On his or her own motion, or on the motion of any party, the
administrative law judge may direct that there be a restricted access
portion of the record to contain any material in the record to which
public access is restricted by law or by the terms of a protective order
entered in the proceedings. This portion of the record shall be place in
a separate file and clearly marked to avoid improper disclosure and to
identify it as a portion of the official record in the proceedings.
