Hazardous Materials: Show Cause and Procedures for Complying With 
the UN Model Regulation 6(d) Test Criteria for Certain Explosive 
Classification Approvals

AGENCY: Pipeline and Hazardous Materials Safety Administration (PHMSA), 
DOT.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: PHMSA is issuing this notice to serve process in accordance 
with 49 CFR 105.35(a)(3) and inform all persons who currently hold 
Explosive (EX) approvals for four specific Division 1.4S explosives of 
the process necessary for maintaining or upgrading these approvals.

FOR FURTHER INFORMATION CONTACT: Ms. Harpreet Singh, Chief, Energetic 
Materials Branch, Sciences and Engineering Division, Office of 
Hazardous Materials Safety, (202) 366-4535, PHMSA, 1200 New Jersey Ave. 
SE, Washington, DC 20590.

SUPPLEMENTARY INFORMATION: 

A. Background

    The 20th Revised Edition (2017) \1\ of the United Nations 
Recommendations on the Transport of Dangerous Goods--Model Regulations 
(UN Model Regulations) was amended so that four Division 1.4S 
explosives (i.e., UN0349, UN0367, UN0384, and UN0481) must now pass an 
additional test (i.e., the UN 6(d) unconfined package test) to continue 
to maintain the 1.4S classification. This requirement was also 
implemented for international air transport in the International Civil 
Aviation Organization (ICAO) Technical Instructions for the Safe 
Transport of Dangerous Goods by Air on January 1, 2019, and for 
international vessel transport in the International Maritime Dangerous 
Goods (IMDG) Code on January 1, 2020.
---------------------------------------------------------------------------

    \1\ https://www.unece.org/trans/danger/publi/unrec/rev20/20files_e.html.
---------------------------------------------------------------------------

    On May 11, 2020, PHMSA published a final rule titled, ``Hazardous 
Materials: Harmonization with International Standards'' [HM-215O; 85 FR 
27810].\2\ As part of the HM-215O final rule, PHMSA amended the 
Hazardous Materials Regulations (HMR; 49 CFR parts 171-180) to codify 
this amendment with a mandatory compliance date of May 10, 2021.
---------------------------------------------------------------------------

    \2\ See https://www.govinfo.gov/content/pkg/FR-2020-05-11/pdf/2020-06205.pdf.
---------------------------------------------------------------------------

    PHMSA identified 2,211 EX approvals assigned to the four UN 
identification numbers (UN ID numbers) (UN0349, UN0367, UN0384, and 
UN0481) impacted by the required UN 6(d) unconfined package test. These 
2,211 EX approvals are held by approximately 145 separate holders. 
Because of the new UN 6(d) test requirement, existing approvals for the 
four affected UN ID numbers must be modified in accordance with 49 CFR 
107.713(a)(1) to reflect whether EX approval holders have had this test 
successfully performed.
    Approval holders must either show cause why their approvals should 
not be terminated or apply for a modification of their approval prior 
to the effective date to avoid termination. EX approval holders have 
until June 3, 2021, to provide a written response to PHMSA either to 
request that PHMSA modify their approval(s) or otherwise show cause as 
to why their approval(s) should not be terminated, as required by 49 
CFR 107.713(c)(1). Approvals for which PHMSA does not receive a 
modification request by June 3, 2021, are subject to termination in a 
subsequent Federal Register notice.
    PHMSA is providing the following options to current holders of an 
EX approval affected by this requirement. Affected EX approval-holders 
may:
    (1) Request that PHMSA maintain their current classification based 
on successful completion and passing of the UN 6(d) test;
    (2) Modify their EX approval to a higher classification; or
    (3) Notify PHMSA that their EX approval is no longer in use and may 
be terminated.
    Requests may be submitted to PHMSA via email at explo@dot.gov or 
the PHMSA EX Portal at https://portal.phmsa.dot.gov/PHMSAPortal2.
    This notice is primarily intended to reach EX approval holders that 
have yet to take action or that PHMSA has been unable to contact, and 
to serve as a Show Cause notice in accordance with 49 CFR 107.713(a)(1) 
and (c) for all EX approval holders who have not submitted a 
modification request. Holders of EX approvals who have yet to request a 
modification of their approval(s) are provided in Table 2. Table 2 
below contains a list of EX approval holders by company name indicated 
in their approval and associated EX approval numbers and UN ID numbers. 
This table accurately reflects the population of holders from whom 
PHMSA has yet to receive a request to modify their approval(s) or we 
have been unable to contact as of March 31, 2021.

B. Requests To Maintain 1.4S Classification

    Applicants should submit a request letter as described in 49 CFR 
107.705 to PHMSA asking to maintain their EX approval classification as 
``1.4S.'' The application should include a copy of the current EX 
approval and documentation, such as a report from a DOT-Approved 
Explosive Test Lab or Competent Authority Approval, that demonstrates 
completion and passing of the UN 6(d) test. The application will be 
evaluated, and if deemed satisfactory, the EX approval will be revised 
with an updated packaging note designating that the classification 
meets UN 6(d) test criteria.

C. Requests for Modification of EX Approval to a Higher Classification

    Applicants should submit a request letter as described in 49 CFR 
107.705 to PHMSA asking that the current 1.4S classification on their 
EX approval be voluntarily up-classed (i.e., classification changing to 
a more appropriate classification in the absence of the UN 6(d) test) 
due to the UN 6(d) test requirement. The application should include a 
current copy of the EX approval and either the original class 
recommendation lab report or the Competent Authority Approval document 
upon which the 1.4S classification was based. The application will be 
evaluated, and if deemed satisfactory, the EX approval will then be 
modified to an appropriate classification. These approvals will be 
modified consistent with the classifications noted in Table 1 below. EX 
approvals that were issued for either UN0349 or UN0481 materials may 
also require additional information to determine the most appropriate 
compatibility group for the explosive or whether there is a more 
specific proper shipping name (PSN) that should be used.

D. Termination of EX Approval

    For those affected EX approvals for which PHMSA receives no 
notification to maintain or modify the EX approval, they will be 
subject to termination effective June 3, 2021, in accordance

[[Page 23783]]

with 49 CFR 173.58(d) and 107.713(c)(2). EX approval holders may also 
voluntarily submit requests to terminate approvals that are no longer 
desired. The terminated EX approval may be reissued upon request to an 
appropriate classification as justified by testing and with a 
recommendation in accordance with 173.56 or modified to a higher 
classification.
