SUPPLEMENTARY INFORMATION: This notice contains a compiled list of
State and Tribal water quality standards review/revisions which were
approved by EPA for the period beginning on October 1, 1991 and ending
on August 31, 1995. The most recent list of review and revisions of
State water quality standards was published on November 24, 1993 (58 FR
62124). Today's notice identifies both State and Tribal regulatory
documentation that contains the State and Tribal water quality
standards as well as dates of State/Tribal adoption and EPA approval.
Additionally, a listing of Tribes that have obtained EPA approval to
administer the water quality standards program is included in this
notice. The following information is not included in this notice: (1)
The text of the water quality standards, (2) any conditions (including
disapprovals of portions of the State/Tribal submittals) that might
have been attached to the approvals, or (3) Tribal application
materials submitted to EPA for authorization to administer the water
quality standards program.
The text of a State's or Tribe's standards and copies of the
approval letters can be obtained from the State's or Tribe's pollution
control agency or the appropriate EPA Regional Office (see above).
Proprietary publications such as those of the Bureau of National
Affairs also contain the text of State/Tribal water quality standards.
