The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the State of Maryland. This SIP revision addresses Clean Air Act (CAA) requirements for enactment of a vehicle emissions inspection and maintenance (I/M) program in the Baltimore area of the state--where ambient air quality has been classified by EPA as "Moderate" or higher nonattainment of federal ozone national ambient air quality standards (NAAQS) established in 2008 (hereafter referred to as the 2008 ozone NAAQS). The requirements for moderate ozone nonattainment areas under the CAA require the state to demonstrate that they have adopted a basic I/M program (as defined by the CAA), or in the event an I/M program was previously enacted under a prior NAAQS or other CAA requirement, that the existing program meets all applicable federal requirements for a basic I/M program. Maryland's SIP revision that is the subject of this action pertains to CAA requirements for a basic I/M program in the Baltimore area for the 2008 ozone NAAQS. EPA's action to propose approval of this SIP revision is being taken under the applicable requirements of the CAA.
