The Issue The issue to be determined in this case is whether the Notice of Intent to Issue Order Requiring Access to Property (“Access Order”) issued by the Department of Environmental Protection (“Department”) and directed to Glenda Mahaney, as the property owner, is a valid exercise of the Department’s authority.
Findings Of Fact Petitioner Glenda Mahaney is a natural person and the owner of the property identified in the Access Order. The Department is the state agency which has been granted powers and assigned duties under chapters 376 and 403, Florida Statutes, for the protection and restoration of air and water quality and to adopt rules and issue orders in furtherance of these powers and duties. Background The groundwater beneath a parcel of land adjacent to Petitioner’s property was contaminated with petroleum when the land was used in the past for auto salvage operations. Initial groundwater sampling near the border of Petitioner’s property showed groundwater contamination by gasoline constituents which exceeded Groundwater Cleanup Target Levels (“GCTLs”). In other words, the contamination was at levels that required cleanup. However, later sampling showed the concentration of contaminants had decreased below GCTLs, probably as a result of natural attenuation. The existing data suggests that any groundwater contamination beneath Petitioner’s property is probably now at a level that would not require cleanup. However, the Department issued the Access Order because the Department is not certain about the contamination beneath Petitioner’s property and because Petitioner has continually requested further investigation. Petitioner believes contamination from the auto salvage site has caused illness in a tenant and even contributed to other persons’ deaths. However, no expert testimony was received on this subject and no finding is made about whether contamination exists on Petitioner’s property which has caused illness or death. The Department’s Site Investigation Section wants access to Petitioner’s property in order to determine whether contamination has migrated beneath Petitioner’s property and, if it has, the extent and concentration of the contaminants. The Department wants to: (a) install up to five temporary groundwater monitoring wells, (b) collect groundwater samples from the wells, (c) collect a groundwater sample from Petitioner’s potable water well, and (d) remove the monitoring wells after the sampling. The Access Order includes terms related to advance notice, scheduling, and related matters. Liability Although Petitioner believes petroleum contamination is present and wants it cleaned up, she objects to the provision of the Access Order related to liability. Paragraph 9(e) of the Access Order provides: Ms. Mahaney shall not be liable for any injury, damage or loss on the property suffered by the Department, its agents, or employees which is not caused by the [sic] negligence or intentional acts. Petitioner insists that she should not be liable under any circumstances for injuries or damages suffered by Department’s agents or employees who come on her property for these purposes. She demands that the Department come onto her property “at their own risk.” At the final hearing, the Department stated that it did not intend to impose on Petitioner a level of liability different than the liability that would already be applicable under Florida law. The Department offered to amend Paragraph 9(e) of the Access Order to indicate that Petitioner’s “liability, if any, shall be determined in accordance with Florida law.” Scope of the Investigation Petitioner objects to the proposed groundwater sampling because she does not believe it is extensive enough. Petitioner also believes the Department should test for soil contamination. The Department’s expert, David Phillips, testified that the proposed monitoring well locations were selected based on the direction of groundwater flow in the area and the wells are along the likely path of migration of any contaminated groundwater from the former auto salvage site. Another Department witness, Tracy Jewsbury, testified that no soil contamination was found on the auto salvage site, so the Department has no reason to expect there would be soil contamination on Petitioner’s property that came from the auto salvage operation. The Department will use the data collected from the wells to determine if contamination is present and whether future contamination assessment and/or remediation activities are necessary.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Environmental Protection withdraw the Access Order or, alternatively, that Paragraph 9(e) of the Access Order be amended to provide that Ms. Mahaney’s potential liability, if any, shall be determined in accordance with Florida law.

Findings Of Fact Kyle Brothers Land Company, Inc. filed its application with the Department of Environmental Regulation to excavate four canals and to unplug two canals which they had already dug within its development in Port Pine Heights located on Big Pine Key, Monroe County, Florida. The application of Kyle Brothers Land Company, Inc. was introduced as Composite Exhibit No. 1 and a plat of the proposed development was introduced as Exhibit 9. The proposed activity would be constructed on Class 3 waters as defined in Chapter 17-3, F.A.C. Test data submitted shows that the water quality of the water in the existing canals meets or exceeds the standards established in Section 17-3.09, F.A.C. The proposed canals, as well as the existing canals, are being developed as residential home sites. Two potential threats exist to the maintenance of water quality standards within the canals. The first threat is the short-term effect of increased turbidity of the waters due to the construction of the proposed activity. The second threat is the long-term effect of the increased pollution of the waters resulting from waste disposal through proposed septic tank systems to be used in the residential home sites adjoining the proposed and existing canals. The permit application appraisal, Exhibit 2, indicates that the short- term effects of increased turbidity could be controlled by the use of plugs, screens, and daily testing for turbidity and dissolved oxygen. The evidence further shows a variance in the depth of the existing canals and the two plugged canals. The two plugged canals and several of the existing canals have a depth greater than the central canal. The variance in depth permits the accumulation of debris and silt in the finger canals which under certain conditions could be stirred up and become suspended in the waters of the canals increasing the turbidity of the canals and violating the water quality standards. To prevent this from occurring these canals would have to be filled to bring them to the depth of the central canal. The long-term threat to water quality in the canals is the introduction into the canals of nutrients and chemicals attributable to surface water runoff and the proposed septic tank systems to be utilized on the residential home sites. Control of surface water runoff can be obtained by backs loping the uplands away from the canals. The control of nutrient loading associated with the septic tank systems is more complex. The Declaration of Restrictions for Port Pine Heights, Exhibit 7, recites that sewage disposal shall be by septic tank or central disposal plant. However, the plans submitted by the Applicant do not indicate any provision for establishment of a central disposal plant. Further, under the provisions of the deed restrictions there is no requirement that a resident of Port Pine Heights use a central disposal plant even if such a system were available. The current residents of Port Pine Heights currently use septic tank waste disposal systems; however, the number of current residents is substantially less than the number of residents that Port Pine Heights is designed to accommodate. The disposal of sewage by septic tanks will result in the introduction in the canal waters of partially treated effluent through exchange with subsurface waters in the porous limestone substrata present in the area. To maintain the water quality at the required level, the waste effluent from the residential development must be prevented from entering into the canal. Because of the substantial difference in the level of development existing in Port Pine Heights currently and the potential level of development, the test data and the projections based upon that data do not give reasonable assurances that the increased pollutions attributable to the use of septic tanks would not violate water-quality standards.
Recommendation Until the Applicant makes a reasonable, affirmative showing that the long- term effect of the activity will not violate the water-quality standards, the application should be denied. DONE and ORDERED this 22nd day of October, 1976 in Tallahassee, Florida. STEPHEN F. DEAN, Hearing Officer Division of Administrative Hearings Room 530, Carlton Building Tallahassee, Florida 32304 (904) 488-9675 ================================================================= AGENCY FINAL ORDER ================================================================= STATE OF FLORIDA DEPARTMENT OF ENVIRONMENTAL REGULATION KYLE BROTHERS LAND COMPANY, INC. Petitioner, vs. CASE NO. 76-607 DEPARTMENT OF ENVIRONMENTAL REGULATION, Respondent. /
The Issue Whether the Florida Department of Environmental Regulation's (DER's) inclusion in Rule 17701.050(5)(d)1, Florida Administrative Code, of the sentence, "The bottom of the liner shall be constructed above the 10-year seasonal high groundwater level" (the challenged sentence), constitutes an invalid exercise of delegated legislative authority and whether the economic impact statement accompanying this rule is inadequate.
Findings Of Fact All parties stipulated and agreed to Finding of Fact No. 1 in their Prehearing Stipulation and it is adopted herein. WMIF and DER stipulated and agreed to other operative facts in their Prehearing Stipulation and those stipulated facts are adopted herein. All stipulations were included in the Prehearing Stipulation of the parties. BFI is engaged in Florida and elsewhere in the business of solid waste collection and disposal. BFI owns and operates solid waste management facilities throughout the state. BFI has obtained, and will seek to renew, permits authorizing the construction and operation of these facilities. BFI also is in the process of seeking permits that would authorize construction of new solid waste management and disposal facilities in Florida. The proposed rule, if adopted, will apply to BFI and its applications for these various permits. Accordingly, BFI will be substantially affected by the adoption of the proposed rule. WMIF is a Florida corporation engaged in the business of solid waste collection, disposal, treatment, and management in the state of Florida. The proposed rule will have a substantial effect on owners and operators of solid waste management facilities, like WMIF. WMIF currently owns and operates several solid waste management facilities in this state and plans to construct and operate new facilities in the future. WMIF has investigated the possibility and feasibility of designing a landfill in Florida which calls for placement of a bottom liner below the groundwater level. WMIF would propose to utilize this option in designing some of its future facilities in Florida, if this option is available. The challenged portion of the rule would prohibit use of this option. DER's proposed revision of Rule 17-701.050(5)(d)1, Florida Administrative Code, substantially affects the interests of WMIF. DER followed the procedures in Chapter 17-102, Florida Administrative Code, in adopting its revisions to Chapter 17-701, Florida Administrative Code. In late 1989, DER developed draft revisions to Chapter 17-701, Florida Administrative Code, primarily addressing liner requirements for landfills subject to the rule. On January 31, 1990, DER held a public workshop on its draft revisions to Chapter 17-701, Florida Administrative Code. At that workshop DER distributed to the public its workshop draft of its proposed revisions (hereinafter "the January draft"). On page 34 of the January draft, DER proposed new rule provisions at Rule 17-701.050(4)(d)1, Florida Administrative Code, (subsequently renumbered), including the following language: The bottom of the composite or double liner shall be above the most recent ten-year historic seasonal high ground water level, unless the applicant can demonstrate that the landfill design will provide equivalent protection for the environment from the infiltration of leachate even when the bottom of the liner is in contact with groundwater. On February 6, 1990, WMIF submitted written comments to DER on the proposed rule revisions. In its written comments, WMIF suggested that the language of the January draft quoted above be stricken because "there are circumstances where the desirable landfill design could result in the base of the bottom liner being installed below an existing water table." On March 9, 1990, DER published a Notice of Rulemaking (hereinafter "hearing draft") presenting its proposed revisions to Chapter 17-701, Florida Administrative Code, in the Florida Administrative Weekly, Vol. 16, No. 10, in preparation for an adoption hearing before the Environmental Regulation Commission (ERC). The hearing draft contained numerous revisions from the January draft. The above-quoted language from the January draft was deleted in the hearing draft. In response to DER's publication of the hearing draft, WMIF filed the instant rule challenge contesting, among other things, Rule 17-701.050, Florida Administrative Code, and the adequacy of the Economic Impact Statement. The ERC held a public meeting on April 12, 1990, at which time it considered the rule revisions recommended by DER. At that meeting, DER distributed to those in attendance a Notice of Change which set forth changes DER then recommended to its published hearing draft. During the course of the ERC meeting, the challenged rule provision was drafted by DER in response to a request by ERC members, and the provision subsequently was adopted by the ERC. The amendment to Rule 17-701.050(5)(d)1, Florida Administrative Code, which was adopted by the ERC is as follows: The bottom of the liner shall be constructed above the 10-year seasonal high groundwater level. The challenged sentence was not included in the published hearing draft of the rule or in DER's April 12, 1990, Notice of Change. During the course of the ERC meeting on April 12, 1990, the ERC adopted Chapter 17-701, Florida Administrative Code, including the challenged sentence. Subsequent to the ERC hearing on April 12, 1990, DER prepared a second Notice of Change, incorporating the challenged sentence. Landfills are large, concentrated piles of chemical-containing materials of widely varied description. When precipitation occurs, moisture percolates down through the waste, dissolving chemicals in the waste and forming leachate. The goal of DER's landfill liner design criteria is to contain that leachate, to prevent it from contacting groundwater, and, while it is contained, to remove it and treat it. Leachate is contained by a properly designed and constructed liner and it is removed by a leachate collection and removal system. Landfill liners are imperfect and therefore they leak. Engineering principles are employed to design liner systems to compensate for the fact that liners leak. A properly engineered system will maximize groundwater protection. There are at least four factors which affect leakage through liner systems: hydraulic head, interface conditions, residence time, and gradient direction. With regard to hydraulic head, the operative principle is that the greater the pressure (the greater the hydraulic head on the liner), the greater the leakage rate through the liner. With regard to interface conditions, the operative principle is that the lower the permeability of the material underlying the liner, the less leakage will occur through the liner. With regard to residence time, the operative principle is that the faster the flow rate through the leachate collection system, the shorter will be the period of time that the leachate is in contact with the liner and therefore the lesser will be the amount of leakage through the liner system. With regard to the concept of gradient direction, there are two types of gradient: outward g and inward gradient. In utilizing an outward gradient design concept, the landfill liner system is constructed above the groundwater table. If a leak develops through the liner system in such a landfill, the greatest driving force, or gradient, acting on the leachate is gravity: Whatever leachate comes out of the bottom of the liner will fall by gravity into the subsurface and the groundwater. In utilizing an inward gradient design concept, the liner system is placed below the groundwater surface after the design engineer determines, though calculations, how deep to put the landfill in relation to the groundwater level. The groundwater then actually creates a positive pressure on the outside of the liner system. Because that positive pressure is greater than the pull of gravity out of the liner, the pressure exerted by the groundwater allows some of that groundwater to move through any hole in the liner into the liner system where it can be collected and removed by the leachate collection and removal system. In the event of a leak through a liner system at a landfill which utilizes the inward gradient design, instead of the leachate escaping the landfill, groundwater flows into the liner system because the pressure of the water flowing into the landfill is greater than the pressure of fluid leaving the landfill. This results in there being present more liquid in the liner system than would otherwise be the case. Therefore, the liner system must be designed to collect and treat that increased volume of leachate. The inward gradient concept may be used to prevent groundwater pollution because, with ground water flowing into the liner system, leachate does not escape from the landfill and never gets into groundwater. Initially, in order to construct an inward gradient design landfill, it is necessary to artificially and temporarily depress the groundwater level at the landfill site, using a dewatering system. Several technologies are available for constructing an effective dewatering system. At an inward gradient landfill, it is necessary to continue to dewater to depress the groundwater level until enough waste has been placed in the landfill to counteract the force of the groundwater pushing up on the landfill liner system. When enough waste has been placed in the landfill, dewatering will no longer be necessary and the goundwater level will be restored, creating a true inward gradient. In an inward gradient landfill, the waste in the landfill does not come in contact with groundwater; rather, groundwater enters into the liner system where it is contained, collected and removed. The waste in the landfill does not escape from the liner nor does the leachate collected in the liner system escape into the environment. In an inward gradient landfill, the leachate in the liner system is more concentrated in terms of its chemical constituents than the groundwater below the liner system. This creates a concentration gradient, a ground force which tends to push the leachate from inside the liner system out through the liner and into the lower concentration side, the groundwater. However, in a properly designed inward gradient landfill, the design takes that concentration gradient factor into account and employs the upward gradient of the groundwater to counteract the concentration gradient in the leachate, since the upward gradient of the groundwater will be greater the deeper the landfill liner system is placed below the groundwater level. Inward gradient landfills have been designed, constructed, and operated in many places in the United States and in Canada. In several states, inward gradient landfills are required as the preferred design of first choice. Expert witnesses for both WMIF and DER agreed that the inward gradient design concept is a well established technology and is not new or innovative technology. Slurry walls are a containment design concept used in some landfill construction which employs the inward gradient design concept. A slurry wall consists of a trench-cut into the ground down to the depth at which is encountered a continuous layer of low permeability material underlying the site. This trench is backfilled with a low permeability mixture of materials. The trench is constructed on all four sides of the landfill to create a low permeability barrier around all sides and connected to the bottom of the landfill. The groundwater is pumped out of the area enclosed by the slurry walls so that the surface of the groundwater is artificially depressed within them. In a landfill design employing the slurry wall concept, the groundwater level is lower inside the slurry wall than it is outside, thereby creating an inward gradient and causing leakage of groundwater into the landfill instead of leakage of leachate from the landfill into the environment. The slurry wall system is an effective design, which is in use in the state of Florida. Not all sites are appropriate locations for an inward gradient design landfill. Hydrogeologic and soil conditions vary greatly around and across the state of Florida. In many areas, soils are sandy and provide little attenuation of contaminants. Also, in many areas, groundwater levels are close to land surface. In determining whether an inward gradient design is appropriate at a given site, an would consider the type of subgrade soils, the terrain, the degree of fluctuation in groundwater levels over time, the type of groundwater involved, and the financial capability of the landfill owner/operator to build and operate the inward gradient design landfill. The use of the inward gradient design concept in landfill construction would be inappropriate in southern portions of Florida, particularly in the Biscayne aquifer area. However, in many other areas of Florida it would be appropriate to consider utilizing the inward gradient design concept. One of the primary purposes of Chapter 17-701, Florida Administrative Code, is the protection of groundwater by establishing design criteria for landfills, which criteria are protective of that resource. Chapter 17-701, Florida Administrative Code, both as proposed and as adopted by the ERC, provides design criteria which must be met in the case of each proposed new landfill; however, there is no single standard, uniform design mandated by DER's rules. A variety of designs could be used to satisfy the design criteria of Chapter 17-701, Florida Administrative Code. The challenged sentence was added to Chapter 17- 701, Florida Administrative Code, because some members of the ERC expressed their opinion during the rule adoption hearing, based on their "gut" reaction, that there should be some language in the rule which prohibited the construction of landfills within groundwater. Those ERC members asked DER staff to propose language for insertion into the rule that would prohibit such construction. In response to that request Department staff proposed the challenged sentence for inclusion in the rule. The language which the Department had proposed in the January draft of the rule contained qualifiers which would have enabled a permittee to establish that its design of a landfill was capable of groundwater protection to an equivalent degree in relation to other criteria in the rule. However, the Department did not include that qualifying language in the sentence that it proposed to the ERC for inclusion in the rule because the ERC did not want any exceptions to the prohibition. The sentence added to Rule 17-701.050(5)(d)1, Florida Administrative Code, and which is ohallenged in this proceeding, forecloses at least one possible landfill design concept. The challenged sentence precludes the use of the inward gradient design concept which, at least at some bites and as agreed upon by both WMIF and DER experts, is the landfill design that would result in maximum groundwater protection. In the proper hydrogeologic setting, it can be demonstrated that an inward gradient design landfill provides not only equal but greater protection for the' environment than an outward gradient design landfill built above the groundwater level. There are no engineering papers, reports, studies, or data which would support a prohibition of the use of the inward gradient design concept at a landfill from an engineering standpoint. Instead, there is a large volume of technical information which would support the use of the inward gradient design from an engineering standpoint. The challenged sentence is not indicative of good environmental engineering and will not serve to meet DER's goals or the goals of the State in maximizing groundwater protection. DER has not conducted, prepared, or obtained any studies, data, reports, or other research in order to assess the validity or justification of the challenged sentence, and its employees conceded that there is no technical justification behind the challenged sentence. Both of the Department's employees testified that in their opinion, it was possible for a landfill Lo be designed with the bottom of the liner below the 10-year seasonal high groundwater level and for groundwater to be qualify protected from infiltration of leachate into the groundwater at that site, because of the operation of the inward gradient design principle, and that they were not aware of and did not consider any studies or scientific data that would contradict that opinion. The Department has never made a determination that the inward gradient design concept is not viable or that a landfill designed in that manner would be incapable of protecting groundwater to an equivalent extent in regard to other criteria in Chapter 17-701, Florida Administrative Code. In fact, both of the Department's representatives testified that they believed that the inward gradient concept is viable and that prohibiting use of this design option is illogical. Moreover, at the ERC meeting, Department representatives attempted to convince members of the ERC that the inward gradient design concept was viable' and that perhaps a greater degree of flexibility in the rule would be appropriate. The Department had no data and no studies on which to base a determination as to the specific high groundwater level which should be incorporated into the prohibition requested by the ERC. The selection of "the 10-year seasonal high groundwater level" as referenced in the challenged sentence was based on a spur of the moment decision or a "gut" feeling. The 10- year standard was selected arbitrarily because it wasn't too short or too long. At any given site, it will be very difficult to determine the 10-year seasonal high groundwater level. DER does not maintain data on the 10-year seasonal groundwater level at locations around the state, and insufficient information is available from other sources to accurately determine the 10-year seasonal high groundwater level at most locations around the state. At best, broad approximations of the seasonal high groundwater level at a particular site can e extrapolated from data available in the region in which the site lies. DER's representative acknowledges that the best approximation extrapolated from the scanty data could be considerably off from actual groundwater level. If the challenged sentence is deleted, Chapter 17- 701, Florida Administrative Code, still would require that a new landfill and its liner system be designed to maximize the integrity of the liner system and minimize the potential for infiltration of leachate into groundwater. Nothing in the rules adopted by the ERC would prevent the groundwater level from rising above the 10-year seasonal high groundwater level and coming into contact with a liner system constructed above that level since id-he challenged sentence does not specify a distance that the bottom of the liner would have to be constructed above the 10-year seasonal high groundwater level. Because at specific locations and times and under some conditions the actual groundwater level will exceed the 10- year seasonal high groundwater level, it is likely that the bottom of the liner will come in contact with groundwater on some occasions since the inclusion of the challenged sentence allows landfill liners to be designed and constructed in a zone which will be intermittently wetted. When that happens, the groundwater will put pressure on the liner system. Since the liner system would not be designed to contend with the force exerted by the groundwater, as is the case in an inward gradient design, over time, that stress on the liner would tend to weaken the liner. Despite the challenged sentence in Rule 17- 701.050(5)(d)1, Florida Administrative Code, the Department theoretically could consider approving the use of the inward gradient design concept for a landfill at a particular site under the alternate design procedures set forth in Rule 17-701.078, Florida Administrative Code. However, approval of an inward gradient design for a particular landfill using the alternate design procedure in the rule, would required the Department to approve a design specifically prohibited by the rule. As a practical matter, in reviewing an inward gradient design at a specific site, the Department will be faced with a proposal that flies directly in the face of its rule. Even if approved, that alternate design would be very difficult to defend in an administrative proceeding challenging the issuance of the permit and the approval of that alternate design. In order to obtain approval of an alternate design, an owner/operator of a landfill would have to demonstrate that it would suffer a hardship if the alternative design was not approved. Primarily, the type of hardship which would have to be demonstrated is an economic hardship. In many cases it would be difficult for the owner/operator to demonstrate an economic hardship if it is prohibited from using the inward gradient design concept. Both of the Department's employees testified that in their opinion, the very fact that the ERC expressed an intent to prohibit construction of landfills below groundwater level, and included the challenged sentence in the rule to accomplish that intent, would make it very difficult for a permittee to obtain approval of an inward gradient design concept as an alternate procedure under the rule. In fact, given that every landfill permit proposed for issuance by the Department in recent memory has been challenged in administrative proceedings, and that each of those proceedings has been a fairly arduous process for both the Department and the permittee, it would be especially difficult to defend a permit approving an alternate design which was specifically prohibited in the rule. Both of the Department's witnesses agreed that if the challenged sentence was not in the rule, both the permittee and the Department would have an easier time approving an inward gradient design at a particular landfill. Prior to the ERC meeting on April 12, 1990, DER prepared an Economic Impact Statement (EIS) regarding its proposed revisions to Chapter 17-701, Florida Administrative Code. The EIS did not provide a cost/benefit analysis of the challenged sentence, as required by Section 120.54(2), Florida Statutes, because that provision was drafted after the EIS was prepared. It is uncontroverted that a permittee would incur an economic impact because of the challenged sentence in the rule, prohibiting the use of the inward gradient design concept, because that would result in a diminution of landfill capacity available at a given site.
Recommendation Upon the foregoing Findings of Fact and Conclusions of Law, it is ORDERED that the sentence, "The bottom of the liner shall be constructed above the 10- year seasonal high groundwater level contained within proposed DER Rule 17- 701.050(5)(d)1, Florida Administrative Code, is an invalid exercise of delegated legislative authority.

The Issue Based upon the evidence presented at the hearing, the primary factual issues are as follow: whether the application for a variance was a minor deviation from the standards established by Rule 10D-6.45(3), Florida Administrative Code; Whether the Petitioner clearly showed that the public health would not be impaired or that pollution of surface or groundwater would not result; and whether the petitioner would suffer a hardship if the variance were not granted. Both parties submitted posthearing findings of fact, which were read and considered. Those findings not incorporated herein are found to be subordinate, cumulative, immaterial, unnecessary, or not supported by the evidence.
Findings Of Fact On January 11, 1983, the petitioner, George F. Conley, applied for an individual sewage disposal system (septic tank) permit to the Hillsborough County Health Department, a part of the Respondent, Department of Health and Rehabilitative Services. This application appears to be for one of two adjoining lots owned by the Petitioner. By letter dated January 11, 1983, signed by William Dickson of the Hillsborough County Health Department, the petitioner's application was denied. The grounds for denial, as stated in Dickson's letter received as Joint Exhibit 1, were lack of sufficient soil depth and severely limited soil. The Petitioner applied for a variance as provided for in Joint Exhibit On January 24, 1983, a hearing was held before the Variance Board pursuant to Section 10D-6.45, Florida Administrative Code. The transcript of said proceeding reflects that the Board unanimously recommended approval of a "mound" septic tank system which would be elevated at least three feet above the existing grade and be oversized. The application for the variance was for one of the Petitioner's two lots; however, the Board's approval was for a variance on both lots. On or about February 1, 1983, Robert Roush, soil conservationist for the United States Department of Agriculture, conducted a soil identification at the Petitioner's proposed construction site. In Roush's letter of February 1, 1983, he reported that test borings indicated the soil at the test site was Bradenton fine sand, thin surface phase, as described in the Soil Survey for Hillsborough County, Florida, Series 1950, No. 3, of September 1958, USDA--Soil Conservation Service. Roush further reported that the Soil Survey Supplement of the USDA--Soil Conservation Service, Seffner, Florida, June 1981, indicated said soil constituted a severe hazard, with wetness being the chief limiting factor. By letter dated February 14, 1983 (Joint Exhibit 5), Stephen H. King, State Health Officer, denied the Petitioner's request for a variance for a septic tank system in relationship to both lots. Dr. King's letter stated in pertinent part as follows: granting of variances from established standards is for relieving or preventing excessive hardships and may be granted where minor deviations will not result in pollution of ground- water or impairment of public health. The Hillsborough County Health Unit has stated that a history of failing systems has been noted in the Ruskin area in soil conditions similar to those existing on your lots. Although the Review Group for Individual Sewage Disposal has recom- mended approval of your variance appli- cation, the site specific conditions on your lots, including soil, seasonal high water table and potential flooding conditions, do not appear suitable for the installation of onsite sewage dis- posal systems. Therefore, I must hereby disapprove your request for variance. The Petitioner timely requested a formal hearing on the denial of his application and request for a variance. In the manner by which the water table is computed under the Respondent's rules, the perched water table normally lies at six inches beneath the surface. C. K. Satyapriya was accepted as an expert in civil engineering and geo-technical engineering. Satyapriya described a mound septic tank system for treatment of gray water waste which met the minimum criteria for soil depth as provided in Rules 10D-6.42(12) and 10D-6.45(2), Florida Administrative Code, and could be installed on the site. See Hearing Officer's Exhibit 1. According to Satyapriya's plan, the existing soil would be excavated, a soil with good absorptive qualities would be used as fill in the area excavated, and additional material added to form a mound. Black water would be dealt with separately, retained onsite, and removed from the site for disposal. The pictures taken by the parties and the weather information presented by the Petitioner indicate that January/ February 1983 was a period of exceptionally high rainfall in the Tampa Bay area within which Ruskin is located. The system described by the Petitioner's expert would not have flooded for any significant period during these exceptional conditions. Dickson, a sanitarian with the Hillsborough County Health Department for 22 years and supervisor in the area of administration of septic tank applications, was called to rebut Satyapriya's testimony. Dickson had worked for many years in the area of Ruskin, Florida, where the Petitioner's lots are located. Many problems with septic tanks, including flooding and breakdown of the system, occur in this general area because of a layer of impermeable material near the ground surface. This impermeable layer prevents the waste water from dissipating within the drainfield and, when it rains, acts as a basin to retain rainwater above the impermeable layer. Any excavation into, but not through, this impermeable layer traps the water, creating a bathtub effect. The bathtub effect creates problems when the area floods during heavy rains and the replaced material within which the drainfield has been installed becomes saturated. When saturated with water, the septic tank system is unable to accept any more waste product, which in turn backs up sewage into the waste line of the home or business. These conditions constitute a health hazard to the public and a potential health hazard to ground and surface water. Dickson interpreted the rule to require digging through the impermeable layer to permit the water to move down into absorptive material below. The existing water tables in the area of concern are a result of the subsurface impermeable layer described above. This layer retains the water above the layer and prevents it from sinking deeper into the ground. It also forms a cap on top of the water beneath it, which water table may be restrained by it. The resultant water pressure causes artesian wells. Therefore, this impermeable layer causes two water tables in this area, one perched on top of the impermeable layer and another underneath the impermeable layer. It is the water table perched on top of the impermeable layer which lies close to the surface. However, the impermeable layer keeps this "surface" water from mixing with water beneath the layer. Drinking water is not obtained from the upper water table, but from the water table under the impermeable layer. The impermeable layer would not be penetrated by the proposed gray water system, which meets the Respondent's guidelines of 54 inches beneath the drainfield. According to Dickson, a mound made of absorptive materials would soak water up into the mound from the groundwater level. This would saturate the drainfield in the mound above the normal water table. Satyapriya testified that the use of course material would prevent this absorption through capillary action. Satyapriya's testimony is accepted as the most credible, and the gray water treated in the mound would not pollute the upper water table.
Recommendation Having found it is a minor deviation from the rules to install a septic tank system in an area of limited soil; having found the denial of the Petitioner's application is a substantial hardship; having found that a mound system can be installed within the physical limitations provided in the rules; and having found that a system separating gray and black water properly installed would not endanger public health or pollute water, it is recommended that the Respondent approve an alternate system for one of the Petitioner's lots, constructed in accordance with plans certified by a Florida engineer to be installed in accordance with the approved design and installation requirements to provide for onsite treatment of gray water waste and retention and removal of black water waste from the site for disposal.

The Issue The issue for consideration in this proceeding concerns whether the Petitioner is entitled to an on-site sewage disposal system ("OSDS") permit authorizing installation of an OSDS on property which Petitioner owns near the Suwanee River in Dixie County, Florida, in accordance with Section 8l.272, Florida Statutes, and Chapter 10D-6, Florida Administrative Code.
Findings Of Fact The Petitioner is an owner, by joint tenancy, of real property located in Dixie County, Florida, more particularly described as part of Government Lot 1, Section 4, Township 11 South, Range 13 East; closely proximate to the Suwanee River at a location generally known as "New Pine Landing". The surrounding property is characterized by homes and mobile home,;, which have OSDS's installed and operating. The subject property has no improvements constructed thereon, although the Petitioner intends the placement of a 12X60 foot mobile home, containing two bedrooms and one bathroom. There is no OSDS of any type installed on the property at the present time. The subject property is approximately 18.5 acres in size. It was purchased on January 17, 1990, but the property in question has never been platted. On March 20, 1990, the Petitioner made application for an OSDS permit for the aforesaid property, which was denied by the Respondent's letter of denial dated April 23, 1990. The Petitioner was not afforded the opportunity to pursue an informal variance application through the variance procedure set up by the statute and rules cited hereinbelow. Rather, the Respondent, in its denial letter, indicated that, because of the perceived effect of the Governor's Executive Order, discussed hereinbelow, no variances were being granted and the variance procedure would be "bypassed" in favor of affording the Petitioner a formal administrative hearing before the Division of Administrative Hearings concerning the permit denial. The Petitioner testified generally concerning the character of the property in question and the general nature of the terrain and vegetation. The property is characterized by a wetland or swampy area at one end of the property and, in the area of the proposed installation site, the ground elevation is higher, with a benchmark elevation of 8.8 feet above mean sea level ("MSL"), as established by Herbert H. Raker, certified land surveyor, and depicted by Petitioner's Exhibit 2 in evidence. The Petitioner offered no testimony concerning the ground water levels, other than to say that at one point in time, he dug a three-foot-deep hole on the subject property near the septic tank installation site and observed no water in the hole. His testimony did not indicate at what season of the year the observation was made nor whether conditions were wet or dry at the time. The only concrete evidence concerning ground water level at this installation site was that offered by the Respondent, which indicates that the ground water level at the time of the site evaluation was 42 inches below the surface of the property in question at the proposed installation site and, through observation of "mottling1, of the soil, indicating the presence of dampness, that the wet season water table is 12 inches below the surface of the property. Likewise, the Petitioner professed to have no knowledge of the ten-year flood elevation for the property. The Respondent's evidence, derived from materials submitted by the Petitioner in furtherance of the application, consisting of a report from the Suwanee River Water Management District, establishes that the ten-year flood elevation is 14 feet above MSL for Suwanee River Mile 29, which corresponds to the location of the subject property. The property is also located within the regulatory floodway administered by the Suwanee River Water Management District. Rule 10D-6.047, Florida Administrative Code, mandates that before a mounded system for on-site sewage disposal can be installed, a certification by a registered engineer would be necessary to determine that installation of such a mounded system would not raise the level of the "base flood". No such engineering testimony or evidence has been offered in this proceeding, however. The Petitioner further testified in a general sense that it would be a hardship not to be able to) install the OSDS on the property, given the money paid to purchase the property and the intent by the Petitioner to use it for a residence. The Petitioner has no use for the property without being able to use it for a residence. The Petitioner, however, did not offer any testimony or evidence concerning alternatives to installing the proposed OSDS, nor did the Petitioner establish that installation of such a system or an alternative system would pose no adverse health effects on the Petitioner or members of the general public nor that it would pose no degradation to the surface or ground waters involved for purposes of the Petitioner establishing entitlement to a permit or a variance It should be remembered, however, that the Petitioners were not accorded the opportunity to avail themselves of the variance procedure because of the Respondent's interpretation of the Governor's Executive Order 90-14, which it opines precludes it from granting any variances, or permits for OSDS within the ten-year flood elevation. This leads to its advising the Petitioner that to apply for a variance in this instance would be futile. The Governor's Executive Order, which incorporated the "Suwanee River Task Force" recommendation to preclude such system; beneath the ten-year flood elevation was entered on January 17 1990. The Respondent has, in effect, interpreted that Executive Order as precluding it from exercising its discretion to entertain and grant or deny variance applications.
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 the Petitioner's application for an OSDS permit without prejudice to the Petitioner applying for and seeking a variance from the statutory and rule requirements related to permitting, for the reasons found and concluded above; and without prejudice to pursuing an OSDS permit application at a later time should the Petitioner become able to demonstrate that alternative methods of treatment and disposal of the sewage effluent in question can feasibly be performed within the bounds of the standards enunciated in the above-cited statutes and rules concerning on- site sewage disposal permitting.

The Issue Schofield Corporation of Orlando has applied to the Department of Environmental Regulation for a permit to construct and operate a Class III trash/yard trash landfill in Orange County, Florida. The issues are whether the applicant is entitled to the permit and, if so, what conditions should attach. Also at issue is Schofield Corporation's motion for attorney's fees and costs, pursuant to Section 403.412(2)(f), F.S.
Findings Of Fact The applicant, Schofield Corporation of Orlando (Schofield), owns the proposed landfill site and existing permits for the site. The proposed site is located in West Orange County, southwest of the intersection of State Road 545 and Schofield Road on the west half of the northwest quarter of section 32, township 23 south, range 27 east, comprising approximately sixty acres within a larger eighty-acre parcel. In some undetermined distant past the site was cultivated in citrus. It is currently being excavated as a borrow pit. The materials proposed to be placed in the landfill include trash, yard trash, construction and demolition debris and clean debris, as defined in DER Rule 17-701.020, F.A.C. The northern half of the site is flat and will be used first for the composting operation. The southern excavated portion of the site will receive the permitted fill material until it is flattened. Then, the two functions will alternate; the composting will occur on the south, and the north end will be excavated to receive fill. The proposed facility will be operated by Chambers Corporation, a nationally recognized waste management company with approximately 20 years of experience in solid waste management. The landfill site will be completely fenced, with a gate entrance mid-site between the landfill and compost area. The gate will be locked when the facility is not in operation, and will be patrolled by security personnel 24 hours a day. "Spotters", or inspectors will be employed to examine incoming waste loads at the gate, from a high gantry, and at the place where the waste is deposited. The loads will be monitored by a television camera, and all haulers will be under contract. The landfill will not accept loads from trucks coming off the road looking for a place to dump. Receptacles will be maintained on site to receive errant non-permitted waste that is found in a load, and that waste will be properly disposed of elsewhere. Schofield has several permits related to its proposed operation. These include a type III landfill permit from Orange County, a compost facility permit from DER, a general construction and demolition debris landfill permit from DER, a surface water management permit from the South Florida Water Management District, and a permit to excavate or mine from the Florida Department of Natural Resources. Schofield also has a contract to receive yard waste from Orange County. The initial term of contract requires at least ten percent of the yard waste to be composted or recycled, with the percentage amount to be renegotiated in subsequent contract renewals. In the hierarchy of landfills, DER considers Class III the least environmentally sensitive. Problems with unauthorized waste and with water quality occur more frequently with Class I landfills, defined as accommodating more than twenty tons a day of residential garbage. In this case DER has proposed to grant Schofield its Class III permit without the requirement of a bottom liner or a leachate or gas control system because of the nature of the waste that will be accepted and because of the rigorous controls, described above, to avoid receiving unauthorized or hazardous waste. The Petitioners are an individual and a homeowners' association representing a residential area approximately a half mile south of the proposed site. Petitioners contend that the applicant's data is insufficient to provide reasonable assurances that water quality standards will not be violated. Petitioners contend that the landfill, if approved, should be required to have a liner to prevent leachate from polluting the groundwater. They further contend that the groundwater monitoring plan submitted by the applicant is inadequate to detect vertical movement of contaminated leachate into the Floridan aquifer, a major source of water supply in Orange County. Hydrogeology The site of the proposed landfill is within a high recharge area. Water percolates rapidly though the soil, moving downward into the aquifer, and laterally off site. The site is considered Karst terrain, underlined with limerock. There is evidence of relic sinkholes, thousands of years old, but there is a low probability of future open sinkhole development. The geology in the area of the site provides adequate structural support for the proposed facility. An aquifer is generally defined as a unit of material which contains water and can give up a sufficient amount of yield to provide some productive flow for pumpage. Below the site there are two aquifers: the shallow water table, or surficial aquifer, containing clean well-drained fine sands, about 70 feet down; and the Floridan, primarily limestone, encountered at a depth of approximately 115 feet. The two are separated by a confining layer of less permeable sands and clay. Flow in the Floridan at the site is primarily from the west to east. Flow in the surficial is also generally from west to east, but the Petitioners theorize, and have presented competent supporting evidence, that there are fissures in the confining layer, allowing some internal drainage within the site, causing surficial water to flow vertically into the Floridan, rather than laterally off-site in an eastward direction. Based on recent data taken from two piezometers installed near the middle of the site, the applicant's hydrogeologist, James Golden, concedes that "mounding" exists along the eastern boundary of the site, reflecting some flow westerly back into the interior of the site. Petitioners' theory regarding internal draining of the site is based in part on data as to groundwater elevation. Groundwater elevation or high groundwater table is the elevation at which water stands on a continuous surface under the site. Jammal and Associates is a consultant firm which has done field studies of this and neighboring sites in the past, for various purposes. Some open bore readings taken by Jammal and Associates in a 1983 study for the Orange County Rapid Infiltration Basin project indicate groundwater table levels on site up to 126 feet, National Geodetic Vertical Data (NGVD). Open bore readings are less reliable than cased hole readings; due to collapses within the hole, artificially high readings are sometimes obtained. Data from the applicant's consultants reveals groundwater tables at 96-98 NGVD. This data was most recently obtained in December 1991 from sealed and surveyed piezometer casings, but not from the area of the site where Jammal's higher readings were obtained. Although it may be conjectured that Jammal's high readings are anomalous, additional sealed borings need to be obtained before the anomaly is confirmed. Groundwater elevations are significant also to determine the depth to which the landfill may be excavated. Based on its December 1991 readings, obtained after the application for permit was filed, the applicant agreed to raise the proposed bottom of the landfill to approximately five feet above the level of the estimated high (wet weather) groundwater table in the area. Water Quality and Monitoring Specific conditions of the proposed permit include DER's requirements that Class GII water quality standards be met at the boundary of the zone of discharge, in accordance with Rule 17-3, F.A.C. The zone of discharge for this facility is a three-dimensional volume defined in the vertical plane as the top of the ground to the base of the most surficial aquifer, and horizontally 100 feet from the edge of the waste-filled area, or the property boundary, whichever is less. The groundwater monitoring plan proposed by the applicant includes one upstream monitoring well on the west side of the site and five wells along the east side of the site, with an additional well at the south, between the project and the Petitioners' residential area. The wells extend down into the upper zone of the surficial aquifer, but not into the deeper limestone Floridan. The downstream wells should detect any contamination in the surficial aquifer flowing from west to east at the zone of discharge. However, they will not pick up contamination draining internally within the site and into the Floridan. Such contamination is possible, even though leachate from Class III- type wastes is expected to be relatively benign. Volatile organic carbons (VOCs) have not typically been a problem in Class III landfills, unless those landfills were previously operated as Class I sites. Secondary drinking water standards for certain metals have been violated at some Class III sites, but such violations are often related to the problem of sampling newly-installed wells. From DER records, Petitioners presented evidence of consistent drinking water quality standard violations in Class III landfills. That such violations can occur in Class III landfills is clearly established. It is not so clear that such violations will occur in this facility, given the proposed controls on load content. However, even acceptable materials will not avoid the production of leachate or gas. Within demolition waste there are chemically bound components which are inseparable, for example, creosote and other preservatives, glues, paints, resins, varnishes and stains. The lignin, tannins and volatile organic acids which are produced when wood decomposes alter the pH of the groundwater. As the water becomes more acidic, heavy metals that were typically bound up in the waste or in the soil, are released in soluble form and travel with the water. The decomposition process occurring in the construction and demolition waste is enhanced by the addition of yard trash which becomes the food source for the biodegradation. Summary of Findings and Proposed Permit Conditions If, as applicant suggests, all groundwater moves primarily from west to east within the site, given the proposed operational controls and the proposed monitoring plan, reasonable assurances have been provided that water quality standards will not be violated beyond the zone of discharge. That is, any contamination likely to occur will be contained within the surficial aquifer and within the 100 feet or property line horizontal boundary. Transmissivity of the surficial aquifer is low enough to allow mixing of the leachate before it reaches the zone of discharge. The Petitioners, however, have presented credible evidence sufficient to question the groundwater flow premise and sufficient to require additional conditions on the permit. If leachate reaches the Floridan through fissures in the confining layer, it will move rapidly off site. In its proposed recommended order DER has suggested additional permit conditions and in its adoption of the proposed recommended order, the applicant has accepted those additional permit conditions. Those permit conditions recognize the fact that data presently provided by the applicant is insufficient to overcome the evidence by Petitioners as to the hydrogeological characteristics of the site with the possibility of internal drainage and vertical intrusion of contaminated water into the Floridan aquifer. The proposed recommended order provides this finding: ...that the ground water monitoring plan as proposed in this proceeding is adequate, provided that there be added to the permit conditions that the permittee conduct appropriate water table testing with cased piezometers during the next wet season to determine whether ground water flow is internal within the site and therefore not intercepted by the present ground water monitoring wells. The permittee shall consult with DER and get approval for the location and construction of these wells prior to their installation. The results shall be immediately submitted to the DER. The ground water monitoring requirements should be modified if necessary at that time pursuant to Rule 17-28.700(5) to assure proper monitoring at this site. (DER proposed Recommended Order, p. 17) The ground water monitoring plan modification suggested by DER is that deeper monitoring wells, into the Floridan aquifer, be required if the additional testing reveals the likelihood of internal on-site ground water drainage. These conditions are still inadequate since they lack specificity with regard to the extent of testing, the location and construction of the wells, and the amendments to the monitoring program to be required if internal drainage is confirmed. Moreover, the proposed conditions fail to address the possibility that the permit should require a liner for the landfill if the data to be obtained reveals the likelihood that contaminates will penetrate into the groundwater of the Floridan. Monitoring programs, however effective, only predict or detect problems; they do not remediate them. Groundwater contamination by landfills is not quickly and easily reversed. Unlike discharges from other facilities such as spray application or deep well injection, the leachate from a landfill is not "turned off". Without the additional data which all parties agree is needed, it is impossible to determine what additional conditions, if any, should be required or what amendments, if any, need to be made to the applicant's proposed monitoring plan.

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 issues considered at final hearing were those issues set out in Petitioners' Amended Petition For A Formal Hearing. At the conclusion of the final hearing the parties were given an opportunity to file a proposed recommended order and memorandum in support thereof. Such memorandum and proposed recommended order was received by the Hearing Officer from the Department of Environmental Regulation on November 10, 1976, from Leon County on November 12, 1976, and from the Citizens' Committee to Preserve Lake Lafayette on November 15, 1976. Having fully considered the matters presented herein, the Hearing Officer enters the following:
Findings Of Fact Respondent, Leon County, Florida, has applied for a construction permit to construct a sanitary landfill in Sections 4 and 5, Township 1 South, Range 2 East, Leon County, Florida. The proposed site consists of 79.9 acres off of U.S. Highway 27 South. The application is in proper form and contains all information required by the Department of Environmental Regulation. The area to be served by the proposed sanitary landfill is Leon County, Florida, with a projected average population of 155,200. The responsible operating authority as set forth in the application is Leon County. The evidence presented did not establish that the proposed sanitary landfill will attract high concentrations of rodents, insects, or birds which would do serious damage to the land and crops surrounding the site or which would adversely affect the health and welfare of the residents near the site. The application proposes a program for the extermination of any rats discovered on site and further proposes that the working faces of the landfill area will be kept as small as possible with all exposed waste materials covered as frequently as practical to minimize the problem of flies and insects during hot, humid periods. Evidence was presented indicating that construction of the proposed sanitary landfill site could adversely affect surrounding property value. However, the evidence was not sufficient to conclusively establish the extent of this affect nor the time at which it would occur or for which it would endure. As designed the proposed sanitary landfill would not cause any solid waste to be disposed of by being placed in or within 200 feet of any natural or artificial body of water or on the watershed of any surface water supply. Lake Lafayette is hydraulically connected to the Floridan Aquifer. The proposed sanitary landfill site is located at least 500 feet from the flood prone area of Lake Lafayette and 1,000 feet from Lake Lafayette proper. As designed the proposed sanitary landfill will not cause any solid waste to be disposed of by being placed in a sink hole or in the immediate area thereof. Solid waste will be disposed of by being placed in a trench and covered over with successive lifts similarly covered. There are no active sink holes on or in the immediate area of, the proposed sanitary landfill site. Three ponds exist in the immediate vicinity of the site, one of which is to be used for surface water runoff. These ponds were probably formed by past sink hole activity but from the site topography and water elevations it appears that the ponds are now stable and are probably not hydraulically connected with the Floridan Aquifer. No limestone or gravel pits exist on site. The entire proposed site is well above the +50' MSL contour line below which are found flood prone areas in the vicinity of the site. The water table of the site is more than 5 feet below normal ground surface. As designed the proposed sanitary landfill will not require the disposal of solid waste in an area immediately adjacent to or within the cone of influence of a public water supply. As designed the proposed sanitary landfill will not require the disposal of solid waste within 200 feet of any habitation or place of business served by a public water supply system or within 1,000 feet of any habitation or place of business served by an individual potable shallow water supply well with the following exceptions. There are three wells located on the property which would be owned by Leon County that may be within 1,000 feet of the disposal site for solid waste. Of these three wells one has been abandoned and will be sealed. A second is located south of the proposed site at an existing house and will be used as a source of non-potable water and for monitoring the potable aquifer. The third well is located on the northwest portion of the county property and will be maintained as a standby source of potable water. There are two other wells located on the property to be owned by Leon County which are more than 1,000 feet from the proposed disposal site for solid waste and could be used to monitor the Floridan Aquifer. There is a well which serves a private residence and farm located plus or minus 1,200 feet west of the proposed site for the disposal of solid waste. No solid waste shall be disposed of in any area open to public view from any major thoroughfare. The proposed site in not on any public highway, road, alley or the right-of-way thereof. The Lake Lafayette drainage basin is approximately six miles long elongated in a west-northwest, east-southeast direction. The width varies between one-quarter to one-half mile. The western end of the basin contains many sink holes which probably have open connections to the underlying bedrock. The eastern end of the basin, near the proposed landfill site, is swampy and contains many cypress trees. The Lake Lafayette drainage basin appears to be an area of recharge to the Floridan Aquifer. The proposed sanitary landfill site is not located in the Lake Lafayette drainage basin. The engineering firm of Ardaman & Associates, Inc., conducted a subsurface investigation of the hydrologic and soil conditions at the site of the proposed sanitary landfill. As part of their investigation they performed ten soil borings and installed seven deep ground water monitoring wells. The results of the investigation of Ardaman & Associates, Inc., indicates a low probability of sink hole occurrence. In the course of their investigation, Ardaman & Associates, Inc., discovered a depression in the ground water level at Test Hole No. 9. The significance of this ground water low is that it may be a localized area of recharge. However, as shown by the testimony of the engineers who conducted the investigation for Ardaman & Associates, Inc., as well as by the report of their investigation, this depression creates no realistic danger with regard to the introduction of pollutants into the aquifer or ground water supply, so long as no putrescible wastes are placed within a distance of 1,000 feet of Test Hole No. 9. The hydro-geologist testifying on behalf of the Petitioners stated that he believed the radius of influence of the depression at Test Hole No. 9 may actually be less than 1,000 feet and that maintaining 1,000 feet distance from Test Hole No. 9 is a conservative distance. As designed, the proposed sanitary landfill will not dispose of any solid waste or other putrescible waste within 1,000 feet of Test Hole No. 9. The soils found on the proposed sanitary landfill site are of low permeability and suitable for a sanitary landfill. The low permeability of the soils will limit both the lateral and vertical seepage of leachate. The vertical flow of potential leachate to the Floridan Aquifer has been estimated at a rate of 1.0 to 1.5 feet per year. The lateral flow rate of such leachate through the soils overlying the bedrock in the Lafayette drainage basin has been estimated at the rate of 2 feet per year. As has been noted above, the proposed sanitary landfill site is located approximately 1,000 feet from Lake Lafayette, and 500 feet from the +50' MSL contour line which has been used to describe the perimeter of the flood prone area of the Lake Lafayette drainage basin. At the estimated flow rate it would therefore take several hundred years for any leachate produced by the sanitary landfill to reach the Lake Lafayette drainage basin. The Floridan Aquifer underlies all of Leon County at depths of 100 to 500 feet. As designed the proposed sanitary landfill will have test wells constructed throughout the site to provide a means of detecting any lateral migration of contaminants from the landfill operation should such occur. Periodic samples will be taken from these test wells and analyzed. The monitoring wells will be set up in such a manner that regardless of the direction of flow of subsurface water they will pick up and detect any pollutants that may be passing from the landfill. Some of these test wells will be placed in close proximity to the proposed sanitary landfill site to give early warning of the existence of any leachate flow. If there is any problem with the flow of leachate from the proposed site it will be detected easily within the first five years of operation. Since it would take several hundred years to reach the Lake Lafayette drainage basin at the estimated flow rates this should provide adequate warning and reaction time for the alleviation of any potential pollution problem. A significant flow of leachate is not expected. The existing pond which will receive the surface runoff from the sanitary landfill site is likely of sink hole origin but after a reasonable investigation it appears that the pond is now stable and not hydraulically connected to the Floridan Aquifer. It is estimated that the pond can contain at least a 25 year storm rainfall though there might be some flooding from the pond in a 100 year storm rainfall. As designed, no significant amount of leachate, if any, will reach the surface water runoff retention pond. Petitioners' hydro-geologist did not state that the site is unsuitable for a sanitary landfill. Rather he testified that on the information he had reviewed, which information was that available to the Department of Environmental Regulation, it was his opinion that the Department of Environmental Regulation lacks sufficient information to determine if the proposed site is suitable from a water quality standpoint. Based upon all the testimony and evidence it appears as a matter of fact that the information available to the Department of Environmental Regulation is reasonably sufficient to determine the suitability of the proposed site. There has been no showing of a necessity for alining the proposed trenches which will receive the solid waste. The Planning Director for the Tallahassee-Leon County Planning Department, in a letter to the Department of Environmental Regulation stated that the use of the proposed site for landfill purposes is not inconsistent with the land use plan. He further stated his concern for traffic on U.S. Highway 27, the possible adverse aesthetic impact which he felt could be minimized and his concern that Lake Lafayette be protected from landfill leachate through engineering design. In their Amended Petition Petitioners raised the question of the present zoning of the proposed site. No evidence was presented by Petitioners to show that the site is not properly zoned. Based upon the testimony and evidence presented there appears little possibility that the proposed sanitary landfill will pollute or seriously damage Lake Lafayette, the Floridan Aquifer or any other source of public or private water supply. The proposed sanitary landfill as designed is not likely to cause any significant water pollution or to degrade water quality below those standards set by the Department of Environmental Regulation. None of the prohibitions set out in Section 17-7.04, F.A.C, exist so as to require the denial of the application for a construction permit for a sanitary landfill by Respondent, Leon County. The sanitary landfill criteria set out in Section 17-7.05, F.A.C., have been met by Respondent, Leon County.
Findings Of Fact Respondent, Textron Petroleum Products Company, Inc., has applied for a construction permit to construct a sanitary landfill in Sections 3 and 10, Township 1 North, Range 2 East, Leon County, Florida. The proposed site consists of ninety (90) acres and is approximately 2,000 feet from U.S Highway 90 at Its closest point to that highway. The application is in proper form and contains all information required by the Department of Environmental Regulation. towns and areas to be served by the application are the City," of Tallahassee and Leon County. The facility is designed to serve a population of 135,000 people. Although evidence was presented for the purpose of showing that the City of Tallahassee and Leon County, as governmental entities, do not intend to use the proposed sanitary landfill as an "official" landfill site for those governmental bodies, this evidence did not establish that the area to be served and the population to be served by the proposed sanitary landfill is other than that stated above. The applicant, Textron Petroleum Products Company, Inc. does not have a franchise from any county, municipality or other governmental agency with regard to solid waste resource recovery and management responsibilities. The applicant, Textron Petroleum Products Company, Inc., had not, at the time of hearing, posted a performance bond or other approved security with the agency within whose jurisdiction the proposed site is located. The "owner" as that term is used in Section 17-4.21(1)(d), F.A.C., is the applicant, Textron Petroleum Products Company, Inc. The unrebutted evidence presented,at hearing established that the applicant has a net worth of $1 million and is financially responsible. The evidence presented did not establish any violation of the State Resource Recovery And Management Program set out in Part II, Chatper 17-7, F.A.C. There is a public supply well located in the Homestead Ridge area. This system serves 38 or more customers at an averave rate of about 200,000 gallons per month. The well is located more than 2,700 feet from the site boundary of the proposed sanitary landfill. As found by the Northwest Florida Water Management District, even if the consumption of that well system were increased to 2.16 million gallons of water per month, the drawdown at a radius of 2,000 feet would be 0.13 feet. Therefore, it was concluded that the cone of influence of the public water supply does not extend under the proposed sanitary landfill site. As a condition for issuance of a construction permit the Department of Environmental Regulation proposes the requirement of a monitoring system of wells which would include a deep well located between the proposed site and the Homestead Ridge public supply, the purpose of which would be to detect the potential intrusion of leachate or other contaminants into the public water supply from the sanitary landfill. It is improbable that the proposed sanitary landfill will produce any significant quantity of leachate. However, the application proposes that if monitoring indicates that lechate control is needed, a well point system will be installed in the completed cells and underground pipe drains installed in the new cells. It further provides that, dependent upon the quantities involved, the leachate.will be transported to the City of Tallahassee Sewage Treatment Facilities for disposal or it will be treated on-site by transporting the leachate to the settling pond which will at that time be equipped with suitable aeration and chlorination equipment for treatment of the leachate. The proposed design of the sanitary landfill provides that all final discharge from the sedimentatlon pond will conform to the water quality standards set out in Chapter 17-3, F.A.C, even though this may require the constrjction of treatment equipment by the applicant. The application, at pages 12 and 14,.provides for the equipment to be used on-site in the operation of the proposed sanitary landfill as well as for the method of providing adequate site supervision. No evidence was presented showing these provisions to be other than adequate. The evidence presented did not establish that the utilization of U.S. Highway 90 by vehicles transporting waste to the proposed sanitary landfill would create any unusual 0rincreased traffic and safety hazard. The application, at page 3, proposed the installation of electronic signalization equipment to alleviate any hazard which might be created by traffic using the proposed site. No evidence was presented showing this proposal to be inadequate. According to a letter to Mr. James Barrineau, Leon County Department of Pollution Control, from Mr. Mark Stamps, Assistant Zoning Director, Tallahassee Leon County Planning Department, the proposed site is currently zoned Agricultural 2. The letter further states that an Agricultural 2 zoning allows a sanitary landfill as a permitted use. A small portion of the proposed sanitary landfill site is open to public view from,U.S. Highway 90 which is a major thoroughfare. It was estimated by a witness that the distance to the proposed site from that section of U.s. Highway 90 from which the site was open to public view was one (1) mile. An examination of the plot plan of.the proposed site contained in the application shows that at the closest point, the site boundary is approximately 2,000 feet from U.5 Highway 90. The site is screened from public view from most places on Highway 90 by the existing topography and ground cover.
The Issue Whether permit application SWO 13-5152, should be granted under Chapter 403, Florida Statutes. This case involves the application of Respondents City of North Miami and Munisport, Inc. to Respondent Department of Environmental Regulation (DER) for an operating permit under the provisions of Chapter 403, Florida Statutes, and Chapter 17-7, Florida Administrative Code, to operate a sanitary landfill located in North Miami, Florida. DER granted provisional approval of the application by the issuance of a Notice of Intent to issue the permit on January 27, 1978. Petitioners filed the instant petition of February 13, 1978, challenging the issuance of the proposed permit. Final hearing herein was originally scheduled for April 7, 1978, but at the instance of the parties was continued and reset to commence on October 18, 1978. During the course of the final hearing, 29 witnesses presented testimony, including six public witnesses. (List of public witnesses - Hearing Officer's Exhibit 3) A total of 35 exhibits were admitted in evidence. Three exhibits (Exhibits 5, 13 and 15) were rejected by the Hearing Officer.
Findings Of Fact By application dated November 14, 1977, Respondent City of North Miami, Florida, as owner, and Respondent Munisport, Inc. as the "responsible operating authority" requested Respondent DER to issue a permit to operate a solid waste resource recovery and management facility consisting of 345.90 acres located at 14301 Biscayne Boulevard, North Miami, Florida. The site, known as the North Miami Recreation Development, had been operating as a sanitary landfill under temporary operating permits (TOP) issued by the DER on May 8, 1975 and September 21, 1976. The 1976 TOP provided for an expiration date of July 1, 1977, and contained various conditions designed to give the permittees a reasonable period of time to conform to the DER regulations relative to sanitary landfills. These included standard requirements such as the rendering of reports on the operation of the facility and prohibiting the deposit of raw and infectious waste, or hazardous waste that had not been rendered safe and sanitary prior to delivery. Additionally, the permit conditions required the facility to be so operated that it would cause minimum adverse effects on the environment, such as objectionable odors, contaminated storm water runoff, or leachates causing degradation of surface of ground waters. Further, the permit provided for a three-month review program after its issuance to consider the feasibility of dumping solid waste in 63 acres of submerged land subject to previous filling with clean fill and/or construction debris, filling of land above mean high water with garbage either above clean fill or above trenches filled with wood and construction debris and covered with clean fill, and a six-week period of weekly water quality monitoring at agreed to sites for analysis by both permittees and the Dade County Environmental Resources Management (DERM). The permit further prohibited the placement of refuse waterward of the mean high water line or in trenches cut below the natural ground water table. (Exhibits 1, 4). By letter of January 27, 1978, DER gave notice to the applicant of its intent to issue the requested operation permit for the solid waste disposal facility and stated therein the following reasons for its determination: The solid waste disposal site is in the public interest. The Department feels that the site will not substantially affect the water quality or interfere with the area's wildlife. The applications and plans for this facility have been evaluated and found to be in conformance with Chapter 403, F.S., Chapter 17-4, FAC, and Chapter 17-7, FAC. The letter stated standard conditions to which the permit would be subject, including special conditions that had been noted in the 1976 TOP. It also prescribed specific conditions that no solid wastes could be placed within 30 feet of any existing or future lake area, no dumping below water at any time nor in any dewatered excavations, and that a quarterly water quality monitoring program at monitoring wells No. 4 through 12 be sampled for specified substances. Proposed Condition 16 stated as follows: Solid waste shall be deposited in locations consistent with those approved in the Army Corps of Engineers' dredge and fill permit #75B-0869. No solid waste shall be deposited in the areas commonly known as the wetlands and transitional zones of said wetlands, as shown on the attached map. Subject to the Corps approval of proposed modifications to permit #75B-0869, a revised DER solid waste permit will be issued consistent with the approved modifications. A sketch of the landfill site purporting to designate the landfill deposal area, wetlands and transitional zone, and mean high water line was attached. (Exhibit 3) The Petitioners consist of the Florida Audubon Society, which has some 2,000 members residing in Dade County, Tropical Audubon Society, which is affiliated with Florida Audubon Society; Keystone Point Homeowners Association, Inc., comprised of approximately 425 owners of mostly waterfront or canal homes in North Miami within a mile of the landfill site; Thomas Pafford, North Miami, Florida, who uses the waters of Biscayne Bay and nearby wetlands for recreational purposes; and Maureen B. Harwitz, who resides within a half mile of the landfill site and uses Biscayne Bay and the mangrove preserve adjacent to the landfill site for recreational purposes. Members of the above-named organizational groups use the waters surrounding the landfill site for recreational purposes and are concerned that the waters and fish and animal life therein will be adversely affected if the operation permit is granted. (Testimony of Lee, Brown, Pafford, Lippelman, Harwitz) Munisport has been operating the North Miami landfill under a lease with the City of North Miami since approximately 1974. The ultimate aim is to convert the area into a recreational complex consisting of golf courses, club house, and other sports facilities. The site was used as an unregulated dump for many years prior to initiation of the Munisport operation. The site has been the subject of previously issued state and Corps of Engineer dredge and fill permits which are not the subject of this proceeding. The landfill site occupies an area generally between Northwest 135th Street on the south and Northwest 151st Street on the north. It lies between Biscayne Boulevard on the west, and state mangrove preserves and land of Florida International University on the east. It is less than a mile to Biscayne Bay on the east side of the landfill. The nearest point of entry is in the southeast area where Arch Creek empties into the Bay. At this time, Munisport has filled approximately 210 acres at the site with ten feet or more of fill material. A final cover has been completed over about 70 acres of this land and a golf course is presently being constructed. Pursuant to the dredge and fill permits, five lakes approximately 35 feet deep are nearly completed and some six or seven more are to be dug in the future pursuant to those permits. These lakes are separated from the solid waste by a 30 foot wide dike of clean fill. Although some cover material has been trucked to the site, about 1.6 million cubic yards of fill from the excavated lakes have been or will be utilized in cover operations for the landfill. The solid waste layer averages 15 feet in depth and lies about two feet above the ground water table. About 230 acres lie within the upland fill area above the mean high water line which is not within the area of jurisdiction of the Army Corps of Engineers. The mean high water line has been established by appropriate procedures under Chapter 177, F.S., and the surveying procedures were approved by the Department of Natural Resources on April 6, 1978. Although not stated in the Notice of Intent to issue the requested permit, DER intends to restrict the life of any permit to the time when the Metropolitan Dade County Resources Recovery Facility commences operation in approximately two years. The applicants and Dade County also have a memorandum of understanding to this effect. (Testimony of Stotts, Checca, Exhibits 1, 2, 35, 36, Hearing Officer's Exhibit 1) Munisport receives solid waste from a variety of firms, institutions, and surrounding municipalities. Its procedures are for vehicles to enter and exit the site from an access road leading to Biscayne Boulevard. A sign is located along the road indicating the operating hours, fee schedule, waste restrictions and other pertinent information. A large portion of the site is virtually inaccessible due to dense mangroves and mosquito control canals and ditches. At the check-in gate, a cursory inspection of vehicle loads is made by Munisport personnel who check the contents for quantity. Each load is directed to a designated place at the site where Munisport employees spread and compact the waste. At this stage, they are instructed to look for any unauthorized materials, such as hazardous and infectious waste. If such wasted is found, the offending party is required to remove it from the site. compactors and bulldozers push the solid waste to the face of the landfill and spread it out to facilitate compaction. During the hours of 6:00 P.M. to 6:00 A.M., a watchman is on duty at the site to accommodate customers. If less than four or five truckloads arrive during the night hours, the material is not processed. If a larger quantity is involved, a Munisport employee moves and covers the material prior to the following workday. Due to the high ground water tabled, the area method is used for filling the site. This is a procedure by which refuse cells are constructed in lifts not to exceed ten feet in vertical height. They are composed of cells which constitute a one-day quantity of refuse. Six inches minimum cover of clean fill is applied daily, and a one foot intermediate cover is applied within a year after compaction. The cells are compacted in two-foot layers and, upon completion of a particular area, a minimum of two feet of final cover is applied. A dike constructed of compacted limerock borders the east side of the site and basically constitutes the present mean high water line. It is designed to protect the adjoining 129 acres of mangrove preserve and Biscayne Bay from any adverse water quality which might occur from runoff of degraded waters from the landfill site in the event of contamination. (Testimony of Haddad, Checca, Exhibit 1, 9) The shallow soil underlying the landfill at depths ranging to almost ten feet consists of a combination of organic matter and debris from prior dump use, muck, and sand. Soil borings taken at the site show that limestone or calcareous rock known as Miami oolite is about eight feet below the soil layer. At this depth is found the Biscayne aquifer that carries the unconfined ground water in the area. The aquifer is approximately 160 feet deep under the site and constitutes the major source of water supply in Dade County. The gradient of the water table for the landfill site runs in a southeasterly direction toward Biscayne Bay. Approximately 75% of the surface soil layer consists of organic muck, whereas in approximately 25% of the area, which was previously filled in the southern and westerly portions before commencement of the Munisport operation, the soil is primarily of a sandy type. (Testimony of Checca, Pitt, Exhibit 1) Leachate is produced in sanitary landfills by precipitation that percolates down through decomposing refuse cells and picks up polluting substances created from the decaying solid waste. It can form a "plume" or "bubble" that takes the course of least resistance in flowing laterally or vertically through a landfill site. The strength and concentration of the leachate is dependent upon various factors including the composition, compaction, and the age of decomposing refuse, and the amount of water being introduced into the area. As it passes slowly through the soil beneath the solid waste material, the unsaturated soils act as filters and permit ion exchange which reduces the quantity of contaminants. Dilution takes place where leachate comes in contact with ground water and leachate movement occurs gradually through the ground water aquifer in its direction of the flow. The presence and movement of leachate normally can be detected by analysis of ground water samples taken at various places throughout the landfill site. (Testimony of Checca, Pitt, Coker, Exhibit 1) Commencing in 1975, a monitoring program was instituted at the sanitary landfill to determine its effects on the ground water regime. A number of monitoring wells at various depths were constructed at different sites at the landfill, and samples were withdrawn and evaluated periodically to determine the types and degrees of pollution being generated by the landfill. Background samples were also obtained from wells off the site to establish the general character of water quality in the area and to compare these samples with those obtained from the site. Additionally, "grab" samples were taken of water from the bay and nearby canals and wetlands. Locations of the background and sampling wells were established by the applicants in conjunction with the DER and the Environmental Protection Agency. To determine the amount of leachate that probably would be generated at the site, the "water balance method" of computing the estimated time required to produce leachate, as well as the quantity that probably would be generated upon completion of the landfill, was made by representatives of the EPA in 1975 utilizing specific climatological and surface conditions at the site. This study indicated that percolation of surface water would increase during the operation of the landfill and before final soil and vegetative cover were in place, and that leachate would occur in about a year in larger quantities than would be produced by a completed landfill. Tests conducted during the ensuing three-year period of both surface and ground water through the monitoring program have failed to produce evidence that water quality is not within acceptable parameters or that water quality in the area surrounding the landfill site has been degraded. No significant differences in the concentrations of various ground water constituents were found between samples obtained at the disposal site and those collected in the adjacent mangrove forest or background areas. Neither was any evidence of contamination from leachate found in samples of surface water collected in the vicinity of the landfill or in nearby natural areas. (Testimony of Checca, Pitt, Linett, Perez, Exhibit 1, Exhibit 33) Three basic factors have undoubtedly accomplished reduction in the amount of leachate generated at the landfill. These are (a) attenuation and filtration of pollutants by unsaturated soils between and beneath the refuse cells, (b) biological assimilation by organisms living within the refuse cells and underlying soils, and (c) dilution upon contact with the ground water. A hydrogeologic study shows that the uppermost 14 feet of the aquifer immediately below the landfill represents only 0.2% of the total discharges with a ground water velocity of less than 0.1 foot per day. This part of the aquifer therefore provides considerable detention time for the water that percolates through the landfill. The strata, as well as the overlying organic marine soils, provide the absorption and assimilation that removes pollutants from the water. After water percolates through this layer, it reaches the highly permeable Miami oolite that carries about 43% of the ground water flow. The effects of soil absorption, filtration through the upper 14 feet of the aquifer, and dilution within the aquifer have demonstrably been sufficient to assimilate the water that percolates through the landfill. It is estimated that the time of travel of ground water from the landfill site to the closest discharge point in Biscayne Bay is approximately 68 years. Although the attenuation capability of the organic muck soil underlying the greater part of the landfill is high, the older area of the site in the southwestern portion which had been filled before the Munisport operation commenced, has no muck and consists primarily of sand with a higher rate of permeability. (Testimony of Checca, Pitt, Teas, Exhibits 1, 33) The fact that the organic muck material under the landfill is not uniform throughout the site, plus the fact that there have been various breaches in the permeable oolite layer below the soil, will, in the opinion of some experts, eventually lead to the generation and movement of a leachate plume into such breaches and ultimately to Biscayne Bay. These breaches consist of the deep lakes at the site, the Arch Creek Canal to the south of the site and a dredged excavation at the exit of that body of water into the bay some 3,600 feet distant from the landfill. Additionally, these experts postulate that the dike located on the eastern border of the site will not prevent leachate from moving into the surrounding mangrove area. It is therefore estimated that in the above ways, large amounts of leachate would enter the bay and adjacent wetlands within a period of five to ten years. (Testimony of Coker, Hudson, Pasley, Browder, Exhibits 12, 14, 29, 30) Although water monitoring at various levels in and at probable discharge points near the site have not found degradation of water quality, the applicants propose to address any future leachate problems in a variety of ways. These include continuous periodic testing of water quality and monitoring wells, excavation of a canal on the upland side of the site to intercept leachate and treatment of any contaminated water therein or by pumping the water to an interior lake for treatment. Based on the particular type of any degradation, chlorination and precipitators would be utilized. Long-range problems will be further reduced by the ultimate construction of the golf courses and placement of final soil and vegetative cover to reduce percolation of surface water. This will be aggravated to an undetermined degree, however, by periodic irrigation of the golf courses. (Testimony of Checca, Pitt, Kelman, Exhibits 1,33) During the early years of the Munisport operation, a number of violations of the conditions of the temporary operating permit occurred, but for the most part these were caused either through simple negligence of landfill personnel, breakdown of equipment, or introduction of unauthorized materials to the site by Munisport customers. In these situations, Munisport usually took prompt and effective action to prevent recurrence and to remedy the problem. For example, on one occasion in 1977, some 12 drums containing residue of a chemical substance deemed to constitute "hazardous waste" was brought into the site by persons unknown and was found leaking into the ground. A number of violations and warning notices were issued to Munisport by the Dade County Department of Environmental Resources Management (DERM), primarily in 1976, involving the placement of tree cuttings and wood scraps into excavations containing water at the south end of the site. These occurred, however, during a period when Munisport was engaging in tests to determine the suitability of such operations in conjunction with DER. Additionally, in 1976 and 1977, Munisport was advised of violations in the placement of garbage in exposed water, uncovered garbage, and delivery of garbage after hours. Munisport has had a continuing problem over the years with the unauthorized delivery of hospital wastes from various customers to the landfill in spite of letters written to hospital facilities and delivery firms cautioning them concerning the prohibition against the introduction of such material to the landfill. DERM personnel concede, however, that the operation has been continuously improved and that it is well-conducted in comparison with other landfills in the country. However, they believe that lakes should not exist in landfills and that the North Miami landfill is too close to the wetlands. (Testimony of Morrissey, Karafel, Sobrino, Haddad, Checca, Exhibits 6-11, 17, 18, 20-24, 27, supplemented by testimony of Pafford and Exhibit 16) In a letter of January 17, 1977, DERM expressed concerns about the Munisport operation to DER. One of these concerns was that leachate would migrate to proposed golf course lakes and the resulting pollution would produce poor water quality. Although 1976 testing of then existing lakes at the site reflected unusually high amounts of fecal coliform, subsequent tests in late 1978 showed very little, but tests again in January, 1979, showed that several lakes were again somewhat high in coliform. Coliform is not considered to be a strong parameter in assessing the presence of leachate and amounts vary considerably from day to day in lake areas. Additionally, great numbers of birds are normally present on the landfill site during operations and contribute in raising coliform readings to some extent. Dade County has a current policy that does not permit lakes to be excavated on landfills operated by the county. (Testimony of Checca, Morrissey, Sobrino, Karafel, Kosakowski, Linett, Newman, Kelman, Perez, Exhibits 17, 19, 20, 24, 25, 31, 32, 37, 38)
Recommendation That a permit be issued to the City of North Miami, Florida and Munisport, Inc. to operate the solid waste disposal facility as described and under the conditions stated in the letter of the Department of Environmental Regulation, dated January 27, 1978, wherein it gave notice of its intent to issue the said permit.
