Air Plan Approval; Indiana; Regional Haze Plan and Prong 4
(Visibility) for the 2006 and 2012 PM2.5, 2010 NO2, 2010 SO2, and 2008
Ozone NAAQS
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to take
action under the Clean Air Act (CAA) on an Indiana's November 27, 2017
State Implementation Plan (SIP) submittal addressing regional haze.
This proposed action is based on EPA's determination that a state's
implementation of the Cross-State Air Pollution Rule (CSAPR) program
continues to meet the criteria of the Regional Haze Rule (RHR) to
qualify as an alternative to the application of Best Available Retrofit
Technology (BART). EPA is proposing several related actions. First, EPA
is proposing to approve the portion of Indiana's
[[Page 23505]]
November 27, 2017 SIP submittal seeking to change reliance from the
Clean Air Interstate Rule (CAIR) to CSAPR for certain regional haze
requirements. EPA is also proposing to convert EPA's limited approval/
limited disapproval of Indiana's regional haze SIP to a full approval
and to withdraw the Federal Implementation Plan (FIP) provisions that
address the limited disapproval. Finally, EPA is proposing to approve
the visibility prong of Indiana's infrastructure SIP submittals for the
2012 annual and 2006 24-hour fine particulate matter
(PM2.5), 2010 nitrogen dioxide (NO2), and 2010
sulfur dioxide (SO2) National Ambient Air Quality Standards
(NAAQS) and to convert EPA's disapproval of the visibility portion of
Indiana's infrastructure SIP submittal for the 2008 ozone NAAQS to an
approval.

I. Background
A. Regional Haze SIPs and Their Relationship With CAIR and CSAPR
Section 169A(a)(1) of the CAA establishes as a national visibility
goal ``the prevention of any future, and the remedying of any existing,
impairment of visibility in mandatory class I Federal areas which
impairment results from manmade air pollution.'' Section 169A(b)(2)(A)
of the CAA requires states to submit regional haze SIPs that contain
such measures as may be necessary to make reasonable progress towards
the natural visibility goal, including a requirement that certain
categories of existing major stationary sources built between 1962 and
1977 procure, install, and operate BART as determined by the state.
Under the RHR, states are directed to conduct BART determinations for
such ``BART-eligible'' sources that may be anticipated to cause or
contribute to any visibility impairment in a Class I area. Rather than
requiring source-specific BART controls, states also have the
flexibility to adopt an emissions trading program or other alternative
program as long as the alternative provides greater reasonable progress
towards improving visibility than BART. See 40 CFR 51.308(e)(2). EPA
provided states with this flexibility in the RHR, adopted in 1999, and
further refined the criteria for assessing whether an alternative
program provides for greater reasonable progress in two subsequent
rulemakings. See 64 FR 35714 (July 1, 1999); 70 FR 39104 (July 6,
2005); 71 FR 60612 (October 13, 2006).
In revisions to the regional haze program made in 2005, EPA
demonstrated that CAIR would achieve greater reasonable progress than
BART.\1\ See 70 FR 39104. In those revisions, EPA amended its
regulations to provide that states participating in the CAIR cap-and-
trade programs pursuant to an EPA-approved CAIR SIP, or states that
remain subject to a CAIR FIP need not require affected BART-eligible
electric generating units (EGUs) to install, operate, and maintain BART
for emissions of SO2 and nitrogen oxides (NOX).
---------------------------------------------------------------------------
\1\ CAIR created regional cap-and-trade programs to reduce
SO2 and NOX emissions in 27 eastern states
(and the District of Columbia), including Indiana, that contributed
to downwind nonattainment or interfered with maintenance of the 1997
8-hour ozone NAAQS or the 1997 PM2.5 NAAQS.
---------------------------------------------------------------------------
As a result of EPA's determination that CAIR was ``better-than-
BART,'' a number of states in which CAIR applies, including Indiana,
relied on the CAIR cap-and-trade programs as an alternative to BART for
EGU emissions of SO2 and NOX in designing their
regional haze SIPs. These states also relied on CAIR as an element of a
long-term strategy (LTS) for achieving reasonable progress goals (RPGs)
for their regional haze programs. However, in 2008, the United States
Court of Appeals for the District of Columbia Circuit (D.C. Circuit)
remanded CAIR to EPA without vacatur (preserving the environmental
benefits provided by CAIR). North Carolina v. EPA, 550 F.3d 1176, 1178
(D.C. Cir. 2008). On August 8, 2011 (76 FR 48208), acting on the D.C.
Circuit's remand, EPA promulgated CSAPR to replace CAIR and issued FIPs
to implement the rule in CSAPR-subject states.\2\ Implementation of
CSAPR was scheduled to begin on January 1, 2012, when CSAPR would have
superseded the CAIR program.
---------------------------------------------------------------------------
\2\ CSAPR requires 28 eastern states to limit their statewide
emissions of SO2 and/or NOX in order to
mitigate transported air pollution unlawfully impacting other
states' ability to attain or maintain four NAAQS: The 1997 ozone
NAAQS, the 1997 annual PM2.5 NAAQS, the 2006 24-hour
PM2.5 NAAQS, and the 2008 8-hour ozone NAAQS. The CSAPR
emissions limitations are defined in terms of maximum statewide
``budgets'' for emissions of annual SO2, annual
NOX, and/or ozone-season NOX by each covered
state's large EGUs. The CSAPR state budgets are implemented in two
phases of generally increasing stringency, with the Phase 1 budgets
applying to emissions in 2015 and 2016 and the Phase 2 budgets
applying to emissions in 2017 and later years.
---------------------------------------------------------------------------
Due to the D.C. Circuit's 2008 ruling that CAIR was ``fatally
flawed,'' and its resulting status as a temporary measure following
that ruling, EPA could not fully approve regional haze SIPs to the
extent that they relied on CAIR to satisfy the BART requirement and the
requirement for a LTS sufficient to achieve the state-adopted RPGs. On
these grounds, EPA finalized a limited disapproval of Indiana's
regional haze SIP on June 7, 2012 (77 FR 33642), triggering the
requirement for EPA to promulgate a FIP unless Indiana submitted, and
EPA approved a SIP revision that corrected the deficiency. EPA
finalized a limited approval of Indiana's regional haze SIP on June 11,
2012 (77 FR 34218), as meeting the remaining applicable regional haze
requirements set forth in the CAA and the RHR.
In the June 7, 2012 limited disapproval action, EPA also amended
the RHR to provide that participation by a state's EGUs in a CSAPR
trading
[[Page 23506]]
program for a given pollutant--either a CSAPR Federal trading program
implemented through a CSAPR FIP or an integrated CSAPR state trading
program implemented through an approved CSAPR SIP revision--qualifies
as a BART alternative for those EGUs for that pollutant.\3\ See 40 CFR
51.308(e)(4). Since EPA promulgated this amendment, numerous states
covered by CSAPR, including Indiana, have utilized the provision
through either SIPs or FIPs.\4\
---------------------------------------------------------------------------
\3\ Legal challenges to the CSAPR-Better-than-BART rule from
state, industry, and other petitioners are pending. Utility Air
Regulatory Group v. EPA, No. 12-1342 (D.C. Cir. filed August 6,
2012).
\4\ EPA has promulgated FIPs relying on CSAPR participation for
BART purposes for Georgia, Indiana, Iowa, Kentucky, Michigan,
Missouri, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia,
and West Virginia, 77 FR at 33654, and Nebraska, 77 FR 40150, 40151
(July 6, 2012), and Texas 82 FR 48324 (October 17, 2017). EPA has
approved Minnesota's, Wisconsin's, and Alabama's SIPs relying on
CSAPR participation for BART purposes. See 77 FR 34801 (June 12,
2012) for Minnesota, 77 FR 46952 (August 7, 2012) for Wisconsin, and
82 FR 47393 (October 12, 2017) for Alabama.
---------------------------------------------------------------------------
Numerous parties filed petitions for review of CSAPR in the D.C.
Circuit, and on August 21, 2012, the court issued its ruling, vacating
and remanding CSAPR to EPA and ordering continued implementation of
CAIR. EME Homer City Generation, L.P. v. EPA, 696 F.3d 7, 38 (D.C. Cir.
2012). The D.C. Circuit's vacatur of CSAPR was reversed by the United
States Supreme Court on April 29, 2014, and the case was remanded to
the D.C. Circuit to resolve remaining issues in accordance with the
high court's ruling. EPA v. EME Homer City Generation, L.P., 134 S. Ct.
1584 (2014). On remand, the D.C. Circuit affirmed CSAPR in most
respects, but invalidated without vacating some of the CSAPR budgets as
to a number of states. EME Homer City Generation, L.P. v. EPA, 795 F.3d
118 (D.C. Cir. 2015).
The remanded budgets include the Phase 2 SO2 emissions
budgets for four states and the Phase 2 ozone-season NOX
budgets for eleven states. This litigation ultimately delayed
implementation of CSAPR for three years, from January 1, 2012, when
CSAPR's cap-and-trade programs were originally scheduled to replace the
CAIR cap-and-trade programs, to January 1, 2015. Thus, the rule's Phase
2 budgets that were originally scheduled to begin on January 1, 2014,
began on January 1, 2017.
On September 29, 2017 (82 FR 45481), EPA published a final rule
affirming the continued validity of the Agency's 2012 determination
that participation in CSAPR meets the RHR's criteria for an alternative
to the application of source specific BART. In the rulemaking, EPA
explained that the limited changes to the scope of CSAPR coverage did
not alter EPA's conclusion that CSAPR remains ``better-than-BART;''
that is, that participation in CSAPR remains available as an
alternative to BART for EGUs covered by the trading program.
Indiana's November 27, 2017 SIP submittal seeks to correct the
deficiencies identified in the June 7, 2012 limited disapproval of its
regional haze SIP by replacing reliance on CAIR with reliance on CSAPR.
Specifically, Indiana requests that EPA approve the State's regional
haze SIP revision that replaces reliance on CAIR with CSAPR to satisfy
SO2 and NOX BART requirements.
B. Infrastructure SIPs
The ``infrastructure SIP'' 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. The requirement for states to make an infrastructure SIP
submission is under CAA section 110(a)(1). SIPs meeting the
requirements of sections 110(a)(1) and (2) of the CAA are required to
be submitted by states within three years (or less, if the
Administrator so prescribes) after promulgation of a new or revised
NAAQS to provide for the implementation, maintenance, and enforcement
of the new or revised NAAQS. EPA has historically referred to these SIP
submissions made for the purpose of satisfying the requirements of
sections 110(a)(1) and 110(a)(2) as ``infrastructure SIP'' submissions.
Sections 110(a)(1) and (2) require states to address basic SIP elements
such as for monitoring, basic program requirements, and legal authority
that are designed to assure attainment and maintenance of the newly
established or revised NAAQS. More specifically, section 110(a)(1)
provides the procedural and timing requirements for infrastructure
SIPs. Section 110(a)(2) lists specific elements that states must meet
for the infrastructure SIP requirements related to a newly established
or revised NAAQS. The contents of an infrastructure SIP submission may
vary depending upon the data and analytical tools available to the
state, as well as the provisions already contained in the state's
implementation plan at the time in which the state develops and submits
the submission for a new or revised NAAQS.
Section 110(a)(2)(D) has two components: 110(a)(2)(D)(i) and
110(a)(2)(D)(ii). Section 110(a)(2)(D)(i) includes four distinct
components, commonly referred to as ``prongs,'' that must be addressed
in infrastructure SIP submissions. The first two prongs, which are
codified in section 110(a)(2)(D)(i)(I), prohibit any source or other
type of emissions activity in one state from contributing significantly
to nonattainment of the NAAQS in another state (prong 1) and from
interfering with maintenance of the NAAQS in another state (prong 2).
The third and fourth prongs, which are codified in section
110(a)(2)(D)(i)(II), prohibit emissions activity in one state from
interfering with measures required to prevent significant deterioration
of air quality in another state (prong 3) or from interfering with
measures to protect visibility in another state (prong 4).
``Prong 4'' Requirements
Section 110(a)(2)(D)(i)(II) requires a state's implementation plan
to contain provisions prohibiting sources in that state from emitting
pollutants in amounts that interfere with any other state's efforts to
protect visibility under part C of the CAA (which includes sections
169A and 169B). EPA issued guidance on infrastructure SIPs in a
September 13, 2013 memorandum from Stephen D. Page titled ``Guidance on
Infrastructure State Implementation Plan (SIP) Elements under Clean Air
Act Sections 110(a)(1) and 110(a)(2)'' (2013 Guidance). The 2013
Guidance states that these prong 4 requirements can be satisfied by
approved SIP provisions that EPA has found to adequately address any
contribution of that state's sources that impact the visibility program
requirements in other states. The 2013 Guidance also states that EPA
interprets this prong to be pollutant-specific, such that the
infrastructure SIP submission need only address the potential for
interference with protection of visibility caused by the pollutant
(including precursors) to which the new or revised NAAQS applies.
The 2013 Guidance lays out how a state's infrastructure SIP may
satisfy prong 4. One way is via confirmation that the state has an
approved regional haze SIP that fully meets the requirements of 40 CFR
51.308 or 51.309. The regulations at 40 CFR 51.308 and 51.309
specifically require that a state participating in a regional planning
process include all measures needed to achieve its apportionment of
emission reduction obligations agreed upon through that process. A
fully approved regional haze SIP will ensure that emissions from
sources under an air agency's jurisdiction are not interfering
[[Page 23507]]
with measures required to be included in other air agencies' plans to
protect visibility.
Alternatively, in the absence of a fully approved regional haze
SIP, a state may meet the requirements of prong 4 through a
demonstration in its infrastructure SIP submission that emissions
within its jurisdiction do not interfere with other air agencies' plans
to protect visibility. Such an infrastructure SIP submission would need
to include measures to limit visibility-impairing pollutants and ensure
that the reductions conform with any mutually agreed upon regional haze
RPGs for mandatory Class I areas in other states.
Through this action, EPA is proposing to approve the prong 4
portion of Indiana's infrastructure SIP submissions for the 2012
PM2.5, 2010 NO2, and 2010 SO2
standards, and to convert EPA's disapproval of the prong 4 portion of
Indiana's infrastructure SIP submission for the 2008 ozone NAAQS to an
approval, as discussed in section IV of this action. All other
applicable infrastructure SIP requirements for these SIP submissions
have been or will be addressed in separate rulemakings. A brief
background regarding the NAAQS relevant to this proposal is provided
below.
1. 2006 and 2012 PM2.5 NAAQS
On December 18, 2006, EPA revised the 24-hour average primary and
secondary PM2.5 NAAQS to 35 micrograms per cubic meter
([mu]g/m\3\). See 71 FR 61144 (October 17, 2006). States were required
to submit infrastructure SIP submissions for the 2006 PM2.5
NAAQS to EPA no later than September 21, 2009. Indiana submitted
infrastructure SIP submissions for the 2006 PM2.5 NAAQS on
October 20, 2009, June 25, 2012, July 12, 2012, and May 22, 2013. This
proposed action only addresses the prong 4 element of those
submissions. The other portions of Indiana's PM2.5
infrastructure submissions have been previously addressed (78 FR 41311,
July 10, 2013; 79 FR 18999, April 7, 2014; and 83 FR 64472, December
17, 2018).
On December 14, 2012, EPA revised the annual primary
PM2.5 NAAQS to 12 [mu]g/m\3\. See 78 FR 3086 (January 15,
2013). States were required to submit infrastructure SIP submissions
for the 2012 PM2.5 NAAQS to EPA no later than December 14,
2015. Indiana submitted an infrastructure SIP submission for the 2012
PM2.5 NAAQS on December 10, 2016. This proposed action only
addresses the prong 4 element of that submission. The other portions of
Indiana's December 10, 2016 PM2.5 infrastructure submission
have been previously addressed (83 FR 4595, February 1, 2018) or will
be addressed in a separate action.
2. 2010 SO2 NAAQS
On June 2, 2010, EPA revised the primary SO2 NAAQS to an
hourly standard of 75 parts per billion (ppb) based on a 3-year average
of the annual 99th percentile of 1-hour daily maximum concentrations.
See 75 FR 35520 (June 22, 2010). States were required to submit
infrastructure SIP submissions for the 2010 SO2 NAAQS to EPA
no later than June 2, 2013. Indiana submitted an infrastructure SIP
submission for the 2010 1-hour SO2 NAAQS on May 22, 2013.
This proposed action only addresses the prong 4 element of that
submission. The other portions of Indiana's May 22, 2013 SO2
infrastructure submission have been previously addressed (80 FR 48733,
August 14, 2015) or will be addressed in a separate action.
3. 2010 NO2 NAAQS
On January 22, 2010, EPA promulgated a new 1-hour primary NAAQS for
NO2 at a level of 100 ppb, based on a 3-year average of the
98th percentile of the yearly distribution of 1-hour daily maximum
concentrations. See 75 FR 6474 (February 9, 2010). States were required
to submit infrastructure SIP submissions for the 2010 NO2
NAAQS to EPA no later than January 22, 2013. Indiana submitted
infrastructure SIP submissions for the 2010 NO2 NAAQS on
January 15, 2013. This proposed action only addresses the prong 4
element of that submission. The other portions of Indiana's January 15,
2013, NO2 infrastructure submission have been addressed in a
previous EPA action (80 FR 48733, August 14, 2015).
4. 2008 Ozone NAAQS
On March 12, 2008, EPA revised the ozone NAAQS to 0.075 parts per
million. See 73 FR 16436 (March 27, 2008). States were required to
submit infrastructure SIP submissions for the 2008 ozone NAAQS to EPA
no later than March 12, 2011. Indiana submitted an infrastructure SIP
for the 2008 ozone NAAQS on December 12, 2011. On June 15, 2016, EPA
disapproved the intrastate transport provisions of Indiana's 2008 ozone
infrastructure submission, including the prong 4 element. See 81 FR
53309. This proposed action addresses the disapproval for prong 4 and
proposes to convert it to a full approval. The other portions of
Indiana's December 12, 2011 ozone infrastructure SIP submission have
been addressed in a previous EPA action (80 FR 23713, April 29, 2015).
II. What is EPA's analysis of how Indiana addressed regional haze and
prong 4 of the infrastructure SIP requirements?
Indiana submitted infrastructure SIPs for the following NAAQS: 2012
annual PM2.5 (December 10, 2016); 2006 24-hour average
PM2.5 (October 20, 2009; June 25, 2012; July 12, 2012; and
May 22, 2013); 2010 NO2 (January 15, 2013); 2010
SO2 (May 22, 2013); and 2008 ozone (December 12, 2011) which
relied on the State having a fully approved regional haze SIP to
satisfy its prong 4 requirements. However, EPA had not previously fully
approved Indiana's regional haze SIP. As discussed earlier in this
action, the Agency issued a limited disapproval of the State's original
regional haze plan on June 7, 2012, due to its reliance on CAIR, which
also triggered the requirement for EPA to promulgate a FIP in Indiana
utilizing CSAPR. To correct the deficiencies in its regional haze SIP
and obtain approval of the aforementioned infrastructure SIPs that rely
on the regional haze SIP, the State submitted a SIP revision on
November 27, 2017, to replace reliance on CAIR with reliance on CSAPR.
As noted above, EPA determined that CSAPR remains ``better than
BART,'' given the changes to CSAPR's scope in response to the D.C.
Circuit's remand. Because the Agency has finalized the ``CSAPR remains
better-than-BART'' rulemaking, EPA is proposing to approve the regional
haze portion of the State's November 27, 2017 SIP revision and convert
EPA's previous action on Indiana's regional haze SIP from a limited
approval/limited disapproval to a full approval. Specifically, EPA's
finds that this portion of Indiana's November 27, 2017 SIP revision
satisfies the SO2 and NOX BART requirements for
EGUs formerly subject to CAIR. Because a state may satisfy prong 4
requirements through a fully approved regional haze SIP, EPA is also
proposing to approve the prong 4 portion of Indiana's 2006 and 2012
PM2.5 submissions; 2010 NO2 submissions; and the
2010 SO2 submission. EPA is also proposing to convert EPA's
disapproval of the prong 4 portions of Indiana's 2008 ozone
infrastructure submission to an approval.
III. Proposed Action
EPA is proposing to take the following actions: (1) Approve the
portion of Indiana's November 27, 2017 SIP submittal seeking to change
from reliance on CAIR to reliance on CSAPR for certain regional haze
requirements;
[[Page 23508]]
(2) convert EPA's limited approval/limited disapproval of Indiana's
January 14, 2011 and March 10, 2011 regional haze SIP to a full
approval; (3) withdraw the FIP provisions that address the limited
disapproval; (4) approve the visibility prong of Indiana's
infrastructure SIP submittals for the 2012 and 2006 PM2.5,
2010 NO2, and 2010 SO2 NAAQS; and (5) convert
EPA's disapproval of the visibility portion of Indiana's infrastructure
SIP submittal for the 2008 ozone NAAQS to an approval.
All other applicable infrastructure requirements for the
infrastructure SIP submissions have been or will be addressed in
separate rulemakings.
IV. Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the CAA and applicable
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in
reviewing SIP submissions, EPA's role is to approve state choices,
provided that they meet the criteria of the CAA. Accordingly, this
action merely approves state law as meeting Federal requirements and
does not impose additional requirements beyond those imposed by state
law. For that reason, this action:
Is not a significant regulatory action subject to review
by the Office of Management and Budget under Executive Orders 12866 (58
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
Is not an Executive Order 13771 (82 FR 9339, February 2,
2017) regulatory action because SIP approvals are exempted under
Executive Order 12866.
Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
Does not have Federalism implications as specified in
Executive 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, 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).
