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

will be held at the following time and location:

Background: 

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.
