{"abstract":"EPA is issuing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for certain chemical substances that were the subject of premanufacture notices (PMNs) and are also subject to an Order issued by EPA pursuant to TSCA. The SNURs require persons to notify EPA at least 90 days before commencing the manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use in the SNUR. The required notification initiates EPA's evaluation of the conditions of that use for that chemical substance. In addition, the manufacture or processing for the significant new use may not commence until EPA has conducted a review of the required notification; made an appropriate determination regarding that notification; and taken such actions as required by that determination.","action":"Proposed 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/2026/04/24/2026-08012.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"721","title":40}],"citation":"91 FR 22075","comment_url":"http://www.regulations.gov/commenton/EPA-HQ-OPPT-2025-2932-0001","comments_close_on":"2026-05-26","correction_of":null,"corrections":[],"dates":"Comments must be received on or before May 26, 2026.","disposition_notes":null,"docket_ids":["EPA-HQ-OPPT-2025-2932","FRL-13085-01-OCSPP"],"dockets":[{"supporting_documents":[{"title":"EA Final FY25 Batch26-2 V4 EPA HQ OPPT 2025-2932","document_id":"EPA-HQ-OPPT-2025-2932-0010"},{"title":"MMO CAM Standardized Assessments","document_id":"EPA-HQ-OPPT-2025-2932-0009"},{"title":"Metals Bioaccumulation (B) Scores","document_id":"EPA-HQ-OPPT-2025-2932-0008"},{"title":"P-25-0151-0152 Supporting documents","document_id":"EPA-HQ-OPPT-2025-2932-0007"},{"title":"P-25-0151-0152 PMN Sanitized","document_id":"EPA-HQ-OPPT-2025-2932-0006"},{"title":"P-25-0137 Supporting Documents","document_id":"EPA-HQ-OPPT-2025-2932-0005"},{"title":"P-25-0137 PMN Sanitized","document_id":"EPA-HQ-OPPT-2025-2932-0004"},{"title":"P-25-0073 Supporting Documents","document_id":"EPA-HQ-OPPT-2025-2932-0003"},{"title":"P-25-0073 PMN Sanitized","document_id":"EPA-HQ-OPPT-2025-2932-0002"}],"agency_name":"EPA","documents":[{"comment_count":0,"comment_start_date":"2026-04-24","updated_at":"2026-04-24T12:01:19.645-04:00","comment_url":"https://www.regulations.gov/commenton/EPA-HQ-OPPT-2025-2932-0001","allow_late_comments":false,"id":"EPA-HQ-OPPT-2025-2932-0001","comment_end_date":"2026-05-27","regulations_dot_gov_open_for_comment":true}],"supporting_documents_count":9,"id":"EPA-HQ-OPPT-2025-2932","title":"Significant New Use Rules on Certain Chemical Substances (26-2)"}],"document_number":"2026-08012","effective_on":null,"end_page":22083,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/04/24/2026-08012.xml","html_url":"https://www.federalregister.gov/documents/2026/04/24/2026-08012/significant-new-use-rules-on-certain-chemical-substances-26-2","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-08012?publication_date=2026-04-24","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-04-24/2026-08012/mods.xml","not_received_for_publication":null,"page_length":9,"page_views":{"count":234,"last_updated":"2026-04-26 12:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-04-24/pdf/2026-08012.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-08012.pdf?1776948315","publication_date":"2026-04-24","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/04/24/2026-08012.txt","regulation_id_number_info":{"2070-AB27":{"issue":"201404","html_url":"https://www.federalregister.gov/regulations/2070-AB27/significant-new-use-rule-snur-chemical-specific-snurs-to-extend-provisions-of-section-5-e-orders","title":"Significant New Use Rule (SNUR);
