  2. Federal Air Quality Rules Affecting Mississippi • CAIR • CAMR • Regional Haze • Ozone • PM2.5

  3. CAIR • Federal Regulations adopted by Mississippi and effective on November 16, 2006 • EPA published Mississippi SIP modification proposal in the Federal Register on July 12, 2007 • Applications are due for NOx and SO2 by July 1, 2008. • Allocations have been submitted.

  4. CAMR • Applications are due by July 1, 2008 • Allocations were submitted by October 31, 2006 • State regulations were amended November 16, 2006, in order to adopt the federal regulations.

  5. Regional Haze • Modeling shows that Mississippi sources do not significantly affect the Sipsey Wilderness Area in Alabama and the Caney Creek Wilderness Area in Arkansas. • Mississippi is currently working strategic long range planning for impacts on the Breton Island Wilderness Area in Louisiana. • We have consulted with Federal Land Managers and Louisiana DEQ. • SIPs are due by December 17, 2007

  6. 8- Hour Ozone • All ozone monitoring sites in Mississippi continued to attain the current ozone standard of 0.08 ppm during 2004 - 2006. • However, ozone design values for DeSoto County and Harrison County are trending higher and are close to the standard. • The MDEQ ozone forecasting program continues to be implemented in DeSoto County and on the Mississippi Gulf Coast. • DeSoto County is forming an ozone action group similar to the one that has been formed on the Mississippi Gulf Coast. • MDEQ is focusing on outreach and public awareness in DeSoto County.

  7. PM2.5 • All PM2.5 monitoring sites in Mississippi continued to attain the PM2.5 annual standard of 15 µg/m3 for 2004 - 2006. • All PM2.5 monitoring sites attained the new PM2.5 24-hour standard of 35 µg/m3 for 2004 – 2006. • Therefore, the governor will propose no nonattainment areas in the state for the 24-hour standard.

  8. Other Air Quality Issues • Depending upon the final version of the recently proposed 8-hour ozone standard, Mississippi may have areas that are designated as not attaining the standard. • The MDEQ air monitoring site in Hancock County should be operating again in January 2008. • The MDEQ has a new web site with further details about the Air Division and its programs at: http://www.deq.state.ms.us
