Stormwater Pollution Prevention Plan (SWP3)

The CGP requires construction site operators to develop and implement a Stormwater Pollution Prevention Plan (SWP3) prior to commencing construction.

A SWP3 is a document that outlines construction plans and best management practices (BMPs) to control pollutants that may be discharged in stormwater runoff. Small Business and Local Government Assistance (SBLGA) has developed templates to help you develop your SWP3.
