MT BELL BLDG Air Monitoring Station, Rifle, Colorado | Environmental Monitoring

MT BELL BLDG is an air monitoring station located at 200 W. 3rd St. in Rifle, Garfield County, Colorado, United States. It is part of the state's ambient air quality monitoring network managed by the Colorado Department of Public Health and Environment. The station supports the US EPA Air Quality System (AQS) by collecting data on criteria pollutants and other parameters to assess regional air quality. As a fixed-site monitoring station, MT BELL BLDG operates under the regulatory framework of the Clean Air Act and EPA monitoring requirements. The station likely measures pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, depending on its siting objectives. Monitoring stations in Colorado are strategically placed to characterize urban, suburban, and background air quality, with a focus on areas impacted by oil and gas development, transportation, and industrial sources. The data from MT BELL BLDG supports public health protection by informing air quality index (AQI) reports and regulatory compliance assessments. The station's location in Rifle, a town in the Colorado River valley, provides valuable data on air quality in a region with energy extraction activities. Continuous operation ensures long-term trend analysis and helps evaluate the effectiveness of emission reduction strategies.

The MT BELL BLDG monitoring station is situated in Rifle, Colorado, a community in the Colorado River valley surrounded by the Rocky Mountains. The region experiences a semi-arid climate with temperature inversions that can trap pollutants near the surface. Local air quality is influenced by oil and gas development, vehicle emissions, and occasional wildfires. The station's siting is representative of a small urban area with industrial activity, making it important for assessing exposure risks and compliance with National Ambient Air Quality Standards (NAAQS).
