| Title: Fuel Economy Regulations for Automobiles: Technical Amendments and Corrections | |
| Abstract: This action amends and corrects portions of the Environmental Protection Agency's (EPA) existing fuel economy regulations, located at 40 CFR part 600. There are two reasons for this action. First, some minor corrections and amendments are needed to correct portions of EPA's final rule for fuel economy labeling requirements for cars and light trucks (71 FR 77872, Dec. 27, 2006). Some typographical errors and errors of omission will be corrected. Second, the Department of Transportation finalized new average fuel economy standards for light trucks on April 6, 2006 (71 FR 77872). This rule amended the existing DOT regulations at 49 CFR parts 523, 533, and 537, by adding new definitions, setting new fuel economy standards for light trucks, and amending some reporting requirements. In order for DOT to execute its new requirements, DOT's regulations rely on EPA to reference the new definitions and collect the new information from automobile manufacturers, so that EPA can determine the new light truck average fuel economy targets. The new definitions include "medium duty passenger vehicle" and "footprint". Under the Energy Policy and Conservation Act (EPCA), EPA is required to calculate the average fuel economy of a manufacturer using methods it prescribes by regulation. (49 U.S.C. 32904(a)(1)(A)). EPA has conducted this activity for about 30 years and this rulemaking only updates the information the Agency will receive from the auto manufacturers. The changes adopted by DOT include a new requirement to determine the "footprint" for each model type of vehicle, so that target standards can be calculated. EPA must therefore collect "footprint" data from auto manufacturers, which includes measurements for front track width, rear track width, wheelbase and final sales of each model type. EPA's current regulations do not require manufacturers to submit this information, thus a minor amendment is needed to add this information collection. The DOT rule takes effect with 2008 model year trucks, which can begin to be produced as early as January 2, 2007, thus it is important that EPA begin collecting this new information as soon as possible. These changes do not change the existing EPA test procedures or calculation methods for average fuel economy. | |
