(1) Following a prehearing conference the commission may issue a procedural order which fixes any dates which are pertinent to the disposition of the case, and which sets out the procedures to be followed by the parties. Subsequent orders modifying the original procedural order may also be issued.

(2) The procedural order may include a description of the matters discussed at and the actions taken pursuant to the prehearing conference. A proposed form of notice for the hearing may be attached to the order. If objections to the proposed notice are not received within a specified time, it shall be deemed to be approved by the parties.

(3) If a procedural order is entered which specifies either procedures or times for the disposition of a case, such as the timing of discovery and data requests, which are different from the procedures and times set forth in these rules, the procedural order shall control.
