The Olympic Pipe Line Company Allen Pump Station, located in Mount Vernon, operated a 16-inch high-pressure petroleum pipeline with documented releases of gasoline and diesel between 1973 and 1983, followed by a major pipeline rupture on September 8, 1988, that released approximately 168,000 gallons of diesel fuel. Cleanup under the Standard Cleanup program has included recovery of over 45,000 gallons of diesel fuel with an estimated 96,600 gallons recovered in total, installation of recovery wells and vapor extraction systems, an oil/water separator, and ongoing quarterly groundwater monitoring with passive LNAPL recovery. Remediation work at the site is ongoing. 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.
Petroleum releases at this facility were documented as early as 1973, more than a decade before occurrence-based Commercial General Liability policies ceased reliably covering pollution claims in 1986. The contamination here — diesel and gasoline from both chronic operational releases and the catastrophic 1988 rupture — traces back to infrastructure and operations that were in place during the pre-1986 policy window. The scale of documented remediation costs, from recovering tens of thousands of gallons of fuel to installing extraction systems and sustaining decades of groundwater monitoring, represents expenditures that historical carriers may be obligated both to recover and to fund going forward.
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.
