On April 11, 2003, the Office of Environmental Health Hazard Assessment (OEHHA) published a notice in the California Regulatory Notice Register (CRNR) (Register 03, No. 15-Z) requesting information relevant to an assessment of the reproductive and developmental toxicity of perchlorate (ClO4). Perchlorate is a chemical to be considered by OEHHA's Science Advisory Board's Developmental and Reproductive Toxicant (DART) Identification Committee. The publication of the notice initiated a 60 day public comment period which would have closed on June 10, 2003. OEHHA has received requests from interested parties seeking an extension of the comment period to allow interested parties and OEHHA to take into consideration the comments of the peer reviewers of OEHHA's draft Public Health Goal (PHG) document on perchlorate. OEHHA hereby extends the public comment period for perchlorate until 60 days after receipt of the peer reviewers' comments on the draft PHG document for perchlorate. Upon receipt of the peer reviewers' comments by OEHHA, an additional public notice will be published in the CRNR and posted on the OEHHA web site at www.oehha.ca.gov announcing the closing date of the public comment period. This extension of the data call-in for perchlorate does not extend to or in any way affect the comment period or review process in place for the PHG document for perchlorate.
