The National Air Toxics Information Clearinghouse (NATIC) is a program administered by the Environmental Protection Agency (EPA). This information network was developed by the EPA to provide state and federal air pollution control experts with air pollution data. The computerized data base is headquartered in North Carolina, but air pollution control officers nationwide are able to access the data.

NATIC is a "one-stop shop" for emissions data for state enforcement officers, according to the EPA. Included on the network is information on air toxics programs, ambient air quality standards, pollution research, non-health related impact of air pollution, permits, emissions inventories, and ambient air quality monitoring programs.
