When fine particles of smoke are on the rise, and stagnant weather conditions prevail, Spokane Clean Air can restrict the use of burning devices and outdoor burning. This strategy is to keep fine particles from exceeding the federal, health-based air quality standards.
A color-coded system is used to report wood burning conditions:
Air pollution levels are low and dispersion is good. There are no restrictions on the proper use of the wood burning stoves, inserts and fireplaces.
This is a Stage 1 burn ban. Air pollution levels are rising or are already high due to poor dispersion. Use of wood burning devices is restricted. Only EPA-certified devices (wood, pellet stoves and inserts) may be used. The restriction is typically for the Smoke Control Zone, but can be extended countywide if conditions dictate. ALL outdoor burning is banned countywide under a Stage 1 and 2.
This is a Stage 2 burn ban. Air pollution has risen to a level threatening to public health, dispersion is poor and is not expected to improve in the next 24 hours. Use of all wood burning devices is prohibited. The ban is typically for the Smoke Control Zone, but can be extended countywide if conditions dictate. All outdoor burning is banned countywide under Stage 1 and 2, this includes chimneas, outdoor fireplaces, fire bowls, fire pits, wood chip electric smokers, wood/charcoal/pellet grills, and similar devices.
The boundaries of the Smoke Control Zone are roughly:
City of Spokane
North to Ownes Road
Spokane Valley to Idaho border
South to Gibbs Road
West to Hayford Road
