3. RDS Staffing Updates - 2013 *Detail to RDS #Military leave until March 2014; Michele Notarianni assuming role as FL & SC SIP Contact in the interim.

4. NAAQS and Regional Haze Updates

5. Status for Region 4 1997 8-Hour Ozone Areas Only two remaining nonattainment areas in Region 4 (Atlanta & North Carolina portion of Charlotte). Atlanta & North Carolina portion of Charlotte proposed for redesignation. Critical for actions was resolution of reasonably available control technology requirements, & approval of baseline emissions inventory & emissions statement SIPs.

6. 2008 8-Hour Ozone NAAQS Implementation Final ozone implementation rule expected Spring 2014. Emissions inventory & emission statement submissions due 2 years after designations. - clean data determination does not relieve these requirements. - areas cannot be redesignated without these requirements being met.

7. Status for Region 4 1997 Annual PM2.5 Areas All areas appear to be attaining the NAAQS. Five of the thirteen areas redesignated to attainment. Good monitoring data quality & resolution of any data issues critical for actions. Resolution of issues that arouse from litigation for the PM2.5 implementation rule was necessary also to move actions forward.

8. Status for Region 4 2008 Lead NAAQS Areas Three areas designated nonattainment & one area designated unclassifiable. All required submissions provided by Region 4 states. TN only required to provide emissions inventory submission because Bristol attaining & EPA completed clean data determination for the Area. AL & FL required to provide attainment demonstration submission which included emissions inventories, RACT, RACM & RFP in addition to attainment modeling.

9. 2010 Sulfur Dioxide Nonattainment Designations Nonattainment designations completed August 5, 2013 – effective October 4, 2013. Five areas in Region 4 as part of the 29 nonattainment areas designated nationally. Attainment SIPs due August 6, 2015. Attainment dates as expeditiously as practicable but no later than October 4, 2018.

10. Status of Region 4 Actions – Initial Regional Haze SIPs This… • Limited approval/limited approval completed for AL, GA, KY, MS, NC, SC & TN. • Full approval completed for FL – source by source BART & RP conducted (no reliance on CAIR or CSAPR). • Outstanding FIP clocks going for AL, NC & MS. Or This…

11. SIP Planning

12. SIP Processing in Region 4 • In FY13, processed 68 actions –52 (47 processed & 5 withdrawn) were backlogged (accounts for 17 consent decree deadlines met). • Enhanced communications for issue resolution • Region 4 has active role on national workgroups to stay informed of emerging issues. • Conscious effort to alert states & regional management as soon as issues emerge in attempt to quickly resolve issues. • Using quarterly & monthly calls to keep states informed.

13. FY 2014 Priorities

14. Challenges for FY 2014 • Balancing priorities with tighter EPA resources & catching up from impacts of the shutdown. • Meeting CD & statutory SIP processing deadlines • Designations • State/local priorities • Managing impacts of litigation & petitions on upcoming actions • Tools for communication • SIP tracking log • Early communications on priority SIPs (predrafts still welcomed!) • Will be important for states to continue to communicate priorities to state contact or RDS chief on monthly calls.

15. What’s on the Horizon?

16. Anticipated NAAQSImplementation Milestones (updated October 2013) Section 110 plans will be needed for multiple NAAQS in coming years. * Only considers dates for nonattainment areas; does not include dates for other areas.
