- Standards of Water Quality for the State of North Dakota (PDF) (51 pp, 326K)
- (Effective September 16, 2010)
North Dakota's water quality standards are applicable to "waters of the State". In some limited instances, the definition adopted by North Dakota for "waters of the State" as part of its water quality standards may result in water quality standards that are more comprehensive than required under section 303(c) of the Clean Water Act and the implementing federal regulations. Specifically, North Dakota has adopted additional provisions related to groundwater that are outside the scope of the Clean Water Act and implementing federal regulations. EPA has included the State's water quality standards in their entirety here for context and as supplementary information for the reader.
North Dakota water quality standards apply to all waters within the State of North Dakota, with the exception of those waters that are within Indian Country, as defined in 18 U.S.C. Section 1151. EPA's approval of North Dakota's water quality standards was not intended as an action to approve or disapprove water quality standards applying to waters within Indian Country. EPA, or eligible Indian Tribes, as appropriate, will retain responsibilities for water quality standards within Indian Country.
