The EPA is extending by 6 months the deadline for EPA to take action on a petition submitted by Warrick County, Indiana and the Town of Newburgh, Indiana under section 126 of the Clean Air Act (CAA). The petition requests that EPA make a finding that a power plant (Cash Creek) proposed to be built in Henderson County, Kentucky will emit air pollutants that will significantly contribute to Warrick County and Newburgh, Indiana's nonattainment with the national ambient air quality standards (NAAQS) for ozone and fine particulate matter, or will significantly interfere with Warrick County and Newburgh, Indiana's ability to maintain its attainment of those standards. The petition requests that EPA establish emission limitations for the proposed power plant as a result of those findings. Under the CAA, EPA is authorized to grant a time extension for responding to the petition if EPA determines that the extension is necessary, among other things, to meet the purposes of the CAA's rulemaking requirements. By this action, EPA is making that determination.
