{"abstract":"The Environmental Protection Agency (EPA or Agency) is announcing the availability of and seeking public comment on a draft risk evaluation under the Toxic Substances Control Act (TSCA) for 1,2- dichloropropane. The purpose of risk evaluations under TSCA is to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment under the conditions of use (COUs), including unreasonable risk to potentially exposed or susceptible subpopulations identified as relevant to the risk evaluation by EPA, and without consideration of costs or non-risk factors. EPA is seeking comment on the draft risk evaluation for 1,2-dichloropropane.","action":"Notice.","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/2026/09/04/2026-18117.html","cfr_references":[],"citation":"91 FR 56882","comment_url":"http://www.regulations.gov/commenton/EPA-HQ-OPPT-2018-0428-0067","comments_close_on":"2026-11-03","correction_of":null,"corrections":[],"dates":"Comments must be received on or before November 3, 2026.","disposition_notes":null,"docket_ids":["EPA-HQ-OPPT-2018-0428","FRL-13553-01-OCSPP"],"dockets":[{"supporting_documents":[{"title":"18.
