   4. Northern Sonoma Air Pollution Control District (Napa and environs): Formally allows EPA certified or District-approved masonry heaters, but the district has refused to approve any masonry heater.
   5. Missoula City/County Health Department in Montana: Allows only pellet stoves inside the city limits.  Outside the city limits, only one masonry heater model by the largest manufacturer Tulikivi has been approved, after petitioning based on the model's Washington testing.
