Outdoor Burn Permits

Weld County is authorized by the State of Colorado Air Pollution Control Division to regulate burn permits and illegal burning complaints within Weld County in accordance with Air Quality Control Commission Regulations, Weld County Code, and Weld County Burn Permit Conditions as they pertain to air quality.

Fire Protection Districts oversee matters of fire safety and therefore a fire protection district’s determination regarding fire safety or fire code may supersede the issuance of an Open Burn Permit. Fire Protection Districts must be notified prior to burning and all local regulations and restrictions must be followed.

Rules and regulations regarding open burning as well as exemptions are listed below. Please review the information below prior to conducting any open burning. It is the responsibility of the property representative (owner/applicant) to be familiar with and follow all state, county, local, and fire protection district regulations and restrictions. In other words, learn before you burn.

Please keep in mind open burning is not a primary means of disposal. Please consider all other methods of disposal prior to burning, as the pollutants from open burns may be hazardous and have negative effects to local air quality.  Weld County offers a free landfill voucher, during select times of the year, good for up to one ton of waste at any of the landfills located in Weld County.  

Check the National Weather Service and Colorado Department of Public Health and Environment’s Open Burning Forecast pages for conditions. Open Burn Permits will not be issued and are suspended during Red Flag Warnings and Air Quality Advisories.

Do I need a burn permit?

If you are seeking to conduct a non-exempt open burn in Weld County, then you require either a general Open Burn Permit, issued through the Weld County Department of Public Health and Environment, or a Smoke Management Permit issued by the State of Colorado Air Pollution Control Division. If you determine the burn you are planning to conduct is non-exempt, continue to the “How do I obtain a burn permit” section. See list of exemptions below.

Keep in mind, an exemption is only from burn permitting requirements with the State Air Pollution Control Division. An exemption does not supersede rules of any other authority having jurisdiction, such as the local fire district, county, municipality, etc. Always check with your local fire district and follow all rules and regulations regarding any kind of burning.

Contact (970) 400-6415 or email burnpermits@weld.gov with questions. 

Exemptions:

  • Private residential (household) clean paper or cardboard.
  • Recreational or social fires:  Fires used for non-commercial cooking of food for human consumption or keeping warm for recreational/social purposes using appropriate fuel such as clean wood, paper, or cardboard. Typically, no larger than campfire size (approx. 2-3’ diameter) in a commercial pit/ ring or comparable containment (follow fire district rules/guidelines).
  • Fires used for instructional or training purposes as determined and authorized by the local fire district that would not otherwise be eligible for a Smoke Management Permit.
  • Safety flares used to signal danger to the public.
  • Agricultural open burning:  The open burning of cover vegetation for the purpose of preparing the soil for commercial crop production and commercial livestock pasture or maintenance of water conveyance structures related to agricultural operations, and other commercial agricultural cultivation purposes. See agricultural exemption memo.
    • Not all burns on agriculturally zoned land are considered agriculturally exempt burns. Typically, agriculturally exempt burns must fall into one of the following categories and usually be a broadcast burn. No other materials may be added:
  1. Irrigation or water conveyance/ditch burn.
  2. Burning of stubble from a commercial annual row crop.
  3. Burning commercial cropland vegetation for weed control.
  4. Burning to dispose of brush to improve forage for commercial livestock on ranches.

Even if exempt from obtaining a burn permit, all necessary safeguards should be utilized during exempt open burning to minimize any public health or welfare impacts. 

How do I get a burn permit?

Which burn permit do I need?

There are two types of burn permits for air quality purposes, the general Open Burn Permit and the state Smoke Management/Prescribed Fire Permit.
