No. 02-0299 70 Cantiague Rock Road Hicksville, New York 11801 Dear Ms. Paul: This responds to your recent letter concerning requirements for shipping regulated medical waste under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask about requirements related to shipping waste material, including bone and tooth fragments and amalgam and silver filling, generated by dentists' offices. Your letter describes a device for transporting dental wastes for processing and disposal. You note that the contents of the device are treated with a disinfectant solution before the device is sealed. Medical waste that has been treated or disinfected so as to neutralize or inactivate any infectious material is not regulated under the HMR (see § 173.134(b)(8)). If the waste amalgam generated from a dentist's office contains mercury, it may be regulated as a hazardous substance under the HMR. A hazardous substance is a material, including its mixtures and solutions, that is listed in Appendix A to § 172.101 and is in a quantity in one package that equals or exceeds the reportable quantity (RQ) listed in Appendix A. The RQ for mercury is 1 pound. Thus, if your device contains 1 pound or more of mercury, then it must be transported in accordance with the HMR requirements applicable to hazardous substances. I hope this information is helpful. If you have further questions, please do not hesitate to contact this office. Sincerely, band 7. Margallo Edward T.
