Air Plan Approval; Illinois; NAAQS and VOC Updates

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve revised rules submitted by the State of Illinois as State 
Implementation Plan (SIP) revisions. The submitted rules update 
Illinois ambient air quality rules to update definitions and 
requirements for handling monitoring data influenced by exceptional 
events, implementation rules for the 2012 primary annual National 
Ambient Air Quality Standard (NAAQS) for fine particulate matter 
(PM2.5), and designated reference and equivalent methods for 
multiple NAAQS. In addition, the submitted rules amend the Illinois 
Administrative Code (IAC) by updating the definition of volatile 
organic compounds (VOC).

DATES: Comments must be received on or before January 22, 2019.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA R05 
OAR 2018-0302, EPA-RO5-OAR-2018-0303, or EPA-RO5-OAR-2018-0589 at 
http://www.regulations.gov, or via email to aburano.douglas@epa.gov. 
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 http://www2.epa.gov/dockets/commenting-epa-dockets.

FOR FURTHER INFORMATION CONTACT: Samantha Panock, Physical Scientist, 
Attainment Planning and Maintenance Section, Air Programs Branch (AR-
18J), Environmental Protection Agency, Region 5, 77 West Jackson 
Boulevard, Chicago, Illinois 60604, (312) 353-8973, 
panock.samantha@epa.gov.

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.

    Dated: December 3, 2018.

Regional Administrator, Region 5.
