Interior Department, Fish and Wildlife Service
We, the U.S. Fish and Wildlife Service (Service), withdraw the proposed rule to list the headwater chub (Gila nigra) and a distinct population segment (DPS) of the roundtail chub (Gila robusta) from the lower Colorado River basin as threatened species under the Endangered Species Act (Act). This withdrawal is based on a thorough review of the best scientific and commercial data available, which indicate that the headwater chub and the roundtail chub DPS are not discrete taxonomic entities and do not meet the definition of a species under the Act. These fish are now recognized as a part of a single taxonomic species--the roundtail chub (Gila robusta). Because the entities previously proposed for listing are no longer recognized as species, as defined by the Act, we have determined that they are not listable entities and we are withdrawing our proposed rule to add them to the List of Endangered and Threatened Wildlife. Section 4(b)(6) of the Act and implementing regulations at 50 CFR 424.17 provide that the Service must, within 1 year of a proposed rule to list, delist, or reclassify species, or to designate or revise critical habitat, withdraw the proposal if the available evidence does not justify the proposed action. The document withdrawing the rule must set forth the basis upon which the proposed rule has been found not to be supported by available evidence. Once withdrawn, the action may not be re-proposed unless sufficient new information is available.

ACTION: Proposed rule; withdrawal. SUMMARY: We, the U.S. Fish and Wildlife Service (Service), withdraw the proposed rule to list the headwater chub ( Gila nigra ) and a distinct population segment (DPS) of the roundtail chub ( Gila robusta ) from the lower Colorado River basin as threatened species under the Endangered Species Act (Act). This withdrawal is based on a thorough review of the best scientific and commercial data available, which indicate that the headwater chub and ( printed page 16982) the roundtail chub DPS are not discrete taxonomic entities and do not meet the definition of a species under the Act. These fish are now recognized as a part of a single taxonomic species—the roundtail chub ( Gila robusta ). Because the entities previously proposed for listing are no longer recognized as species, as defined by the Act, we have determined that they are not listable entities and we are withdrawing our proposed rule to add them to the List of Endangered and Threatened Wildlife. Section 4(b)(6) of the Act and implementing regulations at 50 CFR 424.17 provide that the Service must, within 1 year of a proposed rule to list, delist, or reclassify species, or to designate or revise critical habitat, withdraw the proposal if the available evidence does not justify the proposed action.
