Air Plan Approval; Illinois; Base Year Emissions Inventory for 
the 2015 Ozone Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve, under the Clean Air Act (CAA), revisions to the State 
Implementation Plan (SIP) submitted by the Illinois Environmental 
Protection Agency on October 22, 2020, and February 14, 2023. The 
revisions address the emissions inventory requirements for the Chicago 
and Metro-East nonattainment areas under the 2015 ozone National 
Ambient Air Quality Standard. The Chicago nonattainment area includes 
Cook, DuPage, Grundy (Aux Sable and Goose Lake Townships), Kane, 
Kendall (Oswego Township), Lake, McHenry, and Will counties. The Metro-
East nonattainment area includes Madison, Monroe, and St. Clair 
counties. The CAA requires emissions inventories for all ozone 
nonattainment areas.

DATES: Comments must be received on or before September 14, 2023.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R05-
OAR-2020-0555 at https://www.regulations.gov or via email to 
[email protected]. For comments submitted at Regulations.gov, 
follow the online instructions for submitting comments. Once submitted, 
comments cannot be edited or removed from Regulations.gov. For either 
manner of submission, EPA may publish any comment received to its 
public docket. Do not submit electronically any information you 
consider to be Confidential Business Information (CBI) 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 or multimedia

FOR FURTHER INFORMATION CONTACT: Emily Crispell, Environmental 
Scientist, Control Strategies Section, Air Programs Branch (AR18J), 
Environmental Protection Agency, Region 5, 77 West Jackson Boulevard, 
Chicago, Illinois 60604, (312) 353-8512, [email protected]. The 
EPA Region 5 office is open from 8:30 a.m. to 4:30 p.m., Monday through 
Friday, excluding Federal holidays and facility closures due to COVID-
19.

SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal 
Register, EPA is approving the state's SIP submittal as a direct final 
rule without prior proposal because the Agency views this as a 
noncontroversial submittal 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.
