P.O. Box 98952 Las Vegas, NV 89193-8952 Reference No. 17-0072 Dear Mr. Stevens: This letter is in response to your July 20, 2017, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). We have paraphrased and answered your questions as follows: Q1. You ask if the proper shipping description "UN3321, Radioactive material, low specific activity (LSA-II) fissile excepted, 7" complies with the HMR when used to describe an appropriately characterized and classed material that is transported by highway. A1. The answer is yes. Section 172.101(c)(2) permits words in italics that appear as part of a proper shipping name in the Hazardous Materials Table (HMT; § 172.10i) to be included as part of the proper shipping name. However, please note the HMT entry you reference includes a hyphen between the words "fissile" and "excepted." Q2. Provided the proper shipping description in Question Q1 complies with the HMR, you ask if the words "fissile-excepted" must be added in association with or after that description, along with any other applicable entries required by § 172.203(d). A2. The answer is yes. I hope this information is helpful. Please contact us if we can be of further assistance. Sincerely, I lenno roster T. Glenn Foster Chief, Regulatory Review and Reinvention Branch Standards and Rulemaking Division <<>> Please submit this as a letter of interpretation. Please let me know if you have any questions. Thanks, Jodi From: Stevens, Lee (Navarro) [mailto:Lee. Stevens@nv.doe.gov] Sent: Thursday, July 20, 2017 11:14 AM To: PHMSA HM InfoCenter Cc: DiSanza, E. Frank (Navarro) Subject: Interpretation requested concerning requirements of 172.102(c) & 172.203(d)(6)(i) Good morning, I am requesting confirmation of my understanding of the results of my conversation with Jodi at the Hazardous Materials Information Center concerning the interactions of the requirements of 49 CFR §172.101(c)(2) and §172.203 (d)(6)(i). As we discussed, under §172.101(c)(2), the HMR allows the proper shipping name entry (from Column 2 in the HMT) for UN3321, Radioactive Material, Low Specific Activity (LSA-Il) non fissile or fissile excepted to be used on a highway shipping paper with the words "fissile excepted" as part of the proper shipping name. §172.101 Purpose and use of hazardous materials table. (2) Punctuation marks and words in italics are not part of the proper shipping name, but may be used in addition to the proper shipping name. The word "or" in italics indicates that there is a choice of terms in the sequence that may alternately be used as the proper shipping name or as part of the proper shipping name, as appropriate. For example, for the hazardous materials description "Carbon dioxide, solid or Dry ice" either "Carbon dioxide, solid" or "Dry ice" may be used as the proper shipping name; and for the hazardous materials description "Articles, pressurized pneumatic or hydraulic," either "Articles, pressurized pneumatic" or "Articles, pressurized hydraulic" may be used as the proper shipping name. Therefore a basic description of "UN3321, Radioactive Material, Low Specific Activity (LSA-II), fissile excepted, 7" would be a compliant for use on a highway shipment of an appropriately characterized/classified material. Q1: Is this correct? Furthermore, §172.203(d)(6)(i) requires the words "Fissile Excepted" to be entered as an additional description after the basic description, if applicable to the material. §172.203 Additional description requirements 1 <<>> be entered in association with (after) the basic description "UN3321, Radioactive Material, Low Specific Activity (LSA-II), fissile excepted, 7", along with any other applicable entries required by §172.203(d)?
