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.

The Issue The issue to be determined in this proceeding is whether Angelo's Aggregate Materials, LTD ("Angelo's") is entitled to permits from the Department of Environmental Protection ("Department") to construct and operate a Class I landfill in Pasco County.
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 City of Jacksonville has provided reasonable assurances that a proposed modification of its permit to operate the City of Jacksonville North Sanitary Landfill by allowing an additional 35 feet of waste to be disposed of in Phase IIIb of the City of Jacksonville North Sanitary Landfill will not cause pollution in violation of any of the provisions of Chapter 403, Florida Statutes, or the rules promulgated thereunder? Whether the City of Jacksonville proposed modification of its permit to operate the City of Jacksonville North Sanitary Landfill by allowing an additional 35 feet of waste to be disposed of in Phase IIIb of the City of Jacksonville North Sanitary Landfill should be denied because of alleged violations of the City of Jacksonville's permit or Florida law?
Findings Of Fact Introduction. The City of Jacksonville North Sanitary Landfill. The City of Jacksonville (hereinafter referred to as the "City") operates two solid waste disposal facilities. One, the City of Jacksonville North Sanitary Landfill (hereinafter referred to as the "North Landfill"), is located at the intersection of New Berlin Road and Island Drive in the northern part of the City and Duval County, Florida. The North Landfill is operated pursuant to permit #SC16-12205 (hereinafter referred to as the "Permit"), issued by the Department on June 6, 1988. The Permit was issued "for operation of the City of Jacksonville North Sanitary Landfill, Phases I, II, and 111a; and of a new disposal area at the North Sanitary Landfill, Phase IIIb." The area in which the North Landfill is located is generally commercial property, with some rural and residential property: The North Landfill is bounded on the north by unimproved land owned by the City. This property stretches to Cedar Point Road. A few parcels within the property owned by the City to the north of the North Landfill are owned by others, including Mr. and Mrs. Leigh. The property to the east of the North Landfill is also unimproved property. It is owned by the St. Johns River Power Park. The St. Johns River Power Park is a power plant facility operated as a joint venture by the City, the Jacksonville Electric Authority and Florida Power and Light. The plant is located on the southern boundary of the North Landfill. The west boundary of the North Landfill is New Berlin Road. The property to the west of New Berlin Road is owned by a number of persons, including M & M Dairy. Phase IIIb of the North Landfill is located in the northeast quadrant of the landfill. The North Landfill primarily serves northern, and a part of western, Duval County. Approximately 3,000 tons of solid waste is disposed of each day in Jacksonville. Approximately 55% of the solid waste is disposed of at the North Landfill. The solid waste disposed of at the North Landfill consists primarily of mixed municipal solid waste and commercial solid waste. The North Landfill is open seven days a weeks from 5:00 a.m. to 11:00 p.m. All phases of the North Landfill are permitted to a height of 75 feet. The land on which the North Landfill is located is approximately 25 to 30 feet above sea level. Therefore, approximately 45 to 50 feet of solid waste can be disposed of at the North Landfill. All phases of the North Landfill have some remaining capacity for the disposal of additional solid waste. The Petitioners. Ms. Holzendorf's residence is approximately ten miles from the North Landfill. Her office is located approximately seven miles from the North Landfill. She does not own any real property located in the immediate vicinity of the North Landfill. Ms. Holzendorf can smell the odor from the North Landfill at her residence when the wind is blowing from the North Landfill toward her residence. Ms. Holzendorf is a Florida State Representative for District 16. District 16 includes the population of approximately one-third of Duval County, The North Landfill is located within District 16. Ms. Holzendorf has received complaints from some of her constituents about the North Landfill. Ms. Holzendorf drives by the North Landfill approximately twice a week. She has visited the site on several occasions. Robin G. and Geraldine Leigh own real property adjacent to Cedar Point Road. The land is unimproved except for a well. The Leigh's land is located north of the unimproved City property located adjacent to the northern boundary of the North Landfill. The Leighs' land is approximately three-fourths of a mile from the North Landfill. The City's Proposal. On August 3, 1988, the City filed an application with the Department for a modification of its Permit. In its application the City requested a "construction permit modification" of its Permit consisting of "extending the height of Phase IIIb of the North Landfill to a constructed elevation including final cover of no greater than 110 feet, NGVD." The City's requested modification of the Permit will provide the City with an additional six months of solid waste disposal capacity. The Department proposed to grant the City's requested modification. The Department issued a proposed Permit modification (hereinafter referred to as the "Modified Permit"). Structural Design of Phase IIIb. Leachate Control System. Waste dumped at the North Landfill is covered daily. Rain falling on the site is disposed of either as "leachate" or stormwater. Leachate is liquid which passes through, and emerges from, solid waste. Leachate on Phase IIIb of the North Landfill is collected and disposed of by a control system which was designed by George Knecht. Mr. Knecht described the leachate control system as follows: The leachate collection system consists of a two-foot drainage layer placed on top of the plastic liner. In this case the city used a plastic liner rather than a clay liner. It's HDPE, which is high-density polyethylene, and that collects the liquid and lets it flow downhill in this drainage layer to the central point, at which point the city has installed a six-inch perforated pipe which is wrapped in a filter media, which is basically a stone, a rock, which in turn is wrapped in a filter media which is porous cloth, and the purpose is that the liquid coming through the landfill gets into this drainage layer, runs downhill in the drainage layer, goes through the filter cloth, and the filter cloth keeps the sand from penetrating into the granular rock, goes through the rock and into the pipe, and then pipes are laid in a sloping downhill direction so that the fluid, once it gets in there, runs downhill. It's collected in manholes at the end of each one of these pipes. Transcript of Formal Hearing, page 49, lines 4-23. The leachate control system of Phase IIIb was properly installed and designed. Although the Petitioners raised questions concerning the manner in which the leachate control system was installed and designed, they did not offer sufficient evidence to contradict the evidence presented by the City that the system was properly installed and designed. The evidence also failed prove that the addition of 35 feet of solid waste to Phase IIIb will adversely affect the operation of the leachate control system. The addition of 35 feet of solid waste to Phase IIIb will probably ultimately have a beneficial effect on the leachate control system of Phase IIIb of the North Landfill. When Phase IIIb reaches its currently authorized height of 75 feet, the leachate depth on the liner of the control system is expected to be an average of approximately three inches. If an additional 35 feet of waste is added to Phase IIIb, the leachate depth on the liner of the control system is expected to decrease to an average of approximately two inches. The depth of leachate on the liner of the leachate control system of Phase IIIb will not exceed one foot. Specific Condition 3 of the Permit required that the City arrange for Department representatives to inspect the facility in the company of the Permittee, Engineer, and onsite operator after completion of construction activities. Cells I and II of the leachate control system of Phase IIIb were not inspected by the Department. The Department was provided with a certification from a registered professional engineer that the installation was inspected and met state requirements. The Department normally relies upon such certificates. Stormwater Disposal System. Rainwater which does not percolate through the waste, thus becoming leachate, runs off in the form of stormwater. Stormwater will consist primarily of rain which strikes the sides of the pyramid formed by the waste deposited on Phase IIIb of the North Landfill. The existing stormwater disposal system of all phases of the North Landfill consists of a series of ditches which collect stormwater and channel the stormwater to other ditches which surround the perimeter of the North Landfill. Stormwater travels through the ditches to collecting ponds located at the northeast corner of the North Landfill. Water reaching the holding ponds is treated by sunlight, oxidation and sedimentation. Ultimately, water reaching the holding ponds runs into Brown's Creek. The existing stormwater collection system of Phase IIIb is in compliance with the Department's permitting requirements. The proposed increase in height of Phase IIIb should not have any appreciable impact on the quality of stormwater eventually emptied into Brown's Creek. Phase IIIb will be capped with an impermeable cap when it is closed. The City has had a stormwater management system designed to take into account the effect of the cap on stormwater disposal. The stormwater collection system which will be installed when Phase IIIb is closed will consist of ditch blocks which will separate the stormwater collection system of Phase IIIb from the other phases of the North Landfill. Stormwater from Phase IIIb will be directed to a new holding pond. Stormwater will eventually be discharged into Brown's Creek. The stormwater collection system which will be installed when Phase IIIb is closed will meet the requirements of Rule 17-25, Florida Administrative Code, and the St. Johns River Water Management District. The system will actually have a positive impact on water quality. Foundation. The earth beneath the leachate control system of Phase IIIb, because of the weight of the solid waste to be deposited above it, is expected to settle approximately twelve inches under 75 feet of solid waste. The addition of 35 feet of solid waste to Phase IIIb is expected to cause the earth beneath the leachate control system to settle an additional six inches for a total of one and one-half feet. The additional 35 feet of solid waste will not adversely affect the structural integrity or functional capacity of the leachate control system of Phase IIIb. The proposed 35 foot addition of solid waste should not affect the ability of the earth beneath Phase IIIb to support the loads and stress it will be subjected to. III Alleged Violations. Water Quality There is a marsh located to the northeast of the North Landfill. The marsh forms the headwaters of Brown's Creek. Brown's Creek flows into the St. Johns River, south of the North Landfill. Alfred Mintz, the former owner of Clapboard Creek Fish Camp, a fish camp located approximately four miles from the North Landfill, testified about a "black gooey substance" which was on the surface of Clapboard Creek and Brown's Creek. Clapboard Creek flows to the northeast and east of the North Landfill. It eventually flows into the St. Johns River. The substance came from the direction of the North Landfill. Mr. Mintz did not know what the substance was and was unable to identify the source of the substance. The evidence failed to prove what the substance was or that the North Landfill was the source of the substance. Anita James, a commercial fisher, testified about a "film" which she saw on Brown's Creek near the St. Johns River. The substance was not identified. Nor was the source of the substance identified. Ms. James' belief that the film came from the North Landfill is not sufficient to support a finding of fact that the film whatever it was, came from the North Landfill. Mr. Mintz and Ms. James also testified about dead and diseased fish, and a dead dolphin and a dead manatee which they had seen in Clapboard Creek, Brown's Creek and other waters in the vicinity. No competent substantial evidence was presented to prove that the deaths or the disease was caused by waste disposed of at the North Landfill. No evidence concerning what killed the fish, dolphin or manatee, or what caused the diseased fish, was presented. Specific Condition 13 of the Permit requires the City to monitor water at three points along the stormwater disposal system of the North Landfill. One of the three monitoring points is approximately one-tenth of a mile east of the North Landfill in Brown's Creek. During approximately ten years of monitoring of water conditions only two parameters, iron and coliform, have been found in excess of state standards. The evidence did not prove what the cause of the excess iron and coliform was. It is possible that the excesses were caused by leachate from Phases I, II and 111a, which do not have lined leachate control systems like Phase IIIb, seeping into the stormwater disposal system. Leachate from Phase IIIb does not aggravate the problem because the leachate control system of Phase IIIb is lined. The City and the Department entered into a Consent Agreement on July 14, 1989 (hereinafter referred to as the Consent Order). Pursuant to the Consent Order the City is required to update its monitoring of stormwater. Quarterly monitoring of 37 parameters will be required. Specific Condition 19 A 2) of the Modified Permit also specifies that 37 parameters are to be analyzed quarterly. Specific Condition 13 A 2 of the Permit only required analyses of 14 parameters. The requested modification of the Permit should not contribute or extend any adverse affect of the North Landfill on water quality. The Consent Order and Specific Condition 20 C of the Modified Permit require that the City analyze 35 parameters quarterly at four wells located inside the North Landfill. The City has contracted for the preparation of a groundwater monitoring plan consistent with the Consent Order and with the requirements of Rule 17-701.050, Florida Administrative Code. Based upon a review of a well inventory conducted by the City and groundwater studies, wells in the vicinity of the North Landfill, including the well on Mr. & Mrs. Leigh's property and the M & M Dairy, are not at risk of contamination. The requested modification of the Permit should not increase the risk of contamination of wells in the vicinity of the North Landfill. Violation of Height Limits. In 1988 the City filled some portions of Phases I, II and IIIa above their 75 foot limit. The City did not, however, intentionally violate the Permit height limits. The City exceeded the height limit of the Permit only because it believed that solid waste placed on the landfill in excess of 75 feet would eventually settle to less than 75 feet and that this was consistent with the Permits limits. The Department disputed the City's actions in exceeding the 75 foot limit for Phases I, II and IIIa in an administrative action separate from this proceeding. On July 14, 1989, the City and Department settled their dispute and entered into the Consent Order. Pursuant to the Consent Order, the City paid a fine of $1,800.00. The City also built a laser tower for use in measuring the height of the North Landfill and agreed to use it to make more frequent surveys of the landfill. The City was not required to immediately remove the excess height. The City has been allowed to wait until closure. Prior to closure the City can request permission from the Department to leave the excess height. In the modification of the Permit at issue in this proceeding, Specific Condition 3 specifically provides for the manner in which waste may be disposed of in Phase IIIb in an effort to avoid the problems with excessive height experienced with Phases I, II and IIIa. B. Litter. Specific Condition 17 of the Permit provides that [l]itter control devices shall be installed as necessary to prevent litter from leaving the disposal area. Litter outside of the perimeter of the North Landfill along the roads leading to the landfill comes primarily from trucks bringing waste to the North Landfill. A small amount of the litter also comes from the site itself. Although the trucks are not City trucks, the City's litter collection efforts have been extended to cover the main portions of the roads leading to the North Landfill. Litter around and on the North Landfill has been a problem. The City has taken a number of steps to control the amount of litter in and around the landfill: Waste deposited at the North Landfill is covered with six inches of soil. Although the City is not required to do so, six months before the formal hearing of these cases the City began covering the area of the landfill where waste is being deposited (hereinafter referred to as the "working surface") with six inches of dirt. The working surface is also located away from wind. Fences have been installed around the perimeter of the North Landfill. Fences are also placed around the working surface on windy days. Prior to 1989 the City patrolled the immediate vicinity around the North Landfill to collect litter which had not been covered. Collection was performed on a variable time schedule. Only three part-time employees participated in the collection patrols. Beginning in early 1989, the City expanded its litter collection patrols. The roads surrounding the North Landfill (New Berlin Road, Faye Road, Alta Road and Island Drive), are now patrolled daily by five full- time employees. The extent of the patrols prior to 1989 and since early 1989 is depicted on City exhibit 8. The inside of the perimeter of the North Landfill is patrolled for litter collection five days a week and on the weekend, as needed. The stormwater ditches are inspected on a daily basis. At the time of the formal hearing of these cases the stormwater ditches and retention ponds were being excavated. This process had been going on for approximately four to six months. The Modified Permit contains Specific Condition 13, which is essentially the same as Specific Condition 17 of the Permit. Additionally, the Modified Permit contains Specific Condition 8, which provides: The Permittee shall maintain litter controls to prevent litter from entering the collection ditches and from leaving the landfill site. In addition to litter control fences, the Permittee shall provide daily manual collection of litter entering collection ditches and leaving the site. Litter can best be controlled by compacting the waste, picking up litter regularly and using fences. The City has employed these methods of litter control. The City's efforts have been reasonable. The proposed increase in height of Phase IIIb will not adversely affect the amount of litter associated with the North Landfill or the City's litter collection efforts. The City is not required to continue to patrol the roads leading to the North Landfill which it is currently patrolling to pick up litter that is attributable to trucks bringing waste to the North Landfill. Odor. There is no dispute that there is undesirable odor associated with the disposal of solid waste. This is true of the North Landfill. There is undesirable odor associated with the North Landfill most of the time. The nature of the odor associated with landfill's generally, and the North Landfill in particular, was described at the formal hearing as follows: Q The odor that you noticed, is it to some degree all the time? A Some days it won't, but that's very rare. Usually it may be more. Some days it may be in the afternoon, it may not smell in the morning, it may be in the afternoon. Some days it may be in the morning and may not be in the afternoon. Q Could you quantify what percentage of the time? A Probably about 75 percent of the time. Q And you indicate that at times it's much stronger than at other times? A Yes. Q You mentioned odor from the landfill. This was back in time now a good way. When did you start noticing an odor from that landfill? A When did I first start noticing it? Q Yes. A The very day they started dumping. Q And that odor has persisted since then? A Not every -- not every single day, but yes. Q Some days you will have it, some days you won't? A Yes. Q How many years are we talking about since they opened approximately? A Well, we have been out there 17 years. . Q So, over that 14 or 15 years, is it fair to say that basically you have an odor, and some days it will be worse than the average odor, and some days `it will be better than the average odor? A Yes. Transcript, page 511, lines 9-15, page 514, lines 9-13, page 516, line 25, and page 517, lines 1-21. Specific Condition 16 of the Permit provides that 1[o]bjectionable odors originating from the site shall be effectively controlled during all phases of operation. The most effective method of dealing with undesirable odor associated with landfills is to cover the waste daily and minimize the contact of waste with water. The City has been covering the waste disposed of at the North Landfill on a daily basis. The City's efforts have resulted in the North Landfill being as odor free as a "well run" landfill can be. A City ordinance provides for citizen participation in controlling odors in Jacksonville. This ordinance is enforced by the City's Bio- Environmental Services Division. As part of enforcing the odor ordinance the City provides a 24-hour telephone service which citizens can call and complain about odors. Since January, 1988, the City has received 5,500 complaints--an average of 280 complaints a month. Complaints received about odor are investigated by nine inspectors employed by the City. If five or more validated complaints are received about an odor producer during a 90-day period, the City issues a citation. Since January, 1988, the City has received only three complaints about the North Landfill from citizens. No citations have been issued against the North Landfill. Specific Condition 16 of the Permit is included in the Modified Permit as Specific Condition 15. The Modified Permit also includes Specific Condition 6, which provides: The Permittee shall apply no less than 6 inches of compacted initial cover to the top and sides of each cell by the end of each working day, except on the working face which may be left uncovered if additional solid waste will be placed on the working face within 18 hours. An intermediate cover of one (1) foot of compacted earth, in addition to the six (6) inch initial cover, shall be applied within seven (7) days of cell completion if final cover or an additional lift is not to be applied within 180 days of cell completion. The Permittee shall ensure that an adequate quantity of acceptable cover material is available for use during each day of operation of the landfill. The modification of the Permit will not increase the odor associated with the North Landfill. It will, however, extend the period of time that odors emanate from the North Landfill. Access to the North Landfill and Dust. Specific Condition 20 of the Permit provides that "[d]ust free, all- weather access roads to the site and active disposal area, or alternative wet weather disposal area shall be maintained." This condition has been complied with by the City. This condition is included as Specific Condition 12 in the Modified Permit. The roads used to access the North Landfill are paved, two-lane roads. The lanes are twelve feet wide. The speed limit on the access roads is 45 m.p.h. Appropriate turn lanes are available. During December, 1988, New Berlin Road and the North Landfill were able to effectively handle 600 trucks per day, an average of 80 to 90 trucks an hour during peak hours. Normally, the North Landfill effectively handles approximately 300 garbage trucks and 100 cover-dirt trucks a day with a peak of approximately 60 trucks per hour. The unpaved right-of-way on the side of the roads leading to the North Landfill is worn and the source of dust. Dust associated with the North Landfill comes from the roads leading to the landfill. The evidence failed to prove that dust comes from within the perimeter of the North Landfill. Tire Storage. Whole tires have been stored and processed at the North Landfill. At the time of the formal hearing there were more than 1,000 tires at the landfill. The evidence failed to prove how long any specific quantity of tires had been stored at the North Landfill. The City has not allowed the disposal of any whole tires at the North Landfill since July 1, 1989. The City has been shredding tires at the North Landfill. At the time of the formal hearing the City had contracted for the shredding of all the tires which had been located at the North Landfill at the time the contract was entered into in early July, 1989. The contract in existence at the time of the formal hearing was scheduled to expire in October, 1989. The City, however, expected to enter into a follow-up contract to continue shredding tires. In February or March, 1989, the previous tire- shredder contractor walked off the job. Mosquitoes at the North Landfill are managed by the City's Bio- Environmental Services Mosquito Control Division. Spraying is only done "as needed", however. F. Hazardous Waste, Oil Recycling and Infectious Waste. The City has not established an independent hazardous waste disposal program, a used oil recycling program or a infectious waste disposal program. The City attempts to prevent disposal of hazardous waste, used oil and infectious waste through educating the public with signs posted at the North Landfill entrance and periodic inspections of waste disposed of at the North Landfill. The evidence failed to prove that hazardous waste, used oil or infectious waste is being disposed of at the North Landfill. The evidence also failed to prove that approval of the Modified Permit will cause the disposal of hazardous waste, used oil or infectious waste on Phase IIIb of the North Landfill. Specific Condition 5 of the Modified Permit prohibits the disposal of hazardous waste and infectious waste at Phase IIIb of the North Landfill. This condition also requires that the City provide a minimum of one spotter for each working fact of Phase IIIb to watch for unauthorized waste.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a final order be issued by the Department approving issuance of the Modified Permit, modified by the inclusion of a Specific Condition requiring that the City continue its litter patrols as represented at the formal hearing.

The Issue The issue to be determined in this case is whether a supplemental site certification should be issued to Lee County for the construction and operation of Unit No. 3 at Lee County's Solid Waste Energy Recovery Facility (Facility), in accordance with the provisions of the Florida Electrical Power Plant Siting Act (PPSA), Sections 403.501 - .518, Florida Statutes. (All statutory references are to the 2002 codification of the Florida Statutes.)
Findings Of Fact The Applicant The Applicant, Lee County, is a political subdivision of the State of Florida. Lee County owns the existing Facility and will own Unit No. 3. The Facility was designed, built and is operated by a private company, Covanta Lee, Inc. (Covanta), pursuant to a long-term contract with Lee County. It is anticipated that Covanta or another private company will design, construct and operate Unit No. 3 for the County. History of the Project In 1985, the Florida Legislature enacted the Lee County Solid Waste Disposal and Resource Recovery Act (the Act), which authorized Lee County to construct, operate, and maintain a solid waste disposal and resource recovery system for the benefit of Lee County's residents. In 1989, pursuant to the Act, Lee County adopted an Integrated Solid Waste Management Master Plan (Plan), which established a comprehensive plan for the management, reuse, recycling and/or disposal of the solid waste generated in Lee County. Lee County's Plan was based on the development of: (a) an aggressive recycling program to reduce the quantity of materials requiring disposal; (b) a waste-to-energy facility for waste reduction and energy recovery from those materials that are not recycled; and (c) a landfill for the disposal of ash and by- pass waste (i.e., materials that are not recycled or processed in the waste-to-energy facility). Lee County has implemented its Integrated Solid Waste Management Plan with innovative approaches and state of the art technology. Lee County has a comprehensive recycling program that handles a wide array of materials, including: (a) waste from residential, commercial, governmental, and institutional facilities; (b) household hazardous waste; (c) yard waste; (d) recovered materials; (e) construction and demolition debris; and (f) electronic waste. Lee County established a recycling and materials separation goal of 40 percent for its residents, even though the State of Florida's goal is 30 percent. From 1993 through 2000, Lee County exceeded the State's 30 percent goal. In 1998, Lee County's recycling rate was approximately 38 percent, which was higher than that of any other county in Florida. Consistent with its Plan, Lee County built a modern landfill, which is equipped with two synthetic liners, two leachate collection systems, and a network of groundwater monitoring wells to ensure the protection of the environment. Lee County's landfill is located in Hendry County, pursuant to an interlocal agreement between Lee County and Hendry County. Under this agreement, the solid waste from both counties is taken to Lee County's Facility for processing and then the ash and by-pass waste are taken to the landfill for disposal. This cooperative, regional approach to solid waste management issues has enabled Lee County and Hendry County to provide environmentally sound, cost-effective programs for the residents of both counties. In 1992, the Governor and Cabinet, sitting as the Siting Board, approved the construction and operation of Units No. 1 and No. 2 at the Facility, and certified an ultimate site capacity of 60 megawatts (MW), based on the operation of three municipal waste combustor (MWC) units. Units No. 1 and No. 2 have been in commercial operation since 1994. Despite Lee County's comprehensive recycling program, the amount of solid waste delivered to the Facility has increased each year since the Facility began operation, primarily due to population growth. In 1999, Lee County's solid waste deliveries were equal to the Facility's guaranteed processing capacity (372,300 tons). In 2000, the Facility processed more than 392,000 tons of solid waste, but the County still had to dispose of nearly 44,000 tons of processible waste in its landfill. Current population projections for Lee and Hendry Counties suggest that the amount of processible solid waste will continue to increase, reaching almost 550,000 tons by 2010. Lee County has decided that it should expand the Facility, consistent with Lee County's long-standing Plan, rather than discard processible waste in a landfill. The Facility was designed to readily accommodate the construction of a third MWC unit. If approved and built, the third unit (Unit No. 3) will be operating at or near its design capacity by 2010 (i.e., within five years after it commences commercial operations). For these reasons, on November 18, 2002, Lee County filed its Supplemental Application with DEP for the construction and operation of Unit No. 3. The Site The Facility is located east of the City of Fort Myers, in unincorporated Lee County. The Facility is approximately 2.5 miles east of the intersection of Interstate-75 and State Road 82, on the north side of Buckingham Road. The County owns approximately 300 acres of land at this location, but only 155 acres (which constitutes the Site) was certified under the PPSA for the Facility. The Site currently includes the Facility, a household hazardous waste drop-off area, a waste tire storage facility, a horticultural waste processing area, and a recovered materials processing facility. A solid waste transfer station is under construction at the Site. Even after the Facility is expanded to accommodate Unit No. 3, approximately 63 percent of the Site will be used solely as buffer and conservation areas. The Surrounding Area There are large buffer areas around the Site. A Florida Power & Light Company (FPL) transmission corridor, containing electric transmission lines, is located along the western boundary of the Site. Approximately three-quarters of a mile to the west of the Site is a limerock, fill, and topsoil mining operation. Immediately north of the Site is approximately 145 acres of undeveloped land owned by the County. A 135-acre County-owned park is adjacent to the Site's eastern property line. Scattered single-family homes are located northeast and farther east of the Site. An adjacent parcel southeast of the Site was previously used as a sanitary landfill (which has been closed and covered), and is now owned by the City of Fort Myers and private individuals who use it for livestock grazing. The land immediately south of the Site is undeveloped. The Gulf Coast Sanitary Landfill is located three miles directly south of the Site. Site Suitability The Site is well-suited for the addition of Unit No. 3. The Site has sizable buffer areas on all sides. Potable water, reclaimed water, and wastewater services are already provided to the Site through existing pipelines. The Facility is near an existing electrical substation (Florida Power & Light Company's Buckingham Substation). An existing electrical transmission line connects the Facility to the substation. Zoning and Land Use In 1991, the Siting Board determined that the Site and Facility are consistent and in compliance with the applicable land use plans and zoning ordinances, based on the construction and operation of three MWC units at the Facility. The Site was zoned for an Industrial Planned Development, and was designated as Public Facilities in the future land use map of Lee County's comprehensive land use plan, specifically to allow the Facility to be built and operated on the Site. The Existing Facility The Facility currently consists of Units No. 1 and No. 2, which have been in commercial operation since 1994. Each MWC unit has a nominal capacity of 600 tons per day (tpd) of solid waste (660 tpd using a reference fuel with a higher heating value of 5000 British thermal units per pound (Btu/lb)). The two MWC units generate steam that is used to drive an electric turbine generator, which generates approximately 39 MW of electricity. The Facility also includes an ash management building, cooling tower, stack, stormwater management ponds, water treatment system, electrical switchyard, electrical transmission lines, and related facilities. Solid waste collection trucks enter the Site from Buckingham Road. They follow an access road to the County's scale house, where the trucks are weighed, and then the trucks are directed to the Facility. The trucks drive inside the Facility and dump the garbage into a refuse pit. A crane mixes the garbage in the pit. The crane then places the garbage in a hopper, which feeds into the combustion chamber where the garbage is burned. The air in the combustion chamber passes through the Facility's air pollution control equipment, and then out the stack. Ash from the combustion process is quenched and then is deposited onto an enclosed conveyor, which takes the ash to an ash management building. The ash then is loaded into trucks and taken to the County's existing landfill in Hendry County. As a result of this process, the amount of fill being taken to the existing landfill is reduced by approximately 90 percent. The New Project-MWC Unit No. 3 The Project involves the construction and operation of a new MWC unit (Unit No. 3) at the Facility. The new unit will be substantially the same as the two existing MWC units. The new unit will have the capacity to process 600 tpd (nominal) of solid waste (660 tpd at 5000 Btu/lb). A new electric turbine generator will be installed and it will generate approximately 20 MW of additional electricity. In addition, the cooling tower will be expanded, the ash management building will be expanded, a lime and carbon silo will be installed, and the new unit may be connected with the two existing units. Construction of Unit No. 3 The Facility was originally designed and built to accommodate the addition of a third MWC unit, thus making the construction of Unit No. 3 relatively simple, without disrupting large areas of the Site. Unit No. 3 will be located adjacent to the two existing MWC units. The expansion of the cooling tower will be adjacent to the existing cooling tower. Construction of Unit No. 3 will occur in previously disturbed upland areas on the Site. Construction of Unit No. 3 will not impact any wetlands or environmentally sensitive areas on the Site. No new electrical transmission lines or improvements will need to be built to accommodate the additional electrical power generated by Unit No. 3. No new pipelines or other linear facilities will need to be built for the Project. Operation of Unit No. 3 The basic operation of the Facility will not change when Unit No. 3 becomes operational. Solid waste will be processed at the Facility in the same way it is currently processed. The Facility has been in continuous operation since 1994, and has an excellent record for compliance with all applicable regulations, including regulations concerning noise, dust, and odors. All of the activities involving solid waste or ash occur inside enclosed buildings. The refuse pit is maintained under negative air pressure, thus ensuring that dust and odors are controlled within the building. Because the operations at the Facility will remain the same after Unit No. 3 becomes operational, no problems are anticipated due to noise, dust or odors. The Facility's basic water supply and management system will remain the same after Unit No. 3 becomes operational. Treated wastewater from the City of Ft. Myers' wastewater treatment plan (WWTP) will be used to satisfy the Facility's need for cooling water. Potable water will be provided to the Facility from the City's water supply plant. On-site wells will be available for emergency water supply purposes; however, the wells have not been regularly used as a source of back-up cooling water since the Facility became operational. The County's water supply plan maximizes the use of reclaimed water and minimizes the use of groundwater. To the extent feasible, the Project uses all of the reclaimed water that is available before it relies on groundwater. The Facility also recycles and reuses water to the greatest extent practicable. Unit No. 3 will not discharge any industrial or domestic wastewater to any surface water or groundwater. Most of the wastewater from the cooling tower will be recycled and reused in the Facility. Any excess wastewater will be discharged to the City of Fort Myers' WWTP. Stormwater runoff from the Project will be collected and treated in the existing system of swales and detention/ retention ponds on the Site. Ultimate Site Capacity The construction of Unit No. 3 will not expand the Facility beyond the boundaries of the Site certified by the Siting Board in 1992. The operation of Unit No. 3, together with the operation of Units No. 1 and No. 2, will not increase the electrical generating capacity of the Site beyond the 60 MW certified by the Siting Board in 1992. Air Quality Regulations The County must comply with federal and state New Source Performance Standards (NSPS) and Best Available Control Technology (BACT) requirements, both of which impose strict limits on the Facility's airborne emissions. The County also must comply with Ambient Air Quality Standards (AAQS) and Prevention of Significant Deterioration (PSD) standards, which establish criteria for the protection of ambient air quality. The addition of Unit No. 3 must undergo PSD review because the Project is a new source of air pollution that will emit some air pollutants at rates exceeding the threshold levels established under the PSD program. PSD review for the Project is required for airborne emissions of particulate matter less than 10 microns in diameter (PM10), MWC metals, MWC organic compounds, MWC acid gasses, sulfur dioxide (SO2), nitrogen oxides (Nox), carbon monoxide, mercury, fluorides, and sulfuric acid mist (SAM). Best Available Control Technology A BACT determination is required for each pollutant for which PSD review is required. BACT is a pollutant-specific emission limit that provides the maximum degree of emission reduction, after taking into account the energy, environmental, and economic impacts and other costs. As part of the BACT determination, all available and feasible pollution control technologies being used worldwide are evaluated. As part of its BACT analyses, DEP determined that a fabric filter baghouse will control the Facility's emissions of particulate matter, a scrubber will control acid gases, a selective non-catalytic reduction system (SNCR) will control NOx, an activated carbon injection system (ACI) will control mercury emissions, and proper facility design and operating methods will control other pollutants. These air pollution control technologies are currently used in Units No. 1 and No. 2, and they have performed extremely well. Units No. 1 and No. 2 are among the best operated and controlled MWC units currently operating in the United States. Unit No. 3 will have better, more modern, and more sophisticated air pollution control systems than Units No. 1 and No. 2. In its PSD analysis for the Project, DEP determined the emission limits for the Project that represent BACT. All of the BACT emission limits determined by DEP for Unit No. 3 are as low as the limits established by the United States Environmental Protection Agency (EPA) in the NSPS (40 CFR 60, Subpart Eb) for new MWC units, based on the use of Maximum Achievable Control Technology (MACT). Indeed, DEP's BACT emission limits for Unit No. 3 are lower than EPA's MACT emissions limits for: (a) particulate matter; (b) sulfur dioxide; (c) carbon monoxide; (d) nitrogen oxides; and (e) mercury. The BACT emission limits, as determined by DEP, are included in the proposed Conditions of Certification for Unit No. 3. The Facility's proposed air pollution control systems are proven technologies that can achieve the proposed BACT emission limits. The Facility will use an array of continuous emissions monitors to help ensure that the Facility is continuously in compliance with the BACT emission limits. Protection of Ambient Air Quality The EPA has adopted "primary" and "secondary" National Ambient Air Quality Standards (NAAQS). The primary NAAQS were promulgated to protect the health of the general public, including the most susceptible groups (e.g., children, the elderly, and those with respiratory ailments), with an adequate margin of safety. The secondary NAAQS were promulgated to protect the public welfare, including vegetation, soils, visibility, and other factors, from any known or anticipated adverse effects associated with the presence of pollutants in the ambient air. Florida has adopted EPA's primary and secondary NAAQS, and has adopted some Florida AAQS (FAAQS) that are more stringent than EPA's NAAQS. Lee County and DEP analyzed the Project's potential impacts on ambient air quality, using conservative assumptions that were intended to over-estimate the Project's impacts by a wide margin. These analyses demonstrate that the maximum impacts from Unit No. 3 will be less than one percent of the amount allowed by the ambient air quality standards. The maximum impact from the Facility (i.e., all three units) will be less than or equal to 1.2 percent of the amount allowed by the FAAQS and NAAQS. Unit No. 3 and the Facility will not cause or contribute to any violations of the FAAQS or NAAQS. The maximum impacts of Unit No. 3 and the Facility, when operating under worst case conditions, will be less than the regulatory levels that are deemed "significant" (i.e., less than the numerical thresholds set by EPA as "significant impact levels"). The Facility's impacts on ambient air quality will be immeasurably small and will be indistinguishable from ambient background conditions. Non-criteria pollutants are substances for which there are no AAQS. The Department's Air Toxics Group has established non-enforceable guidelines known as ambient reference concentrations (ARCs) (also known as "No Threat Levels") for the non-criteria pollutants. DEP believes there is no health or environmental threat associated with ambient air impacts less than the ARCs. In this case, the maximum impacts of the Facility (3 MWC units) will be less than 50 percent of any of DEP's ARCs. For most parameters, the Facility's maximum impacts are less than 10 percent of the applicable ARCs. Other PSD Analyses The PSD program provides protection for those areas that have good air quality. Different areas of Florida have been designated as PSD "Class I" or "Class II" areas, depending upon the level of protection that is to be provided under the PSD program. In this case, the Project is located in a PSD Class II area. The nearest PSD Class I area is the Everglades National Park (Everglades), which is approximately 90 kilometers (km) south-southeast of the Site. The analyses performed by Lee County and DEP demonstrate that the Project's impacts on the ambient air quality in the vicinity of the Site will be insignificant. The analyses performed by Lee County and DEP also demonstrate that the Project's impacts on the ambient air quality in the PSD Class I area at the Everglades will be insignificant. The Project will not significantly affect visibility in the Class I area, regional haze, or other air quality-related values. Compliance With Air Standards Lee County has provided reasonable assurance that the Project will comply with all of the applicable state and federal air quality standards and requirements. Among other things, Lee County has provided reasonable assurance that the airborne emissions from the Project, alone and when operating with the two existing MWC units at the Facility, will not: (a) cause or contribute to the violation of any state or federal ambient air quality standard; (b) cause or contribute to a violation of any PSD increment for any PSD Class I or Class II area; (c) cause any adverse impacts on human health or the environment; (d) exceed any ARC guideline established by DEP for non-criteria pollutants; or (e) cause any adverse impacts to soils, vegetation or wildlife. Lee County also has provided reasonable assurance that Unit No. 3 and the Facility will be able to comply with the Conditions of Certification involving air issues. Human Health and Ecological Risk Assessments As indicated above, the County has performed extensive analyses of the Facility's emissions and impacts to demonstrate compliance with the requirements of state and federal air quality regulations. In addition, the County has taken other measures to address public concerns about the potential impacts associated with the Facility's airborne emissions. In 1992, the County's expert consultants conducted a human health and ecological risk assessment, which evaluated the potential impacts associated with the airborne emissions of mercury and dioxin from the County's Facility. The assessment demonstrated that the operation of the Facility would not adversely affect humans or threatened or endangered species. At the request of the United States Fish and Wildlife Service, the County conducted a supplementary risk assessment in 1992, to more thoroughly evaluate the potential impact of the Facility's mercury emissions on the Florida panther. Among other things, the supplementary assessment evaluated the panther's exposure to mercury through a complex food chain. The County's supplementary assessment confirmed that the Facility would not cause adverse impacts to the panther. The County also initiated a biomonitoring program, which was designed in conjunction with the U.S. Fish and Wildlife Service to identify background concentrations and trends for mercury in key indicator species within the local aquatic environment (i.e., largemouth bass, oysters, and mosquitofish). The County's biomonitoring program was started in 1993, and continued after the County's Facility commenced operations in 1994. The data collected in the biomonitoring program indicate that the mercury concentrations in these key species have not increased as a result of the operation of the Facility. In 2002, the County's consultants completed a new, large-scale, evaluation of the human health and ecological risks associated with the Facility's airborne emissions. The County's 2002 risk assessment evaluated the cumulative impacts of the entire Facility, with all three MWC units in operation. The County's 2002 risk assessment was conducted in compliance with current EPA guidance. The risk assessment considered hypothetical human receptors (e.g., infants, children, and adults) that were engaged in different types of behavior (e.g., a typical resident; a beef farmer; a subsistence fisherman) and were exposed through multiple pathways (e.g., inhalation; ingestion of soil; ingestion of local produce, beef and/or fish) to both acute short-term and chronic long-term impacts from the Facility. The risk assessment was designed to overestimate the potential impacts of the Project, and thus be protective of human health and the environment. The risk assessment relied upon the latest EPA data for mercury, dioxin, and the other chemicals of concern, as set forth in EPA's 1997 Mercury Report to Congress, EPA's 2000 Dioxin Reassessment, and other relevant documents. The County's 2002 risk assessment demonstrates that the Facility's airborne emissions will not measurably increase the typical concentrations of chemicals in the environment. For example, even at the point of maximum impact, the maximum environmental mercury and dioxin concentrations associated with the operation of the Facility will be far below the levels that are typically found in the environment and they will be immeasurably small. The County's 2002 risk assessment also demonstrates that the potential risks associated with the Facility's emissions will not exceed, and in most cases will be much less than, the risks that are deemed acceptable by the EPA and DEP for the protection of human health and the environment. The County's findings are consistent with the findings in environmental monitoring studies and risk assessments that have been performed for other modern waste-to-energy (WTE) facilities in the United States. Indeed, the environmental monitoring studies conducted at similar WTE facilities have shown that risk assessments, like the ones performed for Lee County, overestimate the actual impacts. In light of the evidence presented by the County in this case, the Facility should not have any measurable effect on human health or the environment, even when all three MWC units are operational. Other Potential Environmental Impacts The County's 2002 risk assessment primarily focused on the Facility's maximum impacts under worst case operating conditions. The maximum concentrations in the ambient air and the maximum deposition rates resulting from the Facility's mercury emissions will occur within 2.5 km (approximately 1.5 miles) of the Site. The ambient air concentrations and deposition rates at all other locations beyond the Site will be even lower. EPA studies of similar facilities have shown that mercury deposition rates decrease at least 100 times (i.e., by a factor of 100) within the first 10 km. In this case, the nearest portions of the Everglades are approximately 90 km from the Site. Moreover, the generally prevailing winds at the Site blow toward the Gulf of Mexico, not toward the Everglades. Approximately 90 percent of the time, the wind does not blow from the Site toward the Everglades. For these and other reasons, the Facility's mercury emissions will have an insignificant impact on the Everglades. The Facility's emissions of nitrogen oxides (i.e., NOx) will not cause or contribute to violations of any water quality standards in any surface waterbody. Environmental Benefits of the Project The addition of Unit No. 3 will provide significant environmental benefits to Lee County and Hendry County. The solid waste processed by Unit No. 3 will reduce the volume of processible solid waste by approximately 90 percent. By reducing the volume of processible waste, the Facility will significantly extend the useful life of the Lee County/Hendry County regional landfill, effectively postponing the need to build a new landfill in Lee County or Hendry County. The Project will also provide environmental benefits to the State of Florida. For example, the Facility will produce approximately 1.88 billion kilowatt-hours of electricity from discarded materials during the next 20 years. In this manner, Unit No. 3 will reduce the need to use fossil fuels to generate electricity at traditional power plants. Unit No. 3 will eliminate the need to use approximately 5.54 million barrels of oil, and thus will save approximately $150 million in oil purchases over the next 20 years. In addition, the County will recover ferrous and non-ferrous metals from the Facility's ash, thus recycling resources that otherwise would be buried with the County's solid waste in a landfill. Socioeconomic Benefits of the Project The local economy and labor market will benefit from approximately $70 million that Lee County will spend to construct the Project. A significant amount of construction supplies, such as concrete, structural steel, glass, piping, fittings, and landscape materials, are anticipated to be purchased from local businesses. The Project will provide jobs for over 125 construction workers during the peak of construction activities. The addition of Unit No. 3 will also provide approximately nine new permanent jobs at the Facility, with an increase in the Facility's annual payroll of approximately $400,000. WTE Criteria in Section 403.7061 Section 403.7061, Florida Statutes, establishes several criteria that must be satisfied before an existing waste-to- energy facility may be expanded. Lee County has provided reasonable assurance that the Project will satisfy all of the standards and criteria in Section 403.7061, Florida Statutes. Among other things, the County has demonstrated that Lee County's waste reduction rate will exceed 30 percent when Unit No. 3 begins operation. Compliance with Environmental Standards Lee County has provided reasonable assurance that the Project will comply with all of the nonprocedural land use and environmental statutes, rules, policies, and requirements that apply to the Project, including but not limited to those requirements governing the Project's impacts on air quality, water consumption, stormwater, and wetlands. The location, construction, and operation of the Project will have minimal adverse effects on human health, the environment, the ecology of the State's lands and wildlife, and the ecology of the State's waters and aquatic life. The Project will not unduly conflict with any of the goals or other provisions of any applicable local, regional or state comprehensive plan. The Conditions of Certification establish operational safeguards for the Project that are technically sufficient for the protection of the public health and welfare, with a wide margin of safety. Agency Positions and Conditions of Certification On December 11, 2001, the PSC issued an order concluding that the Project was exempt from the PSC's "determination of need" process, pursuant to Section 377.709(6), Florida Statutes. DEP, DOT, DCA, and SFWMD all recommend certification of the Project, subject to the Conditions of Certification. The SWFRPC determined that the Project is "Regionally Significant and Consistent with the Regional Strategy Plan," but did not recommend any conditions of certification for the Project. Lee County has accepted, and has provided reasonable assurance that it will comply with, the Conditions of Certification.
Recommendation Based on the foregoing Findings of Facts and Conclusions of Law, it is RECOMMENDED that the Governor and Cabinet, sitting as the Siting Board, enter a Final Order granting a supplemental site certification for the construction and operation of Unit No. 3 at the Lee County Solid Waste Energy Recovery Facility, in accordance with the Conditions of Certification contained in Appendix 1 to DEP Exhibit 2. DONE AND ENTERED this 19th day of August, 2003, in Tallahassee, Leon County, Florida. S _________________________________ RICHARD A.

Findings Of Fact On April 29, 1983, the Respondent Waste Aides Systems, Inc. (hereafter referred to as Waste Aides), filed with the Department of Environmental Regulation (Hereafter referred to as DER) an application to construct and operate a solid waste transfer station. The proposed transfer station would be located at the site of an existing solid waste landfill at Ridge Road and Landfill Road, New Port Richey, Florida. On May 24, 1983, DER, by letter to Waste Aides, requested additional information concerning the permit application and seeking further assurances with regard to control of wash down water and storm water runoff. On June 7, 1993, Waste Aides, by letter provided the additional information, and on June 14, 1983, DEP issued a letter of intent to issue the permit to Waste Aides. The proposed facility is to be located on a parcel of land previously used as a solid waste landfill, but the area where the facility is to be built is not a previously filled solid waste area. The proposed facility will utilize a building which is enclosed on the south, east, and west, and open to the north. The building will be approximately 120 feet wide, 48 feet deep, and 31 to 34 feet high. The general operation of the facility will be to transfer residential and commercial solid waste from garbage trucks to large tractor-trailer trucks for transport to a more isolated solid waste landfill. The facility will not accept hazardous waste or heavy industrial waste. The solid waste will be transported to the facility in garbage trucks. The solid waste will be dumped on a concrete floor inside the building and will then be pushed into a loading chute which sits directly above a waiting trailer. Once the trailer is filled, the solid waste is then transported to an offsite landfill where it is ultimately disposed of. Security at the facility will be accomplished through fencing and gates. The entire property is surrounded by a fence. A gate will be placed at Ridge Road, and a second gate will be installed at the entrance to the property itself. No unauthorized vehicles will be permitted to enter the property or unload solid waste at the facility. The facility will be equipped with two fire control hoses located on the east and west walls of the building. Potable water will be provided to the facility through a hookup to a 16-inch water main at Ridge Road. The facility will have impact sprinklers and spray bars inside the loading chute. Each vehicle on site will be equipped with a fire extinguisher, and two portable fir extinguishers will be located inside the building at appropriate locations. The impact sprinklers will also be utilized for dust control. Each vehicle on site will be equipped with a two-way radio which provides contact with the administrative office and maintenance area of the applicant. The phone in the cardboard recycling facility located on the same property of the proposed facility will be available for use by the operator of other employees of the transfer facility. The recycling facility is owned and operated by the applicant and is directly adjacent to the proposed transfer facility. The operator will be responsible for keeping records of materials handled by the facility. A recordation of volume will be measured and entered as collection trucks discharge their contents at the facility. A scale will be built into the loading area of the transfer trailers, and the weight of all refuse transferred will be recorded by load on a daily basis. These records will be open during normal business hours for inspection by DER representatives, health inspectors, and other authorized regulatory and enforcement agencies. The transfer station operator will be the foreman of the facility and will be present during all hours of operation. The tractor-trailer operator and the operators of the garbage trucks will be present at the facility during unloading and loading. Two or three other employees will also be present on the grounds at varying times for cleanup, grounds work, and other duties at the facility. The facility will be visited and checked approximately twice daily by William R. Peterson and his brother, the owners and operators of the proposed facility. The applicant has available personnel presently in the employment of the applicant, who is a certified driving instructor and who is skilled in the instruction of safe and efficient operating procedures. Additionally, Waste Aides will provide instructions in first-Aides procedures by a person presently employed who is a trained emergency medical technician. Debris will be controlled by certain mechanisms built into the design of the building and by certain operational procedures that will be observed by the transfer station operator. The tipping floor where solid waste is discharged will be enclosed on three sides. When the solid waste is discharged onto the tipping floor, it is immediately pushed into a chute which allows it to fall into the waiting transfer trailer. There is approximately an 8-inch tolerance between the chute and the top of the trailer, and the chute has been designed to angle in toward the trailer so that solid waste will be directed into the trailer to avoid spillage. Additionally, a rubber or fabric membrane will encircle the chute so that when the transfer trailer drives beneath it, the membrane will be inside the transfer trailer, thus directing all solid waste into the trailer itself. An additional benefit of this design is that it will avoid the possibility of drafts of air blowing refuse in the trailer over its sides. The trailer area itself is depressed and thus out of the direct wind stream. Drafts are further buffered by vegetation windbreaks consisting of trees and shrubs located on the west and south sides of the building and by the topographical nature of the surrounding lands on the other two sides. The entire area of the transfer station is fenced as a final barrier to debris escaping the transfer station site. The refuse will normally be on the tipping floor a very short period of time because of the fact that it will be pushed into the transfer trailer immediately upon discharged from the collection vehicle. The refuse, as it is discharged from the collection vehicle, does not lend itself to a debris problem in that it is in a compressed state and tends to remain in a semifragmented mass until it is moved into the trailer. The entire transfer station and surrounding grounds will be cleaned at the end of each day by the station operator. The station will be operated at all times to be in compliance with the applicable noise regulation and ordinances of Pasco County. For noise abatement, Waste Aides has designed the building with noise control in mind. The tipping floor will be constructed with steel rails imbedded in the concrete to eliminate the noise of the front-loading metal bucket scraping on the concrete surface. Six-foot walls buffet all sides of the tipping floor except the north side. The north side is open to an approximate 10-acre tract which was the previous landfill site and will be unoccupied. The tipping floor is enclosed by a building which will provide a significant amount of noise control in a and of itself. There are vegetation screening barriers and earthen berms on the north, west, and south boundaries of the site. The berms will be covered with mature vegetation and will act a both a noise and visual barrier for the site. All equipment used in the operation will meet all county, state, and federal operational decible standards. Odor control will be provided primarily by operational standards which will emphasize the rapid removal of refuse from the site. All refuse will be removed daily except for the possibility of partially filled trailers remaining overnight on site. Should a transfer trailer be required to remain on the site overnight, it will be driven inside the building not less than every 48 hours or in accordance with an approved DER schedule. The tipping floor will be completely cleaned at the end of each workday by being swept broom-clean and then washed down with hoses. When the floor is washed down, the water and debris will flow along the sloped floor to a grid system which will direct the flow into a sand trap and a grease trap and then into a septic tank. The traps will be checked each day after wash down and will be cleaned periodically. The building has been designed in such a manner that no square corner will exist for the possible buildup of refuse. These same operational procedures and design features will discourage any attraction to vermin or birds. Similar transfer station operations in Florida have not experienced the vermin and odor problems typically associated with landfill site operations. The prosed facility will have electric service available. Shelter as well as hand-washing and toilet facilities are available for employees for the facility at the adjacent recycling building. Maintenance on trucks and other equipment will be performed at the applicant's maintenance area located on Osteen Road, approximately 1 to 1 1/2 miles from the proposed facility. Although the proposed facility is surrounded by developed residential areas, the property which is directly contiguous to the property where the proposed facility will be located remains undeveloped. The objectors' travel- trailer park is the closest developed area, and the distance from the nearest trailer to the proposed facility is approximately 950 feet. The design and proposed operation of the transfer station meets or exceeds the criteria contained in Rule 17-7.09, Florida Adminstative Code. Numerous residents in the area object to the location of a garbage transfer station. Their objections are based upon their experience with odor, vermin, birds, and litter experienced in connection with the landfill operation. However, the uncontradicted evidence established that those problems will not exist to any substantial degree in connection with the operation of the proposed garbage transfer station.
Recommendation Based upon the foregoing findings of fact and conclusions of law, it is RECOMMENDED That the Department of Environmental Regulation issue a permit to Waste Aides Systems, Inc., for the construction and operation of the proposed transfer station, subject to the specific conditions contained in DER's Notice of Intent. RECOMMENDED this 4th day of January, 1984, in Tallahassee, Florida. MARVIN E.

Findings Of Fact On November 1, 1985, Broward County filed an application with the Department of Environmental Regulation (Department) for a solid waste construction permit, and on August 23, 1985, an application for a dredge and fill permit. The permits would have allowed Broward County to construct a Class I landfill in southwestern Broward County, Florida. On April 19, 1986, the Department gave notice of its intent to issue the requested solid waste permit, and on November 13, 1986, gave notice of its intent to issue the dredge and fill permit. Petitioners filed a timely request for formal hearing on each permit, and their petitions were consolidated for hearing.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED: That the solid waste permit and the dredge and fill permit sought by Broward County be ISSUED. DONE AND ORDERED this 18th day of May, 1987, in Tallahassee, Florida. WILLIAM J. KENDRICK Hearing Officer Division of Administrative Hearings The Oakland Building 2009 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 18th day of May, 1987.
Findings Of Fact On November 16, 1983, Lamar Advertising Company submitted it's applications for permits for outdoor advertising signs to be located on the north side of Interstate Highway 10 in Escambia County Florida, 4.8 miles west of the intersection of I-10 and U.S. Highway 90A facing east, and the other to be located on the west side of I-10, 5.08 miles west of its intersection and U. S. 90A facing east. By letter dated November 28, 1983, the Department rejected these applications, stating: In unpermitable zoning. No commercial business visible. Escambia County, Florida, owns the land where the proposed signs would be located. This parcel contains approximately from the Perdido River, the state bounds almost to County Road 99 on the east, with frontage of I-10 for a distance of approximately one mile * Station is located on the south side of I-10 opposite center of this parcel. In January of 1981, the construction of a sanitary landfill this property, known as the Perdido Landfill. permanent buildings located there, one of which house which includes computer equipment and two commercial scales. Another houses p* equipment. Another is used for employee loc* of supplies. Another is the main office. all office facilities and a major garage automotive and heavy equipment. sanitary landfill is used for disposal of solid waste through escavation and burial. Excavation removes soil which is later used to cover waste placed into the hole created by the NOTE: Page 2 of the Recommended Order on file with DOAH has missing or unreadable text and is therefore not available in this ACCESS document. excavation. When a filling operation has been completed in a particular area, there will be built up heights exceeding the existing grade by as much as 50 feet. Before the landfill activity began, the parcel in question was rolling landscape, mostly in pasture land with some timber. It sloped to the west to the Perdido River. It also sloped from north to south towards the north edge of Interstate 10. Escambia County has approximately thirty pieces of equipment on the Perdido Landfill. This equipment consists of two landfill compactors, two bulldozers, three self-elevating scrapers, a frontend loader, a number of dump trucks, a road grader, a hydraulic backhoe, three tractor trailer rigs, a rented dragline, and numerous cars and pickup trucks. Normally there are five pieces of this equipment in operation on any given day. In addition to the equipment operated by Escambia County, approximately 500 vehicles per day visit the landfill to dump solid waste Monday through Friday, of which about 300 are commercial and 200 are private vehicles. On Saturday approximately 800 to 1,000 vehicles visit the landfill to dump waste. These dumping operations on the Perdido Landfill are taking place about 800 to 1,000 feet from the north right-of-way of I-10. In addition, the County has leased 10 acres on the north boundary of this property to a private company which operates a treatment facility for the processing of septic waste material to produce fertilizer. This facility is located between 2,000 and 3,000 feet from the south boundary of the County property. The County has constructed and maintains an earth barrier approximately 100 feet wide along the south boundary of this property on I-10 to hide the landfill operation from traffic on the interstate. This earth barrier also places the private septic waste facility beyond the line of sight from the interstate. In addition, there are trees and other natural growth along the south boundary of the County property which obscures the site from view. Photographs admitted into evidence show that the activities taking place on the landfill are not clearly visible to traffic moving on I-10. None of the vehicles can be seen except the top portion or boom of a crane. The area is hidden by trees and by the earth barrier except for one or two small openings which reveal the crane's boom. A motorist traveling east on I-10 can see through these openings for approximately one second, and traveling west for only a couple of seconds. Nevertheless, some portion of the equipment being used on the landfill property is visible from the interstate. Most of the area of Escambia County outside of the City of Pensacola is not zoned. There are some areas in the vicinity of the University of West Florida in the northwestern part of the county and on Perdido Key in the southwestern part of the county that are zoned. The area in which the Perdido Landfill is located is not zoned. The Petitioner presented the former County Attorney for Escambia County who testified that the activities conducted at the landfill are compatible with an industrial zoning classification. No further evidence on this point was presented by the Petitioner. The Department presented the Administrator Director for zoning and inspection in Okaloosa County, Florida, who testified that there are four sanitary landfills in Okaloosa County, two located on federal land and two located on county property. Okaloosa County is located about 39 miles east of Escambia County, and the four landfills there are operated and maintained by the County. Okaloosa County has county-wide zoning, and sanitary landfills are classified as public service facilities in agricultural areas predominantly. Under the existing Okaloosa County ordinance,, a landfill would be classified as Agricultural or Agricultural Restricted, regardless of the type of landfill it is. The Department also presented a letter from the Land Use Administrator of the Tallahassee-Leon County Planning Department which indicates that Leon County considers sanitary landfills as "resource development activities" which are permitted as a restricted use only in agricultural zoned areas. This hearsay evidence is not of sufficient quality to support a finding of fact, but it corroborates the evidence presented by the Okaloosa County zoning director, and was admitted for this purpose.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Transportation enter a Final Order denying the application of Lamar Advertising Company for permits to erect two signs on the north side of I-10 in Escambia County, at points 4.80 miles and 5.08 miles west of U.S. 90A, facing east. THIS Recommended Order entered this 8th day of June, 1984, in Tallahassee, Florida. WILLIAM B.
