Extension of Deadline for Action on the November 28, 2016 Section 126 Petition From Delaware

In this action, the Environmental Protection Agency (EPA) is determining that 60 days is insufficient time to complete the technical and other analyses and public notice-and-comment process required for our review of a petition submitted by the state of Delaware pursuant to section 126 of the Clean Air Act (CAA). The petition requests that the EPA make a finding that Conemaugh Generating Station, located in Indiana County, Pennsylvania, emits air pollution that significantly contributes to nonattainment and interferes with maintenance of the 2008 and 2015 ozone national ambient air quality standards (NAAQS) in the state of Delaware. Under section 307(d)(10) of CAA, the EPA is authorized to grant a time extension for responding to a petition if the EPA determines that the extension is necessary to afford the public, and the agency, adequate opportunity to carry out the purposes of the section 307(d) notice-and-comment rulemaking requirements. By this action, the EPA is making that determination. The EPA is, therefore, extending the deadline for acting on the petition to no later than August 3, 2017.
