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, announce the reopening of the public comment period on our August 2, 2011, proposed endangered status and designation of critical habitat for the Chupadera springsnail (Pyrgulopsis chupaderae) under the Endangered Species Act of 1973, as amended (Act). We also announce the availability of a draft economic analysis and draft environmental assessment of the proposed designation of critical habitat and an amended required determinations section of the proposal. We are reopening the comment period to allow all interested parties an opportunity to comment simultaneously on the revised proposed rule, the associated draft economic analysis and draft environmental assessment, and the amended required determinations section. Comments previously submitted need not be resubmitted, as they will be fully considered in preparation of the final rule.
