Greenhouse Gas Emissions and Fuel Efficiency Standards for 
Medium- and Heavy-Duty Engines and Vehicles--Phase 2--Notice of Data 
Availability

AGENCIES: Environmental Protection Agency (EPA) and Department of 
Transportation (DOT) National Highway Traffic Safety Administration 
(NHTSA).

ACTION: Notice of data availability.

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

SUMMARY: This Notice provides an opportunity to comment on new 
information being made available by the EPA and by NHTSA, on behalf of 
DOT, related to the proposed Phase 2 Heavy-Duty National Program 
proposed July 13, 2015, to reduce greenhouse gas emissions and fuel 
consumption for new on-road heavy-duty vehicles and engines. The new 
information, including memoranda and data, have been placed in the 
public dockets. Data relating to the potential stringency of the 
proposed standards includes: Powertrain data; additional aerodynamic 
test data; supplemental test data relating to drive cycles (and 
frequency thereof) for vocational vehicles; and cycle average mapping 
data. The agencies are soliciting additional comment on certain revised 
test reports, and a revised version of the Greenhouse Gas Emission 
Model (GEM) used both in developing certain of the proposed standards 
and in demonstrating compliance with those standards. Additionally, EPA 
is soliciting further comment on memoranda relating to standard 
applicability and implementation. These memoranda address potential 
requirements for selective enforcement audits and confirmatory testing 
related to greenhouse gas emissions, and applicability of emission 
standards and certification responsibilities for trailers, glider 
vehicles, and glider kits. Finally, EPA is soliciting additional 
comments on issues discussed in a late comment related to light-duty 
motor vehicles used for racing.

DATES: Comments must be received on or before April 1, 2016.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-HQ-

encourage you to write your primary comments in a concise fashion. 
However, you may attach necessary additional documents to your 
comments, and there is no limit on the length of the attachments. If 
you are submitting comments electronically as a PDF (Adobe) file, we 
ask that the documents submitted be scanned using the Optical Character 
Recognition (OCR) process, thus allowing the agencies to search and 
copy certain portions of your submissions.\2\ Please note that pursuant 
to the Data Quality Act, in order for the substantive data to be relied 
upon and used by the agency, it must meet the information quality 
standards set forth in the OMB and Department of Transportation (DOT) 
Data Quality Act guidelines. Accordingly, we encourage you to consult 
the guidelines in preparing your comments. OMB's guidelines may be

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.\3\
---------------------------------------------------------------------------

    \3\ See 49 CFR part 512.
---------------------------------------------------------------------------

    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,\4\ the 
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.
