The purpose of this legislation is to nullify a specific rule established by the United States Fish and Wildlife Service regarding the protection of certain mussel species in Texas. The rule in question designates several mussels as endangered or threatened and outlines their critical habitats, which are areas essential for their survival. The key provision of this legislation states that the final rule concerning the Guadalupe Fatmucket, Texas Fatmucket, Guadalupe Orb, Texas Pimpleback, Balcones Spike, and False Spike mussels, as well as the Texas Fawnsfoot, will no longer be effective.
