Request for Information on Perchlorate (ClO4), a Chemical to be Considered by the DART Identification Committee
Request for Information on Perchlorate (ClO4), a Chemical to be Considered by OEHHA's Science Advisory Board's Developmental and Reproductive Toxicant (DART) Identification Committee
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 whether a chemical has been clearly shown through scientifically valid testing according to generally accepted principles to cause reproductive toxicity.
At its December 4, 2002 meeting, the DART Identification Committee considered a petition that the possible listing of perchlorate under Proposition 65 be expedited. The DART Identification Committee recommended that perchlorate be removed from the general prioritization process for chemicals, that it be identified as a high priority candidate for DART Identification Committee consideration, and that OEHHA prepare a hazard identification document as resources permitted.
In accordance with OEHHA's process for preparing information on candidate chemicals for review by the State's qualified experts, OEHHA will review the available literature and data on perchlorate and develop a hazard identification document based on the evidence of its developmental or reproductive toxicity. The DART Identification Committee will consider the hazard identification document before rendering an opinion whether perchlorate has been clearly shown through scientifically valid testing according to generally accepted principles to cause reproductive or developmental toxicity.
Interested parties or members of the public wishing to provide information relevant to an assessment of the reproductive and developmental toxicity of perchlorate should forward such information to the address given below. The publication of this notice marks the start of a 60-day data call-in period. This period ends on Tuesday, June 10, 2003. The information received during this data call-in period will be reviewed and considered by OEHHA as it develops the draft hazard identification document on the reproductive and developmental toxicity of perchlorate.
OEHHA welcomes public participation and public input as part of these scientific assessments. If there is sufficient public interest, a public workshop or other public forum will be held to encourage scientific dialogue prior to completion of the draft hazard identification document.
Notification of the availability of the draft hazard identification document and of the time, date, location, and agenda of any workshop and of the meeting of the DART Identification Committee at which perchlorate will be discussed will be provided in future notices published in the California Regulatory Notice Register and posted on OEHHA's Home Page at www.oehha.ca.gov. The draft hazard identification document will be made available for public comment prior to the committee meeting at which the chemical is considered.
