{"abstract":"We, NMFS, announce a 12-month finding on a petition to revise the critical habitat designation under the Endangered Species Act (ESA) for the Southern California steelhead (Oncorhynchus mykiss) distinct population segment (DPS). The petition from the United Water Conservation District (UWCD) requests the removal of an approximately 9-mile (14.5-kilometer (km)) stream reach from the confluence of Hopper Creek and the Santa Clara River to the face of Santa Felicia Dam. Based on our review of the best scientific and commercial data available, we find that the petitioned action to remove this reach from the critical habitat designation is warranted. Consequently, we are proposing to remove this reach from the critical habitat designation for Southern California steelhead.","action":"Notice of 12-month petition finding; proposed rule; request for comments.","agencies":[{"raw_name":"DEPARTMENT OF COMMERCE","name":"Commerce Department","id":54,"url":"https://www.federalregister.gov/agencies/commerce-department","json_url":"https://www.federalregister.gov/api/v1/agencies/54","parent_id":null,"slug":"commerce-department"},{"raw_name":"National Oceanic and Atmospheric Administration","name":"National Oceanic and Atmospheric Administration","id":361,"url":"https://www.federalregister.gov/agencies/national-oceanic-and-atmospheric-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/361","parent_id":54,"slug":"national-oceanic-and-atmospheric-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/06/29/2026-13076.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"226","title":50}],"citation":"91 FR 39046","comment_url":"http://www.regulations.gov/commenton/NOAA-NMFS-2025-0050-0061","comments_close_on":"2026-08-28","correction_of":null,"corrections":[],"dates":"Comments on this proposed rule must be received by August 28, 2026.","disposition_notes":null,"docket_ids":["Docket No. 260624-0152"],"dockets":[{"supporting_documents":[],"agency_name":"NOAA","documents":[{"comment_count":25,"comment_start_date":"2026-06-29","updated_at":"2026-08-25T01:56:15.158-04:00","comment_url":"https://www.regulations.gov/commenton/NOAA-NMFS-2025-0050-0061","allow_late_comments":false,"id":"NOAA-NMFS-2025-0050-0061","comment_end_date":"2026-08-29","regulations_dot_gov_open_for_comment":true}],"supporting_documents_count":0,"id":"NOAA-NMFS-2025-0050","title":"Endangered and Threatened Wildlife and Plants;
