The Texas Commission on Environmental Quality (TCEQ) has issued
an Ozone Action Day for the Dallas-Fort Worth area for Wednesday,
July 22, 2026.
Atmospheric conditions are expected to be favorable for producing
high levels of ozone air pollution in the Dallas-Fort Worth area
on Wednesday. You can help prevent ozone pollution by sharing a
ride, walking, riding a bicycle, taking your lunch to work,
avoiding drive-through lanes, conserving energy, and keeping your
vehicle properly tuned.
