Rules. A discussion of the post-mining land-uses can be found beginning on page 2.05-123, and on page <br />2.05-181 of permit Volume I. <br />XIII. Protection of Fish, Wildlife and Related Environmental Values <br />Twentymile Coal Company evaluated the mine plan expansion area for threatened and endangered <br />species. The mining area is at an elevation above that for habitat defined for Ute lady's tresses orchid. <br />The permit area is below the elevation expected for Boreal toad and lynx. A raptor survey was conducted <br />on areas projected for subsidence of Middle Creek. No active nesting sites were identified along the <br />proposed affected area of Middle Creek, and no Bald eagles were observed in the survey area. <br />X1V. protection of Underground Mining <br />No active surface mining activities are taking place in the immediate vicinity of the Foidel Creek Mine. <br />No specific approvals are granted under this section. <br />XV. Subsidence Control <br />The applicant has predicted that no material damage will result from subsidence. However, numerous <br />structures exist above the mining area. The applicant has presented a subsidence control plan to repair or <br />mitigate damage caused by subsidence for each of the existing structures. Details regarding the subsidence <br />control plan may be found in the approved permit. A brief summary of the subsidence control measures <br />for each structure follows. <br />Counri Road No. 33 <br />When daily monitoring reveals that the asphalt road surface has buckled or been damaged due to <br />subsidence, TCC will temporarily repair the surface using gravel. Once subsidence monitoring indicates <br />that subsidence has ceased, a permanent asphalt overlay or patch will be applied to the damaged road <br />section. This method has successfully been employed during the mining of Longwall panels 9R, 8R, 7R, <br />6R and SR in the Eastern Mining District. Twentymile Coal Company re-paved segments of Routt <br />County Road No. 33 in the fall of 1999, that had experienced damage due to subsidence of Longwall <br />Panels SR and 6R. <br />Southern Pacific Railroad <br />When daily monitoring indicates that the track is damaged or the grade has changed, a slow speed <br />restriction will be instituted. Re-leveling and repair of the track occurred in accordance with mitigation <br />plans required by Southern Pacific Railroad. <br />Havden-Gore Pass Powerline <br />When daily monitoring reveals structural tower damage, TCC will notify power repair crews to stabilize <br />and/or repair the damage. TCC will also notify the utility 30 days prior to undermining, in addition to the <br />Division requirement of 6 months notification of undermining. TCC representatives have held discussions <br />with the utility company and have indicated to DMG that re-routing capabilities and system redundancy <br />will prevent end line user power loss. Ground fault interruption capabilities are also in place to prevent a <br />downed line from remaining live if it were to fall to the ground or across County Road No. 33. <br />Twentymile Coal Company submitted a letter that confirms that end user power would not be interrupted. <br />This letter has been incorporated into the permit document in exhibit 7D-I. The powerline was subsided <br />C:UHB1C820561RN03\R N03FI ND.doc <br />25 <br />
