49 U.S.C. § 15701 — Providing transportation and service

(a) Service on Reasonable Request. A pipeline carrier covered by this part must provide transportation or service whenever someone makes a reasonable request for it. (b) Rates and Other Terms. The carrier must also give anyone, on request, its rates and other service terms. It must respond either (1) in writing, sent promptly after it gets the request, or (2) promptly made available electronically. (c) Limitation on Rate Increases and Changes to Service Terms. The carrier cannot raise its common carrier rates or change its common carrier service terms right away. It must first give written or electronic notice, and wait 20 days, before the change takes effect — but only for people who, in the past 12 months, either (1) asked for those rates or terms under subsection (b), or (2) arranged a shipment that the new rates or terms would affect. (d) Provision of Service. The carrier must actually provide transportation and service according to the rates and terms — and any changes to them — that it published or made available under subsections (b) or (c). (e) Regulations. The Board must write regulations to carry out this section. Those regulations must require the carrier to immediately disclose and share its rates, service terms, classifications, rules, practices, and their effective dates. The regulations may change the 20-day waiting period from subsection (c). The Board had to finish these regulations within 180 days after January 1, 1996.
