TDAT was designed to help users quickly identify tribes and provide appropriate tribal contact information to assist with initiating Section 106 consultation. Two key aspects of TDAT are its ability to:

  1. Link tribes' areas of interest down to the county level, and
  2. Perform a variety of queries related to tribes.

TDAT v2.1 was developed by the Office of Environment and Energy's Environmental Planning Division (EPD) to assist users with Section 106 compliance and tribal consultation.

State reports link tribes to their counties of interest in the particular state. Tribes may reside in or outside of that state. Check back frequently for updates.
