Enterprise Begins Service on New Propylene Fractionator at Mont Belvieu, Texas Facility.

HOUSTON -- Enterprise Products Partners L.P. (NYSE:EPD) today announced that its fourth propylene fractionator has been installed at the partnership's Mont Belvieu, Texas complex and is now in service. The new unit allows Enterprise to increase its production of polymer grade propylene (PGP) at the facility by 26 percent from 3.8 billion pounds per year, or 58,000 barrels per day (BPD), to approximately 4.8 billion pounds per year, or 73,000 BPD. With the additional 1 billion pounds, Enterprise's Mont Belvieu facility now accounts for more than 19 percent of the domestic PGP manufacturing capacity. PGP is used in the production of plastic consumer products, pharmaceuticals, detergents and solvents.

"The successful expansion of our Mont Belvieu complex comes at a time when global demand for propylene is growing, and also reflects our commitment to investing in infrastructure that helps meet the needs of our customers and provides a reliable source of incremental cash flow for our investors," said Michael A. Creel, Enterprise president and chief executive officer. "Domestic refinery expansions and global economic growth are expected by industry experts to generate five to six percent annual growth in worldwide demand for propylene."

Complementing the partnership's fractionation facilities is an extensive network of pipelines that gathers product for delivery to Mont Belvieu and transports fractionated products to major refiners and leading petrochemical companies for use as feedstocks, in addition to providing access to storage facilities. As part of the plan to enhance the capabilities of these assets, Enterprise is expanding its 48-mile refinery grade propylene (RGP) pipeline between Texas City, Texas and Mont Belvieu in order to provide the partnership with access to growing volumes of RGP originating in the Texas City area. This pipeline project is scheduled for completion in the fourth quarter of 2007.

Enterprise has also completed the process of connecting a Beaumont/Port Arthur, Texas area refinery to the partnership's propylene fractionation and storage facilities at Mont Belvieu via its 66-mile, 8-inch diameter pipeline. In the first quarter of 2008, Enterprise expects to connect the pipeline to a second Beaumont/Port Arthur refinery. These expansion initiatives are expected to add 50,000 barrels per day of gathering capacity into Mont Belvieu.

The partnership is also in the process of evaluating economic alternatives for its least efficient propylene fractionator at Mont Belvieu, which was constructed in 1978. Alternatives include taking the unit out of service until pipeline connections are completed in the first quarter of 2008, or using it as part of the partnership's natural gas liquids fractionation business. A final decision is expected by the fourth quarter of 2007.
