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

EPA issued a final rule (pre-publication copy signed Nov. 7, 2025) extending certain compliance dates for the methylene chloride TSCA Section 6 risk management rule as it applies to industrial/commercial laboratories (non-federal). The pre-publication notice describes an 18-month extension for multiple Workplace Chemical Protection Program (WCPP) and recordkeeping deadlines (e.g., initial monitoring, regulated areas/ECEL compliance, exposure limits methods/exposure control plan). Compliance teams in labs using methylene chloride should update implementation plans, internal deadlines, and contractor/worker protection procedures to reflect the extended dates once confirmed in the Federal Register publication.
