Notice is hereby given that the State of Connecticut has fulfilled the enforceable commitments it made to EPA to complete a mid- course review (MCR) assessing whether two one-hour ozone nonattainment areas are, or are not, making sufficient progress toward attainment of the one-hour ozone standard under the Clean Air Act (CAA). The two areas are the Connecticut portion of the New York-Northern New Jersey- Long Island 1-hour ozone nonattainment area, and the Greater Connecticut 1-hour ozone nonattainment area. EPA has reviewed the MCR documents submitted by Connecticut and has determined that Connecticut has met the commitment to perform these MCRs. EPA has sent a letter to Connecticut finding that their MCRs fulfill the commitment made by Connecticut in their 1-hour ozone attainment demonstrations.
