Fluoride Action Network | California is first to regulate

New Regulations For 2012Actions at The Federal LevelConvergence of EPA and California InitiativesBy virtue of a vote of its Air Resources Board in February, California became the first jurisdiction to formally regulate sf6 gas emissions from electrical equipment in the United States. Starting in 2012, equipment containing Sulfr hexafluoride will be allowed to leak no more than 10 percent of its total capacity into the atmosphere. The cap will decline each year until it reaches the ultimate target of 1 percent of the gaz sf6 capacity in 2020 – which equates to a 70 percent reduction of Sulfr hexafluoride emissions from all electric utility applications in the state. The regulations exempt several other uses of sf 6, including medical uses, nuclear power plant testing and equipment calibration. Everyone else will be prohibited from purchasing, selling, owning or using Sulfr hexafluoride in the state after January 2011.
