This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property at 314 SW Main Street in Wilbur has operated as a gasoline station with underground storage tanks and pump dispensers, and currently functions as an operating convenience store with gasoline sales. Petroleum-impacted soil was first discovered in October 1998 during a general site upgrade, prompting excavation and off-site thermal treatment of 80 tons of contaminated soil. Subsequent work included a direct-push investigation in 2001, installation and development of groundwater monitoring wells in 2002, and ongoing groundwater monitoring with air-sparging treatment of purge water into 2003. A new Voluntary Cleanup Program project was initiated in 2017 to address additional contamination at the site. 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 tanks and former pump dispensers that predate 1986, the year occurrence-based Commercial General Liability policies ceased reliably covering pollution claims in Washington. Nearly two decades of documented remediation expenditures — soil excavation, thermal treatment, subsurface investigation, monitoring well installation, and groundwater treatment — trace directly to releases from those pre-1986 fueling operations. With a new cleanup phase launched in 2017, historical carriers who issued CGL policies during the facility's early operational years may be obligated both to recover past remediation costs and to fund the ongoing work.
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.
