ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R05-OAR-2023-0482; FRL-11618-01-R5]


Air Plan Approval; Indiana; Lake and Porter 2008 Ozone NAAQS 
Maintenance Plan Revision

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve Indiana's September 21, 2023, state implementation plan (SIP) 
submission which revises the 2008 ozone maintenance plan for the 
Indiana Portion (Lake and Porter Counties) of the Chicago Naperville, 
IL-IN-WI area. This SIP submission updates onroad vehicle emissions 
inventories for oxides of nitrogen (NOX) and volatile 
organic compounds (VOC) for the years 2019, 2030 and 2035. In addition 
to updated emissions inventories, this SIP revision updates the Motor 
Vehicle Emissions Budgets (budgets) for NOX and VOC for the 
years 2030 and 2035. EPA is proposing to approve the allocation of a 
portion of the safety margins for NOX and VOC in the ozone 
maintenance plan to the 2030 and 2035 budgets. Total year 2030 and 2035 
emissions of NOX and VOC for the area will remain below the 
attainment level required by the transportation conformity regulations.

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

other file sharing system). For additional submission methods, please

SUPPLEMENTARY INFORMATION: In the Rules and Regulations section of this 
issue of the 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receives such comments, the direct final rule will be withdrawn and all 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 issue of the Federal Register.
