§ 77.617. Mulching.
(a) Mulch shall be applied to regraded and topsoiled areas at rates adequate to control erosion, promote germination of seeds and increase the moisture retention of the soil, unless one of the following requirements are met:
(1) Seeding can be accomplished using a conventional agricultural farm drill.
(2) The approved postmining land use is for agricultural row crops.
(3) Annual grasses or small grains will be seeded immediately following final grading resulting in a quick vegetative cover which will provide adequate soil erosion control.
(4) The permittee can demonstrate that alternative procedures will achieve the standards for revegetation success of § 77.618 (relating to standards for successful revegetation).
(b) When required by the Department, mulches shall be mechanically or chemically anchored to the soil surface.
