Dear Mr. Latham:
This is in response to your letter requesting clarification of the applicability of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) to an electrical generator containing propane installed on commercial trucks. You state that the generator provides power to charge the truck"s batteries and power the electrical system of the truck when the truck"s engine is not running. I apologize for the delay in responding and any inconvenience it may have caused.
A fuel tank meeting the requirements in the Federal Motor Carrier Safety Regulations (FMCSR) for fuel systems and used only for supplying fuel for the operation of a motor vehicle or its auxiliary equipment is not subject to regulation under the HMR with respect to its use on the vehicle. See FMCSR requirements at 49 CFR 393.65, and 393.69 for liquefied petroleum gas systems. Such tanks must conform to all applicable marking requirements and be maintained in accordance with NFPA/ASME standards for fuel systems.
I hope this information is helpful. Please contact this office if you need additional assistance.
Sincerely,
Hattie L. Mitchell
