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 operated as a CHS retail gasoline station beginning in the late 1970s, with five underground storage tanks, associated piping, and fuel dispensers serving the public. A diesel fuel line leak was identified during routine leak detection testing, leading to cleanup activities under the Voluntary Cleanup Program that have been ongoing since at least 2006 — including removal of all five USTs, excavation and disposal of approximately 7,400 tons of contaminated soil, LNAPL recovery, building demolition, vapor barrier installation, and long-term groundwater monitoring. Institutional controls and environmental covenants are in place, with monitored natural attenuation under consideration. 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 and fuel dispensing infrastructure installed and operated throughout the late 1970s and early 1980s — squarely within the era when occurrence-based CGL policies carried no effective pollution exclusion in Washington. The scale of documented remediation — 7,400 tons of soil removal, LNAPL recovery, years of groundwater monitoring, vapor barriers, and ongoing institutional controls — represents substantial expenditures already incurred and future costs still accumulating. Historical carriers who provided coverage during those pre-1986 operational years may be obligated both to reimburse past cleanup costs and to fund the remaining remediation.
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. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
