  2. Five Regions Analyzed

  3. Condensed Emission Categories • Coal-based Electric Generating Units (EGUs) • Highway vehicles • Off-highway vehicles • Industrial fuel combustion & processes • All other

  4. Total U.S. NOx Emissions(In millions of tons/yr.)

  5. Share of U.S. NOx Emissions by Source Category, 1999-2010

  6. Percent Change in U.S. NOx Emissions,1999-2010

  7. Percent Change in Regional Coal-Based EGU NOx Emissions,1999-2010 Note: NE EGUs were subject to the OTC NOx MOU requiring 55%/65% NOx reductions from 1990 levels in 1999.

  8. Total U.S. SO2 Emissions(In millions of tons/yr.)

  9. Percent Change in U.S. SO2 Emissions,1999-2010
