This page contains resources from NTAA and EPA to help Tribes understand and apply for Treatment as a State (TAS) status under the Tribal Authority Rule (TAR) of the Clean Air Act (CAA). TAS provides that Tribes will be treated in the same manner as states for virtually all CAA programs. The TAR provides for a grants to Tribes when they secure TAS with approved CAA programs. Tribes with TAS can secure authority over all air resources within the exterior boundaries of a reservation (including non-Indian owned fee lands). For non-reservation areas, Tribes must demonstrate the basis for jurisdiction.
NTAA encourages Tribes to secure TAS to express their sovereignty and TAS can help secure funding for air quality programs. The resources below will help Tribes learn more about TAS and learn the steps on how to apply.
