This bill requires the U.S. Fish and Wildlife Service and the National Oceanic and Atmospheric Administration to withdraw three proposed regulatory changes to the Endangered Species Act that were published in June 2023. The proposed rules involved updating how federal agencies cooperate on endangered species issues, how species are listed as endangered or threatened, and how critical habitats are designated. The bill prohibits these agencies from finalizing, implementing, or enforcing these rules in any form. The legislation was introduced by a group of Republican senators in September 2023 and would effectively block the regulatory updates before they could take effect.
