712, F.A.C., which it employs to determine, among other parameters, whether a particular air pollution source facility can be reasonably assured to comport with the standards embodied in those rule chapters. The Intervenor, City of Jasper ("Jasper"), is a municipality located within Hamilton County, Florida. The Jasper Industrial Park is the site of the proposed biohazardous waste incinceration facility. That site is within the city limits of Jasper. Description of Facility and Process Incineration is the most commonly used procedure for treating medical waste. The combustion of waste is especially appropriate for hospital "redbag" waste, also known as medical waste. The combustion of medical waste destroys pathogens infectious materials and spores. TSI proposes to burn medical waste in two Basic Model 3500 biohazardous waste incinerators. The incinerators will be enclosed within a large building at the Jasper Industrial Park in Jasper, Florida. Each has a charging capacity of 35 tons per 24-hour day. The proper incineration of medical waste requires a residence time of one second in a secondary chamber, having a temperature of at least 1,800 degrees Fahrenheit. These time and temperature requirements will be achieved by the proposed Basic incinerator. The incinerator's loading door will not open until the secondary chamber temperature reaches 1,800 degrees Fahrenheit. Unlike other systems, the patented Basic incinerator system has three combustion zones in the incinerator, the main chamber, the secondary chamber, and the tertiary chamber. By means of these three stages, the Basic incinerator minimizes emissions of hydrocarbons, CO and nitrogen oxide. It is characterized by a "ram feeder" which allows the waste material to enter the incinerator through an air lock so as not to disturb control of the air within the furnace. It also has a "mechanical pulse hearth" which moves and tosses the burning material while moving it through the incinerator, shaking it up, much like logs in a fireplace. It thus mixes the waste material in the air for more complete combustion. Finally, a backhoe-type device digs the ashes out of the ash pit for disposal after combustion. The third stage of the Basic incinerator changes vapors coming from the main chamber to superheated gas. The "thermal exciters" in the third stage increase turbulence and mixing in this upper zone. With the addition of air in this third stage of burning, the gas burns like natural gas, thereby completely destroying the products of incomplete combustion from the previous stages. The gas will have a residence time of at least one second in the last combustion chamber, at no less than 1,800 degrees Fahrenheit, as required by Rule 17- 2.600(1)(d)4.A., F.A.C. The Basic incinerator is designed with an air lock door which prevents it from opening until the chamber temperature reaches the required 1,800 degrees Fahrenheit. This insures more complete combustion of waste and insures that the ignition of waste does not commence until the last combustion chamber temperature requirement of Rule 17-2.600(1)(d)4.D., F.A.C., is attained. After the tertiary stage, the gases resulting from combustion go to a heat recovery boiler system incorporating a heat exchanger involving water- filled tubes. The superheated gas flows past these heat exchanger tubes which reduce the gas temperature to approximately 250 degrees Fahrenheit. This serves to start condensing the HCL acid gas so that it will be amenable to reduction and conversion by the injection of finely-powdered lime on the way to the "baghouse" scrubber device. Additionally, at this stage, a portion of the superheated gases are recirculated to the combustion chamber for further exposure to combustion temperatures in order to achieve optimum burnout of all combustible materials. When the superheated gases reach the boiler-heat recovery, steam- generating device, they are at approximately 1,800 degrees Fahrenheit. In part, they consist of metallurgical fumes containing salts, oxides, heavy metals, leads and zincs. In order to prevent these salts from clogging the boiler, the cooling device reduces their temperature so that the oxides and metals form powders. Then if any of the resultant powder adheres to the boiler tubes, conventional coal-blowing equipment blows the resulting powders on through the boiler to the emission control device or "baghouse". This, in turn, maintains the temperature reduction efficiency of the boiler heat exchanger. Because of the various combustion stages or chambers incorporated in the incinerator, as well as the heat exchanger and gas recirculation feature, the Basic incinerator prevents burning particulate particles from entering the baghouse and burning holes in the Gortex filter bags. This, of course, insures optimum emission control efficiency. After the combustion gases exit the heat exchanger-boiler device, their temperature has been reduced to approximately 250 degrees Fahrenheit. Lime is injected at this point, which reacts with the HCL acid gas and neutralizes it in part; the reaction occurring as the gas flows toward the baghouse, with the reaction being completed on the surface of the Gortex bags of the baghouse, as the lime collects thereon. The County does not contest that the Basic Model 3500 incinerator, as proposed, will perform in a manner that will satisfy most of the criteria set forth in Rule 17-2.600(1)(d), F.A.C. It will achieve approximately 95% burnout in the combustion chambers. Mr. Cross, the County's expert witness, was concerned that DER had no criteria for a standard of "burnout" of the bottom ash. In fact, DER interprets the term "complete combustion" (in the above Rule), as requiring ash burnout of approximately 95%. The Basic incinerator will achieve 95% burnout. The high rate of burnout is achieved both by the multiple combustion chambers and the use of the moving pulse hearth which constantly shakes or stirs the burning material, ending with chains suspended at the end of the pulse hearth to impede bulky waste materials from exiting the combustion chamber before they are completely combusted. Odor is controlled, in accordance with Rule 17- 2.600(1)(a)2., F.A.C., by using air for combustion purposes which is drawn by blowers from the storage area of the untreated waste. The combustion blowers pull air from the waste storage area into the incineration system. The best means of odor control is by burning, which this incinerator will achieve. The County agrees that CO emissions from the incinerators will not exceed 100 parts per million by volume, dry basis, corrected to 7% 02, on an hourly average basis. Thus, CO will be within acceptable regulatory limits and is not at issue in this proceeding. Pursuant to stipulation, the only emissions at issue with regard to the proposed facility and permit are visible emissions, particulate matter and hydrochloric acid (HCL). Particulate matter consists of finely divided solids or liquid, and the hydrochloric acid is formed when chlorinated plastics are burned. Emissions are reduced in two ways. First, emissions from the stack of the incinerator will be diluted by ambient air which dilution increases as the stack height above ground increases. Airborne emissions are also reduced by directing combustion gases through pollution control equipment before they exit the stack. The pollution control equipment proposed for the incinerators at issue is an acid gas, dry lime scrubber baghouse, with dry lime injection. The incinerator facility cannot meet particulate and hydrochloric acid standards without the addition of a pollution control device, such as a dry lime scrubber baghouse. The baghouse is the best available technology for controlling particulates and hydrochloric acid, as well as controlling metals emissions. The baghouse works much like a vacuum cleaner with a vacuum cleaner bag to trap particulate matter. Baghouses have been in use since 1970, and the technology has been scientifically demonstrated and accepted. The proposed baghouse would consist of a multiple number of bags in excess of ten feet long. They are made of fiberglass, coated with Gortex, a permeable membrane material. They have an air to cloth ratio of 3 to 1. The Gortex bags are capable of trapping 99.5% of particles in the range of 1/10th of a micron in diameter. They are, thus, capable of trapping cigarette smoke, for instance, and are resistant to acids, certain alkalines, and temperatures up to 500 degrees Fahrenheit. The bags are wrapped around a wire cage and attached to a steel plate, anchoring them to the flues, which conduct the gases to them. All of the flue gases enter the baghouse and go through the bags and then exhaust to the atmosphere through the stack. The bags, thus, trap most particulate matter and metals. Additionally, lime will be injected into the flue gas stream for acid control before the flue gases reach the bags. The lime dust, a base, reacts with HCL, an acid, to produce calcium salts, which are PH neutral. The dry lime will be conducted from a silo or other means of storage in the form of fine dust or talc which enters a metering hopper so that the amount of lime injected into the system can be controlled. The lime is injected immediately after the gases are condensed and cooled to a 250 degree Fahrenheit level. This causes optimum reaction of the acid gases with the lime which then travel together to the bags. The Gortex bags are coated by the lime dust which further enhances the HCL removal reaction. Because of the recirculation of the superheated gases and the cooling of them through the heat exchanger device, it is very unlikely that any sparks or embers from the incinerator chambers will land on the bags to burn holes in them and, thus, reduce their efficiency. This is an inherent advantage of the design of the Basic incinerator when used with the Gortex' baghouse scrubber. There is a biohazardous waste incineration facility in operation at Stroud, Oklahoma. It uses a Basic incinerator also employing an acid gas, dry lime scrubber baghouse, in essence like the one proposed here. That incinerator has been tested for visible emissions, particulate matter emissions, and HCL emissions. The tests occurred while the incinerator was actually combusting twice the amount of medical waste proposed for the proposed incineratcrs. The visible emissions test at that facility resulted in an opacity of less than 5% (visible emissions). The PM test resulted in 0.014 grains per dry standard cubic foot. HCL emissions from the incinerator were tested at 43.6ppm (parts per million). The Stroud system thus achieved a 97.2% removal of HCL. A medical waste incineration facility is located at Fairfax, Virginia, which uses a baghouse and lime injection system. The Fairfax facility test results also establish that a baghouse lime injection system reduced particulate matter and HCL emissions to below the Florida standards. Experts testifying on behalf of both the applicant and the County agree that the design characteristics and pollution control capabilities of various lime injection systems and baghouses differ markedly. Certain baghouse designs would not be appropriate for the pollution control application at issue. The County's expert noted that the method of lime injection is a critical component of overall HCL control. Certain baghouses incorporate intermittent lime injection systems which are effective for protecting the individual baghouse components, but inappropriate for HCL removal purposes. The applicant's expert, Mr. Basic, also recognized the importance of the type of lime injection system involved. Various baghouse manufacturers inject lime at differing points within the system; and certain injection applications are, in his opinion, inappropriate for effective HCL control. Temperature is a critical factor in the effectiveness of the lime injection procedure in neutralizing the acid gases (HCL). The method proposed by the applicant of cooling the gases to approximately the range of 250 degrees Fahrenheit before injection of the lime has been shown to be effective in neutralizing the HCL gases at issue, when coupled with the Gortex-laminated, fiberglass bags upon which further neutralization will occur as the dry lime powder is deposited thereon and the gas passed through it. The baghouse cleaning system is also a component of major importance. Baghouse cleaning involves the removal of calcium chloride particulate buildup from the surface of the filter bags. They eventually become clogged with the precipitate, reducing the systems effectiveness unless they are periodically cleaned. Baghouses can be cleaned while the incineration system is shut down which is known as "off-line cleaning". They can also be cleaned during operation by "on-line cleaning". "Pulse-jet" cleaning involves taking a portion of the bags off line with a damper system bypassing the flue gases to other bags which remain in operation. The bags taken off line are then injected with a rapid pulse or pulses of compressed air, thereby removing the calcium chloride cake from the bags. The County's expert opined that pulse-jet cleaning is less effective than off-line cleaning and that it also requires a dedicated air compressor, as air from within the plant may contain moisture, oil or other contaminants, which are inappropriate for injection into the baghouse since they may permanently clog or otherwise harm the bag material. The applicant's expert, Mr. Basic, expressed like concerns regarding the baghouse cleaning system. He testified at length about the characteristics and appropriateness of on-line versus off-line cleaning. He established that off-line cleaning, also knowh as "reverse air" or "reverse jet" cleaning, is the most effective under the situation prevailing in this project and, in essence, agreed with the County's expert on this subject. Reverse air cleaning involves both the incinerator and the air pollution control system being shut down, with air from the blower being blown in reverse through the bags to remove the calcium carbonate residue. Mr. Basic's testimony establishes that a reverse air, off- line cleaning process can maintain the effectiveness of the Gortex- fiberglass filter bags and, thus, assure that emission and ambient air standards are continuously met by the facility. Stack Emissions Modeling of the stack emission results predicted at the facility with the originally-proposed 40-foot stack height was performed by Mr. David Buff, the applicant's expert witness in this regard. The model he employed demonstrated compliance with all ambient air quality standards set forth in Chapter 17-2, F.A.C. There is no ambient air quality standard in the rules at the present time for HCL, however. DER does have a policy, established without dispute in this record, that an acceptable ambient level of HCL would be 150 micrograms per cubic meter for a three-minute value and 7 micrograms per cubic meter on an annual average. Shortly prior to hearing, a "re-modeling" of the stack and resultant emissions was done, postulating a stack at 98 feet high. Five years of meteorological data from the Valdosta, Georgia, weather station were used to include such factors as prevailing winds, etc., which modeling ultimately demonstrated a three-minute maximum HCL concentration of 16.4 micrograms per cubic meter. This resulted in a maximum HCL concentration at ground level of a factor of 10 below the 150 micrograms per cubic meter level, which is acceptable under DER policy. The average annual impact of HCL concentrations would be 0.2 micrograms per cubic meter, well below the acceptable level of 7 micrograms per cubic meter annual average. Mr. Buff's model also predicted a maximum annual average impact at any location in the vicinity of the proposed incinerator of HCL at .16 micrograms per cubic meter. This maximum value is a factor of more than 40 below the administrative level of 7 micrograms per cubic meter on an annualized basis. A spatial distribution of the annual average hydrochloride concentrations in the vicinity of the incinerator demonstrates an annual average concentration declining to 0.09 micrograms per cubic meter in the direction of the City of Jasper. The 98-foot stack proposed by TSI thus meets all ambient air requirements. Although the stack height was changed from the 40 feet shown in the application to 98 feet, all other design elements of it, such as stack diameter, stack temperature, and gas flow rate, remain unchanged. The modeling of the 98-foot stack included all of the design criteria found in the application. There is, in essence, no dispute regarding the efficacy of the modeling performed by Mr. Buff. All modeling and modeling results were not controverted. In addition to the main stack, there is an emergency relief stack, also known as a "dump stack". The dump stack does not have pollution control equipment. It is opened when the system is first started up in order to purge the system. No waste is burned at that time. The stack is also opened after a shutdown during a cooldown period after all waste has been removed from the furnace. The likelihood that the relief stack will operate outside of a startup and cooldown period is very slight. The facility will have an electrical generator backup emergency power source in case of power failure. The primary reason for the stack's opening, power loss, is thus eliminated by the system as proposed. There is a relief valve in the steam line so that if steam pressure in the boiler exceeds operating pressure, the system can be relieved through the relief valve with the only loss being steam which would have to be replenished with soft water. Such a malfunction would not result in the emergency stack opening, however. The only other circumstance under which the emergency stack would open, and vent gases to the atmosphere without emission control, would be a malfunction of the blower or induced draft fan system which pulls the gases out of the main stack. This could be caused by failure of the drive belts or a burnout of a motor. With proper maintenance, the belts will not fail and the motors will function for years without replacement. In an emergency situation, however, if a shutdown does occur, the frequency of the pulse hearth can be increased to push the waste stream into the quench pit in approximately 20 minutes, thus, eliminating emission of pollutants through the stack. The County's expert, Mr. Cross, also agreed that most of the causes of the opening of the emergency dump stack have been eliminated by the proposed Basic design. In any event, even in an emergency situation where the dump stack must open, the inherent design capabilities of the incinerator, related to operating temperature, residence time and the multiple combustion chambers, result in only one part per million CO, as well as very low nitrogen oxide and hydrocarbon levels being emitted from the facility even with no other pollution emission control provisions. In the event the emergency stack opens, the highest HCL emissions occur immediately, but then quickly drop to acceptable levels. This is so because combustion of materials immediately in the furnace would be finished, but no other charging of the furnace would occur until the malfunction is alleviated. Rule 17-2.250, F.A.C., allows, in any case, with an emergency opening of dump stack, the excession of permit limits for up to two hours. The results of modeling the operation of the dump stack at a 40-foot height and at 30 pounds per hour of HCL emissions shows that the 7,500 threshold limit value ("TLV"), which the Occupational Safety and Health Administration ("OSHA") sets to protect worker safety, will not be exceeded anywhere off the plant property, which boundaries lie 50 meters or more from the stack location. The HCL administrative level set by DER (by policy) of 150 micrograms per cubic meter will be exceeded in an area out to approximately 400 meters from the stack. Beyond 400 meters, the level is less than that and drops off rapidly thereafter so that at 800 meters, under the model prediction, the level of HCL concentration would be only 57 micrograms per cubic meter and at 2,000 meters, 37 micrograms per cubic meter. The county prison site, the Hamilton County landfill, recreation park, middle school, county road camp, senior citizens center, other schools and a nursing home, of which concern was expressed about proximity to incinerator emissions, are all 900 meters or more from the site of the incinerator and the location of the stack. It has thus been established that ambient HCL concentrations will not reach the prohibited level of 150 micrograms per cubic meter for the three-minute average at any of these locations. The permit applied for is a "minor source construction permit". Such a permit allows the applicant to construct the source, having an initial startup and performance compliance testing period to demonstrate that the facility can meet emission standards provided for in the permit and related rules. After demonstrating compliance, the applicant can then seek an operating permit. The test methods required as conditions by DER's proposed grant of the permit and the "draft permit" are standard ones sanctioned by the U.S. EPA. They are reliable and acceptable and have undergone independent testing and development and are used by all states. Thus, the combustion chamber exit temperature must be monitored for the purpose of determining if the unit complies with the 1,800 degree Fahrenheit rule, the criteria for complete combustion. Oxygen must also be monitored for the purpose of determining if the incinerator is operating properly and achieving good combustion which is essential to control of hydrocarbons, nitrogen oxides, CO and other pollutants. When oxygen falls below certain levels, the computerized micro- processor monitoring system shuts down the loader to prevent charging of the furnace until combustion standards are again reached to prevent insufficient combustion due to low oxygen and excession of pollutant limits. In order to insure that the CO limit of 100 parts per million is not exceeded, a continuous CO monitoring capability will be installed within the incinerator. The lower the CO, the better the combustion efficiency. Although the rules require a 100 parts per million limit, CO test results at the Stroud facility, which is essentially identical to the one proposed, averaged 1.1 parts per million. Test results at the Stroud facility also demonstrated that the dry lime scrubbers installed there accomplish high HCL and particulate removal. The Stroud facility meets all Florida rule standards. Mr. Cross acknowledged that the test results on that facility demonstrate that dry lime scrubbers on medical waste incinerators "will do the job". Design details of the 98-foot stack and the lime injection baghouse scrubber facility were not included in their entirety in the application and the evidence adduced. Design details of the 98-foot stack, however, were provided in the application on page 6 as to the 40-foot stack. The changing of the stack height to 98 feet does not change the remaining design details, and they are still valid and have been proven so. Although no design or plans for the lime injection baghouse proposed have been adduced, the testimony of Mr. Basic establishes that such a facility will meet all pertinent emission standards prevailing in the Florida rules and policies, as such a facility did in the Stroud tests. Mr. Basic's testimony was unrefuted and establishes that the dry lime injection baghouse scrubber facility, such as he proposes and about which he is knowledgeable, based upon his manufacture, installation and operation of other incineration facilities, will reasonably assure that all pertinent disputed emission standards will be met (for particulate matter, opacity and HCL). Mr. Basic, as equipment vendor for the project, has responsibility for the entire incineration facility. He will oversee construction, installation and testing of the incinerators and emission control equipment (baghouse and stacks). He has guaranteed that all Florida emission standards will be met as the manufacturer and vendor for the project. A grant of the permit at issue should be conditioned upon Mr. Basic performing, as testified at the hearing and as agreed to by the applicant, as overseer for the construction, installation and testing of the proposed facility. Specific Condition No. 14 in DER's notice of intent to grant the permit requires the applicant to test the resultant ash to see if it is hazardous. Ash from the proposed facility must be tested in accordance with 40CFR 262.11, which requires testing and characterization of the waste. Ash from the proposed facility will be tested; and if it tests as hazardous, it will be handled as hazardous waste by sending it to an approved hazardous waste landfill or treatment facility. In any event, it has been stipulated by the applicant that the ash will not be deposited in a Hamilton County landfill; and the permit should be so conditioned. Most ash coming from infectious waste incineration is non-toxic. Controlled air incineration produces a sterile ash, which is a non-combustible residue, and may be disposed of in an ordinary landfill. Ash tested at the Stroud facility, after burning medical waste of the type to be incinerated in the instant facility, tested as non-hazardous. The ash will be removed from the facility in closed containers. Storage of Biohazardous and Biomedical Wastes DER regulates biohazardous waste incineration under the air permitting program, requiring an air permit, as sought in the instant case. DER does not require a separate solid waste treatment and sewage permit. Biomedical waste is regarded as a special waste which requires an element of care beyond solid waste, but does not require the extraordinary care required of hazardous waste. Sections 17-712.420 and 17-712.800, F.A.C., deal with the permitting of biohazardous waste storage. There are two ways in which an applicant can notify DER of its intent to use a general permit for the storage of biohazardous waste: It can apply for a general permit by notifying DER on a specific form of its intent to use a general permit for the storage of the waste; or It can include the information as part of an air permit application. With either option, there is no difference in the way DER processes the two types of notification. DER reviews the information submitted to make sure that it indicates that the facility will meet the requirements of Rule 17-712.420, F.A.C. The DER district waste program administrator, Mr. Mike Fitzsimmons, established in his testimony that the applicant has met the qualifications for the general permit for biohazardous waste storage. Five areas have been designated for storage of the biomedical waste to be incinerated at the TSI facility. It is anticipated that most of these areas will normally be empty. The storage areas are available, however, in case one of the incinerators is inoperative for any reason. There are contingency plans for re-routing the waste in the event one or both incinerators are inoperative for a significant period of time. Area A is the primary area of the facility where boxes are loaded onto a conveyor system and continuously fed into the furnaces. Area B is considered a secondary storage area where palletized boxes can be stored pending their placement onto the conveyor system for charging into the incinerators. The secondary area here can also be used for backup storage. Areas C and D are truck unloading docks,. The trucks, themselves, also can be used for storage capacity. Area E on Exhibit 7, the permit drawings, shows an outdoor storage area which will hold a number of trucks which transport the biohazardous waste. All of the trucks bringing waste into the facility will remain locked until brought to the unloading dock for unloading and incineration of their contents. The loading docks for the trucks located at the back of the facility are designed with drainage to prevent storm water runoff. Both the indoor and outdoor storage areas will be concrete. The concrete joints will be grouted and sealed, and the concrete will have an impermeable sealant placed on it. To maintain a sanitary condition, the area will be swept daily; and any spill area will be disinfected. The indoor areas will be disinfected weekly regardless of spills. Access to the proposed facility will be restricted to prevent entry of unauthorized persons. The outer perimeter will be enclosed with an 8-foot cyclone fence. It will be monitored with closed-circuit television. The building itself will only be accessible by authorized persons. The fence and all of the entrances will be marked with the international biohazardous symbol with the words "biohazardous wastes or infectious wastes". The facility will be operated so as to prevent vermin, insects or objectionable odors offsite. All materials will be packaged according to Rule 17-712.400(3), F.A.C. Refrigeration is not contemplated because EPA guidelines on management of infectious waste do not recommend refrigeration. Instead, storage times will be kept as short as possible prior to incineration. There will be minimal handling of boxes at the facility. Semi-trailers will be unloaded by means of an extendo conveyor system which will convey the boxes directly to the incinerators. If a box is dropped, breaks or a spill occurs, the area will be disinfected immediately. All floor drains, which will be installed both indoors and outdoors, will have a slight slope in the direction of the drain so that the floors can be scrubbed and hosed down and disinfected with all liquid material being flushed down those drains. Liquid waste created by the disinfection process can be safely disposed of thereafter in the city sanitary sewer system. The storm water management system on the site and the drainage sewage system are entirely separate, however. Employees will be required to wear either rubber or plastic gloves and white disposable clothing. All biohazardous waste generators (hospitals, etc.) and transport companies will be required to put the waste in "red bags", strong plastic bags. The medical waste will be required to be sealed in strong plastic bags, which are then placed by the generator of the waste in sealed cardboard boxes having a 275-pound bursting strength. All boxes must be marked with the name and address of the generator of the waste (hospital, etc.). The transporter of the waste, typically a trucking company, will be required to keep the trailers transporting the waste locked and the boxes intact and unopened. The applicant, as a condition of the permit, will not accept delivery of any waste shipments not so packaged and maintained. In fact, in addition to the rules governing the packaging and transport of biomedical waste contained at 17- 712.400, 17-712.410, F.A.C., TSI will require, by written contract, generators and transporters of the biomedical waste to insure delivery of waste properly packaged in accordance with Florida law regardless of which State the waste is generated and transported from. Additionally, the applicant will maintain records of waste origins and shipments in accordance with Rule 17-712.420(7), F.A.C., in its computerized record system. A detailed contingency plan will be prepared for the proposed facility by Lloyd H. Stebbins, P.E., an expert in environmental incident planning. The contingency plan will include more detail than is required by the biohazardous waste rules. The plan will address how medical waste is handled in order to insure public safety and the safety of employees as it is transported to and enters the plant and how ash will be safely handled when it exits the plant. Mr. Stebbins will also prepare an operation plan which will include personnel training in disinfection procedures and a description of those procedures for submittal to DER as a condition of a grant of this permit. That operation plan will contain procedures for all three types of disinfection methods authorized by Rule 17-712, F.A.C. This will enable the applicant to have the flexibility to use all three procedures, hot water, sodium hypochlorite, iodine or an EPA approved germicide. Mr. Stebbins will direct and provide training to insure that personnel comply with the regulations concerning disinfection and proper application of disinfectants. As an additional safety factor, the facility is designed to operate efficiently at approximately 85% of its actual capacity in order to allow for "down time" and maintenance. Standing TSI has challenged the County's standing to participate in this proceeding, asserting that Hamilton County, through its duly-elected Board of County Commissioners, does not possess a substantial interest in the outcome of this proceeding different from that of the public generally. It contends that the concerns various members of the general public might have concerning location and installation of the incinerator facility are the only concerns that the County has in participating in this proceeding; and, therefore, that the County has no substantial interest of its own justifying its standing to be a party to this proceeding. The record, however, reveals a strong citizen opposition in the County and City of Jasper to the applicant's proposed project. During the public comment portion of these proceedings, it became obvious that the citizens of Hamilton County have a variety of health and safety concerns which have engendered wide spread opposition to the applicant's project. Principal concerns are the matters of transportation and potential spillage of infectious hospital- generated medical wastes which the incinerator will be treating. Additionally, a strong concern has been expressed by various citizens of Hamilton County and the City of Jasper, concerning potential HCL emissions and their potential negative health effects on residents of the city and county, particularly those who utilize the many publicly-owned facilities located in proximity to the project site. These facilities include a middle school, a senior citizen center, a county road camp or prison, the county landfill, county equipment, a bridge and other buildings, as well as the fact that the material to be incinerated will be transported on trucks through a residential area. Additionally, the Hamilton County Correctional Institution is immediately adjacent to the proposed project site and employs several dozen county residents. Concerns were also expressed about increased traffic flow resulting from trucks bringing waste through the county and city to the proposed incinerator site, as well as the health and safety of the citizens who will be employed at the proposed facility itself, and the lack of sufficient emergency equipment and facilities within Hamilton County. Many citizens expressed their opposition to the proposed facility at the public comment portion of the hearings, through petitions submitted to their city council and the board of county commissioners and at public meetings conducted by those two governmental bodies. Thus, it can be inferred that there is a concensus of opposition by citizens of the city and the county which has been expressed to their respective governing commissions, who are the Petitioner and Intervenor in this proceeding. There is no question that the proposed project has the potential to cause some pollution or degradation of air and water in Hamilton County and the City of Jasper. Section 125.01(1), Florida Statutes, delegates broad powers and duties to county governments. Those powers and duties are enumerated in the Conclusions of Law below and include such authority as to establish and administer programs of air pollution control; to provide for and regulate waste and sewage disposal; to operate solid waste disposal facilities pursuant to Section 403.706(1), Florida Statutes; to establish, coordinate and enforce zoning and such business regulations as are necessary for public protection; to perform other acts not inconsistent with the law which are in the common interest of the people of the county, and to exercise all powers and privileges not specifically prohibited by law.
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 aguments of the parties, it is therefore, RECOMMENDED that DER enter a final order approving TSI's applications for permits for the subject two biological waste incineration facilities in accordance with the conditions specified in the notice of intent to grant the permit and enumerated in this Recommended Order.
