  • GIS Owners in California Must Comply With SF6 Regulation

    Jan 11, 2019 · Since 2011, the California Air Resources Board (CARB) has regulated sulfur hexafluoride (SF6) emissions from gas-insulated switchgears (GIS). CARB’s SF6 Regulation applies to all entities that own GIS, including many entities that do not otherwise emit and report greenhouse gas (GHG) emissions such as wind farms, solar parks, and geothermal plants. Accordingly, some companies may not have realized that they are subject to the SF6 requirements.
