of and Need for Action irregular-shaped pads and rapid reclamation will minimize visual disturbance. Livestock Management Conflicts with livestock managers may occur in the vicinity of the existing corrals from road use. Livestock AUMs may be temporarily reduced because of the reduction in forage due to construction activities and vegetation disturbance. Livestock may concentrate along new roads causing additional disturbance. Livestock may have reduced water availability due to subsidence of existing ponds. Livestock may attempt to drink from MDW reserve pits if not fenced. Wilderness character may be affected in the West Elk Wilderness due to activity in the adjacent roadless area. The area of the proposed action includes previously roaded areas of West Elk Inventoried Roadless Area. The West Elk Wildemess Area lies from one to three miles south and southeast of the project area. Therefore, there will be no effects on the West Elk Wildemess. Wilderness access may be curtailed by construction activities. Public access to the Wilderness does not exist in the project area as there are no System routes or trailheads present. Air Quality Fugitive dust emissions from construction activities and road use, and venting of hydrocarbon gasses and vehicle emissions may affect air quality of Class I airsheds. Methane emissions from wells would increase greenhouse gas emissions. Water Quality Construction and ground disturbing activities may cause a decline in water quality. Safety/Emergency Response Mining operations are dangerous to well-being of the workers and the public using the area. Cumulative Impacts Many surface disturbing activities have been conducted in the vicinity of the project area including previous MDW projects, livestock grazing and management, recreational activities, and irrigation projects which all contribute to issues such as erosion and sedimentation. Reasonably foreseeable actions may affect resources analyzed. Non-Significant Issues Non-significant issues and reasons regarding their categorization as non-significant include: Primary use of non-public project area access roads may reduce conflicts with recreational users. Most of the routes in the project area are user-created (illegal) or permitted resource extraction or management routes not open to the public. Global warming -methane is a greenhouse gas. The FEIS has added analysis of methane as a greenhouse gas to Air Quality analysis. Due to the immeasurable quantity of methane released on a global scale from this project, global warming or climate change are considered outside the scope of this document, and while the greenhouse gas component is addressed, global warming is anon-significant issue because no methodology or models exist to measure the effect of this project at a scale of that magnitude.
