arbcombo -- optionnox, phaselghg – Public workshop March 11, 2013, 8:30 am in Sacramento

Posted: 20 Feb 2013 09:40:37
The California Air Resources Board (ARB or Board) invites you to
participate in a public workshop on March 11, 2013, to discuss
proposals for several regulations and regulation amendments
related to on-road heavy-duty vehicles. At this 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 the United States Environmental Protection Agency
(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; and 
•	Making amendments to the Airborne Toxic Control Measure (ATCM)
to Limit Diesel-fueled Commercial Motor Vehicle Idling to expand
compliance responsibility.
The workshop is described further in the workshop notice at
http://www.arb.ca.gov/msprog/mailouts/msc1305/msc1305.pdf and
will be held at the following time and location: 
 Date:		Monday, March 11, 2013
Time:		8:30 a.m. – 4:00 p.m. 
Location:	Air Resources Board
			Coastal Hearing Room 
			1001 I Street
			Sacramento, California 95814

In September 2011, the 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,
California Code of Regulations, 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
section 2485 of title 13, California Code of Regulations, 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)
