The Western North Carolina Regional Air Quality Agency monitors and regulates Buncombe County's air quality to safeguard public health and the environment, while preserving the quality of life and economic vitality of the area.

The Western North Carolina Regional Air Quality Agency (WNCRAQA) is one of three local programs in North Carolina. The Agency enforces Air Quality regulations in Buncombe County and the City of Asheville. Regulations cover everything from open burning to asbestos demolition, as well as industrial facilities. WNCRAQA also has an air monitoring program that measures ozone and particulate matter in the county. The Agency is overseen by an independent board of five members, of which three are appointed by the Buncombe County Commission, and two by the Asheville City Council.
