49 CFR 1305.2 - Disclosure requirement for existing rates.
(a) A pipeline carrier must disclose to any person, on request, the specific rate(s) requested (or the basis for calculating the specific rate(s)), as well as all charges and service terms that may be applicable to transportation covered by those rate(s).
(b) The information provided by a pipeline carrier under this section must be provided immediately. (It is expected that the response will be sent within hours, or at the latest by the next business day, in most situations.) Such information may be provided either in writing or in electronic form, as agreed to by the parties. If the parties cannot agree, such information is to be provided in electronic form where both parties have the requisite capabilities; otherwise, it is to be provided in writing.
(c) A pipeline carrier may, at its option, require that all requests submitted under this section be in writing or electronic form, or the carrier may permit oral requests.
