Abstract
Pursuant to the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the State of Maine. On February 18, 2020, the State submitted its 1997 ozone national ambient air quality standards (NAAQS) Limited Maintenance Plans (LMPs) for the Portland and Midcoast areas. EPA is approving the Portland and Midcoast LMPs because they provide for the maintenance of the 1997 ozone NAAQS through the end of the second 10-year portion of the maintenance period. The effect of this action will be to make certain commitments related to maintenance of the 1997 ozone NAAQS in the Portland and Midcoast maintenance areas part of the Maine SIP and therefore federally enforceable.
