These two species are endemic to portions of the Cumberland and Tennessee River systems of Alabama, Kentucky, Mississippi, Tennessee, and Virginia. The effect of this regulation is to add these species to the List of Endangered and Threatened Wildlife and to implement the Federal protections provided by the Act for these species.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF THE INTERIOR","name":"Interior Department","id":253,"url":"https://www.federalregister.gov/agencies/interior-department","json_url":"https://www.federalregister.gov/api/v1/agencies/253","parent_id":null,"slug":"interior-department"},{"raw_name":"Fish and Wildlife Service","name":"Fish and Wildlife Service","id":197,"url":"https://www.federalregister.gov/agencies/fish-and-wildlife-service","json_url":"https://www.federalregister.gov/api/v1/agencies/197","parent_id":253,"slug":"fish-and-wildlife-service"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2013/09/26/2013-23356.html","cfr_references":[{"chapter":null,"citation_url":null,"part":17,"title":50}],"citation":"78 FR 59269","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective on October 28, 2013.","disposition_notes":null,"docket_ids":["Docket No. FWS-R4-ES-2012-0004","4500030113"],"dockets":[],"document_number":"2013-23356","effective_on":"2013-10-28","end_page":59287,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2013/09/26/2013-23356.xml","html_url":"https://www.federalregister.gov/documents/2013/09/26/2013-23356/endangered-and-threatened-wildlife-and-plants-endangered-species-status-for-the-fluted-kidneyshell","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2013-23356?publication_date=2013-09-26","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2013-09-26/2013-23356/mods.xml","not_received_for_publication":null,"page_length":19,"page_views":{"count":471,"last_updated":"2026-04-04 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2013-09-26/pdf/2013-23356.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2013-23356.pdf?1380113367","publication_date":"2013-09-26","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2013/09/26/2013-23356.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Literature Cited for Fluted Kidneyshell and Slabside Pearlymussel Final Listing Rule, 2013","document_id":"FWS-R4-ES-2012-0004-0015"},{"title":"Draft Economic Analysis of Critical Habitat Designation for the Flulted Kidneyshell and Slabside Pearlymussel","document_id":"FWS-R4-ES-2012-0004-0012"},{"title":"Plan for Peer Review of Scientific Information for Fluted Kidneyshell and Slabside Pearlymussel","document_id":"FWS-R4-ES-2012-0004-0003"},{"title":"Literature Cited for Fluted Kidneyshell and Slabside Pearlymussel Proposed Rule","document_id":"FWS-R4-ES-2012-0004-0002"}],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/1018-AY06/endangered-and-threatened-wildlife-and-plants-listing-determination-for-two-tennessee-river-mussels","title":"Endangered and Threatened Wildlife and Plants; Listing Determination for Two Tennessee River Mussels"},"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=FWS-R4-ES-2012-0004","supporting_documents_count":4,"docket_id":"FWS-R4-ES-2012-0004","regulation_id_number":"1018-AY06","title":"Endangered Status for the Fluted Kidneyshell and Slabside Pearlymussel and Designation of Critical Habitat","checked_regulationsdotgov_at":"2013-10-16T08:00:58Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":59269,"subtype":null,"title":"Endangered and Threatened Wildlife and Plants; Endangered Species Status for the Fluted Kidneyshell and Slabside Pearlymussel","toc_doc":"Endangered Species Status for the Fluted Kidneyshell and Slabside Pearlymussel","toc_subject":"Endangered and Threatened Wildlife and Plants:","topics":["Endangered and threatened species","Exports","Imports","Reporting and recordkeeping requirements","Transportation"],"type":"Rule","volume":78}
