This document determines what regulatory actions EPA should take under FIFRA to change the current use patterns of pesticides containing EDB. Included are discussions about the risks and benefits of the pesticidal uses of EDB, and explanations about the rationale for the Agency's proposed final decision. This document is written in five chapters. Chapter I is this introductory section. Chapter II summarizes and evaluates the comments received on the RPAR, evaluates the potential health risks of EDB, and briefly describes the laboratory evidence of toxicity, available exposure data, available epidemiology data and the Agency's revised risk assessment. Chapter III summarizes the use-by-use economic benefits of EDB and the assumptions and limits of these estimates. Chapter IV describes possible regulatory options for the reduction of risks. Chapter V evaluates the risks and benefits and adverse impacts of each possible action for each of the nine general categories of the registered uses of EDB, and selects the regulatory action the Agency is proposing for each use.
