EGR vs SCR * USA - Navistar tries to block rivals' role in EPA lawsuit
Navistar doesn't want its competitors butting into its court challenge of the EPA's decision to allow a rival technology for 2010 engines
Washington,DC,USA -Today's Trucking (CAN) -12 June 2009: -- ... In yet another petition filed with the federal Court of Appeals, Navistar -- which, as it's well known by now, is the only major truck OEM not using selective catalytic reduction (SCR) technology in upcoming 2010 engines -- is attempting to block pro-SCR truck makers from getting a say in the lawsuit against the Environmental Protection Agency... Not holding back any punches, the company also used the opportunity to further attack the EPA and SCR as a viable technology... Last week Cummins, Detroit Diesel, Volvo and Mack responded to the original suit against EPA by collectively filing what's known in legal jargon as a Amici Curiae (AC) motion (literally translated to "friends of the court")... Navistar, not surprisingly, is asking the court to reject the AC. It predicts that its competitors will "not offer a unique and important perspective” and will only echo the briefings EPA already filed with the court. The company also brushed off SCR manufacturers' position that they have “expended significant resources" to develop the technology, since most of the truckmakers had been using similar SCR solutions in Europe... In particular, Navistar contends that by changing course, EPA improperly allowed SCR systems to incorporate a 'ramped shutdown' feature in case DEF tanks run dry. Navistar likens this allowance to a "licence to pollute" and "pollution for convenience."...
