The Woodstove change out project is a two year locally funded project that is allows the Butte-Silver Bow Health Department the ability to change out old, inefficient wood burning stoves and replace them with new EPA efficient wood burning stoves. Phase one of the project begun in the Greeley school area and will expand to surrounding areas in upcoming years. The main goal for the Woodstove Change Out Program is to lower small particulate matter known as PM 2.5. After several tests it has been determined that wood smoke from old non-efficient wood stoves is the leading cause of high levels of PM 2.5, which has contributed significantly poor air quality in Butte-Silver Bow County. Butte-Silver Bow is working with Silver Bow Hearth and Home to complete this initiative.
