Enforcement and reporting violations
Report suspected violations:
Air Quality Control Commission Regulation 4 prohibits the use of uncertified devices on air quality Action Days during the annual high pollution season (November-March). Uncertified devices include traditional fireplaces and any uncertified stove or insert.
This is a recorded message line operated by the Air Pollution Control Division. We'll typically refer the call to the local municipality in which the violation occurred.
Most local municipalities in the seven-county metro Denver area enforce indoor burning bans on air quality Action Days through local ordinances.
Enforcement actions typically start with a warning letter to the offender. Repeat violators may face fines ranging from $100 to $15,000 per day of violation.
