The term SWPPP Stands for Storm Water Pollution Prevention Plan.
As the term says, it is a plan to prevent pollution of storm water. They are required by the federal Clean Water Act and various State laws to try to reduce pollution via stormwater. They are broken up into 3 major industries: Construction, Industrial, and Municipal. They all require a plan for preventing and/or reducing storm water pollution from those industries. A SWPPP addresses all pollutants and their sources, including sources of sediment linked to construction, construction site erosion and all other activities associated with construction. These can include things such as regular inspections, reporting, storm water sampling, effluent limits, installation and maintenance of best management practices (BMP’s), etc. They may also require industry specific training/qualifications for personnel who are involved with the SWPPP design and implementation.
