SPOKANE — Federal environmental regulators began work this week to clean up asbestos and potential cancer-causing chemicals at the abandoned aluminum smelting site previously operated by Kaiser north of Spokane.
The work is expected to last the rest of 2020 and is necessary because people continue to enter the sprawling, 500-acre-plus compound north of Hawthorne Road, said Bill Dunbar, a public affairs specialist with the Environmental Protection Agency in Seattle.
“People who get on the site are exposed to pretty hazardous stuff,” Dunbar said.
That includes the previously popular insulation material asbestos, which has been linked to certain types of lung cancer. EPA regulators visited the site in May 2019 and discovered large quantities of the material in siding used in the buildings, which date to World War II. The smelter was originally constructed by the federal government in 1942 to supply metal for the war effort, and was purchased in 1946 by Kaiser Aluminum & Chemical Co., which operated the plant until 2000. In 2004, a St. Louis-based company bought the property and stripped the site of copper and other metals for sale on the scrap market.
The facility was later sold to a real estate investment firm interested in redeveloping the land, but the property was sold again to a Canada-based firm in 2014 for $1 million, according to property records. Kaiser still owns an undeveloped parcel to the north of the plant site, where two retention ponds are collecting runoff that is contaminated by asbestos and polychlorinated biphenyls, or PCBs, and leeching into nearby Deadman Creek, according to EPA analysis.
