In preparation for the heavy-duty vehicle and engine public
workshop including proposed modifications to the Tractor-Trailer
GHG regulation and the Airborne Toxic Control Measure (ATCM) to
Limit Diesel-Fueled Commercial Motor Vehicle Idling, on Monday,
March 11, 2013, the California Air Resources Board (ARB or Board)
has posted staff presentations on the program websites:.

At the workshop, staff will be soliciting input on the following
proposals: 

•	Adopting a new regulation to harmonize with the Greenhouse Gas
(GHG) Emissions Standards for Medium- and Heavy-Duty Engines and
Vehicles that U.S. EPA adopted in 2011;
•	Making amendments to ARB’s existing Heavy-Duty Vehicle GHG
Emission Reduction Regulation (Tractor-Trailer GHG regulation) to
align with the proposed new regulation above; 
•	Adopting a new set of optional oxides of nitrogen (NOx)
standards for heavy-duty vehicle engines more stringent than the
current 2010 model year standard;
•	Making amendments to ATCM to Limit Diesel-fueled Commercial
Motor Vehicle Idling to expand compliance responsibility; and
•	Making amendments to ARB’s existing labeling requirements to
create a new label category for zero emission heavy-duty
vehicles.

  
The workshop is described further in the workshop notice at

will be held at the following time and location: 

Date:		Monday, March 11, 2013

Background: 

In September 2011, U.S. EPA adopted a new regulation for
controlling GHG emissions from new medium and heavy-duty engines
and vehicles.  ARB staff is proposing to align with the federal
regulation in order to provide California with the ability to
certify engines and vehicles to the new standards as well as
enforce them.  

On December 11, 2008, the Board approved the Tractor-Trailer GHG
regulation codified in sections 95300-95312 of title 17, of the
California Code of Regulations (CCR), and later amended it on
December 17, 2010. This regulation reduces GHG emissions from
long-haul tractor-trailer combinations by requiring them to
utilize U.S. EPA SmartWay verified or designated technologies
that will improve fuel efficiency.  To harmonize the tractor
requirements of the federal and California regulations, ARB staff
is considering modifications to its Tractor-Trailer GHG
regulation. 

ARB staff will be proposing optional NOx emission standards for
California certified 2015 and later model year engines.  If the
optional standards are adopted, ARB’s existing incentive programs
such as the Carl Moyer Memorial Air Quality Standards Attainment
program could be modified to give preference to engines certified
to the optional standards. 

On July 22, 2004, ARB adopted an ATCM to Limit Diesel-fueled
Commercial Motor Vehicle Idling.  This regulation is codified in
title 13 CCR, section 2485, and was later amended on October 20,
2005 and December 11, 2008.  ARB staff is proposing to extend
responsibility for complying with the requirements of the idling
ATCM to the owner of the vehicle. In addition, staff’s proposal
would require California-based shippers and California-based
brokers to share responsibility for compliance with the idling
restrictions in the event that they utilized the services of
motor carriers that violated the regulation and/or they did not
settle their outstanding fines.  

For specific questions regarding the new heavy duty engine and
vehicle GHG regulation and the optional engine NOx standard, you
may contact Ms. Kim Heroy-Rogalski, Manager of the Off-Road
Implementation Section, by email at kheroyro@arb.ca.gov or by
phone at (916) 327 2200.  

For questions regarding the in-use tractor-trailer GHG regulation
amendments and the anti-idling ATCM amendments, you may contact
Mr. Stephan Lemieux, Manager of the On-Road Heavy Duty Diesel
Section, by email at slemieux@arb.ca.gov or by phone at (626)
450-6162.  

Thank you.
