No. 01-0294\nUS Army Defense Ammunition Center\n1 C Tree Road\nMcAlester, OK 74501-9053\nDear Mr. Frerichs:\nThis responds to your November 19, 2001 letter requesting additional clarification of our response\nletter Ref. No. 01-0280 regarding segregation requirements under the Hazardous Materials Regulations\n(HMR; 49 CFR Parts 171-180). Specifically, you ask whether a dromedary unit that is attached to a\nHeavy Expanded Mobility Tactical Truck with a Load Handling System (HEMTT-LHS), equipped\nwith a flatrack with cargo, is considered to be a separate transport vehicle from the dromedary box.\nYou intend to transport incompatible explosives separated in this manner.\nIt is the opinion of this Office that a dromedary box loaded with explosives attached to a HEMTT-LHS\nthat also has a flatrack loaded with explosives is considered to be one transport vehicle, and, is not\nacceptable for hazardous materials, including incompatible explosives, that may not be transported on\nthe same transport vehicle under § 177.848. However, if the flatrack loaded with explosives is loaded\nonto a separate trailer attached to the back of the HEMTT-LHS, the combination motor vehicle is\nconsidered to be two separate transport vehicles, and is acceptable for hazardous materials that require\nsegregation of incompatible explosives on the same transport vehicle.\nI hope this additional clarification on transporting incompatible explosives is helpful.\nSincerely,\nDelmer F.

Billings\nOffice of Hazardous Materials Standards\n400 7* Street SW\nWashington, DC 20590\nSUBJECT: Request for Clarification of Response Letter\n1. This is a request for a clarification to your response letter dated Oct 30, 2001\n(Ref. No:01-0280).\n2. The DROM box with the incompatible explosive items is attached directly to\n(HEMTT-LHS). The HEMTT-LHS vehicle transports the primary cargo on the\nthe Heavy Expanded Mobility Tactical Truck with the Load Handling System\ndemountable flatrack. Once the HEMTT-LHS arrives at destination, the flatrack\nwith cargo is offloaded to the ground and the HEMTT-LHS with the DROM box\nand incompatible items drives away.\n3. This office believes that the HEMTT-LHS with the DROM box is considered a\nseparate transportation vehicle from the demountable flatrack with cargo.\n4. Are we correct in our interpretation that the HEMTT-LHS with the DROM box\nand incompatible items is a separate transportation vehicle from the\ndemountable flatrack with cargo? Also, does the HEMTT-LHS equipped with the\nDROM box with incompatible items comply with the 49 CFR, section 177.848,\nSegregation of Hazardous Materials?\n5. Enclosed are your response letter, our original request letter, and the\nbackground information on dromedary box and the HEMTT-LHS vehicle.\n6.
