Specifically, you ask about requirements for obtaining approval of the Associate Administrator in accordance with both the HMR and International Civil Aviation Organization Technical Instructions for the Safe Transport of Dangerous Goods by Air (ICAO TI). We have paraphrased and answered your questions as follows: QI. You ask whether an approval, as defined in§ 105.5, is required for Associate Administrator authorization to transport a lithium battery with a mass exceeding 35 kg on a cargo aircraft. A 1. The answer is yes. As mentioned in your request, special provision A54 ( see § 172.102) specifies that "irrespective of the quantity limits in Column 9B of the § 172.101 table, a lithium battery, including a lithium battery packed with, or contained in, equipment that otherwise meets the applicable requirements of§ 173.185, may have a mass exceeding 35 kg if approved by the Associate Administrator prior to shipment." As defined in §§ 105.5 or 107.1, an approval includes a competent authority approval, which is issued by the Associate Administrator, the Associate Administrator's designee, or as otherwise prescribed in the HMR, to perform a function for which prior authorization by the Associate Administrator is required. Therefore, in order to transport a lithium battery with a mass exceeding 3 5 kg, an approval by the Associate Administrator is required. Furthermore, as per the definition of a competent authority approval in§§ 105.5 or 107.1, the approval may be issued as either a special permit or approval. PHMSA has begun issuing these approvals as special permits as they provide additional flexibility and allow for party status of special permit holders and potential applicants. If you have further <<>> Q2. A2. Q3. questions regarding issuance of approvals or special permits, please contact the Office of Approvals and Permits at (202) 366-4511. You ask whether an approval issued by PHMSA is required when transporting a lithium battery with a mass exceeding 35 kg on a cargo aircraft to the United States from outside the United States and authorized for transport in accordance with the ICAO TI, including an approval issued by the State of Origin. The answer is yes. United States variation US 3 from the ICAO TI states that "lithium cells or batteries including when packed with equipment or contained in equipment transported in accordance with Special Provision A99 ... may not be transported to, from, or within the United Stated aboard a passenger or cargo aircraft without the prior approval of the appropriate authority of the U.S." Therefore, when transporting a lithium battery with a mass exceeding 35 kg on a cargo aircraft to the United States from outside the United States and authorized for transport in accordance with the ICAO TI, including an approval issued by the State of Origin and special provision A99, a U.S. competent authority approval is required. You ask whether an approval issued by PHMSA is required when transporting a lit!vum battery with a mass exceeding 35 kg on a cargo aircraft in accordance with ICAO TI Special Provision A99. A3. The answer is yes. See A2. I hope this information is helpful. Please contact us if we can be of further assistance. s~;J/i7L /41;/Ifn;Jf Chief, Standards Development Standards and Rulemaking Division <<>> Dodd, Alice (PHMSA) From: Sent: To: Cc: Subject: Attachments: Kelley, Shane (PHMSA) Tuesday, April 23, 2019 4:49 PM Hazmat Interps Pfund, Duane (PHMSA); Leary, Kevin (PHMSA); Geller, Shelby (PHMSA) Fwd: Request for interpretation - UN3840 batteries exceeding 35kg on cargo interp request 35kg batts.pdf Please process as a request for interpretation.

From: Frits Wybenga Sent: Saturday, April 20, 2019 11:08 AM To: Kelley, Shane (PHMSA) Cc: Paquet, Ryan (PHMSA); Pfund, Duane (PHMSA) Subject: Request for interpretation - UN3840 batteries exceeding 35kg on cargo Hi Shane - please accept the attached request for a letter of interpretation. I believe clarification is needed with respect to PHMSA authorization of batteries in excess of 35kg on cargo. In my opinion, the regulations do not support what is being required. If I am wrong please correct me. I am finding that based on what I believe to be incorrect application, the process continues to become more complex. People need to move these batteries efficiently. The increasing complexity serves to make US industry less competitive. I believe there is a need for a better understanding for all of us (PHMSA and people on the outside) of what is actually in the regs. There are limits on the extent to which PHMSA may regulate lithium batteries by air based on the FAA authorization bill which I understand to still be applicable. In addition, the WH just issued a memo concerning nonregulatory government policy. It discourages agencies from acting on policies that are not based on regu lation. 1 <<>> Thanks - Frits Frits Wybenga Dangerous Goods Transport Consulting Inc. 15108 Red Clover Drive Rockville, MD 20853 301-929-1668 Mobile 301-356-2096 www.dg-transportation.com 2 <<>> Dangerous Goods Transport Consulting, Inc 15108 Red Clover Drive Rockville, Maryland 20853 301-929-1668 Cell 301-356-2096 f. wybenga@comcast.net April 20, 2019 Associate Administrator for Hazardous Materials Safety (Attention: Standards, PHH-I 0) Pipeline and Hazardous Materials Safety Administration U.S. Department of Transportation East Building, 2nd Floor, E23-406 1200 New Jersey A venue, SE. Washington, DC 20590-0001 Dear Mr. Kelly: I am writing to confirm my understanding of requirements for cargo air transport of a tested lithium ion battery or battery assembly (hereafter referred to as battery) in full compliance with the regulations except for a mass in excess of 35 kg. Regulatory Background Lithium ion batteries are regulated by the HMR and the !CAO Tl under the shipping name and ID number, UN3480 Lithium Ion Batteries. Transport by Air under the HMR The HMT lists UN3840 and limits the mass of lithium ion batteries on cargo aircraft to 35 kg. It further assigns special provisions A54. Special provision A54 provides for transport of batteries in excess of 35 kg if approved by the Associate Administrator. Under§ 105.5 the term "approval" is a "written authorization, including a competent authority approval, issued by the Associate Administrator, the Associate Administrator's designee, or as otherwise prescribed in the HMR, to perform a function for which prior authorization by the Assodate Administrator is required under subchapter C of this chapter (49 CFR parts 171 through 180)." Procedures for filing an application for approval are found in § 107.705. <<>> An approval is different from a "special permit" which "means a document issued by the Associate Administrator, the Associate Administrator's designee, or as otherwise prescribed in the HMR, under the authority of 49 U.S.C. 5117 permitting a person to perform a function that is not otherwise permitted under subchapter A or C of this chapter, or other regulations issued under 49 U.S.C. 5101 et seq." Procedures for filing an application for a special permit are in § 107.105. Transport under Part 171 Subchapter C Under Part 171 , Subpart C, transport of lithium ion batteries in accordance the ICAO Tl is authorized as may be limited by § 171.23 and § 171.24 There are no added limitations in these paragraphs applicable to tested and approved lithium ion batteries, including ones in excess of 35 kg. (Note: US variation 3 in the !CAO TI is only applicable to prototype batteries.) Transport under the !CAO TI The !CAO Tl also provide for transport of lithium ion batteries on cargos aircraft under UN3840 and in packing instruction 965 limit the mass of such batteries to 35 kg. Like the HMR, the !CAO TI also include a provision for batteries exceeding 35 kg, if approved by the appropriate authority of the State of Origin (see A99). The required document for authorizing transport of a battery exceeding 35 kg under the HMR. It is my understanding that an approval is needed from PHMSA to allow a battery exceeding 35 kg in that a prior authorization by the Associate Administrator is required under subchapter C, where, in this case, A54 of subchapter C sets out the required prior authorization. Since A54 makes provision for transport of batteries in excess of 35 kg, a special permit is not required in that transport of a battery in excess of 35kg is not a function that is not otherwise permitted under subchapter A or C. When transport by cargo aircraft is in accordance with the !CAO Tl for purposes of domestic or international transport under Part 171 Subpart C, where the U.S. is the State of Origin, a competent authority approval (under the ]CAO TI termed as an approved by the appropriate authority of the State of Origin) is required and an approval by PHMSA serves as that approval. Whether the document issued is an "approval" or a "special permit" is important in that different provisions apply to approvals and special permits under Part I 07. 2 <<>> Question 1: Is it correct that an approval document as defined in §105.5 is the appropriate document in the case of an Associate Administrator authorization for transport of a lithium ion battery in excess of 35 kg on a cargo aircraft? Note that while P HMSA has in the past issued approvals for batteries in excess of 35 kg, for unexplained reasons and without notice, P HMSA now employs special permits for this authorization. See for example, Special Permit number 20805 listed in P HMSA 's Special Permit Notice published in the Federal Register on April 15, 2019. The need for a document from PHMSA for transport of a battery exceeding 35 kg when transport is from outside the US to the US? For transport under the ICAO TI in accordance with Part 171 Subpart C, it is my understanding that no additional restrictions apply to the transport of lithium ion batteries exceeding 35 kg beyond compliance with the provisions of the ICAO TI. For a battery exceeding 35 kg shipped from outside the US to the US, its transport will have to have been approved by the appropriate authority of the State of Origin. Any requirement for an additional approval by the Associate Administrator in the case of foreign shipments to the US would seem to exceed the requirements of the ICAO TI as they affect lithium ion batteries and I am unaware of any provision in the HMR for such a separate approval. Question 2: Is it correct that, for a battery exceeding 35 kg transported by cargo aircraft from outside the US and authorized for transport in accordance with the ICAO Tl, including an approval issued by the State of Origin, that no further approval by PHMSA is required? The need for relief from the HMT 35kg limitation when transport is in accordance with the ICAO Tl. For transport in accordance with the ICAO TI in accordance with Part 171 Subpart C, PHMSA staff has in the past advised that a special permit is needed in the case of cargo aircraft transport of a lithium ion battery exceeding 35kg based on the HMT 35 kg restriction. PHMSA special permits authorizing batteries in excess of 35kg cite the 35kg limit in the HMT. For a shipment of a lithium ion battery consigned in accordance with the ICAO TI as provided by Part 171 Subpart C, I am unaware of a need to take the provisions of the HMT into account unless there is a relevant restriction in § 171.23 or § 171.24. Even though both the HMR and the ICAO TI include a 35kg limit and provide for relief by way of an approval, it is only the ICAO TI limitation and not the HMT limitation that needs to be addressed through an approval by the State of Origin in the case of ICAO TI transport. 3 <<>> Question 3: Is it correct that for authorized transport in accordance with the ICAO TI only an approval based on ICAO Special Provision A99 is needed? I appreciate your consideration of this request for interpretation. As our society increasingly shifts to electric vehicles employing lithium ion battery assemblies in excess of 35 kg, I am sure that you can appreciate the need for a correct understanding of the questions posed. As PHMSA is repeatedly confronted with new requests for approvals for batteries exceeding 35kg, a timely clarification would be in the best interest of PHMSA and industry which has a need to transport batteries in a rapidly developing and highly competitive and global field . Please contact me if there is any need for clarification on my questions. Sincerely, Frits Wybenga Dangerous Goods Transport Consulting, Inc. 4 - **truncated:** false - **body characters:** 13555
