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.

Public Comments Due Sept. 26

Your comments are invited on a proposed cleanup action to clean up a small area at the Black Butte Mine Superfund Site that is the biggest ongoing source of mercury entering the Cottage Grove Reservoir watershed.

The proposed cleanup action will remove and stabilize mercury contaminated mine tailings, soil along the bank and sediment in and around Furnace Creek. These actions will reduce the amount of mercury being carried downstream and into the reservoir.

A full description of the proposed cleanup action and other alternatives considered is available in the Engineering Evaluation and Cost Analysis:
