Air Plan Approval; Illinois; Prevention of Significant
Deterioration

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is approving
revisions to the Illinois State Implementation Plan (SIP) that were
submitted by the Illinois Environmental Protection Agency (IEPA) on
September 22, 2020, and amended on November 5, 2020, and March 3, 2021.
These revisions implement new preconstruction permitting regulations
for certain new or modified sources of air pollution in attainment and
unclassifiable areas under the Prevention of Significant Deterioration
(PSD) program of the Clean Air Act (CAA). EPA is also transferring to
IEPA responsibility for administering existing PSD permits that EPA
previously issued to sources in Illinois, and for processing any PSD
permit actions related to such permits.

DATES: This final rule is effective on October 12, 2021.

ADDRESSES: EPA has established dockets for this action under Docket ID
Nos. EPA-R05-OAR-2020-0501, EPA-R05-OAR-2020-0502, and EPA-R05-OAR-

I. Background

    Section 110(a)(2)(C) of the CAA requires that each SIP include a
program to provide for the regulation of the construction and
modification of stationary sources within the areas covered by the SIP.
We refer to these as the New Source Review (NSR) provisions. They
consist primarily of: (1) A permit program as required by part C of
subsection I of the CAA, PSD, as necessary to assure that national
ambient air quality standards (NAAQS) are achieved; (2) a permit
program as required by part D of subsection I of the CAA, Plan
Requirements for Nonattainment Areas, as necessary to assure that NAAQS
are attained and maintained in ``nonattainment areas'' (known as
``nonattainment NSR''), and (3) a permit program for minor sources and
minor modifications of major sources as required by section
110(a)(2)(C) of the CAA. Specific plan requirements for an approvable
PSD SIP are provided in sections 160-169 of the CAA and the
implementing regulations at 40 CFR 51.166. The requirements applicable
to SIP requirements for nonattainment areas are provided in sections
171-193 of the CAA and the implementing regulations at 40 CFR 51.165.
The Federal PSD requirements at 40 CFR 52.21 apply through Federal
Implementation Plans (FIPs) in states without a SIP-approved PSD
program.
    The PSD SIP requirements apply to new major sources or major
modifications at existing major stationary sources for pollutants where
the area the source is located has been designated as ``attainment'' or
``unclassifiable'' with respect to the NAAQS under section 107(d) of
the CAA. Under section 160 of the CAA, the purposes of the PSD program
are to: (1) Protect public health and welfare; (2) preserve, protect
and enhance the air quality in national parks, national wilderness
areas, national monuments, national seashores, and other areas of
special national or regional natural, recreational, scenic, or historic
value; (3) ensure that economic growth will occur in a manner
consistent with the preservation of existing clean air resources; (4)
assure that emissions from any source in any State will not interfere
with any portion of the applicable implementation plan to prevent
significant deterioration of air quality for any other State; and (5)
assure that any decision to permit increased air pollution in any area
to which the PSD program applies is made only after careful evaluation
of all the consequences of such a decision and after adequate
procedural opportunities for informed public participation in the
decision making process.
    Before a PSD permit can be issued, the stationary source must
demonstrate that the new major source or major modification will be
equipped with the Best Available Control Technology (BACT) for all
po11utants regulated under the PSD program that are emitted in
significant amounts, and that increased emissions from the project will
not result in a violation of the NAAQS or applicable ambient air
quality increments. See CAA section 165.
    Because Illinois does not currently have a SIP-approved PSD
program, PSD permits in Illinois have been issued under a FIP
incorporating the requirements of 40 CFR 52.21. Prior to April 7, 1980,
EPA was solely responsible for, and operated, the PSD permitting
program in Illinois. However, since April 7, 1980, IEPA has issued PSD
permits under a delegation agreement with EPA that authorizes IEPA to
implement the FIP. See 46 FR 9580 (Jan. 29, 1981) (1980 Delegation
Agreement). Under a November 16, 1981 amendment to the 1980 Delegation
Agreement,\1\ IEPA also has the authority to amend or revise any PSD
permit issued by EPA under the FIP. Thus, all PSD permits issued in
Illinois are currently considered Federal permits; and PSD permits
issued after April 7, 1980, are enforceable by Illinois and EPA since
they were issued under both Illinois and EPA authority.
---------------------------------------------------------------------------

    \1\ A copy of this amendment to the delegation agreement is
available in the docket for this action.
---------------------------------------------------------------------------

    On September 22, 2020, IEPA submitted to EPA a request to revise
the Illinois SIP to establish a SIP-approved PSD program in Illinois.
Specifically, IEPA requested that EPA incorporate

into the SIP the following: (1) Amendments to Title 35 Illinois
Administrative Code (35 Ill. Adm. Code) Part 203, Major Stationary
Source Construction and Modification; (2) new regulations at 35 Ill.
Adm. Code Part 204, Prevention of Significant Deterioration; (3)
amendments to 35 Ill. Adm. Code Part 211, Definitions and General
Provisions; \2\ and (4) amendments to 35 Ill. Adm. Code Part 252,
Public Participation in the Air Pollution Control Permit Program. The
amendments to 35 Ill. Adm. Code Parts 203 and 211 update these rules to
refer to permitting pursuant to 35 Ill. Adm. Code Part 204, as well as
to 40 CFR 52.21. These amendments to 35 Ill. Adm. Code Parts 203 and
211 involve regulations that EPA has previously approved into the
Illinois SIP for purposes of other provisions of the CAA (excluding the
PSD program). See 40 CFR 52.720(c). On November 5, 2020, IEPA submitted
additional information clarifying how it intends to implement specific
provisions identified by EPA, and how it plans to correct any
typographical errors or omissions that EPA identified in its October
22, 2020 review of IEPA's September 2020 submittal. Additionally, on
March 3, 2021, IEPA submitted a request to withdraw a portion of the
submitted amendments, 35 Ill. Adm. Code 252.301, from approval into the
SIP. This provision applies to EPA's review of title V permits issued
by IEPA.
---------------------------------------------------------------------------

    \2\ IEPA's September 2020 submittal also addressed Illinois'
Infrastructure SIP requirements under sections 110(a)(2)(C),
110(a)(2)(D)(i)(II), 110(a)(2)(D)(ii), and 110(a)(2)(J) of the CAA
for all of the following NAAQS: 2008 lead, 2010 nitrogen dioxide,
1997 ozone, 2008 ozone, 2015 ozone, 1997 particulate matter with
aerodynamic diameter less than 2.5 microns (PM2.5), 2006
PM2.5, 2012 PM2.5, and 2010 sulfur dioxide.
This action does not address the infrastructure SIP portion of
IEPA's submittal. EPA plans to address those requirements in a
separate action.
---------------------------------------------------------------------------

    On April 28, 2021, EPA issued a notice of proposed rulemaking
(proposed rule) in which we proposed to find that IEPA's proposed
regulations and amendments meet the requirements of sections 160-169 of
the CAA and the implementing regulations at 40 CFR 51.166. See 86 FR
22372. We explained in the preamble to the proposed rule that, with a
few exceptions, IEPA's PSD regulations at 35 Ill. Adm. Code Part 204
and 35 Ill. Adm. Code Part 252 largely mirror the Federal regulations
at 40 CFR 52.21 and 40 CFR part 124, respectively. We proposed to
approve IEPA's PSD regulations contained in 35 Ill. Adm. Code Parts 204
and 252 to apply statewide, except in Indian reservations. For the
facilities in Indian reservations in the State, and any other area
where EPA or an Indian tribe has demonstrated that a tribe has
jurisdiction, the PSD FIP incorporating 40 CFR 52.21 would continue to
apply and EPA would retain responsibility for issuing permits affecting
such sources.
    In this final action, EPA finds that IEPA's regulations at 35 Ill.
Adm. Code Part 204 and the amendments to 35 Ill. Adm. Code Parts 203,
211 and 252 meet the requirements of sections 160-169 of the CAA and
the minimum program requirements of 40 CFR 51.166. EPA is therefore
approving these regulations and amendments into the Illinois SIP and is
codifying this approval in the Federal regulations at 40 CFR 52.720.
Upon the effective date of this approval, PSD permits issued by IEPA
will be issued under state authority and will no longer be considered
Federal actions. However, such PSD permits will continue to be
federally enforceable as defined at 40 CFR 51.166(b)(17).
    This action also transfers to IEPA responsibility for administering
existing PSD permits that EPA previously issued to sources in Illinois
pursuant to the FIP, and for processing any PSD permit actions related
to such permits.

II. Summary of EPA Analysis

A. Procedural Requirements

    For the reasons discussed in the proposed rule, EPA finds that IEPA
has satisfied the procedural requirements for a SIP submittal as set
forth in 40 CFR 51.102, 51.103 and 40 CFR part 51, appendix V.

B. 35 Ill. Adm. Code Part 203 (Major Stationary Source Construction and
Modification)

    For the reasons discussed in the proposed rule, EPA is approving
IEPA's amendments to 35 Ill. Adm. Code Part 203. The amendments update
certain provisions in this regulation such that they refer to permits
issued under 40 CFR 52.21 or 35 Ill. Adm. Code Part 204, Illinois' new
regulation for a state PSD permitting program. Specifically, EPA is
approving amendments to 35 Ill. Adm. Code 203.207(a), (c)(2), (c)(3),
(c)(5), (c)(6), (e) and (f). Accordingly, upon the effective date of
this final action, IEPA will issue PSD permits under 35 Ill. Adm. Code
Part 204, but permits previously issued under 40 CFR 52.21 will
continue to be effective unless rescinded or otherwise rendered
invalid.

C. 35 Ill. Adm. Code Part 204

    Under 40 CFR 51.166(a)(7)(iv), each SIP shall contain the specific
provisions of 40 CFR 51.166(a)(7)(iv)(a) through (f). EPA will approve
deviations from these provisions only if the State specifically
demonstrates that the submitted provisions are more stringent than, or
at least as stringent, in all respects as the corresponding provisions
in 40 CFR 51.166(a)(7)(iv)(a) through (f). Additionally, 40 CFR
51.166(b) requires that all SIPs shall use the definitions in 40 CFR
51.166(b) for the purposes of 40 CFR 51.166 and that deviations from
the wording of those definitions will be approved only if the State
specifically demonstrates that the submitted definition is more
stringent, or at least as stringent, in all respects as the
corresponding definitions in 40 CFR 51.166(b).
    EPA finds that IEPA's PSD regulation is more stringent than, or at
least as stringent, in all respects as the corresponding provisions in
40 CFR 51.166. While IEPA has submitted provisions that differ in some
respects from the provisions in 40 CFR 51.166, as discussed in detail
in the proposed rule,\3\ we find that those differences do not render
IEPA's regulation less stringent than the corresponding Federal
language at 40 CFR 51.166.
---------------------------------------------------------------------------

    \3\ See 86 FR 22374-22380.
---------------------------------------------------------------------------

D. 35 Ill. Adm. Code Part 211 (Definitions and General Provisions)

    In the proposed rule, EPA proposed to approve amendments to 35 Ill.
Adm. Code Part 211 that updated certain provisions in this regulation
such that they refer to permits issued under 40 CPR 52.21 or 35 Ill.
Adm. Code Part 204. Specifically, EPA proposed to approve amendments to
35 Ill. Adm. Code 211.7150(b) and (d), with a state effective date of
September 4, 2020. On June 16, 2021, EPA approved into the Illinois SIP
a more recent version of this regulation, with a state effective date
of October 20, 2020. See 86 FR 31920. The October 20, 2020 version of
35 Ill. Adm. Code Part 211, as EPA approved on June 16, 2021, contains
the changes that IEPA requested in its September 22, 2020 submittal for
this action. Therefore, EPA is not acting on this portion of the
submittal in this action.

E. 35 Ill. Adm. Code Part 252 (Public Participation)

    For the reasons discussed in the proposed rule, EPA is approving
into the SIP IEPA's regulations at 35 Ill. Adm. Code Part 252, except
35 Ill. Adm. Code 252.301. EPA finds that IEPA's amendments to 35 Ill.
Adm. Code Part 252 meet the CAA requirements for public participation
for the PSD program as set forth in 40 CFR 51.161 and 51.166(q), and
are substantially identical to the public participation

requirements in 40 CFR part 124 that are pertinent to the currently-
applicable FIP incorporating 40 CFR 52.21. EPA is not including in its
final approval 35 Ill. Adm. Code 252.301 because IEPA withdrew this
provision from its submittal, and it is not a required element of a PSD
SIP.

F. Personnel, Funding, and Authority

    Section 110(a)(2)(E)(i) of the CAA requires states to have adequate
personnel, funding, and authority under state law to carry out a SIP.
EPA finds that IEPA has authority under state law to issue PSD permits.
Specifically, sections 9.l(d)(l) and (2) of the Illinois Environmental
Policy Act (Illinois Act), 415 ILCS 5/9.l(d)(l) and (2), specify that
no person shall violate any provisions of sections 111, 112, 165, or
173 of the CAA, as now or hereafter amended, or the implementing
Federal regulations; or construct, install, modify or operate any
equipment, building, facility, source or installation which is subject
to regulation under sections 111, 112, 165, or 173 of the CAA, as now
or hereafter amended, except in compliance with the requirements of
such sections and Federal regulations adopted pursuant thereto. The
Illinois Act further specifies that no such action shall be undertaken
without a permit granted by IEPA whenever a permit is required pursuant
to the Illinois Act or the implementing state regulations, or section
111, 112, 165, or 173 of the CAA or implementing Federal regulations,
or in violation of any conditions imposed by such permit. Consistent
with the Illinois Act, 35 Ill. Adm. Code 204.820 and 204.850 require
that a source may construct or operate any source or modification
subject to PSD permitting only after obtaining an approval to construct
or PSD permit. IEPA would have the ability to rescind such PSD permit
under 35 Ill. Adm. Code 204.1340.
    As discussed in the proposed rule, and in response to comments
below, EPA finds that IEPA has provided the necessary assurances that
it has adequate personnel and funding to implement PSD permitting
activities in Illinois, including an adequate number of full-time
construction permit staff and revenue stream from permit fees to
administer a PSD program in Illinois.

G. EPA Oversight Authority

    In approving state NSR rules into SIPs, EPA has a responsibility to
ensure that all states properly implement their SIP-approved
preconstruction permitting programs. Accordingly, EPA will conduct
appropriate oversight to ensure that permits issued by IEPA are
consistent with the requirements of the CAA, Federal regulations, and
the SIP.
    EPA's authority to oversee NSR permit program implementation is set
forth in sections 113 and 167 of the CAA. For example, section 167
authorizes EPA to issue administrative orders, initiate civil actions,
or take whatever other action may be necessary to prevent the
construction or modification of a major stationary source that does not
``conform to the requirements of'' the PSD program. Section 113(a)(1)
of the CAA provides for a range of enforcement remedies whenever EPA
finds that a person is in violation of an applicable implementation
plan. Likewise, section 113(a)(5) of the CAA provides for
administrative orders and civil actions whenever EPA finds that a state
``is not acting in compliance with'' any requirement or prohibition of
the CAA regarding the construction of new sources or modification of
existing sources.
    Under 40 CFR 51.166(a)(4), IEPA is obligated to review the
continued adequacy of its approved SIP ``on a periodic basis and within
60 days of such time as information becomes available that an
applicable increment is being violated.''

III. What comments did we receive on the proposed rule?

    Our proposed rule provided a 30-day public comment period. See 86
FR at 22372. During the comment period, which closed on May 28, 2021,
we received both adverse and supportive comments. We received comments
in support of our proposed rule from the Illinois Environmental
Regulatory Group. We received adverse consolidated comments from
Earthjustice, Environmental Law & Policy Center, and Sierra Club. We
respond to the adverse comments in this section.
    Comment: The commenters assert that EPA cannot approve Illinois'
PSD program into the SIP because IEPA has not provided necessary
assurances that it will have adequate personnel, funding, and authority
under State law to carry out the SIP, as required by section
110(a)(2)(E) of CAA. The commenters allege that IEPA has for many years
been understaffed and under-resourced to handle its existing volume of
regulatory obligations. Citing findings by EPA (including by the Office
of Inspector General (OIG)) and other studies, the commenters argue
that: (1) IEPA's title V program has longstanding funding and permit
processing issues, including a title V permit backlog above EPA's
recommended level as recently as 2017, suggesting the same issues will
arise with the PSD program; (2) IEPA staff has declined since 1980 (and
by nearly 50% in the Bureau of Air during the period 2003-2018); (3)
there is no general fund appropriation for IEPA; and (4) delays of
permit appeals at the Illinois Pollution Control Board (IPCB) suggest
personnel and funding issues in that body, which would delay resolution
of PSD permit appeals. The commenters allege that IEPA has not
demonstrated that the staffing and resource shortages already plaguing
it have been resolved, nor has it shown that IEPA or the IPCB have the
sufficient staff and resources necessary to equip them to implement the
PSD program. The commenters also assert that funding and staffing
shortfalls place a disproportionate burden on Environmental Justice
(EJ) communities by delaying the review and enforcement of
noncompliance with permits for sources that are disproportionately
located in EJ communities. As a result, the commenters assert that
authorizing IEPA to administer the PSD program would be inconsistent
with IEPA's and EPA's EJ obligations.
    EPA Response: EPA acknowledges that IEPA, like many other
permitting authorities, has seen staff and funding decline over the
years due to reduced legislative budget allocations, facility shutdowns
(particularly by large emitters such as coal-fired power plants), and
other factors. However, we disagree with the commenters' assertion that
IEPA has not met its burden to provide the necessary assurances that it
will have adequate personnel and funding under State law to administer
a SIP-approved PSD program in Illinois.\4\ While CAA section
110(a)(2)(E) requires each state to provide necessary assurances that
the state will have adequate personnel, funding, and authority under
state law to carry out the SIP, it does not mandate a specific
methodology for EPA to use when evaluating the adequacy of resources to
implement the SIP. See 76 FR 42549, 42554 (July 19, 2011). The scope of
this action is limited to determining whether the Illinois SIP meets
certain infrastructure requirements of CAA section 110(a)(2)(E) with
respect to funding and personnel for purposes of implementing the
approved SIP. As discussed in the proposed rule, IEPA has issued PSD
permits under the delegation agreement with EPA since 1980, and the
staff of engineers and air

quality modelers who supported IEPA in its issuance of PSD permits
under the delegation agreement will continue to support IEPA's issuance
of PSD permits under a SIP-approved PSD program. In its submittal, IEPA
stated it currently has nine full time construction permit engineers
that perform construction permit activities, and that it has an
adequate revenue stream from permit fees to support such activities.
The commenters have not provided information that would rebut these
statements from IEPA's submittal; rather, commenters provide
information that is not relevant to approval of Illinois' PSD program,
or that otherwise does not support commenters' allegations of
inadequate personnel or funding for IEPA to implement the PSD program.
---------------------------------------------------------------------------

    \4\ The commenters provided no evidence to contest EPA's finding
that IEPA has provided necessary assurances that it will have
adequate authority under State law to carry out the SIP.
---------------------------------------------------------------------------

    EPA's evaluation of Illinois' submittal with respect to funding and
personnel is based, in part, upon various sources of funding available
to the state, state statutes and rules pursuant to CAA section
110(a)(2), and IEPA's fulfillment of grant obligations. CAA section 105
grants provide monies to help support the foundation of the state's air
quality program, including air monitoring, enforcement, and SIP
development. States are required to provide matching monies to receive
their grant, and EPA evaluates the performance of the State each year.
As of fiscal year 2020, Illinois has satisfactorily completed its air
program obligations as called for under the CAA section 105 grant,
including meeting specific measures related to NSR program
implementation and maintenance of an EPA-approved statewide air quality
surveillance network required by section 110(a)(2)(B) of the CAA.
    To the extent the commenters address the adequacy of personnel or
funding for Illinois' title V program, they are addressing issues that
are subject to statutory and regulatory evaluation that are beyond the
scope of this rulemaking. CAA section 110(a)(2) falls under title I of
the CAA and governs the implementation, maintenance, and enforcement of
the NAAQS through the SIP. CAA section 110 and 40 CFR part 51 provide
mechanisms for programmatic remedies with respect to the SIP. Title I
also addresses NSR preconstruction permits for new or modified minor
and major sources. The title V program, by contrast, governs operating
permits for existing sources and is addressed by CAA sections 502
through 507. Any evaluation of the title V program and any consequent
programmatic remedies must be done pursuant to CAA section 502 and 40
CFR part 70.
    Title V programs are generally not part of the SIP, and thus are
not part of the requirements of CAA section 110(a)(2); moreover, CAA
section 502(b)(3) requires not only that title V program fees cover the
reasonable direct and indirect costs of developing and administering
the title V program, but also requires that the fees be used only to
cover those costs. See 76 FR 43906, 43910 (July 22, 2011) and 79 FR
62042, 62045 (Oct. 16, 2014). Due to the distinct and self-
administering nature of the title V program, we disagree that alleged
flaws in Illinois' title V program would prevent EPA from approving a
SIP submittal under CAA section 110(a)(2).\5\
---------------------------------------------------------------------------

    \5\ In criticizing Illinois' title V program, commenters rely in
part on EPA's Review of Illinois Environmental Protection Agency's
New Source Review and Title V Permit Programs (Sept. 2017) (the
``2017 Review''). That review noted several improvements in IEPA's
processing of PSD permits, including that it had been ``issuing all
PSD permits within 180 days of receiving a complete application,
well within the timeframe required by EPA's rules'' and had
``entered into the [RACT/BACT/LAER Clearinghouse] all BACT/LAER
determinations for issued and effective permits.'' 2017 Review at 5,
7.
---------------------------------------------------------------------------

    Commenters rely on a 2019 study of funding and staffing issues at
the IEPA, including in the Bureau of Air, to suggest that the decline
in IEPA staff since 1980 would compromise implementation of an approved
Illinois PSD program.\6\ We noted earlier in this section the specific
staff allocation that IEPA made in its submittal for implementing the
PSD program. In addition, since the 2019 study was published, staff in
IEPA's Bureau of Air has increased from 157 to an estimated 167 (with
190 targeted for FY 2021), and the enacted appropriation for the Bureau
of Air has increased from $88,964,000 in FY 2019 to $140,825,800 in FY
2020 (with $156,808,200 proposed for FY 2021).\7\

is consistent with EPA's previous finding that ``IEPA has made
improvements to its permit issuance timeliness through various
efforts, including . . . additional staffing.'' 2017 Review at 11.
---------------------------------------------------------------------------

    If, in the future, EPA determines that Illinois does not have
adequate personnel or funding to carry out its SIP, or for any other
reason fails to meet any requirement of its approved SIP, then EPA may
exercise its authority pursuant to CAA sections 110(a)(2)(E), 179, or
110(k)(5) to impose sanctions and other remedies on the State as
allowed by the CAA. The action that EPA is taking here does not limit
EPA's authority pursuant to those CAA sections. See also 77 FR 58955,
58957-8 (Sept. 25, 2012).
    With respect to the concerns regarding the IPCB, the commenters
have provided no information for EPA to conclude that personnel or
funding shortfalls have contributed to delays in IPCB permit appeal
proceedings. There are many factors that could have resulted in lengthy
permit appeal proceedings (including filing of motions for delays by
the appellant or responding party). One such factor, discussed in EPA's
2017 Review, was that the IPCB formerly would stay title V permits in
their entirety during an appeals process.\8\ In 2010, Illinois enacted
legislation allowing the IPCB to stay the effectiveness of any or all
uncontested conditions of a title V permit if the IPCB determines that
the uncontested conditions would be affected by its review of contested
conditions. See 415 ILCS 5/40.2(f). As a result of this legislation, as
well as IEPA's efforts to resolve appeals and issue affected permits,
the number of unresolved appeals has decreased significantly since
2005.

    Finally, EPA is committed to advancing EJ and incorporating equity
considerations into all aspects of our work, including ongoing
development of practices to better assess and consider impacts to
pollution-burdened communities in our analysis, permitting, and
enforcement activities. At this time EPA does not have, nor did
commenters provide, information that would suggest that approval of
Illinois' PSD program has the potential to result in disproportionately
high and adverse human health or environmental impacts on vulnerable
populations or overburdened communities; however, EPA is also not
currently in a position to make a determination to this effect. As we
work to define EJ best practices at EPA, we will continue to work with
IEPA and other stakeholders to ensure that robust analyses are
conducted to assess the full EJ implications of siting individual
facilities in communities already overburdened by pollution.
    Comment: The commenters object to IEPA removing the requirement
that limits on the potential to emit (PTE) taken to avoid major NSR
must be ``federally enforceable''; IEPA would instead require such
limits to be ``federally enforceable or legally and practicably
enforceable by a state or local air pollution control agency.'' 35

Ill. Adm. Code 204.560 (definition of ``potential to emit''). The
commenters assert that, if accepted into the SIP, this would allow IEPA
to issue minor NSR permits without public notice and an opportunity for
public comment because a source could be minor solely on the basis of
State-enforceable restrictions on PTE. Specifically, the commenters
assert that the Illinois rules governing the categories of permits
subject to public comment before issuance (35 Ill. Adm. Code 252.104
and 252.201) include sources that would be major sources except for
their federally enforceable restrictions, but do not include sources
that would be major except for state or locally enforceable
restrictions. This, the commenters allege, means that IEPA could issue
permits establishing PTE limits without public notice and an
opportunity for comment. The commenters allege that eliminating the
requirement for an opportunity for public comment on draft PTE limits
would violate EPA's minor NSR regulations at 40 CFR 51.161.
    EPA Response: We disagree with the commenters. First, as discussed
in the proposed rule, IEPA's proposed revision of the PTE definition at
35 Ill. Adm. Code 204.560 is consistent with past court decisions and
related EPA guidance that establish that the term ``potential to emit''
must encompass all legally enforceable emission limitations that
restrict a source's emissions. In Chemical Manufacturers Association v.
EPA, 70 F. 3d 637 (D.C. Cir. 1995) and National Mining Association v.
EPA, 59 F.3d 1351, 1362-63 (D.C. Cir. 1995), the term ``federally
enforceable'' was vacated in the definition of PTE (e.g., 40 CFR
51.166(b)(4)), and in subsequent memoranda, EPA stated it interpreted
the term ``federally enforceable'' to mean ``federally enforceable or
legally and practicably enforceable by a state or local air pollution
control agency'' (emphasis added).\9\ The memoranda reiterate EPA's
earlier guidance on permit conditions restricting potential to emit
that are enforceable as a practical matter. For example, practicable
enforceability for a source-specific permit means that the permit's
provisions must, at a minimum: (1) Be technically accurate and identify
which portions of the source are subject to the limitation; (2) specify
the time period for the limitation (hourly, daily, monthly, and annual
limits such as rolling annual limits); (3) be independently enforceable
and describe the method to determine compliance, including appropriate
monitoring, recordkeeping, and reporting; (4) be permanent; and (5)
include a legal obligation to comply with the limit.\10\ IEPA's PTE
definition is consistent with the relevant court decisions and EPA's
interpretation of those decisions, requiring the limits to be
``federally enforceable or legally and practicably enforceable by a
state or local air pollution control agency.'' It is therefore
appropriate for Illinois to use that phrase in place of ``federally
enforceable'' alone.
---------------------------------------------------------------------------

Enforceability of Limitations on Potential to Emit at 3-4 (Jan. 22,
1996), available at https://www.epa.gov/sites/default/files/2015-07/documents/pottoemi.pdf.
    \10\ See Memorandum entitled, ``Guidance on Limiting Potential
to Emit in New Source Permitting,'' from Terrell F. Hunt, Associate
Enforcement Counsel, Office of Enforcement and Compliance Assurance
(OECA), and John Seitz, Director, Office of Air Quality Planning and
Standards (OAQPS), to EPA Regional Offices (Jun. 13, 1989), and
Memorandum entitled, ``Options for Limiting the Potential to Emit
(PTE) of a Stationary Source Under Section 112 and Title V of the
Clean Air Act (Act),'' from John Seitz, Director, OAQPS and Robert
I. Van Heuvelen, Director, ORE to Regional Air Directors (Jan. 25,
1995).
---------------------------------------------------------------------------

    Second, although Illinois' notice and comment procedures for
synthetic minor NSR sources are beyond the scope of this action, IEPA
cannot avoid notice and comment on a synthetic minor NSR permit for a
source that has taken State-enforceable restrictions on PTE. Under CAA
section 110(a)(2)(C), State minor NSR programs approved under the SIP,
and the permits issued thereunder, are always federally enforceable.
See also 40 CFR 52.23 and CAA section 113(b)(1).\11\ Under 35 Ill. Adm.
Code 252.104 and 252.201, in addition to providing public notice for
major NSR and title V permit actions, IEPA must provide public notice
for the planned issuance of the following minor NSR permits: Permits
for the construction of a source or a modification of a source that
would constitute a new major stationary source or a major modification
of a major stationary source, if the source or modification were not
accompanied by contemporaneous emissions decreases or if federally
enforceable significant restrictions were not placed on the source or
modification by the permit; permits to operate sources that contain
federally enforceable conditions, including permits that exclude
sources from the applicability of the permitting requirements described
in 35 Ill. Adm. Code 252.104(a)(1), (a)(2) or (a)(5); and permits for
the construction of a source of public interest or emission units of
public interest at a source, the criteria for which are outlined in 35
Ill. Adm. Code 252.104(b). Thus, as relevant to synthetic minor NSR
permits, IEPA's regulations do not provide any exemption from public
notice and comment for permits for new sources or modifications that
would be major sources or major modifications but accept enforceable
restrictions on PTE such that the new source or modification becomes a
minor source. Consistent with CAA section 110(a)(2)(C), the PTE
definition in 40 CFR 51.166(b)(4) and IEPA's public participation
requirements at 35 Ill. Adm. Code 252.104(a)(3), (a)(6) and 252.201(a),
permits for such sources or modifications must be public noticed
regardless of the new level of allowable emissions (after taking into
account the federally enforceable restrictions on emissions or any
contemporaneous emissions decreases). For these reasons, IEPA cannot
avoid notice and comment on synthetic minor NSR permits for sources
accepting only State-enforceable restrictions on PTE.
---------------------------------------------------------------------------

    \11\ See also Federal Enforceability of State's Existing Minor
New Source Review (NSR) Programs (Nov. 2, 1994), available at
https://www.epa.gov/nsr/federal-enforceability-states-existing-minor-new-source-review-nsr-programs.
---------------------------------------------------------------------------

    Although not a condition of this approval, EPA expects IEPA to
implement the PTE definition in a manner that is consistent with the
courts' decisions, IEPA's PTE definition in 35 Ill. Adm. Code 204.560
and the public participation requirements in 35 Ill. Adm. Code 252.104
and 252.201, and EPA rules as discussed above. IEPA's enforcement
program must continue to provide sufficient incentive for sources to
comply with permit limits. Permit limits must be enforceable as a
practical matter (i.e., practicably enforceable), and PTE limits must
be subjected to appropriate public notice and comment consistent with
40 CFR 51.161 and IEPA's SIP-approved public participation regulations.
If, in the future, IEPA does not implement its PTE definition
consistent with its SIP-approved regulations or the CAA and its
implementing regulations (including, but not limited to, not public
noticing PTE limits or establishing limits that are not practicably
enforceable), EPA could find that IEPA has failed to adequately
administer or enforce its PSD program and may take action to notify
IEPA of such a finding as authorized by sections 110(a)(2)(E), 179, or
110(k)(5) of the CAA.
    Further, in response to a recent report by the OIG regarding EPA's
oversight of synthetic minor permits, EPA has committed to identifying
state, local, and tribal agencies whose program regulations, including
but not limited to, minor NSR and federally enforceable state operating
permit program

regulations and corresponding practices, do not meet the public
participation requirements contained in the applicable EPA regulations,
e.g., 40 CFR 51.161.\12\ For the identified agencies, EPA expects to
take appropriate corrective steps, which may include constructive,
informal, and formal engagement with those agencies.

IV. What action is EPA taking?

A. Scope of EPA Action

    EPA is approving revisions to the Illinois SIP that IEPA submitted
on September 22, 2020 and amended on November 5, 2020, and March 3,
2021. These revisions implement the PSD preconstruction permitting
regulations for certain new or modified sources in attainment and
unclassifiable areas. Currently, the PSD program in Illinois is
operated under the FIP incorporating 40 CFR 52.21. EPA is approving
IEPA's PSD regulations contained in 35 Ill. Adm. Code Parts 204 and 252
to apply statewide, except in Indian reservations.
    EPA is excluding from the scope of this final approval all Indian
reservations in the State, and any other area where EPA or an Indian
tribe has demonstrated that a tribe has jurisdiction. For the
facilities in these geographic areas, the PSD FIP incorporating 40 CFR
52.21 will continue to apply and EPA will retain responsibility for
issuing permits affecting such sources.

B. Rules Approved and Incorporated by Reference Into the SIP

    EPA approves into the Illinois SIP at 40 CFR 52.720, the following
regulations: 35 Ill. Adm. Code 203.207 ``Major Modification of a
Source'' and 35 Ill. Adm. Code Part 204 ``Prevention of Significant
Deterioration,'' effective September 4, 2020; and 35 Ill. Adm. Code
Part 252 ``Public Participation in the Air Pollution Control Program'',
except 35 Ill. Adm. Code sections 252.301 and 252.401, effective June
10, 2020.

C. Transfer of Authority for Existing EPA-Issued PSD Permits

    Since April 7, 1980, IEPA has had full delegation to implement the
PSD permitting program under the FIP. 46 FR 9580 (Jan. 29, 1981). Thus,
PSD permits issued by IEPA on or after April 7, 1980, were issued under
both state and EPA authority. Prior to delegation of the PSD permitting
program to IEPA on April 7, 1980, EPA issued several PSD permits for
sources in Illinois.\13\ In an April 14, 1982 amendment to the terms of
the 1980 delegation agreement, EPA delegated to IEPA the authority to
amend or to revise any permits that had been previously issued by EPA.
---------------------------------------------------------------------------

    \13\ EPA issued at least 18 such permits; however, some of the
affected facilities may no longer exist. The full listing of these
facilities is available in the docket for this action.
---------------------------------------------------------------------------

    In this action, EPA is granting IEPA authority to fully administer
the PSD program with respect to those sources under IEPA's permitting
jurisdiction that have existing PSD permits issued solely by EPA on or
before April 7, 1980. This includes authority to conduct general
administration of these existing permits, authority to process and
issue any subsequent PSD permit actions relating to such permits (e.g.,
modifications, amendments, or revisions of any nature), and authority
to enforce such permits. IEPA has demonstrated adequate authority to
enforce and modify these permits.

V. Incorporation by Reference

    In this rule, EPA is finalizing regulatory text that includes
incorporation by reference. In accordance with requirements of 1 CFR
51.5, EPA is finalizing the incorporation by reference of the Illinois
Regulations described in the amendments to 40 CFR part 52 set forth
below. EPA has made, and will continue to make, these documents
generally available through www.regulations.gov, and at the EPA Region
5 Office (please contact the person identified in the FOR FURTHER
INFORMATION CONTACT section of this preamble for more information).
Therefore, these materials have been approved by EPA for inclusion in
the SIP, have been incorporated by reference by EPA into that plan, are
fully federally enforceable under sections 110 and 113 of the CAA as of
the effective date of the final rulemaking of EPA's approval, and will
be incorporated by reference in the next update to the SIP compilation.

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 (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).
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this action and
other required information to the U.S. Senate,

the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of the rule in the Federal Register.
A major rule cannot take effect until 60 days after it is published in
the Federal Register. This action is not a ``major rule'' as defined by
5 U.S.C. 804(2).
    Under section 307(b)(1) of the CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by November 8, 2021. Filing a petition for
reconsideration by the Administrator of this final rule does not affect
the finality of this action for the purposes of judicial review nor
does it extend the time within which a petition for judicial review may
be filed, and shall not postpone the effectiveness of such rule or
action. This action may not be challenged later in proceedings to
enforce its requirements (see CAA section 307(b)(2)).
