• PROTECTION OF HYDROLOGICAL BALANCE - RULE 2.05.6(3) The Bear Coal Company does not believe that any hydrologic consequences will result as part of the mining activities. A detailed drainage and sediment control program has been initiated to control all drainage from the affected area. An NPDES permit has been approved and all surface water discharge must meet the effluent limitations of that permit. The underground mining is not anticipated to affect any groundwater. As mentioned earlier, no water has been encountered in the Bear No. 2 and likewise the old workings of the Clark mine. The surface facilities of the Bear Coal Company should not pose any problem for contamination of surface water or water found in the alluvial material. A comprehensive alluvial (groundwater) monitoring program has been • initiated. Three shallow groundwater wells have been established and will be monitored on a continuing basis throughout the mining operations to determine any potential impacts on that groundwater. Following mining activities, the area will be graded, re-topsoiled and reseeded in accordance with the approved Reclamation Plan. Post-mining cover and productivity will be achieved to the satisfaction of the Division prior to any bond release. The sedimentation pond will remain until such time that runoff from the reclaimed area will meet the effluent limitations as established by the Division. Because of the planned depth of the mining, subsidence should be minimal and perhaps non-existent. An ongoing monitoring program for subsidence will be maintained throughout the life of the operation. No surface water degredation should occur even if minor subsidence does occur. • The Bear Coal Company will not continue its efforts to permit a coal conveyor system passing over the North Fork of the Gunnison River. Therefore, no concerns will arise from this potential system. If the -49-
