This WSDOT-owned highway interchange — where SR 16 passes under I-5 in Tacoma — has been in continuous operation since 1950, when SR 16 (then Primary State Highway 14) began serving as the link to the Tacoma Narrows Bridge. A tanker truck rollover accident at the interchange released petroleum products into the surrounding environment, with contaminated flow directed via a shoulder-side ditch toward a storm drain discharging into the Thea Foss Waterway. Petroleum contamination has been confirmed in both groundwater and surface water, and the site overlies the Central Pierce County Sole Source Aquifer with municipal production wells within two miles. The site is currently awaiting cleanup under Ecology's Standard Cleanup program. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
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.
This transportation corridor has operated continuously since the 1950s — more than three decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The petroleum contamination now confirmed in groundwater and surface water above a sole-source aquifer will require remediation whose costs have yet to be incurred. Historical CGL policies issued to the facility's operators during that pre-1986 window may be obligated to fund the investigation, design, and cleanup work that lies 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.
