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 residential property in Ridgefield harbored a former gasoline underground storage tank that was decommissioned after a suspected gasoline release was discovered during its removal. Remediation under the Standard Cleanup program included excavation of petroleum-impacted soil to a depth of 20 feet; the less than 100 cubic yards of excavated material was chemically and mechanically treated on-site by the property owner, with the intent to use it as backfill. Cleanup work at the site 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 presence of lead in the soil samples tied to this UST is a strong indicator that the tank held leaded gasoline, which was phased out of commercial use by 1986 — placing the contamination-generating operations squarely within the era of occurrence-based CGL policies that carried no effective pollution exclusion. Those historical policies may be obligated both to recover the documented remediation expenditures already incurred — tank removal, excavation, and on-site soil treatment — and to fund whatever additional investigation and cleanup the Standard Cleanup program ultimately requires to close this site.
