Enterprise Completes Final Phase of Mid-America Pipeline Expansion.

Production at Enterprise-owned Independence Hub tops 400 million cubic feet per day

HOUSTON -- Enterprise Products Partners L.P. (NYSE:EPD) today announced it has placed into service the remaining part of its 50,000 barrels per day (BPD) expansion of the Rocky Mountain portion of the partnership's Mid-America Pipeline (MAPL) system. The project involved the installation of new pumps and modification of existing equipment at 20 pump stations along the approximately 2,500-mile system, increasing capacity by 20,000 BPD. The initial 30,000 BPD of additional capacity, which was created by looping more than 160 miles of pipelines, went into service in April of 2007. Combined, the two initiatives increase capacity on MAPL's Rocky Mountain system from 225,000 BPD to 275,000 BPD.

"The completion of this project represents another milestone in our Rockies growth initiative and enhances our ability to transport growing volumes of natural gas liquids originating from the nation's most prolific producing regions, including major basins in Colorado, Wyoming, Utah and New Mexico," said Michael A. Creel, Enterprise president and chief executive officer. "The increased capabilities provided by the expansion complement our integrated energy value chain strategy and will help ensure a steady supply of NGLs to Enterprise's recently completed Hobbs fractionator in Gaines County, Texas. The expansion will also enhance our ability to accommodate NGL volumes from the new Meeker gas processing plant in the Piceance Basin of northwest Colorado, which is expected to be in service during the next few weeks, as well as our new Pioneer cryogenic facility near Opal, Wyoming, which is on schedule to begin operations by the end of the year."

Creel added that the MAPL expansion is supported by significant shipper dedications and has been designed so that incremental capacity can be added efficiently and cost effectively.

In addition to the Rockies project, the partnership also completed an expansion of its MAPL system between Conway, Kansas and Skellytown, Texas during the second quarter of this year. The project involved construction of approximately 190 miles of 12-inch diameter pipeline and the installation of additional compression. As a result, the capacity for mixed NGLs between Conway and Skellytown increased by 67,000 BPD, while 48,000 BPD of incremental capacity is now available between Skellytown and the Hobbs Station, adjacent to Enterprise's new fractionation complex.

Creel stated, "The additional capacity will not only increase transportation revenues for the partnership, but will significantly reduce, or possibly eliminate, the need for shipper allocation on a portion of the MAPL system where volumes have been prorated almost continuously since it was acquired by Enterprise in 2002. The expansion also gives us bi-directional capabilities to move products north, as well as south, significantly increasing volumes of NGLs and purity products into the Conway hub, the second-largest domestic NGL market, while providing shippers with additional flexibility to manage their product inventories and access the most attractive markets."

Enterprise also announced today that production through the partnership's Independence Hub natural gas platform in the deepwater Gulf of Mexico has reached 440 million cubic feet per day from nine wells. As the initial 15 wells are brought on line, producers expect that production at the Independence Hub will reach its capacity of 1 billion cubic feet per day by the end of 2007.

Located in 8,000 feet of water, the record-setting Independence Hub, which was conceived, designed and constructed by Enterprise, is the deepest offshore platform ever installed in the Gulf and is also the largest in terms of processing capability. The Independence Hub is owned 80 percent by Enterprise, with Helix Energy Solutions Group, Inc. owning the remaining 20 percent. Enterprise owns 100 percent of the 134-mile Independence Trail pipeline, which transports natural gas from the Hub to the partnership's West Delta 68 platform for delivery to shore via a third party pipeline.
