Colorado Division of Minerals and Geology (DMG) <br />• rules 2.05.6 and 4.20 require that "underground <br />mining activities shall be. planned and conducted so <br /> as to prevent subsidence from causing material <br /> damage to the surface...". Material damage is <br /> defined in Rule 2.05.6 with respect to subsidence <br /> as changes which prevent restoration of affected <br /> structures and with respect to renewable resource <br /> lands; changes which disrupt an aquifer, or a <br /> recharge area to an aquifer, which serves as a' <br /> beneficial use of water; or changes which prevent <br /> restoration of productivity for agricultural lands. <br /> Implementation of these regulations will minimize <br /> the impacts of subsidence. <br />vegetation <br />Direct Impacts- Some minimal impacts to vegetation <br />would result if subsidence occurs. <br />Indirect Impacts- No impacts have been identified. <br />Cumulative Impacts- No impacts have been <br />identified. <br />5. Wildlife <br />• Direct Impacts- Since the proposed action is for <br />subsurface mining, no direct impacts to big game <br />are anticipated. There are no anticipated impacts <br />to wildlife due to the possible subsidence that may <br />occur. <br />Indirect Impacts- None <br />Cumulative Impacts- The application indicates that <br />operations are intended to be continued at the same <br />production level. Truck traffic and human activity <br />would continue to affect big game species, <br />particularly during the winter months. <br />6. Land Use and Transportation <br />Direct Impacts- The proposed action would <br />facilitate development of coal on approximately <br />194.79 acres of federal coal. Development of the <br />coal would diminish federal interest in these <br />lands. Livestock grazing on these lands would not <br />be effected. <br />• 13 <br />
