Neither will it put to use processed water <br />during the normal mining operations. The mine is located approximately 70 feet <br />above the water table and the formation being mined is not active as an , <br />aquifer. Therefore, BLUE FLAME COAL COMPANY will not create any impact on the <br />sub-surface hydrologic balance. <br />MINE SITE SURFACE HYDROLOGY: <br />BLUE FLAME COAL MINE will have little to no impact on the grow <br />system and a slight impact on the surface hydrology. Proposed mining <br />upper Menefee coal seam will not disrupt aquifers, streams, or the wa <br />(upslope areas of permit area). <br />The mining bench is located in the upper reaches of the H <br />drainage system. The diversion ditches, sedimentation ponds, and <br />structures are depicted on the Mine Surface Map and Hydrology Map. <br />~ water ~~; ~ ~ <br />Ln this <br />~r shed I <br />f• <br />;: ~;. <br />e. <br />~ r <br />y ~'~;Y l <br />~ Gulch'.: ira~~ <br />. ~ TJ .yvu+,~.

See <br />Hydrology Map. <br />The disturbed acreage is limited to 4.] acres upon which the current <br />surface facilities are constructed. Natural drainage over this area is to the <br />North on a slope of less than 6$. Little or no top soil remains on the mining <br />bench. Historically, the mining of coal at this site has spanned thirty years; <br />no top soil was ever saved or stored. One sediment pond, North of the mine <br />bench and adjacent to the meadow will contain water and sediment run-off from <br />the disturbed surface. <br />
