The California Air Resources Board (CARB) is circulating draft regulations that would require sleeper-cab tractors and 53-foot box-type trailers operating on any highway in California be United States Environmental Protection Agency (EPA) SmartWay-certified vehicles.
Regulations would apply to 2011-model and later equipment, and would make brokers, shippers, and receivers responsible for ensuring that the regulations are followed.
Among basic specifications for an EPA-certified SmartWay tractor: integrated cab-high roof fairing; tractor-mounted side fairing gap reducers; tractor fuel-tank side fairings; aerodynamic bumper and mirrors; options for reducing periods of extended engine idling (auxiliary power units, generator sets, direct-fired heaters, battery-powered HVAC system, and automatic engine start/stop system); and options for low-rolling resistance tires (single wide or dual) mounted on aluminum wheels.
Basic specs necessary to qualify as an EPA-certified SmartWay trailer: side skirts; weight-saving technologies; gap reducer on the front or trailer tails (either extenders or boat tails); and options for low-rolling resistance tires (single wide or dual) mounted on aluminum wheels.
The SmartWay Transport Partnership is a collaboration between the U.S. EPA and the freight industry to increase energy efficiency while reducing greenhouse gases and air pollution.
