This property has a documented history as a gasoline service station going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property was the former location of two historic service stations, with underground storage tank systems dating to the 1950s. Between November 1997 and February 1998, cleanup under the Voluntary Cleanup Program removed 23 underground storage tanks, dry wells, an automotive hoist, grease pits, and contaminated soils from the site. Groundwater was pumped and retained in a 20,000-gallon baker tank for disposal, and institutional controls were put in place for residual contamination in the right of way. Primary cleanup was completed by 2000, and the site received a No Further Action determination with ongoing periodic reviews. 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 property originated from underground storage tanks installed as early as the 1950s — more than three decades before occurrence-based CGL policies gave way to claims-made forms with pollution exclusions. The documented remediation costs here — removal of 23 tanks, excavation and off-site disposal of impacted soil, groundwater recovery, and long-term institutional controls — were incurred to address releases tied directly to those pre-1986 service station operations. Historical carriers who wrote CGL policies covering this site during that operational window may still be obligated to reimburse those cleanup expenditures.
Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.
Recovering Costs from an Older Cleanup
If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.
