2137-AE91 201510 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 2137 Pipeline and Hazardous Materials Safety Administration PHMSA 2100 Department of Transportation DOT Hazardous Materials: Enhanced Tank Car Standards and Operational Controls for High-Hazard Flammable Trains

This rulemaking would amend operational requirements for certain trains transporting a large volume of flammable materials, provide improvements in tank car standards, and revise the general requirements for offerors to ensure proper classification and characterization of mined gases and liquids. These new requirements are designed to lessen the consequences of derailments involving ethanol, crude oil, and certain trains transporting a large volume of flammable materials. The growing reliance on trains to transport large volumes of flammable materials poses a significant risk to life, property, and the environment. The proposed changes also address National Transportation Safety Board (NTSB) recommendations on accurate classification, enhanced tank cars, rail routing, oversight, and adequate response capabilities.
