Wyoming's water quality standards are applicable to "waters
of the State". In some limited instances, the definition
adopted by Wyoming 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.
Wyoming water quality standards apply to all waters within the
State of Wyoming, with the exception of those waters that are
within Indian Country, as defined in 18 U.S.C. Section 1151. EPA's
approval of Wyoming'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.
