Dear Mr. Glass:

This is in response to your June 16, 2008 letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if the intent of § 180.417(c) is to require each motor carrier operating a specification MC330 or MC331 cargo tank to make a written report if the cargo tank does not have manholes.

The answer is yes. Section 180.417(c)(3) states that after completion of the pressure test specified in § 180.407(g)(3), each person who operates an MC330 or MC331 cargo tank in any service that may cause stress corrosion cracking must make a report containing the information specified in § 180.417(c). The testing requirements in § 180.407(g)(3) do not apply to cargo tanks that do not have manholes; however, that does not except the motor carrier from the requirement to generate a report in accordance with § 180.417(c)(3).

I hope this answers your inquiry.
