This property has a documented history as a industrial and manufacturing facility going back to 1900. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property has been in industrial use since the early 1900s, with operations spanning wooden automobile body manufacturing, airplane parts production, chemical manufacturing by Monsanto, and decades of truck manufacturing by Kenworth — including fiberglass fabrication, machining, painting, and fueling. Cleanup activities have been underway since 1986 and include decommissioning of numerous underground storage tanks, excavation of over 3,600 tons and 320 cubic yards of contaminated soil on-site plus 5,000 cubic yards on an adjacent property, groundwater extraction, application of oxygen-releasing compounds, installation and ongoing operation of an air sparging and soil vapor extraction system, and comprehensive stormwater system repairs and upgrades. Cleanup work remains ongoing. 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.
Contamination at this property — petroleum hydrocarbons, chlorinated solvents including 1,1,1-trichloroethane, and other industrial chemicals — originated from manufacturing operations that began decades before 1986, with facility infrastructure dating to the 1920s. Occurrence-based CGL policies issued to the operators during that extended pre-1986 window carried no effective pollution exclusion under Washington law and remain enforceable today. Four decades of documented remediation expenditures — tank removals, large-scale soil excavation, groundwater extraction, vapor extraction, and ongoing system operation — represent costs the historical carriers may be obligated both to recover and to fund going forward.
