Section 19.8.20.2007 - TOPDRESSING: REDISTRIBUTION

A. After final grading and before the replacement of topdressing, regraded land shall be scarified or otherwise treated as required by the director to eliminate slippage surfaces and to promote root penetration. If the person who conducts the surface coal mining operations shows, through appropriate tests, and the director approves, that no harm will be caused to the topdressing and vegetation, scarification may be conducted after the placement of topdressing.

B. Topdressing shall be redistributed in a manner that:

(1) achieves an approximate uniform, stable thickness consistent with the approved postmining land uses, contours, and surface water drainage system;

(2) prevents excess compaction of topdressing; and

(3) protects the topdressing from wind and water erosion before and after it is seeded and planted.
