Notice of Peer Review Meeting with Opportunity for Public Comment.


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 meeting to review two draft documents entitled, “Using Probabilistic Methods to Enhance the Role of Risk Analysis in Decision-Making, with Case Study Examples” and a “Managers' Summary” of the same document. The draft documents were prepared by the Agency's Risk Assessment Forum. The peer review meeting is scheduled to take place on May 6, 2010. On August 18, 2009, EPA announced a 15-day public comment period for the draft documents (74 FR 41695), and on September 17, 2009 extended the comment period to 60 days (74 FR 47794), thus closing the public comment period on October 16, 2009.

The public comment period and the external peer review are separate processes that provide opportunities for all interested parties to comment on the document. In addition to the opportunity provided for public comments through the EPA docket by the closing date of October 16, 2009, the public can provide comments for the external peer reviewers' consideration through the public meeting scheduled for May 6, 2010.

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.Start Printed Page 18206

Additionally, the draft document and the charge questions for EPA's external peer review are available via the Internet on the Risk Assessment Forum's home page at​raf/​prawhitepaper.

In preparing a final report, EPA will consider the peer review report of the recommendations from the external peer review panel and any public comments that EPA receives in accordance with the Federal Register notices noted above on the document and at the public meeting.

End Preamble Start Supplemental Information


Various stakeholders, inside and outside the Agency, have called for a more comprehensive characterization of risks, including uncertainties, in protecting more sensitive or vulnerable populations and life stages. Therefore, the Office of the Science Advisor of the EPA, together with EPA's Science Policy Council and members of EPA's Risk Assessment Forum (RAF), identified a need to examine the use of probabilistic approaches in Agency risk assessment and risk management. An RAF Technical Panel developed this White Paper and the Managers' Summary to provide a general overview of the value of probabilistic analyses and similar or related methods, and some examples of current applications across the Agency. The purpose of these papers is not only to describe potential and actual uses of these tools in the risk decision process, but also to encourage their further implementation in human, ecological, and environmental risk analysis and related decision making. The enhanced use of probabilistic analyses to characterize uncertainty in assessments would not only reflect external scientific advice on how to further advance EPA risk assessment science, but will also help to address specific challenges faced by managers and improve confidence in Agency decisions. The draft document was prepared by the Probabilistic Risk Analysis Technical Panel of EPA's Risk Assessment Forum and has undergone internal peer review at EPA.
