25 Pa. Code § 88.118 - Backfilling and grading: final slopes
(a) The final graded slopes shall approximate
premining slopes, or slopes approved by the Department based on consideration
of soil, rock formation, climate or other characteristics of the surrounding
area.
(b) Postmining final graded
slopes need not be uniform but shall approximate the general nature of the
premining topography.
(c) Cut and
fill terraces may be allowed on approval by the Department to conserve soil
moisture, ensure stability and control erosion on final graded slopes, if the
terraces are compatible with the approved postmining land use and are
substitutes for construction of lower grades on the reclaimed lands.
(d) Small depressions may be constructed, if
they:
(1) Are approved by the Department to
minimize erosion, conserve soil moisture or promote vegetation.
(2) Do not restrict normal access.
(3) Are not inappropriate substitutes for
lower grades on the reclaimed lands.
(e) All surface mining activities on slopes
above 20°, or on lesser slopes that the Department defines as steep slopes,
shall meet the appropriate provisions.
(f) All final grading, preparation of
overburden before replacement of soil or suitable vegetation support material
shall be conducted in a manner which minimizes erosion and provides a surface
for replacement of soil which will minimize slippage.
