Extension of Public Comment Period - Notice of Intent to List Chemicals: butyl benzyl phthalate (BBP), di-n-butyl phthalate (DBP), di-n-hexyl phthalate (DnHP), and di-isodecyl phthalate (DIDP)

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 March 4, 2005, OEHHA published a notice in the California Regulatory Notice Register (Register 05, No. 9-Z) announcing its intent to list butyl benzyl phthalate (BBP), di-n-butyl phthalate (DBP), di-n-hexyl phthalate (DnHP), and di-isodecyl phthalate (DIDP) under Proposition 65 as chemicals known to the state to cause reproductive toxicity in accordance with the regulatory criteria in Section 12306 of Title 22 of the California Code of Regulations. The publication of the notice initiated a 30-day public comment period which would have closed on April 4, 2005. OEHHA has received a request from an interested party seeking an extension of the comment period to allow for the submittal submission of complete and relevant scientific information. OEHHA hereby extends the public comment period for butyl benzyl phthalate (BBP), di-n-butyl phthalate (DBP), di-n-hexyl phthalate (DnHP), and di-isodecyl phthalate (DIDP) to 5 p.m., Tuesday, May 24, 2005.
