This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
Auburn Shell operated as a gasoline fueling center at this Auburn location with multiple underground storage tanks dispensing fuel prior to 1990. In April 1990, four USTs were removed after one failed a tightness test, accompanied by soil excavation and the installation of a vapor extraction system; a second round of soil removal in 1996 brought the total to 560 cubic yards of contaminated material across both events. In-situ bioremediation via Oxygen Release Compound injections was conducted in 1997–1998 and again in 2006, and groundwater monitoring and natural attenuation have continued since 1997 with further monitoring recommended. 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 gasoline release at this site originated from underground storage tanks installed and operated well before 1986 — the year occurrence-based Commercial General Liability policies gave way to forms with effective pollution exclusions. The documented remediation record here spans more than three decades: four UST removals, 560 cubic yards of excavated soil, a vapor extraction system, multiple rounds of in-situ bioremediation, and ongoing groundwater monitoring. Historical CGL carriers whose policies covered Auburn Shell's fueling operations during the pre-1986 window may be obligated to recover costs already incurred and to fund the monitoring program going forward.
