Up to eight vehicles in the city's public works department could be running on natural gas in the future if an application for a $100,000 state grant wins approval.

The City Council has told representatives of Natural Gas Resources of Utah Inc. that the city will allow the company to make the conversions if the grant is approved by the Utah Energy Office. But they cautioned that it is an all or nothing arrangement. If the city does not received the grant, none of the vehicles will be converted.The project includes installation of a natural-gas service station. The station would feature a slow-fill operation in an overnight process. The vehicles would have dual systems to allow operation on gasoline if the natural gas runs out or the conversion system malfunctions.

Natural gas is almost pollution free and technological improvements in recent years yield mileage and performance ratings close to those of regular gasoline-powered engines.
