This property has a documented history as a industrial and manufacturing facility going back to 1947. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property has served as the central telephone operations center for US WEST Communications since at least the late 1940s, when its three-story, basemented building was originally constructed, with an addition completed in 1955. Multiple underground storage tanks holding diesel fuel, bunker C oil, and kerosene — installed beginning in the mid-1950s to fuel emergency generators — were taken out of service or removed in the late 1960s through 1974, with contamination attributed to historical overfills and leaking fittings from those tanks. Cleanup work has included UST removals, excavation of approximately 15 cubic yards of contaminated soil, closure of additional tanks in-place by grouting, and continuous groundwater pumping through an oil-water separator, with quarterly groundwater monitoring ongoing since 1992. 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 heavy petroleum contamination at this site — diesel, bunker C oil, and kerosene — originated from tank installations and operations that predated 1986 by decades, squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The contamination is not tied to a single accident but to long-running overfills and leaking fittings from USTs active from the mid-1950s onward, creating the kind of gradual, multi-year release those pre-1986 policies were written to cover. The documented remediation costs — tank removals, soil excavation, groundwater treatment, and over thirty years of quarterly monitoring — represent expenditures the historical carriers may be obligated both to recover and to fund going forward.
