This property has a documented history as a gasoline service station going back to 1964. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property has operated as a Chevron-branded retail gasoline service station in Centralia, with underground storage tanks dating to at least the mid-1960s based on the steel USTs removed in 1989. Cleanup under the Voluntary Cleanup Program has included the removal of multiple USTs in 1989 and 1994, excavation of over 920 cubic yards of contaminated soil, operation of a Soil Vapor Extraction system from 1990 to 1995 that recovered 586.3 pounds of hydrocarbons, and ongoing groundwater monitoring. Chemical oxidation treatment was proposed in 2004, and the site transferred to the Petroleum Technical Assistance Program in 2019 with remedial action 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.
Petroleum contamination at this station — including lead in groundwater, a signature of the leaded-gasoline era — traces to underground storage tank operations that were well underway before 1986. Occurrence-based CGL policies issued to the operators during that pre-1986 window carried no effective pollution exclusion under Washington law and remain enforceable today. More than three decades of documented remediation expenditures — tank removals, large-scale soil excavation, vapor extraction, groundwater monitoring, and proposed chemical oxidation — represent costs that historical carriers may be obligated both to reimburse and to fund as cleanup continues.
