This property has a documented history as a gasoline service station going back to 1928. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property has served as a gasoline service station since at least 1928, with Unocal demolishing the former McKales station and constructing a new facility on the site in 1968. Underground storage tanks on the property included two 10,000-gallon gasoline tanks, a 550-gallon waste oil tank, and a 550-gallon heating oil tank installed in 1968, plus a 10,000-gallon diesel tank added in 1977. The station operated until its demolition in 1992, and cleanup activities under the Voluntary Cleanup Program have been ongoing since at least 1990 — encompassing UST removal, contaminated soil excavation, free product recovery from groundwater, a soil vapor extraction pilot test, and quarterly groundwater monitoring. 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 property traces to underground storage tanks installed and operated across decades of service station use beginning well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — tank removals, soil excavation, free product recovery, vapor extraction, and years of ongoing groundwater monitoring — represent costs tied directly to releases from those pre-1986 operations. Historical carriers who issued CGL policies to the operators during that window may be obligated both to recover past cleanup costs and to fund the remediation work that continues at this site.
