Hazardous Materials: Improving the Safety of Railroad Tank Car Transportation of Hazardous Materials

SUMMARY: On April 1, 2008, PHMSA, in consultation with the Federal Railroad Administration (FRA), published a notice of proposed rulemaking (NPRM) proposing revisions to the Federal Hazardous Materials Regulations to improve the crashworthiness of railroad tank cars designed to transport poison inhalation hazard (PIH) materials. Specifically, the NPRM proposes enhanced tank car performance standards for head and shell impacts; operational restrictions for trains hauling tank cars containing PIH materials; interim operational restrictions for trains hauling tank cars containing PIH materials, but not meeting the enhanced performance standards; and an allowance to increase the gross weight of tank cars that meet the enhanced tank-head and shell puncture-resistance requirements. This notice announces that PHMSA and FRA will hold a series of public meetings (May 14, 15, 28, and 29, 2008 in Washington, DC) related to the NPRM. Information on the scope, topics, dates, and locations of these public meetings is provided in this notice.
