This property has a documented history as a gasoline service station going back to 1955. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The Chevron 90709 property has operated as a fueling and service station since 1955, with underground storage tanks for used oil, fuel oil, and unleaded gasoline — including two 10,000-gallon gasoline USTs — present at the site. A release was reported in 1989, triggering a regulatory cleanup process that has included UST removal and replacement, soil excavation, on-site groundwater treatment using granular activated carbon filtration, a vapor extraction system pilot test in 1991, and multi-year groundwater monitoring from at least 1991 through 1998. The property continues to operate as a fueling and service station under the Tesoro brand. 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.
Fueling operations at this site began in 1955, more than three decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The petroleum contamination documented here traces directly to those decades of pre-1986 underground storage tank and dispensing operations. Documented remediation expenditures — UST removals, soil excavation, groundwater treatment, and years of monitoring — represent costs that historical carriers whose policies covered the site during its earliest operational decades may be obligated both to recover and to fund going forward.
