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 is whether Respondents should have an administrative penalty imposed, take corrective action, and pay investigative costs for allegedly maintaining a solid waste management facility without a permit and disposing of solid waste in an area subject to periodic or frequent flooding.
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: Background DDD is a corporation registered to do business in the State of Florida. Its president and sole director is William H. Stanton, Jr. The corporation is engaged in the business of "mobil recycling activities" (reduction recycling services for customers). Mr. Stanton owns a two-acre tract of property located in Section 26, Township 28S, Range 24B, on the northwest corner of Mustang Road and Longhorn Drive, Lakeland, Florida. The property is zoned for heavy industrial uses and was formerly used in some form of phosphate mining operations. The Department is the agency charged with the duty of administering and enforcing the provisions of Chapter 403, Florida Statutes, and rules promulgated thereunder. Based upon a complaint made by a Polk County Health Department employee, on October 8, 2001, a Department enforcement coordinator, Steven G. Morgan, inspected Mr. Stanton's property and observed that Respondents had filled and compacted an approximate 150 foot by 300 foot area of the site with 3 to 5 feet of "wallboard type material," which consisted of "both ground up and large pieces of wallboard." In the middle of the filled area was an additional pile of the same material around 20 to 25 feet high. Petitioner's Exhibits A, D, and E are photographs which provide an accurate representation of the site on the date of the inspection. Based on a visual inspection, but without having the benefit of his own laboratory analysis,2 Mr. Morgan concluded that the material was a solid waste made up of discarded industrial products. Under Department rules, the deposit of solid waste on such a site requires a waste facility management permit from the Department. A check of Department records indicated that Respondents do not hold a permit to operate a solid waste management facility. (DDD does hold a valid air pollution permit for grinding concrete.) During his inspection, Mr. Morgan also observed that the land adjacent to the filled area was wet, had a lower elevation than the compacted area, and contained small pockets of standing water. This was confirmed by photographs received in evidence as Petitioner's Exhibits D and E. A DDD employee who was present on the site during the inspection indicated that approximately 900 truck loads of the material had been transported to the site from Plant City after Mr. Stanton had "lost" a lease on the property on which the material had previously been placed. This was confirmed by Mr. Stanton who arrived at the site shortly after the inspection began, and who indicated that he intended to use the compacted wallboard as a sub-base (or foundation) for a wallboard recycling facility. A second site inspection by Mr. Morgan conducted on February 5, 2002, confirmed that the conditions (regarding the piles of fill material but not the standing water) at the site were unchanged from those found on October 8, 2001. On that visit, Mr. Morgan observed the site from his automobile but did not walk the property. Two other site visits were made, one on June 19, 2002, by other Department personnel. Except for a photograph (Petitioner's Exhibit C) dated June 19, 2002, which indicates the piles of material were still intact and had not been removed, the results of those inspections are not of record. Shortly after the initial inspection, the Department's Tampa District Office issued a warning letter to Mr. Stanton describing Mr. Morgan's observations and outlining the potential violations. The letter also invited Mr. Stanton to resolve the matter informally and to present a corrective action plan to mitigate the site. When the matter could not be resolved informally, the Department issued its Notice on October 10, 2002, alleging that Respondents had operated a solid waste facility without a permit and had deposited solid waste in an area prone to flooding. Even though the matter was not informally resolved, Mr. Stanton has cooperated with the Department in good faith throughout the regulatory process. The Material on the Site Invoices received in evidence reflect that the source of the deposited material was James Hardie Building Products in Plant City, Florida, and that the material was described on the invoices as "Dry Waste Material," Wet Waste Material," and "Foreign Material." James Hardie Building Products manufactures HardieBoard, which is a one-half to one-inch thick concrete formulated product used in the construction of homes and other buildings, and HardiePipe, which is used in road and bridge construction, culverts, storm sewers, and concrete pipes. The material being deposited was material used in the manufacture of HardieBoard. Mr. Stanton's long-range plans are to grind up, or recycle, the material (after all necessary permits, if any, are obtained) and then sell it to other persons, including cement manufacturing plants in the area, who will then use it for a variety of purposes, including subbase and base material, cement and concrete re-additive, and cement production. HardieBoard (as well as HardiePipe) is a variable mixture of Portland cement, water, fine silica sand, less than 10 percent cellulose (a non-toxic organic material commonly added to such products as ice cream, shampoo, baby diapers, and rayon clothing), and less than 10 percent of inert materials. The cellulose fibers are added to the concrete to avoid cracking and shrinkage and to reduce the weight of the product. Unlike concrete used for driveways and the like, HardiBoard does not have any large aggregate. Disposal of Solid Waste and Clean Debris Florida Administrative Code Rule 62-701.300(1)(a) prohibits the storing, processing, or disposing of solid waste except at a permitted solid waste management facility. In addition, no solid waste may be stored or disposed of "[i]n an area subject to frequent and periodic flooding unless flood protection measures are in place[,]" or "[i]n any natural or artificial body of water including ground water." Fla. Admin. Code R. 62-701.300(2)(d) and (e). These requirements form the basis for the charges in the Notice. Florida Administrative Code Rule 62-701.200(113) defines solid waste in relevant part as "discarded material, including solid, liquid, semi-solid, or contained gaseous material resulting from domestic, industrial, commercial, mining, agricultural, or governmental operations." Section 403.707(2)(f), Florida Statutes (2003), provides, however, that a permit is not required for "[t]he use of clean debris as fill material in any area." See also Fla. Admin. Code R. 62-701.220(2)(f). "Clean debris" is defined in Florida Administrative Code Rule 62-701.200(15) as: any solid waste which is virtually inert, which is not a pollution threat to ground water or surface waters, is not a fire hazard, and is likely to retain its physical and chemical structure under expected conditions of disposal or use. The term includes brick, glass, ceramics, and uncontaminated concrete including embedded pipe or steel. The term "virtually inert" is not defined by statute or rule. However, the parties agree that in order for a material to be "virtually inert," it must have no potential for leaking contaminants into the groundwater. In addition, if a deposited material releases contaminants into the groundwater thereby posing a threat to human health, it is considered a "threat to [groundwater]" within the meaning of the rule. The rule also provides that the material must not be a fire hazard. Finally, if a material decomposes over time after being used as fill, and releases contaminants into the groundwater, it is not "likely to retain its physical and chemical structure under expected conditions of disposal or use." Therefore, if a material has no potential for leaking contaminants into the groundwater, is not a threat to groundwater, is not a fire hazard, and is not likely to decompose over time, it constitutes clean debris and is exempt from the waste management facility permitting requirements. As noted above, Florida Administrative Code Rule 62- 701.200(15) identifies four materials that are considered to be clean debris: brick, glass, ceramics, and uncontaminated concrete. If a waste product is classified as uncontaminated concrete, it constitutes clean debris and may be used as fill without a permit from the Department. Further, clean debris may be deposited in an area subject to frequent or periodic flooding so long as flood protection measures are taken, or in a natural or artificial body of water so long as other appropriate permits (such as an Environmental Resource Permit) are obtained. Here, the central issue is whether the material deposited on Mr. Stanton's property is solid waste or clean debris. This issue turns on whether the material is virtually inert, is not a pollution threat to groundwater or surface waters, is not a fire hazard, and is likely to retain its physical and chemical structure under expected conditions of disposal or use. Assuming these criteria are satisfied, the material is exempt from Department permitting requirements for solid wastes. On this issue, the Department contends that the material is not virtually inert and is unlikely to retain its physical and chemical structure. Conversely, Respondents assert that the material is clean debris and falls within the category of uncontaminated concrete. Is the Deposited Material Clean Debris? In determining whether a material is virtually inert, or is a pollution threat to ground or surface waters, two extraction procedures have been sanctioned by the United States Environmental Protection Agency to assist in the measurement of the amount of contaminants that will leak from a material: the Toxicity Characteristic Leaching Procedure (TCLP) and the Synthetic Precipitation Leaching Procedure (SPLP). Under both procedures, the material being tested is ground up into small sand-size particles, mixed with an extraction fluid, and tumbled for 18 hours in a rotary agitator while the liquid solution extracts various metals that are found in the solids. The extracted liquid solution is then filtered and analyzed to determine the concentration of metals actually leached from the solids. Under state water drinking standards found in Table 1 of Florida Administrative Code Chapter 62-550, the maximum contaminant levels for chromium and barium (stated in milligrams per liter (mg/L)) are 0.1 mg/L and 2 mg/L, respectively. In reaching its conclusion that the fill material is a solid waste, the Department relied principally on certain tests of the material run by various laboratories between 1998 and 2000, which showed that the amount of chromium and barium leaking out of the product exceeded the State drinking water standards. See Petitioner's Exhibits K, L, M, and O. However, in every one of those tests, the laboratories used the TCLP, rather than the SPLC, which produced a worst case scenario. For the reasons stated below, the TCLP is not the appropriate procedure to be used for this purpose. The TCLP is the more aggressive of the two procedures, uses a much harsher solution than the SPLC, and generally leaches higher concentrations of metals. However, its principal purpose is to determine whether a material should be classified as a hazardous waste based on its leaching properties or characteristics. Using it to predict whether a material will leach into ground water is inappropriate because it will "leach things out in the laboratory that will never leach in the field." This is because it does not mimic conditions in the field and is "just not supposed to be used for this purpose." Therefore, TCLP leachate values should not be applied to drinking water standards. Conversely, the SPLC uses a less harsh solution during the preparation process, evaluates the potential for leaching metals into ground and surface waters, and is designed to provide a more realistic assessment of metal mobility under actual field conditions. In other words, the SPLC simulates what would happen if the sample were exposed to groundwater and rain to determine if under those conditions metals might leach into the water system below. Therefore, the SPLC is the more appropriate procedure to use here to determine whether the HardieBoard material will leach certain metals into the groundwater at levels that exceed State drinking water standards. Even various Department guidance documents provide that the SPLC (rather than the TCLP) should be used to determine if a material will leach metals into the ground water. See Respondents' Exhibits M, N, and O. Respondents' witness Foster collected three samples of HardieBoard deposited by Respondents at another site and submitted them to PPB Environmental Laboratories, Inc., in Gainesville, Florida, for a clinical analysis using the SPLC test. Those results, which have been accepted as being reliable,3 indicate that none of the leachate concentrations for arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver exceed (or even approach) the drinking water standards. Therefore, the material is virtually inert, and the groundwater quality will not be adversely impacted by use of this material as fill. The parties agree that the material is not a fire hazard. Prior to depositing the material, Mr. Stanton used a commercial waste reduction machine (a Smorcazy Bandit Beast 3680 Horizontal Trough Grinder) to grind or pulverize some of the material into fine particles. As noted earlier, a small amount of cellulose fibers are added to the product during the manufacturing process. The Department contends that after the grinding process occurs, these fibers will separate from the remaining fine particles and dissolve into the ground water. Because of this separation, the Department asserts that the material does not retain its physical or chemical structure after being deposited onto the property. Although cellulose fibers are added to the product during its preparation to strengthen the material (and have been added by cement manufacturers since the 1920s), they are distributed throughout the matrix in the material. This means that the fibers become "part and parcel of the mixture" and will not deteriorate, fall out, or leach out of the material even after routine grinding processes, such as that done by Respondents. As such, the cellulose is not biodegradable, and there is no concern that the cellulose will dissolve into the groundwater. Indeed, HardiePipe, which is used in the construction of culverts, storm sewers, and drainage pipes and has essentially the same constituents as HardieBoard, was approved by the Florida Department of Transportation in 2001 for use on State road and bridge projects. Therefore, it is found that the fill material will retain its physical and chemical structure after being deposited onto the ground. Expert testimony by Dr. McClellan established that the material meets the general definition of concrete, and because it is uncontaminated, it should properly be classified as uncontaminated concrete. As such, the material is clean debris and is not subject to the Department's solid waste management permitting requirements. Finally, the Department points out that the compressive strength (measured in pounds per square inch (PSI)) is much greater for concrete used in driveways than for HardiBoard (2500 PSI versus 20 to 30 PSI), and therefore Hardiboard is not a true concrete product. While the PSI values are indeed substantially different, the load bearing ratio or compressive strength of the material does not determine whether a material falls within the generic category of concrete. Water Issues As noted above, if a material is classified as clean debris, it may be deposited into an area prone to flooding or in a natural or artificial body of water, including groundwater (subject, of course, to other unrelated requirements or safeguards). There is no evidence that the filling occurred in a "natural or artificial water body," or directly into the groundwater. In addition, the evidence demonstrates that in October 2001, the ground next to the filled area had small pockets of standing water measuring no more than a few inches deep. However, when the inspection was made, and the photographs taken, Polk County was experiencing rather heavy rainfall, presumably due to the El Nino phenomenon. Whether these conditions (pockets of standing water) exist on the property only during the rainy season is not of record. Further, prior to the filling, Mr. Stanton contacted both the Southwest Florida Water Management District and the United States Geodetic Survey and he asserted, without contradiction, that neither agency indicated that his property was prone to flooding. In any event, even assuming that the area is subject to "frequent and periodic flooding," the permit requirements or other necessary safeguards, if any, associated with filling clean debris in such an area are not the subject of this proceeding. Investigative Costs A Department representative spent 66 hours investigating this matter for the Department. At a then-hourly rate of $18.54, this totals $1,223.64 in investigative costs. The reasonableness of this amount was not disputed by Respondents.
The Issue The issue in this case is whether Suncoast Concrete, Inc. (Suncoast), is entitled to Permit No. 194919-003-SO, to construct and operate a construction and demolition debris disposal facility (C & D facility) in Santa Rosa County, Florida.
Findings Of Fact Petitioners Lois and Wallis Mahute live within two miles of the proposed C & D facility. Petitioner Nathaniel Williams, Jr., resides less than one mile from the proposed facility. Suncoast is a Florida corporation and is the applicant for Permit No. 194919-003-SO. The site of the proposed C & D facility is already permitted by the Department as a disposal facility for land clearing debris. It is located on U. S. Highway 90, 1.9 miles east of State Road 87. The disposal area is 7.2 acres on a parcel of land that is 57.8 acres. Suncoast provided all of the information required by the Department for applications for C & D facilities, including geotechnical data, hydrologic data, and financial assurance for closure. The proposed permit includes numerous conditions, including the use of an impermeable liner, groundwater monitoring, stormwater controls, leachate collection and storage, and access control. The requirement for an impermeable liner is uncommon for C & D facilities and adds greater protection for groundwater. Issues Raised by Petitioners Petitioners expressed concern about groundwater contamination. The required liner is designed to prevent rainwater that might become contaminated after contact with the materials in the landfill from entering the groundwater. The proposed facility would be located over some existing land clearing debris. The existing debris is located on part of one side of the proposed landfill. Before the liner is installed, the base would be prepared by covering the area with six inches of compacted soil. After the liner is installed, two feet of clean soil is placed on top of the liner. The liner would be installed in a manner to prevent the liner from being punctured or torn. Groundwater monitoring is required so that any contamination that occurs will be detected and remediated. There are no potable water wells within 500 feet of the proposed facility. The nearest public water supply well is approximately 4,000 feet away. Petitioners presented the testimony of Kyle Holley, who expressed his views on hydrogeologic conditions in the area. Mr. Holley is not a geologist or hydrologist and was not competent to testify regarding the hydrogeologic conditions in the area. Petitioners expressed concern about odors, but presented no competent evidence that foul or unhealthy odors would be generated by the facility. The permit conditions that require a small working face and weekly cover with soil would minimize odors. Petitioners expressed concern about fires, partly because fires have occurred at other C & D facilities. The evidence shows that the requirements of the proposed permit, including the prohibition against burning and requirements to maintain a small working face and to cover with soil on a weekly basis, would minimize the possibility of fires at the facility. The facility must maintain access for fire trucks to the disposal area so that, if a fire occurs, it can be suppressed. Petitioners expressed concerns that the facility would not be safely closed in the event that Suncoast became bankrupt or otherwise ceased operations at the facility. The evidence shows that the financial assurance requirements of the proposed permit provide a means to close the facility in the event that Suncoast was unwilling or unable to close the facility. Petitioners expressed concerns about the “pattern of abuse” by landfill owners. However, Petitioners presented no evidence that Suncoast has shown a pattern of noncompliance, or that the landfills where these alleged abuses have occurred are similar to Suncoast’s proposed C & D landfill with respect to physical conditions and permit requirements. Suncoast provided reasonable assurance by a preponderance of the evidence that the facility, with the conditions in the permit, will comply with all applicable rule requirements regarding the protection of groundwater, odor and fire control, and proper closure of the facilities. In summary, Suncoast proved by a preponderance of the evidence that it has provided reasonable assurance that the proposed facility meets all regulatory criteria for entitlement to Permit No. 194919-003-SO.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department issue a final order granting Permit No. 194919-003-SO, subject to all the conditions set forth in the Department’s Notice of Intent to Issue, for the construction and operation of a construction and demolition debris disposal facility in Santa Rosa County, Florida.

The Issue The issue for consideration in this proceeding concerns whether the Petitioner is entitled to an on-site sewage disposal system permit or the grant of a variance from the rule by which that permit application was denied so as to be authorized to install an on-site sewage disposal system (septic tank system) for his property near the Suwannee River in Dixie County, Florida within the purview of Section 381.272, Florida Statutes and Chapter 10D-6, Florida Administrative Code.
Findings Of Fact The Petitioner, Desmond Harbroe, owns real property in Dixie County, Florida consisting of a lot described as lot 28 of Riverbend Estates. The lot in Riverbend Estates is located at "Hinton's Landing" on the west bank of the Suwannee River. The lot itself is located approximately 1500 feet west of the shoreline of the Suwannee River on a connected canal. The canal is characterized by high banks at the location of the lot and the lot is one of the highest lots in the subdivision, with overstory vegetation consisting of large pines and live oaks. The lot is gently sloping and characterized by well- drained soil consisting of sand down to a depth of 72 inches (a "slight limited" soil). The lot is approximately one and one quarter acres in size and was purchased May 29, 1976. The Petitioner contemplates constructing a single family residence on the lot and it does not presently contain an OSDS. The proposed residence would consist of a two bedroom dwelling with a heated or cooled area of approximately 1200 square feet. A dwelling of this size and type is equated in the standards in the Department's rules with production of 450 gallons per days (GPD) of sewage flow. Although no specific evidence of expected sewage is of record, there is no dispute regarding that figure. Herbert H. Raker is a registered land surveyor located at Box 626, Cross City, Florida 32628. Mr. Raker surveyed the subject lot and established a benchmark elevation of 13.72 feet above main sea level (MSL). That benchmark is six inches above the actual ground or grade level at the location of the benchmark. The site of the proposed installation itself is at an elevation of 13.22 feet above MSL. The ten-year flood elevation for the subject property is 15 feet above MSL. That elevation was established through data supplied by the Suwannee River Water Management District to the Petitioner and submitted to the Department in the application process. That information and the document upon which it is predicated is hearsay, but was not objected to at hearing and, in any event, constitutes an exception to the hearsay rule in the category of government records, compilations and reports for purposes of Section 90.803(8), Florida Statutes, and is, thus, admissable and accepted by the Hearing Officer. The subject property purchased by the Petitioner was for building a single family residence as described above. On December 12, 1989 the Petitioner received a letter from the Suwannee River Water Management District advising that there was no objection by the District to filling the lot in order to bring the surface grade level of that property to a sufficient height so as to comport with the "two year flood" elevation. The critical elevation in relation to the rules at issue however is the ten-year flood elevation. This advice from the Water Management District does not address the issue of filling the lot to bring it up to a level so that the bottom of the subject drain fill proposed would be above the ten-year flood elevation and thus comport with the rules at issue. In this connection, the property is located within the ten year flood plain based upon the evidence establishing that flood plain level to be at IS feet above MSL. The property is also located within the "regulatory floodway" of the Suwannee River. This is a geographical area closer in proximity to the actual free flowing portion of the river than is the boundary of the ten-year flood elevation demarcated area. The rule cited below provides that mounded systems requiring a placement of fill material, or construction above grade, will not be authorized in the regulatory floodway unless there is certification by registered engineers that the placement of fill or the structure placed would not increase the water surface elevation of the "base flood". That certification must be substantiated by data and the method of calculation used by the engineer must be provided. Here there is only a two and one half foot difference between the grade level of the property involved at the site of the proposed installation and the 15 foot ten-year flood elevation. Thus, as Mr. Harbroe indicates, given the overall size of his lot, it would be possible to fill the property to the proper grade level so that the bottom of the drain field trenches, when installed in the resulting mound, would be above the ten- year flood elevation. The Petitioner however supplied no detailed information about how such an alternative system might be installed and operate and, most particularly, did not supply the requisite engineering certification and information which might show that the installation of such a mounded system would not raise the level of the base flood. This might have been done, for instance, by establishing that a sufficient volume of fill could be removed from his property, elsewhere, to build the requisite mound and thereby not alter the surface elevation of the base flood. Such evidence is lacking in this proceeding however and cannot therefore serve as a basis for a grant of the permit, by means of illustrating an alternative system or approach for treating the sewage effluent which will comport with the rules. Pursuant to the authority of the statutes cited in the conclusions of law below and in related rules, lots platted before 1972 are accorded special consideration in determining whether to grant septic tank system permits (or variances). The Petitioner, however, did not adduce evidence of whether the subdivision known by the name "Riverbend Estates" of which his lot 28 is a part, is a platted subdivision at all, and did not establish that even if it is that it was platted and recorded before 1972. Thus no evidence has been adduced which will justify the special consideration provided for in the authority cited below. The grant of variances from the permitting rules involve the demonstration of hardship as a basic consideration. Hardship involves a demonstration that there is no reasonable means by which an on-site disposal system can be installed which will comply with the permitting rules, that is, impossibility of compliance is the bellwether for demonstration of hardship. It is also provided in the variance statute and rules cited below that the hardship may not be intentionally caused by the action of the applicant for the permit or variance himself. The Petitioner, having the burden of proof here, did not adduce direct evidence to establish that any hardship preventing compliance with the permitting rules was not intentionally caused by the Petitioner. However, the overall tenor of the Petitioner's testimony establishes inferentially, without doubt, that the hardship involving the Petitioner's impossibility of compliance with the permitting rules, given the presently prevailing grade level of his lot and installation site, was caused merely by his purchase of the property. He took no action involving that purchase to place himself in a position where he intentionally could claim a hardship situation and a justification of variance from the permitting rules and thus render himself legally capable of installing the subject system. He merely purchased the lot in good faith with, the intention of using it for a single family dwelling and did not intend by that mere act to place himself in a position to claim a hardship situation and thus circumvent the permitting rules. The similar use of the nearby lots in the subdivision for single family dwellings and which he was aware already had permitted septic tank type on-site disposal systems in place and operating led him to believe he could install a similar system. He was thus an innocent purchaser and did not intentionally create a hardship situation to thereby avoid compliance with permitting rules. In fact, however, the Petitioner has not truly established that he is in a hardship situation, that is, that he can not possibly comply with the permitting rules. This is because, by his own admission, he has sufficient land area on his lot to permit the "mounding" of an on-site disposal system. If this were accomplished it is quite likely that he could comply with the permitting rules and not require a variance, based upon a showing of hardship. The problem with this approach is that the Petitioner's proof fails because he did not adduce the requisite engineering certification and testimony justifying the grant of a permit based upon the building of the lot and mounding of the system. If this were accomplished in the future, it is quite likely that a permit could be granted for this lot. In a like vein, in terms of the variance issue portion of this proceeding, it has not been demonstrated by the Petitioner that no reasonable alternative exists for the treatment of the sewage involved nor has it been demonstrated that the discharge from the Petitioner's proposed sewage disposal system will not adversely affect the health of the applicant or other members of the public or significantly degrade the ground or surface waters. In this last regard, it although soil conditions prevailing at the proposed installation site and water table elevations beneath the surface of the property are appropriate as that relates to the requisite interval of "slight limited" soil between the bottom of drain field absorption beds and the water table elevation, the fact remains that these trenches or beds are beneath the ten-year flood elevation and thus pose the potential to degrade ground or surface testers. Thus the other requisite elements for establishment of entitlement to a variance from the permitting rules have not been made out by the Petitioner's proof. In fact, the Petitioner's proof establishes that a reasonable alternative may indeed exist for the treatment of the sewage involved with mounding of the system, since his grade elevation is only approximately 2.5 feet below the relevant flood elevation and unrefuted evidence shows that he has sufficient area on his lot to permit the mounding of the system with the requisite adjacent "buffer area". This constitutes a reasonable alternative which may comply with the permitting rules. Unfortunately, however, Petitioner's proof did not include the requisite engineering information and certification so that a recommendation for grant of the permit in the regulatory floodway can be made at this time. Having been denied his permit application on December 19, 1989 the Petitioner on March 5, 1989 applied for the subject variance referenced above. On April l9, 1990 the Petitioner was advised by the Respondent that it was useless to proceed with a variance application and that a formal administrative hearing should be sought before Division of Administrative Hearings instead. This is because of Executive Order 90-14 entered by the Governor, which incorporated the "Suwannee River Task Force" recommendation in evidence and, specifically, "recommendation #36." That portion of the report in effect recommended that on-site sewage disposal systems within the ten year flood plain area should be prohibited. The Department interpreted the effect of that executive order, incorporating the recommended prohibition from the task force report, to mean that such variances absolutely could not be granted by the Department, hence, its recommendation to the Petitioner and others similarly situated, that they should immediately seek a formal administrative hearing on the question, rather than expend time and expense pursuing the Department's internal variance procedure. The Department has thus in this in similar cases interpreted that executive order to create, and effect, a conclusive presumption that variances can not be granted in any case in which the installation site for the on- site sewage disposal system is at or beneath the ten-year flood elevation. In effect, therefore, it declines to exercise any discretion when confronted with variance request related to lots or property where the installation site for the proposed system occurs beneath the ten-year flood elevation.
Recommendation Having considered the foregoing findings of fact and conclusions of law, the evidence of record, the candor and demeanor of the witnesses and the pleadings and arguments of the parties, it is RECOMMENDED: That a final order be entered denying the Petitioner's application for an on-site sewage disposal permit and denying a variance from the statutory and rule requirements related to permitting for the reasons found and concluded above. DONE and ENTERED this 18th day of December, 1990, in Tallahassee, Florida. P.

The Issue Is Respondent, Watson Construction Company, Inc. (Watson), entitled to a general permit allowing it to operate a construction and demolition debris facility in Newberry, Alachua County, Florida?
Findings Of Fact DEP, in accordance with Chapter 403, Florida Statutes, is responsible for enhancing the beauty and quality of the environment; conservation and recycling of natural resources; prevention of the spread of disease and creation of nuisances; protection of the public health, safety and welfare; and provision for a coordinated statewide solid waste management program. It accomplishes these tasks, in part, by regulatory oversight directed to entities who operate solid waste facilities in Florida. That oversight includes permitting the activities by the facilities subject to compliance with statutory and rule requirements. Watson wishes to operate a solid waste facility in Newberry, Florida. In particular, Watson seeks to operate a C&D facility for off-site disposal of C&D debris to be placed where sand has been mined. Watson would pursue this enterprise by using a general permit, as allowed by DEP. Petitioner, City of Newberry (the City), is a political subdivision of the State of Florida. It opposes Watson's use of a general permit to conduct business as a C&D facility, based upon the belief that Watson has not demonstrated compliance with regulatory provisions that would allow Watson to use a general permit. Petitioner, Citizens for Watermelon Pond, Inc. (Citizens), is a corporation constituted of persons who oppose the use of the general permit for the same reasons expressed by the City. On July 21, 1994, Watson noticed DEP that it intended to use a general permit to operate a C&D facility. On July 29, 1994, a notice was published in the Gainesville Sun, a local newspaper, concerning the pendency of the use of a general permit to operate the C&D facility in Newberry, Florida. On August 12 and 16, 1994, the Petitioners filed petitions seeking an administrative hearing on the use of a general permit by Watson to operate the C & D facility. On August 19, 1994, DEP issued a Notice of Denial of the permission to use a general permit to operate the C&D facility. This permit request was under an arrangement between Watson and a co-applicant, Whitehurst. Following the Notice of Denial, no further action being requested by the applicants, DEP issued an order closing its file. In December 1994, in its name only, Watson resubmitted an application to use a general permit to operate the C&D facility in question. The level of consideration at that time was as a pre-application review. This was followed by a formal notice by Watson and application to use a general permit to operate the C&D facility. The formal application was filed on January 17, 1995. On January 24, 1995, notice was published in the Gainesville Sun concerning the more recent intention to use a general permit to operate the C&D facility. On February 6, 1995, Citizens filed a verified petition opposing the use of the general permit contemplated by the January 17, 1995 application. Two days later, the City filed a verified petition in opposition to the most recent request to use a general permit to operate the C&D facility. On February 15, 1995, DEP gave notice that it did not object to Watson's use of a general permit to operate the C&D facility. Watson's most recent request to use a general permit to operate a C&D facility was made on a form provided by DEP in accordance with Rule 62- 701.900(3), Florida Administrative Code. The application to use a general permit was sealed by a professional engineer. The legal description of the property in question is described in the application. It is located in Newberry, Alachua County, Florida. The site location for the proposed C&D facility is one and one-eighth mile south of Southwest 46th Avenue on the east side of County Road 337 in Newberry, Florida. Documentation has been provided which identifies the legal authorization to use the property as a C&D facility. The C&D facility has a planned active life of 50 years. It is intended that the sand that is excavated will be replaced by C&D debris at a similar grade. The mailing address and telephone number of the C&D owner and operator is identified. Watson is the owner/operator. There are 158 acres within the proposed site. Approximately 143 acres would be used in the C&D operation by mining sand as a prelude to recontouring the site by placing the C&D debris. It is intended to excavate tan sand and silty sand to a depth of 20-30 feet. Although Watson anticipates excavating sand to a depth of 30 feet, bore hole data reveals the existence of sand below that depth. Watson does not intend to excavate below 62 feet mean sea level (MSL). In any event, it is not the intention to excavate below the interface of the sand and underlying sandy clays. Once the sand has been excavated, it is anticipated that the bottom of the C&D disposal area will be approximately 15 feet above the piezometric water table associated with the Floridan Aquifer, according to the applicant. The proposed site is located in rolling terrain, whose elevations range from approximately 80 feet MSL to 100 feet MSL. To support the use of a general permit, Watson has provided a site plan with a scale not greater than 200 feet to the inch, which identifies the project location, with proposed disposal areas, total acreage of the site and of the proposed disposal area, and other relevant features that exist on or within 500 feet of the site. The property boundaries are identified. The site would be fenced. Access to the facility would be controlled by a locked gate on County Road 337. The gate would be open during daily operations. The site does not contain surface water. There being no surface water, the C&D facility does not require a surface water management permit from the Suwannee River Water Management District. The site does not present a problem with stormwater runoff. A potable well is located within 500 feet of the property boundary. However, placement of C&D debris would be offset by a 500-foot buffer from the well. Wetlands are located 2,100 feet from the southern edge of the proposed site in the eastern part of the adjacent Whitehurst parcel. Within 3,000 feet of the proposed site is an old phosphate mining pit on the Whitehurst parcel, and 6,200 feet from the proposed site is the northern-most unnamed pond associated with Watermelon Pond. The site is not susceptible to flooding at present. The sand mined at the proposed site would be used to build roads and for foundations for houses and other buildings. Clay removed from the building sites to make room for the sand would be placed in the C&D facility. The material that is removed from building sites and substituted by sand fill is clay with a high shrink and swell factor. That material, together with flint rocks, tree limbs and stumps, would be transported to the C&D facility by Watson's dump trucks. At present, Watson has 20 dump trucks. The dump trucks hold 20 yards each. In addition to those materials removed from Watson job sites by dump trucks, Watson has approximately 36 roll-off dumpsters which hold 20 yards each. Two Watson trucks are available to transport the roll-off dumpsters to the C&D facility. The roll-off dumpsters are placed on construction sites, not exclusively Watson's, and construction materials not used in the building process would be placed in the roll-off dumpsters for disposal at the C&D facility. Approximately 70 percent of the fill material to be placed in the C&D facility would be unsuitable soils, trees, limbs and stumps. The remaining material would be the C&D debris from construction at sites where the dumpsters have been placed. The dump trucks that hold the clay, limbs and stumps would be loaded by Watson employees, who can control what is placed in the trucks. Watson would not control what is placed in the roll-off dumpsters at other construction sites. The Watson dump trucks from job sites directly related to its activities would arrive at the C&D facility and dump their loads for compaction. Those loads would not be spotted for unsuitable fill materials. By contrast, the roll-off dumpsters would be examined at the construction site by the Watson driver. If the driver discovers excessive amounts of material not classified for C&D fill, contact would be made with the Watson office and the material taken to the Alachua County landfill for disposal. If the driver picks up the dumpster at the construction site and there are limited amounts of material not suitable for disposition at the C&D facility, the dumpster would be taken to the C&D facility. The material would be spread out, and a spotter would segregate materials that are not suitable for C&D fill. The unsuitable material would be placed in temporary containers at the disposal site and transported off-site to a permitted landfill or other appropriate facility. Some material brought to the landfill would be recycled. Woods, such as pine or hardwood would be recycled. The limbs and stumps would be placed in the pit as fill. Copper, aluminum, steel, iron, and any other metal would be recycled. The metals would be sold to a scrap-iron facility. An employee at the landfill would keep the money earned from recycling. Metal embedded in broken concrete would be used as fill. The C&D facility would be operated by two persons: one, a loader/operator who loads the dump trucks with the sand that is being excavated; the second individual, a bulldozer operator who pushes the dump truck loads of clay, limbs, and stumps into the fill area and spreads them. He would also spot the roll-off dumpsters and segregate the fill material from unsuitable material. The sorted construction material to be used as fill would be pushed into the working face of the pit, where the tree limbs, stumps and clay would have also been placed. It is anticipated that six to ten roll-off dumpsters with C&D material would be brought to the C&D facility on a daily basis. The amount of unsuitable material that must be sorted from the dumpsters would vary with the individual loads. Watson operates an existing C&D facility in Alachua County, Florida. The proposed C&D facility would be similar in its operation. Based upon the experience in the existing facility, there is no indication that the proposed C&D facility could not be adequately operated by two employees, taking into account the need to segregate unsuitable material before filling. The spotter would receive verbal training concerning his duties. The training provided the spotter is on-site training. He would be reminded once a week of the need to do an adequate job of looking for unsuitable materials. At present, Alachua County inspects the existing C&D facility on a weekly basis and reminds the spotter at that facility what is appropriate for placement and what is not. The expectation is that the same function would be performed at the proposed facility. If sinkholes are encountered in excavating the sand, the equipment operator would contact the Watson office. In turn, Watson would contact its consulting engineer to address the problem, to include placing a plug or cap to repair the breach caused by the sinkhole. In the event that limerock is encountered in the excavation, a clay cap will be placed to prohibit leachate from flowing into the ground water. Areas where limerock is located at higher elevations and not covered by clay present the greatest risk for sinkhole formation. The period between excavation and fill will be approximately two years, leaving the site exposed at the level of excavation before fill is replaced. When the site is closed, the front-end loader operator and bulldozer operator will spread 24 inches of soil as a cap and grade the site in preparation for planting of pine trees. The soil material would be constituted as six inches of top soil suitable for planting pine trees. The remaining 18 inches would contain clay with high shrink/swell properties. The planting of pine trees would be done through a contract forester. The equipment operated at the facility would employ approved muffler systems. Odor generated by the facility is not anticipated to be a problem, in that household garbage, if found, would only be temporarily maintained, pending placement in an appropriate landfill. The site will be examined on a weekly basis to remove blown "litter". Proper provision is made for maintenance of slopes and compaction of fill material as it is placed. Through the application process noticing DEP that Watson intends to use a general permit to operate its C&D facility, DEP has been informed of the location of the proposed site. DEP would have permission to inspect the site during normal business hours. In response to Rule 62-701.420, Florida Administrative Code, Watson conducted a geotechnical investigation and prepared a report to support the application for a general permit. In support of the application Kenneth J. Hill, P.E. investigated the subsurface conditions at the proposed site through drilling activities. The drilling was done at the site and adjacent to the site. In May, 1995, Douglas L. Smith, Ph.D., P.G., conducted an electrical resistivity study (ER) at the site to investigate the subsurface conditions. Thomas H. Patton, Ph.D., P.G. and Charles Swallows, P.E. assisted in the investigation of the subsurface conditions at the site. Ralph E. Eng, P.E., signed and sealed the application for general permit for the proposed C&D facility. In rendering a report following his investigation of the subsurface conditions, Mr. Hill signed and sealed the report and supporting documentation. Likewise, Dr. Smith signed and sealed the report and supporting documentation associated with the ER study, together with Anthony F. Randazzo, Ph.D., P.G. The contribution by Dr. Patton and Mr. Swallows to the geotechnical investigation did not include signing and sealing a report and documentation. Nonetheless, Dr. Patton and Mr. Swallows, when testifying concerning the permit request, as with other professional witnesses, were found qualified to offer testimony consistent with their professional credentials and factual knowledge. 1/ A foundation analysis to determine the ability of the foundation to support the loads and stresses imposed by the fill material revealed that the weight of the construction debris was approximately 70 pounds per cubic foot, whereas the weight of the existing sand to be excavated is approximately 100 pounds per cubic foot. Thus, the placement of fill material following excavation would impose less stress on the subsurface than before. No significant settlement of the fill materials is expected to occur, resulting from its weight. The nature and fate of leachate promoted by the placement of fill at the site, in an environmental susceptible to bio-chemical and physical influences in transport through the subsurface, has the potential to adversely impact ground water. Those impacts could possibly cause violations of water- quality standards, ground-water standards, and drinking-water standards. These issues are considered based upon facts associated with the imperatives which must be properly addressed through the geotechnical investigation. That process anticipates gaining an understanding of subsurface conditions, to include the soil stratigraphy and ground-water table conditions. The ground-water table conditions involves estimations of the average and maximum high ground-water table. The geotechnical investigation should also explore the possibility of and address the existence of any sinkholes on the site. No specific testimony was given concerning the degree to which leachate, when present in the ground water at the Floridan Aquifer, might promote water-quality violations. Leachate properties and constituents were described in general terms of water-quality considerations, for example, hardness, nitrates, nitrites, alkalinity, presence of ammonia, chlorides, iron manganese, phenols, barium, arsenic, cadmium, lead, mercury, zinc, TDS and sulfates, urea formaldehyde, plaster, creosote, glues, and mastic hardeners. The evidence presented concerning the parameters for water quality did include a reference to barium, ranging from .5UG/L to 8UG/L in basically similar circumstances. The fill material can influence the natural PH by creating acidic conditions causing the PH to fall from a neutral 7.0 to 5.5 to 6.5. The process that takes place over time with the fill material also releases gases, such as methane, hydrogensulphide, and carbon dioxide. Rainwater falling on the ground's surface forms the basis for transporting the leachate through the subsurface. Only the Floridan Aquifer is potentially at risk, there being no surface water bodies or surficial aquifer at the site. Taking into account rainfall disposition by evapotranspiration, storm- water runoff, and subsurface infiltration, without certainty as to the amounts in those processes, it can be said that a significant amount of rainfall is available through infiltration to recharge the Floridan Aquifer and to transport leachate promoted by the fill. This is borne out by the absence of surface water bodies and a surficial aquifer on the site. To gain basic information concerning the subsurface conditions, Watson had 14 standard penetration test borings conducted by Mr. Hill and his firm. Those borings were advanced to depths of 35-72 feet. Additionally, three auger borings were performed to a depth of 40-50 feet. The auger borings were at sites A-1, A-2, and A-3, performed on April 17, 1993. In July of 1993, standard penetration test borings were performed at sites B-1, B-2, B-3, and B-4. In April of 1994, standard penetration test borings were performed at sites B-5, B-6, B-7, and B-8. In September of 1994, standard penetration test borings were performed at sites B-9, B-10, B-11, B-12, B-13, and B-14. The borings that were performed at the proposed site were at B-2, B-5, B-6, B-9, B-10, and B-14, for a total of six borings. The other borings were performed on the adjacent parcel. The borings at the proposed site were widely dispersed over the 143 acres contemplated for excavation and fill. The borings on the adjacent parcel, referred to as the Whitehurst parcel, were widely dispersed over 475 acres. Logs of the soil borings were prepared depicting the findings in the subsurface. The soil stratigraphy found in the borings was varied with sand, clayey sand, sandy clay and limerock present in some but not all borings. The sands that have been described are Aeolian. The sands are remnants of an ancient coastal dune system. Soil permeability tests were conducted on a limited basis at boring B- 9 at a 25-foot sample depth. The tan and orange clayey sand described had a co- efficient for permeability of 1x10-6. That sample and others described were obtained through a split-spoon. At B-12, at 35 feet, tan and orange clayey sand was found with a co-efficient for permeability of 2.6x10-8. At B-13, at 30 feet, tan and orange clayey sand was found and tested as 2.0x10-8 for the co- efficient for permeability. At B-14, at 30 feet, tan and orange sandy clay was found with a co-efficient for permeability of 9.6x10-9. In describing the soils, sieve analysis was not performed to more precisely classify the sediments encountered. This description of the strata is by appearance and texture. The clayey sand and sandy clay found in the borings retard discharge of the leachate to the ground water in the Floridan Aquifer based upon the permeability in those soils. Generally stated, the tan sands described have a co-efficient for permeability of 10-1 to 10-4. These sands are highly permeable, presenting an easy opportunity to convey the leachate contained in the infiltrating rainwater. Anomalous findings concerning soil permeability are shown at B-4, an off-site location, which portrays only sand in the boring. Also, B-9, which was drilled four to five feet east of a known sinkhole at the site is noteworthy in that the boring log describes tan and orange sandy clay, with trace limerock below 30 feet. This is in contrast to the field notation by the driller of the "p" for push and drilling rod "free fall" from 38 feet BLS to 42.5 feet BLS before encountering limerock, connoting a possible cavity in the 38-foot BLS to 42.5-foot BLS region. The karst feature that is located in the area where boring B-9 was conducted will be surveyed and marked with fence posts prior to excavation. No excavation will be conducted within 200 feet of that site. In addition to the phenomenon at the B-9 boring area, sinkholes at the surface were observed one-half to three-quarters of a mile northeast of the site. Sinkholes can occur when the placement of fill changes the hydraulics and loading in a karst environment. Finally, at B-6, limerock was encountered above the 46.9 feet MSL regional piezometric surface of the Floridan Aquifer. That limerock is considered part of the aquifer system. The head pressure at that location was not sufficient to force the ground water from the Floridan Aquifer. The more typical experience was as shown in B-5, where the surface of the limerock was lower than the regional piezometric surface. In B-5, ground water was not encountered until the clayey layer was breached and water rose in the drill hole. On occasions, such as the experience in B-5, there was an indication that Artesian conditions existed at those places. At the locations where the Artesian conditions were experienced, the Floridan Aquifer is confined. At B-6, where the limestone rises higher than the regional piezometric surface, the Floridan Aquifer is not confined. The bore hole at B-2 was terminated before breaching the clayey layer, and ground water was not encountered. Watson's consultant Hill considered that the ground-water table was found within the Floridan Aquifer at the site whose regional potentiometric surface was 46.9 MSL. He perceived that the findings showed ground water at 45 feet MSL constituting the average for the site. Watson estimated that the "seasonal high" ground-water table at the site was 48 feet MSL. The term "seasonal high" is equated to maximum high. Watson claims that the fluctuation in the ground-water table would be only a few feet. This would mean that the 45 feet MSL from bore hole data would represent not only the average across the site but the average value at the site at any point in time during the year. Watson makes this assertion notwithstanding that the borings were made over two years during different seasons. The basis for the estimate of maximum high ground-water table is not evident. In Dr. Patton's remarks in the application, there is a reference to the fact that the lowest encountered elevation for the Floridan Aquifer was 45 feet MSL and the highest was 55 feet MSL, making the average 50 feet MSL. This runs contrary to the remarks by Hill in which Hill said the elevation in the region was 46.9, the elevation detected was 45, and that the seasonal high would be 48. The only borings that were made in which the log reflects the MSL elevation and the boring depth are borings that were conducted in April 1994. On that date, the boring depth at which ground water was encountered varied from 37-43 feet and the MSL depth varied from 39-47 feet. If only the information for B-5 and B-6 on the site proper is used, those two data points associated with the borings on April 1994 reveal ground water at an excavation depth of 37 feet and between 45-47 feet MSL, respectively. Overall, without reference to MSL, the depths at which the ground water was encountered in the borings varied from 19-44 feet, if encountered. Although it is not shown in the boring log what the relationship is to MSL, at B-9, water was found at a drilling depth of 38 feet; at B-10, at a depth of 36 and one-half feet; at B-2, no water had been encountered at a drilling depth of 50 feet; at B-14, no water had been encountered at a drilling depth of 35 feet; at B-1, water was encountered at a level of 44 feet; at B-3, water had not been encountered at the concluding depth of 50 feet; at B-4, water had not been encountered at the concluding depth of 50 feet; at B-11, water was encountered at a drilling depth of 31 and one-half feet; at B-12, water was encountered at a drilling depth of 19 feet; at B-13, water was encountered at a drilling depth of 21 and one-half feet. Where elevations were measured for the water table in the bore holes, the holes were left open until the drillings had been concluded. Then the measurements were made. In this project, the consultant did not equilibrate the ground-water table by the traditional method of leaving a piezometer in the bore hole to maintain its integrity for a day before making the measurement. Watson has not provided sufficient information and explanation to determine a proper estimate of the average and maximum high ground-water table across the site. Returning to the ER investigation, it involved 39 soundings, which is roughly equivalent to drilling bore holes. The sounding profiles were determined through Wenner-Array Sounding and Lee-Directional Equipment. This technique involves the passing of an electrical current underground and measuring its resistance to flow. The expectation is that earth materials, for example, clay, sand, limestone, and cavities will resist the flow of electrical current differently. Substantially greater contrast in the degree of resistance, anomalies, is used to identify and locate earth materials, as well as the presence and shape of cavities. The sounding measurements reveal two- dimensional detail below the surface at progressively-greater depths. Lee- Directional measurements determine the direction of higher or lower resistivity along the survey line. While in the field, electrodes are placed in the ground at equal distances from one another. After a measurement, this distance is increased in an orderly fashion. The greater distance between the electrodes, the greater the depth of penetration. The ER equipment's electrical current has the capacity to penetrate through clay and into lower features in the subsurface. Subsurface from depths five to 100 feet were examined in this study. Within the 39 groundings surveyed, various soils were encountered. Generally, a thick cover of unconsolidated sand was found overlying clayey sand, with a clay layer varying in thickness and limestone found in some soundings, but not others. Where limestone was detected, it was at deeper levels in the southwestern part of the site. Because ER cannot distinguish between clayey sand and sandy clay, the area where those soils are found is referred to in the report as a thinner clayey sand layer. Also, in some places the upper surface of limestone has suffered weathering or deterioration and may appear as the lower part of the clay unit in terms of its electrical properties. The general portrayal in the ER study concerning the soil stratigraphy, wherein reference is made to dry sand up to 30 feet in thickness overlying a thinner clayey sand layer, approximately 10 feet in thickness, overlying a relatively thick clay layer from 10-60 feet and then limestone, does not coincide with the complexity in the stratigraphy found in the soil borings. In the ER study, at stations 8 and 10, voids were encountered. The nature of those voids is unexplained by this investigative process. At station 8, the void was found at approximately 100 feet deep. At station 10, the voids were at 50 feet and 100 feet deep. At station 14, anomalous findings were explained as the placement of fill and organic material during land-clearing operations. The suggestion in the written report, which summarizes the findings in the ER investigation, that a water table was encountered at approximately 40 feet deep, coinciding with the top of the clay layer, is contrary to the findings in the soil borings. To the extent that finding is intended to suggest that there is a perched water table or surficial aquifer above the clay layer, that view is contrary to other evidence adduced at hearing and is rejected. Like the soil borings, the ER soundings examined very discreet areas, but revealed less discreet information. This investigative process is not designed by itself to resolve disputes concerning the character of the subsurface, taking into account statutory and rule requirements for issuing a general permit. To portray the subsurface conditions, in June 1995, Petitioners undertook another basic study by employing ground-penetrating radar (GPR) to reveal the subsurface conditions. Again, GPR, like ER, affords limited insight into the conditions in the subsurface. More precise information than is revealed in the results from the GPR study would be needed to understand the subsurface conditions. GPR is comprised of several pieces of equipment that are connected with cables and a power source. This equipment is mobile. It uses a transmitter and receiver antenna that essentially glides along the ground surface. A signal is emitted through the transmitter. It perpetrates into the ground. It is reflected off materials of different electrical properties back to the receiving antenna and charted. The record that is made is continuous. Unlike ER, GPR is capable of detecting small anomalies in the subsurface. In employing the equipment in this investigation, Petitioners' consultant was looking for either stratigraphic or water-table reflectors and anomalous conditions. The experience at this site was comparable to the experience at other sites in gaining an understanding of how geologic materials are deposited. The GPR investigation covered approximately 10 percent of the site. Four lines were traversed east to west. Two lines were traversed north to south, and two other lines were traversed on a diagonal. GPR will not significantly penetrate clay. Its ability to penetrate is dependent in some measure upon the nature of the clay unit encountered. However, GPR reveals contrasts in the conductivity of clay, when compared to the overlying sand. The greater the contrast, the greater the reflection event. In this connection, the presence of moisture can slow or prohibit the electromagnetic energy generated by GPR. The GPR study revealed a substantial number of subsurface anomalies that might be indicative of possible access for leachate generated by the placement of fill to enter the Floridan Aquifer. These anomalies might represent sand columns and cover subsidence sinkholes. Any sinkholes on the site would be expected to be "cover subsidence"- type sinkholes. Those sinkholes occur through a process in which overlying strata slowly subsides into the sub-adjacent karst feature, rather than suddenly collapsing. Sinkholes develop rarely, but pose more risk of development in areas where sinkholes have occurred previously. Sinkholes are not always seen at the land surface. Sinkholes can present a risk to ground water in the aquifer in view of solution cavities found in the limestone which is part of the aquifer, thus allowing leachate to flow through the cavities into the ground water. Some anomalies found in the GPR study were more significant. One that was observed in the third traverse was 100 feet wide by 80-90 feet deep. There is an indication that this area might be filled with sands, creating a more ready access to the lower subsurface than would be expected with other soils. Another anomaly discovered was 200-300 feet long and 400-500 feet wide, approximately 50 feet below the surface. Overall subsurface conditions are not readily understood. Watson, through its consultant, suggests that the site is part of the Newberry Sand Hills region of the Brooksville Ridge system. As such, karst activity has proceeded in a slower manner than other places in Alachua County, with no presently active karst conditions. In opposition, Petitioners assert that the site is part of the Brooksville Ridge System, which is an internally-drained area of karst-dominated highly fractured terrain, according to its consultants. If Petitioners are correct, those circumstances lead to solutioning of the limestone and are not indicative of area of continuous impermeable clay layers found at the site as part of the Hawthorne formation that Watson's consultant surmises. The exact nature of the site concerning factors that must be considered in this permit application have not been adequately resolved in this record. While it is sufficiently evident that the Floridan Aquifer is not confined, it is unclear whether the circumstances at the site present unacceptable risks to the ground water, in view of existing subsurface conditions. From the record, the proper manner to resolve the issue would be to perform more soil borings on the site proper to identify the subsurface conditions concerning soil stratigraphy and ground-water location.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered which denies Watson the use of a general permit to operate the proposed C&D facility. DONE AND ENTERED this 7th day of August, 1996, in Tallahassee, Florida. CHARLES C. ADAMS, Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 7th day of August, 1996.
The Issue The ultimate issue to be resolved in this proceeding is whether the Department of Environmental Regulation should issue a permit to Broward County authorizing construction of the proposed Cell 14 extension of the Broward County landfill located in the Town of Davie, Florida. Broward County and the Department of Environmental Regulation contend that Broward County has provided reasonable assurance that the proposed facility will meet the requirements of the Department's rules and regulations and not cause pollution in contravention of the Department's standards. The Town of Davie contends that the proposed facility will not meet the Department's requirements and will result in pollution in contravention of the Department's standards.
Findings Of Fact Broward County presently operates a landfill known as the Davie Landfill on a tract of land comprising 200 acres within the Town of Davie, Broward County, Florida. The existing sanitary landfill includes 13 cells which cover approximately 20 acres on the northeastern portion of the site. The landfill had an original design elevation of50 feet. The Department of Environmental Regulation, in a separate permitting proceeding, has authorized an increase to the height of the existing landfill to 90 feet. The permit authorizing increasing the height of the existing landfill has been challenged by the Town of Davie and is the subject of a separate proceeding before the Division of Administrative Hearings. The site which includes the landfill also has a sludge lagoon and trash landfill located in close proximity to the sanitary landfill. The sludge lagoon was used until sometime in 1981 for disposal of septic tank clean-out, sludges, grease trap waste, and wastewater treatments. The trash landfill was designed primarily for disposal of yard trash. The existing landfill has vertical side slopes of 3.5 to l. In other words, the height of the landfill increases along sides by i foot for every 3.5 feet traveled horizontally. Through this application, Broward County is seeking approval to expand its sanitary landfill by adding a proposed Cell 14. Cell 14 would constitute a Class I landfill since it will receive in excess of 20 tons of solid waste per day. The proposed Cell 14 would be constructed along the existing western face of Cells 1 through 13. It would ultimately be constructed to a height of 90 feet and would be capped with an impervious substance. The western side slope of the proposed cell would also be 3.5 to 1. Cell 14 would cover approximately 11 acres, bringing the total size of the sanitary landfill to just over 30 acres. With Cell 14, the sanitary landfill would continue to operate until approximately 1986. Containing leachate and preventing it from entering surface or ground waters is a most important consideration in determining whether to permit sanitary landfills. Leachate is water that has passed through refuse and been contaminated by the refuse. If significant amounts of leachate from Cell 14 enters into surface and ground waters, violations of the Department's water quality standards would be likely. Several features have been designed into Cell 14 to prevent introduction of leachate into surface and ground waters. The base of the cell would have a high density polyethylene liner to prevent percolation of Leachate that collects at the bottom of the cell into groundwater. A leachate collection system consisting of pipes and manholes has been devised. As leachate collects at the base of the cell, it will be dumped into tank trucks and carried to nearby wastewater disposal plants where it will be treated. A stormwater collection system has been designed so that initial stormwater runoff will be pumped to the leachate collection system and tested. If significant pollutants are contained in the stormwater runoff, it can continue to be pumped into the leachate collection system and ultimately removed to off-site treatment plants. If there are not significant pollutants in the runoff, runoff will be collected in a swale system and ultimately percolate into groundwater. Water that leaves the site in this manner is not likely to cause violations of Department of Environmental Regulation standards either in surface or ground waters. Numerous technological advances have occurred since Cells 1 through 13 of the Davie Landfill were designed and constructed. These cells have a designed-in leachate collection system. The system presently functions adequately, except that the liners under the earlier cells appear to be breaking down. It is apparent that the liner under Cells 1 through 4 has deteriorated to the extent that all leachate from these cells is not collected in the leachate collection system, but enters the groundwater below the landfill. Leachate from a landfill of this sort and magnitude that enters groundwater is likely to cause pollution in violation of the Department's standards. Leachate is presently entering the groundwater from Cells 1 through 4. The nature of the liner under the remaining original cells is not known. It is thought to be made of asphalt. Many forms of asphalt, obviously including the kind that was used to line Cells 1 through 4, are not capable of containing Leachate for an extended period of time. If the liner breaks down, the leachate collection system under all of the original cells will no longer function, and leachate will enter the groundwater, causing violations of Department of Environmental Regulation standards. There will not be an impervious liner between the existing cells of the Davie Landfill and the proposed Cell 14. It has been estimated that the cost of such a liner would be prohibitive. There will be limerock placed between the existing cells and the proposed cell; however, limerock is permeable. Some Leachate from Cell 14 will seep into the existing cells. Some of the leachate from the proposed Cell 14 that enters the existing Cells 1 through 4 will find its way into groundwater under the landfill. Leachate that enters the remaining cells will also find its way into groundwater if the liner under these cells breaks down as the liner under Cells 1 through 4 has broken down. If Leachate from the proposed Cell 14 enters groundwater under the site of the landfill, it is likely to cause pollution in violation of Department of Environmental Regulation standards. Groundwater in the area of the Davie Landfill flows generally from the northwest to the southeast. Some of the groundwater from the site of the sanitary landfill is likely to find its way into a canal which is located just to the south of the site. this is the C-11 Canal. If leachate from the proposed Cell 14 enters groundwater under the site of the landfill, it is likely to ultimately cause violations of Department of Environmental Regulation standards in the C-11 Canal. Except for the fact that the liners under the existing cells of the sanitary landfill are subject to deterioration, the leachate collection system can function appropriately. The leachate collection system for the proposed Cell 14 can also function without allowing introduction of leachate into surface and ground waters. The leachate collection systems utilize pipes that are presently buried under the existing landfill and will be further buried by the construction of Cell 14. The pipes that are presently being used, and are proposed to be used, are designed to withstand pressure greater than would be imposed on them. Furthermore, they are being placed in such a manner (surrounded by rock and utilizing ball joints) as to reduce the pressure imposed upon them. It is possible that one of the pipes could break and that leachate could thus escape from the Leachate collection system. This possibility is not a likely one, however, given the design parameters of the pipes and the nature of their installation. The fact that the leachate collection system for existing cells of the Davie Landfill would be buried under the proposed Cell 14 does not raise a significant danger that the system will break down. Again, the design parameters of the pipes and the nature of their installation render breakage unlikely. The sludge pit that is located just to the southwest of the sanitary landfill and the trash landfill that is located just to the south of the sanitary landfill offer potentially severe threats to the integrity of ground and surface waters on and off of the site. The sludge pit is a hazardous waste site. The trash landfill is not designed to prevent substances placed on the landfill from percolating into groundwater. It does not appear that construction of the proposed Cell 14 addition to the sanitary landfill would increase the risk of pollution that the sludge pit and trash landfill present. It does not appear that construction of the proposed Cell 14 would cause significant additional surface or ground water flows that would increase the risk of material from the sludge pit or the trash landfill from entering surface or ground waters. The applicant has failed to provide reasonable assurance that its proposed addition to the Davie Landfill will not result in violations of Department of Environmental Regulation standards contained in Chapters 17-3, 17- 4, and 17-7, Florida Administrative Code. While the proposed cell has been designed with appropriate liners and with an appropriate leachate collection system, its location abutting an existing landfill which does not have an adequate liner preventing percolation of leachate into groundwater increases the risk of that occurring. It appears that the only means of preventing or reducing that risk is either to close off the existing cells, or to place a liner between the existing cells and any addition in order to prevent flows of Leachate from new landfill activities into the existing cells.
The Issue The manner and extent to which the criteria of Rule 17-7.07, F.A.C., entitled "Dump Closing" may be required by Respondent with respect to the Town of Surfside Dump.
Findings Of Fact In 1949, Petitioner purchased approximately 378.8 acres of land located in the northwest section of Miami, Florida. It sold approximately 250 acres of the eastern portion in 1959 to County Line Development Company. Petitioner utilized the remaining land as a solid waste disposal facility known as the "Surfside Dump," and in early 1955, other municipalities in North Dade and South Broward Counties also began using the facility for waste disposal. Originally, "white" goods, rubbish, garden trash, vehicle bodies, and tires were disposed of at the site, in addition to domestic garbage. Somewhat later, the receipt of vehicle bodies and other oversize waste was discontinued. For a number of years, the basic procedure for disposal was to dump the refuse into open trenches where it was compacted by bulldozers and covered with a layer of locally available material. The dump presently is bounded by Northwest 215th Street on the north, Northwest 47th Avenue on the west, Snake Creek Canal on the south, and the land previously conveyed to County Line Development Company on the east. A large portion of the dump area on the west side has not been used since 1972. (Petitioner's Exhibits 1, 3) Inspections of the dump conducted by Department of Pollution Control representatives at various times from 1973 through 1975 revealed that waste was not being covered in a satisfactory manner in that trenches were dug from old refuse, raw garbage was pushed into the water-filled trenches and then recovered with the old refuse. In 1975, the County Line Land Company filed suit against the Petitioner in the Dade County Circuit Court complaining that the dump constituted a public and private nuisance and was being operated in violation of the county code relating to uncovered garbage, Chapter 10D-12 of the Rules of the Department of Health and Rehabilitative Services governing disposal of garbage, and Chapter 17-7 of the Department of Pollution Control pertaining to regulation of solid waste. The Circuit Court found that the dump adversely affected the health and welfare of the surrounding area, and that although the facility was being used for revenue purposes by Petitioner, the conditions existing there had not been improved over the years. It therefore enjoined Petitioner from accepting further refuse at the site commencing June 30, 1976, except from within its own boundaries. It further gave Petitioner until August 1, 1976, to show that it had complied with Chapter 17-7 of the rules of Respondent or that it had received a temporary operating permit under the pertinent regulations. The decision was affirmed by the First District of Appeal on January 4, 1977. State regulations in effect since 1962 have required sanitary landfills to dispose of garbage in compacted layers with not less than a daily six inches of cover material and a final covering of two feet of compacted earth unless otherwise approved by the regulating state agency. (Rule 170C-10.07, State Board of Health; Rule 10D-12.07, Department of Health and Rehabilitative Services)(Respondent's Exhibits 1-3) On February 4, 1975, the Department of Pollution Control sent Petitioner a Letter of Notice advising that the Surfside Dump was in violation of various provisions of Chapter 403, Florida Statutes, and Chapter 17-7, Florida Administrative Code, by not applying for a temporary operation permit. By letter of March 28, 1975, that Department sent a Warning Notice to Petitioner along the same lines and advising of civil penalties for violation of pollution control laws. On May 3, 1975, Petitioner filed an incomplete application for the temporary operating permit. However, it was not until January 20, 1976, that Petitioner ostensibly furnished the necessary exhibits and public notice of its application. By letter of February 9, 1976, the acting district manager of the Respondent, which had succeeded the Department of Pollution Control, informed Petitioner that the Public Notice which had been published did not meet departmental requirements. (Testimony of Quaas, Respondent's Exhibits 5, 13) On June 1, 1976, the Respondent issued a Notice of Violation to Petitioner which stated that the Surfside Dump was being operated without a valid and current permit in an unsafe and unsanitary manner and thereby had violated various provisions of Chapter 403, Florida Statutes, and Chapter 17-7 Florida Administrative Code. The notice included a section entitled "Orders for Corrective Action" which provided that the Petitioner should reimburse the Respondent for expenses, cease to accept any solid material as of September 30, 1976, and implement a specified system of operation and render monthly reports on the same. It also required Petitioner to close the site no later than July 1, 1977, with a final cover of two feet of clean compacted fill with side slopes not to exceed 3:1 slope, and for the entire site to be seeded or planted with grass or other suitable cover vegetation. The orders also required the Petitioner to complete his operating permit application by sending Respondent a compliance schedule and proof of publication of a Public Notice. Subsequently, on January 16, 1977, the parties entered into a "Consent Agreement and Final Department Orders" after having conducted informal negotiations in the matter. The agreement provided that Petitioner waived any right to a hearing under Chapter 120, F.S., and that it would close the site or convert it to a sanitary landfill within the time established in Rule 17-7.07, F.A.C. It required Petitioner to submit plans for closing or converting the site within a certain time period and for implementation of an Operation plan to cover each day's waste and any existing exposed waste with six inches of clean compacted fill. It further required the Petitioner to submit a plan for monitoring ground water for leachate no later than January 30, 1977. Thereafter, on February 25, 1977, Nathaniel M. Zemel, a consulting engineer employed by Petitioner, submitted a "Landfill Closing Plan" to Respondent's West Palm Beach office which provided for a minimum of 24 inches of earth cover over all refuse on the site. Mr. Zemel estimated that between 250 thousand and 300 thousand cubic yards of fill material would be required to complete the covering operation. However, by letter of March 25, 1977, Petitioner advised Respondent that it did not concur in Mr. Zemel's plan and that Dr. Damodar S. Airan would "further refine the plan to reflect new information." The Airan report was submitted to Respondent on October 5, 1977, and essentially concluded that the existing vegetation on the site would be killed and that other harmful effects would result if a final cover of two feet of fill were to be placed over the landfill area. The report therefore recommended that exposed areas of the dump be covered with approximately six inches of clean fill and that corrective measures for surface drainage be accomplished, including sloping, grading, and possible catchment and retention of surface runoff by a drainage canal leading to a small retention basin on the site. A closing plan with drawings to accomplish the report's recommendations was filed with Respondent on November 1, 1977. (Petitioner's Exhibit 1, Respondent's Exhibits 6, 7, 14-17) Respondent's staff reviewed the Airan report and closing plan and was of the opinion that the study did not prove the basic premise that six inches of cover over the dump area was adequate. Thereafter, on December 4, 1977, Respondent issued a Final Consent Order for Dump Closing," Order No. 91, which ostensibly permitted the Petitioner time to undertake a soil and vegetation effectiveness study conditioned upon its agreement to implement and adhere to a final closing and cover plan as determined by the Department upon its review of the results of the study. This order obviously had been framed prior to the submission of the Airan report since that report was the "soil and vegetation effectiveness study" referred to in the consent order which was to be submitted not later than October 5, 1977. The order also provided that Respondent's determination of a final closing and cover plan would be made no later than December 1, 1977 and that the final closing would be accomplished no later than March 1, 1978. Again, the terms of the Consent Order provided that the Petitioner waived any right to a hearing or administrative or judicial review of its terms. Respondent's review and determination of Petitioner's aforesaid study was reflected in a letter to Petitioner from its subdistrict manager, Warren G. Strahm, dated January 3, 1978. It stated that Petitioner's study did not provide evidence that six inches of final cover would minimize and control potential water pollution from vertical percolation of surface water, but that Petitioner's own report showed that thirty-two million gallons more of percolation would result from a six inch as opposed to a two foot final cover. The letter therefore directed Petitioner to implement and adhere to a final closing and cover plan that included a final cover of no less than two feet of compacted earth, grading and sloping of the area, seeding or planting the site with grass or suitable cover vegetation, monitoring of ground water for leachate , and compliance with all other requirements of Rule 17-7.07, F.A.C., by March 1, 1978. Petitioner thereafter filed suit against Respondent in the First District Court of Appeal, Case No. 11-447. The suit was dismissed on May 19, 1978, by joint stipulation of the parties wherein it was agreed that Petitioner would seek a Section 120.57, F.S., hearing. On May 25, 1978, Petitioner filed such a petition with Respondent seeking to have that agency declare Petitioner's final cover and closing plan requiring six inches of final cover to be valid, and that final cover only be required on those portions of the Surfside Dump which were actually used on or after October 1, 1974. (Petitioner's Exhibit 2, Respondent's Exhibits 8, 18, 19) The Surfside Dump has been closed to the receipt of solid waste since March 1977. Although some clandestine dumping of waste has occurred since that time, it has mostly been confined to an area outside of the fenced portion of the site. There are presently relatively small areas of exposed waste in about fifty per cent of the landfill area. Some waste may be seen at the ground level in vegetated areas. A certain amount of ponding occurs in areas of both sparse and dense vegetation. There is a heavy vegetative growth over approximately 90 to 95 per cent of the dump site, consisting primarily of torpedo grass, para grass, guineagrass, common rag weed, caster bean, and sedge. Torpedo grass is a principal species and is abundant in about two thirds of the vegetated area. (Testimony of Quaas, Conn, Hudson, Stotts, Hussin, Gatewood, Busey, Airan, Petitioner's Exhibits 1, 4, 5, Respondent's Exhibits 10-12) Ground water or infiltrating surface water moving through solid waste can produce leachate, a solution containing dissolved and finely suspended solid matter and microbial waste products. Leachate may leave a landfill at the ground surface as a spring or percolate through the soil and rock that underlie and surround the waste. However, since the solid waste is of variable composition, it is not possible to accurately predict contaminant quantities. In completed fills, the amount of leachate can be expected to decrease with time. Leachate percolating through soils underlying and surrounding the solid waste is subject to purification of the contaminants in a variety of ways, but is diluted very little in ground water. Although leachate from a landfill can contaminate ground water, it is necessary to determine the quality of ground water and the aquifer's flow rate and direction to assess its results. Grading of the landfill is a means of diminishing surface infiltration by promoting surface water runoff. Vegetation of a landfill helps to stabilize cover material and thus reduce infiltration. It also reduces infiltration by intercepting and evapotranspiring some of the precipitation. The soil cover over a landfill also reduces percolation into the landfill depending upon its permeability. Clayey and silty loams are well suited for final cover, but are not readily available in South Florida. Sandy soils are primarily available in that area, but allow increased infiltration of precipitation. As a landfill ages, the earth cover will be subject to settlement and maintenance may be required to fill in depressions to avoid ponding of rain water. Such a program should provide for repairing cracks in the fill area due to uneven settlement and reseeding and fertilizing as necessary on the repaired areas, to prevent major erosion and surface water ponding. Leachate leaving the bottom of solid waste can be undesirable for drinking water, surface water, industrial water or irrigation water. However, it is most difficult to determine the character and amount of leachate from a particular area due to the many complex factors involved in such an assessment. The most common method for leachate control is to minimize the amount of water infiltrating the site. Ground water monitoring is accomplished by obtaining samples from wells placed at various locations on and near the landfill. It is generally agreed among the expert authorities that a minimum of two feet of compacted soil is required for the final cover when closing a landfill under normal circumstances. It has been the policy of Respondent to apply the sanitary landfill closing requirements of a two foot final cover, as specified in Rule 17- 7.05(3)(m), F.A.C., to the closing of dumps. (Testimony of Quaas, Conn, Hudson, Stotts, Hussin, Busey, Snider, Respondent's Exhibits 21-27) Expert testimony establishes that most of the vegetative cover on the Surfside Dump will be killed if a two foot cover is placed over it. The plants would re-colonize after such disturbance, but it takes almost two years for new plant growth to reach maturity. The present vegetation has been on the site for a number of years. Vegetation normally will grow at a better rate if its roots extend through the cover soil into the solid waste. However, certain gases created from waste material can be deleterious. A six inch final cover over vegetation would permit certain species to survive well, including torpedo grass, which is abundant on the site. In bare areas, it is best to sprig torpedo grass which provides relatively rapid growth, or to plant bahia grass. (Testimony of Hudson, Gatewood, Busey, Petitioner's Exhibit 1) The landfill site consists of an undulating terrain with surface drainage going in different directions from high to low level areas, but the overall drainage pattern is in a northerly direction. Two low-lying areas in the center and eastern portions of the landfill are subject to ponding after rainfall. These areas need to be filled, graded and planted in order to provide an overall northward direction of flow, together with grading and sloping on the eastern and southern boundaries of the area. Petitioner proposes to install subsurface drainage pipes, if found necessary, to promote horizontal movement of surface water and to provide catchment and retention of surface runoff diverted from the landfill area. This may include a shallow drainage canal along the northern boundary leading to a small retention basin in the northwest corner. Although these proposals were included in Petitioner's final closing plan submitted to Respondent, they were not considered by the latter's staff in evaluating requirements for the dump closing. Some profile corrections of the site were accomplished during the past year which eliminated ponding in the southwest corner of the landfill and improved drainage in the western portion. When further profile corrections are made to remove the remaining low spots, it is estimated that surface and subsurface runoff would increase and result in less leachate reaching the ground water table. (Testimony of Hudson, Airan, Petitioner's Exhibits 1, 4) Field and laboratory tests performed to determine the permeability of the soils on the landfill were performed by Petitioner at representative sites and by surface and subsurface soil samples. These tests showed that the infiltration rate at unvegetated locations was lower than that of adjacent vegetated areas, but this was attributed to the fact that in unvegetated areas, the soil is heavily compacted, very rocky, or no fill material is present. When infiltration was measured directly on waste material, it was found to be lower than that for surface soil. Mathematical calculations as a result of the tests showed that a maximum of 32 million gallons more would percolate annually through a six inch soil cover than a two foot cover. However, these calculations did not take into consideration the amount of surface and subsurface runoff. Petitioner's experts estimate that at least half of the percolation would be dissipated in that manner, leaving approximately 16 million gallons annually that would penetrate through the solid waste to the ground water. In considering this fact and the amount of water flowing laterally through the waste material, Petitioner concludes that only approximately one per cent of the total water flowing through the average ten foot waste layer under the water table would consist of vertical percolation. (Testimony of Airan, Petitioner's Exhibits 1, 4, 6-8, 10-13, Respondent's Exhibit 31-33) The Surfside Dump overlies the Biscayne aquifer. The Snake Creek Canal at the southern boundary of the dump site flows into Biscayne Bay some miles distant. There is a well field approximately one mile south of the dump at Carol City. Upstream of the Snake Creek Canal to the west is the North Dade County Landfill which is still in use. Snake Creek Canal is approximately fifteen feet wide and the bottom of the canal is approximately fifteen feet below original ground level. It is approximately thirty feet below the top of the landfill surface. Ground water flows generally in a southeasternly direction through the landfill. Approximately ten per cent of the ground water flows through the solid waste and the remaining 90 per cent bypasses and goes around the perimeter of the landfill. In May, 1977, a water quality monitoring program was undertaken by Petitioner that utilized nine sampling wells in three clusters of three each located in the northwest corner, center, and southeast corner of the landfill. In each cluster, one well was drilled to about five feet below the solid waste layer, the second ten feet below that point, and the third was ten feet above the waste layer. Water samples were taken in 1977 and in 1978. Tests of the samples showed that water quality generally improved with the depth of the well, and that the center group of wells had the highest level of contaminants because they were drilled in the middle of solid waste layers. In a number of instances, the pollutant levels for various substances were in excess of state standards. One well in the center of the landfill was dry during the rainy season which could indicate that the center of the landfill is less permeable than the outer layers and that a certain amount of water had been subject to subsurface runoff. It is conceded by both parties that the location and method of sampling wells does not provide sufficient definitive information concerning water quality in the area and that further monitoring needs to be undertaken in the future. Testing of Snake Creek Canal from points upstream and downstream of the Surfside Dump show that the surface water quality is most affected by contaminants from upstream. The North Dade County Landfill west of the Surfside Dump is undoubtedly a major influence on the quality of Snake Creek Canal water prior to reaching the Surfside Dump area. Leachate has not been found in canal water samples even though it is sufficiently deep to intercept the same if present. However, it is conceivable that any leachate plume could extend below the bottom of the canal. (Testimony of Stotts, Hussin, Snider, Airan, Patton, Petitioner's Exhibits 1, 4, 9, 12, Respondent's Exhibits 29 a-f) Based on the foregoing Findings of Fact, it is further found: The Surfside Dump presently is contributing to contamination of the ground water table in an unknown amount and is a potential source of pollution to the Snake Creek Canal and Biscayne Bay; The amount of pollution caused by leachate can be reduced through the implementation of corrective measures for surface drainage, including the filling of low lying areas, and grading and sloping to permit maximum surface water runoff. Additionally, infiltration of water into the landfill will be reduced by preserving the existing vegetation thereon which is an important factor in stabilizing surface cover and reducing percolation through evapotransportation most of the present vegetation will not survive if a two foot cover of soil is placed over it, and reestablishment of vegetation to its present state will take approximately two years. A surface cover of six inches over the vegetation would permit survival of most existing vegetation.
Recommendation That Respondent issue a final order requiring Petitioner to comply with the requirements set forth in paragraph 6 of the foregoing Conclusions of Law with regard to closing the Surfside Dump.

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

The Issue The issues presented in the case are whether Respondents P & L Salvage and Marlene Ballard are liable for violations of state statutes and rules, as alleged in the amended NOV, and, if so, whether the proposed corrective action is appropriate, and whether the proposed civil penalties and costs should be paid by Respondents.
Findings Of Fact The Parties The Department is the state agency charged with the power and duty to administer and enforce the provisions of Chapters 376 and 403, Florida Statutes, and the rules promulgated in Florida Administrative Code Title 62. Respondent P & L Salvage, Inc., is a Florida corporation. P & L Salvage owned and operated an automobile salvage yard at 4535 and 4537 West 45th Street in West Palm Beach, Florida (the “property,” “facility,” or “site”). The property comprises less than two acres. Respondent Marlene Ballard is a Florida resident and the president, treasurer, secretary, and director of P & L Salvage, Inc. Historical Use of the Site Beginning in the 1960s, the site was used as an auto salvage yard, first under the name Johnny’s Junkyard and later as General Truck Parts. In 1981, the owner of the salvage yard, Marie Arant, sold the facility. The record is not clear about the exact identity of the purchaser. The Alliance report, referred to later, states that the property was purchased by “the Ballard family.” The record evidence is insufficient to prove that Marlene Ballard ever owned the salvage yard. The parties agree that the salvage yard was operated for a time as P & L Salvage, which was unincorporated. Then, in January 1990, the site was purchased by Respondent P & L Salvage, Inc., which owned the site continuously until January 2007. Marlene Ballard lived in a house on the site from the 1980s until the property was sold in 2007. A separate building at the site was used as P & L Salvage’s office. The general operation of the salvage yard was to bring junk cars and trucks to the site, remove fluids from the vehicles, remove parts for sale, and then crush the dismantled vehicles in a hydraulic crusher to prepare them for transport and sale as scrap metal. The automotive fluids removed from the junked cars were stored on the site in 55-gallon drums for later disposal. Respondents presented evidence to show that the person who had the most knowledge of and managed the day-to-day operations in the salvage yard was an employee named John Boyd. When John Boyd ceased employment at the salvage yard, Marlene Ballard’s son, Thomas Ballard, took over the management of the yard. Respondents contend that no evidence was presented that Marlene Ballard conducted or participated in any activities that resulted in contamination, or that she had authority to prevent any potential contamination that might have occurred. However, Ms. Ballard was familiar with the activities in the yard, having worked and lived on the site for many years. She did the bookkeeping and signed payroll checks. All employees answered to Ms. Ballard. She contracted for environmental assessment and remediation work, and signed the hazardous waste manifests. She was acquainted with the contamination that could and did occur at the salvage yard. Eagle Sanitation, Inc., which operated a roll-off container business, leased the site from September 2005 until January 2007. Eagle Sanitation also obtained an option to purchase the property. At first, Eagle Sanitation only leased about a quarter of the site because there were many junk autos, tires, and other salvage debris still on the site in September 2005. For several months, Thomas Ballard continued to sell auto parts and scrap from the site, and to clear the site. Eagle Sanitation did not have complete use of the site until early in 2006. Eagle Sanitation’s business consisted of delivering roll-off containers for a fee to contractors and others for the disposal of construction debris and other solid waste, and then picking up the containers and arranging for disposal at the county landfill or, in some cases, recycling of the materials. Roll-off containers at the site were usually empty, but sometimes trucks with full containers would be parked at the site overnight or over the weekend. During its lease of the site, Eagle Sanitation did not collect used oil or gasoline and did not provide roll-off containers to automotive businesses. No claim was made that Eagle Sanitation caused any contamination found at the site. Contamination at the Site In 1989, Marlene Ballard contracted with Goldcoast Engineering & Testing Company (Goldcoast) to perform a “Phase II” environmental audit. Goldcoast collected and analyzed groundwater and soil samples and produced a report. Cadmium, chromium, and lead were found in the soil samples collected by Goldcoast. Some petroleum contamination was also detected in soils. These pollutants are all associated with automotive fluids. The Goldcoast report states that groundwater samples did not indicate the presence of pollutants in concentrations above any state standard. The Goldcoast report did not address the timing of discharges of contaminating substances that occurred at the site, except that such discharges had to have occurred before the report was issued in 1989. That is before the property was purchased by P & L Salvage, Inc. During an unannounced inspection of the salvage yard by two Department employees on August 15, 1997, oil and other automotive fluids were observed on the ground at the site in the “disassembly area” and around the crusher. There were also stains on the ground that appeared to have been made by automotive fluids. No samples of the fluids were taken or analyzed at the time of the inspection. The Department inspectors told Marlene Ballard to cease discharging fluids onto the ground, but no enforcement action was initiated by the Department. Ms. Ballard was also told that she should consider removing the soil where the discharged fluids and staining were observed. In early 1998, RS Environmental was hired to excavate and remove soils from the site. This evidence was presumably presented by Respondents to indicate that they remediated the contaminated soils observed by the Department inspectors, but no details were offered about the area excavated to make this clear. In 2004, in conjunction with a proposed sale of the site, another Phase II investigation of the site was done by Professional Services Industries, Inc. (PSI), and a report was issued by PSI in May 2004. The PSI report is hearsay and, as such, cannot support a finding of fact regarding the matters stated in the report. Presumably as a result of its knowledge of the PSI report, the Department issued a certified letter to Ms. Ballard on June 24, 2005, informing her that the Department was aware of methyl tert-butyl ethylene (MTBE) contamination at the facility. MTBE is an octane enhancer added to gasoline. The Department’s June 2005 letter advised Ms. Ballard that Florida Administrative Code Chapter 62-780 required “responsible parties” to file a site assessment report (SAR) within 270 days of becoming aware of such contamination. The letter also informed Ms. Ballard of the proximity of the City of Riviera Beach’s wellfield and the threat that represented to public drinking water. The June 2005 letter was returned to the Department unsigned. In October 2005, the Department arranged to have the letter to Marlene Ballard served by the Palm Beach County Sheriff’s Office. The Department received a confirmation of service document that shows the letter was served by a deputy on October 14, 2005, but this document is hearsay and does not support a finding that Ms. Ballard had knowledge of the contents of the letter. The Department did not receive an SAR within 270 days, but no enforcement action was immediately initiated. On December 15, 2006, the Department issued a six- count NOV to P & L. Salvage, Inc. P & L Salvage requested a hearing and the matter was referred to DOAH. In January 2007, in conjunction with Eagle Sanitation’s proposed sale of its purchase option to Prime Realty Capital, LLC, Alliance Consulting & Environmental Services, Inc., (Alliance) conducted a site assessment at the site and produced an SAR in April 2007. At that time, as indicated above, P & L Salvage had ceased operations at the site and Eagle Sanitation was operating its roll-off container business there. The SAR states that in January 2007, “[a]pproximately 80 yards of black stained oily-solidified shallow sands were excavated [by Eagle Sanitation] from the central and northeastern portions of the site, where car crushing, fluid draining and battery removal were historically conducted.” The soil contained lead, iron, chromium, cadmium, and arsenic, but testing did not show the excavated soils constituted hazardous materials and, therefore, the soils were disposed at the county landfill. The area of soils where the Department inspectors in 1997 observed automotive fluids and staining appears to have been included in the soils that were excavated and removed in 2007. The Department presented no evidence to the contrary. Testing by Alliance of other soils at the site showed “no significant petroleum metals concentrations” and Alliance did not recommend the removal of other soils. The presence of an MTBE “plume” of approximately 30,000 square feet (horizontal dimension) was also described in the SAR. The plume is in the area where the crusher was located. Several groundwater samples from the site showed MTBE in concentrations above the target cleanup limit. The City of Riviera Beach operates a public water supply wellfield near the site. The closest water well is approximately 250 feet from the site. The SAR concludes that “the potential exists for the MTBE plume to be pulled downward” toward the well, and recommends that a risk assessment be performed. Alliance recommended in the SAR that the MTBE contamination be remediated with “in-situ bioremediation” with oxygen enhancement. No remediation has occurred on the site since the date of the Alliance report. The Alliance report did not address the timing of contaminating discharges that occurred at the site. To the extent that Alliance reported contamination in 2007 that was not reported in the 1989 Goldcoast report, that is not sufficient, standing alone, to meet the Department’s burden of proof to show that P & L Salvage, Inc., caused “new” contamination after 1989. Competent evidence was not presented that the Alliance report describes “new” contamination. The authors of the reports were not called as witnesses. No expert testimony was presented on whether the data in the reports can establish the timing of contaminating discharges. It is not the role of the Administrative Law Judge, nor does he have the requisite expertise, to compare the environmental assessments conducted by Goldcoast and Alliance and make judgments about whether some of the contamination reported by Alliance had to have occurred after 1989. Although the Department’s expert, Paul Wierzbicki, testified that it was his opinion that the contamination was attributable to the “operations of the P & L Salvage yard facility,” he was answering a question about “what caused the contamination” and, in context, his testimony only confirmed that the type of contamination shown in the photographs and reported in the site assessment reports was the type of contamination associated with auto salvage yards. Mr. Wiezbicki’s testimony is not evidence which can support a finding that the contamination at the site, other than the automotive fluids and stained soils observed by the Department inspectors in 1997, was caused by P & L Salvage, Inc.1 On June 12, 2007, after reviewing the Site Assessment Report, the Department issued a letter to Marlene Ballard, requesting additional data and analysis. At the hearing, the Department presented a responding letter from Alliance dated June 21, 2007. It was disputed whether the Alliance letter is evidence of Ms. Ballard’s receipt and knowledge of the Department’s June 12, letter. However, even if Ms. Ballard did not know about the Department’s letter in June 2007, she certainly became aware of the letter in the course of this proceeding. The amended NOV issued in January 2008 mentions the letter, and the letter was listed as an exhibit in the parties’ June 4, 2008 Pre-hearing Stipulation. On January 24, 2008, the Department issued an amended NOV which dropped three counts from the original NOV and added two new counts. Most significantly, the amended NOV added Marlene Ballard and Thomas Ballard as Respondents. P & L Salvage and Marlene Ballard responded to the amended NOV with petitions for hearing. Thomas Ballard did not respond. At the hearing, the Department presented testimony of employees that were involved in this enforcement action regarding the value of their time expended on various tasks associated with this case. Bridget Armstrong spent eight hours inspecting the site of the contamination, eight hours drafting the NOV and consent order, approximately 30 hours reviewing technical documents, and 15 hours corresponding with Respondents. Ms. Armstrong’s salary at the time was about $20.00 per hour. Paul Wierzbicki spent 16 hours investigating facilities in the area, reviewing the contamination assessment reports, and overseeing the enforcement activity of his subordinates. Mr. Wierzbicki was paid $33.00 per hour. Kathleen Winston spent 10 hours reviewing a site assessment report and drafting correspondence. Ms. Winston’s salary at the time was $23.56 per hour. Geetha Selvendren spent 4-to-5 hours reviewing the site assessment report. She was paid $19.00 per hour at the time. Finally, Joseph Lurix spent three hours reviewing documents. His salary at the time was $34.97 per hour.
Findings Of Fact The property upon which Petitioner seeks a variance from the normal requirements for attaining a permit to install an on-site sewage disposal system is found in Leon County, Florida. Specifically, it is located at Lot 4, Block A, Killearn Lakes Unit I. The relative position of this lot in the subdivision is depicted within Petitioner's Exhibit 1 and Respondent's Exhibit 2 admitted into evidence. Respondent's Exhibits 3 through 5 are photographs of the site. Petitioner intends to construct a 1,200 square foot residence. As the photographs depict, some preparation has commenced to the extent of lot clearing and other site work where the home would be constructed. Killearn Lakes Unit I is a pre-1972 subdivision. When the development commenced, it was anticipated that a community sewer system would be utilized, as contemplated by the plans submitted in April, 1971. Subsequently, some lots within the Killearn Lakes Unit I were allowed to be developed with the use of on-site sewage disposal systems, namely septic tanks. There are 150 lots in that category. In 1979, with the advent of certain rules under Chapter 10D-6, Florida Administrative Code, the development was allowed to proceed on the basis of four septic tanks per acre. Over time, Killearn Lakes Unit I experienced a history of failures with on-site sewage disposal systems. The failures were promoted by problems with the "sheet flow" drainage system and its patterns of dispersion of storm water runoff, problems of soil permeability and abnormally high wet season water tables, referred to as perched water tables. This resulted in sewage backing up into homes and flowing out onto the ground in the yards of the residences, into streets and onto adjacent neighbors' lots. The problems experienced were widespread within the Killearn Lakes Unit I. This seepage of raw sewage presented a health hazard, as it would on any occasion. Among the residences confronted with this dilemma was Lot 5, Block X, adjacent to the subject lot. Persons residing in that home had to undertake alternative means of on-site sewage disposal to have that system function properly. This included relocation of the apparatus, mounding, use of an aerobic system, and use of pumps to insure that the waste being disposed did not back up into the conveniences within the home. Witnesses who appeared at the hearing described the series of corrections in some detail. Those witnesses included a former owner of that residence and others who had a technical understanding of the problems in that system. The problems in Killearn Lakes Unit I related to on-site sewage disposal systems became so extreme that the Leon County Commission declared a moratorium on the installation of on-site septic tanks in that development. This occurred in 1987. In order to better understand the problems in the Killearn Lakes subdivision, to include Killearn Lakes Unit I, a study was commissioned. That report is referred to as Killearn Lake Waste Water Disposal Study of June, 1987. A copy of the report is found as Respondent's Exhibit 6 admitted into evidence. It was prepared for the Leon County Board of County Commissioners and prepared by the Leon County Public Health Unit with the assistance of the Leon County Department of Public Works, Leon County Building Department, Ochlockonee River Soil and Water Conservation District, Northwest Florida Water Management District, Tallahassee-Leon County Planning Department, Florida Department of Health and Rehabilitative Services, and Florida Department of Environmental Regulation. Some of the highlights of that report concerned the observation that the septic tank systems do not work adequately and that the more systems that are placed the greater the problems. It noted that the nature of the drainage system in this area is a contributing factor to the failures. The soil's poor permeability, relating to the Dothan series of soils in the area which have slow permeability, contributed to the problem. Perched water tables were found above the expected levels for the wet season water tables. They also presented a problem, as did excessive slopes in some areas. In particular, it was noted that 80% of the lots sampled in Killearn Lakes Unit I had severe limitations on the use of on-site sewage disposal systems. Ninety-three per cent of the lots sampled in Block X received excess runoff from other lots and roads at higher elevations. It was noted that French or curtain drains alone would not significantly reduce perched water table complications because of the low permeability of the soils. It was reported that the overall housing density of Killearn Lakes is not particularly high, but the individual lots are small, approximately 1/4 acre in size. This, taken together with the fact that the "sheet flow" concept of storm water management contemplates that the runoff will cascade across the terrain conforming to its contours, means that some small lots will be inundated. This uncontrolled runoff contributes to septic tank problems in that the tanks fail when the soils around them become saturated. The report notes that if there was a different designed drainage system, the impact on septic tanks would be less. The report notes that if something is not done to modify storm water runoff, drainage problems will persist. Consequently, septic tank failures will continue to occur. Concerning the water tables, the soil testing, which was done in Killearn Lakes Unit I, in which the predominant soil is Dothan type, demonstrated that the borings which located mottling of the soils at the expected level of the wet season water table were inaccurate. These indicators did not correspond to reality in that the true water tables were found 12-20 inches above the expected level of the average high water, as seen in the mottling. This phenomenon was revealed in 42% of the lots evaluated which had Dothan soils. The report recommended, among other measures, that no new sewage disposal system permits be issued in Killearn Lakes Unit I until a storm water system had been constructed and demonstration made that the system would collect storm water and thereby lower the perched water table on specific lots under review. The ultimate response to the question of permits for on-site sewage disposal systems in Killearn Lakes Unit I was spoken to in a Resolution of July 14, 1987 entered by the Leon County Board of County Commissioners. A copy of the resolution may be found as Respondent's Exhibit 1 admitted into evidence. It was resolved that the permits for on-site septic disposal systems be reviewed by the Leon County Public Health Unit on a case-by-case basis in accordance with criteria announced at Chapter 10D-6, Florida Administrative Code. This effectively lifted the moratorium. The subject request for installation of an on-site sewage disposal system was reviewed in keeping with the policy decision set forth in the resolution. Respondent's Exhibit 6 admitted into evidence includes a copy of a survey made by the Homeowners' Association for Killearn Lakes, also admitted as Petitioner's Exhibit 1. As part of the study commissioned by the Leon County Board of County Commissioners, it has some relevance in portraying the dimensions of the problem. Those dimensions are better understood by resort to the color scheme which is found in Petitioner's Exhibit 1. It depicts the problem lots in red color, those lots without problems in green color, and the lots upon which no report was made in orange color, as well as vacant lots, to include the subject lot, which have no color scheme. This latter category indicates no participation in the survey. The door-to-door personal survey conducted by Rod Moeller and testified about at hearing does not diminish the impression of the seriousness of the problem with on-site sewage disposal system failures in Killearn Lakes Unit I, which the 1987 study by the Leon County Board of County Commissioners identified. This survey by Mr. Moeller was in a limited area, more specifically related to the portion of Killearn Lakes Unit I nearby the subject lot. The findings of the 1987 study commissioned by the Leon County Board of County Commissioners are accepted as accurate. Eanix Poole, Administrator of Environmental Health for the State Health Office testified at the hearing. He pointed out that the failure rate in the subdivision under question for on-site sewage disposal systems is 25%, as contrasted with the statewide rate of less than 1/2%. He identified the fact that those failures relate to backups within the home and seepage onto the ground. He verified that these events constitute health problems, especially given the number of failures. He sees the lot in question here as being particularly vulnerable to problems given the drainage patterns and its location at the bottom of two hills. The lot in question receives runoff from the two adjacent lots as well. Mr. Poole sees the subject lot as more vulnerable in the wet season and does not believe that any alternatives that are available for placement of the system on the site would sufficiently alleviate the potential failure of the system to make it a successful arrangement. What he sees is a lot in the path of a natural drainage of tremendous quantities of storm water runoff, coupled with poor soil conditions related to soil absorption or permeability in an area where on-site sewage disposal systems have failed. He remarks that dry soils are needed to treat the sewage and that treatment cannot take place in a saturated soil environment. The effects of seepage of the sewage, according to Mr. Poole, is one which can degrade ground water. Mr. Poole is also concerned that the installation of the proposed on-site sewage disposal system above ground will have an adverse impact on the adjacent lots, one of which has already experienced problems. That refers to Lot 5, Block X. These observations by Mr. Poole, as reported, are accepted. Raymond Collins, an environmental administrator with the Respondent's health program office, also testified at the hearing. He is intimately aware of the problems in Killearn Lakes Unit I. Those problems began to occur in the winter of 1986 and continued into 1987. This related to problems with toilets and the seepage of effluent which was running onto people's property and into the streets. He notes a similar failure rate in Killearn Lakes Unit I to that observed by Mr. Peel when contrasted with the experience statewide. In the aforementioned period he received calls and reports from homeowners concerning system failures. In effect what was happening was that the on-site drain fields in Killearn Lakes Unit I would not accept more input and the raw sewage would bubble up and leach out onto the ground. He personally observed a dozen sites which had failures. He was responsible for the coordination of the July, 1987 study which has been mentioned. As a result of that study one of the steps which he took was to advise that staff investigating the permit application requests should elevate the estimation of the wet season water table by 12-20 inches. Mr. Collins agrees with the recommendation of the individual who was assigned to evaluate the application for permission to install an on-site sewage disposal system at the subject lot, who recommended that the application be turned down. Mr. Collins' description of the experience at Lot 5, Block X, related to his knowledge that the initial system had been replaced with an aerobic system, which also proved to be an inadequate on-site sewage disposal system. In 1988, he went to the home of the person living on that lot, and the aerobic system was not working. There was a light rain on that day, and there were problems in the drain-field area. When a soil boring was made to a depth of two feet effluent poured out. The perched water table had risen to a point in the bottom of the drain field, such that when a hole was punched, it provided a conduit for pressure to be relieved. The drain field that was experiencing this problem was not the original drain field. It was a replacement drain field. The drain field being observed was in the front of the lot, right below the ground. The suggestion to alleviate the problem was to move the drain field to the side of the yard and elevate it and install a series of small-diameter pipes. A pump was also needed to move effluent into the drain field, thus, avoiding a backup of the system into the home. He is unaware of any recent failures in the system at Lot 5, Block X. Mr. Collins emphasized the need for soil to remain unsaturated to provide effective treatment and that 24 inches of unsaturated soil is the minimum amount which would be acceptable. Mr. Collins commented about the nature of the subject lot and the fact that other lots drain through it. Mr. Collins commented that the design of the proposed septic tank does not assure success in the treatment of the waste disposed. Unlike the expert of the Petitioner, Mr. Peel, the problem is not that solids are blocking up the system. It is the failure of the soils to accept the volume of water which is being released from the chambers of the septic tank into the drain field. Mr. Collins does not believe that the use of water-saving appliances in addition to the limited size of the home to be built on the subject lot, installation of an aerobic system, and installation of an above-ground system, as proposed, would be successful and not pose a health risk from system failure. The problems would continue to be drainage patterns and poor soils. His remarks, as reported, are accepted as accurate. Terese A. Hegg, Environmental Specialist I with the Respondent's Leon County Public Health Unit, reviewed the application for variance to install the on-site sewage disposal system. She was familiar with the history of problems in Killearn Lakes Unit I before undertaking this assignment and has made more than 50 evaluations in that development. She observed that the "sheet flow" drainage of storm water does not provide reasonable management because it does not drain normally. She is aware that the wet season water table is as much as 20 inches above the normal indicators, as seen through mottling. Her analysis of this site is under the auspices of those requirements announced in Chapter 10D-6.044, Florida Administrative Code, having in mind that the subdivision plat was made before 1972. This includes an examination of the soil characteristics, history of flooding, and water table evaluations. At this site, she noted the poor permeability of the soil. She did soil borings to confirm the nature of the soils and to identify the water table. She took into account the abnormal perched water table that is above what the mottling would indicate as being the wet season water table. Ms. Hegg is concerned that the system on the adjacent lot, which is now functioning adequately, would not function adequately if the subject system was installed. She noted that the drainage pattern from the neighboring lots was toward the subject lot and that water would come from the left and the right lots adjacent to this lot, corresponding to Lots 5 and 3 as you face them. The drainage pattern would then proceed beyond Lot 4 and into a green area. In making her assessment of this application, she was aware of the problems with the on-site sewage disposal system at Lot 5, Block X. The appearance of saturated soil in the entire length of the boring and standing water on the lot is an indication of problems with percolation. The effluent will flow out and onto the ground if these soils are saturated. From her observations and based upon the history of Killearn Lakes Unit I and its failures regarding on-site sewage disposal systems, Ms. Hegg does not believe that the proposed system would successfully address sewage treatment and would promote a risk of on-site sewage disposal system failures for adjacent lots. Ms. Hegg acknowledged that the storm water flows could be diverted; however, she points out that the subsurface water cannot be diverted. Her account of this site and the acceptability of the request for variance as reported is accepted as accurate. Given the soil conditions and the wet season water table expected at this site, the proposed system will not present an adequate unsaturated soil depth for treatment of the sewage and untreated sewage may be expected to seep or leach out onto the ground. On May 22, 1990, Mr. Collins had written to Dr. Richard G. Hunter, Assistant Health Officer for Environmental Health, recommending the denial of the variance request. A copy of that correspondence may be found as Respondent's Exhibit 7 admitted into evidence. It details reasons which are similar to those described in this Recommended Order. As a consequence, even though the Advisory Review Variance Board had looked with favor upon the request for variance, that variance was denied by action of Dr. Hunter on May 30, 1990, which relied upon the insights of Mr. Collins, as described in his May 22, 1990 correspondence. A copy of the letter of denial may be found as Respondent's Exhibit 8 admitted into evidence. The purpose of this hearing was not to examine whether Respondent had abused its discretion in denying the variance. The reason for the hearing was to allow the parties to present their points in an adversarial setting, which allowed each party to explain its viewpoint anew. That was done, and the analysis provided by this recommended order ensued. In deciding the facts, these representations have been made with due regard to the remarks of James Earl Peel, an expert in the design of on-site sewage disposal systems, who had on his staff, Gary L. Wood, P.E. His methods in analyzing the issue of the suitability of the installation of an on-site sewage disposal system at the subject site do not coincide with the methods contemplated in Chapter 10D-6, Florida Administrative Code, which controls. This is especially significant in his approaches to soil characteristics and location of the wet season water table. As noted above, his belief that the problem is one of distribution of solids from the septic tank into the drain field overlooks the more significant problem of water volume discharge from the septic tank into the drain field. In fact, Mr. Peel indicated that he is unfamiliar with the requirements of septic tank design, as described in Chapter 10D-6, Florida Administrative Code. On balance, Mr. Peel's reports, in Petitioner's Exhibits 3 and 4 admitted into evidence and his in-hearing testimony, do not persuade that the system he recommends can be successfully operated at the subject site. His presentation and the overall presentation of Petitioner do not create a reasonable expectation that the system will not fail and create health hazards for the residents of Lot 4, Block X, and others in the vicinity. It is recognized that this lot owner faces a hardship that was not caused by Petitioner. It is also recognized that, pursuant to the stipulation of the parties, there is no intention by any entity to install a community system of sewage disposal. It is further recognized that there are no alternative methods that would seem to be successful in addressing the problem of the treatment of the sewage, as related in the previous findings. On the other hand, the discharge that could be expected from this subject system would bring about a condition in which the effluent presented a health risk to this applicant and other members of the public and has the potential to significantly degrade the ground or surface waters, although this latter circumstance has not been documented on other occasions and was not found to exist in the July, 1987 study commissioned by the Leon County Board of County Commissioners. In that report, it was specifically found that the surface water had not been compromised by the on-site sewage disposal system failures described in the overall report.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that a Final Order be entered denying Petitioner's request for variance from permit requirements and permission to install an on-site sewage disposal system at Lot 4, Block X, Killearn Lakes Unit I. DONE AND ENTERED this 20th day of November, 1990, in Tallahassee, Leon County, Florida. CHARLES C. ADAMS, Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 20th day of November, 1990. APPENDIX TO RECOMMENDED ORDER IN CASE NO. 90-4456 The following discussion is given concerning the proposed facts of the parties: In the discussion of the testimony of Mr. Poole, the relevant portions of that testimony are reflected in the facts found in this recommended order. Under the heading of testimony said to be attributable to Ms. Hegg, at paragraph 1, while it is recognized that a system might be installed that might not call for diversion of storm water onto adjacent neighbors' properties, the problem on site would remain and would be sufficient reason to reject the application. Moreover, it is not clear that it is the intention to install a system that would divert storm water from adjacent properties. Paragraph 2 under this heading is rejected in its notion that storm water would not have an influence on the proposed system. Paragraph 3 is rejected. Paragraphs 4 and 5 do not lead to the conclusion that sufficient unsaturated soils would be available for the treatment of disposed sewage during the wet season, nor does the representation at paragraph 6. Paragraph 7 under that heading is contrary to facts found. The paragraphs under the reference to James Earl Peel, in those five paragraphs, while accurately portraying the opinion of Mr. Peel and Mr. Wood, does not lead to the conclusion that the application should be granted. Under the heading "Rod Moeller" in the first paragraph, the information provided at hearing and under weather reports does not satisfactorily establish what the rainfall circumstance may have been at the subject property 72 hours before January 24, 1990, as referred to in paragraph 1, nor can it be said that the rain experienced in the overall area contemplated by the attached weather report to the argument by Petitioner was a 25-year storm event. The comment at paragraph 3 under this category that the on-site sewage disposal systems in neighboring lots are functioning fine since modifications in the advent of hurricane "Kate" is contrary to facts found. Under the heading "Ray Collins" in paragraph 1, this proposed fact has no relevance in that the question is the appropriate function within Killearn Lakes Unit I, not at an undisclosed site away from that area. Respondent's Facts These facts are subordinate to facts found.
