I. Background

    The background for today's action is discussed in detail in our 
February 9, 2012, proposal (77 FR 6711). In that notice, we proposed to 
partially approve and partially disapprove submittals from the State of 
Arkansas, pursuant to the CAA, that address the infrastructure elements 
specified in the CAA section 110(a)(2), necessary to implement, 
maintain, and enforce the 1997 8-hour ozone, the 1997 and 2006 
PM2.5 NAAQS. Those submittals are dated December 17, 2007, 
March 28, 2008, and September 16, 2009, respectively. We noted that 
those submittals did not include revisions to the SIP, but documented 
how the current Arkansas SIP already included the required 
infrastructure elements. Therefore, we proposed to find that the 
following section 110(a)(2) elements were contained in the current 
Arkansas SIP and provided the infrastructure for implementing the 1997 
8-hour ozone standard: CAA Sections 110(a)(2)(A), (B), (E), (F), (G), 
(H), (K), (L), (M), and portions of (C), (D)(ii), and (J). EPA also 
proposed to find that the following section 110(a)(2) elements were 
contained in the current Arkansas SIP and provided the infrastructure 
for implementing the 1997 and 2006 PM2.5 standards: CAA 
Sections 110(a)(2)(A), (B), (E), (F), (G), (H), (K), (L), and (M). EPA 
also proposed to find that the current Arkansas SIP does not meet the 
infrastructure requirements for the 1997 8-hour ozone NAAQS and the 
1997 and 2006 PM2.5 NAAQS at 110(a)(2) for portions of (C), 
(D)(ii), and (J) because the EPA-approved SIP prevention of significant 
deterioration (PSD) program does not apply to greenhouse gas (GHG) 
emitting sources. We also proposed to find that the current Arkansas 
SIP does not meet the infrastructure requirements for the 1997 and 2006 
PM2.5 NAAQS at 110(a)(2) for (C), (D)(ii), and (J) because 
Arkansas has not submitted the PSD SIP revision required by EPA's 
Implementation of the New Source Review (NSR) Program for Particulate 
Matter Less Than 2.5 Micrometers (73 FR 28321, May 16, 2008). Further, 
for the 1997 8-hour ozone NAAQS, we proposed to partially approve and 
partially disapprove the provisions of SIP submissions intended to 
satisfy the section 110(a)(2)(D)(i)(II) infrastructure element 
pertaining to emissions from sources in Arkansas not interfering with 
measures required in the SIP of any other State under part C of the CAA 
to prevent significant deterioration of air quality. For the 2006 
PM2.5 NAAQS, we proposed to disapprove the provisions of SIP 
submissions intended to satisfy this section 110(a)(2)(D)(i)(II) 
infrastructure element. Finally, for purposes of the 1997 8-hour ozone 
NAAQS, EPA proposed to approve four severable portions of SIP revisions 
to modify the Arkansas PSD SIP to include NOX as an ozone 
precursor.
    Our February 9, 2012, proposal provides a detailed description of 
the submittals and the rationale for EPA's proposed actions, together 
with a discussion of the opportunity to comment. The public comment 
period for these actions closed on March 12, 2012, and we did not 
receive any comments.

II. Final Action

    We are partially approving and partially disapproving the 
submittals provided by the State of Arkansas to demonstrate that the 
Arkansas SIP meets the requirements of Section 110(a)(1) and (2) of the 
Act for the 1997 ozone and 1997 and 2006 PM2.5 NAAQS. For 
the 1997 ozone standard, we are finding that the current Arkansas SIP 
meets the infrastructure elements listed below:
    Emission limits and other control measures (110(a)(2)(A) of the 
Act);
    Ambient air quality monitoring/data system (110(a)(2)(B) of the 
Act);
    Program for enforcement of control measures (110(a)(2)(C) of the 
Act), except for the portion that addresses GHGs;
    Interstate Transport, pursuant to section 110(a)(2)(D)(ii) of the 
Act, except for the portion that addresses GHGs;
    Adequate resources (110(a)(2)(E) of the Act);
    Stationary source monitoring system (110(a)(2)(F) of the Act);
    Emergency power (110(a)(2)(G) of the Act);
    Future SIP revisions (110(a)(2)(H) of the Act);
    Consultation with government officials (110(a)(2)(J) of the Act);
    Public notification (110(a)(2)(J) of the Act);
    Prevention of significant deterioration and visibility protection 
(110(a)(2)(J) of the Act), except for the portion that addresses GHGs;
    Air quality modeling data (110(a)(2)(K) of the Act);
    Permitting fees (110(a)(2)(L) of the Act); and
    Consultation/participation by affected local entities (110(a)(2)(M) 
of the Act).
    For the 1997 ozone standard, we are finding that the current 
Arkansas SIP does not meet the infrastructure elements listed below:
    Program for enforcement of control measures (110(a)(2)(C) of the 
Act), only as it relates to GHGs;
    Interstate transport, pursuant to section 110(a)(2)(D)(ii) of the 
Act, only as it relates to GHGs; and
    Prevention of significant deterioration (110(a)(2)(J) of the Act), 
only as it relates to GHGs.
    We are also approving the Arkansas Interstate Transport SIP 
provisions that

[[Page 50035]]

address the requirement of section 110(a)(2)(D)(i)(II) that emissions 
from sources in Arkansas do not interfere with measures required in the 
SIP of any other State under part C of the CAA to prevent significant 
deterioration of air quality, except as they relate to GHGs for the 
1997 ozone NAAQS.
    We are disapproving the portion of the Arkansas Interstate 
Transport SIP provisions that address the requirement of section 
110(a)(2)(D)(i)(II), as it relates to GHGs, that emissions from sources 
in Arkansas do not interfere with measures required in the SIP of any 
other State under part C of the CAA to prevent significant 
deterioration of air quality, for the 1997 ozone NAAQS.
    For the 1997 and 2006 PM2.5 standards, we are finding 
that the current Arkansas SIP meets the infrastructure elements listed 
below:
    Emission limits and other control measures (110(a)(2)(A) of the 
Act);
    Ambient air quality monitoring/data system (110(a)(2)(B) of the 
Act);
    Adequate resources (110(a)(2)(E) of the Act);
    Stationary source monitoring system (110(a)(2)(F) of the Act);
    Emergency power (110(a)(2)(G) of the Act);
    Future SIP revisions (110(a)(2)(H) of the Act);
    Consultation with government officials (110(a)(2)(J) of the Act);
    Public notification (110(a)(2)(J) of the Act);
    Air quality modeling data (110(a)(2)(K) of the Act);
    Permitting fees (110(a)(2)(L) of the Act); and
    Consultation/participation by affected local entities (110(a)(2)(M) 
of the Act).
    For the 1997 and 2006 PM2.5 standards, we are finding 
that the current Arkansas SIP does not address the 110(a)(2) 
infrastructure elements listed below:
    Program for enforcement of control measures (110(a)(2)(C) of the 
Act);
    Interstate Transport, pursuant to section 110(a)(2)(D)(ii) of the 
Act; and
    Prevention of significant deterioration and visibility protection 
(110(a)(2)(J) of the Act).
    We are also disapproving the portion of the Arkansas Interstate 
Transport SIP that addresses the requirement of section 
110(a)(2)(D)(i)(II)--that emissions from sources in Arkansas do not 
interfere with measures required in the SIP of any other State under 
part C of the CAA to prevent significant deterioration of air quality--
for the 2006 PM2.5 NAAQS.
    Under section 110(c) of the Act, disapproval of a SIP in whole or 
in part requires EPA to promulgate a federal implementation plan (FIP) 
at any time within two years following final disapproval, unless the 
State submits a plan or plan revision that corrects the deficiency--and 
the EPA approves the plan or plan revision--before the EPA promulgates 
such FIP. This two-year period is commonly referred to as the ``FIP 
clock.'' Here, based on Arkansas's failure to submit the required 
PM2.5 PSD SIP revision, and because Arkansas cannot issue 
permits for GHG emissions, we are disapproving for the 1997 and 2006 
PM2.5 standard and partially disapproving for the 1997 ozone 
NAAQS certain severable elements of the Arkansas infrastructure SIP. 
Accordingly, EPA is required by law to promulgate a FIP at any time 
within two years of this final rulemaking, unless Arkansas submits and 
we approve a new SIP or SIP revisions that correct the deficiencies, or 
unless EPA has already fulfilled its FIP obligation.
    EPA is also approving the following revisions to APCEC Regulation 
19, Chapter 9, submitted by the State of Arkansas on February 17, 2010:
    1. The substantive change adding NOX to the definition 
of Major Modification through incorporation by reference of 40 CFR 
52.21(b) and 40 CFR 51.301 as of November 29, 2005.
    2. The substantive change adding NOX to the definition 
of Major Stationary Source through incorporation by reference of 40 CFR 
52.21(b) and 40 CFR 51.301 as of November 29, 2005.
    3. The substantive change adding NOX as a precursor to 
the table's criteria and other pollutants listing for ozone through 
incorporation by reference of 40 CFR 52.21(b)(23)(i).
    4. The substantive change allowing for an exemption with respect to 
ozone monitoring for a source with a net emissions increase less than 
100 tpy of NOX through incorporation by reference of 40 CFR 
52.21(i)(5)(i).
    EPA is taking these actions in accordance with section 110 and part 
C of the Act and EPA's regulations and consistent with EPA guidance. We 
are also making ministerial corrections to the attainment status table 
in 40 CFR 81.304 to accurately reflect the redesignation date of 
Crittenden County, Arkansas to attainment for the 1997 8-hour ozone 
standard. On March 24, 2010, we redesignated the county with an 
effective date of April 23, 2010 (75 FR 14077).

III. 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 act on State law as meeting 
Federal requirements and does not impose additional requirements beyond 
those imposed by State law.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    This action is not a ``significant regulatory action'' under the 
terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is 
therefore not subject to review under Executive Orders 12866 and 13563 
(76 FR 3821, January 21, 2011).

B. Paperwork Reduction Act

    This action does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq., 
because this SIP partial approval/partial disapproval under section 110 
and subchapter I, part D of the CAA will not in-and-of itself create 
any new information collection burdens but simply disapproves certain 
State requirements for inclusion into the SIP. Burden is defined at 5 
CFR 1320.3(b).

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to conduct a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements unless the agency certifies 
that the rule will not have a significant economic impact on a 
substantial number of small entities. Small entities include small 
businesses, small not-for-profit enterprises, and small governmental 
jurisdictions. For purposes of assessing the impacts of today's rule on 
small entities, small entity is defined as: (1) A small business as 
defined by the Small Business Administration's (SBA) regulations at 13 
CFR 121.201; (2) a small governmental jurisdiction that is a government 
of a city, county, town, school district, or special district with a 
population of less than 50,000; and (3) a small organization that is 
any not-for-profit enterprise which is independently owned and operated 
and is not dominant in its field.
    After considering the economic impacts of today's rule on small 
entities, I certify that this action will not have a significant impact 
on a substantial number of small entities. This rule does not impose 
any requirements or create impacts on small entities. This SIP partial 
approval/partial disapproval under section 110 and subchapter I, part D 
of the CAA will not in-and-of itself

[[Page 50036]]

create any new requirements but simply approves, in part, and 
disapproves, in part, certain State requirements for inclusion into the 
SIP. Accordingly, it affords no opportunity for EPA to fashion for 
small entities less burdensome compliance or reporting requirements or 
timetables or exemptions from all or part of the rule. The fact that 
the CAA prescribes that various consequences (e.g., a FIP) may or will 
flow from this partial disapproval does not mean that EPA either can or 
must conduct a regulatory flexibility analysis for this action. 
Therefore, this action will not have a significant economic impact on a 
substantial number of small entities.

D. Unfunded Mandates Reform Act

    This action contains no Federal mandates under the provisions of 
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 
1531-1538 for State, local, or tribal governments or the private 
sector. EPA has determined that the action does not include a Federal 
mandate that may result in estimated costs of $100 million or more to 
either State, local, or tribal governments in the aggregate, or to the 
private sector. This action partially approves and partially 
disapproves pre-existing requirements under State or local law, and 
imposes no new requirements. Accordingly, no additional costs to State, 
local, or tribal governments, or to the private sector, result from 
this action.

E. Executive Order 13132, Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that have ``substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.''
    This action does not have federalism implications. It will not have 
substantial direct effects on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government, as 
specified in Executive Order 13132, because it merely partially 
approves and partially disapproves certain State requirements for 
inclusion into the SIP and does not alter the relationship or the 
distribution of power and responsibilities established in the CAA. 
Thus, Executive Order 13132 does not apply to this action.

F. Executive Order 13175, Coordination With Indian Tribal Governments

    This action does not have tribal implications, as specified in 
Executive Order 13175 (65 FR 67249, November 9, 2000), because the 
action EPA is finalizing neither imposes substantial direct compliance 
costs on tribal governments, nor preempts tribal law. Therefore, the 
requirements of section 5(b) and 5(c) of the Executive Order do not 
apply to this rule. Consistent with EPA policy, EPA nonetheless is 
offering consultation to Tribes regarding this rulemaking action. EPA 
will respond to relevant comments in the final rulemaking action.

G. Executive Order 13045, Protection of Children From Environmental 
Health Risks and Safety Risks

    EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) 
as applying only to those regulatory actions that concern health or 
safety risks, such that the analysis required under section 5-501 of 
the Executive Order has the potential to influence the regulation. This 
action is not subject to Executive Order 13045 because it is not an 
economically significant regulatory action based on health or safety 
risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997). 
This SIP partial approval/disapproval under section 110 and subchapter 
I, part D of the CAA will not in-and-of itself create any new 
regulations but simply partially approves and partially disapproves 
certain State requirements for inclusion into the SIP.

H. Executive Order 13211, Actions That Significantly Affect Energy 
Supply, Distribution or Use

    This action is not subject to Executive Order 13211 (66 FR 28355, 
May 22, 2001) because it is not a significant regulatory action under 
Executive Order 12866.

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (``NTTAA''), Public Law 104-113, section 12(d) (15 U.S.C. 
272 note) directs EPA to use voluntary consensus standards in its 
regulatory activities unless to do so would be inconsistent with 
applicable law or otherwise impractical. Voluntary consensus standards 
are technical standards (e.g., materials specifications, test methods, 
sampling procedures, and business practices) that are developed or 
adopted by voluntary consensus standards bodies. NTTAA directs EPA to 
provide Congress, through OMB, explanations when the Agency decides not 
to use available and applicable voluntary consensus standards.
    The EPA believes that this action is not subject to requirements of 
Section 12(d) of NTTAA because application of those requirements would 
be inconsistent with the CAA.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629, February 16, 1994) establishes 
Federal executive policy on environmental justice. Its main provision 
directs Federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on minority populations and low-income 
populations in the United States.
    EPA lacks the discretionary authority to address environmental 
justice in this action. In reviewing SIP submissions, EPA's role is to 
approve or disapprove state choices, based on the criteria of the CAA. 
Accordingly, this action merely partially approves and partially 
disapproves certain State requirements for inclusion into the SIP under 
section 110 and subchapter I, part D of the CAA and will not in-and-of 
itself create any new requirements. Accordingly, it 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.

K. Congressional Review Act

    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

[[Page 50037]]

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).

L. Judicial Review

    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 October 19, 2012. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action for the purpose 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).)
