This property has a documented history as a bulk fuel distribution terminal going back to 1968. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The Phillips 66 Renton Terminal has operated as an active bulk petroleum distribution facility since 1968, receiving, storing, loading, and dispatching gasoline, diesel fuel, kerosene, ethanol, and additives from a tank farm with a loading rack for tanker trucks. Cleanup activities have included multi-year groundwater and product extraction using recovery trenches, vacuum trucks, and dual-phase extraction systems, with recovered groundwater treated by oil/water separators and carbon vessels. Soil vapor extraction systems treat hydrocarbon vapors through thermal oxidizers, and pilot tests have demonstrated significant hydrocarbon mass removal and recovery of thousands of gallons of groundwater. Ongoing monitoring, soil containment measures, and evaluation of in-situ enhanced biodegradation are continuing 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.
This terminal began bulk petroleum storage and distribution operations in 1968 — nearly two decades before 1986, when occurrence-based Commercial General Liability policies were replaced by forms carrying effective pollution exclusions. The first documented release was recorded in 1986, at the precise boundary of the pre-exclusion policy era, and the contamination originates from above-ground storage tank failures tied directly to those long-running historical operations. The multi-system remediation infrastructure now in place — dual-phase extraction, soil vapor extraction with thermal oxidation, and sustained groundwater monitoring — represents the kind of ongoing cleanup expenditure that pre-1986 CGL carriers may be obligated both to recover and to fund as remediation continues.
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.
