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.

The California Air Resources Board (ARB) has extended the verification for the Proventia Group’s FTF and Bobtail FTF to cover model year (MY) 2003 transport refrigeration unit (TRU) engines.

This action was taken in anticipation of ARB’s planned amendment to the TRU Airborne Toxic Control Measure (ATCM), which will change the in-use performance standard for MY 2003 engines from the Ultra-Low Emission TRU in-use performance standard to the less stringent Low-Emission TRU (LETRU) in-use standard.  MY 2003 TRU engines are required to comply with this in-use standard by December 31, 2010.

The Proventia FTF and Bobtail FTF flow-through filters reduce diesel particulate matter emissions at least 50 percent, plus they comply with the 20 percent NO2 limit, qualifying it as a Level 2 Plus Verified Diesel Emissions Control Strategy (VDECS).

This verification allows the FTF and Bobtail FTF Level 2 VDECS to be used as a retrofit compliance option to meet the TRU ATCM’s LETRU in-use standard.  It can be used on Thermo King TRUs with MY 1987 through 2003 truck TRU engines and MY 1985 through 2003 trailer TRU engines, provided certain terms and conditions are met.  TRU owners should read about the specific terms and conditions for which the Proventia FTF and Bobtail FTF have been approved in Executive Order DE-08-001-04, which will be posted the week of July 19, 2010, on the ARB Verification Procedure – Level 2 website at http://www.arb.ca.gov/diesel/verdev/level2/level2.htm.  The list of engines that can be matched with this filter will also be posted there as an attachment.

On Tuesday, November 10th, the second meeting of the California Air Resources Board’s Truck Regulations Advisory Committee (TRAC) and its designated subcommittees will be held. The main TRAC meeting will be held from 3-5 PM PST in the Sierra Hearing Room at the CALEPA Building in Sacramento, CA and webcast.

Background on the TRAC:

The California Air Resources Board (CARB) created the Truck Regulations Advisory Committee (TRAC) as part of its implementation of the Truck and Bus regulation and the Heavy-Duty Diesel Greenhouse Gas Emission Reduction regulation.  TRAC was formed to assist CARD in facilitating communication with stakeholders and to obtain stakeholder feedback on the implementation tools used for these regulations. According to CARB, The goals of TRAC is to help CARB staff fine tune its outreach, training, and implementation materials and provide a mechanism for stakeholders to discuss other implementation issues.
