For the Record
The company added that the 440-mile test run by Navistar is too short for testing modern EPA 2010-compliant trucks in a working environment.
Meanwhile, Volvo Group strongly defended the effectiveness of SCR and warned against revamping the regulations with the roll-out of EPA 2010-compliant engines already well under way. “We question the need to make modifications to SCR strategies just six months after SCR products were brought to market,” said Steve Berry, director of government relations with Volvo Powertrain.
Navistar is the only U.S. heavy-duty truck manufacturer to use only an EGR solution to meet stringent 2010 U.S. Environmental Protection Agency regulations limiting diesel pollutants. All other North American engine manufacturers have elected to use SCR technology, which sprays hot diesel exhaust gas with a urea-based diesel exhaust fluid.
ATA Sponsors Video Contest for Truck Driver Appreciation Week
The American Trucking Associations will sponsor a video contest for National Truck Driver Appreciation Week Sept. 19-25.
ATA is seeking amateur video submissions from professional truck drivers, driver’s families, shippers, suppliers, allied companies or community members explaining why professional truck drivers are essential. Entries can be produced with cell phone or home video cameras — with the emphasis on creativity and message, rather than production values.
The deadline for contest submissions is Sept. 13. Submissions should be posted to YouTube, tagged with “ATATrucksBringIt” and the URL e-mailed to email@example.com.
Alternately, entries can be sent to firstname.lastname@example.org or American Trucking Associations, ATA Image and Outreach, 950 N. Glebe Road, Suite 210, Arlington, VA 22203.

Agencies to Consider SCR ‘Loopholes’
By Jack Roberts
The U.S. Environmental Protection Agency and the California Air Resources Board have presented preliminary proposals aimed at the alleged compliance loopholes found in current 2010 liquid-based selective catalytic reduction systems on diesel engines.
SCR technology doses hot diesel fuel with a urea-based diesel exhaust fluid. The resulting chemical reaction reduces emissions of nitrous oxide (NOx) pollutants to levels mandated by EPA’s 2010 diesel emissions regulations.
Concerns about SCR’s environmental compliance were brought to the organizations’ attention by truck and engine manufacturer Navistar International, which uses a competitive technology, exhaust gas recirculation, to meet EPA 2010 regulations.
