NECESSITY, FUNCTION, AND CONFORMITY: KRS Chapter 224 requires the cabinet to adopt administrative regulations for the management, processing or disposal of wastes. KRS 224.40-305 requires persons who establish, construct, operate, maintain or permit the use of a waste site or facility to obtain a permit. This chapter establishes the permitting standards for special waste sites or facilities, and the standards applicable to all special waste sites or facilities. This administrative regulation sets forth the technical and operating requirements for special waste landfills.
Section 1. Design Requirements. The engineering design for a special waste landfill shall demonstrate compliance with 401 KAR 30:031 and the siting standards of 401 KAR 45:130 considering the following:
(1) The physical and chemical characteristics of the waste, including compatibility of the waste with the liner, if required; cover materials, if required; and water that may come in contact with the waste;
(2) Volume of waste;
(3) The climatic conditions in the area;
(4) The permeability of the liner material, if required. The liner shall assure containment of the waste on site and compliance with 401 KAR 30:031;
(5) The properties of the soil underlying the facility;
(6) Hydrogeologic characteristics of the site including quality, quantity, current use, and direction of groundwater flow;
(7) The design of the facility leachate control system, run-off control system, and gas migration control, if required, as it relates to the physical and chemical characteristics of the waste, the climatic conditions of the specific location, the volume of leachate and contaminated run-off collected at the facility;
(8) The proximity of the facility to surface water and groundwater;
(9) The potential for gas emissions and odors; and
(10) Any additional requirements specified by the cabinet.
Section 2. Construction Quality Control Plan. (1) An applicant for a special waste landfill permit shall submit a construction quality control plan conforming to Section 4 of this administrative regulation containing the following elements:

(2)(a) The construction quality control plan shall provide assurance that the layers of the homogeneous low permeability soil liners, if required, are compacted using nonvibratory compactors with full depth penetrating feet with a minimum of six (6) passes per soil layer. The compacter ballast shall be varied to prevent reaching the desired proctor density within less than six (6) passes. The foot length shall be one (1) inch longer than the loose soil layer thickness.
(b) Smooth rollers may be used at the end of each work period to seal the surface from rain infiltration.
Section 3. Operating Requirements. (1) The owner or operator of a special waste landfill shall operate the facility in accordance with the requirements of KRS Chapter 224, the requirements of this chapter, the conditions of the special waste landfill permit issued by the cabinet, and the operational plan filed with and approved by the cabinet.
(2) The owner or operator of a special waste landfill shall operate the facility in such a manner to ensure compliance with 401 KAR 30:031.
(3) The owner or operator of a special waste landfill shall inspect the site and operation at a sufficient frequency to ensure compliance with 401 KAR 30:031.
(4) The owner or operator of a special waste site or facility that is open to the public shall have a sign located at the entrance that indicates the landfill name, the names of the owner and the operator, the hours that the landfill is accepting wastes, the permit number, the contact person, and the emergency telephone number.
(5) One (1) copy of the permit application shall be returned to the permittee. The permit with all applicable conditions shall be conspicuously displayed at all special waste sites or facilities with a formal permit for the duration of the permit period. A copy of the approved application, including plans, shall be available at the site, or at a location approved by the cabinet.
(6) Records and reports shall be maintained and submitted in accordance with the requirements of Section 4 of this administrative regulation and Section 1(8) of 401 KAR 45:140.
(7) The cabinet may place additional requirements on the owner or operator of a special waste landfill if necessary to ensure compliance with 401 KAR 30:031.
Section 4. Special Waste Landfill Recordkeeping and Reporting. An applicant for a special waste landfill permit shall submit plans for a recordkeeping and reporting system. The plan shall meet the following requirements:
(1) Surface water and groundwater samples shall be collected and analyzed according to 401 KAR 45:160 and the following criteria:
(a) Samples and measurements taken for the purpose of monitoring shall be representative of the monitored activity.
(b) The owner or operator shall retain records of all monitoring information, copies of all reports required by the permit, and records of all data used to complete the application for the permit, for a period of at least three (3) years from the date of the sample, measurement, report, certification, or application. This period may be extended by request of the cabinet at any time. In addition, the owner or operator shall maintain records from all groundwater monitoring wells and associated groundwater surface evaluations, for the active life of the facility, and for the closure care period as well.
(c) Records of monitoring information shall include:
1. Date, exact place, and time of sampling or measurements;
2. Individual who performed the sampling or measurements;
3. Date analyses were performed;
4. Individual who performed the analyses;
5. Analytical techniques or methods used; and
6. Results of such analyses.
(2) A summary of the monitoring information shall be submitted to the cabinet semiannually.
(3) If the owner or operator is conducting surface water and groundwater monitoring that meets the requirements of this chapter as part of a permit other than the special waste permit, certified copies of records and reports may be submitted to the cabinet rather than conducting and maintaining duplicative monitoring requirements.
Section 5. Closure and Postclosure Requirements. (1) A special waste landfill shall be closed in a manner that complies with 401 KAR 30:031. The owner or operator of a special waste landfill shall submit a closure plan that includes a closure design as specified in subsection (2) of this section, a closure cost estimate in accordance with Section 2 of 401 KAR 45:080, a narrative discussing the closure plan's conformance with 401 KAR 30:031 and a schedule for implementation of the plan.
