Regional Effort

The SA-BC MPO study area currently has several Continuous Air Quality Monitoring Systems (CAMS) that record ozone levels daily. EPA utilizes a three-year rolling average to determine our air quality status. The regulatory ozone CAMS include the San Antonio Northwest (C23), Camp Bullis (C58), Calaveras Lake (C59), CPS Pecan Valley (C678) and the CPS Heritage Middle School (C622). In addition, the Alamo Area Council of Governments (AACOG) operates six non-regulatory ozone monitoring sites across the region during the ozone season.
In order to remain in attainment, the area will need a rolling three-year, fourth highest annual average of no greater than 75 parts per billion (ppb)
