No. 99-0255\nOnyx Environmental Services L.L.C.\nRoxbury Business Park\n1705 Route 46 West, Unit #2\nLedgewood, NJ 07852\nDear Ms. Malone:\nThis is in response to your telephone conversation and follow up letter dated September 3, 1999, to\nDr. Richard Tarr of the Office of Hazardous Materials Exemptions and Approvals requesting\nclarification on the hazard class and transportation of forbidden materials that are stabilized or diluted\nunder the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).\nYour understanding of the provisions addressing forbidden materials per your conversation with\nDr. Tarr is correct and is further clarified. As stated in your letter, if any specifically listed, pure,\nforbidden material is stabilized or diluted to reduce or eliminate the hazards, it is then no longer\nconsidered a forbidden material. It is your responsibility to ensure it is stabilized, classed and\ntransported in accordance with the HMR. Organic peroxides, explosives, and self reactive materials\nalways require formal approval from the Associate Administrator for Hazardous Materials Safety. For\nother than these materials, no formal approval or authorization is required from DOT to dilute, stabilize,\nand transport the material. The proper shipping name \"nitrobromobenzene\" does not apply to stabilized\nand diluted \"1-bromo-3-nitrobenzene\" since it no longer meets the definition for Division 6.1. A\nsolution of 90% ethanol, 10% 1-bromo-3-nitrobenzene presents a flammability hazard, therefore, the\nproper shipping description \"Flammable liquids, n.o.s., (ethanol and nitrobromobenzene), 3, UN 1993,\nPG II\" is appropriate.\nI hope this further clarifies and answers your inquiry.\nSincerely,\nmintpells\nDelmer F.

A\nsolution of 90% ethanol, 10% 1-bromo-3-nitrobenzene (for dilution) would present a\nflammability hazard, therefore the proper shipping name Flammable liquids, n.o.s.,\n(ethanol and nitrobromobenzene) 3.1, UN1993, PG III would reflect this hazard.\nIf you have any additional comments or concerns, please feel free to contact me.\nSincerely,\nLaver Malone\nLauren Malone\nTechnical Research Specialist\nROXBURY BUSINESS PARK • 1705 ROUTE 46 WEST • UNIT #2 • LEDGEWOOD, NJ 07852\nTEL.973.448 2884 FAX 973.691.3978","truncated":false,"body_characters":3517}
