In addition to sulfation plate monitoring stations in the later 1980' s, 

 the Air Quality Bureau operated from one to three continuous air-quality 

 monitoring stations from 1981-87. Parameters monitored included sulfur 

 dioxide, Beta scattering coefficient, total suspended particulate, sul- 

 fates, nitrates, wind direction, and wind speed. The continuous moni- 

 toring stations were gradually phased out after determining that United 

 States and Montana air quality standards were not being violated.
