Supreme Court Sides With ARTBA Against Vague EPA Permits

What happened: The U.S. Supreme Court March 4 handed ARTBA and its allies a major victory, ruling that the Environmental Protection Agency cannot impose water quality conditions in Clean Water Act permits without clear, enforceable limits. The decision cited the amicus brief filed by ARTBA and two other national associations, which argued that permit holders for construction projects need clarity to meet federal requirements.

Why it matters: The 5-4 ruling in City and County of San Francisco v. EPA should prevent agencies from making permit holders responsible for broader water quality conditions beyond their control. The Court reinforced that the Clean Water Act requires specific limits on discharges, not open-ended mandates, ensuring that permit holders know what is legally required of them. This could reduce legal risks and compliance uncertainty for transportation projects that require stormwater and wastewater permits.

What’s next: ARTBA will monitor how EPA implements the Court’s decision. Prianka Sharma is the contact.
