Approval and Promulgation of Air Quality Implementation Plans; 
West Virginia; Regional Haze Plan and Visibility Requirements for the 
2010 Sulfur Dioxide and the 2012 Fine Particulate Matter Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve a state implementation plan (SIP) revision submitted by the 
State of West Virginia (West Virginia) to change reliance on the Clean 
Air Interstate Rule (CAIR) to reliance on the Cross-State Air Pollution 
Rule (CSAPR) with the purpose of addressing certain regional haze 
requirements and visibility protection requirements for the 2010 sulfur 
dioxide (SO2) national ambient air quality standards 
(NAAQS). Upon EPA's final approval of this SIP revision, EPA is 
proposing to convert the Agency's June 7, 2012 limited approval/limited 
disapproval of West Virginia's regional haze SIP to a full approval; 
and EPA is proposing to remove the federal implementation plan (FIP) 
for West Virginia issued to address deficiencies previously identified 
in the Agency's limited approval/limited disapproval of the State's 
regional haze SIP revision. In addition, EPA is proposing to approve 
the portions of two previous SIP revisions submitted by West Virginia 
to address visibility protection requirements for the 2010 
SO2 and the 2012 particulate matter (PM2.5) 
NAAQS. These proposed actions are supported by EPA's recent final 
determination that a state's participation in CSAPR continues to meet 
EPA's regional haze criteria to qualify as an alternative to the 
application of best available retrofit

SUPPLEMENTARY INFORMATION: On September 16, 2015, the State of West 
Virginia via the West Virginia Department of Environmental Protection 
(WVDEP) submitted a revision to update its regional haze plan and to 
meet the visibility protection requirements in section 110(a)(2)(D) of 
the CAA.

I. Background

A. Regional Haze and the Relationship With CAIR and CSAPR

    In section 169A of the 1977 Amendments to the CAA, Congress created 
a program for protecting visibility in the nation's national parks and 
wilderness areas. This section of the CAA establishes ``as a national 
goal the prevention of any future, and the remedying of any existing, 
impairment of visibility in mandatory Class I federal areas which 
impairment results from manmade air pollution.'' \1\ On December 2, 
1980, EPA promulgated regulations to address visibility impairment in 
Class I areas that are reasonably attributable to a single source or 
small group of sources.\2\ Then, in 1990 Congress added section 169B to 
the CAA to address regional haze issues. EPA subsequently promulgated 
regulations pursuant to section 169B to address regional haze, known as 
the Regional Haze Rule.\3\ The Regional Haze Rule focuses on visibility 
impairment that is caused by the emission of air pollutants from 
numerous sources located over a wide geographic area, requiring states 
to establish goals and emission reduction strategies for improving 
visibility in Class I areas.
---------------------------------------------------------------------------

    \1\ 42 U.S.C. 7491(a). Mandatory Class I federal areas are 
defined as national parks exceeding 6,000 acres, wilderness areas 
and national memorial parks exceeding 5,000 acres, and all 
international parks that were in existence on August 7, 1977. 42 
U.S.C. 7472(a). In accordance with section 169A of the CAA, EPA, in 
consultation with the Department of Interior, promulgated a list of 
156 mandatory Class I federal areas where visibility is identified 
as an important value. 44 FR 69122 (November 30, 1979). When we use 
the term Class I area in this action, we mean a mandatory Class I 
federal area.
    \2\ These regulations are the reasonably attributable visibility 
impairment (RAVI) provisions. 45 FR 80084 (December 2, 1980).
    \3\ 64 FR 35714, 35714 (July 1, 1999) (codified at 40 CFR part 
51, subpart P).
---------------------------------------------------------------------------

    The CAA requires each state to develop, and submit for approval by 
EPA, a SIP to meet various air quality requirements, including the 
protection of visibility in Class I areas.\4\ Section 169A(b)(2) of the 
CAA requires that applicable states \5\ SIPs must contain such emission 
limits, schedules of compliance and other measures as may be necessary 
to make reasonable progress toward meeting the national visibility 
goal. Such measures include the application of BART by any BART-
eligible sources \6\ that emit air pollutants such as SO2 
and nitrogen oxides (NOX) \7\ that may reasonably be 
anticipated to cause or contribute to visibility impairment in a Class 
I area. The BART provisions of the Regional Haze Rule generally direct 
states to follow these steps to address the BART requirements: (1) 
Identify all BART-eligible sources; (2) determine which of those 
sources may reasonably be anticipated to cause or contribute to 
visibility impairment in a Class I area, and are therefore subject to 
BART requirements; (3) determine source-specific BART for each source 
that is subject to BART requirements; and (4) include the emission 
limitations reflecting those BART determinations in their SIPs.\8\ 
However, the Regional Haze Rule also provides states with the 
flexibility to adopt an emissions trading program or other alternative 
program instead of requiring source-specific BART controls, as long as 
the alternative provides greater reasonable progress towards the 
national goal of achieving natural visibility conditions in Class I 
areas than BART. See 40 CFR 51.308(e)(2).
---------------------------------------------------------------------------

    \4\ 42 U.S.C. 7410(a), 7491, and 7492(a), CAA sections 110(a), 
169A, and 169B.
    \5\ States that have a federal Class I area, listed by the 
Administrator under subsection 169A(a)(2) of the CAA, and/or states 
from which the emissions may reasonably be anticipated to cause or 
contribute to any impairment of visibility in any federal Class I 
area.
    \6\ A BART-eligible source is any one of the 26 specified source 
categories listed in appendix Y to 40 CFR part 51, Guidelines for 
BART Determinations Under the Regional Haze Rule.
    \7\ SO2 and NOX are considered the most 
significant visibility impairing pollutants.
    \8\ 40 CFR 51.308(e)(1).
---------------------------------------------------------------------------

    In a 2005 revision to the Regional Haze Rule,\9\ EPA demonstrated 
that CAIR \10\ would achieve greater reasonable progress than BART. 
This is often referred to as the CAIR-better-than-BART determination. 
Based on this determination, EPA amended its regulations so that states 
participating in the CAIR cap-and trade programs under 40 CFR part 96 
pursuant to an EPA approved CAIR SIP, or states that remain subject to 
a CAIR federal trading program under 40 CFR part 97, need not require 
affected BART-eligible electric generating units (EGUs) to install, 
operate, and maintain BART for emissions of SO2 and 
NOX. See 40 CFR 51.308(e)(4). Several states subject to 
CAIR, including West Virginia, relied on the CAIR cap-and-trade 
programs as an alternative to BART to achieve greater reasonable 
progress towards national visibility goals for their first SIP revision 
submitted to address regional haze.\11\
---------------------------------------------------------------------------

    \9\ 70 FR 39104 (July 6, 2005).
    \10\ CAIR involved the District of Columbia and 27 eastern 
states, including West Virginia, in several regional cap and trade 
programs to reduce SO2 and NOX emissions that 
contribute to the nonattainment or interfere with the maintenance of 
the 1997 ozone and PM2.5 NAAQS. 70 FR 25162 (May 12, 
2005).
    \11\ West Virginia submitted a comprehensive regional haze SIP 
revision on June 18, 2008.
---------------------------------------------------------------------------

    In July 2008, the United States Court of Appeals for the District 
of Columbia Circuit (D.C. Circuit) vacated CAIR.\12\ In December 2008, 
the D.C. Circuit remanded CAIR back to EPA without vacatur while a 
replacement rule consistent with the Court's opinion was developed.\13\ 
On August 8, 2011 (76 FR 48208), EPA promulgated CSAPR to replace CAIR 
and issued federal trading programs to implement the rule in the

[[Page 27736]]

states subject to CSAPR.\14\ CSAPR was to become effective January 1, 
2012; however, as discussed later, the timing of CSAPR's implementation 
was impacted by a number of court actions.
---------------------------------------------------------------------------

    \12\ North Carolina v. EPA, 531 F.3d 896 (D.C. Cir. 2008).
    \13\ North Carolina v. EPA, 550 F.3d 1176 (D.C. Cir. 2008).
    \14\ CSAPR is a regional cap-and-trade program meant to replace 
CAIR. Similar to CAIR, it is focused on eastern states (including 
West Virginia) and requires participants to limit their statewide 
emissions of SO2 and/or NOX in order to 
mitigate transported air pollution unlawfully impacting another 
state's ability to attain or maintain the following NAAQS: 1997 
ozone and PM2.5 NAAQS, the 2006 PM2.5 NAAQS, 
and the 2008 ozone NAAQS.
---------------------------------------------------------------------------

    After promulgating CSAPR, EPA conducted a technical analysis to 
determine whether compliance with CSAPR would satisfy the requirements 
of the Regional Haze Rule addressing alternatives to BART. In a June 7, 
2012 action, EPA amended the Regional Haze Rule to provide that 
participation by a state's EGUs in a CSAPR trading program for a given 
pollutant--either a CSAPR federal trading program or an integrated 
CSAPR state trading program implemented through an approved CSAPR SIP 
revision--qualifies as a BART alternative for those EGUs for that 
pollutant.\15\ See 40 CFR 51.308(e)(4). Since EPA promulgated this 
amendment, both states and EPA have relied on the CSAPR-better-than-
BART determination to satisfy the BART requirements for states that 
participate in CSAPR.\16\
---------------------------------------------------------------------------

    \15\ 77 FR 33656 (June 7, 2012).
    \16\ The D.C. Circuit recently upheld EPA's CSAPR-better-than-
BART determination. See Utility Air Regulatory Group v. EPA, No. 12-
1342 (D.C. Cir. March 20, 2018).
---------------------------------------------------------------------------

    Numerous parties filed petitions for review of CSAPR in the D.C. 
Circuit, and on August 21, 2012, the court issued its ruling, vacating 
and remanding CSAPR to EPA and ordering continued implementation of 
CAIR.\17\ The D.C. Circuit's vacatur of CSAPR was reversed by the 
United States Supreme Court on April 29, 2014, and the case was 
remanded to the D.C. Circuit to resolve remaining issues in accordance 
with the high court's ruling.\18\ On remand, the D.C. Circuit affirmed 
CSAPR in most respects, but invalidated without vacating some of the 
CSAPR budgets to a number of states.\19\ The remanded budgets included 
the Phase 2 SO2 emissions budgets for four states and the 
Phase 2 ozone-season NOX budgets for 11 states, including 
those for West Virginia. The D.C. Circuit litigation ultimately delayed 
implementation of CSAPR for three years, from January 1, 2012, when 
CSAPR's cap-and-trade programs were originally scheduled to replace the 
CAIR cap-and-trade programs, to January 1, 2015.\20\ Thus, the rule's 
Phase 2 budgets that were originally promulgated to begin on January 1, 
2014 began on January 1, 2017 instead. EPA has now taken all actions 
necessary to respond to the D.C. Circuit's remand of the various CSAPR 
budgets. On September 29, 2017, EPA finalized a determination that the 
changes to the scope of CSAPR coverage following the remand of certain 
of the budgets by the D.C. Circuit do not alter EPA's conclusion that 
CSAPR remains better-than-BART. In sum, EGU participation in a CSAPR 
trading program remains available as an alternative to BART for states 
participating in CSAPR.

    \20\ Following the April 2014 Supreme Court decision, EPA filed 
a motion asking the D.C. Circuit to delay, by three years, all CSAPR 
compliance deadlines that had not passed as of the approval date of 
the stay on CSAPR. On October 23, 2014, the D.C. Circuit granted 
EPA's request, and on December 3, 2014 (79 FR 71663), in an interim 
final rule, EPA set the updated effective date of CSAPR as January 
1, 2015 and delayed the implementation of CSAPR Phase 1 to 2015 and 
CSAPR Phase 2 to 2017. In accordance with the interim final rule, 
the sunset date for CAIR was December 31, 2014, and EPA began 
implementing CSAPR on January 1, 2015.
---------------------------------------------------------------------------

B. Partial Regional Haze Federal Implementation Plan

    On March 23, 2012, EPA finalized a limited approval and a limited 
disapproval of a SIP revision submitted by WVDEP on June 18, 2008 
addressing regional haze program requirements.\21\ The limited 
disapproval of this SIP revision was based upon West Virginia's 
reliance on CAIR as an alternative to BART and as a measure for 
reasonable progress. On June 7, 2012, EPA finalized a determination 
that for states covered by CSAPR, including West Virginia, CSAPR 
achieves greater reasonable progress towards the national visibility 
goals in Class I areas than source-specific BART. In this same June 7, 
2012 action, EPA also promulgated FIPs that replaced reliance on CAIR 
with reliance on CSAPR to meet BART and reasonable progress 
requirements, to address deficiencies in CAIR-dependent regional haze 
SIPs for several states, including West Virginia.\22\ Consequently, for 
West Virginia and other states, this particular aspect of their 
regional haze requirements was satisfied by EPA's issuance of a FIP 
(hereafter referred to as partial RH FIP).
---------------------------------------------------------------------------

    \21\ 77 FR 16937 (March 23, 2012).
    \22\ 77 FR 33643 (June 7, 2012).
---------------------------------------------------------------------------

    On September 16, 2015, the State of West Virginia submitted a 
revision to its Regional Haze SIP to change its present reliance from 
CAIR to CSAPR for the purpose of meeting BART for regional haze and 
addressing reasonable progress requirements, thereby eliminating West 
Virginia's need for the partial RH FIP. The SIP revision was also 
submitted to meet outstanding visibility protection requirements under 
section 110(a)(2)(D)(i)(II) of the CAA for the 2010 SO2 
NAAQS.

C. Section 110(a)(2)(D)(i)(II) Prong 4 Requirement

    The CAA requires states to submit, within three years after 
promulgation of a new or revised NAAQS, SIP revisions meeting the 
applicable elements of sections 110(a)(1) and (2). SIP revisions that 
are intended to meet the requirements of section 110(a) of the CAA are 
often referred to as infrastructure SIPs and the elements under 110(a) 
are referred to as infrastructure requirements. Several of these 
applicable elements are delineated within section 110(a)(2)(D)(i) of 
the CAA. Section 110(a)(2)(D)(i) requires SIPs to contain adequate 
provisions to prohibit emissions in that state from having certain 
adverse air quality effects on neighboring states due to interstate 
transport of air pollution. There are four prongs within section 
110(a)(2)(D)(i) of the CAA; section 110(a)(2)(D)(i)(I) contains prongs 
1 and 2, while section 110(a)(2)(D)(i)(II) includes prongs 3 and 4. 
This rulemaking action addresses prong 4 which is related to 
interference with measures by another state to protect visibility. 
Prong 4 requires that a state's SIP include adequate provisions 
prohibiting any source or other type of emissions activity in one state 
from interfering with measures to protect visibility required to be 
included in another state's SIP. One way in which prong 4 can be 
satisfied is if a state has a fully approved regional haze program 
within its SIP.\23\

(SIP) Elements under Clean Air Act Sections 110(a)(1) and 
110(a)(2),'' Memorandum from Stephen D. Page, September 13, 2013.
---------------------------------------------------------------------------

    As part of its September 16, 2015 SIP submittal, which is the 
subject of this rulemaking action, West Virginia demonstrates it should 
receive full approval of its regional haze SIP with the switch to 
reliance upon CSAPR and requests amending the portion of its October 
16, 2014 infrastructure SIP submission for the 2010 SO2 
NAAQS to address the prong 4 requirement for visibility protection for 
this NAAQS. West Virginia's infrastructure SIP revision submittal for 
the 2012 PM2.5 NAAQS, submitted to EPA subsequently on May 
12, 2017, refers to the

[[Page 27737]]

September 16, 2015 SIP submittal to address prong 4 for visibility 
protection for the 2012 PM2.5 NAAQS. Because West Virginia 
did not have a fully approved regional haze program at the time EPA 
took action to approve the infrastructure SIPs for the 2010 
SO2 and 2012 PM2.5 NAAQS, EPA determined that it 
would take separate action on the prong 4 portions of the October 16, 
2014 SIP submission for the 2010 SO2 NAAQS and of the May 
12, 2017 SIP submission for the 2012 PM2.5 NAAQS, at a later 
date.\24\

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

II. Summary of SIP Revision and EPA Analysis

    West Virginia submitted a SIP revision on September 16, 2015 to 
correct its regional haze and visibility protection deficiencies. West 
Virginia submitted the September 16, 2015 SIP revision seeking to 
correct the deficiencies identified in EPA's July 13, 2011 limited 
disapproval action, by replacing reliance on CAIR with reliance on 
CSAPR in its regional haze SIP.\25\ Specifically, the September 16, 
2015 submittal changes the West Virginia regional haze program to state 
that West Virginia is relying on CSAPR in its regional haze SIP to meet 
the BART and reasonable progress requirements to support visibility 
improvement progress goals for West Virginia's Class I areas, Dolly 
Sods and Otter Creek Wilderness Areas.
---------------------------------------------------------------------------

    \25\ West Virginia was included in the CSAPR federal trading 
programs on August 8, 2011. 76 FR 48208.
---------------------------------------------------------------------------

    Additionally, the September 16, 2015 submittal revises the prong 4 
portion of the infrastructure SIP revision for the 2010 SO2 
NAAQS, which had been submitted on October 16, 2014, to address this 
visibility protection requirement in CAA section 110(a)(2)(D)(i)(II). 
At the time of this SIP submittal, West Virginia did not have a fully 
approved regional haze program as the Agency had issued a limited 
disapproval of the State's regional haze plan on July 13, 2011, due to 
its reliance on CAIR. Subsequently, West Virginia submitted to EPA on 
May 12, 2017 a SIP revision regarding the infrastructure requirements 
in CAA section 110(a)(2) for the 2012 PM2.5 NAAQS. In order 
to meet prong 4 for the 2012 PM2.5 NAAQS, this May 12, 2017 
submittal referred to West Virginia's September 16, 2015 regional haze 
SIP submittal to address the prong 4 requirement in CAA section 
110(a)(2)(D)(i)(II).
    The State's September 16, 2015 regional haze SIP revision replaces 
reliance upon CAIR for reliance upon CSAPR to address the deficiencies 
identified in EPA's limited disapproval of West Virginia's regional 
haze SIP.\26\ EPA is proposing to find that this revision would satisfy 
the NOX and SO2 BART and reasonable progress 
requirements for EGUs in West Virginia and therefore make West 
Virginia's regional haze program fully approvable. Upon EPA's final 
approval of this SIP, West Virginia will have a SIP in place to address 
all of its regional haze requirements. Therefore, EPA is proposing to 
find that West Virginia's reliance in its SIP upon CSAPR for certain 
BART and reasonable progress requirements is in accordance with the CAA 
and Regional Haze Rule requirements (including 40 CFR 51.308(e)(2)) as 
EPA has recently affirmed that CSAPR remains better-than-BART for 
regional haze requirements.\27\ Because West Virginia's approved 
regional haze SIP will address EGU BART and reasonable progress 
requirements upon final approval of the September 16, 2015 SIP 
submission, EPA is proposing to convert the Agency's prior limited 
disapproval/limited approval of West Virginia's regional haze SIP to a 
full approval. EPA is also proposing to remove EPA's June 7, 2012 
partial RH FIP for West Virginia, which replaced reliance on CAIR with 
reliance on CSAPR to address the previously deficient regional haze 
requirements. Additionally, EPA is proposing to approve the prong 4 
portion of West Virginia's October 16, 2014 SIP submission, as revised 
by the September 16, 2015 regional haze submittal, for the 2010 
SO2 NAAQS and to approve the prong 4 portion of the May 12, 
2017 SIP submission for the 2012 PM2.5 NAAQS, which refers 
to the September 16, 2015 regional haze submittal, as the West Virginia 
SIP will now meet prong 4 visibility requirements of the CAA with a 
fully approved regional haze SIP.\28\
---------------------------------------------------------------------------

    \26\ In this respect, the September 16, 2015 SIP submission 
therefore mirrors the requirements from EPA's partial RH FIP for 
West Virginia.
    \27\ See 82 FR 45481 (September 29, 2017) (reaffirming CSAPR 
better-than-BART). See Utility Air Regulatory Group v. EPA, No. 12-
1342 (D.C. Cir. March 20, 2018) (upholding CSAPR as better-than-
BART).
    \28\ All other applicable infrastructure requirements under 
section 110(a)(2) for the West Virginia's infrastructure SIP 
submissions for the 2010 SO2 NAAQS and the 2012 
PM2.5 NAAQS have been or will be addressed in separate 
rulemakings.
---------------------------------------------------------------------------

III. Proposed Action

    EPA is proposing to take the following actions: (1) Approve West 
Virginia's September 16, 2015 SIP submission to change reliance on CAIR 
to reliance on CSAPR for certain elements of West Virginia's regional 
haze program; (2) convert EPA's limited approval/limited disapproval of 
West Virginia's regional haze program to a full approval; (3) approve 
West Virginia's October 16, 2014 SIP submission, as revised September 
16, 2015, as satisfying prong 4 regarding visibility protection for the 
2010 SO2 NAAQS; (4) approve West Virginia's May 12, 2017 
infrastructure SIP submission, referring to the September 16, 2015 
regional haze SIP submission, as satisfying prong 4 regarding 
visibility protection for the 2012 PM2.5 NAAQS; and (5) 
remove West Virginia's partial regional haze FIP which replaced certain 
regional haze requirements as these requirements will now be contained 
within the West Virginia regional haze SIP upon final approval of the 
September 16, 2015 SIP submittal. EPA is soliciting public comments on 
the issues discussed in this document. These comments will be 
considered before taking final action.

IV. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the 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 proposed 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 SIP approvals are exempted 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

[[Page 27738]]

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).
    In addition, this proposed rule, addressing West Virginia's 
regional haze requirements and visibility protection for the 2010 
SO2 and 2012 PM2.5 NAAQS and the withdrawal of 
the West Virginia regional haze regional FIP, 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. 
In addition, pursuant to CAA section 307(d)(1)(B), EPA proposes to 
determine that this action is subject to the provisions of section 
307(d). Section 307(d) establishes procedural requirements specific to 
certain rulemaking actions under the CAA. Furthermore, section 
307(d)(1)(V) of the CAA provides that the provisions of section 307(d) 
apply to ``such other actions as the Administrator may determine.'' EPA 
proposes that the provisions of 307(d) apply to EPA's action on the 
West Virginia SIP revision. The withdrawal of the provisions of the 
West Virginia regional haze regional FIP is subject to the requirements 
of CAA section 307(d), as it constitutes a revision to a FIP under 
section 110(c) of the CAA.
