Dear Mr. Heylmun:
This responds to your letter requesting clarification of the marking exception for petroleum
distillate fuels in § 172.336 under the Hazardous Materials Regulations (HMR; 49 CFR Parts
171-180). You reference an April 24, 2001 clarification letter, Reference No. 01-0082, and ask
whether a cargo tank motor vehicle containing denatured ethanol (95% ethanol and 5% gasoline)
is eligible for the marking exceptions in § 172.336(c)(4) and (5). I apologize for the delay and
any inconvenience it may have caused.
Under § 173.22, it is the shipper's responsibility to properly classify a hazardous material and
assign it a proper shipping name from the Hazardous Materials Table (HMT). For a material not
specifically identified by name in the HMT, the HMR require that the material be described by
the shipping name that "most appropriately" describes the material. Based on the information
provided, it is our opinion that the appropriate shipping description for your mixture of 95%
ethanol and 5% gasoline is "Flammable liquid, n.o.s. (Ethanol, Gasoline)". The high percentage
of alcohol in this mixture makes it ineligible as a petroleum distillate. Therefore, the cargo tank
does not qualify for the marking exceptions in § 172.336(c)(4) and (5).
Also, for your information, we proposed to reinstate the proper shipping name "Denatured
alcohol" in a notice of proposed rulemaking published August 12, 2004 (Docket No. RSPA-04-
18683 (HM-218C), 69 FR 49846). Additionally, we proposed to add new special provision 172
for both "Denature alcohol, NA 1987" and "Alcohols, n.o.s., UN 1987" to allow solutions of
alcohol and petroleum products to be described as either "Denature alcohol" or "Alcohols,
n.o.s.", provided the solution contains no more than 5% petroleum products.
I trust this satisfies your request.
Sincerely,
Hithe a mithe ll

It is my understanding that petroleum distillates are separated from crude oil by
distillation. Ethyl alcohol is obtained from the fermentation of grains and is not derived
trom petroleum distillation. Ethyl alcohol has some properties dissimilar to most DOT
class 3 petroleum distillates, such as being water-miscible.
Gasohol is specifically named in the regulations found ib § 172.336 (c) (4) and (5)
