Critical Habitat Designation for Four Vernal Pool Crustaceans and Eleven Vernal Pool Plants in California and Southern Oregon; proposed rule; notice of availability of draft economic analysis; extension of comment period.

We, the U.S. Fish and Wildlife Service (Service) announce the availability of the draft economic analysis for the proposed designation of critical habitat for four vernal pool crustaceans and eleven vernal pool plants in California and southern Oregon. The economic analysis identifies potential costs between $6 and $7 million per year as a result of the designation of critical habitat, including those costs coextensive with listing. We are extending the comment period for the proposal to designate critical habitat for these species to allow all interested parties to comment simultaneously on the proposed rule and the associated draft economic analysis. Comments previously submitted need not be resubmitted as they will be incorporated into the public record as part of this extended comment period, and will be fully considered in the final rule.
