This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The Gasamat Oil Corp property in Aberdeen is an active gas station on a 0.45-acre parcel, with four documented underground storage tanks that held both leaded and unleaded gasoline. Site investigations and monitoring have been underway since at least 1988, with groundwater monitoring continuing into 2024–2025; cleanup activities to date include excavation, decommissioning of a well, and installation of a compacted soil cover for containment. A Remedial Investigation and Feasibility Study is planned for 2025, and cleanup work remains 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 documented presence of leaded gasoline in the site's USTs establishes that fueling operations were active before 1986 — the period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Petroleum hydrocarbons and chlorinated solvents now detected at the property trace directly to those pre-1986 operations, not to any discrete recent event. With over three decades of documented investigation and containment expenditures on the books and a formal remedial investigation still forthcoming, historical carriers who issued CGL policies during the leaded-gasoline era may be obligated both to recover costs already incurred and to fund the cleanup work ahead.
