Dear Lt. Lacey,

This responds to your June 9, 2004 e-mail concerning the applicability of the Hazardous Materials Regulation (HMR), 49 CFR Parts 171-180 to US Air Force employees transporting hazardous materials, in government vehicles upon pubic highways.

In your e-mail you state that the US Air Force is requesting our written concurrence that hazardous materials transported by US Air Force military personnel on public roads for a noncommecial governmental purpose are not subject to HMR requirements.

RSPA's position concurs with the US Air Force's belief along the following general principals:

  1. The HMR do not apply to the US Air Force as a carrier unless it transports hazardous material in the furtherance of a commercial enterprise.
  2. Transportation is not in furtherance of a commerical enterprise if it is carried out by government personnel and for a government purpose. We conclude that:
  1. US Air Force military personnel are government personnel, but contractors for the US Air Force are not; and
  2. The scope of a governmental purpose is sometimes difficult to define in the abstract, but an activity likely to fall in this domain would be the transportation of liquid oxygen converters in cryogenic pressurized cylinders upon a public road as described in your e-mail.
  • The fact that transportation occurs on public roads is of no consquence since a Federal agency that transports hazardous materials for noncommercial purposes, using its own personnel, is not engaged in transportation in commerce regardless of whether the hazardous material is transported on public or private roadways.
  • The US Air Force, in performing the functions described in your e-mail using military personnel, not contractor employees, is subject to the Federal hazardous materials transportation law, 49 U.S.C. § § 5101-5127, and the HMR.
