This property has a documented history as a gasoline service station going back to 1964. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property was redeveloped as an automobile fueling and repair facility in approximately 1964, with underground storage tanks dispensing gasoline — including a 10,000-gallon leaded gasoline UST that failed tightness testing in 1988. Cleanup under the Voluntary Cleanup Program has included excavation of multiple USTs, groundwater dewatering, operation of a soil vapor extraction and air sparge system that recovered 1,487 pounds of hydrocarbons, and in-situ remedial injections of ORC and BOS-200 to enhance biodegradation. Semi-annual groundwater monitoring has been ongoing since 2004, and cleanup work continues. 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.
Petroleum contamination at this site traces to gasoline storage and dispensing operations that began in 1964 — more than two decades before occurrence-based CGL policies ceased reliably covering pollution claims. The documented remediation expenditures here — tank removals, vapor extraction, groundwater treatment, chemical injections, and over twenty years of monitoring — represent costs tied directly to releases from those pre-1986 operations. Historical carriers who wrote CGL policies during the 1964-to-1986 operating window may be obligated both to reimburse past cleanup costs and to fund the remediation still underway.
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.
