SEAL BEACH, CA – Clean Energy has been awarded a new three-year contract from the City of Phoenix Public Transit Department, AZ to supply the City's Valley Metro Transit Fleet with liquefied natural gas (LNG) fuel to power its fleet of 400-plus LNG buses. When the new contract takes effect July 1, 2009, Clean Energy will begin delivering approximately 6 million gasoline gallon equivalents of fuel annually to three fueling sites.

James Harger, senior vice president and chief marketing officer for Clean Energy said, "With this new contract, the City of Phoenix Valley Metro Fleet now ranks as our largest LNG customer. Overall at transit agencies across the nation, Clean Energy supplies natural gas fuel for 4,000 buses daily."

Harger added, "We are pleased to provide LNG fueling services to the City of Phoenix, ensuring that transit buses roll out daily to meet vital community transportation needs. Clean Energy is committed to helping reduce pollution and protect environmental quality in every community and region we serve, and we commend Valley Metro for their success at achieving these goals." Natural gas is one of the best ways to reduce air pollution and greenhouse gas emissions because it burns cleaner than diesel fuel.

The City of Phoenix Public Transit Department is a member of Valley Metro, an organization of 14 local governments that provides or funds transit services in the greater Phoenix metropolitan and surrounding areas. Phoenix deploys the largest fleet of clean-burning LNG transit buses in the U.S. to cover its 517 square miles of area plus neighboring cities.

It has a broad customer base in the refuse, transit, ports, shuttle, taxi, trucking, airport and municipal fleet markets, fueling more than 15,000 vehicles at 173 strategic locations across the United States and Canada.
