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.
A gasoline service station historically operated on the south portion of this property, comprising an auto repair building, a pump island, and three underground storage tanks dispensing gasoline, waste oil, and fuel oil. Under the Voluntary Cleanup Program, all three USTs were removed in 2021 and approximately 2,000 tons of petroleum-contaminated soil were excavated. Site investigation and characterization — including installation of six groundwater monitoring wells and drilling of multiple borings — was conducted between 2021 and 2022, and cleanup work is 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 petroleum contamination at this property originated from underground storage tank operations that predate 1986, the period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Two of the three USTs were removed at dates unknown prior to November 2021 — a records gap characteristic of pre-regulatory-era installations. The documented remediation costs incurred here — UST removals, excavation of 2,000 tons of impacted soil, and multi-well groundwater monitoring — are directly traceable to those historical operations, and historical carriers who issued CGL policies during that operational window may be obligated both to recover past expenditures and to fund the cleanup work still underway.
