This bill establishes the Office of Indian Affairs as a cabinet agency under the governor of Washington, outlining its responsibilities to foster relationships with federally recognized Indian tribes, tribal organizations, and urban Indian organizations. The office will assist the governor in policy development, provide training for state employees on effective communication with tribal nations, advise state agencies on tribal issues, and facilitate meetings with tribal leaders to implement the Centennial Accords. The executive director of the office will be appointed by the governor and will oversee staff to fulfill the office's objectives.

Additionally, the bill emphasizes that the creation of the Office of Indian Affairs does not infringe upon the sovereignty of federally recognized tribes and affirms that these tribes can enact their own laws. The office is authorized to establish procedures for operations and expenditures to enhance state-tribal relations and may accept grants or gifts for this purpose. An annual report detailing the office's activities, budget, and achievements will be submitted to the governor and legislature, ensuring transparency and accountability.
