Final Record of Decision (ROD) for Portland Harbor

The EPA has issued the Record of Decision that selects the remedy for cleanup at the Portland Harbor Superfund Site. The Selected Remedy is a final action for the in-river portion of the Site from approximately river mile 1.9 to 11.8.

We have selected Alternative F Modified as the final remedy.

Alternative F Modified is designed to reduce risks to human health and the environment to acceptable levels and actively remediate (using dredging, capping, enhanced natural recovery, and monitored natural recovery) 394 acres of contaminated sediments and 23,305 lineal feet of river bank. This final remedy will cost approximately $1.05 billion and take about 13 years to complete.

EPA received input from over 5,300 commenters between June 9 and September 6, 2016 on the Proposed Cleanup Plan for the Portland Harbor Superfund Site. We thank everyone who submitted comments. All comments that were submitted to EPA are available in the Administrative Record. Our responses to comments are included in the Responsiveness Summary in Part 3 of the ROD.

In March 2017, EPA presented the details of the final remedy at three in-person community information sessions and one live webinar. More information about these sessions is available on the Community Resources page.

The ROD and related documents are listed below:

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.
