Karin V. Christian, Office of the Chief Counsel, Research and Special Programs Administration (Tel. No. 202-366-4400), Room 8407, U.S. Department of Transportation, Washington, DC 20590-0001.

# SUPPLEMENTARY INFORMATION:

                    On November 16, 2000, RSPA published a notice in the                     **Federal Register**                     inviting interested parties to submit comments on an application by Boston & Maine Corporation for an administrative determination of whether Federal hazardous materials transportation law preempts the Commonwealth of Massachusetts' definitions of “hazardous materials” as applied to hazardous materials transportation. See 65 FR 69365.                

                    RSPA extended the period for commenting on the preemption determination application twice after receiving two requests from the Commonwealth of Massachusetts. Thus, RSPA extended the comment period to April 13, 2001, and the rebuttal comment period to May 29, 2001.                          ( print page 29377)    

On May 21, 2001, Boston & Maine Corporation sent a letter to RSPA requesting a two-week extension to June 12, 2001, to file rebuttal comments. In its letter, Boston & Maine Corporation states that the Commonwealth of Massachusetts has assented to the request for an extension of time. Accordingly, RSPA is extending the rebuttal comment period to June 12, 2001.

Rebuttal comments should address whether and how Massachusetts' definitions of “hazardous material” are applied and enforced by the State with respect to transportation that is subject to the HMR.

Issued in Washington, DC on May 24, 2001.

Robert A. McGuire,

Associate Administrator for Hazardous Materials Safety.
