Centralia Mine, Environmental Assessment
About the Project
The U.S. Department of the Interior, Office of Surface Mining Reclamation and Enforcement (OSMRE), Western Region Office, is releasing the Environmental Assessment (EA) and unsigned Finding of No Significant Impact (FONSI) for the Centralia Mine Permit Number WA-0001E.
TransAlta Centralia Mining LLC (TCM) is the Permittee and Operator of the Centralia Mine, which is located at 1015 Big Hanaford Road in Centralia, Washington. TCM has filed a significant permit revision application with OSMRE. The permit revision application pertains to TCM’s coal mining operation under OSMRE Permit No. WA-0001E, issued on November 21, 1985, and under subsequent permit renewals, in accordance with regulations promulgated by the Surface Mining Control and Reclamation Act of 1977, at 30 Code of Federal Regulations (CFR) Section 773.4 and 30 CFR 774.15. TCM ceased active coal mining operations at Centralia Mine in 2006 and has since been conducting reclamation-only activities.
TCM is proposing the following significant revision of the existing surface coal mining permit and Permit Application Package (PAP): The proposed significant permit revision would change the land-use designation of approximately 130 acres from forestry to permanent impoundment (a lake). If no action is taken, TCM would continue to conduct reclamation activities per their current permit.
OSMRE has prepared an environmental assessment (EA), to analyze environmental impacts of approving the proposed significant permit revision for a land use change at the Centralia Mine Permit WA-0001E. 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, water resources, biological resources, land use, recreation, and public health and safety.
