Rail Emission Reduction Program      

This page last reviewed January 27, 2014

The Air Resources Board (ARB) has developed and implemented a number of measures to significantly reduce locomotive and railyard emissions in California, including regulations, enforceable agreements, and funding of clean technology.  Information on these efforts can be found below.

Proposed Commitments


CommitmentsThe Commitments are proposed binding voluntary agreements between ARB and the railroads (UP and BNSF) that are applicable to four high priority railyards in the South Coast Air Basin:  BNSF San Bernardino, BNSF Hobart, UP Commerce, and UP ICTF/Dolores.  The proposed Commitments would require the four high priority railyards to reduce 2005 diesel particulate matter (PM) emissions by 85 percent or more, irrespective of growth, by 2020.


1998 Agreement


1998agreementThe Locomotive Fleet Average Agreement was signed by ARB, UP, and BNSF in 1998. The 1998 Agreement requires cleaner locomotives to operate in Southern California between 2010 and 2030. In combination with U.S. EPA regulations for cleaner locomotives, the 1998 Agreement is estimated to provide the South Coast Air Basin with a 65 percent reduction (up to 24 tons per day in locomotive NOx emissions) between 2000 and 2010.   


Railyard Health Risk Assessments and Mitigation Plans

What's New?Under provisions of 2005 Statewide Railyard Agreement, UP and BNSF were required to collect diesel PM emission inventory data and conduct air dispersion modeling for 17 major railyards.  Based on this information, the ARB prepared health risk assessments for the 17 major railyards.  The health risk assessments were critical in identifying risk reduction measures and in the development of draft mitigation plans.


2005 Statewide Railyard Agreement


2005CommitmentsThe Statewide Railyard Agreement between ARB, UP, and BNSF was signed by the ARB Executive Officer in June 2005.  The Agreement required UP and BNSF to reduce diesel particulate matter emissions in and around UP and BNSF railyards throughout the state by up to 20 percent between 2005 and 2008.  The Statewide Railyard Agreement also required the preparation of health risk assessments and mitigation plans (see above).


Regulatory Activity


carbdieselfuelregulationSince 2004, ARB has approved several regulations that significantly reduce diesel emissions in and around railyards throughout the state.

Locomotive Technology Demonstrations and Emission Verifications
