CSAPR

  • Promulgated July 2011 Under Good Neighbor

Provisions of CAA

  • 28 States to Reduce Power Plant Emissions
  • Emissions Cross State Lines Contribute to O3 (1997

NAAQS) and Fine Particle (2006 NAAQS) Pollution

  • Three separate cap-and-trade programs
  • NOX O3 Season
  • NOX Annual
  • SO2 Annual

CSAPR

  • D.C. District Court
  • December 30, 2011 stayed CSAPR
  • August 21, 2012 vacated CSAPR (split 3-judge panel)
  • U.S. Supreme Court Reviewed District Court’s

Decision December 10, 2013

  • Supreme Court Decision Expected Second Half 2014

CSAPR

Ramifications of Supreme Court decision

  • Do we need CSAPR?
  • Confusion and chaos?
  • SO2 and NOx emission reductions will already have

been achieved through CAIR, ARP, and other emission reduction programs for eastern U.S., although with some state-by-state differences

  • Effect of New NAAQS?
  • BART and SIPs
