Steinweg, Inc. concerning 171.22, 171.23, 171.25, 172.101, 172.102. ## Document text <<>> U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration 1200 New Jersey Avenue, SE Washington, DC 20590 AUG 2 6 2019 John Moors C. Steinweg, Inc. 1201 Wallace Street Baltimore, MD 21230 Reference No. 19-0072 Dear Mr. Moors: This letter is in response to your January 29, 2019, letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to packaging requirements for "UN1408, Ferrosilicon, 4.3 (6.1), PG III." Specifically, you note that the § 172.101 Hazardous Material Table (HMT) entry for UN1408 has IP Code IP7 (IP7) assigned to it in Column (7). You additionally note that the text of IP7 in § 172.102( c )( 4) does not list UN 1408 as an authorized material. We have paraphrased and answered your questions as follows: Q 1. You ask whether the addition of IP7 in Column (7) of the HMT for UN 1408 without the corresponding reference to UN 1408 in the text of IP7 in § 1 72 .102( c )( 4) was an oversight. Al. The answer is yes. In the notice of proposed rulemaking (NPRM) for HM-215G (69 FR 34724; 6/22/2004), RSPA (PHMSA's predecessor agency) proposed to add Special Provision "IP7'' to UN1408 to align with the International Maritime Dangerous Goods (IMDG) Code. However, we failed to make the corresponding edit to the description of IP7. We received no comments on the proposal in the NPRM and adopted it as proposed in the HM-215G final rule (69 FR 76044; 12/20/2004). This was not our intent and we will address this as an editorial correction in a future rulemaking. Q2. You ask whether IBCs are required to meet IBC performance testing requirements when used to transport UN1408 into the United States. A2. The answer is no; for shipments in compliance with the IMDG Code. Provided all or part of the transportation is by vessel, the HMR authorizes compliance with the requirements of the IMDG Code, provided the applicable requirements of§§ 171.22, 171.23 and 171.25 are met. As you correctly note in your request, the IMDG Code packing instructions for this material do not require that IBCs meet performance testing requirements. Therefore, provided all or part of the transportation (i.e., until the material <<>> is delivered to its final destination indicated on a shipping paper) is by vessel, and the shipment is in compliance with applicable IMDG Code requirements, IBCs used to transport UN1408 are not required to meet performance testing requirements. I hope this information is helpful. Please contact us if we can be of further assistance. ren Chief, Standards Development Branch Standards and Rulemaking Division <<>> Dodd, Alice (PHMSA) From: Sent: To: Subject: Attachments: Kelley, Shane (PHMSA) Thursday, June 06, 2019 1:39 PM Hazmat Interps FW: FerroSilicon Packaging requirements according to CFR 49 LETTER TO DOT REGARDING FERROSILICON PACKAGING 20190129.docx Alice and lkeya - Is this letter already in our system?

Regarding Ferro Silicon UN 1408 in CFR49 par 172. IO I under special provision the refer to par. 172.102 IP7, however under this special provision the ID # 1408 is NOT specifically mentioned. Why would the provision "!PT' be mentioned in "par. 172.10 I if it is not applicable. In other words, according to this special provision "IP7'' one would expect that for Ferrosilicon Class 4.3 UN 1408, IBCs are not required to meet the !BC performance tests specified in part 178, subpart N, of this subchapter.
