AGENCY : National Highway Traffic

ACTION : Notice of proposed rulemaking; 
correction. 
SUMMARY : This document corrects 
technical errors in the proposed rule that appeared in the Federal Register on August 17, 2023, entitled ‘‘Corporate Average Fuel Economy Standards for Passenger Cars and Light Trucks for Model Years 2027–2032 and Fuel Efficiency Standards for Heavy-Duty Pickup Trucks and Vans for Model Years 2030–2035.’’ That document proposed new Corporate Average Fuel Economy (CAFE) standards for passenger cars and light trucks to be manufactured in model years (MYs) 2027–2032, and new fuel efficiency standards for heavy-duty pickup trucks and vans (HDPUVs) to be manufactured in MYs 2030–2035. 
DATES : Comments for the proposed rule 
published on August 17, 2023, at 88 FR 56128, must be received on or before October 16, 2023.

SUPPLEMENTARY INFORMATION : Prior to 
publication of the proposal for new CAFE standards for passenger cars and light trucks and new fuel efficiency standards for HDPUVs, NHTSA noticed several minor typographical errors that could not be corrected prior to printing. The needed corrections to the preamble replace the target function coefficient numbers in Table II–3, Table III–4, Table III–12, Table III–13, Table III–15, Table III–16, Table III–18, Table III–19, Table III–21, and Table III–22. NHTSA notes that these modifications do not change the values but simply provide additional significant figures for the coefficients. For the reader’s reference, NHTSA has also made the corresponding changes to the target coefficient tables in the accompanying Technical Support Document (TSD) and Preliminary Regulatory Impact Assessment (PRIA), which are found in the docket for this rulemaking and on the agency’s website. The needed correction to the proposed regulatory text clarifies that NHTSA is proposing to eliminate 5-cycle and alternative approvals for off-cycle fuel consumption incentive values (FCIVs) starting in MY 2027. This document also corrects the proposed regulatory text to clarify that multipliers for advanced, innovative, and off-cycle technologies for heavy- duty pickup trucks and vans are available through model year 2027.

Public Hearing for Corporate Average 
Fuel Economy Standards for Passenger Cars and Light Trucks for Model Years 2027–2032 and Fuel Efficiency Standards for Heavy-Duty Pickup Trucks and Vans for Model Years 2030–2035 
AGENCY : National Highway Traffic 
Safety Administration (NHTSA), Department of Transportation (DOT). 
ACTION : Notice of public hearing. 
SUMMARY : The National Highway Traffic 
Safety Administration (NHTSA) is announcing a virtual public hearing to be held September 28, 2023, on its proposal for the ‘‘Corporate Average Fuel Economy Standards for Passenger Cars and Light Trucks for Model Years 2027–2032 and Fuel Efficiency Standards for Heavy-Duty Pickup Trucks and Vans for Model Years 2030– 2035,’’ which was signed on July 28, 2023. This hearing also allows the public to provide oral comments regarding the Draft Environmental Impact Statement that accompanies the proposal. An additional session will be held on September 29, if necessary, to accommodate the number of people that sign up to testify. 
DATES : NHTSA will hold a virtual 
public hearing on September 28, 2023. An additional session will be held on September 29, if necessary, to accommodate the number of people that sign up to testify. The hearing will convene at 9 a.m. Eastern time and will conclude when the last pre-registered speaker has testified but no later than 6 p.m. Eastern time. All hearing attendees, including those who do not intend to provide testimony, should preregister by September 22, 2023. Please refer to the 
SUPPLEMENTARY INFORMATION section for 
additional information on the public hearing. 
ADDRESSES : The link to register will be 
available at https://www.nhtsa.gov/cafe. 
Additional information regarding the hearing appears below under 
SUPPLEMENTARY INFORMATION . 
FOR FURTHER INFORMATION CONTACT : For 
questions regarding how to register to attend the hearing, please contact NHTSA’s Office of Communications at NHTSA.Communication@dot.gov . For any other questions about this notice, please contact Mark Totten, Office of Rulemaking, NHTSA, at (202)-209– 3170. 
SUPPLEMENTARY INFORMATION : NHTSA, 
on behalf of the DOT, is proposing new corporate average fuel economy (CAFE) standards for passenger cars and light trucks for MYs 2027–2032, and new fuel efficiency standards for heavy-duty pickup trucks and vans (HDPUVs) for MYs 2030–2035. This proposal responds to NHTSA’s statutory obligation to set CAFE and HDPUV standards at the maximum feasible level that the agency determines vehicle manufacturers can achieve in each MY, in order to improve energy conservation. Specifically, NHTSA is proposing new fuel economy standards for passenger cars and light trucks and fuel efficiency standards for model years (MYs) 2027–31 that increase at a rate of 2 percent per year for passenger cars and 4 percent per year for light trucks, and new fuel efficiency standards for heavy-duty pickup trucks and vans (HDPUVs) for MYs 2030–2035 that increase at a rate of 10 percent per year. NHTSA is also setting forth proposed augural standards for MY 2032 passenger cars and light trucks, which would increase at 2 percent and 4 percent year over year, respectively, as compared to the prior year’s standards. In addition, NHTSA is also proposing certain technical amendments to clarify and streamline our compliance regulations. The proposal was signed on July 28, 2023, and was published in the Federal Register on August 17, 2023. A notice of availability for the accompanying Draft Environmental Impact Statement (Draft EIS) was published in the Federal Register on 
August 04, 2023 (88 FR 51812). The Draft EIS is available on NHTSA’s CAFE website, https://www.nhtsa.gov/cafe, 
and is also available in Docket ID No. NHTSA–2022–0075
