Enterprise Continues to Expand Petrochemical Assets in Southeast Texas.

HOUSTON -- Enterprise Products Partners L.P. (NYSE:EPD) today announced that it will expand its 48-mile refinery grade propylene (RGP) pipeline system between Texas City and Mont Belvieu, Texas. The expanded pipeline will provide Enterprise with access to increasing volumes of RGP from the Texas City area for transportation, storage and fractionation at its Mont Belvieu facilities. The pipeline, with current capacity of 23,000 barrels per day (BPD), will increase to 32,000 BPD with the installation of additional pumps by the fourth quarter of 2007.

Additionally, two other petrochemical infrastructure projects, announced in March 2006, are on schedule. Enterprise is nearing completion of a project to interconnect its recently acquired 66-mile, 50,000 BPD RGP pipeline with a refinery in the Beaumont /Port Arthur, Texas, area and Enterprise's Mont Belvieu propylene fractionator and storage facilities. This project is expected to be operational in January 2007 and the pipeline will be further expanded with an additional interconnect to a second Beaumont / Port Arthur area refinery in late 2007. Additional RGP volumes from the second interconnect are expected by early 2008.

Further, Enterprise is also on schedule with the construction of a fourth propylene fractionator at its Mont Belvieu facility. The new splitter, which is slated to be in service during the third quarter of 2007, will increase the partnership's propylene/propane fractionation capacity from 58,000 BPD currently to about 73,000 BPD, which represents an additional 1 billion pounds of polymer grade propylene per year. Polymer grade propylene is 99.5 percent pure propylene and is used in the production of plastic consumer products, pharmaceuticals, detergents and solvents. Increased access to RGP supplies through both the new Beaumont /Port Arthur RGP pipeline and the expanded Texas City RGP pipeline are expected to be available for fractionation at the expanded splitter facility.
