External Peer Review
An external scientific peer review workshop to review the revised draft report, Perchlorate Environmental Contamination: Toxicological Review and Risk Characterization (2002 external review draft) took place on March 5 and 6, 2002, in Sacramento, CA. All questions regarding workshop registration and logistics were directed to EPA's contractor, the Eastern Research Group, Inc. For contact information, please refer to the January 2, 2002, Federal Register notice (and corrections to this notice on the address to submit comments published in the Federal Register on January 14, 2002).
EPA's January 2, 2002, Federal Register notice (67 FR 75) announced the beginning of a 30-day public comment period for the revised draft perchlorate assessment. Because of an approximately one-week delay in public release and availability of the draft document, EPA extended the public comment period to February 19, 2002 (67 FR 3493, January 24, 2002). In response to the high level of interest in this draft document and because of several requests for extension of the comment period, EPA has extended the public comment period by an additional 45 days to April 5, 2002. Comments on the draft document should be in writing and must be received (not postmarked) by April 5, 2002 (67 FR 9271, Feb. 28, 2002). As is the EPA's normal procedure, the Agency will summarize and indicate the disposition of all major comments provided by April 5, 2002, in preparation for its release of the assessment in final form.
