| Description | The Washington Department of Ecology (Ecology) invites you to comment on cleanup documents for the USG Interiors, LLC site in Puyallup. The site is located at 1005 River Road in Puyallup, Washington. Prior to 1971, the USG facility used slag from the former Tacoma Asarco copper smelter as a raw material to produce rock wool, a mineral fiber insulation. The manufacturing waste that consisted of “baghouse dust” and “shot”, was used as fill on the site to raise the grade. In the 1980s, USG learned that the slag and waste contained high concentrations of arsenic, and had contaminated soil, sediments in the Puyallup River, and groundwater. In 1984, USG entered into an Agreed Order to assess groundwater contamination on the site. Between 1984 and 1985, USG removed contaminated soil, however in 2006, they conducted a site assessment and found soil and ground water with arsenic concentrations above the state Model Toxics Control Act (MTCA) cleanup levels. In 2007, USG conducted a Remedial Investigation and Feasibility Study (RI/FS). Now, Ecology and USG are proposing to implement the Cleanup Action Plan (CAP) to address the remaining contamination. | ||||
