Air Quality Monitoring

The purpose of the Butte-Silver Bow Air Quality Program is to monitor, assess and provide information on countywide ambient air quality conditions and trends as specified by the Montana and Federal Clean Air Acts.  The current Air Quality Status is displayed on the sign in front of the Butte-Silver Bow Health Department located at 25 West Front Street.

Air Monitoring Station

This historical site is at a closed elementary school in a residential neighborhood on the north side of Butte and very near an operating open pit copper mine. Particulate Matter (PM) 10 and PM2.5 data collected at this site represents population exposure on a neighborhood scale. Continuous PM10 data is used to monitor NAAQS compliance in the local non-attainment area. Continuous PM2.5 data is reported to the Today's Air website and is used for public health protection plans during periods of poor air quality.
