Open burn smoke permits

Due to continuing concerns surrounding the COVID-19 pandemic and its associated threat to people with heart and/or lung disease, the Colorado Department of Public Health and Environment highly discourages open burning at this time to reduce the potential for additional respiratory effects from smoke. If burning is absolutely necessary, please be mindful of nearby residents, especially those who may be suffering from cardiac or respiratory ailments.

Open burn smoke permits are for 50 or fewer piles to burn in the current calendar year and each pile is small enough that it will be out cold by sunset. Pile size is limited to 8'x8'x8' (512 cubic feet).Larger burns may require a smoke management permit.

If you wish to open burn in the following counties, please contact the local county health department for a permit:


All other counties require a state permit. Please apply below.
