Summary drilling occurred, cattle would likely be displaced • during the construction of the roads and drainage wells. Subsidence would not affect recreational opportunities. It is likely that NTSPc 711 would be upgraded if drilling equipment needed to access the area. Surface use could cause game to move out of the area, and reduce the hunting opportunity. There would be no change to the Recreation Opportunity Spectrum (ROS) of semi-primitive motorized recreation. Water conveyance facilities, ditch rider's cabin, and flume may be subsided. Structural damage is considered possible with a low to moderate likelihood of occurring, and is considered reparable. The degree of damage would depend on timing of when subsidence occurred. Alternative C Effects would be the same as Alternative E. Preventing subsidence of Deep Creek would prevent subsidence of the flume, so it would not be affected. Roads, Trills arn-I Reaffiess Areas Alternative A There would be no mining-related effect on existing transportation facilities, trails, or the West Elk IRA. Altern alive B Existing level of use related to West Elk Mine operations on highway 133 would be extended by approximately 3 years. Cracks may occur in roads and trails, but would not affect overall quality or usability. Some repairs may be necessary. Approximately 4.4 miles of temporary roads may be needed for post-lease development, potentially some in the West Elk IURA. Existing level of use related to West Elk Mune operations on Highway 133 would be extended by approximately 2.5 years. Cracks may occur in roads and trails, but would not affect overall quality or usability. Some repairs may be necessary. Approximately 3.6 miles of temporary roads may be needed for post-lease development a simall portion of which could be in the West Elk IRA. Heritage Resources Alternative A There would be no effects on cultural or historic sites due to no activity. Alternative B There would be no effects on cultural or historic sites. Stipulations to survey for these sites and requirements of Federal law and policy would protect such sites. Altternatide C There would be no effects on cultural or historic sites. Stipulations to survey for these sites and requirements of Federal law and policy would protect such sites. Visual. Qlaalaq Altern-d"i'V A There would be no effects on visual quality. f? tWe radri,e Most people would not notice impacts from subsidence. Post-lease development would be visible, but would be consistent with Forest Plan standards for visual quality. 1/lost people would not notice impacts from subsidence. Post-lease development would be Dry Fork Luse-By-Application FEIS S-9
