This Final Environmental Impact Statement (EIS) assesses the environmental consequences of a federal decision to offer a federal coal tract located in southeastern Campbell County and northeastern Converse County, Wyoming for lease at a competitive, sealed bid sale, subject to standard and special lease stipulations. The Horse Creek Lease By Application (LBA) Tract as applied for by Antelope Coal Company includes approximately 2,840 acres containing approximately 356.5 million tons of federal coal. Antelope Coal Company operates the adjacent Antelope Mine and proposes to mine the Horse Creek LBA Tract as a maintenance tract for the existing mine, if a lease sale is held and they acquire the lease. This Final EIS describes the physical, biological, cultural, historic, and socioeconomic resources in and surrounding the project area. The focus for impact analysis was based upon resource issues and concerns identified during previous coal leasing analyses and public scoping conducted for this lease application. Potential concerns related to development include impacts to groundwater, air quality, and wildlife and cumulative impacts related to ongoing surface coal mining and other proposed development in the Powder River Basin of Wyoming.
