Did you know there are more than 2,300 regulated dams in South Carolina? DHEC oversees compliance for state-regulated dams through the Dams and Reservoirs Safety Program. The program is administered by DHEC’s Bureau of Water and was established in 1977 with the passage of the S.C. Dams and Reservoirs Safety Act.
The Dams and Reservoirs Safety Program State law and regulation require submission of plans and specifications and a written permit before a dam regulated under this program may be built, altered, or removed. DHEC reviews those plans and permits and also provides safety inspections, information and technical assistance to dam owners and operators across the state to help them stay in compliance with state laws and regulations.
Dams regulated under this law are classified based on both their hazard potential (high hazard, significant hazard, or low hazard) and their size (large, intermediate, small or very small).
Unless exempted by law, dams regulated by DHEC are classified based on size and hazards, and must meet one of the following criteria:
Hazard classification applies to potential loss of human life or property damage in the event of failure or improper operation of the dam or connected works.
Since 1977, numerous permits have been issued to construct, alter, repair, or remove dams in South Carolina. The program also conducts construction inspections and final inspections to ensure all work is performed according to the approved plans and specifications. Before a regulated dam or reservoir can be placed into operation, a written authorization to begin operations must be granted by the division.
The Environmental Quality Control Regional Offices are responsible for routine inspections and classification checks on dams. Routine inspections are performed on high hazard and significant hazard dams, and classification checks are done for low hazard dams by checking the area below the dams. Enforcement actions are used by the Bureau when necessary to ensure permits are obtained when required and to ensure compliance with permits.
Dam owners are responsible for maintaining the structural integrity of their dams. While DHEC does not provide engineering or maintenance services, the agency does provide technical assistance and information to help dam owners maintain compliance with safety regulations.
If you are a dam owner and are considering the alteration, repair or removal of a dam, please visit the dam permitting page.
If you are a resident who lives near or below a dam, please visit www.livingneardams.org.
