25 Pa. Code § 88.100 – Hydrologic balance: acid-forming and toxic-forming spoil.

(a) Drainage from acid-forming and toxic-forming spoil into groundwater and surface water shall be avoided by:
1. (1) Identifying, burying and treating, where necessary, spoil which, in the judgment of the Department, may be detrimental to vegetation or may adversely affect water quality if not treated or buried.
2. (2) Preventing water from coming into contact with acid-forming and toxic-forming spoil in accordance with § 88.119 (relating to backfilling and grading: covering coal and acid-forming and toxic-forming materials) and other measures as required by the Department.
3. (3) Burying or otherwise treating all acid-forming or toxic-forming spoil as soon as practical after it is first exposed on the mine site. Storage shall be limited to the period until burial or treatment first becomes feasible. Acid-forming or toxic-forming spoil to be stored shall be protected from erosion and contact with surface water. Any discharge shall be collected and treated to conform to § 88.92 (relating to hydrologic balance: effluent standards).

The provisions of this § 88.100 adopted December 19, 1980, 10 Pa.B. 4789, effective July 31, 1982, 12 Pa.B. 2382.
