Thurston County Burn Ban: ORCAA Stages, Permits, and Penalties

A Thurston County burn ban can come from either of two agencies, and the type of ban in effect determines exactly what you can burn. The Olympic Region Clean Air Agency (ORCAA) declares air quality burn bans, usually in winter, when fine particulate pollution builds up. The Thurston County Fire Marshal declares fire safety burn bans, usually in summer, when dry vegetation raises the wildfire risk. Both carry civil penalties of up to $14,915 per day, and the two types restrict different activities.¹

Before lighting anything, confirm which ban (if any) is active. That single fact tells you whether your wood stove, fire pit, or yard debris pile is legal today.

Air Quality Burn Bans From ORCAA

ORCAA monitors PM2.5 pollution across Thurston County and issues air quality bans in two escalating stages. These almost always happen in winter, when cold, stagnant air traps wood smoke near the ground.

Stage 1

A Stage 1 ban is called when forecasts show PM2.5 is likely to exceed 35 micrograms per cubic meter on a 24-hour average within 48 hours.² While it’s in effect:

Uncertified wood stoves and fireplaces cannot be used unless wood is your only source of heat and you have previously notified ORCAA.
Certified wood stoves may still operate, but no visible smoke is allowed beyond a 20-minute start-up period.
All outdoor burning is prohibited, including yard waste, campfires, fire pits, chimineas, and fire kettles.³

Stage 2

A Stage 2 ban follows if Stage 1 restrictions haven’t turned the pollution trend around, PM2.5 has reached 25 micrograms per cubic meter on a 24-hour average, and no improvement is forecast for at least another 24 hours.² At Stage 2:

All wood-burning devices are banned, including EPA-certified stoves, pellet stoves, and fireplace inserts, unless wood is your only source of heat.
All outdoor fires remain prohibited, with no exceptions for recreational burning.
Gas and propane appliances are still allowed. Furnaces, electric heat, and gas fireplaces are the intended fallback.³

Fire Safety Burn Bans From the County Fire Marshal

Fire safety bans exist to reduce wildfire risk, not air pollution. The Thurston County Fire Marshal declares them after consulting the County Manager, the Board of County Commissioners, the Director of Emergency Services, DNR, and ORCAA.⁴ The usual trigger is DNR raising its fire risk rating to “high” for public lands in the region.⁵

These bans primarily shut down outdoor burning: yard waste, land-clearing fires, and debris burns. Recreational campfires may still be permitted during a moderate fire safety ban, but they are typically the first thing cut when conditions worsen. The ban stays in place until meaningful rainfall or sustained moisture brings the fire danger back down.

Rules can differ between unincorporated county land and areas inside city limits, so check your specific jurisdiction if you live near a boundary.

Certified vs. Uncertified Wood Stoves

Whether your wood stove or fireplace can operate during a Stage 1 ban hinges on certification. Under Washington law, a certified device meets EPA emissions standards or has been certified by the state Department of Ecology.² Current federal standards cap emissions from new stoves at 2.0 grams per hour with crib wood, or 2.5 grams per hour with cord wood.⁶

Check the back of your stove. A certification label means it counts as certified. Older stoves without a label are uncertified, and they are the first devices restricted during a Stage 1 ban. During Stage 2, certification stops mattering because all solid-fuel devices are barred. The sole-source-of-heat exception applies at both stages, but Stage 1 also requires that you have notified ORCAA in advance.³

Burning When No Ban Is Active

Even outside ban periods, outdoor burning in Thurston County still requires a permit, and the rules carry the same fines if you ignore them.

Residential Yard Waste Permits

ORCAA issues residential yard waste burn permits for properties in unincorporated Thurston County only. Outdoor burning is not allowed inside any city limits or urban growth areas at any time. You can apply through ORCAA’s online permit request form. The core requirements:¹

Burn only natural vegetation grown on the property. Garbage, construction debris, and treated wood are illegal to burn.
Daylight hours only. Do not light a fire when wind exceeds 5 mph, and extinguish immediately if wind reaches 10 mph.
Pile no more than 10 feet wide or 5 feet high, and only one fire at a time per property.
Setbacks: at least 50 feet from any structure or standing timber, 10 feet from property lines, and 500 feet from forest or land-clearing debris piles.
A shovel and a water-charged hose must be on site and ready. Two full 5-gallon buckets of water can substitute for the hose.
Someone must stay with the fire until there is no flame and no smoke remaining.

Burn barrels are illegal everywhere in Washington. Your permit becomes invalid the moment any burn ban takes effect, whether air quality or fire safety.¹

DNR Permits for DNR-Protected Land

If your property sits on land under DNR fire protection, you need a separate DNR burning permit in addition to any ORCAA requirements. DNR may inspect the site first, attach conditions, and revoke or postpone the permit if conditions change.⁷ No agency can issue any burning permit while an impaired air quality stage or air pollution episode is in effect.⁸

Recreational Fires and Fire Pits

Recreational fires on your property generally do not require an ORCAA burn permit if they are no larger than 3 feet in diameter and fueled only by clean, dry firewood or charcoal. ORCAA recommends contacting your local fire department to confirm any additional local rules.⁹

During any air quality burn ban, Stage 1 or Stage 2, all recreational fires are prohibited. That covers backyard fire pits, chimineas, and fire kettles. Gas and propane fire features are not affected by air quality bans and remain legal at both stages.³ During a fire safety ban, recreational fires may or may not be restricted depending on severity, so read the current ban notice.

How to Check Current Burn Status

Conditions change quickly. Verify status through official sources before lighting.

ORCAA’s website (orcaa.org) posts current air quality readings and active air quality burn ban notices for Thurston County.
The Thurston County website (thurstoncountywa.gov) publishes Fire Marshal declarations when a fire safety ban is enacted or lifted.⁴
Local fire districts post signage at their stations and share updates through social media as fire danger ratings change.

ORCAA specifically asks that you check its site immediately before igniting any permitted burn pile, even if no ban was active when your permit was issued.¹

Penalties for Illegal Burning

ORCAA can assess civil penalties up to $14,915 per day for each violation, and each day the violation continues counts as a separate offense.¹ Burning prohibited materials such as garbage or construction debris carries that same maximum fine even when no ban is active.

The bigger risk is a fire that escapes your property. Under Washington law, anyone who negligently or willfully sets a fire, fails to prevent its spread, or fails to control it is liable for the full cost of suppression by the state, a municipality, or a fire district.¹⁰ Suppression costs for even a modest brush fire that requires a multi-engine response can reach tens of thousands of dollars. Local fire officials can also issue citations on the spot and order immediate extinguishment of any prohibited fire.
