Reference No. 20-0039
Dear Mr. Standish:
This letter is in response to your March 10, 2020, letter requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the requirements for a quality
assurance program (QAP).
We have paraphrased and answered your questions as follows:
Q1. You ask what process(es) and standard(s) repair facilities’ QAPs need to include in order
to comply with the “critical to quality” inspection criteria being applied.
A1. The HMR does not define the term “critical to quality.” However, § 179.7 requires tank
car facilities to have a QAP approved by the Association of American Railroads (AAR).
Specifically, § 179.7(b)(5) requires that a QAP must have a description of the
manufacturing, repair, inspection, testing, and qualification or maintenance program,
including the acceptance criteria, so that an inspector can identify the characteristics of
the tank car and the elements to inspect, examine, and test at each point.
Due to the diverse nature of activities related to the qualification of a tank car for service,
PHMSA cannot qualify a specific standard or process as conforming to the performance
standard of § 179.7(b)(5) through a letter of interpretation. The determination of whether
a QAP meets the requirements of § 179.7 considers all the specific actions the tank car
facility is responsible for performing to qualify the tank car for service. In general,
acceptance criteria must include the characteristics of the tank car and the elements to
inspect, examine, and test at each point. This includes tank car fabrication and
construction materials, and service equipment intended for installation onto a tank car,
which must be inspected, examined and tested in accordance with a tank car facility’s
QAP (see § 179.7(b)(4)).

<<<PAGE 2>>>

The approval of QAPs, including this quality assurance element, is done in accordance
with the AAR’s Manual of Standards and Recommended Practices, Section J,
Specification for Quality Assurance, M-1003.
Q2. You ask whether all the activities set forth in the AAR Manual of Standards and
Recommended Practices, Section C- III, Specifications for Tank Cars, M-1002, in
Appendix B, section 3.1.6.12, are required to be performed by a tank car facility.
A2. Any person who engages in the qualification of a tank car meets the definition of a “tank
car facility” and is subject to all applicable regulations. Note that the AAR revised its
Manual of Standards and Recommended Practices, Section C-III, Specifications for Tank
Cars, M-1002, Appendix B on December 19, 2019, to align with this position as
reflected in PHMSA’s October 8, 2019, Letter of Interpretation to the Railway Supply
Institute (Reference No. 19-0117).
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
Dirk Der Kinderen
Chief, Standards Development Branch
Standards and Rulemaking Division

Subject: Request for Formal Interpretation
Mr. Kelley:
Good afternoon. Rescar Companies (Rescar) is requesting a formal letter of interpretation
regarding how the term “Critical to Quality Characteristics,” is to be interpreted and applied to
Rescar’s incoming inspection of tank car components process in its Quality Assurance
Program under 49 CFR § 179.7 (b) (5) and how PHMSA interprets the Exception to M-1002
Technical Approval Requirements in the newly adopted Appendix B, specifically the
Exception noted at 3.1.6.12.
Background and details for this request are contained in the attached letter formalizing the
request for interpretation.
Rescar thanks you for your time and consideration of this matter.
Sincerely,
Jay G Standish
