EPA-HQ-OPP-2020-0263).

Biographies of these candidates are available on the FIFRA SAP website at Public comments – which must be submitted on or before July 31, 2020 – will be used to assist the Agency in selecting ad hoc participants for the upcoming review.

Knott (, M.S., Designated Federal Officer, Office of Science Coordination and Policy, Environmental Protection Agency (202-564-0103).

The FIFRA SAP serves as a primary scientific peer review mechanism of EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP) and is structured to provide scientific advice, information and recommendations to the EPA Administrator on pesticides and pesticide-related issues as to the impact of regulatory actions on health and the environment. During the meeting on September 15-18, 2020, the FIFRA SAP will consider and review EPA activities that could inform human health risk assessment for organophosphate pesticides and reducing animal testing. EPA is considering using in vitro data for 16 organophosphate compounds to potentially reduce reliance on default risk assessment uncertainty factors in favor of more refined data-derived factors.
