* California - Air Quality Regulators target Nitrogen Oxide emissions reduction
-- State air quality regulators in California said proposed Phase 2 standards for reducing greenhouse-gas emissions and increasing fuel efficiency for medium- and heavy-duty trucks do not go far enough... At a public hearing Aug. 18 in Long Beach, they called for reducing the existing standard on nitrogen oxide emissions from medium- and heavy-duty trucks to near-zero levels as part of the pending proposal... Mary Nichols, chairwoman of the California Air Resources Board, said at the hearing, an earlier implementation date of the proposal “would allow for more timely options to pursue a mandatory lower nitrogen oxide engine standard nationally.” She said reducing NOx is “absolutely critical” if California is to meet its federal ozone attainment obligations. She said trucks are responsible for one-third of the state’s NOx emissions... Tom Fulks, representing the Diesel Technology Forum, based in Frederick, Maryland, said 120,429 model year 2010-2014 “clean diesel” Classes 3-8 trucks are operating in California. They have eliminated 120,000 tons of NOx and 580,000 tons of carbon dioxide and saved 1.4 billion barrels of crude oil between 2010 and 2014, he said, based on DTF’s most recent research. DTF is a nonprofit organization that raises awareness of the importance of diesel engines, fuel and technology...

* California - CARB calls for technology-forcing emissions limits, focus on NOx
-- The second public hearing on proposed truck fuel efficiency and greenhouse gas emissions standards shaped up much like the first: Trucking industry representatives expressed qualified support for the stringency goals and implementation schedule outlined by the Environmental Protection Agency (EPA), while air quality regulators and environmental groups called for tougher restrictions and a tighter timeline. And within trucking there is a divide over exactly how the engine and complete vehicle should be measured... The big four North American heavy-duty truck manufacturers (Daimler Trucks North America, Navistar, Paccar and Volvo Trucks North America) spoke with one voice Tuesday, as Dan Kieffer, director of emissions compliance for Paccar, delivered a statement on behalf of all... He also called on the agencies to adopt a “complete vehicle approach” to the regulation, as opposed to separate vehicle and engine standards... The truck manufacturers’ opposition to the engine standard goes against support from the world’s largest engine-builder, Cummins Inc. ... “The fact is that vehicle manufacturers must have the flexibility to optimize the complete vehicle design for maximum efficiency at the lowest cost and complexity. Minimizing total cost of vehicle ownership is a top priority for our customers.” says Dan Kieffer...
