This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The Westbridge Building property operated as a warehouse and office facility with on-site gasoline and heating oil underground storage tanks. Remediation under the Voluntary Cleanup Program has spanned more than two decades, beginning with gasoline UST removal and soil excavation of 160 cubic yards in 1991, followed by additional excavations of 75 cubic yards in 1993 and 1,350 tons in 2001, along with recovery of 7,600 gallons of petroleum-affected groundwater and in-place closure of a heating oil UST. The facility remains in active commercial use as a warehouse and office, with ongoing assessment and cleanup needs identified through at least 2013. 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 that were in service well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. More than two decades of documented remediation expenditures — UST removals, thousands of tons of soil excavation, groundwater recovery, and continuing site assessment — represent costs that historical carriers who issued CGL policies during the pre-1986 operational window may be obligated both to reimburse and to fund as cleanup work continues.
