This property has a documented history as a industrial and manufacturing facility going back to 1930. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property on Airport Way South in Seattle hosted a succession of industrial operations from the 1930s through the 1970s — among them a copper coil manufacturing and pattern shop, Cascade Pacific Equipment, Puget Sound Tractor Parts, and Seaboard Motors — alongside an adjacent gasoline station that operated from the 1920s through the 1960s. Cleanup under the Voluntary Cleanup Program included excavation and offsite disposal of 134 cubic yards of contaminated soil hot spots, backfill, and asphalt cap replacement; large-scale full excavation was evaluated as an alternative at estimated costs up to $3.45 million but was not selected as the preferred remedy. The site now operates under an Environmental Covenant restricting soil disturbance and groundwater use, with the existing impervious cap maintained over remaining contaminated soil and an ongoing groundwater monitoring program in place. The site has reached No Further Action status. 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 hydrocarbons, metals, and carcinogenic PAHs documented at this property originated from industrial and fueling operations spanning from the 1920s through the 1970s — entirely within the era when occurrence-based CGL policies carried no effective pollution exclusion. The succession of named operators across four decades means that multiple policy years and potentially multiple historical carriers may have been on the risk during the period when contamination accumulated. Documented remediation costs — soil excavation, cap maintenance, institutional controls, and continuing groundwater monitoring, with full-excavation alternatives evaluated into the millions — represent expenditures that those historical carriers may be obligated to recover.
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.
