  1. Clean Air Interstate and Visibility Rules Update Presentation for NARUC Winter Meeting 2008 Joint ERE-Electricity Committees Session Clean Air Markets Division U.S. Environmental Protection Agency Office of Air and Radiation February 19, 2008

  2. Clean Air Interstate and Visibility Rules States Covered in Clean Air Interstate Rule (CAIR) and Clean Air Visibility Rule (CAVR) for SO2 and NOX CAVR Outside of CAIR Region – BART controls or States can create trading programs Note: On February 8, 2008, the U.S. Court of Appeals issued a decision vacating the Clean Air Mercury Rules (CAMR) and thereby suspending the program that allowed emissions trading. EPA is now evaluating the Court’s decision.

  3. Advanced Pollution Controls for SO2 and NOX that Are Installed, Committed to, and Projected for Coal-fired Generation Gigawatts Gigawatts Projected 2020 SCR & Scrubber Projected 2015 Projected 2020 SCR & Scrubber Projected 2020 Projected 2015 SCR & Scrubber Committed 2007-2010 Projected 2015 Projected 2010 Committed 2007-2010 SCR SCR SCR Committed 2007-2010 Installed by 2006 Scrubber Scrubber Scrubber Installed by 2006 Installed by 2006 The left bar graph provides the amount of coal-fired steam capacity that has either Scrubbers, SCRs, or both technologies in place by 2006 (from EPA’s NEEDs database 2007), committed to be operational from 2007-2010 (largely from 2007 survey results), and forecasted by EPA (using IPM) to be operating by the end of 2010, 2015, and 2020, respectively. In 2006, 2010, 2015, and 2020, the total coal-fired capacity is 318 GW, 320 GW, 335 GW and 373 GW, respectively. The right bar graph shows for 2010, 2015, and 2020 the amount of coal-fired steam capacity with Scrubbers, SCRs, or both controls. Both bar graphs included existing and new generation capacity. Virtually all coal-fired generation units have advanced particulate control systems. Some additional units will have SNCR controls and EPA expects virtually all of these units to have NOx combustion controls and the vast majority of the “nonscrubbed” units to use lower sulfur coals. EPA’s analysis covered CAIR, CAMR, and CAVR; without CAMR there would likely be a few less scrubber installations over time.

  4. CAIR’s and CAVR’s Addition to Existing Programs Should Lead to Much Cleaner Air Areas Currently Designated as Nonattainment for PM2.5 and/or 8-Hour Ozone (April, 2005) Areas Projected to Meet the PM2.5 and 8-Hour Ozone Standards in 2020 with CAIR/CAVR and Some Current Rules, Absent Additional Local Controls ---------- Area Count Both PM and Ozone Nonattainment 3 PM Only Nonattainment 13 Ozone Only Nonattainment 7 Nonattainment areas projected to attain 106
