The Commission reviews applications for a minor alteration, helps build the record, and the Commissioners make the final decision about whether to issue a site or route permit.

Department of Commerce – Energy Environmental Review and Analysis
A minor alteration is defined as a change in a large electric power generating plant or high voltage transmission line that does not result in significant changes in the human or environmental impact of the facility. A permittee requesting a minor alteration must submit an application to the Commission describing the modifications to be made and an explanation why the alteration is minor. Upon receiving an application for a minor alteration the Commission is required to provide at least a 10-day period for interested persons to submit comments on the request. After close of the comment period the Commission must decide whether to authorize the minor alteration and impose reasonable conditions as necessary, or determine that the alteration is not minor and requires a full permitting decision. If the Commission decides a proposed alteration is a minor alteration, it may determine whether additional conditions are appropriate.
