Request for Public Comments To Be Sent to EPA on Peer Review Materials To Inform the Safe Drinking Water Act Decision Making on Perchlorate

The U.S. Environmental Protection Agency (EPA) is announcing the release of materials for public comment that will undergo expert peer review in support of the EPA's Safe Drinking Water Act decision making on perchlorate. This request is one of two Federal Register notices being published concurrently, seeking public comment on two separate sets of peer review materials. The Agency requests comment on both the draft Biologically Based Dose-Response Model and an accompanying draft model report entitled ``Biologically Based Dose- Response Models for the Effect of Perchlorate on Thyroid Hormones in the Infant, Breast Feeding Mother, Pregnant Mother, and Fetus: Model Development, Revision, and Preliminary Dose-Response Analyses.'' These materials will be reviewed by an expert peer review panel and the panelists will consider the public comments received. A companion notice published on this date requests comments on the interim list of peer reviewers and draft peer review charge questions to be sent to EPA's contractor, Versar, Inc.
