This bill seeks to nullify a specific final rule issued by the United States Fish and Wildlife Service (FWS) on June 4, 2024. The targeted FWS rule designates several species of mussels, such as the Guadalupe Fatmucket, Texas Fatmucket, and Balcones Spike, as endangered or threatened species . Additionally, the FWS rule establishes critical habitat for these species and includes a Section 4(d) rule for the Texas Fawnsfoot. If enacted, this legislation would ensure that the FWS rule regarding these mussel species and their habitats has no legal force or effect , preventing its implementation.
