Where to Apply

In the coming months, six newly-permitted MS4 programs will begin implementation of the Construction Site Runoff Control and Post-Construction Stormwater Management Minimum Control Measures (MCMs) required in their permits. These MCMs require that each MS4 develop, implement, and enforce a program to reduce pollutants in stormwater runoff from land-disturbing activities. Each program must include provisions for the review of Stormwater Pollution Prevention Plans (SWPPPs) for construction activities occurring within their jurisdiction. On the dates noted below, SWPPPs and applications for construction activities must be submitted to the MS4s and receive approval from them prior to DHEC’s issuance of coverage under the NPDES Construction General Permit. For projects located in Beaufort County, requests for NPDES Construction permit coverage and Coastal Zone Consistency (CZC) Certification can be submitted to DHEC concurrently with application to the MS4 should this be necessary to expedite permitting times.  

A general flow chart for this process is available via the following link http://www.scdhec.gov/Environment/docs/NPDES-CZCTransMS4Areas.pdf.

The schedule for implementation for each of these MS4s is:
