Designation of Critical Habitat for the Southwest Alaska Distinct Population Segment of the Northern Sea Otter: Proposed rule; extension of comment period, notice of availability of draft economic analysis, and amended required eterminations.

We, the U.S. Fish and Wildlife Service, announce the extension of the public comment period on the proposed designation of critical habitat for the southwest Alaska Distinct Population Segment (DPS) of the northern sea otter (Enhydra lutris kenyoni) under the Endangered Species Act of 1973, as amended. We also announce the availability of a draft economic analysis (DEA) and an amended required determinations section of the proposal. We are extending the comment period for an additional 30 days from the date of this notice to allow all interested parties an opportunity to comment simultaneously on the revised proposed rule, the associated DEA, and the amended required determinations section. If you submitted comments previously, you do not need to resubmit them because we have already incorporated them into the public record and will fully consider them in preparation of the final rule.
