The Environmental Protection Agency (EPA) is responsible for setting National Ambient Air Quality Standards (NAAQS) for pollutants considered harmful to public health and the environment. Currently there are six principal NAAQS pollutants; they are often called criteria pollutants.
Of those six, ground-level ozone and particle pollution pose the most widespread health threats. However, they all have the potential to cause damage to human health and the environment. DHEC's Bureau of Air Quality maintains a monitoring network for all criteria pollutants and provides the monitoring information to the public and the EPHT program.
DHEC Air Pollution Reduction Strategies
B2 at school
B2 (Breathe Better) is an anti-idling/clean air campaign designed to help protect the health and safety of children by reducing harmful vehicle emissions around school campuses. Students, faculty, staff, and community partners work together to provide solutions.
Spare the Air Awards
These awards recognize environmental leaders (i.e., companies, community partners, and individuals) committed to promoting and practicing air quality strategies and environmental practices to improve air quality in South Carolina.
Vehicles contribute substantially to air pollution and can have negative impacts on human health and the environment. This effort teaches you how you can help reduce vehicle miles traveled (VMT) and mobile source emissions to improve air quality.
