Under a delegation of authority from the Colorado Department of Public Health and Environment, Grand County allows large-scale open burning during the winter months only and only during favorable air quality conditions.  Our program only applies to private property owners and slash piles, not trash or buildings. The opening and closing of burn season depends upon weather and the presence of sufficient, permanent snow pack throughout most of the county. As a result, start and end dates vary from year to year, but generally the burn season runs from late November through March. Grand County Division of Natural Resources begins issuing open burn permits in mid-October and opens the season when there is sufficient snowpack countywide. These permits are valid for an entire burn season and expire on or around April 1, whenever the snowpack is not sufficient for safe burning. If you have questions or for more information, please call our office at 970-887-0745.

The general conditions of the permit are as follows:

• Approval must be given by the Division of Natural Resources for ignition on a daily basis during the burn season.
• Inspection of piles may be required by the division.
• The burn area will be attended at all times while flames are present.
• The permit must be on-site with the individual supervising the burn.
• Hazardous or toxic materials or construction debris cannot be burned in an open burn pile - only untreated wood is permitted in a burn pile.
• It is recommended that pile sizes not be larger than 15 ft x 15 ft x 10 ft to allow for maximum opportunity to burn.
• Piles and material in piles should be dried for a minimum of one year prior to ignition. Large diameter material (greater than 6 inches in diameter) cannot exceed 20% of the pile density.
• Stumps and/or dirt are not allowed in open burn piles and piles containing dirt / stumps cannot be permitted.
• Homeowner association (HOA) regulations take primacy over county regulations.
• Any of the above conditions not met shall render the burn permit null and void and enforcement action by Grand County and possibly the Colorado Department of Public Health and Environment can result.
• Burn season will have closures on Thanksgiving Day, Christmas Day & New Years Day.
