Proposed Commitments to Further Reduce Diesel PM Emissions at Four High Priority Railyards
This page last revised March 26, 2013The Commitments are proposed binding voluntary agreements between the Air Resources Board (ARB), BNSF Railway (BNSF), and Union Pacific Railroad (UP) that cover 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 reduce the four high priority railyards' 2005 diesel PM emissions, irrespective of growth, by 85 percent or more by 2020.
IntroductionIn June 2010, Air Resources Board staff released a report entitled Proposed Actions to Further Reduce Diesel Particulate Matter at High Priority California Railyards (June 2010 Report) with a proposal to further reduce emissions of toxic diesel particulate matter (PM) at four railyards in Southern California with high estimated health risks. We refer to these as the Proposed Commitments.
Public Notice of 15-Day Extension for the CEQA Functional Equivalent DocumentThe public comment period was extended to September 6, 2011. (PDF - 47KB) Supplement to the June 2010 Staff Report on Proposed Actions to Further Reduce Diesel Particulate Matter at High Priority California Railyards provides updated material. This supplement presents ARB staff's revised estimates of diesel PM emissions and health risk at each railyard. The analysis quantifies the significant reduction in diesel PM emissions and health risk at each railyard between 2005 and 2010. The supplemental report also includes the latest draft of the Proposed Commitments between the Air Resources Board and Union Pacific Railroad and BNSF Railway to Further Reduce Diesel Particulate Emissions at Four High-Priority Railyards (Proposed Commitments) for each railyard as well as an environmental assessment of the Proposed Commitments (see below).
There was a 45-day public comment period for the CEQA FED from July 5, 2011 to August 19, 2011 at 5:00 PM.

- Staff Recommendations to Provide Further Locomotive and Railyard Emission Reductions (PDF-487kb)
This revised report was intended only to provide a technical assessment of various options that were available in 2009 or may be available in the near future to accelerate and provide additional emissions reductions from locomotives and major railyards in California. It was not intended to serve as an implementation blueprint, as it does not evaluate which agency or agencies may have authority to implement such options. The document also does not evaluate what role, if any, the availability of public funding might play in assuring earlier or further reductions.
Staff also acknowledges that the data used in this report represents a snapshot in time. Elements such as locomotive fleet composition data are fluid and are influenced by many factors. In addition, other data used to evaluate technological feasibility, potential emission reductions, and costs are also fluid and subject to change. The staff expects to provide updates to this 2009 document as technology developments and demonstration project results warrant.
