Stormwater Permitting and Management

The U.S. Environmental Protection Agency has established regulations requiring states, counties and cities, including the City of North Charleston, to develop and implement a Stormwater Management Program to protect our waters from pollutants generated by stormwater runoff.  The City of North Charleston is implementing a Stormwater Management Program consistent with the Federal Clean Water Act and South Carolina Pollution Control Act, with the goal of reducing the amount of runoff pollution that eventually makes its way into local waters.

Stormwater Permitting

The City's NPDES Stormwater Discharge Permit requires the City to develop, implement, and enforce a program to reduce pollutants from stormwater runoff from construction activities that result in land disturbance.  Most land disturbing activities in the City require a Stormwater Permit.  The City has developed guidance in the form of a Stormwater Permitting and Design Manual.  The manual is available through the link provided below.
