Stage 1 burn bans in Chelan, Douglas and Okanogan counties expire at 4 p.m. on Wednesday, Dec. 18, according to the Washington Department of Ecology .
A Stage 1 ban prohibits use of uncertified wood-burning devices (including wood stoves, inserts and fireplaces) and all outdoor burning. Stage 2 bans prohibit all burning.
These activities may resume after the burn ban expires. However, Ecology urges people to think twice before burning because smoke from outdoor burning and wood-burning devices tends to build up at this time of year, when stagnant air traps smoke close to the ground.
