Stormwater Management Program

Mission Statement:

The mission of the Department is to develop and implement a SWMP to comply with the regulatory requirements of the Permit as well as to protect, maintain, and enhance water quality and the environment of Berkeley County and the short-term and long-term public health, safety, and general welfare of the citizens of Berkeley County.

Program History:

On January 30, 2006, the South Carolina Department of Health And Environmental Control (SCDHEC) issued the National Pollutant Discharge Elimination System (NPDES) General Permit for Storm Water Discharges from Regulated Small Municipal Separate Storm Sewer Systems (MS4s). Berkeley County is a Regulated MS4 operator and must comply with the NPDES General Permit (Permit) requirements. The Permit requires the County to develop, implement and enforce a Stormwater Management Program (SWMP) to reduce the discharge of pollutants from our MS4 to the maximum extent practicable (MEP), to protect water quality, and to satisfy the appropriate water quality requirements of the Clean Water Act.

On July 1, 2008, the County was granted permission to discharge storm water to receiving waters in the State of South Carolina from its regulated area subject to the Permit requirements.

The current Permit issued by SCDHEC became effective on January 1, 2014. This current Permit replaces the 2006 Permit.

In October 2015, the County entered into Intergovernmental Agreements (IGAs) with the Cities of Goose Creek and Hanahan, obligating the County to manage the municipal MS4 permits. More information about these IGAs is available under the Stormwater Links.

The Stormwater Utility Ordinance was adopted in 2014, and amended in 2018 to establish the permanent fee rate structure. Information on the fee is available on the Stormwater Utility Fee page.
