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 measure cancels a U.S. Fish and Wildlife Service rule that listed the San Francisco Bay–Delta longfin smelt as an endangered species. By overturning that rule, it removes the species’ federal protections under the Endangered Species Act. The rule it targets was published on July 30, 2024, and specifically covered the Bay–Delta population of the longfin smelt, a Pacific Coast fish .

• In plain terms: the fish would no longer be treated as endangered at the federal level, and the protections that come with that status would not apply .
