Recognizing the importance of supporting California’s clean energy transition and protecting California communities, Governor Gavin Newsom partnered with legislative leaders to pass a package of climate legislation—including Senate Bill 1137 (SB 1137).   

On September 16, 2022, Governor Gavin Newsom signed SB 1137 (Gonzalez, Chapter 1, Statutes of 2022​) into law. This bill prohibits the issuance of well permits and the construction and operation of new production facilities within a health protection zone of 3,200 feet from a sensitive receptor. In addition, the bill establishes strict engineering controls to be implemented by existing operations within the health protection zone.
