On December 15, 2016, EPA extended by six months the deadlines to respond to petitions submitted by the states of Delaware and Maryland under section 126 of the Clean Air Act.
The petition from Delaware requests that EPA make a finding that the Homer City power station located in Indiana County, Pennsylvania, is emitting air pollutants that significantly contribute to nonattainment or interfere with maintenance of the 2008 national ambient air quality standards (NAAQS) for ozone and the 2015 ozone NAAQS in Delaware.
The petition from Maryland requests that EPA make a finding that 36 electric generating units located in the states of Indiana, Kentucky, Ohio, Pennsylvania, and West Virginia are emitting air pollutants that significantly contribute to nonattainment or interfere with maintenance of the 2008 and the 2015 ozone NAAQS in Maryland.
