Dear Mr. Calonge:
This responds to your July 17, 2013 request for clarification of the requirements for the
repair, modification, stretching, rebarrelling or mounting of specification cargo tanks under
the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask
for clarification of the term "work" as it is used in § 180.413( d)(2).
Your questions are paraphrased and answered as follows:
Ql. How does PHMSA define the term "work" as used in§ 180.413(d)(2)?
Al. The HMR does not define the term "work." As used in§ 180.413(d)(2), the
term "work'' refers to functions performed to modify, stretch, or rebarrel a cargo tank
motor vehicle.
Q2. If a part of a cargo tank motor vehicle is modified in accordance with
§ 180.413( d)(2), does the entire cargo tank motor vehicle have to comply with the
applicable specification?
A2. Yes. The cargo tank motor vehicle must comply with the applicable
specification. Pursuant to § 180.413( d)(2), all new material and equipment affected
by modification, stretching, or rebarrelling must meet the requirements of the
specification in effect at the time such modification, stretching, or rebarrelling is
performed, and the structural integrity requirements described in§§ 178.337-3,
178.338-3, and 178.345-3.
I hope this answers your inquiry. If you need additional assistance, please call this office at
(202) 366-8553.
Sincerely,
Robert Benedict
