EPCRA Hazardous Chemical Inventory Reporting Requirements: Conformity With the 2024 OSHA Hazard Communication Standard

Document 2026-12426 is a Final Rule published by the Environmental Protection Agency in the Federal Register on June 22, 2026, with an effective date of August 21, 2026. The Environmental Protection Agency is conforming 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-to-Know Act (EPCRA) and its regulations rely on the Occupational Safety and Health Administration's (OSHA'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 conforms 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 improves first responder and community safety, reduces discrepancies and confusion, prevents interpretation burdens on facilities when using (Material) Safety Data Sheets to complete annual hazardous chemical inventory reports, and enhances clarity.
