II. Analysis of the State’s Submittal 

III. Final Action 

IV. Statutory and Executive Order Reviews 

I. Background 

Sections 108 and 109 of the Clean Air 

Act (CAA or Act) govern the 

establishment, review, and revision, as 

appropriate, of the NAAQS to protect 

public health and welfare. The CAA 

requires periodic review of the air 

quality criteria—the science upon 

which the standards are based—and the 

standards themselves. EPA’s regulatory 

provisions that govern the NAAQS are 

found at 40 CFR Part 50—National 

Primary and Secondary Ambient Air 

Quality Standards. In this rulemaking, 

EPA is proposing to approve portions of 

Georgia’s September 15, 2008, August 

30, 2010 (two submittals), and 

December 15, 2011, submissions 

amending the State’s rules identifying 

the current NAAQS table for sulfur 

dioxide, nitrogen dioxide, ozone, lead 

and particulate matter that are found at 

Rule 391–3–1–.02(4)b, c, e, f, and g. The 

SIP submissions amending Georgia’s 

rules to incorporate the NAAQS can be 

found in the Docket for this proposed 

rulemaking at www.regulations.gov and 

are summarized below. The remainder 


erowe on DSK2VPTVN1PROD with RULES
Federal Register / Vol. 78, No. 95 / Thursday, May 16, 2013 / Rules and Regulations 28745 

1On September 15, 2008, Georgia submitted to 

EPA a SIP for miscellaneous revisions/Title V 

programs. EPA took action on a portion of Georgia’s 

September 15, 2008, regarding the RACT (y), (ii), 

(kkk) and published in the Federal Register on 

September 28, 2012 (77 FR 59554). Action on the 

remaining portions of the September 15, 2008, 

submittal is still under consideration and will be 

addressed in a separate action. 

of Georgia’s September 15, 2008,1

August 30, 2010 (two submittals), and 

December 15, 2011, SIP revisions are 

being considered in a separate 

rulemaking. 

II. Analysis of the State’s Submittal 

a. Sulfur Dioxide 

On June 22, 2010, EPA revised the 

primary NAAQS for the 1-hour sulfur 

dioxide to 75 parts per billion (ppb). See 

75 FR 35520. Accordingly, in a 

December 15, 2011, SIP submission, 

Georgia updated state rule 391–3–1– 

.02(4)(b) ‘‘Sulfur Dioxide’’ to be 

consistent with the NAAQS that were 

promulgated in 2010. EPA has reviewed 

this revision to Georgia’s rule for sulfur 

dioxide and has made the determination 

that this change is consistent with 

federal regulations; thus, EPA is 

approving this change to Georgia’s SIP. 

b. Nitrogen Dioxide 

On October 8, 1996, EPA revised the 

primary and secondary NAAQS for the 

annual nitrogen dioxide to 53 ppb. See 

61 FR 52852. On February 9, 2010, EPA 

revised the primary NAAQS for the 1- 

hour nitrogen dioxide to 100 ppb. See 

75 FR 6474. Accordingly, in a December 

15, 2011, SIP submission, Georgia 

updated state rule 391–3–1–.02(4)(g) 

‘‘Nitrogen Dioxide’’ to be consistent 

with the NAAQS that were promulgated 

in 1996 and 2010 for the primary and 

secondary annual and primary 1-hour, 

respectively. EPA has reviewed the 

changes to Georgia’s rule for nitrogen 

dioxide and has made the determination 

that the changes are consistent with 

federal regulations; thus, EPA is 

approving the changes to Georgia’s SIP. 

c. Ozone 

On March 27, 2008, EPA revised the 

primary and secondary NAAQS for the 

8-hour ozone to 75 ppb to provide 

increased protection of public health 

and welfare, respectively. See 73 FR 

16436. Accordingly, in a August 30, 

2010, SIP submission, Georgia updated 

state rule 391–3–1–.02(4)(e) ‘‘Ozone’’ to 

update the definition for ozone to be 

consistent with the 8-hour ozone 

NAAQS that were promulgated in 2008. 

EPA has reviewed this revision to 

Georgia’s rule for ozone and has made 

the determination that this change is 

consistent with federal regulations; 

thus, EPA is approving this change to 

Georgia’s SIP. 

d. Lead 

On November 12, 2008, EPA revised 

the lead NAAQS from 1.5 micrograms 

per cubic meter (mg/m3) to 0.15 mg/m3

based on a rolling 3-month average for 

both the primary and secondary 

standards. See 73 FR 66964. 

Accordingly, in a August 30, 2010, SIP 

submission, Georgia updated state rule 

391–3–.02(4)(f) ‘‘Lead’’ to update the 

definition for lead to be consistent with 

the NAAQS that were promulgated in 

2008. EPA has reviewed this revision to 

Georgia’s rule for lead and has made the 

determination that this change is 

consistent with federal regulations; 

thus, EPA is approving this change to 

Georgia’s SIP. 

e. Particulate Matter 

On October 17, 2006, EPA retained 

the annual average NAAQS at 15 mg/m3

but revised the 24-hour NAAQS to 35 

mg/m3, based again on the 3-year average 

of the 98th percentile of 24-hour 

concentrations. Under EPA regulations 

at 40 CFR part 50, the primary and 

secondary 2006 24-hour PM2.5 NAAQS 

are attained when the annual arithmetic 

mean concentration, as determined in 

accordance with 40 CFR part 50, 

Appendix N, is less than or equal to 35 

mg/m3 at all relevant monitoring sites in 

the subject area over a 3-year period. 

See 71 FR 61144. EPA has previously 

approved Georgia’s retainment of the 

annual average NAAQS at 15 mg/m3. See 

75 FR 6309, February 9, 2010. 

Accordingly, in a September 15, 2008, 

and August 30, 2010, SIP submissions, 

Georgia updated state rule 391–3–1- 

.02(4)(c) ‘‘Particulate Matter’’ to update 

the definition for 24-hour and 

significant digits for the annual PM2.5

NAAQS, respectively, to be consistent 

with the NAAQS that were promulgated 

in 2006. EPA has reviewed this revision 

to Georgia’s rule for the 24-hour and 

annual PM2.5 NAAQS and has made the 

determination that this change is 

consistent with federal regulations; 

thus, EPA is approving this change to 

Georgia’s SIP. 

Additionally, on October 17, 2006, 

EPA revoked the PM10 annual NAAQS 

of 50 mg/m3, while keeping in place the 

24-hour PM10 NAAQS of 150 mg/m3. See 

71 FR 61144. Accordingly, in a August 

30, 2010, SIP submission, Georgia 

updated state rule 391–3–1–.02(4)(c) 

‘‘Particulate Matter’’ to update the 

definition for the PM10 NAAQS to be 

consistent with the NAAQS that were 

promulgated in 2006. EPA has reviewed 

this revision to Georgia’s rule for the 24- 

hour PM10 NAAQS and has made the 

determination that this change is 

consistent with federal regulations; 

thus, EPA is approving this change to 

Georgia’s SIP. 

III. Final Action 

EPA is approving the aforementioned 

changes to the State of Georgia SIP, 

because it is consistent with EPA’s 

standards for sulfur dioxide, nitrogen 

dioxide, ozone, lead and particulate 

matter. EPA is publishing this rule 

without prior proposal because the 

Agency views this as a noncontroversial 

submittal and anticipates no adverse 

comments. However, in the proposed 

rules section of this Federal Register 

publication, EPA is publishing a 

separate document that will serve as the 

proposal to approve the SIP revision 

should adverse comments be filed. This 

rule will be effective July 15, 2013 

without further notice unless the 

Agency receives adverse comments by 

June 17, 2013. 

If EPA receives such comments, then 

EPA will publish a document 

withdrawing the final rule and 

informing the public that the rule will 

not take effect. All public comments 

received will then be addressed in a 

subsequent final rule based on the 

proposed rule. EPA will not institute a 

second comment period. Parties 

interested in commenting should do so 

at this time. If no such comments are 

received, the public is advised that this 

rule will be effective on July 15, 2013 

and no further action will be taken on 

the proposed rule. 

IV. Statutory and Executive Order 

Reviews 

Under the CAA, the Administrator is 

required to approve a SIP submission 

that complies with the provisions of the 

Act and applicable federal regulations. 

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 

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 Order 12866 (58 FR 51735, 

October 4, 1993); 

• 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 


erowe on DSK2VPTVN1PROD with RULES
28746 Federal Register / Vol. 78, No. 95 / Thursday, May 16, 2013 / Rules and Regulations 

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, August 10, 

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, this rule does not have 

tribal implications as specified by 

Executive Order 13175 (65 FR 67249, 

November 9, 2000), because the SIP is 

not approved to apply in Indian country 

located in the state, and EPA notes that 

it will not impose substantial direct 

costs on tribal governments or preempt 

tribal law. 

The Congressional Review Act, 5 

U.S.C. 801 et seq., as added by the Small 

Business Regulatory Enforcement 

Fairness Act of 1996, generally provides 

that before a rule may take effect, the 

agency promulgating the rule must 

submit a rule report, which includes a 

copy of the rule, to each House of the 

Congress and to the Comptroller General 

of the United States. EPA will submit a 

report containing this action and other 

required information to the U.S. Senate, 

the U.S. House of Representatives, and 

the Comptroller General of the United 

States prior to publication of the rule in 

the Federal Register. A major rule 

cannot take effect until 60 days after it 

is published in the Federal Register. 

This action is not a ‘‘major rule’’ as 

defined by 5 U.S.C. 804(2). 

Under section 307(b)(1) of the CAA, 

petitions for judicial review of this 

action must be filed in the United States 

Court of Appeals for the appropriate 

circuit by July 15, 2013. Filing a petition 

for reconsideration by the Administrator 

of this final rule does not affect the 

finality of this action for the purposes of 

judicial review nor does it extend the 

time within which a petition for judicial 

review may be filed, and shall not 

postpone the effectiveness of such rule 

or action. Parties with objections to this 

direct final rule are encouraged to file a 

comment in response to the parallel 

notice of proposed rulemaking for this 

action published in the proposed rules 

section of today’s Federal Register; 

rather than file an immediate petition 

for judicial review of this direct final 

rule, so that EPA can withdraw this 

direct final rule and address the 

comment in the proposed rulemaking. 

This action may not be challenged later 

in proceedings to enforce its 

requirements. See section 307(b)(2).

found in the Docket for this proposed 

rulemaking at www.regulations.gov and

II. Analysis of the State’s Submittal 

a. Ozone 

On March 27, 2008, EPA revised the 

primary and secondary NAAQS for the 

8-hour ozone to 75 parts per billion 

(ppb) to provide increased protection of 

public health and welfare, respectively. 

See 73 FR 16436. Accordingly, in a 

February 3, 2010, SIP submission, North 

Carolina updated state rule 15A NCAC 

02D .0405 ‘‘Ozone’’ to update the 

definition for ozone to be consistent 

with the 8-hour ozone NAAQS that 

were promulgated in 2008. EPA has 

reviewed this revision to North 

Carolina’s rule for ozone and has made 

the determination that this change is 

consistent with federal regulations; thus
