§ 90.302. Definitions.
The following words and terms, when used in this subchapter, have the following meanings, unless the context clearly indicates otherwise:
Abatement plan--Any individual technique or combination of techniques, the implementation of which will result in reduction of the baseline pollution load. Abatement techniques include, but are not limited to: addition of alkaline material, special plans for managing toxic and acid-forming material, regrading, revegetation and relocating coal refuse to a coal refuse disposal area that includes systems to prevent adverse impacts to surface and groundwater and to prevent precipitation from contacting the coal refuse.
Actual improvement--The reduction of the baseline pollution load resulting from the implementation of the approved abatement plan; except that any reduction of the baseline pollution load achieved by water treatment may not be considered as actual improvement. Treatment approved by the Department of the coal refuse before, during or after placement in the coal refuse disposal area is not considered to be water treatment.
Baseline pollution load--The characterization of the pollutional material being discharged from or on the pollution abatement area, described in terms of mass discharge for each parameter deemed relevant by the Department, including seasonal variations and variations in response to precipitation events. The Department will establish in each authorization the specific parameters it deems relevant for the baseline pollution load, including, at a minimum, iron and acid loadings.
Best professional judgment--The highest quality technical opinion forming the basis for the terms and conditions of the treatment level required after consideration of all reasonably available and pertinent data. The treatment levels shall be established by the Department under sections 301 and 402 of the Federal Water Pollution Control Act (33 U.S.C.A. §§ 1311 and 1342).
Best technology--Measures and practices which will abate or ameliorate, to the maximum extent possible, discharges from or on the pollution abatement area. These measures include engineering, geochemical or other applicable practices.
Coal refuse disposal activities--The storage, dumping or disposal of any waste coal, rock, shale, slurry, culm, gob, boney, slate, clay, underground development wastes, coal processing wastes, excess soil and related materials, associated with or near a coal seam, that are either brought above ground or otherwise removed from a coal mine in the process of mining coal or are separated from coal during the cleaning or preparation operations. The term does not include the removal or storage of overburden from surface mining activities.
Excess soil and related material--Rock, clay or other material located immediately above or below a coal seam and which is extracted from a coal mine during the process of mining coal. The term does not include topsoil or subsoil.
Pollution abatement area--The part of the permit area that is causing or contributing to the baseline pollution load. The term includes adjacent and nearby areas that must be affected to bring about significant improvements of the baseline pollution load and may include the immediate locations of the discharges.

(b) The operator shall treat the preexisting discharges that are not encountered during coal refuse disposal activities or implementation of the abatement plan to comply with the effluent limitations established by best professional judgment. The effluent limitations established by best professional judgment may not be less than the baseline pollution load. If the baseline pollution load, when expressed as a concentration for a specific parameter, satisfies the effluent limitation in § 90.102 for that parameter, the operator shall treat the preexisting discharge for that parameter to comply with either effluent limitations established by best professional judgment or the effluent limitations in § 90.102.
(c) For purposes of subsections (a) and (b), the term ''encountered'' may not be construed to mean diversions of surface water and shallow groundwater flow from areas undisturbed by the implementation of the abatement plan that would otherwise drain into the affected area, as long as the diversions are designed, operated and maintained under § 90.104(b)--(h) (relating to hydrologic balance: diversions).
(d) An operator required to treat preexisting discharges will be allowed to discontinue treating the discharges under subsection (b) when the operator affirmatively demonstrates the following to the Department's satisfaction:

(4) The operator did not cause or allow additional surface water pollution or groundwater degradation by reaffecting the pollution abatement area.
(e) If after discontinuance of treatment of discharges under subsection (d) the discharges fail to meet the effluent limitations established by subsection (b), the operator shall reinstitute treatment of the discharges under subsection (b). An operator who reinstitutes treatment under this subsection will be allowed to discontinue treatment if the requirements of subsection (d) are met.
