This property has a documented history as a dry cleaning facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
Northwest Cleaners operated as a dry cleaning tenant within the Highland Park Retail Center at this Bellevue property, releasing tetrachloroethylene (PCE), trichloroethylene (TCE), and related chlorinated volatile organic compounds into the underlying soil and groundwater. Remediation under the Voluntary Cleanup Program has included the excavation and off-site disposal of 5,000 tons of contaminated soil in September 2022, multiple rounds of in-situ chemical injection using GeoForm®, ELS®, and DHC inoculant, vapor intrusion sampling, and planned sub-slab coating, alongside monitored natural attenuation and groundwater monitoring ongoing since at least 1997. The former retail buildings on the property have since been demolished to facilitate redevelopment. 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 and TCE contamination documented at this site originated from dry cleaning operations that predated 1986 by definition: groundwater impacts were already under active monitoring in April 1997, well after the releases that caused them had occurred. Occurrence-based Commercial General Liability policies issued to the operators during that pre-1986 window carried no effective pollution exclusion under Washington law and remain enforceable today. The scope of documented remediation here — 5,000 tons of excavated soil, in-situ chemical treatment, vapor intrusion controls, and decades of continuing groundwater monitoring — represents expenditures that historical carriers may be obligated both to recover and to fund going forward.
