Cross-State Air Pollution Rule (CSAPR)
On August 21, 2012, the U.S Court of Appeals for the DC Circuit issued a ruling vacating the U.S. Environmental Protection Agency's (EPA) Cross State Air Pollution Rule (CSAPR). On October 5, 2012, the asked the full Court for a rehearing of that decision, staying the Court's ruling. On January 24, 2013, the Court denied the EPA's request for a rehearing. On March 29, 2013, the EPA petitioned the U.S. Supreme Court to review the D.C. Circuit Court’s decision on CSAPR. The EPA's Clean Air Interstate Rule (CAIR) remains in effect. EPA is conducting outreach with states on the next steps in addressing the transport of air pollution across state lines.
