Alabama Administrative Code › Title 335 - ALABAMA DEPARTMENT OF ENVIRONMENTAL MANAGEMENT › LAND DIVISION - SOLID WASTE PROGRAM › Chapter 335-13-15 - STANDARDS FOR THE DISPOSAL OF COAL COMBUSTION RESIDUALS IN LANDFILLS AND SURFACE IMPOUNDMENTS › Section 335-13-15-.02 - Definitions

Current through Register Vol. 42, No. 9, June 28, 2024
The following definitions apply to this chapter. Terms not
				  defined in this chapter have the meaning given in
				  335-13-1-.03
(1) Acre foot - the volume of one acre of
				surface area to a depth of one foot.
(2) Active facility or active electric
				utilities or independent power producers - any facility subject to the
				requirements of this chapter that is in operation on October 19 015. An
				electric utility or independent power producer is in operation if it is
				generating electricity that is provided to electric power transmission systems
				or to electric power distribution systems on or after October 19, 2015. An
				off-site disposal facility is in operation if it is accepting or managing CCR
				on or after October 19, 2015.
(3)
				Active life or in operation - the period of operation beginning with the
				initial placement of CCR in the CCR unit and ending at completion of closure
				activities in accordance with
				335-13-15-.07(3).
(4) Active portion - that part of the CCR
				unit that has received or is receiving CCR or non-CCR waste and that has not
				completed closure in accordance with
				335-13-15-.07(3).
(5) Aquifer - a geologic formation, group of
				formations, or portion of a formation capable of yielding usable quantities of
				groundwater to wells, springs or waters of the state.
(6) Area-capacity curves - graphic curves
				which readily show the reservoir water surface area, in acres, at different
				elevations from the bottom of the reservoir to the maximum water surface, and
				the capacity or volume, in acre-feet, of the water contained in the reservoir
				at various elevations.
(7) Areas
				susceptible to mass movement - those areas of influence (i.e., areas
				characterized as having an active or substantial possibility of mass movement)
				where, because of natural or human-induced events, the movement of earthen
				material at, beneath, or adjacent to the CCR unit results in the downslope
				transport of soil and rock material by means of gravitational influence. Areas
				of mass movement include, but are not limited to, landslides, avalanches,
				debris slides and flows, soil fluctuation, block sliding, and rock
				fall.
(8) Beneficial use of CCR -
				the CCR meet all of the following conditions:
(a) The CCR must provide a functional
				benefit;
(b) The CCR must
				substitute for the use of a virgin material, conserving natural resources that
				would otherwise need to be obtained through practices, such as
				extraction;
(c) The use of the CCR
				must meet relevant product specifications, regulatory standards or design
				standards when available, and when such standards are not available, the CCR is
				not used in excess quantities; and
(d) When unencapsulated use of CCR involves
				placement on the land of 12,400 tons or more in non-roadway applications, the
				user must demonstrate and keep records, and provide such documentation upon
				request, that environmental releases to groundwater, surface water, soil and
				air are comparable to or lower than those from analogous products made without
				CCR, or that environmental releases to groundwater, surface water, soil and air
				will be at or below relevant regulatory and health-based benchmarks for human
				and ecological receptors during use.
