49 CFR 531.6 - Measurement and calculation procedures.
(a) The fleet average fuel economy performance of all passenger automobiles that are manufactured by a manufacturer in a model year shall be determined in accordance with procedures established by the Administrator of the Environmental Protection Agency under 49 U.S.C. 32904 and set forth in 40 CFR part 600. For model years 2017 to 2025, a manufacturer is eligible to increase the fuel economy performance of passenger cars in accordance with procedures established by EPA set forth in 40 CFR part 600, including any adjustments to fuel economy EPA allows, such as for fuel consumption improvements related to air conditioning efficiency and off-cycle technologies.
(b) The eligibility of a manufacturer to increase its fuel economy performance through use of an off-cycle technology requires an application request made to EPA in accordance with 40 CFR Part 86.1869-12 and an approval granted by EPA made in consultation with NHTSA. In order to expedite NHTSA's consultation with EPA, a manufacturer's application as part of the off-cycle credit approval process under 40 CFR 86.1869-12(b) or 40 CFR 86.1869-12(c) shall also be submitted to NHTSA at the same time if the manufacturer is seeking off-cycle fuel economy improvement values under the CAFE program for those technologies. For off-cycle technologies which are covered under 40 CFR 86.1869-12(b) or 40 CFR 86.1869-12(c), NHTSA will consult with EPA regarding NHTSA's evaluation of the specific off-cycle technology to ensure its impact on fuel economy and the suitability of using the off-cycle technology to adjust the fuel economy performance. NHTSA will provide its views on the suitability of the technology for that purpose to EPA. NHTSA's evaluation and review will consider:
(1) Whether the technology has a direct impact upon improving fuel economy performance;
(2) Whether the technology is related to crash-avoidance technologies, safety critical systems or systems affecting safety-critical functions, or technologies designed for the purpose of reducing the frequency of vehicle crashes;
(3) Information from any assessments conducted by EPA related to the application, the technology and/or related technologies; and
(4) Any other relevant factors.

Comments must be received on or before October 5, 2017. EPA will announce the public hearing date and location for this document in a supplemental Federal Register publication. 49 CFR Parts 523, 531, 533, 536 and 537 In a March 22, 2017, Federal Register document, the Environmental Protection Agency (EPA) announced its intention to reconsider the Final Determination of the Mid-term Evaluation of greenhouse gas emissions standards for model year 2022-2025 light-duty vehicles and to coordinate its reconsideration with the parallel rulemaking process to be undertaken by the Department of Transportation's National Highway Traffic Safety Administration (NHTSA) regarding Corporate Average Fuel Economy (CAFE) standards for cars and light trucks for the same model years. In this document, EPA is announcing that it is reconsidering whether the light-duty vehicle greenhouse gas standards previously established for model years 2022-2025 are appropriate under section 202(a) of the Clean Air Act and invites stakeholders to submit any comments, data, and information they believe are relevant to the Administrator's reconsideration of the January 2017 Mid-term Evaluation Final Determination and in particular, highlight any new information. As part of a 2012 joint final rulemaking by the EPA and NHTSA, the Mid-term Evaluation process was codified in EPA regulation for greenhouse gas emission standards for model years 2017-2025 light-duty vehicles, which requires EPA to determine no later than April 1, 2018, whether the standards for model years 2022-2025 are appropriate. 1 In accord with this schedule, as noted in the March 22, 2017, document and this document, EPA intends to make a Final Determination regarding the appropriateness of the model year 2022-2025 standards no later than April 1, 2018. In this document, EPA is also requesting comment on the separate question of whether the light-duty vehicle greenhouse gas standards established for model year 2021 remain appropriate, regardless of the agency's decision on the MTE. 1 40 CFR 86.1818-12(h); see also 77 FR 62624 (October 15, 2012).

This final rule is effective on December 14, 2012, sixty days after date of publication in the Federal Register . The incorporation by reference of certain publications listed in this regulation is approved by the Director of the Federal Register as of December 14, 2012. 40 CFR Parts 85, 86, and 600 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.
