RE: Amendments to Georgia's State Implementation Plan (SIP) pertaining to: 

Revisions to Georgia Rule (mmm), NOx Emissions from Stationary Gas 

Turbines and Stationary Engines, 

Removal of Georgia Rule (aaa), Consumer and Commercial Products, 

Removal of Georgia Rule (bbb), Gasoline Marketing Rule 

Dear Ms. Toney: 

With this letter, the Georgia Environmental Protection Division (EPD) is submitting for approval 

and incorporation to Georgia's State Implementation Plan (SIP) revisions to Georgia Rule 391-

3-1-.02(2)(mmm), NOx Emissions from Stationary Gas Turbines and Stationary Engines used 

to Generate Electricity, and amendments to remove Georgia Rule 391-3-1-.02(2)(aaa), 

Consumer and Commercial Products, and Georgia Rule 391-3-1-.02(2)(bbb), Gasoline 

Marketing, from the Georgia SIP. Georgia EPD demonstrates in this SIP revision that these 

revisions to Georgia's SIP are consistent with section 110 (I) of the Clean Air Act and will not 

interfere with the attainment of the National Ambient Air Quality Standards or with reasonable 

further progress toward that attainment. 

This SIP submittal focuses on ozone and PM2.5, the two national ambient air quality standards 

that could be impacted by the removal of these rules. While ozone is the mostly likely standard 

to be affected, PM2.5 has also been evaluated. Georgia is currently in attainment for S02, 

N02, CO, and lead; and these revisions to the SIP will not increase emissions of these 

pollutants or their related precursors. There is no concern these SIP revisions will interfere 

with compliance with these NAAQS in these attainment areas. Specifically, in the case of S02, 

EPA has not designated any counties in the metro Atlanta area as nonattainment and this SIP 

revision will not increase emissions of S02 or its precursors such that the area would violate 

the NAAQS. 

As required by the federal SIP-processing regulations, we have enclosed certifications that the 

required public notices were provided and that public hearings were held. EPA submitted a 

letter with one written comment on the proposed amendments indicating that subsequent 

guidance may need to be provided in the future on the contingency measures documented in 

this SIP revisions due to the newly effective implementation of the Cross State Air Pollution 

Rule (CSAPR). No verbal public comments were received at the public hearing. Georgia EPD 

has, however, made one change in the draft SIP revision. Sections 7.1.2 and 7.1.3 were 

changed to clarify the actions necessary if contingency measures are to be triggered.

We have also enclosed the administrative materials and technical support to satisfy the SIP 

submittal completeness criteria checklist. This submittal includes one paper copy of the 

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

electronic version is an exact duplicate of the paper copy with the following exceptions. Per 

Attachment A of Janet McCabe's April 6, 2011, memo pertaining to consistency of SIP 

administrative requirements, the following portions of the submittal are provided in the 

. electronic copy only: 

• Appendix C-1: Atlanta Sensitivity Summary: Spreadsheet of Data for Sensitivity Analysis 

(one data file) 

• Appendix D: SEMAP Sensitivity Study Final Report (one .pdf file) 

• Appendix E: Diesel Retrofit Documentation (two data files) 

Paper copies of these large data files are not provided in order to relieve unnecessary paper 

burden. One copy of this submittal will be sent to the EPA Region 4 associates noted below. 

We look forward to your review and approval of these revisions. Should you or your staff have 

any questions, please feel free to contact James Boylan at (404) 363-7014. 

Sincerely,
