(a) Suspended matter not to be used. A fare, charge, or other tariff provision which is suspended by the Department, under authority of chapter 415 of 49 U.S.C. Subtitle VII, shall not be used during the period of suspension specified by the Department's order.

(b) Suspended matter not to be changed. A fare, charge, or other tariff provision which is suspended by the Department shall not be changed in any respect or withdrawn or the effective date thereof further deferred except by authority of an order or special tariff permission of the Department.

(c) Suspension continues former matter in effect. If a tariff publication containing matter suspended by the Department directs the cancellation of a tariff or any portion thereof, which contains fares, charges, or other tariff provisions sought to be amended by the suspended matter, such cancellation is automatically suspended for the same period insofar as it purports to cancel any tariff provisions sought to be amended by the suspended matter.

(d) Matter continued in effect not to be changed. A fare, charge, or other tariff provision which is continued in effect as a result of a suspension by the Department shall not be changed during the period of suspension unless the change is authorized by order or special tariff permission of the Department, except that such matter may be reissued without change during the period of suspension.

(a) Suspension supplement. Upon receipt of an order of the Department suspending any tariff publication in part or in its entirety, the carrier or agent who issued such tariff publication shall immediately issue and file with the Department a consecutively numbered supplement for the purpose of announcing such suspension.

(b) The suspension supplement shall not contain an effective date and it shall contain the suspension notice required by paragraph (c) of this section.

(c) Suspension notice. The suspension supplement shall contain a prominent notice of suspension which shall:

(1) Indicate what particular fares, charges, or other tariff provisions are under suspension,

(2) State the date to which such tariff matter is suspended,

(3) State the Department's docket number and order number which suspended such tariff matter, and

(4) Give specific reference to the tariffs (specifying their D.O.T. or other identifying numbers), original or revised records and paragraphs or provisions which contain the fares, charges, or other tariff provisions continued in effect.

When tariff provisions continued in effect by a suspension are reissued during the period of such suspension, the termination of the suspension and the coming into effect of the suspended matter will not accomplish the cancellation of such reissued matter. In such circumstances, prompt action shall be taken by the issuing agent or carrier to cancel such reissued provisions upon the termination of the suspension in order that they will not conflict with the provisions formerly under suspension.

(a) When the Department vacates an order which suspended certain tariff matter in full or in part, such matter will not become effective until the termination of the suspension period unless the issuing agent or carrier amends the pertinent tariffs in the manner prescribed in this subpart (except as provided in paragraph (b) of this section).

(b) If the Department vacates its suspension order prior to the original published effective date of the tariff provisions whose suspension is vacated, such provisions will become effective on their published effective date.

(a) Endeavor to cancel prior to expiration of suspension period. When an order of the Department requires the cancellation of tariff provisions which were suspended by the Department and such cancellation is required to be made effective on or before a date which is after the date to which such tariff provisions were suspended, the issuing carrier or agent shall, if possible, make the cancellation effective prior to the date to which such tariff provisions were suspended.

(b) When necessary to republish matter continued in effect by suspension. If suspended tariff provisions become effective upon expiration of their suspension period and thereby accomplish the cancellation of the tariff provisions continued in effect by the suspension, the issuing agent or carrier shall republish and reestablish such canceled tariff provisions effective simultaneously with the cancellation of the suspended provisions in compliance with the Department's order. The tariff amendments which reestablish such canceled tariff provisions shall bear reference to this subpart and the Department's order.
