| Abstract | The 2,700-acre Torch Lake site is a copper milling and smelting facility in Houghton County, Michigan. The lake, a repository of milling wastes, served as the waterway for transportation to support the mining industry. In the late 1960's, copper milling ceased. In 1972, a discharge of 27,000 gallons of cupric ammonium carbonate leaching liquor occurred into the north end of Torch Lake from the storage vats at the Lake Linden Leaching Plant. The state investigated the spill and found no harmful effects associated with the spill; however, discoloration of several acres of lake bottom was noted. The ROD addresses removal of debris, surface tailings, and slag pile/beach, and disposal of drums on the western shore of the site, as OU1, and remediation of slag pile locations through the mid-Keweenaw Peninsula, as OU3. The primary contaminants of concern affecting the soil, debris, and slag pile/beach are organics, including PAHs; and metals, including arsenic, chromium, lead, and copper. The selected remedial action for the site are included. |
