## Abstract

EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Connecticut. The SIP revision addresses the provisions of the Clean Air Act that require each state to address emissions that may adversely affect another state's air quality through interstate transport. The Connecticut Department of Environmental Protection has adequately addressed the four distinct elements related to the impact of interstate transport of air pollutants. These include prohibiting significant contribution to downwind nonattainment of the National Ambient Air Quality Standards (NAAQS), interference with maintenance of the NAAQS, interference with plans in another state to prevent significant deterioration of air quality, and interference with efforts of other states to protect visibility. This action is being taken under the Clean Air Act.
