2017 and Later Model Year Light-Duty Vehicle GHG Emissions and CAFE Standards: Supplemental Notice of Intent
On May 21, 2010, President Obama issued a Presidential Memorandum requesting that the Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA), on behalf of the Department of Transportation, develop, through notice and comment rulemaking, a coordinated National Program under the Clean Air Act (CAA) and the Energy Policy and Conservation Act (EPCA), as amended by the Energy Independence and Security Act (EISA), to improve fuel economy and to reduce greenhouse gas emissions of light-duty vehicles for model years 2017-2025. President Obama requested that the agencies issue a Notice of Intent (NOI) to issue a proposed rulemaking that announces plans for setting stringent fuel economy and greenhouse gas emissions standards for light-duty vehicles for model year 2017 and beyond. On September 30, 2010, the agencies issued the requested Notice, which described the agencies' initial assessment of potential levels of stringency for a National Program for model years 2017-2025 (See 75 FR 62739 (Oct. 13, 2010). This Supplemental Notice highlights input on many of the key issues the agencies have received in response to the September NOI and the accompanying Interim Joint Technical Assessment (TAR) developed by EPA, NHTSA, and the California Air Resources Board, and also provides an overview of many of the key technical analyses the agencies have planned and are conducting to support the upcoming proposed rule.
