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.
Seven orphan underground storage tanks — unregulated by Ecology and buried beneath an asphalt surface, with fill ports concealed under a six-inch concrete pad — were discovered at this Chehalis property. All seven tanks were excavated and removed across three phases in May 2022, November 2022, and October 2023, along with associated petroleum-contaminated soil. Soil sampling has confirmed contamination with gasoline range organics and oil range organics exceeding Method A cleanup levels, and further remediation of remaining impacted soil is planned, making this an ongoing multi-year project. 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 seven tanks here were unregulated under federal UST rules, which were not established until 1986 — placing their installation and operation squarely in the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The petroleum contamination now requiring multi-phase soil excavation and continued remediation traces directly to those pre-regulation operations. Historical carriers whose CGL policies covered this facility during that window may bear both the obligation to recover documented remediation expenditures already incurred and to fund the cleanup work that remains ahead.
