  1. U.S. EPA/LADCO Modeling for CAIR:8 hour Ozone and PM2.5 Utility Rules Workgroup Mark Derf IDEM, OAQ June 16, 2005

  2. Nonattainment areas for 8-hour ozone pollution only Nonattainment areas for fine particle pollution only Nonattainment areas for both 8-hour ozone and fine particle pollution Nonattainment Areasfor Ozone and PM2.5 NAAQS

  3. U.S. EPA 8-Hour Ozone Modeling for Final CAIR Rule

  4. U.S. EPA PM2.5 Modeling for Final CAIR Rule

  5. Summary of U.S. EPA’s Modeling:Number of PM2.5 and Ozone Nonattainment Counties

  6. LADCO’s Round 2 Ozone Modeling results - 2009

  7. Explanation of different LADCO modeling scenarios • R2S1 – Controls in place already (i.e. NOx SIP Call, Fuel and Engine Standards, etc) • R2S2 – R2S1 controls plus anticipated controls by 2010 (i.e. CAIR rule) • R2S3A – R2S2 plus VOC controls for 8 point/area source categories in all ozone nonattainment counties in 5 state MRPO region (IL, IN, MI, OH, WI) • R2S3B – R2S2 plus VOC controls for 8 point/area source categories in all ozone nonattainment counties and adjacent counties in MRPO region • R2S4A – R2S3A plus EGU1 controls in MRPO region EGU1 = 2009 emissions of SOx of 0.36 lb/MMBtu and NOx of 0.15 lb/MMBtu • R2S4B– R2S3A plus EGU1 controls in 12-state region (MRPO region plus MN, IA, MO, TN, KY, WV, PA) EGU1 = 2009 emissions of SOx of 0.36 lb/MMBtu and NOx of 0.15 lb/MMBtu • R2S4C– R2S3A plus EGU1 controls in MRPO region EGU2 = 2009 emissions of SOx of 0.24 lb/MMBtu and NOx of 0.12 lb/MMBtu • R2S5– R2S4A plus MACTEC point and area source SOx and NOx controls (i.e. ICI boilers, refineries, cement kilns and iron/steel plants)

  8. U.S. EPA vs. LADCO Modeling Results: Number of Nonattainment Areas

  9. Differences in U.S. EPA and LADCO CAIR Modeling
