Ref. No. 10-0108

Dear Mr. Hamer:

This responds to your May 5, 2010 request for clarification on the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask whether a local municipality may apply local zoning codes, fire codes and building codes at a facility where hazardous materials are parked or stored during transportation, regardless of the duration of that parking or storage.

As explained in § 171.1(f) of the HMR, a facility at which functions regulated under the HMR are performed may be subject to applicable laws and regulations of state and local governments. However, a requirement of a state, local, or tribal government that conflicts with requirements in the HMR is preempted, unless otherwise authorized by another Federal statute or the Department of Transportation issues a waiver of preemption. The Pipeline and Hazardous Materials Administration makes preemption determinations applicable to specific non-Federal requirements on a case-by-case basis. The procedures for DOT to make administrative determinations of preemption are set forth in subpart C of part 107.

I hope this answers your inquiry. For your information, it may be helpful to attend the next Hazardous Materials Multimodal Seminar being held in Milwaukee August 10-11, 2010.

Information on the Hazardous Materials Multimodal Seminar in Milwaukee can be found on our website at If you need further assistance, please contact this Office.
