The Guidance on Awards of Grants to Indian Tribes under Section 106 of the Clean Water Act (the Guidance) is intended to help tribal water quality program managers, staff, and other tribal environmental decision makers design and implement effective and successful water quality programs. It also establishes procedures and guidelines for EPA regions to consider when awarding and administering grants to federally recognized Tribes.

Reporting requirements and data management expectations for all Tribal programs are a key component of the Guidance. Tribes are developing tribal assessment reports that contain information about water quality on tribal land and demonstrate national results for the Section 106 Tribal program. A tribal assessment report consists of the following. For each step, regional supplemental information is provided farther down this page:

  1. a description of the monitoring strategy;
    Regional supplement
  2. a water quality assessment; and
    Regional supplement
  3. surface water quality monitoring data submitted electronically in a STORET-compatible format.
    Regional supplement

You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more about PDF, and for a link to the free Adobe Reader.

The Guidance and its (non-regional) supplements are available on EPA's Clean Water Financing website, and the STORET-compatible Data Template (also referred to as the WQX Web Template) is available along with other resources at the WQX Web Resources and Download website.

The documents below have been developed to assist Tribes in completing reporting requirements. These regional supplements support and further clarify the reporting requirements outlined in the Tribal 106 Guidance, and serve as additional tools for EPA and tribal staff to use as they implement the Guidance.
