| Abstract | The 10-12 square mile Commencement Bay-Nearshore/Tideflats site encompasses shallow water, shoreline, waterways, and adjacent land in Tacoma, Pierce County, Washington at the southern end of the main basin of Puget Sound. The site has been divided into eight different operable units (OUs). Part of the site is on the 67-acre Asarco Tacoma Smelter area, an inactive copper smelter facility adjacent to Puget Sound, which is the focus of the remedial action. A 1987 ROD addressed OU3-Tacoma Tarpits, a historical coal gasification site. A 1989 ROD addressed OU1-CB/NT sediments and OU5-CB/NT sources, both associated with marine sediments. The ROD provides an interim remedy for OU7, the Asarco Demolition, and addresses further clearing of the site to prevent the threat of an uncontrolled collapse of the stack and to minimize contaminant migration to offsite surface water. The primary contaminants of concern affecting the debris, sludge, and surface water are metals including arsenic, chromium, and lead; and other inorganics including asbestos. The selected interim remedial action for the site is included. |
