Information Collection Requests (CERCLA 104e)
In January 2008, EPA sent letters to approximately 280 current and former property owners, tenants, and facility operators to help us learn more about the materials handled at these sites, past practices, and known or suspected releases of contamination.
Portland Harbor is located in and along the Willamette River in Portland, Oregon. More than a century of historical industrial use has resulted in Willamette River sediments being contaminated with many hazardous substances, such as heavy metals, polychlorinated biphenyls (PCBs), polynuclear aromatic hydrocarbons (PAH), dioxin/furans, and pesticides.
Portland Harbor was added to the EPA National Priorities List of contaminated sites in December 2000. The initial focus of the study was the heavily industrialized area between Swan and Sauvie Islands. The investigation area currently extends from the Columbia Slough to the Fremont Bridge.

Early Actions - In addition to the harbor-wide investigation, there are several Early Actions underway to clean up individual sites that need more immediate attention. We are currently working with NW Natural for Gasco-Siltronic, the Port of Portland for Terminal 4, Legacy Site Services for Arkema, and the University of Portland for Triangle Park.
