                      Subpart A--General Provisions
 
Sec. 131.4  State authority.

    (a) States (as defined in Sec. 131.3) are responsible for reviewing, 
establishing, and revising water quality standards. As recognized by 
section 510 of the Clean Water Act, States may develop water quality 
standards more stringent than required by this regulation. Consistent 
with section 101(g) and 518(a) of the Clean Water Act, water quality 
standards shall not be construed to supersede or abrogate rights to 
quantities of water.
    (b) States (as defined in Sec. 131.3) may issue certifications 
pursuant to the requirements of Clean Water Act section 401. Revisions 
adopted by States shall be applicable for use in issuing State 
certifications consistent with the provisions of Sec. 131.21(c).
    (c) Where EPA determines that a Tribe is eligible to the same extent 
as a State for purposes of water quality standards, the Tribe likewise 
is eligible to the same extent as a State for purposes of certifications 
conducted under Clean Water Act section 401.
