ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R07-OAR-2015-0513; FRL-9934-95-Region 7]

Approval and Promulgation of Implementation Plans; State of 
Missouri, Limited Maintenance Plan for the St. Louis Nonclassifiable 
Maintenance Area for the 8-Hour Carbon Monoxide National Ambient Air 
Quality Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve revisions to the State Implementation Plan (SIP) submitted by 
the State of Missouri relating to the Ten Year Limited Maintenance Plan 
for the St. Louis area for the 8-Hour Carbon Monoxide (CO) National 
Ambient Air Quality Standard (NAAQS). On April 8, 2014, the Missouri 
Department of Natural Resources (MDNR) submitted to EPA a second 10-
year maintenance plan for the St. Louis area for the CO NAAQS. This 
maintenance plan addresses maintenance of the CO NAAQS for a second 10-
year period beyond the original redesignation. In accordance with the 
requirements of the Clean Air Act (CAA), EPA is approving the revision 
because the State adequately demonstrates that the St. Louis 
Maintenance area will maintain air quality standards for CO through the 
year 2022.

DATES: Comments on this proposed action must be received in writing by 
November 2, 2015.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R07-
OAR-2015-0513, by mail to Steven Brown, Environmental Protection 
Agency, Air Planning and Development Branch, 11201 Renner Boulevard, 
Lenexa, Kansas 66219. Comments may also be submitted electronically or 
through hand delivery/courier by following the detailed instructions in 
the ADDRESSES section of the direct final rule located in the rules 
section of this Federal Register.

FOR FURTHER INFORMATION CONTACT: Steven Brown, Environmental Protection 
Agency, Air Planning and Development Branch, 11201 Renner Boulevard, 
Lenexa, Kansas 66219 at 913-551-7718, or by email at 
brown.steven@epa.gov.

SUPPLEMENTARY INFORMATION: In the final rules section of the Federal 
Register, EPA is approving the state's SIP revision as a direct final 
rule without prior proposal because the Agency views this as a 
noncontroversial revision amendment and anticipates no relevant adverse 
comments to this action. 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 action, no further activity is 
contemplated in relation to this action. If EPA receives relevant 
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 action. EPA will not institute a second comment 
period on this action. Any parties interested in

[[Page 59705]]

commenting on this action should do so at this time. Please note that 
if EPA receives adverse comment on part of this rule and if that part 
can be severed from the remainder of the rule, EPA may adopt as final 
those parts 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.
