Determination of Nonattainment and Reclassification of the Baton 
Rouge 8-Hour Ozone Nonattainment Area; State of Louisiana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: EPA is finalizing its finding that the Baton Rouge 
``marginal'' 8-hour ozone nonattainment area (hereinafter referred to 
as the Baton Rouge area) did not attain the 8-hour ozone national 
ambient air quality standard (NAAQS or standard) by June 15, 2007, the 
attainment deadline set forth in the Clean Air Act (CAA or the Act) and 
Code of Federal Regulations (CFR) for ``marginal'' nonattainment areas. 
By operation of law, the Baton Rouge area is to be reclassified from a 
``marginal'' to a ``moderate'' 8-hour ozone nonattainment area on the 
effective date of this rule. The new attainment deadline for the 
reclassified Baton Rouge nonattainment area is ``as expeditiously as 
practicable'' but no later than June 15, 2010. In addition, EPA is 
requiring Louisiana to submit State Implementation Plan (SIP) revisions 
addressing the CAA's pollution control requirements for ``moderate'' 8-
hour ozone nonattainment areas no later than January 1, 2009.

DATES: This final rule is effective on April 21, 2008.

ADDRESSES: EPA has established a docket for this action under Docket 
Identification No. EPA-R06-OAR-2007-0967. All documents in the docket

SUPPLEMENTARY INFORMATION: 

Background

    A complete description of the 8-hour designation process for the 
Baton Rouge area can be found in the proposal for this rulemaking at 72 
FR 61315, October 30, 2007. In addition, under Sec.  51.908 of the Code 
of Federal Regulations, states containing areas classified as 
``marginal'' non-attainment for the 8-hour ozone standard were not 
required to submit attainment demonstration SIPs. However, states were 
required to submit other SIP elements, as required by Subpart 2 of the 
Act, that included the following: submitting an emission inventory 
within two years and periodic inventories every three years thereafter, 
reasonably available control technology corrections, and retaining a 
vehicle inspection and maintenance program that may have previously 
been in place. Baton Rouge has met these requirements for a 
``marginal'' nonattainment area under the 8-hour standard and the 1-
hour standard.

I. What Does This Action Do?

    On October 30, 2007, EPA proposed its finding that the Baton Rouge 
ozone nonattainment area did not attain the 8-hour NAAQS by the 
applicable attainment date (72 FR 61315). The proposed finding was 
based upon ambient air quality data from the years 2004-2006. These 
data showed that the 8-hour NAAQS of 0.08 ppm (i.e., 0.084 ppm when 
rounding is considered) had been exceeded based on the 3-year average 
of the annual fourth highest daily maximum 8-hour average ambient air 
quality ozone concentration and that the area did not qualify for an 
attainment date extension under section 181(a)(5) of the Act. We also 
proposed to determine that the appropriate reclassification of the area 
was to ``moderate.''
    This action finalizes our finding that the Baton Rouge area did not 
attain the 8-hour ozone NAAQS by June 15, 2007, as prescribed in 
section 181 of the Act, and as detailed in EPA's final designations 
rule published on April 30, 2004 (69 FR 23857). It also fulfills EPA's 
duty pursuant to section 181(b)(2) of the Act. In addition, this action 
sets the dates by which Louisiana must submit SIP revisions addressing 
the CAA's pollution control requirements for ``moderate'' ozone 
nonattainment areas and attain the 8-hour NAAQS for ozone. EPA's 
rulemaking actions are to be effective [30] days from publication in 
the Federal Register.

II. What Does the CAA Say About Determination of Nonattainment and 
Reclassification, and How Does it Apply to the Baton Rouge Area?

    Under sections 107(d)(1)(c) and 181(a) of the Act, the Baton Rouge 
area was designated nonattainment for the 8-hour ozone NAAQS and 
classified as ``marginal'' based on its design value of 0.086 ppm in 
2004. These nonattainment designations and classifications are codified 
in 40 CFR Part 81 (See 69 FR 23857, April 30, 2004). In addition, 
states containing areas that were classified as ``marginal'' 
nonattainment were required to submit SIPs to provide for certain 
controls and submit emission inventories. The Baton Rouge area met 
these requirements by submitting an updated emission inventory. As a 
``severe'' nonattainment area under the 1-hour standard, the area was 
already implementing ``marginal'' area requirements in Subpart 2 of the 
Act. No attainment demonstrations were required, but attainment of the 
standard was required to be achieved by June 15, 2007.
    Section 181(b)(2)(A) of the Act specifies that:
    Within 6 months following the applicable attainment date (including 
any extension thereof) for an ozone nonattainment area, the 
Administrator shall determine, based on the area's design value (as of 
the attainment date), whether the area attained the standard by that 
date. Except for any Severe or Extreme areas, any area that the 
Administrator finds has not attained the standard by that date shall be 
reclassified by operation of law in accordance with table 1 of 
subsection (a) to the higher of--
    a. The next higher classification for the area, or
    b. The classification applicable to the area's design value as 
determined at the time of the notice required under subparagraph (B).
    No area shall be reclassified as Extreme under clause (ii).
    Furthermore, section 181(b)(2)(B) of the Act provides that:
    The Administrator shall publish a notice in the Federal Register no 
later than 6 months following the attainment date, identifying each 
area that the Administrator has determined under subparagraph (A) as 
having failed to attain and identifying the reclassification, if any, 
described under subparagraph (A).
    On October 30, 2007, EPA proposed its finding that the Baton Rouge 
area did not attain the 8-hour ozone standard by the applicable date 
(72 FR 61315). The proposed finding was based upon ambient ozone 
concentration data for the period 2004-2006, from monitoring sites in 
the Baton Rouge area that recorded a 3-year average of the annual 
fourth highest daily maximum 8-hour average ambient air quality ozone 
concentration that exceeded the standard. You may refer to the proposal 
to review these values which are presented in ``Table 1.--Baton Rouge 
Area Fourth Highest 8-Hour Ozone Concentrations and Design Values 
(ppm).''
    The air quality data in Table 1 were available for comment in our 
October 30, 2007, proposed finding of the area's failure to attain the 
ozone NAAQS. We

[[Page 15089]]

received no comments pertaining to these data. Therefore, pursuant to 
section 181(b)(2)(B) of the CAA, we hereby finalize our determination 
that the Baton Rouge area did not attain the 8-hour standard by the 
June 15, 2007, attainment date.

III. What Is The Area's New Classification?

    Section 181(b)(2)(A) of the Act requires that, when an area is 
reclassified for failure to attain, its reclassification be the higher 
of either the next higher classification or the classification 
applicable to the area's ozone design value at the time the notice of 
reclassification is published in the Federal Register. Section 
181(b)(2)(B) requires EPA to publish in the Federal Register a notice 
identifying the appropriate reclassification for the area in accordance 
with section 181(b)(2)(A). The classification that would be applicable 
to the Baton Rouge area's design value at the time of today's final 
rule is ``marginal'' because the area's 2006 calculated design value, 
based on quality-assured ozone monitoring data from 2004-2006, is 0.091 
ppm. By contrast, the next higher classification for the Baton Rouge 
area is ``moderate.'' As EPA explained in the proposal, because 
``moderate'' is a higher classification than ``marginal'' under the CAA 
statutory scheme, upon the effective date of this final rulemaking, the 
Baton Rouge area is reclassified by operation of law as ``moderate.''

IV. What is the New Attainment Date for the Baton Rouge Area?

    Under section 181(a)(1) of the Act, the new attainment deadline for 
``marginal'' ozone nonattainment areas, reclassified to ``moderate'' 
under section 181(b)(2), would generally be as ``expeditious as 
practicable'' but no later than the date applicable to the new 
classification, i.e., June 15, 2010. The ``as expeditiously as 
practicable'' attainment date will be determined as part of the action 
on the required SIP submittal demonstrating attainment of the 8-hour 
ozone standard.

V. When Must Louisiana Submit SIP Revisions Fulfilling the Requirements 
for 8-Hour Ozone Nonattainment Areas?

    Under section 181(a)(1) of the Act, the attainment deadline for 
``marginal'' ozone nonattainment areas reclassified to ``moderate'' 
under section 181(b)(2) is as ``expeditiously as practicable'' but no 
later than June 15, 2010. Under section 182(i) of the Act, such areas 
are required to submit SIP revisions addressing the ``moderate'' area 
requirements for 8-hour ozone NAAQS. Pursuant to 40 CFR 51.908(d), for 
each nonattainment area, a state must provide for the implementation of 
all control measures needed for attainment no later than the beginning 
of the attainment year ozone season. The attainment year ozone season 
is the ozone season immediately preceding a nonattainment area's 
attainment date, in this case 2009 (40 CFR 51.900(g)). The ozone season 
is the ozone monitoring season defined in 40 CFR Part 58, Appendix D, 
section 4.1, Table D-3 (71 FR 61236, October 17, 2006). For the purpose 
of reclassification of the Baton Rouge nonattainment area, January 1, 
2009, is the beginning of the ozone monitoring season. As a result, EPA 
is requiring that the required SIP revisions be submitted by Louisiana 
as ``expeditiously as practicable,'' but no later than January 1, 2009. 
This timeline also calls for implementation of applicable controls no 
later than January 1, 2009. (See 72 FR 61318).
    The area was previously required to submit the requirements for 
``marginal'' areas and under section 182(b) of the Act, remains 
required to meet them, and now must meet the requirements for 
``moderate'' areas as well.
    A revised SIP must include, among other things, the following 
``moderate'' area requirements: (1) An attainment demonstration (40 CFR 
51.908), (2) provisions for reasonably available control technology and 
reasonably available control measures (40 CFR 51.912), (3) reasonable 
further progress reductions in volatile organic compound (VOC) and 
nitrogen oxide (NOX) emissions (40 CFR 51.910), (4) 
contingency measures to be implemented in the event of failure to meet 
a milestone or attain the standard (CAA 172(c)(9)). See also the 
requirements for ``moderate'' ozone nonattainment areas set forth in 
CAA section 182(b). Since the Baton Rouge area also is a 1-hour ozone 
nonattainment area, the anti-backsliding requirements of the 8-hour 
ozone implementation rule at 40 CFR 51.900 and 51.905 apply too. See 
also S. Coast Air Quality Management District v. Environmental 
Protection Agency, 472 F.3d 882 (DC Cir. 2006), reh'g denied, 489 F.3d 
1245 (DC Cir. 2007).

VI. What Comments Were Received on the Proposed Rule?

    EPA received no comments from the public on the Notice of Proposed 
Rulemaking published on October 30, 2007 (72 FR 61315), Determination 
of Nonattainment and Reclassification of the Baton Rouge 8-Hour Ozone 
Nonattainment Area; State of Louisiana.

VII. Final Action

    Pursuant to CAA section 181(b)(2), EPA is making a final 
determination that the Baton Rouge ``marginal'' 8-hour ozone 
nonattainment area failed to attain the 8-hour ozone NAAQS by June 15, 
2007. Upon the effective date of this rule, the Baton Rouge 
``marginal'' 8-hour ozone nonattainment area will be reclassified by 
operation of law as a ``moderate'' 8-hour ozone nonattainment area. 
Pursuant to section 182(i) of the CAA, EPA is establishing the schedule 
for submittal of the SIP revisions required for ``moderate'' areas once 
the area is reclassified. The required SIP revision for Baton Rouge 
must be submitted as ``expeditiously as practicable,'' but no later 
than January 1, 2009.

VIII. Administrative Requirements

A. Executive Order 12866, Regulatory Planning and 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 the Executive Order. The Agency 
has determined that the finding of nonattainment would result in none 
of the effects identified in the Executive Order. Under section 
181(b)(2) of the CAA, determinations of nonattainment are based upon 
air quality considerations and the resulting reclassifications must 
occur by operation of law.

B. Paperwork Reduction Act

    This rule does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. 
This action to reclassify the Baton Rouge area as a ``moderate'' ozone 
nonattainment area and to adjust applicable deadlines does not 
establish any new information collection burden. Burden means the total 
time, effort, or financial resources expended by persons to generate, 
maintain, retain, or disclose or provide information to or for a 
Federal agency. This includes the time needed to review instructions; 
develop, acquire, install, and utilize technology and systems for the 
purposes of collecting, validating, and verifying information, 
processing and maintaining information, and disclosing and providing 
information; adjust the existing ways to comply with any previously 
applicable instructions and requirements; train personnel to be able to 
respond to a collection of information; search data sources;

[[Page 15090]]

complete and review the collection of information; and transmit or 
otherwise disclose the information. An agency may not conduct or 
sponsor, and a person is not required to respond to a collection of 
information unless it displays a currently valid Office of Management 
and Budget (OMB) control number. The OMB control numbers for EPA's 
regulations in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to prepare a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements under the Administrative 
Procedures Act or any other statute unless the agency certifies the 
rule will not have a significant economic impact on a substantial 
number of small entities. Small entities include small businesses, 
small organizations, and small governmental jurisdictions.
    For purposes of assessing the impacts of this action on small 
entities, small entity is defined as: (1) A small business that is a 
small industrial entity as defined in the U.S. Small Business 
Administration (SBA) size standards (see, 13 CFR part 121); (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. Determinations of nonattainment and the 
resulting reclassification of nonattainment areas by operation of law 
under section 181(b)(2) of the CAA do not in and of themselves create 
any new requirements. Instead, this rulemaking only makes a factual 
determination, and does not directly regulate any entities. After 
considering the economic impacts of today's action on small entities, I 
certify that this rule will not have a significant economic impact on a 
substantial number of small entities.

D. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 
Law 104-4, establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and Tribal 
governments and the private sector. Under section 202 of the UMRA, EPA 
generally must prepare a written statement, including a cost-benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures to State, local, and Tribal governments, in 
the aggregate, or to the private sector, of $100 million or more in any 
one year. Before promulgating an EPA rule for which a written statement 
is needed, sections 205 of the UMRA generally requires EPA to identify 
and consider a reasonable number of regulatory alternatives and adopt 
the least costly, most cost-effective or least burdensome alternative 
that achieves the objectives of the rule. The provisions of section 205 
do not apply when they are inconsistent with applicable law. Moreover, 
section 205 allows EPA to adopt an alternative other than the least 
costly, most cost-effective or least burdensome alternative if the 
Administrator publishes with the final rule an explanation to why that 
alternative was not adopted. Before EPA establishes any regulatory 
requirements that may significantly or uniquely affect small 
governments, including Tribal governments, it must have developed under 
section 203 of the UMRA a small government agency plan. The plan must 
provide for notifying potentially affected small governments, enabling 
officials of affected small governments to have meaningful and timely 
input in the development of EPA regulatory proposals with significant 
Federal intergovernmental mandates, and informing, educating, and 
advising small governments on compliance with the regulatory 
requirements.
    This action does not include a Federal mandate within the meaning 
of UMRA that may result in expenditures of $100 million or more in any 
one year by either State, local, or Tribal governments in the aggregate 
or to the private sector, and therefore, is not subject to the 
requirements of sections 202 and 205 of the UMRA. Also, EPA has 
determined that this rule contains no regulatory requirements that 
might significantly or uniquely affect small governments and therefore, 
is not subject to the requirements of sections 203. EPA believes, as 
discussed previously in this document, that the finding of 
nonattainment is a factual determination based upon air quality 
considerations and that the resulting reclassification of the area must 
occur by operation of law. Thus, EPA believes that the finding does not 
constitute a Federal mandate, as defined in section 101 of the UMRA, 
because it does not impose an enforceable duty on any entity.

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 final rule 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, this action merely determines 
that the Baton Rouge area had not attained by its applicable attainment 
date, and to reclassify the Baton Rouge area as a ``moderate'' ozone 
nonattainment area and to adjust applicable deadlines. Thus, Executive 
Order 13132 does not apply to this rule.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175, entitled ``A Consultation and Coordination 
With Indian Tribal Governments'' (65 FR 67249, November 9, 2000), 
requires EPA to develop an accountable process to ensure a meaningful 
and timely input by tribal officials in the development of regulatory 
policies that have tribal implications. This action does not have 
Tribal implications as specified in Executive Order 13175. This action 
merely determines that the Baton Rouge area has not attained by its 
applicable attainment date, and to reclassify the Baton Rouge area as a 
``moderate'' ozone nonattainment area and to adjust applicable 
deadlines. The CAA and the Tribal Authority Rule establish the 
relationship of the Federal government and Tribes in developing plans 
to attain the NAAQS, and this rule does nothing to modify that 
relationship. Thus, Executive Order 13175 does not apply to this rule.

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

    Executive Order 13045: ``Protection of Children From Environmental 
Health and Safety Risks'' (62 FR 19885, April 23, 1997) applies to any 
rule that (1) is determined to be ``economically significant'' as 
defined under Executive Order 12866, and (2) concerns an environmental 
health or safety risk that EPA has reason to believe may have 
disproportionate effect on children. If

[[Page 15091]]

the regulatory action meets both criteria, the Agency must evaluate the 
environmental health or safety effects of the planned rule on children, 
and explain why the planned regulation is preferable to other 
potentially effective and reasonably feasible alternatives considered 
by the Agency. This action is not subject to Executive Order 13045 
because it is not economically significant as defined in E.O. 12866, 
and because the Agency does not have reason to believe the 
environmental health risks or safety risks addressed by this rule 
present a disproportionate risk to children. This action merely 
determines that the Baton Rouge area has not attained by its applicable 
attainment date, and to reclassify the Baton Rouge area as a 
``moderate'' ozone nonattainment area and to adjust applicable 
deadlines.

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

    This action is not subject to Executive Order 13211, ``Actions That 
Significantly Affect Energy Supply, Distribution, or Use,'' (66 FR 
28355, May 22, 2001) because it is not a significant regulatory action 
under Executive Order 12866.

I. National Technology Transfer Advancement Act

    As noted in the proposed rule, Section 12(d) of the National 
Technology Transfer 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 (VCS) 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 VCS bodies. The NTTAA 
directs EPA to provide Congress, through OMB, explanations when the 
Agency decides not to use available and applicable VCS. This action 
merely determines that the Baton Rouge area has not attained by its 
applicable attainment date, and to reclassify the Baton Rouge 
``marginal'' Nonattainment Area as a ``moderate'' ozone nonattainment 
area and to adjust applicable deadlines. Therefore, EPA did not 
consider the use of any voluntary consensus standards.

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 has determined that this rule will not have disproportionately 
high and adverse human health or environmental effects on minority or 
low-income populations because it does not affect the level of 
protection provided to human health or the environment. This action 
merely determines that the Baton Rouge area has not attained by its 
applicable attainment date, and to reclassify the Baton Rouge area as a 
``moderate'' ozone nonattainment area and to adjust applicable 
deadlines.

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 rule 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. This rule is not a 
``major rule'' as defined by 5 U.S.C. 804(2).

L. Petitions for 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 May 20, 2008. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this rule 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 to reclassify the Baton Rouge area as a 
``moderate'' ozone nonattainment area and to adjust applicable 
deadlines may not be challenged later in proceedings to enforce its 
requirements. (See section 307(b)(2)).
