Enterprise Products Partners L.P. (NYSE:EPD) announced today that it is conducting a two-week supplemental open commitment period to accommodate additional shipper demand on the partnership's Appalachia to Texas pipeline ("ATEX Express"). Earlier this month, Enterprise announced that it had received sufficient long-term transportation commitments to move forward with development of the 1,230-mile ATEX Express pipeline, which will deliver growing ethane production from the Marcellus/Utica Shale areas of Pennsylvania, West Virginia and Ohio to the U.S. Gulf Coast.

"Since our announcement to proceed with development of the ATEX Express pipeline, we have received multiple inquires from producers seeking transportation capacity," said A.J. "Jim" Teague, executive vice president and chief operating officer of Enterprise's general partner. "We will use this extended open commitment period to execute additional binding, 15-year transportation agreements."

The open commitment period begins today at 9 a.m. CST and will close on Monday, January 23, 2012 at 5 p.m. CST. For commercial inquiries or additional information related to the open commitment period, please contact Russ Kovin at (713) 381-7925 or rkovin@eprod.com.
