Safe Open Burning

Ada County no longer issues burn permits or requires its Fire Districts to do so.  Ada County now allows open burning in rural areas, PROVIDED that the weather forecast permits and the Air Quality Index (AQI) is 60 or below.  Ada County cares deeply about our Treasure Valley air quality.  Help us keep our precious Treasure Valley air clean and safe by knowing and following these rules before you burn.
