This property has a documented history as a industrial and manufacturing facility going back to 1965. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property served as a Union Pacific Railroad section toolhouse, with a 500-gallon underground storage tank used to store gasoline for internal railroad operations. In 1990, the UST was excavated and removed, along with product recovery and off-site tank disposal; groundwater monitoring wells were installed and sampled as part of the initial response. A 2008 follow-up document confirmed that further remedial actions are still required at the site, including multi-year groundwater monitoring and a Site Hazard Assessment, underscoring the ongoing nature of the cleanup. 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 gasoline contamination at this property traces to a UST that was reported to the state in 1986 and likely installed decades earlier, placing its entire operational life squarely within the era of occurrence-based Commercial General Liability policies that carried no effective pollution exclusion. Remediation costs have already accrued — tank removal, product recovery, groundwater monitoring — and the 2008 determination that additional work including a Site Hazard Assessment is still required means further expenditures lie ahead. Historical carriers who insured the railroad's operations during that pre-1986 window may be obligated both to recover past cleanup costs and to fund the remediation that remains.
