This property has a documented history as a gasoline service station predating 1986. 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 fuel dispensing site with at least one 1,000-gallon underground storage tank, which was decommissioned by removal on July 9, 1989; at the time of removal the tank was found to be compromised, with an estimated 5,200 gallons of gasoline released to the subsurface. Remediation included excavation of approximately 50 cubic yards of petroleum-contaminated soil and annual groundwater monitoring to assess natural attenuation. Several monitoring wells were decommissioned in 1997 after natural attenuation was determined to be successful, and the site currently carries a Construction Complete-Performance Monitoring designation. 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 underground storage tank and fuel dispensing operations at this site predate 1986 — lead detected in soil samples reflects use of leaded gasoline, which was phased out of commercial sale before that year, and the tank was already in place when it was removed in 1989. Occurrence-based CGL policies issued during that pre-1986 window had no effective pollution exclusion and may still be obligated to respond to contamination originating from those operations. The documented remediation expenditures — tank removal, soil excavation, and years of groundwater monitoring — represent costs that historical carriers may be obligated to recover, and the ongoing performance-monitoring phase represents present and future expenses those same policies could help fund.
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.
