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.
The Super Stop Store at 245 Lakeshore Dr in Pateros operated as a retail fuel station, with a confirmed petroleum tank system (UST ID# 6648) identified as the source of gasoline contamination in both soil and groundwater beneath the property. Washington's Department of Ecology has recommended remedial action to address the release, and the site is enrolled in the Standard Cleanup program with cleanup work 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.
UST #6648 at this property is the type of single-wall steel tank system routinely installed at retail fuel stations before federal underground storage tank regulations took effect in the late 1980s, making it a likely candidate for a pre-1986 operational history. Ecology's formal placement of this site in the Standard Cleanup program establishes a documented remediation obligation — the kind of confirmed environmental liability that occurrence-based CGL policies issued during the tank's operational years were designed to cover. Property owners facing the remedial costs that Ecology has now required may have recourse against carriers whose policies were in force when gasoline first began migrating into the soil and groundwater at this location.
