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.
Relevant information on perchlorate should be sent in triplicate
by mail or fax to:
