FOR IMMEDIATE RELEASE

PAA Provides Status Report on Phase I
Construction of St. James Terminal and
Announces Phase II Development

     (Houston — October 10, 2006) Plains All American Pipeline, L.P. (NYSE: PAA) today provided a status report on Phase I construction activities for its St. James Terminal facility in Louisiana. PAA also announced today that it is proceeding with the Phase II development of the St. James Terminal facility. Matrix Service Inc. of Tulsa, Oklahoma, will act as contractor for both phases of the project.

     The initial construction of the St. James Terminal, referred to as the Phase I development, commenced in mid-2005. The facility is anticipated to become operational during the first quarter of 2007 at a total cost of approximately $93 million. Phase I consists of seven crude oil storage tanks with an aggregate shell capacity of approximately 3.5 million barrels along with the manifold and pumping system.

     Under the Phase II project, Plains will construct approximately 2.7 million barrels of additional tankage at its crude oil storage and terminalling facility in St. James, Louisiana. The Phase II project will expand the total capacity of the facility to 6.2 million barrels and is expected to cost approximately $64 million. The Partnership estimates that the Phase II tankage will become operational during the first quarter of 2008.

     “Plains All American continues to invest in strategically located storage assets that we believe are well positioned to benefit from long-term trends in the energy industry,” said Greg L. Armstrong, Chairman and Chief Executive Officer of the Partnership. “We believe that foreign imports will continue to increase as a result of increased U.S. crude oil consumption and domestic crude oil production declines. Our St. James Terminal is ideally located to support our foreign crude oil import activities and will strengthen our ability to provide our refinery customers with foreign crude oil supply alternatives.”

     Armstrong noted that the Partnership preliminarily anticipates spending approximately $20 million to $22 million of the $64 million capital cost during 2006, with the majority of the remaining expenditures to be spent in 2007.

     Upon completion of the Phase II development, Plains All American’s St. James Terminal Facility will consist of one 210,000 barrel tank, four 480,000 barrel tanks, six 670,000 barrel tanks and a manifold and pumping system capable of receiving and delivering crude oil at the mainline flow rates of connecting carriers.
