Hazard Identification Documents for Butyl Benzyl Phthalate and Diisononyl Phthalate (DINP) to be Considered at the December 5, 2013 CIC Meeting

Announcement of the Carcinogen Identification Committee Meeting Scheduled for December 5, 2013 and the Availability of Hazard Identification Documents for Butyl Benzyl Phthalate and Diisononyl Phthalate

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 19861 (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.

Butyl benzyl phthalate and diisononyl phthalate will be considered for possible listing by the CIC at its next meeting scheduled for Thursday, December 5, 2013.  The meeting will be held in the Coastal Hearing Room at the Cal/EPA Headquarters building, 1001 I Street, Sacramento, California.  The 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 published in advance of the meeting.

OEHHA announces the availability for public review of the documents entitled:  “Evidence on the Carcinogenicity of Butyl Benzyl Phthalate” and “Evidence on the Carcinogenicity of Diisononyl Phthalate.”  The CIC will consider these documents in making any listing decisions on these chemicals.  In preparing these hazard identification documents, OEHHA considered information received from its requests for information relevant to the evidence of carcinogenicity of butyl benzyl phthalate and diisononyl phthalate.  The data call-in period for butyl benzyl phthalate opened on November 23, 2012 and closed on January 22, 2013.  The data call-in period for diisononyl phthalate opened October 16, 2009 and closed on February 16, 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 45-day public comment period on these two documents.  OEHHA must receive comments and any supporting documentation by 5:00 p.m. on Monday, November 18, 2013.  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.  Please include “HID – BBP” or “HID – DINP” in the subject line.  Comments submitted in paper form may be mailed, faxed, or delivered in person to the addresses below:
