No. 13-0007\nDear Mr. Wakefield:\nThis responds to your January 2, 2013 e-mail requesting clarification of the Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 1 00-180) applicable to the reclassification and\nsegregation of certain explosive articles when transported by motor vehicle. Specifically,\nyou ask whether a transport vehicle is required to be placarded if: ( 1) it contains packages of\nUN0289, Cord, detonating, 1.4D, reclassed from UN0065, Cord, detonating, l.ID, under the\nconditions prescribed in§ 173.63(a); (2) the explosive articles are transported on the same\ntransport vehicle as other authorized and compatible Division 1.4 materials as prescribed in\n§ 177.848; (3) the aggregate gross weight of all Division 1.4 packages on the transport\nvehicle is less than 454 kg (1 001 lbs) as prescribed in § 172.504; and ( 4) any detonators and\ndetonating cord on the transport vehicle are segregated as prescribed in§ 177.835(g).\nThe answer is no, a transport vehicle containing the Division 1.4 materials you describe is\nnot required to be placarded under the HMR. Additionally, under the Federal hazmat\ntransportation law, a State or local jurisdiction could not require such a transport vehicle to\nbe placarded; however, the authorized placard may be displayed permissively on a transport\nvehicle as prescribed in§ 172.502(c).\nI trust this satisfies your inquiry. Please contact us if we can be of further assistance.\nSincerely,\nT. Glenn Foster\nChief: Regulatory Review and Reinvention Branch\nStandards and Rulemaking Division\n\n<<<PAGE 2>>>\n\nDrakeford, Carolyn (PHMSA)\nFrom:\nSent:\nTo:\nSubject:\nINFOCNTR (PHMSA)\nWednesday, January 02, 2013 2:24 PM\nDrakeford, Carolyn (PHMSA)\nFW: letter of interpretation/clarification.\nbplosive__s\n13- OD07\nHi Carolyn,\nWe received the following request for a formal letter of interpretation.\nThanks,\nVictoria\nFrom: Darren Wakefield [mailto:wakefieldblasting@gmail.com]\nSent: Wednesday, January 02, 2013 1:25PM\nTo: INFOCNTR (PHMSA)\nSubject: letter of interpretation/clarification.\nTo whom it may concern,\nI'm requesting a letter of clarification regarding the following regulations and subsequent exceptions.\nIt is my understanding according to cfr title 49 (173.63 -transport exceptions) that you CAN transport detonating\ncord UNPLACARDED as long as your hauling less than 99lbs gross weight of the item including packaging and\nthere can be no more than 6.5 grams of explosive content per 30 em of det cord. This will then allow you to\ntransport the product under UN# 0289 which in tum classifies it as division 1.4. Under cfr title 49 (172.504-\nplacarding) it states that you can haul division 1.4 items( which are included in table 2 ) as long as your hauling\nless than 1001 Lbs.\nUnder title 49 cfr (177.835- paragraph g- part 3- subpart ii) there are exceptions for hauling detonators with\ndivision 1.4 products as long as your hauling the detonators in a seperate compartment and your magazine meets\nthe requirements of IME standard 22.\n1) As long as I meet all of the forementioned requirements can I legally transport these items UNPLACARDED?\n2) If so, are there any state laws that could supercede federal DOT laws.\nSincerely,\nDarren Wakefield\nWakefield Drilling & Blasting\n1-207-583-4839\n1","truncated":false,"body_characters":3498}
