2017-21525. Approval of Missouri Air Quality Implementation Plans; Infrastructure SIP Requirements for the 2008 Ozone 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 2008 Ozone 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-2015-0356, to https://www.regulations.gov. Follow the online instructions for submitting comments.

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.

SUPPLEMENTARY INFORMATION:

This document proposes to take action on the State of Missouri Infrastructure SIP revision for the 2008 Ozone 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.
