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 (CIC) of OEHHA’s Science Advisory Board advises and assists OEHHA in compiling the list of chemicals known to the State to cause cancer as required by Health and Safety Code section 25249.8. The Committee serves as the State’s qualified experts for determining whether a chemical has been clearly shown through scientifically valid testing according to generally accepted principles to cause cancer.

On March 12, 2004, OEHHA requested information in relation to the preparation of a draft hazard identification documents on 1,2-epoxybutane and verapamil, chemicals to be considered by the CIC for possible addition to the Proposition 65 list. The 60 day data call-in period ended on May 11, 2004. No information or data were received on 1,2-epoxybutane or verapamil.

OEHHA has prepared the draft hazard identification documents for 1,2-epoxybutane and verapamil and announces the availability of the draft documents entitled: “Evidence on the Carcinogenicity of 1,2-epoxybutane” and “Evidence on the Carcinogenicity of Verapamil.” Copies of the draft documents are available from the Proposition 65 Implementation Office and may be requested by calling (916) 445-6900.
