This property has a documented history as a gasoline service station going back to 1974. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as Chevron Service Station 94998, a retail fuel outlet with underground storage tanks and dispenser islands at 1501 Auburn Way N in Auburn. Cleanup activities under the Voluntary Cleanup Program have included a 1999 excavation of former USTs and contaminated soil, followed by extensive groundwater monitoring and sampling from 2010 through 2014 addressing petroleum hydrocarbons and light non-aqueous phase liquid (LNAPL) in the subsurface. The station is no longer in operation, and remediation efforts — part of Chevron's broader multi-site independent remedial action program — remain 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.
Petroleum contamination at this site originated from underground storage tanks estimated to have been installed in the mid-1970s, well before 1986 when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. More than two decades of documented remediation expenditures — tank and soil excavation, long-term groundwater monitoring, LNAPL management, and continued VCP enrollment — trace directly to releases from those pre-1986 fueling operations. Historical carriers who issued CGL policies during the station's early operational years may be obligated both to reimburse costs already incurred and to fund the cleanup work that remains ahead.
