40 CFR Part 52

Air Plan Approval; Illinois; NAAQS Updates

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving revised 
rules submitted by the State of Illinois as State Implementation Plan 
(SIP) revisions. The submitted rules update Illinois' ambient air 
quality standards to include the 2015 primary National Ambient Air 
Quality Standard (NAAQS) for ozone (O3), add EPA-promulgated 
monitoring methods for multiple NAAQS, and address EPA's revocation of 
the 1997 O3 NAAQS. In addition, the revised rules contain 
the timing requirements for the ``flagging of exceptional events'' and 
the submission of documentation supporting exceptional events for the 
initial area designations for the 2015 primary annual O3 
standard. These SIP revisions update Illinois air pollution control 
regulations to be ``identical-in-substance'' to EPA rulemakings related 
to the NAAQS that occurred between January 1, 2014 and July 13, 2016.

DATES: Comments must be received on or before August 17, 2017.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R05-
OAR-2016-0512, EPA-R05-OAR-2016-0522, or EPA-R05-2017-0322 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 submissions, and general guidance on making effective 
comments, please visit https://www2.epa.gov/dockets/commenting-epa-dockets.

FOR FURTHER INFORMATION CONTACT: Michelle Becker, Life Scientist, 
Attainment Planning and Maintenance Section, Air Programs Branch (AR-
18J), Environmental Protection Agency, Region 5, 77 West Jackson 
Boulevard, Chicago, Illinois 60604, (312) 886-3901, 
[email protected].

SUPPLEMENTARY INFORMATION: In the Final Rules 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 adverse comments are received in response to this rule, no 
further activity is contemplated. If EPA receives adverse 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.
