Waste generated at an industrial site, when exposed to rain or outdoor watering, can wash into rivers, streams and lakes. The NPDES program requires that the discharge of stormwater from certain types of industrial facilities to be reulated under a permit program.
Construction-related sediment erosion, paint, chemicals, debris and other pollutants discharge directly into storm drains during rainfall and wash into streams, rivers, and lakes.
The NPDES (National Pollution Discharge Elimination System) stormwater permit for construction activities is directed toward controlling the quality of stormwater runoff from construction activities.
