49 CFR Part 536

2017 and Later Model Year Light-Duty Vehicle Greenhouse Gas 
Emissions and Corporate Average Fuel Economy Standards

AGENCY:  National Highway Traffic Safety Administration (NHTSA), 
Department of Transportation (DOT).

ACTION: Correcting amendment.

-----------------------------------------------------------------------

SUMMARY:  This document contains corrections to the final rule 
regulation which was published in the Federal Register of Monday, 
October 15, 2012 (77 FR 62624). The final rule established fuel economy 
standards for light-duty vehicles under the Energy Policy and 
Conservation Act (EPCA), as amended by the Energy Independence and 
Security Act (EISA), 49 U.S.C. 32901 et seq.

DATES: Effective Date: This correcting amendment is effective on 
December 14, 2012.

FOR FURTHER INFORMATION CONTACT:  Rebecca Yoon, Office of Chief 
Counsel, National Highway Traffic Safety Administration, 1200 New 
Jersey Avenue SE., Washington, DC 20590. Telephone: (202) 366-2992.

SUPPLEMENTARY INFORMATION: 

Background

    NHTSA and EPA published in the Federal Register of October 15, 
2012, final rules to establish coordinated standards to improve fuel 
economy and reduce greenhouse gas emissions for vehicles manufactured 
for sale in the United States in model years 2017 and beyond. The final 
rules, consistent with President Obama's directive to the agencies on 
May 21, 2010, respond to the country's critical need to reduce oil 
consumption and address global climate change.

Need for Correction

    As published, the final regulations inadvertently misprinted one of 
the values for ``VMTu,'' which represents lifetime vehicle 
miles traveled for the model year and compliance category in which a 
traded or transferred credit is used for compliance in 49 CFR part 536. 
The value printed for passenger cars in model year 2011 was 
``152,922,'' when the value intended to be printed, consistent with 
prior rulemakings, is ``150,922.'' To correct the mistake, NHTSA is 
replacing the value in the table to alleviate any confusion.

List of Subjects in 49 CFR Part 536

    Fuel economy, Reporting and recordkeeping requirements.

    Accordingly, 49 CFR part 536 is corrected by making the following 
correcting amendments:

PART 536--TRANSFER AND TRADING OF FUEL ECONOMY CREDITS

0
1. The authority citation for part 536 continues to read as follows:

    Authority:  49 U.S.C. 32903, delegation of authority at 49 CFR 
1.50.

0
2. Revise Sec.  536.4(c) to read as follows:


Sec.  536.4  Credits.

* * * * *
    (c) Adjustment factor. When traded or transferred and used, fuel 
economy credits are adjusted to ensure fuel oil savings is preserved. 
For traded credits, the user (or buyer) must multiply the calculated 
adjustment factor by the number of its shortfall credits it plans to 
offset in order to determine the number of equivalent credits to 
acquire from the earner (or seller). For transferred credits, the user 
of credits must multiply the calculated adjustment factor by the number 
of its shortfall credits it plans to offset in order to determine the 
number of equivalent credits to transfer from the compliance category 
holding the available credits. The adjustment factor is calculated 
according to the following formula:

Where:

A = Adjustment factor applied to traded and transferred credits.
VMTe = Lifetime vehicle miles traveled as provided in the 
following table for the model year and compliance category in which 
the credit was earned;
VMTu = Lifetime vehicle miles traveled as provided in the 
following table for the model year and compliance category in which 
the credit is used for compliance;

MPGse = Required fuel economy standard for the 
originating (earning) manufacturer, compliance category, and model 
year in which the credit was earned;
MPGae = Actual fuel economy for the originating 
manufacturer, compliance category, and model year in which the 
credit was earned;
MPGsu = Required fuel economy standard for the user 
(buying) manufacturer, compliance category, and model year in which 
the credit is used for compliance; and
MPGau = Actual fuel economy for the user manufacturer, 
compliance category, and model year in which the credit is used for 
compliance.
