2023-00368. Air Plan Approval; Michigan; Base Year Emissions Inventory and Emissions Statement Rule for the 2015 Ozone Standard

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve, under the Clean Air Act (CAA), a request submitted by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) on December 18, 2020, to revise the Michigan State Implementation Plan (SIP). EGLE's submittal addresses the emissions inventory and emissions statement requirements for the Allegan County, Berrien County, Detroit (Livingston, Macomb, Monroe, Oakland, St. Clair, Washtenaw, and Wayne Counties) and Muskegon County nonattainment areas under the 2015 ozone National Ambient Air Quality Standard (NAAQS or standard). The CAA requires states to develop and submit, as SIP revisions, emission inventories for all ozone nonattainment areas. In this action, EPA is proposing to approve EGLE's emissions inventories for the Allegan County, Berrien County, and Muskegon County nonattainment areas under the 2015 ozone NAAQS and the removal of the repealed Act 348, Section 14a. EPA approved the portions of EGLE's December 18, 2020, submittal pertaining to the certification of EGLE's stationary annual emissions statement regulation and emissions inventories for the Detroit nonattainment area under the 2015 ozone NAAQS in a separate action on July 6, 2022.

SUPPLEMENTARY INFORMATION:

In the Final Rules section of this Federal Register , EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. 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 rule, no further activity is contemplated. If EPA receives such comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions 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 .
