This property has a documented history as a bulk fuel distribution terminal going back to 1924. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as the Union Oil Company bulk fuel distribution facility from 1924 until 1978, with aboveground storage tanks and fueling infrastructure documented on site from at least 1929 through 1958. Gasoline-range and diesel-range hydrocarbons, along with lead, have been attributed directly to those historical bulk-plant operations and remain present in groundwater today. Remediation under the Voluntary Cleanup Program consists of passive natural attenuation and in-situ bioremediation, with a Department of Ecology-required quarterly groundwater monitoring program ongoing — most recently sampled in June 2023 — and investigation-derived waste including soil cuttings and purge water continuing to be collected and disposed of as assessment work proceeds. 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.
Bulk fuel distribution at this property began in 1924 and continued for more than five decades before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion. The gasoline-range and diesel-range hydrocarbon and lead contamination documented here traces directly to those pre-1986 Union Oil operations, with no evidence of a discrete recent release as an intervening cause. Remediation costs — bioremediation, long-term quarterly monitoring, and ongoing waste disposal — continue to accrue under a Department of Ecology requirement, and the historical carriers whose CGL policies were in force during the Union Oil operating period may be obligated both to recover past expenditures and to fund the cleanup work still ahead.
