The National Pollutant Discharge Elimination System (NPDEP)

All point source discharges require a permit under the Clean Water Act. In this way, the EPA is able to control and regulate the levels of water pollution in the united states.

A point source is “any discernible, confined, and discrete conveyance” of pollution into a body of water. This definition encompasses discharges from factories, sewage treatment plants, and any other direct introduction of pollutants into surface waters.

What do permits require?
  • A level of treatment or control that complies with the CWA’s discharge limitations.
  • Any other actions or prevention methods to protect surface waters.
  • Permitted Activities cease whenever necessary to comply with limits.
  • Maintenance and operation of pollution control systems by permit holder.
  • Permit holder must provide information to the EPA or state regulators.
  • Permit holder must grant inspectors entrance to grounds.
  • Set consequences for failure to comply.
  • A new permit must be obtained before current permit expires (every 5 years).

 

How are permits obtained?

Permits are obtained through the EPA or through state agencies (the EPA has determined how permits are granted on a state by state basis). The State of Minnesota deals with permit applications. Individual permits set specific levels of allowable pollutants and are granted on a case by case basis.

Applications and information on applying for point-source discharge are available through the EPA and the state of Minnesota.
