Storm Water RunoffStorm water runoff occurs when rain falls onto the ground and /or snow melts but is unable to infiltrate into the ground. It will then flow across the land, flowing to a nearby water body such as lakes and streams.

Urban RunoffUrban runoff is unable to infiltrate into the soil due to paved surfaces. Therefore, water flows into roadways, streets, sidewalks and eventually is collected through channels or storm drain inlets. These inlets are located in parks, rivers, and washes.

Runoff and Pollution

Pollution from runoff occurs when the water is running down the streets. It is constantly picking up pollutants such as animal feces, chemicals, oil, fertilizers, and pesticides as well as many other contaminants.

What Is The NPDES Stormwater Program?

The National Pollutant Discharge Elimination System (NPDES) Stormwater Program regulates stormwater discharges from three potential sources:•Municipal separate storm sewer systems (MS4)•Construction activities•Industrial activities

Operators of these sources may be required to receive an NPDES permit before they are able to discharge into local surface waters. Local surface waters are identified as streams, rivers, lakes or coastal waters.
