  1. Alabama Air UpdateRon GoreADEMAugust, 2010

  2. Topics • “Re-Visit” and “Un-do” Everything • Tightening of Air Quality Standards • GHG’s • MACT’s • State Issues

  3. Nonattainment Formal designation by EPA that an area does not meet a standard or that it contributes to an area not meeting the standard. Note: By State and Federal law, EPA has total authority over the standards and for setting boundaries of non-attainment areas.

  4. Consequences of Nonattainment • Considered to have unhealthy air • Transportation planning must consider air quality impacts( mostly procedural) • Obstacles to growth of large new industries

  5. National Ambient Air Quality StandardsJune 2010

  6. Ozone • Status: EPA has proposed to tighten the NAAQS to within the range of 60-70ppb and a secondary standard within the range of 7-15ppm-hours. Final standards to be issued by August 31,2010. • Implications for Alabama: 3-9 possible new nonattainment areas and up to 4 new monitors.

  7. Counties Over an 8-Hour Ozone NAAQS of 65 ppb 2007-2009 Lauderdale Limestone Jackson Madison Colbert Lawrence DeKalb Franklin Morgan Marshall Cherokee Cullman Marion Winston Etowah Blount Walker Calhoun Lamar Fayette St. Clair Cleburne Jefferson Talladega Tuscaloosa Shelby Clay Pickens Randolph Bibb Coosa Greene Chambers Tallapoosa Chilton Hale Perry Lee Elmore Sumter Autauga Macon Dallas Montgomery Russell Marengo Lowndes Bullock Choctaw Wilcox Barbour Butler Pike Clarke Crenshaw Monroe Henry Dale Washington Conecuh Coffee Covington Houston Escambia Geneva Mobile O3 < 65 ppb O3 > 65 ppb Baldwin

  8. Worst Case Nonattainment Areas based on an 8-Hour Ozone NAAQS of 65 ppb 2007-2009 Lauderdale Limestone Jackson Madison Colbert Lawrence DeKalb Franklin Morgan Marshall Cherokee Cullman Marion Winston Etowah Blount Walker Calhoun Lamar Fayette St. Clair Cleburne Jefferson Talladega Tuscaloosa Shelby Clay Pickens Randolph Bibb Coosa Greene Chambers Tallapoosa Chilton Hale Perry Lee Elmore Sumter Autauga Macon Dallas Montgomery Russell Marengo Lowndes Bullock Choctaw Wilcox Barbour Butler Pike Clarke Crenshaw Monroe Henry Dale Washington Conecuh Coffee Covington Houston Escambia Geneva Mobile O3 < 65 ppb O3 > 65 ppb Baldwin

  9. Previous Ozone NAAQS

  10. Particulate Matter (PM2.5) • Status: EPA may lower the annual standard to 10-13µg/m3 and lower the 24-hour standard to 25-35µg/m3 . Proposal expected around November 2010. • Implications for Alabama: Approximately 3-7 new nonattainment areas.

  11. Previous PM2.5 Standards

  12. SulfurDioxide • Status: On June 2, 2010, EPA tightened the primary NAAQS to 75 ppb measured over 1-hour. EPA revoked the 24-hour NAAQS (140 ppb) and the annual NAAQS (30 ppb). • Implications for Alabama: Some new nonattainment areas and 4 to 6 new monitors. • ADEM has performed modeling of two SO2 and NO2 sources. (A power plant and a pipeline compressor station) The results of this modeling indicate that these type sources will have difficulty complying with the revised standards.

  13. Nitrogen Dioxide • Status: 1-hour standard was finalized on February 9, 2010. • Implications for Alabama: At least 1 new nonattainment area and up to 2 new monitors. • ADEM has performed modeling of two SO2 and NO2 sources. (A power plant and a pipeline compressor station) The results of this modeling indicate that these type sources will have difficulty complying with the revised standards.

  14. Timelines for New Standards • Ozone-Designation process could be complete by late 2011 • PM 2.5- Late 2012 at earliest • SO2 and NOx- Late 2015 or later

  15. Lead • Status: EPA has proposed to change the ambient monitoring threshold to 0.50 tons per year. • Implications for Alabama: At least 1 new nonattainment area and up to 10 new monitors.

  16. Carbon Monoxide • Status: EPA may tighten in 3 to 5 years. • Implications for Alabama: None

  17. Particulate Matter (PM10) Status: No changes expected in the near future Implications for Alabama: None

  18. GHG’s • States have no role in reporting rule • The GHG permitting rules, to a great extent, involve useless red tape, EXCEPT

  19. Exception • EPA is insisting that BACT includes such things as: • Alternate fuels • Plant-wide energy audits • Alternate processes

  20. State Rule for GHG’s • ADEM hopes to present rule change to the Environmental Management Commission for adoption in December • Rules would raise PSD thresholds to EPA’s levels • Asking EPA to parallel process a SIP change

  21. MACT’s • Start-ups, Shutdown, and Malfunction • Franken-MACT

  22. State Issues • Title V fee $35/ton for next few years • No fees for GHG’s • Will do rulemaking for Title V and GHG’s later • Personnel change
