Environmentally-Friendly Machines and School Buses

In 2012 the Hall County school system became the first Georgia school district to fuel its fleet with clean-burning propane autogas. The school district purchased twenty (and later ten more) Blue Bird® propane-powered Vision school buses fueled by domestically produced propane autogas to reduce the community’s carbon footprint and lower the county’s costs for school bus fuel and maintenance. Bibb County also purchased thirty-one propane school buses.

The 72-passenger Blue Bird® Propane-Powered Visions, manufactured in Georgia, features a ROUSH™ CleanTech liquid propane autogas fuel system, which reduces nitrogen oxide, carbon monoxide, and total hydrocarbons emissions, and virtually eliminates particulate matter, when compared to school buses powered by conventional fuels.

William Schofield, superintendent of Hall County schools, says, “We choose propane autogas because not only does it represent significant reduced fuel costs and clean-burning properties, but also because the source, natural gas, is in abundant supply right here in America. With today’s tight school budgets, using a transportation fuel that saves taxpayers money, keeps the environment clean, and keeps jobs within our national borders is a win-win for everyone. Plus, our drivers love how quiet the propane buses perform.” Yancey Bros. Co. has been the Blue Bird® Bus Dealer in Georgia since 2007, and the business has grown quickly. “We’ve built relationships across the state,” says Jay McDuffie, Yancey sales manager. “We’re able to provide a level of service that people quickly come to appreciate and trust.”

New standards are also leading counties across Georgia to move toward lower-emissions equipment. In 2011 Bacon County, in south Georgia, took delivery of the first Tier 4 Caterpillar machine delivered in Georgia, a 140M2 motor grader. Tier 4 Interim is the current phase of emissions standards for off-highway diesel engines required by the federal government.

Bacon County’s 140M2 motor grader, featuring the Cat® C9.3 engine, meets U.S. EPA Tier 4 Interim emissions regulations using a combination of electronic, fuel, air, and after-treatment components.

Charlie Medders, Bacon County road superintendent, says, “We are excited to be the first owners of a Tier 4 Cat® machine in Georgia. We love the way the machine operates and are proud to bring a more environmentally friendly machine onto our roads.”
