This property has a documented history as a gasoline service station going back to 1964. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as a Chevron Service Station with two pump islands and five underground storage tanks installed in 1964, one of which stored leaded gasoline. The USTs were removed in 1984, and contamination was discovered during a 1991 excavation that removed 1,300 cubic yards of soil — 360 cubic yards of it contaminated — along with treatment and discharge of 120,000 gallons of petroleum-affected groundwater. Groundwater monitoring continued from 1992 through 2011, and a feasibility study for soil vapor extraction was conducted but never implemented; several proposed remedial action plans and Voluntary Cleanup Program applications were reviewed by Ecology without leading to further remediation. 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.
Petroleum contamination at this site traces directly to underground storage tanks installed in 1964 and operated for two decades before 1986, squarely within the era of occurrence-based Commercial General Liability policies that carried no effective pollution exclusion. The documented remediation expenditures — tank removal, large-scale soil excavation, on-site treatment, groundwater recovery, and nearly two decades of monitoring — represent costs tied to those pre-1986 operations. With cleanup still in progress and additional remediation potentially ahead, historical carriers who covered the Chevron station during its operational years may be obligated both to reimburse past expenditures and to fund the work that remains.
