Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

On January 5, 2018, the Environmental Protection Agency (EPA) published in the Federal Register an advanced notice of proposed rulemaking (ANPR) specifically requesting early input and comments on the Agency's interpretation that air quality monitoring data from 2015-2017 support a finding that the Missouri Portion of the St. Louis nonattainment area attains the 1997 Annual National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM2.5). The notice also provided an evaluation of Missouri's 1997 Annual PM2.5 NAAQS maintenance plan, which includes the 2008 and 2025 NOX and PM2.5 motor vehicle emission budgets (MVEBs) and established the 2008 base year emissions inventory. EPA received no comments on the ANPR. EPA is now taking direct final action on three items, consistent with the ANPR. First, EPA is approving the state's request to redesignate the Missouri portion of the St. Louis MO-IL nonattainment area to attainment for the 1997 Annual PM2.5 NAAQS as the monitoring values demonstrate the area attains the standard. Second, EPA is approving the state implementation plan (SIP) revision containing a maintenance plan for the Missouri portion of the area including the motor vehicle emissions budget. Third, EPA is approving Missouri's 2008 base year emissions inventory in accordance with section 172(c)(3) of 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 Start Printed Page 38115comment, we will not take further action on this proposed rule.

SUPPLEMENTARY INFORMATION:

This document proposes to take action on the State of Missouri request to redesignate the Missouri portion of the St. Louis MO-IL nonattainment area to attainment for the 1997 Annual National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM2.5), and to approve the state's 2008 emissions inventory. 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.
