49 U.S.C. § 15301 — General pipeline jurisdiction

(a) In general: The Board has jurisdiction over transportation by pipeline — or by pipeline combined with railroad or water — when the commodity moved is something other than water, gas, or oil. This jurisdiction covers transportation within the United States that moves between: (1) one state and another state; (2) one place in the District of Columbia and another place in the District of Columbia; (3) a state and a U.S. territory or possession; (4) one U.S. territory or possession and another; (5) two places within the same U.S. territory or possession; (6) the United States and another place in the United States, passing through a foreign country; or (7) the United States and a place in a foreign country. (b) No jurisdiction over intrastate transportation: The Board has no jurisdiction under subsection (a) over property transportation, or the receiving, delivering, storing, or handling of property, that happens entirely within one state (other than D.C.) and isn't moving between the U.S. and a foreign country — except where this part says otherwise. (c) Protection of states' powers: This part does not limit a state's police power to require reasonable in-state transportation from carriers under the Board's jurisdiction, unless the state's requirement conflicts with a Board order under this part, or this part forbids it.
