CalEPA Tribal Consultation Policy

CalEPA first adopted its Tribal Consultation Policy in 2009 to guide CalEPA and all its BDOs in their daily operations to work with California Native American Tribes in a knowledgeable, sensitive, and respectful manner.  In August 2015, CalEPA revised and updated the Tribal Consultation Policy to strengthen and enhance the objectives outlined in this agency-wide guidance document. The 2015 CalEPA Policy on Consultation with California Native American Tribes (PDF) details how CalEPA and its BDOs will continue to work to improve and strengthen its relationships with Tribal governments and Tribal communities.  Please refer to the Tribal Policy Revision Background page to find out more about how our Tribal Consultation Policy was revised.

CalEPA implements our Tribal Policy with the assistance of our Tribal Advisory Committee, made up of representatives from federally and non-federally recognized Tribes, and the input of interested Tribal governments, communities, and stakeholders.
