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 has implemented a Stormwater Management Program consistent with the Federal Clean Water Act and South Carolina Pollution Control Act.
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.
