This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The former ASARCO Tacoma Copper Smelter operated for more than 90 years at Ruston before smelting ceased in 1985 and the facility closed in 1986, making it one of the longest-running heavy industrial operations in Pierce County. Airborne deposition of arsenic, lead, and cadmium from the smelter contaminated soils across a wide downwind area, including Vashon and Maury Islands, which have since been designated as the Tacoma Smelter Plume Site under MTCA. Multi-year Superfund and MTCA response actions are underway, including public education, investigation, and planned soil excavation. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
Why Historical Insurance Policies May Be Accessible
Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.
ASARCO's smelting operations at Ruston spanned more than nine decades, meaning commercial general liability policies were issued and renewed to the company — and its predecessors — across generation after generation of coverage periods. The arsenic, lead, and cadmium contamination now driving Superfund and MTCA cleanup costs accumulated continuously throughout those decades of smelting activity, each year of operation representing another policy period that may carry occurrence-based coverage obligations. Carriers who wrote CGL policies for ASARCO during that long operational window face potential liability for remediation costs tied directly to the contamination the smelter produced over those years.
