Prior to the commercial generation of electricity, an application for a Commercial Use Permit is submitted on a Sundry Notice form and approved by BLM prior to any commercial operations from a Federal geothermal lease, a Federal Unit, or a production facility. This document describes the location of all wells, allocation of that production, location of meters, allocation of schedules, power purchase agreement, and a number of other items. It generally takes about a month for BLM approval of a Commercial Use Permit.
