When the reclamation plan calls for resoiling, coarse and hard mining waste shall be leveled and covered with a layer of finer material or weathered waste. A soil layer shall then be placed on this prepared surface. Surface mines that did not salvage soil during their initial operations shall attempt, where feasible, to upgrade remaining native materials. The use of soil conditioners, mulches or imported topsoil shall be considered where revegetation is part of the reclamation plan and where such measures appear necessary. Areas adjacent to mined lands shall not be stripped of their topsoil for proposes of reclaiming mined lands. No usable groundwater aquifer shall be reclaimed with nonporous materials such as clay, but the aquifer shall be restored with materials suitable for water retention.
