The plan defines the purpose and statutory context for EPA-recommended criteria, summarizes scientific work already completed, and organizes stakeholder and expert workshop inputs. It identifies the key science questions covering peer review, human-health risk assessment, indicator and method development and validation, and extrapolation of results via variability assessment and predictive models. It concludes with deferred issues for future research and provides supporting tables and
