TITLE 401. ENERGY AND ENVIRONMENT CABINET - DEPARTMENT FOR ENVIRONMENTAL PROTECTION |
Chapter 45. Special Waste |
401 KAR 45:100. Landfarming and composting of special waste
-
Section 1. Applicability. The requirements in this administrative regulation apply to any person disposing of or treating special waste by landfarming or composting.
Section 2. Classifications of Special Waste Landfarming and Composting Sites or Facilities. A special waste landfarming or composting site or facility is classified as a Type A or Type B facility after the cabinet reviews the Notice of Intent filed pursuant to Section 3 of this administrative regulation. The classification is based on the type and quantity of sludge or other special waste to be accepted at the landfarm or composting site or facility. The following classifications are established:
(1) A Type A landfarm or composting facility is a site or facility that accepts Type A wastewater treatment sludge or other special waste. Type A wastewater treatment sludge is sludge with the following parameters:
Cadmium
Greater than 10 mg/kg;
Copper
Greater than 450 mg/kg;
Lead
Greater than 250 mg/kg;
Nickel
Greater than 50 mg/kg;
Zinc
Greater than 900 mg/kg.
(2) A Type B landfarm or composting facility is a site or facility that accepts Type B wastewater treatment sludge or other special waste. Type B wastewater sludge is sludge with the following parameters:
Cadmium
Less than or equal to 10 mg/kg;
Copper
Less than or equal to 450 mg/kg;
Lead
Less than or equal to 250 mg/kg;
Nickel
Less than or equal to 50 mg/kg;
Zinc
Less than or equal to 900 mg/kg.
The maximum amount of wastewater treatment sludge that may be processed by a Type B landfarm or composting site or facility is 250,000 gallons or 250 tons (dewatered) per calendar year. If the owner or operator is processing Type B sludge and exceeds this volume limitation, then the site or facility shall be classified as a Type A landfarm or composting facility. Unless otherwise required by the cabinet, an applicant for a Type B landfarming or composting permit shall be exempt from the requirements of publishing a public notice, the posting of financial assurance, the monitoring of groundwater, and postclosure care.
(3) One (1) time only disposal. An applicant for one (1) time only disposal of special waste by landfarming or composting methods shall submit an application for a Type B landfarming or composting facility unless otherwise directed by the cabinet.
(4) Other special waste. An application to landfarm or compost special waste other than municipal wastewater treatment sludge shall be classified using the parameters set forth in subsections (1) and (2) of this section and additional parameters based upon the source, chemical and physical characteristics of the waste, the volume of waste, and the waste potential for adverse impact on human health or the environment. After review of the notice of intent filed pursuant to Section 3 of this administrative regulation, the cabinet shall classify the site or facility as either a Type A or Type B landfarming or composting facility. The applicant shall comply with all requirements in this chapter for the designated type of landfarming or composting facility.
(5) A facility composting a Type A wastewater sludge may, at the discretion of the cabinet, be classified as a Type B facility depending upon the volume of special waste received, methods of composting and siting considerations.
(6) A special waste landfarm or composting site or facilities classification under this section shall be reevaluated based upon the annual analyses submitted under Section 6(19) or 9(5) of this administrative regulation. The cabinet may reassign a landfarming or composting site or facility classification based on this submittal and require the owner or operator of the landfarm or composting site or facility to modify the permit accordingly.
(7) Classification under this section shall be based on the average concentration of these metals in a minimum of two (2) consecutive samples taken no closer than thirty (30) days apart. Metal concentration values shall be determined on a dry weight basis. Analysis shall be accomplished by determining the heavy metal concentration of the undried sample (wet weight) and converting to dry weight using percent solids. The following formula shall be used: mg/L or mg/kg (wet weight) divided by (percent solids/100) = mg/kg dry weight. A single metal parameter shall be sufficient to require a sludge to be classified as Type A.
Section 3. Application Procedure for a Special Waste Landfarming or Composting Permit. (1) Notice of intent to apply. An applicant for a special waste landfarming or composting permit shall submit a notice of intent to apply as required under Section 8(1)(b) or (c) of 401 KAR 45:030. Upon review of the notice of intent to apply, the cabinet shall notify the applicant of the waste classification determination and designate the landfarming or composting facility as either a Type A or Type B facility. An applicant may be exempt from submitting a notice of intent prior to submitting the permit application required in subsection (2) of this section if the applicant is classifying itself as a Type A facility. However, the applicant is required to submit a notice of intent form with the permit application specified in subsection (2) of this section.
(2) Contents of landfarming or composting permit application. Upon determination of a waste classification, a person shall submit the designated permit application for a special waste landfarming or a composting facility as specified in Section 8(1)(b) or (c) of 401 KAR 45:030 to the cabinet. A landfarming application may include parcels of land that are not located contiguously.
(3) An applicant for a landfarming or composting facility permit shall comply with applicable requirements for a formal permit as specified in 401 KAR 45:030. An applicant for a Type A landfarming or composting facility shall also comply with the public notice requirement in 401 KAR 45:050, the financial assurance requirements of 401 KAR 45:080, the surface and groundwater requirements of 401 KAR 45:160, and the postclosure requirements of Section 4 of this administrative regulation.
(4) Upon examination of geological aspects and other relevant factors in the permit application by the cabinet, the applicant may be required to prepare a groundwater monitoring plan to include location and specifications of wells, monitoring parameters and monitoring schedules in accordance with 401 KAR 45:160. This plan shall be required for Type A landfarms or composting facilities.
(5) The cabinet shall not allow landfarming or composting practices that may present a threat to human health or the environment. The cabinet shall base a decision as to the land application or composting suitability of a particular special 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 30:031, the likelihood that waste constituents will 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.
Section 4. Closure and Postclosure of Landfarming and Composting Facilities. (1) An owner or operator permanently ceasing to accept waste at a Type A or Type B special waste landfarming or composting site or facility shall submit to the cabinet a closure report that includes:
(a) The results of final soil samples taken in accordance with the construction/operation permit within eighteen (18) months following the last application of waste;
(b)1. Landfarming sites or facilities shall submit a historical summary of all landfarming, by subplot, showing the allowable and actual rates of special waste application, heavy metals and nitrogen, incorporating the annual landfarming review as set forth in Section 6(19) of this administrative regulation; or
2. Composting sites or facilities shall prepare a historical summary of composting activities at the site incorporating the annual composting review report as set forth in Section 9(5) of this administrative regulation.
(c) A certification from the owner or operator that the site or facility is closed and is in compliance with 401 KAR 30:031; and
(d) Any additional information required by the cabinet in the original landfarming or composting permit.
