This property has a documented history as a bulk fuel distribution terminal going back to 1944. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property housed two 125,000-gallon underground storage tanks constructed in 1944, used to store Bunker C fuel oil and later diesel at Boeing's Renton facility. Petroleum contamination was discovered in 1985, and the tanks were partially demolished in 1988–1989 after years of disuse. Cleanup under the Standard Cleanup program involved excavation of more than 11,410 tons of soil and gravel across an area exceeding 18,000 square feet and 12 feet deep, removal of 2,100 tons of concrete and 80 cubic yards of wood debris, and the extraction, treatment, and discharge of 2.24 million gallons of petroleum-affected groundwater. 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.
The fuel oil releases at this property trace to underground storage tanks installed in 1944 and operated for decades — well within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The scale of documented remediation — massive soil excavation, millions of gallons of groundwater treated, infrastructure demolition and reconstruction — represents substantial expenditures tied directly to contamination that originated under those pre-1986 policies. Historical carriers who covered the facility's operations 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.
