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.
The former Kingdome site in downtown Seattle carries contamination that Ecology attributes to historical industrial use of the area — elevated polycyclic aromatic hydrocarbons (PAHs), metals including lead, and petroleum hydrocarbons detected in soil and groundwater. Remediation under the Voluntary Cleanup Program included general soil remediation across multiple areas, the probable removal of underground storage tank UST-6, and inferred groundwater treatment, with work documented in reports spanning November 1997 through June 2002. Ecology issued a No Further Action determination following the completion of those remedial activities. 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 lead detected in soil and groundwater here is a marker of leaded-gasoline-era contamination — a release profile tied to industrial operators active in downtown Seattle well before leaded fuel was phased out in the mid-1980s. Those operators held occurrence-based CGL policies during the years their activities generated the PAH, metal, and petroleum contamination now documented at this site. The multi-year remediation expenditures from 1997 to 2002 — soil treatment, tank removal, groundwater work — represent costs incurred to address releases that fall squarely within those earlier policy periods.
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.
