Public Transit Agencies

This page last reviewed December 16, 2011


Background:


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.

  • Online Annual Reporting is now available for 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, 2011 is due to ARB no later than January 31, 2011.

    The website for the Online Annual Reporting Database is updated. 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.

  • The Air Resources Board is reminding transit agencies operating Transit Fleet Vehicles (TFV) as defined under title 13, California Code of Regulations (CCR), section 2023 (12) of the December 31, 2010 emission reduction deadline for particulate matter (PM) and oxides of nitrogen (NOx) emissions.  The TFV Regulation contained in title 13, CCR, section 2023.2 requires that no later than December 31, 2010:
  1. the diesel PM emission total for a transit agency shall be no more than 20 percent of its diesel PM emission total on January 1, 2005 or equal to 0.01g/bhp-hr times the total number of current diesel-fueled active fleet buses, which ever is greater, and
  2. the NOx fleet average shall not exceed 2.4 g/bhp-hr or be void of 2001 and earlier model year engines.
  • Transit agencies operating TFVs that have not reduced their PM emissions by 80 percent or met the 2.4 g/bhp-hr NOx fleet average should develop emission reduction plans to meet this important requirement.  

    Questions regarding these requirements should be directed to Mr. Eric Bissinger, Air Pollution Specialist, at (916) 324-9424.
