  1. NAAQS Status in GA & PSD Inventory UpdateJames W. BoylanGeorgia EPD – Air Protection BranchManager, Planning & Support ProgramAWMA Regulatory Update ConferenceMarch 29, 2016 – Atlanta, GA

  2. Background • Ozone • Formed in the atmosphere (NOx + VOC + sunlight) • Regional pollutant • Respiratory health effects • Particulate Matter (PM2.5) • Formed in the atmosphere & directly emitted • Local and regional pollutant • Cardiovascular health effects • Sulfur Dioxide (SO2) • Directly emitted • Local pollutant • Respiratory health effects 2

  3. Particulate MatterNAAQS 3

  4. Particulate Matter NAAQS • Particulate Matter (PM2.5) –Annual • Annual arithmetic mean, averaged over 3 years. • 1997 NAAQS – 15.0 mg/m3 • 2012 NAAQS – 12.0 mg/m3 • Particulate Matter (PM2.5) – Daily • 98th percentile of 24-hour daily average, averaged over 3 years. • 2006 NAAQS – 35.0 mg/m3 4

  5. Annual PM2.5 Design Value Trends 5

  6. 1997 Annual PM2.5(15.0 mg/m3) Atlanta Area • 2008-2010 • Clean PM2.5 data • August 30, 2012 • EPD submitted Maintenance Plan to EPA • February 24, 2016 • Redesignation to attainment!! (Prior to February 24, 2016) 6

  7. 2012 Annual PM2.5 (12.0 mg/m3) • 2011-2013 data • White counties attainment in 2014 • 2012-2014 data • Orangecounties attainment in 2015 • 2013-2015 data • Redcounties attainment in Spring 2016??? 7

  8. OzoneNAAQS 8

  9. Ozone NAAQS • Annual fourth-highest daily maximum 8-hour concentration, averaged over 3 years. • 2008 NAAQS – 75 ppb • 2015 NAAQS – 70 ppb • Currently, Atlanta (15 counties) is designated nonattainment for the 2008 ozone NAAQS. 9

  10. Ozone Design Value Trends 10

  11. 2008 Ozone NAAQS (75 ppb) Atlanta Area • 2012-2014 data • 77 ppb (above 75 ppb) • August 27, 2015 • Proposed “Marginal” to “Moderate” by EPA • 2013-2015 data • 73 ppb (below 75 ppb) • Maintenance Plan under development • Redesignation to attainment in 2016? 11

  12. 2015 Ozone NAAQS (70 ppb) • October 1, 2015 • NAAQS = 70 ppb • October 1, 2016 • EPD designation recommendations • 2013-2015 data • October 1, 2017 • EPA designations • 2014-2016 data • Atlanta would likely be “Marginal” • No additional emission controls required 12

  13. Sulfur DioxideNAAQS 13

  14. Sulfur Dioxide NAAQS 75 ppb, 99th percentile of 1-hour daily maximum concentrations, averaged over 3 years. 14

  15. SO2 Data Requirements Rule • SO2 NAAQS Data Requirements Rule (DRR) • Signed on August 10, 2015. • Published on August 21, 2015 (80 FR 51052) • The DRR was developed to address the need for additional air quality data to be used for implementing the 2010 1‐hour SO2 NAAQS. • The existing SO2 monitoring network characterizes localized SO2 source impacts in a limited set of areas. • The DRR directs state and tribal air agencies to characterize current air quality in areas with large SO2 sources (2,000 TYP or greater). • Facility can take permit limit below 2,000 TPY to be exempt. 15

  16. SO2 Designations • Round 1 – Violating Monitors • October 4, 2013 - EPA designated 29 areas nonattainment in 16 states based on monitored violations • April 4, 2015 - Attainment SIPs due • October, 2018 - Attainment date • Round 2 – Sierra Club Consent Decree • September 18, 2015 - State designation recommendations due to EPA • July 2, 2016 - EPA makes designations • Round 3 – Modeling Approach • January 15, 2016 - List of sources exceeding threshold due to EPA • July 1, 2016 - Modeling protocols due to EPA • January 13, 2017 - Modeling analysis due to EPA • December 31, 2017 - EPA makes designations based on modeling • Round 4 – Monitoring Approach • January 15, 2016 - List of sources exceeding threshold due to EPA • July 1, 2016 - States submit monitoring details to EPA as part of their annual monitoring network plan • January 1, 2017 - New monitors operational • December 31, 2020 - EPA makes designations based on 2017-2019 monitoring data 16

  17. Sierra Club Consent Decree • Round 2 of designations… • An earlier round of designations would be completed no later than 16 months from the Court’s entry of the consent decree (March 2, 2015) • September 18, 2015 -State recommendations due to EPA • July 2, 2016 - EPA makes designations • Consent decree applies to: • Coal-fired power plants that in 2012 emitted more than: • 16,000 tons of SO2, or • 2,600 tons of SO2 and had an emission rate of at least 0.45 lbs SO2/MMBtu • Georgia Power Plant Scherer • Areas that have newly monitored violations of the 1-hour SO2 NAAQS • Based on air quality modeling in the three (3) full calendar years preceding the Court deadline • One monitor in Savannah 17

  18. Consent Decree Recommendations • Plant Scherer in Monroe County • EPD recommended attainment for Monroe, Bibb, Jones, Jasper, Butts, Lamar, Upson, and Crawford. • EPA’s 120-day letter recommends Monroe, Jones, Jasper, Butts, Lamar, Upson, and Crawford (not Bibb). • Violating monitor in Savannah • Lathrop & Augusta SO2 monitor (13-051-1002) • 2012-2014 design value = 78 ppb • EPD recommended that the land including the IP-Savannah main mill and the area surrounding the violating SO2 monitor (Jasper Spring Park) be designated nonattainment. • In early 2016, GA EPD early certify the SO2 data at this monitor. • 2013-2015 design value = 70 ppb • This area has been removed from the Consent Decree schedule (Round 2) and will be designated based on modeling (Round 3). 18

  19. Large SO2 Sources in Georgia *International Paper - Rome plans to use the monitoring approach. Must relocate current SO2 monitor to new location. **The three facilities in yellow highlight were not included on Georgia’s SO2 DRR source list, but were added by EPA. 19

  20. PSD Off-Site Emissions Inventory 20

  21. PSD Emissions Inventory • GA EPD is creating a statewide emission inventory for the PSD air impact analysis • NAAQS & Increment • PM10, PM2.5, NOx, SO2, and CO • Follow 40 CFR 51 Appendix W • Contractor support from AMEC • GA EPD will maintain future updates to the emission inventory through the permit application process. • All emissions will be available on-line 21

  22. Project Deliverables • Emission Inventory Data and Notebook • 792 SM and 389 Title V sources • Emissions Inventory Web Application • Select location and radius • AERMOD ready file • Excel file with Q/d calculations • AMEC contract ended January 31, 2016 • GA EPD is backfilling emission inventory data for the past 18 months • GA EPD is filling in missing stack parameters • Plan to release to the public in mid-2016 • Facilities can submit updates to EPD 22
