Mechanicsville, VA 23111

Dear Mr. Hildreth:

This responds to your letter requesting clarification of the requirements regarding the transportation of propane by a non-profit organization for disaster relief under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Your questions are paraphrased and answered below:

Q1.      Are there regulations pertaining to the quantity and size of propane tanks that can be transported in a trailer?

Al.        There are no limits on the quantity and size of propane tanks that may be transported in a trailer provided the tanks comply with § 173.24, the cylinder requirements in § 173.304, or the cargo tank and portable tank requirements in § 173.3 15 of the HMR, as applicable.

Q2.      Can a 500-600 pound propane tank mounted on a utility trailer be transported?

A2.      The answer is yes, provided your propane tanks; i.e. cylinders with a water capacity ranging from 60 to 72 gallons, conform to the requirements specified in § 173.304(d). Additional requirements for transporting Class 2 (gases) by highway are found in § 177.834 and 173.840 of the HMR.

I hope this satisfies your request.
