SE Washington, D.C. 20590 ttAR 1 3 2QU Mr. Rick Chewning GeoDynamics 10500 West Interstate 20 Millsap, TX 7 6066 Reference No. 12-0013R Dear Mr. Chewning: This is in response to your e-mail asking us to define the term "in transit" under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). In your letter, you describe a scenario in which you have a skid of Class 1.4 explosives, packaged, placarded, and strapped to the flatbed of a pick-up truck. You ask whether the truck may be loaded the night before delivery provided the truck and warehouse is locked. You state that the warehouse has an alarm system with code-specific security gates at the entrances. The term "in transit" is not defined in the HMR. However, for purpose of the HMR, as defined in § 171. 8, "transportation" or transport means the movement of property and loading, unloading, or storage incidental to that movement. With respect to the pick-up truck, it may be loaded the night before delivery. However, for a private motor carrier, transportation in commerce does not begin until the motor vehicle driver takes possession of the hazardous material for the purpose of transportation. Transportation continues until the driver relinquishes possession of the hazardous mate1ial at its destination and is no longer responsible for performing functions subject to the HMR (§ 17l.l(c)). In the case of a private motor carrier, hazardous materials stored temporarily at a location after the driver has taken possession of the hazardous material for the purpose of transportation is considered storage incidental to movement and is subject to the HMR (§ 171.l(c)(4)). Although no specific length of time is prescribed in the HMR, as specified in § 177 .800( d), all shipments of hazardous materials, including explosives, being transported by motor vehicle (in this case, a pick-up truck) must be transported without unnecessary or undue delay, from and including the time of the start ofloading of the hazardous materials until its final unloading at the destination. (Also, for your information, see § 172.800 for security plans and applicability.) <<>> I hope this infonnation. Please contact this office should you have additional questions. Sincerely, T.
