No. 01-0166\nTaylor-Wharton\n4075 Hamilton Blvd.\nTheodore, AL 36582\nDear Mr. Richardson:\nThis is in response to your June 27, 2001 letter and subsequent phone conversations with Diane\nLa Valle of my staff concerning manufacturing changes to UN specification 1A1 drums under the\nHazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask what\nregulations apply to modifying a stock of already manufactured UN 1A1 drums by reducing the\nheight of the top skirt by four inches according to the sketches you provided. Both configurations\nhave been design qualified under the HMR.\nYou may modify your existing drums from a tested design type to a similar, but shorter, design type\nwithout the need for additional testing as long as the modification will not reduce the structural\nintegrity of the certified drum and the manner of construction for the modified drums is the same as\nfor the tested design type. In addition, drum markings must accurately reflect the modified drums..\nI hope this satisfies your request.\nSincerely,\nEdward T. Mazzullo\nDirector, Office of Hazardous\nMaterials Standards\n\n<<<PAGE 2>>>\n\n: 36/27/2802, 19:11\n33440B4507\nTW ENGINEERING\nPAGE\n01\nJohnsen\n$118.601\nTaylor-Wharton\nlestina\nHarsco\nO1-OIEAXTRANSMITTAL\n•\nTheodore, AL 36582 USA\n4075 Hamilton Bivd\nTelephone: 251.443.8680\nWeb: www.taylorwharton.com\nFax: 251. 408.4507\nTO: Mt.
