The U.S. Supreme Court has agreed to hear San Francisco's challenge against the Environmental Protection Agency (EPA) regarding water pollution regulations. The case, San Francisco v. EPA (No. 23-753), questions the EPA's authority to set vague and generic pollution prohibitions without specific numerical limitations. San Francisco argues that the EPA's guidelines are insufficiently precise, failing to adequately protect public waters from pollutants. The Supreme Court's decision to take up this case on May 28 could significantly impact the EPA's ability to regulate water pollution and enforce the Clean Water Act. The appeal concerns the EPA's rules on sewage discharge into the Pacific, which San Francisco claims are inadequate for protecting swimmers and bathers.
