Nonattainment Information

San Antonio and Bexar County are in exceedance of federally mandated ground-level ozone standards and effectively have until the end of 2020 to attain the standard or face stricter regulations. The most recent measurements for 2018 show the region just 2 parts per billion (ppb) above the standard of 70 ppb. This number will be the first of three years averaged to determine whether San Antonio is in attainment by 2020.

Despite significant ozone level improvements over the past decades, continued focus on air quality is needed to reach the health-based standard established by the Environmental Protection Agency. Local stakeholders are working closely together to prioritize action steps to reduce emissions that contribute to ground-level ozone and minimize pollution exposure. Partners include Bexar County, Alamo Area Council of Governments, Alamo Area Metropolitan Planning Organization, VIA Metropolitan Transit, CPS Energy, Joint Base San Antonio (JBSA), independent school districts and other community-based organizations.

Funding opportunities for emissions-reducing opportunities are available through the Texas Commission on Environmental Quality (TCEQ.) In addition, these TCEQ resources are available:
