(i) Include information on the substance and basis of the tribe's assertion of authority to regulate the quality of reservation waters;

(ii) Be provided to all appropriate governmental entities; and

(iii) Provide 30 days for comments to be submitted on the tribal application. Comments shall be limited to the tribe's assertion of authority.

(3) If a tribe's asserted authority is subject to a competing or conflicting claim, the Regional Administrator, after due consideration, and in consideration of other comments received, shall determine whether the tribe has adequately demonstrated that it meets the requirements of §130.16(a)(3).

(4) Where, after the effective date of this rule, EPA has determined that a tribe qualifies for TAS for the CWA Section 303(c) Water Quality Standards Program, CWA Section 402 National Pollutant Discharge Elimination System Program, or CWA Section 404 Dredge and Fill Permit Program, and provided notice and an opportunity to comment on the tribe's assertion of authority to appropriate governmental entities as part of its review of the tribe's prior application, no further notice to governmental entities, as described in paragraph (c)(2) of this section, shall be provided with regard to the same tribe's application for the CWA Section 303(d) Impaired Water Listing and TMDL Program, unless the application presents to the EPA Regional Administrator different jurisdictional issues or significant new factual or legal information relevant to jurisdiction.

(5) Where the Regional Administrator determines that a tribe meets the requirements of this section, he or she shall promptly provide written notification to the tribe that the tribe is authorized to administer the CWA Section 303(d) Impaired Water Listing and TMDL Program. Such tribe shall be considered a “State” for purposes of CWA section 303(d) and its implementing regulations. With respect to the timing requirement for submittal of an authorized tribe's first list of impaired waters pursuant to §130.7(d)(1), the tribe's first list is due on the next listing cycle due date that is at least 24 months from the later of either:

(i) The date EPA approves the tribe's TAS application pursuant to this section; or

(ii) The date EPA-approved or EPA-promulgated water quality standards become effective for the tribe's reservation waters.
