EPA Announces Release of Proposed Plan for Portland Harbor

The Proposed Plan for the Portland Harbor Superfund Site is now available for review and public comment.

The Proposed Plan presents EPA’s preferred cleanup alternative, Alternative I, which reduces risks to human health and the environment to acceptable levels by dredging or capping 291 acres of contaminated sediments and 19,472 lineal feet of contaminated river bank, followed by 23 years of monitored natural recovery. The preferred alternative also includes disposal of dredged sediment in an on-site confined disposal facility and upland landfills. This Alternative will cost approximately $746 million and take 7 years of construction in the river.

The Proposed Plan also describes other alternatives that were considered and the criteria EPA used to compare the alternatives, including estimated costs and construction timelines.

Site Summary

The Portland Harbor Superfund Site in Portland, Oregon is located within the lower Willamette River from the Broadway Bridge (RM 11.8) to Kelly Point Park (RM 1.9) and is the result of decades of industrial use along the Willamette River. The Portland Harbor Superfund Site was added to EPA's National Priorities List in December 2000.

Water and sediment at the Portland Harbor Site are contaminated with many hazardous substances, including polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), dioxins/furans, pesticides and heavy metals. These compounds have been found to be harmful to people and the environment. Health risks at the site are great enough for cleanup to be needed under the Superfund law.

EPA and the Oregon Department of Environmental Quality are working with potentially responsible parties to clean up contaminated sediment and control sources of contamination.
