Map of early, current and future Black Butte Mine clean-up activities.

Site Summary

The Black Butte Mine Superfund Site is located near Cottage Grove, Oregon in Lane County. Mercury and other contamination from tailing piles at the abandoned mine site affect creeks that flow into Cottage Grove Reservoir and the Coast Fork Willamette River. The Black Butte Mine operated between the 1890's and late 1960's and was one of the largest mercury mines in Oregon. The Black Butte Mine site was added to EPA's National Priorities List on March 4, 2010. The listing makes the site eligible to receive federal funds for long-term cleanup.

Community Involvement

The Community Involvement Plan outlines activities that EPA plans to ensure that the public remains informed about site activities throughout the cleanup process. We welcome your input and ideas for improving our community outreach at any time.

Site Progress

Project Updates will be periodically posted to help keep the community informed about site progress.
