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 the U-Save service station, dispensing gasoline and diesel through underground storage tanks and fuel dispensers at 20717 Bothell Everett Highway. Groundwater monitoring records for the site date to March 1998, with investigations confirming TPH-G and BTEX contamination consistent with long-standing UST releases. Remediation under the Voluntary Cleanup Program has included a Soil Vapor Extraction system that removed 2,076 pounds of hydrocarbons, an Air Sparge system, aqueous sulfate injection, and carbon-based in-situ injections using PlumeStop® and ORC Advanced®, with multi-year quarterly groundwater monitoring continuing. 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 hydrocarbon contamination at this former service station — TPH-G and BTEX from underground gasoline and diesel storage — originated from operations that predated 1986, when occurrence-based CGL policies were standard and carried no effective pollution exclusion in Washington. The documented remediation record here — vapor extraction, air sparging, chemical injection, and sustained groundwater monitoring — represents a substantial cost trail tied directly to those pre-1986 UST releases. Historical carriers who issued CGL coverage to U-Save Oil Company during that operational window may be obligated to recover those past expenditures and to fund cleanup work that remains ongoing.
