B. Public Participation 
EPA and NHTSA request comment on 
the information identified in this Notice. We are not requesting comment on other aspects of this joint proposed rule. This section describes how you can participate in this process. 
(1) How do I prepare and submit 
comments? 
There are many issues common to 
EPA’s and NHTSA’s proposals. For the convenience of all parties, comments submitted to the EPA docket will be considered comments submitted to the NHTSA docket, and vice versa. Therefore, a commenter only needs to submit comments to either of the agency dockets (or choose to submit a comment to both). Comments that are submitted for consideration by one agency should be identified as such, and comments that are submitted for consideration by both agencies should be identified as such. Absent such identification, each agency will exercise its best judgment to determine whether a comment is submitted on its proposal. 
(2) Tips for Preparing Your Comments 
When submitting comments, please 
remember to: 
•Identify the rulemaking by docket 
number and other identifying 
information (subject heading, Federal Register date and page number) 
•Explain why you agree or disagree, 
suggest alternatives, and substitute language for your requested changes 
•Describe any assumptions and 
provide any technical information and/or data that you used 
•If you estimate potential costs or 
burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced 
•Provide specific examples to illustrate 
your concerns, and suggest alternatives 
•Explain your views as clearly as 
possible, avoiding the use of profanity or personal threats •Make sure to submit your comments 
by the comment period deadline 
identified in the 
DATES section above 
(3) How can I be sure that my comments were received? 
NHTSA: If you submit your comments 
by mail and wish Docket Management to notify you upon its receipt of your comments, enclose a self-addressed, stamped postcard in the envelope containing your comments. Upon receiving your comments, Docket Management will return the postcard by mail. 
(4) How do I submit confidential 
business information? 
Any confidential business 
information (CBI) submitted to one of the agencies will also be available to the other agency. However, as with all public comments, any CBI information only needs to be submitted to either one of the agencies’ dockets and it will be available to the other. Following are 
specific instructions for submitting CBI to either agency. If you have any questions about CBI or the procedures for claiming CBI, please consult the persons identified in the 
FOR FURTHER  
INFORMATION CONTACT section. 
EPA: Do not submit CBI to EPA 
through www.regulations.gov or email. 
Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD ROM that you mail to EPA, mark the outside of the disk or CD ROM as CBI and then identify electronically within the disk or CD ROM the specific information that is claimed as CBI. Information not marked as CBI will be included in the public docket without prior notice. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. 
NHTSA: If you wish to submit any 
information under a claim of confidentiality, you should submit three copies of your complete submission, including the information you claim to be confidential business information, to the Chief Counsel, NHTSA, at the address given above under 
FOR FURTHER  
INFORMATION CONTACT . When you send a 
comment containing confidential business information, you should include a cover letter setting forth the information specified in our confidential business information 
regulation.

In addition, you should submit a copy 
from which you have deleted the claimed confidential business information to the Docket by one of the methods set forth above. 
(5) How can I read the comments 
submitted by other people? 
You may read the materials placed in 
the docket for this document (e.g., the 
comments submitted in response to this document by other interested persons) at any time by going to http://www.regulations.gov. Follow the online 
instructions for accessing the dockets. You may also read the materials at the EPA Docket Center or NHTSA Docket Management Facility by going to the street addresses given above under 
ADDRESSES . 
C. Background 
As part of the Climate Action Plan 
announced in June 2013,4the President 
directed the EPA and NHTSA to set the next round of standards to reduce greenhouse gas (GHG) emissions and improve fuel efficiency for medium- and heavy-duty vehicles and engines. More than 70 percent of the oil used in the United States and 28 percent of GHG emissions come from the transportation sector, and since 2009 EPA and NHTSA have worked with industry and the State of California to develop ambitious, flexible standards for both the fuel economy and GHG emissions of light- duty vehicles and the fuel efficiency and GHG emissions of heavy-duty vehicles and engines.
56Throughout 
every stage of development for these programs, EPA and NHTSA (collectively, the agencies, or ‘‘we’’) have worked in close partnership not only with each other, but with the vehicle and engine manufacturing industries, environmental community leaders, and the State of California, among other entities, to create a single, effective set of national standards. 
The agencies’ proposed Phase 2 
standards (80 FR 40138, July 13, 2015) would phase in through model year

2027, and were intended to result in an 
ambitious, yet achievable program that would allow manufacturers to meet standards through a mix of different technologies at reasonable cost. The proposed Phase 2 program would build on and advance the model years 2014– 2018 Phase 1 program in a number of important ways including: Basing standards not only on currently available technologies but also on utilization of technologies now under development or not yet widely deployed while providing significant lead time to assure adequate time to develop, test, and phase in these controls; developing standards for trailers; further encouraging innovation and providing 
flexibility; including vehicles produced by small business manufacturers; incorporating enhanced test procedures that (among other things) allow individual drivetrain and powertrain performance to be reflected in the vehicle certification process; and using an expanded and improved compliance simulation model. 
This notice alerts the public to new 
information placed in the agencies’ public dockets, and solicits comment on that information. The information takes the form of raw data, revised test reports, and memoranda that in some instances indicate potential implications of the data for purposes of standard stringency and 
implementation. In addition to information placed into the docket by the agencies, EPA also solicits 
comments on issues discussed in a late public comment that addresses proposed regulations related to light- duty motor vehicles used for racing. The agencies will accept comments on these materials through April 1, 2016. The agencies will not address new comments extraneous to these materials in the final rulemaking or its associated documents.
