The Environmental Protection Agency (the EPA) proposes to establish federal Clean Water Act (CWA) aquatic life criteria for fresh waters under the State of Oregon's jurisdiction, to protect aquatic life from the effects of exposure to harmful levels of aluminum. In 2013, the EPA disapproved the State's freshwater acute and chronic aluminum criteria. The CWA directs the EPA to promptly propose water quality standards (WQS) that meet CWA requirements if a state does not adopt WQS addressing the Agency's disapproval. The State has not adopted and submitted revised freshwater acute and chronic aluminum criteria to the EPA to address the EPA's 2013 disapproval. Therefore, in this notice, the EPA proposes federal freshwater acute and chronic aluminum criteria to protect aquatic life uses in Oregon.
