View Rule

As part of the 2012 rulemaking establishing the model year (MY) 2017-2025 light-duty vehicle GHG standards (77 FR 62624, October 15, 2012), EPA made a regulatory commitment to conduct a Mid-term Evaluation (MTE) of the MY 2022-2025 standards, in coordination with the Department of Transportation's National Highway Traffic Safety Administration (NHTSA) and the California Air Resources Board (CARB). The purpose of the MTE process is for EPA to decide whether the standards for MY 2022-2025 are still appropriate given the latest available data and information. EPA's regulations require several steps in the MTE process, including several opportunities for public input. The first step in the process was the joint issuance by EPA, NHTSA, and CARB of a Draft Technical Assessment Report (TAR) for public comment in July 2016, which examined a wide range of factors relevant to the MY 2022-2025 standards. Public input on the Draft TAR informed a subsequent Proposed Determination, which EPA issued for public comment in November 2016. A Final Determination was issued in January 2017, in which EPA responded to the public comments on the Proposed Determination and determined that the MY 2022-2025 standards should remain in place without change. In March 2017, EPA and the Department of Transportation (DOT) issued a Federal Register Notice (82 FR 14671, March 22, 2017) announcing Administrator Pruitt's intention to reconsider the Final Determination by April 1, 2018, and to coordinate the reconsideration with DOT. Throughout the MTE process, EPA will continue to examine a wide range of factors, such as developments in powertrain technology, vehicle electrification, light-weighting and vehicle safety impacts, the penetration of fuel efficient technologies in the marketplace, consumer acceptance of fuel efficient technologies, trends in fuel prices and the vehicle fleet, employment impacts, and many others.
