(a) Upon motion by a party, a conference of the parties may be convened to adjust or settle the proceedings, set schedules, delineate issues, stipulate certain issues of fact or law, set procedures, and consider other relevant matters where it appears that a conference will materially advance the proceeding. The Assistant Secretary or presiding official may delineate the issues which are to be considered and may place appropriate limitations on the number of intervenors who may participate, if two or more intervenors have substantially like interests.

(b) A motion by a party for a conference shall include a specific showing why a conference will materially advance the proceeding.

(c) Conferences shall be recorded, unless otherwise ordered by the Assistant Secretary or presiding official, and the transcript shall be made a part of the official record of the proceeding and available to the public.
