Federal Air Rules for Indian Reservations Fact Sheet: Orchard & Vineyard Burning
Why do farmers tear out existing orchards and vineyards?
Orchardists change varieties of fruit and farming techniques to remain competitive in the market. This requires the orchardists to tear out existing blocks of orchards and vineyards to prepare for replanting.
What happens to the material that is removed?
Several methods can be used to dispose of woody material from orchard and vineyard pruning and tear outs, including burning, chipping, shredding, grinding, composting or use as hog fuel.
Although burning may appear to be the easiest way to dispose of vegetation, the use of alternative disposal methods can result in cleaner air for our families and community.
What are the health effects related to burning orchard and vineyard material?
Smoke is made up of a complex mixture of gases and fine particles produced when wood and other organic matter burn. The biggest health threat from smoke comes from fine particles. These microscopic particles can get into your eyes and respiratory system, where they can cause health problems such as burning eyes, runny nose, and illnesses such as bronchitis. Fine particles can also aggravate asthma and chronic heart and lung diseases—and are linked to premature deaths in people with these chronic conditions.
Who is most affected by this type of air pollution?
Elders, children, pregnant matter. breathing smoke and particulate asthma) are most at risk from or respiratory diseases (like women and people with heartWhat rules apply to burning orchard and
Open burning of orchard and vineyard material is regulated by the Federal Air Rules for Indian Reservations in Idaho, Oregon, and Washington (FARR). FARR open burning rules must be adhered to when burning orchard or vineyard material:
- During a burn ban, open burning is not allowed. EPA may declare a burn ban whenever air quality concentrations approach, or are predicted to approach, the heath standards for particulate matter. Please call the FARR Hotline at 1-800424-4EPA or check the FARR website
How can I burn more cleanly and safely?
Keep it Dry:Make sure the materials are as dry as possible and free from dirt. Three weeks is recommended for drying for prunings and small branches, and at least six weeks is recommended for drying for large branches and stumps.
Keep it Hot:Build and maintain the fire as hot as possible. Burning at low temperatures creates smoke as a result of incomplete combustion. Heat and ignite the entire pile as quickly as possible with a propane torch or other commercial lighting device.
Oxygen:Stack your starter pile of brush and wood as tightly as possible, but make sure it has enough air circulating throughout. Brush and wood require plenty of air to burn efficiently. Smaller pieces will burn more quickly than larger chunks. Carbon monoxide, volatile organic compounds and soot particles are produced when there is not enough oxygen available.
Use the Right Material:Only burn natural vegetation. Add material after the starter pile is fully engulfed. Once the fire is started, feed it continuously. Avoid pushing dirt into the pile with the pruning or tear out material.
Manage the Fire:Make several small diameter, tall piles rather than one large, sprawling pile. Keep the piles small enough to control the fire and prevent escape. You must have fire suppression equipment and water available.
Don’t leave your fire unattended:Unattended fires are a hazard and you need to be on hand to maintain a hot fire. Do not walk away until the fire is out and cool.
Manage the Smoke:Light a small test fire before starting your fire to check the direction of the smoke plume and ventilation. Be sure the plume is blowing away from neighbors, roads, schools and other sensitive places to prevent smoke impacts to surrounding people and places. If a burn has the potential to cause visibility hazards on roadways, contact the local transportation agency prior to burning for applicable traffic control requirements.
