Most outdoor burning in unincorporated Larimer County requires
a permit signed by both the Fire Department and
the Department of Health and Environment. The fire department
evaluates applications for potential fire safety
issues, while the health department evaluates
applications for air quality issues that can impact
human health. For example, open burning
releases fine particulates that can aggravate
chronic lung diseases and carbon monoxide that
can prevent the transport of oxygen in the blood.
Open burning in Larimer County is regulated by
the Colorado Department of Public Health and
Environment/Air Pollution Control Division and
Larimer County Department of Health and
Environment under Colorado Air Quality Control
Commission's Regulation One. Open burning
without a permit is illegal and can result in fines
of up to $10,000 per day.
Prohibited Materials
Routine yard and garden clean-up waste
