What the agency says

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Connecticut. On May 9, 2023, and supplemented on February 21, 2024, the State submitted a Limited Maintenance Plan (LMP) for the 2006 24-hour PM<INF>2.5</INF> National Ambient Air Quality Standard (NAAQS) for New Haven and Fairfield Counties (New Haven-Fairfield). This revision provides for the maintenance of the 2006 24-hour PM<INF>2.5</INF> NAAQS through the end of the second 10-year portion of the maintenance period. Additionally, EPA finds the LMP to be adequate since it meets the appropriate transportation conformity requirements. The intended effect of this action is to approve Connecticut's LMP for the 2006 24- hour PM<INF>2.5</INF> NAAQS for the New Haven- Fairfield maintenance area into the Connecticut SIP. This action is being taken in accordance with the Clean Air Act.
