Deschutes River TMDL: EPA Action

NWEA Lawsuit Forces EPA Action on Deschutes River Clean-Up Plan

After failing to either approve or disapprove the Washington Department of Ecology’s Deschutes River TMDL clean-up plan for two and a half years, EPA partially approved and partially disapproved the plan in response to the court order in the NWEA case.  EPA approved most of the clean-up plans for temperature pollution but it disapproved those for dissolved oxygen, pH, fine sediment, and bacteria.  EPA is now on the hook to develop replacements for those plans it disapproved.  The Clean Water Act gives the agency 30 days.
