Ozone Status Update

• Atlanta will be bumped up from “Marginal” to “Moderate” sometime this year since 3-year design value (DV) for 2012-2014 is above 75 ppb.• Must submit an attainment SIP within 1-year

after bump-up • What will happen in 2015?

Implementing the 1-Hour SO2 NAAQS

9

• Round 1• October 4, 2013: 29 areas designated nonattainment (none in Georgia)

• Round 2• January 15, 2016: States submit list of SO2 sources to EPA and indicate modeling

or monitoring approach• January 13, 2017: Modeling analyses due to EPA• December, 2017: EPA designations based on modeling analysis and existing

monitors

• Round 3• January 1, 2017: New monitors operational• 2020: EPA makes designations (2017-2019 data)

• Consent Decree• Early rounds of designations (July 2, 2016) for newly monitored violations of the

NAAQS and large coal-fired EGUs• Recommendations due to EPA in September 2015

The Air Quality in Georgia Is Expected to Continue to Improve

How Will Georgia EPD Develop a State Plan to Implement the CPP?

• Work closely with Georgia Environmental Finance Authority and the Georgia Public Service Commission to share information regarding various aspects of the rule

• Engage utilities, non-governmental organizations (NGOs) and other stakeholders in discussions regarding plan approaches

• Meet with US EPA to discuss Georgia-specific concerns• Hold public stakeholder meetings. The next stakeholder

meeting is scheduled for October 8, 2015• Share information with other southeastern states • Litigation over various aspects of the CPP is widely expected.

EPD will continue to track legal developments as they may impact the ultimate requirements of the CPP.
