National Toxicology Program; National Toxicology Program (NTP), 
Board of Scientific Counselors' Meeting; Review of Draft NTP Technical 
Reports

    Pursuant to Public Law 92-463, notice is hereby given of the next 
meeting of the NTP Board of Scientific Counselors' Technical Reports 
Review Subcommittee on December 9 and 10, 1997, in the Conference 
Center, Building 101, South Campus, National Institute of Environmental 
Health Sciences (NIEHS), 111 Alexander Drive, Research Triangle Park, 
North Carolina. The meeting will begin at 1:30 p.m. on December 9, and 
at 8:30 a.m. on December 10, and is open to the public. The agenda 
topic is the peer review of draft Technical Reports of long-term 
toxicology and carcinogenesis studies from the National Toxicology 
Program. Additionally, there will be a presentation made concerning 
data obtained from transgenic mouse models on several of the chemicals 
being reviewed.
    Tentatively scheduled to be peer reviewed on December 9-10 are 
draft Technical Reports of 10 two-year studies, listed alphabetically, 
along with supporting information in the attached table. All studies 
were done using Fischer 344 rats and B6C3F1 mice. The order 
of review is given in the far right column of the table. Copies of the 
draft Reports may be obtained, as available, from: Central Data 
Management, MD E1-02, P.O. Box 12233, Research Triangle Park, NC 27709 
(919/541-3419), FAX (919/541-3687), email: [email protected].
    Public comment on any of the Technical Reports is welcome. Persons 
wanting to make a formal presentation regarding a particular Technical 
Report must notify the Executive Secretary by telephone, by FAX, by 
mail, or by email no later than December 4, 1997, and provide a written 
copy in advance of the meeting so copies can be made and distributed to 
all Subcommittee members, ad hoc expert consultants, and staff, and 
made available at the meeting for attendees. Written statements should 
supplement and may expand on the oral presentation. Oral presentations 
should be limited to no more than five minutes.
    The program would welcome receiving toxicology and carcinogenesis 
information from completed, ongoing, or planned studies by others, as 
well as current production data, human exposure information, and use 
patterns for any of the chemicals listed in this announcement. Please 
contact Central Data Management at the address given above, and they 
will relay the information to the appropriate staff scientist.
    The Executive Secretary, Dr. Larry G. Hart, P.O. Box 12233, 
Research Triangle Park, North Carolina 27709 (telephone 919/541-3971; 
FAX 919/541-0295; email [email protected]) will furnish agenda and a 
roster of Subcommittee members and expert consultants prior to the 
meeting. Summary minutes subsequent to the meeting will be available 
upon request to Central Data Management.
