25 Pa. Code § 87.110 - 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 the
following:
(1) Identifying, burying and
treating, when necessary, spoil that may adversely affect water quality if not
treated or buried.
(2) Preventing
water from coming into contact with acid-forming and toxic-forming spoil in
accordance with §
87.145 (relating to backfilling
and grading: covering coal and acid-forming and toxic-forming materials) and
other measures as required by the Department.
(b) Temporary storage of the spoil may be
approved by the Department upon a finding that storage will not result in any
risk of water pollution or other environmental damage. 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 placed on impermeable material and
protected from erosion and contact with surface water. Any discharge shall be
collected and treated to conform to §
87.102 (relating to hydrologic
balance: effluent standards).
