Availability of Hazard Identification Materials for Methyl Isocyanate and Announcement of the October 21, 2010 Developmental and Reproductive Toxicant Identification Committee Meeting

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 Developmental and Reproductive Toxicant Identification Committee (DARTIC) advises and assists OEHHA in compiling the list of chemicals known to the State to cause reproductive toxicity 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 reproductive toxicity.”

Methyl isocyanate will be considered for possible listing under Proposition 65 by the DARTIC at its next meeting scheduled for Thursday, October 21, 2010. The meeting will be held in the Coastal Hearing Room at the Cal/EPA Headquarters building, 1001 I Street, Sacramento, California. Thursday’s meeting will begin at 10:00 a.m. and will last until all business is conducted or until 5:00 p.m. The agenda for the meeting will be provided in a future public notice.

OEHHA announces the availability for public review of the document entitled: “Evidence on the Developmental and Reproductive Toxicity of Methyl Isocyanate.” The DARTIC will consider this document in making a listing decision for this chemical. In preparing these hazard identification materials, OEHHA considered information received from its recent request for information relevant to the evidence of reproductive toxicity of methyl isocyanate. The data call-in period for methyl isocyanate opened on June 27, 2008, and closed on August 26, 2008.

Copies of the document are available from OEHHA’s web site. The document may also be requested from OEHHA’s Proposition 65 Implementation Office by calling (916) 445-6900.

We encourage you to submit comments in electronic form, rather than in paper form. Comments transmitted by e-mail should be addressed to sam.delson@oehha.ca.gov.
