Air Quality program

The Air Quality section includes the Air Pollution Control Registration program and other services that include operating and maintaining 25 air monitors that measure ozone and other air pollutants on a continual basis as required by Federal Clean Air Act (CAA).

The Air Pollution Control Registration program provides registration and educational consultations to large and small businesses to help reduce overall ozone levels and other air pollutants in the San Antonio community.  The program identifies businesses that emit air pollution and works with them on possible steps to lower emissions and improve air quality.  This program also responds to air quality complaints from residents and works with businesses to address those concerns.  Depending on the nature of the concern, the program will coordinate with state and local agencies.  


About the air quality program

The Air Quality Program, through a contract with the TCEQ, operates and maintains air pollution monitors at multiple sites throughout the San Antonio area.

Monitored pollutants include ozone, oxides of nitrogen (NOx), sulfur dioxide (SO2), and particulate matter (PM), which are criteria air pollutants whose limits have been set by the EPA in the national ambient air quality standards (NAAQS). Site photos, meta-data, and links to current measurements to the data being collected are available to the public through the GEOTAM website, maintained by the TCEQ. For continuous monitors (including ozone, NOx, SO2, and PM), data is automatically uploaded from the sites every 15 minutes to the Texas Air Monitoring Information System (TAMIS) which is available to SAMHD and the public through the TCEQ air pollution web pages. This data is also automatically uploaded to the EPA Air Now System, which is also available to the public.

There are four PM monitors for which SAMHD review and validate the data. Once finalized, the data is submitted via email to the TCEQ Data Management Section. For the rest of the monitors, TCEQ staff members review and validate the data. Once complete, all data is uploaded to the EPA Air Quality System (AQS) database by the TCEQ Data Management Section and is available to all members of the public.

The collected data is used in a variety of analyses, at the state and federal levels. The TCEQ has a daily air quality index report available through its website. Monitoring data is used to determine attainment with the National Ambient Air Quality Standards (NAAQS), which are set by the CAA, and is used by both state and federal authorities to make regulatory decisions. Using a variety of tools, including trend-line analysis and modeling, the monitoring network is reviewed by TCEQ every five years to ensure compliance with regulations and emerging pollution trends.

Outdoor Air Quality has improved since the 1990s, but many challenges remain in protecting Americans from air quality problems. Ground-level ozone, the main part of smog, and particle pollution are just two of the many threats to air quality and public health in the United States.
