AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice of Peer-Review Workshop.

SUMMARY:

EPA is announcing that Eastern Research Group, Inc. (ERG), an EPA contractor for external scientific peer review, will convene an independent panel of experts and organize and conduct an external peer-review workshop on March 3-4, 2010, to review the external review draft document titled, “Exposure Factors Handbook 2009 Update” (EPA/600/R-09/052A). EPA previously announced the 60-day public comment period (ending December 7, 2009) for the draft document in the Federal Register on October 7, 2009 (74 FR 51592). The draft document was prepared by the National Center for Environmental Assessment (NCEA) within EPA's Office of Research and Development. The Exposure Factors Handbook provides information on various physiological and behavioral factors commonly used in assessing exposure to environmental chemicals. The handbook was first published in 1989 and was updated in 1997. This updated version incorporates data available since 1997 up to June 2009. It also reflects the revisions made to the Child-Specific Exposure Factors Handbook, which was updated and published in 2008. Each chapter in the revised Exposure Factors Handbook presents recommended values for the exposure factors covered in the chapter as well as a discussion of the underlying data used in developing the recommendations.

The public comment period and the external peer-review workshop are separate processes that provide opportunities for all interested parties to comment on the document. EPA intends to forward public comments submitted in accordance with the October 7, 2009, Federal Register notice (74 FR 51592) to ERG, for consideration by the external peer-review panel prior to the workshop. EPA will consider public comments and recommendations from the expert panel workshop as EPA finalizes the draft document.

EPA is releasing this draft document solely for the purpose of pre-dissemination peer review under applicable information quality guidelines. This document has not been formally disseminated by EPA. It does not represent and should not be construed to represent any Agency policy or determination.

ERG invites the public to register to attend this workshop as observers. In addition, ERG invites the public to give oral comments at the workshop regarding the draft document under review. Members of the public interested in making oral comments at the workshop should also provide ERG with an electronic copy of their comments. Space is limited, and reservations will be accepted on a first-come, first-served basis. The draft document and EPA's peer-review charge are only available via the Internet on NCEA's home page under the Recent Additions menu at http://www.epa.gov/​ncea. In preparing a final report, EPA will consider ERG's report of the comments and recommendations from the external peer-review workshop and any public comments that EPA received.

The peer-review panel workshop will begin on Wednesday, March 3, 2010, at 8 a.m., and will end on Thursday, March 4, 2010, at Start Printed Page 5318approximately 12 p.m. Eastern Standard Time.
