401 KAR 45:100.Landfarming and composting of special waste.

Section 1.

Applicability.

(1)

The requirements in this administrative regulation apply to any person disposing of or treating special waste by:

(a)

Composting; or

(b)

Landfarming of special wastes that are not biosolids.landfarming or composting.

(2)

Landfarming of biosolids shall be regulated in accordance with 401 KAR 45:105.

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 application filed pursuant 401 KAR 45:030 Section 8(1)(b).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:
CadmiumGreater than 10 mg/kg;
CopperGreater than 450 mg/kg;
LeadGreater than 250 mg/kg;
NickelGreater than 50 mg/kg;
ZincGreater 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:
CadmiumLess than or equal to 10 mg/kg;
CopperLess than or equal to 450 mg/kg;
LeadLess than or equal to 250 mg/kg;
NickelLess than or equal to 50 mg/kg;
ZincLess 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)

An application to landfarm biosolids shall meet the requirements of 401 KAR 45:105.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)

 

(a)

Classification under this section shall be based on the average concentration of these metals, listed in subsection (1) and (2) of this section, 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.

(b)

A single metal parameter shall be sufficient to require a sludge to be classified as Type A.

Section 3.
