The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA), as lead agency for the implementation of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65), 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 is available on the Internet at http://www.oehha.ca.gov. 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, we are announcing 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. This notice initiates a 60-day public comment period. The chemicals are:

CASRN = Chemical Abstracts Service Registration Number

Chemicals Postponed From Consideration

CASRN = Chemical Abstracts Service Registration Number

^a Under evaluation to determine whether the chemical meets the criteria for the authoritative bodies mechanism in 22 CCR Section 12306.

OEHHA also announces that a public workshop to receive external scientific peer review and public comments on the draft data summaries and draft priority assignments for these chemicals will be held on Wednesday, October 29, 1997. The workshop will commence at 10:00 a.m. in the Auditorium at 714 P Street, Sacramento, California, and will last until all business has been conducted or until 5:00 p.m.

OEHHA is committed to public participation and external scientific peer review in its implementation of Proposition 65, and welcomes public input. As part of its efforts to ensure that regulatory decisions are based upon a thorough consideration of all relevant information, OEHHA is soliciting information, scientific data and scientific peer review which may be relevant to the evaluation of these chemicals within the context of Proposition 65. The draft data summaries and draft 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 at the following address: http://www.oehha.ca.gov.
