On January 7, 2016 the U.S. Environmental Protection Agency (EPA) announced the release of the external review draft of ``Guidelines for Human Exposure Assessment'' for public review and comment (81 FR 774-775). With this notice EPA is announcing the extension of the comment period to March 22, 2016. EPA is seeking public comment prior to external peer review. The document will undergo review during an expert peer review meeting, which will be convened, organized, and conducted by an independent contractor. The date and location of the peer review meeting will be announced in a subsequent Federal Register notice. All comments received in the docket by the closing date March 22, 2016 will be shared with the peer review panel for their consideration. Comments received after the close of the comment period may be considered by EPA when it finalizes the document.
