Teas, PE\nVice President\nRef. No. 03-0035\nRiddick Engineering Corporation\n4600 West Markham\nLittle Rock, AR 72205\nDear Mr. Teas:\nThis is in response to your letter dated February 11, 2003, and subsequent telephone conversation with\nSandra Webb of my staff, requesting clarification of requirements for construction and certification of\nDOT 407 cargo tanks designed to be loaded by vacuum under the Hazardous Materials Regulations\n(HMR; 49 CFR Parts 171- 180). Specifically, you ask whether a cargo vacuum tank must be\ndesigned and manufactured with full ASME certification as provided in § 178.347-1(c) or to the\nprovisions outlined in § 178.347-1(d). You also ask if, when manufacturing under the provision\n§ 178.347-1(d), the manufacturer is required to be ASME certified as provided in § 107.503(b).\nSection 178.347-1(c) provides specific requirements for designing and constructing DOT 407 cargo\ntanks that are loaded by vacuum. Specifically it states, \"Any cargo tank built to this specification with a\nMAWP greater than 35 psig and each tank designed to be loaded by vacuum must be constructed and\ncertified in accordance with the ASME Code. The external design pressure for a cargo tank loaded by\nvacuum must be at least 15 psig.\" Therefore, a cargo tank designed to be loaded by vacuum must be\nconstructed and certified in accordance with the ASME Code. Additionally, in accordance with\n§ 178.345-1(d) a manufacturer of a cargo tank is required to hold a current ASME certificate of\nauthorization and must be registered with the Department in accordance with 49 CFR part 107 subpart\nF. This requirement applies if a cargo tank is designed and constructed under §178.347-1(c) or\n§ 178.347-1(d).\nI hope this information is helpful. If we can be of further assistance, please do not hesitate to contact us.\nSincerely,\nWain Hany\nSusan Gorsky\nSenior Transportation Regulations Specialist\nOffice of Hazardous Materials Standards\n178,347\n030035\n060-4-2-40\n\n<<<PAGE 2>>>\n\nTo: Edward Mazzullo\nFrom: Chris J.

Mobile vacuum tank. (SEE PICTURE BELOW)\n3.\n1500 gallon.\n4.\nInternal pressure < 15 psig.\nStainless steel.\n6.\n5.\nCustomer: US Government.\nUsed to clean up various hazardous spills.\nQuestions:\n1. Does this cargo vacuum tank need to be designed and manufactured with full ASME\ncertification per 178.347-1(c) or by ASME with exceptions per 178.347-1(d)?\n2. Regardless, we are designing this tank per ASME standards. However, if this tank\nfalls under (d), then does the manufacturer have to be ASME certified as listed in\n107.503(b)?\nSincerely,\nChris J.
