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

The Environmental Protection Agency (EPA) is proposing to deny 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 EPA make a finding that emissions from Brunner Island Steam Electric Station (Brunner Island), located in York County, Pennsylvania, are significantly contributing to nonattainment and interfering 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 proposes to deny the petition because Connecticut has not met its burden to demonstrate that the source emits or would emit in violation of the good neighbor provision such that it will significantly contribute to nonattainment or interfere with maintenance of the 2008 ozone NAAQS in Connecticut. The EPA is further proposing to deny the petition based on the conclusion that the Brunner Island facility does not currently emit nor is it expected to emit pollution in violation of the good neighbor provision for the 2008 ozone NAAQS.
