Transportation revenue is generated through a combination of tariffs, third-party pipeline capacity agreements and other transportation fees. The transportation segment also includes equity earnings from our investments in entities that own the Advantage, BridgeTex, Caddo, Cheyenne, Diamond, Eagle Ford, Midway, Saddlehorn, STACK and White Cliffs pipeline systems, as well as Settoon Towing.


As of December 31, 2017, Plains employed a variety of owned or leased long-term physical assets throughout the United States and Canada in the transportation segment, including approximately:

18,700 miles of active crude oil and NGL pipelines and gathering systems
32 million barrels of active, above-ground tank capacity used primarily to facilitate pipeline throughput and help maintain product quality segregation
60 transport and storage barges and 30 transport tugs
810 trailers (primarily in Canada)
