USG Interiors, LLC Puyallup Fact Sheet

Site Description

The site is located at 1005 River Road East between River Road and the Puyallup River. It is 1.58 acres and consists of four USG-owned tax parcels that include portions of the Bonney Lake Used Cars property to the west, Market Place Auto property to the east, and Pierce County’s Inter-County River Improvement Right-of-Way along the Puyallup River to the north.  The Riverwalk Trail, a paved path at the top of the river bank, is used for biking and walking.  Currently, there are no plans for future land use at the site.

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 and disposed of it at a hazardous materials landfill.  Ecology required USG to monitor the groundwater after the cleanup.  In 2006, USG conducted a site assessment and found soil and groundwater with arsenic concentrations above the state Model Toxics Control Act (MTCA) cleanup levels.  In 2007, USG conducted a Remedial Investigation (RI) and Feasibility Study (FS). Now, Ecology and USG are proposing to implement the Cleanup Action Plan (CAP) to address the remaining contamination.



What is rock wool?
Rock wool is an insulating and fire-proofing material. It is made by heating rock until it is molten, and blowing or spinning it into fine fibers
