Texas to Expand Vehicle Inspection and Maintenance Requirements in San Antonio Area

The state of Texas will be expanding on its vehicle inspection and maintenance requirements in Bexar County, according to a press release from the U.S. Environmental Protection Agency.

In 2022, the EPA reclassified the San Antonio area from marginal to moderate nonattainment of the 2015 ozone standard of 0.07 parts per million, or 70 parts per billion, requiring Texas to revise part of its State Implementation Plan and reduce emissions from vehicles that contribute to the formation of ozone.

The approved revisions will require an expansion of Texas’ existing inspection and maintenance program, and will have to be implemented in Bexar County by Nov. 7, 2026. Currently, the program requires annual on-board diagnostics testing of gasoline-powered vehicles between 2–24 years old in Bexar County.

“The Clean Air Act lays the groundwork for one of EPA’s most important core responsibilities—to improve air quality for all Americans,” said Regional Administrator Scott Mason. “EPA will continue to work with the state of Texas to develop sensible plans for addressing air pollution and helping San Antonio meet air quality standards.”
