Sec. 134.093.  BACKFILLING, GRADING, AND COMPACTING:  INSUFFICIENT OVERBURDEN.  (a)  This section applies to a surface coal mining operation:
(1)  that is carried out at the same location over a substantial period;
(2)  that transects the coal deposit;
(3)  in which the thickness of the coal deposit relative to the volume of the overburden is large;  and
(4)  for which the operator demonstrates that the overburden and other spoil and waste materials at a particular point in the permit area or otherwise available from the entire permit area are insufficient, considering volumetric expansion, to restore the approximate original contour.
(b)  Notwithstanding Section 134.092(a)(3), the operator, at a minimum, shall backfill, grade, and compact, where advisable, using the available overburden and other spoil and waste materials to attain the lowest practicable grade but not more than the angle of repose, to provide adequate drainage, and to cover the acid-forming and other toxic materials in order to achieve an ecologically sound land use compatible with the surrounding region.
