EPA signed four proposed regulations July 28, 2011, that would revise air pollution limits for the oil and gas industry: a new source performance standard for volatile organic compounds (VOCs); a new source performance standard for sulfur dioxide; an air toxics standard for oil and natural gas production; and an air toxics standard for natural gas transmission and storage. According to EPA, the proposed revisions would lead to a 25 percent reduction in VOC compounds, a 26 percent cut in methane and a 30 percent drop in air toxics. The proposed rule was the result of a consent decree between EPA and environmental groups. WildEarth Guardians v. Jackson, No. 09-89 (D.D.C. 12/11/09). EPA will accept comments on the proposed revisions for 60 days after they are published in the Federal Register.
