SEAL BEACH, Calif., Jul 28, 2008 (BUSINESS WIRE) -- Clean Energy Fuels Corp. (Nasdaq: CLNE) has been awarded a one-year LNG (liquefied natural gas) supply contract renewal with an option for up to two additional years to provide fuel for the City and County of Sacramento's growing fleets of natural gas-powered refuse trucks.
