Specifically, you\nask whether \"UN1067, Dinitrogen tetroxide, inhibited, 2.3,\" may be shipped in a Department of\nTransportation (DOT) 110 multi-unit tank car tank under the provisions in § 173.314(c). You\nreference a final rule published on January 13, 2009 (74 FR 1787; HM-246) in which the\npreamble states, \"Multi-unit tank car tanks and forged-welded tank car tanks (e.g., DOT 106,\nDOT 109, and DOT 110) may continue to be used as authorized.\"\nThe answer is yes. \"UN1067, Dinitrogen tetroxide, inhibited, 2.3,\" may be shipped in a\nDOT 110 multi-unit tank car tank under the provisions in § 173.314(c). Note 11 was added to\nthe § 173.314(c) table to clarify that for tank cars built prior to March 16, 2009, and used to\ntransport PIH materials, the then-current class of authorized tank cars may continue to be used,\nprovided the tank cars were approved by the AAR Tank Car Committee for transportation of the\nspecified material. DOT 110 multi-unit tank car tanks were authorized for dinitrogen tetroxide at\nthat time. Multi-unit tank car tanks and forged-welded tank car tanks (e.g., DOT 106, DOT 109,\nand DOT 110) were not affected by the 2009 final rule and may continue to be used as\nauthorized.\nThank you for bringing this typographical error to our attention. We intend to correct it in a\nfuture rulemaking action.\nI hope this information is helpful. Please contact us if we can be of further assistance.\nSincerely,\nT.

Note\nB66 in 172.102 still authorizes stainless steel 110 multi-unit tank car tanks in the\nregulations and the change is only reflected in Part 173.314. Furthermore, we believe that\nthe changes made apply to single unit tank car tanks only, not to multi-unit tank car tanks.\nMulti-unit tank car tanks are no longer included in the AAR Manual of Standards &\nRecommended Practices, Section C-111 Specification for Tank Cars M-1002.\nIf you have questions or comments, please contact me at Ph. 330-482-3373 / E-mail:\ntinac@cbco.com\nSincerely,\nLuva Cousis\nTina Cousins\nProduct Manager\nColumbiana Boiler Company, LLC 200 West Railroad Street, Columbiana, OH 44408 USA\nTel 330-482-3373 Fax 330-482-3390 Email sales@cbco.com Web www.cbco.com","truncated":false,"body_characters":3871}
