The comment period was to end on January 30, 2012 (60 days after publication of the proposals in the                         **Federal Register**                        ). This document extends the comment period to February 13, 2012. This extension of the comment period is provided to allow the public additional time to comment on the proposed rule.

# SUPPLEMENTARY INFORMATION:

                    In the NHTSA and EPA proposals for “2017 and Later Model Year Light-Duty Vehicle Greenhouse Gas Emissions and Corporate Average Fuel Economy Standards,” the agencies invited comment from interested parties on all aspects of the proposal. EPA and NHTSA received multiple requests for a 30-day extension of the comment period. Those requests can be found in the dockets for the rulemaking listed above under                     **ADDRESSES**                    . The agencies have considered these requests and believe that a 14-day extension beyond the original 60 days would be sufficient. The agencies note that the proposal was prominently posted and available for public review on each agency's Web site on November 16, 2011. Thus, with a 14-day extension, commenters will have had, as a practical matter, a total of 90 days to review the rulemaking documents. Accordingly, the public comment period for the proposed rules is extended until February 13, 2012. Please see the agencies' discussion regarding consideration of comments received in the Notice of Proposed Rulemaking published in the                     **Federal Register**                     on December 1, 2011 (76 FR 75855-74856) and which is available on NHTSA's Web site at                     *http://www.nhtsa.gov/​staticfiles/​rulemaking/​pdf/​cafe/​2017-25_​CAFE_​NPRM.pdf*                     and EPA's Web site at                     *http://www.epa.gov/​otaq/​climate/​regulations.htm.*                     NHTSA and EPA will consider all comments received before the close of business on the comment closing date, and will also consider comments received after that date to the extent practicable.                

                    This extension of the comment period does not apply to NHTSA's Draft Environmental Impact Statement (Draft EIS), available on NHTSA's Web site at                     *www.nhtsa.gov/​fuel-economy.*                     The comment period for NHTSA's Draft EIS closes on January 31, 2012.                

The joint proposed rules issued by EPA and NHTSA would reduce greenhouse gas emissions and fuel consumption of light-duty vehicles for model years 2017-2025. 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 reduce greenhouse gas emissions and fuel consumption of light-duty vehicles for model years 2017-2025, building upon the success of the agencies' joint rulemaking to establish fuel economy and greenhouse gas emissions standards for model years 2012-2016. The proposal, consistent with the President's request, responds to the country's critical needs to address global climate change and to reduce oil consumption. NHTSA is proposing Corporate Average Fuel Economy standards under the Energy Policy and Conservation Act, as amended by the Energy Independence and Security Act, and EPA is proposing greenhouse gas emissions standards under the Clean Air Act. These standards would apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles, and, if ultimately adopted, would represent a continuation of the harmonized and consistent National Program. EPA is also proposing minor changes to the light-duty vehicle regulations applicable to model years 2012-2016, with respect to air conditioner performance, regulatory treatment of emergency vehicles, and measurement of nitrous oxides.

                    The proposal for which EPA and NHTSA are extending the comment period was published in the                     **Federal Register**                     on December 1, 2011 (76 FR 74854) and is also available at the Web pages listed above under                     **FOR FURTHER INFORMATION CONTACT**                     and in the rulemaking dockets.
