ordiesel -- US EPA Waiver Granted to Enforce the In-Use Off-Road Diesel Vehicle Regulation Posted: 13 Sep 2013 15:27:05
The Air Resources Board (ARB) has received authorization from the United States Environmental Protection Agency (US EPA) to enforce the In-Use Off-Road Diesel Vehicle Regulation, including the regulationís performance standard requirements, such as turnover requirements and restrictions on adding Tier 0 and Tier 1 vehicles. Enforcement of the January 1, 2014 requirements for large fleets (> 5,000 total horsepower) will be delayed until July 1, 2014. The prohibition on adding vehicles with Tier 0 engines to any fleet and Tier 1 engines to large or medium fleets is effective on January 1, 2014. Enforcement Advisory 13-25 informs all off-road fleets as to how ARB staff will proceed with the enforcement of the regulation and is available on our website at http://www.arb.ca.gov/msprog/mailouts/msc1325/msc1325.pdf. To assist in planning and selecting compliance strategies to meet the January 1, 2014 requirements, large fleets are encouraged to use the fleet average calculator available at http://www.arb.ca.gov/msprog/ordiesel/documents/documents.htm. A Compliance Snapshot is also available to all off-road fleets in their Diesel Off-Road Online Reporting System (DOORS) account. The Snapshot displays the fleetís current standing in regards to the next compliance date, their upcoming requirements, and the amount of credits they have earned that can be applied towards meeting the requirements. For additional information about complying with the In-Use Off-Road Diesel Vehicle Regulation, including fact sheets, advisories, answers to frequently asked questions, and DOORS user guides, please visit our Knowledge Center at http://www.arb.ca.gov/msprog/ordiesel/knowcenter.htm, or call our DOORS helpline at 1-877-59DOORS (1-877-593-6677). 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, mining, and other industrial vehicles operating in California that have propulsion engines that are 25 hp or greater. Fleets were required to initially report their off-road diesel vehicles to ARB in 2009 via DOORS. In addition, fleet owners are currently subject to restrictions on unnecessary idling, and some large fleets will be subject to accelerated replacement/repower requirements beginning January 1, 2014. If you have any questions regarding the regulatory requirements, please contact the DOORS hotline at (877) 59-DOORS (877-593-6677) or by email at firstname.lastname@example.org.
