EPA worked with the Departments of Agriculture, Commerce and the Interior to develop the following Interim Approaches for Pesticide Endangered Species Act Assessments based on National Academy of Sciences Report Recommendations. The interim approaches were used by EPA to finalize biological evaluations for the three pilot chemicals: chlorpyrifos, diazinon and malathion in 2017. The Draft Revised Method for National Level Endangered Species Risk Assessment Process for Biological Evaluations of Pesticides released in May 2019 is an important step in further refining the interim approaches.
