CAIR Reduces Indiana’s Emissions

• By 2015, CAIR will help Indiana sources reduce emissions of sulfur dioxide (SO₂) by 452,000 tons or 56 percent.

• By 2015, CAIR will help Indiana sources reduce emissions of nitrogen oxides (NO_x) by 177,000 tons or 68 percent.

CAIR Helps Indiana and its Neighbors

• Because air emissions travel across state boundaries, reducing the emissions from sources in Indiana also will reduce fine particle pollution and ground-level ozone pollution in other areas of the country.

• Currently, Indiana sources significantly contribute to fine particle pollution in 10 other states:
      Pennsylvania, West Virginia, North Carolina, Illinois, Kentucky, Ohio, Alabama, Georgia, Tennessee & Michigan

• Currently, Indiana sources also significantly contribute to ground-level ozone pollution in 3 other states:
      Ohio, Wisconsin & Michigan

• Indiana’s fine particle air quality will improve because of reductions of SO₂ and NO_x in:
      Alabama, Georgia, Illinois, Iowa, Kentucky, Michigan, Minnesota, Missouri, Ohio, Tennessee & Wisconsin

CAIR Makes Indiana’s Air Cleaner

• CAIR helps Indiana meet and maintain the National Ambient Air Quality Standards (NAAQS) for ground-level ozone and fine particle pollution.

• SO₂ and NO_x contribute to the formation of fine particles (PM), and NO_x contributes to the formation of ground-level ozone.

• Areas meeting the NAAQS are in attainment. Those areas not meeting the standards are known as “nonattainment areas.”

    Fine Particle Pollution

• 18 Indiana counties were designated nonattainment for EPA’s health-based standards for fine particle pollution.

• CAIR will help bring six of those counties into attainment by 2010:
      1. Dubois County Evansville, IN-KY Area
      2. Gibson County (P) Evansville, IN-KY Area
      3. Pike County (P) Evansville, IN-KY Area
      4. Spencer County Evansville, IN-KY Area
      5. Vanderburgh County Evansville, IN-KY Area
      6. Warrick County Evansville, IN-KY Area

• Existing Clean Air Act programs will help bring one more county into attainment by 2010:
      1. St. Joseph County Elkhart, IN Area

• CAIR will help reduce particle pollution in all of the remaining nonattainment counties:
      1. Lake County Chicago-Gary-Lake County, Il-IN Area
      2. Porter County Chicago-Gary-Lake County, Il-IN Area
      3. Dearborn County (P) Cincinnati-Hamilton, OH-KY-IN Area
      4. Hamilton County Indianapolis, IN Area
      5. Hendricks County Indianapolis, IN Area
      6. Johnson County Indianapolis, IN Area
      7. Marion County Indianapolis, IN Area
      8. Morgan County Indianapolis, IN Area
      9. Clark County Louisville, KY-IN Area
      10. Floyd County Louisville, KY-IN Area
      11. Jefferson County (P) Louisville, KY-IN Area

    Ground-level Ozone

• At the end of 2004, 24 Indiana counties were designated nonattainment for EPA’s health-based standards for ground-level ozone pollution.

• Existing Clean Air Act programs will bring all of these counties into attainment by 2010:
      1. Lake County Chicago-Gary-Lake Co. IL-IN Area
      2. Porter County Chicago-Gary-Lake Co. IL-IN Area
      3. Dearborn (P) County Cincinnati-Hamilton OH-KY-IN Area
      4. Vanderburgh County Evansville, IN-KY Area
      5. Warrick County Evansville, IN-KY Area
      6. Allen County Fort Wayne, IN Area
      7. Greene County Greene Co., IN Area
      8. Boone County Indianapolis Area
      9. Hamilton County Indianapolis Area
      10. Hancock County Indianapolis Area
      11. Hendricks County Indianapolis Area
      12. Johnson County Indianapolis Area
      13. Madison County Indianapolis Area
      14. Marion County Indianapolis Area
      15. Morgan County Indianapolis Area
      16. Shelby County Indianapolis Area
      17. Jackson County Jackson Co., IN Area
      18. LaPorte County LaPorte, IN Area
      19. Clark County Louisville, KY-IN Area
      20. Floyd County Louisville, KY-IN Area
      21. Delaware County Muncie, IN Area
      22. Elkhart County South Bend/Elkhart, IN Area
      23. St. Joseph County South Bend/Elkhart, IN Area
      24. Vigo County Terre Haute, IN Area

CAIR is Smart for Indiana's Economy

• CAIR helps maintain coal as a viable fuel/energy source, keeping jobs in Indiana.

• Regional electricity prices are not significantly impacted by CAIR.

Notes:
1) Partial counties are identified by (P) following the county name.
2) Projections concerning future levels of air pollution in specific geographic locations were estimated using the best scientific models available. They are estimations, however, and should be characterized as such in any description. Actual results may vary significantly if any of the factors that influence air quality differ from the assumed values used in the projections shown here.
3) Small emission increases can occur in a state under CAIR where shifts in power generation occur, but overall improvements occur throughout the CAIR region. The Final CAIR includes a compliance supplement pool of NO_x allowances (roughly 200,000 allowances) for the annual program, which could lead to slightly higher annual NO_x emissions than are stated here.
4) The data presented here is based on recently completed, revised Integrated Planning Modeling (IPM), reflecting CAIR as finalized. This recent data may differ slightly from modeling results in the Final CAIR Federal Register Notice and Regulatory Impact Analysis (RIA) which were based on modeling that was completed before EPA had determined the final scope of CAIR. The primary difference in the earlier modeling included AR, DE, and NJ in the annual SO₂/NO_x requirements, and did not include an ozone season cap on any states.
5) Emissions reductions take into account state and federal pollution control programs in place when EPA last updated its models in mid-2004. Reductions from more recent state programs or settlement actions are not reflected in these tables.
6) Retail electricity prices are by North American Electric Reliability Corporation (NERC) region.
