ordiesel -- ARB Off-Road Regulation: Two engine vehicles and labeling updates Posted: 09 Jul 2012 10:49:32
Many diesel on-road vehicles with two-engines are subject to the Off-Road Regulation and must be reported to the Air Resources Board (ARB), and all vehicles subject to the regulation must be labeled on both sides by January 1, 2013. We are reissuing the note sent this morning to the ordiesel listserve, which had an inadvertent formatting problem and some unclear wording. We apologize for any inconvenience. The corrected note is below. Many diesel on-road vehicles with two engines are subject to the Off-Road Regulation and must be reported to the Air Resources Board (ARB), and all vehicles subject to the regulation must be labeled on both sides by January 1, 2013. Amendments to the Off-Road Regulation approved in 2010 make both engines of many on-road two-engine vehicles subject to the regulation. On-road two-engine vehicles that meet both the following criteria are subject to the Off-Road Regulation, and if not yet reported, must be reported immediately or face enforcement action: * Have a gross vehicular weight > 14,000 pounds; and * Have an auxiliary engine >= 50 brake horsepower that is permanently attached and integrated into the design of the vehicle. These requirements do not apply to two-engine on-road sweepers, as those vehicles are subject to the On-Road Truck and Bus Regulation, nor to vehicles that are subject to the Fleet Rule for Public Agencies and Utilities. All two-engine cranes and water well drilling rigs continue to be subject to the Off-Road Regulation. More information on this requirement is available at http://www.arb.ca.gov/msprog/ordiesel/regadv/adv1202b.pdf. Effective January 1, 2013, all vehicles subject to the Off-Road Regulation will be required to have both sides labeled with their Equipment Identification Number (EIN). All vehicles newly reported to ARB must now be labeled on both sides within 30 days of receiving the EIN and all previously reported vehicles must be labeled on both sides by January 1, 2013. For more information about labeling on both sides of a vehicle or the off-road regulation, visit the off-road regulation website at http://www.arb.ca.gov/msprog/mailouts/msc1208/msc1208.pdf. Also effective January 1, 2013, designated Captive Attainment Area Fleets are required to label their vehicles with EINs that have white lettering with a green background (rather than white on red). All Captive Attainment Area Fleets newly reported to ARB must now be labeled on both sides within 30 days of receiving the EIN, and all previously reported vehicles must be labeled on both sides by January 1, 2013. Captive attainment area fleets are treated as small fleets even if their total horsepower (hp) exceeds the small fleet threshold of 2,500 hp. More information about how the labels must appear is available at http://www.arb.ca.gov/msprog/ordiesel/faq/faq-labeling.pdf. Background The regulation for In-Use Off-Road Diesel Vehicles first became effective under California law on June 15, 2008. This regulation is intended to reduce harmful emissions from diesel powered construction and mining vehicles operating in California and having propulsion engines that are 25 hp or greater. Fleets were required to initially report their off-road diesel vehicles to ARB in 2009 via the Diesel Off-road On-line Reporting System (DOORS). In addition, fleet owners are currently subject to restrictions on unnecessary idling, and will be subject to accelerated replacement/repower requirements beginning January 1, 2014, If you have any questions regarding off-road reporting, please contact the DOORS hotline at (877) 59-DOORS (877-593-6677) or by email at email@example.com.
