Air Pollutants and Monitoring

Specific Air Pollutant Information

Each of these air pollutants have established methods to track their amounts present in the air we breathe (also called ambient air). Many of them involve specific regulations and laws to keep our health and environment safe.

In South Carolina, the U.S Environmental Protection Agency (EPA) establishes laws, standards, and regulations for states to follow. DHEC is responsible for maintaining the air quality in South Carolina.

Other Air Pollutants

There are many other compounds, chemicals, and elements in the air we breathe. The EPA maintains a list of hazardous air pollutants (HAP) and there are toxic air pollutants listed in Regulation 61-62.5 - Air Pollution Control Standard No. 8 - Toxic Air Pollutants. These are monitored through the processes that produce them, most often through the use of permits that are required by industrial sources that work with, store, or produce them but also through our Ambient Air Monitoring Network.

Those permits, and the regulations that support them, work together the make sure that the concentration of any HAP or Air Toxic released into the air is below any established limits that would cause harm to human health or the environment. Those regulations also can assess penalties to facilities that violate the conditions of their permits.
