This property has a documented history as a gasoline service station going back to 1988. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.
This property has operated as a gasoline fueling station since at least 1988, with underground storage tanks dispensing fuel for retail sale at 5940 E Marginal Way S in Seattle. Two first-generation 1,000-gallon USTs were removed in 1993, followed by a limited excavation of petroleum-contaminated soil in 2014. Annual groundwater monitoring ran from 2003 through at least 2025, with new monitoring wells installed in 2024, and the site has received a No Further Action determination under the Standard Cleanup program. 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 petroleum contamination here originated from first-generation underground storage tanks whose designation and 1993 removal date strongly suggest installation well before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. More than two decades of documented remediation expenditures — tank removals, soil excavation, and continuous groundwater monitoring — were incurred to address releases tied to those legacy tank systems. Historical carriers who issued CGL policies covering the station's operations during that pre-1986 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.
