RE: Maintenance Plan and Redesignation Request for the Macon, Georgia, Annual PM2.5 

Nonattainment Area 

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 of the Clean Air Act, to provide for maintenance of the 

1997 Annual PM25 National Ambient Air Quality Standard (NAAQS) in the Macon area. This 

submittal also serves as a request that the Macon Nonattainment Area be redesignated as an 

area attaining the 1997 Annual 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 September 8, 2011, EPA published a final 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 for the Macon Area in a letter to EPA dated June 29, 2011. 

The emissions inventory submitted with the June 12, 2009, SIP revision to comply with the 

Clean Air Act requirements of §172 for nonattainment areas was not affected by the June 29, 

2011, request. 

The public notice for the 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 of the 

prehearing SIP, which is the discussion of state 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 of the national 

rule 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 satisfy the SIP submittal 

completeness criteria. This submittal includes one paper copy of each of the relevant 

documents and a compact disk with an electronic version of the documents. The electronic 

version is an exact duplicate of the paper copy.
