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 recover the cleanup costs already paid.
This property operated as a gasoline service station and auto repair facility, with three underground storage tanks storing gasoline and an additional 1,000-gallon waste oil UST. Cleanup under the Voluntary Cleanup Program included extensive soil excavation in 1998, removing over 3,100 tons of contaminated material for thermal treatment and landfill disposal at depths reaching 10 to 14 feet, followed by groundwater extraction and treatment pumped to the sanitary sewer from January through at least August 1999. A Restrictive Covenant was recorded in 2000 and corrected in 2010, with periodic reviews completed in 2010 and 2015; the site has 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.
Petroleum contamination at this property originated from underground storage tanks and fueling infrastructure that were installed and operated well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — large-scale soil excavation, thermal treatment of thousands of tons of impacted material, groundwater extraction, and years of institutional controls — represent substantial cleanup costs tied directly to those pre-1986 operations. Historical carriers who issued CGL policies during the period these tanks were in service may still be obligated to recover those costs.
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.
