This property has a documented history as a gasoline service station going back to 1950. 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 gasoline service station from 1950 through 1983, under successive operators including Shell Oil Co., Hal S Shell Service, and Circle K. The site was equipped with multiple underground storage tanks — a waste oil UST, two 2,950-gallon gasoline tanks, and one 2,000-gallon tank — along with fuel dispensers and service hoists. The property is now enrolled in Washington State's Standard Cleanup program, with active cleanup work underway. 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 at this property traces directly to underground storage tank operations that ran for more than three decades before 1986 — the last period in which occurrence-based Commercial General Liability policies were written without an effective pollution exclusion. Four USTs storing gasoline and waste oil, operating across multiple successive operators from the Korean War era through the early Reagan administration, represent a substantial and well-documented pre-1986 contamination source. Historical carriers who issued CGL policies to Shell Oil Co. or its successor operators during that window may be obligated to fund the ongoing Standard Cleanup costs now accruing at this site.
