Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the United States Fish and Wildlife Service relating to "Endangered and Threatened Wildlife and Plants; Endangered Species Status for the San Francisco Bay-Delta Distinct Population Segment of the Longfin Smelt".

This joint resolution, H. J. RES. 78, aims to exercise congressional authority under chapter 8 of title 5, United States Code, to disapprove a specific administrative rule. The rule in question was submitted by the United States Fish and Wildlife Service and pertains to the "Endangered and Threatened Wildlife and Plants; Endangered Species Status for the San Francisco Bay-Delta Distinct Population Segment of the Longfin Smelt."

By passing this resolution, Congress intends to prevent the aforementioned rule from taking effect. If enacted, this disapproval would mean the Fish and Wildlife Service's determination to list the San Francisco Bay-Delta Longfin Smelt as an endangered species would be nullified, ensuring it has no legal force or effect.
