EPA Asks Court for ‘Do Over’ of Third Chemical Risk Analysis (1)

摘要

The EPA is asking a federal court to return another chemical risk evaluation-this time for the emerging contaminant 1,4-dioxane-so the agency can decide whether to alter the analysisinstead of having the court rule on its legality.The Environmental Protection Agency told the U.S. Court of Appeals for the Ninth Circuit on Tuesday that it wanted to revisit the solvent’s “legal, scientific, and policy assumptions andapproaches” it made when conducting the analysis.1,4-dioxane is a likely human carcinogen that can harm the liver, kidneys, and central nervous system at sufficient doses, the EPA has found.
