ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52
[EPA-R03-OAR-2014-0910; FRL-9922-43-Region 3]
Approval and Promulgation of Air Quality Implementation Plans;
Pennsylvania; Infrastructure Requirements for the 2008 Ozone, 2010
Nitrogen Dioxide, 2010 Sulfur Dioxide, and 2012 Fine Particulate Matter
National Ambient Air Quality Standards
AGENCY: Environmental Protection Agency.
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve portions of four State Implementation Plan (SIP) revision
submittals from the Commonwealth of Pennsylvania pursuant to the Clean
Air Act (CAA). Whenever new or revised national ambient air quality
standards (NAAQS) are promulgated, the CAA requires states to submit a
plan for the implementation, maintenance, and enforcement of such
NAAQS. The plan is required to address basic program elements,
including, but not limited to, regulatory structure, monitoring,
modeling, legal authority, and adequate resources necessary to assure
attainment and maintenance of the standards. These elements are
referred to as infrastructure requirements. Pennsylvania has made four
separate submittals addressing the infrastructure requirements for the
2008 ozone, the 2010 nitrogen dioxide (NO2), the 2010 sulfur
dioxide (SO2), and the 2012 fine particulate matter
(PM2.5) NAAQS. In this rulemaking action, EPA is proposing
to approve, in accordance with the requirements of the CAA, the four
infrastructure SIP submissions with the exception of some portions of
the submittals addressing visibility protection.

SUPPLEMENTARY INFORMATION:
I. Background
On March 27, 2008 (73 FR 16436), EPA promulgated a revised NAAQS
for ozone based on 8-hour average concentrations. EPA revised the level
of the 8-hour ozone NAAQS from 0.08 parts per million (ppm) to 0.075
ppm. On February 9, 2010 (75 FR 6474), EPA established a new 1-hour
primary NAAQS for NO2 at a level of 100 parts per billion
(ppb), based on a 3-year average of the 98th percentile of the yearly
distribution of 1-hour daily maximum concentrations. On June 22, 2010
(75 FR 35520), EPA promulgated a revised NAAQS for SO2 at a
level of 75 ppb, based on a 3-year average of the annual 99th
percentile of 1-hour daily maximum concentrations. On December 14,
2012, EPA promulgated a revised primary NAAQS for PM2.5 for
the annual standard. The revised standard was set at the level of 12
micrograms per cubic meter (ug/m\3\) calculated as the annual average
which is averaged over a three year period. This specific NAAQS will be
referred to as the 2012 PM2.5 NAAQS.
Pursuant to section 110(a)(1) of the CAA, states are required to
submit SIPs meeting the applicable requirements of section 110(a)(2)
within three years after promulgation of a new or revised NAAQS or
within such shorter period as EPA may prescribe. Section 110(a)(2)
requires states to address basic SIP elements such as requirements for
monitoring, basic program requirements, and legal authority that are
designed to assure attainment and maintenance of the NAAQS. Section
110(a) imposes the obligation upon states to make a SIP submission to
EPA for a new or revised NAAQS, but the contents of that submission may
vary depending upon the facts and circumstances. In particular, the
data and analytical tools available at the time the state develops and
submits the SIP for a new or revised NAAQS affects the content of the
submission. The content of such SIP submission may also vary depending
upon what provisions the state's existing SIP already contains.
More specifically, section 110(a)(1) provides the procedural and
timing requirements for SIPs. Section 110(a)(2) lists specific elements
that states must meet for ``infrastructure'' SIP requirements related
to a newly
[[Page 6673]]
established or revised NAAQS. As mentioned earlier, these requirements
include basic SIP elements such as requirements for monitoring, basic
program requirements, and legal authority that are designed to assure
attainment and maintenance of the NAAQS.
II. Summary of State Submittals
The Commonwealth of Pennsylvania through the Pennsylvania
Department of Environmental Protection (PADEP) submitted four separate
revisions to its SIP to satisfy the requirements of section 110(a)(2)
of the CAA for the different NAAQS. On July 15, 2014, PADEP submitted
SIP revisions addressing the infrastructure requirements for the 2008
ozone, 2010 NO2, 2010 SO2 as well as the 2012
PM2.5 NAAQS. Each of the infrastructure SIP revisions
addressed the following infrastructure elements for the applicable
NAAQS which EPA is proposing to approve: Section 110(a)(2)(A), (B),
(C), (D)(i)(II) (prevention of significant deterioration(PSD)),
(D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M). The four
infrastructure SIP submittals do not address section
110(a)(2)(D)(i)(I), which pertains to interstate transport of
emissions, nor section 110(a)(2)(I), which pertains to the
nonattainment requirements of part D, Title I of the CAA, because this
element, section 110(a)(2)(I), is not required to be submitted by the 3
year submission deadline of CAA section 110(a)(1) and will be addressed
in a separate process, if necessary for the respective NAAQS. The
Pennsylvania infrastructure SIP submittals included provisions
addressing section 110(a)(2)(D)(i)(II) (visibility protection).
However, EPA is not taking action on the portion of the SIP submittals
addressing 110(a)(2)(D)(i)(II) (visibility protection) at this time and
will take later separate action on the portion of the infrastructure
SIP submittals addressing this element for the four NAAQS.
III. EPA's Approach To Review Infrastructure SIPs
EPA is acting upon the Commonwealth's SIP submissions that address
the infrastructure requirements of section 110(a)(1) and (2) of the CAA
for the 2008 ozone, the 2010 NO2, the 2010 SO2,
and the 2012 PM2.5 NAAQS. The requirement for states to make
a SIP submission of this type arises out of section 110(a)(1). Pursuant
to section 110(a)(1), states must make SIP submissions ``within 3 years
(or such shorter period as the Administrator may prescribe) after the
promulgation of a national primary ambient air quality standard (or any
revision thereof),'' and these SIP submissions are to provide for the
``implementation, maintenance, and enforcement'' of such NAAQS. The
statute directly imposes on states the duty to make these SIP
submissions, and the requirement to make the submissions is not
conditioned upon EPA's taking any action other than promulgating a new
or revised NAAQS. Section 110(a)(2) includes a list of specific
elements that ``[e]ach such plan'' submission must address.
EPA has historically referred to these SIP submissions made for the
purpose of satisfying the requirements of section 110(a)(1) and (2) as
``infrastructure SIP'' submissions. Although the term ``infrastructure
SIP'' does not appear in the CAA, EPA uses the term to distinguish this
particular type of SIP submission from submissions that are intended to
satisfy other SIP requirements under the CAA, such as ``nonattainment
SIP'' or ``attainment plan SIP'' submissions to address the
nonattainment planning requirements of part D of Title I of the CAA,
``regional haze SIP'' submissions required by EPA rule to address the
visibility protection requirements of section 169A of the CAA, and
nonattainment new source review permit program submissions to address
the permit requirements of CAA, Title I, part D.
Section 110(a)(1) addresses the timing and general requirements for
infrastructure SIP submissions and section 110(a)(2) provides more
details concerning the required contents of these submissions. The list
of required elements provided in section 110(a)(2) contains a wide
variety of disparate provisions, some of which pertain to required
legal authority, some of which pertain to required substantive program
provisions, and some of which pertain to requirements for both
authority and substantive program provisions.\1\ EPA therefore believes
that while the timing requirement in section 110(a)(1) is unambiguous,
some of the other statutory provisions are ambiguous. In particular,
EPA believes that the list of required elements for infrastructure SIP
submissions provided in section 110(a)(2) contains ambiguities
concerning what is required for inclusion in an infrastructure SIP
submission.
---------------------------------------------------------------------------
\1\ For example: Section 110(a)(2)(E)(i) provides that states
must provide assurances that they have adequate legal authority
under state and local law to carry out the SIP; Section 110(a)(2)(C)
provides that states must have a SIP-approved program to address
certain sources as required by part C of Title I of the CAA; and
section 110(a)(2)(G) provides that states must have legal authority
to address emergencies as well as contingency plans that are
triggered in the event of such emergencies.
---------------------------------------------------------------------------
The following examples of ambiguities illustrate the need for EPA
to interpret some section 110(a)(1) and section 110(a)(2) requirements
with respect to infrastructure SIP submissions for a given new or
revised NAAQS. One example of ambiguity is that section 110(a)(2)
requires that ``each'' SIP submission must meet the list of
requirements therein, while EPA has long noted that this literal
reading of the statute is internally inconsistent and would create a
conflict with the nonattainment provisions in part D of Title I of the
CAA, which specifically address nonattainment SIP requirements.\2\
Section 110(a)(2)(I) pertains to nonattainment SIP requirements and
part D addresses when attainment plan SIP submissions to address
nonattainment area requirements are due. For example, section 172(b)
requires EPA to establish a schedule for submission of such plans for
certain pollutants when the Administrator promulgates the designation
of an area as nonattainment, and section 107(d)(1)(B) allows up to two
years or in some cases three years, for such designations to be
promulgated.\3\ This ambiguity illustrates that rather than apply all
the stated requirements of section 110(a)(2) in a strict literal sense,
EPA must determine which provisions of section 110(a)(2) are applicable
for a particular infrastructure SIP submission.
---------------------------------------------------------------------------
\2\ See, e.g., ``Rule To Reduce Interstate Transport of Fine
Particulate Matter and Ozone (Clean Air Interstate Rule); Revisions
to Acid Rain Program; Revisions to the NOX SIP Call;
Final Rule,'' 70 FR 25162, at 25163-65 (May 12, 2005) (explaining
relationship between timing requirement of section 110(a)(2)(D)
versus section 110(a)(2)(I)).
\3\ EPA notes that this ambiguity within section 110(a)(2) is
heightened by the fact that various subparts of part D set specific
dates for submission of certain types of SIP submissions in
designated nonattainment areas for various pollutants. Note, e.g.,
that section 182(a)(1) provides specific dates for submission of
emissions inventories for the ozone NAAQS. Some of these specific
dates are necessarily later than three years after promulgation of
the new or revised NAAQS.
---------------------------------------------------------------------------
Another example of ambiguity within section 110(a)(1) and (2) with
respect to infrastructure SIPs pertains to whether states must meet all
of the infrastructure SIP requirements in a single SIP submission, and
whether EPA must act upon such SIP submission in a single action.
Although section 110(a)(1) directs states to submit ``a plan'' to meet
these requirements, EPA interprets the CAA to allow states to make
multiple SIP submissions separately addressing infrastructure SIP
elements for the same NAAQS. If states elect to make such multiple SIP
submissions to meet the
[[Page 6674]]
infrastructure SIP requirements, EPA can elect to act on such
submissions either individually or in a larger combined action.\4\
Similarly, EPA interprets the CAA to allow it to take action on the
individual parts of one larger, comprehensive infrastructure SIP
submission for a given NAAQS without concurrent action on the entire
submission. For example, EPA has sometimes elected to act at different
times on various elements and sub-elements of the same infrastructure
SIP submission.\5\
---------------------------------------------------------------------------
\4\ See, e.g., ``Approval and Promulgation of Implementation
Plans; New Mexico; Revisions to the New Source Review (NSR) State
Implementation Plan (SIP); Prevention of Significant Deterioration
(PSD) and Nonattainment New Source Review (NNSR) Permitting,'' 78 FR
4339 (January 22, 2013) (EPA's final action approving the structural
PSD elements of the New Mexico SIP submitted by the State separately
to meet the requirements of EPA's 2008 PM2.5 NSR rule),
and ``Approval and Promulgation of Air Quality Implementation Plans;
New Mexico; Infrastructure and Interstate Transport Requirements for
the 2006 PM2.5 NAAQS,'' 78 FR 4337 (January 22, 2013)
(EPA's final action on the infrastructure SIP for the 2006
PM2.5 NAAQS).
\5\ On December 14, 2007, the State of Tennessee, through the
Tennessee Department of Environment and Conservation, made a SIP
revision to EPA demonstrating that the State meets the requirements
of sections 110(a)(1) and (2). EPA proposed action for
infrastructure SIP elements (C) and (J) on January 23, 2012 (77 FR
3213) and took final action on March 14, 2012 (77 FR 14976). On
April 16, 2012 (77 FR 22533) and July 23, 2012 (77 FR 42997), EPA
took separate proposed and final actions on all other section
110(a)(2) infrastructure SIP elements of Tennessee's December 14,
2007 submittal.
---------------------------------------------------------------------------
Ambiguities within section 110(a)(1) and (2) may also arise with
respect to infrastructure SIP submission requirements for different
NAAQS. Thus, EPA notes that not every element of section 110(a)(2)
would be relevant, or as relevant, or relevant in the same way, for
each new or revised NAAQS. The states' attendant infrastructure SIP
submissions for each NAAQS therefore could be different. For example,
the monitoring requirements that a state might need to meet in its
infrastructure SIP submission for purposes of section 110(a)(2)(B)
could be very different for different pollutants, because the content
and scope of a state's infrastructure SIP submission to meet this
element might be very different for an entirely new NAAQS than for a
minor revision to an existing NAAQS.\6\
---------------------------------------------------------------------------
\6\ For example, implementation of the 1997 PM2.5
NAAQS required the deployment of a system of new monitors to measure
ambient levels of that new indicator species for the new NAAQS.
---------------------------------------------------------------------------
EPA notes that interpretation of section 110(a)(2) is also
necessary when EPA reviews other types of SIP submissions required
under the CAA. Therefore, as with infrastructure SIP submissions, EPA
also has to identify and interpret the relevant elements of section
110(a)(2) that logically apply to these other types of SIP submissions.
For example, section 172(c)(7) requires attainment plan SIP submissions
required by part D to meet the ``applicable requirements'' of section
110(a)(2); thus, attainment plan SIP submissions must meet the
requirements of section 110(a)(2)(A) regarding enforceable emission
limits and control measures and section 110(a)(2)(E)(i) regarding air
agency resources and authority. By contrast, it is clear that
attainment plan SIP submissions required by part D would not need to
meet the portion of section 110(a)(2)(C) that pertains to the PSD
program required in part C of Title I of the CAA, because PSD does not
apply to a pollutant for which an area is designated nonattainment and
thus subject to part D planning requirements. As this example
illustrates, each type of SIP submission may implicate some elements of
section 110(a)(2) but not others.
Given the potential for ambiguity in some of the statutory language
of section 110(a)(1) and section 110(a)(2), EPA believes that it is
appropriate to interpret the ambiguous portions of section 110(a)(1)
and section 110(a)(2) in the context of acting on a particular SIP
submission. In other words, EPA assumes that Congress could not have
intended that each and every SIP submission, regardless of the NAAQS in
question or the history of SIP development for the relevant pollutant,
would meet each of the requirements, or meet each of them in the same
way. Therefore, EPA has adopted an approach under which it reviews
infrastructure SIP submissions against the list of elements in section
110(a)(2), but only to the extent each element applies for that
particular NAAQS.
Historically, EPA has elected to use guidance documents to make
recommendations to states for infrastructure SIPs, in some cases
conveying needed interpretations on newly arising issues and in some
cases conveying interpretations that have already been developed and
applied to individual SIP submissions for particular elements.\7\ EPA
most recently issued guidance for infrastructure SIPs on September 13,
2013 (2013 Guidance).\8\ EPA developed this document to provide states
with up-to-date guidance for infrastructure SIPs for any new or revised
NAAQS. Within this guidance, EPA describes the duty of states to make
infrastructure SIP submissions to meet basic structural SIP
requirements within three years of promulgation of a new or revised
NAAQS. EPA also made recommendations about many specific subsections of
section 110(a)(2) that are relevant in the context of infrastructure
SIP submissions.\9\ The guidance also discusses the substantively
important issues that are germane to certain subsections of section
110(a)(2). EPA interprets section 110(a)(1) and (2) such that
infrastructure SIP submissions need to address certain issues and need
not address others. Accordingly, EPA reviews each infrastructure SIP
submission for compliance with the applicable statutory provisions of
section 110(a)(2), as appropriate.
---------------------------------------------------------------------------
\7\ EPA notes, however, that nothing in the CAA requires EPA to
provide guidance or to promulgate regulations for infrastructure SIP
submissions. The CAA directly applies to states and requires the
submission of infrastructure SIP submissions, regardless of whether
or not EPA provides guidance or regulations pertaining to such
submissions. EPA elects to issue such guidance in order to assist
states, as appropriate.
\8\ ``Guidance on Infrastructure State Implementation Plan (SIP)
Elements under Clean Air Act Sections 110(a)(1) and 110(a)(2),''
Memorandum from Stephen D. Page, September 13, 2013.
\9\ EPA's September 13, 2013, guidance did not make
recommendations with respect to infrastructure SIP submissions to
address Section 110(a)(2)(D)(i)(I). EPA issued the guidance shortly
after the U.S. Supreme Court agreed to review the DC Circuit
decision in EME Homer City, 696 F.3d 7 (D.C. Cir. 2012) which had
interpreted the requirements of section 110(a)(2)(D)(i)(I). In light
of the uncertainty created by ongoing litigation, EPA elected not to
provide additional guidance on the requirements of section
110(a)(2)(D)(i)(I) at that time. As the guidance is neither binding
nor required by statute, whether EPA elects to provide guidance on a
particular section has no impact on a state's CAA obligations.
---------------------------------------------------------------------------
As an example, section 110(a)(2)(E)(ii) is a required element of
section 110(a)(2) for infrastructure SIP submissions. Under this
element, a state must meet the substantive requirements of section 128,
which pertain to state boards that approve permits or enforcement
orders and heads of executive agencies with similar powers. Thus, EPA
reviews infrastructure SIP submissions to ensure that the state's SIP
appropriately addresses the requirements of section 110(a)(2)(E)(ii)
and section 128. The 2013 Guidance explains EPA's interpretation that
there may be a variety of ways by which states can appropriately
address these substantive statutory requirements, depending on the
structure of an individual state's permitting or enforcement program
(e.g., whether permits and enforcement orders are approved by a multi-
member board or by a head of an executive agency). However, they are
addressed by the state, the substantive requirements of
[[Page 6675]]
Section 128 are necessarily included in EPA's evaluation of
infrastructure SIP submissions because section 110(a)(2)(E)(ii)
explicitly requires that the state satisfy the provisions of section
128.
As another example, EPA's review of infrastructure SIP submissions
with respect to the PSD program requirements in section 110(a)(2)(C),
(D)(i)(II), and (J) focuses upon the structural PSD program
requirements contained in part C and EPA's PSD regulations. Structural
PSD program requirements include provisions necessary for the PSD
program to address all regulated sources and NSR pollutants, including
Green House Gases (GHGs). By contrast, structural PSD program
requirements do not include provisions that are not required under
EPA's regulations at 40 CFR 51.166 but are merely available as an
option for the state, such as the option to provide grandfathering of
complete permit applications with respect to the PM2.5
NAAQS. Accordingly, the latter optional provisions are types of
provisions EPA considers irrelevant in the context of an infrastructure
SIP action.
For other section 110(a)(2) elements, however, EPA's review of a
state's infrastructure SIP submission focuses on assuring that the
state's SIP meets basic structural requirements. For example, section
110(a)(2)(C) includes, inter alia, the requirement that states have a
program to regulate minor new sources. Thus, EPA evaluates whether the
state has an EPA-approved minor new source review program and whether
the program addresses the pollutants relevant to that NAAQS. In the
context of acting on an infrastructure SIP submission, however, EPA
does not think it is necessary to conduct a review of each and every
provision of a state's existing minor source program (i.e., already in
the existing SIP) for compliance with the requirements of the CAA and
EPA's regulations that pertain to such programs.
With respect to certain other issues, EPA does not believe that an
action on a state's infrastructure SIP submission is necessarily the
appropriate type of action in which to address possible deficiencies in
a state's existing SIP. These issues include: (i) Existing provisions
related to excess emissions from sources during periods of startup,
shutdown, or malfunction (SSM) that may be contrary to the CAA and
EPA's policies addressing such excess emissions; (ii) existing
provisions related to ``director's variance'' or ``director's
discretion'' that may be contrary to the CAA because they purport to
allow revisions to SIP-approved emissions limits while limiting public
process or not requiring further approval by EPA; and (iii) existing
provisions for PSD programs that may be inconsistent with current
requirements of EPA's ``Final NSR Improvement Rule,'' 67 FR 80186
(December 31, 2002), as amended by 72 FR 32526 (June 13, 2007) (NSR
Reform). Thus, EPA believes it may approve an infrastructure SIP
submission without scrutinizing the totality of the existing SIP for
such potentially deficient provisions and may approve the submission
even if it is aware of such existing provisions.\10\ It is important to
note that EPA's approval of a state's infrastructure SIP submission
should not be construed as explicit or implicit re-approval of any
existing potentially deficient provisions that relate to the three
specific issues just described.
---------------------------------------------------------------------------
\10\ By contrast, EPA notes that if a state were to include a
new provision in an infrastructure SIP submission that contained a
legal deficiency, such as a new exemption for excess emissions
during SSM events, then EPA would need to evaluate that provision
for compliance against the rubric of applicable CAA requirements in
the context of the action on the infrastructure SIP.
---------------------------------------------------------------------------
EPA's approach to review of infrastructure SIP submissions is to
identify the CAA requirements that are logically applicable to that
submission. EPA believes that this approach to the review of a
particular infrastructure SIP submission is appropriate, because it
would not be reasonable to read the general requirements of section
110(a)(1) and the list of elements in section 110(a)(2) as requiring
review of each and every provision of a state's existing SIP against
all requirements in the CAA and EPA regulations merely for purposes of
assuring that the state in question has the basic structural elements
for a functioning SIP for a new or revised NAAQS. Because SIPs have
grown by accretion over the decades as statutory and regulatory
requirements under the CAA have evolved, they may include some outmoded
provisions and historical artifacts. These provisions, while not fully
up to date, nevertheless may not pose a significant problem for the
purposes of ``implementation, maintenance, and enforcement'' of a new
or revised NAAQS when EPA evaluates adequacy of the infrastructure SIP
submission. EPA believes that a better approach is for states and EPA
to focus attention on those elements of section 110(a)(2) of the CAA
most likely to warrant a specific SIP revision due to the promulgation
of a new or revised NAAQS or other factors.
For example, EPA's 2013 Guidance gives simpler recommendations with
respect to carbon monoxide than other NAAQS pollutants to meet the
visibility requirements of section 110(a)(2)(D)(i)(II), because carbon
monoxide does not affect visibility. As a result, an infrastructure SIP
submission for any future new or revised NAAQS for carbon monoxide need
only state this fact in order to address the visibility prong of
section 110(a)(2)(D)(i)(II).
Finally, EPA believes that its approach with respect to
infrastructure SIP requirements is based on a reasonable reading of
section 110(a)(1) and (2) because the CAA provides other avenues and
mechanisms to address specific substantive deficiencies in existing
SIPs. These other statutory tools allow EPA to take appropriately
tailored action, depending upon the nature and severity of the alleged
SIP deficiency. Section 110(k)(5) authorizes EPA to issue a ``SIP
call'' whenever the Agency determines that a state's SIP is
substantially inadequate to attain or maintain the NAAQS, to mitigate
interstate transport, or to otherwise comply with the CAA.\11\ Section
110(k)(6) authorizes EPA to correct errors in past actions, such as
past approvals of SIP submissions.\12\ Significantly, EPA's
determination that an action on a state's infrastructure SIP submission
is not the appropriate time and place to address all potential existing
SIP deficiencies does not preclude EPA's subsequent reliance on
provisions in section 110(a)(2) as part of the basis for action to
correct those deficiencies at a later time. For example, although it
may not be appropriate to require a state to eliminate all existing
inappropriate director's discretion provisions in the course of acting
on an infrastructure SIP submission, EPA believes that section
110(a)(2)(A) may be
[[Page 6676]]
among the statutory bases that EPA relies upon in the course of
addressing such deficiency in a subsequent action.\13\
---------------------------------------------------------------------------
\11\ For example, EPA issued a SIP call to Utah to address
specific existing SIP deficiencies related to the treatment of
excess emissions during SSM events. See ``Finding of Substantial
Inadequacy of Implementation Plan; Call for Utah State
Implementation Plan Revisions,'' 74 FR 21639 (April 18, 2011).
\12\ EPA has used this authority to correct errors in past
actions on SIP submissions related to PSD programs. See ``Limitation
of Approval of Prevention of Significant Deterioration Provisions
Concerning Greenhouse Gas Emitting-Sources in State Implementation
Plans; Final Rule,'' 75 FR 82536 (December 30, 2010). EPA has
previously used its authority under section 110(k)(6) of the CAA to
remove numerous other SIP provisions that the Agency determined it
had approved in error. See, e.g., 61 FR 38664 (July 25, 1996) and 62
FR 34641 (June 27, 1997) (corrections to American Samoa, Arizona,
California, Hawaii, and Nevada SIPs); 69 FR 67062, November 16, 2004
(corrections to California SIP); and 74 FR 57051 (November 3, 2009)
(corrections to Arizona and Nevada SIPs).
\13\ See, e.g., EPA's disapproval of a SIP submission from
Colorado on the grounds that it would have included a director's
discretion provision inconsistent with CAA requirements, including
section 110(a)(2)(A). See, e.g., 75 FR 42342 at 42344 (July 21,
2010) (proposed disapproval of director's discretion provisions); 76
FR 4540 (January 26, 2011) (final disapproval of such provisions).

IV. Summary of EPA's Rationale for Proposing Approval
In this rulemaking action, EPA is proposing approval of the
Commonwealth's four infrastructure SIP submittals for the 2008 ozone,
2010 NO2, 2010 SO2, and 2012 PM2.5
NAAQS as addressing requirements in section 110(a)(2)(A), (B), (C),
(D)(i)(II) (prevention of significant deterioration), (D)(ii), (E),
(F), (G), (H), (J), (K), (L), and (M) of the CAA. A detailed analysis
of EPA's review and rationale for proposing to approve the four
infrastructure SIP submittals as addressing these CAA requirements may
be found in the Technical Support Document (TSD) for this proposed
rulemaking action which is available on line at www.regulations.gov,
Docket ID Number EPA-R03-OAR-2014-0910. EPA is not taking rulemaking
action at this time on the portion of the infrastructure SIP submittals
which address section 110(a)(2)(D)(i)(II) (visibility protection) for
the four NAAQS. EPA will take later rulemaking action on these
submittals regarding section 110(a)(2)(D)(i)(II) (visibility
protection).
EPA is soliciting public comments on the issues discussed in this
document. These comments will be considered before taking final action.
V. Proposed Action
EPA is proposing to approve the Commonwealth's infrastructure
submittals dated July 15, 2014 for the 2008 ozone, the 2010
NO2, the 2010 SO2, and the 2012 PM2.5
NAAQS respectively, as meeting the requirements of section 110(a)(2) of
the CAA, including specifically section 110(a)(2)(A), (B), (C),
(D)(i)(II) (prevention of significant deterioration), (D)(ii), (E),
(F), (G), (H), (J), (K), (L), and (M) for the four NAAQS with the
exception of the requirements related to section 110(a)(2)(D)(i)(II)
(visibility protection). The Commonwealth's infrastructure SIP
submissions for the four NAAQS did not include provisions addressing
CAA 110(a)(2)(D)(i)(I) and therefore EPA is not taking any action on
section 110(a)(2)(D)(i)(I) for any of the four NAAQS. The
Commonwealth's infrastructure SIP submissions for the four NAAQS also
did not include provisions addressing section 110(a)(2)(I) for any
nonattainment requirements of part D, Title I of the CAA, because this
element is not required to be submitted by the 3 year submission
deadline of CAA section 110(a)(1). EPA is also not taking action at
this time on the portions of the four infrastructure SIP submittals
intended to address section 110(a)(2)(D)(i)(II) (visibility
protection). EPA will take later separate action on the portion of the
infrastructure SIP submittals addressing CAA section
110(a)(2)(D)(i)(II) (visibility protection) for the four NAAQS.
VI. 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 proposed rulemaking action, pertaining to
Pennsylvania's section 110(a)(2) infrastructure requirements for the
2008 ozone, the 2010 NO2, the 2010 SO2, and 2012
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.
