What’s a TMDL?

A TMDL, Total Maximum Daily Load, is a calculation of the maximum amount of a pollutant from point sources, directly from outfall pipes or from a specific definable source, and non-point sources, pollution from many scattered sources, that a waterbody can receive and still meet water quality standards. A TMDL must include a margin of safety and consideration of seasonal variations within the waterbody. Under Section 303 of the Clean Water Act the Total Maximum Daily Load was established as a means of reducing water pollution. For more information, please visit the Department of Health and Environmental Control's TMDL website or the Environmental Protection Agency TMDL Website.

Who establishes TMDLs in South Carolina?

Water quality standards for South Carolina are declared by the Department of Health and Environmental Control with approval by the South Carolina General Assembly.
