SE\nWashington, DC 20590\nMs. Ernest Conwell\nNSROC Program Office\nP.O. Box 99\nBuilding M16 Room 107\nNASA Wallops Flight Facility\nWallops Island, Virginia 23337\nRef. No. 08-0234\nDear Mr. Conwell:\nThis responds to your September, 23 2008 letter requesting clarification of the Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 17 1 - 180). Specifically, you ask if a rocket\nmotor containing fuel comprised of 38.6% (.05 ppm) Nitroglycerin meets the definition of a\n\"hazardous substance\" under the HMR. The referenced concentration in the rocket motor\nequals approximately 700 pounds of nitroglycerin.\nThe answer is yes. A Hazardous substance is defined in 5 171.8 as a material, including its\nmixtures and solutions, that is listed in Appendix A to 5 172.10 1, and is in a quantity, in one\npackage, that equals or exceeds the reportable quantity (RQ) for the material listed in\nAppendix A. Nitroglycerin is listed in Appendix A to 5 172.101 with a reportable quantity of\n10 pounds. The concentration of Nitroglycerin in the rocket motor exceeds the reportable\nquantity in one package (700 pounds of Nitroglycerin in the rocket motor). Therefore, the\nrocket motor meets the definition of a hazardous substance.\nI hope this information is helpful. Please contact us if you require additional assistance.\nSincerely,\nSusan Gorsky Y\nActing Chief, Standards Development\nOfice of Hazardous Materials Standards\n\n<<>>\n\nE i c h e n h b $ 172- 101\nPage 1 of 2\nDrakeford, Carolyn cPHMSA>\nFrom: INFOCNTR \nSent: Tuesday, September 23,2008 8:31 AM\nTo: Drakeford, Carolyn \nSubject: FW: Request for Clarification on Hazardous Substance\nAttachments: UN0280 MSDS.pdf\nFrom: Cornwell Ernest [mailto:Cornwell-Ernest@nsroc.net]\nSent: Monday, September 22, 2008 4:00 PM\nTo: INFOCNTR \nSubject: Request for Clarification on Hazardous Substance\nErnest R.
