Approval and Promulgation of Air Quality Implementation Plans; State of Missouri; Emissions Inventory and Emissions Statement for the Missouri Portion of the St. Louis MO-IL Ozone Nonattainment Area

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) for the state of Missouri. The revisions address base year Emissions Inventory (EI) and emissions statement requirements of the Clean Air Act (CAA) for the Missouri portion of the St. Louis marginal ozone nonattainment area (“St. Louis area”). The Missouri counties comprising the St. Louis area are Franklin, Jefferson, St. Charles, and St. Louis along with the City of St. Louis. EPA is proposing to approve the SIP revisions because they satisfy the CAA section 182 requirements for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS). EPA is proposing the revisions pursuant to section 110 and part D of the CAA and EPA's regulations. EPA will consider and take action on the Illinois submission for its portion of the St. Louis area in a separate action.

DATES:

Comments on this proposed action must be received in writing by March 28, 2016.

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 If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed action.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