Centennial Pipeline announces beginning of full operation

HOUSTON, March 15, 2002 — Centennial Pipeline on Friday announced its interstate pipeline is targeted for full operation by April 1, and it is now accepting nominations for the transportation of refined petroleum products from the U.S. Gulf Coast to the Midwest.

“The Centennial Pipeline will provide shippers with a significant amount of new capacity for refined petroleum products transportation to key Midwestern markets, making it possible for shippers to directly connect major refineries and import terminals located in the U.S. Gulf Coast to the Midwest,” said Christopher A. Helms, president of Centennial Pipeline LLC.

The 795-mile Centennial Pipeline will initially have the capacity to transport more than 210,000 barrels per day of refined petroleum products, including gasoline, diesel fuel, and jet fuel and can be expanded to transport more than 320,000 barrels per day. Shippers on the Centennial Pipeline can deliver refined petroleum products from origination points along the U.S. Gulf Coast to Midwest markets served by the Marathon Ashland Pipe Line and TEPPCO systems, as well as to markets further east that are served by those same systems.
