Dublin took another step toward reducing its carbon footprint this week.

Dublin took another step toward reducing its carbon footprint this week.

A $1.7-million contact for the construction of a compressed-natural-gas fueling station at the Shier Rings Road fueling facility was awarded to the lowest bidder, the R.W. Setterlin Building Co.

The CNG fueling project includes the "installation of the natural-gas compressors and fuel dispensers, as well as making modifications to the existing fleet-maintenance facility to allow for the maintenance and repairs of CNG vehicles," the staff report to council states.

The project also will mean the purchase of 44 CNG vehicles, which would replace gasoline- or diesel-fueled city vehicles.

"The vehicles we are purchasing are vehicles scheduled for replacement," City Manager Marsha Grigsby told council.

Dublin's 2012-16 capital-improvement program set $2.18 million aside for the CNG project that includes "the compressor equipment, design of the facility modifications, the construction to install the equipment and modify the facility and other minor costs," the staff report states.

The vehicle purchase and construction of the CNG fueling facility will not be completely city-funded.

Dublin received a $1.5-million grant from the U.S. Department of Energy and will use a little more than $1 million on the construction of the fueling facility and modifications. The rest of the grant money will be used to purchase the 44 CNG vehicles.

Dublin also received a $275,000 grant from IGS Energy for the project.

CNG-burning vehicles typically are cleaner-burning machines than gasoline or diesel vehicles.

When Ron Burns, Dublin's director of streets and utilities, presented the project to council in August, he said CNG vehicles would give the city 25 percent to 30 percent fewer emissions than gasoline.

The project also would help save the city money, he said.

During a July council meeting, Burns said CNG, which will be provided by IGS Energy, would cost about $1.13 per gallon. Dublin initially anticipated $20,000 in fuel savings in the first year.

In other matters, council approved the $95,325 purchase of 0.667 acre at 5551 Avery Road.

According to the staff report to council, that land will be used for the future widening of Avery Road, as laid out in 1996.

The city already has purchased two other Avery Road properties for the project.
