ENVIRONMENTAL PROTECTION AGENCY

[9919-45-OAR]

Technical Research Workshop Supporting EPA and NHTSA Phase 2 
Standards for MD/HD Greenhouse Gas and Fuel Efficiency

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of public workshop.

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

SUMMARY: EPA and NHTSA are sponsoring a technical workshop on December 
10 and 11, 2014, at Southwest Research Institute (SwRI) in San Antonio, 
Texas. SwRI researchers will present technical work completed under the 
direction of EPA and NHTSA to assist in developing Phase 2 medium- and 
heavy-duty GHG and fuel efficiency standards.

DATES: The workshop will be held at Southwest Research Institute 
December 10 and 11, 2014.

ADDRESSES: The workshop will be held at Southwest Research Institute, 
6220 Culebra Road, San Antonio, Texas 78238, 210-684-5111. A 
complimentary shuttle will be provided to and from Courtyard by 
Marriott San Antonio SeaWorld/Westover Hills, 11605 State Hwy 151, San 
Antonio, TX 78251, (210) 509-3700.

Transportation and Air Quality, U.S. Environmental Protection Agency,

SUPPLEMENTARY INFORMATION: EPA and NHTSA are sponsoring a technical 
workshop on December 10 and 11, 2014, at Southwest Research Institute 
(SwRI) in San Antonio, Texas. SwRI researchers will present technical 
work completed under the direction of EPA and NHTSA to assist in 
developing Phase 2 medium- and heavy-duty GHG and fuel efficiency 
standards.
    This technical work includes testing conducted over-the-road and on 
heavy-duty chassis dynamometers, powertrain test cells, and engine test 
cells. This work has been conducted to advance test procedure 
development and validate refinements that agencies have been 
considering for the greenhouse gas emissions model (GEM) used for 
heavy-duty vehicle certification. Aerodynamic tractor testing via both 
coast-down and constant-speed test procedures will also be presented, 
in addition to results from recent heavy-duty engine and vehicle 
technology modeling. SwRI will also describe simulation studies to look 
at the potential fuel saving performance of numerous MD/HD engine and 
vehicle technologies.
    This workshop will not include discussion of policy considerations 
such as Phase 2 program stringency or program structure. Rather, this 
workshop is an opportunity for interested stakeholders and individuals 
to learn more about recent EPA and NHTSA sponsored technical research, 
to engage directly with the SwRI researchers who have been conducting 
this work, and to provide initial feedback on work conducted to date.
    All interested parties are welcome to attend. See http://epa.gov/otaq/climate/regs-heavy-duty.htm for the agenda, schedule, and 
information regarding online registration. There is no registration 
fee.
