DEQ revising proposed pollution limits for Tualatin River

Agency seeks public comment on plan

State environmental regulators have proposed revised pollution limits for the Tualatin River.

The Oregon Department of Environmental Quality has released proposed new Total Maximum Daily Load levels, as required by the Clean Water Act of 1972.

The load levels restrict the amount of phosphorus and other substances that can be released into the river, affecting, among impacts, the treated sewer discharges into the river by Clean Water Services, a sewer authority in Washington County.

The DEQ is seeking public comments on the new plan, which can be read at:

A public hearing will held at 6 p.m. Nov. 16 in Aloha. Written comments can be submitted until Wednesday, Nov. 30.
