Welcome to the Coeur d’Alene Basin Commission site

Our mission is to protect the people of Idaho

by coordinating the environmental cleanup

and restoration

of the Coeur d'Alene Basin.

The Bunker Hill Mining and Metallurgical Complex Superfund Site includes environmental cleanup and restoration work in areas contaminated by mining waste in the Coeur d’Alene River Watershed, Coeur d’Alene Lake, and the upper reaches of the Spokane River. The total length of the system is 166 river miles through northern Idaho and eastern Washington; and the boundary includes an area of about 1,500 square miles. It is one of the largest Superfund sites in the nation. The Basin Environmental Improvement Project Commission (BEIPC) was created to coordinate cleanup, environmental restoration and related measures in the Basin.
