“I’m conservative when I run numbers, and the savings were amazing. We’re saving a total of 32.6 cents per mile with propane autogas,” said Ron Latko, director of transportation and vehicle maintenance, Mesa Public Schools in Arizona.

“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 our propane autogas buses perform,” said William Schofield, superintendent, Hall County Schools in Georgia.

Traditional Yellow School Buses Go ‘Green’

Alt Fuel School BusWith approximately 53 percent of all children boarding the traditional yellow diesel-burning school buses twice a day for their daily mode of transportation, safety is the top priority for school bus operators across the nation.

ROUSH CleanTech’s propane autogas offerings fit perfectly with this commitment to safety. Propane autogas is safe, non-toxic, and non-poisonous. Because it is a gas at normal atmospheric temperature and pressure, propane autogas does not spill, pool, or leave residue. Propane autogas fuel tanks are 20 times more puncture resistant than typical gasoline or diesel tanks, and propane has the lowest flammability range (500 degrees) of any alternative fuel – even lower than conventional gasoline (850 degrees). See Safety.

One individual who took his district’s commitment to safety a step further is Ron Latko, director of transportation and vehicle maintenance at Mesa Public Schools in Phoenix, Ariz. His mission was to provide a cleaner environment for students without changing the level of safety. Latko found propane autogas to be their solution to reduce emissions and cut costs at the same time. With savings of 32.6 cents per mile, Mesa Public Schools is able to keep the focus and the funding on increasing the quality of education for the district’s students.
