Residents in all other areas of Larimer County must obtain a General Open Burn Permit for mountain slash piles. The open burn period 'season' is from October 1 thru May 1, and is ALWAYS dependent upon favorable conditions existing (3 inches+ of snow on ground, light wind, daylight burning only) before ignition can occur. These General Open burn permit has a limit of 50 slash piles or less per year. Slash is defined as clean dry branches four inches or less in diameter, not containing other smoke producing materials. Applications will not be processed until one week before the start of the open burn period.
A Specialty Burn Permit must be obtained for conducting agricultural ditch burns, bon fires, or other fires containing non-prohibited materials. These are reviewed at the local fire department. Attaching digital photos for review of material types and specific safety guidelines is encouraged and may expedite the permitting process.
