"The U.S. Environmental Protection Agency announced eight new agreements Monday with parties responsible for cleaning up the Portland Harbor Superfund Site.

The agency said it now has signed cleanup agreements covering more than half of the Superfund site area that requires active cleanup on Portland’s Willamette River. Under the EPA’s cleanup plan, much of the Superfund site will be allowed to recover naturally over time without any active cleanup work.

The agency is still negotiating with other parties that have yet to sign agreements. Federal regulators could issue enforcement orders to require cleanup action."
