JUSTIFICATION FOR CHANGE

Motor Vehicle Emission and Fuel Economy Compliance: Light Duty Vehicles, Light Duty Trucks, and Highway Motorcycles; OMB Number 2060-0026

At the request of OMB, this submisson breaks out ICR 0783.47, the last renewal of the certification ICR, into five ICs: Light Duty Truck and Light Duty Vehicle Emissions, Fuel Economy, Manufacturers' In-Use Vehicle Program, Highway Motorcycles, and Defect Reports and Voluntary Emission Recall Reports. The aggregate hours and costs of these five ICs together equal the hour and costs authorized in 0783.47 and do not reflect any program changes since that renewal. The Fuel Economy IC will be the baseline for the final rule Fuel Economy Labeling ICR, 0783.51. This submission also adjusts response numbers to count them in the units of emission families or test groups, and causes a change in the aggregate number or respondents only because of the disaggregation.
