S. Department of Transportation\nOffice of Hazardous Materials Standards Pipeline and Hazardous Materials Safety\nAdministration\n1200 New Jersey Avenue, SE\nWashington, DC 20590-0001\nAttn: PH-10, US Department of Transportation, East Building\nRE: Changes to the Hazardous Materials Table for N-Aminoethylpiperazine Class\n8, UN 2815, PGIII per 49 CFR 172.101\nDear Sir or Madam:\nHuntsman Corporation is requesting from the Associate Administrator for Hazardous\nMaterials Safety a re-evaluation of the transport classification for UN 2815\nN-Aminoethylpiperazine, from Class 8, PGIII to Class 8 (6.1), PGII.\nDue to the recent availability of summarized toxicity testing data performed for the EU\nREACH legislation, it has come to Huntsman's attention that N-Aminoethylpiperazine\n(AEP), currently classified and listed in the Hazardous Material Table as a dermal\ncorrosive, should also have the subsidiary risk of being dermally toxic, as well. In\naddition, animal data suggests that the Packing Group designation for AEP should be a\nPacking Group II.\nThe toxicity testing data that requires the reclassification of AEP is summarized in the\nIUCLID dossier for AEP which has been compiled by the AEP REACH Consortium. The\ndata indicate:\n• The dermal toxicity of AEP is given as 866 mg/kg. This toxicity value\ncorresponds to a Dermal Toxic, Packing Group III. The data are summarized in\nAttachments 1 and 2.\n• The dermal corrosivity of AEP is described in the IUCLID dossier as ..... meets the\ncriteria for classification as Corrosive, sub category 1 B according to the GHS\ncriteria, since necrosis was seen at the 20 minute time point rather than the 3\nminute time point.\" This description would correspond to a transport Packing\nGroup II. The data are summarized in Attachment 3.\nBased on knowledge of this information, Huntsman is compelled to petition for a change\nin the current transport classification for AEP listed in the Hazardous Material Table 49\nCFR 172.101 from the current classification of \"UN 2815 N-Aminoethyl piperazine Class\n8, PGIII\" to \"UN2815 N-Aminoethyl piperazine Class 8 (6.1), PGII.\"\n8600 Gosling Road, The Woodlands, Texas 77381\nTel.: 1·281·719·7400 Fax.: 1·281-719·7500 www.huntsman.com\n\n<<<PAGE 9>>>\n\nPH-lO,USDOT\nPage 2\nSeptember 12, 2011\nIf I can provide any additional information or assistance, please call (281) 719 3017 or\nMr. Mike Stillwell at (281) 719-3027\nRegards,\nr:\nRaymond pciak d .\nManager, Product Safety\nMike Stillwell\nTransportation Safety Lead,\nRail Security Coordinator\nAttachments (3)","truncated":false,"body_characters":16858}
