This property has a documented history as a gasoline service station going back to 1962. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.
This property operated as a Humble Oil / Exxon service station beginning in 1962, with six underground storage tanks totaling 22,850 gallons and two pump islands dispensing gasoline to the public. Fuel dispensing ceased in June 1992, and all six USTs were removed in April 1993. Cleanup under the Standard Cleanup program included extensive overexcavation and land-treatment of contaminated soils from November 1995 through September 1996, along with groundwater pumping, granular activated carbon filtration, and reinfiltration. The property is currently an operating auto repair establishment. 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 site resulted from decades of fuel storage and dispensing operations that began in 1962 — more than two decades before occurrence-based Commercial General Liability policies were replaced by claims-made forms with pollution exclusions. The documented remediation expenditures — tank removal, large-scale soil excavation and treatment, groundwater recovery and carbon filtration, and ongoing seep monitoring — are costs tied directly to releases from piping leaks and inadequate fill/spill containment during those pre-1986 operations. Historical carriers who issued CGL policies to the station's operators during that window may still be obligated to reimburse those cleanup 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.
