{"abstract":"We, the National Marine Fisheries Service (NMFS), designate critical habitat for the Cook Inlet beluga whale (Delphinapterus leucas) distinct population segment (DPS) under the Endangered Species Act (ESA). Two areas are designated, comprising 7,800 square kilometers (3,013 square miles) of marine habitat. In developing this final rule we considered public and peer review comments, as well as economic impacts and impacts to national security. We have decided in the final rule to exclude the Port of Anchorage (POA) in consideration of national security interest. Additionally, consistent with the proposed rule, portions of military lands were determined to be ineligible for designation as critical habitat. We solicited comments from the public on all aspects of the proposed rule, and conducted four public hearings on the action. Along with the proposed rule, we published a draft economic impacts analysis, entitled \"Draft RIR/4(b)(2) Preparatory Assessment/IFRA for the Critical Habitat Designation of Cook Inlet Beluga Whale.\" This economic analysis has been completed to support the final designation. See \"Final RIR/4(b)(2) Preparatory Assessment/ FRFA for the Critical Habitat Designation of Cook Inlet Beluga Whale\" for a discussion of these topics.","action":"Final rule.","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/2011/04/11/2011-8361.html","cfr_references":[{"chapter":null,"citation_url":null,"part":226,"title":50}],"citation":"76 FR 20180","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule will become effective on May 11, 2011.","disposition_notes":null,"docket_ids":["Docket No. 090224232-0457-04"],"dockets":[],"document_number":"2011-8361","effective_on":"2011-05-11","end_page":20214,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2011/04/11/2011-8361.xml","html_url":"https://www.federalregister.gov/documents/2011/04/11/2011-8361/endangered-and-threatened-species-designation-of-critical-habitat-for-cook-inlet-beluga-whale","images":{"ER11AP11.000":{"large":"https://img.federalregister.gov/ER11AP11.000/ER11AP11.000_large.png","medium":"https://img.federalregister.gov/ER11AP11.000/ER11AP11.000_medium.png","original_size":"https://img.federalregister.gov/ER11AP11.000/ER11AP11.000_original_size.png"}},"images_metadata":{"ER11AP11.000":{"large":{"identifier":"ER11AP11.000","content_type":"image/png","size":207549,"width":823,"sha":"f14b9411a5e2b41a0cb3a2185ee96bde","url":"https://img.federalregister.gov/ER11AP11.000/ER11AP11.000_large.png","height":1118},"medium":{"identifier":"ER11AP11.000","content_type":"image/png","size":80104,"width":507,"sha":"46b2b0f1f51117cea444721672b601d2","url":"https://img.federalregister.gov/ER11AP11.000/ER11AP11.000_medium.png","height":689},"original_size":{"identifier":"ER11AP11.000","content_type":"image/png","size":895416,"width":3829,"sha":"c1fbc567880202522ef620e3440b2cda","url":"https://img.federalregister.gov/ER11AP11.000/ER11AP11.000_original_size.png","height":5201}}},"json_url":"https://www.federalregister.gov/api/v1/documents/2011-8361?publication_date=2011-04-11","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2011-04-11/2011-8361/mods.xml","not_received_for_publication":null,"page_length":35,"page_views":{"count":2071,"last_updated":"2026-08-24 14:15:12 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2011-04-11/pdf/2011-8361.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2011-04-11","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2011/04/11/2011-8361.txt","regulation_id_number_info":{"0648-AX50":{"issue":"201104","html_url":"https://www.federalregister.gov/regulations/0648-AX50/critical-habitat-designation-for-cook-inlet-beluga-whale-under-the-endangered-species-act","title":"Critical Habitat Designation for Cook Inlet Beluga Whale Under the Endangered Species Act","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201104&RIN=0648-AX50&operation=OPERATION_EXPORT_XML","priority_category":"Other Significant"}},"regulation_id_numbers":["0648-AX50"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-04-30T08:11:23Z"},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":20180,"subtype":null,"title":"Endangered and Threatened Species: Designation of Critical Habitat for Cook Inlet Beluga Whale","toc_doc":"Designation of Critical Habitat for Cook Inlet Beluga Whale","toc_subject":"Endangered and Threatened Species:","topics":["Endangered and threatened species"],"type":"Rule","volume":76}
