AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve State Implementation Plan (SIP) revisions submitted by the 
Illinois Environmental Protection Agency (IEPA or Illinois). The 
revisions, submitted on February 26, 2024, and July 8, 2024, update the 
Illinois air pollution control rules entitled ``Part 243--Ambient Air 
Quality Standards'' in response to EPA rulemakings and changes to the 
National Ambient Air Quality Standards (NAAQS) that EPA adopted in 2022 
and 2023.

DATES: Comments must be received on or before November 4, 2024.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R05-
OAR-2024-0105 or EPA-R05-OAR-2024-0320 at https://www.regulations.gov, 
or via email to <a href="/cdn-cgi/l/email-protection#670615150649140615060f2702170649000811"><span class="__cf_email__" data-cfemail="f091828291de8391829198b0958091de979f86">[email protected]</span></a>. For comments submitted at 
Regulations.gov, follow the online instructions for submitting 
comments. Once submitted, comments cannot be edited or removed from the 
docket. EPA may publish any comment received to its public docket. Do 
not submit electronically any information you consider to be 
Confidential Business Information (CBI), Proprietary Business 
Information (PBI), or other information whose disclosure is restricted 
by statute. Multimedia submissions (audio, video, etc.) must be 
accompanied by a written comment. The written comment is considered the 
official comment and should include discussion of all points you wish 
to make. EPA will generally not consider comments or comment contents 
located outside of the primary submission (i.e., on the web, cloud, or 
other file sharing system). For additional submission methods, please 
contact the person identified in the FOR FURTHER INFORMATION CONTACT 
section. For the full EPA public comment policy, information about CBI, 
PBI, or multimedia submissions, and general guidance on making 
effective comments, please visit https://www.epa.gov/dockets/commenting-epa-dockets.

SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal 
Register, EPA is approving the state's SIP submittals as a direct final 
rule

[[Page 80446]]

without prior proposal because the Agency views these as 
noncontroversial submittals and anticipates no adverse comments. A 
detailed rationale for the approval is set forth in the direct final 
rule. If no relevant adverse comments are received in response to this 
rule, no further activity is contemplated. If EPA receives such 
comments, the direct final rule will be withdrawn and all public 
comments received will be addressed in a subsequent final rule based on 
this proposed rule. EPA will not institute a second comment period. Any 
parties interested in commenting on this action should do so at this 
time. Please note that if EPA receives adverse comment on an amendment, 
paragraph, or section of this rule and if that provision may be severed 
from the remainder of the rule, EPA may adopt as final those provisions 
of the rule that are not the subject of an adverse comment. For 
additional information, see the direct final rule which is located in 
the Rules section of this Federal Register.

    Dated: September 27, 2024.

Regional Administrator, Region 5.
