1. No such common carrier in its operations as such shall discriminate against or between shippers in regard to facilities furnished or service rendered or rates charged under the same or similar circumstances in the transportation of crude oil or petroleum; nor shall there be any discrimination in the transportation of crude oil or petroleum produced or purchased by itself, directly or indirectly. In this connection, the pipeline shall be considered as a shipper of the crude oil or petroleum produced or purchased by itself, directly or indirectly, and handled through its facilities.
2. No such carrier in its operations shall directly or indirectly charge, demand, collect or receive from anyone a greater or less compensation for any service rendered than from another for a like and contemporaneous service; but this shall not limit the right of the Commission to prescribe rates and regulations different from or to some places from other rates or regulations for transportation from or to other places, as it may determine; nor shall any carrier be guilty of discrimination when obeying any order of the Commission.
3. When there shall be offered for transportation more crude oil or petroleum than can be immediately transported, the common carrier shall transport oil from each person and producer ratably, in proportion to the average daily production; but no such common carrier shall be required to receive for shipment from any person, firm, corporation or association of persons more than 3,000 barrels of crude oil or petroleum in any 1 day.
