§130.7. Total maximum daily loads (TMDL) and individual water quality-based effluent limitations. — Inbound Citations

(B) Effluent limits developed to protect a narrative water quality criterion, a numeric water quality criterion, or both, are consistent with the assumptions and requirements of any available wasteload allocation for the discharge prepared by the State and approved by EPA pursuant to 40 CFR 130.7.

(1) TMDLs in accordance with sections 303(d) and (e)(3)(C) of the Act and § 130.7 of this part.

The following definitions apply in this part. Terms not defined in this section have the meaning given by the Clean Water Act and EPA implementing regulations.

(3) The process for developing total maximum daily loads (TMDLs) and individual water quality based effluent limitations for pollutants in accordance with section 303(d) of the Act and § 130.7(a) of this regulation.

(2) Identification of water quality-limited waters still requiring TMDLs (section 303(d)), pollutants, and the priority ranking including waters targeted for TMDL development within the next two years as required under § 130.7(b) in accordance with the schedule set for in § 130.7(d)(1).

(3) For the purposes of listing waters under § 130.7(b), the term “water quality standard applicable to such waters” and “applicable water quality standards” refer to those water quality standards established under section 303 of the Act, including numeric criteria, narrative criteria, waterbody uses, and antidegradation requirements.

(4) The list required under §§ 130.7(b)(1) and 130.7(b)(2) of this section shall include a priority ranking for all listed water quality-limited segments still requiring TMDLs, taking into account the severity of the pollution and the uses to be made of such waters and shall identify the pollutants causing or expected to cause violations of the applicable water quality standards. The priority ranking shall specifically include the identification of waters targeted for TMDL development in the next two years.

(4) The list required under §§ 130.7(b)(1) and 130.7(b)(2) of this section shall include a priority ranking for all listed water quality-limited segments still requiring TMDLs, taking into account the severity of the pollution and the uses to be made of such waters and shall identify the pollutants causing or expected to cause violations of the applicable water quality standards. The priority ranking shall specifically include the identification of waters targeted for TMDL development in the next two years.

(ii) A description of the data and information used to identify waters, including a description of the data and information used by the State as required by § 130.7(b)(5); and

(2) Identification of water quality-limited waters still requiring TMDLs (section 303(d)), pollutants, and the priority ranking including waters targeted for TMDL development within the next two years as required under § 130.7(b) in accordance with the schedule set for in § 130.7(d)(1).

(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.
