6. Environmental Protection Division Annual PM2.5 Standard Issues – All 4 Nonattainment Areas –NOx Insignificance Determination Approvability Issue –Data Completeness

7. Environmental Protection Division PM 2.5 – 2007-2009 Design Value (µg/m3) Highest Monitor in Area standard

8. Environmental Protection Division PM 2.5 Standard – Permit Modeling Issues Currently under PM10 Surrogate Policy Must Revise PSD Program to Incorporate PM2.5 by 5/16/2011 Significant Impact Levels (SILs), Significant Monitoring Concentration (SMC), and Increment Proposed but Not Final EPA has Proposed to End use of PM10 Surrogate Policy Prior to 5/16/2011 For Now, –Applicant Should Propose SIL –Use Nearest PM2.5 Monitor as Background Call EPD if you Fail

10. Ozone – 4 th Highest 8-Hour Value Highest Monitor in Area standard

11. Environmental Protection Division 2010 Ozone Critical Values Yellow = Augusta CBSA Blue = Columbus-Auburn- Opelika CSA Green = Atlanta CSA Purple = Chattanooga CSA

12. Environmental Protection Division 1997 Ozone Standard Atlanta Nonattainment Area Attainment SIP Submitted 10/21/2009 –Attainment Date (Moderate Nonattainment Area): June 15, 2010 (Based on 2007-2009 Data) 2007-2009 Design Value = 0.087 ppm All Atlanta NAA Monitors Below 0.084 ppm in 2009 EPD Submitted1-Year Extension of Attainment Date on 6/6/2010 Should Allow for Better Transition to 2010 Standard

13. Environmental Protection Division Lead Monitoring Data micrograms per cubic meter 3-month rolling average SiteOct-DecNov-JanDec- Feb Jan-Mar Cartersville (source- oriented site) --0.01 Columbus (source- oriented site) 0.03 0.02 Atlanta (NCore site) 0.00 Standard0.15

14. Environmental Protection Division New NO 2 Monitoring Requirements “Near Road” Monitors –Atlanta: 2 –Augusta: 1 Community-Wide Monitors –Atlanta Startup by January 1, 2013 –After Nonattainment Designations

15. Environmental Protection Division

16. Existing NO 2 Data 98 th percentile of daily maximum values 2007-2009 averages NOT “near road” monitors standard

17. Environmental Protection Division Revised NO 2 Standard – Permit Modeling Issues For any PSD Permit Issued On or After 4/12/2010 4/1/2010 Steve Page Memo: –New or modified major stationary sources of NOx must demonstrate that they will not cause or contribute to a violation of the revised NO2 standard. 6/28/2010 Anna Marie Wood Memo: –Interim 1-hr NO2 Significant Impact Level (SIL) for Implementing Federal PSD Program 4 parts per billion For Now, in Georgia –Modeling Protocols Approved Prior to 6/28/10 – Use SIL proposed in approved protocol, must include justification –Modeling Protocols Approved After 6/28/2010 – Use Interim SIL developed for Federal program

18. Environmental Protection Division Monitoring Requirements for New SO2 Standard CBSARequiredIn Operation Atlanta-Sandy Springs-Marietta 31 (plus one mothballed) Macon11 Savannah12 Augusta-Richmond County 10 Total64 (plus one mothballed)

19. Environmental Protection Division

20. Existing SO 2 Data 99 th percentile of daily maximum values 2007-2009 averages Notes: Ga Tech mothballed Columbus initial startup – 2/6/2008 standard

21. Environmental Protection Division 99 th percentile

22. Environmental Protection Division Revised SO 2 Standard – Permitting Issues Revised NAAQS Effective August 23, 2010 New or modified major stationary sources of SO 2 (e.g., large industry, power plants) –must demonstrate that they will not cause or contribute to a violation of the revised SO 2 standard –done through computer modeling (AERMOD) –Issues No Proposed 1-hour SIL Could be very difficult for a facility to pass 1-hour standard

23. Environmental Protection Division Recent Rule Changes January, 2009 –95% SO2 Reduction for all Coal-Fired Utility Boilers Equipped with Scrubbers * (90% for one small unit with older scrubber) – Companion to Georgia Multi-Pollutant Rule October, 2009 –Adopted Federal Area Source NESHAPs May, 2010 –Permit Fees Late Fee of 0.05% Per Day Starting 10/1/2010 Beginning with 2009 Fees, New Owner of Facility is Responsible for Past-Due Fees from Previous Owner *90% of capacity will have scrubbers

24. Environmental Protection Division Upcoming Rule Changes December, 2010 –PSD for PM2.5 –Greenhouse Gas Tailoring Rule 2011 –Revised VOC Rules to Conform with Recently Issued Control Technology Guidelines (CTGs) –SIL, SMC, Increment for PM2.5 –Nonattainment NSR for PM2.5 –NOx Limits for Coal-Fired Utility Boilers in North Georgia - Companion to Georgia Multi-Pollutant Rule (maybe)
