Registration for oral comments will also be available at the meeting, although time allowed for presentation by on-site registrants may be less than that for preregistered speakers and will be determined by the number of persons who register on-site. Background Information on NTP Panels NTP panels are technical, scientific advisory bodies established on an ‘‘as needed’’ basis to provide independent scientific peer review and to advise the NTP on agents of public health concern, new/revised toxicological test methods, or other issues. These panels help ensure transparent, unbiased, and scientifically rigorous input to the program for its use in making credible decisions about human hazard, setting research and testing priorities, and providing information to regulatory agencies about alternative methods for toxicity screening. The NTP welcomes nominations of scientific experts for upcoming panels. Scientists interested in serving on an NTP panel should provide a current curriculum vita to Ms. Andrews (see ADDRESSES). The authority for NTP panels is provided by 42 U.S.C. 217a; section 222 of the Public Health Service (PHS) Act, as amended. The panel is governed by the Federal Advisory Committee Act, as amended (5 U.S.C. Appendix 2), which sets forth standards for the formation and use of advisory committees. Dated: December 7, 2011.
