California Asked EPA for More Stringent Federal Emission Standards for Locomotives. On April 13, 2017, the California Air Resources Board sent a letter to EPA Administrator Scott Pruitt requesting that EPA adopt more stringent emission standards for locomotives. CARB said its proposed standard could achieve 99% control of emissions of nitrogen oxides and diesel particulate matter, 98% control of hydrocarbon emissions, and 10–25% control of greenhouse gas emissions. The proposed standards would apply to newly built and remanufactured locomotives and locomotive engines.
