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.
This property at 5314 15th Ave NW in Seattle formerly hosted a fueling station on its western portion, with underground storage tanks present and no documentation of their removal on record. The property, now operated as Chinook Development, has been designated Awaiting Cleanup under Washington State Ecology's Standard Cleanup program; no active remediation work has commenced. Contamination at the site is largely attributed to upgradient historical sources in addition to the on-site fueling infrastructure. 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 fueling station that operated on the western portion of this property was active before 1986, the year occurrence-based CGL policies began routinely including effective pollution exclusions. Underground storage tanks installed during those pre-1986 years remain in the ground with no documented removal, representing an unremediated legacy from the coverage period those historical policies were written to address. As investigation and remediation planning proceed, carriers who issued CGL policies to the fueling station operator during its operational window may hold obligations toward the cleanup costs now accruing at this site.
