FACTS: National Tank Truck Carriers, Inc. (NTTC) has requested
follow-up interpretation
to Int. No. 88-1-RSPA concerning persons
responsible as
"offerors" (or "shippers") under regulations
issued pursuant to the Hazardous Materials Transportation Act
(HMTA) •
The essence of Int. 88-1-RSPA is as follows:
Any person who performs, attempts to perform,
or, under the circumstances involved, is
contractually or otherwise responsible to

Accepting that premise and recognizing that answers to detailed
hypothetical questions may not be appropriate or applicable to
actual cases occurring in the future, NTTC nevertheless sets
a series of hypothetical fact patterns and requests answers

Many of NTT's questions seem to assume erroneously that there is
only one offeror in any given
fact situation.
In actuality there
may be one or more offerors, jointly and severally responsible
dapending upon
for compliance with the HMR, in any transportation scenario--
the details of that scenario.
INTERPRETATION: NT's hypothetical fact patterns and related
questions are set forth below,
the answer of the Research and Special Programs Administration.

would be performing offeror functions and be

Also, Company Z is
a carrier and may not accept for
transportation or transport hazardous materials without
complying with numerous HMR provisions applicable to
those functions (e.g., §§ 171.2 and 177.817).

FACT PATTERN #2
products which are considered "flammable"
Company A is engaged in the production and marketing of petroleum
and "combustible"
under
the Hazardous Materials Transportation Act.
In order to
facilitate distribution of these products, Company
A operates
several facilities, the primary function of which is to transfer
these products from its own
production and/or storage facilities
into tank motor vehicles, owned by Company I, for subsequent
distribution to retail outlets owned or otherwise controlled by
Company A.
Company Zis a motor common carrier.
Company Z's
trucks are loaded at Company A's
"facilities" and transport the
product to the "retail outlets".
By prior contractual agreement, Company A agrees to permit
Company Z to load its trucks
(at Company A's "facilities")
24 hours a day with no representative of Company A in attendance
during the loading operations.
Access to Company A's facilities
is accomplished by keys and/or electro-mechanical devices

Answer--
Company A is an offeror. More information would be
required concerning Company M's
undertaking to "arrange

in order to determine to what
extent, if any, Company M is an offeror.

is contractually or otherwise responsible to perform

"offeror") if the prior

Answer--

Assuming that this question refers to Fact Pattern #3,
which to determine that Company M is an offeror.
ADDITIONAL QUESTION B
Would there be any change in the determination of "shipper" (or
"offeror") if the prior
agreement between Companies A and M
stipulated that ownership or title to the product transferred at
the time of loading (or transfer)" into cargo tanks (regardless
of ownership of the cargo tanks)?

<<<PAGE 7>>>

Answer--
Again assuming that this question refers to Fact
Pattern #3, Company A remains
an offeror. However,
Company M has not become an offeror solely by virtue of
its acquisition of ownership of the hazardous materials
at the time of loading or transfer into cargo tanks --
a time
later than that hypothesized in Fact Pattern #3.
