EPA Issues Ministerial Actions to Implement CSAPR

On 11/21/14, EPA issued two ministerial actions to implement the Cross State Air Pollution Rule (CSAPR) beginning on January 1, 2015.  The implementation of CSAPR will sunset the Clean Air Interstate Rule (CAIR), which is a similar cap-and-trade based program.  CSAPR requires the covered 28 states to limit SO2 and/or NOx emissions from electric generating units (EGUs) on a state-wide basis, with the goal of reducing contributions to fine particulate matter (PM2.5) and ground-level ozone in other states.  CSAPR had been stayed by the D.C Circuit of the U.S. Court of Appeals since 2011, but on 10/23/14, the Court ordered that EPA’s motion to lift the stay be granted.  To reflect the three-year delay in implementation, EPA is issuing final rules that toll the implementation dates to allign with a January 1, 2015 start date for Phase 1 and 2017 for Phase 2.
