{"abstract":"The Coast Guard is establishing a temporary safety zone for navigable waters of the St. Clair River for 7.5 miles beginning in Port Huron, MI. Though this is an unsanctioned, non-permitted marine event, this zone is necessary to provide for the safety of life on these navigable waters during a float down event near Port Huron, MI. Entry into this zone of vessels or non-participants in the event is prohibited unless specifically authorized by the Captain of the Port Detroit (COTP) or their designated representative.","action":"Temporary final rule.","agencies":[{"raw_name":"DEPARTMENT OF HOMELAND SECURITY","name":"Homeland Security Department","id":227,"url":"https://www.federalregister.gov/agencies/homeland-security-department","json_url":"https://www.federalregister.gov/api/v1/agencies/227","parent_id":null,"slug":"homeland-security-department"},{"raw_name":"Coast Guard","name":"Coast Guard","id":53,"url":"https://www.federalregister.gov/agencies/coast-guard","json_url":"https://www.federalregister.gov/api/v1/agencies/53","parent_id":227,"slug":"coast-guard"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/08/14/2026-16644.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"165","title":33}],"citation":"91 FR 52533","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective from 12 p.m. through 6 p.m. on August 16, 2026.","disposition_notes":null,"docket_ids":["Docket Number USCG-2026-0995"],"dockets":[{"supporting_documents":[{"title":"REC_DSS_USCG_2026_26039","document_id":"USCG-2026-0995-0002"}],"agency_name":"USCG","documents":[{"comment_count":null,"comment_start_date":null,"updated_at":"2026-08-14T10:03:40.389-04:00","comment_url":"https://www.regulations.gov/commenton/USCG-2026-0995-0001","allow_late_comments":false,"id":"USCG-2026-0995-0001","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":1,"id":"USCG-2026-0995","title":"Safety Zone; St. Clair River; Port Huron, MI"}],"document_number":"2026-16644","effective_on":"2026-08-16","end_page":52534,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/08/14/2026-16644.xml","html_url":"https://www.federalregister.gov/documents/2026/08/14/2026-16644/safety-zone-st-clair-river-port-huron-mi","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-16644?publication_date=2026-08-14","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-08-14/2026-16644/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":128,"last_updated":"2026-10-24 18:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-08-14/pdf/2026-16644.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-16644.pdf?1786625119","publication_date":"2026-08-14","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/08/14/2026-16644.txt","regulation_id_number_info":{"1625-AA00":{"issue":"201104","html_url":"https://www.federalregister.gov/regulations/1625-AA00/safety-zone-regulations","title":"Safety Zone Regulations","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201104&RIN=1625-AA00&operation=OPERATION_EXPORT_XML","priority_category":"Routine and Frequent"}},"regulation_id_numbers":["1625-AA00"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"REC_DSS_USCG_2026_26039","document_id":"USCG-2026-0995-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/1625-AA00/safety-zone-regulations","title":"Safety Zone Regulations"},"comments_count":0,"agency_id":"USCG","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=USCG-2026-0995","supporting_documents_count":1,"docket_id":"USCG-2026-0995","document_id":"USCG-2026-0995-0001","regulation_id_number":"1625-AA00","title":"Safety Zone; St. Clair River; Port Huron, MI","checked_regulationsdotgov_at":"2026-08-15T18:55:11Z"},"regulations_dot_gov_url":null,"significant":false,"signing_date":null,"start_page":52533,"subtype":null,"title":"Safety Zone; St. Clair River; Port Huron, MI","toc_doc":"St. Clair River, Port Huron, MI","toc_subject":"Safety Zone","topics":["Harbors","Marine safety","Navigation (water)","Reporting and recordkeeping requirements","Security measures","Waterways"],"type":"Rule","volume":91}
