No. 09-0209\nDear Ms. Weightman:\nThis responds to your September 2, 2009 letter requesting clarification of requirements for\nloading tank cars with hazardous materials under the Hazardous Materials Regulations (HMR;\n49 CFR Parts 171-180). Specifically, you ask whether the tank car loading operation must be\nattended.\nSection 173.31 provides general requirements for transporting hazardous materials in tank cars,\nincluding tank car loading and unloading requirements. Additional requirements for loading\nand handling tank cars are in § 174.55. Section 174.67 establishes requirements for transloading\ntank cars that is, for transferring hazardous materials from one tank car to another tank car or\nfrom a tank car to a cargo tank motor vehicle or vice versa. Transloading operations must be\nattended in accordance with § 174.67(i); however, the HMR do not include specific\nrequirements for attending rail tank car loading operations.\nWe have initiated a rulemaking to consider whether additional measures are necessary to reduce\nthe risks associated with loading and unloading ofbulk packagings containing hazardous\nmaterials, including rail tank cars. We plan to publish a notice ofproposed rulemaking in 2010.\nI hope this answers your inquiry. If you need further assistance, do not hesitate to contact our\noffice.\nSincerely,\n'01t~\nCharles E.
