Old High School is an air monitoring station located at 1501 Acquoni Rd. in Swain County, North Carolina, United States. Operated by the Eastern Band of Cherokee Indians of North Carolina, the station is part of the broader US EPA Air Quality System (AQS) network, which monitors criteria pollutants and other parameters to ensure compliance with National Ambient Air Quality Standards (NAAQS). The station's last reported sample date is September 30, 2025, indicating ongoing operations. As a tribal-operated monitoring site, Old High School operates under the regulatory framework of the Clean Air Act, which mandates ambient air quality monitoring across the country. The station likely measures key pollutants such as ozone, particulate matter, and nitrogen dioxide, though specific parameters are not detailed. The site's location in a rural area of the Great Smoky Mountains region provides representative data for background air quality, complementing urban monitoring stations. The environmental significance of this station lies in its role in tracking air quality in a region known for its natural landscapes and tourism. Data from Old High School helps assess the impact of local emissions and long-range transport on air quality, supporting public health advisories and regulatory decisions. The station's operation by a tribal agency underscores the collaborative efforts in environmental monitoring across diverse jurisdictions.
Environmental context
The station is situated in the mountainous region of western North Carolina, an area characterized by forested terrain and proximity to the Great Smoky Mountains National Park. Air quality here can be influenced by both local sources (e.g., residential heating, traffic) and regional transport of pollutants from urban and industrial areas. Monitoring at this site provides critical data on background ozone and particulate levels, which are essential for understanding regional air quality trends and protecting sensitive ecosystems.
