South Dakota's water quality standards are applicable to "waters
of the State". In some limited instances, the definition
adopted by South 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.
EPA has included the State's water quality standards in their
entirety here for context and as supplementary information for
the reader.
South Dakota water quality standards apply to all waters within
the State of South 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 South 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.
