The Yakima Regional Clean Air Authority has declared a stage one burn ban in the Lower Valley, this just on the heels of declaring a stage two burn ban in the Upper Valley.
According to the clean air authority, Friday night's winds were sufficient to clear out stagnant air, with the city of Yakima demonstrating the worst air quality.
Air quality conditions are poor throughout Yakima County and the clean air authority is asking residents who can legally burn to voluntarily withhold from doing so in the interest of public health. Air conditions are expected to worsen Wednesday and Thursday.
No agricultural burning is allowed.
A stage one burn ban means the use of any fireplace, uncertified wood stove or uncertified fireplace insert is prohibited unless it's a home's only adequate means of heating.
The use of certified wood stoves, certified fireplace inserts and pellet stove inserts are allowed in the Lower Valley.
No excessive smoke is allowed from wood burning beyond a 20 minute startup.
