About the Project

The U.S. Department of the Interior (DOI), Office of Surface Mining Reclamation and Enforcement (OSMRE), Western Region Office, has prepared an environmental assessment (EA) for a Federal Mining Plan Modification for Dry Fork Mine Federal Coal Leases for Federal coal lease WYW-0311810 (the Project). OSMRE prepared the EA to evaluate the environmental impacts resulting from the proposed mining plan modification, pursuant to the requirements of the National Environmental Policy Act of 1969 (NEPA).

The Dry Fork Mine (DFM) is located approximately 4.5 miles north of Gillette, WY and is operated by Western Fuels Wyoming. The DFM uses a truck and loader mining method. The Project proposes to add approximately 656.4 acres and 58.1 Mt of federal coal to the approved federal mining plan. Using an estimated 6.0 million tons per year production rate, the Project would extend the life of the mine by approximately 9.7 years, to 2064.

OSMRE has prepared an environmental assessment (EA), to analyze environmental impacts of the proposed mining plan modification. As required by the National Environmental Policy Act of 1969, the EA discloses the potential for direct, indirect, and cumulative impacts. Resources analyzed in the EA include topography and geology, air quality and climate, social and economic resources, water resources, soils, biological resources, and land use and recreation.
