RE: Maintenance Plan and Redesignation Request forthe Macon, Georgia, Annual PM2.5 NonattainmentArea Dear Ms. Fleming: With this letter, the Georgia Environmental Protection Division (EPD) is submitting for approval and incorporation the proposed revisions to Georgia's State Implementation Plan (SIP) to include a plan, consistent with §175A ofthe Clean AirAct, to provide for maintenance ofthe 1997 Annual PM25 National Ambient AirQuality Standard (NAAQS) in the Macon area. This submittal also serves as a request that the Macon NonattainmentArea be redesignated as an area attaining the 1997Annual PM2.5 NAAQS. On June 2, 2011, EPA published a final rule determining that the Macon Area had attained the 1997 fine particulate matter standards. On September8, 2011, EPA published afinal rule making a determination that the Macon Area had attained the 1997 annual PM2.5 standard prior to the April 5, 2010, attainment date. Georgia EPD withdrew its previous submittal of nonattainment planning documents forthe Macon Area in a letterto EPA dated June 29, 2011. The emissions inventory submitted with the June 12, 2009, SIP revision to comply with the Clean AirAct requirements of§172 for nonattainment areas was not affected by the June 29, 2011, request. The public notice forthe proposed SIP revision was advertised using the EPDAir Protection Branch listserv mailing list for public notices. No comments were received. However, Georgia's Heavy Duty Diesel Engines rule [391-3-1-.02(2)(ooo)] was removed from Section 2.3.2 ofthe prehearing SIP, which is the discussion ofstate measures that have contributed to permanent and enforceable emissions reductions in the Macon Area. Rule (ooo) was removed because the version currently approved in Georgia's SIP is identical to the requirements ofthe national rule the most recent rule revision has not been approved by EPA. As required bythe federal SIP-processing regulations, we have enclosed certifications that the required public notices were provided and that a public hearingwas held. We have also enclosed the administrative and technical support checklists to satisfythe SIP submittal completeness criteria. This submittal includes one paper copy ofeach ofthe relevant documents and a compact diskwith an electronic version ofthe documents. The electronic version is an exact duplicate ofthe paper copy.Ms. Gwendolyn Keyes Fleming Page 2
