Provisions the EPA Is Removing From
the SIP or From Incorporation by
Reference
Under the authority of CAA section
110(k)(6), we are removing the following
provisions from the SIP because they
implement other requirements of the
CAA and the State has not relied on
these provisions to demonstrate
attainment or maintenance of the
NAAQS or to meet other specific
requirements of section 110 of the CAA:
18 AAC 50.220(c)(1)(A), (B), (C) and 18
AAC 50.302(a)(3). We are also removing
AS 46.14.510(b), which was
incorporated by reference on November
18, 1998 (63 FR 63983). However, we
have determined that the provision is
addressed by incorporation by reference
elsewhere in the Federally-approved
SIP.

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, the
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
VerDate Mar<15>2010

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 Order 12866 (58 FR 51735,
October 4, 1993);
• 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 the requirements of
section 12(d) of the National
Technology Transfer and Advancement
Act of 1995 (15 U.S.C. 272 note) because
this action does not involve technical
standards; and
• does not provide the 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 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 the EPA notes
that it will not impose substantial direct
costs on tribal governments or preempt
tribal law.

Agency (EPA).
ACTION: Proposed rule.
AGENCY:
The Environmental Protection
Agency (EPA) is proposing to approve
the State of West Virginia’s request to
redesignate to attainment the West
Virginia portion of the MartinsburgHagerstown, WV-MD nonattainment
area (Martinsburg Area or Area) for the
1997 annual fine particulate matter
(PM2.5) national ambient air quality
standard (NAAQS). EPA is also
proposing to determine that the
Martinsburg Area continues to attain the
1997 annual PM2.5 NAAQS. In addition,
EPA is proposing to approve as a
revision to the West Virginia State
Implementation Plan (SIP), the
associated maintenance plan to show
maintenance of the 1997 annual PM2.5
NAAQS through 2025 for the Area. The
maintenance plan includes the 2017 and
2025 PM2.5 and nitrogen oxides (NOX)
mobile vehicle emissions budgets
(MVEBs) for Berkeley County, West
Virginia for the 1997 annual PM2.5
NAAQS which EPA is proposing to
approve for transportation conformity
purposes. Furthermore, EPA is
proposing to approve as a revision to the
West Virginia SIP, the 2007 base year
emissions inventory for the Area for the
1997 annual PM2.5 NAAQS. These
actions are being taken under the Clean
Air Act (CAA).

I. Background
The first air quality standards for
PM2.5 were established on July 18, 1997
(62 FR 38652). EPA promulgated an
annual standard at a level of 15
micrograms per cubic meter (mg/m3),
based on a three-year average of annual
mean PM2.5 concentrations (the 1997
annual PM2.5 standard). In the same
rulemaking, EPA promulgated a 24-hour
standard of 65 mg/m3 based on a threeyear average of the 98th percentile of 24hour concentrations.
On January 5, 2005 (70 FR 944, 1014),
EPA published air quality area
designations for the 1997 PM2.5 NAAQS.
In that rulemaking action, EPA
designated the Martinsburg Area as
nonattainment for the 1997 annual
PM2.5 NAAQS. The Martinsburg Area is
comprised of Berkeley County in West
Virginia (the West Virginia portion of
the Area) and Washington County in
Maryland. See 40 CFR 81.321
(Maryland) and 40 CFR 81.349 (West
Virginia).
On October 17, 2006 (71 FR 61144),
EPA retained the annual average
standard at 15 mg/m3 but revised the 24hour standard to 35 mg/m3, based again
PO 00000
Frm 00009
Fmt 4702
Sfmt 4702
25541
on the three-year average of the 98th
percentile of the 24-hour concentrations
(the 2006 annual PM2.5 standard). On
November 13, 2009 (74 FR 58688), EPA
published designations for the 2006 24hour PM2.5 standard, which became
effective on December 14, 2009. In that
rulemaking action, EPA designated the
Martinsburg Area as attainment for the
2006 24-hour PM2.5 NAAQS. See 74 FR
58737 and 40 CFR 81.321 (Maryland)
and also see 74 FR 58775 and 40 CFR
81.349 (West Virginia).
In response to legal challenges of the
annual standard promulgated in 2006,
the D.C. Circuit Court remanded the
2006 annual standard to EPA for further
consideration. See American Farm
Bureau Federation and National Pork
Producers Council, et. al. v. EPA, 559
F.3d 512 (D.C. Cir. 2009). However,
given that the 1997 annual and the 2006
annual PM2.5 standards are essentially
identical, attainment of the 1997 annual
PM2.5 standard would also indicate
attainment of the remanded 2006 annual
PM2.5 standard. Since the Martinsburg
Area is designated nonattainment for
the annual NAAQS promulgated in
1997, today’s proposed rulemaking
action addresses the redesignation to
attainment only for this standard.
On November 20, 2009 (74 FR 60199),
EPA determined that the Martinsburg
Area had attained the 1997 annual PM2.5
NAAQS. Pursuant to 40 CFR 51.1004(c)
and based on this determination, the
requirements for the Martinsburg Area
to submit an attainment demonstration
and associated reasonably available
control measures (RACM), a reasonable
further progress (RFP) plan, contingency
measures, and other planning SIP
revisions related to the attainment of the
1997 annual PM2.5 NAAQS were
suspended until such time as: (1) The
Area is redesignated to attainment for
the standard, at which time the
requirements no longer apply; or (2)
EPA determines that the Area has again
violated the standard, at which time
such plans are required to be submitted.
On January 20, 2012 (77 FR 1411), EPA
also determined that the Martinsburg
Area had attained the 1997 annual PM2.5
NAAQS by the applicable date of April
5, 2010.
On August 5, 2013, the State of West
Virginia through the West Virginia
Department of Environmental Protection
(WVDEP) formally submitted a request
to redesignate the West Virginia portion
of the Martinsburg Area from
nonattainment to attainment for the
1997 annual PM2.5 NAAQS.
Concurrently, WVDEP submitted a
maintenance plan for the Area as a SIP
revision to ensure continued attainment
throughout the Area over the next 10

years. The maintenance plan also
includes a 2007 base year emissions
inventory for PM2.5, NOX, sulfur dioxide
(SO2), volatile organic compounds
(VOC) and ammonia (NH3) for the1997
annual PM2.5 NAAQS in order to meet
the emissions inventory requirement of
section 172(c)(3) of the CAA. In
addition, the maintenance plan includes
the 2017 and 2025 PM2.5 and NOX
MVEBs used for transportation
conformity purposes for Berkeley
County, West Virginia for the 1997
annual PM2.5 NAAQS.
In this proposed rulemaking action,
EPA takes into account two decisions of
the United States Court of Appeals for
the District of Columbia (D.C. Circuit
Court). In the first of the two D.C.
Circuit Court decisions, the D.C. Circuit
Court, on August 21, 2012, issued EME
Homer City Generation, L.P. v. EPA, 696
F.3d 7 (D.C. Cir. 2012), which vacated
and remanded the Cross-State Air
Pollution Control Rule (CSAPR) and
ordered EPA to continue administering
the Clean Air Interstate Rule (CAIR)
‘‘pending . . . development of a valid
replacement.’’ EME Homer City at 38.
The D.C. Circuit Court denied all
petitions for rehearing on January 24,
2013. EPA and other parties filed for
certiorari to the Supreme Court, and on
June 24, 2013, the Supreme Court
granted certiorari on EPA’s petition for
appeal of EME Homer City Generation.
See EME Homer City Generation, L.P. v.
EPA, 696 F.3d 7 (D.C. Cir. 2012), cert.
granted, 570 U.S.—(2013). Nonetheless,
EPA intends to continue to act in
accordance with the EME Homer City
opinion. In the second decision, on
January 4, 2013, in Natural Resources
Defense Council (NRDC) v. EPA, the
D.C. Circuit Court remanded to EPA the
‘‘Final Clean Air Fine Particle
Implementation Rule’’ (72 FR 20586,
April 25, 2007) and the
‘‘Implementation of the New Source
Review (NSR) Program for Particulate
Matter Less than 2.5 Micrometers
(PM2.5)’’ final rule (73 FR 28321, May
16, 2008). 706 F.3d 428 (D.C. Cir. 2013).

II. EPA’s Requirements
A. Criteria for Redesignation to
Attainment
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) EPA
determines that the area has attained the
applicable NAAQS; (2) EPA has fully
approved the applicable
implementation plan for the area under
section 110(k) of the CAA; (3) EPA
determines that the improvement in air
VerDate Mar<15>2010
15:41 May 02, 2014
Jkt 232001
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) EPA has fully approved a
maintenance plan for the area as
meeting the requirements of section
175A of the CAA; and (5) the state
containing such area has met all
requirements applicable to the area
under section 110 and part D of the
CAA. Each of these requirements are
discussed in section V. of today’s
proposed rulemaking action.
EPA has provided guidance on
redesignation in the ‘‘SIPs; General
Preamble for the Implementation of
Title I of the CAA Amendments of
1990,’’ (57 FR 13498, April 16, 1992)
(the ‘‘General Preamble’’) and has
provided further guidance on processing
redesignation requests in the following
documents: (1) ‘‘Procedures for
Processing Requests to Redesignate
Areas to Attainment,’’ Memorandum
from John Calcagni, Director, Air
Quality Management Division,
September 4, 1992 (hereafter referred to
as the ‘‘1992 Calcagni Memorandum’’);
(2) ‘‘SIP Actions Submitted in Response
to CAA Deadlines,’’ Memorandum from
John Calcagni, Director, Air Quality
Management Division, October 28, 1992;
and (3) ‘‘Part D New Source Review
(Part D NSR) Requirements for Areas
Requesting Redesignation to
Attainment,’’ Memorandum from Mary
D. Nichols, Assistant Administrator for
Air and Radiation, October 14, 1994.
B. Requirements of 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 of the CAA, the plan must
demonstrate continued attainment of
the applicable NAAQS for at least 10
years after approval of a redesignation of
an area 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 such
contingency measures, with a schedule
for implementation, as EPA deems
necessary to assure prompt correction of
any future PM2.5 violations.
The 1992 Calcagni Memorandum
provides additional guidance on the
content of a maintenance plan. The
memorandum states that a maintenance
PO 00000
Frm 00010
Fmt 4702
Sfmt 4702
plan should address the following
provisions: (1) An attainment emissions
inventory; (2) a maintenance
demonstration showing maintenance for
10 years; (3) a commitment to maintain
the existing monitoring network; (4)
verification of continued attainment;
and (5) a contingency plan to prevent or
correct future violations of the NAAQS.
Under the CAA, states are required to
submit, at various times, control strategy
SIP revisions and maintenance plans for
nonattainment areas and for areas
seeking redesignation to attainment for
a given NAAQS. These emission control
strategy SIP revisions (e.g., RFP and
attainment demonstration SIP revisions)
and maintenance plans create MVEBs
based on onroad mobile source
emissions for the relevant criteria
pollutants and/or their precursors,
where appropriate, to address pollution
from onroad transportation sources. The
MVEBs are the portions of the total
allowable emissions that are allocated to
onroad vehicle use that, together with
emissions from all other sources in the
area, will provide attainment, RFP, or
maintenance, as applicable. The budget
serves as a ceiling on emissions from an
area’s planned transportation system.
Under 40 CFR part 93, a MVEB for an
area seeking a redesignation to
attainment is established for the last
year of the maintenance plan.
The maintenance plan for the West
Virginia portion of the Martinsburg
Area, that comprises Berkeley County in
West Virginia, includes the 2017 and
2025 PM2.5 and NOX MVEBs for
transportation conformity purposes. The
transportation conformity determination
for the Area is further discussed in
section V.C. of today’s proposed
rulemaking action and a technical
support document (TSD) dated January
28, 2014, available on line at
www.regulations.gov, Docket ID No.
EPA–OAR–R03–2013–0690.
III. Summary of Proposed Actions
EPA is proposing to take several
rulemaking actions related to the
redesignation of the West Virginia
portion of the Martinsburg Area to
attainment for the 1997 annual PM2.5
NAAQS. EPA is proposing to find that
the Area meets the requirements for
redesignation for the 1997 annual PM2.5
NAAQS under section 107(d)(3)(E) of
the CAA. EPA is thus proposing to
approve West Virginia’s request to
change the legal definition for the West
Virginia portion of the Martinsburg Area
from nonattainment to attainment for
the 1997 annual PM2.5 NAAQS. This
action does not impact the legal
definition of the Maryland portion of
E:\FR\FM\05MYP1.SGM
05MYP1
Federal Register / Vol. 79, No. 86 / Monday, May 5, 2014 / Proposed Rules
the Area. EPA is taking separate action
to redesignate the Maryland portion.
EPA is also proposing to approve the
associated maintenance plan for the
West Virginia portion of the
Martinsburg Area as a revision to the
West Virginia SIP for the 1997 annual
PM2.5 NAAQS, including the 2017 and
2025 PM2.5 and NOX MVEBs of the Area.
The approval of the maintenance plan is
one of the CAA criteria for redesignation
of the Area to attainment for the 1997
annual PM2.5 NAAQS. West Virginia’s
maintenance plan is designed to ensure
continued attainment in the West
Virginia portion of the Martinsburg Area
for 10 years after redesignation for the
1997 annual PM2.5 NAAQS.
EPA previously determined that the
Martinsburg Area has attained the 1997
annual PM2.5 NAAQS. Therefore, EPA is
proposing to find that the Area
continues to attain the standard. See 74
FR 60199, November 20, 2009 and 77
FR 1411, January 10, 2012. EPA is also
proposing to approve the 2007
comprehensive emissions inventory that
includes PM2.5, SO2, NOX, VOC, and
NH3 for the West Virginia portion of the
Area as a revision to the West Virginia
SIP for the 1997 annual PM2.5 NAAQS
in order to meet the requirements of
section 172(c)(3) of the CAA. EPA’s
analysis of the proposed actions is
provided in section V. of today’s
proposed rulemaking action.
IV. Effects of Recent Court Decisions on
Proposed Actions
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS
A. Effect of the August 21, 2012 D.C.
Circuit Court Decision Regarding EPA’s
CSAPR
1. Background
EPA promulgated CSAPR (76 FR
48208, August 8, 2011), to replace CAIR,
which has been in place since 2005. See
76 FR 59517. CAIR requires significant
reductions in emissions of SO2 and NOX
from electric generating units (EGUs) to
limit the interstate transport of these
pollutants and the ozone and fine
particulate matter they form in the
atmosphere. See 76 FR 70093. The D.C.
Circuit Court 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 December 30, 2011, the D.C.
Circuit Court issued an order addressing
the status of CSAPR and CAIR in
response to motions filed by numerous
parties seeking a stay of CSAPR pending
judicial review. In that order, the D.C.
Circuit Court stayed CSAPR pending
VerDate Mar<15>2010
15:41 May 02, 2014
Jkt 232001
resolution of the petitions for review of
that rule in EME Homer City Generation,
L.P. v. EPA (No. 11–1302 and
consolidated cases). The D.C. Circuit
Court also indicated that EPA was
expected to continue to administer
CAIR in the interim until judicial
review of CSAPR was completed.
On August 21, 2012, the D.C. Circuit
Court issued a decision to vacate
CSAPR. In that decision, it also ordered
EPA to continue administering CAIR
‘‘pending the promulgation of a valid
replacement.’’ EME Homer City, 696
F.3d at 38 (D.C. Circ. 2012). The D.C.
Circuit Court denied all petitions for
rehearing on January 24, 2013. EPA and
other parties have filed petitions for
certiorari to the U.S. Supreme Court. On
June 24, 2013 the Supreme Court
granted EPA’s petition for certiorari.
Nonetheless, EPA intends to continue to
act in accordance with the EME Homer
City opinion.
2. Proposal on This Issue
In light of these unique circumstances
and for the reasons explained
subsequently, to the extent that
attainment is due to emission
reductions associated with CAIR, EPA is
here proposing to determine that those
reductions are sufficiently permanent
and enforceable for purposes of sections
107(d)(3)(E)(iii) and 175A of the CAA.
EPA, therefore, proposes to approve the
redesignation request and the related
SIP revisions for the West Virginia
portion of the Martinsburg Area
(Berkeley County, West Virginia),
including West Virginia’s plan for
maintaining attainment of the 1997
annual PM2.5 NAAQS in the Area.
As directed by the D.C. Circuit Court,
CAIR remains in place and enforceable
until substituted by a valid replacement
rule. West Virginia’s SIP revision lists
CAIR as a control measure that was
approved by EPA on August 6, 2009 (74
FR 38536) and became state-effective on
May 1, 2008 for the purpose of reducing
SO2 and NOX emissions. CAIR was thus
in place and getting emission reductions
when the Martinsburg Area monitored
attainment of the 1997 annual PM2.5
NAAQS. The quality-assured, qualitycontrolled, certified monitoring data
used to demonstrate the Area’s
attainment of the 1997 annual PM2.5
NAAQS was also impacted by CAIR.
To the extent that West Virginia is
relying on CAIR in its maintenance
plan, the recent directive from the D.C.
Circuit Court in EME Homer City
ensures that the reductions associated
with CAIR will be permanent and
enforceable for the necessary time
period. EPA has been ordered by the
D.C. Circuit Court to develop a new rule
PO 00000
Frm 00011
Fmt 4702
Sfmt 4702
25543
to address interstate transport to replace
CSAPR, and the opinion makes clear
that after promulgating that new rule,
EPA must provide states an opportunity
to draft and submit SIPs to implement
that rule. Thus, CAIR will remain in
place until: (1) EPA has promulgated a
final rule through a notice-and-comment
rulemaking process; (2) states have had
an opportunity to draft and submit SIPs;
(3) EPA has reviewed the SIPs to
determine if they can be approved; and
(4) EPA has taken action on the SIPs,
including promulgating a Federal
Implementation Plan (FIP) if
appropriate. The D.C. Circuit Court’s
clear instruction to EPA that it must
continue to administer CAIR until a
valid replacement exists provides an
additional backstop. By definition, any
rule that replaces CAIR and meets the
D.C. Circuit Court’s direction would
require upwind states to have SIPs that
eliminate significant contributions to
downwind nonattainment and prevent
interference with maintenance in
downwind areas.
Further, in vacating CSAPR and
requiring EPA to continue administering
CAIR, the D.C. Circuit Court
emphasized that the consequences of
vacating CAIR ‘‘might be more severe
now in light of the reliance interests
accumulated over the intervening four
years.’’ EME Homer City, 696 F.3d at 38.
The accumulated reliance interests
include the interests of states who
reasonably assumed they could rely on
reductions associated with CAIR which
brought certain nonattainment areas
into attainment with the NAAQS. If EPA
were prevented from relying on
reductions associated with CAIR in
redesignation actions, states would be
forced to impose additional, redundant
reductions on top of those achieved by
CAIR. EPA believes this is precisely the
type of irrational result the D.C. Circuit
Court sought to avoid by ordering EPA
to continue administering CAIR. For
these reasons also, EPA believes it is
appropriate to allow states to rely on
CAIR, and the existing emissions
reductions achieved by CAIR, as
sufficiently permanent and enforceable
for purposes such as redesignation.
Following promulgation of the
replacement rule, EPA will review SIP
revisions as appropriate to identify
whether there are any issues that need
to be addressed.

B. Effect of the January 4, 2013 D.C.
Circuit Court Decision Regarding PM2.5
Implementation Under Subpart 4 of Part
D of Title I of the CAA
1. Background
On January 4, 2013, in NRDC v. EPA,
the D.C. Circuit Court remanded to EPA
the ‘‘Final Clean Air Fine Particle
Implementation Rule’’ (72 FR 20586,
April 25, 2007) and the
‘‘Implementation of the NSR Program
for PM2.5’’ final rule (73 FR 28321, May
16, 2008) (collectively, ‘‘1997 PM2.5
Implementation Rule’’). 706 F.3d 428
(D.C. Cir. 2013). The D.C. Circuit Court
found that EPA erred in implementing
the 1997 annual PM2.5 NAAQS pursuant
to the general implementation
provisions of subpart 1 of Part D of Title
I of the CAA (subpart 1), rather than the
particulate-matter-specific provisions of
subpart 4 of Part D of Title I (subpart 4).
Prior to the January 4, 2013 decision,
the states had worked towards meeting
the air quality goals of the 1997 PM2.5
NAAQS in accordance with EPA
regulations and guidance derived from
subpart 1 of Part D of Title I of the CAA.
Subsequent to this decision, EPA took
this history into account and responded
to the D.C. Circuit Court’s remand by
proposing to set a new deadline for any
remaining submissions that may be
required for a moderate nonattainment
area that are due to the applicability of
subpart 4 of Part D of Title I of the CAA.
On November 21, 2013 (78 FR 69806),
EPA issued a proposed rule,
Identification of Nonattainment
Classification and Deadlines for
Submission of SIP Provisions for the
1997 PM2.5 NAAQS (the PM2.5 Subpart
4 Classification and Deadline Rule)
identifying the classification under
subpart 4 for areas currently designated
nonattainment for the 1997 PM2.5
standards, the deadlines for states to
submit NSR and attainment-related SIP
elements required for these areas
pursuant to subpart 4, and the EPA
guidance that is currently available
regarding subpart 4 requirements. If
finalized, this rule will set a deadline
for states to submit attainment plans
and meet other subpart 4 requirements.
The proposed rule identified December
31, 2014 as the deadline for the states
to submit any additional attainmentrelated SIP elements that may be needed
to meet the applicable requirements of
subpart 4 for areas currently designated
nonattainment for the 1997 PM2.5
NAAQS and to submit SIPs addressing
the nonattainment NSR requirements in
subpart 4. Since West Virginia
submitted a request to redesignate the
West Virginia portion of the
Martinsburg Area from nonattainment to

15:41 May 02, 2014
Jkt 232001
attainment on August 5, 2013 and the
proposed PM2.5 Subpart 4 Classification
and Deadline Rule identifies a
December 31, 2014 deadline, West
Virginia is not required at this time to
meet the applicable requirements of
subpart 4.
2. Proposal on This Issue
EPA is proposing to determine that
the D.C. Circuit Court’s January 4, 2013
decision does not prevent EPA from
redesignating the West Virginia portion
of the Martinsburg Area to attainment
for the 1997 annual PM2.5 NAAQS. Even
in light of the D.C. Circuit Court’s
decision, redesignation for this Area is
appropriate under the CAA and EPA’s
longstanding interpretations of the
CAA’s provisions regarding
redesignation. EPA first explains its
longstanding interpretation that
requirements that are imposed, or that
become due, after a complete
redesignation request is submitted for
an area that is attaining the standard, are
not applicable for purposes of
evaluating a redesignation request.
Second, EPA then shows that, even if
EPA applies the subpart 4 requirements
to the West Virginia redesignation
request and disregards the provisions of
its 1997 PM2.5 Implementation Rule
recently remanded by the D.C. Circuit
Court, the State’s request for
redesignation of the Area still qualifies
for approval. EPA’s discussion takes
into account the effect of the D.C.
Circuit Court’s ruling and EPA’s
proposed PM2.5 Subpart 4 Classification
and Deadline Rule on the Area’s
maintenance plan, which EPA views as
approvable when subpart 4
requirements are considered.
a. Applicable Requirements for
Purposes of Evaluating the
Redesignation Request
With respect to the 1997 PM2.5
Implementation Rule, the D.C. Circuit
Court’s January 4, 2013 ruling rejected
EPA’s reasons for implementing the
PM2.5 NAAQS solely in accordance with
the provisions of subpart 1, and
remanded that matter to EPA, so that it
could address implementation of the
1997 annual PM2.5 NAAQS under
subpart 4 of Part D of the CAA, in
addition to subpart 1. For the purposes
of evaluating West Virginia’s
redesignation request for the West
Virginia portion of the Martinsburg
Area, to the extent that implementation
under subpart 4 would impose
additional requirements for areas
designated nonattainment, EPA believes
that those requirements are not
‘‘applicable’’ for the purposes of section
107(d)(3)(E) of the CAA, and thus EPA
PO 00000
Frm 00012
Fmt 4702
Sfmt 4702
is not required to consider subpart 4
requirements with respect to the
redesignation of the West Virginia
portion of the Martinsburg Area. Under
its longstanding interpretation of the
CAA, EPA has interpreted section
107(d)(3)(E) to mean, as a threshold
matter, that the part D provisions which
are ‘‘applicable’’ and which must be
approved in order for EPA to
redesignate an area include only those
which came due prior to a state’s
submittal of a complete redesignation
request. See 1992 Calcagni
Memorandum. See also ‘‘SIP
Requirements for Areas Submitting
Requests for Redesignation to
Attainment of the Ozone and Carbon
Monoxide (CO) NAAQS on or after
November 15, 1992,’’ Memorandum

Administrator, Air and Radiation,
September 17, 1993 (Shapiro
memorandum); Final Redesignation of
Detroit-Ann Arbor, (60 FR 12459,
12465–66, March 7, 1995); Final
Redesignation of St. Louis, Missouri, (68
FR 25418, 25424–27, May 12, 2003);
Sierra Club v. EPA, 375 F.3d 537, 541
(7th Cir. 2004) (upholding EPA’s
redesignation rulemaking applying this
interpretation and expressly rejecting
Sierra Club’s view that the meaning of
‘‘applicable’’ under the statute is
‘‘whatever should have been in the plan
at the time of attainment rather than
whatever actually was in the plan and
already implemented or due at the time
of attainment’’).1 In this case, at the time
that West Virginia submitted its
redesignation request for the 1997 PM2.5
NAAQS, the requirements under
subpart 4 were not due.
EPA’s view that, for purposes of
evaluating the redesignation of the West
Virginia portion of the Martinsburg
Area, the subpart 4 requirements were
not due at the time West Virginia
submitted the redesignation request is
in keeping with the EPA’s interpretation
of subpart 2 requirements for subpart 1
ozone areas redesignated subsequent to
the D.C. Circuit Court’s decision in
South Coast Air Quality Mgmt. Dist. v.
EPA, 472 F.3d 882 (D.C. Cir. 2006). In
South Coast, the D.C. Circuit Court
found that EPA was not permitted to
implement the 1997 8-hour ozone
standard solely under subpart 1, and
held that EPA was required under the
statute to implement the standard under
the ozone-specific requirements of
subpart 2 as well. Subsequent to the
1 Applicable requirements of the CAA that come
due subsequent to the area’s submittal of a complete
redesignation request remain applicable until a
redesignation is approved, but are not required as
a prerequisite to redesignation. Section 175A(c) of

wreier-aviles on DSK5TPTVN1PROD with PROPOSALS
Federal Register / Vol. 79, No. 86 / Monday, May 5, 2014 / Proposed Rules
South Coast decision, in evaluating and
acting upon redesignation requests for
the 1997 8-hour ozone standard that
were submitted to EPA for areas under
subpart 1, EPA applied its longstanding
interpretation of the CAA that
‘‘applicable requirements,’’ for purposes
of evaluating a redesignation, are those
that had been due at the time the
redesignation request was submitted.
See, e.g., Proposed Redesignation of
Manitowoc County and Door County
Nonattainment Areas (75 FR 22047,
22050, April 27, 2010). In those
rulemaking actions, EPA therefore, did
not consider subpart 2 requirements to
be ‘‘applicable’’ for the purposes of
evaluating whether the area should be
redesignated under section 107(d)(3)(E)
of the CAA.
EPA’s interpretation derives from the
provisions of section 107(d)(3) of the
CAA. Section 107(d)(3)(E)(v) states that,
for an area to be redesignated, a state
must meet ‘‘all requirements
‘applicable’ to the area under section
110 and part D.’’ Section 107(d)(3)(E)(ii)
provides that EPA must have fully
approved the ‘‘applicable’’ SIP for the
area seeking redesignation. These two
sections read together support EPA’s
interpretation of ‘‘applicable’’ as only
those requirements that came due prior
to submission of a complete
redesignation request.
First, holding states to an ongoing
obligation to adopt new CAA
requirements that arose after the state
submitted its redesignation request, in
order to be redesignated, would make it
problematic or impossible for EPA to act
on redesignation requests in accordance
with the 18-month deadline Congress
set for EPA action in section
107(d)(3)(D). If ‘‘applicable
requirements’’ were interpreted to be a
continuing flow of requirements with no
reasonable limitation, states, after
submitting a redesignation request,
would be forced continuously to make
additional SIP submissions that in turn
would require EPA to undertake further
notice-and-comment rulemaking actions
to act on those submissions. This would
create a regime of unceasing rulemaking
that would delay action on the
redesignation request beyond the 18month timeframe provided by the CAA
for this purpose.
Second, a fundamental premise for
redesignating a nonattainment area to
attainment is that the area has attained
the relevant NAAQS due to emission
reductions from existing controls. Thus,
an area for which a redesignation
request has been submitted would have
already attained the NAAQS as a result
of satisfying statutory requirements that
came due prior to the submission of the
VerDate Mar<15>2010
15:41 May 02, 2014
Jkt 232001
request. Absent a showing that
unadopted and unimplemented
requirements are necessary for future
maintenance, it is reasonable to view
the requirements applicable for
purposes of evaluating the redesignation
request as including only those SIP
requirements that have already come
due. These are the requirements that led
to attainment of the NAAQS. To require,
for redesignation approval, that a state
also satisfy additional SIP requirements
coming due after the state submits its
complete redesignation request, and
while EPA is reviewing it, would
compel the state to do more than is
necessary to attain the NAAQS, without
a showing that the additional
requirements are necessary for
maintenance.
In the context of this redesignation,
the timing and nature of the D.C. Circuit
Court’s January 4, 2013 decision in
NRDC v. EPA and EPA’s November 21,
2013 proposed PM2.5 Subpart 4
Classification and Deadline Rule,
compound the consequences of
imposing requirements that come due
after the redesignation request is
submitted. West Virginia submitted its
redesignation request for the 1997
annual PM2.5 NAAQS on August 5, 2013
for the West Virginia portion of the
Martinsburg Area, which is prior to the
deadline by which the Area is required
to meet the applicable requirements
pursuant to subpart 4.
To require West Virginia’s fullycompleted and pending redesignation
request for the 1997 annual PM2.5
NAAQS to comply now with
requirements of subpart 4 that the D.C.
Circuit Court announced only in
January 2013 and for which the
deadline to comply has not yet come,
would be to give retroactive effect to
such requirements and provide West
Virginia a unique and earlier deadline
for compliance solely on the basis of
submitting a redesignation request for
the West Virginia portion of the
Martinsburg Area. The D.C. Circuit
Court recognized the inequity of this
type of retroactive impact in Sierra Club
v. Whitman, 285 F.3d 63 (D.C. Cir.
2002),2 where it upheld the D.C. Circuit
Court’s ruling refusing to make
retroactive EPA’s determination that the
Area did not meet its attainment
deadline. In that case, petitioners urged

the D.C. Circuit Court to make EPA’s
nonattainment determination effective
as of the date that the statute required,
rather than the later date on which EPA
actually made the determination. The
D.C. Circuit Court rejected this view,
stating that applying it ‘‘would likely
impose large costs on States, which
would face fines and suits for not
implementing air pollution prevention
plans . . . even though they were not on
notice at the time.’’ Id. at 68. Similarly,
it would be unreasonable to penalize the
State of West Virginia by rejecting its
redesignation request for an area that is
already attaining the 1997 annual PM2.5
NAAQS and that met all applicable
requirements known to be in effect at
the time of the requests. For EPA now
to reject the redesignation request solely
because West Virginia did not expressly
address subpart 4 requirements which
have not yet come due and for which it
had little to no notice, would inflict the
same unfairness condemned by the D.C.
Circuit Court in Sierra Club v. Whitman.
b. Subpart 4 Requirements and West
Virginia Redesignation Request
Even if EPA were to take the view that
the D.C. Circuit Court’s January 4, 2013
decision requires that, in the context of
pending redesignations for the 1997
annual PM2.5 NAAQS, subpart 4
requirements were due and in effect at
the time West Virginia submitted its
redesignation request, EPA proposes to
determine that the West Virginia portion
of the Martinsburg Area still qualifies
for redesignation to attainment for the
1997 annual PM2.5 NAAQS. As
explained subsequently, EPA believes
that the redesignation request for the
West Virginia portion of the
Martinsburg Area, though not expressed
in terms of subpart 4 requirements,
substantively meets the requirements of
that subpart for purposes of
redesignating the Area to attainment for
the 1997 annual PM2.5 NAAQS.
With respect to evaluating the
relevant substantive requirements of
subpart 4 for purposes of redesignating
the West Virginia portion of the
Martinsburg Area, EPA notes that
subpart 4 incorporates components of
subpart 1 of part D, which contains
general air quality planning
requirements for areas designated as
nonattainment. See section 172(c).
Subpart 4 itself contains specific
planning and scheduling requirements
for coarse particulate matter (PM10) 3
nonattainment areas, and under the D.C.
Circuit Court’s January 4, 2013 decision
in NRDC v. EPA, these same statutory
3 PM
10 refers to particulates nominally 10
micrometers in diameter or smaller.

wreier-aviles on DSK5TPTVN1PROD with PROPOSALS
25546
Federal Register / Vol. 79, No. 86 / Monday, May 5, 2014 / Proposed Rules
requirements also apply for PM2.5
nonattainment areas. EPA has
longstanding general guidance that
interprets the 1990 amendments to the
CAA, making recommendations to states
for meeting the statutory requirements
for SIPs for nonattainment areas. See,
the General Preamble. In the General
Preamble, EPA discussed the
relationship of subpart 1 and subpart 4
SIP requirements, and pointed out that
subpart 1 requirements were to an
extent ‘‘subsumed by, or integrally
related to, the more specific PM10
requirements’’ (57 FR 13538, April 16,
1992). The subpart 1 requirements
include, among other things, provisions
for attainment demonstrations, RACM,
RFP, emissions inventories, and
contingency measures.
For the purposes of this redesignation
request, in order to identify any
additional requirements which would
apply under subpart 4, consistent with
EPA’s November 21, 2013 proposed
PM2.5 Subpart 4 Classification and
Deadline Rule, EPA is considering the
Martinsburg Area to be a ‘‘moderate’’
PM2.5 nonattainment area. As EPA
explained in its November 21, 2013
proposed rule, section 188 of the CAA
provides that all areas designated
nonattainment areas under subpart 4 are
initially classified by operation of law as
‘‘moderate’’ nonattainment areas, and
remain moderate nonattainment areas
unless and until EPA reclassifies the
area as a ‘‘serious’’ nonattainment area.
Accordingly, EPA believes that it is
appropriate to limit the evaluation of
the potential impact of subpart 4
requirements to those that would be
applicable to moderate nonattainment
areas. Sections 189(a) and (c) of subpart
4 apply to moderate nonattainment
areas and include the following: (1) An
approved permit program for
construction of new and modified major
stationary sources (section 189(a)(1)(A));
(2) an attainment demonstration (section
189(a)(1)(B)); (3) provisions for RACM
(section 189(a)(1)(C)); and (4)
quantitative milestones demonstrating
RFP toward attainment by the
applicable attainment date (section
189(c)).
The permit requirements of subpart 4,
as contained in section 189(a)(1)(A),
refer to and apply the subpart 1 permit
provisions requirements of sections 172
and 173 to PM10, without adding to
them. Consequently, EPA believes that
section 189(a)(1)(A) does not itself
impose for redesignation purposes any
additional requirements for moderate
areas beyond those contained in subpart
VerDate Mar<15>2010
15:41 May 02, 2014
Jkt 232001
1.4 In any event, in the context of
redesignation, EPA has long relied on
the interpretation that a fully approved
nonattainment NSR program is not
considered an applicable requirement
for redesignation, provided the area can
maintain the standard with a prevention
of significant deterioration (PSD)
program after redesignation. A 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 NSR Requirements for
Areas Requesting Redesignation to
Attainment.’’ See also rulemakings for
Detroit, Michigan (60 FR 12467–12468,
March 7, 1995); Cleveland-AkronLorain, Ohio (61 FR 20458, 20469–
20470, May 7, 1996); Louisville,
Kentucky (66 FR 53665, October 23,
2001); and Grand Rapids, Michigan (61
FR 31834–31837, June 21, 1996).
With respect to the specific
attainment planning requirements under
subpart 4,5 when EPA evaluates a
redesignation request under either
subpart 1 and/or 4, any area that is
attaining the PM2.5 NAAQS is viewed as
having satisfied the attainment planning
requirements for these subparts. For
redesignations, EPA has for many years
interpreted attainment-linked
requirements as not applicable for areas
attaining the standard. In the General
Preamble, EPA stated that: ‘‘The
requirements for RFP will not apply in
evaluating a request for redesignation to
attainment since, at a minimum, the air
quality data for the area must show that
the area has already attained. Showing
that the State will make RFP towards
attainment will, therefore, have no
meaning at that point.’’
The General Preamble also explained
that: ‘‘[t]he section 172(c)(9)
requirements are directed at ensuring
RFP and attainment by the applicable
date. These requirements no longer
apply when an area has attained the
standard and is eligible for
redesignation. Furthermore, section
175A for maintenance plans . . .
provides specific requirements for
contingency measures that effectively
supersede the requirements of section
172(c)(9) for these areas.’’ Id. EPA
similarly stated in its 1992 Calcagni
Memorandum that, ‘‘The requirements
for reasonable further progress and other
measures needed for attainment will not
apply for redesignations because they

only have meaning for areas not
attaining the standard.’’
It is evident that even if we were to
consider the D.C. Circuit Court’s January
4, 2013 decision in NRDC v. EPA to
mean that attainment-related
requirements specific to subpart 4
should be imposed retroactively 6 or
prior to December 13, 2014 and thus,
were due prior to West Virginia’s
redesignation request, those
requirements do not apply to an area
that is attaining the 1997 annual PM2.5
NAAQS, for the purpose of evaluating a
pending request to redesignate the area
to attainment. EPA has consistently
enunciated this interpretation of
applicable requirements under section
107(d)(3)(E) since the General Preamble
was published more than twenty years
ago. Courts have recognized the scope of
EPA’s authority to interpret ‘‘applicable
requirements’’ in the redesignation
context. See Sierra Club v. EPA, 375
F.3d 537 (7th Cir. 2004).
Moreover, even outside the context of
redesignations, EPA has viewed the
obligations to submit attainment-related
SIP planning requirements of subpart 4
as inapplicable for areas that EPA
determines are attaining the1997 annual
PM2.5 NAAQS. EPA’s prior ‘‘Clean Data
Policy’’ rulemakings for the PM10
NAAQS, also governed by the
requirements of subpart 4, explain
EPA’s reasoning. They describe the
effects of a determination of attainment
on the attainment-related SIP planning
requirements of subpart 4. See
‘‘Determination of Attainment for Coso
Junction Nonattainment Area,’’ (75 FR
27944, May 19, 2010). See also Coso
Junction Proposed PM10 Redesignation,
(75 FR 36023, 36027, June 24, 2010);
Proposed and Final Determinations of
Attainment for San Joaquin
Nonattainment Area (71 FR 40952,
40954–55, July 19, 2006; and 71 FR
63641, 63643–47, October 30, 2006). In
short, EPA in this context has also long
concluded that to require states to meet
superfluous SIP planning requirements
is not necessary and not required by the
CAA, so long as those areas continue to
attain the relevant NAAQS. Elsewhere
in this notice, EPA determined that the
Martinsburg Area has attained the 1997
annual PM2.5 NAAQS. Under its
longstanding interpretation, EPA is
proposing to determine here that the
West Virginia portion of the Area meets
the attainment-related plan
requirements of subparts 1 and 4 for the
1997 annual PM2.5 NAAQS. Thus, EPA
6 As EPA has explained above, we do not believe
that the D.C. Circuit Court’s January 4, 2013
decision should be interpreted so as to impose these
requirements on the states retroactively. Sierra Club

requirements to submit an attainment
demonstration under 189(a)(1)(B), a
RACM determination under section
172(c)(1) and section 189(a)(1)(c), a RFP
demonstration under 189(c)(1), and

under section 172(c)(9) are satisfied for
purposes of evaluating this
redesignation request.
c. Subpart 4 and Control of PM2.5
Precursors
The D.C. Circuit Court in NRDC v.
EPA remanded to EPA the two rules at
issue in the case with instructions to
EPA to re-promulgate them consistent
with the requirements of subpart 4. EPA
in this section addresses the D.C. Circuit
Court’s opinion with respect to PM2.5
precursors. While past implementation
of subpart 4 for PM10 has allowed for
control of PM10 precursors such as NOX
from major stationary, mobile, and area
sources in order to attain the standard
as expeditiously as practicable, section
189(e) of the CAA specifically provides
that control requirements for major
stationary sources of direct PM10 shall
also apply to PM10 precursors from
those sources, except where EPA
determines that major stationary sources
of such precursors ‘‘do not contribute
significantly to PM10 levels which
exceed the standard in the area.’’
EPA’s 1997 PM2.5 Implementation
Rule, remanded by the D.C. Circuit
Court, contained rebuttable
presumptions concerning certain PM2.5
precursors applicable to attainment
plans and control measures related to
those plans. Specifically, in 40 CFR
51.1002, EPA provided, among other
things, that a state was ‘‘not required to
address VOC [and NH3] as . . . PM2.5
attainment plan precursor[s] and to
evaluate sources of VOC [and NH3]
emissions in the State for control
measures.’’ EPA intended these to be
rebuttable presumptions. EPA
established these presumptions at the
time because of uncertainties regarding
the emission inventories for these
pollutants and the effectiveness of
specific control measures in various
regions of the country in reducing PM2.5
concentrations. EPA also left open the
possibility for such regulation of VOC
and NH3 in specific areas where that
was necessary.
The D.C. Circuit Court in its January
4, 2013 decision made reference to both
section 189(e) and 40 CFR 51.1002, and
stated that, ‘‘In light of our disposition,
we need not address the petitioners’
challenge to the presumptions in [40
CFR 51.1002] that VOCs and NH3 are
not PM2.5 precursors, as subpart 4
expressly governs precursor

Jkt 232001
presumptions.’’ NRDC v. EPA, at 27,
n.10.
Elsewhere in the D.C. Circuit Court’s
opinion, however, the D.C. Circuit Court
observed: ‘‘NH3 is a precursor to fine
particulate matter, making it a precursor
to both PM2.5 and PM10. For a PM10
nonattainment area governed by subpart
4, a precursor is presumptively
regulated. See 42 U.S.C. 7513a(e)
[section 189(e)].’’ Id. at 21, n.7.
For a number of reasons, EPA believes
that its proposed redesignation of the
West Virginia portion of the
Martinsburg Area for the 1997 annual
PM2.5 NAAQS are consistent with the
D.C. Circuit Court’s decision on this
aspect of subpart 4. First, while the D.C.
Circuit Court, citing section 189(e),
stated that ‘‘for a PM10 area governed by
subpart 4, a precursor is ‘presumptively’
regulated,’’ the D.C. Circuit Court
expressly declined to decide the specific
challenge to EPA’s 1997 PM2.5
Implementation Rule provisions
regarding NH3 and VOC as precursors.
The D.C. Circuit Court had no occasion
to reach whether and how it was
substantively necessary to regulate any
specific precursor in a particular PM2.5
nonattainment area, and did not address
what might be necessary for purposes of
acting upon a redesignation request.
However, even if EPA takes the view
that the requirements of subpart 4 were
deemed applicable at the time the state
submitted the redesignation request,
and disregards the 1997 PM2.5
Implementation Rule’s rebuttable
presumptions regarding NH3 and VOC
as PM2.5 precursors, the regulatory
consequence would be to consider the
need for regulation of all precursors
from any sources in the Area to
demonstrate attainment and to apply the
section 189(e) provisions to major
stationary sources of precursors. In the
case of the West Virginia portion of the
Martinsburg Area, EPA believes that
doing so is consistent with proposing
redesignation of the West Virginia
portion of the Area for the 1997 annual
PM2.5 NAAQS. The West Virginia
portion of the Area has attained the
1997 annual PM2.5 NAAQS without any
specific additional controls of NH3 and
VOC and emissions from any sources in
the Area.
Precursors in subpart 4 are
specifically regulated under the
provisions of section 189(e), which
requires, with important exceptions,
control requirements for major
stationary sources of PM10 precursors.7
7 Under either subpart 1 or subpart 4, for
purposes of demonstrating attainment as
expeditiously as practicable, a state is required to
evaluate all economically and technologically
PO 00000
Frm 00015
Fmt 4702
Sfmt 4702
25547
Under subpart 1 and EPA’s prior
implementation rule, all major
stationary sources of PM2.5 precursors
were subject to regulation, with the
exception of NH3 and VOC. Thus we
must address here whether additional
controls of NH3 and VOC from major
stationary sources are required under
section 189(e) of subpart 4 in order to
redesignate the Area for the 1997 annual
PM2.5 NAAQS. As explained
subsequently, we do not believe that
any additional controls of NH3 and VOC
are required in the context of this
redesignation.
In the General Preamble, EPA
discusses its approach to implementing
section 189(e). See 57 FR 13538–13542.
With regard to precursor regulation
under section 189(e), the General
Preamble explicitly stated that control
of VOC under other CAA requirements
may suffice to relieve a state from the
need to adopt precursor controls under
section 189(e). See 57 FR 13542. EPA in
this rulemaking action, proposes to
determine that West Virginia’s SIP has
met the provisions of section 189(e)
with respect to NH3 and VOC as
precursors. This proposed
determination is based on our findings
that: (1) The Martinsburg Area contains
no major stationary sources of NH3, and
(2) existing major stationary sources of
VOC are adequately controlled under
other provisions of the CAA regulating
the ozone NAAQS.8 In the alternative,
EPA proposes to determine that, under
the express exception provisions of
section 189(e), and in the context of the
redesignation of the West Virginia
portion of the Martinsburg Area, which
is attaining the 1997 annual PM2.5
NAAQS, at present NH3 and VOC
precursors from major stationary
sources do not contribute significantly
to levels exceeding the 1997 annual
PM2.5 NAAQS in the Area. See 57 FR
13539–42.
EPA notes that its 1997 PM2.5
Implementation Rule provisions in 40
CFR 51.1002 were not directed at
evaluation of PM2.5 precursors in the
context of redesignation, but at SIP
plans and control measures required to
bring a nonattainment area into
attainment of the 1997 annual PM2.5
NAAQS. By contrast, redesignation to
attainment primarily requires the
nonattainment area to have already
feasible control measures for direct PM emissions
and precursor emissions, and adopt those measures
that are deemed reasonably available.
8 The Martinsburg Area has reduced VOC
emissions through the implementation of various
control programs including VOC Reasonably
Available Control Technology (RACT) regulations
and various on-road and non-road motor vehicle
control programs.

attained due to permanent and
enforceable emission reductions, and to
demonstrate that controls in place can
continue to maintain the standard.
Thus, even if we regard the D.C. Circuit
Court’s January 4, 2013 decision as
calling for ‘‘presumptive regulation’’ of
NH3 and VOC for PM2.5 under the
attainment planning provisions of
subpart 4, those provisions in and of
themselves do not require additional
controls of these precursors for an area
that already qualifies for redesignation.
Nor does EPA believe that requiring
West Virginia to address precursors
differently than it has already would
result in a substantively different
outcome.
Although, as EPA has emphasized, its
consideration here of precursor
requirements under subpart 4 is in the
context of a redesignation to attainment,
EPA’s existing interpretation of subpart
4 requirements with respect to
precursors in attainment plans for PM10
contemplates that states may develop
attainment plans that regulate only
those precursors that are necessary for
purposes of attainment in the area in
question, i.e., states may determine that
only certain precursors need be
regulated for attainment and control
purposes.9 Courts have upheld this
approach to the requirements of subpart
4 for PM10.10 EPA believes that
application of this approach to PM2.5
precursors under subpart 4 is
reasonable. Because the Martinsburg
Area has already attained the 1997
annual PM2.5 NAAQS with its current
approach to regulation of PM2.5
precursors, EPA believes that it is
reasonable to conclude in the context of
this redesignation that there is no need
to revisit the attainment control strategy
with respect to the treatment of
precursors. Even if the D.C. Circuit
Court’s decision is construed to impose
an obligation, in evaluating this
redesignation request, to consider
additional precursors under subpart 4, it
would not affect EPA’s approval here of
West Virginia’s request for redesignation
of the Martinsburg Area for the 1997
9 See, e.g., ‘‘Approval and Promulgation of
Implementation Plans for California—San Joaquin
Valley PM10 Nonattainment Area; Serious Area Plan
for Nonattainment of the 24-Hour and Annual PM10
Standards,’’ (69 FR 30006, May 26, 2004)
(approving a PM10 attainment plan that impose
controls on direct PM10 and NOX emissions and did
not impose controls on SO2, VOC, or NH3
emissions).

annual PM2.5 NAAQS. In the context of
a redesignation, the Area has shown that
it has attained the standards. Moreover,
West Virginia has shown and EPA has
proposed to determine that attainment
of the 1997 annual PM2.5 NAAQS in this
Area is due to permanent and
enforceable emissions reductions on all
precursors necessary to provide for
continued attainment of the standards.
It follows logically that no further
control of additional precursors is
necessary. Accordingly, EPA does not
view the January 4, 2013 decision of the
D.C. Circuit Court as precluding
redesignation of the West Virginia
portion of the Martinsburg Area to
attainment for the 1997 annual PM2.5
NAAQS at this time.
In summary, even if, prior to the date
of the redesignation request submittal,
West Virginia was required to address
precursors for the Martinsburg Area
under subpart 4 rather than under
subpart 1, as interpreted in EPA’s
remanded 1997 PM2.5 Implementation
Rule, EPA would still conclude that the
West Virginia portion of the
Martinsburg Area had met all applicable
requirements for purposes of
redesignation in accordance with
section 107(d)(3)(E)(ii) and (v) of the
CAA.
V. EPA’s Analysis of West Virginia’s
SIP Submittal
EPA is proposing several rulemaking
actions for the West Virginia portion of
the Martinsburg Area: (1) To redesignate
the Area to attainment for the 1997
annual PM2.5 NAAQS; (2) to approve
into the West Virginia SIP, the
associated maintenance plan for the
1997 annual PM2.5 NAAQS; and (3) to
approve the 2007 comprehensive
emissions inventory into the West
Virginia SIP to satisfy section 172(c)(3)
of the CAA requirement for the Area,
one of the criteria for redesignation.
EPA’s proposed approvals of the
redesignation request and maintenance
plan for the 1997 annual PM2.5 NAAQS
are based upon EPA’s determination
that the Area continues to attain the
1997 annual PM2.5 NAAQS, which EPA
is proposing in this rulemaking action,
and that all other redesignation criteria
have been met for the West Virginia
portion of the Area. In addition, EPA is
proposing to approve the 2017 and 2025
MVEBs for Berkeley County, West
Virginia for transportation conformity
purposes. The following is a description
of how the West Virginia’s August 5,
PO 00000
Frm 00016
Fmt 4702
Sfmt 4702
2013 submittal satisfies the
requirements of section 107(d)(3)(E) of
the CAA for the 1997 annual PM2.5
NAAQS.
A. Redesignation Request
1. Attainment
As noted previously, in the final
rulemaking action dated January 10,
2012 (77 FR 1411), EPA determined that
the entire Martinsburg Area had
attained the 1997 annual PM2.5 NAAQS.
This determination of attainment was
based upon complete, quality-assured
and certified ambient air quality
monitoring data for the period of 2007–
2009 showing that the Area had attained
the 1997 annual PM2.5 NAAQS by its
applicable attainment date of April 5,
2010. On November 20, 2009 (74 FR
60199), EPA determined that the
Martinsburg Area had clean data for the
1997 annual PM2.5 NAAQS. The
determination was based upon
complete, quality assured, and certified
ambient air monitoring date showing
that this Area has monitored attainment
of the 1997 annual PM2.5 NAAQS based
on the 2006–2008 data and data
available to date for 2012 in EPA’s Air
Quality System (AQS) database. Further
discussion of pertinent air quality issues
underlying this determination was
provided in the notice of proposed
rulemaking for EPA’s determination of
attainment for this Area, published on
September 29, 2009 (74 FR 49833) for
the 1997 annual PM2.5 NAAQS.
EPA has reviewed the ambient air
quality PM2.5 monitoring data in the
Martinsburg Area consistent with the
requirements contained at 40 CFR part
50, and recorded in EPA’s AQS
database. To support the previous
determinations of attainment of the
Area, EPA has also reviewed more
recent data in its AQS database,
including certified, quality-assured data
for the period from 2008–2010, 2009–
2011 and 2010–2012. This data, shown
in Table 1, shows that the Martinsburg
Area continues to attain the 1997 annual
PM2.5 NAAQS. In addition, as discussed
subsequently with respect to the
maintenance plan, WVDEP has
committed to continue monitoring
ambient PM2.5 concentrations in
accordance with 40 CFR part 58. Thus,
EPA is proposing to determine that the
Martinsburg Area continues to attain the
1997 PM2.5 NAAQS.

2. The Area Has Met All Applicable
Requirements Under Section 110 and
Subpart 1 of the CAA and Has a Fully
Approved SIP Under Section 110(k) of
the CAA
In accordance with section
107(d)(3)(E)(v) of the CAA, the SIP
revisions for the 1997 annual PM2.5
NAAQS for the West Virginia portion of
the Martinsburg Area must be fully
approved under section 110(k) of the
CAA and all the requirements
applicable to the Area under section 110
of the CAA (general SIP requirements)
and part D of Title I of the CAA (SIP
requirements for nonattainment areas)
must be met.
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS
a. Section 110 General SIP
Requirements
Section 110(a)(2) of Title I of the CAA
delineates the general requirements for
a SIP, which include enforceable
emissions limitations and other control
measures, means, or techniques,
provisions for the establishment and
operation of appropriate devices
necessary to collect data on ambient air
quality, and programs to enforce the
limitations. The general SIP elements
and requirements set forth in section
110(a)(2) of the CAA include, but are
not limited to the following: (1)
Submittal of a SIP that has been adopted
by the state after reasonable public
notice and hearing; (2) provisions for
establishment and operation of
appropriate procedures needed to
monitor ambient air quality; (3)
implementation of a source permit
program; provisions for the
implementation of Part C requirements
(PSD); (4) provisions for the
implementation of Part D requirements
for NSR permit programs; (5) provisions
for air pollution modeling; and (6)
provisions for public and local agency
participation in planning and emission
control rule development.
Section 110(a)(2)(D) of the CAA
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
VerDate Mar<15>2010
15:41 May 02, 2014
Jkt 232001
programs to address the interstate
transport of air pollutants in accordance
with the NOX SIP Call (63 FR 57356,
October 27, 1998), amendments to the
NOX SIP Call (64 FR 26298, May 14,
1999 and 65 FR 11222, March 2, 2000),
and CAIR (70 FR 25162, May 12, 2005).
However, 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 these requirements are
applicable requirements for purposes of
redesignation.
In addition, EPA believes that the
other section 110(a)(2) elements of the
CAA not connected with nonattainment
plan submissions and not linked with
an area’s attainment status are not
applicable requirements for purposes of
redesignation. The Martinsburg Area
will still be subject to these
requirements after it is redesignated.
EPA concludes that section 110(a)(2) of
the CAA 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, and
that section 110(a)(2) elements of the
CAA not linked in the area’s
nonattainment status are not applicable
for purposes of redesignation. This
approach is consistent with EPA’s
existing policy on applicability of
conformity (i.e., for redesignations) and
oxygenated fuels requirement. See
Reading, Pennsylvania, proposed and
final rulemakings (61 FR 53174, October
10, 1996), (62 FR 24826, May 7, 1997);
Cleveland-Akron-Lorain, Ohio final
rulemaking (61 FR 20458, May 7, 1996);
and Tampa, Florida final rulemaking (60

EPA has reviewed the West Virginia
SIP and has concluded that it meets the
general SIP requirements under section
110(a)(2) of the CAA to the extent they
are applicable for purposes of
redesignation. EPA has previously
approved provisions of West Virginia’s
SIP addressing section 110(a)(2)
requirements, including provisions
addressing PM2.5. See (76 FR 47062,
August 4, 2011). These requirements
are, however, statewide requirements
that are not linked to the PM2.5
nonattainment status of the Martinsburg
Area. Therefore, EPA believes that these
SIP elements are not applicable
requirements for purposes of review of
West Virginia’s PM2.5 redesignation
request.
b. Subpart 4 Requirements
Subpart 1 sets forth the basic
nonattainment plan requirements
applicable to PM2.5 nonattainment areas.
Under section 172 of the CAA, states
with nonattainment areas must submit
plans providing for timely attainment
and meet a variety of other
requirements.
The General Preamble for
Implementation of Title I discusses the
evaluation of these requirements in the
context of EPA’s consideration of a
redesignation request. The General
Preamble sets forth EPA’s view of
applicable requirements for purposes of
evaluating redesignation requests when
an area is attaining the standard. See 57
FR 13498 (April 16, 1992).
As noted previously, EPA has
determined that the Martinsburg Area
has attained the 1997 annual PM2.5
NAAQS. Pursuant to 40 CFR 51.2004(c),
the requirement for West Virginia to
submit for the West Virginia portion of
the Martinsburg Area an attainment
demonstration and associated RACM, an
RFP plan, contingency measures, and
other planning SIPs related to the
attainment of the 1997 annual PM2.5
NAAQS are suspended until the Area is
redesignated to attainment for the
standard, or EPA determines that the
Area again violated the standard, at
which time such plans are required to
E:\FR\FM\05MYP1.SGM
05MYP1
25550
Federal Register / Vol. 79, No. 86 / Monday, May 5, 2014 / Proposed Rules
be submitted. Since the Area has
reached attainment for the 1997 annual
PM2.5 NAAQS and continues to attain
the standard, no additional measures are
needed to provide for attainment.
Therefore, the requirements of sections
172(c)(1), 172(c)(2), 172(c)(6), and
172(c)(9) of the CAA are no longer
considered to be applicable for purposes
of redesignation of the Area for the 1997
annual PM2.5 NAAQS.
Section 172(c)(3) of the CAA requires
submission and approval of a
comprehensive, accurate and current
inventory of actual emissions. As a
result of EPA’s determination of
attainment of the Area for the 1997
annual PM2.5 NAAQS, in which certain
planning requirements were suspended
for the standard, the only remaining
requirement under section 172 of the
CAA to be considered for purposes of
redesignation of the Area is the
comprehensive emissions inventory
required under section 172(c)(3) of the
CAA. As part of West Virginia’s August
5, 2013 submittal, the State submitted a
2007 base year emissions inventory for
the West Virginia portion of the
Martinsburg Area for the 1997 annual
PM2.5 NAAQS which includes
emissions estimates that cover the
general source categories of point
sources, nonroad mobile sources, area
sources and on-road mobile sources.
The pollutants that comprise the
inventory are NOX, VOCs, PM2.5, NH3,
and SO2.
In this rulemaking action, EPA is
proposing to approve West Virginia’s
2007 base year emissions inventory in
accordance with section 172(c)(3) of the
CAA. Final approval of the 2007 base
year emissions inventory will satisfy the
emissions inventory requirement under
section 172(c)(3) of the CAA. For more
information on the evaluation and
EPA’s analysis of the 2007 base year
emissions inventory, see Appendix B of
the State submittal and the emissions
inventory technical support document
(TSD) dated January 14, 2014, available
on line at www.regulations.gov, Docket
ID No. EPA–OAR–R03–2013–0690. A

emissions inventory is shown in

Section 172(c)(4) of the CAA requires
the identification and quantification of
allowable emissions for major new and
modified stationary sources in an area,
and section 172(c)(5) of the CAA
requires source permits for the
construction and operation of new and
modified major stationary sources
anywhere in the nonattainment area.
EPA has determined that, since the PSD
requirements will apply after
redesignation, areas being redesignated
need not comply with the requirement
that a nonattainment NSR program be
approved prior to redesignation,
provided that the area demonstrates
maintenance of the NAAQS without
part D NSR. 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 NSR Requirements for
Areas Requesting Redesignation to
Attainment.’’ Nevertheless, West
Virginia currently has an approved NSR
program, codified in 45 CSR 19. See 71
FR 64468 (November 2, 2006)
(approving NSR program into the SIP).
See also 77 FR 63736 (October 17, 2012)
(approving revisions to West Virginia’s
PSD program). However, West Virginia’s
PSD program for the 1997 annual PM2.5
VerDate Mar<15>2010
15:41 May 02, 2014
Jkt 232001
NAAQS will become effective in the
Martinsburg Area upon redesignation to
attainment.
Section 172(c)(7) of the CAA requires
the SIP to meet the applicable
provisions of section 110(a)(2) of the
CAA. As noted previously, EPA believes
the West Virginia SIP meets the
requirements of section 110(a)(2) of the
CAA that are applicable for purposes of
redesignation.
Section 175A of the CAA requires a
state seeking redesignation to
attainment to submit a SIP revision to
provide for the maintenance of the
NAAQS in the area ‘‘for at least 10 years
after the redesignation.’’ In conjunction
with its request to redesignate the West
Virginia portion of the Martinsburg Area
to attainment status, West Virginia
submitted SIP revisions to provide for
maintenance of the 1997 annual PM2.5
NAAQS in the Area for at least 10 years
after redesignation, throughout 2025.
West Virginia is requesting that EPA
approve this SIP revision as meeting the
requirement of section 175A of the
CAA. Once approved, the maintenance
plan for the West Virginia portion of the
Martinsburg Area will ensure that the
SIP for West Virginia meets the
requirements of the CAA regarding
maintenance of the 1997 annual PM2.5
PO 00000
Frm 00018
Fmt 4702
Sfmt 4702
NAAQS for the Area. EPA’s analysis of
the maintenance plan is provided in
section V.B. of today’s proposed
rulemaking action.
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 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 which EPA promulgated
pursuant to its authority under the CAA.
EPA interprets the conformity SIP
requirements as not applying for
purposes of evaluating the redesignation
request under section 107(d) of the CAA
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)
E:\FR\FM\05MYP1.SGM
05MYP1
25551
Federal Register / Vol. 79, No. 86 / Monday, May 5, 2014 / Proposed Rules
(upholding this interpretation). See also
60 FR 62748 (December 7, 1995)
(discussing Tampa, Florida).
Thus, for purposes of redesignating to
attainment the Martinsburg Area for the
1997 annual PM2.5 NAAQS, EPA
determines that the Area has met all
applicable SIP requirements under part
D of Title I of the CAA. EPA also
determines that upon final approval of
the 2007 comprehensive emissions
inventory as proposed in this
rulemaking action, the Martinsburg Area
will also meet all applicable SIP
requirements under part D of Title I of
the CAA for purposes of redesignating
the Area to attainment for the 1997
annual PM2.5 NAAQS.
c. The West Virginia Portion of the
Martinsburg Area Has a Fully Approved
Applicable SIP Under Section 110(k) of
the CAA
For purposes of redesignation to
attainment for the 1997 annual PM2.5
NAAQS, EPA has fully approved all
applicable requirements of the West
Virginia SIP for the Area in accordance
with section 110(k) of the CAA. Upon
final approval of the 2007
comprehensive emissions inventory
proposed in this rulemaking action, EPA
will have fully SIP-approved all
applicable requirements of the West
Virginia SIP for the Area for purposes of
redesignaton to attainment for the 1997
annual PM2.5 NAAQS in accordance
with section 110(k) of the CAA.
3. Permanent and Enforceable
Reductions in Emissions
For redesignating a nonattainment
area to attainment, section
107(d)(3)(E)(iii) of 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 and
applicable Federal air pollution control
regulations and other permanent and
enforceable reductions.
In making this demonstration, West
Virginia has calculated the change in
emissions between 2005, one of the
years used to designate the Area as
nonattainment, and 2007, one of the
years the Area monitored attainment as
provided in Table 3. Sectors included in
Table 3 are point, including airports;
area; locomotive and marine (LM);
nonroad; fire; and onroad. There are no
EGUs located in Berkeley County. The
reduction in emissions and the
corresponding improvement in air
quality from 2005 to 2007 in the
Martinsburg Area can be attributed to a
number of regulatory control measures
that have been implemented in the Area
and contributing areas in recent years.
For more information on EPA’s analysis
of the 2005 and 2007 emissions
inventory, see EPA’s emissions
inventory TSD dated January 14, 2014,

Federal Register / Vol. 79, No. 86 / Monday, May 5, 2014 / Proposed Rules
a. Federal Measures Implemented
Reductions in PM2.5 precursor
emissions have occurred statewide and
in upwind states as a result of Federal
emission control measures, with
additional emission reductions expected
to occur in the future. The Tier 2
Emission Standards for Vehicles and
Gasoline Sulfur Standards (Tier 2
Standards) have resulted in lower NOX
and SO2 emissions from new cars and
light duty trucks, including sport utility
vehicles. The Federal rules were phased
in between 2004 and 2009. EPA has
estimated that, after phasing in the new
requirements, new vehicles emit less
NOX in the following percentages:
Passenger cars (light duty vehicles)—77
percent; light duty trucks, minivans,
and sports utility vehicles—86 percent;
and larger sports utility vehicles, vans,
and heavier trucks—69–95 percent. EPA
expects fleet wide average emissions to
decline by similar percentages as new
vehicles replace older vehicles. The Tier
2 standards also reduced the sulfur
content of gasoline to 30 parts per
million (ppm) beginning in January
2006, which reflects up to a 90 percent
reduction in sulfur content.
EPA issued the Heavy-Duty Diesel
Engine Rule in July 2000. 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 reduced PM2.5
emissions from heavy-duty highway
engines and further reduced the
highway diesel fuel sulfur content to 15
ppm. The total program is estimated to
achieve a 90 percent reduction in direct
PM2.5 emissions and a 95 percent
reduction in NOX emissions for these
new engines using low sulfur diesel,
compared to existing engines using
higher sulfur diesel fuel. The reduction
in fuel sulfur content also yielded an
immediate reduction in particulate
sulfate emissions from all diesel
vehicles.
In May 2004, EPA promulgated the
Nonroad Diesel Rule for large nonroad
diesel engines, such as those used in
construction, agriculture, and mining, to
be phased in between 2008 and 2014.
The rule also reduces the sulfur content
in nonroad diesel fuel by over 99
percent. Prior to 2006, nonroad diesel
fuel averaged approximately 3,400 ppm
sulfur. This rule limited nonroad diesel
sulfur content to 500 ppm by 2006, with
a further reduction to 15 ppm by 2010.
As required by the CAA, EPA
developed Maximum Available Control
Technology (MACT) Standards to
regulate emissions of toxic air pollutants
from a published list of industrial
sources referred to as ‘‘source
VerDate Mar<15>2010
15:41 May 02, 2014
Jkt 232001
categories.’’ The list of MACT source
categories that must meet control
technology requirements to reduce the
emission of toxic air pollutants with
compliance dates on or after 2005, is
found in the West Virginia’s August 5,
2013 submittal on page 48, available on
line at www.regulations.gov, Docket ID
No. EPA–OAR–R03–2013–0690.
b. State and Local Measures
EPA issued the NOX SIP Call in 1998
pursuant to the CAA to require 22 states
and the District of Columbia to reduce
NOX emissions from large EGUs and
large non-EGUs such as industrial
boilers, internal combustion engines,
and cement kilns. See (63 FR 57356,
October 27, 1998). EPA approved West
Virginia’s Phase I NOX SIP Call rule on
May 10, 2002 (67 FR 31733) and Phase
II rule on September 28, 2006 (71 FR
56881). Emission reductions resulting
from regulations developed in response
to the NOX SIP Call are permanent and
enforceable.
On March 10, 2005, EPA issued CAIR,
which applies to 27 states and the
District of Columbia. CAIR relied on 3
separate cap-and-trade programs to
reduce SO2 and NOX emissions. On
August 4, 2009 (74 FR 38536), EPA
approved West Virginia’s CAIR rules
into the West Virginia SIP. The
maintenance plan for the Area for the
1997 annual PM2.5 NAAQS, thus, list
CAIR as a control measure for the
purpose of reducing SO2 and NOX
emissions. On August 8, 2011 (76 FR
48208), EPA promulgated CSAPR to
replace CAIR, which has been in place
since 2005. The D.C. Circuit Court
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
21, 2012, the D.C. Circuit Court issued
a decision to vacate CSAPR. In that
decision, it also ordered EPA to
continue administering CAIR ‘‘pending
the promulgation of a valid
replacement.’’ EME Homer City, 696
F.3d at 38. EPA and other parties have
filed petitions for certiorari to the U.S.
Supreme Court, and on June 24, 2013,
the Supreme Court granted certiorari on
EPA’s petition for appeal of EME Homer
City Generation. See EME Homer City
Generation, L.P. v. EPA, 696 F .3d 7
(D.C. Cir. 2012), cert. granted, 570
U.S.—(2013). Nonetheless, EPA intends
to continue to act in accordance with
the EME Homer City opinion.
As noted earlier, EPA believes it is
appropriate to allow states to rely on the
existing emissions reductions achieved
PO 00000
Frm 00020
Fmt 4702
Sfmt 4702
by CAIR, as sufficiently permanent and
enforceable pending a valid replacement
rule, for purposes such as a
redesignation. CAIR was in place and
thus getting emission reductions when
the Martinsburg Area monitored
attainment of the 1997 annual PM2.5
NAAQS. The monitoring data used to
demonstrate the Area’s attainment of the
1997 annual PM2.5 NAAQS was
impacted by CAIR. EPA finds West
Virginia appropriately included CAIR as
a control measure in this SIP revision.
Furthermore, the air quality modeling
analysis conducted for the Transport
Rule demonstrates that the Area would
be able to attain the 1997 annual PM2.5
NAAQS even in the absence of either
CAIR or the Transport Rule. EPA’s
modeling projections show that all
ambient monitors in the Area are
expected to continue to maintain
compliance in the 2012 and 2014 ‘‘no
CAIR’’ base cases. Therefore, none of the
ambient monitoring sites in the Area are
‘‘receptors’’ that EPA projects will have
future nonattainment problems or
difficulty maintaining the NAAQS.
Based on the information summarized
above, West Virginia has adequately
demonstrated that the improvement in
air quality is due to permanent and
enforceable emissions reductions. The
reductions result from Federal
requirements, regulation of precursors
under the NOX SIP Call, and CAIR,
which are expected to continue into the
future.
B. Maintenance Plan
On August 5, 2013, WVDEP submitted
a maintenance plan for the West
Virginia portion of the Martinsburg Area
for the 1997 annual PM2.5 NAAQS as
required by section 175A of the CAA.
EPA’s analysis for proposing approval of
the maintenance plan is provided in this
section.
1. Attainment Emissions Inventory
An attainment inventory is comprised
of the emissions during the time period
associated with the monitoring data
showing attainment. WVDEP developed
emissions inventories for NOX, PM2.5,
SO2, VOC, and NH3 for 2007, one of the
years in the period during which the
Martinsburg Area monitored attainment
of the 1997 annual PM2.5 standard, as
described previously.
WVDEP used the 2007 annual
emissions inventory submitted to EPA’s
National Emissions Inventory (NEI)
database to compile their inventory.
There are no EGU’s in Berkeley County.
For the 2007 area source emissions,
WDEP used the Southern Modeling,
Analysis, and Planning (SEMAP)
project.
E:\FR\FM\05MYP1.SGM
05MYP1
25553
Federal Register / Vol. 79, No. 86 / Monday, May 5, 2014 / Proposed Rules
For the 2007 nonroad mobile sources,
WVDEP generated the emissions using
EPA’s NONROAD model. The 2007
onroad mobile source inventory was
developed using the most current
version of EPA’s highway mobile source
emissions model MOVES2010a.
EPA has reviewed the documentation
provided by WVDEP and found the
emissions inventory to be acceptable.
For more information on EPA’s analysis
of the 2007 emissions inventory, see
Appendix B of the State submittal and
the emissions inventory TSD dated
January 14, 2014, available on line at
www.regulations.gov, Docket ID No.
EPA–OAR–R03–2013–0690.
2. Maintenance Demonstration
Section 175A requires a state seeking
redesignation to attainment to submit a
SIP revision to provide for the
maintenance of the NAAQS in the area
‘‘for at least 10 years after the
redesignation.’’ EPA has interpreted this
as a showing of maintenance ‘‘for a
period of ten years following
redesignation.’’ Where the emissions
inventory method of showing
maintenance is used, its purpose is to
show that emissions during the
maintenance period will not increase
over the attainment year inventory. See
1992 Calcagni Memorandum, pages 9–
10.
For a demonstration of maintenance,
emissions inventories are required to be
projected to future dates to assess the
influence of future growth and controls;
however, the maintenance
demonstration need not be based on
modeling. See Wall v. EPA, supra;
Sierra Club v. EPA, supra. See also 66
FR 53099–53100; 68 FR 25430–32.
WVDEP uses projection inventories to
show that the Area will remain in
attainment and developed projection
inventories for an interim year of 2017
and a maintenance plan end year of
2025 to show that future emissions of
NOX, SO2, VOC, NH3, and PM2.5 will
remain at or below the attainment year
2007 emissions levels throughout the
Martinsburg Area through the year 2025.
The projection inventories for the
2017 and 2025 point, area, and nonroad
sources were developed by the SEMAP
contractors. Detailed discussion of how
projections were developed are
contained in the document ‘‘SESARM
Projection Year Final Report_Rev Jan 20
2013.pdf.’’ Onroad mobile source
projection inventories for Berkeley
County were prepared by Michael Baker
Jr., Inc. and onroad mobile source
emissions for 2017 and 2025 were
calculated from emission factors from
MOVES2010 model runs. See Appendix
C of the State submittal. EPA has
reviewed the documentation provided
by WVDEP and found the
methodologies acceptable.
EPA has determined that the
emissions inventories that the 2017 and
2025 projected emissions inventories
provided by WVDEP are approvable. For
more information on EPA’s analysis of
the emissions inventory, see Appendix
B of the State submittal and EPA’s TSD
dated January 14, 2014, available on line
at www.regulations.gov., Docket ID No.
EPA–OAR–R03–2013–0690. Table 4
provides the inventories for the 2007
attainment year, the 2017 interim year,
and the 2025 maintenance plan end year
for the Area.

Table 4 shows that between 2007 and
2017, the Area is projected to reduce
SO2 emissions by 1,387 tpy, NOX
emissions by 7,168 tpy, PM2.5 emissions
by 267 tpy, NH3 by 37 tpy, and VOC by
2,441 tpy. Between 2007 and 2025, the
Area is projected to reduce SO2
emissions by 1,273 tpy, NOX emissions
by 9,224 tpy, PM2.5 emissions by 301
tpy, NH3 by 23 tpy, and VOC by 2,802
tpy. Thus, the projected emissions
inventories show that the Area will
continue to maintain the 1997 annual
PM2.5 NAAQS during the 10 year
maintenance period.

3. Monitoring Network
EPA has determined that West
Virginia’s maintenance plan includes a
commitment to continue to operate its
EPA-approved monitoring network, as
necessary to demonstrate ongoing
compliance with the NAAQS. There are
two PM2.5 monitors in the Martinsburg
Area. One is located in West Virginia
operated by the West Virginia Division
of Air Quality, and the other one is

located in Maryland operated by the
Maryland Department of the
Environment. In its August 5, 2013
submittal, West Virginia stated that it
will consult with EPA prior to making
any necessary changes to the network
and will continue to quality assure the
monitoring data in accordance with the
requirements of 40 CFR part 58.
4. Verification of Continued Attainment
To provide for tracking of the
emission levels in the Area, WVDEP
requires major point sources to submit
air emissions information annually and
prepares a new periodic inventory for
all PM2.5 precursors every three years in
accordance with EPA’s Air Emissions
Reporting Requirements (AERR). EPA
has determined that WVDEP will
continue to compare emissions
information to the attainment year
inventory to assure continued
attainment with the 1997 annual PM2.5
NAAQS and that WVDEP will use this
information to assess emissions trends,
as necessary.

5. Contingency Measures
The contingency plan provisions for
maintenance plans are designed to
promptly correct a violation of the
NAAQS that occurs after redesignation.
Section 175A of the CAA requires that
a maintenance plan include such
contingency measures as EPA deems
necessary to ensure that a state will
promptly correct a violation of the
NAAQS that occurs after redesignation.
The maintenance plan should identify
the events that would ‘‘trigger’’ the
adoption and implementation of a
contingency measure(s), the
contingency measure(s) that would be
adopted and implemented, and the
schedule indicating the time frame by
which the state would adopt and
implement the measure(s).
West Virginia’s maintenance plan
outlines the procedures for the adoption
and implementation of contingency
measures to further reduce emissions
should a violation occur. West
Virginia’s contingency measures include
a warning level response and an action
E:\FR\FM\05MYP1.SGM
05MYP1
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS
25554
Federal Register / Vol. 79, No. 86 / Monday, May 5, 2014 / Proposed Rules
level response. An initial warning level
response is triggered when the average
weighted annual mean for a single
calendar year exceeds 15.5 mg/m3 within
the maintenance area. In that case, a
study will be conducted to determine if
the emissions trends show increases; if
action is necessary to reverse emissions
increases, West Virginia will follow the
same procedures for control selection
and implementation as for an action
level response, and implementation of
necessary controls will take place as
expeditiously as possible, but no later
than 12 months from the end of the
most recent calendar year.
The action level response will be
prompted by any one of the following:
(1) A warning level response study that
shows emissions increases; (2) a
weighted annual mean over a two-year
average that exceeds the standard; or (3)
a violation of the standard in the
maintenance area. If an action level
response is triggered, West Virginia will
adopt and implement appropriate
control measures within 18 months
from the end of the year in which
monitored air quality triggering a
response occurs. West Virginia will also
consider whether additional regulations
that are not a part of the maintenance
plan can be implemented in a timely
manner to respond to the trigger.
West Virginia’s candidate contingency
measures include the following: (1)
Diesel reduction emission strategies; (2)
alternative fuels and diesel retrofit
programs for fleet vehicle operations; (3)
PM2.5, SO2, and NOX emissions offsets
for new and modified major sources; (4)
concrete manufacturing controls; and (5)
additional NOX reductions.
Additionally, West Virginia has
identified a list of sources that could
potentially be controlled. These include:
Industrial, commercial and institutional
(ICI) Boilers for SO2 and NOX controls,
EGUs, process heaters, internal
combustion engines, combustion
turbines, other sources greater than 100
tpy, fleet vehicles, concrete
manufacturers, and aggregate processing
plants. EPA finds that the West Virginia
maintenance plan for the Martinsburg
Area includes appropriate contingency
measures as necessary to ensure West
Virginia will promptly correct any
violation of the NAAQS that occurs after
redesignation. For all of the reasons
discussed above, EPA is proposing to
approve West Virginia’s 1997 annual
PM2.5 maintenance plan for the
Martinsburg Area as meeting the
requirements of section 175A of the
CAA.
VerDate Mar<15>2010
15:41 May 02, 2014
Jkt 232001
C. Transportation Conformity
Section 176(c) of the CAA requires
Federal actions in nonattainment and
maintenance areas to ‘‘conform to’’ the
goals of SIPs. This means that such
actions will not cause or contribute to
violations of a NAAQS, worsen the
severity of an existing violation, or
delay timely attainment of any NAAQS
or any interim milestone. Actions
involving Federal Highway
Administration (FHWA) or Federal
Transit Administration (FTA) funding
or approval are subject to the
transportation conformity rule (40 CFR
Part 93, subpart A). Under this rule,
metropolitan planning organizations
(MPOs) in nonattainment and
maintenance areas coordinate with state
air quality and transportation agencies,
EPA, and the FHWA and FTA to
demonstrate that their long range
transportation plans and transportation
improvement programs (TIP) conform to
applicable SIPs. This is typically
determined by showing that estimated
emissions from existing and planned
highway and transit systems are less
than or equal to the MVEBs contained
in the SIP.
On August 5, 2013, West Virginia
submitted a SIP revision that contains
the 2017 and 2025 PM2.5 and NOX
onroad mobile source budgets for the
Martinsburg Area that comprises
Berkeley County, West Virginia. West
Virginia did not provide emission
budgets for SO2, VOC, and NH3 because
it concluded, consistent with the
presumptions regarding these
precursors in the Transportation
Conformity Rule at 40 CFR
93.102(b)(2)(v), which predated and was
not disturbed by the litigation on the
1997 PM2.5 Implementation Rule, that
emissions of these precursors from
motor vehicles are not significant
contributors to the Area’s PM2.5 air
quality problem. EPA issued conformity
regulations to implement the 1997
annual PM2.5 NAAQS in July 2004 and
May 2005 (69 FR 40004, July 1, 2004
and 70 FR 24280, May 6, 2005). Those
actions were not part of the final rule
recently remanded to EPA by the D.C.
Circuit Court in NRDC v. EPA, No. 08–
1250 (January 4, 2013), in which the
D.C. Circuit Court remanded to EPA the
1997 PM2.5 Implementation Rule
because it concluded that EPA must
implement that NAAQS pursuant to the
PM-specific implementation provisions
of subpart 4, rather than solely under
the general provisions of subpart 1. That
decision does not affect EPA’s proposed
approval of the MVEBs for the
Martinsburg Area. The MVEBs are
presented in Table 5.

EPA’s substantive criteria for
determining adequacy of MVEBs are set
out in 40 CFR 93.118(e)(4).
Additionally, to approve the MVEBs,
EPA must complete a thorough review
of the SIP, in this case the PM2.5
maintenance plan, and conclude that
with the projected level of motor vehicle
and all other emissions, the SIP will
achieve its overall purpose, in this case
providing for maintenance of the 1997
annual PM2.5 NAAQS. EPA’s process for
determining adequacy of a MVEB
consists of three basic steps: (1)
Providing public notification of a SIP
submission; (2) providing the public the
opportunity to comment on the MVEB
during a public comment period; and (3)
EPA taking action on the MVEB.
On December 20, 2013, EPA initiated
an adequacy review of the MVEBs for
the 1997 annual PM2.5 NAAQS that
West Virginia included in its
redesignation request submittal. As
such, a notice of the submission of these
MVEBs were posted on the adequacy
Web site (https://www.epa.gov/otaq/
stateresources/transconf/currsips.htm).
The public comment period closed on
January 21, 2014. There were no public
comments received. EPA is acting on
making the adequacy finding final
through a separate notice of adequacy.
EPA has reviewed the MVEBs and
found them consistent with the
maintenance plan and that the budgets
meet the criteria for adequacy and
approval.
Therefore, EPA is proposing to
approve the 2017 and 2025 PM2.5 and
NOX MVEBs for Berkeley County for
transportation conformity purposes.
Additional information pertaining to the
review of the MVEBs can be found in
the TSD dated January 28, 2014,

VI. Proposed Actions
EPA is proposing to approve the
redesignation of the West Virginia
portion of the Martinsburg Area from
nonattainment to attainment for the
1997 annual PM2.5 NAAQS. EPA has
evaluated West Virginia’s redesignation
request and determined that it meets the
redesignation criteria set forth in section
107(d)(3)(E) of the CAA. EPA believes
that the monitoring data demonstrate
E:\FR\FM\05MYP1.SGM
05MYP1
Federal Register / Vol. 79, No. 86 / Monday, May 5, 2014 / Proposed Rules
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS
that the Martinsburg Area has attained
the 1997 annual PM2.5 NAAQS and will
continue to attain the standard. Final
approval of this redesignation request
would change the designation of the
West Virginia portion of the
Martinsburg Area from nonattainment to
attainment for the 1997 PM2.5 annual
NAAQS. EPA is also proposing to
approve the associated maintenance
plan for the Area submitted on August
5, 2013, as a revision to the West
Virginia SIP because it meets the
requirements of section 175A of the
CAA as described previously in this
rulemaking notice. In addition, EPA is
proposing to approve the 2007 base year
emissions inventory as meeting the
requirement of section 172(a)(3) of the
CAA. Furthermore, EPA is proposing to
approve the 2017 and 2025 PM2.5 and
NOX MVEBs submitted by West Virginia
for Berkeley County for transportation
purposes. EPA is soliciting public
comments on the issues discussed in
this document. These comments will be
considered before taking final action.
VII. 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 proposes to approve 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 Order 12866 (58 FR 51735,
October 4, 1993);
• 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
VerDate Mar<15>2010
15:41 May 02, 2014
Jkt 232001
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 rule proposing to
approve West Virginia’s redesignation
request, maintenance plan, 2007 base
year emissions inventory, and MVEBs
for transportation conformity purposes
for the West Virginia portion of the
Martinsburg Area for the 1997 annual
PM2.5 NAAQS, 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.

AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve the State of West Virginia's request to redesignate to
attainment the West Virginia portion of the Martinsburg-Hagerstown, WV-
MD nonattainment area (Martinsburg Area or Area) for the 1997 annual
fine particulate matter (PM2.5) national ambient air quality
standard (NAAQS). EPA is also proposing to determine that the
Martinsburg Area continues to attain the 1997 annual PM2.5
NAAQS. In addition, EPA is proposing to approve as a revision to the
West Virginia State Implementation Plan (SIP), the associated
maintenance plan to show maintenance of the 1997 annual
PM2.5 NAAQS through 2025 for the Area. The maintenance plan
includes the 2017 and 2025 PM2.5 and nitrogen oxides
(NOX) mobile vehicle emissions budgets (MVEBs) for Berkeley
County, West Virginia for the 1997 annual PM2.5 NAAQS which
EPA is proposing to approve for transportation conformity purposes.
Furthermore, EPA is proposing to approve as a revision to the West
Virginia SIP, the 2007 base year emissions inventory for the Area for
the 1997 annual PM2.5 NAAQS. These actions are being taken
under the Clean Air Act (CAA).

I. Background
The first air quality standards for PM2.5 were
established on July 18, 1997 (62 FR 38652). EPA promulgated an annual
standard at a level of 15 micrograms per cubic meter ([mu]g/m\3\),
based on a three-year average of annual mean PM2.5
concentrations (the 1997 annual PM2.5 standard). In the same
rulemaking, EPA promulgated a 24-hour standard of 65 [mu]g/m\3\ based
on a three-year average of the 98th percentile of 24-hour
concentrations.
On January 5, 2005 (70 FR 944, 1014), EPA published air quality
area designations for the 1997 PM2.5 NAAQS. In that
rulemaking action, EPA designated the Martinsburg Area as nonattainment
for the 1997 annual PM2.5 NAAQS. The Martinsburg Area is
comprised of Berkeley County in West Virginia (the West Virginia
portion of the Area) and Washington County in Maryland. See 40 CFR
81.321 (Maryland) and 40 CFR 81.349 (West Virginia).
On October 17, 2006 (71 FR 61144), EPA retained the annual average
standard at 15 [mu]g/m\3\ but revised the 24-hour standard to 35 [mu]g/
m\3\, based again on the three-year average of the 98th percentile of
the 24-hour concentrations (the 2006 annual PM2.5 standard).
On November 13, 2009 (74 FR 58688), EPA published designations for the
2006 24-hour PM2.5 standard, which became effective on
December 14, 2009. In that rulemaking action, EPA designated the
Martinsburg Area as attainment for the 2006 24-hour PM2.5
NAAQS. See 74 FR 58737 and 40 CFR 81.321 (Maryland) and also see 74 FR
58775 and 40 CFR 81.349 (West Virginia).
In response to legal challenges of the annual standard promulgated
in 2006, the D.C. Circuit Court remanded the 2006 annual standard to
EPA for further consideration. See American Farm Bureau Federation and
National Pork Producers Council, et. al. v. EPA, 559 F.3d 512 (D.C.
Cir. 2009). However, given that the 1997 annual and the 2006 annual
PM2.5 standards are essentially identical, attainment of the
1997 annual PM2.5 standard would also indicate attainment of
the remanded 2006 annual PM2.5 standard. Since the
Martinsburg Area is designated nonattainment for the annual NAAQS
promulgated in 1997, today's proposed rulemaking action addresses the
redesignation to attainment only for this standard.
On November 20, 2009 (74 FR 60199), EPA determined that the
Martinsburg Area had attained the 1997 annual PM2.5 NAAQS.
Pursuant to 40 CFR 51.1004(c) and based on this determination, the
requirements for the Martinsburg Area to submit an attainment
demonstration and associated reasonably available control measures
(RACM), a reasonable further progress (RFP) plan, contingency measures,
and other planning SIP revisions related to the attainment of the 1997
annual PM2.5 NAAQS were suspended until such time as: (1)
The Area is redesignated to attainment for the standard, at which time
the requirements no longer apply; or (2) EPA determines that the Area
has again violated the standard, at which time such plans are required
to be submitted. On January 20, 2012 (77 FR 1411), EPA also determined
that the Martinsburg Area had attained the 1997 annual PM2.5
NAAQS by the applicable date of April 5, 2010.
On August 5, 2013, the State of West Virginia through the West
Virginia Department of Environmental Protection (WVDEP) formally
submitted a request to redesignate the West Virginia portion of the
Martinsburg Area from nonattainment to attainment for the 1997 annual
PM2.5 NAAQS. Concurrently, WVDEP submitted a maintenance
plan for the Area as a SIP revision to ensure continued attainment
throughout the Area over the next 10
[[Page 25542]]
years. The maintenance plan also includes a 2007 base year emissions
inventory for PM2.5, NOX, sulfur dioxide
(SO2), volatile organic compounds (VOC) and ammonia
(NH3) for the1997 annual PM2.5 NAAQS in order to
meet the emissions inventory requirement of section 172(c)(3) of the
CAA. In addition, the maintenance plan includes the 2017 and 2025
PM2.5 and NOX MVEBs used for transportation
conformity purposes for Berkeley County, West Virginia for the 1997
annual PM2.5 NAAQS.
In this proposed rulemaking action, EPA takes into account two
decisions of the United States Court of Appeals for the District of
Columbia (D.C. Circuit Court). In the first of the two D.C. Circuit
Court decisions, the D.C. Circuit Court, on August 21, 2012, issued EME
Homer City Generation, L.P. v. EPA, 696 F.3d 7 (D.C. Cir. 2012), which
vacated and remanded the Cross-State Air Pollution Control Rule (CSAPR)
and ordered EPA to continue administering the Clean Air Interstate Rule
(CAIR) ``pending . . . development of a valid replacement.'' EME Homer
City at 38. The D.C. Circuit Court denied all petitions for rehearing
on January 24, 2013. EPA and other parties filed for certiorari to the
Supreme Court, and on June 24, 2013, the Supreme Court granted
certiorari on EPA's petition for appeal of EME Homer City Generation.
See EME Homer City Generation, L.P. v. EPA, 696 F.3d 7 (D.C. Cir.
2012), cert. granted, 570 U.S.--(2013). Nonetheless, EPA intends to
continue to act in accordance with the EME Homer City opinion. In the
second decision, on January 4, 2013, in Natural Resources Defense
Council (NRDC) v. EPA, the D.C. Circuit Court remanded to EPA the
``Final Clean Air Fine Particle Implementation Rule'' (72 FR 20586,
April 25, 2007) and the ``Implementation of the New Source Review (NSR)
Program for Particulate Matter Less than 2.5 Micrometers
(PM2.5)'' final rule (73 FR 28321, May 16, 2008). 706 F.3d
428 (D.C. Cir. 2013).
II. EPA's Requirements
A. Criteria for Redesignation to Attainment
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) EPA determines that the
area has attained the applicable NAAQS; (2) EPA has fully approved the
applicable implementation plan for the area under section 110(k) of the
CAA; (3) EPA 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) EPA has fully approved a maintenance plan for the area as
meeting the requirements of section 175A of the CAA; and (5) the state
containing such area has met all requirements applicable to the area
under section 110 and part D of the CAA. Each of these requirements are
discussed in section V. of today's proposed rulemaking action.
EPA has provided guidance on redesignation in the ``SIPs; General
Preamble for the Implementation of Title I of the CAA Amendments of
1990,'' (57 FR 13498, April 16, 1992) (the ``General Preamble'') and
has provided further guidance on processing redesignation requests in
the following documents: (1) ``Procedures for Processing Requests to
Redesignate Areas to Attainment,'' Memorandum from John Calcagni,
Director, Air Quality Management Division, September 4, 1992 (hereafter
referred to as the ``1992 Calcagni Memorandum''); (2) ``SIP Actions
Submitted in Response to CAA Deadlines,'' Memorandum from John
Calcagni, Director, Air Quality Management Division, October 28, 1992;
and (3) ``Part D New Source Review (Part D NSR) Requirements for Areas
Requesting Redesignation to Attainment,'' Memorandum from Mary D.
Nichols, Assistant Administrator for Air and Radiation, October 14,
1994.
B. Requirements of 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 of the CAA, the plan must demonstrate continued
attainment of the applicable NAAQS for at least 10 years after approval
of a redesignation of an area 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 such
contingency measures, with a schedule for implementation, as EPA deems
necessary to assure prompt correction of any future PM2.5
violations.
The 1992 Calcagni Memorandum provides additional guidance on the
content of a maintenance plan. The memorandum states that a maintenance
plan should address the following provisions: (1) An attainment
emissions inventory; (2) a maintenance demonstration showing
maintenance for 10 years; (3) a commitment to maintain the existing
monitoring network; (4) verification of continued attainment; and (5) a
contingency plan to prevent or correct future violations of the NAAQS.
Under the CAA, states are required to submit, at various times,
control strategy SIP revisions and maintenance plans for nonattainment
areas and for areas seeking redesignation to attainment for a given
NAAQS. These emission control strategy SIP revisions (e.g., RFP and
attainment demonstration SIP revisions) and maintenance plans create
MVEBs based on onroad mobile source emissions for the relevant criteria
pollutants and/or their precursors, where appropriate, to address
pollution from onroad transportation sources. The MVEBs are the
portions of the total allowable emissions that are allocated to onroad
vehicle use that, together with emissions from all other sources in the
area, will provide attainment, RFP, or maintenance, as applicable. The
budget serves as a ceiling on emissions from an area's planned
transportation system. Under 40 CFR part 93, a MVEB for an area seeking
a redesignation to attainment is established for the last year of the
maintenance plan.
The maintenance plan for the West Virginia portion of the
Martinsburg Area, that comprises Berkeley County in West Virginia,
includes the 2017 and 2025 PM2.5 and NOX MVEBs
for transportation conformity purposes. The transportation conformity
determination for the Area is further discussed in section V.C. of
today's proposed rulemaking action and a technical support document
(TSD) dated January 28, 2014, available on line at www.regulations.gov,
Docket ID No. EPA-OAR-R03-2013-0690.
III. Summary of Proposed Actions
EPA is proposing to take several rulemaking actions related to the
redesignation of the West Virginia portion of the Martinsburg Area to
attainment for the 1997 annual PM2.5 NAAQS. EPA is proposing
to find that the Area meets the requirements for redesignation for the
1997 annual PM2.5 NAAQS under section 107(d)(3)(E) of the
CAA. EPA is thus proposing to approve West Virginia's request to change
the legal definition for the West Virginia portion of the Martinsburg
Area from nonattainment to attainment for the 1997 annual
PM2.5 NAAQS. This action does not impact the legal
definition of the Maryland portion of
[[Page 25543]]
the Area. EPA is taking separate action to redesignate the Maryland
portion.
EPA is also proposing to approve the associated maintenance plan
for the West Virginia portion of the Martinsburg Area as a revision to
the West Virginia SIP for the 1997 annual PM2.5 NAAQS,
including the 2017 and 2025 PM2.5 and NOX MVEBs
of the Area. The approval of the maintenance plan is one of the CAA
criteria for redesignation of the Area to attainment for the 1997
annual PM2.5 NAAQS. West Virginia's maintenance plan is
designed to ensure continued attainment in the West Virginia portion of
the Martinsburg Area for 10 years after redesignation for the 1997
annual PM2.5 NAAQS.
EPA previously determined that the Martinsburg Area has attained
the 1997 annual PM2.5 NAAQS. Therefore, EPA is proposing to
find that the Area continues to attain the standard. See 74 FR 60199,
November 20, 2009 and 77 FR 1411, January 10, 2012. EPA is also
proposing to approve the 2007 comprehensive emissions inventory that
includes PM2.5, SO2, NOX, VOC, and
NH3 for the West Virginia portion of the Area as a revision
to the West Virginia SIP for the 1997 annual PM2.5 NAAQS in
order to meet the requirements of section 172(c)(3) of the CAA. EPA's
analysis of the proposed actions is provided in section V. of today's
proposed rulemaking action.
IV. Effects of Recent Court Decisions on Proposed Actions
A. Effect of the August 21, 2012 D.C. Circuit Court Decision Regarding
EPA's CSAPR
1. Background
EPA promulgated CSAPR (76 FR 48208, August 8, 2011), to replace
CAIR, which has been in place since 2005. See 76 FR 59517. CAIR
requires significant reductions in emissions of SO2 and
NOX from electric generating units (EGUs) to limit the
interstate transport of these pollutants and the ozone and fine
particulate matter they form in the atmosphere. See 76 FR 70093. The
D.C. Circuit Court 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 December 30, 2011, the D.C. Circuit Court issued an order
addressing the status of CSAPR and CAIR in response to motions filed by
numerous parties seeking a stay of CSAPR pending judicial review. In
that order, the D.C. Circuit Court stayed CSAPR pending resolution of
the petitions for review of that rule in EME Homer City Generation,
L.P. v. EPA (No. 11-1302 and consolidated cases). The D.C. Circuit
Court also indicated that EPA was expected to continue to administer
CAIR in the interim until judicial review of CSAPR was completed.
On August 21, 2012, the D.C. Circuit Court issued a decision to
vacate CSAPR. In that decision, it also ordered EPA to continue
administering CAIR ``pending the promulgation of a valid replacement.''
EME Homer City, 696 F.3d at 38 (D.C. Circ. 2012). The D.C. Circuit
Court denied all petitions for rehearing on January 24, 2013. EPA and
other parties have filed petitions for certiorari to the U.S. Supreme
Court. On June 24, 2013 the Supreme Court granted EPA's petition for
certiorari. Nonetheless, EPA intends to continue to act in accordance
with the EME Homer City opinion.
2. Proposal on This Issue
In light of these unique circumstances and for the reasons
explained subsequently, to the extent that attainment is due to
emission reductions associated with CAIR, EPA is here proposing to
determine that those reductions are sufficiently permanent and
enforceable for purposes of sections 107(d)(3)(E)(iii) and 175A of the
CAA. EPA, therefore, proposes to approve the redesignation request and
the related SIP revisions for the West Virginia portion of the
Martinsburg Area (Berkeley County, West Virginia), including West
Virginia's plan for maintaining attainment of the 1997 annual
PM2.5 NAAQS in the Area.
As directed by the D.C. Circuit Court, CAIR remains in place and
enforceable until substituted by a valid replacement rule. West
Virginia's SIP revision lists CAIR as a control measure that was
approved by EPA on August 6, 2009 (74 FR 38536) and became state-
effective on May 1, 2008 for the purpose of reducing SO2 and
NOX emissions. CAIR was thus in place and getting emission
reductions when the Martinsburg Area monitored attainment of the 1997
annual PM2.5 NAAQS. The quality-assured, quality-controlled,
certified monitoring data used to demonstrate the Area's attainment of
the 1997 annual PM2.5 NAAQS was also impacted by CAIR.
To the extent that West Virginia is relying on CAIR in its
maintenance plan, the recent directive from the D.C. Circuit Court in
EME Homer City ensures that the reductions associated with CAIR will be
permanent and enforceable for the necessary time period. EPA has been
ordered by the D.C. Circuit Court to develop a new rule to address
interstate transport to replace CSAPR, and the opinion makes clear that
after promulgating that new rule, EPA must provide states an
opportunity to draft and submit SIPs to implement that rule. Thus, CAIR
will remain in place until: (1) EPA has promulgated a final rule
through a notice-and-comment rulemaking process; (2) states have had an
opportunity to draft and submit SIPs; (3) EPA has reviewed the SIPs to
determine if they can be approved; and (4) EPA has taken action on the
SIPs, including promulgating a Federal Implementation Plan (FIP) if
appropriate. The D.C. Circuit Court's clear instruction to EPA that it
must continue to administer CAIR until a valid replacement exists
provides an additional backstop. By definition, any rule that replaces
CAIR and meets the D.C. Circuit Court's direction would require upwind
states to have SIPs that eliminate significant contributions to
downwind nonattainment and prevent interference with maintenance in
downwind areas.
Further, in vacating CSAPR and requiring EPA to continue
administering CAIR, the D.C. Circuit Court emphasized that the
consequences of vacating CAIR ``might be more severe now in light of
the reliance interests accumulated over the intervening four years.''
EME Homer City, 696 F.3d at 38. The accumulated reliance interests
include the interests of states who reasonably assumed they could rely
on reductions associated with CAIR which brought certain nonattainment
areas into attainment with the NAAQS. If EPA were prevented from
relying on reductions associated with CAIR in redesignation actions,
states would be forced to impose additional, redundant reductions on
top of those achieved by CAIR. EPA believes this is precisely the type
of irrational result the D.C. Circuit Court sought to avoid by ordering
EPA to continue administering CAIR. For these reasons also, EPA
believes it is appropriate to allow states to rely on CAIR, and the
existing emissions reductions achieved by CAIR, as sufficiently
permanent and enforceable for purposes such as redesignation. Following
promulgation of the replacement rule, EPA will review SIP revisions as
appropriate to identify whether there are any issues that need to be
addressed.
[[Page 25544]]
B. Effect of the January 4, 2013 D.C. Circuit Court Decision Regarding
PM2.5 Implementation Under Subpart 4 of Part D of Title I of
the CAA
1. Background
On January 4, 2013, in NRDC v. EPA, the D.C. Circuit Court remanded
to EPA the ``Final Clean Air Fine Particle Implementation Rule'' (72 FR
20586, April 25, 2007) and the ``Implementation of the NSR Program for
PM2.5'' final rule (73 FR 28321, May 16, 2008)
(collectively, ``1997 PM2.5 Implementation Rule''). 706 F.3d
428 (D.C. Cir. 2013). The D.C. Circuit Court found that EPA erred in
implementing the 1997 annual PM2.5 NAAQS pursuant to the
general implementation provisions of subpart 1 of Part D of Title I of
the CAA (subpart 1), rather than the particulate-matter-specific
provisions of subpart 4 of Part D of Title I (subpart 4).
Prior to the January 4, 2013 decision, the states had worked
towards meeting the air quality goals of the 1997 PM2.5
NAAQS in accordance with EPA regulations and guidance derived from
subpart 1 of Part D of Title I of the CAA. Subsequent to this decision,
EPA took this history into account and responded to the D.C. Circuit
Court's remand by proposing to set a new deadline for any remaining
submissions that may be required for a moderate nonattainment area that
are due to the applicability of subpart 4 of Part D of Title I of the
CAA.
On November 21, 2013 (78 FR 69806), EPA issued a proposed rule,
Identification of Nonattainment Classification and Deadlines for
Submission of SIP Provisions for the 1997 PM2.5 NAAQS (the
PM2.5 Subpart 4 Classification and Deadline Rule)
identifying the classification under subpart 4 for areas currently
designated nonattainment for the 1997 PM2.5 standards, the
deadlines for states to submit NSR and attainment-related SIP elements
required for these areas pursuant to subpart 4, and the EPA guidance
that is currently available regarding subpart 4 requirements. If
finalized, this rule will set a deadline for states to submit
attainment plans and meet other subpart 4 requirements. The proposed
rule identified December 31, 2014 as the deadline for the states to
submit any additional attainment-related SIP elements that may be
needed to meet the applicable requirements of subpart 4 for areas
currently designated nonattainment for the 1997 PM2.5 NAAQS
and to submit SIPs addressing the nonattainment NSR requirements in
subpart 4. Since West Virginia submitted a request to redesignate the
West Virginia portion of the Martinsburg Area from nonattainment to
attainment on August 5, 2013 and the proposed PM2.5 Subpart
4 Classification and Deadline Rule identifies a December 31, 2014
deadline, West Virginia is not required at this time to meet the
applicable requirements of subpart 4.
2. Proposal on This Issue
EPA is proposing to determine that the D.C. Circuit Court's January
4, 2013 decision does not prevent EPA from redesignating the West
Virginia portion of the Martinsburg Area to attainment for the 1997
annual PM2.5 NAAQS. Even in light of the D.C. Circuit
Court's decision, redesignation for this Area is appropriate under the
CAA and EPA's longstanding interpretations of the CAA's provisions
regarding redesignation. EPA first explains its longstanding
interpretation that requirements that are imposed, or that become due,
after a complete redesignation request is submitted for an area that is
attaining the standard, are not applicable for purposes of evaluating a
redesignation request. Second, EPA then shows that, even if EPA applies
the subpart 4 requirements to the West Virginia redesignation request
and disregards the provisions of its 1997 PM2.5
Implementation Rule recently remanded by the D.C. Circuit Court, the
State's request for redesignation of the Area still qualifies for
approval. EPA's discussion takes into account the effect of the D.C.
Circuit Court's ruling and EPA's proposed PM2.5 Subpart 4
Classification and Deadline Rule on the Area's maintenance plan, which
EPA views as approvable when subpart 4 requirements are considered.
a. Applicable Requirements for Purposes of Evaluating the Redesignation
Request
With respect to the 1997 PM2.5 Implementation Rule, the
D.C. Circuit Court's January 4, 2013 ruling rejected EPA's reasons for
implementing the PM2.5 NAAQS solely in accordance with the
provisions of subpart 1, and remanded that matter to EPA, so that it
could address implementation of the 1997 annual PM2.5 NAAQS
under subpart 4 of Part D of the CAA, in addition to subpart 1. For the
purposes of evaluating West Virginia's redesignation request for the
West Virginia portion of the Martinsburg Area, to the extent that
implementation under subpart 4 would impose additional requirements for
areas designated nonattainment, EPA believes that those requirements
are not ``applicable'' for the purposes of section 107(d)(3)(E) of the
CAA, and thus EPA is not required to consider subpart 4 requirements
with respect to the redesignation of the West Virginia portion of the
Martinsburg Area. Under its longstanding interpretation of the CAA, EPA
has interpreted section 107(d)(3)(E) to mean, as a threshold matter,
that the part D provisions which are ``applicable'' and which must be
approved in order for EPA to redesignate an area include only those
which came due prior to a state's submittal of a complete redesignation
request. See 1992 Calcagni Memorandum. See also ``SIP Requirements for
Areas Submitting Requests for Redesignation to Attainment of the Ozone
and Carbon Monoxide (CO) NAAQS on or after November 15, 1992,''
Memorandum from Michael Shapiro, Acting Assistant Administrator, Air
and Radiation, September 17, 1993 (Shapiro memorandum); Final
Redesignation of Detroit-Ann Arbor, (60 FR 12459, 12465-66, March 7,
1995); Final Redesignation of St. Louis, Missouri, (68 FR 25418, 25424-
27, May 12, 2003); Sierra Club v. EPA, 375 F.3d 537, 541 (7th Cir.
2004) (upholding EPA's redesignation rulemaking applying this
interpretation and expressly rejecting Sierra Club's view that the
meaning of ``applicable'' under the statute is ``whatever should have
been in the plan at the time of attainment rather than whatever
actually was in the plan and already implemented or due at the time of
attainment'').\1\ In this case, at the time that West Virginia
submitted its redesignation request for the 1997 PM2.5
NAAQS, the requirements under subpart 4 were not due.
---------------------------------------------------------------------------
\1\ Applicable requirements of the CAA that come due subsequent
to the area's submittal of a complete redesignation request remain
applicable until a redesignation is approved, but are not required
as a prerequisite to redesignation. Section 175A(c) of the CAA.
---------------------------------------------------------------------------
EPA's view that, for purposes of evaluating the redesignation of
the West Virginia portion of the Martinsburg Area, the subpart 4
requirements were not due at the time West Virginia submitted the
redesignation request is in keeping with the EPA's interpretation of
subpart 2 requirements for subpart 1 ozone areas redesignated
subsequent to the D.C. Circuit Court's decision in South Coast Air
Quality Mgmt. Dist. v. EPA, 472 F.3d 882 (D.C. Cir. 2006). In South
Coast, the D.C. Circuit Court found that EPA was not permitted to
implement the 1997 8-hour ozone standard solely under subpart 1, and
held that EPA was required under the statute to implement the standard
under the ozone-specific requirements of subpart 2 as well. Subsequent
to the
[[Page 25545]]
South Coast decision, in evaluating and acting upon redesignation
requests for the 1997 8-hour ozone standard that were submitted to EPA
for areas under subpart 1, EPA applied its longstanding interpretation
of the CAA that ``applicable requirements,'' for purposes of evaluating
a redesignation, are those that had been due at the time the
redesignation request was submitted. See, e.g., Proposed Redesignation
of Manitowoc County and Door County Nonattainment Areas (75 FR 22047,
22050, April 27, 2010). In those rulemaking actions, EPA therefore, did
not consider subpart 2 requirements to be ``applicable'' for the
purposes of evaluating whether the area should be redesignated under
section 107(d)(3)(E) of the CAA.
EPA's interpretation derives from the provisions of section
107(d)(3) of the CAA. Section 107(d)(3)(E)(v) states that, for an area
to be redesignated, a state must meet ``all requirements `applicable'
to the area under section 110 and part D.'' Section 107(d)(3)(E)(ii)
provides that EPA must have fully approved the ``applicable'' SIP for
the area seeking redesignation. These two sections read together
support EPA's interpretation of ``applicable'' as only those
requirements that came due prior to submission of a complete
redesignation request.
First, holding states to an ongoing obligation to adopt new CAA
requirements that arose after the state submitted its redesignation
request, in order to be redesignated, would make it problematic or
impossible for EPA to act on redesignation requests in accordance with
the 18-month deadline Congress set for EPA action in section
107(d)(3)(D). If ``applicable requirements'' were interpreted to be a
continuing flow of requirements with no reasonable limitation, states,
after submitting a redesignation request, would be forced continuously
to make additional SIP submissions that in turn would require EPA to
undertake further notice-and-comment rulemaking actions to act on those
submissions. This would create a regime of unceasing rulemaking that
would delay action on the redesignation request beyond the 18-month
timeframe provided by the CAA for this purpose.
Second, a fundamental premise for redesignating a nonattainment
area to attainment is that the area has attained the relevant NAAQS due
to emission reductions from existing controls. Thus, an area for which
a redesignation request has been submitted would have already attained
the NAAQS as a result of satisfying statutory requirements that came
due prior to the submission of the request. Absent a showing that
unadopted and unimplemented requirements are necessary for future
maintenance, it is reasonable to view the requirements applicable for
purposes of evaluating the redesignation request as including only
those SIP requirements that have already come due. These are the
requirements that led to attainment of the NAAQS. To require, for
redesignation approval, that a state also satisfy additional SIP
requirements coming due after the state submits its complete
redesignation request, and while EPA is reviewing it, would compel the
state to do more than is necessary to attain the NAAQS, without a
showing that the additional requirements are necessary for maintenance.
In the context of this redesignation, the timing and nature of the
D.C. Circuit Court's January 4, 2013 decision in NRDC v. EPA and EPA's
November 21, 2013 proposed PM2.5 Subpart 4 Classification
and Deadline Rule, compound the consequences of imposing requirements
that come due after the redesignation request is submitted. West
Virginia submitted its redesignation request for the 1997 annual
PM2.5 NAAQS on August 5, 2013 for the West Virginia portion
of the Martinsburg Area, which is prior to the deadline by which the
Area is required to meet the applicable requirements pursuant to
subpart 4.
To require West Virginia's fully-completed and pending
redesignation request for the 1997 annual PM2.5 NAAQS to
comply now with requirements of subpart 4 that the D.C. Circuit Court
announced only in January 2013 and for which the deadline to comply has
not yet come, would be to give retroactive effect to such requirements
and provide West Virginia a unique and earlier deadline for compliance
solely on the basis of submitting a redesignation request for the West
Virginia portion of the Martinsburg Area. The D.C. Circuit Court
recognized the inequity of this type of retroactive impact in Sierra
Club v. Whitman, 285 F.3d 63 (D.C. Cir. 2002),\2\ where it upheld the
D.C. Circuit Court's ruling refusing to make retroactive EPA's
determination that the Area did not meet its attainment deadline. In
that case, petitioners urged the D.C. Circuit Court to make EPA's
nonattainment determination effective as of the date that the statute
required, rather than the later date on which EPA actually made the
determination. The D.C. Circuit Court rejected this view, stating that
applying it ``would likely impose large costs on States, which would
face fines and suits for not implementing air pollution prevention
plans . . . even though they were not on notice at the time.'' Id. at
68. Similarly, it would be unreasonable to penalize the State of West
Virginia by rejecting its redesignation request for an area that is
already attaining the 1997 annual PM2.5 NAAQS and that met
all applicable requirements known to be in effect at the time of the
requests. For EPA now to reject the redesignation request solely
because West Virginia did not expressly address subpart 4 requirements
which have not yet come due and for which it had little to no notice,
would inflict the same unfairness condemned by the D.C. Circuit Court
in Sierra Club v. Whitman.
---------------------------------------------------------------------------
\2\ Sierra Club v. Whitman was discussed and distinguished in a
recent D.C. Circuit Court decision that addressed retroactivity in a
quite different context, where, unlike the situation here, EPA
sought to give its regulations retroactive effect. National
Petrochemical and Refiners Ass'n v. EPA. 630 F.3d 145, 163 (D.C.
Cir. 2010), rehearing denied 643 F.3d 958 (D.C. Cir. 2011), cert
denied 132 S. Ct. 571 (2011).
---------------------------------------------------------------------------
b. Subpart 4 Requirements and West Virginia Redesignation Request
Even if EPA were to take the view that the D.C. Circuit Court's
January 4, 2013 decision requires that, in the context of pending
redesignations for the 1997 annual PM2.5 NAAQS, subpart 4
requirements were due and in effect at the time West Virginia submitted
its redesignation request, EPA proposes to determine that the West
Virginia portion of the Martinsburg Area still qualifies for
redesignation to attainment for the 1997 annual PM2.5 NAAQS.
As explained subsequently, EPA believes that the redesignation request
for the West Virginia portion of the Martinsburg Area, though not
expressed in terms of subpart 4 requirements, substantively meets the
requirements of that subpart for purposes of redesignating the Area to
attainment for the 1997 annual PM2.5 NAAQS.
With respect to evaluating the relevant substantive requirements of
subpart 4 for purposes of redesignating the West Virginia portion of
the Martinsburg Area, EPA notes that subpart 4 incorporates components
of subpart 1 of part D, which contains general air quality planning
requirements for areas designated as nonattainment. See section 172(c).
Subpart 4 itself contains specific planning and scheduling requirements
for coarse particulate matter (PM10) \3\ nonattainment
areas, and under the D.C. Circuit Court's January 4, 2013 decision in
NRDC v. EPA, these same statutory
[[Page 25546]]
requirements also apply for PM2.5 nonattainment areas. EPA
has longstanding general guidance that interprets the 1990 amendments
to the CAA, making recommendations to states for meeting the statutory
requirements for SIPs for nonattainment areas. See, the General
Preamble. In the General Preamble, EPA discussed the relationship of
subpart 1 and subpart 4 SIP requirements, and pointed out that subpart
1 requirements were to an extent ``subsumed by, or integrally related
to, the more specific PM10 requirements'' (57 FR 13538,
April 16, 1992). The subpart 1 requirements include, among other
things, provisions for attainment demonstrations, RACM, RFP, emissions
inventories, and contingency measures.
---------------------------------------------------------------------------
\3\ PM10 refers to particulates nominally 10
micrometers in diameter or smaller.
---------------------------------------------------------------------------
For the purposes of this redesignation request, in order to
identify any additional requirements which would apply under subpart 4,
consistent with EPA's November 21, 2013 proposed PM2.5
Subpart 4 Classification and Deadline Rule, EPA is considering the
Martinsburg Area to be a ``moderate'' PM2.5 nonattainment
area. As EPA explained in its November 21, 2013 proposed rule, section
188 of the CAA provides that all areas designated nonattainment areas
under subpart 4 are initially classified by operation of law as
``moderate'' nonattainment areas, and remain moderate nonattainment
areas unless and until EPA reclassifies the area as a ``serious''
nonattainment area. Accordingly, EPA believes that it is appropriate to
limit the evaluation of the potential impact of subpart 4 requirements
to those that would be applicable to moderate nonattainment areas.
Sections 189(a) and (c) of subpart 4 apply to moderate nonattainment
areas and include the following: (1) An approved permit program for
construction of new and modified major stationary sources (section
189(a)(1)(A)); (2) an attainment demonstration (section 189(a)(1)(B));
(3) provisions for RACM (section 189(a)(1)(C)); and (4) quantitative
milestones demonstrating RFP toward attainment by the applicable
attainment date (section 189(c)).
The permit requirements of subpart 4, as contained in section
189(a)(1)(A), refer to and apply the subpart 1 permit provisions
requirements of sections 172 and 173 to PM10, without adding
to them. Consequently, EPA believes that section 189(a)(1)(A) does not
itself impose for redesignation purposes any additional requirements
for moderate areas beyond those contained in subpart 1.\4\ In any
event, in the context of redesignation, EPA has long relied on the
interpretation that a fully approved nonattainment NSR program is not
considered an applicable requirement for redesignation, provided the
area can maintain the standard with a prevention of significant
deterioration (PSD) program after redesignation. A 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 NSR Requirements for Areas Requesting Redesignation to
Attainment.'' See also rulemakings for Detroit, Michigan (60 FR 12467-
12468, March 7, 1995); Cleveland-Akron-Lorain, Ohio (61 FR 20458,
20469-20470, May 7, 1996); Louisville, Kentucky (66 FR 53665, October
23, 2001); and Grand Rapids, Michigan (61 FR 31834-31837, June 21,
1996).
---------------------------------------------------------------------------
\4\ The potential effect of section 189(e) on section
189(a)(1)(A) for purposes of evaluating this redesignation is
discussed in this rulemaking action.
---------------------------------------------------------------------------
With respect to the specific attainment planning requirements under
subpart 4,\5\ when EPA evaluates a redesignation request under either
subpart 1 and/or 4, any area that is attaining the PM2.5
NAAQS is viewed as having satisfied the attainment planning
requirements for these subparts. For redesignations, EPA has for many
years interpreted attainment-linked requirements as not applicable for
areas attaining the standard. In the General Preamble, EPA stated that:
``The requirements for RFP will not apply in evaluating a request for
redesignation to attainment since, at a minimum, the air quality data
for the area must show that the area has already attained. Showing that
the State will make RFP towards attainment will, therefore, have no
meaning at that point.''
---------------------------------------------------------------------------
\5\ I.e., attainment demonstration, RFP, RACM, milestone
requirements, contingency measures.
---------------------------------------------------------------------------
The General Preamble also explained that: ``[t]he section 172(c)(9)
requirements are directed at ensuring RFP and attainment by the
applicable date. These requirements no longer apply when an area has
attained the standard and is eligible for redesignation. Furthermore,
section 175A for maintenance plans . . . provides specific requirements
for contingency measures that effectively supersede the requirements of
section 172(c)(9) for these areas.'' Id. EPA similarly stated in its
1992 Calcagni Memorandum that, ``The requirements for reasonable
further progress and other measures needed for attainment will not
apply for redesignations because they only have meaning for areas not
attaining the standard.''
It is evident that even if we were to consider the D.C. Circuit
Court's January 4, 2013 decision in NRDC v. EPA to mean that
attainment-related requirements specific to subpart 4 should be imposed
retroactively \6\ or prior to December 13, 2014 and thus, were due
prior to West Virginia's redesignation request, those requirements do
not apply to an area that is attaining the 1997 annual PM2.5
NAAQS, for the purpose of evaluating a pending request to redesignate
the area to attainment. EPA has consistently enunciated this
interpretation of applicable requirements under section 107(d)(3)(E)
since the General Preamble was published more than twenty years ago.
Courts have recognized the scope of EPA's authority to interpret
``applicable requirements'' in the redesignation context. See Sierra
Club v. EPA, 375 F.3d 537 (7th Cir. 2004).
---------------------------------------------------------------------------
\6\ As EPA has explained above, we do not believe that the D.C.
Circuit Court's January 4, 2013 decision should be interpreted so as
to impose these requirements on the states retroactively. Sierra
Club v. Whitman, supra.
---------------------------------------------------------------------------
Moreover, even outside the context of redesignations, EPA has
viewed the obligations to submit attainment-related SIP planning
requirements of subpart 4 as inapplicable for areas that EPA determines
are attaining the1997 annual PM2.5 NAAQS. EPA's prior
``Clean Data Policy'' rulemakings for the PM10 NAAQS, also
governed by the requirements of subpart 4, explain EPA's reasoning.
They describe the effects of a determination of attainment on the
attainment-related SIP planning requirements of subpart 4. See
``Determination of Attainment for Coso Junction Nonattainment Area,''
(75 FR 27944, May 19, 2010). See also Coso Junction Proposed
PM10 Redesignation, (75 FR 36023, 36027, June 24, 2010);
Proposed and Final Determinations of Attainment for San Joaquin
Nonattainment Area (71 FR 40952, 40954-55, July 19, 2006; and 71 FR
63641, 63643-47, October 30, 2006). In short, EPA in this context has
also long concluded that to require states to meet superfluous SIP
planning requirements is not necessary and not required by the CAA, so
long as those areas continue to attain the relevant NAAQS. Elsewhere in
this notice, EPA determined that the Martinsburg Area has attained the
1997 annual PM2.5 NAAQS. Under its longstanding
interpretation, EPA is proposing to determine here that the West
Virginia portion of the Area meets the attainment-related plan
requirements of subparts 1 and 4 for the 1997 annual PM2.5
NAAQS. Thus, EPA
[[Page 25547]]
is proposing to conclude that the requirements to submit an attainment
demonstration under 189(a)(1)(B), a RACM determination under section
172(c)(1) and section 189(a)(1)(c), a RFP demonstration under
189(c)(1), and contingency measure requirements under section 172(c)(9)
are satisfied for purposes of evaluating this redesignation request.
c. Subpart 4 and Control of PM2.5 Precursors
The D.C. Circuit Court in NRDC v. EPA remanded to EPA the two rules
at issue in the case with instructions to EPA to re-promulgate them
consistent with the requirements of subpart 4. EPA in this section
addresses the D.C. Circuit Court's opinion with respect to
PM2.5 precursors. While past implementation of subpart 4 for
PM10 has allowed for control of PM10 precursors
such as NOX from major stationary, mobile, and area sources
in order to attain the standard as expeditiously as practicable,
section 189(e) of the CAA specifically provides that control
requirements for major stationary sources of direct PM10
shall also apply to PM10 precursors from those sources,
except where EPA determines that major stationary sources of such
precursors ``do not contribute significantly to PM10 levels
which exceed the standard in the area.''
EPA's 1997 PM2.5 Implementation Rule, remanded by the
D.C. Circuit Court, contained rebuttable presumptions concerning
certain PM2.5 precursors applicable to attainment plans and
control measures related to those plans. Specifically, in 40 CFR
51.1002, EPA provided, among other things, that a state was ``not
required to address VOC [and NH3] as . . . PM2.5
attainment plan precursor[s] and to evaluate sources of VOC [and
NH3] emissions in the State for control measures.'' EPA
intended these to be rebuttable presumptions. EPA established these
presumptions at the time because of uncertainties regarding the
emission inventories for these pollutants and the effectiveness of
specific control measures in various regions of the country in reducing
PM2.5 concentrations. EPA also left open the possibility for
such regulation of VOC and NH3 in specific areas where that
was necessary.
The D.C. Circuit Court in its January 4, 2013 decision made
reference to both section 189(e) and 40 CFR 51.1002, and stated that,
``In light of our disposition, we need not address the petitioners'
challenge to the presumptions in [40 CFR 51.1002] that VOCs and
NH3 are not PM2.5 precursors, as subpart 4
expressly governs precursor presumptions.'' NRDC v. EPA, at 27, n.10.
Elsewhere in the D.C. Circuit Court's opinion, however, the D.C.
Circuit Court observed: ``NH3 is a precursor to fine
particulate matter, making it a precursor to both PM2.5 and
PM10. For a PM10 nonattainment area governed by
subpart 4, a precursor is presumptively regulated. See 42 U.S.C.
7513a(e) [section 189(e)].'' Id. at 21, n.7.
For a number of reasons, EPA believes that its proposed
redesignation of the West Virginia portion of the Martinsburg Area for
the 1997 annual PM2.5 NAAQS are consistent with the D.C.
Circuit Court's decision on this aspect of subpart 4. First, while the
D.C. Circuit Court, citing section 189(e), stated that ``for a
PM10 area governed by subpart 4, a precursor is
`presumptively' regulated,'' the D.C. Circuit Court expressly declined
to decide the specific challenge to EPA's 1997 PM2.5
Implementation Rule provisions regarding NH3 and VOC as
precursors. The D.C. Circuit Court had no occasion to reach whether and
how it was substantively necessary to regulate any specific precursor
in a particular PM2.5 nonattainment area, and did not
address what might be necessary for purposes of acting upon a
redesignation request.
However, even if EPA takes the view that the requirements of
subpart 4 were deemed applicable at the time the state submitted the
redesignation request, and disregards the 1997 PM2.5
Implementation Rule's rebuttable presumptions regarding NH3
and VOC as PM2.5 precursors, the regulatory consequence
would be to consider the need for regulation of all precursors from any
sources in the Area to demonstrate attainment and to apply the section
189(e) provisions to major stationary sources of precursors. In the
case of the West Virginia portion of the Martinsburg Area, EPA believes
that doing so is consistent with proposing redesignation of the West
Virginia portion of the Area for the 1997 annual PM2.5
NAAQS. The West Virginia portion of the Area has attained the 1997
annual PM2.5 NAAQS without any specific additional controls
of NH3 and VOC and emissions from any sources in the Area.
Precursors in subpart 4 are specifically regulated under the
provisions of section 189(e), which requires, with important
exceptions, control requirements for major stationary sources of
PM10 precursors.\7\ Under subpart 1 and EPA's prior
implementation rule, all major stationary sources of PM2.5
precursors were subject to regulation, with the exception of
NH3 and VOC. Thus we must address here whether additional
controls of NH3 and VOC from major stationary sources are
required under section 189(e) of subpart 4 in order to redesignate the
Area for the 1997 annual PM2.5 NAAQS. As explained
subsequently, we do not believe that any additional controls of
NH3 and VOC are required in the context of this
redesignation.
---------------------------------------------------------------------------
\7\ Under either subpart 1 or subpart 4, for purposes of
demonstrating attainment as expeditiously as practicable, a state is
required to evaluate all economically and technologically feasible
control measures for direct PM emissions and precursor emissions,
and adopt those measures that are deemed reasonably available.
---------------------------------------------------------------------------
In the General Preamble, EPA discusses its approach to implementing
section 189(e). See 57 FR 13538-13542. With regard to precursor
regulation under section 189(e), the General Preamble explicitly stated
that control of VOC under other CAA requirements may suffice to relieve
a state from the need to adopt precursor controls under section 189(e).
See 57 FR 13542. EPA in this rulemaking action, proposes to determine
that West Virginia's SIP has met the provisions of section 189(e) with
respect to NH3 and VOC as precursors. This proposed
determination is based on our findings that: (1) The Martinsburg Area
contains no major stationary sources of NH3, and (2)
existing major stationary sources of VOC are adequately controlled
under other provisions of the CAA regulating the ozone NAAQS.\8\ In the
alternative, EPA proposes to determine that, under the express
exception provisions of section 189(e), and in the context of the
redesignation of the West Virginia portion of the Martinsburg Area,
which is attaining the 1997 annual PM2.5 NAAQS, at present
NH3 and VOC precursors from major stationary sources do not
contribute significantly to levels exceeding the 1997 annual
PM2.5 NAAQS in the Area. See 57 FR 13539-42.
---------------------------------------------------------------------------
\8\ The Martinsburg Area has reduced VOC emissions through the
implementation of various control programs including VOC Reasonably
Available Control Technology (RACT) regulations and various on-road
and non-road motor vehicle control programs.
---------------------------------------------------------------------------
EPA notes that its 1997 PM2.5 Implementation Rule
provisions in 40 CFR 51.1002 were not directed at evaluation of
PM2.5 precursors in the context of redesignation, but at SIP
plans and control measures required to bring a nonattainment area into
attainment of the 1997 annual PM2.5 NAAQS. By contrast,
redesignation to attainment primarily requires the nonattainment area
to have already
[[Page 25548]]
attained due to permanent and enforceable emission reductions, and to
demonstrate that controls in place can continue to maintain the
standard. Thus, even if we regard the D.C. Circuit Court's January 4,
2013 decision as calling for ``presumptive regulation'' of
NH3 and VOC for PM2.5 under the attainment
planning provisions of subpart 4, those provisions in and of themselves
do not require additional controls of these precursors for an area that
already qualifies for redesignation. Nor does EPA believe that
requiring West Virginia to address precursors differently than it has
already would result in a substantively different outcome.
Although, as EPA has emphasized, its consideration here of
precursor requirements under subpart 4 is in the context of a
redesignation to attainment, EPA's existing interpretation of subpart 4
requirements with respect to precursors in attainment plans for
PM10 contemplates that states may develop attainment plans
that regulate only those precursors that are necessary for purposes of
attainment in the area in question, i.e., states may determine that
only certain precursors need be regulated for attainment and control
purposes.\9\ Courts have upheld this approach to the requirements of
subpart 4 for PM10.\10\ EPA believes that application of
this approach to PM2.5 precursors under subpart 4 is
reasonable. Because the Martinsburg Area has already attained the 1997
annual PM2.5 NAAQS with its current approach to regulation
of PM2.5 precursors, EPA believes that it is reasonable to
conclude in the context of this redesignation that there is no need to
revisit the attainment control strategy with respect to the treatment
of precursors. Even if the D.C. Circuit Court's decision is construed
to impose an obligation, in evaluating this redesignation request, to
consider additional precursors under subpart 4, it would not affect
EPA's approval here of West Virginia's request for redesignation of the
Martinsburg Area for the 1997 annual PM2.5 NAAQS. In the
context of a redesignation, the Area has shown that it has attained the
standards. Moreover, West Virginia has shown and EPA has proposed to
determine that attainment of the 1997 annual PM2.5 NAAQS in
this Area is due to permanent and enforceable emissions reductions on
all precursors necessary to provide for continued attainment of the
standards. It follows logically that no further control of additional
precursors is necessary. Accordingly, EPA does not view the January 4,
2013 decision of the D.C. Circuit Court as precluding redesignation of
the West Virginia portion of the Martinsburg Area to attainment for the
1997 annual PM2.5 NAAQS at this time.
---------------------------------------------------------------------------

Plans for California--San Joaquin Valley PM10
Nonattainment Area; Serious Area Plan for Nonattainment of the 24-
Hour and Annual PM10 Standards,'' (69 FR 30006, May 26,
2004) (approving a PM10 attainment plan that impose
controls on direct PM10 and NOX emissions and
did not impose controls on SO2, VOC, or NH3
emissions).
\10\ See, e.g., Assoc. of Irritated Residents v. EPA et al., 423
F.3d 989 (9th Cir. 2005).
---------------------------------------------------------------------------
In summary, even if, prior to the date of the redesignation request
submittal, West Virginia was required to address precursors for the
Martinsburg Area under subpart 4 rather than under subpart 1, as
interpreted in EPA's remanded 1997 PM2.5 Implementation
Rule, EPA would still conclude that the West Virginia portion of the
Martinsburg Area had met all applicable requirements for purposes of
redesignation in accordance with section 107(d)(3)(E)(ii) and (v) of
the CAA.
V. EPA's Analysis of West Virginia's SIP Submittal
EPA is proposing several rulemaking actions for the West Virginia
portion of the Martinsburg Area: (1) To redesignate the Area to
attainment for the 1997 annual PM2.5 NAAQS; (2) to approve
into the West Virginia SIP, the associated maintenance plan for the
1997 annual PM2.5 NAAQS; and (3) to approve the 2007
comprehensive emissions inventory into the West Virginia SIP to satisfy
section 172(c)(3) of the CAA requirement for the Area, one of the
criteria for redesignation. EPA's proposed approvals of the
redesignation request and maintenance plan for the 1997 annual
PM2.5 NAAQS are based upon EPA's determination that the Area
continues to attain the 1997 annual PM2.5 NAAQS, which EPA
is proposing in this rulemaking action, and that all other
redesignation criteria have been met for the West Virginia portion of
the Area. In addition, EPA is proposing to approve the 2017 and 2025
MVEBs for Berkeley County, West Virginia for transportation conformity
purposes. The following is a description of how the West Virginia's
August 5, 2013 submittal satisfies the requirements of section
107(d)(3)(E) of the CAA for the 1997 annual PM2.5 NAAQS.
A. Redesignation Request
1. Attainment
As noted previously, in the final rulemaking action dated January
10, 2012 (77 FR 1411), EPA determined that the entire Martinsburg Area
had attained the 1997 annual PM2.5 NAAQS. This determination
of attainment was based upon complete, quality-assured and certified
ambient air quality monitoring data for the period of 2007-2009 showing
that the Area had attained the 1997 annual PM2.5 NAAQS by
its applicable attainment date of April 5, 2010. On November 20, 2009
(74 FR 60199), EPA determined that the Martinsburg Area had clean data
for the 1997 annual PM2.5 NAAQS. The determination was based
upon complete, quality assured, and certified ambient air monitoring
date showing that this Area has monitored attainment of the 1997 annual
PM2.5 NAAQS based on the 2006-2008 data and data available
to date for 2012 in EPA's Air Quality System (AQS) database. Further
discussion of pertinent air quality issues underlying this
determination was provided in the notice of proposed rulemaking for
EPA's determination of attainment for this Area, published on September
29, 2009 (74 FR 49833) for the 1997 annual PM2.5 NAAQS.
EPA has reviewed the ambient air quality PM2.5
monitoring data in the Martinsburg Area consistent with the
requirements contained at 40 CFR part 50, and recorded in EPA's AQS
database. To support the previous determinations of attainment of the
Area, EPA has also reviewed more recent data in its AQS database,
including certified, quality-assured data for the period from 2008-
2010, 2009-2011 and 2010-2012. This data, shown in Table 1, shows that
the Martinsburg Area continues to attain the 1997 annual
PM2.5 NAAQS. In addition, as discussed subsequently with
respect to the maintenance plan, WVDEP has committed to continue
monitoring ambient PM2.5 concentrations in accordance with
40 CFR part 58. Thus, EPA is proposing to determine that the
Martinsburg Area continues to attain the 1997 PM2.5 NAAQS.

2. The Area Has Met All Applicable Requirements Under Section 110 and
Subpart 1 of the CAA and Has a Fully Approved SIP Under Section 110(k)
of the CAA
In accordance with section 107(d)(3)(E)(v) of the CAA, the SIP
revisions for the 1997 annual PM2.5 NAAQS for the West
Virginia portion of the Martinsburg Area must be fully approved under
section 110(k) of the CAA and all the requirements applicable to the
Area under section 110 of the CAA (general SIP requirements) and part D
of Title I of the CAA (SIP requirements for nonattainment areas) must
be met.
a. Section 110 General SIP Requirements
Section 110(a)(2) of Title I of the CAA delineates the general
requirements for a SIP, which include enforceable emissions limitations
and other control measures, means, or techniques, provisions for the
establishment and operation of appropriate devices necessary to collect
data on ambient air quality, and programs to enforce the limitations.
The general SIP elements and requirements set forth in section
110(a)(2) of the CAA include, but are not limited to the following: (1)
Submittal of a SIP that has been adopted by the state after reasonable
public notice and hearing; (2) provisions for establishment and
operation of appropriate procedures needed to monitor ambient air
quality; (3) implementation of a source permit program; provisions for
the implementation of Part C requirements (PSD); (4) provisions for the
implementation of Part D requirements for NSR permit programs; (5)
provisions for air pollution modeling; and (6) provisions for public
and local agency participation in planning and emission control rule
development.
Section 110(a)(2)(D) of the CAA 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 in accordance with the
NOX SIP Call (63 FR 57356, October 27, 1998), amendments to
the NOX SIP Call (64 FR 26298, May 14, 1999 and 65 FR 11222,
March 2, 2000), and CAIR (70 FR 25162, May 12, 2005). However, 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 these requirements
are applicable requirements for purposes of redesignation.
In addition, EPA believes that the other section 110(a)(2) elements
of the CAA not connected with nonattainment plan submissions and not
linked with an area's attainment status are not applicable requirements
for purposes of redesignation. The Martinsburg Area will still be
subject to these requirements after it is redesignated. EPA concludes
that section 110(a)(2) of the CAA 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, and
that section 110(a)(2) elements of the CAA not linked in the area's
nonattainment status are not applicable for purposes of redesignation.
This approach is consistent with EPA's existing policy on applicability
of conformity (i.e., for redesignations) and oxygenated fuels
requirement. See Reading, Pennsylvania, proposed and final rulemakings
(61 FR 53174, October 10, 1996), (62 FR 24826, May 7, 1997); Cleveland-
Akron-Lorain, Ohio final rulemaking (61 FR 20458, May 7, 1996); and
Tampa, Florida final rulemaking (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 53099, October 19, 2001).
EPA has reviewed the West Virginia SIP and has concluded that it
meets the general SIP requirements under section 110(a)(2) of the CAA
to the extent they are applicable for purposes of redesignation. EPA
has previously approved provisions of West Virginia's SIP addressing
section 110(a)(2) requirements, including provisions addressing
PM2.5. See (76 FR 47062, August 4, 2011). These requirements
are, however, statewide requirements that are not linked to the
PM2.5 nonattainment status of the Martinsburg Area.
Therefore, EPA believes that these SIP elements are not applicable
requirements for purposes of review of West Virginia's PM2.5
redesignation request.
b. Subpart 4 Requirements
Subpart 1 sets forth the basic nonattainment plan requirements
applicable to PM2.5 nonattainment areas. Under section 172
of the CAA, states with nonattainment areas must submit plans providing
for timely attainment and meet a variety of other requirements.
The General Preamble for Implementation of Title I discusses the
evaluation of these requirements in the context of EPA's consideration
of a redesignation request. The General Preamble sets forth EPA's view
of applicable requirements for purposes of evaluating redesignation
requests when an area is attaining the standard. See 57 FR 13498 (April
16, 1992).
As noted previously, EPA has determined that the Martinsburg Area
has attained the 1997 annual PM2.5 NAAQS. Pursuant to 40 CFR
51.2004(c), the requirement for West Virginia to submit for the West
Virginia portion of the Martinsburg Area an attainment demonstration
and associated RACM, an RFP plan, contingency measures, and other
planning SIPs related to the attainment of the 1997 annual
PM2.5 NAAQS are suspended until the Area is redesignated to
attainment for the standard, or EPA determines that the Area again
violated the standard, at which time such plans are required to
[[Page 25550]]
be submitted. Since the Area has reached attainment for the 1997 annual
PM2.5 NAAQS and continues to attain the standard, no
additional measures are needed to provide for attainment. Therefore,
the requirements of sections 172(c)(1), 172(c)(2), 172(c)(6), and
172(c)(9) of the CAA are no longer considered to be applicable for
purposes of redesignation of the Area for the 1997 annual
PM2.5 NAAQS.
Section 172(c)(3) of the CAA requires submission and approval of a
comprehensive, accurate and current inventory of actual emissions. As a
result of EPA's determination of attainment of the Area for the 1997
annual PM2.5 NAAQS, in which certain planning requirements
were suspended for the standard, the only remaining requirement under
section 172 of the CAA to be considered for purposes of redesignation
of the Area is the comprehensive emissions inventory required under
section 172(c)(3) of the CAA. As part of West Virginia's August 5, 2013
submittal, the State submitted a 2007 base year emissions inventory for
the West Virginia portion of the Martinsburg Area for the 1997 annual
PM2.5 NAAQS which includes emissions estimates that cover
the general source categories of point sources, nonroad mobile sources,
area sources and on-road mobile sources. The pollutants that comprise
the inventory are NOX, VOCs, PM2.5,
NH3, and SO2.
In this rulemaking action, EPA is proposing to approve West
Virginia's 2007 base year emissions inventory in accordance with
section 172(c)(3) of the CAA. Final approval of the 2007 base year
emissions inventory will satisfy the emissions inventory requirement
under section 172(c)(3) of the CAA. For more information on the
evaluation and EPA's analysis of the 2007 base year emissions
inventory, see Appendix B of the State submittal and the emissions
inventory technical support document (TSD) dated January 14, 2014,
available on line at www.regulations.gov, Docket ID No. EPA-OAR-R03-
2013-0690. A summary of the 2007 base year emissions inventory is shown
in Table 2.

----------------------------------------------------------------------------------------------------------------
Section 172(c)(4) of the CAA requires the identification and
quantification of allowable emissions for major new and modified
stationary sources in an area, and section 172(c)(5) of the CAA
requires source permits for the construction and operation of new and
modified major stationary sources anywhere in the nonattainment area.
EPA has determined that, since the PSD requirements will apply after
redesignation, areas being redesignated need not comply with the
requirement that a nonattainment NSR program be approved prior to
redesignation, provided that the area demonstrates maintenance of the
NAAQS without part D NSR. 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 NSR
Requirements for Areas Requesting Redesignation to Attainment.''
Nevertheless, West Virginia currently has an approved NSR program,
codified in 45 CSR 19. See 71 FR 64468 (November 2, 2006) (approving
NSR program into the SIP). See also 77 FR 63736 (October 17, 2012)
(approving revisions to West Virginia's PSD program). However, West
Virginia's PSD program for the 1997 annual PM2.5 NAAQS will
become effective in the Martinsburg Area upon redesignation to
attainment.
Section 172(c)(7) of the CAA requires the SIP to meet the
applicable provisions of section 110(a)(2) of the CAA. As noted
previously, EPA believes the West Virginia SIP meets the requirements
of section 110(a)(2) of the CAA that are applicable for purposes of
redesignation.
Section 175A of the CAA requires a state seeking redesignation to
attainment to submit a SIP revision to provide for the maintenance of
the NAAQS in the area ``for at least 10 years after the
redesignation.'' In conjunction with its request to redesignate the
West Virginia portion of the Martinsburg Area to attainment status,
West Virginia submitted SIP revisions to provide for maintenance of the
1997 annual PM2.5 NAAQS in the Area for at least 10 years
after redesignation, throughout 2025. West Virginia is requesting that
EPA approve this SIP revision as meeting the requirement of section
175A of the CAA. Once approved, the maintenance plan for the West
Virginia portion of the Martinsburg Area will ensure that the SIP for
West Virginia meets the requirements of the CAA regarding maintenance
of the 1997 annual PM2.5 NAAQS for the Area. EPA's analysis
of the maintenance plan is provided in section V.B. of today's proposed
rulemaking action.
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 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
which EPA promulgated pursuant to its authority under the CAA. EPA
interprets the conformity SIP requirements as not applying for purposes
of evaluating the redesignation request under section 107(d) of the CAA
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)
[[Page 25551]]
(upholding this interpretation). See also 60 FR 62748 (December 7,
1995) (discussing Tampa, Florida).
Thus, for purposes of redesignating to attainment the Martinsburg
Area for the 1997 annual PM2.5 NAAQS, EPA determines that
the Area has met all applicable SIP requirements under part D of Title
I of the CAA. EPA also determines that upon final approval of the 2007
comprehensive emissions inventory as proposed in this rulemaking
action, the Martinsburg Area will also meet all applicable SIP
requirements under part D of Title I of the CAA for purposes of
redesignating the Area to attainment for the 1997 annual
PM2.5 NAAQS.
c. The West Virginia Portion of the Martinsburg Area Has a Fully
Approved Applicable SIP Under Section 110(k) of the CAA
For purposes of redesignation to attainment for the 1997 annual
PM2.5 NAAQS, EPA has fully approved all applicable
requirements of the West Virginia SIP for the Area in accordance with
section 110(k) of the CAA. Upon final approval of the 2007
comprehensive emissions inventory proposed in this rulemaking action,
EPA will have fully SIP-approved all applicable requirements of the
West Virginia SIP for the Area for purposes of redesignaton to
attainment for the 1997 annual PM2.5 NAAQS in accordance
with section 110(k) of the CAA.
3. Permanent and Enforceable Reductions in Emissions
For redesignating a nonattainment area to attainment, section
107(d)(3)(E)(iii) of 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 and
applicable Federal air pollution control regulations and other
permanent and enforceable reductions.
In making this demonstration, West Virginia has calculated the
change in emissions between 2005, one of the years used to designate
the Area as nonattainment, and 2007, one of the years the Area
monitored attainment as provided in Table 3. Sectors included in Table
3 are point, including airports; area; locomotive and marine (LM);
nonroad; fire; and onroad. There are no EGUs located in Berkeley
County. The reduction in emissions and the corresponding improvement in
air quality from 2005 to 2007 in the Martinsburg Area can be attributed
to a number of regulatory control measures that have been implemented
in the Area and contributing areas in recent years. For more
information on EPA's analysis of the 2005 and 2007 emissions inventory,
see EPA's emissions inventory TSD dated January 14, 2014, available in
the docket for this rulemaking action at www.regulations.gov. Docket ID
No. EPA-OAR-RO3-2013-0690.

a. Federal Measures Implemented
Reductions in PM2.5 precursor emissions have occurred
statewide and in upwind states as a result of Federal emission control
measures, with additional emission reductions expected to occur in the
future. The Tier 2 Emission Standards for Vehicles and Gasoline Sulfur
Standards (Tier 2 Standards) have resulted in lower NOX and
SO2 emissions from new cars and light duty trucks, including
sport utility vehicles. The Federal rules were phased in between 2004
and 2009. EPA has estimated that, after phasing in the new
requirements, new vehicles emit less NOX in the following
percentages: Passenger cars (light duty vehicles)--77 percent; light
duty trucks, minivans, and sports utility vehicles--86 percent; and
larger sports utility vehicles, vans, and heavier trucks--69-95
percent. EPA expects fleet wide average emissions to decline by similar
percentages as new vehicles replace older vehicles. The Tier 2
standards also reduced the sulfur content of gasoline to 30 parts per
million (ppm) beginning in January 2006, which reflects up to a 90
percent reduction in sulfur content.
EPA issued the Heavy-Duty Diesel Engine Rule in July 2000. 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 reduced PM2.5 emissions from heavy-duty highway
engines and further reduced the highway diesel fuel sulfur content to
15 ppm. The total program is estimated to achieve a 90 percent
reduction in direct PM2.5 emissions and a 95 percent
reduction in NOX emissions for these new engines using low
sulfur diesel, compared to existing engines using higher sulfur diesel
fuel. The reduction in fuel sulfur content also yielded an immediate
reduction in particulate sulfate emissions from all diesel vehicles.
In May 2004, EPA promulgated the Nonroad Diesel Rule for large
nonroad diesel engines, such as those used in construction,
agriculture, and mining, to be phased in between 2008 and 2014. The
rule also reduces the sulfur content in nonroad diesel fuel by over 99
percent. Prior to 2006, nonroad diesel fuel averaged approximately
3,400 ppm sulfur. This rule limited nonroad diesel sulfur content to
500 ppm by 2006, with a further reduction to 15 ppm by 2010.
As required by the CAA, EPA developed Maximum Available Control
Technology (MACT) Standards to regulate emissions of toxic air
pollutants from a published list of industrial sources referred to as
``source categories.'' The list of MACT source categories that must
meet control technology requirements to reduce the emission of toxic
air pollutants with compliance dates on or after 2005, is found in the
West Virginia's August 5, 2013 submittal on page 48, available on line
at www.regulations.gov, Docket ID No. EPA-OAR-R03-2013-0690.
b. State and Local Measures
EPA issued the NOX SIP Call in 1998 pursuant to the CAA
to require 22 states and the District of Columbia to reduce
NOX emissions from large EGUs and large non-EGUs such as
industrial boilers, internal combustion engines, and cement kilns. See
(63 FR 57356, October 27, 1998). EPA approved West Virginia's Phase I
NOX SIP Call rule on May 10, 2002 (67 FR 31733) and Phase II
rule on September 28, 2006 (71 FR 56881). Emission reductions resulting
from regulations developed in response to the NOX SIP Call
are permanent and enforceable.
On March 10, 2005, EPA issued CAIR, which applies to 27 states and
the District of Columbia. CAIR relied on 3 separate cap-and-trade
programs to reduce SO2 and NOX emissions. On
August 4, 2009 (74 FR 38536), EPA approved West Virginia's CAIR rules
into the West Virginia SIP. The maintenance plan for the Area for the
1997 annual PM2.5 NAAQS, thus, list CAIR as a control
measure for the purpose of reducing SO2 and NOX
emissions. On August 8, 2011 (76 FR 48208), EPA promulgated CSAPR to
replace CAIR, which has been in place since 2005. The D.C. Circuit
Court 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 21, 2012, the D.C.
Circuit Court issued a decision to vacate CSAPR. In that decision, it
also ordered EPA to continue administering CAIR ``pending the
promulgation of a valid replacement.'' EME Homer City, 696 F.3d at 38.
EPA and other parties have filed petitions for certiorari to the U.S.
Supreme Court, and on June 24, 2013, the Supreme Court granted
certiorari on EPA's petition for appeal of EME Homer City Generation.
See EME Homer City Generation, L.P. v. EPA, 696 F .3d 7 (D.C. Cir.
2012), cert. granted, 570 U.S.--(2013). Nonetheless, EPA intends to
continue to act in accordance with the EME Homer City opinion.
As noted earlier, EPA believes it is appropriate to allow states to
rely on the existing emissions reductions achieved by CAIR, as
sufficiently permanent and enforceable pending a valid replacement
rule, for purposes such as a redesignation. CAIR was in place and thus
getting emission reductions when the Martinsburg Area monitored
attainment of the 1997 annual PM2.5 NAAQS. The monitoring
data used to demonstrate the Area's attainment of the 1997 annual
PM2.5 NAAQS was impacted by CAIR. EPA finds West Virginia
appropriately included CAIR as a control measure in this SIP revision.
Furthermore, the air quality modeling analysis conducted for the
Transport Rule demonstrates that the Area would be able to attain the
1997 annual PM2.5 NAAQS even in the absence of either CAIR
or the Transport Rule. EPA's modeling projections show that all ambient
monitors in the Area are expected to continue to maintain compliance in
the 2012 and 2014 ``no CAIR'' base cases. Therefore, none of the
ambient monitoring sites in the Area are ``receptors'' that EPA
projects will have future nonattainment problems or difficulty
maintaining the NAAQS.
Based on the information summarized above, West Virginia has
adequately demonstrated that the improvement in air quality is due to
permanent and enforceable emissions reductions. The reductions result
from Federal requirements, regulation of precursors under the
NOX SIP Call, and CAIR, which are expected to continue into
the future.
B. Maintenance Plan
On August 5, 2013, WVDEP submitted a maintenance plan for the West
Virginia portion of the Martinsburg Area for the 1997 annual
PM2.5 NAAQS as required by section 175A of the CAA. EPA's
analysis for proposing approval of the maintenance plan is provided in
this section.
1. Attainment Emissions Inventory
An attainment inventory is comprised of the emissions during the
time period associated with the monitoring data showing attainment.
WVDEP developed emissions inventories for NOX,
PM2.5, SO2, VOC, and NH3 for 2007, one
of the years in the period during which the Martinsburg Area monitored
attainment of the 1997 annual PM2.5 standard, as described
previously.
WVDEP used the 2007 annual emissions inventory submitted to EPA's
National Emissions Inventory (NEI) database to compile their inventory.
There are no EGU's in Berkeley County. For the 2007 area source
emissions, WDEP used the Southern Modeling, Analysis, and Planning
(SEMAP) project.
[[Page 25553]]
For the 2007 nonroad mobile sources, WVDEP generated the emissions
using EPA's NONROAD model. The 2007 onroad mobile source inventory was
developed using the most current version of EPA's highway mobile source
emissions model MOVES2010a.
EPA has reviewed the documentation provided by WVDEP and found the
emissions inventory to be acceptable. For more information on EPA's
analysis of the 2007 emissions inventory, see Appendix B of the State
submittal and the emissions inventory TSD dated January 14, 2014,
available on line at www.regulations.gov, Docket ID No. EPA-OAR-R03-
2013-0690.
2. Maintenance Demonstration
Section 175A requires a state seeking redesignation to attainment
to submit a SIP revision to provide for the maintenance of the NAAQS in
the area ``for at least 10 years after the redesignation.'' EPA has
interpreted this as a showing of maintenance ``for a period of ten
years following redesignation.'' Where the emissions inventory method
of showing maintenance is used, its purpose is to show that emissions
during the maintenance period will not increase over the attainment
year inventory. See 1992 Calcagni Memorandum, pages 9-10.
For a demonstration of maintenance, emissions inventories are
required to be projected to future dates to assess the influence of
future growth and controls; however, the maintenance demonstration need
not be based on modeling. See Wall v. EPA, supra; Sierra Club v. EPA,
supra. See also 66 FR 53099-53100; 68 FR 25430-32. WVDEP uses
projection inventories to show that the Area will remain in attainment
and developed projection inventories for an interim year of 2017 and a
maintenance plan end year of 2025 to show that future emissions of
NOX, SO2, VOC, NH3, and
PM2.5 will remain at or below the attainment year 2007
emissions levels throughout the Martinsburg Area through the year 2025.
The projection inventories for the 2017 and 2025 point, area, and
nonroad sources were developed by the SEMAP contractors. Detailed
discussion of how projections were developed are contained in the
document ``SESARM Projection Year Final Report--Rev Jan 20 2013.pdf.''
Onroad mobile source projection inventories for Berkeley County were
prepared by Michael Baker Jr., Inc. and onroad mobile source emissions
for 2017 and 2025 were calculated from emission factors from MOVES2010
model runs. See Appendix C of the State submittal. EPA has reviewed the
documentation provided by WVDEP and found the methodologies acceptable.
EPA has determined that the emissions inventories that the 2017 and
2025 projected emissions inventories provided by WVDEP are approvable.
For more information on EPA's analysis of the emissions inventory, see
Appendix B of the State submittal and EPA's TSD dated January 14, 2014,
available on line at www.regulations.gov., Docket ID No. EPA-OAR-R03-
2013-0690. Table 4 provides the inventories for the 2007 attainment
year, the 2017 interim year, and the 2025 maintenance plan end year for
the Area.
Table 4--Comparison of 2007 Attainment Year and 2017 and 2025 Projected Emission Estimates for the Martinsburg
Area in tpy
----------------------------------------------------------------------------------------------------------------
SO2 NOX PM2.5 NH3 VOC
----------------------------------------------------------------------------------------------------------------
2007 (attainment)............... 9,016 19,254 2,455 1,522 8,109
2017 (interim).................. 7,629 12,086 2,188 1,485 5,668
2017 (projected decrease)....... 1,387 7,168 267 37 2,441
2025 (maintenance).............. 7,743 10,030 2,154 1,500 5,308
2025 (projected decrease)....... 1,273 9,224 301 23 2,802
----------------------------------------------------------------------------------------------------------------
Table 4 shows that between 2007 and 2017, the Area is projected to
reduce SO2 emissions by 1,387 tpy, NOX emissions
by 7,168 tpy, PM2.5 emissions by 267 tpy, NH3 by
37 tpy, and VOC by 2,441 tpy. Between 2007 and 2025, the Area is
projected to reduce SO2 emissions by 1,273 tpy,
NOX emissions by 9,224 tpy, PM2.5 emissions by
301 tpy, NH3 by 23 tpy, and VOC by 2,802 tpy. Thus, the
projected emissions inventories show that the Area will continue to
maintain the 1997 annual PM2.5 NAAQS during the 10 year
maintenance period.
3. Monitoring Network
EPA has determined that West Virginia's maintenance plan includes a
commitment to continue to operate its EPA-approved monitoring network,
as necessary to demonstrate ongoing compliance with the NAAQS. There
are two PM2.5 monitors in the Martinsburg Area. One is
located in West Virginia operated by the West Virginia Division of Air
Quality, and the other one is located in Maryland operated by the
Maryland Department of the Environment. In its August 5, 2013
submittal, West Virginia stated that it will consult with EPA prior to
making any necessary changes to the network and will continue to
quality assure the monitoring data in accordance with the requirements
of 40 CFR part 58.
4. Verification of Continued Attainment
To provide for tracking of the emission levels in the Area, WVDEP
requires major point sources to submit air emissions information
annually and prepares a new periodic inventory for all PM2.5
precursors every three years in accordance with EPA's Air Emissions
Reporting Requirements (AERR). EPA has determined that WVDEP will
continue to compare emissions information to the attainment year
inventory to assure continued attainment with the 1997 annual
PM2.5 NAAQS and that WVDEP will use this information to
assess emissions trends, as necessary.
5. Contingency Measures
The contingency plan provisions for maintenance plans are designed
to promptly correct a violation of the NAAQS that occurs after
redesignation. Section 175A of the CAA requires that a maintenance plan
include such contingency measures as EPA deems necessary to ensure that
a state will promptly correct a violation of the NAAQS that occurs
after redesignation. The maintenance plan should identify the events
that would ``trigger'' the adoption and implementation of a contingency
measure(s), the contingency measure(s) that would be adopted and
implemented, and the schedule indicating the time frame by which the
state would adopt and implement the measure(s).
West Virginia's maintenance plan outlines the procedures for the
adoption and implementation of contingency measures to further reduce
emissions should a violation occur. West Virginia's contingency
measures include a warning level response and an action
[[Page 25554]]
level response. An initial warning level response is triggered when the
average weighted annual mean for a single calendar year exceeds 15.5
[mu]g/m\3\ within the maintenance area. In that case, a study will be
conducted to determine if the emissions trends show increases; if
action is necessary to reverse emissions increases, West Virginia will
follow the same procedures for control selection and implementation as
for an action level response, and implementation of necessary controls
will take place as expeditiously as possible, but no later than 12
months from the end of the most recent calendar year.
The action level response will be prompted by any one of the
following: (1) A warning level response study that shows emissions
increases; (2) a weighted annual mean over a two-year average that
exceeds the standard; or (3) a violation of the standard in the
maintenance area. If an action level response is triggered, West
Virginia will adopt and implement appropriate control measures within
18 months from the end of the year in which monitored air quality
triggering a response occurs. West Virginia will also consider whether
additional regulations that are not a part of the maintenance plan can
be implemented in a timely manner to respond to the trigger.
West Virginia's candidate contingency measures include the
following: (1) Diesel reduction emission strategies; (2) alternative
fuels and diesel retrofit programs for fleet vehicle operations; (3)
PM2.5, SO2, and NOX emissions offsets
for new and modified major sources; (4) concrete manufacturing
controls; and (5) additional NOX reductions. Additionally,
West Virginia has identified a list of sources that could potentially
be controlled. These include: Industrial, commercial and institutional
(ICI) Boilers for SO2 and NOX controls, EGUs,
process heaters, internal combustion engines, combustion turbines,
other sources greater than 100 tpy, fleet vehicles, concrete
manufacturers, and aggregate processing plants. EPA finds that the West
Virginia maintenance plan for the Martinsburg Area includes appropriate
contingency measures as necessary to ensure West Virginia will promptly
correct any violation of the NAAQS that occurs after redesignation. For
all of the reasons discussed above, EPA is proposing to approve West
Virginia's 1997 annual PM2.5 maintenance plan for the
Martinsburg Area as meeting the requirements of section 175A of the
CAA.
C. Transportation Conformity
Section 176(c) of the CAA requires Federal actions in nonattainment
and maintenance areas to ``conform to'' the goals of SIPs. This means
that such actions will not cause or contribute to violations of a
NAAQS, worsen the severity of an existing violation, or delay timely
attainment of any NAAQS or any interim milestone. Actions involving
Federal Highway Administration (FHWA) or Federal Transit Administration
(FTA) funding or approval are subject to the transportation conformity
rule (40 CFR Part 93, subpart A). Under this rule, metropolitan
planning organizations (MPOs) in nonattainment and maintenance areas
coordinate with state air quality and transportation agencies, EPA, and
the FHWA and FTA to demonstrate that their long range transportation
plans and transportation improvement programs (TIP) conform to
applicable SIPs. This is typically determined by showing that estimated
emissions from existing and planned highway and transit systems are
less than or equal to the MVEBs contained in the SIP.
On August 5, 2013, West Virginia submitted a SIP revision that
contains the 2017 and 2025 PM2.5 and NOX onroad
mobile source budgets for the Martinsburg Area that comprises Berkeley
County, West Virginia. West Virginia did not provide emission budgets
for SO2, VOC, and NH3 because it concluded,
consistent with the presumptions regarding these precursors in the
Transportation Conformity Rule at 40 CFR 93.102(b)(2)(v), which
predated and was not disturbed by the litigation on the 1997
PM2.5 Implementation Rule, that emissions of these
precursors from motor vehicles are not significant contributors to the
Area's PM2.5 air quality problem. EPA issued conformity
regulations to implement the 1997 annual PM2.5 NAAQS in July
2004 and May 2005 (69 FR 40004, July 1, 2004 and 70 FR 24280, May 6,
2005). Those actions were not part of the final rule recently remanded
to EPA by the D.C. Circuit Court in NRDC v. EPA, No. 08-1250 (January
4, 2013), in which the D.C. Circuit Court remanded to EPA the 1997
PM2.5 Implementation Rule because it concluded that EPA must
implement that NAAQS pursuant to the PM-specific implementation
provisions of subpart 4, rather than solely under the general
provisions of subpart 1. That decision does not affect EPA's proposed
approval of the MVEBs for the Martinsburg Area. The MVEBs are presented
in Table 5.
Table 5--MVEBs for Berkeley County, West Virginia for the 1997 PM2.5
NAAQS in tpy
------------------------------------------------------------------------
Year PM2.5 NOX
------------------------------------------------------------------------
2017.......................................... 83 2,621
2015.......................................... 50 1,660
------------------------------------------------------------------------
EPA's substantive criteria for determining adequacy of MVEBs are
set out in 40 CFR 93.118(e)(4). Additionally, to approve the MVEBs, EPA
must complete a thorough review of the SIP, in this case the
PM2.5 maintenance plan, and conclude that with the projected
level of motor vehicle and all other emissions, the SIP will achieve
its overall purpose, in this case providing for maintenance of the 1997
annual PM2.5 NAAQS. EPA's process for determining adequacy
of a MVEB consists of three basic steps: (1) Providing public
notification of a SIP submission; (2) providing the public the
opportunity to comment on the MVEB during a public comment period; and
(3) EPA taking action on the MVEB.
On December 20, 2013, EPA initiated an adequacy review of the MVEBs
for the 1997 annual PM2.5 NAAQS that West Virginia included
in its redesignation request submittal. As such, a notice of the
submission of these MVEBs were posted on the adequacy Web site (https://www.epa.gov/otaq/stateresources/transconf/currsips.htm). The public
comment period closed on January 21, 2014. There were no public
comments received. EPA is acting on making the adequacy finding final
through a separate notice of adequacy. EPA has reviewed the MVEBs and
found them consistent with the maintenance plan and that the budgets
meet the criteria for adequacy and approval.
Therefore, EPA is proposing to approve the 2017 and 2025
PM2.5 and NOX MVEBs for Berkeley County for
transportation conformity purposes. Additional information pertaining
to the review of the MVEBs can be found in the TSD dated January 28,
2014, available on line at www.regulations.gov, Docket ID No. EPA-R03-
OAR-2013-0690.
VI. Proposed Actions
EPA is proposing to approve the redesignation of the West Virginia
portion of the Martinsburg Area from nonattainment to attainment for
the 1997 annual PM2.5 NAAQS. EPA has evaluated West
Virginia's redesignation request and determined that it meets the
redesignation criteria set forth in section 107(d)(3)(E) of the CAA.
EPA believes that the monitoring data demonstrate
[[Page 25555]]
that the Martinsburg Area has attained the 1997 annual PM2.5
NAAQS and will continue to attain the standard. Final approval of this
redesignation request would change the designation of the West Virginia
portion of the Martinsburg Area from nonattainment to attainment for
the 1997 PM2.5 annual NAAQS. EPA is also proposing to
approve the associated maintenance plan for the Area submitted on
August 5, 2013, as a revision to the West Virginia SIP because it meets
the requirements of section 175A of the CAA as described previously in
this rulemaking notice. In addition, EPA is proposing to approve the
2007 base year emissions inventory as meeting the requirement of
section 172(a)(3) of the CAA. Furthermore, EPA is proposing to approve
the 2017 and 2025 PM2.5 and NOX MVEBs submitted
by West Virginia for Berkeley County for transportation purposes. EPA
is soliciting public comments on the issues discussed in this document.
These comments will be considered before taking final action.
VII. 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 proposes to approve 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 Order
12866 (58 FR 51735, October 4, 1993);
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).
In addition, this rule proposing to approve West Virginia's
redesignation request, maintenance plan, 2007 base year emissions
inventory, and MVEBs for transportation conformity purposes for the
West Virginia portion of the Martinsburg Area for the 1997 annual
PM2.5 NAAQS, 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.
