Dear Mr. Wright:
This is in response to your letter dated December 24, 1998, requesting clarification on the applicability
of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) to your harvesting operation
involving a fuel truck. Specifically, you are requesting clarification on whether your service truck
carrying a bulk fuel tank which powers the truck and is also used for offloading diesel fuel into the
harvesting equipment is required to be placarded.
It is the opinion of this office that if a fuel tank meets the requirements for all fuel systems under
§§ 393.65 and 393.69 of the Federal Motor Carrier Safety Regulations (FMCSR), including marking,
and is maintained in accordance with NFPA/ASME standards for fuel systems, and not used as a
packaging for hazardous materials, e.g., a cargo tank, then it is subject only to the FMCSR. However,
if it does not meet the FMCSR requirements for fuel systems, then the fuel tank would meet the
definition of a "cargo tank" (see § 171.8). Under the HMR, a cargo tank is subject to specification
packaging, shipping papers, marking, placarding, and emergency response information requirements.
I hope this answers your inquiry.
Sincerely,
Delm A Billio,
Delmer F. Billings

Dear Helen
I spoke with you on December 21 1998 concerning my service truck, which is used to fuel our
ling equipment in our aperation.
This truck is diesel powered and has a bulk cargo tank which powers the truck and also carries
Dies
al fuels for the combines.
Whon we spoke it was my understanding that the vehicle did not have to be placard when it
is being driven on the road.
However, did have to be placard when it was off loading the diesel fuel in to the
Harvesting equipment.
I would like a letter of interruption for my records stating this.
Sincerety
Kite sight
Kent C. Wrigtr
