Implementing NAS Report Recommendations on Ecological Risk Assessment for Endangered and Threatened Species
In 2011, the EPA and the Departments of Agriculture, Commerce and the Interior requested that the National Research Council of the National Academy of Science convene a committee of independent experts to examine topics pertaining to tools and approaches for assessing the effects of proposed FIFRA actions on endangered and threatened species and their critical habitats.
The NRC was asked to consider a range of issues, including:
- identifying best available scientific data and information;
- considering sub-lethal, indirect and cumulative effects;
- assessing the effects of chemical mixtures and inert ingredients;
- using models to assist in analyzing the effects of pesticide use;
- incorporating uncertainties into the evaluations effectively; and
- using geospatial information and datasets in the course of these assessments.
Since receiving the NAS report, the agencies have been working together to develop shared scientific approaches that reflect the advice provided by the NAS. Working together, scientists from the requesting agencies have met, analyzed the recommendations and have developed interim approaches they will jointly implement as part of a phased iterative process. They are also identifying future tools, models and approaches that will need to be developed some time over a period of years.
These methods may be further refined as we conduct ESA assessments on additional chemicals. (20 pp, 977 K, About PDF)
