The agency may change the time or place of the hearing if necessary, or in response
                  to a written request from a party to the hearing. Forward any such request to the
                  agency immediately, and by email, if necessary. If the request is made orally, help
                  prepare a letter to the agency stating reasons for the request. If advisable, send
                  the agency a memorandum stating whether the request seems justified.
               
               If the agency grants the request, cancel the former arrangements and make new arrangements
                  as the agency directs. Notify the agency promptly of the new arrangements, so the
                  agency may issue Form HA-508 (Amended Notice of Hearing) to all parties immediately.
