2016 Monitoring Plan Public Comment Period

The South Carolina Department of Health and Environmental Control's draft 2016 "Network Description and Ambient Air Network Monitoring Plan" (Plan) will be available for public comment from May 15, 2015 to June 14, 2015.  This Plan is an annual Environmental Protection Agency (US EPA) requirement and is submitted to the US EPA in July of each year. The Plan consists of a description of the South Carolina ambient air monitoring network and contains any changes to the network planned over the next 18 months. 

The Plan will be posted for 30 days on the Department's website starting on May 15, 2015. If you wish to make comments on this Plan, please email comments to:

Ambient Air Monitoring Network

DHEC operates air monitoring stations throughout South Carolina to measure the concentrations of pollutants in outdoor (ambient) air that are considered harmful to public health and the environment. The EPA sets national ambient air standards for each type of pollutant and sets minimum requirements for both the number and distribution of monitors among metropolitan statistical areas. The EPA also requires states to meet quality assurance and other standards.

DHEC monitors concentrations of six pollutants the EPA has designated as criteria pollutants:

  • Carbon monoxide (CO)
  • Nitrogen dioxide (NO2)
  • Ozone (O3)
  • Lead (Pb)
  • Inhalable particulate matter (PM 2.5 and PM10)
  • Sulfur dioxide (SO2)

We also monitor for fluoride, air toxics, pollution impacts (such as regional haze and acid rain) and other S.C.-specific pollution standards.

Visit DHEC's South Carolina Ambient Air Monitoring map to see the location of all the air quality monitoring stations in South Carolina. Click on a location to bring up a description of the monitoring site and an explanation of what we are measuring at that location. The map also provides historical graphs showing concentrations of major pollutants found at each monitoring station.

Ambient Air Network Monitoring Plan

The EPA requires states to have a yearly monitoring network plan in place and conduct periodic network assessments (every five years beginning in 2010).

Here is the most recent annual monitoring plan network plan and periodic network assessment.

1998-2011 Ambient Air Quality Monitoring Data Summaries

Monitoring the air we breathe is one of the most important responsibilities of the Bureau of Air Quality (BAQ). The data we collect is used by the U.S Environmental Protection Agency, individuals within DHEC, and the general public. A history of South Carolina's Ambient Air Quality Data Summaries and Criteria Pollutant Daily Maxima are presented below.

BAQ Annual Report (1990 - 2005) Ambient Air Quality Monitoring Data is located in the appendix, starting on page 45
