Final Cleanup Plan from EPA

From US EPA 1/6/2017:

Today we released the final cleanup plan, called the Record of Decision, for approximately 10 miles of the Lower Willamette River within the Portland Harbor Superfund Site which runs through the economic heart of Portland, Oregon.

“This is a very strong cleanup plan, thanks in large part to the quality of the public comments we received,” said Dennis McLerran, the EPA’s Regional Administrator for the Pacific Northwest and Alaska. “Under the final plan, we’ll be removing more contaminated sediment sooner, which means risks will be lower and the river will be safer faster. Input from the public, tribes, state and local government, environmental groups and business and industry helped us hone our plan and make it more responsive to people’s concerns. We have been working very closely with Oregon DEQ on the final remedy and with state and EPA leadership. The stage is now set for cleanup work to begin in earnest.”

The Record of Decision addresses contaminated sediments through dredging, capping, enhanced natural recovery, and monitored natural recovery, including removal of over three million cubic yards of contaminated sediments. The ROD also addresses contaminated groundwater that could re-contaminate the river and river banks. About 1,774 acres of the site with lower contaminant levels are expected to recover naturally over time. Active cleanup work at the site is now expected to take as much as 13 years and cost about $1 billion.

At the request of community groups and stakeholders, the EPA plans to host community information sessions to present the details of the final remedy this March. We will post the details on our website (http://go.usa.gov/3Wf2B) as these information sessions are scheduled.
