Exhibit 99.1
Martin Midstream Partners Announces Sale of its Mont Belvieu
Railrack Facility to an Affiliate of Enterprise Products Partners L.P.
KILGORE, Texas, May 4, 2009/GlobeNewswire/ — Martin Midstream Partners L.P. (Nasdaq: MMLP)
announced today that it has completed the sale of its Mont Belvieu, Texas, natural gas liquids
(NGL) railroad unloading terminal to Enterprise Products Operating LLC, an affiliate of Enterprise
Products Partners L.P. (NYSE: EPD) for approximately $23.1 million.
The facility has been operated by MMLP or its predecessor since 1991 and has the capability to
unload refinery grade propylene (RGP) railcars and transport the RGP to the Enterprise Products
Operating Mont Belvieu facility via pipeline. As part of its 2008 organic growth plan, Martin
entered into an agreement with Enterprise to significantly enhance the existing railrack facility
by expanding its throughput capacity. Under the terms set forth in the sale agreement, Martin will
finish construction related to the expansion which is expected in June 2009.
Due to the economic downturn and limited access to the capital markets, MMLP has been
evaluating the potential divestiture of non-core assets such as this facility. The sale of this
facility will provide MMLP with improved liquidity and will result in a negligible loss of
distributable cash flow to MMLP.
The facility supplies Enterprise’s propane/propylene facility in Mont Belvieu, which is part
of the world’s largest NGL fractionation complex, and features approximately 100 million barrels of
liquids storage capacity.
