EPA works to protect human health and the environment of federally recognized tribes by supporting implementation of federal environmental laws, with a special emphasis on helping tribes administer their own environmental programs. These efforts are consistent with the federal trust responsibility, the government-to-government relationship, and EPA's 1984 Indian Policy.
