NECESSITY, FUNCTION, AND CONFORMITY:
				KRS 350.028(1),
				(5), and
				350.465(2)
				authorize the cabinet to promulgate administrative regulations relating to
				surface and underground coal mining operations. This administrative regulation
				establishes definitions for terms used in 405 KAR Chapter 18. This
				administrative regulation differs from federal regulations by including the
				definition of "angle of draw". This definition is necessary to determine areas
				subject to subsidence requirements and to comply with the intent of federal
				regulations.
Section 1. Definitions.
(1) "Acid drainage" means water with a pH of
			 less than six and zero-tenths (6.0) and in which total acidity exceeds total

			 (.90718 metric ton).
(117)
			 "Topsoil" means the A and E soil horizon layers of the four (4) master soil
			 horizons.
(118) "Toxic-forming
			 materials" means earth materials or wastes that, if acted upon by air, water,
			 weathering, or microbiological processes, are likely to produce chemical
			 conditions in soils or water that are detrimental to biota or uses of
			 water.
(119) "Toxic mine drainage"
			 means water that is discharged from active or abandoned mines or other areas
			 affected by coal exploration or surface coal mining and reclamation operations,
			 which contains a substance that through chemical action is likely to kill,
			 injure, or impair biota commonly present in the area that might be exposed to
			 it.
(120) "Transfer, assignment, or
			 sale of permit rights" means a change in ownership or other effective control
			 over the right to conduct surface coal mining operations under a permit issued

			 waste coal, shale, claystone, siltstone, sandstone, limestone, or similar
			 materials that are extracted from underground workings in connection with
			 underground mining activities.
(123) "Underground mining activities" means a
			 combination of:
(a) Surface operations
			 incident to underground extraction of coal or in situ processing, including
			 construction, use, maintenance, and reclamation of roads, aboveground repair
			 areas, storage areas, processing areas, and shipping areas; areas upon which
			 are sited support facilities including hoist and ventilating ducts; areas
			 utilized for the disposal and storage of waste; and areas on which materials
			 incident to underground mining operations are placed; and
(b) Underground operations such as
			 underground construction, operation, and reclamation of shafts, adits,
			 underground support facilities; in situ processing; and underground mining,
			 hauling, storage, and blasting.
(124) "Undeveloped land or no current use or
			 land management" means land that is undeveloped or, if previously developed,
			 land that has been allowed to return naturally to an undeveloped state or has
			 been allowed to return to forest through natural succession.

			 Environmental Protection Agency.

			 consisting of any material other than coal waste and organic material that is
			 placed in a valley where side slopes of the existing valley measured at the
			 steepest point are greater than twenty (20) degrees or the average slope of the
			 profile of the valley from the toe of the fill to the top of the fill is
			 greater than ten (10) degrees.

			 means:
(a) Listed or proposed endangered or
			 threatened species of plants or animals or their critical habitats listed by
			 the Secretary of the Interior under the Endangered Species Act of 1973, as

			 upper surface of a zone of saturation, where the body of groundwater is not
			 confined by an overlying impermeable zone.
(129) "Water transmitting zone" means a body

			 considered to function as a single hydraulic medium for the flow of
			 groundwater. (130) "Wetland" means land that has a predominance of hydric soils
			 and that is inundated or saturated by surface or groundwater at a frequency and

			 saturated soil conditions.
(a) "Hydric soil"
			 means soil that, in its undrained condition, is saturated, flooded, or ponded
			 long enough during a growing season to develop an anaerobic condition that
			 supports the growth and regeneration of hydrophytic vegetation.

			 growing in:
1. Water; or
2. A substrate that is at least periodically
			 deficient in oxygen during a growing season as a result of excessive water
			 content.
