This property has a documented history as a gasoline service station going back to 1963. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property housed a gasoline station dating to approximately 1963 or earlier, with underground storage tanks and fuel piping that remained on site long after fueling operations ceased. Cleanup under the Standard Cleanup program has included excavation and off-site disposal of an estimated 1,500 to 2,500 used oil containers and old UST piping, overdrilling and grouting of a compromised monitoring well to prevent cross-contamination, and quarterly and semi-annual groundwater monitoring ongoing since May 1998. Gasoline-range petroleum hydrocarbons, BTEX compounds, and lead have been detected in groundwater, consistent with releases from the former fueling infrastructure. 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 presence of leaded gasoline contamination at this site is a direct indicator that the underground storage tanks were in service well before 1986, when occurrence-based Commercial General Liability policies were still standard and carried no effective pollution exclusion in Washington. The remediation expenditures documented here — container and piping removal, well decommissioning, and years of groundwater monitoring — trace to releases from those pre-1986 fueling operations. Historical carriers who provided CGL coverage during the gasoline station's operating years may be obligated both to recover costs already incurred and to fund the monitoring that continues.
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.
