This property has a documented history as a gasoline service station going back to 1940. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property operated as a gasoline service station from the 1940s through approximately 1962, with underground storage tanks installed prior to 1962 and left in place for more than four decades before their removal in 2007. Site remediation included the removal of four USTs and excavation of approximately 6.7 tons of contaminated soil, with residual contamination addressed through an impermeable cap and an active groundwater containment program. Engineered controls remain in place under a long-term management plan requiring bi-annual groundwater monitoring and annual inspections of those controls. The site has reached No Further Action status under Standard Cleanup. 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.
Gasoline storage and dispensing at this property began in the 1940s — more than four decades before occurrence-based Commercial General Liability policies were displaced by forms carrying effective pollution exclusions. The detection of lead-impacted soil is a direct marker of pre-1986 gasoline formulations and reinforces the pre-1986 origin of the contamination. Historical CGL carriers whose policies were in force during the site's operational years may remain obligated to recover the documented remediation expenditures — UST removal, soil excavation, cap installation, and the ongoing groundwater monitoring program.
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.
