This property has a documented history as a gasoline service station going back to 1924. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
A gasoline tank was documented at this Olympia property as early as 1924 on Sanborn fire insurance maps, and by 1946 the site was operating as a "Gas & Oil" supplier — an automobile dealership and service shop with an open-front garage where vehicles pulled in from Capitol Way to dispense fuel. Underground storage tanks in the northern portion of the property are the identified source of historical petroleum contamination; the tanks were presumed removed during site redevelopment in 1972. Active investigation is ongoing, with waste liquids from current fieldwork stored in 55-gallon drums pending disposal, and future remediation — soil excavation and installation of an air sparge and vapor extraction system — has been 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.
Petroleum contamination at this property originates from underground storage tanks that operated for roughly five decades before 1986, spanning an era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The historical carriers who issued CGL coverage during the site's operational window — from the 1920s through the 1972 redevelopment — may be obligated both for the investigation costs already incurred and for the soil excavation, air sparging, and vapor extraction expenditures the remediation plan calls for going forward. The documented link between contamination and former USTs associated with pre-1986 fuel-dispensing operations establishes the causal chain that historical insurance recovery requires.
