To address stakeholder requests, the California Air Resources Board (CARB) staff announced on Tuesday, August 3, 2010, that it is postponing consideration of regulatory amendments until November, 2010.  It also announced that itwill be scheduling additional workshops in August/September to discuss the emissions inventory and proposed amendments.

When CARB Staff held workshops in June and July regarding proposed amendments to the Truck and Bus, Off-Road, Tractor-Trailer GHG, and Drayage Truck regulations many stakeholders requested additional time to review and comment on the regulations, including the following:

  • Details of planned emissions inventory updates for trucks and off-road vehicles,
  • Specific draft regulatory language,
  • ARB’s revised report on fine particulate matter (PM2.5) mortality estimates, a draft of which will be released later this summer, and
  • Proposed changes to the Drayage Truck Regulation.

To address those requests, CARB decided to move the Board Hearing to consider the proposed amendments, currently slated for September 2010, to November.  In the interim, CARB staff will hold workshops in August and September to discuss the revised emission inventory and the proposed amendments.  CARB says it believe that this delay in the hearing date will provide sufficient time to hold the workshops and to make any necessary adjustments after the workshops.

Background on the Regulations to Be Considered

The Truck and Bus, Off-Road, and Drayage Truck Regulations are intended to reduce toxic and smog-forming emissions from trucks, buses, and off-road vehicles. Reducing such emissions is necessary to meet federally imposed clean air standards and to reduce the adverse health effects from air pollution throughout the state. The Tractor-Trailer GHG regulation is intended to reduce greenhouse gas emissions from tractor-trailers traveling California’s roadways.

While staff is proposing to amend several elements of the truck and bus and off-road regulations, many provisions are in effect and not being considered for amendment.  These include:

  • Off-road reporting and labeling requirements;
  • Off-road idling limits and sales disclosure requirements; and
  • Requirements to report vehicles utilizing the agricultural vehicle provisions and some two engine street sweepers under the truck and bus regulation.

However, due to the pending amendments to the truck and bus and off-road regulations, several requirements have been postponed:

  • On February 11, 2010, CARB issued a delay of the off-road regulation’s retrofit and turnover requirements pending further notice.
  • The truck and bus regulation reporting originally required by March 31, 2010, has been delayed until early 2011.
  • The truck and bus retrofit and turnover requirements (scheduled to begin January 1, 2011) will also be extended.
