2.04.7(1)(a) <br />• Except for the four wells (Lasater, Cargill, Watt and Rodgers) <br />mentioned previously, no potential effects are anticipated from <br />mining the "D" and "E" coal seams on other wells in the area. <br />Effects of mining the "D" and "E" coal seams will remove relative <br />pool quality water that would not be usable otherwise to wells <br />north of the mine permit area. Major effects on the usable ground- <br />water in the vicinity of the mining operation will be induced recharge <br />from the alluvial material into the coal seam. This will occur only in <br />those areas where coal seams directly underlay the base of the glacial <br />outwash alluvial material. This area is indicated on the isopach Map - <br />Alluvial Aquifer, 2.04.5-3. The induced recharge will occur directly <br />along the subcrop of each coal seam. Where the coal seam is covered <br />by a few ten's of feet of claystone and shale overburden, vertical <br />percolation of groundwater into the coal seam will be minimal. <br />Therefore, it is estimated that the induced recharge effect of mining <br />• <br /> <br />• REVISED Hay 8, 1981 60a j <br />.~-A .,.. <br />
