Air Plan Approval; West Virginia; Redesignation of the Marshall 
Sulfur Dioxide Nonattainment Area to Attainment and Approval of the 
Area's Maintenance Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving a 
redesignation request and state implementation plan (SIP) revisions 
submitted by the State of West Virginia related to the 2010 primary 
national ambient air quality standard (NAAQS or Standard) for sulfur 
dioxide (SO2) (2010 SO2 NAAQS). Emissions of 
SO2 in the Marshall, West Virginia Area have been 
permanently reduced, a maintenance plan has been adopted that includes 
limits that assure continued attainment and monitored ambient 
SO2 readings in the nonattainment area are currently well 
below the 2010 SO2 NAAQS. The effect of this action changes 
the designation of the Marshall Area from nonattainment to attainment 
of the 2010 SO2 NAAQS. This action is being taken under the 
Clean Air Act (CAA).

DATES: This final rule is effective on November 25, 2020.

ADDRESSES: EPA has established a docket for this action under Docket ID 
Number EPA-R03-OAR-2020-0171. All documents in the docket are listed on

SUPPLEMENTARY INFORMATION:

I. Background

    The Marshall Area is comprised of the Clay, Franklin, and 
Washington Tax Districts of Marshall County, West Virginia. On March 
18, 2020, West Virginia, through the West Virginia Department of 
Environmental Protection (WVDEP), submitted a redesignation request for 
the Marshall, West Virginia SO2 Nonattainment Area (Marshall 
Area or Area). In conjunction with its request, WVDEP submitted SIP 
revisions comprised of a maintenance plan for the Area, SO2 
emissions limits for the Mitchell Power Plant (Mitchell), and a 
modeling analysis demonstrating that the Mitchell limits provide for 
attainment in the Area.
    The Marshall Area was designated nonattainment for the 2010 
SO2 NAAQS in the first round of designations for the NAAQS 
published on August 5, 2013, which became effective on October 4, 2013. 
Under CAA section 191(a), attainment plan SIPs were due for areas 
designated nonattainment in round one 18 months after the effective 
date of designation, or April 4, 2015. Such SIPs were required by CAA 
section 192(a) to provide for attainment of the NAAQS as expeditiously 
as practicable, but no later than five years from the effective date of 
nonattainment designation, or October 4, 2018. West Virginia submitted 
an attainment SIP on March 17, 2017 (2017 SIP).\1\ The SIP addressed 
the required elements of an attainment SIP under CAA section 172(c), 
including an attainment demonstration that the State asserted showed 
attainment of the 2010 SO2 NAAQS, SO2 emissions 
limits for the Mitchell Power Plant, reasonably available control 
measures including reasonably available control technology (RACM/RACT), 
reasonable further progress (RFP), contingency measures, and 
certification that nonattainment new source review (NNSR) permit 
program requirements were being met. The 2017 SIP included a West 
Virginia Compliance Order on Consent (2016 consent order) that required 
Kentucky Power Company, the operator of American Electric Power's (AEP) 
Mitchell Power Plant, to comply with an SO2 maximum 
emissions limit from Units 1 and 2, of 6,175 pounds per hour (lbs/hr) 
on a 30-day rolling average, along with associated monitoring, 
recordkeeping, and reporting requirements, starting on January 1, 2017. 
The March 18, 2020 submittal requesting redesignation included a 
demonstration showing the area is in attainment, a maintenance plan, 
contingency measures, and a December 2, 2019 consent order (2019 
consent order) with Kentucky Power for Mitchell with lower 
SO2 emissions limits based on modeling with a changed stack 
height. Specifically, the 2019 consent order establishes an 
SO2 emissions limit for Mitchell Units 1 and 2 as a maximum 
of 3,149 lbs/hr on a 30-day rolling average, with compliance parameters 
including continuous emissions monitoring, recordkeeping including a 
calculation of the daily 30-day average, reporting of deviations from 
the requirements and semi-annual compliance reporting. Compliance with 
the limits and other provisions in the 2019 consent order were required 
starting on January 1, 2020.
---------------------------------------------------------------------------

    \1\ On March 18, 2016, EPA made a finding of failure to submit 
nonattainment area SIPs for 19 nonattainment areas, including the 
Marshall Area. EPA's letter to West Virginia dated September 27, 
2017 confirmed that West Virginia's March 17, 2017 submittal 
corrected the deficiency identified in the finding.
---------------------------------------------------------------------------

    Under CAA section 110(k)(2) through (4), EPA was required to take 
action to approve or disapprove West Virginia's 2017 SIP within 12 
months of determining it to be complete, but EPA did not take timely 
action. Subsequently, the Center for Biological Diversity and other 
plaintiffs (CBD) sued EPA in the U.S. District Court for the Northern 
District of California seeking a court order to compel EPA's action on 
West Virginia's 2017 SIP and several other SIPs for other areas in the 
nation. Center for Biological Diversity, et al., v. Wheeler, No. 4:18-
cv-03544-YGR. That lawsuit resulted in the plaintiffs and EPA agreeing 
to a schedule, entered by the court as an order, for EPA to take action 
on the covered SIPs by certain deadlines. The court ordered deadline 
for EPA to take action on West Virginia's 2017 SIP is October 30, 2020. 
The order also provided that if EPA issues a redesignation to 
attainment for any area for which the order required EPA action on a 
submitted SIP covered by the order, then EPA's obligation to take 
action on that SIP's CAA section 172(c) elements would be automatically 
terminated. As noted in the proposal, this action to redesignate the 
Marshall, West Virginia nonattainment area to attainment and approve 
the submitted maintenance plan with a lower emissions limit than that 
contained in the 2017 SIP submission will moot EPA's requirement under 
the consent order to take action on the 2017 SIP.

[[Page 67662]]

II. Summary of SIP Revision and EPA Analysis

    West Virginia's March 18, 2020 redesignation request included a 
maintenance plan providing for continued attainment of the 
SO2 NAAQS for a period of ten years following redesignation 
of the Area, SO2 emissions limits for Mitchell, and a 
modeling analysis demonstrating that the Mitchell limits provide for 
attainment in the Area. West Virginia also requested that EPA 
incorporate the 2019 consent order into the SIP.
    Under CAA section 107(d)(3)(E), there are five criteria which must 
be met before a nonattainment area may be redesignated to attainment:
    1. EPA has determined that the relevant NAAQS has been attained in 
the area;
    2. The applicable implementation plan has been fully approved by 
EPA under section 110(k);
    3. EPA has determined that improvement in air quality is due to 
permanent and enforceable reductions in emissions resulting from the 
SIP, Federal regulations, and other permanent and enforceable 
reductions;
    4. EPA has fully approved a maintenance plan, including a 
contingency plan, for the area under section 175A of the CAA; and,
    5. The state has met all applicable requirements for the area under 
section 110 and part D. The June 30, 2020 proposal (85 FR 39505) 
provides a detailed discussion of each requirement and EPA's analysis 
of how each requirement was met and is not repeated here. To summarize 
the analysis in the notice of proposed rulemaking (NPRM), EPA 
determined that the modeling submitted as part of the maintenance plan 
for the redesignation request submitted on March 18, 2020 shows that 
the Marshall Area is attaining the 2010 SO2 NAAQS, that the 
air quality improvement in the Area is attributable to permanent and 
enforceable emission reductions at Mitchell, that the maintenance plan 
assures that the area will continue to attain the 2010 SO2 
NAAQS, and that West Virginia has met all applicable requirements under 
section 110 (general SIP requirements) and part D of title I of the CAA 
(SIP requirements for nonattainment areas) for purposes of this 
redesignation. On this basis, EPA finds that West Virginia has 
adequately addressed the five basic components necessary to redesignate 
the Marshall Area to attainment.
    EPA received one adverse comment on the proposal. To review the 
full comment received, refer to the Docket for this rule, as identified 
in the ADDRESSES section of this document. A summary of the comment 
received, and EPA's response are provided below.

III. Public Comment and EPA Response

    Comment: The commenter asserts that EPA needs to do more to 
guarantee that the Mitchell plant will not violate the NAAQS. 
Specifically, the commenter expresses concern that the result of the 
modeling for Mitchell Plant of 196.2 micrograms per cubic meter 
([micro]g/m\3\) is too close to 196.4 [micro]g/m\3\ (corresponding to 
the level of the NAAQS, which is 75 parts per billion (ppb)), and 
therefore does not provide an adequate margin of safety to protect 
public health. Also, that EPA improperly ``rounded up'' to obtain the 
value of 196.4 [micro]g/m\3\, and that 196.4 [micro]g/m\3\ is not 
equivalent to the NAAQS, which is expressed as 75 ppb. In addition, the 
commenter believes that if the AERMOD model was run with a finer grid, 
the results would show NAAQS violations, and questions the margin of 
error of the AERMOD model. Finally, the commenter asks how EPA expects 
the modeled areas to maintain the NAAQS and suggests that a monitor is 
needed near the Mitchell plant.
    Response: EPA disagrees with the commenter's assertion that more is 
needed to guarantee that the Mitchell plant will not cause a violation 
of the NAAQS. First, the 2010 SO2 NAAQS was set at a level 
which already provides for an adequate margin of safety, as required by 
CAA Section 109(b)(1). Section 109(b)(1) defines a primary standard as 
one where ``the attainment and maintenance of which, in the judgment of 
the Administrator, based on [the air quality] criteria and allowing an 
adequate margin of safety, are requisite to protect the public 
health.'' CAA section 109(b)(1). As noted when EPA set the 
SO2 standard, ``[t]hus, in selecting primary standards that 
include an adequate margin of safety, the Administrator is seeking not 
only to prevent pollution levels that have been demonstrated to be 
harmful but also to prevent lower pollutant levels that may pose an 
unacceptable risk of harm, even if the risk is not precisely identified 
as to nature or degree.'' 75 FR 35520, 35521 (June 22, 2010). Because 
the NAAQS already includes a margin of safety, the fact that the 99th 
percentile of maximum daily one-hour modeled concentrations averaged 
over five years is below the NAAQS of 196.4 [micro]g/m\3\ ensures that 
public health is protected.
    EPA also disagrees that EPA improperly ``rounded up'' to develop 
the 196.4 [micro]g/m\3\ value that is equivalent to the 75 ppb NAAQS 
standard. The commenter does not identify the number that was 
supposedly rounded up, so EPA cannot directly address that claim. EPA 
recognized the need to identify and apply a consistent value expressed 
in [micro]g/m\3\ that EPA considers equivalent to 75 ppb, so in the 
Round 3 intended designations (82 FR 41903), published September 5, 
2017, EPA determined a value of 196.4 [micro]g/m\3\ (based on 
calculations using all available significant figures) to be equivalent 
to 75 ppb. To avoid confusion, EPA is expecting attainment and 
redesignation demonstrations to show achievement with concentrations at 
or below precisely 196.4 [micro]g/m\3\.\2\ EPA concludes that the 
Marshall modeling results of 196.2 [micro]g/m\3\ demonstrate that the 
area meets the standard. Because monitoring data was also available for 
this area, EPA analyzed that data, which showed a design value for the 
most recent three-year period (2017 through 2019) of 8 ppb. This 
monitored data, which is from the same previously violating monitor 
that caused this area to be designated nonattainment in 2013 based on 
2009-2011 data, provides further evidence that SO2 emissions 
concentrations have greatly improved in this area and supports EPA's 
redesignation of the area to attainment.
---------------------------------------------------------------------------

    \2\ While some Round 3 designation TSDs explained that this 
value was ``equivalent . . . using a 2.619 ug/m\3\ conversion 
factor'' (more precisely, using a conversion factor of approximately 
2.6187), in fact EPA here was determining the concentration value in 
ug/m\3\ that is to be considered equivalent to 75 ppb, rather than 
the precise value of the conversion factor.
---------------------------------------------------------------------------

    Regarding the commenter's question about the margin of error for 
AERMOD, EPA notes that AERMOD is a refined, steady-state (both 
emissions and meteorology over a 1-hour time step), multiple source, 
air-dispersion model that was originally promulgated by the EPA as part 
of its December 2005 revision to the Guideline on Air Quality Models, 
and is the preferred model to use for industrial sources in this type 
of air quality analysis. Furthermore, AERMOD predicts concentrations in 
many areas within the nonattainment area, rather than just at the 
monitor location, and therefore provides a more robust set of 
concentration data to assess attainment within the area than would be 
provided by a few SO2 monitors. EPA believes that the use of 
AERMOD in this Redesignation Request and Maintenance Plan was an 
appropriate choice regardless of any potential ``margin of error'' in 
the model.
    EPA also disagrees with the commenter's assertion that a finer 
modeling grid resolution should have been used. EPA's Guidance for the 
1-

[[Page 67663]]

hour SO2 Nonattainment SIP Submissions states, ``Receptor 
placement should be of sufficient density to provide resolution needed 
to detect significant gradients in the concentrations with receptors 
placed closer together near the source to detect local gradients and 
placed farther apart away from the source'' (page A-9).\3\ The area of 
maximum concentration in this modeling analysis had a 100 meter spaced 
receptor grid, which is the finest scale in the modeling domain. One of 
the reasons which would call for a finer grid is if there were large 
elevation differences between the facility and the area of maximum 
concentration, and that is not the case here. The facility is 0.67 
kilometers (km) from the modeled maximum concentration and the 
elevation differences are minimal.

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

    Regarding the commenter's question regarding how the Mitchell plant 
will maintain the standard, as stipulated by CAA 175A, the state must 
submit a maintenance plan which demonstrates how the source within the 
Marshall Area will provide for maintenance of the standard for the next 
ten years. Eight years after the redesignation, the state must submit a 
revised maintenance plan demonstrating that attainment will continue to 
be maintained for the ten years following the initial ten-year period. 
To address the possibility of future NAAQS violations, the maintenance 
plan must also contain contingency measures to assure prompt correction 
of any future violations. Specifically, the maintenance plan should 
address five requirements: (1) An attainment emissions inventory; (2) a 
maintenance demonstration; (3) a commitment for continued air quality 
monitoring; (4) the verification of continued attainment; and (5) a 
contingency plan.\4\ As detailed in the NPRM for this action, WV 
submitted a maintenance plan adequately addressing these five 
components necessary to maintain the SO2 NAAQS in the 
Marshall Area.
---------------------------------------------------------------------------

    \4\ See Memorandum from John Calcagni, Director, Air Quality 
Management Division, EPA, ``Procedures for Processing Requests to 
Redesignate Areas to Attainment,'' September 4, 1992.
---------------------------------------------------------------------------

IV. Final Action

    EPA is making a finding that the Marshall Area has attained the 
2010 SO2 NAAQS, as demonstrated by a modeling analysis 
reflecting a new SO2 emission limit for the Mitchell Power 
Plant and reflecting evidence (described in the notice of proposed 
rulemaking) that the Mitchell Power Plant is meeting this limit. EPA is 
also determining that West Virginia has met the planning requirements 
necessary for EPA to redesignate the Marshall Area from nonattainment 
to attainment of the 2010 SO2 NAAQS, including the 
requirements for permanent and enforceable measures, submission of an 
approvable maintenance plan that will assure attainment for ten years 
after redesignation, and that all other applicable CAA requirements 
under section 110 and part D, as discussed in the NPRM for this rule, 
have been met. Therefore, EPA is approving the Marshall Area 
redesignation request, maintenance plan, SO2 emission limits 
and associated compliance parameters for Mitchell in a 2019 consent 
order, and the modeling demonstration showing that the limits provide 
for maintenance. EPA is taking these actions under the CAA.

IV. Incorporation by Reference

    In this document, EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with requirements of 1 CFR 
51.5, EPA is finalizing the incorporation by reference of West 
Virginia's 2010 SO2 Maintenance Plan for the Marshall Area 
and the Mitchell Power Plant Consent Order CO-SIP-C-2019-13 described 
in the amendments to 40 CFR part 52 set forth below. EPA has made, and 
will continue to make, these materials generally available through 
https://www.regulations.gov and at the EPA Region III Office (please 
contact the person identified in the FOR FURTHER INFORMATION CONTACT 
section of this preamble for more information). Therefore, these 
materials have been approved by EPA for inclusion in the SIP, have been 
incorporated by reference by EPA into that plan, are fully Federally 
enforceable under sections 110 and 113 of the CAA as of the effective 
date of the final rule of EPA's approval, and will be incorporated by 
reference in the next update to the SIP compilation.\5\

V. Statutory and Executive Order Reviews

A. General Requirements

    Under the CAA, redesignation of an area to attainment and the 
accompanying approval of the maintenance plan under CAA section 
107(d)(3)(E) are actions that affect the status of a geographical area 
and do not impose any additional regulatory requirements on sources 
beyond those required by state law. A redesignation to attainment does 
not in and of itself impose any new requirements, but rather results in 
the application of requirements contained in the CAA for areas that 
have been redesignated to attainment. Moreover, the Administrator is 
required to approve a SIP submission that complies with the provisions 
of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 
CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to 
approve state choices, provided 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 these reasons, 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);
     Is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because it is not a significant regulatory 
action under Executive Order 12866.
     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 67664]]

    The SIP is not approved to apply on any Indian reservation land as 
defined in 18 U.S.C. 1151 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 and will not 
impose substantial direct costs on tribal governments or preempt tribal 
law as specified by Executive Order 13175 (65 FR 67249, November 9, 
2000).

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 December 28, 2020. 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 approving the redesignation of the West Virginia 
Marshall Nonattainment Area and associated maintenance plan may not be 
challenged later in proceedings to enforce its requirements. (See CAA 
section 307(b)(2).)
