Solid fuel burning devices such as woodstoves and fireplaces are the primary source of winter air pollution throughout Missoula County. In order to clean up the air and protect residents' health, the Missoula City-County Health Department has implemented rules about which devices may be installed and when they must be removed.

Background

Throughout Missoula County and Western Montana, the National 24-Hour Particulate Matter for particulate 2.5 microns in diameter and smaller (PM2.5) is threatened in the winter when temperature inversions trap air pollution to the valley floors. The main source of winter air pollution comes from residential woodstoves and fireplaces. To protect public health and keep particulate levels below the PM2.5 standard, it is crucial that wood stoves burn cleanly and that only the cleanest burning devices are installed. Over the years, several residential woodstove (solid fuel burning device) rules have been implemented in the Missoula Air Stagnation Zone . Efforts by many individuals over the decades has greatly reduced wood smoke levels and improved Missoula's air quality. Because smoke from woodstoves causes elevated particulate levels through out the county, new woodstove installation rules went into affect in 2010. Only clean burning devices will be permitted for installation through most of Missoula County.
