(a) Suitable mulch or other soil stabilizing practices shall be used on all regraded and topsoiled areas to control erosion, to promote germination of seeds, or to increase the moisture retention of the soil. The Commission may, on a case-by-case basis, suspend the requirement for mulch if the permittee can demonstrate that alternative procedures will achieve the requirements of §12.560 of this title (relating to Revegetation: Standards for Success) and do not cause or contribute to air or water pollution.
(b) Mulches shall be mechanically or chemically anchored to the soil surface to assure effective protection of the soil and vegetation when required by the Commission.
(c) Annual grasses and grains may be used alone, as in situ mulch, or in conjunction with another mulch, when the Commission determines they will provide adequate soil erosion control and will later be replaced by perennial species approved for the postmining land use.
(d) Chemical soil stabilizers alone or in combination with appropriate mulches may be used in conjunction with vegetative covers approved for the postmining land use.
