Michigan’s Emissions Under CAIR

  • By 2015, emissions from Michigan sources will increase less than they would without CAIR - 34,000 tons, or just under 10 percent, as opposed to 47,000 tons.
SO2 Emissions (thousand tons) 2003 2010 2015
Michigan SO2 emissions without CAIR 351 387 398
Michigan SO2 emissions with CAIR N/A 381 385
  • By 2015, CAIR will help Michigan sources reduce emissions of nitrogen oxides (NOx) by 34,000 tons or 29 percent.
NOx Emissions (thousand tons) 2003 2009 2015
Michigan NOx emissions without CAIR 119 117 120
Michigan NOx emissions with CAIR N/A 88 85

CAIR Helps Michigan and its Neighbors

  • Because air emissions travel across state boundaries, reducing the emissions from sources in Michigan also will reduce fine particle pollution and ground-level ozone pollution in other areas of the country.
  • Michigan sources significantly contribute to fine particle pollution in 8 other states:
        Pennsylvania, Ohio, Illinois, Kentucky, West Virginia, Indiana, Delaware & New Jersey
  • Michigan sources also contribute significantly to ground-level ozone pollution in 6 other states:
        Maryland, New Jersey, Pennsylvania, New York, Delaware & Ohio
  • Michigan’s fine particle air quality will improve because of reductions of SO2 and NOx in:
        Illinois, Indiana, Ohio, Pennsylvania & Wisconsin
  • Michigan’s ground-level ozone air quality will improve because of reductions of NOx in:
        Illinois, Indiana, Iowa, Wisconsin, Kentucky & Ohio

CAIR Makes Michigan’s Air Cleaner

  • CAIR helps Michigan meet and maintain the National Ambient Air Quality Standards (NAAQS) for ground-level ozone and fine particle pollution.
  • SO2 and NOx contribute to the formation of fine particles (PM), and NOx 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

    • At the end of 2004, 7 Michigan counties were designated nonattainment for EPA’s health-based standards for fine particle pollution.
    • CAIR will help these counties come closer to attaining the PM standards:
          1. Livingston County Detroit-Ann Arbor, MI Area
          2. Macomb County Detroit-Ann Arbor, MI Area
          3. Monroe County Detroit-Ann Arbor, MI Area
          4. Oakland County Detroit-Ann Arbor, MI Area
          5. St. Clair County Detroit-Ann Arbor, MI Area
          6. Washtenaw County Detroit-Ann Arbor, MI Area
          7. Wayne County Detroit-Ann Arbor, MI Area

    Ground-level Ozone

    • At the end of 2004, 25 Michigan counties were designated nonattainment for EPA’s health-based standards for ground-level ozone pollution.
    • Existing Clean Air Act Programs will bring 17 of these counties into attainment by 2010:
          1. Allegan County Allegan Co., MI Area
          2. Berrien County Benton Harbor, MI Area
          3. Benzie County Benzie Co., MI Area
          4. Cass County Cass Co., MI Area
          5. Genesee County Flint, MI Area
          6. Lapeer County Flint, MI Area
          7. Kent County Grand Rapids, MI Area
          8. Ottawa County Grand Rapids, MI Area
          9. Huron County Huron Co., MI Area
          10. Calhoun County Kalamazoo-Battle Creek-MI Area
          11. Kalamazoo County Kalamazoo-Battle Creek-MI Area
          12. Van Buren County Kalamazoo-Battle Creek-MI Area
          13. Clinton County Lansing-East Lansing-MI Area
          14. Eaton County Lansing-East Lansing-MI Area
          15. Ingham County Lansing-East Lansing-MI Area
          16. Mason County Mason Co., MI Area
          17. Muskegon County Muskegon Co. MI Area
    • CAIR will help bring the other 8 counties into attainment by 2015:
          1. Lenawee County Detroit-Ann Arbor, MI Area
          2. Livingston County Detroit-Ann Arbor, MI Area
          3. Macomb County Detroit-Ann Arbor, MI Area
          4. Monroe County Detroit-Ann Arbor, MI Area
          5. Oakland County Detroit-Ann Arbor, MI Area
          6. St. Clair County Detroit-Ann Arbor, MI Area
          7. Washtenaw County Detroit-Ann Arbor, MI Area
          8. Wayne County Detroit-Ann Arbor, MI Area

CAIR is Smart for Michigan’s Economy

  • CAIR helps maintain coal as a viable fuel/energy source.
  • Regional electricity prices are not significantly impacted by CAIR.
Average Retail Electricity Prices (AREP) in 1999 dollars 2000 2010 2015
Michigan’s AREP without CAIR (mills/kWh*) 57.4 51.7 55.2
Michigan’s AREP with CAIR (mills/kWh*) N/A 53.7 58.6
    *mill = 1/10 of a cent


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 NOx allowances (roughly 200,000 allowances) for the annual program, which could lead to slightly higher annual NOx 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/NOx 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.
