Ozone Planning Efforts
Connecticut has persistently been designated nonattainment for national ambient air quality standards for ozone. Nonattainment is mainly due to transport of pollutants from the New York metropolitan area reacting to form ozone as they travel across Connecticut. Connecticut DEEP has been working with neighboring states and the EPA to reduce local and regional emissions that cause ozone. These emissions reductions strategies are documented below.
