Title: Commercial Medium- and Heavy-Duty On-Highway Vehicles and Work Truck Fuel Efficiency Standards
Abstract: This rulemaking would respond to requirements of the Energy Policy and Conservation Act, as amended by the Energy Independence and Security Act of 2007. The statute requires that rulemaking begin with a report by the National Academy of Sciences evaluating medium-duty and heavy-duty truck fuel economy standards. The National Academy provided Congress and NHTSA with this report on March 18, 2010. EISA then requires that NHTSA complete a study that examines the fuel efficiency of commercial medium- and heavy-duty on-highway vehicles and work trucks and determines the appropriate test procedures and methodologies for measuring the fuel efficiency of such vehicles, the appropriate metric for measuring the fuel efficiency of such vehicles, the range of factors that affect the fuel efficiency of these vehicles, and other factors that could impact a program to improve the fuel efficiency of these vehicles. The NHTSA study was issued October 25, 2010. Once that study is completed, NHTSA has 24 months to complete a final rule establishing a fuel efficiency program for these vehicles. The law provides that the new standards must provide at least 4 full model years of regulatory leadtime and 3 full model years of regulatory stability (i.e., the standards must remain in effect for 3 years before they may be amended). On May 21, 2010, President Obama issued a memorandum directing NHTSA and EPA conduct a joint rulemaking (NHTSA regulating fuel efficiency and EPA regulating greenhouse gas emissions), and to issue a final rule by July 30, 2011.
