90-Day Finding on a Petition To Delist the Idaho Springsnail; 90-Day Finding on a Petition To List the Jackson Lake Springsnail, Harney Lake Springsnail, and Columbia Springsnail; and Initiation of a 5-Year Review for the Idaho Springsnail

We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on a petition to remove (first petition) the Idaho springsnail (Pyrgulopsis idahoensis) from the Federal List of Endangered and Threatened Wildlife and Plants (List) pursuant to the Endangered Species Act (Act), as well as a 90-day finding on a petition to add (second petition) the Jackson Lake springsnail (P. robusta), Harney Lake springsnail (P. hendersoni), and Columbia springsnail (P. spp. A) to the List as endangered or threatened. We find the first petition presents substantial scientific information that delisting the Idaho springsnail may be warranted. We also find that the second petition presents substantial scientific information that listing the Jackson Lake springsnail, Harney Lake springsnail, and Columbia springsnail may be warranted. We are requesting submission of any new information on the Idaho springsnail since its original listing as an endangered species in 1992, and information on the Jackson Lake springsnail, Harney Lake springsnail, and Columbia springsnail. Following this 12-month status review, we will issue 12-month findings on the petition to delist the Idaho springsnail and the petition to list the Jackson Lake springsnail, Harney Lake springsnail, and Columbia springsnail. Section 4(c)(2)(A) of the Act also requires a status review of listed species at least once every 5 years. We are therefore electing to conduct these reviews simultaneously. At the conclusion of these reviews, we will issue the 12-month findings on the petitions, as provided in section 4(b)(3)(B) of the Act, and make the requisite recommendation under section 4(c)(2)(B) of the Act based on the results of the 5-year review for the Idaho springsnail.
