The Environmental Protection Agency says it is implementing multiple suggested reforms to its Integrated Risk Information System assessments. The revisions include template changes to "substantially reduce the volume of text and address redundancies and inconsistencies in assessments," separating hazard identification and dose-response analysis into their own categories, and improving the transparency of evidence weighting. "The IRIS program recognizes the benefit of adopting a formal weight-of-evidence framework that includes standardized classification of causality," EPA said.
