This property has a documented history as a gasoline service station going back to 1973. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The Gold Nugget Market operated as an active gas station in Buena, Yakima County, until its closure in 1998, when two underground storage tanks were removed from the property. Petroleum contamination was first discovered in 1993, and in 2000 approximately 400 tons of contaminated soil were excavated and removed from the site. Groundwater monitoring has been ongoing since 1998, and planned future work includes additional soil excavation, groundwater treatment, demolition of structures to access contaminated areas, and decommissioning of an artesian well. 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 petroleum releases at this site originated from underground storage tanks likely installed decades before 1986, during the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Contamination was already present by 1993, tying the releases squarely to that pre-1986 operational window. The remediation costs incurred to date — tank removals, large-scale soil excavation, years of groundwater monitoring — and the significant cleanup work still ahead represent expenditures that historical CGL carriers may be obligated both to reimburse and to fund going forward.
