Draft Hazard Identification Documents for Fenbutatin Oxide and Quizalofop-Ethyl Available

The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) is the lead agency for the implementation of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65).

The Developmental and Reproductive Toxicant (DART) Identification Committee of OEHHA’s Science Advisory Board advises and assists OEHHA in compiling the list of chemicals known to the State to cause reproductive toxicity which is mandated by Health and Safety Code Section 25249.8. The Committee serves as the State’s qualified experts for rendering an opinion as to whether a chemical has been clearly shown, through scientifically valid testing according to generally accepted principles, to cause reproductive toxicity.

On July 16, 1999, OEHHA requested information in relation to the preparation of the draft hazard identification documents on fenbutatin oxide and quizalofop-ethyl to be considered by the DART Identification Committee. The 30-day data call-in ended on August 16, 1999. Information was submitted for quizalofop-ethyl, but no information was received for fenbutatin oxide.

These chemicals were previously under consideration for listing through the authoritative bodies provision of Proposition 65 because they were formally identified by the U.S. Environmental Protection Agency as causing reproductive or developmental toxicity under that agency’s Toxic Release Inventory (TRI) program. After publication of notices of intent to list each of these chemicals, it was determined that the scientific criteria specified in Title 22, California Code of Regulations, Section 12306(g) (22CCR 12306(g)) had not been met. Accordingly, as required by 22 CCR 12306(i), the chemicals have been referred to the DART Identification Committee so that the Committee can determine if the chemicals have been clearly shown by scientifically valid testing according to generally accepted principles to cause reproductive toxicity.

OEHHA has prepared the draft hazard identification documents for fenbutatin oxide and quizalofop-ethyl and announces the availability of the draft documents entitled, "Evidence on the Developmental and Reproductive Toxicity of Fenbutatin Oxide," and "Evidence on the Developmental and Reproductive Toxicity of Quizalofop-Ethyl" for public comment. This notice marks the beginning of a 60-day public comment period. Comments should be directed to:

Cynthia Oshita
Office of Environmental Health Hazard Assessment
301 Capitol Mall, 2nd Floor
Sacramento, California 95814

FAX (916)327-1097

In order to be considered, comments must be postmarked (if sent by mail) or received at OEHHA (if hand-delivered or sent by FAX) by November 16, 1999.

OEHHA will organize and index the comments received and forward the information to the DART Identification Committee members approximately two weeks prior to the meeting at which the candidate chemical will be considered. The next meeting of the DART Identification Committee is scheduled for December 13, 1999. The location will be announced in a future public notice.

Copies of the draft documents are available from the Proposition 65 Implementation office and may be requested by calling (916) 445-6900. The documents are also available from the download area below.
