The EPA is extending by 6 months the deadline for EPA to take action on a petition submitted by the New Jersey Department of Environmental Protection (NJDEP). The petition requests that EPA make a finding under the Clean Air Act (CAA) that the coal-fired Portland Generating Station in Upper Mount Bethel Township, Northampton County, Pennsylvania, is emitting air pollutants in violation of the provisions of the CAA. Under the CAA, EPA is authorized to grant a time extension for responding to the petition if EPA determines that the extension is necessary, among other things, to meet the purposes of the CAA's rulemaking requirements. By this action, EPA is making that determination.
