This property has a documented history as a landfill predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The Haller Lake Landfill is an abandoned waste disposal site in north Seattle that was already out of operation when the City of Seattle conducted an abandoned landfill survey in 1984. That study assessed whether the site posed public health concerns and outlined a process for requesting followup investigation funding if problems were identified. The site is now classified as awaiting cleanup under Washington's Standard Cleanup program, and no active remediation has commenced. 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.
Waste disposal operations at this landfill predate 1984, placing them squarely within the era when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The cleanup costs this property now faces — site characterization, investigation, and eventual remediation of an abandoned landfill — represent the type of long-tail environmental liability those historical policies were written to cover. Carriers who issued CGL policies during the landfill's active disposal years may be obligated to fund the remediation work ahead.
