The Air Pollution Program monitors the ambient air in San Antonio. The program Monitors for particulate matter 2.5 microns in size (PM2.5) and particulate matter 10 microns in size (PM10). These small particles could cause respiratory problems for small children, the elderly and the general public. The program also operates and maintains an ozone monitor located at Calaveras Lake for the Texas Commission on Environmental Quality (TCEQ).
In 2015 the San Antonio City Council passed ordinance
#2015-11-19-0967 requiring business facilities with air pollution
emissions to register with Metro Health and pay an annual registration
fee of $200.00 per facility. This registration process will help
identify local sources of ozone components and develop steps to lower
emissions and improve air quality for residents. Below you can find the registration form, a copy of the ordinance and a helpful Q&A.
