Open Burn Regulations

What is open burning?

Open burning is the burning of materials wherein products of combustion are emitted directly into the ambient air without passing through a stack or chimney from an enclosed chamber. For the purpose of this definition, a chamber shall be regarded as enclosed when, during the time combustion occurs, only apertures, ducts, stacks, flues or chimneys necessary to provide combustion air and permit the escape of exhaust gas are open. Generally, anytime you light a fire outdoors, you are open burning. Examples of these types of fires include open fire pits, burn barrels, burn piles, and ditch burns.  
 
Before applying for an open burn permit, we encourage you to choose an alternative method of disposing of the materials. Please consider reducing, reusing, recycling, composting, or disposing at a landfill.
 
Who regulates open burning?

In Colorado, open burning is regulated at both the state and local levels. Before applying for a permit from us you should first obtain the appropriate permit from the state or county (IFC 307.2.1).
  After obtaining the appropriate state or county permit, fill out our permit application here (IFC 105.6 and 307.2), and email it to openburning@brightonfire.org . Please be aware that your permit must be submitted to us no later than 4:00 PM the day before you would like to burn. If you plan to burn on the weekend, this application must be submitted by 4:00 PM on Friday.

Once our permit has been issued, you must call us at 303-659-4101 before 10:00 am on the day of each burn or by 4:00 PM on Friday for weekend days. Please be prepared to give us the following information:

Can I burn in a burn barrel?
 
No, burn barrels are defined as incinerators using the definition given in the Air Quality Control Commission Common Provisions Regulation. Incinerators require Construction Permits and are subject to federal and state testing requirements and regulations. Incinerators are required by the EPA to have pollution control systems that reduce emissions. Burn barrels also do not combust efficiently, resulting in limited oxygen and lower temperatures that create smoke, odors and a variety of toxic pollutants like dioxins. Dioxins are known carcinogens and can increase the risk of both short-term and long-term health problems.
 
What about at my house? Do I need a permit to use my outdoor fire place or pit?
 
No, as long as they meet the definitions below for a portable outdoor fireplace or recreational fire.
 
My neighbor is burning in their backyard. Should I call BFRD?
 
As long as your neighbor is following the rules for portable outdoor fireplaces or recreational fires (see definitions below) they are not in violation of the fire code, we encourage you to work through the situation with your neighbor. We understand that this may be frustrating, however when we get dispatched to fires that follow the rules valuable resources are not available for emergencies that may occur. Below is a checklist to help you determine if your neighbor is following the rules and taking the appropriate safety measures:
 
  • All instructions, suggestions and safety precautions provided by the device manufacturer are followed
  • Prohibited items and materials are not being burned (see above list of materials)
  • The open burn is attended at all times until fully extinguished
  • The local wind speeds do not exceed 10 mph
  • A water supply capable of extinguishing the material is readily available on-site 
  • There is not a “red flag warning”
    • Weld County - Zone 243
    • Adams County - Zone 240
  • Recreational fire is not within 25 feet of combustible materials or structures
