Air Plan Approval; North Carolina; Revision to Approved Motor
Vehicle Emissions Budgets
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is approving a
revision to the North Carolina State Implementation Plan (SIP),
submitted on July 16, 2020, by the State of North Carolina, through the
North Carolina Department of Environment and Natural Resources,
Division of Air Quality (NCDAQ) for the purpose of allocating a portion
of the available 2026 safety margin in the 2008 8-hour Ozone
Maintenance Plan to the 2026 nitrogen oxides (NOX) and
volatile organic compounds (VOC) motor vehicle emissions budgets
(``MVEBs'' or ``budgets'') for the North Carolina portion of the
Charlotte-Rock Hill, NC-SC bi-state Area (hereinafter referred to as
the ``North Carolina portion of the Charlotte Maintenance Area'') to
account for uncertainty associated with the mobile emissions model and
unanticipated growth in vehicle miles traveled for the North Carolina
portion of the Charlotte Maintenance Area. The revision also updates
the 2026 MVEBs which are used for transportation conformity. NCDAQ's
July 16, 2020, submission supplements the revised 2008 8-hour Ozone
Maintenance Plan submitted by NCDAQ on July 25, 2018, and approved by
EPA on September 11, 2019. EPA is approving North Carolina's July 16,
2020, supplemental SIP revision pursuant to the Clean Air Act (CAA or
Act) and deeming the MVEBs adequate for transportation conformity
purposes because the SIP meets all the statutory and regulatory
requirements.
DATES: This rule is effective September 24, 2021.

SUPPLEMENTARY INFORMATION:
I. This Action
EPA is approving NCDAQ's July 16, 2020, SIP revision allocating a
portion of the available safety margin to revise the 2026
NOX and VOC budgets for the North Carolina portion of
Charlotte 2008 8-hour Ozone Maintenance Area for transportation
conformity purposes. NCDAQ requested approval of the July 16, 2020, SIP
revision in order to account for unanticipated changes in the travel
demand model, such as unanticipated growth in vehicle miles traveled,
changes and uncertainty in vehicle mix assumptions, and uncertainty
associated with mobile emissions modeling.
Upon approval, the revised 2026 budgets from NCDAQ's July 16, 2020,
SIP revision will replace the existing budgets in the State's 2008 8-
hour Ozone Maintenance Plan revision approved on September 11, 2019.
See 84 FR 47889. These newly revised NOX and VOC 2026
budgets must be used in future transportation conformity analyses for
the Area according to the transportation conformity rule. See 40 CFR
93.118. Also, all emissions inventories (on-road, point, area, and
nonroad) from NCDAQ's September 11, 2019, SIP revision remain the same.
This action only approves the allocation of a portion of the available
safety margin to the 2026 NOX and VOC MVEBs. EPA is
approving North Carolina's July 16, 2020, SIP revision because it
continues to demonstrate maintenance for the Charlotte Maintenance
Area.
II. Background
Effective July 20, 2012, EPA designated the Charlotte-Rock Hill,
NC-SC Area as Marginal nonattainment for the 2008 8-hour ozone national
ambient air quality standard (hereinafter referred to as NAAQS or
standard). The North Carolina portion of the Charlotte 2008 Maintenance
Area includes Mecklenburg in its entirety and portions of Cabarrus,
Gaston, Iredell, Lincoln, Rowan, and Union counties. The Charlotte
Maintenance Area also includes a portion of York County located in Rock
Hill, South Carolina. See 77 FR 30088. The North Carolina portion of
the Charlotte Maintenance Area is comprised of three metropolitan
planning organizations (MPOs): The Charlotte Regional Transportation
Planning Organization (CRTPO) which covers Iredell, Mecklenburg, and
Union counties; the Cabarrus-Rowan Metropolitan Planning Organization
(CRMPO) which covers Cabarrus and Rowan counties; and the Gaston-
Cleveland-Lincoln Metropolitan
[[Page 47388]]
Planning Organization (GCLMPO) which covers Gaston, Cleveland, and
Lincoln counties. Although Cleveland County is included in the GCLMPO
planning boundary, it was not included in the North Carolina portion of
the Charlotte Maintenance Area. Each MPO has its own budget referred to
as a ``sub-area budget or sub-area MVEBs.'' The York County, South
Carolina portion of this maintenance area has a separate MPO and
budgets. The South Carolina portion of the maintenance area implements
transportation conformity independent of the North Carolina portion.
EPA originally approved NCDAQ's 2008 8-hour ozone redesignation
request and maintenance SIP for the North Carolina portion of the
Charlotte Maintenance Area on July 28, 2015 (80 FR 44873), with base
year NOX and VOC actual emissions inventories for 2014;
projected, future, interim year inventories for 2015, 2018, and 2022;
and projected final year emission inventory for 2026. On August 17,
2015 (80 FR 49164), EPA approved North Carolina's section 110(l)
noninterference demonstration requesting relaxation of the Federal Reid
Vapor Pressure from 7.8 pounds per square inch (psi) to 9.0 psi and a
revision to the 2026 NOX and VOC sub-area MVEBs for
Mecklenburg and Gaston Counties only. See 80 FR 44868.
On September 11, 2019 (84 FR 47889), EPA approved NCDAQ's July 25,
2018, SIP revision related to North Carolina's I/M Program. The
September 11, 2019, SIP approval updated the on-road mobile source
inventory and revised the 2026 sub-area VOC and NOX budgets;
these remain the current SIP-approved MVEBs and inventories. The
revised 2026 MVEBs became effective on October 11, 2019.
EPA's analysis of North Carolina's July 16, 2020, SIP submittal
indicates that maintenance will continue to be demonstrated for the
Charlotte Maintenance Area after allocation of a portion of the safety
margin to the 2026 MVEBs because the total level of emissions from all
source categories remains equal to or less than the attainment level of
emissions.
In a notice of proposed rulemaking (NPRM), published in the Federal
Register on June 23, 2021 (86 FR 32850), EPA proposed to approve the
July 16, 2020, SIP revision. The details of North Carolina's submittal
and the rationale for EPA's action are further explained in the NPRM.
Comments on the June 23, 2021, NPRM were due on or before July 23,
2021. EPA did not receive any comments.
Tables 1 through 3, below, provide the newly revised 2026
NOX and VOC sub-area MVEBs with the new safety margin \1\
allocations in kilograms per day (kg/day) for transportation conformity
purposes (2014 is only shown for illustration because no changes are
being made to the MVEBs for that year).
---------------------------------------------------------------------------
\1\ A safety margin is the difference between the attainment
level of emissions from all source categories (i.e., point, area,
on-road, and nonroad) and the projected level of emissions in the
maintenance year from all source categories.

III. Final Action
EPA has evaluated North Carolina's submittal and has determined
that it meets the applicable requirements of the CAA and EPA
regulations, and is consistent with EPA policy.
Therefore, EPA is approving NCDAQ's July 16, 2020 SIP revision
requesting to revise the Charlotte 2008 8-hr Ozone Maintenance Plan in
order to allocate a portion of the available safety margin to the 2026
NOX and VOC MVEBs. The revised MVEBs ensure continued
attainment of the 2008 8-hour ozone NAAQS through the maintenance year
2026. In addition, EPA is deeming the MVEBs adequate for transportation
conformity purposes because the budgets meet the adequacy criteria in
the conformity rule at 40 CFR 93.118(e)(4). Within 24 months from the
effective date of this approval, the transportation partners are
required to demonstrate conformity to the revised NOX and
VOC MVEBs pursuant to 40 CFR 93.104(e).
IV. 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. See 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 they meet the criteria of the CAA. 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 Orders 12866 (58
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
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 CAA; 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). The SIP is not
approved to apply on any Indian reservation land or in any other area
where EPA or an Indian tribe has demonstrated that a tribe has
jurisdiction. In those areas of Indian country, the rule does not have
tribal implications as specified by Executive Order 13175 (65 FR 67249,
November 9, 2000), nor will it 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 October 25, 2021. 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).
