This property has a documented history as a industrial and manufacturing facility going back to 1942. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The Kaiser Mead facility has operated as a primary aluminum reduction smelter since 1942, with Kaiser Aluminum & Chemical Corporation conducting aluminum smelting at its Mead Works plant near Spokane. Open storage of spent potlining material — a byproduct of the smelting process — released cyanide and fluoride into soil and groundwater over decades of operation. Cleanup work has included consolidation and capping of approximately 94,000 cubic yards of spent potliner and rubble piles, installation and operation of a pump-and-treat groundwater system with multiple treatment technologies, stormwater management improvements, and institutional controls established through an environmental covenant. Remediation is ongoing, with multi-year monitoring, operation, and maintenance continuing under the cleanup program. 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.
The cyanide and fluoride contamination at this site originated from disposal practices tied to smelting operations that began in 1942 — more than four decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. The documented remediation scope here — capping 94,000 cubic yards of spent potliner, operating a long-running pump-and-treat system, managing stormwater, and maintaining ongoing institutional controls — reflects the scale of expenditures directly traceable to those pre-1986 operational decisions. Historical carriers whose CGL policies covered Kaiser's Mead Works operations during that era may remain obligated both to recover costs already incurred and to fund the remediation work still under way.
