Longer days and rising temperatures mark the return of spring and the start of ozone season in North Texas.
With ozone season officially underway, the North Central Texas Council of Governments (NCTCOG) is kicking off community air quality outreach efforts across the region.
On Saturday, March 28, NCTCOG will take part in Earth Party at Trinity Park Pavilion 4 from 11 a.m. to 1 p.m. Hosted by Keep Fort Worth Beautiful, the event follows the 2026 Cowtown Great American Cleanup and is aimed at bringing together residents to celebrate caring for the community. Attendees will have the opportunity to learn more about local air quality initiatives and simple steps they can take to make a difference.
Additional outreach events are planned throughout April, providing more opportunities for North Texans to celebrate and learn more about cleaner air.
These events coincide with a critical time for the region. Ozone season runs annually from March 1 through Nov. 30. With higher temperatures, sunlight and heat interact with precursor pollutants Volatile Organic Compounds (VOCs) and Nitrogen Oxides (NOx), creating favorable conditions for the formation of ground-level ozone, a harmful air pollutant that negatively affects air quality and public health.
The 2025 season ended with a design value of 83 ppb at two regulatory monitors in Collin (Frisco) and Tarrant (Fort Worth Northwest) counties. As a result, the region remains in nonattainment of both the 2008 (75ppb) and 2015 (70ppb) National Ambient Air Quality Standards for ozone.
Dallas-Fort Worth is currently classified as a “severe” nonattainment zone under the Environmental Protection Agency’s (EPA) 2008 ozone standard and a “serious” nonattainment zone under the 2015 standard, with a deadline to reach compliance by 2027.
Improving air quality is a shared responsibility. NCTCOG offers various online resources to help individuals, businesses and local governments stay informed and take action. The 2025 Air Quality Handbook provides a full breakdown of the region's air quality and air quality initiatives. Learn more at NCTCOG.org/trans/quality/air.
Staying informed about daily air quality initiatives and strategies help individuals and businesses reduce emissions by taking small, everyday actions. Residents can sign up for air quality alerts at AirNorthTexas.org/sign-up-for-alerts.
