This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as an ARCO retail gasoline service station until 1984, with an automotive repair shop also on site before 1985. Two leaking underground storage tanks were removed in 1984, revealing petroleum releases in soil and groundwater. Cleanup under the Voluntary Cleanup Program has spanned three decades, including removal of multiple USTs (gasoline, heating oil, and waste oil), excavation of over 6,500 tons of contaminated soil, pumping and off-site disposal of at least 162,300 gallons of affected groundwater, and ongoing quarterly groundwater monitoring. Remediation work remains active. 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 — including leaded gasoline constituents — originated from underground storage tanks operated during an era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Thirty years of documented remediation costs, from tank removals and massive soil excavations to groundwater treatment and long-term monitoring, trace directly to releases from those pre-1986 operations. Historical carriers who issued CGL policies covering this service station may still be obligated to reimburse past cleanup expenditures and to fund the remediation work that continues today.
