Inside the Missoula Air Stagnation Zone - Pellet Stoves
Since October 1, 1994, only approved pellet stoves may be installed inside the Missoula Air Stagnation Zone (Air Stagnation Zone as a .jpg). Approved pellet stoves have maximum emissions of 1 gram particulate per hour when tested by the approved testing method.
To install a pellet stove inside Missoula City limits, first obtain a permit at the Missoula City-County Health Department.
To install a pellet stove in the county outside city limits, obtain a mechanical permit from the County Building Department.
Missoula County Outside the Missoula Air Stagnation Zone
Since May 14, 2010, devices that can be installed in the county (Swan River Drainage of Northern Missoula County not affected by installation rules) and outside the Missoula Air Stagnation Zone are limited to:
* Wood stoves and pellet stoves with the EPA emissions certification label. Wood stove rules are changing at the nationallevel, so the EPA web page list of certified EPA solid fuel burning devices is currently not active.
* EPA Certified Cleaner Hydronic Heaters with average emissions of 7.5 grams per hour or less. Note that only Phase 2 Heaters with annual average emissions of 7.5 grams per hour or less from this list may be installed in Missoula County.
* Devices approved by the Missoula City-County Health Department with average emissions of 7.5 grams per hour or less.
* Devices approved by the Missoula City-County Health Department with a heat input capacity between 250,000 and 1,000,000 BTU/hr that have emissions at or less than 0.9 grams per 10,000 BTU/hr heat input.
Please install the cleanest burning device available that will provide the amount of heat you require. In the lists linked to above you will find several devices that qualify for installation in Missoula County.
To install a device in Missoula City first obtain a permit from the Missoula City-County Health Department, 301 W. Alder Street, top floor.
Outside Missoula City limits, a wood stove/boiler installation requires a mechanical permit from the County Building Department.
