This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
This property was occupied by United Builders, a wholesale and retail material supply company that installed and operated gasoline underground storage tanks on the northeast portion of the site. Cleanup under the Voluntary Cleanup Program included excavation of approximately 630 cubic yards of petroleum-contaminated soil, free product recovery, soil bio-treatment through land farming, groundwater treatment, and extensive groundwater monitoring from 2004 through 2015. Additional remedial work encompassed well abandonment, environmental covenants, and periodic reviews before the site achieved 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.
Petroleum contamination at this property originated from underground storage tanks operated by United Builders prior to 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — soil excavation, free product recovery, bio-treatment, groundwater treatment and over a decade of monitoring — represent costs incurred to address releases tied directly to those pre-1986 operations. Historical carriers who issued CGL policies during that operational window may still be obligated to cover the cleanup costs already spent to bring this site to closure.
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.
