A Stage 1 burn ban that will continue until at least Friday (Dec. 13) was imposed in Okanogan, Chelan and Douglas counties as of 4 p.m. Monday (Dec. 9) by the Washington Department of Ecology.

Poor dispersion is expected to degrade air quality over the next few days, Ecology said in a press release.

The ban will continue until at least 10 a.m. Friday and then may be lifted, depending on air quality conditions, or extended.

The ban applies to all outdoor burning, including residential, agricultural and forest burning. The use of uncertified wood-burning devices — including fireplaces, wood stoves and inserts — is prohibited unless they are a home’s only adequate source of heat.

Certified wood-burning devices and pellet stoves are allowed.
