Questar : Fueling announces the opening of its CNG-fueling station in Buttonwillow, Calif.

BUTTONWILLOW, Calif. - Questar Fueling Company, a subsidiary of Questar Corporation (NYSE:STR), has opened its newest compressed natural gas (CNG) fueling station in Buttonwillow, Calif. Given its operations in the area, PepsiCo's Frito-Lay CNG fleet will serve as the initial customer base for this fast-fill CNG fueling station. The station also will make fuel available for other companies currently using or considering using alternative-fuel vehicles.

'We are pleased to help facilitate Frito-Lay's efforts to create the most fuel-efficient fleet possible,' said Carl Galbraith, general manager for Questar Fueling. 'Our transportation customers want clean fuels like reliable, low-cost natural gas for their fleets and they don't have time for delays. That's why our high-speed, high-volume CNG-fueling stations have captured their attention. Some of the nation's largest fleet operators, including Frito-Lay, are leveraging clean-burning natural gas, and we're committed to developing the CNG-fueling infrastructure that keeps them on the road.'

This is Questar Fueling's first CNG station in California. The company has plans to build a second station in Fontana by year end. The company recently opened two stations - one in Salt Lake City and another in Phoenix. Over the past three years, the company has built 10 stations along major U.S. transportation corridors in Texas, Kansas, Arizona, Colorado and Utah. Along with an affiliate company, Questar currently owns and operates more than 37 CNG stations in Utah, Wyoming, Kansas, Texas, Arizona and Colorado. Companies such as Frito-Lay, Anheuser-Busch, Swift Transportation, Central Freight Lines, Dart Transit and many others operating medium- and heavy-duty trucks are finding it easier to fill up with natural gas. The new California CNG station offers four high-speed fueling lanes for large trucks. The station will also be open to members of the general public who drive natural gas-powered vehicles. The price for CNG is currently about $2 per equivalent gallon compared to about $2.165 per gallon of diesel fuel.

There are more than 15 million natural gas vehicles on the road worldwide - but only 140,000 are in the United States. Now that the United States has become the world's largest natural gas producer, the transportation industry is accelerating its integration of natural gas-powered trucks.
