Region 10 of the Environmental Protection Agency consists of Alaska, Idaho, Oregon and Washington State. The primary function of the Regional Tribal Operations Committee (RTOC) is a partnership with the United States Environmental Protection Agency to further Tribal environmental objectives at the regional level, to serve as a liaison between the EPA and Tribes regarding information exchange, and to provide assistance to the National Tribal Operations Committee (NTOC).

Our mission is to protect and improve Tribal health and environmental conditions affecting Federally Recognized Tribes consistent with the United States Environmental Protection Agency (EPA) Indian Lands Policy, EPA’s trust responsibility, environmental laws, policies and guidance.
