rulemaking submitted by industry representatives, requesting this action. Developing requirements for the HMR would provide wider access to the regulatory flexibility currently only offered by special permit and competent authorities. The HMR would authorize the transportation of certain explosives, ammonium nitrate, ammonium nitrate emulsions, and other specific hazardous materials in bulk packagings, which are not otherwise authorized under the HMR. These hazardous materials are used in blasting operations on specialized vehicles, purpose bulk trucks (MBTs). MBTs are used as mobile work platforms to create blends of explosives that are unique for each blast site. Effects: Prompting action: 2011 Retrospective Regulatory Review Rulemaking Project Initiated: 11/21/2011 Docket Number: PHMSA-2011-0345 Dates for NPRM: Federal Register Citation for NPRM: None Pipeline and Hazardous Materials Safety Administration 107. Popular Title: Enhanced Rail Tank Car Standards RIN 2137-AE91 Stage: NPRM Previous Stage: ANPRM published 9/6/2013; C/P extension published 11/5/2013; C/P closed 12/5/2013. Abstract: This rule proposes new operational requirements for certain trains transporting a large volume of flammable materials, 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 new requirements are designed to lessen the frequency and 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. These significant risks have been highlighted by the recent derailments of trains carrying crude oil in Casselton, North Dakota, Aliceville, Alabama, and Lac-Mégantic, Quebec, Canada. The proposed changes also address National Transportation Safety Board (NTSB) recommendations on accurate classification, enhanced tank cars, rail routing, oversight, and adequate response capabilities.
