Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve revisions to the State Implementation Plan (SIP) for the State of Missouri submitted on October 17, 2013. These revisions remove definitions that were in this rule but have been moved to the state's general definitions rule. The revisions also add text and corrects a wording error found in the rule. EPA's 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 October 16, 2015.

SUPPLEMENTARY INFORMATION:

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 If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed action.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.
