Air Pollutants and Monitoring

The Clean Air Act is a federal law that defines responsibilities of the U.S Environmental Protection Agency (EPA) for protecting and improving the nation's air quality. There are also laws and regulations specifically established for South Carolina. DHEC is the designated authority for monitoring and maintaining South Carolina's ambient air. Both the Bureau of Air Quality and the Bureau of Environmental Services are involved in monitoring activites and the review of data.
