{"abstract":"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.","action":"Final rule.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/06/22/2026-12426.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"370","title":40}],"citation":"91 FR 37022","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective date: This final rule is effective August 21, 2026.","disposition_notes":null,"docket_ids":["EPA-HQ-OLEM-2025-0299","FRL-12698-06-OLEM"],"dockets":[{"supporting_documents":[{"title":"Tier II Form 2027 May2026","document_id":"EPA-HQ-OLEM-2025-0299-0048"},{"title":"Part 370 Regulatory Language Redline Strikeout May 2026","document_id":"EPA-HQ-OLEM-2025-0299-0044"},{"title":"12698-06-OLEM EPCRA HCS Amendments RIA 20260519","document_id":"EPA-HQ-OLEM-2025-0299-0043"},{"title":"12698-06-OLEM EPCRA HCS Amendments RTC 20260508","document_id":"EPA-HQ-OLEM-2025-0299-0042"},{"title":"US BLS Economic Table 4","document_id":"EPA-HQ-OLEM-2025-0299-0041"},{"title":"12698-06-OLEM EPCRA HCS Amendments ICR Supporting Statement 2026019","document_id":"EPA-HQ-OLEM-2025-0299-0040"},{"title":"US BLS Economic Table 3","document_id":"EPA-HQ-OLEM-2025-0299-0039"},{"title":"Environmental Protection Agency Part IV, 40 CFR Part 370, Emergency and Hazardous Chemical Inventory Forms and Community Right-to-Know Reporting Requirements;
