2018-21798: Endangered and Threatened Wildlife and Plants; Threatened Species Status With Section 4(d) Rule and Critical Habitat Designation for Atlantic Pigtoe

Summary

We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the Atlantic pigtoe (Fusconaia masoni) as endangered or threatened under the Endangered Species Act of 1973, as amended (Act). The Atlantic pigtoe is a freshwater mussel native to Virginia, North Carolina, South Carolina, and Georgia. After review of the best available scientific and commercial information, we find that listing the Atlantic pigtoe as a threatened species is warranted. Accordingly, we propose to list it as a threatened species with a rule issued under section 4(d) of the Act ("4(d) rule"). We also propose to designate critical habitat under the Act. In total, approximately 542 river miles (872 river kilometers) in Virginia and North Carolina fall within the boundaries of the proposed critical habitat designation. Finally, we announce the availability of a draft economic analysis (DEA) of the proposed designation of critical habitat.
