Sec.  1.744   Amendments.

   (a) Any application not designated for hearing may be amended at any time by
   the filing of signed amendments in the same manner, and with the same number
   of copies, as was the initial application. If a petition to deny (or to
   designate for hearing) has been filed, the amendment shall be served on the
   petitioner.

   (b) After any application is designated for hearing, requests to amend such
   application may be granted by the presiding officer upon good cause shown by
   petition, which petition shall be properly served upon all other parties to
   the proceeding.

   (c) The applicant may at any time be ordered to amend his application so as
   to make it more definite and certain. Such order may be issued upon motion
   of the Commission (or the presiding officer, if the application has been
   designated for hearing) or upon petition of any interested person, which
   petition shall be properly served upon the applicant and, if the application
   has been designated for hearing, upon all parties to the hearing.
