In 1991 South Carolina Legislation passed the Stormwater Management and Sediment Reduction Act (72-300) , which was crafted in close consultation with EPA regulators to ensure that the state's stormwater regulations contained standards that either met or surpassed the requirements mandated in Phase 1 of the NPDES Stormwater Program . This piece of legislation allowed South Carolina to obtain permitting authority over the NPDES Stormwater Program within the State's jurisdiction. Currently this responsibility resides with the Department of Health and Environmental Control (DHEC).
The Stormwater Management and Sediment Reduction Act's Standards were revised on June 28, 2002 to address phase II requirements mandated by the EPA. Under these revised standards any land disturbance activity greater than 1 acre or part of a Larger Common Plan will need to apply for NPDES coverage before that activity may begin.
DHEC grants NPDES coverage to the majority of land disturbance projects by issuing coverage approvals. These approvals grant NPDES coverage under one of the General Permits that are currently active. These General Permits are also issued and maintained by DHEC.
In some instances, it becomes necessary that an Individual Permit be issues for land disturbing activities that are deemed high hazards sites during the review process. These instances vary by a case-by-case review and will generally take more time to be granted NPDES coverage.
