Public Works | Air Polution
This program reviews all permit applications received by the Texas Commission on Environmental Quality (TCEQ), for construction of new facilities and modification of existing operations that have the potential to emit air contaminants. All facilities in the city that have the potential to make a significant contribution to air pollution are inspected annually.
Program staff responds to citizen requests about outdoor smoke, dust, mists, fumes and odors. Smoke from fireplaces and indoor air quality are not regulated. The program also operates an ambient air monitoring network, which measures the level of pollution caused by six major pollutants. This information is used to determine the level of compliance with current ambient air standards and to issue the daily Air Quality Index. To view today’s Air Quality Index, go to this website’s Home page and look at “Today’s Air Quality”. For information about program services, please call (214) 948-4435.
Ozone is formed by the chemical reaction of heat and sunlight on Volatile Organic Compounds (VOC) and Nitrogen Oxides (NOx) at ground level. Intensified reactions are a summertime problem due to high temperatures, minimal wind, sunlight, vehicle exhaust, and other air pollution. Ozone can cause health problems depending on length and frequency of exposure and level of concentrations. The ozone season in Dallas is from May through October.
Citizens may access www.dallasair.org, North Texas Clean Air Coalition, the North Central Texas Council of Governments, EPA, or TCEQ for additional information and steps individuals can take to reduce ozone and improve air quality.
