- Emissions Technical Centers identify and investigate instances of vehicle tampering and pursue enforcement activities when appropriate.
- These multifunctional facilities provide a range of customer service and field services to help vehicle owners and the repair industry meet emission testing requirements.
- Evaluating the impact of the Colorado emissions inspection program and real-world emissions reductions.
- Collaborating to design and implement new versions of software used throughout the program.
The Department of Revenue administers the day-to-day operations, including:
