This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property served as the City of Ellensburg's municipal maintenance shop, with underground storage tanks for waste oil, diesel, and gasoline supporting city operations. A leaking UST was excavated in 1991 along with approximately 3,100 cubic yards of petroleum-contaminated soil; an adjacent diesel tank had already been removed as early as 1971, and other USTs were removed prior to 1991 as well. Subsequent cleanup work has included extensive site assessments, installation of groundwater monitoring wells in 1999 and 2016, ongoing groundwater monitoring through at least 2017, and proposed in-situ bioremediation for residual soil and groundwater contamination. Cleanup is 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.
Petroleum contamination at this site originated from underground storage tanks that were installed and operated well before 1986 — a diesel tank alone was removed as far back as 1971, confirming decades of pre-1986 municipal fueling operations. Occurrence-based CGL policies in effect during that era carried no effective pollution exclusion under Washington law and remain enforceable today. The documented remediation expenditures here — large-scale soil excavation, UST removals, monitoring-well installation, years of groundwater sampling, and planned bioremediation — represent costs that historical carriers may be obligated both to reimburse and to fund through completion.
