This property has a documented history as a public works and maintenance facility going back to 1969. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The Seattle Public Utilities Operations Center has served as a municipal maintenance and vehicle-servicing yard for the City of Seattle Water Department, with underground storage tanks inferred to have been installed by 1969. Cleanup activities from 1991 through 2017 have included removal of multiple USTs (1,000-gallon and 8,000-gallon capacities), excavation of over 300 tons of petroleum-impacted soil across several phases, recovery of thousands of gallons of contaminated groundwater, and ongoing monitoring-well installation and sampling. Contamination sources include leaking underground storage tanks, hydraulic hoist failures, and piping leaks associated with decades of facility operations. 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 traces to underground storage tanks and hydraulic equipment that were installed and operated well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. More than two decades of documented remediation expenditures — tank removals, multi-phase soil excavation, groundwater recovery, and long-term monitoring — have been incurred to address releases tied directly to those pre-1986 operations. With cleanup still underway, the City's historical CGL carriers may be obligated both to recover past remediation costs and to fund the work that remains.
