BEAR COAL COMPANY 1993 AHR <br />Data supplied as per DMG letter dated 12/01/95 <br />Assessment of Hydrologic Impacts <br />The Division asks as part of the required assessment of <br />hydrologic impacts of mining during the year, why did the quality <br />of the alluvial wells improve for the 1993 sample? The 1993 AHR <br />indicates that AA1 and AA3 both saw a reduction in most of the <br />pertinent water quality except AA3 in which conductivity showed <br />an increase. The water quality did not really improve. The <br />reduction in most of the pertinent water quality parameter was <br />generally within expected ranges. <br />The 1993 AHR would assess the hydrologic impacts of mining during <br />the next year which would be 1994. Mining in 1994 was restricted <br />to the western portion of the reserve. Retreat mining was <br />performed in the First North Mains. The Third West Mains were <br />advanced. The Second North Mains were mined along with panels <br />14, 15, 16 b 17 (see Map 9A). Since the springs in Lone Pine <br />Gulch (G-26A, G-26B and CR-12) are protected from the impacts of <br />subsidence, no hydrologic impacts were anticipated or noted for <br />the mining performed in 1994. <br />
