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).

The Carcinogen Identification Committee of OEHHA's Science Advisory Board advises and assists OEHHA in compiling the list of chemicals known to the State to cause cancer, which is mandated by Health and Safety Code Section 25249.8. The Committee serves as the State's qualified experts for rendering an opinion whether a chemical has been clearly shown, through scientifically valid testing according to generally accepted principles, to cause cancer.

On August 6, 1999, OEHHA requested information in relation to the preparation of draft hazard identification documents on seven chemicals to be considered by the Carcinogen Identification Committee for possible addition to the Proposition 65 list. Three chemicals for which documents have been drafted are hexachlorobutadiene, 4-methylquinoline, and MX(3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone). (Hazard identification documents on the other four chemicals are in preparation by OEHHA.) The 60-day data call-in ended on October 5, 1999. No information or data were received on any of the seven chemicals.

The three draft hazard identification documents currently available are entitled: "Evidence on the Carcinogenicity of Hexachlorobutadiene," "Evidence on the Carcinogenicity of 4-Methylquinoline," and "Evidence on the Carcinogenicity of MX(3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone)." Copies of the draft documents are available from the Proposition 65 Implementation Office and may be requested by calling (916) 445-6900. This notice marks the beginning of a 60-day public comment period. Comments should be submitted in triplicate and directed to:

In order to be considered, comments must be postmarked (if sent by mail) or received at OEHHA (if hand-delivered or sent by fax) by 5:00 p.m. on Tuesday, October 24, 2000.

OEHHA will organize and index the comments received and forward the information to the Carcinogen Identification Committee members at least two weeks prior to the meeting at which the candidate chemical will be considered. The next meeting of the Carcinogen Identification Committee is scheduled for Thursday, November 16, 2000. The meeting will be held at Training Room B, Elihu Harris State Building, 1515 Clay Street, Oakland, California [map].
