The Fleet Rule for Transit Agencies is the California Air Resources Board's effort to reduce both criteria pollutant emissions and exposure to toxic air contaminants from urban buses and transit fleet vehicles. The requirements for urban buses differ from the requirements for transit fleet vehicles. The regulation affects both public transit operators and heavy-duty engine manufacturers.

 December 2, 2009Online Annual Reporting is now available for use by agencies subject to the Fleet Rule for Transit Agencies. An annual report of a transit agency’s urban buses and transit fleet vehicles as of January 1, 2010 is due to ARB no later than January 31, 2010. The website for the Online Annual Reporting Database is found at: http://www.arb.ca.gov/msprog/bus/rptg/rptg.htm To access their fleet information, Transit Agencies will need the username and password created in the previous year’s login. If you misplaced your account information or in the event that ARB staff created your account on your behalf, you can access your user account by using the “forgot username” and “forgot/change password” links found on the login screen. If you need assistance logging in please contact Thelma Yoosephiance at tyooseph@arb.ca.gov or (626) 350-6407. Questions regarding regulation requirements and compliance should be directed to Eric Bissinger at ebissing@arb.ca.gov or (916) 324-9424. |
| October 13, 2009 The purpose of this advisory is notify transit agencies operating buses with gasoline engines in conjunction with hybrid systems certified to the urban bus service class of the specific conditions required to maintain the engine's certification. The specific conditions can be found in Mail-Out # MSC 09-34 online at: http://www.arb.ca.gov/msprog/mailouts/msc0934/msc0934.pdf |
| September 9, 2009 The purpose of this advisory is to remind transit agencies with over 30 urban buses who have opted to comply with the Urban Bus regulation by meeting the “diesel path” requirements. These fleets must mitigate oxides of nitrogen (NOx) emissions when purchasing model year 2007, 2008, or 2009 urban buses with engines certified above 0.2 grams per brake horse power-hour NOx [title 13, California Code of Regulations, section 2023.1(a)(5)]. More information can be found in Mail-out #MSC 09-28 online at: http://www.arb.ca.gov/msprog/mailouts/msc0928/msc0928.pdf |
| June 10, 2009 The Air Resources Board has verified the Johnson Matthey Advanced Catalyzed Continuously Regenerating Technology (ACCRT) system for select 2002 through 2006 model year heavy-duty diesel engines used in on-road applications including the 2003 model year Detroit Diesel Corporation's Series 60 heavy-duty engine, used in buses by many transit agencies. The ACCRT reduces emissions of diesel particulate matter by at least 85 percent and is designated as a Level 3 Plus system. Specific engine families and conditions for which the ACCRT system has been approved may be found in the Executive Order at: http://www.arb.ca.gov/diesel/verdev/verdev.htm |
