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 at http://www.oehha.org.
In accordance with the prioritization procedure, on September 12,
1997 we announced the release of the draft data summaries and draft
priorities concerning the potential for 19 chemicals to cause reproductive
toxicity. The notice initiated a 60-day public comment period. No
comments were received on 8 chemicals identified below, while comments
and information were received on the remaining 11 chemicals (also
identified below). Chemicals for which no comments were received
have been assigned final priority status as indicated below. OEHHA
staff are evaluating the submittals on the remaining chemicals,
and the priority status of these chemicals will remain draft until
that process is completed.
