CDPHE operates emissions technical centers throughout the Denver Metro and North Front Range areas. These are multifunction facilities that conduct a variety of customer service and field activities to help vehicle owners and the repair industry meet emission requirements.
Emissions technical centers are especially helpful if your vehicle has already failed multiple emissions inspections. Their technicians are experts in identifying emissions-related problems, but they do not make any repairs.
Emissions technical centers serve motorists, independent and franchised auto dealers, automotive repair technicians, diesel fleet owners and operators, petroleum marketers, alternative-fuel vehicle converters and consumers, and the Colorado Department of Revenue.
Emissions technical centers also provide training and certification for repair technicians and emissions inspectors, and inspect to support the Diesel Emissions Control Program and the Oxygenated Gasoline Program.
Emissions technical centers evaluate vehicles by appointment only. Please contact the center nearest you to make an appointment:
