EPA Acts on Ozone
The U.S. Environmental Protection Agency has published notice that it has denied a petition from the Sierra Club requesting that EPA redesignate as nonattainment 57 areas with 2012 design values violating the 2008 national ambient air quality standards for ozone. The petition also requests that the EPA set specific boundaries for the areas. The EPA Administrator denied the petition in letters to the signatories of the petition dated August 14, 2014. The letters explain EPA's reasons for the denial and are available in the rulemaking docket.

  • EPA has also published three final documents titled Policy Assessment for the Review of the Ozone National Ambient Air Quality Standards; Health Risk and Exposure Assessment for Ozone; and Welfare Risk and Exposure Assessment for Ozone. These three documents have been prepared by EPA as part of the Agency's ongoing review of its Clean Air Act National Ambient Air Quality Standards.
