Reference No. 19-0094

Dear Mr. Sech:

This letter is in response to your July 22, 2019, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the inspection and testing requirements for tank car internal linings and coatings.

We have paraphrased and answered your questions as follows:

Q1. You ask whether the tank car owner or the internal lining/coating owner must maintain at its principal place of business a written procedure for collecting and documenting the performance of the coating or lining applied within the tank car for its service life, in accordance with § 180.509(i)(2).

A1. The requirement applies to the internal lining/coating owner.

Q2. You note that § 180.509(i)(3) states that the owner of the internal lining/coating is only required to provide the test method and acceptance criteria to the tank car owner and person responsible for the qualification of that internal lining/coating. You ask why the frequency of inspection was not included and whether the internal lining/coating owner is responsible for providing the full qualification and maintenance plan to the tank car owner or person responsible for qualification and maintenance of the internal lining/coating.

A2. Section 180.509(i)(3) is specific to persons performing inspection and testing of the internal lining/coating and the criteria therein. The requirement ensures that the tank car facility performing the test and inspection of the internal lining/coating is doing so in accordance with the internal lining/coating owner's determined requirements for service life, inspection and testing requirements.

Q3. You ask whether the requirement in § 180.511(e) applies to the tank car owner or the internal lining/coating owner.

A3. The requirement applies to the internal lining/coating owner.

Q4. You ask who is required to audit the person responsible for the qualification of the internal lining/coating.

A4. In accordance with § 180.509(a), each tank car owner must ensure that a tank car facility evaluates each item according to the acceptable results of inspections and test specified in § 180.511. Section 180.511 includes inspection and testing requirements for an internal lining/coating, if applicable. Therefore, a tank car owner must ensure that a tank car facility is performing the inspection and test requirements specified by the internal lining/coating owner.

I hope this information is helpful. Please contact us if we can be of further assistance.
