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.
Perchlorate (ClO4) is a chemical to be considered by the DART Identification Committee. OEHHA will develop a hazard identification document based on the evidence of perchlorate’s developmental and reproductive toxicity. Initially, the public comment period to submit information relevant to the assessment of the developmental and reproductive toxicity of perchlorate was to close on June 10, 2003. On June 6, 2003, OEHHA published a notice in the California Regulatory Notice Register (CRNR) (Register 03, No. 23-Z) extending the public comment period for such relevant information at the request of several interested parties until 60 days after receipt of the peer reviewers’ comments on OEHHA’s draft Public Health Goal document for perchlorate. The peer reviewers’ comments have been received. The publication of this notice announces the close of the 60-day data call-in period. This period ends on Tuesday, April 27, 2004. The information received during this data call-in period will be reviewed and considered by OEHHA as it develops the draft hazard identification document (HID) on the reproductive and developmental toxicity of perchlorate. If new information becomes available after the close of this comment period and during the development of the draft HID, OEHHA will incorporate it into the document. OEHHA does not anticipate submitting the draft HID for public comment and Committee consideration before 2005.
OEHHA welcomes public participation and public input as part of these scientific assessments. A public workshop or other public forum will be held as part of the public comment process. Notification of the availability of the draft hazard identification document and of the time, date, location, and agenda of the 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.
