The purpose of the Holden Mine Project is to rehabilitate the mine tailings and piles associated with activities at the Holden Mine from 1938 until its closure in 1957. Rehabilitation is necessary to reduce existing and potentially adverse environmental effects. The Holden Mine tailings piles have been designated a moderately hazardous site by the Washington State Department of Ecology because of their potential for leaching into nearby Railroad and Copper creeks and the low pH of the water emerging from the mine entrance. The site is listed as a Category C1 Site, indicating the presence of hazardous substances confirmed by laboratory or field tests. 7 figs.
