From the NYS DEC website (All links leave SFD website) :

Open burning is the single greatest cause of wildfires in NYS. Since the spring burn ban was implemented in 2009, the number of wildfires has decreased by more than 40%. 

When you plan a fire, always check for fire danger in your area on DEC's online map (updated every week). Also, local governments may have stricter rules than NYS; your fire department will have information about local burning laws.

Prohibitions

Open burning is prohibited in NYS, with several exceptions:

• Camp fires or any other outdoor fires less than 3 feet in height and 4 feet in length, width or diameter are allowed.
• Small cooking fires are allowed.
• Ceremonial or celebratory bonfires are allowed. Disposal of flags or religious items in a small-sized fire is allowed, if it is not otherwise prohibited by law or regulation.
• Only charcoal or dry, clean, untreated or unpainted wood can be burned.
• Fires cannot be left unattended and must be fully extinguished.

In towns with a total population less than 20,000, you may burn tree limbs with attached leaves. The limbs must be less than 6 inches in diameter and 8 feet in length (also referred to as brush). However, this is not allowed from March 16 through May 14 due to the increased risk of wildfires. Burning loose leaves or leaf piles is illegal.

The practice of burning large piles of brush collected from local residents at town or county transfer sites is prohibited. The individual landowners in small towns may burn their brush on-site, as discussed above. Downed limbs and branches generated at a transfer site are also allowed to be burned on-site with the same restrictions. See Section 215.3 for a full list of exceptions.

Please note: While most firewood must be untreated, some firewood is heat treated (kiln dried) to control invasive insect species if it is to be transported over 50 miles. Heat treated firewood is not intended to be prohibited. However, the burning of chemically treated wood, such as pressure-treated lumber and plywood, is prohibited.

Camp Fire Safety

Camp fires with family and friends are great fun! To make your next camp fire safer and healthier, remember to:

• Check the fire danger map first to make sure it's safe to have a fire where you are.
• Watch this clip about camp fire safety on DEC's YouTube Channel.
• Avoid burning on windy days.
• Keep your camp fire less than 3 feet high and less than 4 feet wide.
• Keep flammable objects and debris at least 3 feet away from the fire.
• Never burn trash, including paper products, plastic, glass, and metal (like tin and aluminum cans).
• Burn only local firewood.
  • Burn only dry, plain wood - no pressure-treated lumber or plywood, and no painted or stained wood.
  • Untreated wood, split tree logs, and branches are recommended for camp fires.
  • Using heat-treated/kiln-dried wood can prevent the spread of invasive species.
• Never use fire accelerants such as kerosene, gasoline, or lighter fluid.
• Stay out of the smoke. The fire and its warmth can be pleasant for everyone, but inhaling smoke is unhealthy for you and for your pets.
• Keep water or a fire extinguisher nearby. Never leave your fire unattended.
• When you're finished with your fire, fully extinguish it. Stirring water or dirt into the remains of the fire can help.

We want you to fully enjoy your camp fire. Following these guidelines will help ensure a safer gathering.

Agricultural Uses

• Organic agricultural wastes may be burned on-site where they are grown or generated, including brush and wood produced by clearing fields and other activities.
• Fires must be located on contiguous agricultural land larger than 5 acres, and the materials capable of being fully burned within 24 hours.
• The burning of pesticides, plastics or other non-organic material is prohibited.
• The use of liquid petroleum fueled smudge pots to prevent frost damage to crops is allowed.
• Burning tires and other wastes for smudge is prohibited.
• Individual open fires to control plant and animal disease outbreaks are allowed as approved on a case-by-case by DEC, upon the request by the Commissioner of Agriculture and Markets.
• Prescribed burns - the burning of forest land to achieve a vegetative or wildlife management goal - can be performed, but only in accordance with DEC regulations. Check with your regional DEC office.

Municipal Uses

With some restrictions, fire training burning activities are allowed in accordance with guidance from NYS Division of Homeland Security and Emergency Services' Office of Fire Prevention and Control. The Fire Services Bureau may be reached at 518-474-6746. Towns, villages, cities, and counties can pass ordinances that are stricter than the open fires regulations. You should check with local authorities to find out if local law requires a permit or prohibits open fires. Explosives, or other dangerous contraband, may be burned on an emergency basis only by police or other public safety organizations.

Burning Trash is Against the Law

Burning trash is illegal statewide in all cases. Part 219 Incinerators prohibits burning trash in wood stoves, fireplaces, and outdoor wood boilers. It is unhealthy, un-neighborly, and unnecessary. It causes:

• serious health concerns and diseases,
• contaminated soil, and
• discomfort for others enjoying the outdoors or their own property.

The Problem with Burn Barrels

Burn barrels are a very dirty way to dispose of trash. They produce polluted air because fires in barrels are rarely hotter than 500°F. That's not hot enough for complete combustion, and incomplete combustion leads to harmful smoke and soot. DEC has lots of information about reducing, reusing, and recycling scrap materials, trash, and other waste you generate at home. Learn how to:

• manage fallen leaves without burning,
• properly dispose of household hazardous waste,
• compost your organic kitchen and garden waste, and
• produce less trash.

You can report polluters by calling the DEC hotline at 1-844-DEC-ECOs (1-844-332-3267).
