§ 32902 - Average fuel economy standards
Title 49 published on 09-May-2017 04:41
The following are ALL rules, proposed rules, and notices (chronologically) published in the Federal Register relating to 49 CFR Part 531 after this date.
EPA announces its intention to reconsider the Final Determination of the Mid-Term Evaluation of greenhouse gas (GHG) standards for model year (MY) 2022-2025 light-duty vehicles and to coordinate its reconsideration with the parallel process to be undertaken by the DOT's NHTSA regarding Corporate Average Fuel Economy (CAFE) standards for cars and light trucks for the same model years.
This notice partially grants a petition for rulemaking submitted by the Alliance of Automobile Manufacturers and the Association of Global Automakers (hereinafter collectively referred to as “Petitioners”) on June 20, 2016, to consider amending various aspects of the light vehicle Corporate Average Fuel Economy (CAFE) regulations. The Petitioners requested that NHTSA issue a direct final rule to implement the requested changes, but NHTSA believes that the issues and questions raised by the Petitioners are worthy of notice and comment. NHTSA will address the changes requested in the Petition in the course of the rulemaking proceeding, in accordance with statutory criteria.
EPA and NHTSA, on behalf of the Department of Transportation, are issuing final rules to further reduce greenhouse gas emissions and improve fuel economy for light-duty vehicles for model years 2017 and beyond. On May 21, 2010, President Obama issued a Presidential Memorandum requesting that NHTSA and EPA develop through notice and comment rulemaking a coordinated National Program to improve fuel economy and reduce greenhouse gas emissions of light-duty vehicles for model years 2017-2025, building on the success of the first phase of the National Program for these vehicles for model years 2012-2016. This final rule, consistent with the President's request, responds to the country's critical need to address global climate change and to reduce oil consumption. NHTSA is finalizing Corporate Average Fuel Economy standards for model years 2017-2021 and issuing augural standards for model years 2022-2025 under the Energy Policy and Conservation Act, as amended by the Energy Independence and Security Act. NHTSA will set final standards for model years 2022-2025 in a future rulemaking. EPA is finalizing greenhouse gas emissions standards for model years 2017-2025 under the Clean Air Act. These standards apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles, and represent the continuation of a harmonized and consistent National Program. Under the National Program automobile manufacturers will be able to continue building a single light-duty national fleet that satisfies all requirements under both programs while ensuring that consumers still have a full range of vehicle choices that are available today. EPA is also finalizing minor changes to the regulations applicable to model years 2012-2016, with respect to air conditioner performance, nitrous oxides measurement, off-cycle technology credits, and police and emergency vehicles.
EPA and NHTSA are announcing a 14-day extension of the comment period for the joint proposed rules “2017 and Later Model Year Light-Duty Vehicle Greenhouse Gas Emissions and Corporate Average Fuel Economy Standards,” published in the Federal Register on December 1, 2011 (76 FR 74854). The comment period was to end on January 30, 2012 (60 days after publication of the proposals in the Federal Register ). This document extends the comment period to February 13, 2012. This extension of the comment period is provided to allow the public additional time to comment on the proposed rule. The extension of the comment period does not apply to NHTSA's Draft Environmental Impact Statement (Draft EIS), available on NHTSA's Web site at www.nhtsa.gov/fuel-economy. The comment period for NHTSA's Draft EIS closes on January 31, 2012.
