Technical Amendments to the EPCRA Hazardous Chemical Inventory Reporting Requirements To Conform to the 2024 OSHA Hazard Communication Standard
ACTION: Direct final rule.
SUMMARY: The Environmental Protection Agency is taking direct final action to conform the Emergency Planning and Community Right-to-Know Act hazardous chemical inventory reporting regulations to the Occupational Safety and Health Administration’s Hazard Communication Standard amendments of 2012 and 2024. The Emergency Planning and Community Right-toKnow Act and its regulations rely on the Occupational Safety and Health Administration’s Hazard Communication Standard for the definition of a hazardous chemical and for the categories of health and physical hazards that must be reported under the hazardous chemical inventory regulations. This action will conform the terminology used and information that must be reported on the hazardous chemical inventory forms to the Hazard Communication Standard amendments. As a result, this action will also improve first responder and community safety, reduce discrepancies and confusion, prevent interpretation burdens on facilities when using (Material) Safety Data Sheets to complete annual hazardous chemical inventory reports, and improve clarity.
DATES: This final rule is effective on January 16, 2026 without further notice, unless the EPA receives adverse comment by December 17, 2025.
