bus-act -- Advanced Clean Transit Workgroup Materials Available

Posted: 28 Jan 2016 18:36:38
The agenda and supporting documents for the first Advanced Clean
Transit Workgroup are available now. The agenda and supporting
documents for the first Advanced Clean Transit Workgroup
(Workgroup) meeting have been posted at:
http://www.arb.ca.gov/msprog/bus/actmeetings.htm. A copy of these
materials was also emailed to active members.

As a reminder, the first Workgroup meeting will take place
tomorrow at the Cal/EPA Headquarters in Sacramento from 10:00
a.m. to 1:00 p.m. and is open to all interested parties.  The
meeting will be webcast and can be watched at:
http://www.calepa.ca.gov/broadcast/?BDO=1 .  During the webcast,
questions and comments can be sent via email to
sierrarm@calepa.ca.gov. The meeting will include a wide range of
stakeholders such as technology providers, original equipment
manufacturers, transit agencies, and other interested parties to
discuss the current status of advanced technologies for reducing
emissions from transit buses.  The focus of the Workgroup will be
to discuss solutions and barriers to implementing zero and
near-zero emission technologies in existing transit fleets and
how to leverage continued advancements in accelerating the market
for advanced technologies in the heavy duty sector.

If you have any questions regarding the Workgroup, please contact
Yachun Chow, Manager, Zero Emission Truck and Bus Section, at
yachun.chow@arb.ca.gov or at (916) 322-7450.  

Background

Adopted in 2000, the Fleet Rule for Transit Agencies required
reductions in diesel particulate matter and oxides of nitrogen
emissions from urban buses and transit fleet vehicles, and zero
emission bus purchases for transit agencies with 200 or more
urban buses.  Transit agencies that chose to follow the diesel
path option were required to demonstrate zero-emission buses,
with 15 percent of new buses purchased to be zero-emission
beginning in 2008.  For alternative path transit agencies, the 15
percent zero-emission bus purchase requirement was to begin in
2010.  The rule was amended in 2006, to postpone the purchase
requirement to 2011 for diesel path transit agencies, and 2012
for alternative path transit agencies, and to include an advanced
demonstration from the diesel path transit agencies.  At the July
2009 Board meeting, through Resolution 09-49, the Board directed
the Executive Officer to delay the zero-emission bus purchase
requirement due to technology readiness concerns, and to conduct
a technology assessment on the readiness of zero emission bus
technologies before reinstating purchase requirements.  In
January 2010, ARB issued an advisory (Mail-out #10-04) with the
postponement of the purchase requirement for zero-emission
buses.

Staff recently presented the technology assessment results of
fuel cell electric vehicles, battery electric vehicles, hybrid
vehicles, natural gas vehicles, and low NOx engines to the Board
in November 2015 with the commercialization stage of each
technology highlighted.  Staff concluded that low-NOx engines
will become commercially available soon and that zero emission
buses are in the early commercialization phase and have similar
performance and reliability as conventional buses. Therefore,
staff is currently in the process of working with stakeholders to
develop an Advanced Clean Transit proposal that will incorporate
these advanced clean technologies while transitioning public
transportation to zero emission technologies.
