All vehicles on military installations in emission counties are required to be in compliance with the emission testing program.
- This includes vehicles registered in Texas and vehicles registered in all other states.
- If your military installation is located in Brazoria, Collin, Dallas, Denton, El Paso, Ellis, Fort Bend, Galveston, Harris, Johnson, Kaufman, Montgomery, Parker, Rockwall, Tarrant, Travis, and Williamson county, your vehicle is subject to the I/M testing guidelines.
- Background: The Clean Air Act Amendments of 1990 (CAAA) enacted new regulatory requirements for motor vehicles operating in ozone and carbon monoxide non-attainment areas. In the CAA, Congress imposed additional requirements on the Federal government to assure that government and Federal employee vehicles operated on Federal facilities located within a state motor vehicle I/M program area shall be tested, regardless of whether the vehicles are registered in the state or local I/M area. The program applies to government owned/leased vehicles ((CAA Section 118(c)) and employee owned/leased vehicles (CAA Section 118(d)) operated on federal facilities more than 60 days per year, regardless of the state where the vehicle is registered. Military tactical vehicles are exempt.
