onrdiesel -- Public Notice Posted for Truck and Bus Regulation Workshops in December Posted: 14 Nov 2013 14:54:14
The California Air Resources Board (ARB or Board) invites you to participate in a series of public workshops to discuss proposed amendments to the In-Use On-Road Heavy-Duty Diesel-Fueled Vehicle regulation (Truck and Bus regulation). At its October 24, 2013, meeting, the Board directed ARB staff to develop a number of potential changes to the regulation that are intended to provide fleets additional flexibility in reducing their emissions and complying with the regulation. In developing these changes, staff intends to evaluate them to ensure that they result in emission levels that are similar to what would be expected from the current regulation, and that they do not jeopardize a region’s ability to meet federal air quality standards. The potential changes include: increasing low-use vehicle thresholds, allowing owners to newly opt-in to a number of existing flexibility provisions, expanding the regions that meet the definition of “NOx exempt,” and providing additional time for fleets in some rural areas to meet the regulation’s particulate matter requirements. At these workshops, staff will be soliciting input on the proposed amendments and the analytical methodologies that will be used in the supporting technical analysis. Staff plans to present final proposed amendments to the Board at its April 2014 meeting. For more information on the upcoming workshops, please see the notice available at: http://www.arb.ca.gov/msprog/onrdiesel/workshops.htm The workshops will be held in Diamond Bar on December 3, Sacramento on December 4, Redding on December 5, San Diego on December 10, and Fresno on December 12, 2013. For those unable to attend in person, a live internet broadcast (webcasting) will be available at our workshop on December 4, 2013. The broadcast can be accessed on the day of the workshop at http://www.calepa.ca.gov/broadcast/?BDO=1 An email address will also be available to submit questions or comments. The presentation, as well as any additional material, including proposed regulatory language, will be available prior to the workshop at: http://www.arb.ca.gov/dieseltruck The hard copy materials will also be available at each location on the day of the meeting. If you have questions regarding the workshop, please call our toll free diesel regulation information line at 1-866-6DIESEL (1-866-634-3735) or e-mail firstname.lastname@example.org. Background The regulation requires diesel truck and bus owners to take steps to reduce their engine emissions. The regulation is a part of the State's plan to meet federal ambient air quality standards and to protect public health, particularly near roadways and distribution centers where exposure frequently reaches unhealthy levels. Nearly all trucks and buses with a manufacturer's gross vehicle weight rating greater than 14,000 pounds that operate in California are required to be upgraded from 2012 to 2023 to reduce exhaust emissions. Most heavier trucks and buses (with a gross vehicle weight rating greater than 26,000 pounds) will be required to have a particulate matter filter by January 1, 2014. There are certain exceptions to these requirements for owners that have reported to use flexibility options allowed under the regulation. These include, but are not limited to, certain agricultural and limited-use construction trucks, low-use vehicles, and vehicles operated in certain rural areas.
