<br />MANAGEMENT <br /> <br />Post mining management of the underground mined areas at the New Elk Mine has involved minor <br />revegetation activities at the two shaft sites (now included in the Golden Eagle Permit). No other <br />management activities have occurred within the release area. Subsidence monitoring occurred as <br />a result of mining longwall panels in the late 1970s and early 1980s. No effects on post mining <br />land uses of this mining activity were noted. No monitoring of subsidence occurred in the room <br />and pillar mining area, however, no visual surface effects have been noted in these areas. <br />POST-MINING LAND USE <br />The underground mined areas are designated as rangeland or wildlife habitat. These land uses <br />have been maintained during muting activities. No effects of mining or possible subsidence have <br />been noted. <br />REVEGETATION SUCCESS <br />With exception of the Apache Canyon shaft locations which are now part of the Golden Eagle <br />Permit, no areas within the proposed release area have required revegetation. As a result, no <br />revegetation success standards apply to this release. <br />SURFACE AND GROUND WATER <br />The surface and ground water quantity and quality impact analysis is presented in the form of the <br />Annual Hydrology Reports. Generally, surface water within the proposed release area is of a <br />quality comparable to pre mine conditions and capable of supporting the designated post mining <br />land uses. Ground water levels and quality sampled from the mine workings has elevated <br />constituents, such as total dissolved solids, iron, and manganese, however, would also be capable <br />of supporting post mining land uses and is within the projections of the probable hydrologic <br />consequence presented in the Permit document. Monitoring stations located at the Apache Canyon <br />shafts located will remain in the monitoring program. <br />phasell1.626Uune 5, 1998 3 <br />
