Ground-level Ozone Pollution

Connecticut 126 Petition

The Connecticut Department of Energy and Environmental Protection submitted a petition to EPA under section 126 of the Clean Air Act.

The petition requests that EPA make a finding that the Brunner Island Steam Electric Station in York County, Pennsylvania, is emitting air pollutants that significantly contribute to nonattainment or interfere with maintenance of the 2008 ozone national ambient air quality standards (NAAQS) in Connecticut.

On February 7, 2018, the U.S. District Court for the District of Connecticut instructed EPA to hold a public hearing and take final action on this petition by April 8, 2018. More information about EPA's proposed action and the public hearing is available below.
