Sec. 846. Additional powers of the Secretary

    (a) The Secretary is authorized to inspect the site of any accident, 
or fire, in which there is reason to believe that explosive materials 
were involved, in order that if any such incident has been brought about 
by accidental means, precautions may be taken to prevent similar 
accidents from occurring. In order to carry out the purpose of this 
subsection, the Secretary is authorized to enter into or upon any 
property where explosive materials have been used, are suspected of 
having been used, or have been found in an otherwise unauthorized 
location. Nothing in this chapter shall be construed as modifying or 
otherwise affecting in any way the investigative authority of any other 
Federal agency. In addition to any other investigatory authority they 
have with respect to violations of provisions of this chapter, the 
Attorney General and the Federal Bureau of Investigation, together with 
the Secretary, shall have authority to conduct investigations with 
respect to violations of subsection (d), (e), (f), (g), (h), or (i) of 
section 844 of this title.
    (b) The Secretary is authorized to establish a national repository 
of information on incidents involving arson and the suspected criminal 
misuse of explosives. All Federal agencies having information concerning 
such incidents shall report the information to the Secretary pursuant to 
such regulations as deemed necessary to carry out the provisions of this 
subsection. The repository shall also contain information on incidents 
voluntarily reported to the Secretary by State and local authorities.
