    National Toxicology Program (NTP) Board of Scientific Counselors' 
    Meeting; Review of Nominations for Listing in or Delisting From the 9th 
    Report on Carcinogens
    
        Pursuant to Public Law 92-463, notice is hereby given of the next 
    meeting of the NTP Board of Scientific Counselors' Report on 
    Carcinogens (RoC) Subcommittee to be held on December 2 & 3, 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 8:30 a.m. both 
    days and is open to the public. The agenda topics are the peer review 
    of substances, mixtures, or exposure circumstances nominated for 
    listing in or delisting from the 9th Report on Carcinogens, and the 
    provision of the opportunity for public input.
    
    Background
    
        The process for preparation of the Report on Carcinogens (RoC) has 
    three levels of scientific peer review. Central to the evaluations of 
    the review groups is the use of revised criteria, for inclusion in or 
    removal of substances from the Report, which were approved by the 
    Secretary, Department of Health and Human Services (DHHS), in September 
    1996. The major change in the RoC which occurred as a result of the 
    criteria revision was to include consideration of all relevant 
    information, including mechanistic data, in the decision to list in or 
    delist from future volumes. To broaden the scope of scientific review 
    and broaden input to preparation of the Report, a new standing 
    subcommittee of the NTP Board of Scientific Counselors was established 
    in 1996. The meeting on December 2 & 3 will be the third meeting at 
    which the RoC Subcommittee has conducted public review of nominations. 
    The current review process for review of petitions considered by the 
    NTP for listing in or delisting from the RoC begins with initial 
    scientific review by the NIEHS/NTP Report on Carcinogens Review 
    Committee (RG1). The RG1 is comprised of NIEHS/NTP staff scientists. 
    The second scientific review phase is done by the NTP Executive 
    Committee's Working Group for the Report on Carcinogens (RG2). RG2 is 
    comprised of representatives of the Federal health research and 
    regulatory agencies on the
    
    [[Page 57133]]
    
    Executive Committee. The third level of review is the external public 
    review by the RoC Subcommittee and includes time for public comments. 
    The independent recommendations of the three scientific peer review 
    groups and all public comments are presented to the NTP Executive 
    Committee for review and comment. The Director, NTP, receives the four 
    independent recommendations and makes NTP recommendations regarding 
    listing or delisting to the Secretary, DHHS.
    
    Agenda
    
        Tentatively scheduled to be peer reviewed on December 2 & 3 are 11 
    nominations. An alphabetical listing of the nominations with supporting 
    information follows this announcement. The table notes the tentative 
    order of presentation and review in the right hand column, and gives 
    primary uses or exposures and the category for which they were 
    originally nominated. Draft background documents on each of the 
    nominations will be provided to Board Subcommittee reviewers around 
    November 1. Paper copies of draft background documents can be obtained, 
    as available, from: the Board Executive Secretary, Dr. Larry G. Hart, 
    P.O. Box 12233, Research Triangle Park, NC 27709 (telephone 919/541-
    3971; FAX 919/541-0295; emailhart@niehs.nih.gov.)
    
    Public Input Encouraged
    
        The entire meeting is open to the public and time will be provided 
    for public comment on each of the nominations being reviewed. In order 
    to facilitate planning for the meeting, persons wanting to make a 
    formal presentation regarding a particular nomination must notify the 
    Executive Secretary by telephone, by FAX, by mail, or by email no later 
    than November 30, 1998, and, if possible, provide a written copy of 
    their statement in advance of the meeting. Written statements should 
    supplement and may expand on the oral presentation, or may be submitted 
    in lieu of an oral presentation, and should be received by November 30 
    so copies can be made for distribution to Subcommittee members and 
    staff and made available for the public. All attempts will be made to 
    send statements received by November 24 to Subcommittee members in 
    advance of the meeting. Oral presentations must be limited to no more 
    than five minutes.
        Upon request, the Executive Secretary, Dr. Larry G. Hart, at the 
    address given above, will furnish the agenda and a roster of 
    Subcommittee members prior to the meeting. Summary minutes subsequent 
    to the meeting will be available upon request.
