ENVIRONMENTAL PROTECTION AGENCY

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outdated Federal Register citation.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.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R05-
OAR-2010-0999 by one of the following methods:

    Instructions: Direct your comments to Docket ID No. EPA-R05-OAR-
2010-0999. EPA's policy is that all comments received will be included 
in the public 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

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 electronically 
in http://www.regulations.gov or in hard copy at the U.S. Environmental 
Protection Agency, Region 5, Air and Radiation Division, 77 West 
Jackson Boulevard, Chicago, Illinois 60604. This facility is open from 
8:30 a.m. to 4:30 p.m., Monday through Friday, excluding Federal

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

[[Page 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).)
