Pretreatment Permits

The Industrial Pretreatment Program prevents the discharge of pollutants to Publicly-Owned Treatment Works (POTWs) which will interfere with the operations of the POTW or its use and disposal of municipal biosolids. In addition, the Pretreatment Program prevents the introduction of pollutants to POTWs that may pass through into rivers, lakes, and streams causing toxicity or other impacts. Implementation of the Pretreatment Program is defined at 40 CFR Part 403. These regulations describe the responsibility of the EPA, states, POTWs, and industrial users in protecting the POTWs, sewer systems, biosolids, receiving waters, and worker health and safety. You may visit the EPA National Pretreatment Program website for more information on waste water treatment involving Biosolids/Sludge.

For more information please contact the NDPDES Program.

Dental Amalgam Rule

As you may know, the United States Environmental Protection Agency (EPA) published a new rule, the Dental Amalgam Standard (40 CFR 441), on June 14, 2017. This rule (effective July 14, 2017) requires dental offices that place and/or remove amalgam to install and maintain amalgam separators or equivalent devices, implement specified Best Management Practice (BMPs), and keep records. All dental offices, except mobile units and those practicing a few exempted specialties, are required to submit a One-Time Compliance Report (OTC). The North Dakota Department of Environmental Quality (department) will implement the Dental Amalgam Standard for all dental offices that discharge to a Publicly Owned Treatment Works (POTW) located outside Bismarck, Mandan, Fargo, West Fargo, and Grand Forks.

  • For dental offices that do not place and/or remove amalgam,
  • i. The OTC report must be submitted by December 31, 2019 to: North Dakota Department of Environmental Quality 4201 Normandy Street – Division of Water Quality Bismarck, ND 58503-1324

  • For dental offices that do place and/or remove amalgam,
  •  i. One amalgam separator or equivalent device must be installed and operational and;
  • ii. Specified BMPs must be in place and;
  • iii. Record keeping requirements must be implemented by July 14, 2020.

  • Please Note: The department has made deadlines for submitting reports earlier than the rule requires to allow sufficient time to review all information and confirm compliance by October 12, 2020. Dental offices that have opened or have transferred ownership after July 14, 2017 are required to be in compliance when first discharging and submit the OTC report within 90 days of discharging dental amalgam process wastewater to the city sewer system.
