Auburn - Dewitt - C Avenue Air Monitoring Station, Auburn, California | Environmental Monitoring

Auburn - Dewitt - C Avenue is an air monitoring station located in Auburn, Placer County, California, United States. Operated by the Placer County Air Pollution Control District (APCD), this station is part of the broader US EPA Air Quality System (AQS) monitoring network, which tracks criteria pollutants and other atmospheric parameters to ensure compliance with National Ambient Air Quality Standards (NAAQS). The station serves the Auburn community and surrounding areas, providing data essential for public health advisories and regulatory assessments. As an air monitoring station, its primary function is to measure ambient air pollutants such as ozone, particulate matter (PM2.5 and PM10), carbon monoxide, sulfur dioxide, and nitrogen dioxide. The station's siting follows EPA guidelines to ensure representativeness of local air quality. While specific parameter coverage is not detailed, typical stations in California's network include continuous analyzers for gaseous pollutants and filter-based samplers for particulate matter. The station's operational status indicates ongoing data collection, contributing to the state's extensive air monitoring infrastructure. The environmental significance of this station lies in its role within California's air quality management framework. Placer County experiences air quality challenges from both urban and wildfire sources, making continuous monitoring critical for public health protection. Data from this station supports air quality index (AQI) reporting, attainment status determinations, and long-term trend analysis. By providing reliable measurements, the station helps inform emission reduction strategies and community awareness programs.

The Auburn area, located in the Sierra Nevada foothills, experiences air quality influenced by local urban emissions, agricultural activities, and seasonal wildfires. Monitoring stations like Auburn - Dewitt - C Avenue are essential for tracking criteria pollutants under the Clean Air Act. The station's location in a mixed residential-commercial area provides representative data for population exposure assessments. Parameter coverage typically includes ozone and particulate matter, which are of primary concern in California's Central Valley and foothill regions. Siting representativeness ensures that measurements reflect ambient conditions rather than local point sources, supporting accurate regulatory compliance evaluations.
