City and County of San Francisco v. EPA (23-753) Supreme Court Decision
The Supreme Court ruled that Section 1311(b)(1)(C) of the Clean Water Act does not authorize the EPA to include 'end result' provisions in NPDES permits, which would condition compliance on receiving water quality. The Court clarified that it is the EPA's responsibility to determine the steps permittees must take to ensure water quality standards are met.
