National Pollutant Discharge Elimination System – NPDES Program

Who needs to apply?


All persons discharging or proposing to discharge pollutants from a point source into any waters of the state are required to apply for and have a permit under the National Pollutant Discharge Elimination System (NPDES) to discharge including all significant industrial users discharging to a publicly owned treatment works.

The Nebraska NPDES program encompasses a number of different types of discharges including:

  • municipal
  • commercial
  • industrial wastewater
  • industrial discharges to public wastewater treatment systems (also known as the Nebraska pretreatment program)
  • industrial and municipal storm water
  • municipal combined sanitary and storm sewer overflows and discharges
  • livestock waste control

The Department is responsible for developing and issuing NPDES permits, and for insuring that permitted facilities comply with permit requirements.
State regulations pertaining to these programs are:
Discharge Monitoring Reports (DMRs) and NetDMR

The Electronic Reporting Rule requires regulated entities to report DMRs electronically, instead of filing written paper reports. The Department has chosen to use NetDMR to accept electronic DMR submissions.

NetDMR guidance and information can be found here: NetDMR



When Do I Apply?

Regulations require a site-specific NPDES permit application be submitted to NDEE at least 180 days prior to the date of first discharge. It is important that you submit a complete and accurate permit application. The 180-day period does not start until a complete application is received. If changes are made or additional information is submitted or is required, the 180-day period may start over. NPDES permits are public noticed for 30 days before being issued. If comments are received and a hearing is required, the Department would schedule a hearing and respond to any comments received at the hearing. This may require an additional 60 to 90 days.

General Permit authorizations may take from 7 to 30 days as indicated below.
