The California Environmental Protection Agency's Office of Environmental Health Hazard Assessment (OEHHA) is the lead agency for the implementation of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). As the lead agency, OEHHA has developed a procedure for prioritizing chemicals for consideration under Proposition 65 by the "State's qualified experts". Two committees of the Science Advisory Board (SAB), known as the Carcinogen Identification Committee, and the Developmental and Reproductive Toxicant (DART) Identification Committee, serve as the State's qualified experts for rendering an opinion as to whether a chemical is known to the State to cause cancer, birth defects or other reproductive harm.

The procedure used by OEHHA to identify, prioritize and select candidate chemicals for evaluation by the SAB Committees is described in, "Procedure for Prioritizing Candidate Chemicals for Consideration Under Proposition 65 by the State's Qualified Experts," May 1997 available on the Internet. This procedure ensures that chemicals posing the highest level of cancer, birth defects or reproductive hazard concern are addressed first and forthwith by the SAB. In accordance with the prioritization procedure, on October 4, 1996 we announced the release of the draft data summaries and draft priorities concerning the potential for the chemicals indicated below to cause birth defects or other reproductive harm. The notice initiated a 60-day public comment period. Several comments and information were received. OEHHA staff evaluated the submittals. The comments and information received did not change the draft priority assignments. The final priority assignments for the chemicals are:

CASRN = Chemical Abstracts Service Registration Number

Chemicals Under Consideration for Possible Listing Via Administrative Mechanism

CASRN = Chemical Abstracts Service Registration Number
_aUnder evaluation to determine whether the chemical meets the criteria for the authoritative bodies mechanism in 22 CCR Section 12306, see the notice published in the California Regulatory Notice Register on August 22, 1997.

Chemicals Which Were Postponed From Consideration

_aCASRN = Chemical Abstracts Service Registration Number
Renewed consideration with respect to the chemical's potential to cause birth defects or other reproductive harm. Draft data summary, draft priority and a request for relevant information is announced elsewhere in today's register.

Copies of the final data summaries and priority assignments for these chemicals are available from the Proposition 65 Implementation Office at the address and telephone number indicated below, or from the Internet.
