Municipal/Industrial Discharge Permits
North Dakota's NDPDES program is responsible for regulating discharges of pollutants from point sources
into waters of the state. Any discharge of wastwater from a point source must have a NDPDES permit prior
to discharging to be in compliance with state and federal regulations.
For a new point source, a completed NDPDES application must be submitted for review.
Review of the application, developing the permit, providing for public comment and finalizing the permit may
take up to 180 days. Each permit takes into account site specific information to limit discharges so that
the state's water quality standards are met.
The Department does not issue individual permit limits prior to completing the permit
review process. However, facilities treating domestic wastewater may expect to meet limits similar
to those in the general permits for discharges from waste stabilization ponds and domestic
wastewater treatment facilities (NDG12-, 22-, 32- and 420000).
If a facility meets the requirements for coverage under a general permit, they may request coverage under
that permit, a process which may take 30 to 60 days.
*Domestic wastewater treatment systems must also be reviewed and approved by the
Division of Municipal Facilities.
