This property has a documented history as a gasoline service station going back to 1971. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property has operated as a fuel service station since at least 1971, when the original single-walled steel underground storage tanks are estimated to have been installed. Contamination — gasoline-range petroleum hydrocarbons and BTEX compounds — was encountered during decommissioning of those original USTs in December 1996, attributed to historical overfilling and decades of fuel dispensing. Cleanup under the Voluntary Cleanup Program has included UST and product-line excavation, soil removal, Dual-Phase Vacuum Extraction modified to a Soil Vapor Extraction system with proposed Air Sparging, and ongoing groundwater monitoring since 2005, with projected remaining costs exceeding $260,000. The property continues to operate as a Shell-branded fuel station and convenience store. 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 originated from underground storage tanks installed and operated roughly fifteen years before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion. The documented remediation expenditures — tank removal, soil excavation, vapor extraction, air sparging, and over two decades of groundwater monitoring — trace directly to releases from those pre-1986 operations. Historical carriers who issued CGL policies during that operational window may be obligated both to reimburse cleanup costs already incurred and to fund the substantial remediation work still ahead.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage.
