PHMSA NPRM on Standards and Operational Controls for High-Hazard Flammable Trains

Posted in on Thu, Aug 7, 2014

The Pipeline and Hazardous Materials Safety Administration (PHMSA), in coordination with the Federal Railroad Administration (FRA), is proposing new operational requirements for trains transporting a large volume of Class 3 flammable liquids, improvements in tank car standards, and revision of the general requirements for offerors to ensure proper classification and characterization of mined gases and liquids.  These proposed requirements are designed to lessen the frequency and consequences of train incidents involving transportation of large volumes of flammable liquids, highlighted by recent instances of trains carrying crude oil that derailed in Casselton, North Dakota; Aliceville, Alabama; and Lac-M[eacute]gantic, Quebec, Canada.  The changes also address National Transportation Safety Board (NTSB) safety recommendations on the accurate classification and characterization of such commodities, enhanced tank car construction, and rail routing.  Comments are due September 30, 2014.
