Hazardous Air Pollutants

The N.C. Division of Air Quality (DAQ) operates the urban air toxics (UAT) monitoring network in conjunction with the national program, originally proposed and designed by the U.S. EPA in 1999. The UAT monitoring network was started as part of the EPA's effort to address toxic air pollutant emissions in urban areas.

Monitoring Sites

Currently, the UAT consists of seven sites, six urban and one rural.

UAT air monitoring is regularly conducted for volatile organic compounds (VOCs). Monitoring for selected aldehydes are conducted on a more limited basis at three sites.

The UAT monitoring network is a collaborative effort coordinated between state and local agencies:
