Federal Register / Vol. 86, No. 186 / Wednesday, September 29, 2021 / Rules and Regulations stakeholders such as Partners for Clean Air in Chicago, the Clean Air Partnership in St. Louis, and the Cook County Department of Environmental Control. The State maintains portions of its website specifically for air quality alerts,11 and prepares annual data reports from its complete monitoring network and provides a daily air quality index to the public and media.
Therefore, EPA finds that Illinois has met the infrastructure SIP requirements of this portion of section 110a2J
with respect to the 2012 PM2.5 and 2015
ozone NAAQS.
3. PSD
States must meet applicable requirements of section 110a2C
related to PSD. Illinois PSD program in the context of infrastructure SIPs has already been discussed above in the paragraphs addressing section 110a2C and section 110a2DiII, and EPA notes that the findings for those sections are consistent with the findings for this portion of section 110a2J.
Therefore, EPA finds that Illinois has met all the infrastructure SIP
requirements for PSD associated with section 110a2J for the 2012 PM2.5
and 2015 ozone NAAQS.

4. Visibility Protection States are subject to visibility and regional haze program requirements under part C of the CAA which includes sections 169A and 169B. In the event of the establishment of a new NAAQS, however, the visibility and regional haze program requirements under part C do not change. Thus, we find that there is no new visibility obligation triggered under section 110a2J when a new NAAQS
becomes effective. In other words, the visibility protection requirements of section 110a2J are not germane to infrastructure SIPs for the 2012 PM2.5
and 2015 ozone NAAQS.
K. Section 110a2KAir Quality Modeling/Data SIPs must provide for performance of air quality modeling to predict the effects on air quality from emissions of any NAAQS pollutant and the submission of such data to EPA upon request.
IEPA maintains the capability and authority to perform modeling of the air quality impacts of emissions of all criteria pollutants, including the capability to use complex photochemical grid models per 415

ILCS 54. This modeling is used in support of the SIP for all nonattainment areas in the state. IEPA also requires air quality modeling in support of permitting the construction of major and some minor new sources under the PSD
program. These modeling data are available to EPA as well as the public upon request. Lastly, IEPA participates in LADCO, which conducts regional modeling that is used for statewide planning purposes. EPA finds that Illinois has met the infrastructure SIP
requirements of section 110a2K
with respect to the 2012 PM2.5 and 2015
ozone NAAQS.
L. Section 110a2LPermitting Fees This section requires SIPs to mandate each major stationary source to pay permitting fees to cover the cost of reviewing, approving, implementing, and enforcing a permit.
IEPA implements and operates the title V permit program, which EPA
approved on December 4, 2001 66 FR
62946, and the provisions, requirements, and structures associated with the costs for reviewing, approving, implementing, and enforcing various types of permits are contained in 415
ILCS 5/39.5. As previously mentioned, IEPA states that 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. Further, IEPA
has increased BOA staffing and appropriation from 2019 to 2020, with projected increases continuing through 2021. EPA finds that Illinois has met the infrastructure SIP requirements of section 110a2L with respect to the 2012 PM2.5 and 2015 ozone NAAQS.
M. Section 110a2MConsultation/
Participation by Affected Local Entities States must consult with and allow participation from local political subdivisions affected by the SIP.
All public participation procedures pertaining to IEPA are consistent with 35 IAC Part 164 Procedures for Informational and Quasi-Legislative Public Hearings and 35 IAC Part 252
Public Participation in the Air Pollution Control Permit Program; the latter is an approved portion of Illinois SIP. See 50 FR 38803 June 1, 1984 and 86 FR 21207 April 22, 2021. EPA finds that Illinois has met the infrastructure SIP requirements of section 110a2M
with respect to the 2012 PM2.5 and 2015
ozone NAAQS.
III. Applicability of PSD Requirements As previously mentioned, IEPA
submitted to EPA a request on

September 22, 2020, to revise the Illinois SIP to establish a SIP-approved PSD program in Illinois, replacing the previous FIP. IEPA requested that EPA
incorporate into the SIP Title 35 IAC
Part 204 containing the new PSD
program, and revisions to 35 IAC Parts 252 and 203. The request was approved on September 9, 2021 86 FR 50459, and addressed comments received during EPAs public comment period.
While this action primarily addresses the 2012 PM2.5 and 2015 ozone NAAQS, EPA is approving several elements for the 1997 ozone, 1997 PM2.5, 2006 PM2.5, 2008 ozone, 2008 lead, 2010 NO2, and 2010 SO2 NAAQS. Specifically, EPA is approving elements 110a2C, D and J pertaining to PSD requirements. For 110a2C, IEPAs new PSD program addresses: i PSD provisions that explicitly identify NOX as a precursor to ozone in the PSD program; ii identification of precursors to PM2.5 and the identification of PM2.5 and PM10
condensables in the PSD program; iii PM2.5 increments in the PSD program;
and iv GHG permitting and the Tailoring Rule in the PSD program.
IEPAs new PSD program also addresses the requirements under 110a2D to ensure that sources located in nonattainment areas do not interfere with a neighboring states PSD program as well as meeting requirements relating to interstate and international pollution abatement. EPA notes that the findings for sections C and D are consistent with the findings for this portion of section 110a2J. IEPAs satisfaction of these elements is discussed in the appropriate sections above. Because EPA is acting on the Illinois submittal for a minimal quantity of the 110a2
infrastructure elements for the referenced NAAQS, these elements are not included in the table in the following section, but are contained in the codification of this action. EPA finds that Illinois has met the infrastructure SIP requirements of sections 110a2C, DiII, Dii, and J
pertaining to PSD requirements with respect to the 1997 ozone, 1997 PM2.5, 2006 PM2.5, 2008 ozone, 2008 lead, 2010
NO2, and 2010 SO2 NAAQS.
IV. What action is EPA taking?
EPA is approving most elements of a submission from IEPA certifying that its current SIP is sufficient to meet the required infrastructure elements under sections 110a1 and 2 for the 2012
PM2.5 and 2015 ozone NAAQS.12 The 12 EPA emphasizes that the recently approved PSD provisions discussed in 110a2C, D and J
are not limited to ozone and PM2.5. See
