Air Plan Approval; Wisconsin; NOX as a Precursor to Ozone, PM2.5
Increment Rules and PSD Infrastructure SIP Requirements
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing
approval of a revision to Wisconsin's state implementation plan (SIP),
revising portions of the State's Prevention of Significant
Deterioration (PSD) and ambient air quality programs to address
deficiencies identified in EPA's previous narrow infrastructure SIP
disapprovals and Finding of Failure to Submit. This SIP revision
request is consistent with the Federal PSD rules and addresses the
required elements of the fine particulate matter (PM2.5) PSD
Increments, Significant Impact Levels (SILs) and Significant Monitoring
Concentration (SMC) Rule. EPA is also proposing to approve elements of
SIP submissions from Wisconsin regarding PSD infrastructure
requirements of section 110 of the Clean Air Act (CAA) for the 1997
PM2.5, 1997 ozone, 2006 PM2.5, 2008 lead, 2008
ozone, 2010 nitrogen dioxide (NO2), 2010 sulfur dioxide
(SO2), and 2012 PM2.5 National Ambient Air
Quality Standards (NAAQS). 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.

I. What is the background of these SIP submissions?
On August 8, 2016, the Wisconsin Department of Natural Resources
(WDNR) submitted a SIP revision request to EPA to revise portions of
its PSD and ambient air quality programs to address deficiencies
identified in EPA's previous narrow infrastructure SIP disapprovals and
Finding of Failure to Submit (FFS). Final approval of this SIP revision
request will be consistent with the Federal PSD requirements and will
address the required elements of the PM2.5 PSD Increments,
SILs and SMC Rule. Wisconsin submitted revisions to its rules NR 404
and 405 of the Wisconsin Administrative Code. The submittal requests
that EPA approve the following revisions to Wisconsin's SIP: (1) Amend
NR 404.05 (2) (intro); (2) create NR 404.05(2) (am); (3) amend NR
404.05(3) (intro); (4) create NR 404.05(3) (am); (5) amend NR 404.05(4)
(intro); (6) create NR 404.05(4) (am); (7) amend NR 405.02(3), (21)(a),
and (21m)(a); (8) create NR 405.02(21m)(c); (9) amend NR 405.02(22)(b)
and (22m)(a)1. and (b)1.; (10) create NR 405.02(22m)(a)3.; (11) amend
NR 405.02(27)(a)6.; (12) amend NR 405.07(8)(a)3m; (13) create NR
405.07(8)(a)3m (Note); and (14) amend NR 405.07(8)(a)5. (Note).
WDNR also requested that this SIP revision supplement the PSD
portions of its previously submitted infrastructure submittals,
including 1997 PM2.5, 1997 ozone, 2006 PM2.5,
2008 lead, 2008 ozone, 2010 NO2, SO2, and 2012
PM2.5.
A. PSD Rule Revisions
1. PM2.5 Increments
To implement the PM2.5 NAAQS, EPA issued two separate
final rules that establish the New Source Review (NSR) permitting
requirements for PM2.5: The NSR PM2.5
Implementation Rule promulgated on May 16, 2008 (73 FR 28321), and the
PM2.5 PSD Increments, SILs and SMC Rule promulgated on
October 20, 2010 (75 FR 64864). EPA's 2008 NSR PM2.5
Implementation Rule required states to submit applicable SIP revisions
to EPA no later than May 16, 2011, to address this rule's PSD and
nonattainment NSR SIP requirements. This rule requires that the state
submit revisions to its SIP, including the identification of precursors
for PM2.5, the significant emissions rates for
PM2.5 and the requirement to include emissions which may
condense to form particulate matter at ambient temperatures, known as
condensables, in permitting decisions. EPA published a final approval
of a revision to Wisconsin's SIP on October 16, 2014, (79 FR 62008),
which included all of the required elements of the 2008 NSR
Implementation Rule.
The PM2.5 PSD Increments, SILs and SMC Rule required
states to submit SIP revisions to EPA by July 20, 2012, adopting
provisions equivalent to or at least as stringent as the
PM2.5 PSD increments and associated implementing
regulations. On August 11, 2014, EPA published a finding that Wisconsin
had failed to submit the required elements of the PM2.5 PSD
Increments, SILs and SMC Rule (79 FR 46703).
The PM2.5 PSD Increments, SILs and SMC Rule also allows
states to discretionarily adopt and submit for EPA approval: (1) SILs,
which are used as a screening tool to evaluate the impact a proposed
new major source or major modification may have on the NAAQS or PSD
increment; and (2) a SMC (also a screening tool), which is used to
determine the subsequent level of data gathering required for a PSD
permit application for emissions of PM2.5. However, on
January 22, 2013, the United States Court of Appeals for the District
of Columbia (Court) granted a request from EPA to vacate and remand to
EPA the portions of the PM2.5 PSD Increments, SILs and SMC
Rule PM2.5 addressing the SILs for PM2.5 so that
EPA could voluntarily correct an error in these provisions. The Court
also vacated parts of the PM2.5 PSD Increments, SILs and SMC
Rule establishing a PM2.5 SMC, finding that EPA was
precluded from using the PM2.5 SMCs to exempt permit
applicants from the statutory requirement to compile preconstruction
monitoring data. Sierra Club v. EPA, 705 F.3d 458, 463-69. On December
9, 2013, EPA issued a good cause final rule formally removing the
affected SILs and replacing the SMC with a numeric value of 0
micrograms per cubic meter ([mu]g/m\3\) and a note that no exemption is
available with regard to PM2.5. See 78 FR 73698. As a
result, SIP submittals could no longer include the vacated
PM2.5 SILs at 40 CFR 51.166(k)(2) and 52.21(k)(2) and the
PM2.5 SMC must be revised to 0 [mu]g/m\3\, consistent with
40 CFR 51.166(i)(5)(i)(c) and 52.21(i)(5)(i)(c).
2. Ozone
On November 29, 2005, EPA published (70 FR 71612) in the Federal
Register the ``Final Rule to Implement the 8-Hour Ozone National
Ambient Air Quality Standard--Phase 2''. Part of this rule established,
among other requirements, oxides of nitrogen (NOX) as a
precursor to ozone. The final rule became effective on January 30,
2006.
On October 6, 2015, EPA finalized approval of revisions to
Wisconsin's SIP that included the identification of NOX as a
precursor to ozone in the definition of regulated NSR pollutant. See 79
FR 60064.
B. Infrastructure SIP Submittals
The requirement for states to make a SIP submission of this type
arises out of CAA section 110(a)(1). Pursuant to section 110(a)(1),
states must make SIP submissions ``within 3 years (or such shorter
period as the Administrator may prescribe) after the promulgation of a
national primary ambient air quality standard (or any revision
thereof),'' and these SIP submissions are to provide for the
``implementation, maintenance, and enforcement'' of such NAAQS. The
statute directly imposes on states the duty to make these SIP
submissions, and the requirement to make the submissions is not
conditioned upon EPA's taking any action other than promulgating a new
or revised NAAQS. Section 110(a)(2) includes a list of specific
elements that ``[e]ach such plan'' submission must address.
This specific rulemaking is only taking action on the PSD elements
of the Wisconsin infrastructure submittals.
[[Page 67263]]
Separate action has been or will be taken on the non-PSD infrastructure
elements in separate rulemakings. The infrastructure elements for PSD
are found in CAA 110(a)(2)(C), 110(a)(2)(D), and 110(a)(2)(J) and will
be discussed in detail below. For further discussion on the background
of infrastructure submittals, see 77 FR 45992.
II. What is EPA's review of these SIP submissions?
A. PSD Rule Revisions
EPA has evaluated WDNR's proposed revision to the Wisconsin SIP in
accordance with the Federal requirements governing state permitting
programs. The revisions described in section I above are intended to
update the Wisconsin SIP to comply with the current rules and address
deficiencies identified by EPA in its previous SIP disapprovals. As
discussed below, EPA is proposing to approve these revisions because
they meet Federal requirements.
1. PM2.5
The PM2.5 PSD Increments, SILs and SMC Rule finalized
several new requirements for states to revise their SIPs to incorporate
increments for PM2.5. Specifically, the rule requires a
state's submitted PSD SIP revision to adopt and submit for EPA approval
the PM2.5 increments issued pursuant to section 166(a) of
the CAA to prevent significant deterioration of air quality in areas
meeting the NAAQS. States were also required to adopt and submit for
EPA approval revisions to the definitions for ``major source baseline
date,'' ``minor source baseline date,'' and ``baseline area'' as part
of the implementing regulations for the PM2.5 increments.
The PM2.5 increments are codified in 40 CFR 51.166(c)(1) and
40 CFR 52.21(c)(1). For class I areas the maximum allowable increase is
codified as 1 [mu]g/m\3\ determined on an annual arithmetic mean, and a
24-hr maximum of 2 [mu]g/m\3\. For class II areas the maximum allowable
increase is 4 [mu]g/m\3\ determined on an annual arithmetic mean, and a
24-hr maximum of 9 [mu]g/m\3\. For class III areas the maximum
allowable increase is 8 [mu]g/m\3\ determined on an annual arithmetic
mean, and a 24-hr maximum of 18 [mu]g/m\3\. Wisconsin incorporated
these maximum allowable increases for PM2.5 into their rules
at NR 404.05(2) (intro) and (am); NR 404.05(3) (intro) and (am); and NR
404.05(4) (intro) and (am) for the class I, class II, and class III
increments, respectively. As Wisconsin has utilized the same maximum
allowable increases as the Federal regulations, their revisions are
found to be consistent with the Federal regulations.
States were also required to adopt and submit for EPA approval
revisions to the definitions for ``major source baseline date,''
``minor source baseline date,'' and ``baseline area'' as part of the
implementing regulations for the PM2.5 increments.
Wisconsin's revisions to the definition of ``major source baseline
date,'' at NR 405.02(21m)(a) and (c), clarifies that the baseline date
for particulate matter less than 10 micrometers (PM10) is
January 6, 1975, and adds October 20, 2010, as the major source
baseline date for PM2.5. This is consistent with the Federal
definition at 40 CFR 51.166(b)(14)(i). Wisconsin's revisions to the
definition of ``minor source baseline date'' at NR 405.02(22m)(a)1. and
3., clarify that the trigger date for PM10 is January 6,
1975, and establish October 20, 2011, as the trigger date for
PM2.5. The revisions to NR 405.02(22m)(b)(1) revise the
definition of baseline date to update references to the U.S. Code of
Federal Regulations. These revisions are consistent with the definition
of ``minor source baseline date'' at 40 CFR 51.166(b)(14)(ii). The
State revised the definition of ``Baseline area'' at NR 405.02(3) to
explicitly identify pollutant air quality impacts that would define a
baseline area where a minor source baseline date is already
established. This revision is consistent with 40 CFR
51.166(b)(14)(ii)(c).
Wisconsin also revised provisions pertaining to the
PM2.5 SMC to be consistent with Federal requirements after
the January 22, 2013, Court decision. WDNR's revision to NR
405.07(8)(a)3m. revises the PM2.5 SMC to 0 [mu]g/m\3\ and NR
405.07(8)(a)3m.(Note) adds a note that no exemption is available with
regard to PM2.5. These revisions are consistent with the
language in 40 CFR 51.166(i)(5)(i)(c) regarding the SMC for
PM2.5.
2. Ozone
The ``Final Rule to Implement the 8-Hour Ozone National Ambient Air
Quality Standard--Phase 2'' required states to make revisions to their
PSD programs to establish NOX as a precursor to ozone.
Specifically, NOX was required to be identified as a
precursor to ozone in the definition of major stationary source, the
definition of major modification, the definition of significant, the
definition of regulated NSR pollutant, and the SMC for ozone.
Wisconsin's revisions to the definition of ``major modification''
in NR 405.02(21)(a) states that any net emission increase at major
stationary source that is significant for NOX or volatile
organic compounds (VOCs) shall be considered significant for ozone.
This is consistent with the Federal requirements of 40 CFR
51.166(b)(2)(ii). Wisconsin's revisions to the definition of ``Major
Stationary Source'' at NR 405.02(22)(b) add that a major stationary
source that is major for NOX shall be considered major for
ozone. This is consistent with the Federal definition at 40 CFR
51.166(b)(1). Wisconsin's revisions to NR 405.07(8)(a)5.(note) revise
the SMC for ozone to provide that sources with a net increase of 100
tons per year of NOX need to perform an ambient impact
analysis for ozone. This matches the note at 40 CFR
51.166(i)(5)(i)(f).\1\ The revisions to the definition of
``Significant'' at NR 405.02(27)(a)6. adds a significant emission rate
for ozone of 40 tons per year of nitrogen oxides. This is consistent
with the Federal requirements of 40 CFR 51.166(b)(23)(i).
Because Wisconsin's requested revisions are consistent with the
applicable requirements found in Federal regulations, EPA is proposing
to approve the requested revisions.
B. Infrastructure SIP Submittals
PSD infrastructure elements are addressed in different sections of
the CAA: Sections 110(a)(2)(C), 110(a)(2)(D)(i)(II), and 110(a)(2)(J).
1. Section 110(a)(2)(C)--Program for Enforcement of Control Measures;
PSD
States are required to include a program providing for enforcement
of all SIP measures and the regulation of construction of new or
modified stationary sources to meet NSR requirements under PSD and
nonattainment new source review (NNSR) programs. Part C of the CAA
(sections 160-169B) addresses PSD, while part D of the CAA (sections
171-193) addresses NNSR requirements.
The evaluation of each state's submission addressing the
infrastructure SIP requirements of section 110(a)(2)(C) covers: (i)
Enforcement of SIP measures; (ii) PSD provisions that explicitly
identify NOX as a precursor to ozone in the PSD program;
(iii) identification of precursors to PM2.5 and the
identification of PM2.5 and PM10 \1\ condensables
in the PSD program; (iv) PM2.5 increments in the PSD
program;
[[Page 67264]]
and, (v) Greenhouse Gas (GHG) permitting and the ``Tailoring Rule.''
\2\
---------------------------------------------------------------------------
\1\ PM10 refers to particles with diameters less than
10 microns, oftentimes referred to as ``coarse'' particles.
\2\ EPA highlights this statutory requirement in an October 2,
2007, guidance document entitled ``Guidance on SIP Elements Required
Under Sections 110(a)(1) and (2) for the 1997 8-hour Ozone and
PM2.5 National Ambient Air Quality Standards'' and has
issued additional guidance documents, the most recent on September
13, 2013, ``Guidance on Infrastructure State Implementation Plan
(SIP) Elements under Clean Air Act Sections 110(a)(1) and (2)''
(2013 memo).
---------------------------------------------------------------------------
(i) Enforcement of SIP Measures
The enforcement of SIP measures provision was approved in previous
rulemakings.
(ii) PSD Provisions That Explicitly Identify NOX as a
Precursor to Ozone in the PSD Program
EPA's ``Final Rule to Implement the 8-Hour Ozone National Ambient
Air Quality Standard--Phase 2; Final Rule to Implement Certain Aspects
of the 1990 Amendments Relating to New Source Review and Prevention of
Significant Deterioration as They Apply in Carbon Monoxide, Particulate
Matter, and Ozone NAAQS; Final Rule for Reformulated Gasoline'' (Phase
2 Rule) was published on November 29, 2005 (see 70 FR 71612). Among
other requirements, the Phase 2 Rule obligated states to revise their
PSD programs to explicitly identify NOX as a precursor to
ozone (70 FR 71612 at 71679, 71699-71700). This requirement was
codified in 40 CFR 51.166.
The Phase 2 Rule required that states submit SIP revisions
incorporating the requirements of the rule, including those identifying
NOX as a precursor to ozone, by June 15, 2007 (see 70 FR
71612 at 71683, November 29, 2005).
EPA is proposing to approve revisions to Wisconsin's PSD SIP
reflecting these requirements in today's rulemaking, and therefore is
proposing to find that Wisconsin has met this set of infrastructure SIP
requirements of section 110(a)(2)(C) with respect to the 1997
PM2.5, 1997 ozone, 2006 PM2.5, 2008 lead, 2008
ozone, 2010 NO2, 2010 SO2, and 2012
PM2.5 NAAQS.
(iii) Identification of Precursors to PM2.5 and the
Identification of PM2.5 and PM10 Condensables in
the PSD Program
On May 16, 2008 (see 73 FR 28321), EPA issued the Final Rule on the
``Implementation of the New Source Review Program for Particulate
Matter Less than 2.5 Micrometers'' (2008 NSR Rule). The 2008 NSR Rule
finalized several new requirements for SIPs to address sources that
emit direct PM2.5 and other pollutants that contribute to
secondary PM2.5 formation. One of these requirements is for
NSR permits to address pollutants responsible for the secondary
formation of PM2.5, otherwise known as precursors. In the
2008 rule, EPA identified precursors to PM2.5 for the PSD
program to be SO2 and NOX (unless the state
demonstrates to the Administrator's satisfaction or EPA demonstrates
that NOX emissions in an area are not a significant
contributor to that area's ambient PM2.5 concentrations).
The 2008 NSR Rule also specifies that VOCs are not considered to be
precursors to PM2.5 in the PSD program unless the state
demonstrates to the Administrator's satisfaction or EPA demonstrates
that emissions of VOCs in an area are significant contributors to that
area's ambient PM2.5 concentrations.
The explicit references to SO2, NOX, and VOCs
as they pertain to secondary PM2.5 formation are codified at
40 CFR 51.166(b)(49)(i)(b) and 40 CFR 52.21(b)(50)(i)(b). As part of
identifying pollutants that are precursors to PM2.5, the
2008 NSR Rule also required states to revise the definition of
``significant'' as it relates to a net emissions increase or the
potential of a source to emit pollutants. Specifically, 40 CFR
51.166(b)(23)(i) and 40 CFR 52.21(b)(23)(i) define ``significant'' for
PM2.5 to mean the following emissions rates: 10 Tons per
year (tpy) of direct PM2.5; 40 tpy of SO2; and 40
tpy of NOX (unless the state demonstrates to the
Administrator's satisfaction or EPA demonstrates that NOX
emissions in an area are not a significant contributor to that area's
ambient PM2.5 concentrations). The deadline for states to
submit SIP revisions to their PSD programs incorporating these changes
was May 16, 2011 (see 73 FR 28321 at 28341).\3\
---------------------------------------------------------------------------
\3\ EPA notes that on January 4, 2013, the U.S. Court of Appeals
for the D.C. Circuit, in Natural Resources Defense Council v. EPA,
706 F.3d 428 (D.C. Cir.), held that EPA should have issued the 2008
NSR Rule in accordance with the CAA's requirements for
PM10 nonattainment areas (Title I, Part D, subpart 4),
and not the general requirements for nonattainment areas under
subpart 1. As the subpart 4 provisions apply only to nonattainment
areas, EPA does not consider the portions of the 2008 rule that
address requirements for PM2.5 attainment and
unclassifiable areas to be affected by the court's opinion.
Moreover, EPA does not anticipate the need to revise any PSD
requirements promulgated by the 2008 NSR Rule in order to comply
with the court's decision. Accordingly, EPA's approval of
Wisconsin's infrastructure SIP as to elements (C), (D)(i)(II), or
(J) with respect to the PSD requirements promulgated by the 2008
implementation rule does not conflict with the court's opinion.
The court's decision with respect to the nonattainment NSR
requirements promulgated by the 2008 implementation rule also does
not affect EPA's action on the present infrastructure action. EPA
interprets the CAA to exclude nonattainment area requirements,
including requirements associated with a nonattainment NSR program,
from infrastructure SIP submissions due three years after adoption
or revision of a NAAQS. Instead, these elements are typically
referred to as nonattainment SIP or attainment plan elements, which
would be due by the dates statutorily prescribed under subparts 2
through 5 under part D, extending as far as 10 years following
designations for some elements.
---------------------------------------------------------------------------
The 2008 NSR Rule did not require states to immediately account for
gases that could condense to form particulate matter, known as
condensables, in PM2.5 and PM10 emission limits
in NSR permits. Instead, EPA determined that states had to account for
PM2.5 and PM10 condensables for applicability
determinations and in establishing emissions limitations for
PM2.5 and PM10 in PSD permits beginning on or
after January 1, 2011. This requirement is codified in 40 CFR
51.166(b)(49)(i)(a) and 40 CFR 52.21(b)(50)(i)(a). Revisions to states'
PSD programs incorporating the inclusion of condensables were required
be submitted to EPA by May 16, 2011 (see 73 FR 28321 at 28341).
EPA approved revisions to Wisconsin's PSD SIP reflecting these
requirements on October 16, 2014 (see 79 FR 62008), and therefore
proposes that Wisconsin has met this set of infrastructure SIP
requirements of section 110(a)(2)(C) with respect to the 1997
PM2.5, 1997 ozone, 2006 PM2.5, 2008 lead, 2008
ozone, 2010 NO2, 2010 SO2, and 2012
PM2.5 NAAQS.
(iv) PM2.5 Increments in the PSD Program
On October 20, 2010, EPA issued the final rule on the ``Prevention
of Significant Deterioration for Particulate Matter Less Than 2.5
Micrometers--Increments, Significant Impact Levels and Significant
Monitoring Concentration'' (2010 NSR Rule). This rule established
several components for making PSD permitting determinations for
PM2.5, including a system of ``increments,'' which is the
mechanism used to estimate significant deterioration of ambient air
quality for a pollutant. These increments are codified in 40 CFR
51.166(c) and 40 CFR 52.21(c), and are included in the table below.
Table 1--PM2.5 Increments Established by the 2010 NSR Rule in Micrograms
per Cubic Meter
------------------------------------------------------------------------
Annual
arithmetic 24-hour
mean max
------------------------------------------------------------------------
Class I....................................... 1 2
Class II...................................... 4 9
Class III..................................... 8 18
------------------------------------------------------------------------
[[Page 67265]]
The 2010 NSR Rule also established a new ``major source baseline
date'' for PM2.5 as October 20, 2010, and a new trigger date
for PM2.5 as October 20, 2011. These revisions are codified
in 40 CFR 51.166(b)(14)(i)(c) and (b)(14)(ii)(c), and 40 CFR
52.21(b)(14)(i)(c) and (ii)(c). Lastly, the 2010 NSR Rule revised the
definition of ``baseline area'' to include a level of significance of
0.3 micrograms per cubic meter, annual average, for PM2.5.
This change is codified in 40 CFR 51.166(b)(15)(i) and 40 CFR
52.21(b)(15)(i).
EPA is proposing to approve revisions to Wisconsin's PSD SIP
reflecting these requirements in today's rulemaking, and therefore is
proposing to find that Wisconsin has met this set of infrastructure SIP
requirements for section 110(a)(2)(C) with respect to the 1997
PM2.5, 1997 ozone, 2006 PM2.5, 2008 lead, 2008
ozone, 2010 NO2, 2010 SO2, and 2012
PM2.5 NAAQS.
(v) GHG Permitting and the ``Tailoring Rule''
With respect to CAA Sections 110(a)(2)(C) and (J), EPA interprets
the CAA to require each state to make an infrastructure SIP submission
for a new or revised NAAQS that demonstrates that the air agency has a
complete PSD permitting program meeting the current requirements for
all regulated NSR pollutants. The requirements of section
110(a)(2)(D)(i)(II) may also be satisfied by demonstrating the air
agency has a complete PSD permitting program correctly addressing all
regulated NSR pollutants. Wisconsin has shown that it currently has a
PSD program in place that covers all regulated NSR pollutants,
including GHGs.
On June 23, 2014, the United States Supreme Court issued a decision
addressing the application of PSD permitting requirements to GHG
emissions. Utility Air Regulatory Group v. Environmental Protection
Agency, 134 S.Ct. 2427. The Supreme Court said that the EPA may not
treat GHGs as an air pollutant for purposes of determining whether a
source is a major source required to obtain a PSD permit. The Court
also said that the EPA could continue to require that PSD permits,
otherwise required based on emissions of pollutants other than GHGs,
contain limitations on GHG emissions based on the application of Best
Available Control Technology (BACT).
In order to act consistently with its understanding of the Court's
decision, the EPA no longer applies EPA regulations that would require
that SIPs include the permitting requirements that the Supreme Court
found impermissible. Specifically, EPA is not applying the requirement
that a state's SIP-approved PSD program require that sources obtain PSD
permits when GHGs are the only pollutant (i) that the source emits or
has the potential to emit above the major source thresholds, or (ii)
for which there is a significant emissions increase and a significant
net emissions increase from a modification (e.g. 40 CFR
51.166(b)(48)(v)).
EPA anticipates a need to revise Federal PSD rules and for many
states to revise their existing SIP-approved PSD programs in light of
the Supreme Court opinion. The timing and content of subsequent EPA
actions with respect to the EPA regulations and state PSD program
approvals are expected to be informed by additional legal process
before the United States Court of Appeals for the District of Columbia.
At this juncture, EPA is not expecting states to have revised their PSD
programs for purposes of infrastructure SIP submissions and is only
evaluating such submissions to ensure that the state's program
correctly addresses GHGs consistent with the Supreme Court's decision.
At present, EPA is proposing that Wisconsin's SIP is sufficient to
satisfy sections 110(a)(2)(C), (D)(i)(II), and (J) with respect to
GHGs, because the PSD permitting program previously approved by EPA
into the SIP continues to require that PSD permits (otherwise required
based on emissions of pollutants other than GHGs) contain limitations
on GHG emissions based on the application of BACT. Although the
approved Wisconsin PSD permitting program may currently contain
provisions that are no longer necessary in light of the Supreme Court
decision, this does not render the infrastructure SIP submission
inadequate to satisfy Section 110(a)(2)(C), (D)(i)(II), and (J). The
SIP contains the necessary PSD requirements and the application of
those requirements is not impeded by the presence of other previously-
approved provisions regarding the permitting of sources of GHGs that
EPA does not consider necessary at this time in light of the Supreme
Court decision.
For the purposes infrastructure SIPs, EPA reiterates that NSR
Reform regulations are not within the scope of these actions.
Therefore, we are not taking action on existing NSR Reform regulations
for Wisconsin. EPA approved Wisconsin's minor NSR program on January
18, 1995 (see 60 FR 3543); and since that date, WDNR and EPA have
relied on the existing minor NSR program to ensure that new and
modified sources not captured by the major NSR permitting programs do
not interfere with attainment and maintenance of the NAAQS.
Certain sub-elements in this section overlap with elements of
section 110(a)(2)(D)(i) and 110(a)(2)(J). These links will be discussed
in the appropriate areas below.
2. Section 110(a)(2)(D)(i)(II)--Interstate Transport
Section 110(a)(2)(D)(i)(II) requires that SIPs include provisions
prohibiting any source or other type of emissions activity in one state
from interfering with measures required to prevent significant
deterioration of air quality or to protect visibility in another state.
EPA notes that Wisconsin's satisfaction of the applicable
infrastructure SIP PSD requirements for the 1997 PM2.5, 1997
ozone, 2006 PM2.5, 2008 lead, 2008 ozone, 2010
NO2, 2010 SO2, and 2012 PM2.5 NAAQS
have been detailed in the section addressing section 110(a)(2)(C). EPA
further notes that the proposed actions in that section related to PSD
are consistent with the proposed actions related to PSD for section
110(a)(2)(D)(i)(II), and they are reiterated below.
EPA has previously approved or is proposing in today's action to
approve revisions to Wisconsin's SIP that meet certain requirements
required by the Phase 2 Rule and the 2008 NSR Rule. These revisions
included provisions that: Explicitly identify NOX as a
precursor to ozone, explicitly identify SO2 and
NOX as precursors to PM2.5, and regulate
condensable PM2.5 and PM10 in applicability
determinations and in establishing emissions limits. EPA is also
proposing in today's action to approve revisions to Wisconsin's SIP
that incorporate the PM2.5 increments and the associated
implementation regulations including the major source baseline date,
trigger date, and level of significance for PM2.5 per the
2010 NSR Rule. EPA is proposing that Wisconsin's SIP contains
provisions that adequately address the 1997 PM2.5, 1997
ozone, 2006 PM2.5, 2008 lead, 2008 ozone, 2010
NO2, 2010 SO2, and 2012 PM2.5 NAAQS.
States also have an obligation to ensure that sources located in
nonattainment areas do not interfere with a neighboring state's PSD
program. One way that this requirement can be satisfied is through an
NNSR program consistent with the CAA that addresses any pollutants for
which there is a designated nonattainment area within the state.
Wisconsin's EPA-approved NNSR regulations found in Part 2 of the
SIP, specifically in chapter NR 408 of the Wisconsin Administrative
Code, are consistent with 40 CFR 51.165, or 40
[[Page 67266]]
CFR part 51, appendix S. Therefore, EPA proposes that Wisconsin has met
all of the applicable PSD requirements for the 1997 PM2.5,
1997 ozone, 2006 PM2.5, 2008 lead, 2008 ozone, 2010
NO2, 2010 SO2, and 2012 PM2.5 NAAQS
for transport prong 3 related to section 110(a)(2)(D)(i)(II).
3. Section 110(a)(2)(J)--Consultation With Government Officials; Public
Notifications; PSD; Visibility Protection
States must meet applicable requirements of section 110(a)(2)(C)
related to PSD. WDNR's PSD program in the context of infrastructure
SIPs has already been discussed in the paragraphs addressing section
110(a)(2)(C) and 110(a)(2)(D)(i)(II), and EPA notes that the proposed
actions for those sections are consistent with the proposed actions for
this portion of section 110(a)(2)(J). Therefore, EPA proposes that
Wisconsin has met all of the infrastructure SIP requirements for PSD
associated with section 110(a)(2)(J) for the 1997 PM2.5,
1997 ozone, 2006 PM2.5, 2008 lead, 2008 ozone, 2010
NO2, 2010 SO2, and 2012 PM2.5 NAAQS.
III. What action is EPA taking?
EPA is proposing to approve revisions to Wisconsin's SIP that
implement the PM2.5 increment requirements and also
incorporates NOX as an ozone precursor. These revisions were
made to meet EPA's requirements for Wisconsin's PSD and NSR program and
are consistent with Federal regulations. Specifically, EPA is proposing
to approve the following:
(i) NR 404.05(2)(intro) and (am)
(ii) NR 404.05(3)(intro) and (am)
(iii) NR 404.05(4)(intro) and (am)
(iv) NR 405.02(3) and (21)(a)
(v) NR 405.02(21m)(a) and (c)
(vi) NR 405.02(22)(b)
(vii) NR 405.02(22m)(a)1. and 3., and (b)1.
(viii) NR 405.02(27)(a)6.
(ix) NR 405.07(8)(a)3m and 3m(Note)
(x) NR 405.07(8)(a)5.(Note)
The revisions pertaining to PM2.5 increment will fully
address the requirements of the PM2.5 PSD Increments, SILs,
and SMC Rule and the deficiencies identified in EPA's August 11, 2014,
Finding of Failure to Submit. The revisions pertaining to
NOX as a precursor to ozone will, in conjunction with EPA's
October 6, 2015 approval, address all of the PSD requirements of the
``Final Rule to Implement the 8-Hour Ozone National Ambient Air Quality
Standard--Phase 2''.
EPA is also proposing to approve the PSD related infrastructure
requirements found in CAA sections 110(a)(2)(C), (D)(i)(II), and (J)
for Wisconsin's 1997 PM2.5, 1997 ozone, 2006
PM2.5, 2008 lead, 2008 ozone, 2010 NO2, 2010
SO2, and 2012 PM2.5 NAAQS submittals.
IV. Incorporation by Reference
In this rule, EPA is proposing to include in a final EPA rule
regulatory text that includes incorporation by reference. In accordance
with requirements of 1 CFR 51.5, EPA is proposing to incorporate by
reference the WDNR rules regarding revisions to the PSD and NSR
programs discussed in section I of this preamble. EPA has made, and
will continue to make, these documents generally available through
www.regulations.gov, and/or at the National Archives and Records
Administration (NARA), and/or at the EPA Region 5 Office (please
contact the person identified in the FOR FURTHER INFORMATION CONTACT
section of this preamble for more information). For information on the
availability of this material at NARA, go to: www.archives.gov/federal-register/cfr/ibr-locations.html.
VI. Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the CAA and applicable
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in
reviewing SIP submissions, EPA's role is to approve state choices,
provided that they meet the criteria of the CAA. Accordingly, this
action merely 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 (Public Law 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).
