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 a former ARCO gasoline service station (Facility No. 4329) before the station was demolished. Contamination from petroleum products — including gasoline-range organics (GRO), diesel-range organics (DRO), BTEX compounds, MTBE, and lead — has been documented in groundwater at the site. Cleanup under the Voluntary Cleanup Program has involved multiple in-situ chemical injection events using magnesium sulfate and ammonium sulfate for anaerobic bio-oxidation, disposal of generated wastewater, and multi-year semi-annual and quarterly groundwater monitoring. Remediation work 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.
The presence of lead in groundwater at this site is a direct marker of leaded gasoline contamination, tying the source of the release to operations predating 1986 — the year leaded gasoline was phased out of commercial use. Occurrence-based Commercial General Liability policies issued to ARCO or its operators during that pre-1986 window carried no effective pollution exclusion in Washington and remain enforceable against documented cleanup costs. The remediation expenditures here — repeated chemical injection campaigns, wastewater disposal, and years of intensive monitoring — are the type of costs those historical carriers may be obligated both to recover and to fund going forward.
