This property has a documented history as a gasoline service station going back to 1970. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The Wagon Wheel Market property in Spanaway has operated as a fueling station and convenience store with underground storage tanks dispensing gasoline and diesel fuel for retail sale. Contamination from a leaking gasoline tank was discovered in 1990, triggering cleanup activities under the Voluntary Cleanup Program that have spanned nearly three decades. Remediation included removal of two USTs, operation of groundwater pump-and-treat and soil vapor extraction systems, enhanced bioremediation through ORC injection, and treatment of over 22.7 million gallons of contaminated groundwater between 1991 and 1992. Although a No Further Action letter was issued in 2011, elevated contaminant levels were detected again in 2017, and the site remains in active cleanup status with ongoing groundwater monitoring. 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 underground storage tanks at this property are estimated to have been installed around 1970, and lead detected in soil at the removed tank locations is a direct indicator of pre-1986 gasoline use — placing the contamination origin squarely within the era of occurrence-based CGL policies that carried no effective pollution exclusion. Nearly three decades of documented remediation expenditures — tank removals, pump-and-treat operations, vapor extraction, bioremediation, and long-term monitoring — represent costs that historical carriers who issued policies during those pre-1986 operations may be obligated both to recover and to fund as cleanup continues.
