(c) At all points where tariffs are maintained, they shall be made available for inspection by any person during the carrier's normal business hours. The tariffs shall be accessible and readable. The carrier shall also display, in a conspicuous place in those locations, a notice, in large print, which contains a statement that the tariffs are available for public inspection.
(d) At all other carrier business offices, the carrier shall display a notice advising the public of the location of the nearest available tariff. The notice shall be in large print and posted in a conspicuous place. In addition, the carrier shall, upon request, make its tariffs available at that location as soon as possible but not later than within 20 days, or provide the sought information orally if satisfactory to the requestor.
(e) Any publication referred to in a tariff must be maintained with that tariff.
(f) If any tariff maintained pursuant to paragraph (b) of this section has not been used for a substantial length of time, the availability of that tariff, including its reissues, may be discontinued at that office until such time as it is again requested. It shall then be made available within 20 days.
