In 2012, the US Environmental Protection Agency (EPA) designated ten counties (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, Tarrant and Wise Counties) in North Central Texas as nonattainment for the pollutant ozone in accordance with the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS). These standards are designed to protect human and environmental health, and ground-level ozone is monitored and targeted for reductions due to its potentially harmful effects.
North Central Texas Council of Governments (NCTCOG) works in cooperation with federal, State, and local partners to ensure all air quality requirements are met. NCTCOG strives to achieve attainment of the ozone NAAQS as early as possible and contributes to a better quality of life for all North Texans.
Development of an air quality plan, known as the State Implementation Plan (SIP), is required for all nonattainment areas in order to demonstrate how ozone will be reduced to levels compliant with the NAAQS. The SIP for the Dallas-Fort Worth nonattainment area includes programs to get older cars off the road, technologies to clean up vehicles already on the road, and education programs so that citizens can do their part in improving air quality in North Texas.
