Emissions Standards For Heavy-Duty Clean-Fuel Fleets Regulatory Support Document, Draft.
This document is intended to provide technical, environmental, and economic analyses of the heavy-duty portion of the Clean-Fuel Fleet program. The heavy-duty portion of the fleet program applies to only light heavy-duty and medium-heavy-duty vehicles and the engines designated for use in these vehicles. EPA is proposing to set a heavy-duty clean-fuel fleet vehicle standard of 3.5 g/Bhp-hr non-methane hydrocarbon (NMHC) and oxides of nitrogen (NOx). Credit generating standards for the fleet program are also being proposed. Technological discussions of NMHC and NOx formation and control, calculations of environmental benefits and an assessment of costs and cost effectiveness are also discussed.
