Through cooperative agreements with the U.S. Department of Energy, NCSL provides staff support to numerous state and tribal working groups. These working groups serve as a platform for tribal leaders and/or their designated representatives and federal officials to openly discuss topics such as energy development, environmental cleanup of DOE facilities and nuclear energy activities in fulfillment of DOE’s federal trust responsibility. Regular working group meetings provide a forum for information exchange, mutual learning, and relationship building among states, tribes and the DOE.
