In San Francisco v. Environmental Protection Agency (EPA), will the Supreme Court rule that the EPA cannot impose the generic prohibitions in San Francisco's discharge permit under the Clean Water Act without identifying specific limits to which their discharges must conform?

San Francisco has sued the EPA over what it calls "generic prohibitions" in its National Pollutant Discharge Elimination System (NPDES) permit for wastewater (SCOTUSblog, EPA - NPDES Permit Basics, Newsweek). In July 2023, the Ninth Circuit found for the EPA, and this appeal followed (Frost Brown Todd). The Supreme Court is expected to hand down its decision in its 2024 term, but if it does not, the question will close as "No." If the Court decides this case without addressing this question's particular issue of law, the question will close as "No." The Court ruling for San Francisco as to any of the prohibitions will count as a "Yes."
