EPA final rule extends compliance dates for methylene chloride TSCA §6 risk management requirements for non-federal laboratories

EPA finalized an extension of certain compliance dates in the TSCA §6 methylene chloride risk management rule for non-federal industrial/commercial laboratories, including Workplace Chemical Protection Program (WCPP) elements (e.g., monitoring, regulated areas/ECEL compliance, and related plans/controls) and associated recordkeeping. This changes when covered laboratories must meet specific WCPP obligations, affecting internal implementation timelines, SOP updates, and contractor/lab compliance planning.
