Withdrawal of Proposed Rule To List the Southwestern Washington/Columbia River Distinct Population Segment of Coastal Cutthroat Trout (Oncorhynchus clarki clarki) as Threatened

We, the U.S. Fish and Wildlife Service (Service), have determined that the proposed listing of the Southwestern Washington/ Columbia River Distinct Population Segment (DPS) of coastal cutthroat trout as a threatened species under the Endangered Species Act of 1973, as amended (Act), is not warranted. We therefore withdraw our proposed rule (64 FR 16397; April 5, 1999) to list the DPS under the Act. Although we had earlier concluded that this DPS did not warrant listing under the Act, as a result of litigation we have reconsidered whether the marine and estuarine areas of the DPS may warrant listing if they constitute a significant portion of the range of the DPS. Based upon a thorough review of the best available scientific and commercial data, we have determined that the threats to coastal cutthroat trout in the marine and estuarine areas of its range within the DPS, as analyzed under the five listing factors described in section 4(a)(1) of the Act, are not likely to endanger the species now or in the foreseeable future throughout this portion of its range. We, therefore, again withdraw our proposed rule, as we have determined that the coastal cutthroat trout is not likely to become endangered now or in the foreseeable future throughout all or a significant portion of its range within the Southwestern Washington/Columbia River DPS.
