A Stormwater Pollution Prevention Plan (SWPPP) is a sediment and erosion control plan that describes all of the construction site operator’s activities to prevent stormwater contamination, control sedimentation and erosion, and compley with the requirement of the Clean Water Act.
A SWPPP may also be called a “construction best practices plan”, “sediment and stormwater plan”, or a “stormwater management plan”. In any case, these documents all have the same objective, which is to identify, prevent and/or control stormwater pollution. These documents must be submitted with submitted with each Notice of Intent requesting coverage under the 2006 GCP. In reference to R.72-300, the term SWPPP is synonymous with the term Stormwater Management and Sediment Control Plan.
It is very important that each SWPPP is developed to address the specific site conditions, is fully implemented, and is kept up-to-date to reflect changes at your site. Failure to meet these conditions may result in significant fines from the EPA or SC DHEC.
Best Management Practices (BMPs) are an essential part to any stormwater management plan.
In order to terminate NPDES coverage the site must achieve 70% permanent vegetative cover.
Site Inspections are required to be conducted by a certified inspector until NPDES coverage is terminated.
SC DHEC requires that the following should be included in a site-specific SWPPP when applying for coverage under the 2006 NPDES Costruction General Permit:
- Project Narrative
- Drainage Maps
- Drainage Reports
- BMP Maintenance Instructions
- On-site SWPPP Attachment (Recommended)
For an in-depth checklist on what to include in a SWPPP submitted to SC DHEC, please see the Plan Review Checklist for Design Professionals.
