Greenhouse Gas Emissions and Fuel Efficiency Standards for

Comment Period

AGENCY: Environmental Protection Agency (EPA) and National Highway 
Traffic Safety Administration (NHTSA), DOT.

ACTION: Proposed rule; extension of comment period.

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

SUMMARY: The Environmental Protection Agency (EPA) and the National 
Highway Traffic Safety Administration (NHTSA) are extending the comment 
period for the joint proposed rules ``Greenhouse Gas Emissions and Fuel 
Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles--
Phase 2,'' and also for NHTSA's Draft Environmental Impact Statement 
(DEIS). The proposed rules were published in the Federal Register on 
July 13, 2015. The comment period for the proposed rules was to end on 
September 17, 2015. The DEIS was published to a NHTSA Docket on June 
19, 2015, and the comment period for that document was to end on August 
31, 2015. The purpose of this action is to extend the comment period 
for the proposed rules and the DEIS to October 1, 2015.

DATES: The comment period for the proposed rule published July 13, 2015 
(80 FR 40139) is extended. Written comments for both documents must be 
received on or before October 1, 2015.

[[Page 53757]]

should be addressed to EPA: Tad Wysor, Office of Transportation and Air 
Quality, Assessment and Standards Division (ASD), Environmental 
Protection Agency, 2000 Traverwood Drive, Ann Arbor, MI 48105; 
telephone number: (734) 214-4332; fax number: (734) 214-4050; email 
address: wysor.tad(at)epa.gov. You may learn more about the jointly 
proposed rules by visiting NHTSA's or EPA's Web sites at http://www.nhtsa.gov/fuel-economy or http://www.epa.gov/otaq/climate/regs-heavy-duty.htm or by searching the rulemaking dockets (NHTSA-2014-0132; 
EPA-HQ-OAR-2014-0827) at www.regulations.gov.

SUPPLEMENTARY INFORMATION: In response to requests for an extension, we 
are extending the public comment period for the Heavy-Duty Phase 2 
Notice of Proposed Rulemaking (80 FR 40139, July 13, 2015; also 
available in Docket Nos. EPA-HQ-OAR-2014-0827 and NHTSA-2014-0132) to 
October 1, 2015. As NHTSA published (to Docket No. NHTSA-2014-0074) an 
accompanying DEIS for NHTSA's proposed rule, we are also extending the 
comment period for that document to October 1, 2015. This extension 
will provide the public additional time to provide comment on the 
proposed rules and DEIS. Both the proposed rules and the DEIS are 
available at www.regulations.gov. Instructions for submitting comments 
to either EPA or NHTSA are described in the Public Participation 
section of the Notice of Proposed Rulemaking.
    In this joint proposal, there are many issues common to both 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. An exception is that comments 
submitted to the NHTSA docket on NHTSA's (DEIS) will not be considered 
submitted to the EPA docket. Therefore, the public only needs to submit 
comments to either one of the two agency dockets, although they may 
submit comments to both if they so choose. 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.

Administration.
