(c) The amendment of any sheet of a tariff shall be made only by reissuing the particular sheet upon which the change, addition, or cancellation is made. Reissuing the sheet means to cancel it by a new tariff sheet that contains the same tariff provisions except whatever additions, changes, or cancellations are made. Each revised tariff sheet must bear the same sheet number, either spelled out or in numerical format as the sheet it amends and must bear a consecutive revision number as explained in this subsection. A revised tariff sheet that amends an original sheet must be designated "FIRST REVISION OF SHEET ... ," "SECOND REVISION OF SHEET ... ," etc. Each revised sheet must direct the cancellation of the original or revised sheet that it amends and this cancellation may be shown in the manner indicated in the following example: FIRST REVISION OF SHEET ....
CANCELLING
ORIGINAL SHEET ....
When the first revision of a sheet is to be amended, it must be cancelled by a second revised sheet in the following manner:
SECOND REVISION OF SHEET ....
CANCELLING
FIRST REVISION OF SHEET ....
The same number formatting must be used consistently throughout the tariff.
