Environmental Impact Statement
Thompson Creek Mine Expansion and Land Exchange
The BLM, the U.S. Forest Service, the U.S. Army Corps of Engineers, the U.S. Environmental Protection Agency, the Idaho Department of Environmental Quality, and Idaho Department of Lands have prepared an environmental impact statement (EIS) to analyze the potential environmental effects of authorizing a modified mining plan of operations and issuing a Section 404 Clean Water Act permit for the Thompson Creek mine, and authorizing a related proposal to exchange lands in Custer and Bannock Counties.
On March 27, 2015 the agencies released the final EIS with a 30-day availability period. The decisions for the mine plan, 404 permit, land use plan amendment, and land exchange will not be issued until after the availability period and the agencies have had time to fully consider all public comments received during the availability period.

TCMC submitted a modified mining plan of operations (MMPO) to the BLM, U.S. Forest Service, and Idaho Department of Lands in December 2008 that would allow the mine to continue to produce molybdenum until approximately 2025. Under both the current mining plan of operations and the MMPO, the mine would continue to process the same amount of ore each day – approximately 30,000 tons from the bottom of the open pit. However, the mine would require additional area for waste rock and tailings storage. TCMC also began discussing a related land exchange with the BLM in May 2006 and proposed the land exchange in February 2009.
