Sec.  124.51  Purpose and scope.


    (a) This subpart sets forth additional requirements and procedures 
for decisionmaking for the NPDES program.
    (b) Decisions on NPDES variance requests ordinarily will be made 
during the permit issuance process. Variances and other changes in 
permit conditions ordinarily will be decided through the same notice-
and-comment and hearing procedures as the basic permit.
    (c) As stated in 40 CFR 131.4, an Indian Tribe that meets the 
statutory criteria which authorize EPA to treat the Tribe in a manner 
similar to that in which it treats a State for purposes of the Water 
Quality Standards program is likewise qualified for such treatment for 
purposes of State certification of water quality standards pursuant to 
section 401(a)(1) of the Act and subpart D of this part.
