No. 08-0 125\nDear Mr. Shelton:\nThis is in response to your May 3,2008 letter requesting clarification of the Hazardous Materials\nRegulations (HMR; 49 CFR Parts 171-1 80) applicable to registration and recordkeeping\nrequirements pertaining to Department of Transportation (DOT) specification cargo tanks.\nYour questions are paraphrased and answered as follows:\nQ1. Do the registration requirements specified in Part 107, Subpart F of the HMR apply to a\ncompany that performs a Wet Fluorescent Magnetic Particle Examination (WFMPE) on\nMC 330 and MC 33 1 cargo tanks?\nA l . Yes. In accordance with § 107.502, no person may engage in the manufacture, assembly,\ncertification, inspection or repair of a cargo tank or cargo tank motor vehicle\nmanufactured under the terms of a DOT specification or a special permit unless the\nperson is registered with the Department in accordance with the provisions of Subpart F.\nA person employed as an inspector or design certifying engineer is considered to be\nregistered if the person's employer is registered.\n42. Section V of the ASME code requires a written report when a WFMPE is performed. Is\na written report required as part of the pressure test when a WFMPE is performed, or is it\nallowable to indicate on the pressure test report required by'$ 180.41 7 that a WFMPE\nwas completed?\nA2. In accordance with Section V of the ASME Code, a written report is required when a\nWFMPE is performed. In addition, each person performing a test or inspection specified\nin 5 180.407 must prepare a written report in accordance with the reporting and\nrecordkeeping requirements specified in 5 180.4 17.\n43. Section V of the ASME Code requires specific qualification and training requirements\nand documentation for persons performing a WFMPE. Are these documents required to\nbe maintained and produced in accordance with the requirements of Section V of the\nASME Code?\n\n<<<PAGE 2>>>\n\nA3. Yes.\n44. A4. Q5. A5. What DOT regulations require the maintenance of the additional documentation\nreferenced in Q3?\nAs required in 8 180.407(g)(3), the wet fluorescent magnetic particle inspection must be\nin accordance with Section V of the ASME Code and CGA Technical Bulletin TB-2.\nCGA Technical Bulletin TB-2, Section 5.6 states: \"Determine the proper documentation\nhas been completed, including marking of the tank. Refer to 49 CFR 180.41 5 and\n180.41 7.\" Is this documentation required by the ASME Code or the HMR?\nThe HMR incorporate Section V of the ASME Code by reference. Thus, when a\nWFMPE is performed, the HMR require a written report in accordance with Section V.\nIn addition, the requirements of test and marking requirements specified in 8 180.41 5 and\nthe reporting and record retention requirements specified in 8 180.41 7 must also be met.\nI hope this information is helpful.\nSincerely,\nSusan Gorsky, U\nActing Chief, Standards Development\nOffice of Hazardous Materials Standards\n\n<<<PAGE 3>>>\n\n/\n10104 Creedmoor Road K9isbaii bvl/b~\nRaleigh, N.C. 27615 08-0125\nMay 3,2608\nMr. Edward Mazzullo\nOffice Director, Office of Hazardous Materials Standards\nU.S. Department of Transportation\nPipeline and Hazardous Materials Safety Administration\nEast Building, 2nd Floor\nMail Stop: E21-3 17\n1200 New Jersey Ave., SE\nWashington, DC 20590\nMr. Mazzullo,\nPlease accept this letter as our request for an interpretation of the registration\nrequirements in 49 CFR 107.502(b) which states in part the following:\n\"(b) No person may engage in the manufacture, assembly, certification, inspection or\nrepair of a cargo tank or cargo tank motor vehicle manufactured under the terms of a\nDOT specification under subchapter C of this chapter or a special pennit issued under\nthis part unless the person is registered with the Department in accordance with the\nprovisions of this subpart.. . .\"\nI have attached for your reference e-mail correspondence dated October 6,2004 which\nstates that a person performing a welded repair to the cargo tank wall must have a CT\nnumber. I am sorry that the question was not in the attached e-mail but the question that\nprompted this response was this:\n\"If a facility that is registered with the Department does not have an \" R stamp, can they\nsub-contract the welded repair to a company that has an \" R stamp but does not have a\nCT number\"\nI addition, I have attached for your reference interpretation 05-0071 dated April 27,2005\nwhich further supports the Departments' position and creates the appearance that, even\nthough a CT number is only a registration requirement, this interpretation states very\nclearly that without a CT number you are not AUTHORIZED (emphasis added) to\nFax (877) 841 -6023 Phone (423)863-2252\n\n<<<PAGE 4>>>\n\nperform any function where registration is required. So, in effect, a CT number is an\nauthorization to perform any of the functions where registration is required. I have also\nprovided for your reference materials incorporated by reference CGA P-26 (formerly TB-\n2 titled Guidelines for Inspection and Repair of MC 330 and MC 33 1 anhydrous\nammonia cargo tanks) and Section V article 7 of the ASME code.\nMC 330 and 331 cargo tank motor vehicles are generally required to undergo a pressure\ntest at certain intervals. The requirements in 49 CFR 1 80a407(g)(3)state as follows:\n\"Each MC 330 and MC 33 1 cargo tank constructed of quenched and tempered steel in\naccordance with Part UHT in Section VIII of the ASME Code (IBR, see $ 17 1.7 of this\nsubchapter), or constructed of other than quenched and tempered steel but without\npostweld heat treatment, used for the transportation of anhydrous ammonia or any other\nhazardous materials that may cause corrosion stress cracking, must be internally\ninspected by the wet fluorescent magnetic particle method immediately prior to and in\nconjunction with the performance of the pressure test prescribed in this section. Each MC\n330 and MC 33 1 cargo tank constructed of quenched and tempered steel in accordance\nwith Part UHT in Section VIII of the ASME Code and used for the transportation of\nliquefied petroleum gas must be internally inspected by the wet fluorescent magnetic\nparticle method immediately prior to and in conjunction with the performance of the\npressure test prescribed in this section. The wet fluorescent magnetic particle inspection\nmust be in accordance with Section V of the ASME Code and CGA Technical Bulletin\nTB-2 (IBR, see $171.7 of this subchapter). This paragraph does not apply to cargo tanks\nthat do not have manholes. (See $180.4 17(c) for reporting requirements.)\nQuestion 1: Not all MC 330 and MC 33 1 cargo tanks requ.ired a Wet Fluorescent\nMagnetic Particle Examination (WFMPE) immediately prior to and in conjunction with a\npressure test so it appears this WFMPE is an additional test that must be performed.\nBecause this non destructive testing (NDE) is very technical in nature most facilities\ncontract this service out to companies that specialize in NDE. Because this is a separate\ntest, is the person who performs the WFMPE required to be registered with the\nDepartment and get a CT number.\nThe WFMPE must be performed in accordance with Section V of the ASME Code and\nCGA Technical Bulletin TB-2. The following questions refer to these documents:\nQuestion 1 : Section V of the ASME Code requires a written report. Is a written report\nrequired as part of the pressure test when a WFMPE is performed or can one simply say\non the pressure test report required by 180.417 that a WFMPE was completed?\nQuestion 2: Section V of the ASME Code requires specific qualification and training\nrequirements and documentation for anyone performing a WFMPE. Are these\ndocuments required to be maintained and produced in accordance with the requirements\nof Section V of the ASME Code?\n\n<<<PAGE 5>>>\n\nQuestion 3: Regarding the qualification and training documents reference in Question 2,\nwhat DOT regulations would require me to maintain these additional qualification\ndocuments over and above what is currently required in 49 CFR 172.704(d).\nQuestion 4: CGA Technical Bulletin TB-2 Section 5.6 states as follows: \"Determine the\nproper documentation has been completed, including marking of the tank. Refer to 49\nCFR 180.4 1 5 and 180.4 17. What proper documentation is this bulletin referring to? Is it\nthe documentation required by Section V of the ASME Code, the documentation required\nin 180.41 7(b), the documentation required in 180.41 7(c), none of the above, all of the\nabove or some combination?\nThank you in advance for your reply.\nSincerely\nDaniel G.

Repair is defined in 49 CFR Part 5\n180.403 as any welding on a cargo tank wall done to return a cargo tank or a\ncargo tank motor vehicle to its original design and construction specification,\nor to a condition prescribed for a later equivalent specification in effect at\nthe time of the repair. The repair function is identified in 49 CFR Part 5\n107.502 as a function where registration is required. 49 CFR § 107.502(b)\nspecifically states that no person may engage in the manufacture, assembly,\ncertification, inspection or repair of a cargo tank or cargo tank motor vehicle\nmanufactured under the terms of a DOT specification under subchapter C of this\nchapter or an exemption issued under this part unless the person is registered\nwith the Department in accordance with the provisions of this subpart. The\nshort version of this is if you are performing a function where registration is\nrequired, you need to be registered with the Department. There is no cost to\nthe registration process and places no unnecessary burden on the public.\nI hope this information is helpful.\nJoe\nJoseph Solomey\nResearch and Special Programs Administration Assistant Chief Counsel Hazardous\nMaterials Safety and Emergency Transportation Law Division 400 7th.

Specifically, you ask several questions regarding the testing\nrequirements for a DOT Specificati~n 406 CTMV. In addition, you indicate that the\ncargo tank does not meet the requirements prescribed in Part 278, Subpart 5 for the\nspecification.\nYour questions are paraphrased and answered as follows:\nQ1. May a company that is not registered with the D~partment, in accordance with\nPart 107, Subpart F, manufactme a DOT Specification 406 CTMVS\n' A1 . No. The definition of a ~atldacturer provided in 5 178.320 states that a\nmanufa~turer must register with the Deparhmt in accordance with Part 107, Subpart F\nof the HMFL h addition, 5 107.502(b) indicates that no pmon may manufacture a DOT\nspecification cargo tank or CTMV unless that person is registered\n42. In accordance with tj 180.417(a)(3), may thc owner prepare a manufa~tura's\ncertificate based on specificatiofi markings that were placed on the cargo tank by a person.\nwho manufactured the C W, but was not registered with the Department?\nA2. No. Section 180.41 7(a)(3) applies to DOT specification CTMVs manuf~cttued\nbefore September 1, 1995. However, even if the C W was manufactured prior to\nSqtemba 1,1995, you may not prepare a manufacturer's certificate based on\ninformntim supplied by a person who was not authorized to manufacture the CTMV.\n43. ' May the owner ~f the CTMV create the documents that are required to be\nmaintaiaed by 4 178.345-15?\nA3. No. The owner o f the CTMV is not permitted to create thc documents identified\nin 8 178.345- 15. The docummts must be supplied to the owner by the manufacturer of\nthe CTMV. This hcludss the certification documents that display the registration\n\n<<<PAGE 8>>>\n\nnumber of the manufacturer, the Design. Certifying Engineer, and the Registered\nInspmtor. h addition, these dc~cumetlts must iaclude a certificate signed by a responsible\nofficial of the manufacturer and a Design Certifying Engineer certifying that the CTMV\nmeas the applicable specification.\nBecause the owner is unable to provide any of the required documents and because the\nperson who manufactured the CTMV was not an authorized manufacturer, the cargo tank\nmust be ctxhl'ied wder the procedures applicable to newly constructed cargo tanks. In\nthe situation described in your letter, you would be converting a non-specification CTMV\ninto a POT specification CTMV, To accomplish this, your company could b e c ~ m the\nmanufacturer of the CTMV and issue the certificates identified in 3 178.345-15. This\nwould entail registration as a cargo tank manufacturer in accordance with Part 107,\nSubpart F and performance of all, tests and inspecdons under Pm 178, Subpart J, as\napplicable to the DOT Specification 406 CTMV described in your documented QC\nprogram used to obtain your ASME Code \"W\" stamp.\nI hope this information is helpful.
