This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
This site is the groundwater plume attributable to Unocal's former Seattle Marketing Terminal, a bulk petroleum storage and distribution facility adjacent to 3131 Elliott Ave in Seattle. A Level II environmental assessment conducted in May 1991 was designed to determine whether petroleum contamination from the terminal had migrated onto the neighboring parcel; soil and groundwater sampling at 3131 Elliott Ave returned no detectable petroleum hydrocarbons, and the assessment concluded that no further investigation of that parcel was warranted. The plume associated with the terminal itself has not been remediated and the site remains categorized as Awaiting Cleanup under the Standard Cleanup program. 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.
Unocal's Seattle Marketing Terminal was already designated 'former' at the time of the 1991 assessment, placing its active bulk petroleum operations in a period that predates 1986 — the relevant threshold for occurrence-based CGL coverage. A facility of this type, storing and distributing petroleum products at scale in a major urban market, would have carried substantial commercial liability policies throughout its operating years, and those policies are the natural mechanism for recovering the investigation and remediation costs this plume now requires.
