Dear Mr. Stiger:
This responds to your letter concerning the transportation of combustible liquids to Hawaii from
the continental United States in accordance with the Hazardous Materials Regulations (HMR; 49
CFR Parts 171-180).
Your questions are in relation to the transport of hazardous materials by air. In coordinating our
response with the Federal Aviation Administration (FAA), we have learned that you are a
hazardous materials inspector employed by the FAA. While the hazardous materials regulations
(HMR) are promulgated by the Pipeline and Hazardous Materials Safety Administration
(PHMSA), they are enforced separately by each Operating Administration (including FAA). In
your official oversight role as an air-mode government inspector, you may be subject to policies,
restrictions, and guidance issued by FAA beyond any guidance PHMSA may provide you. We
recommend that you provide your questions concerning the HMR to your FAA supervisor so
they can be forwarded via the chain of command to PHMSA for consideration. Use of the chain
of command in this situation is designed to ensure that inspectors operating in a particular mode
of transport receive consistent guidance at approximately the same time.
Thank you for your interest in hazardous materials transportation safety.

Dear Mr. Mazzullo:
I am requesting a Letter of Interpretation concerning the transportation of combustible
liquids to Hawaii from the continental United States. This request is generated from
information your office provided to Mr. Jim Powell in a Letter of Interpretation dated
November 17, 2004 (Ref. No.: 04-0212).
Given the following transportation scenario:
A box of 1-liter bottles (non-bulk package) containing a liquid with a flash point of 105
degrees Fahrenheit, that is not a hazardous substance, hazardous waste, or marine
pollutant, is offered for air transportation from a shipper in Denver, Colorado, to a
recipient in Waikoloa, Hawaii. The shipment takes the following route:
1) An Integrator, who is a not an International Air Transport Association
(IATA) member, picks-up a shipment that is not declared as a hazardous
material utilizing the provision in 49 CFR, 173.150(f) and transports it, via
truck, to the Denver, Colorado, airport.
2) The shipment is sorted and placed on the Integrator's all-cargo aircraft and
flown to Portland, Oregon.
3) The shipment is sorted and consolidated with other freight in Portland,
Oregon, and loaded on a passenger-carrying aircraft (who is an IATA
member) for air transport from Portland, Oregon, to Honolulu, Hawaii.
4) The shipment is sorted in Honolulu, Hawaii, and placed on a passenger-
carrying aircraft (another IATA member) for air transport to Kona, Hawaii.
5) The shipment arrives in Kona, Hawaii, is sorted and placed on a truck for
final delivery in Walkoloa, Hawaii.

material regulated!
C) Are any of the carriers (ground or air) required to report to DOT, under 49
CFR, 171.16, if the shipment, as described above, is discovered leaking
during transit!
D) If your answer is yes to C, which carrier(s) in the transport chain would be
responsible to report the shipment to DOT?
E) Would an air carrier, who only accepts hazardous materials utilizing the
International Civil Aviation Organization's for Technical Instructions for the
Transport of Dangerous Goods (ICAO Technical Instructions), be required
to report the shipment, as described above, if it was discovered during
transit to the Federal Aviation Administration per 49 CFR, 175.31?
F) If you replaced Waikoloa, Hawaii, with remote Alaska village, Kona,
Hawaii, with Nome Alaska, and Honolulu, Hawaii, with Anchorage, Alaska,
in the scenario above; what would be your answers be to A, B, C, D, and E?
Thank you for your prompt attention to this matter.
Respectfully yours,
Donald Stiger
