Certain brands and models of burning devices are exempt from the state regulation that bans indoor burning in the seven-county Denver-metro area on air quality Action Days. These exempt burning devices have been approved by Colorado or certified by the U.S. Environmental Protection Agency and are designed to emit low levels of pollution.
If indoor burning is your only source of heat, then even an uncertified or unapproved device may be exempt and allowed for use. For more information call Hugh Davidson at the Air Pollution Control Division at (303) 692-3157.
Burning artificial, manufactured or compressed wood logs in uncertified devices is also a violation. The regulation prohibits the use of uncertified devices, not fuels, on air quality Action Days.
It is illegal to install uncertified burning devices in the seven-county Denver-metro area. It is also illegal to sell new or used uncertified burning devices in this region.
