Reference No. 19-0117
Dear Mr. O'Malley:
This letter is a follow-up to our September 13, 2019, meeting with you and your members
regarding specific requirements of the Hazardous Materials Regulations (HMR; 49 CFR
Parts 171-180) applicable to rail tank car facilities. This response clarifies the
applicability of tank car facility quality assurance programs (QAP), as well as regulations
related to pre-trip inspections and internal linings and coatings. PHMSA, in conjunction
with FRA, is issuing this letter of clarification to clarify and revise previous
correspondence issued by the Department. This letter of clarification supersedes previous
letters Nos. 15-0124 and 18-0029.
Tank Car Component Manufacturers
In 2015, Salco Products asked PHMSA to clarify whether a manufacturer of components
for tank cars ( e.g., valves used for loading and unloading) would be considered a tank car
facility. In response, PHMSA issued letter No. 15-0124, stating a facility that
manufactures equipment that is attached to an opening on a tank_ car, including
components such as valves, is a tank car facility. ·
In 2018, the Railway Supply Institute (RSI) asked PHMSA a series of questions related
to PHMSA's authority to regulate the manufacturers of components of specification
packaging. PHMSA's letter No. 18-0029 affirmed letter No. 15-0124, and further stated
that a company that manufactured components for a DOT specification tank car would be
subject to the QAP requirements of§ 179.7.
· PHMSA and FRA have reviewed letters Nos. 15-0124 and 18-0029, and determined that
requiring manufacturers of tank car components to .maintain QAPs that meet the
requirements of § 179. 7 is beyond the scope of the current requirements. The
requirements of the HMR apply to manufacturers of components of DOT specification
packagings, as provided in § 171.1 ( a); however, tank car component manufacturers do

not meet the definition of a "tank car facility," because they are not making a
"representation" of the tank car's conformity as specified in § 179 .2.
PHMSA and FRA have determined that an entity that qualifies a tank car is a tank car
facility and therefore must have an approved QAP, and we will continue to hold tank car
facilities responsible for ensuring compliance of all service equipment and any other
components. Furthermore, PHMSA and FRA will continue to monitor compliance
through our standard process of inspection and enforcement.
As such, PHMSA will remove letters Nos. 15-0124 and 18-0029 from its website, and
replace them with this letter of clarification.
Pre-Trip Inspections
Any person who offers a tank car for transportation is required to conduct a pre-trip
inspection to ensure the tank car is in proper condition and safe for transportation, in
accordance with § 173 .31. Pre-trip inspections commonly identify safety issues,
including worn or unsuitable gaskets, manway bolts, fasteners, and secondary closures,
which must be addressed before the tank car can be safely offered into transportation.
On December 21, 2018, PHMSA received a letter from the American Chemistry Council
(ACC) requesting clarification. The letter asks whether facilities where tank cars are
offered into transportation meet the definition of "tank car facility" in accordance with
§ 179.2 and are therefore required to maintain a QAP that meets the requirements of
§ 179.7. The answer is no.
As indicated above, a tank car facility is an entity that qualifies a tank car. A person who
offers a hazardous material into transportation (offeror), on the other hand, is required to
perform a pre-trip inspection to ensure a tank car is in proper condition for transportation
from point of origin to destination. Offeror facilities that only perform pre-trip
inspections of a tank car are not "tank car facilities" and not subject to the QAP
requirements of § 179. 7. However,· an offeror who engages in the qualification of a tank
car meets the definition of a tank car facility and is subject to all applicable regulations.
Internal Linings and Coatings
The HMR prescribe requirements for the inspection of tank car linings in § 180.509(i).
On May 22, 2019, the ACC requested a letter of clarification on the applicability of the
inspection requirements of§ 180.509(i). Specifically, ACC asked whether internal
linings and coatings used solely to protect product purity (i.e., they play no role in
protecting the tank from corrosion) are subject to the inspection requirements
§ 180.509(i). The answer is no.

The requirements of§ 180.509(i) apply only to internal tank car linings and coatings that
are applied to protect the tank from a material that is corrosive or reactive to the tank.1 It
is the responsibility of the internal lining or coating owner to ensure that the internal
lining or coating is solely for product purity purposes.
I hope this information is helpful. Please contact us if we can be of further assistance.
