Carcinogen Identification Committee Meeting September 21 and 22, 2010 and Hazard Identification Materials for 1,3-Dichloro-2-propanol (1,3 DCP) and 3-Monochloropropane-1,2-diol (3-MCPD)

Announcement of a Carcinogen Identification Committee Meeting Scheduled for September 21 and 22, 2010, and Availability of Hazard Identification Materials for 1,3-Dichloro-2-propanol (1,3 DCP) and 3-Monochloropropane-1,2-diol (3-MCPD)

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) 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.

1,3-Dichloro-2-propanol (1,3 DCP) and 3-monochloropropane-1,2-diol (3-MCPD) will be considered for possible listing under Proposition 65 by the CIC at its next meeting scheduled for Tuesday and Wednesday, September 21 and 22, 2010. The two-day meeting will be held in the Sierra Hearing Room at the Cal/EPA Headquarters building, 1001 I Street, Sacramento, California. The meetings will begin each day at 10:00 a.m. and will last until 5:00 p.m. on Tuesday and until all business is conducted or until 5:00 p.m on Wednesday. The agenda for the two day meeting will be provided in a future public notice published in advance of the meeting.

OEHHA announces the availability for public review of the documents entitled: “Evidence on the Carcinogenicity of 1,3-Dichloro-2-propanol (1,3 DCP)” and “Evidence on the Carcinogenicity of 3-Monochloropropane-1,2-diol (3-MCPD).” The CIC will consider these documents in making any listing decisions on these chemicals. In preparing these hazard identification materials, OEHHA considered information received from its recent request for information relevant to the evidence of carcinogenicity of 1,3-DCP and 3-MCPD. The data call-in period opened on October 16, 2009, and closed on January 7, 2010.

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

This notice marks the beginning of a 60-day public comment period on these two documents. OEHHA must receive comments and any supporting documentation by 5:00 p.m. on Tuesday, August 24, 2010. We encourage you to submit comments in electronic form, rather than in paper form. Comments transmitted by e-mail should be addressed to P65Public.Comments@oehha.ca.gov.
