ACTION: Final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is approving the State of 

Georgia’s February 5, 2015, State 

Implementation Plan (SIP) revision, 

submitted through the Georgia 

Environmental Protection Division (GA 

EPD), to modify the SIP by removing 

Georgia’s Gasoline Marketing Rule and 

Consumer and Commercial Products 

Rule, revising the Nitrogen Oxide (NOX) 

Emissions from Stationary Gas Turbines 

and Stationary Engines Rule, and 

adding measures to offset the emissions 

increases expected from the changes to 

these rules. This modification to the SIP 

will affect, in varying ways, the 45 

counties in and around the Atlanta, 

Georgia, metropolitan area covered by 

the Georgia Gasoline Marketing Rule 

(hereinafter referred to as the ‘‘Georgia 

Fuel Area’’). Additionally, EPA is also 

approving structural changes to the NOX

Emissions from Stationary Gas Turbines 

and Stationary Engines Rule included in 

a SIP revision submitted by GA EPD on 

September 26, 2006. EPA has 

determined that the portion of Georgia’s 

September 26, 2006, SIP revision 

addressing changes to the NOX

Emissions from Stationary Gas Turbines 

and Stationary Engines Rule and the 

February 5, 2015, SIP revision meet the 

applicable provisions of the Clean Air 

Act (CAA or Act).

SUPPLEMENTARY INFORMATION: 

I. Background for Final Action 

On November 16, 1991, EPA 

designated and classified the following 

counties in Georgia, either in their 

entirety or portions thereof, as a serious 

ozone nonattainment area for the 1-hour 

ozone NAAQS (hereinafter referred to as 

the ‘‘Atlanta 1-Hour Ozone Area’’): 

Cherokee, Clayton, Cobb, Coweta, 

DeKalb, Douglas, Fayette, Forsyth, 

Fulton, Gwinnett, Henry, Paulding, and 

Rockdale. Among the requirements 

applicable to the nonattainment area for 

the 1-hour ozone NAAQS was the 

mstockstill on DSK4VPTVN1PROD with RULES

52628 Federal Register / Vol. 80, No. 169 / Tuesday, September 1, 2015 / Rules and Regulations 

1The Georgia Fuel Area consists of the following 

45 counties: Banks, Barrow, Bartow, Butts, Carroll, 

Chattooga, Cherokee, Clarke, Clayton, Cobb, 

Coweta, Dawson, DeKalb, Douglas, Fayette, Floyd, 

Forsyth, Fulton, Gordon, Gwinnett, Hall, Haralson, 

Heard, Henry, Jackson, Jasper, Jones, Lamar, 

Lumpkin, Madison, Meriwether, Monroe, Morgan, 

Newton, Oconee, Paulding, Pickens, Pike, Polk, 

Putnam, Rockdale, Spalding, Troup, Walton and 

Upson. This Area encompasses the 20-county 8- 

hour Atlanta ozone maintenance area for the 1997 

ozone NAAQS and the 15-county 8-hour Atlanta 

ozone nonattainment area for the 2008 ozone 

NAAQS. Georgia received a waiver under section 

211(c)(4)(C) of the CAA to adopt a state fuel 

program that is more stringent than that which was 

federally required for the Atlanta 1-Hour Ozone 

Area. The Georgia Fuel Rule requires the sale of low 

sulfur, 7.0 psi RVP gasoline in the Georgia Fuel 

Area. 

2The Consumer and Commercial Products Rule 

applies in the following 13 counties that make up 

the former Atlanta 1-hour ozone nonattainment 

area: Cherokee, Clayton, Cobb, Coweta, DeKalb, 

Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, 

Paulding, and Rockdale. 

3 Georgia Rule 391–3–1-.02(2)(mmm) only applies 

in the Georgia Fuel Area. 

requirement to meet certain volatility 

standards (known as Reid Vapor 

Pressure or RVP) for gasoline sold 

commercially. See 55 FR 23658 (June 

11, 1990). Subsequently, in order to 

comply with the 1-hour ozone NAAQS, 

Georgia opted to implement Georgia 

Rule 391–3–1-.02(2)(bbb), Gasoline 

Marketing (hereinafter referred to as the 

‘‘Georgia Fuel Rule’’), which requires 

the sale of low sulfur, 7.0 RVP gasoline 

in the 45-county Georgia Fuel Area 

during the high ozone season.1 EPA 

incorporated the Georgia Fuel Rule into 

the Georgia SIP on July 19, 2004. See 69 

FR 33862 (June 17, 2004). 

On February 5, 2015, GA EPD 

submitted a SIP revision to modify the 

SIP by removing Georgia Rule 391–3–1- 

.02(2)(aaa), Consumer and Commercial 

Products,2 and Georgia Rule 391–3–1- 

.02(2)(bbb), Gasoline Marketing, and 

revising Georgia Rule 391–3–1- 

.02(2)(mmm), NOx Emissions from 

Stationary Gas Turbines and Stationary 

Engines used to Generate Electricity.3

The SIP revision also includes measures 

to offset the emissions increases 

expected from the changes to these rules 

and a technical demonstration that these 

changes will not interfere with 

attainment or maintenance of any 

national ambient air quality standards 

(NAAQS or standard) or with any other 

applicable requirement of the CAA. 

Additionally, the State submitted a SIP 

revision on September 26, 2006, that 

contains structural changes to Georgia 

Rule 391–3–1-.02(2)(mmm). 

Georgia Rule 391–3–1-.02(2)(mmm) 

reduces emissions from stationary, peak 

performing engines that tend to operate 

during high electricity demand days in 

the 45-county Georgia Fuel Area. The 

State’s February 5, 2015, SIP revision 

modifies the rule to exempt stationary 

engines at data centers from the rule’s 

NOX emission limits provided that the 

engines operate for less than 500 hours 

per year and only for routine testing and 

maintenance, when electric power from 

the local utility is not available, or 

during internal system failures. The rule 

change also limits routine testing and 

maintenance of these engines during the 

high ozone season to the hours of 10 

p.m. to 4 a.m. to reduce the possibility 

of ozone formation due to these 

emissions. The September 26, 2006, SIP 

revision makes a structural change to 

the SIP-approved version of the 

regulation, pulling the emergency 

engine exemption into a new paragraph 

(Paragraph 7) and limits the exemption 

to the emission limits in Paragraph 1 of 

the rule. 

The February 5, 2015, SIP revision 

includes two offset measures—school 

bus replacements and rail locomotive 

conversions—to obtain the necessary 

emissions reductions to offset the rule 

changes identified in that submittal. The 

State’s school bus replacement program 

permanently replaced 60 older school 

buses in DeKalb, Fayette, Henry, and 

Madison Counties with the newer and 

cleaner 2015 model year buses by 

October 2014. The locomotive 

conversion program consists of two 

components: (1) The conversion of 28 

locomotives from Norfolk Southern 

Railway Company and CSX 

Transportation to EPA Tier 3 switch 

duty, Tier 3 Line-Haul, and Tier 2 

Switch emissions standards, and (2) the 

installation of an electric layover system 

at the Norfolk Southern Atlanta 

Terminal. The State demonstrated that 

the offset measures result in equivalent 

or greater emissions reductions that are 

permanent, enforceable, quantifiable, 

surplus, and contemporaneous. 

In addition, Georgia’s SIP revision 

includes a contingency offset measure 

in the event that the locomotive 

conversion program cannot be fully 

completed. The contingency measure 

would obtain NOX offsets from the 

permanent retirement of Unit 3 at 

Georgia Power’s Eugene A. Yates SteamElectric Generating Plant. Upon a 

determination that sufficient offsets will 

not be achieved within one year from 

the date of EPA’s final action on 

Georgia’s February 5, 2015, SIP 

submission, GA EPD will revise Georgia 

Rule 391–3–1-.02(12)(f), Clean Air 

Interstate Rule NOX Annual Trading 

Program, for the purposes of retiring or 

reducing the appropriate New Source 

Set Asides and submit that rule 

revision, along with the Title V permit 

condition that requires the shutdown of 

Unit 3, as a SIP revision. GA EPD will 

use the necessary substitute emissions 

reductions to replace any emissions 

shortfall in the event the locomotive 

conversions are not completed. EPA has 

determined that the State has 

successfully demonstrated that 660 tons 

of NOX offset is available through 

implementation of the contingency 

measure in the event the locomotive 

conversion program is not completed 

and that the measures will be 

permanent, enforceable, quantifiable, 

contemporaneous, surplus, and 

equivalent. 

In a notice of proposed rulemaking 

(NPR) published on June 26, 2015, EPA 

proposed to approve the February 5, 

2015, SIP revision and the portion of the 

September 26, 2006, submission that 

contains structural changes to Georgia 

Rule 391–3–1-.02(2)(mmm). See 80 FR 

36750. The details of Georgia’s 

submittals and the rationale for EPA’s 

action is explained in the NPR. 

EPA received one comment on the 

NPR. This comment, submitted by the 

Society of Independent Gasoline 

Marketers of America and provided in 

the docket for today’s final action, 

supports approval of the February 5, 

2015, SIP revision but expresses 

concern about the timing of the action. 

A summary of the comment and EPA’s 

response to the comment are provided 

below. 

II. EPA’s Response to Comment 

The Commenter supports EPA’s 

proposal to approve the State’s February 

5, 2015, SIP revision but notes that it is 

‘‘very disturbed by rumors that EPA will 

approve and implement this change 

[during the week of July 27, 2015], 

which will be right in the middle of the 

summer fuel season.’’ The Commenter 

‘‘requests that EPA approve and 

implement the Georgia SIP in a manner 

that will not damage the fuel marketing 

industry and ultimately penalize those 

who have complied with the Agency’s 

environmental mandate.’’ 

EPA does not view this comment as 

adverse, and the basis for the 

Commenter’s concerns regarding the 

finalization of the rule during the week 

of July 27, 2015 is unclear. EPA has 

proposed and finalized this action 

under its standard rulemaking process, 

and it will be effective on October 1, 

2015. 

III. Incorporation by Reference 

In this rule, EPA is finalizing 

regulatory text that includes 

incorporation by reference. In 

accordance with requirements of 1 CFR 

51.5, EPA is finalizing the incorporate 

by reference of Georgia Rule 391–3–1- 

.02(2)(mmm), NOX Emissions from 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 80, No. 169 / Tuesday, September 1, 2015 / Rules and Regulations 52629 

Stationary Gas Turbines and Stationary 

Engines used to Generate Electricity. 

EPA has made, and will continue to 

make, these documents generally 

available electronically through 

www.regulations.gov and/or in hard 

copy at the appropriate EPA office (see 

the ADDRESSES section of this preamble 

for more information). 

IV. Final Action 

EPA is taking final action to approve 

Georgia’s February 5, 2015, SIP revision, 

including the section 110(l) 

demonstration that modifying the SIP to 

remove Georgia Rules 391–3–1- 

.02(2)(aaa) and 391–3–1-.02(2)(bbb) and 

revising Georgia Rule 391–3–1- 

.02(2)(mmm) will not interfere with 

attainment or maintenance of any 

NAAQS or with any other applicable 

requirement of the CAA. EPA is also 

taking final action to approve the 

portion of the State’s September 26, 

2006, SIP revision that contains 

structural changes to Georgia Rule 391– 

3–1-.02(2)(mmm). 

V. Statutory and Executive Order 

Reviews 

Under the CAA, the Administrator is 

required to approve a SIP submittal that 

complies with the provisions of the Act 

and applicable federal regulations. See 

42 U.S.C. 7410(k); 40 CFR 52.02(a). 

Thus, in reviewing SIP submissions, 

EPA’s role is to approve state choices, 

provided that they meet the criteria of 

the CAA. Accordingly, this action 

merely approves state law as meeting 

Federal requirements and does not 

propose to impose additional 

requirements beyond those imposed by 

state law. For that reason, this action: 

• Is not a significant regulatory action 

subject to review by the Office of 

Management and Budget under 

Executive Orders 12866 (58 FR 51735, 

October 4, 1993) and 13563 (76 FR 3821, 

January 21, 2011); 

• does not impose an information 

collection burden under the provisions 

of the Paperwork Reduction Act (44 

U.S.C. 3501 et seq.); 

• is certified as not having a 

significant economic impact on a 

substantial number of small entities 

under the Regulatory Flexibility Act (5 

U.S.C. 601 et seq.); 

• does not contain any unfunded 

mandate or significantly or uniquely 

affect small governments, as described 

in the Unfunded Mandates Reform Act 

of 1995 (Pub. L. 104–4); 

• does not have Federalism 

implications as specified in Executive 

Order 13132 (64 FR 43255, October 7, 

1999); 

• is not an economically significant 

regulatory action based on health or 

safety risks subject to Executive Order 

13045 (62 FR 19885, April 23, 1997); 

• is not a significant regulatory action 

subject to Executive Order 13211 (66 FR 

28355, May 22, 2001); 

• is not subject to requirements of 

Section 12(d) of the National 

Technology Transfer and Advancement 

Act of 1995 (15 U.S.C. 272 note) because 

application of those requirements would 

be inconsistent with the CAA; and 

• does not provide EPA with the 

discretionary authority to address, as 

appropriate, disproportionate human 

health or environmental effects, using 

practicable and legally permissible 

methods, under Executive Order 12898 

(59 FR 7629, February 16, 1994). 

In addition, the SIP is not approved 

to apply on any Indian reservation land 

or in any other area where EPA or an 

Indian tribe has demonstrated that a 

tribe has jurisdiction. In those areas of 

Indian country, the rule does not have 

tribal implications as specified by 

Executive Order 13175 (65 FR 67249, 

November 9, 2000) nor will it impose 

substantial direct costs on tribal 

governments or preempt tribal law.

Dallas/Fort Worth 1997 8-Hour Ozone 

Nonattainment Area; Determination of 

Attainment of the 1997 Ozone Standard 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is disapproving revisions 

to the Texas State Implementation Plan 

(SIP) submitted to meet certain 

requirements under section 182(c) of the 

Clean Air Act (CAA) for the Dallas/Fort 

Worth (DFW) nonattainment area under 

the 1997 8-hour ozone National 

Ambient Air Quality Standard (NAAQS 

or standard). The revisions address the 

attainment demonstration submitted on 

January 17, 2012, by the Texas 

Commission on Environmental Quality 

(TCEQ) for the DFW Serious 

nonattainment area. The EPA has also 

determined that the DFW nonattainment 

area is currently attaining the 1997 

ozone NAAQS. This determination is 

based upon complete, quality-assured 

and certified ambient air monitoring 

data that show the area has monitored 

attainment of the 1997 ozone NAAQS 

for the 2012–2014 monitoring period. 

Thus, the requirements to submit an 

attainment demonstration and other 

planning SIPs related to attainment of 

the 1997 ozone NAAQS, and the 

sanctions clock and the EPA’s obligation 

to promulgate an attainment 

demonstration Federal Implementation 

Plan (FIP) for the DFW area are 

suspended for so long as the area 

continues to attain the 1997 ozone 

NAAQS. 

DATES: This final rule is effective on 

October 1, 2015.

and ‘‘our’’ means the EPA. 

I. Background 

The background for this action is 

discussed in detail in our April 28, 2015 

Proposal (80 FR 23487). In that notice, 

we proposed to disapprove the TCEQ’s 

8-hour ozone attainment demonstration 

for the DFW Serious nonattainment area 

because the area failed to attain the 1997 

ozone NAAQS by the June 15, 2013 

attainment date.1 Our analysis and 

findings are discussed in the proposed 

rulemaking. We also proposed to 

determine that the DFW ozone 

nonattainment area is currently in 

attainment of the 1997 ozone standard
