Q: Why are permits needed?
A: Open burning pollutes the air and poses a fire hazard, so the State and County regulate it to protect public health and the environment in our beautiful state. This pollution can cause serious short and long-term health problems, obscure visibility, and create odors impacting not only you but the health of your neighbors. Burning produces many harmful chemicals like carbon monoxide, hydrocarbons, formaldehyde, dioxins (a known carcinogen) and others that can irritate the eyes, nose and lungs.

Q: What CAN'T I burn?
A: Stumps, material that contains food wastes, plastic, coated or treated wood products, rubber, insulation, tires, car bodies, insulated wire, motor oil, aerosol cans, hazardous or toxic materials, or other materials that will produce substantial amounts of smoke and particulates are prohibited. You may not burn sawdust, slabs, chips, shavings, mill trim, or other wood products derived from wood processing, construction debris or buildings/structures for demolition purposes.
Q: Does slash pile size matter?
A: Yes! GCDNR recommends pile sizes not exceed 15' x 15' x 15' with a height that is at least equal to the width. This allows for good smoke management and for the pile to be easily consumed within a 12-hour period. To take advantage of the typical six-hour burn windows in our area, GCDNR recommends that piles be 10' in diameter and at least 8' high.
Q: Why can't I burn in a burn barrel?
A: Because it is against the law. Burn barrels are defined as incinerators by the Sates Air Quality Control Commission's Common Provisions Regulation. They do not combust efficiently due to lower air flow and temperatures.

A: Call the Grand County dispatch non-emergency number at 970-725-3311 to report smoke or an illegal open burn. The Daily Burn List on the GCDNR webpage lists all of the approved and permitted open burners in the County, as well as if it is a "burn day" or not.
