Response to June 1, 2016 Clean Air Act Section 126(b) Petition From Connecticut

The Environmental Protection Agency (EPA) is denying a section 126(b) petition submitted by the state of Connecticut pursuant to the Clean Air Act (CAA or Act) on June 1, 2016. The petition requested that the EPA make a finding that emissions from Brunner Island Steam Electric Station (Brunner Island), located in York County, Pennsylvania, significantly contribute to nonattainment and interfere with maintenance of the 2008 ozone national ambient air quality standards (NAAQS) in Connecticut in violation of the good neighbor provision under the CAA. The EPA is denying the petition based on the conclusion that Connecticut has not demonstrated and the EPA has not determined that the Brunner Island facility emits or would emit pollution in violation of the good neighbor provision with respect to the 2008 ozone NAAQS.
