Reference No. 19-0132

Dear Mr. Bower:

This letter is in response to your November 18, 2019, letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171–180) applicable to testing requirements for packages of Class 7 (radioactive) materials. You explain that it is not possible or practicable to assess the free drop test specified in § 173.465(c) in certain orientations of your Type A package due to its size and securement to the trailer during transportation. You note that the only possibility of impact to the top surface or lid of the package is if the entire package falls off the trailer, which you believe would be considered an accident condition. Specifically, you ask whether it is necessary to assess the free drop test specified for Type A packages in § 173.465(c) in certain packaging orientations that are not likely to occur under normal conditions of transport.

The answer is yes. Testing, or other demonstration of compliance in accordance with § 173.461(a), must be done to prove the package meets the requirements of §§ 173.412 and 173.465 regardless of whether you believe the package orientations are impossible or not likely to occur under normal conditions of transport.

If you are unable to demonstrate compliance with the testing requirements, you may apply for a special permit by submitting an application to the Associate Administrator for Hazardous Materials Safety in conformance with the requirements prescribed in 49 CFR Part 107, Subpart B. You may obtain information on the special permit application process from our website at https://www.phmsa.dot.gov/approvals-and-permits/hazmat/hazardous-materials-approvals-and-permits-overview, or by calling PHMSA's Approvals and Permits Division at (202) 366-4511.

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

Sincerely,

T. Glenn Foster
