ACTION: Final rule. 

SUMMARY: EPA is approving the State 

Implementation Plan (SIP) submission 

from the State of North Dakota to 

demonstrate that the SIP meets the 

infrastructure requirements of the Clean 

Air Act (CAA) for the National Ambient 

Air Quality Standards (NAAQS) 

promulgated for fine particulate matter 

(PM2.5) on July 18, 1997 and on October 

17, 2006. The CAA requires that each 

state, after a new or revised NAAQS is 

promulgated, review their SIPs to 

ensure that they meet infrastructure 

requirements. The State of North Dakota 

submitted certifications of their 

infrastructure SIP on August 12, 2010 

and May 22, 2012 for the 2006 PM2.5

NAAQS. In addition, the State of North 

Dakota submitted a certification of their 

infrastructure SIP on May 25, 2012 for 

the 1997 PM2.5 NAAQS. EPA is also 

approving SIP revisions that the State of 

North Dakota submitted that update the 

Prevention of Significant Deterioration 

(PSD) program and the SIP provisions 

regarding state boards. 

DATES: Effective Date: This final rule is 

effective August 29, 2013.

I. Background 

Infrastructure requirements for SIPs 

are provided in sections 110(a)(1) and 

(2) of the CAA. Section 110(a)(2) lists 

the specific infrastructure elements that 

a SIP must contain or satisfy. The 

elements that are the subject of this 

action are described in detail in our 

notice of proposed rulemaking (NPR), 

published on May 13, 2013 (78 FR 

27898). 

In the NPR, EPA proposed to approve 

North Dakota’s submissions for the 

following infrastructure elements for the 

1997 and 2006 PM2.5 NAAQS: CAA 

section 110(a)(2)(A), (B), (C) with 

respect to minor NSR and PSD 

requirements, (D)(ii), (E), (F), (G), (H), 

(J), (K), (L), and (M). We proposed to 


emcdonald on DSK67QTVN1PROD with RULES
Federal Register / Vol. 78, No. 146 / Tuesday, July 30, 2013 / Rules and Regulations 45867 

approve North Dakota’s submissions for 

element (D)(i)(II) with respect to PSD 

requirements for the 2006 PM2.5

NAAQS. In conjunction with our action 

on North Dakota’s infrastructure SIP 

submittals, EPA also proposed to 

approve a portion of the State’s January 

24, 2013 submittal revising the State’s 

PSD program: specifically, the portion 

incorporating by reference the text of 40 

CFR part 52, section 21, paragraphs 

(b)(14)(i), (ii), and (iii); (b)(15)(i) and (ii); 

and paragraph (c) as those paragraphs 

existed on January 1, 2012. 

Additionally, EPA proposed to approve 

the portion of the April 8, 2013 

submittal that revised Chapter 2, 

Section 2.15, Respecting Boards. 

Finally, EPA will act separately on 

infrastructure element (D)(i)(I) for the 

2006 PM2.5 NAAQS. 

The approval of the above portion of 

the January 24, 2013 submittal 

incorporates the PM2.5 increments into 

the State’s PSD program and updates the 

program to meet the current 

requirements for all regulated NSR 

pollutants. As a result, North Dakota’s 

SIP satisfies the PSD requirements in 

infrastructure elements (C) and (J). In 

addition, with our approval of the 

portion of the April 8, 2013 submittal 

regarding state boards, the North Dakota 

SIP meets the current requirements for 

section 128 and element (E)(ii) regarding 

disclosure requirements that apply to 

any person that approves permits or 

enforcement orders under North 

Dakota’s implementation of the CAA. 

II. Response to Comments 

No comments were received on our 

May 13, 2013 NPR. 

III. Final Action 

EPA is approving the following 

infrastructure elements for the 1997 and 

2006 PM2.5 NAAQS: CAA 110(a)(2)(A), 

(B), (C) with respect to minor NSR and 

PSD requirements, (D)(ii), (E), (F), (G), 

(H), (J), (K), (L), and (M). EPA is 

approving (D)(i)(II) with respect to PSD 

requirements for the 2006 PM2.5

NAAQS. EPA is approving a portion of 

the State’s January 24, 2013 submittal 

revising the State’s PSD program. 

Specifically, we are approving the 

inclusion into the North Dakota SIP of 

the text of 40 CFR part 52, section 21, 

paragraphs (b)(14)(i), (ii), and (iii); 

(b)(15)(i) and (ii); and paragraph (c) as 

those paragraphs existed on January 1, 

2012. Additionally, EPA is approving 

the portion of the April 8, 2013 

submittal revising Chapter 2, Section 

2.15, Respecting Boards. Finally, EPA 

will act separately on infrastructure 

element (D)(i)(I) for the 2006 p.m. 2.5

NAAQS. 

IV. Statutory and Executive Order 

Reviews 

Under the Clean Air Act, 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 Clean Air Act. 

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 

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 Clean Air Act; 

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 Clean 

Air Act, petitions for judicial review of 

this action must be filed in the United 

States Court of Appeals for the 

appropriate circuit by September 30, 

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. This action may not be 

challenged later in proceedings to 

enforce its requirements. (See section 

307(b)(2).)

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: EPA is taking final action to 

partially approve and partially 

disapprove portions of a State 

Implementation Plan (SIP) submission 

from the State of Montana that are 

intended to demonstrate that its SIP 

meets certain interstate transport 

requirements of the Clean Air Act 

(‘‘Act’’ or ‘‘CAA’’) for the 2006 fine 

particulate matter (‘‘PM2.5’’) National 

Ambient Air Quality Standards 

(‘‘NAAQS’’). Specifically, EPA is 

partially approving and partially 

disapproving the portion of the Montana 

SIP submission that addresses the CAA 

requirement prohibiting emissions from 

Montana sources from significantly 

contributing to nonattainment of the 

2006 PM2.5 NAAQS in any other state or 

interfering with maintenance of the 

2006 PM2.5 NAAQS by any other state. 

EPA is also partially approving and 

partially disapproving the portion of 

Montana’s submission that addresses 

the CAA requirement that SIPs contain 

provisions to insure compliance with 

specific other CAA requirements 

relating to interstate and international 

pollution abatement. These partial 

disapprovals will not trigger an 

obligation for EPA to promulgate a 

Federal Implementation Plan (FIP) to 

address these interstate transport 

requirements as EPA is determining that 

the existing SIP is adequate to meet the 

specific CAA requirements.
