A Stormwater Pollution Prevention Plan is a site-specific document that identifies how a construction project will prevent sediment and pollutants from leaving the site and entering nearby waterways. In New York State, most construction activities that disturb one acre or more of land require coverage under the NYSDEC SPDES General Permit for Stormwater Discharges from Construction Activity, and a SWPPP is a core requirement of that coverage. The plan describes erosion and sediment control practices, stormwater management measures, inspection procedures, and the responsibilities of the parties involved.
