Tariffs, changes.
Companies may change filed tariffs by one of two methods:
(1) Issuing revised pages to the tariff. A revised page must have the same page number as the page it cancels. For example: "1st revised page 1" cancels "Original page 1."
(2) Issuing complete new tariffs. Each of the pages in a new tariff must be identified as an original page. For example: "Original Page 1," "Original Page 2," and so on.
