This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The D Street Petroleum site in Tacoma has operated as a bulk petroleum storage and distribution facility serving major oil companies — Mobil, British Petroleum, Unocal/76 Products, and Tosco among its historical operators, with Phillips 66 currently active on the property. Cleanup activities formalized under a Consent Decree, with site-specific cleanup levels established in 1991, have included groundwater recovery and treatment, Soil Vapor Extraction, and an engineered treatment building; the active remedial system was decommissioned in 2006. The site now operates under a monitored natural attenuation program with ongoing groundwater monitoring and purge water disposal. 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 petroleum storage and distribution at this property involved multiple successive operators across decades of pre-1986 activity — each of whom would have carried occurrence-based Commercial General Liability policies at a time when those policies had no effective pollution exclusion. The Consent Decree and cleanup levels documented as early as 1991 confirm that the contamination originates from operational releases tied to that pre-1986 window. With Mobil, BP, Unocal/76 Products, and Tosco all appearing in the chain of operators, this site presents an unusually broad field of historical carriers whose policies may remain obligated to fund the long-running remediation costs.
