Stormwater Pollution Prevention Plans

07/17/25

“How can we make plans to prevent new construction from polluting stormwater runoff?”

Construction activities such as soil tillage, hazardous material storage, and waste disposal can create pollutants that are carried into water bodies by stormwater. This can turn into a major environmental and public health problem if no regulations exist. Thankfully, in the U.S, new construction projects are required to submit a Stormwater Pollution Prevention Plan by the National Pollutant Discharge Elimination System (NPDES) permit program established under the Clean Water Act. Stormwater pollution prevention plans must include a site map, construction sequencing of the expected activities, potential pollution sources, best management practices undertaken to prevent pollution discharge, and supporting hydrological calculations.
