Air Plan Approval; New Hampshire; Infrastructure Requirements for
the 2010 Sulfur Dioxide National Ambient Air Quality Standards
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is approving
elements of State Implementation Plan (SIP) submissions from New
Hampshire regarding the infrastructure requirements of the Clean Air
Act (CAA or Act) for the 2010 sulfur dioxide National Ambient Air
Quality Standards (NAAQS). EPA is also updating the classification for
two of New Hampshire's air quality control regions for sulfur dioxide
based on recent air quality monitoring data collected by the state.
Last, we are conditionally approving certain elements of New
Hampshire's submittal relating to prevention of significant
deterioration requirements.
The infrastructure requirements are designed to ensure that the
structural components of each state's air quality management program
are adequate to meet the state's responsibilities under the CAA.
DATES: This final rule is effective on August 8, 2016.

I. Summary of SIP Revision
On June 22, 2010 (75 FR 35520), EPA promulgated a revised NAAQS for
the 1-hour primary SO2 at a level of 75 parts per billion
(ppb), based on a 3-year average of the annual 99th percentile of 1-
hour daily maximum concentrations. 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.
On September 13, 2013, the New Hampshire Department of
Environmental Services (NH DES) submitted a SIP revision addressing
infrastructure elements specified in section 110(a)(2) of the CAA to
implement, maintain, and enforce the 2010 sulfur dioxide NAAQS. On July
17, 2015 (80 FR 42446), EPA published a notice of proposed rulemaking
(NPR) for the State of New Hampshire proposing approval of New
Hampshire's submittal. In the NPR, EPA proposed approval of the
following infrastructure elements: Section 110(a)(2)(A), (B), (C)
(enforcement and minor new source review), (D)(i)(II) (Visibility
Protection), (D)(ii) (International Pollution Abatement), (E)(i) and
(ii), (F), (G), (H), (J) (consultation, public notification, and
visibility protection), (K), (L), and (M), or portions thereof. EPA
also proposed to approve the PSD program relating to infrastructure
elements (C)(ii), D(i)(II), D(ii), and (J)(iii), except to
conditionally approve the aspect of the PSD program relating to
notification to neighboring states. Within the same NPR, EPA also
proposed taking similar action on New Hampshire's infrastructure SIP
submittals for the 2008 lead, 2008 ozone, and the 2010 nitrogen dioxide
standards. EPA has already finalized its action on the infrastructure
SIPs for the 2008 lead, 2008 ozone, and the 2010 nitrogen dioxide
standards (80 FR 78139, December 16, 2015).
In New Hampshire's September 13, 2013 infrastructure SIP for the
SO2 NAAQS, the state did not submit section 110(a)(2)(I)
which pertains to the
[[Page 44543]]
nonattainment requirements of part D, Title I of the CAA, since this
element is not required to be submitted by the 3-year submission
deadline of section 110(a)(1), and will be addressed in a separate
process. This rulemaking action also does not include action on section
110(a)(2)(D)(i)(I) of the CAA, because New Hampshire's September 13,
2013 infrastructure SIP submittal did not include provisions for this
element. EPA will take later, separate action on section
110(a)(2)(D)(i)(I) for the 2010 SO2 NAAQS for New Hampshire.
The rationale supporting EPA's proposed rulemaking action,
including the scope of infrastructure SIPs in general, is explained in
the published NPR. The NPR is available in the docket for this
rulemaking at www.regulations.gov, Docket ID Number EPA-R01-OAR-2012-
0950.
II. Public Comments and EPA's Responses
EPA received comments from the Sierra Club on the August 17, 2015
proposed rulemaking action on New Hampshire's 2010 SO2
infrastructure SIP. A full set of these comments is provided in the
docket for this final rulemaking action.
A. Sierra Club General Comments on Emission Limitations
1. The Plain Language of the CAA
Comment 1: Sierra Club (hereafter referred to as Commenter)
contends that the plain language of section 110(a)(2)(A) of the CAA,
legislative history of the CAA, case law, EPA regulations such as 40
CFR 51.112(a), and EPA interpretations in prior rulemakings require
that infrastructure SIPs include enforceable emission limits that
ensure attainment and maintenance of the NAAQS. Accordingly, Commenter
contends that any infrastructure SIP where emission limits are
inadequate to prevent exceedances of the NAAQS must be disapproved.
The Commenter states the main objective of the infrastructure SIP
process ``is to ensure that all areas of the country meet the NAAQS''
and states that nonattainment areas are addressed through
``nonattainment SIPs.'' The Commenter asserts the NAAQS ``are the
foundation upon which air emissions limitations and standards for the
entire country are set,'' including specific emission limitations for
most large stationary sources, such as coal-fired power plants. The
Commenter discusses the CAA's framework whereby states have primary
responsibility to assure air quality within the state, which the states
carry out through SIPs such as infrastructure SIPs required by section
110(a)(2). The Commenter also states that on its face the CAA requires
infrastructure SIPs ``to prevent exceedances of the NAAQS.'' In
support, the Commenter quotes the language in section 110(a)(1), which
requires states to adopt a plan for implementation, maintenance, and
enforcement of the NAAQS, and the language in section 110(a)(2)(A),
which requires SIPs to include enforceable emissions limitations as may
be necessary to meet the requirements of the CAA, which the Commenter
claims includes attainment and maintenance of the NAAQS. The Commenter
also notes the use of the word ``attain'' in section 110(a)(2)(H)(ii)
and suggests this is further evidence that the emission limits provided
for in section 110(a)(2)(A) must ensure attainment of the NAAQS.
Response 1: EPA disagrees that section 110 is clear on its face and
must be interpreted in the manner suggested by the Commenter. As we
have previously explained in response to the Commenter's similar
comments on EPA's actions approving other states' infrastructure SIPs,
section 110 is only one provision that is part of the complicated
structure governing implementation of the NAAQS program under the CAA,
as amended in 1990, and it must be interpreted in the context of not
only that structure, but also of the historical evolution of that
structure.\1\
---------------------------------------------------------------------------
\1\ See 80 FR 46494 (Aug. 5, 2015) (approving Pennsylvania
SO2 and ozone infrastructure SIP); 80 FR 11557 (Mar. 4,
2015) (approving Virginia SO2 infrastructure SIP); 79 FR
62022 (Oct. 16, 2014) (approving West Virginia SO2
infrastructure SIP); 79 FR 19001 (Apr. 7, 2014) (approving West
Virginia ozone infrastructure SIP); 79 FR 17043 (Mar. 27, 2014)
(approving Virginia ozone infrastructure SIP); and 80 FR 63436 (Oct.
20, 2015) (approving Minnesota ozone, NO2,
SO2, and PM2.5 infrastructure SIP).
---------------------------------------------------------------------------
EPA interprets infrastructure SIPs as more general planning SIPs,
consistent with the CAA as understood in light of its history and
structure. When Congress enacted the CAA in 1970, it did not include
provisions requiring states and the EPA to label areas as attainment or
nonattainment. Rather, states were required to include all areas of the
state in ``air quality control regions'' (AQCRs) and section 110 set
forth the core substantive planning provisions for these AQCRs. At that
time, Congress anticipated that states would be able to address air
pollution quickly pursuant to the very general planning provisions in
section 110 and could bring all areas into compliance with a new NAAQS
within five years. Moreover, at that time, section 110(a)(2)(A)(i)
specified that the section 110 plan provide for ``attainment'' of the
NAAQS and section 110(a)(2)(B) specified that the plan must include
``emission limitations, schedules, and timetables for compliance with
such limitations, and such other measures as may be necessary to insure
attainment and maintenance [of the NAAQS].''
In 1977, Congress recognized that the existing structure was not
sufficient and many areas were still violating the NAAQS. At that time,
Congress for the first time added provisions requiring states and EPA
to identify whether areas of a state were violating the NAAQS (i.e.,
were nonattainment) or were meeting the NAAQS (i.e., were attainment)
and established specific planning requirements in section 172 for areas
not meeting the NAAQS. In 1990, many areas still had air quality not
meeting the NAAQS and Congress again amended the CAA and added yet
another layer of more prescriptive planning requirements for each of
the NAAQS. At that same time, Congress modified section 110 to remove
references to the section 110 SIP providing for attainment, including
removing pre-existing section 110(a)(2)(A) in its entirety and
renumbering subparagraph (B) as section 110(a)(2)(A). Additionally,
Congress replaced the clause ``as may be necessary to insure attainment
and maintenance [of the NAAQS]'' with ``as may be necessary or
appropriate to meet the applicable requirements of this chapter.'' \2\
Thus, the CAA has significantly evolved in the more than 40 years since
it was originally enacted. While at one time section 110 of the CAA did
provide the only detailed SIP planning provisions for states and
specified that such plans must provide for attainment of the NAAQS,
under the structure of the current CAA, section 110 is only the initial
stepping-stone in the planning process for a specific NAAQS. More
detailed, later-enacted
[[Page 44544]]
provisions govern the substantive planning process, including planning
for attainment of the NAAQS.
---------------------------------------------------------------------------
\2\ The Commenter misses the mark by citing the word ``attain''
in CAA section 110(a)(2)(H) as evidence that the emission limits
submitted to satisfy the infrastructure requirements of 110(a)(2)(A)
must ensure attainment of the NAAQS. That portion of section
110(a)(2)(H) is referencing CAA section 110(k)(5)--the ``SIP call''
process--which allows the Administrator to make a finding of
substantial inadequacy with respect to a SIP. As discussed at
proposal, the existence of section 110(k)(5) bolster's the
reasonableness of EPA's approach to infrastructure SIP requirements,
which is based on a reasonable reading of sections 110(a)(1) and
110(a)(2). Section 110(k)(5) is one of the avenues and mechanisms
Congress provided to address specific substantive deficiencies in
existing SIPs. The SIP call process allows EPA to take appropriately
tailored action, depending upon the nature and severity of the
alleged SIP deficiency. Section 110(a)(2)(H)(ii) ensures that the
relevant state agency has the authority to revise the SIP in
response to a SIP call.
---------------------------------------------------------------------------
Thus, section 110 of the CAA is only one provision of the
complicated overall structure governing implementation of the NAAQS
program under the CAA, as amended in 1990, and must be interpreted in
the context of that structure and the historical evolution of that
structure. In light of the revisions to section 110 since 1970 and the
later promulgated and more specific planning requirements of the CAA,
EPA reasonably interprets the requirement in section 110(a)(2)(A) of
the CAA that the plan provide for ``implementation, maintenance and
enforcement'' to mean that the SIP must contain enforceable emission
limits that will aid in attaining and/or maintaining the NAAQS and that
the state demonstrate that it has the necessary tools to implement and
enforce a NAAQS, such as adequate state personnel and an enforcement
program. EPA has interpreted the requirement for emission limitations
in section 110 to mean that a state may rely on measures already in
place to address the pollutant at issue or any new control measures
that the state may choose to submit. Finally, as EPA has stated in the
2013 Guidance on Infrastructure State Implementation Plan (SIP)
Elements under Clean Air Act Sections 110(a)(1) and 110(a)(2) (``2013
Infrastructure SIP Guidance''), which specifically provides guidance to
states in addressing the 2010 SO2 NAAQS, ``[t]he conceptual
purpose of an infrastructure SIP submission is to assure that the air
agency's SIP contains the necessary structural requirements for the new
or revised NAAQS, whether by establishing that the SIP already contains
the necessary provisions, by making a substantive SIP revision to
update the SIP, or both.'' 2013 Infrastructure SIP Guidance at p. 1-
2.\3\
---------------------------------------------------------------------------
\3\ Thus, EPA disagrees with the Commenter's general assertion
that the main objective of infrastructure SIPs is to ensure all
areas of the country meet the NAAQS, as we believe the
infrastructure SIP process is the opportunity to review the
structural requirements of a state's air program. While the NAAQS
can be a foundation upon which emission limitations are set, as
explained in responses to subsequent comments, these emission
limitations are generally set in the attainment planning process
envisioned by part D of title I of the CAA, including, but not
limited to, CAA sections 172, 181-182, and 191-192.
---------------------------------------------------------------------------
2. The Legislative History of the CAA
Comment 2: The Commenter cites two excerpts from the legislative
history of the 1970 CAA, claiming they support an interpretation that
SIP revisions under CAA section 110 must include emissions limitations
sufficient to show maintenance of the NAAQS in all areas of the state.
The Commenter also contends that the legislative history of the CAA
supports the interpretation that infrastructure SIPs under section
110(a)(2) must include enforceable emission limitations, citing the
Senate Committee Report and the subsequent Senate Conference Report
accompanying the 1970 CAA.
Response 2: As provided in the previous response, the CAA, as
enacted in 1970, including its legislative history, cannot be
interpreted in isolation from the later amendments that refined that
structure and deleted relevant language from section 110 concerning
demonstrating attainment. See also 79 FR at 17046 (responding to
comments on Virginia's ozone infrastructure SIP). In any event, the two
excerpts of legislative history the Commenter cites merely provide that
states should include enforceable emission limits in their SIPs, and
they do not mention or otherwise address whether states are required to
include maintenance plans for all areas of the state as part of the
infrastructure SIP.
3. Case Law
Comment 3: The Commenter also discusses several cases applying the
CAA which the Commenter claims support its contention that courts have
been clear that section 110(a)(2)(A) requires enforceable emissions
limits in infrastructure SIPs to prevent exceedances of the NAAQS. The
Commenter first cites to language in Train v. Natural Resources Defense
Council, 421 U.S. 60, 78 (1975), addressing the requirement for
``emission limitations'' and stating that emission limitations ``are
the specific rules to which operators of pollution sources are subject,
and which if enforced should result in ambient air which meets the
national standards.'' The Commenter also cites Pennsylvania Department
of Environmental Resources v. EPA, 932 F.2d 269, 272 (3d Cir. 1991),
for the proposition that the CAA directs EPA to withhold approval of a
SIP where it does not ensure maintenance of the NAAQS, and to Mision
Industrial, Inc. v. EPA, 547 F.2d 123, 129 (1st Cir. 1976), which
quoted section 110(a)(2)(B) of the CAA of 1970. The Commenter contends
that the 1990 Amendments do not alter how courts have interpreted the
requirements of section 110, quoting Alaska Department of Environmental
Conservation v. EPA, 540 U.S. 461, 470 (2004), which in turn quoted
section 110(a)(2)(A) of the CAA and also stated that ``SIPs must
include certain measures Congress specified'' to ensure attainment of
the NAAQS. The Commenter also quotes several additional opinions in
this vein, including Montana Sulphur & Chemical Co. v. EPA, 666 F.3d
1174, 1180 (9th Cir. 2012) (``The Clean Air Act directs states to
develop implementation plans--SIPs--that `assure' attainment and
maintenance of national ambient air quality standards (`NAAQS') through
enforceable emission limitations.'') and Hall v. EPA, 273 F.3d 1146,
1161 (9th Cir. 2001) (EPA's analysis is required to ``reflect
consideration of the prospects of meeting current attainment
requirements under a revised air quality plan.''). Finally, the
Commenter cites Michigan Department of Environmental Quality v.
Browner, for the proposition that an infrastructure SIP must
``include[] emission limitations that result in compliance with the
NAAQS.'' 230 F.3d 181, 185 (6th Cir. 2000) (citing Train, 421 U.S. at
79).
Response 3: None of the cases the Commenter cites support its
contention that section 110(a)(2)(A) is clear that infrastructure SIPs
must include detailed plans providing for attainment and maintenance of
the NAAQS in all areas of the state, nor do they shed light on how
section 110(a)(2)(A) may reasonably be interpreted. With the exception
of Train, none of the cases the Commenter cites concerned the
interpretation of CAA section 110(a)(2)(A) (or section 110(a)(2)(B) of
the pre-1990 Act). Rather, the courts reference section 110(a)(2)(A)
(or section 110(a)(2)(B) of the pre-1990 CAA) in the background
sections of decisions in the context of a challenge to an EPA action on
revisions to a SIP that was required and approved or disapproved as
meeting other provisions of the CAA or in the context of an enforcement
action.
In Train, the Court was addressing a state revision to an
attainment plan submission made pursuant to section 110 of the CAA, the
sole statutory provision at that time regulating such submissions. The
issue in that case concerned whether changes to requirements that would
occur before attainment was required were variances that should be
addressed pursuant to the provision governing SIP revisions or were
``postponements'' that must be addressed under section 110(f) of the
CAA of 1970, which contained prescriptive criteria. The Court concluded
that EPA reasonably interpreted section 110(f) not to restrict a
state's choice of the mix of control measures needed to attain the
NAAQS and that revisions to SIPs that would not impact attainment of
the NAAQS by the attainment date were not subject to the limits of
section 110(f). Thus, the issue was not whether a section 110 SIP
[[Page 44545]]
needs to provide for attainment or whether emissions limits providing
such are needed as part of the SIP; rather the issue was which
statutory provision governed when the state wanted to revise the
emission limits in its SIP if such revision would not impact attainment
or maintenance of the NAAQS. To the extent the holding in the case has
any bearing on how section 110(a)(2)(A) might be interpreted, it is
important to realize that in 1975, when the opinion was issued, section
110(a)(2)(B) (the predecessor to section 110(a)(2)(A)) expressly
referenced the requirement to attain the NAAQS, a reference that was
removed in 1990.
The decision in Pennsylvania Department of Environmental Resources
was also decided based on the pre-1990 provision of the CAA. At issue
was whether EPA properly rejected a revision to an approved plan where
the inventories relied on by the state for the updated submission had
gaps. The Court quoted section 110(a)(2)(B) of the pre-1990 CAA in
support of EPA's disapproval, but did not provide any interpretation of
that provision. Yet, even if the Court had interpreted that provision,
EPA notes that it was modified by Congress in 1990; thus, this decision
has little bearing on the issue here.
At issue in Mision was the definition of ``emissions limitation,''
not whether section 110 requires the state to demonstrate how all areas
of the state will attain and maintain the NAAQS as part of their
infrastructure SIPs. The language from the opinion the Commenter quotes
does not interpret but rather merely describes section 110(a)(2)(A);
the decision in this case has no bearing here.\4\ In Montana Sulphur,
the Court was not reviewing an infrastructure SIP, but rather EPA's
disapproval of a SIP and promulgation of a federal implementation plan
(FIP) after a long history of the state failing to submit an adequate
SIP in response to EPA's finding under section 110(k)(5) that the
previously approved SIP was substantially inadequate to attain or
maintain the NAAQS. The Court cited generally to sections 107 and
110(a)(2)(A) of the CAA for the proposition that SIPs should assure
attainment and maintenance of NAAQS through emission limitations, but
this language was not part of the Court's holding in the case, which
focused instead on whether EPA's finding of SIP inadequacy, disapproval
of the state's required responsive attainment demonstration under
section 110(k)(5), and adoption of a remedial FIP under section 110(c)
were lawful. The Commenter suggests that Alaska Department of
Environmental Conservation stands for the proposition that the 1990 CAA
Amendments do not alter how courts interpret section 110. This claim is
inaccurate. Rather, the Court quoted section 110(a)(2)(A), which, as
noted previously, differs from the pre-1990 version of that provision
and the Court made no mention of the changed language. Furthermore, the
Commenter also quotes the Court's statement that ``SIPs must include
certain measures Congress specified,'' but that statement specifically
referenced the requirement in section 110(a)(2)(C), which requires an
enforcement program and a program for the regulation of the
modification and construction of new sources. Notably, at issue in that
case was the state's ``new source'' permitting program, not its
infrastructure SIP.
---------------------------------------------------------------------------
\4\ To the extent the comments could be read to include an
assertion that New Hampshire's SIP does not contain any ``emissions
limitations'' relevant to SO2, it should be noted that
state regulations at Env-A Chapter 400, Sulfur Content Limits in
Fuels, which EPA previously approved into the state's SIP, see 40
CFR 52.1520(c), are similar to the regulations that the Mision court
found to be an ``emission limitation'' in 1976. See 547 F.2d at 129.
---------------------------------------------------------------------------
Two of the other cases the Commenter cites, Michigan Department of
Environmental Quality and Hall, interpret CAA section 110(l), the
provision governing ``revisions'' to plans, and not the initial plan
submission requirement under section 110(a)(2) for a new or revised
NAAQS, such as the infrastructure SIP at issue in this instance. In
those cases, the courts cited to section 110(a)(2)(A) solely for the
purpose of providing a brief background of the CAA.
EPA does not believe any of these court decisions addressed
required measures for infrastructure SIPs and believes nothing in the
opinions addressed whether infrastructure SIPs need to contain measures
to ensure attainment and maintenance of the NAAQS.
4. EPA Regulations, Such as 40 CFR 51.112(a)
Comment 4: The Commenter cites to 40 CFR 51.112(a), providing that
each plan ``must demonstrate that the measures, rules and regulations
contained in it are adequate to provide for the timely attainment and
maintenance of the [NAAQS].'' The Commenter asserts that this
regulation requires infrastructure SIPs to include emissions limits
necessary to ensure attainment and maintenance of the NAAQS. The
Commenter states the provisions of 40 CFR 51.112 are not limited to
nonattainment SIPs and instead apply to infrastructure SIPs, which are
required to attain and maintain the NAAQS in all areas of a state. The
Commenter relies on a statement in the preamble to the 1986 action
restructuring and consolidating provisions in part 51, in which EPA
stated that ``[i]t is beyond the scope of th[is] rulemaking to address
the provisions of Part D of the Act . . .'' 51 FR 40656, 40656 (Nov. 7,
1986). The Commenter asserts 40 CFR 51.112(a) ``identifies the plans to
which it applies as those that implement the NAAQS,'' which it contends
means that Sec. 51.112(a) is applicable to infrastructure SIPs.
Response 4: The Commenter's reliance on 40 CFR 51.112 to support
its argument that infrastructure SIPs must contain emission limits
adequate to ensure attainment and maintenance of the NAAQS is not
supported. As an initial matter, EPA notes this regulatory provision
was initially promulgated and later restructured and consolidated prior
to the CAA Amendments of 1990, in which Congress removed all references
to ``attainment'' in section 110(a)(2)(A). And, it is clear on its face
that 40 CFR 51.112 applies to plans specifically designed to attain the
NAAQS. EPA interprets these provisions to apply when states are
developing ``control strategy'' SIPs such as the detailed attainment
and maintenance plans required under other provisions of the CAA, as
amended in 1977 and again in 1990, such as sections 175A, 181-182, and
191-192. The Commenter suggests that these provisions must apply to
section 110 SIPs because in the preamble to EPA's action
``restructuring and consolidating'' provisions in part 51, EPA stated
the new attainment demonstration provisions in the 1977 Amendments to
the CAA were ``beyond the scope'' of the rulemaking. It is important to
note, however, that EPA's action in 1986 was not to establish new
substantive planning requirements, but rather was meant merely to
consolidate and restructure provisions that had previously been
promulgated. EPA noted that it had already issued guidance addressing
the new ``Part D'' attainment planning obligations. Also, as to
maintenance regulations, EPA expressly stated that it was not making
any revisions other than to re-number those provisions. 51 FR at 40657.
Although EPA was explicit that it was not establishing requirements
interpreting the provisions of new ``Part D'' of the CAA, it is clear
the regulations being restructured and consolidated were intended to
address control strategy plans. In the preamble, EPA clearly stated
that 40 CFR 51.112 was
[[Page 44546]]
replacing 40 CFR 51.13 (``Control strategy: SOX and PM
(portion)''), 51.14 (``Control strategy: CO, HC, OX and
NO2 (portion)''), 51.80 (``Demonstration of attainment: Pb
(portion)''), and 51.82 (``Air quality data (portion)''). Id. at
40,660. Thus, the present-day 40 CFR 51.112 contains consolidated
provisions that are focused on control strategy SIPs, and the
infrastructure SIP is not such a plan.
5. EPA Interpretations in Other Rulemakings
Comment 5: The Commenter references a prior EPA rulemaking action
where EPA disapproved a SIP and claims that action shows EPA relied on
section 110(a)(2)(A) and 40 CFR 51.112 to reject the SIP. The Commenter
points to a 2006 partial approval and partial disapproval of revisions
to Missouri's existing control strategy plans addressing the
SO2 NAAQS. The Commenter claims EPA cited section
110(a)(2)(A) for disapproving a revision to the state plan on the basis
that the State failed to demonstrate the SIP was sufficient to ensure
maintenance of the SO2 NAAQS after revision of an emission
limit and claims EPA cited to 40 CFR 51.112 as requiring that a plan
demonstrates the rules in a SIP are adequate to attain the NAAQS. The
Commenter claims the revisions to Missouri's control strategy SIP for
SO2 were rejected by EPA because the revised control
strategy limits were also in Missouri's infrastructure SIP and thus the
weakened limits would have impacted the infrastructure SIP's ability to
aid in attaining and maintaining the NAAQS.
Response 5: EPA does not agree the prior Missouri rulemaking action
referenced by the Commenter establishes how EPA reviews infrastructure
SIPs. It is clear from the final Missouri rule that EPA was not
reviewing initial infrastructure SIP submissions under section 110 of
the CAA, but rather reviewing revisions that would make an already
approved SIP designed to demonstrate attainment of the NAAQS less
stringent. EPA's partial approval and partial disapproval of revisions
to restrictions on emissions of sulfur compounds for the Missouri SIP
in 71 FR 12623 addressed a control strategy SIP and not an
infrastructure SIP. Nothing in that action addresses the necessary
content of the initial infrastructure SIP for a new or revised NAAQS.
B. Sierra Club Comments on New Hampshire SIP SO2 Emission
Limits
The Commenter contends that the New Hampshire 2010 SO2
infrastructure SIP revisions did not revise the existing SO2
emission limits in response to the 2010 SO2 NAAQS and fail
to comport with assorted CAA requirements for SIPs to establish
enforceable emission limits that are adequate to prohibit NAAQS
exceedances in areas not designated nonattainment.
Comment 6: Citing section 110(a)(2)(A) of the CAA, the Commenter
contends that EPA may not approve New Hampshire's proposed 2010
SO2 infrastructure SIP, because it does not include
SO2 emissions limits or other required measures sufficient
to ensure attainment and maintenance of the SO2 NAAQS in
areas not designated nonattainment, which the Commenter claims is
required by section 110(a)(2)(A), and because it does not include
SO2 emission limits ``set in light of the 2010
SO2 NAAQS or even analyzed in light of the standard.'' The
Commenter also contended that section 110(a)(2)(A) requires not only
that the state air agency has the authority to adopt future emission
limitations, but that the SIP include existing substantive emission
limitations. The Commenter also provided results from a refined air
dispersion modeling analysis that evaluated SO2 impacts from
Schiller Station, which the commenter asserts demonstrate that
SO2 emission limits relied on in the infrastructure SIP are
insufficient to prevent exceedances of the NAAQS in both New Hampshire
and Maine and claims that emissions from this source can in theory, and
have in practice, resulted in exceedances of the 2010 SO2
NAAQS. Lastly, the commenter asserted the structure of the Act makes
clear that Congress did not intend states to be relieved of their
infrastructure SIP obligations under section 110(a)(2)(A) until
designations occur. For all of these reasons, the Commenter maintained
that EPA should disapprove New Hampshire's SO2
infrastructure SIP and promulgate a FIP.
Response 6: EPA disagrees with the Commenter that EPA must
disapprove New Hampshire's SO2 infrastructure SIP for the
reasons provided by the Commenter, including the Commenter's modeling
results and the state's allegedly insufficient SO2 emission
limits. EPA is not in this action making a determination regarding the
State's current air quality status or regarding whether its control
strategy is sufficient to attain and maintain the NAAQS. Therefore, EPA
is not in this action making any judgment on whether the Commenter's
submitted modeling demonstrates the NAAQS exceedances that the
Commenter claims. EPA believes that section 110(a)(2)(A) of the CAA is
reasonably interpreted to require states to submit infrastructure SIPs
that reflect the first step in their planning for attainment and
maintenance of a new or revised NAAQS. These SIP revisions should
contain a demonstration the state has the available tools and authority
to develop and implement plans to attain and maintain the NAAQS and
show that the SIP has enforceable control measures. In light of the
structure of the CAA, EPA's longstanding position regarding
infrastructure SIPs is that they are general planning SIPs to ensure
that the state has adequate resources and authority to implement a
NAAQS in general throughout the state and not detailed attainment and
maintenance plans for each individual area of the state. As mentioned
above, EPA has interpreted this to mean with regard to the requirement
for emission limitations that states may rely on measures already in
place to address the pollutant at issue or any new control measures
that the state may choose to submit. As stated in response to a
previous more general comment, section 110 of the CAA is only one
provision that is part of the complicated structure governing
implementation of the NAAQS program under the CAA, as amended in 1990,
and it must be interpreted in the context of not only that structure,
but also of the historical evolution of that structure. In light of the
revisions to section 110 since 1970 and the later-promulgated and more
specific planning requirements of the CAA, EPA reasonably interprets
the requirement in section 110(a)(2)(A) of the CAA that the plan
provide for ``implementation, maintenance and enforcement'' to mean
that the SIP must contain enforceable emission limits that will aid in
attaining and/or maintaining the NAAQS and that the State demonstrate
that it has the necessary tools to implement and enforce a NAAQS, such
as adequate state personnel and an enforcement program. As discussed
above, EPA has interpreted the requirement for emission limitations in
section 110 to mean the state may rely on measures already in place to
address the pollutant at issue or any new control measures that the
state may choose to submit. Finally, as EPA stated in the 2013
Infrastructure SIP Guidance, which specifically provides guidance to
states in addressing the 2010 SO2 NAAQS, ``[t]he conceptual
purpose of an infrastructure SIP submission is to assure that the air
agency's SIP contains the necessary structural requirements for the new
or revised NAAQS, whether by establishing that the SIP already contains
the necessary provisions, by
[[Page 44547]]
making a substantive SIP revision to update the SIP, or both.'' 2013
Infrastructure SIP Guidance at p. 2. On April 12, 2012, EPA explained
its expectations regarding implementation of the 2010 SO2
NAAQS via letters to each of the states. EPA communicated in the April
2012 letters that all states were expected to submit SIPs meeting the
``infrastructure'' SIP requirements under section 110(a)(2) of the CAA
by June 2013. At the time, EPA was undertaking a stakeholder outreach
process to continue to develop possible approaches for determining
attainment status under the SO2 NAAQS and implementing this
NAAQS. EPA made abundantly clear in the April 2012 letters that EPA did
not expect states to submit substantive attainment demonstrations or
modeling demonstrations showing attainment for areas not designated
nonattainment in infrastructure SIPs due in June 2013. Although EPA had
previously suggested in its 2010 SO2 NAAQS preamble and in
prior draft implementation guidance in 2011 that states should, in the
unique SO2 context, use the section 110(a) SIP process as
the vehicle for demonstrating attainment of the NAAQS, this approach
was never adopted as a binding requirement and was subsequently
discarded in the April 2012 letters to states. The April 2012 letters
recommended states focus infrastructure SIPs due in June 2013, such as
New Hampshire's SO2 infrastructure SIP, on traditional
``infrastructure elements'' in section 110(a)(1) and (2) rather than on
modeling demonstrations for future attainment for areas not designated
as nonattainment.\5\ Therefore, EPA asserts that evaluations of
modeling demonstrations such as the one submitted by the Commenter are
more appropriately considered in actions that make determinations
regarding states' current air quality status or regarding future air
quality status. EPA also asserts that SIP revisions for SO2
nonattainment areas, including measures and modeling demonstrating
attainment, are due by the dates statutorily prescribed under subpart 5
under part D. Those submissions are due no later than 18 months after
an area is designated nonattainment for SO2, under CAA
section 191(a). Thus, the CAA directs states to submit these SIP
requirements that are specific for nonattainment areas on a separate
schedule from the ``structural requirements'' of 110(a)(2) which are
due within three years of adoption or revision of a NAAQS and which
apply statewide. The infrastructure SIP submission requirement does not
move up the date for any required submission of a part D plan for areas
designated nonattainment for the new NAAQS. Thus, elements relating to
demonstrating attainment for areas not attaining the NAAQS are not
necessary for infrastructure SIP submissions,\6\ and the CAA does not
provide explicit requirements for demonstrating attainment for areas
that have not yet been designated regarding attainment with a
particular NAAQS. As stated previously, EPA believes that the proper
inquiry at this juncture is whether New Hampshire has met the basic
structural SIP requirements appropriate at the point in time EPA is
acting upon the infrastructure submittal. Emissions limitations and
other control measures needed to attain the NAAQS in areas designated
nonattainment for that NAAQS are due on a different schedule from the
section 110 infrastructure elements. A state, like New Hampshire, may
reference preexisting SIP emission limits or other rules contained in
part D plans for previous NAAQS in an infrastructure SIP submission.
New Hampshire's existing rules and emission reduction measures in the
SIP that control emissions of SO2 were discussed in the
state's submittal.\7\ These provisions have the ability to reduce
SO2 overall. Although the New Hampshire SIP relies on
measures and programs used to implement previous SO2 NAAQS,
these provisions are not limited to reducing SO2 levels to
meet one specific NAAQS and will continue to provide benefits for the
2010 SO2 NAAQS. Additionally, as discussed in the NPR, New
Hampshire has the ability to revise its SIP when necessary (e.g. in the
event the Administrator finds the plan to be substantially inadequate
to attain the NAAQS or otherwise meet all applicable CAA requirements)
as required under element H of section 110(a)(2).
---------------------------------------------------------------------------
\5\ In EPA's final SO2 NAAQS preamble, 75 FR 35520
(June 22, 2010), and subsequent draft guidance in March and
September 2011, EPA had expressed its expectation that many areas
would be initially designated as unclassifiable due to limitations
in the scope of the ambient monitoring network and the short time
available before which states could conduct modeling to support
their designations recommendations due in June 2011. In order to
address concerns about potential violations in these unclassifiable
areas, EPA initially recommended that states submit substantive
attainment demonstration SIPs based on air quality modeling by June
2013 (under section 110(a)) that show how their unclassifiable areas
would attain and maintain the NAAQS in the future. Implementation of
the 2010 Primary 1-Hour SO2 NAAQS, Draft White Paper for
Discussion, May 2012 (``2012 Draft White Paper'') (for discussion
purposes with Stakeholders at meetings in May and June 2012),
available at http://www.epa.gov/airquality/sulfurdioxide/implement.html. However, EPA clearly stated in this 2012 Draft White
Paper its clarified implementation position that it was no longer
recommending such attainment demonstrations for unclassifiable areas
for June 2013 infrastructure SIPs. Id. EPA had stated in the
preamble to the NAAQS and in the prior 2011 draft guidance that EPA
intended to develop and seek public comment on guidance for modeling
and development of SIPs for sections 110 and 191 of the CAA. Section
191 of the CAA requires states to submit SIPs in accordance with
section 172 for areas designated nonattainment with the
SO2 NAAQS. After seeking such comment, EPA has now issued
guidance for the nonattainment area SIPs due pursuant to sections
191 and 172. See Guidance for 1-Hour SO2 Nonattainment Area SIP
Submissions, Stephen D. Page, Director, EPA's Office of Air Quality
Planning and Standards, to Regional Air Division Directors Regions
1-10, April 23, 2014. In September 2013, EPA had previously issued
specific guidance relevant to infrastructure SIP submissions due for
the NAAQS, including the 2010 SO2 NAAQS. See 2013
Infrastructure SIP Guidance.
\6\ For this reason, EPA disagrees with the comment that the
infrastructure SIP process is the appropriate mechanism in which to
demonstrate that emission limitations for Merrimack Station are
sufficient to ensure the Central New Hampshire nonattainment area
attains the standard.
\7\ New Hampshire cites to several SIP approved emission
limitations relevant to SO2 to demonstrate compliance
with section 110(a)(2)(A), including Chapter Env-A 400 (Sulfur
Content Limits in Fuels)(renumbered Env-A 1600). Thus, to the extent
the Commenter meant to suggest that New Hampshire only has authority
to set future emission limitations, but that the SIP contains none
relevant to the 2010 SO2 NAAQS, we disagree.
---------------------------------------------------------------------------
The requirements for emission reduction measures for an area
designated nonattainment for the 2010 primary SO2 NAAQS are
in sections 172 and 191-192 of the CAA, and therefore, the appropriate
avenue for implementing requirements for necessary emission limitations
for demonstrating attainment with the 2010 SO2 NAAQS is
through the attainment planning process contemplated by those sections
of the CAA. On August 5, 2013, EPA designated as nonattainment most
areas in locations where existing monitoring data from 2009-2011
indicated violations of the 1-hour SO2 standard. 78 FR
47191. At that time, one area in New Hampshire had monitoring data from
2009-2011 indicating violations of the 1-hour SO2 standard,
and this area was designated nonattainment in New Hampshire. See 40 CFR
81.330. On March 2, 2015 the United States District Court for the
Northern District of California entered a Consent Decree among the EPA,
Sierra Club and Natural Resources Defense Council to resolve litigation
concerning the deadline for completing designations for the 2010
SO2 NAAQS. Pursuant to the terms of the Consent Decree, EPA
will complete additional designations for all remaining areas of the
country including remaining areas in New Hampshire.\8\
---------------------------------------------------------------------------
\8\ The Consent Decree, entered March 2, 2015 by the United
States District Court for the Northern District of California in
Sierra Club and NRDC v. EPA, Case 3:13-cv-03953-SI (N.D. Cal.) is
available at http://www3.epa.gov/so2designations/pdfs/201503FinalCourtOrder.pdf.
---------------------------------------------------------------------------
[[Page 44548]]
For the area designated nonattainment in New Hampshire in August
2013, the attainment SIP was due by April 4, 2015 and must contain a
demonstration that the area will attain the 2010 SO2 NAAQS
as expeditiously as practicable, but no later than October 4, 2018
pursuant to sections 172, 191 and 192 of the CAA, including a plan for
enforceable measures to reach attainment of the NAAQS. Similar
attainment planning SIPs for any additional areas which EPA
subsequently designates nonattainment with the 2010 SO2
NAAQS will be due for such areas within the timeframes specified in CAA
section 191. EPA believes it is not appropriate to interpret the
overall section 110(a)(2) infrastructure SIP obligation to require
bypassing the attainment planning process by imposing separate
requirements outside the attainment planning process. Such actions
would be disruptive and premature absent exceptional circumstances and
would interfere with a state's planning process. See In the Matter of
EME Homer City Generation LP and First Energy Generation Corp., Order
on Petitions Numbers III-2012-06, III-2012-07, and III 2013-01 (July
30, 2014) (hereafter, Homer City/Mansfield Order) at 10-19 (finding
Pennsylvania SIP did not require imposition of 1-hour SO2
emission limits on sources independent of the part D attainment
planning process contemplated by the CAA). The history of the CAA and
intent of Congress for the CAA as described above demonstrate clearly
that it is within the section 172 and general part D attainment
planning process that New Hampshire must include SO2
emission limits on sources, where needed, for the area designated
nonattainment to reach attainment with the 2010 1-hour SO2
NAAQS and for any additional areas EPA may subsequently designate
nonattainment. EPA agrees that the structure of the Act makes clear
that Congress did not intend to postpone a state's obligation to submit
and infrastructure SIP under section 110(a)(2)(A) until designations
occur. EPA disagrees, however, with the Commenter's interpretation that
section 110(a)(2)(A) requires a state to submit SO2 emission
limitations for individual sources during this infrastructure SIP
planning process that ensure attainment and maintenance of the 2010
SO2 NAAQS. As stated above, in light of the revisions to
section 110 since 1970 and the later-promulgated and more specific
planning requirements of the CAA, EPA reasonably interprets the
requirement in section 110(a)(2)(A) that the plan provide for
``implementation, maintenance and enforcement'' to mean that the SIP
must contain enforceable emission limits that will aid in attaining
and/or maintaining the NAAQS and that the State demonstrate that it has
the necessary tools to implement and enforce a NAAQS.
As noted in EPA's preamble for the 2010 SO2 NAAQS,
determining compliance with the SO2 NAAQS will likely be a
source-driven analysis and EPA has explored options to ensure that the
SO2 designations process realistically accounts for
anticipated SO2 reductions at sources that we expect will be
achieved by current and pending national and regional rules. See 75 FR
35520 (June 22, 2010). As mentioned previously, EPA will act in
accordance with the entered Consent Decree's schedule for conducting
additional designations for the 2010 SO2 NAAQS and any areas
designated nonattainment must meet the applicable part D requirements
for these areas. However, because the purpose of an infrastructure SIP
submission is for more general planning purposes, EPA does not believe
New Hampshire was obligated during this infrastructure SIP planning
process to account for controlled SO2 levels at individual
sources to satisfy section 110(a)(2)(A). See Homer City/Mansfield Order
at 10-19. Regarding the air dispersion modeling conducted by the
Commenter pursuant to AERMOD for Schiller Station, EPA does not find
the modeling information relevant at this time for review of an
infrastructure SIP. While EPA has extensively discussed the use of
modeling for attainment demonstration purposes and for designations,
EPA has affirmatively stated such modeling was not needed to
demonstrate attainment for the SO2 infrastructure SIPs under
the 2010 SO2 NAAQS. See April 12, 2012 letters to states
regarding SO2 implementation and Implementation of the 2010
Primary 1-Hour SO2 NAAQS, Draft White Paper for Discussion,
May 2012, available at http://www.epa.gov/airquality/sulfurdioxide/implement.html.\9\ EPA's Data Requirements Rule contains a process by
which state air agencies characterize air quality around SO2
sources through ambient monitoring and/or air quality modeling
techniques and submit such data to the EPA. See, e.g., 80 FR 51502
(Aug. 21, 2015). The rule includes a discussion of how EPA anticipates
addressing modeling that informs determinations of states' air quality
status under the 2010 SO2 NAAQS. As stated above, EPA
believes it is not appropriate to bypass the attainment planning
process by imposing separate attainment planning process requirements
outside part D and into the infrastructure SIP process.

---------------------------------------------------------------------------
In conclusion, EPA disagrees with the Commenter's statements that
EPA must disapprove New Hampshire's infrastructure SIP submission
because it does not establish specific enforceable SO2
emission limits, either on coal-fired EGUs or other large
SO2 sources, in order to demonstrate attainment and
maintenance with the NAAQS at this time.\10\ Because we are approving
New Hampshire's infrastructure SIP submission with respect to section
110(a)(2)(A), we need not promulgate a federal implementation plan. See
CAA section 110(c)(1).
---------------------------------------------------------------------------
\10\ Finally, EPA does not disagree with the Commenter's claim
that coal-fired EGUs are a large source of SO2 emissions
in New Hampshire based on the 2011 NEI. However, EPA does not agree
that this information is relevant to our approval of the
infrastructure SIP, which EPA has explained meets requirements in
CAA section 110(a)(2).
---------------------------------------------------------------------------
Comment 7: The Commenter claims that New Hampshire's proposed
SO2 infrastructure SIP lacks emission limitations for
Schiller Station informed by air dispersion modeling as well as other
large SO2 sources outside of the nonattainment area and
therefore fails to ensure New Hampshire will attain and maintain the
2010 SO2 NAAQS. The Commenter claims EPA must disapprove the
SO2 infrastructure SIP as it does not ``prevent
exceedances'' or ensure attainment and maintenance of the
SO2 NAAQS.
Response 7: EPA agrees with the Commenter that air dispersion
modeling, such as AERMOD, can be an important tool in the CAA section
107 designations process for SO2 and in developing SIPs for
nonattainment areas as required by sections 172 and 191-192, including
supporting required attainment demonstrations. EPA agrees that prior
EPA statements, EPA guidance, and case law support the use of air
dispersion modeling in the SO2 designations process and
attainment demonstration process, as well as in analyses of the
interstate impact of transported emissions and whether existing
approved SIPs remain adequate
[[Page 44549]]
to show attainment and maintenance of the SO2 NAAQS.
However, as provided in the previous responses, EPA disagrees with the
Commenter that EPA must disapprove the New Hampshire SO2
infrastructure SIP for its alleged failure to include source-specific
SO2 emission limits that show no exceedances of the NAAQS
when modeled or ensure attainment and maintenance of the NAAQS.
In acting to approve or disapprove an infrastructure SIP, EPA is
not required to make findings regarding current air quality status of
areas within the state, such area's projected future air quality
status, or whether existing emissions limits in such area are
sufficient to meet a NAAQS in the area. The attainment planning process
detailed in part D of the CAA, including sections 172 and 191-192
attainment SIPs, is the appropriate place for the state to evaluate
measures needed to bring in-state nonattainment areas into attainment
with a NAAQS and to impose additional emission limitations such as
SO2 emission limits on specific sources.
EPA had initially recommended that states submit substantive
attainment demonstration SIPs based on air quality modeling in the
final 2010 SO2 NAAQS preamble, 75 FR 35520 (June 22, 2010),
and in subsequent draft guidance issued in September 2011 for the
section 110(a) SIPs due in June 2013 in order to show how areas then-
expected to be designated as unclassifiable would attain and maintain
the NAAQS. These initial statements in the preamble and 2011 draft
guidance, presented only in the context of the new 1-hour
SO2 NAAQS and not suggested as a matter of general
infrastructure SIP policy, were based on EPA's expectation at the time
that, by June 2012, most areas would initially be designated as
unclassifiable due to limitations in the scope of the ambient
monitoring network and the short time available before which states
could conduct modeling to support designations recommendations in 2011.
However, after conducting extensive stakeholder outreach and receiving
comments from the states regarding these initial statements and the
timeline for implementing the NAAQS, EPA subsequently stated in the
April 12, 2012 letters and in the 2012 Draft White Paper that EPA was
clarifying its 2010 SO2 NAAQS implementation position and
was no longer recommending such attainment demonstrations supported by
air dispersion modeling for unclassifiable areas (which had not yet
been designated) for the June 2013 infrastructure SIPs. Instead, EPA
explained that it expected states to submit infrastructure SIPs that
followed the general policy EPA had applied under other NAAQS. EPA then
reaffirmed this position in the February 6, 2013 memorandum, ``Next
Steps for Area Designations and Implementation of the Sulfur Dioxide
National Ambient Air Quality Standard.'' \11\ As previously mentioned,
EPA had stated in the preamble to the NAAQS and in the prior 2011 draft
guidance that EPA intended to develop and seek public comment on
guidance for modeling and development of SIPs for sections 110, 172 and
191- 192 of the CAA. After receiving such further comment, EPA has now
issued guidance for the nonattainment area SIPs due pursuant to
sections 172 and 191-192. See April 23, 2014 Guidance for 1-Hour
SO2 Nonattainment Area SIP Submissions. In addition,
modeling may be an appropriate consideration for states and EPA in
further designations for the SO2 NAAQS in accordance with
the Sierra Club and NRDC Consent Decree and the data requirements rule
mentioned previously.\12\ While the EPA guidance for attainment SIPs
and for designations for CAA section 107 and the process for
characterizing SO2 emissions from larger sources discuss the
use of air dispersion modeling, EPA's 2013 Infrastructure SIP Guidance
did not suggest that states use air dispersion modeling for purposes of
the section 110(a)(2) infrastructure SIP. Therefore, as discussed
previously, EPA believes the New Hampshire SO2
infrastructure SIP submittal contains the structural requirements to
address elements in section 110(a)(2) as discussed in the proposed
approval. EPA believes infrastructure SIPs are general planning SIPs to
ensure that a state has adequate resources and authority to implement a
NAAQS. Infrastructure SIP submissions are not intended to act or
fulfill the obligations of a detailed attainment and/or maintenance
plan for each individual area of the state that is not attaining the
NAAQS. While infrastructure SIPs must address modeling authorities in
general for section 110(a)(2)(K), EPA believes 110(a)(2)(K) requires
infrastructure SIPs to provide the state's authority for air quality
modeling and for submission of modeling data to EPA, not specific air
dispersion modeling for large stationary sources of pollutants. In the
proposal for this rulemaking action, EPA provided an explanation of New
Hampshire's ability and authority to conduct air quality modeling when
required and its authority to submit modeling data to the EPA. The
comments relating to EPA's use of AERMOD or modeling in general in
designations pursuant to section 107 are likewise irrelevant as EPA's
present approval of New Hampshire's infrastructure SIP is unrelated to
the section 107 designations process. As outlined in the August 23,
2010 clarification memo, ``Applicability of Appendix W Modeling
Guidance for the 1-hour SO2 National Ambient Air Quality
Standard'' (U.S. EPA, 2010a), AERMOD is the preferred model for single
source modeling to address the 1-hour SO2 NAAQS as part of
the NSR/PSD permit programs. Therefore, as attainment SIPs,
designations, and NSR/PSD actions are outside the scope of a required
infrastructure SIP for the 2010 SO2 NAAQS for section
110(a), EPA provides no further response to the Commenter's discussion
of air dispersion modeling for these applications. If the Commenter
resubmits its air dispersion modeling for the New Hampshire EGU, or
updated modeling information in the appropriate context, EPA will
address the resubmitted modeling or updated modeling at that time.

---------------------------------------------------------------------------
The Commenter, citing administrative law principles regarding
consideration of comments provided during a rulemaking process,\13\
contends that EPA must consider the modeling data the Commenter has
submitted ``over the years which demonstrate the inadequacy of New
Hampshire's rules.'' For the reasons previously explained, however, the
purpose for which the Commenter submitted the modeling--namely, to
assert that current air quality in the area in which Schiller Station
is located does not meet the NAAQS--is not relevant to EPA's action on
this infrastructure SIP, and consequently EPA is not required to
consider the modeling in evaluating the approvability of the
infrastructure SIP.
[[Page 44550]]
EPA does not believe infrastructure SIPs must contain emission
limitations informed by air dispersion modeling in order to meet the
requirements of section 110(a)(2)(A). Thus, EPA has evaluated the
persuasiveness of the Commenter's submitted modeling in finding that it
is not relevant to the approvability of New Hampshire's proposed
infrastructure SIP for the 2010 SO2 NAAQS, but EPA has made
no judgment regarding whether the Commenter's submitted modeling is
sufficient to show violations of the NAAQS.
---------------------------------------------------------------------------
\13\ The Commenter cites to Motor Vehicle Manufacturers
Association v. State Farm Mutual Auto Insurance Co., 463 U.S. 29, 43
(1983) and NRDC v. EPA, 571 F.3d 1245, 1254 (D.C. Cir. 2009).
---------------------------------------------------------------------------
While EPA does not believe that infrastructure SIP submissions are
required to contain emission limits assuring in-state attainment of the
NAAQS, as suggested by the Commenter, EPA does recognize that in the
past, states have, in their discretion, used infrastructure SIP
submittals as a `vehicle' for incorporating regulatory revisions or
source-specific emission limits into the state's plan. See 78 FR 73442
(December 6, 2013) (approving regulations Maryland submitted for
incorporation into the SIP along with the 2008 ozone infrastructure SIP
to address ethics requirements for State Boards in sections 128 and
110(a)(2)(E)(ii)). While these SIP revisions are intended to help the
state meet the requirements of section 110(a)(2), these ``ride-along''
SIP revisions are not intended to signify that all infrastructure SIP
submittals must, in order to be approved by EPA, have similar
regulatory revisions or source-specific emission limits. Rather, the
regulatory provisions and source-specific emission limits the state
relies on when showing compliance with section 110(a)(2) have, in many
cases, likely already been incorporated into the state's SIP prior to
each new infrastructure SIP submission; in some cases this was done for
entirely separate CAA requirements, such as attainment plans required
under section 172, or for previous NAAQS.
Comment 8: The Commenter asserts that EPA may not approve the
proposed New Hampshire SO2 infrastructure SIP because it
fails to include enforceable emission limitations with a 1-hour
averaging time (or, if longer averaging periods are used, more
stringent numerical emission limits) that apply at all times. For
support, the Commenter cites to the definition of ``emission
limitation'' at CAA section 302(k). The Commenter also claims EPA has
stated that 1-hour averaging times are necessary for the 2010
SO2 NAAQS citing to EPA's April 23, 2014 Guidance for 1-Hour
SO2 Nonattainment Area SIP Submissions, a February 3, 2011,
EPA Region 7 letter to the Kansas Department of Health and Environment
regarding the need for 1-hour SO2 emission limits in a PSD
permit, an EPA Environmental Appeals Board (EAB) decision rejecting use
of a 3-hour averaging time for a SO2 limit in a PSD
permit,\14\ and EPA's disapproval of a Missouri SIP that relied on
annual averaging for SO2 emission rates.\15\ Thus, the
Commenter contends EPA must disapprove New Hampshire's infrastructure
SIP, which the Commenter claims fails to require emission limits with
adequate averaging times.
---------------------------------------------------------------------------
\14\ In re Mississippi Lime Co., 15 E.A.D. 349, 379-82 (EAB Aug.
9, 2011).
\15\ 71 FR 12623, 12,624 (Mar. 13, 2006) (disapproving a control
strategy SO2 SIP).
---------------------------------------------------------------------------
Response 8: EPA disagrees that EPA must disapprove the proposed New
Hampshire infrastructure SIP because the SIP does not contain
enforceable SO2 emission limitations with 1-hour averaging
periods that apply at all times, as this issue is not appropriate for
resolution at this stage. The comment does not assert that the
SO2 emission limits in New Hampshire's SIP are not
enforceable or that they do not apply at all times, instead the comment
focuses on the lack of 1-hour averaging times. As EPA has noted
previously, the purpose of the section 110(a)(2) SIP is to ensure that
the State has the necessary structural components to implement programs
for attainment and maintenance of the NAAQS.\16\
---------------------------------------------------------------------------
\16\ As EPA has stated, some areas are designated nonattainment
areas pursuant to CAA section 107 for the 2010 SO2 NAAQS
in the State. Thus, while the State, at this time, has an obligation
to submit attainment plans for the 2010 SO2 NAAQS for
sections 172, 191 and 192, EPA believes the appropriate time for
examining necessity of the averaging periods within any submitted
SO2 emission limits on specific sources is within the
attainment planning process.
---------------------------------------------------------------------------
While EPA does agree that the averaging time is a critical
consideration for purposes of substantive SIP revisions, such as
attainment demonstrations, the averaging time of existing rules in the
SIP is not relevant for determining that the State has met the
applicable requirements of section 110(a)(2) with respect to the
infrastructure elements addressed in the present SIP action.\17\
Therefore, because EPA finds New Hampshire's SO2
infrastructure SIP approvable without the additional SO2
emission limitations showing in-state attainment of the NAAQS, EPA
finds the issues of appropriate averaging periods for such future
limitations not relevant at this time. The Commenter has cited to prior
EPA discussion on emission limitations required in PSD permits (from an
EAB decision and EPA's letter to Kansas' permitting authority) pursuant
to part C of the CAA, which is neither relevant nor applicable to the
present SIP action. In addition, as previously discussed, the EPA
disapproval of the 2006 Missouri SIP was a disapproval relating to a
control strategy SIP required pursuant to part D attainment planning
and is likewise not relevant to the analysis of infrastructure SIP
requirements.
---------------------------------------------------------------------------
\17\ For a discussion on emission averaging times for emissions
limitations for SO2 attainment SIPs, see the April 23,
2014 Guidance for 1-Hour SO2 Nonattainment Area SIP
Submissions. EPA explained that it is possible, in specific cases,
for states to develop control strategies that account for
variability in 1-hour emissions rates through emission limits with
averaging times that are longer than 1-hour, using averaging times
as long as 30- days, but still provide for attainment of the 2010
SO2 NAAQS as long as the limits are of at least
comparable stringency to a 1-hour limit at the critical emission
value. EPA has not yet evaluated any specific submission of such a
limit, and so is not at this time prepared to take final action to
implement.
---------------------------------------------------------------------------
Comment 9: The Commenter states that enforceable emission limits in
SIPs are necessary to avoid additional nonattainment designations in
areas where modeling or monitoring shows SO2 levels exceed
the 1-hour SO2 NAAQS and cites to a February 6, 2013 EPA
document, Next Steps for Area Designations and Implementation of the
Sulfur Dioxide National Ambient Air Quality Standard, which the
Commenter contends discusses how states could avoid future
nonattainment designations. The Commenter claims the modeling it
conducted for Schiller Station indicates exceedances over a wide area
in both New Hampshire and Maine. The Commenter states that additional
areas in New Hampshire will have to be designated nonattainment ``if
source-specific enforceable emissions limits are not placed on PSNH
Schiller Station through this I-SIP.'' In summary, the Commenter
asserts that, ``in order to implement the NAAQS, comply with section
110(a)(2)(A), and avoid additional nonattainment designations for areas
impacted by'' Schiller Station, EPA must disapprove the New Hampshire
infrastructure SIP and ensure that emission limits ``relied upon in the
Infrastructure SIP'' will not allow large sources of SO2 to
cause exceedances of the 2010 SO2 NAAQS.
Response 9: EPA appreciates the Commenter's concern with avoiding
nonattainment designations in New Hampshire for the 2010 SO2
NAAQS. However, Congress designed the CAA such that states have the
primary responsibility for achieving and maintaining the NAAQS within
their geographic areas by submitting SIPs
[[Page 44551]]
which will specify the details of how the states will meet the NAAQS.
Pursuant to section 107(d), the states make initial recommendations of
designations for areas within each state and EPA then promulgates the
designations after considering the state's submission and other
information. EPA promulgated initial designations for the 2010
SO2 NAAQS in August 2013 for areas in which monitoring at
that time showed violations of the NAAQS, but has not yet issued
designations for other areas and will complete the required
designations pursuant to the schedule contained in the recently entered
Consent Decree. EPA will designate additional areas for the 2010
SO2 NAAQS in accordance with CAA section 107 and existing
EPA policy and guidance. New Hampshire may, on its own accord, decide
to impose additional SO2 emission limitations to avoid
future designations to nonattainment. If additional New Hampshire areas
are designated nonattainment, New Hampshire will then have the initial
opportunity to develop additional emissions limitations needed to
attain the NAAQS, and EPA would be charged with reviewing whether the
SIP is adequate to demonstrate attainment. See Commonwealth of Virginia
v. EPA, 108 F.3d 1397, 1410 (D.C. Cir. 1997) (citing Nat. Res. Def.
Council, Inc. v. Browner, 57 F.3d 1122, 1123 (D.C. Cir. 1995))
(discussing that states have primary responsibility for determining an
emission reductions program for its areas subject to EPA approval
dependent upon whether the SIP as a whole meets applicable requirements
of the CAA). However, such considerations are not required of New
Hampshire at the infrastructure SIP stage of NAAQS implementation, as
the Commenter's statements concern the separate designations process
under section 107.\18\ EPA disagrees that the infrastructure SIP must
be disapproved for not including enforceable emissions limitations to
prevent future 1-hour SO2 nonattainment designations.
---------------------------------------------------------------------------
\18\ EPA also notes that in EPA's final rule regarding the 2010
SO2 NAAQS, EPA noted that it anticipates several
forthcoming national and regional rules, such as the Industrial
Boilers standard under CAA section 112, are likely to require
significant reductions in SO2 emissions over the next
several years. See 75 FR 35520. EPA continues to believe similar
national and regional rules will lead to SO2 reductions
that will help achieve compliance with the 2010 SO2
NAAQS. If it appears that states with areas designated nonattainment
in 2013 will nevertheless fail to attain the NAAQS as expeditiously
as practicable (but no later than October 2018) during EPA's review
of attainment SIPs required by section 172, the CAA provides
authorities and tools for EPA to solve such failure, including, as
appropriate, disapproving submitted SIPs and promulgating federal
implementation plans. Likewise, for any areas designated
nonattainment after 2013, EPA has the same authorities and tools
available to address any areas which do not timely attain the NAAQS.
---------------------------------------------------------------------------
Comment 10: The commenter notes that New Hampshire did not include
a submittal to satisfy CAA section 110(a)(2)(D)(i)(I) (the so-called
``Good Neighbor'' provision) and asserts that, as a result, ``EPA must
take immediate action here to disapprove the SO2 I-SIP
Certification . . . and initiate the FIP [Federal Implementation Plan]
process with regard to the I-SIP's `Good Neighbor' provisions.''
Response 10: EPA is not taking any action at this time with respect
to Element D(i)(I), which addresses emissions that significantly
contribute to nonattainment or interfere with maintenance of the NAAQS
in another state, also known as ``good neighbor'' SIPs or ``interstate
transport'' SIPs. As the commenter notes, New Hampshire did not include
any provisions to address the requirements of section
110(a)(2)(D)(i)(I) in its September 13, 2013infrastructure SIP
submittal for the 2010 SO2 NAAQS. In the NPR, EPA did not
propose to take any action with respect to New Hampshire's obligations
pursuant to section 110(a)(2)(D)(i)(I) for the September 13, 2013
infrastructure SIP submittal.
Because New Hampshire did not make a submission in its September
13, 2013 SIP submittal to address the requirements of section
110(a)(2)(D)(i)(I), EPA is not required to have proposed or to take
final SIP approval or disapproval action on this element under section
110(k) of the CAA. In this case, there has been no substantive
submission for EPA to evaluate under section 110(k). Nor does the lack
of a submission addressing section 110(a)(2)(D)(i)(I) require EPA to
disapprove New Hampshire's September 13, 2013 SIP submittal as to the
other elements of section 110(a)(2). EPA interprets its authority under
section 110(k)(3) of the CAA as affording EPA the discretion to
approve, or conditionally approve, individual elements of New
Hampshire's infrastructure SIP submissions, separate and apart from any
action with respect to the requirements of section 110(a)(2)(D)(i)(I)
of the CAA. EPA views discrete infrastructure SIP requirements in
section 110(a)(2), such as the requirements of 110(a)(2)(D)(i)(I), as
severable from the other infrastructure elements and interprets section
110(k)(3) as allowing it to act on individual severable measures in a
plan submission.
On August 21, 2012, the D.C. Circuit issued a decision in EME Homer
City Generation, L.P. v. EPA, 696 F.3d 7, 31 (D.C. Cir. 2012), holding,
among other things, that states had no obligation to submit good
neighbor SIPs until the EPA had first quantified each state's good
neighbor obligation. Accordingly, under that decision the submission
deadline for good neighbor SIPs under the CAA would not necessarily be
tied to the promulgation of a new or revised NAAQS. While the EPA
sought review first with the D.C. Circuit en banc and then with the
United States Supreme Court, the EPA complied with the D.C. Circuit's
ruling during the pendency of its appeal. The D.C. Circuit declined to
consider EPA's appeal en banc, but, on April 29, 2014, the Supreme
Court reversed the D.C. Circuit's EME Homer City opinion and held,
among other things, that under the plain language of the CAA, states
must submit SIPs addressing the good neighbor requirement in CAA
section 110(a)(2)(D)(i)(I) within three years of promulgation of a new
or revised NAAQS, regardless of whether the EPA first provides
guidance, technical data or rulemaking to quantify the state's
obligation.
Pursuant to CAA section 110(c)(1), EPA is authorized and obligated
to promulgate a FIP, if EPA takes any of the following actions: (1)
Finds that a state has failed to make a required SIP submission; (2)
finds that a required submission was incomplete; or (3) disapproves a
required SIP submission in whole or in part. With respect to the 2010
SO2 NAAQS, EPA has not issued a finding of failure to
submit, issued a finding of incompleteness, or disapproved the
submission in whole or in part. Consequently, the two-year FIP clock
has not yet begun to run. EPA agrees in general that sections 110(a)(1)
and (a)(2) of the CAA require states to submit, within three years of
promulgation of a new or revised NAAQS, a plan that addresses cross-
state air pollution under section 110(a)(2)(D)(i)(I). In this
rulemaking, however, EPA is only approving portions of New Hampshire's
infrastructure SIP submissions for the 2010 SO2 NAAQS, which
did not include provisions for interstate transport under section
110(a)(2)(D)(i)(I). A finding of failure to submit a SIP submission for
the 2010 SO2 NAAQS addressing section 110(a)(2)(D)(i)(I)
could occur in a separate rulemaking. As that issue was not addressed
in the July 17, 2015 NPR,\19\ and is thus not pertinent to this
[[Page 44552]]
rulemaking, EPA provides no further response. In sum, New Hampshire's
and EPA's obligations regarding interstate transport of pollution for
the 2010 SO2 NAAQS will be addressed in later rulemakings.
---------------------------------------------------------------------------
\19\ See 80 FR 42446, 42452 (July 17, 2015) (``In today's
rulemaking, EPA is not proposing to approve or disapprove New
Hampshire's compliance with section 110(a)(2)(D)(i)(I) with respect
to the 2008 ozone, 2010 NO2 and 2010 SO2
NAAQS, since New Hampshire's infrastructure SIPs for these NAAQS do
not include a submittal with respect to transport for sub-element 1,
prongs 1 and 2.'').
---------------------------------------------------------------------------
III. Final Action
EPA is approving a SIP submission from New Hampshire certifying the
state's current SIP is sufficient to meet the required infrastructure
elements under sections 110(a)(1) and (2) for the 2010 SO2
NAAQS, with the exception of certain aspects relating to the state's
PSD program which we are conditionally approving. On September 25,
2015, we conditionally approved the portion of New Hampshire's PSD
program that pertains to providing notification to neighboring states
of certain permitting actions in New Hampshire. See 80 FR 57722.
Therefore, we are conditionally approving herein the related portions
of New Hampshire's infrastructure SIP submittals affected by our
September 25, 2015 conditional approval. A summary of EPA's actions
regarding these infrastructure SIP requirements are contained in Table
1 below.

------------------------------------------------------------------------
In the above table, the key is as follows:
A--Approve
A*--Approve, but conditionally approve aspect of PSD program relating
to notification to neighboring states
+--Not germane to infrastructure SIPs
NS--No Submittal
NA--Not applicable
Additionally, we are updating the classification of two air quality
control regions in New Hampshire at 40 CFR 52.1521. The classification
of the Androscoggin Valley Interstate control region is being revised
from Priority 1A to Priority III and the Merrimack Valley--Southern New
Hampshire Interstate control region is being revised from Priority I to
Priority III based on recent air quality monitoring data collected by
the state.
EPA is conditionally approving an aspect of New Hampshire's SIP
revision submittals pertaining to the state's PSD program. The
outstanding issue with the PSD program concerns the lack of a
requirement that neighboring states be notified of the issuance of a
PSD permit by the New Hampshire Department of Environmental Services.
On September 25, 2015, we conditionally approved New Hampshire's PSD
program for this reason. See 80 FR 57722. Accordingly, we are also
conditionally approving this aspect of New Hampshire's infrastructure
SIP revisions for the 2010 SO2 NAAQS. New Hampshire must
submit to EPA a SIP submittal addressing the above mentioned deficiency
in the state's PSD program within the timeframe provided within our
September 25, 2015 action. If the State fails to do so, the elements we
are conditionally approving in this rulemaking will be disapproved on
that date. EPA will notify the State by letter that this action has
occurred. At that time, this commitment will no longer be a part of the
approved New Hampshire SIP. EPA subsequently will publish a document in
the Federal Register notifying the public that the conditional approval
automatically converted to a disapproval. If the State meets its
commitment within the applicable time frame, the conditionally approved
submission will remain a part of the SIP until EPA takes final action
approving or disapproving the new submittal. If EPA disapproves the new
submittal, the conditionally approved aspect of New Hampshire's PSD
program will also be disapproved at that time. If EPA approves the
revised PSD program submittal, then the portions of New Hampshire's
infrastructure SIP submittals that were conditionally approved will be
fully approved in their entirety and replace the conditional approval
in the SIP. In addition, final disapproval of an infrastructure SIP
submittal triggers the Federal implementation plan (FIP) requirement
under section 110(c).
[[Page 44553]]
IV. Statutory and Executive Order Reviews
Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this action merely approves state law as meeting Federal
requirements and does not impose additional requirements beyond those
imposed by state law. For that reason, this action:
Is not a significant regulatory action subject to review
by the Office of Management and Budget under Executive Orders 12866 (58
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the Clean Air Act; 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, the SIP is not approved to apply on any Indian
reservation land or in any other area where EPA or an Indian tribe has
demonstrated that a tribe has jurisdiction. In those areas of Indian
country, the rule does not have tribal implications and will not impose
substantial direct costs on tribal governments or preempt tribal law as
specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this action and
other required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. A major rule cannot
take effect until 60 days after it is published in the Federal
Register. This action is not a ``major rule'' as defined by 5 U.S.C.
804(2).
Under section 307(b)(1) of the Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by September 6, 2016. Filing a
petition for reconsideration by the Administrator of this final rule
does not affect the finality of this action for the purposes of
judicial review nor does it extend the time within which a petition for
judicial review may be filed, and shall not postpone the effectiveness
of such rule or action. This action may not be challenged later in
proceedings to enforce its requirements. (See section 307(b)(2)).
