This property has a documented history as a gasoline service station going back to 1978. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property in Keyport operated as a gasoline service station for approximately 25 years, with four single-layer steel underground storage tanks and a pump island on the east side of the property. Cleanup activities from 2003 through at least 2007 included removal of all four USTs and associated piping in 2003, excavation and off-site disposal of approximately 595 cubic yards of contaminated soil in 2004, and backfilling with clean cover material. The site entered the Voluntary Cleanup Program in 2004, which was rescinded in 2006, followed by a site hazard assessment in 2007; cleanup work remains ongoing.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 at this property originated from single-layer steel underground storage tanks installed no later than the late 1970s — well before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. The documented remediation expenditures — tank and piping removal, nearly 600 cubic yards of soil excavation and disposal, site restoration, and regulatory oversight spanning multiple years — are costs tied directly to releases from those pre-1986 operations. Historical carriers who issued CGL policies during the station's operating window may be obligated both to recover past cleanup costs and to fund the remediation still ahead.
