Diesel emissions control strategies (DECS) are used to control exhaust from diesel fleets.  The ARB’s verification procedure requires that a DECS manufacturer specify the fuel necessary for proper functioning of the DECS.  Use of any alternative diesel fuels and/or fuel additives not specifically listed in the DECS verification Executive Order is illegal and strictly prohibited.  Please read Advisory Number 379 which details the use of alternative diesel fuels and fuel additives in engines equipped with DECS:  /enf/advs/advs379.pdf

ARB is reminding transit agencies on the Alternative Fuel Path of the January 1, 2009 emission compliance deadline for particulate matter (PM) emissions.  The Urban Bus Regulation contained in title 13, California Code of Regulations, section 2023.1(e)(4) requires that no later than January 1, 2009, the diesel (PM) emission total for a transit agency on the alternative fuel path shall be no more than 15 percent of its diesel PM emission total on January 1, 2002 or equal to 0.01 g/bhp-hr times the total number of current diesel-fueled active fleet buses, which ever is greater.  Transit agencies on the alternative fuel path that have not reduced their PM emissions by 85 percent or met the 0.01 g/bhp-hr PM fleet average should develop PM emission reduction plans to meet this important requirement.  Questions regarding these requirements should be directed to Ms. Kathleen Mead, Manager, at (916) 324-9550, or Mr. Eric Bissinger, Air Pollution Specialist, at (916) 324-9424.

Fleet Rule for Transit Agencies Mail-Out #MSC-08-09 is now available.

California’s transit agencies need to be aware that some diesel engine manufacturers are legally selling engines that do not have high level particulate matter (PM) emission control systems. Because of this, these engines do not provide the emission reductions from 2007 model year and newer engines needed by transit agencies to meet the emission reduction requirements of the Fleet Rule for Transit Agencies.  While most new diesel engines are produced with high level PM emission control systems, some manufacturers are utilizing the averaging, banking, and trading program to certify some engines above the 0.01 g/bhp-hr PM emission standard.

Fleet Rule for Transit Agencies Mail-Out #MSC-08-06 is now available.

ARB has issued an advisory to remind transit agencies on the Alternative Fuel Path of the requirements associated with introducing new urban buses to their fleet.  Urban buses new to an Alternative Fuel Path fleet, including any leased vehicles, vehicles under contract, and newly purchased or acquired vehicles (new or used), must meet the alternative fuel purchasing requirement of 85% alternative fuel powered urban buses in a calendar year. This also includes all urban buses provided by private companies under contract to the transit agency.
