ENVIRONMENTAL PROTECTION AGENCY

40 CFR Parts 52, 62 and 70

[EPA-R07-OAR-2015-0006; FRL 9923-67-Region 7]


Approval and Promulgation of Air Quality Implementation Plans, 
State Plans for Designated Facilities and Pollutants, and Operating 
Permits Program; State of Missouri

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve revisions to the State Implementation Plan (SIP) and the 
operating permits program for the State of Missouri which were received 
on November 6, 2013, November 20, 2014, March 27, 2014, July 7, 2014, 
and July 14, 2014. The revisions submitted by the state include 
amendments to rules relating to reference methods, definitions and 
common reference tables, ambient air quality standards, and a rule 
rescission related to air quality control measures for sources 
clustered in small land areas. Many of the revisions are administrative 
in nature and either incorporate by reference or update state rules to 
match Federal regulations. Some are more substantive, but are non-
controversial. In addition, they provide more clarity for the regulated 
public. This direct final action will amend the SIP to include revised 
regulations which will then be more consistent with Federal 
regulations. These revisions do not have an adverse effect on air 
quality. EPA's proposed approval of these rule revisions is being done 
in accordance with the requirements of the Clean Air Act (CAA).

DATES: Comments on this proposed action must be received in writing by 
April 3, 2015.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R07-
OAR-2015-0006, by mail to Amy Bhesania, 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: Amy Bhesania, Environmental Protection 
Agency, Air Planning and Development Branch, 11201 Renner Boulevard, 
Lenexa, Kansas 66219 at (913) 551-7147, or by email at

SUPPLEMENTARY INFORMATION: EPA is proposing to approve revisions to the 
State Implementation Plan (SIP), the 40 CFR part 62 state plans 
(111(d)), and the 40 CFR part 70 operating permits program, for the 
State of Missouri's requests to amend the following rules:

1. 10 CSR 10-6.040, Reference Methods, received November 6, 2013.
2. 10 CSR 10-6.040, Reference Methods, received November 20, 2014.
3. 10 CSR 10-6.020, Definitions and Common Reference Tables, 
received March 27, 2014.
4. 10 CSR 10-5.240, Additional Air Quality Control Measures May be 
Required When Sources are Clustered in a Small Land Area, received 
July 7, 2014.
5. 10 CSR 10-6.010, Air Quality Standards, received July 14, 2014.

    The revisions submitted by the state include revisions to update 
standards and reference methods, to clarify, add or amend definitions 
and reference tables, to rescind an outdated rule, and to update and 
clarify ambient air quality standards. For more information on the 
state's submissions, specific revisions to each rule and EPA's review 
of the revisions, see the Technical Support Document (TSD) that is a 
part of this docket.
    In the final rules section of this 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 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.
