Biological Evaluation Chapters for Diazinon ESA Assessment
EPA has finalized the Biological Evaluation for Diazinon. The final evaluation is based on interim methods developed in conjunction with Fish and Wildlife Service and National Marine Fisheries Service in response to the National Academy of Science report on assessing risks to threatened and endangered species from pesticides.
