Summary Information
(last updated on: 1/9/2012 10:08:43 AM)
[June 2011] In a 1996 Preliminary Assessment, DEQ identified potential public health and environmental threats related to contamination from this mine. Mercury contamination in nearby streams and in Cottage Grove Reservoir was linked to the Black Butte Mine area, including surface water runoff of contaminated soil from an estimated 300,000 cubic yards of mine tailings. In U.S. EPA's 1999 Site Investigation, unsafe levels of arsenic and mercury in mine tailings and soil at the mine were documented, confirming that the Black Butte Mine posed a serious threat to public and environmental health.
In 2002, DEQ designated Black Butte Mine as an Orphan site, to expedite investigation and cleanup. Partly because of DEQ's inadequate Orphan funding availability, EPA added the site to the NPL (federal Superfund list) in March 2010.
