Dear Mr. McIntyre:
This responds to your May 4, 2010 letter and telephone conversation with a member of my staff regarding the requirements for unloading hazardous materials from rail tank cars under the Hazardous Materials Regulations (HMR; 49 CFR parts 171-180). Specifically, you ask whether the electronic monitoring system you describe in your letter would be adequate to meet the requirements of § 174.67(i) and electronic rail car unloading monitoring outlined in a formal interpretation of the regulations, 87-4-RSPA. The unloading process monitored by the system you described in your letter occurs after the rail tank car has been delivered to the consignee.
The requirements in § 174.67 apply to transloading operations only. Transloading is the transfer of a hazardous material 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 (see § 171.8).
The requirements in § 174.67 do not apply to rail tank car unloading operations performed by consignee personnel after delivery of the tank car. However, the general requirements in § 173.31 for transporting hazardous materials in tank cars, including tank car loading and unloading requirements apply even when those operations are conducted by consignee personnel.
I hope this answers your inquiry. If you have further questions, please do not hesitate to contact this office.
Sincerely,
Charles E. Betts
Chief, Standards Development
