SUPPLEMENTARY INFORMATION:
I. Background
On June 29, 2020 (85 FR 38831), EPA published a notice of proposed
rulemaking (NPRM) for the State of West Virginia. In the NPRM, EPA
proposed approval of West Virginia's plan for maintaining the 1997
ozone NAAQS through June 14, 2027, in accordance with CAA section 175A.
The formal SIP revision was submitted by WVDEP on December 10, 2019.
II. Summary of SIP Revision and EPA Analysis
On May 15, 2007 (72 FR 27247, effective June 14, 2007), EPA
approved a redesignation request (and maintenance plan) from WVDEP for
the Wheeling Area. Per CAA section 175A(b), at the end of the eighth
year after the effective date of the redesignation, the state must also
submit a second maintenance plan to ensure ongoing maintenance of the
standard for an additional 10 years, and in South Coast Air Quality
Management District v. EPA (South Coast II),\1\ the D.C. Circuit held
that this requirement cannot be waived for areas, like the Wheeling
Area, that had been redesignated to attainment for the 1997 ozone NAAQS
prior to revocation and that were designated attainment for the 2008
ozone NAAQS. CAA section 175A sets forth the criteria for adequate
maintenance plans. In addition, EPA has published longstanding guidance
[[Page 16673]]
that provides further insight on the content of an approvable
maintenance plan, explaining that a maintenance plan should address
five elements: (1) An attainment emissions inventory; (2) a maintenance
demonstration; (3) a commitment for continued air quality monitoring;
(4) a process for verification of continued attainment; and (5) a
contingency plan.\2\ WVDEP's December 10, 2019 SIP submittal fulfills
West Virginia's obligation to submit a second maintenance plan and
addresses each of the five necessary elements.

\2\ ``Procedures for Processing Requests to Redesignate Areas to
Attainment,'' Memorandum from John Calcagni, Director, Air Quality
Management Division, September 4, 1992 (Calcagni Memo).
---------------------------------------------------------------------------
As discussed in the June 29, 2020 NPRM, consistent with
longstanding EPA's guidance,\3\ areas that meet certain criteria may be
eligible to submit a limited maintenance plan (LMP) to satisfy one of
the requirements of CAA section 175A. Specifically, states may meet CAA
section 175A's requirements to ``provide for maintenance'' by
demonstrating that the area's design values \4\ are well below the
NAAQS and that it has had historical stability attaining the NAAQS. EPA
evaluated WVDEP's December 10, 2019 submittal for consistency with all
applicable EPA guidance and CAA requirements. EPA found that the
submittal met CAA section 175A and all CAA requirements, and proposed
approval of the LMP for the Wheeling, WV-OH Area comprising Marshall
and Ohio Counties as a revision to the West Virginia SIP. The effect of
this action makes certain commitments related to the maintenance of the
1997 ozone NAAQS federally enforceable as part of the West Virginia
SIP. Other specific requirements of WVDEP's December 10, 2019 submittal
and the rationale for EPA's proposed action are explained in the NPRM
and will not be restated here.

dated August 9, 2001.
\4\ The ozone design value for a monitoring site is the 3-year
average of the annual fourth-highest daily maximum 8-hour average
ozone concentrations. The design value for an ozone nonattainment
area is the highest design value of any monitoring site in the area.
---------------------------------------------------------------------------
III. EPA's Response to Comments Received
EPA received four comments on the June 29, 2020 NPRM. All comments
received are in the docket for this rulemaking action. A summary of the
comments and EPA's responses are provided herein.
Comment 1: The commenter alleges that the plan should not be
approved due to the allowance of future expansion of Interstate 70 (I-
70) within Ohio County in West Virginia and Belmont County in Ohio from
a West Virginia ``transportation conformity plan.'' The commenter takes
issue that the ``transportation conformity plan'' will allow more
vehicles to use the highway, hence increasing the vehicle miles
traveled (VMT) and the mobile source emissions. The commenter claims
that ``EPA should require WV to compensate'' for the increase in VMT
arising from the future expansion project and suggests that this could
be evaluated by utilizing ``actual VMT data collected on I-70'' in the
motor vehicle emission simulator (MOVES) modeling and the modeling
``will show an increase in mobile source emissions in the area beyond
that shown in WV's plan.''
Response 1: EPA does not agree with the commenter that the plan
should not be approved for the reasons given in the comment. The
commenter did not identify a specific project that would expand the I-
70 as it exists today. In an effort to identify the project that the
commenter referred to, we reviewed West Virginia's current statewide
transportation improvement program (STIP) and the current long-range
transportation plan for the West Virginia portion of the Wheeling
metropolitan area which includes Marshall and Ohio Counties. We could
not identify any I-70 expansion projects in the STIP.\5\ We did
identify several bridge rehabilitation projects on I-70, but these
would not constitute highway expansion projects and would not result in
increased vehicle miles traveled. We did identify one highway expansion
project in the area's long-range transportation plan.\6\ That project
would upgrade I[hyphen]70 to six lanes from Elm Grove/Triadelphia
interchange to Cabela Drive in Ohio County. Construction is not slated
to begin until 2036. The opening date for the project is not stated in
the long-range plan. Belomar, the metropolitan planning organization
for the area, will have to consider the potential impacts of this
project on air quality in the area when it makes transportation
conformity determinations for the 1997 ozone NAAQS. However, with
respect to the commenter's request that compensating emissions
reductions be obtained for any emissions increases that this project
may eventually cause, there is no mechanism under the CAA that requires
such compensating emissions reductions as part of a maintenance plan.
In order to approve the second maintenance plan for the area, the plan
must demonstrate that the area will be able to remain in attainment of
the 1997 ozone NAAQS through 2027. We have reviewed the second
maintenance plan and for the reasons stated in this final rule and in
the proposal, we have concluded that the second maintenance plan is
approvable. 85 FR 38831 (June 29, 2020).

\6\ https://www.belomar.org/wordpress/wp-content/uploads/2016/07/bomts-lrp-2040-final-document.pdf.
---------------------------------------------------------------------------
Comment 2: The commenter claims that the second maintenance plan
should be rejected because ``EPA has not evaluated the loss in emission
reductions'' due to certain policy positions taken by the Trump
administration related to ``. . . the CAFE \7\ standards, biofuel
blending requirements and removing States' and California's ability to
set standards.'' The commenter asserts that West Virginia failed to use
``reduced emission standards'' in the mobile source evaluation. The
commenter contends that West Virginia ``uses assumptions that are
against EPA's stated policy under the New Source Performance Standards
(NSPS) and the National Emission Standards for Hazardous Pollutants
(NESHAP)'' and therefore, the plan should be rejected. Further, the
commenter takes issue that ``Recently EPA has announced protections
under the mercury and air toxic standards (MATS) rule and the Boiler
maximum achievable control technology (MACT) rule,'' and due to the
removal of these programs, ``EPA should require states to use those
planning assumptions and account for any lost emissions reductions
achieved by those programs.''
---------------------------------------------------------------------------
\7\ Corporate Average Fuel Economy (CAFE).
---------------------------------------------------------------------------
Response 2: It is unclear from the comment how or why the commenter
believes the particular policies cited are relevant to this action. For
example, biofuel blending requirements are not relevant to ozone
reductions, and neither West Virginia nor Ohio has adopted California's
light duty vehicle emission standards, and therefore, neither state is
impacted by the withdrawal of California's waiver for its zero emission
vehicle sales mandate and its greenhouse gas emissions standards.\8\
The change to the National Highway
[[Page 16674]]
Traffic Safety Administration's (NHTSA) corporate average fuel economy
rules and EPA's greenhouse gas emissions standards did not affect EPA's
Tier 3 vehicle and fuel regulation.\9\ Therefore, new vehicles continue
to be required to be certified to the Tier 3 emissions standards for
nitrogen oxides (NOX) and volatile organic compounds (VOCs).
Neither of the Safer Affordable Fuel-Efficient (SAFE) rulemakings
affected emissions from the existing vehicle fleet. For the reasons
stated in the NPRM, we disagree with alleged deficiencies in evaluating
mobile sources.
---------------------------------------------------------------------------
\8\ See 84 FR 51310, September 27, 2019. The Safer Affordable
Fuel-Efficient (SAFE) Vehicles Rule Part One: One National Program.
\9\ See 85 FR 24174, April 30, 2020. The Safer Affordable Fuel-
Efficient (SAFE) Vehicles Rule for Model Years 2021-2026 Passenger
Cars and Light Trucks.
---------------------------------------------------------------------------
We also do not agree with the commenter's contentions about West
Virginia using ``assumptions that are against EPA's stated policy under
NSPS and NESHAP,'' or that EPA should require West Virginia to address
the removal of protections the commenter alleges EPA has made under the
MATS and Boiler MACT rules. The commenter does not identify how any
NSPS or NESHAP ``policies'' impact this action, or which policies,
NESHAPs or NSPS the commenter believes are relevant to this action.
With respect to MATS and the Boiler MACT, the commenter incorrectly
assumes that protections under those rules have been ``removed.'' In a
2020 rulemaking, EPA found that it was not ``appropriate and
necessary'' to regulate hazardous air pollutants (HAP) emissions from
coal- and oil-fired Electrical Generating Units (EGUs), thereby
reversing the Agency's previous conclusion under CAA section
112(n)(1)(A). 85 FR 31286 (May 22, 2020). This action did not, however,
remove the EGUs covered by MATS from regulation. EPA explicitly stated
that coal- and oil-fired EGUs would remain on the CAA section 112(c)(1)
source category list, and that the CAA section 112(d) standards for
those EGUs, as promulgated in the MATS rule, would be unaffected by its
reversal of the ``appropriate and necessary'' finding because EPA had
not met the statutorily required CAA section 112(c)(9) delisting
criteria to remove these units from regulation. 85 FR at 31286 (May 22,
2020).\10\ The commenter is therefore incorrect that there has been any
``removal of protections'' with respect to the emission limits required
under the MATS rule. Similarly, although EPA has proposed certain
changes to the Boiler MACT in response to a court decision,\11\ those
proposed changes have not been finalized to date. Therefore, the
environmental protections of neither the MATS rule nor the Boiler MACT
rule have been removed or decreased. EPA therefore disagrees with the
commenter that this plan should be disapproved because of WVDEP's
failure to address, in a plan designed to maintain an ozone standard,
the CAA programs and policies referenced by the commenter.
---------------------------------------------------------------------------
\10\ We note also that the 2020 rulemaking has been challenged
in the Court of Appeals for the District of Columbia and has also
been identified by President Biden's January 20, 2021 Executive
Order as an action that EPA should propose to review, revise, or
rescind by August 2021.
\11\ 85 FR 52198 (August 24, 2020).
---------------------------------------------------------------------------
Comment 3: The commenter asserts that the LMP should not be
approved because of EPA's reliance on the Air Quality Modeling
Technical Support Document (TSD) that was developed for EPA's regional
transport rulemaking. The commenter contends that: (1) The TSD shows
maintenance of the area for three years and not 10 years; (2) the
modeling was performed for transport purposes across state lines and
not to show maintenance of the NAAQS; (3) the modeling was performed
for the 2008 and 2015 ozone NAAQS and not the 1997 ozone NAAQS; (4) the
TSD has been ``highly contested'' by environmental groups and that
``other states contend EPA's modeling as flawed;'' and (5) the TSD does
not address a recent court decision that threw out EPA's modeling
``because it modeled to the wrong attainment year. . . .'' The
commenter asserts that the four specific issues it raises with respect
to the modeling means that the TSD is ``flawed, illegal, [and] is being
used improperly for the wrong purpose. . . .'' The commenter states
that ``EPA must retract its reliance on the modeling for the purposes
of this maintenance plan and must find some other way of showing
continued maintenance of the 1997 ozone NAAQS.''
Response 3: EPA does not agree with the commenter that the approval
of West Virginia's second maintenance plan is not appropriate. The
commenter raises concerns about West Virginia and EPA's citation of air
quality modeling, but the commenter ignores that EPA's primary basis
for finding that West Virginia has provided for maintenance of the 1997
ozone NAAQS in the Wheeling Area is the State's demonstration that the
criteria for a limited maintenance plan has been met. See 85 FR 38831,
June 29, 2020. Specifically, as stated in the NPRM, for decades EPA has
interpreted the provision in CAA section 175A that requires states to
``provide for maintenance'' of the NAAQS to be satisfied where areas
demonstrate that design values are and have been stable and well below
the NAAQS--e.g., at 85% of the standard, or in this case at or below
0.071 ppm. EPA calls such demonstration a ``limited maintenance plan.''
The modeling cited by the commenter was referenced in West
Virginia's submission and as part of EPA's proposed approval as
supplementary supporting information, and we do not agree that the
commenter's concerns about relying on that modeling are warranted. The
commenter contends that the modeling only goes out three years (to
2023) and it needs to go out to 10 years, and therefore may not be
relied upon. However, the air quality modeling TSD was only relied upon
by EPA to provide additional support to indicate that the area is
expected to continue to attain the NAAQS during the relevant period. As
noted above, West Virginia primarily met the requirement to demonstrate
maintenance of the NAAQS by showing that they met the criteria for a
limited maintenance plan, rather than by modeling or projecting
emissions inventories out to a future year. We also do not agree that
the State is required to demonstrate maintenance for 10 years; CAA
section 175A requires the State to demonstrate maintenance through the
20th year after the area is redesignated, which in this case is 2027.
We also disagree with the commenter's contention that because the
air quality modeling TSD was performed to analyze the transport of
pollution across state lines with respect to other ozone NAAQS, it
cannot be relied upon in this action. We acknowledge that the air
quality modeling TSD at issue was performed as part of EPA's efforts to
address interstate transport pollution under CAA section
110(a)(2)(D)(i)(I). However, the purpose of the air quality modeling
TSD is fully in keeping with the question of whether West Virginia is
expected to maintain the NAAQS. The air quality modeling TSD identifies
which air quality monitors in the United States are projected to have
problems attaining or maintaining the 2008 and 2015 NAAQS for ozone in
2023. Because the air quality modeling TSD results simply provide
projected ozone concentration design values, which are expressed as
three-year averages of the annual fourth high 8-hour daily maximum
ozone concentrations, the modeling results are useful for analyzing
attainment and maintenance of any of the ozone NAAQS that are measured
using this averaging time; in this case, the 1997, 2008 and 2015 ozone
NAAQS. The only difference between the three standards
[[Page 16675]]
is stringency. Taking the Wheeling Area's most recent certified design
value as of the proposal (i.e., for the years 2016-2018), the area's
design value was 0.066 parts per million (ppm). What we can discern
from this is that the area is meeting the 1997 ozone NAAQS of 0.080
ppm, the 2008 ozone NAAQS of 0.075 ppm, and the 2015 ozone NAAQS of
0.070 ppm. The same principle applies to projected design values from
the air quality modeling TSD. In this case, the interstate transport
modeling indicated that in 2023, the Wheeling Area's design value is
projected to be 0.067 ppm,\12\ which is again, well below all three
standards. The fact that the air quality modeling TSD was performed to
indicate whether the area will have problems attaining or maintaining
the 2015 ozone NAAQS (i.e., 0.070 ppm) does not make the modeling less
useful for determining whether the area will also meet the less
stringent revoked 1997 standard (i.e., 0.080 ppm).
---------------------------------------------------------------------------
\12\ The June 29, 2020 NPRM for this action recited 0.060 ppm as
the Projected 2023 design value in Table 2--Wheeling Area 8-hour
Ozone Design Value in Part Per Million. Through this final action we
clarify that the correct Projected 2023 design value that was
included in the State's submission, is 0.067 ppm. The inclusion of
the slightly higher but incorrect figure in the NPRM is a harmless
error that does not alter EPA's approval of this LMP.
---------------------------------------------------------------------------
The commenter asserts that many groups have criticized EPA's
transport modeling, alleging that the agency used improper emissions
inventories, incorrect contribution thresholds, wrong modeling years,
or that EPA has not accounted for local situations or reductions that
occurred after the inventories were established. The commenter also
alleges that EPA should not rely on its modeling because it ``fails to
stand up to the recent court decisions,'' citing the Wisconsin v. EPA
D.C. Circuit decision.\13\ EPA disagrees that the existence of
criticisms of the agency's air quality modeling TSD render it
unreliable, and we also do not agree that anything in recent court
decisions, including Wisconsin v. EPA, suggests that EPA's air quality
modeling TSD is technically flawed. We acknowledge that the source
apportionment air quality modeling TSD runs cited by the commenter have
been at issue in various legal challenges to EPA actions, including the
Wisconsin v. EPA case. However, in that case, the only flaw in EPA's
air quality modeling TSD identified by the D.C. Circuit was the fact
that its analytic year did not align with the attainment date found in
CAA section 181.\14\ Contrary to the commenter's suggestion, the D.C.
Circuit upheld EPA's air quality modeling TSD with respect to the many
technical challenges raised by petitioners in the Wisconsin case.\15\
We therefore think reliance on the interstate transport air quality
modeling TSD as supplemental support for showing that the Wheeling Area
will maintain the 1997 ozone NAAQS through the end of its 20th-year
maintenance period is appropriate.

---------------------------------------------------------------------------
Comment 4: The commenter asserts that EPA should disapprove this
maintenance plan because EPA should not allow states to rely on
emission programs such as the Cross-State Air Pollution rule (CSAPR) to
demonstrate maintenance for the 1997 ozone NAAQS. The commenter alleges
that ``the CSAP and CSAP Update and CSAP Close-out rules were vacated
entirely'' by multiple courts and ``are now illegal programs providing
no legally enforceable emission reductions to any states formerly
covered by the rules.'' The commenter also asserts that nothing
restricts ``big coal and gas power plants from emitting way beyond
there (sic) restricted amounts.'' The commenter does allow that ``If
EPA can show that continued maintenance without these rules is possible
for the next 10 years then that would be OK but as the plan stands it
relies on these reductions and must be disapproved.''
Response 4: The commenter has misapprehended the factual
circumstances regarding these interstate transport rules. Every rule
cited by the commenter that achieves emission reductions from electric
generating units (EGUs or power plants)--i.e., the Cross-State Air
Pollution Rule and the CSAPR Update--remains in place and continues to
ensure emission reductions of NOX and sulfur dioxide
(SO2). CSAPR began implementation in 2015 (after it was
largely upheld by the Supreme Court) and the CSAPR Update began
implementation in 2017. The latter rule was remanded to EPA to address
the analytic year issues discussed in the prior comment and response,
but the rule remains fully in effect. The commenter is correct that the
D.C. Circuit vacated the CSAPR close-out, but we note that that rule
was only a determination that no further emission reductions were
required to address interstate transport obligations for the 2008 ozone
NAAQS; the rule did not itself establish any emission reductions. We
therefore disagree that the legal status of these rules presents any
obstacle to EPA's approval of West Virginia's submission.
IV. Final Action
EPA is approving the 1997 ozone NAAQS limited maintenance plan for
the Wheeling, WV-OH area comprising Marshall and Ohio Counties as a
revision to the West Virginia SIP.
V. Statutory and Executive Order Reviews
A. General Requirements
Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the CAA 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, 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).
[[Page 16676]]
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.
B. Submission to Congress and the Comptroller General
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).
C. Petitions for Judicial Review
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 June 1, 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 pertaining to West Virginia's limited maintenance plan
for the Wheeling, WV-OH area comprising Marshall and Ohio Counties may
not be challenged later in proceedings to enforce its requirements.
