Dear Mr. Lloyd:

This responds to your request for clarification of an amendment to the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) adopted under Docket HM-223 (final rule published October 30, 2003; 68 FR 61905).  Your question concerns the applicability of revised § 174.67 to tank car unloading and transloading operations, Please accept my apology for the delay in responding.

Your understanding is correct.  The entire § 174.67, as revised in the HM-223 final rule, applies to transloading operations.  Effective October 1, 2004, rail tank car unloading operations performed by consignees after delivery of the rail car are not subject to regulation under the HMR.  We plan to issue a correction document later this year to clarify the applicability of  § 174.67.

I hope this information is helpful.  Please let me know if you have additional questions.
