Marginal Way SW\nSeattle, WA 98106\nRef. No. 15-0107\nDear Mr. McElhoe:\nThis is a response to your April 15, 2015 email requesting clarification of the Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 171-180) with regard to the segregation of\nhazardous materials for vessel transport. Specifically, you request clarification on vessel\nstowage of \"UNO332, Agent blasting, Type E, Division 1.5D\" material and a \"UN1942,\nAmmonium nitrate, Division 5.1\" material in accordance with § 176.410(e) of the HMR.\nYour questions are paraphased and answered as follows:\nQ1. For vessel transport, can \"UN0332, Agent blasting, Type E, Division 1.5D\" material be\nstowed in the same freight container as \"UN1942, Ammonium nitrate, Division 5.1\" material?\nAl. The answer is yes. In accordance with § 176.410(e), ammonium nitrate and ammonium\nnitrate fertilizers classed as Division 5.1 (oxidizers) materials may be stowed in the same\nhold, compartment, magazine, or freight container with Class 1 (explosive) materials, except\nthose containing chlorates, in accordance with the segregation and separation requirements of\n§ 176.144 applying to \"Explosive, blasting, type B, Division 1.5D\" and \"Explosive, blasting,\ntype E, Division 1.5D\" (i.e.., Blasting agents). That is, the ammonium nitrate and ammonium\nnitrate fertilizers may be treated as Division 1.5D explosives and follow the\n§ 176.144 segregation and separation requirements for Class 1 (explosive) materials.\nQ2. If so, is segregation required between a freight container of \"UN1942, Ammonium\nnitrate, Division 5.1\" material and a freight container of UN0332, Agent blasting, Type E,\nDivision 1.5D?\"\nA2. The answer is no. Based on the § 176.410(e) allowance to treated the ammonium nitrate\nbe stowed in the same hold or compartment.\nas Division 1.5D explosives, the freight containers are not required to be segregated and may\n\n<<<PAGE 2>>>\n\nNote that whether stowed in the same freight container or separate freight containers, the\nentire load of material you described in your scenario must be treated as Division 1.5D\nblasting explosives in accordance with § 176.140(b).\nI hope this information is helpful. If you have any more questions, please do not hesitate to\ncontact this office again.\nSincerely\nNationte\nDirk Der Kinderen\nChief, Standards Development\nStandards and Rulemaking Division\n\n<<<PAGE 3>>>\n\nSuchak\n$176.41012)\nDodd, Alice (PHMSA)\nclan\nFrom:\n15-0107\nSent:\nGeller, Shelby CTR (PHMSA)\nTuesday, April 21, 2015 10:22 AM\nTo:\nHazmat Interps\nSubject:\nFW: Formal Letter of interpretation\nDear Shante and Alice,\nAttached is a formal letter of interpretation request.
