Do I need a SWPPP for my project?

If your project will disturb one acre or more of land, you need NPDES Construction General Permit coverage, which requires a SWPPP. You also need one if your site is part of a larger common plan of development.

How often do I need site inspections?

Inspections are required at minimum once every seven calendar days across all active construction areas until final stabilization (70% permanent vegetative cover) is achieved.

Can I do the inspections myself?

For sites over 2 acres, inspections must be performed by a CEPSCI-certified inspector. For sites of 2 acres or less not part of a larger plan, the permittee may perform inspections if trained.

What is CEPSCI certification?

CEPSCI stands for Certified Erosion Prevention and Sediment Control Inspector, a certification program administered by Clemson University that qualifies individuals to perform SWPPP inspections.

When can I terminate my NPDES permit?

You can submit a Notice of Termination when final stabilization is achieved on all disturbed areas, all temporary erosion control measures have been removed, and permanent stormwater controls are functioning.

Can I get fined for SWPPP violations?

Yes. SCDES can issue enforcement actions including fines reaching thousands of dollars per day per violation under both state and federal law. Stop-work orders can halt your project entirely.
