Notice Of Intent To List Carbaryl And Spirodiclofen

Comment period extended!

A chemical may be listed under the Safe Drinking Water and Toxic Enforcement Act of 1986 (commonly known as Proposition 65, codified at Health and Safety Code section 25249.5 et seq.) when a body considered to be authoritative by the state’s qualified experts has formally identified the chemical as causing cancer or reproductive toxicity1.  The following entities are identified as authoritative bodies for this purpose:  the U.S. Environmental Protection Agency (U.S. EPA), the International Agency for Research on Cancer, the U.S. Food and Drug Administration, the National Institute for Occupational Safety and Health, and the National Toxicology Program. 

As the lead agency for the implementation of Proposition 65, the Office of Environmental Health Hazard Assessment (OEHHA) within the California Environmental Protection Agency intends to list the chemicals, Carbaryl (CAS No. 63-25-2) and Spirodiclofen (CAS No. 148477-71-8) as known to the State to cause cancer, pursuant to this administrative mechanism. 

Relevant information related to the possible listing of Carbaryl and Spirodiclofen was requested in a notice published in the California Regulatory Notice Register on December 5, 2008 (Register 2008, No. 49‑Z).  OEHHA received and responded to public comments. 

OEHHA has determined that Carbaryl meets the regulatory criteria for listing based on the findings of the U.S. EPA (U.S. EPA, 2002; 2007a; 2007b) and Spirodiclofen meets the criteria for listing based on the findings of the U.S. EPA (U.S. EPA, 2004).  OEHHA is therefore issuing this notice of intent to list Carbaryl and Spirodiclofen under Proposition 65.  A document providing more detail on the scientific basis for the listings of Carbaryl and Spirodiclofen can be obtained from OEHHA’s Proposition 65 Implementation Office at the address and telephone number indicated below, or from the OEHHA Web site.

Comments as to whether Carbaryl and Spirodiclofen meet the regulatory criteria for listing, along with any supporting documentation, may be transmitted via email addressed to P65Public.Comments@oehha.ca.gov or to:
