What is a periodic review and evaluation?
A periodic review and evaluation is an examination the Secretary performs to monitor a Tribe's performance of activities associated with the development of energy resources and to review compliance with a TERA. During the TERA consultation, a Tribe and the Secretary will develop a periodic review and evaluation process that addresses the Tribe's specific circumstances and the terms and conditions of the Tribe's TERA. The Tribe will include the agreed-upon periodic review and evaluation process in its final proposed TERA.
