EPA Releases Proposed Plan for Site Wide Repository at the Bonita Peak Mining District Superfund Site in San Juan County, Colorado

July 29, 2020 (San Juan County, Colo.)   – Today the U.S. Environmental Protection Agency (EPA) released a Proposed Plan for a site wide repository to centrally manage mine waste at the Bonita Peak Mining District (BPMD). The site consists of historic and ongoing releases from mining operations in three drainages—Mineral Creek, Cement Creek, and Upper Animas—which converge into the Animas River near Silverton, Colorado. A sitewide repository is needed for the proper long-term disposal of mine wastes at the BPMD site. Additionally, a sitewide repository is needed for permanent disposal of the sludge at the Interim Water Treatment Plant to allow for continued operation of the plant.
