No. 12-0194\nDear Mr. Martin:\nThis responds to your August 31, 2012 e-mail requesting clarification of the Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 171-180) applicable to cargo tanks. Your\nquestions are paraphrased and answered as follows:\nQ 1. What are the certification, education, or experience requirements, if any, for an\nindividual who merely replaces a reliefvalve on a Department of Transportation\n(DOT) specification cargo tank that was rebuilt, tested, and calibrated by someone\nelse?\nAl. None are prescribed. Section 180.407(a)(3) indicates that anyperson who witnesses\nor performs a test or inspection specified in § 180.407 must meet the minimum\nqualifications prescribed in§ 180.409, which include registration with the Federal\nMotor Carrier Safety Administration in accordance with Part 107, Subpart F, ofthe\nHMR. Additionally, a hazmat employee who repairs, modifies, reconditions, or tests\npackagings, as qualified for use in the transportation of hazardous materials, and who\ndoes not perform any other function subject to the requirements of the HMR, is\nsubject to the General Awareness/Familiarization, Function-Specific, and Security\nAwareness training requirements prescribed in§ 172.704.\nQ2. Once a relief valve is replaced,§ 180.413(c)(1) requires thatthe valve be tested for\nleaks in accordance with§ 180.407(h)(l). Is the leakage test prescribed in\n§ 180.407(h)(l) the only method authorized to satisfy this requirement?\nA2. The answer is yes. The leakage test prescribed in § 180.407(h)(l) is the only leakage\ntest method that may be used to satisfy§ 180.413(c)(l).\n-------------------------\n\n<<<PAGE 2>>>\n\nQ3. If alternate leakage test methods are authorized to satisfy§ 180.413(c)(l), where are\nthey defined, and are they prescribed at the discretion of the cargo tank owner?\nA3. See A2 above.\nI trust this satisfies your inquiry. Please contact us ifwe can be of further assistance.\nSincerely,\nT.

The\nverbal response was that we are not required to use only the Leakage test defined in 180.407(h)(1).\nWe have a few questions concerning the replacement of relief valves on DOT -specification cargo tanks. We note that\nunder the definitions in 180.407, the replacement of a valve is not considered to be a Modification or a Repair, and there\nis no definition of \"maintenance\".\nFirst, are there any certification, education or experience requirements for individuals replacing the relief valves on DOT-\nspecification cargo tanks? If so, what are they?\nThis involves merely replacing a relief valve that has been rebuilt/tested/calibrated by someone else.\nAfter the valve has been replaced, 180.413(c)(1) clearly requires that the valve be tested for leaks. 180.413(c)(1) also\nindicates that this requirement is met when the Leakage test defined in 180.407(h )( 1) is performed, but does not seem to\nindicate that this is the only acceptable test. Are other tests allowed?\nIf other tests are allowed, are the test parameters defined, or are they at the discretion of the cargo tank owner?\nWe appreciate your quick response. Thanks.\nRandolph Martin\nDuPont Company\n4417 Lancaster Pike\nBMP22/2222\nWilmington, DE 19805\n302-992-3443\nThis communication is for use by the intended recipient and contains\ninformation that may be Privileged, confidential or copyrighted under\napplicable law.
