On December 1, 2000, the U.S. Environmental Protection Agency (EPA) added the Portland Harbor site to the National Priorities List (NPL), allowing for site cleanup to be addressed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as “Superfund.”
Portland Harbor has a long history of shipping, industrial, and commercial activity because of its key location on the Willamette River. This area of the river also has historical, natural and cultural resource significance. A joint 1997 EPA-DEQ study showed that the river sediments in Portland Harbor are contaminated with DDT and other pesticides, polychlorinated biphenyls (PCBs), and petroleum. Based on this information, EPA designated Portland Harbor as a Superfund Site.
EPA is the lead agency for overseeing the in-water work on contaminated sediments. DEQ is the lead agency for upland source investigation and control work, including shoreline properties, where many of the historic contamination sources are located.
This is an unusually complicated Superfund site, one of the most complex in the entire EPA Superfund program. The site:
