This property has a documented history as a dry cleaning facility going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
A dry cleaning facility operated on the western portion of this Seattle property from the early 1950s until 1993, when it was shut down following a fire. Contamination from historical releases of tetrachloroethylene (PCE) and associated daughter products was identified in 1990, triggering remediation that has continued for more than three decades under the Voluntary Cleanup Program. Cleanup activities have included 4,400 cubic yards of soil excavation, an air sparging and soil vapor extraction system that operated from 1998 to 2010, subslab depressurization, and ongoing In Situ Chemical Reduction and In Situ Bioremediation treatments involving thousands of gallons of injected reagent. 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 PCE contamination at this property originated from dry cleaning operations that began in the early 1950s — more than three decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion in Washington. The contamination is explicitly characterized as the product of historical releases during those ongoing operations, not a discrete post-1986 event. The documented remediation trail here — decades of soil excavation, vapor extraction, and active in-situ treatment — represents expenditures historical carriers may be obligated both to recover and to fund as injections and monitoring continue.
