Availability of Hazard Identification Materials to Support Reconsideration of Listing: 6 Chemicals Listed Via The Labor Code as Known to the State of California to Cause Reproductive Toxicity

The Office of Environmental Health Hazard Assessment (OEHHA) announces the availability for public review of a hazard identification document to support the reconsideration of (n-Butyl glycidyl ether, Diglycidyl ether, Phenyl glycidyl ether, Methyl n-butyl ketone, Methyl isopropyl ketone, α-Methyl styrene) chemicals listed under Proposition 65 as known to cause reproductive toxicity.  The chemicals were added to the Proposition 65 list on the basis of reproductive toxicity via the Labor Code mechanism.1  OEHHA is initiating this action based on changes to the federal regulations that affect the basis for the original listings via the Labor Code mechanism.  Specifically, in March 2012, the federal Occupational Safety and Health Administration (OSHA) amended the regulations contained in CFR2 Title 29, section 1910.1200.  These changes have affected the use of this section as a definitive source for identifying chemicals as known to cause reproductive toxicity by the Labor Code mechanism.

This notice marks the beginning of a 45-day public comment period on this document.  The public comment period will close on Tuesday, February 25, 2014.  Copies of the document are available from OEHHA’s web siteThe document may also be requested from OEHHA’s Proposition 65 Implementation Office by calling (916) 445-6900.

The Developmental and Reproductive Toxicant Identification Committee (DART IC) will consider whether the chemicals covered in the hazard identification document should remain listed under Proposition 65 as known to cause reproductive toxicity.  The DART IC will consider these chemicals at its meeting on Wednesday, March 19, 2014.  The meeting will be held in the Sierra 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 will send comments received on the hazard identification document for these chemicals to DART IC members prior to the meeting.

OEHHA, a department of the California Environmental Protection Agency, is the lead agency for the implementation of Proposition 65.3  The DART IC advises and assists OEHHA in compiling the list of chemicals known to the State to cause reproductive toxicity, as required by Proposition 65.  The DART IC 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.

OEHHA must receive comments and any supporting documentation on the hazard identification document by 5:00 p.m. on Tuesday, February 25, 2014.
