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 fund a cleanup — and recover costs already spent.
This private residential property was used by a former owner to store approximately 7,000 pounds of industrial chemicals — solvents, resins, VOCs, petroleum hydrocarbons, and metals — obtained through Boeing surplus sales and held across 34 containers on site. By the time Boeing was contacted in December 2003 to assist with disposal, several structures on the property, including a Quonset shed and a boathouse, had collapsed, indicating the storage practices had persisted for an extended period prior to discovery. Cleanup involved full removal of the stored chemicals and miscellaneous debris, excavation of 38 tons of contaminated soil including a resin layer, and post-cleanup compliance monitoring through soil and septic sampling. 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 chemicals stored here — Boeing-surplus solvents, VOCs, and petroleum hydrocarbons — are the same industrial compounds whose slow, ongoing release into soil and groundwater fell squarely within the coverage grant of pre-1986 CGL policies. The collapsed state of the Quonset shed and boathouse by 2003 places the active storage period well into the era before effective pollution exclusions were routinely added to CGL forms, meaning the carriers who issued policies during those years may still bear obligations. Excavation costs, chemical disposal, and compliance monitoring tied directly to that storage window are the kinds of remediation expenditures that historical insurers could be called on to fund.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
