National Toxicology Program (NTP) Board of Scientific Counselors' 
Meetings; Announcement of NTP Draft Technical Reports Projected for 
Public Review From December 1996 Through Fall 1998; Request for Public 
Input

    To earlier inform the public and encourage interested parties to 
comment or obtain information on projected long-term toxicology and 
carcinogenesis studies prior to public peer review, the National 
Toxicology Program (NTP) again publishes in the Federal Register a 
current listing of draft Technical Reports projected for evaluation by 
the NTP Board of Scientific Counselors' Technical Reports Review 
Subcommittee during their next five meetings from December 1996 through 
Fall 1998. We plan to continue updating the listing with announcements 
in the Federal Register once or twice a year. The next meeting dates 
are December 11-12, 1996. Specific dates for 1997 and 1998 meetings 
will be established at a later time.
    The attached Table 1 lists draft Technical Reports for long-term 
studies on chemicals within known or approximate dates of reviews and 
includes Chemical Abstracts Service (CAS) registry numbers, primary 
use, route of administration, species, exposure levels, and NTP report 
numbers (if assigned).
    Technical Reports of short-term toxicity studies are currently 
reviewed by mail; however, they may be reviewed in open meetings when 
necessary. The attached Table 2 lists the draft Technical Reports of 
short-term toxicity studies tentatively projected for review by mail 
from April 1996 to December 1996 and also includes Chemical Abstracts 
Service (CAS) registry numbers, primary use, route of administration, 
species, exposure levels, and NTP report numbers (if assigned).
    Those interested in having more information about any of the 
studies listed in this announcement should contact Central Data 
Management as early as possible by telephone or by mail at: MD E1-02, 
NIEHS, P.O. Box 12233, Research Triangle Park (RTP), North Carolina 
27709 (919/541-3419). The program would welcome receiving toxicology 
and carcinogenesis data from completed, ongoing or planned studies by 
others as well as current production data, human exposure information, 
and use and use patterns.
    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 will furnish final agendas and other program 
information prior to a meeting, and summary minutes subsequent to a 
meeting.
