Assessing Risks to Endangered and Threatened Species from Pesticides; 5th Interagency Workshop on Joint Interim Approaches to NAS Recommendations

For Release:  June 13, 2016

On June 29 and 30, 2016, EPA and its federal partners, Fish and Wildlife Service, National Marine Fisheries Service, and U.S. Department of Agriculture, will hold a two-day workshop. This workshop will offer a forum for stakeholder suggestions for refining some of the interim scientific methods used in the recently released draft Biological Evaluations (BEs) for three pilot chemicals: chlorpyrifos, diazinon, and malathion. These BEs are the first nationwide endangered species risk assessments. They were developed by EPA, FWS, and NMFS (with collaboration from USDA on crop production, use, and geospatial data on agricultural use patterns) in response to the 2013 National Academy of Sciences (NAS) report entitled, “Assessing Risks to Endangered and Threatened Species from Pesticides.”  

This workshop builds on the previously held public meetings in November 2013, April 2014, October 2014, and April 2015 and follows the enhanced stakeholder engagement process that was finalized in March 2013. This public meeting furthers the agencies’ goal of developing a consultation process for pesticide impacts on listed species that is efficient, inclusive, and transparent. 

The opening and concluding plenary sessions of the workshop will be open to the general public.  The other sessions (breakout sessions) will be by invitation only by the Workshop Steering Committee given meeting space limitations.  The Workshop Steering Committee is composed of members from EPA, FWS, NMFS, and representatives from industry, grower groups, and environmental non-governmental organizations. There may be a limited number of  spots for the general public if space allows.  Breakout sessions will discuss technical questions related to the three main topics of interest: 1) improving aquatic modeling, 2) refinements to interim method for Step 1 and Step 2, and 3) the approach to the weight of evidence.
