The draft permit was circulated for public comment between January 17, 2025, and February 18, 2025. The addendum shows revisions to the draft permit in response to the U.S. Supreme Court’s ruling in City and County of San Francisco, California v. Environmental Protection Agency (2025), which removes end result requirements (e.g., receiving water limitations) in NPDES permits. The draft permit would regulate discharges associated with the extraction and treatment of groundwater impacted by inorganic chemicals, VOCs, per and polyfluoroalkyl substances (PFAS), fuel leak compounds, and other synthetic organic compounds in the San Francisco Bay Region. The San Francisco Bay will accept only comments pertaining to the revisions in this addendum.
