Why is outdoor burning banned now? I've been doing it this way for years.

Even though humans have been burning wood since the beginning of time, scientists now know how hazardous wood smoke is to our health.
Laws have changed over the years to better protect our health and air quality.
In areas with a higher population density, the outdoor burning of yard debris has been banned completely. Burn barrels were banned over 20 years ago and in 1967 burning garbage was declared illegal.
Moisture meters can confirm firewood is seasoned properly and under 20% moisture content.
Air quality monitors help determine our air pollution impact to keep us on track.

It is just wood smoke why the concern?

Wood smoke is toxic and contains many of the same cancer-causing substances as cigarettes.
Short-term exposure can cause long-term health effects.
Smoldering wet material, like grass and leaves, creates heavy smoke that often settles at ground level.
A little smoke goes a long way and can travel for miles depending on the day.
As you may have experienced during the recent wildfire smoke episodes, you cannot just close the windows. The smoke will find its way into homes.


How am I supposed to control the smoke?

Dry material is key, whether burning yard debris, burning in a wood stove, fireplace or recreationally. The goal is a hot fire for complete combustion creating the least amount of smoke possible.

Choose another solution, instead of creating unnecessary air pollution.


The fire was out and only smoking.

Where there's smoke there's fire.
A smoldering fire creates ground level air pollution since there is little heat to help it rise.
Sometimes when the breeze is just right a smoking fire will relight.
Neighborhoods make for really good kindling and a fire can start with just one spark.

Burn it right and put it out completely before leaving tonight.


The fire department said I'm good to go.

The fire department will typically say a fire is okay, if it's well controlled and at no risk of escape.
The fire departments primary concern is fire safety, not air quality.
They should only be called in case of emergency.


A safe fire is not necessarily a legal fire.


Which burn permit do I need?

Let's start with where you live. Can you burn yard debris on your property? If the answer is yes, then it depends on what type of vegetative debris you need to dispose of. Even with a permit burn bans still apply.

Residential small debris fires related to property maintenance should only include DRY tree branches, and woody yard debris. The permit is for one fire under 10'x10'x6'. This is a single-day event that needs to be completely out before nightfall, with a free permit from the local county agency or the fire marshal. Instead of creating air pollution, choose to chip, compost, or recycle.

Did you clear trees from the property? Or have more than one pile of debris? Slash piles larger than 10ft x 10ft x 6ft, multi-day burning, or land clearing, require a site-specific permit from the county, SWCAA, or Department of Natural Resources (DNR), depending on location and any forest practices designation.


Why can't I burn pallets and other wood products?

Processed lumber may be coated with clear antifungal or pesticide agents which are toxic when burned. Demolition materials may contain contaminates including asbestos. Particle board and plywood contain formaldehyde, glues and other resins.

Chemistry by combustion poisons our air, water, and soil.


Can I burn manufactured fire logs?

Many manufactured fire starters and logs are made with ingredients that are illegal to burn and most are only to be used in an open-hearth fireplace or outdoors recreationally. Although they are legally sold in stores, read the instructions carefully and realize that when burned they give off a very distinctive acrid odor and the smoke has a blue-gray hue. SWCAA recommends sticking with seasoned firewood to avoid smoke and odor complaints in the neighborhood.


What's the difference between yard debris and seasoned firewood?

Time, preparation and moisture content. Properly seasoned firewood will contain under 20% moisture content when tested with a moisture meter.

Tip: Bark is naturally fire retardant and can have bite. Leave it out of the fire to ensure the cleanest burn possible. When the wood is split and seasoned properly, the bark should fall off naturally.


What are the setbacks for outdoor wood burning fires?

Overlapping fire safety and air quality setback regulations apply. Most fire safety regulations require a 25-foot setback from all combustibles for a recreational fire under 3'x3'. State air quality laws require 50-foot setbacks from structures, decks, and fences for all outdoor fires, regardless of type or size. SWCAA recommends converting recreational wood burning firepits to natural gas or propane to avoid potential smoke complaints.


Why are burn barrels banned?

Burn barrels were banned over 20 years ago by state law. When oxygen flow is restricted the incomplete combustion results in heavy smoke that can settle at ground level. Typically, barrels were used to burn garbage which is also illegal.

What fuel can I use to start the burn pile?

Nothing. The key is dry debris and oxygen. Propane burners, fans, and leaf blowers help add oxygen into the fire creating better combustion and less pollution. If the debris is wet or green, cover it from rainfall until the branches are free of leaves and dry enough to break clean.


Why are fireworks being banned?

In addition to the fire risk and noise complaints, fireworks cause extensive air pollution in a short amount of time. Fireworks leave metal particles, dangerous toxins, micro-litter, and harmful chemicals behind. The smoke can remain in the air for hours or days. Some of the toxins never fully decompose or disintegrate.

How can I find my neighbors address?

Locating an address may be easy when you live across the street. But when the target location is blocks away or behind your property, use your County GIS webpage, or other online maps to determine the address.

What are contrails?

Contrails or vapour trails are line-shaped clouds produced by aircraft engine exhaust or changes in air pressure. The combination of water vapor in aircraft engine exhaust and the low ambient temperatures that exist at high altitudes allows the formation of the trails. Visit the EPA for additional information on contrails from aircraft.


Who do I contact regarding paper mill complaints?

The Department of Ecology Industrial Section oversees refineries, smelters, paper mills, and chemical manufacturing plants.


Why do I need asbestos testing to take demolition materials to the dump?

Moving and separating materials at the transfer station can potentially expose the employees and public to asbestos. Learn more about demolition and renovation requirements.


What is the best air quality monitor?

There are many types, styles and unit measurements to choose from. A great place to start is the EPA Air Sensor Toolbox.
