The Issue Whether the costs incurred by the Department of Environmental Protection, Bureau of Emergency Response (Department) in connection with its response to Incident Number 95-SE-0248 may be recovered from Petitioners pursuant to Chapters 376 and 403, Florida Statutes.
Findings Of Fact The Department is a state regulatory agency charged with the responsibility of administering and enforcing the provisions of Chapters 376 and 403, Florida Statutes. Spill Response, Inc. (Spill Response) is a corporation which was formed in approximately 1986 or 1987, and is presently inactive and without any assets. At all times material to the instant case, George Gordon has been the sole owner, president and director of Spill Response, and, as such, has directed the operations of the corporation. Spill Response was previously in the oil spill response business, as its name suggests. At such time, it had an office in Port Everglades and stored its equipment on fenced and gated property located at 3211 Southwest 50th Avenue, Davie, Florida, on which approximately a dozen large aboveground petroleum storage tanks (surrounded by concrete containment areas) also were situated. At all times material to the instant case, the property located at 3211 Southwest 50th Avenue, Davie, Florida (FPR site) has been owned by Florida Petroleum Reprocessors, Inc. (FPR), an inactive corporation that previously was in the waste oil recovery business. The FPR site, which is presently FPR's only asset, is the subject of a pending foreclosure action initiated by Charles Green, who, at all times material to the instant case, has held a first mortgage on the property. At all times material to the instant case, George Gordon has been the president and director of FPR, and, as such, has directed the operations of the corporation. In the latter part of 1994, the storage tanks on the FPR site were no longer in commercial use. At that time, Gordon, on behalf of FPR, hired Fred Rice to clean and maintain the site in preparation for its closure. Rice was instructed to remove the petroleum residue and sludge from the tanks and from the containment areas. Rice engaged in these petroleum and sludge-removal activities on a part-time basis until the spring of 1995, when he stopped working on the project after not having received timely payment for work he had performed. Rice placed the petroleum residue and sludge that he had removed, as well the rags and other materials that he had used in the removal process, in 55-gallon drums. He filled approximately six or seven such drums. A number of other 55-gallon drums containing petroleum residue and sludge (that some person or persons other than Rice had filled) were already on the FPR site. Rice put the six or seven drums that he had filled on a truck that was parked on the site and had “Spill Response, Inc.” and “Florida Petroleum Reprocessors, Inc.” markings on its sides. The truck was owned by Spill Response and had been on the site for some time. It had no battery and was inoperable. Rice told Gordon that he had put the drums he had filled with petroleum residue and sludge on the Spill Response truck. The next time Gordon went the FPR site, in late May of 1995, he discovered that the locks on the gates had been changed and that there were vehicles and equipment on the property that did not belong there. Gordon telephoned the Davie Police Department to complain about the unauthorized use of the FPR site. A police officer was dispatched to the site to investigate. When the officer arrived on the scene, he encountered Gordon outside one of the gates. Although the gate was locked, Gordon and the officer gained access to the site by squeezing through an opening in the gate. Upon entering the site, they looked around. Based upon what they saw, they correctly "figured out" that Certified Crane and Rigging, Inc., d/b/a Certified Equipment Management Company (Certified) was storing its crane equipment and trucks on the site. At all times material to the instant case, Certified has been owned and operated by William "Skip" Walton. Walton is an acquaintance of the aforementioned Charles Green, the holder of the first mortgage on the FPR site. Certified's telephone number was painted on the equipment and vehicles it was storing on the FPR site. The police officer called the number and spoke with Walton. Following his telephone conversation with Walton, the officer informed Gordon that Walton had indicated, during the conversation, that he was leasing the FPR site from Green. Gordon advised the officer that he did not want to press criminal charges (for trespassing) against either Certified or Walton. Gordon subsequently telephoned Green. Green told Gordon that it was true that he had leased the FPR site to Walton. Green explained to Gordon that he "needed to earn some money from the property." (It had been some time since Green had received any mortgage payments from FPR or Gordon.) Gordon contacted his attorney to discuss with her what legal action, if any, he could take to regain possession of the FPR site and be compensated for the unauthorized use of the property. Gordon's attorney advised him that he "would have recourse if [he] wished to pursu[e] the matter in court," but that it might not be cost-effective for him to do so. Gordon took no action, "in court" or otherwise, to regain possession and control of the FPR site; nor did he take any action to retake possession and control of the Spill Response truck or the filled drums that were in the truck and elsewhere on the site. Furthermore, he made no effort to make sure that the drums and their contents were stored and disposed of properly, believing that the proper storage and disposal of these items were now the responsibility of the new occupant of the site. He did not return to the FPR site for over a year. On or about June 6, 1995, the Department was notified (after its regular business hours) that the Spill Response truck had been discovered abandoned on the side of the road a few blocks from the FPR site. The following day,1 Ann Meador, an Environmental Specialist III with the Department, went to the location where the truck had been abandoned and served as the Department's on- scene coordinator. The truck was in poor condition and still inoperable. It had been brought (not driven) to the location by someone other than Gordon. The truck contained 37 sealed 55-gallon drums, which were in poor condition (but not yet leaking) and had oil residue on the outside. It could not be reliably determined exactly what was in the drums without removing them from the truck and examining and analyzing their contents. Meador made arrangements for OHM Remediation Services Corporation (OHM), with whom the Department had a contract to perform such services on an emergency basis, to assist in the removal of the drums from the truck. OHM personnel (with "Level B" protective clothing and equipment) responded to the scene and removed all 37 drums from the Spill Response truck. After the drums were unsealed, their contents were examined and sampled to the extent possible2 (as were the contents of three additional drums which were filled with the "Level B" protective clothing and equipment that OHM personnel had used during the cleanup operation and then discarded). Each of the drums was assigned a number for identification purposes. To save time and money, samples from some of the drums were composited. The drums were then overpacked and taken to the Department’s hazardous waste storage facility in West Palm Beach, Florida. The Department paid OHM $7,046.93 from the Water Quality Assurance Trust Fund for the services OHM performed. In requesting OHM to perform these services and in paying OHM $7,046.93 for having done so, the Department acted reasonably and prudently. The amount it paid OHM was not excessive. The Department hired Laidlaw Environmental Services (Laidlaw) to analyze the samples that OHM had collected and to then properly dispose of the drums and their contents. Laidlaw's analysis revealed the following: drums numbered 1, 2, 3, 4, 5, 9, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 30, 34, 35, 36, 37, and 38 contained oily sludges, oil, oil mixed with water, or oily residues; drum numbered 6 contained benzene and had a flash point between 73 and 140 degrees Fahrenheit; drum numbered 29 contained benzene and lead and had a flash point of less than 73 degrees Fahrenheit; drums numbered 10 and 11 contained benzene and lead; drums numbered 7, 8, 31, 32, 33 and 39 contained benzene, lead, and cadmium. Laidlaw properly disposed of the drums based upon the results of its analysis. The Department paid Laidlaw $21,163.90 from the Water Quality Assurance Trust Fund for the services it performed. In requesting Laidlaw to perform these services and in paying Laidlaw $21,163.90 for having done so, the Department acted reasonably and prudently. The amount it paid Laidlaw was not excessive. The Department reasonably incurred other expenses (also paid from the Water Quality Assurance Trust Fund) totaling $129.82 in connection with its response to the report it had received concerning the abandonment of the Spill Response truck. The total amount the Department paid from the Water Quality Assurance Trust Fund to have the drums on the truck properly removed and disposed of was $28,340.65. It was not until Gordon received a letter from the Department advising him of the costs the Department had incurred and requesting that Spill Response and he reimburse the Department for these costs that Gordon became aware of the fact that the truck and the drums had been moved from the FPR site.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered by the Department finding that it is entitled to recover from Petitioners, pursuant to Chapters 376 and 403, Florida Statutes, the $28,340.65 in costs the Department reasonably incurred in connection with its response to Incident Number 95-SE-0248. DONE AND ENTERED this 8th day of June, 1998, in Tallahassee, Leon County, Florida. STUART M. LERNER Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 Filed with the Clerk of the Division of Administrative Hearings this 8th day of June, 1998.
The Issue The issue is whether Dr. Vigna and his corporation, AVA Hazardous Waste Removal and Disposal, Inc., should be disciplined for the improper disposal of hazardous waste.
Findings Of Fact Lyn-Rand, Inc., was a corporation in the metal fabrication and painting business in Dade County, Florida, during April and May of 1989. The industrial processes used by Lyn-Rand required the use of solvents, cutting oils, and other chemicals. Lyn-Rand employed Courtney Warrenfeltz as its quality control director. Mr. Warrenfeltz had met Dr. Anthony Vigna, who held himself out as a transporter of hazardous waste. Dr. Vigna offered to dispose of 55-gallon drums of waste which had accumulated at the Lyn-Rand facility. Dr. Vigna took samples of the waste, offered to use his federal EPA identification number in connection with the disposal, and do all the paper work involved with the disposal. Mr. Warrenfeltz believed, based upon his conversations with Dr. Vigna, that Dr. Vigna was knowledgable about hazardous waste disposal. Mr. Warrenfeltz made arrangements for Dr. Vigna to pick up nine drums of cutting oils and cleaning solvents on Saturday, April 29, 1989. Dr. Vigna was paid $500 per drum. Those drums had been marked with "x's" on the tops and sides. An employee of Lyn- Rand, Carlos Alayon, had been left instructions to expect Dr. Vigna, and had been given a check to give Dr. Vigna when the drums were picked up. While Dr. Vigna was at the Lyn-Rand site to pick the drums up, he asked Alayon for some black paint which Dr. Vigna used to paint over the labels on the drums. Alayon then helped Dr. Vigna load the drums into a rental truck. Dr. Vigna gave Mr. Alayon no paperwork, such as a manifest, receipt, or shipping papers. Mr. Warrenfeltz never received any paperwork from Mr. Alayon or from Dr. Vigna. The drums Dr. Vigna took from Lyn-Rand were discovered later, Saturday, April 29, 1989, at the business premises of Compliance Technology, Inc., a corporation located in Broward County, which is licensed to act as a broker for hazardous waste. Compliance Technology, Inc., does not, however, act as a transporter of hazardous waste. The employee of Compliance Technology who found the drums near the back loading dock, Mike Webb, was concerned, because their labels had been obliterated with black paint and the only marks on the drums were the "x's." The obliteration of the labels was a cause for concern and the bungs appeared to be leaking around the tops of two of the drums. The drums had been abandoned near a storm drain. The drums were not fenced or secured; if someone had driven into them due to their placement on the ground near the loading dock, the drums could have ruptured and the contents flowed into the storm drain and eventually into the Biscayne Aquifer. Mr. Webb notified the founder of Compliance Technology, Dr. Solon Cole, of the discovery of the drums, and the matter was reported on or about May 1, 1989, to the Broward County Environmental Quality Control Board and the City of Hollywood Police Department. Compliance Technology moved the drums away from the storm drain, barricaded them, and replaced bungs in two of the drums. On or about May 5, 1989, Dr. Cole notified Jeff Tobergte, of the Department of Environmental Regulation office in West Palm Beach, about the drums. Mr. Tobergte went to Compliance Technology the next day, and photographed the drums and sampled their contents. He found that the drums contained various solvents, including methylene chloride, ethylbenzene, toluene, xylene and phenol. The samples had a pH of less than 2 and a flash point of less than 60 degrees centigrade, and therefore were hazardous wastes. Dr. Cole and Mr. Tobergte were able to determine that one of the drums had a label which stated "Spray Iron Phosphatizer and Cleaner" "SC-283" from Novamax Tech in Atlanta, Georgia. After contacting Novamax Tech, Mr. Tobergte learned that SC-283 is an unusual product with only four buyers in Florida, three of them in Dade County, including Lyn-Rand. Mr. Tobergte then drove to all three locations in Dade County which were customers of Novamax Tech, and determined that the most likely source of the drums at Compliance Technology was Lyn-Rand. Mr. Tobergte visited Lyn-Rand on May 8, 1989, and verified that the drums he had photographed were drums which originated at Lyn-Rand. The verification was made by comparing the photographs of the drums left at Compliance Technology with drums at Lyn-Rand which still had labels. Mr. Warrenfeltz recognized the markings on the photos of the drums left at Compliance Technology. The pine needles found on the drums were also significant, since drums were stored in a manner at Lyn-Rand which lead to pine needles falling upon them. Mr. Warrenfeltz told Mr. Tobergte that Lyn-Rand had recently shipped nine drums and recognized the drums from the photographs as those delivered to Dr. Vigna. Lyn-Rand removed the drums from Compliance Technology's property and arranged for their proper disposal. Neither Dr. Anthony Vigna nor AVA Hazardous Waste Removal and Disposal, Inc., has any EPA identification number. After the discovery of the abandoned drums, Mr. Vigna mailed a letter to Compliance Technology on May 10, 1989. The letter was backdated to April 28, 1989, and states in part that it was sent to Dr. Solon Cole, the President of Compliance Technology, "to make you aware of a delivery of nine drums that my driver will be leaving off at your plant." The letter was an after-the-fact attempt by Dr. Vigna to cover himself, which is foiled by the postmark date the letter bears. The content of the letter itself, however, leaves the impression that Dr. Cole and Compliance Technology had no prior awareness of the delivery, which is consistent with the testimony of Dr. Cole, that he had not agreed to any delivery of hazardous waste by Dr. Vigna, because Compliance Technology is not a hazardous waste storage facility, or a transporter of hazardous waste. It had acted as a broker for entities needing to dispose of hazardous waste. Dr. Vigna had visited Compliance Technology, and should have known that it did not store hazardous waste. This after-the-fact letter is also inadequate to constitute a shipping manifest for the hazardous waste delivered by Dr. Vigna, for there is no designation of the source of the material, or explanation of the contents of the drums. It does not approximate the kinds of documents used by legitimate hazardous waste transporters. Perhaps most significantly, Dr. Vigna and his company never contacted Dr. Cole after the drums were dropped at the Compliance Technology site to make arrangements to pay Compliance Technology for handling the drums, as the letter of May 10, 1989, suggests. Dr. Vigna maintains that his delivery of the drums to Compliance Technology was the result of a misunderstanding he had with Dr. Solon Cole. Dr. Vigna maintained that he and Dr. Cole had discussions concerning possible business ventures and he told Dr. Cole that he would be delivering nine drums of cutting oils and cleaning solvents to Compliance Technology, Inc. This testimony is rejected as much less credible than that of Dr. Cole, and because of the rather significant problems with the letter Dr. Vigna mailed on May 10, 1989, which was designed to cover himself, not to notify Compliance Technology of a delivery before the delivery was to be made. There is some slight corroboration of Dr. Vigna's version of the facts which arises from the decision of Compliance Technology not to press criminal charges against Dr. Vigna. The lawyer for Compliance Technology, Arthur Luongo, wrote to the Assistant State Attorney on June 7, 1989, and said: I have a great concern that Compliance Technology may be liable for a malicious prosecution action should they [the employees of Compliance Technology] testify in a criminal proceeding against Mr. Vigna. I see the case as one of simple civil negligence arising out of an honest, though admittedly stupid, mistake. It is the intention of Compliance Technology to become a public corporation within a year, and being the defendant in such a suit could seriously effect the value of their stock. They do, however, intend to recover civil restitution for their time, efforts and energy in locating Mr. Vigna. At best, this letter demonstrates that Compliance Technology had its own reasons for not wanting to press any criminal proceedings, but does not show that Dr. Vigna's actions were proper. Dr. Vigna's position would have been much more persuasive if the letter sent to Compliance Technology had actually been sent near the time it was dated (April 28), or if he had made contact with Dr. Cole to discuss pricing for what Dr. Vigna contends would have been Compliance Technology's efforts in arranging for final disposal of the Lyn-Rand material. It is strange that Dr. Vigna arrived at a price to charge Lyn-Rand without knowing what his price for disposal would be from Compliance Technology. That cost to Dr. Vigna was not relevant if Dr. Vigna intended merely to dump the material. The Department's characterization of the material as abandoned by Dr. Vigna is sustained by the evidence. Dr. Vigna acted as a transporter of hazardous waste. Because the drums were rusted, two bungs had to be replaced, and were leaking, Dr. Vigna is properly regarded as having caused pollution in transporting and leaving them at Compliance Technology. The Department incurred $2,936.58 as costs and expenses in tracing the pollution back to Dr. Vigna and arranging for its proper disposal.
Recommendation It is RECOMMENDED that Dr. Vigna and AVA Hazardous Waste Removal and Disposal, Inc., be found guilty of the violations alleged in the Administrative Complaint, that a final order be entered directing them to refrain from the transportation of hazardous waste unless they first notify the Florida Department of Environmental Regulation, obtain an EPA identification number, demonstrate their financial security, and comply with all standards and procedures required by rules of the Department and applicable federal regulations; it is also RECOMMENDED that they be required, jointly and severally, to reimburse the Department $2,936.58.

Rejected for the reasons stated in Findings 10-15. Rejected, see Finding 11. It is in the nature of a manifest that it needs to be delivered with the material it is designed to accompany. A "manifest" which Dr. Vigna maintained as his own record is no manifest. Rejected because the material was left unsecured near a loading dock. Its location near the storm drain, and the obliteration of the labels lead to the conclusion that the way was it was left did constitute an imminent hazard. Rejected, see Finding 3. Rejected because the leakage from the bungs, while not severe, did present the risk of pollution through contamination of the Biscayne Aquifer if any of the contents of the nine drums had been introduced into the storm drain. Rejected, see Finding 3. COPIES FURNISHED: Agusta P. Posner, Esquire Assistant General Counsel Department of Environmental Regulation 2600 Blair Stone Road Tallahassee, Florida 32399-2400 Steven N.

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

The Issue The issue is whether Respondents should have an administrative penalty imposed, take corrective action, and pay investigative costs for allegedly maintaining a solid waste management facility without a permit and disposing of solid waste in an area subject to periodic or frequent flooding.
Findings Of Fact Based upon all of the evidence, the following findings of fact are determined: Background DDD is a corporation registered to do business in the State of Florida. Its president and sole director is William H. Stanton, Jr. The corporation is engaged in the business of "mobil recycling activities" (reduction recycling services for customers). Mr. Stanton owns a two-acre tract of property located in Section 26, Township 28S, Range 24B, on the northwest corner of Mustang Road and Longhorn Drive, Lakeland, Florida. The property is zoned for heavy industrial uses and was formerly used in some form of phosphate mining operations. The Department is the agency charged with the duty of administering and enforcing the provisions of Chapter 403, Florida Statutes, and rules promulgated thereunder. Based upon a complaint made by a Polk County Health Department employee, on October 8, 2001, a Department enforcement coordinator, Steven G. Morgan, inspected Mr. Stanton's property and observed that Respondents had filled and compacted an approximate 150 foot by 300 foot area of the site with 3 to 5 feet of "wallboard type material," which consisted of "both ground up and large pieces of wallboard." In the middle of the filled area was an additional pile of the same material around 20 to 25 feet high. Petitioner's Exhibits A, D, and E are photographs which provide an accurate representation of the site on the date of the inspection. Based on a visual inspection, but without having the benefit of his own laboratory analysis,2 Mr. Morgan concluded that the material was a solid waste made up of discarded industrial products. Under Department rules, the deposit of solid waste on such a site requires a waste facility management permit from the Department. A check of Department records indicated that Respondents do not hold a permit to operate a solid waste management facility. (DDD does hold a valid air pollution permit for grinding concrete.) During his inspection, Mr. Morgan also observed that the land adjacent to the filled area was wet, had a lower elevation than the compacted area, and contained small pockets of standing water. This was confirmed by photographs received in evidence as Petitioner's Exhibits D and E. A DDD employee who was present on the site during the inspection indicated that approximately 900 truck loads of the material had been transported to the site from Plant City after Mr. Stanton had "lost" a lease on the property on which the material had previously been placed. This was confirmed by Mr. Stanton who arrived at the site shortly after the inspection began, and who indicated that he intended to use the compacted wallboard as a sub-base (or foundation) for a wallboard recycling facility. A second site inspection by Mr. Morgan conducted on February 5, 2002, confirmed that the conditions (regarding the piles of fill material but not the standing water) at the site were unchanged from those found on October 8, 2001. On that visit, Mr. Morgan observed the site from his automobile but did not walk the property. Two other site visits were made, one on June 19, 2002, by other Department personnel. Except for a photograph (Petitioner's Exhibit C) dated June 19, 2002, which indicates the piles of material were still intact and had not been removed, the results of those inspections are not of record. Shortly after the initial inspection, the Department's Tampa District Office issued a warning letter to Mr. Stanton describing Mr. Morgan's observations and outlining the potential violations. The letter also invited Mr. Stanton to resolve the matter informally and to present a corrective action plan to mitigate the site. When the matter could not be resolved informally, the Department issued its Notice on October 10, 2002, alleging that Respondents had operated a solid waste facility without a permit and had deposited solid waste in an area prone to flooding. Even though the matter was not informally resolved, Mr. Stanton has cooperated with the Department in good faith throughout the regulatory process. The Material on the Site Invoices received in evidence reflect that the source of the deposited material was James Hardie Building Products in Plant City, Florida, and that the material was described on the invoices as "Dry Waste Material," Wet Waste Material," and "Foreign Material." James Hardie Building Products manufactures HardieBoard, which is a one-half to one-inch thick concrete formulated product used in the construction of homes and other buildings, and HardiePipe, which is used in road and bridge construction, culverts, storm sewers, and concrete pipes. The material being deposited was material used in the manufacture of HardieBoard. Mr. Stanton's long-range plans are to grind up, or recycle, the material (after all necessary permits, if any, are obtained) and then sell it to other persons, including cement manufacturing plants in the area, who will then use it for a variety of purposes, including subbase and base material, cement and concrete re-additive, and cement production. HardieBoard (as well as HardiePipe) is a variable mixture of Portland cement, water, fine silica sand, less than 10 percent cellulose (a non-toxic organic material commonly added to such products as ice cream, shampoo, baby diapers, and rayon clothing), and less than 10 percent of inert materials. The cellulose fibers are added to the concrete to avoid cracking and shrinkage and to reduce the weight of the product. Unlike concrete used for driveways and the like, HardiBoard does not have any large aggregate. Disposal of Solid Waste and Clean Debris Florida Administrative Code Rule 62-701.300(1)(a) prohibits the storing, processing, or disposing of solid waste except at a permitted solid waste management facility. In addition, no solid waste may be stored or disposed of "[i]n an area subject to frequent and periodic flooding unless flood protection measures are in place[,]" or "[i]n any natural or artificial body of water including ground water." Fla. Admin. Code R. 62-701.300(2)(d) and (e). These requirements form the basis for the charges in the Notice. Florida Administrative Code Rule 62-701.200(113) defines solid waste in relevant part as "discarded material, including solid, liquid, semi-solid, or contained gaseous material resulting from domestic, industrial, commercial, mining, agricultural, or governmental operations." Section 403.707(2)(f), Florida Statutes (2003), provides, however, that a permit is not required for "[t]he use of clean debris as fill material in any area." See also Fla. Admin. Code R. 62-701.220(2)(f). "Clean debris" is defined in Florida Administrative Code Rule 62-701.200(15) as: any solid waste which is virtually inert, which is not a pollution threat to ground water or surface waters, is not a fire hazard, and is likely to retain its physical and chemical structure under expected conditions of disposal or use. The term includes brick, glass, ceramics, and uncontaminated concrete including embedded pipe or steel. The term "virtually inert" is not defined by statute or rule. However, the parties agree that in order for a material to be "virtually inert," it must have no potential for leaking contaminants into the groundwater. In addition, if a deposited material releases contaminants into the groundwater thereby posing a threat to human health, it is considered a "threat to [groundwater]" within the meaning of the rule. The rule also provides that the material must not be a fire hazard. Finally, if a material decomposes over time after being used as fill, and releases contaminants into the groundwater, it is not "likely to retain its physical and chemical structure under expected conditions of disposal or use." Therefore, if a material has no potential for leaking contaminants into the groundwater, is not a threat to groundwater, is not a fire hazard, and is not likely to decompose over time, it constitutes clean debris and is exempt from the waste management facility permitting requirements. As noted above, Florida Administrative Code Rule 62- 701.200(15) identifies four materials that are considered to be clean debris: brick, glass, ceramics, and uncontaminated concrete. If a waste product is classified as uncontaminated concrete, it constitutes clean debris and may be used as fill without a permit from the Department. Further, clean debris may be deposited in an area subject to frequent or periodic flooding so long as flood protection measures are taken, or in a natural or artificial body of water so long as other appropriate permits (such as an Environmental Resource Permit) are obtained. Here, the central issue is whether the material deposited on Mr. Stanton's property is solid waste or clean debris. This issue turns on whether the material is virtually inert, is not a pollution threat to groundwater or surface waters, is not a fire hazard, and is likely to retain its physical and chemical structure under expected conditions of disposal or use. Assuming these criteria are satisfied, the material is exempt from Department permitting requirements for solid wastes. On this issue, the Department contends that the material is not virtually inert and is unlikely to retain its physical and chemical structure. Conversely, Respondents assert that the material is clean debris and falls within the category of uncontaminated concrete. Is the Deposited Material Clean Debris? In determining whether a material is virtually inert, or is a pollution threat to ground or surface waters, two extraction procedures have been sanctioned by the United States Environmental Protection Agency to assist in the measurement of the amount of contaminants that will leak from a material: the Toxicity Characteristic Leaching Procedure (TCLP) and the Synthetic Precipitation Leaching Procedure (SPLP). Under both procedures, the material being tested is ground up into small sand-size particles, mixed with an extraction fluid, and tumbled for 18 hours in a rotary agitator while the liquid solution extracts various metals that are found in the solids. The extracted liquid solution is then filtered and analyzed to determine the concentration of metals actually leached from the solids. Under state water drinking standards found in Table 1 of Florida Administrative Code Chapter 62-550, the maximum contaminant levels for chromium and barium (stated in milligrams per liter (mg/L)) are 0.1 mg/L and 2 mg/L, respectively. In reaching its conclusion that the fill material is a solid waste, the Department relied principally on certain tests of the material run by various laboratories between 1998 and 2000, which showed that the amount of chromium and barium leaking out of the product exceeded the State drinking water standards. See Petitioner's Exhibits K, L, M, and O. However, in every one of those tests, the laboratories used the TCLP, rather than the SPLC, which produced a worst case scenario. For the reasons stated below, the TCLP is not the appropriate procedure to be used for this purpose. The TCLP is the more aggressive of the two procedures, uses a much harsher solution than the SPLC, and generally leaches higher concentrations of metals. However, its principal purpose is to determine whether a material should be classified as a hazardous waste based on its leaching properties or characteristics. Using it to predict whether a material will leach into ground water is inappropriate because it will "leach things out in the laboratory that will never leach in the field." This is because it does not mimic conditions in the field and is "just not supposed to be used for this purpose." Therefore, TCLP leachate values should not be applied to drinking water standards. Conversely, the SPLC uses a less harsh solution during the preparation process, evaluates the potential for leaching metals into ground and surface waters, and is designed to provide a more realistic assessment of metal mobility under actual field conditions. In other words, the SPLC simulates what would happen if the sample were exposed to groundwater and rain to determine if under those conditions metals might leach into the water system below. Therefore, the SPLC is the more appropriate procedure to use here to determine whether the HardieBoard material will leach certain metals into the groundwater at levels that exceed State drinking water standards. Even various Department guidance documents provide that the SPLC (rather than the TCLP) should be used to determine if a material will leach metals into the ground water. See Respondents' Exhibits M, N, and O. Respondents' witness Foster collected three samples of HardieBoard deposited by Respondents at another site and submitted them to PPB Environmental Laboratories, Inc., in Gainesville, Florida, for a clinical analysis using the SPLC test. Those results, which have been accepted as being reliable,3 indicate that none of the leachate concentrations for arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver exceed (or even approach) the drinking water standards. Therefore, the material is virtually inert, and the groundwater quality will not be adversely impacted by use of this material as fill. The parties agree that the material is not a fire hazard. Prior to depositing the material, Mr. Stanton used a commercial waste reduction machine (a Smorcazy Bandit Beast 3680 Horizontal Trough Grinder) to grind or pulverize some of the material into fine particles. As noted earlier, a small amount of cellulose fibers are added to the product during the manufacturing process. The Department contends that after the grinding process occurs, these fibers will separate from the remaining fine particles and dissolve into the ground water. Because of this separation, the Department asserts that the material does not retain its physical or chemical structure after being deposited onto the property. Although cellulose fibers are added to the product during its preparation to strengthen the material (and have been added by cement manufacturers since the 1920s), they are distributed throughout the matrix in the material. This means that the fibers become "part and parcel of the mixture" and will not deteriorate, fall out, or leach out of the material even after routine grinding processes, such as that done by Respondents. As such, the cellulose is not biodegradable, and there is no concern that the cellulose will dissolve into the groundwater. Indeed, HardiePipe, which is used in the construction of culverts, storm sewers, and drainage pipes and has essentially the same constituents as HardieBoard, was approved by the Florida Department of Transportation in 2001 for use on State road and bridge projects. Therefore, it is found that the fill material will retain its physical and chemical structure after being deposited onto the ground. Expert testimony by Dr. McClellan established that the material meets the general definition of concrete, and because it is uncontaminated, it should properly be classified as uncontaminated concrete. As such, the material is clean debris and is not subject to the Department's solid waste management permitting requirements. Finally, the Department points out that the compressive strength (measured in pounds per square inch (PSI)) is much greater for concrete used in driveways than for HardiBoard (2500 PSI versus 20 to 30 PSI), and therefore Hardiboard is not a true concrete product. While the PSI values are indeed substantially different, the load bearing ratio or compressive strength of the material does not determine whether a material falls within the generic category of concrete. Water Issues As noted above, if a material is classified as clean debris, it may be deposited into an area prone to flooding or in a natural or artificial body of water, including groundwater (subject, of course, to other unrelated requirements or safeguards). There is no evidence that the filling occurred in a "natural or artificial water body," or directly into the groundwater. In addition, the evidence demonstrates that in October 2001, the ground next to the filled area had small pockets of standing water measuring no more than a few inches deep. However, when the inspection was made, and the photographs taken, Polk County was experiencing rather heavy rainfall, presumably due to the El Nino phenomenon. Whether these conditions (pockets of standing water) exist on the property only during the rainy season is not of record. Further, prior to the filling, Mr. Stanton contacted both the Southwest Florida Water Management District and the United States Geodetic Survey and he asserted, without contradiction, that neither agency indicated that his property was prone to flooding. In any event, even assuming that the area is subject to "frequent and periodic flooding," the permit requirements or other necessary safeguards, if any, associated with filling clean debris in such an area are not the subject of this proceeding. Investigative Costs A Department representative spent 66 hours investigating this matter for the Department. At a then-hourly rate of $18.54, this totals $1,223.64 in investigative costs. The reasonableness of this amount was not disputed by Respondents.
The Issue Whether the costs incurred by the Department of Environmental Protection, Bureau of Emergency Response (Department) in connection with its response to Incident Number 97-02-0234 may be recovered from Petitioner pursuant to Chapters 376 and 403, Florida Statutes.
Findings Of Fact The Department is a state regulatory agency charged with the responsibility of administering and enforcing the provisions of Chapters 376 and 403, Florida Statutes. Orchard View Development, Limited (Orchard View) is an Ontario, Canada corporation. Its president is William T. Lamsom. Orchard View is now, and has been since approximately two to six months prior to the incident which is the subject of this proceeding, the owner of a triangular, three-quarter acre parcel of undeveloped land (Orchard View's Parcel or the Parcel) located on the fringe of a Boca Raton, Florida residential neighborhood. There are children in the neighborhood who pass by the Parcel on their way to and from school. City streets border Orchard View's Parcel on all sides. Across one of these streets is a creek. Orchard View owns an additional 78 acres of undeveloped land (Orchard View's Acreage or the Acreage) to the north of its Parcel. Only a street separates the Acreage from the Parcel. Orchard View first acquired the Acreage in approximately 1975 and sold it about 14 or 15 years later. During this 14 or 15-year period, the Acreage was used by others, without Orchard View's approval or authorization, as a dumping ground. Numerous items, including boats, automobiles, tires, baby carriages, mattresses and landscaping material, were left abandoned on the property. Steps taken by Orchard View (which was well aware of the problem) to deter such dumping, including posting "no trespassing" signs on the property and erecting a 10-foot dirt barrier on one side of the property, were ineffective. Orchard View also complained to the police about the problem, but the making of these complaints did not result in an amelioration of the situation. Orchard View reacquired the Acreage at approximately the same time it acquired the Parcel. Since Orchard View's reacquisition of the Acreage, unauthorized persons have driven their all-terrain vehicles on the property without the approval or authorization of Orchard View, notwithstanding the "no trespassing" signs on the property. Although aware of the dumping problems in the area, Orchard View has not, at any time after its acquisition of the Parcel, posted "no trespassing" signs on the Parcel or erected a fence or other barrier around the Parcel, nor has it taken any other measure designed to discourage or prevent dumping on the Parcel. On June 9, 1997, at 11:10 a.m., the Department was notified by Lieutenant John Johnson of the Boca Raton Fire Department that four drums, which were labelled “poison and toxic,” had been discovered on the Parcel. The drums did not belong to Orchard View. They had been dumped on the Parcel by some person or persons not associated with Orchard View without Orchard View's knowledge, approval or authorization. Catherine Porthouse, an Environmental Specialist II with the Department, promptly responded to the scene (where she met Lieutenant Johnson) and served as the Department's on-scene coordinator. Because the drums were labelled “poison and toxic” and their contents were unknown, Lieutenant Johnson would not allow anyone, including Porthouse, to approach the drums without "Level B" protective clothing and equipment. Porthouse therefore initially viewed the drums from a distance using binoculars. She noted that three of the drums were leaking and that there was stained soil in the area of the drums. She also saw other solid waste materials nearby. Porthouse learned that Orchard View was the owner of the property on which the drums were located. At 12:49 p.m. on June 9, 1997, Porthouse telephoned Lamson and advised him that the drums were on the Parcel and that they needed to be removed by an "emergency response contractor." When informed about the presence of the drums on the Parcel, Lamson was not surprised. He realized (as he testified at hearing) that the area was "a good dumping ground." Lamson told Porthouse that he would ask his son, a general contractor who lived and worked near the Parcel, to remove the drums. Porthouse, however, explained to Lamson that the removal of the drums needed to be done by someone qualified, under state and federal law, to handle and transport hazardous substances. Lamson thereupon asked Porthouse to provide him with a list of "emergency response contractors" qualified to remove the drums. Porthouse gave Lamson her office and cellular phone numbers and asked him to call her back within no more than three hours to update her on his efforts to hire an "emergency response contractor" to remove the drums. Following Porthouse's telephone conversation with Lamson, the Department faxed to Lamson the list of qualified contractors Lamson had requested during the telephone conversation. After speaking with Porthouse, Lamson attempted to telephone his son. Lamson's son was not in, so Lamson left a message on his son's answering machine telling his son about his telephone conversation with Porthouse concerning the abandoned drums on the Parcel. In his message, Lamson asked that his son look into the matter. Neither Lamson, nor his son, made any arrangements for a qualified "emergency response contractor" to remove the drums from the Parcel; nor did either of them contact Porthouse and advise her that such arrangements had been made or would soon be made. Accordingly, at approximately 4:00 p.m. on June 9, 1997, after having waited over three hours for Lamson to provide her with such information, Porthouse hired Magnum Environmental Services (Magnum), a qualified "emergency response contractor" with whom the Department had a contract, to properly dispose of the four abandoned drums (and their contents), as well as the stained soil, on the Parcel. Magnum personnel (with "Level B" protective clothing and equipment) responded to the scene shortly thereafter. By approximately 6:30 or 7:00 p.m. that day (June 9, 1997), Magnum personnel had overpacked, removed from the Parcel and taken to an off-site hazardous waste storage facility the four abandoned drums (and their contents), as well as a fifth drum which contained the stained soil from the site (which Magnum had excavated). Before it had overpacked the drums and removed them from the Parcel, Magnum had examined and sampled the contents of each drum. The samples that Magnum had collected from the drums were sent to the laboratory for analysis. The analysis revealed the following: drum number 11 contained oil, barium, lead and toluene and had a flashpoint of less than 100 degrees Fahrenheit; drum number 2 contained oil mixed with water, as well as barium, lead and chromium, and had of flashpoint of between 101 and 139 degrees Fahrenheit; drum number 3 contained oil mixed with water, as well as barium and lead, and had of flashpoint of between 101 and 139 degrees Fahrenheit; drum number 4 contained oil mixed with water, as well as barium, lead and chromium, and had of flashpoint of over 200 degrees Fahrenheit; drum number 5 contained the soil that had been contaminated by spillage from drum numbers 2, 3 and 4 and had of flashpoint of between 101 and 139 degrees Fahrenheit. Magnum properly disposed of the drums based upon the results of its analysis. The Department paid Magnum $6,135.00 from the Water Quality Assurance Trust Fund for the services Magnum performed. In requesting Magnum to perform these services and in paying Magnum $6,135.00 for having done so, the Department acted reasonably and prudently. The amount it paid Magnum was not excessive.2 The Department reasonably incurred other expenses (also paid from the Water Quality Assurance Trust Fund) totaling $390.13 in connection with its response to the report it had received concerning the abandonment of the four drums on the Parcel. The total amount the Department paid from the Water Quality Assurance Trust Fund to have these abandoned drums properly removed from the Parcel and disposed of was $6,525.13. The Department is requesting that Orchard View reimburse the Department for these costs.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered by the Department finding that it is entitled to recover from Orchard View, pursuant to Chapters 376 and 403, Florida Statutes, the $6,525.13 in costs it reasonably incurred in connection with its response to Incident Number 97-02-0234. DONE AND ENTERED this 15th day of June, 1998, in Tallahassee, Leon County, Florida. STUART M. LERNER Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 SUNCOM 278-9675 Fax Filing (850) 921-6847 Filed with the Clerk of the Division of Administrative Hearings this 15th day of June, 1998.
The Issue The issue is whether Respondent Department of Environmental Protection (DEP) may issue to Respondent Republic Services of Florida, L.P. (Republic), permits to construct and operate a Class III landfill, pursuant to Permit Numbers 266830-003-SC/01 and 266830-004-SO/01, as modified as set forth below.
Findings Of Fact Background On June 30, 2009, Republic filed with DEP an application for a permit to construct and operate a Class I landfill (Application). In response to DEP's request for additional information dated July 30, 2009 (RAI), Republic filed a response dated September 14, 2009 (RRAI), upon receipt of which, DEP deemed the Application to be complete. References to the Application typically include the Application, RRAI, and other materials, such as reports, plans, and drawings, that are part of the Application, as well as three subsequent modifications, which are detailed below. Republic revised several reports, plans, and drawings in the RRAI; references to these items, such as the Engineering Report and Operation Plan, are to the versions contained in the RRAI. On November 13, 2009, DEP filed its intent to issue construction permit #266830- 003-SC/01 (Construction Permit) and intent to issue operation permit #266830-004-SO/01 (Operation Permit; collectively, the Permit). Republic Services, Inc. and its affiliates constitute the second largest waste-management operator group in the United States. Their market capitalization is just over $11 billion. The capitalization of the affiliate formed to operate the subject landfill is doubtlessly less than $11 billion, as the record does not suggest that any significant part of the overall capitalization of Republic Services, Inc., and its affiliates would be at risk in the operation of the proposed landfill. Republic presently owns and operates a Class III landfill in the City of Bartow, Polk County, known as the Cedar Trail Landfill. The oldest part of this landfill is an unlined Class III landfill of 52.5 acres in the center of the property owned by Republic. Immediately west of this unlined landfill is a 30.7-acre lined Class III landfill, which comprises cells 1-4. The Cedar Trail Landfill is located at 2500 West State Road 60, about three miles west northwest of the intersection of State Road 60 and State Road 98, which marks the center of Bartow. The landfill is immediately west of E.F. Griffin Road. Petitioners Frost live on E.F. Griffin Road, about one mile north of the Cedar Trail Landfill. Petitioner Highland Lakes Estates Homeowner's Association serves a residential subdivision known as Highland Lakes Estates. Highland Lakes Estates occupies a notch at the southeast corner of Republic's property. Aerial photographs reveal the changing land use of the land on which Cedar Trail Landfill is situated. Fifty years ago, the land was vacant with indications of agricultural uses. At the site of the proposed landfill were mostly citrus groves on the west side and some rangeland or vacant land on the east side. Ten years later, a large area immediately northeast of the subject land reveals the effects of strip mining for phosphate. Three years later, in 1971, the mined area had greatly expanded to encompass all or nearly all of the subject site and much of the surrounding area, including the western half of what would become Highland Lakes Estates. By 1980, the pits had been refilled and active mining had ceased, and the streets had been constructed for what is now known as Highland Lakes Estates. By 1993, about three dozen homes had been built in this residential, large-lot subdivision. 9. The Cedar Trail Landfill was constructed in the early 1990s as an unlined construction and demolition debris landfill. Now designated an approved landfill for Class III waste, this facility accepts such waste as is defined by Florida Administrative Code Rule 62-701.200(14) (2010), which includes construction and demolition debris, yard trash, processed tires, asbestos, carpet, paper, glass, furniture (but not white goods), plastic, and other materials not expected to produce leachate that presents a risk to the public health or environment. A zoning/land use map reveals that the land for which the proposed landfill is proposed is designated "sewage/borrow pits/spray fields." Highland Lakes Estates occupies land that is designated single-family residential with a density of one dwelling unit on up to 2.49 acres. The Cedar Trail Landfill has been the subject of three recent environmental resource permits (ERPs). Appendix R to the Application is an individual ERP issued in April 2009, and Appendix R to the RRAI is a conceptual ERP issued in March 2005. The April 2009 ERP mentions that the entire stormwater project was conceptually approved by an ERP issued on September 10, 2008, but this ERP is not part of the record. In any event, these ERPs approve the construction of a comprehensive stormwater or surface water management system for the entire Republic property. In particular, the April 2009 ERP permits the construction of a borrow pit at the southeast corner of the Republic property and a modification of the perimeter ditch/wet retention system. The April 2009 ERP states that the permitted stormwater management system will provide total onsite retention for runoff from the 100-year, 24-hour storm. The April 2009 ERP requires 2.8 acres of compensation for 2.8 acres of encroachment in the 100-year floodplain. Specific Condition 14 prohibits excavation of the borrow pits to a clay confining layer or limestone bedrock layer. Specific Condition 20 prohibits the mixing of leachate with stormwater and provides that, if leachate enters stormwater, the stormwater becomes leachate. Presumably reflecting this permitting activity, Application Drawing 4, as revised in the RRAI, is the site plan, including the unlined Class III landfill, the four-cell lined Class III landfill immediately to the west of the unlined landfill, and the eight cells proposed to accept Class I waste. These eight cells are immediately south of the four cells of the lined Class III landfill. The two northernmost of these eight cells abut, on their east boundary, the unlined Class III landfill. The remaining six cells abut, on their east boundary, an 800-foot wide borrow pit, which lies between these cells and Highland Lakes Estates. Immediately north of Highland Lake Estates is a second borrow pit, and west of this borrow pit is the unlined Class III landfill. The other major feature on the site plan is a third borrow pit running, from west to east, along the north border of the lined Class III cells, the unlined Class III landfill, and the second borrow pit. Bearing no signs of ambitious reclamation activity, the backfilled mining cuts host large water storage areas and, as described in the application for the March 2005 ERP, wetlands of "very poor quality." The backfilled soils are best described as complex surficial soils, consisting mostly of fine sands with varying amounts of organics, silts, and clays. Geotechnical investigations of the Cedar Trail Landfill suggest that mining depths, although variable, probably averaged 40 feet. Petitioners and Intervenor are substantially affected by the Permit and the construction and operation of the proposed landfill, which will stand nearly 200 feet above grade and will be the focus of substantial activity six days per week during its years of operation. Like Petitioners, Intervenor owns land in the immediate vicinity of the Cedar Trail Landfill, which is in the jurisdiction of Intervenor, and Intervenor's various municipal operations are much affected by whether the proposed Class I landfill is permitted. Among other things, Intervenor has agreed to accept untreated leachate from the proposed landfill. Petitioners Frost built their home in 1980 or 1981. During the hours of operation of the existing landfill, Petitioners Frost constantly hear the beeping noise of heavy- duty equipment, presumably a safety device when the equipment is moved. Over a dozen lots in Highland Lakes Estates abut the property line of the Cedar Trail Landfill, and the closest residence is about 1000 feet from the nearest proposed Class I cell. At present, the existing landfill subjects the Highland Lakes Estates to constant noise during operating hours and a coating of dust inside their homes. Several residents of Highland Lakes Estates testified. Hard-working people, some of whom are now retired, these residents decided to purchase homes in Highland Lakes Estates because it was a sunny, healthy place to live. Over time, most of these residents, by varying degrees, have come to accept the fact of the Class III operations at Cedar Trail Landfill, but they object to the substantial intensification of land use that will result from a regional Class I landfill. One resident testified that she finds in her pool dirt that has escaped from the existing landfill, and she has become concerned about her grandchildren coming over to swim. Another resident testified that he only began closing his windows five or six years ago when the noise levels at the existing landfill increased; he eventually had to install a window air- conditioner. The same resident testified that the green herons and snowy egrets that he used to see around his house have not returned for five years, and his wife, who has health problems, including respiratory distress, would suffer from the expanded landfill operations. Application, RRAI, and Permit, Including Modifications The Permit incorporates the Application, including the RRAI, Engineering Report, Operation Plan, and drawings. Thus, all of the documents are part of the Permit. In the Application, Republic proposes to convert cells 5-8, which are not yet constructed, from a Class III to a Class I landfill and add four new cells adjacent to the unused cells. The unfilled portion of Cells 1-4 would continue to receive only Class III waste. Pursuant to Florida Administrative Code Rule 62-701.200(13) (2010), Class I waste is all solid waste, other than hazardous waste, that is not otherwise prohibited by rule. The Application states that the proposed landfill will serve communities within 100 miles. The service area of this regional landfill will thus extend in central Florida from Marion to Osceola counties, along the Gulf Coast from Pasco to Lee counties, and along the Atlantic Coast from Volusia to Martin counties. As stated in the Application, this service area is populated by 9.7 million persons, who would daily account for 3000 tons of waste at the Cedar Trail Landfill. Initially, according to the Engineering Report, the proposed landfill will receive 1600 tons per day of Class I waste, but, once the existing Class III cells are filled, the proposed landfill will receive 1600 tons per day of Class I waste plus the 1400 tons per day of the Class III waste that is currently going into the existing landfill. As revised by the RRAI, the life expectancy of the proposed landfill is seven years. The Application states that Republic will employ an attendant, a trained operator, and 3-5 spotters at the landfill. The Application reports that the landfill would operate Monday through Saturday from 7:00 a.m. to 6:00 p.m. and that the working face would be covered daily. The Application reports that Republic would install seven new detection wells and use 17 existing wells for monitoring groundwater and would use two existing staff gauges for monitoring surface water, evidently at a single location, as discussed in the next paragraph. 23. Application Appendix V is the Water Monitoring Plan. Appendix V states that surface water will be monitored every time that the stormwater pond for the leachate storage area discharges offsite, but not more frequently than weekly. Application Drawing 4, as revised in the RRAI, shows that the sole surface water monitoring location is close to the leachate storage tanks, which are described below. 23. Appendix V also requires leachate monitoring, "at least annually," for five field parameters--specific conductivity, pH, dissolved oxygen, colors, and sheens; eight laboratory parameters--including chloride, mercury, and total dissolved solids; and the parameters listed in 40 CFS Part 258, Appendix II, which includes a comprehensive list of volatile organic compounds; persistent organic pollutants, including 2,3,7,8-TCDD (a major dioxin) and Dibenzofuran; and metals, including lead and chromium. Fourteen days prior to all sampling events, Republic is required to notify DEP, so that it may obtain split samples for its own analysis. Republic is required to report the results of the groundwater monitoring quarterly and to analyze the groundwater data in a technical report filed with DEP every two years. Appendix V also requires monitoring for odors and combustible gases, mostly methane. Republic will monitor combustible gas quarterly at various ambient locations, such as the office buildings and to monitor combustible gas quarterly in the soil down to the seasonal high water table. The purpose of this monitoring is to determine combustible gas concentrations and, if they exceed 25%, take "all necessary steps to ensure protection of human health." Some confusion in the Application arises as to the issue of whether the Cedar Trails Landfill will be subject to, or voluntarily implement, the more elaborate provisions applicable to a landfill covered under Title V of the federal Clean Air Act, as amended in 1990. Regulated emissions for a new source might include particulate matter, sulphur dioxide, nitrogen oxides, volatile organic compounds (VOCs), and specified hazardous air pollutants. Appendix V states that the landfill will become a Title V landfill once permitted to receive Class I waste, and, at that time, it will be subject to a "more comprehensive system of landfill gas collection and monitoring." Appendix V assures that these items "will be addressed in separate documentation from this monitoring plan"--and, apparently, separate from the present record. By contrast, the Operation Plan concedes only that, based on the nature of Class I waste and the design capacity of the proposed landfill, Cedar Trail Landfill "may" become a Title V facility. The Operation Plan states: "If the regulatory thresholds at [Cedar Trail Landfill] are met [under Title V] requiring an active gas collection and control system (GCCS), [Cedar Trail Landfill] will submit as required the GCCS design plans for approval and install an active gas extraction system within the regulatory timeframes specified by Title 40, Code of Federal Regulations, Part 60, Subpart WWW." More specific provisions in the Operation Plan identify best management practices to prevent objectionable odors. Four practices are identified, including an "active gas collection and extraction system." On the DEP form application, which is a cover sheet to the more elaborate application materials, Republic checked boxes indicating that the landfill would use active gas controls with gas flaring and gas recovery, which is probably what is meant by an "active gas collection and extraction system." The Application provides that the landfill liner would be double composite; the leachate collections system would consist of collection pipes, geonets, and a sand layer; the leachate would be stored in tanks; some of the leachate would be recirculated as spray on the working face; and the remainder of the leachate would be stored onsite and periodically transferred to a wastewater treatment center for treatment. The Engineering Report states that the waste disposal footprint will not be located where geological formations or other subsurface features will not provide support for the waste. The Engineering Report identifies appendices addressing the slope-stability analysis and foundation analysis and relies on a March 12, 1997, report by Ardaman & Associates, Inc. (Ardaman Report), January 23, 2004, report by Golder Associates, Inc. (Golder Report), and June 26, 2009, report by Hanecki Consulting Engineers, Inc. (Hanecki Report). These items are discussed in greater detail below in connection with the sinkhole issue. The Engineering Report assures that the waste disposal footprint will not be within 500 feet of an existing or approved potable water well, nor will it be within 1000 feet of an existing or approved potable water well serving a community water supply. The Engineering Report adds that the minimum horizontal distance between waste deposits and the property line is 100 feet. The Engineering Report assures that the landfill footprint will not be in a dewatered pit, as the installation elevations are at least 2-3 feet higher than the seasonal high water table. The Engineering Report acknowledges that a small part of the eastern end of the four southernmost cells lies within the 100-year floodplain, as depicted by the Flood Insurance Rate Map effective December 29, 2000, and as shown in Application Appendix A, Drawing 1. Claiming that the relevant map was not revised in 2000, the Engineering Report asserts that the last update to the FIRM map was in 1975, and the depicted floodplain was filled during the mine reclamation process. The Engineering Report notes that the floodplain concerns were addressed in the April 2009 ERP. 34. The Engineering Report discloses two enforcement actions against Republic at the Cedar Trail Landfill. In a letter dated October 19, 2001, DEP warned Republic about noncompliant items at the site, and, in a notice of noncompliance dated January 30, 2006, DEP warned Republic not to use a new cell prior to construction certification of the cell's stormwater system. Both matters were reportedly resolved, and Republic has not been the subject of other enforcement actions for the Cedar Trails Landfill. At DEP's urging, the RRAI elaborates on enforcement actions against Republic or, evidently, Republic affiliates at a variety of Florida facilities, not just landfills. The additional information reveals that DEP imposed a fine of $61,300 for the October 2001 violations, which included disposing of unacceptable waste, storing an excessive number of tires and exceeding groundwater standards without notifying DEP, and a fine of $1000 for the January 2006 notice of noncompliance. The other enforcement actions against Republic or affiliates concerning landfills involved consent orders about the Nine Mile Road Landfill (Seaboard Waste): in February 2003, DEP imposed a fine of $13,000 in settlement of charges that employees were not removing all unacceptable waste from the site and, in November 2005, DEP imposed a $285 fine for a failure to submit required stormwater monitoring reports. There were many other enforcement actions, generally resulting in modest fines, but they involved hauling facilities, transfer stations, and materials recovery facilities, not landfills. The Engineering Report states that the proposed landfill is within six miles of, but greater than 10,000 feet from, the Bartow Municipal Airport. Airport safety is addressed in more detail below. The Engineering Report describes in detail the double composite liner system, which uses materials whose physical, chemical, and mechanical properties prevent failure due to contact with Class I waste and leachate, climactic conditions, installation stress, and other applied stresses and hydraulic pressures. The Engineering Report performs no contingency sinkhole analysis. The report does not suggest that the liner system could withstand the stresses and pressures resulting from any size sinkhole, so the necessary inference is that the liner will fail if any sinkhole forms directly beneath it. The Engineering Report states that waste placement will remain within the lined containment berm. The Engineering Report describes in detail the double composite liner system for use at the proposed landfill. The primary liner system and secondary liner system each comprises three layers with the top layer consisting of a composite drainage net, the middle layer consisting of a high-density polyethylene geomembrane with a minimum average thickness of 60 ml, and the bottom layer consisting of a geosynthetic clay liner with a maximum hydraulic conductivity of 5 x 10-9 cm/second. The Engineering Report describes in detail the leachate collection and removal system, which, sitting atop the primary liner, includes a 24-inch thick sand drainage layer with a minimum hydraulic conductivity of 1 x 10-3 cm/second, a composite drainage net, and a single perforated 8-inch diameter lateral pipe in each cell. The collection lateral pipes will gravity drain to the east to a header pipe that gravity drains to the primary leachate collection pump stations--one station for the four converted cells and one station for the four new cells. A smaller leachate collection and removal system will handle the leachate that penetrates to the leak detection layer by routing it to a secondary leachate collection pump station. Based on calculations derived from the HELP groundwater model, the leachate collection and removal system is designed to prevent leachate head from exceeding the thickness of the composite drainage net (about 1 cm) over the secondary geomembrane and from exceeding one foot over the primary geomembrane. According to the Engineering Report, flow meters will be installed at each of the pump stations to allow daily readings of the amount of leachate being pumped. At one foot of head over the primary liner, the Engineering Report expects just over three gallons per day collected at each secondary leachate collection pump station--significantly less than the leakage rate typical of a double liner system without a geosynthetic clay liner beneath the primary liner. However, the Engineering Report provides a standard action leakage rate of 100 gallons/acre/day, meaning that Republic is required to report to DEP liner leakage only when this leakage rate is attained. The pump stations will transmit the leachate to one of two above-ground, 150,000-gallon storage tanks. From these tanks, most of the leachate will be transported to an offsite location for treatment. However, up to 12,000 gallons per day of the untreated leachate will be recirculated to be sprayed on the working faces of the landfill. This is to control dust and possibly to assist with the degradation of the waste. The Engineering Report states that the Cedar Trail Landfill implements a facility-wide water quality monitoring plan. Upon completion of the pump stations for the eight cells that are the subject of the Application, Republic will expand its leachate sampling program to include annual sampling of the leachate collected in the primary and secondary leachate collection pump stations. The groundwater monitoring wells would be installed as closely as possible to the outer edge of the roadway that, with a stormwater ditch, will run the perimeter of the proposed Class I landfill. In the revised Engineering Report contained in the RRAI, Republic proposes a surface water discharge point in the stormwater pond located near the leachate storage tanks. The Engineering Report adds that Republic will continue to comply with the following prohibitions: No waste will be knowingly burned on site; Hazardous waste will not knowingly be accepted; PCB contaminated waste will not knowingly be accepted; Untreated biomedical waste will not knowingly be accepted. Please note that treated biomedical waste may be accepted at [Cedar Trail Landfill]'s Class I Landfill provided that the waste containers are marked "Treated Biomedical Waste.;" No waste disposal at the proposed Class I Landfill will occur within 3,000 feet of a Class I surface water body; [Cedar Trails Landfill] will not knowingly accept liquid waste within containers, excluding leachate and gas condensate derived from solid waste disposal operations. [Cedar Trails Landfill] will comply with the requirements of Rule 62- 701.300(10), FAC regarding the handling of liquid wastes; Neither oily waste nor commingled oily waste will knowingly be accepted; and Lead-acid batteries, used oil, white goods, and whole-waste tires will not knowingly be disposed of in the Class I waste disposal system. The Joint Stipulation to Permit Modification, identified above, adds four items to this list of operational prohibitions: i. Garbage will not be knowingly accepted; Household Waste, except waste from residential sources generated as Class III waste, will not be knowingly accepted; Animal carcasses will not be knowingly accepted; and Aluminum dross will not be knowingly accepted. Capitalized terms are generally defined in the Florida Administrative Code. Florida Administrative Code Rule 62-701.200(39) defines "Garbage" as " all kitchen and table food waste, and animal or vegetative waste that is attendant with or results from the storage, preparation, cooking, or handling of food materials." Application Appendix H is the Operation Plan, which also identifies the types of wastes to be permitted at the proposed landfill. Section 3(b) of the Operation Plan authorizes the proposed landfill to accept: Commercial waste Ash residue Incinerator by-pass waste Construction and demolition debris, including from a residence Treated biomedical waste Agricultural waste Industrial waste Yard trash, including from a residence Sewage sludge Industrial sludge Water/air treatment sludges Waste tires De minimis amounts of non-hazardous waste from incidental residential sources Section 5 of the Operation Plan provides, in relevant part: [Cedar Trail Landfill] will accept waste included in any of the waste categories identified under Section 3(b) of this Operation Plan[, but] will . . . NOT knowingly accept any hazardous waste, untreated biomedical waste, liquid waste (including paint), explosive waste, toxic waste, or radioactive waste for disposal at the [Cedar Trail Landfill.] Unacceptable types of refuse are listed below and will not be knowingly accepted for disposal. --Hazardous waste --Explosive waste --Radioactive waste --Drums that have not been opened and Emptied --Refrigerators, freezers, air Conditioners (white goods) --Any toxic or hazardous materials, i.e. batteries, solvents, oil, etc. --Automobiles or parts that contain fuel, lubricants, or coolants --Untreated Biomedical waste The original Application prohibited the acceptance of septic tank pumpage, but the application form accompanying the original Application indicated that the proposed landfill would accept industrial sludge and domestic sludge. After modification by the RRAI, the prohibition against accepting septic tank pumpage was deleted, and the Operating Plan added, among acceptable wastes, sewage sludge, industrial sludge, and water- and air-treatment sludge. Florida Administrative Code Rule 62-701.200(101) (2001) defines "sludge" to include solid waste pollution control residual from an industrial or domestic wastewater treatment plant, water supply treatment plant, air pollution control facility, septic tank, grease trap, portable toilet, or other source generating a waste with similar characteristics. Florida Administrative Code 62-701.200(64) (2001) defines "liquid waste" as any waste with free liquids, according to the "Paint Filler Liquids Test." As modified by the Joint Stipulation to Permit Modification, Section 5 of the Operation Plan was amended to add the following items to unacceptable types of refuse that will not be knowingly accepted for disposal: --Garbage --Household Waste, except waste from residential sources generated as Class III waste --Animal carcasses --Aluminum dross At the hearing, Republic and DEP agreed to an additional condition to the Operation Plan that unacceptable waste would include Garbage contained in commercial, industrial or agricultural waste. According to the Operation Plan, the initial waste screening occurs at the gate house where the attendant interviews the driver and inspects the incoming waste load. If the attendant sees more than a negligible amount of unauthorized wastes, he will reject the load and will contact the hauler to identify the source of the waste. Additionally, Republic will notify DEP if anyone tries to dispose of hazardous waste at the proposed landfill. As modified by the Joint Stipulation to Permit Modification, the Operation Plan was amended to provide a new paragraph between the paragraph addressing the initial waste screening at the gate house and, as discussed below, the second screening at the working face. The new paragraph provides: Any malodorous waste will be covered with mulch and/or additional soil or other approved cover materials to control odors promptly, within one (1) hour from the time of unloading, except in the event of exigent circumstances, such as extreme weather. Cedar Trail Landfill will promptly cover any sludge deposited on the landfill working face within one (1) hour from the time of the unloading, except in the event of exigent circumstances, such as extreme weather. At the hearing, Republic and DEP agreed to an additional condition to the Operation Plan, which would prohibit Republic from accepting malodorous waste or sludge that, due to exigent circumstances, it would not be able to cover within one hour from the time of unloading. If the load passes the initial waste screening, it will proceed to the working face of the landfill, according to the Operation Plan. At least one spotter will be stationed at the working face at all times that the landfill receives waste. Her job will be to detect unauthorized wastes. Republic is to assure that it has a sufficient number of spotters to find and remove unauthorized waste prior to compaction. The Operation Plan allows the spotter to work from ground level or the cab of a compactor. If the operator of a piece of heavy equipment is trained as a spotter, she may also serve as a spotter. During periods of higher waste traffic, the equipment operator will, according to the Operation Plan, "likely" need the assistance of another operator or spotter to screen the higher waste volumes. When finding unauthorized wastes in manageable volumes, the spotter or operator will remove these wastes by hand and place them into nearby containers for removal to an appropriate facility. The third waste screen occurs as the equipment operator spreads the waste, pursuant to the Operation Plan. The equipment operator is required to place any unacceptable observed wastes into containers, which will be located "within the lined area." These wastes will also be removed to an appropriate facility. In the RAI, DEP questioned the proximity of the containers to the working face, as the lined area consists of 72 acres, but, in the RRAI, Republic ignored the comment, restating only that the containers would not be located outside the lined area. The Operation Plan specifies a filling sequence. Republic will assure that the first layer of waste placed above the liner in each cell will be a minimum of four feet in compacted thickness and will be free of rigid objects that could damage the liner or leachate collection and removal system. Republic will maintain the working face to minimize the amount of exposed waste and initial cover necessary at the end of each day. The filling sequence will proceed until the permitted final grade elevations have been reached, less three feet for the final cover. The Operation Plan states that the initial cover at the Class I landfill will consist of a six-inch layer of soil that is transferred from onsite borrow pits or offsite sources. This soil will be compacted and placed on top of the waste by the end of each work day. At Republic's option, subject to DEP's approval, it may use a spray-on or tarpaulin cover, instead of a soil cover. The Operation Plan requires Republic to apply at least one foot of intermediate cover within seven days of cell completion, if additional waste will not be deposited within 180 days of cell completion. Republic may remove all or part of this intermediate cover before placing additional waste or the final cover. Through the placement of initial, daily, and intermediate cover, Republic will minimize the occurrence of moisture infiltration, fires, odors, blowing litter, and animals and other disease vectors. 59. The Operation Plan requires Republic to control litter primarily by daily waste compaction and cover. However, at least daily, if needed, employees will collect litter along the entrance and access roads and around the working face. Complaints about litter must be logged. In addition to the inspections detailed above, the Operation Plan establishes a random load-checking program to detect unauthorized wastes. Each week, Republic employees will examine at least three random loads of solid waste by requiring drivers to discharge their loads at a designated location within the landfill where the employees may undertake a detailed inspection. All random inspections will be logged. Notwithstanding the daily limit of 12,000 gallons per day, the Operation Plan prohibits Republic from spraying leachate during rain events. To apply the recirculated leachate, the lead operator will drive the leachate tanker truck on the working face, so that it can spray leachate over waste as it is being compacted, but after it has been screened by spotters. The spraying will be done to avoid causing leachate to pond atop the waste and will not be done within 50 feet of an outside slope. No restrictions apply to wind conditions. The Operation Plan states that, if the annual sampling of leachate water quality at the two pump stations reveals a contaminant in excess of the permissible limits listed in 40 CFR Part 261.24, Republic will start monthly sampling and notify DEP in writing. Also, the Cedar Trail Landfill will maintain a recording rain gauge. The Operation Plan requires Republic employees to conduct daily surveys for objectionable odors and take immediate corrective action, if odors are found at the property line. As modified by the Joint Stipulation to Permit Modification, this portion of the Operation Plan was amended to add two odor- remediation actions and another form of odor inspection. The two additional actions to prevent odors are to 1) provide additional cover using mulch, additional soil, or other approved cover material and 2) use odor masking or neutralizing agents. The new inspection provision states: Internal inspection will be performed on a weekly basis by a properly trained odor ranger or equivalently trained person. Such individual will tour the facility, property boundary, and the subdivision of Highland Lakes Estates . . . to identify any odors leaving the Landfill's property boundaries. The results of each weekly inspection will be document, and any odors identified will be mitigated. Another new provision from the Joint Stipulation for Permit Modification applies to the handling of sludge. As amended, the Operation Plan states: When accepting sludge from a new source or distributor, [Republic] will obtain information regarding the characteristics and constituents of the sludge, including a description of the industrial process or circumstances that resulted in the generation of the sludge. Upon delivery of the sludge, [Republic] will mix lime, sodium hydroxide, or any other suitable agents to eliminate objectionable odors as required during disposal of the sludge before the material is covered. Furthermore, [Republic] will obtain advance notice from contributors prior to delivery of any sludge and shall promptly cover any sludge unloaded on the landfill working face within one (1) hour from the time of unloading, except in the event of exigent circumstances, such as severe weather. [Republic] shall use its best efforts to avoid accepting or disposing of sludge on Saturdays, Sundays, or public holidays. Additionally, with respect to sludge received from wastewater treatment facilities only, such sludge shall not exceed the lesser of (1) twenty percent (20%) of the total volume of waste disposed in the landfill on an average monthly basis, determined annually on the prior calendar year, or (2) two-hundred (200) tons per day, averaged over the prior 12-month calendar year. Republic is required to monitor combustible gases quarterly and transmit the results to DEP, according to the Operation Plan. If Republic detects methane above the limits specified in Florida Administrative Code Rule 62-701.530 (2010), Republic must submit a gas remediation plan to DEP within seven days. The Operating Plan indicates that the separation of the waste from the groundwater prevents the saturation of the waste and, thus, the generation of odor. Sloping and compacting will promote stormwater runoff, again to discourage the generation of odor. The Construction Permit authorizes construction of the proposed landfill in accordance with the "rules[,] . . . reports, plans and other information" submitted by Republic "(unless otherwise specified)." This parenthetical reference provides that the provisions of the Construction Permit control over any contrary provisions in the other documents that are part of the Permit due to incorporation by reference. In addition to the original Application, RRAI, and drawings, the Construction Permit also incorporates Florida Administrative Code Chapter 62-701 (2001). The Construction Permit states that Republic may not violate the prohibitions set forth in Florida Administrative Code Rule 62-701.300, which is discussed in the Conclusions of Law. Construction Permit Specific Condition A.9.a requires notification to DEP of the discovery of limestone during excavation or discovery. Specific Condition A.9.b requires notification to DEP of any surface depressions or other indications of sinkhole activity onsite or within 500 feet of the site. Specific Condition A.9.c prohibits open burning. Construction Permit Specific Condition C.1.b prohibits the discharge of leachate, during construction or operation, to soils, surface water, or groundwater outside the liner and leachate management system. Specific Condition C.4 prohibits the acceptance of hazardous waste and does not condition this prohibition on Republic's knowledge that the waste is a hazardous waste. Specific Condition C.5 requires Republic to "control . . . odors and fugitive particulates (dust)" and "minimize the creation of nuisance conditions on adjoining property." "Nuisance conditions" include "complaints confirmed by [DEP] personnel upon site inspection." Specific Condition C.5 orders Republic to "take immediate corrective action to abate the nuisance" and to "control disease vectors so as to protect the public health and welfare." Construction Permit Specific Condition C.6.b requires immediate notice to DEP of any sinkholes or other subsurface instability. Specific Condition C.8 requires Republic to manage leachate in accordance with the Operating Permit and Florida Administrative Code Rule 62-700.500(8). The Operating Permit incorporates the same materials that are incorporated into the Construction Permit, again "(unless otherwise specified)." Like the Construction Permit, the Operating Permit incorporates Florida Administrative Code Chapter 62-701 (2001) and requires immediate notice to DEP in the event of a sinkhole or subsurface instability. The Operating Permit specifies that the action leakage rate is 100 gallons per acre per day and the leachate recirculation rate is 12,000 gallons per day. As modified by the Joint Stipulation to Permit Modification, Operating Permit Specific Condition A.1.b states: This Facility is not authorized to accept Garbage; untreated Biomedical Waste; animal carcasses; liquids and non-liquid PCB containing materials or wastes with a PCB concentration greater than or equal to 50 parts per million; Liquid Waste; and aluminum dross. Additionally, this facility is not authorized to accept Household Waste, except waste from residential sources generated as Class III waste. Class III waste means yard trash, construction and demolition debris, processed tires, asbestos, carpet, cardboard, paper, glass, plastic, furniture other than appliances, or other materials approved by [DEP] that are not expected to produce leachate which are a threat to public health or the environment as defined in Rule 62-701.200(14), F.A.C. Based on this authorization to allow certain wastes as described above from residential sources, and since the landfill design, including liner and leachate collection systems, meets the requirements of Chapter 62-701, F.A.C., for Class I landfills, the facility will be entitled to [the] household hazardous waste exemption pursuant to 40 C.F.R. 261.4(b)(1). Specific Condition A.9.c prohibits open burning. Operating Permit Specific Condition C.1.b prohibits the discharge of leachate to soils, surface water, or groundwater outside the liner. Specific Condition C.1.c prohibits the discharge of "residual contaminants," such as gasoline, oil, paint, antifreeze, and polychlorinated biphenyls (PCBs), onto the ground or into surface water or groundwater. Operating Permit Specific Condition C.1.k(1) provides that authorized waste types are those listed in Section 3(b) of the Operations Plan, and unacceptable wastes shall be removed from the site as described in Sections 3(a) and 7. As modified by the Joint Stipulation to Permit Modification, Operating Permit Specific Condition C.1.k(1) provides: "Waste types authorized for management at this site are those listed in Section 3(b) of the Operations [sic] Plan. Unacceptable wastes are those listed in Section 5 [of the Operation Plan] " Operating Permit Specific Condition C.1.k(2) requires the use of a sufficient number of spotters to remove unacceptable wastes, but allows Republic to direct its equipment operators to serve as spotters from the equipment. This condition allows DEP to require that spotters work from the ground, if DEP determines that spotting from equipment is not effective. Specific Condition C.1.k(3) requires Republic to remove unacceptable wastes immediately and not to unload additional wastes in the immediate vicinity until placing unacceptable wastes in the designated waste containers" "near the working face" and within the lined landfill area. Operating Permit Specific Condition C.1.l(2) requires Republic to inspect on each operating day the property boundary for objectionable odors and, if any are detected, abate them in accordance with Specific Condition C.5. Specific Condition C.5.a requires Republic to control odors, disease vectors (insects and rodents), and fugitive particles (dust and smoke) to protect the public health and welfare. Control is defined as "minimiz[ing]" the creation of nuisance conditions on adjoining property. Odors confirmed by DEP personnel are a nuisance condition, and Republic must take immediate corrective action to "abate" the nuisance. Specific Condition C.5.b provides that, if odor control measures do not "sufficiently abate" objectionable odors within 30 days, Republic will submit an odor remediation plan to DEP for approval. Operating Permit Specific Condition C.8.e requires monthly reports to DEP of leachate quantities. Specific Condition C.8.h(1) prohibits recirculation of leachate at rates that result in seepage that may discharge outside the lined area. Leachate may not be sprayed when the application area is saturated or during a rainfall event. There is no prohibition against spraying during windy conditions. Operating Permit Specific Condition E details the extensive water quality monitoring requirements. However, Specific Condition E.9.b requires only annual testing of the five field parameters, eight laboratory parameters, and the comprehensive list of Appendix II parameters set forth in 40 CFR Part 258, all of which are identified below. Specific Condition E.9.c provides that, if a contaminant listed in 40 CFR 261.24 exceeds the level listed therein, Republic will notify DEP and take monthly leachate samples until no exceedances are detected for three consecutive months. Operating Permit Specific Condition F.1.a states: "This solid waste permit will meet the statutory requirement to obtain an air construction permit before . . . constructing a source of air pollution, except for those landfills that are subject to the prevention of significant deterioration (PSD) requirements of Chapter 62-212, F.A.C." Such facilities are required to obtain an air construction permit from the Bureau of Air Regulations prior to construction. Specific Condition F.1.b requires Republic to comply with Title V of 40 CFR 60, Subparts WWW and CC. This section notes that Title V permit applications must be submitted to the District Air Program Administrator or County Air Program Administrator responsible for the landfill. Aviation Safety Landfills attract birds in search of food. Flying birds may interfere with aviation safety. Thus, landfills are typically not located in close proximity to airfields to minimize the risk that flying birds will interfere with airborne aircraft approaching or departing from an airport. The nearest airport to the Cedar Trail Landfill is the Bartow Municipal Airport, which is operated by the Bartow Aviation Development Authority. This airport is over five miles from the footprint of the active landfill and 4.6 miles from the boundary of the proposed site. Republic provided notice of the Application to all airports within six miles of the proposed landfill, the Federal Aviation Administration, and the Florida Department of Transportation. None of these entities objected to the proposed landfill. When Republic gave the Bartow Aviation Development Authority notice of an earlier application, which sought a permit for a landfill that would accept garbage, the authority objected to the proposal due to concerns posed by birds to aviation safety. When asked about the Application, the authority's executive director testified that she still has concerns about the proposed landfill, but she did not specify the nature of her concerns or her analysis. As explained in the Conclusions of Law, these are the only facts required for a determination of whether Republic has provided reasonable assurance of aviation safety. The record provides no basis for finding that Republic has failed to provide reasonable assurance of aviation safety. Neither the FAA nor the Bartow Aviation Development Authority has objected to the proposed landfill. The executive director's unspecified concerns do not override the absence of a formal objection from these agencies. Petitioners assign too much weight to the earlier objection submitted by the authority. The composition of the authority may have changed or some authority members may have decided they were wrong in their earlier analysis. This earlier objection does not outweigh the absence of objection to the present proposal from any of the aviation agencies and the absence of any evidence of the expected nature or extent of bird usage of the proposed landfill and the extent to which these birds would interfere with existing and expected flight paths of aircraft using the Bartow Municipal Airport. Public Health Petitioners' expert witness on public-health issues, Dr. David Carpenter, is a medical doctor with a long, prestigious history of public service, including with the Department of Defense, the National Institutes of Mental Health, the United States Public Health Service, and the New York Department of Health, where he served as director from 1980-85. At that time, Dr. Carpenter started the School of Public Health at the University of Albany. Republic's expert witness on public-health issues, Dr. Christopher Teaf, is an expert in the evaluation of environmental contamination, waste management, and toxicology, but not a medical doctor. Dr. Teaf is a professor at Florida State University and owns a small consulting firm. The major part of Dr. Carpenter's career has been devoted to research. For the past ten years, he has focused more on human health, especially human disease from exposure to environmental contaminants. Dr. Carpenter has considerable experience with the adverse effects of landfills on human health, but his experience has been mostly with older landfills, where containment measures were few and offsite releases were many. Clearly, Dr. Carpenter's experience does not extend to the role of landfill design, construction, and operation in the transmission of human disease. Thus, Dr. Carpenter is qualified to opine on the effects of pollutants that may escape landfills, but not on the relationship of landfill design, construction, and operation on the probability that a landfill will transmit pollutants. For the most part, Dr. Carpenter did not attempt to address matters outside of his expertise. However, Dr. Carpenter testified that the risk of disease or injury increased in relationship to the proximity of the person to the landfill. This testimony can only be credited if one assumes that the landfills are identical in terms of design, construction, and operation and in terms of the environmental conditions of the landfill site. In other words, in real-world applications, it is impossible to credit this element of Dr. Carpenter's testimony, especially to the extent of his implicit suggestion that public health is unreasonably endangered by the construction of a landfill, in compliance with all rules, that satisfies all of the separation criteria and design criteria set forth in the rules, as discussed below. By contrast, Dr. Teaf focused on the details of the proposed landfill. Applying his knowledge of toxicology, Dr. Teaf determined that the proposed landfill adequately protects public health. In making this determination, Dr. Teaf analyzed the effects of various design and operational characteristics of the proposed landfill, including the double liner system, the leachate collection and management system, the selection of appropriate waste types, the procedures for the evaluation and covering of sludges, the prohibition against municipal garbage, the restrictions on household items, the monitoring of groundwater and surface water, the stormwater management system, and the plans to control dust and odors. Dr. Carpenter's testimony and the literature that he sponsored suggested important links between older landfills and a wide range of human disease. But the recurring problem with Dr. Carpenter's testimony and the research articles that he sponsored was the inability to link this information to the proposed landfill. All of the landfills studied in his research articles were older, and most of them appeared to have been designed, constructed, and operated under far more relaxed regulatory regimes than exist today. Nothing in Dr. Carpenter's testimony or sponsored literature attempted to delineate the design or operational characteristics of these landfills, such as whether they were double- or even single-lined, served by leachate circulation and recovery systems, limited as to materials that they could accept, or required to install stormwater management and water monitoring systems. 93. Analysis of the risk to public health posed by the proposed landfill requires consideration of the various means of transmission of the pollutants received by the landfill: water, land, and air. Of these, water requires little analysis, on this record. Even Dr. Carpenter conceded that the proposed landfill does not appear to pose a threat to groundwater. The double liner, leachate collection and recovery system, and groundwater monitoring plan support the finding that groundwater transmission of pollutants from the proposed landfill is unlikely. Transmission by surface water is also unlikely. Compared to groundwater monitoring, surface water monitoring is limited. For instance, there is only a single monitoring site. Also, as noted above, the stormwater pond for the leachate storage area is expected to discharge stormwater offsite during excessive storm events, at which time surface water samples will be taken. However, a comprehensive surface water management system is in place at the landfill and will prevent offsite discharges in all but a few excessive rain events. Transmission by land is also unlikely. The Application contains engineering analysis of the proposed stability of the side slopes and a determination that they will be stable. The discussion of sinkholes, below, does not affect this finding. Treating dust as transmission by air, the only other means by which pollutants may transmit by land is by animals, such as insects, rodents, and birds. An important factor limiting the activity of animals in spreading pollutants offsite is the fact that the proposed landfill will not receive garbage. Although putrescible waste may be received within other categories of waste, the prohibition against receiving garbage will greatly reduce the amount of potential food sources for animals and thus the utilization rate of the proposed landfill by these animals. A further reduction in animal utilization will be achieved through the daily and intermediate cover requirements. Thus, transmission of pollutants by animals is also unlikely. Transmission by air takes several forms. Pollutants may be transmitted as or on dust, with water in the form of aerosol, or as gas. In terms of how transmission by air is addressed by the Permit, this means of transmission potentially represents a greater threat than transmission by water or land for four reasons. First, the explicit focus of the Permit, as to gas, is to avoid explosive concentrations of methane and objectionable odors, but not the transmission of other pollutants by air. Second, the effect of the Permit is to prohibit the release of pollutants into the groundwater or offsite surface water and to prohibit the release of pollutant-bearing land offsite, but no such flat prohibition applies to the offsite release of pollutants by air. Third, the leachate recirculation system provides a good opportunity for the release of certain pollutants into the air by aerosol or evaporation, but similar releases to offsite land, surface water, or groundwater are prohibited. Fourth, scientific understanding of the effects of exposure, especially by inhalation, to pollutants, especially in the form of organic compounds, is continuing to develop: with the use of chemicals increasing three fold in the 50 years preceding 1995 and approximately 80,000 chemicals in use in 2002, only a few hundreds of these chemicals have been subjected to long- or short-term study, resulting in the discovery that about 10% of the chemicals in use in 2002 were carcinogens. Transmission by dust appears to be limited by the frequent covering and spraying of the working faces. Although nearby residents complain of dust in their homes, the practices of the less-regulated Class III landfill cannot be extrapolated to the proposed Class I landfill. Thus, the prospect of dust transmission of chemicals contained in the fill received by the proposed landfill appears also to be slight. The use of untreated leachate as the spray medium to control the dust itself raises two risks, however. First, spraying leachate will release chemicals in aerosol. The potential range of aerosol is great, especially as the landfill ascends toward its design height of 190 feet. However, the risk of transmission by aerosol is reduced to insubstantial levels by adding a Permit condition that prohibits spraying during windy conditions. Second, depositing leachate on the landfill face will release chemicals through evaporation. The point of spraying the landfill face is to control dust between the addition of the waste materials to the pile and the application of the cover. Between these two events, dry conditions will sometimes intervene and may cause the evaporation of certain, but not all, pollutants. The leachate acquires pollutants as it percolates down the waste column and into the leachate collection system. As Dr. Teaf noted, the leachate becomes more concentrated as it recirculates, but, otherwise, this record is largely silent as to the likely composition of the recirculated leachate. However, for landfills accepting sludge, higher levels of mercury may be present in the leachate. As reported by the Florida Center for Solid and Hazardous Waste Management at the University of Florida, in a report issued March 2007, and titled, "Design and Operational Issues Related to Co-Disposal of Sludges and Biosolids and Class I Landfills--Phase III," one study found that the concentration of mercury in the leachate of landfills that receive sludge is almost three times greater than the concentration of mercury in the leachate of landfills that do not accept sludge. The same study reported that total dissolved solids and chlorides were present at greater concentrations at the landfills that did not accept sludge and that other parameters--unidentified in the cited article--were not significantly different between the two types of landfills. Republic proposes to recirculate substantial volumes of leachate--sufficient, for instance, to raise the moisture content of the fill from 25 percent to 28.9 percent. The Permit allows the proposed landfill to operate six days per week, for a total of 312 days annually. The Operation Plan prohibits the application of leachate during rain, but the number of days annually during which rain extends for the entire day is few, probably no more than a dozen. These numbers suggest that Republic may apply as much as 3.6 million gallons annually of untreated leachate to the landfill face. The 12,000 gallon-per-day limit and restrictions on head in the leachate collection and removal system effectively limit the quantities of leachate that may be recirculated, but the sole provision addressing leachate water quality is the annual monitoring event described above. Given the time required to analyze the many parameters included in the EPA regulation, for most of the year between tests, Republic will be applying over three million gallons of leachate whose pollutant concentrations will be completely unknown. Some assurances emerge, though, when considering air transmission of pollutants by class. In general, on this record, as to transmission by gas, there appears to be an inverse relationship between a compound's volatility, which is a measure of its ability to enter the air, and a compound's persistence. VOCs are one of the most dangerous classes of pollutants to public health and include such carcinogens as benzene, tolulene, xylene and, the most dangerous of all VOCs, vinyl chloride, which is released upon the degradation of such common substances as plastics, carpets, and upholstery. Biogas, which is generated by the anerobic decomposition of organic compounds in a landfill, contains mostly methane and carbon dioxide, but also significant levels of VOCs. When inhaled, the primary results of exposure to VOC are respiratory irritation and allergenic effects. Volatility is measured by vapor pressure, which is a measure of a chemical's ability to get into the air. As their name suggests, VOCs enter the air easily. They are also capable of traveling great distances due to their light molecule. However, VOCs are easily destroyed by sunlight and diluted by wind. Other organic compounds common to landfills are only semi-VOCs, such as PCBs. Although less volatile, these chemicals, too, are hazardous to public health--in the case of PCBs, in any amount. Due to this fact and their persistence in the environment, the United States has prohibited the manufacture of PCBs for over 30 years. However, not only are PCBs considerably less likely to enter the air than VOCs, they also travel shorter distances than VOCs due to a heavier molecule. Dr. Carpenter opined that there is little evidence that PCBs are an issue in the proposed landfill. Another class of organic compound, 1000 times less volatile than even PCBs, is phthalates, which are used in the production of plastics. Phthalates pose significant threats to public health, especially reproductive health. However, the exceptionally low volatility of this compound renders transmission by evaporation highly unlikely. Much of the regulatory framework imposed on landfill design, construction, and operation arises out of concerns for the control of human pathogens, which are infection-causing organisms, such as bacteria, viruses, protozoa, and parasitic worms. One of the great advances in human longevity in the United States occurred in the early 1900s--not with the development of antibiotics or improved medical care--but with the implementation of basic sanitation control and the removal of pathogens from the drinking water. For the proposed landfill, sludge will be the primary source of pathogens. Sludge is nutrient-rich organic matter, which will be received at the proposed landfill without any treatment except possibly dewatering. Even with the acceptance of sludge, the proposed landfill presents little risk for the transmission of pathogens. Pathogens communicate disease only when a person is exposed to an effective dose and are better transmitted by direct contact or animal than air. Bacterial pathogens are themselves killed by wind, as well as sunlight, temperature, and humidity differentials, so the preferred means of air transmission would be aerosol versus gas. The record permits no findings as to the persistence of pathogenic viruses, protozoa, and parasitic worms. However, as noted above in connection with the land transmission of pathogens, the immediate application of lime and cover to the sludge will tend to prevent the release of effective doses of pathogens by air, as well. The last major class of pollutant that could be transmitted by air is heavy metals, such as mercury or lead. Although these metals produce a wide range of neurological diseases and generally interfere with cognition and behavior, Dr. Carpenter admitted that heavy metals were not as much of a concern as VOCs, presumably due to their resistance to vaporization. Even though transmission by air is not as tightly controlled as transmission by water or land, for the four reasons noted above, there is little risk of transmission by air--i.e., dust, aerosol, or gas--when the specific properties of likely pollutants are considered. In all but five respects, then, Republic has provided reasonable assurance that public health will not be endangered by pollutants released from the landfill by water, land, or air. First, to provide reasonable assurance concerning public health, the Permit needs a condition that prohibits spraying leachate during windy conditions, which DEP may define as it reasonably sees fit. As noted in the Conclusions of Law, this is a requirement in the rules and, due to its importance, should be restated explicitly in the Permit, which restates numerous other rule requirements. Second, to provide reasonable assurance concerning public health, the Permit needs more frequent monitoring of leachate water quality, at least at the frequency, as noted in the Conclusions of Law, set forth in the rules. Large volumes of untreated leachate will be recirculated through the landfill. Even if aerosol transmission is controlled, transmission by evaporation of some pollutants, although not the heavy metals, is possible. Also, pollutants are concentrated in recirculated leachate and thus the consequences of transmission into groundwater or surface water, however unlikely, become greater. At the same time, the action leakage rate is generous--to Republic, not the groundwater. At 100 gallons per acre per day, Republic is not required to report to DEP possible liner leakage until about 7300 gallons per day are lost to the surficial aquifer. Suitable for the detection of catastrophic failures associated with most sinkholes, this action leakage rate is too high to trigger action for small liner leaks. If Republic is to be allowed this much leakage into the groundwater, it must identify the leachate's constituents and their concentrations at least semi-annually. Third, to provide reasonable assurance concerning public health, the Application must extend the right of split testing to all of the parties in these cases, if DEP fails to exercise its right to take a split sample. The spraying of untreated leachate and generous limit applied to liner leakage before reporting and remedial action are required underscore the importance to public health of independent leachate testing. There is no reason to allow budgetary constraints or administrative oversight to preclude Petitioners and Intervenor, who are uniquely situated to suffer from the escape of excessive pollutants in the leachate, from providing, at their expense, this independent leachate testing. Fourth, to provide reasonable assurance concerning public health, the Permit needs to restate accurately the language of the rules concerning the extent of knowledge required of Republic, if it is to be liable for the acceptance of certain prohibited wastes. Fifth, to provide reasonable assurance concerning public health, the Permit needs to be modified to ensure that at least one spotter, whose sole responsibility is spotting, will be assigned to each working face while the landfill is receiving waste. Sinkholes The sinkhole issue arises in the geotechnical analysis of the sufficiency of the foundation to support the considerable loads of a landfill and also in the stability of the side slopes of the landfill. This analysis starts with consideration of the geology of the area, of which Republic's property is a part, and, among other things, the potential for sinkhole formation in the area. The Cedar Trail Landfill lies within the Bartow Embayment and along the eastern slope of the Lakeland Ridge of the Central Lake District Physiographic Province. This embayment is a large erosional basin partially backfilled with phosphatic sand and clayey sand of the Bone Valley Member. At this location, the top of the Floridan Aquifer is formed by Suwannee Limestone, which consists of white to tan, soft to hard, granular, porous, very fossiliferous limestone with interbedded dolomite. This rock unit is 110-140 feet thick. Atop the Suwannee Limestone sits the Hawthorne Group, which comprises the Arcadia Formation, at the base of which is the Nocatee Member, which is a relatively impermeable sand and clay unit. Atop the Nocatee Member is the Tampa Member, which consists of hard, dense, sandy, locally phosphatic, fossiliferous limestone. The top of this member, which is the top of the Arcadia Formation, is locally referred to as the "bedrock complex," which marks the lower limit of phosphate mining. Atop the Arcadia Formation, still within the Hawthorne Group, sits the Peace River Formation, which consists of phosphatic clayey sand and clayey sand. The lower portion of the Peace River Formation is a relatively impermeable, undifferentiated clayey unit locally known as "bedclay." The Bone Valley Member of the Peace River Formation is mined for phosphate and is locally known as "matrix." Atop of the Peace River Formation are undifferentiated surficial soils, typically consisting of silty sand, clayey sand, and some hardpan and organic soils. These materials are locally known as "overburden." Phosphate mining is prevalent in the area, including, as noted above, much or all of the Cedar Trail Landfill site. Strip mining for phosphate normally removes the entire surficial aquifer, just into the bedclay. Mined areas are then backfilled with overburden spoil soils, clay, waste clay, and sand tailings. After backfilling, the soil strata bear little resemblance to premining strata. Sinkholes are prevalent in the general area surrounding the Cedar Trail Landfill. A sinkhole is a surface depression varying in depth from a few feet up to several hundreds of feet and in area from several square feet to several acres. Sinkholes are typically funnel-shaped and open broadly upward. Sinkholes form when weakly acidic groundwater creates cavities in the calcium carbonate within limestone. Soils above these cavities erode into the cavities. In the area that includes the Cedar Trail Landfill, cover-collapse and cover- subsidence sinkholes predominate among sinkhole types. A cover-collapse sinkhole, which is typically steep- sided and rocky, forms when cohesive soils over a limestone cavity can no longer bridge the cavity under the weight of overlying soil and rock. At this point, the cohesive soils suddenly collapse into the cavity. These are more common in the part of the state in which the Cedar Trail Landfill is located. A cover-subsidence sinkhole occurs due to the gradual lowering of the rock surface as solutioning occurs in the subsurface rocks. This type of sinkhole develops as subsurface soluble rock is dissolved and overlying soils subside into the resulting shallow surface depressions. Regardless of the type of sinkhole, borings into sinkholes will reveal zones of very loose soil sediments that have washed downward into the cavernous voids within the bedrock. This very loose soil zone is called a raveling zone, which starts at the limestone layer, as the overlying soils begin to collapse into the solution features within the limestone. As the loosening works its way upward toward the surface, it eventually results in the subsidence of the ground surface and formation of a sinkhole. Considerable sinkhole activity has taken place in the immediate vicinity of Republic's property. Most visibly, a sinkhole formed in 2006 in 285-acre Scott Lake, 4.5 miles northwest of the landfill. This sinkhole drained the entire lake and destroyed several structures. The Florida Geological Service sinkhole database, which consists of anecdotal reports of sinkhole activity, some of which are unverified, includes 49 sinkholes within five miles of the proposed landfill. Two documented sinkholes have occurred within .17 mile of the landfill--one of which is reported to be 125 feet in diameter and 80 feet deep. Based upon the information contained in the preceding paragraph, Clint Kromhout, a professional geologist with the Florida Geological Survey, opined on August 23, 2009, that the potential for sinkhole formation "within the proposed site and surrounding area" is "low to moderate." Mr. Kromhout does not provide a definition of "low," but part of his opinion is shared by the Golder Report, which agrees that the sinkhole potential on the proposed site is "low." The potential for sinkhole formation in the general area surrounding the proposed landfill, as distinguished from the site itself, is at least moderate. In their Proposed Recommended Order, Republic and Intervenor necessarily concede: "All parties acknowledge that the proposed landfill site is in a general region that has a relatively high frequency of sinkholes as compared with the rest of the state of Florida." It is misleading to characterize the area surrounding the proposed landfill as of low potential for the formation of sinkholes, unless there is another category, like "nonexistent." But characterizing the sinkhole potential of the surrounding area as moderate is not determinative of the likelihood of sinkholes at the landfill's footprint, nor is a site-specific geotechnical investigation mooted by such a characterization. Rather, characterizing the sinkhole potential of the surrounding area as moderate dictates the intensity and scope of the ensuing geotechnical investigation, if the investigation is to provide reasonable assurance of the structural integrity of the proposed landfill. Acknowledging moderate potential for sinkhole formation in the surrounding area, Republic has appropriately relied on three geotechnical reports, including three sets of boring data. The final of these reports, the Hanecki Report, is based on the collection and analysis of boring data, as well as a review of the data and analysis contained in the two earlier geotechnical reports, the Ardaman Report and Golder Report. The boring data reveal that the proposed landfill site features four units. Nearest the surface is Unit 1, which is brown to dark brown, medium- to fine-grained sand with minor amounts of clayey silt. Unit 1 is 0-10 feet thick. Next down is Unit 2, which is tan to gray, medium- to fine-grained sand with increasing silty clay or clayey silt. Unit 2 is 5-10 feet thick and generally marks the upper limit of fine-grained, granular soils (i.e., clayed sands and silty sands). Unit 3 is orange brown to yellow brown, gray and tan silty clay to clayey silt or fine sand and silty clay. Unit 3 is 5-15 feet thick. Unit 4 is gray and tan clayey silt or silty clay with minor amounts of fine sand. This material is very stiff or very dense, and most borings terminated in this unit. The few borings that penetrated this unit suggest that it may consist of dolomitic sandy clays and silts and dolomitic limestone to depths greater than 100 feet below grade. Units 3 and 4 generally mark the upper limits of low permeability/low compressibility soils. The Hanecki investigation comprised two main steps. First, Hanecki retained a subconsultant to perform electrical resistivity imaging (ERI) along 100-foot-wide transects run across the site. Any anomalies revealed by the ERIs were to be followed by standard penetration test (SPT) borings, which permit soil testing at predetermined intervals, as well as a measure of the compressibility of the soils. Compressibility is measured during the soil-testing intervals, during which the drill bit is replaced by a soil sampler. The driller records the number of blows required for a 140-pound hammer falling 30 inches to produce 12 inches of penetration. The value is expressed in N-values, where N represents the number of such blows. Looser soils produce lower N values. Another important piece of information obtained during SPT boring is the partial or total loss of circulation fluid during drilling. While the drill is penetrating soil, a slurry circulates through the borehole to prevent the collapse of the sides of the hole. This slurry is recycled during drilling, but, if the drill encounters a void, all or part of the circulation fluid is lost. The ERI survey revealed no real anomalies because of a narrow range of resistance values. However, taking relatively small differences in resistivity as an anomalies, Hanecki identified 14 features of interest. At each of these locations, Hanecki performed an SPT boring. Because the ERI transects were unable to span the two onsite ponds, Hanecki added two locations for SPT borings adjacent to each side of each pond, for a total of four additional SPT borings. At the request of DEP, Hanecki added a nineteenth SPT boring at Golder site G-11, which had revealed low N-values during Golder's borings. Hanecki extended the borings into "refusal" quality soil, which was defined as soils requiring more than 50 blows of the 140-pound hammer to achieve six inches or less of penetration. All of Hanecki's SPT borings encountered very hard limestone. Among the most significant findings of Hanecki's borings, only one boring, G-11, experienced any circulation fluid loss, and this was estimated at 50 percent. However, it is more likely that this partial circulation fluid loss is due to loosely deposited sands than a void that might be indicative of conditions suitable for sinkhole formation. Not all circulation losses indicate voids that that will result in sinkhole formation. Also significant among Hanecki's findings is a clayey soil, or bedclay, at every SPT boring, which severely limits hydraulic recharge to the limestone. By impeding vertical migration of surface and shallow subsurface water to the limestone layer, this bedclay "greatly inhibits limestone erosion." This bedclay also supports the looser soils above the bedclay and thus prevents raveling, without which sinkholes cannot form. Two borings--G-11 and F3-1--lacked a layer of Unit 3 or 4 soil above the limestone, but Hanecki concluded that the Unit 2 layers above the limestone at these locations contained sufficient clay or clayey sand to serve the same functions of impeding the downward movement of groundwater and preventing the downward movement of loose soils. This conclusion appears reasonable because Unit 2 is the uppermost reach of the finer- grained materials, of which clays and silts are examples when compared to sands. There is obviously some variability in the distribution of finer- and coarser-grained materials within each occurrence of Unit 2 soils. Hanecki's findings indicated intervals of loose soils, sometimes at depth, which typically would suggest raveling zones. At the proposed location, though, these findings do not support raveling due to the underlying bedclay layer and the history of mining, which probably introduced looser soils typically found closer to the surface through the entire 40-foot depth of the mine cut. Based on these findings, the Hanecki Report concludes that, regardless of at least moderate potential for sinkhole potential in the area, the footprint of the proposed landfill has an acceptably low risk of sinkhole development to permit development of the proposed landfill. This is a reasonable conclusion because it is supported by the data collected by Hanecki and his reasoned analysis of these data. Hanecki's conclusion is also supported by the data and analysis contained in the Golder Report and Ardaman Report, which are based on an additional 84 SPT borings, post- reclamation. Only about 12 percent of these SPT borings reached the limestone, and they cover all of Republic's property, not merely the footprint of the proposed landfill. Even so, these borings confirm two important findings of the Hanecki Report. First, they produced data indicative of an extensive bedclay layer intact on Republic's property. Second, the Ardaman and Golder borings reveal only two or three instances of partial circulation loss that, like the sole occurrence of partial circulation loss in the Hanecki borings, are located on Republic's property, but outside the footprint of the proposed landfill. Republic has provided reasonable assurance that the site will provide an adequate foundation for the proposed landfill and sinkholes are unlikely to undermine the structural integrity of the proposed landfill.

The Issue The ultimate issue to be resolved in this proceeding is whether the Department of Environmental Regulation should issue a permit to Broward County authorizing construction of the proposed Cell 14 extension of the Broward County landfill located in the Town of Davie, Florida. Broward County and the Department of Environmental Regulation contend that Broward County has provided reasonable assurance that the proposed facility will meet the requirements of the Department's rules and regulations and not cause pollution in contravention of the Department's standards. The Town of Davie contends that the proposed facility will not meet the Department's requirements and will result in pollution in contravention of the Department's standards.
Findings Of Fact Broward County presently operates a landfill known as the Davie Landfill on a tract of land comprising 200 acres within the Town of Davie, Broward County, Florida. The existing sanitary landfill includes 13 cells which cover approximately 20 acres on the northeastern portion of the site. The landfill had an original design elevation of50 feet. The Department of Environmental Regulation, in a separate permitting proceeding, has authorized an increase to the height of the existing landfill to 90 feet. The permit authorizing increasing the height of the existing landfill has been challenged by the Town of Davie and is the subject of a separate proceeding before the Division of Administrative Hearings. The site which includes the landfill also has a sludge lagoon and trash landfill located in close proximity to the sanitary landfill. The sludge lagoon was used until sometime in 1981 for disposal of septic tank clean-out, sludges, grease trap waste, and wastewater treatments. The trash landfill was designed primarily for disposal of yard trash. The existing landfill has vertical side slopes of 3.5 to l. In other words, the height of the landfill increases along sides by i foot for every 3.5 feet traveled horizontally. Through this application, Broward County is seeking approval to expand its sanitary landfill by adding a proposed Cell 14. Cell 14 would constitute a Class I landfill since it will receive in excess of 20 tons of solid waste per day. The proposed Cell 14 would be constructed along the existing western face of Cells 1 through 13. It would ultimately be constructed to a height of 90 feet and would be capped with an impervious substance. The western side slope of the proposed cell would also be 3.5 to 1. Cell 14 would cover approximately 11 acres, bringing the total size of the sanitary landfill to just over 30 acres. With Cell 14, the sanitary landfill would continue to operate until approximately 1986. Containing leachate and preventing it from entering surface or ground waters is a most important consideration in determining whether to permit sanitary landfills. Leachate is water that has passed through refuse and been contaminated by the refuse. If significant amounts of leachate from Cell 14 enters into surface and ground waters, violations of the Department's water quality standards would be likely. Several features have been designed into Cell 14 to prevent introduction of leachate into surface and ground waters. The base of the cell would have a high density polyethylene liner to prevent percolation of Leachate that collects at the bottom of the cell into groundwater. A leachate collection system consisting of pipes and manholes has been devised. As leachate collects at the base of the cell, it will be dumped into tank trucks and carried to nearby wastewater disposal plants where it will be treated. A stormwater collection system has been designed so that initial stormwater runoff will be pumped to the leachate collection system and tested. If significant pollutants are contained in the stormwater runoff, it can continue to be pumped into the leachate collection system and ultimately removed to off-site treatment plants. If there are not significant pollutants in the runoff, runoff will be collected in a swale system and ultimately percolate into groundwater. Water that leaves the site in this manner is not likely to cause violations of Department of Environmental Regulation standards either in surface or ground waters. Numerous technological advances have occurred since Cells 1 through 13 of the Davie Landfill were designed and constructed. These cells have a designed-in leachate collection system. The system presently functions adequately, except that the liners under the earlier cells appear to be breaking down. It is apparent that the liner under Cells 1 through 4 has deteriorated to the extent that all leachate from these cells is not collected in the leachate collection system, but enters the groundwater below the landfill. Leachate from a landfill of this sort and magnitude that enters groundwater is likely to cause pollution in violation of the Department's standards. Leachate is presently entering the groundwater from Cells 1 through 4. The nature of the liner under the remaining original cells is not known. It is thought to be made of asphalt. Many forms of asphalt, obviously including the kind that was used to line Cells 1 through 4, are not capable of containing Leachate for an extended period of time. If the liner breaks down, the leachate collection system under all of the original cells will no longer function, and leachate will enter the groundwater, causing violations of Department of Environmental Regulation standards. There will not be an impervious liner between the existing cells of the Davie Landfill and the proposed Cell 14. It has been estimated that the cost of such a liner would be prohibitive. There will be limerock placed between the existing cells and the proposed cell; however, limerock is permeable. Some Leachate from Cell 14 will seep into the existing cells. Some of the leachate from the proposed Cell 14 that enters the existing Cells 1 through 4 will find its way into groundwater under the landfill. Leachate that enters the remaining cells will also find its way into groundwater if the liner under these cells breaks down as the liner under Cells 1 through 4 has broken down. If Leachate from the proposed Cell 14 enters groundwater under the site of the landfill, it is likely to cause pollution in violation of Department of Environmental Regulation standards. Groundwater in the area of the Davie Landfill flows generally from the northwest to the southeast. Some of the groundwater from the site of the sanitary landfill is likely to find its way into a canal which is located just to the south of the site. this is the C-11 Canal. If leachate from the proposed Cell 14 enters groundwater under the site of the landfill, it is likely to ultimately cause violations of Department of Environmental Regulation standards in the C-11 Canal. Except for the fact that the liners under the existing cells of the sanitary landfill are subject to deterioration, the leachate collection system can function appropriately. The leachate collection system for the proposed Cell 14 can also function without allowing introduction of leachate into surface and ground waters. The leachate collection systems utilize pipes that are presently buried under the existing landfill and will be further buried by the construction of Cell 14. The pipes that are presently being used, and are proposed to be used, are designed to withstand pressure greater than would be imposed on them. Furthermore, they are being placed in such a manner (surrounded by rock and utilizing ball joints) as to reduce the pressure imposed upon them. It is possible that one of the pipes could break and that leachate could thus escape from the Leachate collection system. This possibility is not a likely one, however, given the design parameters of the pipes and the nature of their installation. The fact that the leachate collection system for existing cells of the Davie Landfill would be buried under the proposed Cell 14 does not raise a significant danger that the system will break down. Again, the design parameters of the pipes and the nature of their installation render breakage unlikely. The sludge pit that is located just to the southwest of the sanitary landfill and the trash landfill that is located just to the south of the sanitary landfill offer potentially severe threats to the integrity of ground and surface waters on and off of the site. The sludge pit is a hazardous waste site. The trash landfill is not designed to prevent substances placed on the landfill from percolating into groundwater. It does not appear that construction of the proposed Cell 14 addition to the sanitary landfill would increase the risk of pollution that the sludge pit and trash landfill present. It does not appear that construction of the proposed Cell 14 would cause significant additional surface or ground water flows that would increase the risk of material from the sludge pit or the trash landfill from entering surface or ground waters. The applicant has failed to provide reasonable assurance that its proposed addition to the Davie Landfill will not result in violations of Department of Environmental Regulation standards contained in Chapters 17-3, 17- 4, and 17-7, Florida Administrative Code. While the proposed cell has been designed with appropriate liners and with an appropriate leachate collection system, its location abutting an existing landfill which does not have an adequate liner preventing percolation of leachate into groundwater increases the risk of that occurring. It appears that the only means of preventing or reducing that risk is either to close off the existing cells, or to place a liner between the existing cells and any addition in order to prevent flows of Leachate from new landfill activities into the existing cells.
