D.C. 20590\nMr. Scott Meridith\nService Support Coordinator\nChemStation International\n3400 Encrete Lane\nDayton, OH 45439\nReference No. 09-0211\nDear Mr. Meridith:\nThis is in response to your letter concerning Special Permit DOT-SP 12412 issued by the\nPipeline and Hazardous Materials Safety Administration. This special permit authorizes its\nholder to discharge liquid hazardous materials from DOT Specification 57 portable tanks and\ncertain UN standard intermediate bulk containers (IBCs) while the containers remain on the\nmotor vehicle on which they were transported. You ask if two or more materials that may cause\nan unsafe condition when mixed may be loaded on the same transport vehicle if one material is\nin a UN 31H2 open-head plastic intermediate bulk container (IBC) and the other is in a UN lHl\nclosed-head plastic drum. We apologize for the delay in responding and any inconvenience this\nmay have caused.\nSpecial Permit DOT-SP 12412 authorizes compatible liquid hazardous materials to be placed in\nand discharged from a UN 31A, 31B, 31N, 31Hl, 31H2, or 31HZl IBC, or a DOT Specification\n57 portable tank without removal from the transport motor vehicle, an operation not normally\npermitted under the HMR. See § 177 .834(h). In accordance with paragraph 8.c of the special\npermit, \"UN 1778, Fluorosilicic acid (i.e., fluosilicic acid), 8 (corrosive), PG II\" and \"UN 1791,\nHypochlorite solutions, 8, PG II or III\" contained in separate IBCs may be loaded on the same\nmotor vehicle with two or more materials that could cause an unsafe condition when mixed\nprovided that: (1) no more than two IBCs are transported on the same motor vehicle; (2) each\nIBC has a capacity that does not exceed 450 gallons; (3) the materials on the vehicle are not\nunloaded at the same time; and (4) the hazardous materials on the vehicle are used for water\ntreatment only. Otherwise, paragraph 7.cA specifically prohibits packages authorized under the\nspecial permit from being loaded on the same motor vehicle with two or more materials that\nwould cause an unsafe condition if mixed. .\nI hope this satisfies your request.\nSincerely,\n(---¥~=-7\"~;-\nT.

INTERNATIONAL\nTo: Mr. Edward T Mazzullo\nDirector, Office ofHazardous Materials Standards\nU.S. DOT/PHMSA\n1200 New Jersey Avenue, SE Building, 2nd Floor\nWashington, DC 20590\nRe: DOT-SP 12412\nDear Mr. Mazzullo\nPage three of DOT -SP 12412 states that two or more materials may not be loaded on the\nsame vehicle if any mixture ofthe materials would cause an unsafe condition. My\nquestion is if it would be permissible to transport two such products on the same vehicle\nif one was in an UN 31 H2 IBC and the other in a UN 1 H 1 drum. The drums would be\npalletized setting on the rear ofthe delivery truck and delivered to the customer prior to\nopening the !BC for pumping. At no point during the delivery process would a container\nbe opened until the drums are delivered.\nIf you have any questions or concerns, please contact me at (800) 554-8265 ext. 1 148 or\nat smeridith@chemstation.com.\nSincerely,\n5riJ7(\nScott Meridith\nService Support Coordinator\nChemStation International\n3400 Encrete Lane\nDayton, OH 45439\n937-294-8265 ext.l148","truncated":false,"body_characters":3497}
