(b) If an evidentiary hearing is convened, and a hearing for oral argument is requested, the Office of Hearings and Appeals shall determine whether the hearing for oral argument shall be held in conjunction with the evidentiary hearing or at a separate time.

(c) A hearing for the purpose of receiving oral argument will generally be conducted only after the issues involved in the proceeding have been delineated, and any written material which the Office of Hearings and Appeals has requested to supplement a Statement of Objections or Responses has been submitted. The presiding officer may require further written submissions in support of any position advanced or issued at the hearing, and shall allow responses any such submissions.
