    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 October 30, 1998, 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 9:00 a.m. on October 30, 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.
        Tentatively scheduled to be peer reviewed on October 30 are draft 
    Technical Reports of five two-year studies, listed alphabetically, 
    along with supporting information in the attached table. The draft 
    Report on triethanolamine had been peer reviewed previously but is 
    being returned for rereview as this was the first study in which 
    infection of B6C3F1 mice with Halicobacter hepaticus was 
    discovered. 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. By September 30, 1998, full copies of these draft 
    reports will be available for free on the Internet for public review 
    and comment through the Environmental Health Information Service (EHIS) 
    at http://ehis.niehs.nih.gov. Printed copies can 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

    Report must notify the Executive Secretary by telephone at 919/541-
    3971, by FAX at 919/541-0295, by mail, or by email at

    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 will furnish agenda and a 
    roster of Subcommittee members prior to the meeting. Summary minutes
