Registered speakers using PowerPoint slides with their oral comments should send them to the Designated Federal Officer (see ADDRESSES) by June 14, 2010.

Background Information on CERHR

The NTP established CERHR in 1998 [63 FR 68782]. CERHR is a publicly accessible resource for information about adverse reproductive and/or developmental health effects associated with exposure to environmental and/or occupational exposures. CERHR follows a formal process for the evaluation of selected substances that includes opportunities for public input. CERHR invites the nomination of substances for review or scientists for its expert registry. Information about CERHR and the nomination process can be obtained from its homepage (http://cerhr.niehs.nih.go v) or by contacting Dr. Kristina Thayer (919-541-5021 or CERHR selects substances for evaluation based upon several factors including production volume, potential for human exposure from use and occurrence in the environment, extent of public concern, and extent of data from reproductive and developmental toxicity studies. Expert panels conduct scientific evaluations of substances selected by CERHR in public forums. Following these evaluations, CERHR prepares the NTP-CERHR monograph on the substance evaluated. The monograph is transmitted to appropriate Federal and State agencies and made available to the public.

Background Information on the Report on Carcinogens

The RoC is a public information document prepared for the U.S. Congress by the NTP in response to Section 301(b)(4) of the Public Health Service Act, as amended. The intent of the document is to provide a listing of agents, substances, mixtures, or exposure circumstances that are either known or reasonably anticipated to cause cancer in humans and to which a significant number of people in the United States are exposed. The NTP is following a multi-step scientific review process with multiple opportunities for public input for preparation of the 12th RoC (​go/​29353) that was announced in the Federal Register on April 16, 2007 (72 FR 18999). On several occasions, the NTP has published notices announcing candidate substances under consideration for review for the 12th RoC (69 FR 28940, 69 FR 62276, 70 FR 60548, 72 FR 26394). Publication of the RoC is intended to occur every two years (42 U.S.C. 301(b)(4)); however, in 2007, the NTP initiated a revised and extended review process for the 12th RoC (72 FR 18999). Although the NTP initially planned to review a larger set of candidate substances, in light of the time and resources required to carry out the review process, the NTP has now defined the set of eight candidate substances for the 12th RoC. The three draft substance profiles being peer-reviewed at this BSC meeting are the second and last set of candidate substances that the NTP intends to review for the 12th RoC. The draft substance profiles for the first set of five candidate substances for the 12th RoC were peer reviewed by the BSC at a meeting on February 24, 2009 (​go/​9741). Information about the review of candidate substances for the 12th RoC, including public comments and background documents, is available on the RoC Web site (​go/​10091) or from the RoC Center Director, Dr. Ruth Lunn (919-316-4637 or The remaining candidate substances initially identified for possible review for the 12th RoC may be considered for the 13th RoC.

Background Information on NTP Testing Program Nominations and Proposed Research Projects

The NTP actively seeks to identify and select for study chemicals and other substances for which sufficient information is not available to adequately evaluate potential human health hazards. The NTP accomplishes this goal through a formal, open nomination and selection process. Substances considered appropriate for study generally fall into two broad, yet overlapping categories: (1) Substances judged to have high concern as possible public health hazards based on the extent of human exposure and/or suspicion of toxicity and (2) substances for which toxicological data gaps exist and additional studies would aid in assessing potential human health risks, e.g., by facilitating cross-species extrapolation or evaluating dose-response relationships. Nominations are subject to a multi-step, formal process of review before selections for testing are made and toxicological studies are designed and implemented. The nomination review and selection process is accomplished through the participation of representatives from the NIEHS, other Federal agencies represented on the Interagency Committee for Chemical Evaluation and Coordination (ICCEC)—the NTP Federal interagency review committee for NTP study nominations, the BSC, the NTP Executive Committee—the NTP federal interagency policy body, and the public. The nomination review and selection process is described in further detail on the NTP Web site (​, select “Nominations to the Testing Program”).

Background documents for each nomination are available on the NTP Web site​go/​nom. The NTP invites interested parties to submit written comments, provide supplementary information, or present oral comments at the BSC meeting on the nominated substances and preliminary study recommendations (see “Request for Comments” below). The NTP welcomes toxicology study information from completed, ongoing, or anticipated studies, as well as information on current U.S. production levels, use or consumption patterns, human exposure, environmental occurrence, or public health concerns for any of the nominated substances. The NTP is interested in identifying appropriate animal and non-animal experimental models for mechanistic-based research, including genetically modified rodents and high-throughput in vitro test methods, and as such, solicits comments regarding the use of specific in vivo and in vitro experimental approaches to address questions relevant to the nominated substances and issues under consideration. Although the deadline for submission of written comments to be considered at the BSC meeting is June 7, 2010 (see “Request for Comments” above), the NTP welcomes comments or additional information on these study nominations at any time.

To facilitate review of the proposed research project by the BSC and the public, NTP staff developed a draft research concept document for the nomination recommended for study. A research concept is a brief document Start Printed Page 21005outlining the nomination or study rationale, and the significance, study approach, and expected outcome of a proposed research program tailored for each nomination. The purpose of a research concept is to outline the general elements of a program of study that would address the specific issues that prompted the nomination and the preliminary study recommendations. A research concept may also encompass larger public health issues or topics in toxicology that could be appropriately addressed through studies on the nominated substance(s). Draft research concept will be available on the BSC meeting page (​go/​165) by May 10, 2010.

Background Information on the NTP Board of Scientific Counselors

The BSC is a technical advisory body comprised of scientists from the public and private sectors that provides primary scientific oversight to the NTP. Specifically, the BSC advises the NTP on matters of scientific program content, both present and future, and conducts periodic review of the program for the purpose of determining and advising on the scientific merit of its activities and their overall scientific quality. Its members are selected from recognized authorities knowledgeable in fields such as toxicology, pharmacology, pathology, biochemistry, epidemiology, risk assessment, carcinogenesis, mutagenesis, molecular biology, behavioral toxicology, neurotoxicology, immunotoxicology, reproductive toxicology or teratology, and biostatistics. Members serve overlapping terms of up to four years. The BSC usually meets biannually.
