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 site is the location of a former gasoline station that was removed during the construction of Interstate 5, with petroleum contamination — gasoline-range hydrocarbons (TPH-G), benzene, and naphthalenes — linked to that historical operation and potentially to underground storage tanks associated with it. Cleanup has commenced as an Independent Action integrated into the multi-year I-5/SR 539 Baker Creek and Spring Creek Fish Passage Project, which includes planned excavations for culvert replacement and stream grading. Investigation-derived waste generated during site sampling has been collected and managed for disposal. 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 here traces to a retail gasoline station that was operating before Interstate 5 was constructed through this corridor — meaning the source operation, and its associated CGL coverage, predates 1986. Costs already expended at this site — investigation, sampling, and investigation-derived waste disposal — represent documented remediation expenditures that historical carriers who issued CGL policies to the gasoline operator during that window may be obligated to recover. As excavation and stream-grading work continue under the fish passage project, those same pre-1986 policies may also fund the remediation still ahead.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
