This property has a documented history as a gasoline service station going back to 1977. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property at 801 SW 16th St in Renton was first developed in 1977, when the main building was constructed and two leaded gasoline underground storage tanks — a 6,000-gallon and a 250-gallon unit — were installed. The USTs operated until their removal in 1991, at which point approximately 10 cubic yards of petroleum-contaminated soil were excavated. Groundwater testing identified non-halogenated solvents, benzene, and petroleum-gasoline constituents at the site. The property entered the Voluntary Cleanup Program and has since received a No Further Action determination. 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 gasoline USTs at this property were installed in 1977 and operated for nine years within the pre-1986 occurrence-based Commercial General Liability policy era, when standard CGL policies carried no effective pollution exclusion. Petroleum releases from leaded gasoline storage during that 1977–1986 window are precisely the kind of gradual contamination those occurrence-based policies were written to cover. The documented remediation costs — tank removal, soil excavation, and groundwater investigation leading to the No Further Action opinion — represent expenditures that historical carriers who issued CGL policies during the facility's pre-1986 operations may still be obligated to reimburse.
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.
