Sec. 61.57  Cancellations.

    The following paragraphs govern the cancellation of tariffs and 
supplements.
    (a) By tariff or supplement. A carrier may cancel any tariff or 
supplement in whole or in part by another tariff or supplement. 
Cancellation of a tariff automatically cancels every supplement to that 
tariff, except a cancelling supplement.
    (b) By expiration. Subject to Sec. 61.59, a carrier may cancel a 
tariff or supplement in whole or in part by fixing a date on which the 
rates or regulations will expire.
    (c) Indication of. (1) A carrier which cancels a tariff or 
supplement in whole by another tariff or supplement must comply with 
Sec. 61.54(b)(1). Cancellation of tariffs or supplements in whole by 
expiration must be indicated as provided in Sec. 61.54(b)(3).
    (2) Where a carrier issues a tariff, supplement, or revised page 
partially cancelling another tariff, supplement, or revised page, it 
must specifically state what portion of the other tariff publication is 
cancelled. Such other tariff or supplement must at the same time be 
correspondingly amended, effective on the same date.
    (3) When only a part of tariff or supplement is to expire, a carrier 
must show the expiration date on the same page, and associate it with 
the matter which is to expire. Changes in expiration date must be made 
pursuant to the notice requirements of Sec. 61.58, unless otherwise 
authorized by the Commission. Expirations must be indicated as follows:


Expires at the end of -------------------- (date) unless sooner 
cancelled, changed or extended.


    (d) Rates and regulations to apply. When a carrier cancels a tariff 
or supplement in whole or in part by another tariff or supplement, the 
cancelling publication must show where all rates and regulations will be 
found, or what rates and regulations will apply.
    (e) Omissions. When a tariff or supplement cancelling a previous 
tariff or supplement omits points of origin or destination, rates or 
regulations, or routes, which were contained in such tariff or 
supplement, the new tariff or supplement must indicate the omission in 
the manner prescribed in paragraph (c) of this section. If such 
omissions effect changes in rates of regulations, that fact must be 
indicated by the use of the uniform symbols prescribed in 
Sec. 61.54(i)(1).
    (f) Carriers ceasing operations. When a carrier ceases operations 
without a successor, it must cancel its tariffs pursuant to the notice 
requirements of Sec. 61.58, unless otherwise authorized by the 
Commission.
