Region 8 Tribal Program
EPA Region 8 is committed to helping tribes strengthen their abilities to manage environmental programs in Indian country, and to ensure that tribes have a voice in decisions that affect their land, air and water. The region serves 28 federally recognized tribes, located within the states of Colorado, Montana, North Dakota, South Dakota, Utah, and Wyoming.
The Regional Tribal Operations Committee (RTOC) provides an opportunity for discussion between tribes and EPA.
GAP is guided by the Guidance on the Award and Management of General Assistance Agreements for Tribes and Intertribal Consortia.
For more information regarding the administration of GAP in Region 8, see the Region 8 Tribal Contacts list.
Under the EPA Policy on Consultation and Coordination with Indian Tribes, EPA consults on a government‐to‐government basis with federally recognized tribes. For more specific guidelines on consultation with tribes in Region 8, contact Kimberly Varilek at 303-312-6264.
This guidance is intended to respond to and clarify questions that are most frequently raised by our internal and external customers and constituents, relating to: (1) Agency protocol in working with federally recognized tribes, (2) Agency support of federally recognized tribal governments in building capacity to manage environmental programs, and (3) Agency positions on environmental program responsibilities and jurisdiction.
