Municipal Separate Storm Sewer Systems

Stormwater runoff from urban and industrial areas can contain harmful pollutants. To help keep these pollutants from being washed or dumped into surface waters, operators of municipal separate storm sewer systems (known as MS4s) must get a permit and develop a stormwater management program.

Individual NPDES Permits

An individual NPDES permit is tailored to a specific discharge and location. These are typically outfalls from municipal sewage treatment facilities or industrial plants that discharge to surface waters of Delaware. The NPDES permit specifies limitations, monitoring requirements, and other terms and conditions that the permittee must meet in order to be allowed to discharge.


National Pollutant Discharge Elimination System

The National Pollutant Discharge Elimination System (NPDES) regulates point sources that discharge pollutants into the state’s surface water bodies. It helps ensure that the state’s water bodies can meet their designated uses, such as providing drinking water, being safe for swimming or fishing, or supporting aquatic life.
