I. What are the actions EPA is proposing to take?

    EPA is proposing to take the following three separate but related 
actions, one of which involves multiple elements: (1) To determine that 
the bi-Charlotte Area is attaining the 2008 8-hour ozone NAAQS; (2) to 
approve North Carolina's plan for maintaining the 2008 8-hour ozone 
NAAQS (maintenance plan), including the associated sub-area MVEBs for 
the North Carolina portion of the bi-state Charlotte Area, into the 
SIP; and (3) to redesignate the North Carolina portion of the bi-state 
Charlotte Area to attainment for the 2008 8-hour ozone NAAQS. EPA is 
also notifying the public of the status of EPA's adequacy determination 
for the sub-area MVEBs for the North Carolina portion of the bi-state 
Charlotte Area. The bi-state Charlotte Area consists of Mecklenburg 
County in its entirety and portions of Cabarrus, Gaston, Iredell, 
Lincoln, Rowan and Union Counties, North Carolina; and a portion of 
York County, South Carolina. On April 17, 2015, the State of South 
Carolina, through the South Carolina Department of Health and Control 
(SC DHEC), provided a redesignation request and maintenance plan for 
its portion of the bi-state Charlotte Area. EPA will address South 
Carolina's request and maintenance plan in a separate action. These 
proposed actions are summarized below and described in greater detail 
throughout this notice of proposed rulemaking.
    EPA is also making the preliminarily determination that the bi-
state Charlotte Area is attaining the 2008 8-hour ozone NAAQS based on 
recent air quality data and proposing to approve North Carolina's 
maintenance plan for its portion of the bi-state Charlotte Area as 
meeting the requirements of section 175A (such approval being one of 
the CAA criteria for redesignation to attainment status). The 
maintenance plan is designed to keep the bi-state Charlotte Area in 
attainment of the 2008 8-hour ozone NAAQS through 2026. The maintenance 
plan includes 2014 and 2026 sub-area MVEBs for NOX and VOC 
for the North Carolina portion of the bi-state Charlotte Area for 
transportation conformity purposes. EPA is proposing to approve these 
sub-area MVEBs and incorporate them into the North Carolina SIP.
    EPA also proposes to determine that the North Carolina portion of 
the bi-state Charlotte Area has met the requirements for redesignation 
under section 107(d)(3)(E) of the CAA. Accordingly, in this action, EPA 
is proposing to approve a request to change the legal designation of 
Mecklenburg County in its entirety and the following portions of:
     Cabarrus County (Central Cabarrus Township, Concord 
Township, Georgeville Township, Harrisburg Township, Kannapolis 
Township, Midland Township, Mount Pleasant Township, New Gilead 
Township, Odell Township, Poplar Tent Township, Rimertown Township),
     Gaston County (Crowders Mountain Township, Dallas 
Township, Gastonia Township, Riverbend Township, South Point Township),
     Iredell County (Davidson Township, Coddle Creek Township),
     Lincoln County (Catawba Springs Township, Ironton 
Township, Lincolnton Township),
     Rowan County (Atwell Township, China Grove Township, 
Franklin Township, Gold Hill Township, Litaker Township, Locke 
Township, Providence Township, Salisbury Township, Steele Township, 
Unity Township), and
     Union County (Goose Creek Township, Marshville Township, 
Monroe Township, Sandy Ridge Township, Vance Township), in North 
Carolina from nonattainment to attainment for the 2008 8-hour ozone 
NAAQS.
    EPA is also notifying the public of the status of EPA's adequacy 
process for the 2014 and 2026 NOX and VOC sub-area MVEBs for 
the North Carolina portion of the bi-state Charlotte Area. The Adequacy 
comment period began on March 17, 2015, with EPA's posting of the 
availability of North Carolina's submissions on EPA's Adequacy Web site 
(http://www.epa.gov/otaq/stateresources/transconf/currsips.htm#north-carolina). The Adequacy comment period for these sub-area MVEBs closed 
on April 16, 2015. No comments, adverse or otherwise, were received 
through the Adequacy process. Please see section VII of this proposed 
rulemaking for further explanation of this process and for more details 
on the sub-area MVEBs.
    In summary, this notice of proposed rulemaking is in response to 
North Carolina's April 16, 2015, redesignation request and associated 
SIP submission that address the specific issues summarized above and 
the necessary elements described in section 107(d)(3)(E) of the CAA for 
redesignation of the North Carolina portion of the bi-state Charlotte 
Area to attainment for the 2008 8-hour ozone NAAQS.

II. What is the background for EPA's proposed actions?

    On March 12, 2008, EPA promulgated a revised 8-hour ozone NAAQS of 
0.075 parts per million (ppm). See 73 FR 16436 (March 27, 2008). Under 
EPA's regulations at 40 CFR part 50, the 2008 8-hour ozone NAAQS is 
attained when the 3-year average of the annual fourth highest daily 
maximum 8-hour average ambient air quality ozone concentrations is less 
than or equal to 0.075 ppm. See 40 CFR 50.15. Ambient air quality 
monitoring data for the 3-year period must meet a data completeness 
requirement. The ambient air quality monitoring data completeness 
requirement is met when the average percent of days with valid ambient 
monitoring data is greater than 90 percent, and no single year has less 
than 75 percent data completeness as determined in Appendix I of part 
50.
    Upon promulgation of a new or revised NAAQS, the CAA requires EPA 
to designate as nonattainment any area that is violating the NAAQS, 
based on the three most recent years of complete, quality assured, and 
certified ambient air quality data at the conclusion of the designation 
process. The bi-state Charlotte Area was designated nonattainment for 
the 2008 8-hour ozone NAAQS on May 21, 2012 (effective July 20, 2012) 
using 2009-2011 ambient air quality data. See 77 FR 30088 (May 21, 
2012). At the time of designation, the bi-state Charlotte Area was 
classified as a marginal nonattainment area for the 2008 8-hour ozone 
NAAQS. In the final implementation rule for the 2008 8-hour ozone NAAQS 
(SIP Implementation

[[Page 29252]]

Rule),\1\ EPA established ozone nonattainment area attainment dates 
based on Table 1 of section 181(a) of the CAA. This established an 
attainment date three years after the July 20, 2012, effective date for 
areas classified as marginal areas for the 2008 8-hour ozone 
nonattainment designations. Therefore, the bi-state Charlotte Area's 
attainment date is July 20, 2015.
---------------------------------------------------------------------------

    \1\ This rule, entitled Implementation of the 2008 National 
Ambient Air Quality Standards for Ozone: State Implementation Plan 
Requirements and published at 80 FR 12264 (March 6, 2015), addresses 
a range of nonattainment area SIP requirements for the 2008 ozone 
NAAQS, including requirements pertaining to attainment 
demonstrations, reasonable further progress (RFP), reasonably 
available control technology (RACT), reasonably available control 
measures (RACM), major new source review (NSR), emission 
inventories, and the timing of SIP submissions and of compliance 
with emission control measures in the SIP. This rule also addresses 
the revocation of the 1997 ozone NAAQS and the anti-backsliding 
requirements that apply when the 1997 ozone NAAQS are revoked.
---------------------------------------------------------------------------

III. What are the criteria for redesignation?

    The CAA provides the requirements for redesignating a nonattainment 
area to attainment. Specifically, section 107(d)(3)(E) of the CAA 
allows for redesignation providing that: (1) The Administrator 
determines that the area has attained the applicable NAAQS; (2) the 
Administrator has fully approved the applicable implementation plan for 
the area under section 110(k); (3) the Administrator determines that 
the improvement in air quality is due to permanent and enforceable 
reductions in emissions resulting from implementation of the applicable 
SIP and applicable Federal air pollutant control regulations and other 
permanent and enforceable reductions; (4) the Administrator has fully 
approved a maintenance plan for the area as meeting the requirements of 
section 175A; and, (5) the state containing such area has met all 
requirements applicable to the area for purposes of redesignation under 
section 110 and part D of the CAA.
    On April 16, 1992, EPA provided guidance on redesignation in the 
General Preamble for the Implementation of title I of the CAA 
Amendments of 1990 (57 FR 13498), and supplemented this guidance on 
April 28, 1992 (57 FR 18070). EPA has provided further guidance on 
processing redesignation requests in the following documents:

IV. Why is EPA proposing these actions?

    On April 16, 2015, the State of North Carolina, through NC DAQ, 
requested that EPA redesignate the North Carolina portion of the bi-
state Charlotte Area to attainment for the 2008 8-hour ozone NAAQS. 
EPA's evaluation indicates that the entire bi-state Charlotte Area has 
attained the 2008 8-hour ozone NAAQS, and that the North Carolina 
portion of the bi-state Charlotte Area meets the requirements for 
redesignation as set forth in section 107(d)(3)(E), including the 
maintenance plan requirements under section 175A of the CAA. As a 
result, EPA is proposing to take the three related actions summarized 
in section I of this document.

V. What is EPA's analysis of the request?

    As stated above, in accordance with the CAA, EPA proposes in this 
action to: (1) Determine that the bi-state Charlotte Area is attaining 
the 2008 8-hour ozone NAAQS; (2) approve the North Carolina portion of 
the bi-state Charlotte Area's 2008 8-hour ozone NAAQS maintenance plan, 
including the associated sub-area MVEBs, into the North Carolina SIP; 
and (3) redesignate the North Carolina portion of the bi-state 
Charlotte Area to attainment for the 2008 8-hour ozone NAAQS. The five 
redesignation criteria provided under CAA section 107(d)(3)(E) are 
discussed in greater detail for the Area in the following paragraphs of 
this section.

Criteria (1)--The Bi-State Charlotte Area Has Attained the 2008 8-Hour 
Ozone NAAQS

    For redesignating a nonattainment area to attainment, the CAA 
requires EPA to determine that the area has attained the applicable 
NAAQS (CAA section 107(d)(3)(E)(i)). For ozone, an area may be 
considered to be attaining the 2008 8-hour ozone NAAQS if it meets the 
2008 8-hour ozone NAAQS, as determined in accordance with 40 CFR 50.15 
and Appendix I of part 50, based on three complete, consecutive 
calendar years of quality-assured air quality monitoring data. To 
attain the NAAQS, the 3-year average of the fourth-highest daily 
maximum 8-hour average ozone concentrations measured at each monitor 
within an area over each year must not exceed 0.075 ppm. Based on the 
data handling and reporting convention described in 40 CFR part 50, 
Appendix I, the NAAQS are attained if the design value is 0.075 ppm or 
below. The data must be collected and quality-assured in accordance 
with 40 CFR part 58 and recorded in the EPA Air Quality System (AQS). 
The monitors generally should have remained at the same location for 
the duration of the monitoring period required for demonstrating 
attainment.
    In this action, EPA is preliminarily determining that the bi-state 
Charlotte Area is attaining the 2008 8-hour ozone NAAQS. EPA reviewed 
ozone monitoring data from monitoring stations in the bi-state 
Charlotte Area for the 2008 8-hour ozone NAAQS for 2012-2014. These 
data have been quality-assured, are recorded in Aerometric Information 
Retrieval System (AIRS-AQS), and indicate that

[[Page 29253]]

the Area is attaining the 2008 8-hour ozone NAAQS. The fourth-highest 
8-hour ozone values at each monitor for 2012, 2013, 2014, and the 3-
year averages of these values (i.e., design values), are summarized in 
Table 1, below.

    The 3-year design value for 2012-2014 for the bi-state Charlotte 
Area is 0.073 ppm,\2\ which meets the NAAQS. In this action, EPA is 
proposing to determine that the bi-state Charlotte Area is attaining 
the 2008 8-hour ozone NAAQS. EPA will not take final action to approve 
the redesignation if the 3-year design value exceeds the NAAQS prior to 
EPA finalizing the redesignation. As discussed in more detail below, 
the State of North Carolina has committed to continue monitoring in 
this Area in accordance with 40 CFR part 58.
---------------------------------------------------------------------------

    \2\ The monitor with the highest 3-year design value is 
considered the design value for the Area.

Criteria (2)--North Carolina Has a Fully Approved SIP Under Section 
110(k) for the North Carolina Portion of the Charlotte Area; and 
Criteria (5)--North Carolina Has Met All Applicable Requirements Under 
Section 110 and Part D of Title I of the CAA

    For redesignating a nonattainment area to attainment, the CAA 
requires EPA to determine that the state has met all applicable 
requirements under section 110 and part D of title I of the CAA (CAA 
section 107(d)(3)(E)(v)) and that the state has a fully approved SIP 
under section 110(k) for the area (CAA section 107(d)(3)(E)(ii)). EPA 
proposes to find that North Carolina has met all applicable SIP 
requirements for the North Carolina portion of the Area under section 
110 of the CAA (general SIP requirements) for purposes of 
redesignation. Additionally, EPA proposes to find that the North 
Carolina SIP satisfies the criterion that it meets applicable SIP 
requirements for purposes of redesignation under part D of title I of 
the CAA in accordance with section 107(d)(3)(E)(v). Further, EPA 
proposes to determine that the SIP is fully approved with respect to 
all requirements applicable for purposes of redesignation in accordance 
with section 107(d)(3)(E)(ii). In making these determinations, EPA 
ascertained which requirements are applicable to the Area and, if 
applicable, that they are fully approved under section 110(k). SIPs 
must be fully approved only with respect to requirements that were 
applicable prior to submittal of the complete redesignation request.
a. The North Carolina Portion of the Bi-State Charlotte Area Has Met 
All Applicable Requirements Under Section 110 and Part D of the CAA
    General SIP requirements. General SIP elements and requirements are 
delineated in section 110(a)(2) of title I, part A of the CAA. These 
requirements include, but are not limited to, the following: Submittal 
of a SIP that has been adopted by the state after reasonable public 
notice and hearing; provisions for establishment and operation of 
appropriate procedures needed to monitor ambient air quality; 
implementation of a source permit program; provisions for the 
implementation of part C requirements (Prevention of Significant 
Deterioration (PSD)) and provisions for the implementation of part D 
requirements (NSR permit programs); provisions for air pollution 
modeling; and provisions for public and local agency participation in 
planning and emission control rule development.
    Section 110(a)(2)(D) requires that SIPs contain certain measures to 
prevent sources in a state from significantly contributing to air 
quality problems in another state. To implement this provision, EPA has 
required certain states to establish programs to address the interstate 
transport of air pollutants. The section 110(a)(2)(D) requirements for 
a state are not linked with a particular nonattainment area's 
designation and classification in that state. EPA believes that the 
requirements linked with a particular nonattainment area's designation 
and classifications are the relevant measures to evaluate in reviewing 
a redesignation request. The transport SIP submittal requirements, 
where applicable, continue to apply to a state regardless of the 
designation of any one particular area in the state. Thus, EPA does not 
believe that the CAA's interstate transport requirements should be 
construed to be applicable requirements for purposes of redesignation.
    In addition, EPA believes other section 110 elements that are 
neither connected with nonattainment plan submissions nor linked with 
an area's attainment status are applicable requirements for purposes of 
redesignation. The area will still be subject to these requirements 
after the area is redesignated. The section 110 and part D requirements 
which are linked with a particular area's designation and 
classification are the relevant measures to evaluate in reviewing a 
redesignation request. This approach is consistent with EPA's existing 
policy on applicability (i.e., for redesignations) of conformity and 
oxygenated fuels requirements, as well as with section 184 ozone 
transport requirements. See Reading, Pennsylvania, proposed and final 
rulemakings (61 FR 53174-53176, October 10, 1996), (62 FR 24826, May 7, 
2008); Cleveland-Akron-Loraine, Ohio, final rulemaking (61 FR 20458, 
May 7,

[[Page 29254]]

1996); and Tampa, Florida, final rulemaking at (60 FR 62748, December 
7, 1995). See also the discussion on this issue in the Cincinnati, 
Ohio, redesignation (65 FR 37890, June 19, 2000), and in the 
Pittsburgh, Pennsylvania, redesignation (66 FR 50399, October 19, 
2001).
    Title I, Part D, applicable SIP requirements. Section 172(c) of the 
CAA sets forth the basic requirements of attainment plans for 
nonattainment areas that are required to submit them pursuant to 
section 172(b). Subpart 2 of part D, which includes section 182 of the 
CAA, establishes specific requirements for ozone nonattainment areas 
depending on the area's nonattainment classification. As provided in 
Subpart 2, a marginal ozone nonattainment area, such as the bi-state 
Charlotte Area, must submit an emissions inventory that complies with 
section 172(c)(3), but the specific requirements of section 182(a) 
apply in lieu of the demonstration of attainment (and contingency 
measures) required by section 172(c). 42 U.S.C. 7511a(a). A thorough 
discussion of the requirements contained in sections 172(c) and 182 can 
be found in the General Preamble for Implementation of Title I (57 FR 
13498).
    Section 182(a) Requirements. Section 182(a)(1) requires states to 
submit a comprehensive, accurate, and current inventory of actual 
emissions from sources of VOC and NOX emitted within the 
boundaries of the ozone nonattainment area. North Carolina provided an 
emissions inventory for the bi-state Charlotte Area to EPA in a July 7, 
2014 SIP submission. On April 21, 2015, EPA published a direct final 
rule to approve this emissions inventory into the SIP.\3\ See 80 FR 
22107 (direct final rule) and 80 FR 22147 (associated proposed rule). 
North Carolina's section 182(a)(1) inventory must be incorporated into 
the SIP before EPA can take final action to approve the State's 
redesignation request for the bi-state Charlotte Area.
---------------------------------------------------------------------------

    \3\ This direct final rule is effective June 22, 2015, without 
further notice, unless EPA receives adverse comment by May 21, 2015. 
If EPA receives such comments, it will publish a timely withdrawal 
of the direct final rule in the Federal Register informing the 
public that this rule will not take effect. The associated proposed 
rule will remain in effect.
---------------------------------------------------------------------------

    Under section 182(a)(2)(A), states with ozone nonattainment areas 
that were designated prior to the enactment of the 1990 CAA amendments 
were required to submit, within six months of classification, all rules 
and corrections to existing VOC RACT rules that were required under 
section 172(b)(3) of the CAA (and related guidance) prior to the 1990 
CAA amendments. On June 23, 1994, EPA determined that North Carolina 
met the section 182(a)(2) RACT ``fix up'' requirements. See, e.g., 59 
FR 32363.
    Section 182(a)(2)(B) requires each state with a marginal ozone 
nonattainment area that implemented, or was required to implement, an 
inspection and maintenance (I/M) program prior to the 1990 CAA 
amendments to submit a SIP revision providing for an I/M program no 
less stringent than that required prior to the 1990 amendments or 
already in the SIP at the time of the amendments, whichever is more 
stringent. On June 2, 1995, EPA determined that North Carolina met 
requirements of section 182(a)(2)(B). See 60 FR 28720.
    Regarding the permitting and offset requirements of section 
182(a)(2)(C) and section 182(a)(4), North Carolina currently has a 
fully-approved part D NSR program in place. However, EPA has determined 
that areas being redesignated need not comply with the requirement that 
a NSR program be approved prior to redesignation, provided that the 
area demonstrates maintenance of the NAAQS without part D NSR, because 
PSD requirements will apply after redesignation. A more detailed 
rationale for this view is described in a memorandum from Mary Nichols, 
Assistant Administrator for Air and Radiation, dated October 14, 1994, 
entitled, ``Part D New Source Review Requirements for Areas Requesting 
Redesignation to Attainment.'' North Carolina's PSD program will become 
applicable in the bi-state Charlotte Area upon redesignation to 
attainment.
    Section 182(a)(3) requires states to submit periodic inventories 
and emissions statements. Section 182(a)(3)(A) requires states to 
submit a periodic inventory every three years. As discussed below in 
the section of this document titled Criteria (4)(e), Verification of 
Continued Attainment, the State will continue to update its emissions 
inventory at least once every three years. Under section 182(a)(3)(B), 
each state with an ozone nonattainment area must submit a SIP revision 
requiring emissions statements to be submitted to the state by sources 
within that nonattainment area. North Carolina provided a SIP revision 
to EPA on July 7, 2014, addressing the section 182(a)(3)(B) emissions 
statements requirement, and on April 21, 2015, EPA published a direct 
final rule to approve this SIP revision.\4\ See 80 FR 22107 (direct 
final rule) and 80 FR 22147 (associated proposed rule). North 
Carolina's emissions statements must be incorporated into the SIP 
before EPA can take final action to approve the State's redesignation 
request for the bi-state Charlotte Area.
---------------------------------------------------------------------------

    \4\ This direct final rule is effective June 22, 2015, without 
further notice, unless EPA receives adverse comment by May 21, 2015. 
If EPA receives such comments, it will publish a timely withdrawal 
of the direct final rule in the Federal Register informing the 
public that this rule will not take effect. The associated proposed 
rule will remain in effect.
---------------------------------------------------------------------------

    Section 176 Conformity Requirements. Section 176(c) of the CAA 
requires states to establish criteria and procedures to ensure that 
federally supported or funded projects conform to the air quality 
planning goals in the applicable SIP. The requirement to determine 
conformity applies to transportation plans, programs, and projects that 
are developed, funded, or approved under title 23 of the United States 
Code (U.S.C.) and the Federal Transit Act (transportation conformity) 
as well as to all other federally supported or funded projects (general 
conformity). State transportation conformity SIP revisions must be 
consistent with Federal conformity regulations relating to 
consultation, enforcement, and enforceability that EPA promulgated 
pursuant to its authority under the CAA.
    EPA interprets the conformity SIP requirements \5\ as not applying 
for purposes of evaluating a redesignation request under section 107(d) 
because state conformity rules are still required after redesignation 
and Federal conformity rules apply where state rules have not been 
approved. See Wall v. EPA, 265 F.3d 426 (6th Cir. 2001) (upholding this 
interpretation); see also 60 FR 62748 (December 7, 1995) (redesignation 
of Tampa, Florida). Nonetheless, North Carolina has an approved 
conformity SIP for the Charlotte Area. See 78 FR 73266 (February 24, 
2014). Thus, the North Carolina portion of the bi-state Charlotte Area 
has satisfied all applicable requirements for purposes of redesignation 
under section 110 and part D of title I of the CAA.
---------------------------------------------------------------------------

    \5\ CAA section 176(c)(4)(E) requires states to submit revisions 
to their SIPs to reflect certain Federal criteria and procedures for 
determining transportation conformity. Transportation conformity 
SIPs are different from the MVEBs that are established in control 
strategy SIPs and maintenance plans.
---------------------------------------------------------------------------

b. The North Carolina Portion of the Bi-State Charlotte Area Has a 
Fully Approved Applicable SIP Under Section 110(k) of the CAA
    EPA has fully approved the applicable North Carolina SIP for the 
bi-state

[[Page 29255]]

Charlotte Area under section 110(k) of the CAA for all requirements 
applicable for purposes of redesignation. EPA may rely on prior SIP 
approvals in approving a redesignation request (see Calcagni Memorandum 
at p. 3; Southwestern Pennsylvania Growth Alliance v. Browner, 144 F.3d 
984, 989-90 (6th Cir. 1998); Wall, 265 F.3d 426) plus any additional 
measures it may approve in conjunction with a redesignation action (see 
68 FR 25426 (May 12, 2003) and citations therein). North Carolina has 
adopted and submitted, and EPA has fully approved at various times, 
provisions addressing the various SIP elements applicable for the ozone 
NAAQS. See 77 FR 5703 (February 6, 2012).
    As indicated above, EPA believes that the section 110 elements that 
are neither connected with nonattainment plan submissions nor linked to 
an area's nonattainment status are not applicable requirements for 
purposes of redesignation. EPA has approved all part D requirements 
applicable for purposes of this redesignation. As noted above, this 
action to propose approval of North Carolina's redesignation request 
for the North Carolina portion of the bi-state Charlotte Area is 
contingent upon EPA taking final action to approve the July, 7, 2014, 
emissions inventory and emissions statements SIP revision, which was 
published as direct final and proposed rules on April 21, 2015. See 80 
FR 22107 and 80 FR 22147.

Criteria (3)--The Air Quality Improvement in the Bi-State Charlotte 
Area Is Due to Permanent and Enforceable Reductions in Emissions 
Resulting From Implementation of the SIP and Applicable Federal Air 
Pollution Control Regulations and Other Permanent and Enforceable 
Reductions

    For redesignating a nonattainment area to attainment, the CAA 
requires EPA to determine that the air quality improvement in the area 
is due to permanent and enforceable reductions in emissions resulting 
from implementation of the SIP, applicable Federal air pollution 
control regulations, and other permanent and enforceable reductions 
(CAA section 107(d)(3)(E)(iii)). EPA has preliminarily determined that 
North Carolina has demonstrated that the observed air quality 
improvement in the bi-state Charlotte Area is due to permanent and 
enforceable reductions in emissions resulting from Federal measures and 
from state measures adopted into the SIP. EPA does not have any 
information to suggest that the decrease in ozone concentrations in the 
bi-state Charlotte Area is due to unusually favorable meteorological 
conditions.
    State and Federal measures enacted in recent years have resulted in 
permanent emission reductions. Most of these emission reductions are 
enforceable through regulations. A few non-regulatory measures also 
result in emission reductions. The state and local measures that have 
been implemented to date and relied upon by North Carolina to 
demonstrate attainment and/or maintenance include the Clean Air Bill I/
M program and North Carolina's Clean Smokestacks Act. These measures 
are approved in the federally-approved SIP and thus are permanent and 
enforceable. The Federal measures that have been implemented include 
the following:
    Tier 2 vehicle and fuel standards. Implementation began in 2004 and 
requires all passenger vehicles in any manufacturer's fleet to meet an 
average standard of 0.07 grams of NOX per mile. 
Additionally, in January 2006 the sulfur content of gasoline was 
required to be on average 30 ppm which assists in lowering the 
NOX emissions. Most gasoline sold in North Carolina prior to 
January 2006 had a sulfur content of about 300 ppm.\6\
---------------------------------------------------------------------------

    \6\ North Carolina also identified Tier 3 Motor Vehicle 
Emissions and Fuel Standards as a federal measure. EPA issued this 
rule in April 28, 2014, which applies to light duty passenger cars 
and trucks. EPA promulgated this rule to reduce air pollution from 
new passenger cars and trucks beginning in 2017. Tier 3 emission 
standards will lower sulfur content of gasoline and lower the 
emissions standards.
---------------------------------------------------------------------------

    Large non-road diesel engines rule. This rule was promulgated in 
2004, and is being phased in between 2008 through 2014. This rule will 
also reduce the sulfur content in the nonroad diesel fuel. When fully 
implemented, this rule will reduce NOX, VOC, particulate 
matter, and carbon monoxide. These emission reductions are federally 
enforceable. EPA issued this rule in June 2004, which applies to diesel 
engines used in industries, such as construction, agriculture, and 
mining. It is estimated that compliance with this rule will cut 
NOX emissions from non-road diesel engines by up to 90 
percent nationwide. The non-road diesel rule was fully implemented by 
2010.
    Heavy-duty gasoline and diesel highway vehicle standards. EPA 
issued this rule in January 2001 (66 FR 5002). This rule includes 
standards limiting the sulfur content of diesel fuel, which went into 
effect in 2004. A second phase took effect in 2007, which further 
reduced the highway diesel fuel sulfur content to 15 ppm, leading to 
additional reductions in combustion NOX and VOC emissions. 
This rule is expected to achieve a 95 percent reduction in 
NOX emissions from diesel trucks and buses.
    Medium and heavy duty vehicle fuel consumption and GHG standards. 
These standards require on-road vehicles to achieve a 7 percent to 20 
percent reduction in CO2 emissions and fuel consumption by 
2018. The decrease in fuel consumption will result in a 7 percent to 20 
percent decrease in NOX emissions.
    Nonroad spark-ignition engines and recreational engines standards. 
The nonroad spark-ignition and recreational engine standards, effective 
in July 2003, regulate NOX, hydrocarbons, and carbon 
monoxide from groups of previously unregulated nonroad engines. These 
engine standards apply to large spark-ignition engines (e.g., forklifts 
and airport ground service equipment), recreational vehicles (e.g., 
off-highway motorcycles and all-terrain-vehicles), and recreational 
marine diesel engines sold in the United States and imported after the 
effective date of these standards. When all of the nonroad spark-
ignition and recreational engine standards are fully implemented, an 
overall 72 percent reduction in hydrocarbons, 80 percent reduction in 
NOX, and 56 percent reduction in carbon monoxide emissions 
are expected by 2020. These controls reduce ambient concentrations of 
ozone, carbon monoxide, and fine particulate matter.
    National Program for greenhouse gas (GHG) emissions and Fuel 
Economy Standards. The federal GHG and fuel economy standards apply to 
light-duty cars and trucks in model years 2012-2016 (phase 1) and 2017-
2025 (phase 2). The final standards are projected to result in an 
average industry fleet-wide level of 163 grams/mile of carbon dioxide 
(CO2) which is equivalent to 54.5 miles per gallon (mpg) if 
achieved exclusively through fuel economy improvements. The fuel 
economy standards result in less fuel being consumed, and therefore 
less NOX emissions released.
    Tennessee Valley Authority (TVA) Consent Decree/Federal Facilities 
Compliance Agreement. On April 14, 2011, TVA entered into a consent 
decree with Tennessee, Alabama, Kentucky, and North Carolina to resolve 
allegations of CAA violations at TVA's coal-fired power plants. The 
relief obtained in this consent decree was also secured in a Federal 
Facilities Compliance Agreement (FFCA) between EPA and TVA. The consent 
decree and FFCA establish system-wide caps on NOX and 
SO2 emissions at TVA's coal-fired facilities, declining to 
permanent levels of 52,000 tons of NOX in 2018 and

[[Page 29256]]

110,000 tons of SO2 in 2019, and require TVA to meet 
specific control requirements.\7\
---------------------------------------------------------------------------

    \7\ EPA notes that there are no sources covered by the consent 
decree/FFCA in North Carolina. Although the bi-state Charlotte Area 
may get residual benefits from the implementation of consent decree/
FFCA, EPA does not believe these measures are needed for the bi-
state Charlotte Area to attain or maintain the 2008 8-hour ozone 
NAAQS.
---------------------------------------------------------------------------

    Reciprocating Internal Combustion Engine (RICE) National Emissions 
Standards for Hazardous Air Pollutants (NESHAP).\8\ The RICE NESHAP is 
expected to result in a small decrease in VOC emissions. RICE owners 
and operators had to comply with the NESHAP by May 3, 2013.
---------------------------------------------------------------------------

    \8\ North Carolina also identified the NESHAP for industrial, 
commercial and institutional boilers as a federal measure. This 
NESHAP is also expected to result in a small decrease in VOC 
emissions. Boilers must comply with the NESHAP by January 31, 2016, 
for all states except North Carolina which has a compliance date in 
May 2019.
---------------------------------------------------------------------------

    Utility Mercury Air Toxics Standards (MATS) and New Source 
Performance Standards (NSPS). On February 16, 2012, EPA promulgated 
maximum achievable control technology regulations for coal- and oil-
fired EGUs, intended to reduce hazardous air pollutants emissions from 
EGUs. Although the MATS rule is not targeted at NOX 
emissions, it is expected to result in additional NOX 
reductions due to the retirement of older coal-fired units.
    NOX SIP Call. On October 27, 1998 (63 FR 57356), EPA issued the 
NOX SIP Call requiring the District of Columbia and 22 
states to reduce emissions of NOX, a precursor to ozone 
pollution, and providing a mechanism (the NOX Budget Trading 
Program) that states could use to achieve those reductions. Affected 
states were required to comply with Phase I of the SIP Call beginning 
in 2004 and Phase II beginning in 2007. By the end of 2008, ozone 
season emissions from sources subject to the NOX SIP Call 
dropped by 62 percent from 2000 emissions levels. All NOX 
SIP Call states have SIPs that currently satisfy their obligations 
under the NOX SIP Call; the NOX SIP Call 
reduction requirements are being met; and EPA will continue to enforce 
the requirements of the NOX SIP Call. Emission reductions 
resulting from regulations developed in response to the NOX 
SIP Call are therefore permanent and enforceable for the purposes of 
this action. There are four facilities located within the North 
Carolina portion of the Area that are subject to the NOX SIP 
Call. These facilities are located in Gaston, Lincoln, and Rowan 
Counties. Two coal-fired power plants (Buck and Riverbend) were retired 
on April 1, 2013, which resulted in additional emissions reductions. 
There is also a facility west of the Area, Cliffside, located in 
Cleveland County, and a facility north of the Area, Marshall, located 
in Catawba County which are also subject to the NOX SIP 
Call.
    CAIR/CSAPR. CAIR created regional cap-and-trade programs to reduce 
SO2 and NOX emissions in 27 eastern states, 
including North Carolina. See 70 FR 25162 (May 12, 2005). EPA approved 
North Carolina's CAIR regulations into the North Carolina SIP on 
October 5, 2007. See 72 FR 56914. In 2009, the CAIR ozone season 
NOX trading program superseded the NOX Budget 
Trading Program, although the emission reduction obligations of the 
NOX SIP Call were not rescinded. See 40 CFR 51.121(r) and 
51.123(aa). In 2008, the United States Court of Appeals for the 
District of Columbia Circuit (D.C. Circuit) initially vacated CAIR, 
North Carolina v. EPA, 531 F.3d 896 (D.C. Cir. 2008), but ultimately 
remanded the rule to EPA without vacatur to preserve the environmental 
benefits provided by CAIR, North Carolina v. EPA, 550 F.3d 1176, 1178 
(D.C. Cir. 2008). On August 8, 2011 (76 FR 48208), acting on the D.C. 
Circuit's remand, EPA promulgated CSAPR to address interstate transport 
of emissions and resulting secondary air pollutants and to replace 
CAIR. CSAPR requires substantial reductions of SO2 and 
NOX emissions from electric generating units (EGUs) in 28 
states in the Eastern United States.
    Implementation of CSAPR was scheduled to begin on January 1, 2012, 
when CSAPR's cap-and-trade programs would have superseded the CAIR cap 
and trade programs. Numerous parties filed petitions for review of 
CSAPR, and on December 30, 2011, the D.C. Circuit Court issued an order 
staying CSAPR pending resolution of the petitions and directing EPA to 
continue to administer CAIR. EME Homer City Generation, L.P. v. EPA, 
No. 11-1302 (D.C. Cir. Dec. 30, 2011), Order at 2.
    On August 21, 2012, the D.C. Circuit issued its ruling, vacating 
and remanding CSAPR to EPA and once again ordering continued 
implementation of CAIR. EME Homer City Generation, L.P. v. EPA, 696 
F.3d 7, 38 (D.C. Cir. 2012). The D.C. Circuit subsequently denied EPA's 
petition for rehearing en banc. EME Homer City Generation, L.P. v. EPA, 
No. 11-1302, 2013 WL 656247 (D.C. Cir. Jan. 24, 2013), at *1. EPA and 
other parties then petitioned the Supreme Court for a writ of 
certiorari, and the Supreme Court granted the petitions on June 24, 
2013. EPA v. EME Homer City Generation, L.P., 133 S. Ct. 2857 (2013).
    On April 29, 2014, the Supreme Court vacated and reversed the D.C. 
Circuit's decision regarding CSAPR, and remanded that decision to the 
D.C. Circuit Court to resolve remaining issues in accordance with its 
ruling. EPA v. EME Homer City Generation, L.P., 134 S. Ct. 1584 (2014). 
EPA moved to have the stay of CSAPR lifted in light of the Supreme 
Court decision. EME Homer City Generation, L.P. v. EPA, Case No. 11-
1302, Document No. 1499505 (D.C. Cir. filed June 26, 2014). In its 
motion, EPA asked the D.C. Circuit to toll CSAPR's compliance deadlines 
by three years so that the Phase 1 emissions budgets apply in 2015 and 
2016 (instead of 2012 and 2013), and the Phase 2 emissions budgets 
apply in 2017 and beyond (instead of 2014 and beyond). On October 23, 
2014, the D.C. Circuit granted EPA's motion and lifted the stay of 
CSAPR which was imposed on December 30, 2011. EME Homer City 
Generation, L.P. v. EPA, No. 11-1302 (D.C. Cir. Oct. 23, 2014), Order 
at 3. On December 3, 2014, EPA issued an interim final rule to clarify 
how EPA will implement CSAPR consistent with the D.C. Circuit Court's 
order granting EPA's motion requesting lifting the stay and tolling the 
rule's deadlines. See 79 FR 71663 (December 3, 2014) (interim final 
rulemaking). Consistent with that rule, EPA began implementing CSAPR on 
January 1, 2015. EPA expects that the implementation of CSAPR will 
preserve the reductions achieved by CAIR and result in additional 
SO2 and NOX emission reductions throughout the 
maintenance period.
    As mentioned above, the State measures that have been implemented 
include the following:
    Vehicle Emissions Inspection and Maintenance (I/M) Program. In 
1999, the North Carolina State Legislation passed the Clean Air Bill 
that expanded the on-road vehicle I/M program from 9 to 48 counties. It 
was phased-in in the Charlotte nonattainment area from July 1, 2002, 
through January 1, 2004. This program reduces NOX, VOC, and 
CO emissions. The I/M program was submitted to EPA for adoption into 
the SIP in August 2002 and was federally approved in October 2002. 
Therefore, these emission reductions are both state and federally 
enforceable.
    On February 5, 2015, EPA approved a change to North Carolina's I/M 
rules triggered by a state law which exempted plug-in vehicles and the 
three newest model year vehicles with less than 70,000 miles on their 
odometers from emission inspection in all areas in North

[[Page 29257]]

Carolina where I/M is required. In North Carolina's section 110(l) 
demonstration, the State showed that the change in the compliance rate 
from 95 percent to 96 percent more than compensates for the 
NOX and VOC emissions increase. EPA-approved change to the 
I/M rules was effective March 9, 2015, and are state and federally 
enforceable.
    Clean Smokestacks Act. This state law requires coal-fired power 
plants to reduce annual NOX emissions by 77 percent by 2009, 
and to reduce annual SO2 emissions by 49 percent by 2009 and 
73 percent by 2013. This law set a NOX emissions cap of 
56,000 tons/year for 2009 and SO2 emissions caps of 250,000 
tons/year and 130,000 tons/year for 2009 and 2013, respectively. The 
public utilities cannot meet these emission caps by purchasing emission 
credits. EPA approved the statewide emissions caps as part of the North 
Carolina SIP on September 26, 2011. In 2013, the power plants subject 
to this law had combined NOX emissions of 38,857 tons per 
year, well below the 56,000 tons per year cap. The emissions cap has 
been met in all subsequent years as well and is enforceable at both the 
federal and state level.

Criteria (4)--The North Carolina Portion of the Area Has a Fully 
Approved Maintenance Plan Pursuant to Section 175A of the CAA

    For redesignating a nonattainment area to attainment, the CAA 
requires EPA to determine that the area has a fully approved 
maintenance plan pursuant to section 175A of the CAA (CAA section 
107(d)(3)(E)(iv)). In conjunction with its request to redesignate the 
North Carolina portion of the bi-state Charlotte Area to attainment for 
the 2008 8-hour ozone NAAQS, NC DAQ submitted a SIP revision to provide 
for the maintenance of the 2008 8-hour ozone NAAQS for at least 10 
years after the effective date of redesignation to attainment. EPA 
believes that this maintenance plan meets the requirements for approval 
under section 175A of the CAA.
a. What is required in a maintenance plan?
    Section 175A of the CAA sets forth the elements of a maintenance 
plan for areas seeking redesignation from nonattainment to attainment. 
Under section 175A, the plan must demonstrate continued attainment of 
the applicable NAAQS for at least 10 years after the Administrator 
approves a redesignation to attainment. Eight years after the 
redesignation, the state must submit a revised maintenance plan 
demonstrating that attainment will continue to be maintained for the 10 
years following the initial 10-year period. To address the possibility 
of future NAAQS violations, the maintenance plan must contain 
contingency measures as EPA deems necessary to assure prompt correction 
of any future 2008 8-hour ozone violations. The Calcagni Memorandum 
provides further guidance on the content of a maintenance plan, 
explaining that a maintenance plan should address five requirements: 
The attainment emissions inventory, maintenance demonstration, 
monitoring, verification of continued attainment, and a contingency 
plan. As is discussed more fully below, EPA has preliminarily 
determined that North Carolina's maintenance plan includes all the 
necessary components and is thus proposing to approve it as a revision 
to the North Carolina SIP.
b. Attainment Emissions Inventory
    EPA is proposing to determine that the bi-state Charlotte Area has 
attained the 2008 8-hour ozone NAAQS based on quality-assured 
monitoring data for the 3-year period from 2012-2014. North Carolina 
selected 2014 as the base year (i.e., attainment emissions inventory 
year) for developing a comprehensive emissions inventory for 
NOX and VOC, for which projected emissions could be 
developed for 2015, 2018, 2022, and 2026. The attainment inventory 
identifies a level of emissions in the Area that is sufficient to 
attain the 2008 8-hour ozone NAAQS. North Carolina began development of 
the attainment inventory by first generating a baseline emissions 
inventory for the State's portion of the bi-state Charlotte Area. The 
projected summer day emission inventories have been estimated using 
projected rates of growth in population, traffic, economic activity, 
and other parameters. Naturally occurring emissions (i.e., biogenic 
emissions) are not included in the emissions inventory comparison, as 
these emissions are outside the State's control. In addition to 
comparing the final year of the plan (2026) to the base year (2014), 
North Carolina compared interim years to the baseline to demonstrate 
that these years are also expected to show continued maintenance of the 
2008 8-hour ozone standard.
    The emissions inventory is composed of four major types of sources: 
Point, area, on-road mobile, and non-road mobile. The complete 
descriptions of how the inventories were developed are discussed in the 
Appendix B of the April 16, 2015, submittal, which can be found in the 
docket for this action. Point source emissions are tabulated from data 
collected by direct on-site measurements of emissions or from mass 
balance calculations utilizing emission factors from EPA's AP-42 or 
stack test results. For each projected year's inventory, point sources 
are adjusted by growth factors based on Standard Industrial 
Classification codes generated using growth patterns obtained from 
County Business Patterns. For the electric generating utility sources, 
the estimated projected future year emissions were based on information 
provided by the utility company. For the sources that report to the 
EPA's Clean Air Markets Division, the actual 2014 average July day 
emissions were used. For the other Title V sources, the latest data 
available (2013) was used to represent 2014 base year emissions. For 
sources emitting less than 25 tons per year and subject to the 
emissions statement requirements, the most recently reported data 
(2013) was used to represent 2014 base year emissions. For the small 
sources that only report emissions every 5 years, the most recently 
reported data (2013) was used to represent 2014 base year emission, 
since emissions from these sources do not vary much from year to year. 
Rail yard and airport emissions reported were obtained from the EPA's 
2011 National Emission Inventory.
    For area sources, emissions are estimated by multiplying an 
emission factor by some known indicator of collective activity such as 
production, number of employees, or population. For each projected 
year's inventory, area source emissions are changed by population 
growth, projected production growth, or estimated employment growth.
    The non-road mobile sources emissions are calculated using EPA's 
NONROAD2008a model, with the exception of the railroad locomotives 
which were estimated by taking activity and multiplying by an emission 
factor. For each projected year's inventory, the emissions are 
estimated using EPA's NONROAD2008a model with activity input such as 
projected landing and takeoff data for aircraft.
    For on-road mobile sources, EPA's Motor Vehicle Emission Simulator 
(MOVES2014) mobile model is run to generate emissions. The MOVES2014 
model includes the road class vehicle miles traveled (VMT) as an input 
file and can directly output the estimated emissions. For each 
projected year's inventory, the on-road mobile sources emissions are 
calculated by running the MOVES mobile model for the future year with 
the projected VMT to generate emissions that take into consideration 
expected Federal tailpipe standards, fleet turnover, and new fuels.

[[Page 29258]]

    The 2014 NOX and VOC emissions for the North Carolina 
portion of the bi-state Charlotte Area, as well as the emissions for 
other years, were developed consistent with EPA guidance and are 
summarized in Tables 2 through 4 of the following subsection discussing 
the maintenance demonstration. See Appendix B of the April 16, 2015, 
submission for more detailed information on the emissions inventory.
c. Maintenance Demonstration
    The maintenance plan associated with the redesignation request 
includes a maintenance demonstration that:
    (i) Shows compliance with and maintenance of the 2008 8-hour ozone 
NAAQS by providing information to support the demonstration that 
current and future emissions of NOX and VOC remain at or 
below 2014 emissions levels.
    (ii) Uses 2014 as the attainment year and includes future emissions 
inventory projections for 2015, 2018, 2022, and 2026.
    (iii) Identifies an ``out year'' at least 10 years after the time 
necessary for EPA to review and approve the maintenance plan. Per 40 
CFR part 93, NOX and VOC MVEBs were established for the last 
year (2026) of the maintenance plan (see section VII below). 
Additionally, NC DAQ opted to establish sub-area MVEBs for an interim 
year (2014).
    (iv) Provides actual (2014) and projected emissions inventories, in 
tons per day (tpd), for the North Carolina portion of the bi-state 
Charlotte Area, as shown in Tables 2 through 4, below.

    In situations where local emissions are the primary contributor to 
nonattainment, such as the bi-state Charlotte Area, if the future 
projected emissions in the nonattainment area remain at or below the 
baseline emissions in the nonattainment area, then the ambient air 
quality standard should not be exceeded in the future. North Carolina 
has projected emissions as described previously and determined that 
emissions in the North Carolina portion of the bi-state Charlotte Area 
will remain below those in the attainment year inventory for the 
duration of the maintenance plan.
    As discussed in section VI of this proposed rulemaking, a safety 
margin is the difference between the attainment level of emissions 
(from all sources) and the projected level of emissions (from all 
sources) in the maintenance plan. The attainment level of emissions is 
the level of emissions during one of the years in which the area met 
the NAAQS. North Carolina selected 2014 as the attainment emissions 
inventory year for the North Carolina portion of the bi-state Charlotte 
Area. North Carolina calculated safety margins in its submittal for 
years 2015, 2018, 2022, and 2026. Because the initial sub-area MVEB 
year of 2014 is also the base year for the maintenance plan inventory, 
there is no safety margin, therefore, no adjustments were made to the 
sub-area MVEBs for 2014. The State has allocated a portion of the 2026 
safety margin to the 2026 sub-area MVEBs for the bi-state Charlotte 
Area.

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

    The State has decided to allocate a portion of the 2026 safety 
margin to the 2026 sub-area MVEBs to allow for unanticipated growth in 
VMT, changes and uncertainty in vehicle mix assumptions, etc., that 
will influence the emission estimations. NC DAQ developed and 
implemented a five-step approach for determining a factor to use to 
calculate the amount of safety margin to apply to the sub-area MVEBs. 
Based on this approach, NC DAQ has allocated 2.93 tpd (2650 kg/day) to 
the 2026 NOX MVEB and 2.83 tpd (2,569 kg/day) to the 2026 
VOC MVEB. After allocation of the available safety margin, the 
remaining safety margin was calculated

[[Page 29259]]

as 59.72 tpd for NOX and 10.15 tpd for VOC. This allocation 
and the resulting available safety margin for the North Carolina 
portion of the bi-state Charlotte Area are discussed further in section 
VI of this proposed rulemaking along with the sub-area MVEBs to be used 
for transportation conformity proposes.
d. Monitoring Network
    There are currently seven monitors measuring ozone in the North 
Carolina portion of the bi-state Charlotte Area. NC DAQ operates four 
of the monitors in the Area, whereas the Mecklenburg County Air Quality 
(MCAQ) Office operates three of the monitors in Mecklenburg County. The 
State of North Carolina, through NC DAQ, has committed to continue 
operation of all monitors in the North Carolina portion of the bi-state 
Charlotte Area in compliance with 40 CFR part 58 and have thus 
addressed the requirement for monitoring. EPA approved North Carolina's 
monitoring plan on November 25, 2013.
e. Verification of Continued Attainment
    The State of North Carolina, through NC DAQ, has the legal 
authority to enforce and implement the maintenance plan for the North 
Carolina portion of the Area. This includes the authority to adopt, 
implement, and enforce any subsequent emissions control contingency 
measures determined to be necessary to correct future ozone attainment 
problems.
    Large stationary sources are required to submit an emissions 
inventory annually to NC DAQ or MCAQ. NC DAQ commits to review these 
emissions inventories to determine if any unexpected growth in 
NOX emissions in the Area may endanger the maintenance of 
the 2008 8-hour ozone NAAQS. Additionally, as new VMT data are provided 
by the North Carolina Department of Transportation (NC DOT), NC DAQ 
commits to review these data and determine if any unexpected growth in 
VMT may endanger the maintenance of the 2008 8-hour ozone NAAQS.
    Additionally, under the Consolidated Emissions Reporting Rule 
(CERR) and Air Emissions Reporting Requirements (AERR), NC DAQ is 
required to develop a comprehensive, annual, statewide emissions 
inventory every three years that is due twelve to eighteen months after 
the completion of the inventory year. The AERR inventory years match 
the base year and final year of the inventory for the maintenance plan, 
and are within one or two years of the interim inventory years of the 
maintenance plan. Therefore, NC DAQ commits to compare the CERR and 
AERR inventories as they are developed with the maintenance plan to 
determine if additional steps are necessary for continued maintenance 
of the 2008 8-hour ozone NAAQS in this Area.
f. Contingency Measures in the Maintenance Plan
    Section 175A of the CAA requires that a maintenance plan include 
such contingency measures as EPA deems necessary to assure that the 
state will promptly correct a violation of the NAAQS that occurs after 
redesignation. The maintenance plan should identify the contingency 
measures to be adopted, a schedule and procedure for adoption and 
implementation, and a time limit for action by the state. A state 
should also identify specific indicators to be used to determine when 
the contingency measures need to be implemented. The maintenance plan 
must include a requirement that a state will implement all measures 
with respect to control of the pollutant that were contained in the SIP 
before redesignation of the area to attainment in accordance with 
section 175A(d).
    In the April 16, 2015, submittal, North Carolina affirms that all 
programs instituted by the State and EPA will remain enforceable and 
that sources are prohibited from reducing emissions controls following 
the redesignation of the Area. The contingency plan included in the 
submittal includes a triggering mechanism to determine when contingency 
measures are needed and a process of developing and implementing 
appropriate control measures. The primary trigger of the contingency 
plan will be a violation of the 2008 8-hour ozone NAAQS (i.e., when the 
three-year average of the 4th highest values is equal to or greater 
than 0.076 ppm at a monitor in the Area). The trigger date will be 60 
days from the date that the State observes a 4th highest value that, 
when averaged with the two previous ozone seasons' fourth highest 
values, would result in a three-year average equal to or greater than 
0.076 ppm.
    The secondary trigger will apply where no actual violation of the 
2008 8-hour ozone NAAQS has occurred, but where the State finds 
monitored ozone levels indicating that an actual ozone NAAQS violation 
may be imminent. A pattern will be deemed to exist when there are two 
consecutive ozone seasons in which the 4th highest values are 0.076 ppm 
or greater at a single monitor within the Area. The trigger date will 
be 60 days from the date that the State observes a 4th highest value of 
0.076 ppm or greater at a monitor for which the previous season had a 
4th highest value of 0.076 ppm or greater.
    Once the primary or secondary trigger is activated, the Planning 
Section of the NC DAQ, in consultation with SC DHEC and MCAQ, shall 
commence analyses including trajectory analyses of high ozone days and 
an emissions inventory assessment to determine those emission control 
measures that will be required for attaining or maintaining the 2008 8-
hour ozone NAAQS. By May 1 of the year following the ozone season in 
which the primary or secondary trigger has been activated, North 
Carolina will complete sufficient analyses to begin adoption of 
necessary rules for ensuring attainment and maintenance of the 2008 8-
hour ozone NAAQS. The rules would become State effective by the 
following January 1, unless legislative review is required.
    At least one of the following contingency measures will be adopted 
and implemented upon a primary triggering event:
     NOX Reasonably Available Control Technology on 
stationary sources with a potential to emit less than 100 tons per year 
in the North Carolina portion of the Charlotte nonattainment area;
     diesel inspection and maintenance program;
     implementation of diesel retrofit programs, including 
incentives for performing retrofits;
     additional controls in upwind areas.
    The NC DAQ commits to implement within 24 months of a primary or 
secondary trigger,\9\ at least one of the control measures listed above 
or other contingency measures that may be determined to be more 
appropriate based on the analyses performed.
---------------------------------------------------------------------------

    \9\ On May 4, 2015, Sheila Holman, Director of NC DENR's 
Division of Air Quality sent an email to Lynorae Benjamin, Chief of 
the Region 4 EPA's Air Regulatory Management Section to confirm that 
the State will address and correct any violation of the 2008 8-Hour 
Ozone NAAQS as expeditiously as practicable and within 18-24 months 
from a trigger activation. A copy of this clarification email is in 
the docket for this rulemaking.
---------------------------------------------------------------------------

    North Carolina has also developed a tertiary trigger that will be a 
first alert as to a potential air quality problem on the horizon. This 
trigger will be activated when a monitor in the Area has a 4th highest 
value of 0.076 ppm or greater, starting the first year after the 
maintenance plan has been approved. The trigger date will be 60 days 
from the date that the State observes a 4th highest value of 0.076 ppm 
or greater at any monitor.
    Once the tertiary trigger is activated, the Planning Section of the 
NC DAQ, in consultation with the SC DHEC and

[[Page 29260]]

MCAQ, shall commence analyses including meteorological evaluation, 
trajectory analyses of high ozone days, and emissions inventory 
assessment to understand why a 4th highest exceedance of the standard 
has occurred. Once the analyses are completed, the NC DAQ will work 
with SC DHEC, MCAQ and the local air awareness program to develop an 
outreach plan identifying any additional voluntary measures that can be 
implemented. If the 4th highest exceedance occurs early in the season, 
the NC DAQ will work with entities identified in the outreach plan to 
determine if the measures can be implemented during the current season; 
otherwise, NC DAQ will work with SC DHEC, MCAQ, and the local air 
awareness coordinator to implement the plan for the following ozone 
season.
    EPA has concluded that the maintenance plan adequately addresses 
the five basic components of a maintenance plan: The attainment 
emissions inventory, maintenance demonstration, monitoring, 
verification of continued attainment, and a contingency plan. 
Therefore, the maintenance plan SIP revision submitted by North 
Carolina for the State's portion of the Area meets the requirements of 
section 175A of the CAA and is approvable.

VI. What is EPA's analysis of North Carolina's proposed NOX and VOC 
sub-area MVEBs for the North Carolina portion of the area?

    Under section 176(c) of the CAA, new transportation plans, 
programs, and projects, such as the construction of new highways, must 
``conform'' to (i.e., be consistent with) the part of the state's air 
quality plan that addresses pollution from cars and trucks. Conformity 
to the SIP means that transportation activities will not cause new air 
quality violations, worsen existing violations, or delay timely 
attainment of the NAAQS or any interim milestones. If a transportation 
plan does not conform, most new projects that would expand the capacity 
of roadways cannot go forward. Regulations at 40 CFR part 93 set forth 
EPA policy, criteria, and procedures for demonstrating and assuring 
conformity of such transportation activities to a SIP. The regional 
emissions analysis is one, but not the only, requirement for 
implementing transportation conformity. Transportation conformity is a 
requirement for nonattainment and maintenance areas. Maintenance areas 
are areas that were previously nonattainment for a particular NAAQS but 
have since been redesignated to attainment with an approved maintenance 
plan for that NAAQS.
    Under the CAA, states are required to submit, at various times, 
control strategy SIPs and maintenance plans for nonattainment areas. 
These control strategy SIPs (including RFP and attainment demonstration 
requirements) and maintenance plans create MVEBs (or in this case sub-
area MVEBs) for criteria pollutants and/or their precursors to address 
pollution from cars and trucks. Per 40 CFR part 93, a MVEB must be 
established for the last year of the maintenance plan. A state may 
adopt MVEBs for other years as well. The MVEB is the portion of the 
total allowable emissions in the maintenance demonstration that is 
allocated to highway and transit vehicle use and emissions. See 40 CFR 
93.101. The MVEB serves as a ceiling on emissions from an area's 
planned transportation system. The MVEB concept is further explained in 
the preamble to the November 24, 1993, Transportation Conformity Rule 
(58 FR 62188). The preamble also describes how to establish the MVEB in 
the SIP and how to revise the MVEB.
    As part of the interagency consultation process on setting sub-area 
MVEBs, the DAQ held three conference calls with the Charlotte Regional 
Transportation Planning Organization (CRTPO)--Rocky River Rural 
Planning Organization (RRRPO), Gaston-Cleveland-Lincoln Metropolitan 
Planning Organization (GCLMPO), and Cabarrus Rowan Metropolitan 
Planning Organization (CRMPO) to determine what years to set sub-area 
MVEBs for the Charlotte maintenance plan. According to the 
transportation conformity rule, a maintenance plan must establish MVEBs 
for the last year of the maintenance plan (in this case, 2026). See 40 
CFR 93.118. The consensus formed during the interagency consultation 
process was that another MVEB should be set for the Charlotte 
maintenance plan base year of 2014.
    Accordingly, NC DAQ established separate sub-area MVEBs based on 
the latest Metropolitan Planning Organization jurisdictional boundaries 
such that sub-area MVEBs are established for the CRMPO (Cabarrus and 
Rowan Counties), for the CRTPO-RRRPO (Iredell, Mecklenburg and Union 
Counties), and for the GCLMPO (Gaston and Lincoln Counties) subareas. 
Although Cleveland County is included in the GCLMPO, it is not included

    As mentioned above, North Carolina has chosen to allocate a portion 
of the available 2026 safety margin to the NOX and VOC sub-
area MVEBs for 2026. As discussed in section VI of this proposed 
rulemaking, a safety margin is the difference between the attainment 
level of emissions (from all sources) and the projected level of 
emissions (from all sources) in the maintenance plan. The attainment 
level of emissions is the level of emissions during one of the years in 
which the area met the NAAQS. As discussed above, North Carolina has 
selected 2014 as the base year.
    Through this rulemaking, EPA is proposing to approve the sub-area 
MVEBs for NOX and VOC for 2014 and 2026 for the North 
Carolina portion of the bi-state Charlotte Area because EPA believes 
that the Area maintains the 2008 8-hour ozone NAAQS with the emissions 
at the levels of the budgets. Once the sub-area MVEBs for the North 
Carolina portion of the bi-state Charlotte Area are approved or found 
adequate (whichever is completed first), they must be used for future 
conformity determinations. After thorough review, EPA has preliminary 
determined that the budgets meet the adequacy criteria, as outlined in 
40 CFR 93.118(e)(4), and is proposing to approve the budgets because 
they are consistent with maintenance of the 2008 8-hour ozone NAAQS 
through 2026.

VII. What is the status of EPA's adequacy determination for the 
Proposed NOX and VOC sub-area MVEBs for 2014 and 2026 for the North 
Carolina portion of the area?

    When reviewing submitted ``control strategy'' SIPs or maintenance 
plans containing MVEBs, EPA may affirmatively find the MVEB contained 
therein adequate for use in determining transportation conformity. Once 
EPA affirmatively finds the submitted MVEB is adequate for 
transportation conformity purposes, that MVEB must be used by state and 
Federal agencies in determining whether proposed transportation 
projects conform to the SIP as required by section 176(c) of the CAA.
    EPA's substantive criteria for determining adequacy of a MVEB are 
set out in 40 CFR 93.118(e)(4). The process for determining adequacy 
consists of three basic steps: Public notification of a SIP submission, 
a public comment period, and EPA's adequacy determination. This process 
for determining the adequacy of submitted MVEBs for transportation 
conformity purposes was initially outlined in EPA's May 14, 1999, 
guidance, ``Conformity Guidance on Implementation of March 2, 1999, 
Conformity Court Decision.'' EPA adopted regulations to codify the 
adequacy process in the Transportation Conformity Rule Amendments for 
the ``New 8-Hour Ozone and PM2.5 National Ambient Air 
Quality Standards and Miscellaneous Revisions for Existing Areas; 
Transportation Conformity Rule Amendments--Response to Court Decision 
and Additional Rule Change,'' on July 1, 2004 (69 FR 40004). Additional 
information on the adequacy process for transportation conformity 
purposes is available in the proposed rule entitled, ``Transportation 
Conformity Rule Amendments: Response to Court Decision and Additional 
Rule Changes,'' 68 FR 38974, 38984 (June 30, 2003).
    As discussed earlier, North Carolina's maintenance plan includes 
NOX and VOC sub-arear MVEBs for the North Carolina portion 
of the bi-state Charlotte Area for 2014, an interim year of the 
maintenance plan, and 2026, the last year of the maintenance plan. EPA 
is reviewing the NOX and VOC sub-area MVEBs through the 
adequacy process. The North Carolina bi-state Charlotte Area 
NOX and VOC sub-area MVEBs, opened for public comment on 
EPA's adequacy Web site on March 17, 2015, found at: http://www.epa.gov/otaq/stateresources/transconf/currsips.htm. The EPA public 
comment period on adequacy for the sub-area MVEBs for 2014 and 2026 for 
the North Carolina portion of the bi-state Charlotte Area closed on 
April 16, 2015. No comments, adverse or otherwise, were received during 
EPA's adequacy process for the sub-area MVEBs associated with North 
Carolina's maintenance plan.
    EPA intends to make its determination on the adequacy of the 2014 
and 2026 sub-area MVEBs for the North Carolina portion of the bi-state 
Charlotte Area for transportation conformity purposes in the near 
future by completing the adequacy process that was started on March 17, 
2015. After EPA finds the 2014 and 2026 sub-area MVEBs adequate or 
approves them, the new sub-area MVEBs for NOX and VOC must 
be used for future transportation conformity determinations. For 
required regional emissions analysis years that involve 2014 through 
2026, the applicable 2014 sub-area MVEBs will be used and for 2026 and 
beyond, the applicable budgets will be the new 2026 sub-area MVEBs 
established in the maintenance plan, as defined in section VI of this 
proposed rulemaking.

VIII. What is the effect of EPA's proposed actions?

    EPA's proposed actions establish the basis upon which EPA may take 
final

[[Page 29262]]

action on the issues being proposed for approval today. Approval of 
North Carolina's redesignation request would change the legal 
designation of Mecklenburg County in its entirety, and the portion of 
Cabarrus, Gaston, Iredell, Lincoln, Rowan and Union Counties within the 
North Carolina portion of the bi-state Charlotte Area, as found at 40 
CFR part 81, from nonattainment to attainment for the 2008 8-hour ozone 
NAAQS. Approval of North Carolina's associated SIP revision would also 
incorporate a plan for maintaining the 2008 8-hour ozone NAAQS in the 
bi-state Charlotte Area through 2026 into the SIP. This maintenance 
plan includes contingency measures to remedy any future violations of 
the 2008 8-hour ozone NAAQS and procedures for evaluation of potential 
violations. The maintenance plan also establishes NOX and 
VOC sub-area MVEBs for 2014 and 2026 for the North Carolina portion of 
the bi-state Charlotte Area. The sub-area MVEBs are listed in Tables 6 
through 8 in Section VI. Additionally, EPA is notifying the public of 
the status of EPA's adequacy determination for the newly-established 
NOX and VOC sub-area MVEBs for 2014 and 2026 for the North 
Carolina portion of the bi-state Charlotte Area.

IX. Proposed Actions

    EPA is taking three separate but related actions regarding the 
redesignation and maintenance of the 2008 8-hour ozone NAAQS for the 
North Carolina portion of the bi-state Charlotte Area.
    EPA proposes to determine that the Charlotte Area has attained the 
2008 8-hour ozone standard by the July 20, 2015, required attainment 
date. EPA is proposing to determine that the entire bi-state Charlotte 
Area is attaining the 2008 8-hour ozone NAAQS, based on complete, 
quality-assured, and certified monitoring data for the 2012-2014 
monitoring period. EPA is also proposing to approve the maintenance 
plan for the North Carolina portion of the Area, including the 
NOX and VOC sub-area MVEBs for 2014 and 2026, into the North 
Carolina SIP (under CAA section 175A). The maintenance plan 
demonstrates that the Area will continue to maintain the 2008 8-hour 
ozone NAAQS and that the budgets meet all of the adequacy criteria 
contained in 40 CFR 93.118(e)(4) and (5). Further, as part of this 
action, EPA is describing the status of its adequacy determination for 
the NOX and VOC sub-area MVEBs for 2014 and 2026 in 
accordance with 40 CFR 93.118(f)(1). Within 24 months from the 
effective date of EPA's adequacy determination for the MVEBs or the 
publication date for the final rule for this action, whichever is 
earlier, the transportation partners will need to demonstrate 
conformity to the new NOX and VOC sub-area MVEBs pursuant to 
40 CFR 93.104(e).
    Additionally, EPA is proposing to determine that the North Carolina 
portion of the bi-state Charlotte Area has met the criteria under CAA 
section 107(d)(3)(E) for redesignation from nonattainment to attainment 
for the 2008 8-hour ozone NAAQS. On this basis, EPA is proposing to 
approve North Carolina's redesignation request for the North Carolina 
portion of the bi-state Charlotte Area. If finalized, approval of the 
redesignation request would change the official designation of 
Mecklenburg County in its entirety, and a portion of Cabarrus, Gaston, 
Iredell, Lincoln, Rowan and Union Counties in North Carolina, as found 
at 40 CFR part 81, from nonattainment to attainment for the 2008 8-hour 
ozone NAAQS.

X. Statutory and Executive Order Reviews

    Under the CAA, redesignation of an area to attainment and the 
accompanying approval of a maintenance plan under section 107(d)(3)(E) 
are actions that affect the status of a geographical area and do not 
impose any additional regulatory requirements on sources beyond those 
imposed by state law. A redesignation to attainment does not in and of 
itself create any new requirements, but rather results in the 
applicability 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. 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 that they meet the criteria of the CAA. 
Accordingly, these proposed actions merely propose to approve state law 
as meeting Federal requirements and do not impose additional 
requirements beyond those imposed by state law. For this reason, these 
proposed actions:
     Are 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);
     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 (Pub. L. 104-4);
     Do not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Are not economically significant regulatory actions based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Are not significant regulatory actions 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).
    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.
