      RELATES TO: KRS 224.01, 224.10, 224.40, 224.43, 224.70, 224.99

      STATUTORY AUTHORITY: KRS 224.10-100

      NECESSITY, FUNCTION, AND CONFORMITY: KRS 224.10-100 and the waste management provisions of KRS Chapter 224 require the Natural Resources and Environmental Protection Cabinet to adopt administrative regulations for the disposal of solid waste. This chapter establishes standards for solid waste sites or facilities. This administrative regulation sets forth the permit application requirements and general design and operating requirements for landfarming facilities, composting, and sludge giveaway programs.

 

      Section 1. Applicability. (1) The requirements in this administrative regulation apply to any person disposing of solid waste by landfarming and composting.

      (2) The cabinet shall not permit the land application of a solid waste that may present a threat to human health and the environment. The land application suitability of solid wastes shall be evaluated by the cabinet on a case-by-case basis. The applicant shall submit a request for a determination of waste classification with the submittal of a notice of intent to apply. The cabinet may base a decision as to the land application suitability of a particular waste upon the ability of the waste to biodegrade in the environment, the potential for the waste to be managed in a manner consistent with 401 KAR 47:030, the likelihood that waste constituents shall contaminate surface water or groundwater, the potential for nuisances from odors or unsightly conditions, and the potential for the waste to harm human health or the environment.

      (a) Municipal water treatment sludges, municipal wastewater treatment sludges, or food service industry wastes shall be classified according to the maximum dry weight concentration of heavy metals based on the average concentration of metals in a minimum of two (2) consecutive samples taken no closer than thirty (30) days apart. The cabinet may deny the landfarming of a solid waste based upon health considerations in addition to the presence in the waste of excessive concentration of the five (5) heavy metals listed below. The sludges shall be placed in classes based on the concentration of the following heavy metals:

      1. Cadmium;

      2. Copper;

      3. Lead;

      4. Nickel; and

      5. Zinc.

      (b) Sludges or solid wastes other than municipal water treatment sludges, municipal wastewater treatment sludges, or food services industry solid wastes shall be classified using additional parameters based upon the source, chemical and physical characteristics of the waste and their potential for adverse impact on human health or the environment.

      (3) The concentration for heavy metals in each class of sludge or solid waste shall be those indicated in Table 1 of this subsection. A single metal parameter shall be sufficient to require a solid waste to be classified as Class II or III.

      (6) A landfarming permit may be issued based upon the information submitted in the application for solid wastes classified as Class II or III.

      (7) Solid waste heavy metal concentration values are determined on a dry weight basis. Analysis shall be accomplished by determining the heavy metal concentration of the undried sample and determining the heavy metal content using the solids content of the original sample and computing the heavy metals content of the sludge on a dry weight basis. Results of the laboratory determination shall include the solids content, the wet weight and dry weight content when they are submitted to the cabinet.
