Stormwater Pollution Prevention Plan (SWPPP) is a site-specific plan to reduce or eliminate stormwater pollution during the building of a new facility or site. A grading plan is more stringent than an erosion control plan when it comes to projects with one or more grading. An NPDES permit and the Clean Water Act, the EPA regulations, and the EPA’s Construction General Permit outlined in this paper are legally enforceable obligations for construction or project managers to follow. The civil engineer typically implements temporary or permanent environmental best management practices (BMPs) as part of this plan. Protecting wetlands and aquatic ecosystems, flood control, public health protection, and water conservation are just some of the SWPPP’s many advantages.
