Dear Mr. Bolds:
This is in response to your July 6, 2007 letter concerning the applicability of the Hazardous Materials Regulations (HMR: 49 CFR 171-180) to tank car unloading. In your letter, you present the following scenario:
You state that railroad tank cars are unloaded into fixed storage tanks at a terminal. After unloading, the tank cars are disconnected and prepared for return transit as residue cars. Tank trucks are then loaded from the fixed storage tanks. You state that this specific unloading rack operation is not a transloading operation as defined in the HMR because the tank cars are unloaded into fixed storage tanks rather than non-bulk or bulk packaging, and, therefore is not subject to the tank car unloading requirements specified in § 174.67. You ask whether your interpretation is correct.
The answer is yes. As defined in § 171.8, transloading means the transfer of a hazardous material by any person from one bulk packaging to another bulk packaging, from a bulk packaging to a non-bulk packaging, or from a non-bulk packaging to a bulk packaging for the purpose of continuing the movement of the hazardous material in commerce. The material in your scenario is being transferred from a bulk packaging to fixed storage tanks. Fixed storage tanks do not meet the definition of non-bulk or bulk packaging nor does this operation meet the definition of transloading. Therefore the rack operation you described is not generally subject to the tank car loading requirements (e.g., attendance) specified in section 174.67. However, the requirements of Section 173.31(g) would still require protection of the operation while tank cars are connected and product is being unloaded.
I hope this information is helpful.
Sincerely,
John A. Gale
