Mine dewatering definition

Mine dewatering means removal of water from areas where surface mining or quarrying activities are being conducted. These mining activities include: a) the surface extraction of clay, bauxite, sand, gravel, soil, shale or other materials for commercial purposes; b) removing the materials over a coal seam, before recovering the coal; c) removing of stone from an open pit or quarry.

Mine dewatering means any water that is impounded or that collects in the mine and is pumped, drained or otherwise removed from the mine through the efforts of the mine operator. For sand and gravel mines and/or industrial sand mines, this term shall also include wet pit overflows caused solely by direct rainfall and ground water seepage. However, if a mine is also used for treatment of mine process generated wastewater, discharges of commingled water from the mine shall be deemed discharges of mine process generated wastewater.
