Reference No. 15-0235
Dear Mr. Anderson:
This letter is in response to your November 20, 2015 email and May 27, 2016 telephone call
requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-
180) applicable to Department of Transportation (DOT) cylinders authorized under DOT
Exemption (DOT-E) 8404. Section 173.23(e) permits these cylinders to continue to be used
provided they are marked "DOT-4L" in compliance with § 178.57 before or at the time of the
first required retest after October 1, 1984. Specifically, you state your company has acquired
20 cylinders marked with this exemption number that are not marked "DOT 4L." We have
paraphrased and answered your questions as follows:
Q1. Does § 173.23(e) require that a filled cylinder manufactured in conformance with
DOT-E 8404 be remarked for a DOT 4L welded insulated cylinder specification and
service pressure before January 1, 1986, to be continued in use?
Al.
Cylinders filled prior to their reauthorization date may remain in service until emptied
and may be transported in commerce provided all applicable HMR requirements are
refilled and offered for transportation unless it has been requalified in accordance with
met (see § 180.205(c)). An emptied cylinder due for requalification may not be
the HMR. Section 173.23(e) does not permit the requalification. of DOT-E 8404
cylinders that are not remarked DOT 4L before or on January 1, 1986. You stated that
the cylinders you found do not meet this requirement; thus, they do not comply with
the HMR and may only be authorized for transportation under the terms of a special
permit. If you decide to apply for a special permit for these cylinders, you may submit
an application to the Associate Administrator for Hazardous Materials Safety in
conformance with the requirements prescribed in 49 FR Part 107, Subpart B.
Information on the special permit application process is also available from our
website at http://www.phmsa.dot.gov/hazmat/regs/sp-a or by contacting PHMSA's
Approvals and Permits Division at (202) 366-4511.

Q2.
If a DOT-E 8404 cylinder was not remarked for compliance with the DOT 4L
specification and service pressure before January 1, 1986, must the container be
condemned?
A2.
The answer is no. A cylinder that is serviceable for transportation may be authorized
for transport under the terms of a special permit as explained in Answer Al. If,
however, the cylinder is determined to be unserviceable and unable to be restored by
repair, rebuilding, requalification, or any other procedure, then it must be condemned
(see $ 180.203 for the "condemned" definition and § 180.205(i) for cylinder
conditions that require condemnation).
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
T. Glenn Foster
Chief, Regulatory Review and Reinvention

Recently we came across a container marked DOT E-8404. 49 CFR 173.23(e) addresses containers marked DOT E-8404.
Now for the questions:
Does 49 CFR 173.23(e) require that the container must have been remarked DOT 4L and the service pressure
before January 1, 1986?
yes
• If the container was not remarked DOT 4L and the service pressure before January 1, 1986 must the container
be condemned?
Thank you for your response.
