  1. Impacts ofthe 2008 Ozone Standard: a State PerspectiveAugust 6, 2008Elliott Bickerstaff,Mississippi DEQ

  2. Potential Non-Attainment Areas Monitored Counties > 75 ppb MSA’s of Monitored Counties >75 ppb are in gray

  3. Bolivar County • Population – 38379 • Total Annual Nox Emissions – 5750 tons • Total Annual VOC Emissions – 5562 tons • Rural farm country • No adjacent large cities or industry • Population declining

  4. DeSoto County • Population – 138958 • Total annual NOx emissions – 8183 tons • Total annual VOC emissions – 8498 tons • Suburban and rural • Part of the Memphis MSA

  5. Lauderdale County • Population – 77261 • Total Annual Nox Emissions – 5024 tons • Total Annual VOC Emissions – 7302 tons • Generally rural • No adjacent large cities or industries • Population declining

  6. Harrison County • Population – 194226 • Total Annual Nox Emissions – 22,604 tons • Total Annual VOC Emissions – 17,159 tons • Urban south of I-10, more rural north • More industrially dense than most on MS • MSA includes Hancock and Stone counties

  7. Jackson County • Population – 137,200 • Total Annual Nox Emissions – 33,712 tons • Total Annual VOC Emissions – 33, 102 tons • Urban south of I-10, more rural north • More industrially dense than most on MS • MSA includes George County

  8. Timeline for NAAQS Revision

  9. State Designation Recommendations • Due March 2009 • Includes counties with non-attaining monitors • Can also include surrounding counties that contribute • All counties in the MSA with a violating county will need to be evaluated

  10. Monitored Counties > 75 ppb MSA’s of Monitored Counties >75 ppb are in gray

  11. Final Designations • March 2010 • Nonattainment NSR applies immediately • Transportation conformity applies in one year • State Implementation Plans due in three years (2013)

  12. SIPs • Emission Inventories which include emissions and transportation budgets • Modeling supporting future attainment • Emissions reductions • Reasonably Available Control Technology and Measures (RACT and RACM)

  13. Early Action Compacts(If Allowed) • Due prior to final designation are made (March 2010) • Must show compliance with the standard by the date SIPs would ordinarily be due (2013) • Would need to include many of the same components as the SIP • If successful gives a deferred status

  14. Challenges • General perception is that there isn’t an air quality problem • In most cases, local controls will have limited impacts • Potential economic impacts on declining areas • Timing

  15. In Closing • National and regional control measures such as CAIR and the mobile source standards are helpful in meeting this and future NAAQS Standards • Would like to see a mechanism, such as the early action compact, to provide a deferred status for marginal areas
