The basic idea of these worksheets is to isolate the computations from the discussions of the computations. The worksheets contain very little discussion and they are intended as a tool to make risk assessment calculations easier to understand and review. Pesticide Coordinators and other technical specialist familiar with HHRAs and ERAs can use these worksheets to develop risk values for the pesticide application rates and application scenarios specific to their particular pesticide project.
