Ill. Admin. Code tit. 62, § 1816.104 - Backfilling and Grading: Thin Overburden

In surface coal mining which is carried out at the same location over a substantial period of time where the operation transects the coal deposit and where the thickness of the coal deposit relative to the thickness of the overburden is large and where the operator demonstrates that the spoil and other waste materials available from the entire permit area are insufficient, giving due consideration to volumetric expansion, to restore the disturbed area to its approximate original contour, the operator shall, at a minimum:

a) Use all available spoil and waste materials to attain the lowest practicable grade, but not more than the angle of repose; and

b) Meet the requirements of Sections 1816.102(a)(2) through 1816.102(j).
