40 CFR Part 52 

[EPA–R05–OAR–2010–0999; FRL–9304–8] 

Approval and Promulgation of Air 

Quality Implementation Plans; Indiana 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Direct final rule. 

SUMMARY: EPA is approving a request 

submitted by the Indiana Department of 

Environmental Management (IDEM) on 

November 24, 2010, to revise the 

Indiana State Implementation Plan 

(SIP). The submission revises the 

Indiana Administrative Code (IAC) by 

amending and updating the definition of 

‘‘References to the Code of Federal 

Regulations,′′ to refer to the 2009 

edition. The submission also makes a 

minor revision to the definition of 

‘‘Nonphotochemically reactive 

hydrocarbons′′ or ‘‘negligibly 

photochemically reactive compounds′′ 

by deleting an outdated Federal 

Register citation. 

DATES: This rule is effective on July 12, 

2011, unless EPA receives adverse 

written comments by June 13, 2011. If 

EPA receives adverse comments, EPA 

will publish a timely withdrawal of the 

rule in the Federal Register and inform 

the public that the rule will not take 

effect.

docket without change and may be 

made available online at http:// 

www.regulations.gov, including any 

personal information provided, unless 

the comment includes information 

claimed to be Confidential Business 

Information (CBI) or other information 

whose disclosure is restricted by statute. 

Do not submit information that you 

consider to be CBI or otherwise 

protected through http:// 

www.regulations.gov or e-mail. The 

http://www.regulations.gov Web site is 

an ‘‘anonymous access′′ system, which 

means EPA will not know your identity 

or contact information unless you 

provide it in the body of your comment. 

If you send an e-mail comment 

directly to EPA without going through 

http://www.regulations.gov your e-mail 

address will be automatically captured 

and included as part of the comment 

that is placed in the public docket and 

made available on the Internet. If you 

submit an electronic comment, EPA 

recommends that you include your 

name and other contact information in 

the body of your comment and with any 

disk or CD–ROM you submit. If EPA 

cannot read your comment due to 

technical difficulties and cannot contact 

you for clarification, EPA may not be 

able to consider your comment. 

Electronic files should avoid the use of 

special characters, any form of 

encryption, and be free of any defects or 

viruses. 

Docket: All documents in the docket 

are listed in the http:// 

www.regulations.gov index. Although 

listed in the index, some information is 

not publicly available, e.g., CBI or other 

information whose disclosure is 

restricted by statute. Certain other 

material, such as copyrighted material, 

will be publicly available only in hard 

copy. Publicly available docket 

materials are available either

SUPPLEMENTARY INFORMATION: 

Throughout this document whenever 

‘‘we,′′ ‘‘us,′′ or ‘‘our′′ is used, we mean 

EPA. This supplementary information 

section is arranged as follows: 

I. What is the background for this action? 

A. When did the State submit the 

requested SIP revision to EPA? 

B. Did Indiana hold public hearings on this 

SIP revision? 

II. What revision did the State request be 

incorporated into the SIP? 

III. What action is EPA taking? 

IV. Statutory and Executive Order Reviews 

I. What is the background for this 

action? 

A. When did the State submit the 

requested SIP revision to EPA? 

IDEM submitted the SIP revision on 

November 24, 2010. 

B. Did Indiana hold public hearing on 

this SIP revision? 

IDEM held a public hearing on June 

2, 2010. IDEM did not receive any 

public comments concerning the SIP 

revision. 

II. What revision did the State request 

be incorporated into the SIP? 

The State has requested that SIP 

revision include: (1) updated references 

to the CFR at 326 IAC 1–1–3, and (2) the 

deletion of a reference to Federal 

Register citation at 326 IAC 1–2–48 to 

clarify that the compounds dimethyl 

carbonate and propylene carbonate are 

excluded from the definition of volatile 

organic compound (VOC). 

Rule 326 IAC 1–1–3, definition of 

‘‘References to the Code of Federal 

Regulations.′′ IDEM updated the 

reference to the CFR in 326 IAC 1–1–3 

from the 2008 edition to the 2009 

edition. This is solely an administrative 

change that allows Indiana to reference 

a more current version of the CFR. By 

amending 326 IAC 1–1–3 to reference 

the most current version of the CFR, 

Title 326 of the IAC will be consistent 

and current with Federal regulations. 

Rule 326 IAC 1–2–48, definition of 

‘‘Nonphotochemically reactive 

hydrocarbons′′ or ‘‘negligibly 

photochemically reactive compounds.′′ 

IDEM has amended 326 IAC 1–2–48 to 

clarify the inclusion of two additional 

compounds to the list of compounds 

that are excluded from the definition of 

VOC by deleting language in section 

WReier-Aviles on DSKGBLS3C1PROD with RULES

Federal Register / Vol. 76, No. 93 / Friday, May 13, 2011 / Rules and Regulations 27905 

(a)(1) that EPA had not previously 

approved and which unnecessarily cited 

a January 21, 2009 Federal Register 

notice (74 FR 3437). Rule 326 IAC 1–2– 

48 (a)(1) now clearly incorporates by 

reference the Federal regulation at 40 

CFR 51.100(s)(1), which lists all the 

negligibly reactive compounds excluded 

from the definition of VOC, and does so 

without any additional qualifying 

citations. 

III. What action is EPA taking today? 

We are approving revisions to the 

Indiana SIP to: (1) Update the definition 

at 326 IAC 1–1–3, ‘‘References to the 

Code of Federal Regulations,′′ to refer to 

the 2009 edition, and (2) delete language 

that references the Federal Register in 

326 IAC 1–2–48(a)(1), that are 

redundant as a result of the update to 

the references to CFR. 

We are publishing this action without 

prior proposal because we view this as 

a noncontroversial amendment and 

anticipate no adverse comments. 

However, in the proposed rules section 

of this Federal Register publication, we 

are publishing a separate document that 

will serve as the proposal to approve the 

state plan if relevant adverse written 

comments are filed. This rule will be 

effective July 12, 2011 without further 

notice unless we receive relevant 

adverse written comments by June 13, 

2011. If we receive such comments, we 

will withdraw this action before the 

effective date by publishing a 

subsequent document that will 

withdraw the final action. All public 

comments received will then be 

addressed in a subsequent final rule 

based on the proposed action. EPA will 

not institute a second comment period. 

Any parties interested in commenting 

on this action should do so at this time. 

If we do not receive any comments, this 

action will be effective July 12, 2011. 

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 Clean Air 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 July 12, 2011. 

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 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).)

I. Background and Purpose 

On April 14, 2010, the Massachusetts 

Department of Environmental Protection 

(DEP) submitted a revision to its State 

Implementation Plan (SIP) for 

Massachusetts. The SIP revision 

consists of a minor modification to the 

carbon monoxide (CO) maintenance 

plan for Lowell, Massachusetts. (A 

redesignation request and a 

maintenance plan for the Lowell CO 

nonattainment area were approved by 

EPA on February 19, 2002 (67 FR 

7272).) The modification changes the 

triggering mechanism which will be 

used by the State to determine if 

contingency measures need to be 

implemented in Lowell. 

On February 17, 2011, EPA proposed 

approval of this SIP revision (76 FR 

9281). EPA received no comments on 

the proposed rulemaking. 

II. What action is EPA taking? 

EPA is approving revisions to the 

Lowell carbon monoxide maintenance 

plan submitted by the State of 

Massachusetts on April 14, 2010. 

Specifically, EPA is approving the 

State’s modification of the portion of the 

maintenance plan used to determine 

when contingency measures need to be 

triggered to reduce CO concentrations in 

Lowell. This action will allow the 

discontinuation of CO monitoring in the 

Lowell maintenance area. Other specific 

requirements of the revised carbon 

monoxide plan for Lowell, 

Massachusetts and the rationale for 

EPA’s proposed action are explained in 

the Notice of Proposed Rulemaking 

(NPR) and will not be restated here. 

III. Summary of SIP Revision 

On April 14, 2010, the Massachusetts 

Department of Environmental Protection 

submitted a SIP revision to EPA that 

contains a modification to its CO 

maintenance plan for the Lowell CO 

maintenance area. The modifications to 

the maintenance plan change the 

triggering mechanism by which 

contingency measures would be 

implemented and will allow the State to 

discontinue CO monitoring in the 

Lowell maintenance area. CO 

concentrations measured in Lowell have
