Dear Mr. Freiler:

This is in response to your letter requesting clarification of the venting requirements for DOT 407 and DOT 412 tanks under the Hazardous Materials Regulations (HMR.: 49 CFR Parts 171-180). Your questions are paraphased and answered below:

Q1. Does the HMR require American Society Mechanical Engineers (ASME) ""if' stamped
pressure relief devices on DOT 407 or DOT 412 cargo tank motor vehicles?

A1. The answer is no. The intent of the HMR is not to require ASME "Y" stamped pressure relief devices on DOT 407 or DOT 412 cargo tanks. The provisions specified in § 178.345-10 are the applicable requirements for pressure relief devices used on a DOT 407 or DOT 412 cargo tank. These provisions do not preclude use of pressure relief devices certified to the ASME.

Q2. Does the HMR require an AS:ME pressure relief device in addition to the devices specified in 178.345-10?

A2. The answer is no. Section 178.345-10 does not require the use of an AS:ME "V" stamped pressure relief device in addition to the devices specified in the HMR.

I hope this information is helpful. Please contact this office if you require additional assistance.

Sincerely,
