GIS Owners in California Must Comply With sf6 gas Regulation

Jan 11, 2019 · Since 2011, the California Air Resources Board (CARB) has regulated sulfur hexafluoride (sf 6) emissions from gas-insulated switchgears (GIS). CARB’s sf 6 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 sf 6 requirements.
