This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
During a Washington State Department of Transportation road expansion project along SR 202, a contractor discovered a 660-gallon gasoline underground storage tank on WSDOT property and pulled it in August 2021; the tank was found to have a hole in the bottom. Petroleum-impacted soil was excavated at the time of tank removal, with the initial release report having been filed in January 2021. Further site characterization and cleanup remain necessary before the site can reach closure. 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 tank's unregulated status — meaning it was never registered under the federal Underground Storage Tank rules that took effect in 1988 — strongly implies installation and active use well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. A hole in the tank bottom is consistent with long-term degradation from historical gasoline storage, pointing to a release that likely began during the pre-1986 coverage window. The characterization and remediation costs still ahead for this site could plausibly be funded through historical CGL policies tied to the era when the tank was actively in service.
