The Exchange Network

The EN is a partnership among States, Territories, Tribes, and the U.S. EPA that is improving and expanding the exchange of environmental information. The TGG provides input to the EN on matters pertaining to tribal participation in the Exchange Network.

The Exchange Network Tribal Governance Group (TGG) is comprised of tribal professionals working on various aspects of the EN whose primary purpose is to ensure representation of tribal perspectives and issues in the overall Exchange Network governance structure, and to foster and enhance tribal participation in the Network. Current TGG members have over 40 years cumulative experience on Exchange Network topics and many of them have been directly involved in implementing EN projects for tribes. If you are interested in more information on the activities and experiences of the TGG members, please contact us at

THE Institute for Tribal Environmental Professionals (ITEP)

In 2014, ITEP began a cooperative agreement with EPA's Office of Environmental Information to provide tribal support for the NEIEN. In this capacity, ITEP works with the TGG and tribes, offering technical and programmatic support on Exchange Network topics.
