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 the installation of an OSDS on property which he owns near the Suwannee River in Dixie County, Florida, in accordance with the provisions of Section 381.272, Florida Statutes, and Chapter 10D-6, Florida Administrative Code.
Findings Of Fact The Petitioner is the owner of certain real property located in Dixie County, Florida, more particularly described as part of Section 30, Township 10 South, Range 14 East. The property is approximately 8.5 acres in size. The Petitioner purchased the property some ten-years ago, and the lot in question has never been platted. The petitioner purchased the property for purposes of constructing a residence for himself and his family. At the time that the Petitioner purchased the property, and since, there have been occupied homes on either side of the property served by septic tank and drain-field sewage disposal systems. There came a time when the Petitioner elected to construct a home on his property and applied to the Respondent for an OSDS permit on January 19, 1990. On April 20, 1990, after having its personnel make on-site inspections of the property, the Respondent determined that the propert, according to Suwannee River Water Management District calculations, lay beneath the ten-year flood elevation. The Respondent, therefore, denied the permit application. Pursuant to information obtained from a registered land surveyor, the benchmark elevation of the surface of the Petitioner's property is 14.56 feet above mean sea level ("MSL") The actual surface elevation is 6 inches lower than that or approximately 14 feet. The ten-year flood elevation level for the Petitioner's property, at the Suwannee River mile involved, is 17 feet above MSL. Thus, the surface of the Petitioner's property is some three feet beneath the ten-year flood elevation and were a drain-field system installed on the property, the bottom of the drain-field trench or absorption bed would be a greater distance beneath the ten-year flood elevation. A "mounded" septic tank and drain-field system might be feasible for the subject property because of the property's adequate size, although such a mounding might have to be approximately five feet or greater in height over the present grade level of the property. The Petitioner, however, did not adduce any testimony or evidence concerning the feasibility of such a mounded disposal system, including details of how it would be constructed and operated and whether there is adequate room on his property to build such a mounded system, including the required undisturbed land area around such a system. The Petitioner did not adduce testimony or evidence in support of the feasibility of any other alternative sewage treatment and disposal system for the subject property. In fact, the property is located within the regulatory floodway of the Suwannee River. Because of this, the rule cited hereinbelow would require that a registered engineer certify and adequately explain the manner and method by which such a mounded system could be built on this property within the regulatory floodway, without altering the level of the "base flood", as, for instance, by excavating an equal volume of fill from another location within the regulatory floodway. However, such engineering testimony and evidence was not offered by the Petitioner; therefore, it has not been established that such a mounded system is a feasible alternative nor has it been established that any other type of treatment and disposal system is a feasible alternative because of the dearth of such evidence. The Petitioner did not apply for a variance. In any event, however, although the Petitioner clearly has been placed at a hardship because of not being able to construct the retirement residence he has desired for years on the subject property, because of the inability, thus fail at least, to obtain an OSDS permit, the Petitioner has not established- with regard to the below- referenced variance criteria that no reasonable alternative exists to the installation of the subject proposed system beneath the present surface of the lot which would be beneath the ten-year flood elevation. The Petitioner has not offered evidence to establish that the installation of the proposed system will not adversely affect public health and will not degrade the surface and ground waters involved in the immediate area. Thus, the standards for the grant of a variance have not been established by the Petitioner's proof, although it is understood that the Petitioner did not leek a variance, at least as yet. In that connection, the Respondent asserts that the Petitioner was not accorded the opportunity to avail himself of the Department's 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's within the ten-year flood elevation. The Governor's Executive Order, which incorporated the "Suwannee River Task Force" recommendation to preclude such systems 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. The Petitioner's proof and, indeed, Respondent's Exhibit NO. 2 establishes that this property is relatively high in elevation, is well-drained, and not subject to frequent flooding, although it does lie beneath the ten-year flood elevation. The soil profile indicates that fine sand exists from the surface down to 72 inches. This type of soil promotes very good percolation of water and, thus, would result in adequate operation of a septic tank and drain field if all other appropriate standards and conditions necessary for such adequate operation were met. In fact, the wet season water table is some 36 inches beneath the surface; and, in general, this property has been shown to be well-suited to the installation of a septic tank and drain-field system, but for the ten-year flood elevation circumstance delineated above.
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 applying and 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.

Findings Of Fact The property upon which Petitioner seeks a variance from the normal requirements for attaining a permit to install an on-site sewage disposal system is found in Leon County, Florida. Specifically, it is located at Lot 4, Block A, Killearn Lakes Unit I. The relative position of this lot in the subdivision is depicted within Petitioner's Exhibit 1 and Respondent's Exhibit 2 admitted into evidence. Respondent's Exhibits 3 through 5 are photographs of the site. Petitioner intends to construct a 1,200 square foot residence. As the photographs depict, some preparation has commenced to the extent of lot clearing and other site work where the home would be constructed. Killearn Lakes Unit I is a pre-1972 subdivision. When the development commenced, it was anticipated that a community sewer system would be utilized, as contemplated by the plans submitted in April, 1971. Subsequently, some lots within the Killearn Lakes Unit I were allowed to be developed with the use of on-site sewage disposal systems, namely septic tanks. There are 150 lots in that category. In 1979, with the advent of certain rules under Chapter 10D-6, Florida Administrative Code, the development was allowed to proceed on the basis of four septic tanks per acre. Over time, Killearn Lakes Unit I experienced a history of failures with on-site sewage disposal systems. The failures were promoted by problems with the "sheet flow" drainage system and its patterns of dispersion of storm water runoff, problems of soil permeability and abnormally high wet season water tables, referred to as perched water tables. This resulted in sewage backing up into homes and flowing out onto the ground in the yards of the residences, into streets and onto adjacent neighbors' lots. The problems experienced were widespread within the Killearn Lakes Unit I. This seepage of raw sewage presented a health hazard, as it would on any occasion. Among the residences confronted with this dilemma was Lot 5, Block X, adjacent to the subject lot. Persons residing in that home had to undertake alternative means of on-site sewage disposal to have that system function properly. This included relocation of the apparatus, mounding, use of an aerobic system, and use of pumps to insure that the waste being disposed did not back up into the conveniences within the home. Witnesses who appeared at the hearing described the series of corrections in some detail. Those witnesses included a former owner of that residence and others who had a technical understanding of the problems in that system. The problems in Killearn Lakes Unit I related to on-site sewage disposal systems became so extreme that the Leon County Commission declared a moratorium on the installation of on-site septic tanks in that development. This occurred in 1987. In order to better understand the problems in the Killearn Lakes subdivision, to include Killearn Lakes Unit I, a study was commissioned. That report is referred to as Killearn Lake Waste Water Disposal Study of June, 1987. A copy of the report is found as Respondent's Exhibit 6 admitted into evidence. It was prepared for the Leon County Board of County Commissioners and prepared by the Leon County Public Health Unit with the assistance of the Leon County Department of Public Works, Leon County Building Department, Ochlockonee River Soil and Water Conservation District, Northwest Florida Water Management District, Tallahassee-Leon County Planning Department, Florida Department of Health and Rehabilitative Services, and Florida Department of Environmental Regulation. Some of the highlights of that report concerned the observation that the septic tank systems do not work adequately and that the more systems that are placed the greater the problems. It noted that the nature of the drainage system in this area is a contributing factor to the failures. The soil's poor permeability, relating to the Dothan series of soils in the area which have slow permeability, contributed to the problem. Perched water tables were found above the expected levels for the wet season water tables. They also presented a problem, as did excessive slopes in some areas. In particular, it was noted that 80% of the lots sampled in Killearn Lakes Unit I had severe limitations on the use of on-site sewage disposal systems. Ninety-three per cent of the lots sampled in Block X received excess runoff from other lots and roads at higher elevations. It was noted that French or curtain drains alone would not significantly reduce perched water table complications because of the low permeability of the soils. It was reported that the overall housing density of Killearn Lakes is not particularly high, but the individual lots are small, approximately 1/4 acre in size. This, taken together with the fact that the "sheet flow" concept of storm water management contemplates that the runoff will cascade across the terrain conforming to its contours, means that some small lots will be inundated. This uncontrolled runoff contributes to septic tank problems in that the tanks fail when the soils around them become saturated. The report notes that if there was a different designed drainage system, the impact on septic tanks would be less. The report notes that if something is not done to modify storm water runoff, drainage problems will persist. Consequently, septic tank failures will continue to occur. Concerning the water tables, the soil testing, which was done in Killearn Lakes Unit I, in which the predominant soil is Dothan type, demonstrated that the borings which located mottling of the soils at the expected level of the wet season water table were inaccurate. These indicators did not correspond to reality in that the true water tables were found 12-20 inches above the expected level of the average high water, as seen in the mottling. This phenomenon was revealed in 42% of the lots evaluated which had Dothan soils. The report recommended, among other measures, that no new sewage disposal system permits be issued in Killearn Lakes Unit I until a storm water system had been constructed and demonstration made that the system would collect storm water and thereby lower the perched water table on specific lots under review. The ultimate response to the question of permits for on-site sewage disposal systems in Killearn Lakes Unit I was spoken to in a Resolution of July 14, 1987 entered by the Leon County Board of County Commissioners. A copy of the resolution may be found as Respondent's Exhibit 1 admitted into evidence. It was resolved that the permits for on-site septic disposal systems be reviewed by the Leon County Public Health Unit on a case-by-case basis in accordance with criteria announced at Chapter 10D-6, Florida Administrative Code. This effectively lifted the moratorium. The subject request for installation of an on-site sewage disposal system was reviewed in keeping with the policy decision set forth in the resolution. Respondent's Exhibit 6 admitted into evidence includes a copy of a survey made by the Homeowners' Association for Killearn Lakes, also admitted as Petitioner's Exhibit 1. As part of the study commissioned by the Leon County Board of County Commissioners, it has some relevance in portraying the dimensions of the problem. Those dimensions are better understood by resort to the color scheme which is found in Petitioner's Exhibit 1. It depicts the problem lots in red color, those lots without problems in green color, and the lots upon which no report was made in orange color, as well as vacant lots, to include the subject lot, which have no color scheme. This latter category indicates no participation in the survey. The door-to-door personal survey conducted by Rod Moeller and testified about at hearing does not diminish the impression of the seriousness of the problem with on-site sewage disposal system failures in Killearn Lakes Unit I, which the 1987 study by the Leon County Board of County Commissioners identified. This survey by Mr. Moeller was in a limited area, more specifically related to the portion of Killearn Lakes Unit I nearby the subject lot. The findings of the 1987 study commissioned by the Leon County Board of County Commissioners are accepted as accurate. Eanix Poole, Administrator of Environmental Health for the State Health Office testified at the hearing. He pointed out that the failure rate in the subdivision under question for on-site sewage disposal systems is 25%, as contrasted with the statewide rate of less than 1/2%. He identified the fact that those failures relate to backups within the home and seepage onto the ground. He verified that these events constitute health problems, especially given the number of failures. He sees the lot in question here as being particularly vulnerable to problems given the drainage patterns and its location at the bottom of two hills. The lot in question receives runoff from the two adjacent lots as well. Mr. Poole sees the subject lot as more vulnerable in the wet season and does not believe that any alternatives that are available for placement of the system on the site would sufficiently alleviate the potential failure of the system to make it a successful arrangement. What he sees is a lot in the path of a natural drainage of tremendous quantities of storm water runoff, coupled with poor soil conditions related to soil absorption or permeability in an area where on-site sewage disposal systems have failed. He remarks that dry soils are needed to treat the sewage and that treatment cannot take place in a saturated soil environment. The effects of seepage of the sewage, according to Mr. Poole, is one which can degrade ground water. Mr. Poole is also concerned that the installation of the proposed on-site sewage disposal system above ground will have an adverse impact on the adjacent lots, one of which has already experienced problems. That refers to Lot 5, Block X. These observations by Mr. Poole, as reported, are accepted. Raymond Collins, an environmental administrator with the Respondent's health program office, also testified at the hearing. He is intimately aware of the problems in Killearn Lakes Unit I. Those problems began to occur in the winter of 1986 and continued into 1987. This related to problems with toilets and the seepage of effluent which was running onto people's property and into the streets. He notes a similar failure rate in Killearn Lakes Unit I to that observed by Mr. Peel when contrasted with the experience statewide. In the aforementioned period he received calls and reports from homeowners concerning system failures. In effect what was happening was that the on-site drain fields in Killearn Lakes Unit I would not accept more input and the raw sewage would bubble up and leach out onto the ground. He personally observed a dozen sites which had failures. He was responsible for the coordination of the July, 1987 study which has been mentioned. As a result of that study one of the steps which he took was to advise that staff investigating the permit application requests should elevate the estimation of the wet season water table by 12-20 inches. Mr. Collins agrees with the recommendation of the individual who was assigned to evaluate the application for permission to install an on-site sewage disposal system at the subject lot, who recommended that the application be turned down. Mr. Collins' description of the experience at Lot 5, Block X, related to his knowledge that the initial system had been replaced with an aerobic system, which also proved to be an inadequate on-site sewage disposal system. In 1988, he went to the home of the person living on that lot, and the aerobic system was not working. There was a light rain on that day, and there were problems in the drain-field area. When a soil boring was made to a depth of two feet effluent poured out. The perched water table had risen to a point in the bottom of the drain field, such that when a hole was punched, it provided a conduit for pressure to be relieved. The drain field that was experiencing this problem was not the original drain field. It was a replacement drain field. The drain field being observed was in the front of the lot, right below the ground. The suggestion to alleviate the problem was to move the drain field to the side of the yard and elevate it and install a series of small-diameter pipes. A pump was also needed to move effluent into the drain field, thus, avoiding a backup of the system into the home. He is unaware of any recent failures in the system at Lot 5, Block X. Mr. Collins emphasized the need for soil to remain unsaturated to provide effective treatment and that 24 inches of unsaturated soil is the minimum amount which would be acceptable. Mr. Collins commented about the nature of the subject lot and the fact that other lots drain through it. Mr. Collins commented that the design of the proposed septic tank does not assure success in the treatment of the waste disposed. Unlike the expert of the Petitioner, Mr. Peel, the problem is not that solids are blocking up the system. It is the failure of the soils to accept the volume of water which is being released from the chambers of the septic tank into the drain field. Mr. Collins does not believe that the use of water-saving appliances in addition to the limited size of the home to be built on the subject lot, installation of an aerobic system, and installation of an above-ground system, as proposed, would be successful and not pose a health risk from system failure. The problems would continue to be drainage patterns and poor soils. His remarks, as reported, are accepted as accurate. Terese A. Hegg, Environmental Specialist I with the Respondent's Leon County Public Health Unit, reviewed the application for variance to install the on-site sewage disposal system. She was familiar with the history of problems in Killearn Lakes Unit I before undertaking this assignment and has made more than 50 evaluations in that development. She observed that the "sheet flow" drainage of storm water does not provide reasonable management because it does not drain normally. She is aware that the wet season water table is as much as 20 inches above the normal indicators, as seen through mottling. Her analysis of this site is under the auspices of those requirements announced in Chapter 10D-6.044, Florida Administrative Code, having in mind that the subdivision plat was made before 1972. This includes an examination of the soil characteristics, history of flooding, and water table evaluations. At this site, she noted the poor permeability of the soil. She did soil borings to confirm the nature of the soils and to identify the water table. She took into account the abnormal perched water table that is above what the mottling would indicate as being the wet season water table. Ms. Hegg is concerned that the system on the adjacent lot, which is now functioning adequately, would not function adequately if the subject system was installed. She noted that the drainage pattern from the neighboring lots was toward the subject lot and that water would come from the left and the right lots adjacent to this lot, corresponding to Lots 5 and 3 as you face them. The drainage pattern would then proceed beyond Lot 4 and into a green area. In making her assessment of this application, she was aware of the problems with the on-site sewage disposal system at Lot 5, Block X. The appearance of saturated soil in the entire length of the boring and standing water on the lot is an indication of problems with percolation. The effluent will flow out and onto the ground if these soils are saturated. From her observations and based upon the history of Killearn Lakes Unit I and its failures regarding on-site sewage disposal systems, Ms. Hegg does not believe that the proposed system would successfully address sewage treatment and would promote a risk of on-site sewage disposal system failures for adjacent lots. Ms. Hegg acknowledged that the storm water flows could be diverted; however, she points out that the subsurface water cannot be diverted. Her account of this site and the acceptability of the request for variance as reported is accepted as accurate. Given the soil conditions and the wet season water table expected at this site, the proposed system will not present an adequate unsaturated soil depth for treatment of the sewage and untreated sewage may be expected to seep or leach out onto the ground. On May 22, 1990, Mr. Collins had written to Dr. Richard G. Hunter, Assistant Health Officer for Environmental Health, recommending the denial of the variance request. A copy of that correspondence may be found as Respondent's Exhibit 7 admitted into evidence. It details reasons which are similar to those described in this Recommended Order. As a consequence, even though the Advisory Review Variance Board had looked with favor upon the request for variance, that variance was denied by action of Dr. Hunter on May 30, 1990, which relied upon the insights of Mr. Collins, as described in his May 22, 1990 correspondence. A copy of the letter of denial may be found as Respondent's Exhibit 8 admitted into evidence. The purpose of this hearing was not to examine whether Respondent had abused its discretion in denying the variance. The reason for the hearing was to allow the parties to present their points in an adversarial setting, which allowed each party to explain its viewpoint anew. That was done, and the analysis provided by this recommended order ensued. In deciding the facts, these representations have been made with due regard to the remarks of James Earl Peel, an expert in the design of on-site sewage disposal systems, who had on his staff, Gary L. Wood, P.E. His methods in analyzing the issue of the suitability of the installation of an on-site sewage disposal system at the subject site do not coincide with the methods contemplated in Chapter 10D-6, Florida Administrative Code, which controls. This is especially significant in his approaches to soil characteristics and location of the wet season water table. As noted above, his belief that the problem is one of distribution of solids from the septic tank into the drain field overlooks the more significant problem of water volume discharge from the septic tank into the drain field. In fact, Mr. Peel indicated that he is unfamiliar with the requirements of septic tank design, as described in Chapter 10D-6, Florida Administrative Code. On balance, Mr. Peel's reports, in Petitioner's Exhibits 3 and 4 admitted into evidence and his in-hearing testimony, do not persuade that the system he recommends can be successfully operated at the subject site. His presentation and the overall presentation of Petitioner do not create a reasonable expectation that the system will not fail and create health hazards for the residents of Lot 4, Block X, and others in the vicinity. It is recognized that this lot owner faces a hardship that was not caused by Petitioner. It is also recognized that, pursuant to the stipulation of the parties, there is no intention by any entity to install a community system of sewage disposal. It is further recognized that there are no alternative methods that would seem to be successful in addressing the problem of the treatment of the sewage, as related in the previous findings. On the other hand, the discharge that could be expected from this subject system would bring about a condition in which the effluent presented a health risk to this applicant and other members of the public and has the potential to significantly degrade the ground or surface waters, although this latter circumstance has not been documented on other occasions and was not found to exist in the July, 1987 study commissioned by the Leon County Board of County Commissioners. In that report, it was specifically found that the surface water had not been compromised by the on-site sewage disposal system failures described in the overall report.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that a Final Order be entered denying Petitioner's request for variance from permit requirements and permission to install an on-site sewage disposal system at Lot 4, Block X, Killearn Lakes Unit I. DONE AND ENTERED this 20th day of November, 1990, in Tallahassee, Leon County, Florida. CHARLES C. ADAMS, Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, FL 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 20th day of November, 1990. APPENDIX TO RECOMMENDED ORDER IN CASE NO. 90-4456 The following discussion is given concerning the proposed facts of the parties: In the discussion of the testimony of Mr. Poole, the relevant portions of that testimony are reflected in the facts found in this recommended order. Under the heading of testimony said to be attributable to Ms. Hegg, at paragraph 1, while it is recognized that a system might be installed that might not call for diversion of storm water onto adjacent neighbors' properties, the problem on site would remain and would be sufficient reason to reject the application. Moreover, it is not clear that it is the intention to install a system that would divert storm water from adjacent properties. Paragraph 2 under this heading is rejected in its notion that storm water would not have an influence on the proposed system. Paragraph 3 is rejected. Paragraphs 4 and 5 do not lead to the conclusion that sufficient unsaturated soils would be available for the treatment of disposed sewage during the wet season, nor does the representation at paragraph 6. Paragraph 7 under that heading is contrary to facts found. The paragraphs under the reference to James Earl Peel, in those five paragraphs, while accurately portraying the opinion of Mr. Peel and Mr. Wood, does not lead to the conclusion that the application should be granted. Under the heading "Rod Moeller" in the first paragraph, the information provided at hearing and under weather reports does not satisfactorily establish what the rainfall circumstance may have been at the subject property 72 hours before January 24, 1990, as referred to in paragraph 1, nor can it be said that the rain experienced in the overall area contemplated by the attached weather report to the argument by Petitioner was a 25-year storm event. The comment at paragraph 3 under this category that the on-site sewage disposal systems in neighboring lots are functioning fine since modifications in the advent of hurricane "Kate" is contrary to facts found. Under the heading "Ray Collins" in paragraph 1, this proposed fact has no relevance in that the question is the appropriate function within Killearn Lakes Unit I, not at an undisclosed site away from that area. Respondent's Facts These facts are subordinate to facts found.

The Issue Whether Respondents' Division of Hotel and Restaurants' license should be suspended or revoked, or a civil penalty assessed for alleged violation of Division Rule 7C-4.01(5)(c) and Florida Statute s. 509.221, as set forth in Notice to Show Cause issued by the Petitioner.
Findings Of Fact On April 19, 1977, Johnny Bell, inspector for petitioner's Division of Hotels and Restaurants, received notification from the Health Department of Sarasota County that respondents' place of business, Port-of-Call, resort apartments located at Longboat Key, Florida, was not connected to the sewerage system of Longboat Key. Bell inspected respondents' premises and discovered that a septic tank system was in use at the Port-of-Call. He informed respondents that they must connect to an "approved" sewerage system within sixty (60) days. On June 20, 1977, Bell returned to the premises and found that no action had been taken to connect to the Longboat Key system. Respondent Edward W. Henderson informed him that he should not have to go on such a system because his septic tanks were adequate and functioning properly. Bell did not examine the septic tanks or ascertain if they were, in fact, in proper condition and operating satisfactorily. He proceeded to issue a Notice to Show Cause as to why respondents' license No. 68-606H should not have a civil penalty assessed against it or be suspended or revoked. The stated cause for such intended action was as follows: "Division Rule 7C-4.01(5)(c) ; Florida Statutes 509.221 -- Failure to have sewage system hooked into public sewerage system." The Notice to Show Cause also informed respondents of their right to an Administrative Hearing under Chapter 120, Florida Statutes. Respondents thereafter requested such a hearing. There is no food operation at the Port-of- Call. (Testimony of Bell, Exhibit 1)

The Issue The issue is whether Petitioner's request for a variance from agency rules governing daily domestic sewage flow so as to authorize an increase in the number of seats for his restaurant located in Howey in the Hills, Florida, should be approved.
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: Petitioner, Fletcher C. Bishop, Jr., is the owner of a parcel of property located at Lot 22, Block C-2, Lakeshore Heights Subdivision, 102 South Palm Avenue, Howey in the Hills, Florida. The property consists of .0946 acre, or approximately one-tenth of an acre, and is one of several parcels located in Block C-2. Since January 1997, the property has been leased to Robert P. Jencic, who now operates a pizza restaurant on the premises known as Hungry Howies Pizza Shop. According to Jencic, he has a contract to purchase the property from Bishop at the end of his lease, or on March 1, 1998. Whether the property was actually purchased by Jencic on that date is not of record. Lakeshore Heights Subdivision is not served by a central wastewater treatment system; rather, each lot is served by a septic tank and drainfield system. Lot 22 adjoins several other commercial or business establishments situated on Lots 20, 21, 23, and 23A in the western half of Block C-2, and all share a common drainfield easement located to the rear of the lots. Except for Lot 20, all lots have tied into the drainfield and now use the easement for waste disposal purposes. Because they share a common easement, each lot has been allocated a portion of the easement for its respective septic tank and drainfield. In Petitioner's case, he has been allocated approximately 990 square feet. After Jencic signed a commitment in January 1997 to lease and purchase the property, he made extensive renovations in order to convert the property to a restaurant. On or about February 20, 1997, Jencic met with a representative of the Lake County Health Department, an agency under the direction and control of Respondent, Department of Health (Department). At that time, Jencic filed an application for a site evaluation concerning the replacement of the existing onsite sewage disposal system. The application noted that he intended to operate a pizza restaurant with 56 proposed seats. On February 21, 1997, a site evaluation was conducted by Robin Gutting, a Lake County Department of Health environmental supervisor. According to her report [t]he property size of 4120 square feet with available central water will allow a maximum 236 gallons of sewage flow per day . . . This will allow a 12 seat restaurant using single service articles and operating less than 16 hours per day. . . The size of the Onsite Sewage Treatment and Disposal System would be a minimum 900 gallon tank with 197 square feet of drainfield trench configuration. (emphasis added) Jancic received a copy of the report on or about March 12, 1997, and it clearly conveyed to him the fact that he could operate no more than 12 seats in his restaurant due to sewage flow limitations on his property. Despite being on notice that the restaurant would be limited to only 12 seats due to the lot flow restrictions, on March 19, 1997, Jencic filed an application with the Lake County Health Department for a construction permit to replace the existing septic tank with a 900 gallon septic tank, install a 900 gallon grease trap, and utilize a 197 square-foot primary drainfield and a 200 square-foot bed system. The application indicated that Jencic intended to operate a restaurant "for 12 seats, single service, open less than 16 hours per day." On May 28, 1997, Jencic's application was approved for "12 seats, single service, open less than 16 hours per day." After installing the new tank and grease trap, Jencic began restaurant operations subject to the above restrictions. After operating his pizza restaurant for a short period of time, Jencic determined that he could generate a profit only if the restaurant could be expanded to allow more seats, and he could use china and silverware (full service articles) rather than single service articles (throwaway utensils). To do this, however, he would need a larger sewage treatment system. By letter dated November 9, 1997, Jencic requested a variance from various Department standards for onsite sewage treatment and disposal systems so as to "increase the seating from 12 seats to a maximum of 36 seats and [authorize] the use of china, silverware, and dishes." Although the letter does not refer to any rules, the Department has treated the letter as seeking a variance from three of its rules found in Part I, Chapter 64E-6, Florida Administrative Code. First, Rule 64E-6.001(4)(c), Florida Administrative Code, provides that an establishment cannot exceed the lot flow allowances authorized under Rule 64E-6.005(7)(c), Florida Administrative Code. If the seating capacity in the restaurant were increased, Jencic would exceed the lot flow allowances in violation of this rule. Second, Rule 64E-6.005(7)(b), Florida Administrative Code, prescribes the manner in which a determination of lot densities shall be made. Among other things, daily sewage flow cannot exceed an average of 2,500 gallons per day per acre. The easement which Petitioner shares with other lots is far less than an acre, even counting the space allocated to the adjoining lots. Finally, Rule 64E-6.008(1), Florida Administrative Code, provides that minimum design flows for systems serving a structure shall be based on the estimated daily sewage flow as determined by Table I of the rule. That table specifies an estimated daily sewage flow of 20 gallons per seat for restaurants using single service articles only and operating less than 16 hours per day. Therefore, a 12-seat restaurant with those operating characteristics would require a system that could handle at least 240 gallons of sewage flow per day. The table further provides that a restaurant operating 16 hours or less per day with full service will generate an estimated sewage flow of 40 gallons per seat. Thus, a restaurant with up to 36 seats, as Jencic has requested, would require a system handling at least 1,440 gallons of sewage flow per day. In order to qualify for a variance, an applicant must show that (a) the hardship was not caused intentionally by the action of the applicant; (b) no reasonable alternative exists for the treatment of the sewage; and (c) the discharge from the onsite sewage treatment and disposal system will not adversely affect the health of the applicant or significantly degrade the groundwater or surface waters. In its letter denying the variance, the Department asserts that Jancic has failed to show that items (a) and (c) have been satisfied. Jencic, who recently immigrated to this country, will suffer considerable financial hardship if the request for a variance is denied. Indeed, he demonstrated at hearing that his life savings have been invested in the restaurant, and his parents have placed a substantial mortgage on their property to assist him in his endeavor. If he does not purchase the property as required by his contract, he will be forced to restore the property to its original condition at great expense. In short, given his investment in renovations and equipment, unless the restaurant is expanded, he fears he must file for bankruptcy. Both parties agree that Jancic will suffer a hardship if the variance is not approved. However, Jancic was aware of the lot flow limitations before he made application to replace the existing septic tank in March 1997, and well before he began operating the restaurant in May 1997. Unfortunately, then, it must be found that the hardship was intentionally created by Jencic's own actions. If the variance were approved, it would result in a much larger amount of sewage being discharged into the easement, which could not handle that amount of flow. This in turn could cause the system to fail, thus creating a sanitary nuisance and the leaching of sewage into the groundwater. In this respect, Jancic has failed to show that the discharge will not adversely affect the health of the applicant or significantly degrade the groundwater or surface waters. Jencic offered into evidence a summary of his water usage during a representative period in 1997. That document indicated that metered water usage was approximately 3,000 to 4,000 gallons per month, even when he temporarily (and without authority) expanded his restaurant to 24 seats during a recent two-month period to test water consumption at the higher seating capacity. However, because the sewage strength of a restaurant is far greater than that of a residence, a sewage system must be sized on estimated waste flow, and not metered water flow rates. Therefore, the fact that Jancic's monthly metered water usage is less than 4,000 gallons is not relevant to a determination of the issues. The same finding must be made with respect to Jancic's well-intentioned efforts to decrease water flow by installing high pressure toilets and timed spring systems on his hand sinks. Jencic also requested that he be allowed "spike time" during the hours of 11:30 a.m. to 1:00 p.m. and 6:00 p.m. to 7:30 p.m., which are his peak hours of the day. In other words, the undersigned assumes that he is asking that consideration be given to the fact that he has virtually no business during the other hours of the working day, and that the flow during the peak hours alone would not be excessive on a daily basis. However, the Department's rules are calculated to maximum usage, and thus a "spike" allowance is not allowed.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Department of Health enter a Final Order denying Petitioner's request for a variance.

The Issue The issues are: (1.) Whether Respondents' request for variance from requirements of Rule Chapter 10D-6, Florida Administrative Code, should be granted. (2.) Whether Respondents are guilty of violation of certain provisions of Chapter 381 and Chapter 403, Florida Statutes, and Rule Chapter 10D-6, Rule Chapter 17-550, and Rule Chapter 17-555, Florida Administrative Code, regulating the operation of onsite sewage disposal systems.
Findings Of Fact Respondent V.M.P. Corporation (VMP) operates a lounge known as Stud's Pub in Jacksonville, Florida. Licensed for 75 seats, the lounge actually contains 50-55 seats and employs five people full time. Additionally, 10-15 independent entrepreneurs known as dancers may be present at times. The dancers are not employees of Respondents. Less than 25 people, other than patrons, are present at the facility at any time. Respondent Vincent M. Paul (Paul) owns the facility and the corporation. The lounge is on lots that were platted prior to 1972. Petitioner is the statutory entity with authority for granting variances for onsite sewage disposal systems regulated by Petitioner pursuant to provisions of Section 381.0065(8)(a), Florida Statutes (1991). The lounge is serviced by a septic tank with a drainfield which is covered by an asphalt parking lot. The portion of the parking lot over the drainfield is bounded to the west by a dirt city street, to the north by other pervious surfaces, to the east by the lounge and to the south by the remainder of the asphalt parking lot. A sign on the premises which advertises the business is protected from automobile traffic by concrete barriers. The septic tank system and drainfield were installed prior to 1972 by a previous owner. Respondent Paul retrofitted the septic tank system after 1972. Respondent Paul was responsible for paving over the drainfield after he purchased the property. Petitioner's representatives inspected the lounge, determined the drainfield to be covered by the asphalt parking lot and requested Respondents to remove the asphalt covering. Respondents requested a variance pursuant to Rule 10D Administrative Code, for the asphalt covered drainfield and other deficiencies of the onsite sewage disposal system. Petitioner's review board recommended denial of the request on the basis that the variance would not constitute a "minor deviation" from rule requirements. Although the term is not defined by Petitioner's rule, Petitioner's usage of this term was the result of the consideration by Petitioner's review board of the application for variance within the context of Section 385.0065(8)(a), Florida Statutes, which authorizes Petitioner to grant variances only where the hardship is not intentionally caused by the applicant, where no reasonable alternatives exist and where no evidence of adverse effect upon public health or ground and surface waters is demonstrated. Respondent has no record of failure of the septic tank or drainfield. Water samples from the onsite potable water well filed with Petitioner tested below detectable limits for nitrates and coliforms, the only parameters Petitioner is required to analyze. Respondents' records of water flow or usage from the well into the lounge show daily flow rates of between 320 and 580 gallons, with an average rate of between 450 and 480 gallons. Respondent Paul is responsible for the installation of an unpermitted chlorinator on the water supply system which provided actual flow information. The only onsite water well has no grout sealant. It is the only well of which the parties are aware that lies within 100 feet of the septic system. The potable water well is located approximately 42 feet from the edge of the covered drainfield. The well head does not extend above line surface and there is no concrete pad around the wellhead. The exact depth of the well is unknown, although the well is located upgradient of the drainfield and a nearby junkyard. Denial of the variance would require that Respondents uncover the drainfield since there is no practically available offsite sewage system currently available. Soil in the area of the drainfield is classified as well- draining sand. Due to the impervious surface covering the drainfield, Petitioner's representative was unable, during his inspection, to discern any symptoms of drainfield failure in the form of "blow field should be totally unobstructed to allow aerobic processes to take place in the drainfield which will permit the breakdown of contaminants. A portion of Respondents' 1200 gallon septic tank is located partially under and immediately adjacent to Respondents' facility. A dousing tank which retains liquid waste and operates as part of the septic system is also totally covered by the asphalt pavement. Although there has been no detectable failure of the system, every eight or nine months Respondents have the septic tank and dousing tank pumped out. The tanks never get full.
Recommendation Based on the foregoing, it is hereby Recommended that a final order be entered by Petitioner denying the variance requested by Respondent with exception of such minimal distance as may be required to relocate the water well as far as possible from the drainfield on the Respondent property, and, Further Recommended that such final order also assess Respondent Paul an administrative penalty of $500 for each of the four violations contained in the Administrative Complaint which were proven in this proceeding for a total of $2000, and a continuing assessment of $500 per day for each violation for a total of up to $2000 per day after first allowing Respondents a 60 day period within which to correct all four violations.

The Issue Whether the Petitioner's request for variance should be granted.
Findings Of Fact Petitioner owns a parcel of land in Palm Beach, County on which is housed Petitioner's paving and landscapping business and which is zoned for industrial use. Petitioner intends to install a manufactured building for use as an office. To provide sewage treatment for the bathroom of the office, Petitioner had a septic tank designed and applied for a septic tank permit which was denied as was its variance request. As a result of a complaint, Petitioner was inspected in August, 1988, by the Palm Beach County Department of Environmental Resources Management and by the Florida Department of Environmental Regulation. Both inspections yielded citiations for soil contamination by oil and other hazardous waste. Petitioner represented that most of the infractions had been rectified by the date of the hearing in this matter and pledged full cooperation with the County and State rules. To oversee the operation of the business and assure that no further problems arose, Petitioner decided to establish its office on site. The closest sewage treatment plant is at full capacity and does not intend to provide service to the parcel in the near future. The adjoining properties are serviced by septic tanks. As such, the proof did not demonstrate that alternative methods of waste disposal were available to the site However, as part of its business operation, Petitioner does minor repair of its equipment on site and may include oil changes and other such services. Although Petitioner does not intend to pollute the groundwater and intends to use the proposed septic tank for office use only, the proof demonstrated that waste disposal into a septic tank from the maintenance and repair of its equipment could result in the disposition of prohibited hazardous waste into the groundwater. Further, the proof failed to demonstrate that the septic tank would be protected from use by those who handled the hazardous waste. Although the hardship, if any, caused by the denial of the variance was not caused by Petitioner and the proof failed to demonstrate reasonable alternatives of waste disposal, the potential for an adverse affect of the operation to the groundwater is great. Additionally, the proof failed to establish the ameliorating conditions of soil, water table or setback conditions or whether the property was platted prior to 1972. Accordingly, the denial of the variance was proper.
Recommendation Based on the foregoing findings of fact and conclusions of law, it is RECOMMENDED that a final order be entered denying the variance.

Findings Of Fact Fallschase is a special taxing district which was created by the Board of County Commissioners of Leon County, Florida, in Leon County Ordinance No. 75-6. The district contains approximately 620 acres and is located in the area of the intersection of U.S. Highway 90 and Buck Lake Road in Leon County, Florida. The Intervenors are corporations which are seeking to develop the Fallschase area into a residential community. Through its permit application, Fallschase is seeking authority to construct a 167,000 gallon per day sewage treatment plant which would serve the proposed development. The plant would be of the extended aeration type with tertiary filters. Effluent from the plant would be discharged into a Percolation pond system. The City of Tallahassee operates a sanitary sewer system which serves areas within the city limits, as well as many unincorporated areas of Leon County. Service is provided to the unincorporated areas of the county in accordance with a contract between the City and Leon County which was executed in 1973. No election has been conducted within Leon County to authorize the contract. The County has terminated the contract, but the termination will not be effective until November 12, 1980. The City's sanitary sewer system is a regional system in that it serves a broad area not limited by the political boundaries of the City. The City's system has operated under temporary permits issued by the Department for a number of years because it does not meet the Department's requirements for tertiary sewage treatment. The City's regional sewage treatment system is capable of providing service to Fallschase. A 10-inch sewage pipe known as the "Belle Meade" Line runs adjacent to Fallschase. If a pumping station were constructed, sewage from Fallschase could be pumped into the Belle Meade Line and eventually into the City's primary sewage lines for treatment at one of the City's treatment facilities. In accordance with its statutory responsibilities, the Department has adopted Rule 17-4.26, Florida Administrative Code, which relates to permit requirements for sewage works. As filed with the office of the Secretary of State, the rule provided as follows: No person shall operate, maintain, construct, alter, modify, or expand any sewage collection system, sewage disposal system or sewage treatment facilities without a current and valid permit from the Department, pursuant to the Provision of Chapter 17-6, Florida Administrative Code. The Department shall deny an appli- cation for a permit and refuse to issue a permit unless the sewage collection, treatment and disposal system will pro- vide adequate and effective treatment in accordance with the rules and regu- lations of the Department and unless the system will operate as part of a regional system if one exists or be capable of tying into a regional system should one be established. Applications for a permit under this section shall be in accordance with Part I, Chapter 17-4, Florida Administrative Code. (e.s.) As filed with the Secretary of State, the rule included a clear policy choice in favor of regionalization of sewage treatment systems. In accordance with its responsibilities, the office of the Secretary of State published the rule in the Florida Administrative Code. When the rule was published in the Code, the portion of the rule which is underlined in the above quote was omitted. The rule as published in the Code thus did not include a clear statement requiring regionalization, and does not make sense. This erroneous version of the rule has been published in the Florida Administrative Code for more than five years, and the error has been compounded in that the Department has utilized the Florida Administrative Code version of the rule in its official handouts. A citizen requesting a current copy of Rule 17-4.26 from the Department, or from the Secretary of State's office, would receive the erroneous rule. The error has been further compounded because the Department subsequently adopted a policy of evaluating applications for sewage treatment proposals without regard to whether hookups to a regional system were possible. This policy has been applied by the Department for at least three years in accordance with verbal and written instructions of the Department's then Secretary, Jay Landers. Additional language was later added to Rule 17-4.26 as follows: Except for regional treatment plants, as designated by approved metropolitan or basin plans, all permits for treat- ment plants shall be valid only until connection, according to an approved plan, can be made to regional facilities. Such connection shall be made within ninety (90) days of the scheduled date for connection as provided in the approved plan. This provision has no applicability to the City's treatment system because the City's system has never been approved as the metropolitan or basin clan by the Department. The City has contended that the sewage treatment plant proposed by Fallschase would result in violations of the Department's standards for nitrates in the groundwater in the area of the plant. Nitrates would be a constituent of the effluent which would be discharged from the proposed sewage treatment plant into percolation ponds. The engineer who has designed the proposed plant estimated that total nitrogen discharged into the percolation ponds would be approximately 20 milligrams per liter, or parts per million (p.p.m.). In extended aeration plants such as that proposed by Fallschase, a substantial portion of the nitrogen would be in the form of nitrates. The 20 p.p.m. estimate is high. The experience generally in north Florida has been that nitrogen concentrations would not exceed 10 p.p.m. in the effluent discharged into percolation ponds. Once the effluent is discharged into the ponds, a certain amount of nitrogen is removed during the settling process. As the effluent percolates through the subsoils into the groundwater, further nitrogen is removed. Estimates of nitrogen removal through these processes range from a low of 25 percent to a high of 75 percent. The groundwater below the proposed plant is classified as Class 1-B groundwater under the Department's rules. It is very unlikely that effluent reaching the groundwater would contain as much as 10 p.p.m. nitrates. Even if it did, mixing with the groundwater would cause an almost immediate dilution of nitrogen concentrations so that concentrations in the groundwater as high as 10 p.p.m. would be unlikely in the extreme. Many sewage treatment plants operate within the Department's northwestern region, which extends from Pensacola to Tallahassee. The Department monitors these plants. A violation of the Department's nitrate standards has never been observed in the region. Indeed, in the entire State of Florida, nitrate violations have been detected only in certain areas of Dade County. Testimony was presented by the City to the effect that chemical processes in percolation ponds can cause very drastic nitrate concentrations when the funds are intermittently flooded and drained. Such concentrations have been observed at one of the City's treatment plants. The City`s plant, however, is of a different sort than that proposed by Fallschase. The City's plant produces concentrations of nitrogen in ammonia compounds and utilizes intermittent drying and flooding of the percolation ponds as a part of its operation. Ammonia compounds will not be a major constituent of effluent placed in the Fallschase percolation ponds; and, furthermore, the ponds will not be intermittently flooded and drained in the manner that would cause such concentrations to develop. In its Notice of Intent to Issue the proposed permit, the Department indicated that sludge produced through the proposed treatment facility should be disposed of by hauling to a plant operated by the City. The City has indicated that it will not make its plant available for such disposal, and cotends that accordingly Fallschase has given no reasonable assurances that the sludge will be disposed of properly. The contention is without merit. Many alternatives exist for disposal of sludge. Fallschase has adequate area available to it for construction of sludge drying pits. Sludge can be hauled to many potential locations. Specific issues respecting sludge disposal can be addressed in the operating permit which would not be issued by the Department until it is established that the proposed plant can operate within the Department's rules and regulations. The soils which lie below the proposed percolation ponds are not of a highly permeable sort. To aid in the percolation of effluent through the ground into the groundwater, Fallschase proposes to construct two-foot diameter holes in the bottom of the percolation ponds. The holes would extend from 18 to 25 feet below the bottom of the percolation ponds. The holes would be filled with sand, and alternatingly coarse layers of gravel. The City has contended that these holes would constitute wells, and that they therefore would need to be permitted by the Department. This contention is without merit. These structures could fit loosely within the definition of a well, but their function is merely to aid in the percolation of effluent through the subsoils. They are not designed to inject effluent directly into the groundwater. These structures would constitute wells to the same extent that any drain field would constitute a well.
The Issue The issue for consideration in this case concerns whether the Petitioners are entitled to an on-site sewage disposal system ("OSDS") permit authorizing the installation of an OSDS on property which they own near the Suwannee River in Dixie County, Florida, in accordance with the permitting requirements of Section 381.272, Florida Statutes, and Chapter 10D-6, Florida Administrative Code.
Findings Of Fact The Petitioners are the owners of certain real property located in Dixie County, Florida, in the proximity of the Suwannee River. The property is described as Lot 38, Highpoint Suwannee Riverfront Estates. The lot in question is 82 feet by 141 feet in size and was purchased in April, 1988 for approximately $5000.00. The lot, and the subdivision it is in, was platted in 1983. On February 21, 1990, the Petitioners made application for an on-site sewage disposal system ("OSDS") permit, seeking to install such a system on this lot in order to be able to construct a vacation cottage on the lot The proposed cottage would contain one bedroom and would have a heated and cooled area of approximately 500 square feet. Upon reviewing the application, the, Respondent informed the Petitioners that they would need to have a surveyor establish the elevation of their lot, and particularly the site of the proposed OSDS installation, as well as to establish, through contact with the Suwannee River Water Management District, the ten-year flood elevation for the property. Accordingly, the Petitioners obtained a survey by `Mr. Herbert Raker, a registered land surveyor of Cross City, Florida. That survey shows a benchmark elevation of 13.09 feet above mean sea level ("MSL") That benchmark elevation is six inches above the actual grade surface of the lot so that the elevation at the proposed OSDS installation site is 12.59 feet above MSL. The ten-year flood elevation for the property is 15 feet above MSL, as established by data from the Suwannee River Water Management District contained in a report which is in evidence as Respondent's Exhibit 1. That flood elevation data was submitted to the Respondent by the Petitioners with the application for the OSDS permit. The property in question is located within the ten- year flood plain of the Suwannee River, and it is also located within the regulatory floodway of the River. On April 24, 1990, after advising the Petitioners of the denial of the OSDS permit application, the Respondent, by letter, advised the Petitioners that they should pursue a formal administrative proceeding rather than file an informal variance application before the Respondent's own Variance Board. The Respondent took the position that a variance could not be granted from the requirements of Rule 10D- 6.47(6), Florida Administrative Code, because the subject property was located within the ten-year flood plain of the Suwannee River and because of the Respondent's interpretation of the affect of the Governor's Executive Order 90- 14, which adopted by reference the Suwannee River Task Force recommendation that all such systems be prohibited within the ten-year flood plain. The Respondent thus declined to exercise its discretion, accorded it in the statute and rule cited hereinbelow, to entertain and consider a variance application. Finally, it is established that the lot in question is not subject to frequent flooding; but because the surface grade is beneath the ten-year flood elevation, the bottom of the drain field trenches absorption bed to be installed would also be beneath the ten-year flood elevation. In other respects, the property is a amenable to the installation of an effective OSDS because the wet season water table is 48 inches beneath the surface grade and would be more than 24 inches beneath the proposed drain field. The normal water table is approximately 60 inches beneath the surface grade. Appropriate limited soils are present beneath the first six inches of soil below the surface and consist of fine sand, light brown and brown fine sand, down to 60 inches, which is appropriate for effective subterranean treatment and disposal of sewage effluent. The Petitioners established a definite hardship on their part by the fact that they have paid a substantial sum for the lot and are now unable to develop it unless they receive entitlement to an OSDS or some reasonable alternative. In that regard, no sufficient proof of truly effective, reasonable alternatives was established by the Petitioners. However, they did establish that an anaerobic septic tank and drain field disposal system might be an effective alternative treatment and disposal method for the property in question. An aerobic system involves the injection of air into the attendant septic tank to support aerobic bacteria which break down and treat sewage at a faster, more effective rate than does the normal anaerobic bacteria-based system. The resulting effluent is substantially lower in BOD and suspended solids than is the effluent from the normal subterranean and anaerobic septic tank and drain field disposal system. The problem with such an aerobic system is that it involves mechanical equipment, especially, an external electric motor and pump to force air into the system. This is disadvantageous in that, if the equipment suffers a breakdown, then treatment and appropriate disposal of the effluent stops. The untreated sewage can then rise to the surface of the property or otherwise pollute ground or surface waters and potentially cause a public health hazard. Thus, such systems would require inspection periodically to insure that they are in adequate working order because if the mechanical system malfunctions, the system will continue to put effluent through its drain field without adequate treatment. In this circumstance, the occupants of the dwelling served by the system might not notice for long periods of time that it is inoperative because the system will continue to dispose of effluent, but just of an untreated nature. Accordingly, when the motor and air pump system becomes inoperative, there is less incentive for the owner to repair it. Thus, it is likely that if such a system were installed, some means would have to be found to insure that the owner keeps the system in good repair and working order. The means by which such an arrangement for insuring that such an aerobic system works properly at all times was not established in this record, however. Consequently, the Petitioners failed to establish that reasonable alternatives to the proposed conventional system exist and what they might consist of.
Recommendation Having considered the foregoing findings of Fact, Conclusions of Law, the evidence of record, the carndor 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 Petitioners' application for an OSDS permit.

Findings Of Fact On a site that would abut St. Johns County on two sides, the City proposes to develop as a landfill about 400 of the 880 acres it owns in the southeast corner of Duval County. The proposed southeast landfill is designed to serve the approximately 300,000 people living in Duval County south and east of the St. Johns River, by receiving 1,700 tons of solid waste a day for ten years, 400 or 500 tons a day more than people in that part of the city now generate. Sandhill and Swamp Scattered over the portion of the property proposed for solid waste deposition are cypress marshes and blackgum sloughs isolated from a swamp and from each other by upland pine plantation and sandhills. Except for some 40 acres cut off from the remainder by a fill road, the hardwood swamp covering approximately 265 acres of the City's property is part of the pristine "Durbin Swamp system which is a major wildlife area, including habitat for threatened and endangered species." T. 2820. Durbin Swamp south of J. Turner Butler Boulevard and east of U.S. Highway 1 is "the most valuable wildlife habitat in the area, maybe in the southeastern United States." T.2921, 3058. The City's consultants characterized 64 of the 123 gopher tortoise burrows they found on some 105 acres in the southern part of the site as active. Sherman's fox squirrels feed and nest on the property. Although "very little of the sand hill habitat [remains] in its natural condition on the property," (T. 185) turkey oak, long leaf pine and sand pine communities do survive. Isolated wetlands scattered through the eastern portion of the site have also been timbered, and ditches intersect many of them. St. Regis Paper Company, who owned the land until earlier this decade, "dug a series of canals . . . to drain . . . part of the land ["it was called upper wetlands"] . . . so that the ground could be high enough to raise good grade pine trees." T. 1417. "The isolated wetlands . . . provide habitat diversity for wildlife, a seasonal source of drinking water, possible refuge during forest fires, as well as breeding and forage locations," (T. 1255) according to the City's draft application. "Wildlife noted on the site includes Florida black bear, white-tailed deer, raccoon, armadillo, cottonmouth, river otter, common night-hawk, alligator, yellow bellied sapsucker, turkey, frog, quail, dove and red- shouldered hawk," (T. 1255) also according to the City's draft application. Bobcats are common. According to the St. Johns River Water Management District's chief environmental specialist, "animals that you would find utilizing the uplands . . . would be a range of small rodents [including] mice, rabbits . . . insects, [mostly tree] frogs, toads, snakes [including] black snakes, rat snakes . . . [o]possums . . . pastorine birds, cardinals, bluejays, blackbirds . . . [and] probably some hogs." T.537-8. Wood storks wade and feed in the isolated wetlands on site. Wood stork rookeries have been found five miles to the southeast and seven miles north of the City's property. Bald eagles nest nearby but off site. Eagles used the now abandoned eagle nest on Eagle Nest Island "three-quarters of a mile from this proposed landfill site," (T. 1419) at least as recently as 1983. One or more eagles still perch on a dead cypress limb on the property (T. 2422), if not elsewhere on site. Ospreys, southeastern American kestrels (T.2918) and six or seven species of woodpeckers, including the rare hairy woodpecker (T2914) have also been seen on site. "There are dirt logging roads just as there are in any property in Florida, but not a great number." T. 2751. "Almost all of the pine flatwoods habitat on the site has been replaced with planted pine." T. 184. The property is comparable to the Wacasassa tract in Gilchrist County which is on the Conservation and Recreational Lands list and under consideration for state acquisition because of its "comparatively unaltered nature." T. 2721. In the past, conservation efforts have brought animals to the property for refuge. T. 1420. Listed Species The Florida Game and Freshwater Fish Commission (Game and Fish) lists the gopher tortoise and the Shermans's fox squirrel, said by one witness to be "imminently threatened," (T. 2899) as species of special concern. T. 2875. A species of special concern "is beginning to show a decline and needs to be . . . considered as a target of conservation and if present conditions continue it's going to be listed as threatened." T.2874. Game and Fish lists the Florida black bear, the southeastern American kestrel and the bald eagle as threatened, the same category in which the United States Fish and Wildlife Service (Fish and Wildlife) lists the American alligator. A threatened species is one destined to become endangered "if present trends continue." T.2874. Both Game and Fish and Fish and Wildlife list the wood stork as endangered, and Fish and wildlife lists the bald eagle as endangered. "An endangered animal is one that under present conditions is in danger of becoming extinct in the near future." T.2874. Listed in the Convention on International Trade of Endangered Species are the bobcat and the river otter. By definition, rare animals are not often seen in the wild. The parties stipulated that the staff of CZR, Inc., a consultant engaged by the City, spent an aggregate of 1400 man-hours on the landfill site, of which 429 man-hours were spent on site for the purpose of performing a wildlife survey. T. 2803. Despite their effort and putative expertise, the City's consultants did not see even a single listed animal. This failure contrasts with sightings by hunters and other experts who spent less time on site, and may be attributable to the time of year (two weeks in the fall) the survey was performed (T. 2425-27, 2893, 2899) or to the way in which it was done, (T. 2429, 3067, 3068) which a wildlife ecologist testified rendered it of "trivial value." T. 3079. The study was expedited in anticipation of a hearing date. T. 2426-27. In any case, the survey does not give reasonable assurance that species whose range includes the City's property are not present in suitable habitat on site. T. 2896-97, 3079-80. This is, indeed, the conclusion the City's own experts reached as regards the gopher tortoise itself, because of the clear sign these creatures' burrows give of their use of the property. Similarly, with respect to the Sherman's fox squirrel, although only a single individual was spotted, distinctive nests and piles of pine bracts on site established their presence. Bear tracks corroborate infrequent sightings on the property, as well as south and east of the site. On a large tract of land to the north, bears are fed daily; three or four feed each day. T. 2421. Alligator sign bore witness to the alligator's use of the property, although the only sighting clearly proven at hearing occurred just across the boundary line. Of course, wildlife does not respect legal boundaries. There is no reason not to believe that the red-cockaded woodpeckers, with six active nests within three miles or the Bachman's sparrows heard singing nearby do not frequent the City's property, which offers suitable habitat for both. It is even possible that the Florida panther, common in the area as recently as 30 years ago, may have roamed the site in more recent years in pursuit of deer or feral hogs. Two witnesses swore they had seen Florida panthers within two miles of the site, one only a few months before the hearing, (T. 1362, 1371, 1419), and a third testified he thought a "cat" he had seen two and a half or three years before the hearing just north of the site was a Florida panther. T.2429-32. The Florida Everglades mink, a threatened species according to Game and Fish, has been spotted at least twice in a cypress bog across the street from the City's property, and probably occurs on the property, as well. Not spotted either on the City's property or on adjacent land, the Florida mouse, the eastern indigo snake and the gopher frog are known to make their homes in gopher tortoise burrows. Of these listed commensal species, the indigo snake is particularly likely to inhabit the site. "The blue indigo snake was turned loose on that property in . . . '81 or '82, since it was an endangered species." T. 1420. The site also affords suitable habitat for the long tailed weasel, under review for listing. Game and Fish has listed the Florida mouse and the gopher as species of special concern. Bachman's sparrow is under review for listing. Fish and wildlife views both the red cockaded woodpecker and the Florida panther as endangered, while Game and Fish views the latter as endangered but the former as threatened only. Aquatic or Wetland Dependent An "aquatic and wetland dependent" species is a species that "requires wetlands or aquatic systems to satisfy some critical biological need in its natural life cycle," (T. 524) apart from simply drinking water. "[W]ithout wetlands or aquatic systems, these species would probably be extirpated from the state." Id. The Sherman's fox squirrel, the gopher tortoise, the Florida mouse, the Florida long-tailed weasel, the southeastern kestrel, and Bachman's sparrow are not aquatic or wetland dependent. Because they use watery environments for feeding, reproduction and other purposes, the alligator, the wood stork (the only stork in North America) and the gopher frog are aquatic and wetland dependent. Because "the whole black bear population in our state seems to shift . . . primarily in the fall and winter months, to the wetlands and . . . eat . . . fruit produced in wetland trees," (T. 527) the black bear is deemed wetland dependent. The indigo snake is also so classified because it "seemed to be heavily dependent upon eating frogs." (T. 526). Even though not wetland dependent "historically and naturally," (T. 527) the "less than probably 100 Florida panthers left in the state" are now so viewed because "they have more or less been restricted to the major swamp systems," id., without which they probably would not survive. The contiguous wetlands on site comprise the headwaters of Durbin Creek, which empties into Julington Creek shortly before Julington Creek reaches the St. Johns River. Large scale residential development of lands lying within the watershed of Durbin and Julington Creeks has been proposed. Durbin Creek and the swamp that gives rise to it serve as a "juvenile fish nursery" (T. 2468) for white shrimp, blue crabs, croaker, anchovies, bream, bass, shellfish, bluegill, and sheepshead. Lower dissolved oxygen levels or other stressors in Durbin Creek would decrease populations in fisheries already at carrying capacity, and already threatened by the prospect of overdevelopment. Dredging and Filling The City intends to build a road running east and west between the landfill site and U.S. Highway 1 following, for the most part, an existing dirt logging road, and crossing Old Kings Road, built in 1765 to connect the capital of colonial Georgia with St. Augustine. Turbidity screens and staked hay bales would be used during road construction to protect adjacent waters. After construction, seeding and mulching would stabilize the sloping shoulders of the fill road. In connection with construction of the access road, plans call for filling wetlands contiguous to Durbin Swamp, 2.8 acres within DER's jurisdiction and 3.5 acres within St. Johns River Water Management District's jurisdiction. Fetterbush, gallberry, scrub palmetto, cinnamon fern, bamboo vine and sphagnum moss grow in these contiguous wetlands, under a canopy of slash pine, loblolly bay, cypress and swamp tupelo. The proposed Class III disposal area would lie two hundred feet north of the south property boundary and 600 feet west of the east boundary. Over significant portions of this 88-acre site, fill dirt is to be used to raise the grade, because the land is so low. Enough fill is to be placed in the marshes and sloughs to avoid depositing solid waste in the water. Trucks would haul fill dirt to the eastern part of the site ("the area starting at the northeast corner of the Class III landfill and extending about 300 feet to the west, starting from a point about midway along the eastern margin of the landfill, and extending about 450 or 60 feet to the west, and along the southern portion of the Class III landfill, about . . . 600 feet" T. 1562) and elsewhere on site, smothering isolated wetlands, where more or less healthy vegetation, generally of the kind found in the contiguous wetlands, now grows. The 132-acre Class I disposal area, which would abut the Class III area on the north, would also cover isolated wetlands now on the site. Together with excavation of associated stormwater retention basins, the disposal areas would disturb a total of 46.3 acres of isolated wetlands within the St. Johns River Water Management District's jurisdiction. The St. Johns River Water Management District originally asserted jurisdiction over 48.5 acres of isolated wetlands, City's Exhibit No. 80, but the objectors offered no evidence that staff's subsequent decision that vegetation on one 2.3-acre parcel did not qualify was erroneous. This total does not include isolated wetlands less than half an acre in extent or isolated wetlands lying both within and without the disposal areas which will cease to function as such when truncated by dredging or filling. In this latter category are some ten acres that will not themselves be dredged or filled. T. 2777-8. St. Johns River Water Management District identified 5.3 acres of high quality isolated wetlands with connections off-site that are to be impacted, City's Exhibit No 80, along with another 11.2 acres of "low quality" isolated wetlands. Id. No stormwater retention basin would intrude into DER's jurisdictional wetlands, but approximately nine tenths of an acre falling within the St. Johns River Water Management District's contiguous wetlands boundary would be devoted to stormwater retention basins. Replacement Wetlands To mitigate the planned filling of contiguous wetlands for construction of the access road, the City proposes "to excavate 3.5 acres of nonjurisdictional pine plantation and create a contiguous swamp wetland." City's Exhibit No. 56. Mature dahoon holly, loblolly bay, cypress and gum trees "will be transplanted from on-site [isolated] wetlands proposed for construction impact." Id. A tree spade is to be used to transplant trees with trunks as much as 12 inches in diameter at "breast height" and up to 50 feet tall, along with existing soils, microbial communities and adjacent understory vegetation. The "physical structure of the trees themselves . . . provide a good deal of the habitat." T. 436. Removing mature trees from isolated wetlands and replanting them in created wetlands would, to some extent, mitigate the loss of perches for bald eagles and other birds. Mature trees in the created wetland would be replanted at a density "approximately half that of existing on-site wetlands to be impacted." Id. Only 80 percent of the replantings are to be replaced, if they die; and then only if it is clear within three years that replacement is needed. A six-inch layer of organic soil, to be spread after the trees have been transplanted, would "provide for growth of herbaceous vegetation." Id. The City would monitor the created wetland (part of mitigation area "A") for three years and transplant additional trees, if needed to assure survival of not less than 80 percent of the number of trees originally planted. Of these 3.5 acres, the City has identified 2.8 as specifically intended to mitigate the filling of wetlands within DER's jurisdiction. With respect at least to this portion, the created wetland "will function probably much the same as the 2.8 acres" (T. 2765) to be filled in constructing the access road and "would compensate for the" (T.2765) attendant loss of vegetation. In transplanting mature hardwoods, "[i]t's sort of a physical impossibility to get all the root material . . . [and y]ou also get some loss of branches, limbs and stems just from the physical movement of the tree." T. 2482-83. One reason a wetland "system stays wet . . . is a thick canopy." T.2486. With more sunlight streaming through a sparser canopy, the "vegetation is not going to be the same." T. 2487. "[B]ecause you don't expect the wetlands to function as well as the original wetlands you're replacing, there is a general rule of thumb that . . . you create twice as much wetlands as the wetlands you've destroyed." T. 2488. "A three-to-one ratio would not be unusual for a good mature forested hardwood system." T.467. St. Johns River Water Management District's Applicant's Handbook calls for a ratio between 2:1 and 5:1, but states: "The ratios may also be adjusted when wetlands creation is combined with wetland mitigation proposals such as an open buffer area adjacent to the wetlands, conservation easement, wetland enhancement proposals or alternative mitigation proposals." T. 504. The ratio proposed here is less than one to one. In all, mitigation area A would comprise 11.0 acres of what is now pine plantation. Aside from a .55 acre pond in the middle, mitigation area A would consist of wetlands contiguous to existing wetlands on which three different, if related, vegetative communities are to be planted. In addition, the City proposes to create three different isolated wetland areas, one of which (mitigation area D) it characterizes as "high quality." Six acres of what is now pine plantation would be excavated on the north edge of the property. Using the same, experimental techniques proposed for mitigation area A, cypress trees would be placed on 3.4 acres, and 2.6 acres would be devoted to a combination of loblolly, cypress and dahoon holly. Another 9.8 acres of isolated wetlands would be created within borrow pits, 6.8 acres in borrow area No. 1 (mitigation area B) which would include .55 acres of open water, and 3.0 acres in borrow area No. 2 (mitigation area E.) Just north and east of the truck scales, mitigation area B would receive 200 adult trees per acre planted to the extent they are available on site, or 400 trees per acre planted with nursery stock. The same density is planned for mitigation area E, to be located across the road from stormwater retention basin 4. The City also proposes to remove a segment of a logging road built on fill that now cuts off 40 acres from the remainder of Durbin Creek Swamp. Removal of the fill and revegetation would not only increase the extent of the swamp by 0.3 acres, it would restore historic sheet flow in that part of the swamp. Finally, the City proposes to spread muck, if available, over the shallow, southern part of stormwater retention basin 2 and plant 12 acres of grass ("[w]etland herbaceous species" City's Exhibit No. 80) which, however, the City reserves the right to dredge up "from time to time". Id. p.13. Other Effects, Other Mitigation Building and operating the landfill on the site proposed would displace upland wildlife and fragment largely undisturbed and undeveloped wildlife habitat. Fences along the northern, eastern and southern site boundaries would present a physical barrier. Human activity, particularly daytime traffic on the access road, would also create a "bio-geographical barrier." Developing a landfill at the edge of the swamp amounts to "leapfrogging," instead of expanding existing pockets of industrial or other development. A witness characterized the area to the south of the site as "rural developed"; some 164 people live within a mile of the center of the site. T. 78. But private ranch lands to the north, like undeveloped land to the east, afford good wildlife habitat. Habitat fragmentation divides and isolates animal populations. "Fragmented populations are more susceptible to disease, inbreeding and with time, poaching." T. 2890. The landfill would displace gopher tortoises, their commensals, if any, and other wildlife using sandhill or pine plantation habitat, as well as wildife, including wood storks and other migratory birds, making use of the isolated wetlands that are to be filled over. With the filling of isolated wetlands, migratory birds would lose holly berries and other forage. Filling or excavating acreage at the periphery of the swamp would also destroy habitat and displace wildlife. Wildlife now on site reaching suitable habitat elsewhere will have to compete for limited space against animals that have already established territories. The result should be a net decline in populations. T.2898. Increasingly sequestered, the Durbin Swamp system is already under pressure from urbanization to the north. For animals that remained in the vicinity, development of the landfill would occasion other difficulties. But evidence that landfill noises and odors "would have no discernible impacts to the value of wetlands as habitats for aquatic and wetland dependent species" (T. 528) went unrebutted. A buffer of at least 50 feet would separate contiguous wetlands from stormwater basins and other construction, but this is considerably less than the 528 feet Dr. Harris testified was necessary to avoid "greatly erod[ing] the native faunal diversity of the Durbin Swamp wildlife." T.3073-74. Placement of the landfill on this site would increase the numbers of a half dozen "middle-sized mammal omnivores" (T. 3078) so that gopher tortoises, turkey, quail, "anything that nests on the ground will be subject to the plundering by the enhanced population of raccoons, opossums, gray foxes, red foxes . . . and such." T. 3079. Increased numbers of armadillos would also pose a heightened threat to animals that nest on the ground. Landfill operations can be expected to attract seagulls and birds of other species, including nest predators and the brown-headed cowbird, which takes over other birds' nests to lay its own eggs (T. 3071-2) and would pose a particular threat to Swainson's warbler. It is not clear that any of the mitigation areas the City proposes is intended to replace wood stork feeding habitat that would be lost to dredging and filling. Wood storks feed on dense fish populations in shallow water, when receding water levels make the fish easier to catch. Isolated wetlands on site that have served this function would be lost (T. 2419), although not all of the isolated wetlands to be lost have enough water to support the kind of fish on which wood storks prey. The deep, steep-sided ponds planned for the mitigation areas do not replicate the necessary conditions. Whether birds may safely feed in or drink from untreated stormwater run-off in shallow portions of the retention basins is doubtful. When it rains, particularly the initial flush of run-off would deliver pollutants, including oil, greases and gasoline left by garbage trucks, to the retention basins. T. 1820-1. Removing the fill road and restoring normal flows to the 40-acre patch of the swamp on the other side, as the City proposes, would not add to feeding areas available to wood storks, except for the 0.3-acre roadway itself. The project would disrupt "very superior black bear habitat." T. 3059. Tending to avoid human activity, bears would likely range further east, foregoing foodgathering on site. On the other hand, food or other refuse brought to the landfill might lure bears to their deaths, intentional or accidental. "[C]ollisions with human vehicles," (T. 3062) is the chief cause of black bear mortality in Florida. Bears have been killed in this fashion within a mile of the site, (T. 351 1411-4, 2438) although not during daylight hours when the landfill would be in operation and garbage trucks would travel the access road. Creation of wetlands will not mitigate destruction of upland habitat. On the contrary, additional upland would be taken to create the wetland mitigation areas planned. But the City proposes to give a conservation easement on 129 acres of upland, adjacent to the swamp, that is to remain undeveloped. The upland easement would preclude a host of uses inimical to wildlife, and would mitigate to some extent the loss of wetland habitat for animals which use both uplands and wetlands, like the black bear, even though cut over slash pine plantation is among the very least important or productive wildlife habitats in Florida. The easement would not include sandhill habitat. The City has also undertaken to give a conservation easement covering some 260 acres of wetlands contiguous with Durbin Creek Swamp. This would not, of course, increase the extent of existing wetlands, but it would add a measure of protection for those that survived the project. Perhaps most importantly the wetland conservation easement would preclude expansion of the landfill further into the wetlands, as long as it remained in force. Existing regulatory restrictions on the use of wetlands prevent many uses, even without an easement. Apparently no regulation precludes harvesting bottomland hardwoods, however, so long as no excavation is involved, and vegetation, once severed, is not redeposited on site. But converting deforested areas to pinelands, without a permit from the Army Corps of Engineers would probably not be authorized, under 33 U.S.C. s.1344 (f)(2). See Avoyelles Sportmen's League, Inc. v. Marsh, 715 F.2d 897 (5th Cir. 1983). The City proposes to relocate gopher tortoises and any indigo snakes, gopher frogs or Florida mice that can be found to an unspecified new home off- site. Survival rates for gopher tortoises after similar relocations in the past have ranged between 30 and 100 per cent. By the year 2,000, the St. Johns County gopher tortoise population is predicted to fall by 90 percent, and Duval County is predicted to be devoid of gopher tortoises, even without relocation efforts of the kind proposed. Some or all of the gopher tortoises slated for removal may be descended from those who were brought to the site from Lake City. Perhaps even some who started out in Lake City would themselves make this second exodus to a new promised land. Stormwater Management The site proposed for the southeast landfill does not lie within a basin for which the St. Johns River Water Management District has adopted volumetric requirements. A "set of double [triple (T.1740)] box culverts five feet by eight feet . . . and . . . four other," (T. 425-6), "equalizer culverts," large enough for bears to move through (T. 415) would convey preexisting surface flows. A cross drain in the vicinity of the service plaza would serve the same function. Flood elevations would not increase more than a foot immediately upstream or more than 0.1 feet 500 feet upstream. The access road would not impound surface waters. Exfiltration trenches paralleling the access road "designed based on South Florida's criteria" (T. 1737) would filter contaminants from water running off the road. Within 72 hours of a 24-hour, 25-year return storm, the exfiltration system would be able to treat twice the volume of stormwater that recurrence of such a storm would generate. T. 1743. The scale plaza area where garbage trucks moving east on the access road would be weighed before being directed further down the road to a disposal area, is to be built on an upland portion of the property, and with it a wet detention pond to which surface water from the plaza and associated roadway would drain. Swales and berms would divert surface flow from undeveloped parts of the property that might otherwise reach the detention pond. The interceptor ditch and associated works would reduce by 2.5 hours the time of concentration for runoff from a 202-acre watershed, but cause no other changes in watershed characteristics. A weir would make it possible to regulate overflows and allow detention of run off long enough for biological assimilation of most pollutants. For the 25 year return, 24-hour storm, the pre-development peak rate of discharge (6.3 cubic feet per second) is less than the post-development peak rate without detention (18.4 cubic feet per second) but more than the post- development peak rate of discharge with detention: 3.9 cubic feet per second. An orifice below the weir, with a diameter of 1.5 inches, is designed to discharge less than half the treatment volume (22,088 cubic feet or 2.5 inches times the impervious portion of the area drained) in 64.21 hours. The design meets DER and St. Johns River Water Management District criteria. Portions of stormwater retention basins 1 and 2, situated north of the disposal areas, would lie within the 100-year flood plain. These two retention basins are designed to receive stormwater running off the Class I site or diverted around the site, as is stormwater retention basin 3, while stormwater retention basin 4 is intended to collect stormwater flowing off or around the Class III disposal area. Stormwater retention basins 3 and 4, like the southern area of stormwater retention basin 2, are not to be excavated to a depth of more than five feet below grade, to prevent groundwater from seeping into stormwater retention basins, dewatering the wetlands where it would otherwise emerge. With terraces at 20-foot intervals, to a height of 60 feet above grade for the Class I site and 40 feet above grade for the Class III site, both landfills would resemble Mayan temples, at build out. Ditches around the perimeter of each terrace are designed to convey stormwater to slope drains which would bear water to the level below, eventually to the perimeter ditch on grade, from which it would flow, through box culverts under roads built around the landfill, into the retention ponds. To the extent necessary to prevent groundwater infiltration, the ditches are to be lined. Stormwater retention basin 2 has two discharge structures, while each other basin has a single discharge structure leading to a ditch that would convey stormwater to Durbin Swamp. Perforated pipes, swathed in filter cloth, would be buried under highly permeable sand, along the sides of the retention ponds. Installed above seasonal low groundwater elevations, in order to avoid draining groundwater from the area around the ponds, during dry seasons, (T. 1781) they would have to go below seasonal high groundwater elevations, in order to be low enough to serve as drains for the retention ponds. Ambient groundwater would seep into the pipes, whenever groundwater levels outside the ponds rose above the pipes' elevation. But the pipes would still be able to drain the retention ponds, because of the relatively greater (vis-a-vis soils on site) hydraulic conductivity of the highly permeable sand to be trucked in for use as a filter medium. In time, these side drains or underdrains would clog and require expensive maintenance. But, assuming proper maintenance of the retention pond drains and of the drains that make up the roadway exfiltration system, the landfill and associated development would not flood or dewater wetlands that are not themselves to be dredged or filled. Except what is lost to evaporation, water entering the retention ponds would reach the wetlands, whether through the underdrains, over the weirs and through the conveyance ditches, or by movement underground after seeping through the bottom of the basin. The post-development peak rate of discharge from the area draining into the stormwater retention basins should not exceed pre-development rates for a 24-hour 100 year return storm or any lesser event. Because of roads and other impervious surfaces, a greater volume of surface water should reach the wetlands, causing stages about two inches higher than under pre-development conditions in "a typical summer thunderstorm." T.1782-3. The increase in surface flow corresponds to a decrease in water percolating down into the groundwater, and may result in additional loss to evaporation of water that would otherwise reach wetlands. But any such effect will be slight; surface and groundwater levels and surface water flows will not be adversely affected. T. 1783. Nor will existing surface water storage capabilities be adversely affected, despite the placement of portions of retention basins 1 and 2 within the 100-year flood plain. This encroachment at the very edge of the flood plain would rarely have any effect on surface water flows. Almost all development is to occur outside the ten-year flood plain. The stormwater basins could hold an inch of runoff without discharging water over the weirs. The underdrains, which would, when originally installed, have a hydraulic conductivity of about 130 feet per day, could remove an inch of run-off within approximately 40 hours. On the conservative assumptions that half of a two-foot vadose zone would already be saturated at the time a 24-hour, 25-year return storm dropped an additional 8.9 inches of rain on site, and that soils on site have a porosity of .5, the retention ponds could contain the resultant run-off for treatment, before discharging it first through weirs then through the underdrains. Three surface water monitoring stations are planned. One upstream would make it possible to assess background conditions. Another at the point of discharge from stormwater retention pond 2 would reveal whether the retention ponds and their sidedrains were functioning as intended. A third monitoring station in the southwest corner of the site should give similar information as to the roadside exfiltration system. Hydrogeology Except in the southeastern corner of the City's property, where the ground slopes down to the east, the land the City owns, like the adjacent land to the south owned by the McCormicks, slopes down in a more or less northwesterly direction, falling from 55 feet NGVD on the southern boundary to 15 feet NGVD at the northwest boundary, which intersects an elbow of the swamp. Although groundwater flows east of north under the southeast corner of the property, the flow under the property is generally northwesterly, following the topography. Class II groundwater in the surficial aquifer underlies the property at depths ranging "from almost to land surface to five or 10 feet below." (T. 1517). City's Exhibit No. 161. Groundwater flowing northwesterly crops out in isolated wetlands, evaporates, transpires or discharges into the swamp. To assure that the bottom of each exceeds seasonal high groundwater levels, measured in February of 1987, by the number of inches a 24-hour 25-year return storm would add, fill would be placed under both disposal areas, as needed. Because the Class I solid waste disposal site is to be lined, recharge by rainfall would be precluded there. With a liner intercepting percolating rainwater, groundwater would not attain predevelopment levels. The depression thus induced under the Class I site would more than offset the tendency groundwater under the Class III site would otherwise have to mound up into the bottom layers of solid waste deposited there. Recharge from rainfall (become leachate) would continue at the unlined Class III site; the height of accumulated waste would slow or stop evapotranspiration offsetting percolation there. But groundwater would flow down steeper gradients to lower levels underneath the Class I site (which lies between the Class III site and the wetlands where groundwater discharges) rather than rising into waste disposed of on the Class III site. The horizontal component of flow would continue to exceed the vertical component by several orders of magnitude. Beneath the surficial aquifer, which extends to depths of 50 to 100 feet below ground and consists of sand interspersed with a "matrix of soil, organic materials, clays and silts . . . little layers of clay and hardpan" (T. 1517) lies a continuous, confining layer of gray, sandy material with gravel and shell fragments, 12 to 40 feet thick, blanketing the undulating surface of the Hawthorne formation underneath. "[S]ome 40 percent of the material comprising the Hawthorne formation in this area is clay and the remainder is a mix of sands, silt stone, shell beds and phosphatic sands." (T. 1526) This assures that rainfall or other fluids percolating into the surficial aquifer on site will move horizontally downgradiant, reentering the atmosphere or discharging to the surface, rather than penetrating the thinner aquitard above the Hawthorne formation and sinking another 250 feet or more through the Hawthorne formation itself into the Ocala group and Floridan aquifer below. No subterranean feature in the vicinity permits water in the surficial aquifer to reach the Floridan. No peat, muck or other unstable soils underlie the site. Under 3,000 pounds per square inch, the maximum load anticipated, the ground is not expected to settle more than one inch. The addition of fill dirt does not alter this estimate significantly. Disposal Design The Class III disposal area would not have a liner, a leachate collection system or gas controls. After travelling through soils under the site, leachate from the Class III site would enter the groundwater. The City proposes to train and direct staff, to the end that only yard trash and construction and demolition debris end up in the Class III disposal area, where waste would be deposited directly on fill dirt or naturally occurring soils. No solid waste is to be disposed of within 200 feet of wetlands contiguous to Durbin Swamp lying within DER's jurisdiction. A composite liner of the kind in place at Alachua County's southeast landfill would form the corrugated bottom of the Class I landfill: a 60 mil high density polyethelene layer overlying two six-inch lifts of calcium montmorillonite, a clayey sand that is to be placed on compacted subgrade configured in "a herringbone design with peaks and valleys." T.765 Separating trenches in the valleys, sloping ground would rise, then fall at least two feet for every hundred horizontal feet. Steps would be taken to remove rocks, twigs, roots and the like, before compacting subsoils on site. A machine called a sheepsfoot is to be deployed, once half the montmorillonite has been put down, to pulverize clods and mix the material, in an attempt to assure uniformity within each lift of clayey sand. Other machines would compact each lift to a specified Proctor density. These efforts would not succeed in eliminating all clods or other imperfections, and the sheepsfoot would mix subgrade with the bottom layer of montmorillonite, introducing new impurities. Soils on site have hydraulic conductivity ranging from 1 x 10-3 to 1 x 10-4 centimeters per second. Clayey sand is also subject to desiccation cracking; as it dries out, large cracks appear. On top of this kneaded, compacted and finished 12-inch layer of clayey sand, once it had been inspected to assure the absence of roots, rocks, sticks, glass or other sharp objects, a specialty contractor would unroll strips of unreinforced high density polyethylene. After arranging the panels to minimize seams in the leachate collection trenches, technicians would weld the polyethylene strips to one another. An independent, third-party quality assurance contractor would inspect and test the seams before the synthetic liner was finally positioned, and as flush a fit as possible was achieved. Both the high density polyethylene and the quality assurance program are to meet the requirements of NSF Standard 54 and EPA Publication SW-870, March, 1983. Some wrinkling and occasional flaws in the plastic liner are inevitable. Wrinkling causes ponding, not only of rainwater during construction, but also of leachate, once the landfill is in operation. Tire tracks or other indentations in the montmorillonite layer can also cause ponding. In time, under the growing weight of solid waste, and with heat that biodegradation of the waste would generate, some of the wrinkles might subside, but the liner might also sink into additional depressions. Careful construction could keep ponding to a depth of little more than an inch. T. 2971, 2979. Extrusion welds (when done properly) render the seams stronger than the panels they join. But even if "you are really, really good" (T. 2957) and even when you're careful you get an occasional problem, one or two per acre, no matter how careful you are. And if you're not as careful, you get more, typically something on the order of five holes per acre. T. 2967 Carelessness on one project resulted in as many as 60 flaws per acre. Nondestructive testing methods do not detect all defective welds. T. 2966. Defects may develop after the plastic liner has been inspected. Stress on high density polyethylene associated with "conform[ing] itself to whatever is underneath it" (T. 2962) concentrates in scratches, gouges and crimps to cause "as much as 30 percent" (T. 2964) of the holes in the material. "[T]here is no shortage of scratches on a construction site." T. 2962. Leachate Collection Another high density polyethylene geotextile, chosen for its transmissivity (the geonet), is to be placed on top of the high density polyethylene liner (the geomembrane), where it would act as a synthetic drainage medium. In order to prevent overlying sand's clogging the geonet, compromising its ability to conduct leachate down into the trenches, a third, highly permeable geotextile, "a non-woven needle punched type" (T. 637) (the geofilter) would go directly on top of the geonet. The twelve-inch sand drainage layer blanketing the geofilter would have hydraulic conductivity of 1 x 10-3 centimeters per second, if sufficient quantities of suitable sand could be obtained. (T. 764) Another 12 inches of native soil is to cover the sand drainage layer. While the geofilter and the soil layers above it would parallel the landfill liner on the slopes between trenches, they would form arches over the trenches themselves. Continuing to follow the contours of the montmorillonite, the geomembrane and the geonet would line the trench bottoms. Below these arches, inert drain field rock would fill the lined trenches, supporting one perforated PVC pipe eight inches in diameter in each trench. The Class I landfill is to be built in fourteen 250-foot wide cells, with each cell having two leachate collection pipes on 125-foot centers. Manholes at either end of each leachate collection pipe would allow access, in case unclogging the pipe proved necessary. Longitudinally, the trenches would slope to the north, falling two to 20 feet for every 1,000 horizontal feet. Leachate reaching the trenches would flow along the trench bottoms (or through the pipes) to the manholes on the northern boundary. Also to be made of leachate-impervious PVC, leachate drain pipes, which would not be perforated, would connect all manholes on the northern perimeter. Varying in diameter from eight to twenty inches, depending on the number of manholes they were designed to empty, they would converge at a leachate pumping station north of the perimeter road. T. 590-1. A rupture in one of the single-walled leachate drain pipes could spill massive quantities of leachate on naturally occurring soils. Leachate which reaches the station is to be pumped into a 12,000 gallon storage tank nearby. To be mounted on a concrete slab surrounded by a curb high enough to contain all 12,000 gallons, if the tank failed, the tank would be constructed of high density polyethylene. The plan is to pump leachate from the tank through a four-inch discharge pipe into tanker trucks which would take the leachate to the Buckman wastewater treatment plan for disposal there. During "the maximum leachate production period, when you have 10 cells open," (T.687) an average of 35,000 gallons of leachate a day would require removal for disposal in this fashion. Additional tanks could be built. As a precaution, isolation valves would permit cutting off all flow of leachate to the pump station. In addition, isolation valves would allow cutting off the flow from any of seven pairs of cells (or slowing the flow from all, T. 705) in the event of an abnormal circumstance where leachate production in the facility exceeds the hydraulic capacity of [the] leachate removal system, the pumping station and storage tank and the tanker truck system. T. 591. Isolation berms separate each pair of cells susceptible to being put to use as temporary storage for leachate. The leachate drain pipes themselves afford more than 23,000 gallons of emergency storage. T.703. Ventilation As they decompose, materials to be deposited in the Class I landfill produce methane gas, carbon dioxide, and other, malodorous gases. Collection pipes with eight-inch diameters, running horizontally on 150-foot centers in the second and fifth lifts would allow gas to escape at either end, on the north and south sides of the landfill. This would prevent methane's building up and exploding or catching fire. By assuring their gradual release, it should also minimize the impact of foul smelling gases, which, in any event, are generally undetectable at a distance of more than 1,000 feet. But specific condition eight of the proposed landfill permit requires that the passive system be converted to an active system, if necessary, using vacuum suction and flaring. GIGO Although there "is not much industry in the southeast portion of Duval County," (T. 953) sewage sludges and other industrial wastes "except any hazardous waste as defined in the Federal Register" (T. 947) would be accepted for disposal at the Class I facility, if properly manifested. The proposed southeast landfill would receive waste that would otherwise have gone to the unlined east landfill. Household waste contains toxic materials. Tests of leachate generated in other lined landfills from which hazardous wastes are excluded have demonstrated the presence of some 30 metals and 56 organic compounds. City's Exhibit No. 89. Rainfall percolating through (and moisture already present in) waste deposited at the proposed Class I facility can be expected to leach the same array of substances from materials deposited there. Judging from experience elsewhere, leachate from the Class I facility would contain 13 or 14 (if 4-methyl phenol is included) substances in concentrations in excess of governmental standards or health-based criteria identified by a toxicologist engaged by the City. City's Exhibit No. 90. Among these would be methylene chloride, trichloroethylene, tetrachloroethylene and benzene, (T. 1478) as to which "the current regulatory policy is that it is possible for as little as one molecule . . . to act as . . . a carcinogenic initiator . . . [so] that there is no real threshold." T. 1447. Maximum concentrations would exceed those Florida prescribes as primary drinking water standards for titanium threefold, for benzene fivefold, for chromium more than fivefold, for sodium approximately 16-fold, for manganese 68- fold, for iron 280-fold, and for methyl ethyl ketone almost 130-fold. City's Exhibit No. 90. Methylene chloride would occur in the leachate in concentrations 39 times greater than the "USEPA proposed Preliminary Protective Concentration Limits." Id. Only yard trash "soils/land clearing waste, waste from landscapers" (T.956) and construction and demolition debris, "clean debris, inert materials, construction and demolition wastes that are inert, roofing materials," id., and the like, not mixed either with industrial or with regular household garbage, would be accepted for disposal in the Class III facility. Unless these materials are adulterated, they are "easy to bio-degrade . . . [or] are insoluble," (T. 1923) and rainwater percolating through them should yield a leachate with "neutral pH . . . low to moderate [biological oxygen demand] . . . [and] metals [if any] . . . below detection limits or background conditions." T.1923. But "some materials get in" (T. 2106) despite efforts to exclude them. "Demolition debris can have oiled floors and creosoted pilings as part and parcel of the structure." T. 3008. Old paint contains lead and cadmium. Debris from old houses can include rat poisons. Grass clippings "could contain small amounts of herbicides and pesticides." T.2101. In fact, "it's not unusual for yard waste to be very rich in biocides." T. 3009. Such chemicals are used in Jacksonville. When autopsies of seagulls found at the Girvin Road landfill revealed traces of diazanon, tests of water taken from "the stormwater ponds in the subdivision across the street" (T.990) showed diazanon was present there. Bioassays the DER runs on effluent from the City's Buckman wastewater treatment plant regularly report toxicity in excess of allowable limits (T.1877-8) and the EPA has "identified malathion and diazanon as the toxicants," (T. 1881) which are killing at least one species of flea in certain standard laboratory tests performed on the effluent. Leachate Leakage The composite liner would not keep all leachate generated in the Class I landfill from reaching the naturally occurring soils underneath, and eventually the groundwater under the site. Even under normal operating conditions, and even on the City's optimistic assumption that it can achieve a permeability of 1 x 10-7 centimeters per second, thousands of gallons of leachate a year would escape through flaws in the liner while the landfill was in operation. If leachate drain pipes burst or torrential rains required backing leachate up in the cells, thousands of gallons a day could leak. If two lifts of clayey sand achieve a permeability no lower than 1 x 10-5 centimeters per second, millions of gallons of leachate would enter the groundwater over the ten-year active life of the landfill, even without burst pipes or extraordinary precipitation. Once the Class I landfill attained the design height, it would be capped with impermeable materials to minimize leachate generation. As with the liner underneath, the impermeable cap would be covered with sand to facilitate drainage. Vegetation would hold the drainage soil in place. Closure plans have already been drawn, but they are subject to revision and require DER approval before implementation. If necessary, side slopes could be lined to prevent leachate seepage there. Closure would reduce, but would not end, leachate production and leakage. Virtually impermeable to water, high density polyethylene is highly permeable to certain permeants, including some that occur in landfill leachate. Leachate constituents known as "aromatic hydrocarbons" move "right on through" (T. 3017) high density polyethylene. To some extent, the montmorillonite component of the liner under the Class I area would impede these materials' movement into naturally occurring soils. The evidence did not quantify the montmorillonite's efficacy in this regard, but the City's expert's testimony that leakage of this kind would be "insignificant" (T. 830) went unrebutted. Permeation aside, the rate at which leachate leaks depends on the nature, number and size of flaws in the synthetic liner, the height and duration of the leachate head above the defects, and the transmissivity of what is underneath. Here transmissivity turns both on the hydraulic conductivity of the clayey sand in the vicinity and on the extent of air spaces between the clayey sand and the overlying high density polyethylene. Sand grains cause microscopic spaces, while imperfections in the montmorillonite layer and wrinkling of the polyethylene cause larger spaces. Leachate leaking into a space between the geomembrane and the soil spreads over a larger area before penetrating the clayey soil, in correspondingly larger volumes. Calculations predicated on the transmissivity characteristics of the geonet and the sand layer above it demonstrate a theoretical leachate flow over the liner so rapid that leachate would never accumulate on the geomembrane to a depth of as much as a tenth of an inch. But these calculations assume no ponding behind wrinkles in the synthetic liner, or any other impediment to the flow of leachate. Especially since holes in liners are likely to occur near wrinkles (because stresses are greater there) a more realistic assumption, for calculating leachate leakage rates, is a head of one inch, "the smallest practical hydraulic head you can achieve." T. 2994. On the twelfth day of hearing, when St. Johns County's liner expert testified that a six-inch layer of the montmorillonite might result in permeability as high as 5 x 10-4 centimeters per second, the City had not yet amended its application to increase the thickness of the clayey sand layer from six inches to twelve. The City's proposal now calls for two lifts of a 20 percent clayey sand with a saturated hydraulic conductivity in situ of 1 x 10-7 centimeters per second. This can be achieved, if at all, only with material that laboratory tests indicate has hydraulic conductivity of 1 x 10-9 centimeters per second or less. "[I]f you put down clay that the lab says has a permeability of 10 to the minus 7 centimeters per second, . . . when you put it down in the field you get from one to two orders of magnitude greater permeability than that. . . . related to how thick it is." T. 2988. Even a three-foot liner comprised of six lifts ends up with conductivity ten times greater than the same material under laboratory conditions. Mr. Deans, who designed the liner for the City, testified that a permeability of 1 x 10-7 centimeters per second was "readily achievable" even with six inches of clayey sand, but he had never designed a liner before, and his testimony in this regard has not been credited. To judge from its eleventh- hour amendment, the City did not believe it, either. Only two lifts are to comprise the clayey sand layer. No study of a clayey sand layer as thin as 12 inches has found hydraulic conductivity of less than 1 x 10-5 centimeters per second. Three lifts are necessary to create an effective barrier. "[Y]ou need at least three lifts to get the middle one hopefully working right." T. 2987. "[E]ngineers believe that the bottom layer gets fouled, the top layer cracks and has problems. Your best chance is the in between layers. You need at least three layers, and they would rather have four to be reasonable, and EPA says six." Id. Studies of twelve-inch liners put down in two lifts ("[t]he thinnest one we found anybody had ever studied" T. 2980) showed them to be "inadequate." T. 2987. With an inch of head, assuming defects with an average area of 1 x 10-5 square meters, an assumption with which all the experts seemed comfortable (the City's expert assumed larger holes), the published EPA formula yields a per defect leakage rate of 6.7598 x 10-11 cubic meters per second, assuming hydraulic conductivity for the montmorillonite layer of 1 x 10-7 centimeters per second. But plans to use only two lifts to form a 12-inch layer do not give reasonable assurance of vertical hydraulic conductivity that low. Mr. Coram's testimony to the contrary, expressly predicated on reports of laboratory tests on samples, did not address the evidence that laboratory tests do not tell the whole story, in the case of a thin layer of clayey sand compromised not only by inherent imperfections, but also by highly permeable subgrade soils, kneaded into it by the sheepsfoot. Because "clods are broken down in the laboratory and stones and cobbles are screened from the sample . . . the effects of both are not accounted for in permeability tests on laboratory compacted samples." City's Exhibit No. 190. Substituting a hydraulic conductivity of 1 x 10-5 centimeters per second, the EPA formula yields a leakage rate between 57 and 58 times greater: 3.8898 x 10-9 cubic meters per second. Although the EPA's most recently published leak rate formula makes no allowance for less than an ideal fit between the components of a composite liner, City's Exhibit No. 190, the author of the EPA formula, who testified for St. Johns County, subscribed to modifications to the formula developed to take this factor into account. DER's Exhibit No. 35. The montmorillonite layer's hydraulic conductivity is an unrealistically low measure of the transmissivity of the medium underneath the polyethylene. Using it for this purpose, without adjustment, ignores inevitable, intervening air spaces. Perfect contact between a synthetic liner and the soil it overlies cannot be accomplished, even in a laboratory setting. On a project of the kind proposed, contact would range from good, where the relatively larger size of sand grains in the clayey mix creates air spaces, to poor, where wrinkles (left in to avoid the weakening effects of stretching the material) cause much larger air spaces. No expert found fault with the more recent formulae (Bonaparte/Giroud) set out in DER's Exhibit No. 35, and none quarreled with the proposition that the published EPA formula made unrealistic assumptions about the contact between polyethylene and clayey sand. The Bonaparte/Giroud formula that assumes good contact yields a leakage rate of 1.6090 x 10-8 cubic meters per second per defect, a little more than four times what the EPA formula predicts for an ideal fit, assuming an inch of head and vertical hydraulic conductivity for montmorillonite in situ of 1 x 10-5 centimeters per second. Assuming poor contact, without varying any other assumptions, yields a leakage rate approximately 5.5 times greater: 8.8115 x 10-8 cubic meters per second. In its proposed recommended order, at page 35, DER accepts, at least for purposes of argument, the proposition that contact between soil and geomembrane would be poor in places, and calculates a leachate leakage rate of 5.45 x 10-3 gallons per day (2.3887 x 10-10 cubic meters per second per defect.) But this assumes that "the permeability of the City's clay liner will be 1 x 10- 7 cm per second and the maximum head over liner will be 0.062 inches." The evidence showed that the maximum head could not be kept below one inch, and did not give reasonable assurances that two lifts would result in vertical hydraulic conductivity of 1 x 10-7 centimeters per second for the clayey layer. Substituting an inch for .062 inches gives a rate of 2.9177 x 10-9 cubic meters per second. Substituting 1 x 10-6 for 1 x 10-7 and an inch for 0.062 inches, the leakage rate becomes 1.6034 x 10-8 cubic meters per second. Groundwater Contamination Uncontroverted expert opinion put the flow of groundwater under the Class I disposal area at 0.063 cubic feet or 0.47 gallons per day (2.0592 x 10-8 cubic meters per second) through a hypothetical square or cube one foot on a side. Except under unusual conditions, leachate leaking from the Class I facility would, before entering the groundwater, pass through approximately a foot of fill dirt or naturally occurring soils, which consist in large part (92 to 99 percent) of relatively inert, quartz sand. The presence of organic materials, however small the quantities, raises the prospect of adsorption and other chemical reactions, before steady state is attained. Physically, the soil would disperse the leachate, diminishing concentrations of leachate constituents entering groundwater. After such attenuation as the soil afforded, leachate would enter the groundwater, which would dilute and further disperse it, although not nearly as dramatically as the City's toxicologist testified. This witness assumed uniform mixing, rather than the discrete plume which persons with greater expertise in groundwater contamination convincingly predicted. By using the rate of "groundwater flow beneath a defect and the rate of leakage through that defect . . . [he] c[a]me up with a volume to volume dilution factor to identify a concentration in the groundwater." T. 1214. Because Dr. Jones took an unrealistically low leakage rate as a starting point, he predicted an unrealistically low concentration of one part leachate to 4,400 parts groundwater, inside a cubic foot immediately below each leak. Concentrations vary directly with the leakage rate per defect. T. 1224. The formula that assumes good, but not ideal, contact between liner components yields a leakage rate per defect of 1.609 x 10-8 cubic meters per second, if the layer of clayey sand has hydraulic conductivity of 1 x 10-5 centimeters per second. Substituting this leakage rate, the City witness' methodology yields a dilution ratio of 2.0592 parts groundwater to 1.609 parts leachate, or 1.2798:1, more than a hundred times less than the 130:1 dilution ratio that the City concedes is the minimum it must prove, at the edge of the zone of discharge. See Respondent City of Jacksonville's Motion to Strike St. Johns County's Memorandum Concerning Leachate Rates, p. 5. Substituting the coefficient for poor contact, the ratio in the hypothetical cube under the landfill becomes a paltry 2.0592 parts groundwater to 8.8115 parts leachate or .2337:1. Using Dr. Jones' methodology, a leakage rate of 1.6034 x 10-8 cubic meters per second per defect would result in leachate concentrations in groundwater of one part leachate to 1.2483 parts groundwater. Substituting a rate of 2.9177 x 10-9 cubic meters per second per defect yields a ratio of 2.0592 parts groundwater to .29177 parts leachate, or one part leachate to 7.0576 parts ground water. Even if the contact between geomembrane and montmorillonite were uniformly good and the clayey sand layer had a permeability of 1 x 10-7 centimeters per second at every point, a dilution ratio of only 37.4444:1 would result. In 132 acres of high density polyethylene, the evidence showed that 660 flaws could reasonably be anticipated, and that 132 flaws were absolutely unavoidable. Methylene chloride would end up in the groundwater in proscribed, carcinogenic concentrations as far away as 20 feet from many leaks within 90 days. Under some leaks, perhaps all, benzene, a proven human carcinogen, would also occur in prohibited concentrations. As leachate plumes dispersed, concentrations would diminish, eventually to levels at which they pose "potentially acceptable" (T. 1475) risks even in the case of "a 70-year water consumption of two liters of water per day by a 70-kilogram adult." T. 1217. No evidence suggested that they would remain in concentrations above these levels by the time they reached the edge of the zone of discharge. City's Exhibit No. 193, which uses a leakage rate much lower than the range of leakage rates likely to occur, if the landfill is built, predicts concentrations of various leachate constituents at the edge of the zone of discharge, assuming a leak at the edge of the disposal area. Multiplying predicted concentrations by quotients, obtained dividing likely leakage rates by the assumed rate, suggests carcinogenic leachate constituents would not occur in prohibited concentrations at the edge of the zone of discharge. But extrapolating in this fashion also suggests that violations may occur outside the zone of discharge, absent attenuation in the vadose zone, in the event of a leak at the edge of the Class I disposal area, for iron, manganese and methyl ethyl ketone. Groundwater Monitoring The City proposes to place monitoring wells at intervals of 250 to 500 feet around the Class I and Class III disposal sites. Some 25 shallow monitoring wells would be located 50 to 100 feet from the deposition areas, within the zone of discharge. In addition, seven clusters, each consisting of three wells screened at different depths, would punctuate the boundary of the zone of discharge. A cluster of wells upgradient would make it possible to monitor background conditions. With two-inch diameters and ten-foot screens, each well would receive a flow of less than a gallon a day. The contaminant plume from the Class III landfill would be large enough to be detected readily in samples drawn from a number of wells. But there was testimony that the plume, even from a 10-foot wide leak at the edge of the Class I disposal area, could pass between two wells 500 feet apart, undetected. Rather than a single large leak, moreover, the experts predict hundreds of small leaks in the Class I disposal area liner. The assumption is that flaws in the geomembrane would have an area of only one tenth of a square centimeter, on average. Any one of the plumes emanating from such a leak could easily pass undetected through a 500-foot gap between monitoring wells. The monitoring plan apparently relies on the great number of leaks expected. But even if samples from a monitoring well revealed a leak, the magnitude of hundreds of other leaks would not be disclosed. Well Contrived After the City filed its application for a permit to construct a landfill, but before DER had issued its notice of intent to grant the application, four wells were put in on the McCormick property, within three feet of the southern boundary of the City's property, and within 205 feet of the proposed Class III disposal area. The wells are more than 500 feet from the lined, Class I disposal area. Spaced at 1,000-foot intervals, within a 125- foot-wide utility easement in favor of the City of Jacksonville Beach, three of the wells are 25 feet deep and one is 28 feet deep. McCormicks' Exhibit No. 7. Each consists of a length of PVC pipe, 1 1/4" in diameter, leading to a red pitcher pump mounted on a wooden platform supported by four fence posts. City's Exhibit No. 194. Pumps of this kind must "periodically be pumped and primed or they have to periodically be taken apart and have the internal seals and leather valves replaced." T.2005. On April 7, 1988, the St. Johns River Water Management District issued a warning notice to "Haden McCormick" alleging that the wells had not been grouted, had been dug without necessary permits, and had not been the subject of required well completion reports. The next day, the St. Johns County Environmental Protection Board, apparently in response to applications inspired by the warning notice, issued a permit for each well designating the "usage" of each as irrigation. McCormicks' Exhibit No. 7. Well completion reports dated April 14, 1988, reported that the wells had been grouted. McCormicks' Exhibit No. 3. Asked the purpose of the wells in a deposition on April 25, 1988, J. T. McCormick said, "We need to monitor what [the landfill is] doing . . . [W]e need to . . . prepare ourselves for having people live in this area, to occupy it, to monitor it." T. 2227-8 A week earlier J. C. Williamson, Jr. had requested on behalf of B.B. McCormick and Sons, Inc. that the St. Johns County Environmental Protection Board amend the permits to show well usage as "Private Potable" instead of "Irrigation". This request was granted on April 27, 1988. McCormicks' Exhibit No. 2. On May 2, 1988, St. Johns River Water Management District's chief hydrologist wrote a lawyer for the McCormicks that "the completion reports submitted by a licensed driller, and the St. Johns County permits fulfill the requirements of the District." McCormicks' Exhibit No. 1. Analysis of samples of water taken from the wells on February 27 and 28, 1989, revealed total coliform levels acceptable for private wells. John Haydon McCormick explained the decision to put the wells in: [D]uring that week the City had filed their application with the DER which, in a sense, fixed their design . . . and when we became aware that this Class III landfill was as close as it is to our border, we became concerned about the future use of potable drinking water, and after consulting with counsel we were informed that we could legally install wells along that border. T. 2242. No owner of the property where the wells are located lives on the property nor, as far as the record shows, has an owner or anybody who does live on the property ever drunk water from the wells. About a half mile from the City's property are two other wells near a house on the McCormick property. When an owner's son drank water from one or more of the wells, as recently as the fall of 1988, he had to take water to the site with him in order to do it. The hand pumps require priming and nobody has bothered to store water near them for that purpose. On February 26, 1989, when the City's expert arrived for "splitting samples to submit to different laboratories," (T.1007) The "pumps were in a 20-gallon washtub in the back of . . . one of Mr. McCormick's employee's trucks. They were all removed from the well heads . . . [apparently] being soaked to generally recondition the seals in the pumps and to sanitize the pumps." T.2008 Two "of the old leather seals from the pumps [were] on the ground." T.2009. Within the shallow aquifer, groundwater flows from the wells northerly underneath the proposed Class III disposal area in the direction of Durbin Swamp. Use of the four existing wells "would in no way modify the groundwater flow system." T. 2045. But a well or wells could be so constructed on the McCormick property that continuously pumping from them would reverse some of the groundwater flow under the proposed Class III disposal area, to the extent that water flowing from beneath the Class III disposal area could be drawn from one of the existing wells along the McCormick boundary. T. 2075-80. Nor would consumptive use permits be necessary to dig wells which could cause such a change in groundwater flows. T. 2075. When the City discovered the wells abutting the southern boundary of its property, it did not direct its engineers to alter the design of the landfill to preclude solid waste disposal within 500 feet of the wells. The total project cost, excluding legal fees, is estimated in the neighborhood of $46,000,000. Redrawing the plans now to reduce the size of the Class III disposal area, without altering the size of the Class I disposal area, would take two to three months, and cost approximately $100,000. This approach would require reducing the capacity of the Class III area from 4.1 million cubic yards to 2.5 million cubic yards and, unless construction debris, which can be disposed of without a DER permit, were diverted elsewhere, its useful life from about ten years to about six years. Tipping fees would have to be higher "to recover the capital fixed costs over fewer tons." (T. 2208) Increased design costs alone would require recouping an additional 4 cents per cubic yard (more considering the time value of money) from tipping fees for Class III debris. Operations would be less efficient and presumably more expensive. T. 2207. Alternatively, the entire facility could be redesigned to achieve the same capacity and useful life as now contemplated. Such a redesign would require four to six months' work and cost approximately $250,000. Recovering this cost through increased tipping fees for Class III wastes would add slightly more than 6 cents a cubic yard (again ignoring the time value of money.) Alternative sites for disposal of Class III waste are available to the City. Indeed the site for which the City now seeks a permit was not even among the ten sites originally considered for the project. T. 2224-5. Decreased transportation costs to another site closer to the source of such waste might more than offset increased tipping fees. But separate facilities could create other problems. Ms. Nogas explained: From an operations standpoint . . .If I run out of Class III area and . . . site a separate Class III area somewhere else, if I had a truck coming to that facility and he really should have been in a Class I area, and I say "No, go out the gate and go five miles down the road . . .[to the] Class I facility," . . . I have a much better chance of . . . him never showing up at my Class I facility. T 2208-9. On the other hand, when asked about placing a Class III facility elsewhere in Duval County, Ms. Nogas, reiterating an earlier statement, testified, "[I]f that were what we had to go to, I would have no operational problems with it." T. 221. Mr. Wells' testimony that there "are 16,000 acres of less environmentally flawed acres seven to 12 miles from the generating centroid accessible from four-lane roads and not near residential or commercial properties," (T. 1248) and that the proposed site "is the furtherest site from the generating centroid, 21 and three-quarters miles to the dump site, and will cost taxpayers an extra $3 million to $5 million a year in longer haul time" (T. 1247) was received on the issue of the decisionmakers' credibility only.
Recommendation It is, accordingly, RECOMMENDED: That DER deny the City's request for variance. That DER deny the City's application for a permit to construct a landfill. That DER deny the City's application for a dredge and fill permit. That DER grant the City's application for a permit for management and storage of surface waters, on conditions proposed in the intent to issue, unless modified by agreement of all parties. DONE AND ENTERED this 16th day of October, 1989, in Tallahassee, Leon County, Florida. Robert T. Benton, II Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the division of Administrative Hearings this 16th day of October, 1989. APPENDIX A Petitioner St. Johns County's proposed findings of fact Nos. 1-4, 6, 10-12, 14, 16, 18, 21,23, 24-28, 33, 35, 37, 38, 41-45, 47-48, the first sentence of No. 51, Nos. 52-56, 57 except for the first sentence, which is rejected, 58, 59, 62, 64, 66, 68-74, 95-103, 106-109, 111- 116, 118, 131, 132, 133 except for subpart 7, 134, 136 and 137 have been adopted, in substance, insofar as material. With respect to petitioner St. Johns County's proposed finding of fact No. 5, and the second sentence of petitioner St. Johns County's proposed finding of fact No. 51, the design rate is not the same as the current rate of deposition. Petitioner St. Johns County's proposed findings of fact Nos. 7, 8, 9, 13, 15, 17, 22, 75, 110 and 138 relate to subordinate matters. Petitioner St. Johns County's proposed finding of fact No. 19 accurately recites the testimony. Petitioner St. Johns County's proposed finding of fact No. 20 is immaterial. With respect to petitioner St. Johns County's proposed finding of fact No. 29, the City's evidence that leakage of this kind was insignificant went unrebutted. Petitioner St. Johns County's proposed findings of fact Nos. 32 and 120-123 are immaterial to the present application. With respect to petitioner St. Johns County's proposed finding of fact No. 30, the City's estimates were unreasonably low. With respect to petitioner St. Johns County's proposed finding of fact No. 31, the evidence showed that nine gallons a day was at the upper limit, not that it would actually occur. With respect to petitioner St. Johns County's proposed finding of fact No. 34, at least 13 substances occur in concentrations that exceed health-based standards. Petitioner St. Johns County's proposed findings of fact Nos. 36 and 63, 117, 119 and 135 are proposed conclusions of law. With respect to petitioner St. Johns County's proposed finding of fact No. 39, the probability of a leak on the edge of the disposal area was not established. With respect to petitioner St. Johns County's proposed finding of fact No. 40, the evidence did not show that when "two or more toxic substances are combined" they necessarily have synergistic impacts. With respect to petitioner St. Johns County's proposed finding of fact No. 46, the City's assumption of no attenuation was an appropriately conservative approach that is not inconsistent with the City's unrefuted testimony that attenuation would occur. With respect to petitioner St. Johns County's proposed finding of fact No. 49, the evidence did not prove that the City would allow four feet of leachate to stand on the liner. Petitioner St. Johns County's proposed findings of fact Nos. 50 and 60 immaterial to the present application. With respect to petitioner St. Johns County's proposed finding of fact No. 61, the evidence did not establish the contentions following the clause ending "and into Durbin Creek,". With respect to petitioner St. Johns County's proposed findings of fact Nos. 65 and 67, the McCormick wells have served ornamental and talismanic purposes, but they were not shown to be potable water supply wells, within the meaning of the rule. At the time of hearing the pumps did not function and were not mounted on the wells. Petitioner St. Johns County's proposed finding of fact No. 76 has been adopted, in substance, insofar as material, except that there was at least one effort to collect toxic wastes in Jacksonville. With respect to petitioner St. Johns County's proposed findings of fact Nos. 77 through 94, proposed permit conditions are not proposed findings of fact. With respect to petitioner St. Johns County's proposed finding of fact No. 124, the evidence was clear that more wetlands were to be destroyed than were to be created. Petitioner St. Johns County's proposed finding of fact No. 125 is rejected as against the weight of the evidence. With respect to petitioner St. Johns County's proposed findings of fact Nos. 126, 127 and 128, mitigation , particularly as regards the wood stork, if the landfill is built. Petitioner St. Johns County's proposed finding of fact No. 129, Durbin Creek enters Julington Creek, shortly before the latter reaches the river. Findings of fact proposed by petitioners J.T. McCormick and the Estate of Benjamin R. McCormick (McCormicks) Nos. 1-4, 6-10, 13, 15-17, 20, 21 and 23 have been adopted, in substance, insofar as material. With respect to McCormicks' proposed finding of fact No. 5, a preponderance of the credible evidence did not establish that the wells would be used to supply potable water in the future, even if the pumps are repaired to make it possible. Nor did the evidence establish any such authentic, "non-forensic," use in the past. With respect to McCormicks' proposed finding of fact No. 11, evidence was adduced that other sites had been considered by engineers the City engaged. T. 2224-5. With respect to McCormicks' proposed finding of fact No. 12, testimony put the delay at two to three months. T. 2139. The City could have avoided this delay. McCormicks' proposed finding of fact No. 14 has been adopted, in substance, insofar as material, except that the proportion of the Class III waste stream construction and demolition debris comprises is not stated at T. 2149. With respect to McCormicks' proposed findings of fact Nos. 18 and 19, the four and six cents per ton computations ignore the time value of money, among other things. McCormicks' proposed finding of fact No. 22 is immaterial. McCormicks' proposed finding of fact No. 24 is properly a proposed conclusion of law. Findings of fact proposed by Florida Wildlife Federation, Inc., St. Johns County Audubon Society, Sierra Club, Inc., Coastal Environmental Society and River Systems Preservation, Inc. came in two unnumbered installments. Findings of fact have addressed the substance of each. Without numbering, it is difficult to treat the material. Petitioner STOP's proposed findings of fact Nos. 5-7, 9-10, 12-18, 20, 22- 24, 26-27, 29, 32-47, 49, 50, 52, 55-57, 59-60, 62, 63, 66, 67, 69, 70, 72 and 73 have been adopted, in substance, insofar as material. Petitioner STOP's proposed findings of fact Nos. 1-4, 30, 31, 65, 71, 75 and 76 are properly proposed conclusions of law in part and relate otherwise to DER's preliminary analysis, which is technically immaterial. With respect to petitioner STOP's proposed findings of fact Nos. 8 and 58, Mr. Kappes said he had seen alligator on site but, when asked for specifics, testified to tracks they had left in the southeast corner of the site. Equally ambiguously, the City stated in its draft application that alligator had been "noted" on the property. The evidence did not show that ospreys are protected or listed in Duval County. Petitioner STOP's proposed findings of fact Nos. 11 and 74 relate to subordinate matters. With respect to petitioner STOP's proposed finding of fact No. 19, the inference that all commensals is present is problematic here, since the gopher tortoises were relocated by man from a site many miles away. With respect to petitioner STOP's proposed finding of fact No. 21, 80 to 82 of 105.7 acres of gopher tortoise habitat would be destroyed. Petitioner STOP's proposed finding of fact No. 25 is immaterial to this application. With respect to petitioner STOP's proposed finding of fact No. 28, Mr. Wiley so testified. With respect to petitioner STOP's proposed findings of fact Nos. 48, 51 and 64, although the conservation easement on uplands would not result in additional habitat, it would preclude further diminution. With respect to petitioner STOP's proposed findings of fact Nos. 53 and 54, no eagles are currently nesting on site, and Eagle Nest Island, where eagles nested until 1983, is off site. With respect to petitioner STOP's proposed finding of fact No. 61, the evidence did not establish that Mr. Kappes saw the red-cockaded woodpecker on site, even though he found six active nests within three miles of the site. With respect to petitioner STOP's proposed finding of fact No. 68, Dr. White so testified. DER's proposed findings of fact Nos. 1-9, 11-15, 17, 24, 26, 33, 37, 39, 41-45, the first three sentences of No. 50, Nos. 52-56, 62-64, 66, 67, except as regards inherent legislative facts, 70-87, 89-92 and 95 have been adopted, in substance, insofar as material. With respect to DER's proposed finding of fact No. 10, 0.9 acres of wetlands contiguous to Durbin Swamp and within the jurisdiction of the St. Johns River Water Management District would be used for a storm water retention basin. DER's proposed findings of fact Nos. 18 and 20 have been adopted, in substance, except that these steps do not ensure or guarantee a quick return of water quality functions. DER's proposed findings of fact Nos. 21, 32, 35, the last sentence of No. 50, Nos. 51, 88 have been rejected as against the weight of evidence. With respect to DER's proposed findings of fact Nos. 22 and 28, mitigation areas with deep ponds in the middle will permit fish to avoid the conditions under which wood storks feed. With respect to DER's proposed finding of fact No. 23, the steep sided ponds, sparser canopies and lesser extent of created isolated wetlands offset their "higher quality." With respect to DER's proposed finding of fact No. 25, the mitigation proposed does not amount to a one to one ratio. While significant, the easements preserve the status quo and do not compensate for lost wetland functions. With respect to DER's proposed finding of fact No. 27, the evidence suggested no reason why bears would not forage in isolated, as well as contiguous wetlands. With respect to DER's proposed finding of fact No. 29, to the extent possible, existing trees would be transplanted; if they all survived, the number of perches would be undiminished, except for branches broken in the process. With respect to DER's proposed finding of fact No. 30, sightings nearby and habitat on site amount to evidence of use of the site. As regards the indigo snake, testimony that these animals were introduced to the site was uncontroverted. With respect to DER's proposed finding of fact No. 31, alligator tracks were found in the southeastern part of the site. With respect to DER's proposed finding of fact No. 34, no southeastern kestrel nests were found on site. With respect to DER's proposed finding of fact No. 36, it is not in the public interest to issue a permit for a lined landfill that would cause pollution in violation of DER's water quality standards. If a landfill were properly permitted, it would be in the public interest to have access. With respect to DER's proposed finding of fact No. 38, the first sentence (which seems to contradict the fourth) has been adopted, in substance, insofar as material. With respect to DER's proposed finding of fact No. 40, there was no evidence of cumulative impacts to Durbin Swamp, as opposed to Durbin and Julington Creeks. With respect to DER's proposed findings of fact Nos. 46-48, the clayey sand, placed in two six-inch lifts, would have much greater permeability as a unit than samples of the same material screened for certain imperfections and tested in the laboratory. In the field, it would not be possible to remove all clods and other materials that make for greater vertical hydraulic conductivity of the unit. Subgrade mixing would occur, in putting down the first of the two lifts. A 12-inch layer would be many more times transmissive than a liner of the same material put down in six six-inch lifts to attain the three feet DER requires, when no synthetic liner is used. Mr. Fluet did not testify that a 12-inch layer would achieve a permeability of 1 x 10-7 centimeters per second. He testified that nobody who had studied 12-inch layers had reported permeability of less than 1 x 10-5 centimeters per second for a clayey layer of that thickness. With respect to DER's proposed finding of fact No. 49, the geomembrane is subject to the effects of pressure and temperature variation would contribute to wrinkling. With respect to DER's proposed finding of fact No. 57, leachate leakage would diminish after closure, but would not stop altogether. With respect to DER's proposed findings of fact Nos. 59 and 60, the working hypothesis is that even a single molecule of certain leachate constituents may initiate cancer, although concentrations below the levels identified are said to pose no more than an acceptable risk of doing so. DER's proposed finding of fact No. 61 describes the methodology correctly, but the particular results have not been accepted. With respect to DER's proposed finding of fact No. 65, predicted concentrations depend on the leakage rate assumed. With respect to DER's proposed finding of fact No. 68, data showing the composition of discharges to ground water from other Class III landfills were not presented. Supposed "legislative facts" do not constitute evidence. With respect to DER's proposed finding of fact No. 69, the evidence did not show what concentrations of biocides or other chemical constituents were likely to be. With respect to DER's proposed finding of fact No. 93, the phrase "monitoring well" was not used. With respect to DER's proposed finding of fact No. 94, wells Nos. 21 and 22 were between 25 and 35 feet deep. Haydon McCormick testified that a shallow well near the house was for potable water supply. DER's proposed finding of fact No. 96, has been adopted, in substance, except that additional time might not be required for permitting. With respect to DER's proposed findings of fact Nos. 97 and 99, balancing of social and economic interests is appropriate only if hardship is proven, and immaterial otherwise. The City's proposed findings of fact Nos. 1-9, 16-18, 20-25, 30, 33, 35-38, 42, 44, 46, 49, 50, the first two sentences of No. 55, Nos. 58-62, 65, 73, 74, except for the last sentence, Nos. 75, 77-83, 88-92, 94-100, 104, 107, 108 and 110 have been adopted, in substance, insofar as material. With respect to the City's proposed finding of fact No. 10, despite timbering of the uplands the site was characterized as "relatively unaltered." With respect to the City's proposed finding of fact No. 11, no decline in water levels was shown to be irreversible. With respect to the City's proposed finding of fact No. 12, the study was of "trivial value." With respect to the City's proposed finding of fact No. 13, bald eagles and wood storks do make use of the site and indigo snake(s) were set loose there. With respect to the City's proposed finding of fact No. 14, a witness testified to his "confidence" (T.2918) that the kestrel he spotted was a Southeastern kestrel. Signs of alligator were found near the southeast corner of the property. With respect to the City's proposed finding of fact No. 15, hunting was mentioned. The City's proposed findings of fact Nos. 19, 54, 56 and 84 pertain to subordinate matters. With respect to the City's proposed finding of fact No. 26, the witness so testified. With respect to the City's proposed finding of fact No. 27, it was not proven that noise would be "minimized." With respect to the City's proposed finding of fact No. 28, bears could move through the culvert, but elsewhere the access road (particularly during the day), fences and human activity on site would indeed "impede black bear movement in the area." The City's proposed findings of fact Nos. 29, 48, the last sentence of 55, Nos. 57, 71, 72, 85, 87 and the last sentence of 101 have been rejected as being against the weight of the evidence or as unsupported by the preponderance of evidence. With respect to the City's proposed finding of fact No. 31, mobility will not assure successful relocation if existing populations are fully utilizing habitat in the vicinity. The City's proposed findings of fact Nos. 32, 86 and 93 are properly proposed conclusions of law. With respect to the City's proposed finding of fact No. 34, groundwater was shown unlikely to reach solid waste on site. With respect to the City's proposed finding of fact No. 40, the maximum head would not be less than one inch. With respect to the City's proposed finding of fact No. 41, such sand might not be available on site. With respect to the City's proposed finding of fact No. 43, some leachate would leak through the liner. With respect to the City's proposed finding of fact No. 45, some rainwater would infiltrate. With respect to the City's proposed finding of fact No. 47, the evidence did not show that the clayey sand layer would attain so low a vertical hydraulic conductivity. If these liners have performed well, it has not been without leakage, both through flaws and by permeation. With respect to the City's proposed finding of fact No. 51, the subgrade would be inspected, in an effort to assure complete removal of sharp objects. With respect to the City's proposed findings of fact Nos. 52 and 53, permeability is specific to the permeant. The values quoted are for water. High density polyethylene is highly permeable to aromatic hydrocarbons. That liners leak is not speculation. With respect to the City's proposed finding of fact No. 63, the design engineer envisioned circumstances that would require backing leachate up in the landfill. With respect to the City's proposed finding of fact No. 64, violations were proven, in the absence of sufficient attenuation in the vadose zone, and attenuation there was not quantified. With respect to the City's proposed findings of fact Nos. 66 and 67, these evaluations assumed unrealistically low leachate leakage rates. With respect to the City's proposed finding of fact No. 68, this elaborate house of cards bears little relationship to the language of the free from rule. But this approach, too, shows violations, if realistic leakage rates are used. With respect to the City's proposed finding of fact No. 69, credible and credited evidence of dramatically higher leachate leakage rates than they assumed contradicted their conclusions. With respect to the City's proposed finding of fact No. 70, the witness so testified. With respect to the City's proposed finding of fact No. 76, the precise constituents of the Class III leachate were not proven. With respect to the City's proposed finding of fact No. 102, the witness so testified. With respect to the City's proposed finding of fact No. 103, the well that Haydon McCormick jetted in was 25 to 35 feet deep. With respect to the City's proposed findings of fact Nos. 105 and 106, wells could be placed so that enough water drawn from them would reverse the gradient and cause pollutants to move toward the McCormick property. With respect to the City's proposed finding of fact No. 109, the evidence about the effect on operations was ambiguous. With respect to the City's proposed finding of fact No. 111, it is unlikely that the McCormicks would take steps to reverse the flow of groundwater. APPENDIX B Three methods of calculating per defect leachate leakage rates (in cubic meters per second) were proven at hearing, each expressed as an equation or formula requiring values for three variables, for their solution, viz.: h = height of leachate head over defect (in meters) a = area of defect (in square meters) Ks = permeability (vertical hydraulic conductivity) of clayey sand layer beneath defect (in meters per second) The method advocated by the City, published by the EPA, and shown (by the author) to reflect ideal contact between liner components, which does not obtain in practice, is: Q = (0.7) x (h) x (a0.1 x Ks0.88). The method advocated by the County, endorsed by the author of the formula EPA published, and shown to reflect good contact between liner components, shown likely to occur in places, is: Q = (0.21) x (h0.9) x (a0.1 x Ks 0.74) The method advocated by the County, endorsed by the author of the formula EPA published, and shown to reflect poor contact between liner components, shown likely to occur in places, is: Q = (1.15) x (h0.9) x (a0.1 x Ks 0.74) In each case, Q represents the flow of leachate through each defect.
