Navistar last month delivered to the Columbus (Miss.) Municipal School District the first school buses certified by the U.S. Environmental Protection Agency as compliant with 2010 diesel emissions requirements. The school district purchased the 28 IC Bus CE Series buses with funding received earlier in the year from EPA in conjunction with the American Reinvestment and Recovery Act’s National Clean Diesel Funding Assistance Program.


The buses were built with EPA-certified MaxxForce DT Advanced Exhaust Gas Recirculation (EGR) engines. Navistar argues that its system is the only one that is not reliant on high operating temperatures needed to control oxides of nitrogen (NOx) emissions with other solutions. That’s important given the stop-and-go short-haul nature of school buses, Navistar says.
