This property has a documented history as a landfill going back to 1951. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The Arlington Marysville Landfill began operating as a burning dump around 1951, accepting refuse, septic tank waste, and industrial wastes over the course of nearly three decades. The facility experienced a fire in 1977 and was formally closed in August 1980, when the site was covered with two feet of soil as a low-permeability containment measure. A preliminary assessment was conducted in 1985, and the site remains enrolled in the Standard Cleanup program awaiting active remediation. 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 at this landfill — including industrial wastes accepted over decades of operation — began more than thirty years before 1986, when occurrence-based Commercial General Liability policies were the prevailing form of liability coverage and carried no effective pollution exclusion in Washington. The contamination attributable to the site's history of industrial and septic waste disposal is precisely the type of slow, diffuse release those pre-1986 policies were written to address. Investigation and remediation costs that lie ahead for this closed landfill could plausibly be funded by historical carriers whose policies were in force during the decades of active disposal operations.
