Proposed Endangered Status for the Chupadera Springsnail (Pyrgulopsis chupaderae) and Proposed Designation of Critical Habitat: Proposed rule; reopening of comment period.

We, the U.S. Fish and Wildlife Service (Service), announce the reopening of the public comment period on our August 2, 2011, proposed rule to list the Chupadera springsnail (Pyrgulopsis chupaderae) as endangered and designate critical habitat under the Endangered Species Act of 1973, as amended. We are reopening the comment period to allow all interested parties an additional opportunity to comment on the proposed rule and previously completed drafts of the economic analysis and environmental assessment. Comments previously submitted need not be resubmitted, as they will be fully considered in preparation of the final rule.
