RE: Maintenance Plan and Redesignation Request forthe Rome, Georgia (Floyd County), Annual PM 2.5 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 1997Annual PM2.5 National Ambient Air Quality Standard (NAAQS) in the Rome area. This submittal also serves as a request that the Rome NonattainmentArea be redesignated as an area attaining the 1997 Annual PM2.5 NAAQS. On April 5, 2011, EPA published a final rule determining that the Rome Area had attained the 1997 fine particulate matterstandards. On September 8, 2011, EPA published a final rule making a determination thatthe Rome 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 Rome Area in a letterto EPA dated June 29, 2011. The emissions inventory submitted with the October20, 2009, SIP revision to comply with the Clean AirAct requirements of§172 for nonattainment areas was not affected by the June 20, 2011, request. The public notice forthe proposed SIP revision was advertised using the EPD Air 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 Rome Area. Rule (ooo) was removed because the version currently in the approved SIP is identical to the requirements of national rule and the most recent rule revision has not been approved by EPA. As required by the federal SIP-processing regulations, we have enclosed certifications that the required public notices were provided and that a public hearing was held. We have also enclosed the administrative and technical support checklists to satisfythe SIP submittal completeness criteria. This submittal includes one paper copy ofeach of the relevant documents and a compact diskwith an electronicversion ofthe documents. The electronic version is an exact duplicate ofthe paper copy.Ms. Gwendolyn Keyes Fleming Page 2
