On July 27, 2001, the Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency, lead agency for the implementation of Proposition 65, proposed to reformat the list of chemicals known to the state to cause reproductive toxicity into a single list, ordered alphabetically by chemical, with the endpoint of concern (developmental, female or male) for listing each chemical clearly noted.

A public workshop was held on September 10, 2001 to receive input on the proposal. Several comments were received supporting the proposal. No comments were received opposing the proposal. Accordingly, OEHHA is reformatting the list of chemicals known to the state to cause reproductive toxicity into a single, alphabetical list. Reformatting of the list is an administrative matter not subject to the Administrative Procedure Act (Health and Safety Code Section 25249.8(e).) Therefore, the reformatted list will be submitted as a "for print only" package to the Office of Administrative Law. The reformatted reproductive toxicity list is included with this notice. The format of the list of chemicals known to the state to cause cancer will not change.

A comment was received that suggested that both the list of chemicals known to cause cancer and the list of chemicals known to cause reproductive toxicity be combined into one single list. After considering the suggestion, it was concluded that this would likely foster confusion for those using the list. Numerous chemicals are included on both the cancer and reproductive toxicity lists, but the dates of addition of a chemical to the two lists are frequently different. Also, the levels and periods of exposure at which the warning requirement of the statute apply to a chemical on both lists are generally different for each form of toxicity, as is the level of discharge triggering the discharge prohibition. Maintaining two separate lists will reduce the possibility of confusion over applicable dates and exposure or discharge levels for chemicals listed under Proposition 65. However, as a service to those who would find it useful, we will, in addition to the reformatted reproductive toxicity list, post a single, combined (cancer and reproductive toxicity) list on the OEHHA Web site at www.oehha.ca.gov.
