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.

  2. 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.

  3. 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.5 6 Throughout 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

    Page 10825

    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.
