Abstract: U.S. EPA pesticide registration decisions are Federal actions covered under Section 7 of the Endangered Species Act. The EPA, US Fish and Wildlife Service, National Marine Fisheries Service and USDA requested a review by the National Research Council to provide guidance on advancing a consistent and coordinated pesticide risk assessment methodology for listed species. The NRC published its report in 2013 and recommended: a common risk assessment process based on EPA’s ecological risk assessment framework; a spatially and temporally-explicit exposure modeling framework; approaches to assess sub-lethal effects and population responses; methods for evaluating mixtures of pesticides and other chemicals; and implementation of probability-based risk estimates. The EPA, Services, and USDA are collaborating in the implementation of the new risk assessment methods through the EPA’s pesticide re-evaluation program. There remains the need to fully establish a harmonized risk assessment methodology and resolve policy and regulatory issues concerning the use of local agronomic practices to devise practical and effective risk mitigation measures when required.
