SE\nWashington, DC 20590\nPipeline and Hazardous Materials\nSafety Administration\nDEC 0 3 2a09\nMr. Joe Curtis\nVanderbilt Chemical Corporation\nMurray Division\n396 Pella Way\nMurray~ Kentucky 42071\nReference No. 05-0247R\nDear Mr. Curtis:\nThis is in further reference to our June 9~ 2006 response to your letter and telephone\nconversation with a member of my staff concerning how to classify and describe \"Zinc~\nbis(dimethylcarbamodithioato-S,S')\" and waste code \"K161,\" which are each listed by the\nEnvironmental Protection Agency (EPA) as a hazardous substance under 40 CFR 302.4\nbut not listed as a hazardous substance under § 172.10 I, Appendix A, of the U.S.\nDepartment of Transportation's Hazardous Materials Regulations (HMR; 49 CFR Parts\n171-180). In this letter, we are clarifying the acceptable shipping descriptions and\ncorrecting a referenced special provision.\nYou state your company manufactures zinc, bis (dimethy lcarbamodithioato-S,S') in pure\nform as a Division 6.1 (toxic) PG I material. This material is combined in various\nproportions with other ingredients to produce other Division 6.1, PG II or PG III, or Class\n9 (miscellaneous), PG III materials. A \"KI61\" waste is generated from manufacturing\nthese and other materials in the same chemical family. The EPA regulations in 40 CFR\n302.4 currently list both zinc, bis (dimethylcarbamodithioato-S,S') and the K161 waste\nmaterials as having a reportable quantity of 1 pound (0.454 kg). You state your company's\nproducts containing these materials will exceed their EPA reportable quantity when in\ntransit, and ask if you may describe them as follows:\nRQ, Toxic, solid, inorganic, n.o.s. (zinc, bis (dimethylcarbamodithioato-S~S'», 6.1,\nUN 2811, PG I;\nRQ, Pesticide, solid, toxic, n.o.s., (zinc, bis (dimethylcarbamodithioato-S,S'», 6.1,\nUN 2811, PG I; and\nRQ, Environmentally hazardous substances, solid, n.o.s., (zinc, bis\n(dimethylcarbamodithioato- S,S'», 9, UN 3077, PG III.\n\n<<<PAGE 2>>>\n\nIf the above proper shipping descriptions correspond with the appropriate hazard class and\nPacking Group of the materials, the descriptions can be used but without the \"RQ\"\ndesignation. Section 172.203(c)(2) of the HMR restricts the use of the \"RQ\" designation\nto hazardous substances defined in § 171.8 and listed under § 172.101, Appendix A. Solid\nmaterials containing K161 waste that are subject to the EPA's hazardous waste manifest\nrequirement specified in 40 CFR Part 262, do not meet the definition of any other hazard\nclass under the HMR, and are not a hazardous substance or marine pollutant may be\ndescribed as \"NA 3077, Hazardous waste, solid, n.o.s. (KI61), 9, PG III,\" or \"UN 3077,\nWaste Environmentally hazardous substances, solid, n.o.s. (KI61), 9, PG III. In addition,\nthe latter description may be used for international transportation. Also see Special\nProvision 146 in § 172.102. Additional information about these materials may be entered\non the shipping paper provided the information is not inconsistent with the required\nshipping description. See §§ 172.201(a)(4)and 172.202.\nI hope this satisfies your request.\nsince~\ni~ ­ Hattie L.

Some of these products-8Fe-defined as hazardous materials\npursuant te> Title 49 Parts 171 -180 (I.e., the HMR). In addition, some of these\nchemicals are, or contain, CERCLA Hazardous Substances pursuant to 40 CFR 302.4.\nThis letter discusses at least one discrepancy between 49 CFR 172.101 Appendix A and\n40 CFR 302.4 and requests your regulatory guidance.\nThe followi.ng chemical compound is one such discrepancy:\nCASRN - 137-30-4\nTechnical Name - Zinc, bis(dimethylcarbamodithioato-S,S')CERCLA\nSynonym - ZIRAM\nCommercial synonyms - zinc dimethyldithiocarbamate. methyl zjmate\nCERCLA RQ - 1 pound (statutory level: original listing c. 1989)\nThis compound is listed in 40 CFR 302.4 but not in 49 CFR 172.101 Appendix A. In\naddition, thE~ K161 waste code (which is related to the manufacture of this and other\nmembers of the same chemical family) became effective in 1995 but has not, to our\nknowtedge, been listed in Appendix A.\nVanderbilt called the DOT Hotline to discuss these particular regulatory inconsistencies,\nand although there was some surprise, the DOT Hotline representative stated that only\nthe compou.nds listed in Appendix A were regulated by the HMR for the purpose of\nCERCLA. She said, in effect, that neither the presence of this compound in 302.4 nor\nthe discrepancy between Appendix A and 302.4 had any bearing on the task of properly\nclassifying the material or on the use of the \"RO\" warning in association with the proper\nshipping des:cription.\n\n<<<PAGE 4>>>\n\nT~049 P. 0031001 HaD\n+270 m mz\nOct~04~20Q5 03:45pm Fram-VANBDERBI~T CHElIIlCAl\n............. ,~ IIC: AUMINISTRATOR FOR HAZARDOUS MATERIALS SAFETY\nJUNE 2:l. 200S\nPAGE 2\nThis seems inconsistent with the legislative history of CERCl.A and the inclusion of\ntransponation in the realm of potential for the release of hazardous substances in the\nenvironment. We believe the two fists should be identical.\nSignific~'nc8 to Vanderbilt\nVanderbilt manufactures this compound in its pure form; and can custom blend it in\nvarious concentrations with other ingredients to suit specific end uses. Based on its\ninhalation toxicity (LC&o) concentration of 0.08 mgll and its end use, Vanderbilt classifies\nthe pure form as either:\nRei, TOXIC SOUD, ORGANIC, NOS (ZINC, BIS(OIMETHYLCARBAMODITHIOATcrS,S')-),\n6:1, UN2811, PC; I (when sold as a non-pesticide)\nor\nROt PeSTICIDE, SOLID, TOXIC, NOS (ZINC, BIS(OIMETHYLCARBAMOOITHIOATO-S,S').),\n6.1, UN2811, PG I (when sold as a pesticide)\nBased on the Hotline representative's interpretation. we should omit the term \"RO\" from\nthese proper shipping descriptions.\nIn addition to offering this compound as a pure commercial chemical. Vanderbilt could\nblend it with one or more other ingredients in various proportions. It is easy to conceive\nof a blend or mixture whose LCso was Significantly increased thus lowering the packing\ngroup to PG II or PG III. It is even conceivable to raise the LC60 of a blend such that it\nwas no 10n'ler classified as a Division 6.1 Toxic. In yet another case, Vanderbilt might\nadd a procE!ssing aid to the compound or to one of the blends such that it was no longer\nrespirable. In these cases, the inhalation toxicity issue would be eliminated and the\nmixture would no longer be a hazardous material pursuant to the HMR. Nevertheless, in\neach of the!:e scenarios, the resulting product could (and probably would) still contain\nmore than a reportable quantity of a CERCLA hazardous substance in a single package.\nFor that reason, Vanderbilt believes that a dilute or non-respirable mixture (i.e., one that\ncan not be claSSified as Division 6.1 - Toxic) should be classified as Class 9Miscellaneous\nbased on the CERCLA issue. For example:\nRO, ENVIRONMENTALLY HAZARDOUS SUBSTANCE, SOLID. NOS (ZINC,\nBIS(DIMETHYLCARBAMODITH10AT~S.S·)-), 9, UN3077. PG III\nNevertheless, the HMR specifically prevents us from describing, marking and labeling\nthis material as a hazardous material (e.g•• 49 CFR 171.2 (f). 172.202 (e). 172.303 (a)\nand 172.404 (a) - see Exhibit 3). Vanderbilt is in a dilemma over this CERCLA RQ\nissue. On one hand, we feel a duty to inform transporters that they are handling a RQ\nof a CERCLA hazardous substance. On the other hand. we are prohibited from\nviolating the HMR.\nVanderbilt reC;'uests your guidance to resolVe this dilemma. To assist you with that taSk,\nwe have duplicated some relevant passages of the HMR in the enclosed exhibits.\nThank you for conSidering our situation. We look forward to hearing from you on this\nvexing issue.
