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 at 8530 Evergreen Way in Everett operated as a Shell-branded gasoline service station, with underground storage tanks and fuel dispenser islands serving retail customers. Cleanup under the Voluntary Cleanup Program has included multi-year groundwater monitoring, decommissioning of monitoring wells, and preparation for remedial soil excavation. Groundwater sampling has identified gasoline-range petroleum hydrocarbons and lead at concentrations exceeding MTCA Method A cleanup levels. 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.
Lead detected in groundwater at this site — at levels up to 133 micrograms per liter, well above the 15 microgram cleanup standard — points to the use of leaded gasoline, a product largely phased out before 1986. That link ties the contamination to the facility's pre-1986 fuel-dispensing operations, the period when occurrence-based CGL policies would have been in effect for Shell and its station operators. With remedial soil excavation still ahead and groundwater monitoring ongoing, the cleanup costs this property faces are not yet fully incurred — historical carriers whose policies covered this station's pre-1986 operations may be obligated both to reimburse past investigation and monitoring expenses and to fund the remediation work still to come.
