RED BLUFF-310 S. MAIN STREET is an air monitoring station located at 310 S. Main Street in Red Bluff, California, within Tehama County. The station is part of the California Air Resources Board's monitoring network and contributes to the US EPA's Air Quality System (AQS), which tracks criteria pollutants and other atmospheric parameters across the United States. As an air monitoring station, it typically measures pollutants such as ozone, particulate matter (PM2.5 and PM10), carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead, in accordance with the National Ambient Air Quality Standards (NAAQS). The station's siting follows EPA guidelines to ensure representativeness of local air quality, often placed in urban or suburban settings to capture population exposure. The station plays a key role in regional air quality management, supporting regulatory compliance and public health advisories. Data from this station helps inform local and state air quality indices, and contributes to long-term trend analysis for the Sacramento Valley air basin.

Red Bluff is located in the Sacramento Valley, an area prone to temperature inversions that can trap pollutants, especially during winter months. The region experiences elevated particulate matter from agricultural activities, wildfires, and vehicle emissions. The station's location on Main Street provides representative sampling of urban roadside exposure, which is critical for assessing compliance with NAAQS and protecting public health.
