Tribes and Water Quality Standards
Water quality standards (WQS) provide the regulatory and scientific foundation for protecting water quality under the Clean Water Act (CWA). WQS not only set water quality goals for a tribe’s water bodies, but also serve as the regulatory basis for establishing water quality-based treatment controls and strategies. To administer a WQS program under the CWA, a tribe must apply to EPA for authorization to be treated in a similar manner as a state (TAS) (refer to the second tab above). To learn more about WQS and coverage in Indian country, please refer to the resources below.

Treatment in a Similar Manner as States (TAS)
Clean Water Act (CWA) Section 518(e) expressly provides for Indian tribes to play essentially the same role in Indian country that states do within state lands, authorizing EPA to treat eligible federally recognized Indian tribes in a similar manner as a state (TAS) for implementing and managing certain environmental programs.

- Water Quality Standards (CWA Section 303(c))
- Water Quality Certifications (CWA Section 401)
- National Pollutant Discharge Elimination System (NPDES) permitting (CWA Section 402)
- Dredge and Fill Permitting (CWA Section 404)
- Impaired Waters Listing (CWA Section 303(d))
- it is federally recognized;
- it has a governing body carrying out substantial governmental duties and powers;
- it has appropriate authority; and
- it is (or will be) capable of carrying out the functions of the particular program.
In May 2016, EPA published a final rule revising the interpretation of the Congressional delegation of authority under CWA Section 518, streamlining the process for applying for TAS for CWA regulatory programs, including the water quality standards program.
To assist in the TAS application process to administer the 303(c) and 401 programs, EPA has provided the following streamlined TAS Application Template and other documents:- TAS Application Template for Water Quality Standards and Water Quality Certifications
- Overview of TAS for the Water Quality Standards program (pdf)
- Frequently Asked Questions about TAS for the Water Quality Standards program (pdf)
- Procedural steps for Water Quality Standards TAS applications (pdf)
