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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve 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 (PM2.5) and 2015 ozone 
National Ambient Air Quality Standards (NAAQS). Additionally, EPA is 
proposing to approve 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.

DATES: Comments must be received on or before October 29, 2021.

SUPPLEMENTARY INFORMATION: In the Rules and Regulations 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comments, the direct final rule will be withdrawn and all public 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.

    Dated: September 22, 2021.

Acting Regional Administrator, Region 5.
