Notice of Intent to List Chemicals
Additional Extension of Public Comment Period: anthraquinone

The Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65) requires the Governor to publish, and update at least annually, a list of chemicals known to the State to cause cancer or reproductive toxicity. The Office of Environmental Health Hazard Assessment (OEHHA) is the lead agency for the implementation of Proposition 65.

On October 13, 2006, OEHHA published a notice in the California Regulatory Notice Register (Register 06, No. 41-Z) announcing the second extension of the public comment period related to OEHHA’s intent to list anthraquinone under Proposition 65 as a chemical known to the state to cause cancer in accordance with the regulatory criteria in Section 12306 of Title 22 of the California Code of Regulations. The October 13 notice initiated a second 60 day public comment period which would have closed on December 19, 2006. OEHHA has received a another request from an interested party seeking further extension of the comment period to allow for the submission of information from the National Institute of Environmental Health Sciences that may be pertinent to the listing consideration of anthraquinone. OEHHA hereby extends the public comment period for anthraquinone for 60 days to 5 p.m., Tuesday, February 20, 2007.
