Stormwater Permitting

The South Carolina Department of Health and Environmental Control is responsible for managing the states Stormwater Program. The program requires all construction sites of one acre or more, many industrial sites, and all regulated Municipal Separate Storm Sewer Systems (MS4s) to obtain stormwater permit coverage. Some sites will be able to obtain coverage under the state general permit, but sites that pose considerable risk to contaminate water may be required to obtain an individual permit.

SC DHEC’s Stormwater Permitting Section issues permit coverage for the above activites through the NPDES Permitting Program. Information on other permitting requests including extending or modifying existing approvals, all associated fees and Expedited Reviews can also be found via the links below.

The Importance of Stormwater Management 

Stormwater Management focuses on the control of stormwater runoff that is generated when precipitation from rain and snowmelt events flows over land or impervious surfaces and does not percolate into the ground. This is accomplished through the use of Best Management Practices (BMPs) and the proper implementation of a site specific Stormwater Pollution Prevention Plan.

Uncontrolled or untreated stormwater runoff may cause significant adverse impacts, to downstream structures and waterways by either increasing the quantity of water being released offsite, detrimentally impacting downstream water quality through the transportation of common pollutants found in stormwater runoff, or both.

Through the use of proper stormwater management, drainage systems can be designed to address water quantity and quality concerns, alleviating downstream flooding problems and aiding in the restoration of South Carolina’s waterways towards supportive conditions conducive to state wildlife and public usage.
