SAN ANTONIO, TX (May 17, 2020) –  The Texas Commission on Environmental Quality (TCEQ) has issued the Third Ozone Action Day of the year for the San Antonio area for tomorrow Monday, May 18, 2020.

Atmospheric conditions are expected to be favorable for producing high levels of ozone air pollution in the San Antonio area tomorrow.  On Ozone Action Days, young children, the elderly, and those with respiratory problems, such as asthma, emphysema, and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities. If you have asthma or difficulty breathing, please stay indoors. With COVID-19 in our community, it is critical for San Antonio residents to stay home, work safe and limit trips outside their home to those that are absolutely essential.

Ground level ozone is Ozone is formed when Oxides of Nitrogen (NOx) and Volatile Organic Compounds (VOCs) combine and are exposed to sunlight and heat. These chemicals come from various sources to include power plants, off-road equipment and vehicle emissions.

To help keep the air healthy, residents and business are encouraged to practice certain pollution-reducing activities such as:

  • Refueling cars and trucks after 6:00 p.m.
  • Turning your vehicle off instead of idling
  • Setting air conditioner thermostats to a higher temperature if possible and use ceiling fans instead to help cool your home if available
  • Combining essential errands to reduce trips
