Fish and Wildlife Service August 22, 2023 – Federal Register Recent Federal Regulation Documents

We, the U.S. Fish and Wildlife Service (Service), propose to list three Tennessee and Cumberland River basin mussel species, the Tennessee clubshell (Pleurobema oviforme), Tennessee pigtoe (Pleuronaia barnesiana), and Cumberland moccasinshell (Medionidus conradicus), as endangered species under the Endangered Species Act of 1973, as amended (Act). This determination also serves as our 12-month finding on a petition to list the three species. After a review of the best available scientific and commercial information, we find that listing the Tennessee clubshell, Tennessee pigtoe, and Cumberland moccasinshell as endangered species is warranted. If we finalize this rule as proposed, it would extend the Act's protections to these species.

We, the U.S. Fish and Wildlife Service (Service), propose to list the salamander mussel (Simpsonaias ambigua), a freshwater mussel species from the United States (Arkansas, Illinois, Indiana, Iowa, Kentucky, Michigan, Minnesota, Missouri, New York, Ohio, Pennsylvania, Tennessee, West Virginia, and Wisconsin) and Canada (Ontario), as an endangered species under the Endangered Species Act of 1973, as amended (Act). This determination also serves as our 12-month finding on a petition to list the salamander mussel. After a review of the best available scientific and commercial information, we find that listing the species is warranted. Accordingly, we propose to list the salamander mussel as an endangered species under the Act. We also propose to designate critical habitat for the salamander mussel under the Act. In total, approximately 2,012 river miles (3,238 kilometers) in Indiana, Kentucky, Michigan, Minnesota, New York, Ohio, Pennsylvania, Tennessee, West Virginia, and Wisconsin fall within the boundaries of the proposed critical habitat designation. We announce the availability of a draft economic analysis (DEA) of the proposed designation of critical habitat for the salamander mussel. If we finalize this rule as proposed, it would extend the Act's protections to this species and its designated critical habitat.

We, the U.S. Fish and Wildlife Service (Service), propose to list the Brawleys Fork crayfish (Cambarus williami), a freshwater crayfish species from Tennessee, as a threatened species and designate critical habitat under the Endangered Species Act of 1973, as amended (Act). This determination also serves as our 12-month finding on a petition to list the Brawleys Fork crayfish. After a review of the best available scientific and commercial information, we find that listing the species is warranted. Accordingly, we propose to list the Brawleys Fork crayfish as a threatened species with a rule issued under section 4(d) of the Act (``4(d) rule''). If we finalize this rule as proposed, it would add this species to the List of Endangered and Threatened Wildlife and extend the Act's protections to the species. We also propose to designate critical habitat for the Brawleys Fork crayfish under the Act. In total, approximately 86.6 river miles (139.4 river kilometers) in Cannon, Rutherford, and Warren Counties, Tennessee, fall within the boundaries of the proposed critical habitat designation. We also announce the availability of a draft economic analysis of the proposed designation of critical habitat for Brawleys Fork crayfish.
