ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R07-OAR-2017-0515; FRL-9968-79-Region 7]


Approval of Missouri Air Quality Implementation Plans; 
Infrastructure SIP Requirements for the 2010 Sulfur Dioxide National 
Ambient Air Quality Standard

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 from the 
State of Missouri for the 2010 Sulfur Dioxide (SO<INF>2</INF>) National 
Ambient Air Quality Standard (NAAQS). Section 110 of the CAA requires 
that each state adopt and submit a SIP for the implementation, 
maintenance, and enforcement of each new or revised NAAQS promulgated 
by EPA. These SIPs are commonly referred to as ``infrastructure'' SIPs. 
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. In the 
``Rules and Regulations'' section of this Federal Register, we are 
approving the state's SIP revisions as a direct final rule without a 
prior proposed rule. If we receive no adverse comment, we will not take 
further action on this proposed rule.

DATES: Comments must be received by November 6, 2017.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R07-
OAR-2017-0515, to https://www.regulations.gov. Follow the online 
instructions for submitting comments. Once submitted, comments cannot 
be edited or removed from Regulations.gov. The 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. The 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, 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.

SUPPLEMENTARY INFORMATION: This document proposes to take action on the 
State of Missouri Infrastructure SIP revision for the 2010 
SO<INF>2</INF> NAAQS. We have published a direct final rule approving 
the State's SIP revision(s) in the ``Rules and Regulations'' section of 
this Federal Register, because we view this as a noncontroversial 
action and anticipate no relevant adverse comment. We have explained 
our reasons for this action in the preamble to the direct final rule. 
If we receive no adverse comment, we will not take further action on 
this proposed rule. If we receive adverse comment, we will withdraw the 
direct final rule and it will not take effect. We would address all 
public comments in any subsequent final rule based on this proposed 
rule. We do not intend to institute a second comment period on this 
action. Any parties interested in commenting must do so at this time. 
For further information, please see the information provided in the 
ADDRESSES section of this document.
