Revised Mine Document Nearly Ready

Two years after release of the original environmental impact statement on Asarco’s proposed Rock Creek Mine, a revised statement is due to be released soon.

The Montana Department of Environmental Quality and Kootenai National Forest are preparing to release the supplemental environmental impact statement on Dec. 22.

The proposed Rock Creek project would be a large underground copper and silver mine up the Rock Creek drainage in the Cabinet Mountains. The mine would extend underground beneath the Cabinet Mountains Wilderness Area. Asarco Inc. expects the mine to have a 30-year life span.

The supplemental environmental impact statement addresses alternatives in response to comments on the original statement. Among the changes are a different water treatment system, an enclosed railroad load-out facility and a new method for disposing of mine tailings.

A copy of the supplemental environmental impact statement will be available for viewing at the East Bonner County Library in Sandpoint; the Kootenai National Forest supervisor’s office in Libby, Mont.; the Lincoln County Library in Libby; the Cabinet District ranger station in Trout Creek, Mont.; and the Thompson Falls Library in Thompson Falls, Mont.

The document also will be posted on the Internet at
