Findings Of Fact Petitioner's present solid waste-disposal system consists of the operation of six sanitary landfill sites. These sites are being operated in accordance with temporary permits issued by the Respondent. Four of the sites are not adequate sanitary landfill sites. Two of the sites, which are known as the "Sims Farm" and "Ephesus" sites can be developed into acceptable landfill sites. Petitioner has not developed any comprehensive plan designed to comply with the Florida Resource Recovery and Management Act, and the rules of the Respondent respecting solid waste disposal systems. When its present temporary permits expire the Petitioner intends basically to continue operating the Sims Farm and Ephesus landfill sites, and to' locate at least two other acceptable sanitary landfill sites. Petitioner intends to comply with all of the Respondent's regulations, but it contends that it cannot comply with the regulation which requires that the landfills be covered every working day. Petitioner proposes to cover the landfills twice weekly rather than daily. Lafayette County is a large county in terms of area, but is very small in population, having less than 3,500 residents. Residents of the county are engaged primarily in agriculture. The county does not have a broad tax base. Estimated revenues for the 1977 fiscal year are $113,340. Thirty thousand dollars has been designated from the county's budget to operate a solid waste disposal system. The clerk of the County Commission is in charge of the county's present solid waste disposal system. The county does not have a full time employee designated to operate the system. The clerk of the County Commission has many duties other than operating the solid waste disposal system. Residents of the county are satisfied with the present system. Prior to the opening of the present sanitary landfill sites there was considerable dumping on private property, on highway right-of-ways, or in the river slough. The amount of waste deposited in the county's present landfills is very small in relation to counties with a higher or more concentrated population. There is very little industrial or commercial waste, and a smaller percentage of putrescible materials than would be found in more urban counties. Although there is a county ordinance prohibiting it, dead animals are occasionally deposited in the landfill sites and burning of trash does occur. Chemical agricultural waste is also deposited in the landfills. Lafayette County has utilized temporary permits to operate its present landfill sites. The permits require the submission of periodic reports. The county has not submitted these reports as required by the permits. Counties surrounding Lafayette County have had varying experiences in reaching full compliance with the Florida Resource Recovery and Management Act, and the rules of the Respondent dealing with solid waste disposal systems. In Taylor County, a county with a population of approximately 14,500, approximately $120,000 was invested in equipment. Daily cover of sanitary landfills, including the dumping of green boxes utilized in Taylor County cost $6,512.42 in January, 1976, and $7,159.85 in January, 1977. Compliance with the statutes and regulations necessitated an increase in the county's tax rate. Compliance is being achieved in Gilchrist County, a small agricultural county at very low cost utilizing a single sanitary landfill site system. Compliance has been achieved in Dixie County, a small agricultural county through use of a green box system. Very little research has been performed by Lafayette County to determine how compliance could be achieved most inexpensively. Daily cover of sanitary landfill sites is desirable. Daily cover is the most effective means of preventing open burning in landfill sites, leachate of solid waste, flies and rodents. Daily cover does not totally alleviate these conditions, but it is the most effective means of combating them. Daily cover is much more necessary in areas where there are large amounts of solid wastes than it is in areas with small amounts. Daily cover is also more necessary in areas where there is a large proportion of putrescible versus non-putrescible materials than it is in areas with a smaller percentage. In order to comply with the Respondent's regulations when its present temporary permits expire, the Petitioner will need to purchase a tractor or bulldozer in order to provide a cover at the landfill sites. If daily cover is required, the county will need to hire a full-time individual to perform the cover. If twice weekly cover is permitted the county will be able to operate its system without the necessity of employing an additional person. Twice weekly cover would reduce the operating costs of the county's system by reducing fuel and maintenance costs of vehicles. In view of the fact that no detailed examination has been made of the cost of full compliance, it is not possible to determine from the facts presented whether it is practicable for the Petitioner to comply with the regulations, or whether the expense or cost of measures which the Petitioner must take in order to comply are so great that they should be spread over a considerable period of time. The most that can be determined is that daily cover would be more expensive than twice weekly cover, and that twice weekly cover would not have any profoundly negative environmental effects in Lafayette County.

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.

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.
Recommendation It is RECOMMENDED that the Department of Environmental Protection enter a final order granting the Construction Permit and Operation Permit, but only if the Operation Permit is modified by the addition of the five items identified in paragraphs 172, 174, 175, 181, and 187.

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. RECOMMENDED this 4th day of January, 1984, in Tallahassee, Florida. MARVIN E.

OGC Case No. 83-0363 DOAH Case No. 83-2155 WASTE AIDES SYSTEMS, INC., and STATE OF FLORIDA DEPARTMENT OF ENVIRONMENTAL REGULATION, Respondents. /
The Issue Whether the costs incurred by the Department of Environmental Protection, Bureau of Emergency Response (Department) in connection with its response to Incident Number 95-SE-0248 may be recovered from Petitioners pursuant to Chapters 376 and 403, Florida Statutes.
Findings Of Fact The Department is a state regulatory agency charged with the responsibility of administering and enforcing the provisions of Chapters 376 and 403, Florida Statutes. Spill Response, Inc. (Spill Response) is a corporation which was formed in approximately 1986 or 1987, and is presently inactive and without any assets. At all times material to the instant case, George Gordon has been the sole owner, president and director of Spill Response, and, as such, has directed the operations of the corporation. Spill Response was previously in the oil spill response business, as its name suggests. At such time, it had an office in Port Everglades and stored its equipment on fenced and gated property located at 3211 Southwest 50th Avenue, Davie, Florida, on which approximately a dozen large aboveground petroleum storage tanks (surrounded by concrete containment areas) also were situated. At all times material to the instant case, the property located at 3211 Southwest 50th Avenue, Davie, Florida (FPR site) has been owned by Florida Petroleum Reprocessors, Inc. (FPR), an inactive corporation that previously was in the waste oil recovery business. The FPR site, which is presently FPR's only asset, is the subject of a pending foreclosure action initiated by Charles Green, who, at all times material to the instant case, has held a first mortgage on the property. At all times material to the instant case, George Gordon has been the president and director of FPR, and, as such, has directed the operations of the corporation. In the latter part of 1994, the storage tanks on the FPR site were no longer in commercial use. At that time, Gordon, on behalf of FPR, hired Fred Rice to clean and maintain the site in preparation for its closure. Rice was instructed to remove the petroleum residue and sludge from the tanks and from the containment areas. Rice engaged in these petroleum and sludge-removal activities on a part-time basis until the spring of 1995, when he stopped working on the project after not having received timely payment for work he had performed. Rice placed the petroleum residue and sludge that he had removed, as well the rags and other materials that he had used in the removal process, in 55-gallon drums. He filled approximately six or seven such drums. A number of other 55-gallon drums containing petroleum residue and sludge (that some person or persons other than Rice had filled) were already on the FPR site. Rice put the six or seven drums that he had filled on a truck that was parked on the site and had “Spill Response, Inc.” and “Florida Petroleum Reprocessors, Inc.” markings on its sides. The truck was owned by Spill Response and had been on the site for some time. It had no battery and was inoperable. Rice told Gordon that he had put the drums he had filled with petroleum residue and sludge on the Spill Response truck. The next time Gordon went the FPR site, in late May of 1995, he discovered that the locks on the gates had been changed and that there were vehicles and equipment on the property that did not belong there. Gordon telephoned the Davie Police Department to complain about the unauthorized use of the FPR site. A police officer was dispatched to the site to investigate. When the officer arrived on the scene, he encountered Gordon outside one of the gates. Although the gate was locked, Gordon and the officer gained access to the site by squeezing through an opening in the gate. Upon entering the site, they looked around. Based upon what they saw, they correctly "figured out" that Certified Crane and Rigging, Inc., d/b/a Certified Equipment Management Company (Certified) was storing its crane equipment and trucks on the site. At all times material to the instant case, Certified has been owned and operated by William "Skip" Walton. Walton is an acquaintance of the aforementioned Charles Green, the holder of the first mortgage on the FPR site. Certified's telephone number was painted on the equipment and vehicles it was storing on the FPR site. The police officer called the number and spoke with Walton. Following his telephone conversation with Walton, the officer informed Gordon that Walton had indicated, during the conversation, that he was leasing the FPR site from Green. Gordon advised the officer that he did not want to press criminal charges (for trespassing) against either Certified or Walton. Gordon subsequently telephoned Green. Green told Gordon that it was true that he had leased the FPR site to Walton. Green explained to Gordon that he "needed to earn some money from the property." (It had been some time since Green had received any mortgage payments from FPR or Gordon.) Gordon contacted his attorney to discuss with her what legal action, if any, he could take to regain possession of the FPR site and be compensated for the unauthorized use of the property. Gordon's attorney advised him that he "would have recourse if [he] wished to pursu[e] the matter in court," but that it might not be cost-effective for him to do so. Gordon took no action, "in court" or otherwise, to regain possession and control of the FPR site; nor did he take any action to retake possession and control of the Spill Response truck or the filled drums that were in the truck and elsewhere on the site. Furthermore, he made no effort to make sure that the drums and their contents were stored and disposed of properly, believing that the proper storage and disposal of these items were now the responsibility of the new occupant of the site. He did not return to the FPR site for over a year. On or about June 6, 1995, the Department was notified (after its regular business hours) that the Spill Response truck had been discovered abandoned on the side of the road a few blocks from the FPR site. The following day,1 Ann Meador, an Environmental Specialist III with the Department, went to the location where the truck had been abandoned and served as the Department's on- scene coordinator. The truck was in poor condition and still inoperable. It had been brought (not driven) to the location by someone other than Gordon. The truck contained 37 sealed 55-gallon drums, which were in poor condition (but not yet leaking) and had oil residue on the outside. It could not be reliably determined exactly what was in the drums without removing them from the truck and examining and analyzing their contents. Meador made arrangements for OHM Remediation Services Corporation (OHM), with whom the Department had a contract to perform such services on an emergency basis, to assist in the removal of the drums from the truck. OHM personnel (with "Level B" protective clothing and equipment) responded to the scene and removed all 37 drums from the Spill Response truck. After the drums were unsealed, their contents were examined and sampled to the extent possible2 (as were the contents of three additional drums which were filled with the "Level B" protective clothing and equipment that OHM personnel had used during the cleanup operation and then discarded). Each of the drums was assigned a number for identification purposes. To save time and money, samples from some of the drums were composited. The drums were then overpacked and taken to the Department’s hazardous waste storage facility in West Palm Beach, Florida. The Department paid OHM $7,046.93 from the Water Quality Assurance Trust Fund for the services OHM performed. In requesting OHM to perform these services and in paying OHM $7,046.93 for having done so, the Department acted reasonably and prudently. The amount it paid OHM was not excessive. The Department hired Laidlaw Environmental Services (Laidlaw) to analyze the samples that OHM had collected and to then properly dispose of the drums and their contents. Laidlaw's analysis revealed the following: drums numbered 1, 2, 3, 4, 5, 9, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 30, 34, 35, 36, 37, and 38 contained oily sludges, oil, oil mixed with water, or oily residues; drum numbered 6 contained benzene and had a flash point between 73 and 140 degrees Fahrenheit; drum numbered 29 contained benzene and lead and had a flash point of less than 73 degrees Fahrenheit; drums numbered 10 and 11 contained benzene and lead; drums numbered 7, 8, 31, 32, 33 and 39 contained benzene, lead, and cadmium. Laidlaw properly disposed of the drums based upon the results of its analysis. The Department paid Laidlaw $21,163.90 from the Water Quality Assurance Trust Fund for the services it performed. In requesting Laidlaw to perform these services and in paying Laidlaw $21,163.90 for having done so, the Department acted reasonably and prudently. The amount it paid Laidlaw was not excessive. The Department reasonably incurred other expenses (also paid from the Water Quality Assurance Trust Fund) totaling $129.82 in connection with its response to the report it had received concerning the abandonment of the Spill Response truck. The total amount the Department paid from the Water Quality Assurance Trust Fund to have the drums on the truck properly removed and disposed of was $28,340.65. It was not until Gordon received a letter from the Department advising him of the costs the Department had incurred and requesting that Spill Response and he reimburse the Department for these costs that Gordon became aware of the fact that the truck and the drums had been moved from the FPR site.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered by the Department finding that it is entitled to recover from Petitioners, pursuant to Chapters 376 and 403, Florida Statutes, the $28,340.65 in costs the Department reasonably incurred in connection with its response to Incident Number 95-SE-0248.

The Issue The issue presented is whether the application of Respondent Robbie's Safe Harbor Marine Enterprises, Inc., for a general permit to construct and operate a solid waste transfer station should be granted.
Findings Of Fact In April 1998 Respondent Robbie's Safe Harbor Marine Enterprises, Inc., filed an application with Respondent Department of Environmental Protection, seeking a general permit to construct and operate a solid waste transfer station at the end of Shrimp Road on Stock Island in Monroe County, Florida. The application was accompanied by the required supporting documentation, including a site plan and an engineering report. The site plan submitted with the application depicted access to the transfer station by using Shrimp Road. The access road was also designated as a private road. What the site plan and remainder of the application did not reveal is that Shrimp Road, the private road providing access from the public road system to the proposed solid waste transfer station, is not owned by Robbie's. Rather, the road is owned by the adjoining property owner, Petitioner Safe Harbor Enterprises, Inc. Robbie's is the holder of an easement allowing use of Shrimp Road. Robbie's published notice of its application for a general permit to construct and operate a solid waste transfer station. As a result of that notice, the adjoining property owner, Safe Harbor Enterprises, Inc., filed the petition initiating the instant proceeding, objecting to the issuance of a general permit to Robbie's. On February 2, 1998, prior to Robbie's filing its application for a general permit to construct and operate its solid waste transfer station, Robbie's entered into a Consent Order with the Department which resolved the Department's allegations that Robbie's had been operating a solid waste transfer facility without a permit.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a final order be entered denying Robbie's Safe Harbor Marine Enterprises, Inc.'s, application for a general permit to construct and operate a solid waste transfer station.

The Issue Is Respondent, Watson Construction Company, Inc. (Watson), entitled to a general permit allowing it to operate a construction and demolition debris facility in Newberry, Alachua County, Florida?
Findings Of Fact DEP, in accordance with Chapter 403, Florida Statutes, is responsible for enhancing the beauty and quality of the environment; conservation and recycling of natural resources; prevention of the spread of disease and creation of nuisances; protection of the public health, safety and welfare; and provision for a coordinated statewide solid waste management program. It accomplishes these tasks, in part, by regulatory oversight directed to entities who operate solid waste facilities in Florida. That oversight includes permitting the activities by the facilities subject to compliance with statutory and rule requirements. Watson wishes to operate a solid waste facility in Newberry, Florida. In particular, Watson seeks to operate a C&D facility for off-site disposal of C&D debris to be placed where sand has been mined. Watson would pursue this enterprise by using a general permit, as allowed by DEP. Petitioner, City of Newberry (the City), is a political subdivision of the State of Florida. It opposes Watson's use of a general permit to conduct business as a C&D facility, based upon the belief that Watson has not demonstrated compliance with regulatory provisions that would allow Watson to use a general permit. Petitioner, Citizens for Watermelon Pond, Inc. (Citizens), is a corporation constituted of persons who oppose the use of the general permit for the same reasons expressed by the City. On July 21, 1994, Watson noticed DEP that it intended to use a general permit to operate a C&D facility. On July 29, 1994, a notice was published in the Gainesville Sun, a local newspaper, concerning the pendency of the use of a general permit to operate the C&D facility in Newberry, Florida. On August 12 and 16, 1994, the Petitioners filed petitions seeking an administrative hearing on the use of a general permit by Watson to operate the C & D facility. On August 19, 1994, DEP issued a Notice of Denial of the permission to use a general permit to operate the C&D facility. This permit request was under an arrangement between Watson and a co-applicant, Whitehurst. Following the Notice of Denial, no further action being requested by the applicants, DEP issued an order closing its file. In December 1994, in its name only, Watson resubmitted an application to use a general permit to operate the C&D facility in question. The level of consideration at that time was as a pre-application review. This was followed by a formal notice by Watson and application to use a general permit to operate the C&D facility. The formal application was filed on January 17, 1995. On January 24, 1995, notice was published in the Gainesville Sun concerning the more recent intention to use a general permit to operate the C&D facility. On February 6, 1995, Citizens filed a verified petition opposing the use of the general permit contemplated by the January 17, 1995 application. Two days later, the City filed a verified petition in opposition to the most recent request to use a general permit to operate the C&D facility. On February 15, 1995, DEP gave notice that it did not object to Watson's use of a general permit to operate the C&D facility. Watson's most recent request to use a general permit to operate a C&D facility was made on a form provided by DEP in accordance with Rule 62- 701.900(3), Florida Administrative Code. The application to use a general permit was sealed by a professional engineer. The legal description of the property in question is described in the application. It is located in Newberry, Alachua County, Florida. The site location for the proposed C&D facility is one and one-eighth mile south of Southwest 46th Avenue on the east side of County Road 337 in Newberry, Florida. Documentation has been provided which identifies the legal authorization to use the property as a C&D facility. The C&D facility has a planned active life of 50 years. It is intended that the sand that is excavated will be replaced by C&D debris at a similar grade. The mailing address and telephone number of the C&D owner and operator is identified. Watson is the owner/operator. There are 158 acres within the proposed site. Approximately 143 acres would be used in the C&D operation by mining sand as a prelude to recontouring the site by placing the C&D debris. It is intended to excavate tan sand and silty sand to a depth of 20-30 feet. Although Watson anticipates excavating sand to a depth of 30 feet, bore hole data reveals the existence of sand below that depth. Watson does not intend to excavate below 62 feet mean sea level (MSL). In any event, it is not the intention to excavate below the interface of the sand and underlying sandy clays. Once the sand has been excavated, it is anticipated that the bottom of the C&D disposal area will be approximately 15 feet above the piezometric water table associated with the Floridan Aquifer, according to the applicant. The proposed site is located in rolling terrain, whose elevations range from approximately 80 feet MSL to 100 feet MSL. To support the use of a general permit, Watson has provided a site plan with a scale not greater than 200 feet to the inch, which identifies the project location, with proposed disposal areas, total acreage of the site and of the proposed disposal area, and other relevant features that exist on or within 500 feet of the site. The property boundaries are identified. The site would be fenced. Access to the facility would be controlled by a locked gate on County Road 337. The gate would be open during daily operations. The site does not contain surface water. There being no surface water, the C&D facility does not require a surface water management permit from the Suwannee River Water Management District. The site does not present a problem with stormwater runoff. A potable well is located within 500 feet of the property boundary. However, placement of C&D debris would be offset by a 500-foot buffer from the well. Wetlands are located 2,100 feet from the southern edge of the proposed site in the eastern part of the adjacent Whitehurst parcel. Within 3,000 feet of the proposed site is an old phosphate mining pit on the Whitehurst parcel, and 6,200 feet from the proposed site is the northern-most unnamed pond associated with Watermelon Pond. The site is not susceptible to flooding at present. The sand mined at the proposed site would be used to build roads and for foundations for houses and other buildings. Clay removed from the building sites to make room for the sand would be placed in the C&D facility. The material that is removed from building sites and substituted by sand fill is clay with a high shrink and swell factor. That material, together with flint rocks, tree limbs and stumps, would be transported to the C&D facility by Watson's dump trucks. At present, Watson has 20 dump trucks. The dump trucks hold 20 yards each. In addition to those materials removed from Watson job sites by dump trucks, Watson has approximately 36 roll-off dumpsters which hold 20 yards each. Two Watson trucks are available to transport the roll-off dumpsters to the C&D facility. The roll-off dumpsters are placed on construction sites, not exclusively Watson's, and construction materials not used in the building process would be placed in the roll-off dumpsters for disposal at the C&D facility. Approximately 70 percent of the fill material to be placed in the C&D facility would be unsuitable soils, trees, limbs and stumps. The remaining material would be the C&D debris from construction at sites where the dumpsters have been placed. The dump trucks that hold the clay, limbs and stumps would be loaded by Watson employees, who can control what is placed in the trucks. Watson would not control what is placed in the roll-off dumpsters at other construction sites. The Watson dump trucks from job sites directly related to its activities would arrive at the C&D facility and dump their loads for compaction. Those loads would not be spotted for unsuitable fill materials. By contrast, the roll-off dumpsters would be examined at the construction site by the Watson driver. If the driver discovers excessive amounts of material not classified for C&D fill, contact would be made with the Watson office and the material taken to the Alachua County landfill for disposal. If the driver picks up the dumpster at the construction site and there are limited amounts of material not suitable for disposition at the C&D facility, the dumpster would be taken to the C&D facility. The material would be spread out, and a spotter would segregate materials that are not suitable for C&D fill. The unsuitable material would be placed in temporary containers at the disposal site and transported off-site to a permitted landfill or other appropriate facility. Some material brought to the landfill would be recycled. Woods, such as pine or hardwood would be recycled. The limbs and stumps would be placed in the pit as fill. Copper, aluminum, steel, iron, and any other metal would be recycled. The metals would be sold to a scrap-iron facility. An employee at the landfill would keep the money earned from recycling. Metal embedded in broken concrete would be used as fill. The C&D facility would be operated by two persons: one, a loader/operator who loads the dump trucks with the sand that is being excavated; the second individual, a bulldozer operator who pushes the dump truck loads of clay, limbs, and stumps into the fill area and spreads them. He would also spot the roll-off dumpsters and segregate the fill material from unsuitable material. The sorted construction material to be used as fill would be pushed into the working face of the pit, where the tree limbs, stumps and clay would have also been placed. It is anticipated that six to ten roll-off dumpsters with C&D material would be brought to the C&D facility on a daily basis. The amount of unsuitable material that must be sorted from the dumpsters would vary with the individual loads. Watson operates an existing C&D facility in Alachua County, Florida. The proposed C&D facility would be similar in its operation. Based upon the experience in the existing facility, there is no indication that the proposed C&D facility could not be adequately operated by two employees, taking into account the need to segregate unsuitable material before filling. The spotter would receive verbal training concerning his duties. The training provided the spotter is on-site training. He would be reminded once a week of the need to do an adequate job of looking for unsuitable materials. At present, Alachua County inspects the existing C&D facility on a weekly basis and reminds the spotter at that facility what is appropriate for placement and what is not. The expectation is that the same function would be performed at the proposed facility. If sinkholes are encountered in excavating the sand, the equipment operator would contact the Watson office. In turn, Watson would contact its consulting engineer to address the problem, to include placing a plug or cap to repair the breach caused by the sinkhole. In the event that limerock is encountered in the excavation, a clay cap will be placed to prohibit leachate from flowing into the ground water. Areas where limerock is located at higher elevations and not covered by clay present the greatest risk for sinkhole formation. The period between excavation and fill will be approximately two years, leaving the site exposed at the level of excavation before fill is replaced. When the site is closed, the front-end loader operator and bulldozer operator will spread 24 inches of soil as a cap and grade the site in preparation for planting of pine trees. The soil material would be constituted as six inches of top soil suitable for planting pine trees. The remaining 18 inches would contain clay with high shrink/swell properties. The planting of pine trees would be done through a contract forester. The equipment operated at the facility would employ approved muffler systems. Odor generated by the facility is not anticipated to be a problem, in that household garbage, if found, would only be temporarily maintained, pending placement in an appropriate landfill. The site will be examined on a weekly basis to remove blown "litter". Proper provision is made for maintenance of slopes and compaction of fill material as it is placed. Through the application process noticing DEP that Watson intends to use a general permit to operate its C&D facility, DEP has been informed of the location of the proposed site. DEP would have permission to inspect the site during normal business hours. In response to Rule 62-701.420, Florida Administrative Code, Watson conducted a geotechnical investigation and prepared a report to support the application for a general permit. In support of the application Kenneth J. Hill, P.E. investigated the subsurface conditions at the proposed site through drilling activities. The drilling was done at the site and adjacent to the site. In May, 1995, Douglas L. Smith, Ph.D., P.G., conducted an electrical resistivity study (ER) at the site to investigate the subsurface conditions. Thomas H. Patton, Ph.D., P.G. and Charles Swallows, P.E. assisted in the investigation of the subsurface conditions at the site. Ralph E. Eng, P.E., signed and sealed the application for general permit for the proposed C&D facility. In rendering a report following his investigation of the subsurface conditions, Mr. Hill signed and sealed the report and supporting documentation. Likewise, Dr. Smith signed and sealed the report and supporting documentation associated with the ER study, together with Anthony F. Randazzo, Ph.D., P.G. The contribution by Dr. Patton and Mr. Swallows to the geotechnical investigation did not include signing and sealing a report and documentation. Nonetheless, Dr. Patton and Mr. Swallows, when testifying concerning the permit request, as with other professional witnesses, were found qualified to offer testimony consistent with their professional credentials and factual knowledge. 1/ A foundation analysis to determine the ability of the foundation to support the loads and stresses imposed by the fill material revealed that the weight of the construction debris was approximately 70 pounds per cubic foot, whereas the weight of the existing sand to be excavated is approximately 100 pounds per cubic foot. Thus, the placement of fill material following excavation would impose less stress on the subsurface than before. No significant settlement of the fill materials is expected to occur, resulting from its weight. The nature and fate of leachate promoted by the placement of fill at the site, in an environmental susceptible to bio-chemical and physical influences in transport through the subsurface, has the potential to adversely impact ground water. Those impacts could possibly cause violations of water- quality standards, ground-water standards, and drinking-water standards. These issues are considered based upon facts associated with the imperatives which must be properly addressed through the geotechnical investigation. That process anticipates gaining an understanding of subsurface conditions, to include the soil stratigraphy and ground-water table conditions. The ground-water table conditions involves estimations of the average and maximum high ground-water table. The geotechnical investigation should also explore the possibility of and address the existence of any sinkholes on the site. No specific testimony was given concerning the degree to which leachate, when present in the ground water at the Floridan Aquifer, might promote water-quality violations. Leachate properties and constituents were described in general terms of water-quality considerations, for example, hardness, nitrates, nitrites, alkalinity, presence of ammonia, chlorides, iron manganese, phenols, barium, arsenic, cadmium, lead, mercury, zinc, TDS and sulfates, urea formaldehyde, plaster, creosote, glues, and mastic hardeners. The evidence presented concerning the parameters for water quality did include a reference to barium, ranging from .5UG/L to 8UG/L in basically similar circumstances. The fill material can influence the natural PH by creating acidic conditions causing the PH to fall from a neutral 7.0 to 5.5 to 6.5. The process that takes place over time with the fill material also releases gases, such as methane, hydrogensulphide, and carbon dioxide. Rainwater falling on the ground's surface forms the basis for transporting the leachate through the subsurface. Only the Floridan Aquifer is potentially at risk, there being no surface water bodies or surficial aquifer at the site. Taking into account rainfall disposition by evapotranspiration, storm- water runoff, and subsurface infiltration, without certainty as to the amounts in those processes, it can be said that a significant amount of rainfall is available through infiltration to recharge the Floridan Aquifer and to transport leachate promoted by the fill. This is borne out by the absence of surface water bodies and a surficial aquifer on the site. To gain basic information concerning the subsurface conditions, Watson had 14 standard penetration test borings conducted by Mr. Hill and his firm. Those borings were advanced to depths of 35-72 feet. Additionally, three auger borings were performed to a depth of 40-50 feet. The auger borings were at sites A-1, A-2, and A-3, performed on April 17, 1993. In July of 1993, standard penetration test borings were performed at sites B-1, B-2, B-3, and B-4. In April of 1994, standard penetration test borings were performed at sites B-5, B-6, B-7, and B-8. In September of 1994, standard penetration test borings were performed at sites B-9, B-10, B-11, B-12, B-13, and B-14. The borings that were performed at the proposed site were at B-2, B-5, B-6, B-9, B-10, and B-14, for a total of six borings. The other borings were performed on the adjacent parcel. The borings at the proposed site were widely dispersed over the 143 acres contemplated for excavation and fill. The borings on the adjacent parcel, referred to as the Whitehurst parcel, were widely dispersed over 475 acres. Logs of the soil borings were prepared depicting the findings in the subsurface. The soil stratigraphy found in the borings was varied with sand, clayey sand, sandy clay and limerock present in some but not all borings. The sands that have been described are Aeolian. The sands are remnants of an ancient coastal dune system. Soil permeability tests were conducted on a limited basis at boring B- 9 at a 25-foot sample depth. The tan and orange clayey sand described had a co- efficient for permeability of 1x10-6. That sample and others described were obtained through a split-spoon. At B-12, at 35 feet, tan and orange clayey sand was found with a co-efficient for permeability of 2.6x10-8. At B-13, at 30 feet, tan and orange clayey sand was found and tested as 2.0x10-8 for the co- efficient for permeability. At B-14, at 30 feet, tan and orange sandy clay was found with a co-efficient for permeability of 9.6x10-9. In describing the soils, sieve analysis was not performed to more precisely classify the sediments encountered. This description of the strata is by appearance and texture. The clayey sand and sandy clay found in the borings retard discharge of the leachate to the ground water in the Floridan Aquifer based upon the permeability in those soils. Generally stated, the tan sands described have a co-efficient for permeability of 10-1 to 10-4. These sands are highly permeable, presenting an easy opportunity to convey the leachate contained in the infiltrating rainwater. Anomalous findings concerning soil permeability are shown at B-4, an off-site location, which portrays only sand in the boring. Also, B-9, which was drilled four to five feet east of a known sinkhole at the site is noteworthy in that the boring log describes tan and orange sandy clay, with trace limerock below 30 feet. This is in contrast to the field notation by the driller of the "p" for push and drilling rod "free fall" from 38 feet BLS to 42.5 feet BLS before encountering limerock, connoting a possible cavity in the 38-foot BLS to 42.5-foot BLS region. The karst feature that is located in the area where boring B-9 was conducted will be surveyed and marked with fence posts prior to excavation. No excavation will be conducted within 200 feet of that site. In addition to the phenomenon at the B-9 boring area, sinkholes at the surface were observed one-half to three-quarters of a mile northeast of the site. Sinkholes can occur when the placement of fill changes the hydraulics and loading in a karst environment. Finally, at B-6, limerock was encountered above the 46.9 feet MSL regional piezometric surface of the Floridan Aquifer. That limerock is considered part of the aquifer system. The head pressure at that location was not sufficient to force the ground water from the Floridan Aquifer. The more typical experience was as shown in B-5, where the surface of the limerock was lower than the regional piezometric surface. In B-5, ground water was not encountered until the clayey layer was breached and water rose in the drill hole. On occasions, such as the experience in B-5, there was an indication that Artesian conditions existed at those places. At the locations where the Artesian conditions were experienced, the Floridan Aquifer is confined. At B-6, where the limestone rises higher than the regional piezometric surface, the Floridan Aquifer is not confined. The bore hole at B-2 was terminated before breaching the clayey layer, and ground water was not encountered. Watson's consultant Hill considered that the ground-water table was found within the Floridan Aquifer at the site whose regional potentiometric surface was 46.9 MSL. He perceived that the findings showed ground water at 45 feet MSL constituting the average for the site. Watson estimated that the "seasonal high" ground-water table at the site was 48 feet MSL. The term "seasonal high" is equated to maximum high. Watson claims that the fluctuation in the ground-water table would be only a few feet. This would mean that the 45 feet MSL from bore hole data would represent not only the average across the site but the average value at the site at any point in time during the year. Watson makes this assertion notwithstanding that the borings were made over two years during different seasons. The basis for the estimate of maximum high ground-water table is not evident. In Dr. Patton's remarks in the application, there is a reference to the fact that the lowest encountered elevation for the Floridan Aquifer was 45 feet MSL and the highest was 55 feet MSL, making the average 50 feet MSL. This runs contrary to the remarks by Hill in which Hill said the elevation in the region was 46.9, the elevation detected was 45, and that the seasonal high would be 48. The only borings that were made in which the log reflects the MSL elevation and the boring depth are borings that were conducted in April 1994. On that date, the boring depth at which ground water was encountered varied from 37-43 feet and the MSL depth varied from 39-47 feet. If only the information for B-5 and B-6 on the site proper is used, those two data points associated with the borings on April 1994 reveal ground water at an excavation depth of 37 feet and between 45-47 feet MSL, respectively. Overall, without reference to MSL, the depths at which the ground water was encountered in the borings varied from 19-44 feet, if encountered. Although it is not shown in the boring log what the relationship is to MSL, at B-9, water was found at a drilling depth of 38 feet; at B-10, at a depth of 36 and one-half feet; at B-2, no water had been encountered at a drilling depth of 50 feet; at B-14, no water had been encountered at a drilling depth of 35 feet; at B-1, water was encountered at a level of 44 feet; at B-3, water had not been encountered at the concluding depth of 50 feet; at B-4, water had not been encountered at the concluding depth of 50 feet; at B-11, water was encountered at a drilling depth of 31 and one-half feet; at B-12, water was encountered at a drilling depth of 19 feet; at B-13, water was encountered at a drilling depth of 21 and one-half feet. Where elevations were measured for the water table in the bore holes, the holes were left open until the drillings had been concluded. Then the measurements were made. In this project, the consultant did not equilibrate the ground-water table by the traditional method of leaving a piezometer in the bore hole to maintain its integrity for a day before making the measurement. Watson has not provided sufficient information and explanation to determine a proper estimate of the average and maximum high ground-water table across the site. Returning to the ER investigation, it involved 39 soundings, which is roughly equivalent to drilling bore holes. The sounding profiles were determined through Wenner-Array Sounding and Lee-Directional Equipment. This technique involves the passing of an electrical current underground and measuring its resistance to flow. The expectation is that earth materials, for example, clay, sand, limestone, and cavities will resist the flow of electrical current differently. Substantially greater contrast in the degree of resistance, anomalies, is used to identify and locate earth materials, as well as the presence and shape of cavities. The sounding measurements reveal two- dimensional detail below the surface at progressively-greater depths. Lee- Directional measurements determine the direction of higher or lower resistivity along the survey line. While in the field, electrodes are placed in the ground at equal distances from one another. After a measurement, this distance is increased in an orderly fashion. The greater distance between the electrodes, the greater the depth of penetration. The ER equipment's electrical current has the capacity to penetrate through clay and into lower features in the subsurface. Subsurface from depths five to 100 feet were examined in this study. Within the 39 groundings surveyed, various soils were encountered. Generally, a thick cover of unconsolidated sand was found overlying clayey sand, with a clay layer varying in thickness and limestone found in some soundings, but not others. Where limestone was detected, it was at deeper levels in the southwestern part of the site. Because ER cannot distinguish between clayey sand and sandy clay, the area where those soils are found is referred to in the report as a thinner clayey sand layer. Also, in some places the upper surface of limestone has suffered weathering or deterioration and may appear as the lower part of the clay unit in terms of its electrical properties. The general portrayal in the ER study concerning the soil stratigraphy, wherein reference is made to dry sand up to 30 feet in thickness overlying a thinner clayey sand layer, approximately 10 feet in thickness, overlying a relatively thick clay layer from 10-60 feet and then limestone, does not coincide with the complexity in the stratigraphy found in the soil borings. In the ER study, at stations 8 and 10, voids were encountered. The nature of those voids is unexplained by this investigative process. At station 8, the void was found at approximately 100 feet deep. At station 10, the voids were at 50 feet and 100 feet deep. At station 14, anomalous findings were explained as the placement of fill and organic material during land-clearing operations. The suggestion in the written report, which summarizes the findings in the ER investigation, that a water table was encountered at approximately 40 feet deep, coinciding with the top of the clay layer, is contrary to the findings in the soil borings. To the extent that finding is intended to suggest that there is a perched water table or surficial aquifer above the clay layer, that view is contrary to other evidence adduced at hearing and is rejected. Like the soil borings, the ER soundings examined very discreet areas, but revealed less discreet information. This investigative process is not designed by itself to resolve disputes concerning the character of the subsurface, taking into account statutory and rule requirements for issuing a general permit. To portray the subsurface conditions, in June 1995, Petitioners undertook another basic study by employing ground-penetrating radar (GPR) to reveal the subsurface conditions. Again, GPR, like ER, affords limited insight into the conditions in the subsurface. More precise information than is revealed in the results from the GPR study would be needed to understand the subsurface conditions. GPR is comprised of several pieces of equipment that are connected with cables and a power source. This equipment is mobile. It uses a transmitter and receiver antenna that essentially glides along the ground surface. A signal is emitted through the transmitter. It perpetrates into the ground. It is reflected off materials of different electrical properties back to the receiving antenna and charted. The record that is made is continuous. Unlike ER, GPR is capable of detecting small anomalies in the subsurface. In employing the equipment in this investigation, Petitioners' consultant was looking for either stratigraphic or water-table reflectors and anomalous conditions. The experience at this site was comparable to the experience at other sites in gaining an understanding of how geologic materials are deposited. The GPR investigation covered approximately 10 percent of the site. Four lines were traversed east to west. Two lines were traversed north to south, and two other lines were traversed on a diagonal. GPR will not significantly penetrate clay. Its ability to penetrate is dependent in some measure upon the nature of the clay unit encountered. However, GPR reveals contrasts in the conductivity of clay, when compared to the overlying sand. The greater the contrast, the greater the reflection event. In this connection, the presence of moisture can slow or prohibit the electromagnetic energy generated by GPR. The GPR study revealed a substantial number of subsurface anomalies that might be indicative of possible access for leachate generated by the placement of fill to enter the Floridan Aquifer. These anomalies might represent sand columns and cover subsidence sinkholes. Any sinkholes on the site would be expected to be "cover subsidence"- type sinkholes. Those sinkholes occur through a process in which overlying strata slowly subsides into the sub-adjacent karst feature, rather than suddenly collapsing. Sinkholes develop rarely, but pose more risk of development in areas where sinkholes have occurred previously. Sinkholes are not always seen at the land surface. Sinkholes can present a risk to ground water in the aquifer in view of solution cavities found in the limestone which is part of the aquifer, thus allowing leachate to flow through the cavities into the ground water. Some anomalies found in the GPR study were more significant. One that was observed in the third traverse was 100 feet wide by 80-90 feet deep. There is an indication that this area might be filled with sands, creating a more ready access to the lower subsurface than would be expected with other soils. Another anomaly discovered was 200-300 feet long and 400-500 feet wide, approximately 50 feet below the surface. Overall subsurface conditions are not readily understood. Watson, through its consultant, suggests that the site is part of the Newberry Sand Hills region of the Brooksville Ridge system. As such, karst activity has proceeded in a slower manner than other places in Alachua County, with no presently active karst conditions. In opposition, Petitioners assert that the site is part of the Brooksville Ridge System, which is an internally-drained area of karst-dominated highly fractured terrain, according to its consultants. If Petitioners are correct, those circumstances lead to solutioning of the limestone and are not indicative of area of continuous impermeable clay layers found at the site as part of the Hawthorne formation that Watson's consultant surmises. The exact nature of the site concerning factors that must be considered in this permit application have not been adequately resolved in this record. While it is sufficiently evident that the Floridan Aquifer is not confined, it is unclear whether the circumstances at the site present unacceptable risks to the ground water, in view of existing subsurface conditions. From the record, the proper manner to resolve the issue would be to perform more soil borings on the site proper to identify the subsurface conditions concerning soil stratigraphy and ground-water location.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered which denies Watson the use of a general permit to operate the proposed C&D facility. DONE AND ENTERED this 7th day of August, 1996, in Tallahassee, Florida. CHARLES C. ADAMS, Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 7th day of August, 1996.
Findings Of Fact Bray is the owner of and lives on property located at 5550 Pine Hills Road, Orlando, Florida. He operates a solid waste disposal site on this property. By application dated June 6, 1977, and revised June 13, 1977, Bray applied to DER for an Operation Permit for a Solid Waste Resource Recovery and Management Facility pursuant to Chapter 17-7, Florida Administrative Code. At that time, Bray held a Temporary Operating Permit which had been issued on February 4, 1976. In Bray's application materials, which included the application dated June 6, 1977 and revised June 13, 1977, and letters from Bray to DER dated June 8, 1977, and June 30, 1977, Bray proposed an alternate procedure pursuant to Rule 17-7.05(3) (q) for operation of his landfill which procedure would permit Bray to cover, spread and compact the fill material in a manner different from that specifically set forth in Rule 17-7.05, Florida Administrative Code. DER did not consider Bray's request for an alternate procedure, but responded by letter stating that Bray must apply for a variance pursuant to Rule 17-1.25, Florida Administrative Code, and recommended denial of Bray's application for a permit for the following reasons: No provisions were made for daily cover. Refuse was not spread in two (2) foot layers. No intermediate cover was applied within one week of cell completion. No cover materials were stockpiled. During the testimony presented, DER acknowledged that the fourth reason given for denial of the permits-no cover materials were stockpiled-is not a requirement of the Rules and is not a valid reason for denial of a Permit Application. This Hearing Examiner agrees and finds that Chapter 17-7, Florida Administrative Code only requires that the site have an adequate quantity of acceptable earth cover available. See Rule 17-7.05(1) (c)3, Florida Administrative Code. Bray presented adequate testimony demonstrating that sufficient acceptable cover material was available at his site. Bray conceded at the hearing that it was still his intention to operate the landfill site without daily cover, intermediate cover and compaction as required by DER. Bray's principal contention is that compaction and daily cover are not necessary for a landfill which accepts only non-putrescible waste. Bray urges that the attenuation of leachate, prevention of fires, prevention of settling and ponding of water which provide breeding grounds for mosquitoes and other vectors and reducing the area of land needed to dispose of solid waste are justifications for the requirements of compaction and daily cover of solid waste which may not be present at non-putrescible landfills. Bray concludes that the absence of these problems at his landfill obviates the necessity for the application of the provisions of the rule requiring daily and intermediate cover and compaction. However, Bray has not met his burden of establishing that non- putrescible waste does not require compaction and daily cover. There are multiple reasons for the requirement of compaction and daily cover of solid waste. When solid-waste is spread to approximately a 2-foot thickness and then compacted to a 1-foot thickness, followed by the daily application of a cover of 6 inches of compacted earth, a layering effect is created which helps attenuate, if not prevent, the formation of leachate from both putrescibles and non-putrescibles which may be contained in the waste. Leachate is a liquid that has percolated through solid waste, usually originating as rain, which contains dissolved or suspended material that may contaminate ground water supply. Leachate occurs in landfills that accept putrescible material as well as landfills that accept only non-putrescibles. Compaction and daily cover consequently slow, if not prevent, the contamination of ground water supplies. The formation of leachate containing various chemicals which would have adverse affects on the human body is expected when water percolates through strictly non-putrescible waste Commonly discarded non-putrescibles such as metals, plastics, ashes, rocks and dirt from an industrial site, miscellaneous organics, heavy metal solutions and sludges, organic solvents and oils, caustic and acid solutions, inorganic chemical solutions and sludges, pesticides and fungicide wastes, paint and ink wastes, asphalt roofing and paving material, explosive waste and radioactive waste are probable sources of leachate contamination. The process of leachate formation from non-putrescibles involve the physical and chemical reaction of compounds in the non-putrescibles with the water percolating through them. The contamination of ground water supplies by leachate from either a putrescible or non-putrescible site constitutes a threat to the health, safety and welfare of the public as many of the contaminates are toxic and have adverse affects on the human body. In particular, leachate from non-putrescibles may contain toxic metal solutions, carcinogenic pesticides and other organic compounds as well as toxic inorganic compounds. Another reason for compacting and daily cover is the prevention of fires. Exposed, non-putrescible wastes can ignite and result in serious dump fires. Daily cover, if applied, serves as a fire break and eliminates the fire hazard created by exposed combustible non-putrescible wastes. Furthermore, compaction and daily cover prevent settling and ponding which would contribute to both downward flow' of water through the solid waste and the creation of breeding grounds for mosquitoes and other vectors. Compaction and daily cover contribute to the general aesthetics of the site and reduce the area of land needed to dispose of solid waste Bray has attempted to show that his method of operation effectively screens putrescible wastes from the site and otherwise adequately protects the public health, safety and welfare. However, the evidence which belies the assertion, shows that putrescibles have, in fact, been dumped at Bray Landfill. Coliform readings obtained in samples from monitoring wells at the Bray property can reasonably be attributed to putrescible matter on site. Birds have been observed feeding on site and these would not be feeding on non-putrescible wastes. The policing techniques are largely ineffectual. The site contains unopened trash bags with undisclosed contents as well as observed putrescible garbage. Trucks enter the site and dump their loads without inspection. Two major dump fires have occurred at the Bray Landfill during the past four years.
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.

Findings Of Fact The Board of County Commissioners of Monroe County is responsible for maintaining a solid waste management program for the unincorporated areas of the county. The portion of the Florida Keys known as the "lower keys" between Pigeon Key on the north and Key West on the south is such an area. Prior to July 1, 1977, solid waste from this area was dumped at a site located on Middle Torch Key. Until approximately two years prior to the hearing, the Middle Torch Key dump site had been operated by private companies. The private companies apparently could not operate the site profitably under rules and regulations promulgated by the Department, and the County took over operation of the site. The site served as the solid waste dump for the lower keys until July 1, 1977. The Department had issued a temporary operating permit for the site, and open burning was permitted. The temporary permit expired on July 1, 1977. The Middle Torch Key dump site was never operated in full compliance with the Department's rules. The temporary operating permit was issued for the apparent purpose of allowing the County an opportunity to develop a system that could be operated accordance with the Department's rules. The County purchased a site on Cudjoe Key in the lower keys with the intention of utilizing it as a sanitary landfill. The instant proceeding is the culmination of the County's effort to obtain a permit to operate the Cudjoe Key site. The County has been utilizing the Cudjoe Key Site as a sanitary landfill since July 1, 1977. The Petitioners are homeowners in a residential subdivision which is located between three fourths of a mile and one mile from the proposed landfill site on Cudjoe Key. They object to operation of a sanitary landfill in such close proximity to their homes. In order to meet its obligation to maintain a solid waste disposal system, and in order to comply with DER regulations, the County needed to locate a landfill site in the area of the lower keys. The County lacks resources to truck solid waste from the lower keys to any sites in the upper keys, or on the mainland. Tie Cudjoe Key site was chosen for a sanitary landfill for two reasons. First, it was relatively isolated and had been used as a dump before. Secondly, it was for sale, and the County could afford to purchase it. The Cudjoe Key landfill site is not visible from any highway or from any residences or businesses. The site adjoins other public property, and is next to electric company property. The average height of the site is seven to eight feet above sea level. The site is located in close proximity to a borrow pit, and fill is thus obtainable at a fairly inexpensive rate. The County's plan of operation basically is to place solid waste on the site, and to cover it with six inches of landfill at the end of each working day. The site, if used in this manner, would have a useful life of approximately three years. If incineration techniques are eventually permitted, the life expectancy of the site would be increased to approximately twenty years. It does not appear that there is any ideal site for a sanitary landfill in the lower keys. There is very little dry land available that has not been previously developed. It appears that the best present alternative for solid waste disposal for the lower keys would be a joint venture with the City of Key West to desalinate salt water through incinerating activities at a site on Stock Island located just south of Key West. Neither the City of Key West, nor the unincorporated areas of the lower keys produce sufficient solid waste alone to make such a project feasible. Thus far a solution of this sort has not been politically feasible. Aside from this possibility, it appears that the proposed Cudjoe Key site is the best location for a sanitary landfill in the lower keys. The site on Middle Torch Key, which was previously operated as a dump would not comply with the Department's rules. The site is under water at high tide. In order to develop the site so that it would comply with the Department's regulation, a very large expenditure would be required. A copy of the County's completed application to the Department was received in evidence at the hearing as Department's Composite Exhibit 1. The application is complete, and contains the material required under Rule 17-7.05,, Florida Administrative Code. No competent evidence was presented at the hearing from which it could be concluded that the proposed Cudjoe Key landfill site does not comply with statutory requirements, or with the requirements set out in the Department's rules and regulations. Considerable evidence was offered from which it could be concluded that the site has not been operated in full compliance with the Department's regulations since July 1, 1977. Clearly the County has been operating the site since that date without a permit issued by the Department. It is apparent that the Department has not sought to take action against the County due to the pendency of this action. Pictures offered at the hearing, and observations made at the view of the site demonstrate that the required daily cover of solid waste has not been applied at the site. These violations could, and should if they continue, result in enforcement action being taken by the Department. The violations, and anticipated violations cannot, however, constitute grounds for denying a permit to operate a sanitary landfill site which complies with the pertinent statutes and rules and regulations.
