Promulgation of Certain Federal Water Quality Standards Applicable to Maine

The Environmental Protection Agency (EPA) is finalizing federal Clean Water Act (CWA) water quality standards (WQS) for certain waters under the state of Maine's jurisdiction, including human health criteria (HHC) to protect the sustenance fishing designated use in waters in Indian lands and in waters subject to sustenance fishing rights under the Maine Implementing Act (MIA). EPA is promulgating these WQS to address various disapprovals of Maine's standards that EPA issued in February, March, and June 2015, and to address the Administrator's determination that Maine's HHC are not adequate to protect the designated use of sustenance fishing for certain waters.
