NECESSITY, FUNCTION AND CONFORMITY:
				KRS
				224.10-100(19)(c), (24) and
				224.40-305
				authorize the cabinet to promulgate administrative regulations for the
				management, processing, and disposal of wastes.
				KRS
				224.40-305 requires that persons engaging in
				the management, processing, and disposal of solid waste obtain a permit. This
				administrative regulation establishes requirements for petroleum-contaminated
				soil treatment facilities.
Section 1.
			 Definitions.
(1) "Asphalt plant aggregate
			 dryer" means a low-temperature thermal desorption unit identical in design to a
			 countercurrent rotary dryer that does not have a secondary treatment chamber,
			 typically operates at a soil discharge temperature range from 300 degrees to
			 600 degrees Fahrenheit, and produces treated soil suitable for use as hot mix
			 asphalt aggregate only.
(2)
			 "Biopile" means a contained vessel or a lined and covered pile used for the
			 biological treatment of petroleum-contaminated soil.
(3) "Conveyor furnace" means a
			 low-temperature thermal desorption unit consisting of a flexible metal belt,
			 which conveys petroleum-contaminated soil though the heating chamber. Soil
			 agitators lift and turn the soil to enhance heat transfer. Organic vapors
			 exiting the chamber are destroyed in an afterburner.
(4) "Low-temperature thermal desorption"
			 means an ex-situ treatment technology that uses heat to physically separate
			 petroleum hydrocarbons from excavated soils that have been screened to remove
			 objects greater than two (2) inches in diameter. Low-temperature thermal
			 desorption units heat soils to temperatures sufficient to volatilize petroleum
			 hydrocarbons and can cause some hydrocarbons to completely or partially
			 decompose. Vaporized hydrocarbons can be additionally treated in a secondary
			 treatment chamber consisting of an afterburner, catalytic oxidation camber,
			 condenser, or carbon absorption unit.
(5) "Petroleum-contaminated soil" means silt,
			 sand, clay, gravel, or other earthen material; or asphalt, concrete, or
			 absorbent materials containing hydrocarbon concentrations above the levels
			 established in Section 6, Table 3 of this administrative regulation, but does
			 not exhibit a hazardous characteristic or is not a listed hazardous waste as
			 defined in 401 KAR Chapter 31.
(6)
			 "Petroleum-contaminated soil treatment facility" means a solid waste site or
			 facility where petroleum-contaminated soil is treated to reduce contaminant
			 concentrations to or below the levels established in Section 6, Table 3 of this
			 administrative regulation.
(7)
			 "Rotary dryer" means a low-temperature thermal desorption unit that is a
			 cylindrical metal reactor in which soil is brought into contact with heated
			 purge gases, raising the temperature of the soil to physically separate
			 petroleum hydrocarbons from the soil. Soil passing through the unit are lifted
			 and turned to ensure all soil particles are sufficiently heated to adequately
			 vaporize petroleum hydrocarbons out of the soil. Soil can pass through the unit
			 concurrently or countercurrently to the direction of the purge gas
			 flow.
(8) "Thermal screw" means a
			 low-temperature thermal desorption unit consisting of a series of augers that
			 convey, mix, and heat soil to volatilize petroleum hydrocarbons into a purge
			 gas stream, with the exiting organic vapors either collected or destroyed. Heat
			 is provided indirectly by hot oil or steam circulated through hollow stem
			 augers and the jacketed trough in which each auger rotates.
(9) "Wellhead protection area" means:
(a) The surface and subsurface area
			 surrounding a water well, well field, or spring, supplying a public water
			 system, through which pollutants are reasonably likely to move toward and reach
			 the water well, well field, or spring; or
(b) An area defined as a wellhead protection
			 area in a county water supply plan.
