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 or about August 4, 1990, Bio-Med Services, Inc., (hereinafter "BMS") submitted to the Department of Environmental Regulation (hereinafter "DER"), an application for the construction of a biohazardous waste incineration facility (hereinafter "facility") to be located on approximately 5.5 acres in the City of LaBelle Industrial Park. The application was prepared, signed and sealed by Robert A. Baker, Professional Engineer, and was signed by Gary V. Marsden, president of BMS. BMS is a wholly owned subsidiary of Bio-Med Management, Inc., (hereinafter BMM), and was formed for the express purpose of making application for construction of the facility at issue in this case. Gary V. Marsden has held the position of president of BMS for approximately one and one-half years. Prior to becoming BMS president, Gary Marsden was a telephone equipment salesman. Gary Marsden's father, Clarence, is president of BMM, and a director of BMS. The BMS business plan indicates that Clarence Marsden was integral to the formation of BMS, was the primary contact between BMS and engineer Baker, and will act as salesman for BMS. Clarence Marsden has been convicted approximately four times on felony counts related to illegal drug activities. Neither Marsden has any experience related to construction or operation of biohazardous waste incineration facilities. According to the first application, the incinerator facility will utilize two "Consumat-1200" incinerators and one "U-Burn 12060" incinerator. 1/ The Consumat-1200 units are each capable of incinerating approximately 2,000 pounds of waste hourly. The U-Burn incinerator is capable of incinerating 250 pounds of waste hourly. The total waste incineration capacity of the facility is approximately 50 tons daily. The waste to be incinerated consists of biological and biohazardous wastes, primarily from hospitals and medical offices. The facility would not be authorized to incinerate hazardous or radioactive wastes. The application seeks approval to construct an incinerator facility which could operate 24 hours daily, seven days weekly, on a year-round basis. Although the incinerators would be shut down for maintenance and repairs, the applicant hypothesized the constant operation of the facility for the purpose of predicting emissions levels. The air pollution control (hereinafter "APC") system proposed in the first application includes venturi scrubbers, caustic scrubbers, and a 50 foot tall, 30 inch diameter discharge stack. On or about April 19, 1991, BMS submitted amendments to the first application. The amendments, (hereinafter the "second application") were prepared and signed by Mr. Baker. The amendments deleted the venturi scrubbers/caustic scrubbers and substituted dry hydrated lime injection scrubbers and baghouses. The amendments also altered the discharge stack dimensions to provide for a stack height of 65 feet and a diameter of 40 inches. The second application also included a bypass stack to provide for APC system malfunctions. Such bypass stacks provide for uncontrolled discharge of emissions into the atmosphere, when such emissions could further damage a malfunctioning APC system. On or about September 24, 1991, an application was submitted by Eastern Grading, Inc. 2/ for a permit to construct a biohazardous waste incineration facility to be located on a site outside the City of LaBelle, rather than at the LaBelle Industrial Park. According to the third application, the incinerator facility still proposes to utilize two "Consumat- 1200" incinerators and one "U-Burn 12060" incinerator. The third application deleted the bypass stack system intended to handle emergency situations and substituted a proposed crossover mechanism. The Eastern Grading application, (hereinafter the "third application") prepared and signed by Mr. Baker and signed by Gary Marsden as president of Eastern Grading, Inc., is the application at issue in this proceeding. Subsequent to the filing of the third application, BMS has now abandoned plans to locate the facility on the site identified in the third application and instead seeks approval to construct the biohazardous waste incineration facility at the LaBelle Industrial Park site identified in the first application. The proposed site for the facility is located approximately 4,900 feet from the City of LaBelle Public Water Treatment Facility. The raw water supply comes from shallow wells southwest of the city, and is stored at the treatment plant in open holding areas. After sand-filtering and softening, the water is stored in vented tanks. Based upon the proximity of the water treatment plant to the incineration site, there is high potential for impact on the local water supply by the emissions discharged from the incineration facility. The site of the proposed facility is located next to the Cross Tie Mobile Home Estates Subdivision, approximately 75 feet from the closest residence, approximately 2,000 feet from a senior citizen service center, and approximately 3,700 feet from a local nursing home. It is likely that some individuals in the nursing home may be regarded as particularly health sensitive, as are a number of residents of Cross Tie Mobile Home Estates Subdivision who suffer from respiratory illnesses and who testified during the proceeding. The site is approximately 4,600 feet from a local elementary school, approximately 4,400 feet from an intermediate school, approximately 7,400 feet from a middle school, and approximately 8,600 feet from a high school. Persons with existing respiratory illnesses, elderly persons, and children are regarded as "sensitive receptors" and are substantially more at risk through exposure to airborne chemical pollutants than is the general population. Based upon the proximity of the incineration site to such sensitive receptors, there is high potential for impact on such persons by the emissions discharged from the incineration facility. There was no site-specific analysis of the proposed facility done by either the applicant during preparation of the application or by the DER during review of the proposal. The applicant has provided no data related to potential heath risks posed by the proposed facility. The DER has not specifically analyzed such health risks. The third application states that various requirements of the Department will be met. The application provides as follows: "Each incinerator will have the following equipment and operational requirements in order to comply with the requirements of FAC 17-2.600: Particulate emissions will not to (sic) exceed 0.020 grains per dry standard cubic foot (gr/dscf) corrected to 7% oxygen (O2). Hydrochloric acid (HCI) emissions to be reduced by 90% by weight on an hourly average basis. At least one second residence time at no less than 1800 F. in the secondary combustion chamber. An air lock system designed to prevent opening the incinerator doors to the room environment and to prevent overcharging. Carbon monoxide (CO) concentrations in the stack exhaust gases of less than 100 PPMv, dry basis, corrected to 7% 02 on an hourly basis. The secondary combustion chamber to be preheated to 1800 F. prior to burning and maintained at 1800 F. or greater during active burning of wastes. All incinerator operators will be trained by Consumat Systems or another qualified training organization. A training plan for the operators will be submitted to the Florida Department of Environmental Regulation (FDER) prior to the start of operations. Continuous monitoring and recording of temperatures and oxygen will be maintained at the exit of the secondary combustion chamber. Operating procedures and calibration requirements will be submitted to FDER upon selection of monitoring equipment. All air pollution control equipment will be functioning properly during operation of the incinerator system. The list of assurances set forth above are a recitation of the requirements of the DER's rules as provided at Chapter 17- 2.600, Florida Administrative Code. The evidence as to specific equipment and operational requirements is insufficient to support the assertion that the facility will meet such standards. As the applicant's professional engineer, Mr. Baker signed and sealed a statement as follows: This is to certify that the engineering features of this pollution control project have been examined by me and found to be in conformity with modern engineering principles applicable to the treatment and disposal of-pollutants characterized in the permit application. There is reasonable assurance, in my professional judgement, that the pollution control facilities, when properly maintained and operated, will discharge an effluent that complies with all applicable statutes of the State of Florida and the rules and regulations of the department. It is also agreed that the undersigned will furnish, if authorized by the owner, the applicant a set of instructions for the proper maintenance and operation of the pollution control facilities and, if applicable, pollution sources. Mr. Baker's certification relates only to his opinion that the facility, properly operated and maintained, will be capable of compliance with Chapter 17-2.600, Florida Administrative Code. The engineering and design of the incineration facility have not been completed. The application states, without qualification, that the two Consumat units will be utilized. The remaining equipment, including the entire air pollution control system, is identified by type of component, but is otherwise not specified. Where equipment specifications are provided, such specifications are qualified by language stating that the equipment installed will meet either such specifications "or their technical equivalents". No actual operating or test data related to any of the equipment or systems proposed for use is included in the application. There is no reliable operating or test data applicable to biohazardous waste incineration facilities available for this particular configuration of components. The application fails to contain sufficient information related to "engineering features" to permit a credible determination as to whether or not the incineration facility will conform with modern engineering principles. The application fails to support Mr. Baker's assertion that reasonable assurances are provided that when properly maintained and operated, the facility will discharge an effluent that complies with all applicable statutes of the State of Florida and the rules and regulations of the DER. Although there is no evidence to establish that the applicant intends not to comply with the requirements of the DER's regulations, the application, reflecting the fairly preliminary design of the incineration facility, fails to provide sufficient information to assure that, once final design decisions are made and the equipment acquired, that such equipment will be compatible and configured in a manner which assures compliance with the DER's acceptable emissions regulations. The applicant has no experience in construction or operation of such incineration facilities. There is no other existing and operating biohazardous waste incineration facility using this configuration of air pollution control equipment. Mr. Baker contends that the completion of final design plans and specifications is a relatively straightforward process, but nonetheless, it has not been done. The Consumat incinerators have already been purchased, are used equipment, and were subject to a cursory inspection conducted by a BMS investor prior to purchase and transportation of the used equipment from the original owner in South Carolina. There is no evidence that structural inspections by a qualified metallurgist are contemplated. The Consumat units are starved-air incinerators. A starved air incinerator consists of two chambers, one primary and one secondary. The inflow of air into the primary chamber is controlled to provide for partial combustion and volatilization of wastes. The maximum temperature of the primary chamber is 1400 degrees F. The gases produced in the primary chamber flow into the secondary chamber where the temperature is maintained through gas burners. The minimum temperature in the secondary chamber is 1800 degrees F. The application provides that the waste gases will remain in the secondary chamber for two seconds. Control of temperature and residence time is the secondary chamber is required to complete the combustion process. The draft permit conditions require the applicant to install, maintain and operate continuous emissions monitoring equipment to record the secondary combustion chamber's exit temperature and oxygen level. Each incinerator will have an oxygen probe and a thermal couple at the secondary chamber exit. The oxygen probe will provide data needed to ascertain whether the combustion process is adequate and permits the correction of oxygen levels to the 7% standard required to measure emissions levels. The thermal couple permits the monitoring of exit temperatures. The draft permit also requires BMS to maintain all testing measurements and calibration data, and other information related to equipment maintenance and adjustments. The Consumat units must be retrofitted to permit the residence time and temperature indicated in the application. The application does not contain design or engineering information related to retrofitting the secondary chambers. The U-Burn unit is, according to professional engineer Baker, a "very unique design of a company that's no longer in existence." The U-Burn would be operated only in conjunction with one of the Consumat units. One Consumat and the U-Burn would each have a separate connection into one of the two APC systems. The application provides no design or engineering data related to the connection of the U-Burn unit into the APC system. The application states that the incinerators will be loaded by means of an enclosed ram feed mechanism which will prevent the incinerator from being opened to the room environment and prohibit overloading of the unit. The enclosed ram feed mechanism has not yet been designed. Two parallel lines of identically sized pollution control equipment are proposed, each line designed to meet the requirements of one Consumat unit and the U-Burn unit. Each line of equipment will include a preconditioner ("quencher"), a lime injection dry scrubber, and a fabric filter baghouse. To control emissions, it is necessary to reduce the temperature of gases exiting the secondary chamber, where the minimum temperature is 1800 degrees F. According to the "Process Description" in the application, the gas stream will be preconditioned by the use of water injection to lower the gas stream temperature to 275 degrees F. The water from the preconditioning process will be evaporated as part of the exhaust gases. The preconditioner will be lined with refractory material to withstand the extreme temperature. The application contains preliminary design specifications for the preconditioner, however the application states that such specifications "or their technical equivalents" will be utilized in the final design, accordingly such specifications are subject to change. There has been no more than preliminary design and engineering work completed for the construction and operation of the preconditioner. The application states that the dry hydrated lime injection system (dry scrubber) and the fabric filter system have been designed to meet the requirements of Chapter 17-2.600 F.A.C. for particulate matter and HCI emissions control. Upon leaving the preconditioner, cooled flue gases move into the dry scrubber. According to the "Process Description" in the application, an ultra- fine, dry hydrated lime (calcium hydroxide) will be injected into the preconditioned gas stream via a metered pneumatic system inside a reactor. Although the velocity of the injection must be sufficient to ensure that the dry lime mixes thoroughly with the flue gases, the application contains no information related to expected injection velocity. Once mixed, the lime reacts with hydrochloric acid to produce calcium chloride. The dry scrubber will collect large particulate matter and will have an airlock system for removal of collected solids. The lime injection rate will be at a minimum of 30% greater than the stoichiometric requirements for the neutralization of the HCI. This system is intended to remove at least 90% of the HCI in the gas stream. The application contains preliminary design specifications for the dry scrubber, however the application states that such specifications "or their technical equivalents" will be utilized in the final design, accordingly such specifications are subject to change. No more than preliminary design work for the construction and operation of the dry scrubber has been completed. Following dry scrubber treatment, the flue gases proceed to a reverse jet fabric filter baghouse. Baghouse technology is a relatively standard methodology of controlling submicron particulate matter (and dioxins/furans condensed on such matter) and heavy metal vapors. According to the "Process Description" in the application, the reverse jet fabric filter will have a maximum air to cloth ratio of 5 to 1. 3/ Under some conditions, a 5 to 1 air to cloth ratio may result in the filter bags becoming clogged with ultrafine particulates. The baghouse is intended to have a removal efficiency of greater than 99% for submicron particulate matter. The application contains preliminary design specifications for the baghouse, however the application states that such specifications "or their technical equivalents" will be utilized in the final design, accordingly such specifications are subject to change. A substantial amount of manufacturer literature related to dry scrubbers, baghouses (including the fabric filter bags), and emissions monitoring equipment is included in the application, but is of no probative value given that the applicant has not committed to using any of the equipment for which literature is included. The application indicates that the incineration facility will include a "crossover" between the two APC systems, to provide for the possibility that one APC system could fail. During such "upset" conditions, there is a substantial potential for visible and fugitive emissions, as well as odors and smoke. The applicant has not yet designed the crossover mechanism and has no information related to the actual planned operation of a crossover mechanism. Standard incinerator design provides for the utilization of bypass stacks which permit the discharge of uncontrolled emissions upon the failure of an APC system. The crossover theoretically would shift the discharge from one incinerator's failed APC system to the second incinerator's APC system, during which time the operation of the second incinerator unit would be reduced or would cease in order to provide adequate capacity in the operating APC system for the discharge from either or both operating incinerators. The application does not provide information related to the operation, design or location of the crossover mechanism. There is no information as to how the facility would address the potential situation where, with only one incinerator and APC system operating, an APC system failure would occur. The utilization of the crossover mechanism is unique, there being no similar medical waste incineration facility crossovers in use elsewhere. It is not possible to determine, given the lack of detail in the application, whether the crossover mechanism could be expected to adequately and successfully address potential "upset" situations. The site plan identifies two buildings on the site, one for incineration operations and the second for ash storage. There is no information supplied related to the location or storage of delivered, but unincinerated, biohazardous wastes, although, if the site plan is accurate, such storage apparently occurs within the incineration building. The application states that solid wastes (ash and lime) will be collected and disposed of off-site in an approved landfill. At hearing, BMS submitted an ash residue management plan, providing the applicant's plan to manage ash from the incinerators and the baghouse discharge. The plan was not signed or sealed by the applicant's professional engineer although he attested to the plan at hearing. According to the plan, incinerator bottom ash generated by the facility "will be handled in a manner which will prevent danger of contamination or release to the environment". Ash will be removed from "the consumat Model CS 1200 incinerator" 4/ unit by means of an ash ejection ram and collected in a wet sump, designed to eliminate dust and blowing ash. The wet ("quenched") ash is removed from the water-filled sump by a drag chain from which excess water will drain for reuse in the ash sump. The wet ash will exit the building by conveyer and be deposited into a covered, metal, "roll-off"-type, water tight storage container. When full, the container contents will be sampled and a representative sample provided to a DER-approved laboratory for Toxicity Characteristic Leaching Procedure ("TCLP") analysis. The container will thereafter be sealed, and the ash trucked to an approved disposal facility. Baghouse waste will include fly ash and reagent waste related to the dry scrubber treatment. Such waste will be removed through a bottom drop hopper discharging into 55 gallon drums. The hopper/drum system will be shielded to prevent waste escape into the atmosphere. Upon filling, the drums will be sampled for the TCLP analysis and then sealed and transported to the approved disposal site. The BMS Ash Residue Management Plan also states: "Type A class waste will be disposed of by Waste Managements, Inc., at their facility located at 3000 N.W. 48th Street, Pompano Beach, Florida 33073. In the event ash residue would not be classified as Type A waste, it will be disposed of by Chemical Waste Management, Inc., whose offices are also located at 3000 N.W. 48th Street, Pompano Beach, Florida 33073." The Ash Residue Management Plan is insufficient to comply with the DER's requirement related to such plans. The plan fails to indicate the capacity of the disposal site or whether the disposal site is intended to receive ash residue from the solid waste combustor for the life of the facility. The plan is ambiguous as to whether the identified sites are actual disposal sites or are offices of the company which will allegedly handle disposition of the ash. The plan fails to address the beneficial uses, if any, of ash residue, although the plan does state that ash recycling is not anticipated. The plan fails to identify contractual requirements, or notification and inspection procedures, which assure that hazardous wastes are not received or burned in the facility. Although the plan states that the incinerator ash will be placed into a wet sump to eliminate dust and blowing ash, and that wet sump water will be recycled into the sump, the plan fails to address the cumulative effects such water reuse and the potential impact of exposure to humans or the environment. As to the baghouse hopper/drum system (shielded to prevent waste escape into the atmosphere) the plan fails to consider other pathways of human or environmental exposure such as through direct contact or ingestion, and the potential for soil and ground water contamination. The application states that any liquids generated from wash-downs and cleaning operations will be collected in a holding tank and thereafter incinerated. The application contains no design or engineering data which identifies the means for incinerating such liquids or establishes that such liquid incineration will be accomplished in a manner which will not adversely affect incinerator or APC operation. Petitioners assert that the facility is experimental in nature because the design is rudimentary and the crossover mechanism is not used in medical waste incinerators of this type. Respondents assert that the facility is not experimental, and that the various types of equipment proposed are in use at other incineration facilities elsewhere. The evidence fails to establish that the entire facility should be properly identified as "experimental", however, there is no credible test data available for a facility utilizing this proposed combination of equipment in the configuration identified in the application. It is likely to expect a biohazardous waste incinerator to emit multiple air pollutants. Such pollutants include particulate matter and hydrogen chloride (HCI), as well as toxic pollutants such as arsenic, cadmium, chromium, lead, mercury, manganese, nickel, zinc, and dioxin equivalents. As to toxic pollutants, the DER reviewed the anticipated chemical emissions of arsenic, mercury, manganese, cadmium, chromium VI, nickel, zinc, lead, tetrachlorodibenzo dioxin (TCDD), and hydrochloric acid. The draft permit in this case requires the proposed facility to conduct emissions tests for particulate matter, hydrogen chloride, oxygen and carbon monoxide within 60 days of initially operating the facility, and to conduct annual emissions tests thereafter. At hearing, the applicant agreed to monitor emissions for the toxic pollutants arsenic, cadmium, chromium, lead, mercury, manganese, nickel, zinc, and dioxin equivalents, and further agreed to continuously monitor carbon monoxide and opacity. The DER has established a policy related to the control of toxic emissions from an air pollution source. The "Air Toxics Policy" is an effort by the DER to protect public health from the potential dangers posed by inhalation of excessive levels of toxic air emissions. The DER has a working list of 756 chemicals for which acceptable emission levels have been established. In identifying chemicals for inclusion on the working list, the DER utilized sources which referenced chemicals of concern and also reviewed data related to the air toxics programs of other regulatory agencies. The DER air toxics working list suggests acceptable ambient air concentration levels for the identified toxic chemicals. The acceptable levels are identified as "no threat levels" or "NTL's" and are set forth at average eight hour, 24 hour, and annual concentration levels. The DER asserts that the NTL's are conservative figures and that adverse public health consequences are unlikely to occur when ambient concentration emission levels do not exceed the NTL's. In establishing the average eight and 24 hour concentration NTL's, the DER utilized the more conservative of figures available from either the federal Occupational Safety and Health Administration (OSHA) or the American Conference of Governmental Industrial Hygienists (ACGIH). The OSHA and ACGIH figures are applicable to exposure of a healthy employee to a single chemical for an eight hour working period. The annual NTL's are directly based on EPA health data values listed in the EPA's Integrated Risk Information System. Of the three NTL's, the EPA- based annual levels are considered to be more accurate. In situations where the eight and/or 24 hour averages are exceeded, additional consideration is given to whether the annual NTL is also exceeded. The DER has not reviewed the data upon which the EPA, OSHA and ACGIH levels rely, and has not independently reviewed the statistical methodology utilized by the EPA, OSHA and ACGIH in calculating the cited agencies acceptable emissions levels. However, the weight of the testimony in support of the methodology, absent specific evidence to the contrary, establishes that such reliance is reasonable. In attempting to establish eight and 24 hour NTL's for use in the DER's Air Toxics Policy, the DER considered the likelihood that air emissions would contain multiple toxic chemicals and would impact a less healthy population (including particularly susceptible individuals) for an extended period of time. The DER reduced the eight hour OSHA/ACGIH concentration by two orders of magnitude, resulting in DER eight hour NTL's which are 100 times less than the OSHA/ACGIH levels. The DER further reduced the 24 hour OSHA/ACGIH levels by a factor of 4.2 (based upon dividing the total hours in a seven day period by a 40 hour work week) resulting in DER average 24 hour NTL's which are 420 times less than the OSHA/ACGIH acceptable occupational levels. Petitioners assert that the uniform safety factors calculated by the DER which resulted in the reduction of OSHA/ACGIH figures to the DER NTL's are arbitrary, and that some NTL's were likely too high and others were too low. However, Petitioners did not identify any of the 756 chemical NTL's on the DER working list as inadequate or excessive. The greater weight of the evidence establishes that the DER's utilization of a two magnitude safety factor is appropriate. Based upon the lack of adverse health impacts on the working population subject to OSHA/ACGIH occupational levels, the dearth of toxicological data available for most substances of concern, and absent evidence to the contrary, the inclusion of safety factors which result in an average eight hour NTL 100 times less than the OSHA/ACGIH levels and an average 24 hour NTL 420 times less than the OSHA/ACGIH levels is a reasonable attempt to prohibit excessive emissions and protect the general public's health from dangers posed through inhalation of such toxic air emissions. The DER annual average air toxic concentration levels are directly derived from EPA data and are distinguished on the basis of whether or not a substance is a carcinogen. For carcinogens, the NTL is based upon a unit risk factor which equates to a one in one million increased risk of developing a cancer related to said chemical. For non-carcinogens, the DER NTL is based upon an "inhalation reference concentration" which relies directly upon inhalation toxicity data, where such data is available. Where "inhalation reference concentration" data is unavailable, the DER NTL is based upon an extrapolation of oral toxicity data. The evidence fails to establish that the reliance of the DER on such EPA data is inappropriate or unreasonable. The DER utilizes the air toxics working list to compare anticipated emissions from a proposed air pollution source to the NTL's. Not all 756 chemical comparisons are made in every case. The comparison is for the purpose of determining whether additional inquiry should be made related to specific chemical emissions. The instant application includes predicted emission rates supplied by engineer Baker. The Baker estimates are based upon actual uncontrolled incinerator emission test results, to which a predicted "control efficiency" was applied for each type of control technology proposed in the application. The control efficiency predictions were based upon a noncommercial Canadian pilot project utilizing a dry-scrubber/baghouse combination, on non peer-reviewed literature and, as to mercury emissions, on a telephone conversation with a representative of the municipal waste industry. At the hearing, Petitioners utilized a data base compiled by Dr. Paul Chrostowsky, who supplied emissions estimates based upon his data base. The data base consists of actual test results from incinerators (including 12 medical waste incinerators) and from peer-reviewed literature. None of the facilities in the Chrostowsky data base reflect data from facilities utilizing a dry scrubber/baghouse system. Half of the incinerators in his data base utilized no controls, one utilized a baghouse, and the remaining five utilized wet scrubbers. Dr. Chrostowsky took the average emissions levels and added one standard deviation to account for uncertainty related to the lack of an operating record for the proposed facility. The emissions estimates produced by Dr. Chrostowsky are deemed to be more reliable and are credited. Dr. Chrostowsky opined that the applicant's estimates did not reflect likely operating conditions and were unreasonably low. According to his estimates, the application underestimated emission rates for hydrogen chloride, arsenic, cadmium, lead, manganese, mercury, and nickel. He also opined that the application's predicted mercury removal rate of 94% was excessive and that a removal rate 70% would be more likely. However, even given Dr. Chrostowsky's emissions levels, only the 24 hour NTL for hydrogen chloride is exceeded. Although Dr. Chrostowsky's calculated an exceedance of the annual average HCI NTL, the calculation was based on error. Other emissions remain at levels below the DER's level of acceptable emissions established by rule. Utilization of a 70% mercury removal rate still results in mercury emissions within the DER's range of acceptable emissions. As to Dr. Chrostowsky's estimated hydrogen chloride emission in excess of the DER's 24 hour NTL, such calculation appears to have been based on the application's estimated HCI control efficiency of 90%. The application utilized a conservative figure based upon the DER minimum requirement of 90% HCI control, when the actual HCI control efficiency could likely be greater than 90%. However, given the preliminary state of design and the lack of test results and data reflective of this particular equipment configuration, the evidence is insufficient to determine with reasonable assurance that such requirement will be met, or that the 24 hour HCI NTL will not be exceeded. It should be noted that the DER's NTL's address only potential human impact through inhalation, on the assumption that the most likely human ingestion for air emissions is through inhalation. The policy does not address human consumption of toxics though contaminated water supplies or via other pathways, Given the proximity of the proposed facility to local water supplies, the potential for other ingestion impacts exists, and should be examined. The application also included the results from engineer Baker's air dispersion modeling, performed to predict local concentrations of certain pollutants in the ambient air. The results indicate that maximum one, eight, and 24 hour concentrations will occur approximately 100 meters from the stack, and that maximum annual average maximum concentrations will occur approximately 500 meters from the stack. Mr. Baker first utilized a standard screening model developed by the federal Environmental Protection Agency specifically for this purpose. Mr. Baker is not an expert in computer modeling and utilizes standard EPA programs to perform such functions. If an initial comparison demonstrates that expected emissions from a proposed pollution source exceed an NTL, additional review of anticipated emissions is conducted to determine whether the initial review data is inaccurate or, if not, whether additional APC technology is required to control the excess emission. The use of an initial screening model is standard scientific practice and is reasonable. Mr. Baker uses the screen model to determine whether there are exceedances of any relevant emissions standards. Where no exceedances occur, it is generally unnecessary to perform further modeling. The Baker screen model relied upon hypothetical meteorological data unrelated to the meteorological variables at the proposed incineration facility site. The screen model results are regarded as an estimation of maximum one hour air pollutant concentrations at or beyond a property line. A set of conversion factors is applied to the maximum one hour air pollutant concentration with the results predicting eight hour, 24 hour, and annual concentrations. According to Mr. Baker's screen model results, the proposed facility's emissions did not exceed the DER's air quality standards or the NTL's in the working list. Mr. Baker subsequently utilized a more advanced EPA model, identified as the "Industrial Source Complex" (ISC) model, which projects both short-term and long-term concentrations. Mr. Baker opined that the ISC model provides a more accurate estimation of pollutant dispersion into the atmosphere. In running the model, he relied upon National Weather Service (NWS) surface meteorological data from Fort Myers and on NWS upper air meteorological data from Tampa, (as the DER had directed) and upon default EPA options. The NWS data included five years of weather information. Based on the ISC model, Mr. Baker anticipates that the emissions will not exceed the DER's air quality standards or NTL's. Meteorological conditions in LaBelle may differ significantly from the NWS Tampa upper air meteorological data. Tampa is much closer to the Gulf of Mexico than LaBelle. Lake Okeechobee, located nearby to the east of LaBelle, may impact LaBelle's local conditions. There is no reliable LaBelle meteorological data easily available, and the DER did not require collection of such site-specific data. Although an expert witness opined that, based upon Orlando's inland location, available Orlando NWS upper air data would be more representative of LaBelle conditions than the Tampa data used, the witness utilized the Tampa data to run his models. There is no actual evidence that utilization of Orlando data would have resulted in different pollutant dispersion modeling results than those included in the application. On behalf of the Petitioners, the ISC model was run utilizing the same weather data used by Mr. Baker and the emissions projections calculated by Dr. Chrostowsky, resulting in substantial agreement between the modeling results. Petitioners suggest that the applicant should have been required to provide data related to the dispersion of air pollutants during certain specific meteorological events, such as temperature inversions. Such inversions occur when warm upper air traps the cooler air below, and holds air pollutants close to the Earth's surface. Although the evidence related to such inversions is based upon a one-year frequency of fog incidence for Ft. Myers, Tampa and Orlando (rather than an analysis of temperature and air pressure data) temperature inversions may occur in LaBelle as often as 20 or more times annually. Utilization of a five year set of NWS data would include occurrences of temperature inversions. Fumigation concentrations occur when, during the dissipation of temperature inversions, the cooler and warmer air levels mix, and pollutants concentrations at the top of the cooler air level may be pulled down resulting in short, but intense, concentrations of pollutants at ground level. It is likely that fumigation events occur in the LaBelle area. Stagnation events are similar to fumigation events, although apparently affecting a larger geographic area than does a fumigation event. It is likely than stagnation events occur in the LaBelle area, however, there is no model which simulates a stagnation event. The screen model utilized in this case by the DER does simulate a fumigation event. According to the screen model predictions, maximum pollutant concentrations would occur under neutral stability conditions, not during fumigation events. The DER utilized the ISC model to predict small particle deposition ("fallout"). Fallout is specific to the meteorology of a site. The ISC model does not accurately predict fallout and such modeling is not required by the DER's regulations. However, such information, if available, could provide useful particle deposition data, given the proximity of the site to the City of LaBelle public water supply. Petitioners assert that the DER should have required a full risk assessment to determine the facility's potential for adversely affecting the local environment and residents in the area. A limited assessment, solely related to dioxin risks and acid gas risks, was performed on behalf of the Petitioners. The evidence is insufficient to establish whether or not the proposed incineration facility will result in an adverse health risk to the general population residing in the area, but given the location of the proposed facility and proximity to the local water supply and to sensitive receptors, the completion of a full risk analysis is warranted. As to dioxin levels, the limited risk assessment estimated that the BMS facility would produce a cancer risk ten to 100 times greater than the risk associated with Lee County's proposed nonbiohazardous waste incineration facility. However, the predicted dioxin emission levels are within the range established by the EPA as acceptable. The Petitioner's expert further opined that such EPA figures overestimate the cancer potency of dioxin. An acid gas analysis was performed utilizing the "hazard quotient/hazard index" method of analysis. The hazard quotient/hazard index analysis provides an acceptable approach to determining air emission health risks. Acid gases include hydrogen chloride, sulfur dioxide, nitrogen oxides, hydrogen fluoride, and sulfuric acid mists. Certain meteorological conditions, including temperature inversions or fog, interact with acid gases to form acid mists and other agents injurious to human lung function. The acid gases/acid mists risk assessment indicates that the incineration facility increases the potential for hazardous health impacts on the local population.
Recommendation Based on the foregoing, it is hereby RECOMMENDED that the Department of Environmental Regulation enter a Final Order denying the application of Bio-Med Services, Inc., for a permit to construct a biohazardous waste incineration facility at the LaBelle Industrial Park, in LaBelle, Florida. DONE and RECOMMENDED this 31st day of March, 1992, in Tallahassee, Florida. WILLIAM F. QUATTLEBAUM Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 31st day of March, 1992.
Findings Of Fact Bay County's application to construct a sanitary landfill comprising nearly 80 acres located at the north end of Bay County abutting Washington County near the intersection of S.R. 20 and S.R. 77 was initially submitted to the Department of Environmental Regulation (DER) in November, 1979 (Exhibit 1). The site is surrounded by 400 feet of pine woods which buffer the site from all roads and residences . There are no residences within several hundred yards of the proposed site and the nearest natural body of water is over one-fourth mile from the site. The noise generated by the operation of the landfill will be similar to the noise generated on S.R. 20 and S.R. 77 by passing vehicles. Following conferences between representatives of Bay County and DER and several revisions of the application of May 16, 1980 DER issued its notice of intent to grant the applied-for permit (Exhibit 10) and this proceeding was initiated by Petitioners. The site is located in an area of predominately "Lakeland series" sands which provides little barrier to the percolation of surface or ground waters into the Floridan Aquifer. The site is one of the highest in Bay County and the ground water table is located about 45 feet below the surface in this area. The Floridan aquifer lies some 100 feet below the proposed site and is in direct contract with the ground water table. Accordingly, contamination of the ground water by the proposed landfill would enter into the Floridan Aquifer and degrade the water quality of this aquifer. Additionally escaping leachate could contaminate and degrade the waters of the lakes in the general vicinity of the proposed site. As initially presented the application was denied by DER and recommended for denial by the other state agencies involved, viz. Florida Game and Freshwater Fish Commission and the Northwest Florida Water Management District. The reason for disapproval was that, absent some impervious surface between the aquifer and lakes in the vicinity could occur and was likely. Not only is the site located in a recharge area to the Floridan Aquifer but also in a karst area, in which the topography is marked by sinkholes resulting from the collapse of cavernous limestone under the ground. While the possibility exists that a sinkhole could develop under the proposed landfill this is no more likely than that a sinkhole will develop anywhere else in the northern half of Bay County. As finally proposed the site will be developed into cells some 400' x 500' x 28' deep which are expected to be filled in about six months, covered with a a clayey soil and vegetation replanted over the cell. To keep leachate from escaping to the lakes or aquifer the cells will be lined with a polyvinyl chloride (PVC) liner is 20 mils thick manufactured by B. F. Goodrich. If the liner functions as proposed there will be no escape of leachate and hence no degradation of the waters. Petitioners contend that reasonable assurances have not been given that the PVC liner will adequately perform this function and this was the only real issue presented at the hearing. PVC liners for landfills have been in use for only bout 10 years. However, numerous tests have been conducted and, projecting the deterioration of the PVC observed during the test period to the estimated life of the landfill, leads to an expected liner life well beyond the life of leachate production in the landfill. To give PVC the flexibility and elasticity necessary to lay it over uneven surfaces in sheets, plasticizers are added to the PVC during the manufacturing process. These plasticizers will be released from the PVC if exposed to sunlight for an extended period. However, as proposed for use here, even if the liner was exposed to sunlight for the entire six months the cell will be open, or even for one year, no significant loss of plasticizer will result. Once the cell has been closed, no further dynamic stresses will be placed on the liner. Accordingly, even if the liner lost all of its plasticizer and thereby lost its elasticity and flexibility, it would remain impervious and prevent the pasage of leachate through the liner. To protect the liner from solid waste, trash, and equipment used in the cell to compress the solid waste, the liner will be covered with two feet of sand before any solid waste is placed in the cell. Each night the solid waste dumped that day will be covered with six inches of on-site earth material to deter flies, odors, etc. The two feet of sand cover will protect the liner from puncture by solid waste or equipment. The liner will be placed on a tight slope with a sump provided near the low end of each cell from whence leachate will be pumped from the cell and treated, if necessary. Additionally, vents will be installed to exhaust gases from the cell once it is closed. Monitoring wells will be placed around the land fill to detect if leachate is escaping from the site. These wells would allow detection of escaping leachate before it could progress to the natural water bodies in the general vicinity. The three to one slope proposed for the sides of the landfill will result in some movement of free sand resting on the liner along the sides and could bare the liner. To insure there will be a minimum of two feet of soil between the fill material and the liner the cell will not be filled completely to the side of the liner to fill in the space left between the garbage and the side wall each day when the material dumped that day is covered. Hazardous wastes will not be allowed at the site. The site will be enclosed and have an attendant on duty at all times it is opened to receive solid waste. Public access will be restricted and the attendant on duty will monitor the waste dumped in the cell. Household wastes will be accepted and these may include small quantities of paints, insecticides and other material that in large quantities would be considered hazardous. The sand over the liner, the pumping out of the leachate and overall operation of the landfill are adequate to protect against these small amounts of hazardous materials. Bay County proposes to use an existing disposal site to dump tree and hedge trimmings and may provide a place to dump this woody trash at the proposed site other than in the cells. This will increase the capacity of the cells for solid waste and diminish the possibility of damage to the liner by woody products. The only credible evidence submitted regarding the availability of alternate sited for the proposed landfill was that other areas further south were investigated and were unacceptable because the groundwater table was above the bottom of the proposed cells. This would result in dumping solid waster directly into the water table, and is unaceptable. Petitioner's principal contention is that there has been insufficient experience with PVC liners and the tests that have been conducted were not sufficiently rigorous or extensive to provide assurances that leachate would no escape from the site and contaminate the waters of the State. Petitioners also contend that joining of sections of PVC in field, which will be necessary to cover that bottom of the cells (because a liner large enough to cover the bottom of one cell would be too large and heavy to handle), would also create unacceptable risks in the making of these "field seams". Bay County has arranged for the manufacturer of the PVC to provide personnel to supervise the "field seaming" of the sections of the PVC. These seams do not need to be wrinkle-free and no particular problem with respect to joining sections of PVC liner so as to make it watertight was shown. The tests conducted by the Environmental Protection Agency on PVC liners have been ongoing for nearly ten years. None of these tests to date show any reason to question the effectiveness of a PVC liner properly installed to provide an impermeable barrier to leachate in a sanitary landfill. Petitioners also object to the use of cover material proposed by Bay County when a cell is closed. The soil analysis submitted with the application for the cover proposed does not have a high clay content and is more permeable than would be desired. At the hearing, Bay County officials testified they would use a more impermeable soil to cover the cells. Failure to do so would increase the amount of water from rainfall that would penetrate the cell, thereby increasing the quantity of leachate to be pumped from the sump. This would increase the maintenance cost of the landfill to the point it would be uneconomical not to put a water-repellant cover on the cell when it is closed. No evidence was presented that the formation of additional leachate would increase the risk of leachate escaping from the cell.
Conclusions Having considered the Recommended Order, including the Findings of Fact and Conclusions of Law, Petitioners' Exceptions, and Respondent's Response to Petitioners' Exceptions, it is, therefore: ORDERED that the Hearing Officer's Findings of Fact are adopted; his Conclusions of Law and Recommended Order, to the extent that they are consistent with this Final Order, are adopted; and ORDERED that the permit reflected in the Notice of Intent issued by the Department on May 16, 1980, be issued with the following additional conditions: The applicant shall notify the Department at least on week in advance of when the P.V.C. is to be installed and allow for on-site inspection of its installation by Department personnel. No operation permit will be issued unless the applicant has shown reasonable assurances that the P.V.C. has been properly installed and all other applicable rules of the Department and the applicable Florida Statutes have been complied with. Any operation permit issued shall be for only one cell and no permit for subsequent cells shall be approved in accordance with 2. above without a showing of proper operation for the previous cells. The final cover material for each cell shall be clay, substantially clay or other impermeable material. Any DER permits for this site shall only be valid until 24 months from the date of this order. ORDERED that the country shall submit within thirty days a plan with schedule by which this landfill site will be phased out in 24 months, which shall include selection of alternate acceptable sites or the implementation of a resource recovery program in accordance with 17-7, Part II, Florida Administrative Code.

Findings Of Fact The proposed site consists of some 311 acres bounded on the South by Alligator Alley (SR 84) and is approximately 6 1/2 miles East of SR 858. The existing solid waste disposal facility at the airport is exceeding the capacity of the area to absorb any additional solid waste. An approved federal grant for expansion and improvement of the Naples airport is contingent upon the cessation of further solid waste disposal at this site. The original deadline for discontinuing use of the airport disposal site of June 30, 1975 has been extended to allow the processing of the instant application. Of the numerous sites considered the one proposed herein was considered by local, state, and federal agencies to be the best overall. The proposed site meets the requirements of, and has been approved by the USDA Soil Conservation Service, the Department of Environmental Regulations, and various state health organization. The plans and specifications which have been submitted by the county and approved by the various agencies concerned called for an excavation of the site to a depth of approximately 3 feet, with the solid waste after compaction being placed in the ground and each layer thereafter placed on top and covered on a daily basis with soil. A perimeter canal will be constructed around the site to divert surface water from outside the site to prevent flooding the area. Interior canals will be installed to provide for collection of the leachate, as well as water falling on the site. The project includes construction of leachate sump ponds on the site, which will be coated to preclude the leachate from percolating into the surrounding area. An all weather access road will be provided to the site, and the only vehicles permitted on the site will be those controlled by the county and city, which would include their contractor for hauling waste. The routes for these vehicles would be such that they would not pass' over the Golden Gate Boulevard, which goes through the community of Golden Gate. At the hearing little new evidence was submitted. Intervenor appeared to take the position that its opposition to the project was based upon the fact that: (1) The site proposed could flood; (2) An impermeable barrier should be installed in all cells to preclude harmful materials from permeating the soil; and (3) Leachate from the cells could enter into the ground water table. Testimony with respect to these objections revealed: (1) The pumping system proposed is adequate to handle any flooding that may reasonably be anticipated; (2) The site is not located on a watershed that could go to a public water supply; (3) The site is some 5 or 6 miles from the nearest public water supply and not so located that surface water from the site could flow to a public water supply; (4) No place in Collier County meets the 5 foot separation provision between water table and place where waste could be dumped; The safeguards provided by the proposed plan qualifies this site for waiver of provision (4) above; (5) If an impermeable barrier was installed beneath the cells it would be ineffective in preventing surface water contamination in the event the site is flooded; (6) In the event the proposed system proves inadequate to control flooding, modifications in the then existing system could be made that would control this problem; and (7) Use of impermeable barrier below cells is but one design method to meet requirements of the various regulatory agencies.
Findings Of Fact On April 29, 1983, the Respondent Waste Aides Systems, Inc. (hereafter referred to as Waste Aides), filed with the Department of Environmental Regulation (Hereafter referred to as DER) an application to construct and operate a solid waste transfer station. The proposed transfer station would be located at the site of an existing solid waste landfill at Ridge Road and Landfill Road, New Port Richey, Florida. On May 24, 1983, DER, by letter to Waste Aides, requested additional information concerning the permit application and seeking further assurances with regard to control of wash down water and storm water runoff. On June 7, 1993, Waste Aides, by letter provided the additional information, and on June 14, 1983, DEP issued a letter of intent to issue the permit to Waste Aides. The proposed facility is to be located on a parcel of land previously used as a solid waste landfill, but the area where the facility is to be built is not a previously filled solid waste area. The proposed facility will utilize a building which is enclosed on the south, east, and west, and open to the north. The building will be approximately 120 feet wide, 48 feet deep, and 31 to 34 feet high. The general operation of the facility will be to transfer residential and commercial solid waste from garbage trucks to large tractor-trailer trucks for transport to a more isolated solid waste landfill. The facility will not accept hazardous waste or heavy industrial waste. The solid waste will be transported to the facility in garbage trucks. The solid waste will be dumped on a concrete floor inside the building and will then be pushed into a loading chute which sits directly above a waiting trailer. Once the trailer is filled, the solid waste is then transported to an offsite landfill where it is ultimately disposed of. Security at the facility will be accomplished through fencing and gates. The entire property is surrounded by a fence. A gate will be placed at Ridge Road, and a second gate will be installed at the entrance to the property itself. No unauthorized vehicles will be permitted to enter the property or unload solid waste at the facility. The facility will be equipped with two fire control hoses located on the east and west walls of the building. Potable water will be provided to the facility through a hookup to a 16-inch water main at Ridge Road. The facility will have impact sprinklers and spray bars inside the loading chute. Each vehicle on site will be equipped with a fire extinguisher, and two portable fir extinguishers will be located inside the building at appropriate locations. The impact sprinklers will also be utilized for dust control. Each vehicle on site will be equipped with a two-way radio which provides contact with the administrative office and maintenance area of the applicant. The phone in the cardboard recycling facility located on the same property of the proposed facility will be available for use by the operator of other employees of the transfer facility. The recycling facility is owned and operated by the applicant and is directly adjacent to the proposed transfer facility. The operator will be responsible for keeping records of materials handled by the facility. A recordation of volume will be measured and entered as collection trucks discharge their contents at the facility. A scale will be built into the loading area of the transfer trailers, and the weight of all refuse transferred will be recorded by load on a daily basis. These records will be open during normal business hours for inspection by DER representatives, health inspectors, and other authorized regulatory and enforcement agencies. The transfer station operator will be the foreman of the facility and will be present during all hours of operation. The tractor-trailer operator and the operators of the garbage trucks will be present at the facility during unloading and loading. Two or three other employees will also be present on the grounds at varying times for cleanup, grounds work, and other duties at the facility. The facility will be visited and checked approximately twice daily by William R. Peterson and his brother, the owners and operators of the proposed facility. The applicant has available personnel presently in the employment of the applicant, who is a certified driving instructor and who is skilled in the instruction of safe and efficient operating procedures. Additionally, Waste Aides will provide instructions in first-Aides procedures by a person presently employed who is a trained emergency medical technician. Debris will be controlled by certain mechanisms built into the design of the building and by certain operational procedures that will be observed by the transfer station operator. The tipping floor where solid waste is discharged will be enclosed on three sides. When the solid waste is discharged onto the tipping floor, it is immediately pushed into a chute which allows it to fall into the waiting transfer trailer. There is approximately an 8-inch tolerance between the chute and the top of the trailer, and the chute has been designed to angle in toward the trailer so that solid waste will be directed into the trailer to avoid spillage. Additionally, a rubber or fabric membrane will encircle the chute so that when the transfer trailer drives beneath it, the membrane will be inside the transfer trailer, thus directing all solid waste into the trailer itself. An additional benefit of this design is that it will avoid the possibility of drafts of air blowing refuse in the trailer over its sides. The trailer area itself is depressed and thus out of the direct wind stream. Drafts are further buffered by vegetation windbreaks consisting of trees and shrubs located on the west and south sides of the building and by the topographical nature of the surrounding lands on the other two sides. The entire area of the transfer station is fenced as a final barrier to debris escaping the transfer station site. The refuse will normally be on the tipping floor a very short period of time because of the fact that it will be pushed into the transfer trailer immediately upon discharged from the collection vehicle. The refuse, as it is discharged from the collection vehicle, does not lend itself to a debris problem in that it is in a compressed state and tends to remain in a semifragmented mass until it is moved into the trailer. The entire transfer station and surrounding grounds will be cleaned at the end of each day by the station operator. The station will be operated at all times to be in compliance with the applicable noise regulation and ordinances of Pasco County. For noise abatement, Waste Aides has designed the building with noise control in mind. The tipping floor will be constructed with steel rails imbedded in the concrete to eliminate the noise of the front-loading metal bucket scraping on the concrete surface. Six-foot walls buffet all sides of the tipping floor except the north side. The north side is open to an approximate 10-acre tract which was the previous landfill site and will be unoccupied. The tipping floor is enclosed by a building which will provide a significant amount of noise control in a and of itself. There are vegetation screening barriers and earthen berms on the north, west, and south boundaries of the site. The berms will be covered with mature vegetation and will act a both a noise and visual barrier for the site. All equipment used in the operation will meet all county, state, and federal operational decible standards. Odor control will be provided primarily by operational standards which will emphasize the rapid removal of refuse from the site. All refuse will be removed daily except for the possibility of partially filled trailers remaining overnight on site. Should a transfer trailer be required to remain on the site overnight, it will be driven inside the building not less than every 48 hours or in accordance with an approved DER schedule. The tipping floor will be completely cleaned at the end of each workday by being swept broom-clean and then washed down with hoses. When the floor is washed down, the water and debris will flow along the sloped floor to a grid system which will direct the flow into a sand trap and a grease trap and then into a septic tank. The traps will be checked each day after wash down and will be cleaned periodically. The building has been designed in such a manner that no square corner will exist for the possible buildup of refuse. These same operational procedures and design features will discourage any attraction to vermin or birds. Similar transfer station operations in Florida have not experienced the vermin and odor problems typically associated with landfill site operations. The prosed facility will have electric service available. Shelter as well as hand-washing and toilet facilities are available for employees for the facility at the adjacent recycling building. Maintenance on trucks and other equipment will be performed at the applicant's maintenance area located on Osteen Road, approximately 1 to 1 1/2 miles from the proposed facility. Although the proposed facility is surrounded by developed residential areas, the property which is directly contiguous to the property where the proposed facility will be located remains undeveloped. The objectors' travel- trailer park is the closest developed area, and the distance from the nearest trailer to the proposed facility is approximately 950 feet. The design and proposed operation of the transfer station meets or exceeds the criteria contained in Rule 17-7.09, Florida Adminstative Code. Numerous residents in the area object to the location of a garbage transfer station. Their objections are based upon their experience with odor, vermin, birds, and litter experienced in connection with the landfill operation. However, the uncontradicted evidence established that those problems will not exist to any substantial degree in connection with the operation of the proposed garbage transfer station.
Recommendation Based upon the foregoing findings of fact and conclusions of law, it is RECOMMENDED That the Department of Environmental Regulation issue a permit to Waste Aides Systems, Inc., for the construction and operation of the proposed transfer station, subject to the specific conditions contained in DER's Notice of Intent.

The Issue The issue in these consolidated cases is whether the agency should grant variances from Rule 10D-6, F.A.C. regarding construction of on-site sewage disposal systems on the lots in question.
Findings Of Fact Jerry Gagliardi is the developer and engineer for an 8-lot subdivision on Merritt Island, Brevard County, Florida. Mr. Gagliardi is a self-employed civil and mechanical engineer. The small subdivision has a long, narrow configuration, extending west to east. It is bounded on the north by an existing drainage ditch and a large tract of undisturbed wetlands. Its south boundary is a finger canal, and its east boundary is Pelican Creek. With the exception of the wetlands, most of the property in the area is already developed. There are no residences built yet on the eight lots. Hook-up to an existing sanitary sewer system is available within one- quarter mile of the subdivision. The entire area, with several finger canals, is served by the sanitary sewer system. Mr. Gagliardi planned to install on-site disposal systems (septic tanks) in the subdivision. When his plan was rejected he applied for variances for lots 1 and 2 in July 1992, stating economic hardship as the basis for the request. The applications were reviewed by Gregory D. Wright, Supervisor for Brevard County Consumer Health Services and his staff. Several site visits were made and a site evaluation was completed. Mr. Wright recommended denial of the variance because the sanitary sewer system is available; the soils (mostly sand and shell) are unsuitable for on- site disposal systems; and the area, virtually surrounded by water, is environmentally very sensitive. Mr. Wright is also concerned that a variance for the two lots will establish a precedent for variances on the remaining lots in the subdivision. Mr. Wright also observed that there is an existing irrigation well on a neighboring lot within thirty feet of the proposed septic tank on lot #1. This well does not appear on Mr. Gagliardi's plans. The Department of Health and Rehabilitative Services Review Group for Individual Sewage Disposal concurred with the local agency's recommendation after consideration of Mr. Gagliardi's hardship argument. The request was not considered to be a minor deviation from the minimum requirements of the law and regulations. For approximately three years Jerry Gagliardi has been providing information on his development plans to the local county staff. He has become extremely frustrated with the process. However, he has still failed to produce the evidence which he must have to justify the variances he is seeking. At the hearing, Mr. Gagliardi claimed that hook-up to the existing sanitary sewer system is impossible because there is insufficient elevation for gravity feed and there is not enough room on Banana River Drive for another sewer line easement. He did not submit evidence to support that claim and it is unclear whether he has made that claim to the local staff for their verification. He has consistently claimed that hook-up to the existing system is prohibitively expensive. He has estimated that the cost of installing hook-up to the existing system would be $52,642 for the entire subdivision, or $6580.25 per lot. He has estimated that installation of aerobic on-site septic systems would cost $28,000.00 or $3500 per lot. This estimate does not include the cost of culverting the ditch along the north boundary of the property. The culvert may be necessary to meet the water body set-back requirements and, assuming that a permit would be granted for its construction, the culvert would substantially increase the cost of the septic tank project. As recently as three weeks prior to hearing, Mr. Gagliardi provided information to the staff that the value of the lots in the subdivision is $60,000.00 each, for lots #1 through #6; and $115,000.00 and $120,000.00, for lots #7 and #8, respectively. At hearing he repudiated that information as being based on three year old appraisals. He now asserts that the value of the lots is closer to $40,000.00 each. Petitioner's exhibit #2 is a cover letter dated January 4, 1993, to Mr. Gagliardi from the Brevard County Property Appraiser. Attached to the letter are four property management print-outs reflecting the value of two lots as $35,000.00, and two others as $65,000.00. The record does not reflect which lots those are in the subdivision and there is no explanation for the inflated values provided to the staff after the printouts were received. It is impossible from the confused and conflicting evidence provided at hearing to determine that the petitioners are entitled to a variance.
Recommendation Based on the foregoing, it is hereby RECOMMENDED: that the agency enter its final orders denying Petitioners applications for variances.

Findings Of Fact The Parties The Department is the state agency with the power and duty under chapter 403, Florida Statutes, to review and take action on applications for permits to construct and operate solid waste management facilities, including landfills. Angelo's is a Florida limited partnership authorized to conduct business under the name Angelo's Recycled Materials. Angelo's filed the permit applications which are the subject of this proceeding. Angelo's owns the property on which the proposed landfill would be constructed and operated. Crystal Springs Preserve is a Florida corporation that owns approximately 525 acres in Pasco County, Florida on which is located Crystal Springs, a second magnitude spring that flows into the Hillsborough River. The property is about 10 miles south of Angelo's proposed landfill site. Crystal Springs Preserve's primary business activities are selling spring water for bottling for human consumption and operating an environmental education center that focuses on Crystal Springs and the Hillsborough River. Crystal Springs Preserve hosts approximately 50,000 visitors annually at the environmental education center. Crystal Springs Preserve holds a water use permit which authorizes it to withdraw up to 756,893 gallons of water per day (annual average) from Crystal Springs for production of bottled water. The water is transported about three miles to a water bottling facility operated by Nestlé. Nestlé is a private corporation engaged in the business of bottling and selling spring water. Nestlé purchases spring water from Crystal Springs Preserve. Nestlé's "Zephyrhills Spring Water" brand is composed of approximately 90 percent Crystal Springs water and 10 percent Madison Blue Spring water. The only water treatment applied by Nestlé is filtering the water to remove gross contaminants and passing the water through ultraviolet light or ozone to kill any potential bacteria before bottling. Nestlé has established "norms" for its spring water and would not be able to use the water from Crystal Springs if its chemical composition varied significantly from the norms. WRB is a Florida corporation that owns 1,866 acres in Pasco County known as Boarshead Ranch. Boarshead Ranch is adjacent to the east and south of Angelo’s property and is approximately 3,000 feet from the proposed landfill at its closest point. Boarshead Ranch is currently being used for agricultural, recreational, residential, and conservation purposes, including wildlife management. Nearly all of Boarshead Ranch is subject to a conservation easement held by the Southwest Florida Water Management District (SWFWMD). The conservation easement allows WRB to continue agricultural operations. Numerous agricultural water wells are located on Boarshead Ranch. WRB holds a water use permit which authorizes the withdrawal of 820,000 gallons per day (gpd) (annual average) for a number of uses, including production of agricultural products, animal drinking water, and personal use. The City of Zephyrhills is located in Pasco County and is a municipal corporation. Zephyrhills' water service area encompasses Zephyrhills and portions of Pasco County. Zephyrhills owns, operates, and maintains a water distribution and transmission system of pipes, pump stations, and storage tanks within the City and its service area. Zephyrhills holds a water use permit which authorizes nine potable water supply wells with a combined withdrawal of 2.9 million gallons per day ("mgd") (annual average). Zephyrhills has two new production wells located about two miles southeast of the proposed landfill. The City of Tampa owns and operates the David L. Tippin Water Treatment Plant, the Hillsborough River dam, and the City of Tampa reservoir on the Hillsborough River. Flows from Crystal Springs make up a substantial amount of the water in the Hillsborough River, especially during drought conditions when the spring flow accounts for about 50 percent of the flow. The City of Tampa holds a water use permit which authorizes the withdrawal 82 mgd (annual average). The City of Tampa owns, operates, and maintains a water distribution and transmission system of pipes, pump stations, and storage tanks within the City and its service area. Carl Roth, Marvin Hall, and Louis Potenziano own property in Pasco County near the proposed landfill site. Roth's property is 3.5 miles west of the proposed landfill site; Hall's property is located approximately one mile southwest of the site; and Potenziano's property is 1.6 miles to the south/southeast of the site. Roth, Hall, and Potenziano have water wells on their properties. The record does not establish that John Floyd owns property in the area. Floyd and Associates, Inc., owns about 55 acres in the area and holds a water use permit authorizing the withdrawal of water for agricultural uses. The Stipulated Agreement On March 1, 2010, Angelo's filed with DOAH a "Stipulated Agreement" signed by all parties. The Stipulated Agreement states in relevant part: Angelo's shall provide a final design, revised complete permit application and site investigation (referred to jointly as "Revised Submittal") to DEP with copies to all Parties and DEP shall make a completeness determination prior to this proceeding being set for a new final hearing date. * * * Angelo's shall not revise its permit application or supporting information beyond the Revised Submittal prior to or during the final hearing except in response to issues raised by DEP. It appears that the Aligned Parties did not remember the Stipulated Agreement until the commencement of the final hearing. They did not object before then to any of the evidence which Angelo's had prepared or intended to prepare for hearing on the basis that it violated the terms of the Stipulated Agreement. At the commencement of the hearing, Nestlé argued that the Stipulated Agreement barred Angelo's from revising its application or presenting new support for its project at the final hearing. The Stipulated Agreement is unusual and the necessity for Angelo's to make any concessions to the Aligned Parties in order to obtain their agreement to an abeyance was not explained. Allowing an applicant time to amend a permit application is usually good cause for an abeyance. The Stipulated Agreement allowed Angelo's to continue to respond to issues raised by the Department. Angelo's contends that all of the evidence it presented at the final hearing qualifies as a response to issues raised by the Department. The Proposed Landfill Angelo's applied to construct and operate a Class I landfill with associated buildings and leachate holding tanks. Application No. 22913-001-SC/01 corresponds to the construction permit application and Application No. 22913-001-SO/01 corresponds to the operation permit application. A Class I landfill is a landfill authorized to receive Class I waste, which is solid waste from households and businesses. Class I waste does not include hazardous waste, yard waste, or construction and demolition debris. See Fla. Admin. Code R. 62-701.200(13) and (14). The proposed landfill would be approximately 30 acres in size. It is part of a 1,020-acre parcel owned by Angelo's that is west of County Road 35 and south of Enterprise Road in Pasco County. The site is currently leased for cattle grazing and hay and sod production. There are also spray fields, orange groves, and a pond on the 1,020-acre parcel. Angelo's would construct the landfill by first clearing the 30-acre site. It would then excavate and fill to create the design subgrade or floor of the landfill with slopes required for the liner system. The subgrade would be compacted with a vibratory roller. After the subgrade compaction, the grouting plan would be implemented. The grouting plan calls for grouting 39 subsurface locations on the site that have voids, loose soils, or other unstable characteristics. A liner system would be installed after the grouting is completed and the subgrade is finished. From the bottom upward, the liner system would begin with a 12-inch layer of clay, over which a reinforcement geotextile would be installed, followed by another 12-inch layer of clay. This reinforcement geotextile is in addition to the double liner system required by Department rule. Its purpose is to maintain the integrity of the liner system in the event that a sinkhole occurs beneath the landfill. Installed above the reinforcement geotextile and clay layer would be a 60-millimeter high-density polyethylene ("HDPE") geomembrane, followed by a HDPE drainage net. These last two components comprise the secondary leachate collection system. Above the HDPE drainage net would be the primary leachate collection system, consisting of another 60-millimeter HDPE geomembrane and HDPE drainage net, followed by a geotextile, then a 12-inch sand layer for drainage, and an additional 12-inch sand layer for protection against puncture of the HDPE liner. A 48-inch layer of selected waste, free of items that could puncture the liner, would be the first waste placed over the primary leachate collection system. "Leachate" is "liquid that has passed through or merged from solid waste and may contain soluble, suspended, or miscible materials." See Fla. Admin. Code R. 62-701.200(66). Leachate would be collected through a system of perforated pipes that empty into a sloping trench with a leachate collection pipe. The leachate collection pipe would run down the center of the landfill to the lowest point where a pump would send the collected leachate through a force main 0.25 miles to storage tanks. Five above-ground storage tanks would be installed on a concrete pad with capacity to store 90,000 gallons of leachate. The stored leachate would be periodically transported to an offsite location, such as a wastewater treatment facility, for disposal. Sinkholes and Karst The terms "sinkhole" and "sinkhole activity" are not defined by Department rule, but the statutory definitions in chapter 627, a chapter dealing with insurance coverage for homes and other buildings, are generally consistent with the scientific meanings of these terms. The term "sinkhole" is defined in section 627.706(2)(h) as: a landform created by subsidence of soil, sediment, or rock as underlying strata are dissolved by groundwater. A sinkhole forms by collapse into subterranean voids created by dissolution of limestone or dolostone or by subsidence as these strata are dissolved. The term "sinkhole activity" is defined in section 627.706(2)(i) as: settlement or systematic weakening of the earth supporting the covered building only if the settlement or systematic weakening results from contemporaneous movement or raveling of soils, sediments, or rock materials into subterranean voids created by the effect of water on a limestone or similar rock formation. Sinkholes occur throughout Florida. There have been many reported and confirmed sinkholes in Pasco County. The more common type of sinkhole that has occurred on the Brooksville Ridge is a "cover subsidence" sinkhole, which is caused by voids in the limestone and the downward movement--"raveling"--of overlying soils into the cavity. Eventually, the loss of soils in the raveling zone will propagate upward until the soils at the ground surface also move downward and a depression is formed at the surface. Cover subsidence sinkholes develop slowly and are usually small, less than ten feet in diameter. Less common are "cover collapse" sinkholes, which can form in a matter of days or hours as the result of the collapse of the "roof" of a dissolved cavity in the limestone. These sinkholes are usually large and deep. The occurrence of a sinkhole does not always mean that areas near the sinkhole are unstable. However, the occurrence of a sinkhole is reasonable cause for concern about the stability of nearby areas and a reasonable basis for the Department to require thorough geologic investigations. "Karst" refers to limestone that is undergoing dissolution and it is common in Florida. A sinkhole forms in karst. "Epikarst" is limestone that was weathered while exposed above sea level millions of years ago before being submerged again. It is generally softer and more permeable than unweathered limestone. "Paleokarst" refers to karst that is very old in geologic time. Paleosinks are old sinkhole features in the paleokarst. A paleosink may no longer be unstable because it has been filled in for thousands or millions of years. A "lineament," or a "photolineament," is a relatively straight line seen in the topography or aerial photographs of the ground surface in an area. It might be defined by soil color, sloughs, ponds, wetlands, or other land features that follow a linear path. Lineaments are sometimes, but not always, associated with subsurface fractures in the bedrock where one would expect to also find active karst, sinkholes, and relatively rapid groundwater flow. Even where there is no lineament, there can be fractures in limestone that, when extensive enough, will allow for "fractured," "preferential," or "conduit flow" of groundwater. Fractured flow can occur in a small area or may go on for miles. Springs in Florida are usually associated with fractured flow or conduit flow that allows groundwater to move through the aquifer a long distance relatively rapidly, in weeks rather than decades. Geotechnical Investigation The Department's rules require subsurface conditions to be explored and described, including soil stratigraphy, soft ground, lineaments, and unstable areas, but the rules do not require the application of any particular geologic testing technique. An applicant's testing program is primarily a function of the professional judgment of the applicant’s geologist in cooperation with Department staff. The amount of geological testing done by Angelo's during its initial testing was similar to what was done for recent landfill applications. Angelo's conducted additional testing to respond to Department concerns and to prepare for the final hearing in this case, making the total amount of testing at Angelo's proposed site more extensive than is usual for a proposed landfill. The geologic investigation conducted by Angelo's experts to determine subsurface features, including any sinkholes, employed several technologies. Split Spoon Penetrometer Test (SPT) or SPT borings were drilled with a drill rig that advances a split spoon sampler into the ground with a 140 pound hammer. The hammer is dropped 30 inches and the number of blows required to drive the sampler each successive 12 inches is referred to as the "N" value and indicates soil strength and density. The higher the N value, the denser the soil. When the material is so dense the drill rod cannot (essentially) be hammered deeper, the N value is shown as "R," which stands for "refusal." SPT Bore logs also note any observed "weight of hammer," "weight of rod," or "loss of circulation." These terms describe areas where the drilling encounters very soft material or voids. Weight of rod, for example, means the weight of the drilling rod, by itself, with no hammer blow, was enough to cause the rod to fall deeper through the soil or rock. Cone Penetrometer Test ("CPT") borings were also conducted. CPT borings are relatively shallow, performed with a hand-held rod and special tip that the operator pushes into the ground. The CPT equipment continuously measures and records tip resistance and sleeve resistance as the rod moves downward through soils. It is helpful in some applications, but is less precise in determining soil type, strength, and compressibility than SPT borings and cannot be used to explore deep zones. Ground penetrating radar ("GPR") studies were used. GPR equipment transmits pulses of radio frequency waves into the ground. The manner in which the radio waves are reflected indicates the types of soil and rock encountered. It can also detect cavities and other features that would suggest karst activity. When the GPR identifies geologic features of interest, they can be further investigated with SPT borings. Another investigative tool used by Angelo's was Multiple Electrode Resistivity ("MER"). MER uses a grid of wires and electrodes and the equipment interprets the resistivity of electrical signals transmitted through the subsurface. MER data can be displayed in a two dimensional or three dimensional format, depending on the software program that is used to process the data. Like GPR, MER is useful for indentifying geologic features of interest that can be further explored with SPT borings. However, GPR generally has good resolution only near the ground surface, while MER has good resolution to a depth of 100 feet. The Regional Geology The proposed site is in a geologic transition zone on the eastern flank of a regional, geological feature known as the Brooksville Ridge. It is a transition zone for both the Suwannee Limestone and Hawthorn Group. The Brooksville Ridge was formed when it was part of the coastline. In its geologic past, the Brooksville Ridge experienced sea level changes, weathering, erosion of sediments, and beach reworking. The general layering of geologic features on the Brooksville Ridge, from the top down, begins with topsoil and a layer of sand. Under the sand layer is the Hawthorn Group, an older geologic layer consisting of a heterogeneous mix of limestone, clays, and sands which generally range in depth from slightly under 60 feet to 80 feet or more. It was formed by river and wind erosion, flushing, and re-deposition in a beach dune environment. Below the Hawthorn Group is the Suwannee Limestone Formation, which is present throughout eastern Pasco County. The upper surface of the Suwannee Limestone Formation is undulating, due to a gradual chemical weathering of its upper surface, representing a "paleokarst environment." Underlying the Suwannee Limestone Formation is the Ocala Limestone Formation. It extends throughout most of Florida. It is composed of nearly pure limestone and is considered the Floridan Aquifer. It extends across the site’s subsurface. Angelo's used the Florida Geologic Survey's data base to determine there are six sinkholes within five miles of the proposed landfill. A seventh sinkhole, not in the data base, is the 15- foot sinkhole at the Angelo's Enterprise Road Facility landfill, a Class III landfill (yard waste and construction and demolition debris) about a mile northwest of the proposed site. Angelo's contends that the sinkhole at its Class III landfill was "induced" during construction of the facility by the diversion of stormwater runoff to an area where overburden had been removed. The average diameter of the seven sinkholes is 11.9 feet. The Geology of the Proposed Site Rule 62-701.410(2)(c) requires a geotechnical site investigation and report, which shall: Explore and describe subsurface conditions including soil stratigraphy and ground water table conditions; Explore and address the presence of muck, previously filled areas, soft ground, lineaments, and sinkholes; Evaluate and address fault areas, seismic impact zones, and unstable areas as described in 40 C.F.R. 258.13, 258.14 and 258.15; Include estimates of the average and maximum high ground water table across the site; and Include a foundation analysis to determine the ability of the foundation to support the loads and stresses imposed by the landfill. It may include geotechnical measures necessary to modify the foundation to accommodate the imposed loads and stresses. The foundation shall be analyzed for short-term, end of construction, and long-term stability and settlement conditions. Considering the existing or proposed subgrade conditions and the landfill geometry, analysis shall include: Foundation bearing capacity; Subgrade settlements, both total and differential; and Subgrade slope stability. Angelo's conducted a geotechnical site investigation, but it was not adequate, as discussed below and in sections I. and J. The proposed landfill site is geologically complex, having features that are discontinuous horizontally and vertically. The site has karst features or areas where the limestone has dissolved. There is a clay layer in some areas, but it is not continuous and its depth and thickness vary. There are deposits of hard and soft sands at various depths. There are pinnacles of limestone surrounded by softer materials. Photographs from a quarry called the Vulcan Mine, located on the western flank of the Brooksville Ridge, show exposed features in the top 20 to 30 feet of the Suwannee Limestone in the region. The features at the Vulcan Mine are roughly similar to features at the Angelo's site. There are a number of shallow depressions on the surface of the ground on the Angelo's site. The origin and significance of these depressions was a matter of dispute. The Aligned Parties believe they represent sinkhole activity, but the evidence presented did not rise to the level of proof. However, Angelo's did not prove they were unassociated with geotechnical issues that could affect the proposed landfill. Angelo's offered no reasonable explanation for the depressions. Determining the exact cause of the depressions may not be possible even with more extensive investigation, but it was Angelo's responsibility as the permit applicant, pursuant to rule 62-701.410(2)(c), to make a greater effort to account for them. Angelo's initial permit application identified two intersecting lineaments on Angelo's property, based on aligned lowlands, enclosed valleys, and ponds. Angelo's contends the lineaments do not reflect an unstable subsurface or fractured limestone. The Aligned Parties contend that the lineaments are regional features and reflect fractures in the bedrock. They also contend that the onsite pond, which is located along the lineament, is an old sinkhole. The Aligned Parties did not prove the proposed landfill site is above an area of fractured bedrock, but the evidence presented by Angelo's was incomplete and insufficient to show there are no fractures. The limestone on the site was not adequately investigated for voids and fractures. Angelo's did not refute the possibility that the lineaments reflect a significant subsurface feature that could affect both site stability and groundwater movement. The Regional and Local Hydrogeology Rule 62-701.410(1) requires a hydrogeological investigation and site report, which shall: Define the landfill site geology and hydrology and its relationship to the local and regional hydrogeologic patterns including: Direction and rate of ground water and surface water flow, including seasonal variations; Background quality of ground water and surface water; Any on site hydraulic connections between aquifers; For all confining layers, semi-confining layers, and all aquifers below the landfill site that may be affected by the landfill, the porosity or effective porosity, horizontal and vertical permeabilities, and the depth to and lithology of the layers and aquifers; and Topography, soil types and characteristics, and surface water drainage systems of the site and surrounding the site. Include an inventory of all the public and private water wells within a one-mile radius of the proposed landfill site. The inventory shall include, where available: The approximate elevation of the top of the well casing and the depth of each well; The name of the owner, the age and usage of each well, and the estimated daily pumpage; and The stratigraphic unit screened, well construction technique, and static water levels of each well. Identify and locate any existing contaminated areas on the landfill site. Include a map showing the locations of all potable wells within 500 feet of the waste storage and disposal areas to demonstrate compliance with paragraph 62- 701.300(2)(b), F.A.C. Angelo's conducted a hydrogeological investigation, but it was not adequate, as discussed below. Angelo's and the Aligned Parties disputed the hydrogeological characteristics of the proposed landfill site and region. The principal disputes related to the direction and velocity of groundwater flow. Angelo's contends that groundwater flows from the landfill site to the west, making the proposed landfill site part of the Withlacoochee River groundwater basin. The Aligned Parties contend that groundwater flows south toward Crystal Springs and, therefore, the site is within the "springshed" of Crystal Springs. A United States Geological Survey map of the Crystal Springs springshed shows Angelo's proposed landfill site within the springshed. A springshed study done for SWFWMD also indicates the site is within the Crystal Springs springshed, but the District has not always been consistent in its statements about the groundwater basin boundaries in this area. A water chemistry analysis of the groundwater in the area of Angelo's proposed landfill indicates that the site is an area of higher recharge and within the Crystal Springs springshed. The springshed boundary can shift, depending on rainfall. Angelo's hydrogeological evidence was not sufficient to refute the reasonable possibility that the proposed landfill site is within the Crystal Springs springshed. Therefore, the Department's determination whether Angelo's has provided reasonable assurances must account for the threat of contamination to Crystal Springs and the other public and private water supply sources to the south. There are no creeks or streams and only a few lakes in the area between Crystal Springs and the Angelo's site. The absence of surface runoff features indicates it is an area of high recharge to the groundwater. Crystal Springs is in an area of conduit flow. The hydrologic investigation conducted by Angelo's was not thorough enough to characterize surficial aquifer flow and flow between aquifers. The preponderance of the evidence shows more groundwater recharge to the Floridan Aquifer in the area than estimated by Angelo's. Angelo's hydrogeological investigation was inadequate to refute the possibility of fractured flow or rapid groundwater movement at the proposed landfill site. Angelo's contends there is a continuous clay confining layer that would prevent contamination from moving into deep zones, but the preponderance of the evidence shows discontinuity in the clay and large variations in thickness and depth. The landfill's impermeable liner will impede water movement downward from the landfill, but groundwater will still recharge from outside the landfill to carry any contaminants deeper. If fractured flow or conduit flow extends south from the proposed landfill site, any leachate released into the groundwater beneath the landfill could travel rapidly toward the water supply sources of the City of Zephyrhills, Crystal Springs, Nestlé, and the City of Tampa. Whether the Proposed Landfill is in an Unstable Area Rule 62-701.200(2)(a) prohibits the storage or disposal of solid waste "[i]n an area where geological formations or other subsurface features will not provide support for the solid waste." However, the Department has adopted by reference a federal regulation, 40 C.F.R. 258.15, which allows a landfill to be constructed in a geologically unstable area if the permit applicant can demonstrate that engineering measures are incorporated into the design to ensure that the integrity of the landfill’s structural components "will not be disrupted." The parties presented evidence on many disputed issues of fact at the final hearing, but most of the case involved two ultimate questions: whether the proposed landfill site is unstable and, if so, whether Angelo's has proposed measures that would eliminate the unstable conditions and make the site suitable for a landfill. as: An "unstable area" is defined in 40 C.F.R. § 258.15 A location that is susceptible to natural or human-induced events or forces capable of impairing the integrity of some or all of the landfill structural components responsible for preventing releases from a landfill. Unstable areas can include poor foundation conditions, areas susceptible to mass movements, and Karst terrains. There is overwhelming evidence that the proposed landfill site is an unstable area. A considerable amount of evidence presented by Angelo's supports this finding. For example, Angelo's experts agreed there are loose soils, evidence of raveling, and sinkhole activity. These conditions make the site susceptible to natural or human-induced events or forces capable of impairing the integrity of some or all of the landfill structural components responsible for preventing releases from the proposed landfill. The Department's landfill permitting staff requested a sinkhole risk assessment from the Florida Geologic Survey ("FGS"). The State Geologist and Director of the FGS, Dr. Jonathan Arthur, believes the potential for sinkhole formation at the proposed site is moderately high to high. That potential is consistent with the characterization of the area as unstable. Whether the Proposed Engineering Measures Are Adequate Because the site is unstable, Angelo’s must demonstrate that engineering measures have been incorporated into the landfill's design to ensure that the integrity of its structural components will not be disrupted. See 40 C.F.R. § 258.15(a). The engineering measures proposed by Angelo's are discussed below. Because it was found that Angelo's hydrogeological and geotechnical investigations were not sufficient to characterize all potentially unstable features of the subsurface, it was not demonstrated that the proposed engineering measures would overcome the instability and make the site suitable for a landfill. Roller Compaction Angelo's would use roller compaction on the graded floor of the landfill to compact the soils to a depth of about five feet and eliminate any voids within that depth. The Aligned Parties did not contradict Angelo's evidence that its proposed roller compaction will be done in a manner exceeding what the Department usually requires as far as roller force and the number of roller "passes." However, roller compaction will not affect deep voids. Liner System In order to ensure that the landfill’s liner system components will not be disrupted in the event of a sinkhole, Angelo’s proposes to include the reinforcement geotextile discussed above. The Department previously approved the use of geotextile reinforcement, combined with grouting, to demonstrate site stability for the Hernando County Northwest Landfill, which had a comparable risk of sinkhole formation according to the Department. The reinforcement geotextile can span a 15-foot diameter sinkhole without failure. As found above, the average diameter of the seven sinkholes within five miles of the proposed landfill is 11.9 feet. Angelo's proved that the proposed liner system meets all applicable criteria, except the requirement of rule 62- 701.400(3)(a) that the liner be installed upon a geologically stable base. Grouting Plan Angelo's grouting plan would be implemented to fill voids and stabilize areas of loose or weak material. The grouting plan was first designed to grout all locations where there was a Weight of Hammer, Weight of Rod, Loss of Circulation, or loose sands, as indicated by a low blow count. Angelo's revised the grout plan to include several more areas of concern identified later, for a total of 39 locations. Each grout location would have seven grout points, one in the center and six others equally-spaced on a ten-foot radius from the center. If more than ten cubic yards of grout is needed, additional grout points further outward would be injected until the void or loose soils are filled or stabilized. Although Angelo's proposes to grout every boring of concern, that still ties the integrity of the grouting plan to the thoroughness of the borings. The geologic evidence indicates that there are unstable areas which the grouting plan does not address. The Aligned Parties' MER analysis was persuasive in identifying potential areas of instability that were omitted from Angelo's investigation and from its grouting plan. There are other unstable areas existing on the site that should be grouted or otherwise engineered to provide support for the landfill. The grouting plan does not provide reasonable assurance that the integrity of the structural components of the landfill will not be disturbed. Other Issues Raised by the Aligned Parties The Aligned Parties raise a number of other issues, some of which begin with the assumption that the site is unstable and a large sinkhole would form at the landfill. This sometimes mixes issues inappropriately. It has been found that Angelo's did not provide reasonable assurance that the site will support the proposed landfill, but other project elements must be reviewed on their own merits where possible, assuming the site was engineered for stability. Leachate Collection System There is a single leachate collection trench in the center of the two landfill cells, which makes the landfill operate much like a single cell. The two halves of the cell slope toward the center, so that leachate will drain to the leachate collection trench, and the entire landfill slopes to the west, so that the trench will drain to a sump from which the leachate is pumped to storage tanks. At full capacity, the landfill will generate about 40,000 gallons of leachate per day. Careful cutting and grading of the earth is necessary to create the slopes that are essential to the proper functioning of the project’s leachate collection system. Settlement analyses are necessary to assure that the slopes are maintained. Rule 62-701.410(2)(e) requires a foundation analysis which must include a study of "subgrade settlements, both total and differential." "Total settlement" refers to the overall settlement of a landfill after construction and the loading of solid waste. "Differential settlement" compares settlement at two different points. Angelo's did not meet its burden to provide reasonable assurance on this point. The settlement analysis conducted by Angelo's was amended two or three times during the course of the final hearing to account for computational errors and other issues raised by the Aligned Parties. The analysis never came completely into focus. The final analysis was not signed and sealed by a professional engineer. The settlement analysis is dependent on the geologic analysis, which is inadequate. Without adequate settlement and geologic analyses, it cannot be determined that leachate collection would meet applicable criteria. Storage Tanks The Aligned Parties contend that the leachate storage tanks cannot be supported by the site. Because it was found that Angelo's geologic investigation was not adequate to identify all unstable areas, it is also found that Angelo's failed to provide reasonable assurance that the site would support the leachate storage tanks. In all other respects, the Aligned Parties failed to refute Angelo's demonstration that the storage tanks would meet applicable criteria. Groundwater Monitoring Plan The Aligned Parties contend that there is an insufficient number of monitor wells proposed by Angelo's to detect a leak from the landfill and the wells are too shallow. Because it was found that Angelo's did not adequately characterize the geology and hydrology of the proposed landfill site, the monitoring plan does not provide reasonable assurance of compliance with applicable criteria. Cell Design The Aligned Parties contend that the "mega-cell" design proposed by Angelo's provides less flexibility to respond to and isolate landfill problems than other landfill designs with smaller cells, and the mega-cell design could generate more leakage. No evidence was presented to show whether Angelo's design was one that had been approved or rejected in the past by the Department. Although it is not the best landfill design, the Aligned Parties did not show that the proposed design violates any permitting criteria. Operation and Closure The evidence presented by the Aligned Parties in support of their issues regarding the operation of the proposed landfill, such as noise, odor, and traffic, was not sufficient to refute Angelo's evidence of compliance with applicable criteria, with one exception: Angelo's has not provided an adequate contingency plan to show how it would respond to a sinkhole or other incident that required the landfill to be shut down and repaired. Assuming the site was engineered to support the landfill, there is nothing about the Closure Plan that the Aligned Parties showed does not meet applicable criteria.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Protection deny Angelo's Permit Application Nos. 22913-001-SC/01 and 22913- 002-SO/01.

The Issue Whether the Petitioner's request for variance should be granted.
Findings Of Fact Petitioner owns an undeveloped parcel of land in Palm Beach, County which is zoned industrial and on which he intends to construct a storage building to house and repair farm equipment. To provide sewage treatment at the site, Petitioner had designed an on site sewage disposal system and applied for a septic tank permit which was denied as was his variance request. The closest public sewage treatment plant to the property is over five miles from the site, and the closest private treatment is approximately three miles from the subject site. Petitioner has no easement to either site if capacity were available and if he chose to connect. However, the proof did not show capacity at either site. Although Petitioner does not intend to pollute the groundwater, the proof demonstrated that waste disposal into a septic tank from the maintenance and repair of farm equipment could result in the disposition of prohibited hazardous waste into the groundwater. Alternative methods of waste disposal are available which would properly dispose of the waste and, yet, protect the groundwater from contamination by hazardous waste. Such systems include certain aerobic treatment units and package plants. The monetary costs of these systems is greater than the septic tank proposal; however, the proof did not demonstrate that the cost was prohibitive or a hardship. Although the hardship, if any, caused by the denial of the variance was not caused by Petitioner, the proof failed to demonstrate lack of reasonable alternatives of waste disposal and the absence of adverse effect of the operation to the groundwater. Additionally, the proof failed to establish the ameliorating conditions of soil, water table or setback conditions although a survey of the property dated September 3, 1985, indicates that the subject parcel was not platted. Accordingly, the denial of the variance was proper.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that a final order be entered denying the variance. DONE AND ENTERED in Tallahassee, Leon County, Florida, this 6th day of July 1989. JANE C. HAYMAN 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 6th day of July 1989.

The Issue The issue is whether Respondents should have an administrative penalty imposed, take corrective action, and pay investigative costs for allegedly maintaining a solid waste management facility without a permit and disposing of solid waste in an area subject to periodic or frequent flooding.
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: Background DDD is a corporation registered to do business in the State of Florida. Its president and sole director is William H. Stanton, Jr. The corporation is engaged in the business of "mobil recycling activities" (reduction recycling services for customers). Mr. Stanton owns a two-acre tract of property located in Section 26, Township 28S, Range 24B, on the northwest corner of Mustang Road and Longhorn Drive, Lakeland, Florida. The property is zoned for heavy industrial uses and was formerly used in some form of phosphate mining operations. The Department is the agency charged with the duty of administering and enforcing the provisions of Chapter 403, Florida Statutes, and rules promulgated thereunder. Based upon a complaint made by a Polk County Health Department employee, on October 8, 2001, a Department enforcement coordinator, Steven G. Morgan, inspected Mr. Stanton's property and observed that Respondents had filled and compacted an approximate 150 foot by 300 foot area of the site with 3 to 5 feet of "wallboard type material," which consisted of "both ground up and large pieces of wallboard." In the middle of the filled area was an additional pile of the same material around 20 to 25 feet high. Petitioner's Exhibits A, D, and E are photographs which provide an accurate representation of the site on the date of the inspection. Based on a visual inspection, but without having the benefit of his own laboratory analysis,2 Mr. Morgan concluded that the material was a solid waste made up of discarded industrial products. Under Department rules, the deposit of solid waste on such a site requires a waste facility management permit from the Department. A check of Department records indicated that Respondents do not hold a permit to operate a solid waste management facility. (DDD does hold a valid air pollution permit for grinding concrete.) During his inspection, Mr. Morgan also observed that the land adjacent to the filled area was wet, had a lower elevation than the compacted area, and contained small pockets of standing water. This was confirmed by photographs received in evidence as Petitioner's Exhibits D and E. A DDD employee who was present on the site during the inspection indicated that approximately 900 truck loads of the material had been transported to the site from Plant City after Mr. Stanton had "lost" a lease on the property on which the material had previously been placed. This was confirmed by Mr. Stanton who arrived at the site shortly after the inspection began, and who indicated that he intended to use the compacted wallboard as a sub-base (or foundation) for a wallboard recycling facility. A second site inspection by Mr. Morgan conducted on February 5, 2002, confirmed that the conditions (regarding the piles of fill material but not the standing water) at the site were unchanged from those found on October 8, 2001. On that visit, Mr. Morgan observed the site from his automobile but did not walk the property. Two other site visits were made, one on June 19, 2002, by other Department personnel. Except for a photograph (Petitioner's Exhibit C) dated June 19, 2002, which indicates the piles of material were still intact and had not been removed, the results of those inspections are not of record. Shortly after the initial inspection, the Department's Tampa District Office issued a warning letter to Mr. Stanton describing Mr. Morgan's observations and outlining the potential violations. The letter also invited Mr. Stanton to resolve the matter informally and to present a corrective action plan to mitigate the site. When the matter could not be resolved informally, the Department issued its Notice on October 10, 2002, alleging that Respondents had operated a solid waste facility without a permit and had deposited solid waste in an area prone to flooding. Even though the matter was not informally resolved, Mr. Stanton has cooperated with the Department in good faith throughout the regulatory process. The Material on the Site Invoices received in evidence reflect that the source of the deposited material was James Hardie Building Products in Plant City, Florida, and that the material was described on the invoices as "Dry Waste Material," Wet Waste Material," and "Foreign Material." James Hardie Building Products manufactures HardieBoard, which is a one-half to one-inch thick concrete formulated product used in the construction of homes and other buildings, and HardiePipe, which is used in road and bridge construction, culverts, storm sewers, and concrete pipes. The material being deposited was material used in the manufacture of HardieBoard. Mr. Stanton's long-range plans are to grind up, or recycle, the material (after all necessary permits, if any, are obtained) and then sell it to other persons, including cement manufacturing plants in the area, who will then use it for a variety of purposes, including subbase and base material, cement and concrete re-additive, and cement production. HardieBoard (as well as HardiePipe) is a variable mixture of Portland cement, water, fine silica sand, less than 10 percent cellulose (a non-toxic organic material commonly added to such products as ice cream, shampoo, baby diapers, and rayon clothing), and less than 10 percent of inert materials. The cellulose fibers are added to the concrete to avoid cracking and shrinkage and to reduce the weight of the product. Unlike concrete used for driveways and the like, HardiBoard does not have any large aggregate. Disposal of Solid Waste and Clean Debris Florida Administrative Code Rule 62-701.300(1)(a) prohibits the storing, processing, or disposing of solid waste except at a permitted solid waste management facility. In addition, no solid waste may be stored or disposed of "[i]n an area subject to frequent and periodic flooding unless flood protection measures are in place[,]" or "[i]n any natural or artificial body of water including ground water." Fla. Admin. Code R. 62-701.300(2)(d) and (e). These requirements form the basis for the charges in the Notice. Florida Administrative Code Rule 62-701.200(113) defines solid waste in relevant part as "discarded material, including solid, liquid, semi-solid, or contained gaseous material resulting from domestic, industrial, commercial, mining, agricultural, or governmental operations." Section 403.707(2)(f), Florida Statutes (2003), provides, however, that a permit is not required for "[t]he use of clean debris as fill material in any area." See also Fla. Admin. Code R. 62-701.220(2)(f). "Clean debris" is defined in Florida Administrative Code Rule 62-701.200(15) as: any solid waste which is virtually inert, which is not a pollution threat to ground water or surface waters, is not a fire hazard, and is likely to retain its physical and chemical structure under expected conditions of disposal or use. The term includes brick, glass, ceramics, and uncontaminated concrete including embedded pipe or steel. The term "virtually inert" is not defined by statute or rule. However, the parties agree that in order for a material to be "virtually inert," it must have no potential for leaking contaminants into the groundwater. In addition, if a deposited material releases contaminants into the groundwater thereby posing a threat to human health, it is considered a "threat to [groundwater]" within the meaning of the rule. The rule also provides that the material must not be a fire hazard. Finally, if a material decomposes over time after being used as fill, and releases contaminants into the groundwater, it is not "likely to retain its physical and chemical structure under expected conditions of disposal or use." Therefore, if a material has no potential for leaking contaminants into the groundwater, is not a threat to groundwater, is not a fire hazard, and is not likely to decompose over time, it constitutes clean debris and is exempt from the waste management facility permitting requirements. As noted above, Florida Administrative Code Rule 62- 701.200(15) identifies four materials that are considered to be clean debris: brick, glass, ceramics, and uncontaminated concrete. If a waste product is classified as uncontaminated concrete, it constitutes clean debris and may be used as fill without a permit from the Department. Further, clean debris may be deposited in an area subject to frequent or periodic flooding so long as flood protection measures are taken, or in a natural or artificial body of water so long as other appropriate permits (such as an Environmental Resource Permit) are obtained. Here, the central issue is whether the material deposited on Mr. Stanton's property is solid waste or clean debris. This issue turns on whether the material is virtually inert, is not a pollution threat to groundwater or surface waters, is not a fire hazard, and is likely to retain its physical and chemical structure under expected conditions of disposal or use. Assuming these criteria are satisfied, the material is exempt from Department permitting requirements for solid wastes. On this issue, the Department contends that the material is not virtually inert and is unlikely to retain its physical and chemical structure. Conversely, Respondents assert that the material is clean debris and falls within the category of uncontaminated concrete. Is the Deposited Material Clean Debris? In determining whether a material is virtually inert, or is a pollution threat to ground or surface waters, two extraction procedures have been sanctioned by the United States Environmental Protection Agency to assist in the measurement of the amount of contaminants that will leak from a material: the Toxicity Characteristic Leaching Procedure (TCLP) and the Synthetic Precipitation Leaching Procedure (SPLP). Under both procedures, the material being tested is ground up into small sand-size particles, mixed with an extraction fluid, and tumbled for 18 hours in a rotary agitator while the liquid solution extracts various metals that are found in the solids. The extracted liquid solution is then filtered and analyzed to determine the concentration of metals actually leached from the solids. Under state water drinking standards found in Table 1 of Florida Administrative Code Chapter 62-550, the maximum contaminant levels for chromium and barium (stated in milligrams per liter (mg/L)) are 0.1 mg/L and 2 mg/L, respectively. In reaching its conclusion that the fill material is a solid waste, the Department relied principally on certain tests of the material run by various laboratories between 1998 and 2000, which showed that the amount of chromium and barium leaking out of the product exceeded the State drinking water standards. See Petitioner's Exhibits K, L, M, and O. However, in every one of those tests, the laboratories used the TCLP, rather than the SPLC, which produced a worst case scenario. For the reasons stated below, the TCLP is not the appropriate procedure to be used for this purpose. The TCLP is the more aggressive of the two procedures, uses a much harsher solution than the SPLC, and generally leaches higher concentrations of metals. However, its principal purpose is to determine whether a material should be classified as a hazardous waste based on its leaching properties or characteristics. Using it to predict whether a material will leach into ground water is inappropriate because it will "leach things out in the laboratory that will never leach in the field." This is because it does not mimic conditions in the field and is "just not supposed to be used for this purpose." Therefore, TCLP leachate values should not be applied to drinking water standards. Conversely, the SPLC uses a less harsh solution during the preparation process, evaluates the potential for leaching metals into ground and surface waters, and is designed to provide a more realistic assessment of metal mobility under actual field conditions. In other words, the SPLC simulates what would happen if the sample were exposed to groundwater and rain to determine if under those conditions metals might leach into the water system below. Therefore, the SPLC is the more appropriate procedure to use here to determine whether the HardieBoard material will leach certain metals into the groundwater at levels that exceed State drinking water standards. Even various Department guidance documents provide that the SPLC (rather than the TCLP) should be used to determine if a material will leach metals into the ground water. See Respondents' Exhibits M, N, and O. Respondents' witness Foster collected three samples of HardieBoard deposited by Respondents at another site and submitted them to PPB Environmental Laboratories, Inc., in Gainesville, Florida, for a clinical analysis using the SPLC test. Those results, which have been accepted as being reliable,3 indicate that none of the leachate concentrations for arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver exceed (or even approach) the drinking water standards. Therefore, the material is virtually inert, and the groundwater quality will not be adversely impacted by use of this material as fill. The parties agree that the material is not a fire hazard. Prior to depositing the material, Mr. Stanton used a commercial waste reduction machine (a Smorcazy Bandit Beast 3680 Horizontal Trough Grinder) to grind or pulverize some of the material into fine particles. As noted earlier, a small amount of cellulose fibers are added to the product during the manufacturing process. The Department contends that after the grinding process occurs, these fibers will separate from the remaining fine particles and dissolve into the ground water. Because of this separation, the Department asserts that the material does not retain its physical or chemical structure after being deposited onto the property. Although cellulose fibers are added to the product during its preparation to strengthen the material (and have been added by cement manufacturers since the 1920s), they are distributed throughout the matrix in the material. This means that the fibers become "part and parcel of the mixture" and will not deteriorate, fall out, or leach out of the material even after routine grinding processes, such as that done by Respondents. As such, the cellulose is not biodegradable, and there is no concern that the cellulose will dissolve into the groundwater. Indeed, HardiePipe, which is used in the construction of culverts, storm sewers, and drainage pipes and has essentially the same constituents as HardieBoard, was approved by the Florida Department of Transportation in 2001 for use on State road and bridge projects. Therefore, it is found that the fill material will retain its physical and chemical structure after being deposited onto the ground. Expert testimony by Dr. McClellan established that the material meets the general definition of concrete, and because it is uncontaminated, it should properly be classified as uncontaminated concrete. As such, the material is clean debris and is not subject to the Department's solid waste management permitting requirements. Finally, the Department points out that the compressive strength (measured in pounds per square inch (PSI)) is much greater for concrete used in driveways than for HardiBoard (2500 PSI versus 20 to 30 PSI), and therefore Hardiboard is not a true concrete product. While the PSI values are indeed substantially different, the load bearing ratio or compressive strength of the material does not determine whether a material falls within the generic category of concrete. Water Issues As noted above, if a material is classified as clean debris, it may be deposited into an area prone to flooding or in a natural or artificial body of water, including groundwater (subject, of course, to other unrelated requirements or safeguards). There is no evidence that the filling occurred in a "natural or artificial water body," or directly into the groundwater. In addition, the evidence demonstrates that in October 2001, the ground next to the filled area had small pockets of standing water measuring no more than a few inches deep. However, when the inspection was made, and the photographs taken, Polk County was experiencing rather heavy rainfall, presumably due to the El Nino phenomenon. Whether these conditions (pockets of standing water) exist on the property only during the rainy season is not of record. Further, prior to the filling, Mr. Stanton contacted both the Southwest Florida Water Management District and the United States Geodetic Survey and he asserted, without contradiction, that neither agency indicated that his property was prone to flooding. In any event, even assuming that the area is subject to "frequent and periodic flooding," the permit requirements or other necessary safeguards, if any, associated with filling clean debris in such an area are not the subject of this proceeding. Investigative Costs A Department representative spent 66 hours investigating this matter for the Department. At a then-hourly rate of $18.54, this totals $1,223.64 in investigative costs. The reasonableness of this amount was not disputed by Respondents.
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.
