Prioritization 2015: 5 Chemicals For Consultation By The Developmental and Reproductive Toxicant Identification Committee

This notice announces the beginning of a 45-day public comment period on the five chemicals listed below.  These chemicals will be discussed at the November 9, 2015 meeting of the Proposition 65 Developmental and Reproductive Toxicant Identification Committee (DARTIC).  The DARTIC are the state’s qualified experts on reproductive toxicity for purposes of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65).  The DARTIC will provide the Office of Environmental Health Hazard Assessment (OEHHA) with advice on the prioritization of these chemicals for possible preparation of hazard identification materials.  At a later date, OEHHA will select chemicals for preparation of hazard identification materials and announce those decisions in a separate notice.  No listing decisions will be made for these chemicals at the November 9 meeting. 

OEHHA is the lead agency for the implementation of Proposition 65.  The evidence of hazard used in this current round of prioritization is an epidemiologic data screen, previously applied in 2007.  At public meetings of the DARTIC in 2010 and 2011, the Committee endorsed re-application of this screen in future rounds of screening.  For the current application of this epidemiologic data screen, OEHHA rescreened chemicals that had been identified in 2007 as having relevant data but which did not have sufficient human data available at that time to pass the screen.  Chemicals passing the screen were then subjected to a preliminary toxicological evaluation.   This screening follows the procedure described in the 2004 “Process for Prioritizing Chemicals for Consideration under Proposition 65 by the State’s Qualified Experts”.

The five chemicals are:

• Nickel
• Pentachlorophenol
• Perfluorooctanoic acid (PFOA)
• Perfluorooctane sulfonate (PFOS)
• Tetrachloroethylene

The DARTIC will consider these chemicals at its meeting on Monday, November 9, 2015.  The meeting will be held in the Sierra Hearing Room at the CalEPA 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 will send comments received on the prioritization documents for these chemicals to DARTIC members prior to the meeting.

Copies of the summaries of available scientific information on the chemicals and related attachments are available on OEHHA’s web site or may be requested by calling (916) 445-6900. 

Interested parties may provide comment on the extent of the scientific evidence pertaining to the selection of any of these chemicals for possible preparation of hazard identification materials.  OEHHA must receive comments and any supporting documentation on the hazard identification document by 5:00 p.m. on Monday, October 12, 2015 October 14, 2015.  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 “2015 DART Prioritization” in the subject line.  Comments submitted in paper form may be mailed, faxed, or delivered in person to the addresses below:
