Rumph\n'umter Transpor\nRef. No. 00-0010\n70 South Lafayette Driv\nSumter, South Carolina 29150\nDear Mr. Rumph:\nThis responds to your letter, dated October 29, 1999, concerning cargo tank specification\nrequirements in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).\nSpecifically, you ask about a design modification to MC 307, MC 312, DOT 407, and DOT 412\nspecification cargo tanks to equip them with an internal agitation system driven by a power\nsource located outside the cargo tank.\nYour letter suggests that you are considering manufacturing new cargo tanks equipped with the\ninternal agitation system rather than modifying existing cargo tanks. You should be aware that\nMC 307 and MC 312 specification cargo tanks have not been authorized for new construction\nsince August 31, 1995 (see § 180.405(b)).\nThe design and construction requirements for DOT 407 and DOT 412 specification cargo tanks\nare in § 178.345 of the HMR. The regulations do not prohibit a design of the type you describe.\nEach cargo tank motor vehicle design type must be approved by a Design Certifying Engineer\n(see § 178.320(b)). In addition, each finished cargo tank motor vehicle must be inspected by an\nAuthorized Inspector or a Registered Inspector, as applicable (see § 178.345-1(e)).\nGenerally, MC 307, MC 312, DOT 407, and DOT 412 specification cargo tanks are authorized\nfor bulk shipments of flammable liquids, including waste flammable liquids. Packaging\nrequirements for bulk quantities of a specific hazardous material can be found in column 8(C) of\nhe Hazardous Materials Table in 8 172.101 of the HMR. You should consult the section of th\nHMR referenced in column 8(C) for the specific hazardous material you are transporting for the\npackagings authorized for transportation and any special requirements that also apply.\n000010\n178.345\n\n<<<PAGE 2>>>\n\nSubpart B - Preparation of Hazardous Materials for Transportation.\nAdditional requirements for transporting bulk quantities of hazardous materials are in Part 173,\nthis office.\nI hope this information is helpful. If you have further questions, please do not hesitate to contact\nSincerely,\nTh\norn t. Allan\nThomas G.
