Air Plan Approval; Illinois; Infrastructure SIP Requirements for 
the 2012 PM2.5 and 2015 Ozone NAAQS

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving 
elements of a State Implementation Plan (SIP) revision submitted by the 
State of Illinois regarding the infrastructure requirements of section 
110 of the Clean Air Act (CAA) for the 2012 annual fine particulate 
matter (PM<INF>2.5</INF>) and 2015 ozone National Ambient Air Quality 
Standards (NAAQS). Further, EPA is approving the infrastructure 
requirements related to Prevention of Significant Deterioration (PSD) 
for previous 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. EPA received comments on its September 29, 2021, 
proposed rule and withdrew the accompanying Direct Final Rule (DFR). 
After considering the comments, EPA is approving the revisions to the 
Illinois SIP as requested by the State on September 29, 2017, May 16, 
2019, and September 22, 2020.

DATES:  This final rule is effective on May 9, 2022.

I. Background

    On September 29, 2021 (86 FR 53872), EPA published a DFR approving 
elements of infrastructure SIP revisions submitted by the Illinois 
Environmental Protection Agency (IEPA) on September 29, 2017, May 16, 
2019, and September 22, 2020, to address the infrastructure 
requirements of CAA sections 110(a)(1) and (2) for the 2012 
PM<INF>2.5</INF> and 2015 ozone NAAQS, respectively. In the DFR, EPA 
also approved the infrastructure requirements related to Prevention of 
Significant Deterioration (PSD) \1\ for 1997 ozone, 1997 
PM<INF>2.5</INF>, 2006 PM<INF>2.5</INF>, 2008 ozone, 2008 lead, 2010 
Nitrogen Dioxide (NO<INF>2</INF>), and 2010 Sulfur Dioxide 
(SO<INF>2</INF>) NAAQS. An explanation of the CAA requirements, a 
detailed analysis of the SIP submission, and EPA's reasons for 
proposing approval were provided in the DFR and will not be restated 
here.
---------------------------------------------------------------------------

    \1\ Previously, PSD permits in Illinois have been issued under a 
Federal Implementation Plan (FIP). Since April 7, 1980, IEPA has 
issued PSD permits under a delegation agreement with EPA that 
authorizes IEPA to implement the FIP (January 29, 1981, 46 FR 9580). 
Under a November 16, 1981 amendment to the 1980 Delegation 
Agreement, IEPA also had the authority to amend or revise any PSD 
permit issued by EPA under the FIP. See 86 FR 22372, 22373 (April 
28, 2021). On September 22, 2020, IEPA submitted to EPA a request to 
revise the Illinois SIP to establish a SIP-approved PSD program in 
Illinois, which was approved on September 9, 2021 (86 FR 50459), and 
addressed comments received during EPA's public comment period.
---------------------------------------------------------------------------

    In the DFR, EPA stated that if adverse comments were received by 
October 29, 2021, the rule would be withdrawn and not take effect. On 
October 27, 2021, EPA received one set of adverse comments and, as a 
result, revised its regulations on January 18, 2022 (87 FR 2554), 
because EPA was unable to withdraw the DFR before it took effect. EPA 
is addressing the comments in this final action based upon the notice 
of proposed rulemaking (NPRM) also published on September 29, 2021. See 
86 FR 53915.

II. EPA's Response to Comments

    A summary of the comments, and EPA's response, is provided below.
    Comment: The commenters state that EPA should not have used a DFR 
for this action because EPA did not have good cause under 5 U.S.C. to 
forgo normal notice-and-comment procedures (i.e., publishing an NPRM 
and accepting comments 30 days before the rule's effective date), 
because EPA allegedly did not find that compliance with the 30-day 
requirement was either ``impracticable, unnecessary, or contrary to the 
public interest,'' nor did EPA incorporate such a finding ``and a brief 
statement of the reasons therefor'' in the DFR. 5 U.S.C. 553(b)(B). In 
the DFR, EPA stated that this action was a ``noncontroversial 
amendment'' to the existing Illinois SIP and that it anticipated no 
adverse comments. The commenters argue that these statements fail to 
satisfy the good cause exemption under 5 U.S.C. 553. The commenters 
assert that infrastructure SIP actions, even when the public fails to 
comment, are not necessarily ``noncontroversial,'' because such actions 
involve detailed reviews and have been subject to litigation. For this 
reason, the commenters argue EPA should never use DFRs to approve an 
infrastructure SIP submission. The commenters encourage EPA to commence 
a separate rulemaking to govern its use of DFRs.
    Response: EPA disagrees that it was inappropriate to use a DFR for 
this infrastructure SIP action. Since September 1981, EPA has used DFRs 
for SIP actions that are noncontroversial and where it reasonably 
expects no adverse public comments.\2\ These

[[Page 20716]]

actions have included approvals of infrastructure SIP submittals.\3\ 
EPA's current procedure for these types of actions, as described in the 
DFR,\4\ has been to publish a DFR for the SIP action and at the same 
time commence a conventional rulemaking proceeding for the same rule by 
publishing a NPRM.\5\ If EPA receives adverse comments within 30 days 
after publishing the DFR, it withdraws the DFR by publishing a 
withdrawal action in the Federal Register; the substance of the DFR 
then serves as the detailed basis for the NPRM, and EPA addresses the 
adverse comments in the final rule. EPA believes this approach ``can 
save time and resources while maintaining the public's right to 
comment.'' \6\
---------------------------------------------------------------------------

    \2\ See 46 FR 44476, 44477 (Sept. 4, 1981) (``Because of the 
straightforward nature of some actions or the narrowness of their 
scope, many SIP revisions get few, if any, comments from the public 
during the comment period.''); 47 FR 27073, 27074 (June 23, 1982) 
(``as part of EPA's new SIP processing program, a SIP revision that 
is judged by EPA to be noncontroversial and where no adverse public 
comments are anticipated, will be published as a final rulemaking 
without first going through a proposed rulemaking phase''); 59 FR 
24054, 24054 (May 10, 1994) (actions that are noncontroversial, and 
where no adverse public comment is anticipated, ``do not have to be 
limited to trivial administrative changes''). See also Ronald M. 
Levin, Direct Final Rulemaking, 64 Geo. Wash. L. Rev. 1, 4-6 (1995); 
Memorandum from Leslye Fraser, Asst. Gen. Counsel, U.S. EPA, 
Guidance on Direct Final Rulemaking (Oct. 29, 1998), available at 
https://cfpub.epa.gov/oarwebadmin/sipman/sipman/mAppContent.cfm?chap=99&OtherFile=appendix/dfrguide&RequestTimeOut=500 (actions that are noncontroversial and 
for which EPA expects no adverse comment ``generally include non-
controversial amendments, non-controversial rulemakings, and routine 
or minor actions'').
    \3\ For recent examples, see 85 FR 14578 (March 13, 2020) and 82 
FR 43848 (September 20, 2017).
    \4\ 86 FR 53880 (September 29, 2021).
    \5\ For EPA's description of this procedure, see 59 FR at 24054 
(May 10, 1994) and Fraser, supra note 2. See also 47 FR 27074 (June 
23, 1982) (requiring EPA to state in DFRs for SIP revisions that 
``no comments are anticipated and that, unless notice is received 
within 30 days that someone wishes to submit adverse or critical 
comments, the rulemaking will be effective 60 days from the date the 
notice is published'').
    \6\ 46 FR 44777 (September 8, 1981).
---------------------------------------------------------------------------

    EPA viewed Illinois' infrastructure SIP submissions for these 
specific NAAQS as noncontroversial and anticipated no adverse comment 
for two reasons. First, EPA believed that Illinois' SIP submissions for 
these NAAQS straightforwardly met the relevant CAA infrastructure SIP 
requirements. Second, IEPA in its own state level rulemaking process to 
develop the infrastructure SIP submissions held 30-day periods for the 
public to comment on or to submit public hearing requests for the 2012 
PM<INF>2.5</INF> and 2015 ozone NAAQS (on June 23, 2017 and November 
16, 2018, respectively), but IEPA received no requests for a public 
hearing during the comment periods and no comments on the portions of 
the Illinois submission addressed in the DFR.\7\ The DFR included these 
details on the state level actions.\8\ Because IEPA received no 
comments on the portions of Illinois' submissions on which EPA is 
acting during its own public comment periods, EPA did not believe the 
proposed SIP revision was controversial and expected no public comments 
for this action.
---------------------------------------------------------------------------

    \7\ Illinois' September 22, 2020, submittal also requested a SIP 
revision to establish a SIP-approved PSD program in Illinois. EPA 
approved the PSD permitting program on September 9, 2021 (86 FR 
50459). In the final rule, EPA responded to adverse comments 
received during the public comment period for its proposed approval 
of Illinois' PSD program. Further, IEPA received comments on section 
110(a)(2)(D)(i)(I) Prongs 1 and 2 pertaining to interstate transport 
requirements, of which EPA disapproved on February 22, 2022 (87 FR 
9838).
    \8\ 86 FR at 53873.
---------------------------------------------------------------------------

    As the commenters point out, and consistent with Agency policy, EPA 
made a brief statement in the DFR that it viewed the action as a 
noncontroversial SIP amendment and anticipated no adverse comments.\9\ 
In response to the adverse comments, EPA removed the DFR and is 
addressing the comments in this rule. As the NPRM and the DFR appeared 
on the same day in the Federal Register (September 29, 2021), EPA's 
procedure preserved the public's opportunity to comment on this action.
---------------------------------------------------------------------------

    \9\ Id. at 53880. Nearly identical statements appear in recent 
DFRs, supra n.3. See 85 FR at 14584 (March 13, 2020); 82 FR at 43849 
(September 20, 2017). They are all consistent with the guidance in 
the Fraser Memorandum, supra n.2.
---------------------------------------------------------------------------

    Comment: The commenters argue that the EPA's proposed approval of 
Illinois' submittal, which considered the 2021 Annual Air Monitoring 
Network Plan (the ``plan'') for satisfaction of CAA section 
110(a)(2)(B), should have considered the 2022 plan.
    Response: EPA disagrees that approval of the monitoring plan 
requirements of CAA section 110(a)(2)(B) cannot be finalized without 
approval of the 2022 plan. At the time of the proposal, EPA was still 
in the process of reviewing the 2022 plan. The 2021 plan was the most 
recently approved plan, and hence was the correct plan to reference for 
satisfaction of CAA section 110(a)(2)(B). As the commenters suggest, 
EPA was working with IEPA to establish a lead monitor location for 
approval as part of the 2022 plan, but this change would not affect the 
ability of the State to monitor PM<INF>2.5</INF> and ozone; in fact, 
the number of ozone and PM<INF>2.5</INF> monitors will not change under 
the 2022 plan.\10\ Further, IEPA's submittal satisfies other 
requirements of CAA section 110(a)(2)(B) as discussed in the proposal. 
To fulfill monitoring network obligations, the submission must 
demonstrate that the state: (i) Monitors air quality at appropriate 
locations throughout the state using EPA-approved Federal Reference 
Method or Federal Equivalent Method monitors; (ii) submits data to 
EPA's Air Quality System in a timely manner; and (iii) provides EPA 
Regional Offices with prior notification of any planned changes to 
monitoring sites or the network plan.\11\ All of the above elements are 
met by IEPA's submittal. Therefore, EPA continues to find that Illinois 
has met the infrastructure SIP requirements of CAA section 110(a)(2)(B) 
with respect to the 2012 PM<INF>2.5</INF> and 2015 ozone NAAQS.
---------------------------------------------------------------------------

    \10\ The 2022 plan is available on IEPA's website and was 
available for public comment in July 2021. The 2022 plan has since 
been approved by EPA as of December 21, 2021.
    \11\ See generally, 40 CFR part 58.
---------------------------------------------------------------------------

    Comment: Lastly, the commenters claim that Illinois failed to 
provide necessary assurances under CAA section 110(a)(2)(E) that the 
state will have adequate funding and personnel to carry out its 
approved SIP. In particular, the commenters claim that the assurances 
IEPA did provide are vague and limited to permitting activities. The 
commenters also allege that IEPA has for many years been understaffed 
and under-resourced to handle its existing volume of regulatory 
obligations.
    Response: EPA disagrees that IEPA has not provided sufficient 
information about its funding and personnel to provide necessary 
assurances as required by section 110(a)(2)(E). EPA acknowledges that 
IEPA has had staff and funding declines over the years due to reduced 
legislative budget allocations, facility shutdowns that result in 
reduced permitting fees (particularly by large emitters such as coal-
fired power plants), and other factors. However, EPA disagrees that 
IEPA's assurances to meet CAA section 110(a)(2)(E) are too vague and 
limited to permitting. In response to the commenter's concern, EPA has 
again evaluated the information provided concerning its funding and 
personnel for implementation of its SIP and has concluded that IEPA has 
provided necessary assurances sufficient to meet the requirements of 
section 110(a)(2)(E) with respect to the 2012 PM<INF>2.5</INF> and 2015 
ozone NAAQS.
    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). Even so, the commenters only highlight budget cuts at 
IEPA leading up to 2018, but do not

[[Page 20717]]

consider increases in IEPA's revenue and budget. For instance, as 
discussed in IEPA's referenced submissions, Public Act 097-0095/House 
Bill 1297 \12\ was signed into effect in 2011 by the Illinois Governor 
to increase operating permit fees. More recently, EPA notes the 
increase in enacted funding for IEPA to $380 million in 2019, $450 
million in 2020, and $514 million in 2021.\13\ Further, staff in IEPA's 
Bureau of Air has increased from 164 to an estimated 185 (with 194 
targeted for FY 2022), and the enacted appropriation for the Bureau of 
Air has increased from $147,825,800 in FY 2020 to $156,808,200 in FY 
2021 (with $158,536,300 proposed for FY 2022).\14\
---------------------------------------------------------------------------

    \12\ See Chapter 415, section 5 of the Illinois Compiled 
Statutes (415 ILCS 5/9.6).
    \13\ See https://www2.illinois.gov/sites/budget/Pages/InteractiveBudget.aspx (last visited Feb. 1, 2022). The enacted 
total IEPA budget for 2021 appears to be the same figure as proposed 
by the Illinois Governor. See https://www2.illinois.gov/sites/budget/Documents/Budget%20Book/FY2021-Budget-Book/Fiscal-Year-2021-Operating-Budget-Book.pdf at 79.
    \14\ See Ill. Office of Mgmt. & Budget, Exec. Office of the 
Governor, Ill. State Operating Budget, Fiscal Year 2022, available 
at https://www2.illinois.gov/sites/budget/Documents/Budget%20Book/FY2022-Budget-Book/Fiscal-Year-2022-Operating-Budget.pdf.
---------------------------------------------------------------------------

    While the commenters expressed concern that that IEPA's statement 
about its current number of full-time permit engineers and the revenue 
stream from permit fees is unreasonably vague and can't be relied upon 
for SIP approval, EPA did not rely solely on this statement in 
evaluating Illinois' submittal with respect to funding and personnel. 
In addition to the budget figures cited above and other sources of 
funding available to the State under State statutes and rules pursuant 
to CAA section 110(a)(2), EPA considered IEPA's fulfillment of its 
obligations under the Performance Partnership Agreement with EPA.\15\ 
EPA also considered IEPA's fulfillment of its grant obligations under 
CAA section 105, which provides 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. EPA determined in July 2021 that, 
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 maintenance of an EPA-
approved statewide air quality surveillance network required by section 
110(a)(2)(B) of the CAA.
---------------------------------------------------------------------------

    \15\ See https://www2.illinois.gov/epa/about-us/Pages/performance-partnership-agreement.aspx.
---------------------------------------------------------------------------

    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.\16\
---------------------------------------------------------------------------

    \16\ See also, 86 FR 50459, 50462.
---------------------------------------------------------------------------

III. What action is EPA taking?

    EPA is approving the majority of two infrastructure SIP submissions 
from IEPA to address the required infrastructure elements under 
sections 110(a)(1) and (2) for the 2012 PM<INF>2.5</INF> and 2015 ozone 
NAAQS.\17\ The table below summarizes EPA's actions on Illinois' 
submittal in satisfaction of the infrastructure SIP requirements 
pursuant to section 110(a)(2).\18\ Additionally, EPA is approving 
Illinois' submission as meeting the infrastructure SIP requirements of 
sections 110(a)(2)(C), (D)(i)(II), (D)(ii), and (J) pertaining to PSD 
requirements with respect to the 1997 ozone, 1997 PM<INF>2.5</INF>, 
2006 PM<INF>2.5</INF>, 2008 ozone, 2008 lead, 2010 NO<INF>2</INF>, and 
2010 SO<INF>2</INF> NAAQS.
---------------------------------------------------------------------------

    \17\ EPA emphasizes that the recently approved PSD provisions 
discussed in 110(a)(2)(C), (D) and (J) are not limited to ozone and 
PM<INF>2.5</INF>. See Applicability of PSD requirements section in 
the DFR for more information on elements approved for the 1997 
ozone, 2008 ozone, 2008 lead, 2010 NO<INF>2,</INF> 1997 
PM<INF>2.5</INF>, 2006 PM<INF>2.5</INF>, and 2010 SO<INF>2</INF> 
NAAQS. 86 FR at 53879.
    \18\ In the time since proposed approval of this action, the 
portion of IEPA's submission addressing 2015 ozone transport, 
section 110(a)(2)(D)(i)(I) prongs 1 and 2 has been proposed for 
disapproval (February 22, 2022, 87 FR 9838).

IV. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the CAA and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves state law as meeting Federal requirements and 
does not impose additional requirements beyond those imposed by state 
law. For that reason, this action:
    <bullet> 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);
    <bullet> Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
    <bullet> 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.);
    <bullet> 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);
    <bullet> Does not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
    <bullet> Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
    <bullet> Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
    <bullet> 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
    <bullet> 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).
    This action is subject to the Congressional Review Act, and EPA 
will submit a rule report to each House of the Congress and to the 
Comptroller General of the United States. 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 June 7, 2022. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this action for the purposes of judicial review nor 
does it extend the time within which a petition for judicial review may 
be filed, and shall not postpone the effectiveness of such rule or 
action. This action may not be challenged later in proceedings to 
enforce its requirements. (See section 307(b)(2).)
