341.4—Filing requirements for amendments to tariffs.
(a) Supplements to tariffs.
(1)
Supplements are limited to one effective supplement per tariff, except for cancellation, postponement, adoption, correction, and suspension supplements.
(2)
Item numbers that are canceled or amended must be identified and brought forward with the item title in the current supplement. Reissued items from prior supplements must be brought forward in the current supplement and referenced with the symbols in § 341.3(b)(10)(i). Cancellation of an item by supplement must be made by bringing forward the item number with an added capital letter suffix in alphabetical sequence. For example: “Item 445-A cancels Item 445.” If a canceled, withdrawn, or expired item is subsequently reissued, it must be republished under the same item number with the next letter suffix.
(b) Cancellation supplements.
Cancellation supplements must be filed when tariffs are canceled without reissue.
(d) Adoption supplements.
A supplement adopting the tariff of another carrier must be filed to provide the notice required in § 341.6.
(e) Correction supplements.
Correction supplements must be filed to correct typographical or clerical errors. Three correction supplements are permitted per tariff.
(f) Suspension supplements.
A suspension supplement must be filed for each suspended tariff or suspended part of a tariff within 30 days of the issuance of a suspension order. The suspension supplement must be served on all subscribers. The supplement must include the date it is issued, a reproduction of the ordering paragraphs of the suspension order, a statement that the tariff or portion of the tariff was suspended until the date stated in the suspension order, a reference to the docket number under which the suspension order was issued, and a statement that the previous tariff publication remains in effect.
