Proposed Designation of Critical Habitat for the Southern California Distinct Vertebrate Population Segment of the Mountain Yellow-Legged Frog (Rana muscosa);reopening of public comment period and notice of availability of draft economic analysis.

We, the U.S. Fish and Wildlife Service (Service), announce the reopening of the public comment period on the proposed designation of critical habitat for the southern California distinct vertebrate population segment of the mountain yellow-legged frog (Rana muscosa), and the availability of a draft economic analysis of the proposed designation of critical habitat. The draft economic analysis estimates the potential total future impacts, including costs resulting from modifications to fishing and other types of activities, to range from $11.4 million to $12.9 million (undiscounted) over 20 years. Discounted future costs are estimated to be $7.5 million to $8.9 million over this same time period ($704,000 to $842,000 annually) using a real rate of seven percent, or $9.3 million to $10.8 million ($626,000 to $725,000 annually) using a real rate of three percent. We are reopening the comment period to allow all interested parties an opportunity to comment simultaneously on the proposed rule and the associated draft economic analysis. Comments previously submitted on the proposed rule need not be resubmitted as they have already been incorporated into the public record and will be fully considered in our final determination.
