**SUPPLEMENTARY INFORMATION:**
**Background Information on the CERHR**
The NTP established the CERHR in June 1998 [ *Federal Register* , December 14, 1998 (Vol. 63, No. 239, pp. 68782)]. The 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. Expert panels conduct scientific evaluations of agents selected by the CERHR in public forums.
The CERHR invites the nomination of agents for review or scientists for its expert registry. Information about CERHR and the nomination process can be obtained from its Web site ( *http://cerhr.niehs.nih.gov* ) or by contacting Dr. Shelby (see *ADDRESSES* above). The CERHR selects chemicals 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.
The CERHR follows a formal, multi-step process for review and evaluation of selected chemicals. The formal evaluation process was published in the *Federal Register* notice July 16, 2001 (Vol. 66, No. 136, pp. 37047-37048) and is available on the CERHR Web site under “About CERHR” or in printed copy from the CERHR.
