EPA announced proposed federal baseline water quality standards for waterbodies on Indian reservations that do not have Clean Water Act standards, ensuring protections for over half a million people living on Indian reservations as well as critical aquatic ecosystems. Fifty years ago, Congress established a goal in the Clean Water Act (CWA) that waters should support fishing and swimming wherever attainable. All states and 47 Tribes have established standards consistent with that goal. However, the majority of U.S. Tribes with Indian reservations lack such water quality standards. This proposal would extend the same framework of water quality protection that currently exists for most other waters of the United States to waters of over 250 Tribes and is the result of decades of coordination and partnership with Tribes.
