This property has a documented history as a property with a heating oil tank going back to 1949. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property housed a warehouse with a 500-gallon underground storage tank used to store No. 2 fuel oil for the building's furnace from 1949 through 1986, when the tank was taken out of service after it was found to be leaking. The UST was permanently removed in 1989, accompanied by contaminated soil excavation, and multi-year LNAPL extraction followed in the early 1990s. Groundwater monitoring has been conducted at intervals since 1989, and the selected cleanup alternative — Institutional and Engineering Controls with a Restrictive Covenant and maintenance of impervious surfaces — carries a budget of $32,500. Cleanup work remains ongoing under the Voluntary Cleanup Program. 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 fuel oil release at this property originated from an underground storage tank that operated continuously from 1949 to 1986 — squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Decades of documented remediation expenditures, from tank removal and soil excavation through LNAPL recovery and long-term groundwater monitoring, trace directly to that pre-1986 operation. Historical carriers who covered the property during those 37 years of tank use may be obligated both to recover costs already incurred and to fund the ongoing institutional and engineering controls still required at the site.
