{"abstract":"The Environmental Protection Agency (EPA or Agency) is proposing to extend certain compliance dates applicable to certain entities subject to the regulation of perchloroethylene (PCE) and carbon tetrachloride (CTC) under the Toxic Substances Control Act (TSCA). EPA is proposing to extend certain Workplace Chemical Protection Program (WCPP) compliance dates for non-federal owners and operators to match the compliance dates for federal agencies and their contractors. For both PCE and CTC, this proposal would extend the compliance date for initial monitoring for inhalation exposure to June 21, 2027, and extend the compliance date to meet the existing chemical exposure limit (ECEL), establish a regulated area, provide any required respiratory personal protective equipment (PPE), and establish a respiratory PPE program to September 20, 2027. For PCE, EPA is also proposing to extend the compliance date for non-federal entities to establish and implement an exposure control plan to December 20, 2027.","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/2026/03/27/2026-05977.html","cfr_references":[{"chapter":null,"citation_url":null,"part":751,"title":40}],"citation":"91 FR 14790","comment_url":"http://www.regulations.gov/commenton/EPA-HQ-OPPT-2026-0992-0001","comments_close_on":"2026-04-27","correction_of":null,"corrections":[],"dates":"Comments must be received on or before April 27, 2026.","disposition_notes":null,"docket_ids":["EPA-HQ-OPPT-2026-0992","FRL-13023-01-OCSPP"],"dockets":[{"supporting_documents":[{"title":"Carbon Tetrachloride (CTC) Final Risk Evaluation, 2020","document_id":"EPA-HQ-OPPT-2026-0992-0017"},{"title":"Perchloroethylene (PCE) Final Risk Evaluation, 2020","document_id":"EPA-HQ-OPPT-2026-0992-0016"},{"title":"Economic Analysis of the Final Regulation of Carbon Tetrachloride Under TSCA Section 6(a), December 2024","document_id":"EPA-HQ-OPPT-2026-0992-0015"},{"title":"Economic Analysis of the Final Regulation of Perchloroethylene Under TSCA Section 6(a), October 2024","document_id":"EPA-HQ-OPPT-2026-0992-0014"},{"title":"EPA and ACC Chlorine Panel 12/17/2025 Meeting Memo","document_id":"EPA-HQ-OPPT-2026-0992-0013"},{"title":"American Chemistry Council (ACC) Chlorine Panel comment supporting CTC Extension","document_id":"EPA-HQ-OPPT-2026-0992-0012"},{"title":"Aerospace Industries Association (AIA) comment supporting PCE Extension","document_id":"EPA-HQ-OPPT-2026-0992-0011"},{"title":"National Association of Manufacturers (NAM) comment supporting PCE Extension","document_id":"EPA-HQ-OPPT-2026-0992-0010"},{"title":"Olin comment supporting CTC Extension","document_id":"EPA-HQ-OPPT-2026-0992-0009"},{"title":"Chemours comment supporting CTC Extension","document_id":"EPA-HQ-OPPT-2026-0992-0008"}],"agency_name":"EPA","documents":[{"comment_count":0,"comment_start_date":"2026-03-27","updated_at":"2026-03-27T16:57:43.741-04:00","comment_url":"https://www.regulations.gov/commenton/EPA-HQ-OPPT-2026-0992-0001","allow_late_comments":false,"id":"EPA-HQ-OPPT-2026-0992-0001","comment_end_date":"2026-04-28","regulations_dot_gov_open_for_comment":true}],"supporting_documents_count":16,"id":"EPA-HQ-OPPT-2026-0992","title":"Perchloroethylene (PCE) and Carbon Tetrachloride (CTC);
