This property has a documented history as a gasoline service station going back to 1974. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property was formerly operated as a gasoline service station, with three underground storage tanks that had been abandoned and left in place prior to pre-purchase due diligence conducted in 1996–1997. The tanks — single-walled steel, heavily corroded with numerous holes — were removed in 1999, along with 1,158.22 tons of petroleum-contaminated soil transported off-site for thermal desorption. Groundwater contamination from the historical operations was detected as early as 1996, and multi-year monitoring including well installation and purge sampling remains 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.
The contamination at this site traces to tank operations that predate 1986 on multiple independent indicators: single-walled steel tanks consistent with a mid-1970s installation, and soil samples from the 1999 excavation showing total lead concentrations of 57 mg/kg — a signature of leaded gasoline, which was phased out before 1986. Occurrence-based CGL policies issued to the service station operators during that pre-1986 window carried no effective pollution exclusion and remain potentially enforceable today. The documented remediation expenditures — three UST removals, excavation and thermal desorption of over 1,150 tons of contaminated soil, and continuing groundwater monitoring — represent costs those historical carriers may be obligated both to recover and to fund going forward.
