The SWPPP is a document that outlines how a construction project will minimize stormwater pollution. Construction sites are a well-known source of sediment and other pollutants which can cause significant harm to rivers, lakes, coastal waters, and flood control facilities. The SWPPP describes the contractor’s activity to prevent pollution for the specific project. The SWPPP should be kept on the construction site and updated frequently to reflect changes at the site.

A SWPPP must be prepared and certified by a Qualified SWPPP Developer (QSD) and many other SWPPP tasks (i.e. inspections) must either be conducted directly by, or under the supervision of a QSD or QSP.
