Abstract
The Environmental Protection Agency (EPA) is partially approving and partially disapproving elements of a State Implementation Plan (SIP) submission from Michigan regarding the infrastructure requirements of section 110 of the Clean Air Act (CAA) for the 2015 ozone National Ambient Air Quality Standards (NAAQS). 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. The disapproval portion of this action does not begin a new Federal Implementation Plan (FIP) clock, because the FIPs are already in place. EPA proposed to approve this action on Friday, July 2, 2021 and received no adverse comments.
