This property has a documented history as a landfill going back to 1958. Historical insurance policies issued during those prior operations and through 1986 could help fund the cleanup that lies ahead.
Originally known as the Sellwood Dump, this landfill operated from the late 1950s through December 1970, receiving decades of buried waste that has since contaminated multiple environmental media across the property. Sampling from 1987 through 2007 confirmed PCBs, metals, pesticides (DDT, DDD, DDE), and PAHs in surface water and sediment at Wapato Marsh, with groundwater and leachate seeps migrating from the landfill body. Oregon DEQ rescinded a 1996 No Further Action determination in 2009 after updated risk-based standards revealed ongoing threats to aquatic life, and the City of Portland's Bureau of Environmental Services completed an interim seep removal action using granular activated carbon in October 2019. As of March 2025, DEQ has requested additional monitoring and risk evaluation, but further work remains deferred pending funding. That history could support an insurance coverage claim against the carriers who issued policies more than 40 years ago — coverage that could help fund the cleanup ahead.
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 Oregon — and those policies may provide coverage that remains enforceable today. 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 contamination at this property traces to landfill operations conducted from the late 1950s through December 1970, placing the full history of waste disposal decades before 1986. With Oregon DEQ's rescission of the earlier No Further Action determination and its March 2025 request for additional monitoring and risk evaluation, the investigation, remediation, and long-term environmental monitoring costs this property still faces are substantial future obligations that historical pre-1986 carriers may be obligated to fund.
