This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The Spokane Transit Authority bus barn was built in the mid-1980s and has operated continuously as a bus and paratransit maintenance facility, with multiple underground storage tank systems — including a 4,000-gallon automatic transmission fluid tank — installed at the time of construction. Cleanup work has included excavation and removal of the leaking ATF tank; contaminated soil was left in place due to structural constraints and capped under concrete and existing building structures. Remediation is ongoing, with an environmental covenant in place, groundwater monitoring wells installed, and 15-month monitoring cycles scheduled over five years alongside annual cap inspections. 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 ATF contamination here traces directly to a storage tank that was part of the bus barn's original infrastructure when the facility was built in the mid-1980s — a construction window that spans years before 1986, when CGL policies issued to operators like STA did not carry effective pollution exclusions. The remediation costs already incurred at this property — tank excavation and removal, impacted soil capping, covenant establishment — represent expenditures that historical carriers whose policies were in force during those pre-1986 years of operation may be obligated to recover. The multi-year groundwater monitoring program and annual cap inspections that remain ahead add a continuing forward obligation to that same historical exposure.
