predicts the impacts of a small part of the discharges as seepage from the coal seams' <br />subcrop beneath the Williams Fork River. This seepage would amount to only a few <br />gpm (permit page 2.05-46 says 33 gpm using in that worst-case analysis an <br />unreasonably high hydraulic conductivity value for the coals of 2.5 ft./day). The fate <br />of the remaining several hundred gpm discharges should be predicted in the PHC. <br />Please include any expected water quality changes caused by the water contacting <br />materials disposed in portal entries. <br />d. Predicted inflows from Middle Sandstone into planned Eseam-to-H seam rock <br />slopes. Please add to the PHC a prediction of the inflow rate from the Middle <br />Sandstone into the planned E-to-H seam rock slopes that will occur after the <br />potentiometric surface recovers in the Middle Sandstone following mining. It is <br />important to quantify this inflow because if it is substantial, then it could substantially <br />add to the mines' post-mining inflow prediction. <br />Eagle No. 5 and 9 Mines Page 8 February 13, 2001 <br />Midterm Review <br />
