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 ( as these information sessions are scheduled.

Portland Tribune: Divvying up the Superfund cleanup

By Steve Law

“As a general concept, I don’t mind the idea of breaking it down into operable units, so that work can be done effectively in one place,” says Jim Robison, chairman of the Portland Harbor Community Advisory Group, EPA’s officially designated citizens panel. The idea of breaking the 10-mile site into smaller Superfund projects has long been discussed, Robison says.

However, he adds, “I wouldn’t want that to be an avenue for them to do less of an effective cleanup.”

Dear Ms. McCarthy,

The proposed cleanup of Portland Harbor is a big win for industry and a bad deal for the public. EPA’s cleanup proposal tackles just 8% of a site area that is 100% toxic. A more aggressive plan is needed to prevent even more harm to human health and the environment. On behalf of all people who rely on the river for food, recreation, employment and culture, I urge the EPA to implement a plan that:

  • Moves quickly and sustainably reduces contaminants causing harm to Willamette and Columbia river resources
  • Includes ongoing monitoring and cleanup upriver and downriver from the site
  • Contributes to healthy fish that are safe to eat for all people
  • Holds polluters accountable for creating a safer Portland Harbor
  • These elements get us closer to the plan our communities deserve.

    And I deserve a clean, safe Portland Harbor.
