To provide that the final rule of the United States Fish and Wildlife Service titled "Endangered and Threatened Wildlife and Plants; Endangered Species Status With Critical Habitat for Guadalupe Fatmucket, Texas Fatmucket, Guadalupe Orb, Texas Pimpleback, Balcones Spike, and False Spike, and Threatened Species Status With Section 4(d) Rule and Critical Habitat for Texas Fawnsfoot" shall have no force or effect.

Voids federal endangered and critical-habitat protections for six freshwater mussels. The bill invalidates the U.S. Fish and Wildlife Service final rule (published June 4, 2024) that would have listed Guadalupe fatmucket, Texas fatmucket, Guadalupe orb, Texas pimpleback, Balcones spike, and false spike as endangered or threatened and that included a Section 4(d) rule and critical habitat for Texas fawnsfoot. By declaring that rule void, the measure preserves the legal status quo that existed before the rule and prevents the protections and habitat designations in that rule from taking effect.
