The Secretary's receipt of a qualified Tribe's complete application begins a 270-day statutorily mandated period during which the Secretary must approve or disapprove a proposed TERA. The TERA takes effect upon the 271st day after the Secretary's receipt of a complete application from a qualified Tribe, unless the Secretary approves the TERA to take effect on an earlier date, or the Secretary disapproves the application before that date.
