This property has operated as a gasoline service station since at least 1966, when Humble Oil & Refining Company maintained a plot plan for the site. The facility currently consists of a station building, two canopy-covered pump islands, underground storage tanks containing gasoline, and a separate used-oil UST. Cleanup under the Standard Cleanup program has included soil removal, installation of 11 monitoring wells, and ongoing quarterly purging and disposal of contaminated groundwater, with aquifer pilot testing and groundwater treatment planned. 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 hydrocarbon contamination at this site traces to underground storage tank operations that were already in place by 1966 — two full decades before occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The remediation costs documented here — monitoring-well installation, ongoing groundwater extraction and disposal, and the planned aquifer testing and treatment system — represent both past expenditures and future obligations that historical carriers who wrote CGL coverage during that pre-1986 operational window may be obligated to fund.
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.
