Air Plan Approval; Illinois; Nonattainment New Source Review
Requirements for the 2008 8-Hour Ozone Standard
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve, as a State Implementation Plan (SIP) revision, Illinois'
certification that its SIP satisfies the nonattainment new source
review (NNSR) requirements of the Clean Air Act (CAA) for the 2008
ozone National Ambient Air Quality Standard (NAAQS or Standard). Final
approval of the Illinois NNSR certification SIP will permanently stop
the Federal Implementation Plan (FIP) clocks triggered by EPA's
February 3 and December 11, 2017 findings that Illinois failed to
submit an NNSR plan for the Illinois portion of the Chicago-Naperville,
Illinois-Indiana-Wisconsin area (Chicago Nonattainment Area).

I. Background
A. 2008 8-Hour Ozone NAAQS
On March 12, 2008, EPA promulgated a revised 8-hour ozone NAAQS of
0.075 parts per million (ppm). See 73 FR 16436 (March 27, 2008). Upon
promulgation of a new or revised NAAQS, the CAA requires EPA to
designate as nonattainment any area that is violating the NAAQS based
on the three most recent years of ambient air quality data available at
the conclusion of the designation process. For ozone NAAQS, EPA must
also classify any nonattainment areas at the time of designation based
on the severity of their ozone levels (as determined based on the
area's ``design value'' \1\). See CAA sections 107(d)(1) and 181(a)(1)
and 77 FR 34225. The possible classifications are ``Marginal,''
``Moderate,'' ``Serious,'' ``Severe,'' and ``Extreme.'' Nonattainment
areas with a lower classification (such as marginal areas) have ozone
levels that are closer to meeting the standard than areas with a higher
classification (such as Extreme areas). See CAA section 181(a)(1).
---------------------------------------------------------------------------
\1\ Under 40 CFR 50.15, the ``design value'' for the 2008 8-hour
ozone NAAQS is the 3-year average of the annual fourth-highest daily
maximum 8-hour average ambient air quality ozone concentrations.
---------------------------------------------------------------------------
On March 6, 2015, EPA issued a final rule titled ``Implementation
of the 2008 National Ambient Air Quality Standards for Ozone: State
Implementation Plan Requirements'' (SIP Requirements Rule), which
detailed the requirements that state, tribal, and local air quality
management agencies must meet as they develop implementation plans for
areas where air quality exceeds the 2008 8-hour ozone NAAQS. See 80 FR
12264 (March 6, 2015).\2\ Areas that were designated as marginal ozone
nonattainment areas were required to attain the 2008 8-hour ozone NAAQS
no later than 36 months after the effective date of area designations
for the 2008 8-hour ozone NAAQS (i.e., July 20, 2015), based on 2012-
2014 monitoring data. See 40 CFR 51.1103.
---------------------------------------------------------------------------
\2\ The SIP Requirements Rule addresses a range of nonattainment
area SIP requirements for the 2008 8-hour ozone NAAQS, including
requirements pertaining to attainment demonstrations, reasonable
further progress (RFP), reasonably available control technology,
reasonably available control measures, major new source review,
emission inventories, and the timing of SIP submissions and of
compliance with emission control measures in the SIP. The rule also
revokes the 1997 ozone NAAQS and establishes anti-backsliding
requirements.
---------------------------------------------------------------------------
Areas designated nonattainment for the ozone NAAQS are subject to
the general nonattainment area planning requirements of CAA section 172
and also to the ozone-specific planning requirements of CAA section
182. States in the Ozone Transport Region (OTR) \3\ are additionally
subject to the requirements outlined in CAA section 184. Ozone
nonattainment areas in the lower classification levels have fewer and/
or less stringent mandatory air quality planning and control
requirements than those in higher classifications. For a marginal area,
a state is required to submit a baseline emissions inventory, adopt a
SIP requiring emissions statements from stationary sources, and
implement a NNSR program for the relevant ozone standard. See CAA
section 182(a). For each higher ozone nonattainment
[[Page 50552]]
classification, a state must comply with all lower area classification
requirements, plus additional emissions controls and more expansive
NNSR offset requirements. For example, the state must comply with all
marginal area classification requirements plus it must submit SIP
revisions to: (1) Provide for reductions of emissions of volatile
organic compounds (VOC) and nitrogen oxides (NOX) of at
least 15 percent from baseline emissions over 6 years; (2) require the
implementation of reasonably available control technology (RACT); (3)
provide for a vehicle emissions inspection and maintenance (I/M)
program; (4) include contingency measures for failure to attain; and
(5) include stage II gasoline vapor recovery requirements. See 42
U.S.C. 7511a(b) and 7502.
---------------------------------------------------------------------------
\3\ The OTR is comprised of the following states: Connecticut,
Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey,
New York, Pennsylvania, Rhode Island, Vermont, and the Consolidated
Metropolitan Statistical Area that includes the District of
Columbia. 42 U.S.C. 7511c(a). States in the OTR are required to
submit SIP revisions addressing reasonably available control
technology (RACT) requirements for the pollutants that form ozone,
even if the areas in the state meet the ozone standards.
---------------------------------------------------------------------------
EPA classified the Chicago-Naperville, Illinois-Indiana-Wisconsin
area (Chicago Nonattainment Area) as a marginal nonattainment area for
the 2008 8-hour ozone NAAQS on June 11, 2012 (effective July 20, 2012)
using certified ambient air quality monitoring data from calendar years
2009-2011. See 77 FR 34221. The Chicago area includes Cook, DuPage,
Kane, Lake, McHenry, and Will Counties and parts of Grundy and Kendall
Counties in Illinois; Lake and Porter Counties in Indiana; and part of
Kenosha County in Wisconsin.
On May 4, 2016, pursuant to section 181(b)(2) of the CAA, EPA
determined that the Chicago area failed to attain the 2008 8-hour ozone
NAAQS by the July 20, 2015, marginal area attainment deadline and did
not meet the CAA section 181(a)(5) criteria, as interpreted in 40 CFR
51.1107, for a 1-year attainment date extension. See 81 FR 26697 (May
4, 2016). Thus, EPA reclassified this area by operation of law as
moderate for the 2008 ozone NAAQS. Id.\4\ In that action, EPA
established January 1, 2017, as the due date for the state to submit
all moderate area nonattainment plan SIP requirements applicable to
newly reclassified areas.
---------------------------------------------------------------------------
\4\ The Metro-East area also did not attain the 2008 8-hour
ozone NAAQS by July 20, 2015; however, EPA found this area to be
eligible for a 1-year attainment date extension, for a new
attainment date of July 20, 2016. See 81 FR 26697 (May 4, 2016).
---------------------------------------------------------------------------
As explained in the SIP Requirements Rule, Illinois was required to
develop a SIP revision addressing NNSR requirements for its marginal
ozone nonattainment areas by July 20, 2015. See 80 FR 12266 (March 6,
2015). Additionally, because the Chicago area was reclassified to
moderate nonattainment, Illinois was required to submit a moderate area
NNSR SIP by January 1, 2017. See 81 FR 26697 (May 4, 2016).\5\ NNSR is
a preconstruction review permit program that applies to new major
stationary sources or major modifications at existing sources located
in a nonattainment area. See CAA sections 172(c)(5), 173 and 182. The
specific NNSR requirements for the 2008 8-hour ozone NAAQS are located
in 40 CFR 51.160-165.
---------------------------------------------------------------------------
\5\ Illinois' obligation to submit the NNSR SIP was not affected
by the D.C. Circuit Court's February 16, 2018 decision on portions
of the SIP Requirements Rule in South Coast Air Quality Mgmt. Dist.
v. EPA, No. 15-1115, 2018 U.S. App. LEXIS 3636 (DC Cir. Feb. 16,
2018).
---------------------------------------------------------------------------
B. 2017 Findings of Failure To Submit SIPs for the 2008 8-Hour Ozone
NAAQS
On February 3, 2017, EPA found that 15 states and the District of
Columbia failed to submit SIP revisions to satisfy certain
nonattainment plan requirements for the 2008 ozone NAAQS. See 82 FR
9158. EPA found, inter alia, that Illinois failed to timely submit a
SIP revision to satisfy NNSR requirements for the Chicago and Metro-
East \6\ ozone nonattainment areas. In addition, on December 11, 2017,
EPA found, inter alia, that Illinois failed to timely submit a revision
to its SIP to satisfy moderate NNSR requirements for the Chicago area.
See 82 FR 58118.
---------------------------------------------------------------------------
\6\ The Metro-East area includes the Illinois portion of the St.
Louis-St. Charles-Farmington, Missouri-Illinois ozone nonattainment
area, which includes Madison, Monroe and St. Clair Counties in
Illinois, and Franklin, Jefferson, St. Charles, and St. Louis
Counties and the City of St. Louis in Missouri.
---------------------------------------------------------------------------
These findings established certain deadlines for the imposition of
sanctions if a state does not submit a timely SIP revision addressing
the requirements for which EPA made the findings and the requirement
for EPA to promulgate a FIP to address any outstanding SIP
requirements. Specifically, Illinois was required to submit a complete
SIP addressing the deficiencies that were the basis for each finding
within 18 months of the effective dates of the findings (i.e.,
September 6, 2018 and July 10, 2019, respectively) so as to avoid
triggering, pursuant to CAA section 179(a) and (b) and 40 CFR 52.31,
the offset sanction identified in CAA section 179(b)(2) in the affected
nonattainment area. Additionally, these rules triggered the requirement
for EPA to promulgate a FIP for the affected nonattainment area if EPA
does not take final action to approve the state's submittal within 2
years of the effective date of the findings (i.e., March 6, 2019, and
January 10, 2020, respectively).
On March 1, 2018, EPA redesignated the Metro-East area to
attainment for the 2008 8-hour ozone NAAQS because EPA found this area
to have met the statutory requirements for redesignation to attainment
under the CAA. See 83 FR 8756 (March 1, 2018). In that action, EPA also
approved, as a revision to the Illinois SIP, Illinois' plan for
maintaining the 2008 ozone NAAQS through calendar year 2030 in the
Metro-East area. NNSR SIP revisions are no longer required if an area
is redesignated to attainment; the CAA's Prevention of Significant
Deterioration (PSD) program requirements apply in lieu of NNSR. See 82
FR 9160. Therefore, the finding of failure to submit no longer applies
to areas that have been redesignated to attainment. Because the Metro-
East area is now designated attainment, a NNSR SIP is not required for
this area.
On May 23, 2018, the Illinois Environmental Protection Agency
(IEPA) submitted a SIP revision addressing the NNSR requirements of the
CAA for areas designated as nonattainment for the 2008 ozone NAAQS. On
July 12, 2018, EPA found that Illinois' NNSR SIP submission fulfilled
the completeness criteria in 40 CFR part 51, appendix V.\7\ Through the
completeness finding, EPA determined that the deficiencies which formed
the basis for the February 3, 2017 and December 11, 2017 findings had
been corrected and, as a result, the sanctions clock was permanently
stopped. Final approval of Illinois' May 23, 2018 NNSR SIP revision
would permanently stop the FIP clocks triggered by the February 3, 2017
and December 11, 2017 findings.

II. Summary of the State's Submittal
On May 23, 2018, IEPA submitted a SIP revision requesting EPA's
approval of Illinois' certification that its existing SIP-approved NNSR
regulations fully satisfy the NNSR requirements set forth in 40 CFR
51.165 for both marginal and moderate ozone nonattainment areas for the
2008 ozone NAAQS. IEPA indicates that its NNSR SIP submission is
intended to respond to the February 3 and December 11, 2017 findings
for the Chicago and Metro-East areas. Specifically, Illinois is
certifying that its existing NNSR program covering its ozone
nonattainment areas for the 2008 8-hour ozone NAAQS, including the
Chicago Nonattainment Area, contains the NNSR elements required by 40
CFR 51.165, as amended by the SIP Requirements Rule, for ozone and its
precursors.
Illinois' submittal includes a document titled, ``Illinois'
Compliance
[[Page 50553]]
With Nonattainment New Source Review Requirements For The 2008 Ozone
Standard'' (NNSR checklist), which contains Illinois' detailed
assessment of how its SIP-approved NNSR regulations address each of the
NNSR requirements for the 2008 ozone NAAQS as codified at 40 CFR
51.165. Illinois certifies that it already complies with CAA sections
172(c)(5) and 182(a)(2)(C), which require states that have been
designated nonattainment for an ozone NAAQS to submit plans or plan
revisions containing certain required elements, including permit
programs for the construction and operation of new or modified
stationary sources in the nonattainment area. Specifically, Illinois
has certified that its existing State regulations in Title 35 of
Illinois Administrative Code Part 203 (35 IAC Part 203) fully satisfy
the NNSR requirements set forth in 40 CFR 51.165 for both marginal and
moderate ozone nonattainment areas because they contain all NNSR SIP
elements required by 40 CFR 51.165 for its ozone nonattainment areas.
EPA proposes to find that Illinois' submittal addresses the State's
obligations as described in the February 3 and December 11, 2017
findings.
III. What is EPA's analysis?
The minimum SIP requirements for NNSR permitting programs for the
2008 8-hour ozone NAAQS are located in 40 CFR 51.165. See 40 CFR
51.1114. These NNSR program requirements include those promulgated in
the ``Phase 2 Rule'' implementing the 1997 8-hour ozone NAAQS (75 FR
71018, November 29, 2005) and the SIP Requirements Rule implementing
the 2008 8-hour ozone NAAQS. Under the Phase 2 Rule, the SIP for each
ozone nonattainment area must contain NNSR provisions that: Set major
source thresholds for NOX and VOC pursuant to 40 CFR
51.165(a)(1)(iv)(A)(1)(i)-(iv) and (2); classify physical changes as a
major source if the change would constitute a major source by itself
pursuant to 40 CFR 51.165(a)(1)(iv)(A)(3); consider any significant net
emissions increase of NOX as a significant net emissions
increase for ozone pursuant to 40 CFR 51.165(a)(1)(v)(E); consider
certain increases of VOC emissions in extreme ozone nonattainment areas
as a significant net emissions increase and a major modification for
ozone pursuant to 40 CFR 51.165(a)(1)(v)(F); set significant emissions
rates for VOC and NOx as ozone precursors pursuant to 40 CFR
51.165(a)(1)(x)(A)-(C) and (E); contain provisions for emissions
reductions credits pursuant to 40 CFR 51.165(a)(3)(ii)(C)(1)-(2);
provide that the requirements applicable to VOC also apply to
NOX pursuant to 40 CFR 51.165(a)(8); and set offset ratios
for VOC and NOX pursuant to 40 CFR 51.165(a)(9)(i)-(iii)
(renumbered as (a)(9)(ii)-(iv) under the SIP Requirements Rule for the
2008 8-hour ozone NAAQS). Under the SIP Requirements Rule for the 2008
8-hour ozone NAAQS, the SIP for each ozone nonattainment area
designated nonattainment for the 2008 8-hour ozone NAAQS and designated
nonattainment for the 1997 ozone NAAQS on April 6, 2015, must also
contain NNSR provisions that include the anti-backsliding requirements
at 40 CFR 51.1105. See 40 CFR 51.165(a)(12).
Illinois' NNSR rules, as set forth in 35 IAC Part 203, Major
Stationary Sources Construction And Modification, are designed to
ensure that the construction of a major new source of air pollution or
a large increase of emissions at an existing source does not interfere
with the attainment demonstration and does not delay timely achievement
of the ambient air quality standards. The rules require owners or
operators of major projects to: (1) Apply the Lowest Achievable
Emission Rate (LAER) or, for certain existing sources, the Best
Available Control Technology (BACT) on emissions of the nonattainment
pollutant from the major project; (2) offset the emissions of the
nonattainment pollutant from a major project by emission reductions
from other sources in the nonattainment area; (3) demonstrate that
other sources in the State which are under common ownership or control
with the person proposing the project are in compliance with the CAA;
and (4) analyze alternatives to the particular project to determine
whether the benefits of the project outweigh the environmental and
social costs.
EPA last approved revisions to Illinois' NNSR SIP on May 13, 2003.
See 68 FR 25504 (May 13, 2003).\8\ In that action, EPA approved
amendments to 35 IAC 203 to better track the language of CAA sections
182(c)(6), (7), and (8). See 68 FR 25505. The changes dealt with how
one determines whether a proposed change at a source is a major
modification.
---------------------------------------------------------------------------
\8\ For other relevant approvals, see 45 FR 11470 (February 21,
1980); 46 FR 44172 (September 3, 1981); 50 FR 38803 (September 25,
1985); 51 FR 10837 (March 31, 1986); 57 FR 59928 (December 17,1992);
and 60 FR 49778 (September 27, 1995).
---------------------------------------------------------------------------
Based on our review of the NNSR checklist that Illinois
incorporated into the SIP submittal, and the version of 35 IAC 203
approved into the Illinois SIP, we propose to find that Illinois' SIP-
approved NNSR program at 35 IAC 203 contains the minimum required NNSR
elements as specified in 40 CFR 51.165 for Illinois' ozone
nonattainment areas. We are proposing to approve Illinois'
certification that 35 IAC 203 is consistent with 40 CFR 51.165 and
meets the requirements of CAA sections 172(c)(5), 173, 110(a)(2),
182(a)(4) and 182(b)(5) under the 2008 ozone standard for the Illinois
portion of the Chicago Ozone Nonattainment Area. Final approval of
Illinois' NNSR certification would address the deficiencies that were
the basis for the February 3 and December 11, 2017 findings, and would
turn off the FIP clock for the Illinois portion of the Chicago
Nonattainment Area. While some of Illinois' regulations are worded or
organized differently than the Federal counterparts, EPA proposes to
find that these differences do not affect the relative stringency of
such provisions.
The following table lists the specific provisions of Illinois' NNSR
rules that address the required elements of the Federal NNSR rules:

A. Major Source Thresholds for Ozone--40 CFR 51.165(a)(1)(iv)(A)(1)(i)-
(iv) and (2)
The major source thresholds for both VOC and NOX (i.e.,
ozone precursors) are defined in 40 CFR 51.165(a)(1)(iv)(A)(1)(i)-(iv)
and (2). The applicable thresholds vary depending on the classification
of the ozone nonattainment area. For marginal and moderate ozone
nonattainment areas, a major stationary source of ozone is a source
that emits, or has the potential to emit, 100 tons per year or more of
VOC or NOX. Different emissions thresholds apply for
Serious, Severe, and Extreme ozone nonattainment areas and for areas
located in an OTR.
Illinois has certified that the Federal requirements for major
source thresholds for VOC and NOX are addressed by 35 IAC
203.206(b). Under 35 IAC 203.206(b), for an area designated as
nonattainment for ozone, a major stationary source is a stationary
source which emits or has the potential to emit VOC \9\ or
NOX in an amount equal to or greater than (1) 100 tons per
year in an area classified as marginal or moderate nonattainment for
ozone; (2) 50 tons per year in an area classified as serious
nonattainment for ozone; (3) 25 tons per year in an area classified as
severe nonattainment for ozone; and (4) 10 tons per year in an area
classified as extreme nonattainment for ozone. Illinois' thresholds are
consistent with the Federal thresholds; therefore, we propose to find
that Illinois' NNSR provisions at 35 IAC 203.206(b) satisfy the
requirements of 40 CFR 51.165(a)(1)(iv)(A)(1)(i)-(iv) and (2).
---------------------------------------------------------------------------
\9\ The Illinois SIP also refers to VOC as volatile organic
material (VOM). See 35 IAC 211.7150.
---------------------------------------------------------------------------
B. Change Constitutes Major Source by Itself--40 CFR
51.165(a)(1)(iv)(A)(3)
Under 40 CFR 51.165(a)(1)(iv)(A)(3), any physical change that would
occur at a stationary source not qualifying as a major stationary
source becomes a major stationary source, if the change would
constitute a major stationary source by itself. Illinois has certified
that this requirement is addressed by 35 IAC 203.206(c), which provides
that any physical change that occurs at a stationary source which does
not qualify as a major stationary source will be considered a major
stationary source, if the change would constitute a major stationary
source by itself. Illinois' provisions at 35 IAC 203.206(c) for what
constitutes a major source are consistent with the Federal provisions
at 40 CFR 51.165(a)(1)(iv)(A)(3); therefore, we propose to find that
the Illinois SIP at 35 IAC 203.206(c) satisfies the requirements of 40
CFR 51.165(a)(1)(iv)(A)(3).
C. Significant Net Emissions Increase of NOX is Significant
for Ozone--40 CFR 51.165(a)(1)(v)(E)
Under 40 CFR 51.165(a)(1)(v)(E), any significant net emissions
increase of NOX is considered significant for ozone.
Illinois has certified that this requirement is addressed by 35 IAC
203.207(b), which provides that any net emissions increase that is
significant for VOC or NOX shall be considered significant
for ozone. Illinois' provisions at 35 IAC 203.207(b) are consistent
with the Federal requirements at 40 CFR 51.165(a)(1)(v)(E); therefore,
we propose to find that 35 IAC 203.207(b) satisfies the requirements of
40 CFR 51.165(a)(1)(v)(E).
D. Any Emissions Change of VOC in an Extreme Area Triggers NNSR--40 CFR
51.165(a)(1)(v)(F)
Under 40 CFR 51.165(a)(1)(v)(F), any physical change in, or change
in the method of operation of, a major stationary source of VOC that
results in any increase in emissions of VOC from any discrete
operation, emissions unit, or other pollutant emitting activity at the
source shall be considered a significant net emissions increase and a
major modification for ozone, if the major stationary source is located
in an extreme ozone nonattainment area that is subject to CAA title 1,
part D subpart 2. Illinois has certified that this requirement is
addressed by 35 IAC 203.207(f). That provision states that in areas
classified as extreme nonattainment for ozone, beginning on the date
that EPA classifies an area as an extreme nonattainment area for ozone,
any physical change in or change in the method of operation of a major
stationary source which results in any increase in emissions of VOC or
NOX from a discrete operation, unit, or other pollutant
emitting activity shall be considered a major modification. Illinois'
provisions at 35 IAC 203.207(f) are consistent with the Federal
requirements at 40 CFR 51.165(a)(1)(v)(F); therefore, we propose to
find that 35 IAC 203.207(f) satisfies the requirements of 40 CFR
51.165(a)(1)(v)(F).
E. Significant Emissions Rates for VOC and NOX as Ozone
Precursors--40 CFR 51.165(a)(1)(x)(A)-(C) and (E)
Under 40 CFR 51.165(a)(1)(x)(A), (B) and (C), the significant
emission rate for ozone is defined as 40 tons per year of VOC or
NOX, except that the significant emission rate in serious or
extreme nonattainment areas shall be 25 tons per year. Under 40 CFR
51.165(a)(1)(x)(E), any increase in actual emissions of VOC from any
emissions unit at a major stationary source of VOC located in an
extreme ozone nonattainment area shall be considered a significant net
emissions increase. Illinois has certified that it satisfies these
requirements pursuant to 35 IAC 203.207(d), (e) and (f), and 35 IAC
203.209(a) and (b). Specifically, 35 IAC 203.207(d) and (e), and 35 IAC
203.209(a) and (b) establish the significant emission rate for ozone as
40 tons per year of VOC or NOX and 25 tons per year in
serious or extreme nonattainment areas. Additionally, 35 IAC 203.207(f)
specifies that in areas classified as extreme nonattainment for ozone,
any physical change in or change in the method of operation of a major
stationary source which results in any increase in emissions of VOC or
NOX from a discrete operation, unit, or other pollutant
emitting activity shall be considered a major modification. Because the
Illinois SIP's provisions at 35 IAC 203.207(d), (e) and (f), and 35 IAC
203.209(a) and (b) are consistent with the Federal requirements at 40
CFR 51.165(a)(1)(x)(A)-(C) and (E), we propose to find that the above
Illinois SIP provisions satisfy the requirements of 40 CFR
51.165(a)(1)(x)(A)-(C) and (E).
F. Provisions for Emissions Reduction Credits--40 CFR
51.165(a)(3)(ii)(C)(1) and (2)
Under 40 CFR 51.165(a)(3)(ii)(C)(1) and (2), to be considered
creditable, emission reductions achieved by shutting down an existing
emission unit or curtailing production or operating hours must be
surplus, permanent, quantifiable, and federally enforceable. Shutdowns
or curtailments must have occurred after the last day of the base year
for the SIP planning process. Reviewing authorities may choose to
consider a prior shutdown or curtailment to have occurred after the
last day of the base year if the projected emissions inventory used to
develop the attainment demonstration explicitly includes emissions from
the previously shut down or curtailed emissions units, but in no event
may credit be granted for shutdowns that occurred prior to August 7,
1977. Shutdown or curtailment reductions occurring before the last day
of the base year for the SIP planning process may also be generally
credited if the shutdown or curtailment occurred on or after the date
the construction permit application is filed or if the applicant can
establish that the proposed new emissions unit is a replacement for the
shutdown or curtailed emission unit and the emission reductions that
result are
[[Page 50555]]
surplus, permanent, quantifiable, and federally enforceable.
Illinois certifies that these requirements are satisfied by 35 IAC
203.302(a), 35 IAC 203.303(b) and (f), 35 IAC 203.602 and 35 IAC
203.701. In particular, 35 IAC 203.302(a) establishes a general
obligation that ``the owner or operator of a new major source or major
modification shall provide emission offsets equal to or greater than
the allowable emissions from the source or the net increase in
emissions from the modification sufficient to allow [IEPA] to determine
that the source or modification will not interfere with reasonable
further progress [RFP] . . . '' With respect to 40 CFR
51.165(a)(3)(ii)(C)(1)(i), the Illinois SIP at 35 IAC 203.303(b) and 35
IAC 203.701 requires that all emission offsets must: (1) Be of the same
pollutant and of a type with approximately the same qualitative
significance for public health and welfare as that attributed to the
increase from a particular change; (2) be federally enforceable by
permit; (3) not have been previously relied on in issuing any permit
pursuant to the Illinois SIP for demonstrating attainment or RFP; and
(4) be maintained permanently. Further, 35 IAC 203.303(b)(3) restricts
the use of emission reductions from past shutdowns or curtailments, and
requires the proposed new or modified source to be a replacement for
the shutdown or curtailment. Additionally, under 35 IAC 203.602, no
person shall cause or allow the operation of a new major stationary
source or major modification where the owner or operator has
demonstrated that it would not interfere with RFP by providing emission
offsets pursuant to 35 IAC 203.302 without maintaining those emission
offsets or other equivalent offsets.\10\
---------------------------------------------------------------------------
\10\ Illinois has explained that the phrase ``other equivalent
offsets'' as used in 35 IAC 203.602, coupled with the language in 35
IAC 203.701, establishes that emission offsets must be permanent,
and that if emission reductions relied upon by a source cease to be
viable as offsets for some reason, the source would need to obtain
equivalent offsets.
---------------------------------------------------------------------------
With respect to 40 CFR 51.165(a)(3)(ii)(C)(2), we note that
Illinois' language in 35 IAC 203.303(b)(3) does not explicitly require
that shutdowns or curtailments occur on or after the date a permit
application was filed, as specified in 40 CFR 51.165(a)(3)(ii)(C)(2).
However, Illinois satisfies the Federal requirements by limiting in 35
IAC 203.303(b)(3) the circumstances under which prior shutdowns or
curtailments can be credited as offsets. For example, given an
applicant for a NNSR permit must provide emission offsets under 35 IAC
203.302, the meaning of the phrase ``past shutdown'' as used in 35 IAC
203.303(b)(3) is consistent with the wording of 40 CFR
51.165(a)(3)(ii)(C)(2)(i) as it establishes additional requirements for
offsets that occurred prior to the filing of the application. Because
35 IAC 203.302(a), 35 IAC 203.303(b) and (f), 35 IAC 203.602 and 35 IAC
203.701 address all of the elements required by 40 CFR
51.165(a)(3)(ii)(C)(1) and (2), we propose to find that the Illinois
SIP satisfies the requirements of 40 CFR 51.165(a)(3)(ii)(C)(1) and
(2).
G. Requirements for VOC Apply to NOX as Ozone Precursors--40
CFR 51.165(a)(8)
Under 40 CFR 51.165(a)(8), all requirements applicable to major
stationary sources and major modifications of VOC shall apply to
NOX except where the Administrator has granted a
NOX waiver applying the standards set forth under CAA
section 182(f) and the waiver continues to apply. Illinois certifies
that these Federal requirements are satisfied by 35 IAC 203.206(b)
(major stationary source); 35 IAC 203.207(b), (d), (e) and (f) (major
modification of a source); 35 IAC 203.209(a) and (b) (significant
emissions determination); 35 IAC 203.301(e) and (f) (LAER); and 35 IAC
203.302 (maintenance of RFP and emission offsets). As already
discussed, we have reviewed 35 IAC 203.206(b); 35 IAC 203.207(b), (d),
(e) and (f); 35 IAC 203.209(a) and (b); and 35 IAC 203.302 and find
that these provisions contain language that is consistent with the
corresponding Federal NNSR requirements with respect to the treatment
of VOC and NOX in ozone nonattainment areas. The Federal
requirements for LAER are also addressed by 35 IAC 203.301(e) and (f),
which establish specific LAER and BACT requirements for existing
sources located in serious or severe ozone nonattainment areas. Because
35 IAC 203.206(b), 35 IAC 203.207(b), (d), (e) and (f), 35 IAC
203.209(a) and (b), 35 IAC 203.301(e) and (f), and 35 IAC 203.302
contain language that is consistent with the Federal requirements, we
propose to find that the Illinois SIP satisfies the requirements of 40
CFR 51.165(a)(8).
H. Offset Ratios for VOC and NOX for Ozone Nonattainment
Areas--40 CFR 51.165(a)(9)(ii), (iv)
Under 40 CFR 51.165(a)(9)(ii)(A)-(E), the VOC offset ratios shall
be 1.1:1 in marginal ozone nonattainment areas, 1.15:1 in moderate
ozone nonattainment areas, 1.2:1 in serious ozone nonattainment areas,
1.3:1 in severe ozone nonattainment areas, and 1.3:1 in severe ozone
nonattainment areas. Illinois certifies that these requirements are
satisfied by 35 IAC 203.302(a). Specifically, 35 IAC 203.302(a)(1)
requires offset ratios for both VOC and NOX that are
consistent with 40 CFR 51.165(a)(9)(ii)(A)-(E). Therefore, we propose
to find that the Illinois SIP at 35 IAC 203.302(a) satisfies the
requirements of 40 CFR 51.165(a)(9)(ii)(A)-(E).
For ozone nonattainment areas subject to CAA title 1, part D,
subpart 1 but not subpart 2, 40 CFR 51.165(a)(9)(iv) requires an offset
ratio of at least 1:1. Because all of the current ozone nonattainment
areas in Illinois were designated under CAA title 1, part D, subpart 2,
40 CFR 51.165(a)(9)(iv) does not apply to Illinois at this time.
I. OTR Requirements
Illinois' approved SIP does not contain the OTR provisions set
forth in 40 CFR 51.165(a)(1)(iv)(A)(1)(ii), 40 CFR
51.165(a)(1)(iv)(A)(2)(ii), 40 CFR 51.165(a)(1)(v)(E), 40 CFR
51.165(a)(1)(x)(C), 40 CFR 51.165(a)(8), and 40 CFR 51.165(a)(9)(iii)
because Illinois is not located in an OTR. Illinois is not required to
include these requirements in its SIP until such time as EPA publishes
rules that establish Illinois as a part of the OTR.
J. Anti-backsliding Provisions for the Revoked 1997 NAAQS--40 CFR
51.165(a)(12)
``Anti-backsliding'' provisions are designed to ensure that for
existing ozone nonattainment areas that are designated nonattainment
for a revised and more stringent ozone NAAQS, (1) there is protection
against degradation of air quality (i.e., the areas do not
``backslide''), (2) the areas continue to make progress toward
attainment of the new, more stringent NAAQS, and (3) there is
consistency with the ozone NAAQS implementation framework outlined in
CAA title 1, part D, subpart 2. See 78 FR 34211. As part of the SIP
Requirements Rule, EPA revoked the 1997 NAAQS for all purposes and
established anti-backsliding requirements for areas that remained
designated nonattainment for the revoked NAAQS. See 80 FR 12265 and 40
CFR 51.165(a)(12). Under 40 CFR 51.165(a)(12), the anti-backsliding
requirements at 40 CFR 51.1105 apply in any area designated
nonattainment for the 2008 ozone NAAQS and designated nonattainment for
the 1997 ozone NAAQS on April 6, 2015. Illinois has certified that
there were no areas
[[Page 50556]]
designated as nonattainment for the 1997 8-hour ozone NAAQS on April 6,
2015.
Attainment status designations for Illinois are found at 40 CFR
81.314. With respect to the 1997 8-hour ozone NAAQS, all areas in
Illinois attained the 1997 8-hour ozone NAAQS prior to April 6, 2015.
See 77 FR 25363 (April 30, 2012) and 77 FR 48062 (August 13, 2012).
Since all areas in Illinois were designated as attainment or
unclassifiable/attainment on April 6, 2015 for the 1997 8-hour ozone
NAAQS, the anti-backsliding requirements of 40 CFR 51.165(a)(12) do not
apply for the 2008 8-hour ozone NAAQS. Accordingly, Illinois' approved
SIP does not contain the anti-backsliding provisions set forth in 40
CFR 51.165(a)(12).
IV. Proposed Action
EPA is proposing to approve Illinois' May 23, 2018 SIP revision
addressing the NNSR requirements for the 2008 ozone NAAQS for the
Chicago Nonattainment Area. EPA has concluded that Illinois' submission
fulfills the 40 CFR 51.1114 revision requirement, meets the
requirements of CAA sections 110 and 172 and the minimum SIP
requirements of 40 CFR 51.165, as well as its obligations under EPA's
February 3 and December 11, 2017 findings.
V. 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 (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).
The proposed rule approving Illinois' 2008 8-hour ozone NAAQS NNSR
SIP revision 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).
