[EPA-R04-OAR-2013-0129; FRL-9903-37-Region-4]

Approval and Promulgation of Implementation Plans and Designation 
of Areas for Air Quality Planning Purposes; North Carolina; 
Redesignation of the Charlotte; 1997 8-Hour Ozone Moderate 
Nonattainment Area to Attainment

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is taking final action to redesignate the portion of North 
Carolina that is within the bi-state Charlotte-Gastonia-Rock Hill, 
North Carolina-South Carolina 8-hour ozone nonattainment area 
(hereafter referred to as the ``Area,'' ``North Carolina portion of the 
bi-state Charlotte Area,'' ``North Carolina portion of the Area,'' or 
``Metrolina nonattainment area'') to attainment for the 1997 8-hour 
ozone national ambient air quality standards (NAAQS), and to approve 
the maintenance plan for the Area. The State of North Carolina, through 
the North Carolina Department of Environment and Natural Resources, 
Department of Air Quality (NC DAQ), submitted the redesignation request 
and maintenance plan on November 2, 2011. The State supplemented the 
redesignation request and maintenance plan on March 28, 2013, extending 
the maintenance plan to the year 2025 and updating the sub-area motor 
vehicle emission budgets (MVEBs) for nitrogen oxides (NOX) 
and volatile organic compounds (VOC) for the years 2013 and 2025 for 
the North Carolina portion of the Area. EPA's approval of NC DAQ's 
redesignation request is based on the determination that North Carolina 
has met the criteria for redesignation to attainment set forth in the 
Clean Air Act (CAA or Act). EPA finalized action to redesignate the 
South Carolina portion of the Area, including approval of South 
Carolina's maintenance plan for the 1997 8-hour ozone NAAQS, in a 
separate action.

DATES: This rule will be effective on January 2, 2014.

I. What is the background for the actions?

    On November 2, 2011, North Carolina requested redesignation of the 
North Carolina portion of the bi-state Charlotte Area to attainment for 
the 1997 8-hour ozone NAAQS. The bi-state Charlotte Area consists of 
Cabarrus, Gaston, Lincoln, Mecklenburg, Rowan, Union, and a portion of 
Iredell County (Davidson and Coddle Creek Townships), North Carolina; 
and a portion of York County, South Carolina. The redesignation request 
included three years of complete, quality-assured ambient air quality 
data for the 1997 8-hour ozone NAAQS for 2008-2010, indicating that the 
1997 8-hour ozone NAAQS had been achieved for the Area. Under the CAA, 
nonattainment areas may be redesignated to attainment if sufficient, 
complete, quality-assured data is available for the Administrator to 
determine that the area has attained the standard and the area meets 
the other CAA redesignation requirements in section 107(d)(3)(E).
    Subsequently, on November 15, 2011 (76 FR 70656), EPA determined 
that the bi-state Charlotte Area attained the 1997 8-hour ozone NAAQS. 
The determination of attaining data was based upon complete, quality-
assured and certified ambient air monitoring data for the 2008-2010 
period, showing that the Area had monitored attainment of the 1997 8-
hour ozone NAAQS.
    On March 28, 2013, North Carolina submitted a supplemental SIP 
revision to the redesignation request and maintenance plan that extends 
the final year of the maintenance plan to 2025. Specifically, this 
revision updates emissions data, emissions projections, MVEBs, and 
safety margins to 2025. Additionally, it provides updated ozone design 
values for the bi-state Charlotte Area.
    EPA reviewed quality-assured ozone monitoring data from ambient 
ozone monitoring stations in the Charlotte Area, as recorded in Air 
Quality System (AQS), and summarized the 3-year average of the annual 
fourth highest daily maximum 8-hour average (i.e., design value) for 
each monitor for 2008-2010, 2009-2011, and 2010-2012 in Tables 1, 2, 
and 3 below. The 2008-2010 design values demonstrate that the Area 
attained by its attainment date, and the 2009-2011 and 2010-2012 design 
values demonstrate that the bi-state Charlotte Area continues to meet 
the 1997 8-hour ozone NAAQS. Preliminary data indicate that the Area 
continues to attain with 2011-2013 data.

*An ozone monitor is located in York County, SC; however, it is outside of the nonattainment area. This monitor is monitoring attainment of the 1997 8-
  hour ozone NAAQS.

    This rulemaking does not address requirements for the bi-state 
Charlotte Area that was designated nonattainment for the 2008 8-hour 
ozone NAAQS. Requirements for the bi-state Charlotte 2008 8-hour ozone 
nonattainment area will be addressed in the future.
    NC DAQ chose to establish sub-area MVEBs based on geographical 
areas that correspond to the Metropolitan Planning Organization (MPO) 
and/or Rural Planning Organization (RPO) boundaries. Accordingly, NC 
DAQ established MVEBs for the CRMPO (Cabarrus and Rowan Counties), for 
the Gaston Urban Area MPO and Lake Norman RPO (Gaston, Iredell, and 
Lincoln Counties), and for the MUMPO and Rocky River RPO (Mecklenburg 
and Union Counties) geographical areas.

II. What are the actions EPA is taking?

    In today's rulemaking, EPA is approving: (1) North Carolina's 1997 
8-hour ozone maintenance plan as amended by the State's March 28, 2013 
supplemental SIP submittal (such approval being one of the CAA criteria 
for redesignation to attainment) for the North Carolina portion of the 
Area, including the sub-area MVEBs; and (2)

[[Page 72038]]

North Carolina's redesignation request to change the legal designation 
of the North Carolina portion of the Area from nonattainment to 
attainment for the 1997 8-hour ozone NAAQS. The maintenance plan meets 
the requirements of section 175A and is designed to demonstrate that 
the North Carolina portion of the Area (as part of the bi-state 
Charlotte Area) will continue to attain the 1997 8-hour ozone NAAQS 
through 2025. EPA's approval of the redesignation request is based on 
EPA's determination that North Carolina meets the criteria for the 
North Carolina portion of the Area for redesignation set forth in CAA 
section 107(d)(3)(E), including EPA's determination that the North 
Carolina portion of the Area has attained the 1997 8-hour ozone NAAQS. 
EPA's analyses of North Carolina's redesignation request and 
maintenance plan are described in detail in the July 26, 2013, proposed 
rule. See 78 FR 45152. EPA did not receive any comments, adverse or 
otherwise, on the July 26, 2013, proposed rule to redesignate the North 
Carolina portion of the bi-state Charlotte Area to attainment for the 
1997 8-hour ozone NAAQS. EPA finalized the adequacy determination for 
the MVEBs on August 13, 2013. See 78 FR 49265. EPA finalized approval 
of South Carolina's request to redesignate the South Carolina portion 
of the Area, including approval of South Carolina's maintenance plan 
for the 1997 8-hour ozone NAAQS, in a separate action. See 77 FR 75862.
    Consistent with the CAA, the maintenance plan that EPA is approving 
also includes 2013 and 2025 sub-area MVEBs for NOX and VOC 
for the North Carolina portion of the Area. EPA informed the public 
that the 2013 and 2025 sub-area MVEBs are adequate for transportation 
conformity on August 13, 2013. See 78 FR 49265. Tables 4 through 6 
below provide the NOX and VOC sub-area MVEBs in kilograms 
per day (kg/day),\1\ for 2013 and 2025.
---------------------------------------------------------------------------

    \1\ The conversion to kilograms used the actual emissions 
reported in the MOVES model. The conversion was done utilizing the 
``CONVERT'' function in an EXCEL spreadsheet.

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

    North Carolina has chosen to allocate a portion of the available 
safety margin to the NOX and VOC MVEBs for 2013 and 2025 
(45.20 tpd and 107.38 tpd of the NOX 2013 and 2025 safety 
margins remain, respectively, and 19.96 tpd and 27.95 tpd of the VOC 
2013 and 2025 safety margins remain, respectively).
    In this action, EPA is also approving these NOX and VOC 
sub-area MVEBs for the purposes of transportation conformity. For 
required regional emissions analysis years involving 2013 and prior to 
2025, the applicable budgets will be the new 2013 sub-area MVEBs. For 
required regional emissions analysis years that involve 2025 or beyond, 
the applicable budgets will be the new 2025 sub-area MVEBs.

III. Why is EPA taking these actions?

    EPA has determined that the North Carolina portion of the Area has 
attained the 1997 8-hour ozone NAAQS and has also determined that all 
other criteria for the redesignation of the North Carolina portion of 
the Area from nonattainment to attainment of the 1997 8-hour ozone 
NAAQS have been met. See CAA section 107(d)(3)(E). One of those 
requirements is that the North Carolina portion of the Area has an 
approved plan demonstrating maintenance of the 1997 8-hour ozone NAAQS. 
EPA is taking final action to approve the maintenance plan for the 
North Carolina portion of the Area as meeting the requirements of 
sections 175A and 107(d)(3)(E) of the CAA. EPA is also approving the 
new NOX and VOC sub-area MVEBs for the years 2013 and 2025 
as contained in North Carolina's maintenance plan for the North 
Carolina portion of the Area because these sub-area MVEBs are 
consistent with maintenance of the 1997 8-hour ozone NAAQS in the Area. 
The detailed rationale for EPA's findings and actions are set forth in 
the July 26, 2013, proposed rulemaking and in other discussion in this 
final rulemaking.

IV. What are the effects of these actions?

    Approval of the redesignation request changes the legal designation 
of the North Carolina portion of the Area from nonattainment to 
attainment for the 1997 8-hour ozone NAAQS. EPA is modifying the 
regulatory table in 40 CFR 81.334 to reflect a designation of 
attainment for the affected counties. EPA is also approving, as a 
revision to the North Carolina SIP, the State's plan for maintaining 
the 1997 8-hour ozone NAAQS in the North Carolina portion of the Area 
through 2025. The maintenance plan includes contingency measures to 
remedy possible future violations of the 1997 8-hour ozone NAAQS, and 
establishes NOX and VOC subarea MVEBs for the years 2013 and 
2025 for the North Carolina portion of the Area.

V. Final Action

    EPA is taking final action to approve the redesignation and change 
the legal designation of the North Carolina portion of the Area from 
nonattainment

[[Page 72039]]

to attainment for the 1997 8-hour ozone NAAQS. Through this action, EPA 
is also approving into the North Carolina SIP the 1997 8-hour ozone 
maintenance plan for the North Carolina portion of the Area, which 
includes the new NOX and VOC sub-area MVEBs for 2013 and 
2025 for the North Carolina portion of the Area.

VI. Statutory and Executive Order Reviews

    Under the CAA, redesignation of an area to attainment and the 
accompanying approval of the maintenance plan under CAA section 
107(d)(3)(E) are actions that affect the status of geographical area 
and do not impose any additional regulatory requirements on sources 
beyond those required by state law. A redesignation to attainment does 
not in and of itself impose any new requirements, but rather results in 
the application of requirements contained in the CAA for areas that 
have been redesignated to attainment. Moreover, 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 CAA. 
Accordingly, these actions merely approve state law as meeting Federal 
requirements and do not impose additional requirements beyond those 
imposed by state or federal law. For these reasons, these actions:
     Are 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);
     do not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     are 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.);
     do not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Public Law 104-4);
     do not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     are not an economically significant regulatory action 
based on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     are not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     are 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 CAA; and,
     do 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 CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by January 31, 2014. 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).
