This property has a documented history as a industrial and manufacturing facility going back to 1967. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property operated for decades as the Willamette Industries Bellevue Corrugated Plant, an industrial manufacturing facility that maintained four underground storage tanks — installed in 1967, 1975, and 1980 — holding a combined 34,500 gallons of fuel for fleet vehicles and the plant boiler. In 1995, all four USTs were removed along with approximately 800 cubic yards of petroleum-contaminated soil; the excavated material was treated on-site through solid-phase remediation and landfarming before being used as backfill, and contaminated groundwater encountered during excavation was discharged to the sanitary sewer. Groundwater monitoring continued from 1995 through 2022, and Ecology issued a No Further Action determination in 2023. 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 releases at this site trace directly to underground storage tanks installed as early as 1967 — nearly two decades before the 1986 industry-wide shift away from occurrence-based Commercial General Liability policies with no effective pollution exclusion. One of the tanks stored leaded gasoline, which was phased out prior to 1986, placing the contamination origin squarely within the pre-1986 policy window. The documented remediation expenditures here — UST removal, soil excavation, on-site treatment, and nearly three decades of groundwater monitoring — represent costs that historical CGL carriers who issued policies to Willamette Industries during those operating years 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.
