The U.S. Environmental Protection Agency (EPA) is providing notice that it has responded to 11 petitions for reconsideration of the final rule titled "Oil and Natural Gas Sector: New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants Reviews," published in the Federal Register on August 16, 2012, and seven petitions for reconsideration of subsequent amendments published in the Federal Register on September 23, 2013, and December 31, 2014. The agency previously granted reconsideration of several discrete issues and took final action on reconsideration through documents published in the Federal Register on September 23, 2013, December 31, 2014, August 12, 2015, and June 3, 2016. The Administrator denied the remaining requests for reconsideration in separate letters to the petitioners. The basis for the EPA's action is set out fully in a separate document available in the rulemaking docket.
