This property has a documented history as a public works and maintenance facility going back to 1971. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property has operated as a Washington State Department of Transportation maintenance facility since at least 1971, with underground storage tanks used for dispensing gasoline and diesel fuel and collecting waste oil. In 1989, three USTs totaling 4,800 gallons of capacity were removed, and contaminated soil was over-excavated, stockpiled, and tested for potential reuse as fill material. Cleanup work at the site is ongoing. 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 petroleum contamination here — from gasoline, diesel, and waste oil storage tanks in active use well before 1986 — traces directly to the era when occurrence-based Commercial General Liability policies were still standard and carried no effective pollution exclusion. The documented remediation work, including UST removal and soil excavation, was incurred to address releases tied to those pre-1986 operations. Historical carriers who issued CGL policies to the facility or its operators during that window may remain obligated to recover those past cleanup costs and to fund continuing remediation.
