Previous studies by the SAB and National Research Council (NRC) have recommended improvements to strengthen EPA scientific assessment practices for decision making. The SAB is undertaking a new study at the request of the EPA Administrator to evaluate the extent to which scientific assessment practices are integrated into EPA’s environmental decision-making processes. The study will build upon the findings of the previous SAB and NRC studies, and recommend actions that EPA could take to improve the integration of scientific assessments for decision making.
