This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property operated as the SeaTac Distribution Center, an air freight trucking facility that maintained an underground storage tank and fuel dispenser for diesel distribution to its vehicle fleet. A diesel release was identified in December 1989, and cleanup under the Voluntary Cleanup Program included excavation and off-site thermal desorption of 175 cubic yards of petroleum-contaminated soil, backfilling with 133 tons of rock, and removal and decommissioning of the underground storage tank and fuel dispenser. Ongoing stormwater catch basin cleaning and oil/water separator maintenance supported the remediation, which totaled $38,700 in documented costs and concluded with a No Further Action determination from Ecology. 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 diesel contamination at this site originated from an underground storage tank that was installed and operational years before the December 1989 release was identified — infrastructure consistent with pre-1986 operations when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The documented remediation expenditures — soil excavation, thermal treatment, tank removal, and long-term stormwater management — represent costs that historical carriers who issued CGL policies during the facility's early operational years may still be obligated to cover.
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.
