Prehearing conferences and orders.

The presiding officer may order a prehearing conference and may enter such prehearing orders as the presiding officer determines are appropriate for the efficient conduct of the hearing, including, without limitation: 1. The exchange of written direct testimony of witnesses; 2. The exclusion of particular testimony or evidence; 3. The admission of particular testimony and other exhibits by agreement of the parties; 4. The advance marking of all exhibits; 5. The exchange by the parties of written prehearing statements or briefs similar to pretrial statements filed in district court; and 6. Settlement negotiations. Settlement negotiations, and the statements of parties relating thereto, made at a prehearing conference are not admissible in evidence at the hearing unless the parties agree and the agreement is incorporated in a prehearing order.
