ordiesel -- Off-road Diesel Regulation – New Guidance and Fleet Average Calculator
Posted: 19 Feb 2009 16:55:24
ARB staff have released new guidance regarding on-road engines in off-road vehicles as a strategy to comply with the regulation, clarifications regarding the applicability of the regulation, and a new fleet average calculator that allows fleets to analyze the hours of operation in fleet average option. Guidance Regarding Off-road Regulation ARB staff have added to the growing list of answers to frequently asked questions, and regulation advisories, with new guidance documents that may help fleets comply with the regulation. The new additions address: • How on-road certified engines, which generally have lower emissions than off-road engines, may be used when repowering an off-road vehicle to lower emissions. • General applicability of the regulation, including how it applies to snow removal equipment and to vehicles operated both inside and outside California. • How electric GSE may be reported for partial credit towards the regulation. • How to determine fleet size for private businesses and corporations. • How the regulation may provide extensions for fleets with vehicles on order from manufacturers, where receipt has been delayed. Guidance is also available on-line related to the following topics: Regulation overview, idling limits and idling policy guidelines, disclosure for vehicle sales, labeling, agriculture vehicles, yard trucks, public fleet size, portable equipment, and compliance examples. Available at: http://www.arb.ca.gov/msprog/ordiesel/knowcenter.htm New Fleet Average Calculator Additionally, staff have released a new version of the fleet average calculator that allows fleets to calculate the effect of including the hours of operation from their equipment. Fleets which have newer equipment which they use a large number of hours, and older equipment which is used much less, may find that reporting the hours of operation for their fleet will make complying with the regulation easier and less costly. The new calculator - available at http://www.arb.ca.gov/msprog/ordiesel/documents/documents.htm#fleet - will help fleets determine if this option is beneficial for them. Note that reporting the hours of use is optional, and this calculator does not replace the previous version except for fleets using the hours of operation provision.
