This property has a documented history as a gasoline service station going back to 1969. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
Former Exxon Station 77001 operated as a gasoline service station in Seattle with multiple underground storage tanks dispensing regular and premium unleaded fuel, with UST installation dating to approximately 1969. Remediation under the Standard Cleanup program has included UST removals in 1993 and earlier, bulk soil removal, disposal of drummed soil cuttings and rinsate, and operation of an on-site Groundwater Pump and Treat system in 2011. A remediation infrastructure of eight air sparge wells and four injection wells has been established, with additional injection wells installed in 2012, and quarterly groundwater monitoring has been ongoing since 1991. Cleanup at this site is ongoing. 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.
The contamination at this property — petroleum hydrocarbons and lead in soil and groundwater — traces to gasoline storage and dispensing operations that began in 1969, nearly two decades before 1986. The presence of lead in groundwater strongly implies the use of leaded gasoline, which was phased out before 1986, anchoring the contamination origin squarely within the pre-1986 policy window when occurrence-based CGL policies had no effective pollution exclusion. Those historical carriers may be obligated to recover documented remediation costs — UST removals, soil excavation, groundwater treatment, long-term monitoring — and to fund continued cleanup going forward.
