The survey shall also include the classification for trainee in all trades.
(2) The Tribe shall retain for not less than three (3) years the names and addresses of all sources contacted and the wage rates reported by each source.

(5) In the years the Tribe does not conduct a survey, the wage rates shall be adjusted pursuant to the published rise in the Cost of Living Index for the area.
(B) Delegation of Authority. The Tribe may delegate its authority to conduct surveys and/or to establish the Tribal prevailing wage under this chapter to an agent or agency of the Tribe, including, but not limited to, the Tribal Employment Rights Organization (TERO); however, the Council shall approve the schedule of prevailing wages at least annually by motion or resolution.
