National Tribal Caucus (NTC)

The National Tribal Caucus (NTC) is a national body of high-level tribal representatives who work with the EPA to exchange views, information, and advice on EPA's tribal programs. Members are selected on a regional basis by each Regional Tribal Operations Committee (RTOC) or its equivalent. Their primary focus is to identify and address tribal environmental issues that are national in scope, cross-agency or cross-media in nature, or that may be emerging or urgent.
